50 BFD is a package which allows applications to use the same routines to
51 operate on object files whatever the object file format. A new object
52 file format can be supported simply by creating a new BFD back end and
53 adding it to the library.
55 BFD is split into two parts: the front end, and the back ends (one
56 for each object file format).
57 * The front end of BFD provides the interface to the user. It manages
58 memory and various canonical data structures. The front end also
59 decides which back end to use and when to call back end routines.
61 * The back ends provide BFD its view of the real world. Each back
62 end provides a set of calls which the BFD front end can use to
63 maintain its canonical form. The back ends also may keep around
64 information for their own use, for greater efficiency.

73 File: bfd.info, Node: History, Next: How It Works, Prev: Overview, Up: Overview
78 One spur behind BFD was the desire, on the part of the GNU 960 team at
79 Intel Oregon, for interoperability of applications on their COFF and
80 b.out file formats. Cygnus was providing GNU support for the team, and
81 was contracted to provide the required functionality.
83 The name came from a conversation David Wallace was having with
84 Richard Stallman about the library: RMS said that it would be quite
85 hard--David said "BFD". Stallman was right, but the name stuck.
87 At the same time, Ready Systems wanted much the same thing, but for
88 different object file formats: IEEE-695, Oasys, Srecords, a.out and 68k
91 BFD was first implemented by members of Cygnus Support; Steve
92 Chamberlain (`sac@cygnus.com'), John Gilmore (`gnu@cygnus.com'), K.
93 Richard Pixley (`rich@cygnus.com') and David Henkel-Wallace
97 File: bfd.info, Node: How It Works, Next: What BFD Version 2 Can Do, Prev: History, Up: Overview
102 To use the library, include `bfd.h' and link with `libbfd.a'.
104 BFD provides a common interface to the parts of an object file for a
107 When an application successfully opens a target file (object,
108 archive, or whatever), a pointer to an internal structure is returned.
109 This pointer points to a structure called `bfd', described in `bfd.h'.
110 Our convention is to call this pointer a BFD, and instances of it
111 within code `abfd'. All operations on the target object file are
112 applied as methods to the BFD. The mapping is defined within `bfd.h'
113 in a set of macros, all beginning with `bfd_' to reduce namespace
116 For example, this sequence does what you would probably expect:
117 return the number of sections in an object file attached to a BFD
122 unsigned int number_of_sections (abfd)
125 return bfd_count_sections (abfd);
128 The abstraction used within BFD is that an object file has:
132 * a number of sections containing raw data (*note Sections::),
134 * a set of relocations (*note Relocations::), and
136 * some symbol information (*note Symbols::).
137 Also, BFDs opened for archives have the additional attribute of an
138 index and contain subordinate BFDs. This approach is fine for a.out and
139 coff, but loses efficiency when applied to formats such as S-records and
143 File: bfd.info, Node: What BFD Version 2 Can Do, Prev: How It Works, Up: Overview
145 1.3 What BFD Version 2 Can Do
146 =============================
148 When an object file is opened, BFD subroutines automatically determine
149 the format of the input object file. They then build a descriptor in
150 memory with pointers to routines that will be used to access elements of
151 the object file's data structures.
153 As different information from the object files is required, BFD
154 reads from different sections of the file and processes them. For
155 example, a very common operation for the linker is processing symbol
156 tables. Each BFD back end provides a routine for converting between
157 the object file's representation of symbols and an internal canonical
158 format. When the linker asks for the symbol table of an object file, it
159 calls through a memory pointer to the routine from the relevant BFD
160 back end which reads and converts the table into a canonical form. The
161 linker then operates upon the canonical form. When the link is finished
162 and the linker writes the output file's symbol table, another BFD back
163 end routine is called to take the newly created symbol table and
164 convert it into the chosen output format.

169 * Canonical format:: The BFD canonical object-file format
172 File: bfd.info, Node: BFD information loss, Next: Canonical format, Up: What BFD Version 2 Can Do
174 1.3.1 Information Loss
175 ----------------------
177 _Information can be lost during output._ The output formats supported
178 by BFD do not provide identical facilities, and information which can
179 be described in one form has nowhere to go in another format. One
180 example of this is alignment information in `b.out'. There is nowhere
181 in an `a.out' format file to store alignment information on the
182 contained data, so when a file is linked from `b.out' and an `a.out'
183 image is produced, alignment information will not propagate to the
184 output file. (The linker will still use the alignment information
185 internally, so the link is performed correctly).
187 Another example is COFF section names. COFF files may contain an
188 unlimited number of sections, each one with a textual section name. If
189 the target of the link is a format which does not have many sections
190 (e.g., `a.out') or has sections without names (e.g., the Oasys format),
191 the link cannot be done simply. You can circumvent this problem by
192 describing the desired input-to-output section mapping with the linker
195 _Information can be lost during canonicalization._ The BFD internal
196 canonical form of the external formats is not exhaustive; there are
197 structures in input formats for which there is no direct representation
198 internally. This means that the BFD back ends cannot maintain all
199 possible data richness through the transformation between external to
200 internal and back to external formats.
202 This limitation is only a problem when an application reads one
203 format and writes another. Each BFD back end is responsible for
204 maintaining as much data as possible, and the internal BFD canonical
205 form has structures which are opaque to the BFD core, and exported only
206 to the back ends. When a file is read in one format, the canonical form
207 is generated for BFD and the application. At the same time, the back
208 end saves away any information which may otherwise be lost. If the data
209 is then written back in the same format, the back end routine will be
210 able to use the canonical form provided by the BFD core as well as the
211 information it prepared earlier. Since there is a great deal of
212 commonality between back ends, there is no information lost when
213 linking or copying big endian COFF to little endian COFF, or `a.out' to
214 `b.out'. When a mixture of formats is linked, the information is only
215 lost from the files whose format differs from the destination.
218 File: bfd.info, Node: Canonical format, Prev: BFD information loss, Up: What BFD Version 2 Can Do
220 1.3.2 The BFD canonical object-file format
221 ------------------------------------------
223 The greatest potential for loss of information occurs when there is the
224 least overlap between the information provided by the source format,
225 that stored by the canonical format, and that needed by the destination
226 format. A brief description of the canonical form may help you
227 understand which kinds of data you can count on preserving across
231 Information stored on a per-file basis includes target machine
232 architecture, particular implementation format type, a demand
233 pageable bit, and a write protected bit. Information like Unix
234 magic numbers is not stored here--only the magic numbers' meaning,
235 so a `ZMAGIC' file would have both the demand pageable bit and the
236 write protected text bit set. The byte order of the target is
237 stored on a per-file basis, so that big- and little-endian object
238 files may be used with one another.
241 Each section in the input file contains the name of the section,
242 the section's original address in the object file, size and
243 alignment information, various flags, and pointers into other BFD
247 Each symbol contains a pointer to the information for the object
248 file which originally defined it, its name, its value, and various
249 flag bits. When a BFD back end reads in a symbol table, it
250 relocates all symbols to make them relative to the base of the
251 section where they were defined. Doing this ensures that each
252 symbol points to its containing section. Each symbol also has a
253 varying amount of hidden private data for the BFD back end. Since
254 the symbol points to the original file, the private data format
255 for that symbol is accessible. `ld' can operate on a collection
256 of symbols of wildly different formats without problems.
258 Normal global and simple local symbols are maintained on output,
259 so an output file (no matter its format) will retain symbols
260 pointing to functions and to global, static, and common variables.
261 Some symbol information is not worth retaining; in `a.out', type
262 information is stored in the symbol table as long symbol names.
263 This information would be useless to most COFF debuggers; the
264 linker has command line switches to allow users to throw it away.
266 There is one word of type information within the symbol, so if the
267 format supports symbol type information within symbols (for
268 example, COFF, IEEE, Oasys) and the type is simple enough to fit
269 within one word (nearly everything but aggregates), the
270 information will be preserved.
273 Each canonical BFD relocation record contains a pointer to the
274 symbol to relocate to, the offset of the data to relocate, the
275 section the data is in, and a pointer to a relocation type
276 descriptor. Relocation is performed by passing messages through
277 the relocation type descriptor and the symbol pointer. Therefore,
278 relocations can be performed on output data using a relocation
279 method that is only available in one of the input formats. For
280 instance, Oasys provides a byte relocation format. A relocation
281 record requesting this relocation type would point indirectly to a
282 routine to perform this, so the relocation may be performed on a
283 byte being written to a 68k COFF file, even though 68k COFF has no
284 such relocation type.
287 Object formats can contain, for debugging purposes, some form of
288 mapping between symbols, source line numbers, and addresses in the
289 output file. These addresses have to be relocated along with the
290 symbol information. Each symbol with an associated list of line
291 number records points to the first record of the list. The head
292 of a line number list consists of a pointer to the symbol, which
293 allows finding out the address of the function whose line number
294 is being described. The rest of the list is made up of pairs:
295 offsets into the section and line numbers. Any format which can
296 simply derive this information can pass it successfully between
297 formats (COFF, IEEE and Oasys).

567 calling `bfd_get_error'. If that returns `bfd_error_system_call', then
570 The easiest way to report a BFD error to the user is to use
573 2.2.1 Type `bfd_error_type'
574 ---------------------------
576 The values returned by `bfd_get_error' are defined by the enumerated
577 type `bfd_error_type'.
580 typedef enum bfd_error
582 bfd_error_no_error = 0,

606 2.2.1.1 `bfd_get_error'
607 .......................

612 Return the current BFD error condition.
614 2.2.1.2 `bfd_set_error'
615 .......................
618 void bfd_set_error (bfd_error_type error_tag, ...);
620 Set the BFD error condition to be ERROR_TAG. If ERROR_TAG is
621 bfd_error_on_input, then this function takes two more parameters, the
622 input bfd where the error occurred, and the bfd_error_type error.
628 const char *bfd_errmsg (bfd_error_type error_tag);
630 Return a string describing the error ERROR_TAG, or the system error if
631 ERROR_TAG is `bfd_error_system_call'.
637 void bfd_perror (const char *message);
639 Print to the standard error stream a string describing the last BFD
640 error that occurred, or the last system error if the last BFD error was
641 a system call failure. If MESSAGE is non-NULL and non-empty, the error
642 string printed is preceded by MESSAGE, a colon, and a space. It is
643 followed by a newline.
645 2.2.2 BFD error handler

648 Some BFD functions want to print messages describing the problem. They
649 call a BFD error handler function. This function may be overridden by
652 The BFD error handler acts like printf.

661 bfd_error_handler_type bfd_set_error_handler (bfd_error_handler_type);
663 Set the BFD error handler function. Returns the previous function.
665 2.2.2.2 `bfd_set_error_program_name'
666 ....................................
669 void bfd_set_error_program_name (const char *);
671 Set the program name to use when printing a BFD error. This is printed
672 before the error message followed by a colon and space. The string
673 must not be changed after it is passed to this function.
675 2.2.2.3 `bfd_get_error_handler'
676 ...............................
679 bfd_error_handler_type bfd_get_error_handler (void);
681 Return the BFD error handler function.
686 2.3.1 Miscellaneous functions
687 -----------------------------
689 2.3.1.1 `bfd_get_reloc_upper_bound'
690 ...................................
693 long bfd_get_reloc_upper_bound (bfd *abfd, asection *sect);
695 Return the number of bytes required to store the relocation information
696 associated with section SECT attached to bfd ABFD. If an error occurs,
699 2.3.1.2 `bfd_canonicalize_reloc'
700 ................................
703 long bfd_canonicalize_reloc
704 (bfd *abfd, asection *sec, arelent **loc, asymbol **syms);
706 Call the back end associated with the open BFD ABFD and translate the
707 external form of the relocation information attached to SEC into the
708 internal canonical form. Place the table into memory at LOC, which has
709 been preallocated, usually by a call to `bfd_get_reloc_upper_bound'.
710 Returns the number of relocs, or -1 on error.
712 The SYMS table is also needed for horrible internal magic reasons.
714 2.3.1.3 `bfd_set_reloc'
715 .......................
719 (bfd *abfd, asection *sec, arelent **rel, unsigned int count);
721 Set the relocation pointer and count within section SEC to the values
722 REL and COUNT. The argument ABFD is ignored.
724 2.3.1.4 `bfd_set_file_flags'
725 ............................
728 bfd_boolean bfd_set_file_flags (bfd *abfd, flagword flags);
730 Set the flag word in the BFD ABFD to the value FLAGS.
733 * `bfd_error_wrong_format' - The target bfd was not of object format.
735 * `bfd_error_invalid_operation' - The target bfd was open for
738 * `bfd_error_invalid_operation' - The flag word contained a bit
739 which was not applicable to the type of file. E.g., an attempt
740 was made to set the `D_PAGED' bit on a BFD format which does not
741 support demand paging.
743 2.3.1.5 `bfd_get_arch_size'
744 ...........................
747 int bfd_get_arch_size (bfd *abfd);
749 Returns the architecture address size, in bits, as determined by the
750 object file's format. For ELF, this information is included in the
754 Returns the arch size in bits if known, `-1' otherwise.
756 2.3.1.6 `bfd_get_sign_extend_vma'
757 .................................
760 int bfd_get_sign_extend_vma (bfd *abfd);
762 Indicates if the target architecture "naturally" sign extends an
763 address. Some architectures implicitly sign extend address values when
764 they are converted to types larger than the size of an address. For
765 instance, bfd_get_start_address() will return an address sign extended
766 to fill a bfd_vma when this is the case.
769 Returns `1' if the target architecture is known to sign extend
770 addresses, `0' if the target architecture is known to not sign extend
771 addresses, and `-1' otherwise.
773 2.3.1.7 `bfd_set_start_address'
774 ...............................
777 bfd_boolean bfd_set_start_address (bfd *abfd, bfd_vma vma);
779 Make VMA the entry point of output BFD ABFD.
782 Returns `TRUE' on success, `FALSE' otherwise.
784 2.3.1.8 `bfd_get_gp_size'
785 .........................
788 unsigned int bfd_get_gp_size (bfd *abfd);
790 Return the maximum size of objects to be optimized using the GP
791 register under MIPS ECOFF. This is typically set by the `-G' argument
792 to the compiler, assembler or linker.
794 2.3.1.9 `bfd_set_gp_size'
795 .........................
798 void bfd_set_gp_size (bfd *abfd, unsigned int i);
800 Set the maximum size of objects to be optimized using the GP register
801 under ECOFF or MIPS ELF. This is typically set by the `-G' argument to
802 the compiler, assembler or linker.
804 2.3.1.10 `bfd_scan_vma'
805 .......................
808 bfd_vma bfd_scan_vma (const char *string, const char **end, int base);
810 Convert, like `strtoul', a numerical expression STRING into a `bfd_vma'
811 integer, and return that integer. (Though without as many bells and
812 whistles as `strtoul'.) The expression is assumed to be unsigned
813 (i.e., positive). If given a BASE, it is used as the base for
814 conversion. A base of 0 causes the function to interpret the string in
815 hex if a leading "0x" or "0X" is found, otherwise in octal if a leading
816 zero is found, otherwise in decimal.
818 If the value would overflow, the maximum `bfd_vma' value is returned.

821 .......................................
824 bfd_boolean bfd_copy_private_header_data (bfd *ibfd, bfd *obfd);
826 Copy private BFD header information from the BFD IBFD to the the BFD
827 OBFD. This copies information that may require sections to exist, but
828 does not require symbol tables. Return `true' on success, `false' on
829 error. Possible error returns are:

980 2.3.1.16 `bfd_alt_mach_code'
981 ............................
984 bfd_boolean bfd_alt_mach_code (bfd *abfd, int alternative);
986 When more than one machine code number is available for the same
987 machine type, this function can be used to switch between the preferred
988 one (alternative == 0) and any others. Currently, only ELF supports
989 this feature, with up to two alternate machine codes.

1003 2.3.1.17 `bfd_preserve_save'
1004 ............................
1007 bfd_boolean bfd_preserve_save (bfd *, struct bfd_preserve *);
1009 When testing an object for compatibility with a particular target
1010 back-end, the back-end object_p function needs to set up certain fields
1011 in the bfd on successfully recognizing the object. This typically
1012 happens in a piecemeal fashion, with failures possible at many points.
1013 On failure, the bfd is supposed to be restored to its initial state,
1014 which is virtually impossible. However, restoring a subset of the bfd
1015 state works in practice. This function stores the subset and
1016 reinitializes the bfd.
1018 2.3.1.18 `bfd_preserve_restore'
1019 ...............................
1022 void bfd_preserve_restore (bfd *, struct bfd_preserve *);
1024 This function restores bfd state saved by bfd_preserve_save. If MARKER
1025 is non-NULL in struct bfd_preserve then that block and all subsequently
1026 bfd_alloc'd memory is freed.
1028 2.3.1.19 `bfd_preserve_finish'

1035 bfd_preserve_save is no longer needed. ie. when the back-end object_p
1036 function returns with success.

