        coff backends

30
        BFD supports a number of different flavours of coff format.
31
        The major differences between formats are the sizes and
32
        alignments of fields in structures on disk, and the occasional
33
        extra field.
34
 
35
        Coff in all its varieties is implemented with a few common
36
        files and a number of implementation specific files. For
37
        example, The 88k bcs coff format is implemented in the file
38
        @file{coff-m88k.c}. This file @code{#include}s
39
        @file{coff/m88k.h} which defines the external structure of the
40
        coff format for the 88k, and @file{coff/internal.h} which
41
        defines the internal structure. @file{coff-m88k.c} also
42
        defines the relocations used by the 88k format
43
        @xref{Relocations}.
44
 
45
        The Intel i960 processor version of coff is implemented in
46
        @file{coff-i960.c}. This file has the same structure as
47
        @file{coff-m88k.c}, except that it includes @file{coff/i960.h}
48
        rather than @file{coff-m88k.h}.

        Porting to a new version of coff
52
 
53
        The recommended method is to select from the existing
54
        implementations the version of coff which is most like the one
55
        you want to use.  For example, we'll say that i386 coff is
56
        the one you select, and that your coff flavour is called foo.
57
        Copy @file{i386coff.c} to @file{foocoff.c}, copy
58
        @file{../include/coff/i386.h} to @file{../include/coff/foo.h},
59
        and add the lines to @file{targets.c} and @file{Makefile.in}
60
        so that your new back end is used. Alter the shapes of the
61
        structures in @file{../include/coff/foo.h} so that they match
62
        what you need. You will probably also have to add
63
        @code{#ifdef}s to the code in @file{coff/internal.h} and
64
        @file{coffcode.h} if your version of coff is too wild.
65
 
66
        You can verify that your new BFD backend works quite simply by
67
        building @file{objdump} from the @file{binutils} directory,
68
        and making sure that its version of what's going on and your
69
        host system's idea (assuming it has the pretty standard coff
70
        dump utility, usually called @code{att-dump} or just
71
        @code{dump}) are the same.  Then clean up your code, and send
72
        what you've done to Cygnus. Then your stuff will be in the
73
        next release, and you won't have to keep integrating it.

        How the coff backend works
77
 
78
SUBSUBSECTION
79
        File layout
80
 
81
        The Coff backend is split into generic routines that are
82
        applicable to any Coff target and routines that are specific
83
        to a particular target.  The target-specific routines are
84
        further split into ones which are basically the same for all
85
        Coff targets except that they use the external symbol format
86
        or use different values for certain constants.
87
 
88
        The generic routines are in @file{coffgen.c}.  These routines
89
        work for any Coff target.  They use some hooks into the target
90
        specific code; the hooks are in a @code{bfd_coff_backend_data}
91
        structure, one of which exists for each target.
92
 
93
        The essentially similar target-specific routines are in
94
        @file{coffcode.h}.  This header file includes executable C code.
95
        The various Coff targets first include the appropriate Coff
96
        header file, make any special defines that are needed, and
97
        then include @file{coffcode.h}.
98
 
99
        Some of the Coff targets then also have additional routines in
100
        the target source file itself.
101
 
102
        For example, @file{coff-i960.c} includes
103
        @file{coff/internal.h} and @file{coff/i960.h}.  It then
104
        defines a few constants, such as @code{I960}, and includes
105
        @file{coffcode.h}.  Since the i960 has complex relocation
106
        types, @file{coff-i960.c} also includes some code to
107
        manipulate the i960 relocs.  This code is not in
108
        @file{coffcode.h} because it would not be used by any other
109
        target.

        Coff long section names
113
 
114
        In the standard Coff object format, section names are limited to
115
        the eight bytes available in the @code{s_name} field of the
116
        @code{SCNHDR} section header structure.  The format requires the
117
        field to be NUL-padded, but not necessarily NUL-terminated, so
118
        the longest section names permitted are a full eight characters.
119
 
120
        The Microsoft PE variants of the Coff object file format add
121
        an extension to support the use of long section names.  This
122
        extension is defined in section 4 of the Microsoft PE/COFF
123
        specification (rev 8.1).  If a section name is too long to fit
124
        into the section header's @code{s_name} field, it is instead
125
        placed into the string table, and the @code{s_name} field is
126
        filled with a slash ("/") followed by the ASCII decimal
127
        representation of the offset of the full name relative to the
128
        string table base.
129
 
130
        Note that this implies that the extension can only be used in object
131
        files, as executables do not contain a string table.  The standard
132
        specifies that long section names from objects emitted into executable
133
        images are to be truncated.
134
 
