--- 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?
