Hey! It looks like you've submitted a new PR for the library teams!

If this PR contains changes to any rust-lang/rust public library APIs then please comment with @rustbot label +T-libs-api -T-libs to tag it appropriately. If this PR contains changes to any unstable APIs please edit the PR description to add a link to the relevant API Change Proposal or create one if you haven't already. If you're unsure where your change falls no worries, just leave it as is and the reviewer will take a look and make a decision to forward on if necessary.

Examples of T-libs-api changes:

• Stabilizing library features
• Introducing insta-stable changes such as new implementations of existing stable traits on existing stable types
• Introducing new or changing existing unstable library APIs (excluding permanently unstable features / features without a tracking issue)
• Changing public documentation in ways that create new stability guarantees
• Changing observable runtime behavior of library APIs

cc @calebzulawski Any idea why this is failing? I would have thought your PR #103750 makes this work.

[calebzulawski]

It looks like std is built with the beta compiler, which doesn't have those changes yet

[Amanieu]

The beta compiler should have been updated just last week though, so I would expect it to include these changes.

[calebzulawski]

The log shows downloading the beta compiler from Nov 1, that sounds like 1.66 rather than 1.67

[Amanieu]

Blocked on #105741.

[Amanieu]

#105741 is now merged, can you rebase?

[yanns]

@Amanieu Do you have an idea why it is failing? Can I help somehow?

[calebzulawski]

Those errors are due to changes from #100752. Some feature names have been deprecated in the is_x86_feature_detected macro. I added allow(deprecated) to the tests that use the old names, though...

[calebzulawski]

Ah actually, as part of this update, this file needs to change too:

rust/library/std/tests/run-time-detect.rs

Line 123 in c757267

println!("avx512gfni: {:?}", is_x86_feature_detected!("avx512gfni"));

rust/library/std/tests/run-time-detect.rs

Line 126 in c757267

println!("avx512vaes: {:?}", is_x86_feature_detected!("avx512vaes"));

rust/library/std/tests/run-time-detect.rs

Line 132 in c757267

println!("avx512vpclmulqdq: {:?}", is_x86_feature_detected!("avx512vpclmulqdq"));

avx512gfni, avx512vaes, and avx512vpclmulqdq should all have the avx512 prefix removed.

@calebzulawski thanks for the help. The CI checks are passing now.
