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 use libx86emu providing an interface so that any C function
can simulate any other C function in debug step mode. The
original H can even simulated itself simulating P.

 Can you show me a sample H? Is H a little program?

[...]
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?
