--- Comment #44 from Jan Hubicka <hubicka at gcc dot gnu.org> --- Thanks, I am happy we now have real-world use of symver attribute. I have WIP patch for better control over the symbol visibility, but I have run into problems with gas limitations which was fixed by HJ about two weeks ago. I will try to update the patch and aim for backporting to gcc 10.2.
