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

61 File: bfd.info, Node: History, Next: How It Works, Prev: Overview, Up: Overview
66 One spur behind BFD was the desire, on the part of the GNU 960 team at
67 Intel Oregon, for interoperability of applications on their COFF and
68 b.out file formats. Cygnus was providing GNU support for the team, and
69 was contracted to provide the required functionality.
71 The name came from a conversation David Wallace was having with
72 Richard Stallman about the library: RMS said that it would be quite
73 hard--David said "BFD". Stallman was right, but the name stuck.
75 At the same time, Ready Systems wanted much the same thing, but for
76 different object file formats: IEEE-695, Oasys, Srecords, a.out and 68k
79 BFD was first implemented by members of Cygnus Support; Steve
80 Chamberlain (`sac@cygnus.com'), John Gilmore (`gnu@cygnus.com'), K.
81 Richard Pixley (`rich@cygnus.com') and David Henkel-Wallace
85 File: bfd.info, Node: How It Works, Next: What BFD Version 2 Can Do, Prev: History, Up: Overview
90 To use the library, include `bfd.h' and link with `libbfd.a'.
92 BFD provides a common interface to the parts of an object file for a
95 When an application successfully opens a target file (object,
96 archive, or whatever), a pointer to an internal structure is returned.
97 This pointer points to a structure called `bfd', described in `bfd.h'.
98 Our convention is to call this pointer a BFD, and instances of it
99 within code `abfd'. All operations on the target object file are
100 applied as methods to the BFD. The mapping is defined within `bfd.h'
101 in a set of macros, all beginning with `bfd_' to reduce namespace
104 For example, this sequence does what you would probably expect:
105 return the number of sections in an object file attached to a BFD
110 unsigned int number_of_sections (abfd)
113 return bfd_count_sections (abfd);
116 The abstraction used within BFD is that an object file has:
120 * a number of sections containing raw data (*note Sections::),
122 * a set of relocations (*note Relocations::), and
124 * some symbol information (*note Symbols::).
125 Also, BFDs opened for archives have the additional attribute of an
126 index and contain subordinate BFDs. This approach is fine for a.out and
127 coff, but loses efficiency when applied to formats such as S-records and
131 File: bfd.info, Node: What BFD Version 2 Can Do, Prev: How It Works, Up: Overview
133 1.3 What BFD Version 2 Can Do
134 =============================
136 When an object file is opened, BFD subroutines automatically determine
137 the format of the input object file. They then build a descriptor in
138 memory with pointers to routines that will be used to access elements of
139 the object file's data structures.
141 As different information from the object files is required, BFD
142 reads from different sections of the file and processes them. For
143 example, a very common operation for the linker is processing symbol
144 tables. Each BFD back end provides a routine for converting between
145 the object file's representation of symbols and an internal canonical
146 format. When the linker asks for the symbol table of an object file, it
147 calls through a memory pointer to the routine from the relevant BFD
148 back end which reads and converts the table into a canonical form. The
149 linker then operates upon the canonical form. When the link is finished
150 and the linker writes the output file's symbol table, another BFD back
151 end routine is called to take the newly created symbol table and
152 convert it into the chosen output format.
156 * BFD information loss:: Information Loss
157 * Canonical format:: The BFD canonical object-file format
160 File: bfd.info, Node: BFD information loss, Next: Canonical format, Up: What BFD Version 2 Can Do
162 1.3.1 Information Loss
163 ----------------------
165 _Information can be lost during output._ The output formats supported
166 by BFD do not provide identical facilities, and information which can
167 be described in one form has nowhere to go in another format. One
168 example of this is alignment information in `b.out'. There is nowhere
169 in an `a.out' format file to store alignment information on the
170 contained data, so when a file is linked from `b.out' and an `a.out'
171 image is produced, alignment information will not propagate to the
172 output file. (The linker will still use the alignment information
173 internally, so the link is performed correctly).
175 Another example is COFF section names. COFF files may contain an
176 unlimited number of sections, each one with a textual section name. If
177 the target of the link is a format which does not have many sections
178 (e.g., `a.out') or has sections without names (e.g., the Oasys format),
179 the link cannot be done simply. You can circumvent this problem by
180 describing the desired input-to-output section mapping with the linker
183 _Information can be lost during canonicalization._ The BFD internal
184 canonical form of the external formats is not exhaustive; there are
185 structures in input formats for which there is no direct representation
186 internally. This means that the BFD back ends cannot maintain all
187 possible data richness through the transformation between external to
188 internal and back to external formats.
190 This limitation is only a problem when an application reads one
191 format and writes another. Each BFD back end is responsible for
192 maintaining as much data as possible, and the internal BFD canonical
193 form has structures which are opaque to the BFD core, and exported only
194 to the back ends. When a file is read in one format, the canonical form
195 is generated for BFD and the application. At the same time, the back
196 end saves away any information which may otherwise be lost. If the data
197 is then written back in the same format, the back end routine will be
198 able to use the canonical form provided by the BFD core as well as the
199 information it prepared earlier. Since there is a great deal of
200 commonality between back ends, there is no information lost when
201 linking or copying big endian COFF to little endian COFF, or `a.out' to
202 `b.out'. When a mixture of formats is linked, the information is only
203 lost from the files whose format differs from the destination.
206 File: bfd.info, Node: Canonical format, Prev: BFD information loss, Up: What BFD Version 2 Can Do
208 1.3.2 The BFD canonical object-file format
209 ------------------------------------------
211 The greatest potential for loss of information occurs when there is the
212 least overlap between the information provided by the source format,
213 that stored by the canonical format, and that needed by the destination
214 format. A brief description of the canonical form may help you
215 understand which kinds of data you can count on preserving across
219 Information stored on a per-file basis includes target machine
220 architecture, particular implementation format type, a demand
221 pageable bit, and a write protected bit. Information like Unix
222 magic numbers is not stored here--only the magic numbers' meaning,
223 so a `ZMAGIC' file would have both the demand pageable bit and the
224 write protected text bit set. The byte order of the target is
225 stored on a per-file basis, so that big- and little-endian object
226 files may be used with one another.
229 Each section in the input file contains the name of the section,
230 the section's original address in the object file, size and
231 alignment information, various flags, and pointers into other BFD
235 Each symbol contains a pointer to the information for the object
236 file which originally defined it, its name, its value, and various
237 flag bits. When a BFD back end reads in a symbol table, it
238 relocates all symbols to make them relative to the base of the
239 section where they were defined. Doing this ensures that each
240 symbol points to its containing section. Each symbol also has a
241 varying amount of hidden private data for the BFD back end. Since
242 the symbol points to the original file, the private data format
243 for that symbol is accessible. `ld' can operate on a collection
244 of symbols of wildly different formats without problems.
246 Normal global and simple local symbols are maintained on output,
247 so an output file (no matter its format) will retain symbols
248 pointing to functions and to global, static, and common variables.
249 Some symbol information is not worth retaining; in `a.out', type
250 information is stored in the symbol table as long symbol names.
251 This information would be useless to most COFF debuggers; the
252 linker has command line switches to allow users to throw it away.
254 There is one word of type information within the symbol, so if the
255 format supports symbol type information within symbols (for
256 example, COFF, IEEE, Oasys) and the type is simple enough to fit
257 within one word (nearly everything but aggregates), the
258 information will be preserved.
261 Each canonical BFD relocation record contains a pointer to the
262 symbol to relocate to, the offset of the data to relocate, the
263 section the data is in, and a pointer to a relocation type
264 descriptor. Relocation is performed by passing messages through
265 the relocation type descriptor and the symbol pointer. Therefore,
266 relocations can be performed on output data using a relocation
267 method that is only available in one of the input formats. For
268 instance, Oasys provides a byte relocation format. A relocation
269 record requesting this relocation type would point indirectly to a
270 routine to perform this, so the relocation may be performed on a
271 byte being written to a 68k COFF file, even though 68k COFF has no
272 such relocation type.
275 Object formats can contain, for debugging purposes, some form of
276 mapping between symbols, source line numbers, and addresses in the
277 output file. These addresses have to be relocated along with the
278 symbol information. Each symbol with an associated list of line
279 number records points to the first record of the list. The head
280 of a line number list consists of a pointer to the symbol, which
281 allows finding out the address of the function whose line number
282 is being described. The rest of the list is made up of pairs:
283 offsets into the section and line numbers. Any format which can
284 simply derive this information can pass it successfully between
285 formats (COFF, IEEE and Oasys).

296 A BFD has type `bfd'; objects of this type are the cornerstone of any
297 application using BFD. Using BFD consists of making references though

482 2.2.1 Type `bfd_error_type'
483 ---------------------------
485 The values returned by `bfd_get_error' are defined by the enumerated
486 type `bfd_error_type'.

521 Return the current BFD error condition.
523 2.2.1.2 `bfd_set_error'
524 .......................
527 void bfd_set_error (bfd_error_type error_tag, ...);
529 Set the BFD error condition to be ERROR_TAG. If ERROR_TAG is
530 bfd_error_on_input, then this function takes two more parameters, the
531 input bfd where the error occurred, and the bfd_error_type error.
537 const char *bfd_errmsg (bfd_error_type error_tag);
539 Return a string describing the error ERROR_TAG, or the system error if
540 ERROR_TAG is `bfd_error_system_call'.
546 void bfd_perror (const char *message);
548 Print to the standard error stream a string describing the last BFD
549 error that occurred, or the last system error if the last BFD error was
550 a system call failure. If MESSAGE is non-NULL and non-empty, the error
551 string printed is preceded by MESSAGE, a colon, and a space. It is
552 followed by a newline.
554 2.2.2 BFD error handler
555 -----------------------
557 Some BFD functions want to print messages describing the problem. They
558 call a BFD error handler function. This function may be overridden by

566 2.2.2.1 `bfd_set_error_handler'
567 ...............................
570 bfd_error_handler_type bfd_set_error_handler (bfd_error_handler_type);
572 Set the BFD error handler function. Returns the previous function.
574 2.2.2.2 `bfd_set_error_program_name'
575 ....................................
578 void bfd_set_error_program_name (const char *);
580 Set the program name to use when printing a BFD error. This is printed
581 before the error message followed by a colon and space. The string
582 must not be changed after it is passed to this function.
584 2.2.2.3 `bfd_get_error_handler'
585 ...............................
588 bfd_error_handler_type bfd_get_error_handler (void);
590 Return the BFD error handler function.
595 2.3.1 Miscellaneous functions
596 -----------------------------
598 2.3.1.1 `bfd_get_reloc_upper_bound'
599 ...................................
602 long bfd_get_reloc_upper_bound (bfd *abfd, asection *sect);
604 Return the number of bytes required to store the relocation information
605 associated with section SECT attached to bfd ABFD. If an error occurs,
608 2.3.1.2 `bfd_canonicalize_reloc'
609 ................................
612 long bfd_canonicalize_reloc
613 (bfd *abfd, asection *sec, arelent **loc, asymbol **syms);
615 Call the back end associated with the open BFD ABFD and translate the
616 external form of the relocation information attached to SEC into the
617 internal canonical form. Place the table into memory at LOC, which has
618 been preallocated, usually by a call to `bfd_get_reloc_upper_bound'.
619 Returns the number of relocs, or -1 on error.
621 The SYMS table is also needed for horrible internal magic reasons.
623 2.3.1.3 `bfd_set_reloc'
624 .......................
628 (bfd *abfd, asection *sec, arelent **rel, unsigned int count);
630 Set the relocation pointer and count within section SEC to the values
631 REL and COUNT. The argument ABFD is ignored.
633 2.3.1.4 `bfd_set_file_flags'
634 ............................
637 bfd_boolean bfd_set_file_flags (bfd *abfd, flagword flags);
639 Set the flag word in the BFD ABFD to the value FLAGS.
642 * `bfd_error_wrong_format' - The target bfd was not of object format.
644 * `bfd_error_invalid_operation' - The target bfd was open for
647 * `bfd_error_invalid_operation' - The flag word contained a bit
648 which was not applicable to the type of file. E.g., an attempt
649 was made to set the `D_PAGED' bit on a BFD format which does not
650 support demand paging.
652 2.3.1.5 `bfd_get_arch_size'
653 ...........................
656 int bfd_get_arch_size (bfd *abfd);
658 Returns the architecture address size, in bits, as determined by the
659 object file's format. For ELF, this information is included in the
663 Returns the arch size in bits if known, `-1' otherwise.
665 2.3.1.6 `bfd_get_sign_extend_vma'
666 .................................
669 int bfd_get_sign_extend_vma (bfd *abfd);
671 Indicates if the target architecture "naturally" sign extends an
672 address. Some architectures implicitly sign extend address values when
673 they are converted to types larger than the size of an address. For
674 instance, bfd_get_start_address() will return an address sign extended
675 to fill a bfd_vma when this is the case.
678 Returns `1' if the target architecture is known to sign extend
679 addresses, `0' if the target architecture is known to not sign extend
680 addresses, and `-1' otherwise.
682 2.3.1.7 `bfd_set_start_address'
683 ...............................
686 bfd_boolean bfd_set_start_address (bfd *abfd, bfd_vma vma);
688 Make VMA the entry point of output BFD ABFD.
691 Returns `TRUE' on success, `FALSE' otherwise.
693 2.3.1.8 `bfd_get_gp_size'
694 .........................
697 unsigned int bfd_get_gp_size (bfd *abfd);
699 Return the maximum size of objects to be optimized using the GP
700 register under MIPS ECOFF. This is typically set by the `-G' argument
701 to the compiler, assembler or linker.
703 2.3.1.9 `bfd_set_gp_size'
704 .........................
707 void bfd_set_gp_size (bfd *abfd, unsigned int i);
709 Set the maximum size of objects to be optimized using the GP register
710 under ECOFF or MIPS ELF. This is typically set by the `-G' argument to
711 the compiler, assembler or linker.
713 2.3.1.10 `bfd_scan_vma'

717 bfd_vma bfd_scan_vma (const char *string, const char **end, int base);
719 Convert, like `strtoul', a numerical expression STRING into a `bfd_vma'
720 integer, and return that integer. (Though without as many bells and
721 whistles as `strtoul'.) The expression is assumed to be unsigned
722 (i.e., positive). If given a BASE, it is used as the base for
723 conversion. A base of 0 causes the function to interpret the string in
724 hex if a leading "0x" or "0X" is found, otherwise in octal if a leading
725 zero is found, otherwise in decimal.
727 If the value would overflow, the maximum `bfd_vma' value is returned.

889 2.3.1.16 `bfd_alt_mach_code'
890 ............................
893 bfd_boolean bfd_alt_mach_code (bfd *abfd, int alternative);
895 When more than one machine code number is available for the same
896 machine type, this function can be used to switch between the preferred
897 one (alternative == 0) and any others. Currently, only ELF supports
898 this feature, with up to two alternate machine codes.

912 2.3.1.17 `bfd_preserve_save'
913 ............................
916 bfd_boolean bfd_preserve_save (bfd *, struct bfd_preserve *);
918 When testing an object for compatibility with a particular target
919 back-end, the back-end object_p function needs to set up certain fields
920 in the bfd on successfully recognizing the object. This typically
921 happens in a piecemeal fashion, with failures possible at many points.
922 On failure, the bfd is supposed to be restored to its initial state,
923 which is virtually impossible. However, restoring a subset of the bfd
924 state works in practice. This function stores the subset and
925 reinitializes the bfd.
927 2.3.1.18 `bfd_preserve_restore'
928 ...............................
931 void bfd_preserve_restore (bfd *, struct bfd_preserve *);
933 This function restores bfd state saved by bfd_preserve_save. If MARKER
934 is non-NULL in struct bfd_preserve then that block and all subsequently
935 bfd_alloc'd memory is freed.
937 2.3.1.19 `bfd_preserve_finish'
938 ..............................
941 void bfd_preserve_finish (bfd *, struct bfd_preserve *);
943 This function should be called when the bfd state saved by
944 bfd_preserve_save is no longer needed. ie. when the back-end object_p
945 function returns with success.

973 Returns the common page size, in bytes, as determined by emulation.

1017 2.3.1.25 `bfd_get_mtime'
1018 ........................
1021 long bfd_get_mtime (bfd *abfd);
1023 Return the file modification time (as read from the file system, or
1024 from the archive header for archive members).
1026 2.3.1.26 `bfd_get_size'
1027 .......................
1030 long bfd_get_size (bfd *abfd);
1032 Return the file size (as read from file system) for the file associated
1035 The initial motivation for, and use of, this routine is not so we
1036 can get the exact size of the object the BFD applies to, since that
1037 might not be generally possible (archive members for example). It
1038 would be ideal if someone could eventually modify it so that such
1039 results were guaranteed.
1041 Instead, we want to ask questions like "is this NNN byte sized
1042 object I'm about to try read from file offset YYY reasonable?" As as
1043 example of where we might do this, some object formats use string
1044 tables for which the first `sizeof (long)' bytes of the table contain
1045 the size of the table itself, including the size bytes. If an
1046 application tries to read what it thinks is one of these string tables,
1047 without some way to validate the size, and for some reason the size is
1048 wrong (byte swapping error, wrong location for the string table, etc.),
1049 the only clue is likely to be a read error when it tries to read the
1050 table, or a "virtual memory exhausted" error when it tries to allocate
1051 15 bazillon bytes of space for the 15 bazillon byte table it is about
1052 to read. This function at least allows us to answer the question, "is
1053 the size reasonable?".

