25 SECTION
26 Relocations
28 BFD maintains relocations in much the same way it maintains
29 symbols: they are left alone until required, then read in
30 en-masse and translated into an internal form. A common
31 routine <<bfd_perform_relocation>> acts upon the
32 canonical form to do the fixup.
34 Relocations are maintained on a per section basis,
35 while symbols are maintained on a per BFD basis.
37 All that a back end has to do to fit the BFD interface is to create
38 a <<struct reloc_cache_entry>> for each relocation
39 in a particular section, and fill in the right bits of the structures.

119 DESCRIPTION
121 Here is a description of each of the fields within an <<arelent>>:
123 o <<sym_ptr_ptr>>
125 The symbol table pointer points to a pointer to the symbol
126 associated with the relocation request. It is the pointer
127 into the table returned by the back end's
128 <<canonicalize_symtab>> action. @xref{Symbols}. The symbol is
129 referenced through a pointer to a pointer so that tools like
130 the linker can fix up all the symbols of the same name by
131 modifying only one pointer. The relocation routine looks in
132 the symbol and uses the base of the section the symbol is
133 attached to and the value of the symbol as the initial
134 relocation offset. If the symbol pointer is zero, then the
135 section provided is looked up.
137 o <<address>>
139 The <<address>> field gives the offset in bytes from the base of
140 the section data which owns the relocation record to the first
141 byte of relocatable information. The actual data relocated
142 will be relative to this point; for example, a relocation
143 type which modifies the bottom two bytes of a four byte word
144 would not touch the first byte pointed to in a big endian
145 world.
147 o <<addend>>
149 The <<addend>> is a value provided by the back end to be added (!)
150 to the relocation offset. Its interpretation is dependent upon
151 the howto. For example, on the 68k the code:
153 | char foo[];
154 | main()
156 | return foo[0x12345678];
159 Could be compiled into:
161 | linkw fp,#-4
162 | moveb @@#12345678,d0
163 | extbl d0
164 | unlk fp
165 | rts
167 This could create a reloc pointing to <<foo>>, but leave the
168 offset in the data, something like:
170 |RELOCATION RECORDS FOR [.text]:
171 |offset type value
172 |00000006 32 _foo
174 |00000000 4e56 fffc ; linkw fp,#-4
175 |00000004 1039 1234 5678 ; moveb @@#12345678,d0
176 |0000000a 49c0 ; extbl d0
177 |0000000c 4e5e ; unlk fp
178 |0000000e 4e75 ; rts
180 Using coff and an 88k, some instructions don't have enough
181 space in them to represent the full address range, and
182 pointers have to be loaded in two parts. So you'd get something like:
184 | or.u r13,r0,hi16(_foo+0x12345678)
185 | ld.b r2,r13,lo16(_foo+0x12345678)
186 | jmp r1
188 This should create two relocs, both pointing to <<_foo>>, and with
189 0x12340000 in their addend field. The data would consist of:
191 |RELOCATION RECORDS FOR [.text]:
192 |offset type value
193 |00000002 HVRT16 _foo+0x12340000
194 |00000006 LVRT16 _foo+0x12340000
196 |00000000 5da05678 ; or.u r13,r0,0x5678
197 |00000004 1c4d5678 ; ld.b r2,r13,0x5678
198 |00000008 f400c001 ; jmp r1
200 The relocation routine digs out the value from the data, adds
201 it to the addend to get the original offset, and then adds the
202 value of <<_foo>>. Note that all 32 bits have to be kept around
203 somewhere, to cope with carry from bit 15 to bit 16.
205 One further example is the sparc and the a.out format. The
206 sparc has a similar problem to the 88k, in that some
207 instructions don't have room for an entire offset, but on the
208 sparc the parts are created in odd sized lumps. The designers of
209 the a.out format chose to not use the data within the section
210 for storing part of the offset; all the offset is kept within
211 the reloc. Anything in the data should be ignored.
213 | save %sp,-112,%sp
214 | sethi %hi(_foo+0x12345678),%g2
215 | ldsb [%g2+%lo(_foo+0x12345678)],%i0
216 | ret
217 | restore
219 Both relocs contain a pointer to <<foo>>, and the offsets
220 contain junk.
222 |RELOCATION RECORDS FOR [.text]:
223 |offset type value
224 |00000004 HI22 _foo+0x12345678
225 |00000008 LO10 _foo+0x12345678
227 |00000000 9de3bf90 ; save %sp,-112,%sp

