Bill Wendling 4bde1ab82d A machine basic block may end in an unconditional branch, however it may have ... more than one successor. Normally, these extra successors are dead. However, some of them may branch to exception handling landing pads. If we remove those successors, then the landing pads could go away if all predecessors to it are removed. Before, it was checking if the direct successor was the landing pad. But it could be the result of jumping through multiple basic blocks to get to it. If we were to only check for the existence of an EH_LABEL in the basic block and not remove successors if it's in there, then it could stop actually dead basic blocks from being removed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@91092 91177308-0d34-0410-b5e6-96231b3b80d8		2009-12-11 01:49:14 +00:00
