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

the symbol, and then fills in a register in the real instruction.
|

|
|
|
|
|
|

The LITERAL reloc, at the LDQ instruction, refers to the .lita
|
|
|

section symbol. The addend is ignored when writing, but is filled
|
|
|
|

GPDISP_LO16 reloc.

|
|
|
|
|
|
|
The ELF_LITERAL reloc is somewhere between 16_GOTOFF and GPDISP_LO16.
|
|
|
|
|
It should refer to the symbol to be referenced, as with 16_GOTOFF,
|
|
|
|
|
but it generates output not based on the position within the .got
|
|
|
|
|
section, but relative to the GP value chosen for the file during the

|
|
final link stage.
|
|
|
|
|
|
|
|
|
|
The LITUSE reloc, on the instruction using the loaded address, gives
|
|
|
|
|
information to the linker that it might be able to use to optimize
|
|
|
|
|
away some literal section references. The symbol is ignored (read
|
|
|
|
|
as the absolute section symbol), and the "addend" indicates the type
|
|
|
|
|
of instruction using the register:
|
|
|
|
|
1 - "memory" fmt insn
|
|
|
|
|
2 - byte-manipulation (byte offset reg)
|
|

|
3 - jsr (target of branch)
|
