--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Before we had:
  unsigned char link.9[0:18446744073709551615];
in the referenced variables
but after it is gone.

But it is still referened:
  MEM[(int[0:D.2753] *)&link.9] =3D .DEFERRED_INIT (0, 2, &"link"[0]);

release_ssa removes it but I have not looked into how.

Note the way ccp1 turns this VLA into a non-VLA might be an issue too ...=
