[Bug rtl-optimization/14237] suboptimal comparison between long and long long


------- Additional Comments From pinskia at gcc dot gnu dot org  2004-11-03 18:14 -------
For PPC, we have:
        cmplw cr7,r0,r9
        cmpw cr6,r0,r9
        bgtlr- cr7
        beq- cr6,L6
equality test can be done logically or arthimaticly so we don't need both cmp*'s.
