转换内联C汇编程序（Intel语法为AT＆T）

Question

I am trying to convert this function from MSVC++ to MINGW (this is the original MSVC function)

    VOID __declspec(naked) BNSTUB()
{
   __asm
   {
      pushad;
      call OnChatPacketReceived;
      TEST EAX,EAX;

      popad;
      jnz oldCall;

        MOV EAX,0;
      MOV DWORD PTR DS:[EBX+0x6FF3EBA0],1
      ret;
oldCall:
        CALL eax;
        MOV DWORD PTR DS:[EBX+0x6FF3EBA0],1
        ret;

   }
}

But I have problems with pushad and popad. they give me a "undeclared identifier"

Answer 1

pusha popa（无d）

Answer 2

在Mingw中，它可能被称为“ pushall”而不是“ pusha”：所以请尝试“ pushalld”和“ popalld”。

Answer 3

You can compile something in C and also keep the assembler listing with -S parameter. That should display the AT&T syntax in all its glory.
