re-stabilize the AVX-512 features that were stabilized in Rust 1.27.0 (#842) 
* re-stabilize the AVX-512 features that were stabilized in Rust 1.27.0

https://github.com/rust-lang/stdarch/pull/739 added per-feature
stabilization of runtime CPU feature detection. In so doing, it
de-stabilized some detection features that had been stable since Rust
1.27.0, breaking some published crates (on nightly). This commit
re-stabilizes the subset of AVX-512 detection features that were
included in 1.27.0 (that is, the pre-Ice-Lake subset). Other instruction
sets (MMX in particular) remain de-stabilized, pending a decision about
whether should ever stabilize them.

See https://github.com/rust-lang/rust/issues/68905.

* add a comment explaining feature detection stability

* adjust stabilizations to match most recent proposal

stdarch - Rust's standard library SIMD components

Actions Status

Crates

This repository contains two main crates:

  • core_arch_crate_badge core_arch_docs_badge core_arch implements core::arch - Rust's core library architecture-specific intrinsics, and

  • std_detect_crate_badge std_detect_docs_badge std_detect implements std::detect - Rust's standard library run-time CPU feature detection.

The std::simd component now lives in the packed_simd crate.

How to do a release

To do a release of the core_arch and std_detect crates,
