    * decl2.c (maybe_emit_vtables): Mark all vtable entries if
    devirtualizing.
    * init.c (build_vtbl_address): Don't mark destructor.
    * class.c (finish_struct_1): Add all classes to keyed_classes
    if devirtualizing.
libstdc++-v3/
    * libsupc++/cxxabi.h (class __pbase_type_info): __pointer_catch
    is pure, not inline.
