Subject: sorry again:)->extended asm problem
Date: Mon, 09 Aug 2004 15:20:00 -0000	[thread overview]
Message-ID: <20040809144126.17842.qmail@web52901.mail.yahoo.com> (raw)

sorry again. i generally dont make such mistyakes
while asking questiuons. but yes it should %0.

and i want it through pointers. earlier my program was
having all these things correct but somewhat later i
have done all these mistakes in the code and while
sending the problem i pasted this error code.
i guess the code below is correct and i have to
understand why array b is not initialised with the
value
1 #include<inttypes.h>
      2
      3
      4 int main()
      5 {
      6   uint8_t
a[8]={1,2,3,4,5,6,7,8},b[8]={0,0,0,0,0,0},i;
      7   uint8_t *m,*m1;
      8 
      9   m=a;
     10   m1=b;         //i have pointed m1 to b
     11   for(i=0;i<8;i++)
     12      printf("%d ",a[i]);
     13   printf("\n");
     14   asm("movq (%1), %%mm0 \n"
     15       "movq %%mm0, (%0) \n"
     16       :"=r"(m1)
     17       :"r"(m)
     18       );
     19 
     20   for(i=0;i<8;i++)
     21      printf("%d ",b[i]);
     22   return 0;
     23 }
so i expect that b should be initialised
the problem in this code is it is printing array b as
00000000
it is not moving the values
WHY?

thanks a lot
ankit
