It is the pointer 127 into the table returned by the back end's 128 <<canonicalize_symtab>> action. @xref{Symbols}. The symbol is 129 referenced through a pointer to a pointer so that tools like 130 the linker can fix up all the symbols of the same name by 131 modifying only one pointer. The relocation routine looks in 132 the symbol and uses the base of the section the symbol is 133 attached to and the value of the symbol as the initial 134 relocation offset. If the symbol pointer is zero, then the 135 section provided is looked up. 136 137 o <<address>> 138 139 The <<address>> field gives the offset in bytes from the base of 140 the section data which owns the relocation record to the first 141 byte of relocatable information. The actual data relocated 142 will be relative to this point; for example, a relocation 143 type which modifies the bottom two bytes of a four byte word 144 would not touch the first byte pointed to in a big endian 145 world. 146 147 o <<addend>> 148 149 The <<addend>> is a value provided by the back end to be added (!) 150 to the relocation offset. Its interpretation is dependent upon 151 the howto. For example, on the 68k the code: 152 153 | char foo[]; 154 | main() 155 | { 156 | return foo[0x12345678]; 157 | } 158 159 Could be compiled into: 160 161 | linkw fp,#-4 162 | moveb @@#12345678,d0 163 | extbl d0 164 | unlk fp 165 | rts 166 167 This could create a reloc pointing to <<foo>>, but leave the 168 offset in the data, something like: 169 170 |RELOCATION RECORDS FOR [.text]: 171 |offset type value 172 |00000006 32 _foo 173 | 174 |00000000 4e56 fffc ; linkw fp,#-4 175 |00000004 1039 1234 5678 ; moveb @@#12345678,d0 176 |0000000a 49c0 ; extbl d0 177 |0000000c 4e5e ; unlk fp 178 |0000000e 4e75 ; rts 179 180 Using coff and an 88k, some instructions don't have enough 181 space in them to represent the full address range, and 182 pointers have to be loaded in two parts. So you'd get something like: 183 184 | or.u r13,r0,hi16(_foo+0x12345678) 185 | ld.b r2,r13,lo16(_foo+0x12345678) 186 | jmp r1 187 188 This should create two relocs, both pointing to <<_foo>>, and with 189 0x12340000 in their addend field. The data would consist of: 190 191 |RELOCATION RECORDS FOR [.text]: 192 |offset type value 193 |00000002 HVRT16 _foo+0x12340000 194 |00000006 LVRT16 _foo+0x12340000 195 | 196 |00000000 5da05678 ; or.u r13,r0,0x5678 197 |00000004 1c4d5678 ; ld.b r2,r13,0x5678 198 |00000008 f400c001 ; jmp r1 199 200 The relocation routine digs out the value from the data, adds 201 it to the addend to get the original offset, and then adds the 202 value of <<_foo>>. Note that all 32 bits have to be kept around 203 somewhere, to cope with carry from bit 15 to bit 16. 204 205 One further example is the sparc and the a.out format. The 206 sparc has a similar problem to the 88k, in that some 207 instructions don't have room for an entire offset, but on the 208 sparc the parts are created in odd sized lumps. The designers of 209 the a.out format chose to not use the data within the section 210 for storing part of the offset; all the offset is kept within 211 the reloc. Anything in the data should be ignored. 212 213 | save %sp,-112,%sp 214 | sethi %hi(_foo+0x12345678),%g2 215 | ldsb [%g2+%lo(_foo+0x12345678)],%i0 216 | ret 217 | restore 218 219 Both relocs contain a pointer to <<foo>>, and the offsets 220 contain junk. 221 222 |RELOCATION RECORDS FOR [.text]: 223 |offset type value 224 |00000004 HI22 _foo+0x12345678 225 |00000008 LO10 _foo+0x12345678 226 | 227 |00000000 9de3bf90 ; save %sp,-112,%sp 228 |00000004 05000000 ; sethi %hi(_foo+0),%g2 229 |00000008 f048a000 ; ldsb [%g2+%lo(_foo+0)],%i0 230 |0000000c 81c7e008 ; ret 231 |00000010 81e80000 ; restore 232 233 o <<howto>> 234 235 The <<howto>> field can be imagined as a 236 relocation instruction. It is a pointer to a structure which 237 contains information on what to do with all of the other 238 information in the reloc record and data section. A back end 239 would normally have a relocation instruction set and turn 240 relocations into pointers to the correct structure on input - 241 but it would be possible to create each howto field on demand. 242 243 */ 244 245 /* 246 SUBSUBSECTION 247 <<enum complain_overflow>> 248 249 Indicates what sort of overflow checking should be done when 250 performing a relocation. 251 252 CODE_FRAGMENT 253 . 254 .enum complain_overflow 255 .{ 256 . {* Do not complain on overflow. *} 257 . complain_overflow_dont, 258 . 259 . {* Complain if the value overflows when considered as a signed 260 . number one bit larger than the field. ie.

