feat: Add a "Unmerge match arm" assist to split or-patterns inside match expressions
Fixes#13072.
The way I implemented it it leaves the `OrPat` in place even if there is only one pattern now but I don't think something will break because of that, and when more code will be typed we'll parse it again anyway. Removing it (but keeping the child pattern) is hard, I don't know how to do that.
Use object instead of LLVM for reading bitcode from rlibs
Together with changes I plan to make as part of https://github.com/rust-lang/rust/pull/97485 this will allow entirely removing usage of LLVM's archive reader and thus allow removing `archive_ro.rs` and `ArchiveWrapper.cpp`.
Use posix_spawn for absolute paths on macOS
Currently, on macOS, Rust never uses the fast posix_spawn path if a
directory change is requested, due to a bug in Apple's libc. However, the
bug is only triggered if the program is a relative path.
This PR makes it so that the fast path continues to work if the program
is an absolute path or a lone filename.
This was an alternative proposed in https://github.com/rust-lang/rust/pull/80537#issue-776674009, and it makes a measurable performance difference in some of my code that spawns thousands of processes.
Add next_up and next_down for f32/f64 - take 2
This is a revival of https://github.com/rust-lang/rust/pull/88728 which staled due to inactivity of the original author. I've address the last review comment.

Move empty diagnostics workaround back into the server
This only touches on the diagnostics in one place instead of multiple as was previously done, since all published diagnostics will go through this code path anyways.
Closes https://github.com/rust-lang/rust-analyzer/issues/13130
Remove auto-config patching from the VSCode client
This was introduced 4 months ago when we drastically changed the config keys. I'd like to remove this given I always felt uneasy doing edits to a users config from within r-a, and by now most if not all users should've swapped to a new enough version of r-a that should've updated their configs.
The extension will continue to work fine even with the outdated keys afterwards since we still do patching server side as well, and that one we'll have to support for quite some more time (if not until a proper 1.0 release where I assume we can allow ourselves some more user facing breakage)
(There also might've been a small bug in here that prevented users with certain outdated keys to prevent them from enabling certain keys for some reason)
session: stabilize split debuginfo on linux
Stabilize the `-Csplit-debuginfo` flag...
- ...on Linux for all values of the flag. Split DWARF has been implemented for a few months, hasn't had any bug reports and has had some promising benchmarking for incremental debug build performance.
- ..on other platforms for the default value. It doesn't make any sense that `-Csplit-debuginfo=packed` is unstable on Windows MSVC when that's the default behaviour, but keep the other values unstable.
Avoid reporting overflow in `is_impossible_method`
Fixes#100620
We're evaluating a new predicate in a different param-env than it was checked during typeck, so be more careful about handling overflow errors. Instead of using `FulfillmentCtxt`, using `InferCtxt::evaluate_obligation` by itself will give us back the overflow error, so we can throw it away properly.
This may give us more false-positives, but it doesn't regress the `<HashMap as Iterator>::rev` example that originally motivated adding `is_impossible_method` in the first place.
Make use of NoHash hashing for FileId and CrateId
Both of these are mere integers so there is nothing to hash here.
Ideally we would use this for `la_arena::Idx` too, but that doesn't work due to the orphan rule, and `la_arena` is unfortunately a public library so we can't really do much here... Unless we remove the trait restriction but I'd like not to
internal: Re-export standard semantic token types and mods
Should help in preventing future occurences of #13099 by having all token types and mods come through the same place
