252b5132
RH
28
29The bfd.h file is generated from bfd-in.h and various .c files; if you
30change it, your changes will probably be lost.
31
32All the prototypes and definitions following the comment "THE FOLLOWING
33IS EXTRACTED FROM THE SOURCE" are extracted from the source files for
34BFD. If you change it, someone oneday will extract it from the source
35again, and your changes will be lost. To save yourself from this bind,
36change the definitions in the source in the bfd directory. Type "make
37docs" and then "make headers" in that directory, and magically this file
38will change to reflect your changes.
39
40If you don't have the tools to perform the extraction, then you are
41safe from someone on your system trampling over your header files.
42You should still maintain the equivalence between the source and this
43file though; every change you make to the .c file should be reflected
44here. */

2006The ELF_LITERAL reloc is somewhere between 16_GOTOFF and GPDISP_LO16.
2007It should refer to the symbol to be referenced, as with 16_GOTOFF,
2008but it generates output not based on the position within the .got
2009section, but relative to the GP value chosen for the file during the
2010final link stage.
2011
2012The LITUSE reloc, on the instruction using the loaded address, gives
2013information to the linker that it might be able to use to optimize
2014away some literal section references. The symbol is ignored (read
2015as the absolute section symbol), and the "addend" indicates the type
2016of instruction using the register:
20171 - "memory" fmt insn
20182 - byte-manipulation (byte offset reg)
dfe57ca0 20193 - jsr (target of branch) */
