commit 3901cdd34ce7d6c5258061c60a23a1fba3fbfe55
Author: Michael Meissner <meissner@linux.ibm.com>
Date:   Fri Mar 8 17:15:04 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.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.
