------- Additional Comments From pinskia at gcc dot gnu dot org  2005-08-26 01:40 -------
Here is a testcase which fails on all targets which shows a testcase where both sides have side effects:
struct g{};
char y[3];
char *f = &y[0];
char *ff = &y[0];
void h(void)
{
  *((struct g*)(f++)) = *((struct g*)(ff++));
}

void abort (void);

int main(void)
{
  h();
  if (f != &y[1])
    abort();
  if (ff != &y[1])
    abort();
}
