1. Fix the macros in IncludeFile.h to put everything in the llvm namespace 2. Replace the previous explicit mechanism in all the .h and .cpp files with the macros in IncludeFile.h This gets us a consistent mechanism throughout LLVM for ensuring linkage. Next step is to make sure its used in enough places. llvm-svn: 28715

// 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.
