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
3f9b03b5 30 en-masse and translated into an internal form. A common
252b5132
RH		 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.

119DESCRIPTION
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
6cee3f79
AC		 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.
252b5132
RH		 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
252b5132
RH		 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
252b5132
RH		 167 This could create a reloc pointing to <<foo>>, but leave the
168 offset in the data, something like:
169
252b5132
RH		 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
252b5132
RH		 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
252b5132
RH		 184| or.u r13,r0,hi16(_foo+0x12345678)
185| ld.b r2,r13,lo16(_foo+0x12345678)
186| jmp r1
187
252b5132
RH		 188 This should create two relocs, both pointing to <<_foo>>, and with
189 0x12340000 in their addend field. The data would consist of:
190
252b5132
RH		 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
252b5132
RH		 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
252b5132
RH		 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

230|0000000c 81c7e008 ; ret
231|00000010 81e80000 ; restore
232
252b5132
RH		 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.

RH		 557
558DESCRIPTION
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
572 this return @code{bfd_reloc_dangerous}.

662 the addend to be the negative of the position of the location

b34976b6 664 i386-aout, pcrel_offset is FALSE. Some other targets do not

717
718However, Ian wrote the following, regarding removing the line below,
719which explains why it is still enabled: --djm
720
721If you put a patch like that into BFD you need to check all the COFF
722linkers. I am fairly certain that patch will break coff-i386 (e.g.,
723SCO); see coff_i386_reloc in coff-i386.c where I worked around the
724problem in a different way. There may very well be a reason that the
725code works as it does.
726
727Hmmm. The first obvious point is that bfd_perform_relocation should
728not have any tests that depend upon the flavour. It's seem like
729entirely the wrong place for such a thing. The second obvious point
730is that the current code ignores the reloc addend when producing
1049f94e 731relocatable output for COFF. That's peculiar. In fact, I really
252b5132
RH		 732have no idea what the point of the line you want to remove is.
733
734A typical COFF reloc subtracts the old value of the symbol and adds in
735the new value to the location in the object file (if it's a pc
736relative reloc it adds the difference between the symbol value and the
737location). When relocating we need to preserve that property.
738
739BFD handles this by setting the addend to the negative of the old
740value of the symbol. Unfortunately it handles common symbols in a
741non-standard way (it doesn't subtract the old value) but that's a
742different story (we can't change it without losing backward
743compatibility with old object files) (coff-i386 does subtract the old
744value, to be compatible with existing coff-i386 targets, like SCO).
745
1049f94e
AM		 746So everything works fine when not producing relocatable output. When
747we are producing relocatable output, logically we should do exactly
748what we do when not producing relocatable output. Therefore, your
252b5132
RH		 749patch is correct. In fact, it should probably always just set
750reloc_entry->addend to 0 for all cases, since it is, in fact, going to
751add the value into the object file. This won't hurt the COFF code,
752which doesn't use the addend; I'm not sure what it will do to other
753formats (the thing to check for would be whether any formats both use
754the addend and set partial_inplace).
755
1049f94e 756When I wanted to make coff-i386 produce relocatable output, I ran
252b5132
RH		 757into the problem that you are running into: I wanted to remove that
758line. Rather than risk it, I made the coff-i386 relocs use a special
759function; it's coff_i386_reloc in coff-i386.c. The function
760specifically adds the addend field into the object file, knowing that
761bfd_perform_relocation is not going to. If you remove that line, then
762coff-i386.c will wind up adding the addend field in twice. It's
763trivial to fix; it just needs to be done.
764
765The problem with removing the line is just that it may break some
766working code. With BFD it's hard to be sure of anything. The right
767way to deal with this is simply to build and test at least all the
768supported COFF targets. It should be straightforward if time and disk
769space 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

1104
1105If you put a patch like that into BFD you need to check all the COFF
1106linkers. I am fairly certain that patch will break coff-i386 (e.g.,
1107SCO); see coff_i386_reloc in coff-i386.c where I worked around the
1108problem in a different way. There may very well be a reason that the
1109code works as it does.
1110
1111Hmmm. The first obvious point is that bfd_install_relocation should
1112not have any tests that depend upon the flavour. It's seem like
1113entirely the wrong place for such a thing. The second obvious point
1114is that the current code ignores the reloc addend when producing
1049f94e 1115relocatable output for COFF. That's peculiar. In fact, I really
252b5132
RH		 1116have no idea what the point of the line you want to remove is.
1117
1118A typical COFF reloc subtracts the old value of the symbol and adds in
1119the new value to the location in the object file (if it's a pc
1120relative reloc it adds the difference between the symbol value and the
1121location). When relocating we need to preserve that property.
1122
1123BFD handles this by setting the addend to the negative of the old
1124value of the symbol. Unfortunately it handles common symbols in a
1125non-standard way (it doesn't subtract the old value) but that's a
1126different story (we can't change it without losing backward
1127compatibility with old object files) (coff-i386 does subtract the old
1128value, to be compatible with existing coff-i386 targets, like SCO).
1129
1049f94e
AM		 1130So everything works fine when not producing relocatable output. When
1131we are producing relocatable output, logically we should do exactly
1132what we do when not producing relocatable output. Therefore, your
252b5132
RH		 1133patch is correct. In fact, it should probably always just set
1134reloc_entry->addend to 0 for all cases, since it is, in fact, going to
1135add the value into the object file. This won't hurt the COFF code,
1136which doesn't use the addend; I'm not sure what it will do to other
1137formats (the thing to check for would be whether any formats both use
1138the addend and set partial_inplace).
1139
1049f94e 1140When I wanted to make coff-i386 produce relocatable output, I ran
252b5132
RH		 1141into the problem that you are running into: I wanted to remove that
1142line. Rather than risk it, I made the coff-i386 relocs use a special
1143function; it's coff_i386_reloc in coff-i386.c. The function
1144specifically adds the addend field into the object file, knowing that
1145bfd_install_relocation is not going to. If you remove that line, then
1146coff-i386.c will wind up adding the addend field in twice. It's
1147trivial to fix; it just needs to be done.
1148
1149The problem with removing the line is just that it may break some
1150working code. With BFD it's hard to be sure of anything. The right
1151way to deal with this is simply to build and test at least all the
1152supported COFF targets. It should be straightforward if time and disk
1153space 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
b5f79c76 1165 right. */

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.
1637
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
2025ENUMDOC
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).
2032ENUM
2033 BFD_RELOC_ALPHA_GPDISP_LO16
2034ENUMDOC
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.

2052 BFD_RELOC_ALPHA_LITUSE
2053ENUMDOC
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.
2057
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.
2062
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.
2068
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)

88b6bae0 4297 These two relocations are used by the linker to determine which of
252b5132
RH		 4298 the entries in a C++ virtual function table are actually used. When
4299 the --gc-sections option is given, the linker will zero out the entries
4300 that are not used, so that the code for those functions need not be
4301 included in the output.
4302
4303 VTABLE_INHERIT is a zero-space relocation used to describe to the
7dee875e 4304 linker the inheritance tree of a C++ virtual function table. The
252b5132
RH		 4305 relocation's symbol should be the parent class' vtable, and the
4306 relocation should be located at the child vtable.
4307
4308 VTABLE_ENTRY is a zero-space relocation that describes the use of a
4309 virtual function table entry. The reloc's symbol should refer to the
4310 table of the class mentioned in the code. Off of that base, an offset
88b6bae0 4311 describes the entry that is being used. For Rela hosts, this offset
252b5132
RH		 4312 is stored in the reloc's addend. For Rel hosts, we are forced to put
4313 this offset in the reloc's section offset.
