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

62 File: bfd.info, Node: History, Next: How It Works, Prev: Overview, Up: Overview
67 One spur behind BFD was the desire, on the part of the GNU 960 team at
68 Intel Oregon, for interoperability of applications on their COFF and
69 b.out file formats. Cygnus was providing GNU support for the team, and
70 was contracted to provide the required functionality.
72 The name came from a conversation David Wallace was having with
73 Richard Stallman about the library: RMS said that it would be quite
74 hard--David said "BFD". Stallman was right, but the name stuck.
76 At the same time, Ready Systems wanted much the same thing, but for
77 different object file formats: IEEE-695, Oasys, Srecords, a.out and 68k
80 BFD was first implemented by members of Cygnus Support; Steve
81 Chamberlain (`sac@cygnus.com'), John Gilmore (`gnu@cygnus.com'), K.
82 Richard Pixley (`rich@cygnus.com') and David Henkel-Wallace
86 File: bfd.info, Node: How It Works, Next: What BFD Version 2 Can Do, Prev: History, Up: Overview
91 To use the library, include `bfd.h' and link with `libbfd.a'.
93 BFD provides a common interface to the parts of an object file for a
96 When an application successfully opens a target file (object,
97 archive, or whatever), a pointer to an internal structure is returned.
98 This pointer points to a structure called `bfd', described in `bfd.h'.
99 Our convention is to call this pointer a BFD, and instances of it
100 within code `abfd'. All operations on the target object file are
101 applied as methods to the BFD. The mapping is defined within `bfd.h'
102 in a set of macros, all beginning with `bfd_' to reduce namespace
105 For example, this sequence does what you would probably expect:
106 return the number of sections in an object file attached to a BFD
111 unsigned int number_of_sections (abfd)
114 return bfd_count_sections (abfd);
117 The abstraction used within BFD is that an object file has:
121 * a number of sections containing raw data (*note Sections::),
123 * a set of relocations (*note Relocations::), and
125 * some symbol information (*note Symbols::).
126 Also, BFDs opened for archives have the additional attribute of an
127 index and contain subordinate BFDs. This approach is fine for a.out and
128 coff, but loses efficiency when applied to formats such as S-records and
132 File: bfd.info, Node: What BFD Version 2 Can Do, Prev: How It Works, Up: Overview
134 1.3 What BFD Version 2 Can Do
135 =============================
137 When an object file is opened, BFD subroutines automatically determine
138 the format of the input object file. They then build a descriptor in
139 memory with pointers to routines that will be used to access elements of
140 the object file's data structures.
142 As different information from the object files is required, BFD
143 reads from different sections of the file and processes them. For
144 example, a very common operation for the linker is processing symbol
145 tables. Each BFD back end provides a routine for converting between
146 the object file's representation of symbols and an internal canonical
147 format. When the linker asks for the symbol table of an object file, it
148 calls through a memory pointer to the routine from the relevant BFD
149 back end which reads and converts the table into a canonical form. The
150 linker then operates upon the canonical form. When the link is finished
151 and the linker writes the output file's symbol table, another BFD back
152 end routine is called to take the newly created symbol table and
153 convert it into the chosen output format.
157 * BFD information loss:: Information Loss
158 * Canonical format:: The BFD canonical object-file format
161 File: bfd.info, Node: BFD information loss, Next: Canonical format, Up: What BFD Version 2 Can Do
163 1.3.1 Information Loss
164 ----------------------
166 _Information can be lost during output._ The output formats supported
167 by BFD do not provide identical facilities, and information which can
168 be described in one form has nowhere to go in another format. One
169 example of this is alignment information in `b.out'. There is nowhere
170 in an `a.out' format file to store alignment information on the
171 contained data, so when a file is linked from `b.out' and an `a.out'
172 image is produced, alignment information will not propagate to the
173 output file. (The linker will still use the alignment information
174 internally, so the link is performed correctly).
176 Another example is COFF section names. COFF files may contain an
177 unlimited number of sections, each one with a textual section name. If
178 the target of the link is a format which does not have many sections
179 (e.g., `a.out') or has sections without names (e.g., the Oasys format),
180 the link cannot be done simply. You can circumvent this problem by
181 describing the desired input-to-output section mapping with the linker
184 _Information can be lost during canonicalization._ The BFD internal
185 canonical form of the external formats is not exhaustive; there are
186 structures in input formats for which there is no direct representation
187 internally. This means that the BFD back ends cannot maintain all
188 possible data richness through the transformation between external to
189 internal and back to external formats.
191 This limitation is only a problem when an application reads one
192 format and writes another. Each BFD back end is responsible for
193 maintaining as much data as possible, and the internal BFD canonical
194 form has structures which are opaque to the BFD core, and exported only
195 to the back ends. When a file is read in one format, the canonical form
196 is generated for BFD and the application. At the same time, the back
197 end saves away any information which may otherwise be lost. If the data
198 is then written back in the same format, the back end routine will be
199 able to use the canonical form provided by the BFD core as well as the
200 information it prepared earlier. Since there is a great deal of
201 commonality between back ends, there is no information lost when
202 linking or copying big endian COFF to little endian COFF, or `a.out' to
203 `b.out'. When a mixture of formats is linked, the information is only
204 lost from the files whose format differs from the destination.
207 File: bfd.info, Node: Canonical format, Prev: BFD information loss, Up: What BFD Version 2 Can Do
209 1.3.2 The BFD canonical object-file format
210 ------------------------------------------
212 The greatest potential for loss of information occurs when there is the
213 least overlap between the information provided by the source format,
214 that stored by the canonical format, and that needed by the destination
215 format. A brief description of the canonical form may help you
216 understand which kinds of data you can count on preserving across
220 Information stored on a per-file basis includes target machine
221 architecture, particular implementation format type, a demand
222 pageable bit, and a write protected bit. Information like Unix
223 magic numbers is not stored here--only the magic numbers' meaning,
224 so a `ZMAGIC' file would have both the demand pageable bit and the
225 write protected text bit set. The byte order of the target is
226 stored on a per-file basis, so that big- and little-endian object
227 files may be used with one another.
230 Each section in the input file contains the name of the section,
231 the section's original address in the object file, size and
232 alignment information, various flags, and pointers into other BFD
236 Each symbol contains a pointer to the information for the object
237 file which originally defined it, its name, its value, and various
238 flag bits. When a BFD back end reads in a symbol table, it
239 relocates all symbols to make them relative to the base of the
240 section where they were defined. Doing this ensures that each
241 symbol points to its containing section. Each symbol also has a
242 varying amount of hidden private data for the BFD back end. Since
243 the symbol points to the original file, the private data format
244 for that symbol is accessible. `ld' can operate on a collection
245 of symbols of wildly different formats without problems.
247 Normal global and simple local symbols are maintained on output,
248 so an output file (no matter its format) will retain symbols
249 pointing to functions and to global, static, and common variables.
250 Some symbol information is not worth retaining; in `a.out', type
251 information is stored in the symbol table as long symbol names.
252 This information would be useless to most COFF debuggers; the
253 linker has command line switches to allow users to throw it away.
255 There is one word of type information within the symbol, so if the
256 format supports symbol type information within symbols (for
257 example, COFF, IEEE, Oasys) and the type is simple enough to fit
258 within one word (nearly everything but aggregates), the
259 information will be preserved.
262 Each canonical BFD relocation record contains a pointer to the
263 symbol to relocate to, the offset of the data to relocate, the
264 section the data is in, and a pointer to a relocation type
265 descriptor. Relocation is performed by passing messages through
266 the relocation type descriptor and the symbol pointer. Therefore,
267 relocations can be performed on output data using a relocation
268 method that is only available in one of the input formats. For
269 instance, Oasys provides a byte relocation format. A relocation
270 record requesting this relocation type would point indirectly to a
271 routine to perform this, so the relocation may be performed on a
272 byte being written to a 68k COFF file, even though 68k COFF has no
273 such relocation type.
276 Object formats can contain, for debugging purposes, some form of
277 mapping between symbols, source line numbers, and addresses in the
278 output file. These addresses have to be relocated along with the
279 symbol information. Each symbol with an associated list of line
280 number records points to the first record of the list. The head
281 of a line number list consists of a pointer to the symbol, which
282 allows finding out the address of the function whose line number
283 is being described. The rest of the list is made up of pairs:
284 offsets into the section and line numbers. Any format which can
285 simply derive this information can pass it successfully between
286 formats (COFF, IEEE and Oasys).

297 A BFD has type `bfd'; objects of this type are the cornerstone of any

524 2.2.1.2 `bfd_set_error'
525 .......................
528 void bfd_set_error (bfd_error_type error_tag, ...);
530 Set the BFD error condition to be ERROR_TAG. If ERROR_TAG is
531 bfd_error_on_input, then this function takes two more parameters, the
532 input bfd where the error occurred, and the bfd_error_type error.
538 const char *bfd_errmsg (bfd_error_type error_tag);
540 Return a string describing the error ERROR_TAG, or the system error if
541 ERROR_TAG is `bfd_error_system_call'.
547 void bfd_perror (const char *message);
549 Print to the standard error stream a string describing the last BFD
550 error that occurred, or the last system error if the last BFD error was
551 a system call failure. If MESSAGE is non-NULL and non-empty, the error
552 string printed is preceded by MESSAGE, a colon, and a space. It is

575 2.2.2.2 `bfd_set_error_program_name'
576 ....................................
579 void bfd_set_error_program_name (const char *);
581 Set the program name to use when printing a BFD error. This is printed
582 before the error message followed by a colon and space. The string
583 must not be changed after it is passed to this function.
585 2.2.2.3 `bfd_get_error_handler'
586 ...............................
589 bfd_error_handler_type bfd_get_error_handler (void);
591 Return the BFD error handler function.
596 2.3.1 Miscellaneous functions
597 -----------------------------
599 2.3.1.1 `bfd_get_reloc_upper_bound'
600 ...................................
603 long bfd_get_reloc_upper_bound (bfd *abfd, asection *sect);
605 Return the number of bytes required to store the relocation information
606 associated with section SECT attached to bfd ABFD. If an error occurs,
609 2.3.1.2 `bfd_canonicalize_reloc'
610 ................................
613 long bfd_canonicalize_reloc
614 (bfd *abfd, asection *sec, arelent **loc, asymbol **syms);
616 Call the back end associated with the open BFD ABFD and translate the
617 external form of the relocation information attached to SEC into the
618 internal canonical form. Place the table into memory at LOC, which has
619 been preallocated, usually by a call to `bfd_get_reloc_upper_bound'.
620 Returns the number of relocs, or -1 on error.
622 The SYMS table is also needed for horrible internal magic reasons.
624 2.3.1.3 `bfd_set_reloc'
625 .......................
629 (bfd *abfd, asection *sec, arelent **rel, unsigned int count);
631 Set the relocation pointer and count within section SEC to the values
632 REL and COUNT. The argument ABFD is ignored.
634 2.3.1.4 `bfd_set_file_flags'
635 ............................
638 bfd_boolean bfd_set_file_flags (bfd *abfd, flagword flags);
640 Set the flag word in the BFD ABFD to the value FLAGS.
643 * `bfd_error_wrong_format' - The target bfd was not of object format.
645 * `bfd_error_invalid_operation' - The target bfd was open for
648 * `bfd_error_invalid_operation' - The flag word contained a bit
649 which was not applicable to the type of file. E.g., an attempt
650 was made to set the `D_PAGED' bit on a BFD format which does not
651 support demand paging.
653 2.3.1.5 `bfd_get_arch_size'
654 ...........................
657 int bfd_get_arch_size (bfd *abfd);
659 Returns the architecture address size, in bits, as determined by the
660 object file's format. For ELF, this information is included in the
664 Returns the arch size in bits if known, `-1' otherwise.
666 2.3.1.6 `bfd_get_sign_extend_vma'
667 .................................
670 int bfd_get_sign_extend_vma (bfd *abfd);
672 Indicates if the target architecture "naturally" sign extends an
673 address. Some architectures implicitly sign extend address values when
674 they are converted to types larger than the size of an address. For
675 instance, bfd_get_start_address() will return an address sign extended
676 to fill a bfd_vma when this is the case.
679 Returns `1' if the target architecture is known to sign extend
680 addresses, `0' if the target architecture is known to not sign extend
681 addresses, and `-1' otherwise.
683 2.3.1.7 `bfd_set_start_address'
684 ...............................
687 bfd_boolean bfd_set_start_address (bfd *abfd, bfd_vma vma);
689 Make VMA the entry point of output BFD ABFD.
692 Returns `TRUE' on success, `FALSE' otherwise.
694 2.3.1.8 `bfd_get_gp_size'
695 .........................
698 unsigned int bfd_get_gp_size (bfd *abfd);
700 Return the maximum size of objects to be optimized using the GP
701 register under MIPS ECOFF. This is typically set by the `-G' argument
702 to the compiler, assembler or linker.
704 2.3.1.9 `bfd_set_gp_size'
705 .........................
708 void bfd_set_gp_size (bfd *abfd, unsigned int i);
710 Set the maximum size of objects to be optimized using the GP register
711 under ECOFF or MIPS ELF. This is typically set by the `-G' argument to
712 the compiler, assembler or linker.
714 2.3.1.10 `bfd_scan_vma'
715 .......................
718 bfd_vma bfd_scan_vma (const char *string, const char **end, int base);
720 Convert, like `strtoul', a numerical expression STRING into a `bfd_vma'
721 integer, and return that integer. (Though without as many bells and
722 whistles as `strtoul'.) The expression is assumed to be unsigned
723 (i.e., positive). If given a BASE, it is used as the base for
724 conversion. A base of 0 causes the function to interpret the string in
725 hex if a leading "0x" or "0X" is found, otherwise in octal if a leading
726 zero is found, otherwise in decimal.
728 If the value would overflow, the maximum `bfd_vma' value is returned.

736 Copy private BFD header information from the BFD IBFD to the the BFD
737 OBFD. This copies information that may require sections to exist, but
738 does not require symbol tables. Return `true' on success, `false' on

890 2.3.1.16 `bfd_alt_mach_code'
891 ............................
894 bfd_boolean bfd_alt_mach_code (bfd *abfd, int alternative);
896 When more than one machine code number is available for the same
897 machine type, this function can be used to switch between the preferred
898 one (alternative == 0) and any others. Currently, only ELF supports
899 this feature, with up to two alternate machine codes.

913 2.3.1.17 `bfd_preserve_save'
914 ............................
917 bfd_boolean bfd_preserve_save (bfd *, struct bfd_preserve *);
919 When testing an object for compatibility with a particular target
920 back-end, the back-end object_p function needs to set up certain fields
921 in the bfd on successfully recognizing the object. This typically
922 happens in a piecemeal fashion, with failures possible at many points.
923 On failure, the bfd is supposed to be restored to its initial state,
924 which is virtually impossible. However, restoring a subset of the bfd
925 state works in practice. This function stores the subset and
926 reinitializes the bfd.
928 2.3.1.18 `bfd_preserve_restore'
929 ...............................
932 void bfd_preserve_restore (bfd *, struct bfd_preserve *);
934 This function restores bfd state saved by bfd_preserve_save. If MARKER
935 is non-NULL in struct bfd_preserve then that block and all subsequently
936 bfd_alloc'd memory is freed.
938 2.3.1.19 `bfd_preserve_finish'
939 ..............................
942 void bfd_preserve_finish (bfd *, struct bfd_preserve *);
944 This function should be called when the bfd state saved by
945 bfd_preserve_save is no longer needed. ie. when the back-end object_p
946 function returns with success.

1019 ........................
1022 long bfd_get_mtime (bfd *abfd);
1024 Return the file modification time (as read from the file system, or
1025 from the archive header for archive members).
1027 2.3.1.26 `bfd_get_size'
1028 .......................
1031 long bfd_get_size (bfd *abfd);
1033 Return the file size (as read from file system) for the file associated
1036 The initial motivation for, and use of, this routine is not so we
1037 can get the exact size of the object the BFD applies to, since that
1038 might not be generally possible (archive members for example). It
1039 would be ideal if someone could eventually modify it so that such
1040 results were guaranteed.
1042 Instead, we want to ask questions like "is this NNN byte sized
1043 object I'm about to try read from file offset YYY reasonable?" As as
1044 example of where we might do this, some object formats use string
1045 tables for which the first `sizeof (long)' bytes of the table contain
1046 the size of the table itself, including the size bytes. If an
1047 application tries to read what it thinks is one of these string tables,
1048 without some way to validate the size, and for some reason the size is
1049 wrong (byte swapping error, wrong location for the string table, etc.),
1050 the only clue is likely to be a read error when it tries to read the
1051 table, or a "virtual memory exhausted" error when it tries to allocate
1052 15 bazillon bytes of space for the 15 bazillon byte table it is about
1053 to read. This function at least allows us to answer the question, "is
1054 the size reasonable?".

