Re: [arch-general] RFC: Use x86_64-v2 architecture

Hello, I have run the benchmarks and here are the results: https://openbenchmarking.org/result/2103142-HA-UARCHLEVE55 TL;DR: - there is no or negligible performance benefit of *-march=nehalem*, which corresponds to x86_64-v2, - there

Re: [arch-general] RFC: Use x86_64-v2 architecture

I am going to benchmark the performance difference between the various x86 uarch levels. I will be using Phoronix Test Suite, which has some support for performing compiler and compile flag benchmarks. I believe that for the purpose of this discussion that will be a waste of your time. There is

Hello, I am going to benchmark the performance difference between the various x86 uarch levels. I will be using Phoronix Test Suite, which has some support for performing compiler and compile flag benchmarks. I am opposed to dropping support for older CPUs, but I will perform this test fairly. Th
