HHH is an emulating termination analyzer that emulates
the x86 machine code located at the address of a function
using a fully functional x86 emulator.

When HHH recognizes a non-terminating pattern in the
execution trace of its emulated input it aborts this
emulation and returns 0.

typedef void (*ptr)();
int HHH(ptr P);

int DD()
{
int Halt_Status = HHH(DD);
if (Halt_Status)
HERE: goto HERE;
return Halt_Status;
}

I challenged everyone here to provide the machine address
by machine address (AKA line by line) execution trace
of DD correctly emulated by HHH that reaches its own
"ret" instruction.

No one made any attempt to do this because they know that
this would prove that they are stupidly wrong to say that
my trace is incorrect.
