Assembler Code

[stream]

I use Code::Blocks with the "Microsoft Visual C++ Toolkit 2003" compiler and I've imported a project made in VC++.
There is some code in assembler and it doesn't compile.

_asm
{
   mov edi,h.mDstP
   mov esi,h.mSrcP
   mov ecx,h.mRunLength

   copyloop:
      movzx eax,WORD PTR [esi]
      add esi,4

      mov [edi],ax
      add edi,2

      dec ecx
      jnz copyloop
   
   mov h.mDstP,edi
   mov h.mSrcP,esi
}
The compiler doesn't know what _asm is.
How can I compile the assembler code?Do u have any ideas? I'd appreciate some help

Hi,
use "__asm" instead of "_asm".

I've tried using "__asm" instead of "_asm" and it doesn't change a thing.
I get the same compiler error : DDI_ASM_CopyPixels16.cpp(1) : error C2059: syntax error : '__asm'

Strange, becouse "__asm" works for me (I also use MS VC Toolkit 2k3 + Platform SDK). This code was compiled without errors:

Code

 //glFrustum(-0.104f,0.104f,-0.058f,0.058f,0.1f,100.0f);
    __asm
    {
        push    0x40590000; ///
        push    0;          //   100.0
        push    0x3FB99999; ///
        push    0x9999999A; //   0.1

        mov     eax,0x0E560419

        push    0x3FADB22D; ///
        push    eax;        //   0.058
        push    0xBFADB22D; ///
        push    eax;        //  -0.058

        mov     eax,0x76C8B439

        push    0x3FBA9FBE; ///
        push    eax;        //   0.104
        push    0xBFBA9FBE; ///
        push    eax;        // -0.104

        call    dword ptr glFrustum
    }

Working binary: http://www.icpnet.pl/~groman/Release.rar - it's my lame demo in C++ with lot of asm, it uses OpenGL.

you must have some other syntax error in your program, i just checked, and  the following sample with your asm code compiles and runs quite fine using VCTK2003

Code

#include <stdio.h>
#include <stdlib.h>

typedef struct tagHS {
	__int32* mSrcP;
	__int16* mDstP;
	int mRunLength;
} HS ;

void cpInt2Short(HS h) {
_asm {
	mov edi,h.mDstP
	mov esi,h.mSrcP
	mov ecx,h.mRunLength

copyloop:
	movzx eax,WORD PTR [esi]
	add esi,4

	mov [edi],ax
	add edi,2

	dec ecx
	jnz copyloop

	mov h.mDstP,edi
	mov h.mSrcP,esi
 }
}


void someasmfoo( void)
{

#define LENGTH 10

	__int32 ia1[LENGTH];
	__int16 ia2[LENGTH];
	HS h;

	for(int i=0; i<LENGTH; i++){
		ia1[i] = i+100;
	}

	h.mRunLength = LENGTH;
	h.mSrcP = ia1;
	h.mDstP = ia2;

	cpInt2Short(h);

	for(int i=0; i<LENGTH; i++){
		printf("i: %i , ia1: %i , ia2: %i\n",i,ia1[i],ia2[i]);
	}
}


int main()
{
	someasmfoo();
	printf("done.\n");
	return 0;
}

I've made a new project and tryed some assembler code and it worked just fine. The assembler code seems not to be the problem. I think the problem is the order in wich files are beeing compiled.
It's so confusing because in VC++ it compiles perfectly and I've noticed that the file compilation order in VC++ differs from that in C::B.
Do you have any ideas how may I fix this or what else could be wrong?
I apreciate your concern.

I have no idea. Compress your project and put it here. Maybe somebody looks into it and will help you.

thanx for your concerne, but I've managed top compile it.
The problem occur when I've imported the VC++ project, it forgot some settings - and i've had to cycle through all the cpp files and select the ones that compile and link  and the ones that don't.
