Right now `rustc`\nshells out to the system linker (`gcc` on most systems, `link.exe` on MSVC), so\nit makes sense to provide extra command line arguments, but this will not\nalways be the case. In the future `rustc` may use LLVM directly to link native\nlibraries, in which case `link_args` will have no meaning. You can achieve the\nsame effect as the `link_args` attribute with the `-C link-args` argument to\n`rustc`.\n\nIt is highly recommended to *not* use this attribute, and rather use the more\nformal `#[link(...)]` attribute on `extern` blocks instead.\n" } , LintCompletion { label : "cfg_version" , description : "# `cfg_version`\n\nThe tracking issue for this feature is: [#64796]\n\n[#64796]: https://github.com/rust-lang/rust/issues/64796\n\n------------------------\n\nThe `cfg_version` feature makes it possible to execute different code\ndepending on the compiler version.\n\n## Examples\n\n```rust\n#![feature(cfg_version)]\n\n#[cfg(version(\"1.42\"))]\nfn a() {\n // ...\n}\n\n#[cfg(not(version(\"1.42\")))]\nfn a() {\n // ...\n}\n\nfn b() {\n if cfg!(version(\"1.42\")) {\n // ...\n } else {\n // ...\n }\n}\n```\n" } , LintCompletion { label : "ffi_const" , description : "# `ffi_const`\n\nThe `#[ffi_const]` attribute applies clang's `const` attribute to foreign\nfunctions declarations.\n\nThat is, `#[ffi_const]` functions shall have no effects except for its return\nvalue, which can only depend on the values of the function parameters, and is\nnot affected by changes to the observable state of the program.\n\nApplying the `#[ffi_const]` attribute to a function that violates these\nrequirements is undefined behaviour.\n\nThis attribute enables Rust to perform common optimizations, like sub-expression\nelimination, and it can avoid emitting some calls in repeated invocations of the\nfunction with the same argument values regardless of other operations being\nperformed in between these functions calls (as opposed to `#[ffi_pure]`\nfunctions).\n\n## Pitfalls\n\nA `#[ffi_const]` function can only read global memory that would not affect\nits return value for the whole execution of the program (e.g. immutable global\nmemory). `#[ffi_const]` functions are referentially-transparent and therefore\nmore strict than `#[ffi_pure]` functions.\n\nA common pitfall involves applying the `#[ffi_const]` attribute to a\nfunction that reads memory through pointer arguments which do not necessarily\npoint to immutable global memory.\n\nA `#[ffi_const]` function that returns unit has no effect on the abstract\nmachine's state, and a `#[ffi_const]` function cannot be `#[ffi_pure]`.\n\nA `#[ffi_const]` function must not diverge, neither via a side effect (e.g. a\ncall to `abort`) nor by infinite loops.\n\nWhen translating C headers to Rust FFI, it is worth verifying for which targets\nthe `const` attribute is enabled in those headers, and using the appropriate\n`cfg` macros in the Rust side to match those definitions.

A generator is a \"resumable function\" that syntactically\nresembles a closure but compiles to much different semantics in the compiler\nitself. The primary feature of a generator is that it can be suspended during\nexecution to be resumed at a later date. Generators use the `yield` keyword to\n\"return\", and then the caller can `resume` a generator to resume execution just\nafter the `yield` keyword.\n\nGenerators are an extra-unstable feature in the compiler right now. Added in\n[RFC 2033] they're mostly intended right now as a information/constraint\ngathering phase. The intent is that experimentation can happen on the nightly\ncompiler before actual stabilization. A further RFC will be required to\nstabilize generators/coroutines and will likely contain at least a few small\ntweaks to the overall design.\n\n[RFC 2033]: https://github.com/rust-lang/rfcs/pull/2033\n\nA syntactical example of a generator is:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::{Generator, GeneratorState};\nuse std::pin::Pin;\n\nfn main() {\n let mut generator = || {\n yield 1;\n return \"foo\"\n };\n\n match Pin::new(&mut generator).resume(()) {\n GeneratorState::Yielded(1) => {}\n _ => panic!(\"unexpected value from resume\"),\n }\n match Pin::new(&mut generator).resume(()) {\n GeneratorState::Complete(\"foo\") => {}\n _ => panic!(\"unexpected value from resume\"),\n }\n}\n```\n\nGenerators are closure-like literals which can contain a `yield` statement. The\n`yield` statement takes an optional expression of a value to yield out of the\ngenerator. All generator literals implement the `Generator` trait in the\n`std::ops` module. The `Generator` trait has one main method, `resume`, which\nresumes execution of the generator at the previous suspension point.\n\nAn example of the control flow of generators is that the following example\nprints all numbers in order:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::Generator;\nuse std::pin::Pin;\n\nfn main() {\n let mut generator = || {\n println!(\"2\");\n yield;\n println!(\"4\");\n };\n\n println!(\"1\");\n Pin::new(&mut generator).resume(());\n println!(\"3\");\n Pin::new(&mut generator).resume(());\n println!(\"5\");\n}\n```\n\nAt this time the main intended use case of generators is an implementation\nprimitive for async/await syntax, but generators will likely be extended to\nergonomic implementations of iterators and other primitives in the future.\nFeedback on the design and usage is always appreciated!\n\n### The `Generator` trait\n\nThe `Generator` trait in `std::ops` currently looks like:\n\n```rust\n# #![feature(arbitrary_self_types, generator_trait)]\n# use std::ops::GeneratorState;\n# use std::pin::Pin;\n\npub trait Generator {\n type Yield;\n type Return;\n fn resume(self: Pin<&mut Self>, resume: R) -> GeneratorState;\n}\n```\n\nThe `Generator::Yield` type is the type of values that can be yielded with the\n`yield` statement. The `Generator::Return` type is the returned type of the\ngenerator. This is typically the last expression in a generator's definition or\nany value passed to `return` in a generator. The `resume` function is the entry\npoint for executing the `Generator` itself.\n\nThe return value of `resume`, `GeneratorState`, looks like:\n\n```rust\npub enum GeneratorState {\n Yielded(Y),\n Complete(R),\n}\n```\n\nThe `Yielded` variant indicates that the generator can later be resumed. This\ncorresponds to a `yield` point in a generator. The `Complete` variant indicates\nthat the generator is complete and cannot be resumed again. Calling `resume`\nafter a generator has returned `Complete` will likely result in a panic of the\nprogram.\n\n### Closure-like semantics\n\nThe closure-like syntax for generators alludes to the fact that they also have\nclosure-like semantics. Namely:\n\n* When created, a generator executes no code. A closure literal does not\n actually execute any of the closure's code on construction, and similarly a\n generator literal does not execute any code inside the generator when\n constructed.\n\n* Generators can capture outer variables by reference or by move, and this can\n be tweaked with the `move` keyword at the beginning of the closure. Like\n closures all generators will have an implicit environment which is inferred by\n the compiler. Outer variables can be moved into a generator for use as the\n generator progresses.\n\n* Generator literals produce a value with a unique type which implements the\n `std::ops::Generator` trait. This allows actual execution of the generator\n through the `Generator::resume` method as well as also naming it in return\n types and such.\n\n* Traits like `Send` and `Sync` are automatically implemented for a `Generator`\n depending on the captured variables of the environment. Unlike closures,\n generators also depend on variables live across suspension points. This means\n that although the ambient environment may be `Send` or `Sync`, the generator\n itself may not be due to internal variables live across `yield` points being\n not-`Send` or not-`Sync`. Note that generators do\n not implement traits like `Copy` or `Clone` automatically.\n\n* Whenever a generator is dropped it will drop all captured environment\n variables.\n\n### Generators as state machines\n\nIn the compiler, generators are currently compiled as state machines. Each\n`yield` expression will correspond to a different state that stores all live\nvariables over that suspension point. Resumption of a generator will dispatch on\nthe current state and then execute internally until a `yield` is reached, at\nwhich point all state is saved off in the generator and a value is returned.\n\nLet's take a look at an example to see what's going on here:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::Generator;\nuse std::pin::Pin;\n\nfn main() {\n let ret = \"foo\";\n let mut generator = move || {\n yield 1;\n return ret\n };\n\n Pin::new(&mut generator).resume(());\n Pin::new(&mut generator).resume(());\n}\n```\n\nThis generator literal will compile down to something similar to:\n\n```rust\n#![feature(arbitrary_self_types, generators, generator_trait)]\n\nuse std::ops::{Generator, GeneratorState};\nuse std::pin::Pin;\n\nfn main() {\n let ret = \"foo\";\n let mut generator = {\n enum __Generator {\n Start(&'static str),\n Yield1(&'static str),\n Done,\n }\n\n impl Generator for __Generator {\n type Yield = i32;\n type Return = &'static str;\n\n fn resume(mut self: Pin<&mut Self>, resume: ()) -> GeneratorState {\n use std::mem;\n match mem::replace(&mut *self, __Generator::Done) {\n __Generator::Start(s) => {\n *self = __Generator::Yield1(s);\n GeneratorState::Yielded(1)\n }\n\n __Generator::Yield1(s) => {\n *self = __Generator::Done;\n GeneratorState::Complete(s)\n }\n\n __Generator::Done => {\n panic!(\"generator resumed after completion\")\n }\n }\n }\n }\n\n __Generator::Start(ret)\n };\n\n Pin::new(&mut generator).resume(());\n Pin::new(&mut generator).resume(());\n}\n```\n\nNotably here we can see that the compiler is generating a fresh type,\n`__Generator` in this case. This type has a number of states (represented here\nas an `enum`) corresponding to each of the conceptual states of the generator.\nAt the beginning we're closing over our outer variable `foo` and then that\nvariable is also live over the `yield` point, so it's stored in both states.\n\nWhen the generator starts it'll immediately yield 1, but it saves off its state\njust before it does so indicating that it has reached the yield point.

The syntax isn't final, either. We may need an alternative syntax for Rust 2015 because, in Rust 2015, expressions like `[e; dyn(1)]` would be ambiguous. One possible alternative proposed in the RFC is `[e; n]`: if `n` captures one or more local variables, then it is considered as `[e; dyn n]`.\n\n## Advisory on stack usage\n\nIt's advised not to casually use the `#![feature(unsized_locals)]` feature. Typical use-cases are:\n\n- When you need a by-value trait objects.\n- When you really need a fast allocation of small temporary arrays.\n\nAnother pitfall is repetitive allocation and temporaries. Currently the compiler simply extends the stack frame every time it encounters an unsized assignment. So for example, the code\n\n```rust\n#![feature(unsized_locals)]\n\nfn main() {\n let x: Box<[i32]> = Box::new([1, 2, 3, 4, 5]);\n let _x = {{{{{{{{{{*x}}}}}}}}}};\n}\n```\n\nand the code\n\n```rust\n#![feature(unsized_locals)]\n\nfn main() {\n for _ in 0..10 {\n let x: Box<[i32]> = Box::new([1, 2, 3, 4, 5]);\n let _x = *x;\n }\n}\n```\n\nwill unnecessarily extend the stack frame.\n" } , LintCompletion { label : "or_patterns" , description : "# `or_patterns`\n\nThe tracking issue for this feature is: [#54883]\n\n[#54883]: https://github.com/rust-lang/rust/issues/54883\n\n------------------------\n\nThe `or_pattern` language feature allows `|` to be arbitrarily nested within\na pattern, for example, `Some(A(0) | B(1 | 2))` becomes a valid pattern.\n\n## Examples\n\n```rust,ignore\n#![feature(or_patterns)]\n\npub enum Foo {\n Bar,\n Baz,\n Quux,\n}\n\npub fn example(maybe_foo: Option) {\n match maybe_foo {\n Some(Foo::Bar | Foo::Baz) => {\n println!(\"The value contained `Bar` or `Baz`\");\n }\n Some(_) => {\n println!(\"The value did not contain `Bar` or `Baz`\");\n }\n None => {\n println!(\"The value was `None`\");\n }\n }\n}\n```\n" } , LintCompletion { label : "member_constraints" , description : "# `member_constraints`\n\nThe tracking issue for this feature is: [#61997]\n\n[#61997]: https://github.com/rust-lang/rust/issues/61997\n\n------------------------\n\nThe `member_constraints` feature gate lets you use `impl Trait` syntax with\nmultiple unrelated lifetime parameters.\n\nA simple example is:\n\n```rust\n#![feature(member_constraints)]\n\ntrait Trait<'a, 'b> { }\nimpl Trait<'_, '_> for T {}\n\nfn foo<'a, 'b>(x: &'a u32, y: &'b u32) -> impl Trait<'a, 'b> {\n (x, y)\n}\n\nfn main() { }\n```\n\nWithout the `member_constraints` feature gate, the above example is an\nerror because both `'a` and `'b` appear in the impl Trait bounds, but\nneither outlives the other.\n" } , LintCompletion { label : "optin_builtin_traits" , description : "# `optin_builtin_traits`\n\nThe tracking issue for this feature is [#13231] \n\n[#13231]: https://github.com/rust-lang/rust/issues/13231\n\n----\n\nThe `optin_builtin_traits` feature gate allows you to define auto traits.\n\nAuto traits, like [`Send`] or [`Sync`] in the standard library, are marker traits\nthat are automatically implemented for every type, unless the type, or a type it contains, \nhas explicitly opted out via a negative impl.

These automatic impls contain a where clause for each field\nof the form `T: AutoTrait`, where `T` is the type of the field and\n`AutoTrait` is the auto trait in question. As an example, consider the\nstruct `List` and the auto trait `Send`:\n\n```rust\nstruct List {\n data: T,\n next: Option>>,\n}\n```\n\nPresuming that there is no explicit impl of `Send` for `List`, the\ncompiler will supply an automatic impl of the form:\n\n```rust\nstruct List {\n data: T,\n next: Option>>,\n}\n\nunsafe impl Send for List\nwhere\n T: Send, // from the field `data`\n Option>>: Send, // from the field `next`\n{ }\n```\n\nExplicit impls may be either positive or negative. They take the form:\n\n```rust,ignore\nimpl<...> AutoTrait for StructName<..> { }\nimpl<...> !AutoTrait for StructName<..> { }\n```\n\n## Coinduction: Auto traits permit cyclic matching\n\nUnlike ordinary trait matching, auto traits are **coinductive**. This\nmeans, in short, that cycles which occur in trait matching are\nconsidered ok. As an example, consider the recursive struct `List`\nintroduced in the previous section. In attempting to determine whether\n`List: Send`, we would wind up in a cycle: to apply the impl, we must\nshow that `Option>: Send`, which will in turn require\n`Box: Send` and then finally `List: Send` again. Under ordinary\ntrait matching, this cycle would be an error, but for an auto trait it\nis considered a successful match.\n\n## Items\n\nAuto traits cannot have any trait items, such as methods or associated types. This ensures that we can generate default implementations.\n\n## Supertraits\n\nAuto traits cannot have supertraits.

The marker is the attribute `#[lang = \"...\"]` and there are\nvarious different values of `...`, i.e. various different 'lang\nitems'.\n\nFor example, `Box` pointers require two lang items, one for allocation\nand one for deallocation. A freestanding program that uses the `Box`\nsugar for dynamic allocations via `malloc` and `free`:\n\n```rust,ignore\n#![feature(lang_items, box_syntax, start, libc, core_intrinsics)]\n#![no_std]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\nextern crate libc;\n\n#[lang = \"owned_box\"]\npub struct Box(*mut T);\n\n#[lang = \"exchange_malloc\"]\nunsafe fn allocate(size: usize, _align: usize) -> *mut u8 {\n let p = libc::malloc(size as libc::size_t) as *mut u8;\n\n // Check if `malloc` failed:\n if p as usize == 0 {\n intrinsics::abort();\n }\n\n p\n}\n\n#[lang = \"box_free\"]\nunsafe fn box_free(ptr: *mut T) {\n libc::free(ptr as *mut libc::c_void)\n}\n\n#[start]\nfn main(_argc: isize, _argv: *const *const u8) -> isize {\n let _x = box 1;\n\n 0\n}\n\n#[lang = \"eh_personality\"] extern fn rust_eh_personality() {}\n#[lang = \"panic_impl\"] extern fn rust_begin_panic(info: &PanicInfo) -> ! { unsafe { intrinsics::abort() } }\n#[no_mangle] pub extern fn rust_eh_register_frames () {}\n#[no_mangle] pub extern fn rust_eh_unregister_frames () {}\n```\n\nNote the use of `abort`: the `exchange_malloc` lang item is assumed to\nreturn a valid pointer, and so needs to do the check internally.\n\nOther features provided by lang items include:\n\n- overloadable operators via traits: the traits corresponding to the\n `==`, `<`, dereferencing (`*`) and `+` (etc.) operators are all\n marked with lang items; those specific four are `eq`, `ord`,\n `deref`, and `add` respectively.\n- stack unwinding and general failure; the `eh_personality`,\n `panic` and `panic_bounds_checks` lang items.\n- the traits in `std::marker` used to indicate types of\n various kinds; lang items `send`, `sync` and `copy`.\n- the marker types and variance indicators found in\n `std::marker`; lang items `covariant_type`,\n `contravariant_lifetime`, etc.\n\nLang items are loaded lazily by the compiler; e.g. if one never uses\n`Box` then there is no need to define functions for `exchange_malloc`\nand `box_free`. `rustc` will emit an error when an item is needed\nbut not found in the current crate or any that it depends on.\n\nMost lang items are defined by `libcore`, but if you're trying to build\nan executable without the standard library, you'll run into the need\nfor lang items. The rest of this page focuses on this use-case, even though\nlang items are a bit broader than that.\n\n### Using libc\n\nIn order to build a `#[no_std]` executable we will need libc as a dependency.\nWe can specify this using our `Cargo.toml` file:\n\n```toml\n[dependencies]\nlibc = { version = \"0.2.14\", default-features = false }\n```\n\nNote that the default features have been disabled. This is a critical step -\n**the default features of libc include the standard library and so must be\ndisabled.**\n\n### Writing an executable without stdlib\n\nControlling the entry point is possible in two ways: the `#[start]` attribute,\nor overriding the default shim for the C `main` function with your own.\n\nThe function marked `#[start]` is passed the command line parameters\nin the same format as C:\n\n```rust,ignore\n#![feature(lang_items, core_intrinsics)]\n#![feature(start)]\n#![no_std]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\n// Pull in the system libc library for what crt0.o likely requires.\nextern crate libc;\n\n// Entry point for this program.\n#[start]\nfn start(_argc: isize, _argv: *const *const u8) -> isize {\n 0\n}\n\n// These functions are used by the compiler, but not\n// for a bare-bones hello world. These are normally\n// provided by libstd.\n#[lang = \"eh_personality\"]\n#[no_mangle]\npub extern fn rust_eh_personality() {\n}\n\n#[lang = \"panic_impl\"]\n#[no_mangle]\npub extern fn rust_begin_panic(info: &PanicInfo) -> ! {\n unsafe { intrinsics::abort() }\n}\n```\n\nTo override the compiler-inserted `main` shim, one has to disable it\nwith `#![no_main]` and then create the appropriate symbol with the\ncorrect ABI and the correct name, which requires overriding the\ncompiler's name mangling too:\n\n```rust,ignore\n#![feature(lang_items, core_intrinsics)]\n#![feature(start)]\n#![no_std]\n#![no_main]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\n// Pull in the system libc library for what crt0.o likely requires.\nextern crate libc;\n\n// Entry point for this program.\n#[no_mangle] // ensure that this symbol is called `main` in the output\npub extern fn main(_argc: i32, _argv: *const *const u8) -> i32 {\n 0\n}\n\n// These functions are used by the compiler, but not\n// for a bare-bones hello world.

You may observe this via linker error messages\nsuch as \"```undefined reference to `__rust_probestack'```\".\n\n## More about the language items\n\nThe compiler currently makes a few assumptions about symbols which are\navailable in the executable to call. Normally these functions are provided by\nthe standard library, but without it you must define your own. These symbols\nare called \"language items\", and they each have an internal name, and then a\nsignature that an implementation must conform to.\n\nThe first of these functions, `rust_eh_personality`, is used by the failure\nmechanisms of the compiler. This is often mapped to GCC's personality function\n(see the [libstd implementation][unwind] for more information), but crates\nwhich do not trigger a panic can be assured that this function is never\ncalled.

Negative impls are a commitment not to implement the given trait for the named types.\n\n## Orphan and overlap rules\n\nNegative impls must obey the same orphan rules as a positive impl. This implies you cannot add a negative impl for types defined in upstream crates and so forth.\n\nSimilarly, negative impls cannot overlap with positive impls, again using the same \"overlap\" check that we ordinarily use to determine if two impls overlap. (Note that positive impls typically cannot overlap with one another either, except as permitted by specialization.)\n\n## Interaction with auto traits\n\nDeclaring a negative impl `impl !SomeAutoTrait for SomeType` for an\nauto-trait serves two purposes:\n\n* as with any trait, it declares that `SomeType` will never implement `SomeAutoTrait`;\n* it disables the automatic `SomeType: SomeAutoTrait` impl that would otherwise have been generated.\n\nNote that, at present, there is no way to indicate that a given type\ndoes not implement an auto trait *but that it may do so in the\nfuture*. For ordinary types, this is done by simply not declaring any\nimpl at all, but that is not an option for auto traits. A workaround\nis that one could embed a marker type as one of the fields, where the\nmarker type is `!AutoTrait`.\n\n## Immediate uses\n\nNegative impls are used to declare that `&T: !DerefMut` and `&mut T: !Clone`, as required to fix the soundness of `Pin` described in [#66544](https://github.com/rust-lang/rust/issues/66544).\n\nThis serves two purposes:\n\n* For proving the correctness of unsafe code, we can use that impl as evidence that no `DerefMut` or `Clone` impl exists.\n* It prevents downstream crates from creating such impls.\n" } , LintCompletion { label : "abi_ptx" , description : "# `abi_ptx`\n\nThe tracking issue for this feature is: [#38788]\n\n[#38788]: https://github.com/rust-lang/rust/issues/38788\n\n------------------------\n\nWhen emitting PTX code, all vanilla Rust functions (`fn`) get translated to\n\"device\" functions.

This is\ngenerally unwanted unless you are building another plugin.\n\nThe usual practice is to put compiler plugins in their own crate, separate from\nany `macro_rules!` macros or ordinary Rust code meant to be used by consumers\nof a library.\n\n# Lint plugins\n\nPlugins can extend [Rust's lint\ninfrastructure](../../reference/attributes/diagnostics.md#lint-check-attributes) with\nadditional checks for code style, safety, etc. Now let's write a plugin\n[`lint-plugin-test.rs`](https://github.com/rust-lang/rust/blob/master/src/test/ui-fulldeps/auxiliary/lint-plugin-test.rs)\nthat warns about any item named `lintme`.\n\n```rust,ignore\n#![feature(plugin_registrar)]\n#![feature(box_syntax, rustc_private)]\n\nextern crate rustc_ast;\n\n// Load rustc as a plugin to get macros\nextern crate rustc_driver;\n#[macro_use]\nextern crate rustc_lint;\n#[macro_use]\nextern crate rustc_session;\n\nuse rustc_driver::plugin::Registry;\nuse rustc_lint::{EarlyContext, EarlyLintPass, LintArray, LintContext, LintPass};\nuse rustc_ast::ast;\ndeclare_lint!(TEST_LINT, Warn, \"Warn about items named 'lintme'\");\n\ndeclare_lint_pass!(Pass => [TEST_LINT]);\n\nimpl EarlyLintPass for Pass {\n fn check_item(&mut self, cx: &EarlyContext, it: &ast::Item) {\n if it.ident.name.as_str() == \"lintme\" {\n cx.lint(TEST_LINT, |lint| {\n lint.build(\"item is named 'lintme'\").set_span(it.span).emit()\n });\n }\n }\n}\n\n#[plugin_registrar]\npub fn plugin_registrar(reg: &mut Registry) {\n reg.lint_store.register_lints(&[&TEST_LINT]);\n reg.lint_store.register_early_pass(|| box Pass);\n}\n```\n\nThen code like\n\n```rust,ignore\n#![feature(plugin)]\n#![plugin(lint_plugin_test)]\n\nfn lintme() { }\n```\n\nwill produce a compiler warning:\n\n```txt\nfoo.rs:4:1: 4:16 warning: item is named 'lintme', #[warn(test_lint)] on by default\nfoo.rs:4 fn lintme() { }\n ^~~~~~~~~~~~~~~\n```\n\nThe components of a lint plugin are:\n\n* one or more `declare_lint!` invocations, which define static `Lint` structs;\n\n* a struct holding any state needed by the lint pass (here, none);\n\n* a `LintPass`\n implementation defining how to check each syntax element. A single\n `LintPass` may call `span_lint` for several different `Lint`s, but should\n register them all through the `get_lints` method.\n\nLint passes are syntax traversals, but they run at a late stage of compilation\nwhere type information is available. `rustc`'s [built-in\nlints](https://github.com/rust-lang/rust/blob/master/src/librustc_session/lint/builtin.rs)\nmostly use the same infrastructure as lint plugins, and provide examples of how\nto access type information.\n\nLints defined by plugins are controlled by the usual [attributes and compiler\nflags](../../reference/attributes/diagnostics.md#lint-check-attributes), e.g.\n`#[allow(test_lint)]` or `-A test-lint`. These identifiers are derived from the\nfirst argument to `declare_lint!`, with appropriate case and punctuation\nconversion.\n\nYou can run `rustc -W help foo.rs` to see a list of lints known to `rustc`,\nincluding those provided by plugins loaded by `foo.rs`.\n" } , LintCompletion { label : "concat_idents" , description : "# `concat_idents`\n\nThe tracking issue for this feature is: [#29599]\n\n[#29599]: https://github.com/rust-lang/rust/issues/29599\n\n------------------------\n\nThe `concat_idents` feature adds a macro for concatenating multiple identifiers\ninto one identifier.\n\n## Examples\n\n```rust\n#![feature(concat_idents)]\n\nfn main() {\n fn foobar() -> u32 { 23 }\n let f = concat_idents!(foo, bar);\n assert_eq!(f(), 23);\n}\n```" } , LintCompletion { label : "update_panic_count" , description : "# `update_panic_count`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "fn_traits" , description : "# `fn_traits`\n\nThe tracking issue for this feature is [#29625]\n\nSee Also: [`unboxed_closures`](../language-features/unboxed-closures.md)\n\n[#29625]: https://github.com/rust-lang/rust/issues/29625\n\n----\n\nThe `fn_traits` feature allows for implementation of the [`Fn*`] traits\nfor creating custom closure-like types.\n\n[`Fn*`]: https://doc.rust-lang.org/std/ops/trait.Fn.html\n\n```rust\n#![feature(unboxed_closures)]\n#![feature(fn_traits)]\n\nstruct Adder {\n a: u32\n}\n\nimpl FnOnce<(u32, )> for Adder {\n type Output = u32;\n extern \"rust-call\" fn call_once(self, b: (u32, )) -> Self::Output {\n self.a + b.0\n }\n}\n\nfn main() {\n let adder = Adder { a: 3 };\n assert_eq!(adder(2), 5);\n}\n```\n" } , LintCompletion { label : "try_trait" , description : "# `try_trait`\n\nThe tracking issue for this feature is: [#42327]\n\n[#42327]: https://github.com/rust-lang/rust/issues/42327\n\n------------------------\n\nThis introduces a new trait `Try` for extending the `?` operator to types\nother than `Result` (a part of [RFC 1859]).

The macro is a no-frills\ninterface to LLVM's concept of [module-level inline assembly]. That is,\nall caveats applicable to LLVM's module-level inline assembly apply\nto `global_asm!`.\n\n[module-level inline assembly]: http://llvm.org/docs/LangRef.html#module-level-inline-assembly\n\n`global_asm!` fills a role not currently satisfied by either `asm!`\nor `#[naked]` functions. The programmer has _all_ features of the\nassembler at their disposal. The linker will expect to resolve any\nsymbols defined in the inline assembly, modulo any symbols marked as\nexternal. It also means syntax for directives and assembly follow the\nconventions of the assembler in your toolchain.\n\nA simple usage looks like this:\n\n```rust,ignore\n# #![feature(global_asm)]\n# you also need relevant target_arch cfgs\nglobal_asm!(include_str!(\"something_neato.s\"));\n```\n\nAnd a more complicated usage looks like this:\n\n```rust,ignore\n# #![feature(global_asm)]\n# #![cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n\npub mod sally {\n global_asm!(r#\"\n .global foo\n foo:\n jmp baz\n \"#);\n\n #[no_mangle]\n pub unsafe extern \"C\" fn baz() {}\n}\n\n// the symbols `foo` and `bar` are global, no matter where\n// `global_asm!` was used.\nextern \"C\" {\n fn foo();\n fn bar();\n}\n\npub mod harry {\n global_asm!(r#\"\n .global bar\n bar:\n jmp quux\n \"#);\n\n #[no_mangle]\n pub unsafe extern \"C\" fn quux() {}\n}\n```\n\nYou may use `global_asm!` multiple times, anywhere in your crate, in\nwhatever way suits you. The effect is as if you concatenated all\nusages and placed the larger, single usage in the crate root.\n\n------------------------\n\nIf you don't need quite as much power and flexibility as\n`global_asm!` provides, and you don't mind restricting your inline\nassembly to `fn` bodies only, you might try the\n[asm](asm.md) feature instead.\n" } , LintCompletion { label : "sort_internals" , description : "# `sort_internals`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "test" , description : "# `test`\n\nThe tracking issue for this feature is: None.\n\n------------------------\n\nThe internals of the `test` crate are unstable, behind the `test` flag. The\nmost widely used part of the `test` crate are benchmark tests, which can test\nthe performance of your code. Let's make our `src/lib.rs` look like this\n(comments elided):\n\n```rust,ignore\n#![feature(test)]\n\nextern crate test;\n\npub fn add_two(a: i32) -> i32 {\n a + 2\n}\n\n#[cfg(test)]\nmod tests {\n use super::*;\n use test::Bencher;\n\n #[test]\n fn it_works() {\n assert_eq!(4, add_two(2));\n }\n\n #[bench]\n fn bench_add_two(b: &mut Bencher) {\n b.iter(|| add_two(2));\n }\n}\n```\n\nNote the `test` feature gate, which enables this unstable feature.\n\nWe've imported the `test` crate, which contains our benchmarking support.\nWe have a new function as well, with the `bench` attribute. Unlike regular\ntests, which take no arguments, benchmark tests take a `&mut Bencher`. This\n`Bencher` provides an `iter` method, which takes a closure. This closure\ncontains the code we'd like to benchmark.\n\nWe can run benchmark tests with `cargo bench`:\n\n```bash\n$ cargo bench\n Compiling adder v0.0.1 (file:///home/steve/tmp/adder)\n Running target/release/adder-91b3e234d4ed382a\n\nrunning 2 tests\ntest tests::it_works ... ignored\ntest tests::bench_add_two ... bench: 1 ns/iter (+/- 0)\n\ntest result: ok. 0 passed; 0 failed; 1 ignored; 1 measured\n```\n\nOur non-benchmark test was ignored. You may have noticed that `cargo bench`\ntakes a bit longer than `cargo test`. This is because Rust runs our benchmark\na number of times, and then takes the average. Because we're doing so little\nwork in this example, we have a `1 ns/iter (+/- 0)`, but this would show\nthe variance if there was one.\n\nAdvice on writing benchmarks:\n\n\n* Move setup code outside the `iter` loop; only put the part you want to measure inside\n* Make the code do \"the same thing\" on each iteration; do not accumulate or change state\n* Make the outer function idempotent too; the benchmark runner is likely to run\n it many times\n* Make the inner `iter` loop short and fast so benchmark runs are fast and the\n calibrator can adjust the run-length at fine resolution\n* Make the code in the `iter` loop do something simple, to assist in pinpointing\n performance improvements (or regressions)\n\n## Gotcha: optimizations\n\nThere's another tricky part to writing benchmarks: benchmarks compiled with\noptimizations activated can be dramatically changed by the optimizer so that\nthe benchmark is no longer benchmarking what one expects. For example, the\ncompiler might recognize that some calculation has no external effects and\nremove it entirely.\n\n```rust,ignore\n#![feature(test)]\n\nextern crate test;\nuse test::Bencher;\n\n#[bench]\nfn bench_xor_1000_ints(b: &mut Bencher) {\n b.iter(|| {\n (0..1000).fold(0, |old, new| old ^ new);\n });\n}\n```\n\ngives the following results\n\n```text\nrunning 1 test\ntest bench_xor_1000_ints ... bench: 0 ns/iter (+/- 0)\n\ntest result: ok. 0 passed; 0 failed; 0 ignored; 1 measured\n```\n\nThe benchmarking runner offers two ways to avoid this. Either, the closure that\nthe `iter` method receives can return an arbitrary value which forces the\noptimizer to consider the result used and ensures it cannot remove the\ncomputation entirely. This could be done for the example above by adjusting the\n`b.iter` call to\n\n```rust\n# struct X;\n# impl X { fn iter(&self, _: F) where F: FnMut() -> T {} } let b = X;\nb.iter(|| {\n // Note lack of `;` (could also use an explicit `return`).\n (0..1000).fold(0, |old, new| old ^ new)\n});\n```\n\nOr, the other option is to call the generic `test::black_box` function, which\nis an opaque \"black box\" to the optimizer and so forces it to consider any\nargument as used.\n\n```rust\n#![feature(test)]\n\nextern crate test;\n\n# fn main() {\n# struct X;\n# impl X { fn iter(&self, _: F) where F: FnMut() -> T {} } let b = X;\nb.iter(|| {\n let n = test::black_box(1000);\n\n (0..n).fold(0, |a, b| a ^ b)\n})\n# }\n```\n\nNeither of these read or modify the value, and are very cheap for small values.\nLarger values can be passed indirectly to reduce overhead (e.g.\n`black_box(&huge_struct)`).\n\nPerforming either of the above changes gives the following benchmarking results\n\n```text\nrunning 1 test\ntest bench_xor_1000_ints ... bench: 131 ns/iter (+/- 3)\n\ntest result: ok. 0 passed; 0 failed; 0 ignored; 1 measured\n```\n\nHowever, the optimizer can still modify a testcase in an undesirable manner\neven when using either of the above.\n" } , LintCompletion { label : "windows_stdio" , description : "# `windows_stdio`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "allocator_api" , description : "# `allocator_api`\n\nThe tracking issue for this feature is [#32838]\n\n[#32838]: https://github.com/rust-lang/rust/issues/32838\n\n------------------------\n\nSometimes you want the memory for one collection to use a different\nallocator than the memory for another collection.

Rust supports using inline\nassembly to do this via the `asm!` macro.\n\n# Guide-level explanation\n[guide-level-explanation]: #guide-level-explanation\n\nRust provides support for inline assembly via the `asm!` macro.\nIt can be used to embed handwritten assembly in the assembly output generated by the compiler.\nGenerally this should not be necessary, but might be where the required performance or timing\ncannot be otherwise achieved. Accessing low level hardware primitives, e.g. in kernel code, may also demand this functionality.\n\n> **Note**: the examples here are given in x86/x86-64 assembly, but ARM, AArch64 and RISC-V are also supported.\n\n## Basic usage\n\nLet us start with the simplest possible example:\n\n```rust,allow_fail\n# #![feature(asm)]\nunsafe {\n asm!(\"nop\");\n}\n```\n\nThis will insert a NOP (no operation) instruction into the assembly generated by the compiler.\nNote that all `asm!` invocations have to be inside an `unsafe` block, as they could insert\narbitrary instructions and break various invariants. The instructions to be inserted are listed\nin the first argument of the `asm!` macro as a string literal.\n\n## Inputs and outputs\n\nNow inserting an instruction that does nothing is rather boring. Let us do something that\nactually acts on data:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet x: u64;\nunsafe {\n asm!(\"mov {}, 5\", out(reg) x);\n}\nassert_eq!(x, 5);\n```\n\nThis will write the value `5` into the `u64` variable `x`.\nYou can see that the string literal we use to specify instructions is actually a template string.\nIt is governed by the same rules as Rust [format strings][format-syntax].\nThe arguments that are inserted into the template however look a bit different then you may\nbe familiar with. First we need to specify if the variable is an input or an output of the\ninline assembly. In this case it is an output. We declared this by writing `out`.\nWe also need to specify in what kind of register the assembly expects the variable.\nIn this case we put it in an arbitrary general purpose register by specifying `reg`.\nThe compiler will choose an appropriate register to insert into\nthe template and will read the variable from there after the inline assembly finishes executing.\n\nLet us see another example that also uses an input:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet i: u64 = 3;\nlet o: u64;\nunsafe {\n asm!(\n \"mov {0}, {1}\",\n \"add {0}, {number}\",\n out(reg) o,\n in(reg) i,\n number = const 5,\n );\n}\nassert_eq!(o, 8);\n```\n\nThis will add `5` to the input in variable `i` and write the result to variable `o`.\nThe particular way this assembly does this is first copying the value from `i` to the output,\nand then adding `5` to it.\n\nThe example shows a few things:\n\nFirst, we can see that `asm!` allows multiple template string arguments; each\none is treated as a separate line of assembly code, as if they were all joined\ntogether with newlines between them. This makes it easy to format assembly\ncode.\n\nSecond, we can see that inputs are declared by writing `in` instead of `out`.\n\nThird, one of our operands has a type we haven't seen yet, `const`.\nThis tells the compiler to expand this argument to value directly inside the assembly template.\nThis is only possible for constants and literals.\n\nFourth, we can see that we can specify an argument number, or name as in any format string.\nFor inline assembly templates this is particularly useful as arguments are often used more than once.\nFor more complex inline assembly using this facility is generally recommended, as it improves\nreadability, and allows reordering instructions without changing the argument order.\n\nWe can further refine the above example to avoid the `mov` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut x: u64 = 3;\nunsafe {\n asm!(\"add {0}, {number}\", inout(reg) x, number = const 5);\n}\nassert_eq!(x, 8);\n```\n\nWe can see that `inout` is used to specify an argument that is both input and output.\nThis is different from specifying an input and output separately in that it is guaranteed to assign both to the same register.\n\nIt is also possible to specify different variables for the input and output parts of an `inout` operand:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet x: u64 = 3;\nlet y: u64;\nunsafe {\n asm!(\"add {0}, {number}\", inout(reg) x => y, number = const 5);\n}\nassert_eq!(y, 8);\n```\n\n## Late output operands\n\nThe Rust compiler is conservative with its allocation of operands. It is assumed that an `out`\ncan be written at any time, and can therefore not share its location with any other argument.\nHowever, to guarantee optimal performance it is important to use as few registers as possible,\nso they won't have to be saved and reloaded around the inline assembly block.\nTo achieve this Rust provides a `lateout` specifier. This can be used on any output that is\nwritten only after all inputs have been consumed.\nThere is also a `inlateout` variant of this specifier.\n\nHere is an example where `inlateout` *cannot* be used:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nlet c: u64 = 4;\nunsafe {\n asm!(\n \"add {0}, {1}\",\n \"add {0}, {2}\",\n inout(reg) a,\n in(reg) b,\n in(reg) c,\n );\n}\nassert_eq!(a, 12);\n```\n\nHere the compiler is free to allocate the same register for inputs `b` and `c` since it knows they have the same value. However it must allocate a separate register for `a` since it uses `inout` and not `inlateout`. If `inlateout` was used, then `a` and `c` could be allocated to the same register, in which case the first instruction to overwrite the value of `c` and cause the assembly code to produce the wrong result.\n\nHowever the following example can use `inlateout` since the output is only modified after all input registers have been read:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nunsafe {\n asm!(\"add {0}, {1}\", inlateout(reg) a, in(reg) b);\n}\nassert_eq!(a, 8);\n```\n\nAs you can see, this assembly fragment will still work correctly if `a` and `b` are assigned to the same register.\n\n## Explicit register operands\n\nSome instructions require that the operands be in a specific register.\nTherefore, Rust inline assembly provides some more specific constraint specifiers.\nWhile `reg` is generally available on any architecture, these are highly architecture specific. E.g. for x86 the general purpose registers `eax`, `ebx`, `ecx`, `edx`, `ebp`, `esi`, and `edi`\namong others can be addressed by their name.\n\n```rust,allow_fail,no_run\n# #![feature(asm)]\nlet cmd = 0xd1;\nunsafe {\n asm!(\"out 0x64, eax\", in(\"eax\") cmd);\n}\n```\n\nIn this example we call the `out` instruction to output the content of the `cmd` variable\nto port `0x64`. Since the `out` instruction only accepts `eax` (and its sub registers) as operand\nwe had to use the `eax` constraint specifier.\n\nNote that unlike other operand types, explicit register operands cannot be used in the template string: you can't use `{}` and should write the register name directly instead. Also, they must appear at the end of the operand list after all other operand types.\n\nConsider this example which uses the x86 `mul` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nfn mul(a: u64, b: u64) -> u128 {\n let lo: u64;\n let hi: u64;\n\n unsafe {\n asm!(\n // The x86 mul instruction takes rax as an implicit input and writes\n // the 128-bit result of the multiplication to rax:rdx.\n \"mul {}\",\n in(reg) a,\n inlateout(\"rax\") b => lo,\n lateout(\"rdx\") hi\n );\n }\n\n ((hi as u128) << 64) + lo as u128\n}\n```\n\nThis uses the `mul` instruction to multiply two 64-bit inputs with a 128-bit result.\nThe only explicit operand is a register, that we fill from the variable `a`.\nThe second operand is implicit, and must be the `rax` register, which we fill from the variable `b`.\nThe lower 64 bits of the result are stored in `rax` from which we fill the variable `lo`.\nThe higher 64 bits are stored in `rdx` from which we fill the variable `hi`.\n\n## Clobbered registers\n\nIn many cases inline assembly will modify state that is not needed as an output.\nUsually this is either because we have to use a scratch register in the assembly,\nor instructions modify state that we don't need to further examine.\nThis state is generally referred to as being \"clobbered\".\nWe need to tell the compiler about this since it may need to save and restore this state\naround the inline assembly block.\n\n```rust,allow_fail\n# #![feature(asm)]\nlet ebx: u32;\nlet ecx: u32;\n\nunsafe {\n asm!(\n \"cpuid\",\n // EAX 4 selects the \"Deterministic Cache Parameters\" CPUID leaf\n inout(\"eax\") 4 => _,\n // ECX 0 selects the L0 cache information.\n inout(\"ecx\") 0 => ecx,\n lateout(\"ebx\") ebx,\n lateout(\"edx\") _,\n );\n}\n\nprintln!(\n \"L1 Cache: {}\",\n ((ebx >> 22) + 1) * (((ebx >> 12) & 0x3ff) + 1) * ((ebx & 0xfff) + 1) * (ecx + 1)\n);\n```\n\nIn the example above we use the `cpuid` instruction to get the L1 cache size.\nThis instruction writes to `eax`, `ebx`, `ecx`, and `edx`, but for the cache size we only care about the contents of `ebx` and `ecx`.\n\nHowever we still need to tell the compiler that `eax` and `edx` have been modified so that it can save any values that were in these registers before the asm. This is done by declaring these as outputs but with `_` instead of a variable name, which indicates that the output value is to be discarded.\n\nThis can also be used with a general register class (e.g. `reg`) to obtain a scratch register for use inside the asm code:\n\n```rust,allow_fail\n# #![feature(asm)]\n// Multiply x by 6 using shifts and adds\nlet mut x: u64 = 4;\nunsafe {\n asm!(\n \"mov {tmp}, {x}\",\n \"shl {tmp}, 1\",\n \"shl {x}, 2\",\n \"add {x}, {tmp}\",\n x = inout(reg) x,\n tmp = out(reg) _,\n );\n}\nassert_eq!(x, 4 * 6);\n```\n\n## Symbol operands\n\nA special operand type, `sym`, allows you to use the symbol name of a `fn` or `static` in inline assembly code.\nThis allows you to call a function or access a global variable without needing to keep its address in a register.\n\n```rust,allow_fail\n# #![feature(asm)]\nextern \"C\" fn foo(arg: i32) {\n println!(\"arg = {}\", arg);\n}\n\nfn call_foo(arg: i32) {\n unsafe {\n asm!(\n \"call {}\",\n sym foo,\n // 1st argument in rdi, which is caller-saved\n inout(\"rdi\") arg => _,\n // All caller-saved registers must be marked as clobberred\n out(\"rax\") _, out(\"rcx\") _, out(\"rdx\") _, out(\"rsi\") _,\n out(\"r8\") _, out(\"r9\") _, out(\"r10\") _, out(\"r11\") _,\n out(\"xmm0\") _, out(\"xmm1\") _, out(\"xmm2\") _, out(\"xmm3\") _,\n out(\"xmm4\") _, out(\"xmm5\") _, out(\"xmm6\") _, out(\"xmm7\") _,\n out(\"xmm8\") _, out(\"xmm9\") _, out(\"xmm10\") _, out(\"xmm11\") _,\n out(\"xmm12\") _, out(\"xmm13\") _, out(\"xmm14\") _, out(\"xmm15\") _,\n )\n }\n}\n```\n\nNote that the `fn` or `static` item does not need to be public or `#[no_mangle]`:\nthe compiler will automatically insert the appropriate mangled symbol name into the assembly code.\n\n## Register template modifiers\n\nIn some cases, fine control is needed over the way a register name is formatted when inserted into the template string. This is needed when an architecture's assembly language has several names for the same register, each typically being a \"view\" over a subset of the register (e.g. the low 32 bits of a 64-bit register).\n\nBy default the compiler will always choose the name that refers to the full register size (e.g. `rax` on x86-64, `eax` on x86, etc).\n\nThis default can be overriden by using modifiers on the template string operands, just like you would with format strings:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut x: u16 = 0xab;\n\nunsafe {\n asm!(\"mov {0:h}, {0:l}\", inout(reg_abcd) x);\n}\n\nassert_eq!(x, 0xabab);\n```\n\nIn this example, we use the `reg_abcd` register class to restrict the register allocator to the 4 legacy x86 register (`ax`, `bx`, `cx`, `dx`) of which the first two bytes can be addressed independently.\n\nLet us assume that the register allocator has chosen to allocate `x` in the `ax` register.\nThe `h` modifier will emit the register name for the high byte of that register and the `l` modifier will emit the register name for the low byte. The asm code will therefore be expanded as `mov ah, al` which copies the low byte of the value into the high byte.\n\nIf you use a smaller data type (e.g. `u16`) with an operand and forget the use template modifiers, the compiler will emit a warning and suggest the correct modifier to use.\n\n## Options\n\nBy default, an inline assembly block is treated the same way as an external FFI function call with a custom calling convention: it may read/write memory, have observable side effects, etc. However in many cases, it is desirable to give the compiler more information about what the assembly code is actually doing so that it can optimize better.\n\nLet's take our previous example of an `add` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nunsafe {\n asm!(\n \"add {0}, {1}\",\n inlateout(reg) a, in(reg) b,\n options(pure, nomem, nostack),\n );\n}\nassert_eq!(a, 8);\n```\n\nOptions can be provided as an optional final argument to the `asm!` macro. We specified three options here:\n- `pure` means that the asm code has no observable side effects and that its output depends only on its inputs. This allows the compiler optimizer to call the inline asm fewer times or even eliminate it entirely.\n- `nomem` means that the asm code does not read or write to memory. By default the compiler will assume that inline assembly can read or write any memory address that is accessible to it (e.g. through a pointer passed as an operand, or a global).\n- `nostack` means that the asm code does not push any data onto the stack. This allows the compiler to use optimizations such as the stack red zone on x86-64 to avoid stack pointer adjustments.\n\nThese allow the compiler to better optimize code using `asm!`, for example by eliminating pure `asm!` blocks whose outputs are not needed.\n\nSee the reference for the full list of available options and their effects.\n\n# Reference-level explanation\n[reference-level-explanation]: #reference-level-explanation\n\nInline assembler is implemented as an unsafe macro `asm!()`.\nThe first argument to this macro is a template string literal used to build the final assembly.\nThe following arguments specify input and output operands.\nWhen required, options are specified as the final argument.\n\nThe following ABNF specifies the general syntax:\n\n```ignore\ndir_spec := \"in\" / \"out\" / \"lateout\" / \"inout\" / \"inlateout\"\nreg_spec := / \"\"\noperand_expr := expr / \"_\" / expr \"=>\" expr / expr \"=>\" \"_\"\nreg_operand := dir_spec \"(\" reg_spec \")\" operand_expr\noperand := reg_operand / \"const\" const_expr / \"sym\" path\noption := \"pure\" / \"nomem\" / \"readonly\" / \"preserves_flags\" / \"noreturn\" / \"att_syntax\"\noptions := \"options(\" option *[\",\" option] [\",\"] \")\"\nasm := \"asm!(\" format_string *(\",\" format_string) *(\",\" [ident \"=\"] operand) [\",\" options] [\",\"] \")\"\n```\n\nThe macro will initially be supported only on ARM, AArch64, Hexagon, x86, x86-64 and RISC-V targets. Support for more targets may be added in the future. The compiler will emit an error if `asm!` is used on an unsupported target.\n\n[format-syntax]: https://doc.rust-lang.org/std/fmt/#syntax\n\n## Template string arguments\n\nThe assembler template uses the same syntax as [format strings][format-syntax] (i.e. placeholders are specified by curly braces). The corresponding arguments are accessed in order, by index, or by name. However, implicit named arguments (introduced by [RFC #2795][rfc-2795]) are not supported.\n\nAn `asm!` invocation may have one or more template string arguments; an `asm!` with multiple template string arguments is treated as if all the strings were concatenated with a `\\n` between them. The expected usage is for each template string argument to correspond to a line of assembly code. All template string arguments must appear before any other arguments.\n\nAs with format strings, named arguments must appear after positional arguments. Explicit register operands must appear at the end of the operand list, after named arguments if any.\n\nExplicit register operands cannot be used by placeholders in the template string. All other named and positional operands must appear at least once in the template string, otherwise a compiler error is generated.\n\nThe exact assembly code syntax is target-specific and opaque to the compiler except for the way operands are substituted into the template string to form the code passed to the assembler.\n\nThe 5 targets specified in this RFC (x86, ARM, AArch64, RISC-V, Hexagon) all use the assembly code syntax of the GNU assembler (GAS). On x86, the `.intel_syntax noprefix` mode of GAS is used by default. On ARM, the `.syntax unified` mode is used. These targets impose an additional restriction on the assembly code: any assembler state (e.g. the current section which can be changed with `.section`) must be restored to its original value at the end of the asm string. Assembly code that does not conform to the GAS syntax will result in assembler-specific behavior.\n\n[rfc-2795]: https://github.com/rust-lang/rfcs/pull/2795\n\n## Operand type\n\nSeveral types of operands are supported:\n\n* `in() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain the value of `` at the start of the asm code.\n - The allocated register must contain the same value at the end of the asm code (except if a `lateout` is allocated to the same register).\n* `out() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain an undefined value at the start of the asm code.\n - `` must be a (possibly uninitialized) place expression, to which the contents of the allocated register is written to at the end of the asm code.\n - An underscore (`_`) may be specified instead of an expression, which will cause the contents of the register to be discarded at the end of the asm code (effectively acting as a clobber).\n* `lateout() `\n - Identical to `out` except that the register allocator can reuse a register allocated to an `in`.\n - You should only write to the register after all inputs are read, otherwise you may clobber an input.\n* `inout() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain the value of `` at the start of the asm code.\n - `` must be a mutable initialized place expression, to which the contents of the allocated register is written to at the end of the asm code.\n* `inout() => `\n - Same as `inout` except that the initial value of the register is taken from the value of ``.\n - `` must be a (possibly uninitialized) place expression, to which the contents of the allocated register is written to at the end of the asm code.\n - An underscore (`_`) may be specified instead of an expression for ``, which will cause the contents of the register to be discarded at the end of the asm code (effectively acting as a clobber).\n - `` and `` may have different types.\n* `inlateout() ` / `inlateout() => `\n - Identical to `inout` except that the register allocator can reuse a register allocated to an `in` (this can happen if the compiler knows the `in` has the same initial value as the `inlateout`).\n - You should only write to the register after all inputs are read, otherwise you may clobber an input.\n* `const `\n - `` must be an integer or floating-point constant expression.\n - The value of the expression is formatted as a string and substituted directly into the asm template string.\n* `sym `\n - `` must refer to a `fn` or `static`.\n - A mangled symbol name referring to the item is substituted into the asm template string.\n - The substituted string does not include any modifiers (e.g. GOT, PLT, relocations, etc).\n - `` is allowed to point to a `#[thread_local]` static, in which case the asm code can combine the symbol with relocations (e.g. `@plt`, `@TPOFF`) to read from thread-local data.\n\nOperand expressions are evaluated from left to right, just like function call arguments. After the `asm!` has executed, outputs are written to in left to right order. This is significant if two outputs point to the same place: that place will contain the value of the rightmost output.\n\n## Register operands\n\nInput and output operands can be specified either as an explicit register or as a register class from which the register allocator can select a register. Explicit registers are specified as string literals (e.g. `\"eax\"`) while register classes are specified as identifiers (e.g. `reg`). Using string literals for register names enables support for architectures that use special characters in register names, such as MIPS (`$0`, `$1`, etc).\n\nNote that explicit registers treat register aliases (e.g. `r14` vs `lr` on ARM) and smaller views of a register (e.g. `eax` vs `rax`) as equivalent to the base register. It is a compile-time error to use the same explicit register for two input operands or two output operands. Additionally, it is also a compile-time error to use overlapping registers (e.g. ARM VFP) in input operands or in output operands.\n\nOnly the following types are allowed as operands for inline assembly:\n- Integers (signed and unsigned)\n- Floating-point numbers\n- Pointers (thin only)\n- Function pointers\n- SIMD vectors (structs defined with `#[repr(simd)]` and which implement `Copy`). This includes architecture-specific vector types defined in `std::arch` such as `__m128` (x86) or `int8x16_t` (ARM).\n\nHere is the list of currently supported register classes:\n\n| Architecture | Register class | Registers | LLVM constraint code |\n| ------------ | -------------- | --------- | -------------------- |\n| x86 | `reg` | `ax`, `bx`, `cx`, `dx`, `si`, `di`, `r[8-15]` (x86-64 only) | `r` |\n| x86 | `reg_abcd` | `ax`, `bx`, `cx`, `dx` | `Q` |\n| x86-32 | `reg_byte` | `al`, `bl`, `cl`, `dl`, `ah`, `bh`, `ch`, `dh` | `q` |\n| x86-64 | `reg_byte` | `al`, `bl`, `cl`, `dl`, `sil`, `dil`, `r[8-15]b`, `ah`\\*, `bh`\\*, `ch`\\*, `dh`\\* | `q` |\n| x86 | `xmm_reg` | `xmm[0-7]` (x86) `xmm[0-15]` (x86-64) | `x` |\n| x86 | `ymm_reg` | `ymm[0-7]` (x86) `ymm[0-15]` (x86-64) | `x` |\n| x86 | `zmm_reg` | `zmm[0-7]` (x86) `zmm[0-31]` (x86-64) | `v` |\n| x86 | `kreg` | `k[1-7]` | `Yk` |\n| AArch64 | `reg` | `x[0-28]`, `x30` | `r` |\n| AArch64 | `vreg` | `v[0-31]` | `w` |\n| AArch64 | `vreg_low16` | `v[0-15]` | `x` |\n| ARM | `reg` | `r[0-5]` `r7`\\*, `r[8-10]`, `r11`\\*, `r12`, `r14` | `r` |\n| ARM (Thumb) | `reg_thumb` | `r[0-r7]` | `l` |\n| ARM (ARM) | `reg_thumb` | `r[0-r10]`, `r12`, `r14` | `l` |\n| ARM | `sreg` | `s[0-31]` | `t` |\n| ARM | `sreg_low16` | `s[0-15]` | `x` |\n| ARM | `dreg` | `d[0-31]` | `w` |\n| ARM | `dreg_low16` | `d[0-15]` | `t` |\n| ARM | `dreg_low8` | `d[0-8]` | `x` |\n| ARM | `qreg` | `q[0-15]` | `w` |\n| ARM | `qreg_low8` | `q[0-7]` | `t` |\n| ARM | `qreg_low4` | `q[0-3]` | `x` |\n| NVPTX | `reg16` | None\\* | `h` |\n| NVPTX | `reg32` | None\\* | `r` |\n| NVPTX | `reg64` | None\\* | `l` |\n| RISC-V | `reg` | `x1`, `x[5-7]`, `x[9-15]`, `x[16-31]` (non-RV32E) | `r` |\n| RISC-V | `freg` | `f[0-31]` | `f` |\n| Hexagon | `reg` | `r[0-28]` | `r` |\n\n> **Note**: On x86 we treat `reg_byte` differently from `reg` because the compiler can allocate `al` and `ah` separately whereas `reg` reserves the whole register.\n>\n> Note #2: On x86-64 the high byte registers (e.g. `ah`) are only available when used as an explicit register. Specifying the `reg_byte` register class for an operand will always allocate a low byte register.\n>\n> Note #3: NVPTX doesn't have a fixed register set, so named registers are not supported.\n>\n> Note #4: On ARM the frame pointer is either `r7` or `r11` depending on the platform.\n\nAdditional register classes may be added in the future based on demand (e.g. MMX, x87, etc).\n\nEach register class has constraints on which value types they can be used with. This is necessary because the way a value is loaded into a register depends on its type. For example, on big-endian systems, loading a `i32x4` and a `i8x16` into a SIMD register may result in different register contents even if the byte-wise memory representation of both values is identical. The availability of supported types for a particular register class may depend on what target features are currently enabled.\n\n| Architecture | Register class | Target feature | Allowed types |\n| ------------ | -------------- | -------------- | ------------- |\n| x86-32 | `reg` | None | `i16`, `i32`, `f32` |\n| x86-64 | `reg` | None | `i16`, `i32`, `f32`, `i64`, `f64` |\n| x86 | `reg_byte` | None | `i8` |\n| x86 | `xmm_reg` | `sse` | `i32`, `f32`, `i64`, `f64`,

The only exception is the `freg` register class on RISC-V where `f32` values are NaN-boxed in a `f64` as required by the RISC-V architecture.\n\nWhen separate input and output expressions are specified for an `inout` operand, both expressions must have the same type. The only exception is if both operands are pointers or integers, in which case they are only required to have the same size. This restriction exists because the register allocators in LLVM and GCC sometimes cannot handle tied operands with different types.\n\n## Register names\n\nSome registers have multiple names.

The frame pointer cannot be used as an input or output. |\n| ARM | `r6` | `r6` is used internally by LLVM as a base pointer and therefore cannot be used as an input or output. |\n| x86 | `k0` | This is a constant zero register which can't be modified. |\n| x86 | `ip` | This is the program counter, not a real register. |\n| x86 | `mm[0-7]` | MMX registers are not currently supported (but may be in the future). |\n| x86 | `st([0-7])` | x87 registers are not currently supported (but may be in the future). |\n| AArch64 | `xzr` | This is a constant zero register which can't be modified. |\n| ARM | `pc` | This is the program counter, not a real register. |\n| RISC-V | `x0` | This is a constant zero register which can't be modified. |\n| RISC-V | `gp`, `tp` | These registers are reserved and cannot be used as inputs or outputs. |\n| Hexagon | `lr` | This is the link register which cannot be used as an input or output. |\n\n## Template modifiers\n\nThe placeholders can be augmented by modifiers which are specified after the `:` in the curly braces. These modifiers do not affect register allocation, but change the way operands are formatted when inserted into the template string. Only one modifier is allowed per template placeholder.\n\nThe supported modifiers are a subset of LLVM's (and GCC's) [asm template argument modifiers][llvm-argmod], but do not use the same letter codes.\n\n| Architecture | Register class | Modifier | Example output | LLVM modifier |\n| ------------ | -------------- | -------- | -------------- | ------------- |\n| x86-32 | `reg` | None | `eax` | `k` |\n| x86-64 | `reg` | None | `rax` | `q` |\n| x86-32 | `reg_abcd` | `l` | `al` | `b` |\n| x86-64 | `reg` | `l` | `al` | `b` |\n| x86 | `reg_abcd` | `h` | `ah` | `h` |\n| x86 | `reg` | `x` | `ax` | `w` |\n| x86 | `reg` | `e` | `eax` | `k` |\n| x86-64 | `reg` | `r` | `rax` | `q` |\n| x86 | `reg_byte` | None | `al` / `ah` | None |\n| x86 | `xmm_reg` | None | `xmm0` | `x` |\n| x86 | `ymm_reg` | None | `ymm0` | `t` |\n| x86 | `zmm_reg` | None | `zmm0` | `g` |\n| x86 | `*mm_reg` | `x` | `xmm0` | `x` |\n| x86 | `*mm_reg` | `y` | `ymm0` | `t` |\n| x86 | `*mm_reg` | `z` | `zmm0` | `g` |\n| x86 | `kreg` | None | `k1` | None |\n| AArch64 | `reg` | None | `x0` | `x` |\n| AArch64 | `reg` | `w` | `w0` | `w` |\n| AArch64 | `reg` | `x` | `x0` | `x` |\n| AArch64 | `vreg` | None | `v0` | None |\n| AArch64 | `vreg` | `v` | `v0` | None |\n| AArch64 | `vreg` | `b` | `b0` | `b` |\n| AArch64 | `vreg` | `h` | `h0` | `h` |\n| AArch64 | `vreg` | `s` | `s0` | `s` |\n| AArch64 | `vreg` | `d` | `d0` | `d` |\n| AArch64 | `vreg` | `q` | `q0` | `q` |\n| ARM | `reg` | None | `r0` | None |\n| ARM | `sreg` | None | `s0` | None |\n| ARM | `dreg` | None | `d0` | `P` |\n| ARM | `qreg` | None | `q0` | `q` |\n| ARM | `qreg` | `e` / `f` | `d0` / `d1` | `e` / `f` |\n| NVPTX | `reg16` | None | `rs0` | None |\n| NVPTX | `reg32` | None | `r0` | None |\n| NVPTX | `reg64` | None | `rd0` | None |\n| RISC-V | `reg` | None | `x1` | None |\n| RISC-V | `freg` | None | `f0` | None |\n| Hexagon | `reg` | None | `r0` | None |\n\n> Notes:\n> - on ARM `e` / `f`: this prints the low or high doubleword register name of a NEON quad (128-bit) register.\n> - on x86: our behavior for `reg` with no modifiers differs from what GCC does. GCC will infer the modifier based on the operand value type, while we default to the full register size.\n> - on x86 `xmm_reg`: the `x`, `t` and `g` LLVM modifiers are not yet implemented in LLVM (they are supported by GCC only), but this should be a simple change.\n\nAs stated in the previous section, passing an input value smaller than the register width will result in the upper bits of the register containing undefined values. This is not a problem if the inline asm only accesses the lower bits of the register, which can be done by using a template modifier to use a subregister name in the asm code (e.g. `ax` instead of `rax`). Since this an easy pitfall, the compiler will suggest a template modifier to use where appropriate given the input type. If all references to an operand already have modifiers then the warning is suppressed for that operand.\n\n[llvm-argmod]: http://llvm.org/docs/LangRef.html#asm-template-argument-modifiers\n\n## Options\n\nFlags are used to further influence the behavior of the inline assembly block.\nCurrently the following options are defined:\n- `pure`: The `asm` block has no side effects, and its outputs depend only on its direct inputs (i.e. the values themselves, not what they point to) or values read from memory (unless the `nomem` options is also set). This allows the compiler to execute the `asm` block fewer times than specified in the program (e.g. by hoisting it out of a loop) or even eliminate it entirely if the outputs are not used.\n- `nomem`: The `asm` blocks does not read or write to any memory. This allows the compiler to cache the values of modified global variables in registers across the `asm` block since it knows that they are not read or written to by the `asm`.\n- `readonly`: The `asm` block does not write to any memory. This allows the compiler to cache the values of unmodified global variables in registers across the `asm` block since it knows that they are not written to by the `asm`.\n- `preserves_flags`: The `asm` block does not modify the flags register (defined in the rules below). This allows the compiler to avoid recomputing the condition flags after the `asm` block.\n- `noreturn`: The `asm` block never returns, and its return type is defined as `!` (never). Behavior is undefined if execution falls through past the end of the asm code. A `noreturn` asm block behaves just like a function which doesn't return; notably, local variables in scope are not dropped before it is invoked.\n- `nostack`: The `asm` block does not push data to the stack, or write to the stack red-zone (if supported by the target). If this option is *not* used then the stack pointer is guaranteed to be suitably aligned (according to the target ABI) for a function call.\n- `att_syntax`: This option is only valid on x86, and causes the assembler to use the `.att_syntax prefix` mode of the GNU assembler. Register operands are substituted in with a leading `%`.\n\nThe compiler performs some additional checks on options:\n- The `nomem` and `readonly` options are mutually exclusive: it is a compile-time error to specify both.\n- The `pure` option must be combined with either the `nomem` or `readonly` options, otherwise a compile-time error is emitted.\n- It is a compile-time error to specify `pure` on an asm block with no outputs or only discarded outputs (`_`).\n- It is a compile-time error to specify `noreturn` on an asm block with outputs.\n\n## Rules for inline assembly\n\n- Any registers not specified as inputs will contain an undefined value on entry to the asm block.\n - An \"undefined value\" in the context of inline assembly means that the register can (non-deterministically) have any one of the possible values allowed by the architecture. Notably it is not the same as an LLVM `undef` which can have a different value every time you read it (since such a concept does not exist in assembly code).\n- Any registers not specified as outputs must have the same value upon exiting the asm block as they had on entry, otherwise behavior is undefined.\n - This only applies to registers which can be specified as an input or output. Other registers follow target-specific rules.\n - Note that a `lateout` may be allocated to the same register as an `in`, in which case this rule does not apply. Code should not rely on this however since it depends on the results of register allocation.\n- Behavior is undefined if execution unwinds out of an asm block.\n - This also applies if the assembly code calls a function which then unwinds.\n- The set of memory locations that assembly code is allowed the read and write are the same as those allowed for an FFI function.\n - Refer to the unsafe code guidelines for the exact rules.\n - If the `readonly` option is set, then only memory reads are allowed.\n - If the `nomem` option is set then no reads or writes to memory are allowed.\n - These rules do not apply to memory which is private to the asm code, such as stack space allocated within the asm block.\n- The compiler cannot assume that the instructions in the asm are the ones that will actually end up executed.\n - This effectively means that the compiler must treat the `asm!` as a black box and only take the interface specification into account, not the instructions themselves.\n - Runtime code patching is allowed, via target-specific mechanisms (outside the scope of this RFC).\n- Unless the `nostack` option is set, asm code is allowed to use stack space below the stack pointer.\n - On entry to the asm block the stack pointer is guaranteed to be suitably aligned (according to the target ABI) for a function call.\n - You are responsible for making sure you don't overflow the stack (e.g. use stack probing to ensure you hit a guard page).\n - You should adjust the stack pointer when allocating stack memory as required by the target ABI.\n - The stack pointer must be restored to its original value before leaving the asm block.\n- If the `noreturn` option is set then behavior is undefined if execution falls through to the end of the asm block.\n- If the `pure` option is set then behavior is undefined if the `asm` has side-effects other than its direct outputs. Behavior is also undefined if two executions of the `asm` code with the same inputs result in different outputs.\n - When used with the `nomem` option, \"inputs\" are just the direct inputs of the `asm!`.\n - When used with the `readonly` option, \"inputs\" comprise the direct inputs of the `asm!` and any memory that the `asm!` block is allowed to read.\n- These flags registers must be restored upon exiting the asm block if the `preserves_flags` option is set:\n - x86\n - Status flags in `EFLAGS` (CF, PF, AF, ZF, SF, OF).\n - Floating-point status word (all).\n - Floating-point exception flags in `MXCSR` (PE, UE, OE, ZE, DE, IE).\n - ARM\n - Condition flags in `CPSR` (N, Z, C, V)\n - Saturation flag in `CPSR` (Q)\n - Greater than or equal flags in `CPSR` (GE).\n - Condition flags in `FPSCR` (N, Z, C, V)\n - Saturation flag in `FPSCR` (QC)\n - Floating-point exception flags in `FPSCR` (IDC, IXC, UFC, OFC, DZC, IOC).\n - AArch64\n - Condition flags (`NZCV` register).\n - Floating-point status (`FPSR` register).\n - RISC-V\n - Floating-point exception flags in `fcsr` (`fflags`).\n- On x86, the direction flag (DF in `EFLAGS`) is clear on entry to an asm block and must be clear on exit.\n - Behavior is undefined if the direction flag is set on exiting an asm block.\n- The requirement of restoring the stack pointer and non-output registers to their original value only applies when exiting an `asm!` block.\n - This means that `asm!` blocks that never return (even if not marked `noreturn`) don't need to preserve these registers.\n - When returning to a different `asm!` block than you entered (e.g. for context switching), these registers must contain the value they had upon entering the `asm!` block that you are *exiting*.\n - You cannot exit an `asm!` block that has not been entered. Neither can you exit an `asm!` block that has already been exited.\n - You are responsible for switching any target-specific state (e.g. thread-local storage, stack bounds).\n - The set of memory locations that you may access is the intersection of those allowed by the `asm!` blocks you entered and exited.\n- You cannot assume that an `asm!` block will appear exactly once in the output binary. The compiler is allowed to instantiate multiple copies of the `asm!` block, for example when the function containing it is inlined in multiple places.\n - As a consequence, you should only use [local labels] inside inline assembly code. Defining symbols in assembly code may lead to assembler and/or linker errors due to duplicate symbol definitions.\n\n> **Note**: As a general rule, the flags covered by `preserves_flags` are those which are *not* preserved when performing a function call.\n\n[local labels]: https://sourceware.org/binutils/docs/as/Symbol-Names.html#Local-Labels\n" } , LintCompletion { label : "is_sorted" ,

This is useful for very low level programming, where\nwhich register you use is important:\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# unsafe fn read_byte_in(port: u16) -> u8 {\nlet result: u8;\nllvm_asm!(\"in %dx, %al\" : \"={al}\"(result) : \"{dx}\"(port));\nresult\n# }\n```\n\n## Clobbers\n\nSome instructions modify registers which might otherwise have held\ndifferent values so we use the clobbers list to indicate to the\ncompiler not to assume any values loaded into those registers will\nstay valid.\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# fn main() { unsafe {\n// Put the value 0x200 in eax:\nllvm_asm!(\"mov $$0x200, %eax\" : /* no outputs */ : /* no inputs */ : \"eax\");\n# } }\n# #[cfg(not(any(target_arch = \"x86\", target_arch = \"x86_64\")))]\n# fn main() {}\n```\n\nInput and output registers need not be listed since that information\nis already communicated by the given constraints. Otherwise, any other\nregisters used either implicitly or explicitly should be listed.\n\nIf the assembly changes the condition code register `cc` should be\nspecified as one of the clobbers. Similarly, if the assembly modifies\nmemory, `memory` should also be specified.\n\n## Options\n\nThe last section, `options` is specific to Rust. The format is comma\nseparated literal strings (i.e. `:\"foo\", \"bar\", \"baz\"`). It's used to\nspecify some extra info about the inline assembly:\n\nCurrent valid options are:\n\n1. *volatile* - specifying this is analogous to\n `__asm__ __volatile__ (...)` in gcc/clang.\n2. *alignstack* - certain instructions expect the stack to be\n aligned a certain way (i.e. SSE) and specifying this indicates to\n the compiler to insert its usual stack alignment code\n3. *intel* - use intel syntax instead of the default AT&T.\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# fn main() {\nlet result: i32;\nunsafe {\n llvm_asm!(\"mov eax, 2\" : \"={eax}\"(result) : : : \"intel\")\n}\nprintln!(\"eax is currently {}\", result);\n# }\n# #[cfg(not(any(target_arch = \"x86\", target_arch = \"x86_64\")))]\n# fn main() {}\n```\n\n## More Information\n\nThe current implementation of the `llvm_asm!` macro is a direct binding to [LLVM's\ninline assembler expressions][llvm-docs], so be sure to check out [their\ndocumentation as well][llvm-docs] for more information about clobbers,\nconstraints, etc.\n\n[llvm-docs]: http://llvm.org/docs/LangRef.html#inline-assembler-expressions\n\nIf you need more power and don't mind losing some of the niceties of\n`llvm_asm!`, check out [global_asm](global-asm.md).\n" } ] ; diff --git a/xtask/src/codegen.rs b/xtask/src/codegen.rs index f5f4b964a4..209caacc3d 100644 --- a/xtask/src/codegen.rs +++ b/xtask/src/codegen.rs @@ -9,6 +9,7 @@ mod gen_syntax; mod gen_parser_tests; mod gen_assists_docs; mod gen_feature_docs; +mod gen_unstable_future_descriptor; use std::{ fmt, mem, @@ -22,8 +23,12 @@ pub use self::{ gen_feature_docs::generate_feature_docs, gen_parser_tests::generate_parser_tests, gen_syntax::generate_syntax, + gen_unstable_future_descriptor::generate_unstable_future_descriptor, }; +// Directory used by xtask +const STORAGE: &str = ".xtask"; + const GRAMMAR_DIR: &str = "crates/ra_parser/src/grammar"; const OK_INLINE_TESTS_DIR: &str = "crates/ra_syntax/test_data/parser/inline/ok"; const ERR_INLINE_TESTS_DIR: &str = "crates/ra_syntax/test_data/parser/inline/err"; @@ -35,6 +40,9 @@ const AST_TOKENS: &str = "crates/ra_syntax/src/ast/generated/tokens.rs"; const ASSISTS_DIR: &str = "crates/ra_assists/src/handlers"; const ASSISTS_TESTS: &str = "crates/ra_assists/src/tests/generated.rs"; +const REPOSITORY_URL: &str = "https://github.com/rust-lang/rust"; +const UNSTABLE_FEATURE: &str = "crates/ra_ide/src/completion/unstable_feature_descriptor.rs"; + #[derive(Debug, PartialEq, Eq, Clone, Copy)] pub enum Mode { Overwrite, diff --git a/xtask/src/codegen/gen_unstable_future_descriptor.rs b/xtask/src/codegen/gen_unstable_future_descriptor.rs new file mode 100644 index 0000000000..09c4f61f2e --- /dev/null +++ b/xtask/src/codegen/gen_unstable_future_descriptor.rs @@ -0,0 +1,55 @@ +//!

A generator is a \"resumable function\" that syntactically\nresembles a closure but compiles to much different semantics in the compiler\nitself. The primary feature of a generator is that it can be suspended during\nexecution to be resumed at a later date. Generators use the `yield` keyword to\n\"return\", and then the caller can `resume` a generator to resume execution just\nafter the `yield` keyword.\n\nGenerators are an extra-unstable feature in the compiler right now. Added in\n[RFC 2033] they're mostly intended right now as a information/constraint\ngathering phase. The intent is that experimentation can happen on the nightly\ncompiler before actual stabilization. A further RFC will be required to\nstabilize generators/coroutines and will likely contain at least a few small\ntweaks to the overall design.\n\n[RFC 2033]: https://github.com/rust-lang/rfcs/pull/2033\n\nA syntactical example of a generator is:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::{Generator, GeneratorState};\nuse std::pin::Pin;\n\nfn main() {\n let mut generator = || {\n yield 1;\n return \"foo\"\n };\n\n match Pin::new(&mut generator).resume(()) {\n GeneratorState::Yielded(1) => {}\n _ => panic!(\"unexpected value from resume\"),\n }\n match Pin::new(&mut generator).resume(()) {\n GeneratorState::Complete(\"foo\") => {}\n _ => panic!(\"unexpected value from resume\"),\n }\n}\n```\n\nGenerators are closure-like literals which can contain a `yield` statement. The\n`yield` statement takes an optional expression of a value to yield out of the\ngenerator. All generator literals implement the `Generator` trait in the\n`std::ops` module. The `Generator` trait has one main method, `resume`, which\nresumes execution of the generator at the previous suspension point.\n\nAn example of the control flow of generators is that the following example\nprints all numbers in order:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::Generator;\nuse std::pin::Pin;\n\nfn main() {\n let mut generator = || {\n println!(\"2\");\n yield;\n println!(\"4\");\n };\n\n println!(\"1\");\n Pin::new(&mut generator).resume(());\n println!(\"3\");\n Pin::new(&mut generator).resume(());\n println!(\"5\");\n}\n```\n\nAt this time the main intended use case of generators is an implementation\nprimitive for async/await syntax, but generators will likely be extended to\nergonomic implementations of iterators and other primitives in the future.\nFeedback on the design and usage is always appreciated!\n\n### The `Generator` trait\n\nThe `Generator` trait in `std::ops` currently looks like:\n\n```rust\n# #![feature(arbitrary_self_types, generator_trait)]\n# use std::ops::GeneratorState;\n# use std::pin::Pin;\n\npub trait Generator {\n type Yield;\n type Return;\n fn resume(self: Pin<&mut Self>, resume: R) -> GeneratorState;\n}\n```\n\nThe `Generator::Yield` type is the type of values that can be yielded with the\n`yield` statement. The `Generator::Return` type is the returned type of the\ngenerator. This is typically the last expression in a generator's definition or\nany value passed to `return` in a generator. The `resume` function is the entry\npoint for executing the `Generator` itself.\n\nThe return value of `resume`, `GeneratorState`, looks like:\n\n```rust\npub enum GeneratorState {\n Yielded(Y),\n Complete(R),\n}\n```\n\nThe `Yielded` variant indicates that the generator can later be resumed. This\ncorresponds to a `yield` point in a generator. The `Complete` variant indicates\nthat the generator is complete and cannot be resumed again. Calling `resume`\nafter a generator has returned `Complete` will likely result in a panic of the\nprogram.\n\n### Closure-like semantics\n\nThe closure-like syntax for generators alludes to the fact that they also have\nclosure-like semantics. Namely:\n\n* When created, a generator executes no code. A closure literal does not\n actually execute any of the closure's code on construction, and similarly a\n generator literal does not execute any code inside the generator when\n constructed.\n\n* Generators can capture outer variables by reference or by move, and this can\n be tweaked with the `move` keyword at the beginning of the closure. Like\n closures all generators will have an implicit environment which is inferred by\n the compiler. Outer variables can be moved into a generator for use as the\n generator progresses.\n\n* Generator literals produce a value with a unique type which implements the\n `std::ops::Generator` trait. This allows actual execution of the generator\n through the `Generator::resume` method as well as also naming it in return\n types and such.\n\n* Traits like `Send` and `Sync` are automatically implemented for a `Generator`\n depending on the captured variables of the environment. Unlike closures,\n generators also depend on variables live across suspension points. This means\n that although the ambient environment may be `Send` or `Sync`, the generator\n itself may not be due to internal variables live across `yield` points being\n not-`Send` or not-`Sync`. Note that generators do\n not implement traits like `Copy` or `Clone` automatically.\n\n* Whenever a generator is dropped it will drop all captured environment\n variables.\n\n### Generators as state machines\n\nIn the compiler, generators are currently compiled as state machines. Each\n`yield` expression will correspond to a different state that stores all live\nvariables over that suspension point. Resumption of a generator will dispatch on\nthe current state and then execute internally until a `yield` is reached, at\nwhich point all state is saved off in the generator and a value is returned.\n\nLet's take a look at an example to see what's going on here:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::Generator;\nuse std::pin::Pin;\n\nfn main() {\n let ret = \"foo\";\n let mut generator = move || {\n yield 1;\n return ret\n };\n\n Pin::new(&mut generator).resume(());\n Pin::new(&mut generator).resume(());\n}\n```\n\nThis generator literal will compile down to something similar to:\n\n```rust\n#![feature(arbitrary_self_types, generators, generator_trait)]\n\nuse std::ops::{Generator, GeneratorState};\nuse std::pin::Pin;\n\nfn main() {\n let ret = \"foo\";\n let mut generator = {\n enum __Generator {\n Start(&'static str),\n Yield1(&'static str),\n Done,\n }\n\n impl Generator for __Generator {\n type Yield = i32;\n type Return = &'static str;\n\n fn resume(mut self: Pin<&mut Self>, resume: ()) -> GeneratorState {\n use std::mem;\n match mem::replace(&mut *self, __Generator::Done) {\n __Generator::Start(s) => {\n *self = __Generator::Yield1(s);\n GeneratorState::Yielded(1)\n }\n\n __Generator::Yield1(s) => {\n *self = __Generator::Done;\n GeneratorState::Complete(s)\n }\n\n __Generator::Done => {\n panic!(\"generator resumed after completion\")\n }\n }\n }\n }\n\n __Generator::Start(ret)\n };\n\n Pin::new(&mut generator).resume(());\n Pin::new(&mut generator).resume(());\n}\n```\n\nNotably here we can see that the compiler is generating a fresh type,\n`__Generator` in this case. This type has a number of states (represented here\nas an `enum`) corresponding to each of the conceptual states of the generator.\nAt the beginning we're closing over our outer variable `foo` and then that\nvariable is also live over the `yield` point, so it's stored in both states.\n\nWhen the generator starts it'll immediately yield 1, but it saves off its state\njust before it does so indicating that it has reached the yield point. Upon\nresuming again we'll execute the `return ret` which returns the `Complete`\nstate.\n\nHere we can also note that the `Done` state, if resumed, panics immediately as\nit's invalid to resume a completed generator. It's also worth noting that this\nis just a rough desugaring, not a normative specification for what the compiler\ndoes.\n" } , LintCompletion { label : "marker_trait_attr" , description : "# `marker_trait_attr`\n\nThe tracking issue for this feature is: [#29864]\n\n[#29864]: https://github.com/rust-lang/rust/issues/29864\n\n------------------------\n\nNormally, Rust keeps you from adding trait implementations that could\noverlap with each other, as it would be ambiguous which to use.

In the syntax, `n` isn't necessarily a constant expression. The array is dynamically allocated on the stack and has the type of `[T]`, instead of `[T; n]`.\n\n```rust,ignore\n#![feature(unsized_locals)]\n\nfn mergesort(a: &mut [T]) {\n let mut tmp = [T; dyn a.len()];\n // ...\n}\n\nfn main() {\n let mut a = [3, 1, 5, 6];\n mergesort(&mut a);\n assert_eq!(a, [1, 3, 5, 6]);\n}\n```\n\nVLAs are not implemented yet. The syntax isn't final, either. We may need an alternative syntax for Rust 2015 because, in Rust 2015, expressions like `[e; dyn(1)]` would be ambiguous. One possible alternative proposed in the RFC is `[e; n]`: if `n` captures one or more local variables, then it is considered as `[e; dyn n]`.\n\n## Advisory on stack usage\n\nIt's advised not to casually use the `#![feature(unsized_locals)]` feature. Typical use-cases are:\n\n- When you need a by-value trait objects.\n- When you really need a fast allocation of small temporary arrays.\n\nAnother pitfall is repetitive allocation and temporaries. Currently the compiler simply extends the stack frame every time it encounters an unsized assignment. So for example, the code\n\n```rust\n#![feature(unsized_locals)]\n\nfn main() {\n let x: Box<[i32]> = Box::new([1, 2, 3, 4, 5]);\n let _x = {{{{{{{{{{*x}}}}}}}}}};\n}\n```\n\nand the code\n\n```rust\n#![feature(unsized_locals)]\n\nfn main() {\n for _ in 0..10 {\n let x: Box<[i32]> = Box::new([1, 2, 3, 4, 5]);\n let _x = *x;\n }\n}\n```\n\nwill unnecessarily extend the stack frame.\n" } , LintCompletion { label : "or_patterns" , description : "# `or_patterns`\n\nThe tracking issue for this feature is: [#54883]\n\n[#54883]: https://github.com/rust-lang/rust/issues/54883\n\n------------------------\n\nThe `or_pattern` language feature allows `|` to be arbitrarily nested within\na pattern, for example, `Some(A(0) | B(1 | 2))` becomes a valid pattern.\n\n## Examples\n\n```rust,ignore\n#![feature(or_patterns)]\n\npub enum Foo {\n Bar,\n Baz,\n Quux,\n}\n\npub fn example(maybe_foo: Option) {\n match maybe_foo {\n Some(Foo::Bar | Foo::Baz) => {\n println!(\"The value contained `Bar` or `Baz`\");\n }\n Some(_) => {\n println!(\"The value did not contain `Bar` or `Baz`\");\n }\n None => {\n println!(\"The value was `None`\");\n }\n }\n}\n```\n" } , LintCompletion { label : "member_constraints" , description : "# `member_constraints`\n\nThe tracking issue for this feature is: [#61997]\n\n[#61997]: https://github.com/rust-lang/rust/issues/61997\n\n------------------------\n\nThe `member_constraints` feature gate lets you use `impl Trait` syntax with\nmultiple unrelated lifetime parameters.\n\nA simple example is:\n\n```rust\n#![feature(member_constraints)]\n\ntrait Trait<'a, 'b> { }\nimpl Trait<'_, '_> for T {}\n\nfn foo<'a, 'b>(x: &'a u32, y: &'b u32) -> impl Trait<'a, 'b> {\n (x, y)\n}\n\nfn main() { }\n```\n\nWithout the `member_constraints` feature gate, the above example is an\nerror because both `'a` and `'b` appear in the impl Trait bounds, but\nneither outlives the other.\n" } , LintCompletion { label : "optin_builtin_traits" , description : "# `optin_builtin_traits`\n\nThe tracking issue for this feature is [#13231] \n\n[#13231]: https://github.com/rust-lang/rust/issues/13231\n\n----\n\nThe `optin_builtin_traits` feature gate allows you to define auto traits.\n\nAuto traits, like [`Send`] or [`Sync`] in the standard library, are marker traits\nthat are automatically implemented for every type, unless the type, or a type it contains, \nhas explicitly opted out via a negative impl. (Negative impls are separately controlled\nby the `negative_impls` feature.)\n\n[`Send`]: https://doc.rust-lang.org/std/marker/trait.Send.html\n[`Sync`]: https://doc.rust-lang.org/std/marker/trait.Sync.html\n\n```rust,ignore\nimpl !Trait for Type\n```\n\nExample:\n\n```rust\n#![feature(negative_impls)]\n#![feature(optin_builtin_traits)]\n\nauto trait Valid {}\n\nstruct True;\nstruct False;\n\nimpl !Valid for False {}\n\nstruct MaybeValid(T);\n\nfn must_be_valid(_t: T) { }\n\nfn main() {\n // works\n must_be_valid( MaybeValid(True) );\n \n // compiler error - trait bound not satisfied\n // must_be_valid( MaybeValid(False) );\n}\n```\n\n## Automatic trait implementations\n\nWhen a type is declared as an `auto trait`, we will automatically\ncreate impls for every struct/enum/union, unless an explicit impl is\nprovided. These automatic impls contain a where clause for each field\nof the form `T: AutoTrait`, where `T` is the type of the field and\n`AutoTrait` is the auto trait in question. As an example, consider the\nstruct `List` and the auto trait `Send`:\n\n```rust\nstruct List {\n data: T,\n next: Option>>,\n}\n```\n\nPresuming that there is no explicit impl of `Send` for `List`, the\ncompiler will supply an automatic impl of the form:\n\n```rust\nstruct List {\n data: T,\n next: Option>>,\n}\n\nunsafe impl Send for List\nwhere\n T: Send, // from the field `data`\n Option>>: Send, // from the field `next`\n{ }\n```\n\nExplicit impls may be either positive or negative. They take the form:\n\n```rust,ignore\nimpl<...> AutoTrait for StructName<..> { }\nimpl<...> !AutoTrait for StructName<..> { }\n```\n\n## Coinduction: Auto traits permit cyclic matching\n\nUnlike ordinary trait matching, auto traits are **coinductive**. This\nmeans, in short, that cycles which occur in trait matching are\nconsidered ok. As an example, consider the recursive struct `List`\nintroduced in the previous section. In attempting to determine whether\n`List: Send`, we would wind up in a cycle: to apply the impl, we must\nshow that `Option>: Send`, which will in turn require\n`Box: Send` and then finally `List: Send` again. Under ordinary\ntrait matching, this cycle would be an error, but for an auto trait it\nis considered a successful match.\n\n## Items\n\nAuto traits cannot have any trait items, such as methods or associated types. This ensures that we can generate default implementations.\n\n## Supertraits\n\nAuto traits cannot have supertraits. This is for soundness reasons, as the interaction of coinduction with implied bounds is difficult to reconcile.\n\n" } , LintCompletion { label : "rustc_attrs" , description : "# `rustc_attrs`\n\nThis feature has no tracking issue, and is therefore internal to\nthe compiler, not being intended for general use.\n\nNote: `rustc_attrs` enables many rustc-internal attributes and this page\nonly discuss a few of them.\n\n------------------------\n\nThe `rustc_attrs` feature allows debugging rustc type layouts by using\n`#[rustc_layout(...)]` to debug layout at compile time (it even works\nwith `cargo check`) as an alternative to `rustc -Z print-type-sizes`\nthat is way more verbose.\n\nOptions provided by `#[rustc_layout(...)]` are `debug`, `size`, `abi`.\nNote that it only work best with sized type without generics.\n\n## Examples\n\n```rust,ignore\n#![feature(rustc_attrs)]\n\n#[rustc_layout(abi, size)]\npub enum X {\n Y(u8, u8, u8),\n Z(isize),\n}\n```\n\nWhen that is compiled, the compiler will error with something like\n\n```text\nerror: abi: Aggregate { sized: true }\n --> src/lib.rs:4:1\n |\n4 | / pub enum T {\n5 | | Y(u8, u8, u8),\n6 | | Z(isize),\n7 | | }\n | |_^\n\nerror: size: Size { raw: 16 }\n --> src/lib.rs:4:1\n |\n4 | / pub enum T {\n5 | | Y(u8, u8, u8),\n6 | | Z(isize),\n7 | | }\n | |_^\n\nerror: aborting due to 2 previous errors\n```\n" } , LintCompletion { label : "non_ascii_idents" , description : "# `non_ascii_idents`\n\nThe tracking issue for this feature is: [#55467]\n\n[#55467]: https://github.com/rust-lang/rust/issues/55467\n\n------------------------\n\nThe `non_ascii_idents` feature adds support for non-ASCII identifiers.\n\n## Examples\n\n```rust\n#![feature(non_ascii_idents)]\n\nconst ε: f64 = 0.00001f64;\nconst Π: f64 = 3.14f64;\n```\n\n## Changes to the language reference\n\n> **Lexer:** \n> IDENTIFIER : \n>       XID_start XID_continue\\* \n>    | `_` XID_continue+ \n\nAn identifier is any nonempty Unicode string of the following form:\n\nEither\n\n * The first character has property [`XID_start`]\n * The remaining characters have property [`XID_continue`]\n\nOr\n\n * The first character is `_`\n * The identifier is more than one character, `_` alone is not an identifier\n * The remaining characters have property [`XID_continue`]\n\nthat does _not_ occur in the set of [strict keywords].\n\n> **Note**: [`XID_start`] and [`XID_continue`] as character properties cover the\n> character ranges used to form the more familiar C and Java language-family\n> identifiers.\n\n[`XID_start`]: http://unicode.org/cldr/utility/list-unicodeset.jsp?a=%5B%3AXID_Start%3A%5D&abb=on&g=&i=\n[`XID_continue`]: http://unicode.org/cldr/utility/list-unicodeset.jsp?a=%5B%3AXID_Continue%3A%5D&abb=on&g=&i=\n[strict keywords]: ../../reference/keywords.md#strict-keywords\n" } , LintCompletion { label : "box_syntax" , description : "# `box_syntax`\n\nThe tracking issue for this feature is: [#49733]\n\n[#49733]: https://github.com/rust-lang/rust/issues/49733\n\nSee also [`box_patterns`](box-patterns.md)\n\n------------------------\n\nCurrently the only stable way to create a `Box` is via the `Box::new` method.\nAlso it is not possible in stable Rust to destructure a `Box` in a match\npattern.

The marker is the attribute `#[lang = \"...\"]` and there are\nvarious different values of `...`, i.e. various different 'lang\nitems'.\n\nFor example, `Box` pointers require two lang items, one for allocation\nand one for deallocation. A freestanding program that uses the `Box`\nsugar for dynamic allocations via `malloc` and `free`:\n\n```rust,ignore\n#![feature(lang_items, box_syntax, start, libc, core_intrinsics)]\n#![no_std]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\nextern crate libc;\n\n#[lang = \"owned_box\"]\npub struct Box(*mut T);\n\n#[lang = \"exchange_malloc\"]\nunsafe fn allocate(size: usize, _align: usize) -> *mut u8 {\n let p = libc::malloc(size as libc::size_t) as *mut u8;\n\n // Check if `malloc` failed:\n if p as usize == 0 {\n intrinsics::abort();\n }\n\n p\n}\n\n#[lang = \"box_free\"]\nunsafe fn box_free(ptr: *mut T) {\n libc::free(ptr as *mut libc::c_void)\n}\n\n#[start]\nfn main(_argc: isize, _argv: *const *const u8) -> isize {\n let _x = box 1;\n\n 0\n}\n\n#[lang = \"eh_personality\"] extern fn rust_eh_personality() {}\n#[lang = \"panic_impl\"] extern fn rust_begin_panic(info: &PanicInfo) -> ! { unsafe { intrinsics::abort() } }\n#[no_mangle] pub extern fn rust_eh_register_frames () {}\n#[no_mangle] pub extern fn rust_eh_unregister_frames () {}\n```\n\nNote the use of `abort`: the `exchange_malloc` lang item is assumed to\nreturn a valid pointer, and so needs to do the check internally.\n\nOther features provided by lang items include:\n\n- overloadable operators via traits: the traits corresponding to the\n `==`, `<`, dereferencing (`*`) and `+` (etc.) operators are all\n marked with lang items; those specific four are `eq`, `ord`,\n `deref`, and `add` respectively.\n- stack unwinding and general failure; the `eh_personality`,\n `panic` and `panic_bounds_checks` lang items.\n- the traits in `std::marker` used to indicate types of\n various kinds; lang items `send`, `sync` and `copy`.\n- the marker types and variance indicators found in\n `std::marker`; lang items `covariant_type`,\n `contravariant_lifetime`, etc.\n\nLang items are loaded lazily by the compiler; e.g. if one never uses\n`Box` then there is no need to define functions for `exchange_malloc`\nand `box_free`. `rustc` will emit an error when an item is needed\nbut not found in the current crate or any that it depends on.\n\nMost lang items are defined by `libcore`, but if you're trying to build\nan executable without the standard library, you'll run into the need\nfor lang items. The rest of this page focuses on this use-case, even though\nlang items are a bit broader than that.\n\n### Using libc\n\nIn order to build a `#[no_std]` executable we will need libc as a dependency.\nWe can specify this using our `Cargo.toml` file:\n\n```toml\n[dependencies]\nlibc = { version = \"0.2.14\", default-features = false }\n```\n\nNote that the default features have been disabled. This is a critical step -\n**the default features of libc include the standard library and so must be\ndisabled.**\n\n### Writing an executable without stdlib\n\nControlling the entry point is possible in two ways: the `#[start]` attribute,\nor overriding the default shim for the C `main` function with your own.\n\nThe function marked `#[start]` is passed the command line parameters\nin the same format as C:\n\n```rust,ignore\n#![feature(lang_items, core_intrinsics)]\n#![feature(start)]\n#![no_std]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\n// Pull in the system libc library for what crt0.o likely requires.\nextern crate libc;\n\n// Entry point for this program.\n#[start]\nfn start(_argc: isize, _argv: *const *const u8) -> isize {\n 0\n}\n\n// These functions are used by the compiler, but not\n// for a bare-bones hello world. These are normally\n// provided by libstd.\n#[lang = \"eh_personality\"]\n#[no_mangle]\npub extern fn rust_eh_personality() {\n}\n\n#[lang = \"panic_impl\"]\n#[no_mangle]\npub extern fn rust_begin_panic(info: &PanicInfo) -> ! {\n unsafe { intrinsics::abort() }\n}\n```\n\nTo override the compiler-inserted `main` shim, one has to disable it\nwith `#![no_main]` and then create the appropriate symbol with the\ncorrect ABI and the correct name, which requires overriding the\ncompiler's name mangling too:\n\n```rust,ignore\n#![feature(lang_items, core_intrinsics)]\n#![feature(start)]\n#![no_std]\n#![no_main]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\n// Pull in the system libc library for what crt0.o likely requires.\nextern crate libc;\n\n// Entry point for this program.\n#[no_mangle] // ensure that this symbol is called `main` in the output\npub extern fn main(_argc: i32, _argv: *const *const u8) -> i32 {\n 0\n}\n\n// These functions are used by the compiler, but not\n// for a bare-bones hello world. These are normally\n// provided by libstd.\n#[lang = \"eh_personality\"]\n#[no_mangle]\npub extern fn rust_eh_personality() {\n}\n\n#[lang = \"panic_impl\"]\n#[no_mangle]\npub extern fn rust_begin_panic(info: &PanicInfo) -> ! {\n unsafe { intrinsics::abort() }\n}\n```\n\nIn many cases, you may need to manually link to the `compiler_builtins` crate\nwhen building a `no_std` binary. You may observe this via linker error messages\nsuch as \"```undefined reference to `__rust_probestack'```\".\n\n## More about the language items\n\nThe compiler currently makes a few assumptions about symbols which are\navailable in the executable to call. Normally these functions are provided by\nthe standard library, but without it you must define your own. These symbols\nare called \"language items\", and they each have an internal name, and then a\nsignature that an implementation must conform to.\n\nThe first of these functions, `rust_eh_personality`, is used by the failure\nmechanisms of the compiler. This is often mapped to GCC's personality function\n(see the [libstd implementation][unwind] for more information), but crates\nwhich do not trigger a panic can be assured that this function is never\ncalled.

Negative impls are a commitment not to implement the given trait for the named types.\n\n## Orphan and overlap rules\n\nNegative impls must obey the same orphan rules as a positive impl. This implies you cannot add a negative impl for types defined in upstream crates and so forth.\n\nSimilarly, negative impls cannot overlap with positive impls, again using the same \"overlap\" check that we ordinarily use to determine if two impls overlap. (Note that positive impls typically cannot overlap with one another either, except as permitted by specialization.)\n\n## Interaction with auto traits\n\nDeclaring a negative impl `impl !SomeAutoTrait for SomeType` for an\nauto-trait serves two purposes:\n\n* as with any trait, it declares that `SomeType` will never implement `SomeAutoTrait`;\n* it disables the automatic `SomeType: SomeAutoTrait` impl that would otherwise have been generated.\n\nNote that, at present, there is no way to indicate that a given type\ndoes not implement an auto trait *but that it may do so in the\nfuture*. For ordinary types, this is done by simply not declaring any\nimpl at all, but that is not an option for auto traits. A workaround\nis that one could embed a marker type as one of the fields, where the\nmarker type is `!AutoTrait`.\n\n## Immediate uses\n\nNegative impls are used to declare that `&T: !DerefMut` and `&mut T: !Clone`, as required to fix the soundness of `Pin` described in [#66544](https://github.com/rust-lang/rust/issues/66544).\n\nThis serves two purposes:\n\n* For proving the correctness of unsafe code, we can use that impl as evidence that no `DerefMut` or `Clone` impl exists.\n* It prevents downstream crates from creating such impls.\n" } , LintCompletion { label : "abi_ptx" , description : "# `abi_ptx`\n\nThe tracking issue for this feature is: [#38788]\n\n[#38788]: https://github.com/rust-lang/rust/issues/38788\n\n------------------------\n\nWhen emitting PTX code, all vanilla Rust functions (`fn`) get translated to\n\"device\" functions.

