* Add a DominatorTree argument to isLCSSA so that it doesn't have toDan Gohman2010-03-101-6/+0

* Add Loop contains utility methods for testing whether a loopDan Gohman2009-12-181-4/+4
| | | | | | | | | contains another loop, or an instruction. The loop form is substantially more efficient on large loops than the typical code it replaces. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@91654 91177308-0d34-0410-b5e6-96231b3b80d8

* Teach LoopUnroll how to bail if LoopSimplify can't give it what it needs.Dan Gohman2009-11-051-1/+12

* Revert r85667. LoopUnroll currently can't call utility functions whichDan Gohman2009-10-311-1/+47
| | | | | | | | auto-update the DominatorTree because it doesn't keep the DominatorTree current while it works. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85670 91177308-0d34-0410-b5e6-96231b3b80d8
* Merge the enhancements from LoopUnroll's FoldBlockIntoPredecessor intoDan Gohman2009-10-311-47/+1
| | | | | | | | MergeBlockIntoPredecessor. This makes SimplifyCFG slightly more aggressive, and makes it unnecessary for LoopUnroll to have its own copy of this code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85667 91177308-0d34-0410-b5e6-96231b3b80d8
