I'm working on a code generator for the i860. Currently the code selection
phase picks scalar floating point instructions (f* rather than pf*) for
fp codes.

I wish now to have the cg generate pipelined versions of the instructions.
Should I do this in the code selection phase or is it better to select
scalar instruction as I've been doing and transform these into pipelined
versions in a later phase?

thanks, jason.
