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.
