But it doesn't, since HHH doesn't do an emulation that determines "non-halting behavior", and it does correctly emulate per the x86 language, and thus it doesn't "correctly" decide anything. You are just showing you don't understand the words you say, but are just a pathological lying idiot. > >> but HHH (correctly) reports that it could not reach the end of the >> simulation.
