Yes, the mode promotion triggers the alignment promotion on strict-alignment targets and the specified alignment is thus equal to the default one, so the code works as intended and clears DECL_USER_ALIGN. Not very clear what to do, but the most robust approach would be to use lookup_attribute on the type. -- Eric Botcazou
