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.
