To elaborate, there are two implementations of the `LiveDebugValues` pass, one for "old" DBG_VALUE instructions and the other for instruction referencing. I don't believe RISCV currently supports instruction referencing, thus there's no reason to pass `-force-instr-ref-livedebugvalues` to get coverage of both implementations -- you should be able to get away with deleting the RUN line.
