--- Comment #4 from Segher Boessenkool <segher at gcc dot gnu.org> --- The address for lxv and lxvx can be anything. The *offset* in the address for lxv has to be a multiple of sixteen. This isn't any different from DS-mode (well, multiple of 4 there), and we have DQ-mode instructions all over the place as well already anyway, lq is the obvious one. So what is special about lxv?
