title: What are the names of the new X86_64 processors registers?
body: <p>Where can I find the names of the new registers for assembly on this architecture?</p>
  
  <p>I am referring to registers in X86 like EAX, ESP, EBX, etc. But I'd like them in 64bit.</p>
  
  <p>I don't think they are the same as when I disassemble my C code, I get r's instead of e's.  </p>
