            Bug ID: 245024
           Summary: elftoolchain objcopy is missing --add-symbol
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bin
          Assignee: bugs at FreeBSD.org
          Reporter: markj at FreeBSD.org

The objcopy from GNU binutils implements --add-symbol:

==
--add-symbol name=[section:]value[,flags]

    Add a new symbol named name while copying the file. This option may be
specified multiple times. If the section is given, the symbol will be
associated with and relative to that section, otherwise it will be an ABS
symbol. Specifying an undefined section will result in a fatal error. There is
no check for the value, it will be taken as specified. Symbol flags can be
specified and not all flags will be meaningful for all object file formats. By
default, the symbol will be global. The special flag ’before=othersym’ will
insert the new symbol in front of the specified othersym, otherwise the
symbol(s) will be added at the end of the symbol table in the order they
appear.
==

elftoolchain objcopy does not.  I noticed because it would have been useful for
a project I'm working on; I haven't seen a case where the lack of compatibility
is a problem.
