2025-03-27Rollup merge of #139010 - madsmtm:parse-xcrun-better, r=wesleywiserJacob Pratt-6/+12
Improve `xcrun` error handling The compiler invokes `xcrun` on macOS when linking Apple targets, to find the Xcode SDK which contain all the necessary linker stubs. The error messages that `xcrun` outputs aren't always that great though, so this PR tries to improve that by providing extra context when an error occurs. Fixes https://github.com/rust-lang/rust/issues/56829. Fixes https://github.com/rust-lang/rust/issues/84534. Part of https://github.com/rust-lang/rust/issues/129432. See also the alternative https://github.com/rust-lang/rust/pull/131433. Tested on: - `x86_64-apple-darwin`, MacBook Pro running Mac OS X 10.12.6 - With no tooling installed - With Xcode 9.2 - With Xcode 9.2 Commandline Tools - `aarch64-apple-darwin`, MacBook M2 Pro running macOS 14.7.4 - With Xcode 13.4.1 - With Xcode 16.2 - Inside `nix-shell -p xcbuild` (nixpkgs' `xcrun` shim) - `aarch64-apple-darwin`, VM running macOS 15.3.1 - With no tooling installed - With Xcode 16.2 Commandline Tools ``@rustbot`` label O-apple r? compiler CC ``@BlackHoleFox`` ``@thomcc``

I've intentionally used slightly vague language ("roughly"), as we don't want to guarantee the exact invocation of `xcrun`, just hint that it's close to that.

r=compiler-errors Add target maintainer information for powerpc64-unknown-linux-musl We intend to fix the outstanding issues on the target and eventually promote it to tier 2. We have the capacity to maintain this target in the future and already perform regular builds of rustc for this target. Currently, all host tools except miri build fine, but I have a patch for libffi-sys to make miri also compile fine for this target that is [pending review](https://github.com/tov/libffi-rs/pull/100). While at it, add an option for the musl root for this target. I also added a kernel version requirement, which is rather arbitrarily chosen, but it matches our tier 2 powerpc64le-unknown-linux-musl target so I think it is a good fit.

Shourya742:2025-02-15-change-config.toml-to-bootstrap.toml, r=onur-ozkan,jieyouxu,kobzol change config.toml to bootstrap.toml Currently, both Bootstrap and Cargo uses same name as their configuration file, which can be confusing. This PR is based on a discussion to rename `config.toml` to `bootstrap.toml` for Bootstrap. Closes: https://github.com/rust-lang/rust/issues/126875. I have split the PR into atomic commits to make it easier to review. Once the changes are finalized, I will squash them. I am particularly concerned about the changes made to modules that are not part of Bootstrap. How should we handle those changes? Should we ping the respective maintainers?

Remove i586-pc-windows-msvc See [MCP 840](https://github.com/rust-lang/compiler-team/issues/840). I left a specialized error message that should help users that hit this in the wild (for example, because they use it in their CI). ``` error: Error loading target specification: the `i586-pc-windows-msvc` target has been removed. Use the `i686-pc-windows-msvc` target instead. Windows 10 (the minimum required OS version) requires a CPU baseline of at least i686 so you can safely switch. Run `rustc --print target-list` for a list of built-in targets ``` ``@workingjubilee`` ``@calebzulawski`` fyi portable-simd uses this target in CI, if you wanna remove it already before this happens

Add minimal platform support documentation for powerpc-unknown-linux-gnuspe Per https://github.com/rust-lang/rust/pull/137860#issuecomment-2692358259, add minimal platform support documentation, including a brief summary and links to more detailed information about this target. The added documentation is minimal. This is somewhat similar to [powerpc-unknown-openbsd, which also has no target maintainer](https://doc.rust-lang.org/nightly/rustc/platform-support/powerpc-unknown-openbsd.html). The rest of the template is left to target maintainers.

Update docs for default features of wasm targets LLVM 20 enabled the `nontrapping-fptoint` and `bulk-memory` features by default, so this updates the corresponding documentation for the `wasm32-*` targets (which all point to `wasm32-unknown-unknown`). Closes #137315 with a doc update for the doc part.

r=chenyukang,workingjubilee Add cygwin target. This PR simply adds cygwin target together with msys2 target, based on ````@ookiineko```` 's (the account has been deleted) [work](https://github.com/ookiineko-cygport/rust) on cygwin target. My full work is here: https://github.com/rust-lang/rust/compare/master...Berrysoft:rust:dev/cygwin I have succeeded in building a new rustc for cygwin target, and eventually distributed a new version of [fish-shell](https://github.com/Berrysoft/fish-shell/releases) (rewritten by Rust) for MSYS2. I will open a new PR to fix std if this PR is accepted.

i686-linux-android: increase CPU baseline to Pentium 4 (without an actual change As per ``@maurer's`` [comment](https://github.com/rust-lang/rust/issues/136495#issuecomment-2648743078), this shouldn't actually change anything since we anyway add a bunch of extensions that bump things up way beyond Pentium 4. But Pentium 4 is consistent with the other i686 targets and I don't know enough about the exact sequence of CPU generations to be confident with more than this. ;)
