• widekl: Intel Key Locker Wide

Steps / History

• Add the target features to Rust
• Add the Intrinsics and Feature Detection to stdarch
• Final comment period (FCP)¹
• Update the Reference
  • Add doc for keylocker target features reference#1829
• Stabilization PR
  • Stabilize keylocker #140766
  • Stabilize keylocker intrinsics and runtime detection stdarch#1795

Unresolved Questions

• None yet.

Implementation History

• Add kl and widekl target features, and the feature gate #134814

I believe this is also ready for stabilization, as all the intrinsics have been implemented already.

We do our stabilization FCPs on stabilization PRs. Please submit and nominate one of those for us along with the stabilization report. See the new template for that:

rust-lang/rustc-dev-guide#2219

The lang-stabilization is being done in #140766, so let's do the libs stabilization here (intrinsics and runtime detection, in rust-lang/stdarch#1795)
