⚠️ Warning ⚠️

Some commits in this PR modify submodules.

If this was not intentional, see I changed a submodule on accident in the rustc dev guide.

dianqk · 2026-05-20T06:30:34Z

I made a new branch that dropped all reverts because llvm/llvm-project#194586 fixed the compile-time regressions.

Thanks!

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.
