Not yet, there is only an x86_64 JIT right now. But an ARM64 (AArch64?) JIT would certainly be welcome.

Just a comment that I'm going to be working on an Arm64 JIT for this over the next couple of weeks, and will send PRs as I go along.

PR #99 is a draft PR which implements an ARM64 JIT.

@matt-gretton-dann Thanks for the work, PR #99 looks to be a good start for AArch64 JIT support, I tested it locally, passed uBPF builtin tests. Hope this could be merged.
Meanwhile, I kind of feel the string relocation and jump relocation could be unified and could share common data structure, this perhaps applies to both x86 and aarch64 backend and might be worth some follow up patches

Closing this as the aarch64 JIT is now implemented and tested in CI/CD.
