- FEAT_SME_F16F16
- FEAT_SME_F64F64
- FEAT_SME_F8F16
- FEAT_SME_F8F32
- FEAT_SME_FA64
- FEAT_SME_I16I64
- FEAT_SME_LUTv2
- FEAT_SME2
- FEAT_SME2p1
- FEAT_SSVE_FP8DOT2
- FEAT_SSVE_FP8DOT4
- FEAT_SSVE_FP8FMA

stdarch - Rust's standard library SIMD components

Actions Status

Crates

This repository contains two main crates:

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

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

The std::simd component now lives in the packed_simd_2 crate.
