* Make SimplifyCFG simply depend upon TargetTransformInfo and pass itChandler Carruth2013-01-072-46/+52
| | | | | | | | | | | | | through as a reference rather than a pointer. There is always *some* implementation of this available, so this simplifies code by not having to test for whether it is available or not. Further, it turns out there were piles of places where SimplifyCFG was recursing and not passing down either TD or TTI. These are fixed to be more pedantically consistent even though I don't have any particular cases where it would matter. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171691 91177308-0d34-0410-b5e6-96231b3b80d8

This helper relies on TargetLowering information that shouldn't be generally used throughout the Transfoms library, and so it made little sense as a generic utility.

This never showed up in my testing because the old Intrinsics.gen was still kicking around in the make build system and was correct there. =[ Thankfully, some of the bots to clean rebuilds and that caught this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171373 91177308-0d34-0410-b5e6-96231b3b80d8
* Move all of the header files which are involved in modelling the LLVM IRChandler Carruth2013-01-02110-468/+468
| | | | | | | | | | | | | | | | | | | | | 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
