22 /* Most of this hacked by Steve Chamberlain,
28 BFD supports a number of different flavours of coff format.
29 The major differences between formats are the sizes and
30 alignments of fields in structures on disk, and the occasional
33 Coff in all its varieties is implemented with a few common
34 files and a number of implementation specific files. For
35 example, The 88k bcs coff format is implemented in the file
36 @file{coff-m88k.c}. This file @code{#include}s
37 @file{coff/m88k.h} which defines the external structure of the
38 coff format for the 88k, and @file{coff/internal.h} which
39 defines the internal structure. @file{coff-m88k.c} also
40 defines the relocations used by the 88k format
43 The Intel i960 processor version of coff is implemented in
44 @file{coff-i960.c}. This file has the same structure as
45 @file{coff-m88k.c}, except that it includes @file{coff/i960.h}
46 rather than @file{coff-m88k.h}.
49 Porting to a new version of coff
51 The recommended method is to select from the existing
52 implementations the version of coff which is most like the one
53 you want to use. For example, we'll say that i386 coff is
54 the one you select, and that your coff flavour is called foo.
55 Copy @file{i386coff.c} to @file{foocoff.c}, copy
56 @file{../include/coff/i386.h} to @file{../include/coff/foo.h},
57 and add the lines to @file{targets.c} and @file{Makefile.in}
58 so that your new back end is used. Alter the shapes of the
59 structures in @file{../include/coff/foo.h} so that they match
60 what you need. You will probably also have to add
61 @code{#ifdef}s to the code in @file{coff/internal.h} and
62 @file{coffcode.h} if your version of coff is too wild.
64 You can verify that your new BFD backend works quite simply by
65 building @file{objdump} from the @file{binutils} directory,
66 and making sure that its version of what's going on and your
67 host system's idea (assuming it has the pretty standard coff
68 dump utility, usually called @code{att-dump} or just
69 @code{dump}) are the same. Then clean up your code, and send
70 what you've done to Cygnus. Then your stuff will be in the
71 next release, and you won't have to keep integrating it.
74 How the coff backend works
79 The Coff backend is split into generic routines that are
80 applicable to any Coff target and routines that are specific
81 to a particular target. The target-specific routines are
82 further split into ones which are basically the same for all
83 Coff targets except that they use the external symbol format
84 or use different values for certain constants.
86 The generic routines are in @file{coffgen.c}. These routines
87 work for any Coff target. They use some hooks into the target
88 specific code; the hooks are in a @code{bfd_coff_backend_data}
89 structure, one of which exists for each target.
91 The essentially similar target-specific routines are in
92 @file{coffcode.h}. This header file includes executable C code.
93 The various Coff targets first include the appropriate Coff
94 header file, make any special defines that are needed, and
95 then include @file{coffcode.h}.
97 Some of the Coff targets then also have additional routines in
98 the target source file itself.
100 For example, @file{coff-i960.c} includes
101 @file{coff/internal.h} and @file{coff/i960.h}. It then
102 defines a few constants, such as @code{I960}, and includes
103 @file{coffcode.h}. Since the i960 has complex relocation
104 types, @file{coff-i960.c} also includes some code to
105 manipulate the i960 relocs. This code is not in
106 @file{coffcode.h} because it would not be used by any other
110 Coff long section names
112 In the standard Coff object format, section names are limited to
113 the eight bytes available in the @code{s_name} field of the
114 @code{SCNHDR} section header structure. The format requires the
115 field to be NUL-padded, but not necessarily NUL-terminated, so
116 the longest section names permitted are a full eight characters.
118 The Microsoft PE variants of the Coff object file format add
119 an extension to support the use of long section names. This
120 extension is defined in section 4 of the Microsoft PE/COFF
121 specification (rev 8.1). If a section name is too long to fit
122 into the section header's @code{s_name} field, it is instead
123 placed into the string table, and the @code{s_name} field is
124 filled with a slash ("/") followed by the ASCII decimal
125 representation of the offset of the full name relative to the
128 Note that this implies that the extension can only be used in object
129 files, as executables do not contain a string table. The standard
130 specifies that long section names from objects emitted into executable
131 images are to be truncated.
