commit 8f57958b33f5a9d0fdfd1057e1deb04eed29e35f
Author: Michael Meissner <meissner@linux.ibm.com>
Date:   Thu May 2 16:30:35 2024 -0400

    Add -mcpu=future tuning support.
    
    This patch makes -mtune=future use the same tuning decision as -mtune=power11.

    gcc/
    
            * config/rs6000/power10.md (all reservations): Add future as an
            alterntive to power10 and power11.
