…gations

…own-linux-gnueabihf Add SanitizerSet::ADDRESS to the supported_sanitizers for the arm-unknown-linux-gnueabihf and armv7-unknown-linux-gnueabihf targets. The AddressSanitizer is already enabled on the armv7-linux-androideabi platform, which shares the same ARM architecture. There is no reason these Linux GNU targets should not also support it, as the underlying LLVM support for ASan on 32-bit ARM is already in place.

Add a regression test for RUST-150898 to make users aware that if this test fails, they may encounter unusual behavior elsewhere. Original repro authored by dianqk.

So we do not need to disambiguate considering parents

…-rename, r=petrochenkov delegation: rename `Self` generic param to `This` in recursive delegations This PR supports renaming of `Self` generic parameter to `This` in recursive delegations scenario, this allows propagation of `This` as we rely on `Self` naming to check whether it is implicit Self of a trait. Comment with a bit deeper explanation is in `uplift_delegation_generic_params`. Part of rust-lang#118212. r? @petrochenkov

@petrochenkov

Some cleanups around per parent disambiguators r? @petrochenkov follow-up to rust-lang#155547 The two remaining uses are * resolve_bound_vars, where it is a reasonable way to do it instead of having another field in the visitor that needs to get scoped (set & reset) every time we visit an opaque type. May still change that at some point, but it's not really an issue * `create_def` in the resolver: will get removed together with my other refactorings for `node_id_to_def_id` (making that per-owner)

@glaubitz

…iser rustc_codegen_ssa: Define ELF flag value for sparc-unknown-linux-gnu Currently, attempting to build this target using Ubuntu/Debian's sparc64-multilib toolchain results in the following link error ([full log](https://github.com/taiki-e/atomic-maybe-uninit/actions/runs/22798868888/job/66137493862#step:15:442)): ``` = note: /usr/lib/gcc-cross/sparc64-linux-gnu/13/../../../../sparc64-linux-gnu/bin/ld: unknown architecture of input file `/home/runner/work/atomic-maybe-uninit/atomic-maybe-uninit/target/sparc-unknown-linux-gnu/debug/deps/rustcYzaDYW/symbols.o' is incompatible with sparc:v8plus output ``` This appears to be caused by the required e_flag being missing and can be fixed by setting `EF_SPARC_32PLUS`. Tested using rustc with this patch applied and qemu-user (taiki-e/atomic-maybe-uninit@57d7e7f, [log](https://github.com/taiki-e/atomic-maybe-uninit/actions/runs/22798793270/job/66137298093)).

…w-suggestion-v2, r=JohnTitor Do not suggest borrowing enclosing calls for nested where-clause obligations In rust-lang#155088, the compiler was blaming the whole call expr instead of the value that actually failed the trait bound, so for foo(&[String::from("a")]) it was suggesting stuff like &foo(...). I changed the suggestion logic so it only emits borrow help if the expr it found actually matches the failed self type, and used the same check for the “similar impl exists” help too. So now the compiler should give the normal error + required bound note. Fix rust-lang#155088

…inarycat rustdoc: Fix Managarm C Library name in cfg pretty printer Like rust-lang#155293, this was introduced in rust-lang#154328. Unlike that PR, I don't think there's any need to backport, because this cfg is not used anywhere in the standard library. (I searched for `"mlibc"`, the only place it's used in rust-lang/rust is the HTML doc test.) #### Other Minor Fixes Remove a FIXME comment in the pretty printer, `os = "none"` is always bare metal: https://github.com/rust-lang/rust/blob/d227e48c560e915fe7c0b8b3e821680a3a0ba739/compiler/rustc_target/src/spec/mod.rs#L3179 Fix a comment typo, ignore another typo in vendored sources.

Enable AddressSanitizer on arm-unknown-linux-gnueabihf and armv7-unknown-linux-gnueabihf Add SanitizerSet::ADDRESS to the supported_sanitizers for the arm-unknown-linux-gnueabihf and armv7-unknown-linux-gnueabihf targets. The AddressSanitizer is already enabled on the armv7-linux-androideabi platform, which shares the same ARM architecture. There is no reason these Linux GNU targets should not also support it, as the underlying LLVM support for ASan on 32-bit ARM is already in place.

…=dianqk test: Add a regression test for Apple platforms aborting on `free` Add a regression test for rust-lang#150898 to make users aware that if this test failures, they may encounter unusual behavior elsewhere.

…c, r=wesleywiser Fix tier level for 5 thumb bare-metal ARM targets The spec files for 5 Thumb-mode bare-metal ARM targets incorrectly set tier: Some(2), while the documentation correctly lists them as Tier 3. This mismatch was introduced in PR rust-lang#150556 — the intent was Tier 2 eventually, but these targets should sit at Tier 3 until a proper Tier 3 → Tier 2 promotion MCP is submitted and approved. This PR changes tier: Some(2) → Some(3) in the following spec files, making them consistent with the docs: thumbv7a-none-eabi thumbv7a-none-eabihf thumbv7r-none-eabi thumbv7r-none-eabihf thumbv8r-none-eabihf PS: No doc changes needed — they already correctly state Tier 3. r?

…typo, r=wesleywiser Fix typo by removing extra 'to' Fixes rust-lang#155695 Fix a typo in the `std::convert` module documentation by removing an extra "to" in the module-level docs.

…chenkov Remove `AllVariants` workaround for rust-analyzer Part of rust-lang#155677 Removes the `ALL_VARIANTS` alias added to work around rust-analyzer not supporting `#![feature(macro_derive)]`, which has since been fixed (rust-lang/rust-analyzer/issues/21043).

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.

Overall result: ❌✅ regressions and improvements - please read:

Our benchmarks found a performance regression caused by this PR.
This might be an actual regression, but it can also be just noise.

Next Steps:

If the regression was expected or you think it can be justified,
please write a comment with sufficient written justification, and add
@rustbot label: +perf-regression-triaged to it, to mark the regression as triaged.
If you think that you know of a way to resolve the regression, try to create
a new PR with a fix for the regression.
If you do not understand the regression or you think that it is just noise,
you can ask the @rust-lang/wg-compiler-performance working group for help (members of this group
were already notified of this PR).
