显然Release模式下编译会少很多代码。我写的if里的代码全部没有编译。DEBUG模式则是全部正常的。请问是为什么
源码是这样的
void My_ReadProcessMemory(DWORD Eax,
HANDLE hProcess,
LPCVOID lpBaseAddress,
LPVOID lpBuffer,
DWORD nSize,
LPDWORD lpNumberOfBytesRead
)
{
if (!IsMe)
{
IsMe =true;
MessageBox(NULL,"","",NULL);
if ((DWORD)lpBaseAddress>=0x6f000000&&(DWORD)lpBaseAddress <=0x6F705000)
{
hProcess=nOK;
DWORD lpnew;
lpnew=(DWORD)lpBaseAddress-0x6f000000;
lpnew+=(DWORD)gamedllbuf;
(LPCVOID)lpBaseAddress=(LPCVOID)lpnew;
}
IsMe = false;
}
}
用Release编译出来的代码为
10009530 cmp byte ptr [IsMe (1002FBB8h)],0
10009537 jne My_ReadProcessMemory+2Bh (1000955Bh)
10009539 push 0
1000953B push offset string "" (10007354h)
10009540 push offset string "" (10007354h)
10009545 push 0
10009547 mov byte ptr [IsMe (1002FBB8h)],1
1000954E call dword ptr [__imp__MessageBoxA@16 (10001408h)]
10009554 mov byte ptr [IsMe (1002FBB8h)],0
1000955B ret
用Debug编译出来的代码为
10111E50 push ebp
10111E51 mov ebp,esp
10111E53 sub esp,0CCh
10111E59 push ebx

10111E96 cmp esi,esp
10111E98 call @ILT+34760(__RTC_CheckEsp) (100B67CDh)
