--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> ---
Re-confirmed.  IMO correctness trumps optimization, but possibly instead of
just allowing const DECL_P this should move down to default: handling and we
should handle INDIRECT_REF specially like we handle ADDR_EXPR in only
allowing const iff the address is invariant itself?
