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

118DESCRIPTION
119
120 Here is a description of each of the fields within an <<arelent>>:
121
122 o <<sym_ptr_ptr>>
123
124 The symbol table pointer points to a pointer to the symbol
125 associated with the relocation request. It is the pointer
126 into the table returned by the back end's
127 <<canonicalize_symtab>> action. @xref{Symbols}. The symbol is
128 referenced through a pointer to a pointer so that tools like
129 the linker can fix up all the symbols of the same name by
130 modifying only one pointer. The relocation routine looks in
131 the symbol and uses the base of the section the symbol is
132 attached to and the value of the symbol as the initial
133 relocation offset. If the symbol pointer is zero, then the
134 section provided is looked up.
135
136 o <<address>>
137
138 The <<address>> field gives the offset in bytes from the base of
139 the section data which owns the relocation record to the first
140 byte of relocatable information. The actual data relocated
141 will be relative to this point; for example, a relocation
142 type which modifies the bottom two bytes of a four byte word
143 would not touch the first byte pointed to in a big endian
144 world.
145
146 o <<addend>>
147
148 The <<addend>> is a value provided by the back end to be added (!)
149 to the relocation offset. Its interpretation is dependent upon
150 the howto. For example, on the 68k the code:
151
152| char foo[];
153| main()
154| {
155| return foo[0x12345678];
156| }
157
158 Could be compiled into:
159
160| linkw fp,#-4
161| moveb @@#12345678,d0
162| extbl d0
163| unlk fp
164| rts
165
166 This could create a reloc pointing to <<foo>>, but leave the
167 offset in the data, something like:
168
169|RELOCATION RECORDS FOR [.text]:
170|offset type value
171|00000006 32 _foo
172|
173|00000000 4e56 fffc ; linkw fp,#-4
174|00000004 1039 1234 5678 ; moveb @@#12345678,d0
175|0000000a 49c0 ; extbl d0
176|0000000c 4e5e ; unlk fp
177|0000000e 4e75 ; rts
178
179 Using coff and an 88k, some instructions don't have enough
180 space in them to represent the full address range, and
181 pointers have to be loaded in two parts. So you'd get something like:
182
183| or.u r13,r0,hi16(_foo+0x12345678)
184| ld.b r2,r13,lo16(_foo+0x12345678)
185| jmp r1
186
187 This should create two relocs, both pointing to <<_foo>>, and with
188 0x12340000 in their addend field. The data would consist of:
189
190|RELOCATION RECORDS FOR [.text]:
191|offset type value
192|00000002 HVRT16 _foo+0x12340000
193|00000006 LVRT16 _foo+0x12340000
194|
195|00000000 5da05678 ; or.u r13,r0,0x5678
196|00000004 1c4d5678 ; ld.b r2,r13,0x5678
197|00000008 f400c001 ; jmp r1
198
199 The relocation routine digs out the value from the data, adds
200 it to the addend to get the original offset, and then adds the
201 value of <<_foo>>. Note that all 32 bits have to be kept around
202 somewhere, to cope with carry from bit 15 to bit 16.
203
204 One further example is the sparc and the a.out format. The
205 sparc has a similar problem to the 88k, in that some
206 instructions don't have room for an entire offset, but on the
207 sparc the parts are created in odd sized lumps. The designers of
208 the a.out format chose to not use the data within the section
209 for storing part of the offset; all the offset is kept within
210 the reloc. Anything in the data should be ignored.
211
212| save %sp,-112,%sp
213| sethi %hi(_foo+0x12345678),%g2
214| ldsb [%g2+%lo(_foo+0x12345678)],%i0
215| ret
216| restore
217
218 Both relocs contain a pointer to <<foo>>, and the offsets
219 contain junk.
220
221|RELOCATION RECORDS FOR [.text]:
222|offset type value
223|00000004 HI22 _foo+0x12345678
224|00000008 LO10 _foo+0x12345678
225|
226|00000000 9de3bf90 ; save %sp,-112,%sp
227|00000004 05000000 ; sethi %hi(_foo+0),%g2
228|00000008 f048a000 ; ldsb [%g2+%lo(_foo+0)],%i0
229|0000000c 81c7e008 ; ret
230|00000010 81e80000 ; restore
231
232 o <<howto>>
233
234 The <<howto>> field can be imagined as a
235 relocation instruction. It is a pointer to a structure which
236 contains information on what to do with all of the other
237 information in the reloc record and data section. A back end
238 would normally have a relocation instruction set and turn
239 relocations into pointers to the correct structure on input -
240 but it would be possible to create each howto field on demand.

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

662 We start by subtracting the address of the section containing
663 the location.
664
665 If pcrel_offset is set, we must further subtract the position
666 of the location within the section. Some targets arrange for
667 the addend to be the negative of the position of the location
668 within the section; for example, i386-aout does this. For
669 i386-aout, pcrel_offset is FALSE. Some other targets do not
670 include the position of the location; for example, m88kbcs,
671 or ELF. For those targets, pcrel_offset is TRUE.

