*Simulating Termination Analyzer HHH(DDD) rejects input DDD*
HHH is an emulating termination analyzer that takes the machine
address of DDD as input then emulates the x86 machine language
of DDD until a non-terminating behavior pattern is recognized.
 *HHH recognizes this pattern when HHH emulates itself emulating DDD*
 void DDD()
{
   HHH(DDD);
   return;
}
 The above code shows that if HHH(DDD) rejects then DDD halts, which
means that no program that rejects DDD is a halting decider.
 
 DDD emulated by each corresponding HHH that can possibly
exist never returns
That does not make sense without a definition of "each corresponding
HHH that can possibly exist".

thus each of the directly executed  HHH emulators that does
return 0 correctly reports the above non-terminating behavior.
If HHH returns 0 to DDD then DDD halts, proving that HHH is not a
halt decider.
If HHH returns 1 to DDD then DDD halts, failing to prove that HHH is
not a halt decider.
If HHH does not return to DDD it is not a halt decider.
