OK, so nothing new here, same 32-bytes alignment. > when "mulps m0, m1, [mem]" would work just as well regardless of alignment. It does with AVX?

OK. As you are the number one developer for AVX, it's up to you whether that would need a more generic fix :-) Someone actually used to AVX should comment, but this patch looks so simple that you should apply it tomorrow if nobody objects.
