<a name="sretpromotion">-sretpromotion: Promote sret arguments to multiple ret values</a>
</h3>
<div>
<p>
This pass finds functions that return a struct (using a pointer to the struct
as the first argument of the function, marked with the '<tt>sret</tt>' attribute) and
replaces them with a new function that simply returns each of the elements of
that struct (using multiple return values).
</p>
<p>
This pass works under a number of conditions:
</p>
<ul>
<li>The returned struct must not contain other structs</li>
<li>The returned struct must only be used to load values from</li>
<li>The placeholder struct passed in is the result of an <tt>alloca</tt></li>
</ul>