1071 * Linker Functions::
1075 File: bfd.info, Node: Memory Usage, Next: Initialization, Prev: BFD front end, Up: BFD front end
1080 BFD keeps all of its internal structures in obstacks. There is one
1081 obstack per open BFD file, into which the current state is stored. When
1082 a BFD is closed, the obstack is deleted, and so everything which has
1083 been allocated by BFD for the closing file is thrown away.
1085 BFD does not free anything created by an application, but pointers
1086 into `bfd' structures become invalid on a `bfd_close'; for example,
1087 after a `bfd_close' the vector passed to `bfd_canonicalize_symtab' is
1088 still around, since it has been allocated by the application, but the
1089 data that it pointed to are lost.
1091 The general rule is to not close a BFD until all operations dependent
1092 upon data from the BFD have been completed, or all the data from within
1093 the file has been copied. To help with the management of memory, there
1094 is a function (`bfd_alloc_size') which returns the number of bytes in
1095 obstacks associated with the supplied BFD. This could be used to select
1096 the greediest open BFD, close it to reclaim the memory, perform some
1097 operation and reopen the BFD again, to get a fresh copy of the data

1106 2.5.1 Initialization functions
1107 ------------------------------
1109 These are the functions that handle initializing a BFD.
1115 void bfd_init (void);
1117 This routine must be called before any other BFD function to initialize
1118 magical internal data structures.

1126 The raw data contained within a BFD is maintained through the section
1127 abstraction. A single BFD may have any number of sections. It keeps
1128 hold of them by pointing to the first; each one points to the next in
1131 Sections are supported in BFD in `section.c'.
1137 * typedef asection::
1138 * section prototypes::
1141 File: bfd.info, Node: Section Input, Next: Section Output, Prev: Sections, Up: Sections
1146 When a BFD is opened for reading, the section structures are created
1147 and attached to the BFD.
1149 Each section has a name which describes the section in the outside
1150 world--for example, `a.out' would contain at least three sections,
1151 called `.text', `.data' and `.bss'.
1153 Names need not be unique; for example a COFF file may have several
1154 sections named `.data'.
1156 Sometimes a BFD will contain more than the "natural" number of
1157 sections. A back end may attach other sections containing constructor
1158 data, or an application may add a section (using `bfd_make_section') to
1159 the sections attached to an already open BFD. For example, the linker
1160 creates an extra section `COMMON' for each input file's BFD to hold
1161 information about common storage.
1163 The raw data is not necessarily read in when the section descriptor
1164 is created. Some targets may leave the data in place until a
1165 `bfd_get_section_contents' call is made. Other back ends may read in
1166 all the data at once. For example, an S-record file has to be read
1167 once to determine the size of the data. An IEEE-695 file doesn't
1168 contain raw data in sections, but data and relocation expressions
1169 intermixed, so the data area has to be parsed to get out the data and
1173 File: bfd.info, Node: Section Output, Next: typedef asection, Prev: Section Input, Up: Sections
1175 2.6.2 Section output
1176 --------------------
1178 To write a new object style BFD, the various sections to be written
1179 have to be created. They are attached to the BFD in the same way as
1180 input sections; data is written to the sections using
1181 `bfd_set_section_contents'.
1183 Any program that creates or combines sections (e.g., the assembler
1184 and linker) must use the `asection' fields `output_section' and
1185 `output_offset' to indicate the file sections to which each section
1186 must be written. (If the section is being created from scratch,
1187 `output_section' should probably point to the section itself and
1188 `output_offset' should probably be zero.)
1190 The data to be written comes from input sections attached (via
1191 `output_section' pointers) to the output sections. The output section
1192 structure can be considered a filter for the input section: the output
1193 section determines the vma of the output data and the name, but the
1194 input section determines the offset into the output section of the data
1197 E.g., to create a section "O", starting at 0x100, 0x123 long,
1198 containing two subsections, "A" at offset 0x0 (i.e., at vma 0x100) and
1199 "B" at offset 0x20 (i.e., at vma 0x120) the `asection' structures would
1205 output_section -----------> section name "O"
1207 section name "B" | size 0x123
1208 output_offset 0x20 |
1210 output_section --------|
1215 The data within a section is stored in a "link_order". These are much
1216 like the fixups in `gas'. The link_order abstraction allows a section
1217 to grow and shrink within itself.
1219 A link_order knows how big it is, and which is the next link_order
1220 and where the raw data for it is; it also points to a list of
1221 relocations which apply to it.
1223 The link_order is used by the linker to perform relaxing on final
1224 code. The compiler creates code which is as big as necessary to make
1225 it work without relaxing, and the user can select whether to relax.
1226 Sometimes relaxing takes a lot of time. The linker runs around the
1227 relocations to see if any are attached to data which can be shrunk, if
1228 so it does it on a link_order by link_order basis.

1764 ------------------------
1766 These are the functions exported by the section handling part of BFD.
1768 2.6.5.1 `bfd_section_list_clear'
1769 ................................
1772 void bfd_section_list_clear (bfd *);
1774 Clears the section list, and also resets the section count and hash
1777 2.6.5.2 `bfd_get_section_by_name'
1778 .................................
1781 asection *bfd_get_section_by_name (bfd *abfd, const char *name);
1783 Run through ABFD and return the one of the `asection's whose name
1784 matches NAME, otherwise `NULL'. *Note Sections::, for more information.
1786 This should only be used in special cases; the normal way to process
1787 all sections of a given name is to use `bfd_map_over_sections' and
1788 `strcmp' on the name (or better yet, base it on the section flags or
1789 something else) for each section.
1791 2.6.5.3 `bfd_get_section_by_name_if'
1792 ....................................
1795 asection *bfd_get_section_by_name_if
1798 bfd_boolean (*func) (bfd *abfd, asection *sect, void *obj),
1801 Call the provided function FUNC for each section attached to the BFD
1802 ABFD whose name matches NAME, passing OBJ as an argument. The function
1803 will be called as if by
1805 func (abfd, the_section, obj);
1807 It returns the first section for which FUNC returns true, otherwise
1810 2.6.5.4 `bfd_get_unique_section_name'
1811 .....................................
1814 char *bfd_get_unique_section_name
1815 (bfd *abfd, const char *templat, int *count);
1817 Invent a section name that is unique in ABFD by tacking a dot and a
1818 digit suffix onto the original TEMPLAT. If COUNT is non-NULL, then it
1819 specifies the first number tried as a suffix to generate a unique name.
1820 The value pointed to by COUNT will be incremented in this case.
1822 2.6.5.5 `bfd_make_section_old_way'
1823 ..................................
1826 asection *bfd_make_section_old_way (bfd *abfd, const char *name);
1828 Create a new empty section called NAME and attach it to the end of the
1829 chain of sections for the BFD ABFD. An attempt to create a section with
1830 a name which is already in use returns its pointer without changing the
1833 It has the funny name since this is the way it used to be before it
1836 Possible errors are:
1837 * `bfd_error_invalid_operation' - If output has already started for
1840 * `bfd_error_no_memory' - If memory allocation fails.
1842 2.6.5.6 `bfd_make_section_anyway_with_flags'
1843 ............................................
1846 asection *bfd_make_section_anyway_with_flags
1847 (bfd *abfd, const char *name, flagword flags);
1849 Create a new empty section called NAME and attach it to the end of the
1850 chain of sections for ABFD. Create a new section even if there is
1851 already a section with that name. Also set the attributes of the new
1852 section to the value FLAGS.
1854 Return `NULL' and set `bfd_error' on error; possible errors are:
1855 * `bfd_error_invalid_operation' - If output has already started for
1858 * `bfd_error_no_memory' - If memory allocation fails.
1860 2.6.5.7 `bfd_make_section_anyway'
1861 .................................
1864 asection *bfd_make_section_anyway (bfd *abfd, const char *name);
1866 Create a new empty section called NAME and attach it to the end of the
1867 chain of sections for ABFD. Create a new section even if there is
1868 already a section with that name.
1870 Return `NULL' and set `bfd_error' on error; possible errors are:
1871 * `bfd_error_invalid_operation' - If output has already started for
1874 * `bfd_error_no_memory' - If memory allocation fails.
1876 2.6.5.8 `bfd_make_section_with_flags'
1877 .....................................
1880 asection *bfd_make_section_with_flags
1881 (bfd *, const char *name, flagword flags);
1883 Like `bfd_make_section_anyway', but return `NULL' (without calling
1884 bfd_set_error ()) without changing the section chain if there is
1885 already a section named NAME. Also set the attributes of the new
1886 section to the value FLAGS. If there is an error, return `NULL' and set
1889 2.6.5.9 `bfd_make_section'
1890 ..........................
1893 asection *bfd_make_section (bfd *, const char *name);
1895 Like `bfd_make_section_anyway', but return `NULL' (without calling
1896 bfd_set_error ()) without changing the section chain if there is
1897 already a section named NAME. If there is an error, return `NULL' and
1900 2.6.5.10 `bfd_set_section_flags'
1901 ................................
1904 bfd_boolean bfd_set_section_flags
1905 (bfd *abfd, asection *sec, flagword flags);
1907 Set the attributes of the section SEC in the BFD ABFD to the value
1908 FLAGS. Return `TRUE' on success, `FALSE' on error. Possible error
1911 * `bfd_error_invalid_operation' - The section cannot have one or
1912 more of the attributes requested. For example, a .bss section in
1913 `a.out' may not have the `SEC_HAS_CONTENTS' field set.
1915 2.6.5.11 `bfd_map_over_sections'
1916 ................................
1919 void bfd_map_over_sections
1921 void (*func) (bfd *abfd, asection *sect, void *obj),
1924 Call the provided function FUNC for each section attached to the BFD
1925 ABFD, passing OBJ as an argument. The function will be called as if by
1927 func (abfd, the_section, obj);
1929 This is the preferred method for iterating over sections; an
1930 alternative would be to use a loop:
1933 for (p = abfd->sections; p != NULL; p = p->next)
1936 2.6.5.12 `bfd_sections_find_if'
1937 ...............................
1940 asection *bfd_sections_find_if
1942 bfd_boolean (*operation) (bfd *abfd, asection *sect, void *obj),
1945 Call the provided function OPERATION for each section attached to the
1946 BFD ABFD, passing OBJ as an argument. The function will be called as if
1949 operation (abfd, the_section, obj);
1951 It returns the first section for which OPERATION returns true.
1953 2.6.5.13 `bfd_set_section_size'
1954 ...............................
1957 bfd_boolean bfd_set_section_size
1958 (bfd *abfd, asection *sec, bfd_size_type val);
1960 Set SEC to the size VAL. If the operation is ok, then `TRUE' is
1961 returned, else `FALSE'.
1963 Possible error returns:
1964 * `bfd_error_invalid_operation' - Writing has started to the BFD, so
1965 setting the size is invalid.
1967 2.6.5.14 `bfd_set_section_contents'
1968 ...................................
1971 bfd_boolean bfd_set_section_contents
1972 (bfd *abfd, asection *section, const void *data,
1973 file_ptr offset, bfd_size_type count);
1975 Sets the contents of the section SECTION in BFD ABFD to the data
1976 starting in memory at DATA. The data is written to the output section
1977 starting at offset OFFSET for COUNT octets.
1979 Normally `TRUE' is returned, else `FALSE'. Possible error returns
1981 * `bfd_error_no_contents' - The output section does not have the
1982 `SEC_HAS_CONTENTS' attribute, so nothing can be written to it.
1985 This routine is front end to the back end function
1986 `_bfd_set_section_contents'.
1988 2.6.5.15 `bfd_get_section_contents'
1989 ...................................
1992 bfd_boolean bfd_get_section_contents
1993 (bfd *abfd, asection *section, void *location, file_ptr offset,
1994 bfd_size_type count);
1996 Read data from SECTION in BFD ABFD into memory starting at LOCATION.
1997 The data is read at an offset of OFFSET from the start of the input
1998 section, and is read for COUNT bytes.
2000 If the contents of a constructor with the `SEC_CONSTRUCTOR' flag set
2001 are requested or if the section does not have the `SEC_HAS_CONTENTS'
2002 flag set, then the LOCATION is filled with zeroes. If no errors occur,
2003 `TRUE' is returned, else `FALSE'.
2005 2.6.5.16 `bfd_malloc_and_get_section'
2006 .....................................
2009 bfd_boolean bfd_malloc_and_get_section
2010 (bfd *abfd, asection *section, bfd_byte **buf);
2012 Read all data from SECTION in BFD ABFD into a buffer, *BUF, malloc'd by
2015 2.6.5.17 `bfd_copy_private_section_data'
2016 ........................................
2019 bfd_boolean bfd_copy_private_section_data
2020 (bfd *ibfd, asection *isec, bfd *obfd, asection *osec);
2022 Copy private section information from ISEC in the BFD IBFD to the

2055 BFD tries to maintain as much symbol information as it can when it
2056 moves information from file to file. BFD passes information to
2057 applications though the `asymbol' structure. When the application
2058 requests the symbol table, BFD reads the table in the native form and
2059 translates parts of it into the internal format. To maintain more than
2060 the information passed to applications, some targets keep some
2061 information "behind the scenes" in a structure only the particular back
2062 end knows about. For example, the coff back end keeps the original
2063 symbol table structure as well as the canonical structure when a BFD is
2064 read in. On output, the coff back end can reconstruct the output symbol
2065 table so that no information is lost, even information unique to coff
2066 which BFD doesn't know or understand. If a coff symbol table were read,
2067 but were written through an a.out back end, all the coff specific
2068 information would be lost. The symbol table of a BFD is not necessarily
2069 read in until a canonicalize request is made. Then the BFD back end
2070 fills in a table provided by the application with pointers to the
2071 canonical information. To output symbols, the application provides BFD
2072 with a table of pointers to pointers to `asymbol's. This allows
2073 applications like the linker to output a symbol as it was read, since
2074 the "behind the scenes" information will be still available.

2087 2.7.1 Reading symbols
2088 ---------------------
2090 There are two stages to reading a symbol table from a BFD: allocating
2091 storage, and the actual reading process. This is an excerpt from an
2092 application which reads the symbol table:
2094 long storage_needed;
2095 asymbol **symbol_table;
2096 long number_of_symbols;
2099 storage_needed = bfd_get_symtab_upper_bound (abfd);
2101 if (storage_needed < 0)
2104 if (storage_needed == 0)
2107 symbol_table = xmalloc (storage_needed);
2110 bfd_canonicalize_symtab (abfd, symbol_table);
2112 if (number_of_symbols < 0)
2115 for (i = 0; i < number_of_symbols; i++)
2116 process_symbol (symbol_table[i]);
2118 All storage for the symbols themselves is in an objalloc connected
2119 to the BFD; it is freed when the BFD is closed.
2122 File: bfd.info, Node: Writing Symbols, Next: Mini Symbols, Prev: Reading Symbols, Up: Symbols
2124 2.7.2 Writing symbols
2125 ---------------------
2127 Writing of a symbol table is automatic when a BFD open for writing is
2128 closed. The application attaches a vector of pointers to pointers to
2129 symbols to the BFD being written, and fills in the symbol count. The
2130 close and cleanup code reads through the table provided and performs
2131 all the necessary operations. The BFD output code must always be
2132 provided with an "owned" symbol: one which has come from another BFD,
2133 or one which has been created using `bfd_make_empty_symbol'. Here is an
2134 example showing the creation of a symbol table with only one element:
2143 abfd = bfd_openw ("foo","a.out-sunos-big");
2144 bfd_set_format (abfd, bfd_object);
2145 new = bfd_make_empty_symbol (abfd);
2146 new->name = "dummy_symbol";
2147 new->section = bfd_make_section_old_way (abfd, ".text");
2148 new->flags = BSF_GLOBAL;
2149 new->value = 0x12345;
2154 bfd_set_symtab (abfd, ptrs, 1);
2161 00012345 A dummy_symbol
2163 Many formats cannot represent arbitrary symbol information; for
2164 instance, the `a.out' object format does not allow an arbitrary number
2165 of sections. A symbol pointing to a section which is not one of
2166 `.text', `.data' or `.bss' cannot be described.
2169 File: bfd.info, Node: Mini Symbols, Next: typedef asymbol, Prev: Writing Symbols, Up: Symbols
2174 Mini symbols provide read-only access to the symbol table. They use
2175 less memory space, but require more time to access. They can be useful
2176 for tools like nm or objdump, which may have to handle symbol tables of
2177 extremely large executables.
2179 The `bfd_read_minisymbols' function will read the symbols into
2180 memory in an internal form. It will return a `void *' pointer to a
2181 block of memory, a symbol count, and the size of each symbol. The
2182 pointer is allocated using `malloc', and should be freed by the caller
2183 when it is no longer needed.
2185 The function `bfd_minisymbol_to_symbol' will take a pointer to a
2186 minisymbol, and a pointer to a structure returned by
2187 `bfd_make_empty_symbol', and return a `asymbol' structure. The return
2188 value may or may not be the same as the value from
2189 `bfd_make_empty_symbol' which was passed in.

