--- Comment #13 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This is fixed in GCC 6, we produce:
_76 = MIN_EXPR <offset_99, 255>;
offset_75 = MAX_EXPR <_76, 1>;
...
_104 = offset_75 + -1;
Rather than:
offset_30 = _52 <= 254 ? offset_67 : 1;
prephitmp_119 = _52 <= 254 ? pretmp_118 : 0;
_17 = offset_67 <= 255;
offset_69 = _17 ? offset_30 : 255;
prephitmp_109 = _17 ? prephitmp_119 : 254;
This was fixed by r6-528. PR 66002 is describing almost the same issue even.
