Hal Finkel 2741d2cfdf Cleanup trip-count finding for PPC CTR loops (and some bug fixes). ... This cleans up the method used to find trip counts in order to form CTR loops on PPC. This refactoring allows the pass to find loops which have a constant trip count but also happen to end with a comparison to zero. This also adds explicit FIXMEs to mark two different classes of loops that are currently ignored. In addition, we now search through all potential induction operations instead of just the first. Also, we check the predicate code on the conditional branch and abort the transformation if the code is not EQ or NE, and we then make sure that the branch to be transformed matches the condition register defined by the comparison (multiple possible comparisons will be considered). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158607 91177308-0d34-0410-b5e6-96231b3b80d8		2012-06-16 20:34:07 +00:00