1059 ......................................
1062 bfd_vma bfd_emul_get_commonpagesize (const char *);
1064 Returns the common page size, in bytes, as determined by emulation.

1079 .......................
1082 char *bfd_demangle (bfd *, const char *, int);
1084 Wrapper around cplus_demangle. Strips leading underscores and other
1085 such chars that would otherwise confuse the demangler. If passed a g++
1086 v3 ABI mangled name, returns a buffer allocated with malloc holding the
1087 demangled name. Returns NULL otherwise and on memory alloc failure.

1090 ...........................
1093 The `struct bfd_iovec' contains the internal file I/O class. Each

1119 2.3.1.26 `bfd_get_mtime'
1120 ........................
1123 long bfd_get_mtime (bfd *abfd);
1125 Return the file modification time (as read from the file system, or
1126 from the archive header for archive members).
1128 2.3.1.27 `bfd_get_size'
1129 .......................
1132 file_ptr bfd_get_size (bfd *abfd);
1134 Return the file size (as read from file system) for the file associated
1137 The initial motivation for, and use of, this routine is not so we
1138 can get the exact size of the object the BFD applies to, since that
1139 might not be generally possible (archive members for example). It
1140 would be ideal if someone could eventually modify it so that such
1141 results were guaranteed.
1143 Instead, we want to ask questions like "is this NNN byte sized
1144 object I'm about to try read from file offset YYY reasonable?" As as
1145 example of where we might do this, some object formats use string
1146 tables for which the first `sizeof (long)' bytes of the table contain
1147 the size of the table itself, including the size bytes. If an
1148 application tries to read what it thinks is one of these string tables,
1149 without some way to validate the size, and for some reason the size is
1150 wrong (byte swapping error, wrong location for the string table, etc.),
1151 the only clue is likely to be a read error when it tries to read the
1152 table, or a "virtual memory exhausted" error when it tries to allocate
1153 15 bazillon bytes of space for the 15 bazillon byte table it is about
1154 to read. This function at least allows us to answer the question, "is
1155 the size reasonable?".

1176 File: bfd.info, Node: Memory Usage, Next: Initialization, Prev: BFD front end, Up: BFD front end
1181 BFD keeps all of its internal structures in obstacks. There is one
1182 obstack per open BFD file, into which the current state is stored. When
1183 a BFD is closed, the obstack is deleted, and so everything which has
1184 been allocated by BFD for the closing file is thrown away.
1186 BFD does not free anything created by an application, but pointers
1187 into `bfd' structures become invalid on a `bfd_close'; for example,
1188 after a `bfd_close' the vector passed to `bfd_canonicalize_symtab' is
1189 still around, since it has been allocated by the application, but the
1190 data that it pointed to are lost.
1192 The general rule is to not close a BFD until all operations dependent
1193 upon data from the BFD have been completed, or all the data from within
1194 the file has been copied. To help with the management of memory, there
1195 is a function (`bfd_alloc_size') which returns the number of bytes in
1196 obstacks associated with the supplied BFD. This could be used to select
1197 the greediest open BFD, close it to reclaim the memory, perform some
1198 operation and reopen the BFD again, to get a fresh copy of the data

1210 These are the functions that handle initializing a BFD.

1227 The raw data contained within a BFD is maintained through the section
1228 abstraction. A single BFD may have any number of sections. It keeps
1229 hold of them by pointing to the first; each one points to the next in
1232 Sections are supported in BFD in `section.c'.

1239 * section prototypes::
1242 File: bfd.info, Node: Section Input, Next: Section Output, Prev: Sections, Up: Sections
1247 When a BFD is opened for reading, the section structures are created
1248 and attached to the BFD.
1250 Each section has a name which describes the section in the outside
1251 world--for example, `a.out' would contain at least three sections,
1252 called `.text', `.data' and `.bss'.
1254 Names need not be unique; for example a COFF file may have several
1255 sections named `.data'.
1257 Sometimes a BFD will contain more than the "natural" number of
1258 sections. A back end may attach other sections containing constructor
1259 data, or an application may add a section (using `bfd_make_section') to
1260 the sections attached to an already open BFD. For example, the linker
1261 creates an extra section `COMMON' for each input file's BFD to hold
1262 information about common storage.
1264 The raw data is not necessarily read in when the section descriptor
1265 is created. Some targets may leave the data in place until a
1266 `bfd_get_section_contents' call is made. Other back ends may read in
1267 all the data at once. For example, an S-record file has to be read
1268 once to determine the size of the data. An IEEE-695 file doesn't
1269 contain raw data in sections, but data and relocation expressions
1270 intermixed, so the data area has to be parsed to get out the data and
1274 File: bfd.info, Node: Section Output, Next: typedef asection, Prev: Section Input, Up: Sections
1276 2.6.2 Section output
1277 --------------------
1279 To write a new object style BFD, the various sections to be written
1280 have to be created. They are attached to the BFD in the same way as
1281 input sections; data is written to the sections using
1282 `bfd_set_section_contents'.
1284 Any program that creates or combines sections (e.g., the assembler
1285 and linker) must use the `asection' fields `output_section' and
1286 `output_offset' to indicate the file sections to which each section
1287 must be written. (If the section is being created from scratch,
1288 `output_section' should probably point to the section itself and
1289 `output_offset' should probably be zero.)
1291 The data to be written comes from input sections attached (via
1292 `output_section' pointers) to the output sections. The output section
1293 structure can be considered a filter for the input section: the output
1294 section determines the vma of the output data and the name, but the
1295 input section determines the offset into the output section of the data
1298 E.g., to create a section "O", starting at 0x100, 0x123 long,
1299 containing two subsections, "A" at offset 0x0 (i.e., at vma 0x100) and
1300 "B" at offset 0x20 (i.e., at vma 0x120) the `asection' structures would
1306 output_section -----------> section name "O"
1308 section name "B" | size 0x123
1309 output_offset 0x20 |
1311 output_section --------|
1316 The data within a section is stored in a "link_order". These are much
1317 like the fixups in `gas'. The link_order abstraction allows a section
1318 to grow and shrink within itself.
1320 A link_order knows how big it is, and which is the next link_order
1321 and where the raw data for it is; it also points to a list of
1322 relocations which apply to it.
1324 The link_order is used by the linker to perform relaxing on final
1325 code. The compiler creates code which is as big as necessary to make
1326 it work without relaxing, and the user can select whether to relax.
1327 Sometimes relaxing takes a lot of time. The linker runs around the
1328 relocations to see if any are attached to data which can be shrunk, if
1329 so it does it on a link_order by link_order basis.

1864 ------------------------
1866 These are the functions exported by the section handling part of BFD.
1868 2.6.5.1 `bfd_section_list_clear'
1869 ................................
1872 void bfd_section_list_clear (bfd *);
1874 Clears the section list, and also resets the section count and hash
1877 2.6.5.2 `bfd_get_section_by_name'
1878 .................................
1881 asection *bfd_get_section_by_name (bfd *abfd, const char *name);
1883 Run through ABFD and return the one of the `asection's whose name
1884 matches NAME, otherwise `NULL'. *Note Sections::, for more information.
1886 This should only be used in special cases; the normal way to process
1887 all sections of a given name is to use `bfd_map_over_sections' and
1888 `strcmp' on the name (or better yet, base it on the section flags or
1889 something else) for each section.
1891 2.6.5.3 `bfd_get_section_by_name_if'
1892 ....................................
1895 asection *bfd_get_section_by_name_if
1898 bfd_boolean (*func) (bfd *abfd, asection *sect, void *obj),
1901 Call the provided function FUNC for each section attached to the BFD
1902 ABFD whose name matches NAME, passing OBJ as an argument. The function
1903 will be called as if by
1905 func (abfd, the_section, obj);
1907 It returns the first section for which FUNC returns true, otherwise
1910 2.6.5.4 `bfd_get_unique_section_name'
1911 .....................................
1914 char *bfd_get_unique_section_name
1915 (bfd *abfd, const char *templat, int *count);
1917 Invent a section name that is unique in ABFD by tacking a dot and a
1918 digit suffix onto the original TEMPLAT. If COUNT is non-NULL, then it
1919 specifies the first number tried as a suffix to generate a unique name.
1920 The value pointed to by COUNT will be incremented in this case.
1922 2.6.5.5 `bfd_make_section_old_way'
1923 ..................................
1926 asection *bfd_make_section_old_way (bfd *abfd, const char *name);
1928 Create a new empty section called NAME and attach it to the end of the
1929 chain of sections for the BFD ABFD. An attempt to create a section with
1930 a name which is already in use returns its pointer without changing the
1933 It has the funny name since this is the way it used to be before it
1936 Possible errors are:
1937 * `bfd_error_invalid_operation' - If output has already started for
1940 * `bfd_error_no_memory' - If memory allocation fails.
1942 2.6.5.6 `bfd_make_section_anyway_with_flags'
1943 ............................................
1946 asection *bfd_make_section_anyway_with_flags
1947 (bfd *abfd, const char *name, flagword flags);
1949 Create a new empty section called NAME and attach it to the end of the
1950 chain of sections for ABFD. Create a new section even if there is
1951 already a section with that name. Also set the attributes of the new
1952 section to the value FLAGS.
1954 Return `NULL' and set `bfd_error' on error; possible errors are:
1955 * `bfd_error_invalid_operation' - If output has already started for
1958 * `bfd_error_no_memory' - If memory allocation fails.
1960 2.6.5.7 `bfd_make_section_anyway'
1961 .................................
1964 asection *bfd_make_section_anyway (bfd *abfd, const char *name);
1966 Create a new empty section called NAME and attach it to the end of the
1967 chain of sections for ABFD. Create a new section even if there is
1968 already a section with that name.
1970 Return `NULL' and set `bfd_error' on error; possible errors are:
1971 * `bfd_error_invalid_operation' - If output has already started for
1974 * `bfd_error_no_memory' - If memory allocation fails.
1976 2.6.5.8 `bfd_make_section_with_flags'
1977 .....................................
1980 asection *bfd_make_section_with_flags
1981 (bfd *, const char *name, flagword flags);
1983 Like `bfd_make_section_anyway', but return `NULL' (without calling
1984 bfd_set_error ()) without changing the section chain if there is
1985 already a section named NAME. Also set the attributes of the new
1986 section to the value FLAGS. If there is an error, return `NULL' and set
1989 2.6.5.9 `bfd_make_section'
1990 ..........................
1993 asection *bfd_make_section (bfd *, const char *name);
1995 Like `bfd_make_section_anyway', but return `NULL' (without calling
1996 bfd_set_error ()) without changing the section chain if there is
1997 already a section named NAME. If there is an error, return `NULL' and
2000 2.6.5.10 `bfd_set_section_flags'
2001 ................................
2004 bfd_boolean bfd_set_section_flags
2005 (bfd *abfd, asection *sec, flagword flags);
2007 Set the attributes of the section SEC in the BFD ABFD to the value
2008 FLAGS. Return `TRUE' on success, `FALSE' on error. Possible error
2011 * `bfd_error_invalid_operation' - The section cannot have one or
2012 more of the attributes requested. For example, a .bss section in
2013 `a.out' may not have the `SEC_HAS_CONTENTS' field set.
2015 2.6.5.11 `bfd_map_over_sections'
2016 ................................
2019 void bfd_map_over_sections

2024 Call the provided function FUNC for each section attached to the BFD
2025 ABFD, passing OBJ as an argument. The function will be called as if by
2027 func (abfd, the_section, obj);
2029 This is the preferred method for iterating over sections; an

2076 starting in memory at DATA. The data is written to the output section
2077 starting at offset OFFSET for COUNT octets.
2079 Normally `TRUE' is returned, else `FALSE'. Possible error returns

2097 The data is read at an offset of OFFSET from the start of the input
2098 section, and is read for COUNT bytes.
2100 If the contents of a constructor with the `SEC_CONSTRUCTOR' flag set
2101 are requested or if the section does not have the `SEC_HAS_CONTENTS'
2102 flag set, then the LOCATION is filled with zeroes. If no errors occur,

2155 BFD tries to maintain as much symbol information as it can when it
2156 moves information from file to file. BFD passes information to
2157 applications though the `asymbol' structure. When the application
2158 requests the symbol table, BFD reads the table in the native form and
2159 translates parts of it into the internal format. To maintain more than
2160 the information passed to applications, some targets keep some
2161 information "behind the scenes" in a structure only the particular back
2162 end knows about. For example, the coff back end keeps the original
2163 symbol table structure as well as the canonical structure when a BFD is
2164 read in. On output, the coff back end can reconstruct the output symbol
2165 table so that no information is lost, even information unique to coff
2166 which BFD doesn't know or understand. If a coff symbol table were read,
2167 but were written through an a.out back end, all the coff specific
2168 information would be lost. The symbol table of a BFD is not necessarily
2169 read in until a canonicalize request is made. Then the BFD back end
2170 fills in a table provided by the application with pointers to the
2171 canonical information. To output symbols, the application provides BFD
2172 with a table of pointers to pointers to `asymbol's. This allows
2173 applications like the linker to output a symbol as it was read, since
2174 the "behind the scenes" information will be still available.

2187 2.7.1 Reading symbols
2188 ---------------------
2190 There are two stages to reading a symbol table from a BFD: allocating
2191 storage, and the actual reading process. This is an excerpt from an
2192 application which reads the symbol table:
2194 long storage_needed;
2195 asymbol **symbol_table;
2196 long number_of_symbols;
2199 storage_needed = bfd_get_symtab_upper_bound (abfd);
2201 if (storage_needed < 0)
2204 if (storage_needed == 0)
2207 symbol_table = xmalloc (storage_needed);
2210 bfd_canonicalize_symtab (abfd, symbol_table);
2212 if (number_of_symbols < 0)
2215 for (i = 0; i < number_of_symbols; i++)
2216 process_symbol (symbol_table[i]);
2218 All storage for the symbols themselves is in an objalloc connected
2219 to the BFD; it is freed when the BFD is closed.
2222 File: bfd.info, Node: Writing Symbols, Next: Mini Symbols, Prev: Reading Symbols, Up: Symbols
2224 2.7.2 Writing symbols
2225 ---------------------
2227 Writing of a symbol table is automatic when a BFD open for writing is
2228 closed. The application attaches a vector of pointers to pointers to
2229 symbols to the BFD being written, and fills in the symbol count. The
2230 close and cleanup code reads through the table provided and performs
2231 all the necessary operations. The BFD output code must always be
2232 provided with an "owned" symbol: one which has come from another BFD,
2233 or one which has been created using `bfd_make_empty_symbol'. Here is an
2234 example showing the creation of a symbol table with only one element:
2243 abfd = bfd_openw ("foo","a.out-sunos-big");
2244 bfd_set_format (abfd, bfd_object);
2245 new = bfd_make_empty_symbol (abfd);
2246 new->name = "dummy_symbol";
2247 new->section = bfd_make_section_old_way (abfd, ".text");
2248 new->flags = BSF_GLOBAL;
2249 new->value = 0x12345;
2254 bfd_set_symtab (abfd, ptrs, 1);
2261 00012345 A dummy_symbol
2263 Many formats cannot represent arbitrary symbol information; for
2264 instance, the `a.out' object format does not allow an arbitrary number
2265 of sections. A symbol pointing to a section which is not one of
2266 `.text', `.data' or `.bss' cannot be described.
2269 File: bfd.info, Node: Mini Symbols, Next: typedef asymbol, Prev: Writing Symbols, Up: Symbols
2274 Mini symbols provide read-only access to the symbol table. They use
2275 less memory space, but require more time to access. They can be useful
2276 for tools like nm or objdump, which may have to handle symbol tables of
2277 extremely large executables.
2279 The `bfd_read_minisymbols' function will read the symbols into
2280 memory in an internal form. It will return a `void *' pointer to a
2281 block of memory, a symbol count, and the size of each symbol. The
2282 pointer is allocated using `malloc', and should be freed by the caller
2283 when it is no longer needed.
2285 The function `bfd_minisymbol_to_symbol' will take a pointer to a
2286 minisymbol, and a pointer to a structure returned by
2287 `bfd_make_empty_symbol', and return a `asymbol' structure. The return
2288 value may or may not be the same as the value from
2289 `bfd_make_empty_symbol' which was passed in.

