into their new header subdirectory: include/llvm/IR. This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM. There are still more header files to move here, but I wanted to handle them in separate commits to make tracking what files make sense at each layer easier. The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today. I've updated both CMake and Makefile build systems (I think, and my tests think, but I may have missed something). I've also re-sorted the includes throughout the project. I'll be committing updates to Clang, DragonEgg, and Polly momentarily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171366 91177308-0d34-0410-b5e6-96231b3b80d8

|
|
// 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.
