RISC

/prog/, I'm working on a RISC instruction set that is more RISC than any RISC out there. I've devised an instruction format, plus fifteen core instructions that should suffice for any programming out there. The instruction format, instruction forms, and instructions can be found here:

Any comments or suggestions?

You could use three opcode bits to make an 8-bit immediate and have the instruction shift the register left by 8 bits before loading the immediate into the lower 8 bits. That way 8 instructions is the maximum needed to load any 64-bit value instead of 25 (3 per byte+1 for shift count) like before.
