FP fix and documentation for `branches_sharing_code` lint

Closes rust-lang/rust-clippy#7369

Related rust-lang/rust-clippy#7452 I'm still thinking about the best way to fix this. I could simply add another visitor to ensure that the moved expressions don't modify values being used in the condition, but I'm not totally happy with this due to the complexity. I therefore only documented it for now

Don't suggest doc(hidden) or unstable variants in wildcard lint

Clippy's wildcard lint would suggest doc(hidden) and unstable variants for non_exhaustive enums, even though those aren't part of the public interface (yet) and should only be matched on using a `_`, just like potential future additions to the enum. There was already some logic to exclude a *single* doc(hidden) variant. This extends that to all hidden variants, and also hides `#[unstable]` variants.

See https://github.com/rust-lang/rust/pull/85746#issuecomment-868886893

This PR includes https://github.com/rust-lang/rust-clippy/pull/7406 as the first commit.

Here's the diff that this PR adds on top of that PR: https://github.com/m-ou-se/rust-clippy/compare/std-errorkind...m-ou-se:doc-hidden-variants

This fixes a bug where match_wildcard_for_single_variants produced a
bad suggestion where besides the missing variant, one or more hidden
variants were left.

This also adds tests to the ui-tests match_wildcard_for_single_variants
and wildcard_enum_match_arm to make sure that the correct suggestion is
produced.

New lint: `disallowed_script_idents`

This PR implements a new lint to restrict locales that can be used in the code,
as proposed in #7376.

Current concerns / unresolved questions:

- ~~Mixed usage of `script` (as a Unicode term) and `locale` (as something that is easier to understand for the broad audience). I'm not sure whether these terms are fully interchangeable and whether in the current form it is more confusing than helpful.~~ `script` is now used everywhere.
- ~~Having to mostly copy-paste `AllowedScript`. Probably it's not a big problem, as the list of scripts is standardized and is unlikely to change, and even if we'd stick to the `unicode_script::Script`, we'll still have to implement custom deserialization, and I don't think that it will be shorter in terms of the amount of LoC.~~ `unicode::Script` is used together with a filtering deserialize function.
- Should we stick to the list of "recommended scripts" from [UAX #31](http://www.unicode.org/reports/tr31/#Table_Recommended_Scripts) in the configuration?

Fixed broken deploy script due to multiline configuration docs

The deploy script on master currently runs into an error (See [log](https://github.com/rust-lang/rust-clippy/runs/2865828873)) due to the new configuration documentation added in #7299. The current documentation collection for the configuration macro sadly doesn't support multiline doc comments. This will be changes in the future with the new metadata collector tracked in #7172 For now we have to use `<br>` inside doc comments to add paragraphs.

This PR restricts `define_Conf!` macro to single lines and adds a comment explaining the reasoning behind it. It also adjusted the actual document parsing to fix a bug. (The parsing was automatically stopping on the first curly bracket, even if it was part of a doc comment).

Remove requirement of fully qualified path for disallowed_method/type

changelog: Remove the need for fully qualified paths in disallowed_method and disallowed_type

After fixing this issue in [import_rename](https://github.com/rust-lang/rust-clippy/pull/7300#discussion_r650127720) I figured I'd fix it for these two.

If this does in fact fix the **Known problems:** section I was planning to remove them from both lints after confirmation.

Don't trigger `field_reassign_with_default` in macros

Fixes #7155

Producing a good suggestion for this lint is already hard when no macros
are involved. With macros the lint message and the suggestion are just
confusing. Since both, producing a good suggestion and figuring out if
this pattern can be re-written inside a macro is nearly impossible, just
bail out.

changelog: [`field_reassign_with_default`] No longer triggers in macros

Fix false positive on `semicolon_if_nothing_returned`

Currently the [`semicolon_if_nothing_returned`](https://rust-lang.github.io/rust-clippy/master/index.html#semicolon_if_nothing_returned) lint fires in unwanted situations where a block only spans one line. An example of this was given in #7324. This code:

```rust
use std::mem::MaybeUninit;
use std::ptr;

fn main() {
    let mut s = MaybeUninit::<String>::uninit();
    let _d = || unsafe { ptr::drop_in_place(s.as_mut_ptr()) };
}
```

yields the following clippy error:
```
error: consider adding a `;` to the last statement for consistent formatting
 --> src/main.rs:6:26
  |
6 |     let _d = || unsafe { ptr::drop_in_place(s.as_mut_ptr()) };
  |                          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: add a `;` here: `ptr::drop_in_place(s.as_mut_ptr());`
  |
  = note: `-D clippy::semicolon-if-nothing-returned` implied by `-D clippy::pedantic`
  = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#semicolon_if_nothing_returned
```

I updated the lint to check if the statement is inside an `unsafe` block, a closure or a normal block and if the block only spans one line, in that case the lint is not emitted.

This closes #7324.

changelog: enhanced semicolon if nothing returned according to  #7324.

Refactoring identity function lints

I've noticed that we have several lints that all check for identity functions and each used their own check implementation. I moved the `is_expr_identity_function` function to `clippy_utils` and adapted all lints to reuse that one function. This should make the addition of new lints like this also easier in the future.

I've also moved the `map_identity` lint into the `methods` module. It's probably the best to review this PR by checking each commit individually. And that's it, have a great day 🙃

changelog: Deprecates [`pub_enum_variant_names`] and [`wrong_pub_self_convention`] as the non-pub variants are now configurable.

changelog: Fix various false negatives for `pub` items that are not exported from the crate.

A couple changes to late passes in order to use `cx.access_levels.is_exported` rather than `item.vis.kind.is_pub`.

