| 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. | |||

| 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 | |||

| 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. */ | |||

| 1600 | DESCRIPTION | |||
| 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. | |||

| 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. | |||
