Struct faiss::simd256bit

struct simd256bit

256-bit representation without interpretation as a vector

Simple wrapper around the AVX 256-bit registers

The objective is to separate the different interpretations of the same registers (as a vector of uint8, uint16 or uint32), to provide printing functions, and to give more readable names to the AVX intrinsics. It does not pretend to be exhausitve, functions are added as needed.
