This means that when HHH does correctly emulate 1 step that *it is a correct emulation* of this 1 step, thus making everyone that disagrees disagree with a tautology making them look foolish. We stipulate that the only measure of a correct emulation is the semantics of the x86 programming language. By this measure when 1 to ∞ steps of DDD are correctly emulated by each pure function x86 emulator HHH (of the infinite set of every HHH that can possibly exist) then DDD cannot possibly reach past its own machine address of 0000216b and halt. _DDD() [00002163] 55 push ebp ; housekeeping [00002164] 8bec mov ebp,esp ; housekeeping [00002166] 6863210000 push 00002163 ; push DDD [0000216b] e853f4ffff call 000015c3 ; call HHH(DDD) [00002170] 83c404 add esp,+04 [00002173] 5d pop ebp [00002174] c3 ret Size in bytes:(0018) [00002174] -- Copyright 2024 Olcott "Talent hits a target no one else can hit; Genius hits a target no one else can see."
