// This file defines classes 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 (MemCpyInst *MCI = dyn_cast<MemCpyInst>(Inst))
|
|
// ... MCI->getDest() ... MCI->getSource() ...
|
|
//
|
|
// 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.
