* loop.c (basic_induction_var): Typo NULL_RTX -> NULL.

        (strength_reduce): Release the varrays from the no-bivs early exit.

        * reload1.c (order_regs_for_reload): Init hard_reg_n_uses before
        the loop over the registers.

        * tree.c (save_tree_status): Set maybepermanent_firstobj NULL
        for a new obstack.
        (restore_tree_status): Check that instead when freeing the obstack.
