commit ab79e7eaa987f49a8148f672963016ceff03f1fd
Author: G. Branden Robinson <g.branden.robinson@gmail.com>
AuthorDate: Tue Jan 24 02:30:25 2023 -0600

    [mm]: Eliminate spew at high debug levels.
    
    * contrib/mm/m.tmac (df@print-float): Eliminate spew at high debug
      levels.  This macro gets called even when there aren't any floating
      displays pending, so we cannot assume that related registers are
      defined.
