[Bug tree-optimization/42203] std::copy() results to a call to memmove() and is not inlined in trivial cases

[pinskia at gcc dot gnu dot org]

------- Comment #3 from pinskia at gcc dot gnu dot org  2009-11-28 01:24 -------
Fixed in 4.5.
  a[0] = 0;
  a[1] = 1;
  memcpy (&b[0], &a[0], 8);
  D.8585_1 = b[1];
  return D.8585_1;