2601 An archive (or library) is just another BFD. It has a symbol table,
2602 although there's not much a user program will do with it.
2604 The big difference between an archive BFD and an ordinary BFD is
2605 that the archive doesn't have sections. Instead it has a chain of BFDs
2606 that are considered its contents. These BFDs can be manipulated like
2607 any other. The BFDs contained in an archive opened for reading will
2608 all be opened for reading. You may put either input or output BFDs
2609 into an archive opened for output; they will be handled correctly when
2610 the archive is closed.
2612 Use `bfd_openr_next_archived_file' to step through the contents of
2613 an archive opened for input. You don't have to read the entire archive
2614 if you don't want to! Read it until you find what you want.
2616 Archive contents of output BFDs are chained through the `next'
2617 pointer in a BFD. The first one is findable through the `archive_head'
2618 slot of the archive. Set it with `bfd_set_archive_head' (q.v.). A
2619 given BFD may be in only one open output archive at a time.
2621 As expected, the BFD archive code is more general than the archive
2622 code of any given environment. BFD archives may contain files of
2623 different formats (e.g., a.out and coff) and even different
2624 architectures. You may even place archives recursively into archives!
2626 This can cause unexpected confusion, since some archive formats are
2627 more expressive than others. For instance, Intel COFF archives can
2628 preserve long filenames; SunOS a.out archives cannot. If you move a
2629 file from the first to the second format and back again, the filename
2630 may be truncated. Likewise, different a.out environments have different
2631 conventions as to how they truncate filenames, whether they preserve
2632 directory names in filenames, etc. When interoperating with native
2633 tools, be sure your files are homogeneous.
2635 Beware: most of these formats do not react well to the presence of
2636 spaces in filenames. We do the best we can, but can't always handle
2637 this case due to restrictions in the format of archives. Many Unix
2638 utilities are braindead in regards to spaces and such in filenames
2639 anyway, so this shouldn't be much of a restriction.
2641 Archives are supported in BFD in `archive.c'.

2690 A format is a BFD concept of high level file contents type. The formats
2691 supported by BFD are:
2694 The BFD may contain data, symbols, relocations and debug info.
2697 The BFD contains other BFDs and an optional index.
2700 The BFD contains the result of an executable core dump.
2702 2.9.1 File format functions
2703 ---------------------------
2705 2.9.1.1 `bfd_check_format'
2706 ..........................
2709 bfd_boolean bfd_check_format (bfd *abfd, bfd_format format);
2711 Verify if the file attached to the BFD ABFD is compatible with the
2712 format FORMAT (i.e., one of `bfd_object', `bfd_archive' or `bfd_core').
2714 If the BFD has been set to a specific target before the call, only
2715 the named target and format combination is checked. If the target has
2716 not been set, or has been set to `default', then all the known target
2717 backends is interrogated to determine a match. If the default target
2718 matches, it is used. If not, exactly one target must recognize the
2719 file, or an error results.
2721 The function returns `TRUE' on success, otherwise `FALSE' with one
2722 of the following error codes:
2724 * `bfd_error_invalid_operation' - if `format' is not one of
2725 `bfd_object', `bfd_archive' or `bfd_core'.
2727 * `bfd_error_system_call' - if an error occured during a read - even
2728 some file mismatches can cause bfd_error_system_calls.
2730 * `file_not_recognised' - none of the backends recognised the file
2733 * `bfd_error_file_ambiguously_recognized' - more than one backend
2734 recognised the file format.
2736 2.9.1.2 `bfd_check_format_matches'
2737 ..................................
2740 bfd_boolean bfd_check_format_matches
2741 (bfd *abfd, bfd_format format, char ***matching);
2743 Like `bfd_check_format', except when it returns FALSE with `bfd_errno'
2744 set to `bfd_error_file_ambiguously_recognized'. In that case, if
2745 MATCHING is not NULL, it will be filled in with a NULL-terminated list
2746 of the names of the formats that matched, allocated with `malloc'.
2747 Then the user may choose a format and try again.
2749 When done with the list that MATCHING points to, the caller should
2752 2.9.1.3 `bfd_set_format'
2753 ........................
2756 bfd_boolean bfd_set_format (bfd *abfd, bfd_format format);
2758 This function sets the file format of the BFD ABFD to the format
2759 FORMAT. If the target set in the BFD does not support the format
2760 requested, the format is invalid, or the BFD is not open for writing,
2761 then an error occurs.
2763 2.9.1.4 `bfd_format_string'
2764 ...........................
2767 const char *bfd_format_string (bfd_format format);
2769 Return a pointer to a const string `invalid', `object', `archive',
2770 `core', or `unknown', depending upon the value of FORMAT.

2778 BFD maintains relocations in much the same way it maintains symbols:
2779 they are left alone until required, then read in en-masse and
2780 translated into an internal form. A common routine
2781 `bfd_perform_relocation' acts upon the canonical form to do the fixup.
2783 Relocations are maintained on a per section basis, while symbols are
2784 maintained on a per BFD basis.
2786 All that a back end has to do to fit the BFD interface is to create
2787 a `struct reloc_cache_entry' for each relocation in a particular
2788 section, and fill in the right bits of the structures.
2796 File: bfd.info, Node: typedef arelent, Next: howto manager, Prev: Relocations, Up: Relocations
2798 2.10.1 typedef arelent
2799 ----------------------
2801 This is the structure of a relocation entry:
2804 typedef enum bfd_reloc_status
2806 /* No errors detected. */
2809 /* The relocation was performed, but there was an overflow. */
2812 /* The address to relocate was not within the section supplied. */
2813 bfd_reloc_outofrange,
2815 /* Used by special functions. */
2818 /* Unsupported relocation size requested. */
2819 bfd_reloc_notsupported,
2824 /* The symbol to relocate against was undefined. */
2825 bfd_reloc_undefined,
2827 /* The relocation was performed, but may not be ok - presently
2828 generated only when linking i960 coff files with i960 b.out
2829 symbols. If this type is returned, the error_message argument
2830 to bfd_perform_relocation will be set. */
2833 bfd_reloc_status_type;
2836 typedef struct reloc_cache_entry
2838 /* A pointer into the canonical table of pointers. */
2839 struct bfd_symbol **sym_ptr_ptr;
2841 /* offset in section. */
2842 bfd_size_type address;
2844 /* addend for relocation value. */
2847 /* Pointer to how to perform the required relocation. */
2848 reloc_howto_type *howto;
2853 Here is a description of each of the fields within an `arelent':
2856 The symbol table pointer points to a pointer to the symbol
2857 associated with the relocation request. It is the pointer into the
2858 table returned by the back end's `canonicalize_symtab' action. *Note
2859 Symbols::. The symbol is referenced through a pointer to a pointer so
2860 that tools like the linker can fix up all the symbols of the same name
2861 by modifying only one pointer. The relocation routine looks in the
2862 symbol and uses the base of the section the symbol is attached to and
2863 the value of the symbol as the initial relocation offset. If the symbol
2864 pointer is zero, then the section provided is looked up.
2867 The `address' field gives the offset in bytes from the base of the
2868 section data which owns the relocation record to the first byte of
2869 relocatable information. The actual data relocated will be relative to
2870 this point; for example, a relocation type which modifies the bottom
2871 two bytes of a four byte word would not touch the first byte pointed to
2872 in a big endian world.
2875 The `addend' is a value provided by the back end to be added (!) to
2876 the relocation offset. Its interpretation is dependent upon the howto.
2877 For example, on the 68k the code:
2882 return foo[0x12345678];
2885 Could be compiled into:
2893 This could create a reloc pointing to `foo', but leave the offset in
2894 the data, something like:
2896 RELOCATION RECORDS FOR [.text]:
2900 00000000 4e56 fffc ; linkw fp,#-4
2901 00000004 1039 1234 5678 ; moveb @#12345678,d0
2902 0000000a 49c0 ; extbl d0
2903 0000000c 4e5e ; unlk fp
2906 Using coff and an 88k, some instructions don't have enough space in
2907 them to represent the full address range, and pointers have to be
2908 loaded in two parts. So you'd get something like:
2910 or.u r13,r0,hi16(_foo+0x12345678)
2911 ld.b r2,r13,lo16(_foo+0x12345678)
2914 This should create two relocs, both pointing to `_foo', and with
2915 0x12340000 in their addend field. The data would consist of:
2917 RELOCATION RECORDS FOR [.text]:
2919 00000002 HVRT16 _foo+0x12340000
2920 00000006 LVRT16 _foo+0x12340000
2922 00000000 5da05678 ; or.u r13,r0,0x5678
2923 00000004 1c4d5678 ; ld.b r2,r13,0x5678
2924 00000008 f400c001 ; jmp r1
2926 The relocation routine digs out the value from the data, adds it to
2927 the addend to get the original offset, and then adds the value of
2928 `_foo'. Note that all 32 bits have to be kept around somewhere, to cope
2929 with carry from bit 15 to bit 16.
2931 One further example is the sparc and the a.out format. The sparc has
2932 a similar problem to the 88k, in that some instructions don't have room
2933 for an entire offset, but on the sparc the parts are created in odd
2934 sized lumps. The designers of the a.out format chose to not use the
2935 data within the section for storing part of the offset; all the offset
2936 is kept within the reloc. Anything in the data should be ignored.
2939 sethi %hi(_foo+0x12345678),%g2
2940 ldsb [%g2+%lo(_foo+0x12345678)],%i0
2944 Both relocs contain a pointer to `foo', and the offsets contain junk.
2946 RELOCATION RECORDS FOR [.text]:
2948 00000004 HI22 _foo+0x12345678
2949 00000008 LO10 _foo+0x12345678
2951 00000000 9de3bf90 ; save %sp,-112,%sp
2952 00000004 05000000 ; sethi %hi(_foo+0),%g2
2953 00000008 f048a000 ; ldsb [%g2+%lo(_foo+0)],%i0
2954 0000000c 81c7e008 ; ret
2955 00000010 81e80000 ; restore
2958 The `howto' field can be imagined as a relocation instruction. It is
2959 a pointer to a structure which contains information on what to do with
2960 all of the other information in the reloc record and data section. A
2961 back end would normally have a relocation instruction set and turn
2962 relocations into pointers to the correct structure on input - but it
2963 would be possible to create each howto field on demand.

3174 If OUTPUT_BFD is supplied to this function, the generated image will be
3175 relocatable; the relocations are copied to the output file after they
3176 have been changed to reflect the new state of the world. There are two
3177 ways of reflecting the results of partial linkage in an output file: by
3178 modifying the output data in place, and by modifying the relocation
3179 record. Some native formats (e.g., basic a.out and basic coff) have no
3180 way of specifying an addend in the relocation type, so the addend has
3181 to go in the output data. This is no big deal since in these formats
3182 the output data slot will always be big enough for the addend. Complex
3183 reloc types with addends were invented to solve just this problem. The
3184 ERROR_MESSAGE argument is set to an error message if this return
3185 `bfd_reloc_dangerous'.

3196 char **error_message);
3198 This looks remarkably like `bfd_perform_relocation', except it does not
3199 expect that the section contents have been filled in. I.e., it's
3200 suitable for use when creating, rather than applying a relocation.

3219 The insides of a reloc code. The idea is that, eventually, there will
3220 be one enumerator for every type of relocation we ever do. Pass one of
3221 these values to `bfd_reloc_type_lookup', and it'll return a howto
3224 This does mean that the application must determine the correct
3225 enumerator value; you can't get a howto pointer from a random set of

3300 displacement (<<32_PCREL_S2>> - 32 bits, shifted 2) is used on the

3421 Alpha ECOFF and ELF relocations. Some of these treat the symbol or
3422 "addend" in some special way. For GPDISP_HI16 ("gpdisp")
3423 relocations, the symbol is ignored when writing; when reading, it
3424 will be the absolute section symbol. The addend is the
3425 displacement in bytes of the "lda" instruction from the "ldah"
3426 instruction (which is at the address of this reloc).
3428 -- : BFD_RELOC_ALPHA_GPDISP_LO16
3429 For GPDISP_LO16 ("ignore") relocations, the symbol is handled as
3430 with GPDISP_HI16 relocs. The addend is ignored when writing the
3431 relocations out, and is filled in with the file's GP value on
3432 reading, for convenience.
3434 -- : BFD_RELOC_ALPHA_GPDISP
3435 The ELF GPDISP relocation is exactly the same as the GPDISP_HI16
3436 relocation except that there is no accompanying GPDISP_LO16
3439 -- : BFD_RELOC_ALPHA_LITERAL
3440 -- : BFD_RELOC_ALPHA_ELF_LITERAL
3441 -- : BFD_RELOC_ALPHA_LITUSE
3442 The Alpha LITERAL/LITUSE relocs are produced by a symbol reference;
3443 the assembler turns it into a LDQ instruction to load the address
3444 of the symbol, and then fills in a register in the real
3447 The LITERAL reloc, at the LDQ instruction, refers to the .lita
3448 section symbol. The addend is ignored when writing, but is filled
3449 in with the file's GP value on reading, for convenience, as with
3450 the GPDISP_LO16 reloc.
3452 The ELF_LITERAL reloc is somewhere between 16_GOTOFF and
3453 GPDISP_LO16. It should refer to the symbol to be referenced, as
3454 with 16_GOTOFF, but it generates output not based on the position
3455 within the .got section, but relative to the GP value chosen for
3456 the file during the final link stage.
3458 The LITUSE reloc, on the instruction using the loaded address,
3459 gives information to the linker that it might be able to use to
3460 optimize away some literal section references. The symbol is
3461 ignored (read as the absolute section symbol), and the "addend"
3462 indicates the type of instruction using the register: 1 - "memory"
3463 fmt insn 2 - byte-manipulation (byte offset reg) 3 - jsr (target
3466 -- : BFD_RELOC_ALPHA_HINT
3467 The HINT relocation indicates a value that should be filled into
3468 the "hint" field of a jmp/jsr/ret instruction, for possible branch-
3469 prediction logic which may be provided on some processors.
3471 -- : BFD_RELOC_ALPHA_LINKAGE
3472 The LINKAGE relocation outputs a linkage pair in the object file,
3473 which is filled by the linker.
3475 -- : BFD_RELOC_ALPHA_CODEADDR
3476 The CODEADDR relocation outputs a STO_CA in the object file, which
3477 is filled by the linker.

3484 -- : BFD_RELOC_ALPHA_BRSGP
3485 Like BFD_RELOC_23_PCREL_S2, except that the source and target must
3486 share a common GP, and the target address is adjusted for

4830 These two relocations are used by the linker to determine which of
4831 the entries in a C++ virtual function table are actually used.
4832 When the -gc-sections option is given, the linker will zero out
4833 the entries that are not used, so that the code for those
4834 functions need not be included in the output.
4836 VTABLE_INHERIT is a zero-space relocation used to describe to the
4837 linker the inheritance tree of a C++ virtual function table. The
4838 relocation's symbol should be the parent class' vtable, and the
4839 relocation should be located at the child vtable.
4841 VTABLE_ENTRY is a zero-space relocation that describes the use of a
4842 virtual function table entry. The reloc's symbol should refer to
4843 the table of the class mentioned in the code. Off of that base,
4844 an offset describes the entry that is being used. For Rela hosts,
4845 this offset is stored in the reloc's addend. For Rel hosts, we
4846 are forced to put this offset in the reloc's section offset.

5450 Each port of BFD to a different machine requires the creation of a
5451 target back end. All the back end provides to the root part of BFD is a
5452 structure containing pointers to functions which perform certain low
5453 level operations on files. BFD translates the applications's requests
5454 through a pointer into calls to the back end routines.
5456 When a file is opened with `bfd_openr', its format and target are
5457 unknown. BFD uses various mechanisms to determine how to interpret the
5458 file. The operations performed are:
5460 * Create a BFD by calling the internal routine `_bfd_new_bfd', then
5461 call `bfd_find_target' with the target string supplied to
5462 `bfd_openr' and the new BFD pointer.
5464 * If a null target string was provided to `bfd_find_target', look up
5465 the environment variable `GNUTARGET' and use that as the target
5468 * If the target string is still `NULL', or the target string is
5469 `default', then use the first item in the target vector as the
5470 target type, and set `target_defaulted' in the BFD to cause
5471 `bfd_check_format' to loop through all the targets. *Note
5472 bfd_target::. *Note Formats::.
5474 * Otherwise, inspect the elements in the target vector one by one,
5475 until a match on target name is found. When found, use it.
5477 * Otherwise return the error `bfd_error_invalid_target' to
5480 * `bfd_openr' attempts to open the file using `bfd_open_file', and
5482 Once the BFD has been opened and the target selected, the file
5483 format may be determined. This is done by calling `bfd_check_format' on
5484 the BFD with a suggested format. If `target_defaulted' has been set,
5485 each possible target type is tried to see if it recognizes the
5486 specified format. `bfd_check_format' returns `TRUE' when the caller

5500 This structure contains everything that BFD knows about a target. It
5501 includes things like its byte order, name, and which routines to call
5502 to do various operations.
5504 Every BFD points to a target structure with its `xvec' member.
5506 The macros below are used to dispatch to functions through the
5507 `bfd_target' vector. They are used in a number of macros further down
5508 in `bfd.h', and are also used when calling various routines by hand
5509 inside the BFD implementation. The ARGLIST argument must be
5510 parenthesized; it contains all the arguments to the called function.
5512 They make the documentation (more) unpleasant to read, so if someone
5513 wants to fix this and not break the above, please do.

