craig.topper added a comment.

How much of the existing vector code in the backend including tablegen can be 
reused for 0.71? How much of the intrinsic interface can be used? 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.

How many people are going to maintain this other version?
