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.

Current Status

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.

Note

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

x86intrin's Issues

question about mm_shuffle_ps

Hi,

I've got a small problem with mm_shuffle_ps.
When I run the example shuffle.rs, whatever value i use for the control, I never get any value from the second vector.
mm_shuffle_ps seems to always use only one vector.
Maybe I've misunderstood something, but it seems shufps can shuffle the two vectors.

I used last nightly.

_MM_SET_DENORMALS_ZERO_MODE

I noticed this crate provides _MM_SET_FLUSH_ZERO_MODE() but not _MM_SET_DENORMALS_ZERO_MODE().
Is is possible to provide _MM_SET_DENORMALS_ZERO_MODE(), too?

Check test coverage?

Issue #4 suggests me to check if test really covers all functions.
