@section Relocations
|
|
BFD maintains relocations in much the same way it maintains
|
|
symbols: they are left alone until required, then read in
|
|
en-masse and translated into an internal form. A common
|
|
routine @code{bfd_perform_relocation} acts upon the
|
|
canonical form to do the fixup.
|
|
|
|
Relocations are maintained on a per section basis,
|
|
while symbols are maintained on a per BFD basis.
|
|
|
|
All that a back end has to do to fit the BFD interface is to create
|
|
a @code{struct reloc_cache_entry} for each relocation
|
|
in a particular section, and fill in the right bits of the structures.

@strong{Description}@*
|
|
Here is a description of each of the fields within an @code{arelent}:
|
|
|
|
@itemize @bullet
|
|
|
|
@item
|
|
@code{sym_ptr_ptr}
|
|
@end itemize
|
|
The symbol table pointer points to a pointer to the symbol
|
|
associated with the relocation request. It is
|
|
the pointer into the table returned by the back end's
|
|
@code{get_symtab} action. @xref{Symbols}. The symbol is referenced
|
|
through a pointer to a pointer so that tools like the linker
|
|
can fix up all the symbols of the same name by modifying only
|
|
one pointer. The relocation routine looks in the symbol and
|
|
uses the base of the section the symbol is attached to and the
|
|
value of the symbol as the initial relocation offset. If the
|
|
symbol pointer is zero, then the section provided is looked up.
|
|
|
|
@itemize @bullet
|
|
|
|
@item
|
|
@code{address}
|
|
@end itemize
|
|
The @code{address} field gives the offset in bytes from the base of
|
|
the section data which owns the relocation record to the first
|
|
byte of relocatable information. The actual data relocated
|
|
will be relative to this point; for example, a relocation
|
|
type which modifies the bottom two bytes of a four byte word
|
|
would not touch the first byte pointed to in a big endian
|
|
world.
|
|
|
|
@itemize @bullet
|
|
|
|
@item
|
|
@code{addend}
|
|
@end itemize
|
|
The @code{addend} is a value provided by the back end to be added (!)
|
|
to the relocation offset. Its interpretation is dependent upon
|
|
the howto. For example, on the 68k the code:
|
|
|
|
@example
|
|
char foo[];
|
|
main()
|
|
@{
|
|
return foo[0x12345678];
|
|
@}
|
|
@end example
|
|
|
|
Could be compiled into:
|
|
|
|
@example
|
|
linkw fp,#-4
|
|
moveb @@#12345678,d0
|
|
extbl d0
|
|
unlk fp
|
|
rts
|
|
@end example
|
|
|
|
This could create a reloc pointing to @code{foo}, but leave the
|
|
offset in the data, something like:
|
|
|
|
@example
|
|
RELOCATION RECORDS FOR [.text]:
|
|
offset type value
|
|
00000006 32 _foo
|
|
|
|
00000000 4e56 fffc ; linkw fp,#-4
|
|
00000004 1039 1234 5678 ; moveb @@#12345678,d0
|
|
0000000a 49c0 ; extbl d0
|
|
0000000c 4e5e ; unlk fp
|
|
0000000e 4e75 ; rts
|
|
@end example
|
|
|
|
Using coff and an 88k, some instructions don't have enough
|
|
space in them to represent the full address range, and
|
|
pointers have to be loaded in two parts. So you'd get something like:
|
|
|
|
@example
|
|
or.u r13,r0,hi16(_foo+0x12345678)
|
|
ld.b r2,r13,lo16(_foo+0x12345678)
|
|
jmp r1
|
|
@end example
|
|
|
|
This should create two relocs, both pointing to @code{_foo}, and with
|
|
0x12340000 in their addend field. The data would consist of:
|
|
|
|
@example
|
|
RELOCATION RECORDS FOR [.text]:
|
|
offset type value
|
|
00000002 HVRT16 _foo+0x12340000
|
|
00000006 LVRT16 _foo+0x12340000
|
|
|
|
00000000 5da05678 ; or.u r13,r0,0x5678
|
|
00000004 1c4d5678 ; ld.b r2,r13,0x5678
|
|
00000008 f400c001 ; jmp r1
|
|
@end example
|
|
|
|
The relocation routine digs out the value from the data, adds
|
|
it to the addend to get the original offset, and then adds the
|
|
value of @code{_foo}. Note that all 32 bits have to be kept around
|
|
somewhere, to cope with carry from bit 15 to bit 16.
|
|
|
|
One further example is the sparc and the a.out format. The
|
|
sparc has a similar problem to the 88k, in that some
|
|
instructions don't have room for an entire offset, but on the
|
|
sparc the parts are created in odd sized lumps. The designers of
|
|
the a.out format chose to not use the data within the section
|
|
for storing part of the offset; all the offset is kept within
|
|
the reloc. Anything in the data should be ignored.
|
|
|
|
@example
|
|
save %sp,-112,%sp
|
|
sethi %hi(_foo+0x12345678),%g2
|
|
ldsb [%g2+%lo(_foo+0x12345678)],%i0
|
|
ret
|
|
restore
|
|
@end example
|
|
|
|
Both relocs contain a pointer to @code{foo}, and the offsets
|
|
contain junk.
|
|
|
|
@example
|
|
RELOCATION RECORDS FOR [.text]:
|
|
offset type value
|
|
00000004 HI22 _foo+0x12345678
|
|
00000008 LO10 _foo+0x12345678
|
|
|
|
00000000 9de3bf90 ; save %sp,-112,%sp
|
|
00000004 05000000 ; sethi %hi(_foo+0),%g2
|
|
00000008 f048a000 ; ldsb [%g2+%lo(_foo+0)],%i0
|
|
0000000c 81c7e008 ; ret
|
|
00000010 81e80000 ; restore
|

