New Revision: 122288
URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=122288
Log:
* loop-iv.c (implies_p): Detect additional cases where A implies B.
(determine_max_iter): Take additional LOOP arg; all callers changed.
Lose broken logic dealing with PLUS. Try to limit the upper bound by
one using simplifications.
