commit c87c9fa6ccf75da5ddf2b774e7f40bec244a9bdc
Author: Michael Meissner <meiss...@linux.ibm.com>
Date: Fri Mar 8 23:52:28 2024 -0500
Add -mcpu=power11 tests.
This patch adds some simple tests for -mcpu=power11 support. In order to
run
these tests, you need an assembler that supports the -mpwr11 option.

gcc/testsuite/
* gcc.target/powerpc/power11-1.c: New test.
* gcc.target/powerpc/power11-2.c: Likewise.
* gcc.target/powerpc/power11-3.c: Likewise.
* lib/target-supports.exp (check_effective_target_power11_ok): Add
new
effective target.
