commit bb0f198819a792a9a1a76046a63c58b84a3a586f
Author: Michael Meissner <meiss...@linux.ibm.com>
Date: Thu Jan 16 12:19:16 2025 -0500
Change TARGET_FPRND to TARGET_POWER5X.
This patch changes TARGET_POWER5X to TARGET_POWER5. The -mfprnd switch is
not
being changed, just the name of the macros used to determine if the PowerPC
processor supports ISA 2.4 (Power5x).

* gcc/config/rs6000/rs6000.cc (rs6000_option_override_internal):
Change TARGET_FPRND to TARGET_POWER5X.
* gcc/config/rs6000/rs6000.h (TARGET_POWERP5X): New macro.
* gcc/config/rs6000/rs6000.md (fmod<mode>3): Change TARGET_FPRND to
TARGET_POWER5X.
(remainder<mode>3): Likewise.
(fctiwuz_<mode): Likewise.
