If we’re talking about completely duplicating everything it is very unlikely we can accept it. RISCVGenDAGISel.inc, for example, is already significantly larger than any other target in tree. I don’t know how big it can get before it becomes an issue.

I will not submit RVV0.71 to the community, I just want to extend the interface to support multiple versions, this will help to solve the compatibility issue of different versions of the extension, this issue is common.