2490 An archive (or library) is just another BFD. It has a symbol table,
2491 although there's not much a user program will do with it.
2493 The big difference between an archive BFD and an ordinary BFD is
2494 that the archive doesn't have sections. Instead it has a chain of BFDs
2495 that are considered its contents. These BFDs can be manipulated like
2496 any other. The BFDs contained in an archive opened for reading will
2497 all be opened for reading. You may put either input or output BFDs
2498 into an archive opened for output; they will be handled correctly when
2499 the archive is closed.
2501 Use `bfd_openr_next_archived_file' to step through the contents of
2502 an archive opened for input. You don't have to read the entire archive
2503 if you don't want to! Read it until you find what you want.
2505 Archive contents of output BFDs are chained through the `next'
2506 pointer in a BFD. The first one is findable through the `archive_head'
2507 slot of the archive. Set it with `bfd_set_archive_head' (q.v.). A
2508 given BFD may be in only one open output archive at a time.
2510 As expected, the BFD archive code is more general than the archive
2511 code of any given environment. BFD archives may contain files of
2512 different formats (e.g., a.out and coff) and even different
2513 architectures. You may even place archives recursively into archives!
2515 This can cause unexpected confusion, since some archive formats are
2516 more expressive than others. For instance, Intel COFF archives can
2517 preserve long filenames; SunOS a.out archives cannot. If you move a
2518 file from the first to the second format and back again, the filename
2519 may be truncated. Likewise, different a.out environments have different
2520 conventions as to how they truncate filenames, whether they preserve
2521 directory names in filenames, etc. When interoperating with native
2522 tools, be sure your files are homogeneous.
2524 Beware: most of these formats do not react well to the presence of
2525 spaces in filenames. We do the best we can, but can't always handle
2526 this case due to restrictions in the format of archives. Many Unix
2527 utilities are braindead in regards to spaces and such in filenames
2528 anyway, so this shouldn't be much of a restriction.
2530 Archives are supported in BFD in `archive.c'.

2539 symindex bfd_get_next_mapent
2540 (bfd *abfd, symindex previous, carsym **sym);
2542 Step through archive ABFD's symbol table (if it has one). Successively
2543 update SYM with the next symbol's information, returning that symbol's
2544 (internal) index into the symbol table.
2546 Supply `BFD_NO_MORE_SYMBOLS' as the PREVIOUS entry to get the first
2547 one; returns `BFD_NO_MORE_SYMBOLS' when you've already got the last one.
2549 A `carsym' is a canonical archive symbol. The only user-visible
2550 element is its name, a null-terminated string.

2567 Provided a BFD, ARCHIVE, containing an archive and NULL, open an input
2568 BFD on the first contained element and returns that. Subsequent calls
2569 should pass the archive and the previous return value to return a
2570 created BFD to the next contained element. NULL is returned when there

2579 A format is a BFD concept of high level file contents type. The formats
2580 supported by BFD are:
2583 The BFD may contain data, symbols, relocations and debug info.
2586 The BFD contains other BFDs and an optional index.
2589 The BFD contains the result of an executable core dump.
2591 2.9.1 File format functions
2592 ---------------------------
2594 2.9.1.1 `bfd_check_format'
2595 ..........................
2598 bfd_boolean bfd_check_format (bfd *abfd, bfd_format format);
2600 Verify if the file attached to the BFD ABFD is compatible with the
2601 format FORMAT (i.e., one of `bfd_object', `bfd_archive' or `bfd_core').
2603 If the BFD has been set to a specific target before the call, only
2604 the named target and format combination is checked. If the target has
2605 not been set, or has been set to `default', then all the known target
2606 backends is interrogated to determine a match. If the default target
2607 matches, it is used. If not, exactly one target must recognize the
2608 file, or an error results.
2610 The function returns `TRUE' on success, otherwise `FALSE' with one
2611 of the following error codes:
2613 * `bfd_error_invalid_operation' - if `format' is not one of
2614 `bfd_object', `bfd_archive' or `bfd_core'.
2616 * `bfd_error_system_call' - if an error occured during a read - even
2617 some file mismatches can cause bfd_error_system_calls.
2619 * `file_not_recognised' - none of the backends recognised the file
2622 * `bfd_error_file_ambiguously_recognized' - more than one backend
2623 recognised the file format.
2625 2.9.1.2 `bfd_check_format_matches'
2626 ..................................
2629 bfd_boolean bfd_check_format_matches
2630 (bfd *abfd, bfd_format format, char ***matching);
2632 Like `bfd_check_format', except when it returns FALSE with `bfd_errno'
2633 set to `bfd_error_file_ambiguously_recognized'. In that case, if
2634 MATCHING is not NULL, it will be filled in with a NULL-terminated list
2635 of the names of the formats that matched, allocated with `malloc'.
2636 Then the user may choose a format and try again.
2638 When done with the list that MATCHING points to, the caller should
2641 2.9.1.3 `bfd_set_format'
2642 ........................
2645 bfd_boolean bfd_set_format (bfd *abfd, bfd_format format);
2647 This function sets the file format of the BFD ABFD to the format
2648 FORMAT. If the target set in the BFD does not support the format
2649 requested, the format is invalid, or the BFD is not open for writing,
2650 then an error occurs.
2652 2.9.1.4 `bfd_format_string'
2653 ...........................
2656 const char *bfd_format_string (bfd_format format);
2658 Return a pointer to a const string `invalid', `object', `archive',
2659 `core', or `unknown', depending upon the value of FORMAT.

2667 BFD maintains relocations in much the same way it maintains symbols:
2668 they are left alone until required, then read in en-masse and
2669 translated into an internal form. A common routine
2670 `bfd_perform_relocation' acts upon the canonical form to do the fixup.
2672 Relocations are maintained on a per section basis, while symbols are
2673 maintained on a per BFD basis.
2675 All that a back end has to do to fit the BFD interface is to create
2676 a `struct reloc_cache_entry' for each relocation in a particular

2690 This is the structure of a relocation entry:
2693 typedef enum bfd_reloc_status
2695 /* No errors detected. */
2698 /* The relocation was performed, but there was an overflow. */
2701 /* The address to relocate was not within the section supplied. */

2717 generated only when linking i960 coff files with i960 b.out
2718 symbols. If this type is returned, the error_message argument
2719 to bfd_perform_relocation will be set. */
2722 bfd_reloc_status_type;
2725 typedef struct reloc_cache_entry
2727 /* A pointer into the canonical table of pointers. */
2728 struct bfd_symbol **sym_ptr_ptr;
2730 /* offset in section. */
2731 bfd_size_type address;
2733 /* addend for relocation value. */
2736 /* Pointer to how to perform the required relocation. */
2737 reloc_howto_type *howto;
2742 Here is a description of each of the fields within an `arelent':
2745 The symbol table pointer points to a pointer to the symbol
2746 associated with the relocation request. It is the pointer into the
2747 table returned by the back end's `canonicalize_symtab' action. *Note
2748 Symbols::. The symbol is referenced through a pointer to a pointer so
2749 that tools like the linker can fix up all the symbols of the same name
2750 by modifying only one pointer. The relocation routine looks in the
2751 symbol and uses the base of the section the symbol is attached to and
2752 the value of the symbol as the initial relocation offset. If the symbol
2753 pointer is zero, then the section provided is looked up.
2756 The `address' field gives the offset in bytes from the base of the
2757 section data which owns the relocation record to the first byte of
2758 relocatable information. The actual data relocated will be relative to
2759 this point; for example, a relocation type which modifies the bottom
2760 two bytes of a four byte word would not touch the first byte pointed to
2761 in a big endian world.
2764 The `addend' is a value provided by the back end to be added (!) to
2765 the relocation offset. Its interpretation is dependent upon the howto.
2766 For example, on the 68k the code:
2771 return foo[0x12345678];
2774 Could be compiled into:
2782 This could create a reloc pointing to `foo', but leave the offset in
2783 the data, something like:
2785 RELOCATION RECORDS FOR [.text]:
2789 00000000 4e56 fffc ; linkw fp,#-4
2790 00000004 1039 1234 5678 ; moveb @#12345678,d0
2791 0000000a 49c0 ; extbl d0
2792 0000000c 4e5e ; unlk fp
2795 Using coff and an 88k, some instructions don't have enough space in
2796 them to represent the full address range, and pointers have to be
2797 loaded in two parts. So you'd get something like:
2799 or.u r13,r0,hi16(_foo+0x12345678)
2800 ld.b r2,r13,lo16(_foo+0x12345678)
2803 This should create two relocs, both pointing to `_foo', and with
2804 0x12340000 in their addend field. The data would consist of:
2806 RELOCATION RECORDS FOR [.text]:
2808 00000002 HVRT16 _foo+0x12340000
2809 00000006 LVRT16 _foo+0x12340000
2811 00000000 5da05678 ; or.u r13,r0,0x5678
2812 00000004 1c4d5678 ; ld.b r2,r13,0x5678
2813 00000008 f400c001 ; jmp r1
2815 The relocation routine digs out the value from the data, adds it to
2816 the addend to get the original offset, and then adds the value of
2817 `_foo'. Note that all 32 bits have to be kept around somewhere, to cope
2818 with carry from bit 15 to bit 16.
2820 One further example is the sparc and the a.out format. The sparc has
2821 a similar problem to the 88k, in that some instructions don't have room
2822 for an entire offset, but on the sparc the parts are created in odd
2823 sized lumps. The designers of the a.out format chose to not use the
2824 data within the section for storing part of the offset; all the offset
2825 is kept within the reloc. Anything in the data should be ignored.
2828 sethi %hi(_foo+0x12345678),%g2
2829 ldsb [%g2+%lo(_foo+0x12345678)],%i0
2833 Both relocs contain a pointer to `foo', and the offsets contain junk.
2835 RELOCATION RECORDS FOR [.text]:
2837 00000004 HI22 _foo+0x12345678
2838 00000008 LO10 _foo+0x12345678
2840 00000000 9de3bf90 ; save %sp,-112,%sp
2841 00000004 05000000 ; sethi %hi(_foo+0),%g2
2842 00000008 f048a000 ; ldsb [%g2+%lo(_foo+0)],%i0
2843 0000000c 81c7e008 ; ret
2844 00000010 81e80000 ; restore
2847 The `howto' field can be imagined as a relocation instruction. It is
2848 a pointer to a structure which contains information on what to do with
2849 all of the other information in the reloc record and data section. A
2850 back end would normally have a relocation instruction set and turn
2851 relocations into pointers to the correct structure on input - but it
2852 would be possible to create each howto field on demand.

2947 However, the converse is not true: not all relocations of all ELF

3014 2.10.1.4 `bfd_get_reloc_size'
3015 .............................
3018 unsigned int bfd_get_reloc_size (reloc_howto_type *);
3020 For a reloc_howto_type that operates on a fixed number of bytes, this
3021 returns the number of bytes operated on.

3039 bfd_reloc_status_type bfd_check_overflow
3040 (enum complain_overflow how,
3041 unsigned int bitsize,
3042 unsigned int rightshift,
3043 unsigned int addrsize,
3044 bfd_vma relocation);
3046 Perform overflow checking on RELOCATION which has BITSIZE significant
3047 bits and will be shifted right by RIGHTSHIFT bits, on a machine with
3048 addresses containing ADDRSIZE significant bits. The result is either of
3049 `bfd_reloc_ok' or `bfd_reloc_overflow'.
3051 2.10.1.7 `bfd_perform_relocation'
3052 .................................
3055 bfd_reloc_status_type bfd_perform_relocation
3057 arelent *reloc_entry,
3059 asection *input_section,
3061 char **error_message);
3063 If OUTPUT_BFD is supplied to this function, the generated image will be
3064 relocatable; the relocations are copied to the output file after they
3065 have been changed to reflect the new state of the world. There are two
3066 ways of reflecting the results of partial linkage in an output file: by
3067 modifying the output data in place, and by modifying the relocation
3068 record. Some native formats (e.g., basic a.out and basic coff) have no
3069 way of specifying an addend in the relocation type, so the addend has
3070 to go in the output data. This is no big deal since in these formats
3071 the output data slot will always be big enough for the addend. Complex
3072 reloc types with addends were invented to solve just this problem. The
3073 ERROR_MESSAGE argument is set to an error message if this return
3074 `bfd_reloc_dangerous'.
3076 2.10.1.8 `bfd_install_relocation'
3077 .................................
3080 bfd_reloc_status_type bfd_install_relocation
3082 arelent *reloc_entry,
3083 void *data, bfd_vma data_start,
3084 asection *input_section,
3085 char **error_message);
3087 This looks remarkably like `bfd_perform_relocation', except it does not
3088 expect that the section contents have been filled in. I.e., it's
3089 suitable for use when creating, rather than applying a relocation.
3091 For now, this function should be considered reserved for the

3097 2.10.2 The howto manager
3098 ------------------------
3100 When an application wants to create a relocation, but doesn't know what
3101 the target machine might call it, it can find out by using this bit of
3104 2.10.2.1 `bfd_reloc_code_type'
3105 ..............................
3108 The insides of a reloc code. The idea is that, eventually, there will
3109 be one enumerator for every type of relocation we ever do. Pass one of
3110 these values to `bfd_reloc_type_lookup', and it'll return a howto
3113 This does mean that the application must determine the correct
3114 enumerator value; you can't get a howto pointer from a random set of
3117 Here are the possible values for `enum bfd_reloc_code_real':

3303 Alpha ECOFF and ELF relocations. Some of these treat the symbol or
3304 "addend" in some special way. For GPDISP_HI16 ("gpdisp")
3305 relocations, the symbol is ignored when writing; when reading, it
3306 will be the absolute section symbol. The addend is the
3307 displacement in bytes of the "lda" instruction from the "ldah"
3308 instruction (which is at the address of this reloc).
3310 -- : BFD_RELOC_ALPHA_GPDISP_LO16
3311 For GPDISP_LO16 ("ignore") relocations, the symbol is handled as
3312 with GPDISP_HI16 relocs. The addend is ignored when writing the
3313 relocations out, and is filled in with the file's GP value on
3314 reading, for convenience.
3316 -- : BFD_RELOC_ALPHA_GPDISP
3317 The ELF GPDISP relocation is exactly the same as the GPDISP_HI16
3318 relocation except that there is no accompanying GPDISP_LO16
3321 -- : BFD_RELOC_ALPHA_LITERAL
3322 -- : BFD_RELOC_ALPHA_ELF_LITERAL
3323 -- : BFD_RELOC_ALPHA_LITUSE
3324 The Alpha LITERAL/LITUSE relocs are produced by a symbol reference;
3325 the assembler turns it into a LDQ instruction to load the address
3326 of the symbol, and then fills in a register in the real
3329 The LITERAL reloc, at the LDQ instruction, refers to the .lita
3330 section symbol. The addend is ignored when writing, but is filled
3331 in with the file's GP value on reading, for convenience, as with
3332 the GPDISP_LO16 reloc.
3334 The ELF_LITERAL reloc is somewhere between 16_GOTOFF and
3335 GPDISP_LO16. It should refer to the symbol to be referenced, as
3336 with 16_GOTOFF, but it generates output not based on the position
3337 within the .got section, but relative to the GP value chosen for
3338 the file during the final link stage.
3340 The LITUSE reloc, on the instruction using the loaded address,
3341 gives information to the linker that it might be able to use to
3342 optimize away some literal section references. The symbol is
3343 ignored (read as the absolute section symbol), and the "addend"
3344 indicates the type of instruction using the register: 1 - "memory"
3345 fmt insn 2 - byte-manipulation (byte offset reg) 3 - jsr (target
3348 -- : BFD_RELOC_ALPHA_HINT
3349 The HINT relocation indicates a value that should be filled into
3350 the "hint" field of a jmp/jsr/ret instruction, for possible branch-
3351 prediction logic which may be provided on some processors.
3353 -- : BFD_RELOC_ALPHA_LINKAGE
3354 The LINKAGE relocation outputs a linkage pair in the object file,
3355 which is filled by the linker.

3358 The CODEADDR relocation outputs a STO_CA in the object file, which
3359 is filled by the linker.

4676 the entries that are not used, so that the code for those
4677 functions need not be included in the output.
4679 VTABLE_INHERIT is a zero-space relocation used to describe to the
4680 linker the inheritance tree of a C++ virtual function table. The
4681 relocation's symbol should be the parent class' vtable, and the
4682 relocation should be located at the child vtable.
4684 VTABLE_ENTRY is a zero-space relocation that describes the use of a
4685 virtual function table entry. The reloc's symbol should refer to
4686 the table of the class mentioned in the code. Off of that base,
4687 an offset describes the entry that is being used. For Rela hosts,
4688 this offset is stored in the reloc's addend. For Rel hosts, we
4689 are forced to put this offset in the reloc's section offset.

