+
+<p>
+The '<tt>llvm.var.annotation</tt>' intrinsic
+</p>
+
+<h5>Arguments:</h5>
+
+<p>
+The first argument is a pointer to a value, the second is a pointer to a 
+global string, the third is a pointer to a global string which is the source 
+file name, and the last argument is the line number.
+</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.
