    [PATCH 30/61] MSA: Make MSA and microMIPS R5 unsupported
    
    There are no platforms nor simulators for MSA and microMIPS R5 so
    turning off this support for now.
    
    gcc/ChangeLog:
    
            * config/mips/mips.cc (mips_option_override): Error out for
            -mmicromips -mmsa.
