Red Hat's stated reasoning seems to be that they want to reduce the burden of testing multiple code paths when older systems continue to be supported: https://developers.redhat.com/articles/2024/01/02/exploring-x86-64-v3-red-hat-enterprise-linux-10# "if RHEL 10 requires the x86-64-v3 baseline, ISVs will be able to rely on it, too. This reduces maintenance cost for some ISVs because they no longer need to maintain (and test) AVX and non-AVX code paths in their manually tuned software." -------------- next part -------------- An HTML attachment was scrubbed...
