[Bug c++/39480] generated memcpy causes trouble in assignment

[rguenth at gcc dot gnu dot org]

------- Comment #21 from rguenth at gcc dot gnu dot org  2009-03-18 09:47 -------
For

struct A
{
  int i[200];
};

struct A *p1, *p2;
void f()
{
  *p1 = *p2;
}

we are sure that either p1 == p2 or *p1 and *p2 do not overlap because
otherwise there would be an alias violation.
