> What are the callers of gt_pch_p_9line_maps?

It is only called from gt_pch_nx_line_maps of ./gcc/gtype-desc.c (generated):

gt_pch_nx_line_maps (void *x_p)
{
  struct line_maps * const x = (struct line_maps *)x_p;
  if (gt_pch_note_object (x, x, gt_pch_p_9line_maps, gt_ggc_e_9line_maps))

      {
        size_t l0 = (size_t)(((*x).info_ordinary).used);
        if ((*x).info_ordinary.maps != NULL) {
          size_t i0;
          for (i0 = 0; i0 != (size_t)(l0); i0++) {
            switch (((*x).info_ordinary.maps[i0]).reason == LC_ENTER_MACRO)
              {
              case 0:
                gt_pch_n_S ((*x).info_ordinary.maps[i0].d.ordinary.to_file);
                break;
              case 1:

                  size_t l1 = (size_t)(2 *
