2009-10-22Move if-conversion before post-regalloc scheduling so the predicated ↵Evan Cheng
instruction get scheduled properly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84843 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-22Load / store multiple was missing opportunites when the load / store bundles ↵Evan Cheng
are at the end of the bb. Test case is already in, the bug is exposed by subsequent commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84842 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-22move 'loading i32 from string' optimization from instcombineChris Lattner
to libanalysis. Instcombine shrinking... does this even make sense??? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84840 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-22Move some constant folding logic for loads out of instcombine intoChris Lattner
Analysis/ConstantFolding.cpp. This doesn't change the behavior of instcombine but makes other clients of ConstantFoldInstruction able to handle loads. This was partially extracted from Eli's patch in PR3152. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84836 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-22Revert the main portion of r31856. It was causing BranchFoldingDan Gohman
to break up CFG diamonds by banishing one of the blocks to the end of the function, which is bad for code density and branch size. This does pessimize MultiSource/Benchmarks/Ptrdist/yacr2, the benchmark cited as the reason for the change, however I've examined the code and it looks more like a case of gaming a particular branch than of being generally applicable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84803 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-21Make changes to rev 84292 as requested by Chris Lattner.Victor Hernandez
Most changes are cleanup, but there is 1 correctness fix: I fixed InstCombine so that the icmp is removed only if the malloc call is removed (which requires explicit removal because the Worklist won't DCE any calls since they can have side-effects). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84772 91177308-0d34-0410-b5e6-96231b3b80d8