5189 2.11.1 Core file functions
5190 --------------------------
5193 These are functions pertaining to core files.
5195 2.11.1.1 `bfd_core_file_failing_command'
5196 ........................................
5199 const char *bfd_core_file_failing_command (bfd *abfd);
5201 Return a read-only string explaining which program was running when it
5202 failed and produced the core file ABFD.
5204 2.11.1.2 `bfd_core_file_failing_signal'
5205 .......................................
5208 int bfd_core_file_failing_signal (bfd *abfd);
5210 Returns the signal number which caused the core dump which generated
5211 the file the BFD ABFD is attached to.
5213 2.11.1.3 `core_file_matches_executable_p'
5214 .........................................
5217 bfd_boolean core_file_matches_executable_p
5218 (bfd *core_bfd, bfd *exec_bfd);
5220 Return `TRUE' if the core file attached to CORE_BFD was generated by a
5221 run of the executable file attached to EXEC_BFD, `FALSE' otherwise.
5223 2.11.1.4 `generic_core_file_matches_executable_p'
5224 .................................................
5227 bfd_boolean generic_core_file_matches_executable_p
5228 (bfd *core_bfd, bfd *exec_bfd);
5230 Return TRUE if the core file attached to CORE_BFD was generated by a
5231 run of the executable file attached to EXEC_BFD. The match is based on
5232 executable basenames only.
5234 Note: When not able to determine the core file failing command or
5235 the executable name, we still return TRUE even though we're not sure
5236 that core file and executable match. This is to avoid generating a
5237 false warning in situations where we really don't know whether they
5241 File: bfd.info, Node: Targets, Next: Architectures, Prev: Core Files, Up: BFD front end
5247 Each port of BFD to a different machine requires the creation of a
5248 target back end. All the back end provides to the root part of BFD is a
5249 structure containing pointers to functions which perform certain low
5250 level operations on files. BFD translates the applications's requests
5251 through a pointer into calls to the back end routines.
5253 When a file is opened with `bfd_openr', its format and target are
5254 unknown. BFD uses various mechanisms to determine how to interpret the
5255 file. The operations performed are:
5257 * Create a BFD by calling the internal routine `_bfd_new_bfd', then
5258 call `bfd_find_target' with the target string supplied to
5259 `bfd_openr' and the new BFD pointer.
5261 * If a null target string was provided to `bfd_find_target', look up
5262 the environment variable `GNUTARGET' and use that as the target
5265 * If the target string is still `NULL', or the target string is
5266 `default', then use the first item in the target vector as the
5267 target type, and set `target_defaulted' in the BFD to cause
5268 `bfd_check_format' to loop through all the targets. *Note
5269 bfd_target::. *Note Formats::.
5271 * Otherwise, inspect the elements in the target vector one by one,
5272 until a match on target name is found. When found, use it.
5274 * Otherwise return the error `bfd_error_invalid_target' to
5277 * `bfd_openr' attempts to open the file using `bfd_open_file', and
5279 Once the BFD has been opened and the target selected, the file
5280 format may be determined. This is done by calling `bfd_check_format' on
5281 the BFD with a suggested format. If `target_defaulted' has been set,
5282 each possible target type is tried to see if it recognizes the
5283 specified format. `bfd_check_format' returns `TRUE' when the caller
5291 File: bfd.info, Node: bfd_target, Prev: Targets, Up: Targets
5297 This structure contains everything that BFD knows about a target. It
5298 includes things like its byte order, name, and which routines to call
5299 to do various operations.
5301 Every BFD points to a target structure with its `xvec' member.
5303 The macros below are used to dispatch to functions through the
5304 `bfd_target' vector. They are used in a number of macros further down
5305 in `bfd.h', and are also used when calling various routines by hand
5306 inside the BFD implementation. The ARGLIST argument must be
5307 parenthesized; it contains all the arguments to the called function.
5309 They make the documentation (more) unpleasant to read, so if someone
5310 wants to fix this and not break the above, please do.
5311 #define BFD_SEND(bfd, message, arglist) \
5312 ((*((bfd)->xvec->message)) arglist)
5314 #ifdef DEBUG_BFD_SEND
5316 #define BFD_SEND(bfd, message, arglist) \
5317 (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
5318 ((*((bfd)->xvec->message)) arglist) : \
5319 (bfd_assert (__FILE__,__LINE__), NULL))
5321 For operations which index on the BFD format:
5322 #define BFD_SEND_FMT(bfd, message, arglist) \
5323 (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist)
5325 #ifdef DEBUG_BFD_SEND
5327 #define BFD_SEND_FMT(bfd, message, arglist) \
5328 (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
5329 (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist) : \
5330 (bfd_assert (__FILE__,__LINE__), NULL))
5332 This is the structure which defines the type of BFD this is. The
5333 `xvec' member of the struct `bfd' itself points here. Each module that
5334 implements access to a different target under BFD, defines one of these.
5336 FIXME, these names should be rationalised with the names of the
5337 entry points which call them. Too bad we can't have one macro to define

5715 2.12.1.1 `bfd_set_default_target'
5716 .................................
5719 bfd_boolean bfd_set_default_target (const char *name);
5721 Set the default target vector to use when recognizing a BFD. This
5722 takes the name of the target, which may be a BFD target name or a
5723 configuration triplet.
5725 2.12.1.2 `bfd_find_target'
5726 ..........................
5729 const bfd_target *bfd_find_target (const char *target_name, bfd *abfd);
5731 Return a pointer to the transfer vector for the object target named
5732 TARGET_NAME. If TARGET_NAME is `NULL', choose the one in the
5733 environment variable `GNUTARGET'; if that is null or not defined, then
5734 choose the first entry in the target list. Passing in the string
5735 "default" or setting the environment variable to "default" will cause
5736 the first entry in the target list to be returned, and
5737 "target_defaulted" will be set in the BFD if ABFD isn't `NULL'. This
5738 causes `bfd_check_format' to loop over all the targets to find the one
5739 that matches the file being read.
5741 2.12.1.3 `bfd_target_list'
5742 ..........................
5745 const char ** bfd_target_list (void);
5747 Return a freshly malloced NULL-terminated vector of the names of all
5748 the valid BFD targets. Do not modify the names.
5750 2.12.1.4 `bfd_seach_for_target'
5751 ...............................
5754 const bfd_target *bfd_search_for_target
5755 (int (*search_func) (const bfd_target *, void *),
5758 Return a pointer to the first transfer vector in the list of transfer
5759 vectors maintained by BFD that produces a non-zero result when passed
5760 to the function SEARCH_FUNC. The parameter DATA is passed, unexamined,
5761 to the search function.
5764 File: bfd.info, Node: Architectures, Next: Opening and Closing, Prev: Targets, Up: BFD front end
5769 BFD keeps one atom in a BFD describing the architecture of the data
5770 attached to the BFD: a pointer to a `bfd_arch_info_type'.
5772 Pointers to structures can be requested independently of a BFD so
5773 that an architecture's information can be interrogated without access
5776 The architecture information is provided by each architecture
5777 package. The set of default architectures is selected by the macro
5778 `SELECT_ARCHITECTURES'. This is normally set up in the
5779 `config/TARGET.mt' file of your choice. If the name is not defined,
5780 then all the architectures supported are included.
5782 When BFD starts up, all the architectures are called with an
5783 initialize method. It is up to the architecture back end to insert as
5784 many items into the list of architectures as it wants to; generally
5785 this would be one for each machine and one for the default case (an
5786 item with a machine field of 0).
5788 BFD's idea of an architecture is implemented in `archures.c'.
5790 2.13.1 bfd_architecture
5791 -----------------------
5794 This enum gives the object file's CPU architecture, in a global
5795 sense--i.e., what processor family does it belong to? Another field
5796 indicates which processor within the family is in use. The machine
5797 gives a number which distinguishes different versions of the
5798 architecture, containing, for example, 2 and 3 for Intel i960 KA and
5799 i960 KB, and 68020 and 68030 for Motorola 68020 and 68030.

6192 ..................................
6195 The `bfd_default_arch_struct' is an item of `bfd_arch_info_type' which
6196 has been initialized to a fairly generic state. A BFD starts life by
6197 pointing to this structure, until the correct back end has determined
6198 the real architecture of the file.

6273 .............................
6276 const bfd_arch_info_type *bfd_get_arch_info (bfd *abfd);
6278 Return the architecture info struct in ABFD.
6280 2.13.2.15 `bfd_lookup_arch'
6281 ...........................
6284 const bfd_arch_info_type *bfd_lookup_arch
6285 (enum bfd_architecture arch, unsigned long machine);
6287 Look for the architecture info structure which matches the arguments
6288 ARCH and MACHINE. A machine of 0 matches the machine/architecture

6301 This routine is depreciated.
6303 2.13.2.17 `bfd_octets_per_byte'
6304 ...............................
6307 unsigned int bfd_octets_per_byte (bfd *abfd);
6309 Return the number of octets (8-bit quantities) per target byte (minimum
6310 addressable unit). In most cases, this will be one, but some DSP
6311 targets have 16, 32, or even 48 bits per byte.

6328 2.14 Opening and closing BFDs
6329 =============================
6331 2.14.1 Functions for opening and closing
6332 ----------------------------------------
6334 2.14.1.1 `bfd_fopen'
6335 ....................
6338 bfd *bfd_fopen (const char *filename, const char *target,
6339 const char *mode, int fd);
6341 Open the file FILENAME with the target TARGET. Return a pointer to the
6342 created BFD. If FD is not -1, then `fdopen' is used to open the file;
6343 otherwise, `fopen' is used. MODE is passed directly to `fopen' or
6346 Calls `bfd_find_target', so TARGET is interpreted as by that
6349 The new BFD is marked as cacheable iff FD is -1.
6351 If `NULL' is returned then an error has occured. Possible errors
6352 are `bfd_error_no_memory', `bfd_error_invalid_target' or `system_call'
6355 2.14.1.2 `bfd_openr'
6356 ....................
6359 bfd *bfd_openr (const char *filename, const char *target);
6361 Open the file FILENAME (using `fopen') with the target TARGET. Return
6362 a pointer to the created BFD.
6364 Calls `bfd_find_target', so TARGET is interpreted as by that
6367 If `NULL' is returned then an error has occured. Possible errors
6368 are `bfd_error_no_memory', `bfd_error_invalid_target' or `system_call'
6371 2.14.1.3 `bfd_fdopenr'
6372 ......................
6375 bfd *bfd_fdopenr (const char *filename, const char *target, int fd);
6377 `bfd_fdopenr' is to `bfd_fopenr' much like `fdopen' is to `fopen'. It
6378 opens a BFD on a file already described by the FD supplied.
6380 When the file is later `bfd_close'd, the file descriptor will be
6381 closed. If the caller desires that this file descriptor be cached by
6382 BFD (opened as needed, closed as needed to free descriptors for other
6383 opens), with the supplied FD used as an initial file descriptor (but
6384 subject to closure at any time), call bfd_set_cacheable(bfd, 1) on the
6385 returned BFD. The default is to assume no caching; the file descriptor
6386 will remain open until `bfd_close', and will not be affected by BFD
6387 operations on other files.
6389 Possible errors are `bfd_error_no_memory',
6390 `bfd_error_invalid_target' and `bfd_error_system_call'.
6392 2.14.1.4 `bfd_openstreamr'
6393 ..........................
6396 bfd *bfd_openstreamr (const char *, const char *, void *);
6398 Open a BFD for read access on an existing stdio stream. When the BFD
6399 is passed to `bfd_close', the stream will be closed.
6401 2.14.1.5 `bfd_openr_iovec'
6402 ..........................
6405 bfd *bfd_openr_iovec (const char *filename, const char *target,
6406 void *(*open) (struct bfd *nbfd,
6407 void *open_closure),
6409 file_ptr (*pread) (struct bfd *nbfd,
6414 int (*close) (struct bfd *nbfd,
6417 Create and return a BFD backed by a read-only STREAM. The STREAM is
6418 created using OPEN, accessed using PREAD and destroyed using CLOSE.
6420 Calls `bfd_find_target', so TARGET is interpreted as by that
6423 Calls OPEN (which can call `bfd_zalloc' and `bfd_get_filename') to
6424 obtain the read-only stream backing the BFD. OPEN either succeeds
6425 returning the non-`NULL' STREAM, or fails returning `NULL' (setting
6428 Calls PREAD to request NBYTES of data from STREAM starting at OFFSET
6429 (e.g., via a call to `bfd_read'). PREAD either succeeds returning the
6430 number of bytes read (which can be less than NBYTES when end-of-file),
6431 or fails returning -1 (setting `bfd_error').
6433 Calls CLOSE when the BFD is later closed using `bfd_close'. CLOSE
6434 either succeeds returning 0, or fails returning -1 (setting
6437 If `bfd_openr_iovec' returns `NULL' then an error has occurred.
6438 Possible errors are `bfd_error_no_memory', `bfd_error_invalid_target'
6439 and `bfd_error_system_call'.
6441 2.14.1.6 `bfd_openw'
6442 ....................
6445 bfd *bfd_openw (const char *filename, const char *target);
6447 Create a BFD, associated with file FILENAME, using the file format
6448 TARGET, and return a pointer to it.
6450 Possible errors are `bfd_error_system_call', `bfd_error_no_memory',
6451 `bfd_error_invalid_target'.
6453 2.14.1.7 `bfd_close'
6454 ....................
6457 bfd_boolean bfd_close (bfd *abfd);
6459 Close a BFD. If the BFD was open for writing, then pending operations
6460 are completed and the file written out and closed. If the created file
6461 is executable, then `chmod' is called to mark it as such.
6463 All memory attached to the BFD is released.
6465 The file descriptor associated with the BFD is closed (even if it
6466 was passed in to BFD by `bfd_fdopenr').
6469 `TRUE' is returned if all is ok, otherwise `FALSE'.
6471 2.14.1.8 `bfd_close_all_done'
6472 .............................
6475 bfd_boolean bfd_close_all_done (bfd *);
6477 Close a BFD. Differs from `bfd_close' since it does not complete any
6478 pending operations. This routine would be used if the application had
6479 just used BFD for swapping and didn't want to use any of the writing
6482 If the created file is executable, then `chmod' is called to mark it
6485 All memory attached to the BFD is released.
6488 `TRUE' is returned if all is ok, otherwise `FALSE'.
6490 2.14.1.9 `bfd_create'
6491 .....................
6494 bfd *bfd_create (const char *filename, bfd *templ);
6496 Create a new BFD in the manner of `bfd_openw', but without opening a
6497 file. The new BFD takes the target from the target used by TEMPLATE.
6498 The format is always set to `bfd_object'.
6500 2.14.1.10 `bfd_make_writable'
6501 .............................
6504 bfd_boolean bfd_make_writable (bfd *abfd);
6506 Takes a BFD as created by `bfd_create' and converts it into one like as
6507 returned by `bfd_openw'. It does this by converting the BFD to
6508 BFD_IN_MEMORY. It's assumed that you will call `bfd_make_readable' on
6512 `TRUE' is returned if all is ok, otherwise `FALSE'.
6514 2.14.1.11 `bfd_make_readable'
6515 .............................
6518 bfd_boolean bfd_make_readable (bfd *abfd);
6520 Takes a BFD as created by `bfd_create' and `bfd_make_writable' and
6521 converts it into one like as returned by `bfd_openr'. It does this by
6522 writing the contents out to the memory buffer, then reversing the
6526 `TRUE' is returned if all is ok, otherwise `FALSE'.
6528 2.14.1.12 `bfd_alloc'
6529 .....................
6532 void *bfd_alloc (bfd *abfd, bfd_size_type wanted);
6534 Allocate a block of WANTED bytes of memory attached to `abfd' and
6535 return a pointer to it.
6537 2.14.1.13 `bfd_alloc2'
6538 ......................
6541 void *bfd_alloc2 (bfd *abfd, bfd_size_type nmemb, bfd_size_type size);
6543 Allocate a block of NMEMB elements of SIZE bytes each of memory
6544 attached to `abfd' and return a pointer to it.
6546 2.14.1.14 `bfd_zalloc'
6547 ......................
6550 void *bfd_zalloc (bfd *abfd, bfd_size_type wanted);
6552 Allocate a block of WANTED bytes of zeroed memory attached to `abfd'
6553 and return a pointer to it.
6555 2.14.1.15 `bfd_zalloc2'
6556 .......................
6559 void *bfd_zalloc2 (bfd *abfd, bfd_size_type nmemb, bfd_size_type size);
6561 Allocate a block of NMEMB elements of SIZE bytes each of zeroed memory
6562 attached to `abfd' and return a pointer to it.
6564 2.14.1.16 `bfd_calc_gnu_debuglink_crc32'
6565 ........................................
6568 unsigned long bfd_calc_gnu_debuglink_crc32
6569 (unsigned long crc, const unsigned char *buf, bfd_size_type len);
6571 Computes a CRC value as used in the .gnu_debuglink section. Advances
6572 the previously computed CRC value by computing and adding in the crc32
6573 for LEN bytes of BUF.
6576 Return the updated CRC32 value.
6578 2.14.1.17 `get_debug_link_info'
6579 ...............................
6582 char *get_debug_link_info (bfd *abfd, unsigned long *crc32_out);
6584 fetch the filename and CRC32 value for any separate debuginfo
6585 associated with ABFD. Return NULL if no such info found, otherwise
6586 return filename and update CRC32_OUT.
6588 2.14.1.18 `separate_debug_file_exists'
6589 ......................................
6592 bfd_boolean separate_debug_file_exists
6593 (char *name, unsigned long crc32);
6595 Checks to see if NAME is a file and if its contents match CRC32.
6597 2.14.1.19 `find_separate_debug_file'
6598 ....................................
6601 char *find_separate_debug_file (bfd *abfd);
6603 Searches ABFD for a reference to separate debugging information, scans
6604 various locations in the filesystem, including the file tree rooted at
6605 DEBUG_FILE_DIRECTORY, and returns a filename of such debugging
6606 information if the file is found and has matching CRC32. Returns NULL
6607 if no reference to debugging file exists, or file cannot be found.
6609 2.14.1.20 `bfd_follow_gnu_debuglink'
6610 ....................................
6613 char *bfd_follow_gnu_debuglink (bfd *abfd, const char *dir);
6615 Takes a BFD and searches it for a .gnu_debuglink section. If this
6616 section is found, it examines the section for the name and checksum of
6617 a '.debug' file containing auxiliary debugging information. It then
6618 searches the filesystem for this .debug file in some standard
6619 locations, including the directory tree rooted at DIR, and if found
6620 returns the full filename.
6622 If DIR is NULL, it will search a default path configured into libbfd
6623 at build time. [XXX this feature is not currently implemented].
6626 `NULL' on any errors or failure to locate the .debug file, otherwise a
6627 pointer to a heap-allocated string containing the filename. The caller
6628 is responsible for freeing this string.
6630 2.14.1.21 `bfd_create_gnu_debuglink_section'
6631 ............................................
6634 struct bfd_section *bfd_create_gnu_debuglink_section
6635 (bfd *abfd, const char *filename);
6637 Takes a BFD and adds a .gnu_debuglink section to it. The section is
6638 sized to be big enough to contain a link to the specified FILENAME.
6641 A pointer to the new section is returned if all is ok. Otherwise
6642 `NULL' is returned and bfd_error is set.
6644 2.14.1.22 `bfd_fill_in_gnu_debuglink_section'
6645 .............................................
6648 bfd_boolean bfd_fill_in_gnu_debuglink_section
6649 (bfd *abfd, struct bfd_section *sect, const char *filename);
6651 Takes a BFD and containing a .gnu_debuglink section SECT and fills in
6652 the contents of the section to contain a link to the specified
6653 FILENAME. The filename should be relative to the current directory.
6656 `TRUE' is returned if all is ok. Otherwise `FALSE' is returned and

