Counter-factual.
Halting is defined as reaching a final halt state.

void Infinite_Recursion()
{
   Infinite_Recursion();
   return;
}

void Infinite_Loop()
{
   HERE: goto HERE;
   return;
}

void DDD()
{
   HHH(DDD);
   return;
}

When it is understood that HHH does simulate itself
simulating DDD then any first year CS student knows
that when each of the above are correctly simulated
by HHH that none of them ever stop running unless aborted.
