Chandler Carruth e773e8c3e5 Add a somewhat hacky heuristic to do something different from whole-loop ... rotation. When there is a loop backedge which is an unconditional branch, we will end up with a branch somewhere no matter what. Try placing this backedge in a fallthrough position above the loop header as that will definitely remove at least one branch from the loop iteration, where whole loop rotation may not. I haven't seen any benchmarks where this is important but loop-blocks.ll tests for it, and so this will be covered when I flip the default. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154812 91177308-0d34-0410-b5e6-96231b3b80d8		2012-04-16 13:33:36 +00:00
