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. | |||

117 | /* | |||
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. | |||

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}. | |||

722 | fixes that problem; see PR 2953. | |||
723 | ||||
724 | However, Ian wrote the following, regarding removing the line below, | |||
725 | which explains why it is still enabled: --djm | |||
726 | ||||
727 | If you put a patch like that into BFD you need to check all the COFF | |||
728 | linkers. I am fairly certain that patch will break coff-i386 (e.g., | |||
729 | SCO); see coff_i386_reloc in coff-i386.c where I worked around the | |||
730 | problem in a different way. There may very well be a reason that the | |||
731 | code works as it does. | |||
732 | ||||
733 | Hmmm. The first obvious point is that bfd_perform_relocation should | |||
734 | not have any tests that depend upon the flavour. It's seem like | |||
735 | entirely the wrong place for such a thing. The second obvious point | |||
736 | is that the current code ignores the reloc addend when producing | |||
737 | relocatable output for COFF. That's peculiar. In fact, I really | |||
738 | have no idea what the point of the line you want to remove is. | |||
739 | ||||
740 | A typical COFF reloc subtracts the old value of the symbol and adds in | |||
741 | the new value to the location in the object file (if it's a pc | |||
742 | relative reloc it adds the difference between the symbol value and the | |||
743 | location). When relocating we need to preserve that property. | |||
744 | ||||
745 | BFD handles this by setting the addend to the negative of the old | |||
746 | value of the symbol. Unfortunately it handles common symbols in a | |||
747 | non-standard way (it doesn't subtract the old value) but that's a | |||
748 | different story (we can't change it without losing backward | |||
749 | compatibility with old object files) (coff-i386 does subtract the old | |||
750 | value, to be compatible with existing coff-i386 targets, like SCO). | |||
751 | ||||
752 | So everything works fine when not producing relocatable output. When | |||
753 | we are producing relocatable output, logically we should do exactly | |||
754 | what we do when not producing relocatable output. Therefore, your | |||
755 | patch is correct. In fact, it should probably always just set | |||
756 | reloc_entry->addend to 0 for all cases, since it is, in fact, going to | |||
757 | add the value into the object file. This won't hurt the COFF code, | |||
758 | which doesn't use the addend; I'm not sure what it will do to other | |||
759 | formats (the thing to check for would be whether any formats both use | |||
760 | the addend and set partial_inplace). | |||
761 | ||||
762 | When I wanted to make coff-i386 produce relocatable output, I ran | |||
763 | into the problem that you are running into: I wanted to remove that | |||
764 | line. Rather than risk it, I made the coff-i386 relocs use a special | |||
765 | function; it's coff_i386_reloc in coff-i386.c. The function | |||
766 | specifically adds the addend field into the object file, knowing that | |||
767 | bfd_perform_relocation is not going to. If you remove that line, then | |||
768 | coff-i386.c will wind up adding the addend field in twice. It's | |||
769 | trivial to fix; it just needs to be done. | |||
770 | ||||
771 | The problem with removing the line is just that it may break some | |||
772 | working code. With BFD it's hard to be sure of anything. The right | |||
773 | way to deal with this is simply to build and test at least all the | |||
774 | supported COFF targets. It should be straightforward if time and disk | |||
775 | space 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 | |||

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

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. | |||

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 | |||
1971 | 2 - byte-manipulation (byte offset reg) | |||

3540 | ENUMDOC | |||
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. | |||
