| | | | | | | | | - Loosen the restrictions when checking of it branches to a landing pad. - Make the loop more efficient by checking the '.insert' return value. - Do cheaper checks first. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@91101 91177308-0d34-0410-b5e6-96231b3b80d8
* A machine basic block may end in an unconditional branch, however it may haveBill Wendling2009-12-111-0/+5
| | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | reduce the size of relevant "ghostly" sentinels by a pointer. This attempt now makes the compactification dependent on the configure variable LLVM_COMPACT_SENTINELS and should not cause any bootstrap failures for llvm-gcc any more. Please note that this is not yet the final version, and (as settled with Chris) I shall take out the autofoo/cmake portions in the next days.