This is\ngenerally unwanted unless you are building another plugin.\n\nThe usual practice is to put compiler plugins in their own crate, separate from\nany `macro_rules!` macros or ordinary Rust code meant to be used by consumers\nof a library.\n\n# Lint plugins\n\nPlugins can extend [Rust's lint\ninfrastructure](../../reference/attributes/diagnostics.md#lint-check-attributes) with\nadditional checks for code style, safety, etc. Now let's write a plugin\n[`lint-plugin-test.rs`](https://github.com/rust-lang/rust/blob/master/src/test/ui-fulldeps/auxiliary/lint-plugin-test.rs)\nthat warns about any item named `lintme`.\n\n```rust,ignore\n#![feature(plugin_registrar)]\n#![feature(box_syntax, rustc_private)]\n\nextern crate rustc_ast;\n\n// Load rustc as a plugin to get macros\nextern crate rustc_driver;\n#[macro_use]\nextern crate rustc_lint;\n#[macro_use]\nextern crate rustc_session;\n\nuse rustc_driver::plugin::Registry;\nuse rustc_lint::{EarlyContext, EarlyLintPass, LintArray, LintContext, LintPass};\nuse rustc_ast::ast;\ndeclare_lint!(TEST_LINT, Warn, \"Warn about items named 'lintme'\");\n\ndeclare_lint_pass!(Pass => [TEST_LINT]);\n\nimpl EarlyLintPass for Pass {\n fn check_item(&mut self, cx: &EarlyContext, it: &ast::Item) {\n if it.ident.name.as_str() == \"lintme\" {\n cx.lint(TEST_LINT, |lint| {\n lint.build(\"item is named 'lintme'\").set_span(it.span).emit()\n });\n }\n }\n}\n\n#[plugin_registrar]\npub fn plugin_registrar(reg: &mut Registry) {\n reg.lint_store.register_lints(&[&TEST_LINT]);\n reg.lint_store.register_early_pass(|| box Pass);\n}\n```\n\nThen code like\n\n```rust,ignore\n#![feature(plugin)]\n#![plugin(lint_plugin_test)]\n\nfn lintme() { }\n```\n\nwill produce a compiler warning:\n\n```txt\nfoo.rs:4:1: 4:16 warning: item is named 'lintme', #[warn(test_lint)] on by default\nfoo.rs:4 fn lintme() { }\n ^~~~~~~~~~~~~~~\n```\n\nThe components of a lint plugin are:\n\n* one or more `declare_lint!` invocations, which define static `Lint` structs;\n\n* a struct holding any state needed by the lint pass (here, none);\n\n* a `LintPass`\n implementation defining how to check each syntax element. A single\n `LintPass` may call `span_lint` for several different `Lint`s, but should\n register them all through the `get_lints` method.\n\nLint passes are syntax traversals, but they run at a late stage of compilation\nwhere type information is available. `rustc`'s [built-in\nlints](https://github.com/rust-lang/rust/blob/master/src/librustc_session/lint/builtin.rs)\nmostly use the same infrastructure as lint plugins, and provide examples of how\nto access type information.\n\nLints defined by plugins are controlled by the usual [attributes and compiler\nflags](../../reference/attributes/diagnostics.md#lint-check-attributes), e.g.\n`#[allow(test_lint)]` or `-A test-lint`. These identifiers are derived from the\nfirst argument to `declare_lint!`, with appropriate case and punctuation\nconversion.\n\nYou can run `rustc -W help foo.rs` to see a list of lints known to `rustc`,\nincluding those provided by plugins loaded by `foo.rs`.\n" } , LintCompletion { label : "concat_idents" , description : "# `concat_idents`\n\nThe tracking issue for this feature is: [#29599]\n\n[#29599]: https://github.com/rust-lang/rust/issues/29599\n\n------------------------\n\nThe `concat_idents` feature adds a macro for concatenating multiple identifiers\ninto one identifier.\n\n## Examples\n\n```rust\n#![feature(concat_idents)]\n\nfn main() {\n fn foobar() -> u32 { 23 }\n let f = concat_idents!(foo, bar);\n assert_eq!(f(), 23);\n}\n```" } , LintCompletion { label : "update_panic_count" , description : "# `update_panic_count`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "fn_traits" , description : "# `fn_traits`\n\nThe tracking issue for this feature is [#29625]\n\nSee Also: [`unboxed_closures`](../language-features/unboxed-closures.md)\n\n[#29625]: https://github.com/rust-lang/rust/issues/29625\n\n----\n\nThe `fn_traits` feature allows for implementation of the [`Fn*`] traits\nfor creating custom closure-like types.\n\n[`Fn*`]: https://doc.rust-lang.org/std/ops/trait.Fn.html\n\n```rust\n#![feature(unboxed_closures)]\n#![feature(fn_traits)]\n\nstruct Adder {\n a: u32\n}\n\nimpl FnOnce<(u32, )> for Adder {\n type Output = u32;\n extern \"rust-call\" fn call_once(self, b: (u32, )) -> Self::Output {\n self.a + b.0\n }\n}\n\nfn main() {\n let adder = Adder { a: 3 };\n assert_eq!(adder(2), 5);\n}\n```\n" } , LintCompletion { label : "try_trait" , description : "# `try_trait`\n\nThe tracking issue for this feature is: [#42327]\n\n[#42327]: https://github.com/rust-lang/rust/issues/42327\n\n------------------------\n\nThis introduces a new trait `Try` for extending the `?` operator to types\nother than `Result` (a part of [RFC 1859]).

The macro is a no-frills\ninterface to LLVM's concept of [module-level inline assembly]. That is,\nall caveats applicable to LLVM's module-level inline assembly apply\nto `global_asm!`.\n\n[module-level inline assembly]: http://llvm.org/docs/LangRef.html#module-level-inline-assembly\n\n`global_asm!` fills a role not currently satisfied by either `asm!`\nor `#[naked]` functions. The programmer has _all_ features of the\nassembler at their disposal. The linker will expect to resolve any\nsymbols defined in the inline assembly, modulo any symbols marked as\nexternal. It also means syntax for directives and assembly follow the\nconventions of the assembler in your toolchain.\n\nA simple usage looks like this:\n\n```rust,ignore\n# #![feature(global_asm)]\n# you also need relevant target_arch cfgs\nglobal_asm!(include_str!(\"something_neato.s\"));\n```\n\nAnd a more complicated usage looks like this:\n\n```rust,ignore\n# #![feature(global_asm)]\n# #![cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n\npub mod sally {\n global_asm!(r#\"\n .global foo\n foo:\n jmp baz\n \"#);\n\n #[no_mangle]\n pub unsafe extern \"C\" fn baz() {}\n}\n\n// the symbols `foo` and `bar` are global, no matter where\n// `global_asm!` was used.\nextern \"C\" {\n fn foo();\n fn bar();\n}\n\npub mod harry {\n global_asm!(r#\"\n .global bar\n bar:\n jmp quux\n \"#);\n\n #[no_mangle]\n pub unsafe extern \"C\" fn quux() {}\n}\n```\n\nYou may use `global_asm!` multiple times, anywhere in your crate, in\nwhatever way suits you. The effect is as if you concatenated all\nusages and placed the larger, single usage in the crate root.\n\n------------------------\n\nIf you don't need quite as much power and flexibility as\n`global_asm!` provides, and you don't mind restricting your inline\nassembly to `fn` bodies only, you might try the\n[asm](asm.md) feature instead.\n" } , LintCompletion { label : "sort_internals" , description : "# `sort_internals`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "test" , description : "# `test`\n\nThe tracking issue for this feature is: None.\n\n------------------------\n\nThe internals of the `test` crate are unstable, behind the `test` flag. The\nmost widely used part of the `test` crate are benchmark tests, which can test\nthe performance of your code. Let's make our `src/lib.rs` look like this\n(comments elided):\n\n```rust,ignore\n#![feature(test)]\n\nextern crate test;\n\npub fn add_two(a: i32) -> i32 {\n a + 2\n}\n\n#[cfg(test)]\nmod tests {\n use super::*;\n use test::Bencher;\n\n #[test]\n fn it_works() {\n assert_eq!(4, add_two(2));\n }\n\n #[bench]\n fn bench_add_two(b: &mut Bencher) {\n b.iter(|| add_two(2));\n }\n}\n```\n\nNote the `test` feature gate, which enables this unstable feature.\n\nWe've imported the `test` crate, which contains our benchmarking support.\nWe have a new function as well, with the `bench` attribute. Unlike regular\ntests, which take no arguments, benchmark tests take a `&mut Bencher`. This\n`Bencher` provides an `iter` method, which takes a closure. This closure\ncontains the code we'd like to benchmark.\n\nWe can run benchmark tests with `cargo bench`:\n\n```bash\n$ cargo bench\n Compiling adder v0.0.1 (file:///home/steve/tmp/adder)\n Running target/release/adder-91b3e234d4ed382a\n\nrunning 2 tests\ntest tests::it_works ... ignored\ntest tests::bench_add_two ... bench: 1 ns/iter (+/- 0)\n\ntest result: ok. 0 passed; 0 failed; 1 ignored; 1 measured\n```\n\nOur non-benchmark test was ignored. You may have noticed that `cargo bench`\ntakes a bit longer than `cargo test`. This is because Rust runs our benchmark\na number of times, and then takes the average. Because we're doing so little\nwork in this example, we have a `1 ns/iter (+/- 0)`, but this would show\nthe variance if there was one.\n\nAdvice on writing benchmarks:\n\n\n* Move setup code outside the `iter` loop; only put the part you want to measure inside\n* Make the code do \"the same thing\" on each iteration; do not accumulate or change state\n* Make the outer function idempotent too; the benchmark runner is likely to run\n it many times\n* Make the inner `iter` loop short and fast so benchmark runs are fast and the\n calibrator can adjust the run-length at fine resolution\n* Make the code in the `iter` loop do something simple, to assist in pinpointing\n performance improvements (or regressions)\n\n## Gotcha: optimizations\n\nThere's another tricky part to writing benchmarks: benchmarks compiled with\noptimizations activated can be dramatically changed by the optimizer so that\nthe benchmark is no longer benchmarking what one expects. For example, the\ncompiler might recognize that some calculation has no external effects and\nremove it entirely.\n\n```rust,ignore\n#![feature(test)]\n\nextern crate test;\nuse test::Bencher;\n\n#[bench]\nfn bench_xor_1000_ints(b: &mut Bencher) {\n b.iter(|| {\n (0..1000).fold(0, |old, new| old ^ new);\n });\n}\n```\n\ngives the following results\n\n```text\nrunning 1 test\ntest bench_xor_1000_ints ... bench: 0 ns/iter (+/- 0)\n\ntest result: ok. 0 passed; 0 failed; 0 ignored; 1 measured\n```\n\nThe benchmarking runner offers two ways to avoid this. Either, the closure that\nthe `iter` method receives can return an arbitrary value which forces the\noptimizer to consider the result used and ensures it cannot remove the\ncomputation entirely. This could be done for the example above by adjusting the\n`b.iter` call to\n\n```rust\n# struct X;\n# impl X { fn iter(&self, _: F) where F: FnMut() -> T {} } let b = X;\nb.iter(|| {\n // Note lack of `;` (could also use an explicit `return`).\n (0..1000).fold(0, |old, new| old ^ new)\n});\n```\n\nOr, the other option is to call the generic `test::black_box` function, which\nis an opaque \"black box\" to the optimizer and so forces it to consider any\nargument as used.\n\n```rust\n#![feature(test)]\n\nextern crate test;\n\n# fn main() {\n# struct X;\n# impl X { fn iter(&self, _: F) where F: FnMut() -> T {} } let b = X;\nb.iter(|| {\n let n = test::black_box(1000);\n\n (0..n).fold(0, |a, b| a ^ b)\n})\n# }\n```\n\nNeither of these read or modify the value, and are very cheap for small values.\nLarger values can be passed indirectly to reduce overhead (e.g.\n`black_box(&huge_struct)`).\n\nPerforming either of the above changes gives the following benchmarking results\n\n```text\nrunning 1 test\ntest bench_xor_1000_ints ... bench: 131 ns/iter (+/- 3)\n\ntest result: ok. 0 passed; 0 failed; 0 ignored; 1 measured\n```\n\nHowever, the optimizer can still modify a testcase in an undesirable manner\neven when using either of the above.\n" } , LintCompletion { label : "windows_stdio" , description : "# `windows_stdio`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "allocator_api" , description : "# `allocator_api`\n\nThe tracking issue for this feature is [#32838]\n\n[#32838]: https://github.com/rust-lang/rust/issues/32838\n\n------------------------\n\nSometimes you want the memory for one collection to use a different\nallocator than the memory for another collection.

Rust supports using inline\nassembly to do this via the `asm!` macro.\n\n# Guide-level explanation\n[guide-level-explanation]: #guide-level-explanation\n\nRust provides support for inline assembly via the `asm!` macro.\nIt can be used to embed handwritten assembly in the assembly output generated by the compiler.\nGenerally this should not be necessary, but might be where the required performance or timing\ncannot be otherwise achieved. Accessing low level hardware primitives, e.g. in kernel code, may also demand this functionality.\n\n> **Note**: the examples here are given in x86/x86-64 assembly, but ARM, AArch64 and RISC-V are also supported.\n\n## Basic usage\n\nLet us start with the simplest possible example:\n\n```rust,allow_fail\n# #![feature(asm)]\nunsafe {\n asm!(\"nop\");\n}\n```\n\nThis will insert a NOP (no operation) instruction into the assembly generated by the compiler.\nNote that all `asm!` invocations have to be inside an `unsafe` block, as they could insert\narbitrary instructions and break various invariants. The instructions to be inserted are listed\nin the first argument of the `asm!` macro as a string literal.\n\n## Inputs and outputs\n\nNow inserting an instruction that does nothing is rather boring. Let us do something that\nactually acts on data:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet x: u64;\nunsafe {\n asm!(\"mov {}, 5\", out(reg) x);\n}\nassert_eq!(x, 5);\n```\n\nThis will write the value `5` into the `u64` variable `x`.\nYou can see that the string literal we use to specify instructions is actually a template string.\nIt is governed by the same rules as Rust [format strings][format-syntax].\nThe arguments that are inserted into the template however look a bit different then you may\nbe familiar with. First we need to specify if the variable is an input or an output of the\ninline assembly. In this case it is an output. We declared this by writing `out`.\nWe also need to specify in what kind of register the assembly expects the variable.\nIn this case we put it in an arbitrary general purpose register by specifying `reg`.\nThe compiler will choose an appropriate register to insert into\nthe template and will read the variable from there after the inline assembly finishes executing.\n\nLet us see another example that also uses an input:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet i: u64 = 3;\nlet o: u64;\nunsafe {\n asm!(\n \"mov {0}, {1}\",\n \"add {0}, {number}\",\n out(reg) o,\n in(reg) i,\n number = const 5,\n );\n}\nassert_eq!(o, 8);\n```\n\nThis will add `5` to the input in variable `i` and write the result to variable `o`.\nThe particular way this assembly does this is first copying the value from `i` to the output,\nand then adding `5` to it.\n\nThe example shows a few things:\n\nFirst, we can see that `asm!` allows multiple template string arguments; each\none is treated as a separate line of assembly code, as if they were all joined\ntogether with newlines between them. This makes it easy to format assembly\ncode.\n\nSecond, we can see that inputs are declared by writing `in` instead of `out`.\n\nThird, one of our operands has a type we haven't seen yet, `const`.\nThis tells the compiler to expand this argument to value directly inside the assembly template.\nThis is only possible for constants and literals.\n\nFourth, we can see that we can specify an argument number, or name as in any format string.\nFor inline assembly templates this is particularly useful as arguments are often used more than once.\nFor more complex inline assembly using this facility is generally recommended, as it improves\nreadability, and allows reordering instructions without changing the argument order.\n\nWe can further refine the above example to avoid the `mov` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut x: u64 = 3;\nunsafe {\n asm!(\"add {0}, {number}\", inout(reg) x, number = const 5);\n}\nassert_eq!(x, 8);\n```\n\nWe can see that `inout` is used to specify an argument that is both input and output.\nThis is different from specifying an input and output separately in that it is guaranteed to assign both to the same register.\n\nIt is also possible to specify different variables for the input and output parts of an `inout` operand:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet x: u64 = 3;\nlet y: u64;\nunsafe {\n asm!(\"add {0}, {number}\", inout(reg) x => y, number = const 5);\n}\nassert_eq!(y, 8);\n```\n\n## Late output operands\n\nThe Rust compiler is conservative with its allocation of operands. It is assumed that an `out`\ncan be written at any time, and can therefore not share its location with any other argument.\nHowever, to guarantee optimal performance it is important to use as few registers as possible,\nso they won't have to be saved and reloaded around the inline assembly block.\nTo achieve this Rust provides a `lateout` specifier. This can be used on any output that is\nwritten only after all inputs have been consumed.\nThere is also a `inlateout` variant of this specifier.\n\nHere is an example where `inlateout` *cannot* be used:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nlet c: u64 = 4;\nunsafe {\n asm!(\n \"add {0}, {1}\",\n \"add {0}, {2}\",\n inout(reg) a,\n in(reg) b,\n in(reg) c,\n );\n}\nassert_eq!(a, 12);\n```\n\nHere the compiler is free to allocate the same register for inputs `b` and `c` since it knows they have the same value. However it must allocate a separate register for `a` since it uses `inout` and not `inlateout`. If `inlateout` was used, then `a` and `c` could be allocated to the same register, in which case the first instruction to overwrite the value of `c` and cause the assembly code to produce the wrong result.\n\nHowever the following example can use `inlateout` since the output is only modified after all input registers have been read:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nunsafe {\n asm!(\"add {0}, {1}\", inlateout(reg) a, in(reg) b);\n}\nassert_eq!(a, 8);\n```\n\nAs you can see, this assembly fragment will still work correctly if `a` and `b` are assigned to the same register.\n\n## Explicit register operands\n\nSome instructions require that the operands be in a specific register.\nTherefore, Rust inline assembly provides some more specific constraint specifiers.\nWhile `reg` is generally available on any architecture, these are highly architecture specific. E.g. for x86 the general purpose registers `eax`, `ebx`, `ecx`, `edx`, `ebp`, `esi`, and `edi`\namong others can be addressed by their name.\n\n```rust,allow_fail,no_run\n# #![feature(asm)]\nlet cmd = 0xd1;\nunsafe {\n asm!(\"out 0x64, eax\", in(\"eax\") cmd);\n}\n```\n\nIn this example we call the `out` instruction to output the content of the `cmd` variable\nto port `0x64`. Since the `out` instruction only accepts `eax` (and its sub registers) as operand\nwe had to use the `eax` constraint specifier.\n\nNote that unlike other operand types, explicit register operands cannot be used in the template string: you can't use `{}` and should write the register name directly instead. Also, they must appear at the end of the operand list after all other operand types.\n\nConsider this example which uses the x86 `mul` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nfn mul(a: u64, b: u64) -> u128 {\n let lo: u64;\n let hi: u64;\n\n unsafe {\n asm!(\n // The x86 mul instruction takes rax as an implicit input and writes\n // the 128-bit result of the multiplication to rax:rdx.\n \"mul {}\",\n in(reg) a,\n inlateout(\"rax\") b => lo,\n lateout(\"rdx\") hi\n );\n }\n\n ((hi as u128) << 64) + lo as u128\n}\n```\n\nThis uses the `mul` instruction to multiply two 64-bit inputs with a 128-bit result.\nThe only explicit operand is a register, that we fill from the variable `a`.\nThe second operand is implicit, and must be the `rax` register, which we fill from the variable `b`.\nThe lower 64 bits of the result are stored in `rax` from which we fill the variable `lo`.\nThe higher 64 bits are stored in `rdx` from which we fill the variable `hi`.\n\n## Clobbered registers\n\nIn many cases inline assembly will modify state that is not needed as an output.\nUsually this is either because we have to use a scratch register in the assembly,\nor instructions modify state that we don't need to further examine.\nThis state is generally referred to as being \"clobbered\".\nWe need to tell the compiler about this since it may need to save and restore this state\naround the inline assembly block.\n\n```rust,allow_fail\n# #![feature(asm)]\nlet ebx: u32;\nlet ecx: u32;\n\nunsafe {\n asm!(\n \"cpuid\",\n // EAX 4 selects the \"Deterministic Cache Parameters\" CPUID leaf\n inout(\"eax\") 4 => _,\n // ECX 0 selects the L0 cache information.\n inout(\"ecx\") 0 => ecx,\n lateout(\"ebx\") ebx,\n lateout(\"edx\") _,\n );\n}\n\nprintln!(\n \"L1 Cache: {}\",\n ((ebx >> 22) + 1) * (((ebx >> 12) & 0x3ff) + 1) * ((ebx & 0xfff) + 1) * (ecx + 1)\n);\n```\n\nIn the example above we use the `cpuid` instruction to get the L1 cache size.\nThis instruction writes to `eax`, `ebx`, `ecx`, and `edx`, but for the cache size we only care about the contents of `ebx` and `ecx`.\n\nHowever we still need to tell the compiler that `eax` and `edx` have been modified so that it can save any values that were in these registers before the asm. This is done by declaring these as outputs but with `_` instead of a variable name, which indicates that the output value is to be discarded.\n\nThis can also be used with a general register class (e.g. `reg`) to obtain a scratch register for use inside the asm code:\n\n```rust,allow_fail\n# #![feature(asm)]\n// Multiply x by 6 using shifts and adds\nlet mut x: u64 = 4;\nunsafe {\n asm!(\n \"mov {tmp}, {x}\",\n \"shl {tmp}, 1\",\n \"shl {x}, 2\",\n \"add {x}, {tmp}\",\n x = inout(reg) x,\n tmp = out(reg) _,\n );\n}\nassert_eq!(x, 4 * 6);\n```\n\n## Symbol operands\n\nA special operand type, `sym`, allows you to use the symbol name of a `fn` or `static` in inline assembly code.\nThis allows you to call a function or access a global variable without needing to keep its address in a register.\n\n```rust,allow_fail\n# #![feature(asm)]\nextern \"C\" fn foo(arg: i32) {\n println!(\"arg = {}\", arg);\n}\n\nfn call_foo(arg: i32) {\n unsafe {\n asm!(\n \"call {}\",\n sym foo,\n // 1st argument in rdi, which is caller-saved\n inout(\"rdi\") arg => _,\n // All caller-saved registers must be marked as clobberred\n out(\"rax\") _, out(\"rcx\") _, out(\"rdx\") _, out(\"rsi\") _,\n out(\"r8\") _, out(\"r9\") _, out(\"r10\") _, out(\"r11\") _,\n out(\"xmm0\") _, out(\"xmm1\") _, out(\"xmm2\") _, out(\"xmm3\") _,\n out(\"xmm4\") _, out(\"xmm5\") _, out(\"xmm6\") _, out(\"xmm7\") _,\n out(\"xmm8\") _, out(\"xmm9\") _, out(\"xmm10\") _, out(\"xmm11\") _,\n out(\"xmm12\") _, out(\"xmm13\") _, out(\"xmm14\") _, out(\"xmm15\") _,\n )\n }\n}\n```\n\nNote that the `fn` or `static` item does not need to be public or `#[no_mangle]`:\nthe compiler will automatically insert the appropriate mangled symbol name into the assembly code.\n\n## Register template modifiers\n\nIn some cases, fine control is needed over the way a register name is formatted when inserted into the template string. This is needed when an architecture's assembly language has several names for the same register, each typically being a \"view\" over a subset of the register (e.g. the low 32 bits of a 64-bit register).\n\nBy default the compiler will always choose the name that refers to the full register size (e.g. `rax` on x86-64, `eax` on x86, etc).\n\nThis default can be overriden by using modifiers on the template string operands, just like you would with format strings:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut x: u16 = 0xab;\n\nunsafe {\n asm!(\"mov {0:h}, {0:l}\", inout(reg_abcd) x);\n}\n\nassert_eq!(x, 0xabab);\n```\n\nIn this example, we use the `reg_abcd` register class to restrict the register allocator to the 4 legacy x86 register (`ax`, `bx`, `cx`, `dx`) of which the first two bytes can be addressed independently.\n\nLet us assume that the register allocator has chosen to allocate `x` in the `ax` register.\nThe `h` modifier will emit the register name for the high byte of that register and the `l` modifier will emit the register name for the low byte. The asm code will therefore be expanded as `mov ah, al` which copies the low byte of the value into the high byte.\n\nIf you use a smaller data type (e.g. `u16`) with an operand and forget the use template modifiers, the compiler will emit a warning and suggest the correct modifier to use.\n\n## Options\n\nBy default, an inline assembly block is treated the same way as an external FFI function call with a custom calling convention: it may read/write memory, have observable side effects, etc. However in many cases, it is desirable to give the compiler more information about what the assembly code is actually doing so that it can optimize better.\n\nLet's take our previous example of an `add` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nunsafe {\n asm!(\n \"add {0}, {1}\",\n inlateout(reg) a, in(reg) b,\n options(pure, nomem, nostack),\n );\n}\nassert_eq!(a, 8);\n```\n\nOptions can be provided as an optional final argument to the `asm!` macro. We specified three options here:\n- `pure` means that the asm code has no observable side effects and that its output depends only on its inputs. This allows the compiler optimizer to call the inline asm fewer times or even eliminate it entirely.\n- `nomem` means that the asm code does not read or write to memory. By default the compiler will assume that inline assembly can read or write any memory address that is accessible to it (e.g. through a pointer passed as an operand, or a global).\n- `nostack` means that the asm code does not push any data onto the stack. This allows the compiler to use optimizations such as the stack red zone on x86-64 to avoid stack pointer adjustments.\n\nThese allow the compiler to better optimize code using `asm!`, for example by eliminating pure `asm!` blocks whose outputs are not needed.\n\nSee the reference for the full list of available options and their effects.\n\n# Reference-level explanation\n[reference-level-explanation]: #reference-level-explanation\n\nInline assembler is implemented as an unsafe macro `asm!()`.\nThe first argument to this macro is a template string literal used to build the final assembly.\nThe following arguments specify input and output operands.\nWhen required, options are specified as the final argument.\n\nThe following ABNF specifies the general syntax:\n\n```ignore\ndir_spec := \"in\" / \"out\" / \"lateout\" / \"inout\" / \"inlateout\"\nreg_spec := / \"\"\noperand_expr := expr / \"_\" / expr \"=>\" expr / expr \"=>\" \"_\"\nreg_operand := dir_spec \"(\" reg_spec \")\" operand_expr\noperand := reg_operand / \"const\" const_expr / \"sym\" path\noption := \"pure\" / \"nomem\" / \"readonly\" / \"preserves_flags\" / \"noreturn\" / \"att_syntax\"\noptions := \"options(\" option *[\",\" option] [\",\"] \")\"\nasm := \"asm!(\" format_string *(\",\" format_string) *(\",\" [ident \"=\"] operand) [\",\" options] [\",\"] \")\"\n```\n\nThe macro will initially be supported only on ARM, AArch64, Hexagon, x86, x86-64 and RISC-V targets. Support for more targets may be added in the future. The compiler will emit an error if `asm!` is used on an unsupported target.\n\n[format-syntax]: https://doc.rust-lang.org/std/fmt/#syntax\n\n## Template string arguments\n\nThe assembler template uses the same syntax as [format strings][format-syntax] (i.e. placeholders are specified by curly braces). The corresponding arguments are accessed in order, by index, or by name. However, implicit named arguments (introduced by [RFC #2795][rfc-2795]) are not supported.\n\nAn `asm!` invocation may have one or more template string arguments; an `asm!` with multiple template string arguments is treated as if all the strings were concatenated with a `\\n` between them. The expected usage is for each template string argument to correspond to a line of assembly code. All template string arguments must appear before any other arguments.\n\nAs with format strings, named arguments must appear after positional arguments. Explicit register operands must appear at the end of the operand list, after named arguments if any.\n\nExplicit register operands cannot be used by placeholders in the template string. All other named and positional operands must appear at least once in the template string, otherwise a compiler error is generated.\n\nThe exact assembly code syntax is target-specific and opaque to the compiler except for the way operands are substituted into the template string to form the code passed to the assembler.\n\nThe 5 targets specified in this RFC (x86, ARM, AArch64, RISC-V, Hexagon) all use the assembly code syntax of the GNU assembler (GAS). On x86, the `.intel_syntax noprefix` mode of GAS is used by default. On ARM, the `.syntax unified` mode is used. These targets impose an additional restriction on the assembly code: any assembler state (e.g. the current section which can be changed with `.section`) must be restored to its original value at the end of the asm string. Assembly code that does not conform to the GAS syntax will result in assembler-specific behavior.\n\n[rfc-2795]: https://github.com/rust-lang/rfcs/pull/2795\n\n## Operand type\n\nSeveral types of operands are supported:\n\n* `in() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain the value of `` at the start of the asm code.\n - The allocated register must contain the same value at the end of the asm code (except if a `lateout` is allocated to the same register).\n* `out() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain an undefined value at the start of the asm code.\n - `` must be a (possibly uninitialized) place expression, to which the contents of the allocated register is written to at the end of the asm code.\n - An underscore (`_`) may be specified instead of an expression, which will cause the contents of the register to be discarded at the end of the asm code (effectively acting as a clobber).\n* `lateout() `\n - Identical to `out` except that the register allocator can reuse a register allocated to an `in`.\n - You should only write to the register after all inputs are read, otherwise you may clobber an input.\n* `inout() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain the value of `` at the start of the asm code.\n - `` must be a mutable initialized place expression, to which the contents of the allocated register is written to at the end of the asm code.\n* `inout() => `\n - Same as `inout` except that the initial value of the register is taken from the value of ``.\n - `` must be a (possibly uninitialized) place expression, to which the contents of the allocated register is written to at the end of the asm code.\n - An underscore (`_`) may be specified instead of an expression for ``, which will cause the contents of the register to be discarded at the end of the asm code (effectively acting as a clobber).\n - `` and `` may have different types.\n* `inlateout() ` / `inlateout() => `\n - Identical to `inout` except that the register allocator can reuse a register allocated to an `in` (this can happen if the compiler knows the `in` has the same initial value as the `inlateout`).\n - You should only write to the register after all inputs are read, otherwise you may clobber an input.\n* `const `\n - `` must be an integer or floating-point constant expression.\n - The value of the expression is formatted as a string and substituted directly into the asm template string.\n* `sym `\n - `` must refer to a `fn` or `static`.\n - A mangled symbol name referring to the item is substituted into the asm template string.\n - The substituted string does not include any modifiers (e.g. GOT, PLT, relocations, etc).\n - `` is allowed to point to a `#[thread_local]` static, in which case the asm code can combine the symbol with relocations (e.g. `@plt`, `@TPOFF`) to read from thread-local data.\n\nOperand expressions are evaluated from left to right, just like function call arguments. After the `asm!` has executed, outputs are written to in left to right order. This is significant if two outputs point to the same place: that place will contain the value of the rightmost output.\n\n## Register operands\n\nInput and output operands can be specified either as an explicit register or as a register class from which the register allocator can select a register. Explicit registers are specified as string literals (e.g. `\"eax\"`) while register classes are specified as identifiers (e.g. `reg`). Using string literals for register names enables support for architectures that use special characters in register names, such as MIPS (`$0`, `$1`, etc).\n\nNote that explicit registers treat register aliases (e.g. `r14` vs `lr` on ARM) and smaller views of a register (e.g. `eax` vs `rax`) as equivalent to the base register. It is a compile-time error to use the same explicit register for two input operands or two output operands. Additionally, it is also a compile-time error to use overlapping registers (e.g. ARM VFP) in input operands or in output operands.\n\nOnly the following types are allowed as operands for inline assembly:\n- Integers (signed and unsigned)\n- Floating-point numbers\n- Pointers (thin only)\n- Function pointers\n- SIMD vectors (structs defined with `#[repr(simd)]` and which implement `Copy`). This includes architecture-specific vector types defined in `std::arch` such as `__m128` (x86) or `int8x16_t` (ARM).\n\nHere is the list of currently supported register classes:\n\n| Architecture | Register class | Registers | LLVM constraint code |\n| ------------ | -------------- | --------- | -------------------- |\n| x86 | `reg` | `ax`, `bx`, `cx`, `dx`, `si`, `di`, `r[8-15]` (x86-64 only) | `r` |\n| x86 | `reg_abcd` | `ax`, `bx`, `cx`, `dx` | `Q` |\n| x86-32 | `reg_byte` | `al`, `bl`, `cl`, `dl`, `ah`, `bh`, `ch`, `dh` | `q` |\n| x86-64 | `reg_byte` | `al`, `bl`, `cl`, `dl`, `sil`, `dil`, `r[8-15]b`, `ah`\\*, `bh`\\*, `ch`\\*, `dh`\\* | `q` |\n| x86 | `xmm_reg` | `xmm[0-7]` (x86) `xmm[0-15]` (x86-64) | `x` |\n| x86 | `ymm_reg` | `ymm[0-7]` (x86) `ymm[0-15]` (x86-64) | `x` |\n| x86 | `zmm_reg` | `zmm[0-7]` (x86) `zmm[0-31]` (x86-64) | `v` |\n| x86 | `kreg` | `k[1-7]` | `Yk` |\n| AArch64 | `reg` | `x[0-28]`, `x30` | `r` |\n| AArch64 | `vreg` | `v[0-31]` | `w` |\n| AArch64 | `vreg_low16` | `v[0-15]` | `x` |\n| ARM | `reg` | `r[0-5]` `r7`\\*, `r[8-10]`, `r11`\\*, `r12`, `r14` | `r` |\n| ARM (Thumb) | `reg_thumb` | `r[0-r7]` | `l` |\n| ARM (ARM) | `reg_thumb` | `r[0-r10]`, `r12`, `r14` | `l` |\n| ARM | `sreg` | `s[0-31]` | `t` |\n| ARM | `sreg_low16` | `s[0-15]` | `x` |\n| ARM | `dreg` | `d[0-31]` | `w` |\n| ARM | `dreg_low16` | `d[0-15]` | `t` |\n| ARM | `dreg_low8` | `d[0-8]` | `x` |\n| ARM | `qreg` | `q[0-15]` | `w` |\n| ARM | `qreg_low8` | `q[0-7]` | `t` |\n| ARM | `qreg_low4` | `q[0-3]` | `x` |\n| NVPTX | `reg16` | None\\* | `h` |\n| NVPTX | `reg32` | None\\* | `r` |\n| NVPTX | `reg64` | None\\* | `l` |\n| RISC-V | `reg` | `x1`, `x[5-7]`, `x[9-15]`, `x[16-31]` (non-RV32E) | `r` |\n| RISC-V | `freg` | `f[0-31]` | `f` |\n| Hexagon | `reg` | `r[0-28]` | `r` |\n\n> **Note**: On x86 we treat `reg_byte` differently from `reg` because the compiler can allocate `al` and `ah` separately whereas `reg` reserves the whole register.\n>\n> Note #2: On x86-64 the high byte registers (e.g. `ah`) are only available when used as an explicit register. Specifying the `reg_byte` register class for an operand will always allocate a low byte register.\n>\n> Note #3: NVPTX doesn't have a fixed register set, so named registers are not supported.\n>\n> Note #4: On ARM the frame pointer is either `r7` or `r11` depending on the platform.\n\nAdditional register classes may be added in the future based on demand (e.g. MMX, x87, etc).\n\nEach register class has constraints on which value types they can be used with. This is necessary because the way a value is loaded into a register depends on its type. For example, on big-endian systems, loading a `i32x4` and a `i8x16` into a SIMD register may result in different register contents even if the byte-wise memory representation of both values is identical. The availability of supported types for a particular register class may depend on what target features are currently enabled.\n\n| Architecture | Register class | Target feature | Allowed types |\n| ------------ | -------------- | -------------- | ------------- |\n| x86-32 | `reg` | None | `i16`, `i32`, `f32` |\n| x86-64 | `reg` | None | `i16`, `i32`, `f32`, `i64`, `f64` |\n| x86 | `reg_byte` | None | `i8` |\n| x86 | `xmm_reg` | `sse` | `i32`, `f32`, `i64`, `f64`,

The only exception is the `freg` register class on RISC-V where `f32` values are NaN-boxed in a `f64` as required by the RISC-V architecture.\n\nWhen separate input and output expressions are specified for an `inout` operand, both expressions must have the same type. The only exception is if both operands are pointers or integers, in which case they are only required to have the same size. This restriction exists because the register allocators in LLVM and GCC sometimes cannot handle tied operands with different types.\n\n## Register names\n\nSome registers have multiple names.

The frame pointer cannot be used as an input or output. |\n| ARM | `r6` | `r6` is used internally by LLVM as a base pointer and therefore cannot be used as an input or output. |\n| x86 | `k0` | This is a constant zero register which can't be modified. |\n| x86 | `ip` | This is the program counter, not a real register. |\n| x86 | `mm[0-7]` | MMX registers are not currently supported (but may be in the future). |\n| x86 | `st([0-7])` | x87 registers are not currently supported (but may be in the future). |\n| AArch64 | `xzr` | This is a constant zero register which can't be modified. |\n| ARM | `pc` | This is the program counter, not a real register. |\n| RISC-V | `x0` | This is a constant zero register which can't be modified. |\n| RISC-V | `gp`, `tp` | These registers are reserved and cannot be used as inputs or outputs. |\n| Hexagon | `lr` | This is the link register which cannot be used as an input or output. |\n\n## Template modifiers\n\nThe placeholders can be augmented by modifiers which are specified after the `:` in the curly braces. These modifiers do not affect register allocation, but change the way operands are formatted when inserted into the template string. Only one modifier is allowed per template placeholder.\n\nThe supported modifiers are a subset of LLVM's (and GCC's) [asm template argument modifiers][llvm-argmod], but do not use the same letter codes.\n\n| Architecture | Register class | Modifier | Example output | LLVM modifier |\n| ------------ | -------------- | -------- | -------------- | ------------- |\n| x86-32 | `reg` | None | `eax` | `k` |\n| x86-64 | `reg` | None | `rax` | `q` |\n| x86-32 | `reg_abcd` | `l` | `al` | `b` |\n| x86-64 | `reg` | `l` | `al` | `b` |\n| x86 | `reg_abcd` | `h` | `ah` | `h` |\n| x86 | `reg` | `x` | `ax` | `w` |\n| x86 | `reg` | `e` | `eax` | `k` |\n| x86-64 | `reg` | `r` | `rax` | `q` |\n| x86 | `reg_byte` | None | `al` / `ah` | None |\n| x86 | `xmm_reg` | None | `xmm0` | `x` |\n| x86 | `ymm_reg` | None | `ymm0` | `t` |\n| x86 | `zmm_reg` | None | `zmm0` | `g` |\n| x86 | `*mm_reg` | `x` | `xmm0` | `x` |\n| x86 | `*mm_reg` | `y` | `ymm0` | `t` |\n| x86 | `*mm_reg` | `z` | `zmm0` | `g` |\n| x86 | `kreg` | None | `k1` | None |\n| AArch64 | `reg` | None | `x0` | `x` |\n| AArch64 | `reg` | `w` | `w0` | `w` |\n| AArch64 | `reg` | `x` | `x0` | `x` |\n| AArch64 | `vreg` | None | `v0` | None |\n| AArch64 | `vreg` | `v` | `v0` | None |\n| AArch64 | `vreg` | `b` | `b0` | `b` |\n| AArch64 | `vreg` | `h` | `h0` | `h` |\n| AArch64 | `vreg` | `s` | `s0` | `s` |\n| AArch64 | `vreg` | `d` | `d0` | `d` |\n| AArch64 | `vreg` | `q` | `q0` | `q` |\n| ARM | `reg` | None | `r0` | None |\n| ARM | `sreg` | None | `s0` | None |\n| ARM | `dreg` | None | `d0` | `P` |\n| ARM | `qreg` | None | `q0` | `q` |\n| ARM | `qreg` | `e` / `f` | `d0` / `d1` | `e` / `f` |\n| NVPTX | `reg16` | None | `rs0` | None |\n| NVPTX | `reg32` | None | `r0` | None |\n| NVPTX | `reg64` | None | `rd0` | None |\n| RISC-V | `reg` | None | `x1` | None |\n| RISC-V | `freg` | None | `f0` | None |\n| Hexagon | `reg` | None | `r0` | None |\n\n> Notes:\n> - on ARM `e` / `f`: this prints the low or high doubleword register name of a NEON quad (128-bit) register.\n> - on x86: our behavior for `reg` with no modifiers differs from what GCC does. GCC will infer the modifier based on the operand value type, while we default to the full register size.\n> - on x86 `xmm_reg`: the `x`, `t` and `g` LLVM modifiers are not yet implemented in LLVM (they are supported by GCC only), but this should be a simple change.\n\nAs stated in the previous section, passing an input value smaller than the register width will result in the upper bits of the register containing undefined values. This is not a problem if the inline asm only accesses the lower bits of the register, which can be done by using a template modifier to use a subregister name in the asm code (e.g. `ax` instead of `rax`). Since this an easy pitfall, the compiler will suggest a template modifier to use where appropriate given the input type. If all references to an operand already have modifiers then the warning is suppressed for that operand.\n\n[llvm-argmod]: http://llvm.org/docs/LangRef.html#asm-template-argument-modifiers\n\n## Options\n\nFlags are used to further influence the behavior of the inline assembly block.\nCurrently the following options are defined:\n- `pure`: The `asm` block has no side effects, and its outputs depend only on its direct inputs (i.e. the values themselves, not what they point to) or values read from memory (unless the `nomem` options is also set). This allows the compiler to execute the `asm` block fewer times than specified in the program (e.g. by hoisting it out of a loop) or even eliminate it entirely if the outputs are not used.\n- `nomem`: The `asm` blocks does not read or write to any memory. This allows the compiler to cache the values of modified global variables in registers across the `asm` block since it knows that they are not read or written to by the `asm`.\n- `readonly`: The `asm` block does not write to any memory. This allows the compiler to cache the values of unmodified global variables in registers across the `asm` block since it knows that they are not written to by the `asm`.\n- `preserves_flags`: The `asm` block does not modify the flags register (defined in the rules below). This allows the compiler to avoid recomputing the condition flags after the `asm` block.\n- `noreturn`: The `asm` block never returns, and its return type is defined as `!` (never). Behavior is undefined if execution falls through past the end of the asm code. A `noreturn` asm block behaves just like a function which doesn't return; notably, local variables in scope are not dropped before it is invoked.\n- `nostack`: The `asm` block does not push data to the stack, or write to the stack red-zone (if supported by the target). If this option is *not* used then the stack pointer is guaranteed to be suitably aligned (according to the target ABI) for a function call.\n- `att_syntax`: This option is only valid on x86, and causes the assembler to use the `.att_syntax prefix` mode of the GNU assembler. Register operands are substituted in with a leading `%`.\n\nThe compiler performs some additional checks on options:\n- The `nomem` and `readonly` options are mutually exclusive: it is a compile-time error to specify both.\n- The `pure` option must be combined with either the `nomem` or `readonly` options, otherwise a compile-time error is emitted.\n- It is a compile-time error to specify `pure` on an asm block with no outputs or only discarded outputs (`_`).\n- It is a compile-time error to specify `noreturn` on an asm block with outputs.\n\n## Rules for inline assembly\n\n- Any registers not specified as inputs will contain an undefined value on entry to the asm block.\n - An \"undefined value\" in the context of inline assembly means that the register can (non-deterministically) have any one of the possible values allowed by the architecture. Notably it is not the same as an LLVM `undef` which can have a different value every time you read it (since such a concept does not exist in assembly code).\n- Any registers not specified as outputs must have the same value upon exiting the asm block as they had on entry, otherwise behavior is undefined.\n - This only applies to registers which can be specified as an input or output. Other registers follow target-specific rules.\n - Note that a `lateout` may be allocated to the same register as an `in`, in which case this rule does not apply. Code should not rely on this however since it depends on the results of register allocation.\n- Behavior is undefined if execution unwinds out of an asm block.\n - This also applies if the assembly code calls a function which then unwinds.\n- The set of memory locations that assembly code is allowed the read and write are the same as those allowed for an FFI function.\n - Refer to the unsafe code guidelines for the exact rules.\n - If the `readonly` option is set, then only memory reads are allowed.\n - If the `nomem` option is set then no reads or writes to memory are allowed.\n - These rules do not apply to memory which is private to the asm code, such as stack space allocated within the asm block.\n- The compiler cannot assume that the instructions in the asm are the ones that will actually end up executed.\n - This effectively means that the compiler must treat the `asm!` as a black box and only take the interface specification into account, not the instructions themselves.\n - Runtime code patching is allowed, via target-specific mechanisms (outside the scope of this RFC).\n- Unless the `nostack` option is set, asm code is allowed to use stack space below the stack pointer.\n - On entry to the asm block the stack pointer is guaranteed to be suitably aligned (according to the target ABI) for a function call.\n - You are responsible for making sure you don't overflow the stack (e.g. use stack probing to ensure you hit a guard page).\n - You should adjust the stack pointer when allocating stack memory as required by the target ABI.\n - The stack pointer must be restored to its original value before leaving the asm block.\n- If the `noreturn` option is set then behavior is undefined if execution falls through to the end of the asm block.\n- If the `pure` option is set then behavior is undefined if the `asm` has side-effects other than its direct outputs. Behavior is also undefined if two executions of the `asm` code with the same inputs result in different outputs.\n - When used with the `nomem` option, \"inputs\" are just the direct inputs of the `asm!`.\n - When used with the `readonly` option, \"inputs\" comprise the direct inputs of the `asm!` and any memory that the `asm!` block is allowed to read.\n- These flags registers must be restored upon exiting the asm block if the `preserves_flags` option is set:\n - x86\n - Status flags in `EFLAGS` (CF, PF, AF, ZF, SF, OF).\n - Floating-point status word (all).\n - Floating-point exception flags in `MXCSR` (PE, UE, OE, ZE, DE, IE).\n - ARM\n - Condition flags in `CPSR` (N, Z, C, V)\n - Saturation flag in `CPSR` (Q)\n - Greater than or equal flags in `CPSR` (GE).\n - Condition flags in `FPSCR` (N, Z, C, V)\n - Saturation flag in `FPSCR` (QC)\n - Floating-point exception flags in `FPSCR` (IDC, IXC, UFC, OFC, DZC, IOC).\n - AArch64\n - Condition flags (`NZCV` register).\n - Floating-point status (`FPSR` register).\n - RISC-V\n - Floating-point exception flags in `fcsr` (`fflags`).\n- On x86, the direction flag (DF in `EFLAGS`) is clear on entry to an asm block and must be clear on exit.\n - Behavior is undefined if the direction flag is set on exiting an asm block.\n- The requirement of restoring the stack pointer and non-output registers to their original value only applies when exiting an `asm!` block.\n - This means that `asm!` blocks that never return (even if not marked `noreturn`) don't need to preserve these registers.\n - When returning to a different `asm!` block than you entered (e.g. for context switching), these registers must contain the value they had upon entering the `asm!` block that you are *exiting*.\n - You cannot exit an `asm!` block that has not been entered. Neither can you exit an `asm!` block that has already been exited.\n - You are responsible for switching any target-specific state (e.g. thread-local storage, stack bounds).\n - The set of memory locations that you may access is the intersection of those allowed by the `asm!` blocks you entered and exited.\n- You cannot assume that an `asm!` block will appear exactly once in the output binary. The compiler is allowed to instantiate multiple copies of the `asm!` block, for example when the function containing it is inlined in multiple places.\n - As a consequence, you should only use [local labels] inside inline assembly code. Defining symbols in assembly code may lead to assembler and/or linker errors due to duplicate symbol definitions.\n\n> **Note**: As a general rule, the flags covered by `preserves_flags` are those which are *not* preserved when performing a function call.\n\n[local labels]: https://sourceware.org/binutils/docs/as/Symbol-Names.html#Local-Labels\n" } , LintCompletion { label : "is_sorted" ,

This is useful for very low level programming, where\nwhich register you use is important:\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# unsafe fn read_byte_in(port: u16) -> u8 {\nlet result: u8;\nllvm_asm!(\"in %dx, %al\" : \"={al}\"(result) : \"{dx}\"(port));\nresult\n# }\n```\n\n## Clobbers\n\nSome instructions modify registers which might otherwise have held\ndifferent values so we use the clobbers list to indicate to the\ncompiler not to assume any values loaded into those registers will\nstay valid.\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# fn main() { unsafe {\n// Put the value 0x200 in eax:\nllvm_asm!(\"mov $$0x200, %eax\" : /* no outputs */ : /* no inputs */ : \"eax\");\n# } }\n# #[cfg(not(any(target_arch = \"x86\", target_arch = \"x86_64\")))]\n# fn main() {}\n```\n\nInput and output registers need not be listed since that information\nis already communicated by the given constraints. Otherwise, any other\nregisters used either implicitly or explicitly should be listed.\n\nIf the assembly changes the condition code register `cc` should be\nspecified as one of the clobbers. Similarly, if the assembly modifies\nmemory, `memory` should also be specified.\n\n## Options\n\nThe last section, `options` is specific to Rust. The format is comma\nseparated literal strings (i.e. `:\"foo\", \"bar\", \"baz\"`). It's used to\nspecify some extra info about the inline assembly:\n\nCurrent valid options are:\n\n1. *volatile* - specifying this is analogous to\n `__asm__ __volatile__ (...)` in gcc/clang.\n2. *alignstack* - certain instructions expect the stack to be\n aligned a certain way (i.e. SSE) and specifying this indicates to\n the compiler to insert its usual stack alignment code\n3. *intel* - use intel syntax instead of the default AT&T.\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# fn main() {\nlet result: i32;\nunsafe {\n llvm_asm!(\"mov eax, 2\" : \"={eax}\"(result) : : : \"intel\")\n}\nprintln!(\"eax is currently {}\", result);\n# }\n# #[cfg(not(any(target_arch = \"x86\", target_arch = \"x86_64\")))]\n# fn main() {}\n```\n\n## More Information\n\nThe current implementation of the `llvm_asm!` macro is a direct binding to [LLVM's\ninline assembler expressions][llvm-docs], so be sure to check out [their\ndocumentation as well][llvm-docs] for more information about clobbers,\nconstraints, etc.\n\n[llvm-docs]: http://llvm.org/docs/LangRef.html#inline-assembler-expressions\n\nIf you need more power and don't mind losing some of the niceties of\n`llvm_asm!`, check out [global_asm](global-asm.md).\n" } ] ; +# [ rustfmt :: skip ] pub const UNSTABLE_FEATURE_DESCRIPTOR : & [ LintCompletion ] = & [ LintCompletion { label : "crate_visibility_modifier" , description : "# `crate_visibility_modifier`\n\nThe tracking issue for this feature is: [#53120]\n\n[#53120]: https://github.com/rust-lang/rust/issues/53120\n\n-----\n\nThe `crate_visibility_modifier` feature allows the `crate` keyword to be used\nas a visibility modifier synonymous to `pub(crate)`, indicating that a type\n(function, _&c._) is to be visible to the entire enclosing crate, but not to\nother crates.\n\n```rust\n#![feature(crate_visibility_modifier)]\n\ncrate struct Foo {\n bar: usize,\n}\n```\n" } , LintCompletion { label : "abi_thiscall" , description : "# `abi_thiscall`\n\nThe tracking issue for this feature is: [#42202]\n\n[#42202]: https://github.com/rust-lang/rust/issues/42202\n\n------------------------\n\nThe MSVC ABI on x86 Windows uses the `thiscall` calling convention for C++\ninstance methods by default; it is identical to the usual (C) calling\nconvention on x86 Windows except that the first parameter of the method,\nthe `this` pointer, is passed in the ECX register.\n" } , LintCompletion { label : "infer_static_outlives_requirements" , description : "# `infer_static_outlives_requirements`\n\nThe tracking issue for this feature is: [#54185]\n\n[#54185]: https://github.com/rust-lang/rust/issues/54185\n\n------------------------\nThe `infer_static_outlives_requirements` feature indicates that certain\n`'static` outlives requirements can be inferred by the compiler rather than\nstating them explicitly.\n\nNote: It is an accompanying feature to `infer_outlives_requirements`,\nwhich must be enabled to infer outlives requirements.\n\nFor example, currently generic struct definitions that contain\nreferences, require where-clauses of the form T: 'static.

A generator is a \"resumable function\" that syntactically\nresembles a closure but compiles to much different semantics in the compiler\nitself. The primary feature of a generator is that it can be suspended during\nexecution to be resumed at a later date. Generators use the `yield` keyword to\n\"return\", and then the caller can `resume` a generator to resume execution just\nafter the `yield` keyword.\n\nGenerators are an extra-unstable feature in the compiler right now. Added in\n[RFC 2033] they're mostly intended right now as a information/constraint\ngathering phase. The intent is that experimentation can happen on the nightly\ncompiler before actual stabilization. A further RFC will be required to\nstabilize generators/coroutines and will likely contain at least a few small\ntweaks to the overall design.\n\n[RFC 2033]: https://github.com/rust-lang/rfcs/pull/2033\n\nA syntactical example of a generator is:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::{Generator, GeneratorState};\nuse std::pin::Pin;\n\nfn main() {\n let mut generator = || {\n yield 1;\n return \"foo\"\n };\n\n match Pin::new(&mut generator).resume(()) {\n GeneratorState::Yielded(1) => {}\n _ => panic!(\"unexpected value from resume\"),\n }\n match Pin::new(&mut generator).resume(()) {\n GeneratorState::Complete(\"foo\") => {}\n _ => panic!(\"unexpected value from resume\"),\n }\n}\n```\n\nGenerators are closure-like literals which can contain a `yield` statement. The\n`yield` statement takes an optional expression of a value to yield out of the\ngenerator. All generator literals implement the `Generator` trait in the\n`std::ops` module. The `Generator` trait has one main method, `resume`, which\nresumes execution of the generator at the previous suspension point.\n\nAn example of the control flow of generators is that the following example\nprints all numbers in order:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::Generator;\nuse std::pin::Pin;\n\nfn main() {\n let mut generator = || {\n println!(\"2\");\n yield;\n println!(\"4\");\n };\n\n println!(\"1\");\n Pin::new(&mut generator).resume(());\n println!(\"3\");\n Pin::new(&mut generator).resume(());\n println!(\"5\");\n}\n```\n\nAt this time the main intended use case of generators is an implementation\nprimitive for async/await syntax, but generators will likely be extended to\nergonomic implementations of iterators and other primitives in the future.\nFeedback on the design and usage is always appreciated!\n\n### The `Generator` trait\n\nThe `Generator` trait in `std::ops` currently looks like:\n\n```rust\n# #![feature(arbitrary_self_types, generator_trait)]\n# use std::ops::GeneratorState;\n# use std::pin::Pin;\n\npub trait Generator {\n type Yield;\n type Return;\n fn resume(self: Pin<&mut Self>, resume: R) -> GeneratorState;\n}\n```\n\nThe `Generator::Yield` type is the type of values that can be yielded with the\n`yield` statement. The `Generator::Return` type is the returned type of the\ngenerator. This is typically the last expression in a generator's definition or\nany value passed to `return` in a generator. The `resume` function is the entry\npoint for executing the `Generator` itself.\n\nThe return value of `resume`, `GeneratorState`, looks like:\n\n```rust\npub enum GeneratorState {\n Yielded(Y),\n Complete(R),\n}\n```\n\nThe `Yielded` variant indicates that the generator can later be resumed. This\ncorresponds to a `yield` point in a generator. The `Complete` variant indicates\nthat the generator is complete and cannot be resumed again. Calling `resume`\nafter a generator has returned `Complete` will likely result in a panic of the\nprogram.\n\n### Closure-like semantics\n\nThe closure-like syntax for generators alludes to the fact that they also have\nclosure-like semantics. Namely:\n\n* When created, a generator executes no code. A closure literal does not\n actually execute any of the closure's code on construction, and similarly a\n generator literal does not execute any code inside the generator when\n constructed.\n\n* Generators can capture outer variables by reference or by move, and this can\n be tweaked with the `move` keyword at the beginning of the closure. Like\n closures all generators will have an implicit environment which is inferred by\n the compiler. Outer variables can be moved into a generator for use as the\n generator progresses.\n\n* Generator literals produce a value with a unique type which implements the\n `std::ops::Generator` trait. This allows actual execution of the generator\n through the `Generator::resume` method as well as also naming it in return\n types and such.\n\n* Traits like `Send` and `Sync` are automatically implemented for a `Generator`\n depending on the captured variables of the environment. Unlike closures,\n generators also depend on variables live across suspension points. This means\n that although the ambient environment may be `Send` or `Sync`, the generator\n itself may not be due to internal variables live across `yield` points being\n not-`Send` or not-`Sync`. Note that generators do\n not implement traits like `Copy` or `Clone` automatically.\n\n* Whenever a generator is dropped it will drop all captured environment\n variables.\n\n### Generators as state machines\n\nIn the compiler, generators are currently compiled as state machines. Each\n`yield` expression will correspond to a different state that stores all live\nvariables over that suspension point. Resumption of a generator will dispatch on\nthe current state and then execute internally until a `yield` is reached, at\nwhich point all state is saved off in the generator and a value is returned.\n\nLet's take a look at an example to see what's going on here:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::Generator;\nuse std::pin::Pin;\n\nfn main() {\n let ret = \"foo\";\n let mut generator = move || {\n yield 1;\n return ret\n };\n\n Pin::new(&mut generator).resume(());\n Pin::new(&mut generator).resume(());\n}\n```\n\nThis generator literal will compile down to something similar to:\n\n```rust\n#![feature(arbitrary_self_types, generators, generator_trait)]\n\nuse std::ops::{Generator, GeneratorState};\nuse std::pin::Pin;\n\nfn main() {\n let ret = \"foo\";\n let mut generator = {\n enum __Generator {\n Start(&'static str),\n Yield1(&'static str),\n Done,\n }\n\n impl Generator for __Generator {\n type Yield = i32;\n type Return = &'static str;\n\n fn resume(mut self: Pin<&mut Self>, resume: ()) -> GeneratorState {\n use std::mem;\n match mem::replace(&mut *self, __Generator::Done) {\n __Generator::Start(s) => {\n *self = __Generator::Yield1(s);\n GeneratorState::Yielded(1)\n }\n\n __Generator::Yield1(s) => {\n *self = __Generator::Done;\n GeneratorState::Complete(s)\n }\n\n __Generator::Done => {\n panic!(\"generator resumed after completion\")\n }\n }\n }\n }\n\n __Generator::Start(ret)\n };\n\n Pin::new(&mut generator).resume(());\n Pin::new(&mut generator).resume(());\n}\n```\n\nNotably here we can see that the compiler is generating a fresh type,\n`__Generator` in this case. This type has a number of states (represented here\nas an `enum`) corresponding to each of the conceptual states of the generator.\nAt the beginning we're closing over our outer variable `foo` and then that\nvariable is also live over the `yield` point, so it's stored in both states.\n\nWhen the generator starts it'll immediately yield 1, but it saves off its state\njust before it does so indicating that it has reached the yield point.

The syntax isn't final, either. We may need an alternative syntax for Rust 2015 because, in Rust 2015, expressions like `[e; dyn(1)]` would be ambiguous. One possible alternative proposed in the RFC is `[e; n]`: if `n` captures one or more local variables, then it is considered as `[e; dyn n]`.\n\n## Advisory on stack usage\n\nIt's advised not to casually use the `#![feature(unsized_locals)]` feature. Typical use-cases are:\n\n- When you need a by-value trait objects.\n- When you really need a fast allocation of small temporary arrays.\n\nAnother pitfall is repetitive allocation and temporaries. Currently the compiler simply extends the stack frame every time it encounters an unsized assignment. So for example, the code\n\n```rust\n#![feature(unsized_locals)]\n\nfn main() {\n let x: Box<[i32]> = Box::new([1, 2, 3, 4, 5]);\n let _x = {{{{{{{{{{*x}}}}}}}}}};\n}\n```\n\nand the code\n\n```rust\n#![feature(unsized_locals)]\n\nfn main() {\n for _ in 0..10 {\n let x: Box<[i32]> = Box::new([1, 2, 3, 4, 5]);\n let _x = *x;\n }\n}\n```\n\nwill unnecessarily extend the stack frame.\n" } , LintCompletion { label : "or_patterns" , description : "# `or_patterns`\n\nThe tracking issue for this feature is: [#54883]\n\n[#54883]: https://github.com/rust-lang/rust/issues/54883\n\n------------------------\n\nThe `or_pattern` language feature allows `|` to be arbitrarily nested within\na pattern, for example, `Some(A(0) | B(1 | 2))` becomes a valid pattern.\n\n## Examples\n\n```rust,ignore\n#![feature(or_patterns)]\n\npub enum Foo {\n Bar,\n Baz,\n Quux,\n}\n\npub fn example(maybe_foo: Option) {\n match maybe_foo {\n Some(Foo::Bar | Foo::Baz) => {\n println!(\"The value contained `Bar` or `Baz`\");\n }\n Some(_) => {\n println!(\"The value did not contain `Bar` or `Baz`\");\n }\n None => {\n println!(\"The value was `None`\");\n }\n }\n}\n```\n" } , LintCompletion { label : "member_constraints" , description : "# `member_constraints`\n\nThe tracking issue for this feature is: [#61997]\n\n[#61997]: https://github.com/rust-lang/rust/issues/61997\n\n------------------------\n\nThe `member_constraints` feature gate lets you use `impl Trait` syntax with\nmultiple unrelated lifetime parameters.\n\nA simple example is:\n\n```rust\n#![feature(member_constraints)]\n\ntrait Trait<'a, 'b> { }\nimpl Trait<'_, '_> for T {}\n\nfn foo<'a, 'b>(x: &'a u32, y: &'b u32) -> impl Trait<'a, 'b> {\n (x, y)\n}\n\nfn main() { }\n```\n\nWithout the `member_constraints` feature gate, the above example is an\nerror because both `'a` and `'b` appear in the impl Trait bounds, but\nneither outlives the other.\n" } , LintCompletion { label : "optin_builtin_traits" , description : "# `optin_builtin_traits`\n\nThe tracking issue for this feature is [#13231] \n\n[#13231]: https://github.com/rust-lang/rust/issues/13231\n\n----\n\nThe `optin_builtin_traits` feature gate allows you to define auto traits.\n\nAuto traits, like [`Send`] or [`Sync`] in the standard library, are marker traits\nthat are automatically implemented for every type, unless the type, or a type it contains, \nhas explicitly opted out via a negative impl.

These automatic impls contain a where clause for each field\nof the form `T: AutoTrait`, where `T` is the type of the field and\n`AutoTrait` is the auto trait in question. As an example, consider the\nstruct `List` and the auto trait `Send`:\n\n```rust\nstruct List {\n data: T,\n next: Option>>,\n}\n```\n\nPresuming that there is no explicit impl of `Send` for `List`, the\ncompiler will supply an automatic impl of the form:\n\n```rust\nstruct List {\n data: T,\n next: Option>>,\n}\n\nunsafe impl Send for List\nwhere\n T: Send, // from the field `data`\n Option>>: Send, // from the field `next`\n{ }\n```\n\nExplicit impls may be either positive or negative. They take the form:\n\n```rust,ignore\nimpl<...> AutoTrait for StructName<..> { }\nimpl<...> !AutoTrait for StructName<..> { }\n```\n\n## Coinduction: Auto traits permit cyclic matching\n\nUnlike ordinary trait matching, auto traits are **coinductive**. This\nmeans, in short, that cycles which occur in trait matching are\nconsidered ok. As an example, consider the recursive struct `List`\nintroduced in the previous section. In attempting to determine whether\n`List: Send`, we would wind up in a cycle: to apply the impl, we must\nshow that `Option>: Send`, which will in turn require\n`Box: Send` and then finally `List: Send` again. Under ordinary\ntrait matching, this cycle would be an error, but for an auto trait it\nis considered a successful match.\n\n## Items\n\nAuto traits cannot have any trait items, such as methods or associated types. This ensures that we can generate default implementations.\n\n## Supertraits\n\nAuto traits cannot have supertraits.

The marker is the attribute `#[lang = \"...\"]` and there are\nvarious different values of `...`, i.e. various different 'lang\nitems'.\n\nFor example, `Box` pointers require two lang items, one for allocation\nand one for deallocation. A freestanding program that uses the `Box`\nsugar for dynamic allocations via `malloc` and `free`:\n\n```rust,ignore\n#![feature(lang_items, box_syntax, start, libc, core_intrinsics)]\n#![no_std]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\nextern crate libc;\n\n#[lang = \"owned_box\"]\npub struct Box(*mut T);\n\n#[lang = \"exchange_malloc\"]\nunsafe fn allocate(size: usize, _align: usize) -> *mut u8 {\n let p = libc::malloc(size as libc::size_t) as *mut u8;\n\n // Check if `malloc` failed:\n if p as usize == 0 {\n intrinsics::abort();\n }\n\n p\n}\n\n#[lang = \"box_free\"]\nunsafe fn box_free(ptr: *mut T) {\n libc::free(ptr as *mut libc::c_void)\n}\n\n#[start]\nfn main(_argc: isize, _argv: *const *const u8) -> isize {\n let _x = box 1;\n\n 0\n}\n\n#[lang = \"eh_personality\"] extern fn rust_eh_personality() {}\n#[lang = \"panic_impl\"] extern fn rust_begin_panic(info: &PanicInfo) -> ! { unsafe { intrinsics::abort() } }\n#[no_mangle] pub extern fn rust_eh_register_frames () {}\n#[no_mangle] pub extern fn rust_eh_unregister_frames () {}\n```\n\nNote the use of `abort`: the `exchange_malloc` lang item is assumed to\nreturn a valid pointer, and so needs to do the check internally.\n\nOther features provided by lang items include:\n\n- overloadable operators via traits: the traits corresponding to the\n `==`, `<`, dereferencing (`*`) and `+` (etc.) operators are all\n marked with lang items; those specific four are `eq`, `ord`,\n `deref`, and `add` respectively.\n- stack unwinding and general failure; the `eh_personality`,\n `panic` and `panic_bounds_checks` lang items.\n- the traits in `std::marker` used to indicate types of\n various kinds; lang items `send`, `sync` and `copy`.\n- the marker types and variance indicators found in\n `std::marker`; lang items `covariant_type`,\n `contravariant_lifetime`, etc.\n\nLang items are loaded lazily by the compiler; e.g. if one never uses\n`Box` then there is no need to define functions for `exchange_malloc`\nand `box_free`. `rustc` will emit an error when an item is needed\nbut not found in the current crate or any that it depends on.\n\nMost lang items are defined by `libcore`, but if you're trying to build\nan executable without the standard library, you'll run into the need\nfor lang items. The rest of this page focuses on this use-case, even though\nlang items are a bit broader than that.\n\n### Using libc\n\nIn order to build a `#[no_std]` executable we will need libc as a dependency.\nWe can specify this using our `Cargo.toml` file:\n\n```toml\n[dependencies]\nlibc = { version = \"0.2.14\", default-features = false }\n```\n\nNote that the default features have been disabled. This is a critical step -\n**the default features of libc include the standard library and so must be\ndisabled.**\n\n### Writing an executable without stdlib\n\nControlling the entry point is possible in two ways: the `#[start]` attribute,\nor overriding the default shim for the C `main` function with your own.\n\nThe function marked `#[start]` is passed the command line parameters\nin the same format as C:\n\n```rust,ignore\n#![feature(lang_items, core_intrinsics)]\n#![feature(start)]\n#![no_std]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\n// Pull in the system libc library for what crt0.o likely requires.\nextern crate libc;\n\n// Entry point for this program.\n#[start]\nfn start(_argc: isize, _argv: *const *const u8) -> isize {\n 0\n}\n\n// These functions are used by the compiler, but not\n// for a bare-bones hello world. These are normally\n// provided by libstd.\n#[lang = \"eh_personality\"]\n#[no_mangle]\npub extern fn rust_eh_personality() {\n}\n\n#[lang = \"panic_impl\"]\n#[no_mangle]\npub extern fn rust_begin_panic(info: &PanicInfo) -> ! {\n unsafe { intrinsics::abort() }\n}\n```\n\nTo override the compiler-inserted `main` shim, one has to disable it\nwith `#![no_main]` and then create the appropriate symbol with the\ncorrect ABI and the correct name, which requires overriding the\ncompiler's name mangling too:\n\n```rust,ignore\n#![feature(lang_items, core_intrinsics)]\n#![feature(start)]\n#![no_std]\n#![no_main]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\n// Pull in the system libc library for what crt0.o likely requires.\nextern crate libc;\n\n// Entry point for this program.\n#[no_mangle] // ensure that this symbol is called `main` in the output\npub extern fn main(_argc: i32, _argv: *const *const u8) -> i32 {\n 0\n}\n\n// These functions are used by the compiler, but not\n// for a bare-bones hello world.

You may observe this via linker error messages\nsuch as \"```undefined reference to `__rust_probestack'```\".\n\n## More about the language items\n\nThe compiler currently makes a few assumptions about symbols which are\navailable in the executable to call. Normally these functions are provided by\nthe standard library, but without it you must define your own. These symbols\nare called \"language items\", and they each have an internal name, and then a\nsignature that an implementation must conform to.\n\nThe first of these functions, `rust_eh_personality`, is used by the failure\nmechanisms of the compiler. This is often mapped to GCC's personality function\n(see the [libstd implementation][unwind] for more information), but crates\nwhich do not trigger a panic can be assured that this function is never\ncalled.

Negative impls are a commitment not to implement the given trait for the named types.\n\n## Orphan and overlap rules\n\nNegative impls must obey the same orphan rules as a positive impl. This implies you cannot add a negative impl for types defined in upstream crates and so forth.\n\nSimilarly, negative impls cannot overlap with positive impls, again using the same \"overlap\" check that we ordinarily use to determine if two impls overlap. (Note that positive impls typically cannot overlap with one another either, except as permitted by specialization.)\n\n## Interaction with auto traits\n\nDeclaring a negative impl `impl !SomeAutoTrait for SomeType` for an\nauto-trait serves two purposes:\n\n* as with any trait, it declares that `SomeType` will never implement `SomeAutoTrait`;\n* it disables the automatic `SomeType: SomeAutoTrait` impl that would otherwise have been generated.\n\nNote that, at present, there is no way to indicate that a given type\ndoes not implement an auto trait *but that it may do so in the\nfuture*. For ordinary types, this is done by simply not declaring any\nimpl at all, but that is not an option for auto traits. A workaround\nis that one could embed a marker type as one of the fields, where the\nmarker type is `!AutoTrait`.\n\n## Immediate uses\n\nNegative impls are used to declare that `&T: !DerefMut` and `&mut T: !Clone`, as required to fix the soundness of `Pin` described in [#66544](https://github.com/rust-lang/rust/issues/66544).\n\nThis serves two purposes:\n\n* For proving the correctness of unsafe code, we can use that impl as evidence that no `DerefMut` or `Clone` impl exists.\n* It prevents downstream crates from creating such impls.\n" } , LintCompletion { label : "abi_ptx" , description : "# `abi_ptx`\n\nThe tracking issue for this feature is: [#38788]\n\n[#38788]: https://github.com/rust-lang/rust/issues/38788\n\n------------------------\n\nWhen emitting PTX code, all vanilla Rust functions (`fn`) get translated to\n\"device\" functions.

This is\ngenerally unwanted unless you are building another plugin.\n\nThe usual practice is to put compiler plugins in their own crate, separate from\nany `macro_rules!` macros or ordinary Rust code meant to be used by consumers\nof a library.\n\n# Lint plugins\n\nPlugins can extend [Rust's lint\ninfrastructure](../../reference/attributes/diagnostics.md#lint-check-attributes) with\nadditional checks for code style, safety, etc. Now let's write a plugin\n[`lint-plugin-test.rs`](https://github.com/rust-lang/rust/blob/master/src/test/ui-fulldeps/auxiliary/lint-plugin-test.rs)\nthat warns about any item named `lintme`.\n\n```rust,ignore\n#![feature(plugin_registrar)]\n#![feature(box_syntax, rustc_private)]\n\nextern crate rustc_ast;\n\n// Load rustc as a plugin to get macros\nextern crate rustc_driver;\n#[macro_use]\nextern crate rustc_lint;\n#[macro_use]\nextern crate rustc_session;\n\nuse rustc_driver::plugin::Registry;\nuse rustc_lint::{EarlyContext, EarlyLintPass, LintArray, LintContext, LintPass};\nuse rustc_ast::ast;\ndeclare_lint!(TEST_LINT, Warn, \"Warn about items named 'lintme'\");\n\ndeclare_lint_pass!(Pass => [TEST_LINT]);\n\nimpl EarlyLintPass for Pass {\n fn check_item(&mut self, cx: &EarlyContext, it: &ast::Item) {\n if it.ident.name.as_str() == \"lintme\" {\n cx.lint(TEST_LINT, |lint| {\n lint.build(\"item is named 'lintme'\").set_span(it.span).emit()\n });\n }\n }\n}\n\n#[plugin_registrar]\npub fn plugin_registrar(reg: &mut Registry) {\n reg.lint_store.register_lints(&[&TEST_LINT]);\n reg.lint_store.register_early_pass(|| box Pass);\n}\n```\n\nThen code like\n\n```rust,ignore\n#![feature(plugin)]\n#![plugin(lint_plugin_test)]\n\nfn lintme() { }\n```\n\nwill produce a compiler warning:\n\n```txt\nfoo.rs:4:1: 4:16 warning: item is named 'lintme', #[warn(test_lint)] on by default\nfoo.rs:4 fn lintme() { }\n ^~~~~~~~~~~~~~~\n```\n\nThe components of a lint plugin are:\n\n* one or more `declare_lint!` invocations, which define static `Lint` structs;\n\n* a struct holding any state needed by the lint pass (here, none);\n\n* a `LintPass`\n implementation defining how to check each syntax element. A single\n `LintPass` may call `span_lint` for several different `Lint`s, but should\n register them all through the `get_lints` method.\n\nLint passes are syntax traversals, but they run at a late stage of compilation\nwhere type information is available. `rustc`'s [built-in\nlints](https://github.com/rust-lang/rust/blob/master/src/librustc_session/lint/builtin.rs)\nmostly use the same infrastructure as lint plugins, and provide examples of how\nto access type information.\n\nLints defined by plugins are controlled by the usual [attributes and compiler\nflags](../../reference/attributes/diagnostics.md#lint-check-attributes), e.g.\n`#[allow(test_lint)]` or `-A test-lint`. These identifiers are derived from the\nfirst argument to `declare_lint!`, with appropriate case and punctuation\nconversion.\n\nYou can run `rustc -W help foo.rs` to see a list of lints known to `rustc`,\nincluding those provided by plugins loaded by `foo.rs`.\n" } , LintCompletion { label : "concat_idents" , description : "# `concat_idents`\n\nThe tracking issue for this feature is: [#29599]\n\n[#29599]: https://github.com/rust-lang/rust/issues/29599\n\n------------------------\n\nThe `concat_idents` feature adds a macro for concatenating multiple identifiers\ninto one identifier.\n\n## Examples\n\n```rust\n#![feature(concat_idents)]\n\nfn main() {\n fn foobar() -> u32 { 23 }\n let f = concat_idents!(foo, bar);\n assert_eq!(f(), 23);\n}\n```" } , LintCompletion { label : "update_panic_count" , description : "# `update_panic_count`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "fn_traits" , description : "# `fn_traits`\n\nThe tracking issue for this feature is [#29625]\n\nSee Also: [`unboxed_closures`](../language-features/unboxed-closures.md)\n\n[#29625]: https://github.com/rust-lang/rust/issues/29625\n\n----\n\nThe `fn_traits` feature allows for implementation of the [`Fn*`] traits\nfor creating custom closure-like types.\n\n[`Fn*`]: https://doc.rust-lang.org/std/ops/trait.Fn.html\n\n```rust\n#![feature(unboxed_closures)]\n#![feature(fn_traits)]\n\nstruct Adder {\n a: u32\n}\n\nimpl FnOnce<(u32, )> for Adder {\n type Output = u32;\n extern \"rust-call\" fn call_once(self, b: (u32, )) -> Self::Output {\n self.a + b.0\n }\n}\n\nfn main() {\n let adder = Adder { a: 3 };\n assert_eq!(adder(2), 5);\n}\n```\n" } , LintCompletion { label : "try_trait" , description : "# `try_trait`\n\nThe tracking issue for this feature is: [#42327]\n\n[#42327]: https://github.com/rust-lang/rust/issues/42327\n\n------------------------\n\nThis introduces a new trait `Try` for extending the `?` operator to types\nother than `Result` (a part of [RFC 1859]).

The macro is a no-frills\ninterface to LLVM's concept of [module-level inline assembly]. That is,\nall caveats applicable to LLVM's module-level inline assembly apply\nto `global_asm!`.\n\n[module-level inline assembly]: http://llvm.org/docs/LangRef.html#module-level-inline-assembly\n\n`global_asm!` fills a role not currently satisfied by either `asm!`\nor `#[naked]` functions. The programmer has _all_ features of the\nassembler at their disposal. The linker will expect to resolve any\nsymbols defined in the inline assembly, modulo any symbols marked as\nexternal. It also means syntax for directives and assembly follow the\nconventions of the assembler in your toolchain.\n\nA simple usage looks like this:\n\n```rust,ignore\n# #![feature(global_asm)]\n# you also need relevant target_arch cfgs\nglobal_asm!(include_str!(\"something_neato.s\"));\n```\n\nAnd a more complicated usage looks like this:\n\n```rust,ignore\n# #![feature(global_asm)]\n# #![cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n\npub mod sally {\n global_asm!(r#\"\n .global foo\n foo:\n jmp baz\n \"#);\n\n #[no_mangle]\n pub unsafe extern \"C\" fn baz() {}\n}\n\n// the symbols `foo` and `bar` are global, no matter where\n// `global_asm!` was used.\nextern \"C\" {\n fn foo();\n fn bar();\n}\n\npub mod harry {\n global_asm!(r#\"\n .global bar\n bar:\n jmp quux\n \"#);\n\n #[no_mangle]\n pub unsafe extern \"C\" fn quux() {}\n}\n```\n\nYou may use `global_asm!` multiple times, anywhere in your crate, in\nwhatever way suits you. The effect is as if you concatenated all\nusages and placed the larger, single usage in the crate root.\n\n------------------------\n\nIf you don't need quite as much power and flexibility as\n`global_asm!` provides, and you don't mind restricting your inline\nassembly to `fn` bodies only, you might try the\n[asm](asm.md) feature instead.\n" } , LintCompletion { label : "sort_internals" , description : "# `sort_internals`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "test" , description : "# `test`\n\nThe tracking issue for this feature is: None.\n\n------------------------\n\nThe internals of the `test` crate are unstable, behind the `test` flag. The\nmost widely used part of the `test` crate are benchmark tests, which can test\nthe performance of your code. Let's make our `src/lib.rs` look like this\n(comments elided):\n\n```rust,ignore\n#![feature(test)]\n\nextern crate test;\n\npub fn add_two(a: i32) -> i32 {\n a + 2\n}\n\n#[cfg(test)]\nmod tests {\n use super::*;\n use test::Bencher;\n\n #[test]\n fn it_works() {\n assert_eq!(4, add_two(2));\n }\n\n #[bench]\n fn bench_add_two(b: &mut Bencher) {\n b.iter(|| add_two(2));\n }\n}\n```\n\nNote the `test` feature gate, which enables this unstable feature.\n\nWe've imported the `test` crate, which contains our benchmarking support.\nWe have a new function as well, with the `bench` attribute. Unlike regular\ntests, which take no arguments, benchmark tests take a `&mut Bencher`. This\n`Bencher` provides an `iter` method, which takes a closure. This closure\ncontains the code we'd like to benchmark.\n\nWe can run benchmark tests with `cargo bench`:\n\n```bash\n$ cargo bench\n Compiling adder v0.0.1 (file:///home/steve/tmp/adder)\n Running target/release/adder-91b3e234d4ed382a\n\nrunning 2 tests\ntest tests::it_works ... ignored\ntest tests::bench_add_two ... bench: 1 ns/iter (+/- 0)\n\ntest result: ok. 0 passed; 0 failed; 1 ignored; 1 measured\n```\n\nOur non-benchmark test was ignored. You may have noticed that `cargo bench`\ntakes a bit longer than `cargo test`. This is because Rust runs our benchmark\na number of times, and then takes the average. Because we're doing so little\nwork in this example, we have a `1 ns/iter (+/- 0)`, but this would show\nthe variance if there was one.\n\nAdvice on writing benchmarks:\n\n\n* Move setup code outside the `iter` loop; only put the part you want to measure inside\n* Make the code do \"the same thing\" on each iteration; do not accumulate or change state\n* Make the outer function idempotent too; the benchmark runner is likely to run\n it many times\n* Make the inner `iter` loop short and fast so benchmark runs are fast and the\n calibrator can adjust the run-length at fine resolution\n* Make the code in the `iter` loop do something simple, to assist in pinpointing\n performance improvements (or regressions)\n\n## Gotcha: optimizations\n\nThere's another tricky part to writing benchmarks: benchmarks compiled with\noptimizations activated can be dramatically changed by the optimizer so that\nthe benchmark is no longer benchmarking what one expects. For example, the\ncompiler might recognize that some calculation has no external effects and\nremove it entirely.\n\n```rust,ignore\n#![feature(test)]\n\nextern crate test;\nuse test::Bencher;\n\n#[bench]\nfn bench_xor_1000_ints(b: &mut Bencher) {\n b.iter(|| {\n (0..1000).fold(0, |old, new| old ^ new);\n });\n}\n```\n\ngives the following results\n\n```text\nrunning 1 test\ntest bench_xor_1000_ints ... bench: 0 ns/iter (+/- 0)\n\ntest result: ok. 0 passed; 0 failed; 0 ignored; 1 measured\n```\n\nThe benchmarking runner offers two ways to avoid this. Either, the closure that\nthe `iter` method receives can return an arbitrary value which forces the\noptimizer to consider the result used and ensures it cannot remove the\ncomputation entirely. This could be done for the example above by adjusting the\n`b.iter` call to\n\n```rust\n# struct X;\n# impl X { fn iter(&self, _: F) where F: FnMut() -> T {} } let b = X;\nb.iter(|| {\n // Note lack of `;` (could also use an explicit `return`).\n (0..1000).fold(0, |old, new| old ^ new)\n});\n```\n\nOr, the other option is to call the generic `test::black_box` function, which\nis an opaque \"black box\" to the optimizer and so forces it to consider any\nargument as used.\n\n```rust\n#![feature(test)]\n\nextern crate test;\n\n# fn main() {\n# struct X;\n# impl X { fn iter(&self, _: F) where F: FnMut() -> T {} } let b = X;\nb.iter(|| {\n let n = test::black_box(1000);\n\n (0..n).fold(0, |a, b| a ^ b)\n})\n# }\n```\n\nNeither of these read or modify the value, and are very cheap for small values.\nLarger values can be passed indirectly to reduce overhead (e.g.\n`black_box(&huge_struct)`).\n\nPerforming either of the above changes gives the following benchmarking results\n\n```text\nrunning 1 test\ntest bench_xor_1000_ints ... bench: 131 ns/iter (+/- 3)\n\ntest result: ok. 0 passed; 0 failed; 0 ignored; 1 measured\n```\n\nHowever, the optimizer can still modify a testcase in an undesirable manner\neven when using either of the above.\n" } , LintCompletion { label : "windows_stdio" , description : "# `windows_stdio`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "allocator_api" , description : "# `allocator_api`\n\nThe tracking issue for this feature is [#32838]\n\n[#32838]: https://github.com/rust-lang/rust/issues/32838\n\n------------------------\n\nSometimes you want the memory for one collection to use a different\nallocator than the memory for another collection.

Rust supports using inline\nassembly to do this via the `asm!` macro.\n\n# Guide-level explanation\n[guide-level-explanation]: #guide-level-explanation\n\nRust provides support for inline assembly via the `asm!` macro.\nIt can be used to embed handwritten assembly in the assembly output generated by the compiler.\nGenerally this should not be necessary, but might be where the required performance or timing\ncannot be otherwise achieved. Accessing low level hardware primitives, e.g. in kernel code, may also demand this functionality.\n\n> **Note**: the examples here are given in x86/x86-64 assembly, but ARM, AArch64 and RISC-V are also supported.\n\n## Basic usage\n\nLet us start with the simplest possible example:\n\n```rust,allow_fail\n# #![feature(asm)]\nunsafe {\n asm!(\"nop\");\n}\n```\n\nThis will insert a NOP (no operation) instruction into the assembly generated by the compiler.\nNote that all `asm!` invocations have to be inside an `unsafe` block, as they could insert\narbitrary instructions and break various invariants. The instructions to be inserted are listed\nin the first argument of the `asm!` macro as a string literal.\n\n## Inputs and outputs\n\nNow inserting an instruction that does nothing is rather boring. Let us do something that\nactually acts on data:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet x: u64;\nunsafe {\n asm!(\"mov {}, 5\", out(reg) x);\n}\nassert_eq!(x, 5);\n```\n\nThis will write the value `5` into the `u64` variable `x`.\nYou can see that the string literal we use to specify instructions is actually a template string.\nIt is governed by the same rules as Rust [format strings][format-syntax].\nThe arguments that are inserted into the template however look a bit different then you may\nbe familiar with. First we need to specify if the variable is an input or an output of the\ninline assembly. In this case it is an output. We declared this by writing `out`.\nWe also need to specify in what kind of register the assembly expects the variable.\nIn this case we put it in an arbitrary general purpose register by specifying `reg`.\nThe compiler will choose an appropriate register to insert into\nthe template and will read the variable from there after the inline assembly finishes executing.\n\nLet us see another example that also uses an input:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet i: u64 = 3;\nlet o: u64;\nunsafe {\n asm!(\n \"mov {0}, {1}\",\n \"add {0}, {number}\",\n out(reg) o,\n in(reg) i,\n number = const 5,\n );\n}\nassert_eq!(o, 8);\n```\n\nThis will add `5` to the input in variable `i` and write the result to variable `o`.\nThe particular way this assembly does this is first copying the value from `i` to the output,\nand then adding `5` to it.\n\nThe example shows a few things:\n\nFirst, we can see that `asm!` allows multiple template string arguments; each\none is treated as a separate line of assembly code, as if they were all joined\ntogether with newlines between them. This makes it easy to format assembly\ncode.\n\nSecond, we can see that inputs are declared by writing `in` instead of `out`.\n\nThird, one of our operands has a type we haven't seen yet, `const`.\nThis tells the compiler to expand this argument to value directly inside the assembly template.\nThis is only possible for constants and literals.\n\nFourth, we can see that we can specify an argument number, or name as in any format string.\nFor inline assembly templates this is particularly useful as arguments are often used more than once.\nFor more complex inline assembly using this facility is generally recommended, as it improves\nreadability, and allows reordering instructions without changing the argument order.\n\nWe can further refine the above example to avoid the `mov` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut x: u64 = 3;\nunsafe {\n asm!(\"add {0}, {number}\", inout(reg) x, number = const 5);\n}\nassert_eq!(x, 8);\n```\n\nWe can see that `inout` is used to specify an argument that is both input and output.\nThis is different from specifying an input and output separately in that it is guaranteed to assign both to the same register.\n\nIt is also possible to specify different variables for the input and output parts of an `inout` operand:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet x: u64 = 3;\nlet y: u64;\nunsafe {\n asm!(\"add {0}, {number}\", inout(reg) x => y, number = const 5);\n}\nassert_eq!(y, 8);\n```\n\n## Late output operands\n\nThe Rust compiler is conservative with its allocation of operands. It is assumed that an `out`\ncan be written at any time, and can therefore not share its location with any other argument.\nHowever, to guarantee optimal performance it is important to use as few registers as possible,\nso they won't have to be saved and reloaded around the inline assembly block.\nTo achieve this Rust provides a `lateout` specifier. This can be used on any output that is\nwritten only after all inputs have been consumed.\nThere is also a `inlateout` variant of this specifier.\n\nHere is an example where `inlateout` *cannot* be used:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nlet c: u64 = 4;\nunsafe {\n asm!(\n \"add {0}, {1}\",\n \"add {0}, {2}\",\n inout(reg) a,\n in(reg) b,\n in(reg) c,\n );\n}\nassert_eq!(a, 12);\n```\n\nHere the compiler is free to allocate the same register for inputs `b` and `c` since it knows they have the same value. However it must allocate a separate register for `a` since it uses `inout` and not `inlateout`. If `inlateout` was used, then `a` and `c` could be allocated to the same register, in which case the first instruction to overwrite the value of `c` and cause the assembly code to produce the wrong result.\n\nHowever the following example can use `inlateout` since the output is only modified after all input registers have been read:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nunsafe {\n asm!(\"add {0}, {1}\", inlateout(reg) a, in(reg) b);\n}\nassert_eq!(a, 8);\n```\n\nAs you can see, this assembly fragment will still work correctly if `a` and `b` are assigned to the same register.\n\n## Explicit register operands\n\nSome instructions require that the operands be in a specific register.\nTherefore, Rust inline assembly provides some more specific constraint specifiers.\nWhile `reg` is generally available on any architecture, these are highly architecture specific. E.g. for x86 the general purpose registers `eax`, `ebx`, `ecx`, `edx`, `ebp`, `esi`, and `edi`\namong others can be addressed by their name.\n\n```rust,allow_fail,no_run\n# #![feature(asm)]\nlet cmd = 0xd1;\nunsafe {\n asm!(\"out 0x64, eax\", in(\"eax\") cmd);\n}\n```\n\nIn this example we call the `out` instruction to output the content of the `cmd` variable\nto port `0x64`. Since the `out` instruction only accepts `eax` (and its sub registers) as operand\nwe had to use the `eax` constraint specifier.\n\nNote that unlike other operand types, explicit register operands cannot be used in the template string: you can't use `{}` and should write the register name directly instead. Also, they must appear at the end of the operand list after all other operand types.\n\nConsider this example which uses the x86 `mul` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nfn mul(a: u64, b: u64) -> u128 {\n let lo: u64;\n let hi: u64;\n\n unsafe {\n asm!(\n // The x86 mul instruction takes rax as an implicit input and writes\n // the 128-bit result of the multiplication to rax:rdx.\n \"mul {}\",\n in(reg) a,\n inlateout(\"rax\") b => lo,\n lateout(\"rdx\") hi\n );\n }\n\n ((hi as u128) << 64) + lo as u128\n}\n```\n\nThis uses the `mul` instruction to multiply two 64-bit inputs with a 128-bit result.\nThe only explicit operand is a register, that we fill from the variable `a`.\nThe second operand is implicit, and must be the `rax` register, which we fill from the variable `b`.\nThe lower 64 bits of the result are stored in `rax` from which we fill the variable `lo`.\nThe higher 64 bits are stored in `rdx` from which we fill the variable `hi`.\n\n## Clobbered registers\n\nIn many cases inline assembly will modify state that is not needed as an output.\nUsually this is either because we have to use a scratch register in the assembly,\nor instructions modify state that we don't need to further examine.\nThis state is generally referred to as being \"clobbered\".\nWe need to tell the compiler about this since it may need to save and restore this state\naround the inline assembly block.\n\n```rust,allow_fail\n# #![feature(asm)]\nlet ebx: u32;\nlet ecx: u32;\n\nunsafe {\n asm!(\n \"cpuid\",\n // EAX 4 selects the \"Deterministic Cache Parameters\" CPUID leaf\n inout(\"eax\") 4 => _,\n // ECX 0 selects the L0 cache information.\n inout(\"ecx\") 0 => ecx,\n lateout(\"ebx\") ebx,\n lateout(\"edx\") _,\n );\n}\n\nprintln!(\n \"L1 Cache: {}\",\n ((ebx >> 22) + 1) * (((ebx >> 12) & 0x3ff) + 1) * ((ebx & 0xfff) + 1) * (ecx + 1)\n);\n```\n\nIn the example above we use the `cpuid` instruction to get the L1 cache size.\nThis instruction writes to `eax`, `ebx`, `ecx`, and `edx`, but for the cache size we only care about the contents of `ebx` and `ecx`.\n\nHowever we still need to tell the compiler that `eax` and `edx` have been modified so that it can save any values that were in these registers before the asm. This is done by declaring these as outputs but with `_` instead of a variable name, which indicates that the output value is to be discarded.\n\nThis can also be used with a general register class (e.g. `reg`) to obtain a scratch register for use inside the asm code:\n\n```rust,allow_fail\n# #![feature(asm)]\n// Multiply x by 6 using shifts and adds\nlet mut x: u64 = 4;\nunsafe {\n asm!(\n \"mov {tmp}, {x}\",\n \"shl {tmp}, 1\",\n \"shl {x}, 2\",\n \"add {x}, {tmp}\",\n x = inout(reg) x,\n tmp = out(reg) _,\n );\n}\nassert_eq!(x, 4 * 6);\n```\n\n## Symbol operands\n\nA special operand type, `sym`, allows you to use the symbol name of a `fn` or `static` in inline assembly code.\nThis allows you to call a function or access a global variable without needing to keep its address in a register.\n\n```rust,allow_fail\n# #![feature(asm)]\nextern \"C\" fn foo(arg: i32) {\n println!(\"arg = {}\", arg);\n}\n\nfn call_foo(arg: i32) {\n unsafe {\n asm!(\n \"call {}\",\n sym foo,\n // 1st argument in rdi, which is caller-saved\n inout(\"rdi\") arg => _,\n // All caller-saved registers must be marked as clobberred\n out(\"rax\") _, out(\"rcx\") _, out(\"rdx\") _, out(\"rsi\") _,\n out(\"r8\") _, out(\"r9\") _, out(\"r10\") _, out(\"r11\") _,\n out(\"xmm0\") _, out(\"xmm1\") _, out(\"xmm2\") _, out(\"xmm3\") _,\n out(\"xmm4\") _, out(\"xmm5\") _, out(\"xmm6\") _, out(\"xmm7\") _,\n out(\"xmm8\") _, out(\"xmm9\") _, out(\"xmm10\") _, out(\"xmm11\") _,\n out(\"xmm12\") _, out(\"xmm13\") _, out(\"xmm14\") _, out(\"xmm15\") _,\n )\n }\n}\n```\n\nNote that the `fn` or `static` item does not need to be public or `#[no_mangle]`:\nthe compiler will automatically insert the appropriate mangled symbol name into the assembly code.\n\n## Register template modifiers\n\nIn some cases, fine control is needed over the way a register name is formatted when inserted into the template string. This is needed when an architecture's assembly language has several names for the same register, each typically being a \"view\" over a subset of the register (e.g. the low 32 bits of a 64-bit register).\n\nBy default the compiler will always choose the name that refers to the full register size (e.g. `rax` on x86-64, `eax` on x86, etc).\n\nThis default can be overriden by using modifiers on the template string operands, just like you would with format strings:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut x: u16 = 0xab;\n\nunsafe {\n asm!(\"mov {0:h}, {0:l}\", inout(reg_abcd) x);\n}\n\nassert_eq!(x, 0xabab);\n```\n\nIn this example, we use the `reg_abcd` register class to restrict the register allocator to the 4 legacy x86 register (`ax`, `bx`, `cx`, `dx`) of which the first two bytes can be addressed independently.\n\nLet us assume that the register allocator has chosen to allocate `x` in the `ax` register.\nThe `h` modifier will emit the register name for the high byte of that register and the `l` modifier will emit the register name for the low byte. The asm code will therefore be expanded as `mov ah, al` which copies the low byte of the value into the high byte.\n\nIf you use a smaller data type (e.g. `u16`) with an operand and forget the use template modifiers, the compiler will emit a warning and suggest the correct modifier to use.\n\n## Options\n\nBy default, an inline assembly block is treated the same way as an external FFI function call with a custom calling convention: it may read/write memory, have observable side effects, etc. However in many cases, it is desirable to give the compiler more information about what the assembly code is actually doing so that it can optimize better.\n\nLet's take our previous example of an `add` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nunsafe {\n asm!(\n \"add {0}, {1}\",\n inlateout(reg) a, in(reg) b,\n options(pure, nomem, nostack),\n );\n}\nassert_eq!(a, 8);\n```\n\nOptions can be provided as an optional final argument to the `asm!` macro. We specified three options here:\n- `pure` means that the asm code has no observable side effects and that its output depends only on its inputs. This allows the compiler optimizer to call the inline asm fewer times or even eliminate it entirely.\n- `nomem` means that the asm code does not read or write to memory. By default the compiler will assume that inline assembly can read or write any memory address that is accessible to it (e.g. through a pointer passed as an operand, or a global).\n- `nostack` means that the asm code does not push any data onto the stack. This allows the compiler to use optimizations such as the stack red zone on x86-64 to avoid stack pointer adjustments.\n\nThese allow the compiler to better optimize code using `asm!`, for example by eliminating pure `asm!` blocks whose outputs are not needed.\n\nSee the reference for the full list of available options and their effects.\n\n# Reference-level explanation\n[reference-level-explanation]: #reference-level-explanation\n\nInline assembler is implemented as an unsafe macro `asm!()`.\nThe first argument to this macro is a template string literal used to build the final assembly.\nThe following arguments specify input and output operands.\nWhen required, options are specified as the final argument.\n\nThe following ABNF specifies the general syntax:\n\n```ignore\ndir_spec := \"in\" / \"out\" / \"lateout\" / \"inout\" / \"inlateout\"\nreg_spec := / \"\"\noperand_expr := expr / \"_\" / expr \"=>\" expr / expr \"=>\" \"_\"\nreg_operand := dir_spec \"(\" reg_spec \")\" operand_expr\noperand := reg_operand / \"const\" const_expr / \"sym\" path\noption := \"pure\" / \"nomem\" / \"readonly\" / \"preserves_flags\" / \"noreturn\" / \"att_syntax\"\noptions := \"options(\" option *[\",\" option] [\",\"] \")\"\nasm := \"asm!(\" format_string *(\",\" format_string) *(\",\" [ident \"=\"] operand) [\",\" options] [\",\"] \")\"\n```\n\nThe macro will initially be supported only on ARM, AArch64, Hexagon, x86, x86-64 and RISC-V targets. Support for more targets may be added in the future. The compiler will emit an error if `asm!` is used on an unsupported target.\n\n[format-syntax]: https://doc.rust-lang.org/std/fmt/#syntax\n\n## Template string arguments\n\nThe assembler template uses the same syntax as [format strings][format-syntax] (i.e. placeholders are specified by curly braces). The corresponding arguments are accessed in order, by index, or by name. However, implicit named arguments (introduced by [RFC #2795][rfc-2795]) are not supported.\n\nAn `asm!` invocation may have one or more template string arguments; an `asm!` with multiple template string arguments is treated as if all the strings were concatenated with a `\\n` between them. The expected usage is for each template string argument to correspond to a line of assembly code. All template string arguments must appear before any other arguments.\n\nAs with format strings, named arguments must appear after positional arguments. Explicit register operands must appear at the end of the operand list, after named arguments if any.\n\nExplicit register operands cannot be used by placeholders in the template string. All other named and positional operands must appear at least once in the template string, otherwise a compiler error is generated.\n\nThe exact assembly code syntax is target-specific and opaque to the compiler except for the way operands are substituted into the template string to form the code passed to the assembler.\n\nThe 5 targets specified in this RFC (x86, ARM, AArch64, RISC-V, Hexagon) all use the assembly code syntax of the GNU assembler (GAS). On x86, the `.intel_syntax noprefix` mode of GAS is used by default. On ARM, the `.syntax unified` mode is used. These targets impose an additional restriction on the assembly code: any assembler state (e.g. the current section which can be changed with `.section`) must be restored to its original value at the end of the asm string. Assembly code that does not conform to the GAS syntax will result in assembler-specific behavior.\n\n[rfc-2795]: https://github.com/rust-lang/rfcs/pull/2795\n\n## Operand type\n\nSeveral types of operands are supported:\n\n* `in() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain the value of `` at the start of the asm code.\n - The allocated register must contain the same value at the end of the asm code (except if a `lateout` is allocated to the same register).\n* `out() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain an undefined value at the start of the asm code.\n - `` must be a (possibly uninitialized) place expression, to which the contents of the allocated register is written to at the end of the asm code.\n - An underscore (`_`) may be specified instead of an expression, which will cause the contents of the register to be discarded at the end of the asm code (effectively acting as a clobber).\n* `lateout() `\n - Identical to `out` except that the register allocator can reuse a register allocated to an `in`.\n - You should only write to the register after all inputs are read, otherwise you may clobber an input.\n* `inout() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain the value of `` at the start of the asm code.\n - `` must be a mutable initialized place expression, to which the contents of the allocated register is written to at the end of the asm code.\n* `inout() => `\n - Same as `inout` except that the initial value of the register is taken from the value of ``.\n - `` must be a (possibly uninitialized) place expression, to which the contents of the allocated register is written to at the end of the asm code.\n - An underscore (`_`) may be specified instead of an expression for ``, which will cause the contents of the register to be discarded at the end of the asm code (effectively acting as a clobber).\n - `` and `` may have different types.\n* `inlateout() ` / `inlateout() => `\n - Identical to `inout` except that the register allocator can reuse a register allocated to an `in` (this can happen if the compiler knows the `in` has the same initial value as the `inlateout`).\n - You should only write to the register after all inputs are read, otherwise you may clobber an input.\n* `const `\n - `` must be an integer or floating-point constant expression.\n - The value of the expression is formatted as a string and substituted directly into the asm template string.\n* `sym `\n - `` must refer to a `fn` or `static`.\n - A mangled symbol name referring to the item is substituted into the asm template string.\n - The substituted string does not include any modifiers (e.g. GOT, PLT, relocations, etc).\n - `` is allowed to point to a `#[thread_local]` static, in which case the asm code can combine the symbol with relocations (e.g. `@plt`, `@TPOFF`) to read from thread-local data.\n\nOperand expressions are evaluated from left to right, just like function call arguments. After the `asm!` has executed, outputs are written to in left to right order. This is significant if two outputs point to the same place: that place will contain the value of the rightmost output.\n\n## Register operands\n\nInput and output operands can be specified either as an explicit register or as a register class from which the register allocator can select a register. Explicit registers are specified as string literals (e.g. `\"eax\"`) while register classes are specified as identifiers (e.g. `reg`). Using string literals for register names enables support for architectures that use special characters in register names, such as MIPS (`$0`, `$1`, etc).\n\nNote that explicit registers treat register aliases (e.g. `r14` vs `lr` on ARM) and smaller views of a register (e.g. `eax` vs `rax`) as equivalent to the base register. It is a compile-time error to use the same explicit register for two input operands or two output operands. Additionally, it is also a compile-time error to use overlapping registers (e.g. ARM VFP) in input operands or in output operands.\n\nOnly the following types are allowed as operands for inline assembly:\n- Integers (signed and unsigned)\n- Floating-point numbers\n- Pointers (thin only)\n- Function pointers\n- SIMD vectors (structs defined with `#[repr(simd)]` and which implement `Copy`). This includes architecture-specific vector types defined in `std::arch` such as `__m128` (x86) or `int8x16_t` (ARM).\n\nHere is the list of currently supported register classes:\n\n| Architecture | Register class | Registers | LLVM constraint code |\n| ------------ | -------------- | --------- | -------------------- |\n| x86 | `reg` | `ax`, `bx`, `cx`, `dx`, `si`, `di`, `r[8-15]` (x86-64 only) | `r` |\n| x86 | `reg_abcd` | `ax`, `bx`, `cx`, `dx` | `Q` |\n| x86-32 | `reg_byte` | `al`, `bl`, `cl`, `dl`, `ah`, `bh`, `ch`, `dh` | `q` |\n| x86-64 | `reg_byte` | `al`, `bl`, `cl`, `dl`, `sil`, `dil`, `r[8-15]b`, `ah`\\*, `bh`\\*, `ch`\\*, `dh`\\* | `q` |\n| x86 | `xmm_reg` | `xmm[0-7]` (x86) `xmm[0-15]` (x86-64) | `x` |\n| x86 | `ymm_reg` | `ymm[0-7]` (x86) `ymm[0-15]` (x86-64) | `x` |\n| x86 | `zmm_reg` | `zmm[0-7]` (x86) `zmm[0-31]` (x86-64) | `v` |\n| x86 | `kreg` | `k[1-7]` | `Yk` |\n| AArch64 | `reg` | `x[0-28]`, `x30` | `r` |\n| AArch64 | `vreg` | `v[0-31]` | `w` |\n| AArch64 | `vreg_low16` | `v[0-15]` | `x` |\n| ARM | `reg` | `r[0-5]` `r7`\\*, `r[8-10]`, `r11`\\*, `r12`, `r14` | `r` |\n| ARM (Thumb) | `reg_thumb` | `r[0-r7]` | `l` |\n| ARM (ARM) | `reg_thumb` | `r[0-r10]`, `r12`, `r14` | `l` |\n| ARM | `sreg` | `s[0-31]` | `t` |\n| ARM | `sreg_low16` | `s[0-15]` | `x` |\n| ARM | `dreg` | `d[0-31]` | `w` |\n| ARM | `dreg_low16` | `d[0-15]` | `t` |\n| ARM | `dreg_low8` | `d[0-8]` | `x` |\n| ARM | `qreg` | `q[0-15]` | `w` |\n| ARM | `qreg_low8` | `q[0-7]` | `t` |\n| ARM | `qreg_low4` | `q[0-3]` | `x` |\n| NVPTX | `reg16` | None\\* | `h` |\n| NVPTX | `reg32` | None\\* | `r` |\n| NVPTX | `reg64` | None\\* | `l` |\n| RISC-V | `reg` | `x1`, `x[5-7]`, `x[9-15]`, `x[16-31]` (non-RV32E) | `r` |\n| RISC-V | `freg` | `f[0-31]` | `f` |\n| Hexagon | `reg` | `r[0-28]` | `r` |\n\n> **Note**: On x86 we treat `reg_byte` differently from `reg` because the compiler can allocate `al` and `ah` separately whereas `reg` reserves the whole register.\n>\n> Note #2: On x86-64 the high byte registers (e.g. `ah`) are only available when used as an explicit register. Specifying the `reg_byte` register class for an operand will always allocate a low byte register.\n>\n> Note #3: NVPTX doesn't have a fixed register set, so named registers are not supported.\n>\n> Note #4: On ARM the frame pointer is either `r7` or `r11` depending on the platform.\n\nAdditional register classes may be added in the future based on demand (e.g. MMX, x87, etc).\n\nEach register class has constraints on which value types they can be used with. This is necessary because the way a value is loaded into a register depends on its type. For example, on big-endian systems, loading a `i32x4` and a `i8x16` into a SIMD register may result in different register contents even if the byte-wise memory representation of both values is identical. The availability of supported types for a particular register class may depend on what target features are currently enabled.\n\n| Architecture | Register class | Target feature | Allowed types |\n| ------------ | -------------- | -------------- | ------------- |\n| x86-32 | `reg` | None | `i16`, `i32`, `f32` |\n| x86-64 | `reg` | None | `i16`, `i32`, `f32`, `i64`, `f64` |\n| x86 | `reg_byte` | None | `i8` |\n| x86 | `xmm_reg` | `sse` | `i32`, `f32`, `i64`, `f64`,

The only exception is the `freg` register class on RISC-V where `f32` values are NaN-boxed in a `f64` as required by the RISC-V architecture.\n\nWhen separate input and output expressions are specified for an `inout` operand, both expressions must have the same type. The only exception is if both operands are pointers or integers, in which case they are only required to have the same size. This restriction exists because the register allocators in LLVM and GCC sometimes cannot handle tied operands with different types.\n\n## Register names\n\nSome registers have multiple names.

