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
3f9b03b5 29 en-masse and translated into an internal form. A common
252b5132
RH
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
6cee3f79
AC
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.
252b5132
RH
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
252b5132
RH
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
252b5132
RH
166 This could create a reloc pointing to <<foo>>, but leave the
167 offset in the data, something like:
168
252b5132
RH
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
252b5132
RH
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
252b5132
RH
183| or.u r13,r0,hi16(_foo+0x12345678)
184| ld.b r2,r13,lo16(_foo+0x12345678)
185| jmp r1
186
252b5132
RH
187 This should create two relocs, both pointing to <<_foo>>, and with
188 0x12340000 in their addend field. The data would consist of:
189
252b5132
RH
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
252b5132
RH
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
252b5132
RH
221|RELOCATION RECORDS FOR [.text]:
222|offset type value
223|00000004 HI22 _foo+0x12345678

230|00000010 81e80000 ; restore
231
252b5132
RH
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.

556
557DESCRIPTION
558 If @var{output_bfd} is supplied to this function, the
559 generated image will be relocatable; the relocations are
560 copied to the output file after they have been changed to
561 reflect the new state of the world. There are two ways of
562 reflecting the results of partial linkage in an output file:
563 by modifying the output data in place, and by modifying the
564 relocation record. Some native formats (e.g., basic a.out and
565 basic coff) have no way of specifying an addend in the
566 relocation type, so the addend has to go in the output data.
567 This is no big deal since in these formats the output data
568 slot will always be big enough for the addend. Complex reloc
569 types with addends were invented to solve just this problem.
570 The @var{error_message} argument is set to an error message if
571 this return @code{bfd_reloc_dangerous}.

717However, Ian wrote the following, regarding removing the line below,
718which explains why it is still enabled: --djm
719
720If you put a patch like that into BFD you need to check all the COFF
721linkers. I am fairly certain that patch will break coff-i386 (e.g.,
722SCO); see coff_i386_reloc in coff-i386.c where I worked around the
723problem in a different way. There may very well be a reason that the
724code works as it does.
725
726Hmmm. The first obvious point is that bfd_perform_relocation should
727not have any tests that depend upon the flavour. It's seem like
728entirely the wrong place for such a thing. The second obvious point
729is that the current code ignores the reloc addend when producing
1049f94e 730relocatable output for COFF. That's peculiar. In fact, I really
252b5132
RH
731have no idea what the point of the line you want to remove is.
732
733A typical COFF reloc subtracts the old value of the symbol and adds in
734the new value to the location in the object file (if it's a pc
735relative reloc it adds the difference between the symbol value and the
736location). When relocating we need to preserve that property.
737
738BFD handles this by setting the addend to the negative of the old
739value of the symbol. Unfortunately it handles common symbols in a
740non-standard way (it doesn't subtract the old value) but that's a
741different story (we can't change it without losing backward
742compatibility with old object files) (coff-i386 does subtract the old
743value, to be compatible with existing coff-i386 targets, like SCO).
744
1049f94e
AM
745So everything works fine when not producing relocatable output. When
746we are producing relocatable output, logically we should do exactly
747what we do when not producing relocatable output. Therefore, your
252b5132
RH
748patch is correct. In fact, it should probably always just set
749reloc_entry->addend to 0 for all cases, since it is, in fact, going to
750add the value into the object file. This won't hurt the COFF code,
751which doesn't use the addend; I'm not sure what it will do to other
752formats (the thing to check for would be whether any formats both use
753the addend and set partial_inplace).
754
1049f94e 755When I wanted to make coff-i386 produce relocatable output, I ran
252b5132
RH
756into the problem that you are running into: I wanted to remove that
757line. Rather than risk it, I made the coff-i386 relocs use a special
758function; it's coff_i386_reloc in coff-i386.c. The function
759specifically adds the addend field into the object file, knowing that
760bfd_perform_relocation is not going to. If you remove that line, then
761coff-i386.c will wind up adding the addend field in twice. It's
762trivial to fix; it just needs to be done.
763
764The problem with removing the line is just that it may break some
765working code. With BFD it's hard to be sure of anything. The right
766way to deal with this is simply to build and test at least all the
767supported COFF targets. It should be straightforward if time and disk
768space consuming. For each target:
769 1) build the linker
770 2) generate some executable, and link it using -r (I would
771 probably use paranoia.o and link against newlib/libc.a, which
772 for all the supported targets would be available in
773 /usr/cygnus/progressive/H-host/target/lib/libc.a).
774 3) make the change to reloc.c
775 4) rebuild the linker
776 5) repeat step 2
777 6) if the resulting object files are the same, you have at least
778 made it no worse
779 7) if they are different you have to figure out which version is
780 right

