title: Function parameters transferred in registers on 64bit OS?
body: <p>I am reading one of Agner Fog's manuals and as an advantage for 64 bit Operating Systems (over 32 bit) he says:</p>
  
  <blockquote>
    <p>Function parameters are transferred in registers rather than on the
    stack. This makes function calls more efficient.</p>
  </blockquote>
  
  <p>Is he saying the stack is not used for passing function parameters (64bit OS) at all???</p>
