+<h5>Syntax:</h5>
+<pre>
+  declare <float or double> %llvm.sqrt(<float or double> Val)
+</pre>
+
+<h5>Overview:</h5>
+
+<p>
+The '<tt>llvm.sqrt</tt>' intrinsic returns the sqrt of the specified operand,
+returning the same value as the libm '<tt>sqrt</tt>' function would.  Unlike
+<tt>sqrt</tt> in libm, however, <tt>llvm.sqrt</tt> has undefined behavior for
+negative numbers (which allows for better optimization).
+</p>
+
+<h5>Arguments:</h5>
+
+<p>
+The argument and return value are floating point numbers of the same type.
+</p>
+
+<h5>Semantics:</h5>
+
+<p>
+This function returns the sqrt of the specified operand if it is a positive
+floating point number.
+</p>
