Owen Anderson 0995f20cfd Give up on doing in-line instruction simplification during correlated value propagation. Instruction simplification ... needs to be guaranteed never to be run on an unreachable block. However, earlier block simplifications may have changed the CFG to make block that were reachable when we began our iteration unreachable by the time we try to simplify them. (Note that this also means that our depth-first iterators were potentially being invalidated). This should not have a large impact on code quality, since later runs of instcombine should pick up these simplifications. Fixes PR8506. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117709 91177308-0d34-0410-b5e6-96231b3b80d8		2010-10-29 21:05:17 +00:00
