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. */

437 The CAT4 hack is to avoid a problem with some strict ANSI C preprocessors.
438 The problem is, "32_" is not a valid preprocessing token, and we don't
439 want extra underscores (e.g., "nlm_32_"). The XCAT2 macro will cause the
440 inner CAT macros to be evaluated first, producing still-valid pp-tokens.
441 Then the final concatenation can be done. (Sigh.) */

1653/* The Alpha LITERAL/LITUSE relocs are produced by a symbol reference;
1654the assembler turns it into a LDQ instruction to load the address of
1655the symbol, and then fills in a register in the real instruction.
1656
1657The LITERAL reloc, at the LDQ instruction, refers to the .lita
1658section symbol. The addend is ignored when writing, but is filled
1659in with the file's GP value on reading, for convenience, as with the
1660GPDISP_LO16 reloc.
1661
6b31fd3a
ILT
1662The ELF_LITERAL reloc is somewhere between 16_GOTOFF and GPDISP_LO16.
1663It should refer to the symbol to be referenced, as with 16_GOTOFF,
1664but it generates output not based on the position within the .got
1665section, but relative to the GP value chosen for the file during the
1666final link stage.
1667

KR
1668The LITUSE reloc, on the instruction using the loaded address, gives
1669information to the linker that it might be able to use to optimize
1670away some literal section references. The symbol is ignored (read
1671as the absolute section symbol), and the "addend" indicates the type
1672of instruction using the register:
16731 - "memory" fmt insn
16742 - byte-manipulation (byte offset reg)
16753 - jsr (target of branch)
1676
1677The GNU linker currently doesn't do any of this optimizing. */
