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
2012-12-03Use the new script to sort the includes of every file under lib.Chandler Carruth
Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-13Uniformize the InstructionSimplify interface by ensuring that all routinesDuncan Sands
take a TargetLibraryInfo parameter. Internally, rather than passing TD, TLI and DT parameters around all over the place, introduce a struct for holding them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152623 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-14Move Instruction::isSafeToSpeculativelyExecute out of VMCore andDan Gohman
into Analysis as a standalone function, since there's no need for it to be in VMCore. Also, update it to use isKnownNonZero and other goodies available in Analysis, making it more precise, enabling more aggressive optimization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146610 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-02split dom frontier handling stuff out to its own DominanceFrontier header,Chris Lattner
so that Dominators.h is *just* domtree. Also prune #includes a bit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122714 91177308-0d34-0410-b5e6-96231b3b80d8

enabling more PRE. PR8586. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119704 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-16In which I discover the existence of loops. Threading an operationDuncan Sands
over a phi node by applying it to each operand may be wrong if the operation and the phi node are mutually interdependent (the testcase has a simple example of this). So only do this transform if it would be correct to perform the operation in each predecessor of the block containing the phi, i.e. if the other operands all dominate the phi. This should fix the FFMPEG snow.c regression reported by İsmail Dönmez. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119347 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-24Reapply r97010, the speculative revert failed.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97036 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-24Speculatively revert r97010, "Add an argument to PHITranslateValue to specifyDaniel Dunbar
the DominatorTree. ...", in hopes of restoring poor old PPC bootstrap. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97027 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-24Add an argument to PHITranslateValue to specify the DominatorTree. If thisBob Wilson
argument is non-null, pass it along to PHITranslateSubExpr so that it can prefer using existing values that dominate the PredBB, instead of just blindly picking the first equivalent value that it finds on a uselist. Also when the DominatorTree is specified, have PHITranslateValue filter out any result that does not dominate the PredBB. This is basically just refactoring the check that used to be in GetAvailablePHITranslatedSubExpr and also in GVN. Despite my initial expectations, this change does not affect the results of GVN for any testcases that I could find, but it should help compile time. Before this change, if PHITranslateSubExpr picked a value that does not dominate, PHITranslateWithInsertion would then insert a new value, which GVN would later determine to be redundant and would replace. By picking a good value to begin with, we save GVN the extra work of inserting and then replacing a new value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97010 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-23Convert debug messages to use dbgs(). Generally this meansDavid Greene
s/errs/dbgs/g except for certain special cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92046 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-09Add a minor optimization: if we haven't changed the operands of anChris Lattner
add, there is no need to scan the world to find the same add again. This invalidates the previous testcase, which wasn't wonderful anyway, because it needed a run of instcombine to permute the use-lists in just the right way to before GVN was run (so it was really fragile). Not a big loss. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90973 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-09fix PR5733, a case where we'd replace an add with a lexically identical Chris Lattner
binary operator that wasn't an add. In this case, a xor. Whoops. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90971 91177308-0d34-0410-b5e6-96231b3b80d8