6662 2.15 Implementation details
6663 ===========================
6665 2.15.1 Internal functions
6666 -------------------------
6669 These routines are used within BFD. They are not intended for export,
6670 but are documented here for completeness.
6672 2.15.1.1 `bfd_write_bigendian_4byte_int'
6673 ........................................
6676 bfd_boolean bfd_write_bigendian_4byte_int (bfd *, unsigned int);
6678 Write a 4 byte integer I to the output BFD ABFD, in big endian order
6679 regardless of what else is going on. This is useful in archives.
6681 2.15.1.2 `bfd_put_size'
6682 .......................
6684 2.15.1.3 `bfd_get_size'
6685 .......................
6688 These macros as used for reading and writing raw data in sections; each
6689 access (except for bytes) is vectored through the target format of the
6690 BFD and mangled accordingly. The mangling performs any necessary endian
6691 translations and removes alignment restrictions. Note that types
6692 accepted and returned by these macros are identical so they can be
6693 swapped around in macros--for example, `libaout.h' defines `GET_WORD'
6694 to either `bfd_get_32' or `bfd_get_64'.
6696 In the put routines, VAL must be a `bfd_vma'. If we are on a system
6697 without prototypes, the caller is responsible for making sure that is
6698 true, with a cast if necessary. We don't cast them in the macro
6699 definitions because that would prevent `lint' or `gcc -Wall' from
6700 detecting sins such as passing a pointer. To detect calling these with
6701 less than a `bfd_vma', use `gcc -Wconversion' on a host with 64 bit
6704 /* Byte swapping macros for user section data. */

6838 The file caching mechanism is embedded within BFD and allows the
6839 application to open as many BFDs as it wants without regard to the
6840 underlying operating system's file descriptor limit (often as low as 20
6841 open files). The module in `cache.c' maintains a least recently used
6842 list of `BFD_CACHE_MAX_OPEN' files, and exports the name
6843 `bfd_cache_lookup', which runs around and makes sure that the required
6844 BFD is open. If not, then it chooses a file to close, closes it and
6845 opens the one wanted, returning its file handle.

6899 2.17 Linker Functions
6900 =====================
6902 The linker uses three special entry points in the BFD target vector.
6903 It is not necessary to write special routines for these entry points
6904 when creating a new BFD back end, since generic versions are provided.
6905 However, writing them can speed up linking and make it use
6906 significantly less runtime memory.
6908 The first routine creates a hash table used by the other routines.
6909 The second routine adds the symbols from an object file to the hash
6910 table. The third routine takes all the object files and links them
6911 together to create the output file. These routines are designed so
6912 that the linker proper does not need to know anything about the symbols
6913 in the object files that it is linking. The linker merely arranges the
6914 sections as directed by the linker script and lets BFD handle the
6915 details of symbols and relocs.
6917 The second routine and third routines are passed a pointer to a
6918 `struct bfd_link_info' structure (defined in `bfdlink.h') which holds
6919 information relevant to the link, including the linker hash table
6920 (which was created by the first routine) and a set of callback
6921 functions to the linker proper.
6923 The generic linker routines are in `linker.c', and use the header
6924 file `genlink.h'. As of this writing, the only back ends which have
6925 implemented versions of these routines are a.out (in `aoutx.h') and
6926 ECOFF (in `ecoff.c'). The a.out routines are used as examples
6927 throughout this section.

6938 2.17.1 Creating a linker hash table
6939 -----------------------------------
6941 The linker routines must create a hash table, which must be derived
6942 from `struct bfd_link_hash_table' described in `bfdlink.c'. *Note Hash
6943 Tables::, for information on how to create a derived hash table. This
6944 entry point is called using the target vector of the linker output file.
6946 The `_bfd_link_hash_table_create' entry point must allocate and
6947 initialize an instance of the desired hash table. If the back end does
6948 not require any additional information to be stored with the entries in
6949 the hash table, the entry point may simply create a `struct
6950 bfd_link_hash_table'. Most likely, however, some additional
6951 information will be needed.
6953 For example, with each entry in the hash table the a.out linker
6954 keeps the index the symbol has in the final output file (this index
6955 number is used so that when doing a relocatable link the symbol index
6956 used in the output file can be quickly filled in when copying over a
6957 reloc). The a.out linker code defines the required structures and
6958 functions for a hash table derived from `struct bfd_link_hash_table'.
6959 The a.out linker hash table is created by the function
6960 `NAME(aout,link_hash_table_create)'; it simply allocates space for the
6961 hash table, initializes it, and returns a pointer to it.
6963 When writing the linker routines for a new back end, you will
6964 generally not know exactly which fields will be required until you have
6965 finished. You should simply create a new hash table which defines no
6966 additional fields, and then simply add fields as they become necessary.

6971 2.17.2 Adding symbols to the hash table
6972 ---------------------------------------
6974 The linker proper will call the `_bfd_link_add_symbols' entry point for
6975 each object file or archive which is to be linked (typically these are
6976 the files named on the command line, but some may also come from the
6977 linker script). The entry point is responsible for examining the file.
6978 For an object file, BFD must add any relevant symbol information to
6979 the hash table. For an archive, BFD must determine which elements of
6980 the archive should be used and adding them to the link.
6982 The a.out version of this entry point is
6983 `NAME(aout,link_add_symbols)'.

6989 * Adding symbols from an archive::
6992 File: bfd.info, Node: Differing file formats, Next: Adding symbols from an object file, Prev: Adding Symbols to the Hash Table, Up: Adding Symbols to the Hash Table
6994 2.17.2.1 Differing file formats
6995 ...............................
6997 Normally all the files involved in a link will be of the same format,
6998 but it is also possible to link together different format object files,
6999 and the back end must support that. The `_bfd_link_add_symbols' entry
7000 point is called via the target vector of the file to be added. This
7001 has an important consequence: the function may not assume that the hash
7002 table is the type created by the corresponding
7003 `_bfd_link_hash_table_create' vector. All the `_bfd_link_add_symbols'
7004 function can assume about the hash table is that it is derived from
7005 `struct bfd_link_hash_table'.
7007 Sometimes the `_bfd_link_add_symbols' function must store some
7008 information in the hash table entry to be used by the `_bfd_final_link'
7009 function. In such a case the `creator' field of the hash table must be
7010 checked to make sure that the hash table was created by an object file
7013 The `_bfd_final_link' routine must be prepared to handle a hash
7014 entry without any extra information added by the
7015 `_bfd_link_add_symbols' function. A hash entry without extra
7016 information will also occur when the linker script directs the linker
7017 to create a symbol. Note that, regardless of how a hash table entry is
7018 added, all the fields will be initialized to some sort of null value by
7019 the hash table entry initialization function.
7021 See `ecoff_link_add_externals' for an example of how to check the
7022 `creator' field before saving information (in this case, the ECOFF
7023 external symbol debugging information) in a hash table entry.

7028 2.17.2.2 Adding symbols from an object file
7029 ...........................................
7031 When the `_bfd_link_add_symbols' routine is passed an object file, it
7032 must add all externally visible symbols in that object file to the hash
7033 table. The actual work of adding the symbol to the hash table is
7034 normally handled by the function `_bfd_generic_link_add_one_symbol'.
7035 The `_bfd_link_add_symbols' routine is responsible for reading all the
7036 symbols from the object file and passing the correct information to
7037 `_bfd_generic_link_add_one_symbol'.
7039 The `_bfd_link_add_symbols' routine should not use
7040 `bfd_canonicalize_symtab' to read the symbols. The point of providing
7041 this routine is to avoid the overhead of converting the symbols into
7042 generic `asymbol' structures.
7044 `_bfd_generic_link_add_one_symbol' handles the details of combining
7045 common symbols, warning about multiple definitions, and so forth. It
7046 takes arguments which describe the symbol to add, notably symbol flags,
7047 a section, and an offset. The symbol flags include such things as
7048 `BSF_WEAK' or `BSF_INDIRECT'. The section is a section in the object
7049 file, or something like `bfd_und_section_ptr' for an undefined symbol
7050 or `bfd_com_section_ptr' for a common symbol.
7052 If the `_bfd_final_link' routine is also going to need to read the
7053 symbol information, the `_bfd_link_add_symbols' routine should save it
7054 somewhere attached to the object file BFD. However, the information
7055 should only be saved if the `keep_memory' field of the `info' argument
7056 is TRUE, so that the `-no-keep-memory' linker switch is effective.
7058 The a.out function which adds symbols from an object file is
7059 `aout_link_add_object_symbols', and most of the interesting work is in
7060 `aout_link_add_symbols'. The latter saves pointers to the hash tables
7061 entries created by `_bfd_generic_link_add_one_symbol' indexed by symbol
7062 number, so that the `_bfd_final_link' routine does not have to call the
7063 hash table lookup routine to locate the entry.
7066 File: bfd.info, Node: Adding symbols from an archive, Prev: Adding symbols from an object file, Up: Adding Symbols to the Hash Table
7068 2.17.2.3 Adding symbols from an archive
7069 .......................................
7071 When the `_bfd_link_add_symbols' routine is passed an archive, it must
7072 look through the symbols defined by the archive and decide which
7073 elements of the archive should be included in the link. For each such
7074 element it must call the `add_archive_element' linker callback, and it
7075 must add the symbols from the object file to the linker hash table.
7077 In most cases the work of looking through the symbols in the archive
7078 should be done by the `_bfd_generic_link_add_archive_symbols' function.
7079 This function builds a hash table from the archive symbol table and
7080 looks through the list of undefined symbols to see which elements
7081 should be included. `_bfd_generic_link_add_archive_symbols' is passed
7082 a function to call to make the final decision about adding an archive
7083 element to the link and to do the actual work of adding the symbols to
7084 the linker hash table.
7086 The function passed to `_bfd_generic_link_add_archive_symbols' must
7087 read the symbols of the archive element and decide whether the archive
7088 element should be included in the link. If the element is to be
7089 included, the `add_archive_element' linker callback routine must be
7090 called with the element as an argument, and the elements symbols must
7091 be added to the linker hash table just as though the element had itself
7092 been passed to the `_bfd_link_add_symbols' function.
7094 When the a.out `_bfd_link_add_symbols' function receives an archive,
7095 it calls `_bfd_generic_link_add_archive_symbols' passing
7096 `aout_link_check_archive_element' as the function argument.
7097 `aout_link_check_archive_element' calls `aout_link_check_ar_symbols'.
7098 If the latter decides to add the element (an element is only added if
7099 it provides a real, non-common, definition for a previously undefined
7100 or common symbol) it calls the `add_archive_element' callback and then
7101 `aout_link_check_archive_element' calls `aout_link_add_symbols' to
7102 actually add the symbols to the linker hash table.
7104 The ECOFF back end is unusual in that it does not normally call
7105 `_bfd_generic_link_add_archive_symbols', because ECOFF archives already
7106 contain a hash table of symbols. The ECOFF back end searches the
7107 archive itself to avoid the overhead of creating a new hash table.

7112 2.17.3 Performing the final link
7113 --------------------------------
7115 When all the input files have been processed, the linker calls the
7116 `_bfd_final_link' entry point of the output BFD. This routine is
7117 responsible for producing the final output file, which has several
7118 aspects. It must relocate the contents of the input sections and copy
7119 the data into the output sections. It must build an output symbol
7120 table including any local symbols from the input files and the global
7121 symbols from the hash table. When producing relocatable output, it must
7122 modify the input relocs and write them into the output file. There may
7123 also be object format dependent work to be done.
7125 The linker will also call the `write_object_contents' entry point
7126 when the BFD is closed. The two entry points must work together in
7127 order to produce the correct output file.
7129 The details of how this works are inevitably dependent upon the
7130 specific object file format. The a.out `_bfd_final_link' routine is
7131 `NAME(aout,final_link)'.

7145 Before the linker calls the `_bfd_final_link' entry point, it sets up
7146 some data structures for the function to use.
7148 The `input_bfds' field of the `bfd_link_info' structure will point
7149 to a list of all the input files included in the link. These files are
7150 linked through the `link_next' field of the `bfd' structure.
7152 Each section in the output file will have a list of `link_order'
7153 structures attached to the `map_head.link_order' field (the
7154 `link_order' structure is defined in `bfdlink.h'). These structures
7155 describe how to create the contents of the output section in terms of
7156 the contents of various input sections, fill constants, and,
7157 eventually, other types of information. They also describe relocs that
7158 must be created by the BFD backend, but do not correspond to any input
7159 file; this is used to support -Ur, which builds constructors while
7160 generating a relocatable object file.

7165 2.17.3.2 Relocating the section contents
7166 ........................................
7168 The `_bfd_final_link' function should look through the `link_order'
7169 structures attached to each section of the output file. Each
7170 `link_order' structure should either be handled specially, or it should
7171 be passed to the function `_bfd_default_link_order' which will do the
7172 right thing (`_bfd_default_link_order' is defined in `linker.c').
7174 For efficiency, a `link_order' of type `bfd_indirect_link_order'
7175 whose associated section belongs to a BFD of the same format as the
7176 output BFD must be handled specially. This type of `link_order'
7177 describes part of an output section in terms of a section belonging to
7178 one of the input files. The `_bfd_final_link' function should read the
7179 contents of the section and any associated relocs, apply the relocs to
7180 the section contents, and write out the modified section contents. If
7181 performing a relocatable link, the relocs themselves must also be
7182 modified and written out.
7184 The functions `_bfd_relocate_contents' and
7185 `_bfd_final_link_relocate' provide some general support for performing
7186 the actual relocations, notably overflow checking. Their arguments
7187 include information about the symbol the relocation is against and a
7188 `reloc_howto_type' argument which describes the relocation to perform.
7189 These functions are defined in `reloc.c'.
7191 The a.out function which handles reading, relocating, and writing
7192 section contents is `aout_link_input_section'. The actual relocation
7193 is done in `aout_link_input_section_std' and
7194 `aout_link_input_section_ext'.

