In my mind, micro-code means that stuff that implements the instructions used
by compilers. Usually, the micro-code also have lots of strange encoding with
parallellism and limited to a small addressing range.

Since I don't know what a superscalar machine looks like, I really can't say
much about it. If your target architecture has "small" instructions that the
compiler must string together to do "big" operations, then you probably want
to get a RISC compiler.

Opinion? Did I say something in that posting? Wow! Please, can I let that
