Chris Lattner 20e3d86766 The dag combiner is missing revisiting nodes that it really should, and thus leaving ... dead stuff around. This gets fed into the isel pass and causes certain foldings from happening because nodes have extraneous uses floating around. For example, if we turned foo(bar(x)) -> baz(x), we sometimes left bar(x) around. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46305 91177308-0d34-0410-b5e6-96231b3b80d8		2008-01-24 07:18:21 +00:00
