--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Comparing PTRS_COMPARE_UNEQUAL={287,286} fre3 (287 doesn't occur in the list,
so it is never optimize using ptrs_compare_unequal, 286 is only optimize for
_286),
the differences are:
_286 = &MEM[(struct function *)this_9(D) + 100B].D.542596;
- if (&D.616011.D.542596 == _286)
- goto <bb 116>; [46.53%]
- else
- goto <bb 79>; [53.47%]
-
- <bb 79> [50.53%]:
...
and
- <bb 98> [45.34%]:
- if (&tmp == _286)
- goto <bb 111>; [26.74%]
- else
- goto <bb 99>; [73.26%]
-
- <bb 99> [33.22%]:
plus lots of renumbering of basic blocks; the number of skipped bbs is big
though.
