GNU CC Compiler and machine register number

[Ben A. Abderrazek]

Dear Helper,


I have already installed GNU CC 2.7.3.2 compiler.

My quesstion is: 

First:

Is it possible for  the above compiler to generate a code for more than
32 architectural
registers (lets say 64 or 128 registers). The idea which I have, is that
I have to change the register numbers parameter 
in  the machine descrion code from 32  to 64 or 128.

Second: 

If it is right, is it  only the machine description file I have to
change? or there are other files  I have to change too.



I really need some hints,
Many thanks,


Ben,
