[Bug tree-optimization/38207] Union in structs are not well optimized

[rguenth at gcc dot gnu dot org]

------- Comment #4 from rguenth at gcc dot gnu dot org  2008-11-21 10:52 -------
Which means that we correctly optimize

int f(struct a *c)
{
  int d; 
  c->c = 1;
  d = c->a;
  c->c = 1;
  return c->a + d;
}
