2007-06-15  Kenneth Zadeck <zadeck@naturalbridge.com>

	* df.h (DF_FIRST_OPTIONAL_PROBLEM): Removed.
	(struct df_problem.free_blocks_on_set_blocks): New field.
	(struct dataflow.optional_p): New field.
	(df_bb_regno_last_use_find, df_insn_regno_def_p): Removed.
	(df_live_set_all_dirty): New function.
	* df-scan.c (df_scan_alloc): Initialize optional_p.
	(problem_SCAN): Initialize free_blocks_on_set_blocks.
	* df-core.c (df_set_blocks): Removed use of
	DF_FIRST_OPTIONAL_PROBLEM.  Now uses
	df_problem.free_blocks_on_set_blocks to determine which blocks are
	recycled.
	(df_remove_problem): Removed use of DF_FIRST_OPTIONAL_PROBLEM.
	(df_finish_pass): Removed use of DF_FIRST_OPTIONAL_PROBLEM.  Now
	uses dataflow.optional_p to determine if problem should be
	deleted.
	(rest_of_handle_df_initialize): Only start live problem if 
	-02 or above.
	(df_bb_regno_last_use_find, df_insn_regno_def_p): Removed.
	* df-problems.c (df_ru_alloc, df_rd_alloc, df_lr_alloc,
	df_live_alloc, df_urec_alloc, df_note_alloc): set optional_p.
	(problem_RU, problem_RD, problem_LR, problem_UREC, problem_CHAIN,
	problem_NOTE):  Initialize free_blocks_on_set_blocks.
	(df_lr_bb_local_compute): Recompute luids if df_live problem is
	not active.
	(df_live_set_all_dirty, df_note_alloc): New function.
	* regrename.c (merge_overlapping_regs): Change DF_LIVE_* to
	df_get_live_*.
	* sched_ebb.c (compute_jump_reg_dependencies): Ditto.
	* postreload.c (reload_combine): Ditto.
	* cse.c (cse_extended_basic_block): Ditto.
	* regmove.c (mark_flags_life_zones): Ditto.
	* rtlfactoring.c (split_blocks_after_seqs, split_pattern_seq,
	erase_matching_seqs): Ditto.
	* bt-load.c (compute_defs_uses_and_gen): Ditto.
	* integrate (allocate_initial_values): Ditto.
	* combine.c (reg_dead_at_p): Ditto.
	* resource.c (mark_target_live_regs): Ditto.
	* sched-rgn.c (check_live_1, update_live_1): Ditto.
	* config/sh/sh.c (find_r0_life_regions): Ditto.
	* global.c (rest_of_handle_global_alloc): Only add back df_live
	for -O > 1.
	* local-alloc.c (rest_of_handle_local_alloc): Only remove
	df_live for -O > 1.
	* ifcvt.c (dead_or_predicable): Change DF_LIVE_* to
	df_get_live_*.
	(if_convert): Make sure df_live is there at -O == 1.
	(pass_if_after_combine): Cleanup flags.
	* init-regs.c (initialize_uninitialized_regs): Make sure df_live
	is there at -O == 1.
