If they do, then they are not Instruction Set compatible. My copy of the SPARC architecture manual lists only a MULScc (Multiply Step and modify icc), and no divide or divide step instructions. Even if the hardware is there, it is hard to use without an instruction to specify the exact semantics of the operation! -- Tim Olson Advanced Micro Devices (tim@amd.com)
