--- Comment #2 from Alexander Monakov <amonakov at gcc dot gnu.org> ---
Indeed, I think the build system should be passing -fno-lto for such
translation units, as their ABI is different from the rest.
I'm not sure limiting the inliner is enough, there's also IPA-RA and it's not
obviously safe w.r.t global-reg-var differences.
If there's a desire to support such usage "seamlessly", I'd really like to see
the same solution for this and toplevel asms: making such input translation
unit one LTO partition (i.e. not splitting or merging it with anything else).