1074 File: bfd.info, Node: Memory Usage, Next: Initialization, Prev: BFD front end, Up: BFD front end
1079 BFD keeps all of its internal structures in obstacks. There is one
1080 obstack per open BFD file, into which the current state is stored. When
1081 a BFD is closed, the obstack is deleted, and so everything which has
1082 been allocated by BFD for the closing file is thrown away.
1084 BFD does not free anything created by an application, but pointers
1085 into `bfd' structures become invalid on a `bfd_close'; for example,
1086 after a `bfd_close' the vector passed to `bfd_canonicalize_symtab' is
1087 still around, since it has been allocated by the application, but the
1088 data that it pointed to are lost.
1090 The general rule is to not close a BFD until all operations dependent
1091 upon data from the BFD have been completed, or all the data from within
1092 the file has been copied. To help with the management of memory, there
1093 is a function (`bfd_alloc_size') which returns the number of bytes in
1094 obstacks associated with the supplied BFD. This could be used to select
1095 the greediest open BFD, close it to reclaim the memory, perform some
1096 operation and reopen the BFD again, to get a fresh copy of the data

1105 2.5.1 Initialization functions
1106 ------------------------------
1108 These are the functions that handle initializing a BFD.
1114 void bfd_init (void);
1116 This routine must be called before any other BFD function to initialize
1117 magical internal data structures.

1125 The raw data contained within a BFD is maintained through the section
1126 abstraction. A single BFD may have any number of sections. It keeps
1127 hold of them by pointing to the first; each one points to the next in
1130 Sections are supported in BFD in `section.c'.

1137 * section prototypes::
1140 File: bfd.info, Node: Section Input, Next: Section Output, Prev: Sections, Up: Sections
1145 When a BFD is opened for reading, the section structures are created
1146 and attached to the BFD.
1148 Each section has a name which describes the section in the outside
1149 world--for example, `a.out' would contain at least three sections,
1150 called `.text', `.data' and `.bss'.
1152 Names need not be unique; for example a COFF file may have several
1153 sections named `.data'.
1155 Sometimes a BFD will contain more than the "natural" number of
1156 sections. A back end may attach other sections containing constructor
1157 data, or an application may add a section (using `bfd_make_section') to
1158 the sections attached to an already open BFD. For example, the linker
1159 creates an extra section `COMMON' for each input file's BFD to hold
1160 information about common storage.
1162 The raw data is not necessarily read in when the section descriptor
1163 is created. Some targets may leave the data in place until a
1164 `bfd_get_section_contents' call is made. Other back ends may read in
1165 all the data at once. For example, an S-record file has to be read
1166 once to determine the size of the data. An IEEE-695 file doesn't
1167 contain raw data in sections, but data and relocation expressions
1168 intermixed, so the data area has to be parsed to get out the data and

1174 2.6.2 Section output
1175 --------------------
1177 To write a new object style BFD, the various sections to be written
1178 have to be created. They are attached to the BFD in the same way as
1179 input sections; data is written to the sections using
1180 `bfd_set_section_contents'.
1182 Any program that creates or combines sections (e.g., the assembler
1183 and linker) must use the `asection' fields `output_section' and
1184 `output_offset' to indicate the file sections to which each section
1185 must be written. (If the section is being created from scratch,
1186 `output_section' should probably point to the section itself and
1187 `output_offset' should probably be zero.)
1189 The data to be written comes from input sections attached (via
1190 `output_section' pointers) to the output sections. The output section
1191 structure can be considered a filter for the input section: the output
1192 section determines the vma of the output data and the name, but the
1193 input section determines the offset into the output section of the data
1196 E.g., to create a section "O", starting at 0x100, 0x123 long,
1197 containing two subsections, "A" at offset 0x0 (i.e., at vma 0x100) and
1198 "B" at offset 0x20 (i.e., at vma 0x120) the `asection' structures would
1204 output_section -----------> section name "O"
1206 section name "B" | size 0x123
1207 output_offset 0x20 |
1209 output_section --------|
1214 The data within a section is stored in a "link_order". These are much
1215 like the fixups in `gas'. The link_order abstraction allows a section
1216 to grow and shrink within itself.
1218 A link_order knows how big it is, and which is the next link_order
1219 and where the raw data for it is; it also points to a list of
1220 relocations which apply to it.
1222 The link_order is used by the linker to perform relaxing on final
1223 code. The compiler creates code which is as big as necessary to make
1224 it work without relaxing, and the user can select whether to relax.
1225 Sometimes relaxing takes a lot of time. The linker runs around the
1226 relocations to see if any are attached to data which can be shrunk, if
1227 so it does it on a link_order by link_order basis.

1762 2.6.5 Section prototypes
1763 ------------------------
1765 These are the functions exported by the section handling part of BFD.
1767 2.6.5.1 `bfd_section_list_clear'
1768 ................................
1771 void bfd_section_list_clear (bfd *);
1773 Clears the section list, and also resets the section count and hash
1776 2.6.5.2 `bfd_get_section_by_name'
1777 .................................
1780 asection *bfd_get_section_by_name (bfd *abfd, const char *name);
1782 Run through ABFD and return the one of the `asection's whose name
1783 matches NAME, otherwise `NULL'. *Note Sections::, for more information.
1785 This should only be used in special cases; the normal way to process
1786 all sections of a given name is to use `bfd_map_over_sections' and
1787 `strcmp' on the name (or better yet, base it on the section flags or
1788 something else) for each section.
1790 2.6.5.3 `bfd_get_section_by_name_if'
1791 ....................................
1794 asection *bfd_get_section_by_name_if
1797 bfd_boolean (*func) (bfd *abfd, asection *sect, void *obj),
1800 Call the provided function FUNC for each section attached to the BFD
1801 ABFD whose name matches NAME, passing OBJ as an argument. The function
1802 will be called as if by
1804 func (abfd, the_section, obj);
1806 It returns the first section for which FUNC returns true, otherwise
1809 2.6.5.4 `bfd_get_unique_section_name'
1810 .....................................
1813 char *bfd_get_unique_section_name
1814 (bfd *abfd, const char *templat, int *count);
1816 Invent a section name that is unique in ABFD by tacking a dot and a
1817 digit suffix onto the original TEMPLAT. If COUNT is non-NULL, then it
1818 specifies the first number tried as a suffix to generate a unique name.
1819 The value pointed to by COUNT will be incremented in this case.
1821 2.6.5.5 `bfd_make_section_old_way'
1822 ..................................
1825 asection *bfd_make_section_old_way (bfd *abfd, const char *name);
1827 Create a new empty section called NAME and attach it to the end of the
1828 chain of sections for the BFD ABFD. An attempt to create a section with
1829 a name which is already in use returns its pointer without changing the
1832 It has the funny name since this is the way it used to be before it
1835 Possible errors are:
1836 * `bfd_error_invalid_operation' - If output has already started for
1839 * `bfd_error_no_memory' - If memory allocation fails.
1841 2.6.5.6 `bfd_make_section_anyway_with_flags'
1842 ............................................
1845 asection *bfd_make_section_anyway_with_flags
1846 (bfd *abfd, const char *name, flagword flags);
1848 Create a new empty section called NAME and attach it to the end of the
1849 chain of sections for ABFD. Create a new section even if there is
1850 already a section with that name. Also set the attributes of the new
1851 section to the value FLAGS.
1853 Return `NULL' and set `bfd_error' on error; possible errors are:
1854 * `bfd_error_invalid_operation' - If output has already started for
1857 * `bfd_error_no_memory' - If memory allocation fails.
1859 2.6.5.7 `bfd_make_section_anyway'
1860 .................................
1863 asection *bfd_make_section_anyway (bfd *abfd, const char *name);
1865 Create a new empty section called NAME and attach it to the end of the
1866 chain of sections for ABFD. Create a new section even if there is
1867 already a section with that name.
1869 Return `NULL' and set `bfd_error' on error; possible errors are:
1870 * `bfd_error_invalid_operation' - If output has already started for
1873 * `bfd_error_no_memory' - If memory allocation fails.
1875 2.6.5.8 `bfd_make_section_with_flags'
1876 .....................................
1879 asection *bfd_make_section_with_flags
1880 (bfd *, const char *name, flagword flags);
1882 Like `bfd_make_section_anyway', but return `NULL' (without calling
1883 bfd_set_error ()) without changing the section chain if there is
1884 already a section named NAME. Also set the attributes of the new
1885 section to the value FLAGS. If there is an error, return `NULL' and set
1888 2.6.5.9 `bfd_make_section'
1889 ..........................
1892 asection *bfd_make_section (bfd *, const char *name);
1894 Like `bfd_make_section_anyway', but return `NULL' (without calling
1895 bfd_set_error ()) without changing the section chain if there is
1896 already a section named NAME. If there is an error, return `NULL' and
1899 2.6.5.10 `bfd_set_section_flags'
1900 ................................
1903 bfd_boolean bfd_set_section_flags
1904 (bfd *abfd, asection *sec, flagword flags);
1906 Set the attributes of the section SEC in the BFD ABFD to the value
1907 FLAGS. Return `TRUE' on success, `FALSE' on error. Possible error
1910 * `bfd_error_invalid_operation' - The section cannot have one or
1911 more of the attributes requested. For example, a .bss section in
1912 `a.out' may not have the `SEC_HAS_CONTENTS' field set.
1914 2.6.5.11 `bfd_map_over_sections'
1915 ................................
1918 void bfd_map_over_sections
1920 void (*func) (bfd *abfd, asection *sect, void *obj),
1923 Call the provided function FUNC for each section attached to the BFD
1924 ABFD, passing OBJ as an argument. The function will be called as if by
1926 func (abfd, the_section, obj);
1928 This is the preferred method for iterating over sections; an
1929 alternative would be to use a loop:
1932 for (p = abfd->sections; p != NULL; p = p->next)
1935 2.6.5.12 `bfd_sections_find_if'
1936 ...............................
1939 asection *bfd_sections_find_if
1941 bfd_boolean (*operation) (bfd *abfd, asection *sect, void *obj),
1944 Call the provided function OPERATION for each section attached to the
1945 BFD ABFD, passing OBJ as an argument. The function will be called as if
1948 operation (abfd, the_section, obj);
1950 It returns the first section for which OPERATION returns true.
1952 2.6.5.13 `bfd_set_section_size'
1953 ...............................
1956 bfd_boolean bfd_set_section_size
1957 (bfd *abfd, asection *sec, bfd_size_type val);
1959 Set SEC to the size VAL. If the operation is ok, then `TRUE' is
1960 returned, else `FALSE'.
1962 Possible error returns:
1963 * `bfd_error_invalid_operation' - Writing has started to the BFD, so
1964 setting the size is invalid.
1966 2.6.5.14 `bfd_set_section_contents'
1967 ...................................
1970 bfd_boolean bfd_set_section_contents
1971 (bfd *abfd, asection *section, const void *data,
1972 file_ptr offset, bfd_size_type count);
1974 Sets the contents of the section SECTION in BFD ABFD to the data
1975 starting in memory at DATA. The data is written to the output section
1976 starting at offset OFFSET for COUNT octets.
1978 Normally `TRUE' is returned, else `FALSE'. Possible error returns
1980 * `bfd_error_no_contents' - The output section does not have the
1981 `SEC_HAS_CONTENTS' attribute, so nothing can be written to it.
1984 This routine is front end to the back end function
1985 `_bfd_set_section_contents'.
1987 2.6.5.15 `bfd_get_section_contents'
1988 ...................................
1991 bfd_boolean bfd_get_section_contents
1992 (bfd *abfd, asection *section, void *location, file_ptr offset,
1993 bfd_size_type count);
1995 Read data from SECTION in BFD ABFD into memory starting at LOCATION.
1996 The data is read at an offset of OFFSET from the start of the input
1997 section, and is read for COUNT bytes.
1999 If the contents of a constructor with the `SEC_CONSTRUCTOR' flag set
2000 are requested or if the section does not have the `SEC_HAS_CONTENTS'
2001 flag set, then the LOCATION is filled with zeroes. If no errors occur,
2002 `TRUE' is returned, else `FALSE'.
2004 2.6.5.16 `bfd_malloc_and_get_section'
2005 .....................................
2008 bfd_boolean bfd_malloc_and_get_section
2009 (bfd *abfd, asection *section, bfd_byte **buf);
2011 Read all data from SECTION in BFD ABFD into a buffer, *BUF, malloc'd by
2014 2.6.5.17 `bfd_copy_private_section_data'
2015 ........................................
2018 bfd_boolean bfd_copy_private_section_data
2019 (bfd *ibfd, asection *isec, bfd *obfd, asection *osec);
2021 Copy private section information from ISEC in the BFD IBFD to the
2022 section OSEC in the BFD OBFD. Return `TRUE' on success, `FALSE' on

2054 BFD tries to maintain as much symbol information as it can when it
2055 moves information from file to file. BFD passes information to
2056 applications though the `asymbol' structure. When the application
2057 requests the symbol table, BFD reads the table in the native form and
2058 translates parts of it into the internal format. To maintain more than
2059 the information passed to applications, some targets keep some
2060 information "behind the scenes" in a structure only the particular back
2061 end knows about. For example, the coff back end keeps the original
2062 symbol table structure as well as the canonical structure when a BFD is
2063 read in. On output, the coff back end can reconstruct the output symbol
2064 table so that no information is lost, even information unique to coff
2065 which BFD doesn't know or understand. If a coff symbol table were read,
2066 but were written through an a.out back end, all the coff specific
2067 information would be lost. The symbol table of a BFD is not necessarily
2068 read in until a canonicalize request is made. Then the BFD back end
2069 fills in a table provided by the application with pointers to the
2070 canonical information. To output symbols, the application provides BFD
2071 with a table of pointers to pointers to `asymbol's. This allows
2072 applications like the linker to output a symbol as it was read, since
2073 the "behind the scenes" information will be still available.

2086 2.7.1 Reading symbols
2087 ---------------------
2089 There are two stages to reading a symbol table from a BFD: allocating
2090 storage, and the actual reading process. This is an excerpt from an
2091 application which reads the symbol table:
2093 long storage_needed;
2094 asymbol **symbol_table;
2095 long number_of_symbols;
2098 storage_needed = bfd_get_symtab_upper_bound (abfd);
2100 if (storage_needed < 0)
2103 if (storage_needed == 0)
2106 symbol_table = xmalloc (storage_needed);
2109 bfd_canonicalize_symtab (abfd, symbol_table);
2111 if (number_of_symbols < 0)
2114 for (i = 0; i < number_of_symbols; i++)
2115 process_symbol (symbol_table[i]);
2117 All storage for the symbols themselves is in an objalloc connected
2118 to the BFD; it is freed when the BFD is closed.

2123 2.7.2 Writing symbols
2124 ---------------------
2126 Writing of a symbol table is automatic when a BFD open for writing is
2127 closed. The application attaches a vector of pointers to pointers to
2128 symbols to the BFD being written, and fills in the symbol count. The
2129 close and cleanup code reads through the table provided and performs
2130 all the necessary operations. The BFD output code must always be
2131 provided with an "owned" symbol: one which has come from another BFD,
2132 or one which has been created using `bfd_make_empty_symbol'. Here is an
2133 example showing the creation of a symbol table with only one element:
2142 abfd = bfd_openw ("foo","a.out-sunos-big");
2143 bfd_set_format (abfd, bfd_object);
2144 new = bfd_make_empty_symbol (abfd);
2145 new->name = "dummy_symbol";
2146 new->section = bfd_make_section_old_way (abfd, ".text");
2147 new->flags = BSF_GLOBAL;
2148 new->value = 0x12345;
2153 bfd_set_symtab (abfd, ptrs, 1);
2160 00012345 A dummy_symbol
2162 Many formats cannot represent arbitrary symbol information; for
2163 instance, the `a.out' object format does not allow an arbitrary number
2164 of sections. A symbol pointing to a section which is not one of
2165 `.text', `.data' or `.bss' cannot be described.
2168 File: bfd.info, Node: Mini Symbols, Next: typedef asymbol, Prev: Writing Symbols, Up: Symbols
2173 Mini symbols provide read-only access to the symbol table. They use
2174 less memory space, but require more time to access. They can be useful
2175 for tools like nm or objdump, which may have to handle symbol tables of
2176 extremely large executables.
2178 The `bfd_read_minisymbols' function will read the symbols into
2179 memory in an internal form. It will return a `void *' pointer to a
2180 block of memory, a symbol count, and the size of each symbol. The
2181 pointer is allocated using `malloc', and should be freed by the caller
2182 when it is no longer needed.
2184 The function `bfd_minisymbol_to_symbol' will take a pointer to a
2185 minisymbol, and a pointer to a structure returned by
2186 `bfd_make_empty_symbol', and return a `asymbol' structure. The return
2187 value may or may not be the same as the value from
2188 `bfd_make_empty_symbol' which was passed in.

