25 SECTION
26 Relocations
27
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.
33
34 Relocations are maintained on a per section basis,
35 while symbols are maintained on a per BFD basis.
36
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
120
121 Here is a description of each of the fields within an <<arelent>>:
122
123 o <<sym_ptr_ptr>>
124
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.
136
137 o <<address>>
138
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.
146
147 o <<addend>>
148
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:
152
153 | char foo[];
154 | main()
155 | {
156 | return foo[0x12345678];
157 | }
158
159 Could be compiled into:
160
161 | linkw fp,#-4
162 | moveb @@#12345678,d0
163 | extbl d0
164 | unlk fp
165 | rts
166
167 This could create a reloc pointing to <<foo>>, but leave the
168 offset in the data, something like:
169
170 |RELOCATION RECORDS FOR [.text]:
171 |offset type value
172 |00000006 32 _foo
173 |
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
179
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:
183
184 | or.u r13,r0,hi16(_foo+0x12345678)
185 | ld.b r2,r13,lo16(_foo+0x12345678)
186 | jmp r1
187
188 This should create two relocs, both pointing to <<_foo>>, and with
189 0x12340000 in their addend field. The data would consist of:
190
191 |RELOCATION RECORDS FOR [.text]:
192 |offset type value
193 |00000002 HVRT16 _foo+0x12340000
194 |00000006 LVRT16 _foo+0x12340000
195 |
196 |00000000 5da05678 ; or.u r13,r0,0x5678
197 |00000004 1c4d5678 ; ld.b r2,r13,0x5678
198 |00000008 f400c001 ; jmp r1
199
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.
204
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.
212
213 | save %sp,-112,%sp
214 | sethi %hi(_foo+0x12345678),%g2
215 | ldsb [%g2+%lo(_foo+0x12345678)],%i0
216 | ret
217 | restore
218
219 Both relocs contain a pointer to <<foo>>, and the offsets
220 contain junk.
221
222 |RELOCATION RECORDS FOR [.text]:
223 |offset type value
224 |00000004 HI22 _foo+0x12345678
225 |00000008 LO10 _foo+0x12345678
226 |
227 |00000000 9de3bf90 ; save %sp,-112,%sp
228 |00000004 05000000 ; sethi %hi(_foo+0),%g2
229 |00000008 f048a000 ; ldsb [%g2+%lo(_foo+0)],%i0
230 |0000000c 81c7e008 ; ret
231 |00000010 81e80000 ; restore
232
233 o <<howto>>
234
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.

554
555 DESCRIPTION
556 If @var{output_bfd} is supplied to this function, the
557 generated image will be relocatable; the relocations are
558 copied to the output file after they have been changed to
559 reflect the new state of the world. There are two ways of
560 reflecting the results of partial linkage in an output file:
561 by modifying the output data in place, and by modifying the
562 relocation record. Some native formats (e.g., basic a.out and
563 basic coff) have no way of specifying an addend in the
564 relocation type, so the addend has to go in the output data.
565 This is no big deal since in these formats the output data

717
718 If you put a patch like that into BFD you need to check all the COFF
719 linkers. I am fairly certain that patch will break coff-i386 (e.g.,
720 SCO); see coff_i386_reloc in coff-i386.c where I worked around the
721 problem in a different way. There may very well be a reason that the
722 code works as it does.
723
724 Hmmm. The first obvious point is that bfd_perform_relocation should
725 not have any tests that depend upon the flavour. It's seem like
726 entirely the wrong place for such a thing. The second obvious point
727 is that the current code ignores the reloc addend when producing
728 relocatable output for COFF. That's peculiar. In fact, I really
729 have no idea what the point of the line you want to remove is.
730
731 A typical COFF reloc subtracts the old value of the symbol and adds in
732 the new value to the location in the object file (if it's a pc
733 relative reloc it adds the difference between the symbol value and the
734 location). When relocating we need to preserve that property.
735
736 BFD handles this by setting the addend to the negative of the old
737 value of the symbol. Unfortunately it handles common symbols in a
738 non-standard way (it doesn't subtract the old value) but that's a
739 different story (we can't change it without losing backward
740 compatibility with old object files) (coff-i386 does subtract the old
741 value, to be compatible with existing coff-i386 targets, like SCO).
742
743 So everything works fine when not producing relocatable output. When
744 we are producing relocatable output, logically we should do exactly
745 what we do when not producing relocatable output. Therefore, your
746 patch is correct. In fact, it should probably always just set
747 reloc_entry->addend to 0 for all cases, since it is, in fact, going to
748 add the value into the object file. This won't hurt the COFF code,
749 which doesn't use the addend; I'm not sure what it will do to other
750 formats (the thing to check for would be whether any formats both use
751 the addend and set partial_inplace).
752
753 When I wanted to make coff-i386 produce relocatable output, I ran
754 into the problem that you are running into: I wanted to remove that
755 line. Rather than risk it, I made the coff-i386 relocs use a special
756 function; it's coff_i386_reloc in coff-i386.c. The function
757 specifically adds the addend field into the object file, knowing that
758 bfd_perform_relocation is not going to. If you remove that line, then
759 coff-i386.c will wind up adding the addend field in twice. It's
760 trivial to fix; it just needs to be done.
761
762 The problem with removing the line is just that it may break some
763 working code. With BFD it's hard to be sure of anything. The right
764 way to deal with this is simply to build and test at least all the
765 supported COFF targets. It should be straightforward if time and disk
766 space consuming. For each target:
767 1) build the linker
768 2) generate some executable, and link it using -r (I would
769 probably use paranoia.o and link against newlib/libc.a, which
770 for all the supported targets would be available in
771 /usr/cygnus/progressive/H-host/target/lib/libc.a).
772 3) make the change to reloc.c
773 4) rebuild the linker
774 5) repeat step 2
775 6) if the resulting object files are the same, you have at least
776 made it no worse
777 7) if they are different you have to figure out which version is
778 right

