I understand that your approach is to remove the "binary translation"
part of the vanilla qemu, because we dont need it. We only need the
device emulation code of qemu for kvm. Do I understand correctly?

If so, we do not need to depend on gcc3 tricks anymore. Removing the
dependent on gcc3 is really an important achievement.

Thanks,
Jun
