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. 241 242 */ 243 244 /* 245 SUBSUBSECTION 246 <<enum complain_overflow>> 247 248 Indicates what sort of overflow checking should be done when 249 performing a relocation. 250 251 CODE_FRAGMENT 252 . 253 .enum complain_overflow 254 .{ 255 . {* Do not complain on overflow. *} 256 . complain_overflow_dont, 257 . 258 . {* Complain if the value overflows when considered as a signed 259 . number one bit larger than the field. ie.

Some targets arrange for 661 the addend to be the negative of the position of the location 662 within the section; for example, i386-aout does this. For 663 i386-aout, pcrel_offset is FALSE. Some other targets do not 664 include the position of the location; for example, m88kbcs, 665 or ELF. For those targets, pcrel_offset is TRUE. 666 667 If we are producing relocatable output, then we must ensure 668 that this reloc will be correctly computed when the final 669 relocation is done. If pcrel_offset is FALSE we want to wind 670 up with the negative of the location within the section, 671 which means we must adjust the existing addend by the change 672 in the location within the section. If pcrel_offset is TRUE 673 we do not want to adjust the existing addend at all. 674 675 FIXME: This seems logical to me, but for the case of 676 producing relocatable output it is not what the code 677 actually does.

Removing the line below this comment 715 fixes that problem; see PR 2953. 716 717 However, Ian wrote the following, regarding removing the line below, 718 which explains why it is still enabled: --djm 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 781 */ 782 relocation -= reloc_entry->addend; 783 reloc_entry->addend = 0; 784 } 785 else 786 { 787 reloc_entry->addend = relocation; 788 } 789 } 790 } 791 else 792 { 793 reloc_entry->addend = 0; 794 } 795 796 /* FIXME: This overflow checking is incomplete, because the value 797 might have overflowed before we get here.

When 4205 the --gc-sections option is given, the linker will zero out the entries 4206 that are not used, so that the code for those functions need not be 4207 included in the output. 4208 4209 VTABLE_INHERIT is a zero-space relocation used to describe to the 4210 linker the inheritance tree of a C++ virtual function table. The 4211 relocation's symbol should be the parent class' vtable, and the 4212 relocation should be located at the child vtable. 4213 4214 VTABLE_ENTRY is a zero-space relocation that describes the use of a 4215 virtual function table entry. The reloc's symbol should refer to the 4216 table of the class mentioned in the code. Off of that base, an offset 4217 describes the entry that is being used. For Rela hosts, this offset 4218 is stored in the reloc's addend.
