Visual c++ inline assembly
How do i stop vc++ from adding default inline codes at the start and end of functions?
e.g. my code __declspec(dllexport) __stdcall XY(ST1*param1){
__asm{
mov ecx, 0x06;
mov esi, [param1];
mov edi, [local1];
rep movsd;
}
}_XY@4: push ebp mov ebp,esp push ebx push esi push edi mov ecx,00000006h mov esi,[ebp+08h] mov edi,[L100075C0] rep movsd pop edi pop esi pop ebx pop ebp retn 0004h I mean...i know it needs those...but i want to do them manually. Thanks  win Xp, Visual c++ 6.0

I am not sure, but I think you should change the calling convension and use something else

Put _declspec(naked) in the declaration. Not sure how you can combine it with the _declspec(dllexport), maybe just by doing it

You could also write your code in an assembler and link it in, if you think you can roll your own correctly.
