26/* bfd.h -- The only header file required by users of the bfd library
27
28The bfd.h file is generated from bfd-in.h and various .c files; if you
29change it, your changes will probably be lost.
30
31All the prototypes and definitions following the comment "THE FOLLOWING
32IS EXTRACTED FROM THE SOURCE" are extracted from the source files for
33BFD. If you change it, someone oneday will extract it from the source
34again, and your changes will be lost. To save yourself from this bind,
35change the definitions in the source in the bfd directory. Type "make
36docs" and then "make headers" in that directory, and magically this file
37will change to reflect your changes.
38
39If you don't have the tools to perform the extraction, then you are
40safe from someone on your system trampling over your header files.
41You should still maintain the equivalence between the source and this
42file though; every change you make to the .c file should be reflected
43here. */

1887the assembler turns it into a LDQ instruction to load the address of
1888the symbol, and then fills in a register in the real instruction.
1889
1890The LITERAL reloc, at the LDQ instruction, refers to the .lita
1891section symbol. The addend is ignored when writing, but is filled
1892in with the file's GP value on reading, for convenience, as with the
1893GPDISP_LO16 reloc.
1894
1895The ELF_LITERAL reloc is somewhere between 16_GOTOFF and GPDISP_LO16.
1896It should refer to the symbol to be referenced, as with 16_GOTOFF,
1897but it generates output not based on the position within the .got
1898section, but relative to the GP value chosen for the file during the
1899final link stage.
1900
1901The LITUSE reloc, on the instruction using the loaded address, gives
1902information to the linker that it might be able to use to optimize
1903away some literal section references. The symbol is ignored (read
1904as the absolute section symbol), and the "addend" indicates the type
1905of instruction using the register:
19061 - "memory" fmt insn
19072 - byte-manipulation (byte offset reg)
19083 - jsr (target of branch)
