Dan Gohman f5a309e989 Use a sign-extend instead of a zero-extend when promoting a ... trip count value when the original loop iteration condition is signed and the canonical induction variable won't undergo signed overflow. This isn't required for correctness; it just preserves more information about original loop iteration values. Add a getTruncateOrSignExtend method to ScalarEvolution, following getTruncateOrZeroExtend. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64918 91177308-0d34-0410-b5e6-96231b3b80d8		2009-02-18 17:22:41 +00:00
