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.

The addend is ignored when writing, but is filled 1927 in with the file's GP value on reading, for convenience, as with the 1928 GPDISP_LO16 reloc. 1929 1930 The ELF_LITERAL reloc is somewhere between 16_GOTOFF and GPDISP_LO16. 1931 It should refer to the symbol to be referenced, as with 16_GOTOFF, 1932 but it generates output not based on the position within the .got 1933 section, but relative to the GP value chosen for the file during the 1934 final link stage. 1935 1936 The LITUSE reloc, on the instruction using the loaded address, gives 1937 information to the linker that it might be able to use to optimize 1938 away some literal section references.

When 3943 the --gc-sections option is given, the linker will zero out the entries 3944 that are not used, so that the code for those functions need not be 3945 included in the output. 3946 3947 VTABLE_INHERIT is a zero-space relocation used to describe to the 3948 linker the inheritance tree of a C++ virtual function table. The 3949 relocation's symbol should be the parent class' vtable, and the 3950 relocation should be located at the child vtable. 3951 3952 VTABLE_ENTRY is a zero-space relocation that describes the use of a 3953 virtual function table entry. The reloc's symbol should refer to the 3954 table of the class mentioned in the code. Off of that base, an offset 3955 describes the entry that is being used. For Rela hosts, this offset 3956 is stored in the reloc's addend. For Rel hosts, we are forced to put 3957 this offset in the reloc's section offset. 3958 3959 ENUM 3960 BFD_RELOC_IA64_IMM14 3961 ENUMX 3962 BFD_RELOC_IA64_IMM22 3963 ENUMX 3964 BFD_RELOC_IA64_IMM64 3965 ENUMX 3966 BFD_RELOC_IA64_DIR32MSB 3967 ENUMX 3968 BFD_RELOC_IA64_DIR32LSB 3969 ENUMX 3970 BFD_RELOC_IA64_DIR64MSB 3971 ENUMX 3972 BFD_RELOC_IA64_DIR64LSB 3973 ENUMX 3974 BFD_RELOC_IA64_GPREL22 3975 ENUMX 3976 BFD_RELOC_IA64_GPREL64I 3977 ENUMX 3978 BFD_RELOC_IA64_GPREL32MSB 3979 ENUMX 3980 BFD_RELOC_IA64_GPREL32LSB 3981 ENUMX 3982 BFD_RELOC_IA64_GPREL64MSB 3983 ENUMX 3984 BFD_RELOC_IA64_GPREL64LSB 3985 ENUMX 3986 BFD_RELOC_IA64_LTOFF22 3987 ENUMX 3988 BFD_RELOC_IA64_LTOFF64I 3989 ENUMX 3990 BFD_RELOC_IA64_PLTOFF22 3991 ENUMX 3992 BFD_RELOC_IA64_PLTOFF64I 3993 ENUMX 3994 BFD_RELOC_IA64_PLTOFF64MSB 3995 ENUMX 3996 BFD_RELOC_IA64_PLTOFF64LSB 3997 ENUMX 3998 BFD_RELOC_IA64_FPTR64I 3999 ENUMX 4000 BFD_RELOC_IA64_FPTR32MSB 4001 ENUMX 4002 BFD_RELOC_IA64_FPTR32LSB 4003 ENUMX 4004 BFD_RELOC_IA64_FPTR64MSB 4005 ENUMX 4006 BFD_RELOC_IA64_FPTR64LSB 4007 ENUMX 4008 BFD_RELOC_IA64_PCREL21B 4009 ENUMX 4010 BFD_RELOC_IA64_PCREL21BI 4011 ENUMX 4012 BFD_RELOC_IA64_PCREL21M 4013 ENUMX 4014 BFD_RELOC_IA64_PCREL21F 4015 ENUMX 4016 BFD_RELOC_IA64_PCREL22 4017 ENUMX 4018 BFD_RELOC_IA64_PCREL60B 4019 ENUMX 4020 BFD_RELOC_IA64_PCREL64I 4021 ENUMX 4022 BFD_RELOC_IA64_PCREL32MSB 4023 ENUMX 4024 BFD_RELOC_IA64_PCREL32LSB 4025 ENUMX 4026 BFD_RELOC_IA64_PCREL64MSB 4027 ENUMX 