I wonder if it might be a good time to bump the i686 minimal requirements for F24 to include sse2. Not for performance reasons, but for compatibility: almost all developers are on x86_64 these days and i686 is pretty much just limping along. If we include sse2 on i686, that removes another difference between x86_64 and i686 and makes things easier for us as a downstream. Apparently quite a few upstreams these days consider sse2 as a minimal requirement and it seems more and more that Fedora packagers need to work this around if we don't follow the lead. I don't think this is worth doing for performance reasons. I don't think a few percentage of possible gain in micro benchmarks is worth it, but if it saves some hundreds of hours of developer time for people who are working on Fedora and don't have to work around missing sse2, I'd say it's very well worth the cost of losing ancient CPU support. -- Kalev -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
