I'll assume 48b of Immediate ? > AFAIK OR64 still uses 32-bit instructions. So immediates are still 16 bits. Only the register file, address and data buses are 64 bits. In any case, OR64 hasn't really been developed. Binutils is probably partway there (I tried to keep the cgen stuff as compatible with it as possible) but that's about it. -Pete