5521 ((*((bfd)->xvec->message)) arglist) : \
5522 (bfd_assert (__FILE__,__LINE__), NULL))
5524 For operations which index on the BFD format:
5525 #define BFD_SEND_FMT(bfd, message, arglist) \
5526 (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist)

5533 (bfd_assert (__FILE__,__LINE__), NULL))
5535 This is the structure which defines the type of BFD this is. The
5536 `xvec' member of the struct `bfd' itself points here. Each module that
5537 implements access to a different target under BFD, defines one of these.
5539 FIXME, these names should be rationalised with the names of the
5540 entry points which call them. Too bad we can't have one macro to define

5922 2.12.1.1 `bfd_set_default_target'
5923 .................................
5926 bfd_boolean bfd_set_default_target (const char *name);
5928 Set the default target vector to use when recognizing a BFD. This
5929 takes the name of the target, which may be a BFD target name or a
5930 configuration triplet.
5932 2.12.1.2 `bfd_find_target'

5936 const bfd_target *bfd_find_target (const char *target_name, bfd *abfd);
5938 Return a pointer to the transfer vector for the object target named
5939 TARGET_NAME. If TARGET_NAME is `NULL', choose the one in the
5940 environment variable `GNUTARGET'; if that is null or not defined, then
5941 choose the first entry in the target list. Passing in the string
5942 "default" or setting the environment variable to "default" will cause
5943 the first entry in the target list to be returned, and
5944 "target_defaulted" will be set in the BFD if ABFD isn't `NULL'. This
5945 causes `bfd_check_format' to loop over all the targets to find the one
5946 that matches the file being read.
5948 2.12.1.3 `bfd_target_list'
5949 ..........................
5952 const char ** bfd_target_list (void);
5954 Return a freshly malloced NULL-terminated vector of the names of all
5955 the valid BFD targets. Do not modify the names.
5957 2.12.1.4 `bfd_seach_for_target'
5958 ...............................
5961 const bfd_target *bfd_search_for_target
5962 (int (*search_func) (const bfd_target *, void *),
5965 Return a pointer to the first transfer vector in the list of transfer
5966 vectors maintained by BFD that produces a non-zero result when passed
5967 to the function SEARCH_FUNC. The parameter DATA is passed, unexamined,
5968 to the search function.
5971 File: bfd.info, Node: Architectures, Next: Opening and Closing, Prev: Targets, Up: BFD front end
5976 BFD keeps one atom in a BFD describing the architecture of the data
5977 attached to the BFD: a pointer to a `bfd_arch_info_type'.
5979 Pointers to structures can be requested independently of a BFD so
5980 that an architecture's information can be interrogated without access
5983 The architecture information is provided by each architecture
5984 package. The set of default architectures is selected by the macro
5985 `SELECT_ARCHITECTURES'. This is normally set up in the
5986 `config/TARGET.mt' file of your choice. If the name is not defined,
5987 then all the architectures supported are included.
5989 When BFD starts up, all the architectures are called with an
5990 initialize method. It is up to the architecture back end to insert as
5991 many items into the list of architectures as it wants to; generally
5992 this would be one for each machine and one for the default case (an
5993 item with a machine field of 0).
5995 BFD's idea of an architecture is implemented in `archures.c'.

6003 indicates which processor within the family is in use. The machine
6004 gives a number which distinguishes different versions of the
6005 architecture, containing, for example, 2 and 3 for Intel i960 KA and

6388 ........................
6391 const bfd_arch_info_type *bfd_scan_arch (const char *string);
6393 Figure out if BFD supports any cpu which could be described with the
6394 name STRING. Return a pointer to an `arch_info' structure if a machine

6410 const bfd_arch_info_type *bfd_arch_get_compatible
6411 (const bfd *abfd, const bfd *bbfd, bfd_boolean accept_unknowns);
6413 Determine whether two BFDs' architectures and machine types are
6414 compatible. Calculates the lowest common denominator between the two
6415 architectures and machine types implied by the BFDs and returns a
6416 pointer to an `arch_info' structure describing the compatible machine.
6418 2.13.2.5 `bfd_default_arch_struct'
6419 ..................................
6422 The `bfd_default_arch_struct' is an item of `bfd_arch_info_type' which
6423 has been initialized to a fairly generic state. A BFD starts life by
6424 pointing to this structure, until the correct back end has determined
6425 the real architecture of the file.
6426 extern const bfd_arch_info_type bfd_default_arch_struct;
6428 2.13.2.6 `bfd_set_arch_info'
6429 ............................
6432 void bfd_set_arch_info (bfd *abfd, const bfd_arch_info_type *arg);
6434 Set the architecture info of ABFD to ARG.
6436 2.13.2.7 `bfd_default_set_arch_mach'
6437 ....................................
6440 bfd_boolean bfd_default_set_arch_mach
6441 (bfd *abfd, enum bfd_architecture arch, unsigned long mach);
6443 Set the architecture and machine type in BFD ABFD to ARCH and MACH.

6467 unsigned int bfd_arch_bits_per_byte (bfd *abfd);
6469 Return the number of bits in one of the BFD ABFD's architecture's bytes.
6471 2.13.2.11 `bfd_arch_bits_per_address'
6472 .....................................
6475 unsigned int bfd_arch_bits_per_address (bfd *abfd);
6477 Return the number of bits in one of the BFD ABFD's architecture's
6480 2.13.2.12 `bfd_default_compatible'
6481 ..................................
6484 const bfd_arch_info_type *bfd_default_compatible
6485 (const bfd_arch_info_type *a, const bfd_arch_info_type *b);
6487 The default function for testing for compatibility.
6489 2.13.2.13 `bfd_default_scan'
6490 ............................
6493 bfd_boolean bfd_default_scan
6494 (const struct bfd_arch_info *info, const char *string);
6496 The default function for working out whether this is an architecture
6497 hit and a machine hit.
6499 2.13.2.14 `bfd_get_arch_info'
6500 .............................
6503 const bfd_arch_info_type *bfd_get_arch_info (bfd *abfd);
6505 Return the architecture info struct in ABFD.
6507 2.13.2.15 `bfd_lookup_arch'
6508 ...........................
6511 const bfd_arch_info_type *bfd_lookup_arch
6512 (enum bfd_architecture arch, unsigned long machine);
6514 Look for the architecture info structure which matches the arguments
6515 ARCH and MACHINE. A machine of 0 matches the machine/architecture
6516 structure which marks itself as the default.
6518 2.13.2.16 `bfd_printable_arch_mach'
6519 ...................................
6522 const char *bfd_printable_arch_mach
6523 (enum bfd_architecture arch, unsigned long machine);
6525 Return a printable string representing the architecture and machine
6528 This routine is depreciated.
6530 2.13.2.17 `bfd_octets_per_byte'
6531 ...............................
6534 unsigned int bfd_octets_per_byte (bfd *abfd);
6536 Return the number of octets (8-bit quantities) per target byte (minimum
6537 addressable unit). In most cases, this will be one, but some DSP
6538 targets have 16, 32, or even 48 bits per byte.
6540 2.13.2.18 `bfd_arch_mach_octets_per_byte'
6541 .........................................
6544 unsigned int bfd_arch_mach_octets_per_byte
6545 (enum bfd_architecture arch, unsigned long machine);
6547 See bfd_octets_per_byte.
6549 This routine is provided for those cases where a bfd * is not

6555 2.14 Opening and closing BFDs
6556 =============================
6558 2.14.1 Functions for opening and closing
6559 ----------------------------------------
6561 2.14.1.1 `bfd_fopen'
6562 ....................
6565 bfd *bfd_fopen (const char *filename, const char *target,
6566 const char *mode, int fd);
6568 Open the file FILENAME with the target TARGET. Return a pointer to the
6569 created BFD. If FD is not -1, then `fdopen' is used to open the file;
6570 otherwise, `fopen' is used. MODE is passed directly to `fopen' or
6573 Calls `bfd_find_target', so TARGET is interpreted as by that
6576 The new BFD is marked as cacheable iff FD is -1.
6578 If `NULL' is returned then an error has occured. Possible errors
6579 are `bfd_error_no_memory', `bfd_error_invalid_target' or `system_call'
6582 2.14.1.2 `bfd_openr'
6583 ....................
6586 bfd *bfd_openr (const char *filename, const char *target);
6588 Open the file FILENAME (using `fopen') with the target TARGET. Return
6589 a pointer to the created BFD.
6591 Calls `bfd_find_target', so TARGET is interpreted as by that
6594 If `NULL' is returned then an error has occured. Possible errors
6595 are `bfd_error_no_memory', `bfd_error_invalid_target' or `system_call'
6598 2.14.1.3 `bfd_fdopenr'
6599 ......................
6602 bfd *bfd_fdopenr (const char *filename, const char *target, int fd);
6604 `bfd_fdopenr' is to `bfd_fopenr' much like `fdopen' is to `fopen'. It
6605 opens a BFD on a file already described by the FD supplied.
6607 When the file is later `bfd_close'd, the file descriptor will be
6608 closed. If the caller desires that this file descriptor be cached by
6609 BFD (opened as needed, closed as needed to free descriptors for other
6610 opens), with the supplied FD used as an initial file descriptor (but
6611 subject to closure at any time), call bfd_set_cacheable(bfd, 1) on the
6612 returned BFD. The default is to assume no caching; the file descriptor
6613 will remain open until `bfd_close', and will not be affected by BFD
6614 operations on other files.
6616 Possible errors are `bfd_error_no_memory',
6617 `bfd_error_invalid_target' and `bfd_error_system_call'.
6619 2.14.1.4 `bfd_openstreamr'
6620 ..........................
6623 bfd *bfd_openstreamr (const char *, const char *, void *);
6625 Open a BFD for read access on an existing stdio stream. When the BFD
6626 is passed to `bfd_close', the stream will be closed.
6628 2.14.1.5 `bfd_openr_iovec'
6629 ..........................
6632 bfd *bfd_openr_iovec (const char *filename, const char *target,

6648 created using OPEN, accessed using PREAD and destroyed using CLOSE.
6650 Calls `bfd_find_target', so TARGET is interpreted as by that
6653 Calls OPEN (which can call `bfd_zalloc' and `bfd_get_filename') to
6654 obtain the read-only stream backing the BFD. OPEN either succeeds
6655 returning the non-`NULL' STREAM, or fails returning `NULL' (setting
6658 Calls PREAD to request NBYTES of data from STREAM starting at OFFSET
6659 (e.g., via a call to `bfd_read'). PREAD either succeeds returning the
6660 number of bytes read (which can be less than NBYTES when end-of-file),
6661 or fails returning -1 (setting `bfd_error').
6663 Calls CLOSE when the BFD is later closed using `bfd_close'. CLOSE
6664 either succeeds returning 0, or fails returning -1 (setting
6667 Calls STAT to fill in a stat structure for bfd_stat, bfd_get_size,
6668 and bfd_get_mtime calls. STAT returns 0 on success, or returns -1 on
6669 failure (setting `bfd_error').
6671 If `bfd_openr_iovec' returns `NULL' then an error has occurred.
6672 Possible errors are `bfd_error_no_memory', `bfd_error_invalid_target'
6673 and `bfd_error_system_call'.
6675 2.14.1.6 `bfd_openw'
6676 ....................
6679 bfd *bfd_openw (const char *filename, const char *target);
6681 Create a BFD, associated with file FILENAME, using the file format
6682 TARGET, and return a pointer to it.
6684 Possible errors are `bfd_error_system_call', `bfd_error_no_memory',
6685 `bfd_error_invalid_target'.
6687 2.14.1.7 `bfd_close'
6688 ....................
6691 bfd_boolean bfd_close (bfd *abfd);
6693 Close a BFD. If the BFD was open for writing, then pending operations
6694 are completed and the file written out and closed. If the created file
6695 is executable, then `chmod' is called to mark it as such.
6697 All memory attached to the BFD is released.
6699 The file descriptor associated with the BFD is closed (even if it
6700 was passed in to BFD by `bfd_fdopenr').
6703 `TRUE' is returned if all is ok, otherwise `FALSE'.
6705 2.14.1.8 `bfd_close_all_done'
6706 .............................
6709 bfd_boolean bfd_close_all_done (bfd *);
6711 Close a BFD. Differs from `bfd_close' since it does not complete any
6712 pending operations. This routine would be used if the application had
6713 just used BFD for swapping and didn't want to use any of the writing
6716 If the created file is executable, then `chmod' is called to mark it
6719 All memory attached to the BFD is released.
6722 `TRUE' is returned if all is ok, otherwise `FALSE'.
6724 2.14.1.9 `bfd_create'
6725 .....................
6728 bfd *bfd_create (const char *filename, bfd *templ);
6730 Create a new BFD in the manner of `bfd_openw', but without opening a
6731 file. The new BFD takes the target from the target used by TEMPLATE.
6732 The format is always set to `bfd_object'.
6734 2.14.1.10 `bfd_make_writable'
6735 .............................
6738 bfd_boolean bfd_make_writable (bfd *abfd);
6740 Takes a BFD as created by `bfd_create' and converts it into one like as
6741 returned by `bfd_openw'. It does this by converting the BFD to
6742 BFD_IN_MEMORY. It's assumed that you will call `bfd_make_readable' on
6746 `TRUE' is returned if all is ok, otherwise `FALSE'.
6748 2.14.1.11 `bfd_make_readable'
6749 .............................
6752 bfd_boolean bfd_make_readable (bfd *abfd);
6754 Takes a BFD as created by `bfd_create' and `bfd_make_writable' and
6755 converts it into one like as returned by `bfd_openr'. It does this by
6756 writing the contents out to the memory buffer, then reversing the
6760 `TRUE' is returned if all is ok, otherwise `FALSE'.
6762 2.14.1.12 `bfd_alloc'
6763 .....................
6766 void *bfd_alloc (bfd *abfd, bfd_size_type wanted);
6768 Allocate a block of WANTED bytes of memory attached to `abfd' and
6769 return a pointer to it.
6771 2.14.1.13 `bfd_alloc2'
6772 ......................
6775 void *bfd_alloc2 (bfd *abfd, bfd_size_type nmemb, bfd_size_type size);
6777 Allocate a block of NMEMB elements of SIZE bytes each of memory
6778 attached to `abfd' and return a pointer to it.
6780 2.14.1.14 `bfd_zalloc'
6781 ......................
6784 void *bfd_zalloc (bfd *abfd, bfd_size_type wanted);
6786 Allocate a block of WANTED bytes of zeroed memory attached to `abfd'
6787 and return a pointer to it.
6789 2.14.1.15 `bfd_zalloc2'
6790 .......................
6793 void *bfd_zalloc2 (bfd *abfd, bfd_size_type nmemb, bfd_size_type size);
6795 Allocate a block of NMEMB elements of SIZE bytes each of zeroed memory
6796 attached to `abfd' and return a pointer to it.
6798 2.14.1.16 `bfd_calc_gnu_debuglink_crc32'
6799 ........................................
6802 unsigned long bfd_calc_gnu_debuglink_crc32
6803 (unsigned long crc, const unsigned char *buf, bfd_size_type len);
6805 Computes a CRC value as used in the .gnu_debuglink section. Advances
6806 the previously computed CRC value by computing and adding in the crc32
6807 for LEN bytes of BUF.
6810 Return the updated CRC32 value.
6812 2.14.1.17 `get_debug_link_info'
6813 ...............................
6816 char *get_debug_link_info (bfd *abfd, unsigned long *crc32_out);
6818 fetch the filename and CRC32 value for any separate debuginfo
6819 associated with ABFD. Return NULL if no such info found, otherwise
6820 return filename and update CRC32_OUT.
6822 2.14.1.18 `separate_debug_file_exists'
6823 ......................................
6826 bfd_boolean separate_debug_file_exists
6827 (char *name, unsigned long crc32);
6829 Checks to see if NAME is a file and if its contents match CRC32.
6831 2.14.1.19 `find_separate_debug_file'
6832 ....................................
6835 char *find_separate_debug_file (bfd *abfd);
6837 Searches ABFD for a reference to separate debugging information, scans
6838 various locations in the filesystem, including the file tree rooted at
6839 DEBUG_FILE_DIRECTORY, and returns a filename of such debugging
6840 information if the file is found and has matching CRC32. Returns NULL
6841 if no reference to debugging file exists, or file cannot be found.
6843 2.14.1.20 `bfd_follow_gnu_debuglink'
6844 ....................................
6847 char *bfd_follow_gnu_debuglink (bfd *abfd, const char *dir);
6849 Takes a BFD and searches it for a .gnu_debuglink section. If this
6850 section is found, it examines the section for the name and checksum of
6851 a '.debug' file containing auxiliary debugging information. It then
6852 searches the filesystem for this .debug file in some standard
6853 locations, including the directory tree rooted at DIR, and if found
6854 returns the full filename.
6856 If DIR is NULL, it will search a default path configured into libbfd
6857 at build time. [XXX this feature is not currently implemented].
6860 `NULL' on any errors or failure to locate the .debug file, otherwise a
6861 pointer to a heap-allocated string containing the filename. The caller
6862 is responsible for freeing this string.
6864 2.14.1.21 `bfd_create_gnu_debuglink_section'
6865 ............................................
6868 struct bfd_section *bfd_create_gnu_debuglink_section
6869 (bfd *abfd, const char *filename);
6871 Takes a BFD and adds a .gnu_debuglink section to it. The section is
6872 sized to be big enough to contain a link to the specified FILENAME.
6875 A pointer to the new section is returned if all is ok. Otherwise
6876 `NULL' is returned and bfd_error is set.
6878 2.14.1.22 `bfd_fill_in_gnu_debuglink_section'
6879 .............................................
6882 bfd_boolean bfd_fill_in_gnu_debuglink_section
6883 (bfd *abfd, struct bfd_section *sect, const char *filename);
6885 Takes a BFD and containing a .gnu_debuglink section SECT and fills in
6886 the contents of the section to contain a link to the specified
6887 FILENAME. The filename should be relative to the current directory.
6890 `TRUE' is returned if all is ok. Otherwise `FALSE' is returned and

