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

63 File: bfd.info, Node: History, Next: How It Works, Prev: Overview, Up: Overview
68 One spur behind BFD was the desire, on the part of the GNU 960 team at
69 Intel Oregon, for interoperability of applications on their COFF and
70 b.out file formats. Cygnus was providing GNU support for the team, and
71 was contracted to provide the required functionality.
73 The name came from a conversation David Wallace was having with
74 Richard Stallman about the library: RMS said that it would be quite
75 hard--David said "BFD". Stallman was right, but the name stuck.
77 At the same time, Ready Systems wanted much the same thing, but for
78 different object file formats: IEEE-695, Oasys, Srecords, a.out and 68k
81 BFD was first implemented by members of Cygnus Support; Steve
82 Chamberlain (`sac@cygnus.com'), John Gilmore (`gnu@cygnus.com'), K.
83 Richard Pixley (`rich@cygnus.com') and David Henkel-Wallace
87 File: bfd.info, Node: How It Works, Next: What BFD Version 2 Can Do, Prev: History, Up: Overview
92 To use the library, include `bfd.h' and link with `libbfd.a'.
94 BFD provides a common interface to the parts of an object file for a
97 When an application sucessfully opens a target file (object,
98 archive, or whatever), a pointer to an internal structure is returned.
99 This pointer points to a structure called `bfd', described in `bfd.h'.
100 Our convention is to call this pointer a BFD, and instances of it
101 within code `abfd'. All operations on the target object file are
102 applied as methods to the BFD. The mapping is defined within `bfd.h'
103 in a set of macros, all beginning with `bfd_' to reduce namespace
106 For example, this sequence does what you would probably expect:
107 return the number of sections in an object file attached to a BFD
112 unsigned int number_of_sections (abfd)
115 return bfd_count_sections (abfd);
118 The abstraction used within BFD is that an object file has:
122 * a number of sections containing raw data (*note Sections::),
124 * a set of relocations (*note Relocations::), and
126 * some symbol information (*note Symbols::).
127 Also, BFDs opened for archives have the additional attribute of an
128 index and contain subordinate BFDs. This approach is fine for a.out and
129 coff, but loses efficiency when applied to formats such as S-records and
133 File: bfd.info, Node: What BFD Version 2 Can Do, Prev: How It Works, Up: Overview
135 1.3 What BFD Version 2 Can Do
136 =============================
138 When an object file is opened, BFD subroutines automatically determine
139 the format of the input object file. They then build a descriptor in
140 memory with pointers to routines that will be used to access elements of
141 the object file's data structures.
143 As different information from the object files is required, BFD
144 reads from different sections of the file and processes them. For
145 example, a very common operation for the linker is processing symbol
146 tables. Each BFD back end provides a routine for converting between
147 the object file's representation of symbols and an internal canonical
148 format. When the linker asks for the symbol table of an object file, it
149 calls through a memory pointer to the routine from the relevant BFD
150 back end which reads and converts the table into a canonical form. The
151 linker then operates upon the canonical form. When the link is finished
152 and the linker writes the output file's symbol table, another BFD back
153 end routine is called to take the newly created symbol table and
154 convert it into the chosen output format.

159 * Canonical format:: The BFD canonical object-file format
162 File: bfd.info, Node: BFD information loss, Next: Canonical format, Up: What BFD Version 2 Can Do
164 1.3.1 Information Loss
165 ----------------------
167 _Information can be lost during output._ The output formats supported
168 by BFD do not provide identical facilities, and information which can
169 be described in one form has nowhere to go in another format. One
170 example of this is alignment information in `b.out'. There is nowhere
171 in an `a.out' format file to store alignment information on the
172 contained data, so when a file is linked from `b.out' and an `a.out'
173 image is produced, alignment information will not propagate to the
174 output file. (The linker will still use the alignment information
175 internally, so the link is performed correctly).
177 Another example is COFF section names. COFF files may contain an
178 unlimited number of sections, each one with a textual section name. If
179 the target of the link is a format which does not have many sections
180 (e.g., `a.out') or has sections without names (e.g., the Oasys format),
181 the link cannot be done simply. You can circumvent this problem by
182 describing the desired input-to-output section mapping with the linker
185 _Information can be lost during canonicalization._ The BFD internal
186 canonical form of the external formats is not exhaustive; there are
187 structures in input formats for which there is no direct representation
188 internally. This means that the BFD back ends cannot maintain all
189 possible data richness through the transformation between external to
190 internal and back to external formats.
192 This limitation is only a problem when an application reads one
193 format and writes another. Each BFD back end is responsible for
194 maintaining as much data as possible, and the internal BFD canonical
195 form has structures which are opaque to the BFD core, and exported only
196 to the back ends. When a file is read in one format, the canonical form
197 is generated for BFD and the application. At the same time, the back
198 end saves away any information which may otherwise be lost. If the data
199 is then written back in the same format, the back end routine will be
200 able to use the canonical form provided by the BFD core as well as the
201 information it prepared earlier. Since there is a great deal of
202 commonality between back ends, there is no information lost when
203 linking or copying big endian COFF to little endian COFF, or `a.out' to
204 `b.out'. When a mixture of formats is linked, the information is only
205 lost from the files whose format differs from the destination.
208 File: bfd.info, Node: Canonical format, Prev: BFD information loss, Up: What BFD Version 2 Can Do
210 1.3.2 The BFD canonical object-file format
211 ------------------------------------------
213 The greatest potential for loss of information occurs when there is the
214 least overlap between the information provided by the source format,
215 that stored by the canonical format, and that needed by the destination
216 format. A brief description of the canonical form may help you
217 understand which kinds of data you can count on preserving across
221 Information stored on a per-file basis includes target machine
222 architecture, particular implementation format type, a demand
223 pageable bit, and a write protected bit. Information like Unix
224 magic numbers is not stored here--only the magic numbers' meaning,
225 so a `ZMAGIC' file would have both the demand pageable bit and the
226 write protected text bit set. The byte order of the target is
227 stored on a per-file basis, so that big- and little-endian object
228 files may be used with one another.
231 Each section in the input file contains the name of the section,
232 the section's original address in the object file, size and
233 alignment information, various flags, and pointers into other BFD
237 Each symbol contains a pointer to the information for the object
238 file which originally defined it, its name, its value, and various
239 flag bits. When a BFD back end reads in a symbol table, it
240 relocates all symbols to make them relative to the base of the
241 section where they were defined. Doing this ensures that each
242 symbol points to its containing section. Each symbol also has a
243 varying amount of hidden private data for the BFD back end. Since
244 the symbol points to the original file, the private data format
245 for that symbol is accessible. `ld' can operate on a collection
246 of symbols of wildly different formats without problems.
248 Normal global and simple local symbols are maintained on output,
249 so an output file (no matter its format) will retain symbols
250 pointing to functions and to global, static, and common variables.
251 Some symbol information is not worth retaining; in `a.out', type
252 information is stored in the symbol table as long symbol names.
253 This information would be useless to most COFF debuggers; the
254 linker has command line switches to allow users to throw it away.
256 There is one word of type information within the symbol, so if the
257 format supports symbol type information within symbols (for
258 example, COFF, IEEE, Oasys) and the type is simple enough to fit
259 within one word (nearly everything but aggregates), the
260 information will be preserved.
263 Each canonical BFD relocation record contains a pointer to the
264 symbol to relocate to, the offset of the data to relocate, the
265 section the data is in, and a pointer to a relocation type
266 descriptor. Relocation is performed by passing messages through
267 the relocation type descriptor and the symbol pointer. Therefore,
268 relocations can be performed on output data using a relocation
269 method that is only available in one of the input formats. For
270 instance, Oasys provides a byte relocation format. A relocation
271 record requesting this relocation type would point indirectly to a
272 routine to perform this, so the relocation may be performed on a
273 byte being written to a 68k COFF file, even though 68k COFF has no
274 such relocation type.
277 Object formats can contain, for debugging purposes, some form of
278 mapping between symbols, source line numbers, and addresses in the
279 output file. These addresses have to be relocated along with the
280 symbol information. Each symbol with an associated list of line
281 number records points to the first record of the list. The head
282 of a line number list consists of a pointer to the symbol, which
283 allows finding out the address of the function whose line number
284 is being described. The rest of the list is made up of pairs:
285 offsets into the section and line numbers. Any format which can
286 simply derive this information can pass it successfully between
287 formats (COFF, IEEE and Oasys).

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

530 Set the BFD error condition to be ERROR_TAG.
536 const char *bfd_errmsg (bfd_error_type error_tag);
538 Return a string describing the error ERROR_TAG, or the system error if
539 ERROR_TAG is `bfd_error_system_call'.
545 void bfd_perror (const char *message);
547 Print to the standard error stream a string describing the last BFD
548 error that occurred, or the last system error if the last BFD error was
549 a system call failure. If MESSAGE is non-NULL and non-empty, the error

574 ....................................
577 void bfd_set_error_program_name (const char *);
579 Set the program name to use when printing a BFD error. This is printed

597 2.3.1.1 `bfd_get_reloc_upper_bound'
598 ...................................
601 long bfd_get_reloc_upper_bound (bfd *abfd, asection *sect);
603 Return the number of bytes required to store the relocation information
604 associated with section SECT attached to bfd ABFD. If an error occurs,
607 2.3.1.2 `bfd_canonicalize_reloc'
608 ................................
611 long bfd_canonicalize_reloc
612 (bfd *abfd, asection *sec, arelent **loc, asymbol **syms);
614 Call the back end associated with the open BFD ABFD and translate the
615 external form of the relocation information attached to SEC into the
616 internal canonical form. Place the table into memory at LOC, which has
617 been preallocated, usually by a call to `bfd_get_reloc_upper_bound'.
618 Returns the number of relocs, or -1 on error.
620 The SYMS table is also needed for horrible internal magic reasons.
622 2.3.1.3 `bfd_set_reloc'
623 .......................
627 (bfd *abfd, asection *sec, arelent **rel, unsigned int count);
629 Set the relocation pointer and count within section SEC to the values
630 REL and COUNT. The argument ABFD is ignored.
632 2.3.1.4 `bfd_set_file_flags'
633 ............................
636 bfd_boolean bfd_set_file_flags (bfd *abfd, flagword flags);
638 Set the flag word in the BFD ABFD to the value FLAGS.
641 * `bfd_error_wrong_format' - The target bfd was not of object format.
643 * `bfd_error_invalid_operation' - The target bfd was open for
646 * `bfd_error_invalid_operation' - The flag word contained a bit
647 which was not applicable to the type of file. E.g., an attempt
648 was made to set the `D_PAGED' bit on a BFD format which does not
649 support demand paging.
651 2.3.1.5 `bfd_get_arch_size'
652 ...........................

657 Returns the architecture address size, in bits, as determined by the
658 object file's format. For ELF, this information is included in the
662 Returns the arch size in bits if known, `-1' otherwise.
664 2.3.1.6 `bfd_get_sign_extend_vma'
665 .................................
668 int bfd_get_sign_extend_vma (bfd *abfd);
670 Indicates if the target architecture "naturally" sign extends an
671 address. Some architectures implicitly sign extend address values when
672 they are converted to types larger than the size of an address. For
673 instance, bfd_get_start_address() will return an address sign extended
674 to fill a bfd_vma when this is the case.
677 Returns `1' if the target architecture is known to sign extend
678 addresses, `0' if the target architecture is known to not sign extend
679 addresses, and `-1' otherwise.
681 2.3.1.7 `bfd_set_start_address'
682 ...............................
685 bfd_boolean bfd_set_start_address (bfd *abfd, bfd_vma vma);
687 Make VMA the entry point of output BFD ABFD.
690 Returns `TRUE' on success, `FALSE' otherwise.
692 2.3.1.8 `bfd_get_gp_size'
693 .........................
696 unsigned int bfd_get_gp_size (bfd *abfd);
698 Return the maximum size of objects to be optimized using the GP
699 register under MIPS ECOFF. This is typically set by the `-G' argument
700 to the compiler, assembler or linker.
702 2.3.1.9 `bfd_set_gp_size'
703 .........................
706 void bfd_set_gp_size (bfd *abfd, unsigned int i);
708 Set the maximum size of objects to be optimized using the GP register
709 under ECOFF or MIPS ELF. This is typically set by the `-G' argument to

713 .......................
716 bfd_vma bfd_scan_vma (const char *string, const char **end, int base);
718 Convert, like `strtoul', a numerical expression STRING into a `bfd_vma'
719 integer, and return that integer. (Though without as many bells and
720 whistles as `strtoul'.) The expression is assumed to be unsigned
721 (i.e., positive). If given a BASE, it is used as the base for
722 conversion. A base of 0 causes the function to interpret the string in
723 hex if a leading "0x" or "0X" is found, otherwise in octal if a leading
724 zero is found, otherwise in decimal.
726 If the value would overflow, the maximum `bfd_vma' value is returned.

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

912 ............................
915 bfd_boolean bfd_preserve_save (bfd *, struct bfd_preserve *);
917 When testing an object for compatibility with a particular target
918 back-end, the back-end object_p function needs to set up certain fields
919 in the bfd on successfully recognizing the object. This typically
920 happens in a piecemeal fashion, with failures possible at many points.
921 On failure, the bfd is supposed to be restored to its initial state,
922 which is virtually impossible. However, restoring a subset of the bfd
923 state works in practice. This function stores the subset and
924 reinitializes the bfd.
926 2.3.1.18 `bfd_preserve_restore'
927 ...............................
930 void bfd_preserve_restore (bfd *, struct bfd_preserve *);
932 This function restores bfd state saved by bfd_preserve_save. If MARKER
933 is non-NULL in struct bfd_preserve then that block and all subsequently
934 bfd_alloc'd memory is freed.
936 2.3.1.19 `bfd_preserve_finish'
937 ..............................
940 void bfd_preserve_finish (bfd *, struct bfd_preserve *);
942 This function should be called when the bfd state saved by
943 bfd_preserve_save is no longer needed. ie. when the back-end object_p
944 function returns with success.
946 2.3.1.20 `struct bfd_iovec'
947 ...........................
950 The `struct bfd_iovec' contains the internal file I/O class. Each
951 `BFD' has an instance of this class and all file I/O is routed through
952 it (it is assumed that the instance implements all methods listed
956 /* To avoid problems with macros, a "b" rather than "f"
957 prefix is prepended to each method name. */
958 /* Attempt to read/write NBYTES on ABFD's IOSTREAM storing/fetching

965 /* Return the current IOSTREAM file offset, or -1 (setting `bfd_error'
966 if an error occurs. */
967 file_ptr (*btell) (struct bfd *abfd);
968 /* For the following, on successful completion a value of 0 is returned.
969 Otherwise, a value of -1 is returned (and `bfd_error' is set). */

973 int (*bstat) (struct bfd *abfd, struct stat *sb);
976 2.3.1.21 `bfd_get_mtime'
977 ........................
980 long bfd_get_mtime (bfd *abfd);
982 Return the file modification time (as read from the file system, or
983 from the archive header for archive members).
985 2.3.1.22 `bfd_get_size'
986 .......................
989 long bfd_get_size (bfd *abfd);
991 Return the file size (as read from file system) for the file associated
994 The initial motivation for, and use of, this routine is not so we
995 can get the exact size of the object the BFD applies to, since that
996 might not be generally possible (archive members for example). It
997 would be ideal if someone could eventually modify it so that such
998 results were guaranteed.
1000 Instead, we want to ask questions like "is this NNN byte sized
1001 object I'm about to try read from file offset YYY reasonable?" As as
1002 example of where we might do this, some object formats use string
1003 tables for which the first `sizeof (long)' bytes of the table contain
1004 the size of the table itself, including the size bytes. If an
1005 application tries to read what it thinks is one of these string tables,
1006 without some way to validate the size, and for some reason the size is
1007 wrong (byte swapping error, wrong location for the string table, etc.),
1008 the only clue is likely to be a read error when it tries to read the
1009 table, or a "virtual memory exhausted" error when it tries to allocate
1010 15 bazillon bytes of space for the 15 bazillon byte table it is about
1011 to read. This function at least allows us to answer the question, "is
1012 the size reasonable?".