2489 An archive (or library) is just another BFD. It has a symbol table,
2490 although there's not much a user program will do with it.
2492 The big difference between an archive BFD and an ordinary BFD is
2493 that the archive doesn't have sections. Instead it has a chain of BFDs
2494 that are considered its contents. These BFDs can be manipulated like
2495 any other. The BFDs contained in an archive opened for reading will
2496 all be opened for reading. You may put either input or output BFDs
2497 into an archive opened for output; they will be handled correctly when
2498 the archive is closed.
2500 Use `bfd_openr_next_archived_file' to step through the contents of
2501 an archive opened for input. You don't have to read the entire archive
2502 if you don't want to! Read it until you find what you want.
2504 Archive contents of output BFDs are chained through the `next'
2505 pointer in a BFD. The first one is findable through the `archive_head'
2506 slot of the archive. Set it with `bfd_set_archive_head' (q.v.). A
2507 given BFD may be in only one open output archive at a time.
2509 As expected, the BFD archive code is more general than the archive
2510 code of any given environment. BFD archives may contain files of
2511 different formats (e.g., a.out and coff) and even different
2512 architectures. You may even place archives recursively into archives!
2514 This can cause unexpected confusion, since some archive formats are
2515 more expressive than others. For instance, Intel COFF archives can
2516 preserve long filenames; SunOS a.out archives cannot. If you move a
2517 file from the first to the second format and back again, the filename
2518 may be truncated. Likewise, different a.out environments have different
2519 conventions as to how they truncate filenames, whether they preserve
2520 directory names in filenames, etc. When interoperating with native
2521 tools, be sure your files are homogeneous.
2523 Beware: most of these formats do not react well to the presence of
2524 spaces in filenames. We do the best we can, but can't always handle
2525 this case due to restrictions in the format of archives. Many Unix
2526 utilities are braindead in regards to spaces and such in filenames
2527 anyway, so this shouldn't be much of a restriction.
2529 Archives are supported in BFD in `archive.c'.

2538 symindex bfd_get_next_mapent
2539 (bfd *abfd, symindex previous, carsym **sym);
2541 Step through archive ABFD's symbol table (if it has one). Successively
2542 update SYM with the next symbol's information, returning that symbol's
2543 (internal) index into the symbol table.
2545 Supply `BFD_NO_MORE_SYMBOLS' as the PREVIOUS entry to get the first
2546 one; returns `BFD_NO_MORE_SYMBOLS' when you've already got the last one.
2548 A `carsym' is a canonical archive symbol. The only user-visible
2549 element is its name, a null-terminated string.

2566 Provided a BFD, ARCHIVE, containing an archive and NULL, open an input
2567 BFD on the first contained element and returns that. Subsequent calls
2568 should pass the archive and the previous return value to return a
2569 created BFD to the next contained element. NULL is returned when there

2578 A format is a BFD concept of high level file contents type. The formats
2579 supported by BFD are:
2582 The BFD may contain data, symbols, relocations and debug info.
2585 The BFD contains other BFDs and an optional index.
2588 The BFD contains the result of an executable core dump.
2590 2.9.1 File format functions
2591 ---------------------------
2593 2.9.1.1 `bfd_check_format'
2594 ..........................
2597 bfd_boolean bfd_check_format (bfd *abfd, bfd_format format);
2599 Verify if the file attached to the BFD ABFD is compatible with the
2600 format FORMAT (i.e., one of `bfd_object', `bfd_archive' or `bfd_core').
2602 If the BFD has been set to a specific target before the call, only
2603 the named target and format combination is checked. If the target has
2604 not been set, or has been set to `default', then all the known target
2605 backends is interrogated to determine a match. If the default target
2606 matches, it is used. If not, exactly one target must recognize the
2607 file, or an error results.
2609 The function returns `TRUE' on success, otherwise `FALSE' with one
2610 of the following error codes:
2612 * `bfd_error_invalid_operation' - if `format' is not one of
2613 `bfd_object', `bfd_archive' or `bfd_core'.
2615 * `bfd_error_system_call' - if an error occured during a read - even
2616 some file mismatches can cause bfd_error_system_calls.
2618 * `file_not_recognised' - none of the backends recognised the file
2621 * `bfd_error_file_ambiguously_recognized' - more than one backend
2622 recognised the file format.
2624 2.9.1.2 `bfd_check_format_matches'
2625 ..................................
2628 bfd_boolean bfd_check_format_matches
2629 (bfd *abfd, bfd_format format, char ***matching);
2631 Like `bfd_check_format', except when it returns FALSE with `bfd_errno'
2632 set to `bfd_error_file_ambiguously_recognized'. In that case, if
2633 MATCHING is not NULL, it will be filled in with a NULL-terminated list
2634 of the names of the formats that matched, allocated with `malloc'.
2635 Then the user may choose a format and try again.
2637 When done with the list that MATCHING points to, the caller should
2640 2.9.1.3 `bfd_set_format'
2641 ........................
2644 bfd_boolean bfd_set_format (bfd *abfd, bfd_format format);
2646 This function sets the file format of the BFD ABFD to the format
2647 FORMAT. If the target set in the BFD does not support the format
2648 requested, the format is invalid, or the BFD is not open for writing,
2649 then an error occurs.
2651 2.9.1.4 `bfd_format_string'
2652 ...........................
2655 const char *bfd_format_string (bfd_format format);
2657 Return a pointer to a const string `invalid', `object', `archive',
2658 `core', or `unknown', depending upon the value of FORMAT.

2666 BFD maintains relocations in much the same way it maintains symbols:
2667 they are left alone until required, then read in en-masse and
2668 translated into an internal form. A common routine
2669 `bfd_perform_relocation' acts upon the canonical form to do the fixup.
2671 Relocations are maintained on a per section basis, while symbols are
2672 maintained on a per BFD basis.
2674 All that a back end has to do to fit the BFD interface is to create
2675 a `struct reloc_cache_entry' for each relocation in a particular
2676 section, and fill in the right bits of the structures.

2689 This is the structure of a relocation entry:
2692 typedef enum bfd_reloc_status
2694 /* No errors detected. */
2697 /* The relocation was performed, but there was an overflow. */
2700 /* The address to relocate was not within the section supplied. */
2701 bfd_reloc_outofrange,
2703 /* Used by special functions. */
2706 /* Unsupported relocation size requested. */
2707 bfd_reloc_notsupported,
2712 /* The symbol to relocate against was undefined. */
2713 bfd_reloc_undefined,
2715 /* The relocation was performed, but may not be ok - presently
2716 generated only when linking i960 coff files with i960 b.out
2717 symbols. If this type is returned, the error_message argument
2718 to bfd_perform_relocation will be set. */
2721 bfd_reloc_status_type;
2724 typedef struct reloc_cache_entry
2726 /* A pointer into the canonical table of pointers. */
2727 struct bfd_symbol **sym_ptr_ptr;
2729 /* offset in section. */
2730 bfd_size_type address;
2732 /* addend for relocation value. */
2735 /* Pointer to how to perform the required relocation. */
2736 reloc_howto_type *howto;
2741 Here is a description of each of the fields within an `arelent':
2744 The symbol table pointer points to a pointer to the symbol
2745 associated with the relocation request. It is the pointer into the
2746 table returned by the back end's `canonicalize_symtab' action. *Note
2747 Symbols::. The symbol is referenced through a pointer to a pointer so
2748 that tools like the linker can fix up all the symbols of the same name
2749 by modifying only one pointer. The relocation routine looks in the
2750 symbol and uses the base of the section the symbol is attached to and
2751 the value of the symbol as the initial relocation offset. If the symbol
2752 pointer is zero, then the section provided is looked up.
2755 The `address' field gives the offset in bytes from the base of the
2756 section data which owns the relocation record to the first byte of
2757 relocatable information. The actual data relocated will be relative to
2758 this point; for example, a relocation type which modifies the bottom
2759 two bytes of a four byte word would not touch the first byte pointed to
2760 in a big endian world.
2763 The `addend' is a value provided by the back end to be added (!) to
2764 the relocation offset. Its interpretation is dependent upon the howto.
2765 For example, on the 68k the code:
2770 return foo[0x12345678];
2773 Could be compiled into:
2781 This could create a reloc pointing to `foo', but leave the offset in
2782 the data, something like:
2784 RELOCATION RECORDS FOR [.text]:
2788 00000000 4e56 fffc ; linkw fp,#-4
2789 00000004 1039 1234 5678 ; moveb @#12345678,d0
2790 0000000a 49c0 ; extbl d0
2791 0000000c 4e5e ; unlk fp
2794 Using coff and an 88k, some instructions don't have enough space in
2795 them to represent the full address range, and pointers have to be
2796 loaded in two parts. So you'd get something like:
2798 or.u r13,r0,hi16(_foo+0x12345678)
2799 ld.b r2,r13,lo16(_foo+0x12345678)
2802 This should create two relocs, both pointing to `_foo', and with
2803 0x12340000 in their addend field. The data would consist of:
2805 RELOCATION RECORDS FOR [.text]:
2807 00000002 HVRT16 _foo+0x12340000
2808 00000006 LVRT16 _foo+0x12340000
2810 00000000 5da05678 ; or.u r13,r0,0x5678
2811 00000004 1c4d5678 ; ld.b r2,r13,0x5678
2812 00000008 f400c001 ; jmp r1
2814 The relocation routine digs out the value from the data, adds it to
2815 the addend to get the original offset, and then adds the value of
2816 `_foo'. Note that all 32 bits have to be kept around somewhere, to cope
2817 with carry from bit 15 to bit 16.
2819 One further example is the sparc and the a.out format. The sparc has
2820 a similar problem to the 88k, in that some instructions don't have room
2821 for an entire offset, but on the sparc the parts are created in odd
2822 sized lumps. The designers of the a.out format chose to not use the
2823 data within the section for storing part of the offset; all the offset
2824 is kept within the reloc. Anything in the data should be ignored.
2827 sethi %hi(_foo+0x12345678),%g2
2828 ldsb [%g2+%lo(_foo+0x12345678)],%i0
2832 Both relocs contain a pointer to `foo', and the offsets contain junk.
2834 RELOCATION RECORDS FOR [.text]:
2836 00000004 HI22 _foo+0x12345678
2837 00000008 LO10 _foo+0x12345678
2839 00000000 9de3bf90 ; save %sp,-112,%sp
2840 00000004 05000000 ; sethi %hi(_foo+0),%g2
2841 00000008 f048a000 ; ldsb [%g2+%lo(_foo+0)],%i0
2842 0000000c 81c7e008 ; ret
2843 00000010 81e80000 ; restore
2846 The `howto' field can be imagined as a relocation instruction. It is
2847 a pointer to a structure which contains information on what to do with
2848 all of the other information in the reloc record and data section. A
2849 back end would normally have a relocation instruction set and turn
2850 relocations into pointers to the correct structure on input - but it
2851 would be possible to create each howto field on demand.

2937 distinction between USE_REL and USE_RELA (though the code checks

2939 addend is recorded with the section contents; when performing a
2940 partial link (ld -r) the section contents (the data) will be
2941 modified. The value of this field is FALSE if addends are

2943 a partial link the relocation will be modified.
2944 All relocations for all ELF USE_RELA targets should set this field
2945 to FALSE (values of TRUE should be looked on with suspicion).
2946 However, the converse is not true: not all relocations of all ELF
2947 USE_REL targets set this field to TRUE. Why this is so is peculiar
2948 to each particular target. For relocs that aren't used in partial
2949 links (e.g. GOT stuff) it doesn't matter what this is set to. */

2955 dst_mask to extract the addend from the section contents. If
2956 relocations do have an addend in the reloc, eg. ELF USE_RELA, this
2957 field should be zero. Non-zero values for ELF USE_RELA targets are

2970 Some formats leave the displacement part of an instruction
2971 empty (e.g., m88k bcs); this flag signals the fact. */

2981 { (unsigned) C, R, S, B, P, BI, O, SF, NAME, INPLACE, MASKSRC, MASKDST, PC }

3013 2.10.1.4 `bfd_get_reloc_size'
3014 .............................
3017 unsigned int bfd_get_reloc_size (reloc_howto_type *);
3019 For a reloc_howto_type that operates on a fixed number of bytes, this
3020 returns the number of bytes operated on.
3022 2.10.1.5 `arelent_chain'
3023 ........................
3026 How relocs are tied together in an `asection':
3027 typedef struct relent_chain
3030 struct relent_chain *next;
3034 2.10.1.6 `bfd_check_overflow'
3035 .............................
3038 bfd_reloc_status_type bfd_check_overflow
3039 (enum complain_overflow how,
3040 unsigned int bitsize,
3041 unsigned int rightshift,
3042 unsigned int addrsize,
3043 bfd_vma relocation);
3045 Perform overflow checking on RELOCATION which has BITSIZE significant
3046 bits and will be shifted right by RIGHTSHIFT bits, on a machine with
3047 addresses containing ADDRSIZE significant bits. The result is either of
3048 `bfd_reloc_ok' or `bfd_reloc_overflow'.
3050 2.10.1.7 `bfd_perform_relocation'
3051 .................................
3054 bfd_reloc_status_type bfd_perform_relocation
3056 arelent *reloc_entry,
3058 asection *input_section,
3060 char **error_message);
3062 If OUTPUT_BFD is supplied to this function, the generated image will be
3063 relocatable; the relocations are copied to the output file after they
3064 have been changed to reflect the new state of the world. There are two
3065 ways of reflecting the results of partial linkage in an output file: by
3066 modifying the output data in place, and by modifying the relocation
3067 record. Some native formats (e.g., basic a.out and basic coff) have no
3068 way of specifying an addend in the relocation type, so the addend has
3069 to go in the output data. This is no big deal since in these formats
3070 the output data slot will always be big enough for the addend. Complex
3071 reloc types with addends were invented to solve just this problem. The
3072 ERROR_MESSAGE argument is set to an error message if this return
3073 `bfd_reloc_dangerous'.
3075 2.10.1.8 `bfd_install_relocation'
3076 .................................
3079 bfd_reloc_status_type bfd_install_relocation
3081 arelent *reloc_entry,
3082 void *data, bfd_vma data_start,
3083 asection *input_section,
3084 char **error_message);
3086 This looks remarkably like `bfd_perform_relocation', except it does not
3087 expect that the section contents have been filled in. I.e., it's
3088 suitable for use when creating, rather than applying a relocation.
3090 For now, this function should be considered reserved for the
3094 File: bfd.info, Node: howto manager, Prev: typedef arelent, Up: Relocations
3096 2.10.2 The howto manager
3097 ------------------------
3099 When an application wants to create a relocation, but doesn't know what
3100 the target machine might call it, it can find out by using this bit of
3103 2.10.2.1 `bfd_reloc_code_type'
3104 ..............................
3107 The insides of a reloc code. The idea is that, eventually, there will
3108 be one enumerator for every type of relocation we ever do. Pass one of
3109 these values to `bfd_reloc_type_lookup', and it'll return a howto
3112 This does mean that the application must determine the correct
3113 enumerator value; you can't get a howto pointer from a random set of
3116 Here are the possible values for `enum bfd_reloc_code_real':

3133 PC-relative relocations. Sometimes these are relative to the
3134 address of the relocation itself; sometimes they are relative to
3135 the start of the section containing the relocation. It depends on
3136 the specific target.

3188 displacement (<<32_PCREL_S2>> - 32 bits, shifted 2) is used on the

3302 Alpha ECOFF and ELF relocations. Some of these treat the symbol or
3303 "addend" in some special way. For GPDISP_HI16 ("gpdisp")
3304 relocations, the symbol is ignored when writing; when reading, it
3305 will be the absolute section symbol. The addend is the
3306 displacement in bytes of the "lda" instruction from the "ldah"
3307 instruction (which is at the address of this reloc).
3309 -- : BFD_RELOC_ALPHA_GPDISP_LO16
3310 For GPDISP_LO16 ("ignore") relocations, the symbol is handled as
3311 with GPDISP_HI16 relocs. The addend is ignored when writing the
3312 relocations out, and is filled in with the file's GP value on
3313 reading, for convenience.
3315 -- : BFD_RELOC_ALPHA_GPDISP
3316 The ELF GPDISP relocation is exactly the same as the GPDISP_HI16
3317 relocation except that there is no accompanying GPDISP_LO16
3320 -- : BFD_RELOC_ALPHA_LITERAL
3321 -- : BFD_RELOC_ALPHA_ELF_LITERAL
3322 -- : BFD_RELOC_ALPHA_LITUSE
3323 The Alpha LITERAL/LITUSE relocs are produced by a symbol reference;
3324 the assembler turns it into a LDQ instruction to load the address
3325 of the symbol, and then fills in a register in the real
3328 The LITERAL reloc, at the LDQ instruction, refers to the .lita
3329 section symbol. The addend is ignored when writing, but is filled
3330 in with the file's GP value on reading, for convenience, as with
3331 the GPDISP_LO16 reloc.
3333 The ELF_LITERAL reloc is somewhere between 16_GOTOFF and
3334 GPDISP_LO16. It should refer to the symbol to be referenced, as
3335 with 16_GOTOFF, but it generates output not based on the position
3336 within the .got section, but relative to the GP value chosen for
3337 the file during the final link stage.
3339 The LITUSE reloc, on the instruction using the loaded address,
3340 gives information to the linker that it might be able to use to
3341 optimize away some literal section references. The symbol is
3342 ignored (read as the absolute section symbol), and the "addend"
3343 indicates the type of instruction using the register: 1 - "memory"
3344 fmt insn 2 - byte-manipulation (byte offset reg) 3 - jsr (target
3347 -- : BFD_RELOC_ALPHA_HINT
3348 The HINT relocation indicates a value that should be filled into
3349 the "hint" field of a jmp/jsr/ret instruction, for possible branch-
3350 prediction logic which may be provided on some processors.
3352 -- : BFD_RELOC_ALPHA_LINKAGE
3353 The LINKAGE relocation outputs a linkage pair in the object file,
3354 which is filled by the linker.

