Re: M1 CPU features

In addition to SIMDe, projects like Blender are using sse2neon to allow them to compile Blender on arm64 while using libraries that use Intel intrinsics and haven't been ported for use with Arm Neon. https://github.com/DLTcollab/sse2neon I plan to package sse2neon after I update a couple of the

Re: M1 CPU features

And this article describes SIMDe: https://simd-everywhere.github.io/blog/2020/06/22/transitioning-to-arm-with-simde.html SIMD Everywhere (SIMDe) provides fast, portable, permissively-licensed (MIT) implementations of the x86 APIs which allow you to run code designed for x86/x86_64

Can someone who owns an M1 Mac run the following command and let me know what the output is? sysctl machdep.cpu.brand_string ; sysctl machdep.cpu | grep -i "avx\|sse" -- Jason Liu
