I wasn't aware of cross unwinding, I think you are referring to [1]. Thanks for the pointer.

Would it make sense to support a libunwind build that only supports native unwinding? For baremetal (embedded) applications, I don't think cross unwinding (if I understand it correctly) makes a lot of sense.

Thanks!
