copied!<p>This doesn't really answer the question, but is a helpful hint. Instead of mucking around with the OllyDbg.exe thing, you can make Visual Studio generate the asm file for you, which has the added bonus that it can put in the original source code as comments. This isn't a big deal for your current small project, but as your project grows, you may end up spending a fair amount of time figuring out which assembly code matches which source code.</p> <p>From the command line, you want the /FAs and /Fa options (<a href="http://msdn.microsoft.com/en-us/library/367y26c6(VS.80).aspx" rel="nofollow noreferrer">MSDN</a>).</p> <p>Here's part of the output for your example code (I compiled debug code, so the .asm is longer, but you can do the same thing for your optimized code):</p> <pre><code>_wmain PROC ; COMDAT ; 8 : { push ebp mov ebp, esp sub esp, 216 ; 000000d8H push ebx push esi push edi lea edi, DWORD PTR [ebp-216] mov ecx, 54 ; 00000036H mov eax, -858993460 ; ccccccccH rep stosd ; 9 : int x=5; int y=1024; mov DWORD PTR _x$[ebp], 5 mov DWORD PTR _y$[ebp], 1024 ; 00000400H $LN2@wmain: ; 10 : while(x) { x--; y/=2; } cmp DWORD PTR _x$[ebp], 0 je SHORT $LN1@wmain mov eax, DWORD PTR _x$[ebp] sub eax, 1 mov DWORD PTR _x$[ebp], eax mov eax, DWORD PTR _y$[ebp] cdq sub eax, edx sar eax, 1 mov DWORD PTR _y$[ebp], eax jmp SHORT $LN2@wmain $LN1@wmain: ; 11 : return x+y; mov eax, DWORD PTR _x$[ebp] add eax, DWORD PTR _y$[ebp] ; 12 : } pop edi pop esi pop ebx mov esp, ebp pop ebp ret 0 _wmain ENDP </code></pre> <p>Hope that helps!</p>
