Interesting,
I have essentially the same patch in my tree now I wanted to send for
review, but I did run into problems with explicit instantiations where
declaration is changed from DECL_EXTERNAL to not DECL_EXTERNAL after
calling cgraph_finalize. Did you solved this problem somehow?
Thanks for for the work! It was my TODO for a while (together with
avoiding the walk in lower_function now when it don't deal with other
stuff it did originally)
