28 coff backends
29
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}.
49
50SUBSECTION
51 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.

76 How the coff backend works
77
78SUBSUBSECTION
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.

111SUBSUBSECTION
112 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.
0408dee6
DK
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.
88183869
DK
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.

173SUBSUBSECTION
174 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}
00692651 195 and @code{coff_swap_lineno_in}. @code{GDB} reads the symbol
252b5132
RH
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
208SUBSUBSECTION
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
46f2f11d 236 the file in the string table. This pass moves all strings
252b5132
RH
237 into memory and replaces them with pointers to the strings.
238
252b5132
RH
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
249SUBSUBSECTION
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
ed781d5d 288 structured hierarchy required by coff. It changes each pointer
252b5132
RH
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.

4338 I have found no documentation on the contents of this section.
4339 Experimentation indicates that the section contains zero or more
4340 records, each of which has the following structure:
4341
4342 - a (four byte) word holding the length of this record, in words,
4343 - a word that always seems to be set to "2",
4344 - the path to a shared library, null-terminated and then padded
4345 to a whole word boundary.
4346
4347 bfd_assert calls have been added to alert if an attempt is made
4348 to write a section which doesn't follow these assumptions. The

5030 Reading relocations
5031
5032 Coff relocations are easily transformed into the internal BFD form
5033 (@code{arelent}).
5034
5035 Reading a coff relocation table is done in the following stages:
5036
5037 o Read the entire coff relocation table into memory.
5038
5039 o Process each relocation in turn; first swap it from the
5040 external to the internal form.
5041
5042 o Turn the symbol referenced in the relocation's symbol index
5043 into a pointer into the canonical symbol table.
5044 This table is the same as the one returned by a call to
5045 @code{bfd_canonicalize_symtab}. The back end will call that
5046 routine and save the result if a canonicalization hasn't been done.
5047
5048 o The reloc index is turned into a pointer to a howto
5049 structure, in a back end specific way. For instance, the 386
5050 and 960 use the @code{r_type} to directly produce an index
5051 into a howto table vector; the 88k subtracts a number from the
5052 @code{r_type} field and creates an addend field.
