--- Comment #8 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Though, judging from the fact that we print symtab_node::order into the
-fdump-final-insns= dumps:
;; Function selinux_ops (selinux_ops, funcdef_no=4, cgraph_uid=4,
symbol_order=4)
it should be ok (otherwise we'd have -fcompare-debug failures already).
For functions we could also use node->uid (either just that, or hash in both),
but we don't have those in the varpool.

So, I think I'll just add the testcase into the testsuite and bootstrap/regtest
this.
