> 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 ((*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:
