--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
We have a dup for this I think also omp simd related, can't find it right now.
The issue is that addr-expr forwarding in SCCVN (or rather generally address
VN for references) needs to be improved.
I should be assigned on the dup so let's assign me here, too.