3357 The CODEADDR relocation outputs a STO_CA in the object file, which
3358 is filled by the linker.

4680 relocation's symbol should be the parent class' vtable, and the
4681 relocation should be located at the child vtable.
4683 VTABLE_ENTRY is a zero-space relocation that describes the use of a
4684 virtual function table entry. The reloc's symbol should refer to
4685 the table of the class mentioned in the code. Off of that base,
4686 an offset describes the entry that is being used. For Rela hosts,
4687 this offset is stored in the reloc's addend. For Rel hosts, we
4688 are forced to put this offset in the reloc's section offset.

5188 2.11.1 Core file functions
5189 --------------------------
5192 These are functions pertaining to core files.
5194 2.11.1.1 `bfd_core_file_failing_command'
5195 ........................................
5198 const char *bfd_core_file_failing_command (bfd *abfd);
5200 Return a read-only string explaining which program was running when it
5201 failed and produced the core file ABFD.
5203 2.11.1.2 `bfd_core_file_failing_signal'
5204 .......................................
5207 int bfd_core_file_failing_signal (bfd *abfd);
5209 Returns the signal number which caused the core dump which generated
5210 the file the BFD ABFD is attached to.
5212 2.11.1.3 `core_file_matches_executable_p'
5213 .........................................
5216 bfd_boolean core_file_matches_executable_p
5217 (bfd *core_bfd, bfd *exec_bfd);
5219 Return `TRUE' if the core file attached to CORE_BFD was generated by a
5220 run of the executable file attached to EXEC_BFD, `FALSE' otherwise.
5222 2.11.1.4 `generic_core_file_matches_executable_p'
5223 .................................................
5226 bfd_boolean generic_core_file_matches_executable_p
5227 (bfd *core_bfd, bfd *exec_bfd);
5229 Return TRUE if the core file attached to CORE_BFD was generated by a
5230 run of the executable file attached to EXEC_BFD. The match is based on
5231 executable basenames only.
5233 Note: When not able to determine the core file failing command or
5234 the executable name, we still return TRUE even though we're not sure
5235 that core file and executable match. This is to avoid generating a
5236 false warning in situations where we really don't know whether they
5240 File: bfd.info, Node: Targets, Next: Architectures, Prev: Core Files, Up: BFD front end
5246 Each port of BFD to a different machine requires the creation of a
5247 target back end. All the back end provides to the root part of BFD is a
5248 structure containing pointers to functions which perform certain low
5249 level operations on files. BFD translates the applications's requests
5250 through a pointer into calls to the back end routines.
5252 When a file is opened with `bfd_openr', its format and target are
5253 unknown. BFD uses various mechanisms to determine how to interpret the
5254 file. The operations performed are:
5256 * Create a BFD by calling the internal routine `_bfd_new_bfd', then
5257 call `bfd_find_target' with the target string supplied to
5258 `bfd_openr' and the new BFD pointer.
5260 * If a null target string was provided to `bfd_find_target', look up
5261 the environment variable `GNUTARGET' and use that as the target
5264 * If the target string is still `NULL', or the target string is
5265 `default', then use the first item in the target vector as the
5266 target type, and set `target_defaulted' in the BFD to cause
5267 `bfd_check_format' to loop through all the targets. *Note
5268 bfd_target::. *Note Formats::.
5270 * Otherwise, inspect the elements in the target vector one by one,
5271 until a match on target name is found. When found, use it.
5273 * Otherwise return the error `bfd_error_invalid_target' to
5276 * `bfd_openr' attempts to open the file using `bfd_open_file', and
5278 Once the BFD has been opened and the target selected, the file
5279 format may be determined. This is done by calling `bfd_check_format' on
5280 the BFD with a suggested format. If `target_defaulted' has been set,
5281 each possible target type is tried to see if it recognizes the
5282 specified format. `bfd_check_format' returns `TRUE' when the caller
5290 File: bfd.info, Node: bfd_target, Prev: Targets, Up: Targets
5296 This structure contains everything that BFD knows about a target. It
5297 includes things like its byte order, name, and which routines to call
5298 to do various operations.
5300 Every BFD points to a target structure with its `xvec' member.
5302 The macros below are used to dispatch to functions through the
5303 `bfd_target' vector. They are used in a number of macros further down
5304 in `bfd.h', and are also used when calling various routines by hand
5305 inside the BFD implementation. The ARGLIST argument must be
5306 parenthesized; it contains all the arguments to the called function.
5308 They make the documentation (more) unpleasant to read, so if someone
5309 wants to fix this and not break the above, please do.
5310 #define BFD_SEND(bfd, message, arglist) \
5311 ((*((bfd)->xvec->message)) arglist)

5315 #define BFD_SEND(bfd, message, arglist) \
5316 (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
5317 ((*((bfd)->xvec->message)) arglist) : \
5318 (bfd_assert (__FILE__,__LINE__), NULL))
5320 For operations which index on the BFD format:
5321 #define BFD_SEND_FMT(bfd, message, arglist) \
5322 (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist)
5324 #ifdef DEBUG_BFD_SEND

5328 (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist) : \
5329 (bfd_assert (__FILE__,__LINE__), NULL))
5331 This is the structure which defines the type of BFD this is. The
5332 `xvec' member of the struct `bfd' itself points here. Each module that
5333 implements access to a different target under BFD, defines one of these.
5335 FIXME, these names should be rationalised with the names of the
5336 entry points which call them. Too bad we can't have one macro to define

5703 endianness. The function open_output() in ld/ldlang.c uses this field
5704 to find an alternative output format that is suitable.

5714 2.12.1.1 `bfd_set_default_target'
5715 .................................
5718 bfd_boolean bfd_set_default_target (const char *name);
5720 Set the default target vector to use when recognizing a BFD. This
5721 takes the name of the target, which may be a BFD target name or a
5722 configuration triplet.
5724 2.12.1.2 `bfd_find_target'
5725 ..........................
5728 const bfd_target *bfd_find_target (const char *target_name, bfd *abfd);
5730 Return a pointer to the transfer vector for the object target named
5731 TARGET_NAME. If TARGET_NAME is `NULL', choose the one in the
5732 environment variable `GNUTARGET'; if that is null or not defined, then
5733 choose the first entry in the target list. Passing in the string
5734 "default" or setting the environment variable to "default" will cause
5735 the first entry in the target list to be returned, and
5736 "target_defaulted" will be set in the BFD if ABFD isn't `NULL'. This
5737 causes `bfd_check_format' to loop over all the targets to find the one
5738 that matches the file being read.
5740 2.12.1.3 `bfd_target_list'
5741 ..........................
5744 const char ** bfd_target_list (void);
5746 Return a freshly malloced NULL-terminated vector of the names of all
5747 the valid BFD targets. Do not modify the names.
5749 2.12.1.4 `bfd_seach_for_target'
5750 ...............................
5753 const bfd_target *bfd_search_for_target
5754 (int (*search_func) (const bfd_target *, void *),
5757 Return a pointer to the first transfer vector in the list of transfer
5758 vectors maintained by BFD that produces a non-zero result when passed
5759 to the function SEARCH_FUNC. The parameter DATA is passed, unexamined,
5760 to the search function.
5763 File: bfd.info, Node: Architectures, Next: Opening and Closing, Prev: Targets, Up: BFD front end
5768 BFD keeps one atom in a BFD describing the architecture of the data
5769 attached to the BFD: a pointer to a `bfd_arch_info_type'.
5771 Pointers to structures can be requested independently of a BFD so
5772 that an architecture's information can be interrogated without access
5775 The architecture information is provided by each architecture
5776 package. The set of default architectures is selected by the macro
5777 `SELECT_ARCHITECTURES'. This is normally set up in the
5778 `config/TARGET.mt' file of your choice. If the name is not defined,
5779 then all the architectures supported are included.
5781 When BFD starts up, all the architectures are called with an
5782 initialize method. It is up to the architecture back end to insert as
5783 many items into the list of architectures as it wants to; generally
5784 this would be one for each machine and one for the default case (an
5785 item with a machine field of 0).
5787 BFD's idea of an architecture is implemented in `archures.c'.
5789 2.13.1 bfd_architecture
5790 -----------------------
5793 This enum gives the object file's CPU architecture, in a global
5794 sense--i.e., what processor family does it belong to? Another field
5795 indicates which processor within the family is in use. The machine
5796 gives a number which distinguishes different versions of the
5797 architecture, containing, for example, 2 and 3 for Intel i960 KA and
5798 i960 KB, and 68020 and 68030 for Motorola 68020 and 68030.

6191 ..................................
6194 The `bfd_default_arch_struct' is an item of `bfd_arch_info_type' which
6195 has been initialized to a fairly generic state. A BFD starts life by
6196 pointing to this structure, until the correct back end has determined
6197 the real architecture of the file.

6272 .............................
6275 const bfd_arch_info_type *bfd_get_arch_info (bfd *abfd);
6277 Return the architecture info struct in ABFD.
6279 2.13.2.15 `bfd_lookup_arch'
6280 ...........................
6283 const bfd_arch_info_type *bfd_lookup_arch
6284 (enum bfd_architecture arch, unsigned long machine);
6286 Look for the architecture info structure which matches the arguments
6287 ARCH and MACHINE. A machine of 0 matches the machine/architecture

6300 This routine is depreciated.
6302 2.13.2.17 `bfd_octets_per_byte'
6303 ...............................
6306 unsigned int bfd_octets_per_byte (bfd *abfd);
6308 Return the number of octets (8-bit quantities) per target byte (minimum
6309 addressable unit). In most cases, this will be one, but some DSP
6310 targets have 16, 32, or even 48 bits per byte.

6327 2.14 Opening and closing BFDs
6328 =============================
6330 2.14.1 Functions for opening and closing
6331 ----------------------------------------
6333 2.14.1.1 `bfd_fopen'
6334 ....................
6337 bfd *bfd_fopen (const char *filename, const char *target,
6338 const char *mode, int fd);
6340 Open the file FILENAME with the target TARGET. Return a pointer to the
6341 created BFD. If FD is not -1, then `fdopen' is used to open the file;
6342 otherwise, `fopen' is used. MODE is passed directly to `fopen' or
6345 Calls `bfd_find_target', so TARGET is interpreted as by that
6348 The new BFD is marked as cacheable iff FD is -1.
6350 If `NULL' is returned then an error has occured. Possible errors
6351 are `bfd_error_no_memory', `bfd_error_invalid_target' or `system_call'
6354 2.14.1.2 `bfd_openr'
6355 ....................
6358 bfd *bfd_openr (const char *filename, const char *target);
6360 Open the file FILENAME (using `fopen') with the target TARGET. Return
6361 a pointer to the created BFD.
6363 Calls `bfd_find_target', so TARGET is interpreted as by that
6366 If `NULL' is returned then an error has occured. Possible errors
6367 are `bfd_error_no_memory', `bfd_error_invalid_target' or `system_call'
6370 2.14.1.3 `bfd_fdopenr'
6371 ......................
6374 bfd *bfd_fdopenr (const char *filename, const char *target, int fd);
6376 `bfd_fdopenr' is to `bfd_fopenr' much like `fdopen' is to `fopen'. It
6377 opens a BFD on a file already described by the FD supplied.
6379 When the file is later `bfd_close'd, the file descriptor will be
6380 closed. If the caller desires that this file descriptor be cached by
6381 BFD (opened as needed, closed as needed to free descriptors for other
6382 opens), with the supplied FD used as an initial file descriptor (but
6383 subject to closure at any time), call bfd_set_cacheable(bfd, 1) on the
6384 returned BFD. The default is to assume no caching; the file descriptor
6385 will remain open until `bfd_close', and will not be affected by BFD
6386 operations on other files.
6388 Possible errors are `bfd_error_no_memory',
6389 `bfd_error_invalid_target' and `bfd_error_system_call'.
6391 2.14.1.4 `bfd_openstreamr'
6392 ..........................
6395 bfd *bfd_openstreamr (const char *, const char *, void *);
6397 Open a BFD for read access on an existing stdio stream. When the BFD
6398 is passed to `bfd_close', the stream will be closed.
6400 2.14.1.5 `bfd_openr_iovec'
6401 ..........................
6404 bfd *bfd_openr_iovec (const char *filename, const char *target,
6405 void *(*open) (struct bfd *nbfd,
6406 void *open_closure),
6408 file_ptr (*pread) (struct bfd *nbfd,
6413 int (*close) (struct bfd *nbfd,
6416 Create and return a BFD backed by a read-only STREAM. The STREAM is
6417 created using OPEN, accessed using PREAD and destroyed using CLOSE.
6419 Calls `bfd_find_target', so TARGET is interpreted as by that
6422 Calls OPEN (which can call `bfd_zalloc' and `bfd_get_filename') to
6423 obtain the read-only stream backing the BFD. OPEN either succeeds
6424 returning the non-`NULL' STREAM, or fails returning `NULL' (setting
6427 Calls PREAD to request NBYTES of data from STREAM starting at OFFSET
6428 (e.g., via a call to `bfd_read'). PREAD either succeeds returning the
6429 number of bytes read (which can be less than NBYTES when end-of-file),
6430 or fails returning -1 (setting `bfd_error').
6432 Calls CLOSE when the BFD is later closed using `bfd_close'. CLOSE
6433 either succeeds returning 0, or fails returning -1 (setting
6436 If `bfd_openr_iovec' returns `NULL' then an error has occurred.
6437 Possible errors are `bfd_error_no_memory', `bfd_error_invalid_target'
6438 and `bfd_error_system_call'.
6440 2.14.1.6 `bfd_openw'
6441 ....................
6444 bfd *bfd_openw (const char *filename, const char *target);
6446 Create a BFD, associated with file FILENAME, using the file format
6447 TARGET, and return a pointer to it.
6449 Possible errors are `bfd_error_system_call', `bfd_error_no_memory',
6450 `bfd_error_invalid_target'.
6452 2.14.1.7 `bfd_close'
6453 ....................
6456 bfd_boolean bfd_close (bfd *abfd);
6458 Close a BFD. If the BFD was open for writing, then pending operations
6459 are completed and the file written out and closed. If the created file
6460 is executable, then `chmod' is called to mark it as such.
6462 All memory attached to the BFD is released.
6464 The file descriptor associated with the BFD is closed (even if it
6465 was passed in to BFD by `bfd_fdopenr').
6468 `TRUE' is returned if all is ok, otherwise `FALSE'.
6470 2.14.1.8 `bfd_close_all_done'
6471 .............................
6474 bfd_boolean bfd_close_all_done (bfd *);
6476 Close a BFD. Differs from `bfd_close' since it does not complete any
6477 pending operations. This routine would be used if the application had
6478 just used BFD for swapping and didn't want to use any of the writing
6481 If the created file is executable, then `chmod' is called to mark it
6484 All memory attached to the BFD is released.
6487 `TRUE' is returned if all is ok, otherwise `FALSE'.
6489 2.14.1.9 `bfd_create'
6490 .....................
6493 bfd *bfd_create (const char *filename, bfd *templ);
6495 Create a new BFD in the manner of `bfd_openw', but without opening a
6496 file. The new BFD takes the target from the target used by TEMPLATE.
6497 The format is always set to `bfd_object'.
6499 2.14.1.10 `bfd_make_writable'
6500 .............................
6503 bfd_boolean bfd_make_writable (bfd *abfd);
6505 Takes a BFD as created by `bfd_create' and converts it into one like as
6506 returned by `bfd_openw'. It does this by converting the BFD to
6507 BFD_IN_MEMORY. It's assumed that you will call `bfd_make_readable' on
6511 `TRUE' is returned if all is ok, otherwise `FALSE'.
6513 2.14.1.11 `bfd_make_readable'
6514 .............................
6517 bfd_boolean bfd_make_readable (bfd *abfd);
6519 Takes a BFD as created by `bfd_create' and `bfd_make_writable' and
6520 converts it into one like as returned by `bfd_openr'. It does this by
6521 writing the contents out to the memory buffer, then reversing the
6525 `TRUE' is returned if all is ok, otherwise `FALSE'.
6527 2.14.1.12 `bfd_alloc'
6528 .....................
6531 void *bfd_alloc (bfd *abfd, bfd_size_type wanted);
6533 Allocate a block of WANTED bytes of memory attached to `abfd' and
6534 return a pointer to it.
6536 2.14.1.13 `bfd_alloc2'
6537 ......................
6540 void *bfd_alloc2 (bfd *abfd, bfd_size_type nmemb, bfd_size_type size);
6542 Allocate a block of NMEMB elements of SIZE bytes each of memory
6543 attached to `abfd' and return a pointer to it.
6545 2.14.1.14 `bfd_zalloc'
6546 ......................
6549 void *bfd_zalloc (bfd *abfd, bfd_size_type wanted);
6551 Allocate a block of WANTED bytes of zeroed memory attached to `abfd'
6552 and return a pointer to it.
6554 2.14.1.15 `bfd_zalloc2'
6555 .......................
6558 void *bfd_zalloc2 (bfd *abfd, bfd_size_type nmemb, bfd_size_type size);
6560 Allocate a block of NMEMB elements of SIZE bytes each of zeroed memory
6561 attached to `abfd' and return a pointer to it.
6563 2.14.1.16 `bfd_calc_gnu_debuglink_crc32'
6564 ........................................
6567 unsigned long bfd_calc_gnu_debuglink_crc32
6568 (unsigned long crc, const unsigned char *buf, bfd_size_type len);
6570 Computes a CRC value as used in the .gnu_debuglink section. Advances
6571 the previously computed CRC value by computing and adding in the crc32
6572 for LEN bytes of BUF.
6575 Return the updated CRC32 value.
6577 2.14.1.17 `get_debug_link_info'
6578 ...............................
6581 char *get_debug_link_info (bfd *abfd, unsigned long *crc32_out);
6583 fetch the filename and CRC32 value for any separate debuginfo
6584 associated with ABFD. Return NULL if no such info found, otherwise
6585 return filename and update CRC32_OUT.
6587 2.14.1.18 `separate_debug_file_exists'
6588 ......................................
6591 bfd_boolean separate_debug_file_exists
6592 (char *name, unsigned long crc32);
6594 Checks to see if NAME is a file and if its contents match CRC32.
6596 2.14.1.19 `find_separate_debug_file'
6597 ....................................
6600 char *find_separate_debug_file (bfd *abfd);
6602 Searches ABFD for a reference to separate debugging information, scans
6603 various locations in the filesystem, including the file tree rooted at
6604 DEBUG_FILE_DIRECTORY, and returns a filename of such debugging
6605 information if the file is found and has matching CRC32. Returns NULL
6606 if no reference to debugging file exists, or file cannot be found.
6608 2.14.1.20 `bfd_follow_gnu_debuglink'
6609 ....................................
6612 char *bfd_follow_gnu_debuglink (bfd *abfd, const char *dir);
6614 Takes a BFD and searches it for a .gnu_debuglink section. If this
6615 section is found, it examines the section for the name and checksum of
6616 a '.debug' file containing auxiliary debugging information. It then
6617 searches the filesystem for this .debug file in some standard
6618 locations, including the directory tree rooted at DIR, and if found
6619 returns the full filename.
6621 If DIR is NULL, it will search a default path configured into libbfd
6622 at build time. [XXX this feature is not currently implemented].
6625 `NULL' on any errors or failure to locate the .debug file, otherwise a
6626 pointer to a heap-allocated string containing the filename. The caller
6627 is responsible for freeing this string.
6629 2.14.1.21 `bfd_create_gnu_debuglink_section'
6630 ............................................
6633 struct bfd_section *bfd_create_gnu_debuglink_section
6634 (bfd *abfd, const char *filename);
6636 Takes a BFD and adds a .gnu_debuglink section to it. The section is
6637 sized to be big enough to contain a link to the specified FILENAME.
6640 A pointer to the new section is returned if all is ok. Otherwise
6641 `NULL' is returned and bfd_error is set.
6643 2.14.1.22 `bfd_fill_in_gnu_debuglink_section'
6644 .............................................
6647 bfd_boolean bfd_fill_in_gnu_debuglink_section
6648 (bfd *abfd, struct bfd_section *sect, const char *filename);
6650 Takes a BFD and containing a .gnu_debuglink section SECT and fills in
6651 the contents of the section to contain a link to the specified
6652 FILENAME. The filename should be relative to the current directory.
6655 `TRUE' is returned if all is ok. Otherwise `FALSE' is returned and