The frame pointer cannot be used as an input or output. |\n| ARM | `r6` | `r6` is used internally by LLVM as a base pointer and therefore cannot be used as an input or output. |\n| x86 | `k0` | This is a constant zero register which can't be modified. |\n| x86 | `ip` | This is the program counter, not a real register. |\n| x86 | `mm[0-7]` | MMX registers are not currently supported (but may be in the future). |\n| x86 | `st([0-7])` | x87 registers are not currently supported (but may be in the future). |\n| AArch64 | `xzr` | This is a constant zero register which can't be modified. |\n| ARM | `pc` | This is the program counter, not a real register. |\n| RISC-V | `x0` | This is a constant zero register which can't be modified. |\n| RISC-V | `gp`, `tp` | These registers are reserved and cannot be used as inputs or outputs. |\n| Hexagon | `lr` | This is the link register which cannot be used as an input or output. |\n\n## Template modifiers\n\nThe placeholders can be augmented by modifiers which are specified after the `:` in the curly braces. These modifiers do not affect register allocation, but change the way operands are formatted when inserted into the template string. Only one modifier is allowed per template placeholder.\n\nThe supported modifiers are a subset of LLVM's (and GCC's) [asm template argument modifiers][llvm-argmod], but do not use the same letter codes.\n\n| Architecture | Register class | Modifier | Example output | LLVM modifier |\n| ------------ | -------------- | -------- | -------------- | ------------- |\n| x86-32 | `reg` | None | `eax` | `k` |\n| x86-64 | `reg` | None | `rax` | `q` |\n| x86-32 | `reg_abcd` | `l` | `al` | `b` |\n| x86-64 | `reg` | `l` | `al` | `b` |\n| x86 | `reg_abcd` | `h` | `ah` | `h` |\n| x86 | `reg` | `x` | `ax` | `w` |\n| x86 | `reg` | `e` | `eax` | `k` |\n| x86-64 | `reg` | `r` | `rax` | `q` |\n| x86 | `reg_byte` | None | `al` / `ah` | None |\n| x86 | `xmm_reg` | None | `xmm0` | `x` |\n| x86 | `ymm_reg` | None | `ymm0` | `t` |\n| x86 | `zmm_reg` | None | `zmm0` | `g` |\n| x86 | `*mm_reg` | `x` | `xmm0` | `x` |\n| x86 | `*mm_reg` | `y` | `ymm0` | `t` |\n| x86 | `*mm_reg` | `z` | `zmm0` | `g` |\n| x86 | `kreg` | None | `k1` | None |\n| AArch64 | `reg` | None | `x0` | `x` |\n| AArch64 | `reg` | `w` | `w0` | `w` |\n| AArch64 | `reg` | `x` | `x0` | `x` |\n| AArch64 | `vreg` | None | `v0` | None |\n| AArch64 | `vreg` | `v` | `v0` | None |\n| AArch64 | `vreg` | `b` | `b0` | `b` |\n| AArch64 | `vreg` | `h` | `h0` | `h` |\n| AArch64 | `vreg` | `s` | `s0` | `s` |\n| AArch64 | `vreg` | `d` | `d0` | `d` |\n| AArch64 | `vreg` | `q` | `q0` | `q` |\n| ARM | `reg` | None | `r0` | None |\n| ARM | `sreg` | None | `s0` | None |\n| ARM | `dreg` | None | `d0` | `P` |\n| ARM | `qreg` | None | `q0` | `q` |\n| ARM | `qreg` | `e` / `f` | `d0` / `d1` | `e` / `f` |\n| NVPTX | `reg16` | None | `rs0` | None |\n| NVPTX | `reg32` | None | `r0` | None |\n| NVPTX | `reg64` | None | `rd0` | None |\n| RISC-V | `reg` | None | `x1` | None |\n| RISC-V | `freg` | None | `f0` | None |\n| Hexagon | `reg` | None | `r0` | None |\n\n> Notes:\n> - on ARM `e` / `f`: this prints the low or high doubleword register name of a NEON quad (128-bit) register.\n> - on x86: our behavior for `reg` with no modifiers differs from what GCC does. GCC will infer the modifier based on the operand value type, while we default to the full register size.\n> - on x86 `xmm_reg`: the `x`, `t` and `g` LLVM modifiers are not yet implemented in LLVM (they are supported by GCC only), but this should be a simple change.\n\nAs stated in the previous section, passing an input value smaller than the register width will result in the upper bits of the register containing undefined values. This is not a problem if the inline asm only accesses the lower bits of the register, which can be done by using a template modifier to use a subregister name in the asm code (e.g. `ax` instead of `rax`). Since this an easy pitfall, the compiler will suggest a template modifier to use where appropriate given the input type. If all references to an operand already have modifiers then the warning is suppressed for that operand.\n\n[llvm-argmod]: http://llvm.org/docs/LangRef.html#asm-template-argument-modifiers\n\n## Options\n\nFlags are used to further influence the behavior of the inline assembly block.\nCurrently the following options are defined:\n- `pure`: The `asm` block has no side effects, and its outputs depend only on its direct inputs (i.e. the values themselves, not what they point to) or values read from memory (unless the `nomem` options is also set). This allows the compiler to execute the `asm` block fewer times than specified in the program (e.g. by hoisting it out of a loop) or even eliminate it entirely if the outputs are not used.\n- `nomem`: The `asm` blocks does not read or write to any memory. This allows the compiler to cache the values of modified global variables in registers across the `asm` block since it knows that they are not read or written to by the `asm`.\n- `readonly`: The `asm` block does not write to any memory. This allows the compiler to cache the values of unmodified global variables in registers across the `asm` block since it knows that they are not written to by the `asm`.\n- `preserves_flags`: The `asm` block does not modify the flags register (defined in the rules below). This allows the compiler to avoid recomputing the condition flags after the `asm` block.\n- `noreturn`: The `asm` block never returns, and its return type is defined as `!` (never). Behavior is undefined if execution falls through past the end of the asm code. A `noreturn` asm block behaves just like a function which doesn't return; notably, local variables in scope are not dropped before it is invoked.\n- `nostack`: The `asm` block does not push data to the stack, or write to the stack red-zone (if supported by the target). If this option is *not* used then the stack pointer is guaranteed to be suitably aligned (according to the target ABI) for a function call.\n- `att_syntax`: This option is only valid on x86, and causes the assembler to use the `.att_syntax prefix` mode of the GNU assembler. Register operands are substituted in with a leading `%`.\n\nThe compiler performs some additional checks on options:\n- The `nomem` and `readonly` options are mutually exclusive: it is a compile-time error to specify both.\n- The `pure` option must be combined with either the `nomem` or `readonly` options, otherwise a compile-time error is emitted.\n- It is a compile-time error to specify `pure` on an asm block with no outputs or only discarded outputs (`_`).\n- It is a compile-time error to specify `noreturn` on an asm block with outputs.\n\n## Rules for inline assembly\n\n- Any registers not specified as inputs will contain an undefined value on entry to the asm block.\n - An \"undefined value\" in the context of inline assembly means that the register can (non-deterministically) have any one of the possible values allowed by the architecture. Notably it is not the same as an LLVM `undef` which can have a different value every time you read it (since such a concept does not exist in assembly code).\n- Any registers not specified as outputs must have the same value upon exiting the asm block as they had on entry, otherwise behavior is undefined.\n - This only applies to registers which can be specified as an input or output. Other registers follow target-specific rules.\n - Note that a `lateout` may be allocated to the same register as an `in`, in which case this rule does not apply. Code should not rely on this however since it depends on the results of register allocation.\n- Behavior is undefined if execution unwinds out of an asm block.\n - This also applies if the assembly code calls a function which then unwinds.\n- The set of memory locations that assembly code is allowed the read and write are the same as those allowed for an FFI function.\n - Refer to the unsafe code guidelines for the exact rules.\n - If the `readonly` option is set, then only memory reads are allowed.\n - If the `nomem` option is set then no reads or writes to memory are allowed.\n - These rules do not apply to memory which is private to the asm code, such as stack space allocated within the asm block.\n- The compiler cannot assume that the instructions in the asm are the ones that will actually end up executed.\n - This effectively means that the compiler must treat the `asm!` as a black box and only take the interface specification into account, not the instructions themselves.\n - Runtime code patching is allowed, via target-specific mechanisms (outside the scope of this RFC).\n- Unless the `nostack` option is set, asm code is allowed to use stack space below the stack pointer.\n - On entry to the asm block the stack pointer is guaranteed to be suitably aligned (according to the target ABI) for a function call.\n - You are responsible for making sure you don't overflow the stack (e.g. use stack probing to ensure you hit a guard page).\n - You should adjust the stack pointer when allocating stack memory as required by the target ABI.\n - The stack pointer must be restored to its original value before leaving the asm block.\n- If the `noreturn` option is set then behavior is undefined if execution falls through to the end of the asm block.\n- If the `pure` option is set then behavior is undefined if the `asm` has side-effects other than its direct outputs. Behavior is also undefined if two executions of the `asm` code with the same inputs result in different outputs.\n - When used with the `nomem` option, \"inputs\" are just the direct inputs of the `asm!`.\n - When used with the `readonly` option, \"inputs\" comprise the direct inputs of the `asm!` and any memory that the `asm!` block is allowed to read.\n- These flags registers must be restored upon exiting the asm block if the `preserves_flags` option is set:\n - x86\n - Status flags in `EFLAGS` (CF, PF, AF, ZF, SF, OF).\n - Floating-point status word (all).\n - Floating-point exception flags in `MXCSR` (PE, UE, OE, ZE, DE, IE).\n - ARM\n - Condition flags in `CPSR` (N, Z, C, V)\n - Saturation flag in `CPSR` (Q)\n - Greater than or equal flags in `CPSR` (GE).\n - Condition flags in `FPSCR` (N, Z, C, V)\n - Saturation flag in `FPSCR` (QC)\n - Floating-point exception flags in `FPSCR` (IDC, IXC, UFC, OFC, DZC, IOC).\n - AArch64\n - Condition flags (`NZCV` register).\n - Floating-point status (`FPSR` register).\n - RISC-V\n - Floating-point exception flags in `fcsr` (`fflags`).\n- On x86, the direction flag (DF in `EFLAGS`) is clear on entry to an asm block and must be clear on exit.\n - Behavior is undefined if the direction flag is set on exiting an asm block.\n- The requirement of restoring the stack pointer and non-output registers to their original value only applies when exiting an `asm!` block.\n - This means that `asm!` blocks that never return (even if not marked `noreturn`) don't need to preserve these registers.\n - When returning to a different `asm!` block than you entered (e.g. for context switching), these registers must contain the value they had upon entering the `asm!` block that you are *exiting*.\n - You cannot exit an `asm!` block that has not been entered. Neither can you exit an `asm!` block that has already been exited.\n - You are responsible for switching any target-specific state (e.g. thread-local storage, stack bounds).\n - The set of memory locations that you may access is the intersection of those allowed by the `asm!` blocks you entered and exited.\n- You cannot assume that an `asm!` block will appear exactly once in the output binary. The compiler is allowed to instantiate multiple copies of the `asm!` block, for example when the function containing it is inlined in multiple places.\n - As a consequence, you should only use [local labels] inside inline assembly code. Defining symbols in assembly code may lead to assembler and/or linker errors due to duplicate symbol definitions.\n\n> **Note**: As a general rule, the flags covered by `preserves_flags` are those which are *not* preserved when performing a function call.\n\n[local labels]: https://sourceware.org/binutils/docs/as/Symbol-Names.html#Local-Labels\n" } , LintCompletion { label : "is_sorted" ,

This is useful for very low level programming, where\nwhich register you use is important:\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# unsafe fn read_byte_in(port: u16) -> u8 {\nlet result: u8;\nllvm_asm!(\"in %dx, %al\" : \"={al}\"(result) : \"{dx}\"(port));\nresult\n# }\n```\n\n## Clobbers\n\nSome instructions modify registers which might otherwise have held\ndifferent values so we use the clobbers list to indicate to the\ncompiler not to assume any values loaded into those registers will\nstay valid.\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# fn main() { unsafe {\n// Put the value 0x200 in eax:\nllvm_asm!(\"mov $$0x200, %eax\" : /* no outputs */ : /* no inputs */ : \"eax\");\n# } }\n# #[cfg(not(any(target_arch = \"x86\", target_arch = \"x86_64\")))]\n# fn main() {}\n```\n\nInput and output registers need not be listed since that information\nis already communicated by the given constraints. Otherwise, any other\nregisters used either implicitly or explicitly should be listed.\n\nIf the assembly changes the condition code register `cc` should be\nspecified as one of the clobbers. Similarly, if the assembly modifies\nmemory, `memory` should also be specified.\n\n## Options\n\nThe last section, `options` is specific to Rust. The format is comma\nseparated literal strings (i.e. `:\"foo\", \"bar\", \"baz\"`). It's used to\nspecify some extra info about the inline assembly:\n\nCurrent valid options are:\n\n1. *volatile* - specifying this is analogous to\n `__asm__ __volatile__ (...)` in gcc/clang.\n2. *alignstack* - certain instructions expect the stack to be\n aligned a certain way (i.e. SSE) and specifying this indicates to\n the compiler to insert its usual stack alignment code\n3. *intel* - use intel syntax instead of the default AT&T.\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# fn main() {\nlet result: i32;\nunsafe {\n llvm_asm!(\"mov eax, 2\" : \"={eax}\"(result) : : : \"intel\")\n}\nprintln!(\"eax is currently {}\", result);\n# }\n# #[cfg(not(any(target_arch = \"x86\", target_arch = \"x86_64\")))]\n# fn main() {}\n```\n\n## More Information\n\nThe current implementation of the `llvm_asm!` macro is a direct binding to [LLVM's\ninline assembler expressions][llvm-docs], so be sure to check out [their\ndocumentation as well][llvm-docs] for more information about clobbers,\nconstraints, etc.\n\n[llvm-docs]: http://llvm.org/docs/LangRef.html#inline-assembler-expressions\n\nIf you need more power and don't mind losing some of the niceties of\n`llvm_asm!`, check out [global_asm](global-asm.md).\n" } ] ; diff --git a/xtask/src/codegen/gen_unstable_future_descriptor.rs b/xtask/src/codegen/gen_unstable_future_descriptor.rs index 12b68378e2..122b91c069 100644 --- a/xtask/src/codegen/gen_unstable_future_descriptor.rs +++ b/xtask/src/codegen/gen_unstable_future_descriptor.rs @@ -50,6 +50,7 @@ pub fn generate_unstable_future_descriptor(mode: Mode) -> Result<()> { let ts = quote! { use crate::completion::LintCompletion; + #[rustfmt::skip] pub const UNSTABLE_FEATURE_DESCRIPTOR: &[LintCompletion] = &[ #(#definitions),* ]; From fab733b3ae55245d6fda3fd1ebc89e72b5d31fcd Mon Sep 17 00:00:00 2001 From: Dmitry Date: Sun, 9 Aug 2020 23:55:45 +0700 Subject: [PATCH 09/20] Revert "fixes" This reverts commit b602c73911864a86c94d8b306648738f5f995167. --- crates/ra_ide/src/completion.rs | 10 +++++----- xtask/src/codegen/gen_unstable_future_descriptor.rs | 2 +- 2 files changed, 6 insertions(+), 6 deletions(-) diff --git a/crates/ra_ide/src/completion.rs b/crates/ra_ide/src/completion.rs index 9c33a5a43b..a537b68b1f 100644 --- a/crates/ra_ide/src/completion.rs +++ b/crates/ra_ide/src/completion.rs @@ -21,19 +21,19 @@ mod complete_trait_impl; mod unstable_feature_descriptor; use ra_ide_db::RootDatabase; +#[rustfmt::skip] use crate::{ completion::{ completion_context::CompletionContext, completion_item::{CompletionKind, Completions}, + + //TODO: cyclic imports caused by xtask generation, this should be better + unstable_feature_descriptor::UNSTABLE_FEATURE_DESCRIPTOR, + complete_attribute::LintCompletion, }, FilePosition, }; -//FIXME: cyclic imports caused by xtask generation, this should be better -use crate::completion::{ - complete_attribute::LintCompletion, unstable_feature_descriptor::UNSTABLE_FEATURE_DESCRIPTOR, -}; - pub use crate::completion::{ completion_config::CompletionConfig, completion_item::{CompletionItem, CompletionItemKind, CompletionScore, InsertTextFormat}, diff --git a/xtask/src/codegen/gen_unstable_future_descriptor.rs b/xtask/src/codegen/gen_unstable_future_descriptor.rs index 122b91c069..84849d3d5e 100644 --- a/xtask/src/codegen/gen_unstable_future_descriptor.rs +++ b/xtask/src/codegen/gen_unstable_future_descriptor.rs @@ -21,7 +21,7 @@ pub fn generate_unstable_future_descriptor(mode: Mode) -> Result<()> { .args(&["sparse-checkout", "set", "/src/doc/unstable-book/src/"]) .output()?; Command::new("git").current_dir(path.clone()).args(&["pull", "origin", "master"]).output()?; - //FIXME: check git, and do pull + //TODO: check git, and do pull let src_dir = path.join("src/doc/unstable-book/src"); let files = WalkDir::new(src_dir.join("language-features")) From 751d0367c2de63903897570f03c9dc1a4d5eb52a Mon Sep 17 00:00:00 2001 From: Dmitry Date: Mon, 10 Aug 2020 00:35:42 +0700 Subject: [PATCH 10/20] fix tidy check --- xtask/tests/tidy.rs | 2 ++ 1 file changed, 2 insertions(+) diff --git a/xtask/tests/tidy.rs b/xtask/tests/tidy.rs index d65a2acbca..15a93b7a24 100644 --- a/xtask/tests/tidy.rs +++ b/xtask/tests/tidy.rs @@ -97,6 +97,8 @@ fn check_todo(path: &Path, text: &str) { // To support generating `todo!()` in assists, we have `expr_todo()` in // `ast::make`.

A generator is a \"resumable function\" that syntactically\nresembles a closure but compiles to much different semantics in the compiler\nitself. The primary feature of a generator is that it can be suspended during\nexecution to be resumed at a later date. Generators use the `yield` keyword to\n\"return\", and then the caller can `resume` a generator to resume execution just\nafter the `yield` keyword.\n\nGenerators are an extra-unstable feature in the compiler right now. Added in\n[RFC 2033] they're mostly intended right now as a information/constraint\ngathering phase. The intent is that experimentation can happen on the nightly\ncompiler before actual stabilization. A further RFC will be required to\nstabilize generators/coroutines and will likely contain at least a few small\ntweaks to the overall design.\n\n[RFC 2033]: https://github.com/rust-lang/rfcs/pull/2033\n\nA syntactical example of a generator is:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::{Generator, GeneratorState};\nuse std::pin::Pin;\n\nfn main() {\n let mut generator = || {\n yield 1;\n return \"foo\"\n };\n\n match Pin::new(&mut generator).resume(()) {\n GeneratorState::Yielded(1) => {}\n _ => panic!(\"unexpected value from resume\"),\n }\n match Pin::new(&mut generator).resume(()) {\n GeneratorState::Complete(\"foo\") => {}\n _ => panic!(\"unexpected value from resume\"),\n }\n}\n```\n\nGenerators are closure-like literals which can contain a `yield` statement. The\n`yield` statement takes an optional expression of a value to yield out of the\ngenerator. All generator literals implement the `Generator` trait in the\n`std::ops` module. The `Generator` trait has one main method, `resume`, which\nresumes execution of the generator at the previous suspension point.\n\nAn example of the control flow of generators is that the following example\nprints all numbers in order:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::Generator;\nuse std::pin::Pin;\n\nfn main() {\n let mut generator = || {\n println!(\"2\");\n yield;\n println!(\"4\");\n };\n\n println!(\"1\");\n Pin::new(&mut generator).resume(());\n println!(\"3\");\n Pin::new(&mut generator).resume(());\n println!(\"5\");\n}\n```\n\nAt this time the main intended use case of generators is an implementation\nprimitive for async/await syntax, but generators will likely be extended to\nergonomic implementations of iterators and other primitives in the future.\nFeedback on the design and usage is always appreciated!\n\n### The `Generator` trait\n\nThe `Generator` trait in `std::ops` currently looks like:\n\n```rust\n# #![feature(arbitrary_self_types, generator_trait)]\n# use std::ops::GeneratorState;\n# use std::pin::Pin;\n\npub trait Generator {\n type Yield;\n type Return;\n fn resume(self: Pin<&mut Self>, resume: R) -> GeneratorState;\n}\n```\n\nThe `Generator::Yield` type is the type of values that can be yielded with the\n`yield` statement. The `Generator::Return` type is the returned type of the\ngenerator. This is typically the last expression in a generator's definition or\nany value passed to `return` in a generator. The `resume` function is the entry\npoint for executing the `Generator` itself.\n\nThe return value of `resume`, `GeneratorState`, looks like:\n\n```rust\npub enum GeneratorState {\n Yielded(Y),\n Complete(R),\n}\n```\n\nThe `Yielded` variant indicates that the generator can later be resumed. This\ncorresponds to a `yield` point in a generator. The `Complete` variant indicates\nthat the generator is complete and cannot be resumed again. Calling `resume`\nafter a generator has returned `Complete` will likely result in a panic of the\nprogram.\n\n### Closure-like semantics\n\nThe closure-like syntax for generators alludes to the fact that they also have\nclosure-like semantics. Namely:\n\n* When created, a generator executes no code. A closure literal does not\n actually execute any of the closure's code on construction, and similarly a\n generator literal does not execute any code inside the generator when\n constructed.\n\n* Generators can capture outer variables by reference or by move, and this can\n be tweaked with the `move` keyword at the beginning of the closure. Like\n closures all generators will have an implicit environment which is inferred by\n the compiler. Outer variables can be moved into a generator for use as the\n generator progresses.\n\n* Generator literals produce a value with a unique type which implements the\n `std::ops::Generator` trait. This allows actual execution of the generator\n through the `Generator::resume` method as well as also naming it in return\n types and such.\n\n* Traits like `Send` and `Sync` are automatically implemented for a `Generator`\n depending on the captured variables of the environment. Unlike closures,\n generators also depend on variables live across suspension points. This means\n that although the ambient environment may be `Send` or `Sync`, the generator\n itself may not be due to internal variables live across `yield` points being\n not-`Send` or not-`Sync`. Note that generators do\n not implement traits like `Copy` or `Clone` automatically.\n\n* Whenever a generator is dropped it will drop all captured environment\n variables.\n\n### Generators as state machines\n\nIn the compiler, generators are currently compiled as state machines. Each\n`yield` expression will correspond to a different state that stores all live\nvariables over that suspension point. Resumption of a generator will dispatch on\nthe current state and then execute internally until a `yield` is reached, at\nwhich point all state is saved off in the generator and a value is returned.\n\nLet's take a look at an example to see what's going on here:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::Generator;\nuse std::pin::Pin;\n\nfn main() {\n let ret = \"foo\";\n let mut generator = move || {\n yield 1;\n return ret\n };\n\n Pin::new(&mut generator).resume(());\n Pin::new(&mut generator).resume(());\n}\n```\n\nThis generator literal will compile down to something similar to:\n\n```rust\n#![feature(arbitrary_self_types, generators, generator_trait)]\n\nuse std::ops::{Generator, GeneratorState};\nuse std::pin::Pin;\n\nfn main() {\n let ret = \"foo\";\n let mut generator = {\n enum __Generator {\n Start(&'static str),\n Yield1(&'static str),\n Done,\n }\n\n impl Generator for __Generator {\n type Yield = i32;\n type Return = &'static str;\n\n fn resume(mut self: Pin<&mut Self>, resume: ()) -> GeneratorState {\n use std::mem;\n match mem::replace(&mut *self, __Generator::Done) {\n __Generator::Start(s) => {\n *self = __Generator::Yield1(s);\n GeneratorState::Yielded(1)\n }\n\n __Generator::Yield1(s) => {\n *self = __Generator::Done;\n GeneratorState::Complete(s)\n }\n\n __Generator::Done => {\n panic!(\"generator resumed after completion\")\n }\n }\n }\n }\n\n __Generator::Start(ret)\n };\n\n Pin::new(&mut generator).resume(());\n Pin::new(&mut generator).resume(());\n}\n```\n\nNotably here we can see that the compiler is generating a fresh type,\n`__Generator` in this case.

The syntax isn't final, either. We may need an alternative syntax for Rust 2015 because, in Rust 2015, expressions like `[e; dyn(1)]` would be ambiguous. One possible alternative proposed in the RFC is `[e; n]`: if `n` captures one or more local variables, then it is considered as `[e; dyn n]`.\n\n## Advisory on stack usage\n\nIt's advised not to casually use the `#![feature(unsized_locals)]` feature. Typical use-cases are:\n\n- When you need a by-value trait objects.\n- When you really need a fast allocation of small temporary arrays.\n\nAnother pitfall is repetitive allocation and temporaries. Currently the compiler simply extends the stack frame every time it encounters an unsized assignment. So for example, the code\n\n```rust\n#![feature(unsized_locals)]\n\nfn main() {\n let x: Box<[i32]> = Box::new([1, 2, 3, 4, 5]);\n let _x = {{{{{{{{{{*x}}}}}}}}}};\n}\n```\n\nand the code\n\n```rust\n#![feature(unsized_locals)]\n\nfn main() {\n for _ in 0..10 {\n let x: Box<[i32]> = Box::new([1, 2, 3, 4, 5]);\n let _x = *x;\n }\n}\n```\n\nwill unnecessarily extend the stack frame.\n" } , LintCompletion { label : "or_patterns" , description : "# `or_patterns`\n\nThe tracking issue for this feature is: [#54883]\n\n[#54883]: https://github.com/rust-lang/rust/issues/54883\n\n------------------------\n\nThe `or_pattern` language feature allows `|` to be arbitrarily nested within\na pattern, for example, `Some(A(0) | B(1 | 2))` becomes a valid pattern.\n\n## Examples\n\n```rust,ignore\n#![feature(or_patterns)]\n\npub enum Foo {\n Bar,\n Baz,\n Quux,\n}\n\npub fn example(maybe_foo: Option) {\n match maybe_foo {\n Some(Foo::Bar | Foo::Baz) => {\n println!(\"The value contained `Bar` or `Baz`\");\n }\n Some(_) => {\n println!(\"The value did not contain `Bar` or `Baz`\");\n }\n None => {\n println!(\"The value was `None`\");\n }\n }\n}\n```\n" } , LintCompletion { label : "member_constraints" , description : "# `member_constraints`\n\nThe tracking issue for this feature is: [#61997]\n\n[#61997]: https://github.com/rust-lang/rust/issues/61997\n\n------------------------\n\nThe `member_constraints` feature gate lets you use `impl Trait` syntax with\nmultiple unrelated lifetime parameters.\n\nA simple example is:\n\n```rust\n#![feature(member_constraints)]\n\ntrait Trait<'a, 'b> { }\nimpl Trait<'_, '_> for T {}\n\nfn foo<'a, 'b>(x: &'a u32, y: &'b u32) -> impl Trait<'a, 'b> {\n (x, y)\n}\n\nfn main() { }\n```\n\nWithout the `member_constraints` feature gate, the above example is an\nerror because both `'a` and `'b` appear in the impl Trait bounds, but\nneither outlives the other.\n" } , LintCompletion { label : "optin_builtin_traits" , description : "# `optin_builtin_traits`\n\nThe tracking issue for this feature is [#13231] \n\n[#13231]: https://github.com/rust-lang/rust/issues/13231\n\n----\n\nThe `optin_builtin_traits` feature gate allows you to define auto traits.\n\nAuto traits, like [`Send`] or [`Sync`] in the standard library, are marker traits\nthat are automatically implemented for every type, unless the type, or a type it contains, \nhas explicitly opted out via a negative impl.

These automatic impls contain a where clause for each field\nof the form `T: AutoTrait`, where `T` is the type of the field and\n`AutoTrait` is the auto trait in question. As an example, consider the\nstruct `List` and the auto trait `Send`:\n\n```rust\nstruct List {\n data: T,\n next: Option>>,\n}\n```\n\nPresuming that there is no explicit impl of `Send` for `List`, the\ncompiler will supply an automatic impl of the form:\n\n```rust\nstruct List {\n data: T,\n next: Option>>,\n}\n\nunsafe impl Send for List\nwhere\n T: Send, // from the field `data`\n Option>>: Send, // from the field `next`\n{ }\n```\n\nExplicit impls may be either positive or negative. They take the form:\n\n```rust,ignore\nimpl<...> AutoTrait for StructName<..> { }\nimpl<...> !AutoTrait for StructName<..> { }\n```\n\n## Coinduction: Auto traits permit cyclic matching\n\nUnlike ordinary trait matching, auto traits are **coinductive**. This\nmeans, in short, that cycles which occur in trait matching are\nconsidered ok. As an example, consider the recursive struct `List`\nintroduced in the previous section. In attempting to determine whether\n`List: Send`, we would wind up in a cycle: to apply the impl, we must\nshow that `Option>: Send`, which will in turn require\n`Box: Send` and then finally `List: Send` again. Under ordinary\ntrait matching, this cycle would be an error, but for an auto trait it\nis considered a successful match.\n\n## Items\n\nAuto traits cannot have any trait items, such as methods or associated types. This ensures that we can generate default implementations.\n\n## Supertraits\n\nAuto traits cannot have supertraits.

The marker is the attribute `#[lang = \"...\"]` and there are\nvarious different values of `...`, i.e. various different 'lang\nitems'.\n\nFor example, `Box` pointers require two lang items, one for allocation\nand one for deallocation. A freestanding program that uses the `Box`\nsugar for dynamic allocations via `malloc` and `free`:\n\n```rust,ignore\n#![feature(lang_items, box_syntax, start, libc, core_intrinsics)]\n#![no_std]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\nextern crate libc;\n\n#[lang = \"owned_box\"]\npub struct Box(*mut T);\n\n#[lang = \"exchange_malloc\"]\nunsafe fn allocate(size: usize, _align: usize) -> *mut u8 {\n let p = libc::malloc(size as libc::size_t) as *mut u8;\n\n // Check if `malloc` failed:\n if p as usize == 0 {\n intrinsics::abort();\n }\n\n p\n}\n\n#[lang = \"box_free\"]\nunsafe fn box_free(ptr: *mut T) {\n libc::free(ptr as *mut libc::c_void)\n}\n\n#[start]\nfn main(_argc: isize, _argv: *const *const u8) -> isize {\n let _x = box 1;\n\n 0\n}\n\n#[lang = \"eh_personality\"] extern fn rust_eh_personality() {}\n#[lang = \"panic_impl\"] extern fn rust_begin_panic(info: &PanicInfo) -> ! { unsafe { intrinsics::abort() } }\n#[no_mangle] pub extern fn rust_eh_register_frames () {}\n#[no_mangle] pub extern fn rust_eh_unregister_frames () {}\n```\n\nNote the use of `abort`: the `exchange_malloc` lang item is assumed to\nreturn a valid pointer, and so needs to do the check internally.\n\nOther features provided by lang items include:\n\n- overloadable operators via traits: the traits corresponding to the\n `==`, `<`, dereferencing (`*`) and `+` (etc.) operators are all\n marked with lang items; those specific four are `eq`, `ord`,\n `deref`, and `add` respectively.\n- stack unwinding and general failure; the `eh_personality`,\n `panic` and `panic_bounds_checks` lang items.\n- the traits in `std::marker` used to indicate types of\n various kinds; lang items `send`, `sync` and `copy`.\n- the marker types and variance indicators found in\n `std::marker`; lang items `covariant_type`,\n `contravariant_lifetime`, etc.\n\nLang items are loaded lazily by the compiler; e.g. if one never uses\n`Box` then there is no need to define functions for `exchange_malloc`\nand `box_free`. `rustc` will emit an error when an item is needed\nbut not found in the current crate or any that it depends on.\n\nMost lang items are defined by `libcore`, but if you're trying to build\nan executable without the standard library, you'll run into the need\nfor lang items. The rest of this page focuses on this use-case, even though\nlang items are a bit broader than that.\n\n### Using libc\n\nIn order to build a `#[no_std]` executable we will need libc as a dependency.\nWe can specify this using our `Cargo.toml` file:\n\n```toml\n[dependencies]\nlibc = { version = \"0.2.14\", default-features = false }\n```\n\nNote that the default features have been disabled. This is a critical step -\n**the default features of libc include the standard library and so must be\ndisabled.**\n\n### Writing an executable without stdlib\n\nControlling the entry point is possible in two ways: the `#[start]` attribute,\nor overriding the default shim for the C `main` function with your own.\n\nThe function marked `#[start]` is passed the command line parameters\nin the same format as C:\n\n```rust,ignore\n#![feature(lang_items, core_intrinsics)]\n#![feature(start)]\n#![no_std]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\n// Pull in the system libc library for what crt0.o likely requires.\nextern crate libc;\n\n// Entry point for this program.\n#[start]\nfn start(_argc: isize, _argv: *const *const u8) -> isize {\n 0\n}\n\n// These functions are used by the compiler, but not\n// for a bare-bones hello world. These are normally\n// provided by libstd.\n#[lang = \"eh_personality\"]\n#[no_mangle]\npub extern fn rust_eh_personality() {\n}\n\n#[lang = \"panic_impl\"]\n#[no_mangle]\npub extern fn rust_begin_panic(info: &PanicInfo) -> ! {\n unsafe { intrinsics::abort() }\n}\n```\n\nTo override the compiler-inserted `main` shim, one has to disable it\nwith `#![no_main]` and then create the appropriate symbol with the\ncorrect ABI and the correct name, which requires overriding the\ncompiler's name mangling too:\n\n```rust,ignore\n#![feature(lang_items, core_intrinsics)]\n#![feature(start)]\n#![no_std]\n#![no_main]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\n// Pull in the system libc library for what crt0.o likely requires.\nextern crate libc;\n\n// Entry point for this program.\n#[no_mangle] // ensure that this symbol is called `main` in the output\npub extern fn main(_argc: i32, _argv: *const *const u8) -> i32 {\n 0\n}\n\n// These functions are used by the compiler, but not\n// for a bare-bones hello world.

You may observe this via linker error messages\nsuch as \"```undefined reference to `__rust_probestack'```\".\n\n## More about the language items\n\nThe compiler currently makes a few assumptions about symbols which are\navailable in the executable to call. Normally these functions are provided by\nthe standard library, but without it you must define your own. These symbols\nare called \"language items\", and they each have an internal name, and then a\nsignature that an implementation must conform to.\n\nThe first of these functions, `rust_eh_personality`, is used by the failure\nmechanisms of the compiler. This is often mapped to GCC's personality function\n(see the [libstd implementation][unwind] for more information), but crates\nwhich do not trigger a panic can be assured that this function is never\ncalled.

Negative impls are a commitment not to implement the given trait for the named types.\n\n## Orphan and overlap rules\n\nNegative impls must obey the same orphan rules as a positive impl. This implies you cannot add a negative impl for types defined in upstream crates and so forth.\n\nSimilarly, negative impls cannot overlap with positive impls, again using the same \"overlap\" check that we ordinarily use to determine if two impls overlap. (Note that positive impls typically cannot overlap with one another either, except as permitted by specialization.)\n\n## Interaction with auto traits\n\nDeclaring a negative impl `impl !SomeAutoTrait for SomeType` for an\nauto-trait serves two purposes:\n\n* as with any trait, it declares that `SomeType` will never implement `SomeAutoTrait`;\n* it disables the automatic `SomeType: SomeAutoTrait` impl that would otherwise have been generated.\n\nNote that, at present, there is no way to indicate that a given type\ndoes not implement an auto trait *but that it may do so in the\nfuture*. For ordinary types, this is done by simply not declaring any\nimpl at all, but that is not an option for auto traits. A workaround\nis that one could embed a marker type as one of the fields, where the\nmarker type is `!AutoTrait`.\n\n## Immediate uses\n\nNegative impls are used to declare that `&T: !DerefMut` and `&mut T: !Clone`, as required to fix the soundness of `Pin` described in [#66544](https://github.com/rust-lang/rust/issues/66544).\n\nThis serves two purposes:\n\n* For proving the correctness of unsafe code, we can use that impl as evidence that no `DerefMut` or `Clone` impl exists.\n* It prevents downstream crates from creating such impls.\n" } , LintCompletion { label : "abi_ptx" , description : "# `abi_ptx`\n\nThe tracking issue for this feature is: [#38788]\n\n[#38788]: https://github.com/rust-lang/rust/issues/38788\n\n------------------------\n\nWhen emitting PTX code, all vanilla Rust functions (`fn`) get translated to\n\"device\" functions.

This is\ngenerally unwanted unless you are building another plugin.\n\nThe usual practice is to put compiler plugins in their own crate, separate from\nany `macro_rules!` macros or ordinary Rust code meant to be used by consumers\nof a library.\n\n# Lint plugins\n\nPlugins can extend [Rust's lint\ninfrastructure](../../reference/attributes/diagnostics.md#lint-check-attributes) with\nadditional checks for code style, safety, etc. Now let's write a plugin\n[`lint-plugin-test.rs`](https://github.com/rust-lang/rust/blob/master/src/test/ui-fulldeps/auxiliary/lint-plugin-test.rs)\nthat warns about any item named `lintme`.\n\n```rust,ignore\n#![feature(plugin_registrar)]\n#![feature(box_syntax, rustc_private)]\n\nextern crate rustc_ast;\n\n// Load rustc as a plugin to get macros\nextern crate rustc_driver;\n#[macro_use]\nextern crate rustc_lint;\n#[macro_use]\nextern crate rustc_session;\n\nuse rustc_driver::plugin::Registry;\nuse rustc_lint::{EarlyContext, EarlyLintPass, LintArray, LintContext, LintPass};\nuse rustc_ast::ast;\ndeclare_lint!(TEST_LINT, Warn, \"Warn about items named 'lintme'\");\n\ndeclare_lint_pass!(Pass => [TEST_LINT]);\n\nimpl EarlyLintPass for Pass {\n fn check_item(&mut self, cx: &EarlyContext, it: &ast::Item) {\n if it.ident.name.as_str() == \"lintme\" {\n cx.lint(TEST_LINT, |lint| {\n lint.build(\"item is named 'lintme'\").set_span(it.span).emit()\n });\n }\n }\n}\n\n#[plugin_registrar]\npub fn plugin_registrar(reg: &mut Registry) {\n reg.lint_store.register_lints(&[&TEST_LINT]);\n reg.lint_store.register_early_pass(|| box Pass);\n}\n```\n\nThen code like\n\n```rust,ignore\n#![feature(plugin)]\n#![plugin(lint_plugin_test)]\n\nfn lintme() { }\n```\n\nwill produce a compiler warning:\n\n```txt\nfoo.rs:4:1: 4:16 warning: item is named 'lintme', #[warn(test_lint)] on by default\nfoo.rs:4 fn lintme() { }\n ^~~~~~~~~~~~~~~\n```\n\nThe components of a lint plugin are:\n\n* one or more `declare_lint!` invocations, which define static `Lint` structs;\n\n* a struct holding any state needed by the lint pass (here, none);\n\n* a `LintPass`\n implementation defining how to check each syntax element. A single\n `LintPass` may call `span_lint` for several different `Lint`s, but should\n register them all through the `get_lints` method.\n\nLint passes are syntax traversals, but they run at a late stage of compilation\nwhere type information is available. `rustc`'s [built-in\nlints](https://github.com/rust-lang/rust/blob/master/src/librustc_session/lint/builtin.rs)\nmostly use the same infrastructure as lint plugins, and provide examples of how\nto access type information.\n\nLints defined by plugins are controlled by the usual [attributes and compiler\nflags](../../reference/attributes/diagnostics.md#lint-check-attributes), e.g.\n`#[allow(test_lint)]` or `-A test-lint`. These identifiers are derived from the\nfirst argument to `declare_lint!`, with appropriate case and punctuation\nconversion.\n\nYou can run `rustc -W help foo.rs` to see a list of lints known to `rustc`,\nincluding those provided by plugins loaded by `foo.rs`.\n" } , LintCompletion { label : "concat_idents" , description : "# `concat_idents`\n\nThe tracking issue for this feature is: [#29599]\n\n[#29599]: https://github.com/rust-lang/rust/issues/29599\n\n------------------------\n\nThe `concat_idents` feature adds a macro for concatenating multiple identifiers\ninto one identifier.\n\n## Examples\n\n```rust\n#![feature(concat_idents)]\n\nfn main() {\n fn foobar() -> u32 { 23 }\n let f = concat_idents!(foo, bar);\n assert_eq!(f(), 23);\n}\n```" } , LintCompletion { label : "update_panic_count" , description : "# `update_panic_count`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "fn_traits" , description : "# `fn_traits`\n\nThe tracking issue for this feature is [#29625]\n\nSee Also: [`unboxed_closures`](../language-features/unboxed-closures.md)\n\n[#29625]: https://github.com/rust-lang/rust/issues/29625\n\n----\n\nThe `fn_traits` feature allows for implementation of the [`Fn*`] traits\nfor creating custom closure-like types.\n\n[`Fn*`]: https://doc.rust-lang.org/std/ops/trait.Fn.html\n\n```rust\n#![feature(unboxed_closures)]\n#![feature(fn_traits)]\n\nstruct Adder {\n a: u32\n}\n\nimpl FnOnce<(u32, )> for Adder {\n type Output = u32;\n extern \"rust-call\" fn call_once(self, b: (u32, )) -> Self::Output {\n self.a + b.0\n }\n}\n\nfn main() {\n let adder = Adder { a: 3 };\n assert_eq!(adder(2), 5);\n}\n```\n" } , LintCompletion { label : "try_trait" , description : "# `try_trait`\n\nThe tracking issue for this feature is: [#42327]\n\n[#42327]: https://github.com/rust-lang/rust/issues/42327\n\n------------------------\n\nThis introduces a new trait `Try` for extending the `?` operator to types\nother than `Result` (a part of [RFC 1859]).

The macro is a no-frills\ninterface to LLVM's concept of [module-level inline assembly]. That is,\nall caveats applicable to LLVM's module-level inline assembly apply\nto `global_asm!`.\n\n[module-level inline assembly]: http://llvm.org/docs/LangRef.html#module-level-inline-assembly\n\n`global_asm!` fills a role not currently satisfied by either `asm!`\nor `#[naked]` functions. The programmer has _all_ features of the\nassembler at their disposal. The linker will expect to resolve any\nsymbols defined in the inline assembly, modulo any symbols marked as\nexternal. It also means syntax for directives and assembly follow the\nconventions of the assembler in your toolchain.\n\nA simple usage looks like this:\n\n```rust,ignore\n# #![feature(global_asm)]\n# you also need relevant target_arch cfgs\nglobal_asm!(include_str!(\"something_neato.s\"));\n```\n\nAnd a more complicated usage looks like this:\n\n```rust,ignore\n# #![feature(global_asm)]\n# #![cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n\npub mod sally {\n global_asm!(r#\"\n .global foo\n foo:\n jmp baz\n \"#);\n\n #[no_mangle]\n pub unsafe extern \"C\" fn baz() {}\n}\n\n// the symbols `foo` and `bar` are global, no matter where\n// `global_asm!` was used.\nextern \"C\" {\n fn foo();\n fn bar();\n}\n\npub mod harry {\n global_asm!(r#\"\n .global bar\n bar:\n jmp quux\n \"#);\n\n #[no_mangle]\n pub unsafe extern \"C\" fn quux() {}\n}\n```\n\nYou may use `global_asm!` multiple times, anywhere in your crate, in\nwhatever way suits you. The effect is as if you concatenated all\nusages and placed the larger, single usage in the crate root.\n\n------------------------\n\nIf you don't need quite as much power and flexibility as\n`global_asm!` provides, and you don't mind restricting your inline\nassembly to `fn` bodies only, you might try the\n[asm](asm.md) feature instead.\n" } , LintCompletion { label : "sort_internals" , description : "# `sort_internals`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "test" , description : "# `test`\n\nThe tracking issue for this feature is: None.\n\n------------------------\n\nThe internals of the `test` crate are unstable, behind the `test` flag. The\nmost widely used part of the `test` crate are benchmark tests, which can test\nthe performance of your code. Let's make our `src/lib.rs` look like this\n(comments elided):\n\n```rust,ignore\n#![feature(test)]\n\nextern crate test;\n\npub fn add_two(a: i32) -> i32 {\n a + 2\n}\n\n#[cfg(test)]\nmod tests {\n use super::*;\n use test::Bencher;\n\n #[test]\n fn it_works() {\n assert_eq!(4, add_two(2));\n }\n\n #[bench]\n fn bench_add_two(b: &mut Bencher) {\n b.iter(|| add_two(2));\n }\n}\n```\n\nNote the `test` feature gate, which enables this unstable feature.\n\nWe've imported the `test` crate, which contains our benchmarking support.\nWe have a new function as well, with the `bench` attribute. Unlike regular\ntests, which take no arguments, benchmark tests take a `&mut Bencher`. This\n`Bencher` provides an `iter` method, which takes a closure. This closure\ncontains the code we'd like to benchmark.\n\nWe can run benchmark tests with `cargo bench`:\n\n```bash\n$ cargo bench\n Compiling adder v0.0.1 (file:///home/steve/tmp/adder)\n Running target/release/adder-91b3e234d4ed382a\n\nrunning 2 tests\ntest tests::it_works ... ignored\ntest tests::bench_add_two ... bench: 1 ns/iter (+/- 0)\n\ntest result: ok. 0 passed; 0 failed; 1 ignored; 1 measured\n```\n\nOur non-benchmark test was ignored. You may have noticed that `cargo bench`\ntakes a bit longer than `cargo test`. This is because Rust runs our benchmark\na number of times, and then takes the average. Because we're doing so little\nwork in this example, we have a `1 ns/iter (+/- 0)`, but this would show\nthe variance if there was one.\n\nAdvice on writing benchmarks:\n\n\n* Move setup code outside the `iter` loop; only put the part you want to measure inside\n* Make the code do \"the same thing\" on each iteration; do not accumulate or change state\n* Make the outer function idempotent too; the benchmark runner is likely to run\n it many times\n* Make the inner `iter` loop short and fast so benchmark runs are fast and the\n calibrator can adjust the run-length at fine resolution\n* Make the code in the `iter` loop do something simple, to assist in pinpointing\n performance improvements (or regressions)\n\n## Gotcha: optimizations\n\nThere's another tricky part to writing benchmarks: benchmarks compiled with\noptimizations activated can be dramatically changed by the optimizer so that\nthe benchmark is no longer benchmarking what one expects. For example, the\ncompiler might recognize that some calculation has no external effects and\nremove it entirely.\n\n```rust,ignore\n#![feature(test)]\n\nextern crate test;\nuse test::Bencher;\n\n#[bench]\nfn bench_xor_1000_ints(b: &mut Bencher) {\n b.iter(|| {\n (0..1000).fold(0, |old, new| old ^ new);\n });\n}\n```\n\ngives the following results\n\n```text\nrunning 1 test\ntest bench_xor_1000_ints ... bench: 0 ns/iter (+/- 0)\n\ntest result: ok. 0 passed; 0 failed; 0 ignored; 1 measured\n```\n\nThe benchmarking runner offers two ways to avoid this. Either, the closure that\nthe `iter` method receives can return an arbitrary value which forces the\noptimizer to consider the result used and ensures it cannot remove the\ncomputation entirely. This could be done for the example above by adjusting the\n`b.iter` call to\n\n```rust\n# struct X;\n# impl X { fn iter(&self, _: F) where F: FnMut() -> T {} } let b = X;\nb.iter(|| {\n // Note lack of `;` (could also use an explicit `return`).\n (0..1000).fold(0, |old, new| old ^ new)\n});\n```\n\nOr, the other option is to call the generic `test::black_box` function, which\nis an opaque \"black box\" to the optimizer and so forces it to consider any\nargument as used.\n\n```rust\n#![feature(test)]\n\nextern crate test;\n\n# fn main() {\n# struct X;\n# impl X { fn iter(&self, _: F) where F: FnMut() -> T {} } let b = X;\nb.iter(|| {\n let n = test::black_box(1000);\n\n (0..n).fold(0, |a, b| a ^ b)\n})\n# }\n```\n\nNeither of these read or modify the value, and are very cheap for small values.\nLarger values can be passed indirectly to reduce overhead (e.g.\n`black_box(&huge_struct)`).\n\nPerforming either of the above changes gives the following benchmarking results\n\n```text\nrunning 1 test\ntest bench_xor_1000_ints ... bench: 131 ns/iter (+/- 3)\n\ntest result: ok. 0 passed; 0 failed; 0 ignored; 1 measured\n```\n\nHowever, the optimizer can still modify a testcase in an undesirable manner\neven when using either of the above.\n" } , LintCompletion { label : "windows_stdio" , description : "# `windows_stdio`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "allocator_api" , description : "# `allocator_api`\n\nThe tracking issue for this feature is [#32838]\n\n[#32838]: https://github.com/rust-lang/rust/issues/32838\n\n------------------------\n\nSometimes you want the memory for one collection to use a different\nallocator than the memory for another collection.

Rust supports using inline\nassembly to do this via the `asm!` macro.\n\n# Guide-level explanation\n[guide-level-explanation]: #guide-level-explanation\n\nRust provides support for inline assembly via the `asm!` macro.\nIt can be used to embed handwritten assembly in the assembly output generated by the compiler.\nGenerally this should not be necessary, but might be where the required performance or timing\ncannot be otherwise achieved. Accessing low level hardware primitives, e.g. in kernel code, may also demand this functionality.\n\n> **Note**: the examples here are given in x86/x86-64 assembly, but ARM, AArch64 and RISC-V are also supported.\n\n## Basic usage\n\nLet us start with the simplest possible example:\n\n```rust,allow_fail\n# #![feature(asm)]\nunsafe {\n asm!(\"nop\");\n}\n```\n\nThis will insert a NOP (no operation) instruction into the assembly generated by the compiler.\nNote that all `asm!` invocations have to be inside an `unsafe` block, as they could insert\narbitrary instructions and break various invariants. The instructions to be inserted are listed\nin the first argument of the `asm!` macro as a string literal.\n\n## Inputs and outputs\n\nNow inserting an instruction that does nothing is rather boring. Let us do something that\nactually acts on data:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet x: u64;\nunsafe {\n asm!(\"mov {}, 5\", out(reg) x);\n}\nassert_eq!(x, 5);\n```\n\nThis will write the value `5` into the `u64` variable `x`.\nYou can see that the string literal we use to specify instructions is actually a template string.\nIt is governed by the same rules as Rust [format strings][format-syntax].\nThe arguments that are inserted into the template however look a bit different then you may\nbe familiar with. First we need to specify if the variable is an input or an output of the\ninline assembly. In this case it is an output. We declared this by writing `out`.\nWe also need to specify in what kind of register the assembly expects the variable.\nIn this case we put it in an arbitrary general purpose register by specifying `reg`.\nThe compiler will choose an appropriate register to insert into\nthe template and will read the variable from there after the inline assembly finishes executing.\n\nLet us see another example that also uses an input:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet i: u64 = 3;\nlet o: u64;\nunsafe {\n asm!(\n \"mov {0}, {1}\",\n \"add {0}, {number}\",\n out(reg) o,\n in(reg) i,\n number = const 5,\n );\n}\nassert_eq!(o, 8);\n```\n\nThis will add `5` to the input in variable `i` and write the result to variable `o`.\nThe particular way this assembly does this is first copying the value from `i` to the output,\nand then adding `5` to it.\n\nThe example shows a few things:\n\nFirst, we can see that `asm!` allows multiple template string arguments; each\none is treated as a separate line of assembly code, as if they were all joined\ntogether with newlines between them. This makes it easy to format assembly\ncode.\n\nSecond, we can see that inputs are declared by writing `in` instead of `out`.\n\nThird, one of our operands has a type we haven't seen yet, `const`.\nThis tells the compiler to expand this argument to value directly inside the assembly template.\nThis is only possible for constants and literals.\n\nFourth, we can see that we can specify an argument number, or name as in any format string.\nFor inline assembly templates this is particularly useful as arguments are often used more than once.\nFor more complex inline assembly using this facility is generally recommended, as it improves\nreadability, and allows reordering instructions without changing the argument order.\n\nWe can further refine the above example to avoid the `mov` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut x: u64 = 3;\nunsafe {\n asm!(\"add {0}, {number}\", inout(reg) x, number = const 5);\n}\nassert_eq!(x, 8);\n```\n\nWe can see that `inout` is used to specify an argument that is both input and output.\nThis is different from specifying an input and output separately in that it is guaranteed to assign both to the same register.\n\nIt is also possible to specify different variables for the input and output parts of an `inout` operand:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet x: u64 = 3;\nlet y: u64;\nunsafe {\n asm!(\"add {0}, {number}\", inout(reg) x => y, number = const 5);\n}\nassert_eq!(y, 8);\n```\n\n## Late output operands\n\nThe Rust compiler is conservative with its allocation of operands. It is assumed that an `out`\ncan be written at any time, and can therefore not share its location with any other argument.\nHowever, to guarantee optimal performance it is important to use as few registers as possible,\nso they won't have to be saved and reloaded around the inline assembly block.\nTo achieve this Rust provides a `lateout` specifier. This can be used on any output that is\nwritten only after all inputs have been consumed.\nThere is also a `inlateout` variant of this specifier.\n\nHere is an example where `inlateout` *cannot* be used:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nlet c: u64 = 4;\nunsafe {\n asm!(\n \"add {0}, {1}\",\n \"add {0}, {2}\",\n inout(reg) a,\n in(reg) b,\n in(reg) c,\n );\n}\nassert_eq!(a, 12);\n```\n\nHere the compiler is free to allocate the same register for inputs `b` and `c` since it knows they have the same value. However it must allocate a separate register for `a` since it uses `inout` and not `inlateout`. If `inlateout` was used, then `a` and `c` could be allocated to the same register, in which case the first instruction to overwrite the value of `c` and cause the assembly code to produce the wrong result.\n\nHowever the following example can use `inlateout` since the output is only modified after all input registers have been read:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nunsafe {\n asm!(\"add {0}, {1}\", inlateout(reg) a, in(reg) b);\n}\nassert_eq!(a, 8);\n```\n\nAs you can see, this assembly fragment will still work correctly if `a` and `b` are assigned to the same register.\n\n## Explicit register operands\n\nSome instructions require that the operands be in a specific register.\nTherefore, Rust inline assembly provides some more specific constraint specifiers.\nWhile `reg` is generally available on any architecture, these are highly architecture specific. E.g. for x86 the general purpose registers `eax`, `ebx`, `ecx`, `edx`, `ebp`, `esi`, and `edi`\namong others can be addressed by their name.\n\n```rust,allow_fail,no_run\n# #![feature(asm)]\nlet cmd = 0xd1;\nunsafe {\n asm!(\"out 0x64, eax\", in(\"eax\") cmd);\n}\n```\n\nIn this example we call the `out` instruction to output the content of the `cmd` variable\nto port `0x64`. Since the `out` instruction only accepts `eax` (and its sub registers) as operand\nwe had to use the `eax` constraint specifier.\n\nNote that unlike other operand types, explicit register operands cannot be used in the template string: you can't use `{}` and should write the register name directly instead. Also, they must appear at the end of the operand list after all other operand types.\n\nConsider this example which uses the x86 `mul` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nfn mul(a: u64, b: u64) -> u128 {\n let lo: u64;\n let hi: u64;\n\n unsafe {\n asm!(\n // The x86 mul instruction takes rax as an implicit input and writes\n // the 128-bit result of the multiplication to rax:rdx.\n \"mul {}\",\n in(reg) a,\n inlateout(\"rax\") b => lo,\n lateout(\"rdx\") hi\n );\n }\n\n ((hi as u128) << 64) + lo as u128\n}\n```\n\nThis uses the `mul` instruction to multiply two 64-bit inputs with a 128-bit result.\nThe only explicit operand is a register, that we fill from the variable `a`.\nThe second operand is implicit, and must be the `rax` register, which we fill from the variable `b`.\nThe lower 64 bits of the result are stored in `rax` from which we fill the variable `lo`.\nThe higher 64 bits are stored in `rdx` from which we fill the variable `hi`.\n\n## Clobbered registers\n\nIn many cases inline assembly will modify state that is not needed as an output.\nUsually this is either because we have to use a scratch register in the assembly,\nor instructions modify state that we don't need to further examine.\nThis state is generally referred to as being \"clobbered\".\nWe need to tell the compiler about this since it may need to save and restore this state\naround the inline assembly block.\n\n```rust,allow_fail\n# #![feature(asm)]\nlet ebx: u32;\nlet ecx: u32;\n\nunsafe {\n asm!(\n \"cpuid\",\n // EAX 4 selects the \"Deterministic Cache Parameters\" CPUID leaf\n inout(\"eax\") 4 => _,\n // ECX 0 selects the L0 cache information.\n inout(\"ecx\") 0 => ecx,\n lateout(\"ebx\") ebx,\n lateout(\"edx\") _,\n );\n}\n\nprintln!(\n \"L1 Cache: {}\",\n ((ebx >> 22) + 1) * (((ebx >> 12) & 0x3ff) + 1) * ((ebx & 0xfff) + 1) * (ecx + 1)\n);\n```\n\nIn the example above we use the `cpuid` instruction to get the L1 cache size.\nThis instruction writes to `eax`, `ebx`, `ecx`, and `edx`, but for the cache size we only care about the contents of `ebx` and `ecx`.\n\nHowever we still need to tell the compiler that `eax` and `edx` have been modified so that it can save any values that were in these registers before the asm. This is done by declaring these as outputs but with `_` instead of a variable name, which indicates that the output value is to be discarded.\n\nThis can also be used with a general register class (e.g. `reg`) to obtain a scratch register for use inside the asm code:\n\n```rust,allow_fail\n# #![feature(asm)]\n// Multiply x by 6 using shifts and adds\nlet mut x: u64 = 4;\nunsafe {\n asm!(\n \"mov {tmp}, {x}\",\n \"shl {tmp}, 1\",\n \"shl {x}, 2\",\n \"add {x}, {tmp}\",\n x = inout(reg) x,\n tmp = out(reg) _,\n );\n}\nassert_eq!(x, 4 * 6);\n```\n\n## Symbol operands\n\nA special operand type, `sym`, allows you to use the symbol name of a `fn` or `static` in inline assembly code.\nThis allows you to call a function or access a global variable without needing to keep its address in a register.\n\n```rust,allow_fail\n# #![feature(asm)]\nextern \"C\" fn foo(arg: i32) {\n println!(\"arg = {}\", arg);\n}\n\nfn call_foo(arg: i32) {\n unsafe {\n asm!(\n \"call {}\",\n sym foo,\n // 1st argument in rdi, which is caller-saved\n inout(\"rdi\") arg => _,\n // All caller-saved registers must be marked as clobberred\n out(\"rax\") _, out(\"rcx\") _, out(\"rdx\") _, out(\"rsi\") _,\n out(\"r8\") _, out(\"r9\") _, out(\"r10\") _, out(\"r11\") _,\n out(\"xmm0\") _, out(\"xmm1\") _, out(\"xmm2\") _, out(\"xmm3\") _,\n out(\"xmm4\") _, out(\"xmm5\") _, out(\"xmm6\") _, out(\"xmm7\") _,\n out(\"xmm8\") _, out(\"xmm9\") _, out(\"xmm10\") _, out(\"xmm11\") _,\n out(\"xmm12\") _, out(\"xmm13\") _, out(\"xmm14\") _, out(\"xmm15\") _,\n )\n }\n}\n```\n\nNote that the `fn` or `static` item does not need to be public or `#[no_mangle]`:\nthe compiler will automatically insert the appropriate mangled symbol name into the assembly code.\n\n## Register template modifiers\n\nIn some cases, fine control is needed over the way a register name is formatted when inserted into the template string. This is needed when an architecture's assembly language has several names for the same register, each typically being a \"view\" over a subset of the register (e.g. the low 32 bits of a 64-bit register).\n\nBy default the compiler will always choose the name that refers to the full register size (e.g. `rax` on x86-64, `eax` on x86, etc).\n\nThis default can be overriden by using modifiers on the template string operands, just like you would with format strings:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut x: u16 = 0xab;\n\nunsafe {\n asm!(\"mov {0:h}, {0:l}\", inout(reg_abcd) x);\n}\n\nassert_eq!(x, 0xabab);\n```\n\nIn this example, we use the `reg_abcd` register class to restrict the register allocator to the 4 legacy x86 register (`ax`, `bx`, `cx`, `dx`) of which the first two bytes can be addressed independently.\n\nLet us assume that the register allocator has chosen to allocate `x` in the `ax` register.\nThe `h` modifier will emit the register name for the high byte of that register and the `l` modifier will emit the register name for the low byte. The asm code will therefore be expanded as `mov ah, al` which copies the low byte of the value into the high byte.\n\nIf you use a smaller data type (e.g. `u16`) with an operand and forget the use template modifiers, the compiler will emit a warning and suggest the correct modifier to use.\n\n## Options\n\nBy default, an inline assembly block is treated the same way as an external FFI function call with a custom calling convention: it may read/write memory, have observable side effects, etc. However in many cases, it is desirable to give the compiler more information about what the assembly code is actually doing so that it can optimize better.\n\nLet's take our previous example of an `add` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nunsafe {\n asm!(\n \"add {0}, {1}\",\n inlateout(reg) a, in(reg) b,\n options(pure, nomem, nostack),\n );\n}\nassert_eq!(a, 8);\n```\n\nOptions can be provided as an optional final argument to the `asm!` macro. We specified three options here:\n- `pure` means that the asm code has no observable side effects and that its output depends only on its inputs. This allows the compiler optimizer to call the inline asm fewer times or even eliminate it entirely.\n- `nomem` means that the asm code does not read or write to memory. By default the compiler will assume that inline assembly can read or write any memory address that is accessible to it (e.g. through a pointer passed as an operand, or a global).\n- `nostack` means that the asm code does not push any data onto the stack. This allows the compiler to use optimizations such as the stack red zone on x86-64 to avoid stack pointer adjustments.\n\nThese allow the compiler to better optimize code using `asm!`, for example by eliminating pure `asm!` blocks whose outputs are not needed.\n\nSee the reference for the full list of available options and their effects.\n\n# Reference-level explanation\n[reference-level-explanation]: #reference-level-explanation\n\nInline assembler is implemented as an unsafe macro `asm!()`.\nThe first argument to this macro is a template string literal used to build the final assembly.\nThe following arguments specify input and output operands.\nWhen required, options are specified as the final argument.\n\nThe following ABNF specifies the general syntax:\n\n```ignore\ndir_spec := \"in\" / \"out\" / \"lateout\" / \"inout\" / \"inlateout\"\nreg_spec := / \"\"\noperand_expr := expr / \"_\" / expr \"=>\" expr / expr \"=>\" \"_\"\nreg_operand := dir_spec \"(\" reg_spec \")\" operand_expr\noperand := reg_operand / \"const\" const_expr / \"sym\" path\noption := \"pure\" / \"nomem\" / \"readonly\" / \"preserves_flags\" / \"noreturn\" / \"att_syntax\"\noptions := \"options(\" option *[\",\" option] [\",\"] \")\"\nasm := \"asm!(\" format_string *(\",\" format_string) *(\",\" [ident \"=\"] operand) [\",\" options] [\",\"] \")\"\n```\n\nThe macro will initially be supported only on ARM, AArch64, Hexagon, x86, x86-64 and RISC-V targets. Support for more targets may be added in the future. The compiler will emit an error if `asm!` is used on an unsupported target.\n\n[format-syntax]: https://doc.rust-lang.org/std/fmt/#syntax\n\n## Template string arguments\n\nThe assembler template uses the same syntax as [format strings][format-syntax] (i.e. placeholders are specified by curly braces). The corresponding arguments are accessed in order, by index, or by name. However, implicit named arguments (introduced by [RFC #2795][rfc-2795]) are not supported.\n\nAn `asm!` invocation may have one or more template string arguments; an `asm!` with multiple template string arguments is treated as if all the strings were concatenated with a `\\n` between them. The expected usage is for each template string argument to correspond to a line of assembly code. All template string arguments must appear before any other arguments.\n\nAs with format strings, named arguments must appear after positional arguments. Explicit register operands must appear at the end of the operand list, after named arguments if any.\n\nExplicit register operands cannot be used by placeholders in the template string. All other named and positional operands must appear at least once in the template string, otherwise a compiler error is generated.\n\nThe exact assembly code syntax is target-specific and opaque to the compiler except for the way operands are substituted into the template string to form the code passed to the assembler.\n\nThe 5 targets specified in this RFC (x86, ARM, AArch64, RISC-V, Hexagon) all use the assembly code syntax of the GNU assembler (GAS). On x86, the `.intel_syntax noprefix` mode of GAS is used by default. On ARM, the `.syntax unified` mode is used. These targets impose an additional restriction on the assembly code: any assembler state (e.g. the current section which can be changed with `.section`) must be restored to its original value at the end of the asm string. Assembly code that does not conform to the GAS syntax will result in assembler-specific behavior.\n\n[rfc-2795]: https://github.com/rust-lang/rfcs/pull/2795\n\n## Operand type\n\nSeveral types of operands are supported:\n\n* `in() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain the value of `` at the start of the asm code.\n - The allocated register must contain the same value at the end of the asm code (except if a `lateout` is allocated to the same register).\n* `out() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain an undefined value at the start of the asm code.\n - `` must be a (possibly uninitialized) place expression, to which the contents of the allocated register is written to at the end of the asm code.\n - An underscore (`_`) may be specified instead of an expression, which will cause the contents of the register to be discarded at the end of the asm code (effectively acting as a clobber).\n* `lateout() `\n - Identical to `out` except that the register allocator can reuse a register allocated to an `in`.\n - You should only write to the register after all inputs are read, otherwise you may clobber an input.\n* `inout() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain the value of `` at the start of the asm code.\n - `` must be a mutable initialized place expression, to which the contents of the allocated register is written to at the end of the asm code.\n* `inout() => `\n - Same as `inout` except that the initial value of the register is taken from the value of ``.\n - `` must be a (possibly uninitialized) place expression, to which the contents of the allocated register is written to at the end of the asm code.\n - An underscore (`_`) may be specified instead of an expression for ``, which will cause the contents of the register to be discarded at the end of the asm code (effectively acting as a clobber).\n - `` and `` may have different types.\n* `inlateout() ` / `inlateout() => `\n - Identical to `inout` except that the register allocator can reuse a register allocated to an `in` (this can happen if the compiler knows the `in` has the same initial value as the `inlateout`).\n - You should only write to the register after all inputs are read, otherwise you may clobber an input.\n* `const `\n - `` must be an integer or floating-point constant expression.\n - The value of the expression is formatted as a string and substituted directly into the asm template string.\n* `sym `\n - `` must refer to a `fn` or `static`.\n - A mangled symbol name referring to the item is substituted into the asm template string.\n - The substituted string does not include any modifiers (e.g. GOT, PLT, relocations, etc).\n - `` is allowed to point to a `#[thread_local]` static, in which case the asm code can combine the symbol with relocations (e.g. `@plt`, `@TPOFF`) to read from thread-local data.\n\nOperand expressions are evaluated from left to right, just like function call arguments. After the `asm!` has executed, outputs are written to in left to right order. This is significant if two outputs point to the same place: that place will contain the value of the rightmost output.\n\n## Register operands\n\nInput and output operands can be specified either as an explicit register or as a register class from which the register allocator can select a register. Explicit registers are specified as string literals (e.g. `\"eax\"`) while register classes are specified as identifiers (e.g. `reg`). Using string literals for register names enables support for architectures that use special characters in register names, such as MIPS (`$0`, `$1`, etc).\n\nNote that explicit registers treat register aliases (e.g. `r14` vs `lr` on ARM) and smaller views of a register (e.g. `eax` vs `rax`) as equivalent to the base register. It is a compile-time error to use the same explicit register for two input operands or two output operands. Additionally, it is also a compile-time error to use overlapping registers (e.g. ARM VFP) in input operands or in output operands.\n\nOnly the following types are allowed as operands for inline assembly:\n- Integers (signed and unsigned)\n- Floating-point numbers\n- Pointers (thin only)\n- Function pointers\n- SIMD vectors (structs defined with `#[repr(simd)]` and which implement `Copy`). This includes architecture-specific vector types defined in `std::arch` such as `__m128` (x86) or `int8x16_t` (ARM).\n\nHere is the list of currently supported register classes:\n\n| Architecture | Register class | Registers | LLVM constraint code |\n| ------------ | -------------- | --------- | -------------------- |\n| x86 | `reg` | `ax`, `bx`, `cx`, `dx`, `si`, `di`, `r[8-15]` (x86-64 only) | `r` |\n| x86 | `reg_abcd` | `ax`, `bx`, `cx`, `dx` | `Q` |\n| x86-32 | `reg_byte` | `al`, `bl`, `cl`, `dl`, `ah`, `bh`, `ch`, `dh` | `q` |\n| x86-64 | `reg_byte` | `al`, `bl`, `cl`, `dl`, `sil`, `dil`, `r[8-15]b`, `ah`\\*, `bh`\\*, `ch`\\*, `dh`\\* | `q` |\n| x86 | `xmm_reg` | `xmm[0-7]` (x86) `xmm[0-15]` (x86-64) | `x` |\n| x86 | `ymm_reg` | `ymm[0-7]` (x86) `ymm[0-15]` (x86-64) | `x` |\n| x86 | `zmm_reg` | `zmm[0-7]` (x86) `zmm[0-31]` (x86-64) | `v` |\n| x86 | `kreg` | `k[1-7]` | `Yk` |\n| AArch64 | `reg` | `x[0-28]`, `x30` | `r` |\n| AArch64 | `vreg` | `v[0-31]` | `w` |\n| AArch64 | `vreg_low16` | `v[0-15]` | `x` |\n| ARM | `reg` | `r[0-5]` `r7`\\*, `r[8-10]`, `r11`\\*, `r12`, `r14` | `r` |\n| ARM (Thumb) | `reg_thumb` | `r[0-r7]` | `l` |\n| ARM (ARM) | `reg_thumb` | `r[0-r10]`, `r12`, `r14` | `l` |\n| ARM | `sreg` | `s[0-31]` | `t` |\n| ARM | `sreg_low16` | `s[0-15]` | `x` |\n| ARM | `dreg` | `d[0-31]` | `w` |\n| ARM | `dreg_low16` | `d[0-15]` | `t` |\n| ARM | `dreg_low8` | `d[0-8]` | `x` |\n| ARM | `qreg` | `q[0-15]` | `w` |\n| ARM | `qreg_low8` | `q[0-7]` | `t` |\n| ARM | `qreg_low4` | `q[0-3]` | `x` |\n| NVPTX | `reg16` | None\\* | `h` |\n| NVPTX | `reg32` | None\\* | `r` |\n| NVPTX | `reg64` | None\\* | `l` |\n| RISC-V | `reg` | `x1`, `x[5-7]`, `x[9-15]`, `x[16-31]` (non-RV32E) | `r` |\n| RISC-V | `freg` | `f[0-31]` | `f` |\n| Hexagon | `reg` | `r[0-28]` | `r` |\n\n> **Note**: On x86 we treat `reg_byte` differently from `reg` because the compiler can allocate `al` and `ah` separately whereas `reg` reserves the whole register.\n>\n> Note #2: On x86-64 the high byte registers (e.g. `ah`) are only available when used as an explicit register. Specifying the `reg_byte` register class for an operand will always allocate a low byte register.\n>\n> Note #3: NVPTX doesn't have a fixed register set, so named registers are not supported.\n>\n> Note #4: On ARM the frame pointer is either `r7` or `r11` depending on the platform.\n\nAdditional register classes may be added in the future based on demand (e.g. MMX, x87, etc).\n\nEach register class has constraints on which value types they can be used with. This is necessary because the way a value is loaded into a register depends on its type. For example, on big-endian systems, loading a `i32x4` and a `i8x16` into a SIMD register may result in different register contents even if the byte-wise memory representation of both values is identical. The availability of supported types for a particular register class may depend on what target features are currently enabled.\n\n| Architecture | Register class | Target feature | Allowed types |\n| ------------ | -------------- | -------------- | ------------- |\n| x86-32 | `reg` | None | `i16`, `i32`, `f32` |\n| x86-64 | `reg` | None | `i16`, `i32`, `f32`, `i64`, `f64` |\n| x86 | `reg_byte` | None | `i8` |\n| x86 | `xmm_reg` | `sse` | `i32`, `f32`, `i64`, `f64`,

The only exception is the `freg` register class on RISC-V where `f32` values are NaN-boxed in a `f64` as required by the RISC-V architecture.\n\nWhen separate input and output expressions are specified for an `inout` operand, both expressions must have the same type. The only exception is if both operands are pointers or integers, in which case they are only required to have the same size. This restriction exists because the register allocators in LLVM and GCC sometimes cannot handle tied operands with different types.\n\n## Register names\n\nSome registers have multiple names.

The frame pointer cannot be used as an input or output. |\n| ARM | `r6` | `r6` is used internally by LLVM as a base pointer and therefore cannot be used as an input or output. |\n| x86 | `k0` | This is a constant zero register which can't be modified. |\n| x86 | `ip` | This is the program counter, not a real register. |\n| x86 | `mm[0-7]` | MMX registers are not currently supported (but may be in the future). |\n| x86 | `st([0-7])` | x87 registers are not currently supported (but may be in the future). |\n| AArch64 | `xzr` | This is a constant zero register which can't be modified. |\n| ARM | `pc` | This is the program counter, not a real register. |\n| RISC-V | `x0` | This is a constant zero register which can't be modified. |\n| RISC-V | `gp`, `tp` | These registers are reserved and cannot be used as inputs or outputs. |\n| Hexagon | `lr` | This is the link register which cannot be used as an input or output. |\n\n## Template modifiers\n\nThe placeholders can be augmented by modifiers which are specified after the `:` in the curly braces. These modifiers do not affect register allocation, but change the way operands are formatted when inserted into the template string. Only one modifier is allowed per template placeholder.\n\nThe supported modifiers are a subset of LLVM's (and GCC's) [asm template argument modifiers][llvm-argmod], but do not use the same letter codes.\n\n| Architecture | Register class | Modifier | Example output | LLVM modifier |\n| ------------ | -------------- | -------- | -------------- | ------------- |\n| x86-32 | `reg` | None | `eax` | `k` |\n| x86-64 | `reg` | None | `rax` | `q` |\n| x86-32 | `reg_abcd` | `l` | `al` | `b` |\n| x86-64 | `reg` | `l` | `al` | `b` |\n| x86 | `reg_abcd` | `h` | `ah` | `h` |\n| x86 | `reg` | `x` | `ax` | `w` |\n| x86 | `reg` | `e` | `eax` | `k` |\n| x86-64 | `reg` | `r` | `rax` | `q` |\n| x86 | `reg_byte` | None | `al` / `ah` | None |\n| x86 | `xmm_reg` | None | `xmm0` | `x` |\n| x86 | `ymm_reg` | None | `ymm0` | `t` |\n| x86 | `zmm_reg` | None | `zmm0` | `g` |\n| x86 | `*mm_reg` | `x` | `xmm0` | `x` |\n| x86 | `*mm_reg` | `y` | `ymm0` | `t` |\n| x86 | `*mm_reg` | `z` | `zmm0` | `g` |\n| x86 | `kreg` | None | `k1` | None |\n| AArch64 | `reg` | None | `x0` | `x` |\n| AArch64 | `reg` | `w` | `w0` | `w` |\n| AArch64 | `reg` | `x` | `x0` | `x` |\n| AArch64 | `vreg` | None | `v0` | None |\n| AArch64 | `vreg` | `v` | `v0` | None |\n| AArch64 | `vreg` | `b` | `b0` | `b` |\n| AArch64 | `vreg` | `h` | `h0` | `h` |\n| AArch64 | `vreg` | `s` | `s0` | `s` |\n| AArch64 | `vreg` | `d` | `d0` | `d` |\n| AArch64 | `vreg` | `q` | `q0` | `q` |\n| ARM | `reg` | None | `r0` | None |\n| ARM | `sreg` | None | `s0` | None |\n| ARM | `dreg` | None | `d0` | `P` |\n| ARM | `qreg` | None | `q0` | `q` |\n| ARM | `qreg` | `e` / `f` | `d0` / `d1` | `e` / `f` |\n| NVPTX | `reg16` | None | `rs0` | None |\n| NVPTX | `reg32` | None | `r0` | None |\n| NVPTX | `reg64` | None | `rd0` | None |\n| RISC-V | `reg` | None | `x1` | None |\n| RISC-V | `freg` | None | `f0` | None |\n| Hexagon | `reg` | None | `r0` | None |\n\n> Notes:\n> - on ARM `e` / `f`: this prints the low or high doubleword register name of a NEON quad (128-bit) register.\n> - on x86: our behavior for `reg` with no modifiers differs from what GCC does. GCC will infer the modifier based on the operand value type, while we default to the full register size.\n> - on x86 `xmm_reg`: the `x`, `t` and `g` LLVM modifiers are not yet implemented in LLVM (they are supported by GCC only), but this should be a simple change.\n\nAs stated in the previous section, passing an input value smaller than the register width will result in the upper bits of the register containing undefined values. This is not a problem if the inline asm only accesses the lower bits of the register, which can be done by using a template modifier to use a subregister name in the asm code (e.g. `ax` instead of `rax`). Since this an easy pitfall, the compiler will suggest a template modifier to use where appropriate given the input type. If all references to an operand already have modifiers then the warning is suppressed for that operand.\n\n[llvm-argmod]: http://llvm.org/docs/LangRef.html#asm-template-argument-modifiers\n\n## Options\n\nFlags are used to further influence the behavior of the inline assembly block.\nCurrently the following options are defined:\n- `pure`: The `asm` block has no side effects, and its outputs depend only on its direct inputs (i.e. the values themselves, not what they point to) or values read from memory (unless the `nomem` options is also set). This allows the compiler to execute the `asm` block fewer times than specified in the program (e.g. by hoisting it out of a loop) or even eliminate it entirely if the outputs are not used.\n- `nomem`: The `asm` blocks does not read or write to any memory. This allows the compiler to cache the values of modified global variables in registers across the `asm` block since it knows that they are not read or written to by the `asm`.\n- `readonly`: The `asm` block does not write to any memory. This allows the compiler to cache the values of unmodified global variables in registers across the `asm` block since it knows that they are not written to by the `asm`.\n- `preserves_flags`: The `asm` block does not modify the flags register (defined in the rules below). This allows the compiler to avoid recomputing the condition flags after the `asm` block.\n- `noreturn`: The `asm` block never returns, and its return type is defined as `!` (never). Behavior is undefined if execution falls through past the end of the asm code. A `noreturn` asm block behaves just like a function which doesn't return; notably, local variables in scope are not dropped before it is invoked.\n- `nostack`: The `asm` block does not push data to the stack, or write to the stack red-zone (if supported by the target). If this option is *not* used then the stack pointer is guaranteed to be suitably aligned (according to the target ABI) for a function call.\n- `att_syntax`: This option is only valid on x86, and causes the assembler to use the `.att_syntax prefix` mode of the GNU assembler. Register operands are substituted in with a leading `%`.\n\nThe compiler performs some additional checks on options:\n- The `nomem` and `readonly` options are mutually exclusive: it is a compile-time error to specify both.\n- The `pure` option must be combined with either the `nomem` or `readonly` options, otherwise a compile-time error is emitted.\n- It is a compile-time error to specify `pure` on an asm block with no outputs or only discarded outputs (`_`).\n- It is a compile-time error to specify `noreturn` on an asm block with outputs.\n\n## Rules for inline assembly\n\n- Any registers not specified as inputs will contain an undefined value on entry to the asm block.\n - An \"undefined value\" in the context of inline assembly means that the register can (non-deterministically) have any one of the possible values allowed by the architecture. Notably it is not the same as an LLVM `undef` which can have a different value every time you read it (since such a concept does not exist in assembly code).\n- Any registers not specified as outputs must have the same value upon exiting the asm block as they had on entry, otherwise behavior is undefined.\n - This only applies to registers which can be specified as an input or output. Other registers follow target-specific rules.\n - Note that a `lateout` may be allocated to the same register as an `in`, in which case this rule does not apply. Code should not rely on this however since it depends on the results of register allocation.\n- Behavior is undefined if execution unwinds out of an asm block.\n - This also applies if the assembly code calls a function which then unwinds.\n- The set of memory locations that assembly code is allowed the read and write are the same as those allowed for an FFI function.\n - Refer to the unsafe code guidelines for the exact rules.\n - If the `readonly` option is set, then only memory reads are allowed.\n - If the `nomem` option is set then no reads or writes to memory are allowed.\n - These rules do not apply to memory which is private to the asm code, such as stack space allocated within the asm block.\n- The compiler cannot assume that the instructions in the asm are the ones that will actually end up executed.\n - This effectively means that the compiler must treat the `asm!` as a black box and only take the interface specification into account, not the instructions themselves.\n - Runtime code patching is allowed, via target-specific mechanisms (outside the scope of this RFC).\n- Unless the `nostack` option is set, asm code is allowed to use stack space below the stack pointer.\n - On entry to the asm block the stack pointer is guaranteed to be suitably aligned (according to the target ABI) for a function call.\n - You are responsible for making sure you don't overflow the stack (e.g. use stack probing to ensure you hit a guard page).\n - You should adjust the stack pointer when allocating stack memory as required by the target ABI.\n - The stack pointer must be restored to its original value before leaving the asm block.\n- If the `noreturn` option is set then behavior is undefined if execution falls through to the end of the asm block.\n- If the `pure` option is set then behavior is undefined if the `asm` has side-effects other than its direct outputs. Behavior is also undefined if two executions of the `asm` code with the same inputs result in different outputs.\n - When used with the `nomem` option, \"inputs\" are just the direct inputs of the `asm!`.\n - When used with the `readonly` option, \"inputs\" comprise the direct inputs of the `asm!` and any memory that the `asm!` block is allowed to read.\n- These flags registers must be restored upon exiting the asm block if the `preserves_flags` option is set:\n - x86\n - Status flags in `EFLAGS` (CF, PF, AF, ZF, SF, OF).\n - Floating-point status word (all).\n - Floating-point exception flags in `MXCSR` (PE, UE, OE, ZE, DE, IE).\n - ARM\n - Condition flags in `CPSR` (N, Z, C, V)\n - Saturation flag in `CPSR` (Q)\n - Greater than or equal flags in `CPSR` (GE).\n - Condition flags in `FPSCR` (N, Z, C, V)\n - Saturation flag in `FPSCR` (QC)\n - Floating-point exception flags in `FPSCR` (IDC, IXC, UFC, OFC, DZC, IOC).\n - AArch64\n - Condition flags (`NZCV` register).\n - Floating-point status (`FPSR` register).\n - RISC-V\n - Floating-point exception flags in `fcsr` (`fflags`).\n- On x86, the direction flag (DF in `EFLAGS`) is clear on entry to an asm block and must be clear on exit.\n - Behavior is undefined if the direction flag is set on exiting an asm block.\n- The requirement of restoring the stack pointer and non-output registers to their original value only applies when exiting an `asm!` block.\n - This means that `asm!` blocks that never return (even if not marked `noreturn`) don't need to preserve these registers.\n - When returning to a different `asm!` block than you entered (e.g. for context switching), these registers must contain the value they had upon entering the `asm!` block that you are *exiting*.\n - You cannot exit an `asm!` block that has not been entered. Neither can you exit an `asm!` block that has already been exited.\n - You are responsible for switching any target-specific state (e.g. thread-local storage, stack bounds).\n - The set of memory locations that you may access is the intersection of those allowed by the `asm!` blocks you entered and exited.\n- You cannot assume that an `asm!` block will appear exactly once in the output binary. The compiler is allowed to instantiate multiple copies of the `asm!` block, for example when the function containing it is inlined in multiple places.\n - As a consequence, you should only use [local labels] inside inline assembly code. Defining symbols in assembly code may lead to assembler and/or linker errors due to duplicate symbol definitions.\n\n> **Note**: As a general rule, the flags covered by `preserves_flags` are those which are *not* preserved when performing a function call.\n\n[local labels]: https://sourceware.org/binutils/docs/as/Symbol-Names.html#Local-Labels\n" } , LintCompletion { label : "is_sorted" ,

This is useful for very low level programming, where\nwhich register you use is important:\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# unsafe fn read_byte_in(port: u16) -> u8 {\nlet result: u8;\nllvm_asm!(\"in %dx, %al\" : \"={al}\"(result) : \"{dx}\"(port));\nresult\n# }\n```\n\n## Clobbers\n\nSome instructions modify registers which might otherwise have held\ndifferent values so we use the clobbers list to indicate to the\ncompiler not to assume any values loaded into those registers will\nstay valid.\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# fn main() { unsafe {\n// Put the value 0x200 in eax:\nllvm_asm!(\"mov $$0x200, %eax\" : /* no outputs */ : /* no inputs */ : \"eax\");\n# } }\n# #[cfg(not(any(target_arch = \"x86\", target_arch = \"x86_64\")))]\n# fn main() {}\n```\n\nInput and output registers need not be listed since that information\nis already communicated by the given constraints. Otherwise, any other\nregisters used either implicitly or explicitly should be listed.\n\nIf the assembly changes the condition code register `cc` should be\nspecified as one of the clobbers. Similarly, if the assembly modifies\nmemory, `memory` should also be specified.\n\n## Options\n\nThe last section, `options` is specific to Rust. The format is comma\nseparated literal strings (i.e. `:\"foo\", \"bar\", \"baz\"`). It's used to\nspecify some extra info about the inline assembly:\n\nCurrent valid options are:\n\n1. *volatile* - specifying this is analogous to\n `__asm__ __volatile__ (...)` in gcc/clang.\n2. *alignstack* - certain instructions expect the stack to be\n aligned a certain way (i.e. SSE) and specifying this indicates to\n the compiler to insert its usual stack alignment code\n3. *intel* - use intel syntax instead of the default AT&T.\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# fn main() {\nlet result: i32;\nunsafe {\n llvm_asm!(\"mov eax, 2\" : \"={eax}\"(result) : : : \"intel\")\n}\nprintln!(\"eax is currently {}\", result);\n# }\n# #[cfg(not(any(target_arch = \"x86\", target_arch = \"x86_64\")))]\n# fn main() {}\n```\n\n## More Information\n\nThe current implementation of the `llvm_asm!` macro is a direct binding to [LLVM's\ninline assembler expressions][llvm-docs], so be sure to check out [their\ndocumentation as well][llvm-docs] for more information about clobbers,\nconstraints, etc.\n\n[llvm-docs]: http://llvm.org/docs/LangRef.html#inline-assembler-expressions\n\nIf you need more power and don't mind losing some of the niceties of\n`llvm_asm!`, check out [global_asm](global-asm.md).\n" } ] ; +pub const UNSTABLE_FEATURE_DESCRIPTOR : & [ LintCompletion ] = & [ LintCompletion { label : "crate_visibility_modifier" , description : "# `crate_visibility_modifier`\n\nThe tracking issue for this feature is: [#53120]\n\n[#53120]: https://github.com/rust-lang/rust/issues/53120\n\n-----\n\nThe `crate_visibility_modifier` feature allows the `crate` keyword to be used\nas a visibility modifier synonymous to `pub(crate)`, indicating that a type\n(function, _&c._) is to be visible to the entire enclosing crate, but not to\nother crates.\n\n```rust\n#![feature(crate_visibility_modifier)]\n\ncrate struct Foo {\n bar: usize,\n}\n```\n" } , LintCompletion { label : "abi_thiscall" , description : "# `abi_thiscall`\n\nThe tracking issue for this feature is: [#42202]\n\n[#42202]: https://github.com/rust-lang/rust/issues/42202\n\n------------------------\n\nThe MSVC ABI on x86 Windows uses the `thiscall` calling convention for C++\ninstance methods by default; it is identical to the usual (C) calling\nconvention on x86 Windows except that the first parameter of the method,\nthe `this` pointer, is passed in the ECX register.\n" } , LintCompletion { label : "infer_static_outlives_requirements" , description : "# `infer_static_outlives_requirements`\n\nThe tracking issue for this feature is: [#54185]\n\n[#54185]: https://github.com/rust-lang/rust/issues/54185\n\n------------------------\nThe `infer_static_outlives_requirements` feature indicates that certain\n`'static` outlives requirements can be inferred by the compiler rather than\nstating them explicitly.\n\nNote: It is an accompanying feature to `infer_outlives_requirements`,\nwhich must be enabled to infer outlives requirements.\n\nFor example, currently generic struct definitions that contain\nreferences, require where-clauses of the form T: 'static.

A generator is a \"resumable function\" that syntactically\nresembles a closure but compiles to much different semantics in the compiler\nitself. The primary feature of a generator is that it can be suspended during\nexecution to be resumed at a later date. Generators use the `yield` keyword to\n\"return\", and then the caller can `resume` a generator to resume execution just\nafter the `yield` keyword.\n\nGenerators are an extra-unstable feature in the compiler right now. Added in\n[RFC 2033] they're mostly intended right now as a information/constraint\ngathering phase. The intent is that experimentation can happen on the nightly\ncompiler before actual stabilization. A further RFC will be required to\nstabilize generators/coroutines and will likely contain at least a few small\ntweaks to the overall design.\n\n[RFC 2033]: https://github.com/rust-lang/rfcs/pull/2033\n\nA syntactical example of a generator is:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::{Generator, GeneratorState};\nuse std::pin::Pin;\n\nfn main() {\n let mut generator = || {\n yield 1;\n return \"foo\"\n };\n\n match Pin::new(&mut generator).resume(()) {\n GeneratorState::Yielded(1) => {}\n _ => panic!(\"unexpected value from resume\"),\n }\n match Pin::new(&mut generator).resume(()) {\n GeneratorState::Complete(\"foo\") => {}\n _ => panic!(\"unexpected value from resume\"),\n }\n}\n```\n\nGenerators are closure-like literals which can contain a `yield` statement. The\n`yield` statement takes an optional expression of a value to yield out of the\ngenerator. All generator literals implement the `Generator` trait in the\n`std::ops` module. The `Generator` trait has one main method, `resume`, which\nresumes execution of the generator at the previous suspension point.\n\nAn example of the control flow of generators is that the following example\nprints all numbers in order:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::Generator;\nuse std::pin::Pin;\n\nfn main() {\n let mut generator = || {\n println!(\"2\");\n yield;\n println!(\"4\");\n };\n\n println!(\"1\");\n Pin::new(&mut generator).resume(());\n println!(\"3\");\n Pin::new(&mut generator).resume(());\n println!(\"5\");\n}\n```\n\nAt this time the main intended use case of generators is an implementation\nprimitive for async/await syntax, but generators will likely be extended to\nergonomic implementations of iterators and other primitives in the future.\nFeedback on the design and usage is always appreciated!\n\n### The `Generator` trait\n\nThe `Generator` trait in `std::ops` currently looks like:\n\n```rust\n# #![feature(arbitrary_self_types, generator_trait)]\n# use std::ops::GeneratorState;\n# use std::pin::Pin;\n\npub trait Generator {\n type Yield;\n type Return;\n fn resume(self: Pin<&mut Self>, resume: R) -> GeneratorState;\n}\n```\n\nThe `Generator::Yield` type is the type of values that can be yielded with the\n`yield` statement. The `Generator::Return` type is the returned type of the\ngenerator. This is typically the last expression in a generator's definition or\nany value passed to `return` in a generator. The `resume` function is the entry\npoint for executing the `Generator` itself.\n\nThe return value of `resume`, `GeneratorState`, looks like:\n\n```rust\npub enum GeneratorState {\n Yielded(Y),\n Complete(R),\n}\n```\n\nThe `Yielded` variant indicates that the generator can later be resumed. This\ncorresponds to a `yield` point in a generator. The `Complete` variant indicates\nthat the generator is complete and cannot be resumed again. Calling `resume`\nafter a generator has returned `Complete` will likely result in a panic of the\nprogram.\n\n### Closure-like semantics\n\nThe closure-like syntax for generators alludes to the fact that they also have\nclosure-like semantics. Namely:\n\n* When created, a generator executes no code. A closure literal does not\n actually execute any of the closure's code on construction, and similarly a\n generator literal does not execute any code inside the generator when\n constructed.\n\n* Generators can capture outer variables by reference or by move, and this can\n be tweaked with the `move` keyword at the beginning of the closure. Like\n closures all generators will have an implicit environment which is inferred by\n the compiler. Outer variables can be moved into a generator for use as the\n generator progresses.\n\n* Generator literals produce a value with a unique type which implements the\n `std::ops::Generator` trait. This allows actual execution of the generator\n through the `Generator::resume` method as well as also naming it in return\n types and such.\n\n* Traits like `Send` and `Sync` are automatically implemented for a `Generator`\n depending on the captured variables of the environment. Unlike closures,\n generators also depend on variables live across suspension points. This means\n that although the ambient environment may be `Send` or `Sync`, the generator\n itself may not be due to internal variables live across `yield` points being\n not-`Send` or not-`Sync`. Note that generators do\n not implement traits like `Copy` or `Clone` automatically.\n\n* Whenever a generator is dropped it will drop all captured environment\n variables.\n\n### Generators as state machines\n\nIn the compiler, generators are currently compiled as state machines. Each\n`yield` expression will correspond to a different state that stores all live\nvariables over that suspension point. Resumption of a generator will dispatch on\nthe current state and then execute internally until a `yield` is reached, at\nwhich point all state is saved off in the generator and a value is returned.\n\nLet's take a look at an example to see what's going on here:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::Generator;\nuse std::pin::Pin;\n\nfn main() {\n let ret = \"foo\";\n let mut generator = move || {\n yield 1;\n return ret\n };\n\n Pin::new(&mut generator).resume(());\n Pin::new(&mut generator).resume(());\n}\n```\n\nThis generator literal will compile down to something similar to:\n\n```rust\n#![feature(arbitrary_self_types, generators, generator_trait)]\n\nuse std::ops::{Generator, GeneratorState};\nuse std::pin::Pin;\n\nfn main() {\n let ret = \"foo\";\n let mut generator = {\n enum __Generator {\n Start(&'static str),\n Yield1(&'static str),\n Done,\n }\n\n impl Generator for __Generator {\n type Yield = i32;\n type Return = &'static str;\n\n fn resume(mut self: Pin<&mut Self>, resume: ()) -> GeneratorState {\n use std::mem;\n match mem::replace(&mut *self, __Generator::Done) {\n __Generator::Start(s) => {\n *self = __Generator::Yield1(s);\n GeneratorState::Yielded(1)\n }\n\n __Generator::Yield1(s) => {\n *self = __Generator::Done;\n GeneratorState::Complete(s)\n }\n\n __Generator::Done => {\n panic!(\"generator resumed after completion\")\n }\n }\n }\n }\n\n __Generator::Start(ret)\n };\n\n Pin::new(&mut generator).resume(());\n Pin::new(&mut generator).resume(());\n}\n```\n\nNotably here we can see that the compiler is generating a fresh type,\n`__Generator` in this case. This type has a number of states (represented here\nas an `enum`) corresponding to each of the conceptual states of the generator.\nAt the beginning we're closing over our outer variable `foo` and then that\nvariable is also live over the `yield` point, so it's stored in both states.\n\nWhen the generator starts it'll immediately yield 1, but it saves off its state\njust before it does so indicating that it has reached the yield point.

The syntax isn't final, either. We may need an alternative syntax for Rust 2015 because, in Rust 2015, expressions like `[e; dyn(1)]` would be ambiguous. One possible alternative proposed in the RFC is `[e; n]`: if `n` captures one or more local variables, then it is considered as `[e; dyn n]`.\n\n## Advisory on stack usage\n\nIt's advised not to casually use the `#![feature(unsized_locals)]` feature. Typical use-cases are:\n\n- When you need a by-value trait objects.\n- When you really need a fast allocation of small temporary arrays.\n\nAnother pitfall is repetitive allocation and temporaries. Currently the compiler simply extends the stack frame every time it encounters an unsized assignment. So for example, the code\n\n```rust\n#![feature(unsized_locals)]\n\nfn main() {\n let x: Box<[i32]> = Box::new([1, 2, 3, 4, 5]);\n let _x = {{{{{{{{{{*x}}}}}}}}}};\n}\n```\n\nand the code\n\n```rust\n#![feature(unsized_locals)]\n\nfn main() {\n for _ in 0..10 {\n let x: Box<[i32]> = Box::new([1, 2, 3, 4, 5]);\n let _x = *x;\n }\n}\n```\n\nwill unnecessarily extend the stack frame.\n" } , LintCompletion { label : "or_patterns" , description : "# `or_patterns`\n\nThe tracking issue for this feature is: [#54883]\n\n[#54883]: https://github.com/rust-lang/rust/issues/54883\n\n------------------------\n\nThe `or_pattern` language feature allows `|` to be arbitrarily nested within\na pattern, for example, `Some(A(0) | B(1 | 2))` becomes a valid pattern.\n\n## Examples\n\n```rust,ignore\n#![feature(or_patterns)]\n\npub enum Foo {\n Bar,\n Baz,\n Quux,\n}\n\npub fn example(maybe_foo: Option) {\n match maybe_foo {\n Some(Foo::Bar | Foo::Baz) => {\n println!(\"The value contained `Bar` or `Baz`\");\n }\n Some(_) => {\n println!(\"The value did not contain `Bar` or `Baz`\");\n }\n None => {\n println!(\"The value was `None`\");\n }\n }\n}\n```\n" } , LintCompletion { label : "member_constraints" , description : "# `member_constraints`\n\nThe tracking issue for this feature is: [#61997]\n\n[#61997]: https://github.com/rust-lang/rust/issues/61997\n\n------------------------\n\nThe `member_constraints` feature gate lets you use `impl Trait` syntax with\nmultiple unrelated lifetime parameters.\n\nA simple example is:\n\n```rust\n#![feature(member_constraints)]\n\ntrait Trait<'a, 'b> { }\nimpl Trait<'_, '_> for T {}\n\nfn foo<'a, 'b>(x: &'a u32, y: &'b u32) -> impl Trait<'a, 'b> {\n (x, y)\n}\n\nfn main() { }\n```\n\nWithout the `member_constraints` feature gate, the above example is an\nerror because both `'a` and `'b` appear in the impl Trait bounds, but\nneither outlives the other.\n" } , LintCompletion { label : "optin_builtin_traits" , description : "# `optin_builtin_traits`\n\nThe tracking issue for this feature is [#13231] \n\n[#13231]: https://github.com/rust-lang/rust/issues/13231\n\n----\n\nThe `optin_builtin_traits` feature gate allows you to define auto traits.\n\nAuto traits, like [`Send`] or [`Sync`] in the standard library, are marker traits\nthat are automatically implemented for every type, unless the type, or a type it contains, \nhas explicitly opted out via a negative impl.

