--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I would have expected that before:
              if (node->root_p ())
                delete static_cast<fma_root_node *> (node);
we either process all the children of that root node, or remove the root node
and replace it with one of the children.