@end example

|
@itemize @bullet
|
|
|
|
@item
|
|
@code{howto}
|
|
@end itemize
|
|
The @code{howto} field can be imagined as a
|
|
relocation instruction. It is a pointer to a structure which
|
|
contains information on what to do with all of the other
|
|
information in the reloc record and data section. A back end
|
|
would normally have a relocation instruction set and turn
|
|
relocations into pointers to the correct structure on input -
|
|
but it would be possible to create each howto field on demand.
|
|
|
|
@subsubsection @code{enum complain_overflow}
|
|
Indicates what sort of overflow checking should be done when
|
|
performing a relocation.
|

@subsubsection @code{reloc_howto_type}

If @var{output_bfd} is supplied to this function, the

copied to the output file after they have been changed to

|
reflect the new state of the world. There are two ways of
|
|
reflecting the results of partial linkage in an output file:
|
|
by modifying the output data in place, and by modifying the
|
|
relocation record. Some native formats (e.g., basic a.out and
|
|
basic coff) have no way of specifying an addend in the
|
|
relocation type, so the addend has to go in the output data.
|
|
This is no big deal since in these formats the output data
|
|
slot will always be big enough for the addend. Complex reloc
|
|
types with addends were invented to solve just this problem.
|
|
The @var{error_message} argument is set to an error message if

Pass one of these values to @code{bfd_reloc_type_lookup}, and it'll

These PC-relative relocations are stored as word displacements --
|
|
i.e., byte displacements shifted right two bits. The 30-bit word
|
|
displacement (<<32_PCREL_S2>> -- 32 bits, shifted 2) is used on the
|
|
SPARC. (SPARC tools generally refer to this as <<WDISP30>>.) The
|
|
signed 16-bit displacement is used on the MIPS, and the 23-bit
|
|
displacement is used on the Alpha.

@deffn {} BFD_RELOC_ALPHA_GPDISP_HI16
|
|
Alpha ECOFF and ELF relocations. Some of these treat the symbol or
|
|
"addend" in some special way.
|
|
For GPDISP_HI16 ("gpdisp") relocations, the symbol is ignored when
|
|
writing; when reading, it will be the absolute section symbol. The
|
|
addend is the displacement in bytes of the "lda" instruction from
|
|
the "ldah" instruction (which is at the address of this reloc).
|
|
@end deffn
|
|
@deffn {} BFD_RELOC_ALPHA_GPDISP_LO16
|
|
For GPDISP_LO16 ("ignore") relocations, the symbol is handled as
|
|
with GPDISP_HI16 relocs. The addend is ignored when writing the
|
|
relocations out, and is filled in with the file's GP value on
|
|
reading, for convenience.
|
|
@end deffn
|
|
@deffn {} BFD_RELOC_ALPHA_GPDISP
|
|
The ELF GPDISP relocation is exactly the same as the GPDISP_HI16
|
|
relocation except that there is no accompanying GPDISP_LO16
|
|
relocation.
|

@end deffn

@deffn {} BFD_RELOC_ALPHA_LITERAL
|
|
@deffnx {} BFD_RELOC_ALPHA_ELF_LITERAL
|
|
@deffnx {} BFD_RELOC_ALPHA_LITUSE
|
|
The Alpha LITERAL/LITUSE relocs are produced by a symbol reference;
|
|
the assembler turns it into a LDQ instruction to load the address of
|
|
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
|
|
in with the file's GP value on reading, for convenience, as with the
|
|
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)
|
|
@end deffn
|
|
@deffn {} BFD_RELOC_ALPHA_HINT
|
|
The HINT relocation indicates a value that should be filled into the
|
|
"hint" field of a jmp/jsr/ret instruction, for possible branch-
|
|
prediction logic which may be provided on some processors.
|
|
@end deffn
|
|
@deffn {} BFD_RELOC_ALPHA_LINKAGE

@deffn {} BFD_RELOC_ALPHA_CODEADDR

|
|
These two relocations are used by the linker to determine which of
|
|
the entries in a C++ virtual function table are actually used. When
|
|
the --gc-sections option is given, the linker will zero out the entries
|
|
that are not used, so that the code for those functions need not be
|
|
included in the output.
|
|
|
|
VTABLE_INHERIT is a zero-space relocation used to describe to the
|
|
linker the inheritence tree of a C++ virtual function table. The
|
|
relocation's symbol should be the parent class' vtable, and the
|
|
relocation should be located at the child vtable.
|
|
|
|
VTABLE_ENTRY is a zero-space relocation that describes the use of a
|
|
virtual function table entry. The reloc's symbol should refer to the
|
|
table of the class mentioned in the code. Off of that base, an offset
|
|
describes the entry that is being used. For Rela hosts, this offset
|
|
is stored in the reloc's addend. For Rel hosts, we are forced to put
|
|
this offset in the reloc's section offset.