135
        However, as a GNU extension, BFD can generate executable images
136
        that contain a string table and long section names.  This
137
        would appear to be technically valid, as the standard only says
138
        that Coff debugging information is deprecated, not forbidden,
139
        and in practice it works, although some tools that parse PE files
140
        expecting the MS standard format may become confused; @file{PEview} is
141
        one known example.
142
 
143
        The functionality is supported in BFD by code implemented under
144
        the control of the macro @code{COFF_LONG_SECTION_NAMES}.  If not
145
        defined, the format does not support long section names in any way.
146
        If defined, it is used to initialise a flag,
147
        @code{_bfd_coff_long_section_names}, and a hook function pointer,
148
        @code{_bfd_coff_set_long_section_names}, in the Coff backend data
149
        structure.  The flag controls the generation of long section names
150
        in output BFDs at runtime; if it is false, as it will be by default
151
        when generating an executable image, long section names are truncated;
152
        if true, the long section names extension is employed.  The hook
153
        points to a function that allows the value of the flag to be altered
154
        at runtime, on formats that support long section names at all; on
155
        other formats it points to a stub that returns an error indication.
156
 
157
        With input BFDs, the flag is set according to whether any long section
158
        names are detected while reading the section headers.  For a completely
159
        new BFD, the flag is set to the default for the target format.  This
160
        information can be used by a client of the BFD library when deciding
161
        what output format to generate, and means that a BFD that is opened
162
        for read and subsequently converted to a writeable BFD and modified
163
        in-place will retain whatever format it had on input.
164
 
165
        If @code{COFF_LONG_SECTION_NAMES} is simply defined (blank), or is
166
        defined to the value "1", then long section names are enabled by
167
        default; if it is defined to the value zero, they are disabled by
168
        default (but still accepted in input BFDs).  The header @file{coffcode.h}
169
        defines a macro, @code{COFF_DEFAULT_LONG_SECTION_NAMES}, which is
170
        used in the backends to initialise the backend data structure fields
171
        appropriately; see the comments for further detail.

        Bit twiddling
175
 
176
        Each flavour of coff supported in BFD has its own header file
177
        describing the external layout of the structures. There is also
178
        an internal description of the coff layout, in
179
        @file{coff/internal.h}. A major function of the
180
        coff backend is swapping the bytes and twiddling the bits to
181
        translate the external form of the structures into the normal
182
        internal form. This is all performed in the
183
        @code{bfd_swap}_@i{thing}_@i{direction} routines. Some
184
        elements are different sizes between different versions of
185
        coff; it is the duty of the coff version specific include file
186
        to override the definitions of various packing routines in
187
        @file{coffcode.h}. E.g., the size of line number entry in coff is
188
        sometimes 16 bits, and sometimes 32 bits. @code{#define}ing
189
        @code{PUT_LNSZ_LNNO} and @code{GET_LNSZ_LNNO} will select the
190
        correct one. No doubt, some day someone will find a version of
191
        coff which has a varying field size not catered to at the
192
        moment. To port BFD, that person will have to add more @code{#defines}.
193
        Three of the bit twiddling routines are exported to
194
        @code{gdb}; @code{coff_swap_aux_in}, @code{coff_swap_sym_in}
195
        and @code{coff_swap_lineno_in}. @code{GDB} reads the symbol
196
        table on its own, but uses BFD to fix things up.  More of the
197
        bit twiddlers are exported for @code{gas};
198
        @code{coff_swap_aux_out}, @code{coff_swap_sym_out},
199
        @code{coff_swap_lineno_out}, @code{coff_swap_reloc_out},
200
        @code{coff_swap_filehdr_out}, @code{coff_swap_aouthdr_out},
201
        @code{coff_swap_scnhdr_out}. @code{Gas} currently keeps track
202
        of all the symbol table and reloc drudgery itself, thereby
203
        saving the internal BFD overhead, but uses BFD to swap things
204
        on the way out, making cross ports much safer.  Doing so also
205
        allows BFD (and thus the linker) to use the same header files
206
        as @code{gas}, which makes one avenue to disaster disappear.
207
 
208
SUBSUBSECTION
209
        Symbol reading
210
 
211
        The simple canonical form for symbols used by BFD is not rich
212
        enough to keep all the information available in a coff symbol
213
        table. The back end gets around this problem by keeping the original
214
        symbol table around, "behind the scenes".
215
 
216
        When a symbol table is requested (through a call to
217
        @code{bfd_canonicalize_symtab}), a request gets through to
218
        @code{coff_get_normalized_symtab}. This reads the symbol table from
219
        the coff file and swaps all the structures inside into the
220
        internal form. It also fixes up all the pointers in the table
221
        (represented in the file by offsets from the first symbol in
222
        the table) into physical pointers to elements in the new
223
        internal table. This involves some work since the meanings of
224
        fields change depending upon context: a field that is a
225
        pointer to another structure in the symbol table at one moment
226
        may be the size in bytes of a structure at the next.  Another
227
        pass is made over the table. All symbols which mark file names
228
        (<<C_FILE>> symbols) are modified so that the internal
229
        string points to the value in the auxent (the real filename)
230
        rather than the normal text associated with the symbol
231
        (@code{".file"}).
232
 