1033 File: bfd.info, Node: Memory Usage, Next: Initialization, Prev: BFD front end, Up: BFD front end
1038 BFD keeps all of its internal structures in obstacks. There is one
1039 obstack per open BFD file, into which the current state is stored. When
1040 a BFD is closed, the obstack is deleted, and so everything which has
1041 been allocated by BFD for the closing file is thrown away.
1043 BFD does not free anything created by an application, but pointers
1044 into `bfd' structures become invalid on a `bfd_close'; for example,
1045 after a `bfd_close' the vector passed to `bfd_canonicalize_symtab' is
1046 still around, since it has been allocated by the application, but the
1047 data that it pointed to are lost.
1049 The general rule is to not close a BFD until all operations dependent
1050 upon data from the BFD have been completed, or all the data from within
1051 the file has been copied. To help with the management of memory, there
1052 is a function (`bfd_alloc_size') which returns the number of bytes in
1053 obstacks associated with the supplied BFD. This could be used to select
1054 the greediest open BFD, close it to reclaim the memory, perform some
1055 operation and reopen the BFD again, to get a fresh copy of the data

1064 2.5.1 Initialization functions
1065 ------------------------------
1067 These are the functions that handle initializing a BFD.
1073 void bfd_init (void);
1075 This routine must be called before any other BFD function to initialize
1076 magical internal data structures.
1079 File: bfd.info, Node: Sections, Next: Symbols, Prev: Initialization, Up: BFD front end
1084 The raw data contained within a BFD is maintained through the section
1085 abstraction. A single BFD may have any number of sections. It keeps
1086 hold of them by pointing to the first; each one points to the next in
1089 Sections are supported in BFD in `section.c'.

1096 * section prototypes::
1099 File: bfd.info, Node: Section Input, Next: Section Output, Prev: Sections, Up: Sections
1104 When a BFD is opened for reading, the section structures are created
1105 and attached to the BFD.
1107 Each section has a name which describes the section in the outside
1108 world--for example, `a.out' would contain at least three sections,
1109 called `.text', `.data' and `.bss'.
1111 Names need not be unique; for example a COFF file may have several
1112 sections named `.data'.
1114 Sometimes a BFD will contain more than the "natural" number of
1115 sections. A back end may attach other sections containing constructor
1116 data, or an application may add a section (using `bfd_make_section') to
1117 the sections attached to an already open BFD. For example, the linker
1118 creates an extra section `COMMON' for each input file's BFD to hold
1119 information about common storage.
1121 The raw data is not necessarily read in when the section descriptor
1122 is created. Some targets may leave the data in place until a
1123 `bfd_get_section_contents' call is made. Other back ends may read in
1124 all the data at once. For example, an S-record file has to be read
1125 once to determine the size of the data. An IEEE-695 file doesn't
1126 contain raw data in sections, but data and relocation expressions
1127 intermixed, so the data area has to be parsed to get out the data and

1133 2.6.2 Section output
1134 --------------------
1136 To write a new object style BFD, the various sections to be written
1137 have to be created. They are attached to the BFD in the same way as
1138 input sections; data is written to the sections using
1139 `bfd_set_section_contents'.
1141 Any program that creates or combines sections (e.g., the assembler
1142 and linker) must use the `asection' fields `output_section' and
1143 `output_offset' to indicate the file sections to which each section
1144 must be written. (If the section is being created from scratch,
1145 `output_section' should probably point to the section itself and
1146 `output_offset' should probably be zero.)
1148 The data to be written comes from input sections attached (via
1149 `output_section' pointers) to the output sections. The output section
1150 structure can be considered a filter for the input section: the output
1151 section determines the vma of the output data and the name, but the
1152 input section determines the offset into the output section of the data
1155 E.g., to create a section "O", starting at 0x100, 0x123 long,
1156 containing two subsections, "A" at offset 0x0 (i.e., at vma 0x100) and
1157 "B" at offset 0x20 (i.e., at vma 0x120) the `asection' structures would
1163 output_section -----------> section name "O"
1165 section name "B" | size 0x123
1166 output_offset 0x20 |
1168 output_section --------|
1173 The data within a section is stored in a "link_order". These are much
1174 like the fixups in `gas'. The link_order abstraction allows a section
1175 to grow and shrink within itself.
1177 A link_order knows how big it is, and which is the next link_order
1178 and where the raw data for it is; it also points to a list of
1179 relocations which apply to it.
1181 The link_order is used by the linker to perform relaxing on final
1182 code. The compiler creates code which is as big as necessary to make
1183 it work without relaxing, and the user can select whether to relax.
1184 Sometimes relaxing takes a lot of time. The linker runs around the
1185 relocations to see if any are attached to data which can be shrunk, if
1186 so it does it on a link_order by link_order basis.

1727 2.6.5 Section prototypes
1728 ------------------------
1730 These are the functions exported by the section handling part of BFD.
1732 2.6.5.1 `bfd_section_list_clear'
1733 ................................
1736 void bfd_section_list_clear (bfd *);
1738 Clears the section list, and also resets the section count and hash
1741 2.6.5.2 `bfd_get_section_by_name'
1742 .................................
1745 asection *bfd_get_section_by_name (bfd *abfd, const char *name);
1747 Run through ABFD and return the one of the `asection's whose name
1748 matches NAME, otherwise `NULL'. *Note Sections::, for more information.
1750 This should only be used in special cases; the normal way to process
1751 all sections of a given name is to use `bfd_map_over_sections' and
1752 `strcmp' on the name (or better yet, base it on the section flags or
1753 something else) for each section.
1755 2.6.5.3 `bfd_get_section_by_name_if'
1756 ....................................
1759 asection *bfd_get_section_by_name_if
1762 bfd_boolean (*func) (bfd *abfd, asection *sect, void *obj),
1765 Call the provided function FUNC for each section attached to the BFD
1766 ABFD whose name matches NAME, passing OBJ as an argument. The function
1767 will be called as if by
1769 func (abfd, the_section, obj);
1771 It returns the first section for which FUNC returns true, otherwise
1774 2.6.5.4 `bfd_get_unique_section_name'
1775 .....................................
1778 char *bfd_get_unique_section_name
1779 (bfd *abfd, const char *templat, int *count);
1781 Invent a section name that is unique in ABFD by tacking a dot and a
1782 digit suffix onto the original TEMPLAT. If COUNT is non-NULL, then it
1783 specifies the first number tried as a suffix to generate a unique name.
1784 The value pointed to by COUNT will be incremented in this case.
1786 2.6.5.5 `bfd_make_section_old_way'
1787 ..................................
1790 asection *bfd_make_section_old_way (bfd *abfd, const char *name);
1792 Create a new empty section called NAME and attach it to the end of the
1793 chain of sections for the BFD ABFD. An attempt to create a section with
1794 a name which is already in use returns its pointer without changing the
1797 It has the funny name since this is the way it used to be before it
1800 Possible errors are:
1801 * `bfd_error_invalid_operation' - If output has already started for
1804 * `bfd_error_no_memory' - If memory allocation fails.
1806 2.6.5.6 `bfd_make_section_anyway_with_flags'
1807 ............................................
1810 asection *bfd_make_section_anyway_with_flags
1811 (bfd *abfd, const char *name, flagword flags);
1813 Create a new empty section called NAME and attach it to the end of the
1814 chain of sections for ABFD. Create a new section even if there is
1815 already a section with that name. Also set the attributes of the new
1816 section to the value FLAGS.
1818 Return `NULL' and set `bfd_error' on error; possible errors are:
1819 * `bfd_error_invalid_operation' - If output has already started for
1822 * `bfd_error_no_memory' - If memory allocation fails.
1824 2.6.5.7 `bfd_make_section_anyway'
1825 .................................
1828 asection *bfd_make_section_anyway (bfd *abfd, const char *name);
1830 Create a new empty section called NAME and attach it to the end of the
1831 chain of sections for ABFD. Create a new section even if there is
1832 already a section with that name.
1834 Return `NULL' and set `bfd_error' on error; possible errors are:
1835 * `bfd_error_invalid_operation' - If output has already started for
1838 * `bfd_error_no_memory' - If memory allocation fails.
1840 2.6.5.8 `bfd_make_section_with_flags'
1841 .....................................
1844 asection *bfd_make_section_with_flags
1845 (bfd *, const char *name, flagword flags);
1847 Like `bfd_make_section_anyway', but return `NULL' (without calling
1848 bfd_set_error ()) without changing the section chain if there is
1849 already a section named NAME. Also set the attributes of the new
1850 section to the value FLAGS. If there is an error, return `NULL' and set
1853 2.6.5.9 `bfd_make_section'
1854 ..........................
1857 asection *bfd_make_section (bfd *, const char *name);
1859 Like `bfd_make_section_anyway', but return `NULL' (without calling
1860 bfd_set_error ()) without changing the section chain if there is
1861 already a section named NAME. If there is an error, return `NULL' and
1864 2.6.5.10 `bfd_set_section_flags'
1865 ................................
1868 bfd_boolean bfd_set_section_flags
1869 (bfd *abfd, asection *sec, flagword flags);
1871 Set the attributes of the section SEC in the BFD ABFD to the value
1872 FLAGS. Return `TRUE' on success, `FALSE' on error. Possible error
1875 * `bfd_error_invalid_operation' - The section cannot have one or
1876 more of the attributes requested. For example, a .bss section in
1877 `a.out' may not have the `SEC_HAS_CONTENTS' field set.
1879 2.6.5.11 `bfd_map_over_sections'
1880 ................................
1883 void bfd_map_over_sections
1885 void (*func) (bfd *abfd, asection *sect, void *obj),
1888 Call the provided function FUNC for each section attached to the BFD
1889 ABFD, passing OBJ as an argument. The function will be called as if by
1891 func (abfd, the_section, obj);
1893 This is the preferred method for iterating over sections; an
1894 alternative would be to use a loop:
1897 for (p = abfd->sections; p != NULL; p = p->next)
1900 2.6.5.12 `bfd_sections_find_if'
1901 ...............................
1904 asection *bfd_sections_find_if
1906 bfd_boolean (*operation) (bfd *abfd, asection *sect, void *obj),
1909 Call the provided function OPERATION for each section attached to the
1910 BFD ABFD, passing OBJ as an argument. The function will be called as if
1913 operation (abfd, the_section, obj);
1915 It returns the first section for which OPERATION returns true.
1917 2.6.5.13 `bfd_set_section_size'
1918 ...............................
1921 bfd_boolean bfd_set_section_size
1922 (bfd *abfd, asection *sec, bfd_size_type val);
1924 Set SEC to the size VAL. If the operation is ok, then `TRUE' is
1925 returned, else `FALSE'.
1927 Possible error returns:
1928 * `bfd_error_invalid_operation' - Writing has started to the BFD, so
1929 setting the size is invalid.
1931 2.6.5.14 `bfd_set_section_contents'
1932 ...................................
1935 bfd_boolean bfd_set_section_contents
1936 (bfd *abfd, asection *section, const void *data,
1937 file_ptr offset, bfd_size_type count);
1939 Sets the contents of the section SECTION in BFD ABFD to the data
1940 starting in memory at DATA. The data is written to the output section
1941 starting at offset OFFSET for COUNT octets.
1943 Normally `TRUE' is returned, else `FALSE'. Possible error returns
1945 * `bfd_error_no_contents' - The output section does not have the
1946 `SEC_HAS_CONTENTS' attribute, so nothing can be written to it.
1949 This routine is front end to the back end function
1950 `_bfd_set_section_contents'.
1952 2.6.5.15 `bfd_get_section_contents'
1953 ...................................
1956 bfd_boolean bfd_get_section_contents
1957 (bfd *abfd, asection *section, void *location, file_ptr offset,
1958 bfd_size_type count);
1960 Read data from SECTION in BFD ABFD into memory starting at LOCATION.
1961 The data is read at an offset of OFFSET from the start of the input
1962 section, and is read for COUNT bytes.
1964 If the contents of a constructor with the `SEC_CONSTRUCTOR' flag set
1965 are requested or if the section does not have the `SEC_HAS_CONTENTS'
1966 flag set, then the LOCATION is filled with zeroes. If no errors occur,
1967 `TRUE' is returned, else `FALSE'.
1969 2.6.5.16 `bfd_malloc_and_get_section'
1970 .....................................
1973 bfd_boolean bfd_malloc_and_get_section
1974 (bfd *abfd, asection *section, bfd_byte **buf);
1976 Read all data from SECTION in BFD ABFD into a buffer, *BUF, malloc'd by
1979 2.6.5.17 `bfd_copy_private_section_data'
1980 ........................................
1983 bfd_boolean bfd_copy_private_section_data
1984 (bfd *ibfd, asection *isec, bfd *obfd, asection *osec);
1986 Copy private section information from ISEC in the BFD IBFD to the
1987 section OSEC in the BFD OBFD. Return `TRUE' on success, `FALSE' on
1988 error. Possible error returns are:
1990 * `bfd_error_no_memory' - Not enough memory exists to create private
1993 #define bfd_copy_private_section_data(ibfd, isection, obfd, osection) \
1994 BFD_SEND (obfd, _bfd_copy_private_section_data, \
1995 (ibfd, isection, obfd, osection))
1997 2.6.5.18 `bfd_generic_is_group_section'
1998 .......................................
2001 bfd_boolean bfd_generic_is_group_section (bfd *, const asection *sec);
2003 Returns TRUE if SEC is a member of a group.
2005 2.6.5.19 `bfd_generic_discard_group'
2006 ....................................
2009 bfd_boolean bfd_generic_discard_group (bfd *abfd, asection *group);
2011 Remove all members of GROUP from the output.

2022 requests the symbol table, BFD reads the table in the native form and
2023 translates parts of it into the internal format. To maintain more than
2024 the information passed to applications, some targets keep some
2025 information "behind the scenes" in a structure only the particular back
2026 end knows about. For example, the coff back end keeps the original
2027 symbol table structure as well as the canonical structure when a BFD is
2028 read in. On output, the coff back end can reconstruct the output symbol
2029 table so that no information is lost, even information unique to coff
2030 which BFD doesn't know or understand. If a coff symbol table were read,
2031 but were written through an a.out back end, all the coff specific
2032 information would be lost. The symbol table of a BFD is not necessarily
2033 read in until a canonicalize request is made. Then the BFD back end
2034 fills in a table provided by the application with pointers to the
2035 canonical information. To output symbols, the application provides BFD
2036 with a table of pointers to pointers to `asymbol's. This allows
2037 applications like the linker to output a symbol as it was read, since
2038 the "behind the scenes" information will be still available.

2051 2.7.1 Reading symbols
2052 ---------------------
2054 There are two stages to reading a symbol table from a BFD: allocating
2055 storage, and the actual reading process. This is an excerpt from an
2056 application which reads the symbol table:
2058 long storage_needed;
2059 asymbol **symbol_table;
2060 long number_of_symbols;
2063 storage_needed = bfd_get_symtab_upper_bound (abfd);
2065 if (storage_needed < 0)
2068 if (storage_needed == 0)
2071 symbol_table = xmalloc (storage_needed);
2074 bfd_canonicalize_symtab (abfd, symbol_table);
2076 if (number_of_symbols < 0)
2079 for (i = 0; i < number_of_symbols; i++)
2080 process_symbol (symbol_table[i]);
2082 All storage for the symbols themselves is in an objalloc connected
2083 to the BFD; it is freed when the BFD is closed.

2088 2.7.2 Writing symbols
2089 ---------------------
2091 Writing of a symbol table is automatic when a BFD open for writing is
2092 closed. The application attaches a vector of pointers to pointers to
2093 symbols to the BFD being written, and fills in the symbol count. The
2094 close and cleanup code reads through the table provided and performs
2095 all the necessary operations. The BFD output code must always be
2096 provided with an "owned" symbol: one which has come from another BFD,
2097 or one which has been created using `bfd_make_empty_symbol'. Here is an
2098 example showing the creation of a symbol table with only one element:
2107 abfd = bfd_openw ("foo","a.out-sunos-big");
2108 bfd_set_format (abfd, bfd_object);
2109 new = bfd_make_empty_symbol (abfd);
2110 new->name = "dummy_symbol";
2111 new->section = bfd_make_section_old_way (abfd, ".text");
2112 new->flags = BSF_GLOBAL;
2113 new->value = 0x12345;
2118 bfd_set_symtab (abfd, ptrs, 1);
2125 00012345 A dummy_symbol
2127 Many formats cannot represent arbitrary symbol information; for
2128 instance, the `a.out' object format does not allow an arbitrary number
2129 of sections. A symbol pointing to a section which is not one of
2130 `.text', `.data' or `.bss' cannot be described.
2133 File: bfd.info, Node: Mini Symbols, Next: typedef asymbol, Prev: Writing Symbols, Up: Symbols
2138 Mini symbols provide read-only access to the symbol table. They use
2139 less memory space, but require more time to access. They can be useful
2140 for tools like nm or objdump, which may have to handle symbol tables of
2141 extremely large executables.
2143 The `bfd_read_minisymbols' function will read the symbols into
2144 memory in an internal form. It will return a `void *' pointer to a
2145 block of memory, a symbol count, and the size of each symbol. The
2146 pointer is allocated using `malloc', and should be freed by the caller
2147 when it is no longer needed.
2149 The function `bfd_minisymbol_to_symbol' will take a pointer to a
2150 minisymbol, and a pointer to a structure returned by
2151 `bfd_make_empty_symbol', and return a `asymbol' structure. The return
2152 value may or may not be the same as the value from
2153 `bfd_make_empty_symbol' which was passed in.

