Andrew Trick 20151da8c3 [disable-iv-rewrite] Allow WidenIV to handle NSW/NUW operations ... better. Don't immediately give up when an add operation can't be trivially sign/zero-extended within a loop. If it has NSW/NUW flags, generate a new expression with sign extended (non-recurrent) operand. As before, if SCEV says that all sign extends are loop invariant, then we can widen the operation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139453 91177308-0d34-0410-b5e6-96231b3b80d8		2011-09-10 01:24:17 +00:00
