| # Crates |
| |
| This repository contains two main crates: |
| |
| * [`core_arch`](crates/core_arch/README.md) implements `core::arch` - Rust's |
| core library architecture-specific intrinsics, and |
| |
| * [`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_2`](https://github.com/rust-lang/packed_simd) crate. |

| ## Synchronizing josh subtree with rustc |
| |
| This repository is linked to `rust-lang/rust` as a [josh](https://josh-project.github.io/josh/intro.html) subtree. You can use the [rustc-josh-sync](https://github.com/rust-lang/josh-sync) tool to perform synchronization. |
| |
| You can find a guide on how to perform the synchronization [here](https://rustc-dev-guide.rust-lang.org/external-repos.html#synchronizing-a-josh-subtree). |
