PR middle-end/20991
* cgraph.h (cgraph_local_info): Add vtable_method field.
* varasm.c (mark_decl_referenced): If cgraph_global_info_ready
and node is vtable_method, finalized and not reachable, don't do
anything.
* class.c: Include cgraph.h.
(cp_fold_obj_type_ref): Set node->local.vtable_method.
* Make-lang.in (cgraph.o): Depend on $(CGRAPH_H).
* g++.dg/opt/pr20991.C: New test.
