New Revision: 127557

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=127557
Log:
	* gcc/common.opt (fsel-sched-reset-tc-on-join): New option.
	* gcc/config/ia64/ia64.c (group_barrier_needed): Add heuristic.
	(struct bundle_state): New field.
	(issue_nops_and_insn): Initialize it.
	(insert_bundle_state): Minimize mid-bundle stop bits.
	(bundling): Print number of mid-bundle stop bits.  Minimize mid-bundle
	stop bits.  Check correct calculation of mid-bundle stop bits.
	* gcc/haifa-sched.c (schedule_block): Call sched_init_luids to reset
	scheduler datastructure before target generates new insns.
	* gcc/sched-deps.c (sched_has_condition_p): New function.  Adjust
	users of sched_get_condition to use it instead.
	(conditions_mutex_p): Add arguments indicating which conditions are
	reversed.  Use them.
	(sched_get_condition_with_rev): Rename from sched_get_condition.  Add
	argument to indicate whether returned condition is reversed.  Do not
	generate new rtx when condition should be reversed; indicate it by
	setting new argument instead.
	(sched_insns_mutex_p): Use sched_get_condition_with_rev.
	(deps_analyze_insn): Do not flush pending write lists on speculation
	checks.  Do not make speculation check a scheduling barrier for memory
	references.
	* gcc/sched-int.h (sel_insn_is_speculation_check): Declare.
	* gcc/sched-rgn.c (sched_rgn_init): Do not calculate and free
	dominance info for selective scheduler here.
	* gcc/sel-sched-dump.c (dump_expr_1): Print new field.
	* gcc/sel-sched-dump.h (enum dump_expr): New member.
	* gcc/sel-sched-ir.c (init_expr): New arguments.  Initialize new
	fields of expr_t.
	(copy_expr): Update to pass new arguments to init_expr.
	(copy_expr_onside): Ditto.
	(init_global_and_expr_for_insn): Ditto.
	(init_simplejump): Ditto.
	(merge_expr_data): Calculate new fields of expr_t.
	(sel_insn_is_speculation_check): New function.
	(get_seqno_of_a_pred): Remove wrong assertion.
	(init_insn): Calculate new field of expr_t.
	(sel_split_block): Ditto.
	(pipeline_outer_loops_finish): Do not free dominance info here.
	* gcc/sel-sched-ir.h (struct _expr): New fields.
	(EXPR_ORIG_BB_INDEX): New accessor macro.
	(EXPR_WAS_SUBSTITUTED): Ditto.
	* gcc/sel-sched.c (stat_bookkeeping_copies,
	stat_insns_needed_bookkeeping, stat_renamed_scheduled,
	stat_substitutions_total): New global variables.
	(in_fallthru_bb_p): New function.
	(extract_new_fences_from): Use it. 
	(moveup_rhs_inside_insn_group): Record whether expr was substituted.
	(moveup_rhs): Ditto.  Do not disable motion of exprs that might need
	bookkeeping.
	(CANT_MOVE_TRAPPING): Allow moving trapping insns through speculation
	checks.
	(sel_rank_for_schedule): New heuristic.
	(generate_bookkeeping_insn): Avoid creating new basic block.
	(max_uid_before_move_op): New global variable.
	(remove_insns_that_need_bookkeeping): New function.
	(fill_insns): Use it.  Adjust statistical counters.
	(move_op): Adjust statistical counter.
	(sel_region_finish): Cleanup.
	(sel_sched_region_2): Initialize statistical counters, print them.
	(sel_global_init): Always calculate dominance info.
	(sel_global_finish): Always free calculate dominance info.
