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

unaligned types. * Add support for specifying the alignment to use. * Add the concept of native endianness. Used for unaligned native types. The native alignment and read/write simplification is based on a patch by Richard Smith. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171406 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
2013-01-02Update the examples for the new header file locations.Chandler Carruth
Sorry for the fallout here, I forgot the examples aren't built by default any more. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171371 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
2013-01-02Update the root Makefile for VMCore -> IR. Missed by my original searchChandler Carruth
sadly, and is somewhat surprising in general. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171361 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

2012-12-31Make it explicit that the only entry points to the Program object areChandler Carruth
through the static helper functions. This is already true throughout the codebase. Slowly, I'm going to re-implement these static helpers in terms of a new process based interface which can expose more information, and remove the program object entirely. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171335 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-31Flesh out a page size accessor in the new API.Chandler Carruth
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171330 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-31Remove the declspecs from small alignments that we can force withChandler Carruth
a union. These don't actually work for by-value function arguments, and MSVC warns if they exist even while (we hope) it aligns the argument correctly due to the other union member. This means MSVC will miss out on optimizations based on the alignment of the buffer, but really, there aren't that many for x86 and MSVC is likely not doing a great job of optimizing LLVM and Clang anyways. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171328 91177308-0d34-0410-b5e6-96231b3b80d8
