Feature gate: #![feature(portable_simd)]

This is a tracking issue for the future feature chartered in RFC 2977, with the intent of creating something akin to the design in RFC 2948 (rust-lang/rfcs#2948): a portable SIMD library (std::simd).

Portable SIMD project group: https://github.com/rust-lang/project-portable-simd
Implementation: https://github.com/rust-lang/portable-simd

More discussion can be found in the #project-portable-simd zulip stream.

Steps

Unresolved Questions

  • What will the overall design be?
    What are the ideal semantics for Masks?
    Are there any limits or vector sizes we should not support?
    How should these types interop with types like Saturating, NonZero, etc.?
