--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> 2011-03-17 15:12:19 UTC --- Ah, it isn't any difference between --enable-checking=release and --enable-checking=yes behavior of cc1, but instead just that haifa-sched.i is different. We are expanding D.2070_29 = &MEM[(struct V *)0B].v[D.2034_30]{lb: 0 sz: 12}; and expand that as (plus (const_int 0) (reg)).