2448 File: bfd.info, Node: Archives, Next: Formats, Prev: Symbols, Up: BFD front end
2454 An archive (or library) is just another BFD. It has a symbol table,
2455 although there's not much a user program will do with it.
2457 The big difference between an archive BFD and an ordinary BFD is
2458 that the archive doesn't have sections. Instead it has a chain of BFDs
2459 that are considered its contents. These BFDs can be manipulated like
2460 any other. The BFDs contained in an archive opened for reading will
2461 all be opened for reading. You may put either input or output BFDs
2462 into an archive opened for output; they will be handled correctly when
2463 the archive is closed.
2465 Use `bfd_openr_next_archived_file' to step through the contents of
2466 an archive opened for input. You don't have to read the entire archive
2467 if you don't want to! Read it until you find what you want.
2469 Archive contents of output BFDs are chained through the `next'
2470 pointer in a BFD. The first one is findable through the `archive_head'
2471 slot of the archive. Set it with `bfd_set_archive_head' (q.v.). A
2472 given BFD may be in only one open output archive at a time.
2474 As expected, the BFD archive code is more general than the archive
2475 code of any given environment. BFD archives may contain files of
2476 different formats (e.g., a.out and coff) and even different
2477 architectures. You may even place archives recursively into archives!
2479 This can cause unexpected confusion, since some archive formats are
2480 more expressive than others. For instance, Intel COFF archives can
2481 preserve long filenames; SunOS a.out archives cannot. If you move a
2482 file from the first to the second format and back again, the filename
2483 may be truncated. Likewise, different a.out environments have different
2484 conventions as to how they truncate filenames, whether they preserve
2485 directory names in filenames, etc. When interoperating with native
2486 tools, be sure your files are homogeneous.
2488 Beware: most of these formats do not react well to the presence of
2489 spaces in filenames. We do the best we can, but can't always handle
2490 this case due to restrictions in the format of archives. Many Unix
2491 utilities are braindead in regards to spaces and such in filenames
2492 anyway, so this shouldn't be much of a restriction.
2494 Archives are supported in BFD in `archive.c'.

2500 .............................
2503 symindex bfd_get_next_mapent
2504 (bfd *abfd, symindex previous, carsym **sym);
2506 Step through archive ABFD's symbol table (if it has one). Successively
2507 update SYM with the next symbol's information, returning that symbol's
2508 (internal) index into the symbol table.
2510 Supply `BFD_NO_MORE_SYMBOLS' as the PREVIOUS entry to get the first
2511 one; returns `BFD_NO_MORE_SYMBOLS' when you've already got the last one.
2513 A `carsym' is a canonical archive symbol. The only user-visible
2514 element is its name, a null-terminated string.
2516 2.8.1.2 `bfd_set_archive_head'
2517 ..............................
2520 bfd_boolean bfd_set_archive_head (bfd *output, bfd *new_head);

2526 ......................................
2529 bfd *bfd_openr_next_archived_file (bfd *archive, bfd *previous);
2531 Provided a BFD, ARCHIVE, containing an archive and NULL, open an input
2532 BFD on the first contained element and returns that. Subsequent calls
2533 should pass the archive and the previous return value to return a
2534 created BFD to the next contained element. NULL is returned when there

2543 A format is a BFD concept of high level file contents type. The formats
2544 supported by BFD are:
2547 The BFD may contain data, symbols, relocations and debug info.
2550 The BFD contains other BFDs and an optional index.
2553 The BFD contains the result of an executable core dump.
2555 2.9.1 File format functions
2556 ---------------------------
2558 2.9.1.1 `bfd_check_format'
2559 ..........................
2562 bfd_boolean bfd_check_format (bfd *abfd, bfd_format format);
2564 Verify if the file attached to the BFD ABFD is compatible with the
2565 format FORMAT (i.e., one of `bfd_object', `bfd_archive' or `bfd_core').
2567 If the BFD has been set to a specific target before the call, only
2568 the named target and format combination is checked. If the target has
2569 not been set, or has been set to `default', then all the known target
2570 backends is interrogated to determine a match. If the default target
2571 matches, it is used. If not, exactly one target must recognize the
2572 file, or an error results.
2574 The function returns `TRUE' on success, otherwise `FALSE' with one
2575 of the following error codes:
2577 * `bfd_error_invalid_operation' - if `format' is not one of
2578 `bfd_object', `bfd_archive' or `bfd_core'.
2580 * `bfd_error_system_call' - if an error occured during a read - even
2581 some file mismatches can cause bfd_error_system_calls.
2583 * `file_not_recognised' - none of the backends recognised the file
2586 * `bfd_error_file_ambiguously_recognized' - more than one backend
2587 recognised the file format.
2589 2.9.1.2 `bfd_check_format_matches'
2590 ..................................
2593 bfd_boolean bfd_check_format_matches
2594 (bfd *abfd, bfd_format format, char ***matching);
2596 Like `bfd_check_format', except when it returns FALSE with `bfd_errno'
2597 set to `bfd_error_file_ambiguously_recognized'. In that case, if
2598 MATCHING is not NULL, it will be filled in with a NULL-terminated list
2599 of the names of the formats that matched, allocated with `malloc'.
2600 Then the user may choose a format and try again.
2602 When done with the list that MATCHING points to, the caller should
2605 2.9.1.3 `bfd_set_format'
2606 ........................
2609 bfd_boolean bfd_set_format (bfd *abfd, bfd_format format);
2611 This function sets the file format of the BFD ABFD to the format
2612 FORMAT. If the target set in the BFD does not support the format
2613 requested, the format is invalid, or the BFD is not open for writing,
2614 then an error occurs.
2616 2.9.1.4 `bfd_format_string'
2617 ...........................
2620 const char *bfd_format_string (bfd_format format);
2622 Return a pointer to a const string `invalid', `object', `archive',
2623 `core', or `unknown', depending upon the value of FORMAT.

2631 BFD maintains relocations in much the same way it maintains symbols:
2632 they are left alone until required, then read in en-masse and
2633 translated into an internal form. A common routine
2634 `bfd_perform_relocation' acts upon the canonical form to do the fixup.
2636 Relocations are maintained on a per section basis, while symbols are
2637 maintained on a per BFD basis.
2639 All that a back end has to do to fit the BFD interface is to create
2640 a `struct reloc_cache_entry' for each relocation in a particular

2695 bfd_size_type address;
2697 /* addend for relocation value. */
2700 /* Pointer to how to perform the required relocation. */
2701 reloc_howto_type *howto;
2706 Here is a description of each of the fields within an `arelent':
2709 The symbol table pointer points to a pointer to the symbol
2710 associated with the relocation request. It is the pointer into the
2711 table returned by the back end's `canonicalize_symtab' action. *Note
2712 Symbols::. The symbol is referenced through a pointer to a pointer so
2713 that tools like the linker can fix up all the symbols of the same name
2714 by modifying only one pointer. The relocation routine looks in the
2715 symbol and uses the base of the section the symbol is attached to and
2716 the value of the symbol as the initial relocation offset. If the symbol
2717 pointer is zero, then the section provided is looked up.
2720 The `address' field gives the offset in bytes from the base of the
2721 section data which owns the relocation record to the first byte of
2722 relocatable information. The actual data relocated will be relative to
2723 this point; for example, a relocation type which modifies the bottom
2724 two bytes of a four byte word would not touch the first byte pointed to
2725 in a big endian world.
2728 The `addend' is a value provided by the back end to be added (!) to
2729 the relocation offset. Its interpretation is dependent upon the howto.
2730 For example, on the 68k the code:
2735 return foo[0x12345678];
2738 Could be compiled into:
2746 This could create a reloc pointing to `foo', but leave the offset in
2747 the data, something like:
2749 RELOCATION RECORDS FOR [.text]:
2753 00000000 4e56 fffc ; linkw fp,#-4
2754 00000004 1039 1234 5678 ; moveb @#12345678,d0
2755 0000000a 49c0 ; extbl d0
2756 0000000c 4e5e ; unlk fp
2759 Using coff and an 88k, some instructions don't have enough space in
2760 them to represent the full address range, and pointers have to be
2761 loaded in two parts. So you'd get something like:
2763 or.u r13,r0,hi16(_foo+0x12345678)
2764 ld.b r2,r13,lo16(_foo+0x12345678)
2767 This should create two relocs, both pointing to `_foo', and with
2768 0x12340000 in their addend field. The data would consist of:
2770 RELOCATION RECORDS FOR [.text]:
2772 00000002 HVRT16 _foo+0x12340000
2773 00000006 LVRT16 _foo+0x12340000
2775 00000000 5da05678 ; or.u r13,r0,0x5678
2776 00000004 1c4d5678 ; ld.b r2,r13,0x5678
2777 00000008 f400c001 ; jmp r1
2779 The relocation routine digs out the value from the data, adds it to
2780 the addend to get the original offset, and then adds the value of
2781 `_foo'. Note that all 32 bits have to be kept around somewhere, to cope
2782 with carry from bit 15 to bit 16.
2784 One further example is the sparc and the a.out format. The sparc has
2785 a similar problem to the 88k, in that some instructions don't have room
2786 for an entire offset, but on the sparc the parts are created in odd
2787 sized lumps. The designers of the a.out format chose to not use the
2788 data within the section for storing part of the offset; all the offset
2789 is kept within the reloc. Anything in the data should be ignored.
2792 sethi %hi(_foo+0x12345678),%g2
2793 ldsb [%g2+%lo(_foo+0x12345678)],%i0
2797 Both relocs contain a pointer to `foo', and the offsets contain junk.
2799 RELOCATION RECORDS FOR [.text]:
2801 00000004 HI22 _foo+0x12345678
2802 00000008 LO10 _foo+0x12345678
2804 00000000 9de3bf90 ; save %sp,-112,%sp
2805 00000004 05000000 ; sethi %hi(_foo+0),%g2
2806 00000008 f048a000 ; ldsb [%g2+%lo(_foo+0)],%i0
2807 0000000c 81c7e008 ; ret
2808 00000010 81e80000 ; restore
2811 The `howto' field can be imagined as a relocation instruction. It is
2812 a pointer to a structure which contains information on what to do with
2813 all of the other information in the reloc record and data section. A
2814 back end would normally have a relocation instruction set and turn
2815 relocations into pointers to the correct structure on input - but it
2816 would be possible to create each howto field on demand.

2978 2.10.1.4 `bfd_get_reloc_size'
2979 .............................
2982 unsigned int bfd_get_reloc_size (reloc_howto_type *);
2984 For a reloc_howto_type that operates on a fixed number of bytes, this
2985 returns the number of bytes operated on.

2988 ........................
2991 How relocs are tied together in an `asection':

3000 .............................
3003 bfd_reloc_status_type bfd_check_overflow
3004 (enum complain_overflow how,
3005 unsigned int bitsize,
3006 unsigned int rightshift,
3007 unsigned int addrsize,
3008 bfd_vma relocation);
3010 Perform overflow checking on RELOCATION which has BITSIZE significant
3011 bits and will be shifted right by RIGHTSHIFT bits, on a machine with
3012 addresses containing ADDRSIZE significant bits. The result is either of
3013 `bfd_reloc_ok' or `bfd_reloc_overflow'.
3015 2.10.1.7 `bfd_perform_relocation'

3019 bfd_reloc_status_type bfd_perform_relocation
3021 arelent *reloc_entry,
3023 asection *input_section,
3025 char **error_message);
3027 If OUTPUT_BFD is supplied to this function, the generated image will be
3028 relocatable; the relocations are copied to the output file after they
3029 have been changed to reflect the new state of the world. There are two
3030 ways of reflecting the results of partial linkage in an output file: by
3031 modifying the output data in place, and by modifying the relocation
3032 record. Some native formats (e.g., basic a.out and basic coff) have no
3033 way of specifying an addend in the relocation type, so the addend has
3034 to go in the output data. This is no big deal since in these formats
3035 the output data slot will always be big enough for the addend. Complex
3036 reloc types with addends were invented to solve just this problem. The
3037 ERROR_MESSAGE argument is set to an error message if this return
3038 `bfd_reloc_dangerous'.
3040 2.10.1.8 `bfd_install_relocation'
3041 .................................

3046 arelent *reloc_entry,
3047 void *data, bfd_vma data_start,
3048 asection *input_section,
3049 char **error_message);
3051 This looks remarkably like `bfd_perform_relocation', except it does not
3052 expect that the section contents have been filled in. I.e., it's
3053 suitable for use when creating, rather than applying a relocation.
3055 For now, this function should be considered reserved for the

3061 2.10.2 The howto manager
3062 ------------------------
3064 When an application wants to create a relocation, but doesn't know what
3065 the target machine might call it, it can find out by using this bit of
3068 2.10.2.1 `bfd_reloc_code_type'
3069 ..............................
3072 The insides of a reloc code. The idea is that, eventually, there will
3073 be one enumerator for every type of relocation we ever do. Pass one of
3074 these values to `bfd_reloc_type_lookup', and it'll return a howto
3077 This does mean that the application must determine the correct
3078 enumerator value; you can't get a howto pointer from a random set of
3081 Here are the possible values for `enum bfd_reloc_code_real':

3099 address of the relocation itself; sometimes they are relative to
3100 the start of the section containing the relocation. It depends on
3101 the specific target.

3152 i.e., byte displacements shifted right two bits. The 30-bit word
3153 displacement (<<32_PCREL_S2>> - 32 bits, shifted 2) is used on the
3154 SPARC. (SPARC tools generally refer to this as <<WDISP30>>.) The

3261 For GPDISP_LO16 ("ignore") relocations, the symbol is handled as
3262 with GPDISP_HI16 relocs. The addend is ignored when writing the
3263 relocations out, and is filled in with the file's GP value on
3264 reading, for convenience.
3266 -- : BFD_RELOC_ALPHA_GPDISP
3267 The ELF GPDISP relocation is exactly the same as the GPDISP_HI16
3268 relocation except that there is no accompanying GPDISP_LO16
3271 -- : BFD_RELOC_ALPHA_LITERAL
3272 -- : BFD_RELOC_ALPHA_ELF_LITERAL
3273 -- : BFD_RELOC_ALPHA_LITUSE
3274 The Alpha LITERAL/LITUSE relocs are produced by a symbol reference;
3275 the assembler turns it into a LDQ instruction to load the address
3276 of the symbol, and then fills in a register in the real
3279 The LITERAL reloc, at the LDQ instruction, refers to the .lita
3280 section symbol. The addend is ignored when writing, but is filled
3281 in with the file's GP value on reading, for convenience, as with
3282 the GPDISP_LO16 reloc.
3284 The ELF_LITERAL reloc is somewhere between 16_GOTOFF and
3285 GPDISP_LO16. It should refer to the symbol to be referenced, as
3286 with 16_GOTOFF, but it generates output not based on the position
3287 within the .got section, but relative to the GP value chosen for
3288 the file during the final link stage.
3290 The LITUSE reloc, on the instruction using the loaded address,
3291 gives information to the linker that it might be able to use to
3292 optimize away some literal section references. The symbol is
3293 ignored (read as the absolute section symbol), and the "addend"
3294 indicates the type of instruction using the register: 1 - "memory"
3295 fmt insn 2 - byte-manipulation (byte offset reg) 3 - jsr (target
3298 -- : BFD_RELOC_ALPHA_HINT
3299 The HINT relocation indicates a value that should be filled into
3300 the "hint" field of a jmp/jsr/ret instruction, for possible branch-
3301 prediction logic which may be provided on some processors.
3303 -- : BFD_RELOC_ALPHA_LINKAGE
3304 The LINKAGE relocation outputs a linkage pair in the object file,
3305 which is filled by the linker.
3307 -- : BFD_RELOC_ALPHA_CODEADDR
3308 The CODEADDR relocation outputs a STO_CA in the object file, which
3309 is filled by the linker.

3317 Like BFD_RELOC_23_PCREL_S2, except that the source and target must

4545 These two relocations are used by the linker to determine which of
4546 the entries in a C++ virtual function table are actually used.
4547 When the -gc-sections option is given, the linker will zero out
4548 the entries that are not used, so that the code for those
4549 functions need not be included in the output.
4551 VTABLE_INHERIT is a zero-space relocation used to describe to the
4552 linker the inheritance tree of a C++ virtual function table. The
4553 relocation's symbol should be the parent class' vtable, and the
4554 relocation should be located at the child vtable.
4556 VTABLE_ENTRY is a zero-space relocation that describes the use of a
4557 virtual function table entry. The reloc's symbol should refer to
4558 the table of the class mentioned in the code. Off of that base,
4559 an offset describes the entry that is being used. For Rela hosts,
4560 this offset is stored in the reloc's addend. For Rel hosts, we
4561 are forced to put this offset in the reloc's section offset.

