25/* bfd.h -- The only header file required by users of the bfd library
26
27The bfd.h file is generated from bfd-in.h and various .c files; if you
28change it, your changes will probably be lost.
29
30All the prototypes and definitions following the comment "THE FOLLOWING
31IS EXTRACTED FROM THE SOURCE" are extracted from the source files for
32BFD. If you change it, someone oneday will extract it from the source
33again, and your changes will be lost. To save yourself from this bind,
34change the definitions in the source in the bfd directory. Type "make
35docs" and then "make headers" in that directory, and magically this file
36will change to reflect your changes.
37
38If you don't have the tools to perform the extraction, then you are
39safe from someone on your system trampling over your header files.
40You should still maintain the equivalence between the source and this
41file though; every change you make to the .c file should be reflected
42here. */

1380
1381 The LITERAL reloc, at the LDQ instruction, refers to the .lita
1382 section symbol. The addend is ignored when writing, but is filled
1383 in with the file's GP value on reading, for convenience, as with the
1384 GPDISP_LO16 reloc.
1385
1386 The LITUSE reloc, on the instruction using the loaded address, gives
1387 information to the linker that it might be able to use to optimize
1388 away some literal section references. The symbol is ignored (read
1389 as the absolute section symbol), and the "addend" indicates the type
1390 of instruction using the register:
1391 1 - "memory" fmt insn
1392 2 - byte-manipulation (byte offset reg)
1393 3 - jsr (target of branch)
