Comment:

Polars recently dropped support for old CPUs in the default build (pola-rs/polars#11351) and now additionally requires:

  • BMI1/2
  • LZCNT
  • AVX2

I wonder if we should do the same.

  • BMI1/2 and LZCNT: Supported since Haswell (2013).
  • AVX2: Support since Haswell in Intel processors, and since Zen in AMD processors (2017)
