All Turing machine deciders only compute the mapping

Look at the definition of a Turing Machine (e.g., the one here). The machine has states. Each state can be final or non-final. If the machine's state is non-final, in the next step the machine "does" something, namely, it can write something on the tape, move its head, and/or change its state to a different state. This is how the machine makes a progress.

 So, aborting the simulation when the machine has not yet reached its final state, is a violation of the Turing Machine.
 

void DDD()
{
   HHH(DDD);
   return;
}
So you don't understand that DDD simulated by
pure simulator HHH keeps repeating its first
line forever?

However, if the state is final, the machine just stops and continues no more. This will be its final setting, the head will not move anymore and the tape remains the same forever. This event is non- reversible and is what we call halting.

 Exactly. And halting is what DDD does, when not disturbed by a premature abort that violates the semantics of the x86 language.
