--- Comment #1 from Jeffrey A. Law <law at gcc dot gnu.org> ---
Looks like non-canonical RTL to me.  Inside a MEM that shift should have been
turned into a multiply.

@item
Within address computations (i.e., inside @code{mem}), a left shift is
converted into the appropriate multiplication by a power of two.
