Fixing this is important because aften is a dependency of jack.

[ryandesign (Ryan Carsten Schmidt)]

Unsurprisingly, this ten-year-old code only contains Intel and PowerPC implementations of apply_simd_restrictions.

[ryandesign (Ryan Carsten Schmidt)]

​Reported to the developers but I'm not optimistic that they still exist or care about this code.

[ryandesign (Ryan Carsten Schmidt)]

Has duplicate #62812.

The developers have not responded to my bug report. If anyone knows how to provide the missing arm64 code or work around it, please submit a pull request to us.
