basic-block.h (PROP_*): Move constants from ...
* basic-block.h (PROP_*): Move constants from ...
* flow.c: ... here.
(compute_bb_for_insn): Free the array before reallocating.
(update_life_info): New arg PROP_FLAGS; pass on to propagate_block.
(allocate_reg_life_data): Reset all reg variables collected by
propagate_block.
(get_block_head_tail): Don't convert from bb to block.
(get_bb_head_tail): New. Update all callers of get_block_head_tail.
(find_insn_reg_weight): Take block not bb.
(schedule_block): Don't set block num for moved insns.
(schedule_region): Don't update_life_info or find_insn_reg_weight.
(schedule_insns): Do it here instead.
* combine.c (combine_instructions): Invoke compute_bb_for_insn
before update_life_info.
* recog.c (split_all_insns, peephole2_optimize): Update for
new arg to update_life_info.
* rtlanal.c (remove_note): Cope with NULL note.
* toplev.c (rest_of_compilation): Don't invoke recompute_reg_usage
