I think we can all agree that there is very little benefit to duplicating every single library, so extra space usage would come only from libraries which meet all of: * Compiling with AVX2 (or whatever) provides benefit * Special runtime detection code isn't included * Function multiversioning or the fancy target_clones attribute isn't used And by implementing the latter two, the set can shrink.

I have a hard time believing that solving that would be somehow less preferable than either making Fedora unusable on a whole class of hardware or splitting off a completely new architecture. - J< _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org
