    S390: Guard RISBG usage with facility check · c2791380
    joransiu authored
    A use of risbg instruction is not guarded by the corresponding
    GENERAL_INSTR_EXT facility check.  This will result in an illegal
    instruction when running on hardware without that facility installed
    (i.e. z9).
