In https://github.com/dotnet/performance, we have seen lot of MicroBenchmarks regress that often is the case of Intel's JCC erratum. As such, we wanted to see if we can mitigate it or add a switch in codegen to mitigate it for experimental purpose and performance comparison.
- As per an experiment conducted by Brian Robbins in JCC Erratum Impact on .NET Core · Issue #35730 · dotnet/runtime (github.com), the impact of JCC erratum is not on real world applications.