These automatic impls contain a where clause for each field\nof the form `T: AutoTrait`, where `T` is the type of the field and\n`AutoTrait` is the auto trait in question. As an example, consider the\nstruct `List` and the auto trait `Send`:\n\n```rust\nstruct List {\n data: T,\n next: Option>>,\n}\n```\n\nPresuming that there is no explicit impl of `Send` for `List`, the\ncompiler will supply an automatic impl of the form:\n\n```rust\nstruct List {\n data: T,\n next: Option>>,\n}\n\nunsafe impl Send for List\nwhere\n T: Send, // from the field `data`\n Option>>: Send, // from the field `next`\n{ }\n```\n\nExplicit impls may be either positive or negative. They take the form:\n\n```rust,ignore\nimpl<...> AutoTrait for StructName<..> { }\nimpl<...> !AutoTrait for StructName<..> { }\n```\n\n## Coinduction: Auto traits permit cyclic matching\n\nUnlike ordinary trait matching, auto traits are **coinductive**. This\nmeans, in short, that cycles which occur in trait matching are\nconsidered ok. As an example, consider the recursive struct `List`\nintroduced in the previous section. In attempting to determine whether\n`List: Send`, we would wind up in a cycle: to apply the impl, we must\nshow that `Option>: Send`, which will in turn require\n`Box: Send` and then finally `List: Send` again. Under ordinary\ntrait matching, this cycle would be an error, but for an auto trait it\nis considered a successful match.\n\n## Items\n\nAuto traits cannot have any trait items, such as methods or associated types. This ensures that we can generate default implementations.\n\n## Supertraits\n\nAuto traits cannot have supertraits.

The marker is the attribute `#[lang = \"...\"]` and there are\nvarious different values of `...`, i.e. various different 'lang\nitems'.\n\nFor example, `Box` pointers require two lang items, one for allocation\nand one for deallocation. A freestanding program that uses the `Box`\nsugar for dynamic allocations via `malloc` and `free`:\n\n```rust,ignore\n#![feature(lang_items, box_syntax, start, libc, core_intrinsics)]\n#![no_std]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\nextern crate libc;\n\n#[lang = \"owned_box\"]\npub struct Box(*mut T);\n\n#[lang = \"exchange_malloc\"]\nunsafe fn allocate(size: usize, _align: usize) -> *mut u8 {\n let p = libc::malloc(size as libc::size_t) as *mut u8;\n\n // Check if `malloc` failed:\n if p as usize == 0 {\n intrinsics::abort();\n }\n\n p\n}\n\n#[lang = \"box_free\"]\nunsafe fn box_free(ptr: *mut T) {\n libc::free(ptr as *mut libc::c_void)\n}\n\n#[start]\nfn main(_argc: isize, _argv: *const *const u8) -> isize {\n let _x = box 1;\n\n 0\n}\n\n#[lang = \"eh_personality\"] extern fn rust_eh_personality() {}\n#[lang = \"panic_impl\"] extern fn rust_begin_panic(info: &PanicInfo) -> ! { unsafe { intrinsics::abort() } }\n#[no_mangle] pub extern fn rust_eh_register_frames () {}\n#[no_mangle] pub extern fn rust_eh_unregister_frames () {}\n```\n\nNote the use of `abort`: the `exchange_malloc` lang item is assumed to\nreturn a valid pointer, and so needs to do the check internally.\n\nOther features provided by lang items include:\n\n- overloadable operators via traits: the traits corresponding to the\n `==`, `<`, dereferencing (`*`) and `+` (etc.) operators are all\n marked with lang items; those specific four are `eq`, `ord`,\n `deref`, and `add` respectively.\n- stack unwinding and general failure; the `eh_personality`,\n `panic` and `panic_bounds_checks` lang items.\n- the traits in `std::marker` used to indicate types of\n various kinds; lang items `send`, `sync` and `copy`.\n- the marker types and variance indicators found in\n `std::marker`; lang items `covariant_type`,\n `contravariant_lifetime`, etc.\n\nLang items are loaded lazily by the compiler; e.g. if one never uses\n`Box` then there is no need to define functions for `exchange_malloc`\nand `box_free`. `rustc` will emit an error when an item is needed\nbut not found in the current crate or any that it depends on.\n\nMost lang items are defined by `libcore`, but if you're trying to build\nan executable without the standard library, you'll run into the need\nfor lang items. The rest of this page focuses on this use-case, even though\nlang items are a bit broader than that.\n\n### Using libc\n\nIn order to build a `#[no_std]` executable we will need libc as a dependency.\nWe can specify this using our `Cargo.toml` file:\n\n```toml\n[dependencies]\nlibc = { version = \"0.2.14\", default-features = false }\n```\n\nNote that the default features have been disabled. This is a critical step -\n**the default features of libc include the standard library and so must be\ndisabled.**\n\n### Writing an executable without stdlib\n\nControlling the entry point is possible in two ways: the `#[start]` attribute,\nor overriding the default shim for the C `main` function with your own.\n\nThe function marked `#[start]` is passed the command line parameters\nin the same format as C:\n\n```rust,ignore\n#![feature(lang_items, core_intrinsics)]\n#![feature(start)]\n#![no_std]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\n// Pull in the system libc library for what crt0.o likely requires.\nextern crate libc;\n\n// Entry point for this program.\n#[start]\nfn start(_argc: isize, _argv: *const *const u8) -> isize {\n 0\n}\n\n// These functions are used by the compiler, but not\n// for a bare-bones hello world. These are normally\n// provided by libstd.\n#[lang = \"eh_personality\"]\n#[no_mangle]\npub extern fn rust_eh_personality() {\n}\n\n#[lang = \"panic_impl\"]\n#[no_mangle]\npub extern fn rust_begin_panic(info: &PanicInfo) -> ! {\n unsafe { intrinsics::abort() }\n}\n```\n\nTo override the compiler-inserted `main` shim, one has to disable it\nwith `#![no_main]` and then create the appropriate symbol with the\ncorrect ABI and the correct name, which requires overriding the\ncompiler's name mangling too:\n\n```rust,ignore\n#![feature(lang_items, core_intrinsics)]\n#![feature(start)]\n#![no_std]\n#![no_main]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\n// Pull in the system libc library for what crt0.o likely requires.\nextern crate libc;\n\n// Entry point for this program.\n#[no_mangle] // ensure that this symbol is called `main` in the output\npub extern fn main(_argc: i32, _argv: *const *const u8) -> i32 {\n 0\n}\n\n// These functions are used by the compiler, but not\n// for a bare-bones hello world.

You may observe this via linker error messages\nsuch as \"```undefined reference to `__rust_probestack'```\".\n\n## More about the language items\n\nThe compiler currently makes a few assumptions about symbols which are\navailable in the executable to call. Normally these functions are provided by\nthe standard library, but without it you must define your own. These symbols\nare called \"language items\", and they each have an internal name, and then a\nsignature that an implementation must conform to.\n\nThe first of these functions, `rust_eh_personality`, is used by the failure\nmechanisms of the compiler. This is often mapped to GCC's personality function\n(see the [libstd implementation][unwind] for more information), but crates\nwhich do not trigger a panic can be assured that this function is never\ncalled.

Negative impls are a commitment not to implement the given trait for the named types.\n\n## Orphan and overlap rules\n\nNegative impls must obey the same orphan rules as a positive impl. This implies you cannot add a negative impl for types defined in upstream crates and so forth.\n\nSimilarly, negative impls cannot overlap with positive impls, again using the same \"overlap\" check that we ordinarily use to determine if two impls overlap. (Note that positive impls typically cannot overlap with one another either, except as permitted by specialization.)\n\n## Interaction with auto traits\n\nDeclaring a negative impl `impl !SomeAutoTrait for SomeType` for an\nauto-trait serves two purposes:\n\n* as with any trait, it declares that `SomeType` will never implement `SomeAutoTrait`;\n* it disables the automatic `SomeType: SomeAutoTrait` impl that would otherwise have been generated.\n\nNote that, at present, there is no way to indicate that a given type\ndoes not implement an auto trait *but that it may do so in the\nfuture*. For ordinary types, this is done by simply not declaring any\nimpl at all, but that is not an option for auto traits. A workaround\nis that one could embed a marker type as one of the fields, where the\nmarker type is `!AutoTrait`.\n\n## Immediate uses\n\nNegative impls are used to declare that `&T: !DerefMut` and `&mut T: !Clone`, as required to fix the soundness of `Pin` described in [#66544](https://github.com/rust-lang/rust/issues/66544).\n\nThis serves two purposes:\n\n* For proving the correctness of unsafe code, we can use that impl as evidence that no `DerefMut` or `Clone` impl exists.\n* It prevents downstream crates from creating such impls.\n" } , LintCompletion { label : "abi_ptx" , description : "# `abi_ptx`\n\nThe tracking issue for this feature is: [#38788]\n\n[#38788]: https://github.com/rust-lang/rust/issues/38788\n\n------------------------\n\nWhen emitting PTX code, all vanilla Rust functions (`fn`) get translated to\n\"device\" functions.

This is\ngenerally unwanted unless you are building another plugin.\n\nThe usual practice is to put compiler plugins in their own crate, separate from\nany `macro_rules!` macros or ordinary Rust code meant to be used by consumers\nof a library.\n\n# Lint plugins\n\nPlugins can extend [Rust's lint\ninfrastructure](../../reference/attributes/diagnostics.md#lint-check-attributes) with\nadditional checks for code style, safety, etc. Now let's write a plugin\n[`lint-plugin-test.rs`](https://github.com/rust-lang/rust/blob/master/src/test/ui-fulldeps/auxiliary/lint-plugin-test.rs)\nthat warns about any item named `lintme`.\n\n```rust,ignore\n#![feature(plugin_registrar)]\n#![feature(box_syntax, rustc_private)]\n\nextern crate rustc_ast;\n\n// Load rustc as a plugin to get macros\nextern crate rustc_driver;\n#[macro_use]\nextern crate rustc_lint;\n#[macro_use]\nextern crate rustc_session;\n\nuse rustc_driver::plugin::Registry;\nuse rustc_lint::{EarlyContext, EarlyLintPass, LintArray, LintContext, LintPass};\nuse rustc_ast::ast;\ndeclare_lint!(TEST_LINT, Warn, \"Warn about items named 'lintme'\");\n\ndeclare_lint_pass!(Pass => [TEST_LINT]);\n\nimpl EarlyLintPass for Pass {\n fn check_item(&mut self, cx: &EarlyContext, it: &ast::Item) {\n if it.ident.name.as_str() == \"lintme\" {\n cx.lint(TEST_LINT, |lint| {\n lint.build(\"item is named 'lintme'\").set_span(it.span).emit()\n });\n }\n }\n}\n\n#[plugin_registrar]\npub fn plugin_registrar(reg: &mut Registry) {\n reg.lint_store.register_lints(&[&TEST_LINT]);\n reg.lint_store.register_early_pass(|| box Pass);\n}\n```\n\nThen code like\n\n```rust,ignore\n#![feature(plugin)]\n#![plugin(lint_plugin_test)]\n\nfn lintme() { }\n```\n\nwill produce a compiler warning:\n\n```txt\nfoo.rs:4:1: 4:16 warning: item is named 'lintme', #[warn(test_lint)] on by default\nfoo.rs:4 fn lintme() { }\n ^~~~~~~~~~~~~~~\n```\n\nThe components of a lint plugin are:\n\n* one or more `declare_lint!` invocations, which define static `Lint` structs;\n\n* a struct holding any state needed by the lint pass (here, none);\n\n* a `LintPass`\n implementation defining how to check each syntax element. A single\n `LintPass` may call `span_lint` for several different `Lint`s, but should\n register them all through the `get_lints` method.\n\nLint passes are syntax traversals, but they run at a late stage of compilation\nwhere type information is available. `rustc`'s [built-in\nlints](https://github.com/rust-lang/rust/blob/master/src/librustc_session/lint/builtin.rs)\nmostly use the same infrastructure as lint plugins, and provide examples of how\nto access type information.\n\nLints defined by plugins are controlled by the usual [attributes and compiler\nflags](../../reference/attributes/diagnostics.md#lint-check-attributes), e.g.\n`#[allow(test_lint)]` or `-A test-lint`. These identifiers are derived from the\nfirst argument to `declare_lint!`, with appropriate case and punctuation\nconversion.\n\nYou can run `rustc -W help foo.rs` to see a list of lints known to `rustc`,\nincluding those provided by plugins loaded by `foo.rs`.\n" } , LintCompletion { label : "concat_idents" , description : "# `concat_idents`\n\nThe tracking issue for this feature is: [#29599]\n\n[#29599]: https://github.com/rust-lang/rust/issues/29599\n\n------------------------\n\nThe `concat_idents` feature adds a macro for concatenating multiple identifiers\ninto one identifier.\n\n## Examples\n\n```rust\n#![feature(concat_idents)]\n\nfn main() {\n fn foobar() -> u32 { 23 }\n let f = concat_idents!(foo, bar);\n assert_eq!(f(), 23);\n}\n```" } , LintCompletion { label : "update_panic_count" , description : "# `update_panic_count`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "fn_traits" , description : "# `fn_traits`\n\nThe tracking issue for this feature is [#29625]\n\nSee Also: [`unboxed_closures`](../language-features/unboxed-closures.md)\n\n[#29625]: https://github.com/rust-lang/rust/issues/29625\n\n----\n\nThe `fn_traits` feature allows for implementation of the [`Fn*`] traits\nfor creating custom closure-like types.\n\n[`Fn*`]: https://doc.rust-lang.org/std/ops/trait.Fn.html\n\n```rust\n#![feature(unboxed_closures)]\n#![feature(fn_traits)]\n\nstruct Adder {\n a: u32\n}\n\nimpl FnOnce<(u32, )> for Adder {\n type Output = u32;\n extern \"rust-call\" fn call_once(self, b: (u32, )) -> Self::Output {\n self.a + b.0\n }\n}\n\nfn main() {\n let adder = Adder { a: 3 };\n assert_eq!(adder(2), 5);\n}\n```\n" } , LintCompletion { label : "try_trait" , description : "# `try_trait`\n\nThe tracking issue for this feature is: [#42327]\n\n[#42327]: https://github.com/rust-lang/rust/issues/42327\n\n------------------------\n\nThis introduces a new trait `Try` for extending the `?` operator to types\nother than `Result` (a part of [RFC 1859]).

The macro is a no-frills\ninterface to LLVM's concept of [module-level inline assembly]. That is,\nall caveats applicable to LLVM's module-level inline assembly apply\nto `global_asm!`.\n\n[module-level inline assembly]: http://llvm.org/docs/LangRef.html#module-level-inline-assembly\n\n`global_asm!` fills a role not currently satisfied by either `asm!`\nor `#[naked]` functions. The programmer has _all_ features of the\nassembler at their disposal. The linker will expect to resolve any\nsymbols defined in the inline assembly, modulo any symbols marked as\nexternal. It also means syntax for directives and assembly follow the\nconventions of the assembler in your toolchain.\n\nA simple usage looks like this:\n\n```rust,ignore\n# #![feature(global_asm)]\n# you also need relevant target_arch cfgs\nglobal_asm!(include_str!(\"something_neato.s\"));\n```\n\nAnd a more complicated usage looks like this:\n\n```rust,ignore\n# #![feature(global_asm)]\n# #![cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n\npub mod sally {\n global_asm!(r#\"\n .global foo\n foo:\n jmp baz\n \"#);\n\n #[no_mangle]\n pub unsafe extern \"C\" fn baz() {}\n}\n\n// the symbols `foo` and `bar` are global, no matter where\n// `global_asm!` was used.\nextern \"C\" {\n fn foo();\n fn bar();\n}\n\npub mod harry {\n global_asm!(r#\"\n .global bar\n bar:\n jmp quux\n \"#);\n\n #[no_mangle]\n pub unsafe extern \"C\" fn quux() {}\n}\n```\n\nYou may use `global_asm!` multiple times, anywhere in your crate, in\nwhatever way suits you. The effect is as if you concatenated all\nusages and placed the larger, single usage in the crate root.\n\n------------------------\n\nIf you don't need quite as much power and flexibility as\n`global_asm!` provides, and you don't mind restricting your inline\nassembly to `fn` bodies only, you might try the\n[asm](asm.md) feature instead.\n" } , LintCompletion { label : "sort_internals" , description : "# `sort_internals`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "test" , description : "# `test`\n\nThe tracking issue for this feature is: None.\n\n------------------------\n\nThe internals of the `test` crate are unstable, behind the `test` flag. The\nmost widely used part of the `test` crate are benchmark tests, which can test\nthe performance of your code. Let's make our `src/lib.rs` look like this\n(comments elided):\n\n```rust,ignore\n#![feature(test)]\n\nextern crate test;\n\npub fn add_two(a: i32) -> i32 {\n a + 2\n}\n\n#[cfg(test)]\nmod tests {\n use super::*;\n use test::Bencher;\n\n #[test]\n fn it_works() {\n assert_eq!(4, add_two(2));\n }\n\n #[bench]\n fn bench_add_two(b: &mut Bencher) {\n b.iter(|| add_two(2));\n }\n}\n```\n\nNote the `test` feature gate, which enables this unstable feature.\n\nWe've imported the `test` crate, which contains our benchmarking support.\nWe have a new function as well, with the `bench` attribute. Unlike regular\ntests, which take no arguments, benchmark tests take a `&mut Bencher`. This\n`Bencher` provides an `iter` method, which takes a closure. This closure\ncontains the code we'd like to benchmark.\n\nWe can run benchmark tests with `cargo bench`:\n\n```bash\n$ cargo bench\n Compiling adder v0.0.1 (file:///home/steve/tmp/adder)\n Running target/release/adder-91b3e234d4ed382a\n\nrunning 2 tests\ntest tests::it_works ... ignored\ntest tests::bench_add_two ... bench: 1 ns/iter (+/- 0)\n\ntest result: ok. 0 passed; 0 failed; 1 ignored; 1 measured\n```\n\nOur non-benchmark test was ignored. You may have noticed that `cargo bench`\ntakes a bit longer than `cargo test`. This is because Rust runs our benchmark\na number of times, and then takes the average. Because we're doing so little\nwork in this example, we have a `1 ns/iter (+/- 0)`, but this would show\nthe variance if there was one.\n\nAdvice on writing benchmarks:\n\n\n* Move setup code outside the `iter` loop; only put the part you want to measure inside\n* Make the code do \"the same thing\" on each iteration; do not accumulate or change state\n* Make the outer function idempotent too; the benchmark runner is likely to run\n it many times\n* Make the inner `iter` loop short and fast so benchmark runs are fast and the\n calibrator can adjust the run-length at fine resolution\n* Make the code in the `iter` loop do something simple, to assist in pinpointing\n performance improvements (or regressions)\n\n## Gotcha: optimizations\n\nThere's another tricky part to writing benchmarks: benchmarks compiled with\noptimizations activated can be dramatically changed by the optimizer so that\nthe benchmark is no longer benchmarking what one expects. For example, the\ncompiler might recognize that some calculation has no external effects and\nremove it entirely.\n\n```rust,ignore\n#![feature(test)]\n\nextern crate test;\nuse test::Bencher;\n\n#[bench]\nfn bench_xor_1000_ints(b: &mut Bencher) {\n b.iter(|| {\n (0..1000).fold(0, |old, new| old ^ new);\n });\n}\n```\n\ngives the following results\n\n```text\nrunning 1 test\ntest bench_xor_1000_ints ... bench: 0 ns/iter (+/- 0)\n\ntest result: ok. 0 passed; 0 failed; 0 ignored; 1 measured\n```\n\nThe benchmarking runner offers two ways to avoid this. Either, the closure that\nthe `iter` method receives can return an arbitrary value which forces the\noptimizer to consider the result used and ensures it cannot remove the\ncomputation entirely. This could be done for the example above by adjusting the\n`b.iter` call to\n\n```rust\n# struct X;\n# impl X { fn iter(&self, _: F) where F: FnMut() -> T {} } let b = X;\nb.iter(|| {\n // Note lack of `;` (could also use an explicit `return`).\n (0..1000).fold(0, |old, new| old ^ new)\n});\n```\n\nOr, the other option is to call the generic `test::black_box` function, which\nis an opaque \"black box\" to the optimizer and so forces it to consider any\nargument as used.\n\n```rust\n#![feature(test)]\n\nextern crate test;\n\n# fn main() {\n# struct X;\n# impl X { fn iter(&self, _: F) where F: FnMut() -> T {} } let b = X;\nb.iter(|| {\n let n = test::black_box(1000);\n\n (0..n).fold(0, |a, b| a ^ b)\n})\n# }\n```\n\nNeither of these read or modify the value, and are very cheap for small values.\nLarger values can be passed indirectly to reduce overhead (e.g.\n`black_box(&huge_struct)`).\n\nPerforming either of the above changes gives the following benchmarking results\n\n```text\nrunning 1 test\ntest bench_xor_1000_ints ... bench: 131 ns/iter (+/- 3)\n\ntest result: ok. 0 passed; 0 failed; 0 ignored; 1 measured\n```\n\nHowever, the optimizer can still modify a testcase in an undesirable manner\neven when using either of the above.\n" } , LintCompletion { label : "windows_stdio" , description : "# `windows_stdio`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "allocator_api" , description : "# `allocator_api`\n\nThe tracking issue for this feature is [#32838]\n\n[#32838]: https://github.com/rust-lang/rust/issues/32838\n\n------------------------\n\nSometimes you want the memory for one collection to use a different\nallocator than the memory for another collection.

Rust supports using inline\nassembly to do this via the `asm!` macro.\n\n# Guide-level explanation\n[guide-level-explanation]: #guide-level-explanation\n\nRust provides support for inline assembly via the `asm!` macro.\nIt can be used to embed handwritten assembly in the assembly output generated by the compiler.\nGenerally this should not be necessary, but might be where the required performance or timing\ncannot be otherwise achieved. Accessing low level hardware primitives, e.g. in kernel code, may also demand this functionality.\n\n> **Note**: the examples here are given in x86/x86-64 assembly, but other architectures are also supported.\n\nInline assembly is currently supported on the following architectures:\n- x86 and x86-64\n- ARM\n- AArch64\n- RISC-V\n- NVPTX\n- Hexagon\n\n## Basic usage\n\nLet us start with the simplest possible example:\n\n```rust,allow_fail\n# #![feature(asm)]\nunsafe {\n asm!(\"nop\");\n}\n```\n\nThis will insert a NOP (no operation) instruction into the assembly generated by the compiler.\nNote that all `asm!` invocations have to be inside an `unsafe` block, as they could insert\narbitrary instructions and break various invariants. The instructions to be inserted are listed\nin the first argument of the `asm!` macro as a string literal.\n\n## Inputs and outputs\n\nNow inserting an instruction that does nothing is rather boring. Let us do something that\nactually acts on data:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet x: u64;\nunsafe {\n asm!(\"mov {}, 5\", out(reg) x);\n}\nassert_eq!(x, 5);\n```\n\nThis will write the value `5` into the `u64` variable `x`.\nYou can see that the string literal we use to specify instructions is actually a template string.\nIt is governed by the same rules as Rust [format strings][format-syntax].\nThe arguments that are inserted into the template however look a bit different then you may\nbe familiar with. First we need to specify if the variable is an input or an output of the\ninline assembly. In this case it is an output. We declared this by writing `out`.\nWe also need to specify in what kind of register the assembly expects the variable.\nIn this case we put it in an arbitrary general purpose register by specifying `reg`.\nThe compiler will choose an appropriate register to insert into\nthe template and will read the variable from there after the inline assembly finishes executing.\n\nLet us see another example that also uses an input:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet i: u64 = 3;\nlet o: u64;\nunsafe {\n asm!(\n \"mov {0}, {1}\",\n \"add {0}, {number}\",\n out(reg) o,\n in(reg) i,\n number = const 5,\n );\n}\nassert_eq!(o, 8);\n```\n\nThis will add `5` to the input in variable `i` and write the result to variable `o`.\nThe particular way this assembly does this is first copying the value from `i` to the output,\nand then adding `5` to it.\n\nThe example shows a few things:\n\nFirst, we can see that `asm!` allows multiple template string arguments; each\none is treated as a separate line of assembly code, as if they were all joined\ntogether with newlines between them. This makes it easy to format assembly\ncode.\n\nSecond, we can see that inputs are declared by writing `in` instead of `out`.\n\nThird, one of our operands has a type we haven't seen yet, `const`.\nThis tells the compiler to expand this argument to value directly inside the assembly template.\nThis is only possible for constants and literals.\n\nFourth, we can see that we can specify an argument number, or name as in any format string.\nFor inline assembly templates this is particularly useful as arguments are often used more than once.\nFor more complex inline assembly using this facility is generally recommended, as it improves\nreadability, and allows reordering instructions without changing the argument order.\n\nWe can further refine the above example to avoid the `mov` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut x: u64 = 3;\nunsafe {\n asm!(\"add {0}, {number}\", inout(reg) x, number = const 5);\n}\nassert_eq!(x, 8);\n```\n\nWe can see that `inout` is used to specify an argument that is both input and output.\nThis is different from specifying an input and output separately in that it is guaranteed to assign both to the same register.\n\nIt is also possible to specify different variables for the input and output parts of an `inout` operand:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet x: u64 = 3;\nlet y: u64;\nunsafe {\n asm!(\"add {0}, {number}\", inout(reg) x => y, number = const 5);\n}\nassert_eq!(y, 8);\n```\n\n## Late output operands\n\nThe Rust compiler is conservative with its allocation of operands. It is assumed that an `out`\ncan be written at any time, and can therefore not share its location with any other argument.\nHowever, to guarantee optimal performance it is important to use as few registers as possible,\nso they won't have to be saved and reloaded around the inline assembly block.\nTo achieve this Rust provides a `lateout` specifier. This can be used on any output that is\nwritten only after all inputs have been consumed.\nThere is also a `inlateout` variant of this specifier.\n\nHere is an example where `inlateout` *cannot* be used:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nlet c: u64 = 4;\nunsafe {\n asm!(\n \"add {0}, {1}\",\n \"add {0}, {2}\",\n inout(reg) a,\n in(reg) b,\n in(reg) c,\n );\n}\nassert_eq!(a, 12);\n```\n\nHere the compiler is free to allocate the same register for inputs `b` and `c` since it knows they have the same value. However it must allocate a separate register for `a` since it uses `inout` and not `inlateout`. If `inlateout` was used, then `a` and `c` could be allocated to the same register, in which case the first instruction to overwrite the value of `c` and cause the assembly code to produce the wrong result.\n\nHowever the following example can use `inlateout` since the output is only modified after all input registers have been read:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nunsafe {\n asm!(\"add {0}, {1}\", inlateout(reg) a, in(reg) b);\n}\nassert_eq!(a, 8);\n```\n\nAs you can see, this assembly fragment will still work correctly if `a` and `b` are assigned to the same register.\n\n## Explicit register operands\n\nSome instructions require that the operands be in a specific register.\nTherefore, Rust inline assembly provides some more specific constraint specifiers.\nWhile `reg` is generally available on any architecture, these are highly architecture specific. E.g. for x86 the general purpose registers `eax`, `ebx`, `ecx`, `edx`, `ebp`, `esi`, and `edi`\namong others can be addressed by their name.\n\n```rust,allow_fail,no_run\n# #![feature(asm)]\nlet cmd = 0xd1;\nunsafe {\n asm!(\"out 0x64, eax\", in(\"eax\") cmd);\n}\n```\n\nIn this example we call the `out` instruction to output the content of the `cmd` variable\nto port `0x64`. Since the `out` instruction only accepts `eax` (and its sub registers) as operand\nwe had to use the `eax` constraint specifier.\n\nNote that unlike other operand types, explicit register operands cannot be used in the template string: you can't use `{}` and should write the register name directly instead. Also, they must appear at the end of the operand list after all other operand types.\n\nConsider this example which uses the x86 `mul` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nfn mul(a: u64, b: u64) -> u128 {\n let lo: u64;\n let hi: u64;\n\n unsafe {\n asm!(\n // The x86 mul instruction takes rax as an implicit input and writes\n // the 128-bit result of the multiplication to rax:rdx.\n \"mul {}\",\n in(reg) a,\n inlateout(\"rax\") b => lo,\n lateout(\"rdx\") hi\n );\n }\n\n ((hi as u128) << 64) + lo as u128\n}\n```\n\nThis uses the `mul` instruction to multiply two 64-bit inputs with a 128-bit result.\nThe only explicit operand is a register, that we fill from the variable `a`.\nThe second operand is implicit, and must be the `rax` register, which we fill from the variable `b`.\nThe lower 64 bits of the result are stored in `rax` from which we fill the variable `lo`.\nThe higher 64 bits are stored in `rdx` from which we fill the variable `hi`.\n\n## Clobbered registers\n\nIn many cases inline assembly will modify state that is not needed as an output.\nUsually this is either because we have to use a scratch register in the assembly,\nor instructions modify state that we don't need to further examine.\nThis state is generally referred to as being \"clobbered\".\nWe need to tell the compiler about this since it may need to save and restore this state\naround the inline assembly block.\n\n```rust,allow_fail\n# #![feature(asm)]\nlet ebx: u32;\nlet ecx: u32;\n\nunsafe {\n asm!(\n \"cpuid\",\n // EAX 4 selects the \"Deterministic Cache Parameters\" CPUID leaf\n inout(\"eax\") 4 => _,\n // ECX 0 selects the L0 cache information.\n inout(\"ecx\") 0 => ecx,\n lateout(\"ebx\") ebx,\n lateout(\"edx\") _,\n );\n}\n\nprintln!(\n \"L1 Cache: {}\",\n ((ebx >> 22) + 1) * (((ebx >> 12) & 0x3ff) + 1) * ((ebx & 0xfff) + 1) * (ecx + 1)\n);\n```\n\nIn the example above we use the `cpuid` instruction to get the L1 cache size.\nThis instruction writes to `eax`, `ebx`, `ecx`, and `edx`, but for the cache size we only care about the contents of `ebx` and `ecx`.\n\nHowever we still need to tell the compiler that `eax` and `edx` have been modified so that it can save any values that were in these registers before the asm. This is done by declaring these as outputs but with `_` instead of a variable name, which indicates that the output value is to be discarded.\n\nThis can also be used with a general register class (e.g. `reg`) to obtain a scratch register for use inside the asm code:\n\n```rust,allow_fail\n# #![feature(asm)]\n// Multiply x by 6 using shifts and adds\nlet mut x: u64 = 4;\nunsafe {\n asm!(\n \"mov {tmp}, {x}\",\n \"shl {tmp}, 1\",\n \"shl {x}, 2\",\n \"add {x}, {tmp}\",\n x = inout(reg) x,\n tmp = out(reg) _,\n );\n}\nassert_eq!(x, 4 * 6);\n```\n\n## Symbol operands\n\nA special operand type, `sym`, allows you to use the symbol name of a `fn` or `static` in inline assembly code.\nThis allows you to call a function or access a global variable without needing to keep its address in a register.\n\n```rust,allow_fail\n# #![feature(asm)]\nextern \"C\" fn foo(arg: i32) {\n println!(\"arg = {}\", arg);\n}\n\nfn call_foo(arg: i32) {\n unsafe {\n asm!(\n \"call {}\",\n sym foo,\n // 1st argument in rdi, which is caller-saved\n inout(\"rdi\") arg => _,\n // All caller-saved registers must be marked as clobberred\n out(\"rax\") _, out(\"rcx\") _, out(\"rdx\") _, out(\"rsi\") _,\n out(\"r8\") _, out(\"r9\") _, out(\"r10\") _, out(\"r11\") _,\n out(\"xmm0\") _, out(\"xmm1\") _, out(\"xmm2\") _, out(\"xmm3\") _,\n out(\"xmm4\") _, out(\"xmm5\") _, out(\"xmm6\") _, out(\"xmm7\") _,\n out(\"xmm8\") _, out(\"xmm9\") _, out(\"xmm10\") _, out(\"xmm11\") _,\n out(\"xmm12\") _, out(\"xmm13\") _, out(\"xmm14\") _, out(\"xmm15\") _,\n )\n }\n}\n```\n\nNote that the `fn` or `static` item does not need to be public or `#[no_mangle]`:\nthe compiler will automatically insert the appropriate mangled symbol name into the assembly code.\n\n## Register template modifiers\n\nIn some cases, fine control is needed over the way a register name is formatted when inserted into the template string. This is needed when an architecture's assembly language has several names for the same register, each typically being a \"view\" over a subset of the register (e.g. the low 32 bits of a 64-bit register).\n\nBy default the compiler will always choose the name that refers to the full register size (e.g. `rax` on x86-64, `eax` on x86, etc).\n\nThis default can be overriden by using modifiers on the template string operands, just like you would with format strings:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut x: u16 = 0xab;\n\nunsafe {\n asm!(\"mov {0:h}, {0:l}\", inout(reg_abcd) x);\n}\n\nassert_eq!(x, 0xabab);\n```\n\nIn this example, we use the `reg_abcd` register class to restrict the register allocator to the 4 legacy x86 register (`ax`, `bx`, `cx`, `dx`) of which the first two bytes can be addressed independently.\n\nLet us assume that the register allocator has chosen to allocate `x` in the `ax` register.\nThe `h` modifier will emit the register name for the high byte of that register and the `l` modifier will emit the register name for the low byte. The asm code will therefore be expanded as `mov ah, al` which copies the low byte of the value into the high byte.\n\nIf you use a smaller data type (e.g. `u16`) with an operand and forget the use template modifiers, the compiler will emit a warning and suggest the correct modifier to use.\n\n## Options\n\nBy default, an inline assembly block is treated the same way as an external FFI function call with a custom calling convention: it may read/write memory, have observable side effects, etc. However in many cases, it is desirable to give the compiler more information about what the assembly code is actually doing so that it can optimize better.\n\nLet's take our previous example of an `add` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nunsafe {\n asm!(\n \"add {0}, {1}\",\n inlateout(reg) a, in(reg) b,\n options(pure, nomem, nostack),\n );\n}\nassert_eq!(a, 8);\n```\n\nOptions can be provided as an optional final argument to the `asm!` macro. We specified three options here:\n- `pure` means that the asm code has no observable side effects and that its output depends only on its inputs. This allows the compiler optimizer to call the inline asm fewer times or even eliminate it entirely.\n- `nomem` means that the asm code does not read or write to memory. By default the compiler will assume that inline assembly can read or write any memory address that is accessible to it (e.g. through a pointer passed as an operand, or a global).\n- `nostack` means that the asm code does not push any data onto the stack. This allows the compiler to use optimizations such as the stack red zone on x86-64 to avoid stack pointer adjustments.\n\nThese allow the compiler to better optimize code using `asm!`, for example by eliminating pure `asm!` blocks whose outputs are not needed.\n\nSee the reference for the full list of available options and their effects.\n\n# Reference-level explanation\n[reference-level-explanation]: #reference-level-explanation\n\nInline assembler is implemented as an unsafe macro `asm!()`.\nThe first argument to this macro is a template string literal used to build the final assembly.\nThe following arguments specify input and output operands.\nWhen required, options are specified as the final argument.\n\nThe following ABNF specifies the general syntax:\n\n```ignore\ndir_spec := \"in\" / \"out\" / \"lateout\" / \"inout\" / \"inlateout\"\nreg_spec := / \"\"\noperand_expr := expr / \"_\" / expr \"=>\" expr / expr \"=>\" \"_\"\nreg_operand := dir_spec \"(\" reg_spec \")\" operand_expr\noperand := reg_operand / \"const\" const_expr / \"sym\" path\noption := \"pure\" / \"nomem\" / \"readonly\" / \"preserves_flags\" / \"noreturn\" / \"att_syntax\"\noptions := \"options(\" option *[\",\" option] [\",\"] \")\"\nasm := \"asm!(\" format_string *(\",\" format_string) *(\",\" [ident \"=\"] operand) [\",\" options] [\",\"] \")\"\n```\n\nThe macro will initially be supported only on ARM, AArch64, Hexagon, x86, x86-64 and RISC-V targets. Support for more targets may be added in the future. The compiler will emit an error if `asm!` is used on an unsupported target.\n\n[format-syntax]: https://doc.rust-lang.org/std/fmt/#syntax\n\n## Template string arguments\n\nThe assembler template uses the same syntax as [format strings][format-syntax] (i.e. placeholders are specified by curly braces). The corresponding arguments are accessed in order, by index, or by name. However, implicit named arguments (introduced by [RFC #2795][rfc-2795]) are not supported.\n\nAn `asm!` invocation may have one or more template string arguments; an `asm!` with multiple template string arguments is treated as if all the strings were concatenated with a `\\n` between them. The expected usage is for each template string argument to correspond to a line of assembly code. All template string arguments must appear before any other arguments.\n\nAs with format strings, named arguments must appear after positional arguments. Explicit register operands must appear at the end of the operand list, after named arguments if any.\n\nExplicit register operands cannot be used by placeholders in the template string. All other named and positional operands must appear at least once in the template string, otherwise a compiler error is generated.\n\nThe exact assembly code syntax is target-specific and opaque to the compiler except for the way operands are substituted into the template string to form the code passed to the assembler.\n\nThe 5 targets specified in this RFC (x86, ARM, AArch64, RISC-V, Hexagon) all use the assembly code syntax of the GNU assembler (GAS). On x86, the `.intel_syntax noprefix` mode of GAS is used by default. On ARM, the `.syntax unified` mode is used. These targets impose an additional restriction on the assembly code: any assembler state (e.g. the current section which can be changed with `.section`) must be restored to its original value at the end of the asm string. Assembly code that does not conform to the GAS syntax will result in assembler-specific behavior.\n\n[rfc-2795]: https://github.com/rust-lang/rfcs/pull/2795\n\n## Operand type\n\nSeveral types of operands are supported:\n\n* `in() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain the value of `` at the start of the asm code.\n - The allocated register must contain the same value at the end of the asm code (except if a `lateout` is allocated to the same register).\n* `out() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain an undefined value at the start of the asm code.\n - `` must be a (possibly uninitialized) place expression, to which the contents of the allocated register is written to at the end of the asm code.\n - An underscore (`_`) may be specified instead of an expression, which will cause the contents of the register to be discarded at the end of the asm code (effectively acting as a clobber).\n* `lateout() `\n - Identical to `out` except that the register allocator can reuse a register allocated to an `in`.\n - You should only write to the register after all inputs are read, otherwise you may clobber an input.\n* `inout() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain the value of `` at the start of the asm code.\n - `` must be a mutable initialized place expression, to which the contents of the allocated register is written to at the end of the asm code.\n* `inout() => `\n - Same as `inout` except that the initial value of the register is taken from the value of ``.\n - `` must be a (possibly uninitialized) place expression, to which the contents of the allocated register is written to at the end of the asm code.\n - An underscore (`_`) may be specified instead of an expression for ``, which will cause the contents of the register to be discarded at the end of the asm code (effectively acting as a clobber).\n - `` and `` may have different types.\n* `inlateout() ` / `inlateout() => `\n - Identical to `inout` except that the register allocator can reuse a register allocated to an `in` (this can happen if the compiler knows the `in` has the same initial value as the `inlateout`).\n - You should only write to the register after all inputs are read, otherwise you may clobber an input.\n* `const `\n - `` must be an integer or floating-point constant expression.\n - The value of the expression is formatted as a string and substituted directly into the asm template string.\n* `sym `\n - `` must refer to a `fn` or `static`.\n - A mangled symbol name referring to the item is substituted into the asm template string.\n - The substituted string does not include any modifiers (e.g. GOT, PLT, relocations, etc).\n - `` is allowed to point to a `#[thread_local]` static, in which case the asm code can combine the symbol with relocations (e.g. `@plt`, `@TPOFF`) to read from thread-local data.\n\nOperand expressions are evaluated from left to right, just like function call arguments. After the `asm!` has executed, outputs are written to in left to right order. This is significant if two outputs point to the same place: that place will contain the value of the rightmost output.\n\n## Register operands\n\nInput and output operands can be specified either as an explicit register or as a register class from which the register allocator can select a register. Explicit registers are specified as string literals (e.g. `\"eax\"`) while register classes are specified as identifiers (e.g. `reg`). Using string literals for register names enables support for architectures that use special characters in register names, such as MIPS (`$0`, `$1`, etc).\n\nNote that explicit registers treat register aliases (e.g. `r14` vs `lr` on ARM) and smaller views of a register (e.g. `eax` vs `rax`) as equivalent to the base register. It is a compile-time error to use the same explicit register for two input operands or two output operands. Additionally, it is also a compile-time error to use overlapping registers (e.g. ARM VFP) in input operands or in output operands.\n\nOnly the following types are allowed as operands for inline assembly:\n- Integers (signed and unsigned)\n- Floating-point numbers\n- Pointers (thin only)\n- Function pointers\n- SIMD vectors (structs defined with `#[repr(simd)]` and which implement `Copy`). This includes architecture-specific vector types defined in `std::arch` such as `__m128` (x86) or `int8x16_t` (ARM).\n\nHere is the list of currently supported register classes:\n\n| Architecture | Register class | Registers | LLVM constraint code |\n| ------------ | -------------- | --------- | -------------------- |\n| x86 | `reg` | `ax`, `bx`, `cx`, `dx`, `si`, `di`, `r[8-15]` (x86-64 only) | `r` |\n| x86 | `reg_abcd` | `ax`, `bx`, `cx`, `dx` | `Q` |\n| x86-32 | `reg_byte` | `al`, `bl`, `cl`, `dl`, `ah`, `bh`, `ch`, `dh` | `q` |\n| x86-64 | `reg_byte` | `al`, `bl`, `cl`, `dl`, `sil`, `dil`, `r[8-15]b`, `ah`\\*, `bh`\\*, `ch`\\*, `dh`\\* | `q` |\n| x86 | `xmm_reg` | `xmm[0-7]` (x86) `xmm[0-15]` (x86-64) | `x` |\n| x86 | `ymm_reg` | `ymm[0-7]` (x86) `ymm[0-15]` (x86-64) | `x` |\n| x86 | `zmm_reg` | `zmm[0-7]` (x86) `zmm[0-31]` (x86-64) | `v` |\n| x86 | `kreg` | `k[1-7]` | `Yk` |\n| AArch64 | `reg` | `x[0-28]`, `x30` | `r` |\n| AArch64 | `vreg` | `v[0-31]` | `w` |\n| AArch64 | `vreg_low16` | `v[0-15]` | `x` |\n| ARM | `reg` | `r[0-5]` `r7`\\*, `r[8-10]`, `r11`\\*, `r12`, `r14` | `r` |\n| ARM (Thumb) | `reg_thumb` | `r[0-r7]` | `l` |\n| ARM (ARM) | `reg_thumb` | `r[0-r10]`, `r12`, `r14` | `l` |\n| ARM | `sreg` | `s[0-31]` | `t` |\n| ARM | `sreg_low16` | `s[0-15]` | `x` |\n| ARM | `dreg` | `d[0-31]` | `w` |\n| ARM | `dreg_low16` | `d[0-15]` | `t` |\n| ARM | `dreg_low8` | `d[0-8]` | `x` |\n| ARM | `qreg` | `q[0-15]` | `w` |\n| ARM | `qreg_low8` | `q[0-7]` | `t` |\n| ARM | `qreg_low4` | `q[0-3]` | `x` |\n| NVPTX | `reg16` | None\\* | `h` |\n| NVPTX | `reg32` | None\\* | `r` |\n| NVPTX | `reg64` | None\\* | `l` |\n| RISC-V | `reg` | `x1`, `x[5-7]`, `x[9-15]`, `x[16-31]` (non-RV32E) | `r` |\n| RISC-V | `freg` | `f[0-31]` | `f` |\n| Hexagon | `reg` | `r[0-28]` | `r` |\n\n> **Note**: On x86 we treat `reg_byte` differently from `reg` because the compiler can allocate `al` and `ah` separately whereas `reg` reserves the whole register.\n>\n> Note #2: On x86-64 the high byte registers (e.g. `ah`) are only available when used as an explicit register. Specifying the `reg_byte` register class for an operand will always allocate a low byte register.\n>\n> Note #3: NVPTX doesn't have a fixed register set, so named registers are not supported.\n>\n> Note #4: On ARM the frame pointer is either `r7` or `r11` depending on the platform.\n\nAdditional register classes may be added in the future based on demand (e.g. MMX, x87, etc).\n\nEach register class has constraints on which value types they can be used with. This is necessary because the way a value is loaded into a register depends on its type. For example, on big-endian systems, loading a `i32x4` and a `i8x16` into a SIMD register may result in different register contents even if the byte-wise memory representation of both values is identical. The availability of supported types for a particular register class may depend on what target features are currently enabled.\n\n| Architecture | Register class | Target feature | Allowed types |\n| ------------ | -------------- | -------------- | ------------- |\n| x86-32 | `reg` | None | `i16`, `i32`, `f32` |\n| x86-64 | `reg` | None | `i16`, `i32`, `f32`, `i64`, `f64` |\n| x86 | `reg_byte` | None | `i8` |\n| x86 | `xmm_reg` | `sse` | `i32`, `f32`, `i64`, `f64`,

The only exception is the `freg` register class on RISC-V where `f32` values are NaN-boxed in a `f64` as required by the RISC-V architecture.\n\nWhen separate input and output expressions are specified for an `inout` operand, both expressions must have the same type. The only exception is if both operands are pointers or integers, in which case they are only required to have the same size. This restriction exists because the register allocators in LLVM and GCC sometimes cannot handle tied operands with different types.\n\n## Register names\n\nSome registers have multiple names.

The frame pointer cannot be used as an input or output. |\n| ARM | `r6` | `r6` is used internally by LLVM as a base pointer and therefore cannot be used as an input or output. |\n| x86 | `k0` | This is a constant zero register which can't be modified. |\n| x86 | `ip` | This is the program counter, not a real register. |\n| x86 | `mm[0-7]` | MMX registers are not currently supported (but may be in the future). |\n| x86 | `st([0-7])` | x87 registers are not currently supported (but may be in the future). |\n| AArch64 | `xzr` | This is a constant zero register which can't be modified. |\n| ARM | `pc` | This is the program counter, not a real register. |\n| RISC-V | `x0` | This is a constant zero register which can't be modified. |\n| RISC-V | `gp`, `tp` | These registers are reserved and cannot be used as inputs or outputs. |\n| Hexagon | `lr` | This is the link register which cannot be used as an input or output. |\n\nIn some cases LLVM will allocate a \"reserved register\" for `reg` operands even though this register cannot be explicitly specified. Assembly code making use of reserved registers should be careful since `reg` operands may alias with those registers. Reserved registers are:\n- The frame pointer on all architectures.\n- `r6` on ARM.\n\n## Template modifiers\n\nThe placeholders can be augmented by modifiers which are specified after the `:` in the curly braces. These modifiers do not affect register allocation, but change the way operands are formatted when inserted into the template string. Only one modifier is allowed per template placeholder.\n\nThe supported modifiers are a subset of LLVM's (and GCC's) [asm template argument modifiers][llvm-argmod], but do not use the same letter codes.\n\n| Architecture | Register class | Modifier | Example output | LLVM modifier |\n| ------------ | -------------- | -------- | -------------- | ------------- |\n| x86-32 | `reg` | None | `eax` | `k` |\n| x86-64 | `reg` | None | `rax` | `q` |\n| x86-32 | `reg_abcd` | `l` | `al` | `b` |\n| x86-64 | `reg` | `l` | `al` | `b` |\n| x86 | `reg_abcd` | `h` | `ah` | `h` |\n| x86 | `reg` | `x` | `ax` | `w` |\n| x86 | `reg` | `e` | `eax` | `k` |\n| x86-64 | `reg` | `r` | `rax` | `q` |\n| x86 | `reg_byte` | None | `al` / `ah` | None |\n| x86 | `xmm_reg` | None | `xmm0` | `x` |\n| x86 | `ymm_reg` | None | `ymm0` | `t` |\n| x86 | `zmm_reg` | None | `zmm0` | `g` |\n| x86 | `*mm_reg` | `x` | `xmm0` | `x` |\n| x86 | `*mm_reg` | `y` | `ymm0` | `t` |\n| x86 | `*mm_reg` | `z` | `zmm0` | `g` |\n| x86 | `kreg` | None | `k1` | None |\n| AArch64 | `reg` | None | `x0` | `x` |\n| AArch64 | `reg` | `w` | `w0` | `w` |\n| AArch64 | `reg` | `x` | `x0` | `x` |\n| AArch64 | `vreg` | None | `v0` | None |\n| AArch64 | `vreg` | `v` | `v0` | None |\n| AArch64 | `vreg` | `b` | `b0` | `b` |\n| AArch64 | `vreg` | `h` | `h0` | `h` |\n| AArch64 | `vreg` | `s` | `s0` | `s` |\n| AArch64 | `vreg` | `d` | `d0` | `d` |\n| AArch64 | `vreg` | `q` | `q0` | `q` |\n| ARM | `reg` | None | `r0` | None |\n| ARM | `sreg` | None | `s0` | None |\n| ARM | `dreg` | None | `d0` | `P` |\n| ARM | `qreg` | None | `q0` | `q` |\n| ARM | `qreg` | `e` / `f` | `d0` / `d1` | `e` / `f` |\n| NVPTX | `reg16` | None | `rs0` | None |\n| NVPTX | `reg32` | None | `r0` | None |\n| NVPTX | `reg64` | None | `rd0` | None |\n| RISC-V | `reg` | None | `x1` | None |\n| RISC-V | `freg` | None | `f0` | None |\n| Hexagon | `reg` | None | `r0` | None |\n\n> Notes:\n> - on ARM `e` / `f`: this prints the low or high doubleword register name of a NEON quad (128-bit) register.\n> - on x86: our behavior for `reg` with no modifiers differs from what GCC does. GCC will infer the modifier based on the operand value type, while we default to the full register size.\n> - on x86 `xmm_reg`: the `x`, `t` and `g` LLVM modifiers are not yet implemented in LLVM (they are supported by GCC only), but this should be a simple change.\n\nAs stated in the previous section, passing an input value smaller than the register width will result in the upper bits of the register containing undefined values. This is not a problem if the inline asm only accesses the lower bits of the register, which can be done by using a template modifier to use a subregister name in the asm code (e.g. `ax` instead of `rax`). Since this an easy pitfall, the compiler will suggest a template modifier to use where appropriate given the input type. If all references to an operand already have modifiers then the warning is suppressed for that operand.\n\n[llvm-argmod]: http://llvm.org/docs/LangRef.html#asm-template-argument-modifiers\n\n## Options\n\nFlags are used to further influence the behavior of the inline assembly block.\nCurrently the following options are defined:\n- `pure`: The `asm` block has no side effects, and its outputs depend only on its direct inputs (i.e. the values themselves, not what they point to) or values read from memory (unless the `nomem` options is also set). This allows the compiler to execute the `asm` block fewer times than specified in the program (e.g. by hoisting it out of a loop) or even eliminate it entirely if the outputs are not used.\n- `nomem`: The `asm` blocks does not read or write to any memory. This allows the compiler to cache the values of modified global variables in registers across the `asm` block since it knows that they are not read or written to by the `asm`.\n- `readonly`: The `asm` block does not write to any memory. This allows the compiler to cache the values of unmodified global variables in registers across the `asm` block since it knows that they are not written to by the `asm`.\n- `preserves_flags`: The `asm` block does not modify the flags register (defined in the rules below). This allows the compiler to avoid recomputing the condition flags after the `asm` block.\n- `noreturn`: The `asm` block never returns, and its return type is defined as `!` (never). Behavior is undefined if execution falls through past the end of the asm code. A `noreturn` asm block behaves just like a function which doesn't return; notably, local variables in scope are not dropped before it is invoked.\n- `nostack`: The `asm` block does not push data to the stack, or write to the stack red-zone (if supported by the target). If this option is *not* used then the stack pointer is guaranteed to be suitably aligned (according to the target ABI) for a function call.\n- `att_syntax`: This option is only valid on x86, and causes the assembler to use the `.att_syntax prefix` mode of the GNU assembler. Register operands are substituted in with a leading `%`.\n\nThe compiler performs some additional checks on options:\n- The `nomem` and `readonly` options are mutually exclusive: it is a compile-time error to specify both.\n- The `pure` option must be combined with either the `nomem` or `readonly` options, otherwise a compile-time error is emitted.\n- It is a compile-time error to specify `pure` on an asm block with no outputs or only discarded outputs (`_`).\n- It is a compile-time error to specify `noreturn` on an asm block with outputs.\n\n## Rules for inline assembly\n\n- Any registers not specified as inputs will contain an undefined value on entry to the asm block.\n - An \"undefined value\" in the context of inline assembly means that the register can (non-deterministically) have any one of the possible values allowed by the architecture. Notably it is not the same as an LLVM `undef` which can have a different value every time you read it (since such a concept does not exist in assembly code).\n- Any registers not specified as outputs must have the same value upon exiting the asm block as they had on entry, otherwise behavior is undefined.\n - This only applies to registers which can be specified as an input or output. Other registers follow target-specific rules.\n - Note that a `lateout` may be allocated to the same register as an `in`, in which case this rule does not apply. Code should not rely on this however since it depends on the results of register allocation.\n- Behavior is undefined if execution unwinds out of an asm block.\n - This also applies if the assembly code calls a function which then unwinds.\n- The set of memory locations that assembly code is allowed the read and write are the same as those allowed for an FFI function.\n - Refer to the unsafe code guidelines for the exact rules.\n - If the `readonly` option is set, then only memory reads are allowed.\n - If the `nomem` option is set then no reads or writes to memory are allowed.\n - These rules do not apply to memory which is private to the asm code, such as stack space allocated within the asm block.\n- The compiler cannot assume that the instructions in the asm are the ones that will actually end up executed.\n - This effectively means that the compiler must treat the `asm!` as a black box and only take the interface specification into account, not the instructions themselves.\n - Runtime code patching is allowed, via target-specific mechanisms (outside the scope of this RFC).\n- Unless the `nostack` option is set, asm code is allowed to use stack space below the stack pointer.\n - On entry to the asm block the stack pointer is guaranteed to be suitably aligned (according to the target ABI) for a function call.\n - You are responsible for making sure you don't overflow the stack (e.g. use stack probing to ensure you hit a guard page).\n - You should adjust the stack pointer when allocating stack memory as required by the target ABI.\n - The stack pointer must be restored to its original value before leaving the asm block.\n- If the `noreturn` option is set then behavior is undefined if execution falls through to the end of the asm block.\n- If the `pure` option is set then behavior is undefined if the `asm` has side-effects other than its direct outputs. Behavior is also undefined if two executions of the `asm` code with the same inputs result in different outputs.\n - When used with the `nomem` option, \"inputs\" are just the direct inputs of the `asm!`.\n - When used with the `readonly` option, \"inputs\" comprise the direct inputs of the `asm!` and any memory that the `asm!` block is allowed to read.\n- These flags registers must be restored upon exiting the asm block if the `preserves_flags` option is set:\n - x86\n - Status flags in `EFLAGS` (CF, PF, AF, ZF, SF, OF).\n - Floating-point status word (all).\n - Floating-point exception flags in `MXCSR` (PE, UE, OE, ZE, DE, IE).\n - ARM\n - Condition flags in `CPSR` (N, Z, C, V)\n - Saturation flag in `CPSR` (Q)\n - Greater than or equal flags in `CPSR` (GE).\n - Condition flags in `FPSCR` (N, Z, C, V)\n - Saturation flag in `FPSCR` (QC)\n - Floating-point exception flags in `FPSCR` (IDC, IXC, UFC, OFC, DZC, IOC).\n - AArch64\n - Condition flags (`NZCV` register).\n - Floating-point status (`FPSR` register).\n - RISC-V\n - Floating-point exception flags in `fcsr` (`fflags`).\n- On x86, the direction flag (DF in `EFLAGS`) is clear on entry to an asm block and must be clear on exit.\n - Behavior is undefined if the direction flag is set on exiting an asm block.\n- The requirement of restoring the stack pointer and non-output registers to their original value only applies when exiting an `asm!` block.\n - This means that `asm!` blocks that never return (even if not marked `noreturn`) don't need to preserve these registers.\n - When returning to a different `asm!` block than you entered (e.g. for context switching), these registers must contain the value they had upon entering the `asm!` block that you are *exiting*.\n - You cannot exit an `asm!` block that has not been entered. Neither can you exit an `asm!` block that has already been exited.\n - You are responsible for switching any target-specific state (e.g. thread-local storage, stack bounds).\n - The set of memory locations that you may access is the intersection of those allowed by the `asm!` blocks you entered and exited.\n- You cannot assume that an `asm!` block will appear exactly once in the output binary. The compiler is allowed to instantiate multiple copies of the `asm!` block, for example when the function containing it is inlined in multiple places.\n - As a consequence, you should only use [local labels] inside inline assembly code. Defining symbols in assembly code may lead to assembler and/or linker errors due to duplicate symbol definitions.\n\n> **Note**: As a general rule, the flags covered by `preserves_flags` are those which are *not* preserved when performing a function call.\n\n[local labels]: https://sourceware.org/binutils/docs/as/Symbol-Names.html#Local-Labels\n" } , LintCompletion { label : "is_sorted" ,

This is useful for very low level programming, where\nwhich register you use is important:\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# unsafe fn read_byte_in(port: u16) -> u8 {\nlet result: u8;\nllvm_asm!(\"in %dx, %al\" : \"={al}\"(result) : \"{dx}\"(port));\nresult\n# }\n```\n\n## Clobbers\n\nSome instructions modify registers which might otherwise have held\ndifferent values so we use the clobbers list to indicate to the\ncompiler not to assume any values loaded into those registers will\nstay valid.\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# fn main() { unsafe {\n// Put the value 0x200 in eax:\nllvm_asm!(\"mov $$0x200, %eax\" : /* no outputs */ : /* no inputs */ : \"eax\");\n# } }\n# #[cfg(not(any(target_arch = \"x86\", target_arch = \"x86_64\")))]\n# fn main() {}\n```\n\nInput and output registers need not be listed since that information\nis already communicated by the given constraints. Otherwise, any other\nregisters used either implicitly or explicitly should be listed.\n\nIf the assembly changes the condition code register `cc` should be\nspecified as one of the clobbers. Similarly, if the assembly modifies\nmemory, `memory` should also be specified.\n\n## Options\n\nThe last section, `options` is specific to Rust. The format is comma\nseparated literal strings (i.e. `:\"foo\", \"bar\", \"baz\"`). It's used to\nspecify some extra info about the inline assembly:\n\nCurrent valid options are:\n\n1. *volatile* - specifying this is analogous to\n `__asm__ __volatile__ (...)` in gcc/clang.\n2. *alignstack* - certain instructions expect the stack to be\n aligned a certain way (i.e. SSE) and specifying this indicates to\n the compiler to insert its usual stack alignment code\n3. *intel* - use intel syntax instead of the default AT&T.\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# fn main() {\nlet result: i32;\nunsafe {\n llvm_asm!(\"mov eax, 2\" : \"={eax}\"(result) : : : \"intel\")\n}\nprintln!(\"eax is currently {}\", result);\n# }\n# #[cfg(not(any(target_arch = \"x86\", target_arch = \"x86_64\")))]\n# fn main() {}\n```\n\n## More Information\n\nThe current implementation of the `llvm_asm!` macro is a direct binding to [LLVM's\ninline assembler expressions][llvm-docs], so be sure to check out [their\ndocumentation as well][llvm-docs] for more information about clobbers,\nconstraints, etc.\n\n[llvm-docs]: http://llvm.org/docs/LangRef.html#inline-assembler-expressions\n\nIf you need more power and don't mind losing some of the niceties of\n`llvm_asm!`, check out [global_asm](global-asm.md).\n" } ] ;

A generator is a \"resumable function\" that syntactically\nresembles a closure but compiles to much different semantics in the compiler\nitself. The primary feature of a generator is that it can be suspended during\nexecution to be resumed at a later date. Generators use the `yield` keyword to\n\"return\", and then the caller can `resume` a generator to resume execution just\nafter the `yield` keyword.\n\nGenerators are an extra-unstable feature in the compiler right now. Added in\n[RFC 2033] they're mostly intended right now as a information/constraint\ngathering phase. The intent is that experimentation can happen on the nightly\ncompiler before actual stabilization. A further RFC will be required to\nstabilize generators/coroutines and will likely contain at least a few small\ntweaks to the overall design.\n\n[RFC 2033]: https://github.com/rust-lang/rfcs/pull/2033\n\nA syntactical example of a generator is:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::{Generator, GeneratorState};\nuse std::pin::Pin;\n\nfn main() {\n let mut generator = || {\n yield 1;\n return \"foo\"\n };\n\n match Pin::new(&mut generator).resume(()) {\n GeneratorState::Yielded(1) => {}\n _ => panic!(\"unexpected value from resume\"),\n }\n match Pin::new(&mut generator).resume(()) {\n GeneratorState::Complete(\"foo\") => {}\n _ => panic!(\"unexpected value from resume\"),\n }\n}\n```\n\nGenerators are closure-like literals which can contain a `yield` statement. The\n`yield` statement takes an optional expression of a value to yield out of the\ngenerator. All generator literals implement the `Generator` trait in the\n`std::ops` module. The `Generator` trait has one main method, `resume`, which\nresumes execution of the generator at the previous suspension point.\n\nAn example of the control flow of generators is that the following example\nprints all numbers in order:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::Generator;\nuse std::pin::Pin;\n\nfn main() {\n let mut generator = || {\n println!(\"2\");\n yield;\n println!(\"4\");\n };\n\n println!(\"1\");\n Pin::new(&mut generator).resume(());\n println!(\"3\");\n Pin::new(&mut generator).resume(());\n println!(\"5\");\n}\n```\n\nAt this time the main intended use case of generators is an implementation\nprimitive for async/await syntax, but generators will likely be extended to\nergonomic implementations of iterators and other primitives in the future.\nFeedback on the design and usage is always appreciated!\n\n### The `Generator` trait\n\nThe `Generator` trait in `std::ops` currently looks like:\n\n```rust\n# #![feature(arbitrary_self_types, generator_trait)]\n# use std::ops::GeneratorState;\n# use std::pin::Pin;\n\npub trait Generator {\n type Yield;\n type Return;\n fn resume(self: Pin<&mut Self>, resume: R) -> GeneratorState;\n}\n```\n\nThe `Generator::Yield` type is the type of values that can be yielded with the\n`yield` statement. The `Generator::Return` type is the returned type of the\ngenerator. This is typically the last expression in a generator's definition or\nany value passed to `return` in a generator. The `resume` function is the entry\npoint for executing the `Generator` itself.\n\nThe return value of `resume`, `GeneratorState`, looks like:\n\n```rust\npub enum GeneratorState {\n Yielded(Y),\n Complete(R),\n}\n```\n\nThe `Yielded` variant indicates that the generator can later be resumed. This\ncorresponds to a `yield` point in a generator. The `Complete` variant indicates\nthat the generator is complete and cannot be resumed again. Calling `resume`\nafter a generator has returned `Complete` will likely result in a panic of the\nprogram.\n\n### Closure-like semantics\n\nThe closure-like syntax for generators alludes to the fact that they also have\nclosure-like semantics. Namely:\n\n* When created, a generator executes no code. A closure literal does not\n actually execute any of the closure's code on construction, and similarly a\n generator literal does not execute any code inside the generator when\n constructed.\n\n* Generators can capture outer variables by reference or by move, and this can\n be tweaked with the `move` keyword at the beginning of the closure. Like\n closures all generators will have an implicit environment which is inferred by\n the compiler. Outer variables can be moved into a generator for use as the\n generator progresses.\n\n* Generator literals produce a value with a unique type which implements the\n `std::ops::Generator` trait. This allows actual execution of the generator\n through the `Generator::resume` method as well as also naming it in return\n types and such.\n\n* Traits like `Send` and `Sync` are automatically implemented for a `Generator`\n depending on the captured variables of the environment. Unlike closures,\n generators also depend on variables live across suspension points. This means\n that although the ambient environment may be `Send` or `Sync`, the generator\n itself may not be due to internal variables live across `yield` points being\n not-`Send` or not-`Sync`. Note that generators do\n not implement traits like `Copy` or `Clone` automatically.\n\n* Whenever a generator is dropped it will drop all captured environment\n variables.\n\n### Generators as state machines\n\nIn the compiler, generators are currently compiled as state machines. Each\n`yield` expression will correspond to a different state that stores all live\nvariables over that suspension point. Resumption of a generator will dispatch on\nthe current state and then execute internally until a `yield` is reached, at\nwhich point all state is saved off in the generator and a value is returned.\n\nLet's take a look at an example to see what's going on here:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::Generator;\nuse std::pin::Pin;\n\nfn main() {\n let ret = \"foo\";\n let mut generator = move || {\n yield 1;\n return ret\n };\n\n Pin::new(&mut generator).resume(());\n Pin::new(&mut generator).resume(());\n}\n```\n\nThis generator literal will compile down to something similar to:\n\n```rust\n#![feature(arbitrary_self_types, generators, generator_trait)]\n\nuse std::ops::{Generator, GeneratorState};\nuse std::pin::Pin;\n\nfn main() {\n let ret = \"foo\";\n let mut generator = {\n enum __Generator {\n Start(&'static str),\n Yield1(&'static str),\n Done,\n }\n\n impl Generator for __Generator {\n type Yield = i32;\n type Return = &'static str;\n\n fn resume(mut self: Pin<&mut Self>, resume: ()) -> GeneratorState {\n use std::mem;\n match mem::replace(&mut *self, __Generator::Done) {\n __Generator::Start(s) => {\n *self = __Generator::Yield1(s);\n GeneratorState::Yielded(1)\n }\n\n __Generator::Yield1(s) => {\n *self = __Generator::Done;\n GeneratorState::Complete(s)\n }\n\n __Generator::Done => {\n panic!(\"generator resumed after completion\")\n }\n }\n }\n }\n\n __Generator::Start(ret)\n };\n\n Pin::new(&mut generator).resume(());\n Pin::new(&mut generator).resume(());\n}\n```\n\nNotably here we can see that the compiler is generating a fresh type,\n`__Generator` in this case. This type has a number of states (represented here\nas an `enum`) corresponding to each of the conceptual states of the generator.\nAt the beginning we're closing over our outer variable `foo` and then that\nvariable is also live over the `yield` point, so it's stored in both states.\n\nWhen the generator starts it'll immediately yield 1, but it saves off its state\njust before it does so indicating that it has reached the yield point. Upon\nresuming again we'll execute the `return ret` which returns the `Complete`\nstate.\n\nHere we can also note that the `Done` state, if resumed, panics immediately as\nit's invalid to resume a completed generator. It's also worth noting that this\nis just a rough desugaring, not a normative specification for what the compiler\ndoes.\n" } , LintCompletion { label : "marker_trait_attr" , description : "# `marker_trait_attr`\n\nThe tracking issue for this feature is: [#29864]\n\n[#29864]: https://github.com/rust-lang/rust/issues/29864\n\n------------------------\n\nNormally, Rust keeps you from adding trait implementations that could\noverlap with each other, as it would be ambiguous which to use.

In the syntax, `n` isn't necessarily a constant expression. The array is dynamically allocated on the stack and has the type of `[T]`, instead of `[T; n]`.\n\n```rust,ignore\n#![feature(unsized_locals)]\n\nfn mergesort(a: &mut [T]) {\n let mut tmp = [T; dyn a.len()];\n // ...\n}\n\nfn main() {\n let mut a = [3, 1, 5, 6];\n mergesort(&mut a);\n assert_eq!(a, [1, 3, 5, 6]);\n}\n```\n\nVLAs are not implemented yet. The syntax isn't final, either. We may need an alternative syntax for Rust 2015 because, in Rust 2015, expressions like `[e; dyn(1)]` would be ambiguous. One possible alternative proposed in the RFC is `[e; n]`: if `n` captures one or more local variables, then it is considered as `[e; dyn n]`.\n\n## Advisory on stack usage\n\nIt's advised not to casually use the `#![feature(unsized_locals)]` feature. Typical use-cases are:\n\n- When you need a by-value trait objects.\n- When you really need a fast allocation of small temporary arrays.\n\nAnother pitfall is repetitive allocation and temporaries. Currently the compiler simply extends the stack frame every time it encounters an unsized assignment. So for example, the code\n\n```rust\n#![feature(unsized_locals)]\n\nfn main() {\n let x: Box<[i32]> = Box::new([1, 2, 3, 4, 5]);\n let _x = {{{{{{{{{{*x}}}}}}}}}};\n}\n```\n\nand the code\n\n```rust\n#![feature(unsized_locals)]\n\nfn main() {\n for _ in 0..10 {\n let x: Box<[i32]> = Box::new([1, 2, 3, 4, 5]);\n let _x = *x;\n }\n}\n```\n\nwill unnecessarily extend the stack frame.\n" } , LintCompletion { label : "or_patterns" , description : "# `or_patterns`\n\nThe tracking issue for this feature is: [#54883]\n\n[#54883]: https://github.com/rust-lang/rust/issues/54883\n\n------------------------\n\nThe `or_pattern` language feature allows `|` to be arbitrarily nested within\na pattern, for example, `Some(A(0) | B(1 | 2))` becomes a valid pattern.\n\n## Examples\n\n```rust,ignore\n#![feature(or_patterns)]\n\npub enum Foo {\n Bar,\n Baz,\n Quux,\n}\n\npub fn example(maybe_foo: Option) {\n match maybe_foo {\n Some(Foo::Bar | Foo::Baz) => {\n println!(\"The value contained `Bar` or `Baz`\");\n }\n Some(_) => {\n println!(\"The value did not contain `Bar` or `Baz`\");\n }\n None => {\n println!(\"The value was `None`\");\n }\n }\n}\n```\n" } , LintCompletion { label : "member_constraints" , description : "# `member_constraints`\n\nThe tracking issue for this feature is: [#61997]\n\n[#61997]: https://github.com/rust-lang/rust/issues/61997\n\n------------------------\n\nThe `member_constraints` feature gate lets you use `impl Trait` syntax with\nmultiple unrelated lifetime parameters.\n\nA simple example is:\n\n```rust\n#![feature(member_constraints)]\n\ntrait Trait<'a, 'b> { }\nimpl Trait<'_, '_> for T {}\n\nfn foo<'a, 'b>(x: &'a u32, y: &'b u32) -> impl Trait<'a, 'b> {\n (x, y)\n}\n\nfn main() { }\n```\n\nWithout the `member_constraints` feature gate, the above example is an\nerror because both `'a` and `'b` appear in the impl Trait bounds, but\nneither outlives the other.\n" } , LintCompletion { label : "optin_builtin_traits" , description : "# `optin_builtin_traits`\n\nThe tracking issue for this feature is [#13231] \n\n[#13231]: https://github.com/rust-lang/rust/issues/13231\n\n----\n\nThe `optin_builtin_traits` feature gate allows you to define auto traits.\n\nAuto traits, like [`Send`] or [`Sync`] in the standard library, are marker traits\nthat are automatically implemented for every type, unless the type, or a type it contains, \nhas explicitly opted out via a negative impl. (Negative impls are separately controlled\nby the `negative_impls` feature.)\n\n[`Send`]: https://doc.rust-lang.org/std/marker/trait.Send.html\n[`Sync`]: https://doc.rust-lang.org/std/marker/trait.Sync.html\n\n```rust,ignore\nimpl !Trait for Type\n```\n\nExample:\n\n```rust\n#![feature(negative_impls)]\n#![feature(optin_builtin_traits)]\n\nauto trait Valid {}\n\nstruct True;\nstruct False;\n\nimpl !Valid for False {}\n\nstruct MaybeValid(T);\n\nfn must_be_valid(_t: T) { }\n\nfn main() {\n // works\n must_be_valid( MaybeValid(True) );\n \n // compiler error - trait bound not satisfied\n // must_be_valid( MaybeValid(False) );\n}\n```\n\n## Automatic trait implementations\n\nWhen a type is declared as an `auto trait`, we will automatically\ncreate impls for every struct/enum/union, unless an explicit impl is\nprovided. These automatic impls contain a where clause for each field\nof the form `T: AutoTrait`, where `T` is the type of the field and\n`AutoTrait` is the auto trait in question. As an example, consider the\nstruct `List` and the auto trait `Send`:\n\n```rust\nstruct List {\n data: T,\n next: Option>>,\n}\n```\n\nPresuming that there is no explicit impl of `Send` for `List`, the\ncompiler will supply an automatic impl of the form:\n\n```rust\nstruct List {\n data: T,\n next: Option>>,\n}\n\nunsafe impl Send for List\nwhere\n T: Send, // from the field `data`\n Option>>: Send, // from the field `next`\n{ }\n```\n\nExplicit impls may be either positive or negative. They take the form:\n\n```rust,ignore\nimpl<...> AutoTrait for StructName<..> { }\nimpl<...> !AutoTrait for StructName<..> { }\n```\n\n## Coinduction: Auto traits permit cyclic matching\n\nUnlike ordinary trait matching, auto traits are **coinductive**. This\nmeans, in short, that cycles which occur in trait matching are\nconsidered ok. As an example, consider the recursive struct `List`\nintroduced in the previous section. In attempting to determine whether\n`List: Send`, we would wind up in a cycle: to apply the impl, we must\nshow that `Option>: Send`, which will in turn require\n`Box: Send` and then finally `List: Send` again. Under ordinary\ntrait matching, this cycle would be an error, but for an auto trait it\nis considered a successful match.\n\n## Items\n\nAuto traits cannot have any trait items, such as methods or associated types. This ensures that we can generate default implementations.\n\n## Supertraits\n\nAuto traits cannot have supertraits. This is for soundness reasons, as the interaction of coinduction with implied bounds is difficult to reconcile.\n\n" } , LintCompletion { label : "rustc_attrs" , description : "# `rustc_attrs`\n\nThis feature has no tracking issue, and is therefore internal to\nthe compiler, not being intended for general use.\n\nNote: `rustc_attrs` enables many rustc-internal attributes and this page\nonly discuss a few of them.\n\n------------------------\n\nThe `rustc_attrs` feature allows debugging rustc type layouts by using\n`#[rustc_layout(...)]` to debug layout at compile time (it even works\nwith `cargo check`) as an alternative to `rustc -Z print-type-sizes`\nthat is way more verbose.\n\nOptions provided by `#[rustc_layout(...)]` are `debug`, `size`, `abi`.\nNote that it only work best with sized type without generics.\n\n## Examples\n\n```rust,ignore\n#![feature(rustc_attrs)]\n\n#[rustc_layout(abi, size)]\npub enum X {\n Y(u8, u8, u8),\n Z(isize),\n}\n```\n\nWhen that is compiled, the compiler will error with something like\n\n```text\nerror: abi: Aggregate { sized: true }\n --> src/lib.rs:4:1\n |\n4 | / pub enum T {\n5 | | Y(u8, u8, u8),\n6 | | Z(isize),\n7 | | }\n | |_^\n\nerror: size: Size { raw: 16 }\n --> src/lib.rs:4:1\n |\n4 | / pub enum T {\n5 | | Y(u8, u8, u8),\n6 | | Z(isize),\n7 | | }\n | |_^\n\nerror: aborting due to 2 previous errors\n```\n" } , LintCompletion { label : "non_ascii_idents" , description : "# `non_ascii_idents`\n\nThe tracking issue for this feature is: [#55467]\n\n[#55467]: https://github.com/rust-lang/rust/issues/55467\n\n------------------------\n\nThe `non_ascii_idents` feature adds support for non-ASCII identifiers.\n\n## Examples\n\n```rust\n#![feature(non_ascii_idents)]\n\nconst ε: f64 = 0.00001f64;\nconst Π: f64 = 3.14f64;\n```\n\n## Changes to the language reference\n\n> **Lexer:** \n> IDENTIFIER : \n>       XID_start XID_continue\\* \n>    | `_` XID_continue+ \n\nAn identifier is any nonempty Unicode string of the following form:\n\nEither\n\n * The first character has property [`XID_start`]\n * The remaining characters have property [`XID_continue`]\n\nOr\n\n * The first character is `_`\n * The identifier is more than one character, `_` alone is not an identifier\n * The remaining characters have property [`XID_continue`]\n\nthat does _not_ occur in the set of [strict keywords].\n\n> **Note**: [`XID_start`] and [`XID_continue`] as character properties cover the\n> character ranges used to form the more familiar C and Java language-family\n> identifiers.\n\n[`XID_start`]: http://unicode.org/cldr/utility/list-unicodeset.jsp?a=%5B%3AXID_Start%3A%5D&abb=on&g=&i=\n[`XID_continue`]: http://unicode.org/cldr/utility/list-unicodeset.jsp?a=%5B%3AXID_Continue%3A%5D&abb=on&g=&i=\n[strict keywords]: ../../reference/keywords.md#strict-keywords\n" } , LintCompletion { label : "box_syntax" , description : "# `box_syntax`\n\nThe tracking issue for this feature is: [#49733]\n\n[#49733]: https://github.com/rust-lang/rust/issues/49733\n\nSee also [`box_patterns`](box-patterns.md)\n\n------------------------\n\nCurrently the only stable way to create a `Box` is via the `Box::new` method.\nAlso it is not possible in stable Rust to destructure a `Box` in a match\npattern.

The marker is the attribute `#[lang = \"...\"]` and there are\nvarious different values of `...`, i.e. various different 'lang\nitems'.\n\nFor example, `Box` pointers require two lang items, one for allocation\nand one for deallocation. A freestanding program that uses the `Box`\nsugar for dynamic allocations via `malloc` and `free`:\n\n```rust,ignore\n#![feature(lang_items, box_syntax, start, libc, core_intrinsics)]\n#![no_std]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\nextern crate libc;\n\n#[lang = \"owned_box\"]\npub struct Box(*mut T);\n\n#[lang = \"exchange_malloc\"]\nunsafe fn allocate(size: usize, _align: usize) -> *mut u8 {\n let p = libc::malloc(size as libc::size_t) as *mut u8;\n\n // Check if `malloc` failed:\n if p as usize == 0 {\n intrinsics::abort();\n }\n\n p\n}\n\n#[lang = \"box_free\"]\nunsafe fn box_free(ptr: *mut T) {\n libc::free(ptr as *mut libc::c_void)\n}\n\n#[start]\nfn main(_argc: isize, _argv: *const *const u8) -> isize {\n let _x = box 1;\n\n 0\n}\n\n#[lang = \"eh_personality\"] extern fn rust_eh_personality() {}\n#[lang = \"panic_impl\"] extern fn rust_begin_panic(info: &PanicInfo) -> ! { unsafe { intrinsics::abort() } }\n#[no_mangle] pub extern fn rust_eh_register_frames () {}\n#[no_mangle] pub extern fn rust_eh_unregister_frames () {}\n```\n\nNote the use of `abort`: the `exchange_malloc` lang item is assumed to\nreturn a valid pointer, and so needs to do the check internally.\n\nOther features provided by lang items include:\n\n- overloadable operators via traits: the traits corresponding to the\n `==`, `<`, dereferencing (`*`) and `+` (etc.) operators are all\n marked with lang items; those specific four are `eq`, `ord`,\n `deref`, and `add` respectively.\n- stack unwinding and general failure; the `eh_personality`,\n `panic` and `panic_bounds_checks` lang items.\n- the traits in `std::marker` used to indicate types of\n various kinds; lang items `send`, `sync` and `copy`.\n- the marker types and variance indicators found in\n `std::marker`; lang items `covariant_type`,\n `contravariant_lifetime`, etc.\n\nLang items are loaded lazily by the compiler; e.g. if one never uses\n`Box` then there is no need to define functions for `exchange_malloc`\nand `box_free`. `rustc` will emit an error when an item is needed\nbut not found in the current crate or any that it depends on.\n\nMost lang items are defined by `libcore`, but if you're trying to build\nan executable without the standard library, you'll run into the need\nfor lang items. The rest of this page focuses on this use-case, even though\nlang items are a bit broader than that.\n\n### Using libc\n\nIn order to build a `#[no_std]` executable we will need libc as a dependency.\nWe can specify this using our `Cargo.toml` file:\n\n```toml\n[dependencies]\nlibc = { version = \"0.2.14\", default-features = false }\n```\n\nNote that the default features have been disabled. This is a critical step -\n**the default features of libc include the standard library and so must be\ndisabled.**\n\n### Writing an executable without stdlib\n\nControlling the entry point is possible in two ways: the `#[start]` attribute,\nor overriding the default shim for the C `main` function with your own.\n\nThe function marked `#[start]` is passed the command line parameters\nin the same format as C:\n\n```rust,ignore\n#![feature(lang_items, core_intrinsics)]\n#![feature(start)]\n#![no_std]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\n// Pull in the system libc library for what crt0.o likely requires.\nextern crate libc;\n\n// Entry point for this program.\n#[start]\nfn start(_argc: isize, _argv: *const *const u8) -> isize {\n 0\n}\n\n// These functions are used by the compiler, but not\n// for a bare-bones hello world. These are normally\n// provided by libstd.\n#[lang = \"eh_personality\"]\n#[no_mangle]\npub extern fn rust_eh_personality() {\n}\n\n#[lang = \"panic_impl\"]\n#[no_mangle]\npub extern fn rust_begin_panic(info: &PanicInfo) -> ! {\n unsafe { intrinsics::abort() }\n}\n```\n\nTo override the compiler-inserted `main` shim, one has to disable it\nwith `#![no_main]` and then create the appropriate symbol with the\ncorrect ABI and the correct name, which requires overriding the\ncompiler's name mangling too:\n\n```rust,ignore\n#![feature(lang_items, core_intrinsics)]\n#![feature(start)]\n#![no_std]\n#![no_main]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\n// Pull in the system libc library for what crt0.o likely requires.\nextern crate libc;\n\n// Entry point for this program.\n#[no_mangle] // ensure that this symbol is called `main` in the output\npub extern fn main(_argc: i32, _argv: *const *const u8) -> i32 {\n 0\n}\n\n// These functions are used by the compiler, but not\n// for a bare-bones hello world. These are normally\n// provided by libstd.\n#[lang = \"eh_personality\"]\n#[no_mangle]\npub extern fn rust_eh_personality() {\n}\n\n#[lang = \"panic_impl\"]\n#[no_mangle]\npub extern fn rust_begin_panic(info: &PanicInfo) -> ! {\n unsafe { intrinsics::abort() }\n}\n```\n\nIn many cases, you may need to manually link to the `compiler_builtins` crate\nwhen building a `no_std` binary. You may observe this via linker error messages\nsuch as \"```undefined reference to `__rust_probestack'```\".\n\n## More about the language items\n\nThe compiler currently makes a few assumptions about symbols which are\navailable in the executable to call. Normally these functions are provided by\nthe standard library, but without it you must define your own. These symbols\nare called \"language items\", and they each have an internal name, and then a\nsignature that an implementation must conform to.\n\nThe first of these functions, `rust_eh_personality`, is used by the failure\nmechanisms of the compiler. This is often mapped to GCC's personality function\n(see the [libstd implementation][unwind] for more information), but crates\nwhich do not trigger a panic can be assured that this function is never\ncalled.

Negative impls are a commitment not to implement the given trait for the named types.\n\n## Orphan and overlap rules\n\nNegative impls must obey the same orphan rules as a positive impl. This implies you cannot add a negative impl for types defined in upstream crates and so forth.\n\nSimilarly, negative impls cannot overlap with positive impls, again using the same \"overlap\" check that we ordinarily use to determine if two impls overlap. (Note that positive impls typically cannot overlap with one another either, except as permitted by specialization.)\n\n## Interaction with auto traits\n\nDeclaring a negative impl `impl !SomeAutoTrait for SomeType` for an\nauto-trait serves two purposes:\n\n* as with any trait, it declares that `SomeType` will never implement `SomeAutoTrait`;\n* it disables the automatic `SomeType: SomeAutoTrait` impl that would otherwise have been generated.\n\nNote that, at present, there is no way to indicate that a given type\ndoes not implement an auto trait *but that it may do so in the\nfuture*. For ordinary types, this is done by simply not declaring any\nimpl at all, but that is not an option for auto traits. A workaround\nis that one could embed a marker type as one of the fields, where the\nmarker type is `!AutoTrait`.\n\n## Immediate uses\n\nNegative impls are used to declare that `&T: !DerefMut` and `&mut T: !Clone`, as required to fix the soundness of `Pin` described in [#66544](https://github.com/rust-lang/rust/issues/66544).\n\nThis serves two purposes:\n\n* For proving the correctness of unsafe code, we can use that impl as evidence that no `DerefMut` or `Clone` impl exists.\n* It prevents downstream crates from creating such impls.\n" } , LintCompletion { label : "abi_ptx" , description : "# `abi_ptx`\n\nThe tracking issue for this feature is: [#38788]\n\n[#38788]: https://github.com/rust-lang/rust/issues/38788\n\n------------------------\n\nWhen emitting PTX code, all vanilla Rust functions (`fn`) get translated to\n\"device\" functions.

This is\ngenerally unwanted unless you are building another plugin.\n\nThe usual practice is to put compiler plugins in their own crate, separate from\nany `macro_rules!` macros or ordinary Rust code meant to be used by consumers\nof a library.\n\n# Lint plugins\n\nPlugins can extend [Rust's lint\ninfrastructure](../../reference/attributes/diagnostics.md#lint-check-attributes) with\nadditional checks for code style, safety, etc. Now let's write a plugin\n[`lint-plugin-test.rs`](https://github.com/rust-lang/rust/blob/master/src/test/ui-fulldeps/auxiliary/lint-plugin-test.rs)\nthat warns about any item named `lintme`.\n\n```rust,ignore\n#![feature(plugin_registrar)]\n#![feature(box_syntax, rustc_private)]\n\nextern crate rustc_ast;\n\n// Load rustc as a plugin to get macros\nextern crate rustc_driver;\n#[macro_use]\nextern crate rustc_lint;\n#[macro_use]\nextern crate rustc_session;\n\nuse rustc_driver::plugin::Registry;\nuse rustc_lint::{EarlyContext, EarlyLintPass, LintArray, LintContext, LintPass};\nuse rustc_ast::ast;\ndeclare_lint!(TEST_LINT, Warn, \"Warn about items named 'lintme'\");\n\ndeclare_lint_pass!(Pass => [TEST_LINT]);\n\nimpl EarlyLintPass for Pass {\n fn check_item(&mut self, cx: &EarlyContext, it: &ast::Item) {\n if it.ident.name.as_str() == \"lintme\" {\n cx.lint(TEST_LINT, |lint| {\n lint.build(\"item is named 'lintme'\").set_span(it.span).emit()\n });\n }\n }\n}\n\n#[plugin_registrar]\npub fn plugin_registrar(reg: &mut Registry) {\n reg.lint_store.register_lints(&[&TEST_LINT]);\n reg.lint_store.register_early_pass(|| box Pass);\n}\n```\n\nThen code like\n\n```rust,ignore\n#![feature(plugin)]\n#![plugin(lint_plugin_test)]\n\nfn lintme() { }\n```\n\nwill produce a compiler warning:\n\n```txt\nfoo.rs:4:1: 4:16 warning: item is named 'lintme', #[warn(test_lint)] on by default\nfoo.rs:4 fn lintme() { }\n ^~~~~~~~~~~~~~~\n```\n\nThe components of a lint plugin are:\n\n* one or more `declare_lint!` invocations, which define static `Lint` structs;\n\n* a struct holding any state needed by the lint pass (here, none);\n\n* a `LintPass`\n implementation defining how to check each syntax element. A single\n `LintPass` may call `span_lint` for several different `Lint`s, but should\n register them all through the `get_lints` method.\n\nLint passes are syntax traversals, but they run at a late stage of compilation\nwhere type information is available. `rustc`'s [built-in\nlints](https://github.com/rust-lang/rust/blob/master/src/librustc_session/lint/builtin.rs)\nmostly use the same infrastructure as lint plugins, and provide examples of how\nto access type information.\n\nLints defined by plugins are controlled by the usual [attributes and compiler\nflags](../../reference/attributes/diagnostics.md#lint-check-attributes), e.g.\n`#[allow(test_lint)]` or `-A test-lint`. These identifiers are derived from the\nfirst argument to `declare_lint!`, with appropriate case and punctuation\nconversion.\n\nYou can run `rustc -W help foo.rs` to see a list of lints known to `rustc`,\nincluding those provided by plugins loaded by `foo.rs`.\n" } , LintCompletion { label : "concat_idents" , description : "# `concat_idents`\n\nThe tracking issue for this feature is: [#29599]\n\n[#29599]: https://github.com/rust-lang/rust/issues/29599\n\n------------------------\n\nThe `concat_idents` feature adds a macro for concatenating multiple identifiers\ninto one identifier.\n\n## Examples\n\n```rust\n#![feature(concat_idents)]\n\nfn main() {\n fn foobar() -> u32 { 23 }\n let f = concat_idents!(foo, bar);\n assert_eq!(f(), 23);\n}\n```" } , LintCompletion { label : "update_panic_count" , description : "# `update_panic_count`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "fn_traits" , description : "# `fn_traits`\n\nThe tracking issue for this feature is [#29625]\n\nSee Also: [`unboxed_closures`](../language-features/unboxed-closures.md)\n\n[#29625]: https://github.com/rust-lang/rust/issues/29625\n\n----\n\nThe `fn_traits` feature allows for implementation of the [`Fn*`] traits\nfor creating custom closure-like types.\n\n[`Fn*`]: https://doc.rust-lang.org/std/ops/trait.Fn.html\n\n```rust\n#![feature(unboxed_closures)]\n#![feature(fn_traits)]\n\nstruct Adder {\n a: u32\n}\n\nimpl FnOnce<(u32, )> for Adder {\n type Output = u32;\n extern \"rust-call\" fn call_once(self, b: (u32, )) -> Self::Output {\n self.a + b.0\n }\n}\n\nfn main() {\n let adder = Adder { a: 3 };\n assert_eq!(adder(2), 5);\n}\n```\n" } , LintCompletion { label : "try_trait" , description : "# `try_trait`\n\nThe tracking issue for this feature is: [#42327]\n\n[#42327]: https://github.com/rust-lang/rust/issues/42327\n\n------------------------\n\nThis introduces a new trait `Try` for extending the `?` operator to types\nother than `Result` (a part of [RFC 1859]).

The macro is a no-frills\ninterface to LLVM's concept of [module-level inline assembly]. That is,\nall caveats applicable to LLVM's module-level inline assembly apply\nto `global_asm!`.\n\n[module-level inline assembly]: http://llvm.org/docs/LangRef.html#module-level-inline-assembly\n\n`global_asm!` fills a role not currently satisfied by either `asm!`\nor `#[naked]` functions. The programmer has _all_ features of the\nassembler at their disposal. The linker will expect to resolve any\nsymbols defined in the inline assembly, modulo any symbols marked as\nexternal. It also means syntax for directives and assembly follow the\nconventions of the assembler in your toolchain.\n\nA simple usage looks like this:\n\n```rust,ignore\n# #![feature(global_asm)]\n# you also need relevant target_arch cfgs\nglobal_asm!(include_str!(\"something_neato.s\"));\n```\n\nAnd a more complicated usage looks like this:\n\n```rust,ignore\n# #![feature(global_asm)]\n# #![cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n\npub mod sally {\n global_asm!(r#\"\n .global foo\n foo:\n jmp baz\n \"#);\n\n #[no_mangle]\n pub unsafe extern \"C\" fn baz() {}\n}\n\n// the symbols `foo` and `bar` are global, no matter where\n// `global_asm!` was used.\nextern \"C\" {\n fn foo();\n fn bar();\n}\n\npub mod harry {\n global_asm!(r#\"\n .global bar\n bar:\n jmp quux\n \"#);\n\n #[no_mangle]\n pub unsafe extern \"C\" fn quux() {}\n}\n```\n\nYou may use `global_asm!` multiple times, anywhere in your crate, in\nwhatever way suits you. The effect is as if you concatenated all\nusages and placed the larger, single usage in the crate root.\n\n------------------------\n\nIf you don't need quite as much power and flexibility as\n`global_asm!` provides, and you don't mind restricting your inline\nassembly to `fn` bodies only, you might try the\n[asm](asm.md) feature instead.\n" } , LintCompletion { label : "sort_internals" , description : "# `sort_internals`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "test" , description : "# `test`\n\nThe tracking issue for this feature is: None.\n\n------------------------\n\nThe internals of the `test` crate are unstable, behind the `test` flag. The\nmost widely used part of the `test` crate are benchmark tests, which can test\nthe performance of your code. Let's make our `src/lib.rs` look like this\n(comments elided):\n\n```rust,ignore\n#![feature(test)]\n\nextern crate test;\n\npub fn add_two(a: i32) -> i32 {\n a + 2\n}\n\n#[cfg(test)]\nmod tests {\n use super::*;\n use test::Bencher;\n\n #[test]\n fn it_works() {\n assert_eq!(4, add_two(2));\n }\n\n #[bench]\n fn bench_add_two(b: &mut Bencher) {\n b.iter(|| add_two(2));\n }\n}\n```\n\nNote the `test` feature gate, which enables this unstable feature.\n\nWe've imported the `test` crate, which contains our benchmarking support.\nWe have a new function as well, with the `bench` attribute. Unlike regular\ntests, which take no arguments, benchmark tests take a `&mut Bencher`. This\n`Bencher` provides an `iter` method, which takes a closure. This closure\ncontains the code we'd like to benchmark.\n\nWe can run benchmark tests with `cargo bench`:\n\n```bash\n$ cargo bench\n Compiling adder v0.0.1 (file:///home/steve/tmp/adder)\n Running target/release/adder-91b3e234d4ed382a\n\nrunning 2 tests\ntest tests::it_works ... ignored\ntest tests::bench_add_two ... bench: 1 ns/iter (+/- 0)\n\ntest result: ok. 0 passed; 0 failed; 1 ignored; 1 measured\n```\n\nOur non-benchmark test was ignored. You may have noticed that `cargo bench`\ntakes a bit longer than `cargo test`. This is because Rust runs our benchmark\na number of times, and then takes the average. Because we're doing so little\nwork in this example, we have a `1 ns/iter (+/- 0)`, but this would show\nthe variance if there was one.\n\nAdvice on writing benchmarks:\n\n\n* Move setup code outside the `iter` loop; only put the part you want to measure inside\n* Make the code do \"the same thing\" on each iteration; do not accumulate or change state\n* Make the outer function idempotent too; the benchmark runner is likely to run\n it many times\n* Make the inner `iter` loop short and fast so benchmark runs are fast and the\n calibrator can adjust the run-length at fine resolution\n* Make the code in the `iter` loop do something simple, to assist in pinpointing\n performance improvements (or regressions)\n\n## Gotcha: optimizations\n\nThere's another tricky part to writing benchmarks: benchmarks compiled with\noptimizations activated can be dramatically changed by the optimizer so that\nthe benchmark is no longer benchmarking what one expects. For example, the\ncompiler might recognize that some calculation has no external effects and\nremove it entirely.\n\n```rust,ignore\n#![feature(test)]\n\nextern crate test;\nuse test::Bencher;\n\n#[bench]\nfn bench_xor_1000_ints(b: &mut Bencher) {\n b.iter(|| {\n (0..1000).fold(0, |old, new| old ^ new);\n });\n}\n```\n\ngives the following results\n\n```text\nrunning 1 test\ntest bench_xor_1000_ints ... bench: 0 ns/iter (+/- 0)\n\ntest result: ok. 0 passed; 0 failed; 0 ignored; 1 measured\n```\n\nThe benchmarking runner offers two ways to avoid this. Either, the closure that\nthe `iter` method receives can return an arbitrary value which forces the\noptimizer to consider the result used and ensures it cannot remove the\ncomputation entirely. This could be done for the example above by adjusting the\n`b.iter` call to\n\n```rust\n# struct X;\n# impl X { fn iter(&self, _: F) where F: FnMut() -> T {} } let b = X;\nb.iter(|| {\n // Note lack of `;` (could also use an explicit `return`).\n (0..1000).fold(0, |old, new| old ^ new)\n});\n```\n\nOr, the other option is to call the generic `test::black_box` function, which\nis an opaque \"black box\" to the optimizer and so forces it to consider any\nargument as used.\n\n```rust\n#![feature(test)]\n\nextern crate test;\n\n# fn main() {\n# struct X;\n# impl X { fn iter(&self, _: F) where F: FnMut() -> T {} } let b = X;\nb.iter(|| {\n let n = test::black_box(1000);\n\n (0..n).fold(0, |a, b| a ^ b)\n})\n# }\n```\n\nNeither of these read or modify the value, and are very cheap for small values.\nLarger values can be passed indirectly to reduce overhead (e.g.\n`black_box(&huge_struct)`).\n\nPerforming either of the above changes gives the following benchmarking results\n\n```text\nrunning 1 test\ntest bench_xor_1000_ints ... bench: 131 ns/iter (+/- 3)\n\ntest result: ok. 0 passed; 0 failed; 0 ignored; 1 measured\n```\n\nHowever, the optimizer can still modify a testcase in an undesirable manner\neven when using either of the above.\n" } , LintCompletion { label : "windows_stdio" , description : "# `windows_stdio`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "allocator_api" , description : "# `allocator_api`\n\nThe tracking issue for this feature is [#32838]\n\n[#32838]: https://github.com/rust-lang/rust/issues/32838\n\n------------------------\n\nSometimes you want the memory for one collection to use a different\nallocator than the memory for another collection.