5089 bfd_boolean core_file_matches_executable_p
5090 (bfd *core_bfd, bfd *exec_bfd);
5092 Return `TRUE' if the core file attached to CORE_BFD was generated by a
5093 run of the executable file attached to EXEC_BFD, `FALSE' otherwise.

5106 Note: When not able to determine the core file failing command or
5107 the executable name, we still return TRUE even though we're not sure
5108 that core file and executable match. This is to avoid generating a
5109 false warning in situations where we really don't know whether they
5113 File: bfd.info, Node: Targets, Next: Architectures, Prev: Core Files, Up: BFD front end
5119 Each port of BFD to a different machine requires the creation of a
5120 target back end. All the back end provides to the root part of BFD is a
5121 structure containing pointers to functions which perform certain low
5122 level operations on files. BFD translates the applications's requests
5123 through a pointer into calls to the back end routines.
5125 When a file is opened with `bfd_openr', its format and target are
5126 unknown. BFD uses various mechanisms to determine how to interpret the
5127 file. The operations performed are:
5129 * Create a BFD by calling the internal routine `_bfd_new_bfd', then
5130 call `bfd_find_target' with the target string supplied to
5131 `bfd_openr' and the new BFD pointer.
5133 * If a null target string was provided to `bfd_find_target', look up
5134 the environment variable `GNUTARGET' and use that as the target
5137 * If the target string is still `NULL', or the target string is
5138 `default', then use the first item in the target vector as the
5139 target type, and set `target_defaulted' in the BFD to cause
5140 `bfd_check_format' to loop through all the targets. *Note
5141 bfd_target::. *Note Formats::.
5143 * Otherwise, inspect the elements in the target vector one by one,
5144 until a match on target name is found. When found, use it.
5146 * Otherwise return the error `bfd_error_invalid_target' to
5149 * `bfd_openr' attempts to open the file using `bfd_open_file', and
5151 Once the BFD has been opened and the target selected, the file
5152 format may be determined. This is done by calling `bfd_check_format' on
5153 the BFD with a suggested format. If `target_defaulted' has been set,
5154 each possible target type is tried to see if it recognizes the
5155 specified format. `bfd_check_format' returns `TRUE' when the caller
5163 File: bfd.info, Node: bfd_target, Prev: Targets, Up: Targets
5169 This structure contains everything that BFD knows about a target. It
5170 includes things like its byte order, name, and which routines to call
5171 to do various operations.
5173 Every BFD points to a target structure with its `xvec' member.
5175 The macros below are used to dispatch to functions through the
5176 `bfd_target' vector. They are used in a number of macros further down
5177 in `bfd.h', and are also used when calling various routines by hand
5178 inside the BFD implementation. The ARGLIST argument must be
5179 parenthesized; it contains all the arguments to the called function.
5181 They make the documentation (more) unpleasant to read, so if someone
5182 wants to fix this and not break the above, please do.
5183 #define BFD_SEND(bfd, message, arglist) \

5193 For operations which index on the BFD format:

5202 (bfd_assert (__FILE__,__LINE__), NULL))
5204 This is the structure which defines the type of BFD this is. The
5205 `xvec' member of the struct `bfd' itself points here. Each module that
5206 implements access to a different target under BFD, defines one of these.
5208 FIXME, these names should be rationalised with the names of the
5209 entry points which call them. Too bad we can't have one macro to define

5592 Set the default target vector to use when recognizing a BFD. This
5593 takes the name of the target, which may be a BFD target name or a
5594 configuration triplet.
5596 2.12.1.2 `bfd_find_target'

5602 Return a pointer to the transfer vector for the object target named
5603 TARGET_NAME. If TARGET_NAME is `NULL', choose the one in the
5604 environment variable `GNUTARGET'; if that is null or not defined, then
5605 choose the first entry in the target list. Passing in the string
5606 "default" or setting the environment variable to "default" will cause
5607 the first entry in the target list to be returned, and
5608 "target_defaulted" will be set in the BFD. This causes
5609 `bfd_check_format' to loop over all the targets to find the one that
5610 matches the file being read.
5612 2.12.1.3 `bfd_target_list'
5613 ..........................
5616 const char ** bfd_target_list (void);
5618 Return a freshly malloced NULL-terminated vector of the names of all
5619 the valid BFD targets. Do not modify the names.
5621 2.12.1.4 `bfd_seach_for_target'
5622 ...............................
5625 const bfd_target *bfd_search_for_target
5626 (int (*search_func) (const bfd_target *, void *),
5629 Return a pointer to the first transfer vector in the list of transfer
5630 vectors maintained by BFD that produces a non-zero result when passed
5631 to the function SEARCH_FUNC. The parameter DATA is passed, unexamined,
5632 to the search function.
5635 File: bfd.info, Node: Architectures, Next: Opening and Closing, Prev: Targets, Up: BFD front end
5640 BFD keeps one atom in a BFD describing the architecture of the data
5641 attached to the BFD: a pointer to a `bfd_arch_info_type'.
5643 Pointers to structures can be requested independently of a BFD so
5644 that an architecture's information can be interrogated without access
5647 The architecture information is provided by each architecture
5648 package. The set of default architectures is selected by the macro
5649 `SELECT_ARCHITECTURES'. This is normally set up in the
5650 `config/TARGET.mt' file of your choice. If the name is not defined,
5651 then all the architectures supported are included.
5653 When BFD starts up, all the architectures are called with an
5654 initialize method. It is up to the architecture back end to insert as
5655 many items into the list of architectures as it wants to; generally
5656 this would be one for each machine and one for the default case (an
5657 item with a machine field of 0).
5659 BFD's idea of an architecture is implemented in `archures.c'.
5661 2.13.1 bfd_architecture

5665 This enum gives the object file's CPU architecture, in a global
5666 sense--i.e., what processor family does it belong to? Another field
5667 indicates which processor within the family is in use. The machine
5668 gives a number which distinguishes different versions of the
5669 architecture, containing, for example, 2 and 3 for Intel i960 KA and
5670 i960 KB, and 68020 and 68030 for Motorola 68020 and 68030.

6017 2.13.2.1 `bfd_printable_name'
6018 .............................
6021 const char *bfd_printable_name (bfd *abfd);
6023 Return a printable string representing the architecture and machine
6024 from the pointer to the architecture info structure.

6027 ........................
6030 const bfd_arch_info_type *bfd_scan_arch (const char *string);
6032 Figure out if BFD supports any cpu which could be described with the
6033 name STRING. Return a pointer to an `arch_info' structure if a machine
6034 is found, otherwise NULL.
6036 2.13.2.3 `bfd_arch_list'

6040 const char **bfd_arch_list (void);
6042 Return a freshly malloced NULL-terminated vector of the names of all
6043 the valid BFD architectures. Do not modify the names.

6049 const bfd_arch_info_type *bfd_arch_get_compatible
6050 (const bfd *abfd, const bfd *bbfd, bfd_boolean accept_unknowns);
6052 Determine whether two BFDs' architectures and machine types are
6053 compatible. Calculates the lowest common denominator between the two
6054 architectures and machine types implied by the BFDs and returns a
6055 pointer to an `arch_info' structure describing the compatible machine.

6061 The `bfd_default_arch_struct' is an item of `bfd_arch_info_type' which
6062 has been initialized to a fairly generic state. A BFD starts life by
6063 pointing to this structure, until the correct back end has determined
6064 the real architecture of the file.

6082 Set the architecture and machine type in BFD ABFD to ARCH and MACH.
6083 Find the correct pointer to a structure and insert it into the
6084 `arch_info' pointer.
6086 2.13.2.8 `bfd_get_arch'
6087 .......................
6090 enum bfd_architecture bfd_get_arch (bfd *abfd);

6110 2.13.2.11 `bfd_arch_bits_per_address'
6111 .....................................
6114 unsigned int bfd_arch_bits_per_address (bfd *abfd);
6116 Return the number of bits in one of the BFD ABFD's architecture's
6119 2.13.2.12 `bfd_default_compatible'
6120 ..................................
6123 const bfd_arch_info_type *bfd_default_compatible
6124 (const bfd_arch_info_type *a, const bfd_arch_info_type *b);

6135 The default function for working out whether this is an architecture
6136 hit and a machine hit.
6138 2.13.2.14 `bfd_get_arch_info'
6139 .............................

6151 (enum bfd_architecture arch, unsigned long machine);
6153 Look for the architecture info structure which matches the arguments
6154 ARCH and MACHINE. A machine of 0 matches the machine/architecture

6173 unsigned int bfd_octets_per_byte (bfd *abfd);
6175 Return the number of octets (8-bit quantities) per target byte (minimum
6176 addressable unit). In most cases, this will be one, but some DSP

6194 2.14 Opening and closing BFDs
6195 =============================
6197 2.14.1 Functions for opening and closing
6198 ----------------------------------------
6200 2.14.1.1 `bfd_fopen'
6201 ....................
6204 bfd *bfd_fopen (const char *filename, const char *target,
6205 const char *mode, int fd);
6207 Open the file FILENAME with the target TARGET. Return a pointer to the
6208 created BFD. If FD is not -1, then `fdopen' is used to open the file;
6209 otherwise, `fopen' is used. MODE is passed directly to `fopen' or
6212 Calls `bfd_find_target', so TARGET is interpreted as by that
6215 The new BFD is marked as cacheable iff FD is -1.
6217 If `NULL' is returned then an error has occured. Possible errors
6218 are `bfd_error_no_memory', `bfd_error_invalid_target' or `system_call'
6221 2.14.1.2 `bfd_openr'
6222 ....................
6225 bfd *bfd_openr (const char *filename, const char *target);
6227 Open the file FILENAME (using `fopen') with the target TARGET. Return
6228 a pointer to the created BFD.
6230 Calls `bfd_find_target', so TARGET is interpreted as by that
6233 If `NULL' is returned then an error has occured. Possible errors
6234 are `bfd_error_no_memory', `bfd_error_invalid_target' or `system_call'
6237 2.14.1.3 `bfd_fdopenr'
6238 ......................
6241 bfd *bfd_fdopenr (const char *filename, const char *target, int fd);
6243 `bfd_fdopenr' is to `bfd_fopenr' much like `fdopen' is to `fopen'. It
6244 opens a BFD on a file already described by the FD supplied.
6246 When the file is later `bfd_close'd, the file descriptor will be
6247 closed. If the caller desires that this file descriptor be cached by
6248 BFD (opened as needed, closed as needed to free descriptors for other
6249 opens), with the supplied FD used as an initial file descriptor (but
6250 subject to closure at any time), call bfd_set_cacheable(bfd, 1) on the
6251 returned BFD. The default is to assume no caching; the file descriptor
6252 will remain open until `bfd_close', and will not be affected by BFD
6253 operations on other files.
6255 Possible errors are `bfd_error_no_memory',
6256 `bfd_error_invalid_target' and `bfd_error_system_call'.
6258 2.14.1.4 `bfd_openstreamr'
6259 ..........................
6262 bfd *bfd_openstreamr (const char *, const char *, void *);
6264 Open a BFD for read access on an existing stdio stream. When the BFD
6265 is passed to `bfd_close', the stream will be closed.
6267 2.14.1.5 `bfd_openr_iovec'
6268 ..........................
6271 bfd *bfd_openr_iovec (const char *filename, const char *target,
6272 void *(*open) (struct bfd *nbfd,
6273 void *open_closure),
6275 file_ptr (*pread) (struct bfd *nbfd,
6280 int (*close) (struct bfd *nbfd,
6283 Create and return a BFD backed by a read-only STREAM. The STREAM is
6284 created using OPEN, accessed using PREAD and destroyed using CLOSE.
6286 Calls `bfd_find_target', so TARGET is interpreted as by that
6289 Calls OPEN (which can call `bfd_zalloc' and `bfd_get_filename') to
6290 obtain the read-only stream backing the BFD. OPEN either succeeds
6291 returning the non-`NULL' STREAM, or fails returning `NULL' (setting
6294 Calls PREAD to request NBYTES of data from STREAM starting at OFFSET
6295 (e.g., via a call to `bfd_read'). PREAD either succeeds returning the
6296 number of bytes read (which can be less than NBYTES when end-of-file),
6297 or fails returning -1 (setting `bfd_error').
6299 Calls CLOSE when the BFD is later closed using `bfd_close'. CLOSE
6300 either succeeds returning 0, or fails returning -1 (setting
6303 If `bfd_openr_iovec' returns `NULL' then an error has occurred.
6304 Possible errors are `bfd_error_no_memory', `bfd_error_invalid_target'
6305 and `bfd_error_system_call'.
6307 2.14.1.6 `bfd_openw'
6308 ....................
6311 bfd *bfd_openw (const char *filename, const char *target);
6313 Create a BFD, associated with file FILENAME, using the file format
6314 TARGET, and return a pointer to it.
6316 Possible errors are `bfd_error_system_call', `bfd_error_no_memory',
6317 `bfd_error_invalid_target'.
6319 2.14.1.7 `bfd_close'
6320 ....................
6323 bfd_boolean bfd_close (bfd *abfd);
6325 Close a BFD. If the BFD was open for writing, then pending operations
6326 are completed and the file written out and closed. If the created file
6327 is executable, then `chmod' is called to mark it as such.
6329 All memory attached to the BFD is released.
6331 The file descriptor associated with the BFD is closed (even if it
6332 was passed in to BFD by `bfd_fdopenr').
6335 `TRUE' is returned if all is ok, otherwise `FALSE'.
6337 2.14.1.8 `bfd_close_all_done'
6338 .............................
6341 bfd_boolean bfd_close_all_done (bfd *);
6343 Close a BFD. Differs from `bfd_close' since it does not complete any
6344 pending operations. This routine would be used if the application had
6345 just used BFD for swapping and didn't want to use any of the writing
6348 If the created file is executable, then `chmod' is called to mark it
6351 All memory attached to the BFD is released.
6354 `TRUE' is returned if all is ok, otherwise `FALSE'.
6356 2.14.1.9 `bfd_create'
6357 .....................
6360 bfd *bfd_create (const char *filename, bfd *templ);
6362 Create a new BFD in the manner of `bfd_openw', but without opening a
6363 file. The new BFD takes the target from the target used by TEMPLATE.
6364 The format is always set to `bfd_object'.
6366 2.14.1.10 `bfd_make_writable'
6367 .............................
6370 bfd_boolean bfd_make_writable (bfd *abfd);
6372 Takes a BFD as created by `bfd_create' and converts it into one like as
6373 returned by `bfd_openw'. It does this by converting the BFD to
6374 BFD_IN_MEMORY. It's assumed that you will call `bfd_make_readable' on
6378 `TRUE' is returned if all is ok, otherwise `FALSE'.
6380 2.14.1.11 `bfd_make_readable'
6381 .............................
6384 bfd_boolean bfd_make_readable (bfd *abfd);
6386 Takes a BFD as created by `bfd_create' and `bfd_make_writable' and
6387 converts it into one like as returned by `bfd_openr'. It does this by
6388 writing the contents out to the memory buffer, then reversing the
6392 `TRUE' is returned if all is ok, otherwise `FALSE'.
6394 2.14.1.12 `bfd_alloc'
6395 .....................
6398 void *bfd_alloc (bfd *abfd, bfd_size_type wanted);
6400 Allocate a block of WANTED bytes of memory attached to `abfd' and
6401 return a pointer to it.
6403 2.14.1.13 `bfd_alloc2'
6404 ......................
6407 void *bfd_alloc2 (bfd *abfd, bfd_size_type nmemb, bfd_size_type size);
6409 Allocate a block of NMEMB elements of SIZE bytes each of memory
6410 attached to `abfd' and return a pointer to it.
6412 2.14.1.14 `bfd_zalloc'
6413 ......................
6416 void *bfd_zalloc (bfd *abfd, bfd_size_type wanted);
6418 Allocate a block of WANTED bytes of zeroed memory attached to `abfd'
6419 and return a pointer to it.
6421 2.14.1.15 `bfd_zalloc2'
6422 .......................
6425 void *bfd_zalloc2 (bfd *abfd, bfd_size_type nmemb, bfd_size_type size);
6427 Allocate a block of NMEMB elements of SIZE bytes each of zeroed memory
6428 attached to `abfd' and return a pointer to it.
6430 2.14.1.16 `bfd_calc_gnu_debuglink_crc32'
6431 ........................................
6434 unsigned long bfd_calc_gnu_debuglink_crc32
6435 (unsigned long crc, const unsigned char *buf, bfd_size_type len);
6437 Computes a CRC value as used in the .gnu_debuglink section. Advances
6438 the previously computed CRC value by computing and adding in the crc32
6439 for LEN bytes of BUF.
6442 Return the updated CRC32 value.
6444 2.14.1.17 `get_debug_link_info'
6445 ...............................
6448 char *get_debug_link_info (bfd *abfd, unsigned long *crc32_out);
6450 fetch the filename and CRC32 value for any separate debuginfo
6451 associated with ABFD. Return NULL if no such info found, otherwise
6452 return filename and update CRC32_OUT.
6454 2.14.1.18 `separate_debug_file_exists'
6455 ......................................
6458 bfd_boolean separate_debug_file_exists
6459 (char *name, unsigned long crc32);
6461 Checks to see if NAME is a file and if its contents match CRC32.
6463 2.14.1.19 `find_separate_debug_file'
6464 ....................................
6467 char *find_separate_debug_file (bfd *abfd);
6469 Searches ABFD for a reference to separate debugging information, scans
6470 various locations in the filesystem, including the file tree rooted at
6471 DEBUG_FILE_DIRECTORY, and returns a filename of such debugging
6472 information if the file is found and has matching CRC32. Returns NULL
6473 if no reference to debugging file exists, or file cannot be found.
6475 2.14.1.20 `bfd_follow_gnu_debuglink'
6476 ....................................
6479 char *bfd_follow_gnu_debuglink (bfd *abfd, const char *dir);
6481 Takes a BFD and searches it for a .gnu_debuglink section. If this
6482 section is found, it examines the section for the name and checksum of
6483 a '.debug' file containing auxiliary debugging information. It then
6484 searches the filesystem for this .debug file in some standard
6485 locations, including the directory tree rooted at DIR, and if found
6486 returns the full filename.
6488 If DIR is NULL, it will search a default path configured into libbfd
6489 at build time. [XXX this feature is not currently implemented].
6492 `NULL' on any errors or failure to locate the .debug file, otherwise a
6493 pointer to a heap-allocated string containing the filename. The caller
6494 is responsible for freeing this string.
6496 2.14.1.21 `bfd_create_gnu_debuglink_section'
6497 ............................................
6500 struct bfd_section *bfd_create_gnu_debuglink_section
6501 (bfd *abfd, const char *filename);
6503 Takes a BFD and adds a .gnu_debuglink section to it. The section is
6504 sized to be big enough to contain a link to the specified FILENAME.
6507 A pointer to the new section is returned if all is ok. Otherwise
6508 `NULL' is returned and bfd_error is set.
6510 2.14.1.22 `bfd_fill_in_gnu_debuglink_section'
6511 .............................................
6514 bfd_boolean bfd_fill_in_gnu_debuglink_section
6515 (bfd *abfd, struct bfd_section *sect, const char *filename);
6517 Takes a BFD and containing a .gnu_debuglink section SECT and fills in
6518 the contents of the section to contain a link to the specified
6519 FILENAME. The filename should be relative to the current directory.
6522 `TRUE' is returned if all is ok. Otherwise `FALSE' is returned and

