--- Comment #15 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So comment #0 is harder to implement copy prop for aggegrates. The reason is
you need to prove the two `l` and two `r` are exactly the same and the address
is taken for both of them.

The dup bugs 101474 and bug 115097 are fixed via the patch for PR 14295.
