* The pass manager is not able to schedule -loop-deletion -loop-index-split.Devang Patel2008-08-141-0/+5
| | | | | | | | | | | | The loop-deletion pass does not preserve dom frontier, which is required by loop-index-split. When the PM checks dom frontier for loop-index-split, it has already verified that lcssa is availalble. However, new dom frontier forces new loop pass manager, which does not have lcssa yet. The PM should recheck availability of required analysis passes in such cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54805 91177308-0d34-0410-b5e6-96231b3b80d8
