I'm thinking of implementation std.simd in fashion different to https://github.com/TurkeyMan/simd since it looks dead and too sophisticated. My proposal is: - std.simd - processor independent intrinsics and some high level stuff. You only depend on different sizes of SIMD vector. - std.simd.x86 - provides unified (compiler independent) x86/x86_64 intrinsic call. Each SIMD version (sse, sse2, ...) has its own namespace(struct) with intrinsic wrappers. Each wrapper is straightforward. - std.simd.arm - provides unified arm-based SIMD. Demo: https://github.com/Iakh/simd At the end of the file https://github.com/Iakh/simd/blob/master/std/simd/x86.d is a long unittest with sse2 memchar implementation.
