New Revision: 140933

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=140933
Log:
* haifa-sched.c (rank_for_schedule): Don't scan back for non-debug
insn past prev_head.
(schedule_insn): Don't mark debug insns as first in cycle.
(get_ebb_head_tail): Skip boundary debug insns.
(no_real_insns_p): Likewise.
(schedule_block): Ensure last_schedule_insn is not a boundary
debug insn.
(set_priorities): Reject boundary debug insns.
(prev_non_location_insn): New.
(check_cfg): Use it in assertions.
* sched-ebb.c (schedule_ebbs): Skip boundary debug insns.
* sched-deps.c (sd_init_insn): Mark debug insns as non-boundary.
(sd_finish_insn): Check that debug insns are marked.
(sched_analyze): Skip debug insns when searching back for call
before head.
* sched-int.h (DEBUG_INSN_SCHED_P): New.
(SCHEDULE_DEBUG_INSN_P, BOUNDARY_DEBUG_INSN_P): New.
* sched-rgn.c (init_ready_list): Skip boundary debug insns.
(free_block_dependencies): Test for no real insns first.
(schedule_region): Likewise, before setting priorities.
* config/ia64/ia64.c (emit_insn_group_barriers,
emit_all_insn_group_barriers): Ignore debug insns.
(final_emit_insn_group_barriers): Likewise.  Remove obsolete
code to avoid emitting barriers because of debug insns.
* config/rs6000/rs6000.c (get_next_active_insn): Skip debug
insns.
