--- Comment #4 from Alexander Monakov <amonakov at gcc dot gnu.org> ---
It might have been nicer to adjust asms themselves, adding inputs/outputs for
each global reg, if we must pretend the asms implicitly read/write them. That
would allow any subsystem (df, sched-deps, whatever) to derive the rest
automatically, and would make it obvious in the IR/compiler dumps what's going
on.
