That is EXACTLY the definition of Correct > Emulation. WELL INDOCTRINATED FALSE ASSUMPTIONS ARE NOT TRUTH. WELL INDOCTRINATED FALSE ASSUMPTIONS ARE NOT TRUTH. WELL INDOCTRINATED FALSE ASSUMPTIONS ARE NOT TRUTH. void Infinite_Loop() { HERE: goto HERE; } void Infinite_Recursion() { Infinite_Recursion(); } void DDD() { HHH(DDD); } Every C programmer that knows what an x86 emulator is knows that when HHH emulates the machine language of Infinite_Loop, Infinite_Recursion, and DDD that it must abort these emulations so that itself can terminate normally.
