sergey-sj commented 7 years ago

movq mm0,[eax]; 0F 6F 00 ; ok movq [eax],mm0; 0F 7E 00 ; wrong (it's movd, not movq), should be 0F 7F 00
movd mm0,[eax]; 0F 6E 00 ; ok movd [eax],mm0; 0F 7E 00 ; ok movd xmm0,[eax]; 66 0F 6E 00; ok movd [eax],xmm0; 66 0F 7E 00; ok movq xmm0,[eax]; F3 0F 7E 00; ok movq [eax],mm0; 66 0F D6 00; ok
