<h5>Syntax:</h5>
<pre>
declare void @llvm.var.annotation(i8* &lt;val&gt;, i8* &lt;str&gt;)
</pre>
<h5>Overview:</h5>
<p>
The '<tt>llvm.var.annotation</tt>' intrinsic
</p>
<h5>Arguments:</h5>
<p>
The first argument is a pointer to a value, and the second is a pointer to a
global string.
</p>
<h5>Semantics:</h5>
<p>
This intrinsic allows annotation of local variables with arbitrary strings.
This can be useful for special purpose optimizations that want to look for these
annotations. These have no other defined use, they are ignored by code
generation and optimization.
