    2020-09-01  Michael Meissner  <meissner@linux.ibm.com>
    
            * config/rs6000/pcrel-opt.c (pcrel_opt_load): Rename from
            do_pcrel_opt_load.
            (pcrel_opt_store): Rename from do_pcrel_opt_store.
            (pcrel_opt_address): Rename from do_pcrel_opt_addr.  Bump total
            number of external addresses here.  Update calls to pcrel_opt_load
            and pcrel_opt_store.
            (pcrel_opt_pass): Likewise.  Move update of counters into
            pcrel_opt_address.  Update pcrel_opt_address call.  Don't rebuild
            UD/DU chains at exit.
