Chris Lattner 125991a1f6 Fix this buggy transformation. Two observations: ... 1. we already know the value is dead, so don't bother replacing it with undef. 2. The very case the comment describes actually makes the load live which asserts in deletenode. If we do the replacement and the node becomes live, just treat it as new. This fixes a failure on X86/2008-01-16-InvalidDAGCombineXform.ll with some local changes in my tree. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46306 91177308-0d34-0410-b5e6-96231b3b80d8		2008-01-24 07:57:06 +00:00
