Chandler Carruth 2eb5a744b1 Rework a bit of the implementation of loop block rotation to not rely so ... heavily on AnalyzeBranch. That routine doesn't behave as we want given that rotation occurs mid-way through re-ordering the function. Instead merely check that there are not unanalyzable branching constructs present, and then reason about the CFG via successor lists. This actually simplifies my mental model for all of this as well. The concrete result is that we now will rotate more loop chains. I've added a test case from Olden highlighting the effect. There is still a bit more to do here though in order to regain all of the performance in Olden. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145179 91177308-0d34-0410-b5e6-96231b3b80d8		2011-11-27 09:22:53 +00:00
