x86 intrinsics for rust
This crate implements C-like x86 intrinsics. The function and type names are
the same as what Intel uses (removing prefix underscore; e.g. __m128i -> m128i,
_mm_set_epi32 -> mm_set_epi32).
I actually need various integer SIMD arithmetics, so such functions will be implemeneted with priority.
Currently most of SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AVX, and AVX2 are implemented. Some of the functions cannot be implemented since rust is not exposing necessary functions.
After all done, I'd like to contribute to rust libraries to support missing functions.
You need nightly channel, since this crate uses unstable features.
To build with cargo, you need to set target-cpu or target-feature in RUSTFLAGS.
For example:
$ RUSTFLAGS="-C target-cpu=native" cargo build
$ RUSTFLAGS="-C target-feature=+sse3" cargo build
