SIMD Everywhere: 0.5.0
I sometimes write code portable across SSE4 and NEON, and I'm not sure this is going to work fast enough for that. There're important unique features.<p>SSE has shuffles, pack/unpack, movemask, 64-bit doubles, testzero, float rounds, blends, integer averages, float square roots and dot product.<p>NEON has interleaved RAM load/stores, vectors operators with scalar other argument, byte swap, rotate, bit scan and population count, and versions of all instructions processing 8-byte long vectors.<p>That's enough differences that I have to adjust both algorithms and data structures to be portable between them. I'm not convinced it's possible to do automatically.
