Maybe we can add this check to the portable SIMD repo to avoid this in the future... I can't fix the commits now in a subtree update.

The Miri subtree was changed

cc @rust-lang/miri

calebzulawski · 2026-01-29T01:02:19Z

@RalfJung I had to update the miri tests in the last commit to match std::simd. This is fine and will sync back to miri, right?

RalfJung · 2026-01-29T10:00:47Z

Yes, that'll be synced automatically after this PR lands. Thanks for the fixes!

folkertdev · 2026-01-29T11:27:05Z

I asked at #t-infra > PRs/issues mentioned in subtree sync just to check, and yeah there is not much we can do about the PR mentions now.

Fun fact: this caused a small perf win for doc builds. See the rollup PR (#151816) for measurements.

calebzulawski · 2026-01-30T04:31:52Z

Pleasant surprise! We removed a trait bound from nearly every function in the module, I wonder if that did it.