7205 `discard' fields of the `bfd_link_info' structure.
7207 The local symbols of the input files will not have been entered into
7208 the linker hash table. The `_bfd_final_link' routine must consider
7209 each input file and include the symbols in the output file. It may be
7210 convenient to do this when looking through the `link_order' structures,
7211 or it may be done by stepping through the `input_bfds' list.
7213 The `_bfd_final_link' routine must also traverse the global hash
7214 table to gather all the externally visible symbols. It is possible
7215 that most of the externally visible symbols may be written out when
7216 considering the symbols of each input file, but it is still necessary
7217 to traverse the hash table since the linker script may have defined
7218 some symbols that are not in any of the input files.
7220 The `strip' field of the `bfd_link_info' structure controls which
7221 symbols are written out. The possible values are listed in
7222 `bfdlink.h'. If the value is `strip_some', then the `keep_hash' field
7223 of the `bfd_link_info' structure is a hash table of symbols to keep;
7224 each symbol should be looked up in this hash table, and only symbols
7225 which are present should be included in the output file.
7227 If the `strip' field of the `bfd_link_info' structure permits local
7228 symbols to be written out, the `discard' field is used to further
7229 controls which local symbols are included in the output file. If the
7230 value is `discard_l', then all local symbols which begin with a certain
7231 prefix are discarded; this is controlled by the
7232 `bfd_is_local_label_name' entry point.
7234 The a.out backend handles symbols by calling
7235 `aout_link_write_symbols' on each input BFD and then traversing the
7236 global hash table with the function `aout_link_write_other_symbol'. It
7237 builds a string table while writing out the symbols, which is written
7238 to the output file at the end of `NAME(aout,final_link)'.

7269 BFD provides a simple set of hash table functions. Routines are
7270 provided to initialize a hash table, to free a hash table, to look up a
7271 string in a hash table and optionally create an entry for it, and to
7272 traverse a hash table. There is currently no routine to delete an
7273 string from a hash table.
7275 The basic hash table does not permit any data to be stored with a
7276 string. However, a hash table is designed to present a base class from
7277 which other types of hash tables may be derived. These derived types
7278 may store additional information with the string. Hash tables were
7279 implemented in this way, rather than simply providing a data pointer in
7280 a hash table entry, because they were designed for use by the linker
7281 back ends. The linker may create thousands of hash table entries, and
7282 the overhead of allocating private data and storing and following
7283 pointers becomes noticeable.
7285 The basic hash table code is in `hash.c'.

7297 2.18.1 Creating and freeing a hash table
7298 ----------------------------------------
7300 To create a hash table, create an instance of a `struct bfd_hash_table'
7301 (defined in `bfd.h') and call `bfd_hash_table_init' (if you know
7302 approximately how many entries you will need, the function
7303 `bfd_hash_table_init_n', which takes a SIZE argument, may be used).
7304 `bfd_hash_table_init' returns `FALSE' if some sort of error occurs.
7306 The function `bfd_hash_table_init' take as an argument a function to
7307 use to create new entries. For a basic hash table, use the function
7308 `bfd_hash_newfunc'. *Note Deriving a New Hash Table Type::, for why
7309 you would want to use a different value for this argument.
7311 `bfd_hash_table_init' will create an objalloc which will be used to
7312 allocate new entries. You may allocate memory on this objalloc using
7313 `bfd_hash_allocate'.
7315 Use `bfd_hash_table_free' to free up all the memory that has been
7316 allocated for a hash table. This will not free up the `struct
7317 bfd_hash_table' itself, which you must provide.
7319 Use `bfd_hash_set_default_size' to set the default size of hash

7325 2.18.2 Looking up or entering a string
7326 --------------------------------------
7328 The function `bfd_hash_lookup' is used both to look up a string in the
7329 hash table and to create a new entry.
7331 If the CREATE argument is `FALSE', `bfd_hash_lookup' will look up a
7332 string. If the string is found, it will returns a pointer to a `struct
7333 bfd_hash_entry'. If the string is not found in the table
7334 `bfd_hash_lookup' will return `NULL'. You should not modify any of the
7335 fields in the returns `struct bfd_hash_entry'.
7337 If the CREATE argument is `TRUE', the string will be entered into
7338 the hash table if it is not already there. Either way a pointer to a
7339 `struct bfd_hash_entry' will be returned, either to the existing
7340 structure or to a newly created one. In this case, a `NULL' return
7341 means that an error occurred.
7343 If the CREATE argument is `TRUE', and a new entry is created, the
7344 COPY argument is used to decide whether to copy the string onto the
7345 hash table objalloc or not. If COPY is passed as `FALSE', you must be
7346 careful not to deallocate or modify the string as long as the hash table

7352 2.18.3 Traversing a hash table
7353 ------------------------------
7355 The function `bfd_hash_traverse' may be used to traverse a hash table,
7356 calling a function on each element. The traversal is done in a random
7359 `bfd_hash_traverse' takes as arguments a function and a generic
7360 `void *' pointer. The function is called with a hash table entry (a
7361 `struct bfd_hash_entry *') and the generic pointer passed to
7362 `bfd_hash_traverse'. The function must return a `boolean' value, which
7363 indicates whether to continue traversing the hash table. If the
7364 function returns `FALSE', `bfd_hash_traverse' will stop the traversal
7365 and return immediately.

7370 2.18.4 Deriving a new hash table type
7371 -------------------------------------
7373 Many uses of hash tables want to store additional information which
7374 each entry in the hash table. Some also find it convenient to store
7375 additional information with the hash table itself. This may be done
7376 using a derived hash table.
7378 Since C is not an object oriented language, creating a derived hash
7379 table requires sticking together some boilerplate routines with a few
7380 differences specific to the type of hash table you want to create.
7382 An example of a derived hash table is the linker hash table. The
7383 structures for this are defined in `bfdlink.h'. The functions are in
7386 You may also derive a hash table from an already derived hash table.
7387 For example, the a.out linker backend code uses a hash table derived
7388 from the linker hash table.

7399 2.18.4.1 Define the derived structures
7400 ......................................
7402 You must define a structure for an entry in the hash table, and a
7403 structure for the hash table itself.
7405 The first field in the structure for an entry in the hash table must
7406 be of the type used for an entry in the hash table you are deriving
7407 from. If you are deriving from a basic hash table this is `struct
7408 bfd_hash_entry', which is defined in `bfd.h'. The first field in the
7409 structure for the hash table itself must be of the type of the hash
7410 table you are deriving from itself. If you are deriving from a basic
7411 hash table, this is `struct bfd_hash_table'.
7413 For example, the linker hash table defines `struct
7414 bfd_link_hash_entry' (in `bfdlink.h'). The first field, `root', is of
7415 type `struct bfd_hash_entry'. Similarly, the first field in `struct
7416 bfd_link_hash_table', `table', is of type `struct bfd_hash_table'.
7419 File: bfd.info, Node: Write the Derived Creation Routine, Next: Write Other Derived Routines, Prev: Define the Derived Structures, Up: Deriving a New Hash Table Type
7421 2.18.4.2 Write the derived creation routine
7422 ...........................................
7424 You must write a routine which will create and initialize an entry in
7425 the hash table. This routine is passed as the function argument to
7426 `bfd_hash_table_init'.
7428 In order to permit other hash tables to be derived from the hash
7429 table you are creating, this routine must be written in a standard way.
7431 The first argument to the creation routine is a pointer to a hash
7432 table entry. This may be `NULL', in which case the routine should
7433 allocate the right amount of space. Otherwise the space has already
7434 been allocated by a hash table type derived from this one.
7436 After allocating space, the creation routine must call the creation
7437 routine of the hash table type it is derived from, passing in a pointer
7438 to the space it just allocated. This will initialize any fields used
7439 by the base hash table.
7441 Finally the creation routine must initialize any local fields for
7442 the new hash table type.
7444 Here is a boilerplate example of a creation routine. FUNCTION_NAME
7445 is the name of the routine. ENTRY_TYPE is the type of an entry in the
7446 hash table you are creating. BASE_NEWFUNC is the name of the creation
7447 routine of the hash table type your hash table is derived from.
7449 struct bfd_hash_entry *
7450 FUNCTION_NAME (struct bfd_hash_entry *entry,
7451 struct bfd_hash_table *table,
7454 struct ENTRY_TYPE *ret = (ENTRY_TYPE *) entry;
7456 /* Allocate the structure if it has not already been allocated by a
7460 ret = bfd_hash_allocate (table, sizeof (* ret));
7465 /* Call the allocation method of the base class. */
7466 ret = ((ENTRY_TYPE *)
7467 BASE_NEWFUNC ((struct bfd_hash_entry *) ret, table, string));
7469 /* Initialize the local fields here. */
7471 return (struct bfd_hash_entry *) ret;
7474 The creation routine for the linker hash table, which is in `linker.c',
7475 looks just like this example. FUNCTION_NAME is
7476 `_bfd_link_hash_newfunc'. ENTRY_TYPE is `struct bfd_link_hash_entry'.
7477 BASE_NEWFUNC is `bfd_hash_newfunc', the creation routine for a basic
7480 `_bfd_link_hash_newfunc' also initializes the local fields in a
7481 linker hash table entry: `type', `written' and `next'.

7486 2.18.4.3 Write other derived routines
7487 .....................................
7489 You will want to write other routines for your new hash table, as well.
7491 You will want an initialization routine which calls the
7492 initialization routine of the hash table you are deriving from and
7493 initializes any other local fields. For the linker hash table, this is
7494 `_bfd_link_hash_table_init' in `linker.c'.
7496 You will want a lookup routine which calls the lookup routine of the
7497 hash table you are deriving from and casts the result. The linker hash
7498 table uses `bfd_link_hash_lookup' in `linker.c' (this actually takes an
7499 additional argument which it uses to decide how to return the looked up
7502 You may want a traversal routine. This should just call the
7503 traversal routine of the hash table you are deriving from with
7504 appropriate casts. The linker hash table uses `bfd_link_hash_traverse'
7507 These routines may simply be defined as macros. For example, the
7508 a.out backend linker hash table, which is derived from the linker hash
7509 table, uses macros for the lookup and traversal routines. These are
7510 `aout_link_hash_lookup' and `aout_link_hash_traverse' in aoutx.h.

7529 3.1 What to Put Where
7530 =====================
7532 All of BFD lives in one directory.
7535 File: bfd.info, Node: aout, Next: coff, Prev: What to Put Where, Up: BFD back ends
7541 BFD supports a number of different flavours of a.out format, though the
7542 major differences are only the sizes of the structures on disk, and the
7543 shape of the relocation information.
7545 The support is split into a basic support file `aoutx.h' and other
7546 files which derive functions from the base. One derivation file is
7547 `aoutf1.h' (for a.out flavour 1), and adds to the basic a.out functions
7548 support for sun3, sun4, 386 and 29k a.out files, to create a target
7549 jump vector for a specific target.
7551 This information is further split out into more specific files for
7552 each machine, including `sunos.c' for sun3 and sun4, `newsos3.c' for
7553 the Sony NEWS, and `demo64.c' for a demonstration of a 64 bit a.out
7556 The base file `aoutx.h' defines general mechanisms for reading and
7557 writing records to and from disk and various other methods which BFD
7558 requires. It is included by `aout32.c' and `aout64.c' to form the names
7559 `aout_32_swap_exec_header_in', `aout_64_swap_exec_header_in', etc.
7561 As an example, this is what goes on to make the back end for a sun4,
7564 #define ARCH_SIZE 32
7567 Which exports names:
7570 aout_32_canonicalize_reloc
7571 aout_32_find_nearest_line
7573 aout_32_get_reloc_upper_bound
7578 #define TARGET_NAME "a.out-sunos-big"
7579 #define VECNAME sunos_big_vec
7582 requires all the names from `aout32.c', and produces the jump vector
7586 The file `host-aout.c' is a special case. It is for a large set of
7587 hosts that use "more or less standard" a.out files, and for which
7588 cross-debugging is not interesting. It uses the standard 32-bit a.out
7589 support routines, but determines the file offsets and addresses of the
7590 text, data, and BSS sections, the machine architecture and machine
7591 type, and the entry point address, in a host-dependent manner. Once
7592 these values have been determined, generic code is used to handle the
7595 When porting it to run on a new system, you must supply:
7599 HOST_MACHINE_ARCH (optional)
7600 HOST_MACHINE_MACHINE (optional)
7601 HOST_TEXT_START_ADDR
7604 in the file `../include/sys/h-XXX.h' (for your host). These values,
7605 plus the structures and macros defined in `a.out.h' on your host
7606 system, will produce a BFD target that will access ordinary a.out files
7607 on your host. To configure a new machine to use `host-aout.c', specify:
7609 TDEFAULTS = -DDEFAULT_VECTOR=host_aout_big_vec
7610 TDEPFILES= host-aout.o trad-core.o
7612 in the `config/XXX.mt' file, and modify `configure.in' to use the
7613 `XXX.mt' file (by setting "`bfd_target=XXX'") when your configuration
7620 The file `aoutx.h' provides for both the _standard_ and _extended_
7621 forms of a.out relocation records.
7623 The standard records contain only an address, a symbol index, and a
7624 type field. The extended records (used on 29ks and sparcs) also have a
7625 full integer for an addend.
7627 3.2.2 Internal entry points
7628 ---------------------------
7631 `aoutx.h' exports several routines for accessing the contents of an
7632 a.out file, which are gathered and exported in turn by various format
7633 specific files (eg sunos.c).
7635 3.2.2.1 `aout_SIZE_swap_exec_header_in'

7645 byte stream memory image into the internal exec header structure EXECP.

7648 ........................................
7651 void aout_SIZE_swap_exec_header_out
7653 struct internal_exec *execp,
7654 struct external_exec *raw_bytes);
7656 Swap the information in an internal exec header structure EXECP into
7657 the buffer RAW_BYTES ready for writing to disk.

7665 struct internal_exec *execp,
7666 const bfd_target *(*callback_to_real_object_p) (bfd *));
7668 Some a.out variant thinks that the file open in ABFD checking is an
7669 a.out file. Do some more checking, and set up for access if it really
7670 is. Call back to the calling environment's "finish up" function just
7671 before returning, to handle any last-minute setup.

