Add new instruction in rocket core pipeline, not via RoCC

I am interested to know what's the effort to add new instruction support (e.g. ALU instructuon) in rocket core. Has anyone done it before and could share? I searched the web and forums and mostly they talked about extending instruction using accelerator core via RoCC. I am more interested in adding it in pipeline. Is there any hook in current code to make it easier?
Thanks in advance.