6528 2.15 Implementation details
6529 ===========================
6531 2.15.1 Internal functions
6532 -------------------------
6535 These routines are used within BFD. They are not intended for export,
6536 but are documented here for completeness.
6538 2.15.1.1 `bfd_write_bigendian_4byte_int'
6539 ........................................
6542 bfd_boolean bfd_write_bigendian_4byte_int (bfd *, unsigned int);
6544 Write a 4 byte integer I to the output BFD ABFD, in big endian order
6545 regardless of what else is going on. This is useful in archives.
6547 2.15.1.2 `bfd_put_size'
6548 .......................
6550 2.15.1.3 `bfd_get_size'
6551 .......................
6554 These macros as used for reading and writing raw data in sections; each
6555 access (except for bytes) is vectored through the target format of the
6556 BFD and mangled accordingly. The mangling performs any necessary endian
6557 translations and removes alignment restrictions. Note that types
6558 accepted and returned by these macros are identical so they can be
6559 swapped around in macros--for example, `libaout.h' defines `GET_WORD'
6560 to either `bfd_get_32' or `bfd_get_64'.
6562 In the put routines, VAL must be a `bfd_vma'. If we are on a system
6563 without prototypes, the caller is responsible for making sure that is
6564 true, with a cast if necessary. We don't cast them in the macro
6565 definitions because that would prevent `lint' or `gcc -Wall' from
6566 detecting sins such as passing a pointer. To detect calling these with
6567 less than a `bfd_vma', use `gcc -Wconversion' on a host with 64 bit

6704 The file caching mechanism is embedded within BFD and allows the
6705 application to open as many BFDs as it wants without regard to the
6706 underlying operating system's file descriptor limit (often as low as 20
6707 open files). The module in `cache.c' maintains a least recently used
6708 list of `BFD_CACHE_MAX_OPEN' files, and exports the name
6709 `bfd_cache_lookup', which runs around and makes sure that the required
6710 BFD is open. If not, then it chooses a file to close, closes it and
6711 opens the one wanted, returning its file handle.

6765 2.17 Linker Functions
6766 =====================
6768 The linker uses three special entry points in the BFD target vector.
6769 It is not necessary to write special routines for these entry points
6770 when creating a new BFD back end, since generic versions are provided.
6771 However, writing them can speed up linking and make it use
6772 significantly less runtime memory.
6774 The first routine creates a hash table used by the other routines.
6775 The second routine adds the symbols from an object file to the hash
6776 table. The third routine takes all the object files and links them
6777 together to create the output file. These routines are designed so
6778 that the linker proper does not need to know anything about the symbols
6779 in the object files that it is linking. The linker merely arranges the
6780 sections as directed by the linker script and lets BFD handle the
6781 details of symbols and relocs.
6783 The second routine and third routines are passed a pointer to a
6784 `struct bfd_link_info' structure (defined in `bfdlink.h') which holds
6785 information relevant to the link, including the linker hash table
6786 (which was created by the first routine) and a set of callback
6787 functions to the linker proper.
6789 The generic linker routines are in `linker.c', and use the header
6790 file `genlink.h'. As of this writing, the only back ends which have
6791 implemented versions of these routines are a.out (in `aoutx.h') and
6792 ECOFF (in `ecoff.c'). The a.out routines are used as examples
6793 throughout this section.

6804 2.17.1 Creating a linker hash table
6805 -----------------------------------
6807 The linker routines must create a hash table, which must be derived
6808 from `struct bfd_link_hash_table' described in `bfdlink.c'. *Note Hash
6809 Tables::, for information on how to create a derived hash table. This
6810 entry point is called using the target vector of the linker output file.
6812 The `_bfd_link_hash_table_create' entry point must allocate and
6813 initialize an instance of the desired hash table. If the back end does
6814 not require any additional information to be stored with the entries in
6815 the hash table, the entry point may simply create a `struct
6816 bfd_link_hash_table'. Most likely, however, some additional
6817 information will be needed.
6819 For example, with each entry in the hash table the a.out linker
6820 keeps the index the symbol has in the final output file (this index
6821 number is used so that when doing a relocatable link the symbol index
6822 used in the output file can be quickly filled in when copying over a
6823 reloc). The a.out linker code defines the required structures and
6824 functions for a hash table derived from `struct bfd_link_hash_table'.
6825 The a.out linker hash table is created by the function
6826 `NAME(aout,link_hash_table_create)'; it simply allocates space for the
6827 hash table, initializes it, and returns a pointer to it.
6829 When writing the linker routines for a new back end, you will
6830 generally not know exactly which fields will be required until you have
6831 finished. You should simply create a new hash table which defines no
6832 additional fields, and then simply add fields as they become necessary.

6837 2.17.2 Adding symbols to the hash table
6838 ---------------------------------------
6840 The linker proper will call the `_bfd_link_add_symbols' entry point for
6841 each object file or archive which is to be linked (typically these are
6842 the files named on the command line, but some may also come from the
6843 linker script). The entry point is responsible for examining the file.
6844 For an object file, BFD must add any relevant symbol information to
6845 the hash table. For an archive, BFD must determine which elements of
6846 the archive should be used and adding them to the link.
6848 The a.out version of this entry point is
6849 `NAME(aout,link_add_symbols)'.

6860 2.17.2.1 Differing file formats
6861 ...............................
6863 Normally all the files involved in a link will be of the same format,
6864 but it is also possible to link together different format object files,
6865 and the back end must support that. The `_bfd_link_add_symbols' entry
6866 point is called via the target vector of the file to be added. This
6867 has an important consequence: the function may not assume that the hash
6868 table is the type created by the corresponding
6869 `_bfd_link_hash_table_create' vector. All the `_bfd_link_add_symbols'
6870 function can assume about the hash table is that it is derived from
6871 `struct bfd_link_hash_table'.
6873 Sometimes the `_bfd_link_add_symbols' function must store some
6874 information in the hash table entry to be used by the `_bfd_final_link'
6875 function. In such a case the `creator' field of the hash table must be
6876 checked to make sure that the hash table was created by an object file
6879 The `_bfd_final_link' routine must be prepared to handle a hash
6880 entry without any extra information added by the
6881 `_bfd_link_add_symbols' function. A hash entry without extra
6882 information will also occur when the linker script directs the linker
6883 to create a symbol. Note that, regardless of how a hash table entry is
6884 added, all the fields will be initialized to some sort of null value by
6885 the hash table entry initialization function.
6887 See `ecoff_link_add_externals' for an example of how to check the
6888 `creator' field before saving information (in this case, the ECOFF
6889 external symbol debugging information) in a hash table entry.

6894 2.17.2.2 Adding symbols from an object file
6895 ...........................................
6897 When the `_bfd_link_add_symbols' routine is passed an object file, it
6898 must add all externally visible symbols in that object file to the hash
6899 table. The actual work of adding the symbol to the hash table is
6900 normally handled by the function `_bfd_generic_link_add_one_symbol'.
6901 The `_bfd_link_add_symbols' routine is responsible for reading all the
6902 symbols from the object file and passing the correct information to
6903 `_bfd_generic_link_add_one_symbol'.
6905 The `_bfd_link_add_symbols' routine should not use
6906 `bfd_canonicalize_symtab' to read the symbols. The point of providing
6907 this routine is to avoid the overhead of converting the symbols into
6908 generic `asymbol' structures.
6910 `_bfd_generic_link_add_one_symbol' handles the details of combining
6911 common symbols, warning about multiple definitions, and so forth. It
6912 takes arguments which describe the symbol to add, notably symbol flags,
6913 a section, and an offset. The symbol flags include such things as
6914 `BSF_WEAK' or `BSF_INDIRECT'. The section is a section in the object
6915 file, or something like `bfd_und_section_ptr' for an undefined symbol
6916 or `bfd_com_section_ptr' for a common symbol.
6918 If the `_bfd_final_link' routine is also going to need to read the
6919 symbol information, the `_bfd_link_add_symbols' routine should save it
6920 somewhere attached to the object file BFD. However, the information
6921 should only be saved if the `keep_memory' field of the `info' argument
6922 is TRUE, so that the `-no-keep-memory' linker switch is effective.
6924 The a.out function which adds symbols from an object file is
6925 `aout_link_add_object_symbols', and most of the interesting work is in
6926 `aout_link_add_symbols'. The latter saves pointers to the hash tables
6927 entries created by `_bfd_generic_link_add_one_symbol' indexed by symbol
6928 number, so that the `_bfd_final_link' routine does not have to call the
6929 hash table lookup routine to locate the entry.

6934 2.17.2.3 Adding symbols from an archive
6935 .......................................
6937 When the `_bfd_link_add_symbols' routine is passed an archive, it must
6938 look through the symbols defined by the archive and decide which
6939 elements of the archive should be included in the link. For each such
6940 element it must call the `add_archive_element' linker callback, and it
6941 must add the symbols from the object file to the linker hash table.
6943 In most cases the work of looking through the symbols in the archive
6944 should be done by the `_bfd_generic_link_add_archive_symbols' function.
6945 This function builds a hash table from the archive symbol table and
6946 looks through the list of undefined symbols to see which elements
6947 should be included. `_bfd_generic_link_add_archive_symbols' is passed
6948 a function to call to make the final decision about adding an archive
6949 element to the link and to do the actual work of adding the symbols to
6950 the linker hash table.
6952 The function passed to `_bfd_generic_link_add_archive_symbols' must
6953 read the symbols of the archive element and decide whether the archive
6954 element should be included in the link. If the element is to be
6955 included, the `add_archive_element' linker callback routine must be
6956 called with the element as an argument, and the elements symbols must
6957 be added to the linker hash table just as though the element had itself
6958 been passed to the `_bfd_link_add_symbols' function.
6960 When the a.out `_bfd_link_add_symbols' function receives an archive,
6961 it calls `_bfd_generic_link_add_archive_symbols' passing
6962 `aout_link_check_archive_element' as the function argument.
6963 `aout_link_check_archive_element' calls `aout_link_check_ar_symbols'.
6964 If the latter decides to add the element (an element is only added if
6965 it provides a real, non-common, definition for a previously undefined
6966 or common symbol) it calls the `add_archive_element' callback and then
6967 `aout_link_check_archive_element' calls `aout_link_add_symbols' to
6968 actually add the symbols to the linker hash table.
6970 The ECOFF back end is unusual in that it does not normally call
6971 `_bfd_generic_link_add_archive_symbols', because ECOFF archives already
6972 contain a hash table of symbols. The ECOFF back end searches the
6973 archive itself to avoid the overhead of creating a new hash table.

6978 2.17.3 Performing the final link
6979 --------------------------------
6981 When all the input files have been processed, the linker calls the
6982 `_bfd_final_link' entry point of the output BFD. This routine is
6983 responsible for producing the final output file, which has several
6984 aspects. It must relocate the contents of the input sections and copy
6985 the data into the output sections. It must build an output symbol
6986 table including any local symbols from the input files and the global
6987 symbols from the hash table. When producing relocatable output, it must
6988 modify the input relocs and write them into the output file. There may
6989 also be object format dependent work to be done.
6991 The linker will also call the `write_object_contents' entry point
6992 when the BFD is closed. The two entry points must work together in
6993 order to produce the correct output file.
6995 The details of how this works are inevitably dependent upon the
6996 specific object file format. The a.out `_bfd_final_link' routine is
6997 `NAME(aout,final_link)'.

7011 Before the linker calls the `_bfd_final_link' entry point, it sets up
7012 some data structures for the function to use.
7014 The `input_bfds' field of the `bfd_link_info' structure will point
7015 to a list of all the input files included in the link. These files are
7016 linked through the `link_next' field of the `bfd' structure.
7018 Each section in the output file will have a list of `link_order'
7019 structures attached to the `map_head.link_order' field (the
7020 `link_order' structure is defined in `bfdlink.h'). These structures
7021 describe how to create the contents of the output section in terms of
7022 the contents of various input sections, fill constants, and,
7023 eventually, other types of information. They also describe relocs that
7024 must be created by the BFD backend, but do not correspond to any input
7025 file; this is used to support -Ur, which builds constructors while
7026 generating a relocatable object file.

7031 2.17.3.2 Relocating the section contents
7032 ........................................
7034 The `_bfd_final_link' function should look through the `link_order'
7035 structures attached to each section of the output file. Each
7036 `link_order' structure should either be handled specially, or it should
7037 be passed to the function `_bfd_default_link_order' which will do the
7038 right thing (`_bfd_default_link_order' is defined in `linker.c').
7040 For efficiency, a `link_order' of type `bfd_indirect_link_order'
7041 whose associated section belongs to a BFD of the same format as the
7042 output BFD must be handled specially. This type of `link_order'
7043 describes part of an output section in terms of a section belonging to
7044 one of the input files. The `_bfd_final_link' function should read the
7045 contents of the section and any associated relocs, apply the relocs to
7046 the section contents, and write out the modified section contents. If
7047 performing a relocatable link, the relocs themselves must also be
7048 modified and written out.
7050 The functions `_bfd_relocate_contents' and
7051 `_bfd_final_link_relocate' provide some general support for performing
7052 the actual relocations, notably overflow checking. Their arguments
7053 include information about the symbol the relocation is against and a
7054 `reloc_howto_type' argument which describes the relocation to perform.
7055 These functions are defined in `reloc.c'.
7057 The a.out function which handles reading, relocating, and writing
7058 section contents is `aout_link_input_section'. The actual relocation
7059 is done in `aout_link_input_section_std' and
7060 `aout_link_input_section_ext'.

