--- Comment #10 from Alexander Monakov <amonakov at gcc dot gnu.org> ---
Bug 64420, which was marked as a duplicate, presents an example where there's
no diagnostics at build time (linking succeeds), but the resulting code is
wrong and will fail at runtime.

I believe the correct fix would be to disable LTO partitioning in a TU that
contains top-level asms (but in that TU only).  Is there something wrong with
such approach?