I'm not sure how to better document the config option or lints that are (not) affected (see comments in #6806). Suggestions are welcome. cc `@rust-lang/clippy`

I added `/clippy.toml` to use the config internally and `/tests/clippy.toml` to maintain a default config in ui tests.

fixes #1594

changelog: Add ``[`needless_bitwise_bool`]`` lint

Creates a new `bitwise_bool` lint to convert `x & y` to `x && y` when both `x` and `y` are booleans. I also had to adjust thh `needless_bool` lint slightly, and fix a couple failing dogfood tests. I made it a correctness lint as per flip1995's comment [here](https://github.com/rust-lang/rust-clippy/pull/3385#issuecomment-434715723), from a previous WIP attempt at this lint.

New lint: `unused_async`

changelog: Adds a lint, `unused_async`, which checks for async functions with no await statements

`unused_async` is a lint that reduces code smell and overhead by encouraging async functions to be refactored into synchronous functions.

Fixes #7176

### Examples

```rust
async fn get_random_number() -> i64 {
    4 // Chosen by fair dice roll. Guaranteed to be random.
}
```

Could be written as:

```rust
fn get_random_number() -> i64 {
    4 // Chosen by fair dice roll. Guaranteed to be random.
}
```

Something like this, however, should **not** be caught by clippy:
```rust
#[async_trait]
trait AsyncTrait {
    async fn foo();
}

struct Bar;

#[async_trait]
impl AsyncTrait for Bar {
    async fn foo() {
        println!("bar");
    }
}

Metadata collection monster searching for Clippy's configuration options

This PR teaches our lovely metadata collection monster which configurations are available inside Clippy. It then adds a new *Configuration* section to the lint documentation.

---

The implementation uses the `define_Conf!` macro to create a vector of metadata during compilation. This enables easy collection and parsing without the need of searching for the struct during a lint-pass (and it's quite elegant IMO). The information is then parsed into an intermediate struct called `ClippyConfiguration` which will be saved inside the `MetadataCollector` struct itself. It is currently only used to generate the *Configuration* section in the lint documentation, but I'm thinking about adding an overview of available configurations to the website. Saving them in this intermediate state without formatting them right away enables this in the future.

The new parsing will also allow us to have a documentation that spans over multiple lines in the future. For example, this will be valid when the old script has been removed:
```rust
/// Lint: BLACKLISTED_NAME.
/// The list of blacklisted names to lint about. NB: `bar` is not here since it has legitimate uses
(blacklisted_names: Vec<String> = ["foo", "baz", "quux"].iter().map(ToString::to_string).collect())
```

The deprecation reason is also currently being collected but not used any further and that's basically it.

Fix `--remap-path-prefix` not correctly remapping `rust-src` component paths and unify handling of path mapping with virtualized paths

This PR fixes #73167 ("Binaries end up containing path to the rust-src component despite `--remap-path-prefix`") by preventing real local filesystem paths from reaching compilation output if the path is supposed to be remapped.

`RealFileName::Named` introduced in #72767 is now renamed as `LocalPath`, because this variant wraps a (most likely) valid local filesystem path.

`RealFileName::Devirtualized` is renamed as `Remapped` to be used for remapped path from a real path via `--remap-path-prefix` argument, as well as real path inferred from a virtualized (during compiler bootstrapping) `/rustc/...` path. The `local_path` field is now an `Option<PathBuf>`, as it will be set to `None` before serialisation, so it never reaches any build output. Attempting to serialise a non-`None` `local_path` will cause an assertion faliure.

When a path is remapped, a `RealFileName::Remapped` variant is created. The original path is preserved in `local_path` field and the remapped path is saved in `virtual_name` field. Previously, the `local_path` is directly modified which goes against its purpose of "suitable for reading from the file system on the local host".

`rustc_span::SourceFile`'s fields `unmapped_path` (introduced by #44940) and `name_was_remapped` (introduced by #41508 when `--remap-path-prefix` feature originally added) are removed, as these two pieces of information can be inferred from the `name` field: if it's anything other than a `FileName::Real(_)`, or if it is a `FileName::Real(RealFileName::LocalPath(_))`, then clearly `name_was_remapped` would've been false and `unmapped_path` would've been `None`. If it is a `FileName::Real(RealFileName::Remapped{local_path, virtual_name})`, then `name_was_remapped` would've been true and `unmapped_path` would've been `Some(local_path)`.

ab73020d40 Implement span quoting for proc-macros
This PR implements span quoting, allowing proc-macros to produce spans
pointing *into their own crate*. This is used by the unstable
`proc_macro::quote!` macro, allowing us to get error messages like this:

