31 // The sparc ld/st instructions cannot accomodate displacements > 13 bits long. | |
32 // The following "pseudo" sparc instructions (load/store) make it easier to use the indexed addressing mode | |

34 // | |
35 // When disp <= 13 bits long, a single load or store instruction is emitted with (disp + [d]). | |
36 // When disp > 13 bits long, code is emitted to set the displacement into the O7 register, | |
37 // and then a load or store is emitted with ([O7] + [d]). | |
38 // | |
