本文介绍了如何将浮点常量值移动到 xmm 寄存器中?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
是将值移动到 xmm 寄存器的唯一方法，首先将值移动到整数寄存器，不知道它们叫什么，然后再移动到 xmm 寄存器，例如
Is the only way to move a value into an xmm register by first moving the value into an integer register, dunno what they are called, and then into the xmm register e.g.
mov [eax], (float)1000 ; store to memory
movss xmm1,[eax] ; reload
或
mov eax, 1000 ; move-immediate integer
cvtsi2ss xmm1,eax ; and convert
或者有其他方法吗?有没有办法直接将值移动到 xmm 寄存器中，类似于:movss xmm1,(float)1000?
or is there another way? Is there a way to directly move a value into a xmm register, something along the lines of: movss xmm1,(float)1000?
推荐答案
没有使用立即数加载 SSE 寄存器的说明.常见的习惯用法是从全局常量加载您需要的值:
There are no instructions to load an SSE register with an immediate. The common idiom is to load the value you need from a global constant:
const dd 1000.0
...
movss xmm0,[const]
