26 /* bfd.h -- The only header file required by users of the bfd library
27
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.
30
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.
38
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
43 here. */

971 the symbol to it, and builds a relocation. To build the lists
972 of constructors, all the linker has to do is catenate all the

1922 section symbol. The addend is ignored when writing, but is filled
1923 in with the file's GP value on reading, for convenience, as with the
1924 GPDISP_LO16 reloc.
1925
1926 The ELF_LITERAL reloc is somewhere between 16_GOTOFF and GPDISP_LO16.
1927 It should refer to the symbol to be referenced, as with 16_GOTOFF,
1928 but it generates output not based on the position within the .got
1929 section, but relative to the GP value chosen for the file during the
1930 final link stage.
1931
1932 The LITUSE reloc, on the instruction using the loaded address, gives
1933 information to the linker that it might be able to use to optimize
1934 away some literal section references. The symbol is ignored (read
1935 as the absolute section symbol), and the "addend" indicates the type
1936 of instruction using the register:
1937 1 - "memory" fmt insn
1938 2 - byte-manipulation (byte offset reg)
1939 3 - jsr (target of branch)
1940
