Aren't xmm0 MMX registers which means they overlap with the floating point
registers in some cases and that also means you need to use emms instructions?

With this code:
#include <mmintrin.h>
__m64 f(__m64 x, __m64 y){return _mm_sub_pi32(x,y);}
I get (-m64):
movdq2q %xmm0, %mm0
movdq2q %xmm1, %mm1
psubd %mm1, %mm0
movq2dq %mm0, %xmm0
and (-m32):
psubd %mm1, %mm0

This is fixed in GCC 10+ with the patches do do 64bit vector support in SSE.
