commit ea0193ba078ba6d9747329266de9aa9b2a9bb5d5
Author: Michael Meissner <meissner@linux.ibm.com>
Date:   Fri Mar 8 23:26:03 2024 -0500

    Add -mcpu=future support part 2
    
    This patch allows GCC to be configured with the --with-cpu=future and
    --with-tune=future options.
    
    This patch passes -mfutue to the assembler if the user uses -mcpu=future.

            * config.gcc (rs6000*-*-*, powerpc*-*-*): Add support for power11.
            * config/rs6000/aix71.h (ASM_CPU_SPEC): Add support for -mcpu=power11.
            * config/rs6000/aix72.h (ASM_CPU_SPEC): Likewise.
            * config/rs6000/aix73.h (ASM_CPU_SPEC): Likewise.
            * config/rs6000/driver-rs6000.cc (asm_names): Likewise.
