Chris Lattner a704ac8a66 Changes to support PHINode::removeIncoming changes 
llvm-svn: 4079
 2002-10-08 21:36:33 +00:00
Chris Lattner fae98a2d28 - Change PHINode::removeIncomingValue to delete the phi node if the last 
incoming value is removed!

Chris Lattner 736709feda - Checkin LARGE number of Changes to CEE pass that will make it much more 
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.

Chris Lattner d7b3bb0fa4 Handle post dominance correctly in the case where blocks do not have a path to 
the exit node.

llvm-svn: 4038
 2002-10-04 14:50:20 +00:00
Chris Lattner 2cedf1ce82 Fix a nasty problem with dominance calculation for unreachable blocks. 
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.