1103
1104If you put a patch like that into BFD you need to check all the COFF
1105linkers. I am fairly certain that patch will break coff-i386 (e.g.,
1106SCO); see coff_i386_reloc in coff-i386.c where I worked around the
1107problem in a different way. There may very well be a reason that the
1108code works as it does.
1109
1110Hmmm. The first obvious point is that bfd_install_relocation should
1111not have any tests that depend upon the flavour. It's seem like
1112entirely the wrong place for such a thing. The second obvious point
1113is that the current code ignores the reloc addend when producing
1049f94e 1114relocatable output for COFF. That's peculiar. In fact, I really
252b5132
RH
1115have no idea what the point of the line you want to remove is.
1116
1117A typical COFF reloc subtracts the old value of the symbol and adds in
1118the new value to the location in the object file (if it's a pc
1119relative reloc it adds the difference between the symbol value and the
1120location). When relocating we need to preserve that property.
1121
1122BFD handles this by setting the addend to the negative of the old
1123value of the symbol. Unfortunately it handles common symbols in a
1124non-standard way (it doesn't subtract the old value) but that's a
1125different story (we can't change it without losing backward
1126compatibility with old object files) (coff-i386 does subtract the old
1127value, to be compatible with existing coff-i386 targets, like SCO).
1128
1049f94e
AM
1129So everything works fine when not producing relocatable output. When
1130we are producing relocatable output, logically we should do exactly
1131what we do when not producing relocatable output. Therefore, your
252b5132
RH
1132patch is correct. In fact, it should probably always just set
1133reloc_entry->addend to 0 for all cases, since it is, in fact, going to
1134add the value into the object file. This won't hurt the COFF code,
1135which doesn't use the addend; I'm not sure what it will do to other
1136formats (the thing to check for would be whether any formats both use
1137the addend and set partial_inplace).
1138
1049f94e 1139When I wanted to make coff-i386 produce relocatable output, I ran
252b5132
RH
1140into the problem that you are running into: I wanted to remove that
1141line. Rather than risk it, I made the coff-i386 relocs use a special
1142function; it's coff_i386_reloc in coff-i386.c. The function
1143specifically adds the addend field into the object file, knowing that
1144bfd_install_relocation is not going to. If you remove that line, then
1145coff-i386.c will wind up adding the addend field in twice. It's
1146trivial to fix; it just needs to be done.
1147
1148The problem with removing the line is just that it may break some
1149working code. With BFD it's hard to be sure of anything. The right
1150way to deal with this is simply to build and test at least all the
1151supported COFF targets. It should be straightforward if time and disk
1152space consuming. For each target:
1153 1) build the linker
1154 2) generate some executable, and link it using -r (I would
1155 probably use paranoia.o and link against newlib/libc.a, which
1156 for all the supported targets would be available in
1157 /usr/cygnus/progressive/H-host/target/lib/libc.a).
1158 3) make the change to reloc.c
1159 4) rebuild the linker
1160 5) repeat step 2
1161 6) if the resulting object files are the same, you have at least
1162 made it no worse
1163 7) if they are different you have to figure out which version is
b5f79c76 1164 right. */

1567 The insides of a reloc code. The idea is that, eventually, there
1568 will be one enumerator for every type of relocation we ever do.
1569 Pass one of these values to <<bfd_reloc_type_lookup>>, and it'll
1570 return a howto pointer.
1571
1572 This does mean that the application must determine the correct

1942 BFD_RELOC_ALPHA_LITUSE
1943ENUMDOC
1944 The Alpha LITERAL/LITUSE relocs are produced by a symbol reference;
1945 the assembler turns it into a LDQ instruction to load the address of
1946 the symbol, and then fills in a register in the real instruction.
1947
1948 The LITERAL reloc, at the LDQ instruction, refers to the .lita
1949 section symbol. The addend is ignored when writing, but is filled
1950 in with the file's GP value on reading, for convenience, as with the
1951 GPDISP_LO16 reloc.
1952
1953 The ELF_LITERAL reloc is somewhere between 16_GOTOFF and GPDISP_LO16.
1954 It should refer to the symbol to be referenced, as with 16_GOTOFF,
1955 but it generates output not based on the position within the .got
1956 section, but relative to the GP value chosen for the file during the
1957 final link stage.
1958
1959 The LITUSE reloc, on the instruction using the loaded address, gives
1960 information to the linker that it might be able to use to optimize
1961 away some literal section references. The symbol is ignored (read
1962 as the absolute section symbol), and the "addend" indicates the type
1963 of instruction using the register:
1964 1 - "memory" fmt insn
1965 2 - byte-manipulation (byte offset reg)
1966 3 - jsr (target of branch)

1970ENUMDOC
1971 The HINT relocation indicates a value that should be filled into the
1972 "hint" field of a jmp/jsr/ret instruction, for possible branch-
1973 prediction logic which may be provided on some processors.

88b6bae0 4086 These two relocations are used by the linker to determine which of
252b5132
RH
4087 the entries in a C++ virtual function table are actually used. When
4088 the --gc-sections option is given, the linker will zero out the entries
4089 that are not used, so that the code for those functions need not be
4090 included in the output.
4091
4092 VTABLE_INHERIT is a zero-space relocation used to describe to the
7dee875e 4093 linker the inheritance tree of a C++ virtual function table. The
252b5132
RH
4094 relocation's symbol should be the parent class' vtable, and the
4095 relocation should be located at the child vtable.
4096
4097 VTABLE_ENTRY is a zero-space relocation that describes the use of a
4098 virtual function table entry. The reloc's symbol should refer to the
4099 table of the class mentioned in the code. Off of that base, an offset
88b6bae0 4100 describes the entry that is being used. For Rela hosts, this offset
252b5132
RH
4101 is stored in the reloc's addend. For Rel hosts, we are forced to put
4102 this offset in the reloc's section offset.
