It uses the file metadata on Unix with a fallback for files incorrectly reported as zero-sized. It uses `GetFileSizeEx` on Windows. This reduces the number of syscalls needed for determining the file size of an open file from 3 to 1.
It can only describe the inner workings of the default implementation, other implementations might not be implemented using seeks at all.
The current default plain, tends to create non-uniform import blocks over time, some being relative, some being absolute. I believe we should encourage a different default here.
By removing the cache.
Previously only the open delimiter's span was set, and this caused... weird problems.
…egrated-benchmarks internal: fix `integrated_benchmarks` to make actual edits
fix: Correctly set the span of the proc_macro crate's Group delimiters
fix: Fix cache problems with lints level
minor: Support `transmute_unchecked` intrinsic for mir-eval
Remove rust-analyzer.vs from other editors
The implementation delegates to `<ByteStr as Display>::fmt`. Link: rust-lang/libs-team#550 Link: rust-lang#139984.
It wasn't inside the source, because there was no source map.
…rmation instead of syntactical hacks And rename it to `is_inside_macro_call()` accordingly.
fix: Properly implement `might_be_inside_macro_call()` using semantic information instead of syntactical hacks
…austiveness fix: Normalize when checking for uninhabited types for pattern exhaustiveness checking
fixes: ide-assists, generate_new indent loses
Change import prefix default to be by crate
…it-impl-indent fix: ide-assists, generate mut trait impl indent
…macro-hir fix: Fix IDE resolution of item macros
…ross,bjorn3 Stabilize `repr128` ## Stabilisation report The `repr128` feature ([tracking issue](rust-lang#56071)) allows the use of `#[repr(u128)]` and `#[repr(i128)]` on enums in the same way that other primitive representations such as `#[repr(u64)]` can be used. For example: ```rust #[repr(u128)] enum Foo { One = 1, Two, Big = u128::MAX, } #[repr(i128)] enum Bar { HasThing(u16) = 42, HasSomethingElse(i64) = u64::MAX as i128 + 1, HasNothing, } ``` This is the final part of adding 128-bit integers to Rust ([RFC 1504](https://rust-lang.github.io/rfcs/1504-int128.html)); all other parts of 128-bit integer support were stabilised in rust-lang#49101 back in 2018. From a design perspective, `#[repr(u128)]`/`#[repr(i128)]` function like `#[repr(u64)]`/`#[repr(i64)]` but for 128-bit integers instead of 64-bit integers. The only differences are: - FFI safety: as `u128`/`i128` are not currently considered FFI safe, neither are `#[repr(u128)]`/`#[repr(i128)]` enums (I discovered this wasn't the case while drafting this stabilisation report, so I have submitted rust-lang#138282 to fix this). - Debug info: while none of the major debuggers currently support 128-bit integers, as of LLVM 20 `rustc` will emit valid debuginfo for both DWARF and PDB (PDB makes use of the same natvis that is also used for all enums with fields, whereas DWARF has native support). Tests for `#[repr(u128)]`/`#[repr(i128)]` enums include: - [ui/enum-discriminant/repr128.rs](https://github.com/rust-lang/rust/blob/385970f0c1fd0c09bac426b02f38300c0b1ba9a2/tests/ui/enum-discriminant/repr128.rs): checks that 128-bit enum discriminants have the correct values. - [debuginfo/msvc-pretty-enums.rs](https://github.com/rust-lang/rust/blob/385970f0c1fd0c09bac426b02f38300c0b1ba9a2/tests/debuginfo/msvc-pretty-enums.rs): checks the PDB debuginfo is correct. - [run-make/repr128-dwarf](https://github.com/rust-lang/rust/blob/385970f0c1fd0c09bac426b02f38300c0b1ba9a2/tests/run-make/repr128-dwarf/rmake.rs): checks the DWARF debuginfo is correct. Stabilising this feature does not require any changes to the Rust Reference as [the documentation on primitive representations](https://doc.rust-lang.org/nightly/reference/type-layout.html#r-layout.repr.primitive.intro) already includes `u128` and `i128`.

Path::with_extension: show that it adds an extension where one did no… …t exist I think the times I encountered this, I had to check first if files without extensions were added, since all examples only had files with existing extensions. Also, this replaced example already has a similar example below.
clean up old rintf leftovers As usual stdarch needed special treatment due to rust-lang/stdarch#1655, and apparently I forgot to clean up these leftovers here. They can be removed now.
Add `rustc_diagnostic_item` to `sys::Mutex` methods For an ongoing project for adding a concurrency model checker to Miri we need to be able to intercept locking/unlocking operations on standard library mutexes. This PR adds diagnostic items to the relevant calls `lock`, `try_lock` and `unlock` for the `sys::Mutex` implementation on the targets we care about. This PR also makes the internals of `pthread::Mutex` less public, to reduce the chance of anyone locking/unlocking a mutex without going through the intercepted methods. r? `@RalfJung`

…Void Add eholk to compiler reviewer rotation Now that we have work queue limits on triagebot, I'm happy to share some of the review load. r? `@wesleywiser`
