Gelbpunkt:mips64-unknown-linux-muslabi64-target-maintainer, r=jieyouxu Add target maintainer information for mips64-unknown-linux-muslabi64 The `mips64-unknown-linux-muslabi64` target is currently rather broken, but I'm working on getting it fixed so that it can at least be used again. While I can't commit to maintaining the LLVM side of this target, I don't mind looking into any other MIPS or musl-related issues that arise with this target. See e.g. rust-lang/rust#143409 for some rustc fixes I have in the pipeline and https://github.com/rust-lang/libc/pull/4509, https://github.com/rust-lang/libc/pull/4527, https://github.com/rust-lang/libc/pull/4528, https://github.com/rust-lang/libc/pull/4529, https://github.com/rust-lang/libc/pull/4530 for fixing the libc definitions for this target. I'm adding myself as a maintainer mostly due to [this interaction](https://github.com/rust-lang/libc/pull/4530#issuecomment-3045912645). LLVM support has been a concern for these targets in the past, but it shouldn't hurt to have a nominal maintainer for these even if they remain tier 3. From my experience, LLVM for MIPS is working well nowadays unless you decide to use LLD, which is horribly broken on MIPS.
2025-07-08Rollup merge of #143620 - Muscraft:remove-newline, r=compiler-errorsMatthias Krüger-1/+1
fix: Remove newline from multiple crate versions note While working on getting `annotate-snippets` to match `rustc`, `annotate-snippets` was adding an extra new line after [this line](https://github.com/rust-lang/rust/blob/a2d45f73c70d9dec57140c9412f83586eda895f8/tests/run-make/crate-loading/multiple-dep-versions.stderr#L9) for [`run-make/crate-loading/multiple-dep-versions.rs`](https://github.com/rust-lang/rust/blob/a2d45f73c70d9dec57140c9412f83586eda895f8/tests/run-make/crate-loading/multiple-dep-versions.rs). I found out this was because there was an explicit `\n` in the message that `annotate-snippets` was respecting, while `rustc` was [skipping it](https://github.com/rust-lang/rust/blob/2f8eeb2bba86b8f457ec602c578473c711f85628/compiler/rustc_errors/src/emitter.rs#L1542).

Update intro blurb in `wasm32-wasip1` docs I was reading over this documentation in light of the effort to enlist more maintainers for Tier 2 targets and figured it was time for a refresh of this documentation now that historical renames/etc have all become a thing of the past. No new major changes to this documentation, mostly just wanted to update it and reflect the modern status quo for this target.

obi1kenobi:pg/target-feature-not-unsafe-rustdoc-json, r=aDotInTheVoid Don't mark `#[target_feature]` safe fns as unsafe in rustdoc JSON. Fixes https://github.com/rust-lang/rust/issues/142655 by explicitly checking whether functions are safe but using `#[target_feature]`, instead of relying on the `FnHeader::is_unsafe()` method which considers such functions unsafe. I don't believe this merits a bump of the rustdoc JSON `FORMAT_VERSION` constant, since the format is unchanged and this is just a small bugfix. r? aDotInTheVoid

Point to correct argument in Func Call when Self type fails trait bound Fixes rust-lang/rust#143336 When a trait bound fails due to the `Self` type parameter, `adjust_fulfillment_errors` now correctly points to the corresponding function argument instead of incorrectly pointing to other arguments. This is because `Call` may also need to handle the `self` parameter, and not just `MethodCall` needs to be handled, as rust-lang/rust#143336. r? compiler

2025-07-07Auto merge of #143182 - xdoardo:more-addrspace, r=workingjubileebors-170/+416
Allow custom default address spaces and parse `p-` specifications in the datalayout string Some targets, such as CHERI, use as default an address space different from the "normal" default address space `0` (in the case of CHERI, [200 is used](https://www.cl.cam.ac.uk/techreports/UCAM-CL-TR-877.pdf)). Currently, `rustc` does not allow to specify custom address spaces and does not take into consideration [`p-` specifications in the datalayout string](https://llvm.org/docs/LangRef.html#langref-datalayout). This patch tries to mitigate these problems by allowing targets to define a custom default address space (while keeping the default value to address space `0`) and adding the code to parse the `p-` specifications in `rustc_abi`. The main changes are that `TargetDataLayout` now uses functions to refer to pointer-related informations, instead of having specific fields for the size and alignment of pointers in the default address space; furthermore, the two `pointer_size` and `pointer_align` fields in `TargetDataLayout` are replaced with an `FxHashMap` that holds info for all the possible address spaces, as parsed by the `p-` specifications. The potential performance drawbacks of not having ad-hoc fields for the default address space will be tested in this PR's CI run. r? workingjubilee
