26 /* bfd.h -- The only header file required by users of the bfd library
28 The bfd.h file is generated from bfd-in.h and various .c files; if you
29 change it, your changes will probably be lost.
31 All the prototypes and definitions following the comment "THE FOLLOWING
32 IS EXTRACTED FROM THE SOURCE" are extracted from the source files for
33 BFD. If you change it, someone oneday will extract it from the source
34 again, and your changes will be lost. To save yourself from this bind,
35 change the definitions in the source in the bfd directory. Type "make
36 docs" and then "make headers" in that directory, and magically this file
37 will change to reflect your changes.
39 If you don't have the tools to perform the extraction, then you are
40 safe from someone on your system trampling over your header files.
41 You should still maintain the equivalence between the source and this
42 file though; every change you make to the .c file should be reflected

2204 relocation should be located at the child vtable.
2206 VTABLE_ENTRY is a zero-space relocation that describes the use of a
2207 virtual function table entry. The reloc's symbol should refer to the
2208 table of the class mentioned in the code. Off of that base, an offset
2209 describes the entry that is being used. For Rela hosts, this offset
2210 is stored in the reloc's addend. For Rel hosts, we are forced to put
