Oh yes. This seems to me a far better idea than starting to write asm
code for specific (or a set of) processors.
Richard, giving that you have the skills (and seems that you have them),
it will be much better if you help writing a better C compiler (no jokes)
squeezing from egcs (here I admit I am using it ... but it works okay so
far if I use it at -O2 optimization level) the best assembly you can from
such a beast (hehe ... trying to get that 10 times speedup on C compiled
code ... I know ... maybe just a dream :)

Ciao,
Riccardo.
