+<h5>Overview:</h5>
+
+<p>
+The '<tt>llvm.powi.*</tt>' intrinsics return the first operand raised to the

+multiplications is not defined.
+</p>
+
+<h5>Arguments:</h5>
+
+<p>
+The second argument is an integer power, and the first is a value to raise to
+that power.
+</p>
+
+<h5>Semantics:</h5>
+
+<p>
+This function returns the first value raised to the second power with an
+unspecified sequence of rounding operations.</p>
