--- Comment #3 from Arseny Solokha <asolokha at gmx dot com> --- (In reply to Alexander Monakov from comment #1) > If you still have the compiler binary, you can help out by testing with > sel-sched debug counters: if you append -fdbg-cnt=sel_sched_insn_cnt:0 to > the "bad" command line, it should work again (as sel-sched will not move > anything), with -fdbg-cnt=sel_sched_insn_cnt:99999 it should fail. We use > this for isolating a problematic transformation (by bisecting on the counter > value). It still works w/ counter value 79, starts failing at 80.
