Dan Gohman c2695eba57 Revert 72493 and replace it with a more conservative fix, for now: don't ... rewrite the comparison if there is any implicit extension or truncation on the induction variable. I'm planning for IVUsers to eventually take over some of the work of this code, and for it to be generalized. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72496 91177308-0d34-0410-b5e6-96231b3b80d8		2009-05-27 21:10:47 +00:00
