> Hi please consider.
> 
> Added case to turn off UseZvfh when no RVV. 
> Which is the cause of the test issues, zvfh on but no rvv.
> 
> Also made all case identical and added no warning when default.
> Move them to the common init, as the "UseExtension" is not C2 specific.
> 
> Manual tested and some random compiler tests.

> Thanks, Robbin
