2013-01-05Switch SimplifyCFG over to the TargetTransformInfo interface rather thanChandler Carruth
the ScalarTargetTransformInfo interface. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171617 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-05Switch LoopIdiomRecognize to directly use the TargetTransformInfoChandler Carruth
interface rather than the ScalarTargetTransformInterface. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171616 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-05Sink the AddressingModeMatcher helper class into an anonymous namespaceChandler Carruth
next to its only user. This helper relies on TargetLowering information that shouldn't be generally used throughout the Transfoms library, and so it made little sense as a generic utility. This also consolidates the file where we need to remove the remaining uses of TargetLowering in favor of the IR-layer abstract interface in TargetTransformInfo. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171590 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-05iLoopVectorize: Non commutative operators can be used as reduction variables ↵Nadav Rotem

2013-01-04Do not vectorize loops with subtraction reductionsPaul Redmond
Since subtraction does not commute the loop vectorizer incorrectly vectorizes reductions such as x = A[i] - x. Disabling for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171537 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-04Added DEBUG message to ObjCARC when we optimize objc_retain => ↵Michael Gottesman

2013-01-04Fixed up some DEBUG messages where I was putting in the text of a message ↵Michael Gottesman
the method where it was being called when I should have just prefixed the actual message with Pass::Method. Additionally I fixed some whitespace issues. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171534 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-04Move the loop vectorizer from O2 to O3. It looks like the increase in code ↵Nadav Rotem
size actually hurts the performance on many programs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171471 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-03Added DEBUG message for ObjCARC when an inline asm marker is inserted for ↵Michael Gottesman
architectures where this is required to perform a retainAutoreleasedReturnValue optimization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171462 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-03LoopVectorizer: Add support for loop-unrolling during vectorization for ↵Nadav Rotem
increasing the ILP. At the moment this feature is disabled by default and this commit should not cause any functional changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171436 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

2013-01-01Added 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
2013-01-01Added DEBUG messages to the top of several processing loops in ObjCARC.cpp ↵Michael Gottesman
that emit what instructions are being visited. This is a part of a larger effort of adding DEBUG messages to the ARC Optimizer Backend. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171345 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-30convert a bunch of callers from DataLayout::getIndexedOffset() to ↵Nuno Lopes
GEP::accumulateConstantOffset(). The later API is nicer than the former, and is correct regarding wrap-around offsets (if anyone cares). There are a few more places left with duplicated code, which I'll remove soon. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171259 91177308-0d34-0410-b5e6-96231b3b80d8

LCSSA PHIs may have undef values. The vectorizer updates values that are used by outside users such as PHIs. The bug happened because undefs are not loop values. This patch handles these PHIs.

For the time being this includes only some dummy test cases. Once the generic implementation of the intrinsics cost function does something other than assuming scalarization in all cases, or some target specializes the interface, some real test cases can be added. Also, for consistency, I changed the type of IID from unsigned to Intrinsic::ID in a few other places. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171079 91177308-0d34-0410-b5e6-96231b3b80d8
