--- Comment #12 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I had a brief look at why there is the difference in DECL_ALIGN on TYPE_DECL
in this case, and the difference seems to come up from whether the type
size/layout has been finalized before calling layout_decl on the corresponding
TYPE_DECL or not.  The question is if we ever except for the arm/aarch64 bug
ever care about DECL_ALIGN on TYPE_DECLs, if yes, perhaps finalize_type_size
should check if type or any variant's TYPE_NAME is a TYPE_DECL and in that case
relayout_decl it?
