Help making eedi3m aarch64 compatible

[groucho86]

Hoping someone is able to find a way to make eedi3m work on M1/M2/M3 Macs:

The plugin uses x86-specific optimization via vectorclass, causing compilation to fail on aarch64.

sse2neon sounds like an option (albeit sub-optimal. cf: https://github.com/vapoursynth/vapoursynth/issues/516 )

I'm currently rewriting the plugin in Zig, so it will be possible to do a native aarch64 build.
But as I'm also changing the way processing is done (horizontal enlargement by default) to avoid temporary copies and gain a little performance, it's taking me a while to figure out what needs to be changed.

Bit of an aside, but are you willing and able to test plugins on Mac aarch64, groucho?

Similar to Julek, I’m also developing plugins in Zig, but I don’t have a Mac M1/2/3 to test things on.

[groucho86]

Yes I have an M2. Limited free time/availability but happy to help the community as much as possible.

Only opencl part ported. You can also check my github profile for more arm ported plugins (almost all ported with simd acceleration).
