Perhaps thinking that working at IR level would prevent these live
registers issues, seconded by the fact that vCPU TLBs handling seem to
be tcg-target agnostic.

But I do understand your position, have no patch suggesting a viable
alternative implementation, and most of all don't want to take more of
your time.

I appreciated the discussion and your help Richard. Thanks again.