6661 2.15 Implementation details
6662 ===========================
6664 2.15.1 Internal functions
6665 -------------------------
6668 These routines are used within BFD. They are not intended for export,
6669 but are documented here for completeness.
6671 2.15.1.1 `bfd_write_bigendian_4byte_int'
6672 ........................................
6675 bfd_boolean bfd_write_bigendian_4byte_int (bfd *, unsigned int);
6677 Write a 4 byte integer I to the output BFD ABFD, in big endian order
6678 regardless of what else is going on. This is useful in archives.
6680 2.15.1.2 `bfd_put_size'
6681 .......................
6683 2.15.1.3 `bfd_get_size'
6684 .......................
6687 These macros as used for reading and writing raw data in sections; each
6688 access (except for bytes) is vectored through the target format of the
6689 BFD and mangled accordingly. The mangling performs any necessary endian
6690 translations and removes alignment restrictions. Note that types
6691 accepted and returned by these macros are identical so they can be
6692 swapped around in macros--for example, `libaout.h' defines `GET_WORD'
6693 to either `bfd_get_32' or `bfd_get_64'.
6695 In the put routines, VAL must be a `bfd_vma'. If we are on a system
6696 without prototypes, the caller is responsible for making sure that is
6697 true, with a cast if necessary. We don't cast them in the macro
6698 definitions because that would prevent `lint' or `gcc -Wall' from
6699 detecting sins such as passing a pointer. To detect calling these with
6700 less than a `bfd_vma', use `gcc -Wconversion' on a host with 64 bit

6837 The file caching mechanism is embedded within BFD and allows the
6838 application to open as many BFDs as it wants without regard to the
6839 underlying operating system's file descriptor limit (often as low as 20
6840 open files). The module in `cache.c' maintains a least recently used
6841 list of `BFD_CACHE_MAX_OPEN' files, and exports the name
6842 `bfd_cache_lookup', which runs around and makes sure that the required
6843 BFD is open. If not, then it chooses a file to close, closes it and
6844 opens the one wanted, returning its file handle.

6898 2.17 Linker Functions
6899 =====================
6901 The linker uses three special entry points in the BFD target vector.
6902 It is not necessary to write special routines for these entry points
6903 when creating a new BFD back end, since generic versions are provided.
6904 However, writing them can speed up linking and make it use
6905 significantly less runtime memory.
6907 The first routine creates a hash table used by the other routines.
6908 The second routine adds the symbols from an object file to the hash
6909 table. The third routine takes all the object files and links them
6910 together to create the output file. These routines are designed so
6911 that the linker proper does not need to know anything about the symbols
6912 in the object files that it is linking. The linker merely arranges the
6913 sections as directed by the linker script and lets BFD handle the
6914 details of symbols and relocs.
6916 The second routine and third routines are passed a pointer to a
6917 `struct bfd_link_info' structure (defined in `bfdlink.h') which holds
6918 information relevant to the link, including the linker hash table
6919 (which was created by the first routine) and a set of callback
6920 functions to the linker proper.
6922 The generic linker routines are in `linker.c', and use the header
6923 file `genlink.h'. As of this writing, the only back ends which have
6924 implemented versions of these routines are a.out (in `aoutx.h') and
6925 ECOFF (in `ecoff.c'). The a.out routines are used as examples
6926 throughout this section.

6937 2.17.1 Creating a linker hash table
6938 -----------------------------------
6940 The linker routines must create a hash table, which must be derived
6941 from `struct bfd_link_hash_table' described in `bfdlink.c'. *Note Hash
6942 Tables::, for information on how to create a derived hash table. This
6943 entry point is called using the target vector of the linker output file.
6945 The `_bfd_link_hash_table_create' entry point must allocate and
6946 initialize an instance of the desired hash table. If the back end does
6947 not require any additional information to be stored with the entries in
6948 the hash table, the entry point may simply create a `struct
6949 bfd_link_hash_table'. Most likely, however, some additional
6950 information will be needed.
6952 For example, with each entry in the hash table the a.out linker
6953 keeps the index the symbol has in the final output file (this index
6954 number is used so that when doing a relocatable link the symbol index
6955 used in the output file can be quickly filled in when copying over a
6956 reloc). The a.out linker code defines the required structures and
6957 functions for a hash table derived from `struct bfd_link_hash_table'.
6958 The a.out linker hash table is created by the function
6959 `NAME(aout,link_hash_table_create)'; it simply allocates space for the
6960 hash table, initializes it, and returns a pointer to it.
6962 When writing the linker routines for a new back end, you will
6963 generally not know exactly which fields will be required until you have
6964 finished. You should simply create a new hash table which defines no
6965 additional fields, and then simply add fields as they become necessary.

6970 2.17.2 Adding symbols to the hash table
6971 ---------------------------------------
6973 The linker proper will call the `_bfd_link_add_symbols' entry point for
6974 each object file or archive which is to be linked (typically these are
6975 the files named on the command line, but some may also come from the
6976 linker script). The entry point is responsible for examining the file.
6977 For an object file, BFD must add any relevant symbol information to the
6978 hash table. For an archive, BFD must determine which elements of the
6979 archive should be used and adding them to the link.
6981 The a.out version of this entry point is
6982 `NAME(aout,link_add_symbols)'.

6991 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
6993 2.17.2.1 Differing file formats
6994 ...............................
6996 Normally all the files involved in a link will be of the same format,
6997 but it is also possible to link together different format object files,
6998 and the back end must support that. The `_bfd_link_add_symbols' entry
6999 point is called via the target vector of the file to be added. This
7000 has an important consequence: the function may not assume that the hash
7001 table is the type created by the corresponding
7002 `_bfd_link_hash_table_create' vector. All the `_bfd_link_add_symbols'
7003 function can assume about the hash table is that it is derived from
7004 `struct bfd_link_hash_table'.
7006 Sometimes the `_bfd_link_add_symbols' function must store some
7007 information in the hash table entry to be used by the `_bfd_final_link'
7008 function. In such a case the `creator' field of the hash table must be
7009 checked to make sure that the hash table was created by an object file
7012 The `_bfd_final_link' routine must be prepared to handle a hash
7013 entry without any extra information added by the
7014 `_bfd_link_add_symbols' function. A hash entry without extra
7015 information will also occur when the linker script directs the linker
7016 to create a symbol. Note that, regardless of how a hash table entry is
7017 added, all the fields will be initialized to some sort of null value by
7018 the hash table entry initialization function.
7020 See `ecoff_link_add_externals' for an example of how to check the
7021 `creator' field before saving information (in this case, the ECOFF
7022 external symbol debugging information) in a hash table entry.

7027 2.17.2.2 Adding symbols from an object file
7028 ...........................................
7030 When the `_bfd_link_add_symbols' routine is passed an object file, it
7031 must add all externally visible symbols in that object file to the hash
7032 table. The actual work of adding the symbol to the hash table is
7033 normally handled by the function `_bfd_generic_link_add_one_symbol'.
7034 The `_bfd_link_add_symbols' routine is responsible for reading all the
7035 symbols from the object file and passing the correct information to
7036 `_bfd_generic_link_add_one_symbol'.
7038 The `_bfd_link_add_symbols' routine should not use
7039 `bfd_canonicalize_symtab' to read the symbols. The point of providing
7040 this routine is to avoid the overhead of converting the symbols into
7041 generic `asymbol' structures.
7043 `_bfd_generic_link_add_one_symbol' handles the details of combining
7044 common symbols, warning about multiple definitions, and so forth. It
7045 takes arguments which describe the symbol to add, notably symbol flags,
7046 a section, and an offset. The symbol flags include such things as
7047 `BSF_WEAK' or `BSF_INDIRECT'. The section is a section in the object
7048 file, or something like `bfd_und_section_ptr' for an undefined symbol
7049 or `bfd_com_section_ptr' for a common symbol.
7051 If the `_bfd_final_link' routine is also going to need to read the
7052 symbol information, the `_bfd_link_add_symbols' routine should save it
7053 somewhere attached to the object file BFD. However, the information
7054 should only be saved if the `keep_memory' field of the `info' argument
7055 is TRUE, so that the `-no-keep-memory' linker switch is effective.
7057 The a.out function which adds symbols from an object file is
7058 `aout_link_add_object_symbols', and most of the interesting work is in
7059 `aout_link_add_symbols'. The latter saves pointers to the hash tables
7060 entries created by `_bfd_generic_link_add_one_symbol' indexed by symbol
7061 number, so that the `_bfd_final_link' routine does not have to call the
7062 hash table lookup routine to locate the entry.
7065 File: bfd.info, Node: Adding symbols from an archive, Prev: Adding symbols from an object file, Up: Adding Symbols to the Hash Table
7067 2.17.2.3 Adding symbols from an archive
7068 .......................................
7070 When the `_bfd_link_add_symbols' routine is passed an archive, it must
7071 look through the symbols defined by the archive and decide which
7072 elements of the archive should be included in the link. For each such
7073 element it must call the `add_archive_element' linker callback, and it
7074 must add the symbols from the object file to the linker hash table.
7076 In most cases the work of looking through the symbols in the archive
7077 should be done by the `_bfd_generic_link_add_archive_symbols' function.
7078 This function builds a hash table from the archive symbol table and
7079 looks through the list of undefined symbols to see which elements
7080 should be included. `_bfd_generic_link_add_archive_symbols' is passed
7081 a function to call to make the final decision about adding an archive
7082 element to the link and to do the actual work of adding the symbols to
7083 the linker hash table.
7085 The function passed to `_bfd_generic_link_add_archive_symbols' must
7086 read the symbols of the archive element and decide whether the archive
7087 element should be included in the link. If the element is to be
7088 included, the `add_archive_element' linker callback routine must be
7089 called with the element as an argument, and the elements symbols must
7090 be added to the linker hash table just as though the element had itself
7091 been passed to the `_bfd_link_add_symbols' function.
7093 When the a.out `_bfd_link_add_symbols' function receives an archive,
7094 it calls `_bfd_generic_link_add_archive_symbols' passing
7095 `aout_link_check_archive_element' as the function argument.
7096 `aout_link_check_archive_element' calls `aout_link_check_ar_symbols'.
7097 If the latter decides to add the element (an element is only added if
7098 it provides a real, non-common, definition for a previously undefined
7099 or common symbol) it calls the `add_archive_element' callback and then
7100 `aout_link_check_archive_element' calls `aout_link_add_symbols' to
7101 actually add the symbols to the linker hash table.
7103 The ECOFF back end is unusual in that it does not normally call
7104 `_bfd_generic_link_add_archive_symbols', because ECOFF archives already
7105 contain a hash table of symbols. The ECOFF back end searches the
7106 archive itself to avoid the overhead of creating a new hash table.

7111 2.17.3 Performing the final link
7112 --------------------------------
7114 When all the input files have been processed, the linker calls the
7115 `_bfd_final_link' entry point of the output BFD. This routine is
7116 responsible for producing the final output file, which has several
7117 aspects. It must relocate the contents of the input sections and copy
7118 the data into the output sections. It must build an output symbol
7119 table including any local symbols from the input files and the global
7120 symbols from the hash table. When producing relocatable output, it must
7121 modify the input relocs and write them into the output file. There may
7122 also be object format dependent work to be done.
7124 The linker will also call the `write_object_contents' entry point
7125 when the BFD is closed. The two entry points must work together in
7126 order to produce the correct output file.
7128 The details of how this works are inevitably dependent upon the
7129 specific object file format. The a.out `_bfd_final_link' routine is
7130 `NAME(aout,final_link)'.

7144 Before the linker calls the `_bfd_final_link' entry point, it sets up
7145 some data structures for the function to use.
7147 The `input_bfds' field of the `bfd_link_info' structure will point
7148 to a list of all the input files included in the link. These files are
7149 linked through the `link_next' field of the `bfd' structure.
7151 Each section in the output file will have a list of `link_order'
7152 structures attached to the `map_head.link_order' field (the
7153 `link_order' structure is defined in `bfdlink.h'). These structures
7154 describe how to create the contents of the output section in terms of
7155 the contents of various input sections, fill constants, and,
7156 eventually, other types of information. They also describe relocs that
7157 must be created by the BFD backend, but do not correspond to any input
7158 file; this is used to support -Ur, which builds constructors while
7159 generating a relocatable object file.

7164 2.17.3.2 Relocating the section contents
7165 ........................................
7167 The `_bfd_final_link' function should look through the `link_order'
7168 structures attached to each section of the output file. Each
7169 `link_order' structure should either be handled specially, or it should
7170 be passed to the function `_bfd_default_link_order' which will do the
7171 right thing (`_bfd_default_link_order' is defined in `linker.c').
7173 For efficiency, a `link_order' of type `bfd_indirect_link_order'
7174 whose associated section belongs to a BFD of the same format as the
7175 output BFD must be handled specially. This type of `link_order'
7176 describes part of an output section in terms of a section belonging to
7177 one of the input files. The `_bfd_final_link' function should read the
7178 contents of the section and any associated relocs, apply the relocs to
7179 the section contents, and write out the modified section contents. If
7180 performing a relocatable link, the relocs themselves must also be
7181 modified and written out.
7183 The functions `_bfd_relocate_contents' and
7184 `_bfd_final_link_relocate' provide some general support for performing
7185 the actual relocations, notably overflow checking. Their arguments
7186 include information about the symbol the relocation is against and a
7187 `reloc_howto_type' argument which describes the relocation to perform.
7188 These functions are defined in `reloc.c'.
7190 The a.out function which handles reading, relocating, and writing
7191 section contents is `aout_link_input_section'. The actual relocation
7192 is done in `aout_link_input_section_std' and
7193 `aout_link_input_section_ext'.

7204 `discard' fields of the `bfd_link_info' structure.
7206 The local symbols of the input files will not have been entered into
7207 the linker hash table. The `_bfd_final_link' routine must consider
7208 each input file and include the symbols in the output file. It may be
7209 convenient to do this when looking through the `link_order' structures,
7210 or it may be done by stepping through the `input_bfds' list.
7212 The `_bfd_final_link' routine must also traverse the global hash
7213 table to gather all the externally visible symbols. It is possible
7214 that most of the externally visible symbols may be written out when
7215 considering the symbols of each input file, but it is still necessary
7216 to traverse the hash table since the linker script may have defined
7217 some symbols that are not in any of the input files.
7219 The `strip' field of the `bfd_link_info' structure controls which
7220 symbols are written out. The possible values are listed in
7221 `bfdlink.h'. If the value is `strip_some', then the `keep_hash' field
7222 of the `bfd_link_info' structure is a hash table of symbols to keep;
7223 each symbol should be looked up in this hash table, and only symbols
7224 which are present should be included in the output file.
7226 If the `strip' field of the `bfd_link_info' structure permits local
7227 symbols to be written out, the `discard' field is used to further
7228 controls which local symbols are included in the output file. If the
7229 value is `discard_l', then all local symbols which begin with a certain
7230 prefix are discarded; this is controlled by the
7231 `bfd_is_local_label_name' entry point.
7233 The a.out backend handles symbols by calling
7234 `aout_link_write_symbols' on each input BFD and then traversing the
7235 global hash table with the function `aout_link_write_other_symbol'. It
7236 builds a string table while writing out the symbols, which is written
7237 to the output file at the end of `NAME(aout,final_link)'.

7268 BFD provides a simple set of hash table functions. Routines are
7269 provided to initialize a hash table, to free a hash table, to look up a
7270 string in a hash table and optionally create an entry for it, and to
7271 traverse a hash table. There is currently no routine to delete an
7272 string from a hash table.
7274 The basic hash table does not permit any data to be stored with a
7275 string. However, a hash table is designed to present a base class from
7276 which other types of hash tables may be derived. These derived types
7277 may store additional information with the string. Hash tables were
7278 implemented in this way, rather than simply providing a data pointer in
7279 a hash table entry, because they were designed for use by the linker
7280 back ends. The linker may create thousands of hash table entries, and
7281 the overhead of allocating private data and storing and following
7282 pointers becomes noticeable.
7284 The basic hash table code is in `hash.c'.

7296 2.18.1 Creating and freeing a hash table
7297 ----------------------------------------
7299 To create a hash table, create an instance of a `struct bfd_hash_table'
7300 (defined in `bfd.h') and call `bfd_hash_table_init' (if you know
7301 approximately how many entries you will need, the function
7302 `bfd_hash_table_init_n', which takes a SIZE argument, may be used).
7303 `bfd_hash_table_init' returns `FALSE' if some sort of error occurs.
7305 The function `bfd_hash_table_init' take as an argument a function to
7306 use to create new entries. For a basic hash table, use the function
7307 `bfd_hash_newfunc'. *Note Deriving a New Hash Table Type::, for why
7308 you would want to use a different value for this argument.
7310 `bfd_hash_table_init' will create an objalloc which will be used to
7311 allocate new entries. You may allocate memory on this objalloc using
7312 `bfd_hash_allocate'.
7314 Use `bfd_hash_table_free' to free up all the memory that has been
7315 allocated for a hash table. This will not free up the `struct
7316 bfd_hash_table' itself, which you must provide.
7318 Use `bfd_hash_set_default_size' to set the default size of hash

7324 2.18.2 Looking up or entering a string
7325 --------------------------------------
7327 The function `bfd_hash_lookup' is used both to look up a string in the
7328 hash table and to create a new entry.
7330 If the CREATE argument is `FALSE', `bfd_hash_lookup' will look up a
7331 string. If the string is found, it will returns a pointer to a `struct
7332 bfd_hash_entry'. If the string is not found in the table
7333 `bfd_hash_lookup' will return `NULL'. You should not modify any of the
7334 fields in the returns `struct bfd_hash_entry'.
7336 If the CREATE argument is `TRUE', the string will be entered into
7337 the hash table if it is not already there. Either way a pointer to a
7338 `struct bfd_hash_entry' will be returned, either to the existing
7339 structure or to a newly created one. In this case, a `NULL' return
7340 means that an error occurred.
7342 If the CREATE argument is `TRUE', and a new entry is created, the
7343 COPY argument is used to decide whether to copy the string onto the
7344 hash table objalloc or not. If COPY is passed as `FALSE', you must be
7345 careful not to deallocate or modify the string as long as the hash table

7351 2.18.3 Traversing a hash table
7352 ------------------------------
7354 The function `bfd_hash_traverse' may be used to traverse a hash table,
7355 calling a function on each element. The traversal is done in a random
7358 `bfd_hash_traverse' takes as arguments a function and a generic
7359 `void *' pointer. The function is called with a hash table entry (a
7360 `struct bfd_hash_entry *') and the generic pointer passed to
7361 `bfd_hash_traverse'. The function must return a `boolean' value, which
7362 indicates whether to continue traversing the hash table. If the
7363 function returns `FALSE', `bfd_hash_traverse' will stop the traversal
7364 and return immediately.

7369 2.18.4 Deriving a new hash table type
7370 -------------------------------------
7372 Many uses of hash tables want to store additional information which
7373 each entry in the hash table. Some also find it convenient to store
7374 additional information with the hash table itself. This may be done
7375 using a derived hash table.
7377 Since C is not an object oriented language, creating a derived hash
7378 table requires sticking together some boilerplate routines with a few
7379 differences specific to the type of hash table you want to create.
7381 An example of a derived hash table is the linker hash table. The
7382 structures for this are defined in `bfdlink.h'. The functions are in
7385 You may also derive a hash table from an already derived hash table.
7386 For example, the a.out linker backend code uses a hash table derived
7387 from the linker hash table.

7398 2.18.4.1 Define the derived structures
7399 ......................................
7401 You must define a structure for an entry in the hash table, and a
7402 structure for the hash table itself.
7404 The first field in the structure for an entry in the hash table must
7405 be of the type used for an entry in the hash table you are deriving
7406 from. If you are deriving from a basic hash table this is `struct
7407 bfd_hash_entry', which is defined in `bfd.h'. The first field in the
7408 structure for the hash table itself must be of the type of the hash
7409 table you are deriving from itself. If you are deriving from a basic
7410 hash table, this is `struct bfd_hash_table'.
7412 For example, the linker hash table defines `struct
7413 bfd_link_hash_entry' (in `bfdlink.h'). The first field, `root', is of
7414 type `struct bfd_hash_entry'. Similarly, the first field in `struct
7415 bfd_link_hash_table', `table', is of type `struct bfd_hash_table'.
7418 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
7420 2.18.4.2 Write the derived creation routine
7421 ...........................................
7423 You must write a routine which will create and initialize an entry in
7424 the hash table. This routine is passed as the function argument to
7425 `bfd_hash_table_init'.
7427 In order to permit other hash tables to be derived from the hash
7428 table you are creating, this routine must be written in a standard way.
7430 The first argument to the creation routine is a pointer to a hash
7431 table entry. This may be `NULL', in which case the routine should
7432 allocate the right amount of space. Otherwise the space has already
7433 been allocated by a hash table type derived from this one.
7435 After allocating space, the creation routine must call the creation
7436 routine of the hash table type it is derived from, passing in a pointer
7437 to the space it just allocated. This will initialize any fields used
7438 by the base hash table.
7440 Finally the creation routine must initialize any local fields for
7441 the new hash table type.
7443 Here is a boilerplate example of a creation routine. FUNCTION_NAME
7444 is the name of the routine. ENTRY_TYPE is the type of an entry in the
7445 hash table you are creating. BASE_NEWFUNC is the name of the creation
7446 routine of the hash table type your hash table is derived from.
7448 struct bfd_hash_entry *
7449 FUNCTION_NAME (struct bfd_hash_entry *entry,
7450 struct bfd_hash_table *table,
7453 struct ENTRY_TYPE *ret = (ENTRY_TYPE *) entry;
7455 /* Allocate the structure if it has not already been allocated by a
7459 ret = bfd_hash_allocate (table, sizeof (* ret));
7464 /* Call the allocation method of the base class. */
7465 ret = ((ENTRY_TYPE *)
7466 BASE_NEWFUNC ((struct bfd_hash_entry *) ret, table, string));
7468 /* Initialize the local fields here. */
7470 return (struct bfd_hash_entry *) ret;
7473 The creation routine for the linker hash table, which is in `linker.c',
7474 looks just like this example. FUNCTION_NAME is
7475 `_bfd_link_hash_newfunc'. ENTRY_TYPE is `struct bfd_link_hash_entry'.
7476 BASE_NEWFUNC is `bfd_hash_newfunc', the creation routine for a basic
7479 `_bfd_link_hash_newfunc' also initializes the local fields in a
7480 linker hash table entry: `type', `written' and `next'.

7485 2.18.4.3 Write other derived routines
7486 .....................................
7488 You will want to write other routines for your new hash table, as well.
7490 You will want an initialization routine which calls the
7491 initialization routine of the hash table you are deriving from and
7492 initializes any other local fields. For the linker hash table, this is
7493 `_bfd_link_hash_table_init' in `linker.c'.
7495 You will want a lookup routine which calls the lookup routine of the
7496 hash table you are deriving from and casts the result. The linker hash
7497 table uses `bfd_link_hash_lookup' in `linker.c' (this actually takes an
7498 additional argument which it uses to decide how to return the looked up
7501 You may want a traversal routine. This should just call the
7502 traversal routine of the hash table you are deriving from with
7503 appropriate casts. The linker hash table uses `bfd_link_hash_traverse'
7506 These routines may simply be defined as macros. For example, the
7507 a.out backend linker hash table, which is derived from the linker hash
7508 table, uses macros for the lookup and traversal routines. These are
7509 `aout_link_hash_lookup' and `aout_link_hash_traverse' in aoutx.h.

7528 3.1 What to Put Where
7529 =====================
7531 All of BFD lives in one directory.
7534 File: bfd.info, Node: aout, Next: coff, Prev: What to Put Where, Up: BFD back ends
7540 BFD supports a number of different flavours of a.out format, though the
7541 major differences are only the sizes of the structures on disk, and the
7542 shape of the relocation information.
7544 The support is split into a basic support file `aoutx.h' and other
7545 files which derive functions from the base. One derivation file is
7546 `aoutf1.h' (for a.out flavour 1), and adds to the basic a.out functions
7547 support for sun3, sun4, 386 and 29k a.out files, to create a target
7548 jump vector for a specific target.
7550 This information is further split out into more specific files for
7551 each machine, including `sunos.c' for sun3 and sun4, `newsos3.c' for
7552 the Sony NEWS, and `demo64.c' for a demonstration of a 64 bit a.out
7555 The base file `aoutx.h' defines general mechanisms for reading and
7556 writing records to and from disk and various other methods which BFD
7557 requires. It is included by `aout32.c' and `aout64.c' to form the names
7558 `aout_32_swap_exec_header_in', `aout_64_swap_exec_header_in', etc.
7560 As an example, this is what goes on to make the back end for a sun4,
7563 #define ARCH_SIZE 32
7566 Which exports names:
7569 aout_32_canonicalize_reloc
7570 aout_32_find_nearest_line
7572 aout_32_get_reloc_upper_bound
7577 #define TARGET_NAME "a.out-sunos-big"
7578 #define VECNAME sunos_big_vec
7581 requires all the names from `aout32.c', and produces the jump vector
7585 The file `host-aout.c' is a special case. It is for a large set of
7586 hosts that use "more or less standard" a.out files, and for which
7587 cross-debugging is not interesting. It uses the standard 32-bit a.out
7588 support routines, but determines the file offsets and addresses of the
7589 text, data, and BSS sections, the machine architecture and machine
7590 type, and the entry point address, in a host-dependent manner. Once
7591 these values have been determined, generic code is used to handle the
7594 When porting it to run on a new system, you must supply:
7598 HOST_MACHINE_ARCH (optional)
7599 HOST_MACHINE_MACHINE (optional)
7600 HOST_TEXT_START_ADDR
7603 in the file `../include/sys/h-XXX.h' (for your host). These values,
7604 plus the structures and macros defined in `a.out.h' on your host
7605 system, will produce a BFD target that will access ordinary a.out files
7606 on your host. To configure a new machine to use `host-aout.c', specify:
7608 TDEFAULTS = -DDEFAULT_VECTOR=host_aout_big_vec
7609 TDEPFILES= host-aout.o trad-core.o
7611 in the `config/XXX.mt' file, and modify `configure.in' to use the
7612 `XXX.mt' file (by setting "`bfd_target=XXX'") when your configuration
7619 The file `aoutx.h' provides for both the _standard_ and _extended_
7620 forms of a.out relocation records.
7622 The standard records contain only an address, a symbol index, and a
7623 type field. The extended records (used on 29ks and sparcs) also have a
7624 full integer for an addend.
7626 3.2.2 Internal entry points
7627 ---------------------------
7630 `aoutx.h' exports several routines for accessing the contents of an
7631 a.out file, which are gathered and exported in turn by various format
7632 specific files (eg sunos.c).
7634 3.2.2.1 `aout_SIZE_swap_exec_header_in'

7644 byte stream memory image into the internal exec header structure EXECP.

7647 ........................................
7650 void aout_SIZE_swap_exec_header_out
7652 struct internal_exec *execp,
7653 struct external_exec *raw_bytes);
7655 Swap the information in an internal exec header structure EXECP into
7656 the buffer RAW_BYTES ready for writing to disk.

7664 struct internal_exec *execp,
7665 const bfd_target *(*callback_to_real_object_p) (bfd *));
7667 Some a.out variant thinks that the file open in ABFD checking is an
7668 a.out file. Do some more checking, and set up for access if it really
7669 is. Call back to the calling environment's "finish up" function just
7670 before returning, to handle any last-minute setup.