```
error[E0412]: cannot find type `MissingType` in this scope
  --> $DIR/auxiliary/span-from-proc-macro.rs:37:20
   |
LL | pub fn error_from_attribute(_args: TokenStream, _input: TokenStream) -> TokenStream {
   | ----------------------------------------------------------------------------------- in this expansion of procedural macro `#[error_from_attribute]`
...
LL |             field: MissingType
   |                    ^^^^^^^^^^^ not found in this scope
   |
  ::: $DIR/span-from-proc-macro.rs:8:1
   |
LL | #[error_from_attribute]
   | ----------------------- in this macro invocation
```

Here, `MissingType` occurs inside the implementation of the proc-macro
`#[error_from_attribute]`. Previosuly, this would always result in a
span pointing at `#[error_from_attribute]`

This will make many proc-macro-related error message much more useful -
when a proc-macro generates code containing an error, users will get an
error message pointing directly at that code (within the macro
definition), instead of always getting a span pointing at the macro
invocation site.

This is implemented as follows:
* When a proc-macro crate is being *compiled*, it causes the `quote!`
  macro to get run. This saves all of the sapns in the input to `quote!`
  into the metadata of *the proc-macro-crate* (which we are currently
  compiling). The `quote!` macro then expands to a call to
  `proc_macro::Span::recover_proc_macro_span(id)`, where `id` is an
opaque identifier for the span in the crate metadata.
* When the same proc-macro crate is *run* (e.g. it is loaded from disk
  and invoked by some consumer crate), the call to
`proc_macro::Span::recover_proc_macro_span` causes us to load the span
from the proc-macro crate's metadata. The proc-macro then produces a
`TokenStream` containing a `Span` pointing into the proc-macro crate
itself.

The recursive nature of 'quote!' can be difficult to understand at
first. The file `src/test/ui/proc-macro/quote-debug.stdout` shows
the output of the `quote!` macro, which should make this eaier to
understand.

This PR also supports custom quoting spans in custom quote macros (e.g.
the `quote` crate). All span quoting goes through the
`proc_macro::quote_span` method, which can be called by a custom quote
macro to perform span quoting. An example of this usage is provided in
`src/test/ui/proc-macro/auxiliary/custom-quote.rs`

Custom quoting currently has a few limitations:

In order to quote a span, we need to generate a call to
`proc_macro::Span::recover_proc_macro_span`. However, proc-macros
support renaming the `proc_macro` crate, so we can't simply hardcode
this path. Previously, the `quote_span` method used the path
`crate::Span` - however, this only works when it is called by the
builtin `quote!` macro in the same crate. To support being called from
arbitrary crates, we need access to the name of the `proc_macro` crate
to generate a path. This PR adds an additional argument to `quote_span`
to specify the name of the `proc_macro` crate. Howver, this feels kind
of hacky, and we may want to change this before stabilizing anything
quote-related.

Additionally, using `quote_span` currently requires enabling the
`proc_macro_internals` feature. The builtin `quote!` macro
has an `#[allow_internal_unstable]` attribute, but this won't work for
custom quote implementations. This will likely require some additional
tricks to apply `allow_internal_unstable` to the span of
`proc_macro::Span::recover_proc_macro_span`.

Don't trigger field_reassign_with_default in macros
Producing a good suggestion for this lint is already hard when no macros
are involved. With macros the lint message and the suggestion are just
confusing. Since both, producing a good suggestion and figuring out if
this pattern can be re-written inside a macro is nearly impossible, just
bail out.

Fix FN in `iter_cloned_collect` with a large array

fixes #6808
changelog: Fix FN in `iter_cloned_collect` with a large array

I spotted that [is_iterable_array](a362a4d1d0/clippy_lints/src/loops/explicit_iter_loop.rs (L67-L75)) function that `explicit_iter_loop` lint is using only works for array sizes <= 32.
There is this comment:
> IntoIterator is currently only implemented for array sizes <= 32 in rustc

I'm a bit confused, because I read that [IntoIterator for arrays](https://doc.rust-lang.org/src/core/array/mod.rs.html#194-201) with const generic `N` is stable since = "1.0.0". Although Const Generics MVP were stabilized in Rust 1.51.

Should I set MSRV for the current change? I will try to test with older compilers soon.

Fix: redundant_pattern_matching drop order

Fixes #5746

A note about the change in drop order is added when the scrutinee (or any temporary in the expression) isn't known to be safe to drop in any order (i.e. doesn't implement the `Drop` trait, or contain such a type). There is a whitelist for some `std` types, but it's incomplete. Currently just `Vec<_>`, `Box<_>`, `Rc<_>` and `Arc<_>`, but only if the contained type is also safe to drop in any order.

Another lint for when the drop order changes could be added as allowed by default, but the drop order requirement is pretty subtle in this case. I think the note added to the lint should be enough to make someone think before applying the change.

Don't allow adjustments for `manual_map`

fixes: #7077

The other option here would be to add the return type to the closure. It would be fine for simple types, but longer types can be rather unwieldy. Could also implement the adjustment manually.

changelog: Don't lint `manual_map` when type adjustments are added. e.g. autoderef

Remove `match_path` and `match_qpath`

The only remaining usage is the `author` lint, so the functions are left in for now. The test result for `repl_uninit` changed, the lint was broken before.

The `collapsible_span_lint_calls` and `match_type_on_diag_item` tests have been changed. Both lints were broken when utils was extracted into it's own crate. `match_type_on_diag_item` isn't quite fixed, but it's at least less broken.

tabs_in_doc_comments: Fix ICE due to char indexing

This is a quick-fix for an ICE in `tabs_in_doc_comments`. The problem
was that we we're indexing into possibly multi-byte characters, such as '位'.

More specifically `get_chunks_of_tabs` was returning indices into
multi-byte characters. Those were passed on to a `Span` creation that
then caused the ICE.

This fix makes sure that we don't return indices that point inside a
multi-byte character. *However*, we are still iterating over unicode
codepoints, not grapheme clusters. So a seemingly single character like y̆ ,
which actually consists of two codepoints, will probably still cause
incorrect spans in the output. But I don't think we handle those cases
anywhere in Clippy currently?

Fixes #5835

Fix a FP in `missing_const_for_fn`

where a function that calls a standard library function whose constness
is unstable is considered as being able to be a const function. Fixes #5995.

The core change is the move from `rustc_mir::const_eval::is_min_const_fn` to `rustc_mir::const_eval::is_const_fn`. I'm not clear about the difference in their purpose between them so I'm not sure if it's acceptable to call `qualify_min_const_fn::is_min_const_fn` this way now.

New Lint: `branches_sharing_code`

This lint checks if all `if`-blocks contain some statements that are the same and can be moved out of the blocks to prevent code duplication. Here is an example:

```rust
let _ = if ... {
    println!("Start"); // <-- Lint for code duplication
    let _a = 99;
    println!("End"); // <-- Lint for code duplication
    false
} else {
    println!("Start");
    let _b = 17;
    println!("End");
    false
};
```

This could be written as:

```rust
println!("Start");

let _ = if ... {
    let _a = 99;
    false
} else {
    let _b = 17;
    false
};

println!("End");
```

---

This lint will get masked by the `IF_SAME_THEN_ELSE` lint. I think it makes more sense to only emit one lint per if block. This means that the folloing example:

