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

2649 VTABLE_INHERIT is a zero-space relocation used to describe to the
2650 linker the inheritence tree of a C++ virtual function table. The
2651 relocation's symbol should be the parent class' vtable, and the
2652 relocation should be located at the child vtable.
2654 VTABLE_ENTRY is a zero-space relocation that describes the use of a
2655 virtual function table entry. The reloc's symbol should refer to the
2656 table of the class mentioned in the code. Off of that base, an offset
2657 describes the entry that is being used. For Rela hosts, this offset
2658 is stored in the reloc's addend. For Rel hosts, we are forced to put
2659 this offset in the reloc's section offset. */