4028 BFD_RELOC_IA64_PCREL64LSB 4029 ENUMX 4030 BFD_RELOC_IA64_LTOFF_FPTR22 4031 ENUMX 4032 BFD_RELOC_IA64_LTOFF_FPTR64I 4033 ENUMX 4034 BFD_RELOC_IA64_LTOFF_FPTR32MSB 4035 ENUMX 4036 BFD_RELOC_IA64_LTOFF_FPTR32LSB 4037 ENUMX 4038 BFD_RELOC_IA64_LTOFF_FPTR64MSB 4039 ENUMX 4040 BFD_RELOC_IA64_LTOFF_FPTR64LSB 4041 ENUMX 4042 BFD_RELOC_IA64_SEGREL32MSB 4043 ENUMX 4044 BFD_RELOC_IA64_SEGREL32LSB 4045 ENUMX 4046 BFD_RELOC_IA64_SEGREL64MSB 4047 ENUMX 4048 BFD_RELOC_IA64_SEGREL64LSB 4049 ENUMX 4050 BFD_RELOC_IA64_SECREL32MSB 4051 ENUMX 4052 BFD_RELOC_IA64_SECREL32LSB 4053 ENUMX 4054 BFD_RELOC_IA64_SECREL64MSB 4055 ENUMX 4056 BFD_RELOC_IA64_SECREL64LSB 4057 ENUMX 4058 BFD_RELOC_IA64_REL32MSB 4059 ENUMX 4060 BFD_RELOC_IA64_REL32LSB 4061 ENUMX 4062 BFD_RELOC_IA64_REL64MSB 4063 ENUMX 4064 BFD_RELOC_IA64_REL64LSB 4065 ENUMX 4066 BFD_RELOC_IA64_LTV32MSB 4067 ENUMX 4068 BFD_RELOC_IA64_LTV32LSB 4069 ENUMX 4070 BFD_RELOC_IA64_LTV64MSB 4071 ENUMX 4072 BFD_RELOC_IA64_LTV64LSB 4073 ENUMX 4074 BFD_RELOC_IA64_IPLTMSB 4075 ENUMX 4076 BFD_RELOC_IA64_IPLTLSB 4077 ENUMX 4078 BFD_RELOC_IA64_COPY 4079 ENUMX 4080 BFD_RELOC_IA64_LTOFF22X 4081 ENUMX 4082 BFD_RELOC_IA64_LDXMOV 4083 ENUMX 4084 BFD_RELOC_IA64_TPREL14 4085 ENUMX 4086 BFD_RELOC_IA64_TPREL22 4087 ENUMX 4088 BFD_RELOC_IA64_TPREL64I 4089 ENUMX 4090 BFD_RELOC_IA64_TPREL64MSB 4091 ENUMX 4092 BFD_RELOC_IA64_TPREL64LSB 4093 ENUMX 4094 BFD_RELOC_IA64_LTOFF_TPREL22 4095 ENUMX 4096 BFD_RELOC_IA64_DTPMOD64MSB 4097 ENUMX 4098 BFD_RELOC_IA64_DTPMOD64LSB 4099 ENUMX 4100 BFD_RELOC_IA64_LTOFF_DTPMOD22 4101 ENUMX 4102 BFD_RELOC_IA64_DTPREL14 4103 ENUMX 4104 BFD_RELOC_IA64_DTPREL22 4105 ENUMX 4106 BFD_RELOC_IA64_DTPREL64I 4107 ENUMX 4108 BFD_RELOC_IA64_DTPREL32MSB 4109 ENUMX 4110 BFD_RELOC_IA64_DTPREL32LSB 4111 ENUMX 4112 BFD_RELOC_IA64_DTPREL64MSB 4113 ENUMX 4114 BFD_RELOC_IA64_DTPREL64LSB 4115 ENUMX 4116 BFD_RELOC_IA64_LTOFF_DTPREL22 4117 ENUMDOC 4118 Intel IA64 Relocations. 4119 4120 ENUM 4121 BFD_RELOC_M68HC11_HI8 4122 ENUMDOC 4123 Motorola 68HC11 reloc. 4124 This is the 8 bit high part of an absolute address. 4125 ENUM 4126 BFD_RELOC_M68HC11_LO8 4127 ENUMDOC 4128 Motorola 68HC11 reloc. 4129 This is the 8 bit low part of an absolute address. 4130 ENUM 4131 BFD_RELOC_M68HC11_3B 4132 ENUMDOC 4133 Motorola 68HC11 reloc. 4134 This is the 3 bit of a value. 4135 ENUM 4136 BFD_RELOC_M68HC11_RL_JUMP 4137 ENUMDOC 4138 Motorola 68HC11 reloc. 4139 This reloc marks the beginning of a jump/call instruction. 4140 It is used for linker relaxation to correctly identify beginning 4141 of instruction and change some branches to use PC-relative 4142 addressing mode. 4143 ENUM 4144 BFD_RELOC_M68HC11_RL_GROUP 4145 ENUMDOC 4146 Motorola 68HC11 reloc. 4147 This reloc marks a group of several instructions that gcc generates 4148 and for which the linker relaxation pass can modify and/or remove 4149 some of them. 4150 ENUM 4151 BFD_RELOC_M68HC11_LO16 4152 ENUMDOC 4153 Motorola 68HC11 reloc. 4154 This is the 16-bit lower part of an address.
