- Relocations are maintained on a per section 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
- <<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.
-
- 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

-|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.

- This is no big deal since in these formats the output data

-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
-relocateable 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 relocateable output. When
-we are producing relocateable output, logically we should do exactly
-what we do when not producing relocateable 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 relocateable 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

-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
-relocateable 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 relocateable output. When
-we are producing relocateable output, logically we should do exactly
-what we do when not producing relocateable 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 relocateable 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

-displacement (<<32_PCREL_S2>> -- 32 bits, shifted 2) is used on the

- For GPDISP_HI16 ("gpdisp") relocations, the symbol is ignored when

- 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
- 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)
-
- The GNU linker currently doesn't do any of this optimizing.

- 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 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.
