[Bug tree-optimization/13761] [tree-ssa] component refs to the same struct should not alias

[rguenth at gcc dot gnu dot org]

------- Comment #14 from rguenth at gcc dot gnu dot org  2006-01-28 18:47 -------
The copyprop enhancement patch I have in development handles the case where the
stores are not constant.  I.e.

  int tmp = 1;
  f->s = tmp;
  f->s2 = 2;
  if (f->s != tmp)
    link_error ();

and -fno-tree-ccp.
