<h5>Syntax:</h5>
<pre>
declare &lt;float or double&gt; %llvm.sqrt(&lt;float or double&gt; 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.
