We don't show any of HHH and show the execution trace of
of just DDD assuming that HHH is an x86 emulator.

 This assumption is incorrect if it means that HHH is an unconditional simulator that does not abort.

This algorithm is used by all the simulating termination analyzers:

     *If simulating halt decider H correctly simulates its input D*
     *until H correctly determines that its simulated D would never*
     *stop running unless aborted* then
     H can abort its simulation of D and correctly report that D
     specifies a non-halting sequence of configurations.

You must have attention deficit disorder if you cannot pay
attention to the fact that I have said these same words many
many times:

     *until H correctly determines that its simulated D would never*
     *stop running unless aborted*

When we see the first four lines of DDD after main() has
called HHH(DDD) we know that HHH has emulated these first
four lines correctly.
