commit 63ecac63bac6f2c1e7e151a4ff494f27b41b86e7
Author: Michael Meissner <meiss...@linux.ibm.com>
Date: Mon Jul 29 23:15:10 2024 -0400
Make clone_targets use architecture flags.
This patch expands on the previous patch and changes the target_clones
support
to use an architecture mask instead of isa bits.

* config/rs6000/rs6000.cc (struct clone_map): Switch to use
architecture
flags instead of ISA flags for target_clone support.
(rs6000_clone_map): Likewise.
(rs6000_clone_priority): Likewise.
