`core::arch` - Rust's core library architecture-specific intrinsics
=======
The `core::arch` module implements architecture-dependent intrinsics (e.g. SIMD).
# Usage
`core::arch` is available as part of `libcore` and it is re-exported by
`libstd`. Prefer using it via `core::arch` or `std::arch` than via this crate.
Unstable features are often available in nightly Rust via the
`feature(stdsimd)`.
Using `core::arch` via this crate requires nightly Rust, and it can (and does)
break often. The only cases in which you should consider using it via this crate
are:
* if you need to re-compile `core::arch` yourself, e.g., with particular
target-features enabled that are not enabled for `libcore`/`libstd`. Note: if
you need to re-compile it for a non-standard target, please prefer using
`xargo` and re-compiling `libcore`/`libstd` as appropriate instead of using
this crate.
* using some features that might not be available even behind unstable Rust
features. We try to keep these to a minimum. If you need to use some of these
features, please open an issue so that we can expose them in nightly Rust and
you can use them from there.
