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 <<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 <<struct reloc_cache_entry>> for each relocation
|
|
in a particular section, and fill in the right bits of the structures.

DESCRIPTION
|
|
|
|
Here is a description of each of the fields within an <<arelent>>:
|
|
|
|
o <<sym_ptr_ptr>>
|
|
|
|
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
|
|
<<canonicalize_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.
|
|
|
|
o <<address>>
|
|
|
|
The <<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.
|
|
|
|
o <<addend>>
|
|
|
|
The <<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:
|
|
|
|
| char foo[];
|
|
| main()
|
|
| {
|
|
| return foo[0x12345678];
|
|
| }
|
|
|
|
Could be compiled into:
|
|
|
|
| linkw fp,#-4
|
|
| moveb @@#12345678,d0
|
|
| extbl d0
|
|
| unlk fp
|
|
| rts
|
|
|
|
This could create a reloc pointing to <<foo>>, but leave the
|
|
offset in the data, something like:
|
|
|
|
|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
|
|
|
|
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:
|
|
|
|
| or.u r13,r0,hi16(_foo+0x12345678)
|
|
| ld.b r2,r13,lo16(_foo+0x12345678)
|
|
| jmp r1
|
|
|
|
This should create two relocs, both pointing to <<_foo>>, and with
|
|
0x12340000 in their addend field. The data would consist of:
|
|
|
|
|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
|
|
|
|
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 <<_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.
|
|
|
|
| save %sp,-112,%sp
|
|
| sethi %hi(_foo+0x12345678),%g2
|
|
| ldsb [%g2+%lo(_foo+0x12345678)],%i0
|
|
| ret
|
|
| restore
|
|
|
|
Both relocs contain a pointer to <<foo>>, and the offsets
|
|
contain junk.
|
|
|
|
|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
|
|
|
|
o <<howto>>
|
|
|
|
The <<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.

FUNCTION

SYNOPSIS

|
(bfd *abfd,

|
|
|
|
DESCRIPTION
|
|
If @var{output_bfd} is supplied to this function, the
|
|
generated image will be relocatable; the relocations are
|
|
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
|
|
this return @code{bfd_reloc_dangerous}.

We start by subtracting the address of the section containing

the location.
|
|
|
|
If pcrel_offset is set, we must further subtract the position
|
|
of the location within the section. Some targets arrange for

|
the addend to be the negative of the position of the location
|
|
within the section; for example, i386-aout does this. For
|
|
i386-aout, pcrel_offset is FALSE. Some other targets do not

|
include the position of the location; for example, m88kbcs,

|
or ELF. For those targets, pcrel_offset is TRUE.
|
|
|
|
If we are producing relocatable output, then we must ensure

|
that this reloc will be correctly computed when the final
|
|
relocation is done. If pcrel_offset is FALSE we want to wind
|
|
up with the negative of the location within the section,
|
|
which means we must adjust the existing addend by the change

|
in the location within the section. If pcrel_offset is TRUE

we do not want to adjust the existing addend at all.

producing relocatable output it is not what the code

|
|
|
|
However, Ian wrote the following, regarding removing the line below,
|
|
which explains why it is still enabled: --djm
|
|
|
|
If you put a patch like that into BFD you need to check all the COFF
|
|
linkers. I am fairly certain that patch will break coff-i386 (e.g.,
|
|
SCO); see coff_i386_reloc in coff-i386.c where I worked around the
|
|
problem in a different way. There may very well be a reason that the
|
|
code works as it does.
|
|
|
|
Hmmm. The first obvious point is that bfd_perform_relocation should
|
|
not have any tests that depend upon the flavour. It's seem like
|
|
entirely the wrong place for such a thing. The second obvious point
|
|
is that the current code ignores the reloc addend when producing
|
|
relocatable output for COFF. That's peculiar. In fact, I really
|
|
have no idea what the point of the line you want to remove is.
|
|
|
|
A typical COFF reloc subtracts the old value of the symbol and adds in
|
|
the new value to the location in the object file (if it's a pc
|
|
relative reloc it adds the difference between the symbol value and the
|
|
location). When relocating we need to preserve that property.
|
|
|
|
BFD handles this by setting the addend to the negative of the old
|
|
value of the symbol. Unfortunately it handles common symbols in a
|
|
non-standard way (it doesn't subtract the old value) but that's a
|
|
different story (we can't change it without losing backward
|
|
compatibility with old object files) (coff-i386 does subtract the old
|
|
value, to be compatible with existing coff-i386 targets, like SCO).
|
|
|
|
So everything works fine when not producing relocatable output. When
|
|
we are producing relocatable output, logically we should do exactly
|
|
what we do when not producing relocatable output. Therefore, your
|
|
patch is correct. In fact, it should probably always just set
|
|
reloc_entry->addend to 0 for all cases, since it is, in fact, going to
|
|
add the value into the object file. This won't hurt the COFF code,
|
|
which doesn't use the addend; I'm not sure what it will do to other
|
|
formats (the thing to check for would be whether any formats both use
|
|
the addend and set partial_inplace).
|
|
|
|
When I wanted to make coff-i386 produce relocatable output, I ran
|
|
into the problem that you are running into: I wanted to remove that
|
|
line. Rather than risk it, I made the coff-i386 relocs use a special
|
|
function; it's coff_i386_reloc in coff-i386.c. The function
|
|
specifically adds the addend field into the object file, knowing that
|
|
bfd_perform_relocation is not going to. If you remove that line, then
|
|
coff-i386.c will wind up adding the addend field in twice. It's
|
|
trivial to fix; it just needs to be done.
|
|
|
|
The problem with removing the line is just that it may break some
|
|
working code. With BFD it's hard to be sure of anything. The right
|
|
way to deal with this is simply to build and test at least all the
|
|
supported COFF targets. It should be straightforward if time and disk
|
|
space consuming. For each target:
|
|
1) build the linker
|
|
2) generate some executable, and link it using -r (I would
|
|
probably use paranoia.o and link against newlib/libc.a, which
|
|
for all the supported targets would be available in
|
|
/usr/cygnus/progressive/H-host/target/lib/libc.a).
|
|
3) make the change to reloc.c
|
|
4) rebuild the linker
|
|
5) repeat step 2
|
|
6) if the resulting object files are the same, you have at least
|
|
made it no worse
|
|
7) if they are different you have to figure out which version is
|
|
right