```rust
if ... {
    let _a = 17;
} else {
    let _a = 17;
}
```

Will only trigger the `IF_SAME_THEN_ELSE` lint and not the `SHARED_CODE_IN_IF_BLOCKS` lint.

Lint: filter(Option::is_some).map(Option::unwrap)

Fixes #6061

*Please write a short comment explaining your change (or "none" for internal only changes)*
changelog:
* add new lint for filter(Option::is_some).map(Option::unwrap)

First Rust PR, so I'm sure I've violated some idioms. Happy to change anything.

I'm getting one test failure locally -- a stderr diff for `compile_test`. I'm having a hard time seeing how I could be causing it, so I'm tentatively opening this in the hopes that it's an artifact of my local setup against `rustc`. Hoping it can at least still be reviewed in the meantime.

I'm gathering that since this is a method lint, and `.filter(...).map(...)` is already checked, the means of implementation needs to be a little different, so I didn't exactly follow the setup boilerplate. My way of checking for method calls seems a little too direct (ie, "is the second element of the expression literally the path for `Option::is_some`?"), but it seems like that's how some other lints work, so I went with it. I'm assuming we're not concerned about, eg, closures that just end up equivalent to `Option::is_some` by eta reduction.

disable upper_case_acronyms for pub items - enum edition

Fixes https://github.com/rust-lang/rust-clippy/issues/6803 (again... 😅  )

My previous fix did not work for enums because enum variants were checked separately in the `check_variant` function but it looks like we can't use that because we can't tell if the enum the variants belong to is declared as public or not (it always said `Inherited` for me)

I went and special-cased enums and iterated over all the variants "manually", but only, if the enums is not public.

a57a8c3058 Remove (lots of) dead code
Found with https://github.com/est31/warnalyzer.

Dubious changes:
- Is anyone else using rustc_apfloat? I feel weird completely deleting
  x87 support.
- Maybe some of the dead code in rustc_data_structures, in case someone
  wants to use it in the future?
- Don't change rustc_serialize

  I plan to scrap most of the json module in the near future (see
  https://github.com/rust-lang/compiler-team/issues/418) and fixing the
  tests needed more work than I expected.

TODO: check if any of the comments on the deleted code should be kept.

#5733 is only fixed in the normal case, if different paths are used for the variants then the same problem will occur. It's cause by `def_path_str` returning an utterly useless result. I haven't dug into why yet.

For #6604 there should be some discussion before accepting this. It's easy enough to change the message rather than disable the lint for `Option` and `Result`.

I've taken the liberty of updating the `since` values to 1.52, since an unobservable deprecation isn't much of a deprecation (even the detailed release notes never bothered to mention these deprecations).

As mentioned in the issue I'm *pretty* sure that using a type alias for `Bound` is semantically equivalent to the re-export; [the reference implies](https://doc.rust-lang.org/reference/items/type-aliases.html) that type aliases only observably differ from types when used on unit structs or tuple structs, whereas `Bound` is an enum.

ast/hir: Rename field-related structures

I always forget what `ast::Field` and `ast::StructField` mean despite working with AST for long time, so this PR changes the naming to less confusing and more consistent.

- `StructField` -> `FieldDef` ("field definition")
- `Field` -> `ExprField` ("expression field", not "field expression")
- `FieldPat` -> `PatField` ("pattern field", not "field pattern")

Various visiting and other methods working with the fields are renamed correspondingly too.

The second commit reduces the size of `ExprKind` by boxing fields of `ExprKind::Struct` in preparation for https://github.com/rust-lang/rust/pull/80080.

fixes #6758
changelog: wrong_self_convention: fix lint in case of `to_*_mut` method. When a method starts with `to_` and ends with `_mut`, clippy expects a `&mut self` parameter, otherwise `&self`.

Any feedback is welcome. I was also thinking if shouldn't we treat `to_` the same way as `as_`. Namely to accept `self` taken:  `&self` or `&mut self`.

Improve needless_borrowed_ref docs

changelog: none

I think "borrowed ref" is a confusing description for this lint. Destructuring a reference is the opposite of borrowing. So I updated the wording throughout the docs. Unfortunately this nit applies to the name of the lint itself, but I won't bother changing that. One motivation for these changes is to clarify the difference between this lint and `needless_borrow` (they are actually quite different). Let me know if I need to clarify anything or if you disagree with any changes.

Refactor casts lint

Ref: #6724

Changes:
1. Separate the `casts` group from the `types` group.
2. Reorganize the lints of the `casts` group into their own modules.

Notes:
1. I didn't `fix` #6874 in order to maintain this PR as small as possible.

or-patterns: disallow in `let` bindings

~~Blocked on https://github.com/rust-lang/rust/pull/81869~~

Disallows top-level or-patterns before type ascription. We want to reserve this syntactic space for possible future generalized type ascription.

Fix false positive for unit_arg lint

Fixes #6447

To avoid false positives don't complain about unit args when they come from a path expression, e.g. a local variable.

**Note:** This is my first contribution to Clippy, so I might have messed up somewhere. Any feedback is welcome and I'm happy to work out any kinks.

2f0e9f7d3a or_fun_call: fix suggestion for or_insert(vec![])
Applies for `std::collections::hash_map::Entry` and `std::collections::btree_map::Entry`

Example:
Previously, for the following code:
`let _ = hash_map.entry("test".to_owned()).or_insert(vec![]);`
clippy would suggest to use:
`or_insert_with(vec![])`, which causes a compiler error (E0277).

Now clippy suggests:
`or_insert_with(Vec::new)`

move upper_case_acronyms back to style, but make the default behaviour less aggressive by default (can be unleashed via config option)

Previous discussion in the bi-weekly clippy meeting for reference: https://rust-lang.zulipchat.com/#narrow/stream/257328-clippy/topic/Meeting.202021-02-23/near/227458019

Move the `upper_case_acronyms` lint back to the style group.
Only warn on fully-capitalized names by default.
Add add a clippy-config option `upper-case-acronyms-aggressive: true/false` to enabled more aggressive linting on
all substrings that could be capitalized acronyms.

59750dceb8 upper_case_acronyms: add optional aggressive mode and relax default
Moves the lint back from pedantic to style group.
The lint default now only warns on names that are completely capitalized, like "WORD"
and only if the name is longer than 2 chars (so that names where each of the letter represents a word are still distinguishable).
For example: FP (false positive) would still be "valid" and not warned about (but EOF would warn).

A "upper_case_acronyms_aggressive: true/false" config option was added that restores the original lint behaviour to warn
on any kind of camel case name that had more than one capital letter following another capital letter.

0eefa6169d upper_case_acronyms: move lint from style to pedantic lint group
The lint does point out inconsistency with the Rust naming convention,
but the fact that rustc does not warn about the inconsistency by default
means that clippy probably should not warn by default either.

Fix FP in inherent_to_string when the function has generic parameters

Minimal example of the false positive:
````
struct G;

