You want one ? ;-)

I think, I have some idea that can be useful for an human assembler, but not 
for a GCC backend. (macro, dependency detection, code coherency).

... That not the same problem, in one case we need VHDL coder and a final 
version of the FC0, and in the other case we need C coder with the manual...
If we respect the manual, we can do something useful before we have the FC0.
