That is a requirement for most of commits, see http://gcc.gnu.org/contribute.html for the exact rules. I am investigating the problem. I'd guess you don't want to flush on DEBUG_INSN_Ps, because then you'd flush differently between -g and -g0. So perhaps something like: --- gcc/sched-deps.c 2013-06-01 10:03:00.678514521 +0200 +++ gcc/sched-deps.c 2013-06-01 10:05:03.119864726 +0200 @@ -2694,10 +2694,11 @@ sched_analyze_2 (struct deps_desc *deps, { if ((deps->pending_read_list_length + deps->pending_write_list_length) - > MAX_PENDING_LIST_LENGTH) + > MAX_PENDING_LIST_LENGTH + && !DEBUG_INSN_P (insn)) flush_pending_lists (deps, insn, true, true); add_insn_mem_dependence (deps, true, insn, x); - } + } sched_analyze_2 (deps, XEXP (x, 0), insn); but I haven't tested it. Note, in your patch the closing } was misplaced, it is supposed to line up with the opening {. Anyway, if you can't fix this really quickly, please revert your patch. Bootstrap failure on the most commonly used GCC target by developers should never be taken lightly. Jakub
