Dan Gohman a1af757e0a Extend ScalarEvolution's getBackedgeTakenCount to be able to ... compute an upper-bound value for the trip count, in addition to the actual trip count. Use this to allow getZeroExtendExpr and getSignExtendExpr to fold casts in more cases. This may eventually morph into a more general value-range analysis capability; there are certainly plenty of places where more complete value-range information would allow more folding. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70509 91177308-0d34-0410-b5e6-96231b3b80d8		2009-04-30 20:47:05 +00:00
