  // The sparc ld/st instructions cannot accomodate displacements > 13 bits long.

  // The following "pseudo" sparc instructions (load/store) make it easier to use the indexed addressing mode

  // by allowing 32 bit displacements:

  //

  //    When disp <= 13 bits long, a single load or store instruction is emitted with (disp + [d]).

  //    When disp >  13 bits long, code is emitted to set the displacement into the O7 register,

  //       and then a load or store is emitted with ([O7] + [d]).