impl G {
    fn to_string<const _N: usize>(&self) -> String {
        "G.to_string()".to_string()
    }
}

fn main() {
    let g = G;
    g.to_string::<1>();
}
````
Clippy emits an `inherent_to_string` warning, and suggests that we implement `Display` for `G` instead. However, this is not possible, since the generic parameter _N only exists in this function, not in `G` itself. This particular example uses const generics, which is where the issue is most likely to come up, but this PR skips the lint if the `to_string` function has any kind of generic parameters.

Teach SpanlessEq binding IDs

changelog: Fix collapsible_match false positive

Fixes #6740

This PR changes the way `SpanlessEq` determines whether two local variables are the same. Instead of checking that the names match, it checks that the `HirId`s match. If local bindings are declared within the expressions that are being compared, `SpanlessEq` will remember bindings that correspond to each other in a `FxHashMap<HirId, HirId>`. This makes `SpanlessEq` more flexible while also fixing false positives.

Example: `{ let x = 1; x + 2 }` is equal to `{ let y = 1; y + 2 }`.

CC `@xFrednet` I think this will resolve some concerns in #6463

ast: Keep expansion status for out-of-line module items

I.e. whether a module `mod foo;` is already loaded from a file or not.
This is a pre-requisite to correctly treating inner attributes on such modules (https://github.com/rust-lang/rust/issues/81661).

With this change AST structures for `mod` items diverge even more for AST structure for the crate root, which previously used `ast::Mod`.
Therefore this PR removes `ast::Mod` from `ast::Crate` in the first commit, these two things are sufficiently different from each other, at least at syntactic level.
Customization points for visiting a "`mod` item or crate root" were also removed from AST visitors (`fn visit_mod`).
`ast::Mod` itself was refactored away in the second commit in favor of `ItemKind::Mod(Unsafe, ModKind)`.

r? `@flip1995`

As we discussed in [here](https://rust-lang.zulipchat.com/#narrow/stream/257328-clippy/topic/Issue.20.236064/near/224647188) and [here](https://rust-lang.zulipchat.com/#narrow/stream/257328-clippy/topic/Issue.20clippy.236064/near/224746333),   I start implementing this lint from the strictest version.
In this PR, I'll allow the below two cases to pass the lint to reduce FPs.

1. Appearances of unsuffixed numeric literals in `Local` if `Local` has a type annotation, for example:
```rust
// Good.
let x: i32 = 1;

// Also good.
let x: (i32, i32) = if cond {
   (1, 2)
} else {
   (2, 3)
};
```

2. Appearances of unsuffixed numeric literals in args of `Call` or `MethodCall`  if corresponding arguments of their signature have concrete types, for example:
```rust
fn foo_mono(x: i32) -> i32 {
    x
}

fn foo_poly<T>(t: T) -> t {
    t
}

// Good.
let x = foo_mono(13);

// Still bad.
let x: i32 = foo_poly(13);
```

34b373d309 Rename HIR UnOp variants
This renames the variants in HIR UnOp from

    enum UnOp {
        UnDeref,
        UnNot,
        UnNeg,
    }

to

    enum UnOp {
        Deref,
        Not,
        Neg,
    }

Motivations:

- This is more consistent with the rest of the code base where most enum
  variants don't have a prefix.

- These variants are never used without the `UnOp` prefix so the extra
  `Un` prefix doesn't help with readability. E.g. we don't have any
  `UnDeref`s in the code, we only have `UnOp::UnDeref`.

- MIR `UnOp` type variants don't have a prefix so this is more
  consistent with MIR types.

- "un" prefix reads like "inverse" or "reverse", so as a beginner in
  rustc code base when I see "UnDeref" what comes to my mind is
  something like "&*" instead of just "*".

disallowed_methods: Support functions in addition to methods

## Context:

Hey all! I have a particular use case where I'd like to ban certain functions in a code base I work on. For example, I want to ban `Instant::now()` (among others) as we have a time service for mocking time in deterministic simulation tests. Obviously, it doesn't make sense to include a lint like this for all clippy users. Imagine my excitement when I spotted the new `disallowed_methods` lint in clippy--perfect! Unfortunately, after playing around with it for a bit, I was frustrated to realize that it didn't support functions like `Instant::now()`, so I've added support for them in this PR.

It might also make sense to rename the lint from `disallowed_methods` -> `disallowed_functions`, though I've held off from including that rename in this change, since I'm unsure of clippy's breaking change policy.

## Change

Support functions in addition to methods. In other words, support:

`disallowed_methods = ["alloc::vec::Vec::new"]` (a function) in addition to
`disallowed_methods = ["alloc::vec::Vec::leak"]` (a method).

Improve the documentation to clarify that users must specify the full qualified path for each disallowed function, which can be confusing for reexports. Include an example `clippy.toml`.

Simplify the actual lint pass so we can reuse `utils::fn_def_id`.

Cleanup path-to-local checks

changelog: none

It seemed like too much ceremony going on to check if an expression matches a variable. So I created two util functions `path_to_local(Expr) -> Option<HirId>` and `path_to_local_id(Expr, HirId) -> bool` to make this easier, and used them wherever applicable.

I changed logic in a few places to use `HirId` instead of `Symbol` where it was easy to do so. I believe this is more correct and may even fix some bugs.

I also removed some calls to `qpath_res`. This is not needed if you are only looking for a `Res::Local`.

As a note, I wanted to name the util functions in a way that encourages understanding of the HIR.

Refactor `PrimitiveTypeTable` for Clippy

I removed `PrimitiveTypeTable` and added `PrimTy::ALL` and `PrimTy::from_name` in its place. This allows Clippy to use `PrimTy::from_name` for the `builtin_type_shadow` lint, and a `const` list of primitive types is deleted from Clippy code (the goal). All changes should be a little faster, if anything.

The issue:

See this Rust playground link: https://play.rust-lang.org/?edition=2018&gist=12cb5d1e7527f8c37743b87fc4a53748

Run the above with clippy to see the following warning:

