// 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
