title: ASM 'sall' command with single argument?
body: <p>The sall instruction, in the form </p>
  
  <pre><code>sall  Src,Dest 
  </code></pre>
  
  <p>translates into a left shift of Dest by Src </p>
  
  <pre><code>Dest=Dest&lt;&lt;Src
  </code></pre>
  
  <p>But I have no idea what this is:</p>
  
  <pre><code>   sall    -8(%ebp)
  </code></pre>
  
  <p>I would presume that its shifting -8(%ebp) left, but by how much?</p>