233
        At this time the symbol names are moved around. Coff stores
234
        all symbols less than nine characters long physically
235
        within the symbol table; longer strings are kept at the end of
236 225 jeremybenn
        the file in the string table. This pass moves all strings
237 24 jeremybenn
        into memory and replaces them with pointers to the strings.
238
 
239
        The symbol table is massaged once again, this time to create
240
        the canonical table used by the BFD application. Each symbol
241
        is inspected in turn, and a decision made (using the
242
        @code{sclass} field) about the various flags to set in the
243
        @code{asymbol}.  @xref{Symbols}. The generated canonical table
244
        shares strings with the hidden internal symbol table.
245
 
246
        Any linenumbers are read from the coff file too, and attached
247
        to the symbols which own the functions the linenumbers belong to.
248
 
249
SUBSUBSECTION
250
        Symbol writing
251
 
252
        Writing a symbol to a coff file which didn't come from a coff
253
        file will lose any debugging information. The @code{asymbol}
254
        structure remembers the BFD from which the symbol was taken, and on
255
        output the back end makes sure that the same destination target as
256
        source target is present.
257
 
258
        When the symbols have come from a coff file then all the
259
        debugging information is preserved.
260
 
261
        Symbol tables are provided for writing to the back end in a
262
        vector of pointers to pointers. This allows applications like
263
        the linker to accumulate and output large symbol tables
264
        without having to do too much byte copying.
265
 
266
        This function runs through the provided symbol table and
267
        patches each symbol marked as a file place holder
268
        (@code{C_FILE}) to point to the next file place holder in the
269
        list. It also marks each @code{offset} field in the list with
270
        the offset from the first symbol of the current symbol.
271
 
272
        Another function of this procedure is to turn the canonical
273
        value form of BFD into the form used by coff. Internally, BFD
274
        expects symbol values to be offsets from a section base; so a
275
        symbol physically at 0x120, but in a section starting at
276
        0x100, would have the value 0x20. Coff expects symbols to
277
        contain their final value, so symbols have their values
278
        changed at this point to reflect their sum with their owning
279
        section.  This transformation uses the
280
        <<output_section>> field of the @code{asymbol}'s
281
        @code{asection} @xref{Sections}.
282
 
283
        o <<coff_mangle_symbols>>
284
 
285
        This routine runs though the provided symbol table and uses
286
        the offsets generated by the previous pass and the pointers
287
        generated when the symbol table was read in to create the
288
        structured hierarchy required by coff. It changes each pointer
289
        to a symbol into the index into the symbol table of the asymbol.
290
 
291
        o <<coff_write_symbols>>
292
 
293
        This routine runs through the symbol table and patches up the
294
        symbols from their internal form into the coff way, calls the
295
        bit twiddlers, and writes out the table to the file.

898
             symbol" (section name).  The second is the comdat
899
             symbol name.  Here, we've found the first

911
 
912
             If the section name is simply a section name (no
913
             $) we presume it's MS-generated, and look at
914
             precisely the second symbol for the comdat name.
915
             If the section name has a $, we assume it's
916
             gas-generated, and look for <something> (whatever
917
             follows the $) as the comdat symbol.  */

934
                   appears that the second entry serves BOTH
935
                   as the comdat symbol and the defining
936
                   symbol record (either C_STAT or C_EXT,

941
                   adjacent, but on Alpha, they have been

                   found separated.)

1104
   look at the symbol table anyway, we return the symbol table index

   ugly, but there's really nowhere else that we have access to the

1108

        Reading linenumbers
4416
 
4417
        Creating the linenumber table is done by reading in the entire
4418
        coff linenumber table, and creating another table for internal use.
4419
 
4420
        A coff linenumber table is structured so that each function
4421
        is marked as having a line number of 0. Each line within the
4422
        function is an offset from the first line in the function. The
4423
        base of the line number information for the table is stored in
4424
        the symbol associated with the function.
4425
 
4426
        Note: The PE format uses line number 0 for a flag indicating a
4427
        new source file.
4428
 
4429

5056
        o Process each relocation in turn; first swap it from the

        into a pointer into the canonical symbol table.
5061
        This table is the same as the one returned by a call to

5065
        o The reloc index is turned into a pointer to a howto
5066
        structure, in a back end specific way. For instance, the 386
5067
        and 960 use the @code{r_type} to directly produce an index
5068
        into a howto table vector; the 88k subtracts a number from the
5069
        @code{r_type} field and creates an addend field.
