commit 66557e68965e1b2f97e80ee2c3a498131ccfbb77

    config/cris/cris.h (REVERSIBLE_CC_MODE): Define to true.
    
    For some reason (like a buglet in the user in jump.c), defining this makes
    a beneficial difference in ledf2, thus this is separated to its own commit.
    Also, add comment on (not defining) REVERSE_CONDITION.
    
    gcc:
            * config/cris/cris.h (REVERSIBLE_CC_MODE): Define to true.
