hi 

thanks for ur help.
 
I'm so sad that maybe ur repply sentenses my project--at least my early 
work--to death. What we plan to do is to design an new CPU architecture 
based on the DSP 
architecture, and we wish the CGEN & SID would help us to simulator ur  
design (including the ISA),before the real CPUis designed. So, we spent a 
lot of time on CGEN & SID. Limited by our knowledge on GNU, the work goes 
on slowly. Now it seems that our goal can not be achieved. :-( 

However, could we join u to develop the gcc? I mean, updating gcc and 
porting gcc to our target new CPU, so we can get a cross--complier, maybe 
we could write an RTL description for our target CPU. If so, what should we 
do and how to do?

thanks for all ur help.
