24 SECTION
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.

118 DESCRIPTION
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.

555 char **error_message);
556
557 DESCRIPTION
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

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

1118 the new value to the location in the object file (if it's a pc
1119 relative reloc it adds the difference between the symbol value and the
1120 location). When relocating we need to preserve that property.
1121
1122 BFD handles this by setting the addend to the negative of the old
1123 value of the symbol. Unfortunately it handles common symbols in a
1124 non-standard way (it doesn't subtract the old value) but that's a
1125 different story (we can't change it without losing backward
1126 compatibility with old object files) (coff-i386 does subtract the old
1127 value, to be compatible with existing coff-i386 targets, like SCO).
1128
1129 So everything works fine when not producing relocatable output. When
1130 we are producing relocatable output, logically we should do exactly
1131 what we do when not producing relocatable output. Therefore, your
1132 patch is correct. In fact, it should probably always just set
1133 reloc_entry->addend to 0 for all cases, since it is, in fact, going to
1134 add the value into the object file. This won't hurt the COFF code,
1135 which doesn't use the addend; I'm not sure what it will do to other
1136 formats (the thing to check for would be whether any formats both use
1137 the addend and set partial_inplace).
1138
1139 When I wanted to make coff-i386 produce relocatable output, I ran
1140 into the problem that you are running into: I wanted to remove that
1141 line. Rather than risk it, I made the coff-i386 relocs use a special
1142 function; it's coff_i386_reloc in coff-i386.c. The function
1143 specifically adds the addend field into the object file, knowing that
1144 bfd_install_relocation is not going to. If you remove that line, then
1145 coff-i386.c will wind up adding the addend field in twice. It's
1146 trivial to fix; it just needs to be done.
1147
1148 The problem with removing the line is just that it may break some
1149 working code. With BFD it's hard to be sure of anything. The right
1150 way to deal with this is simply to build and test at least all the
1151 supported COFF targets. It should be straightforward if time and disk
1152 space 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
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

1704 i.e., byte displacements shifted right two bits. The 30-bit word
1705 displacement (<<32_PCREL_S2>> -- 32 bits, shifted 2) is used on the
1706 SPARC. (SPARC tools generally refer to this as <<WDISP30>>.) The
1707 signed 16-bit displacement is used on the MIPS, and the 23-bit

1889 Alpha ECOFF and ELF relocations. Some of these treat the symbol or
1890 "addend" in some special way.
1891 For GPDISP_HI16 ("gpdisp") relocations, the symbol is ignored when
1892 writing; when reading, it will be the absolute section symbol. The
1893 addend is the displacement in bytes of the "lda" instruction from
1894 the "ldah" instruction (which is at the address of this reloc).
1895 ENUM
1896 BFD_RELOC_ALPHA_GPDISP_LO16
1897 ENUMDOC
1898 For GPDISP_LO16 ("ignore") relocations, the symbol is handled as
1899 with GPDISP_HI16 relocs. The addend is ignored when writing the
1900 relocations out, and is filled in with the file's GP value on
1901 reading, for convenience.

1915 BFD_RELOC_ALPHA_LITUSE
1916 ENUMDOC
1917 The Alpha LITERAL/LITUSE relocs are produced by a symbol reference;
1918 the assembler turns it into a LDQ instruction to load the address of
1919 the symbol, and then fills in a register in the real instruction.
1920
1921 The LITERAL reloc, at the LDQ instruction, refers to the .lita
1922 section symbol. The addend is ignored when writing, but is filled
1923 in with the file's GP value on reading, for convenience, as with the
1924 GPDISP_LO16 reloc.
1925
1926 The ELF_LITERAL reloc is somewhere between 16_GOTOFF and GPDISP_LO16.
1927 It should refer to the symbol to be referenced, as with 16_GOTOFF,
1928 but it generates output not based on the position within the .got
1929 section, but relative to the GP value chosen for the file during the
1930 final link stage.
1931
1932 The LITUSE reloc, on the instruction using the loaded address, gives
1933 information to the linker that it might be able to use to optimize
1934 away some literal section references. The symbol is ignored (read
1935 as the absolute section symbol), and the "addend" indicates the type
1936 of instruction using the register:
1937 1 - "memory" fmt insn
1938 2 - byte-manipulation (byte offset reg)
1939 3 - jsr (target of branch)

4019 ENUMDOC
4020 These two relocations are used by the linker to determine which of
4021 the entries in a C++ virtual function table are actually used. When
4022 the --gc-sections option is given, the linker will zero out the entries
4023 that are not used, so that the code for those functions need not be
4024 included in the output.
4025
4026 VTABLE_INHERIT is a zero-space relocation used to describe to the
4027 linker the inheritance tree of a C++ virtual function table. The
4028 relocation's symbol should be the parent class' vtable, and the
4029 relocation should be located at the child vtable.
4030
4031 VTABLE_ENTRY is a zero-space relocation that describes the use of a
4032 virtual function table entry. The reloc's symbol should refer to the
4033 table of the class mentioned in the code. Off of that base, an offset
4034 describes the entry that is being used. For Rela hosts, this offset
4035 is stored in the reloc's addend. For Rel hosts, we are forced to put
4036 this offset in the reloc's section offset.
