Dan Gohman 5c89b5240c Re-apply r80926, with fixes: keep the domtree informed of new blocks ... that get created during loop unswitching, and fix SplitBlockPredecessors' LCSSA updating code to create new PHIs instead of trying to just move existing ones. Also, optimize Loop::verifyLoop, since it gets called a lot. Use searches on a sorted list of blocks instead of calling the "contains" function, as is done in other places in the Loop class, since "contains" does a linear search. Also, don't call verifyLoop from LoopSimplify or LCSSA, as the PassManager is already calling verifyLoop as part of LoopInfo's verifyAnalysis. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81221 91177308-0d34-0410-b5e6-96231b3b80d8		2009-09-08 15:45:00 +00:00
