    2020-02-18  Bill Schmidt  <wschmidt@linux.ibm.com>
    
    	* config/rs6000-builtin-new.def (ABS_V16QI): Remove abs	attribute.
            (ABS_V8HI): Likewise.
            * config/rs6000/rs6000-call.c (rs6000_expand_builtin): Handle
    	init, set, extract, and	pred attributes.
            * config/rs6000/rs6000-gen-builtins.c (Header commentary): Remove
    	abs attribute.
            (attrinfo): Likewise.
            (parse_bif_attrs): Likewise.
            (write_decls): Likewise.
            (write_init_bif_table):	Likewise.
