39 * These structures define an interface between core files and the debugger.
40 * Never change or delete any elements. If you add elements, add them to
41 * the end of the structure, and increment the value of its version field.
42 * This will help to ensure that today's core dump will still be usable
43 * with next year's debugger.
45 * A lot more things should be added to these structures. At present,
46 * they contain the absolute bare minimum required to allow GDB to work
47 * with ELF core dumps.
51 * The parenthsized numbers like (1) indicate the minimum version number
52 * for which each element exists in the structure. The version number is
53 * not bumped when adding new fields to the end, only if the meaning of
54 * an existing field changes. Additional fields are annotated as (1a),
55 * (1b), etc. to indicate the groupings of additions.
