Retrieve JIT output

by

While debugging your application in Visual Studio, you can right-click on a code where you have stopped (using breakpoint) and click “Go to Disassembly”. You can debug through native instructions.

As for doing that with *.exe files on disk, maybe you could use NGen to generate native output and then disassemble it (although I never tried that, so I can’t guarantee that it will work).

Here are some sample opcodes from simple arithmetic operation that was written in c#:

            int x = 5;
mov         dword ptr [ebp-40h],5 
            int y = 6;
mov         dword ptr [ebp-44h],6 
            int z = x + y;
mov         eax,dword ptr [ebp-40h] 
add         eax,dword ptr [ebp-44h] 
mov         dword ptr [ebp-48h],eax
