stdarch - Rust's standard library SIMD components
=======
[![Actions Status](https://github.com/rust-lang/stdarch/workflows/CI/badge.svg)](https://github.com/rust-lang/stdarch/actions)
# Crates
This repository contains two main crates:
* [![core_arch_crate_badge]][core_arch_crate_link]
[![core_arch_docs_badge]][core_arch_docs_link]
[`core_arch`](crates/core_arch/README.md) implements `core::arch` - Rust's
core library architecture-specific intrinsics, and
* [![std_detect_crate_badge]][std_detect_crate_link]
[![std_detect_docs_badge]][std_detect_docs_link]
[`std_detect`](crates/std_detect/README.md) implements `std::detect` - Rust's
standard library run-time CPU feature detection.
The `std::simd` component now lives in the
[`packed_simd`](https://github.com/rust-lang-nursery/packed_simd) crate.
# How to do a release
To do a release of the `core_arch` and `std_detect` crates,
* bump up the version appropriately,
* comment out the `dev-dependencies` in their `Cargo.toml` files (due to
https://github.com/rust-lang/cargo/issues/4242),
* publish the crates.
