And the OPTION_MASK_P8_FUSION mask is set here:

  /* Enable power8 fusion if we are tuning for power8, even if we aren't
     generating power8 instructions.  Power9 does not optimize power8 fusion
     cases.  */
  if (!(rs6000_isa_flags_explicit & OPTION_MASK_P8_FUSION))
    {
      if (processor_target_table[tune_index].processor == PROCESSOR_POWER8)
        rs6000_isa_flags |= OPTION_MASK_P8_FUSION;
      else
        rs6000_isa_flags &= ~OPTION_MASK_P8_FUSION;
    }
