--- Comment #4 from Jan Hubicka <hubicka at gcc dot gnu.org> --- I think you can add cgraph predicate former_thunk_p which tests that return !thunk_p && (thunk_info.fixed_offset || virtual_offset_p || indirect_offset) Every thunk should set one of those (it may be good to also add sanity check that whenever thunk_p the second part of condition suceeds). This way you don't need to change all uses of thunk_p and patch won't break LTO streaming once backported to gcc8. Honza
