Type: variable
Body removed by symtab_remove_unreachable_nodes
Visibility: semantic_interposition artificial
References:
Referring: r/1 (addr)
Availability: not_available
Varpool flags:
$2 = void
so we somehow remove the variable because either the DECL_INITIAL walks do not
work or because the C++ FE screws up in setting things up.
