simoncook updated this revision to Diff 205287.
simoncook added a comment.
- Refactored register tables to match style used in i386/x86_64
- Add enum for RISC-V DWARF numbers
- Add F registers (assuming 32-bit, at runtime this seems to be overwritten to
64-bit if D extension is provided)
- Add default unwind plan for first frame
