Erro A2070: Operando de instrução inválida no SSE MASM64

Question

Ao compilar isso em ML64.exe 64bit (MASM64) O comando SSE me dá um erro O que preciso fazer para incluir os comandos SSE em 64 bits?

.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

Eu recebo o erro:

Answer 1

Portanto, modifique as duas linhas para:

movlps qword ptr [rdx], xmm7

movss dword ptr [rdx+8], xmm6
