--- Comment #23 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to H.J. Lu from comment #22) > This is a target independent issue. Clang++ skips empty struct argument > and g++ passes it. Skip empty struct argument requires middle-end changes. Except in c++, the struct is non zero in size.
