        PR rtl-optimization/39762
        * ira-int.h (ira_register_move_cost, ira_may_move_in_cost,
        ira_may_move_out_cost): Add comments about way of their usage.
        (ira_get_register_move_cost, ira_get_may_move_cost): New
        functions.

        * ira-conflicts.c (process_regs_for_copy): Use function
        ira_get_register_move_cost instead of global
        ira_register_move_cost.

        * ira-color.c (update_copy_costs, calculate_allocno_spill_cost,
        color_pass, move_spill_restore, update_curr_costs): Ditto.

        * ira-lives.c (process_single_reg_class_operands): Ditto.

        * ira-emit.c (emit_move_list): Ditto.

        * ira-costs.c (copy_cost): Don't call ira_init_register_move_cost.
        (record_reg_classes): Ditto.  Use functions
        ira_get_register_move_cost and ira_get_may_move_cost instead of
        global vars ira_register_move_cost, ira_may_move_out_cost and
        ira_may_move_in_cost.
        (record_address_regs): Don't call ira_init_register_move_cost.
        Use function ira_get_may_move_cost instead of global
        ira_may_move_in_cost.
        (process_bb_node_for_hard_reg_moves): Use function
        ira_get_register_move_cost instead of global
        ira_register_move_cost.
        (ira_costs): Don't call ira_init_register_move_cost.
