[Bug tree-optimization/36204] [4.4 Regression] missed store sinking out of a loop

------- Comment #5 from pinskia at gcc dot gnu dot org  2008-05-11 01:35 -------
Reverting that part of the patch causes an ICE with the following code:
 struct BUF1
{
  int b1;
  int b12;
};

void link_error();


int foo(int n, struct BUF1 * p)
{

    int i = 0;
    for (i = 0; i < 1024*1024; i++)
      p->b1 = 1;
    if (p->b1 != 1)
      link_error ();
    return 0;
}

Which means we can't even to LIM that case either :(.
