* Move all of the header files which are involved in modelling the LLVM IRChandler Carruth2013-01-021-1/+1
| | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 171366

* R600: New control flow for SI v2Tom Stellard2012-12-191-0/+732
This patch replaces the control flow handling with a new pass which structurize the graph before transforming it to machine instruction. This has a couple of different advantages and currently fixes 20 piglit tests without a single regression. It is now a general purpose transformation that could be not only be used for SI/R6xx, but also for other hardware implementations that use a form of structurized control flow. v2: further cleanup, fixes and documentation Patch by: Christian König Signed-off-by: Christian König <deathsimple@vodafone.de> Reviewed-by: Tom Stellard <thomas.stellard@amd.com> Tested-by: Michel Dänzer <michel.daenzer@amd.com> llvm-svn: 170591
