        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.

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

227

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.

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}.

         the location.
659
 
660
         If pcrel_offset is set, we must further subtract the position
661
         of the location within the section.  Some targets arrange for
662
         the addend to be the negative of the position of the location
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.

         that this reloc will be correctly computed when the final

671
         up with the negative of the location within the section,
672
         which means we must adjust the existing addend by the change
673
         in the location within the section.  If pcrel_offset is TRUE
674
         we do not want to adjust the existing addend at all.

         producing relocatable output it is not what the code

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

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.

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

DESCRIPTION
1633
        The insides of a reloc code.  The idea is that, eventually, there
1634
        will be one enumerator for every type of relocation we ever do.
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.

  These PC-relative relocations are stored as word displacements --
1802
i.e., byte displacements shifted right two bits.  The 30-bit word
1803
displacement (<<32_PCREL_S2>> -- 32 bits, shifted 2) is used on the
1804
SPARC.  (SPARC tools generally refer to this as <<WDISP30>>.)  The
1805 225 jeremybenn
signed 16-bit displacement is used on the MIPS, the 23-bit
1806
displacement is used on the Alpha and the 28-bit displacement is used

  BFD_RELOC_ALPHA_GPDISP_HI16
2030
ENUMDOC
2031
  Alpha ECOFF and ELF relocations.  Some of these treat the symbol or
2032
     "addend" in some special way.
2033
  For GPDISP_HI16 ("gpdisp") relocations, the symbol is ignored when
2034
     writing; when reading, it will be the absolute section symbol.  The
2035
     addend is the displacement in bytes of the "lda" instruction from
2036
     the "ldah" instruction (which is at the address of this reloc).
2037
ENUM
2038
  BFD_RELOC_ALPHA_GPDISP_LO16
2039
ENUMDOC
2040
  For GPDISP_LO16 ("ignore") relocations, the symbol is handled as
2041
     with GPDISP_HI16 relocs.  The addend is ignored when writing the
2042
     relocations out, and is filled in with the file's GP value on
2043
     reading, for convenience.
2044
 
2045
ENUM
2046
  BFD_RELOC_ALPHA_GPDISP
2047
ENUMDOC
2048
  The ELF GPDISP relocation is exactly the same as the GPDISP_HI16
2049
     relocation except that there is no accompanying GPDISP_LO16
2050
     relocation.

ENUMX
2057
  BFD_RELOC_ALPHA_LITUSE
2058
ENUMDOC
2059
  The Alpha LITERAL/LITUSE relocs are produced by a symbol reference;
2060
     the assembler turns it into a LDQ instruction to load the address of
2061
     the symbol, and then fills in a register in the real instruction.
2062
 
2063
     The LITERAL reloc, at the LDQ instruction, refers to the .lita
2064
     section symbol.  The addend is ignored when writing, but is filled
2065
     in with the file's GP value on reading, for convenience, as with the
2066
     GPDISP_LO16 reloc.
2067
 
2068
     The ELF_LITERAL reloc is somewhere between 16_GOTOFF and GPDISP_LO16.
2069
     It should refer to the symbol to be referenced, as with 16_GOTOFF,
2070
     but it generates output not based on the position within the .got
2071
     section, but relative to the GP value chosen for the file during the
2072
     final link stage.
2073
 
2074
     The LITUSE reloc, on the instruction using the loaded address, gives
2075
     information to the linker that it might be able to use to optimize
2076
     away some literal section references.  The symbol is ignored (read
2077
     as the absolute section symbol), and the "addend" indicates the type
2078
     of instruction using the register:
2079
              1 - "memory" fmt insn
2080
              2 - byte-manipulation (byte offset reg)
2081
              3 - jsr (target of branch)

  BFD_RELOC_ALPHA_HINT
2085
ENUMDOC
2086
  The HINT relocation indicates a value that should be filled into the
2087
     "hint" field of a jmp/jsr/ret instruction, for possible branch-
2088
     prediction logic which may be provided on some processors.

  These two relocations are used by the linker to determine which of
4317
  the entries in a C++ virtual function table are actually used.  When
4318
  the --gc-sections option is given, the linker will zero out the entries
4319
  that are not used, so that the code for those functions need not be
4320
  included in the output.
4321
 
4322
  VTABLE_INHERIT is a zero-space relocation used to describe to the
4323
  linker the inheritance tree of a C++ virtual function table.  The
4324
  relocation's symbol should be the parent class' vtable, and the
4325
  relocation should be located at the child vtable.
4326
 
4327
  VTABLE_ENTRY is a zero-space relocation that describes the use of a
4328
  virtual function table entry.  The reloc's symbol should refer to the
4329
  table of the class mentioned in the code.  Off of that base, an offset
4330
  describes the entry that is being used.  For Rela hosts, this offset
4331
  is stored in the reloc's addend.  For Rel hosts, we are forced to put
4332
  this offset in the reloc's section offset.
