commit 92eaf6de41f184d7e62624a2bd67cfc2aabf8a4e
Author: Michael Meissner <meissner@linux.ibm.com>
Date:   Thu Feb 15 15:05:47 2024 -0500

    Set future machine type in assembler if -mcpu=future
    
    This patch uses the .machine directive to tell the assembler to use any
    possible future instructions.
