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

|
|
// single entry, multiple exit, region of code that is often hot. Trace-based
|
|
// optimizations treat traces almost like they are a large, strange, basic
|
|
// block: because the trace path is assumed to be hot, optimizations for the
|
|
// fall-through path are made at the expense of the non-fall-through paths.
