> Dunno, maybe? I see the lot of other "small" options are `intx`, and the change like that would proliferate to all architectures that set `OptoLoopAlignment` as their `product_pd`. It also raises the question if `CodeEntryAlignment` should also be `int`? I'd rather keep this patch small, to be honest.

Your comment makes sense.  Thanks.
