  dwarf.h   DWARF  debugging information values
  $Revision: 1.5 $    $Date: 05/05/25 10:54:11-07:00 $    

  The comment "DWARF3" appears where there are
  new entries from DWARF3, and other comments apply
  where extension entries appear.

  A few extension names have omitted the 'vendor id'
        (See chapter 7, "Vendor Extensibility"). Please
  always use a 'vendor id' string in extension names.

  Vendors should use a vendor string in names and
  whereever possible avoid duplicating values used by
  other vendor extensions