7065 2.17.3.3 Writing the symbol table
7066 .................................
7068 The `_bfd_final_link' function must gather all the symbols in the input
7069 files and write them out. It must also write out all the symbols in
7070 the global hash table. This must be controlled by the `strip' and
7071 `discard' fields of the `bfd_link_info' structure.
7073 The local symbols of the input files will not have been entered into
7074 the linker hash table. The `_bfd_final_link' routine must consider
7075 each input file and include the symbols in the output file. It may be
7076 convenient to do this when looking through the `link_order' structures,
7077 or it may be done by stepping through the `input_bfds' list.
7079 The `_bfd_final_link' routine must also traverse the global hash
7080 table to gather all the externally visible symbols. It is possible
7081 that most of the externally visible symbols may be written out when
7082 considering the symbols of each input file, but it is still necessary
7083 to traverse the hash table since the linker script may have defined
7084 some symbols that are not in any of the input files.
7086 The `strip' field of the `bfd_link_info' structure controls which
7087 symbols are written out. The possible values are listed in
7088 `bfdlink.h'. If the value is `strip_some', then the `keep_hash' field
7089 of the `bfd_link_info' structure is a hash table of symbols to keep;
7090 each symbol should be looked up in this hash table, and only symbols
7091 which are present should be included in the output file.
7093 If the `strip' field of the `bfd_link_info' structure permits local
7094 symbols to be written out, the `discard' field is used to further
7095 controls which local symbols are included in the output file. If the
7096 value is `discard_l', then all local symbols which begin with a certain
7097 prefix are discarded; this is controlled by the
7098 `bfd_is_local_label_name' entry point.
7100 The a.out backend handles symbols by calling
7101 `aout_link_write_symbols' on each input BFD and then traversing the
7102 global hash table with the function `aout_link_write_other_symbol'. It
7103 builds a string table while writing out the symbols, which is written
7104 to the output file at the end of `NAME(aout,final_link)'.

7134 BFD provides a simple set of hash table functions. Routines are
7135 provided to initialize a hash table, to free a hash table, to look up a
7136 string in a hash table and optionally create an entry for it, and to
7137 traverse a hash table. There is currently no routine to delete an
7138 string from a hash table.
7140 The basic hash table does not permit any data to be stored with a
7141 string. However, a hash table is designed to present a base class from
7142 which other types of hash tables may be derived. These derived types
7143 may store additional information with the string. Hash tables were
7144 implemented in this way, rather than simply providing a data pointer in
7145 a hash table entry, because they were designed for use by the linker
7146 back ends. The linker may create thousands of hash table entries, and
7147 the overhead of allocating private data and storing and following
7148 pointers becomes noticeable.
7150 The basic hash table code is in `hash.c'.

7162 2.18.1 Creating and freeing a hash table
7163 ----------------------------------------
7165 To create a hash table, create an instance of a `struct bfd_hash_table'
7166 (defined in `bfd.h') and call `bfd_hash_table_init' (if you know
7167 approximately how many entries you will need, the function
7168 `bfd_hash_table_init_n', which takes a SIZE argument, may be used).
7169 `bfd_hash_table_init' returns `FALSE' if some sort of error occurs.
7171 The function `bfd_hash_table_init' take as an argument a function to
7172 use to create new entries. For a basic hash table, use the function
7173 `bfd_hash_newfunc'. *Note Deriving a New Hash Table Type::, for why
7174 you would want to use a different value for this argument.
7176 `bfd_hash_table_init' will create an objalloc which will be used to
7177 allocate new entries. You may allocate memory on this objalloc using
7178 `bfd_hash_allocate'.
7180 Use `bfd_hash_table_free' to free up all the memory that has been
7181 allocated for a hash table. This will not free up the `struct
7182 bfd_hash_table' itself, which you must provide.
7184 Use `bfd_hash_set_default_size' to set the default size of hash

7190 2.18.2 Looking up or entering a string
7191 --------------------------------------
7193 The function `bfd_hash_lookup' is used both to look up a string in the
7194 hash table and to create a new entry.
7196 If the CREATE argument is `FALSE', `bfd_hash_lookup' will look up a
7197 string. If the string is found, it will returns a pointer to a `struct
7198 bfd_hash_entry'. If the string is not found in the table
7199 `bfd_hash_lookup' will return `NULL'. You should not modify any of the
7200 fields in the returns `struct bfd_hash_entry'.
7202 If the CREATE argument is `TRUE', the string will be entered into
7203 the hash table if it is not already there. Either way a pointer to a
7204 `struct bfd_hash_entry' will be returned, either to the existing
7205 structure or to a newly created one. In this case, a `NULL' return
7206 means that an error occurred.
7208 If the CREATE argument is `TRUE', and a new entry is created, the
7209 COPY argument is used to decide whether to copy the string onto the
7210 hash table objalloc or not. If COPY is passed as `FALSE', you must be
7211 careful not to deallocate or modify the string as long as the hash table

7218 ------------------------------
7220 The function `bfd_hash_traverse' may be used to traverse a hash table,
7221 calling a function on each element. The traversal is done in a random
7224 `bfd_hash_traverse' takes as arguments a function and a generic
7225 `void *' pointer. The function is called with a hash table entry (a
7226 `struct bfd_hash_entry *') and the generic pointer passed to
7227 `bfd_hash_traverse'. The function must return a `boolean' value, which
7228 indicates whether to continue traversing the hash table. If the
7229 function returns `FALSE', `bfd_hash_traverse' will stop the traversal
7230 and return immediately.

7235 2.18.4 Deriving a new hash table type
7236 -------------------------------------
7238 Many uses of hash tables want to store additional information which
7239 each entry in the hash table. Some also find it convenient to store
7240 additional information with the hash table itself. This may be done
7241 using a derived hash table.
7243 Since C is not an object oriented language, creating a derived hash
7244 table requires sticking together some boilerplate routines with a few
7245 differences specific to the type of hash table you want to create.
7247 An example of a derived hash table is the linker hash table. The
7248 structures for this are defined in `bfdlink.h'. The functions are in
7251 You may also derive a hash table from an already derived hash table.
7252 For example, the a.out linker backend code uses a hash table derived
7253 from the linker hash table.

7264 2.18.4.1 Define the derived structures
7265 ......................................
7267 You must define a structure for an entry in the hash table, and a
7268 structure for the hash table itself.
7270 The first field in the structure for an entry in the hash table must
7271 be of the type used for an entry in the hash table you are deriving
7272 from. If you are deriving from a basic hash table this is `struct
7273 bfd_hash_entry', which is defined in `bfd.h'. The first field in the
7274 structure for the hash table itself must be of the type of the hash
7275 table you are deriving from itself. If you are deriving from a basic
7276 hash table, this is `struct bfd_hash_table'.
7278 For example, the linker hash table defines `struct
7279 bfd_link_hash_entry' (in `bfdlink.h'). The first field, `root', is of
7280 type `struct bfd_hash_entry'. Similarly, the first field in `struct
7281 bfd_link_hash_table', `table', is of type `struct bfd_hash_table'.
7284 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
7286 2.18.4.2 Write the derived creation routine
7287 ...........................................
7289 You must write a routine which will create and initialize an entry in
7290 the hash table. This routine is passed as the function argument to
7291 `bfd_hash_table_init'.
7293 In order to permit other hash tables to be derived from the hash
7294 table you are creating, this routine must be written in a standard way.
7296 The first argument to the creation routine is a pointer to a hash
7297 table entry. This may be `NULL', in which case the routine should
7298 allocate the right amount of space. Otherwise the space has already
7299 been allocated by a hash table type derived from this one.
7301 After allocating space, the creation routine must call the creation
7302 routine of the hash table type it is derived from, passing in a pointer
7303 to the space it just allocated. This will initialize any fields used
7304 by the base hash table.
7306 Finally the creation routine must initialize any local fields for
7307 the new hash table type.
7309 Here is a boilerplate example of a creation routine. FUNCTION_NAME
7310 is the name of the routine. ENTRY_TYPE is the type of an entry in the
7311 hash table you are creating. BASE_NEWFUNC is the name of the creation
7312 routine of the hash table type your hash table is derived from.
7314 struct bfd_hash_entry *
7315 FUNCTION_NAME (struct bfd_hash_entry *entry,
7316 struct bfd_hash_table *table,
7319 struct ENTRY_TYPE *ret = (ENTRY_TYPE *) entry;
7321 /* Allocate the structure if it has not already been allocated by a
7325 ret = bfd_hash_allocate (table, sizeof (* ret));
7330 /* Call the allocation method of the base class. */
7331 ret = ((ENTRY_TYPE *)
7332 BASE_NEWFUNC ((struct bfd_hash_entry *) ret, table, string));
7334 /* Initialize the local fields here. */
7336 return (struct bfd_hash_entry *) ret;
7339 The creation routine for the linker hash table, which is in `linker.c',
7340 looks just like this example. FUNCTION_NAME is
7341 `_bfd_link_hash_newfunc'. ENTRY_TYPE is `struct bfd_link_hash_entry'.
7342 BASE_NEWFUNC is `bfd_hash_newfunc', the creation routine for a basic
7345 `_bfd_link_hash_newfunc' also initializes the local fields in a
7346 linker hash table entry: `type', `written' and `next'.

7351 2.18.4.3 Write other derived routines
7352 .....................................
7354 You will want to write other routines for your new hash table, as well.
7356 You will want an initialization routine which calls the
7357 initialization routine of the hash table you are deriving from and
7358 initializes any other local fields. For the linker hash table, this is
7359 `_bfd_link_hash_table_init' in `linker.c'.
7361 You will want a lookup routine which calls the lookup routine of the
7362 hash table you are deriving from and casts the result. The linker hash
7363 table uses `bfd_link_hash_lookup' in `linker.c' (this actually takes an
7364 additional argument which it uses to decide how to return the looked up
7367 You may want a traversal routine. This should just call the
7368 traversal routine of the hash table you are deriving from with
7369 appropriate casts. The linker hash table uses `bfd_link_hash_traverse'
7372 These routines may simply be defined as macros. For example, the
7373 a.out backend linker hash table, which is derived from the linker hash
7374 table, uses macros for the lookup and traversal routines. These are
7375 `aout_link_hash_lookup' and `aout_link_hash_traverse' in aoutx.h.

7403 BFD supports a number of different flavours of a.out format, though the
7404 major differences are only the sizes of the structures on disk, and the
7405 shape of the relocation information.
7407 The support is split into a basic support file `aoutx.h' and other
7408 files which derive functions from the base. One derivation file is
7409 `aoutf1.h' (for a.out flavour 1), and adds to the basic a.out functions
7410 support for sun3, sun4, 386 and 29k a.out files, to create a target
7411 jump vector for a specific target.
7413 This information is further split out into more specific files for
7414 each machine, including `sunos.c' for sun3 and sun4, `newsos3.c' for
7415 the Sony NEWS, and `demo64.c' for a demonstration of a 64 bit a.out
7418 The base file `aoutx.h' defines general mechanisms for reading and
7419 writing records to and from disk and various other methods which BFD
7420 requires. It is included by `aout32.c' and `aout64.c' to form the names
7421 `aout_32_swap_exec_header_in', `aout_64_swap_exec_header_in', etc.
7423 As an example, this is what goes on to make the back end for a sun4,
7426 #define ARCH_SIZE 32
7429 Which exports names:
7432 aout_32_canonicalize_reloc
7433 aout_32_find_nearest_line
7435 aout_32_get_reloc_upper_bound
7440 #define TARGET_NAME "a.out-sunos-big"
7441 #define VECNAME sunos_big_vec
7444 requires all the names from `aout32.c', and produces the jump vector
7448 The file `host-aout.c' is a special case. It is for a large set of
7449 hosts that use "more or less standard" a.out files, and for which
7450 cross-debugging is not interesting. It uses the standard 32-bit a.out
7451 support routines, but determines the file offsets and addresses of the
7452 text, data, and BSS sections, the machine architecture and machine
7453 type, and the entry point address, in a host-dependent manner. Once
7454 these values have been determined, generic code is used to handle the
7457 When porting it to run on a new system, you must supply:
7461 HOST_MACHINE_ARCH (optional)
7462 HOST_MACHINE_MACHINE (optional)
7463 HOST_TEXT_START_ADDR
7466 in the file `../include/sys/h-XXX.h' (for your host). These values,
7467 plus the structures and macros defined in `a.out.h' on your host
7468 system, will produce a BFD target that will access ordinary a.out files
7469 on your host. To configure a new machine to use `host-aout.c', specify:
7471 TDEFAULTS = -DDEFAULT_VECTOR=host_aout_big_vec
7472 TDEPFILES= host-aout.o trad-core.o
7474 in the `config/XXX.mt' file, and modify `configure.in' to use the
7475 `XXX.mt' file (by setting "`bfd_target=XXX'") when your configuration
7482 The file `aoutx.h' provides for both the _standard_ and _extended_
7483 forms of a.out relocation records.
7485 The standard records contain only an address, a symbol index, and a
7486 type field. The extended records (used on 29ks and sparcs) also have a
7487 full integer for an addend.
7489 3.1.2 Internal entry points
7490 ---------------------------
7493 `aoutx.h' exports several routines for accessing the contents of an
7494 a.out file, which are gathered and exported in turn by various format
7495 specific files (eg sunos.c).

7507 byte stream memory image into the internal exec header structure EXECP.

7510 ........................................
7513 void aout_SIZE_swap_exec_header_out
7515 struct internal_exec *execp,
7516 struct external_exec *raw_bytes);
7518 Swap the information in an internal exec header structure EXECP into
7519 the buffer RAW_BYTES ready for writing to disk.

7527 struct internal_exec *execp,
7528 const bfd_target *(*callback_to_real_object_p) (bfd *));
7530 Some a.out variant thinks that the file open in ABFD checking is an
7531 a.out file. Do some more checking, and set up for access if it really
7532 is. Call back to the calling environment's "finish up" function just
7533 before returning, to handle any last-minute setup.

