  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.

 557 DESCRIPTION
 558         If @var{output_bfd} is supplied to this function, the
 559         generated image will be relocatable; the relocations are
 560         copied to the output file after they have been changed to
 561         reflect the new state of the world. There are two ways of
 562         reflecting the results of partial linkage in an output file:
 563         by modifying the output data in place, and by modifying the
 564         relocation record.  Some native formats (e.g., basic a.out and
 565         basic coff) have no way of specifying an addend in the
 566         relocation type, so the addend has to go in the output data.
 567         This is no big deal since in these formats the output data
 568         slot will always be big enough for the addend. Complex reloc
 569         types with addends were invented to solve just this problem.
 570         The @var{error_message} argument is set to an error message if
 571         this return @code{bfd_reloc_dangerous}.

 658
 659          If pcrel_offset is set, we must further subtract the position

 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.

 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

 949           (bfd *abfd,

 953            char **error_message);
 954
 955 DESCRIPTION
 956         This looks remarkably like <<bfd_perform_relocation>>, except it
 957         does not expect that the section contents have been filled in.
 958         I.e., it's suitable for use when creating, rather than applying
 959         a relocation.
 960
 961         For now, this function should be considered reserved for the
 962         assembler.

1041
1042          We start by subtracting the address of the section containing
1043          the location.
1044
1045          If pcrel_offset is set, we must further subtract the position
1046          of the location within the section.  Some targets arrange for
1047          the addend to be the negative of the position of the location
1048          within the section; for example, i386-aout does this.  For
1049          i386-aout, pcrel_offset is FALSE.  Some other targets do not
1050          include the position of the location; for example, m88kbcs,
1051          or ELF.  For those targets, pcrel_offset is TRUE.
1052
1053          If we are producing relocatable output, then we must ensure
1054          that this reloc will be correctly computed when the final
1055          relocation is done.  If pcrel_offset is FALSE we want to wind
1056          up with the negative of the location within the section,
1057          which means we must adjust the existing addend by the change
1058          in the location within the section.  If pcrel_offset is TRUE
1059          we do not want to adjust the existing addend at all.

1062          producing relocatable output it is not what the code

1100
1101 However, Ian wrote the following, regarding removing the line below,
1102 which explains why it is still enabled:  --djm
1103
1104 If you put a patch like that into BFD you need to check all the COFF
1105 linkers.  I am fairly certain that patch will break coff-i386 (e.g.,
1106 SCO); see coff_i386_reloc in coff-i386.c where I worked around the
1107 problem in a different way.  There may very well be a reason that the
1108 code works as it does.
1109
1110 Hmmm.  The first obvious point is that bfd_install_relocation should
1111 not have any tests that depend upon the flavour.  It's seem like
1112 entirely the wrong place for such a thing.  The second obvious point
1113 is that the current code ignores the reloc addend when producing
1114 relocatable output for COFF.  That's peculiar.  In fact, I really
1115 have no idea what the point of the line you want to remove is.
1116
1117 A typical COFF reloc subtracts the old value of the symbol and adds in
1118 the new value to the location in the object file (if it's a pc
1119 relative reloc it adds the difference between the symbol value and the
1120 location).  When relocating we need to preserve that property.
1121
1122 BFD handles this by setting the addend to the negative of the old
1123 value of the symbol.  Unfortunately it handles common symbols in a
1124 non-standard way (it doesn't subtract the old value) but that's a
1125 different story (we can't change it without losing backward
1126 compatibility with old object files) (coff-i386 does subtract the old
1127 value, to be compatible with existing coff-i386 targets, like SCO).
1128
1129 So everything works fine when not producing relocatable output.  When
1130 we are producing relocatable output, logically we should do exactly
1131 what we do when not producing relocatable output.  Therefore, your
1132 patch is correct.  In fact, it should probably always just set
1133 reloc_entry->addend to 0 for all cases, since it is, in fact, going to
1134 add the value into the object file.  This won't hurt the COFF code,
1135 which doesn't use the addend; I'm not sure what it will do to other
1136 formats (the thing to check for would be whether any formats both use
1137 the addend and set partial_inplace).
1138
1139 When I wanted to make coff-i386 produce relocatable output, I ran
1140 into the problem that you are running into: I wanted to remove that
1141 line.  Rather than risk it, I made the coff-i386 relocs use a special
1142 function; it's coff_i386_reloc in coff-i386.c.  The function
1143 specifically adds the addend field into the object file, knowing that
1144 bfd_install_relocation is not going to.  If you remove that line, then
1145 coff-i386.c will wind up adding the addend field in twice.  It's
1146 trivial to fix; it just needs to be done.
1147
1148 The problem with removing the line is just that it may break some
1149 working code.  With BFD it's hard to be sure of anything.  The right
1150 way to deal with this is simply to build and test at least all the
1151 supported COFF targets.  It should be straightforward if time and disk
1152 space consuming.  For each target:
1153     1) build the linker
1154     2) generate some executable, and link it using -r (I would
1155        probably use paranoia.o and link against newlib/libc.a, which
1156        for all the supported targets would be available in
1157        /usr/cygnus/progressive/H-host/target/lib/libc.a).
1158     3) make the change to reloc.c
1159     4) rebuild the linker
1160     5) repeat step 2
1161     6) if the resulting object files are the same, you have at least
1162        made it no worse
1163     7) if they are different you have to figure out which version is
1164        right.  */