Some targets arrange for 659 the addend to be the negative of the position of the location 660 within the section; for example, i386-aout does this. For 661 i386-aout, pcrel_offset is FALSE. Some other targets do not 662 include the position of the location; for example, m88kbcs, 663 or ELF. For those targets, pcrel_offset is TRUE. 664 665 If we are producing relocatable output, then we must ensure 666 that this reloc will be correctly computed when the final 667 relocation is done. If pcrel_offset is FALSE we want to wind 668 up with the negative of the location within the section, 669 which means we must adjust the existing addend by the change 670 in the location within the section. If pcrel_offset is TRUE 671 we do not want to adjust the existing addend at all. 672 673 FIXME: This seems logical to me, but for the case of 674 producing relocatable output it is not what the code 675 actually does.

Removing the line below this comment 713 fixes that problem; see PR 2953. 714 715 However, Ian wrote the following, regarding removing the line below, 716 which explains why it is still enabled: --djm 717 718 If you put a patch like that into BFD you need to check all the COFF 719 linkers. I am fairly certain that patch will break coff-i386 (e.g., 720 SCO); see coff_i386_reloc in coff-i386.c where I worked around the 721 problem in a different way. There may very well be a reason that the 722 code works as it does. 723 724 Hmmm. The first obvious point is that bfd_perform_relocation should 725 not have any tests that depend upon the flavour. It's seem like 726 entirely the wrong place for such a thing. The second obvious point 727 is that the current code ignores the reloc addend when producing 728 relocatable output for COFF. That's peculiar. In fact, I really 729 have no idea what the point of the line you want to remove is. 730 731 A typical COFF reloc subtracts the old value of the symbol and adds in 732 the new value to the location in the object file (if it's a pc 733 relative reloc it adds the difference between the symbol value and the 734 location). When relocating we need to preserve that property. 735 736 BFD handles this by setting the addend to the negative of the old 737 value of the symbol. Unfortunately it handles common symbols in a 738 non-standard way (it doesn't subtract the old value) but that's a 739 different story (we can't change it without losing backward 740 compatibility with old object files) (coff-i386 does subtract the old 741 value, to be compatible with existing coff-i386 targets, like SCO). 742 743 So everything works fine when not producing relocatable output. When 744 we are producing relocatable output, logically we should do exactly 745 what we do when not producing relocatable output. Therefore, your 746 patch is correct. In fact, it should probably always just set 747 reloc_entry->addend to 0 for all cases, since it is, in fact, going to 748 add the value into the object file. This won't hurt the COFF code, 749 which doesn't use the addend; I'm not sure what it will do to other 750 formats (the thing to check for would be whether any formats both use 751 the addend and set partial_inplace). 752 753 When I wanted to make coff-i386 produce relocatable output, I ran 754 into the problem that you are running into: I wanted to remove that 755 line. Rather than risk it, I made the coff-i386 relocs use a special 756 function; it's coff_i386_reloc in coff-i386.c. The function 757 specifically adds the addend field into the object file, knowing that 758 bfd_perform_relocation is not going to. If you remove that line, then 759 coff-i386.c will wind up adding the addend field in twice. It's 760 trivial to fix; it just needs to be done. 761 762 The problem with removing the line is just that it may break some 763 working code. With BFD it's hard to be sure of anything. The right 764 way to deal with this is simply to build and test at least all the 765 supported COFF targets. It should be straightforward if time and disk 766 space consuming. For each target: 767 1) build the linker 768 2) generate some executable, and link it using -r (I would 769 probably use paranoia.o and link against newlib/libc.a, which 770 for all the supported targets would be available in 771 /usr/cygnus/progressive/H-host/target/lib/libc.a). 772 3) make the change to reloc.c 773 4) rebuild the linker 774 5) repeat step 2 775 6) if the resulting object files are the same, you have at least 776 made it no worse 777 7) if they are different you have to figure out which version is 778 right 779 */ 780 relocation -= reloc_entry->addend; 781 reloc_entry->addend = 0; 782 } 783 else 784 { 785 reloc_entry->addend = relocation; 786 } 787 } 788 } 789 else 790 { 791 reloc_entry->addend = 0; 792 } 793 794 /* FIXME: This overflow checking is incomplete, because the value 795 might have overflowed before we get here.

When 4569 the --gc-sections option is given, the linker will zero out the entries 4570 that are not used, so that the code for those functions need not be 4571 included in the output. 4572 4573 VTABLE_INHERIT is a zero-space relocation used to describe to the 4574 linker the inheritance tree of a C++ virtual function table. The 4575 relocation's symbol should be the parent class' vtable, and the 4576 relocation should be located at the child vtable. 4577 4578 VTABLE_ENTRY is a zero-space relocation that describes the use of a 4579 virtual function table entry. The reloc's symbol should refer to the 4580 table of the class mentioned in the code. Off of that base, an offset 4581 describes the entry that is being used. For Rela hosts, this offset 4582 is stored in the reloc's addend.