133 However, as a GNU extension, BFD can generate executable images
134 that contain a string table and long section names. This
135 would appear to be technically valid, as the standard only says
136 that Coff debugging information is deprecated, not forbidden,
137 and in practice it works, although some tools that parse PE files
138 expecting the MS standard format may become confused; @file{PEview} is
141 The functionality is supported in BFD by code implemented under
142 the control of the macro @code{COFF_LONG_SECTION_NAMES}. If not
143 defined, the format does not support long section names in any way.
144 If defined, it is used to initialise a flag,
145 @code{_bfd_coff_long_section_names}, and a hook function pointer,
146 @code{_bfd_coff_set_long_section_names}, in the Coff backend data
147 structure. The flag controls the generation of long section names
148 in output BFDs at runtime; if it is false, as it will be by default
149 when generating an executable image, long section names are truncated;
150 if true, the long section names extension is employed. The hook
151 points to a function that allows the value of the flag to be altered
152 at runtime, on formats that support long section names at all; on
153 other formats it points to a stub that returns an error indication.
155 With input BFDs, the flag is set according to whether any long section
156 names are detected while reading the section headers. For a completely
157 new BFD, the flag is set to the default for the target format. This
158 information can be used by a client of the BFD library when deciding
159 what output format to generate, and means that a BFD that is opened
160 for read and subsequently converted to a writeable BFD and modified
161 in-place will retain whatever format it had on input.
163 If @code{COFF_LONG_SECTION_NAMES} is simply defined (blank), or is
164 defined to the value "1", then long section names are enabled by
165 default; if it is defined to the value zero, they are disabled by
166 default (but still accepted in input BFDs). The header @file{coffcode.h}
167 defines a macro, @code{COFF_DEFAULT_LONG_SECTION_NAMES}, which is
168 used in the backends to initialise the backend data structure fields
169 appropriately; see the comments for further detail.
174 Each flavour of coff supported in BFD has its own header file
175 describing the external layout of the structures. There is also
176 an internal description of the coff layout, in
177 @file{coff/internal.h}. A major function of the
178 coff backend is swapping the bytes and twiddling the bits to
179 translate the external form of the structures into the normal
180 internal form. This is all performed in the
181 @code{bfd_swap}_@i{thing}_@i{direction} routines. Some
182 elements are different sizes between different versions of
183 coff; it is the duty of the coff version specific include file
184 to override the definitions of various packing routines in
185 @file{coffcode.h}. E.g., the size of line number entry in coff is
186 sometimes 16 bits, and sometimes 32 bits. @code{#define}ing
187 @code{PUT_LNSZ_LNNO} and @code{GET_LNSZ_LNNO} will select the
188 correct one. No doubt, some day someone will find a version of
189 coff which has a varying field size not catered to at the
190 moment. To port BFD, that person will have to add more @code{#defines}.
191 Three of the bit twiddling routines are exported to
192 @code{gdb}; @code{coff_swap_aux_in}, @code{coff_swap_sym_in}
193 and @code{coff_swap_lineno_in}. @code{GDB} reads the symbol
194 table on its own, but uses BFD to fix things up. More of the
195 bit twiddlers are exported for @code{gas};
196 @code{coff_swap_aux_out}, @code{coff_swap_sym_out},
197 @code{coff_swap_lineno_out}, @code{coff_swap_reloc_out},
198 @code{coff_swap_filehdr_out}, @code{coff_swap_aouthdr_out},
199 @code{coff_swap_scnhdr_out}. @code{Gas} currently keeps track
200 of all the symbol table and reloc drudgery itself, thereby
201 saving the internal BFD overhead, but uses BFD to swap things
202 on the way out, making cross ports much safer. Doing so also
203 allows BFD (and thus the linker) to use the same header files
204 as @code{gas}, which makes one avenue to disaster disappear.
209 The simple canonical form for symbols used by BFD is not rich
210 enough to keep all the information available in a coff symbol
211 table. The back end gets around this problem by keeping the original
212 symbol table around, "behind the scenes".