7589 BFD supports a number of different flavours of coff format. The major
7590 differences between formats are the sizes and alignments of fields in
7591 structures on disk, and the occasional extra field.
7593 Coff in all its varieties is implemented with a few common files and
7594 a number of implementation specific files. For example, The 88k bcs
7595 coff format is implemented in the file `coff-m88k.c'. This file
7596 `#include's `coff/m88k.h' which defines the external structure of the
7597 coff format for the 88k, and `coff/internal.h' which defines the
7598 internal structure. `coff-m88k.c' also defines the relocations used by
7599 the 88k format *Note Relocations::.
7601 The Intel i960 processor version of coff is implemented in
7602 `coff-i960.c'. This file has the same structure as `coff-m88k.c',
7603 except that it includes `coff/i960.h' rather than `coff-m88k.h'.
7605 3.2.1 Porting to a new version of coff
7606 --------------------------------------
7608 The recommended method is to select from the existing implementations
7609 the version of coff which is most like the one you want to use. For
7610 example, we'll say that i386 coff is the one you select, and that your
7611 coff flavour is called foo. Copy `i386coff.c' to `foocoff.c', copy
7612 `../include/coff/i386.h' to `../include/coff/foo.h', and add the lines
7613 to `targets.c' and `Makefile.in' so that your new back end is used.
7614 Alter the shapes of the structures in `../include/coff/foo.h' so that
7615 they match what you need. You will probably also have to add `#ifdef's
7616 to the code in `coff/internal.h' and `coffcode.h' if your version of
7619 You can verify that your new BFD backend works quite simply by
7620 building `objdump' from the `binutils' directory, and making sure that
7621 its version of what's going on and your host system's idea (assuming it
7622 has the pretty standard coff dump utility, usually called `att-dump' or
7623 just `dump') are the same. Then clean up your code, and send what
7624 you've done to Cygnus. Then your stuff will be in the next release, and
7625 you won't have to keep integrating it.
7627 3.2.2 How the coff backend works
7628 --------------------------------
7633 The Coff backend is split into generic routines that are applicable to
7634 any Coff target and routines that are specific to a particular target.
7635 The target-specific routines are further split into ones which are
7636 basically the same for all Coff targets except that they use the
7637 external symbol format or use different values for certain constants.
7639 The generic routines are in `coffgen.c'. These routines work for
7640 any Coff target. They use some hooks into the target specific code;
7641 the hooks are in a `bfd_coff_backend_data' structure, one of which
7642 exists for each target.
7644 The essentially similar target-specific routines are in
7645 `coffcode.h'. This header file includes executable C code. The
7646 various Coff targets first include the appropriate Coff header file,
7647 make any special defines that are needed, and then include `coffcode.h'.
7649 Some of the Coff targets then also have additional routines in the
7650 target source file itself.
7652 For example, `coff-i960.c' includes `coff/internal.h' and
7653 `coff/i960.h'. It then defines a few constants, such as `I960', and
7654 includes `coffcode.h'. Since the i960 has complex relocation types,
7655 `coff-i960.c' also includes some code to manipulate the i960 relocs.
7656 This code is not in `coffcode.h' because it would not be used by any
7659 3.2.2.2 Bit twiddling
7660 .....................
7662 Each flavour of coff supported in BFD has its own header file
7663 describing the external layout of the structures. There is also an
7664 internal description of the coff layout, in `coff/internal.h'. A major
7665 function of the coff backend is swapping the bytes and twiddling the
7666 bits to translate the external form of the structures into the normal
7667 internal form. This is all performed in the `bfd_swap'_thing_direction
7668 routines. Some elements are different sizes between different versions
7669 of coff; it is the duty of the coff version specific include file to
7670 override the definitions of various packing routines in `coffcode.h'.
7671 E.g., the size of line number entry in coff is sometimes 16 bits, and
7672 sometimes 32 bits. `#define'ing `PUT_LNSZ_LNNO' and `GET_LNSZ_LNNO'
7673 will select the correct one. No doubt, some day someone will find a
7674 version of coff which has a varying field size not catered to at the
7675 moment. To port BFD, that person will have to add more `#defines'.
7676 Three of the bit twiddling routines are exported to `gdb';
7677 `coff_swap_aux_in', `coff_swap_sym_in' and `coff_swap_lineno_in'. `GDB'
7678 reads the symbol table on its own, but uses BFD to fix things up. More
7679 of the bit twiddlers are exported for `gas'; `coff_swap_aux_out',
7680 `coff_swap_sym_out', `coff_swap_lineno_out', `coff_swap_reloc_out',
7681 `coff_swap_filehdr_out', `coff_swap_aouthdr_out',
7682 `coff_swap_scnhdr_out'. `Gas' currently keeps track of all the symbol
7683 table and reloc drudgery itself, thereby saving the internal BFD
7684 overhead, but uses BFD to swap things on the way out, making cross
7685 ports much safer. Doing so also allows BFD (and thus the linker) to
7686 use the same header files as `gas', which makes one avenue to disaster
7689 3.2.2.3 Symbol reading
7690 ......................
7692 The simple canonical form for symbols used by BFD is not rich enough to
7693 keep all the information available in a coff symbol table. The back end
7694 gets around this problem by keeping the original symbol table around,
7695 "behind the scenes".
7697 When a symbol table is requested (through a call to
7698 `bfd_canonicalize_symtab'), a request gets through to
7699 `coff_get_normalized_symtab'. This reads the symbol table from the coff
7700 file and swaps all the structures inside into the internal form. It
7701 also fixes up all the pointers in the table (represented in the file by
7702 offsets from the first symbol in the table) into physical pointers to
7703 elements in the new internal table. This involves some work since the
7704 meanings of fields change depending upon context: a field that is a
7705 pointer to another structure in the symbol table at one moment may be
7706 the size in bytes of a structure at the next. Another pass is made
7707 over the table. All symbols which mark file names (`C_FILE' symbols)
7708 are modified so that the internal string points to the value in the
7709 auxent (the real filename) rather than the normal text associated with
7710 the symbol (`".file"').
7712 At this time the symbol names are moved around. Coff stores all
7713 symbols less than nine characters long physically within the symbol
7714 table; longer strings are kept at the end of the file in the string
7715 table. This pass moves all strings into memory and replaces them with
7716 pointers to the strings.
7718 The symbol table is massaged once again, this time to create the
7719 canonical table used by the BFD application. Each symbol is inspected
7720 in turn, and a decision made (using the `sclass' field) about the
7721 various flags to set in the `asymbol'. *Note Symbols::. The generated
7722 canonical table shares strings with the hidden internal symbol table.
7724 Any linenumbers are read from the coff file too, and attached to the
7725 symbols which own the functions the linenumbers belong to.
7727 3.2.2.4 Symbol writing
7728 ......................
7730 Writing a symbol to a coff file which didn't come from a coff file will
7731 lose any debugging information. The `asymbol' structure remembers the
7732 BFD from which the symbol was taken, and on output the back end makes
7733 sure that the same destination target as source target is present.
7735 When the symbols have come from a coff file then all the debugging
7736 information is preserved.
7738 Symbol tables are provided for writing to the back end in a vector
7739 of pointers to pointers. This allows applications like the linker to
7740 accumulate and output large symbol tables without having to do too much
7743 This function runs through the provided symbol table and patches
7744 each symbol marked as a file place holder (`C_FILE') to point to the
7745 next file place holder in the list. It also marks each `offset' field
7746 in the list with the offset from the first symbol of the current symbol.
7748 Another function of this procedure is to turn the canonical value
7749 form of BFD into the form used by coff. Internally, BFD expects symbol
7750 values to be offsets from a section base; so a symbol physically at
7751 0x120, but in a section starting at 0x100, would have the value 0x20.
7752 Coff expects symbols to contain their final value, so symbols have
7753 their values changed at this point to reflect their sum with their
7754 owning section. This transformation uses the `output_section' field of
7755 the `asymbol''s `asection' *Note Sections::.
7757 * `coff_mangle_symbols'
7758 This routine runs though the provided symbol table and uses the
7759 offsets generated by the previous pass and the pointers generated when
7760 the symbol table was read in to create the structured hierarchy
7761 required by coff. It changes each pointer to a symbol into the index
7762 into the symbol table of the asymbol.
7764 * `coff_write_symbols'
7765 This routine runs through the symbol table and patches up the
7766 symbols from their internal form into the coff way, calls the bit
7767 twiddlers, and writes out the table to the file.
7769 3.2.2.5 `coff_symbol_type'

8109 3.2.2.7 Writing relocations
8110 ...........................
8112 To write relocations, the back end steps though the canonical
8113 relocation table and create an `internal_reloc'. The symbol index to
8114 use is removed from the `offset' field in the symbol table supplied.
8115 The address comes directly from the sum of the section base address and
8116 the relocation offset; the type is dug directly from the howto field.
8117 Then the `internal_reloc' is swapped into the shape of an
8118 `external_reloc' and written out to disk.
8120 3.2.2.8 Reading linenumbers
8121 ...........................
8123 Creating the linenumber table is done by reading in the entire coff
8124 linenumber table, and creating another table for internal use.
8126 A coff linenumber table is structured so that each function is
8127 marked as having a line number of 0. Each line within the function is
8128 an offset from the first line in the function. The base of the line
8129 number information for the table is stored in the symbol associated
8132 Note: The PE format uses line number 0 for a flag indicating a new
8135 The information is copied from the external to the internal table,
8136 and each symbol which marks a function is marked by pointing its...
8138 How does this work ?
8140 3.2.2.9 Reading relocations
8141 ...........................
8143 Coff relocations are easily transformed into the internal BFD form
8146 Reading a coff relocation table is done in the following stages:
8148 * Read the entire coff relocation table into memory.
8150 * Process each relocation in turn; first swap it from the external
8151 to the internal form.
8153 * Turn the symbol referenced in the relocation's symbol index into a
8154 pointer into the canonical symbol table. This table is the same
8155 as the one returned by a call to `bfd_canonicalize_symtab'. The
8156 back end will call that routine and save the result if a
8157 canonicalization hasn't been done.
8159 * The reloc index is turned into a pointer to a howto structure, in
8160 a back end specific way. For instance, the 386 and 960 use the
8161 `r_type' to directly produce an index into a howto table vector;
8162 the 88k subtracts a number from the `r_type' field and creates an
8166 File: bfd.info, Node: elf, Next: mmo, Prev: coff, Up: BFD back ends
8171 BFD support for ELF formats is being worked on. Currently, the best
8172 supported back ends are for sparc and i386 (running svr4 or Solaris 2).
8174 Documentation of the internals of the support code still needs to be
8175 written. The code is changing quickly enough that we haven't bothered
8178 3.3.0.1 `bfd_elf_find_section'
8179 ..............................
8182 struct elf_internal_shdr *bfd_elf_find_section (bfd *abfd, char *name);
8184 Helper functions for GDB to locate the string tables. Since BFD hides
8185 string tables from callers, GDB needs to use an internal hook to find
8186 them. Sun's .stabstr, in particular, isn't even pointed to by the
8187 .stab section, so ordinary mechanisms wouldn't work to find it, even if
8191 File: bfd.info, Node: mmo, Prev: elf, Up: BFD back ends
8196 The mmo object format is used exclusively together with Professor
8197 Donald E. Knuth's educational 64-bit processor MMIX. The simulator
8198 `mmix' which is available at
8199 `http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz'
8200 understands this format. That package also includes a combined
8201 assembler and linker called `mmixal'. The mmo format has no advantages
8202 feature-wise compared to e.g. ELF. It is a simple non-relocatable
8203 object format with no support for archives or debugging information,
8204 except for symbol value information and line numbers (which is not yet
8205 implemented in BFD). See
8206 `http://www-cs-faculty.stanford.edu/~knuth/mmix.html' for more
8207 information about MMIX. The ELF format is used for intermediate object
8208 files in the BFD implementation.
8214 * mmo section mapping::
8217 File: bfd.info, Node: File layout, Next: Symbol-table, Prev: mmo, Up: mmo
8222 The mmo file contents is not partitioned into named sections as with
8223 e.g. ELF. Memory areas is formed by specifying the location of the
8224 data that follows. Only the memory area `0x0000...00' to `0x01ff...ff'
8225 is executable, so it is used for code (and constants) and the area
8226 `0x2000...00' to `0x20ff...ff' is used for writable data. *Note mmo
8229 There is provision for specifying "special data" of 65536 different
8230 types. We use type 80 (decimal), arbitrarily chosen the same as the
8231 ELF `e_machine' number for MMIX, filling it with section information
8232 normally found in ELF objects. *Note mmo section mapping::.
8234 Contents is entered as 32-bit words, xor:ed over previous contents,
8235 always zero-initialized. A word that starts with the byte `0x98' forms
8236 a command called a `lopcode', where the next byte distinguished between
8237 the thirteen lopcodes. The two remaining bytes, called the `Y' and `Z'
8238 fields, or the `YZ' field (a 16-bit big-endian number), are used for
8239 various purposes different for each lopcode. As documented in
8240 `http://www-cs-faculty.stanford.edu/~knuth/mmixal-intro.ps.gz', the
8244 0x98000001. The next word is contents, regardless of whether it
8245 starts with 0x98 or not.
8248 0x9801YYZZ, where `Z' is 1 or 2. This is a location directive,
8249 setting the location for the next data to the next 32-bit word
8250 (for Z = 1) or 64-bit word (for Z = 2), plus Y * 2^56. Normally
8251 `Y' is 0 for the text segment and 2 for the data segment.
8254 0x9802YYZZ. Increase the current location by `YZ' bytes.
8257 0x9803YYZZ, where `Z' is 1 or 2. Store the current location as 64
8258 bits into the location pointed to by the next 32-bit (Z = 1) or
8259 64-bit (Z = 2) word, plus Y * 2^56.
8262 0x9804YYZZ. `YZ' is stored into the current location plus 2 - 4 *
8266 0x980500ZZ. `Z' is 16 or 24. A value `L' derived from the
8267 following 32-bit word are used in a manner similar to `YZ' in
8268 lop_fixr: it is xor:ed into the current location minus 4 * L. The
8269 first byte of the word is 0 or 1. If it is 1, then L = (LOWEST 24
8270 BITS OF WORD) - 2^Z, if 0, then L = (LOWEST 24 BITS OF WORD).
8273 0x9806YYZZ. `Y' is the file number, `Z' is count of 32-bit words.
8274 Set the file number to `Y' and the line counter to 0. The next Z
8275 * 4 bytes contain the file name, padded with zeros if the count is
8276 not a multiple of four. The same `Y' may occur multiple times,
8277 but `Z' must be 0 for all but the first occurrence.
8280 0x9807YYZZ. `YZ' is the line number. Together with lop_file, it
8281 forms the source location for the next 32-bit word. Note that for
8282 each non-lopcode 32-bit word, line numbers are assumed incremented
8286 0x9808YYZZ. `YZ' is the type number. Data until the next lopcode
8287 other than lop_quote forms special data of type `YZ'. *Note mmo
8290 Other types than 80, (or type 80 with a content that does not
8291 parse) is stored in sections named `.MMIX.spec_data.N' where N is
8292 the `YZ'-type. The flags for such a sections say not to allocate
8293 or load the data. The vma is 0. Contents of multiple occurrences
8294 of special data N is concatenated to the data of the previous
8295 lop_spec Ns. The location in data or code at which the lop_spec
8299 0x980901ZZ. The first lopcode in a file. The `Z' field forms the
8300 length of header information in 32-bit words, where the first word
8301 tells the time in seconds since `00:00:00 GMT Jan 1 1970'.
8304 0x980a00ZZ. Z > 32. This lopcode follows after all
8305 content-generating lopcodes in a program. The `Z' field denotes
8306 the value of `rG' at the beginning of the program. The following
8307 256 - Z big-endian 64-bit words are loaded into global registers
8311 0x980b0000. The next-to-last lopcode in a program. Must follow
8312 immediately after the lop_post lopcode and its data. After this
8313 lopcode follows all symbols in a compressed format (*note
8317 0x980cYYZZ. The last lopcode in a program. It must follow the
8318 lop_stab lopcode and its data. The `YZ' field contains the number
8319 of 32-bit words of symbol table information after the preceding
8322 Note that the lopcode "fixups"; `lop_fixr', `lop_fixrx' and
8323 `lop_fixo' are not generated by BFD, but are handled. They are
8324 generated by `mmixal'.
8326 This trivial one-label, one-instruction file:
8330 can be represented this way in mmo:
8332 0x98090101 - lop_pre, one 32-bit word with timestamp.
8334 0x98010002 - lop_loc, text segment, using a 64-bit address.

8357 3.4.2 Symbol table format
8358 -------------------------
8360 From mmixal.w (or really, the generated mmixal.tex) in
8361 `http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz'):
8362 "Symbols are stored and retrieved by means of a `ternary search trie',
8363 following ideas of Bentley and Sedgewick. (See ACM-SIAM Symp. on
8364 Discrete Algorithms `8' (1997), 360-369; R.Sedgewick, `Algorithms in C'
8365 (Reading, Mass. Addison-Wesley, 1998), `15.4'.) Each trie node stores
8366 a character, and there are branches to subtries for the cases where a
8367 given character is less than, equal to, or greater than the character
8368 in the trie. There also is a pointer to a symbol table entry if a
8369 symbol ends at the current node."
8371 So it's a tree encoded as a stream of bytes. The stream of bytes
8372 acts on a single virtual global symbol, adding and removing characters
8373 and signalling complete symbol points. Here, we read the stream and
8374 create symbols at the completion points.
8376 First, there's a control byte `m'. If any of the listed bits in `m'
8377 is nonzero, we execute what stands at the right, in the listed order:
8380 0x40 - Traverse left trie.
8381 (Read a new command byte and recurse.)
8384 0x2f - Read the next byte as a character and store it in the
8385 current character position; increment character position.
8386 Test the bits of `m':
8389 0x80 - The character is 16-bit (so read another byte,
8390 merge into current character.
8393 0xf - We have a complete symbol; parse the type, value
8394 and serial number and do what should be done
8395 with a symbol. The type and length information
8396 is in j = (m & 0xf).
8399 j == 0xf: A register variable. The following
8400 byte tells which register.
8401 j <= 8: An absolute symbol. Read j bytes as the
8402 big-endian number the symbol equals.
8403 A j = 2 with two zero bytes denotes an
8405 j > 8: As with j <= 8, but add (0x20 << 56)
8406 to the value in the following j - 8
8409 Then comes the serial number, as a variant of
8410 uleb128, but better named ubeb128:
8411 Read bytes and shift the previous value left 7
8412 (multiply by 128). Add in the new byte, repeat
8413 until a byte has bit 7 set. The serial number
8414 is the computed value minus 128.
8417 0x20 - Traverse middle trie. (Read a new command byte
8418 and recurse.) Decrement character position.
8421 0x10 - Traverse right trie. (Read a new command byte and
8424 Let's look again at the `lop_stab' for the trivial file (*note File
8427 0x980b0000 - lop_stab for ":Main" = 0, serial 1.
8434 This forms the trivial trie (note that the path between ":" and "M"
8446 016e "n" is the last character in a full symbol, and
8447 with a value represented in one byte.
8449 81 The serial number is 1.

