--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Perhaps some of those checks on the other side are redundant and could be
turned e.g. into gcc_checking_assert of gcc_assert, I bet if the MEM_REF
doesn't overwrite all bits, but only some subset of them, then the destination
couldn't be a nonmem decl and thus couldn't be promoted.
