--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Note, tree-object-size.c has been added several releases before MEM_REF has been added (4.1 vs. 4.6), so some kludges to deal with that had to be added, but the waccess stuff has been added only several years after SCCVN has been doing this, so it should just have not been added like that at all.
