2011-01-23Convert two std::vectors to SmallVectors for a 3.4% speedup running -scalarreplCameron Zwarich
on test-suite + SPEC2000 & SPEC2006. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124068 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-18Make a std::vector a SmallVector<*, 32> like the other vectors in the sameCameron Zwarich
function. This seems to be about a 1.5% speedup of -scalarrepl on test-suite with SPEC2000 and SPEC2006. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123731 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-18Remove outdated references to dominance frontiers.Cameron Zwarich
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123724 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-17Roll r123609 back in with two changes that fix test failures with expensiveCameron Zwarich
checks enabled: 1) Use '<' to compare integers in a comparison function rather than '<='. 2) Use the uniqued set DefBlocks rather than Info.DefiningBlocks to initialize the priority queue. The speedup of scalarrepl on test-suite + SPEC2000 + SPEC2006 is a bit less, at just under 16% rather than 17%. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123662 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-17Roll out r123609 due to failures on the llvm-x86_64-linux-checks bot.Cameron Zwarich
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123618 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-17Eliminate the use of dominance frontiers in PromoteMemToReg. In addition toCameron Zwarich
eliminating a potentially quadratic data structure, this also gives a 17% speedup when running -scalarrepl on test-suite + SPEC2000 + SPEC2006. My initial experiment gave a greater speedup around 25%, but I moved the dominator tree level computation from dominator tree construction to PromoteMemToReg. Since this approach to computing IDFs has a much lower overhead than the old code using precomputed DFs, it is worth looking at using this new code for the second scalarrepl pass as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123609 91177308-0d34-0410-b5e6-96231b3b80d8