```
warning: returning the result of a `let` binding from a block
  --> src/main.rs:24:5
   |

```

Implementing the suggested fix, removing the temporary let binding,
yields a compiler error:

```

```

The fix:

Of course, clippy looks like it should already handle this edge case;
however, it appears `utils::fn_def_id` is not returning a `DefId` for
`Foo::new`. Changing the `qpath_res` lookup to use the child Path
`hir_id` instead of the parent Call `hir_id` fixes the issue.

c18d6f1ffa Rollup merge of #81176 - camsteffen:qpath-res, r=oli-obk
Improve safety of `LateContext::qpath_res`

This is my first rustc code change, inspired by hacking on clippy!

The first change is to clear cached `TypeckResults` from `LateContext` when visiting a nested item. I took a hint from [here](5e91c4ecc0/compiler/rustc_privacy/src/lib.rs (L1300)).

Clippy has a `qpath_res` util function to avoid a possible ICE in `LateContext::qpath_res`. But the docs of `LateContext::qpath_res` promise no ICE. So this updates the `LateContext` method to keep its promises, and removes the util function.

Refractor a few more types to `rustc_type_ir`

In the continuation of #79169, ~~blocked on that PR~~.

This PR:
 - moves `IntVarValue`, `FloatVarValue`, `InferTy` (and friends) and `Variance`
 - creates the `IntTy`, `UintTy` and `FloatTy` enums in `rustc_type_ir`, based on their `ast` and `chalk_ir` equilavents, and uses them for types in the rest of the compiler.

~~I will split up that commit to make this easier to review and to have a better commit history.~~
EDIT: done, I split the PR in commits of 200-ish lines each

2be935d396 Force token collection to run when parsing nonterminals
Fixes #81007

Previously, we would fail to collect tokens in the proper place when
only builtin attributes were present. As a result, we would end up with
attribute tokens in the collected `TokenStream`, leading to duplication
when we attempted to prepend the attributes from the AST node.

We now explicitly track when token collection must be performed due to
nomterminal parsing.

d4bf59b6ef size_of_in_element_count: Disable lint on division by byte-size
It is fairly common to divide some length in bytes by the byte-size of a
single element before creating a `from_raw_parts` slice or similar
operation. This lint would erroneously disallow such expressions.

Just in case, instead of simply disabling this lint in the RHS of a
division, keep track of the inversion and enable it again on recursive
division.

New Lint: inspect_then_for_each

**Work In Progress**

This PR addresses [Issue 5209](https://github.com/rust-lang/rust-clippy/issues/5209) and adds a new lint called `inspect_then_for_each`.

Current seek some guidance.

If you added a new lint, here's a checklist for things that will be
checked during review or continuous integration.

- \[x] Followed [lint naming conventions][lint_naming]
- \[x] Added passing UI tests (including committed `.stderr` file)
- \[x] `cargo test` passes locally
- \[x] Executed `cargo dev update_lints`
- \[x] Added lint documentation
- \[x] Run `cargo dev fmt`

Although there were some discussion in the issue, this PR implements the original feature. I think `cast_ptr_alignment` should exist as it is, separated from `ptr_as_ptr`.

Fix FP for `boxed_local` lint in default trait fn impl

Fix FP on default trait function implementation on `boxed_local` lint.

Maybe I checked too much when looking if `self` is carrying `Self` in its bound type.
I can't find a good test case for this, so it could be too much conservative.
Let me know if you think only detecting `self` parameter is enough.

Open question: should this lint be `pedantic` or `style`? I set it `pedantic` for now because the original post suggests using it, but I think the lint also fits well to `style`.

9f9e9f7e52 Auto merge of #6316 - ThibsG:WrongSelfConventionTraitDef, r=ebroto
Lint also in trait def for `wrong_self_convention`

Extends `wrong_self_convention` to lint also in trait definition.

By the way, I think the `wrong_pub_self_convention` [example](dd826b4626/clippy_lints/src/methods/mod.rs (L197)) is misleading.
On [playground](https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&gist=32615ab3f6009e7e42cc3754be0ca17f), it fires `wrong_self_convention`, so the example (or the lint maybe?) needs to be reworked.
The difference with `wrong_self_convention` [example](dd826b4626/clippy_lints/src/methods/mod.rs (L172)) is mainly the `pub` keyword on the method `as_str`, but the lint doesn't use the function visibility as condition to choose which lint to fire (in fact it uses the visibility of the impl item).

fixes: #6307

Before this change, finding an error when parsing a doctest would make Clippy exit without emitting an error. Now we properly catch a fatal error and ignore it.

Also, if a doctest specifies an edition in the info line, it will be used when parsing it.

Implement if-let match guards

Implements rust-lang/rfcs#2294 (tracking issue: #51114).

I probably should do a few more things before this can be merged:
- [x] Add tests (added basic tests, more advanced tests could be done in the future?)
- [x] Add lint for exhaustive if-let guard (comparable to normal if-let statements)
- [x] Fix clippy

However since this is a nightly feature maybe it's fine to land this and do those steps in follow-up PRs.

Fixing a false positive for the `match_single_binding` lint #5552

This is a fix for a false positive in the `match_single_binding` lint when using `#[cfg()]` on a branch. It is sadly a bit hacky but maybe the best solution as rust removes the other branch from the AST before we can even validate it. This fix looks at the code snippet itself and returns if it includes another thick arrow `=>` besides the one matching arm we found. This can again cause false negatives if someone has the following code:
```rust
match x {
    // => <-- Causes a false negative
    _ => 1,
}
```

I thought about making the code more complex and maybe validating against other things like the `#[cfg()]` macro but I believe that this is the best solution. This has basically switched the issue from a false positive to a false negative in a very specific case.

I'm happy to make some changes if you have any suggestions 🙃.

c1664c50b2 Auto merge of #6421 - xFrednet:4176-unreadable-literal-lint-fractal-option, r=Manishearth
Added a lint-fraction-readability flag to the configuration

This adds an option to disable the `unreadable_literal` lint for floats with a longer fraction. This allows users to write `0.100200300` without getting a warning. Fixes #4176

I have some open questions about this PR:
1. I've named the option `lint-fraction-readability` is this a good name or should I rename it to something else?
2. What should the default configuration value be?
    * The current default value is `true` as this was also the previous default.
3. Do I have to document this new option somewhere else or will it be extracted from the code comment?
4. The current fix option will also rewrite the fraction if the integer part violates the `unreadable_literal` lint it would otherwise also trigger the `inconsistent_digit_grouping` lint. Is this also okay?
    * `1.100200300` will be unaffected by the fix function
    * `100200300.100200300` will be effected and fixed to `100_200_300.100_200_300`

The project needed some getting used to but I'm happy with the result. A big thank you to `@flip1995` for giving me some pointers for this implementation and to everyone for the great introduction documentation!

Rollup merge of #6402 - camsteffen:collapsible-match, r=llogiq
Add Collapsible match lint

changelog: Add collapsible_match lint

Closes #1252
Closes #2521

This lint finds nested `match` or `if let` patterns that can be squashed together. It is designed to be very conservative to only find cases where merging the patterns would most likely reduce cognitive complexity.

Example:

```rust
match result {
    Ok(opt) => match opt {
        Some(x) => x,
        _ => return,
    }
    _ => return,
}
```
to
```rust
match result {
    Ok(Some(x)) => x,
    _ => return,
}
```

These criteria must be met for the lint to fire:

* The inner match has exactly 2 branches.
* Both the outer and inner match have a "wild" branch like `_ => ..`. There is a special case for `None => ..` to also be considered "wild-like".
* The contents of the wild branches are identical.
* The binding which "links" the matches is never used elsewhere.

Thanks to the hir, `if let`'s are easily included with this lint since they are desugared into equivalent `match`'es.

I think this would fit into the style category, but I would also understand changing it to pedantic.

cover the case where the change should be made on either side of the expression with `not_caught_by_eq_op` tests

produce the expected suggestion on the `not_caught_by_eq_op_middle_change_left` test

confirm that the previous tests still pass and update references

fix early continue bug and get `not_caught_by_eq_op_middle_change_right` passing

note that `not_caught_by_eq_op_start` already passes

fix bugs based on misunderstanding of what `Iterator::skip` does, and note that `not_caught_by_eq_op_end` now passes

add several parens tests and make some of them pass

handle parens inside `chained_binops_helper` and note that this makes several tests pass

attempt to implement if statement extraction and notice that we don't seem to handle unary ops correctly

add `maximum_unary_minus_right_tree` test and make it pass

add two tests and note one of them passes

filter out unary operations in several places, and find that the issue seems to be that we don't currently recognize the error in `multiple_comparison_types_and_unary_minus` even so.

remove filtering that was causing bad suggestions

remove tests that were deemed too much for now

f6827839c0 Move lev_distance to rustc_ast, make non-generic
rustc_ast currently has a few dependencies on rustc_lexer. Ideally, an AST
would not have any dependency its lexer, for minimizing unnecessarily
design-time dependencies. Breaking this dependency would also have practical
benefits, since modifying rustc_lexer would not trigger a rebuild of rustc_ast.

This commit does not remove the rustc_ast --> rustc_lexer dependency,
but it does remove one of the sources of this dependency, which is the
code that handles fuzzy matching between symbol names for making suggestions
in diagnostics. Since that code depends only on Symbol, it is easy to move
it to rustc_span. It might even be best to move it to a separate crate,
since other tools such as Cargo use the same algorithm, and have simply
contain a duplicate of the code.

This changes the signature of find_best_match_for_name so that it is no
longer generic over its input. I checked the optimized binaries, and this
function was duplicated at nearly every call site, because most call sites
used short-lived iterator chains, generic over Map and such. But there's
no good reason for a function like this to be generic, since all it does
is immediately convert the generic input (the Iterator impl) to a concrete
Vec<Symbol>. This has all of the costs of generics (duplicated method bodies)
with no benefit.

Changing find_best_match_for_name to be non-generic removed about 10KB of
code from the optimized binary. I know it's a drop in the bucket, but we have
to start reducing binary size, and beginning to tame over-use of generics
is part of that.

Change `redundant_pattern_matching` to also lint `std::task::Poll`

`reduntant_pattern_matching` currently lints pattern matching on `Option` and `Result` where the `is_variant` utility methods could be used instead: `is_some`, `is_none`, `is_ok`, `is_err`. This PR extends this behaviour to `std::task::Poll`, suggesting the methods `is_pending` and `is_ready`.

Motivation: The current description of `redundant_pattern_matching` mentions

> It's more concise and clear to just use the proper utility function

which in my mind applies to `Poll` as well.

Drop support for all cloudabi targets

`cloudabi` is a tier-3 target, and [it is no longer being maintained upstream][no].

This PR drops supports for cloudabi targets. Those targets are:
* aarch64-unknown-cloudabi
* armv7-unknown-cloudabi
* i686-unknown-cloudabi
* x86_64-unknown-cloudabi

Since this drops supports for a target, I'd like somebody to tag `relnotes` label to this PR.

Some other issues:
* The tidy exception for `cloudabi` crate is still remained because
  * `parking_lot v0.9.0` and `parking_lot v0.10.2` depends on `cloudabi v0.0.3`.
  * `parking_lot v0.11.0` depends on `cloudabi v0.1.0`.

3a648ffc02 Rollup merge of #78836 - fanzier:struct-and-slice-destructuring, r=petrochenkov
Implement destructuring assignment for structs and slices

This is the second step towards implementing destructuring assignment (RFC: rust-lang/rfcs#2909, tracking issue: #71126). This PR is the second part of #71156, which was split up to allow for easier review.

Note that the first PR (#78748) is not merged yet, so it is included as the first commit in this one. I thought this would allow the review to start earlier because I have some time this weekend to respond to reviews. If ``@petrochenkov`` prefers to wait until the first PR is merged, I totally understand, of course.

This PR implements destructuring assignment for (tuple) structs and slices. In order to do this, the following *parser change* was necessary: struct expressions are not required to have a base expression, i.e. `Struct { a: 1, .. }` becomes legal (in order to act like a struct pattern).

Unfortunately, this PR slightly regresses the diagnostics implemented in #77283. However, it is only a missing help message in `src/test/ui/issues/issue-77218.rs`. Other instances of this diagnostic are not affected. Since I don't exactly understand how this help message works and how to fix it yet, I was hoping it's OK to regress this temporarily and fix it in a follow-up PR.

Thanks to ``@varkor`` who helped with the implementation, particularly around the struct rest changes.

Add `let_underscore_drop`

This line generalizes `let_underscore_lock` (#5101) to warn about any initializer expression that implements `Drop`.

So, for example, the following would generate a warning:
```rust
struct Droppable;
impl Drop for Droppable {
    fn drop(&mut self) {}
}
let _ = Droppable;
```

I tried to preserve the original `let_underscore_lock` functionality in the sense that the warning generated for
```rust
let _ = mutex.lock();
```
should be unchanged.

rustc_ast: Do not panic by default when visiting macro calls

Panicking by default made sense when we didn't have HIR or MIR and everything worked on AST, but now all AST visitors run early and majority of them have to deal with macro calls, often by ignoring them.

The second commit renames `visit_mac` to `visit_mac_call`, the corresponding structures were renamed earlier in https://github.com/rust-lang/rust/pull/69589.

The previous example used in `cargo_common_metadata`  included an authors field, even though the comment says it doesn't. And thus doesn't actually demonstrate an example of how the lint fails.

This removes that authors field from the _bad_ example and suggest to fix the _bad_ example by adding the authors field

"Respect" enums in `interior_mutable_const`

fixes #3962
fixes #3825

Hello,

It might not be a good idea to submit another relatively large PR while I have an opened PR; but, I've finished this anyway. This may be able to wait for months.

Note: the code uses the MIR interpreter, which the author of #3962 thought unlikely to be a solution. This might be over-engineering; but, I think it's important to be able to work with the 'http' crate (#3825). (And, I don't want to write a MIR visitor)

Provide diagnostic suggestion in ExprUseVisitor Delegate

The [Delegate trait](981346fc07/compiler/rustc_typeck/src/expr_use_visitor.rs (L28-L38)) currently use `PlaceWithHirId` which is composed of Hir `Place` and the
corresponding expression id.

Even though this is an accurate way of expressing how a Place is used,
it can cause confusion during diagnostics.

Eg:

