* LoopVectorizer: Add support for loop-unrolling during vectorization for ↵Nadav Rotem2013-01-032-169/+329
| | | | | | increasing the ILP. At the moment this feature is disabled by default and this commit should not cause any functional changes. llvm-svn: 171436
* Fix PR14732 by handling all kinds of IMPLICIT_DEF live ranges.Jakob Stoklund Olesen2013-01-031-8/+37
| | | | | | | | | | | | | | | | 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. llvm-svn: 171435
* Make the type signature more strict.Bill Wendling2013-01-032-4/+4

* Extend the dumping infrastructure to deal with additionalEric Christopher2013-01-026-29/+148
| | | | | | | | | | | | 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). llvm-svn: 171428
* An intermediate step in the Attributes rewrite.Bill Wendling2013-01-021-1/+20
| | | | | | | | | | 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! llvm-svn: 171427
* DAGCombiner: Avoid generating illegal vector INT_TO_FP nodesTom Stellard2013-01-021-4/+5
| | | | | | | | | | | | | | 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. llvm-svn: 171420

* Actually update the CMake and Makefile builds correctly, and update theChandler Carruth2013-01-024-9/+9
| | | | | | | | | | 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. llvm-svn: 171373
* Move all of the header files which are involved in modelling the LLVM IRChandler Carruth2013-01-02446-1462/+1462
| | | | | | | | | | | | | | | | | | | | | 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
* Resort the #include lines in include/... and lib/... with theChandler Carruth2013-01-0235-45/+35
| | | | | | | | | | 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. llvm-svn: 171362
* Rename VMCore directory to IR.Chandler Carruth2013-01-0252-24/+24
| | | | | | | | | | | | | | | | | | 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

* Added DEBUG message when ObjCARC replaces a call which returns its argument ↵Michael Gottesman2013-01-011-2/+6
| | | | | | | | | | | 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. llvm-svn: 171346
* Added DEBUG messages to the top of several processing loops in ObjCARC.cpp ↵Michael Gottesman2013-01-011-3/+32
| | | | | | | | | that emit what instructions are being visited. This is a part of a larger effort of adding DEBUG messages to the ARC Optimizer Backend. llvm-svn: 171345

* Remove an unused method on Program.Chandler Carruth2012-12-312-35/+0
| | | | | | | I'm simplifying this interface as much as I can before merging it with the new process interface. llvm-svn: 171334

* Go ahead and get rid of the old page size interface and convert all theChandler Carruth2012-12-314-19/+11

* Flesh out a page size accessor in the new API.Chandler Carruth2012-12-313-12/+21
| | | | | | | | Implement the old API in terms of the new one. This simplifies the implementation on Windows which can now re-use the self_process's once initialization. llvm-svn: 171330

| | | | | | | The new code is an improved copy of the code I deleted from Analysis/Loads.cpp. One less compute-constant-gep-offset implementation. yay :) llvm-svn: 171326

* Switch this code to a more idiomatic double using namespace directive.Chandler Carruth2012-12-313-6/+3
| | | | | | | | Fix a truly odd namespace qualifier that was flat out wrong in the process. The fully qualified namespace would have been llvm::sys::TimeValue, llvm::TimeValue makes no sense. llvm-svn: 171292

* Begin sketching out the process interface.Chandler Carruth2012-12-313-1/+33
| | | | | | | | | | | | | | | | | | | | | | | The coding style used here is not LLVM's style because this is modeled after a Boost interface and thus done in the style of a candidate C++ standard library interface. I'll probably end up proposing it as a standard C++ library if it proves to be reasonably portable and useful. This is just the most basic parts of the interface -- getting the process ID out of it. However, it helps sketch out some of the boiler plate such as the base class, derived class, shared code, and static factory function. It also introduces a unittest so that I can incrementally ensure this stuff works. However, I've not even compiled this code for Windows yet. I'll try to fix any Windows fallout from the bots, and if I can't fix it I'll revert and get someone on Windows to help out. There isn't a lot more that is mandatory, so soon I'll switch to just stubbing out the Windows side and get Michael Spencer to help with implementation as he can test it directly. llvm-svn: 171289
