// 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() ...
//
// 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
// has state or virtual methods, which is an important part of this gross/neat
// hack working.
//
// In some cases, arguments to intrinsics need to be generic and are defined as
// type pointer to empty struct { }*. To access the real item of interest the
// cast instruction needs to be stripped away.
