Hi, Pan

Any comments on this patch?

I think this patch is quite important, because RVV is completely unavailable on 
LTO at
present. In fact, I discovered this ICE while trying to compile some 
computational
libraries using LTO. Unfortunately, none of the libraries currently compile 
through
properly.
