The optimization passes for the <a href="SSA2">SSA2</a> <a href="IntermediateLanguage">IntermediateLanguage</a> are collected and controlled by the <tt>Simplify2</tt> functor (<a href = "http://mlton.org/cgi-bin/viewsvn.cgi/mlton/tags/on-MLTONWIKIVERSION-release/mlton/ssa/simplify2.sig?view=markup"><img src="moin-www.png" alt="[WWW]" height="11" width="11">simplify2.sig</a>,<a href = "http://mlton.org/cgi-bin/viewsvn.cgi/mlton/tags/on-MLTONWIKIVERSION-release/mlton/ssa/simplify2.fun?view=markup"><img src="moin-www.png" alt="[WWW]" height="11" width="11">simplify2.fun</a>).   <p>
The following optimization passes are implemented: 
</p>

    <ul>

    <li>
<p>
 <a href="DeepFlatten">DeepFlatten</a> 
</p>
</li>
    <li>
<p>
 <a href="RefFlatten">RefFlatten</a> 
</p>
</li>
    <li>
<p>
 <a href="RemoveUnused">RemoveUnused</a> 
</p>
</li>
    <li>
<p>
 <a href="Zone">Zone</a> 
</p>
</li>

    </ul>


<p>
There are additional analysis and rewrite passes that augment many of the other optimization passes: 
</p>

    <ul>

    <li>
<p>
 <a href="Restore">Restore</a> 
</p>
</li>
    <li>
<p>
 <a href="Shrink">Shrink</a> 
</p>
</li>

    </ul>


<p>
The optimization passes can be controlled from the command-line by the options 
</p>

    <ul>

    <li>
<p>
 <tt>diag-pass&nbsp;&lt;pass&gt;</tt> -- keep diagnostic info for pass 
</p>
</li>
    <li>
<p>
 <tt>drop-pass&nbsp;&lt;pass&gt;</tt> -- omit optimization pass 
</p>
</li>
    <li>
<p>
 <tt>keep-pass&nbsp;&lt;pass&gt;</tt> -- keep the results of pass 
</p>
</li>
    <li>
<p>
 <tt>loop-passes&nbsp;&lt;n&gt;</tt> -- loop optimization passes 
</p>
</li>
    <li>
<p>
 <tt>ssa2-passes&nbsp;&lt;passes&gt;</tt> -- ssa optimization passes 
</p>
</li>
</ul>
