It is obviously not ideal, but the only pass between free_cfg and machine_reorg that can destroy the CFG is dbr_sched (delay branch scheduling). Anyway, out-of-tree port => INVALID. Feel free to re-open this bug report if you can reproduce it with an in-tree port, of course. -- steven at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- Status|WAITING |RESOLVED Resolution| |INVALID http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39274
