--- Comment #9 from Richard Earnshaw <rearnsha at gcc dot gnu.org> ---
Does that really do the right thing?  That is, does force_reg understand a
misaligned memory op?

Also, what if one memory operand is aligned, but the other not?  Don't we want
to have the right combination of aligned/misaligned instructions?
