title: How to move 128-bit immediates to XMM registers
body: <p>There already is <a href="https://stackoverflow.com/questions/4609677/implementation-of-aes-in-assembly">a question</a> 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.</p>
  
  <p>The question is: how do you write a sequence of assembly code to initialize an XMM register with a 128-bit immediate (constant) value?</p>
