Re: [PATCH] x86: add more x86-64 micro-architecture levels

[WangYuli]

Yes, specifying '-march=x86-64-v3' can indeed yield significant performance improvements for CPUs that support it. I could confirm this.

Please allow me a few days, as I will provide a detailed test data report from my own tests after my vacation.

Given that such submissions 'pop up' in the mailing list from time to time, I hope this time we can see it through.

We should have a broad discussion, comprehensive testing and a calm judgment until we reach a final conclusion on whether this modification brings more benefits or drawbacks.
