commit aeb37fbc6a69d79ec80e5c7041fb084bd6a3fa67
Author: Michael Meissner <meiss...@linux.ibm.com>
Date: Thu Jan 16 12:22:08 2025 -0500
Change TARGET_MODULO to TARGET_POWER9.
This patch changes TARGET_MODULO to TARGET_POWER9. The -mmodulo switch is
not
being changed, just the name of the macros used to determine if the PowerPC
processor supports ISA 3.0 (Power9).
