Deep flatten is an optimization pass for the <a href="SSA2">SSA2</a> <a href="IntermediateLanguage">IntermediateLanguage</a>, invoked from <a href="SSA2Simplify">SSA2Simplify</a>. <h2 id="head-55f8ebc805e65b5b71ddafdae390e3be2bcd69af">Description</h2>
<p>
This pass flattens into mutable fields of objects and into vectors. 
</p>
<p>
For example, an <tt>(int&nbsp;*&nbsp;int)&nbsp;ref</tt> is represented by a 2 word object, and an <tt>(int&nbsp;*&nbsp;int)&nbsp;array</tt> contains pairs of <tt>int</tt>s, rather than pointers to pairs of <tt>int</tt>s.