8454 3.4.3 mmo section mapping
8455 -------------------------
8457 The implementation in BFD uses special data type 80 (decimal) to
8458 encapsulate and describe named sections, containing e.g. debug
8459 information. If needed, any datum in the encapsulation will be quoted
8460 using lop_quote. First comes a 32-bit word holding the number of
8461 32-bit words containing the zero-terminated zero-padded segment name.
8462 After the name there's a 32-bit word holding flags describing the
8463 section type. Then comes a 64-bit big-endian word with the section
8464 length (in bytes), then another with the section start address.
8465 Depending on the type of section, the contents might follow,
8466 zero-padded to 32-bit boundary. For a loadable section (such as data
8467 or code), the contents might follow at some later point, not
8468 necessarily immediately, as a lop_loc with the same start address as in
8469 the section description, followed by the contents. This in effect
8470 forms a descriptor that must be emitted before the actual contents.
8471 Sections described this way must not overlap.
8473 For areas that don't have such descriptors, synthetic sections are
8474 formed by BFD. Consecutive contents in the two memory areas
8475 `0x0000...00' to `0x01ff...ff' and `0x2000...00' to `0x20ff...ff' are
8476 entered in sections named `.text' and `.data' respectively. If an area
8477 is not otherwise described, but would together with a neighboring lower
8478 area be less than `0x40000000' bytes long, it is joined with the lower
8479 area and the gap is zero-filled. For other cases, a new section is
8480 formed, named `.MMIX.sec.N'. Here, N is a number, a running count
8481 through the mmo file, starting at 0.
8483 A loadable section specified as:
8485 .section secname,"ax"
8486 TETRA 1,2,3,4,-1,-2009
8489 and linked to address `0x4', is represented by the sequence:
8491 0x98080050 - lop_spec 80
8492 0x00000002 - two 32-bit words for the section name
8494 0x616d6500 - "ame\0"
8495 0x00000033 - flags CODE, READONLY, LOAD, ALLOC
8496 0x00000000 - high 32 bits of section length
8497 0x0000001c - section length is 28 bytes; 6 * 4 + 1 + alignment to 32 bits
8498 0x00000000 - high 32 bits of section address
8499 0x00000004 - section address is 4
8500 0x98010002 - 64 bits with address of following data
8501 0x00000000 - high 32 bits of address
8502 0x00000004 - low 32 bits: data starts at address 4
8509 0x50000000 - 80 as a byte, padded with zeros.
8511 Note that the lop_spec wrapping does not include the section
8512 contents. Compare this to a non-loaded section specified as:
8518 This, when linked to address `0x200000000000001c', is represented by:
8520 0x98080050 - lop_spec 80
8521 0x00000002 - two 32-bit words for the section name
8524 0x00000010 - flag READONLY
8525 0x00000000 - high 32 bits of section length
8526 0x0000000c - section length is 12 bytes; 2 * 4 + 2 + alignment to 32 bits
8527 0x20000000 - high 32 bits of address
8528 0x0000001c - low 32 bits of address 0x200000000000001c
8531 0x26280000 - 38, 40 as bytes, padded with zeros
8533 For the latter example, the section contents must not be loaded in
8534 memory, and is therefore specified as part of the special data. The
8535 address is usually unimportant but might provide information for e.g.
8536 the DWARF 2 debugging format.

8544 Version 1.1, March 2000
8546 Copyright (C) 2000, 2003 Free Software Foundation, Inc.
8547 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
8549 Everyone is permitted to copy and distribute verbatim copies
8550 of this license document, but changing it is not allowed.
8555 The purpose of this License is to make a manual, textbook, or other
8556 written document "free" in the sense of freedom: to assure everyone
8557 the effective freedom to copy and redistribute it, with or without
8558 modifying it, either commercially or noncommercially. Secondarily,
8559 this License preserves for the author and publisher a way to get
8560 credit for their work, while not being considered responsible for
8561 modifications made by others.
8563 This License is a kind of "copyleft", which means that derivative
8564 works of the document must themselves be free in the same sense.
8565 It complements the GNU General Public License, which is a copyleft
8566 license designed for free software.
8568 We have designed this License in order to use it for manuals for
8569 free software, because free software needs free documentation: a
8570 free program should come with manuals providing the same freedoms
8571 that the software does. But this License is not limited to
8572 software manuals; it can be used for any textual work, regardless
8573 of subject matter or whether it is published as a printed book.
8574 We recommend this License principally for works whose purpose is
8575 instruction or reference.
8578 1. APPLICABILITY AND DEFINITIONS
8580 This License applies to any manual or other work that contains a
8581 notice placed by the copyright holder saying it can be distributed
8582 under the terms of this License. The "Document", below, refers to
8583 any such manual or work. Any member of the public is a licensee,
8584 and is addressed as "you."
8586 A "Modified Version" of the Document means any work containing the
8587 Document or a portion of it, either copied verbatim, or with
8588 modifications and/or translated into another language.
8590 A "Secondary Section" is a named appendix or a front-matter
8591 section of the Document that deals exclusively with the
8592 relationship of the publishers or authors of the Document to the
8593 Document's overall subject (or to related matters) and contains
8594 nothing that could fall directly within that overall subject.
8595 (For example, if the Document is in part a textbook of
8596 mathematics, a Secondary Section may not explain any mathematics.)
8597 The relationship could be a matter of historical connection with
8598 the subject or with related matters, or of legal, commercial,
8599 philosophical, ethical or political position regarding them.
8601 The "Invariant Sections" are certain Secondary Sections whose
8602 titles are designated, as being those of Invariant Sections, in
8603 the notice that says that the Document is released under this
8606 The "Cover Texts" are certain short passages of text that are
8607 listed, as Front-Cover Texts or Back-Cover Texts, in the notice
8608 that says that the Document is released under this License.
8610 A "Transparent" copy of the Document means a machine-readable copy,
8611 represented in a format whose specification is available to the
8612 general public, whose contents can be viewed and edited directly
8613 and straightforwardly with generic text editors or (for images
8614 composed of pixels) generic paint programs or (for drawings) some
8615 widely available drawing editor, and that is suitable for input to
8616 text formatters or for automatic translation to a variety of
8617 formats suitable for input to text formatters. A copy made in an
8618 otherwise Transparent file format whose markup has been designed
8619 to thwart or discourage subsequent modification by readers is not
8620 Transparent. A copy that is not "Transparent" is called "Opaque."
8622 Examples of suitable formats for Transparent copies include plain
8623 ASCII without markup, Texinfo input format, LaTeX input format,
8624 SGML or XML using a publicly available DTD, and
8625 standard-conforming simple HTML designed for human modification.
8626 Opaque formats include PostScript, PDF, proprietary formats that
8627 can be read and edited only by proprietary word processors, SGML
8628 or XML for which the DTD and/or processing tools are not generally
8629 available, and the machine-generated HTML produced by some word
8630 processors for output purposes only.
8632 The "Title Page" means, for a printed book, the title page itself,
8633 plus such following pages as are needed to hold, legibly, the
8634 material this License requires to appear in the title page. For
8635 works in formats which do not have any title page as such, "Title
8636 Page" means the text near the most prominent appearance of the
8637 work's title, preceding the beginning of the body of the text.
8641 You may copy and distribute the Document in any medium, either
8642 commercially or noncommercially, provided that this License, the
8643 copyright notices, and the license notice saying this License
8644 applies to the Document are reproduced in all copies, and that you
8645 add no other conditions whatsoever to those of this License. You
8646 may not use technical measures to obstruct or control the reading
8647 or further copying of the copies you make or distribute. However,
8648 you may accept compensation in exchange for copies. If you
8649 distribute a large enough number of copies you must also follow
8650 the conditions in section 3.
8652 You may also lend copies, under the same conditions stated above,
8653 and you may publicly display copies.
8655 3. COPYING IN QUANTITY
8657 If you publish printed copies of the Document numbering more than
8658 100, and the Document's license notice requires Cover Texts, you
8659 must enclose the copies in covers that carry, clearly and legibly,
8660 all these Cover Texts: Front-Cover Texts on the front cover, and
8661 Back-Cover Texts on the back cover. Both covers must also clearly
8662 and legibly identify you as the publisher of these copies. The
8663 front cover must present the full title with all words of the
8664 title equally prominent and visible. You may add other material
8665 on the covers in addition. Copying with changes limited to the
8666 covers, as long as they preserve the title of the Document and
8667 satisfy these conditions, can be treated as verbatim copying in
8670 If the required texts for either cover are too voluminous to fit
8671 legibly, you should put the first ones listed (as many as fit
8672 reasonably) on the actual cover, and continue the rest onto
8675 If you publish or distribute Opaque copies of the Document
8676 numbering more than 100, you must either include a
8677 machine-readable Transparent copy along with each Opaque copy, or
8678 state in or with each Opaque copy a publicly-accessible
8679 computer-network location containing a complete Transparent copy
8680 of the Document, free of added material, which the general
8681 network-using public has access to download anonymously at no
8682 charge using public-standard network protocols. If you use the
8683 latter option, you must take reasonably prudent steps, when you
8684 begin distribution of Opaque copies in quantity, to ensure that
8685 this Transparent copy will remain thus accessible at the stated
8686 location until at least one year after the last time you
8687 distribute an Opaque copy (directly or through your agents or
8688 retailers) of that edition to the public.
8690 It is requested, but not required, that you contact the authors of
8691 the Document well before redistributing any large number of
8692 copies, to give them a chance to provide you with an updated
8693 version of the Document.
8697 You may copy and distribute a Modified Version of the Document
8698 under the conditions of sections 2 and 3 above, provided that you
8699 release the Modified Version under precisely this License, with
8700 the Modified Version filling the role of the Document, thus
8701 licensing distribution and modification of the Modified Version to
8702 whoever possesses a copy of it. In addition, you must do these
8703 things in the Modified Version:
8705 A. Use in the Title Page (and on the covers, if any) a title
8706 distinct from that of the Document, and from those of previous
8707 versions (which should, if there were any, be listed in the
8708 History section of the Document). You may use the same title
8709 as a previous version if the original publisher of that version
8711 B. List on the Title Page, as authors, one or more persons or
8712 entities responsible for authorship of the modifications in the
8713 Modified Version, together with at least five of the principal
8714 authors of the Document (all of its principal authors, if it
8715 has less than five).
8716 C. State on the Title page the name of the publisher of the
8717 Modified Version, as the publisher.
8718 D. Preserve all the copyright notices of the Document.
8719 E. Add an appropriate copyright notice for your modifications
8720 adjacent to the other copyright notices.
8721 F. Include, immediately after the copyright notices, a license
8722 notice giving the public permission to use the Modified Version
8723 under the terms of this License, in the form shown in the
8725 G. Preserve in that license notice the full lists of Invariant
8726 Sections and required Cover Texts given in the Document's
8728 H. Include an unaltered copy of this License.
8729 I. Preserve the section entitled "History", and its title, and add
8730 to it an item stating at least the title, year, new authors, and
8731 publisher of the Modified Version as given on the Title Page.
8732 If there is no section entitled "History" in the Document,
8733 create one stating the title, year, authors, and publisher of
8734 the Document as given on its Title Page, then add an item
8735 describing the Modified Version as stated in the previous
8737 J. Preserve the network location, if any, given in the Document for
8738 public access to a Transparent copy of the Document, and
8739 likewise the network locations given in the Document for
8740 previous versions it was based on. These may be placed in the
8741 "History" section. You may omit a network location for a work
8742 that was published at least four years before the Document
8743 itself, or if the original publisher of the version it refers
8744 to gives permission.
8745 K. In any section entitled "Acknowledgements" or "Dedications",
8746 preserve the section's title, and preserve in the section all the
8747 substance and tone of each of the contributor acknowledgements
8748 and/or dedications given therein.
8749 L. Preserve all the Invariant Sections of the Document,
8750 unaltered in their text and in their titles. Section numbers
8751 or the equivalent are not considered part of the section titles.
8752 M. Delete any section entitled "Endorsements." Such a section
8753 may not be included in the Modified Version.
8754 N. Do not retitle any existing section as "Endorsements" or to
8755 conflict in title with any Invariant Section.
8757 If the Modified Version includes new front-matter sections or
8758 appendices that qualify as Secondary Sections and contain no
8759 material copied from the Document, you may at your option
8760 designate some or all of these sections as invariant. To do this,
8761 add their titles to the list of Invariant Sections in the Modified
8762 Version's license notice. These titles must be distinct from any
8763 other section titles.
8765 You may add a section entitled "Endorsements", provided it contains
8766 nothing but endorsements of your Modified Version by various
8767 parties-for example, statements of peer review or that the text has
8768 been approved by an organization as the authoritative definition
8771 You may add a passage of up to five words as a Front-Cover Text,
8772 and a passage of up to 25 words as a Back-Cover Text, to the end
8773 of the list of Cover Texts in the Modified Version. Only one
8774 passage of Front-Cover Text and one of Back-Cover Text may be
8775 added by (or through arrangements made by) any one entity. If the
8776 Document already includes a cover text for the same cover,
8777 previously added by you or by arrangement made by the same entity
8778 you are acting on behalf of, you may not add another; but you may
8779 replace the old one, on explicit permission from the previous
8780 publisher that added the old one.
8782 The author(s) and publisher(s) of the Document do not by this
8783 License give permission to use their names for publicity for or to
8784 assert or imply endorsement of any Modified Version.
8786 5. COMBINING DOCUMENTS
8788 You may combine the Document with other documents released under
8789 this License, under the terms defined in section 4 above for
8790 modified versions, provided that you include in the combination
8791 all of the Invariant Sections of all of the original documents,
8792 unmodified, and list them all as Invariant Sections of your
8793 combined work in its license notice.
8795 The combined work need only contain one copy of this License, and
8796 multiple identical Invariant Sections may be replaced with a single
8797 copy. If there are multiple Invariant Sections with the same name
8798 but different contents, make the title of each such section unique
8799 by adding at the end of it, in parentheses, the name of the
8800 original author or publisher of that section if known, or else a
8801 unique number. Make the same adjustment to the section titles in
8802 the list of Invariant Sections in the license notice of the
8805 In the combination, you must combine any sections entitled
8806 "History" in the various original documents, forming one section
8807 entitled "History"; likewise combine any sections entitled
8808 "Acknowledgements", and any sections entitled "Dedications." You
8809 must delete all sections entitled "Endorsements."
8811 6. COLLECTIONS OF DOCUMENTS
8813 You may make a collection consisting of the Document and other
8814 documents released under this License, and replace the individual
8815 copies of this License in the various documents with a single copy
8816 that is included in the collection, provided that you follow the
8817 rules of this License for verbatim copying of each of the
8818 documents in all other respects.
8820 You may extract a single document from such a collection, and
8821 distribute it individually under this License, provided you insert
8822 a copy of this License into the extracted document, and follow
8823 this License in all other respects regarding verbatim copying of
8826 7. AGGREGATION WITH INDEPENDENT WORKS
8828 A compilation of the Document or its derivatives with other
8829 separate and independent documents or works, in or on a volume of
8830 a storage or distribution medium, does not as a whole count as a
8831 Modified Version of the Document, provided no compilation
8832 copyright is claimed for the compilation. Such a compilation is
8833 called an "aggregate", and this License does not apply to the
8834 other self-contained works thus compiled with the Document, on
8835 account of their being thus compiled, if they are not themselves
8836 derivative works of the Document.
8838 If the Cover Text requirement of section 3 is applicable to these
8839 copies of the Document, then if the Document is less than one
8840 quarter of the entire aggregate, the Document's Cover Texts may be
8841 placed on covers that surround only the Document within the
8842 aggregate. Otherwise they must appear on covers around the whole
8847 Translation is considered a kind of modification, so you may
8848 distribute translations of the Document under the terms of section
8849 4. Replacing Invariant Sections with translations requires special
8850 permission from their copyright holders, but you may include
8851 translations of some or all Invariant Sections in addition to the
8852 original versions of these Invariant Sections. You may include a
8853 translation of this License provided that you also include the
8854 original English version of this License. In case of a
8855 disagreement between the translation and the original English
8856 version of this License, the original English version will prevail.
8860 You may not copy, modify, sublicense, or distribute the Document
8861 except as expressly provided for under this License. Any other
8862 attempt to copy, modify, sublicense or distribute the Document is
8863 void, and will automatically terminate your rights under this
8864 License. However, parties who have received copies, or rights,
8865 from you under this License will not have their licenses
8866 terminated so long as such parties remain in full compliance.
8868 10. FUTURE REVISIONS OF THIS LICENSE
8870 The Free Software Foundation may publish new, revised versions of
8871 the GNU Free Documentation License from time to time. Such new
8872 versions will be similar in spirit to the present version, but may
8873 differ in detail to address new problems or concerns. See
8874 http://www.gnu.org/copyleft/.
8876 Each version of the License is given a distinguishing version
8877 number. If the Document specifies that a particular numbered
8878 version of this License "or any later version" applies to it, you
8879 have the option of following the terms and conditions either of
8880 that specified version or of any later version that has been
8881 published (not as a draft) by the Free Software Foundation. If
8882 the Document does not specify a version number of this License,
8883 you may choose any version ever published (not as a draft) by the
8884 Free Software Foundation.
8887 ADDENDUM: How to use this License for your documents
8888 ====================================================
8890 To use this License in a document you have written, include a copy of
8891 the License in the document and put the following copyright and license
8892 notices just after the title page:
