SSE instructions also use the xmm registers! The problem wasn't in using the xmm registers (frankly, I hope it will accelerate things a bit by using the SSE to copy), but problem was, that those "f3 0f 7e ..." and "66 0f d6 ..." instructions (that's why I listed it with objdump) belong to the to the SSE2 instruction set. If instead it would use the instructions from SSE only (also with xmm regs. of course), that would be good. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19235
