So, you created a simulator for x86? 32-bit I am assuming. Fwiw, I am interested on how you simulate the cmpxchg8b and/or the cmpxchg16b functions?

 I notice this:
  typedef int (*ptr)();  // ptr is pointer to int function
00 int H(ptr p, ptr i);
01 int D(ptr p)
02 {
03   int Halt_Status = H(p, p);
04   if (Halt_Status)
05     HERE: goto HERE;
06   return Halt_Status;
07 }
08
09 int main()
10 {
11   H(D,D);
12   return 0;
13 }
 But, where is H?

Every element of an infinite set of H/D pairs matching the above
template where H correctly simulates 1 to ∞ steps of D thus including
0 to ∞ recursive simulations of H simulating itself simulating D.
*D correctly simulated by H never reaches its own line 06 and halts*
