* Roll r123609 back in with two changes that fix test failures with expensiveCameron Zwarich2011-01-171-50/+119
| | | | | | | | | | | | | | | 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

* Eliminate the use of dominance frontiers in PromoteMemToReg. In addition toCameron Zwarich2011-01-171-49/+118
| | | | | | | | | | | | | | 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