230 |0000000c 81c7e008 ; ret
231 |00000010 81e80000 ; restore
233 o <<howto>>
235 The <<howto>> field can be imagined as a
236 relocation instruction. It is a pointer to a structure which
237 contains information on what to do with all of the other
238 information in the reloc record and data section. A back end
239 would normally have a relocation instruction set and turn
240 relocations into pointers to the correct structure on input -
241 but it would be possible to create each howto field on demand.

558 DESCRIPTION
559 If @var{output_bfd} is supplied to this function, the
560 generated image will be relocatable; the relocations are
561 copied to the output file after they have been changed to
562 reflect the new state of the world. There are two ways of
563 reflecting the results of partial linkage in an output file:
564 by modifying the output data in place, and by modifying the
565 relocation record. Some native formats (e.g., basic a.out and
566 basic coff) have no way of specifying an addend in the
567 relocation type, so the addend has to go in the output data.
568 This is no big deal since in these formats the output data
569 slot will always be big enough for the addend. Complex reloc
570 types with addends were invented to solve just this problem.
571 The @var{error_message} argument is set to an error message if

660 If pcrel_offset is set, we must further subtract the position

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

1105 If you put a patch like that into BFD you need to check all the COFF
1106 linkers. I am fairly certain that patch will break coff-i386 (e.g.,
1107 SCO); see coff_i386_reloc in coff-i386.c where I worked around the
1108 problem in a different way. There may very well be a reason that the
1109 code works as it does.
1111 Hmmm. The first obvious point is that bfd_install_relocation should
1112 not have any tests that depend upon the flavour. It's seem like
1113 entirely the wrong place for such a thing. The second obvious point
1114 is that the current code ignores the reloc addend when producing
1115 relocatable output for COFF. That's peculiar. In fact, I really
1116 have no idea what the point of the line you want to remove is.
1118 A typical COFF reloc subtracts the old value of the symbol and adds in
1119 the new value to the location in the object file (if it's a pc
1120 relative reloc it adds the difference between the symbol value and the
1121 location). When relocating we need to preserve that property.
1123 BFD handles this by setting the addend to the negative of the old
1124 value of the symbol. Unfortunately it handles common symbols in a
1125 non-standard way (it doesn't subtract the old value) but that's a
1126 different story (we can't change it without losing backward
1127 compatibility with old object files) (coff-i386 does subtract the old
1128 value, to be compatible with existing coff-i386 targets, like SCO).
1130 So everything works fine when not producing relocatable output. When
1131 we are producing relocatable output, logically we should do exactly
1132 what we do when not producing relocatable output. Therefore, your
1133 patch is correct. In fact, it should probably always just set
1134 reloc_entry->addend to 0 for all cases, since it is, in fact, going to
1135 add the value into the object file. This won't hurt the COFF code,
1136 which doesn't use the addend; I'm not sure what it will do to other
1137 formats (the thing to check for would be whether any formats both use
1138 the addend and set partial_inplace).
1140 When I wanted to make coff-i386 produce relocatable output, I ran
1141 into the problem that you are running into: I wanted to remove that
1142 line. Rather than risk it, I made the coff-i386 relocs use a special
1143 function; it's coff_i386_reloc in coff-i386.c. The function
1144 specifically adds the addend field into the object file, knowing that
1145 bfd_install_relocation is not going to. If you remove that line, then
1146 coff-i386.c will wind up adding the addend field in twice. It's
1147 trivial to fix; it just needs to be done.
1149 The problem with removing the line is just that it may break some
1150 working code. With BFD it's hard to be sure of anything. The right
1151 way to deal with this is simply to build and test at least all the
1152 supported COFF targets. It should be straightforward if time and disk
1153 space consuming. For each target:
1154 1) build the linker
1155 2) generate some executable, and link it using -r (I would
1156 probably use paranoia.o and link against newlib/libc.a, which
1157 for all the supported targets would be available in
1158 /usr/cygnus/progressive/H-host/target/lib/libc.a).
1159 3) make the change to reloc.c
1160 4) rebuild the linker
1161 5) repeat step 2
1162 6) if the resulting object files are the same, you have at least
1163 made it no worse
1164 7) if they are different you have to figure out which version is

1624 using this bit of code.

