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:

Plenty of room!
make sl and sr Opcode 101 and 110 respectively, and you can use
opcode#2 as the log-step variable

can do a Rot 127 (if possible) in 7 instructions using just one... and in 3 instructions using both? shiftRight:64 + shiftRight:64 + shiftLeft:1...
