--- Comment #3 from Palmer Dabbelt <palmer at dabbelt dot com> --- Thanks for looking at this. If there's anything I can do to help feel free to ask, but from my understand this isn't a RISC-V backend problem so I'm not going to put this on my TODO list unless something changes (or someone corrects me).