Rust supports using inline\nassembly to do this via the `asm!` macro.\n\n# Guide-level explanation\n[guide-level-explanation]: #guide-level-explanation\n\nRust provides support for inline assembly via the `asm!` macro.\nIt can be used to embed handwritten assembly in the assembly output generated by the compiler.\nGenerally this should not be necessary, but might be where the required performance or timing\ncannot be otherwise achieved. Accessing low level hardware primitives, e.g. in kernel code, may also demand this functionality.\n\n> **Note**: the examples here are given in x86/x86-64 assembly, but other architectures are also supported.\n\nInline assembly is currently supported on the following architectures:\n- x86 and x86-64\n- ARM\n- AArch64\n- RISC-V\n- NVPTX\n- Hexagon\n\n## Basic usage\n\nLet us start with the simplest possible example:\n\n```rust,allow_fail\n# #![feature(asm)]\nunsafe {\n asm!(\"nop\");\n}\n```\n\nThis will insert a NOP (no operation) instruction into the assembly generated by the compiler.\nNote that all `asm!` invocations have to be inside an `unsafe` block, as they could insert\narbitrary instructions and break various invariants. The instructions to be inserted are listed\nin the first argument of the `asm!` macro as a string literal.\n\n## Inputs and outputs\n\nNow inserting an instruction that does nothing is rather boring. Let us do something that\nactually acts on data:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet x: u64;\nunsafe {\n asm!(\"mov {}, 5\", out(reg) x);\n}\nassert_eq!(x, 5);\n```\n\nThis will write the value `5` into the `u64` variable `x`.\nYou can see that the string literal we use to specify instructions is actually a template string.\nIt is governed by the same rules as Rust [format strings][format-syntax].\nThe arguments that are inserted into the template however look a bit different then you may\nbe familiar with. First we need to specify if the variable is an input or an output of the\ninline assembly. In this case it is an output. We declared this by writing `out`.\nWe also need to specify in what kind of register the assembly expects the variable.\nIn this case we put it in an arbitrary general purpose register by specifying `reg`.\nThe compiler will choose an appropriate register to insert into\nthe template and will read the variable from there after the inline assembly finishes executing.\n\nLet us see another example that also uses an input:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet i: u64 = 3;\nlet o: u64;\nunsafe {\n asm!(\n \"mov {0}, {1}\",\n \"add {0}, {number}\",\n out(reg) o,\n in(reg) i,\n number = const 5,\n );\n}\nassert_eq!(o, 8);\n```\n\nThis will add `5` to the input in variable `i` and write the result to variable `o`.\nThe particular way this assembly does this is first copying the value from `i` to the output,\nand then adding `5` to it.\n\nThe example shows a few things:\n\nFirst, we can see that `asm!` allows multiple template string arguments; each\none is treated as a separate line of assembly code, as if they were all joined\ntogether with newlines between them. This makes it easy to format assembly\ncode.\n\nSecond, we can see that inputs are declared by writing `in` instead of `out`.\n\nThird, one of our operands has a type we haven't seen yet, `const`.\nThis tells the compiler to expand this argument to value directly inside the assembly template.\nThis is only possible for constants and literals.\n\nFourth, we can see that we can specify an argument number, or name as in any format string.\nFor inline assembly templates this is particularly useful as arguments are often used more than once.\nFor more complex inline assembly using this facility is generally recommended, as it improves\nreadability, and allows reordering instructions without changing the argument order.\n\nWe can further refine the above example to avoid the `mov` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut x: u64 = 3;\nunsafe {\n asm!(\"add {0}, {number}\", inout(reg) x, number = const 5);\n}\nassert_eq!(x, 8);\n```\n\nWe can see that `inout` is used to specify an argument that is both input and output.\nThis is different from specifying an input and output separately in that it is guaranteed to assign both to the same register.\n\nIt is also possible to specify different variables for the input and output parts of an `inout` operand:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet x: u64 = 3;\nlet y: u64;\nunsafe {\n asm!(\"add {0}, {number}\", inout(reg) x => y, number = const 5);\n}\nassert_eq!(y, 8);\n```\n\n## Late output operands\n\nThe Rust compiler is conservative with its allocation of operands. It is assumed that an `out`\ncan be written at any time, and can therefore not share its location with any other argument.\nHowever, to guarantee optimal performance it is important to use as few registers as possible,\nso they won't have to be saved and reloaded around the inline assembly block.\nTo achieve this Rust provides a `lateout` specifier. This can be used on any output that is\nwritten only after all inputs have been consumed.\nThere is also a `inlateout` variant of this specifier.\n\nHere is an example where `inlateout` *cannot* be used:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nlet c: u64 = 4;\nunsafe {\n asm!(\n \"add {0}, {1}\",\n \"add {0}, {2}\",\n inout(reg) a,\n in(reg) b,\n in(reg) c,\n );\n}\nassert_eq!(a, 12);\n```\n\nHere the compiler is free to allocate the same register for inputs `b` and `c` since it knows they have the same value. However it must allocate a separate register for `a` since it uses `inout` and not `inlateout`. If `inlateout` was used, then `a` and `c` could be allocated to the same register, in which case the first instruction to overwrite the value of `c` and cause the assembly code to produce the wrong result.\n\nHowever the following example can use `inlateout` since the output is only modified after all input registers have been read:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nunsafe {\n asm!(\"add {0}, {1}\", inlateout(reg) a, in(reg) b);\n}\nassert_eq!(a, 8);\n```\n\nAs you can see, this assembly fragment will still work correctly if `a` and `b` are assigned to the same register.\n\n## Explicit register operands\n\nSome instructions require that the operands be in a specific register.\nTherefore, Rust inline assembly provides some more specific constraint specifiers.\nWhile `reg` is generally available on any architecture, these are highly architecture specific. E.g. for x86 the general purpose registers `eax`, `ebx`, `ecx`, `edx`, `ebp`, `esi`, and `edi`\namong others can be addressed by their name.\n\n```rust,allow_fail,no_run\n# #![feature(asm)]\nlet cmd = 0xd1;\nunsafe {\n asm!(\"out 0x64, eax\", in(\"eax\") cmd);\n}\n```\n\nIn this example we call the `out` instruction to output the content of the `cmd` variable\nto port `0x64`. Since the `out` instruction only accepts `eax` (and its sub registers) as operand\nwe had to use the `eax` constraint specifier.\n\nNote that unlike other operand types, explicit register operands cannot be used in the template string: you can't use `{}` and should write the register name directly instead. Also, they must appear at the end of the operand list after all other operand types.\n\nConsider this example which uses the x86 `mul` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nfn mul(a: u64, b: u64) -> u128 {\n let lo: u64;\n let hi: u64;\n\n unsafe {\n asm!(\n // The x86 mul instruction takes rax as an implicit input and writes\n // the 128-bit result of the multiplication to rax:rdx.\n \"mul {}\",\n in(reg) a,\n inlateout(\"rax\") b => lo,\n lateout(\"rdx\") hi\n );\n }\n\n ((hi as u128) << 64) + lo as u128\n}\n```\n\nThis uses the `mul` instruction to multiply two 64-bit inputs with a 128-bit result.\nThe only explicit operand is a register, that we fill from the variable `a`.\nThe second operand is implicit, and must be the `rax` register, which we fill from the variable `b`.\nThe lower 64 bits of the result are stored in `rax` from which we fill the variable `lo`.\nThe higher 64 bits are stored in `rdx` from which we fill the variable `hi`.\n\n## Clobbered registers\n\nIn many cases inline assembly will modify state that is not needed as an output.\nUsually this is either because we have to use a scratch register in the assembly,\nor instructions modify state that we don't need to further examine.\nThis state is generally referred to as being \"clobbered\".\nWe need to tell the compiler about this since it may need to save and restore this state\naround the inline assembly block.\n\n```rust,allow_fail\n# #![feature(asm)]\nlet ebx: u32;\nlet ecx: u32;\n\nunsafe {\n asm!(\n \"cpuid\",\n // EAX 4 selects the \"Deterministic Cache Parameters\" CPUID leaf\n inout(\"eax\") 4 => _,\n // ECX 0 selects the L0 cache information.\n inout(\"ecx\") 0 => ecx,\n lateout(\"ebx\") ebx,\n lateout(\"edx\") _,\n );\n}\n\nprintln!(\n \"L1 Cache: {}\",\n ((ebx >> 22) + 1) * (((ebx >> 12) & 0x3ff) + 1) * ((ebx & 0xfff) + 1) * (ecx + 1)\n);\n```\n\nIn the example above we use the `cpuid` instruction to get the L1 cache size.\nThis instruction writes to `eax`, `ebx`, `ecx`, and `edx`, but for the cache size we only care about the contents of `ebx` and `ecx`.\n\nHowever we still need to tell the compiler that `eax` and `edx` have been modified so that it can save any values that were in these registers before the asm. This is done by declaring these as outputs but with `_` instead of a variable name, which indicates that the output value is to be discarded.\n\nThis can also be used with a general register class (e.g. `reg`) to obtain a scratch register for use inside the asm code:\n\n```rust,allow_fail\n# #![feature(asm)]\n// Multiply x by 6 using shifts and adds\nlet mut x: u64 = 4;\nunsafe {\n asm!(\n \"mov {tmp}, {x}\",\n \"shl {tmp}, 1\",\n \"shl {x}, 2\",\n \"add {x}, {tmp}\",\n x = inout(reg) x,\n tmp = out(reg) _,\n );\n}\nassert_eq!(x, 4 * 6);\n```\n\n## Symbol operands\n\nA special operand type, `sym`, allows you to use the symbol name of a `fn` or `static` in inline assembly code.\nThis allows you to call a function or access a global variable without needing to keep its address in a register.\n\n```rust,allow_fail\n# #![feature(asm)]\nextern \"C\" fn foo(arg: i32) {\n println!(\"arg = {}\", arg);\n}\n\nfn call_foo(arg: i32) {\n unsafe {\n asm!(\n \"call {}\",\n sym foo,\n // 1st argument in rdi, which is caller-saved\n inout(\"rdi\") arg => _,\n // All caller-saved registers must be marked as clobberred\n out(\"rax\") _, out(\"rcx\") _, out(\"rdx\") _, out(\"rsi\") _,\n out(\"r8\") _, out(\"r9\") _, out(\"r10\") _, out(\"r11\") _,\n out(\"xmm0\") _, out(\"xmm1\") _, out(\"xmm2\") _, out(\"xmm3\") _,\n out(\"xmm4\") _, out(\"xmm5\") _, out(\"xmm6\") _, out(\"xmm7\") _,\n out(\"xmm8\") _, out(\"xmm9\") _, out(\"xmm10\") _, out(\"xmm11\") _,\n out(\"xmm12\") _, out(\"xmm13\") _, out(\"xmm14\") _, out(\"xmm15\") _,\n )\n }\n}\n```\n\nNote that the `fn` or `static` item does not need to be public or `#[no_mangle]`:\nthe compiler will automatically insert the appropriate mangled symbol name into the assembly code.\n\n## Register template modifiers\n\nIn some cases, fine control is needed over the way a register name is formatted when inserted into the template string. This is needed when an architecture's assembly language has several names for the same register, each typically being a \"view\" over a subset of the register (e.g. the low 32 bits of a 64-bit register).\n\nBy default the compiler will always choose the name that refers to the full register size (e.g. `rax` on x86-64, `eax` on x86, etc).\n\nThis default can be overriden by using modifiers on the template string operands, just like you would with format strings:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut x: u16 = 0xab;\n\nunsafe {\n asm!(\"mov {0:h}, {0:l}\", inout(reg_abcd) x);\n}\n\nassert_eq!(x, 0xabab);\n```\n\nIn this example, we use the `reg_abcd` register class to restrict the register allocator to the 4 legacy x86 register (`ax`, `bx`, `cx`, `dx`) of which the first two bytes can be addressed independently.\n\nLet us assume that the register allocator has chosen to allocate `x` in the `ax` register.\nThe `h` modifier will emit the register name for the high byte of that register and the `l` modifier will emit the register name for the low byte. The asm code will therefore be expanded as `mov ah, al` which copies the low byte of the value into the high byte.\n\nIf you use a smaller data type (e.g. `u16`) with an operand and forget the use template modifiers, the compiler will emit a warning and suggest the correct modifier to use.\n\n## Options\n\nBy default, an inline assembly block is treated the same way as an external FFI function call with a custom calling convention: it may read/write memory, have observable side effects, etc. However in many cases, it is desirable to give the compiler more information about what the assembly code is actually doing so that it can optimize better.\n\nLet's take our previous example of an `add` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nunsafe {\n asm!(\n \"add {0}, {1}\",\n inlateout(reg) a, in(reg) b,\n options(pure, nomem, nostack),\n );\n}\nassert_eq!(a, 8);\n```\n\nOptions can be provided as an optional final argument to the `asm!` macro. We specified three options here:\n- `pure` means that the asm code has no observable side effects and that its output depends only on its inputs. This allows the compiler optimizer to call the inline asm fewer times or even eliminate it entirely.\n- `nomem` means that the asm code does not read or write to memory. By default the compiler will assume that inline assembly can read or write any memory address that is accessible to it (e.g. through a pointer passed as an operand, or a global).\n- `nostack` means that the asm code does not push any data onto the stack. This allows the compiler to use optimizations such as the stack red zone on x86-64 to avoid stack pointer adjustments.\n\nThese allow the compiler to better optimize code using `asm!`, for example by eliminating pure `asm!` blocks whose outputs are not needed.\n\nSee the reference for the full list of available options and their effects.\n\n# Reference-level explanation\n[reference-level-explanation]: #reference-level-explanation\n\nInline assembler is implemented as an unsafe macro `asm!()`.\nThe first argument to this macro is a template string literal used to build the final assembly.\nThe following arguments specify input and output operands.\nWhen required, options are specified as the final argument.\n\nThe following ABNF specifies the general syntax:\n\n```ignore\ndir_spec := \"in\" / \"out\" / \"lateout\" / \"inout\" / \"inlateout\"\nreg_spec := / \"\"\noperand_expr := expr / \"_\" / expr \"=>\" expr / expr \"=>\" \"_\"\nreg_operand := dir_spec \"(\" reg_spec \")\" operand_expr\noperand := reg_operand / \"const\" const_expr / \"sym\" path\noption := \"pure\" / \"nomem\" / \"readonly\" / \"preserves_flags\" / \"noreturn\" / \"att_syntax\"\noptions := \"options(\" option *[\",\" option] [\",\"] \")\"\nasm := \"asm!(\" format_string *(\",\" format_string) *(\",\" [ident \"=\"] operand) [\",\" options] [\",\"] \")\"\n```\n\nThe macro will initially be supported only on ARM, AArch64, Hexagon, x86, x86-64 and RISC-V targets. Support for more targets may be added in the future. The compiler will emit an error if `asm!` is used on an unsupported target.\n\n[format-syntax]: https://doc.rust-lang.org/std/fmt/#syntax\n\n## Template string arguments\n\nThe assembler template uses the same syntax as [format strings][format-syntax] (i.e. placeholders are specified by curly braces). The corresponding arguments are accessed in order, by index, or by name. However, implicit named arguments (introduced by [RFC #2795][rfc-2795]) are not supported.\n\nAn `asm!` invocation may have one or more template string arguments; an `asm!` with multiple template string arguments is treated as if all the strings were concatenated with a `\\n` between them. The expected usage is for each template string argument to correspond to a line of assembly code. All template string arguments must appear before any other arguments.\n\nAs with format strings, named arguments must appear after positional arguments. Explicit register operands must appear at the end of the operand list, after named arguments if any.\n\nExplicit register operands cannot be used by placeholders in the template string. All other named and positional operands must appear at least once in the template string, otherwise a compiler error is generated.\n\nThe exact assembly code syntax is target-specific and opaque to the compiler except for the way operands are substituted into the template string to form the code passed to the assembler.\n\nThe 5 targets specified in this RFC (x86, ARM, AArch64, RISC-V, Hexagon) all use the assembly code syntax of the GNU assembler (GAS). On x86, the `.intel_syntax noprefix` mode of GAS is used by default. On ARM, the `.syntax unified` mode is used. These targets impose an additional restriction on the assembly code: any assembler state (e.g. the current section which can be changed with `.section`) must be restored to its original value at the end of the asm string. Assembly code that does not conform to the GAS syntax will result in assembler-specific behavior.\n\n[rfc-2795]: https://github.com/rust-lang/rfcs/pull/2795\n\n## Operand type\n\nSeveral types of operands are supported:\n\n* `in() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain the value of `` at the start of the asm code.\n - The allocated register must contain the same value at the end of the asm code (except if a `lateout` is allocated to the same register).\n* `out() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain an undefined value at the start of the asm code.\n - `` must be a (possibly uninitialized) place expression, to which the contents of the allocated register is written to at the end of the asm code.\n - An underscore (`_`) may be specified instead of an expression, which will cause the contents of the register to be discarded at the end of the asm code (effectively acting as a clobber).\n* `lateout() `\n - Identical to `out` except that the register allocator can reuse a register allocated to an `in`.\n - You should only write to the register after all inputs are read, otherwise you may clobber an input.\n* `inout() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain the value of `` at the start of the asm code.\n - `` must be a mutable initialized place expression, to which the contents of the allocated register is written to at the end of the asm code.\n* `inout() => `\n - Same as `inout` except that the initial value of the register is taken from the value of ``.\n - `` must be a (possibly uninitialized) place expression, to which the contents of the allocated register is written to at the end of the asm code.\n - An underscore (`_`) may be specified instead of an expression for ``, which will cause the contents of the register to be discarded at the end of the asm code (effectively acting as a clobber).\n - `` and `` may have different types.\n* `inlateout() ` / `inlateout() => `\n - Identical to `inout` except that the register allocator can reuse a register allocated to an `in` (this can happen if the compiler knows the `in` has the same initial value as the `inlateout`).\n - You should only write to the register after all inputs are read, otherwise you may clobber an input.\n* `const `\n - `` must be an integer or floating-point constant expression.\n - The value of the expression is formatted as a string and substituted directly into the asm template string.\n* `sym `\n - `` must refer to a `fn` or `static`.\n - A mangled symbol name referring to the item is substituted into the asm template string.\n - The substituted string does not include any modifiers (e.g. GOT, PLT, relocations, etc).\n - `` is allowed to point to a `#[thread_local]` static, in which case the asm code can combine the symbol with relocations (e.g. `@plt`, `@TPOFF`) to read from thread-local data.\n\nOperand expressions are evaluated from left to right, just like function call arguments. After the `asm!` has executed, outputs are written to in left to right order. This is significant if two outputs point to the same place: that place will contain the value of the rightmost output.\n\n## Register operands\n\nInput and output operands can be specified either as an explicit register or as a register class from which the register allocator can select a register. Explicit registers are specified as string literals (e.g. `\"eax\"`) while register classes are specified as identifiers (e.g. `reg`). Using string literals for register names enables support for architectures that use special characters in register names, such as MIPS (`$0`, `$1`, etc).\n\nNote that explicit registers treat register aliases (e.g. `r14` vs `lr` on ARM) and smaller views of a register (e.g. `eax` vs `rax`) as equivalent to the base register. It is a compile-time error to use the same explicit register for two input operands or two output operands. Additionally, it is also a compile-time error to use overlapping registers (e.g. ARM VFP) in input operands or in output operands.\n\nOnly the following types are allowed as operands for inline assembly:\n- Integers (signed and unsigned)\n- Floating-point numbers\n- Pointers (thin only)\n- Function pointers\n- SIMD vectors (structs defined with `#[repr(simd)]` and which implement `Copy`). This includes architecture-specific vector types defined in `std::arch` such as `__m128` (x86) or `int8x16_t` (ARM).\n\nHere is the list of currently supported register classes:\n\n| Architecture | Register class | Registers | LLVM constraint code |\n| ------------ | -------------- | --------- | -------------------- |\n| x86 | `reg` | `ax`, `bx`, `cx`, `dx`, `si`, `di`, `r[8-15]` (x86-64 only) | `r` |\n| x86 | `reg_abcd` | `ax`, `bx`, `cx`, `dx` | `Q` |\n| x86-32 | `reg_byte` | `al`, `bl`, `cl`, `dl`, `ah`, `bh`, `ch`, `dh` | `q` |\n| x86-64 | `reg_byte` | `al`, `bl`, `cl`, `dl`, `sil`, `dil`, `r[8-15]b`, `ah`\\*, `bh`\\*, `ch`\\*, `dh`\\* | `q` |\n| x86 | `xmm_reg` | `xmm[0-7]` (x86) `xmm[0-15]` (x86-64) | `x` |\n| x86 | `ymm_reg` | `ymm[0-7]` (x86) `ymm[0-15]` (x86-64) | `x` |\n| x86 | `zmm_reg` | `zmm[0-7]` (x86) `zmm[0-31]` (x86-64) | `v` |\n| x86 | `kreg` | `k[1-7]` | `Yk` |\n| AArch64 | `reg` | `x[0-28]`, `x30` | `r` |\n| AArch64 | `vreg` | `v[0-31]` | `w` |\n| AArch64 | `vreg_low16` | `v[0-15]` | `x` |\n| ARM | `reg` | `r[0-5]` `r7`\\*, `r[8-10]`, `r11`\\*, `r12`, `r14` | `r` |\n| ARM (Thumb) | `reg_thumb` | `r[0-r7]` | `l` |\n| ARM (ARM) | `reg_thumb` | `r[0-r10]`, `r12`, `r14` | `l` |\n| ARM | `sreg` | `s[0-31]` | `t` |\n| ARM | `sreg_low16` | `s[0-15]` | `x` |\n| ARM | `dreg` | `d[0-31]` | `w` |\n| ARM | `dreg_low16` | `d[0-15]` | `t` |\n| ARM | `dreg_low8` | `d[0-8]` | `x` |\n| ARM | `qreg` | `q[0-15]` | `w` |\n| ARM | `qreg_low8` | `q[0-7]` | `t` |\n| ARM | `qreg_low4` | `q[0-3]` | `x` |\n| NVPTX | `reg16` | None\\* | `h` |\n| NVPTX | `reg32` | None\\* | `r` |\n| NVPTX | `reg64` | None\\* | `l` |\n| RISC-V | `reg` | `x1`, `x[5-7]`, `x[9-15]`, `x[16-31]` (non-RV32E) | `r` |\n| RISC-V | `freg` | `f[0-31]` | `f` |\n| Hexagon | `reg` | `r[0-28]` | `r` |\n\n> **Note**: On x86 we treat `reg_byte` differently from `reg` because the compiler can allocate `al` and `ah` separately whereas `reg` reserves the whole register.\n>\n> Note #2: On x86-64 the high byte registers (e.g. `ah`) are only available when used as an explicit register. Specifying the `reg_byte` register class for an operand will always allocate a low byte register.\n>\n> Note #3: NVPTX doesn't have a fixed register set, so named registers are not supported.\n>\n> Note #4: On ARM the frame pointer is either `r7` or `r11` depending on the platform.\n\nAdditional register classes may be added in the future based on demand (e.g. MMX, x87, etc).\n\nEach register class has constraints on which value types they can be used with. This is necessary because the way a value is loaded into a register depends on its type. For example, on big-endian systems, loading a `i32x4` and a `i8x16` into a SIMD register may result in different register contents even if the byte-wise memory representation of both values is identical. The availability of supported types for a particular register class may depend on what target features are currently enabled.\n\n| Architecture | Register class | Target feature | Allowed types |\n| ------------ | -------------- | -------------- | ------------- |\n| x86-32 | `reg` | None | `i16`, `i32`, `f32` |\n| x86-64 | `reg` | None | `i16`, `i32`, `f32`, `i64`, `f64` |\n| x86 | `reg_byte` | None | `i8` |\n| x86 | `xmm_reg` | `sse` | `i32`, `f32`, `i64`, `f64`,

The only exception is the `freg` register class on RISC-V where `f32` values are NaN-boxed in a `f64` as required by the RISC-V architecture.\n\nWhen separate input and output expressions are specified for an `inout` operand, both expressions must have the same type. The only exception is if both operands are pointers or integers, in which case they are only required to have the same size. This restriction exists because the register allocators in LLVM and GCC sometimes cannot handle tied operands with different types.\n\n## Register names\n\nSome registers have multiple names.

The frame pointer cannot be used as an input or output. |\n| ARM | `r6` | `r6` is used internally by LLVM as a base pointer and therefore cannot be used as an input or output. |\n| x86 | `k0` | This is a constant zero register which can't be modified. |\n| x86 | `ip` | This is the program counter, not a real register. |\n| x86 | `mm[0-7]` | MMX registers are not currently supported (but may be in the future). |\n| x86 | `st([0-7])` | x87 registers are not currently supported (but may be in the future). |\n| AArch64 | `xzr` | This is a constant zero register which can't be modified. |\n| ARM | `pc` | This is the program counter, not a real register. |\n| RISC-V | `x0` | This is a constant zero register which can't be modified. |\n| RISC-V | `gp`, `tp` | These registers are reserved and cannot be used as inputs or outputs. |\n| Hexagon | `lr` | This is the link register which cannot be used as an input or output. |\n\nIn some cases LLVM will allocate a \"reserved register\" for `reg` operands even though this register cannot be explicitly specified. Assembly code making use of reserved registers should be careful since `reg` operands may alias with those registers. Reserved registers are:\n- The frame pointer on all architectures.\n- `r6` on ARM.\n\n## Template modifiers\n\nThe placeholders can be augmented by modifiers which are specified after the `:` in the curly braces. These modifiers do not affect register allocation, but change the way operands are formatted when inserted into the template string. Only one modifier is allowed per template placeholder.\n\nThe supported modifiers are a subset of LLVM's (and GCC's) [asm template argument modifiers][llvm-argmod], but do not use the same letter codes.\n\n| Architecture | Register class | Modifier | Example output | LLVM modifier |\n| ------------ | -------------- | -------- | -------------- | ------------- |\n| x86-32 | `reg` | None | `eax` | `k` |\n| x86-64 | `reg` | None | `rax` | `q` |\n| x86-32 | `reg_abcd` | `l` | `al` | `b` |\n| x86-64 | `reg` | `l` | `al` | `b` |\n| x86 | `reg_abcd` | `h` | `ah` | `h` |\n| x86 | `reg` | `x` | `ax` | `w` |\n| x86 | `reg` | `e` | `eax` | `k` |\n| x86-64 | `reg` | `r` | `rax` | `q` |\n| x86 | `reg_byte` | None | `al` / `ah` | None |\n| x86 | `xmm_reg` | None | `xmm0` | `x` |\n| x86 | `ymm_reg` | None | `ymm0` | `t` |\n| x86 | `zmm_reg` | None | `zmm0` | `g` |\n| x86 | `*mm_reg` | `x` | `xmm0` | `x` |\n| x86 | `*mm_reg` | `y` | `ymm0` | `t` |\n| x86 | `*mm_reg` | `z` | `zmm0` | `g` |\n| x86 | `kreg` | None | `k1` | None |\n| AArch64 | `reg` | None | `x0` | `x` |\n| AArch64 | `reg` | `w` | `w0` | `w` |\n| AArch64 | `reg` | `x` | `x0` | `x` |\n| AArch64 | `vreg` | None | `v0` | None |\n| AArch64 | `vreg` | `v` | `v0` | None |\n| AArch64 | `vreg` | `b` | `b0` | `b` |\n| AArch64 | `vreg` | `h` | `h0` | `h` |\n| AArch64 | `vreg` | `s` | `s0` | `s` |\n| AArch64 | `vreg` | `d` | `d0` | `d` |\n| AArch64 | `vreg` | `q` | `q0` | `q` |\n| ARM | `reg` | None | `r0` | None |\n| ARM | `sreg` | None | `s0` | None |\n| ARM | `dreg` | None | `d0` | `P` |\n| ARM | `qreg` | None | `q0` | `q` |\n| ARM | `qreg` | `e` / `f` | `d0` / `d1` | `e` / `f` |\n| NVPTX | `reg16` | None | `rs0` | None |\n| NVPTX | `reg32` | None | `r0` | None |\n| NVPTX | `reg64` | None | `rd0` | None |\n| RISC-V | `reg` | None | `x1` | None |\n| RISC-V | `freg` | None | `f0` | None |\n| Hexagon | `reg` | None | `r0` | None |\n\n> Notes:\n> - on ARM `e` / `f`: this prints the low or high doubleword register name of a NEON quad (128-bit) register.\n> - on x86: our behavior for `reg` with no modifiers differs from what GCC does. GCC will infer the modifier based on the operand value type, while we default to the full register size.\n> - on x86 `xmm_reg`: the `x`, `t` and `g` LLVM modifiers are not yet implemented in LLVM (they are supported by GCC only), but this should be a simple change.\n\nAs stated in the previous section, passing an input value smaller than the register width will result in the upper bits of the register containing undefined values. This is not a problem if the inline asm only accesses the lower bits of the register, which can be done by using a template modifier to use a subregister name in the asm code (e.g. `ax` instead of `rax`). Since this an easy pitfall, the compiler will suggest a template modifier to use where appropriate given the input type. If all references to an operand already have modifiers then the warning is suppressed for that operand.\n\n[llvm-argmod]: http://llvm.org/docs/LangRef.html#asm-template-argument-modifiers\n\n## Options\n\nFlags are used to further influence the behavior of the inline assembly block.\nCurrently the following options are defined:\n- `pure`: The `asm` block has no side effects, and its outputs depend only on its direct inputs (i.e. the values themselves, not what they point to) or values read from memory (unless the `nomem` options is also set). This allows the compiler to execute the `asm` block fewer times than specified in the program (e.g. by hoisting it out of a loop) or even eliminate it entirely if the outputs are not used.\n- `nomem`: The `asm` blocks does not read or write to any memory. This allows the compiler to cache the values of modified global variables in registers across the `asm` block since it knows that they are not read or written to by the `asm`.\n- `readonly`: The `asm` block does not write to any memory. This allows the compiler to cache the values of unmodified global variables in registers across the `asm` block since it knows that they are not written to by the `asm`.\n- `preserves_flags`: The `asm` block does not modify the flags register (defined in the rules below). This allows the compiler to avoid recomputing the condition flags after the `asm` block.\n- `noreturn`: The `asm` block never returns, and its return type is defined as `!` (never). Behavior is undefined if execution falls through past the end of the asm code. A `noreturn` asm block behaves just like a function which doesn't return; notably, local variables in scope are not dropped before it is invoked.\n- `nostack`: The `asm` block does not push data to the stack, or write to the stack red-zone (if supported by the target). If this option is *not* used then the stack pointer is guaranteed to be suitably aligned (according to the target ABI) for a function call.\n- `att_syntax`: This option is only valid on x86, and causes the assembler to use the `.att_syntax prefix` mode of the GNU assembler. Register operands are substituted in with a leading `%`.\n\nThe compiler performs some additional checks on options:\n- The `nomem` and `readonly` options are mutually exclusive: it is a compile-time error to specify both.\n- The `pure` option must be combined with either the `nomem` or `readonly` options, otherwise a compile-time error is emitted.\n- It is a compile-time error to specify `pure` on an asm block with no outputs or only discarded outputs (`_`).\n- It is a compile-time error to specify `noreturn` on an asm block with outputs.\n\n## Rules for inline assembly\n\n- Any registers not specified as inputs will contain an undefined value on entry to the asm block.\n - An \"undefined value\" in the context of inline assembly means that the register can (non-deterministically) have any one of the possible values allowed by the architecture. Notably it is not the same as an LLVM `undef` which can have a different value every time you read it (since such a concept does not exist in assembly code).\n- Any registers not specified as outputs must have the same value upon exiting the asm block as they had on entry, otherwise behavior is undefined.\n - This only applies to registers which can be specified as an input or output. Other registers follow target-specific rules.\n - Note that a `lateout` may be allocated to the same register as an `in`, in which case this rule does not apply. Code should not rely on this however since it depends on the results of register allocation.\n- Behavior is undefined if execution unwinds out of an asm block.\n - This also applies if the assembly code calls a function which then unwinds.\n- The set of memory locations that assembly code is allowed the read and write are the same as those allowed for an FFI function.\n - Refer to the unsafe code guidelines for the exact rules.\n - If the `readonly` option is set, then only memory reads are allowed.\n - If the `nomem` option is set then no reads or writes to memory are allowed.\n - These rules do not apply to memory which is private to the asm code, such as stack space allocated within the asm block.\n- The compiler cannot assume that the instructions in the asm are the ones that will actually end up executed.\n - This effectively means that the compiler must treat the `asm!` as a black box and only take the interface specification into account, not the instructions themselves.\n - Runtime code patching is allowed, via target-specific mechanisms (outside the scope of this RFC).\n- Unless the `nostack` option is set, asm code is allowed to use stack space below the stack pointer.\n - On entry to the asm block the stack pointer is guaranteed to be suitably aligned (according to the target ABI) for a function call.\n - You are responsible for making sure you don't overflow the stack (e.g. use stack probing to ensure you hit a guard page).\n - You should adjust the stack pointer when allocating stack memory as required by the target ABI.\n - The stack pointer must be restored to its original value before leaving the asm block.\n- If the `noreturn` option is set then behavior is undefined if execution falls through to the end of the asm block.\n- If the `pure` option is set then behavior is undefined if the `asm` has side-effects other than its direct outputs. Behavior is also undefined if two executions of the `asm` code with the same inputs result in different outputs.\n - When used with the `nomem` option, \"inputs\" are just the direct inputs of the `asm!`.\n - When used with the `readonly` option, \"inputs\" comprise the direct inputs of the `asm!` and any memory that the `asm!` block is allowed to read.\n- These flags registers must be restored upon exiting the asm block if the `preserves_flags` option is set:\n - x86\n - Status flags in `EFLAGS` (CF, PF, AF, ZF, SF, OF).\n - Floating-point status word (all).\n - Floating-point exception flags in `MXCSR` (PE, UE, OE, ZE, DE, IE).\n - ARM\n - Condition flags in `CPSR` (N, Z, C, V)\n - Saturation flag in `CPSR` (Q)\n - Greater than or equal flags in `CPSR` (GE).\n - Condition flags in `FPSCR` (N, Z, C, V)\n - Saturation flag in `FPSCR` (QC)\n - Floating-point exception flags in `FPSCR` (IDC, IXC, UFC, OFC, DZC, IOC).\n - AArch64\n - Condition flags (`NZCV` register).\n - Floating-point status (`FPSR` register).\n - RISC-V\n - Floating-point exception flags in `fcsr` (`fflags`).\n- On x86, the direction flag (DF in `EFLAGS`) is clear on entry to an asm block and must be clear on exit.\n - Behavior is undefined if the direction flag is set on exiting an asm block.\n- The requirement of restoring the stack pointer and non-output registers to their original value only applies when exiting an `asm!` block.\n - This means that `asm!` blocks that never return (even if not marked `noreturn`) don't need to preserve these registers.\n - When returning to a different `asm!` block than you entered (e.g. for context switching), these registers must contain the value they had upon entering the `asm!` block that you are *exiting*.\n - You cannot exit an `asm!` block that has not been entered. Neither can you exit an `asm!` block that has already been exited.\n - You are responsible for switching any target-specific state (e.g. thread-local storage, stack bounds).\n - The set of memory locations that you may access is the intersection of those allowed by the `asm!` blocks you entered and exited.\n- You cannot assume that an `asm!` block will appear exactly once in the output binary. The compiler is allowed to instantiate multiple copies of the `asm!` block, for example when the function containing it is inlined in multiple places.\n - As a consequence, you should only use [local labels] inside inline assembly code. Defining symbols in assembly code may lead to assembler and/or linker errors due to duplicate symbol definitions.\n\n> **Note**: As a general rule, the flags covered by `preserves_flags` are those which are *not* preserved when performing a function call.\n\n[local labels]: https://sourceware.org/binutils/docs/as/Symbol-Names.html#Local-Labels\n" } , LintCompletion { label : "is_sorted" ,

This is useful for very low level programming, where\nwhich register you use is important:\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# unsafe fn read_byte_in(port: u16) -> u8 {\nlet result: u8;\nllvm_asm!(\"in %dx, %al\" : \"={al}\"(result) : \"{dx}\"(port));\nresult\n# }\n```\n\n## Clobbers\n\nSome instructions modify registers which might otherwise have held\ndifferent values so we use the clobbers list to indicate to the\ncompiler not to assume any values loaded into those registers will\nstay valid.\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# fn main() { unsafe {\n// Put the value 0x200 in eax:\nllvm_asm!(\"mov $$0x200, %eax\" : /* no outputs */ : /* no inputs */ : \"eax\");\n# } }\n# #[cfg(not(any(target_arch = \"x86\", target_arch = \"x86_64\")))]\n# fn main() {}\n```\n\nInput and output registers need not be listed since that information\nis already communicated by the given constraints. Otherwise, any other\nregisters used either implicitly or explicitly should be listed.\n\nIf the assembly changes the condition code register `cc` should be\nspecified as one of the clobbers. Similarly, if the assembly modifies\nmemory, `memory` should also be specified.\n\n## Options\n\nThe last section, `options` is specific to Rust. The format is comma\nseparated literal strings (i.e. `:\"foo\", \"bar\", \"baz\"`). It's used to\nspecify some extra info about the inline assembly:\n\nCurrent valid options are:\n\n1. *volatile* - specifying this is analogous to\n `__asm__ __volatile__ (...)` in gcc/clang.\n2. *alignstack* - certain instructions expect the stack to be\n aligned a certain way (i.e. SSE) and specifying this indicates to\n the compiler to insert its usual stack alignment code\n3. *intel* - use intel syntax instead of the default AT&T.\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# fn main() {\nlet result: i32;\nunsafe {\n llvm_asm!(\"mov eax, 2\" : \"={eax}\"(result) : : : \"intel\")\n}\nprintln!(\"eax is currently {}\", result);\n# }\n# #[cfg(not(any(target_arch = \"x86\", target_arch = \"x86_64\")))]\n# fn main() {}\n```\n\n## More Information\n\nThe current implementation of the `llvm_asm!` macro is a direct binding to [LLVM's\ninline assembler expressions][llvm-docs], so be sure to check out [their\ndocumentation as well][llvm-docs] for more information about clobbers,\nconstraints, etc.\n\n[llvm-docs]: http://llvm.org/docs/LangRef.html#inline-assembler-expressions\n\nIf you need more power and don't mind losing some of the niceties of\n`llvm_asm!`, check out [global_asm](global-asm.md).\n" } ] ; +pub const UNSTABLE_FEATURE_DESCRIPTOR : & [ LintCompletion ] = & [ LintCompletion { label : "crate_visibility_modifier" , description : "# `crate_visibility_modifier`\n\nThe tracking issue for this feature is: [#53120]\n\n[#53120]: https://github.com/rust-lang/rust/issues/53120\n\n-----\n\nThe `crate_visibility_modifier` feature allows the `crate` keyword to be used\nas a visibility modifier synonymous to `pub(crate)`, indicating that a type\n(function, _&c._) is to be visible to the entire enclosing crate, but not to\nother crates.\n\n```rust\n#![feature(crate_visibility_modifier)]\n\ncrate struct Foo {\n bar: usize,\n}\n```\n" } , LintCompletion { label : "abi_thiscall" , description : "# `abi_thiscall`\n\nThe tracking issue for this feature is: [#42202]\n\n[#42202]: https://github.com/rust-lang/rust/issues/42202\n\n------------------------\n\nThe MSVC ABI on x86 Windows uses the `thiscall` calling convention for C++\ninstance methods by default; it is identical to the usual (C) calling\nconvention on x86 Windows except that the first parameter of the method,\nthe `this` pointer, is passed in the ECX register.\n" } , LintCompletion { label : "infer_static_outlives_requirements" , description : "# `infer_static_outlives_requirements`\n\nThe tracking issue for this feature is: [#54185]\n\n[#54185]: https://github.com/rust-lang/rust/issues/54185\n\n------------------------\nThe `infer_static_outlives_requirements` feature indicates that certain\n`'static` outlives requirements can be inferred by the compiler rather than\nstating them explicitly.\n\nNote: It is an accompanying feature to `infer_outlives_requirements`,\nwhich must be enabled to infer outlives requirements.\n\nFor example, currently generic struct definitions that contain\nreferences, require where-clauses of the form T: 'static.

A generator is a \"resumable function\" that syntactically\nresembles a closure but compiles to much different semantics in the compiler\nitself. The primary feature of a generator is that it can be suspended during\nexecution to be resumed at a later date. Generators use the `yield` keyword to\n\"return\", and then the caller can `resume` a generator to resume execution just\nafter the `yield` keyword.\n\nGenerators are an extra-unstable feature in the compiler right now. Added in\n[RFC 2033] they're mostly intended right now as a information/constraint\ngathering phase. The intent is that experimentation can happen on the nightly\ncompiler before actual stabilization. A further RFC will be required to\nstabilize generators/coroutines and will likely contain at least a few small\ntweaks to the overall design.\n\n[RFC 2033]: https://github.com/rust-lang/rfcs/pull/2033\n\nA syntactical example of a generator is:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::{Generator, GeneratorState};\nuse std::pin::Pin;\n\nfn main() {\n let mut generator = || {\n yield 1;\n return \"foo\"\n };\n\n match Pin::new(&mut generator).resume(()) {\n GeneratorState::Yielded(1) => {}\n _ => panic!(\"unexpected value from resume\"),\n }\n match Pin::new(&mut generator).resume(()) {\n GeneratorState::Complete(\"foo\") => {}\n _ => panic!(\"unexpected value from resume\"),\n }\n}\n```\n\nGenerators are closure-like literals which can contain a `yield` statement. The\n`yield` statement takes an optional expression of a value to yield out of the\ngenerator. All generator literals implement the `Generator` trait in the\n`std::ops` module. The `Generator` trait has one main method, `resume`, which\nresumes execution of the generator at the previous suspension point.\n\nAn example of the control flow of generators is that the following example\nprints all numbers in order:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::Generator;\nuse std::pin::Pin;\n\nfn main() {\n let mut generator = || {\n println!(\"2\");\n yield;\n println!(\"4\");\n };\n\n println!(\"1\");\n Pin::new(&mut generator).resume(());\n println!(\"3\");\n Pin::new(&mut generator).resume(());\n println!(\"5\");\n}\n```\n\nAt this time the main intended use case of generators is an implementation\nprimitive for async/await syntax, but generators will likely be extended to\nergonomic implementations of iterators and other primitives in the future.\nFeedback on the design and usage is always appreciated!\n\n### The `Generator` trait\n\nThe `Generator` trait in `std::ops` currently looks like:\n\n```rust\n# #![feature(arbitrary_self_types, generator_trait)]\n# use std::ops::GeneratorState;\n# use std::pin::Pin;\n\npub trait Generator {\n type Yield;\n type Return;\n fn resume(self: Pin<&mut Self>, resume: R) -> GeneratorState;\n}\n```\n\nThe `Generator::Yield` type is the type of values that can be yielded with the\n`yield` statement. The `Generator::Return` type is the returned type of the\ngenerator. This is typically the last expression in a generator's definition or\nany value passed to `return` in a generator. The `resume` function is the entry\npoint for executing the `Generator` itself.\n\nThe return value of `resume`, `GeneratorState`, looks like:\n\n```rust\npub enum GeneratorState {\n Yielded(Y),\n Complete(R),\n}\n```\n\nThe `Yielded` variant indicates that the generator can later be resumed. This\ncorresponds to a `yield` point in a generator. The `Complete` variant indicates\nthat the generator is complete and cannot be resumed again. Calling `resume`\nafter a generator has returned `Complete` will likely result in a panic of the\nprogram.\n\n### Closure-like semantics\n\nThe closure-like syntax for generators alludes to the fact that they also have\nclosure-like semantics. Namely:\n\n* When created, a generator executes no code. A closure literal does not\n actually execute any of the closure's code on construction, and similarly a\n generator literal does not execute any code inside the generator when\n constructed.\n\n* Generators can capture outer variables by reference or by move, and this can\n be tweaked with the `move` keyword at the beginning of the closure. Like\n closures all generators will have an implicit environment which is inferred by\n the compiler. Outer variables can be moved into a generator for use as the\n generator progresses.\n\n* Generator literals produce a value with a unique type which implements the\n `std::ops::Generator` trait. This allows actual execution of the generator\n through the `Generator::resume` method as well as also naming it in return\n types and such.\n\n* Traits like `Send` and `Sync` are automatically implemented for a `Generator`\n depending on the captured variables of the environment. Unlike closures,\n generators also depend on variables live across suspension points. This means\n that although the ambient environment may be `Send` or `Sync`, the generator\n itself may not be due to internal variables live across `yield` points being\n not-`Send` or not-`Sync`. Note that generators do\n not implement traits like `Copy` or `Clone` automatically.\n\n* Whenever a generator is dropped it will drop all captured environment\n variables.\n\n### Generators as state machines\n\nIn the compiler, generators are currently compiled as state machines. Each\n`yield` expression will correspond to a different state that stores all live\nvariables over that suspension point. Resumption of a generator will dispatch on\nthe current state and then execute internally until a `yield` is reached, at\nwhich point all state is saved off in the generator and a value is returned.\n\nLet's take a look at an example to see what's going on here:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::Generator;\nuse std::pin::Pin;\n\nfn main() {\n let ret = \"foo\";\n let mut generator = move || {\n yield 1;\n return ret\n };\n\n Pin::new(&mut generator).resume(());\n Pin::new(&mut generator).resume(());\n}\n```\n\nThis generator literal will compile down to something similar to:\n\n```rust\n#![feature(arbitrary_self_types, generators, generator_trait)]\n\nuse std::ops::{Generator, GeneratorState};\nuse std::pin::Pin;\n\nfn main() {\n let ret = \"foo\";\n let mut generator = {\n enum __Generator {\n Start(&'static str),\n Yield1(&'static str),\n Done,\n }\n\n impl Generator for __Generator {\n type Yield = i32;\n type Return = &'static str;\n\n fn resume(mut self: Pin<&mut Self>, resume: ()) -> GeneratorState {\n use std::mem;\n match mem::replace(&mut *self, __Generator::Done) {\n __Generator::Start(s) => {\n *self = __Generator::Yield1(s);\n GeneratorState::Yielded(1)\n }\n\n __Generator::Yield1(s) => {\n *self = __Generator::Done;\n GeneratorState::Complete(s)\n }\n\n __Generator::Done => {\n panic!(\"generator resumed after completion\")\n }\n }\n }\n }\n\n __Generator::Start(ret)\n };\n\n Pin::new(&mut generator).resume(());\n Pin::new(&mut generator).resume(());\n}\n```\n\nNotably here we can see that the compiler is generating a fresh type,\n`__Generator` in this case. This type has a number of states (represented here\nas an `enum`) corresponding to each of the conceptual states of the generator.\nAt the beginning we're closing over our outer variable `foo` and then that\nvariable is also live over the `yield` point, so it's stored in both states.\n\nWhen the generator starts it'll immediately yield 1, but it saves off its state\njust before it does so indicating that it has reached the yield point.

The syntax isn't final, either. We may need an alternative syntax for Rust 2015 because, in Rust 2015, expressions like `[e; dyn(1)]` would be ambiguous. One possible alternative proposed in the RFC is `[e; n]`: if `n` captures one or more local variables, then it is considered as `[e; dyn n]`.\n\n## Advisory on stack usage\n\nIt's advised not to casually use the `#![feature(unsized_locals)]` feature. Typical use-cases are:\n\n- When you need a by-value trait objects.\n- When you really need a fast allocation of small temporary arrays.\n\nAnother pitfall is repetitive allocation and temporaries. Currently the compiler simply extends the stack frame every time it encounters an unsized assignment. So for example, the code\n\n```rust\n#![feature(unsized_locals)]\n\nfn main() {\n let x: Box<[i32]> = Box::new([1, 2, 3, 4, 5]);\n let _x = {{{{{{{{{{*x}}}}}}}}}};\n}\n```\n\nand the code\n\n```rust\n#![feature(unsized_locals)]\n\nfn main() {\n for _ in 0..10 {\n let x: Box<[i32]> = Box::new([1, 2, 3, 4, 5]);\n let _x = *x;\n }\n}\n```\n\nwill unnecessarily extend the stack frame.\n" } , LintCompletion { label : "or_patterns" , description : "# `or_patterns`\n\nThe tracking issue for this feature is: [#54883]\n\n[#54883]: https://github.com/rust-lang/rust/issues/54883\n\n------------------------\n\nThe `or_pattern` language feature allows `|` to be arbitrarily nested within\na pattern, for example, `Some(A(0) | B(1 | 2))` becomes a valid pattern.\n\n## Examples\n\n```rust,ignore\n#![feature(or_patterns)]\n\npub enum Foo {\n Bar,\n Baz,\n Quux,\n}\n\npub fn example(maybe_foo: Option) {\n match maybe_foo {\n Some(Foo::Bar | Foo::Baz) => {\n println!(\"The value contained `Bar` or `Baz`\");\n }\n Some(_) => {\n println!(\"The value did not contain `Bar` or `Baz`\");\n }\n None => {\n println!(\"The value was `None`\");\n }\n }\n}\n```\n" } , LintCompletion { label : "member_constraints" , description : "# `member_constraints`\n\nThe tracking issue for this feature is: [#61997]\n\n[#61997]: https://github.com/rust-lang/rust/issues/61997\n\n------------------------\n\nThe `member_constraints` feature gate lets you use `impl Trait` syntax with\nmultiple unrelated lifetime parameters.\n\nA simple example is:\n\n```rust\n#![feature(member_constraints)]\n\ntrait Trait<'a, 'b> { }\nimpl Trait<'_, '_> for T {}\n\nfn foo<'a, 'b>(x: &'a u32, y: &'b u32) -> impl Trait<'a, 'b> {\n (x, y)\n}\n\nfn main() { }\n```\n\nWithout the `member_constraints` feature gate, the above example is an\nerror because both `'a` and `'b` appear in the impl Trait bounds, but\nneither outlives the other.\n" } , LintCompletion { label : "optin_builtin_traits" , description : "# `optin_builtin_traits`\n\nThe tracking issue for this feature is [#13231] \n\n[#13231]: https://github.com/rust-lang/rust/issues/13231\n\n----\n\nThe `optin_builtin_traits` feature gate allows you to define auto traits.\n\nAuto traits, like [`Send`] or [`Sync`] in the standard library, are marker traits\nthat are automatically implemented for every type, unless the type, or a type it contains, \nhas explicitly opted out via a negative impl.

These automatic impls contain a where clause for each field\nof the form `T: AutoTrait`, where `T` is the type of the field and\n`AutoTrait` is the auto trait in question. As an example, consider the\nstruct `List` and the auto trait `Send`:\n\n```rust\nstruct List {\n data: T,\n next: Option>>,\n}\n```\n\nPresuming that there is no explicit impl of `Send` for `List`, the\ncompiler will supply an automatic impl of the form:\n\n```rust\nstruct List {\n data: T,\n next: Option>>,\n}\n\nunsafe impl Send for List\nwhere\n T: Send, // from the field `data`\n Option>>: Send, // from the field `next`\n{ }\n```\n\nExplicit impls may be either positive or negative. They take the form:\n\n```rust,ignore\nimpl<...> AutoTrait for StructName<..> { }\nimpl<...> !AutoTrait for StructName<..> { }\n```\n\n## Coinduction: Auto traits permit cyclic matching\n\nUnlike ordinary trait matching, auto traits are **coinductive**. This\nmeans, in short, that cycles which occur in trait matching are\nconsidered ok. As an example, consider the recursive struct `List`\nintroduced in the previous section. In attempting to determine whether\n`List: Send`, we would wind up in a cycle: to apply the impl, we must\nshow that `Option>: Send`, which will in turn require\n`Box: Send` and then finally `List: Send` again. Under ordinary\ntrait matching, this cycle would be an error, but for an auto trait it\nis considered a successful match.\n\n## Items\n\nAuto traits cannot have any trait items, such as methods or associated types. This ensures that we can generate default implementations.\n\n## Supertraits\n\nAuto traits cannot have supertraits.

The marker is the attribute `#[lang = \"...\"]` and there are\nvarious different values of `...`, i.e. various different 'lang\nitems'.\n\nFor example, `Box` pointers require two lang items, one for allocation\nand one for deallocation. A freestanding program that uses the `Box`\nsugar for dynamic allocations via `malloc` and `free`:\n\n```rust,ignore\n#![feature(lang_items, box_syntax, start, libc, core_intrinsics)]\n#![no_std]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\nextern crate libc;\n\n#[lang = \"owned_box\"]\npub struct Box(*mut T);\n\n#[lang = \"exchange_malloc\"]\nunsafe fn allocate(size: usize, _align: usize) -> *mut u8 {\n let p = libc::malloc(size as libc::size_t) as *mut u8;\n\n // Check if `malloc` failed:\n if p as usize == 0 {\n intrinsics::abort();\n }\n\n p\n}\n\n#[lang = \"box_free\"]\nunsafe fn box_free(ptr: *mut T) {\n libc::free(ptr as *mut libc::c_void)\n}\n\n#[start]\nfn main(_argc: isize, _argv: *const *const u8) -> isize {\n let _x = box 1;\n\n 0\n}\n\n#[lang = \"eh_personality\"] extern fn rust_eh_personality() {}\n#[lang = \"panic_impl\"] extern fn rust_begin_panic(info: &PanicInfo) -> ! { unsafe { intrinsics::abort() } }\n#[no_mangle] pub extern fn rust_eh_register_frames () {}\n#[no_mangle] pub extern fn rust_eh_unregister_frames () {}\n```\n\nNote the use of `abort`: the `exchange_malloc` lang item is assumed to\nreturn a valid pointer, and so needs to do the check internally.\n\nOther features provided by lang items include:\n\n- overloadable operators via traits: the traits corresponding to the\n `==`, `<`, dereferencing (`*`) and `+` (etc.) operators are all\n marked with lang items; those specific four are `eq`, `ord`,\n `deref`, and `add` respectively.\n- stack unwinding and general failure; the `eh_personality`,\n `panic` and `panic_bounds_checks` lang items.\n- the traits in `std::marker` used to indicate types of\n various kinds; lang items `send`, `sync` and `copy`.\n- the marker types and variance indicators found in\n `std::marker`; lang items `covariant_type`,\n `contravariant_lifetime`, etc.\n\nLang items are loaded lazily by the compiler; e.g. if one never uses\n`Box` then there is no need to define functions for `exchange_malloc`\nand `box_free`. `rustc` will emit an error when an item is needed\nbut not found in the current crate or any that it depends on.\n\nMost lang items are defined by `libcore`, but if you're trying to build\nan executable without the standard library, you'll run into the need\nfor lang items. The rest of this page focuses on this use-case, even though\nlang items are a bit broader than that.\n\n### Using libc\n\nIn order to build a `#[no_std]` executable we will need libc as a dependency.\nWe can specify this using our `Cargo.toml` file:\n\n```toml\n[dependencies]\nlibc = { version = \"0.2.14\", default-features = false }\n```\n\nNote that the default features have been disabled. This is a critical step -\n**the default features of libc include the standard library and so must be\ndisabled.**\n\n### Writing an executable without stdlib\n\nControlling the entry point is possible in two ways: the `#[start]` attribute,\nor overriding the default shim for the C `main` function with your own.\n\nThe function marked `#[start]` is passed the command line parameters\nin the same format as C:\n\n```rust,ignore\n#![feature(lang_items, core_intrinsics)]\n#![feature(start)]\n#![no_std]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\n// Pull in the system libc library for what crt0.o likely requires.\nextern crate libc;\n\n// Entry point for this program.\n#[start]\nfn start(_argc: isize, _argv: *const *const u8) -> isize {\n 0\n}\n\n// These functions are used by the compiler, but not\n// for a bare-bones hello world. These are normally\n// provided by libstd.\n#[lang = \"eh_personality\"]\n#[no_mangle]\npub extern fn rust_eh_personality() {\n}\n\n#[lang = \"panic_impl\"]\n#[no_mangle]\npub extern fn rust_begin_panic(info: &PanicInfo) -> ! {\n unsafe { intrinsics::abort() }\n}\n```\n\nTo override the compiler-inserted `main` shim, one has to disable it\nwith `#![no_main]` and then create the appropriate symbol with the\ncorrect ABI and the correct name, which requires overriding the\ncompiler's name mangling too:\n\n```rust,ignore\n#![feature(lang_items, core_intrinsics)]\n#![feature(start)]\n#![no_std]\n#![no_main]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\n// Pull in the system libc library for what crt0.o likely requires.\nextern crate libc;\n\n// Entry point for this program.\n#[no_mangle] // ensure that this symbol is called `main` in the output\npub extern fn main(_argc: i32, _argv: *const *const u8) -> i32 {\n 0\n}\n\n// These functions are used by the compiler, but not\n// for a bare-bones hello world.

You may observe this via linker error messages\nsuch as \"```undefined reference to `__rust_probestack'```\".\n\n## More about the language items\n\nThe compiler currently makes a few assumptions about symbols which are\navailable in the executable to call. Normally these functions are provided by\nthe standard library, but without it you must define your own. These symbols\nare called \"language items\", and they each have an internal name, and then a\nsignature that an implementation must conform to.\n\nThe first of these functions, `rust_eh_personality`, is used by the failure\nmechanisms of the compiler. This is often mapped to GCC's personality function\n(see the [libstd implementation][unwind] for more information), but crates\nwhich do not trigger a panic can be assured that this function is never\ncalled.

Negative impls are a commitment not to implement the given trait for the named types.\n\n## Orphan and overlap rules\n\nNegative impls must obey the same orphan rules as a positive impl. This implies you cannot add a negative impl for types defined in upstream crates and so forth.\n\nSimilarly, negative impls cannot overlap with positive impls, again using the same \"overlap\" check that we ordinarily use to determine if two impls overlap. (Note that positive impls typically cannot overlap with one another either, except as permitted by specialization.)\n\n## Interaction with auto traits\n\nDeclaring a negative impl `impl !SomeAutoTrait for SomeType` for an\nauto-trait serves two purposes:\n\n* as with any trait, it declares that `SomeType` will never implement `SomeAutoTrait`;\n* it disables the automatic `SomeType: SomeAutoTrait` impl that would otherwise have been generated.\n\nNote that, at present, there is no way to indicate that a given type\ndoes not implement an auto trait *but that it may do so in the\nfuture*. For ordinary types, this is done by simply not declaring any\nimpl at all, but that is not an option for auto traits. A workaround\nis that one could embed a marker type as one of the fields, where the\nmarker type is `!AutoTrait`.\n\n## Immediate uses\n\nNegative impls are used to declare that `&T: !DerefMut` and `&mut T: !Clone`, as required to fix the soundness of `Pin` described in [#66544](https://github.com/rust-lang/rust/issues/66544).\n\nThis serves two purposes:\n\n* For proving the correctness of unsafe code, we can use that impl as evidence that no `DerefMut` or `Clone` impl exists.\n* It prevents downstream crates from creating such impls.\n" } , LintCompletion { label : "abi_ptx" , description : "# `abi_ptx`\n\nThe tracking issue for this feature is: [#38788]\n\n[#38788]: https://github.com/rust-lang/rust/issues/38788\n\n------------------------\n\nWhen emitting PTX code, all vanilla Rust functions (`fn`) get translated to\n\"device\" functions.

This is\ngenerally unwanted unless you are building another plugin.\n\nThe usual practice is to put compiler plugins in their own crate, separate from\nany `macro_rules!` macros or ordinary Rust code meant to be used by consumers\nof a library.\n\n# Lint plugins\n\nPlugins can extend [Rust's lint\ninfrastructure](../../reference/attributes/diagnostics.md#lint-check-attributes) with\nadditional checks for code style, safety, etc. Now let's write a plugin\n[`lint-plugin-test.rs`](https://github.com/rust-lang/rust/blob/master/src/test/ui-fulldeps/auxiliary/lint-plugin-test.rs)\nthat warns about any item named `lintme`.\n\n```rust,ignore\n#![feature(plugin_registrar)]\n#![feature(box_syntax, rustc_private)]\n\nextern crate rustc_ast;\n\n// Load rustc as a plugin to get macros\nextern crate rustc_driver;\n#[macro_use]\nextern crate rustc_lint;\n#[macro_use]\nextern crate rustc_session;\n\nuse rustc_driver::plugin::Registry;\nuse rustc_lint::{EarlyContext, EarlyLintPass, LintArray, LintContext, LintPass};\nuse rustc_ast::ast;\ndeclare_lint!(TEST_LINT, Warn, \"Warn about items named 'lintme'\");\n\ndeclare_lint_pass!(Pass => [TEST_LINT]);\n\nimpl EarlyLintPass for Pass {\n fn check_item(&mut self, cx: &EarlyContext, it: &ast::Item) {\n if it.ident.name.as_str() == \"lintme\" {\n cx.lint(TEST_LINT, |lint| {\n lint.build(\"item is named 'lintme'\").set_span(it.span).emit()\n });\n }\n }\n}\n\n#[plugin_registrar]\npub fn plugin_registrar(reg: &mut Registry) {\n reg.lint_store.register_lints(&[&TEST_LINT]);\n reg.lint_store.register_early_pass(|| box Pass);\n}\n```\n\nThen code like\n\n```rust,ignore\n#![feature(plugin)]\n#![plugin(lint_plugin_test)]\n\nfn lintme() { }\n```\n\nwill produce a compiler warning:\n\n```txt\nfoo.rs:4:1: 4:16 warning: item is named 'lintme', #[warn(test_lint)] on by default\nfoo.rs:4 fn lintme() { }\n ^~~~~~~~~~~~~~~\n```\n\nThe components of a lint plugin are:\n\n* one or more `declare_lint!` invocations, which define static `Lint` structs;\n\n* a struct holding any state needed by the lint pass (here, none);\n\n* a `LintPass`\n implementation defining how to check each syntax element. A single\n `LintPass` may call `span_lint` for several different `Lint`s, but should\n register them all through the `get_lints` method.\n\nLint passes are syntax traversals, but they run at a late stage of compilation\nwhere type information is available. `rustc`'s [built-in\nlints](https://github.com/rust-lang/rust/blob/master/src/librustc_session/lint/builtin.rs)\nmostly use the same infrastructure as lint plugins, and provide examples of how\nto access type information.\n\nLints defined by plugins are controlled by the usual [attributes and compiler\nflags](../../reference/attributes/diagnostics.md#lint-check-attributes), e.g.\n`#[allow(test_lint)]` or `-A test-lint`. These identifiers are derived from the\nfirst argument to `declare_lint!`, with appropriate case and punctuation\nconversion.\n\nYou can run `rustc -W help foo.rs` to see a list of lints known to `rustc`,\nincluding those provided by plugins loaded by `foo.rs`.\n" } , LintCompletion { label : "concat_idents" , description : "# `concat_idents`\n\nThe tracking issue for this feature is: [#29599]\n\n[#29599]: https://github.com/rust-lang/rust/issues/29599\n\n------------------------\n\nThe `concat_idents` feature adds a macro for concatenating multiple identifiers\ninto one identifier.\n\n## Examples\n\n```rust\n#![feature(concat_idents)]\n\nfn main() {\n fn foobar() -> u32 { 23 }\n let f = concat_idents!(foo, bar);\n assert_eq!(f(), 23);\n}\n```" } , LintCompletion { label : "update_panic_count" , description : "# `update_panic_count`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "fn_traits" , description : "# `fn_traits`\n\nThe tracking issue for this feature is [#29625]\n\nSee Also: [`unboxed_closures`](../language-features/unboxed-closures.md)\n\n[#29625]: https://github.com/rust-lang/rust/issues/29625\n\n----\n\nThe `fn_traits` feature allows for implementation of the [`Fn*`] traits\nfor creating custom closure-like types.\n\n[`Fn*`]: https://doc.rust-lang.org/std/ops/trait.Fn.html\n\n```rust\n#![feature(unboxed_closures)]\n#![feature(fn_traits)]\n\nstruct Adder {\n a: u32\n}\n\nimpl FnOnce<(u32, )> for Adder {\n type Output = u32;\n extern \"rust-call\" fn call_once(self, b: (u32, )) -> Self::Output {\n self.a + b.0\n }\n}\n\nfn main() {\n let adder = Adder { a: 3 };\n assert_eq!(adder(2), 5);\n}\n```\n" } , LintCompletion { label : "try_trait" , description : "# `try_trait`\n\nThe tracking issue for this feature is: [#42327]\n\n[#42327]: https://github.com/rust-lang/rust/issues/42327\n\n------------------------\n\nThis introduces a new trait `Try` for extending the `?` operator to types\nother than `Result` (a part of [RFC 1859]).

The macro is a no-frills\ninterface to LLVM's concept of [module-level inline assembly]. That is,\nall caveats applicable to LLVM's module-level inline assembly apply\nto `global_asm!`.\n\n[module-level inline assembly]: http://llvm.org/docs/LangRef.html#module-level-inline-assembly\n\n`global_asm!` fills a role not currently satisfied by either `asm!`\nor `#[naked]` functions. The programmer has _all_ features of the\nassembler at their disposal. The linker will expect to resolve any\nsymbols defined in the inline assembly, modulo any symbols marked as\nexternal. It also means syntax for directives and assembly follow the\nconventions of the assembler in your toolchain.\n\nA simple usage looks like this:\n\n```rust,ignore\n# #![feature(global_asm)]\n# you also need relevant target_arch cfgs\nglobal_asm!(include_str!(\"something_neato.s\"));\n```\n\nAnd a more complicated usage looks like this:\n\n```rust,ignore\n# #![feature(global_asm)]\n# #![cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n\npub mod sally {\n global_asm!(r#\"\n .global foo\n foo:\n jmp baz\n \"#);\n\n #[no_mangle]\n pub unsafe extern \"C\" fn baz() {}\n}\n\n// the symbols `foo` and `bar` are global, no matter where\n// `global_asm!` was used.\nextern \"C\" {\n fn foo();\n fn bar();\n}\n\npub mod harry {\n global_asm!(r#\"\n .global bar\n bar:\n jmp quux\n \"#);\n\n #[no_mangle]\n pub unsafe extern \"C\" fn quux() {}\n}\n```\n\nYou may use `global_asm!` multiple times, anywhere in your crate, in\nwhatever way suits you. The effect is as if you concatenated all\nusages and placed the larger, single usage in the crate root.\n\n------------------------\n\nIf you don't need quite as much power and flexibility as\n`global_asm!` provides, and you don't mind restricting your inline\nassembly to `fn` bodies only, you might try the\n[asm](asm.md) feature instead.\n" } , LintCompletion { label : "sort_internals" , description : "# `sort_internals`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "test" , description : "# `test`\n\nThe tracking issue for this feature is: None.\n\n------------------------\n\nThe internals of the `test` crate are unstable, behind the `test` flag. The\nmost widely used part of the `test` crate are benchmark tests, which can test\nthe performance of your code. Let's make our `src/lib.rs` look like this\n(comments elided):\n\n```rust,ignore\n#![feature(test)]\n\nextern crate test;\n\npub fn add_two(a: i32) -> i32 {\n a + 2\n}\n\n#[cfg(test)]\nmod tests {\n use super::*;\n use test::Bencher;\n\n #[test]\n fn it_works() {\n assert_eq!(4, add_two(2));\n }\n\n #[bench]\n fn bench_add_two(b: &mut Bencher) {\n b.iter(|| add_two(2));\n }\n}\n```\n\nNote the `test` feature gate, which enables this unstable feature.\n\nWe've imported the `test` crate, which contains our benchmarking support.\nWe have a new function as well, with the `bench` attribute. Unlike regular\ntests, which take no arguments, benchmark tests take a `&mut Bencher`. This\n`Bencher` provides an `iter` method, which takes a closure. This closure\ncontains the code we'd like to benchmark.\n\nWe can run benchmark tests with `cargo bench`:\n\n```bash\n$ cargo bench\n Compiling adder v0.0.1 (file:///home/steve/tmp/adder)\n Running target/release/adder-91b3e234d4ed382a\n\nrunning 2 tests\ntest tests::it_works ... ignored\ntest tests::bench_add_two ... bench: 1 ns/iter (+/- 0)\n\ntest result: ok. 0 passed; 0 failed; 1 ignored; 1 measured\n```\n\nOur non-benchmark test was ignored. You may have noticed that `cargo bench`\ntakes a bit longer than `cargo test`. This is because Rust runs our benchmark\na number of times, and then takes the average. Because we're doing so little\nwork in this example, we have a `1 ns/iter (+/- 0)`, but this would show\nthe variance if there was one.\n\nAdvice on writing benchmarks:\n\n\n* Move setup code outside the `iter` loop; only put the part you want to measure inside\n* Make the code do \"the same thing\" on each iteration; do not accumulate or change state\n* Make the outer function idempotent too; the benchmark runner is likely to run\n it many times\n* Make the inner `iter` loop short and fast so benchmark runs are fast and the\n calibrator can adjust the run-length at fine resolution\n* Make the code in the `iter` loop do something simple, to assist in pinpointing\n performance improvements (or regressions)\n\n## Gotcha: optimizations\n\nThere's another tricky part to writing benchmarks: benchmarks compiled with\noptimizations activated can be dramatically changed by the optimizer so that\nthe benchmark is no longer benchmarking what one expects. For example, the\ncompiler might recognize that some calculation has no external effects and\nremove it entirely.\n\n```rust,ignore\n#![feature(test)]\n\nextern crate test;\nuse test::Bencher;\n\n#[bench]\nfn bench_xor_1000_ints(b: &mut Bencher) {\n b.iter(|| {\n (0..1000).fold(0, |old, new| old ^ new);\n });\n}\n```\n\ngives the following results\n\n```text\nrunning 1 test\ntest bench_xor_1000_ints ... bench: 0 ns/iter (+/- 0)\n\ntest result: ok. 0 passed; 0 failed; 0 ignored; 1 measured\n```\n\nThe benchmarking runner offers two ways to avoid this. Either, the closure that\nthe `iter` method receives can return an arbitrary value which forces the\noptimizer to consider the result used and ensures it cannot remove the\ncomputation entirely. This could be done for the example above by adjusting the\n`b.iter` call to\n\n```rust\n# struct X;\n# impl X { fn iter(&self, _: F) where F: FnMut() -> T {} } let b = X;\nb.iter(|| {\n // Note lack of `;` (could also use an explicit `return`).\n (0..1000).fold(0, |old, new| old ^ new)\n});\n```\n\nOr, the other option is to call the generic `test::black_box` function, which\nis an opaque \"black box\" to the optimizer and so forces it to consider any\nargument as used.\n\n```rust\n#![feature(test)]\n\nextern crate test;\n\n# fn main() {\n# struct X;\n# impl X { fn iter(&self, _: F) where F: FnMut() -> T {} } let b = X;\nb.iter(|| {\n let n = test::black_box(1000);\n\n (0..n).fold(0, |a, b| a ^ b)\n})\n# }\n```\n\nNeither of these read or modify the value, and are very cheap for small values.\nLarger values can be passed indirectly to reduce overhead (e.g.\n`black_box(&huge_struct)`).\n\nPerforming either of the above changes gives the following benchmarking results\n\n```text\nrunning 1 test\ntest bench_xor_1000_ints ... bench: 131 ns/iter (+/- 3)\n\ntest result: ok. 0 passed; 0 failed; 0 ignored; 1 measured\n```\n\nHowever, the optimizer can still modify a testcase in an undesirable manner\neven when using either of the above.\n" } , LintCompletion { label : "windows_stdio" , description : "# `windows_stdio`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "allocator_api" , description : "# `allocator_api`\n\nThe tracking issue for this feature is [#32838]\n\n[#32838]: https://github.com/rust-lang/rust/issues/32838\n\n------------------------\n\nSometimes you want the memory for one collection to use a different\nallocator than the memory for another collection.

Rust supports using inline\nassembly to do this via the `asm!` macro.\n\n# Guide-level explanation\n[guide-level-explanation]: #guide-level-explanation\n\nRust provides support for inline assembly via the `asm!` macro.\nIt can be used to embed handwritten assembly in the assembly output generated by the compiler.\nGenerally this should not be necessary, but might be where the required performance or timing\ncannot be otherwise achieved. Accessing low level hardware primitives, e.g. in kernel code, may also demand this functionality.\n\n> **Note**: the examples here are given in x86/x86-64 assembly, but ARM, AArch64 and RISC-V are also supported.\n\n## Basic usage\n\nLet us start with the simplest possible example:\n\n```rust,allow_fail\n# #![feature(asm)]\nunsafe {\n asm!(\"nop\");\n}\n```\n\nThis will insert a NOP (no operation) instruction into the assembly generated by the compiler.\nNote that all `asm!` invocations have to be inside an `unsafe` block, as they could insert\narbitrary instructions and break various invariants. The instructions to be inserted are listed\nin the first argument of the `asm!` macro as a string literal.\n\n## Inputs and outputs\n\nNow inserting an instruction that does nothing is rather boring. Let us do something that\nactually acts on data:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet x: u64;\nunsafe {\n asm!(\"mov {}, 5\", out(reg) x);\n}\nassert_eq!(x, 5);\n```\n\nThis will write the value `5` into the `u64` variable `x`.\nYou can see that the string literal we use to specify instructions is actually a template string.\nIt is governed by the same rules as Rust [format strings][format-syntax].\nThe arguments that are inserted into the template however look a bit different then you may\nbe familiar with. First we need to specify if the variable is an input or an output of the\ninline assembly. In this case it is an output. We declared this by writing `out`.\nWe also need to specify in what kind of register the assembly expects the variable.\nIn this case we put it in an arbitrary general purpose register by specifying `reg`.\nThe compiler will choose an appropriate register to insert into\nthe template and will read the variable from there after the inline assembly finishes executing.\n\nLet us see another example that also uses an input:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet i: u64 = 3;\nlet o: u64;\nunsafe {\n asm!(\n \"mov {0}, {1}\",\n \"add {0}, {number}\",\n out(reg) o,\n in(reg) i,\n number = const 5,\n );\n}\nassert_eq!(o, 8);\n```\n\nThis will add `5` to the input in variable `i` and write the result to variable `o`.\nThe particular way this assembly does this is first copying the value from `i` to the output,\nand then adding `5` to it.\n\nThe example shows a few things:\n\nFirst, we can see that `asm!` allows multiple template string arguments; each\none is treated as a separate line of assembly code, as if they were all joined\ntogether with newlines between them. This makes it easy to format assembly\ncode.\n\nSecond, we can see that inputs are declared by writing `in` instead of `out`.\n\nThird, one of our operands has a type we haven't seen yet, `const`.\nThis tells the compiler to expand this argument to value directly inside the assembly template.\nThis is only possible for constants and literals.\n\nFourth, we can see that we can specify an argument number, or name as in any format string.\nFor inline assembly templates this is particularly useful as arguments are often used more than once.\nFor more complex inline assembly using this facility is generally recommended, as it improves\nreadability, and allows reordering instructions without changing the argument order.\n\nWe can further refine the above example to avoid the `mov` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut x: u64 = 3;\nunsafe {\n asm!(\"add {0}, {number}\", inout(reg) x, number = const 5);\n}\nassert_eq!(x, 8);\n```\n\nWe can see that `inout` is used to specify an argument that is both input and output.\nThis is different from specifying an input and output separately in that it is guaranteed to assign both to the same register.\n\nIt is also possible to specify different variables for the input and output parts of an `inout` operand:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet x: u64 = 3;\nlet y: u64;\nunsafe {\n asm!(\"add {0}, {number}\", inout(reg) x => y, number = const 5);\n}\nassert_eq!(y, 8);\n```\n\n## Late output operands\n\nThe Rust compiler is conservative with its allocation of operands. It is assumed that an `out`\ncan be written at any time, and can therefore not share its location with any other argument.\nHowever, to guarantee optimal performance it is important to use as few registers as possible,\nso they won't have to be saved and reloaded around the inline assembly block.\nTo achieve this Rust provides a `lateout` specifier. This can be used on any output that is\nwritten only after all inputs have been consumed.\nThere is also a `inlateout` variant of this specifier.\n\nHere is an example where `inlateout` *cannot* be used:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nlet c: u64 = 4;\nunsafe {\n asm!(\n \"add {0}, {1}\",\n \"add {0}, {2}\",\n inout(reg) a,\n in(reg) b,\n in(reg) c,\n );\n}\nassert_eq!(a, 12);\n```\n\nHere the compiler is free to allocate the same register for inputs `b` and `c` since it knows they have the same value. However it must allocate a separate register for `a` since it uses `inout` and not `inlateout`. If `inlateout` was used, then `a` and `c` could be allocated to the same register, in which case the first instruction to overwrite the value of `c` and cause the assembly code to produce the wrong result.\n\nHowever the following example can use `inlateout` since the output is only modified after all input registers have been read:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nunsafe {\n asm!(\"add {0}, {1}\", inlateout(reg) a, in(reg) b);\n}\nassert_eq!(a, 8);\n```\n\nAs you can see, this assembly fragment will still work correctly if `a` and `b` are assigned to the same register.\n\n## Explicit register operands\n\nSome instructions require that the operands be in a specific register.\nTherefore, Rust inline assembly provides some more specific constraint specifiers.\nWhile `reg` is generally available on any architecture, these are highly architecture specific. E.g. for x86 the general purpose registers `eax`, `ebx`, `ecx`, `edx`, `ebp`, `esi`, and `edi`\namong others can be addressed by their name.\n\n```rust,allow_fail,no_run\n# #![feature(asm)]\nlet cmd = 0xd1;\nunsafe {\n asm!(\"out 0x64, eax\", in(\"eax\") cmd);\n}\n```\n\nIn this example we call the `out` instruction to output the content of the `cmd` variable\nto port `0x64`. Since the `out` instruction only accepts `eax` (and its sub registers) as operand\nwe had to use the `eax` constraint specifier.\n\nNote that unlike other operand types, explicit register operands cannot be used in the template string: you can't use `{}` and should write the register name directly instead. Also, they must appear at the end of the operand list after all other operand types.\n\nConsider this example which uses the x86 `mul` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nfn mul(a: u64, b: u64) -> u128 {\n let lo: u64;\n let hi: u64;\n\n unsafe {\n asm!(\n // The x86 mul instruction takes rax as an implicit input and writes\n // the 128-bit result of the multiplication to rax:rdx.\n \"mul {}\",\n in(reg) a,\n inlateout(\"rax\") b => lo,\n lateout(\"rdx\") hi\n );\n }\n\n ((hi as u128) << 64) + lo as u128\n}\n```\n\nThis uses the `mul` instruction to multiply two 64-bit inputs with a 128-bit result.\nThe only explicit operand is a register, that we fill from the variable `a`.\nThe second operand is implicit, and must be the `rax` register, which we fill from the variable `b`.\nThe lower 64 bits of the result are stored in `rax` from which we fill the variable `lo`.\nThe higher 64 bits are stored in `rdx` from which we fill the variable `hi`.\n\n## Clobbered registers\n\nIn many cases inline assembly will modify state that is not needed as an output.\nUsually this is either because we have to use a scratch register in the assembly,\nor instructions modify state that we don't need to further examine.\nThis state is generally referred to as being \"clobbered\".\nWe need to tell the compiler about this since it may need to save and restore this state\naround the inline assembly block.\n\n```rust,allow_fail\n# #![feature(asm)]\nlet ebx: u32;\nlet ecx: u32;\n\nunsafe {\n asm!(\n \"cpuid\",\n // EAX 4 selects the \"Deterministic Cache Parameters\" CPUID leaf\n inout(\"eax\") 4 => _,\n // ECX 0 selects the L0 cache information.\n inout(\"ecx\") 0 => ecx,\n lateout(\"ebx\") ebx,\n lateout(\"edx\") _,\n );\n}\n\nprintln!(\n \"L1 Cache: {}\",\n ((ebx >> 22) + 1) * (((ebx >> 12) & 0x3ff) + 1) * ((ebx & 0xfff) + 1) * (ecx + 1)\n);\n```\n\nIn the example above we use the `cpuid` instruction to get the L1 cache size.\nThis instruction writes to `eax`, `ebx`, `ecx`, and `edx`, but for the cache size we only care about the contents of `ebx` and `ecx`.\n\nHowever we still need to tell the compiler that `eax` and `edx` have been modified so that it can save any values that were in these registers before the asm. This is done by declaring these as outputs but with `_` instead of a variable name, which indicates that the output value is to be discarded.\n\nThis can also be used with a general register class (e.g. `reg`) to obtain a scratch register for use inside the asm code:\n\n```rust,allow_fail\n# #![feature(asm)]\n// Multiply x by 6 using shifts and adds\nlet mut x: u64 = 4;\nunsafe {\n asm!(\n \"mov {tmp}, {x}\",\n \"shl {tmp}, 1\",\n \"shl {x}, 2\",\n \"add {x}, {tmp}\",\n x = inout(reg) x,\n tmp = out(reg) _,\n );\n}\nassert_eq!(x, 4 * 6);\n```\n\n## Symbol operands\n\nA special operand type, `sym`, allows you to use the symbol name of a `fn` or `static` in inline assembly code.\nThis allows you to call a function or access a global variable without needing to keep its address in a register.\n\n```rust,allow_fail\n# #![feature(asm)]\nextern \"C\" fn foo(arg: i32) {\n println!(\"arg = {}\", arg);\n}\n\nfn call_foo(arg: i32) {\n unsafe {\n asm!(\n \"call {}\",\n sym foo,\n // 1st argument in rdi, which is caller-saved\n inout(\"rdi\") arg => _,\n // All caller-saved registers must be marked as clobberred\n out(\"rax\") _, out(\"rcx\") _, out(\"rdx\") _, out(\"rsi\") _,\n out(\"r8\") _, out(\"r9\") _, out(\"r10\") _, out(\"r11\") _,\n out(\"xmm0\") _, out(\"xmm1\") _, out(\"xmm2\") _, out(\"xmm3\") _,\n out(\"xmm4\") _, out(\"xmm5\") _, out(\"xmm6\") _, out(\"xmm7\") _,\n out(\"xmm8\") _, out(\"xmm9\") _, out(\"xmm10\") _, out(\"xmm11\") _,\n out(\"xmm12\") _, out(\"xmm13\") _, out(\"xmm14\") _, out(\"xmm15\") _,\n )\n }\n}\n```\n\nNote that the `fn` or `static` item does not need to be public or `#[no_mangle]`:\nthe compiler will automatically insert the appropriate mangled symbol name into the assembly code.\n\n## Register template modifiers\n\nIn some cases, fine control is needed over the way a register name is formatted when inserted into the template string. This is needed when an architecture's assembly language has several names for the same register, each typically being a \"view\" over a subset of the register (e.g. the low 32 bits of a 64-bit register).\n\nBy default the compiler will always choose the name that refers to the full register size (e.g. `rax` on x86-64, `eax` on x86, etc).\n\nThis default can be overriden by using modifiers on the template string operands, just like you would with format strings:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut x: u16 = 0xab;\n\nunsafe {\n asm!(\"mov {0:h}, {0:l}\", inout(reg_abcd) x);\n}\n\nassert_eq!(x, 0xabab);\n```\n\nIn this example, we use the `reg_abcd` register class to restrict the register allocator to the 4 legacy x86 register (`ax`, `bx`, `cx`, `dx`) of which the first two bytes can be addressed independently.\n\nLet us assume that the register allocator has chosen to allocate `x` in the `ax` register.\nThe `h` modifier will emit the register name for the high byte of that register and the `l` modifier will emit the register name for the low byte. The asm code will therefore be expanded as `mov ah, al` which copies the low byte of the value into the high byte.\n\nIf you use a smaller data type (e.g. `u16`) with an operand and forget the use template modifiers, the compiler will emit a warning and suggest the correct modifier to use.\n\n## Options\n\nBy default, an inline assembly block is treated the same way as an external FFI function call with a custom calling convention: it may read/write memory, have observable side effects, etc. However in many cases, it is desirable to give the compiler more information about what the assembly code is actually doing so that it can optimize better.\n\nLet's take our previous example of an `add` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nunsafe {\n asm!(\n \"add {0}, {1}\",\n inlateout(reg) a, in(reg) b,\n options(pure, nomem, nostack),\n );\n}\nassert_eq!(a, 8);\n```\n\nOptions can be provided as an optional final argument to the `asm!` macro. We specified three options here:\n- `pure` means that the asm code has no observable side effects and that its output depends only on its inputs. This allows the compiler optimizer to call the inline asm fewer times or even eliminate it entirely.\n- `nomem` means that the asm code does not read or write to memory. By default the compiler will assume that inline assembly can read or write any memory address that is accessible to it (e.g. through a pointer passed as an operand, or a global).\n- `nostack` means that the asm code does not push any data onto the stack. This allows the compiler to use optimizations such as the stack red zone on x86-64 to avoid stack pointer adjustments.\n\nThese allow the compiler to better optimize code using `asm!`, for example by eliminating pure `asm!` blocks whose outputs are not needed.\n\nSee the reference for the full list of available options and their effects.\n\n# Reference-level explanation\n[reference-level-explanation]: #reference-level-explanation\n\nInline assembler is implemented as an unsafe macro `asm!()`.\nThe first argument to this macro is a template string literal used to build the final assembly.\nThe following arguments specify input and output operands.\nWhen required, options are specified as the final argument.\n\nThe following ABNF specifies the general syntax:\n\n```ignore\ndir_spec := \"in\" / \"out\" / \"lateout\" / \"inout\" / \"inlateout\"\nreg_spec := / \"\"\noperand_expr := expr / \"_\" / expr \"=>\" expr / expr \"=>\" \"_\"\nreg_operand := dir_spec \"(\" reg_spec \")\" operand_expr\noperand := reg_operand / \"const\" const_expr / \"sym\" path\noption := \"pure\" / \"nomem\" / \"readonly\" / \"preserves_flags\" / \"noreturn\" / \"att_syntax\"\noptions := \"options(\" option *[\",\" option] [\",\"] \")\"\nasm := \"asm!(\" format_string *(\",\" format_string) *(\",\" [ident \"=\"] operand) [\",\" options] [\",\"] \")\"\n```\n\nThe macro will initially be supported only on ARM, AArch64, Hexagon, x86, x86-64 and RISC-V targets. Support for more targets may be added in the future. The compiler will emit an error if `asm!` is used on an unsupported target.\n\n[format-syntax]: https://doc.rust-lang.org/std/fmt/#syntax\n\n## Template string arguments\n\nThe assembler template uses the same syntax as [format strings][format-syntax] (i.e. placeholders are specified by curly braces). The corresponding arguments are accessed in order, by index, or by name. However, implicit named arguments (introduced by [RFC #2795][rfc-2795]) are not supported.\n\nAn `asm!` invocation may have one or more template string arguments; an `asm!` with multiple template string arguments is treated as if all the strings were concatenated with a `\\n` between them. The expected usage is for each template string argument to correspond to a line of assembly code. All template string arguments must appear before any other arguments.\n\nAs with format strings, named arguments must appear after positional arguments. Explicit register operands must appear at the end of the operand list, after named arguments if any.\n\nExplicit register operands cannot be used by placeholders in the template string. All other named and positional operands must appear at least once in the template string, otherwise a compiler error is generated.\n\nThe exact assembly code syntax is target-specific and opaque to the compiler except for the way operands are substituted into the template string to form the code passed to the assembler.\n\nThe 5 targets specified in this RFC (x86, ARM, AArch64, RISC-V, Hexagon) all use the assembly code syntax of the GNU assembler (GAS). On x86, the `.intel_syntax noprefix` mode of GAS is used by default. On ARM, the `.syntax unified` mode is used. These targets impose an additional restriction on the assembly code: any assembler state (e.g. the current section which can be changed with `.section`) must be restored to its original value at the end of the asm string. Assembly code that does not conform to the GAS syntax will result in assembler-specific behavior.\n\n[rfc-2795]: https://github.com/rust-lang/rfcs/pull/2795\n\n## Operand type\n\nSeveral types of operands are supported:\n\n* `in() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain the value of `` at the start of the asm code.\n - The allocated register must contain the same value at the end of the asm code (except if a `lateout` is allocated to the same register).\n* `out() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain an undefined value at the start of the asm code.\n - `` must be a (possibly uninitialized) place expression, to which the contents of the allocated register is written to at the end of the asm code.\n - An underscore (`_`) may be specified instead of an expression, which will cause the contents of the register to be discarded at the end of the asm code (effectively acting as a clobber).\n* `lateout() `\n - Identical to `out` except that the register allocator can reuse a register allocated to an `in`.\n - You should only write to the register after all inputs are read, otherwise you may clobber an input.\n* `inout() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain the value of `` at the start of the asm code.\n - `` must be a mutable initialized place expression, to which the contents of the allocated register is written to at the end of the asm code.\n* `inout() => `\n - Same as `inout` except that the initial value of the register is taken from the value of ``.\n - `` must be a (possibly uninitialized) place expression, to which the contents of the allocated register is written to at the end of the asm code.\n - An underscore (`_`) may be specified instead of an expression for ``, which will cause the contents of the register to be discarded at the end of the asm code (effectively acting as a clobber).\n - `` and `` may have different types.\n* `inlateout() ` / `inlateout() => `\n - Identical to `inout` except that the register allocator can reuse a register allocated to an `in` (this can happen if the compiler knows the `in` has the same initial value as the `inlateout`).\n - You should only write to the register after all inputs are read, otherwise you may clobber an input.\n* `const `\n - `` must be an integer or floating-point constant expression.\n - The value of the expression is formatted as a string and substituted directly into the asm template string.\n* `sym `\n - `` must refer to a `fn` or `static`.\n - A mangled symbol name referring to the item is substituted into the asm template string.\n - The substituted string does not include any modifiers (e.g. GOT, PLT, relocations, etc).\n - `` is allowed to point to a `#[thread_local]` static, in which case the asm code can combine the symbol with relocations (e.g. `@plt`, `@TPOFF`) to read from thread-local data.\n\nOperand expressions are evaluated from left to right, just like function call arguments. After the `asm!` has executed, outputs are written to in left to right order. This is significant if two outputs point to the same place: that place will contain the value of the rightmost output.\n\n## Register operands\n\nInput and output operands can be specified either as an explicit register or as a register class from which the register allocator can select a register. Explicit registers are specified as string literals (e.g. `\"eax\"`) while register classes are specified as identifiers (e.g. `reg`). Using string literals for register names enables support for architectures that use special characters in register names, such as MIPS (`$0`, `$1`, etc).\n\nNote that explicit registers treat register aliases (e.g. `r14` vs `lr` on ARM) and smaller views of a register (e.g. `eax` vs `rax`) as equivalent to the base register. It is a compile-time error to use the same explicit register for two input operands or two output operands. Additionally, it is also a compile-time error to use overlapping registers (e.g. ARM VFP) in input operands or in output operands.\n\nOnly the following types are allowed as operands for inline assembly:\n- Integers (signed and unsigned)\n- Floating-point numbers\n- Pointers (thin only)\n- Function pointers\n- SIMD vectors (structs defined with `#[repr(simd)]` and which implement `Copy`). This includes architecture-specific vector types defined in `std::arch` such as `__m128` (x86) or `int8x16_t` (ARM).\n\nHere is the list of currently supported register classes:\n\n| Architecture | Register class | Registers | LLVM constraint code |\n| ------------ | -------------- | --------- | -------------------- |\n| x86 | `reg` | `ax`, `bx`, `cx`, `dx`, `si`, `di`, `r[8-15]` (x86-64 only) | `r` |\n| x86 | `reg_abcd` | `ax`, `bx`, `cx`, `dx` | `Q` |\n| x86-32 | `reg_byte` | `al`, `bl`, `cl`, `dl`, `ah`, `bh`, `ch`, `dh` | `q` |\n| x86-64 | `reg_byte` | `al`, `bl`, `cl`, `dl`, `sil`, `dil`, `r[8-15]b`, `ah`\\*, `bh`\\*, `ch`\\*, `dh`\\* | `q` |\n| x86 | `xmm_reg` | `xmm[0-7]` (x86) `xmm[0-15]` (x86-64) | `x` |\n| x86 | `ymm_reg` | `ymm[0-7]` (x86) `ymm[0-15]` (x86-64) | `x` |\n| x86 | `zmm_reg` | `zmm[0-7]` (x86) `zmm[0-31]` (x86-64) | `v` |\n| x86 | `kreg` | `k[1-7]` | `Yk` |\n| AArch64 | `reg` | `x[0-28]`, `x30` | `r` |\n| AArch64 | `vreg` | `v[0-31]` | `w` |\n| AArch64 | `vreg_low16` | `v[0-15]` | `x` |\n| ARM | `reg` | `r[0-5]` `r7`\\*, `r[8-10]`, `r11`\\*, `r12`, `r14` | `r` |\n| ARM (Thumb) | `reg_thumb` | `r[0-r7]` | `l` |\n| ARM (ARM) | `reg_thumb` | `r[0-r10]`, `r12`, `r14` | `l` |\n| ARM | `sreg` | `s[0-31]` | `t` |\n| ARM | `sreg_low16` | `s[0-15]` | `x` |\n| ARM | `dreg` | `d[0-31]` | `w` |\n| ARM | `dreg_low16` | `d[0-15]` | `t` |\n| ARM | `dreg_low8` | `d[0-8]` | `x` |\n| ARM | `qreg` | `q[0-15]` | `w` |\n| ARM | `qreg_low8` | `q[0-7]` | `t` |\n| ARM | `qreg_low4` | `q[0-3]` | `x` |\n| NVPTX | `reg16` | None\\* | `h` |\n| NVPTX | `reg32` | None\\* | `r` |\n| NVPTX | `reg64` | None\\* | `l` |\n| RISC-V | `reg` | `x1`, `x[5-7]`, `x[9-15]`, `x[16-31]` (non-RV32E) | `r` |\n| RISC-V | `freg` | `f[0-31]` | `f` |\n| Hexagon | `reg` | `r[0-28]` | `r` |\n\n> **Note**: On x86 we treat `reg_byte` differently from `reg` because the compiler can allocate `al` and `ah` separately whereas `reg` reserves the whole register.\n>\n> Note #2: On x86-64 the high byte registers (e.g. `ah`) are only available when used as an explicit register. Specifying the `reg_byte` register class for an operand will always allocate a low byte register.\n>\n> Note #3: NVPTX doesn't have a fixed register set, so named registers are not supported.\n>\n> Note #4: On ARM the frame pointer is either `r7` or `r11` depending on the platform.\n\nAdditional register classes may be added in the future based on demand (e.g. MMX, x87, etc).\n\nEach register class has constraints on which value types they can be used with. This is necessary because the way a value is loaded into a register depends on its type. For example, on big-endian systems, loading a `i32x4` and a `i8x16` into a SIMD register may result in different register contents even if the byte-wise memory representation of both values is identical. The availability of supported types for a particular register class may depend on what target features are currently enabled.\n\n| Architecture | Register class | Target feature | Allowed types |\n| ------------ | -------------- | -------------- | ------------- |\n| x86-32 | `reg` | None | `i16`, `i32`, `f32` |\n| x86-64 | `reg` | None | `i16`, `i32`, `f32`, `i64`, `f64` |\n| x86 | `reg_byte` | None | `i8` |\n| x86 | `xmm_reg` | `sse` | `i32`, `f32`, `i64`, `f64`,

The only exception is the `freg` register class on RISC-V where `f32` values are NaN-boxed in a `f64` as required by the RISC-V architecture.\n\nWhen separate input and output expressions are specified for an `inout` operand, both expressions must have the same type. The only exception is if both operands are pointers or integers, in which case they are only required to have the same size. This restriction exists because the register allocators in LLVM and GCC sometimes cannot handle tied operands with different types.\n\n## Register names\n\nSome registers have multiple names.

The frame pointer cannot be used as an input or output. |\n| ARM | `r6` | `r6` is used internally by LLVM as a base pointer and therefore cannot be used as an input or output. |\n| x86 | `k0` | This is a constant zero register which can't be modified. |\n| x86 | `ip` | This is the program counter, not a real register. |\n| x86 | `mm[0-7]` | MMX registers are not currently supported (but may be in the future). |\n| x86 | `st([0-7])` | x87 registers are not currently supported (but may be in the future). |\n| AArch64 | `xzr` | This is a constant zero register which can't be modified. |\n| ARM | `pc` | This is the program counter, not a real register. |\n| RISC-V | `x0` | This is a constant zero register which can't be modified. |\n| RISC-V | `gp`, `tp` | These registers are reserved and cannot be used as inputs or outputs. |\n| Hexagon | `lr` | This is the link register which cannot be used as an input or output. |\n\n## Template modifiers\n\nThe placeholders can be augmented by modifiers which are specified after the `:` in the curly braces. These modifiers do not affect register allocation, but change the way operands are formatted when inserted into the template string. Only one modifier is allowed per template placeholder.\n\nThe supported modifiers are a subset of LLVM's (and GCC's) [asm template argument modifiers][llvm-argmod], but do not use the same letter codes.\n\n| Architecture | Register class | Modifier | Example output | LLVM modifier |\n| ------------ | -------------- | -------- | -------------- | ------------- |\n| x86-32 | `reg` | None | `eax` | `k` |\n| x86-64 | `reg` | None | `rax` | `q` |\n| x86-32 | `reg_abcd` | `l` | `al` | `b` |\n| x86-64 | `reg` | `l` | `al` | `b` |\n| x86 | `reg_abcd` | `h` | `ah` | `h` |\n| x86 | `reg` | `x` | `ax` | `w` |\n| x86 | `reg` | `e` | `eax` | `k` |\n| x86-64 | `reg` | `r` | `rax` | `q` |\n| x86 | `reg_byte` | None | `al` / `ah` | None |\n| x86 | `xmm_reg` | None | `xmm0` | `x` |\n| x86 | `ymm_reg` | None | `ymm0` | `t` |\n| x86 | `zmm_reg` | None | `zmm0` | `g` |\n| x86 | `*mm_reg` | `x` | `xmm0` | `x` |\n| x86 | `*mm_reg` | `y` | `ymm0` | `t` |\n| x86 | `*mm_reg` | `z` | `zmm0` | `g` |\n| x86 | `kreg` | None | `k1` | None |\n| AArch64 | `reg` | None | `x0` | `x` |\n| AArch64 | `reg` | `w` | `w0` | `w` |\n| AArch64 | `reg` | `x` | `x0` | `x` |\n| AArch64 | `vreg` | None | `v0` | None |\n| AArch64 | `vreg` | `v` | `v0` | None |\n| AArch64 | `vreg` | `b` | `b0` | `b` |\n| AArch64 | `vreg` | `h` | `h0` | `h` |\n| AArch64 | `vreg` | `s` | `s0` | `s` |\n| AArch64 | `vreg` | `d` | `d0` | `d` |\n| AArch64 | `vreg` | `q` | `q0` | `q` |\n| ARM | `reg` | None | `r0` | None |\n| ARM | `sreg` | None | `s0` | None |\n| ARM | `dreg` | None | `d0` | `P` |\n| ARM | `qreg` | None | `q0` | `q` |\n| ARM | `qreg` | `e` / `f` | `d0` / `d1` | `e` / `f` |\n| NVPTX | `reg16` | None | `rs0` | None |\n| NVPTX | `reg32` | None | `r0` | None |\n| NVPTX | `reg64` | None | `rd0` | None |\n| RISC-V | `reg` | None | `x1` | None |\n| RISC-V | `freg` | None | `f0` | None |\n| Hexagon | `reg` | None | `r0` | None |\n\n> Notes:\n> - on ARM `e` / `f`: this prints the low or high doubleword register name of a NEON quad (128-bit) register.\n> - on x86: our behavior for `reg` with no modifiers differs from what GCC does. GCC will infer the modifier based on the operand value type, while we default to the full register size.\n> - on x86 `xmm_reg`: the `x`, `t` and `g` LLVM modifiers are not yet implemented in LLVM (they are supported by GCC only), but this should be a simple change.\n\nAs stated in the previous section, passing an input value smaller than the register width will result in the upper bits of the register containing undefined values. This is not a problem if the inline asm only accesses the lower bits of the register, which can be done by using a template modifier to use a subregister name in the asm code (e.g. `ax` instead of `rax`). Since this an easy pitfall, the compiler will suggest a template modifier to use where appropriate given the input type. If all references to an operand already have modifiers then the warning is suppressed for that operand.\n\n[llvm-argmod]: http://llvm.org/docs/LangRef.html#asm-template-argument-modifiers\n\n## Options\n\nFlags are used to further influence the behavior of the inline assembly block.\nCurrently the following options are defined:\n- `pure`: The `asm` block has no side effects, and its outputs depend only on its direct inputs (i.e. the values themselves, not what they point to) or values read from memory (unless the `nomem` options is also set). This allows the compiler to execute the `asm` block fewer times than specified in the program (e.g. by hoisting it out of a loop) or even eliminate it entirely if the outputs are not used.\n- `nomem`: The `asm` blocks does not read or write to any memory. This allows the compiler to cache the values of modified global variables in registers across the `asm` block since it knows that they are not read or written to by the `asm`.\n- `readonly`: The `asm` block does not write to any memory. This allows the compiler to cache the values of unmodified global variables in registers across the `asm` block since it knows that they are not written to by the `asm`.\n- `preserves_flags`: The `asm` block does not modify the flags register (defined in the rules below). This allows the compiler to avoid recomputing the condition flags after the `asm` block.\n- `noreturn`: The `asm` block never returns, and its return type is defined as `!` (never). Behavior is undefined if execution falls through past the end of the asm code. A `noreturn` asm block behaves just like a function which doesn't return; notably, local variables in scope are not dropped before it is invoked.\n- `nostack`: The `asm` block does not push data to the stack, or write to the stack red-zone (if supported by the target). If this option is *not* used then the stack pointer is guaranteed to be suitably aligned (according to the target ABI) for a function call.\n- `att_syntax`: This option is only valid on x86, and causes the assembler to use the `.att_syntax prefix` mode of the GNU assembler. Register operands are substituted in with a leading `%`.\n\nThe compiler performs some additional checks on options:\n- The `nomem` and `readonly` options are mutually exclusive: it is a compile-time error to specify both.\n- The `pure` option must be combined with either the `nomem` or `readonly` options, otherwise a compile-time error is emitted.\n- It is a compile-time error to specify `pure` on an asm block with no outputs or only discarded outputs (`_`).\n- It is a compile-time error to specify `noreturn` on an asm block with outputs.\n\n## Rules for inline assembly\n\n- Any registers not specified as inputs will contain an undefined value on entry to the asm block.\n - An \"undefined value\" in the context of inline assembly means that the register can (non-deterministically) have any one of the possible values allowed by the architecture. Notably it is not the same as an LLVM `undef` which can have a different value every time you read it (since such a concept does not exist in assembly code).\n- Any registers not specified as outputs must have the same value upon exiting the asm block as they had on entry, otherwise behavior is undefined.\n - This only applies to registers which can be specified as an input or output. Other registers follow target-specific rules.\n - Note that a `lateout` may be allocated to the same register as an `in`, in which case this rule does not apply. Code should not rely on this however since it depends on the results of register allocation.\n- Behavior is undefined if execution unwinds out of an asm block.\n - This also applies if the assembly code calls a function which then unwinds.\n- The set of memory locations that assembly code is allowed the read and write are the same as those allowed for an FFI function.\n - Refer to the unsafe code guidelines for the exact rules.\n - If the `readonly` option is set, then only memory reads are allowed.\n - If the `nomem` option is set then no reads or writes to memory are allowed.\n - These rules do not apply to memory which is private to the asm code, such as stack space allocated within the asm block.\n- The compiler cannot assume that the instructions in the asm are the ones that will actually end up executed.\n - This effectively means that the compiler must treat the `asm!` as a black box and only take the interface specification into account, not the instructions themselves.\n - Runtime code patching is allowed, via target-specific mechanisms (outside the scope of this RFC).\n- Unless the `nostack` option is set, asm code is allowed to use stack space below the stack pointer.\n - On entry to the asm block the stack pointer is guaranteed to be suitably aligned (according to the target ABI) for a function call.\n - You are responsible for making sure you don't overflow the stack (e.g. use stack probing to ensure you hit a guard page).\n - You should adjust the stack pointer when allocating stack memory as required by the target ABI.\n - The stack pointer must be restored to its original value before leaving the asm block.\n- If the `noreturn` option is set then behavior is undefined if execution falls through to the end of the asm block.\n- If the `pure` option is set then behavior is undefined if the `asm` has side-effects other than its direct outputs. Behavior is also undefined if two executions of the `asm` code with the same inputs result in different outputs.\n - When used with the `nomem` option, \"inputs\" are just the direct inputs of the `asm!`.\n - When used with the `readonly` option, \"inputs\" comprise the direct inputs of the `asm!` and any memory that the `asm!` block is allowed to read.\n- These flags registers must be restored upon exiting the asm block if the `preserves_flags` option is set:\n - x86\n - Status flags in `EFLAGS` (CF, PF, AF, ZF, SF, OF).\n - Floating-point status word (all).\n - Floating-point exception flags in `MXCSR` (PE, UE, OE, ZE, DE, IE).\n - ARM\n - Condition flags in `CPSR` (N, Z, C, V)\n - Saturation flag in `CPSR` (Q)\n - Greater than or equal flags in `CPSR` (GE).\n - Condition flags in `FPSCR` (N, Z, C, V)\n - Saturation flag in `FPSCR` (QC)\n - Floating-point exception flags in `FPSCR` (IDC, IXC, UFC, OFC, DZC, IOC).\n - AArch64\n - Condition flags (`NZCV` register).\n - Floating-point status (`FPSR` register).\n - RISC-V\n - Floating-point exception flags in `fcsr` (`fflags`).\n- On x86, the direction flag (DF in `EFLAGS`) is clear on entry to an asm block and must be clear on exit.\n - Behavior is undefined if the direction flag is set on exiting an asm block.\n- The requirement of restoring the stack pointer and non-output registers to their original value only applies when exiting an `asm!` block.\n - This means that `asm!` blocks that never return (even if not marked `noreturn`) don't need to preserve these registers.\n - When returning to a different `asm!` block than you entered (e.g. for context switching), these registers must contain the value they had upon entering the `asm!` block that you are *exiting*.\n - You cannot exit an `asm!` block that has not been entered. Neither can you exit an `asm!` block that has already been exited.\n - You are responsible for switching any target-specific state (e.g. thread-local storage, stack bounds).\n - The set of memory locations that you may access is the intersection of those allowed by the `asm!` blocks you entered and exited.\n- You cannot assume that an `asm!` block will appear exactly once in the output binary. The compiler is allowed to instantiate multiple copies of the `asm!` block, for example when the function containing it is inlined in multiple places.\n - As a consequence, you should only use [local labels] inside inline assembly code. Defining symbols in assembly code may lead to assembler and/or linker errors due to duplicate symbol definitions.\n\n> **Note**: As a general rule, the flags covered by `preserves_flags` are those which are *not* preserved when performing a function call.\n\n[local labels]: https://sourceware.org/binutils/docs/as/Symbol-Names.html#Local-Labels\n" } , LintCompletion { label : "is_sorted" ,

This is useful for very low level programming, where\nwhich register you use is important:\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# unsafe fn read_byte_in(port: u16) -> u8 {\nlet result: u8;\nllvm_asm!(\"in %dx, %al\" : \"={al}\"(result) : \"{dx}\"(port));\nresult\n# }\n```\n\n## Clobbers\n\nSome instructions modify registers which might otherwise have held\ndifferent values so we use the clobbers list to indicate to the\ncompiler not to assume any values loaded into those registers will\nstay valid.\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# fn main() { unsafe {\n// Put the value 0x200 in eax:\nllvm_asm!(\"mov $$0x200, %eax\" : /* no outputs */ : /* no inputs */ : \"eax\");\n# } }\n# #[cfg(not(any(target_arch = \"x86\", target_arch = \"x86_64\")))]\n# fn main() {}\n```\n\nInput and output registers need not be listed since that information\nis already communicated by the given constraints. Otherwise, any other\nregisters used either implicitly or explicitly should be listed.\n\nIf the assembly changes the condition code register `cc` should be\nspecified as one of the clobbers. Similarly, if the assembly modifies\nmemory, `memory` should also be specified.\n\n## Options\n\nThe last section, `options` is specific to Rust. The format is comma\nseparated literal strings (i.e. `:\"foo\", \"bar\", \"baz\"`). It's used to\nspecify some extra info about the inline assembly:\n\nCurrent valid options are:\n\n1. *volatile* - specifying this is analogous to\n `__asm__ __volatile__ (...)` in gcc/clang.\n2. *alignstack* - certain instructions expect the stack to be\n aligned a certain way (i.e. SSE) and specifying this indicates to\n the compiler to insert its usual stack alignment code\n3. *intel* - use intel syntax instead of the default AT&T.\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# fn main() {\nlet result: i32;\nunsafe {\n llvm_asm!(\"mov eax, 2\" : \"={eax}\"(result) : : : \"intel\")\n}\nprintln!(\"eax is currently {}\", result);\n# }\n# #[cfg(not(any(target_arch = \"x86\", target_arch = \"x86_64\")))]\n# fn main() {}\n```\n\n## More Information\n\nThe current implementation of the `llvm_asm!` macro is a direct binding to [LLVM's\ninline assembler expressions][llvm-docs], so be sure to check out [their\ndocumentation as well][llvm-docs] for more information about clobbers,\nconstraints, etc.\n\n[llvm-docs]: http://llvm.org/docs/LangRef.html#inline-assembler-expressions\n\nIf you need more power and don't mind losing some of the niceties of\n`llvm_asm!`, check out [global_asm](global-asm.md).\n" } ] ;

You can achieve the\nsame effect as the `link_args` attribute with the `-C link-args` argument to\n`rustc`.\n\nIt is highly recommended to *not* use this attribute, and rather use the more\nformal `#[link(...)]` attribute on `extern` blocks instead.\n" } , LintCompletion { label : "cfg_version" , description : "# `cfg_version`\n\nThe tracking issue for this feature is: [#64796]\n\n[#64796]: https://github.com/rust-lang/rust/issues/64796\n\n------------------------\n\nThe `cfg_version` feature makes it possible to execute different code\ndepending on the compiler version.\n\n## Examples\n\n```rust\n#![feature(cfg_version)]\n\n#[cfg(version(\"1.42\"))]\nfn a() {\n // ...\n}\n\n#[cfg(not(version(\"1.42\")))]\nfn a() {\n // ...\n}\n\nfn b() {\n if cfg!(version(\"1.42\")) {\n // ...\n } else {\n // ...\n }\n}\n```\n" } , LintCompletion { label : "ffi_const" , description : "# `ffi_const`\n\nThe `#[ffi_const]` attribute applies clang's `const` attribute to foreign\nfunctions declarations.\n\nThat is, `#[ffi_const]` functions shall have no effects except for its return\nvalue, which can only depend on the values of the function parameters, and is\nnot affected by changes to the observable state of the program.\n\nApplying the `#[ffi_const]` attribute to a function that violates these\nrequirements is undefined behaviour.\n\nThis attribute enables Rust to perform common optimizations, like sub-expression\nelimination, and it can avoid emitting some calls in repeated invocations of the\nfunction with the same argument values regardless of other operations being\nperformed in between these functions calls (as opposed to `#[ffi_pure]`\nfunctions).\n\n## Pitfalls\n\nA `#[ffi_const]` function can only read global memory that would not affect\nits return value for the whole execution of the program (e.g. immutable global\nmemory). `#[ffi_const]` functions are referentially-transparent and therefore\nmore strict than `#[ffi_pure]` functions.\n\nA common pitfall involves applying the `#[ffi_const]` attribute to a\nfunction that reads memory through pointer arguments which do not necessarily\npoint to immutable global memory.\n\nA `#[ffi_const]` function that returns unit has no effect on the abstract\nmachine's state, and a `#[ffi_const]` function cannot be `#[ffi_pure]`.\n\nA `#[ffi_const]` function must not diverge, neither via a side effect (e.g. a\ncall to `abort`) nor by infinite loops.\n\nWhen translating C headers to Rust FFI, it is worth verifying for which targets\nthe `const` attribute is enabled in those headers, and using the appropriate\n`cfg` macros in the Rust side to match those definitions.

