--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
On x86_64-linux we emit the same code, that is because the psABI is clear how
empty structures are passed there and that they don't occupy anything unless
they are non-trivial for ABI (e.g. non-trivial copy ctors).
But I think x86_64 is the only target to override targetm.calls.empty_record_p
