2006-09-01Reserve space in the ValueNumberInfo vector. This speeds up live intervalChris Lattner
analysis 16% on crafty. Wrap long lines. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30012 91177308-0d34-0410-b5e6-96231b3b80d8

2006-09-01Iterative coallescing doesn't buy us anything (we get identical results onChris Lattner
crafty with and without it). Removing it speeds up live intervals 6%. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30010 91177308-0d34-0410-b5e6-96231b3b80d8
2006-09-01Don't confuse canonicalize and lookup. Fixes predsimplify.reg4.ll. AlsoNick Lewycky
corrects missing optimization opportunity removing cases from a switch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30009 91177308-0d34-0410-b5e6-96231b3b80d8
2006-08-31DAG combiner fix for rotates. Previously the outer-most condition checksEvan Cheng
for ROTL availability. This prevents it from forming ROTR for targets that has ROTR only. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29997 91177308-0d34-0410-b5e6-96231b3b80d8
2006-08-31Add a special case that speeds up coallescing a bit, but not enough.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29996 91177308-0d34-0410-b5e6-96231b3b80d8
2006-08-31Delete copies as they are coallesced instead of waiting until the end.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29995 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29993 91177308-0d34-0410-b5e6-96231b3b80d8
2006-08-31This program crashes the PredicateSimplifier. Not marked XFAIL becauseNick Lewycky
the PredicateSimplifier is skipped in make check anyways. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29992 91177308-0d34-0410-b5e6-96231b3b80d8
2006-08-31Properties where both Values weren't in the union (as being equal toNick Lewycky
another Value) weren't being found by findProperties. This fixes predsimplify.ll test6, a missed optimization opportunity. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29991 91177308-0d34-0410-b5e6-96231b3b80d8

2006-08-30Guess what happens when asserts are disabled. :(Chris Lattner
Also, the assert could never fire due to || instead of &&. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29977 91177308-0d34-0410-b5e6-96231b3b80d8

2006-08-30Instantiate Statistic<> in one place, not in every .o file that uses it.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29971 91177308-0d34-0410-b5e6-96231b3b80d8
2006-08-30Move to using the EquivalenceClass ADT. Removes SynSets.Nick Lewycky
If a branch's condition has become a ConstantBool, simplify it immediately. Removing the edge saves work and exposes up more optimization opportunities in the pass. Add support for SelectInst. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29970 91177308-0d34-0410-b5e6-96231b3b80d8

2006-08-29Teach the coallescer to coallesce live intervals joined by an arbitraryChris Lattner
number of copies, potentially defining live ranges that appear to have differing value numbers that become identical when coallsced. Among other things, this fixes CodeGen/X86/shift-coalesce.ll and PR687. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29968 91177308-0d34-0410-b5e6-96231b3b80d8

2006-08-29Do not rely on std::sort and std::erase to get list of uniqueDevang Patel
exit blocks. The output is dependent on addresses of basic block. Add and use Loop::getUniqueExitBlocks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29966 91177308-0d34-0410-b5e6-96231b3b80d8
