错误A2070: SSE MASM64中的指令操作数无效

Question

当在ml64.exe 64位(masm64)中编译时，SSE命令给我一个错误，我需要做什么才能在64位中包含SSE命令？

.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

我得到了错误：

1>Performing Custom Build Step
1> Assembling: extasm.asm
1>extasm.asm(6) : error A2070: invalid instruction operands
1>extasm.asm(10) : error A2070: invalid instruction operands
1>Microsoft (R) Macro Assembler (x64) Version 8.00.50727.215

1>Project : error PRJ0019: A tool returned an error code from "Performing Custom Build Step"

Answer 1

因此，将这两行修改为：

movlps QWORD PTRrdx，xmm7

移动dword ptr rdx+8，xmm6
