llvm/test/Transforms/LoopSimplify, branch release_31

LoopSimplify bug fix. Handle indirect loop back edges.

2012-03-20T21:24:52Z

Do not call SplitBlockPredecessors on a loop preheader when one of the predecessors is an indirectbr. Otherwise, you will hit this assert: !isa(Preds[i]->getTerminator()) && "Cannot split an edge from an IndirectBrInst" git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153134 91177308-0d34-0410-b5e6-96231b3b80d8

Replace all instances of dg.exp file with lit.local.cfg, since all tests are run with LIT now and now Dejagnu. dg.exp is no longer needed.

Patch reviewed by Daniel Dunbar. It will be followed by additional cleanup patches. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150664 91177308-0d34-0410-b5e6-96231b3b80d8

Make loop preheader insertion in LoopSimplify handle the case where the loop header is a landing pad correctly (by splitting the landingpad out of the loop header). Make some adjustments to the rest of LoopSimplify to make it clear that the rest of LoopSimplify isn't making bad assumptions about the presence of landing pads. PR11575.
