This looks fine to me based on your description of the issue and how the libgcc implementation achieves this. Someone else will need to sign off on this however.

I'll note that this implementation was upstreamed from FreeBSD, and at the moment we still allow occasional ABI breakage RISC-V where it is needed. I'm not aware of who else (if anyone) might be a consumer of this unwind implementation.
