Only software engineers will understand that DD correctly simulated by HH had different behavior than DD(DD). Comp Sci people allow Comp Sci dogma to overrule verified facts. When I pinned Richard down on this he simply said that he does not care that DD correctly simulated by HH has different behavior than DD(DD). It turns out that DD correctly simulated by HH the behavior that the input to HH(DD,DD) specifies. Deciders are ONLY accountable for their actual inputs. Deciders compute the mapping FROM THEIR INPUTS... typedef int (*ptr)(); // ptr is pointer to int function in C 00 int HH(ptr p, ptr i); 01 int DD(ptr p) 02 { 03 int Halt_Status = HH(p, p); 04 if (Halt_Status) 05 HERE: goto HERE; 06 return Halt_Status; 07 } 08 09 int main() 10 { 11 HH(DD,DD); 12 return 0; 13 } DD correctly emulated by HH with an x86 emulator cannot possibly reach past its own machine instruction [00001c2e] in any finite (or infinite) number of steps of correct emulation. _DD() [00001c22] 55 push ebp [00001c23] 8bec mov ebp,esp [00001c25] 51 push ecx [00001c26] 8b4508 mov eax,[ebp+08] [00001c29] 50 push eax ; push DD 1c22 [00001c2a] 8b4d08 mov ecx,[ebp+08] [00001c2d] 51 push ecx ; push DD 1c22 [00001c2e] e80ff7ffff call 00001342 ; call HH [00001c33] 83c408 add esp,+08 [00001c36] 8945fc mov [ebp-04],eax [00001c39] 837dfc00 cmp dword [ebp-04],+00 [00001c3d] 7402 jz 00001c41 [00001c3f] ebfe jmp 00001c3f [00001c41] 8b45fc mov eax,[ebp-04] [00001c44] 8be5 mov esp,ebp [00001c46] 5d pop ebp [00001c47] c3 ret Size in bytes:(0038) [00001c47] -- Copyright 2024 Olcott "Talent hits a target no one else can hit; Genius hits a target no one else can see."
