errore A2070: operandi un'istruzione non valida nel SSE MASM64

Question

Nella compilazione di questa in ml64.exe 64bit (masm64) il comando SSE mi danno un errore Che cosa devo fare per includere i comandi SSE a 64 bit?

.code

foo PROC

  movlps [rdx], xmm7 ;;error A2070: invalid instruction operands
  movhlps xmm6, xmm7
  movss [rdx+8], xmm6 ;;rror A2070: invalid instruction operands
  ret

foo ENDP

end

ottengo l'errore:

Answer 1

Quindi modificare le due righe:

movlps QWORD PTR [RDX], xmm7

movss dword ptr [RDX + 8], xmm6