6897 ===========================
6899 2.15.1 Internal functions
6900 -------------------------
6903 These routines are used within BFD. They are not intended for export,
6904 but are documented here for completeness.
6906 2.15.1.1 `bfd_write_bigendian_4byte_int'
6907 ........................................
6910 bfd_boolean bfd_write_bigendian_4byte_int (bfd *, unsigned int);
6912 Write a 4 byte integer I to the output BFD ABFD, in big endian order
6913 regardless of what else is going on. This is useful in archives.
6915 2.15.1.2 `bfd_put_size'
6916 .......................
6918 2.15.1.3 `bfd_get_size'
6919 .......................
6922 These macros as used for reading and writing raw data in sections; each
6923 access (except for bytes) is vectored through the target format of the
6924 BFD and mangled accordingly. The mangling performs any necessary endian
6925 translations and removes alignment restrictions. Note that types
6926 accepted and returned by these macros are identical so they can be
6927 swapped around in macros--for example, `libaout.h' defines `GET_WORD'
6928 to either `bfd_get_32' or `bfd_get_64'.
6930 In the put routines, VAL must be a `bfd_vma'. If we are on a system
6931 without prototypes, the caller is responsible for making sure that is
6932 true, with a cast if necessary. We don't cast them in the macro
6933 definitions because that would prevent `lint' or `gcc -Wall' from
6934 detecting sins such as passing a pointer. To detect calling these with
6935 less than a `bfd_vma', use `gcc -Wconversion' on a host with 64 bit

7067 File: bfd.info, Node: File Caching, Next: Linker Functions, Prev: Internal, Up: BFD front end
7072 The file caching mechanism is embedded within BFD and allows the
7073 application to open as many BFDs as it wants without regard to the
7074 underlying operating system's file descriptor limit (often as low as 20
7075 open files). The module in `cache.c' maintains a least recently used
7076 list of `BFD_CACHE_MAX_OPEN' files, and exports the name
7077 `bfd_cache_lookup', which runs around and makes sure that the required
7078 BFD is open. If not, then it chooses a file to close, closes it and
7079 opens the one wanted, returning its file handle.

7133 2.17 Linker Functions
7134 =====================
7136 The linker uses three special entry points in the BFD target vector.
7137 It is not necessary to write special routines for these entry points
7138 when creating a new BFD back end, since generic versions are provided.
7139 However, writing them can speed up linking and make it use
7140 significantly less runtime memory.
7142 The first routine creates a hash table used by the other routines.
7143 The second routine adds the symbols from an object file to the hash
7144 table. The third routine takes all the object files and links them
7145 together to create the output file. These routines are designed so
7146 that the linker proper does not need to know anything about the symbols
7147 in the object files that it is linking. The linker merely arranges the
7148 sections as directed by the linker script and lets BFD handle the
7149 details of symbols and relocs.
7151 The second routine and third routines are passed a pointer to a
7152 `struct bfd_link_info' structure (defined in `bfdlink.h') which holds
7153 information relevant to the link, including the linker hash table
7154 (which was created by the first routine) and a set of callback
7155 functions to the linker proper.
7157 The generic linker routines are in `linker.c', and use the header
7158 file `genlink.h'. As of this writing, the only back ends which have
7159 implemented versions of these routines are a.out (in `aoutx.h') and
7160 ECOFF (in `ecoff.c'). The a.out routines are used as examples
7161 throughout this section.

7172 2.17.1 Creating a linker hash table
7173 -----------------------------------
7175 The linker routines must create a hash table, which must be derived
7176 from `struct bfd_link_hash_table' described in `bfdlink.c'. *Note Hash
7177 Tables::, for information on how to create a derived hash table. This
7178 entry point is called using the target vector of the linker output file.
7180 The `_bfd_link_hash_table_create' entry point must allocate and
7181 initialize an instance of the desired hash table. If the back end does
7182 not require any additional information to be stored with the entries in
7183 the hash table, the entry point may simply create a `struct
7184 bfd_link_hash_table'. Most likely, however, some additional
7185 information will be needed.
7187 For example, with each entry in the hash table the a.out linker
7188 keeps the index the symbol has in the final output file (this index
7189 number is used so that when doing a relocatable link the symbol index
7190 used in the output file can be quickly filled in when copying over a
7191 reloc). The a.out linker code defines the required structures and
7192 functions for a hash table derived from `struct bfd_link_hash_table'.
7193 The a.out linker hash table is created by the function
7194 `NAME(aout,link_hash_table_create)'; it simply allocates space for the
7195 hash table, initializes it, and returns a pointer to it.
7197 When writing the linker routines for a new back end, you will
7198 generally not know exactly which fields will be required until you have
7199 finished. You should simply create a new hash table which defines no
7200 additional fields, and then simply add fields as they become necessary.

7205 2.17.2 Adding symbols to the hash table
7206 ---------------------------------------
7208 The linker proper will call the `_bfd_link_add_symbols' entry point for
7209 each object file or archive which is to be linked (typically these are
7210 the files named on the command line, but some may also come from the
7211 linker script). The entry point is responsible for examining the file.
7212 For an object file, BFD must add any relevant symbol information to
7213 the hash table. For an archive, BFD must determine which elements of
7214 the archive should be used and adding them to the link.
7216 The a.out version of this entry point is

7228 2.17.2.1 Differing file formats
7229 ...............................
7231 Normally all the files involved in a link will be of the same format,
7232 but it is also possible to link together different format object files,
7233 and the back end must support that. The `_bfd_link_add_symbols' entry
7234 point is called via the target vector of the file to be added. This
7235 has an important consequence: the function may not assume that the hash
7236 table is the type created by the corresponding
7237 `_bfd_link_hash_table_create' vector. All the `_bfd_link_add_symbols'
7238 function can assume about the hash table is that it is derived from
7239 `struct bfd_link_hash_table'.
7241 Sometimes the `_bfd_link_add_symbols' function must store some
7242 information in the hash table entry to be used by the `_bfd_final_link'
7243 function. In such a case the output bfd xvec must be checked to make
7244 sure that the hash table was created by an object file of the same
7247 The `_bfd_final_link' routine must be prepared to handle a hash
7248 entry without any extra information added by the
7249 `_bfd_link_add_symbols' function. A hash entry without extra
7250 information will also occur when the linker script directs the linker
7251 to create a symbol. Note that, regardless of how a hash table entry is
7252 added, all the fields will be initialized to some sort of null value by
7253 the hash table entry initialization function.
7255 See `ecoff_link_add_externals' for an example of how to check the
7256 output bfd before saving information (in this case, the ECOFF external
7257 symbol debugging information) in a hash table entry.

7262 2.17.2.2 Adding symbols from an object file
7263 ...........................................
7265 When the `_bfd_link_add_symbols' routine is passed an object file, it
7266 must add all externally visible symbols in that object file to the hash
7267 table. The actual work of adding the symbol to the hash table is
7268 normally handled by the function `_bfd_generic_link_add_one_symbol'.
7269 The `_bfd_link_add_symbols' routine is responsible for reading all the
7270 symbols from the object file and passing the correct information to
7271 `_bfd_generic_link_add_one_symbol'.
7273 The `_bfd_link_add_symbols' routine should not use
7274 `bfd_canonicalize_symtab' to read the symbols. The point of providing
7275 this routine is to avoid the overhead of converting the symbols into
7276 generic `asymbol' structures.
7278 `_bfd_generic_link_add_one_symbol' handles the details of combining
7279 common symbols, warning about multiple definitions, and so forth. It
7280 takes arguments which describe the symbol to add, notably symbol flags,
7281 a section, and an offset. The symbol flags include such things as
7282 `BSF_WEAK' or `BSF_INDIRECT'. The section is a section in the object
7283 file, or something like `bfd_und_section_ptr' for an undefined symbol
7284 or `bfd_com_section_ptr' for a common symbol.
7286 If the `_bfd_final_link' routine is also going to need to read the
7287 symbol information, the `_bfd_link_add_symbols' routine should save it
7288 somewhere attached to the object file BFD. However, the information
7289 should only be saved if the `keep_memory' field of the `info' argument
7290 is TRUE, so that the `-no-keep-memory' linker switch is effective.
7292 The a.out function which adds symbols from an object file is
7293 `aout_link_add_object_symbols', and most of the interesting work is in
7294 `aout_link_add_symbols'. The latter saves pointers to the hash tables
7295 entries created by `_bfd_generic_link_add_one_symbol' indexed by symbol
7296 number, so that the `_bfd_final_link' routine does not have to call the
7297 hash table lookup routine to locate the entry.
7300 File: bfd.info, Node: Adding symbols from an archive, Prev: Adding symbols from an object file, Up: Adding Symbols to the Hash Table
7302 2.17.2.3 Adding symbols from an archive
7303 .......................................
7305 When the `_bfd_link_add_symbols' routine is passed an archive, it must
7306 look through the symbols defined by the archive and decide which
7307 elements of the archive should be included in the link. For each such
7308 element it must call the `add_archive_element' linker callback, and it
7309 must add the symbols from the object file to the linker hash table.
7311 In most cases the work of looking through the symbols in the archive
7312 should be done by the `_bfd_generic_link_add_archive_symbols' function.
7313 This function builds a hash table from the archive symbol table and
7314 looks through the list of undefined symbols to see which elements
7315 should be included. `_bfd_generic_link_add_archive_symbols' is passed
7316 a function to call to make the final decision about adding an archive
7317 element to the link and to do the actual work of adding the symbols to
7318 the linker hash table.
7320 The function passed to `_bfd_generic_link_add_archive_symbols' must
7321 read the symbols of the archive element and decide whether the archive
7322 element should be included in the link. If the element is to be
7323 included, the `add_archive_element' linker callback routine must be
7324 called with the element as an argument, and the elements symbols must
7325 be added to the linker hash table just as though the element had itself
7326 been passed to the `_bfd_link_add_symbols' function.
7328 When the a.out `_bfd_link_add_symbols' function receives an archive,
7329 it calls `_bfd_generic_link_add_archive_symbols' passing
7330 `aout_link_check_archive_element' as the function argument.
7331 `aout_link_check_archive_element' calls `aout_link_check_ar_symbols'.
7332 If the latter decides to add the element (an element is only added if
7333 it provides a real, non-common, definition for a previously undefined
7334 or common symbol) it calls the `add_archive_element' callback and then
7335 `aout_link_check_archive_element' calls `aout_link_add_symbols' to
7336 actually add the symbols to the linker hash table.
7338 The ECOFF back end is unusual in that it does not normally call
7339 `_bfd_generic_link_add_archive_symbols', because ECOFF archives already
7340 contain a hash table of symbols. The ECOFF back end searches the
7341 archive itself to avoid the overhead of creating a new hash table.

7346 2.17.3 Performing the final link
7347 --------------------------------
7349 When all the input files have been processed, the linker calls the
7350 `_bfd_final_link' entry point of the output BFD. This routine is
7351 responsible for producing the final output file, which has several
7352 aspects. It must relocate the contents of the input sections and copy
7353 the data into the output sections. It must build an output symbol
7354 table including any local symbols from the input files and the global
7355 symbols from the hash table. When producing relocatable output, it must
7356 modify the input relocs and write them into the output file. There may
7357 also be object format dependent work to be done.
7359 The linker will also call the `write_object_contents' entry point
7360 when the BFD is closed. The two entry points must work together in
7361 order to produce the correct output file.
7363 The details of how this works are inevitably dependent upon the
7364 specific object file format. The a.out `_bfd_final_link' routine is
7365 `NAME(aout,final_link)'.

7377 ...........................................
7379 Before the linker calls the `_bfd_final_link' entry point, it sets up
7380 some data structures for the function to use.
7382 The `input_bfds' field of the `bfd_link_info' structure will point
7383 to a list of all the input files included in the link. These files are
7384 linked through the `link_next' field of the `bfd' structure.
7386 Each section in the output file will have a list of `link_order'
7387 structures attached to the `map_head.link_order' field (the
7388 `link_order' structure is defined in `bfdlink.h'). These structures
7389 describe how to create the contents of the output section in terms of
7390 the contents of various input sections, fill constants, and,
7391 eventually, other types of information. They also describe relocs that
7392 must be created by the BFD backend, but do not correspond to any input
7393 file; this is used to support -Ur, which builds constructors while
7394 generating a relocatable object file.

7399 2.17.3.2 Relocating the section contents
7400 ........................................
7402 The `_bfd_final_link' function should look through the `link_order'
7403 structures attached to each section of the output file. Each
7404 `link_order' structure should either be handled specially, or it should
7405 be passed to the function `_bfd_default_link_order' which will do the
7406 right thing (`_bfd_default_link_order' is defined in `linker.c').
7408 For efficiency, a `link_order' of type `bfd_indirect_link_order'
7409 whose associated section belongs to a BFD of the same format as the
7410 output BFD must be handled specially. This type of `link_order'
7411 describes part of an output section in terms of a section belonging to
7412 one of the input files. The `_bfd_final_link' function should read the
7413 contents of the section and any associated relocs, apply the relocs to
7414 the section contents, and write out the modified section contents. If
7415 performing a relocatable link, the relocs themselves must also be
7416 modified and written out.
7418 The functions `_bfd_relocate_contents' and
7419 `_bfd_final_link_relocate' provide some general support for performing
7420 the actual relocations, notably overflow checking. Their arguments
7421 include information about the symbol the relocation is against and a
7422 `reloc_howto_type' argument which describes the relocation to perform.
7423 These functions are defined in `reloc.c'.
7425 The a.out function which handles reading, relocating, and writing
7426 section contents is `aout_link_input_section'. The actual relocation
7427 is done in `aout_link_input_section_std' and
7428 `aout_link_input_section_ext'.

7433 2.17.3.3 Writing the symbol table
7434 .................................
7436 The `_bfd_final_link' function must gather all the symbols in the input
7437 files and write them out. It must also write out all the symbols in
7438 the global hash table. This must be controlled by the `strip' and
7439 `discard' fields of the `bfd_link_info' structure.
7441 The local symbols of the input files will not have been entered into
7442 the linker hash table. The `_bfd_final_link' routine must consider
7443 each input file and include the symbols in the output file. It may be
7444 convenient to do this when looking through the `link_order' structures,
7445 or it may be done by stepping through the `input_bfds' list.
7447 The `_bfd_final_link' routine must also traverse the global hash
7448 table to gather all the externally visible symbols. It is possible
7449 that most of the externally visible symbols may be written out when
7450 considering the symbols of each input file, but it is still necessary
7451 to traverse the hash table since the linker script may have defined
7452 some symbols that are not in any of the input files.
7454 The `strip' field of the `bfd_link_info' structure controls which
7455 symbols are written out. The possible values are listed in
7456 `bfdlink.h'. If the value is `strip_some', then the `keep_hash' field
7457 of the `bfd_link_info' structure is a hash table of symbols to keep;
7458 each symbol should be looked up in this hash table, and only symbols
7459 which are present should be included in the output file.
7461 If the `strip' field of the `bfd_link_info' structure permits local
7462 symbols to be written out, the `discard' field is used to further
7463 controls which local symbols are included in the output file. If the
7464 value is `discard_l', then all local symbols which begin with a certain
7465 prefix are discarded; this is controlled by the
7466 `bfd_is_local_label_name' entry point.
7468 The a.out backend handles symbols by calling
7469 `aout_link_write_symbols' on each input BFD and then traversing the
7470 global hash table with the function `aout_link_write_other_symbol'. It
7471 builds a string table while writing out the symbols, which is written
7472 to the output file at the end of `NAME(aout,final_link)'.

