Because I have repeated this same point 500 times in the last three years...

If you understand the x86 language and can't tell how DDD
emulated by HHH differs from DDD emulated by HHH1 by the
following then you are probably lying about understanding
the x86 language.
*I did annotate it a little better this time*
typedef void (*ptr)();
int HHH(ptr P);
int HHH1(ptr P);
void DDD()
{
   HHH(DDD);
}
int main()
{
   HHH1(DDD);
}
*You really don't need to know one damn thing else besides this*
*You really don't need to know one damn thing else besides this*
*You really don't need to know one damn thing else besides this*
All that you have to know is that HHH and HHH1 are x86 emulators
and that HHH sees that same repeated state (first four lines of DDD)
that anyone knowing the x86 language can see.
