  27 /* bfd.h -- The only header file required by users of the bfd library
  28
  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.
  31
  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.
  39
  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
  44 here.  */

1993 The ELF_LITERAL reloc is somewhere between 16_GOTOFF and GPDISP_LO16.
1994 It should refer to the symbol to be referenced, as with 16_GOTOFF,
