    target/openrisc: Tidy ppc/npc implementation · 24c32852
    Richard Henderson authored
    The NPC SPR is really only supposed to be used for FPGA debugging.
    It contains the same contents as PC, unless one plays games.  Follow
    the or1ksim implementation in flushing delayed branch state when it
    is changed.
    The PPC SPR need not be updated every instruction, merely when we
    exit the TB or attempt to read its contents.
