(ira_allocno_live_ranges_intersect_p, ira_pseudo_live_ranges_intersect_p): Remove. * ira-conflicts.c (ira_allocno_live_ranges_intersect_p, ira_pseudo_live_ranges_intersect_p): Rename to allocnos_have_intersected_live_ranges_p and pseudos_have_intersected_live_ranges_p. Move them from here to ... * ira-color.c: ... here (coalesced_allocno_conflict_p): Use allocnos_have_intersected_live_ranges_p. (coalesced_allocnos_living_at_program_points, coalesced_allocnos_live_at_points_p, set_coalesced_allocnos_live_points): Remove. (slot_coalesced_allocnos_live_ranges, slot_coalesced_allocno_live_ranges_intersect_p, setup_slot_coalesced_allocno_live_ranges): New. (coalesce_spill_slots): Use ranges of coalesced allocnos. (ira_sort_regnos_for_alter_reg): Use allocnos_have_intersected_live_ranges_p. (ira_reuse_stack_slot): Use pseudos_have_intersected_live_ranges_p. * global.c (pseudo_for_reload_consideration_p): Check flag_ira_share_spill_slots too. * ira-build.c (copy_allocno_live_range_list): Rename to ira_copy_allocno_live_range_list. Make it external. (merge_ranges): Rename to ira_merge_allocno_live_ranges. Make it external. (ira_allocno_live_ranges_intersect_p): New. (ira_finish_allocno_live_range_list): New. (finish_allocno): Use it. (remove_unnecessary_allocnos): Use ira_merge_allocno_live_ranges. (copy_info_to_removed_store_destinations): Ditto. Use ira_copy_allocno_live_range_list. (ira_flattening): Use ira_merge_allocno_live_ranges. * ira.c (too_high_register_pressure_p): New function. (ira): Switch off sharing spill slots if the pressure is too high.