7727 BFD supports a number of different flavours of coff format. The major
7728 differences between formats are the sizes and alignments of fields in
7729 structures on disk, and the occasional extra field.
7731 Coff in all its varieties is implemented with a few common files and
7732 a number of implementation specific files. For example, The 88k bcs
7733 coff format is implemented in the file `coff-m88k.c'. This file
7734 `#include's `coff/m88k.h' which defines the external structure of the
7735 coff format for the 88k, and `coff/internal.h' which defines the
7736 internal structure. `coff-m88k.c' also defines the relocations used by
7737 the 88k format *Note Relocations::.
7739 The Intel i960 processor version of coff is implemented in
7740 `coff-i960.c'. This file has the same structure as `coff-m88k.c',
7741 except that it includes `coff/i960.h' rather than `coff-m88k.h'.
7743 3.3.1 Porting to a new version of coff
7744 --------------------------------------
7746 The recommended method is to select from the existing implementations
7747 the version of coff which is most like the one you want to use. For
7748 example, we'll say that i386 coff is the one you select, and that your
7749 coff flavour is called foo. Copy `i386coff.c' to `foocoff.c', copy
7750 `../include/coff/i386.h' to `../include/coff/foo.h', and add the lines
7751 to `targets.c' and `Makefile.in' so that your new back end is used.
7752 Alter the shapes of the structures in `../include/coff/foo.h' so that
7753 they match what you need. You will probably also have to add `#ifdef's
7754 to the code in `coff/internal.h' and `coffcode.h' if your version of
7757 You can verify that your new BFD backend works quite simply by
7758 building `objdump' from the `binutils' directory, and making sure that
7759 its version of what's going on and your host system's idea (assuming it
7760 has the pretty standard coff dump utility, usually called `att-dump' or
7761 just `dump') are the same. Then clean up your code, and send what
7762 you've done to Cygnus. Then your stuff will be in the next release, and
7763 you won't have to keep integrating it.
7765 3.3.2 How the coff backend works
7766 --------------------------------
7771 The Coff backend is split into generic routines that are applicable to
7772 any Coff target and routines that are specific to a particular target.
7773 The target-specific routines are further split into ones which are
7774 basically the same for all Coff targets except that they use the
7775 external symbol format or use different values for certain constants.
7777 The generic routines are in `coffgen.c'. These routines work for
7778 any Coff target. They use some hooks into the target specific code;
7779 the hooks are in a `bfd_coff_backend_data' structure, one of which
7780 exists for each target.
7782 The essentially similar target-specific routines are in
7783 `coffcode.h'. This header file includes executable C code. The
7784 various Coff targets first include the appropriate Coff header file,
7785 make any special defines that are needed, and then include `coffcode.h'.
7787 Some of the Coff targets then also have additional routines in the
7788 target source file itself.
7790 For example, `coff-i960.c' includes `coff/internal.h' and
7791 `coff/i960.h'. It then defines a few constants, such as `I960', and
7792 includes `coffcode.h'. Since the i960 has complex relocation types,
7793 `coff-i960.c' also includes some code to manipulate the i960 relocs.
7794 This code is not in `coffcode.h' because it would not be used by any
7797 3.3.2.2 Bit twiddling
7798 .....................
7800 Each flavour of coff supported in BFD has its own header file
7801 describing the external layout of the structures. There is also an
7802 internal description of the coff layout, in `coff/internal.h'. A major
7803 function of the coff backend is swapping the bytes and twiddling the
7804 bits to translate the external form of the structures into the normal
7805 internal form. This is all performed in the `bfd_swap'_thing_direction
7806 routines. Some elements are different sizes between different versions
7807 of coff; it is the duty of the coff version specific include file to
7808 override the definitions of various packing routines in `coffcode.h'.
7809 E.g., the size of line number entry in coff is sometimes 16 bits, and
7810 sometimes 32 bits. `#define'ing `PUT_LNSZ_LNNO' and `GET_LNSZ_LNNO'
7811 will select the correct one. No doubt, some day someone will find a
7812 version of coff which has a varying field size not catered to at the
7813 moment. To port BFD, that person will have to add more `#defines'.
7814 Three of the bit twiddling routines are exported to `gdb';
7815 `coff_swap_aux_in', `coff_swap_sym_in' and `coff_swap_lineno_in'. `GDB'
7816 reads the symbol table on its own, but uses BFD to fix things up. More
7817 of the bit twiddlers are exported for `gas'; `coff_swap_aux_out',
7818 `coff_swap_sym_out', `coff_swap_lineno_out', `coff_swap_reloc_out',
7819 `coff_swap_filehdr_out', `coff_swap_aouthdr_out',
7820 `coff_swap_scnhdr_out'. `Gas' currently keeps track of all the symbol
7821 table and reloc drudgery itself, thereby saving the internal BFD
7822 overhead, but uses BFD to swap things on the way out, making cross
7823 ports much safer. Doing so also allows BFD (and thus the linker) to
7824 use the same header files as `gas', which makes one avenue to disaster
7827 3.3.2.3 Symbol reading
7828 ......................
7830 The simple canonical form for symbols used by BFD is not rich enough to
7831 keep all the information available in a coff symbol table. The back end
7832 gets around this problem by keeping the original symbol table around,
7833 "behind the scenes".
7835 When a symbol table is requested (through a call to
7836 `bfd_canonicalize_symtab'), a request gets through to
7837 `coff_get_normalized_symtab'. This reads the symbol table from the coff
7838 file and swaps all the structures inside into the internal form. It
7839 also fixes up all the pointers in the table (represented in the file by
7840 offsets from the first symbol in the table) into physical pointers to
7841 elements in the new internal table. This involves some work since the
7842 meanings of fields change depending upon context: a field that is a
7843 pointer to another structure in the symbol table at one moment may be
7844 the size in bytes of a structure at the next. Another pass is made
7845 over the table. All symbols which mark file names (`C_FILE' symbols)
7846 are modified so that the internal string points to the value in the
7847 auxent (the real filename) rather than the normal text associated with
7848 the symbol (`".file"').
7850 At this time the symbol names are moved around. Coff stores all
7851 symbols less than nine characters long physically within the symbol
7852 table; longer strings are kept at the end of the file in the string
7853 table. This pass moves all strings into memory and replaces them with
7854 pointers to the strings.
7856 The symbol table is massaged once again, this time to create the
7857 canonical table used by the BFD application. Each symbol is inspected
7858 in turn, and a decision made (using the `sclass' field) about the
7859 various flags to set in the `asymbol'. *Note Symbols::. The generated
7860 canonical table shares strings with the hidden internal symbol table.
7862 Any linenumbers are read from the coff file too, and attached to the
7863 symbols which own the functions the linenumbers belong to.
7865 3.3.2.4 Symbol writing
7866 ......................
7868 Writing a symbol to a coff file which didn't come from a coff file will
7869 lose any debugging information. The `asymbol' structure remembers the
7870 BFD from which the symbol was taken, and on output the back end makes
7871 sure that the same destination target as source target is present.
7873 When the symbols have come from a coff file then all the debugging
7874 information is preserved.
7876 Symbol tables are provided for writing to the back end in a vector
7877 of pointers to pointers. This allows applications like the linker to
7878 accumulate and output large symbol tables without having to do too much
7881 This function runs through the provided symbol table and patches
7882 each symbol marked as a file place holder (`C_FILE') to point to the
7883 next file place holder in the list. It also marks each `offset' field
7884 in the list with the offset from the first symbol of the current symbol.
7886 Another function of this procedure is to turn the canonical value
7887 form of BFD into the form used by coff. Internally, BFD expects symbol
7888 values to be offsets from a section base; so a symbol physically at
7889 0x120, but in a section starting at 0x100, would have the value 0x20.
7890 Coff expects symbols to contain their final value, so symbols have
7891 their values changed at this point to reflect their sum with their
7892 owning section. This transformation uses the `output_section' field of
7893 the `asymbol''s `asection' *Note Sections::.
7895 * `coff_mangle_symbols'
7896 This routine runs though the provided symbol table and uses the
7897 offsets generated by the previous pass and the pointers generated when
7898 the symbol table was read in to create the structured hierarchy
7899 required by coff. It changes each pointer to a symbol into the index
7900 into the symbol table of the asymbol.
7902 * `coff_write_symbols'
7903 This routine runs through the symbol table and patches up the
7904 symbols from their internal form into the coff way, calls the bit
7905 twiddlers, and writes out the table to the file.
7907 3.3.2.5 `coff_symbol_type'

8247 3.3.2.7 Writing relocations
8248 ...........................
8250 To write relocations, the back end steps though the canonical
8251 relocation table and create an `internal_reloc'. The symbol index to
8252 use is removed from the `offset' field in the symbol table supplied.
8253 The address comes directly from the sum of the section base address and
8254 the relocation offset; the type is dug directly from the howto field.
8255 Then the `internal_reloc' is swapped into the shape of an
8256 `external_reloc' and written out to disk.
8258 3.3.2.8 Reading linenumbers
8259 ...........................
8261 Creating the linenumber table is done by reading in the entire coff
8262 linenumber table, and creating another table for internal use.
8264 A coff linenumber table is structured so that each function is
8265 marked as having a line number of 0. Each line within the function is
8266 an offset from the first line in the function. The base of the line
8267 number information for the table is stored in the symbol associated
8270 Note: The PE format uses line number 0 for a flag indicating a new
8273 The information is copied from the external to the internal table,
8274 and each symbol which marks a function is marked by pointing its...
8276 How does this work ?
8278 3.3.2.9 Reading relocations
8279 ...........................
8281 Coff relocations are easily transformed into the internal BFD form
8284 Reading a coff relocation table is done in the following stages:
8286 * Read the entire coff relocation table into memory.
8288 * Process each relocation in turn; first swap it from the external
8289 to the internal form.
8291 * Turn the symbol referenced in the relocation's symbol index into a
8292 pointer into the canonical symbol table. This table is the same
8293 as the one returned by a call to `bfd_canonicalize_symtab'. The
8294 back end will call that routine and save the result if a
8295 canonicalization hasn't been done.
8297 * The reloc index is turned into a pointer to a howto structure, in
8298 a back end specific way. For instance, the 386 and 960 use the
8299 `r_type' to directly produce an index into a howto table vector;
8300 the 88k subtracts a number from the `r_type' field and creates an
8304 File: bfd.info, Node: elf, Next: mmo, Prev: coff, Up: BFD back ends
8309 BFD support for ELF formats is being worked on. Currently, the best
8310 supported back ends are for sparc and i386 (running svr4 or Solaris 2).
8312 Documentation of the internals of the support code still needs to be
8313 written. The code is changing quickly enough that we haven't bothered

8322 Helper functions for GDB to locate the string tables. Since BFD hides
8323 string tables from callers, GDB needs to use an internal hook to find
8324 them. Sun's .stabstr, in particular, isn't even pointed to by the
8325 .stab section, so ordinary mechanisms wouldn't work to find it, even if

8334 The mmo object format is used exclusively together with Professor
8335 Donald E. Knuth's educational 64-bit processor MMIX. The simulator
8336 `mmix' which is available at
8337 `http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz'
8338 understands this format. That package also includes a combined
8339 assembler and linker called `mmixal'. The mmo format has no advantages
8340 feature-wise compared to e.g. ELF. It is a simple non-relocatable
8341 object format with no support for archives or debugging information,
8342 except for symbol value information and line numbers (which is not yet
8343 implemented in BFD). See
8344 `http://www-cs-faculty.stanford.edu/~knuth/mmix.html' for more
8345 information about MMIX. The ELF format is used for intermediate object
8346 files in the BFD implementation.

8355 File: bfd.info, Node: File layout, Next: Symbol-table, Prev: mmo, Up: mmo
8360 The mmo file contents is not partitioned into named sections as with
8361 e.g. ELF. Memory areas is formed by specifying the location of the
8362 data that follows. Only the memory area `0x0000...00' to `0x01ff...ff'
8363 is executable, so it is used for code (and constants) and the area
8364 `0x2000...00' to `0x20ff...ff' is used for writable data. *Note mmo
8367 There is provision for specifying "special data" of 65536 different
8368 types. We use type 80 (decimal), arbitrarily chosen the same as the
8369 ELF `e_machine' number for MMIX, filling it with section information
8370 normally found in ELF objects. *Note mmo section mapping::.
8372 Contents is entered as 32-bit words, xor:ed over previous contents,
8373 always zero-initialized. A word that starts with the byte `0x98' forms
8374 a command called a `lopcode', where the next byte distinguished between
8375 the thirteen lopcodes. The two remaining bytes, called the `Y' and `Z'
8376 fields, or the `YZ' field (a 16-bit big-endian number), are used for
8377 various purposes different for each lopcode. As documented in
8378 `http://www-cs-faculty.stanford.edu/~knuth/mmixal-intro.ps.gz', the
8382 0x98000001. The next word is contents, regardless of whether it
8383 starts with 0x98 or not.
8386 0x9801YYZZ, where `Z' is 1 or 2. This is a location directive,
8387 setting the location for the next data to the next 32-bit word
8388 (for Z = 1) or 64-bit word (for Z = 2), plus Y * 2^56. Normally
8389 `Y' is 0 for the text segment and 2 for the data segment.
8392 0x9802YYZZ. Increase the current location by `YZ' bytes.
8395 0x9803YYZZ, where `Z' is 1 or 2. Store the current location as 64
8396 bits into the location pointed to by the next 32-bit (Z = 1) or
8397 64-bit (Z = 2) word, plus Y * 2^56.
8400 0x9804YYZZ. `YZ' is stored into the current location plus 2 - 4 *
8404 0x980500ZZ. `Z' is 16 or 24. A value `L' derived from the
8405 following 32-bit word are used in a manner similar to `YZ' in
8406 lop_fixr: it is xor:ed into the current location minus 4 * L. The
8407 first byte of the word is 0 or 1. If it is 1, then L = (LOWEST 24
8408 BITS OF WORD) - 2^Z, if 0, then L = (LOWEST 24 BITS OF WORD).
8411 0x9806YYZZ. `Y' is the file number, `Z' is count of 32-bit words.
8412 Set the file number to `Y' and the line counter to 0. The next Z
8413 * 4 bytes contain the file name, padded with zeros if the count is
8414 not a multiple of four. The same `Y' may occur multiple times,
8415 but `Z' must be 0 for all but the first occurrence.
8418 0x9807YYZZ. `YZ' is the line number. Together with lop_file, it
8419 forms the source location for the next 32-bit word. Note that for
8420 each non-lopcode 32-bit word, line numbers are assumed incremented
8424 0x9808YYZZ. `YZ' is the type number. Data until the next lopcode
8425 other than lop_quote forms special data of type `YZ'. *Note mmo
8428 Other types than 80, (or type 80 with a content that does not
8429 parse) is stored in sections named `.MMIX.spec_data.N' where N is
8430 the `YZ'-type. The flags for such a sections say not to allocate
8431 or load the data. The vma is 0. Contents of multiple occurrences
8432 of special data N is concatenated to the data of the previous
8433 lop_spec Ns. The location in data or code at which the lop_spec
8437 0x980901ZZ. The first lopcode in a file. The `Z' field forms the
8438 length of header information in 32-bit words, where the first word
8439 tells the time in seconds since `00:00:00 GMT Jan 1 1970'.
8442 0x980a00ZZ. Z > 32. This lopcode follows after all
8443 content-generating lopcodes in a program. The `Z' field denotes
8444 the value of `rG' at the beginning of the program. The following
8445 256 - Z big-endian 64-bit words are loaded into global registers
8449 0x980b0000. The next-to-last lopcode in a program. Must follow
8450 immediately after the lop_post lopcode and its data. After this
8451 lopcode follows all symbols in a compressed format (*note
8455 0x980cYYZZ. The last lopcode in a program. It must follow the
8456 lop_stab lopcode and its data. The `YZ' field contains the number
8457 of 32-bit words of symbol table information after the preceding
8460 Note that the lopcode "fixups"; `lop_fixr', `lop_fixrx' and
8461 `lop_fixo' are not generated by BFD, but are handled. They are
8462 generated by `mmixal'.
8464 This trivial one-label, one-instruction file:
8468 can be represented this way in mmo:
8470 0x98090101 - lop_pre, one 32-bit word with timestamp.
8472 0x98010002 - lop_loc, text segment, using a 64-bit address.
8473 Note that mmixal does not emit this for the file above.
8474 0x00000000 - Address, high 32 bits.
8475 0x00000000 - Address, low 32 bits.
8476 0x98060002 - lop_file, 2 32-bit words for file-name.
8478 0x2e730000 - ".s\0\0"
8479 0x98070001 - lop_line, line 1.
8480 0x00010203 - TRAP 1,2,3
8481 0x980a00ff - lop_post, setting $255 to 0.
8484 0x980b0000 - lop_stab for ":Main" = 0, serial 1.
8485 0x203a4040 *Note Symbol-table::.
8490 0x980c0005 - lop_end; symbol table contained five 32-bit words.

8495 3.5.2 Symbol table format
8496 -------------------------
8498 From mmixal.w (or really, the generated mmixal.tex) in
8499 `http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz'):
8500 "Symbols are stored and retrieved by means of a `ternary search trie',
8501 following ideas of Bentley and Sedgewick. (See ACM-SIAM Symp. on
8502 Discrete Algorithms `8' (1997), 360-369; R.Sedgewick, `Algorithms in C'
8503 (Reading, Mass. Addison-Wesley, 1998), `15.4'.) Each trie node stores
8504 a character, and there are branches to subtries for the cases where a
8505 given character is less than, equal to, or greater than the character
8506 in the trie. There also is a pointer to a symbol table entry if a
8507 symbol ends at the current node."
8509 So it's a tree encoded as a stream of bytes. The stream of bytes
8510 acts on a single virtual global symbol, adding and removing characters
8511 and signalling complete symbol points. Here, we read the stream and
8512 create symbols at the completion points.
8514 First, there's a control byte `m'. If any of the listed bits in `m'
8515 is nonzero, we execute what stands at the right, in the listed order:
8518 0x40 - Traverse left trie.
8519 (Read a new command byte and recurse.)
8522 0x2f - Read the next byte as a character and store it in the
8523 current character position; increment character position.
8524 Test the bits of `m':
8527 0x80 - The character is 16-bit (so read another byte,
8528 merge into current character.
8531 0xf - We have a complete symbol; parse the type, value
8532 and serial number and do what should be done
8533 with a symbol. The type and length information
8534 is in j = (m & 0xf).
8537 j == 0xf: A register variable. The following
8538 byte tells which register.
8539 j <= 8: An absolute symbol. Read j bytes as the
8540 big-endian number the symbol equals.
8541 A j = 2 with two zero bytes denotes an
8543 j > 8: As with j <= 8, but add (0x20 << 56)
8544 to the value in the following j - 8
8547 Then comes the serial number, as a variant of
8548 uleb128, but better named ubeb128:
8549 Read bytes and shift the previous value left 7
8550 (multiply by 128). Add in the new byte, repeat
8551 until a byte has bit 7 set. The serial number
8552 is the computed value minus 128.
8555 0x20 - Traverse middle trie. (Read a new command byte
8556 and recurse.) Decrement character position.
8559 0x10 - Traverse right trie. (Read a new command byte and
8562 Let's look again at the `lop_stab' for the trivial file (*note File
8565 0x980b0000 - lop_stab for ":Main" = 0, serial 1.
8572 This forms the trivial trie (note that the path between ":" and "M"
8584 016e "n" is the last character in a full symbol, and
8585 with a value represented in one byte.
8587 81 The serial number is 1.

