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.

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.

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