1632         The insides of a reloc code.  The idea is that, eventually, there

2009   The Alpha LITERAL/LITUSE relocs are produced by a symbol reference;
2010      the assembler turns it into a LDQ instruction to load the address of
2011      the symbol, and then fills in a register in the real instruction.
2012
2013      The LITERAL reloc, at the LDQ instruction, refers to the .lita
2014      section symbol.  The addend is ignored when writing, but is filled
2015      in with the file's GP value on reading, for convenience, as with the
2016      GPDISP_LO16 reloc.
2017
2018      The ELF_LITERAL reloc is somewhere between 16_GOTOFF and GPDISP_LO16.
2019      It should refer to the symbol to be referenced, as with 16_GOTOFF,
2020      but it generates output not based on the position within the .got
2021      section, but relative to the GP value chosen for the file during the
2022      final link stage.
2023
2024      The LITUSE reloc, on the instruction using the loaded address, gives
2025      information to the linker that it might be able to use to optimize
2026      away some literal section references.  The symbol is ignored (read
2027      as the absolute section symbol), and the "addend" indicates the type
2028      of instruction using the register:
2029               1 - "memory" fmt insn
2030               2 - byte-manipulation (byte offset reg)

2148   MIPS16 high 16 bits of 32-bit value but the low 16 bits will be sign
2149      extended and added to form the final result.  If the low 16
2150      bits form a negative number, we need to add one to the high value
2151      to compensate for the borrow when the low bits are added.

4195   These two relocations are used by the linker to determine which of
4196   the entries in a C++ virtual function table are actually used.  When
4197   the --gc-sections option is given, the linker will zero out the entries
4198   that are not used, so that the code for those functions need not be
4199   included in the output.
4200
4201   VTABLE_INHERIT is a zero-space relocation used to describe to the
4202   linker the inheritance tree of a C++ virtual function table.  The
4203   relocation's symbol should be the parent class' vtable, and the
4204   relocation should be located at the child vtable.
4205
4206   VTABLE_ENTRY is a zero-space relocation that describes the use of a
4207   virtual function table entry.  The reloc's symbol should refer to the
4208   table of the class mentioned in the code.  Off of that base, an offset
4209   describes the entry that is being used.  For Rela hosts, this offset
4210   is stored in the reloc's addend.  For Rel hosts, we are forced to put
4211   this offset in the reloc's section offset.
