* [opt][PassInfo] Allow opt to run passes that need target machine.Quentin Colombet2014-01-161-0/+2
| | | | | | | | | | | | | | | | | | When registering a pass, a pass can now specify a second construct that takes as argument a pointer to TargetMachine. The PassInfo class has been updated to reflect that possibility. If such a constructor exists opt will use it instead of the default constructor when instantiating the pass. Since such IR passes are supposed to be rare, no specific support has been added to this commit to allow an easy registration of such a pass. In other words, for such pass, the initialization function has to be hand-written (see CodeGenPrepare for instance). Now, codegenprepare can be tested using opt: opt -codegenprepare -mtriple=mytriple input.ll llvm-svn: 199430
* Use an RWMutex instead of a Mutex in PassRegistry.Chad Rosier2013-07-031-10/+11

* 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
* Rename VMCore directory to IR.Chandler Carruth2013-01-021-0/+209
Aside from moving the actual files, this patch only updates the build system and the source file comments under lib/... that are relevant. I'll be updating other docs and other files in smaller subsequnet commits. While I've tried to test this, but it is entirely possible that there will still be some build system fallout. Also, note that I've not changed the library name itself: libLLVMCore.a is still the library name. I'd be interested in others' opinions about whether we should rename this as well (I think we should, just not sure what it might break) llvm-svn: 171359