7726 BFD supports a number of different flavours of coff format. The major
7727 differences between formats are the sizes and alignments of fields in
7728 structures on disk, and the occasional extra field.
7730 Coff in all its varieties is implemented with a few common files and
7731 a number of implementation specific files. For example, The 88k bcs
7732 coff format is implemented in the file `coff-m88k.c'. This file
7733 `#include's `coff/m88k.h' which defines the external structure of the
7734 coff format for the 88k, and `coff/internal.h' which defines the
7735 internal structure. `coff-m88k.c' also defines the relocations used by
7736 the 88k format *Note Relocations::.
7738 The Intel i960 processor version of coff is implemented in
7739 `coff-i960.c'. This file has the same structure as `coff-m88k.c',
7740 except that it includes `coff/i960.h' rather than `coff-m88k.h'.
7742 3.3.1 Porting to a new version of coff
7743 --------------------------------------
7745 The recommended method is to select from the existing implementations
7746 the version of coff which is most like the one you want to use. For
7747 example, we'll say that i386 coff is the one you select, and that your
7748 coff flavour is called foo. Copy `i386coff.c' to `foocoff.c', copy
7749 `../include/coff/i386.h' to `../include/coff/foo.h', and add the lines
7750 to `targets.c' and `Makefile.in' so that your new back end is used.
7751 Alter the shapes of the structures in `../include/coff/foo.h' so that
7752 they match what you need. You will probably also have to add `#ifdef's
7753 to the code in `coff/internal.h' and `coffcode.h' if your version of
7756 You can verify that your new BFD backend works quite simply by
7757 building `objdump' from the `binutils' directory, and making sure that
7758 its version of what's going on and your host system's idea (assuming it
7759 has the pretty standard coff dump utility, usually called `att-dump' or
7760 just `dump') are the same. Then clean up your code, and send what
7761 you've done to Cygnus. Then your stuff will be in the next release, and
7762 you won't have to keep integrating it.
7764 3.3.2 How the coff backend works
7765 --------------------------------
7770 The Coff backend is split into generic routines that are applicable to
7771 any Coff target and routines that are specific to a particular target.
7772 The target-specific routines are further split into ones which are
7773 basically the same for all Coff targets except that they use the
7774 external symbol format or use different values for certain constants.
7776 The generic routines are in `coffgen.c'. These routines work for
7777 any Coff target. They use some hooks into the target specific code;
7778 the hooks are in a `bfd_coff_backend_data' structure, one of which
7779 exists for each target.
7781 The essentially similar target-specific routines are in
7782 `coffcode.h'. This header file includes executable C code. The
7783 various Coff targets first include the appropriate Coff header file,
7784 make any special defines that are needed, and then include `coffcode.h'.
7786 Some of the Coff targets then also have additional routines in the
7787 target source file itself.
7789 For example, `coff-i960.c' includes `coff/internal.h' and
7790 `coff/i960.h'. It then defines a few constants, such as `I960', and
7791 includes `coffcode.h'. Since the i960 has complex relocation types,
7792 `coff-i960.c' also includes some code to manipulate the i960 relocs.
7793 This code is not in `coffcode.h' because it would not be used by any
7796 3.3.2.2 Bit twiddling
7797 .....................
7799 Each flavour of coff supported in BFD has its own header file
7800 describing the external layout of the structures. There is also an
7801 internal description of the coff layout, in `coff/internal.h'. A major
7802 function of the coff backend is swapping the bytes and twiddling the
7803 bits to translate the external form of the structures into the normal
7804 internal form. This is all performed in the `bfd_swap'_thing_direction
7805 routines. Some elements are different sizes between different versions
7806 of coff; it is the duty of the coff version specific include file to
7807 override the definitions of various packing routines in `coffcode.h'.
7808 E.g., the size of line number entry in coff is sometimes 16 bits, and
7809 sometimes 32 bits. `#define'ing `PUT_LNSZ_LNNO' and `GET_LNSZ_LNNO'
7810 will select the correct one. No doubt, some day someone will find a
7811 version of coff which has a varying field size not catered to at the
7812 moment. To port BFD, that person will have to add more `#defines'.
7813 Three of the bit twiddling routines are exported to `gdb';
7814 `coff_swap_aux_in', `coff_swap_sym_in' and `coff_swap_lineno_in'. `GDB'
7815 reads the symbol table on its own, but uses BFD to fix things up. More
7816 of the bit twiddlers are exported for `gas'; `coff_swap_aux_out',
7817 `coff_swap_sym_out', `coff_swap_lineno_out', `coff_swap_reloc_out',
7818 `coff_swap_filehdr_out', `coff_swap_aouthdr_out',
7819 `coff_swap_scnhdr_out'. `Gas' currently keeps track of all the symbol
7820 table and reloc drudgery itself, thereby saving the internal BFD
7821 overhead, but uses BFD to swap things on the way out, making cross
7822 ports much safer. Doing so also allows BFD (and thus the linker) to
7823 use the same header files as `gas', which makes one avenue to disaster
7826 3.3.2.3 Symbol reading
7827 ......................
7829 The simple canonical form for symbols used by BFD is not rich enough to
7830 keep all the information available in a coff symbol table. The back end
7831 gets around this problem by keeping the original symbol table around,
7832 "behind the scenes".
7834 When a symbol table is requested (through a call to
7835 `bfd_canonicalize_symtab'), a request gets through to
7836 `coff_get_normalized_symtab'. This reads the symbol table from the coff
7837 file and swaps all the structures inside into the internal form. It
7838 also fixes up all the pointers in the table (represented in the file by
7839 offsets from the first symbol in the table) into physical pointers to
7840 elements in the new internal table. This involves some work since the
7841 meanings of fields change depending upon context: a field that is a
7842 pointer to another structure in the symbol table at one moment may be
7843 the size in bytes of a structure at the next. Another pass is made
7844 over the table. All symbols which mark file names (`C_FILE' symbols)
7845 are modified so that the internal string points to the value in the
7846 auxent (the real filename) rather than the normal text associated with
7847 the symbol (`".file"').
7849 At this time the symbol names are moved around. Coff stores all
7850 symbols less than nine characters long physically within the symbol
7851 table; longer strings are kept at the end of the file in the string
7852 table. This pass moves all strings into memory and replaces them with
7853 pointers to the strings.
7855 The symbol table is massaged once again, this time to create the
7856 canonical table used by the BFD application. Each symbol is inspected
7857 in turn, and a decision made (using the `sclass' field) about the
7858 various flags to set in the `asymbol'. *Note Symbols::. The generated
7859 canonical table shares strings with the hidden internal symbol table.
7861 Any linenumbers are read from the coff file too, and attached to the
7862 symbols which own the functions the linenumbers belong to.
7864 3.3.2.4 Symbol writing
7865 ......................
7867 Writing a symbol to a coff file which didn't come from a coff file will
7868 lose any debugging information. The `asymbol' structure remembers the
7869 BFD from which the symbol was taken, and on output the back end makes
7870 sure that the same destination target as source target is present.
7872 When the symbols have come from a coff file then all the debugging
7873 information is preserved.
7875 Symbol tables are provided for writing to the back end in a vector
7876 of pointers to pointers. This allows applications like the linker to
7877 accumulate and output large symbol tables without having to do too much
7880 This function runs through the provided symbol table and patches
7881 each symbol marked as a file place holder (`C_FILE') to point to the
7882 next file place holder in the list. It also marks each `offset' field
7883 in the list with the offset from the first symbol of the current symbol.
7885 Another function of this procedure is to turn the canonical value
7886 form of BFD into the form used by coff. Internally, BFD expects symbol
7887 values to be offsets from a section base; so a symbol physically at
7888 0x120, but in a section starting at 0x100, would have the value 0x20.
7889 Coff expects symbols to contain their final value, so symbols have
7890 their values changed at this point to reflect their sum with their
7891 owning section. This transformation uses the `output_section' field of
7892 the `asymbol''s `asection' *Note Sections::.
7894 * `coff_mangle_symbols'
7895 This routine runs though the provided symbol table and uses the
7896 offsets generated by the previous pass and the pointers generated when
7897 the symbol table was read in to create the structured hierarchy
7898 required by coff. It changes each pointer to a symbol into the index
7899 into the symbol table of the asymbol.
7901 * `coff_write_symbols'
7902 This routine runs through the symbol table and patches up the
7903 symbols from their internal form into the coff way, calls the bit
7904 twiddlers, and writes out the table to the file.
7906 3.3.2.5 `coff_symbol_type'

8246 3.3.2.7 Writing relocations
8247 ...........................
8249 To write relocations, the back end steps though the canonical
8250 relocation table and create an `internal_reloc'. The symbol index to
8251 use is removed from the `offset' field in the symbol table supplied.
8252 The address comes directly from the sum of the section base address and
8253 the relocation offset; the type is dug directly from the howto field.
8254 Then the `internal_reloc' is swapped into the shape of an
8255 `external_reloc' and written out to disk.
8257 3.3.2.8 Reading linenumbers
8258 ...........................
8260 Creating the linenumber table is done by reading in the entire coff
8261 linenumber table, and creating another table for internal use.
8263 A coff linenumber table is structured so that each function is
8264 marked as having a line number of 0. Each line within the function is
8265 an offset from the first line in the function. The base of the line
8266 number information for the table is stored in the symbol associated
8269 Note: The PE format uses line number 0 for a flag indicating a new
8272 The information is copied from the external to the internal table,
8273 and each symbol which marks a function is marked by pointing its...
8275 How does this work ?
8277 3.3.2.9 Reading relocations
8278 ...........................
8280 Coff relocations are easily transformed into the internal BFD form
8283 Reading a coff relocation table is done in the following stages:
8285 * Read the entire coff relocation table into memory.
8287 * Process each relocation in turn; first swap it from the external
8288 to the internal form.
8290 * Turn the symbol referenced in the relocation's symbol index into a
8291 pointer into the canonical symbol table. This table is the same
8292 as the one returned by a call to `bfd_canonicalize_symtab'. The
8293 back end will call that routine and save the result if a
8294 canonicalization hasn't been done.
8296 * The reloc index is turned into a pointer to a howto structure, in
8297 a back end specific way. For instance, the 386 and 960 use the
8298 `r_type' to directly produce an index into a howto table vector;
8299 the 88k subtracts a number from the `r_type' field and creates an
8303 File: bfd.info, Node: elf, Next: mmo, Prev: coff, Up: BFD back ends
8308 BFD support for ELF formats is being worked on. Currently, the best
8309 supported back ends are for sparc and i386 (running svr4 or Solaris 2).
8311 Documentation of the internals of the support code still needs to be
8312 written. The code is changing quickly enough that we haven't bothered

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

8333 The mmo object format is used exclusively together with Professor
8334 Donald E. Knuth's educational 64-bit processor MMIX. The simulator
8335 `mmix' which is available at
8336 `http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz'
8337 understands this format. That package also includes a combined
8338 assembler and linker called `mmixal'. The mmo format has no advantages
8339 feature-wise compared to e.g. ELF. It is a simple non-relocatable
8340 object format with no support for archives or debugging information,
8341 except for symbol value information and line numbers (which is not yet
8342 implemented in BFD). See
8343 `http://www-cs-faculty.stanford.edu/~knuth/mmix.html' for more
8344 information about MMIX. The ELF format is used for intermediate object
8345 files in the BFD implementation.

8354 File: bfd.info, Node: File layout, Next: Symbol-table, Prev: mmo, Up: mmo
8359 The mmo file contents is not partitioned into named sections as with
8360 e.g. ELF. Memory areas is formed by specifying the location of the
8361 data that follows. Only the memory area `0x0000...00' to `0x01ff...ff'
8362 is executable, so it is used for code (and constants) and the area
8363 `0x2000...00' to `0x20ff...ff' is used for writable data. *Note mmo
8366 There is provision for specifying "special data" of 65536 different
8367 types. We use type 80 (decimal), arbitrarily chosen the same as the
8368 ELF `e_machine' number for MMIX, filling it with section information
8369 normally found in ELF objects. *Note mmo section mapping::.
8371 Contents is entered as 32-bit words, xor:ed over previous contents,
8372 always zero-initialized. A word that starts with the byte `0x98' forms
8373 a command called a `lopcode', where the next byte distinguished between
8374 the thirteen lopcodes. The two remaining bytes, called the `Y' and `Z'
8375 fields, or the `YZ' field (a 16-bit big-endian number), are used for
8376 various purposes different for each lopcode. As documented in
8377 `http://www-cs-faculty.stanford.edu/~knuth/mmixal-intro.ps.gz', the
8381 0x98000001. The next word is contents, regardless of whether it
8382 starts with 0x98 or not.
8385 0x9801YYZZ, where `Z' is 1 or 2. This is a location directive,
8386 setting the location for the next data to the next 32-bit word
8387 (for Z = 1) or 64-bit word (for Z = 2), plus Y * 2^56. Normally
8388 `Y' is 0 for the text segment and 2 for the data segment.
8391 0x9802YYZZ. Increase the current location by `YZ' bytes.
8394 0x9803YYZZ, where `Z' is 1 or 2. Store the current location as 64
8395 bits into the location pointed to by the next 32-bit (Z = 1) or
8396 64-bit (Z = 2) word, plus Y * 2^56.
8399 0x9804YYZZ. `YZ' is stored into the current location plus 2 - 4 *
8403 0x980500ZZ. `Z' is 16 or 24. A value `L' derived from the
8404 following 32-bit word are used in a manner similar to `YZ' in
8405 lop_fixr: it is xor:ed into the current location minus 4 * L. The
8406 first byte of the word is 0 or 1. If it is 1, then L = (LOWEST 24
8407 BITS OF WORD) - 2^Z, if 0, then L = (LOWEST 24 BITS OF WORD).
8410 0x9806YYZZ. `Y' is the file number, `Z' is count of 32-bit words.
8411 Set the file number to `Y' and the line counter to 0. The next Z
8412 * 4 bytes contain the file name, padded with zeros if the count is
8413 not a multiple of four. The same `Y' may occur multiple times,
8414 but `Z' must be 0 for all but the first occurrence.
8417 0x9807YYZZ. `YZ' is the line number. Together with lop_file, it
8418 forms the source location for the next 32-bit word. Note that for
8419 each non-lopcode 32-bit word, line numbers are assumed incremented
8423 0x9808YYZZ. `YZ' is the type number. Data until the next lopcode
8424 other than lop_quote forms special data of type `YZ'. *Note mmo
8427 Other types than 80, (or type 80 with a content that does not
8428 parse) is stored in sections named `.MMIX.spec_data.N' where N is
8429 the `YZ'-type. The flags for such a sections say not to allocate
8430 or load the data. The vma is 0. Contents of multiple occurrences
8431 of special data N is concatenated to the data of the previous
8432 lop_spec Ns. The location in data or code at which the lop_spec
8436 0x980901ZZ. The first lopcode in a file. The `Z' field forms the
8437 length of header information in 32-bit words, where the first word
8438 tells the time in seconds since `00:00:00 GMT Jan 1 1970'.
8441 0x980a00ZZ. Z > 32. This lopcode follows after all
8442 content-generating lopcodes in a program. The `Z' field denotes
8443 the value of `rG' at the beginning of the program. The following
8444 256 - Z big-endian 64-bit words are loaded into global registers
8448 0x980b0000. The next-to-last lopcode in a program. Must follow
8449 immediately after the lop_post lopcode and its data. After this
8450 lopcode follows all symbols in a compressed format (*note
8454 0x980cYYZZ. The last lopcode in a program. It must follow the
8455 lop_stab lopcode and its data. The `YZ' field contains the number
8456 of 32-bit words of symbol table information after the preceding
8459 Note that the lopcode "fixups"; `lop_fixr', `lop_fixrx' and
8460 `lop_fixo' are not generated by BFD, but are handled. They are
8461 generated by `mmixal'.
8463 This trivial one-label, one-instruction file:
8467 can be represented this way in mmo:
8469 0x98090101 - lop_pre, one 32-bit word with timestamp.
8471 0x98010002 - lop_loc, text segment, using a 64-bit address.
8472 Note that mmixal does not emit this for the file above.
8473 0x00000000 - Address, high 32 bits.
8474 0x00000000 - Address, low 32 bits.
8475 0x98060002 - lop_file, 2 32-bit words for file-name.
8477 0x2e730000 - ".s\0\0"
8478 0x98070001 - lop_line, line 1.
8479 0x00010203 - TRAP 1,2,3
8480 0x980a00ff - lop_post, setting $255 to 0.
8483 0x980b0000 - lop_stab for ":Main" = 0, serial 1.
8484 0x203a4040 *Note Symbol-table::.
8489 0x980c0005 - lop_end; symbol table contained five 32-bit words.

8494 3.5.2 Symbol table format
8495 -------------------------
8497 From mmixal.w (or really, the generated mmixal.tex) in
8498 `http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz'):
8499 "Symbols are stored and retrieved by means of a `ternary search trie',
8500 following ideas of Bentley and Sedgewick. (See ACM-SIAM Symp. on
8501 Discrete Algorithms `8' (1997), 360-369; R.Sedgewick, `Algorithms in C'
8502 (Reading, Mass. Addison-Wesley, 1998), `15.4'.) Each trie node stores
8503 a character, and there are branches to subtries for the cases where a
8504 given character is less than, equal to, or greater than the character
8505 in the trie. There also is a pointer to a symbol table entry if a
8506 symbol ends at the current node."
8508 So it's a tree encoded as a stream of bytes. The stream of bytes
8509 acts on a single virtual global symbol, adding and removing characters
8510 and signalling complete symbol points. Here, we read the stream and
8511 create symbols at the completion points.
8513 First, there's a control byte `m'. If any of the listed bits in `m'
8514 is nonzero, we execute what stands at the right, in the listed order:
8517 0x40 - Traverse left trie.
8518 (Read a new command byte and recurse.)
8521 0x2f - Read the next byte as a character and store it in the
8522 current character position; increment character position.
8523 Test the bits of `m':
8526 0x80 - The character is 16-bit (so read another byte,
8527 merge into current character.
8530 0xf - We have a complete symbol; parse the type, value
8531 and serial number and do what should be done
8532 with a symbol. The type and length information
8533 is in j = (m & 0xf).
8536 j == 0xf: A register variable. The following
8537 byte tells which register.
8538 j <= 8: An absolute symbol. Read j bytes as the
8539 big-endian number the symbol equals.
8540 A j = 2 with two zero bytes denotes an
8542 j > 8: As with j <= 8, but add (0x20 << 56)
8543 to the value in the following j - 8
8546 Then comes the serial number, as a variant of
8547 uleb128, but better named ubeb128:
8548 Read bytes and shift the previous value left 7
8549 (multiply by 128). Add in the new byte, repeat
8550 until a byte has bit 7 set. The serial number
8551 is the computed value minus 128.
8554 0x20 - Traverse middle trie. (Read a new command byte
8555 and recurse.) Decrement character position.
8558 0x10 - Traverse right trie. (Read a new command byte and
8561 Let's look again at the `lop_stab' for the trivial file (*note File
8564 0x980b0000 - lop_stab for ":Main" = 0, serial 1.
8571 This forms the trivial trie (note that the path between ":" and "M"
8583 016e "n" is the last character in a full symbol, and
8584 with a value represented in one byte.
8586 81 The serial number is 1.

