Add mipsel maintainer
|
|
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.

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.

Rework `--print` options documentation
This PR reworks the `--print` options documentation, by making it more like codegen options with a dedicated page.
I also added some examples and split some paragraph into multiple paragraph since we now have more place.

Only use `DIST_TRY_BUILD` for try jobs that were not selected explicitly
Some CI jobs (x64 Linux, ARM64 Linux and x64 MSVC) use the `opt-dist` tool to build an optimized toolchain using PGO and BOLT. When performing a default try build for x64 Linux, in most cases we want to run perf. on that artifact. To reduce the latency of this common use-case, `opt-dist` skips building several components not needed for perf., and it also skips running post-optimization tests, when it detects that the job is executed as a try job (not a merge/auto job).
This is useful, but it also means that if you *want* to run the tests, you had to go to `jobs.yml` and manually comment this environment variable, create a WIP commit, do a try build, and then remove the WIP commit, which is annoying (in the similar way that modifying what gets run in try builds was annoying before we had the `try-job` annotations).
I thought that we could introduce some additional PR description marker like `try-job-run-tests`, but it's hard to discover that such things exist.
Instead, I think that there's a much simpler heuristic for determining whether `DIST_TRY_BUILD` should be used (that I implemented in this PR):
- If you do just ``@bors` try`, without any custom try jobs selected, `DIST_TRY_BUILD` will be activated, to finish the build as fast as possible.
- If you specify any custom try jobs, you are most likely doing experiments and you want to see if tests pass and everything builds as it should. The `DIST_TRY_BUILD` variable will thus *not* be set in this case.
In this way, if you want to run dist tests, you can just add the `try-job: dist-x86_64-linux` line to the PR description, and you don't need to create any WIP commits.

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?

Stabilize `asm_goto` feature gate
Stabilize `asm_goto` feature (tracked by #119364). The issue will remain open and be updated to track `asm_goto_with_outputs`.
Reference PR: https://github.com/rust-lang/reference/pull/1693
# Stabilization Report
This feature adds a `label <block>` operand type to `asm!`. `<block>` must be a block expression with type unit or never. The address of the block is substituted and the assembly may jump to the block. When block completes the `asm!` block returns and continues execution.
The block starts a new safety context and unsafe operations within must have additional `unsafe`s; the effect of `unsafe` that surrounds `asm!` block is cancelled. See https://github.com/rust-lang/rust/issues/119364#issuecomment-2316037703 and https://github.com/rust-lang/rust/pull/131544.
It's currently forbidden to use `asm_goto` with output operands; that is still unstable under `asm_goto_with_outputs`.
Example:
```rust
unsafe {
asm!(
"jmp {}",
label {
println!("Jumped from asm!");
}
);
}
```

- tests/ui/asm/x86_64/goto-block-safe.stderr
