- Also, hand-coding something in assembler for a RISC chip is MUCH
- harder than on a traditional processor. There's a smaller instruction
- set, more registers, and you have to worry about pipelining. A good
- optimizing compiler can usually do a better job than most humans can
- do (at least in a reasonable amount of time).