A generator is a \"resumable function\" that syntactically\nresembles a closure but compiles to much different semantics in the compiler\nitself. The primary feature of a generator is that it can be suspended during\nexecution to be resumed at a later date. Generators use the `yield` keyword to\n\"return\", and then the caller can `resume` a generator to resume execution just\nafter the `yield` keyword.\n\nGenerators are an extra-unstable feature in the compiler right now. Added in\n[RFC 2033] they're mostly intended right now as a information/constraint\ngathering phase. The intent is that experimentation can happen on the nightly\ncompiler before actual stabilization. A further RFC will be required to\nstabilize generators/coroutines and will likely contain at least a few small\ntweaks to the overall design.\n\n[RFC 2033]: https://github.com/rust-lang/rfcs/pull/2033\n\nA syntactical example of a generator is:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::{Generator, GeneratorState};\nuse std::pin::Pin;\n\nfn main() {\n let mut generator = || {\n yield 1;\n return \"foo\"\n };\n\n match Pin::new(&mut generator).resume(()) {\n GeneratorState::Yielded(1) => {}\n _ => panic!(\"unexpected value from resume\"),\n }\n match Pin::new(&mut generator).resume(()) {\n GeneratorState::Complete(\"foo\") => {}\n _ => panic!(\"unexpected value from resume\"),\n }\n}\n```\n\nGenerators are closure-like literals which can contain a `yield` statement. The\n`yield` statement takes an optional expression of a value to yield out of the\ngenerator. All generator literals implement the `Generator` trait in the\n`std::ops` module. The `Generator` trait has one main method, `resume`, which\nresumes execution of the generator at the previous suspension point.\n\nAn example of the control flow of generators is that the following example\nprints all numbers in order:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::Generator;\nuse std::pin::Pin;\n\nfn main() {\n let mut generator = || {\n println!(\"2\");\n yield;\n println!(\"4\");\n };\n\n println!(\"1\");\n Pin::new(&mut generator).resume(());\n println!(\"3\");\n Pin::new(&mut generator).resume(());\n println!(\"5\");\n}\n```\n\nAt this time the main intended use case of generators is an implementation\nprimitive for async/await syntax, but generators will likely be extended to\nergonomic implementations of iterators and other primitives in the future.\nFeedback on the design and usage is always appreciated!\n\n### The `Generator` trait\n\nThe `Generator` trait in `std::ops` currently looks like:\n\n```rust\n# #![feature(arbitrary_self_types, generator_trait)]\n# use std::ops::GeneratorState;\n# use std::pin::Pin;\n\npub trait Generator {\n type Yield;\n type Return;\n fn resume(self: Pin<&mut Self>, resume: R) -> GeneratorState;\n}\n```\n\nThe `Generator::Yield` type is the type of values that can be yielded with the\n`yield` statement. The `Generator::Return` type is the returned type of the\ngenerator. This is typically the last expression in a generator's definition or\nany value passed to `return` in a generator. The `resume` function is the entry\npoint for executing the `Generator` itself.\n\nThe return value of `resume`, `GeneratorState`, looks like:\n\n```rust\npub enum GeneratorState {\n Yielded(Y),\n Complete(R),\n}\n```\n\nThe `Yielded` variant indicates that the generator can later be resumed. This\ncorresponds to a `yield` point in a generator. The `Complete` variant indicates\nthat the generator is complete and cannot be resumed again. Calling `resume`\nafter a generator has returned `Complete` will likely result in a panic of the\nprogram.\n\n### Closure-like semantics\n\nThe closure-like syntax for generators alludes to the fact that they also have\nclosure-like semantics. Namely:\n\n* When created, a generator executes no code. A closure literal does not\n actually execute any of the closure's code on construction, and similarly a\n generator literal does not execute any code inside the generator when\n constructed.\n\n* Generators can capture outer variables by reference or by move, and this can\n be tweaked with the `move` keyword at the beginning of the closure. Like\n closures all generators will have an implicit environment which is inferred by\n the compiler. Outer variables can be moved into a generator for use as the\n generator progresses.\n\n* Generator literals produce a value with a unique type which implements the\n `std::ops::Generator` trait. This allows actual execution of the generator\n through the `Generator::resume` method as well as also naming it in return\n types and such.\n\n* Traits like `Send` and `Sync` are automatically implemented for a `Generator`\n depending on the captured variables of the environment. Unlike closures,\n generators also depend on variables live across suspension points. This means\n that although the ambient environment may be `Send` or `Sync`, the generator\n itself may not be due to internal variables live across `yield` points being\n not-`Send` or not-`Sync`. Note that generators do\n not implement traits like `Copy` or `Clone` automatically.\n\n* Whenever a generator is dropped it will drop all captured environment\n variables.\n\n### Generators as state machines\n\nIn the compiler, generators are currently compiled as state machines. Each\n`yield` expression will correspond to a different state that stores all live\nvariables over that suspension point. Resumption of a generator will dispatch on\nthe current state and then execute internally until a `yield` is reached, at\nwhich point all state is saved off in the generator and a value is returned.\n\nLet's take a look at an example to see what's going on here:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::Generator;\nuse std::pin::Pin;\n\nfn main() {\n let ret = \"foo\";\n let mut generator = move || {\n yield 1;\n return ret\n };\n\n Pin::new(&mut generator).resume(());\n Pin::new(&mut generator).resume(());\n}\n```\n\nThis generator literal will compile down to something similar to:\n\n```rust\n#![feature(arbitrary_self_types, generators, generator_trait)]\n\nuse std::ops::{Generator, GeneratorState};\nuse std::pin::Pin;\n\nfn main() {\n let ret = \"foo\";\n let mut generator = {\n enum __Generator {\n Start(&'static str),\n Yield1(&'static str),\n Done,\n }\n\n impl Generator for __Generator {\n type Yield = i32;\n type Return = &'static str;\n\n fn resume(mut self: Pin<&mut Self>, resume: ()) -> GeneratorState {\n use std::mem;\n match mem::replace(&mut *self, __Generator::Done) {\n __Generator::Start(s) => {\n *self = __Generator::Yield1(s);\n GeneratorState::Yielded(1)\n }\n\n __Generator::Yield1(s) => {\n *self = __Generator::Done;\n GeneratorState::Complete(s)\n }\n\n __Generator::Done => {\n panic!(\"generator resumed after completion\")\n }\n }\n }\n }\n\n __Generator::Start(ret)\n };\n\n Pin::new(&mut generator).resume(());\n Pin::new(&mut generator).resume(());\n}\n```\n\nNotably here we can see that the compiler is generating a fresh type,\n`__Generator` in this case. This type has a number of states (represented here\nas an `enum`) corresponding to each of the conceptual states of the generator.\nAt the beginning we're closing over our outer variable `foo` and then that\nvariable is also live over the `yield` point, so it's stored in both states.\n\nWhen the generator starts it'll immediately yield 1, but it saves off its state\njust before it does so indicating that it has reached the yield point. Upon\nresuming again we'll execute the `return ret` which returns the `Complete`\nstate.\n\nHere we can also note that the `Done` state, if resumed, panics immediately as\nit's invalid to resume a completed generator. It's also worth noting that this\nis just a rough desugaring, not a normative specification for what the compiler\ndoes.\n" } , LintCompletion { label : "marker_trait_attr" , description : "# `marker_trait_attr`\n\nThe tracking issue for this feature is: [#29864]\n\n[#29864]: https://github.com/rust-lang/rust/issues/29864\n\n------------------------\n\nNormally, Rust keeps you from adding trait implementations that could\noverlap with each other, as it would be ambiguous which to use.

In the syntax, `n` isn't necessarily a constant expression. The array is dynamically allocated on the stack and has the type of `[T]`, instead of `[T; n]`.\n\n```rust,ignore\n#![feature(unsized_locals)]\n\nfn mergesort(a: &mut [T]) {\n let mut tmp = [T; dyn a.len()];\n // ...\n}\n\nfn main() {\n let mut a = [3, 1, 5, 6];\n mergesort(&mut a);\n assert_eq!(a, [1, 3, 5, 6]);\n}\n```\n\nVLAs are not implemented yet. The syntax isn't final, either. We may need an alternative syntax for Rust 2015 because, in Rust 2015, expressions like `[e; dyn(1)]` would be ambiguous. One possible alternative proposed in the RFC is `[e; n]`: if `n` captures one or more local variables, then it is considered as `[e; dyn n]`.\n\n## Advisory on stack usage\n\nIt's advised not to casually use the `#![feature(unsized_locals)]` feature. Typical use-cases are:\n\n- When you need a by-value trait objects.\n- When you really need a fast allocation of small temporary arrays.\n\nAnother pitfall is repetitive allocation and temporaries. Currently the compiler simply extends the stack frame every time it encounters an unsized assignment. So for example, the code\n\n```rust\n#![feature(unsized_locals)]\n\nfn main() {\n let x: Box<[i32]> = Box::new([1, 2, 3, 4, 5]);\n let _x = {{{{{{{{{{*x}}}}}}}}}};\n}\n```\n\nand the code\n\n```rust\n#![feature(unsized_locals)]\n\nfn main() {\n for _ in 0..10 {\n let x: Box<[i32]> = Box::new([1, 2, 3, 4, 5]);\n let _x = *x;\n }\n}\n```\n\nwill unnecessarily extend the stack frame.\n" } , LintCompletion { label : "or_patterns" , description : "# `or_patterns`\n\nThe tracking issue for this feature is: [#54883]\n\n[#54883]: https://github.com/rust-lang/rust/issues/54883\n\n------------------------\n\nThe `or_pattern` language feature allows `|` to be arbitrarily nested within\na pattern, for example, `Some(A(0) | B(1 | 2))` becomes a valid pattern.\n\n## Examples\n\n```rust,ignore\n#![feature(or_patterns)]\n\npub enum Foo {\n Bar,\n Baz,\n Quux,\n}\n\npub fn example(maybe_foo: Option) {\n match maybe_foo {\n Some(Foo::Bar | Foo::Baz) => {\n println!(\"The value contained `Bar` or `Baz`\");\n }\n Some(_) => {\n println!(\"The value did not contain `Bar` or `Baz`\");\n }\n None => {\n println!(\"The value was `None`\");\n }\n }\n}\n```\n" } , LintCompletion { label : "member_constraints" , description : "# `member_constraints`\n\nThe tracking issue for this feature is: [#61997]\n\n[#61997]: https://github.com/rust-lang/rust/issues/61997\n\n------------------------\n\nThe `member_constraints` feature gate lets you use `impl Trait` syntax with\nmultiple unrelated lifetime parameters.\n\nA simple example is:\n\n```rust\n#![feature(member_constraints)]\n\ntrait Trait<'a, 'b> { }\nimpl Trait<'_, '_> for T {}\n\nfn foo<'a, 'b>(x: &'a u32, y: &'b u32) -> impl Trait<'a, 'b> {\n (x, y)\n}\n\nfn main() { }\n```\n\nWithout the `member_constraints` feature gate, the above example is an\nerror because both `'a` and `'b` appear in the impl Trait bounds, but\nneither outlives the other.\n" } , LintCompletion { label : "optin_builtin_traits" , description : "# `optin_builtin_traits`\n\nThe tracking issue for this feature is [#13231] \n\n[#13231]: https://github.com/rust-lang/rust/issues/13231\n\n----\n\nThe `optin_builtin_traits` feature gate allows you to define auto traits.\n\nAuto traits, like [`Send`] or [`Sync`] in the standard library, are marker traits\nthat are automatically implemented for every type, unless the type, or a type it contains, \nhas explicitly opted out via a negative impl.

These automatic impls contain a where clause for each field\nof the form `T: AutoTrait`, where `T` is the type of the field and\n`AutoTrait` is the auto trait in question. As an example, consider the\nstruct `List` and the auto trait `Send`:\n\n```rust\nstruct List {\n data: T,\n next: Option>>,\n}\n```\n\nPresuming that there is no explicit impl of `Send` for `List`, the\ncompiler will supply an automatic impl of the form:\n\n```rust\nstruct List {\n data: T,\n next: Option>>,\n}\n\nunsafe impl Send for List\nwhere\n T: Send, // from the field `data`\n Option>>: Send, // from the field `next`\n{ }\n```\n\nExplicit impls may be either positive or negative. They take the form:\n\n```rust,ignore\nimpl<...> AutoTrait for StructName<..> { }\nimpl<...> !AutoTrait for StructName<..> { }\n```\n\n## Coinduction: Auto traits permit cyclic matching\n\nUnlike ordinary trait matching, auto traits are **coinductive**. This\nmeans, in short, that cycles which occur in trait matching are\nconsidered ok. As an example, consider the recursive struct `List`\nintroduced in the previous section. In attempting to determine whether\n`List: Send`, we would wind up in a cycle: to apply the impl, we must\nshow that `Option>: Send`, which will in turn require\n`Box: Send` and then finally `List: Send` again. Under ordinary\ntrait matching, this cycle would be an error, but for an auto trait it\nis considered a successful match.\n\n## Items\n\nAuto traits cannot have any trait items, such as methods or associated types. This ensures that we can generate default implementations.\n\n## Supertraits\n\nAuto traits cannot have supertraits.

These are normally\n// provided by libstd.\n#[lang = \"eh_personality\"]\n#[no_mangle]\npub extern fn rust_eh_personality() {\n}\n\n#[lang = \"panic_impl\"]\n#[no_mangle]\npub extern fn rust_begin_panic(info: &PanicInfo) -> ! {\n unsafe { intrinsics::abort() }\n}\n```\n\nIn many cases, you may need to manually link to the `compiler_builtins` crate\nwhen building a `no_std` binary. You may observe this via linker error messages\nsuch as \"```undefined reference to `__rust_probestack'```\".\n\n## More about the language items\n\nThe compiler currently makes a few assumptions about symbols which are\navailable in the executable to call. Normally these functions are provided by\nthe standard library, but without it you must define your own. These symbols\nare called \"language items\", and they each have an internal name, and then a\nsignature that an implementation must conform to.\n\nThe first of these functions, `rust_eh_personality`, is used by the failure\nmechanisms of the compiler. This is often mapped to GCC's personality function\n(see the [libstd implementation][unwind] for more information), but crates\nwhich do not trigger a panic can be assured that this function is never\ncalled. The language item's name is `eh_personality`.\n\n[unwind]: https://github.com/rust-lang/rust/blob/master/src/libpanic_unwind/gcc.rs\n\nThe second function, `rust_begin_panic`, is also used by the failure mechanisms of the\ncompiler. When a panic happens, this controls the message that's displayed on\nthe screen. While the language item's name is `panic_impl`, the symbol name is\n`rust_begin_panic`.\n\nFinally, a `eh_catch_typeinfo` static is needed for certain targets which\nimplement Rust panics on top of C++ exceptions.\n\n## List of all language items\n\nThis is a list of all language items in Rust along with where they are located in\nthe source code.\n\n- Primitives\n - `i8`: `libcore/num/mod.rs`\n - `i16`: `libcore/num/mod.rs`\n - `i32`: `libcore/num/mod.rs`\n - `i64`: `libcore/num/mod.rs`\n - `i128`: `libcore/num/mod.rs`\n - `isize`: `libcore/num/mod.rs`\n - `u8`: `libcore/num/mod.rs`\n - `u16`: `libcore/num/mod.rs`\n - `u32`: `libcore/num/mod.rs`\n - `u64`: `libcore/num/mod.rs`\n - `u128`: `libcore/num/mod.rs`\n - `usize`: `libcore/num/mod.rs`\n - `f32`: `libstd/f32.rs`\n - `f64`: `libstd/f64.rs`\n - `char`: `libcore/char.rs`\n - `slice`: `liballoc/slice.rs`\n - `str`: `liballoc/str.rs`\n - `const_ptr`: `libcore/ptr.rs`\n - `mut_ptr`: `libcore/ptr.rs`\n - `unsafe_cell`: `libcore/cell.rs`\n- Runtime\n - `start`: `libstd/rt.rs`\n - `eh_personality`: `libpanic_unwind/emcc.rs` (EMCC)\n - `eh_personality`: `libpanic_unwind/gcc.rs` (GNU)\n - `eh_personality`: `libpanic_unwind/seh.rs` (SEH)\n - `eh_catch_typeinfo`: `libpanic_unwind/emcc.rs` (EMCC)\n - `panic`: `libcore/panicking.rs`\n - `panic_bounds_check`: `libcore/panicking.rs`\n - `panic_impl`: `libcore/panicking.rs`\n - `panic_impl`: `libstd/panicking.rs`\n- Allocations\n - `owned_box`: `liballoc/boxed.rs`\n - `exchange_malloc`: `liballoc/heap.rs`\n - `box_free`: `liballoc/heap.rs`\n- Operands\n - `not`: `libcore/ops/bit.rs`\n - `bitand`: `libcore/ops/bit.rs`\n - `bitor`: `libcore/ops/bit.rs`\n - `bitxor`: `libcore/ops/bit.rs`\n - `shl`: `libcore/ops/bit.rs`\n - `shr`: `libcore/ops/bit.rs`\n - `bitand_assign`: `libcore/ops/bit.rs`\n - `bitor_assign`: `libcore/ops/bit.rs`\n - `bitxor_assign`: `libcore/ops/bit.rs`\n - `shl_assign`: `libcore/ops/bit.rs`\n - `shr_assign`: `libcore/ops/bit.rs`\n - `deref`: `libcore/ops/deref.rs`\n - `deref_mut`: `libcore/ops/deref.rs`\n - `index`: `libcore/ops/index.rs`\n - `index_mut`: `libcore/ops/index.rs`\n - `add`: `libcore/ops/arith.rs`\n - `sub`: `libcore/ops/arith.rs`\n - `mul`: `libcore/ops/arith.rs`\n - `div`: `libcore/ops/arith.rs`\n - `rem`: `libcore/ops/arith.rs`\n - `neg`: `libcore/ops/arith.rs`\n - `add_assign`: `libcore/ops/arith.rs`\n - `sub_assign`: `libcore/ops/arith.rs`\n - `mul_assign`: `libcore/ops/arith.rs`\n - `div_assign`: `libcore/ops/arith.rs`\n - `rem_assign`: `libcore/ops/arith.rs`\n - `eq`: `libcore/cmp.rs`\n - `ord`: `libcore/cmp.rs`\n- Functions\n - `fn`: `libcore/ops/function.rs`\n - `fn_mut`: `libcore/ops/function.rs`\n - `fn_once`: `libcore/ops/function.rs`\n - `generator_state`: `libcore/ops/generator.rs`\n - `generator`: `libcore/ops/generator.rs`\n- Other\n - `coerce_unsized`: `libcore/ops/unsize.rs`\n - `drop`: `libcore/ops/drop.rs`\n - `drop_in_place`: `libcore/ptr.rs`\n - `clone`: `libcore/clone.rs`\n - `copy`: `libcore/marker.rs`\n - `send`: `libcore/marker.rs`\n - `sized`: `libcore/marker.rs`\n - `unsize`: `libcore/marker.rs`\n - `sync`: `libcore/marker.rs`\n - `phantom_data`: `libcore/marker.rs`\n - `discriminant_kind`: `libcore/marker.rs`\n - `freeze`: `libcore/marker.rs`\n - `debug_trait`: `libcore/fmt/mod.rs`\n - `non_zero`: `libcore/nonzero.rs`\n - `arc`: `liballoc/sync.rs`\n - `rc`: `liballoc/rc.rs`\n" } , LintCompletion { label : "negative_impls" , description : "# `negative_impls`\n\nThe tracking issue for this feature is [#68318].\n\n[#68318]: https://github.com/rust-lang/rust/issues/68318\n\n----\n\nWith the feature gate `negative_impls`, you can write negative impls as well as positive ones:\n\n```rust\n#![feature(negative_impls)]\ntrait DerefMut { }\nimpl !DerefMut for &T { }\n```\n\nNegative impls indicate a semver guarantee that the given trait will not be implemented for the given types. Negative impls play an additional purpose for auto traits, described below.\n\nNegative impls have the following characteristics:\n\n* They do not have any items.\n* They must obey the orphan rules as if they were a positive impl.\n* They cannot \"overlap\" with any positive impls.\n\n## Semver interaction\n\nIt is a breaking change to remove a negative impl. Negative impls are a commitment not to implement the given trait for the named types.\n\n## Orphan and overlap rules\n\nNegative impls must obey the same orphan rules as a positive impl. This implies you cannot add a negative impl for types defined in upstream crates and so forth.\n\nSimilarly, negative impls cannot overlap with positive impls, again using the same \"overlap\" check that we ordinarily use to determine if two impls overlap. (Note that positive impls typically cannot overlap with one another either, except as permitted by specialization.)\n\n## Interaction with auto traits\n\nDeclaring a negative impl `impl !SomeAutoTrait for SomeType` for an\nauto-trait serves two purposes:\n\n* as with any trait, it declares that `SomeType` will never implement `SomeAutoTrait`;\n* it disables the automatic `SomeType: SomeAutoTrait` impl that would otherwise have been generated.\n\nNote that, at present, there is no way to indicate that a given type\ndoes not implement an auto trait *but that it may do so in the\nfuture*. For ordinary types, this is done by simply not declaring any\nimpl at all, but that is not an option for auto traits. A workaround\nis that one could embed a marker type as one of the fields, where the\nmarker type is `!AutoTrait`.\n\n## Immediate uses\n\nNegative impls are used to declare that `&T: !DerefMut` and `&mut T: !Clone`, as required to fix the soundness of `Pin` described in [#66544](https://github.com/rust-lang/rust/issues/66544).\n\nThis serves two purposes:\n\n* For proving the correctness of unsafe code, we can use that impl as evidence that no `DerefMut` or `Clone` impl exists.\n* It prevents downstream crates from creating such impls.\n" } , LintCompletion { label : "abi_ptx" , description : "# `abi_ptx`\n\nThe tracking issue for this feature is: [#38788]\n\n[#38788]: https://github.com/rust-lang/rust/issues/38788\n\n------------------------\n\nWhen emitting PTX code, all vanilla Rust functions (`fn`) get translated to\n\"device\" functions.

If all fields are zero-sized, the `union` must not be\n`#[repr(transparent)]`:\n\n```rust\n#![feature(transparent_unions)]\n\n// This (non-transparent) union is already valid in stable Rust:\npub union GoodUnion {\n pub nothing: (),\n}\n\n// Error: transparent union needs exactly one non-zero-sized field, but has 0\n// #[repr(transparent)]\n// pub union BadUnion {\n// pub nothing: (),\n// }\n```\n\nThe one exception is if the `union` is generic over `T` and has a field of type\n`T`, it may be `#[repr(transparent)]` even if `T` is a zero-sized type:\n\n```rust\n#![feature(transparent_unions)]\n\n// This union has the same representation as `T`.\n#[repr(transparent)]\npub union GenericUnion { // Unions with non-`Copy` fields are unstable.\n pub field: T,\n pub nothing: (),\n}\n\n// This is okay even though `()` is a zero-sized type.\npub const THIS_IS_OKAY: GenericUnion<()> = GenericUnion { field: () };\n```\n\nLike transarent `struct`s, a transparent `union` of type `U` has the same\nlayout, size, and ABI as its single non-ZST field. If it is generic over a type\n`T`, and all its fields are ZSTs except for exactly one field of type `T`, then\nit has the same layout and ABI as `T` (even if `T` is a ZST when monomorphized).\n\nLike transparent `struct`s, transparent `union`s are FFI-safe if and only if\ntheir underlying representation type is also FFI-safe.\n\nA `union` may not be eligible for the same nonnull-style optimizations that a\n`struct` or `enum` (with the same fields) are eligible for. Adding\n`#[repr(transparent)]` to `union` does not change this. To give a more concrete\nexample, it is unspecified whether `size_of::()` is equal to\n`size_of::>()`, where `T` is a `union` (regardless of whether or not\nit is transparent). The Rust compiler is free to perform this optimization if\npossible, but is not required to, and different compiler versions may differ in\ntheir application of these optimizations.\n" } , LintCompletion { label : "plugin" , description : "# `plugin`\n\nThe tracking issue for this feature is: [#29597]\n\n[#29597]: https://github.com/rust-lang/rust/issues/29597\n\n\nThis feature is part of \"compiler plugins.\" It will often be used with the\n[`plugin_registrar`] and `rustc_private` features.\n\n[`plugin_registrar`]: plugin-registrar.md\n\n------------------------\n\n`rustc` can load compiler plugins, which are user-provided libraries that\nextend the compiler's behavior with new lint checks, etc.\n\nA plugin is a dynamic library crate with a designated *registrar* function that\nregisters extensions with `rustc`. Other crates can load these extensions using\nthe crate attribute `#![plugin(...)]`. See the\n`rustc_driver::plugin` documentation for more about the\nmechanics of defining and loading a plugin.\n\nIn the vast majority of cases, a plugin should *only* be used through\n`#![plugin]` and not through an `extern crate` item. Linking a plugin would\npull in all of librustc_ast and librustc as dependencies of your crate. This is\ngenerally unwanted unless you are building another plugin.\n\nThe usual practice is to put compiler plugins in their own crate, separate from\nany `macro_rules!` macros or ordinary Rust code meant to be used by consumers\nof a library.\n\n# Lint plugins\n\nPlugins can extend [Rust's lint\ninfrastructure](../../reference/attributes/diagnostics.md#lint-check-attributes) with\nadditional checks for code style, safety, etc. Now let's write a plugin\n[`lint-plugin-test.rs`](https://github.com/rust-lang/rust/blob/master/src/test/ui-fulldeps/auxiliary/lint-plugin-test.rs)\nthat warns about any item named `lintme`.\n\n```rust,ignore\n#![feature(plugin_registrar)]\n#![feature(box_syntax, rustc_private)]\n\nextern crate rustc_ast;\n\n// Load rustc as a plugin to get macros\nextern crate rustc_driver;\n#[macro_use]\nextern crate rustc_lint;\n#[macro_use]\nextern crate rustc_session;\n\nuse rustc_driver::plugin::Registry;\nuse rustc_lint::{EarlyContext, EarlyLintPass, LintArray, LintContext, LintPass};\nuse rustc_ast::ast;\ndeclare_lint!(TEST_LINT, Warn, \"Warn about items named 'lintme'\");\n\ndeclare_lint_pass!(Pass => [TEST_LINT]);\n\nimpl EarlyLintPass for Pass {\n fn check_item(&mut self, cx: &EarlyContext, it: &ast::Item) {\n if it.ident.name.as_str() == \"lintme\" {\n cx.lint(TEST_LINT, |lint| {\n lint.build(\"item is named 'lintme'\").set_span(it.span).emit()\n });\n }\n }\n}\n\n#[plugin_registrar]\npub fn plugin_registrar(reg: &mut Registry) {\n reg.lint_store.register_lints(&[&TEST_LINT]);\n reg.lint_store.register_early_pass(|| box Pass);\n}\n```\n\nThen code like\n\n```rust,ignore\n#![feature(plugin)]\n#![plugin(lint_plugin_test)]\n\nfn lintme() { }\n```\n\nwill produce a compiler warning:\n\n```txt\nfoo.rs:4:1: 4:16 warning: item is named 'lintme', #[warn(test_lint)] on by default\nfoo.rs:4 fn lintme() { }\n ^~~~~~~~~~~~~~~\n```\n\nThe components of a lint plugin are:\n\n* one or more `declare_lint!` invocations, which define static `Lint` structs;\n\n* a struct holding any state needed by the lint pass (here, none);\n\n* a `LintPass`\n implementation defining how to check each syntax element. A single\n `LintPass` may call `span_lint` for several different `Lint`s, but should\n register them all through the `get_lints` method.\n\nLint passes are syntax traversals, but they run at a late stage of compilation\nwhere type information is available. `rustc`'s [built-in\nlints](https://github.com/rust-lang/rust/blob/master/src/librustc_session/lint/builtin.rs)\nmostly use the same infrastructure as lint plugins, and provide examples of how\nto access type information.\n\nLints defined by plugins are controlled by the usual [attributes and compiler\nflags](../../reference/attributes/diagnostics.md#lint-check-attributes), e.g.\n`#[allow(test_lint)]` or `-A test-lint`. These identifiers are derived from the\nfirst argument to `declare_lint!`, with appropriate case and punctuation\nconversion.\n\nYou can run `rustc -W help foo.rs` to see a list of lints known to `rustc`,\nincluding those provided by plugins loaded by `foo.rs`.\n" } , LintCompletion { label : "concat_idents" , description : "# `concat_idents`\n\nThe tracking issue for this feature is: [#29599]\n\n[#29599]: https://github.com/rust-lang/rust/issues/29599\n\n------------------------\n\nThe `concat_idents` feature adds a macro for concatenating multiple identifiers\ninto one identifier.\n\n## Examples\n\n```rust\n#![feature(concat_idents)]\n\nfn main() {\n fn foobar() -> u32 { 23 }\n let f = concat_idents!(foo, bar);\n assert_eq!(f(), 23);\n}\n```" } , LintCompletion { label : "update_panic_count" , description : "# `update_panic_count`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "fn_traits" , description : "# `fn_traits`\n\nThe tracking issue for this feature is [#29625]\n\nSee Also: [`unboxed_closures`](../language-features/unboxed-closures.md)\n\n[#29625]: https://github.com/rust-lang/rust/issues/29625\n\n----\n\nThe `fn_traits` feature allows for implementation of the [`Fn*`] traits\nfor creating custom closure-like types.\n\n[`Fn*`]: https://doc.rust-lang.org/std/ops/trait.Fn.html\n\n```rust\n#![feature(unboxed_closures)]\n#![feature(fn_traits)]\n\nstruct Adder {\n a: u32\n}\n\nimpl FnOnce<(u32, )> for Adder {\n type Output = u32;\n extern \"rust-call\" fn call_once(self, b: (u32, )) -> Self::Output {\n self.a + b.0\n }\n}\n\nfn main() {\n let adder = Adder { a: 3 };\n assert_eq!(adder(2), 5);\n}\n```\n" } , LintCompletion { label : "try_trait" , description : "# `try_trait`\n\nThe tracking issue for this feature is: [#42327]\n\n[#42327]: https://github.com/rust-lang/rust/issues/42327\n\n------------------------\n\nThis introduces a new trait `Try` for extending the `?` operator to types\nother than `Result` (a part of [RFC 1859]).

The macro is a no-frills\ninterface to LLVM's concept of [module-level inline assembly]. That is,\nall caveats applicable to LLVM's module-level inline assembly apply\nto `global_asm!`.\n\n[module-level inline assembly]: http://llvm.org/docs/LangRef.html#module-level-inline-assembly\n\n`global_asm!` fills a role not currently satisfied by either `asm!`\nor `#[naked]` functions. The programmer has _all_ features of the\nassembler at their disposal. The linker will expect to resolve any\nsymbols defined in the inline assembly, modulo any symbols marked as\nexternal. It also means syntax for directives and assembly follow the\nconventions of the assembler in your toolchain.\n\nA simple usage looks like this:\n\n```rust,ignore\n# #![feature(global_asm)]\n# you also need relevant target_arch cfgs\nglobal_asm!(include_str!(\"something_neato.s\"));\n```\n\nAnd a more complicated usage looks like this:\n\n```rust,ignore\n# #![feature(global_asm)]\n# #![cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n\npub mod sally {\n global_asm!(r#\"\n .global foo\n foo:\n jmp baz\n \"#);\n\n #[no_mangle]\n pub unsafe extern \"C\" fn baz() {}\n}\n\n// the symbols `foo` and `bar` are global, no matter where\n// `global_asm!` was used.\nextern \"C\" {\n fn foo();\n fn bar();\n}\n\npub mod harry {\n global_asm!(r#\"\n .global bar\n bar:\n jmp quux\n \"#);\n\n #[no_mangle]\n pub unsafe extern \"C\" fn quux() {}\n}\n```\n\nYou may use `global_asm!` multiple times, anywhere in your crate, in\nwhatever way suits you. The effect is as if you concatenated all\nusages and placed the larger, single usage in the crate root.\n\n------------------------\n\nIf you don't need quite as much power and flexibility as\n`global_asm!` provides, and you don't mind restricting your inline\nassembly to `fn` bodies only, you might try the\n[asm](asm.md) feature instead.\n" } , LintCompletion { label : "sort_internals" , description : "# `sort_internals`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "test" , description : "# `test`\n\nThe tracking issue for this feature is: None.\n\n------------------------\n\nThe internals of the `test` crate are unstable, behind the `test` flag. The\nmost widely used part of the `test` crate are benchmark tests, which can test\nthe performance of your code. Let's make our `src/lib.rs` look like this\n(comments elided):\n\n```rust,ignore\n#![feature(test)]\n\nextern crate test;\n\npub fn add_two(a: i32) -> i32 {\n a + 2\n}\n\n#[cfg(test)]\nmod tests {\n use super::*;\n use test::Bencher;\n\n #[test]\n fn it_works() {\n assert_eq!(4, add_two(2));\n }\n\n #[bench]\n fn bench_add_two(b: &mut Bencher) {\n b.iter(|| add_two(2));\n }\n}\n```\n\nNote the `test` feature gate, which enables this unstable feature.\n\nWe've imported the `test` crate, which contains our benchmarking support.\nWe have a new function as well, with the `bench` attribute. Unlike regular\ntests, which take no arguments, benchmark tests take a `&mut Bencher`. This\n`Bencher` provides an `iter` method, which takes a closure. This closure\ncontains the code we'd like to benchmark.\n\nWe can run benchmark tests with `cargo bench`:\n\n```bash\n$ cargo bench\n Compiling adder v0.0.1 (file:///home/steve/tmp/adder)\n Running target/release/adder-91b3e234d4ed382a\n\nrunning 2 tests\ntest tests::it_works ... ignored\ntest tests::bench_add_two ... bench: 1 ns/iter (+/- 0)\n\ntest result: ok. 0 passed; 0 failed; 1 ignored; 1 measured\n```\n\nOur non-benchmark test was ignored. You may have noticed that `cargo bench`\ntakes a bit longer than `cargo test`. This is because Rust runs our benchmark\na number of times, and then takes the average. Because we're doing so little\nwork in this example, we have a `1 ns/iter (+/- 0)`, but this would show\nthe variance if there was one.\n\nAdvice on writing benchmarks:\n\n\n* Move setup code outside the `iter` loop; only put the part you want to measure inside\n* Make the code do \"the same thing\" on each iteration; do not accumulate or change state\n* Make the outer function idempotent too; the benchmark runner is likely to run\n it many times\n* Make the inner `iter` loop short and fast so benchmark runs are fast and the\n calibrator can adjust the run-length at fine resolution\n* Make the code in the `iter` loop do something simple, to assist in pinpointing\n performance improvements (or regressions)\n\n## Gotcha: optimizations\n\nThere's another tricky part to writing benchmarks: benchmarks compiled with\noptimizations activated can be dramatically changed by the optimizer so that\nthe benchmark is no longer benchmarking what one expects. For example, the\ncompiler might recognize that some calculation has no external effects and\nremove it entirely.\n\n```rust,ignore\n#![feature(test)]\n\nextern crate test;\nuse test::Bencher;\n\n#[bench]\nfn bench_xor_1000_ints(b: &mut Bencher) {\n b.iter(|| {\n (0..1000).fold(0, |old, new| old ^ new);\n });\n}\n```\n\ngives the following results\n\n```text\nrunning 1 test\ntest bench_xor_1000_ints ... bench: 0 ns/iter (+/- 0)\n\ntest result: ok. 0 passed; 0 failed; 0 ignored; 1 measured\n```\n\nThe benchmarking runner offers two ways to avoid this. Either, the closure that\nthe `iter` method receives can return an arbitrary value which forces the\noptimizer to consider the result used and ensures it cannot remove the\ncomputation entirely. This could be done for the example above by adjusting the\n`b.iter` call to\n\n```rust\n# struct X;\n# impl X { fn iter(&self, _: F) where F: FnMut() -> T {} } let b = X;\nb.iter(|| {\n // Note lack of `;` (could also use an explicit `return`).\n (0..1000).fold(0, |old, new| old ^ new)\n});\n```\n\nOr, the other option is to call the generic `test::black_box` function, which\nis an opaque \"black box\" to the optimizer and so forces it to consider any\nargument as used.\n\n```rust\n#![feature(test)]\n\nextern crate test;\n\n# fn main() {\n# struct X;\n# impl X { fn iter(&self, _: F) where F: FnMut() -> T {} } let b = X;\nb.iter(|| {\n let n = test::black_box(1000);\n\n (0..n).fold(0, |a, b| a ^ b)\n})\n# }\n```\n\nNeither of these read or modify the value, and are very cheap for small values.\nLarger values can be passed indirectly to reduce overhead (e.g.\n`black_box(&huge_struct)`).\n\nPerforming either of the above changes gives the following benchmarking results\n\n```text\nrunning 1 test\ntest bench_xor_1000_ints ... bench: 131 ns/iter (+/- 3)\n\ntest result: ok. 0 passed; 0 failed; 0 ignored; 1 measured\n```\n\nHowever, the optimizer can still modify a testcase in an undesirable manner\neven when using either of the above.\n" } , LintCompletion { label : "windows_stdio" , description : "# `windows_stdio`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "allocator_api" , description : "# `allocator_api`\n\nThe tracking issue for this feature is [#32838]\n\n[#32838]: https://github.com/rust-lang/rust/issues/32838\n\n------------------------\n\nSometimes you want the memory for one collection to use a different\nallocator than the memory for another collection.

Rust supports using inline\nassembly to do this via the `asm!` macro.\n\n# Guide-level explanation\n[guide-level-explanation]: #guide-level-explanation\n\nRust provides support for inline assembly via the `asm!` macro.\nIt can be used to embed handwritten assembly in the assembly output generated by the compiler.\nGenerally this should not be necessary, but might be where the required performance or timing\ncannot be otherwise achieved. Accessing low level hardware primitives, e.g. in kernel code, may also demand this functionality.\n\n> **Note**: the examples here are given in x86/x86-64 assembly, but ARM, AArch64 and RISC-V are also supported.\n\n## Basic usage\n\nLet us start with the simplest possible example:\n\n```rust,allow_fail\n# #![feature(asm)]\nunsafe {\n asm!(\"nop\");\n}\n```\n\nThis will insert a NOP (no operation) instruction into the assembly generated by the compiler.\nNote that all `asm!` invocations have to be inside an `unsafe` block, as they could insert\narbitrary instructions and break various invariants. The instructions to be inserted are listed\nin the first argument of the `asm!` macro as a string literal.\n\n## Inputs and outputs\n\nNow inserting an instruction that does nothing is rather boring. Let us do something that\nactually acts on data:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet x: u64;\nunsafe {\n asm!(\"mov {}, 5\", out(reg) x);\n}\nassert_eq!(x, 5);\n```\n\nThis will write the value `5` into the `u64` variable `x`.\nYou can see that the string literal we use to specify instructions is actually a template string.\nIt is governed by the same rules as Rust [format strings][format-syntax].\nThe arguments that are inserted into the template however look a bit different then you may\nbe familiar with. First we need to specify if the variable is an input or an output of the\ninline assembly. In this case it is an output. We declared this by writing `out`.\nWe also need to specify in what kind of register the assembly expects the variable.\nIn this case we put it in an arbitrary general purpose register by specifying `reg`.\nThe compiler will choose an appropriate register to insert into\nthe template and will read the variable from there after the inline assembly finishes executing.\n\nLet us see another example that also uses an input:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet i: u64 = 3;\nlet o: u64;\nunsafe {\n asm!(\n \"mov {0}, {1}\",\n \"add {0}, {number}\",\n out(reg) o,\n in(reg) i,\n number = const 5,\n );\n}\nassert_eq!(o, 8);\n```\n\nThis will add `5` to the input in variable `i` and write the result to variable `o`.\nThe particular way this assembly does this is first copying the value from `i` to the output,\nand then adding `5` to it.\n\nThe example shows a few things:\n\nFirst, we can see that `asm!` allows multiple template string arguments; each\none is treated as a separate line of assembly code, as if they were all joined\ntogether with newlines between them. This makes it easy to format assembly\ncode.\n\nSecond, we can see that inputs are declared by writing `in` instead of `out`.\n\nThird, one of our operands has a type we haven't seen yet, `const`.\nThis tells the compiler to expand this argument to value directly inside the assembly template.\nThis is only possible for constants and literals.\n\nFourth, we can see that we can specify an argument number, or name as in any format string.\nFor inline assembly templates this is particularly useful as arguments are often used more than once.\nFor more complex inline assembly using this facility is generally recommended, as it improves\nreadability, and allows reordering instructions without changing the argument order.\n\nWe can further refine the above example to avoid the `mov` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut x: u64 = 3;\nunsafe {\n asm!(\"add {0}, {number}\", inout(reg) x, number = const 5);\n}\nassert_eq!(x, 8);\n```\n\nWe can see that `inout` is used to specify an argument that is both input and output.\nThis is different from specifying an input and output separately in that it is guaranteed to assign both to the same register.\n\nIt is also possible to specify different variables for the input and output parts of an `inout` operand:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet x: u64 = 3;\nlet y: u64;\nunsafe {\n asm!(\"add {0}, {number}\", inout(reg) x => y, number = const 5);\n}\nassert_eq!(y, 8);\n```\n\n## Late output operands\n\nThe Rust compiler is conservative with its allocation of operands. It is assumed that an `out`\ncan be written at any time, and can therefore not share its location with any other argument.\nHowever, to guarantee optimal performance it is important to use as few registers as possible,\nso they won't have to be saved and reloaded around the inline assembly block.\nTo achieve this Rust provides a `lateout` specifier. This can be used on any output that is\nwritten only after all inputs have been consumed.\nThere is also a `inlateout` variant of this specifier.\n\nHere is an example where `inlateout` *cannot* be used:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nlet c: u64 = 4;\nunsafe {\n asm!(\n \"add {0}, {1}\",\n \"add {0}, {2}\",\n inout(reg) a,\n in(reg) b,\n in(reg) c,\n );\n}\nassert_eq!(a, 12);\n```\n\nHere the compiler is free to allocate the same register for inputs `b` and `c` since it knows they have the same value. However it must allocate a separate register for `a` since it uses `inout` and not `inlateout`. If `inlateout` was used, then `a` and `c` could be allocated to the same register, in which case the first instruction to overwrite the value of `c` and cause the assembly code to produce the wrong result.\n\nHowever the following example can use `inlateout` since the output is only modified after all input registers have been read:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nunsafe {\n asm!(\"add {0}, {1}\", inlateout(reg) a, in(reg) b);\n}\nassert_eq!(a, 8);\n```\n\nAs you can see, this assembly fragment will still work correctly if `a` and `b` are assigned to the same register.\n\n## Explicit register operands\n\nSome instructions require that the operands be in a specific register.\nTherefore, Rust inline assembly provides some more specific constraint specifiers.\nWhile `reg` is generally available on any architecture, these are highly architecture specific. E.g. for x86 the general purpose registers `eax`, `ebx`, `ecx`, `edx`, `ebp`, `esi`, and `edi`\namong others can be addressed by their name.\n\n```rust,allow_fail,no_run\n# #![feature(asm)]\nlet cmd = 0xd1;\nunsafe {\n asm!(\"out 0x64, eax\", in(\"eax\") cmd);\n}\n```\n\nIn this example we call the `out` instruction to output the content of the `cmd` variable\nto port `0x64`. Since the `out` instruction only accepts `eax` (and its sub registers) as operand\nwe had to use the `eax` constraint specifier.\n\nNote that unlike other operand types, explicit register operands cannot be used in the template string: you can't use `{}` and should write the register name directly instead. Also, they must appear at the end of the operand list after all other operand types.\n\nConsider this example which uses the x86 `mul` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nfn mul(a: u64, b: u64) -> u128 {\n let lo: u64;\n let hi: u64;\n\n unsafe {\n asm!(\n // The x86 mul instruction takes rax as an implicit input and writes\n // the 128-bit result of the multiplication to rax:rdx.\n \"mul {}\",\n in(reg) a,\n inlateout(\"rax\") b => lo,\n lateout(\"rdx\") hi\n );\n }\n\n ((hi as u128) << 64) + lo as u128\n}\n```\n\nThis uses the `mul` instruction to multiply two 64-bit inputs with a 128-bit result.\nThe only explicit operand is a register, that we fill from the variable `a`.\nThe second operand is implicit, and must be the `rax` register, which we fill from the variable `b`.\nThe lower 64 bits of the result are stored in `rax` from which we fill the variable `lo`.\nThe higher 64 bits are stored in `rdx` from which we fill the variable `hi`.\n\n## Clobbered registers\n\nIn many cases inline assembly will modify state that is not needed as an output.\nUsually this is either because we have to use a scratch register in the assembly,\nor instructions modify state that we don't need to further examine.\nThis state is generally referred to as being \"clobbered\".\nWe need to tell the compiler about this since it may need to save and restore this state\naround the inline assembly block.\n\n```rust,allow_fail\n# #![feature(asm)]\nlet ebx: u32;\nlet ecx: u32;\n\nunsafe {\n asm!(\n \"cpuid\",\n // EAX 4 selects the \"Deterministic Cache Parameters\" CPUID leaf\n inout(\"eax\") 4 => _,\n // ECX 0 selects the L0 cache information.\n inout(\"ecx\") 0 => ecx,\n lateout(\"ebx\") ebx,\n lateout(\"edx\") _,\n );\n}\n\nprintln!(\n \"L1 Cache: {}\",\n ((ebx >> 22) + 1) * (((ebx >> 12) & 0x3ff) + 1) * ((ebx & 0xfff) + 1) * (ecx + 1)\n);\n```\n\nIn the example above we use the `cpuid` instruction to get the L1 cache size.\nThis instruction writes to `eax`, `ebx`, `ecx`, and `edx`, but for the cache size we only care about the contents of `ebx` and `ecx`.\n\nHowever we still need to tell the compiler that `eax` and `edx` have been modified so that it can save any values that were in these registers before the asm. This is done by declaring these as outputs but with `_` instead of a variable name, which indicates that the output value is to be discarded.\n\nThis can also be used with a general register class (e.g. `reg`) to obtain a scratch register for use inside the asm code:\n\n```rust,allow_fail\n# #![feature(asm)]\n// Multiply x by 6 using shifts and adds\nlet mut x: u64 = 4;\nunsafe {\n asm!(\n \"mov {tmp}, {x}\",\n \"shl {tmp}, 1\",\n \"shl {x}, 2\",\n \"add {x}, {tmp}\",\n x = inout(reg) x,\n tmp = out(reg) _,\n );\n}\nassert_eq!(x, 4 * 6);\n```\n\n## Symbol operands\n\nA special operand type, `sym`, allows you to use the symbol name of a `fn` or `static` in inline assembly code.\nThis allows you to call a function or access a global variable without needing to keep its address in a register.\n\n```rust,allow_fail\n# #![feature(asm)]\nextern \"C\" fn foo(arg: i32) {\n println!(\"arg = {}\", arg);\n}\n\nfn call_foo(arg: i32) {\n unsafe {\n asm!(\n \"call {}\",\n sym foo,\n // 1st argument in rdi, which is caller-saved\n inout(\"rdi\") arg => _,\n // All caller-saved registers must be marked as clobberred\n out(\"rax\") _, out(\"rcx\") _, out(\"rdx\") _, out(\"rsi\") _,\n out(\"r8\") _, out(\"r9\") _, out(\"r10\") _, out(\"r11\") _,\n out(\"xmm0\") _, out(\"xmm1\") _, out(\"xmm2\") _, out(\"xmm3\") _,\n out(\"xmm4\") _, out(\"xmm5\") _, out(\"xmm6\") _, out(\"xmm7\") _,\n out(\"xmm8\") _, out(\"xmm9\") _, out(\"xmm10\") _, out(\"xmm11\") _,\n out(\"xmm12\") _, out(\"xmm13\") _, out(\"xmm14\") _, out(\"xmm15\") _,\n )\n }\n}\n```\n\nNote that the `fn` or `static` item does not need to be public or `#[no_mangle]`:\nthe compiler will automatically insert the appropriate mangled symbol name into the assembly code.\n\n## Register template modifiers\n\nIn some cases, fine control is needed over the way a register name is formatted when inserted into the template string. This is needed when an architecture's assembly language has several names for the same register, each typically being a \"view\" over a subset of the register (e.g. the low 32 bits of a 64-bit register).\n\nBy default the compiler will always choose the name that refers to the full register size (e.g. `rax` on x86-64, `eax` on x86, etc).\n\nThis default can be overriden by using modifiers on the template string operands, just like you would with format strings:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut x: u16 = 0xab;\n\nunsafe {\n asm!(\"mov {0:h}, {0:l}\", inout(reg_abcd) x);\n}\n\nassert_eq!(x, 0xabab);\n```\n\nIn this example, we use the `reg_abcd` register class to restrict the register allocator to the 4 legacy x86 register (`ax`, `bx`, `cx`, `dx`) of which the first two bytes can be addressed independently.\n\nLet us assume that the register allocator has chosen to allocate `x` in the `ax` register.\nThe `h` modifier will emit the register name for the high byte of that register and the `l` modifier will emit the register name for the low byte. The asm code will therefore be expanded as `mov ah, al` which copies the low byte of the value into the high byte.\n\nIf you use a smaller data type (e.g. `u16`) with an operand and forget the use template modifiers, the compiler will emit a warning and suggest the correct modifier to use.\n\n## Options\n\nBy default, an inline assembly block is treated the same way as an external FFI function call with a custom calling convention: it may read/write memory, have observable side effects, etc. However in many cases, it is desirable to give the compiler more information about what the assembly code is actually doing so that it can optimize better.\n\nLet's take our previous example of an `add` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nunsafe {\n asm!(\n \"add {0}, {1}\",\n inlateout(reg) a, in(reg) b,\n options(pure, nomem, nostack),\n );\n}\nassert_eq!(a, 8);\n```\n\nOptions can be provided as an optional final argument to the `asm!` macro. We specified three options here:\n- `pure` means that the asm code has no observable side effects and that its output depends only on its inputs. This allows the compiler optimizer to call the inline asm fewer times or even eliminate it entirely.\n- `nomem` means that the asm code does not read or write to memory. By default the compiler will assume that inline assembly can read or write any memory address that is accessible to it (e.g. through a pointer passed as an operand, or a global).\n- `nostack` means that the asm code does not push any data onto the stack. This allows the compiler to use optimizations such as the stack red zone on x86-64 to avoid stack pointer adjustments.\n\nThese allow the compiler to better optimize code using `asm!`, for example by eliminating pure `asm!` blocks whose outputs are not needed.\n\nSee the reference for the full list of available options and their effects.\n\n# Reference-level explanation\n[reference-level-explanation]: #reference-level-explanation\n\nInline assembler is implemented as an unsafe macro `asm!()`.\nThe first argument to this macro is a template string literal used to build the final assembly.\nThe following arguments specify input and output operands.\nWhen required, options are specified as the final argument.\n\nThe following ABNF specifies the general syntax:\n\n```ignore\ndir_spec := \"in\" / \"out\" / \"lateout\" / \"inout\" / \"inlateout\"\nreg_spec := / \"\"\noperand_expr := expr / \"_\" / expr \"=>\" expr / expr \"=>\" \"_\"\nreg_operand := dir_spec \"(\" reg_spec \")\" operand_expr\noperand := reg_operand / \"const\" const_expr / \"sym\" path\noption := \"pure\" / \"nomem\" / \"readonly\" / \"preserves_flags\" / \"noreturn\" / \"att_syntax\"\noptions := \"options(\" option *[\",\" option] [\",\"] \")\"\nasm := \"asm!(\" format_string *(\",\" format_string) *(\",\" [ident \"=\"] operand) [\",\" options] [\",\"] \")\"\n```\n\nThe macro will initially be supported only on ARM, AArch64, Hexagon, x86, x86-64 and RISC-V targets. Support for more targets may be added in the future. The compiler will emit an error if `asm!` is used on an unsupported target.\n\n[format-syntax]: https://doc.rust-lang.org/std/fmt/#syntax\n\n## Template string arguments\n\nThe assembler template uses the same syntax as [format strings][format-syntax] (i.e. placeholders are specified by curly braces). The corresponding arguments are accessed in order, by index, or by name. However, implicit named arguments (introduced by [RFC #2795][rfc-2795]) are not supported.\n\nAn `asm!` invocation may have one or more template string arguments; an `asm!` with multiple template string arguments is treated as if all the strings were concatenated with a `\\n` between them. The expected usage is for each template string argument to correspond to a line of assembly code. All template string arguments must appear before any other arguments.\n\nAs with format strings, named arguments must appear after positional arguments. Explicit register operands must appear at the end of the operand list, after named arguments if any.\n\nExplicit register operands cannot be used by placeholders in the template string. All other named and positional operands must appear at least once in the template string, otherwise a compiler error is generated.\n\nThe exact assembly code syntax is target-specific and opaque to the compiler except for the way operands are substituted into the template string to form the code passed to the assembler.\n\nThe 5 targets specified in this RFC (x86, ARM, AArch64, RISC-V, Hexagon) all use the assembly code syntax of the GNU assembler (GAS). On x86, the `.intel_syntax noprefix` mode of GAS is used by default. On ARM, the `.syntax unified` mode is used. These targets impose an additional restriction on the assembly code: any assembler state (e.g. the current section which can be changed with `.section`) must be restored to its original value at the end of the asm string. Assembly code that does not conform to the GAS syntax will result in assembler-specific behavior.\n\n[rfc-2795]: https://github.com/rust-lang/rfcs/pull/2795\n\n## Operand type\n\nSeveral types of operands are supported:\n\n* `in() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain the value of `` at the start of the asm code.\n - The allocated register must contain the same value at the end of the asm code (except if a `lateout` is allocated to the same register).\n* `out() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain an undefined value at the start of the asm code.\n - `` must be a (possibly uninitialized) place expression, to which the contents of the allocated register is written to at the end of the asm code.\n - An underscore (`_`) may be specified instead of an expression, which will cause the contents of the register to be discarded at the end of the asm code (effectively acting as a clobber).\n* `lateout() `\n - Identical to `out` except that the register allocator can reuse a register allocated to an `in`.\n - You should only write to the register after all inputs are read, otherwise you may clobber an input.\n* `inout() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain the value of `` at the start of the asm code.\n - `` must be a mutable initialized place expression, to which the contents of the allocated register is written to at the end of the asm code.\n* `inout() => `\n - Same as `inout` except that the initial value of the register is taken from the value of ``.\n - `` must be a (possibly uninitialized) place expression, to which the contents of the allocated register is written to at the end of the asm code.\n - An underscore (`_`) may be specified instead of an expression for ``, which will cause the contents of the register to be discarded at the end of the asm code (effectively acting as a clobber).\n - `` and `` may have different types.\n* `inlateout() ` / `inlateout() => `\n - Identical to `inout` except that the register allocator can reuse a register allocated to an `in` (this can happen if the compiler knows the `in` has the same initial value as the `inlateout`).\n - You should only write to the register after all inputs are read, otherwise you may clobber an input.\n* `const `\n - `` must be an integer or floating-point constant expression.\n - The value of the expression is formatted as a string and substituted directly into the asm template string.\n* `sym `\n - `` must refer to a `fn` or `static`.\n - A mangled symbol name referring to the item is substituted into the asm template string.\n - The substituted string does not include any modifiers (e.g. GOT, PLT, relocations, etc).\n - `` is allowed to point to a `#[thread_local]` static, in which case the asm code can combine the symbol with relocations (e.g. `@plt`, `@TPOFF`) to read from thread-local data.\n\nOperand expressions are evaluated from left to right, just like function call arguments. After the `asm!` has executed, outputs are written to in left to right order. This is significant if two outputs point to the same place: that place will contain the value of the rightmost output.\n\n## Register operands\n\nInput and output operands can be specified either as an explicit register or as a register class from which the register allocator can select a register. Explicit registers are specified as string literals (e.g. `\"eax\"`) while register classes are specified as identifiers (e.g. `reg`). Using string literals for register names enables support for architectures that use special characters in register names, such as MIPS (`$0`, `$1`, etc).\n\nNote that explicit registers treat register aliases (e.g. `r14` vs `lr` on ARM) and smaller views of a register (e.g. `eax` vs `rax`) as equivalent to the base register. It is a compile-time error to use the same explicit register for two input operands or two output operands. Additionally, it is also a compile-time error to use overlapping registers (e.g. ARM VFP) in input operands or in output operands.\n\nOnly the following types are allowed as operands for inline assembly:\n- Integers (signed and unsigned)\n- Floating-point numbers\n- Pointers (thin only)\n- Function pointers\n- SIMD vectors (structs defined with `#[repr(simd)]` and which implement `Copy`). This includes architecture-specific vector types defined in `std::arch` such as `__m128` (x86) or `int8x16_t` (ARM).\n\nHere is the list of currently supported register classes:\n\n| Architecture | Register class | Registers | LLVM constraint code |\n| ------------ | -------------- | --------- | -------------------- |\n| x86 | `reg` | `ax`, `bx`, `cx`, `dx`, `si`, `di`, `r[8-15]` (x86-64 only) | `r` |\n| x86 | `reg_abcd` | `ax`, `bx`, `cx`, `dx` | `Q` |\n| x86-32 | `reg_byte` | `al`, `bl`, `cl`, `dl`, `ah`, `bh`, `ch`, `dh` | `q` |\n| x86-64 | `reg_byte` | `al`, `bl`, `cl`, `dl`, `sil`, `dil`, `r[8-15]b`, `ah`\\*, `bh`\\*, `ch`\\*, `dh`\\* | `q` |\n| x86 | `xmm_reg` | `xmm[0-7]` (x86) `xmm[0-15]` (x86-64) | `x` |\n| x86 | `ymm_reg` | `ymm[0-7]` (x86) `ymm[0-15]` (x86-64) | `x` |\n| x86 | `zmm_reg` | `zmm[0-7]` (x86) `zmm[0-31]` (x86-64) | `v` |\n| x86 | `kreg` | `k[1-7]` | `Yk` |\n| AArch64 | `reg` | `x[0-28]`, `x30` | `r` |\n| AArch64 | `vreg` | `v[0-31]` | `w` |\n| AArch64 | `vreg_low16` | `v[0-15]` | `x` |\n| ARM | `reg` | `r[0-5]` `r7`\\*, `r[8-10]`, `r11`\\*, `r12`, `r14` | `r` |\n| ARM (Thumb) | `reg_thumb` | `r[0-r7]` | `l` |\n| ARM (ARM) | `reg_thumb` | `r[0-r10]`, `r12`, `r14` | `l` |\n| ARM | `sreg` | `s[0-31]` | `t` |\n| ARM | `sreg_low16` | `s[0-15]` | `x` |\n| ARM | `dreg` | `d[0-31]` | `w` |\n| ARM | `dreg_low16` | `d[0-15]` | `t` |\n| ARM | `dreg_low8` | `d[0-8]` | `x` |\n| ARM | `qreg` | `q[0-15]` | `w` |\n| ARM | `qreg_low8` | `q[0-7]` | `t` |\n| ARM | `qreg_low4` | `q[0-3]` | `x` |\n| NVPTX | `reg16` | None\\* | `h` |\n| NVPTX | `reg32` | None\\* | `r` |\n| NVPTX | `reg64` | None\\* | `l` |\n| RISC-V | `reg` | `x1`, `x[5-7]`, `x[9-15]`, `x[16-31]` (non-RV32E) | `r` |\n| RISC-V | `freg` | `f[0-31]` | `f` |\n| Hexagon | `reg` | `r[0-28]` | `r` |\n\n> **Note**: On x86 we treat `reg_byte` differently from `reg` because the compiler can allocate `al` and `ah` separately whereas `reg` reserves the whole register.\n>\n> Note #2: On x86-64 the high byte registers (e.g. `ah`) are only available when used as an explicit register. Specifying the `reg_byte` register class for an operand will always allocate a low byte register.\n>\n> Note #3: NVPTX doesn't have a fixed register set, so named registers are not supported.\n>\n> Note #4: On ARM the frame pointer is either `r7` or `r11` depending on the platform.\n\nAdditional register classes may be added in the future based on demand (e.g. MMX, x87, etc).\n\nEach register class has constraints on which value types they can be used with. This is necessary because the way a value is loaded into a register depends on its type. For example, on big-endian systems, loading a `i32x4` and a `i8x16` into a SIMD register may result in different register contents even if the byte-wise memory representation of both values is identical. The availability of supported types for a particular register class may depend on what target features are currently enabled.\n\n| Architecture | Register class | Target feature | Allowed types |\n| ------------ | -------------- | -------------- | ------------- |\n| x86-32 | `reg` | None | `i16`, `i32`, `f32` |\n| x86-64 | `reg` | None | `i16`, `i32`, `f32`, `i64`, `f64` |\n| x86 | `reg_byte` | None | `i8` |\n| x86 | `xmm_reg` | `sse` | `i32`, `f32`, `i64`, `f64`,

The only exception is the `freg` register class on RISC-V where `f32` values are NaN-boxed in a `f64` as required by the RISC-V architecture.\n\nWhen separate input and output expressions are specified for an `inout` operand, both expressions must have the same type. The only exception is if both operands are pointers or integers, in which case they are only required to have the same size. This restriction exists because the register allocators in LLVM and GCC sometimes cannot handle tied operands with different types.\n\n## Register names\n\nSome registers have multiple names. These are all treated by the compiler as identical to the base register name. Here is the list of all supported register aliases:\n\n| Architecture | Base register | Aliases |\n| ------------ | ------------- | ------- |\n| x86 | `ax` | `eax`, `rax` |\n| x86 | `bx` | `ebx`, `rbx` |\n| x86 | `cx` | `ecx`, `rcx` |\n| x86 | `dx` | `edx`, `rdx` |\n| x86 | `si` | `esi`, `rsi` |\n| x86 | `di` | `edi`, `rdi` |\n| x86 | `bp` | `bpl`, `ebp`, `rbp` |\n| x86 | `sp` | `spl`, `esp`, `rsp` |\n| x86 | `ip` | `eip`, `rip` |\n| x86 | `st(0)` | `st` |\n| x86 | `r[8-15]` | `r[8-15]b`, `r[8-15]w`, `r[8-15]d` |\n| x86 | `xmm[0-31]` | `ymm[0-31]`, `zmm[0-31]` |\n| AArch64 | `x[0-30]` | `w[0-30]` |\n| AArch64 | `x29` | `fp` |\n| AArch64 | `x30` | `lr` |\n| AArch64 | `sp` | `wsp` |\n| AArch64 | `xzr` | `wzr` |\n| AArch64 | `v[0-31]` | `b[0-31]`, `h[0-31]`, `s[0-31]`, `d[0-31]`, `q[0-31]` |\n| ARM | `r[0-3]` | `a[1-4]` |\n| ARM | `r[4-9]` | `v[1-6]` |\n| ARM | `r9` | `rfp` |\n| ARM | `r10` | `sl` |\n| ARM | `r11` | `fp` |\n| ARM | `r12` | `ip` |\n| ARM | `r13` | `sp` |\n| ARM | `r14` | `lr` |\n| ARM | `r15` | `pc` |\n| RISC-V | `x0` | `zero` |\n| RISC-V | `x1` | `ra` |\n| RISC-V | `x2` | `sp` |\n| RISC-V | `x3` | `gp` |\n| RISC-V | `x4` | `tp` |\n| RISC-V | `x[5-7]` | `t[0-2]` |\n| RISC-V | `x8` | `fp`, `s0` |\n| RISC-V | `x9` | `s1` |\n| RISC-V | `x[10-17]` | `a[0-7]` |\n| RISC-V | `x[18-27]` | `s[2-11]` |\n| RISC-V | `x[28-31]` | `t[3-6]` |\n| RISC-V | `f[0-7]` | `ft[0-7]` |\n| RISC-V | `f[8-9]` | `fs[0-1]` |\n| RISC-V | `f[10-17]` | `fa[0-7]` |\n| RISC-V | `f[18-27]` | `fs[2-11]` |\n| RISC-V | `f[28-31]` | `ft[8-11]` |\n| Hexagon | `r29` | `sp` |\n| Hexagon | `r30` | `fr` |\n| Hexagon | `r31` | `lr` |\n\nSome registers cannot be used for input or output operands:\n\n| Architecture | Unsupported register | Reason |\n| ------------ | -------------------- | ------ |\n| All | `sp` | The stack pointer must be restored to its original value at the end of an asm code block. |\n| All | `bp` (x86), `x29` (AArch64), `x8` (RISC-V), `fr` (Hexagon) | The frame pointer cannot be used as an input or output. |\n| ARM | `r7` or `r11` | On ARM the frame pointer can be either `r7` or `r11` depending on the target. The frame pointer cannot be used as an input or output. |\n| ARM | `r6` | `r6` is used internally by LLVM as a base pointer and therefore cannot be used as an input or output. |\n| x86 | `k0` | This is a constant zero register which can't be modified. |\n| x86 | `ip` | This is the program counter, not a real register. |\n| x86 | `mm[0-7]` | MMX registers are not currently supported (but may be in the future). |\n| x86 | `st([0-7])` | x87 registers are not currently supported (but may be in the future). |\n| AArch64 | `xzr` | This is a constant zero register which can't be modified. |\n| ARM | `pc` | This is the program counter, not a real register. |\n| RISC-V | `x0` | This is a constant zero register which can't be modified. |\n| RISC-V | `gp`, `tp` | These registers are reserved and cannot be used as inputs or outputs. |\n| Hexagon | `lr` | This is the link register which cannot be used as an input or output. |\n\n## Template modifiers\n\nThe placeholders can be augmented by modifiers which are specified after the `:` in the curly braces. These modifiers do not affect register allocation, but change the way operands are formatted when inserted into the template string. Only one modifier is allowed per template placeholder.\n\nThe supported modifiers are a subset of LLVM's (and GCC's) [asm template argument modifiers][llvm-argmod], but do not use the same letter codes.\n\n| Architecture | Register class | Modifier | Example output | LLVM modifier |\n| ------------ | -------------- | -------- | -------------- | ------------- |\n| x86-32 | `reg` | None | `eax` | `k` |\n| x86-64 | `reg` | None | `rax` | `q` |\n| x86-32 | `reg_abcd` | `l` | `al` | `b` |\n| x86-64 | `reg` | `l` | `al` | `b` |\n| x86 | `reg_abcd` | `h` | `ah` | `h` |\n| x86 | `reg` | `x` | `ax` | `w` |\n| x86 | `reg` | `e` | `eax` | `k` |\n| x86-64 | `reg` | `r` | `rax` | `q` |\n| x86 | `reg_byte` | None | `al` / `ah` | None |\n| x86 | `xmm_reg` | None | `xmm0` | `x` |\n| x86 | `ymm_reg` | None | `ymm0` | `t` |\n| x86 | `zmm_reg` | None | `zmm0` | `g` |\n| x86 | `*mm_reg` | `x` | `xmm0` | `x` |\n| x86 | `*mm_reg` | `y` | `ymm0` | `t` |\n| x86 | `*mm_reg` | `z` | `zmm0` | `g` |\n| x86 | `kreg` | None | `k1` | None |\n| AArch64 | `reg` | None | `x0` | `x` |\n| AArch64 | `reg` | `w` | `w0` | `w` |\n| AArch64 | `reg` | `x` | `x0` | `x` |\n| AArch64 | `vreg` | None | `v0` | None |\n| AArch64 | `vreg` | `v` | `v0` | None |\n| AArch64 | `vreg` | `b` | `b0` | `b` |\n| AArch64 | `vreg` | `h` | `h0` | `h` |\n| AArch64 | `vreg` | `s` | `s0` | `s` |\n| AArch64 | `vreg` | `d` | `d0` | `d` |\n| AArch64 | `vreg` | `q` | `q0` | `q` |\n| ARM | `reg` | None | `r0` | None |\n| ARM | `sreg` | None | `s0` | None |\n| ARM | `dreg` | None | `d0` | `P` |\n| ARM | `qreg` | None | `q0` | `q` |\n| ARM | `qreg` | `e` / `f` | `d0` / `d1` | `e` / `f` |\n| NVPTX | `reg16` | None | `rs0` | None |\n| NVPTX | `reg32` | None | `r0` | None |\n| NVPTX | `reg64` | None | `rd0` | None |\n| RISC-V | `reg` | None | `x1` | None |\n| RISC-V | `freg` | None | `f0` | None |\n| Hexagon | `reg` | None | `r0` | None |\n\n> Notes:\n> - on ARM `e` / `f`: this prints the low or high doubleword register name of a NEON quad (128-bit) register.\n> - on x86: our behavior for `reg` with no modifiers differs from what GCC does. GCC will infer the modifier based on the operand value type, while we default to the full register size.\n> - on x86 `xmm_reg`: the `x`, `t` and `g` LLVM modifiers are not yet implemented in LLVM (they are supported by GCC only), but this should be a simple change.\n\nAs stated in the previous section, passing an input value smaller than the register width will result in the upper bits of the register containing undefined values. This is not a problem if the inline asm only accesses the lower bits of the register, which can be done by using a template modifier to use a subregister name in the asm code (e.g. `ax` instead of `rax`). Since this an easy pitfall, the compiler will suggest a template modifier to use where appropriate given the input type. If all references to an operand already have modifiers then the warning is suppressed for that operand.\n\n[llvm-argmod]: http://llvm.org/docs/LangRef.html#asm-template-argument-modifiers\n\n## Options\n\nFlags are used to further influence the behavior of the inline assembly block.\nCurrently the following options are defined:\n- `pure`: The `asm` block has no side effects, and its outputs depend only on its direct inputs (i.e. the values themselves, not what they point to) or values read from memory (unless the `nomem` options is also set). This allows the compiler to execute the `asm` block fewer times than specified in the program (e.g. by hoisting it out of a loop) or even eliminate it entirely if the outputs are not used.\n- `nomem`: The `asm` blocks does not read or write to any memory. This allows the compiler to cache the values of modified global variables in registers across the `asm` block since it knows that they are not read or written to by the `asm`.\n- `readonly`: The `asm` block does not write to any memory. This allows the compiler to cache the values of unmodified global variables in registers across the `asm` block since it knows that they are not written to by the `asm`.\n- `preserves_flags`: The `asm` block does not modify the flags register (defined in the rules below). This allows the compiler to avoid recomputing the condition flags after the `asm` block.\n- `noreturn`: The `asm` block never returns, and its return type is defined as `!` (never). Behavior is undefined if execution falls through past the end of the asm code. A `noreturn` asm block behaves just like a function which doesn't return; notably, local variables in scope are not dropped before it is invoked.\n- `nostack`: The `asm` block does not push data to the stack, or write to the stack red-zone (if supported by the target). If this option is *not* used then the stack pointer is guaranteed to be suitably aligned (according to the target ABI) for a function call.\n- `att_syntax`: This option is only valid on x86, and causes the assembler to use the `.att_syntax prefix` mode of the GNU assembler. Register operands are substituted in with a leading `%`.\n\nThe compiler performs some additional checks on options:\n- The `nomem` and `readonly` options are mutually exclusive: it is a compile-time error to specify both.\n- The `pure` option must be combined with either the `nomem` or `readonly` options, otherwise a compile-time error is emitted.\n- It is a compile-time error to specify `pure` on an asm block with no outputs or only discarded outputs (`_`).\n- It is a compile-time error to specify `noreturn` on an asm block with outputs.\n\n## Rules for inline assembly\n\n- Any registers not specified as inputs will contain an undefined value on entry to the asm block.\n - An \"undefined value\" in the context of inline assembly means that the register can (non-deterministically) have any one of the possible values allowed by the architecture. Notably it is not the same as an LLVM `undef` which can have a different value every time you read it (since such a concept does not exist in assembly code).\n- Any registers not specified as outputs must have the same value upon exiting the asm block as they had on entry, otherwise behavior is undefined.\n - This only applies to registers which can be specified as an input or output. Other registers follow target-specific rules.\n - Note that a `lateout` may be allocated to the same register as an `in`, in which case this rule does not apply. Code should not rely on this however since it depends on the results of register allocation.\n- Behavior is undefined if execution unwinds out of an asm block.\n - This also applies if the assembly code calls a function which then unwinds.\n- The set of memory locations that assembly code is allowed the read and write are the same as those allowed for an FFI function.\n - Refer to the unsafe code guidelines for the exact rules.\n - If the `readonly` option is set, then only memory reads are allowed.\n - If the `nomem` option is set then no reads or writes to memory are allowed.\n - These rules do not apply to memory which is private to the asm code, such as stack space allocated within the asm block.\n- The compiler cannot assume that the instructions in the asm are the ones that will actually end up executed.\n - This effectively means that the compiler must treat the `asm!` as a black box and only take the interface specification into account, not the instructions themselves.\n - Runtime code patching is allowed, via target-specific mechanisms (outside the scope of this RFC).\n- Unless the `nostack` option is set, asm code is allowed to use stack space below the stack pointer.\n - On entry to the asm block the stack pointer is guaranteed to be suitably aligned (according to the target ABI) for a function call.\n - You are responsible for making sure you don't overflow the stack (e.g. use stack probing to ensure you hit a guard page).\n - You should adjust the stack pointer when allocating stack memory as required by the target ABI.\n - The stack pointer must be restored to its original value before leaving the asm block.\n- If the `noreturn` option is set then behavior is undefined if execution falls through to the end of the asm block.\n- If the `pure` option is set then behavior is undefined if the `asm` has side-effects other than its direct outputs. Behavior is also undefined if two executions of the `asm` code with the same inputs result in different outputs.\n - When used with the `nomem` option, \"inputs\" are just the direct inputs of the `asm!`.\n - When used with the `readonly` option, \"inputs\" comprise the direct inputs of the `asm!` and any memory that the `asm!` block is allowed to read.\n- These flags registers must be restored upon exiting the asm block if the `preserves_flags` option is set:\n - x86\n - Status flags in `EFLAGS` (CF, PF, AF, ZF, SF, OF).\n - Floating-point status word (all).\n - Floating-point exception flags in `MXCSR` (PE, UE, OE, ZE, DE, IE).\n - ARM\n - Condition flags in `CPSR` (N, Z, C, V)\n - Saturation flag in `CPSR` (Q)\n - Greater than or equal flags in `CPSR` (GE).\n - Condition flags in `FPSCR` (N, Z, C, V)\n - Saturation flag in `FPSCR` (QC)\n - Floating-point exception flags in `FPSCR` (IDC, IXC, UFC, OFC, DZC, IOC).\n - AArch64\n - Condition flags (`NZCV` register).\n - Floating-point status (`FPSR` register).\n - RISC-V\n - Floating-point exception flags in `fcsr` (`fflags`).\n- On x86, the direction flag (DF in `EFLAGS`) is clear on entry to an asm block and must be clear on exit.\n - Behavior is undefined if the direction flag is set on exiting an asm block.\n- The requirement of restoring the stack pointer and non-output registers to their original value only applies when exiting an `asm!` block.\n - This means that `asm!` blocks that never return (even if not marked `noreturn`) don't need to preserve these registers.\n - When returning to a different `asm!` block than you entered (e.g. for context switching), these registers must contain the value they had upon entering the `asm!` block that you are *exiting*.\n - You cannot exit an `asm!` block that has not been entered. Neither can you exit an `asm!` block that has already been exited.\n - You are responsible for switching any target-specific state (e.g. thread-local storage, stack bounds).\n - The set of memory locations that you may access is the intersection of those allowed by the `asm!` blocks you entered and exited.\n- You cannot assume that an `asm!` block will appear exactly once in the output binary. The compiler is allowed to instantiate multiple copies of the `asm!` block, for example when the function containing it is inlined in multiple places.\n - As a consequence, you should only use [local labels] inside inline assembly code. Defining symbols in assembly code may lead to assembler and/or linker errors due to duplicate symbol definitions.\n\n> **Note**: As a general rule, the flags covered by `preserves_flags` are those which are *not* preserved when performing a function call.\n\n[local labels]: https://sourceware.org/binutils/docs/as/Symbol-Names.html#Local-Labels\n" } , LintCompletion { label : "is_sorted" ,

This is useful for very low level programming, where\nwhich register you use is important:\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# unsafe fn read_byte_in(port: u16) -> u8 {\nlet result: u8;\nllvm_asm!(\"in %dx, %al\" : \"={al}\"(result) : \"{dx}\"(port));\nresult\n# }\n```\n\n## Clobbers\n\nSome instructions modify registers which might otherwise have held\ndifferent values so we use the clobbers list to indicate to the\ncompiler not to assume any values loaded into those registers will\nstay valid.\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# fn main() { unsafe {\n// Put the value 0x200 in eax:\nllvm_asm!(\"mov $$0x200, %eax\" : /* no outputs */ : /* no inputs */ : \"eax\");\n# } }\n# #[cfg(not(any(target_arch = \"x86\", target_arch = \"x86_64\")))]\n# fn main() {}\n```\n\nInput and output registers need not be listed since that information\nis already communicated by the given constraints. Otherwise, any other\nregisters used either implicitly or explicitly should be listed.\n\nIf the assembly changes the condition code register `cc` should be\nspecified as one of the clobbers. Similarly, if the assembly modifies\nmemory, `memory` should also be specified.\n\n## Options\n\nThe last section, `options` is specific to Rust. The format is comma\nseparated literal strings (i.e. `:\"foo\", \"bar\", \"baz\"`). It's used to\nspecify some extra info about the inline assembly:\n\nCurrent valid options are:\n\n1. *volatile* - specifying this is analogous to\n `__asm__ __volatile__ (...)` in gcc/clang.\n2. *alignstack* - certain instructions expect the stack to be\n aligned a certain way (i.e. SSE) and specifying this indicates to\n the compiler to insert its usual stack alignment code\n3. *intel* - use intel syntax instead of the default AT&T.\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# fn main() {\nlet result: i32;\nunsafe {\n llvm_asm!(\"mov eax, 2\" : \"={eax}\"(result) : : : \"intel\")\n}\nprintln!(\"eax is currently {}\", result);\n# }\n# #[cfg(not(any(target_arch = \"x86\", target_arch = \"x86_64\")))]\n# fn main() {}\n```\n\n## More Information\n\nThe current implementation of the `llvm_asm!` macro is a direct binding to [LLVM's\ninline assembler expressions][llvm-docs], so be sure to check out [their\ndocumentation as well][llvm-docs] for more information about clobbers,\nconstraints, etc.\n\n[llvm-docs]: http://llvm.org/docs/LangRef.html#inline-assembler-expressions\n\nIf you need more power and don't mind losing some of the niceties of\n`llvm_asm!`, check out [global_asm](global-asm.md).\n" } ] ; +pub(crate) const UNSTABLE_FEATURE_DESCRIPTOR : & [ LintCompletion ] = & [ LintCompletion { label : "crate_visibility_modifier" , description : "# `crate_visibility_modifier`\n\nThe tracking issue for this feature is: [#53120]\n\n[#53120]: https://github.com/rust-lang/rust/issues/53120\n\n-----\n\nThe `crate_visibility_modifier` feature allows the `crate` keyword to be used\nas a visibility modifier synonymous to `pub(crate)`, indicating that a type\n(function, _&c._) is to be visible to the entire enclosing crate, but not to\nother crates.\n\n```rust\n#![feature(crate_visibility_modifier)]\n\ncrate struct Foo {\n bar: usize,\n}\n```\n" } , LintCompletion { label : "abi_thiscall" , description : "# `abi_thiscall`\n\nThe tracking issue for this feature is: [#42202]\n\n[#42202]: https://github.com/rust-lang/rust/issues/42202\n\n------------------------\n\nThe MSVC ABI on x86 Windows uses the `thiscall` calling convention for C++\ninstance methods by default; it is identical to the usual (C) calling\nconvention on x86 Windows except that the first parameter of the method,\nthe `this` pointer, is passed in the ECX register.\n" } , LintCompletion { label : "infer_static_outlives_requirements" , description : "# `infer_static_outlives_requirements`\n\nThe tracking issue for this feature is: [#54185]\n\n[#54185]: https://github.com/rust-lang/rust/issues/54185\n\n------------------------\nThe `infer_static_outlives_requirements` feature indicates that certain\n`'static` outlives requirements can be inferred by the compiler rather than\nstating them explicitly.\n\nNote: It is an accompanying feature to `infer_outlives_requirements`,\nwhich must be enabled to infer outlives requirements.\n\nFor example, currently generic struct definitions that contain\nreferences, require where-clauses of the form T: 'static.

A generator is a \"resumable function\" that syntactically\nresembles a closure but compiles to much different semantics in the compiler\nitself. The primary feature of a generator is that it can be suspended during\nexecution to be resumed at a later date. Generators use the `yield` keyword to\n\"return\", and then the caller can `resume` a generator to resume execution just\nafter the `yield` keyword.\n\nGenerators are an extra-unstable feature in the compiler right now. Added in\n[RFC 2033] they're mostly intended right now as a information/constraint\ngathering phase. The intent is that experimentation can happen on the nightly\ncompiler before actual stabilization. A further RFC will be required to\nstabilize generators/coroutines and will likely contain at least a few small\ntweaks to the overall design.\n\n[RFC 2033]: https://github.com/rust-lang/rfcs/pull/2033\n\nA syntactical example of a generator is:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::{Generator, GeneratorState};\nuse std::pin::Pin;\n\nfn main() {\n let mut generator = || {\n yield 1;\n return \"foo\"\n };\n\n match Pin::new(&mut generator).resume(()) {\n GeneratorState::Yielded(1) => {}\n _ => panic!(\"unexpected value from resume\"),\n }\n match Pin::new(&mut generator).resume(()) {\n GeneratorState::Complete(\"foo\") => {}\n _ => panic!(\"unexpected value from resume\"),\n }\n}\n```\n\nGenerators are closure-like literals which can contain a `yield` statement. The\n`yield` statement takes an optional expression of a value to yield out of the\ngenerator. All generator literals implement the `Generator` trait in the\n`std::ops` module. The `Generator` trait has one main method, `resume`, which\nresumes execution of the generator at the previous suspension point.\n\nAn example of the control flow of generators is that the following example\nprints all numbers in order:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::Generator;\nuse std::pin::Pin;\n\nfn main() {\n let mut generator = || {\n println!(\"2\");\n yield;\n println!(\"4\");\n };\n\n println!(\"1\");\n Pin::new(&mut generator).resume(());\n println!(\"3\");\n Pin::new(&mut generator).resume(());\n println!(\"5\");\n}\n```\n\nAt this time the main intended use case of generators is an implementation\nprimitive for async/await syntax, but generators will likely be extended to\nergonomic implementations of iterators and other primitives in the future.\nFeedback on the design and usage is always appreciated!\n\n### The `Generator` trait\n\nThe `Generator` trait in `std::ops` currently looks like:\n\n```rust\n# #![feature(arbitrary_self_types, generator_trait)]\n# use std::ops::GeneratorState;\n# use std::pin::Pin;\n\npub trait Generator {\n type Yield;\n type Return;\n fn resume(self: Pin<&mut Self>, resume: R) -> GeneratorState;\n}\n```\n\nThe `Generator::Yield` type is the type of values that can be yielded with the\n`yield` statement. The `Generator::Return` type is the returned type of the\ngenerator. This is typically the last expression in a generator's definition or\nany value passed to `return` in a generator. The `resume` function is the entry\npoint for executing the `Generator` itself.\n\nThe return value of `resume`, `GeneratorState`, looks like:\n\n```rust\npub enum GeneratorState {\n Yielded(Y),\n Complete(R),\n}\n```\n\nThe `Yielded` variant indicates that the generator can later be resumed. This\ncorresponds to a `yield` point in a generator. The `Complete` variant indicates\nthat the generator is complete and cannot be resumed again. Calling `resume`\nafter a generator has returned `Complete` will likely result in a panic of the\nprogram.\n\n### Closure-like semantics\n\nThe closure-like syntax for generators alludes to the fact that they also have\nclosure-like semantics. Namely:\n\n* When created, a generator executes no code. A closure literal does not\n actually execute any of the closure's code on construction, and similarly a\n generator literal does not execute any code inside the generator when\n constructed.\n\n* Generators can capture outer variables by reference or by move, and this can\n be tweaked with the `move` keyword at the beginning of the closure. Like\n closures all generators will have an implicit environment which is inferred by\n the compiler. Outer variables can be moved into a generator for use as the\n generator progresses.\n\n* Generator literals produce a value with a unique type which implements the\n `std::ops::Generator` trait. This allows actual execution of the generator\n through the `Generator::resume` method as well as also naming it in return\n types and such.\n\n* Traits like `Send` and `Sync` are automatically implemented for a `Generator`\n depending on the captured variables of the environment. Unlike closures,\n generators also depend on variables live across suspension points. This means\n that although the ambient environment may be `Send` or `Sync`, the generator\n itself may not be due to internal variables live across `yield` points being\n not-`Send` or not-`Sync`. Note that generators do\n not implement traits like `Copy` or `Clone` automatically.\n\n* Whenever a generator is dropped it will drop all captured environment\n variables.\n\n### Generators as state machines\n\nIn the compiler, generators are currently compiled as state machines. Each\n`yield` expression will correspond to a different state that stores all live\nvariables over that suspension point. Resumption of a generator will dispatch on\nthe current state and then execute internally until a `yield` is reached, at\nwhich point all state is saved off in the generator and a value is returned.\n\nLet's take a look at an example to see what's going on here:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::Generator;\nuse std::pin::Pin;\n\nfn main() {\n let ret = \"foo\";\n let mut generator = move || {\n yield 1;\n return ret\n };\n\n Pin::new(&mut generator).resume(());\n Pin::new(&mut generator).resume(());\n}\n```\n\nThis generator literal will compile down to something similar to:\n\n```rust\n#![feature(arbitrary_self_types, generators, generator_trait)]\n\nuse std::ops::{Generator, GeneratorState};\nuse std::pin::Pin;\n\nfn main() {\n let ret = \"foo\";\n let mut generator = {\n enum __Generator {\n Start(&'static str),\n Yield1(&'static str),\n Done,\n }\n\n impl Generator for __Generator {\n type Yield = i32;\n type Return = &'static str;\n\n fn resume(mut self: Pin<&mut Self>, resume: ()) -> GeneratorState {\n use std::mem;\n match mem::replace(&mut *self, __Generator::Done) {\n __Generator::Start(s) => {\n *self = __Generator::Yield1(s);\n GeneratorState::Yielded(1)\n }\n\n __Generator::Yield1(s) => {\n *self = __Generator::Done;\n GeneratorState::Complete(s)\n }\n\n __Generator::Done => {\n panic!(\"generator resumed after completion\")\n }\n }\n }\n }\n\n __Generator::Start(ret)\n };\n\n Pin::new(&mut generator).resume(());\n Pin::new(&mut generator).resume(());\n}\n```\n\nNotably here we can see that the compiler is generating a fresh type,\n`__Generator` in this case. This type has a number of states (represented here\nas an `enum`) corresponding to each of the conceptual states of the generator.\nAt the beginning we're closing over our outer variable `foo` and then that\nvariable is also live over the `yield` point, so it's stored in both states.\n\nWhen the generator starts it'll immediately yield 1, but it saves off its state\njust before it does so indicating that it has reached the yield point.

The syntax isn't final, either. We may need an alternative syntax for Rust 2015 because, in Rust 2015, expressions like `[e; dyn(1)]` would be ambiguous. One possible alternative proposed in the RFC is `[e; n]`: if `n` captures one or more local variables, then it is considered as `[e; dyn n]`.\n\n## Advisory on stack usage\n\nIt's advised not to casually use the `#![feature(unsized_locals)]` feature. Typical use-cases are:\n\n- When you need a by-value trait objects.\n- When you really need a fast allocation of small temporary arrays.\n\nAnother pitfall is repetitive allocation and temporaries. Currently the compiler simply extends the stack frame every time it encounters an unsized assignment. So for example, the code\n\n```rust\n#![feature(unsized_locals)]\n\nfn main() {\n let x: Box<[i32]> = Box::new([1, 2, 3, 4, 5]);\n let _x = {{{{{{{{{{*x}}}}}}}}}};\n}\n```\n\nand the code\n\n```rust\n#![feature(unsized_locals)]\n\nfn main() {\n for _ in 0..10 {\n let x: Box<[i32]> = Box::new([1, 2, 3, 4, 5]);\n let _x = *x;\n }\n}\n```\n\nwill unnecessarily extend the stack frame.\n" } , LintCompletion { label : "or_patterns" , description : "# `or_patterns`\n\nThe tracking issue for this feature is: [#54883]\n\n[#54883]: https://github.com/rust-lang/rust/issues/54883\n\n------------------------\n\nThe `or_pattern` language feature allows `|` to be arbitrarily nested within\na pattern, for example, `Some(A(0) | B(1 | 2))` becomes a valid pattern.\n\n## Examples\n\n```rust,ignore\n#![feature(or_patterns)]\n\npub enum Foo {\n Bar,\n Baz,\n Quux,\n}\n\npub fn example(maybe_foo: Option) {\n match maybe_foo {\n Some(Foo::Bar | Foo::Baz) => {\n println!(\"The value contained `Bar` or `Baz`\");\n }\n Some(_) => {\n println!(\"The value did not contain `Bar` or `Baz`\");\n }\n None => {\n println!(\"The value was `None`\");\n }\n }\n}\n```\n" } , LintCompletion { label : "member_constraints" , description : "# `member_constraints`\n\nThe tracking issue for this feature is: [#61997]\n\n[#61997]: https://github.com/rust-lang/rust/issues/61997\n\n------------------------\n\nThe `member_constraints` feature gate lets you use `impl Trait` syntax with\nmultiple unrelated lifetime parameters.\n\nA simple example is:\n\n```rust\n#![feature(member_constraints)]\n\ntrait Trait<'a, 'b> { }\nimpl Trait<'_, '_> for T {}\n\nfn foo<'a, 'b>(x: &'a u32, y: &'b u32) -> impl Trait<'a, 'b> {\n (x, y)\n}\n\nfn main() { }\n```\n\nWithout the `member_constraints` feature gate, the above example is an\nerror because both `'a` and `'b` appear in the impl Trait bounds, but\nneither outlives the other.\n" } , LintCompletion { label : "optin_builtin_traits" , description : "# `optin_builtin_traits`\n\nThe tracking issue for this feature is [#13231] \n\n[#13231]: https://github.com/rust-lang/rust/issues/13231\n\n----\n\nThe `optin_builtin_traits` feature gate allows you to define auto traits.\n\nAuto traits, like [`Send`] or [`Sync`] in the standard library, are marker traits\nthat are automatically implemented for every type, unless the type, or a type it contains, \nhas explicitly opted out via a negative impl.

These automatic impls contain a where clause for each field\nof the form `T: AutoTrait`, where `T` is the type of the field and\n`AutoTrait` is the auto trait in question. As an example, consider the\nstruct `List` and the auto trait `Send`:\n\n```rust\nstruct List {\n data: T,\n next: Option>>,\n}\n```\n\nPresuming that there is no explicit impl of `Send` for `List`, the\ncompiler will supply an automatic impl of the form:\n\n```rust\nstruct List {\n data: T,\n next: Option>>,\n}\n\nunsafe impl Send for List\nwhere\n T: Send, // from the field `data`\n Option>>: Send, // from the field `next`\n{ }\n```\n\nExplicit impls may be either positive or negative. They take the form:\n\n```rust,ignore\nimpl<...> AutoTrait for StructName<..> { }\nimpl<...> !AutoTrait for StructName<..> { }\n```\n\n## Coinduction: Auto traits permit cyclic matching\n\nUnlike ordinary trait matching, auto traits are **coinductive**. This\nmeans, in short, that cycles which occur in trait matching are\nconsidered ok. As an example, consider the recursive struct `List`\nintroduced in the previous section. In attempting to determine whether\n`List: Send`, we would wind up in a cycle: to apply the impl, we must\nshow that `Option>: Send`, which will in turn require\n`Box: Send` and then finally `List: Send` again. Under ordinary\ntrait matching, this cycle would be an error, but for an auto trait it\nis considered a successful match.\n\n## Items\n\nAuto traits cannot have any trait items, such as methods or associated types. This ensures that we can generate default implementations.\n\n## Supertraits\n\nAuto traits cannot have supertraits.

The marker is the attribute `#[lang = \"...\"]` and there are\nvarious different values of `...`, i.e. various different 'lang\nitems'.\n\nFor example, `Box` pointers require two lang items, one for allocation\nand one for deallocation. A freestanding program that uses the `Box`\nsugar for dynamic allocations via `malloc` and `free`:\n\n```rust,ignore\n#![feature(lang_items, box_syntax, start, libc, core_intrinsics)]\n#![no_std]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\nextern crate libc;\n\n#[lang = \"owned_box\"]\npub struct Box(*mut T);\n\n#[lang = \"exchange_malloc\"]\nunsafe fn allocate(size: usize, _align: usize) -> *mut u8 {\n let p = libc::malloc(size as libc::size_t) as *mut u8;\n\n // Check if `malloc` failed:\n if p as usize == 0 {\n intrinsics::abort();\n }\n\n p\n}\n\n#[lang = \"box_free\"]\nunsafe fn box_free(ptr: *mut T) {\n libc::free(ptr as *mut libc::c_void)\n}\n\n#[start]\nfn main(_argc: isize, _argv: *const *const u8) -> isize {\n let _x = box 1;\n\n 0\n}\n\n#[lang = \"eh_personality\"] extern fn rust_eh_personality() {}\n#[lang = \"panic_impl\"] extern fn rust_begin_panic(info: &PanicInfo) -> ! { unsafe { intrinsics::abort() } }\n#[no_mangle] pub extern fn rust_eh_register_frames () {}\n#[no_mangle] pub extern fn rust_eh_unregister_frames () {}\n```\n\nNote the use of `abort`: the `exchange_malloc` lang item is assumed to\nreturn a valid pointer, and so needs to do the check internally.\n\nOther features provided by lang items include:\n\n- overloadable operators via traits: the traits corresponding to the\n `==`, `<`, dereferencing (`*`) and `+` (etc.) operators are all\n marked with lang items; those specific four are `eq`, `ord`,\n `deref`, and `add` respectively.\n- stack unwinding and general failure; the `eh_personality`,\n `panic` and `panic_bounds_checks` lang items.\n- the traits in `std::marker` used to indicate types of\n various kinds; lang items `send`, `sync` and `copy`.\n- the marker types and variance indicators found in\n `std::marker`; lang items `covariant_type`,\n `contravariant_lifetime`, etc.\n\nLang items are loaded lazily by the compiler; e.g. if one never uses\n`Box` then there is no need to define functions for `exchange_malloc`\nand `box_free`. `rustc` will emit an error when an item is needed\nbut not found in the current crate or any that it depends on.\n\nMost lang items are defined by `libcore`, but if you're trying to build\nan executable without the standard library, you'll run into the need\nfor lang items. The rest of this page focuses on this use-case, even though\nlang items are a bit broader than that.\n\n### Using libc\n\nIn order to build a `#[no_std]` executable we will need libc as a dependency.\nWe can specify this using our `Cargo.toml` file:\n\n```toml\n[dependencies]\nlibc = { version = \"0.2.14\", default-features = false }\n```\n\nNote that the default features have been disabled. This is a critical step -\n**the default features of libc include the standard library and so must be\ndisabled.**\n\n### Writing an executable without stdlib\n\nControlling the entry point is possible in two ways: the `#[start]` attribute,\nor overriding the default shim for the C `main` function with your own.\n\nThe function marked `#[start]` is passed the command line parameters\nin the same format as C:\n\n```rust,ignore\n#![feature(lang_items, core_intrinsics)]\n#![feature(start)]\n#![no_std]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\n// Pull in the system libc library for what crt0.o likely requires.\nextern crate libc;\n\n// Entry point for this program.\n#[start]\nfn start(_argc: isize, _argv: *const *const u8) -> isize {\n 0\n}\n\n// These functions are used by the compiler, but not\n// for a bare-bones hello world. These are normally\n// provided by libstd.\n#[lang = \"eh_personality\"]\n#[no_mangle]\npub extern fn rust_eh_personality() {\n}\n\n#[lang = \"panic_impl\"]\n#[no_mangle]\npub extern fn rust_begin_panic(info: &PanicInfo) -> ! {\n unsafe { intrinsics::abort() }\n}\n```\n\nTo override the compiler-inserted `main` shim, one has to disable it\nwith `#![no_main]` and then create the appropriate symbol with the\ncorrect ABI and the correct name, which requires overriding the\ncompiler's name mangling too:\n\n```rust,ignore\n#![feature(lang_items, core_intrinsics)]\n#![feature(start)]\n#![no_std]\n#![no_main]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\n// Pull in the system libc library for what crt0.o likely requires.\nextern crate libc;\n\n// Entry point for this program.\n#[no_mangle] // ensure that this symbol is called `main` in the output\npub extern fn main(_argc: i32, _argv: *const *const u8) -> i32 {\n 0\n}\n\n// These functions are used by the compiler, but not\n// for a bare-bones hello world.

You may observe this via linker error messages\nsuch as \"```undefined reference to `__rust_probestack'```\".\n\n## More about the language items\n\nThe compiler currently makes a few assumptions about symbols which are\navailable in the executable to call. Normally these functions are provided by\nthe standard library, but without it you must define your own. These symbols\nare called \"language items\", and they each have an internal name, and then a\nsignature that an implementation must conform to.\n\nThe first of these functions, `rust_eh_personality`, is used by the failure\nmechanisms of the compiler. This is often mapped to GCC's personality function\n(see the [libstd implementation][unwind] for more information), but crates\nwhich do not trigger a panic can be assured that this function is never\ncalled.

Negative impls are a commitment not to implement the given trait for the named types.\n\n## Orphan and overlap rules\n\nNegative impls must obey the same orphan rules as a positive impl. This implies you cannot add a negative impl for types defined in upstream crates and so forth.\n\nSimilarly, negative impls cannot overlap with positive impls, again using the same \"overlap\" check that we ordinarily use to determine if two impls overlap. (Note that positive impls typically cannot overlap with one another either, except as permitted by specialization.)\n\n## Interaction with auto traits\n\nDeclaring a negative impl `impl !SomeAutoTrait for SomeType` for an\nauto-trait serves two purposes:\n\n* as with any trait, it declares that `SomeType` will never implement `SomeAutoTrait`;\n* it disables the automatic `SomeType: SomeAutoTrait` impl that would otherwise have been generated.\n\nNote that, at present, there is no way to indicate that a given type\ndoes not implement an auto trait *but that it may do so in the\nfuture*. For ordinary types, this is done by simply not declaring any\nimpl at all, but that is not an option for auto traits. A workaround\nis that one could embed a marker type as one of the fields, where the\nmarker type is `!AutoTrait`.\n\n## Immediate uses\n\nNegative impls are used to declare that `&T: !DerefMut` and `&mut T: !Clone`, as required to fix the soundness of `Pin` described in [#66544](https://github.com/rust-lang/rust/issues/66544).\n\nThis serves two purposes:\n\n* For proving the correctness of unsafe code, we can use that impl as evidence that no `DerefMut` or `Clone` impl exists.\n* It prevents downstream crates from creating such impls.\n" } , LintCompletion { label : "abi_ptx" , description : "# `abi_ptx`\n\nThe tracking issue for this feature is: [#38788]\n\n[#38788]: https://github.com/rust-lang/rust/issues/38788\n\n------------------------\n\nWhen emitting PTX code, all vanilla Rust functions (`fn`) get translated to\n\"device\" functions.

This is\ngenerally unwanted unless you are building another plugin.\n\nThe usual practice is to put compiler plugins in their own crate, separate from\nany `macro_rules!` macros or ordinary Rust code meant to be used by consumers\nof a library.\n\n# Lint plugins\n\nPlugins can extend [Rust's lint\ninfrastructure](../../reference/attributes/diagnostics.md#lint-check-attributes) with\nadditional checks for code style, safety, etc. Now let's write a plugin\n[`lint-plugin-test.rs`](https://github.com/rust-lang/rust/blob/master/src/test/ui-fulldeps/auxiliary/lint-plugin-test.rs)\nthat warns about any item named `lintme`.\n\n```rust,ignore\n#![feature(plugin_registrar)]\n#![feature(box_syntax, rustc_private)]\n\nextern crate rustc_ast;\n\n// Load rustc as a plugin to get macros\nextern crate rustc_driver;\n#[macro_use]\nextern crate rustc_lint;\n#[macro_use]\nextern crate rustc_session;\n\nuse rustc_driver::plugin::Registry;\nuse rustc_lint::{EarlyContext, EarlyLintPass, LintArray, LintContext, LintPass};\nuse rustc_ast::ast;\ndeclare_lint!(TEST_LINT, Warn, \"Warn about items named 'lintme'\");\n\ndeclare_lint_pass!(Pass => [TEST_LINT]);\n\nimpl EarlyLintPass for Pass {\n fn check_item(&mut self, cx: &EarlyContext, it: &ast::Item) {\n if it.ident.name.as_str() == \"lintme\" {\n cx.lint(TEST_LINT, |lint| {\n lint.build(\"item is named 'lintme'\").set_span(it.span).emit()\n });\n }\n }\n}\n\n#[plugin_registrar]\npub fn plugin_registrar(reg: &mut Registry) {\n reg.lint_store.register_lints(&[&TEST_LINT]);\n reg.lint_store.register_early_pass(|| box Pass);\n}\n```\n\nThen code like\n\n```rust,ignore\n#![feature(plugin)]\n#![plugin(lint_plugin_test)]\n\nfn lintme() { }\n```\n\nwill produce a compiler warning:\n\n```txt\nfoo.rs:4:1: 4:16 warning: item is named 'lintme', #[warn(test_lint)] on by default\nfoo.rs:4 fn lintme() { }\n ^~~~~~~~~~~~~~~\n```\n\nThe components of a lint plugin are:\n\n* one or more `declare_lint!` invocations, which define static `Lint` structs;\n\n* a struct holding any state needed by the lint pass (here, none);\n\n* a `LintPass`\n implementation defining how to check each syntax element. A single\n `LintPass` may call `span_lint` for several different `Lint`s, but should\n register them all through the `get_lints` method.\n\nLint passes are syntax traversals, but they run at a late stage of compilation\nwhere type information is available. `rustc`'s [built-in\nlints](https://github.com/rust-lang/rust/blob/master/src/librustc_session/lint/builtin.rs)\nmostly use the same infrastructure as lint plugins, and provide examples of how\nto access type information.\n\nLints defined by plugins are controlled by the usual [attributes and compiler\nflags](../../reference/attributes/diagnostics.md#lint-check-attributes), e.g.\n`#[allow(test_lint)]` or `-A test-lint`. These identifiers are derived from the\nfirst argument to `declare_lint!`, with appropriate case and punctuation\nconversion.\n\nYou can run `rustc -W help foo.rs` to see a list of lints known to `rustc`,\nincluding those provided by plugins loaded by `foo.rs`.\n" } , LintCompletion { label : "concat_idents" , description : "# `concat_idents`\n\nThe tracking issue for this feature is: [#29599]\n\n[#29599]: https://github.com/rust-lang/rust/issues/29599\n\n------------------------\n\nThe `concat_idents` feature adds a macro for concatenating multiple identifiers\ninto one identifier.\n\n## Examples\n\n```rust\n#![feature(concat_idents)]\n\nfn main() {\n fn foobar() -> u32 { 23 }\n let f = concat_idents!(foo, bar);\n assert_eq!(f(), 23);\n}\n```" } , LintCompletion { label : "update_panic_count" , description : "# `update_panic_count`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "fn_traits" , description : "# `fn_traits`\n\nThe tracking issue for this feature is [#29625]\n\nSee Also: [`unboxed_closures`](../language-features/unboxed-closures.md)\n\n[#29625]: https://github.com/rust-lang/rust/issues/29625\n\n----\n\nThe `fn_traits` feature allows for implementation of the [`Fn*`] traits\nfor creating custom closure-like types.\n\n[`Fn*`]: https://doc.rust-lang.org/std/ops/trait.Fn.html\n\n```rust\n#![feature(unboxed_closures)]\n#![feature(fn_traits)]\n\nstruct Adder {\n a: u32\n}\n\nimpl FnOnce<(u32, )> for Adder {\n type Output = u32;\n extern \"rust-call\" fn call_once(self, b: (u32, )) -> Self::Output {\n self.a + b.0\n }\n}\n\nfn main() {\n let adder = Adder { a: 3 };\n assert_eq!(adder(2), 5);\n}\n```\n" } , LintCompletion { label : "try_trait" , description : "# `try_trait`\n\nThe tracking issue for this feature is: [#42327]\n\n[#42327]: https://github.com/rust-lang/rust/issues/42327\n\n------------------------\n\nThis introduces a new trait `Try` for extending the `?` operator to types\nother than `Result` (a part of [RFC 1859]).

The macro is a no-frills\ninterface to LLVM's concept of [module-level inline assembly]. That is,\nall caveats applicable to LLVM's module-level inline assembly apply\nto `global_asm!`.\n\n[module-level inline assembly]: http://llvm.org/docs/LangRef.html#module-level-inline-assembly\n\n`global_asm!` fills a role not currently satisfied by either `asm!`\nor `#[naked]` functions. The programmer has _all_ features of the\nassembler at their disposal. The linker will expect to resolve any\nsymbols defined in the inline assembly, modulo any symbols marked as\nexternal. It also means syntax for directives and assembly follow the\nconventions of the assembler in your toolchain.\n\nA simple usage looks like this:\n\n```rust,ignore\n# #![feature(global_asm)]\n# you also need relevant target_arch cfgs\nglobal_asm!(include_str!(\"something_neato.s\"));\n```\n\nAnd a more complicated usage looks like this:\n\n```rust,ignore\n# #![feature(global_asm)]\n# #![cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n\npub mod sally {\n global_asm!(r#\"\n .global foo\n foo:\n jmp baz\n \"#);\n\n #[no_mangle]\n pub unsafe extern \"C\" fn baz() {}\n}\n\n// the symbols `foo` and `bar` are global, no matter where\n// `global_asm!` was used.\nextern \"C\" {\n fn foo();\n fn bar();\n}\n\npub mod harry {\n global_asm!(r#\"\n .global bar\n bar:\n jmp quux\n \"#);\n\n #[no_mangle]\n pub unsafe extern \"C\" fn quux() {}\n}\n```\n\nYou may use `global_asm!` multiple times, anywhere in your crate, in\nwhatever way suits you. The effect is as if you concatenated all\nusages and placed the larger, single usage in the crate root.\n\n------------------------\n\nIf you don't need quite as much power and flexibility as\n`global_asm!` provides, and you don't mind restricting your inline\nassembly to `fn` bodies only, you might try the\n[asm](asm.md) feature instead.\n" } , LintCompletion { label : "sort_internals" , description : "# `sort_internals`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "test" , description : "# `test`\n\nThe tracking issue for this feature is: None.\n\n------------------------\n\nThe internals of the `test` crate are unstable, behind the `test` flag. The\nmost widely used part of the `test` crate are benchmark tests, which can test\nthe performance of your code. Let's make our `src/lib.rs` look like this\n(comments elided):\n\n```rust,ignore\n#![feature(test)]\n\nextern crate test;\n\npub fn add_two(a: i32) -> i32 {\n a + 2\n}\n\n#[cfg(test)]\nmod tests {\n use super::*;\n use test::Bencher;\n\n #[test]\n fn it_works() {\n assert_eq!(4, add_two(2));\n }\n\n #[bench]\n fn bench_add_two(b: &mut Bencher) {\n b.iter(|| add_two(2));\n }\n}\n```\n\nNote the `test` feature gate, which enables this unstable feature.\n\nWe've imported the `test` crate, which contains our benchmarking support.\nWe have a new function as well, with the `bench` attribute. Unlike regular\ntests, which take no arguments, benchmark tests take a `&mut Bencher`. This\n`Bencher` provides an `iter` method, which takes a closure. This closure\ncontains the code we'd like to benchmark.\n\nWe can run benchmark tests with `cargo bench`:\n\n```bash\n$ cargo bench\n Compiling adder v0.0.1 (file:///home/steve/tmp/adder)\n Running target/release/adder-91b3e234d4ed382a\n\nrunning 2 tests\ntest tests::it_works ... ignored\ntest tests::bench_add_two ... bench: 1 ns/iter (+/- 0)\n\ntest result: ok. 0 passed; 0 failed; 1 ignored; 1 measured\n```\n\nOur non-benchmark test was ignored. You may have noticed that `cargo bench`\ntakes a bit longer than `cargo test`. This is because Rust runs our benchmark\na number of times, and then takes the average. Because we're doing so little\nwork in this example, we have a `1 ns/iter (+/- 0)`, but this would show\nthe variance if there was one.\n\nAdvice on writing benchmarks:\n\n\n* Move setup code outside the `iter` loop; only put the part you want to measure inside\n* Make the code do \"the same thing\" on each iteration; do not accumulate or change state\n* Make the outer function idempotent too; the benchmark runner is likely to run\n it many times\n* Make the inner `iter` loop short and fast so benchmark runs are fast and the\n calibrator can adjust the run-length at fine resolution\n* Make the code in the `iter` loop do something simple, to assist in pinpointing\n performance improvements (or regressions)\n\n## Gotcha: optimizations\n\nThere's another tricky part to writing benchmarks: benchmarks compiled with\noptimizations activated can be dramatically changed by the optimizer so that\nthe benchmark is no longer benchmarking what one expects. For example, the\ncompiler might recognize that some calculation has no external effects and\nremove it entirely.\n\n```rust,ignore\n#![feature(test)]\n\nextern crate test;\nuse test::Bencher;\n\n#[bench]\nfn bench_xor_1000_ints(b: &mut Bencher) {\n b.iter(|| {\n (0..1000).fold(0, |old, new| old ^ new);\n });\n}\n```\n\ngives the following results\n\n```text\nrunning 1 test\ntest bench_xor_1000_ints ... bench: 0 ns/iter (+/- 0)\n\ntest result: ok. 0 passed; 0 failed; 0 ignored; 1 measured\n```\n\nThe benchmarking runner offers two ways to avoid this. Either, the closure that\nthe `iter` method receives can return an arbitrary value which forces the\noptimizer to consider the result used and ensures it cannot remove the\ncomputation entirely. This could be done for the example above by adjusting the\n`b.iter` call to\n\n```rust\n# struct X;\n# impl X { fn iter(&self, _: F) where F: FnMut() -> T {} } let b = X;\nb.iter(|| {\n // Note lack of `;` (could also use an explicit `return`).\n (0..1000).fold(0, |old, new| old ^ new)\n});\n```\n\nOr, the other option is to call the generic `test::black_box` function, which\nis an opaque \"black box\" to the optimizer and so forces it to consider any\nargument as used.\n\n```rust\n#![feature(test)]\n\nextern crate test;\n\n# fn main() {\n# struct X;\n# impl X { fn iter(&self, _: F) where F: FnMut() -> T {} } let b = X;\nb.iter(|| {\n let n = test::black_box(1000);\n\n (0..n).fold(0, |a, b| a ^ b)\n})\n# }\n```\n\nNeither of these read or modify the value, and are very cheap for small values.\nLarger values can be passed indirectly to reduce overhead (e.g.\n`black_box(&huge_struct)`).\n\nPerforming either of the above changes gives the following benchmarking results\n\n```text\nrunning 1 test\ntest bench_xor_1000_ints ... bench: 131 ns/iter (+/- 3)\n\ntest result: ok. 0 passed; 0 failed; 0 ignored; 1 measured\n```\n\nHowever, the optimizer can still modify a testcase in an undesirable manner\neven when using either of the above.\n" } , LintCompletion { label : "windows_stdio" , description : "# `windows_stdio`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "allocator_api" , description : "# `allocator_api`\n\nThe tracking issue for this feature is [#32838]\n\n[#32838]: https://github.com/rust-lang/rust/issues/32838\n\n------------------------\n\nSometimes you want the memory for one collection to use a different\nallocator than the memory for another collection.

Rust supports using inline\nassembly to do this via the `asm!` macro.\n\n# Guide-level explanation\n[guide-level-explanation]: #guide-level-explanation\n\nRust provides support for inline assembly via the `asm!` macro.\nIt can be used to embed handwritten assembly in the assembly output generated by the compiler.\nGenerally this should not be necessary, but might be where the required performance or timing\ncannot be otherwise achieved. Accessing low level hardware primitives, e.g. in kernel code, may also demand this functionality.\n\n> **Note**: the examples here are given in x86/x86-64 assembly, but ARM, AArch64 and RISC-V are also supported.\n\n## Basic usage\n\nLet us start with the simplest possible example:\n\n```rust,allow_fail\n# #![feature(asm)]\nunsafe {\n asm!(\"nop\");\n}\n```\n\nThis will insert a NOP (no operation) instruction into the assembly generated by the compiler.\nNote that all `asm!` invocations have to be inside an `unsafe` block, as they could insert\narbitrary instructions and break various invariants. The instructions to be inserted are listed\nin the first argument of the `asm!` macro as a string literal.\n\n## Inputs and outputs\n\nNow inserting an instruction that does nothing is rather boring. Let us do something that\nactually acts on data:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet x: u64;\nunsafe {\n asm!(\"mov {}, 5\", out(reg) x);\n}\nassert_eq!(x, 5);\n```\n\nThis will write the value `5` into the `u64` variable `x`.\nYou can see that the string literal we use to specify instructions is actually a template string.\nIt is governed by the same rules as Rust [format strings][format-syntax].\nThe arguments that are inserted into the template however look a bit different then you may\nbe familiar with. First we need to specify if the variable is an input or an output of the\ninline assembly. In this case it is an output. We declared this by writing `out`.\nWe also need to specify in what kind of register the assembly expects the variable.\nIn this case we put it in an arbitrary general purpose register by specifying `reg`.\nThe compiler will choose an appropriate register to insert into\nthe template and will read the variable from there after the inline assembly finishes executing.\n\nLet us see another example that also uses an input:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet i: u64 = 3;\nlet o: u64;\nunsafe {\n asm!(\n \"mov {0}, {1}\",\n \"add {0}, {number}\",\n out(reg) o,\n in(reg) i,\n number = const 5,\n );\n}\nassert_eq!(o, 8);\n```\n\nThis will add `5` to the input in variable `i` and write the result to variable `o`.\nThe particular way this assembly does this is first copying the value from `i` to the output,\nand then adding `5` to it.\n\nThe example shows a few things:\n\nFirst, we can see that `asm!` allows multiple template string arguments; each\none is treated as a separate line of assembly code, as if they were all joined\ntogether with newlines between them. This makes it easy to format assembly\ncode.\n\nSecond, we can see that inputs are declared by writing `in` instead of `out`.\n\nThird, one of our operands has a type we haven't seen yet, `const`.\nThis tells the compiler to expand this argument to value directly inside the assembly template.\nThis is only possible for constants and literals.\n\nFourth, we can see that we can specify an argument number, or name as in any format string.\nFor inline assembly templates this is particularly useful as arguments are often used more than once.\nFor more complex inline assembly using this facility is generally recommended, as it improves\nreadability, and allows reordering instructions without changing the argument order.\n\nWe can further refine the above example to avoid the `mov` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut x: u64 = 3;\nunsafe {\n asm!(\"add {0}, {number}\", inout(reg) x, number = const 5);\n}\nassert_eq!(x, 8);\n```\n\nWe can see that `inout` is used to specify an argument that is both input and output.\nThis is different from specifying an input and output separately in that it is guaranteed to assign both to the same register.\n\nIt is also possible to specify different variables for the input and output parts of an `inout` operand:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet x: u64 = 3;\nlet y: u64;\nunsafe {\n asm!(\"add {0}, {number}\", inout(reg) x => y, number = const 5);\n}\nassert_eq!(y, 8);\n```\n\n## Late output operands\n\nThe Rust compiler is conservative with its allocation of operands. It is assumed that an `out`\ncan be written at any time, and can therefore not share its location with any other argument.\nHowever, to guarantee optimal performance it is important to use as few registers as possible,\nso they won't have to be saved and reloaded around the inline assembly block.\nTo achieve this Rust provides a `lateout` specifier. This can be used on any output that is\nwritten only after all inputs have been consumed.\nThere is also a `inlateout` variant of this specifier.\n\nHere is an example where `inlateout` *cannot* be used:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nlet c: u64 = 4;\nunsafe {\n asm!(\n \"add {0}, {1}\",\n \"add {0}, {2}\",\n inout(reg) a,\n in(reg) b,\n in(reg) c,\n );\n}\nassert_eq!(a, 12);\n```\n\nHere the compiler is free to allocate the same register for inputs `b` and `c` since it knows they have the same value. However it must allocate a separate register for `a` since it uses `inout` and not `inlateout`. If `inlateout` was used, then `a` and `c` could be allocated to the same register, in which case the first instruction to overwrite the value of `c` and cause the assembly code to produce the wrong result.\n\nHowever the following example can use `inlateout` since the output is only modified after all input registers have been read:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nunsafe {\n asm!(\"add {0}, {1}\", inlateout(reg) a, in(reg) b);\n}\nassert_eq!(a, 8);\n```\n\nAs you can see, this assembly fragment will still work correctly if `a` and `b` are assigned to the same register.\n\n## Explicit register operands\n\nSome instructions require that the operands be in a specific register.\nTherefore, Rust inline assembly provides some more specific constraint specifiers.\nWhile `reg` is generally available on any architecture, these are highly architecture specific. E.g. for x86 the general purpose registers `eax`, `ebx`, `ecx`, `edx`, `ebp`, `esi`, and `edi`\namong others can be addressed by their name.\n\n```rust,allow_fail,no_run\n# #![feature(asm)]\nlet cmd = 0xd1;\nunsafe {\n asm!(\"out 0x64, eax\", in(\"eax\") cmd);\n}\n```\n\nIn this example we call the `out` instruction to output the content of the `cmd` variable\nto port `0x64`. Since the `out` instruction only accepts `eax` (and its sub registers) as operand\nwe had to use the `eax` constraint specifier.\n\nNote that unlike other operand types, explicit register operands cannot be used in the template string: you can't use `{}` and should write the register name directly instead. Also, they must appear at the end of the operand list after all other operand types.\n\nConsider this example which uses the x86 `mul` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nfn mul(a: u64, b: u64) -> u128 {\n let lo: u64;\n let hi: u64;\n\n unsafe {\n asm!(\n // The x86 mul instruction takes rax as an implicit input and writes\n // the 128-bit result of the multiplication to rax:rdx.\n \"mul {}\",\n in(reg) a,\n inlateout(\"rax\") b => lo,\n lateout(\"rdx\") hi\n );\n }\n\n ((hi as u128) << 64) + lo as u128\n}\n```\n\nThis uses the `mul` instruction to multiply two 64-bit inputs with a 128-bit result.\nThe only explicit operand is a register, that we fill from the variable `a`.\nThe second operand is implicit, and must be the `rax` register, which we fill from the variable `b`.\nThe lower 64 bits of the result are stored in `rax` from which we fill the variable `lo`.\nThe higher 64 bits are stored in `rdx` from which we fill the variable `hi`.\n\n## Clobbered registers\n\nIn many cases inline assembly will modify state that is not needed as an output.\nUsually this is either because we have to use a scratch register in the assembly,\nor instructions modify state that we don't need to further examine.\nThis state is generally referred to as being \"clobbered\".\nWe need to tell the compiler about this since it may need to save and restore this state\naround the inline assembly block.\n\n```rust,allow_fail\n# #![feature(asm)]\nlet ebx: u32;\nlet ecx: u32;\n\nunsafe {\n asm!(\n \"cpuid\",\n // EAX 4 selects the \"Deterministic Cache Parameters\" CPUID leaf\n inout(\"eax\") 4 => _,\n // ECX 0 selects the L0 cache information.\n inout(\"ecx\") 0 => ecx,\n lateout(\"ebx\") ebx,\n lateout(\"edx\") _,\n );\n}\n\nprintln!(\n \"L1 Cache: {}\",\n ((ebx >> 22) + 1) * (((ebx >> 12) & 0x3ff) + 1) * ((ebx & 0xfff) + 1) * (ecx + 1)\n);\n```\n\nIn the example above we use the `cpuid` instruction to get the L1 cache size.\nThis instruction writes to `eax`, `ebx`, `ecx`, and `edx`, but for the cache size we only care about the contents of `ebx` and `ecx`.\n\nHowever we still need to tell the compiler that `eax` and `edx` have been modified so that it can save any values that were in these registers before the asm. This is done by declaring these as outputs but with `_` instead of a variable name, which indicates that the output value is to be discarded.\n\nThis can also be used with a general register class (e.g. `reg`) to obtain a scratch register for use inside the asm code:\n\n```rust,allow_fail\n# #![feature(asm)]\n// Multiply x by 6 using shifts and adds\nlet mut x: u64 = 4;\nunsafe {\n asm!(\n \"mov {tmp}, {x}\",\n \"shl {tmp}, 1\",\n \"shl {x}, 2\",\n \"add {x}, {tmp}\",\n x = inout(reg) x,\n tmp = out(reg) _,\n );\n}\nassert_eq!(x, 4 * 6);\n```\n\n## Symbol operands\n\nA special operand type, `sym`, allows you to use the symbol name of a `fn` or `static` in inline assembly code.\nThis allows you to call a function or access a global variable without needing to keep its address in a register.\n\n```rust,allow_fail\n# #![feature(asm)]\nextern \"C\" fn foo(arg: i32) {\n println!(\"arg = {}\", arg);\n}\n\nfn call_foo(arg: i32) {\n unsafe {\n asm!(\n \"call {}\",\n sym foo,\n // 1st argument in rdi, which is caller-saved\n inout(\"rdi\") arg => _,\n // All caller-saved registers must be marked as clobberred\n out(\"rax\") _, out(\"rcx\") _, out(\"rdx\") _, out(\"rsi\") _,\n out(\"r8\") _, out(\"r9\") _, out(\"r10\") _, out(\"r11\") _,\n out(\"xmm0\") _, out(\"xmm1\") _, out(\"xmm2\") _, out(\"xmm3\") _,\n out(\"xmm4\") _, out(\"xmm5\") _, out(\"xmm6\") _, out(\"xmm7\") _,\n out(\"xmm8\") _, out(\"xmm9\") _, out(\"xmm10\") _, out(\"xmm11\") _,\n out(\"xmm12\") _, out(\"xmm13\") _, out(\"xmm14\") _, out(\"xmm15\") _,\n )\n }\n}\n```\n\nNote that the `fn` or `static` item does not need to be public or `#[no_mangle]`:\nthe compiler will automatically insert the appropriate mangled symbol name into the assembly code.\n\n## Register template modifiers\n\nIn some cases, fine control is needed over the way a register name is formatted when inserted into the template string. This is needed when an architecture's assembly language has several names for the same register, each typically being a \"view\" over a subset of the register (e.g. the low 32 bits of a 64-bit register).\n\nBy default the compiler will always choose the name that refers to the full register size (e.g. `rax` on x86-64, `eax` on x86, etc).\n\nThis default can be overriden by using modifiers on the template string operands, just like you would with format strings:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut x: u16 = 0xab;\n\nunsafe {\n asm!(\"mov {0:h}, {0:l}\", inout(reg_abcd) x);\n}\n\nassert_eq!(x, 0xabab);\n```\n\nIn this example, we use the `reg_abcd` register class to restrict the register allocator to the 4 legacy x86 register (`ax`, `bx`, `cx`, `dx`) of which the first two bytes can be addressed independently.\n\nLet us assume that the register allocator has chosen to allocate `x` in the `ax` register.\nThe `h` modifier will emit the register name for the high byte of that register and the `l` modifier will emit the register name for the low byte. The asm code will therefore be expanded as `mov ah, al` which copies the low byte of the value into the high byte.\n\nIf you use a smaller data type (e.g. `u16`) with an operand and forget the use template modifiers, the compiler will emit a warning and suggest the correct modifier to use.\n\n## Options\n\nBy default, an inline assembly block is treated the same way as an external FFI function call with a custom calling convention: it may read/write memory, have observable side effects, etc. However in many cases, it is desirable to give the compiler more information about what the assembly code is actually doing so that it can optimize better.\n\nLet's take our previous example of an `add` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nunsafe {\n asm!(\n \"add {0}, {1}\",\n inlateout(reg) a, in(reg) b,\n options(pure, nomem, nostack),\n );\n}\nassert_eq!(a, 8);\n```\n\nOptions can be provided as an optional final argument to the `asm!` macro. We specified three options here:\n- `pure` means that the asm code has no observable side effects and that its output depends only on its inputs. This allows the compiler optimizer to call the inline asm fewer times or even eliminate it entirely.\n- `nomem` means that the asm code does not read or write to memory. By default the compiler will assume that inline assembly can read or write any memory address that is accessible to it (e.g. through a pointer passed as an operand, or a global).\n- `nostack` means that the asm code does not push any data onto the stack. This allows the compiler to use optimizations such as the stack red zone on x86-64 to avoid stack pointer adjustments.\n\nThese allow the compiler to better optimize code using `asm!`, for example by eliminating pure `asm!` blocks whose outputs are not needed.\n\nSee the reference for the full list of available options and their effects.\n\n# Reference-level explanation\n[reference-level-explanation]: #reference-level-explanation\n\nInline assembler is implemented as an unsafe macro `asm!()`.\nThe first argument to this macro is a template string literal used to build the final assembly.\nThe following arguments specify input and output operands.\nWhen required, options are specified as the final argument.\n\nThe following ABNF specifies the general syntax:\n\n```ignore\ndir_spec := \"in\" / \"out\" / \"lateout\" / \"inout\" / \"inlateout\"\nreg_spec := / \"\"\noperand_expr := expr / \"_\" / expr \"=>\" expr / expr \"=>\" \"_\"\nreg_operand := dir_spec \"(\" reg_spec \")\" operand_expr\noperand := reg_operand / \"const\" const_expr / \"sym\" path\noption := \"pure\" / \"nomem\" / \"readonly\" / \"preserves_flags\" / \"noreturn\" / \"att_syntax\"\noptions := \"options(\" option *[\",\" option] [\",\"] \")\"\nasm := \"asm!(\" format_string *(\",\" format_string) *(\",\" [ident \"=\"] operand) [\",\" options] [\",\"] \")\"\n```\n\nThe macro will initially be supported only on ARM, AArch64, Hexagon, x86, x86-64 and RISC-V targets. Support for more targets may be added in the future. The compiler will emit an error if `asm!` is used on an unsupported target.\n\n[format-syntax]: https://doc.rust-lang.org/std/fmt/#syntax\n\n## Template string arguments\n\nThe assembler template uses the same syntax as [format strings][format-syntax] (i.e. placeholders are specified by curly braces). The corresponding arguments are accessed in order, by index, or by name. However, implicit named arguments (introduced by [RFC #2795][rfc-2795]) are not supported.\n\nAn `asm!` invocation may have one or more template string arguments; an `asm!` with multiple template string arguments is treated as if all the strings were concatenated with a `\\n` between them. The expected usage is for each template string argument to correspond to a line of assembly code. All template string arguments must appear before any other arguments.\n\nAs with format strings, named arguments must appear after positional arguments. Explicit register operands must appear at the end of the operand list, after named arguments if any.\n\nExplicit register operands cannot be used by placeholders in the template string. All other named and positional operands must appear at least once in the template string, otherwise a compiler error is generated.\n\nThe exact assembly code syntax is target-specific and opaque to the compiler except for the way operands are substituted into the template string to form the code passed to the assembler.\n\nThe 5 targets specified in this RFC (x86, ARM, AArch64, RISC-V, Hexagon) all use the assembly code syntax of the GNU assembler (GAS). On x86, the `.intel_syntax noprefix` mode of GAS is used by default. On ARM, the `.syntax unified` mode is used. These targets impose an additional restriction on the assembly code: any assembler state (e.g. the current section which can be changed with `.section`) must be restored to its original value at the end of the asm string. Assembly code that does not conform to the GAS syntax will result in assembler-specific behavior.\n\n[rfc-2795]: https://github.com/rust-lang/rfcs/pull/2795\n\n## Operand type\n\nSeveral types of operands are supported:\n\n* `in() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain the value of `` at the start of the asm code.\n - The allocated register must contain the same value at the end of the asm code (except if a `lateout` is allocated to the same register).\n* `out() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain an undefined value at the start of the asm code.\n - `` must be a (possibly uninitialized) place expression, to which the contents of the allocated register is written to at the end of the asm code.\n - An underscore (`_`) may be specified instead of an expression, which will cause the contents of the register to be discarded at the end of the asm code (effectively acting as a clobber).\n* `lateout() `\n - Identical to `out` except that the register allocator can reuse a register allocated to an `in`.\n - You should only write to the register after all inputs are read, otherwise you may clobber an input.\n* `inout() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain the value of `` at the start of the asm code.\n - `` must be a mutable initialized place expression, to which the contents of the allocated register is written to at the end of the asm code.\n* `inout() => `\n - Same as `inout` except that the initial value of the register is taken from the value of ``.\n - `` must be a (possibly uninitialized) place expression, to which the contents of the allocated register is written to at the end of the asm code.\n - An underscore (`_`) may be specified instead of an expression for ``, which will cause the contents of the register to be discarded at the end of the asm code (effectively acting as a clobber).\n - `` and `` may have different types.\n* `inlateout() ` / `inlateout() => `\n - Identical to `inout` except that the register allocator can reuse a register allocated to an `in` (this can happen if the compiler knows the `in` has the same initial value as the `inlateout`).\n - You should only write to the register after all inputs are read, otherwise you may clobber an input.\n* `const `\n - `` must be an integer or floating-point constant expression.\n - The value of the expression is formatted as a string and substituted directly into the asm template string.\n* `sym `\n - `` must refer to a `fn` or `static`.\n - A mangled symbol name referring to the item is substituted into the asm template string.\n - The substituted string does not include any modifiers (e.g. GOT, PLT, relocations, etc).\n - `` is allowed to point to a `#[thread_local]` static, in which case the asm code can combine the symbol with relocations (e.g. `@plt`, `@TPOFF`) to read from thread-local data.\n\nOperand expressions are evaluated from left to right, just like function call arguments. After the `asm!` has executed, outputs are written to in left to right order. This is significant if two outputs point to the same place: that place will contain the value of the rightmost output.\n\n## Register operands\n\nInput and output operands can be specified either as an explicit register or as a register class from which the register allocator can select a register. Explicit registers are specified as string literals (e.g. `\"eax\"`) while register classes are specified as identifiers (e.g. `reg`). Using string literals for register names enables support for architectures that use special characters in register names, such as MIPS (`$0`, `$1`, etc).\n\nNote that explicit registers treat register aliases (e.g. `r14` vs `lr` on ARM) and smaller views of a register (e.g. `eax` vs `rax`) as equivalent to the base register. It is a compile-time error to use the same explicit register for two input operands or two output operands. Additionally, it is also a compile-time error to use overlapping registers (e.g. ARM VFP) in input operands or in output operands.\n\nOnly the following types are allowed as operands for inline assembly:\n- Integers (signed and unsigned)\n- Floating-point numbers\n- Pointers (thin only)\n- Function pointers\n- SIMD vectors (structs defined with `#[repr(simd)]` and which implement `Copy`). This includes architecture-specific vector types defined in `std::arch` such as `__m128` (x86) or `int8x16_t` (ARM).\n\nHere is the list of currently supported register classes:\n\n| Architecture | Register class | Registers | LLVM constraint code |\n| ------------ | -------------- | --------- | -------------------- |\n| x86 | `reg` | `ax`, `bx`, `cx`, `dx`, `si`, `di`, `r[8-15]` (x86-64 only) | `r` |\n| x86 | `reg_abcd` | `ax`, `bx`, `cx`, `dx` | `Q` |\n| x86-32 | `reg_byte` | `al`, `bl`, `cl`, `dl`, `ah`, `bh`, `ch`, `dh` | `q` |\n| x86-64 | `reg_byte` | `al`, `bl`, `cl`, `dl`, `sil`, `dil`, `r[8-15]b`, `ah`\\*, `bh`\\*, `ch`\\*, `dh`\\* | `q` |\n| x86 | `xmm_reg` | `xmm[0-7]` (x86) `xmm[0-15]` (x86-64) | `x` |\n| x86 | `ymm_reg` | `ymm[0-7]` (x86) `ymm[0-15]` (x86-64) | `x` |\n| x86 | `zmm_reg` | `zmm[0-7]` (x86) `zmm[0-31]` (x86-64) | `v` |\n| x86 | `kreg` | `k[1-7]` | `Yk` |\n| AArch64 | `reg` | `x[0-28]`, `x30` | `r` |\n| AArch64 | `vreg` | `v[0-31]` | `w` |\n| AArch64 | `vreg_low16` | `v[0-15]` | `x` |\n| ARM | `reg` | `r[0-5]` `r7`\\*, `r[8-10]`, `r11`\\*, `r12`, `r14` | `r` |\n| ARM (Thumb) | `reg_thumb` | `r[0-r7]` | `l` |\n| ARM (ARM) | `reg_thumb` | `r[0-r10]`, `r12`, `r14` | `l` |\n| ARM | `sreg` | `s[0-31]` | `t` |\n| ARM | `sreg_low16` | `s[0-15]` | `x` |\n| ARM | `dreg` | `d[0-31]` | `w` |\n| ARM | `dreg_low16` | `d[0-15]` | `t` |\n| ARM | `dreg_low8` | `d[0-8]` | `x` |\n| ARM | `qreg` | `q[0-15]` | `w` |\n| ARM | `qreg_low8` | `q[0-7]` | `t` |\n| ARM | `qreg_low4` | `q[0-3]` | `x` |\n| NVPTX | `reg16` | None\\* | `h` |\n| NVPTX | `reg32` | None\\* | `r` |\n| NVPTX | `reg64` | None\\* | `l` |\n| RISC-V | `reg` | `x1`, `x[5-7]`, `x[9-15]`, `x[16-31]` (non-RV32E) | `r` |\n| RISC-V | `freg` | `f[0-31]` | `f` |\n| Hexagon | `reg` | `r[0-28]` | `r` |\n\n> **Note**: On x86 we treat `reg_byte` differently from `reg` because the compiler can allocate `al` and `ah` separately whereas `reg` reserves the whole register.\n>\n> Note #2: On x86-64 the high byte registers (e.g. `ah`) are only available when used as an explicit register. Specifying the `reg_byte` register class for an operand will always allocate a low byte register.\n>\n> Note #3: NVPTX doesn't have a fixed register set, so named registers are not supported.\n>\n> Note #4: On ARM the frame pointer is either `r7` or `r11` depending on the platform.\n\nAdditional register classes may be added in the future based on demand (e.g. MMX, x87, etc).\n\nEach register class has constraints on which value types they can be used with. This is necessary because the way a value is loaded into a register depends on its type. For example, on big-endian systems, loading a `i32x4` and a `i8x16` into a SIMD register may result in different register contents even if the byte-wise memory representation of both values is identical. The availability of supported types for a particular register class may depend on what target features are currently enabled.\n\n| Architecture | Register class | Target feature | Allowed types |\n| ------------ | -------------- | -------------- | ------------- |\n| x86-32 | `reg` | None | `i16`, `i32`, `f32` |\n| x86-64 | `reg` | None | `i16`, `i32`, `f32`, `i64`, `f64` |\n| x86 | `reg_byte` | None | `i8` |\n| x86 | `xmm_reg` | `sse` | `i32`, `f32`, `i64`, `f64`,

The only exception is the `freg` register class on RISC-V where `f32` values are NaN-boxed in a `f64` as required by the RISC-V architecture.\n\nWhen separate input and output expressions are specified for an `inout` operand, both expressions must have the same type. The only exception is if both operands are pointers or integers, in which case they are only required to have the same size. This restriction exists because the register allocators in LLVM and GCC sometimes cannot handle tied operands with different types.\n\n## Register names\n\nSome registers have multiple names.

The frame pointer cannot be used as an input or output. |\n| ARM | `r6` | `r6` is used internally by LLVM as a base pointer and therefore cannot be used as an input or output. |\n| x86 | `k0` | This is a constant zero register which can't be modified. |\n| x86 | `ip` | This is the program counter, not a real register. |\n| x86 | `mm[0-7]` | MMX registers are not currently supported (but may be in the future). |\n| x86 | `st([0-7])` | x87 registers are not currently supported (but may be in the future). |\n| AArch64 | `xzr` | This is a constant zero register which can't be modified. |\n| ARM | `pc` | This is the program counter, not a real register. |\n| RISC-V | `x0` | This is a constant zero register which can't be modified. |\n| RISC-V | `gp`, `tp` | These registers are reserved and cannot be used as inputs or outputs. |\n| Hexagon | `lr` | This is the link register which cannot be used as an input or output. |\n\n## Template modifiers\n\nThe placeholders can be augmented by modifiers which are specified after the `:` in the curly braces. These modifiers do not affect register allocation, but change the way operands are formatted when inserted into the template string. Only one modifier is allowed per template placeholder.\n\nThe supported modifiers are a subset of LLVM's (and GCC's) [asm template argument modifiers][llvm-argmod], but do not use the same letter codes.\n\n| Architecture | Register class | Modifier | Example output | LLVM modifier |\n| ------------ | -------------- | -------- | -------------- | ------------- |\n| x86-32 | `reg` | None | `eax` | `k` |\n| x86-64 | `reg` | None | `rax` | `q` |\n| x86-32 | `reg_abcd` | `l` | `al` | `b` |\n| x86-64 | `reg` | `l` | `al` | `b` |\n| x86 | `reg_abcd` | `h` | `ah` | `h` |\n| x86 | `reg` | `x` | `ax` | `w` |\n| x86 | `reg` | `e` | `eax` | `k` |\n| x86-64 | `reg` | `r` | `rax` | `q` |\n| x86 | `reg_byte` | None | `al` / `ah` | None |\n| x86 | `xmm_reg` | None | `xmm0` | `x` |\n| x86 | `ymm_reg` | None | `ymm0` | `t` |\n| x86 | `zmm_reg` | None | `zmm0` | `g` |\n| x86 | `*mm_reg` | `x` | `xmm0` | `x` |\n| x86 | `*mm_reg` | `y` | `ymm0` | `t` |\n| x86 | `*mm_reg` | `z` | `zmm0` | `g` |\n| x86 | `kreg` | None | `k1` | None |\n| AArch64 | `reg` | None | `x0` | `x` |\n| AArch64 | `reg` | `w` | `w0` | `w` |\n| AArch64 | `reg` | `x` | `x0` | `x` |\n| AArch64 | `vreg` | None | `v0` | None |\n| AArch64 | `vreg` | `v` | `v0` | None |\n| AArch64 | `vreg` | `b` | `b0` | `b` |\n| AArch64 | `vreg` | `h` | `h0` | `h` |\n| AArch64 | `vreg` | `s` | `s0` | `s` |\n| AArch64 | `vreg` | `d` | `d0` | `d` |\n| AArch64 | `vreg` | `q` | `q0` | `q` |\n| ARM | `reg` | None | `r0` | None |\n| ARM | `sreg` | None | `s0` | None |\n| ARM | `dreg` | None | `d0` | `P` |\n| ARM | `qreg` | None | `q0` | `q` |\n| ARM | `qreg` | `e` / `f` | `d0` / `d1` | `e` / `f` |\n| NVPTX | `reg16` | None | `rs0` | None |\n| NVPTX | `reg32` | None | `r0` | None |\n| NVPTX | `reg64` | None | `rd0` | None |\n| RISC-V | `reg` | None | `x1` | None |\n| RISC-V | `freg` | None | `f0` | None |\n| Hexagon | `reg` | None | `r0` | None |\n\n> Notes:\n> - on ARM `e` / `f`: this prints the low or high doubleword register name of a NEON quad (128-bit) register.\n> - on x86: our behavior for `reg` with no modifiers differs from what GCC does. GCC will infer the modifier based on the operand value type, while we default to the full register size.\n> - on x86 `xmm_reg`: the `x`, `t` and `g` LLVM modifiers are not yet implemented in LLVM (they are supported by GCC only), but this should be a simple change.\n\nAs stated in the previous section, passing an input value smaller than the register width will result in the upper bits of the register containing undefined values. This is not a problem if the inline asm only accesses the lower bits of the register, which can be done by using a template modifier to use a subregister name in the asm code (e.g. `ax` instead of `rax`). Since this an easy pitfall, the compiler will suggest a template modifier to use where appropriate given the input type. If all references to an operand already have modifiers then the warning is suppressed for that operand.\n\n[llvm-argmod]: http://llvm.org/docs/LangRef.html#asm-template-argument-modifiers\n\n## Options\n\nFlags are used to further influence the behavior of the inline assembly block.\nCurrently the following options are defined:\n- `pure`: The `asm` block has no side effects, and its outputs depend only on its direct inputs (i.e. the values themselves, not what they point to) or values read from memory (unless the `nomem` options is also set). This allows the compiler to execute the `asm` block fewer times than specified in the program (e.g. by hoisting it out of a loop) or even eliminate it entirely if the outputs are not used.\n- `nomem`: The `asm` blocks does not read or write to any memory. This allows the compiler to cache the values of modified global variables in registers across the `asm` block since it knows that they are not read or written to by the `asm`.\n- `readonly`: The `asm` block does not write to any memory. This allows the compiler to cache the values of unmodified global variables in registers across the `asm` block since it knows that they are not written to by the `asm`.\n- `preserves_flags`: The `asm` block does not modify the flags register (defined in the rules below). This allows the compiler to avoid recomputing the condition flags after the `asm` block.\n- `noreturn`: The `asm` block never returns, and its return type is defined as `!` (never). Behavior is undefined if execution falls through past the end of the asm code. A `noreturn` asm block behaves just like a function which doesn't return; notably, local variables in scope are not dropped before it is invoked.\n- `nostack`: The `asm` block does not push data to the stack, or write to the stack red-zone (if supported by the target). If this option is *not* used then the stack pointer is guaranteed to be suitably aligned (according to the target ABI) for a function call.\n- `att_syntax`: This option is only valid on x86, and causes the assembler to use the `.att_syntax prefix` mode of the GNU assembler. Register operands are substituted in with a leading `%`.\n\nThe compiler performs some additional checks on options:\n- The `nomem` and `readonly` options are mutually exclusive: it is a compile-time error to specify both.\n- The `pure` option must be combined with either the `nomem` or `readonly` options, otherwise a compile-time error is emitted.\n- It is a compile-time error to specify `pure` on an asm block with no outputs or only discarded outputs (`_`).\n- It is a compile-time error to specify `noreturn` on an asm block with outputs.\n\n## Rules for inline assembly\n\n- Any registers not specified as inputs will contain an undefined value on entry to the asm block.\n - An \"undefined value\" in the context of inline assembly means that the register can (non-deterministically) have any one of the possible values allowed by the architecture. Notably it is not the same as an LLVM `undef` which can have a different value every time you read it (since such a concept does not exist in assembly code).\n- Any registers not specified as outputs must have the same value upon exiting the asm block as they had on entry, otherwise behavior is undefined.\n - This only applies to registers which can be specified as an input or output. Other registers follow target-specific rules.\n - Note that a `lateout` may be allocated to the same register as an `in`, in which case this rule does not apply. Code should not rely on this however since it depends on the results of register allocation.\n- Behavior is undefined if execution unwinds out of an asm block.\n - This also applies if the assembly code calls a function which then unwinds.\n- The set of memory locations that assembly code is allowed the read and write are the same as those allowed for an FFI function.\n - Refer to the unsafe code guidelines for the exact rules.\n - If the `readonly` option is set, then only memory reads are allowed.\n - If the `nomem` option is set then no reads or writes to memory are allowed.\n - These rules do not apply to memory which is private to the asm code, such as stack space allocated within the asm block.\n- The compiler cannot assume that the instructions in the asm are the ones that will actually end up executed.\n - This effectively means that the compiler must treat the `asm!` as a black box and only take the interface specification into account, not the instructions themselves.\n - Runtime code patching is allowed, via target-specific mechanisms (outside the scope of this RFC).\n- Unless the `nostack` option is set, asm code is allowed to use stack space below the stack pointer.\n - On entry to the asm block the stack pointer is guaranteed to be suitably aligned (according to the target ABI) for a function call.\n - You are responsible for making sure you don't overflow the stack (e.g. use stack probing to ensure you hit a guard page).\n - You should adjust the stack pointer when allocating stack memory as required by the target ABI.\n - The stack pointer must be restored to its original value before leaving the asm block.\n- If the `noreturn` option is set then behavior is undefined if execution falls through to the end of the asm block.\n- If the `pure` option is set then behavior is undefined if the `asm` has side-effects other than its direct outputs. Behavior is also undefined if two executions of the `asm` code with the same inputs result in different outputs.\n - When used with the `nomem` option, \"inputs\" are just the direct inputs of the `asm!`.\n - When used with the `readonly` option, \"inputs\" comprise the direct inputs of the `asm!` and any memory that the `asm!` block is allowed to read.\n- These flags registers must be restored upon exiting the asm block if the `preserves_flags` option is set:\n - x86\n - Status flags in `EFLAGS` (CF, PF, AF, ZF, SF, OF).\n - Floating-point status word (all).\n - Floating-point exception flags in `MXCSR` (PE, UE, OE, ZE, DE, IE).\n - ARM\n - Condition flags in `CPSR` (N, Z, C, V)\n - Saturation flag in `CPSR` (Q)\n - Greater than or equal flags in `CPSR` (GE).\n - Condition flags in `FPSCR` (N, Z, C, V)\n - Saturation flag in `FPSCR` (QC)\n - Floating-point exception flags in `FPSCR` (IDC, IXC, UFC, OFC, DZC, IOC).\n - AArch64\n - Condition flags (`NZCV` register).\n - Floating-point status (`FPSR` register).\n - RISC-V\n - Floating-point exception flags in `fcsr` (`fflags`).\n- On x86, the direction flag (DF in `EFLAGS`) is clear on entry to an asm block and must be clear on exit.\n - Behavior is undefined if the direction flag is set on exiting an asm block.\n- The requirement of restoring the stack pointer and non-output registers to their original value only applies when exiting an `asm!` block.\n - This means that `asm!` blocks that never return (even if not marked `noreturn`) don't need to preserve these registers.\n - When returning to a different `asm!` block than you entered (e.g. for context switching), these registers must contain the value they had upon entering the `asm!` block that you are *exiting*.\n - You cannot exit an `asm!` block that has not been entered. Neither can you exit an `asm!` block that has already been exited.\n - You are responsible for switching any target-specific state (e.g. thread-local storage, stack bounds).\n - The set of memory locations that you may access is the intersection of those allowed by the `asm!` blocks you entered and exited.\n- You cannot assume that an `asm!` block will appear exactly once in the output binary. The compiler is allowed to instantiate multiple copies of the `asm!` block, for example when the function containing it is inlined in multiple places.\n - As a consequence, you should only use [local labels] inside inline assembly code. Defining symbols in assembly code may lead to assembler and/or linker errors due to duplicate symbol definitions.\n\n> **Note**: As a general rule, the flags covered by `preserves_flags` are those which are *not* preserved when performing a function call.\n\n[local labels]: https://sourceware.org/binutils/docs/as/Symbol-Names.html#Local-Labels\n" } , LintCompletion { label : "is_sorted" ,

This is useful for very low level programming, where\nwhich register you use is important:\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# unsafe fn read_byte_in(port: u16) -> u8 {\nlet result: u8;\nllvm_asm!(\"in %dx, %al\" : \"={al}\"(result) : \"{dx}\"(port));\nresult\n# }\n```\n\n## Clobbers\n\nSome instructions modify registers which might otherwise have held\ndifferent values so we use the clobbers list to indicate to the\ncompiler not to assume any values loaded into those registers will\nstay valid.\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# fn main() { unsafe {\n// Put the value 0x200 in eax:\nllvm_asm!(\"mov $$0x200, %eax\" : /* no outputs */ : /* no inputs */ : \"eax\");\n# } }\n# #[cfg(not(any(target_arch = \"x86\", target_arch = \"x86_64\")))]\n# fn main() {}\n```\n\nInput and output registers need not be listed since that information\nis already communicated by the given constraints. Otherwise, any other\nregisters used either implicitly or explicitly should be listed.\n\nIf the assembly changes the condition code register `cc` should be\nspecified as one of the clobbers. Similarly, if the assembly modifies\nmemory, `memory` should also be specified.\n\n## Options\n\nThe last section, `options` is specific to Rust. The format is comma\nseparated literal strings (i.e. `:\"foo\", \"bar\", \"baz\"`). It's used to\nspecify some extra info about the inline assembly:\n\nCurrent valid options are:\n\n1. *volatile* - specifying this is analogous to\n `__asm__ __volatile__ (...)` in gcc/clang.\n2. *alignstack* - certain instructions expect the stack to be\n aligned a certain way (i.e. SSE) and specifying this indicates to\n the compiler to insert its usual stack alignment code\n3. *intel* - use intel syntax instead of the default AT&T.\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# fn main() {\nlet result: i32;\nunsafe {\n llvm_asm!(\"mov eax, 2\" : \"={eax}\"(result) : : : \"intel\")\n}\nprintln!(\"eax is currently {}\", result);\n# }\n# #[cfg(not(any(target_arch = \"x86\", target_arch = \"x86_64\")))]\n# fn main() {}\n```\n\n## More Information\n\nThe current implementation of the `llvm_asm!` macro is a direct binding to [LLVM's\ninline assembler expressions][llvm-docs], so be sure to check out [their\ndocumentation as well][llvm-docs] for more information about clobbers,\nconstraints, etc.\n\n[llvm-docs]: http://llvm.org/docs/LangRef.html#inline-assembler-expressions\n\nIf you need more power and don't mind losing some of the niceties of\n`llvm_asm!`, check out [global_asm](global-asm.md).\n" } ] ; From 06ff8e6c760ff05f10e868b5d1f9d79e42fbb49c Mon Sep 17 00:00:00 2001 From: Dmitry Date: Sat, 15 Aug 2020 01:25:08 +0700 Subject: [PATCH 17/20] refactor requirements put forward mkladov --- .../completion/unstable_feature_descriptor.rs | 2 +- xtask/src/codegen.rs | 1 + .../codegen/gen_unstable_future_descriptor.rs | 40 +++++++++---------- 3 files changed, 22 insertions(+), 21 deletions(-) diff --git a/crates/ra_ide/src/completion/unstable_feature_descriptor.rs b/crates/ra_ide/src/completion/unstable_feature_descriptor.rs index 13297741a6..14cd583eaa 100644 --- a/crates/ra_ide/src/completion/unstable_feature_descriptor.rs +++ b/crates/ra_ide/src/completion/unstable_feature_descriptor.rs @@ -1,4 +1,4 @@ //!

A generator is a \"resumable function\" that syntactically\nresembles a closure but compiles to much different semantics in the compiler\nitself. The primary feature of a generator is that it can be suspended during\nexecution to be resumed at a later date. Generators use the `yield` keyword to\n\"return\", and then the caller can `resume` a generator to resume execution just\nafter the `yield` keyword.\n\nGenerators are an extra-unstable feature in the compiler right now. Added in\n[RFC 2033] they're mostly intended right now as a information/constraint\ngathering phase. The intent is that experimentation can happen on the nightly\ncompiler before actual stabilization. A further RFC will be required to\nstabilize generators/coroutines and will likely contain at least a few small\ntweaks to the overall design.\n\n[RFC 2033]: https://github.com/rust-lang/rfcs/pull/2033\n\nA syntactical example of a generator is:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::{Generator, GeneratorState};\nuse std::pin::Pin;\n\nfn main() {\n let mut generator = || {\n yield 1;\n return \"foo\"\n };\n\n match Pin::new(&mut generator).resume(()) {\n GeneratorState::Yielded(1) => {}\n _ => panic!(\"unexpected value from resume\"),\n }\n match Pin::new(&mut generator).resume(()) {\n GeneratorState::Complete(\"foo\") => {}\n _ => panic!(\"unexpected value from resume\"),\n }\n}\n```\n\nGenerators are closure-like literals which can contain a `yield` statement. The\n`yield` statement takes an optional expression of a value to yield out of the\ngenerator. All generator literals implement the `Generator` trait in the\n`std::ops` module. The `Generator` trait has one main method, `resume`, which\nresumes execution of the generator at the previous suspension point.\n\nAn example of the control flow of generators is that the following example\nprints all numbers in order:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::Generator;\nuse std::pin::Pin;\n\nfn main() {\n let mut generator = || {\n println!(\"2\");\n yield;\n println!(\"4\");\n };\n\n println!(\"1\");\n Pin::new(&mut generator).resume(());\n println!(\"3\");\n Pin::new(&mut generator).resume(());\n println!(\"5\");\n}\n```\n\nAt this time the main intended use case of generators is an implementation\nprimitive for async/await syntax, but generators will likely be extended to\nergonomic implementations of iterators and other primitives in the future.\nFeedback on the design and usage is always appreciated!\n\n### The `Generator` trait\n\nThe `Generator` trait in `std::ops` currently looks like:\n\n```rust\n# #![feature(arbitrary_self_types, generator_trait)]\n# use std::ops::GeneratorState;\n# use std::pin::Pin;\n\npub trait Generator {\n type Yield;\n type Return;\n fn resume(self: Pin<&mut Self>, resume: R) -> GeneratorState;\n}\n```\n\nThe `Generator::Yield` type is the type of values that can be yielded with the\n`yield` statement. The `Generator::Return` type is the returned type of the\ngenerator. This is typically the last expression in a generator's definition or\nany value passed to `return` in a generator. The `resume` function is the entry\npoint for executing the `Generator` itself.\n\nThe return value of `resume`, `GeneratorState`, looks like:\n\n```rust\npub enum GeneratorState {\n Yielded(Y),\n Complete(R),\n}\n```\n\nThe `Yielded` variant indicates that the generator can later be resumed. This\ncorresponds to a `yield` point in a generator. The `Complete` variant indicates\nthat the generator is complete and cannot be resumed again. Calling `resume`\nafter a generator has returned `Complete` will likely result in a panic of the\nprogram.\n\n### Closure-like semantics\n\nThe closure-like syntax for generators alludes to the fact that they also have\nclosure-like semantics. Namely:\n\n* When created, a generator executes no code. A closure literal does not\n actually execute any of the closure's code on construction, and similarly a\n generator literal does not execute any code inside the generator when\n constructed.\n\n* Generators can capture outer variables by reference or by move, and this can\n be tweaked with the `move` keyword at the beginning of the closure. Like\n closures all generators will have an implicit environment which is inferred by\n the compiler. Outer variables can be moved into a generator for use as the\n generator progresses.\n\n* Generator literals produce a value with a unique type which implements the\n `std::ops::Generator` trait. This allows actual execution of the generator\n through the `Generator::resume` method as well as also naming it in return\n types and such.\n\n* Traits like `Send` and `Sync` are automatically implemented for a `Generator`\n depending on the captured variables of the environment. Unlike closures,\n generators also depend on variables live across suspension points. This means\n that although the ambient environment may be `Send` or `Sync`, the generator\n itself may not be due to internal variables live across `yield` points being\n not-`Send` or not-`Sync`. Note that generators do\n not implement traits like `Copy` or `Clone` automatically.\n\n* Whenever a generator is dropped it will drop all captured environment\n variables.\n\n### Generators as state machines\n\nIn the compiler, generators are currently compiled as state machines. Each\n`yield` expression will correspond to a different state that stores all live\nvariables over that suspension point. Resumption of a generator will dispatch on\nthe current state and then execute internally until a `yield` is reached, at\nwhich point all state is saved off in the generator and a value is returned.\n\nLet's take a look at an example to see what's going on here:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::Generator;\nuse std::pin::Pin;\n\nfn main() {\n let ret = \"foo\";\n let mut generator = move || {\n yield 1;\n return ret\n };\n\n Pin::new(&mut generator).resume(());\n Pin::new(&mut generator).resume(());\n}\n```\n\nThis generator literal will compile down to something similar to:\n\n```rust\n#![feature(arbitrary_self_types, generators, generator_trait)]\n\nuse std::ops::{Generator, GeneratorState};\nuse std::pin::Pin;\n\nfn main() {\n let ret = \"foo\";\n let mut generator = {\n enum __Generator {\n Start(&'static str),\n Yield1(&'static str),\n Done,\n }\n\n impl Generator for __Generator {\n type Yield = i32;\n type Return = &'static str;\n\n fn resume(mut self: Pin<&mut Self>, resume: ()) -> GeneratorState {\n use std::mem;\n match mem::replace(&mut *self, __Generator::Done) {\n __Generator::Start(s) => {\n *self = __Generator::Yield1(s);\n GeneratorState::Yielded(1)\n }\n\n __Generator::Yield1(s) => {\n *self = __Generator::Done;\n GeneratorState::Complete(s)\n }\n\n __Generator::Done => {\n panic!(\"generator resumed after completion\")\n }\n }\n }\n }\n\n __Generator::Start(ret)\n };\n\n Pin::new(&mut generator).resume(());\n Pin::new(&mut generator).resume(());\n}\n```\n\nNotably here we can see that the compiler is generating a fresh type,\n`__Generator` in this case. This type has a number of states (represented here\nas an `enum`) corresponding to each of the conceptual states of the generator.\nAt the beginning we're closing over our outer variable `foo` and then that\nvariable is also live over the `yield` point, so it's stored in both states.\n\nWhen the generator starts it'll immediately yield 1, but it saves off its state\njust before it does so indicating that it has reached the yield point.

The syntax isn't final, either. We may need an alternative syntax for Rust 2015 because, in Rust 2015, expressions like `[e; dyn(1)]` would be ambiguous. One possible alternative proposed in the RFC is `[e; n]`: if `n` captures one or more local variables, then it is considered as `[e; dyn n]`.\n\n## Advisory on stack usage\n\nIt's advised not to casually use the `#![feature(unsized_locals)]` feature. Typical use-cases are:\n\n- When you need a by-value trait objects.\n- When you really need a fast allocation of small temporary arrays.\n\nAnother pitfall is repetitive allocation and temporaries. Currently the compiler simply extends the stack frame every time it encounters an unsized assignment. So for example, the code\n\n```rust\n#![feature(unsized_locals)]\n\nfn main() {\n let x: Box<[i32]> = Box::new([1, 2, 3, 4, 5]);\n let _x = {{{{{{{{{{*x}}}}}}}}}};\n}\n```\n\nand the code\n\n```rust\n#![feature(unsized_locals)]\n\nfn main() {\n for _ in 0..10 {\n let x: Box<[i32]> = Box::new([1, 2, 3, 4, 5]);\n let _x = *x;\n }\n}\n```\n\nwill unnecessarily extend the stack frame.\n" } , LintCompletion { label : "or_patterns" , description : "# `or_patterns`\n\nThe tracking issue for this feature is: [#54883]\n\n[#54883]: https://github.com/rust-lang/rust/issues/54883\n\n------------------------\n\nThe `or_pattern` language feature allows `|` to be arbitrarily nested within\na pattern, for example, `Some(A(0) | B(1 | 2))` becomes a valid pattern.\n\n## Examples\n\n```rust,ignore\n#![feature(or_patterns)]\n\npub enum Foo {\n Bar,\n Baz,\n Quux,\n}\n\npub fn example(maybe_foo: Option) {\n match maybe_foo {\n Some(Foo::Bar | Foo::Baz) => {\n println!(\"The value contained `Bar` or `Baz`\");\n }\n Some(_) => {\n println!(\"The value did not contain `Bar` or `Baz`\");\n }\n None => {\n println!(\"The value was `None`\");\n }\n }\n}\n```\n" } , LintCompletion { label : "member_constraints" , description : "# `member_constraints`\n\nThe tracking issue for this feature is: [#61997]\n\n[#61997]: https://github.com/rust-lang/rust/issues/61997\n\n------------------------\n\nThe `member_constraints` feature gate lets you use `impl Trait` syntax with\nmultiple unrelated lifetime parameters.\n\nA simple example is:\n\n```rust\n#![feature(member_constraints)]\n\ntrait Trait<'a, 'b> { }\nimpl Trait<'_, '_> for T {}\n\nfn foo<'a, 'b>(x: &'a u32, y: &'b u32) -> impl Trait<'a, 'b> {\n (x, y)\n}\n\nfn main() { }\n```\n\nWithout the `member_constraints` feature gate, the above example is an\nerror because both `'a` and `'b` appear in the impl Trait bounds, but\nneither outlives the other.\n" } , LintCompletion { label : "optin_builtin_traits" , description : "# `optin_builtin_traits`\n\nThe tracking issue for this feature is [#13231] \n\n[#13231]: https://github.com/rust-lang/rust/issues/13231\n\n----\n\nThe `optin_builtin_traits` feature gate allows you to define auto traits.\n\nAuto traits, like [`Send`] or [`Sync`] in the standard library, are marker traits\nthat are automatically implemented for every type, unless the type, or a type it contains, \nhas explicitly opted out via a negative impl.

These automatic impls contain a where clause for each field\nof the form `T: AutoTrait`, where `T` is the type of the field and\n`AutoTrait` is the auto trait in question. As an example, consider the\nstruct `List` and the auto trait `Send`:\n\n```rust\nstruct List {\n data: T,\n next: Option>>,\n}\n```\n\nPresuming that there is no explicit impl of `Send` for `List`, the\ncompiler will supply an automatic impl of the form:\n\n```rust\nstruct List {\n data: T,\n next: Option>>,\n}\n\nunsafe impl Send for List\nwhere\n T: Send, // from the field `data`\n Option>>: Send, // from the field `next`\n{ }\n```\n\nExplicit impls may be either positive or negative. They take the form:\n\n```rust,ignore\nimpl<...> AutoTrait for StructName<..> { }\nimpl<...> !AutoTrait for StructName<..> { }\n```\n\n## Coinduction: Auto traits permit cyclic matching\n\nUnlike ordinary trait matching, auto traits are **coinductive**. This\nmeans, in short, that cycles which occur in trait matching are\nconsidered ok. As an example, consider the recursive struct `List`\nintroduced in the previous section. In attempting to determine whether\n`List: Send`, we would wind up in a cycle: to apply the impl, we must\nshow that `Option>: Send`, which will in turn require\n`Box: Send` and then finally `List: Send` again. Under ordinary\ntrait matching, this cycle would be an error, but for an auto trait it\nis considered a successful match.\n\n## Items\n\nAuto traits cannot have any trait items, such as methods or associated types. This ensures that we can generate default implementations.\n\n## Supertraits\n\nAuto traits cannot have supertraits.

The marker is the attribute `#[lang = \"...\"]` and there are\nvarious different values of `...`, i.e. various different 'lang\nitems'.\n\nFor example, `Box` pointers require two lang items, one for allocation\nand one for deallocation. A freestanding program that uses the `Box`\nsugar for dynamic allocations via `malloc` and `free`:\n\n```rust,ignore\n#![feature(lang_items, box_syntax, start, libc, core_intrinsics)]\n#![no_std]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\nextern crate libc;\n\n#[lang = \"owned_box\"]\npub struct Box(*mut T);\n\n#[lang = \"exchange_malloc\"]\nunsafe fn allocate(size: usize, _align: usize) -> *mut u8 {\n let p = libc::malloc(size as libc::size_t) as *mut u8;\n\n // Check if `malloc` failed:\n if p as usize == 0 {\n intrinsics::abort();\n }\n\n p\n}\n\n#[lang = \"box_free\"]\nunsafe fn box_free(ptr: *mut T) {\n libc::free(ptr as *mut libc::c_void)\n}\n\n#[start]\nfn main(_argc: isize, _argv: *const *const u8) -> isize {\n let _x = box 1;\n\n 0\n}\n\n#[lang = \"eh_personality\"] extern fn rust_eh_personality() {}\n#[lang = \"panic_impl\"] extern fn rust_begin_panic(info: &PanicInfo) -> ! { unsafe { intrinsics::abort() } }\n#[no_mangle] pub extern fn rust_eh_register_frames () {}\n#[no_mangle] pub extern fn rust_eh_unregister_frames () {}\n```\n\nNote the use of `abort`: the `exchange_malloc` lang item is assumed to\nreturn a valid pointer, and so needs to do the check internally.\n\nOther features provided by lang items include:\n\n- overloadable operators via traits: the traits corresponding to the\n `==`, `<`, dereferencing (`*`) and `+` (etc.) operators are all\n marked with lang items; those specific four are `eq`, `ord`,\n `deref`, and `add` respectively.\n- stack unwinding and general failure; the `eh_personality`,\n `panic` and `panic_bounds_checks` lang items.\n- the traits in `std::marker` used to indicate types of\n various kinds; lang items `send`, `sync` and `copy`.\n- the marker types and variance indicators found in\n `std::marker`; lang items `covariant_type`,\n `contravariant_lifetime`, etc.\n\nLang items are loaded lazily by the compiler; e.g. if one never uses\n`Box` then there is no need to define functions for `exchange_malloc`\nand `box_free`. `rustc` will emit an error when an item is needed\nbut not found in the current crate or any that it depends on.\n\nMost lang items are defined by `libcore`, but if you're trying to build\nan executable without the standard library, you'll run into the need\nfor lang items. The rest of this page focuses on this use-case, even though\nlang items are a bit broader than that.\n\n### Using libc\n\nIn order to build a `#[no_std]` executable we will need libc as a dependency.\nWe can specify this using our `Cargo.toml` file:\n\n```toml\n[dependencies]\nlibc = { version = \"0.2.14\", default-features = false }\n```\n\nNote that the default features have been disabled. This is a critical step -\n**the default features of libc include the standard library and so must be\ndisabled.**\n\n### Writing an executable without stdlib\n\nControlling the entry point is possible in two ways: the `#[start]` attribute,\nor overriding the default shim for the C `main` function with your own.\n\nThe function marked `#[start]` is passed the command line parameters\nin the same format as C:\n\n```rust,ignore\n#![feature(lang_items, core_intrinsics)]\n#![feature(start)]\n#![no_std]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\n// Pull in the system libc library for what crt0.o likely requires.\nextern crate libc;\n\n// Entry point for this program.\n#[start]\nfn start(_argc: isize, _argv: *const *const u8) -> isize {\n 0\n}\n\n// These functions are used by the compiler, but not\n// for a bare-bones hello world. These are normally\n// provided by libstd.\n#[lang = \"eh_personality\"]\n#[no_mangle]\npub extern fn rust_eh_personality() {\n}\n\n#[lang = \"panic_impl\"]\n#[no_mangle]\npub extern fn rust_begin_panic(info: &PanicInfo) -> ! {\n unsafe { intrinsics::abort() }\n}\n```\n\nTo override the compiler-inserted `main` shim, one has to disable it\nwith `#![no_main]` and then create the appropriate symbol with the\ncorrect ABI and the correct name, which requires overriding the\ncompiler's name mangling too:\n\n```rust,ignore\n#![feature(lang_items, core_intrinsics)]\n#![feature(start)]\n#![no_std]\n#![no_main]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\n// Pull in the system libc library for what crt0.o likely requires.\nextern crate libc;\n\n// Entry point for this program.\n#[no_mangle] // ensure that this symbol is called `main` in the output\npub extern fn main(_argc: i32, _argv: *const *const u8) -> i32 {\n 0\n}\n\n// These functions are used by the compiler, but not\n// for a bare-bones hello world.

You may observe this via linker error messages\nsuch as \"```undefined reference to `__rust_probestack'```\".\n\n## More about the language items\n\nThe compiler currently makes a few assumptions about symbols which are\navailable in the executable to call. Normally these functions are provided by\nthe standard library, but without it you must define your own. These symbols\nare called \"language items\", and they each have an internal name, and then a\nsignature that an implementation must conform to.\n\nThe first of these functions, `rust_eh_personality`, is used by the failure\nmechanisms of the compiler. This is often mapped to GCC's personality function\n(see the [libstd implementation][unwind] for more information), but crates\nwhich do not trigger a panic can be assured that this function is never\ncalled.

Negative impls are a commitment not to implement the given trait for the named types.\n\n## Orphan and overlap rules\n\nNegative impls must obey the same orphan rules as a positive impl. This implies you cannot add a negative impl for types defined in upstream crates and so forth.\n\nSimilarly, negative impls cannot overlap with positive impls, again using the same \"overlap\" check that we ordinarily use to determine if two impls overlap. (Note that positive impls typically cannot overlap with one another either, except as permitted by specialization.)\n\n## Interaction with auto traits\n\nDeclaring a negative impl `impl !SomeAutoTrait for SomeType` for an\nauto-trait serves two purposes:\n\n* as with any trait, it declares that `SomeType` will never implement `SomeAutoTrait`;\n* it disables the automatic `SomeType: SomeAutoTrait` impl that would otherwise have been generated.\n\nNote that, at present, there is no way to indicate that a given type\ndoes not implement an auto trait *but that it may do so in the\nfuture*. For ordinary types, this is done by simply not declaring any\nimpl at all, but that is not an option for auto traits. A workaround\nis that one could embed a marker type as one of the fields, where the\nmarker type is `!AutoTrait`.\n\n## Immediate uses\n\nNegative impls are used to declare that `&T: !DerefMut` and `&mut T: !Clone`, as required to fix the soundness of `Pin` described in [#66544](https://github.com/rust-lang/rust/issues/66544).\n\nThis serves two purposes:\n\n* For proving the correctness of unsafe code, we can use that impl as evidence that no `DerefMut` or `Clone` impl exists.\n* It prevents downstream crates from creating such impls.\n" } , LintCompletion { label : "abi_ptx" , description : "# `abi_ptx`\n\nThe tracking issue for this feature is: [#38788]\n\n[#38788]: https://github.com/rust-lang/rust/issues/38788\n\n------------------------\n\nWhen emitting PTX code, all vanilla Rust functions (`fn`) get translated to\n\"device\" functions.

This is\ngenerally unwanted unless you are building another plugin.\n\nThe usual practice is to put compiler plugins in their own crate, separate from\nany `macro_rules!` macros or ordinary Rust code meant to be used by consumers\nof a library.\n\n# Lint plugins\n\nPlugins can extend [Rust's lint\ninfrastructure](../../reference/attributes/diagnostics.md#lint-check-attributes) with\nadditional checks for code style, safety, etc. Now let's write a plugin\n[`lint-plugin-test.rs`](https://github.com/rust-lang/rust/blob/master/src/test/ui-fulldeps/auxiliary/lint-plugin-test.rs)\nthat warns about any item named `lintme`.\n\n```rust,ignore\n#![feature(plugin_registrar)]\n#![feature(box_syntax, rustc_private)]\n\nextern crate rustc_ast;\n\n// Load rustc as a plugin to get macros\nextern crate rustc_driver;\n#[macro_use]\nextern crate rustc_lint;\n#[macro_use]\nextern crate rustc_session;\n\nuse rustc_driver::plugin::Registry;\nuse rustc_lint::{EarlyContext, EarlyLintPass, LintArray, LintContext, LintPass};\nuse rustc_ast::ast;\ndeclare_lint!(TEST_LINT, Warn, \"Warn about items named 'lintme'\");\n\ndeclare_lint_pass!(Pass => [TEST_LINT]);\n\nimpl EarlyLintPass for Pass {\n fn check_item(&mut self, cx: &EarlyContext, it: &ast::Item) {\n if it.ident.name.as_str() == \"lintme\" {\n cx.lint(TEST_LINT, |lint| {\n lint.build(\"item is named 'lintme'\").set_span(it.span).emit()\n });\n }\n }\n}\n\n#[plugin_registrar]\npub fn plugin_registrar(reg: &mut Registry) {\n reg.lint_store.register_lints(&[&TEST_LINT]);\n reg.lint_store.register_early_pass(|| box Pass);\n}\n```\n\nThen code like\n\n```rust,ignore\n#![feature(plugin)]\n#![plugin(lint_plugin_test)]\n\nfn lintme() { }\n```\n\nwill produce a compiler warning:\n\n```txt\nfoo.rs:4:1: 4:16 warning: item is named 'lintme', #[warn(test_lint)] on by default\nfoo.rs:4 fn lintme() { }\n ^~~~~~~~~~~~~~~\n```\n\nThe components of a lint plugin are:\n\n* one or more `declare_lint!` invocations, which define static `Lint` structs;\n\n* a struct holding any state needed by the lint pass (here, none);\n\n* a `LintPass`\n implementation defining how to check each syntax element. A single\n `LintPass` may call `span_lint` for several different `Lint`s, but should\n register them all through the `get_lints` method.\n\nLint passes are syntax traversals, but they run at a late stage of compilation\nwhere type information is available. `rustc`'s [built-in\nlints](https://github.com/rust-lang/rust/blob/master/src/librustc_session/lint/builtin.rs)\nmostly use the same infrastructure as lint plugins, and provide examples of how\nto access type information.\n\nLints defined by plugins are controlled by the usual [attributes and compiler\nflags](../../reference/attributes/diagnostics.md#lint-check-attributes), e.g.\n`#[allow(test_lint)]` or `-A test-lint`. These identifiers are derived from the\nfirst argument to `declare_lint!`, with appropriate case and punctuation\nconversion.\n\nYou can run `rustc -W help foo.rs` to see a list of lints known to `rustc`,\nincluding those provided by plugins loaded by `foo.rs`.\n" } , LintCompletion { label : "concat_idents" , description : "# `concat_idents`\n\nThe tracking issue for this feature is: [#29599]\n\n[#29599]: https://github.com/rust-lang/rust/issues/29599\n\n------------------------\n\nThe `concat_idents` feature adds a macro for concatenating multiple identifiers\ninto one identifier.\n\n## Examples\n\n```rust\n#![feature(concat_idents)]\n\nfn main() {\n fn foobar() -> u32 { 23 }\n let f = concat_idents!(foo, bar);\n assert_eq!(f(), 23);\n}\n```" } , LintCompletion { label : "update_panic_count" , description : "# `update_panic_count`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "fn_traits" , description : "# `fn_traits`\n\nThe tracking issue for this feature is [#29625]\n\nSee Also: [`unboxed_closures`](../language-features/unboxed-closures.md)\n\n[#29625]: https://github.com/rust-lang/rust/issues/29625\n\n----\n\nThe `fn_traits` feature allows for implementation of the [`Fn*`] traits\nfor creating custom closure-like types.\n\n[`Fn*`]: https://doc.rust-lang.org/std/ops/trait.Fn.html\n\n```rust\n#![feature(unboxed_closures)]\n#![feature(fn_traits)]\n\nstruct Adder {\n a: u32\n}\n\nimpl FnOnce<(u32, )> for Adder {\n type Output = u32;\n extern \"rust-call\" fn call_once(self, b: (u32, )) -> Self::Output {\n self.a + b.0\n }\n}\n\nfn main() {\n let adder = Adder { a: 3 };\n assert_eq!(adder(2), 5);\n}\n```\n" } , LintCompletion { label : "try_trait" , description : "# `try_trait`\n\nThe tracking issue for this feature is: [#42327]\n\n[#42327]: https://github.com/rust-lang/rust/issues/42327\n\n------------------------\n\nThis introduces a new trait `Try` for extending the `?` operator to types\nother than `Result` (a part of [RFC 1859]).

The macro is a no-frills\ninterface to LLVM's concept of [module-level inline assembly]. That is,\nall caveats applicable to LLVM's module-level inline assembly apply\nto `global_asm!`.\n\n[module-level inline assembly]: http://llvm.org/docs/LangRef.html#module-level-inline-assembly\n\n`global_asm!` fills a role not currently satisfied by either `asm!`\nor `#[naked]` functions. The programmer has _all_ features of the\nassembler at their disposal. The linker will expect to resolve any\nsymbols defined in the inline assembly, modulo any symbols marked as\nexternal. It also means syntax for directives and assembly follow the\nconventions of the assembler in your toolchain.\n\nA simple usage looks like this:\n\n```rust,ignore\n# #![feature(global_asm)]\n# you also need relevant target_arch cfgs\nglobal_asm!(include_str!(\"something_neato.s\"));\n```\n\nAnd a more complicated usage looks like this:\n\n```rust,ignore\n# #![feature(global_asm)]\n# #![cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n\npub mod sally {\n global_asm!(r#\"\n .global foo\n foo:\n jmp baz\n \"#);\n\n #[no_mangle]\n pub unsafe extern \"C\" fn baz() {}\n}\n\n// the symbols `foo` and `bar` are global, no matter where\n// `global_asm!` was used.\nextern \"C\" {\n fn foo();\n fn bar();\n}\n\npub mod harry {\n global_asm!(r#\"\n .global bar\n bar:\n jmp quux\n \"#);\n\n #[no_mangle]\n pub unsafe extern \"C\" fn quux() {}\n}\n```\n\nYou may use `global_asm!` multiple times, anywhere in your crate, in\nwhatever way suits you. The effect is as if you concatenated all\nusages and placed the larger, single usage in the crate root.\n\n------------------------\n\nIf you don't need quite as much power and flexibility as\n`global_asm!` provides, and you don't mind restricting your inline\nassembly to `fn` bodies only, you might try the\n[asm](asm.md) feature instead.\n" } , LintCompletion { label : "sort_internals" , description : "# `sort_internals`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "test" , description : "# `test`\n\nThe tracking issue for this feature is: None.\n\n------------------------\n\nThe internals of the `test` crate are unstable, behind the `test` flag. The\nmost widely used part of the `test` crate are benchmark tests, which can test\nthe performance of your code. Let's make our `src/lib.rs` look like this\n(comments elided):\n\n```rust,ignore\n#![feature(test)]\n\nextern crate test;\n\npub fn add_two(a: i32) -> i32 {\n a + 2\n}\n\n#[cfg(test)]\nmod tests {\n use super::*;\n use test::Bencher;\n\n #[test]\n fn it_works() {\n assert_eq!(4, add_two(2));\n }\n\n #[bench]\n fn bench_add_two(b: &mut Bencher) {\n b.iter(|| add_two(2));\n }\n}\n```\n\nNote the `test` feature gate, which enables this unstable feature.\n\nWe've imported the `test` crate, which contains our benchmarking support.\nWe have a new function as well, with the `bench` attribute. Unlike regular\ntests, which take no arguments, benchmark tests take a `&mut Bencher`. This\n`Bencher` provides an `iter` method, which takes a closure. This closure\ncontains the code we'd like to benchmark.\n\nWe can run benchmark tests with `cargo bench`:\n\n```bash\n$ cargo bench\n Compiling adder v0.0.1 (file:///home/steve/tmp/adder)\n Running target/release/adder-91b3e234d4ed382a\n\nrunning 2 tests\ntest tests::it_works ... ignored\ntest tests::bench_add_two ... bench: 1 ns/iter (+/- 0)\n\ntest result: ok. 0 passed; 0 failed; 1 ignored; 1 measured\n```\n\nOur non-benchmark test was ignored. You may have noticed that `cargo bench`\ntakes a bit longer than `cargo test`. This is because Rust runs our benchmark\na number of times, and then takes the average. Because we're doing so little\nwork in this example, we have a `1 ns/iter (+/- 0)`, but this would show\nthe variance if there was one.\n\nAdvice on writing benchmarks:\n\n\n* Move setup code outside the `iter` loop; only put the part you want to measure inside\n* Make the code do \"the same thing\" on each iteration; do not accumulate or change state\n* Make the outer function idempotent too; the benchmark runner is likely to run\n it many times\n* Make the inner `iter` loop short and fast so benchmark runs are fast and the\n calibrator can adjust the run-length at fine resolution\n* Make the code in the `iter` loop do something simple, to assist in pinpointing\n performance improvements (or regressions)\n\n## Gotcha: optimizations\n\nThere's another tricky part to writing benchmarks: benchmarks compiled with\noptimizations activated can be dramatically changed by the optimizer so that\nthe benchmark is no longer benchmarking what one expects. For example, the\ncompiler might recognize that some calculation has no external effects and\nremove it entirely.\n\n```rust,ignore\n#![feature(test)]\n\nextern crate test;\nuse test::Bencher;\n\n#[bench]\nfn bench_xor_1000_ints(b: &mut Bencher) {\n b.iter(|| {\n (0..1000).fold(0, |old, new| old ^ new);\n });\n}\n```\n\ngives the following results\n\n```text\nrunning 1 test\ntest bench_xor_1000_ints ... bench: 0 ns/iter (+/- 0)\n\ntest result: ok. 0 passed; 0 failed; 0 ignored; 1 measured\n```\n\nThe benchmarking runner offers two ways to avoid this. Either, the closure that\nthe `iter` method receives can return an arbitrary value which forces the\noptimizer to consider the result used and ensures it cannot remove the\ncomputation entirely. This could be done for the example above by adjusting the\n`b.iter` call to\n\n```rust\n# struct X;\n# impl X { fn iter(&self, _: F) where F: FnMut() -> T {} } let b = X;\nb.iter(|| {\n // Note lack of `;` (could also use an explicit `return`).\n (0..1000).fold(0, |old, new| old ^ new)\n});\n```\n\nOr, the other option is to call the generic `test::black_box` function, which\nis an opaque \"black box\" to the optimizer and so forces it to consider any\nargument as used.\n\n```rust\n#![feature(test)]\n\nextern crate test;\n\n# fn main() {\n# struct X;\n# impl X { fn iter(&self, _: F) where F: FnMut() -> T {} } let b = X;\nb.iter(|| {\n let n = test::black_box(1000);\n\n (0..n).fold(0, |a, b| a ^ b)\n})\n# }\n```\n\nNeither of these read or modify the value, and are very cheap for small values.\nLarger values can be passed indirectly to reduce overhead (e.g.\n`black_box(&huge_struct)`).\n\nPerforming either of the above changes gives the following benchmarking results\n\n```text\nrunning 1 test\ntest bench_xor_1000_ints ... bench: 131 ns/iter (+/- 3)\n\ntest result: ok. 0 passed; 0 failed; 0 ignored; 1 measured\n```\n\nHowever, the optimizer can still modify a testcase in an undesirable manner\neven when using either of the above.\n" } , LintCompletion { label : "windows_stdio" , description : "# `windows_stdio`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "allocator_api" , description : "# `allocator_api`\n\nThe tracking issue for this feature is [#32838]\n\n[#32838]: https://github.com/rust-lang/rust/issues/32838\n\n------------------------\n\nSometimes you want the memory for one collection to use a different\nallocator than the memory for another collection.

Rust supports using inline\nassembly to do this via the `asm!` macro.\n\n# Guide-level explanation\n[guide-level-explanation]: #guide-level-explanation\n\nRust provides support for inline assembly via the `asm!` macro.\nIt can be used to embed handwritten assembly in the assembly output generated by the compiler.\nGenerally this should not be necessary, but might be where the required performance or timing\ncannot be otherwise achieved. Accessing low level hardware primitives, e.g. in kernel code, may also demand this functionality.\n\n> **Note**: the examples here are given in x86/x86-64 assembly, but ARM, AArch64 and RISC-V are also supported.\n\n## Basic usage\n\nLet us start with the simplest possible example:\n\n```rust,allow_fail\n# #![feature(asm)]\nunsafe {\n asm!(\"nop\");\n}\n```\n\nThis will insert a NOP (no operation) instruction into the assembly generated by the compiler.\nNote that all `asm!` invocations have to be inside an `unsafe` block, as they could insert\narbitrary instructions and break various invariants. The instructions to be inserted are listed\nin the first argument of the `asm!` macro as a string literal.\n\n## Inputs and outputs\n\nNow inserting an instruction that does nothing is rather boring. Let us do something that\nactually acts on data:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet x: u64;\nunsafe {\n asm!(\"mov {}, 5\", out(reg) x);\n}\nassert_eq!(x, 5);\n```\n\nThis will write the value `5` into the `u64` variable `x`.\nYou can see that the string literal we use to specify instructions is actually a template string.\nIt is governed by the same rules as Rust [format strings][format-syntax].\nThe arguments that are inserted into the template however look a bit different then you may\nbe familiar with. First we need to specify if the variable is an input or an output of the\ninline assembly. In this case it is an output. We declared this by writing `out`.\nWe also need to specify in what kind of register the assembly expects the variable.\nIn this case we put it in an arbitrary general purpose register by specifying `reg`.\nThe compiler will choose an appropriate register to insert into\nthe template and will read the variable from there after the inline assembly finishes executing.\n\nLet us see another example that also uses an input:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet i: u64 = 3;\nlet o: u64;\nunsafe {\n asm!(\n \"mov {0}, {1}\",\n \"add {0}, {number}\",\n out(reg) o,\n in(reg) i,\n number = const 5,\n );\n}\nassert_eq!(o, 8);\n```\n\nThis will add `5` to the input in variable `i` and write the result to variable `o`.\nThe particular way this assembly does this is first copying the value from `i` to the output,\nand then adding `5` to it.\n\nThe example shows a few things:\n\nFirst, we can see that `asm!` allows multiple template string arguments; each\none is treated as a separate line of assembly code, as if they were all joined\ntogether with newlines between them. This makes it easy to format assembly\ncode.\n\nSecond, we can see that inputs are declared by writing `in` instead of `out`.\n\nThird, one of our operands has a type we haven't seen yet, `const`.\nThis tells the compiler to expand this argument to value directly inside the assembly template.\nThis is only possible for constants and literals.\n\nFourth, we can see that we can specify an argument number, or name as in any format string.\nFor inline assembly templates this is particularly useful as arguments are often used more than once.\nFor more complex inline assembly using this facility is generally recommended, as it improves\nreadability, and allows reordering instructions without changing the argument order.\n\nWe can further refine the above example to avoid the `mov` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut x: u64 = 3;\nunsafe {\n asm!(\"add {0}, {number}\", inout(reg) x, number = const 5);\n}\nassert_eq!(x, 8);\n```\n\nWe can see that `inout` is used to specify an argument that is both input and output.\nThis is different from specifying an input and output separately in that it is guaranteed to assign both to the same register.\n\nIt is also possible to specify different variables for the input and output parts of an `inout` operand:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet x: u64 = 3;\nlet y: u64;\nunsafe {\n asm!(\"add {0}, {number}\", inout(reg) x => y, number = const 5);\n}\nassert_eq!(y, 8);\n```\n\n## Late output operands\n\nThe Rust compiler is conservative with its allocation of operands. It is assumed that an `out`\ncan be written at any time, and can therefore not share its location with any other argument.\nHowever, to guarantee optimal performance it is important to use as few registers as possible,\nso they won't have to be saved and reloaded around the inline assembly block.\nTo achieve this Rust provides a `lateout` specifier. This can be used on any output that is\nwritten only after all inputs have been consumed.\nThere is also a `inlateout` variant of this specifier.\n\nHere is an example where `inlateout` *cannot* be used:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nlet c: u64 = 4;\nunsafe {\n asm!(\n \"add {0}, {1}\",\n \"add {0}, {2}\",\n inout(reg) a,\n in(reg) b,\n in(reg) c,\n );\n}\nassert_eq!(a, 12);\n```\n\nHere the compiler is free to allocate the same register for inputs `b` and `c` since it knows they have the same value. However it must allocate a separate register for `a` since it uses `inout` and not `inlateout`. If `inlateout` was used, then `a` and `c` could be allocated to the same register, in which case the first instruction to overwrite the value of `c` and cause the assembly code to produce the wrong result.\n\nHowever the following example can use `inlateout` since the output is only modified after all input registers have been read:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nunsafe {\n asm!(\"add {0}, {1}\", inlateout(reg) a, in(reg) b);\n}\nassert_eq!(a, 8);\n```\n\nAs you can see, this assembly fragment will still work correctly if `a` and `b` are assigned to the same register.\n\n## Explicit register operands\n\nSome instructions require that the operands be in a specific register.\nTherefore, Rust inline assembly provides some more specific constraint specifiers.\nWhile `reg` is generally available on any architecture, these are highly architecture specific. E.g. for x86 the general purpose registers `eax`, `ebx`, `ecx`, `edx`, `ebp`, `esi`, and `edi`\namong others can be addressed by their name.\n\n```rust,allow_fail,no_run\n# #![feature(asm)]\nlet cmd = 0xd1;\nunsafe {\n asm!(\"out 0x64, eax\", in(\"eax\") cmd);\n}\n```\n\nIn this example we call the `out` instruction to output the content of the `cmd` variable\nto port `0x64`. Since the `out` instruction only accepts `eax` (and its sub registers) as operand\nwe had to use the `eax` constraint specifier.\n\nNote that unlike other operand types, explicit register operands cannot be used in the template string: you can't use `{}` and should write the register name directly instead. Also, they must appear at the end of the operand list after all other operand types.\n\nConsider this example which uses the x86 `mul` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nfn mul(a: u64, b: u64) -> u128 {\n let lo: u64;\n let hi: u64;\n\n unsafe {\n asm!(\n // The x86 mul instruction takes rax as an implicit input and writes\n // the 128-bit result of the multiplication to rax:rdx.\n \"mul {}\",\n in(reg) a,\n inlateout(\"rax\") b => lo,\n lateout(\"rdx\") hi\n );\n }\n\n ((hi as u128) << 64) + lo as u128\n}\n```\n\nThis uses the `mul` instruction to multiply two 64-bit inputs with a 128-bit result.\nThe only explicit operand is a register, that we fill from the variable `a`.\nThe second operand is implicit, and must be the `rax` register, which we fill from the variable `b`.\nThe lower 64 bits of the result are stored in `rax` from which we fill the variable `lo`.\nThe higher 64 bits are stored in `rdx` from which we fill the variable `hi`.\n\n## Clobbered registers\n\nIn many cases inline assembly will modify state that is not needed as an output.\nUsually this is either because we have to use a scratch register in the assembly,\nor instructions modify state that we don't need to further examine.\nThis state is generally referred to as being \"clobbered\".\nWe need to tell the compiler about this since it may need to save and restore this state\naround the inline assembly block.\n\n```rust,allow_fail\n# #![feature(asm)]\nlet ebx: u32;\nlet ecx: u32;\n\nunsafe {\n asm!(\n \"cpuid\",\n // EAX 4 selects the \"Deterministic Cache Parameters\" CPUID leaf\n inout(\"eax\") 4 => _,\n // ECX 0 selects the L0 cache information.\n inout(\"ecx\") 0 => ecx,\n lateout(\"ebx\") ebx,\n lateout(\"edx\") _,\n );\n}\n\nprintln!(\n \"L1 Cache: {}\",\n ((ebx >> 22) + 1) * (((ebx >> 12) & 0x3ff) + 1) * ((ebx & 0xfff) + 1) * (ecx + 1)\n);\n```\n\nIn the example above we use the `cpuid` instruction to get the L1 cache size.\nThis instruction writes to `eax`, `ebx`, `ecx`, and `edx`, but for the cache size we only care about the contents of `ebx` and `ecx`.\n\nHowever we still need to tell the compiler that `eax` and `edx` have been modified so that it can save any values that were in these registers before the asm. This is done by declaring these as outputs but with `_` instead of a variable name, which indicates that the output value is to be discarded.\n\nThis can also be used with a general register class (e.g. `reg`) to obtain a scratch register for use inside the asm code:\n\n```rust,allow_fail\n# #![feature(asm)]\n// Multiply x by 6 using shifts and adds\nlet mut x: u64 = 4;\nunsafe {\n asm!(\n \"mov {tmp}, {x}\",\n \"shl {tmp}, 1\",\n \"shl {x}, 2\",\n \"add {x}, {tmp}\",\n x = inout(reg) x,\n tmp = out(reg) _,\n );\n}\nassert_eq!(x, 4 * 6);\n```\n\n## Symbol operands\n\nA special operand type, `sym`, allows you to use the symbol name of a `fn` or `static` in inline assembly code.\nThis allows you to call a function or access a global variable without needing to keep its address in a register.\n\n```rust,allow_fail\n# #![feature(asm)]\nextern \"C\" fn foo(arg: i32) {\n println!(\"arg = {}\", arg);\n}\n\nfn call_foo(arg: i32) {\n unsafe {\n asm!(\n \"call {}\",\n sym foo,\n // 1st argument in rdi, which is caller-saved\n inout(\"rdi\") arg => _,\n // All caller-saved registers must be marked as clobberred\n out(\"rax\") _, out(\"rcx\") _, out(\"rdx\") _, out(\"rsi\") _,\n out(\"r8\") _, out(\"r9\") _, out(\"r10\") _, out(\"r11\") _,\n out(\"xmm0\") _, out(\"xmm1\") _, out(\"xmm2\") _, out(\"xmm3\") _,\n out(\"xmm4\") _, out(\"xmm5\") _, out(\"xmm6\") _, out(\"xmm7\") _,\n out(\"xmm8\") _, out(\"xmm9\") _, out(\"xmm10\") _, out(\"xmm11\") _,\n out(\"xmm12\") _, out(\"xmm13\") _, out(\"xmm14\") _, out(\"xmm15\") _,\n )\n }\n}\n```\n\nNote that the `fn` or `static` item does not need to be public or `#[no_mangle]`:\nthe compiler will automatically insert the appropriate mangled symbol name into the assembly code.\n\n## Register template modifiers\n\nIn some cases, fine control is needed over the way a register name is formatted when inserted into the template string. This is needed when an architecture's assembly language has several names for the same register, each typically being a \"view\" over a subset of the register (e.g. the low 32 bits of a 64-bit register).\n\nBy default the compiler will always choose the name that refers to the full register size (e.g. `rax` on x86-64, `eax` on x86, etc).\n\nThis default can be overriden by using modifiers on the template string operands, just like you would with format strings:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut x: u16 = 0xab;\n\nunsafe {\n asm!(\"mov {0:h}, {0:l}\", inout(reg_abcd) x);\n}\n\nassert_eq!(x, 0xabab);\n```\n\nIn this example, we use the `reg_abcd` register class to restrict the register allocator to the 4 legacy x86 register (`ax`, `bx`, `cx`, `dx`) of which the first two bytes can be addressed independently.\n\nLet us assume that the register allocator has chosen to allocate `x` in the `ax` register.\nThe `h` modifier will emit the register name for the high byte of that register and the `l` modifier will emit the register name for the low byte. The asm code will therefore be expanded as `mov ah, al` which copies the low byte of the value into the high byte.\n\nIf you use a smaller data type (e.g. `u16`) with an operand and forget the use template modifiers, the compiler will emit a warning and suggest the correct modifier to use.\n\n## Options\n\nBy default, an inline assembly block is treated the same way as an external FFI function call with a custom calling convention: it may read/write memory, have observable side effects, etc. However in many cases, it is desirable to give the compiler more information about what the assembly code is actually doing so that it can optimize better.\n\nLet's take our previous example of an `add` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nunsafe {\n asm!(\n \"add {0}, {1}\",\n inlateout(reg) a, in(reg) b,\n options(pure, nomem, nostack),\n );\n}\nassert_eq!(a, 8);\n```\n\nOptions can be provided as an optional final argument to the `asm!` macro. We specified three options here:\n- `pure` means that the asm code has no observable side effects and that its output depends only on its inputs. This allows the compiler optimizer to call the inline asm fewer times or even eliminate it entirely.\n- `nomem` means that the asm code does not read or write to memory. By default the compiler will assume that inline assembly can read or write any memory address that is accessible to it (e.g. through a pointer passed as an operand, or a global).\n- `nostack` means that the asm code does not push any data onto the stack. This allows the compiler to use optimizations such as the stack red zone on x86-64 to avoid stack pointer adjustments.\n\nThese allow the compiler to better optimize code using `asm!`, for example by eliminating pure `asm!` blocks whose outputs are not needed.\n\nSee the reference for the full list of available options and their effects.\n\n# Reference-level explanation\n[reference-level-explanation]: #reference-level-explanation\n\nInline assembler is implemented as an unsafe macro `asm!()`.\nThe first argument to this macro is a template string literal used to build the final assembly.\nThe following arguments specify input and output operands.\nWhen required, options are specified as the final argument.\n\nThe following ABNF specifies the general syntax:\n\n```ignore\ndir_spec := \"in\" / \"out\" / \"lateout\" / \"inout\" / \"inlateout\"\nreg_spec := / \"\"\noperand_expr := expr / \"_\" / expr \"=>\" expr / expr \"=>\" \"_\"\nreg_operand := dir_spec \"(\" reg_spec \")\" operand_expr\noperand := reg_operand / \"const\" const_expr / \"sym\" path\noption := \"pure\" / \"nomem\" / \"readonly\" / \"preserves_flags\" / \"noreturn\" / \"att_syntax\"\noptions := \"options(\" option *[\",\" option] [\",\"] \")\"\nasm := \"asm!(\" format_string *(\",\" format_string) *(\",\" [ident \"=\"] operand) [\",\" options] [\",\"] \")\"\n```\n\nThe macro will initially be supported only on ARM, AArch64, Hexagon, x86, x86-64 and RISC-V targets. Support for more targets may be added in the future. The compiler will emit an error if `asm!` is used on an unsupported target.\n\n[format-syntax]: https://doc.rust-lang.org/std/fmt/#syntax\n\n## Template string arguments\n\nThe assembler template uses the same syntax as [format strings][format-syntax] (i.e. placeholders are specified by curly braces). The corresponding arguments are accessed in order, by index, or by name. However, implicit named arguments (introduced by [RFC #2795][rfc-2795]) are not supported.\n\nAn `asm!` invocation may have one or more template string arguments; an `asm!` with multiple template string arguments is treated as if all the strings were concatenated with a `\\n` between them. The expected usage is for each template string argument to correspond to a line of assembly code. All template string arguments must appear before any other arguments.\n\nAs with format strings, named arguments must appear after positional arguments. Explicit register operands must appear at the end of the operand list, after named arguments if any.\n\nExplicit register operands cannot be used by placeholders in the template string. All other named and positional operands must appear at least once in the template string, otherwise a compiler error is generated.\n\nThe exact assembly code syntax is target-specific and opaque to the compiler except for the way operands are substituted into the template string to form the code passed to the assembler.\n\nThe 5 targets specified in this RFC (x86, ARM, AArch64, RISC-V, Hexagon) all use the assembly code syntax of the GNU assembler (GAS). On x86, the `.intel_syntax noprefix` mode of GAS is used by default. On ARM, the `.syntax unified` mode is used. These targets impose an additional restriction on the assembly code: any assembler state (e.g. the current section which can be changed with `.section`) must be restored to its original value at the end of the asm string. Assembly code that does not conform to the GAS syntax will result in assembler-specific behavior.\n\n[rfc-2795]: https://github.com/rust-lang/rfcs/pull/2795\n\n## Operand type\n\nSeveral types of operands are supported:\n\n* `in() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain the value of `` at the start of the asm code.\n - The allocated register must contain the same value at the end of the asm code (except if a `lateout` is allocated to the same register).\n* `out() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain an undefined value at the start of the asm code.\n - `` must be a (possibly uninitialized) place expression, to which the contents of the allocated register is written to at the end of the asm code.\n - An underscore (`_`) may be specified instead of an expression, which will cause the contents of the register to be discarded at the end of the asm code (effectively acting as a clobber).\n* `lateout() `\n - Identical to `out` except that the register allocator can reuse a register allocated to an `in`.\n - You should only write to the register after all inputs are read, otherwise you may clobber an input.\n* `inout() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain the value of `` at the start of the asm code.\n - `` must be a mutable initialized place expression, to which the contents of the allocated register is written to at the end of the asm code.\n* `inout() => `\n - Same as `inout` except that the initial value of the register is taken from the value of ``.\n - `` must be a (possibly uninitialized) place expression, to which the contents of the allocated register is written to at the end of the asm code.\n - An underscore (`_`) may be specified instead of an expression for ``, which will cause the contents of the register to be discarded at the end of the asm code (effectively acting as a clobber).\n - `` and `` may have different types.\n* `inlateout() ` / `inlateout() => `\n - Identical to `inout` except that the register allocator can reuse a register allocated to an `in` (this can happen if the compiler knows the `in` has the same initial value as the `inlateout`).\n - You should only write to the register after all inputs are read, otherwise you may clobber an input.\n* `const `\n - `` must be an integer or floating-point constant expression.\n - The value of the expression is formatted as a string and substituted directly into the asm template string.\n* `sym `\n - `` must refer to a `fn` or `static`.\n - A mangled symbol name referring to the item is substituted into the asm template string.\n - The substituted string does not include any modifiers (e.g. GOT, PLT, relocations, etc).\n - `` is allowed to point to a `#[thread_local]` static, in which case the asm code can combine the symbol with relocations (e.g. `@plt`, `@TPOFF`) to read from thread-local data.\n\nOperand expressions are evaluated from left to right, just like function call arguments. After the `asm!` has executed, outputs are written to in left to right order. This is significant if two outputs point to the same place: that place will contain the value of the rightmost output.\n\n## Register operands\n\nInput and output operands can be specified either as an explicit register or as a register class from which the register allocator can select a register. Explicit registers are specified as string literals (e.g. `\"eax\"`) while register classes are specified as identifiers (e.g. `reg`). Using string literals for register names enables support for architectures that use special characters in register names, such as MIPS (`$0`, `$1`, etc).\n\nNote that explicit registers treat register aliases (e.g. `r14` vs `lr` on ARM) and smaller views of a register (e.g. `eax` vs `rax`) as equivalent to the base register. It is a compile-time error to use the same explicit register for two input operands or two output operands. Additionally, it is also a compile-time error to use overlapping registers (e.g. ARM VFP) in input operands or in output operands.\n\nOnly the following types are allowed as operands for inline assembly:\n- Integers (signed and unsigned)\n- Floating-point numbers\n- Pointers (thin only)\n- Function pointers\n- SIMD vectors (structs defined with `#[repr(simd)]` and which implement `Copy`). This includes architecture-specific vector types defined in `std::arch` such as `__m128` (x86) or `int8x16_t` (ARM).\n\nHere is the list of currently supported register classes:\n\n| Architecture | Register class | Registers | LLVM constraint code |\n| ------------ | -------------- | --------- | -------------------- |\n| x86 | `reg` | `ax`, `bx`, `cx`, `dx`, `si`, `di`, `r[8-15]` (x86-64 only) | `r` |\n| x86 | `reg_abcd` | `ax`, `bx`, `cx`, `dx` | `Q` |\n| x86-32 | `reg_byte` | `al`, `bl`, `cl`, `dl`, `ah`, `bh`, `ch`, `dh` | `q` |\n| x86-64 | `reg_byte` | `al`, `bl`, `cl`, `dl`, `sil`, `dil`, `r[8-15]b`, `ah`\\*, `bh`\\*, `ch`\\*, `dh`\\* | `q` |\n| x86 | `xmm_reg` | `xmm[0-7]` (x86) `xmm[0-15]` (x86-64) | `x` |\n| x86 | `ymm_reg` | `ymm[0-7]` (x86) `ymm[0-15]` (x86-64) | `x` |\n| x86 | `zmm_reg` | `zmm[0-7]` (x86) `zmm[0-31]` (x86-64) | `v` |\n| x86 | `kreg` | `k[1-7]` | `Yk` |\n| AArch64 | `reg` | `x[0-28]`, `x30` | `r` |\n| AArch64 | `vreg` | `v[0-31]` | `w` |\n| AArch64 | `vreg_low16` | `v[0-15]` | `x` |\n| ARM | `reg` | `r[0-5]` `r7`\\*, `r[8-10]`, `r11`\\*, `r12`, `r14` | `r` |\n| ARM (Thumb) | `reg_thumb` | `r[0-r7]` | `l` |\n| ARM (ARM) | `reg_thumb` | `r[0-r10]`, `r12`, `r14` | `l` |\n| ARM | `sreg` | `s[0-31]` | `t` |\n| ARM | `sreg_low16` | `s[0-15]` | `x` |\n| ARM | `dreg` | `d[0-31]` | `w` |\n| ARM | `dreg_low16` | `d[0-15]` | `t` |\n| ARM | `dreg_low8` | `d[0-8]` | `x` |\n| ARM | `qreg` | `q[0-15]` | `w` |\n| ARM | `qreg_low8` | `q[0-7]` | `t` |\n| ARM | `qreg_low4` | `q[0-3]` | `x` |\n| NVPTX | `reg16` | None\\* | `h` |\n| NVPTX | `reg32` | None\\* | `r` |\n| NVPTX | `reg64` | None\\* | `l` |\n| RISC-V | `reg` | `x1`, `x[5-7]`, `x[9-15]`, `x[16-31]` (non-RV32E) | `r` |\n| RISC-V | `freg` | `f[0-31]` | `f` |\n| Hexagon | `reg` | `r[0-28]` | `r` |\n\n> **Note**: On x86 we treat `reg_byte` differently from `reg` because the compiler can allocate `al` and `ah` separately whereas `reg` reserves the whole register.\n>\n> Note #2: On x86-64 the high byte registers (e.g. `ah`) are only available when used as an explicit register. Specifying the `reg_byte` register class for an operand will always allocate a low byte register.\n>\n> Note #3: NVPTX doesn't have a fixed register set, so named registers are not supported.\n>\n> Note #4: On ARM the frame pointer is either `r7` or `r11` depending on the platform.\n\nAdditional register classes may be added in the future based on demand (e.g. MMX, x87, etc).\n\nEach register class has constraints on which value types they can be used with. This is necessary because the way a value is loaded into a register depends on its type. For example, on big-endian systems, loading a `i32x4` and a `i8x16` into a SIMD register may result in different register contents even if the byte-wise memory representation of both values is identical. The availability of supported types for a particular register class may depend on what target features are currently enabled.\n\n| Architecture | Register class | Target feature | Allowed types |\n| ------------ | -------------- | -------------- | ------------- |\n| x86-32 | `reg` | None | `i16`, `i32`, `f32` |\n| x86-64 | `reg` | None | `i16`, `i32`, `f32`, `i64`, `f64` |\n| x86 | `reg_byte` | None | `i8` |\n| x86 | `xmm_reg` | `sse` | `i32`, `f32`, `i64`, `f64`,

The only exception is the `freg` register class on RISC-V where `f32` values are NaN-boxed in a `f64` as required by the RISC-V architecture.\n\nWhen separate input and output expressions are specified for an `inout` operand, both expressions must have the same type. The only exception is if both operands are pointers or integers, in which case they are only required to have the same size. This restriction exists because the register allocators in LLVM and GCC sometimes cannot handle tied operands with different types.\n\n## Register names\n\nSome registers have multiple names.

