commit r14-270-g469b655b30dae58b41232b0dea5d1ccc072356a9
Author: David Edelsohn <dje.gcc@gmail.com>
Date:   Sun Apr 23 11:22:06 2023 -0400

    aix: Default AIX 7.2 to POWER7 server and AIX 7.3 to POWER8 server.
    
    AIX 7.2 minimum ISA is POWER7 and AIX 7.3 minimum ISA is POWER8.
    This patch changes the aix72.h configuration to POWER7 with VSX enabled
    by default (with the AIX VSX ABI limitations), matching LLVM on AIX,
    and changes the aix73.h configuration to POWER8.
    
    gcc/ChangeLog:
            * config/rs6000/aix72.h (TARGET_DEFAULT): Use ISA_2_6_MASKS_SERVER.
            * config/rs6000/aix73.h (TARGET_DEFAULT): Use ISA_2_7_MASKS_SERVER.
            (PROCESSOR_DEFAULT): Use PROCESSOR_POWER8.
