OK. I will.

And about infrun code, without the arch support. It will break,right?

What about add a check for "frame_unwind_caller_id" in infrun? If it
got something wrong or arch don't support it. Use the way in
http://sourceware.org/ml/gdb-patches/2009-07/msg00182.html to handle
it.

Then we will not worry about the arch doesn't have unwinder.

What do you think about it?

Thanks,
