Re: [gcc] RE: Porting GCC

Hello Siva,
Thanks for the fast response.

I read some articles about CGEN and Simn-ML which probably can help me
dealing with these files.
But I did not get them to work. Do you think  that  these tools are useful
for such purpose ?

About the document you have recommended. I have it, but it looks more like a
reference. And some parts of it are still incomplete for example RTL
section.

However, I started changing an existing machine description , but I can't
still get of my head that there must be some tools :)).

Regards Petar
