Every C programmer that knows what an x86 emulator is knows
that when H0 emulates the machine language of Infinite_Loop,
Infinite_Recursion, and DDD that it must abort these emulations
so that itself can terminate normally.

When this is construed as non-halting criteria then simulating

Simulating termination analyzers must report on the behavior

simulation.

Richard just said that he affirms that when DDD correctly
simulated by HHH calls HHH(DDD) that this call returns even
though the semantics of the x86 language disagrees.

Therefore DDD correctly simulated by HHH DOES NOT HALT.
Thus HHH correctly reports that DDD DOES NOT HALT.

And HHH can not report that fact, because, to correct emulate, as presuemd, it can not stop it emulation.

If it does, it changes the behavior of DDD (remember, the code of HHH is PART of the code for DDD) and DDD will Halt.

You are just showing you are a stupid LIAR.

 *THIS PROVES THAT DDD CORRECTLY EMULATED BY HHH DOES NOT HALT*
The call from DDD to HHH(DDD) when N steps of DDD are
correctly emulated by any pure function x86 emulator
HHH at machine address 0000217a cannot possibly return.