7503 BFD provides a simple set of hash table functions. Routines are
7504 provided to initialize a hash table, to free a hash table, to look up a
7505 string in a hash table and optionally create an entry for it, and to
7506 traverse a hash table. There is currently no routine to delete an
7507 string from a hash table.
7509 The basic hash table does not permit any data to be stored with a
7510 string. However, a hash table is designed to present a base class from
7511 which other types of hash tables may be derived. These derived types
7512 may store additional information with the string. Hash tables were
7513 implemented in this way, rather than simply providing a data pointer in
7514 a hash table entry, because they were designed for use by the linker
7515 back ends. The linker may create thousands of hash table entries, and
7516 the overhead of allocating private data and storing and following
7517 pointers becomes noticeable.
7519 The basic hash table code is in `hash.c'.

7531 2.18.1 Creating and freeing a hash table
7532 ----------------------------------------
7534 To create a hash table, create an instance of a `struct bfd_hash_table'
7535 (defined in `bfd.h') and call `bfd_hash_table_init' (if you know
7536 approximately how many entries you will need, the function
7537 `bfd_hash_table_init_n', which takes a SIZE argument, may be used).
7538 `bfd_hash_table_init' returns `FALSE' if some sort of error occurs.
7540 The function `bfd_hash_table_init' take as an argument a function to
7541 use to create new entries. For a basic hash table, use the function
7542 `bfd_hash_newfunc'. *Note Deriving a New Hash Table Type::, for why
7543 you would want to use a different value for this argument.
7545 `bfd_hash_table_init' will create an objalloc which will be used to
7546 allocate new entries. You may allocate memory on this objalloc using
7547 `bfd_hash_allocate'.
7549 Use `bfd_hash_table_free' to free up all the memory that has been
7550 allocated for a hash table. This will not free up the `struct
7551 bfd_hash_table' itself, which you must provide.
7553 Use `bfd_hash_set_default_size' to set the default size of hash

7559 2.18.2 Looking up or entering a string
7560 --------------------------------------
7562 The function `bfd_hash_lookup' is used both to look up a string in the
7563 hash table and to create a new entry.
7565 If the CREATE argument is `FALSE', `bfd_hash_lookup' will look up a
7566 string. If the string is found, it will returns a pointer to a `struct
7567 bfd_hash_entry'. If the string is not found in the table
7568 `bfd_hash_lookup' will return `NULL'. You should not modify any of the
7569 fields in the returns `struct bfd_hash_entry'.
7571 If the CREATE argument is `TRUE', the string will be entered into
7572 the hash table if it is not already there. Either way a pointer to a
7573 `struct bfd_hash_entry' will be returned, either to the existing
7574 structure or to a newly created one. In this case, a `NULL' return
7575 means that an error occurred.
7577 If the CREATE argument is `TRUE', and a new entry is created, the
7578 COPY argument is used to decide whether to copy the string onto the
7579 hash table objalloc or not. If COPY is passed as `FALSE', you must be
7580 careful not to deallocate or modify the string as long as the hash table

7586 2.18.3 Traversing a hash table
7587 ------------------------------
7589 The function `bfd_hash_traverse' may be used to traverse a hash table,
7590 calling a function on each element. The traversal is done in a random
7593 `bfd_hash_traverse' takes as arguments a function and a generic
7594 `void *' pointer. The function is called with a hash table entry (a
7595 `struct bfd_hash_entry *') and the generic pointer passed to
7596 `bfd_hash_traverse'. The function must return a `boolean' value, which
7597 indicates whether to continue traversing the hash table. If the
7598 function returns `FALSE', `bfd_hash_traverse' will stop the traversal
7599 and return immediately.

7604 2.18.4 Deriving a new hash table type
7605 -------------------------------------
7607 Many uses of hash tables want to store additional information which
7608 each entry in the hash table. Some also find it convenient to store
7609 additional information with the hash table itself. This may be done
7610 using a derived hash table.
7612 Since C is not an object oriented language, creating a derived hash
7613 table requires sticking together some boilerplate routines with a few
7614 differences specific to the type of hash table you want to create.
7616 An example of a derived hash table is the linker hash table. The
7617 structures for this are defined in `bfdlink.h'. The functions are in
7620 You may also derive a hash table from an already derived hash table.
7621 For example, the a.out linker backend code uses a hash table derived
7622 from the linker hash table.

7633 2.18.4.1 Define the derived structures
7634 ......................................
7636 You must define a structure for an entry in the hash table, and a
7637 structure for the hash table itself.
7639 The first field in the structure for an entry in the hash table must
7640 be of the type used for an entry in the hash table you are deriving
7641 from. If you are deriving from a basic hash table this is `struct
7642 bfd_hash_entry', which is defined in `bfd.h'. The first field in the
7643 structure for the hash table itself must be of the type of the hash
7644 table you are deriving from itself. If you are deriving from a basic
7645 hash table, this is `struct bfd_hash_table'.
7647 For example, the linker hash table defines `struct
7648 bfd_link_hash_entry' (in `bfdlink.h'). The first field, `root', is of
7649 type `struct bfd_hash_entry'. Similarly, the first field in `struct
7650 bfd_link_hash_table', `table', is of type `struct bfd_hash_table'.

7655 2.18.4.2 Write the derived creation routine
7656 ...........................................
7658 You must write a routine which will create and initialize an entry in
7659 the hash table. This routine is passed as the function argument to
7660 `bfd_hash_table_init'.
7662 In order to permit other hash tables to be derived from the hash
7663 table you are creating, this routine must be written in a standard way.
7665 The first argument to the creation routine is a pointer to a hash
7666 table entry. This may be `NULL', in which case the routine should
7667 allocate the right amount of space. Otherwise the space has already
7668 been allocated by a hash table type derived from this one.
7670 After allocating space, the creation routine must call the creation
7671 routine of the hash table type it is derived from, passing in a pointer
7672 to the space it just allocated. This will initialize any fields used
7673 by the base hash table.
7675 Finally the creation routine must initialize any local fields for
7676 the new hash table type.
7678 Here is a boilerplate example of a creation routine. FUNCTION_NAME
7679 is the name of the routine. ENTRY_TYPE is the type of an entry in the
7680 hash table you are creating. BASE_NEWFUNC is the name of the creation
7681 routine of the hash table type your hash table is derived from.
7683 struct bfd_hash_entry *
7684 FUNCTION_NAME (struct bfd_hash_entry *entry,
7685 struct bfd_hash_table *table,
7688 struct ENTRY_TYPE *ret = (ENTRY_TYPE *) entry;
7690 /* Allocate the structure if it has not already been allocated by a
7694 ret = bfd_hash_allocate (table, sizeof (* ret));
7699 /* Call the allocation method of the base class. */
7700 ret = ((ENTRY_TYPE *)
7701 BASE_NEWFUNC ((struct bfd_hash_entry *) ret, table, string));
7703 /* Initialize the local fields here. */
7705 return (struct bfd_hash_entry *) ret;
7708 The creation routine for the linker hash table, which is in `linker.c',
7709 looks just like this example. FUNCTION_NAME is
7710 `_bfd_link_hash_newfunc'. ENTRY_TYPE is `struct bfd_link_hash_entry'.
7711 BASE_NEWFUNC is `bfd_hash_newfunc', the creation routine for a basic
7714 `_bfd_link_hash_newfunc' also initializes the local fields in a
7715 linker hash table entry: `type', `written' and `next'.

7720 2.18.4.3 Write other derived routines
7721 .....................................
7723 You will want to write other routines for your new hash table, as well.
7725 You will want an initialization routine which calls the
7726 initialization routine of the hash table you are deriving from and
7727 initializes any other local fields. For the linker hash table, this is
7728 `_bfd_link_hash_table_init' in `linker.c'.
7730 You will want a lookup routine which calls the lookup routine of the
7731 hash table you are deriving from and casts the result. The linker hash
7732 table uses `bfd_link_hash_lookup' in `linker.c' (this actually takes an
7733 additional argument which it uses to decide how to return the looked up
7736 You may want a traversal routine. This should just call the
7737 traversal routine of the hash table you are deriving from with
7738 appropriate casts. The linker hash table uses `bfd_link_hash_traverse'
7741 These routines may simply be defined as macros. For example, the
7742 a.out backend linker hash table, which is derived from the linker hash
7743 table, uses macros for the lookup and traversal routines. These are
7744 `aout_link_hash_lookup' and `aout_link_hash_traverse' in aoutx.h.

7763 3.1 What to Put Where
7764 =====================
7766 All of BFD lives in one directory.
7769 File: bfd.info, Node: aout, Next: coff, Prev: What to Put Where, Up: BFD back ends
7775 BFD supports a number of different flavours of a.out format, though the
7776 major differences are only the sizes of the structures on disk, and the
7777 shape of the relocation information.
7779 The support is split into a basic support file `aoutx.h' and other
7780 files which derive functions from the base. One derivation file is
7781 `aoutf1.h' (for a.out flavour 1), and adds to the basic a.out functions
7782 support for sun3, sun4, 386 and 29k a.out files, to create a target
7783 jump vector for a specific target.
7785 This information is further split out into more specific files for
7786 each machine, including `sunos.c' for sun3 and sun4, `newsos3.c' for
7787 the Sony NEWS, and `demo64.c' for a demonstration of a 64 bit a.out
7790 The base file `aoutx.h' defines general mechanisms for reading and
7791 writing records to and from disk and various other methods which BFD
7792 requires. It is included by `aout32.c' and `aout64.c' to form the names
7793 `aout_32_swap_exec_header_in', `aout_64_swap_exec_header_in', etc.
7795 As an example, this is what goes on to make the back end for a sun4,
7798 #define ARCH_SIZE 32
7801 Which exports names:
7804 aout_32_canonicalize_reloc
7805 aout_32_find_nearest_line
7807 aout_32_get_reloc_upper_bound
7812 #define TARGET_NAME "a.out-sunos-big"
7813 #define VECNAME sunos_big_vec
7816 requires all the names from `aout32.c', and produces the jump vector
7820 The file `host-aout.c' is a special case. It is for a large set of
7821 hosts that use "more or less standard" a.out files, and for which
7822 cross-debugging is not interesting. It uses the standard 32-bit a.out
7823 support routines, but determines the file offsets and addresses of the
7824 text, data, and BSS sections, the machine architecture and machine
7825 type, and the entry point address, in a host-dependent manner. Once
7826 these values have been determined, generic code is used to handle the
7829 When porting it to run on a new system, you must supply:
7833 HOST_MACHINE_ARCH (optional)
7834 HOST_MACHINE_MACHINE (optional)
7835 HOST_TEXT_START_ADDR
7838 in the file `../include/sys/h-XXX.h' (for your host). These values,
7839 plus the structures and macros defined in `a.out.h' on your host
7840 system, will produce a BFD target that will access ordinary a.out files
7841 on your host. To configure a new machine to use `host-aout.c', specify:
7843 TDEFAULTS = -DDEFAULT_VECTOR=host_aout_big_vec
7844 TDEPFILES= host-aout.o trad-core.o
7846 in the `config/XXX.mt' file, and modify `configure.in' to use the
7847 `XXX.mt' file (by setting "`bfd_target=XXX'") when your configuration
7854 The file `aoutx.h' provides for both the _standard_ and _extended_
7855 forms of a.out relocation records.
7857 The standard records contain only an address, a symbol index, and a
7858 type field. The extended records (used on 29ks and sparcs) also have a
7859 full integer for an addend.
7861 3.2.2 Internal entry points
7862 ---------------------------
7865 `aoutx.h' exports several routines for accessing the contents of an
7866 a.out file, which are gathered and exported in turn by various format
7867 specific files (eg sunos.c).
7869 3.2.2.1 `aout_SIZE_swap_exec_header_in'
7870 .......................................
7873 void aout_SIZE_swap_exec_header_in,
7875 struct external_exec *bytes,
7876 struct internal_exec *execp);
7878 Swap the information in an executable header RAW_BYTES taken from a raw
7879 byte stream memory image into the internal exec header structure EXECP.
7881 3.2.2.2 `aout_SIZE_swap_exec_header_out'
7882 ........................................
7885 void aout_SIZE_swap_exec_header_out
7887 struct internal_exec *execp,
7888 struct external_exec *raw_bytes);
7890 Swap the information in an internal exec header structure EXECP into
7891 the buffer RAW_BYTES ready for writing to disk.
7893 3.2.2.3 `aout_SIZE_some_aout_object_p'
7894 ......................................
7897 const bfd_target *aout_SIZE_some_aout_object_p
7899 struct internal_exec *execp,
7900 const bfd_target *(*callback_to_real_object_p) (bfd *));
7902 Some a.out variant thinks that the file open in ABFD checking is an
7903 a.out file. Do some more checking, and set up for access if it really
7904 is. Call back to the calling environment's "finish up" function just
7905 before returning, to handle any last-minute setup.
7907 3.2.2.4 `aout_SIZE_mkobject'
7908 ............................
7911 bfd_boolean aout_SIZE_mkobject, (bfd *abfd);
7913 Initialize BFD ABFD for use with a.out files.
7915 3.2.2.5 `aout_SIZE_machine_type'
7916 ................................
7919 enum machine_type aout_SIZE_machine_type
7920 (enum bfd_architecture arch,
7921 unsigned long machine,
7922 bfd_boolean *unknown);
7924 Keep track of machine architecture and machine type for a.out's. Return
7925 the `machine_type' for a particular architecture and machine, or
7926 `M_UNKNOWN' if that exact architecture and machine can't be represented
7929 If the architecture is understood, machine type 0 (default) is
7932 3.2.2.6 `aout_SIZE_set_arch_mach'
7933 .................................
7936 bfd_boolean aout_SIZE_set_arch_mach,
7938 enum bfd_architecture arch,
7939 unsigned long machine);
7941 Set the architecture and the machine of the BFD ABFD to the values ARCH
7942 and MACHINE. Verify that ABFD's format can support the architecture
7945 3.2.2.7 `aout_SIZE_new_section_hook'
7946 ....................................
7949 bfd_boolean aout_SIZE_new_section_hook,
7953 Called by the BFD in response to a `bfd_make_section' request.
7956 File: bfd.info, Node: coff, Next: elf, Prev: aout, Up: BFD back ends
7961 BFD supports a number of different flavours of coff format. The major
7962 differences between formats are the sizes and alignments of fields in
7963 structures on disk, and the occasional extra field.
7965 Coff in all its varieties is implemented with a few common files and
7966 a number of implementation specific files. For example, The 88k bcs
7967 coff format is implemented in the file `coff-m88k.c'. This file
7968 `#include's `coff/m88k.h' which defines the external structure of the
7969 coff format for the 88k, and `coff/internal.h' which defines the
7970 internal structure. `coff-m88k.c' also defines the relocations used by
7971 the 88k format *Note Relocations::.
7973 The Intel i960 processor version of coff is implemented in
7974 `coff-i960.c'. This file has the same structure as `coff-m88k.c',
7975 except that it includes `coff/i960.h' rather than `coff-m88k.h'.
7977 3.3.1 Porting to a new version of coff
7978 --------------------------------------
7980 The recommended method is to select from the existing implementations
7981 the version of coff which is most like the one you want to use. For
7982 example, we'll say that i386 coff is the one you select, and that your
7983 coff flavour is called foo. Copy `i386coff.c' to `foocoff.c', copy
7984 `../include/coff/i386.h' to `../include/coff/foo.h', and add the lines
7985 to `targets.c' and `Makefile.in' so that your new back end is used.
7986 Alter the shapes of the structures in `../include/coff/foo.h' so that
7987 they match what you need. You will probably also have to add `#ifdef's
7988 to the code in `coff/internal.h' and `coffcode.h' if your version of
7991 You can verify that your new BFD backend works quite simply by
7992 building `objdump' from the `binutils' directory, and making sure that
7993 its version of what's going on and your host system's idea (assuming it
7994 has the pretty standard coff dump utility, usually called `att-dump' or
7995 just `dump') are the same. Then clean up your code, and send what
7996 you've done to Cygnus. Then your stuff will be in the next release, and
7997 you won't have to keep integrating it.
7999 3.3.2 How the coff backend works
8000 --------------------------------
8005 The Coff backend is split into generic routines that are applicable to
8006 any Coff target and routines that are specific to a particular target.
8007 The target-specific routines are further split into ones which are
8008 basically the same for all Coff targets except that they use the
8009 external symbol format or use different values for certain constants.
8011 The generic routines are in `coffgen.c'. These routines work for
8012 any Coff target. They use some hooks into the target specific code;
8013 the hooks are in a `bfd_coff_backend_data' structure, one of which
8014 exists for each target.
8016 The essentially similar target-specific routines are in
8017 `coffcode.h'. This header file includes executable C code. The
8018 various Coff targets first include the appropriate Coff header file,
8019 make any special defines that are needed, and then include `coffcode.h'.
8021 Some of the Coff targets then also have additional routines in the
8022 target source file itself.
8024 For example, `coff-i960.c' includes `coff/internal.h' and
8025 `coff/i960.h'. It then defines a few constants, such as `I960', and
8026 includes `coffcode.h'. Since the i960 has complex relocation types,
8027 `coff-i960.c' also includes some code to manipulate the i960 relocs.
8028 This code is not in `coffcode.h' because it would not be used by any
8031 3.3.2.2 Bit twiddling
8032 .....................
8034 Each flavour of coff supported in BFD has its own header file
8035 describing the external layout of the structures. There is also an
8036 internal description of the coff layout, in `coff/internal.h'. A major
8037 function of the coff backend is swapping the bytes and twiddling the
8038 bits to translate the external form of the structures into the normal
8039 internal form. This is all performed in the `bfd_swap'_thing_direction
8040 routines. Some elements are different sizes between different versions
8041 of coff; it is the duty of the coff version specific include file to
8042 override the definitions of various packing routines in `coffcode.h'.
8043 E.g., the size of line number entry in coff is sometimes 16 bits, and
8044 sometimes 32 bits. `#define'ing `PUT_LNSZ_LNNO' and `GET_LNSZ_LNNO'
8045 will select the correct one. No doubt, some day someone will find a
8046 version of coff which has a varying field size not catered to at the
8047 moment. To port BFD, that person will have to add more `#defines'.
8048 Three of the bit twiddling routines are exported to `gdb';
8049 `coff_swap_aux_in', `coff_swap_sym_in' and `coff_swap_lineno_in'. `GDB'
8050 reads the symbol table on its own, but uses BFD to fix things up. More
8051 of the bit twiddlers are exported for `gas'; `coff_swap_aux_out',
8052 `coff_swap_sym_out', `coff_swap_lineno_out', `coff_swap_reloc_out',
8053 `coff_swap_filehdr_out', `coff_swap_aouthdr_out',
8054 `coff_swap_scnhdr_out'. `Gas' currently keeps track of all the symbol
8055 table and reloc drudgery itself, thereby saving the internal BFD
8056 overhead, but uses BFD to swap things on the way out, making cross
8057 ports much safer. Doing so also allows BFD (and thus the linker) to
8058 use the same header files as `gas', which makes one avenue to disaster
8061 3.3.2.3 Symbol reading
8062 ......................
8064 The simple canonical form for symbols used by BFD is not rich enough to
8065 keep all the information available in a coff symbol table. The back end
8066 gets around this problem by keeping the original symbol table around,
8067 "behind the scenes".
8069 When a symbol table is requested (through a call to
8070 `bfd_canonicalize_symtab'), a request gets through to
8071 `coff_get_normalized_symtab'. This reads the symbol table from the coff
8072 file and swaps all the structures inside into the internal form. It
8073 also fixes up all the pointers in the table (represented in the file by
8074 offsets from the first symbol in the table) into physical pointers to
8075 elements in the new internal table. This involves some work since the
8076 meanings of fields change depending upon context: a field that is a
8077 pointer to another structure in the symbol table at one moment may be
8078 the size in bytes of a structure at the next. Another pass is made
8079 over the table. All symbols which mark file names (`C_FILE' symbols)
8080 are modified so that the internal string points to the value in the
8081 auxent (the real filename) rather than the normal text associated with
8082 the symbol (`".file"').
8084 At this time the symbol names are moved around. Coff stores all
8085 symbols less than nine characters long physically within the symbol
8086 table; longer strings are kept at the end of the file in the string
8087 table. This pass moves all strings into memory and replaces them with
8088 pointers to the strings.
8090 The symbol table is massaged once again, this time to create the
8091 canonical table used by the BFD application. Each symbol is inspected
8092 in turn, and a decision made (using the `sclass' field) about the
8093 various flags to set in the `asymbol'. *Note Symbols::. The generated
8094 canonical table shares strings with the hidden internal symbol table.
8096 Any linenumbers are read from the coff file too, and attached to the
8097 symbols which own the functions the linenumbers belong to.
8099 3.3.2.4 Symbol writing
8100 ......................
8102 Writing a symbol to a coff file which didn't come from a coff file will
8103 lose any debugging information. The `asymbol' structure remembers the
8104 BFD from which the symbol was taken, and on output the back end makes
8105 sure that the same destination target as source target is present.
8107 When the symbols have come from a coff file then all the debugging
8108 information is preserved.
8110 Symbol tables are provided for writing to the back end in a vector
8111 of pointers to pointers. This allows applications like the linker to
8112 accumulate and output large symbol tables without having to do too much
8115 This function runs through the provided symbol table and patches
8116 each symbol marked as a file place holder (`C_FILE') to point to the
8117 next file place holder in the list. It also marks each `offset' field
8118 in the list with the offset from the first symbol of the current symbol.
8120 Another function of this procedure is to turn the canonical value
8121 form of BFD into the form used by coff. Internally, BFD expects symbol
8122 values to be offsets from a section base; so a symbol physically at
8123 0x120, but in a section starting at 0x100, would have the value 0x20.
8124 Coff expects symbols to contain their final value, so symbols have
8125 their values changed at this point to reflect their sum with their
8126 owning section. This transformation uses the `output_section' field of
8127 the `asymbol''s `asection' *Note Sections::.
8129 * `coff_mangle_symbols'
8130 This routine runs though the provided symbol table and uses the
8131 offsets generated by the previous pass and the pointers generated when
8132 the symbol table was read in to create the structured hierarchy
8133 required by coff. It changes each pointer to a symbol into the index
8134 into the symbol table of the asymbol.
8136 * `coff_write_symbols'
8137 This routine runs through the symbol table and patches up the
8138 symbols from their internal form into the coff way, calls the bit
8139 twiddlers, and writes out the table to the file.
8141 3.3.2.5 `coff_symbol_type'
8142 ..........................
8145 The hidden information for an `asymbol' is described in a
8146 `combined_entry_type':

