        * regcache.c (read_register_bytes): Failing to set register_valid
        is not necessarily an error, if the register is a pseudo-register.
        Some pseudo-registers are never marked as valid, so that they will
        be read anew every time.  Determining if a pseudo-register is valid
        (or should be marked invalid) may be difficult, whereas just
        recomputing it may be cheap.
