        * frv-sim.h (REGNUM_LR): Removed.
        (SPR_REGNUM_MIN,SPR_REGNUM_MAX): New macros.
        * frv.c (frvbf_fetch_register): Fetch SPR registers based on
        SPR_REGNUM_MIN and SPR_REGNUM_MAX. Check whether SPRs are implemented.
        Return 0 for an unimplemented register. Return the length of the data
        for an implemented register.
        (frvbf_store_register): Ditto.