8152 this symbol. Generated by coff_renumber_symbols. */

8192 /* A pointer to the hidden information for this symbol */
8193 combined_entry_type *native;

8489 3.3.2.7 Writing relocations
8490 ...........................
8492 To write relocations, the back end steps though the canonical
8493 relocation table and create an `internal_reloc'. The symbol index to
8494 use is removed from the `offset' field in the symbol table supplied.
8495 The address comes directly from the sum of the section base address and
8496 the relocation offset; the type is dug directly from the howto field.
8497 Then the `internal_reloc' is swapped into the shape of an
8498 `external_reloc' and written out to disk.
8500 3.3.2.8 Reading linenumbers
8501 ...........................
8503 Creating the linenumber table is done by reading in the entire coff
8504 linenumber table, and creating another table for internal use.
8506 A coff linenumber table is structured so that each function is
8507 marked as having a line number of 0. Each line within the function is
8508 an offset from the first line in the function. The base of the line
8509 number information for the table is stored in the symbol associated
8512 Note: The PE format uses line number 0 for a flag indicating a new
8515 The information is copied from the external to the internal table,
8516 and each symbol which marks a function is marked by pointing its...
8518 How does this work ?
8520 3.3.2.9 Reading relocations
8521 ...........................
8523 Coff relocations are easily transformed into the internal BFD form
8526 Reading a coff relocation table is done in the following stages:
8528 * Read the entire coff relocation table into memory.
8530 * Process each relocation in turn; first swap it from the external
8531 to the internal form.
8533 * Turn the symbol referenced in the relocation's symbol index into a
8534 pointer into the canonical symbol table. This table is the same
8535 as the one returned by a call to `bfd_canonicalize_symtab'. The
8536 back end will call that routine and save the result if a
8537 canonicalization hasn't been done.
8539 * The reloc index is turned into a pointer to a howto structure, in
8540 a back end specific way. For instance, the 386 and 960 use the
8541 `r_type' to directly produce an index into a howto table vector;
8542 the 88k subtracts a number from the `r_type' field and creates an
8546 File: bfd.info, Node: elf, Next: mmo, Prev: coff, Up: BFD back ends
8551 BFD support for ELF formats is being worked on. Currently, the best
8552 supported back ends are for sparc and i386 (running svr4 or Solaris 2).
8554 Documentation of the internals of the support code still needs to be
8555 written. The code is changing quickly enough that we haven't bothered
8558 3.4.0.1 `bfd_elf_find_section'
8559 ..............................
8562 struct elf_internal_shdr *bfd_elf_find_section (bfd *abfd, char *name);
8564 Helper functions for GDB to locate the string tables. Since BFD hides
8565 string tables from callers, GDB needs to use an internal hook to find
8566 them. Sun's .stabstr, in particular, isn't even pointed to by the
8567 .stab section, so ordinary mechanisms wouldn't work to find it, even if
8571 File: bfd.info, Node: mmo, Prev: elf, Up: BFD back ends
8576 The mmo object format is used exclusively together with Professor
8577 Donald E. Knuth's educational 64-bit processor MMIX. The simulator
8578 `mmix' which is available at
8579 `http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz'
8580 understands this format. That package also includes a combined
8581 assembler and linker called `mmixal'. The mmo format has no advantages
8582 feature-wise compared to e.g. ELF. It is a simple non-relocatable
8583 object format with no support for archives or debugging information,
8584 except for symbol value information and line numbers (which is not yet
8585 implemented in BFD). See
8586 `http://www-cs-faculty.stanford.edu/~knuth/mmix.html' for more
8587 information about MMIX. The ELF format is used for intermediate object
8588 files in the BFD implementation.
8594 * mmo section mapping::
8597 File: bfd.info, Node: File layout, Next: Symbol-table, Prev: mmo, Up: mmo
8602 The mmo file contents is not partitioned into named sections as with
8603 e.g. ELF. Memory areas is formed by specifying the location of the
8604 data that follows. Only the memory area `0x0000...00' to `0x01ff...ff'
8605 is executable, so it is used for code (and constants) and the area
8606 `0x2000...00' to `0x20ff...ff' is used for writable data. *Note mmo
8609 There is provision for specifying "special data" of 65536 different
8610 types. We use type 80 (decimal), arbitrarily chosen the same as the
8611 ELF `e_machine' number for MMIX, filling it with section information
8612 normally found in ELF objects. *Note mmo section mapping::.
8614 Contents is entered as 32-bit words, xor:ed over previous contents,
8615 always zero-initialized. A word that starts with the byte `0x98' forms
8616 a command called a `lopcode', where the next byte distinguished between
8617 the thirteen lopcodes. The two remaining bytes, called the `Y' and `Z'
8618 fields, or the `YZ' field (a 16-bit big-endian number), are used for
8619 various purposes different for each lopcode. As documented in
8620 `http://www-cs-faculty.stanford.edu/~knuth/mmixal-intro.ps.gz', the
8624 0x98000001. The next word is contents, regardless of whether it
8625 starts with 0x98 or not.
8628 0x9801YYZZ, where `Z' is 1 or 2. This is a location directive,
8629 setting the location for the next data to the next 32-bit word
8630 (for Z = 1) or 64-bit word (for Z = 2), plus Y * 2^56. Normally
8631 `Y' is 0 for the text segment and 2 for the data segment.
8634 0x9802YYZZ. Increase the current location by `YZ' bytes.
8637 0x9803YYZZ, where `Z' is 1 or 2. Store the current location as 64
8638 bits into the location pointed to by the next 32-bit (Z = 1) or
8639 64-bit (Z = 2) word, plus Y * 2^56.
8642 0x9804YYZZ. `YZ' is stored into the current location plus 2 - 4 *
8646 0x980500ZZ. `Z' is 16 or 24. A value `L' derived from the
8647 following 32-bit word are used in a manner similar to `YZ' in
8648 lop_fixr: it is xor:ed into the current location minus 4 * L. The
8649 first byte of the word is 0 or 1. If it is 1, then L = (LOWEST 24
8650 BITS OF WORD) - 2^Z, if 0, then L = (LOWEST 24 BITS OF WORD).
8653 0x9806YYZZ. `Y' is the file number, `Z' is count of 32-bit words.
8654 Set the file number to `Y' and the line counter to 0. The next Z
8655 * 4 bytes contain the file name, padded with zeros if the count is
8656 not a multiple of four. The same `Y' may occur multiple times,
8657 but `Z' must be 0 for all but the first occurrence.
8660 0x9807YYZZ. `YZ' is the line number. Together with lop_file, it
8661 forms the source location for the next 32-bit word. Note that for
8662 each non-lopcode 32-bit word, line numbers are assumed incremented
8666 0x9808YYZZ. `YZ' is the type number. Data until the next lopcode
8667 other than lop_quote forms special data of type `YZ'. *Note mmo
8670 Other types than 80, (or type 80 with a content that does not
8671 parse) is stored in sections named `.MMIX.spec_data.N' where N is
8672 the `YZ'-type. The flags for such a sections say not to allocate
8673 or load the data. The vma is 0. Contents of multiple occurrences
8674 of special data N is concatenated to the data of the previous
8675 lop_spec Ns. The location in data or code at which the lop_spec
8679 0x980901ZZ. The first lopcode in a file. The `Z' field forms the
8680 length of header information in 32-bit words, where the first word
8681 tells the time in seconds since `00:00:00 GMT Jan 1 1970'.
8684 0x980a00ZZ. Z > 32. This lopcode follows after all
8685 content-generating lopcodes in a program. The `Z' field denotes
8686 the value of `rG' at the beginning of the program. The following
8687 256 - Z big-endian 64-bit words are loaded into global registers
8691 0x980b0000. The next-to-last lopcode in a program. Must follow
8692 immediately after the lop_post lopcode and its data. After this
8693 lopcode follows all symbols in a compressed format (*note
8697 0x980cYYZZ. The last lopcode in a program. It must follow the
8698 lop_stab lopcode and its data. The `YZ' field contains the number
8699 of 32-bit words of symbol table information after the preceding
8702 Note that the lopcode "fixups"; `lop_fixr', `lop_fixrx' and
8703 `lop_fixo' are not generated by BFD, but are handled. They are
8704 generated by `mmixal'.
8706 This trivial one-label, one-instruction file:
8710 can be represented this way in mmo:
8712 0x98090101 - lop_pre, one 32-bit word with timestamp.
8714 0x98010002 - lop_loc, text segment, using a 64-bit address.
8715 Note that mmixal does not emit this for the file above.
8716 0x00000000 - Address, high 32 bits.
8717 0x00000000 - Address, low 32 bits.
8718 0x98060002 - lop_file, 2 32-bit words for file-name.
8720 0x2e730000 - ".s\0\0"

8723 0x980a00ff - lop_post, setting $255 to 0.
8726 0x980b0000 - lop_stab for ":Main" = 0, serial 1.
8727 0x203a4040 *Note Symbol-table::.

8737 3.5.2 Symbol table format
8738 -------------------------
8740 From mmixal.w (or really, the generated mmixal.tex) in
8741 `http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz'):
8742 "Symbols are stored and retrieved by means of a `ternary search trie',
8743 following ideas of Bentley and Sedgewick. (See ACM-SIAM Symp. on
8744 Discrete Algorithms `8' (1997), 360-369; R.Sedgewick, `Algorithms in C'
8745 (Reading, Mass. Addison-Wesley, 1998), `15.4'.) Each trie node stores
8746 a character, and there are branches to subtries for the cases where a
8747 given character is less than, equal to, or greater than the character
8748 in the trie. There also is a pointer to a symbol table entry if a
8749 symbol ends at the current node."
8751 So it's a tree encoded as a stream of bytes. The stream of bytes
8752 acts on a single virtual global symbol, adding and removing characters
8753 and signalling complete symbol points. Here, we read the stream and
8754 create symbols at the completion points.
8756 First, there's a control byte `m'. If any of the listed bits in `m'
8757 is nonzero, we execute what stands at the right, in the listed order:
8760 0x40 - Traverse left trie.
8761 (Read a new command byte and recurse.)
8764 0x2f - Read the next byte as a character and store it in the
8765 current character position; increment character position.
8766 Test the bits of `m':
8769 0x80 - The character is 16-bit (so read another byte,
8770 merge into current character.
8773 0xf - We have a complete symbol; parse the type, value
8774 and serial number and do what should be done
8775 with a symbol. The type and length information
8776 is in j = (m & 0xf).
8779 j == 0xf: A register variable. The following
8780 byte tells which register.
8781 j <= 8: An absolute symbol. Read j bytes as the
8782 big-endian number the symbol equals.
8783 A j = 2 with two zero bytes denotes an
8785 j > 8: As with j <= 8, but add (0x20 << 56)
8786 to the value in the following j - 8
8789 Then comes the serial number, as a variant of
8790 uleb128, but better named ubeb128:
8791 Read bytes and shift the previous value left 7
8792 (multiply by 128). Add in the new byte, repeat
8793 until a byte has bit 7 set. The serial number
8794 is the computed value minus 128.
8797 0x20 - Traverse middle trie. (Read a new command byte
8798 and recurse.) Decrement character position.
8801 0x10 - Traverse right trie. (Read a new command byte and
8804 Let's look again at the `lop_stab' for the trivial file (*note File
8807 0x980b0000 - lop_stab for ":Main" = 0, serial 1.
8814 This forms the trivial trie (note that the path between ":" and "M"
8826 016e "n" is the last character in a full symbol, and
8827 with a value represented in one byte.
8829 81 The serial number is 1.

