--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I think this comes from emit-rtl.c:
      /* If MEMREF is a LO_SUM and the offset is within the alignment of the
         object, we can merge it into the LO_SUM.  */
      if (GET_MODE (memref) !=3D BLKmode
          && GET_CODE (addr) =3D=3D LO_SUM
          && known_in_range_p (offset,
                               0, (GET_MODE_ALIGNMENT (GET_MODE (memref))
                                   / BITS_PER_UNIT)))
        addr =3D gen_rtx_LO_SUM (address_mode, XEXP (addr, 0),
                               plus_constant (address_mode,
                                              XEXP (addr, 1), offset));=
