2002-10-08 - Change PHINode::removeIncomingValue to delete the phi node if the lastChris Lattner
incoming value is removed! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4078 91177308-0d34-0410-b5e6-96231b3b80d8
2002-10-08 - Checkin LARGE number of Changes to CEE pass that will make it much moreChris Lattner
powerful, but that are largely disabled. The basic idea here is that it is trying to forward branches across basic blocks that have PHI nodes in it, which are crucial to be able to handle cases like whet.ll. Unfortunately we are not updating SSA correctly, causing sim.c to die, and I don't have time to fix the regression now, so I must disable the functionality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4077 91177308-0d34-0410-b5e6-96231b3b80d8

2002-10-04Fix a nasty problem with dominance calculation for unreachable blocks.Chris Lattner
If we had a CFG that look like Entry -> B, Unreachable -> B, then we would not correctly determine that Entry dominated B, because Entry did not apparently dominate "unreachable". This patch fixes this by making the entry node dominate all blocks, including unreachable ones. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4037 91177308-0d34-0410-b5e6-96231b3b80d8
