ToSSA2 is a translation pass from the <a href="SSA">SSA</a> <a href="IntermediateLanguage">IntermediateLanguage</a> to the <a href="SSA2">SSA2</a> <a href="IntermediateLanguage">IntermediateLanguage</a>. <h2 id="head-55f8ebc805e65b5b71ddafdae390e3be2bcd69af">Description</h2>
<p>
This pass is a simple conversion from a <a href="SSA">SSA</a> program into a <a href="SSA2">SSA2</a> program.
</p>
<p>
The only interesting portions of the translation are:
</p>
<ul>
<li>
<p>
an <a href="SSA">SSA</a> <tt>ref</tt> type becomes an object with a single mutable field
</p>
</li>
<li class="gap">
<p>
<tt>array</tt>, <tt>vector</tt>, and <tt>ref</tt> are eliminated in favor of select and updates
</p>
</li>
<li class="gap">
<p>
<tt>Case</tt> transfers separate discrimination and constructor argument selects
</p>
</li>
</ul>
