Hello,
I am porting gcc to a target cpu containing multiple risc units
sharing the same register file.
I have read the gcc DFA manual, but I still cannot figure out how the
describe the pipeline.
Can I use DFA to describe this target cpu?
Thanks.
Mike

Yes.

Try looking at DFA descriptions that have been written for other
targets. There are some simple ones that aren't too hard to understand,
and you can learn a bit more about how this stuff works by looking at
some of them.
