    Since the patent on the unaligned load/store instructions expired, is there any plan on adding them?

    I thought it would be handy to have for completeness. If it is too difficult, I do understand. I'll try taking a whack at it and see how far I get.......

    Implementing the unaligned load/store instructions efficiently isn't trivial since it could require two passes through the ALU which no other instructions currently require. It has been possible to avoid the instruction. I don't currently have any plans to add them. Are the instructions really needed?
