Matthew Krupcale d91f20dd29 Start SSE2 implementation based on SSE4.1 version ... Wire up basic functions and features for SSE2 support using the SSE4.1 version as a basis without implementing the SSE2 instructions yet. * Cargo.toml: add no_sse2 feature * benches/bench.rs: wire SSE2 benchmarks * build.rs: add SSE2 rust intrinsics and assembly builds * c/Makefile.testing: add SSE2 C and assembly targets * c/README.md: add SSE2 to C build instructions * c/blake3_c_rust_bindings/build.rs: add SSE2 C rust binding builds * c/blake3_c_rust_bindings/src/lib.rs: add SSE2 C rust bindings * c/blake3_dispatch.c: add SSE2 C dispatch * c/blake3_impl.h: add SSE2 C function prototypes * c/blake3_sse2.c: add SSE2 C intrinsic file starting with SSE4.1 version * c/blake3_sse2_x86-64_{unix.S,windows_gnu.S,windows_msvc.asm}: add SSE2 assembly files starting with SSE4.1 version * src/ffi_sse2.rs: add rust implementation using SSE2 C rust bindings * src/lib.rs: add SSE2 rust intrinsics and SSE2 C rust binding rust SSE2 module configurations * src/platform.rs: add SSE2 rust platform detection and dispatch * src/rust_sse2.rs: add SSE2 rust intrinsic file starting with SSE4.1 version * tools/instruction_set_support/src/main.rs: add SSE2 feature detection		2020-08-24 00:54:46 -04:00
