`DEVELOPER_DIR` is the standard environment variable for overriding the
Xcode version, there is no need to invoke `xcode-select --switch`
manually to do this.
The variable is documented in both `man xcode-select` and `man xcrun`.
Free disk space on Windows 2025 runners
I've managed to reduce the time deletion takes by:
- Using powershell, which is generally faster for filesystem operations than msys2
- Performing deletions concurrently then waiting for them all to complete
It still takes 2-10 mins but that's not too bad.
Unfortunately, the separate spellcheck GHA workflow does not really work
with homu, if we would like to enforce the invariant that PR CI is a
subset of Full CI (modulo carve outs).
This is not prejudice against a reland of a `typos`-based spellcheck, it
just probably has to go through the "usual" CI flow with bootstrap, so
that it can work with homu.
Add an aarch64-msvc build running on ARM64 Windows
Resurrecting rust-lang/rust#126341
Per <https://github.com/rust-lang/rfcs/pull/3817> we intend to promote `aarch64-pc-windows-msvc` to Tier 1. As part of that work, we are adding a pre-merge CI job to validate that changes do not break this target.
Additionally, for consistency, the `dist-aarch64-msvc` job will also be run on Arm64 Windows runners.

Assign dependency bump PRs to me
These PRs sometimes get lost as GH reduces their visibility, so I wanted to get an assignment so I can help these PRs land
setup typos check in CI
This allows to check typos in CI, currently for compiler only (to reduce commit size with fixes). With current setup, exclude list is quite short, so it worth trying?
Also includes commits with actual typo fixes.
MCP: https://github.com/rust-lang/compiler-team/issues/817
typos check currently turned for:
* ./compiler
* ./library
* ./src/bootstrap
* ./src/librustdoc
After merging, PRs which enables checks for other crates (tools) can be implemented too.
Found typos will **not break** other jobs immediately: (tests, building compiler for perf run). Job will be marked as red on completion in ~ 20 secs, so you will not forget to fix it whenever you want, before merging pr.
Check typos: `python x.py test tidy --extra-checks=spellcheck`
Apply typo fixes: `python x.py test tidy --extra-checks=spellcheck:fix` (in case if there only 1 suggestion of each typo)
Current fail in this pr is expected and shows how typo errors emitted. Commit with error will be removed after r+.
That branch is essentially the same as the `try` branch, it also needs S3 permissions.
Long term, we should move rollup unrolling from rustc-perf to bors, so that we can have only a single try branch.
