Dan Gohman 55e283c71e Revamp the loop unroller, extending it to correctly update PHI nodes ... in the presence of out-of-loop users of in-loop values and the trip count is not a known multiple of the unroll count, and to be a bit simpler overall. This fixes PR2253. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52645 91177308-0d34-0410-b5e6-96231b3b80d8		2008-06-23 21:29:41 +00:00
