2013-01-03Remove the 'contains' methods in favor of the 'operator==' method.Bill Wendling
The 'operator==' method is a bit clearer and much less verbose for somethings that should have only one value. Remove from the AttrBuilder for consistency. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171442 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-03Fix PR14732 by handling all kinds of IMPLICIT_DEF live ranges.Jakob Stoklund Olesen
Most IMPLICIT_DEF instructions are removed by the ProcessImplicitDefs pass, and a few are reinserted by PHIElimination when a PHI argument is <undef>. RegisterCoalescer was assuming that all IMPLICIT_DEF live ranges look like those created by PHIElimination, and that their live range never leaves the basic block. The PR14732 test case does tricks with PHI nodes that causes a longer IMPLICIT_DEF live range to appear. This happens very rarely, but RegisterCoalescer should be able to handle it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171435 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-02Extend the dumping infrastructure to deal with additionalEric Christopher
sections for debug info. These are some of the dwo sections from the DWARF5 split debug info proposal. Update the fission-cu.ll testcase to show what we should be able to dump more of now. Work in progress: Ultimately the relocations will be gone for the dwo section and the strings will be a different form (as well as the rest of the sections will be included). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171428 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-02An intermediate step in the Attributes rewrite.Bill Wendling
Modify the AttrBuilder class to store the attributes as a set instead of as a bit mask. The Attribute class will represent only one attribute instead of a collection of attributes. This is the wave of the future! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171427 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-02DAGCombiner: Avoid generating illegal vector INT_TO_FP nodesTom Stellard
DAGCombiner::reduceBuildVecConvertToConvertBuildVec() was making two mistakes: 1. It was checking the legality of scalar INT_TO_FP nodes and then generating vector nodes. 2. It was passing the result value type to TargetLoweringInfo::getOperationAction() when it should have been passing the value type of the first operand. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171420 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-02Actually update the CMake and Makefile builds correctly, and update theChandler Carruth
code that includes Intrinsics.gen directly. 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
2013-01-02Move all of the header files which are involved in modelling the LLVM IRChandler Carruth
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
2013-01-02Resort the #include lines in include/... and lib/... with theChandler Carruth
utils/sort_includes.py script. Most of these are updating the new R600 target and fixing up a few regressions that have creeped in since the last time I sorted the includes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171362 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-02Rename VMCore directory to IR.Chandler Carruth
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) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171359 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-01Added DEBUG message when ObjCARC replaces a call which returns its argument ↵Michael Gottesman
verbatim with its argument to temporarily undo an optimization. Specifically these calls return their argument verbatim, as a low-level optimization. However, this makes high-level optimizations harder. We undo any uses of this optimization that the front-end emitted. We redo them later in the contract pass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171346 91177308-0d34-0410-b5e6-96231b3b80d8
