[Piru]

The code misbehaves when called with count of 0. Here is a proper version:

Code: [Select]


void copy(int *to, int *from, int count)
{
  int n;

  if (!count)
    return;

  n = (count + 7) / 8;

  switch (count % 8)
  {
    case 0: do { *to++ = *from++;
    case 7: *to++ = *from++;
    case 6: *to++ = *from++;
    case 5: *to++ = *from++;
    case 4: *to++ = *from++;
    case 3: *to++ = *from++;
    case 2: *to++ = *from++;
    case 1: *to++ = *from++; } while (--n);
  }
}
