--- Comment #11 from Richard Biener <rguenth at gcc dot gnu.org> ---
If double_type_node is FE dependent then it needs treatment in
tree-streamer.c:preload_common_nodes:

static void
preload_common_nodes (struct streamer_tree_cache_d *cache)
{
  unsigned i;

  for (i = 0; i < itk_none; i++)
    /* Skip itk_char.  char_type_node is dependent on -f[un]signed-char.  */
    if (i != itk_char)
      record_common_node (cache, integer_types[i]);

  for (i = 0; i < stk_type_kind_last; i++)
    record_common_node (cache, sizetype_tab[i]);

  for (i = 0; i < TI_MAX; i++)
    /* Skip boolean type and constants, they are frontend dependent.  */
    if (i != TI_BOOLEAN_TYPE
        && i != TI_BOOLEAN_FALSE
        && i != TI_BOOLEAN_TRUE)
      record_common_node (cache, global_trees[i]);
}