```
let arr : [String; 5];

let [a, ...]     =   arr;
 ^^^ E1 ^^^      =  ^^E2^^
 ```

 Here `arr` is moved because of the binding created E1. However, when we
 point to E1 in diagnostics with the message `arr` was moved, it can be
 confusing.  Rather we would like to report E2 to the user.

 Closes: https://github.com/rust-lang/project-rfc-2229/issues/20

Add lint for 'field_reassign_with_default` #568

changelog: Add lint for field_reassign_with_default that checks if mutable object + field modification is used to edit a binding initialized with Default::default() instead of struct constructor.

Fixes #568

Notes:
- Checks for reassignment of one or more fields of a binding initialized with Default::default().
- Implemented using EarlyLintPass, might be future proofed better with LateLintPass.
- Does not trigger if Default::default() is used via another type implementing Default.
- This is a re-open of [PR#4761](https://github.com/rust-lang/rust-clippy/pull/4761), but I couldn't figure out how to re-open that one so here's a new one with the requested changes :S

Use const sym where possible

I ran a regex search and replace to use const `sym` values where possible. This should give some performance boost by avoiding string interning at runtime.

Con: It is not as consistent as always using `sym!`.

I also changed an internal lint to suggest using `sym::{}`, making an assumption that this will always work for diagnostic items.

This implements lint for `::from_iter()` from #5679 not the general issue (`std::ops::Add::add`, etc.).
