This code does compile and does conform to c17.

Everyone with sufficient knowledge of C can easily determine that D
correctly emulated by any *pure function* H (using an x86 emulator)
cannot possibly reach its own simulated final state at line 06 and halt.

Yeah, of course not, if H doesn’t halt.

you must pay careful attention to every single word. Maybe you
had no idea that *pure functions* must always halt.

Or maybe you did not know that every computation that never reaches

Since the claim is that H is also a computation, it holds for H, as well. That means that H *DOES NOT HALT* even if it stops running because it is no longer simulated.

You can assume a unicorn, but that does not make it existent. You can assume a simulating H that is a pure function and halts, but that does not make them existent. The set of such H is empty.

I do not ignore your claim. It is in fact exactly your claim that D does not reach line 04 that proves that the simulation of HH does not reach its own final state.

HH correctly simulated by HH cannot possibly reach its own final state and return to D in any finite number of steps of correct simulation.

 The dishonest dodge of the strawman deception CHANGE-THE-SUBJECT
fake rebuttal is the most common fake rebuttal that people try
to get way with.

Is that your reaction if your assumption is proved to be false?
If your claim turns out to be wrong? Is it dishonest to prove you wrong?
I am not changing the subject. As everybody following the thread knows, the claim that H halts belongs to the subject. So the CHANGE-THE-SUBJECT excuse is false.
I should have known. As soon as you are proved false, you try to get away with the accusation that it is dishonest.
But OK, I accept that you don't want a honest dialogue. You only want to hear supporters of your claims, all other reactions you find dishonest. So, you will never learn. I can no longer help you, if you refuse a honest dialogue.
