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.
