Re: Porting Binutils

[Dave Brolley <brolley at redhat dot com>]

Hi,

Generally one starts by cloning an existing port which is similar to the 
new one. I usually do this by copying all of the files and directories 
named after the port to be cloned and by grepping the remaining 
source/Makefiles/scripts for references to the old port and copying them 
to add the new port. This leaves you with a new port which behaves like 
the old one. I then start ripping out the details of the old port and 
replacing them with implementation of the new one.

There is some documentation in cgen/doc which may also be helpful for 
learning the scheme-like cgen .cpu language and how to generate source 
from the .cpu and .opc files for your port.

I hope this helps,
Dave
