commit 8f57958b33f5a9d0fdfd1057e1deb04eed29e35f
Author: Michael Meissner <meiss...@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.
