Cameron Zwarich e35642342b Eliminate the use of dominance frontiers in PromoteMemToReg. In addition to ... 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. llvm-svn: 123609		2011-01-17 01:08:59 +00:00
