Add new `tyalias` intra-doc link disambiguator Fixes https://github.com/rust-lang/rust/issues/146855. Alternative to rust-lang/rust#146866. This adds support for a new disambiguator: `tyalias`. I think it's common enough to have type aliases nowaday, so no reason to not be able to have a disambiguator for them. cc ``@fmease`` r? lolbinarycat
2025-09-26Rollup merge of #146758 - mati865:amd64_mingw_no_rs_objects, r=petrochenkovMatthias Krüger-0/+2
Stop linking rs{begin,end} objects on x86_64-*-windows-gnu Until now, x86_64-pc-windows-gnu linked `rsbegin.o` and `rsend.o` just like i686-pc-windows-gnu, even though they were no-ops for it. This was likely done for the simplicity back when it was introduced. Today the things are different and these startup/end objects harm other features, like `build-std`. Given the demotion of i686-pc-windows-gnu from tier 1, there is no point in hurting x86_64-pc-windows-gnu, which remains a tier 1. The files are still shipped in case downstream crates expect them, as in case of the unmaintained `xargo`. Fixes https://github.com/rust-lang/rust/issues/146739
2025-09-26Rollup merge of #146523 - thejpster:demote-armebv7r-targets, r=jackh726Matthias Krüger-3/+3
Demote both armebv7r-none-* targets. OK, slightly more controversial than https://github.com/rust-lang/rust/pull/146520 and https://github.com/rust-lang/rust/pull/146522 - I'd like to drop the bare-metal **big-endian** Armv7-R targets down to Tier 3. The reason is simple - we cannot test them in https://github.com/rust-embedded/cortex-ar/. This because QEMU support for Big Endian Armv7-R is broken. I tried quite hard, but all the strings I printed with semihosting came out byte swapped (or "etybawa depp") because of how QEMU kludges the access to memory in big-endian mode. The target also has only a single maintainer. Although, if ````@chrisnc```` wants to put up a case for keeping it at Tier 2 though, I'm happy to hear it! This PR wil be rebased once https://github.com/rust-lang/rust/pull/146419 completes the queue.

2025-09-25Rollup merge of #141032 - petrosagg:extract-if-ub, r=joboetMatthias Krüger-0/+10
avoid violating `slice::from_raw_parts` safety contract in `Vec::extract_if` The implementation of the `Vec::extract_if` iterator violates the safety contract adverized by `slice::from_raw_parts` by always constructing a mutable slice for the entire length of the vector even though that span of memory can contain holes from items already drained. The safety contract of `slice::from_raw_parts` requires that all elements must be properly initialized. As an example we can look at the following code: ```rust let mut v = vec![Box::new(0u64), Box::new(1u64)]; for item in v.extract_if(.., |x| **x == 0) { drop(item); } ``` In the second iteration a `&mut [Box<u64>]` slice of length 2 will be constructed. The first slot of the slice contains the bitpattern of an already deallocated box, which is invalid. This fixes the issue by only creating references to valid items and using pointer manipulation for the rest. I have also taken the liberty to remove the big `unsafe` blocks in place of targetted ones with a SAFETY comment. The approach closely mirrors the implementation of `Vec::retain_mut`. **Note to reviewers:** The diff is easier to follow with whitespace hidden.

r=rustdoc rustdoc: hide `#[repr]` if it isn't part of the public ABI > [!IMPORTANT] > Temporarily stacked on top of PR https://github.com/rust-lang/rust/pull/146527; only the last commit is relevant! Follow-up to rust-lang/rust#115439. Unblocks rust-lang/rust#116743, CC ``@dtolnay.`` Fixes rust-lang/rust#66401. Fixes rust-lang/rust#128364. Fixes rust-lang/rust#137440. Only display the representation `#[repr(REPR)]` (where `REPR` is not `Rust` or `transparent`) of a given type if none of its variants (incl. the synthetic variants of structs) are `#[doc(hidden)]` and all of its fields are public and not `#[doc(hidden)]` since it's likely not meant to be considered part of the public ABI otherwise. `--document-{private,hidden}-items` works as expected in this context, too. Moreover, we now also factor in the presence of `#[doc(hidden)]` when checking whether to show `repr(transparent)` or not.
