Your eyes are still very sharp! The new instructions are: SDIV, SDIVcc, SMUL, SMULcc, UDIV, UDIVcc, UMUL, UMULcc. Are there any more that SUN has snuck in? Has anybody tried to assemble these on 4.1? (My doco arrived without tapes!) Does 4.1 contain any provision to trap on them and emulate them? What are the opcodes SUN has assigned anyway? How do these new instructions fit into the concept of an Applications Binary Interface (ABI) standard? -- Geoff Bull Phone : (+61 48) 68 3490 Highland Logic Pty. Ltd.
