-<h5>Overview:</h5>
-
-<p>
-The '<tt>llvm.isunordered</tt>' intrinsics return true if either or both of the
-specified floating point values is a NAN.

-
-<h5>Arguments:</h5>
-
-<p>
-The arguments are floating point numbers of the same type.
-</p>
-
-<h5>Semantics:</h5>
-
-<p>
-If either or both of the arguments is a SNAN or QNAN, it returns true, otherwise
-false.
