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.

562 DESCRIPTION
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.

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

1120 have no idea what the point of the line you want to remove is.
1121
1122 A typical COFF reloc subtracts the old value of the symbol and adds in
1123 the new value to the location in the object file (if it's a pc
1124 relative reloc it adds the difference between the symbol value and the
1125 location). When relocating we need to preserve that property.
1126
1127 BFD handles this by setting the addend to the negative of the old
1128 value of the symbol. Unfortunately it handles common symbols in a
1129 non-standard way (it doesn't subtract the old value) but that's a
1130 different story (we can't change it without losing backward
1131 compatibility with old object files) (coff-i386 does subtract the old
1132 value, to be compatible with existing coff-i386 targets, like SCO).
1133
1134 So everything works fine when not producing relocatable output. When
1135 we are producing relocatable output, logically we should do exactly
1136 what we do when not producing relocatable output. Therefore, your
1137 patch is correct. In fact, it should probably always just set
1138 reloc_entry->addend to 0 for all cases, since it is, in fact, going to
1139 add the value into the object file. This won't hurt the COFF code,
1140 which doesn't use the addend; I'm not sure what it will do to other
1141 formats (the thing to check for would be whether any formats both use
1142 the addend and set partial_inplace).
1143
1144 When I wanted to make coff-i386 produce relocatable output, I ran
1145 into the problem that you are running into: I wanted to remove that
1146 line. Rather than risk it, I made the coff-i386 relocs use a special
1147 function; it's coff_i386_reloc in coff-i386.c. The function
1148 specifically adds the addend field into the object file, knowing that
1149 bfd_install_relocation is not going to. If you remove that line, then
1150 coff-i386.c will wind up adding the addend field in twice. It's
1151 trivial to fix; it just needs to be done.
1152
1153 The problem with removing the line is just that it may break some
1154 working code. With BFD it's hard to be sure of anything. The right
1155 way to deal with this is simply to build and test at least all the
1156 supported COFF targets. It should be straightforward if time and disk
1157 space 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
1169 right. */

1598 The insides of a reloc code. The idea is that, eventually, there
1599 will be one enumerator for every type of relocation we ever do.
1600 Pass one of these values to <<bfd_reloc_type_lookup>>, and it'll
1601 return a howto pointer.
1602
1603 This does mean that the application must determine the correct
1604 enumerator value; you can't get a howto pointer from a random set
1605 of attributes.

1920 Alpha ECOFF and ELF relocations. Some of these treat the symbol or
1921 "addend" in some special way.
1922 For GPDISP_HI16 ("gpdisp") relocations, the symbol is ignored when
1923 writing; when reading, it will be the absolute section symbol. The
1924 addend is the displacement in bytes of the "lda" instruction from
1925 the "ldah" instruction (which is at the address of this reloc).
1926 ENUM
1927 BFD_RELOC_ALPHA_GPDISP_LO16

1929 For GPDISP_LO16 ("ignore") relocations, the symbol is handled as

1931 relocations out, and is filled in with the file's GP value on
1932 reading, for convenience.

1947 ENUMDOC
1948 The Alpha LITERAL/LITUSE relocs are produced by a symbol reference;
1949 the assembler turns it into a LDQ instruction to load the address of
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)

3875 ENUMDOC
3876 These two relocations are used by the linker to determine which of
3877 the entries in a C++ virtual function table are actually used. When
3878 the --gc-sections option is given, the linker will zero out the entries
3879 that are not used, so that the code for those functions need not be
3880 included in the output.
3881
3882 VTABLE_INHERIT is a zero-space relocation used to describe to the
3883 linker the inheritance tree of a C++ virtual function table. The
3884 relocation's symbol should be the parent class' vtable, and the
3885 relocation should be located at the child vtable.
3886
3887 VTABLE_ENTRY is a zero-space relocation that describes the use of a
3888 virtual function table entry. The reloc's symbol should refer to the
3889 table of the class mentioned in the code. Off of that base, an offset
3890 describes the entry that is being used. For Rela hosts, this offset
3891 is stored in the reloc's addend. For Rel hosts, we are forced to put
3892 this offset in the reloc's section offset.
