Subject:         * ldlang.c (print_output_section_statement): If the output section
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5590fba9534e101a6f41d7ad801442cf7af17f98;p=binutils-gdb.git

    * ldlang.c (print_output_section_statement): If the output section
        statement has an update_dot_tree expression, apply it to
        print_dot.
        (print_input_section): Do not update print_dot if it would move
        print_dot backwards.
        (lang_do_assignments_1): If the output section statement has an
        update_dot_tree expression apply it to dot.

  * ld-scripts/overlay-size.t (end_of_bss_overlays): Define.
  (end_of_text_overlays): Define.
  (end_of_data_overlays): Define.
  * ld-scripts/overlay-size-map.d: Add expected values for
  end_of_bss_overlays, end_of_text_overlays and
  end_of_data_overlays.
