2007-08-08Global values also don't undead-ify pointers in our dead alloca's set.Owen Anderson
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40936 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-08Make handleEndBlock significantly faster with one trivial improvement,Owen Anderson
and one hack to avoid hitting a bad case when the alias analysis is imprecise. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40935 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-08Small improvement: if a function doesn't access memory, we don't need to scanOwen Anderson
it for potentially undeading pointers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40933 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-08Add some comments, remove a dead argument, and simplify some control flow.Owen Anderson
No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40932 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-08A few more small cleanups.Owen Anderson
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40922 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-08First round of cleanups from Chris' feedback.Owen Anderson
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40919 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-02Fix 80 col. violations.Owen Anderson

2007-08-01Rename FastDSE to just DSE.Owen Anderson
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40668 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-01Move FastDSE in to DeadStoreElimination.Owen Anderson
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40667 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-01Remove old DSE.Owen Anderson
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40666 91177308-0d34-0410-b5e6-96231b3b80d8
2007-05-06Fix typo in comment.Nick Lewycky

2007-05-03Drop 'const'Devang Patel
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@36662 91177308-0d34-0410-b5e6-96231b3b80d8
2007-05-02Use 'static const char' instead of 'static const int'.Devang Patel
Due to darwin gcc bug, one version of darwin linker coalesces static const int, which defauts PassID based pass identification. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@36652 91177308-0d34-0410-b5e6-96231b3b80d8
2007-05-01Do not use typeinfo to identify pass in pass manager.Devang Patel
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@36632 91177308-0d34-0410-b5e6-96231b3b80d8
2007-02-05Apply the VISIBILITY_HIDDEN field to the remaining anonymous classes inReid Spencer
the Transforms library. This reduces debug library size by 132 KB, debug binary size by 376 KB, and reduces link time for llvm tools slightly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33939 91177308-0d34-0410-b5e6-96231b3b80d8
2006-12-19Switch over Transforms/Scalar to use the STATISTIC macro. For each statisticChris Lattner
converted, we lose a static initializer. This also allows GCC to emit warnings about unused statistics. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32690 91177308-0d34-0410-b5e6-96231b3b80d8
2006-12-06Detemplatize the Statistic class. The only type it is instantiated withChris Lattner
is 'unsigned'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32279 91177308-0d34-0410-b5e6-96231b3b80d8
2006-08-27eliminate RegisterOpt. It does the same thing as RegisterPass.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29925 91177308-0d34-0410-b5e6-96231b3b80d8
2005-11-30Fix a bug where we didn't realize that vaarg reads memory. This fixesChris Lattner

2004-11-28Make DSE potentially more aggressive by being more specific about alloca sizes.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@18309 91177308-0d34-0410-b5e6-96231b3b80d8
2004-09-20Prototype these functions more accuratelyChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16432 91177308-0d34-0410-b5e6-96231b3b80d8
2004-09-01Changes For Bug 352Reid Spencer
Move include/Config and include/Support into include/llvm/Config, include/llvm/ADT and include/llvm/Support. From here on out, all LLVM public header files must be under include/llvm/. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16137 91177308-0d34-0410-b5e6-96231b3b80d8
2004-07-26Implement DeadStoreElim/alloca.llx by observing that allocas are dead at theChris Lattner
end of the function (either return or unwind) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15232 91177308-0d34-0410-b5e6-96231b3b80d8
2004-07-25* Substantially simplify how free instructions are handled (potentially fixingChris Lattner
a bug in DSE). * Delete dead operand uses iteratively instead of recursively, using a SetVector. * Defer deletion of dead operand uses until the end of processing, which means we don't have to bother with updating the AliasSetTracker. This speeds up DSE substantially. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15204 91177308-0d34-0410-b5e6-96231b3b80d8
2004-07-25Free instructions kill values too. This implements DeadStoreElim/free.llxChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15199 91177308-0d34-0410-b5e6-96231b3b80d8

2004-07-22This is a trivial dead store elimination pass. It very very simple andChris Lattner
can be improved in many ways. But: stop laughing, even with -basicaa it deletes 15% of the stores in 252.eon :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15101 91177308-0d34-0410-b5e6-96231b3b80d8
