+<h5>Overview:</h5>
+<p>The '<tt>llvm.exp.*</tt>' intrinsics perform the exp function.</p>

+<h5>Arguments:</h5>
+<p>The argument and return value are floating point numbers of the same

+
+<h5>Semantics:</h5>
+<p>This function returns the same values as the libm <tt>exp</tt> functions
+   would, and handles error conditions in the same way.</p>