214 When a symbol table is requested (through a call to
215 @code{bfd_canonicalize_symtab}), a request gets through to
216 @code{coff_get_normalized_symtab}. This reads the symbol table from
217 the coff file and swaps all the structures inside into the
218 internal form. It also fixes up all the pointers in the table
219 (represented in the file by offsets from the first symbol in
220 the table) into physical pointers to elements in the new
221 internal table. This involves some work since the meanings of
222 fields change depending upon context: a field that is a
223 pointer to another structure in the symbol table at one moment
224 may be the size in bytes of a structure at the next. Another
225 pass is made over the table. All symbols which mark file names
226 (<<C_FILE>> symbols) are modified so that the internal
227 string points to the value in the auxent (the real filename)
228 rather than the normal text associated with the symbol
231 At this time the symbol names are moved around. Coff stores
232 all symbols less than nine characters long physically
233 within the symbol table; longer strings are kept at the end of
234 the file in the string table. This pass moves all strings
235 into memory and replaces them with pointers to the strings.
237 The symbol table is massaged once again, this time to create
238 the canonical table used by the BFD application. Each symbol
239 is inspected in turn, and a decision made (using the
240 @code{sclass} field) about the various flags to set in the
241 @code{asymbol}. @xref{Symbols}. The generated canonical table
242 shares strings with the hidden internal symbol table.
244 Any linenumbers are read from the coff file too, and attached
245 to the symbols which own the functions the linenumbers belong to.
250 Writing a symbol to a coff file which didn't come from a coff
251 file will lose any debugging information. The @code{asymbol}
252 structure remembers the BFD from which the symbol was taken, and on
253 output the back end makes sure that the same destination target as
254 source target is present.
256 When the symbols have come from a coff file then all the
257 debugging information is preserved.
259 Symbol tables are provided for writing to the back end in a
260 vector of pointers to pointers. This allows applications like
261 the linker to accumulate and output large symbol tables
262 without having to do too much byte copying.
264 This function runs through the provided symbol table and
265 patches each symbol marked as a file place holder
266 (@code{C_FILE}) to point to the next file place holder in the
267 list. It also marks each @code{offset} field in the list with
268 the offset from the first symbol of the current symbol.
270 Another function of this procedure is to turn the canonical
271 value form of BFD into the form used by coff. Internally, BFD
272 expects symbol values to be offsets from a section base; so a
273 symbol physically at 0x120, but in a section starting at
274 0x100, would have the value 0x20. Coff expects symbols to
275 contain their final value, so symbols have their values
276 changed at this point to reflect their sum with their owning
277 section. This transformation uses the
278 <<output_section>> field of the @code{asymbol}'s
279 @code{asection} @xref{Sections}.
281 o <<coff_mangle_symbols>>
283 This routine runs though the provided symbol table and uses
284 the offsets generated by the previous pass and the pointers
285 generated when the symbol table was read in to create the
286 structured hierarchy required by coff. It changes each pointer
287 to a symbol into the index into the symbol table of the asymbol.
289 o <<coff_write_symbols>>
291 This routine runs through the symbol table and patches up the
292 symbols from their internal form into the coff way, calls the
293 bit twiddlers, and writes out the table to the file.
302 The hidden information for an <<asymbol>> is described in a
303 <<combined_entry_type>>:
307 .typedef struct coff_ptr_struct
309 . {* Remembers the offset from the first symbol in the file for
310 . this symbol. Generated by coff_renumber_symbols. *}

5133 Coff relocations are easily transformed into the internal BFD form
5136 Reading a coff relocation table is done in the following stages:
5138 o Read the entire coff relocation table into memory.
5140 o Process each relocation in turn; first swap it from the
5141 external to the internal form.
5143 o Turn the symbol referenced in the relocation's symbol index
5144 into a pointer into the canonical symbol table.
5145 This table is the same as the one returned by a call to
5146 @code{bfd_canonicalize_symtab}. The back end will call that
5147 routine and save the result if a canonicalization hasn't been done.
5149 o The reloc index is turned into a pointer to a howto
5150 structure, in a back end specific way. For instance, the 386
5151 and 960 use the @code{r_type} to directly produce an index
5152 into a howto table vector; the 88k subtracts a number from the
5153 @code{r_type} field and creates an addend field.
