 // This file implements methods that make it really easy to deal with intrinsic
-// functions with the isa/dyncast family of functions.  In particular, this
-// allows you to do things like:
-//
-//     if (DbgStopPointInst *SPI = dyn_cast<DbgStopPointInst>(Inst))
-//        ... SPI->getFileName() ... SPI->getDirectory() ...
+// functions.
 //
 // All intrinsic function calls are instances of the call instruction, so these
 // are all subclasses of the CallInst class.  Note that none of these classes