8591 3.5.3 mmo section mapping
8592 -------------------------
8594 The implementation in BFD uses special data type 80 (decimal) to
8595 encapsulate and describe named sections, containing e.g. debug
8596 information. If needed, any datum in the encapsulation will be quoted
8597 using lop_quote. First comes a 32-bit word holding the number of
8598 32-bit words containing the zero-terminated zero-padded segment name.
8599 After the name there's a 32-bit word holding flags describing the
8600 section type. Then comes a 64-bit big-endian word with the section
8601 length (in bytes), then another with the section start address.
8602 Depending on the type of section, the contents might follow,
8603 zero-padded to 32-bit boundary. For a loadable section (such as data
8604 or code), the contents might follow at some later point, not
8605 necessarily immediately, as a lop_loc with the same start address as in
8606 the section description, followed by the contents. This in effect
8607 forms a descriptor that must be emitted before the actual contents.
8608 Sections described this way must not overlap.
8610 For areas that don't have such descriptors, synthetic sections are
8611 formed by BFD. Consecutive contents in the two memory areas
8612 `0x0000...00' to `0x01ff...ff' and `0x2000...00' to `0x20ff...ff' are
8613 entered in sections named `.text' and `.data' respectively. If an area
8614 is not otherwise described, but would together with a neighboring lower
8615 area be less than `0x40000000' bytes long, it is joined with the lower
8616 area and the gap is zero-filled. For other cases, a new section is
8617 formed, named `.MMIX.sec.N'. Here, N is a number, a running count
8618 through the mmo file, starting at 0.
8620 A loadable section specified as:
8622 .section secname,"ax"
8623 TETRA 1,2,3,4,-1,-2009
8626 and linked to address `0x4', is represented by the sequence:
8628 0x98080050 - lop_spec 80
8629 0x00000002 - two 32-bit words for the section name
8631 0x616d6500 - "ame\0"
8632 0x00000033 - flags CODE, READONLY, LOAD, ALLOC
8633 0x00000000 - high 32 bits of section length
8634 0x0000001c - section length is 28 bytes; 6 * 4 + 1 + alignment to 32 bits
8635 0x00000000 - high 32 bits of section address
8636 0x00000004 - section address is 4
8637 0x98010002 - 64 bits with address of following data
8638 0x00000000 - high 32 bits of address
8639 0x00000004 - low 32 bits: data starts at address 4
8646 0x50000000 - 80 as a byte, padded with zeros.
8648 Note that the lop_spec wrapping does not include the section
8649 contents. Compare this to a non-loaded section specified as:
8655 This, when linked to address `0x200000000000001c', is represented by:
8657 0x98080050 - lop_spec 80
8658 0x00000002 - two 32-bit words for the section name
8661 0x00000010 - flag READONLY
8662 0x00000000 - high 32 bits of section length
8663 0x0000000c - section length is 12 bytes; 2 * 4 + 2 + alignment to 32 bits
8664 0x20000000 - high 32 bits of address
8665 0x0000001c - low 32 bits of address 0x200000000000001c
8668 0x26280000 - 38, 40 as bytes, padded with zeros
8670 For the latter example, the section contents must not be loaded in
8671 memory, and is therefore specified as part of the special data. The
8672 address is usually unimportant but might provide information for e.g.
8673 the DWARF 2 debugging format.

8686 Everyone is permitted to copy and distribute verbatim copies
8687 of this license document, but changing it is not allowed.
8692 The purpose of this License is to make a manual, textbook, or other
8693 written document "free" in the sense of freedom: to assure everyone
8694 the effective freedom to copy and redistribute it, with or without
8695 modifying it, either commercially or noncommercially. Secondarily,
8696 this License preserves for the author and publisher a way to get
8697 credit for their work, while not being considered responsible for
8698 modifications made by others.
8700 This License is a kind of "copyleft", which means that derivative
8701 works of the document must themselves be free in the same sense.
8702 It complements the GNU General Public License, which is a copyleft
8703 license designed for free software.
8705 We have designed this License in order to use it for manuals for
8706 free software, because free software needs free documentation: a
8707 free program should come with manuals providing the same freedoms
8708 that the software does. But this License is not limited to
8709 software manuals; it can be used for any textual work, regardless
8710 of subject matter or whether it is published as a printed book.
8711 We recommend this License principally for works whose purpose is
8712 instruction or reference.
8715 1. APPLICABILITY AND DEFINITIONS
8717 This License applies to any manual or other work that contains a
8718 notice placed by the copyright holder saying it can be distributed
8719 under the terms of this License. The "Document", below, refers to
8720 any such manual or work. Any member of the public is a licensee,
8721 and is addressed as "you."
8723 A "Modified Version" of the Document means any work containing the
8724 Document or a portion of it, either copied verbatim, or with
8725 modifications and/or translated into another language.
8727 A "Secondary Section" is a named appendix or a front-matter
8728 section of the Document that deals exclusively with the
8729 relationship of the publishers or authors of the Document to the
8730 Document's overall subject (or to related matters) and contains
8731 nothing that could fall directly within that overall subject.
8732 (For example, if the Document is in part a textbook of
8733 mathematics, a Secondary Section may not explain any mathematics.)
8734 The relationship could be a matter of historical connection with
8735 the subject or with related matters, or of legal, commercial,
8736 philosophical, ethical or political position regarding them.
8738 The "Invariant Sections" are certain Secondary Sections whose
8739 titles are designated, as being those of Invariant Sections, in
8740 the notice that says that the Document is released under this
8743 The "Cover Texts" are certain short passages of text that are
8744 listed, as Front-Cover Texts or Back-Cover Texts, in the notice
8745 that says that the Document is released under this License.
8747 A "Transparent" copy of the Document means a machine-readable copy,
8748 represented in a format whose specification is available to the
8749 general public, whose contents can be viewed and edited directly
8750 and straightforwardly with generic text editors or (for images
8751 composed of pixels) generic paint programs or (for drawings) some
8752 widely available drawing editor, and that is suitable for input to
8753 text formatters or for automatic translation to a variety of
8754 formats suitable for input to text formatters. A copy made in an
8755 otherwise Transparent file format whose markup has been designed
8756 to thwart or discourage subsequent modification by readers is not
8757 Transparent. A copy that is not "Transparent" is called "Opaque."
8759 Examples of suitable formats for Transparent copies include plain
8760 ASCII without markup, Texinfo input format, LaTeX input format,
8761 SGML or XML using a publicly available DTD, and
8762 standard-conforming simple HTML designed for human modification.
8763 Opaque formats include PostScript, PDF, proprietary formats that
8764 can be read and edited only by proprietary word processors, SGML
8765 or XML for which the DTD and/or processing tools are not generally
8766 available, and the machine-generated HTML produced by some word
8767 processors for output purposes only.
8769 The "Title Page" means, for a printed book, the title page itself,
8770 plus such following pages as are needed to hold, legibly, the
8771 material this License requires to appear in the title page. For
8772 works in formats which do not have any title page as such, "Title
8773 Page" means the text near the most prominent appearance of the
8774 work's title, preceding the beginning of the body of the text.
8778 You may copy and distribute the Document in any medium, either
8779 commercially or noncommercially, provided that this License, the
8780 copyright notices, and the license notice saying this License
8781 applies to the Document are reproduced in all copies, and that you
8782 add no other conditions whatsoever to those of this License. You
8783 may not use technical measures to obstruct or control the reading
8784 or further copying of the copies you make or distribute. However,
8785 you may accept compensation in exchange for copies. If you
8786 distribute a large enough number of copies you must also follow
8787 the conditions in section 3.
8789 You may also lend copies, under the same conditions stated above,
8790 and you may publicly display copies.
8792 3. COPYING IN QUANTITY
8794 If you publish printed copies of the Document numbering more than
8795 100, and the Document's license notice requires Cover Texts, you
8796 must enclose the copies in covers that carry, clearly and legibly,
8797 all these Cover Texts: Front-Cover Texts on the front cover, and
8798 Back-Cover Texts on the back cover. Both covers must also clearly
8799 and legibly identify you as the publisher of these copies. The
8800 front cover must present the full title with all words of the
8801 title equally prominent and visible. You may add other material
8802 on the covers in addition. Copying with changes limited to the
8803 covers, as long as they preserve the title of the Document and
8804 satisfy these conditions, can be treated as verbatim copying in
8807 If the required texts for either cover are too voluminous to fit
8808 legibly, you should put the first ones listed (as many as fit
8809 reasonably) on the actual cover, and continue the rest onto
8812 If you publish or distribute Opaque copies of the Document
8813 numbering more than 100, you must either include a
8814 machine-readable Transparent copy along with each Opaque copy, or
8815 state in or with each Opaque copy a publicly-accessible
8816 computer-network location containing a complete Transparent copy
8817 of the Document, free of added material, which the general
8818 network-using public has access to download anonymously at no
8819 charge using public-standard network protocols. If you use the
8820 latter option, you must take reasonably prudent steps, when you
8821 begin distribution of Opaque copies in quantity, to ensure that
8822 this Transparent copy will remain thus accessible at the stated
8823 location until at least one year after the last time you
8824 distribute an Opaque copy (directly or through your agents or
8825 retailers) of that edition to the public.
8827 It is requested, but not required, that you contact the authors of
8828 the Document well before redistributing any large number of
8829 copies, to give them a chance to provide you with an updated
8830 version of the Document.
8834 You may copy and distribute a Modified Version of the Document
8835 under the conditions of sections 2 and 3 above, provided that you
8836 release the Modified Version under precisely this License, with
8837 the Modified Version filling the role of the Document, thus
8838 licensing distribution and modification of the Modified Version to
8839 whoever possesses a copy of it. In addition, you must do these
8840 things in the Modified Version:
8842 A. Use in the Title Page (and on the covers, if any) a title
8843 distinct from that of the Document, and from those of previous
8844 versions (which should, if there were any, be listed in the
8845 History section of the Document). You may use the same title
8846 as a previous version if the original publisher of that version
8848 B. List on the Title Page, as authors, one or more persons or
8849 entities responsible for authorship of the modifications in the
8850 Modified Version, together with at least five of the principal
8851 authors of the Document (all of its principal authors, if it
8852 has less than five).
8853 C. State on the Title page the name of the publisher of the
8854 Modified Version, as the publisher.
8855 D. Preserve all the copyright notices of the Document.
8856 E. Add an appropriate copyright notice for your modifications
8857 adjacent to the other copyright notices.
8858 F. Include, immediately after the copyright notices, a license
8859 notice giving the public permission to use the Modified Version
8860 under the terms of this License, in the form shown in the
8862 G. Preserve in that license notice the full lists of Invariant
8863 Sections and required Cover Texts given in the Document's
8865 H. Include an unaltered copy of this License.
8866 I. Preserve the section entitled "History", and its title, and add
8867 to it an item stating at least the title, year, new authors, and
8868 publisher of the Modified Version as given on the Title Page. If
8869 there is no section entitled "History" in the Document, create
8870 one stating the title, year, authors, and publisher of the
8871 Document as given on its Title Page, then add an item
8872 describing the Modified Version as stated in the previous
8874 J. Preserve the network location, if any, given in the Document for
8875 public access to a Transparent copy of the Document, and likewise
8876 the network locations given in the Document for previous versions
8877 it was based on. These may be placed in the "History" section.
8878 You may omit a network location for a work that was published at
8879 least four years before the Document itself, or if the original
8880 publisher of the version it refers to gives permission.
8881 K. In any section entitled "Acknowledgements" or "Dedications",
8882 preserve the section's title, and preserve in the section all the
8883 substance and tone of each of the contributor acknowledgements
8884 and/or dedications given therein.
8885 L. Preserve all the Invariant Sections of the Document,
8886 unaltered in their text and in their titles. Section numbers
8887 or the equivalent are not considered part of the section titles.
8888 M. Delete any section entitled "Endorsements." Such a section
8889 may not be included in the Modified Version.
8890 N. Do not retitle any existing section as "Endorsements" or to
8891 conflict in title with any Invariant Section.
8893 If the Modified Version includes new front-matter sections or
8894 appendices that qualify as Secondary Sections and contain no
8895 material copied from the Document, you may at your option
8896 designate some or all of these sections as invariant. To do this,
8897 add their titles to the list of Invariant Sections in the Modified
8898 Version's license notice. These titles must be distinct from any
8899 other section titles.
8901 You may add a section entitled "Endorsements", provided it contains
8902 nothing but endorsements of your Modified Version by various
8903 parties-for example, statements of peer review or that the text has
8904 been approved by an organization as the authoritative definition
8907 You may add a passage of up to five words as a Front-Cover Text,
8908 and a passage of up to 25 words as a Back-Cover Text, to the end
8909 of the list of Cover Texts in the Modified Version. Only one
8910 passage of Front-Cover Text and one of Back-Cover Text may be
8911 added by (or through arrangements made by) any one entity. If the
8912 Document already includes a cover text for the same cover,
8913 previously added by you or by arrangement made by the same entity
8914 you are acting on behalf of, you may not add another; but you may
8915 replace the old one, on explicit permission from the previous
8916 publisher that added the old one.
8918 The author(s) and publisher(s) of the Document do not by this
8919 License give permission to use their names for publicity for or to
8920 assert or imply endorsement of any Modified Version.
8922 5. COMBINING DOCUMENTS
8924 You may combine the Document with other documents released under
8925 this License, under the terms defined in section 4 above for
8926 modified versions, provided that you include in the combination
8927 all of the Invariant Sections of all of the original documents,
8928 unmodified, and list them all as Invariant Sections of your
8929 combined work in its license notice.
8931 The combined work need only contain one copy of this License, and
8932 multiple identical Invariant Sections may be replaced with a single
8933 copy. If there are multiple Invariant Sections with the same name
8934 but different contents, make the title of each such section unique
8935 by adding at the end of it, in parentheses, the name of the
8936 original author or publisher of that section if known, or else a
8937 unique number. Make the same adjustment to the section titles in
8938 the list of Invariant Sections in the license notice of the
8941 In the combination, you must combine any sections entitled
8942 "History" in the various original documents, forming one section
8943 entitled "History"; likewise combine any sections entitled
8944 "Acknowledgements", and any sections entitled "Dedications." You
8945 must delete all sections entitled "Endorsements."
8947 6. COLLECTIONS OF DOCUMENTS
8949 You may make a collection consisting of the Document and other
8950 documents released under this License, and replace the individual
8951 copies of this License in the various documents with a single copy
8952 that is included in the collection, provided that you follow the
8953 rules of this License for verbatim copying of each of the
8954 documents in all other respects.
8956 You may extract a single document from such a collection, and
8957 distribute it individually under this License, provided you insert
8958 a copy of this License into the extracted document, and follow
8959 this License in all other respects regarding verbatim copying of
8962 7. AGGREGATION WITH INDEPENDENT WORKS
8964 A compilation of the Document or its derivatives with other
8965 separate and independent documents or works, in or on a volume of
8966 a storage or distribution medium, does not as a whole count as a
8967 Modified Version of the Document, provided no compilation
8968 copyright is claimed for the compilation. Such a compilation is
8969 called an "aggregate", and this License does not apply to the
8970 other self-contained works thus compiled with the Document, on
8971 account of their being thus compiled, if they are not themselves
8972 derivative works of the Document.
8974 If the Cover Text requirement of section 3 is applicable to these
8975 copies of the Document, then if the Document is less than one
8976 quarter of the entire aggregate, the Document's Cover Texts may be
8977 placed on covers that surround only the Document within the
8978 aggregate. Otherwise they must appear on covers around the whole
8983 Translation is considered a kind of modification, so you may
8984 distribute translations of the Document under the terms of section
8985 4. Replacing Invariant Sections with translations requires special
8986 permission from their copyright holders, but you may include
8987 translations of some or all Invariant Sections in addition to the
8988 original versions of these Invariant Sections. You may include a
8989 translation of this License provided that you also include the
8990 original English version of this License. In case of a
8991 disagreement between the translation and the original English
8992 version of this License, the original English version will prevail.
8996 You may not copy, modify, sublicense, or distribute the Document
8997 except as expressly provided for under this License. Any other
8998 attempt to copy, modify, sublicense or distribute the Document is
8999 void, and will automatically terminate your rights under this
9000 License. However, parties who have received copies, or rights,
9001 from you under this License will not have their licenses
9002 terminated so long as such parties remain in full compliance.
9004 10. FUTURE REVISIONS OF THIS LICENSE
9006 The Free Software Foundation may publish new, revised versions of
9007 the GNU Free Documentation License from time to time. Such new
9008 versions will be similar in spirit to the present version, but may
9009 differ in detail to address new problems or concerns. See
9010 http://www.gnu.org/copyleft/.
9012 Each version of the License is given a distinguishing version
9013 number. If the Document specifies that a particular numbered
9014 version of this License "or any later version" applies to it, you
9015 have the option of following the terms and conditions either of
9016 that specified version or of any later version that has been
9017 published (not as a draft) by the Free Software Foundation. If
9018 the Document does not specify a version number of this License,
9019 you may choose any version ever published (not as a draft) by the
9020 Free Software Foundation.
9023 ADDENDUM: How to use this License for your documents
9024 ====================================================
9026 To use this License in a document you have written, include a copy of
9027 the License in the document and put the following copyright and license
9028 notices just after the title page:
9030 Copyright (C) YEAR YOUR NAME.
9031 Permission is granted to copy, distribute and/or modify this document
9032 under the terms of the GNU Free Documentation License, Version 1.1
9033 or any later version published by the Free Software Foundation;
9034 with the Invariant Sections being LIST THEIR TITLES, with the
9035 Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
9036 A copy of the license is included in the section entitled "GNU
9037 Free Documentation License."
9039 If you have no Invariant Sections, write "with no Invariant Sections"
9040 instead of saying which ones are invariant. If you have no Front-Cover
9041 Texts, write "no Front-Cover Texts" instead of "Front-Cover Texts being
9042 LIST"; likewise for Back-Cover Texts.
9044 If your document contains nontrivial examples of program code, we
9045 recommend releasing these examples in parallel under your choice of
9046 free software license, such as the GNU General Public License, to
9047 permit their use in free software.
