    Phoronix: AMD Zen 2 "Znver2" Optimizations With LLVM Clang 10 Bring Some Improvements

    With LLVM Clang 10 having added a Zen 2 scheduler model tuned for the latest AMD CPUs over the existing "znver2" tuning that had just copied the Zen 1 scheduler, here are some benchmarks looking at the LLVM Clang 9 vs. 10 compiler performance on AMD EPYC when making use of "-march=znver2" optimizations...

    Zen 2 tuning is going to get better down the road as Sony's compiler engineers also did a lot of work on Jaguar upstream.

        Openssl regresion is fixed now (problem in openssl compile scripts).
        Michael can you use version with backported fix ?

          Can you compare ´znver2´ for clang vs gcc?

            Very cool, didn't know about that, glad to hear at least one console maker is upstreaming patches!
