SSE2 Compiler Error

Question

I am trying to enter SSE2 and have tried the following sample program :

#include "stdafx.h"    
#include <emmintrin.h>

int main(int argc, char* argv[])
{
__declspec(align(16)) long mul; // multiply variable
__declspec(align(16)) int t1[100000]; // temporary variable
__declspec(align(16)) int t2[100000]; // temporary variable
__m128i mul1, mul2;
 for (int j = 0; j < 100000; j++)
 {
 t1[j] = j;
 t2[j] = j+1;
 } // set temporary variables to random values
 _asm
 {
  mov eax, 0
  label: movdqa xmm0, xmmword ptr [t1+eax]
  movdqa xmm1, xmmword ptr [t2+eax]
  pmuludq xmm0, xmm1
  movdqa mul1, xmm0
  movdqa xmm0, xmmword ptr [t1+eax]
  pshufd xmm0, xmm0, 05fh
  pshufd xmm1, xmm1, 05fh
  muludq xmm0, xmm1
  movdqa mul2, xmm0
  add eax, 16
  cmp eax, 100000
  jnge label
 }
 return 0;
 }

And get the following warnings and errors:

warning C4405: 'xmm0': identifier reserved word

error C2400: inline assembler syntax error in 'opcode'; found 'xmm0'

I tried to find possible causes, but most of the people who shared my problems used Visual C ++ 6.0, while I use Visual C ++ 8.0.

Any suggestions?

Well, the error disappears if you change

muludq xmm0, xmm1

to

pmuludq xmm0, xmm1

Are you sure you didn't just miss p there?

Edit: , muludq. mcow ( ) .
