ARM neon support.

[jianshu93]

Hello Daniel,

I saw some avx to neon support here: https://github.com/kunpengcompute/AvxToNeon https://github.com/DLTcollab/sse2neon

I did not check the exact types used for dashing2 but it seems it has included major types.

I only see avx2 and 512 supported binaries but not sse but it could also be helpful.

Thanks,

Jianshu

Hi Jianshu,

You're right - we can probably support all targets using simde. I'll get to work on it over the next few days, since it would be useful for it to run on non-x86 platforms.

Thanks!

Daniel