8834 3.5.3 mmo section mapping
8835 -------------------------
8837 The implementation in BFD uses special data type 80 (decimal) to
8838 encapsulate and describe named sections, containing e.g. debug
8839 information. If needed, any datum in the encapsulation will be quoted
8840 using lop_quote. First comes a 32-bit word holding the number of
8841 32-bit words containing the zero-terminated zero-padded segment name.
8842 After the name there's a 32-bit word holding flags describing the
8843 section type. Then comes a 64-bit big-endian word with the section
8844 length (in bytes), then another with the section start address.
8845 Depending on the type of section, the contents might follow,
8846 zero-padded to 32-bit boundary. For a loadable section (such as data
8847 or code), the contents might follow at some later point, not
8848 necessarily immediately, as a lop_loc with the same start address as in
8849 the section description, followed by the contents. This in effect
8850 forms a descriptor that must be emitted before the actual contents.
8851 Sections described this way must not overlap.
8853 For areas that don't have such descriptors, synthetic sections are
8854 formed by BFD. Consecutive contents in the two memory areas
8855 `0x0000...00' to `0x01ff...ff' and `0x2000...00' to `0x20ff...ff' are
8856 entered in sections named `.text' and `.data' respectively. If an area
8857 is not otherwise described, but would together with a neighboring lower
8858 area be less than `0x40000000' bytes long, it is joined with the lower
8859 area and the gap is zero-filled. For other cases, a new section is
8860 formed, named `.MMIX.sec.N'. Here, N is a number, a running count
8861 through the mmo file, starting at 0.
8863 A loadable section specified as:

8922 *****************************************
8924 Version 1.1, March 2000
8926 Copyright (C) 2000, 2003 Free Software Foundation, Inc.
8927 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
8929 Everyone is permitted to copy and distribute verbatim copies
8930 of this license document, but changing it is not allowed.
8935 The purpose of this License is to make a manual, textbook, or other
8936 written document "free" in the sense of freedom: to assure everyone
8937 the effective freedom to copy and redistribute it, with or without
8938 modifying it, either commercially or noncommercially. Secondarily,
8939 this License preserves for the author and publisher a way to get
8940 credit for their work, while not being considered responsible for
8941 modifications made by others.
8943 This License is a kind of "copyleft", which means that derivative
8944 works of the document must themselves be free in the same sense.
8945 It complements the GNU General Public License, which is a copyleft
8946 license designed for free software.
8948 We have designed this License in order to use it for manuals for
8949 free software, because free software needs free documentation: a
8950 free program should come with manuals providing the same freedoms
8951 that the software does. But this License is not limited to
8952 software manuals; it can be used for any textual work, regardless
8953 of subject matter or whether it is published as a printed book.
8954 We recommend this License principally for works whose purpose is
8955 instruction or reference.
8958 1. APPLICABILITY AND DEFINITIONS
8960 This License applies to any manual or other work that contains a
8961 notice placed by the copyright holder saying it can be distributed
8962 under the terms of this License. The "Document", below, refers to
8963 any such manual or work. Any member of the public is a licensee,
8964 and is addressed as "you."
8966 A "Modified Version" of the Document means any work containing the
8967 Document or a portion of it, either copied verbatim, or with
8968 modifications and/or translated into another language.
8970 A "Secondary Section" is a named appendix or a front-matter
8971 section of the Document that deals exclusively with the
8972 relationship of the publishers or authors of the Document to the
8973 Document's overall subject (or to related matters) and contains
8974 nothing that could fall directly within that overall subject.
8975 (For example, if the Document is in part a textbook of
8976 mathematics, a Secondary Section may not explain any mathematics.)
8977 The relationship could be a matter of historical connection with
8978 the subject or with related matters, or of legal, commercial,
8979 philosophical, ethical or political position regarding them.
8981 The "Invariant Sections" are certain Secondary Sections whose
8982 titles are designated, as being those of Invariant Sections, in
8983 the notice that says that the Document is released under this
8986 The "Cover Texts" are certain short passages of text that are
8987 listed, as Front-Cover Texts or Back-Cover Texts, in the notice
8988 that says that the Document is released under this License.
8990 A "Transparent" copy of the Document means a machine-readable copy,
8991 represented in a format whose specification is available to the
8992 general public, whose contents can be viewed and edited directly
8993 and straightforwardly with generic text editors or (for images
8994 composed of pixels) generic paint programs or (for drawings) some
8995 widely available drawing editor, and that is suitable for input to
8996 text formatters or for automatic translation to a variety of
8997 formats suitable for input to text formatters. A copy made in an
8998 otherwise Transparent file format whose markup has been designed
8999 to thwart or discourage subsequent modification by readers is not
9000 Transparent. A copy that is not "Transparent" is called "Opaque."
9002 Examples of suitable formats for Transparent copies include plain
9003 ASCII without markup, Texinfo input format, LaTeX input format,
9004 SGML or XML using a publicly available DTD, and
9005 standard-conforming simple HTML designed for human modification.
9006 Opaque formats include PostScript, PDF, proprietary formats that
9007 can be read and edited only by proprietary word processors, SGML
9008 or XML for which the DTD and/or processing tools are not generally
9009 available, and the machine-generated HTML produced by some word
9010 processors for output purposes only.
9012 The "Title Page" means, for a printed book, the title page itself,
9013 plus such following pages as are needed to hold, legibly, the
9014 material this License requires to appear in the title page. For
9015 works in formats which do not have any title page as such, "Title
9016 Page" means the text near the most prominent appearance of the
9017 work's title, preceding the beginning of the body of the text.
9021 You may copy and distribute the Document in any medium, either
9022 commercially or noncommercially, provided that this License, the
9023 copyright notices, and the license notice saying this License
9024 applies to the Document are reproduced in all copies, and that you
9025 add no other conditions whatsoever to those of this License. You
9026 may not use technical measures to obstruct or control the reading
9027 or further copying of the copies you make or distribute. However,
9028 you may accept compensation in exchange for copies. If you
9029 distribute a large enough number of copies you must also follow
9030 the conditions in section 3.
9032 You may also lend copies, under the same conditions stated above,
9033 and you may publicly display copies.
9035 3. COPYING IN QUANTITY
9037 If you publish printed copies of the Document numbering more than
9038 100, and the Document's license notice requires Cover Texts, you
9039 must enclose the copies in covers that carry, clearly and legibly,
9040 all these Cover Texts: Front-Cover Texts on the front cover, and
9041 Back-Cover Texts on the back cover. Both covers must also clearly
9042 and legibly identify you as the publisher of these copies. The
9043 front cover must present the full title with all words of the
9044 title equally prominent and visible. You may add other material
9045 on the covers in addition. Copying with changes limited to the
9046 covers, as long as they preserve the title of the Document and
9047 satisfy these conditions, can be treated as verbatim copying in
9050 If the required texts for either cover are too voluminous to fit
9051 legibly, you should put the first ones listed (as many as fit
9052 reasonably) on the actual cover, and continue the rest onto
9055 If you publish or distribute Opaque copies of the Document
9056 numbering more than 100, you must either include a
9057 machine-readable Transparent copy along with each Opaque copy, or
9058 state in or with each Opaque copy a publicly-accessible
9059 computer-network location containing a complete Transparent copy
9060 of the Document, free of added material, which the general
9061 network-using public has access to download anonymously at no
9062 charge using public-standard network protocols. If you use the
9063 latter option, you must take reasonably prudent steps, when you
9064 begin distribution of Opaque copies in quantity, to ensure that
9065 this Transparent copy will remain thus accessible at the stated
9066 location until at least one year after the last time you
9067 distribute an Opaque copy (directly or through your agents or
9068 retailers) of that edition to the public.
9070 It is requested, but not required, that you contact the authors of
9071 the Document well before redistributing any large number of
9072 copies, to give them a chance to provide you with an updated
9073 version of the Document.
9077 You may copy and distribute a Modified Version of the Document
9078 under the conditions of sections 2 and 3 above, provided that you
9079 release the Modified Version under precisely this License, with
9080 the Modified Version filling the role of the Document, thus
9081 licensing distribution and modification of the Modified Version to
9082 whoever possesses a copy of it. In addition, you must do these
9083 things in the Modified Version:
9085 A. Use in the Title Page (and on the covers, if any) a title
9086 distinct from that of the Document, and from those of previous
9087 versions (which should, if there were any, be listed in the
9088 History section of the Document). You may use the same title
9089 as a previous version if the original publisher of that version
9091 B. List on the Title Page, as authors, one or more persons or
9092 entities responsible for authorship of the modifications in the
9093 Modified Version, together with at least five of the principal
9094 authors of the Document (all of its principal authors, if it
9095 has less than five).
9096 C. State on the Title page the name of the publisher of the
9097 Modified Version, as the publisher.
9098 D. Preserve all the copyright notices of the Document.
9099 E. Add an appropriate copyright notice for your modifications
9100 adjacent to the other copyright notices.
9101 F. Include, immediately after the copyright notices, a license
9102 notice giving the public permission to use the Modified Version
9103 under the terms of this License, in the form shown in the
9105 G. Preserve in that license notice the full lists of Invariant
9106 Sections and required Cover Texts given in the Document's
9108 H. Include an unaltered copy of this License.
9109 I. Preserve the section entitled "History", and its title, and add
9110 to it an item stating at least the title, year, new authors, and
9111 publisher of the Modified Version as given on the Title Page.
9112 If there is no section entitled "History" in the Document,
9113 create one stating the title, year, authors, and publisher of
9114 the Document as given on its Title Page, then add an item
9115 describing the Modified Version as stated in the previous
9117 J. Preserve the network location, if any, given in the Document for
9118 public access to a Transparent copy of the Document, and
9119 likewise the network locations given in the Document for
9120 previous versions it was based on. These may be placed in the
9121 "History" section. You may omit a network location for a work
9122 that was published at least four years before the Document
9123 itself, or if the original publisher of the version it refers
9124 to gives permission.
9125 K. In any section entitled "Acknowledgements" or "Dedications",
9126 preserve the section's title, and preserve in the section all the
9127 substance and tone of each of the contributor acknowledgements
9128 and/or dedications given therein.
9129 L. Preserve all the Invariant Sections of the Document,
9130 unaltered in their text and in their titles. Section numbers
9131 or the equivalent are not considered part of the section titles.
9132 M. Delete any section entitled "Endorsements." Such a section
9133 may not be included in the Modified Version.
9134 N. Do not retitle any existing section as "Endorsements" or to
9135 conflict in title with any Invariant Section.
9137 If the Modified Version includes new front-matter sections or
9138 appendices that qualify as Secondary Sections and contain no
9139 material copied from the Document, you may at your option
9140 designate some or all of these sections as invariant. To do this,
9141 add their titles to the list of Invariant Sections in the Modified
9142 Version's license notice. These titles must be distinct from any
9143 other section titles.
9145 You may add a section entitled "Endorsements", provided it contains
9146 nothing but endorsements of your Modified Version by various
9147 parties-for example, statements of peer review or that the text has
9148 been approved by an organization as the authoritative definition
9151 You may add a passage of up to five words as a Front-Cover Text,
9152 and a passage of up to 25 words as a Back-Cover Text, to the end
9153 of the list of Cover Texts in the Modified Version. Only one
9154 passage of Front-Cover Text and one of Back-Cover Text may be
9155 added by (or through arrangements made by) any one entity. If the
9156 Document already includes a cover text for the same cover,
9157 previously added by you or by arrangement made by the same entity
9158 you are acting on behalf of, you may not add another; but you may
9159 replace the old one, on explicit permission from the previous
9160 publisher that added the old one.
9162 The author(s) and publisher(s) of the Document do not by this
9163 License give permission to use their names for publicity for or to
9164 assert or imply endorsement of any Modified Version.
9166 5. COMBINING DOCUMENTS
9168 You may combine the Document with other documents released under
9169 this License, under the terms defined in section 4 above for
9170 modified versions, provided that you include in the combination
9171 all of the Invariant Sections of all of the original documents,
9172 unmodified, and list them all as Invariant Sections of your
9173 combined work in its license notice.
9175 The combined work need only contain one copy of this License, and
9176 multiple identical Invariant Sections may be replaced with a single
9177 copy. If there are multiple Invariant Sections with the same name
9178 but different contents, make the title of each such section unique
9179 by adding at the end of it, in parentheses, the name of the
9180 original author or publisher of that section if known, or else a
9181 unique number. Make the same adjustment to the section titles in
9182 the list of Invariant Sections in the license notice of the
9185 In the combination, you must combine any sections entitled
9186 "History" in the various original documents, forming one section
9187 entitled "History"; likewise combine any sections entitled
9188 "Acknowledgements", and any sections entitled "Dedications." You
9189 must delete all sections entitled "Endorsements."
9191 6. COLLECTIONS OF DOCUMENTS
9193 You may make a collection consisting of the Document and other
9194 documents released under this License, and replace the individual
9195 copies of this License in the various documents with a single copy
9196 that is included in the collection, provided that you follow the
9197 rules of this License for verbatim copying of each of the
9198 documents in all other respects.
9200 You may extract a single document from such a collection, and
9201 distribute it individually under this License, provided you insert
9202 a copy of this License into the extracted document, and follow
9203 this License in all other respects regarding verbatim copying of
9206 7. AGGREGATION WITH INDEPENDENT WORKS
9208 A compilation of the Document or its derivatives with other
9209 separate and independent documents or works, in or on a volume of
9210 a storage or distribution medium, does not as a whole count as a
9211 Modified Version of the Document, provided no compilation
9212 copyright is claimed for the compilation. Such a compilation is
9213 called an "aggregate", and this License does not apply to the
9214 other self-contained works thus compiled with the Document, on
9215 account of their being thus compiled, if they are not themselves
9216 derivative works of the Document.
9218 If the Cover Text requirement of section 3 is applicable to these
9219 copies of the Document, then if the Document is less than one
9220 quarter of the entire aggregate, the Document's Cover Texts may be
9221 placed on covers that surround only the Document within the
9222 aggregate. Otherwise they must appear on covers around the whole
9227 Translation is considered a kind of modification, so you may
9228 distribute translations of the Document under the terms of section
9229 4. Replacing Invariant Sections with translations requires special
9230 permission from their copyright holders, but you may include
9231 translations of some or all Invariant Sections in addition to the
9232 original versions of these Invariant Sections. You may include a
9233 translation of this License provided that you also include the
9234 original English version of this License. In case of a
9235 disagreement between the translation and the original English
9236 version of this License, the original English version will prevail.
9240 You may not copy, modify, sublicense, or distribute the Document
9241 except as expressly provided for under this License. Any other
9242 attempt to copy, modify, sublicense or distribute the Document is
9243 void, and will automatically terminate your rights under this
9244 License. However, parties who have received copies, or rights,
9245 from you under this License will not have their licenses
9246 terminated so long as such parties remain in full compliance.
9248 10. FUTURE REVISIONS OF THIS LICENSE
9250 The Free Software Foundation may publish new, revised versions of
9251 the GNU Free Documentation License from time to time. Such new
9252 versions will be similar in spirit to the present version, but may
9253 differ in detail to address new problems or concerns. See
9254 http://www.gnu.org/copyleft/.
9256 Each version of the License is given a distinguishing version
9257 number. If the Document specifies that a particular numbered
9258 version of this License "or any later version" applies to it, you
9259 have the option of following the terms and conditions either of
9260 that specified version or of any later version that has been
9261 published (not as a draft) by the Free Software Foundation. If
9262 the Document does not specify a version number of this License,
9263 you may choose any version ever published (not as a draft) by the
9264 Free Software Foundation.
9267 ADDENDUM: How to use this License for your documents
9268 ====================================================
9270 To use this License in a document you have written, include a copy of
9271 the License in the document and put the following copyright and license
9272 notices just after the title page:
9274 Copyright (C) YEAR YOUR NAME.
9275 Permission is granted to copy, distribute and/or modify this document
9276 under the terms of the GNU Free Documentation License, Version 1.1
9277 or any later version published by the Free Software Foundation;
9278 with the Invariant Sections being LIST THEIR TITLES, with the
9279 Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
9280 A copy of the license is included in the section entitled "GNU
9281 Free Documentation License."
9283 If you have no Invariant Sections, write "with no Invariant Sections"
9284 instead of saying which ones are invariant. If you have no Front-Cover
9285 Texts, write "no Front-Cover Texts" instead of "Front-Cover Texts being
9286 LIST"; likewise for Back-Cover Texts.
9288 If your document contains nontrivial examples of program code, we
9289 recommend releasing these examples in parallel under your choice of
9290 free software license, such as the GNU General Public License, to
9291 permit their use in free software.
