Nonetheless some final remarks from my side: * It removes the existing SSE2 code path. Most likely not that much of an issue due to the new AVX variant. * I certainly would favor gradual improvement, and I think the code would allow it. But as said, not my pick. * Those 4000+ lines perl/asm are a lot and a hard review; I won't find time and motivation to do it. ;-) Thanks! Martin