However, Ian wrote the following, regarding removing the line below,
|
|
which explains why it is still enabled: --djm
|
|
|
|
If you put a patch like that into BFD you need to check all the COFF
|
|
linkers. I am fairly certain that patch will break coff-i386 (e.g.,
|
|
SCO); see coff_i386_reloc in coff-i386.c where I worked around the
|
|
problem in a different way. There may very well be a reason that the
|
|
code works as it does.
|
|
|
|
Hmmm. The first obvious point is that bfd_install_relocation should
|
|
not have any tests that depend upon the flavour. It's seem like
|
|
entirely the wrong place for such a thing. The second obvious point
|
|
is that the current code ignores the reloc addend when producing
|
|
relocatable output for COFF. That's peculiar. In fact, I really
|
|
have no idea what the point of the line you want to remove is.
|
|
|
|
A typical COFF reloc subtracts the old value of the symbol and adds in
|
|
the new value to the location in the object file (if it's a pc
|
|
relative reloc it adds the difference between the symbol value and the
|
|
location). When relocating we need to preserve that property.
|
|
|
|
BFD handles this by setting the addend to the negative of the old
|
|
value of the symbol. Unfortunately it handles common symbols in a
|
|
non-standard way (it doesn't subtract the old value) but that's a
|
|
different story (we can't change it without losing backward
|
|
compatibility with old object files) (coff-i386 does subtract the old
|
|
value, to be compatible with existing coff-i386 targets, like SCO).
|
|
|
|
So everything works fine when not producing relocatable output. When
|
|
we are producing relocatable output, logically we should do exactly
|
|
what we do when not producing relocatable output. Therefore, your
|
|
patch is correct. In fact, it should probably always just set
|
|
reloc_entry->addend to 0 for all cases, since it is, in fact, going to
|
|
add the value into the object file. This won't hurt the COFF code,
|
|
which doesn't use the addend; I'm not sure what it will do to other
|
|
formats (the thing to check for would be whether any formats both use
|
|
the addend and set partial_inplace).
|
|
|
|
When I wanted to make coff-i386 produce relocatable output, I ran
|
|
into the problem that you are running into: I wanted to remove that
|
|
line. Rather than risk it, I made the coff-i386 relocs use a special
|
|
function; it's coff_i386_reloc in coff-i386.c. The function
|
|
specifically adds the addend field into the object file, knowing that
|
|
bfd_install_relocation is not going to. If you remove that line, then
|
|
coff-i386.c will wind up adding the addend field in twice. It's
|
|
trivial to fix; it just needs to be done.
|
|
|
|
The problem with removing the line is just that it may break some
|
|
working code. With BFD it's hard to be sure of anything. The right
|
|
way to deal with this is simply to build and test at least all the
|
|
supported COFF targets. It should be straightforward if time and disk
|
|
space consuming. For each target:
|
|
1) build the linker
|
|
2) generate some executable, and link it using -r (I would
|
|
probably use paranoia.o and link against newlib/libc.a, which
|
|
for all the supported targets would be available in
|
|
/usr/cygnus/progressive/H-host/target/lib/libc.a).
|
|
3) make the change to reloc.c
|
|
4) rebuild the linker
|
|
5) repeat step 2
|
|
6) if the resulting object files are the same, you have at least
|
|
made it no worse
|
|
7) if they are different you have to figure out which version is
|
|
right. */

DESCRIPTION
|
|
The insides of a reloc code. The idea is that, eventually, there
|
|
will be one enumerator for every type of relocation we ever do.
|
|
Pass one of these values to <<bfd_reloc_type_lookup>>, and it'll
|
|
return a howto pointer.
|
|
|
|
This does mean that the application must determine the correct
|
|
enumerator value; you can't get a howto pointer from a random set
|
|
of attributes.

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

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).

ENUMDOC
|
|
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

BFD_RELOC_VTABLE_ENTRY

ENUMDOC
|
|
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 inheritance 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.