8592 3.5.3 mmo section mapping
8593 -------------------------
8595 The implementation in BFD uses special data type 80 (decimal) to
8596 encapsulate and describe named sections, containing e.g. debug
8597 information. If needed, any datum in the encapsulation will be quoted
8598 using lop_quote. First comes a 32-bit word holding the number of
8599 32-bit words containing the zero-terminated zero-padded segment name.
8600 After the name there's a 32-bit word holding flags describing the
8601 section type. Then comes a 64-bit big-endian word with the section
8602 length (in bytes), then another with the section start address.
8603 Depending on the type of section, the contents might follow,
8604 zero-padded to 32-bit boundary. For a loadable section (such as data
8605 or code), the contents might follow at some later point, not
8606 necessarily immediately, as a lop_loc with the same start address as in
8607 the section description, followed by the contents. This in effect
8608 forms a descriptor that must be emitted before the actual contents.
8609 Sections described this way must not overlap.
8611 For areas that don't have such descriptors, synthetic sections are
8612 formed by BFD. Consecutive contents in the two memory areas
8613 `0x0000...00' to `0x01ff...ff' and `0x2000...00' to `0x20ff...ff' are
8614 entered in sections named `.text' and `.data' respectively. If an area
8615 is not otherwise described, but would together with a neighboring lower
8616 area be less than `0x40000000' bytes long, it is joined with the lower
8617 area and the gap is zero-filled. For other cases, a new section is
8618 formed, named `.MMIX.sec.N'. Here, N is a number, a running count
8619 through the mmo file, starting at 0.
8621 A loadable section specified as:
8623 .section secname,"ax"
8624 TETRA 1,2,3,4,-1,-2009
8627 and linked to address `0x4', is represented by the sequence:
8629 0x98080050 - lop_spec 80
8630 0x00000002 - two 32-bit words for the section name
8632 0x616d6500 - "ame\0"
8633 0x00000033 - flags CODE, READONLY, LOAD, ALLOC
8634 0x00000000 - high 32 bits of section length
8635 0x0000001c - section length is 28 bytes; 6 * 4 + 1 + alignment to 32 bits
8636 0x00000000 - high 32 bits of section address
8637 0x00000004 - section address is 4
8638 0x98010002 - 64 bits with address of following data
8639 0x00000000 - high 32 bits of address
8640 0x00000004 - low 32 bits: data starts at address 4
8647 0x50000000 - 80 as a byte, padded with zeros.
8649 Note that the lop_spec wrapping does not include the section
8650 contents. Compare this to a non-loaded section specified as:
8656 This, when linked to address `0x200000000000001c', is represented by:
8658 0x98080050 - lop_spec 80
8659 0x00000002 - two 32-bit words for the section name
8662 0x00000010 - flag READONLY
8663 0x00000000 - high 32 bits of section length
8664 0x0000000c - section length is 12 bytes; 2 * 4 + 2 + alignment to 32 bits
8665 0x20000000 - high 32 bits of address
8666 0x0000001c - low 32 bits of address 0x200000000000001c
8669 0x26280000 - 38, 40 as bytes, padded with zeros
8671 For the latter example, the section contents must not be loaded in
8672 memory, and is therefore specified as part of the special data. The
8673 address is usually unimportant but might provide information for e.g.
8674 the DWARF 2 debugging format.

8687 Everyone is permitted to copy and distribute verbatim copies
8688 of this license document, but changing it is not allowed.
8693 The purpose of this License is to make a manual, textbook, or other
8694 written document "free" in the sense of freedom: to assure everyone
8695 the effective freedom to copy and redistribute it, with or without
8696 modifying it, either commercially or noncommercially. Secondarily,
8697 this License preserves for the author and publisher a way to get
8698 credit for their work, while not being considered responsible for
8699 modifications made by others.
8701 This License is a kind of "copyleft", which means that derivative
8702 works of the document must themselves be free in the same sense.
8703 It complements the GNU General Public License, which is a copyleft
8704 license designed for free software.
8706 We have designed this License in order to use it for manuals for
8707 free software, because free software needs free documentation: a
8708 free program should come with manuals providing the same freedoms
8709 that the software does. But this License is not limited to
8710 software manuals; it can be used for any textual work, regardless
8711 of subject matter or whether it is published as a printed book.
8712 We recommend this License principally for works whose purpose is
8713 instruction or reference.
8716 1. APPLICABILITY AND DEFINITIONS
8718 This License applies to any manual or other work that contains a
8719 notice placed by the copyright holder saying it can be distributed
8720 under the terms of this License. The "Document", below, refers to
8721 any such manual or work. Any member of the public is a licensee,
8722 and is addressed as "you."
8724 A "Modified Version" of the Document means any work containing the
8725 Document or a portion of it, either copied verbatim, or with
8726 modifications and/or translated into another language.
8728 A "Secondary Section" is a named appendix or a front-matter
8729 section of the Document that deals exclusively with the
8730 relationship of the publishers or authors of the Document to the
8731 Document's overall subject (or to related matters) and contains
8732 nothing that could fall directly within that overall subject.
8733 (For example, if the Document is in part a textbook of
8734 mathematics, a Secondary Section may not explain any mathematics.)
8735 The relationship could be a matter of historical connection with
8736 the subject or with related matters, or of legal, commercial,
8737 philosophical, ethical or political position regarding them.
8739 The "Invariant Sections" are certain Secondary Sections whose
8740 titles are designated, as being those of Invariant Sections, in
8741 the notice that says that the Document is released under this
8744 The "Cover Texts" are certain short passages of text that are
8745 listed, as Front-Cover Texts or Back-Cover Texts, in the notice
8746 that says that the Document is released under this License.
8748 A "Transparent" copy of the Document means a machine-readable copy,
8749 represented in a format whose specification is available to the
8750 general public, whose contents can be viewed and edited directly
8751 and straightforwardly with generic text editors or (for images
8752 composed of pixels) generic paint programs or (for drawings) some
8753 widely available drawing editor, and that is suitable for input to
8754 text formatters or for automatic translation to a variety of
8755 formats suitable for input to text formatters. A copy made in an
8756 otherwise Transparent file format whose markup has been designed
8757 to thwart or discourage subsequent modification by readers is not
8758 Transparent. A copy that is not "Transparent" is called "Opaque."
8760 Examples of suitable formats for Transparent copies include plain
8761 ASCII without markup, Texinfo input format, LaTeX input format,
8762 SGML or XML using a publicly available DTD, and
8763 standard-conforming simple HTML designed for human modification.
8764 Opaque formats include PostScript, PDF, proprietary formats that
8765 can be read and edited only by proprietary word processors, SGML
8766 or XML for which the DTD and/or processing tools are not generally
8767 available, and the machine-generated HTML produced by some word
8768 processors for output purposes only.
8770 The "Title Page" means, for a printed book, the title page itself,
8771 plus such following pages as are needed to hold, legibly, the
8772 material this License requires to appear in the title page. For
8773 works in formats which do not have any title page as such, "Title
8774 Page" means the text near the most prominent appearance of the
8775 work's title, preceding the beginning of the body of the text.
8779 You may copy and distribute the Document in any medium, either
8780 commercially or noncommercially, provided that this License, the
8781 copyright notices, and the license notice saying this License
8782 applies to the Document are reproduced in all copies, and that you
8783 add no other conditions whatsoever to those of this License. You
8784 may not use technical measures to obstruct or control the reading
8785 or further copying of the copies you make or distribute. However,
8786 you may accept compensation in exchange for copies. If you
8787 distribute a large enough number of copies you must also follow
8788 the conditions in section 3.
8790 You may also lend copies, under the same conditions stated above,
8791 and you may publicly display copies.
8793 3. COPYING IN QUANTITY
8795 If you publish printed copies of the Document numbering more than
8796 100, and the Document's license notice requires Cover Texts, you
8797 must enclose the copies in covers that carry, clearly and legibly,
8798 all these Cover Texts: Front-Cover Texts on the front cover, and
8799 Back-Cover Texts on the back cover. Both covers must also clearly
8800 and legibly identify you as the publisher of these copies. The
8801 front cover must present the full title with all words of the
8802 title equally prominent and visible. You may add other material
8803 on the covers in addition. Copying with changes limited to the
8804 covers, as long as they preserve the title of the Document and
8805 satisfy these conditions, can be treated as verbatim copying in
8808 If the required texts for either cover are too voluminous to fit
8809 legibly, you should put the first ones listed (as many as fit
8810 reasonably) on the actual cover, and continue the rest onto
8813 If you publish or distribute Opaque copies of the Document
8814 numbering more than 100, you must either include a
8815 machine-readable Transparent copy along with each Opaque copy, or
8816 state in or with each Opaque copy a publicly-accessible
8817 computer-network location containing a complete Transparent copy
8818 of the Document, free of added material, which the general
8819 network-using public has access to download anonymously at no
8820 charge using public-standard network protocols. If you use the
8821 latter option, you must take reasonably prudent steps, when you
8822 begin distribution of Opaque copies in quantity, to ensure that
8823 this Transparent copy will remain thus accessible at the stated
8824 location until at least one year after the last time you
8825 distribute an Opaque copy (directly or through your agents or
8826 retailers) of that edition to the public.
8828 It is requested, but not required, that you contact the authors of
8829 the Document well before redistributing any large number of
8830 copies, to give them a chance to provide you with an updated
8831 version of the Document.
8835 You may copy and distribute a Modified Version of the Document
8836 under the conditions of sections 2 and 3 above, provided that you
8837 release the Modified Version under precisely this License, with
8838 the Modified Version filling the role of the Document, thus
8839 licensing distribution and modification of the Modified Version to
8840 whoever possesses a copy of it. In addition, you must do these
8841 things in the Modified Version:
8843 A. Use in the Title Page (and on the covers, if any) a title
8844 distinct from that of the Document, and from those of previous
8845 versions (which should, if there were any, be listed in the
8846 History section of the Document). You may use the same title
8847 as a previous version if the original publisher of that version
8849 B. List on the Title Page, as authors, one or more persons or
8850 entities responsible for authorship of the modifications in the
8851 Modified Version, together with at least five of the principal
8852 authors of the Document (all of its principal authors, if it
8853 has less than five).
8854 C. State on the Title page the name of the publisher of the
8855 Modified Version, as the publisher.
8856 D. Preserve all the copyright notices of the Document.
8857 E. Add an appropriate copyright notice for your modifications
8858 adjacent to the other copyright notices.
8859 F. Include, immediately after the copyright notices, a license
8860 notice giving the public permission to use the Modified Version
8861 under the terms of this License, in the form shown in the
8863 G. Preserve in that license notice the full lists of Invariant
8864 Sections and required Cover Texts given in the Document's
8866 H. Include an unaltered copy of this License.
8867 I. Preserve the section entitled "History", and its title, and add
8868 to it an item stating at least the title, year, new authors, and
8869 publisher of the Modified Version as given on the Title Page.
8870 If there is no section entitled "History" in the Document,
8871 create one stating the title, year, authors, and publisher of
8872 the Document as given on its Title Page, then add an item
8873 describing the Modified Version as stated in the previous
8875 J. Preserve the network location, if any, given in the Document for
8876 public access to a Transparent copy of the Document, and
8877 likewise the network locations given in the Document for
8878 previous versions it was based on. These may be placed in the
8879 "History" section. You may omit a network location for a work
8880 that was published at least four years before the Document
8881 itself, or if the original publisher of the version it refers
8882 to gives permission.
8883 K. In any section entitled "Acknowledgements" or "Dedications",
8884 preserve the section's title, and preserve in the section all the
8885 substance and tone of each of the contributor acknowledgements
8886 and/or dedications given therein.
8887 L. Preserve all the Invariant Sections of the Document,
8888 unaltered in their text and in their titles. Section numbers
8889 or the equivalent are not considered part of the section titles.
8890 M. Delete any section entitled "Endorsements." Such a section
8891 may not be included in the Modified Version.
8892 N. Do not retitle any existing section as "Endorsements" or to
8893 conflict in title with any Invariant Section.
8895 If the Modified Version includes new front-matter sections or
8896 appendices that qualify as Secondary Sections and contain no
8897 material copied from the Document, you may at your option
8898 designate some or all of these sections as invariant. To do this,
8899 add their titles to the list of Invariant Sections in the Modified
8900 Version's license notice. These titles must be distinct from any
8901 other section titles.
8903 You may add a section entitled "Endorsements", provided it contains
8904 nothing but endorsements of your Modified Version by various
8905 parties-for example, statements of peer review or that the text has
8906 been approved by an organization as the authoritative definition
8909 You may add a passage of up to five words as a Front-Cover Text,
8910 and a passage of up to 25 words as a Back-Cover Text, to the end
8911 of the list of Cover Texts in the Modified Version. Only one
8912 passage of Front-Cover Text and one of Back-Cover Text may be
8913 added by (or through arrangements made by) any one entity. If the
8914 Document already includes a cover text for the same cover,
8915 previously added by you or by arrangement made by the same entity
8916 you are acting on behalf of, you may not add another; but you may
8917 replace the old one, on explicit permission from the previous
8918 publisher that added the old one.
8920 The author(s) and publisher(s) of the Document do not by this
8921 License give permission to use their names for publicity for or to
8922 assert or imply endorsement of any Modified Version.
8924 5. COMBINING DOCUMENTS
8926 You may combine the Document with other documents released under
8927 this License, under the terms defined in section 4 above for
8928 modified versions, provided that you include in the combination
8929 all of the Invariant Sections of all of the original documents,
8930 unmodified, and list them all as Invariant Sections of your
8931 combined work in its license notice.
8933 The combined work need only contain one copy of this License, and
8934 multiple identical Invariant Sections may be replaced with a single
8935 copy. If there are multiple Invariant Sections with the same name
8936 but different contents, make the title of each such section unique
8937 by adding at the end of it, in parentheses, the name of the
8938 original author or publisher of that section if known, or else a
8939 unique number. Make the same adjustment to the section titles in
8940 the list of Invariant Sections in the license notice of the
8943 In the combination, you must combine any sections entitled
8944 "History" in the various original documents, forming one section
8945 entitled "History"; likewise combine any sections entitled
8946 "Acknowledgements", and any sections entitled "Dedications." You
8947 must delete all sections entitled "Endorsements."
8949 6. COLLECTIONS OF DOCUMENTS
8951 You may make a collection consisting of the Document and other
8952 documents released under this License, and replace the individual
8953 copies of this License in the various documents with a single copy
8954 that is included in the collection, provided that you follow the
8955 rules of this License for verbatim copying of each of the
8956 documents in all other respects.
8958 You may extract a single document from such a collection, and
8959 distribute it individually under this License, provided you insert
8960 a copy of this License into the extracted document, and follow
8961 this License in all other respects regarding verbatim copying of
8964 7. AGGREGATION WITH INDEPENDENT WORKS
8966 A compilation of the Document or its derivatives with other
8967 separate and independent documents or works, in or on a volume of
8968 a storage or distribution medium, does not as a whole count as a
8969 Modified Version of the Document, provided no compilation
8970 copyright is claimed for the compilation. Such a compilation is
8971 called an "aggregate", and this License does not apply to the
8972 other self-contained works thus compiled with the Document, on
8973 account of their being thus compiled, if they are not themselves
8974 derivative works of the Document.
8976 If the Cover Text requirement of section 3 is applicable to these
8977 copies of the Document, then if the Document is less than one
8978 quarter of the entire aggregate, the Document's Cover Texts may be
8979 placed on covers that surround only the Document within the
8980 aggregate. Otherwise they must appear on covers around the whole
8985 Translation is considered a kind of modification, so you may
8986 distribute translations of the Document under the terms of section
8987 4. Replacing Invariant Sections with translations requires special
8988 permission from their copyright holders, but you may include
8989 translations of some or all Invariant Sections in addition to the
8990 original versions of these Invariant Sections. You may include a
8991 translation of this License provided that you also include the
8992 original English version of this License. In case of a
8993 disagreement between the translation and the original English
8994 version of this License, the original English version will prevail.
8998 You may not copy, modify, sublicense, or distribute the Document
8999 except as expressly provided for under this License. Any other
9000 attempt to copy, modify, sublicense or distribute the Document is
9001 void, and will automatically terminate your rights under this
9002 License. However, parties who have received copies, or rights,
9003 from you under this License will not have their licenses
9004 terminated so long as such parties remain in full compliance.
9006 10. FUTURE REVISIONS OF THIS LICENSE
9008 The Free Software Foundation may publish new, revised versions of
9009 the GNU Free Documentation License from time to time. Such new
9010 versions will be similar in spirit to the present version, but may
9011 differ in detail to address new problems or concerns. See
9012 http://www.gnu.org/copyleft/.
9014 Each version of the License is given a distinguishing version
9015 number. If the Document specifies that a particular numbered
9016 version of this License "or any later version" applies to it, you
9017 have the option of following the terms and conditions either of
9018 that specified version or of any later version that has been
9019 published (not as a draft) by the Free Software Foundation. If
9020 the Document does not specify a version number of this License,
9021 you may choose any version ever published (not as a draft) by the
9022 Free Software Foundation.
9025 ADDENDUM: How to use this License for your documents
9026 ====================================================
9028 To use this License in a document you have written, include a copy of
9029 the License in the document and put the following copyright and license
9030 notices just after the title page:
9032 Copyright (C) YEAR YOUR NAME.
9033 Permission is granted to copy, distribute and/or modify this document
9034 under the terms of the GNU Free Documentation License, Version 1.1
9035 or any later version published by the Free Software Foundation;
9036 with the Invariant Sections being LIST THEIR TITLES, with the
9037 Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
9038 A copy of the license is included in the section entitled "GNU
9039 Free Documentation License."
9041 If you have no Invariant Sections, write "with no Invariant Sections"
9042 instead of saying which ones are invariant. If you have no Front-Cover
9043 Texts, write "no Front-Cover Texts" instead of "Front-Cover Texts being
9044 LIST"; likewise for Back-Cover Texts.
9046 If your document contains nontrivial examples of program code, we
9047 recommend releasing these examples in parallel under your choice of
9048 free software license, such as the GNU General Public License, to
9049 permit their use in free software.
