"...the Turing machine will halt whenever it enters a final state."
Linz(1990:234)

*If DD correctly simulated by HH can't possibly reach its own*
*final state then DD correctly simulated by HH is non-halting*

*When we get as specific as the actual x86 machine code of*
*DD then all liars are exposed*

typedef int (*ptr)();  // ptr is pointer to int function in C
00       int HH(ptr p, ptr i);
01       int DD(ptr p)
02       {
03         int Halt_Status = HH(p, p);
04         if (Halt_Status)
05           HERE: goto HERE;
06         return Halt_Status;
07       }
