Cyrix chip code generation

We are having a good time with the new Cyrix FasMath 83d87 plug-in
replacement for the 80387. It's pretty fast. It would be even faster
if we could generate code which would take full advantage of it, as
opposed to just 80387 code. Note that this code would be expected to
run on 80387 chips also, but perhaps not optimally.

1. Is this really actually possible (optimal code for 83D87 which
doesn't break the 80387). It would seem so.

2. Is there any plan for a compiler to generate such code? Language
is not the main issue, but code generation is. 

(There is interest, but somewhat less excited interest, in the code
generation for the II2 80287/80387 replacements.)

Thanks in advance.