The frame pointer cannot be used as an input or output. |\n| ARM | `r6` | `r6` is used internally by LLVM as a base pointer and therefore cannot be used as an input or output. |\n| x86 | `k0` | This is a constant zero register which can't be modified. |\n| x86 | `ip` | This is the program counter, not a real register. |\n| x86 | `mm[0-7]` | MMX registers are not currently supported (but may be in the future). |\n| x86 | `st([0-7])` | x87 registers are not currently supported (but may be in the future). |\n| AArch64 | `xzr` | This is a constant zero register which can't be modified. |\n| ARM | `pc` | This is the program counter, not a real register. |\n| RISC-V | `x0` | This is a constant zero register which can't be modified. |\n| RISC-V | `gp`, `tp` | These registers are reserved and cannot be used as inputs or outputs. |\n| Hexagon | `lr` | This is the link register which cannot be used as an input or output. |\n\n## Template modifiers\n\nThe placeholders can be augmented by modifiers which are specified after the `:` in the curly braces. These modifiers do not affect register allocation, but change the way operands are formatted when inserted into the template string. Only one modifier is allowed per template placeholder.\n\nThe supported modifiers are a subset of LLVM's (and GCC's) [asm template argument modifiers][llvm-argmod], but do not use the same letter codes.\n\n| Architecture | Register class | Modifier | Example output | LLVM modifier |\n| ------------ | -------------- | -------- | -------------- | ------------- |\n| x86-32 | `reg` | None | `eax` | `k` |\n| x86-64 | `reg` | None | `rax` | `q` |\n| x86-32 | `reg_abcd` | `l` | `al` | `b` |\n| x86-64 | `reg` | `l` | `al` | `b` |\n| x86 | `reg_abcd` | `h` | `ah` | `h` |\n| x86 | `reg` | `x` | `ax` | `w` |\n| x86 | `reg` | `e` | `eax` | `k` |\n| x86-64 | `reg` | `r` | `rax` | `q` |\n| x86 | `reg_byte` | None | `al` / `ah` | None |\n| x86 | `xmm_reg` | None | `xmm0` | `x` |\n| x86 | `ymm_reg` | None | `ymm0` | `t` |\n| x86 | `zmm_reg` | None | `zmm0` | `g` |\n| x86 | `*mm_reg` | `x` | `xmm0` | `x` |\n| x86 | `*mm_reg` | `y` | `ymm0` | `t` |\n| x86 | `*mm_reg` | `z` | `zmm0` | `g` |\n| x86 | `kreg` | None | `k1` | None |\n| AArch64 | `reg` | None | `x0` | `x` |\n| AArch64 | `reg` | `w` | `w0` | `w` |\n| AArch64 | `reg` | `x` | `x0` | `x` |\n| AArch64 | `vreg` | None | `v0` | None |\n| AArch64 | `vreg` | `v` | `v0` | None |\n| AArch64 | `vreg` | `b` | `b0` | `b` |\n| AArch64 | `vreg` | `h` | `h0` | `h` |\n| AArch64 | `vreg` | `s` | `s0` | `s` |\n| AArch64 | `vreg` | `d` | `d0` | `d` |\n| AArch64 | `vreg` | `q` | `q0` | `q` |\n| ARM | `reg` | None | `r0` | None |\n| ARM | `sreg` | None | `s0` | None |\n| ARM | `dreg` | None | `d0` | `P` |\n| ARM | `qreg` | None | `q0` | `q` |\n| ARM | `qreg` | `e` / `f` | `d0` / `d1` | `e` / `f` |\n| NVPTX | `reg16` | None | `rs0` | None |\n| NVPTX | `reg32` | None | `r0` | None |\n| NVPTX | `reg64` | None | `rd0` | None |\n| RISC-V | `reg` | None | `x1` | None |\n| RISC-V | `freg` | None | `f0` | None |\n| Hexagon | `reg` | None | `r0` | None |\n\n> Notes:\n> - on ARM `e` / `f`: this prints the low or high doubleword register name of a NEON quad (128-bit) register.\n> - on x86: our behavior for `reg` with no modifiers differs from what GCC does. GCC will infer the modifier based on the operand value type, while we default to the full register size.\n> - on x86 `xmm_reg`: the `x`, `t` and `g` LLVM modifiers are not yet implemented in LLVM (they are supported by GCC only), but this should be a simple change.\n\nAs stated in the previous section, passing an input value smaller than the register width will result in the upper bits of the register containing undefined values. This is not a problem if the inline asm only accesses the lower bits of the register, which can be done by using a template modifier to use a subregister name in the asm code (e.g. `ax` instead of `rax`). Since this an easy pitfall, the compiler will suggest a template modifier to use where appropriate given the input type. If all references to an operand already have modifiers then the warning is suppressed for that operand.\n\n[llvm-argmod]: http://llvm.org/docs/LangRef.html#asm-template-argument-modifiers\n\n## Options\n\nFlags are used to further influence the behavior of the inline assembly block.\nCurrently the following options are defined:\n- `pure`: The `asm` block has no side effects, and its outputs depend only on its direct inputs (i.e. the values themselves, not what they point to) or values read from memory (unless the `nomem` options is also set). This allows the compiler to execute the `asm` block fewer times than specified in the program (e.g. by hoisting it out of a loop) or even eliminate it entirely if the outputs are not used.\n- `nomem`: The `asm` blocks does not read or write to any memory. This allows the compiler to cache the values of modified global variables in registers across the `asm` block since it knows that they are not read or written to by the `asm`.\n- `readonly`: The `asm` block does not write to any memory. This allows the compiler to cache the values of unmodified global variables in registers across the `asm` block since it knows that they are not written to by the `asm`.\n- `preserves_flags`: The `asm` block does not modify the flags register (defined in the rules below). This allows the compiler to avoid recomputing the condition flags after the `asm` block.\n- `noreturn`: The `asm` block never returns, and its return type is defined as `!` (never). Behavior is undefined if execution falls through past the end of the asm code. A `noreturn` asm block behaves just like a function which doesn't return; notably, local variables in scope are not dropped before it is invoked.\n- `nostack`: The `asm` block does not push data to the stack, or write to the stack red-zone (if supported by the target). If this option is *not* used then the stack pointer is guaranteed to be suitably aligned (according to the target ABI) for a function call.\n- `att_syntax`: This option is only valid on x86, and causes the assembler to use the `.att_syntax prefix` mode of the GNU assembler. Register operands are substituted in with a leading `%`.\n\nThe compiler performs some additional checks on options:\n- The `nomem` and `readonly` options are mutually exclusive: it is a compile-time error to specify both.\n- The `pure` option must be combined with either the `nomem` or `readonly` options, otherwise a compile-time error is emitted.\n- It is a compile-time error to specify `pure` on an asm block with no outputs or only discarded outputs (`_`).\n- It is a compile-time error to specify `noreturn` on an asm block with outputs.\n\n## Rules for inline assembly\n\n- Any registers not specified as inputs will contain an undefined value on entry to the asm block.\n - An \"undefined value\" in the context of inline assembly means that the register can (non-deterministically) have any one of the possible values allowed by the architecture. Notably it is not the same as an LLVM `undef` which can have a different value every time you read it (since such a concept does not exist in assembly code).\n- Any registers not specified as outputs must have the same value upon exiting the asm block as they had on entry, otherwise behavior is undefined.\n - This only applies to registers which can be specified as an input or output. Other registers follow target-specific rules.\n - Note that a `lateout` may be allocated to the same register as an `in`, in which case this rule does not apply. Code should not rely on this however since it depends on the results of register allocation.\n- Behavior is undefined if execution unwinds out of an asm block.\n - This also applies if the assembly code calls a function which then unwinds.\n- The set of memory locations that assembly code is allowed the read and write are the same as those allowed for an FFI function.\n - Refer to the unsafe code guidelines for the exact rules.\n - If the `readonly` option is set, then only memory reads are allowed.\n - If the `nomem` option is set then no reads or writes to memory are allowed.\n - These rules do not apply to memory which is private to the asm code, such as stack space allocated within the asm block.\n- The compiler cannot assume that the instructions in the asm are the ones that will actually end up executed.\n - This effectively means that the compiler must treat the `asm!` as a black box and only take the interface specification into account, not the instructions themselves.\n - Runtime code patching is allowed, via target-specific mechanisms (outside the scope of this RFC).\n- Unless the `nostack` option is set, asm code is allowed to use stack space below the stack pointer.\n - On entry to the asm block the stack pointer is guaranteed to be suitably aligned (according to the target ABI) for a function call.\n - You are responsible for making sure you don't overflow the stack (e.g. use stack probing to ensure you hit a guard page).\n - You should adjust the stack pointer when allocating stack memory as required by the target ABI.\n - The stack pointer must be restored to its original value before leaving the asm block.\n- If the `noreturn` option is set then behavior is undefined if execution falls through to the end of the asm block.\n- If the `pure` option is set then behavior is undefined if the `asm` has side-effects other than its direct outputs. Behavior is also undefined if two executions of the `asm` code with the same inputs result in different outputs.\n - When used with the `nomem` option, \"inputs\" are just the direct inputs of the `asm!`.\n - When used with the `readonly` option, \"inputs\" comprise the direct inputs of the `asm!` and any memory that the `asm!` block is allowed to read.\n- These flags registers must be restored upon exiting the asm block if the `preserves_flags` option is set:\n - x86\n - Status flags in `EFLAGS` (CF, PF, AF, ZF, SF, OF).\n - Floating-point status word (all).\n - Floating-point exception flags in `MXCSR` (PE, UE, OE, ZE, DE, IE).\n - ARM\n - Condition flags in `CPSR` (N, Z, C, V)\n - Saturation flag in `CPSR` (Q)\n - Greater than or equal flags in `CPSR` (GE).\n - Condition flags in `FPSCR` (N, Z, C, V)\n - Saturation flag in `FPSCR` (QC)\n - Floating-point exception flags in `FPSCR` (IDC, IXC, UFC, OFC, DZC, IOC).\n - AArch64\n - Condition flags (`NZCV` register).\n - Floating-point status (`FPSR` register).\n - RISC-V\n - Floating-point exception flags in `fcsr` (`fflags`).\n- On x86, the direction flag (DF in `EFLAGS`) is clear on entry to an asm block and must be clear on exit.\n - Behavior is undefined if the direction flag is set on exiting an asm block.\n- The requirement of restoring the stack pointer and non-output registers to their original value only applies when exiting an `asm!` block.\n - This means that `asm!` blocks that never return (even if not marked `noreturn`) don't need to preserve these registers.\n - When returning to a different `asm!` block than you entered (e.g. for context switching), these registers must contain the value they had upon entering the `asm!` block that you are *exiting*.\n - You cannot exit an `asm!` block that has not been entered. Neither can you exit an `asm!` block that has already been exited.\n - You are responsible for switching any target-specific state (e.g. thread-local storage, stack bounds).\n - The set of memory locations that you may access is the intersection of those allowed by the `asm!` blocks you entered and exited.\n- You cannot assume that an `asm!` block will appear exactly once in the output binary. The compiler is allowed to instantiate multiple copies of the `asm!` block, for example when the function containing it is inlined in multiple places.\n - As a consequence, you should only use [local labels] inside inline assembly code. Defining symbols in assembly code may lead to assembler and/or linker errors due to duplicate symbol definitions.\n\n> **Note**: As a general rule, the flags covered by `preserves_flags` are those which are *not* preserved when performing a function call.\n\n[local labels]: https://sourceware.org/binutils/docs/as/Symbol-Names.html#Local-Labels\n" } , LintCompletion { label : "is_sorted" ,

This is useful for very low level programming, where\nwhich register you use is important:\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# unsafe fn read_byte_in(port: u16) -> u8 {\nlet result: u8;\nllvm_asm!(\"in %dx, %al\" : \"={al}\"(result) : \"{dx}\"(port));\nresult\n# }\n```\n\n## Clobbers\n\nSome instructions modify registers which might otherwise have held\ndifferent values so we use the clobbers list to indicate to the\ncompiler not to assume any values loaded into those registers will\nstay valid.\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# fn main() { unsafe {\n// Put the value 0x200 in eax:\nllvm_asm!(\"mov $$0x200, %eax\" : /* no outputs */ : /* no inputs */ : \"eax\");\n# } }\n# #[cfg(not(any(target_arch = \"x86\", target_arch = \"x86_64\")))]\n# fn main() {}\n```\n\nInput and output registers need not be listed since that information\nis already communicated by the given constraints. Otherwise, any other\nregisters used either implicitly or explicitly should be listed.\n\nIf the assembly changes the condition code register `cc` should be\nspecified as one of the clobbers. Similarly, if the assembly modifies\nmemory, `memory` should also be specified.\n\n## Options\n\nThe last section, `options` is specific to Rust. The format is comma\nseparated literal strings (i.e. `:\"foo\", \"bar\", \"baz\"`). It's used to\nspecify some extra info about the inline assembly:\n\nCurrent valid options are:\n\n1. *volatile* - specifying this is analogous to\n `__asm__ __volatile__ (...)` in gcc/clang.\n2. *alignstack* - certain instructions expect the stack to be\n aligned a certain way (i.e. SSE) and specifying this indicates to\n the compiler to insert its usual stack alignment code\n3. *intel* - use intel syntax instead of the default AT&T.\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# fn main() {\nlet result: i32;\nunsafe {\n llvm_asm!(\"mov eax, 2\" : \"={eax}\"(result) : : : \"intel\")\n}\nprintln!(\"eax is currently {}\", result);\n# }\n# #[cfg(not(any(target_arch = \"x86\", target_arch = \"x86_64\")))]\n# fn main() {}\n```\n\n## More Information\n\nThe current implementation of the `llvm_asm!` macro is a direct binding to [LLVM's\ninline assembler expressions][llvm-docs], so be sure to check out [their\ndocumentation as well][llvm-docs] for more information about clobbers,\nconstraints, etc.\n\n[llvm-docs]: http://llvm.org/docs/LangRef.html#inline-assembler-expressions\n\nIf you need more power and don't mind losing some of the niceties of\n`llvm_asm!`, check out [global_asm](global-asm.md).\n" } ] ; +pub ( crate ) const UNSTABLE_FEATURE_DESCRIPTOR : & [ LintCompletion ] = & [ LintCompletion { label : "crate_visibility_modifier" , description : "# `crate_visibility_modifier`\n\nThe tracking issue for this feature is: [#53120]\n\n[#53120]: https://github.com/rust-lang/rust/issues/53120\n\n-----\n\nThe `crate_visibility_modifier` feature allows the `crate` keyword to be used\nas a visibility modifier synonymous to `pub(crate)`, indicating that a type\n(function, _&c._) is to be visible to the entire enclosing crate, but not to\nother crates.\n\n```rust\n#![feature(crate_visibility_modifier)]\n\ncrate struct Foo {\n bar: usize,\n}\n```\n" } , LintCompletion { label : "abi_thiscall" , description : "# `abi_thiscall`\n\nThe tracking issue for this feature is: [#42202]\n\n[#42202]: https://github.com/rust-lang/rust/issues/42202\n\n------------------------\n\nThe MSVC ABI on x86 Windows uses the `thiscall` calling convention for C++\ninstance methods by default; it is identical to the usual (C) calling\nconvention on x86 Windows except that the first parameter of the method,\nthe `this` pointer, is passed in the ECX register.\n" } , LintCompletion { label : "infer_static_outlives_requirements" , description : "# `infer_static_outlives_requirements`\n\nThe tracking issue for this feature is: [#54185]\n\n[#54185]: https://github.com/rust-lang/rust/issues/54185\n\n------------------------\nThe `infer_static_outlives_requirements` feature indicates that certain\n`'static` outlives requirements can be inferred by the compiler rather than\nstating them explicitly.\n\nNote: It is an accompanying feature to `infer_outlives_requirements`,\nwhich must be enabled to infer outlives requirements.\n\nFor example, currently generic struct definitions that contain\nreferences, require where-clauses of the form T: 'static.

A generator is a \"resumable function\" that syntactically\nresembles a closure but compiles to much different semantics in the compiler\nitself. The primary feature of a generator is that it can be suspended during\nexecution to be resumed at a later date. Generators use the `yield` keyword to\n\"return\", and then the caller can `resume` a generator to resume execution just\nafter the `yield` keyword.\n\nGenerators are an extra-unstable feature in the compiler right now. Added in\n[RFC 2033] they're mostly intended right now as a information/constraint\ngathering phase. The intent is that experimentation can happen on the nightly\ncompiler before actual stabilization. A further RFC will be required to\nstabilize generators/coroutines and will likely contain at least a few small\ntweaks to the overall design.\n\n[RFC 2033]: https://github.com/rust-lang/rfcs/pull/2033\n\nA syntactical example of a generator is:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::{Generator, GeneratorState};\nuse std::pin::Pin;\n\nfn main() {\n let mut generator = || {\n yield 1;\n return \"foo\"\n };\n\n match Pin::new(&mut generator).resume(()) {\n GeneratorState::Yielded(1) => {}\n _ => panic!(\"unexpected value from resume\"),\n }\n match Pin::new(&mut generator).resume(()) {\n GeneratorState::Complete(\"foo\") => {}\n _ => panic!(\"unexpected value from resume\"),\n }\n}\n```\n\nGenerators are closure-like literals which can contain a `yield` statement. The\n`yield` statement takes an optional expression of a value to yield out of the\ngenerator. All generator literals implement the `Generator` trait in the\n`std::ops` module. The `Generator` trait has one main method, `resume`, which\nresumes execution of the generator at the previous suspension point.\n\nAn example of the control flow of generators is that the following example\nprints all numbers in order:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::Generator;\nuse std::pin::Pin;\n\nfn main() {\n let mut generator = || {\n println!(\"2\");\n yield;\n println!(\"4\");\n };\n\n println!(\"1\");\n Pin::new(&mut generator).resume(());\n println!(\"3\");\n Pin::new(&mut generator).resume(());\n println!(\"5\");\n}\n```\n\nAt this time the main intended use case of generators is an implementation\nprimitive for async/await syntax, but generators will likely be extended to\nergonomic implementations of iterators and other primitives in the future.\nFeedback on the design and usage is always appreciated!\n\n### The `Generator` trait\n\nThe `Generator` trait in `std::ops` currently looks like:\n\n```rust\n# #![feature(arbitrary_self_types, generator_trait)]\n# use std::ops::GeneratorState;\n# use std::pin::Pin;\n\npub trait Generator {\n type Yield;\n type Return;\n fn resume(self: Pin<&mut Self>, resume: R) -> GeneratorState;\n}\n```\n\nThe `Generator::Yield` type is the type of values that can be yielded with the\n`yield` statement. The `Generator::Return` type is the returned type of the\ngenerator. This is typically the last expression in a generator's definition or\nany value passed to `return` in a generator. The `resume` function is the entry\npoint for executing the `Generator` itself.\n\nThe return value of `resume`, `GeneratorState`, looks like:\n\n```rust\npub enum GeneratorState {\n Yielded(Y),\n Complete(R),\n}\n```\n\nThe `Yielded` variant indicates that the generator can later be resumed. This\ncorresponds to a `yield` point in a generator. The `Complete` variant indicates\nthat the generator is complete and cannot be resumed again. Calling `resume`\nafter a generator has returned `Complete` will likely result in a panic of the\nprogram.\n\n### Closure-like semantics\n\nThe closure-like syntax for generators alludes to the fact that they also have\nclosure-like semantics. Namely:\n\n* When created, a generator executes no code. A closure literal does not\n actually execute any of the closure's code on construction, and similarly a\n generator literal does not execute any code inside the generator when\n constructed.\n\n* Generators can capture outer variables by reference or by move, and this can\n be tweaked with the `move` keyword at the beginning of the closure. Like\n closures all generators will have an implicit environment which is inferred by\n the compiler. Outer variables can be moved into a generator for use as the\n generator progresses.\n\n* Generator literals produce a value with a unique type which implements the\n `std::ops::Generator` trait. This allows actual execution of the generator\n through the `Generator::resume` method as well as also naming it in return\n types and such.\n\n* Traits like `Send` and `Sync` are automatically implemented for a `Generator`\n depending on the captured variables of the environment. Unlike closures,\n generators also depend on variables live across suspension points. This means\n that although the ambient environment may be `Send` or `Sync`, the generator\n itself may not be due to internal variables live across `yield` points being\n not-`Send` or not-`Sync`. Note that generators do\n not implement traits like `Copy` or `Clone` automatically.\n\n* Whenever a generator is dropped it will drop all captured environment\n variables.\n\n### Generators as state machines\n\nIn the compiler, generators are currently compiled as state machines. Each\n`yield` expression will correspond to a different state that stores all live\nvariables over that suspension point. Resumption of a generator will dispatch on\nthe current state and then execute internally until a `yield` is reached, at\nwhich point all state is saved off in the generator and a value is returned.\n\nLet's take a look at an example to see what's going on here:\n\n```rust\n#![feature(generators, generator_trait)]\n\nuse std::ops::Generator;\nuse std::pin::Pin;\n\nfn main() {\n let ret = \"foo\";\n let mut generator = move || {\n yield 1;\n return ret\n };\n\n Pin::new(&mut generator).resume(());\n Pin::new(&mut generator).resume(());\n}\n```\n\nThis generator literal will compile down to something similar to:\n\n```rust\n#![feature(arbitrary_self_types, generators, generator_trait)]\n\nuse std::ops::{Generator, GeneratorState};\nuse std::pin::Pin;\n\nfn main() {\n let ret = \"foo\";\n let mut generator = {\n enum __Generator {\n Start(&'static str),\n Yield1(&'static str),\n Done,\n }\n\n impl Generator for __Generator {\n type Yield = i32;\n type Return = &'static str;\n\n fn resume(mut self: Pin<&mut Self>, resume: ()) -> GeneratorState {\n use std::mem;\n match mem::replace(&mut *self, __Generator::Done) {\n __Generator::Start(s) => {\n *self = __Generator::Yield1(s);\n GeneratorState::Yielded(1)\n }\n\n __Generator::Yield1(s) => {\n *self = __Generator::Done;\n GeneratorState::Complete(s)\n }\n\n __Generator::Done => {\n panic!(\"generator resumed after completion\")\n }\n }\n }\n }\n\n __Generator::Start(ret)\n };\n\n Pin::new(&mut generator).resume(());\n Pin::new(&mut generator).resume(());\n}\n```\n\nNotably here we can see that the compiler is generating a fresh type,\n`__Generator` in this case. This type has a number of states (represented here\nas an `enum`) corresponding to each of the conceptual states of the generator.\nAt the beginning we're closing over our outer variable `foo` and then that\nvariable is also live over the `yield` point, so it's stored in both states.\n\nWhen the generator starts it'll immediately yield 1, but it saves off its state\njust before it does so indicating that it has reached the yield point.

The syntax isn't final, either. We may need an alternative syntax for Rust 2015 because, in Rust 2015, expressions like `[e; dyn(1)]` would be ambiguous. One possible alternative proposed in the RFC is `[e; n]`: if `n` captures one or more local variables, then it is considered as `[e; dyn n]`.\n\n## Advisory on stack usage\n\nIt's advised not to casually use the `#![feature(unsized_locals)]` feature. Typical use-cases are:\n\n- When you need a by-value trait objects.\n- When you really need a fast allocation of small temporary arrays.\n\nAnother pitfall is repetitive allocation and temporaries. Currently the compiler simply extends the stack frame every time it encounters an unsized assignment. So for example, the code\n\n```rust\n#![feature(unsized_locals)]\n\nfn main() {\n let x: Box<[i32]> = Box::new([1, 2, 3, 4, 5]);\n let _x = {{{{{{{{{{*x}}}}}}}}}};\n}\n```\n\nand the code\n\n```rust\n#![feature(unsized_locals)]\n\nfn main() {\n for _ in 0..10 {\n let x: Box<[i32]> = Box::new([1, 2, 3, 4, 5]);\n let _x = *x;\n }\n}\n```\n\nwill unnecessarily extend the stack frame.\n" } , LintCompletion { label : "or_patterns" , description : "# `or_patterns`\n\nThe tracking issue for this feature is: [#54883]\n\n[#54883]: https://github.com/rust-lang/rust/issues/54883\n\n------------------------\n\nThe `or_pattern` language feature allows `|` to be arbitrarily nested within\na pattern, for example, `Some(A(0) | B(1 | 2))` becomes a valid pattern.\n\n## Examples\n\n```rust,ignore\n#![feature(or_patterns)]\n\npub enum Foo {\n Bar,\n Baz,\n Quux,\n}\n\npub fn example(maybe_foo: Option) {\n match maybe_foo {\n Some(Foo::Bar | Foo::Baz) => {\n println!(\"The value contained `Bar` or `Baz`\");\n }\n Some(_) => {\n println!(\"The value did not contain `Bar` or `Baz`\");\n }\n None => {\n println!(\"The value was `None`\");\n }\n }\n}\n```\n" } , LintCompletion { label : "member_constraints" , description : "# `member_constraints`\n\nThe tracking issue for this feature is: [#61997]\n\n[#61997]: https://github.com/rust-lang/rust/issues/61997\n\n------------------------\n\nThe `member_constraints` feature gate lets you use `impl Trait` syntax with\nmultiple unrelated lifetime parameters.\n\nA simple example is:\n\n```rust\n#![feature(member_constraints)]\n\ntrait Trait<'a, 'b> { }\nimpl Trait<'_, '_> for T {}\n\nfn foo<'a, 'b>(x: &'a u32, y: &'b u32) -> impl Trait<'a, 'b> {\n (x, y)\n}\n\nfn main() { }\n```\n\nWithout the `member_constraints` feature gate, the above example is an\nerror because both `'a` and `'b` appear in the impl Trait bounds, but\nneither outlives the other.\n" } , LintCompletion { label : "optin_builtin_traits" , description : "# `optin_builtin_traits`\n\nThe tracking issue for this feature is [#13231] \n\n[#13231]: https://github.com/rust-lang/rust/issues/13231\n\n----\n\nThe `optin_builtin_traits` feature gate allows you to define auto traits.\n\nAuto traits, like [`Send`] or [`Sync`] in the standard library, are marker traits\nthat are automatically implemented for every type, unless the type, or a type it contains, \nhas explicitly opted out via a negative impl.

These automatic impls contain a where clause for each field\nof the form `T: AutoTrait`, where `T` is the type of the field and\n`AutoTrait` is the auto trait in question. As an example, consider the\nstruct `List` and the auto trait `Send`:\n\n```rust\nstruct List {\n data: T,\n next: Option>>,\n}\n```\n\nPresuming that there is no explicit impl of `Send` for `List`, the\ncompiler will supply an automatic impl of the form:\n\n```rust\nstruct List {\n data: T,\n next: Option>>,\n}\n\nunsafe impl Send for List\nwhere\n T: Send, // from the field `data`\n Option>>: Send, // from the field `next`\n{ }\n```\n\nExplicit impls may be either positive or negative. They take the form:\n\n```rust,ignore\nimpl<...> AutoTrait for StructName<..> { }\nimpl<...> !AutoTrait for StructName<..> { }\n```\n\n## Coinduction: Auto traits permit cyclic matching\n\nUnlike ordinary trait matching, auto traits are **coinductive**. This\nmeans, in short, that cycles which occur in trait matching are\nconsidered ok. As an example, consider the recursive struct `List`\nintroduced in the previous section. In attempting to determine whether\n`List: Send`, we would wind up in a cycle: to apply the impl, we must\nshow that `Option>: Send`, which will in turn require\n`Box: Send` and then finally `List: Send` again. Under ordinary\ntrait matching, this cycle would be an error, but for an auto trait it\nis considered a successful match.\n\n## Items\n\nAuto traits cannot have any trait items, such as methods or associated types. This ensures that we can generate default implementations.\n\n## Supertraits\n\nAuto traits cannot have supertraits.

The marker is the attribute `#[lang = \"...\"]` and there are\nvarious different values of `...`, i.e. various different 'lang\nitems'.\n\nFor example, `Box` pointers require two lang items, one for allocation\nand one for deallocation. A freestanding program that uses the `Box`\nsugar for dynamic allocations via `malloc` and `free`:\n\n```rust,ignore\n#![feature(lang_items, box_syntax, start, libc, core_intrinsics)]\n#![no_std]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\nextern crate libc;\n\n#[lang = \"owned_box\"]\npub struct Box(*mut T);\n\n#[lang = \"exchange_malloc\"]\nunsafe fn allocate(size: usize, _align: usize) -> *mut u8 {\n let p = libc::malloc(size as libc::size_t) as *mut u8;\n\n // Check if `malloc` failed:\n if p as usize == 0 {\n intrinsics::abort();\n }\n\n p\n}\n\n#[lang = \"box_free\"]\nunsafe fn box_free(ptr: *mut T) {\n libc::free(ptr as *mut libc::c_void)\n}\n\n#[start]\nfn main(_argc: isize, _argv: *const *const u8) -> isize {\n let _x = box 1;\n\n 0\n}\n\n#[lang = \"eh_personality\"] extern fn rust_eh_personality() {}\n#[lang = \"panic_impl\"] extern fn rust_begin_panic(info: &PanicInfo) -> ! { unsafe { intrinsics::abort() } }\n#[no_mangle] pub extern fn rust_eh_register_frames () {}\n#[no_mangle] pub extern fn rust_eh_unregister_frames () {}\n```\n\nNote the use of `abort`: the `exchange_malloc` lang item is assumed to\nreturn a valid pointer, and so needs to do the check internally.\n\nOther features provided by lang items include:\n\n- overloadable operators via traits: the traits corresponding to the\n `==`, `<`, dereferencing (`*`) and `+` (etc.) operators are all\n marked with lang items; those specific four are `eq`, `ord`,\n `deref`, and `add` respectively.\n- stack unwinding and general failure; the `eh_personality`,\n `panic` and `panic_bounds_checks` lang items.\n- the traits in `std::marker` used to indicate types of\n various kinds; lang items `send`, `sync` and `copy`.\n- the marker types and variance indicators found in\n `std::marker`; lang items `covariant_type`,\n `contravariant_lifetime`, etc.\n\nLang items are loaded lazily by the compiler; e.g. if one never uses\n`Box` then there is no need to define functions for `exchange_malloc`\nand `box_free`. `rustc` will emit an error when an item is needed\nbut not found in the current crate or any that it depends on.\n\nMost lang items are defined by `libcore`, but if you're trying to build\nan executable without the standard library, you'll run into the need\nfor lang items. The rest of this page focuses on this use-case, even though\nlang items are a bit broader than that.\n\n### Using libc\n\nIn order to build a `#[no_std]` executable we will need libc as a dependency.\nWe can specify this using our `Cargo.toml` file:\n\n```toml\n[dependencies]\nlibc = { version = \"0.2.14\", default-features = false }\n```\n\nNote that the default features have been disabled. This is a critical step -\n**the default features of libc include the standard library and so must be\ndisabled.**\n\n### Writing an executable without stdlib\n\nControlling the entry point is possible in two ways: the `#[start]` attribute,\nor overriding the default shim for the C `main` function with your own.\n\nThe function marked `#[start]` is passed the command line parameters\nin the same format as C:\n\n```rust,ignore\n#![feature(lang_items, core_intrinsics)]\n#![feature(start)]\n#![no_std]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\n// Pull in the system libc library for what crt0.o likely requires.\nextern crate libc;\n\n// Entry point for this program.\n#[start]\nfn start(_argc: isize, _argv: *const *const u8) -> isize {\n 0\n}\n\n// These functions are used by the compiler, but not\n// for a bare-bones hello world. These are normally\n// provided by libstd.\n#[lang = \"eh_personality\"]\n#[no_mangle]\npub extern fn rust_eh_personality() {\n}\n\n#[lang = \"panic_impl\"]\n#[no_mangle]\npub extern fn rust_begin_panic(info: &PanicInfo) -> ! {\n unsafe { intrinsics::abort() }\n}\n```\n\nTo override the compiler-inserted `main` shim, one has to disable it\nwith `#![no_main]` and then create the appropriate symbol with the\ncorrect ABI and the correct name, which requires overriding the\ncompiler's name mangling too:\n\n```rust,ignore\n#![feature(lang_items, core_intrinsics)]\n#![feature(start)]\n#![no_std]\n#![no_main]\nuse core::intrinsics;\nuse core::panic::PanicInfo;\n\n// Pull in the system libc library for what crt0.o likely requires.\nextern crate libc;\n\n// Entry point for this program.\n#[no_mangle] // ensure that this symbol is called `main` in the output\npub extern fn main(_argc: i32, _argv: *const *const u8) -> i32 {\n 0\n}\n\n// These functions are used by the compiler, but not\n// for a bare-bones hello world.

You may observe this via linker error messages\nsuch as \"```undefined reference to `__rust_probestack'```\".\n\n## More about the language items\n\nThe compiler currently makes a few assumptions about symbols which are\navailable in the executable to call. Normally these functions are provided by\nthe standard library, but without it you must define your own. These symbols\nare called \"language items\", and they each have an internal name, and then a\nsignature that an implementation must conform to.\n\nThe first of these functions, `rust_eh_personality`, is used by the failure\nmechanisms of the compiler. This is often mapped to GCC's personality function\n(see the [libstd implementation][unwind] for more information), but crates\nwhich do not trigger a panic can be assured that this function is never\ncalled.

Negative impls are a commitment not to implement the given trait for the named types.\n\n## Orphan and overlap rules\n\nNegative impls must obey the same orphan rules as a positive impl. This implies you cannot add a negative impl for types defined in upstream crates and so forth.\n\nSimilarly, negative impls cannot overlap with positive impls, again using the same \"overlap\" check that we ordinarily use to determine if two impls overlap. (Note that positive impls typically cannot overlap with one another either, except as permitted by specialization.)\n\n## Interaction with auto traits\n\nDeclaring a negative impl `impl !SomeAutoTrait for SomeType` for an\nauto-trait serves two purposes:\n\n* as with any trait, it declares that `SomeType` will never implement `SomeAutoTrait`;\n* it disables the automatic `SomeType: SomeAutoTrait` impl that would otherwise have been generated.\n\nNote that, at present, there is no way to indicate that a given type\ndoes not implement an auto trait *but that it may do so in the\nfuture*. For ordinary types, this is done by simply not declaring any\nimpl at all, but that is not an option for auto traits. A workaround\nis that one could embed a marker type as one of the fields, where the\nmarker type is `!AutoTrait`.\n\n## Immediate uses\n\nNegative impls are used to declare that `&T: !DerefMut` and `&mut T: !Clone`, as required to fix the soundness of `Pin` described in [#66544](https://github.com/rust-lang/rust/issues/66544).\n\nThis serves two purposes:\n\n* For proving the correctness of unsafe code, we can use that impl as evidence that no `DerefMut` or `Clone` impl exists.\n* It prevents downstream crates from creating such impls.\n" } , LintCompletion { label : "abi_ptx" , description : "# `abi_ptx`\n\nThe tracking issue for this feature is: [#38788]\n\n[#38788]: https://github.com/rust-lang/rust/issues/38788\n\n------------------------\n\nWhen emitting PTX code, all vanilla Rust functions (`fn`) get translated to\n\"device\" functions.

This is\ngenerally unwanted unless you are building another plugin.\n\nThe usual practice is to put compiler plugins in their own crate, separate from\nany `macro_rules!` macros or ordinary Rust code meant to be used by consumers\nof a library.\n\n# Lint plugins\n\nPlugins can extend [Rust's lint\ninfrastructure](../../reference/attributes/diagnostics.md#lint-check-attributes) with\nadditional checks for code style, safety, etc. Now let's write a plugin\n[`lint-plugin-test.rs`](https://github.com/rust-lang/rust/blob/master/src/test/ui-fulldeps/auxiliary/lint-plugin-test.rs)\nthat warns about any item named `lintme`.\n\n```rust,ignore\n#![feature(plugin_registrar)]\n#![feature(box_syntax, rustc_private)]\n\nextern crate rustc_ast;\n\n// Load rustc as a plugin to get macros\nextern crate rustc_driver;\n#[macro_use]\nextern crate rustc_lint;\n#[macro_use]\nextern crate rustc_session;\n\nuse rustc_driver::plugin::Registry;\nuse rustc_lint::{EarlyContext, EarlyLintPass, LintArray, LintContext, LintPass};\nuse rustc_ast::ast;\ndeclare_lint!(TEST_LINT, Warn, \"Warn about items named 'lintme'\");\n\ndeclare_lint_pass!(Pass => [TEST_LINT]);\n\nimpl EarlyLintPass for Pass {\n fn check_item(&mut self, cx: &EarlyContext, it: &ast::Item) {\n if it.ident.name.as_str() == \"lintme\" {\n cx.lint(TEST_LINT, |lint| {\n lint.build(\"item is named 'lintme'\").set_span(it.span).emit()\n });\n }\n }\n}\n\n#[plugin_registrar]\npub fn plugin_registrar(reg: &mut Registry) {\n reg.lint_store.register_lints(&[&TEST_LINT]);\n reg.lint_store.register_early_pass(|| box Pass);\n}\n```\n\nThen code like\n\n```rust,ignore\n#![feature(plugin)]\n#![plugin(lint_plugin_test)]\n\nfn lintme() { }\n```\n\nwill produce a compiler warning:\n\n```txt\nfoo.rs:4:1: 4:16 warning: item is named 'lintme', #[warn(test_lint)] on by default\nfoo.rs:4 fn lintme() { }\n ^~~~~~~~~~~~~~~\n```\n\nThe components of a lint plugin are:\n\n* one or more `declare_lint!` invocations, which define static `Lint` structs;\n\n* a struct holding any state needed by the lint pass (here, none);\n\n* a `LintPass`\n implementation defining how to check each syntax element. A single\n `LintPass` may call `span_lint` for several different `Lint`s, but should\n register them all through the `get_lints` method.\n\nLint passes are syntax traversals, but they run at a late stage of compilation\nwhere type information is available. `rustc`'s [built-in\nlints](https://github.com/rust-lang/rust/blob/master/src/librustc_session/lint/builtin.rs)\nmostly use the same infrastructure as lint plugins, and provide examples of how\nto access type information.\n\nLints defined by plugins are controlled by the usual [attributes and compiler\nflags](../../reference/attributes/diagnostics.md#lint-check-attributes), e.g.\n`#[allow(test_lint)]` or `-A test-lint`. These identifiers are derived from the\nfirst argument to `declare_lint!`, with appropriate case and punctuation\nconversion.\n\nYou can run `rustc -W help foo.rs` to see a list of lints known to `rustc`,\nincluding those provided by plugins loaded by `foo.rs`.\n" } , LintCompletion { label : "concat_idents" , description : "# `concat_idents`\n\nThe tracking issue for this feature is: [#29599]\n\n[#29599]: https://github.com/rust-lang/rust/issues/29599\n\n------------------------\n\nThe `concat_idents` feature adds a macro for concatenating multiple identifiers\ninto one identifier.\n\n## Examples\n\n```rust\n#![feature(concat_idents)]\n\nfn main() {\n fn foobar() -> u32 { 23 }\n let f = concat_idents!(foo, bar);\n assert_eq!(f(), 23);\n}\n```" } , LintCompletion { label : "update_panic_count" , description : "# `update_panic_count`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "fn_traits" , description : "# `fn_traits`\n\nThe tracking issue for this feature is [#29625]\n\nSee Also: [`unboxed_closures`](../language-features/unboxed-closures.md)\n\n[#29625]: https://github.com/rust-lang/rust/issues/29625\n\n----\n\nThe `fn_traits` feature allows for implementation of the [`Fn*`] traits\nfor creating custom closure-like types.\n\n[`Fn*`]: https://doc.rust-lang.org/std/ops/trait.Fn.html\n\n```rust\n#![feature(unboxed_closures)]\n#![feature(fn_traits)]\n\nstruct Adder {\n a: u32\n}\n\nimpl FnOnce<(u32, )> for Adder {\n type Output = u32;\n extern \"rust-call\" fn call_once(self, b: (u32, )) -> Self::Output {\n self.a + b.0\n }\n}\n\nfn main() {\n let adder = Adder { a: 3 };\n assert_eq!(adder(2), 5);\n}\n```\n" } , LintCompletion { label : "try_trait" , description : "# `try_trait`\n\nThe tracking issue for this feature is: [#42327]\n\n[#42327]: https://github.com/rust-lang/rust/issues/42327\n\n------------------------\n\nThis introduces a new trait `Try` for extending the `?` operator to types\nother than `Result` (a part of [RFC 1859]).

The macro is a no-frills\ninterface to LLVM's concept of [module-level inline assembly]. That is,\nall caveats applicable to LLVM's module-level inline assembly apply\nto `global_asm!`.\n\n[module-level inline assembly]: http://llvm.org/docs/LangRef.html#module-level-inline-assembly\n\n`global_asm!` fills a role not currently satisfied by either `asm!`\nor `#[naked]` functions. The programmer has _all_ features of the\nassembler at their disposal. The linker will expect to resolve any\nsymbols defined in the inline assembly, modulo any symbols marked as\nexternal. It also means syntax for directives and assembly follow the\nconventions of the assembler in your toolchain.\n\nA simple usage looks like this:\n\n```rust,ignore\n# #![feature(global_asm)]\n# you also need relevant target_arch cfgs\nglobal_asm!(include_str!(\"something_neato.s\"));\n```\n\nAnd a more complicated usage looks like this:\n\n```rust,ignore\n# #![feature(global_asm)]\n# #![cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n\npub mod sally {\n global_asm!(r#\"\n .global foo\n foo:\n jmp baz\n \"#);\n\n #[no_mangle]\n pub unsafe extern \"C\" fn baz() {}\n}\n\n// the symbols `foo` and `bar` are global, no matter where\n// `global_asm!` was used.\nextern \"C\" {\n fn foo();\n fn bar();\n}\n\npub mod harry {\n global_asm!(r#\"\n .global bar\n bar:\n jmp quux\n \"#);\n\n #[no_mangle]\n pub unsafe extern \"C\" fn quux() {}\n}\n```\n\nYou may use `global_asm!` multiple times, anywhere in your crate, in\nwhatever way suits you. The effect is as if you concatenated all\nusages and placed the larger, single usage in the crate root.\n\n------------------------\n\nIf you don't need quite as much power and flexibility as\n`global_asm!` provides, and you don't mind restricting your inline\nassembly to `fn` bodies only, you might try the\n[asm](asm.md) feature instead.\n" } , LintCompletion { label : "sort_internals" , description : "# `sort_internals`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "test" , description : "# `test`\n\nThe tracking issue for this feature is: None.\n\n------------------------\n\nThe internals of the `test` crate are unstable, behind the `test` flag. The\nmost widely used part of the `test` crate are benchmark tests, which can test\nthe performance of your code. Let's make our `src/lib.rs` look like this\n(comments elided):\n\n```rust,ignore\n#![feature(test)]\n\nextern crate test;\n\npub fn add_two(a: i32) -> i32 {\n a + 2\n}\n\n#[cfg(test)]\nmod tests {\n use super::*;\n use test::Bencher;\n\n #[test]\n fn it_works() {\n assert_eq!(4, add_two(2));\n }\n\n #[bench]\n fn bench_add_two(b: &mut Bencher) {\n b.iter(|| add_two(2));\n }\n}\n```\n\nNote the `test` feature gate, which enables this unstable feature.\n\nWe've imported the `test` crate, which contains our benchmarking support.\nWe have a new function as well, with the `bench` attribute. Unlike regular\ntests, which take no arguments, benchmark tests take a `&mut Bencher`. This\n`Bencher` provides an `iter` method, which takes a closure. This closure\ncontains the code we'd like to benchmark.\n\nWe can run benchmark tests with `cargo bench`:\n\n```bash\n$ cargo bench\n Compiling adder v0.0.1 (file:///home/steve/tmp/adder)\n Running target/release/adder-91b3e234d4ed382a\n\nrunning 2 tests\ntest tests::it_works ... ignored\ntest tests::bench_add_two ... bench: 1 ns/iter (+/- 0)\n\ntest result: ok. 0 passed; 0 failed; 1 ignored; 1 measured\n```\n\nOur non-benchmark test was ignored. You may have noticed that `cargo bench`\ntakes a bit longer than `cargo test`. This is because Rust runs our benchmark\na number of times, and then takes the average. Because we're doing so little\nwork in this example, we have a `1 ns/iter (+/- 0)`, but this would show\nthe variance if there was one.\n\nAdvice on writing benchmarks:\n\n\n* Move setup code outside the `iter` loop; only put the part you want to measure inside\n* Make the code do \"the same thing\" on each iteration; do not accumulate or change state\n* Make the outer function idempotent too; the benchmark runner is likely to run\n it many times\n* Make the inner `iter` loop short and fast so benchmark runs are fast and the\n calibrator can adjust the run-length at fine resolution\n* Make the code in the `iter` loop do something simple, to assist in pinpointing\n performance improvements (or regressions)\n\n## Gotcha: optimizations\n\nThere's another tricky part to writing benchmarks: benchmarks compiled with\noptimizations activated can be dramatically changed by the optimizer so that\nthe benchmark is no longer benchmarking what one expects. For example, the\ncompiler might recognize that some calculation has no external effects and\nremove it entirely.\n\n```rust,ignore\n#![feature(test)]\n\nextern crate test;\nuse test::Bencher;\n\n#[bench]\nfn bench_xor_1000_ints(b: &mut Bencher) {\n b.iter(|| {\n (0..1000).fold(0, |old, new| old ^ new);\n });\n}\n```\n\ngives the following results\n\n```text\nrunning 1 test\ntest bench_xor_1000_ints ... bench: 0 ns/iter (+/- 0)\n\ntest result: ok. 0 passed; 0 failed; 0 ignored; 1 measured\n```\n\nThe benchmarking runner offers two ways to avoid this. Either, the closure that\nthe `iter` method receives can return an arbitrary value which forces the\noptimizer to consider the result used and ensures it cannot remove the\ncomputation entirely. This could be done for the example above by adjusting the\n`b.iter` call to\n\n```rust\n# struct X;\n# impl X { fn iter(&self, _: F) where F: FnMut() -> T {} } let b = X;\nb.iter(|| {\n // Note lack of `;` (could also use an explicit `return`).\n (0..1000).fold(0, |old, new| old ^ new)\n});\n```\n\nOr, the other option is to call the generic `test::black_box` function, which\nis an opaque \"black box\" to the optimizer and so forces it to consider any\nargument as used.\n\n```rust\n#![feature(test)]\n\nextern crate test;\n\n# fn main() {\n# struct X;\n# impl X { fn iter(&self, _: F) where F: FnMut() -> T {} } let b = X;\nb.iter(|| {\n let n = test::black_box(1000);\n\n (0..n).fold(0, |a, b| a ^ b)\n})\n# }\n```\n\nNeither of these read or modify the value, and are very cheap for small values.\nLarger values can be passed indirectly to reduce overhead (e.g.\n`black_box(&huge_struct)`).\n\nPerforming either of the above changes gives the following benchmarking results\n\n```text\nrunning 1 test\ntest bench_xor_1000_ints ... bench: 131 ns/iter (+/- 3)\n\ntest result: ok. 0 passed; 0 failed; 0 ignored; 1 measured\n```\n\nHowever, the optimizer can still modify a testcase in an undesirable manner\neven when using either of the above.\n" } , LintCompletion { label : "windows_stdio" , description : "# `windows_stdio`\n\nThis feature is internal to the Rust compiler and is not intended for general use.\n\n------------------------\n" } , LintCompletion { label : "allocator_api" , description : "# `allocator_api`\n\nThe tracking issue for this feature is [#32838]\n\n[#32838]: https://github.com/rust-lang/rust/issues/32838\n\n------------------------\n\nSometimes you want the memory for one collection to use a different\nallocator than the memory for another collection.

Rust supports using inline\nassembly to do this via the `asm!` macro.\n\n# Guide-level explanation\n[guide-level-explanation]: #guide-level-explanation\n\nRust provides support for inline assembly via the `asm!` macro.\nIt can be used to embed handwritten assembly in the assembly output generated by the compiler.\nGenerally this should not be necessary, but might be where the required performance or timing\ncannot be otherwise achieved. Accessing low level hardware primitives, e.g. in kernel code, may also demand this functionality.\n\n> **Note**: the examples here are given in x86/x86-64 assembly, but other architectures are also supported.\n\nInline assembly is currently supported on the following architectures:\n- x86 and x86-64\n- ARM\n- AArch64\n- RISC-V\n- NVPTX\n- Hexagon\n\n## Basic usage\n\nLet us start with the simplest possible example:\n\n```rust,allow_fail\n# #![feature(asm)]\nunsafe {\n asm!(\"nop\");\n}\n```\n\nThis will insert a NOP (no operation) instruction into the assembly generated by the compiler.\nNote that all `asm!` invocations have to be inside an `unsafe` block, as they could insert\narbitrary instructions and break various invariants. The instructions to be inserted are listed\nin the first argument of the `asm!` macro as a string literal.\n\n## Inputs and outputs\n\nNow inserting an instruction that does nothing is rather boring. Let us do something that\nactually acts on data:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet x: u64;\nunsafe {\n asm!(\"mov {}, 5\", out(reg) x);\n}\nassert_eq!(x, 5);\n```\n\nThis will write the value `5` into the `u64` variable `x`.\nYou can see that the string literal we use to specify instructions is actually a template string.\nIt is governed by the same rules as Rust [format strings][format-syntax].\nThe arguments that are inserted into the template however look a bit different then you may\nbe familiar with. First we need to specify if the variable is an input or an output of the\ninline assembly. In this case it is an output. We declared this by writing `out`.\nWe also need to specify in what kind of register the assembly expects the variable.\nIn this case we put it in an arbitrary general purpose register by specifying `reg`.\nThe compiler will choose an appropriate register to insert into\nthe template and will read the variable from there after the inline assembly finishes executing.\n\nLet us see another example that also uses an input:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet i: u64 = 3;\nlet o: u64;\nunsafe {\n asm!(\n \"mov {0}, {1}\",\n \"add {0}, {number}\",\n out(reg) o,\n in(reg) i,\n number = const 5,\n );\n}\nassert_eq!(o, 8);\n```\n\nThis will add `5` to the input in variable `i` and write the result to variable `o`.\nThe particular way this assembly does this is first copying the value from `i` to the output,\nand then adding `5` to it.\n\nThe example shows a few things:\n\nFirst, we can see that `asm!` allows multiple template string arguments; each\none is treated as a separate line of assembly code, as if they were all joined\ntogether with newlines between them. This makes it easy to format assembly\ncode.\n\nSecond, we can see that inputs are declared by writing `in` instead of `out`.\n\nThird, one of our operands has a type we haven't seen yet, `const`.\nThis tells the compiler to expand this argument to value directly inside the assembly template.\nThis is only possible for constants and literals.\n\nFourth, we can see that we can specify an argument number, or name as in any format string.\nFor inline assembly templates this is particularly useful as arguments are often used more than once.\nFor more complex inline assembly using this facility is generally recommended, as it improves\nreadability, and allows reordering instructions without changing the argument order.\n\nWe can further refine the above example to avoid the `mov` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut x: u64 = 3;\nunsafe {\n asm!(\"add {0}, {number}\", inout(reg) x, number = const 5);\n}\nassert_eq!(x, 8);\n```\n\nWe can see that `inout` is used to specify an argument that is both input and output.\nThis is different from specifying an input and output separately in that it is guaranteed to assign both to the same register.\n\nIt is also possible to specify different variables for the input and output parts of an `inout` operand:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet x: u64 = 3;\nlet y: u64;\nunsafe {\n asm!(\"add {0}, {number}\", inout(reg) x => y, number = const 5);\n}\nassert_eq!(y, 8);\n```\n\n## Late output operands\n\nThe Rust compiler is conservative with its allocation of operands. It is assumed that an `out`\ncan be written at any time, and can therefore not share its location with any other argument.\nHowever, to guarantee optimal performance it is important to use as few registers as possible,\nso they won't have to be saved and reloaded around the inline assembly block.\nTo achieve this Rust provides a `lateout` specifier. This can be used on any output that is\nwritten only after all inputs have been consumed.\nThere is also a `inlateout` variant of this specifier.\n\nHere is an example where `inlateout` *cannot* be used:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nlet c: u64 = 4;\nunsafe {\n asm!(\n \"add {0}, {1}\",\n \"add {0}, {2}\",\n inout(reg) a,\n in(reg) b,\n in(reg) c,\n );\n}\nassert_eq!(a, 12);\n```\n\nHere the compiler is free to allocate the same register for inputs `b` and `c` since it knows they have the same value. However it must allocate a separate register for `a` since it uses `inout` and not `inlateout`. If `inlateout` was used, then `a` and `c` could be allocated to the same register, in which case the first instruction to overwrite the value of `c` and cause the assembly code to produce the wrong result.\n\nHowever the following example can use `inlateout` since the output is only modified after all input registers have been read:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nunsafe {\n asm!(\"add {0}, {1}\", inlateout(reg) a, in(reg) b);\n}\nassert_eq!(a, 8);\n```\n\nAs you can see, this assembly fragment will still work correctly if `a` and `b` are assigned to the same register.\n\n## Explicit register operands\n\nSome instructions require that the operands be in a specific register.\nTherefore, Rust inline assembly provides some more specific constraint specifiers.\nWhile `reg` is generally available on any architecture, these are highly architecture specific. E.g. for x86 the general purpose registers `eax`, `ebx`, `ecx`, `edx`, `ebp`, `esi`, and `edi`\namong others can be addressed by their name.\n\n```rust,allow_fail,no_run\n# #![feature(asm)]\nlet cmd = 0xd1;\nunsafe {\n asm!(\"out 0x64, eax\", in(\"eax\") cmd);\n}\n```\n\nIn this example we call the `out` instruction to output the content of the `cmd` variable\nto port `0x64`. Since the `out` instruction only accepts `eax` (and its sub registers) as operand\nwe had to use the `eax` constraint specifier.\n\nNote that unlike other operand types, explicit register operands cannot be used in the template string: you can't use `{}` and should write the register name directly instead. Also, they must appear at the end of the operand list after all other operand types.\n\nConsider this example which uses the x86 `mul` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nfn mul(a: u64, b: u64) -> u128 {\n let lo: u64;\n let hi: u64;\n\n unsafe {\n asm!(\n // The x86 mul instruction takes rax as an implicit input and writes\n // the 128-bit result of the multiplication to rax:rdx.\n \"mul {}\",\n in(reg) a,\n inlateout(\"rax\") b => lo,\n lateout(\"rdx\") hi\n );\n }\n\n ((hi as u128) << 64) + lo as u128\n}\n```\n\nThis uses the `mul` instruction to multiply two 64-bit inputs with a 128-bit result.\nThe only explicit operand is a register, that we fill from the variable `a`.\nThe second operand is implicit, and must be the `rax` register, which we fill from the variable `b`.\nThe lower 64 bits of the result are stored in `rax` from which we fill the variable `lo`.\nThe higher 64 bits are stored in `rdx` from which we fill the variable `hi`.\n\n## Clobbered registers\n\nIn many cases inline assembly will modify state that is not needed as an output.\nUsually this is either because we have to use a scratch register in the assembly,\nor instructions modify state that we don't need to further examine.\nThis state is generally referred to as being \"clobbered\".\nWe need to tell the compiler about this since it may need to save and restore this state\naround the inline assembly block.\n\n```rust,allow_fail\n# #![feature(asm)]\nlet ebx: u32;\nlet ecx: u32;\n\nunsafe {\n asm!(\n \"cpuid\",\n // EAX 4 selects the \"Deterministic Cache Parameters\" CPUID leaf\n inout(\"eax\") 4 => _,\n // ECX 0 selects the L0 cache information.\n inout(\"ecx\") 0 => ecx,\n lateout(\"ebx\") ebx,\n lateout(\"edx\") _,\n );\n}\n\nprintln!(\n \"L1 Cache: {}\",\n ((ebx >> 22) + 1) * (((ebx >> 12) & 0x3ff) + 1) * ((ebx & 0xfff) + 1) * (ecx + 1)\n);\n```\n\nIn the example above we use the `cpuid` instruction to get the L1 cache size.\nThis instruction writes to `eax`, `ebx`, `ecx`, and `edx`, but for the cache size we only care about the contents of `ebx` and `ecx`.\n\nHowever we still need to tell the compiler that `eax` and `edx` have been modified so that it can save any values that were in these registers before the asm. This is done by declaring these as outputs but with `_` instead of a variable name, which indicates that the output value is to be discarded.\n\nThis can also be used with a general register class (e.g. `reg`) to obtain a scratch register for use inside the asm code:\n\n```rust,allow_fail\n# #![feature(asm)]\n// Multiply x by 6 using shifts and adds\nlet mut x: u64 = 4;\nunsafe {\n asm!(\n \"mov {tmp}, {x}\",\n \"shl {tmp}, 1\",\n \"shl {x}, 2\",\n \"add {x}, {tmp}\",\n x = inout(reg) x,\n tmp = out(reg) _,\n );\n}\nassert_eq!(x, 4 * 6);\n```\n\n## Symbol operands\n\nA special operand type, `sym`, allows you to use the symbol name of a `fn` or `static` in inline assembly code.\nThis allows you to call a function or access a global variable without needing to keep its address in a register.\n\n```rust,allow_fail\n# #![feature(asm)]\nextern \"C\" fn foo(arg: i32) {\n println!(\"arg = {}\", arg);\n}\n\nfn call_foo(arg: i32) {\n unsafe {\n asm!(\n \"call {}\",\n sym foo,\n // 1st argument in rdi, which is caller-saved\n inout(\"rdi\") arg => _,\n // All caller-saved registers must be marked as clobberred\n out(\"rax\") _, out(\"rcx\") _, out(\"rdx\") _, out(\"rsi\") _,\n out(\"r8\") _, out(\"r9\") _, out(\"r10\") _, out(\"r11\") _,\n out(\"xmm0\") _, out(\"xmm1\") _, out(\"xmm2\") _, out(\"xmm3\") _,\n out(\"xmm4\") _, out(\"xmm5\") _, out(\"xmm6\") _, out(\"xmm7\") _,\n out(\"xmm8\") _, out(\"xmm9\") _, out(\"xmm10\") _, out(\"xmm11\") _,\n out(\"xmm12\") _, out(\"xmm13\") _, out(\"xmm14\") _, out(\"xmm15\") _,\n )\n }\n}\n```\n\nNote that the `fn` or `static` item does not need to be public or `#[no_mangle]`:\nthe compiler will automatically insert the appropriate mangled symbol name into the assembly code.\n\n## Register template modifiers\n\nIn some cases, fine control is needed over the way a register name is formatted when inserted into the template string. This is needed when an architecture's assembly language has several names for the same register, each typically being a \"view\" over a subset of the register (e.g. the low 32 bits of a 64-bit register).\n\nBy default the compiler will always choose the name that refers to the full register size (e.g. `rax` on x86-64, `eax` on x86, etc).\n\nThis default can be overriden by using modifiers on the template string operands, just like you would with format strings:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut x: u16 = 0xab;\n\nunsafe {\n asm!(\"mov {0:h}, {0:l}\", inout(reg_abcd) x);\n}\n\nassert_eq!(x, 0xabab);\n```\n\nIn this example, we use the `reg_abcd` register class to restrict the register allocator to the 4 legacy x86 register (`ax`, `bx`, `cx`, `dx`) of which the first two bytes can be addressed independently.\n\nLet us assume that the register allocator has chosen to allocate `x` in the `ax` register.\nThe `h` modifier will emit the register name for the high byte of that register and the `l` modifier will emit the register name for the low byte. The asm code will therefore be expanded as `mov ah, al` which copies the low byte of the value into the high byte.\n\nIf you use a smaller data type (e.g. `u16`) with an operand and forget the use template modifiers, the compiler will emit a warning and suggest the correct modifier to use.\n\n## Options\n\nBy default, an inline assembly block is treated the same way as an external FFI function call with a custom calling convention: it may read/write memory, have observable side effects, etc. However in many cases, it is desirable to give the compiler more information about what the assembly code is actually doing so that it can optimize better.\n\nLet's take our previous example of an `add` instruction:\n\n```rust,allow_fail\n# #![feature(asm)]\nlet mut a: u64 = 4;\nlet b: u64 = 4;\nunsafe {\n asm!(\n \"add {0}, {1}\",\n inlateout(reg) a, in(reg) b,\n options(pure, nomem, nostack),\n );\n}\nassert_eq!(a, 8);\n```\n\nOptions can be provided as an optional final argument to the `asm!` macro. We specified three options here:\n- `pure` means that the asm code has no observable side effects and that its output depends only on its inputs. This allows the compiler optimizer to call the inline asm fewer times or even eliminate it entirely.\n- `nomem` means that the asm code does not read or write to memory. By default the compiler will assume that inline assembly can read or write any memory address that is accessible to it (e.g. through a pointer passed as an operand, or a global).\n- `nostack` means that the asm code does not push any data onto the stack. This allows the compiler to use optimizations such as the stack red zone on x86-64 to avoid stack pointer adjustments.\n\nThese allow the compiler to better optimize code using `asm!`, for example by eliminating pure `asm!` blocks whose outputs are not needed.\n\nSee the reference for the full list of available options and their effects.\n\n# Reference-level explanation\n[reference-level-explanation]: #reference-level-explanation\n\nInline assembler is implemented as an unsafe macro `asm!()`.\nThe first argument to this macro is a template string literal used to build the final assembly.\nThe following arguments specify input and output operands.\nWhen required, options are specified as the final argument.\n\nThe following ABNF specifies the general syntax:\n\n```ignore\ndir_spec := \"in\" / \"out\" / \"lateout\" / \"inout\" / \"inlateout\"\nreg_spec := / \"\"\noperand_expr := expr / \"_\" / expr \"=>\" expr / expr \"=>\" \"_\"\nreg_operand := dir_spec \"(\" reg_spec \")\" operand_expr\noperand := reg_operand / \"const\" const_expr / \"sym\" path\noption := \"pure\" / \"nomem\" / \"readonly\" / \"preserves_flags\" / \"noreturn\" / \"att_syntax\"\noptions := \"options(\" option *[\",\" option] [\",\"] \")\"\nasm := \"asm!(\" format_string *(\",\" format_string) *(\",\" [ident \"=\"] operand) [\",\" options] [\",\"] \")\"\n```\n\nThe macro will initially be supported only on ARM, AArch64, Hexagon, x86, x86-64 and RISC-V targets. Support for more targets may be added in the future. The compiler will emit an error if `asm!` is used on an unsupported target.\n\n[format-syntax]: https://doc.rust-lang.org/std/fmt/#syntax\n\n## Template string arguments\n\nThe assembler template uses the same syntax as [format strings][format-syntax] (i.e. placeholders are specified by curly braces). The corresponding arguments are accessed in order, by index, or by name. However, implicit named arguments (introduced by [RFC #2795][rfc-2795]) are not supported.\n\nAn `asm!` invocation may have one or more template string arguments; an `asm!` with multiple template string arguments is treated as if all the strings were concatenated with a `\\n` between them. The expected usage is for each template string argument to correspond to a line of assembly code. All template string arguments must appear before any other arguments.\n\nAs with format strings, named arguments must appear after positional arguments. Explicit register operands must appear at the end of the operand list, after named arguments if any.\n\nExplicit register operands cannot be used by placeholders in the template string. All other named and positional operands must appear at least once in the template string, otherwise a compiler error is generated.\n\nThe exact assembly code syntax is target-specific and opaque to the compiler except for the way operands are substituted into the template string to form the code passed to the assembler.\n\nThe 5 targets specified in this RFC (x86, ARM, AArch64, RISC-V, Hexagon) all use the assembly code syntax of the GNU assembler (GAS). On x86, the `.intel_syntax noprefix` mode of GAS is used by default. On ARM, the `.syntax unified` mode is used. These targets impose an additional restriction on the assembly code: any assembler state (e.g. the current section which can be changed with `.section`) must be restored to its original value at the end of the asm string. Assembly code that does not conform to the GAS syntax will result in assembler-specific behavior.\n\n[rfc-2795]: https://github.com/rust-lang/rfcs/pull/2795\n\n## Operand type\n\nSeveral types of operands are supported:\n\n* `in() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain the value of `` at the start of the asm code.\n - The allocated register must contain the same value at the end of the asm code (except if a `lateout` is allocated to the same register).\n* `out() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain an undefined value at the start of the asm code.\n - `` must be a (possibly uninitialized) place expression, to which the contents of the allocated register is written to at the end of the asm code.\n - An underscore (`_`) may be specified instead of an expression, which will cause the contents of the register to be discarded at the end of the asm code (effectively acting as a clobber).\n* `lateout() `\n - Identical to `out` except that the register allocator can reuse a register allocated to an `in`.\n - You should only write to the register after all inputs are read, otherwise you may clobber an input.\n* `inout() `\n - `` can refer to a register class or an explicit register. The allocated register name is substituted into the asm template string.\n - The allocated register will contain the value of `` at the start of the asm code.\n - `` must be a mutable initialized place expression, to which the contents of the allocated register is written to at the end of the asm code.\n* `inout() => `\n - Same as `inout` except that the initial value of the register is taken from the value of ``.\n - `` must be a (possibly uninitialized) place expression, to which the contents of the allocated register is written to at the end of the asm code.\n - An underscore (`_`) may be specified instead of an expression for ``, which will cause the contents of the register to be discarded at the end of the asm code (effectively acting as a clobber).\n - `` and `` may have different types.\n* `inlateout() ` / `inlateout() => `\n - Identical to `inout` except that the register allocator can reuse a register allocated to an `in` (this can happen if the compiler knows the `in` has the same initial value as the `inlateout`).\n - You should only write to the register after all inputs are read, otherwise you may clobber an input.\n* `const `\n - `` must be an integer or floating-point constant expression.\n - The value of the expression is formatted as a string and substituted directly into the asm template string.\n* `sym `\n - `` must refer to a `fn` or `static`.\n - A mangled symbol name referring to the item is substituted into the asm template string.\n - The substituted string does not include any modifiers (e.g. GOT, PLT, relocations, etc).\n - `` is allowed to point to a `#[thread_local]` static, in which case the asm code can combine the symbol with relocations (e.g. `@plt`, `@TPOFF`) to read from thread-local data.\n\nOperand expressions are evaluated from left to right, just like function call arguments. After the `asm!` has executed, outputs are written to in left to right order. This is significant if two outputs point to the same place: that place will contain the value of the rightmost output.\n\n## Register operands\n\nInput and output operands can be specified either as an explicit register or as a register class from which the register allocator can select a register. Explicit registers are specified as string literals (e.g. `\"eax\"`) while register classes are specified as identifiers (e.g. `reg`). Using string literals for register names enables support for architectures that use special characters in register names, such as MIPS (`$0`, `$1`, etc).\n\nNote that explicit registers treat register aliases (e.g. `r14` vs `lr` on ARM) and smaller views of a register (e.g. `eax` vs `rax`) as equivalent to the base register. It is a compile-time error to use the same explicit register for two input operands or two output operands. Additionally, it is also a compile-time error to use overlapping registers (e.g. ARM VFP) in input operands or in output operands.\n\nOnly the following types are allowed as operands for inline assembly:\n- Integers (signed and unsigned)\n- Floating-point numbers\n- Pointers (thin only)\n- Function pointers\n- SIMD vectors (structs defined with `#[repr(simd)]` and which implement `Copy`). This includes architecture-specific vector types defined in `std::arch` such as `__m128` (x86) or `int8x16_t` (ARM).\n\nHere is the list of currently supported register classes:\n\n| Architecture | Register class | Registers | LLVM constraint code |\n| ------------ | -------------- | --------- | -------------------- |\n| x86 | `reg` | `ax`, `bx`, `cx`, `dx`, `si`, `di`, `r[8-15]` (x86-64 only) | `r` |\n| x86 | `reg_abcd` | `ax`, `bx`, `cx`, `dx` | `Q` |\n| x86-32 | `reg_byte` | `al`, `bl`, `cl`, `dl`, `ah`, `bh`, `ch`, `dh` | `q` |\n| x86-64 | `reg_byte` | `al`, `bl`, `cl`, `dl`, `sil`, `dil`, `r[8-15]b`, `ah`\\*, `bh`\\*, `ch`\\*, `dh`\\* | `q` |\n| x86 | `xmm_reg` | `xmm[0-7]` (x86) `xmm[0-15]` (x86-64) | `x` |\n| x86 | `ymm_reg` | `ymm[0-7]` (x86) `ymm[0-15]` (x86-64) | `x` |\n| x86 | `zmm_reg` | `zmm[0-7]` (x86) `zmm[0-31]` (x86-64) | `v` |\n| x86 | `kreg` | `k[1-7]` | `Yk` |\n| AArch64 | `reg` | `x[0-28]`, `x30` | `r` |\n| AArch64 | `vreg` | `v[0-31]` | `w` |\n| AArch64 | `vreg_low16` | `v[0-15]` | `x` |\n| ARM | `reg` | `r[0-5]` `r7`\\*, `r[8-10]`, `r11`\\*, `r12`, `r14` | `r` |\n| ARM (Thumb) | `reg_thumb` | `r[0-r7]` | `l` |\n| ARM (ARM) | `reg_thumb` | `r[0-r10]`, `r12`, `r14` | `l` |\n| ARM | `sreg` | `s[0-31]` | `t` |\n| ARM | `sreg_low16` | `s[0-15]` | `x` |\n| ARM | `dreg` | `d[0-31]` | `w` |\n| ARM | `dreg_low16` | `d[0-15]` | `t` |\n| ARM | `dreg_low8` | `d[0-8]` | `x` |\n| ARM | `qreg` | `q[0-15]` | `w` |\n| ARM | `qreg_low8` | `q[0-7]` | `t` |\n| ARM | `qreg_low4` | `q[0-3]` | `x` |\n| NVPTX | `reg16` | None\\* | `h` |\n| NVPTX | `reg32` | None\\* | `r` |\n| NVPTX | `reg64` | None\\* | `l` |\n| RISC-V | `reg` | `x1`, `x[5-7]`, `x[9-15]`, `x[16-31]` (non-RV32E) | `r` |\n| RISC-V | `freg` | `f[0-31]` | `f` |\n| Hexagon | `reg` | `r[0-28]` | `r` |\n\n> **Note**: On x86 we treat `reg_byte` differently from `reg` because the compiler can allocate `al` and `ah` separately whereas `reg` reserves the whole register.\n>\n> Note #2: On x86-64 the high byte registers (e.g. `ah`) are only available when used as an explicit register. Specifying the `reg_byte` register class for an operand will always allocate a low byte register.\n>\n> Note #3: NVPTX doesn't have a fixed register set, so named registers are not supported.\n>\n> Note #4: On ARM the frame pointer is either `r7` or `r11` depending on the platform.\n\nAdditional register classes may be added in the future based on demand (e.g. MMX, x87, etc).\n\nEach register class has constraints on which value types they can be used with. This is necessary because the way a value is loaded into a register depends on its type. For example, on big-endian systems, loading a `i32x4` and a `i8x16` into a SIMD register may result in different register contents even if the byte-wise memory representation of both values is identical. The availability of supported types for a particular register class may depend on what target features are currently enabled.\n\n| Architecture | Register class | Target feature | Allowed types |\n| ------------ | -------------- | -------------- | ------------- |\n| x86-32 | `reg` | None | `i16`, `i32`, `f32` |\n| x86-64 | `reg` | None | `i16`, `i32`, `f32`, `i64`, `f64` |\n| x86 | `reg_byte` | None | `i8` |\n| x86 | `xmm_reg` | `sse` | `i32`, `f32`, `i64`, `f64`,

The only exception is the `freg` register class on RISC-V where `f32` values are NaN-boxed in a `f64` as required by the RISC-V architecture.\n\nWhen separate input and output expressions are specified for an `inout` operand, both expressions must have the same type. The only exception is if both operands are pointers or integers, in which case they are only required to have the same size. This restriction exists because the register allocators in LLVM and GCC sometimes cannot handle tied operands with different types.\n\n## Register names\n\nSome registers have multiple names.

The frame pointer cannot be used as an input or output. |\n| ARM | `r6` | `r6` is used internally by LLVM as a base pointer and therefore cannot be used as an input or output. |\n| x86 | `k0` | This is a constant zero register which can't be modified. |\n| x86 | `ip` | This is the program counter, not a real register. |\n| x86 | `mm[0-7]` | MMX registers are not currently supported (but may be in the future). |\n| x86 | `st([0-7])` | x87 registers are not currently supported (but may be in the future). |\n| AArch64 | `xzr` | This is a constant zero register which can't be modified. |\n| ARM | `pc` | This is the program counter, not a real register. |\n| RISC-V | `x0` | This is a constant zero register which can't be modified. |\n| RISC-V | `gp`, `tp` | These registers are reserved and cannot be used as inputs or outputs. |\n| Hexagon | `lr` | This is the link register which cannot be used as an input or output. |\n\nIn some cases LLVM will allocate a \"reserved register\" for `reg` operands even though this register cannot be explicitly specified. Assembly code making use of reserved registers should be careful since `reg` operands may alias with those registers. Reserved registers are:\n- The frame pointer on all architectures.\n- `r6` on ARM.\n\n## Template modifiers\n\nThe placeholders can be augmented by modifiers which are specified after the `:` in the curly braces. These modifiers do not affect register allocation, but change the way operands are formatted when inserted into the template string. Only one modifier is allowed per template placeholder.\n\nThe supported modifiers are a subset of LLVM's (and GCC's) [asm template argument modifiers][llvm-argmod], but do not use the same letter codes.\n\n| Architecture | Register class | Modifier | Example output | LLVM modifier |\n| ------------ | -------------- | -------- | -------------- | ------------- |\n| x86-32 | `reg` | None | `eax` | `k` |\n| x86-64 | `reg` | None | `rax` | `q` |\n| x86-32 | `reg_abcd` | `l` | `al` | `b` |\n| x86-64 | `reg` | `l` | `al` | `b` |\n| x86 | `reg_abcd` | `h` | `ah` | `h` |\n| x86 | `reg` | `x` | `ax` | `w` |\n| x86 | `reg` | `e` | `eax` | `k` |\n| x86-64 | `reg` | `r` | `rax` | `q` |\n| x86 | `reg_byte` | None | `al` / `ah` | None |\n| x86 | `xmm_reg` | None | `xmm0` | `x` |\n| x86 | `ymm_reg` | None | `ymm0` | `t` |\n| x86 | `zmm_reg` | None | `zmm0` | `g` |\n| x86 | `*mm_reg` | `x` | `xmm0` | `x` |\n| x86 | `*mm_reg` | `y` | `ymm0` | `t` |\n| x86 | `*mm_reg` | `z` | `zmm0` | `g` |\n| x86 | `kreg` | None | `k1` | None |\n| AArch64 | `reg` | None | `x0` | `x` |\n| AArch64 | `reg` | `w` | `w0` | `w` |\n| AArch64 | `reg` | `x` | `x0` | `x` |\n| AArch64 | `vreg` | None | `v0` | None |\n| AArch64 | `vreg` | `v` | `v0` | None |\n| AArch64 | `vreg` | `b` | `b0` | `b` |\n| AArch64 | `vreg` | `h` | `h0` | `h` |\n| AArch64 | `vreg` | `s` | `s0` | `s` |\n| AArch64 | `vreg` | `d` | `d0` | `d` |\n| AArch64 | `vreg` | `q` | `q0` | `q` |\n| ARM | `reg` | None | `r0` | None |\n| ARM | `sreg` | None | `s0` | None |\n| ARM | `dreg` | None | `d0` | `P` |\n| ARM | `qreg` | None | `q0` | `q` |\n| ARM | `qreg` | `e` / `f` | `d0` / `d1` | `e` / `f` |\n| NVPTX | `reg16` | None | `rs0` | None |\n| NVPTX | `reg32` | None | `r0` | None |\n| NVPTX | `reg64` | None | `rd0` | None |\n| RISC-V | `reg` | None | `x1` | None |\n| RISC-V | `freg` | None | `f0` | None |\n| Hexagon | `reg` | None | `r0` | None |\n\n> Notes:\n> - on ARM `e` / `f`: this prints the low or high doubleword register name of a NEON quad (128-bit) register.\n> - on x86: our behavior for `reg` with no modifiers differs from what GCC does. GCC will infer the modifier based on the operand value type, while we default to the full register size.\n> - on x86 `xmm_reg`: the `x`, `t` and `g` LLVM modifiers are not yet implemented in LLVM (they are supported by GCC only), but this should be a simple change.\n\nAs stated in the previous section, passing an input value smaller than the register width will result in the upper bits of the register containing undefined values. This is not a problem if the inline asm only accesses the lower bits of the register, which can be done by using a template modifier to use a subregister name in the asm code (e.g. `ax` instead of `rax`). Since this an easy pitfall, the compiler will suggest a template modifier to use where appropriate given the input type. If all references to an operand already have modifiers then the warning is suppressed for that operand.\n\n[llvm-argmod]: http://llvm.org/docs/LangRef.html#asm-template-argument-modifiers\n\n## Options\n\nFlags are used to further influence the behavior of the inline assembly block.\nCurrently the following options are defined:\n- `pure`: The `asm` block has no side effects, and its outputs depend only on its direct inputs (i.e. the values themselves, not what they point to) or values read from memory (unless the `nomem` options is also set). This allows the compiler to execute the `asm` block fewer times than specified in the program (e.g. by hoisting it out of a loop) or even eliminate it entirely if the outputs are not used.\n- `nomem`: The `asm` blocks does not read or write to any memory. This allows the compiler to cache the values of modified global variables in registers across the `asm` block since it knows that they are not read or written to by the `asm`.\n- `readonly`: The `asm` block does not write to any memory. This allows the compiler to cache the values of unmodified global variables in registers across the `asm` block since it knows that they are not written to by the `asm`.\n- `preserves_flags`: The `asm` block does not modify the flags register (defined in the rules below). This allows the compiler to avoid recomputing the condition flags after the `asm` block.\n- `noreturn`: The `asm` block never returns, and its return type is defined as `!` (never). Behavior is undefined if execution falls through past the end of the asm code. A `noreturn` asm block behaves just like a function which doesn't return; notably, local variables in scope are not dropped before it is invoked.\n- `nostack`: The `asm` block does not push data to the stack, or write to the stack red-zone (if supported by the target). If this option is *not* used then the stack pointer is guaranteed to be suitably aligned (according to the target ABI) for a function call.\n- `att_syntax`: This option is only valid on x86, and causes the assembler to use the `.att_syntax prefix` mode of the GNU assembler. Register operands are substituted in with a leading `%`.\n\nThe compiler performs some additional checks on options:\n- The `nomem` and `readonly` options are mutually exclusive: it is a compile-time error to specify both.\n- The `pure` option must be combined with either the `nomem` or `readonly` options, otherwise a compile-time error is emitted.\n- It is a compile-time error to specify `pure` on an asm block with no outputs or only discarded outputs (`_`).\n- It is a compile-time error to specify `noreturn` on an asm block with outputs.\n\n## Rules for inline assembly\n\n- Any registers not specified as inputs will contain an undefined value on entry to the asm block.\n - An \"undefined value\" in the context of inline assembly means that the register can (non-deterministically) have any one of the possible values allowed by the architecture. Notably it is not the same as an LLVM `undef` which can have a different value every time you read it (since such a concept does not exist in assembly code).\n- Any registers not specified as outputs must have the same value upon exiting the asm block as they had on entry, otherwise behavior is undefined.\n - This only applies to registers which can be specified as an input or output. Other registers follow target-specific rules.\n - Note that a `lateout` may be allocated to the same register as an `in`, in which case this rule does not apply. Code should not rely on this however since it depends on the results of register allocation.\n- Behavior is undefined if execution unwinds out of an asm block.\n - This also applies if the assembly code calls a function which then unwinds.\n- The set of memory locations that assembly code is allowed the read and write are the same as those allowed for an FFI function.\n - Refer to the unsafe code guidelines for the exact rules.\n - If the `readonly` option is set, then only memory reads are allowed.\n - If the `nomem` option is set then no reads or writes to memory are allowed.\n - These rules do not apply to memory which is private to the asm code, such as stack space allocated within the asm block.\n- The compiler cannot assume that the instructions in the asm are the ones that will actually end up executed.\n - This effectively means that the compiler must treat the `asm!` as a black box and only take the interface specification into account, not the instructions themselves.\n - Runtime code patching is allowed, via target-specific mechanisms (outside the scope of this RFC).\n- Unless the `nostack` option is set, asm code is allowed to use stack space below the stack pointer.\n - On entry to the asm block the stack pointer is guaranteed to be suitably aligned (according to the target ABI) for a function call.\n - You are responsible for making sure you don't overflow the stack (e.g. use stack probing to ensure you hit a guard page).\n - You should adjust the stack pointer when allocating stack memory as required by the target ABI.\n - The stack pointer must be restored to its original value before leaving the asm block.\n- If the `noreturn` option is set then behavior is undefined if execution falls through to the end of the asm block.\n- If the `pure` option is set then behavior is undefined if the `asm` has side-effects other than its direct outputs. Behavior is also undefined if two executions of the `asm` code with the same inputs result in different outputs.\n - When used with the `nomem` option, \"inputs\" are just the direct inputs of the `asm!`.\n - When used with the `readonly` option, \"inputs\" comprise the direct inputs of the `asm!` and any memory that the `asm!` block is allowed to read.\n- These flags registers must be restored upon exiting the asm block if the `preserves_flags` option is set:\n - x86\n - Status flags in `EFLAGS` (CF, PF, AF, ZF, SF, OF).\n - Floating-point status word (all).\n - Floating-point exception flags in `MXCSR` (PE, UE, OE, ZE, DE, IE).\n - ARM\n - Condition flags in `CPSR` (N, Z, C, V)\n - Saturation flag in `CPSR` (Q)\n - Greater than or equal flags in `CPSR` (GE).\n - Condition flags in `FPSCR` (N, Z, C, V)\n - Saturation flag in `FPSCR` (QC)\n - Floating-point exception flags in `FPSCR` (IDC, IXC, UFC, OFC, DZC, IOC).\n - AArch64\n - Condition flags (`NZCV` register).\n - Floating-point status (`FPSR` register).\n - RISC-V\n - Floating-point exception flags in `fcsr` (`fflags`).\n- On x86, the direction flag (DF in `EFLAGS`) is clear on entry to an asm block and must be clear on exit.\n - Behavior is undefined if the direction flag is set on exiting an asm block.\n- The requirement of restoring the stack pointer and non-output registers to their original value only applies when exiting an `asm!` block.\n - This means that `asm!` blocks that never return (even if not marked `noreturn`) don't need to preserve these registers.\n - When returning to a different `asm!` block than you entered (e.g. for context switching), these registers must contain the value they had upon entering the `asm!` block that you are *exiting*.\n - You cannot exit an `asm!` block that has not been entered. Neither can you exit an `asm!` block that has already been exited.\n - You are responsible for switching any target-specific state (e.g. thread-local storage, stack bounds).\n - The set of memory locations that you may access is the intersection of those allowed by the `asm!` blocks you entered and exited.\n- You cannot assume that an `asm!` block will appear exactly once in the output binary. The compiler is allowed to instantiate multiple copies of the `asm!` block, for example when the function containing it is inlined in multiple places.\n - As a consequence, you should only use [local labels] inside inline assembly code. Defining symbols in assembly code may lead to assembler and/or linker errors due to duplicate symbol definitions.\n\n> **Note**: As a general rule, the flags covered by `preserves_flags` are those which are *not* preserved when performing a function call.\n\n[local labels]: https://sourceware.org/binutils/docs/as/Symbol-Names.html#Local-Labels\n" } , LintCompletion { label : "is_sorted" ,

This is useful for very low level programming, where\nwhich register you use is important:\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# unsafe fn read_byte_in(port: u16) -> u8 {\nlet result: u8;\nllvm_asm!(\"in %dx, %al\" : \"={al}\"(result) : \"{dx}\"(port));\nresult\n# }\n```\n\n## Clobbers\n\nSome instructions modify registers which might otherwise have held\ndifferent values so we use the clobbers list to indicate to the\ncompiler not to assume any values loaded into those registers will\nstay valid.\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# fn main() { unsafe {\n// Put the value 0x200 in eax:\nllvm_asm!(\"mov $$0x200, %eax\" : /* no outputs */ : /* no inputs */ : \"eax\");\n# } }\n# #[cfg(not(any(target_arch = \"x86\", target_arch = \"x86_64\")))]\n# fn main() {}\n```\n\nInput and output registers need not be listed since that information\nis already communicated by the given constraints. Otherwise, any other\nregisters used either implicitly or explicitly should be listed.\n\nIf the assembly changes the condition code register `cc` should be\nspecified as one of the clobbers. Similarly, if the assembly modifies\nmemory, `memory` should also be specified.\n\n## Options\n\nThe last section, `options` is specific to Rust. The format is comma\nseparated literal strings (i.e. `:\"foo\", \"bar\", \"baz\"`). It's used to\nspecify some extra info about the inline assembly:\n\nCurrent valid options are:\n\n1. *volatile* - specifying this is analogous to\n `__asm__ __volatile__ (...)` in gcc/clang.\n2. *alignstack* - certain instructions expect the stack to be\n aligned a certain way (i.e. SSE) and specifying this indicates to\n the compiler to insert its usual stack alignment code\n3. *intel* - use intel syntax instead of the default AT&T.\n\n```rust\n# #![feature(llvm_asm)]\n# #[cfg(any(target_arch = \"x86\", target_arch = \"x86_64\"))]\n# fn main() {\nlet result: i32;\nunsafe {\n llvm_asm!(\"mov eax, 2\" : \"={eax}\"(result) : : : \"intel\")\n}\nprintln!(\"eax is currently {}\", result);\n# }\n# #[cfg(not(any(target_arch = \"x86\", target_arch = \"x86_64\")))]\n# fn main() {}\n```\n\n## More Information\n\nThe current implementation of the `llvm_asm!` macro is a direct binding to [LLVM's\ninline assembler expressions][llvm-docs], so be sure to check out [their\ndocumentation as well][llvm-docs] for more information about clobbers,\nconstraints, etc.\n\n[llvm-docs]: http://llvm.org/docs/LangRef.html#inline-assembler-expressions\n\nIf you need more power and don't mind losing some of the niceties of\n`llvm_asm!`, check out [global_asm](global-asm.md).\n" } ] ; diff --git a/xtask/src/codegen.rs b/xtask/src/codegen.rs index c7cac50fe8..1edb04c2f1 100644 --- a/xtask/src/codegen.rs +++ b/xtask/src/codegen.rs @@ -42,6 +42,7 @@ const ASSISTS_TESTS: &str = "crates/ra_assists/src/tests/generated.rs"; const REPOSITORY_URL: &str = "https://github.com/rust-lang/rust"; const UNSTABLE_FEATURE: &str = "crates/ra_ide/src/completion/unstable_feature_descriptor.rs"; +const REPO_PATH: &str = "src/doc/unstable-book/src"; #[derive(Debug, PartialEq, Eq, Clone, Copy)] pub enum Mode { diff --git a/xtask/src/codegen/gen_unstable_future_descriptor.rs b/xtask/src/codegen/gen_unstable_future_descriptor.rs index 56065f17da..3f3beb5914 100644 --- a/xtask/src/codegen/gen_unstable_future_descriptor.rs +++ b/xtask/src/codegen/gen_unstable_future_descriptor.rs @@ -2,27 +2,13 @@ use crate::codegen::update; use crate::codegen::{self, project_root, Mode, Result}; +use crate::not_bash::{fs2, pushd, run}; +use proc_macro2::TokenStream; use quote::quote; -use std::fs; -use std::process::Command; +use std::path::PathBuf; use walkdir::WalkDir; -pub fn generate_unstable_future_descriptor(mode: Mode) -> Result<()> { - let path = project_root().join(codegen::STORAGE); - fs::create_dir_all(path.clone())?; - - Command::new("git").current_dir(path.clone()).arg("init").output()?; - Command::new("git") - .current_dir(path.clone()) - .args(&["remote", "add", "-f", "origin", codegen::REPOSITORY_URL]) - .output()?; - Command::new("git") - .current_dir(path.clone()) - .args(&["sparse-checkout", "set", "/src/doc/unstable-book/src/"]) - .output()?; - Command::new("git").current_dir(path.clone()).args(&["pull", "origin", "master"]).output()?; - - let src_dir = path.join("src/doc/unstable-book/src"); +fn generate_descriptor(src_dir: PathBuf) -> Result { let files = WalkDir::new(src_dir.join("language-features")) .into_iter() .chain(WalkDir::new(src_dir.join("library-features"))) @@ -49,13 +35,27 @@ pub fn generate_unstable_future_descriptor(mode: Mode) -> Result<()> { let ts = quote! { use crate::completion::LintCompletion; - pub const UNSTABLE_FEATURE_DESCRIPTOR: &[LintCompletion] = &[ + pub(crate) const UNSTABLE_FEATURE_DESCRIPTOR: &[LintCompletion] = &[ #(#definitions),* ]; }; + Ok(ts) +} +pub fn generate_unstable_future_descriptor(mode: Mode) -> Result<()> { + let path = project_root().join(codegen::STORAGE); + fs2::create_dir_all(path.clone())?; + + let _d = pushd(path.clone()); + run!("git init")?; + run!("git remote add -f origin {}", codegen::REPOSITORY_URL)?; + run!("git pull origin master")?; + + let src_dir = path.join(codegen::REPO_PATH); + let content = generate_descriptor(src_dir)?.to_string(); + + let contents = crate::reformat(content)?; let destination = project_root().join(codegen::UNSTABLE_FEATURE); - let contents = crate::reformat(ts.to_string())?; update(destination.as_path(), &contents, mode)?; Ok(()) From 73315c9168901ef6d676f017daaa9b4976380c03 Mon Sep 17 00:00:00 2001 From: Dmitry Date: Sat, 15 Aug 2020 01:43:34 +0700 Subject: [PATCH 18/20] synchronizing changes --- crates/hir/src/has_source.rs | 2 +- crates/ide/src/completion.rs | 6 +++++ .../ide/src/completion/complete_attribute.rs | 23 +++++++++++++------ .../completion/unstable_feature_descriptor.rs | 0 xtask/src/codegen.rs | 8 +++---- .../codegen/gen_unstable_future_descriptor.rs | 3 +-- 6 files changed, 28 insertions(+), 14 deletions(-) rename crates/{ra_ide => ide}/src/completion/unstable_feature_descriptor.rs (100%) diff --git a/crates/hir/src/has_source.rs b/crates/hir/src/has_source.rs index a50d4ff029..3bad2338a2 100644 --- a/crates/hir/src/has_source.rs +++ b/crates/hir/src/has_source.rs @@ -1,4 +1,4 @@ -//!
