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

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.

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}.

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

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

1108
1109If you put a patch like that into BFD you need to check all the COFF
1110linkers. I am fairly certain that patch will break coff-i386 (e.g.,
1111SCO); see coff_i386_reloc in coff-i386.c where I worked around the
1112problem in a different way. There may very well be a reason that the
1113code works as it does.
1114
1115Hmmm. The first obvious point is that bfd_install_relocation should
1116not have any tests that depend upon the flavour. It's seem like
1117entirely the wrong place for such a thing. The second obvious point
1118is that the current code ignores the reloc addend when producing
1049f94e 1119relocatable output for COFF. That's peculiar. In fact, I really
252b5132
RH
1120have no idea what the point of the line you want to remove is.
1121
1122A typical COFF reloc subtracts the old value of the symbol and adds in
1123the new value to the location in the object file (if it's a pc
1124relative reloc it adds the difference between the symbol value and the
1125location). When relocating we need to preserve that property.
1126
1127BFD handles this by setting the addend to the negative of the old
1128value of the symbol. Unfortunately it handles common symbols in a
1129non-standard way (it doesn't subtract the old value) but that's a
1130different story (we can't change it without losing backward
1131compatibility with old object files) (coff-i386 does subtract the old
1132value, to be compatible with existing coff-i386 targets, like SCO).
1133
1049f94e
AM
1134So everything works fine when not producing relocatable output. When
1135we are producing relocatable output, logically we should do exactly
1136what we do when not producing relocatable output. Therefore, your
252b5132
RH
1137patch is correct. In fact, it should probably always just set
1138reloc_entry->addend to 0 for all cases, since it is, in fact, going to
1139add the value into the object file. This won't hurt the COFF code,
1140which doesn't use the addend; I'm not sure what it will do to other
1141formats (the thing to check for would be whether any formats both use
1142the addend and set partial_inplace).
1143
1049f94e 1144When I wanted to make coff-i386 produce relocatable output, I ran
252b5132
RH
1145into the problem that you are running into: I wanted to remove that
1146line. Rather than risk it, I made the coff-i386 relocs use a special
1147function; it's coff_i386_reloc in coff-i386.c. The function
1148specifically adds the addend field into the object file, knowing that
1149bfd_install_relocation is not going to. If you remove that line, then
1150coff-i386.c will wind up adding the addend field in twice. It's
1151trivial to fix; it just needs to be done.
1152
1153The problem with removing the line is just that it may break some
1154working code. With BFD it's hard to be sure of anything. The right
1155way to deal with this is simply to build and test at least all the
1156supported COFF targets. It should be straightforward if time and disk
1157space consuming. For each target:
1158 1) build the linker
1159 2) generate some executable, and link it using -r (I would
1160 probably use paranoia.o and link against newlib/libc.a, which
1161 for all the supported targets would be available in
1162 /usr/cygnus/progressive/H-host/target/lib/libc.a).
1163 3) make the change to reloc.c
1164 4) rebuild the linker
1165 5) repeat step 2
1166 6) if the resulting object files are the same, you have at least
1167 made it no worse
1168 7) if they are different you have to figure out which version is
b5f79c76 1169 right. */

1950 the symbol, and then fills in a register in the real instruction.
1951
1952 The LITERAL reloc, at the LDQ instruction, refers to the .lita
1953 section symbol. The addend is ignored when writing, but is filled
1954 in with the file's GP value on reading, for convenience, as with the
1955 GPDISP_LO16 reloc.
1956
1957 The ELF_LITERAL reloc is somewhere between 16_GOTOFF and GPDISP_LO16.
1958 It should refer to the symbol to be referenced, as with 16_GOTOFF,
1959 but it generates output not based on the position within the .got
1960 section, but relative to the GP value chosen for the file during the
1961 final link stage.
1962
1963 The LITUSE reloc, on the instruction using the loaded address, gives
1964 information to the linker that it might be able to use to optimize
1965 away some literal section references. The symbol is ignored (read
1966 as the absolute section symbol), and the "addend" indicates the type
1967 of instruction using the register:
1968 1 - "memory" fmt insn
1969 2 - byte-manipulation (byte offset reg)
1970 3 - jsr (target of branch)

88b6bae0 3743 These two relocations are used by the linker to determine which of
252b5132
RH
3744 the entries in a C++ virtual function table are actually used. When
3745 the --gc-sections option is given, the linker will zero out the entries
3746 that are not used, so that the code for those functions need not be
3747 included in the output.
3748
3749 VTABLE_INHERIT is a zero-space relocation used to describe to the
7dee875e 3750 linker the inheritance tree of a C++ virtual function table. The
252b5132
RH
3751 relocation's symbol should be the parent class' vtable, and the
3752 relocation should be located at the child vtable.
3753
3754 VTABLE_ENTRY is a zero-space relocation that describes the use of a
3755 virtual function table entry. The reloc's symbol should refer to the
3756 table of the class mentioned in the code. Off of that base, an offset
88b6bae0 3757 describes the entry that is being used. For Rela hosts, this offset
252b5132
RH
3758 is stored in the reloc's addend. For Rel hosts, we are forced to put
3759 this offset in the reloc's section offset.
