------- Additional Comments From pinskia at gcc dot gnu dot org  2003-08-28 13:00 -------
I can confirm this on the mainline (20030827).
Reduced source:
void DecodeAC(int index,int *matrix)
{
  int *mptr;

  for(mptr=matrix+index;mptr<matrix+64;mptr++) {*mptr = 0;}
}
Comand line: gcc  -funroll-all-loops -ffast-math -O2 -mtune=i486 -march=pentium4 -
fprefetch-loop-arrays pr12092.c.
