Richard Kenner 0e1c7fc777 (make_range): Don't merge unsigned case with range containing upper bound; ... instead merge just with zero and convert a range with no upper bound to opposite one with no lower bound. (merge_ranges): In (+,-) case, don't treat subset specially if the upper bounds are the same; fix typo in others case here. From-SVN: r13090		1996-11-01 09:49:54 -05:00
