    2024-07-30  Michael Meissner  <meiss...@linux.ibm.com>
    
            * config/rs6000/rs6000-arch.def: Add support for 476, a2, and cell
            processors.
            * config/rs6000/rs6000-c.cc (rs6000_target_modify_macros): Use arch
            flags for power4, power5, and power6.
            * config/rs6000/rs6000.cc (get_arch_flags): Add 476, a2, and cell
            processors.
