commit 31e9b8945f5b9261b0d3f0f95465a5092a470205
Author: Michael Meissner <meissner@linux.ibm.com>
Date:   Fri Mar 8 17:06:33 2024 -0500

    Add -mcpu=power11 support part 2
    
    This patch allows GCC to be configured with the --with-cpu=power11 and
    --with-tune=power11 options.
    
    This patch passes -mpwr11 to the assembler if the user uses -mcpu=power11.
    
    This patch adds support for using "power11" in the __builtin_cpu_is built-in
    function.
