如何将128位的立即到XMM寄存器 [英] How to move 128-bit immediates to XMM registers

问题描述

有已经是对这个问题，但它被关闭的暧昧所以我打开一个新 - 我已经找到了答案，也许这将帮助别人太

There already is a question on this, but it was closed as "ambiguous" so I'm opening a new one - I've found the answer, maybe it will help others too.

现在的问题是：你如何编写汇编code的顺序，有128位立即（常数）值来初始化XMM寄存器

The question is: how do you write a sequence of assembly code to initialize an XMM register with a 128-bit immediate (constant) value?

推荐答案

只是想补充一点，人们可以读到关于瓦格纳雾手册的汇编语言优化子程序，生成常量，第13.4节，第121页。

Just wanted to add that one can read about generating various constants using assembly in Agner Fog's manual Optimizing subroutines in assembly language, Generating constants, section 13.4, page 121.