1115 A typical COFF reloc subtracts the old value of the symbol and adds in
1116 the new value to the location in the object file (if it's a pc
1117 relative reloc it adds the difference between the symbol value and the
1118 location). When relocating we need to preserve that property.
1119
1120 BFD handles this by setting the addend to the negative of the old
1121 value of the symbol. Unfortunately it handles common symbols in a
1122 non-standard way (it doesn't subtract the old value) but that's a
1123 different story (we can't change it without losing backward
1124 compatibility with old object files) (coff-i386 does subtract the old
1125 value, to be compatible with existing coff-i386 targets, like SCO).
1126
1127 So everything works fine when not producing relocatable output. When
1128 we are producing relocatable output, logically we should do exactly
1129 what we do when not producing relocatable output. Therefore, your
1130 patch is correct. In fact, it should probably always just set
1131 reloc_entry->addend to 0 for all cases, since it is, in fact, going to
1132 add the value into the object file. This won't hurt the COFF code,
1133 which doesn't use the addend; I'm not sure what it will do to other
1134 formats (the thing to check for would be whether any formats both use
1135 the addend and set partial_inplace).
1136
1137 When I wanted to make coff-i386 produce relocatable output, I ran
1138 into the problem that you are running into: I wanted to remove that
1139 line. Rather than risk it, I made the coff-i386 relocs use a special
1140 function; it's coff_i386_reloc in coff-i386.c. The function
1141 specifically adds the addend field into the object file, knowing that
1142 bfd_install_relocation is not going to. If you remove that line, then
1143 coff-i386.c will wind up adding the addend field in twice. It's
1144 trivial to fix; it just needs to be done.
1145
1146 The problem with removing the line is just that it may break some
1147 working code. With BFD it's hard to be sure of anything. The right
1148 way to deal with this is simply to build and test at least all the
1149 supported COFF targets. It should be straightforward if time and disk
1150 space consuming. For each target:
1151 1) build the linker
1152 2) generate some executable, and link it using -r (I would
1153 probably use paranoia.o and link against newlib/libc.a, which
1154 for all the supported targets would be available in
1155 /usr/cygnus/progressive/H-host/target/lib/libc.a).
1156 3) make the change to reloc.c
1157 4) rebuild the linker
1158 5) repeat step 2
1159 6) if the resulting object files are the same, you have at least
1160 made it no worse
1161 7) if they are different you have to figure out which version is
1162 right. */

1640 The insides of a reloc code. The idea is that, eventually, there
1641 will be one enumerator for every type of relocation we ever do.
1642 Pass one of these values to <<bfd_reloc_type_lookup>>, and it'll
1643 return a howto pointer.
1644
1645 This does mean that the application must determine the correct
1646 enumerator value; you can't get a howto pointer from a random set
1647 of attributes.

2040 "addend" in some special way.
2041 For GPDISP_HI16 ("gpdisp") relocations, the symbol is ignored when
2042 writing; when reading, it will be the absolute section symbol. The
2043 addend is the displacement in bytes of the "lda" instruction from
2044 the "ldah" instruction (which is at the address of this reloc).

2066 ENUMDOC
2067 The Alpha LITERAL/LITUSE relocs are produced by a symbol reference;
2068 the assembler turns it into a LDQ instruction to load the address of
2069 the symbol, and then fills in a register in the real instruction.
2070
2071 The LITERAL reloc, at the LDQ instruction, refers to the .lita
2072 section symbol. The addend is ignored when writing, but is filled
2073 in with the file's GP value on reading, for convenience, as with the
2074 GPDISP_LO16 reloc.
2075
2076 The ELF_LITERAL reloc is somewhere between 16_GOTOFF and GPDISP_LO16.
2077 It should refer to the symbol to be referenced, as with 16_GOTOFF,
2078 but it generates output not based on the position within the .got
2079 section, but relative to the GP value chosen for the file during the
2080 final link stage.
2081
2082 The LITUSE reloc, on the instruction using the loaded address, gives
2083 information to the linker that it might be able to use to optimize
2084 away some literal section references. The symbol is ignored (read
2085 as the absolute section symbol), and the "addend" indicates the type
2086 of instruction using the register:
2087 1 - "memory" fmt insn
2088 2 - byte-manipulation (byte offset reg)
2089 3 - jsr (target of branch)

4535 ENUMDOC
4536 These two relocations are used by the linker to determine which of
4537 the entries in a C++ virtual function table are actually used. When
4538 the --gc-sections option is given, the linker will zero out the entries
4539 that are not used, so that the code for those functions need not be
4540 included in the output.
4541
4542 VTABLE_INHERIT is a zero-space relocation used to describe to the
4543 linker the inheritance tree of a C++ virtual function table. The
4544 relocation's symbol should be the parent class' vtable, and the
4545 relocation should be located at the child vtable.
4546
4547 VTABLE_ENTRY is a zero-space relocation that describes the use of a
4548 virtual function table entry. The reloc's symbol should refer to the
4549 table of the class mentioned in the code. Off of that base, an offset
4550 describes the entry that is being used. For Rela hosts, this offset
4551 is stored in the reloc's addend. For Rel hosts, we are forced to put
4552 this offset in the reloc's section offset.