1630 bfd_reloc_code_type
1632 DESCRIPTION
1633 The insides of a reloc code. The idea is that, eventually, there
1634 will be one enumerator for every type of relocation we ever do.
1635 Pass one of these values to <<bfd_reloc_type_lookup>>, and it'll
1636 return a howto pointer.
1638 This does mean that the application must determine the correct
1639 enumerator value; you can't get a howto pointer from a random set
1640 of attributes.

2024 BFD_RELOC_ALPHA_GPDISP_HI16
2025 ENUMDOC
2026 Alpha ECOFF and ELF relocations. Some of these treat the symbol or
2027 "addend" in some special way.
2028 For GPDISP_HI16 ("gpdisp") relocations, the symbol is ignored when
2029 writing; when reading, it will be the absolute section symbol. The
2030 addend is the displacement in bytes of the "lda" instruction from
2031 the "ldah" instruction (which is at the address of this reloc).
2032 ENUM
2033 BFD_RELOC_ALPHA_GPDISP_LO16
2034 ENUMDOC
2035 For GPDISP_LO16 ("ignore") relocations, the symbol is handled as
2036 with GPDISP_HI16 relocs. The addend is ignored when writing the
2037 relocations out, and is filled in with the file's GP value on
2038 reading, for convenience.
2040 ENUM
2041 BFD_RELOC_ALPHA_GPDISP
2042 ENUMDOC
2043 The ELF GPDISP relocation is exactly the same as the GPDISP_HI16
2044 relocation except that there is no accompanying GPDISP_LO16
2045 relocation.

2049 ENUMX
2050 BFD_RELOC_ALPHA_ELF_LITERAL
2051 ENUMX
2052 BFD_RELOC_ALPHA_LITUSE
2053 ENUMDOC
2054 The Alpha LITERAL/LITUSE relocs are produced by a symbol reference;
2055 the assembler turns it into a LDQ instruction to load the address of
2056 the symbol, and then fills in a register in the real instruction.
2058 The LITERAL reloc, at the LDQ instruction, refers to the .lita
2059 section symbol. The addend is ignored when writing, but is filled
2060 in with the file's GP value on reading, for convenience, as with the
2061 GPDISP_LO16 reloc.
2063 The ELF_LITERAL reloc is somewhere between 16_GOTOFF and GPDISP_LO16.
2064 It should refer to the symbol to be referenced, as with 16_GOTOFF,
2065 but it generates output not based on the position within the .got
2066 section, but relative to the GP value chosen for the file during the
2067 final link stage.
2069 The LITUSE reloc, on the instruction using the loaded address, gives
2070 information to the linker that it might be able to use to optimize
2071 away some literal section references. The symbol is ignored (read
2072 as the absolute section symbol), and the "addend" indicates the type
2073 of instruction using the register:
2074 1 - "memory" fmt insn
2075 2 - byte-manipulation (byte offset reg)
2076 3 - jsr (target of branch)
2078 ENUM
2079 BFD_RELOC_ALPHA_HINT
2080 ENUMDOC
2081 The HINT relocation indicates a value that should be filled into the

4305 These two relocations are used by the linker to determine which of
4306 the entries in a C++ virtual function table are actually used. When
4307 the --gc-sections option is given, the linker will zero out the entries
4308 that are not used, so that the code for those functions need not be
4309 included in the output.
4311 VTABLE_INHERIT is a zero-space relocation used to describe to the
4312 linker the inheritance tree of a C++ virtual function table. The
4313 relocation's symbol should be the parent class' vtable, and the
4314 relocation should be located at the child vtable.
4316 VTABLE_ENTRY is a zero-space relocation that describes the use of a
4317 virtual function table entry. The reloc's symbol should refer to the
4318 table of the class mentioned in the code. Off of that base, an offset
4319 describes the entry that is being used. For Rela hosts, this offset
4320 is stored in the reloc's addend. For Rel hosts, we are forced to put
4321 this offset in the reloc's section offset.
