Dan Gohman 33a9cb4f40 Make ISel ignore dead nodes. The DAGCombiner normally eliminates ... dead nodes, but in this case its missing one. Fixing the DAGCombiner is desirable, but it's somewhat involved. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58777 91177308-0d34-0410-b5e6-96231b3b80d8		2008-11-05 22:56:47 +00:00
