-// darwinSupportsAVX512 checks Darwin kernel for AVX512 support via sysctl
-// call (see issue 43089). It also restricts AVX512 support for Darwin to
-// kernel version 21.3.0 (MacOS 12.2.0) or later (see issue 49233).
-//
-// Background:
-// Darwin implements a special mechanism to economize on thread state when
-// AVX512 specific registers are not in use. This scheme minimizes state when
-// preempting threads that haven't yet used any AVX512 instructions, but adds
-// special requirements to check for AVX512 hardware support at runtime (e.g.
-// via sysctl call or commpage inspection). See issue 43089 and link below for
-// full background:
-// https://github.com/apple-oss-distributions/xnu/blob/xnu-11215.1.10/osfmk/i386/fpu.c#L214-L240
-//
-// Additionally, all versions of the Darwin kernel from 19.6.0 through 21.2.0
-// (corresponding to MacOS 10.15.6 - 12.1) have a bug that can cause corruption
-// of the AVX512 mask registers (K0-K7) upon signal return. For this reason
-// AVX512 is considered unsafe to use on Darwin for kernel versions prior to
-// 21.3.0, where a fix has been confirmed. See issue 49233 for full background.
