Description
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)
