  26         Relocations
  27
  28         BFD maintains relocations in much the same way it maintains
  29         symbols: they are left alone until required, then read in
  30         en-masse and translated into an internal form.  A common
  31         routine <<bfd_perform_relocation>> acts upon the
  32         canonical form to do the fixup.
  33
  34         Relocations are maintained on a per section basis,
  35         while symbols are maintained on a per BFD basis.
  36
  37         All that a back end has to do to fit the BFD interface is to create
  38         a <<struct reloc_cache_entry>> for each relocation
  39         in a particular section, and fill in the right bits of the structures.

 119 DESCRIPTION
 120
 121         Here is a description of each of the fields within an <<arelent>>:
 122
 123         o <<sym_ptr_ptr>>
 124
 125         The symbol table pointer points to a pointer to the symbol
 126         associated with the relocation request.  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.

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

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

 663          within the section; for example, i386-aout does this.  For
 664          i386-aout, pcrel_offset is FALSE.  Some other targets do not
 665          include the position of the location; for example, m88kbcs,
 666          or ELF.  For those targets, pcrel_offset is TRUE.

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

 950           (bfd *abfd,

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

1042
1043          We start by subtracting the address of the section containing
1044          the location.
1045
1046          If pcrel_offset is set, we must further subtract the position
1047          of the location within the section.  Some targets arrange for
1048          the addend to be the negative of the position of the location
1049          within the section; for example, i386-aout does this.  For
1050          i386-aout, pcrel_offset is FALSE.  Some other targets do not
1051          include the position of the location; for example, m88kbcs,
1052          or ELF.  For those targets, pcrel_offset is TRUE.
1053
1054          If we are producing relocatable output, then we must ensure
1055          that this reloc will be correctly computed when the final
1056          relocation is done.  If pcrel_offset is FALSE we want to wind
1057          up with the negative of the location within the section,
1058          which means we must adjust the existing addend by the change
1059          in the location within the section.  If pcrel_offset is TRUE
1060          we do not want to adjust the existing addend at all.

1063          producing relocatable output it is not what the code

1101
1102 However, Ian wrote the following, regarding removing the line below,
1103 which explains why it is still enabled:  --djm
1104
1105 If you put a patch like that into BFD you need to check all the COFF
1106 linkers.  I am fairly certain that patch will break coff-i386 (e.g.,
1107 SCO); see coff_i386_reloc in coff-i386.c where I worked around the
1108 problem in a different way.  There may very well be a reason that the
1109 code works as it does.
1110
1111 Hmmm.  The first obvious point is that bfd_install_relocation should
1112 not have any tests that depend upon the flavour.  It's seem like
1113 entirely the wrong place for such a thing.  The second obvious point
1114 is that the current code ignores the reloc addend when producing
1115 relocatable output for COFF.  That's peculiar.  In fact, I really
1116 have no idea what the point of the line you want to remove is.
1117
1118 A typical COFF reloc subtracts the old value of the symbol and adds in
1119 the new value to the location in the object file (if it's a pc
1120 relative reloc it adds the difference between the symbol value and the
1121 location).  When relocating we need to preserve that property.
1122
1123 BFD handles this by setting the addend to the negative of the old
1124 value of the symbol.  Unfortunately it handles common symbols in a
1125 non-standard way (it doesn't subtract the old value) but that's a
1126 different story (we can't change it without losing backward
1127 compatibility with old object files) (coff-i386 does subtract the old
1128 value, to be compatible with existing coff-i386 targets, like SCO).
1129
1130 So everything works fine when not producing relocatable output.  When
1131 we are producing relocatable output, logically we should do exactly
1132 what we do when not producing relocatable output.  Therefore, your
1133 patch is correct.  In fact, it should probably always just set
1134 reloc_entry->addend to 0 for all cases, since it is, in fact, going to
1135 add the value into the object file.  This won't hurt the COFF code,
1136 which doesn't use the addend; I'm not sure what it will do to other
1137 formats (the thing to check for would be whether any formats both use
1138 the addend and set partial_inplace).
1139
1140 When I wanted to make coff-i386 produce relocatable output, I ran
1141 into the problem that you are running into: I wanted to remove that
1142 line.  Rather than risk it, I made the coff-i386 relocs use a special
1143 function; it's coff_i386_reloc in coff-i386.c.  The function
1144 specifically adds the addend field into the object file, knowing that
1145 bfd_install_relocation is not going to.  If you remove that line, then
1146 coff-i386.c will wind up adding the addend field in twice.  It's
1147 trivial to fix; it just needs to be done.
1148
1149 The problem with removing the line is just that it may break some
1150 working code.  With BFD it's hard to be sure of anything.  The right
1151 way to deal with this is simply to build and test at least all the
1152 supported COFF targets.  It should be straightforward if time and disk
1153 space consuming.  For each target:
1154     1) build the linker
1155     2) generate some executable, and link it using -r (I would
1156        probably use paranoia.o and link against newlib/libc.a, which
1157        for all the supported targets would be available in
1158        /usr/cygnus/progressive/H-host/target/lib/libc.a).
1159     3) make the change to reloc.c
1160     4) rebuild the linker
1161     5) repeat step 2
1162     6) if the resulting object files are the same, you have at least
1163        made it no worse
1164     7) if they are different you have to figure out which version is
1165        right.  */

1635         Pass one of these values to <<bfd_reloc_type_lookup>>, and it'll
1636         return a howto pointer.
1637
1638         This does mean that the application must determine the correct
1639         enumerator value; you can't get a howto pointer from a random set
1640         of attributes.

2034 ENUMDOC
2035   The Alpha LITERAL/LITUSE relocs are produced by a symbol reference;
2036      the assembler turns it into a LDQ instruction to load the address of
2037      the symbol, and then fills in a register in the real instruction.
2038
2039      The LITERAL reloc, at the LDQ instruction, refers to the .lita
2040      section symbol.  The addend is ignored when writing, but is filled
2041      in with the file's GP value on reading, for convenience, as with the
2042      GPDISP_LO16 reloc.
2043
2044      The ELF_LITERAL reloc is somewhere between 16_GOTOFF and GPDISP_LO16.
2045      It should refer to the symbol to be referenced, as with 16_GOTOFF,
2046      but it generates output not based on the position within the .got
2047      section, but relative to the GP value chosen for the file during the
2048      final link stage.
2049
2050      The LITUSE reloc, on the instruction using the loaded address, gives
2051      information to the linker that it might be able to use to optimize
2052      away some literal section references.  The symbol is ignored (read
2053      as the absolute section symbol), and the "addend" indicates the type
2054      of instruction using the register:
2055               1 - "memory" fmt insn
2056               2 - byte-manipulation (byte offset reg)

4245   These two relocations are used by the linker to determine which of
4246   the entries in a C++ virtual function table are actually used.  When
4247   the --gc-sections option is given, the linker will zero out the entries
4248   that are not used, so that the code for those functions need not be
4249   included in the output.
4250
4251   VTABLE_INHERIT is a zero-space relocation used to describe to the
4252   linker the inheritance tree of a C++ virtual function table.  The
4253   relocation's symbol should be the parent class' vtable, and the
4254   relocation should be located at the child vtable.
4255
4256   VTABLE_ENTRY is a zero-space relocation that describes the use of a
4257   virtual function table entry.  The reloc's symbol should refer to the
4258   table of the class mentioned in the code.  Off of that base, an offset
4259   describes the entry that is being used.  For Rela hosts, this offset
4260   is stored in the reloc's addend.  For Rel hosts, we are forced to put
4261   this offset in the reloc's section offset.
