--- Comment #4 from Sam James <sjames at gcc dot gnu.org> ---
The loop does:


      while (insn && !NONDEBUG_INSN_P (insn))
        {

              gcc_assert (NOTE_P (insn)
                          && (NOTE_KIND (insn) == NOTE_INSN_FUNCTION_BEG
                              || NOTE_KIND (insn) == NOTE_INSN_BASIC_BLOCK));
..
          insn = NEXT_INSN (insn);
}

already?
