Subject: AVX bitsliced sha256


Just test bitsliced sha256 with floating point AVX boolean (256 bits registers). In a core i3-2120 is 20% slower than bitsliced SSE2 (128 bits registers with integer boolean). Giving a look at instructions throughput SSE2 is 50% faster per bit than AVX (3 instructions each cycle for SSE2 vs only 1 for AVX).
