This commit adds compiler support for two basic operations needed for binding SIMD on x86 platforms: * First, a `nontemporal_store` intrinsic was added for the `_mm_stream_ps`, seen in rust-lang-nursery/stdsimd#114. This was relatively straightforward and is quite similar to the volatile store intrinsic. * Next, and much more intrusively, a new type to the backend was added. The `x86_mmx` type is used in LLVM for a 64-bit vector register and is used in various intrinsics like `_mm_abs_pi8` as seen in rust-lang-nursery/stdsimd#74. This new type was added as a new layout option as well as having support added to the trans backend. The type is enabled with the `#[repr(x86_mmx)]` attribute which is intended to just be an implementation detail of SIMD in Rust. I'm not 100% certain about how the `x86_mmx` type was added, so any extra eyes or thoughts on that would be greatly appreciated! |
