2007-10-29Add a first attempt at dominator information for MBB's. Use with caution: ↵Owen Anderson
this has been tested to compile. It has not yet been confirmed to generate correct analysis. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43438 91177308-0d34-0410-b5e6-96231b3b80d8

2007-10-18Move Split<...>() into DomTreeBase. This should make the #include's of ↵Owen Anderson
DominatorInternals.h in CodeExtractor and LoopSimplify unnecessary. Hartmut, could you confirm that this fixes the issues you were seeing? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43115 91177308-0d34-0410-b5e6-96231b3b80d8

DomTreeNode by making it a typedef of a templated DomTreeNodeBase. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42743 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-03Completely merge the implementation details of DomTree and PostDomTree.Owen Anderson
Also, add a FIXME for a bug in PostDomTree calculation I noticed while writing this, git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42593 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-03Factor some code from the DomTree and PostDomTree calculate methods up into Owen Anderson
each one's runOnFunction method. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42563 91177308-0d34-0410-b5e6-96231b3b80d8

2007-09-30Template-ize more of the DomTree internal implementation details. Only the ↵Owen Anderson
calculate() methods for DomTree and PostDomTree remain to be merged/template-ized. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42476 91177308-0d34-0410-b5e6-96231b3b80d8

2007-09-27Convert DFSPass into a templated friend function, in preparation for making ↵Owen Anderson
it common to DomTree and PostDomTree. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42420 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-24Merge significant portions of the DomTree and PostDomTree implementations.Owen Anderson
The two remaining unmerged parts are DFSPass, and the Calculate(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42255 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-23Factor the calculation details for PostDomTree out of PostDominators.cpp andOwen Anderson
into a separate header file. Next step: merging PostDominatorCalculation.h with DominatorCalculation.h. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42251 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-23Move DFSPass back down into DominatorTree. I need to figure out what the ↵Owen Anderson
difference is between it and the PostDomTree version first. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42250 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-23Factor the dominator tree calculation details out into ↵Owen Anderson
DominatorCalculation.h. This change is not useful in and of itself, but it lays the groundwork for combining the dominator and postdominator implementations. Also, factor a few methods that are common to DominatorTree and PostDominatorTree into DominatorTreeBase. Again, this will make merging the two calculation methods simpler in the future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42248 91177308-0d34-0410-b5e6-96231b3b80d8