676 up with the negative of the location within the section,

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

1111which explains why it is still enabled: --djm
1112
1113If you put a patch like that into BFD you need to check all the COFF
1114linkers. I am fairly certain that patch will break coff-i386 (e.g.,
1115SCO); see coff_i386_reloc in coff-i386.c where I worked around the
1116problem in a different way. There may very well be a reason that the
1117code works as it does.
1118
1119Hmmm. The first obvious point is that bfd_install_relocation should
1120not have any tests that depend upon the flavour. It's seem like
1121entirely the wrong place for such a thing. The second obvious point
1122is that the current code ignores the reloc addend when producing
1123relocatable output for COFF. That's peculiar. In fact, I really
1124have no idea what the point of the line you want to remove is.
1125
1126A typical COFF reloc subtracts the old value of the symbol and adds in
1127the new value to the location in the object file (if it's a pc
1128relative reloc it adds the difference between the symbol value and the
1129location). When relocating we need to preserve that property.
1130
1131BFD handles this by setting the addend to the negative of the old
1132value of the symbol. Unfortunately it handles common symbols in a
1133non-standard way (it doesn't subtract the old value) but that's a
1134different story (we can't change it without losing backward
1135compatibility with old object files) (coff-i386 does subtract the old
1136value, to be compatible with existing coff-i386 targets, like SCO).
1137
1138So everything works fine when not producing relocatable output. When
1139we are producing relocatable output, logically we should do exactly
1140what we do when not producing relocatable output. Therefore, your
1141patch is correct. In fact, it should probably always just set
1142reloc_entry->addend to 0 for all cases, since it is, in fact, going to
1143add the value into the object file. This won't hurt the COFF code,
1144which doesn't use the addend; I'm not sure what it will do to other
1145formats (the thing to check for would be whether any formats both use
1146the addend and set partial_inplace).
1147
1148When I wanted to make coff-i386 produce relocatable output, I ran
1149into the problem that you are running into: I wanted to remove that
1150line. Rather than risk it, I made the coff-i386 relocs use a special
1151function; it's coff_i386_reloc in coff-i386.c. The function
1152specifically adds the addend field into the object file, knowing that
1153bfd_install_relocation is not going to. If you remove that line, then
1154coff-i386.c will wind up adding the addend field in twice. It's
1155trivial to fix; it just needs to be done.
1156
1157The problem with removing the line is just that it may break some
1158working code. With BFD it's hard to be sure of anything. The right
1159way to deal with this is simply to build and test at least all the
1160supported COFF targets. It should be straightforward if time and disk
1161space consuming. For each target:
1162 1) build the linker
1163 2) generate some executable, and link it using -r (I would
1164 probably use paranoia.o and link against newlib/libc.a, which
1165 for all the supported targets would be available in
1166 /usr/cygnus/progressive/H-host/target/lib/libc.a).
1167 3) make the change to reloc.c
1168 4) rebuild the linker
1169 5) repeat step 2
1170 6) if the resulting object files are the same, you have at least
1171 made it no worse
1172 7) if they are different you have to figure out which version is
1173 right. */

1600DESCRIPTION
1601 The insides of a reloc code. The idea is that, eventually, there
1602 will be one enumerator for every type of relocation we ever do.
1603 Pass one of these values to <<bfd_reloc_type_lookup>>, and it'll
1604 return a howto pointer.
1605
1606 This does mean that the application must determine the correct
1607 enumerator value; you can't get a howto pointer from a random set
1608 of attributes.

1924 For GPDISP_HI16 ("gpdisp") relocations, the symbol is ignored when
1925 writing; when reading, it will be the absolute section symbol. The

1950 The Alpha LITERAL/LITUSE relocs are produced by a symbol reference;
1951 the assembler turns it into a LDQ instruction to load the address of
1952 the symbol, and then fills in a register in the real instruction.
1953
1954 The LITERAL reloc, at the LDQ instruction, refers to the .lita
1955 section symbol. The addend is ignored when writing, but is filled
1956 in with the file's GP value on reading, for convenience, as with the
1957 GPDISP_LO16 reloc.
1958
1959 The ELF_LITERAL reloc is somewhere between 16_GOTOFF and GPDISP_LO16.
1960 It should refer to the symbol to be referenced, as with 16_GOTOFF,
1961 but it generates output not based on the position within the .got
1962 section, but relative to the GP value chosen for the file during the
1963 final link stage.
1964
1965 The LITUSE reloc, on the instruction using the loaded address, gives
1966 information to the linker that it might be able to use to optimize
1967 away some literal section references. The symbol is ignored (read
1968 as the absolute section symbol), and the "addend" indicates the type
1969 of instruction using the register:
1970 1 - "memory" fmt insn

2060 High 16 bits of 32-bit value but the low 16 bits will be sign
2061 extended and added to form the final result. If the low 16
2062 bits form a negative number, we need to add one to the high value
2063 to compensate for the borrow when the low bits are added.

3540ENUMDOC
3541 These two relocations are used by the linker to determine which of
3542 the entries in a C++ virtual function table are actually used. When
3543 the --gc-sections option is given, the linker will zero out the entries
3544 that are not used, so that the code for those functions need not be
3545 included in the output.
3546
3547 VTABLE_INHERIT is a zero-space relocation used to describe to the
3548 linker the inheritance tree of a C++ virtual function table. The
3549 relocation's symbol should be the parent class' vtable, and the
3550 relocation should be located at the child vtable.
3551
3552 VTABLE_ENTRY is a zero-space relocation that describes the use of a
3553 virtual function table entry. The reloc's symbol should refer to the
3554 table of the class mentioned in the code. Off of that base, an offset
3555 describes the entry that is being used. For Rela hosts, this offset
3556 is stored in the reloc's addend. For Rel hosts, we are forced to put
3557 this offset in the reloc's section offset.
