Test fails for Cortex-M0 with:

.../pr81812.C:6:8: error: generic thunk code fails for method 'virtual void 
ChildNode::_ZTv0_n12_NK9ChildNode5errorEz(...) const' which uses '...'

According to PR108277, it's expected that thumb1 targets does not
support empty virtual functions with ellipsis.

gcc/testsuite/ChangeLog:

        * g++.dg/torture/pr81812.C: Add xfail for thumb1.

OK.  There's no reason that I can see why this can't be fixed.  It just needs 
somebody to write (and test) the code :)

Pushed as r15-6305-gf111d8e20b6.

Absolutely, but I don't see it as urgent to implement... ;)

Kind regards,
