Dan Gohman a58a04921d Make Loop::getLoopLatch() work on loops which don't have preheaders, as ... it may be used in contexts where preheader insertion may have failed due to an indirectbr. Make LoopSimplify's LoopSimplify::SeparateNestedLoop properly fail in the case that it would require splitting an indirectbr edge. These fix PR5502. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89484 91177308-0d34-0410-b5e6-96231b3b80d8		2009-11-20 20:51:18 +00:00
