segmentation fault was caused when aligned and unaligned versions were
called concurrently.

Carles Fernandez d8b45d9b79 fix wrong storeu by store 2016-03-28 13:51:51 +02:00
Carles Fernandez 78372ba2e9 adding _mm256_zeroupper() at the end of AVX and AVX2 protokernels 
This avoids penalties for state transitions from 256-bit x86-AVX
instructions to x86-SSE instructions

unaligned) and NEON protokernels.

Carles Fernandez 751764343c adding AVX2 protokerns 
I haven't found a way to do the rotator part better than with SSE3. Only
the dot product takes real advantage of 256-bit registers. Even tough,
the gain with respect to SSE3 is about 12%.
