--- Comment #2 from Xidorn Quan <gnu-9fbaow at upsuper dot org> --- ABI requires a different alignment than in struct? That's interesting. But I think developers (I mean, users of compilers) are generally more interested on alignment requirement in struct rather than that for ABI, and most description of the concept "alignment" refers to that in struct, so it is probably better make alignof / alignas report that value.
