--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
>I've attached a reduced reproducer which (unfortunately) still requires LTO, but it is at least fairly well reduced (only two small TUs).

One thing you could do is combine the 2 TUs (since they are small) and then use
-fwhole-program or add static on some of the variables. that might be enough to
get one TU.
