471 Introduction
48**************
49
50BFD is a package which allows applications to use the same routines to
51operate on object files whatever the object file format.  A new object
52file format can be supported simply by creating a new BFD back end and
53adding it to the library.
54
55   BFD is split into two parts: the front end, and the back ends (one
56for each object file format).
57   * The front end of BFD provides the interface to the user. It manages
58     memory and various canonical data structures. The front end also
59     decides which back end to use and when to call back end routines.
60
61   * The back ends provide BFD its view of the real world. Each back
62     end provides a set of calls which the BFD front end can use to
63     maintain its canonical form. The back ends also may keep around
64     information for their own use, for greater efficiency.

751.1 History
76===========
77
78One spur behind BFD was the desire, on the part of the GNU 960 team at
79Intel Oregon, for interoperability of applications on their COFF and
80b.out file formats.  Cygnus was providing GNU support for the team, and
81was contracted to provide the required functionality.
82
83   The name came from a conversation David Wallace was having with
84Richard Stallman about the library: RMS said that it would be quite
85hard--David said "BFD".  Stallman was right, but the name stuck.
86
87   At the same time, Ready Systems wanted much the same thing, but for
88different object file formats: IEEE-695, Oasys, Srecords, a.out and 68k
89coff.
90
91   BFD was first implemented by members of Cygnus Support; Steve
92Chamberlain (`sac@cygnus.com'), John Gilmore (`gnu@cygnus.com'), K.
93Richard Pixley (`rich@cygnus.com') and David Henkel-Wallace
94(`gumby@cygnus.com').

991.2 How To Use BFD
100==================
101
102To use the library, include `bfd.h' and link with `libbfd.a'.
103
104   BFD provides a common interface to the parts of an object file for a
105calling application.
106
107   When an application successfully opens a target file (object,
108archive, or whatever), a pointer to an internal structure is returned.
109This pointer points to a structure called `bfd', described in `bfd.h'.
110Our convention is to call this pointer a BFD, and instances of it
111within code `abfd'.  All operations on the target object file are
112applied as methods to the BFD.  The mapping is defined within `bfd.h'
113in a set of macros, all beginning with `bfd_' to reduce namespace
114pollution.
115
116   For example, this sequence does what you would probably expect:
117return the number of sections in an object file attached to a BFD
118`abfd'.
119
120     #include "bfd.h"
121
122     unsigned int number_of_sections (abfd)
123     bfd *abfd;
124     {
125       return bfd_count_sections (abfd);
126     }
127
128   The abstraction used within BFD is that an object file has:
129
130   * a header,
131
132   * a number of sections containing raw data (*note Sections::),
133
134   * a set of relocations (*note Relocations::), and
135
136   * some symbol information (*note Symbols::).
137   Also, BFDs opened for archives have the additional attribute of an
138index and contain subordinate BFDs. This approach is fine for a.out and
139coff, but loses efficiency when applied to formats such as S-records and
140IEEE-695.

144
1451.3 What BFD Version 2 Can Do
146=============================
147
148When an object file is opened, BFD subroutines automatically determine
149the format of the input object file.  They then build a descriptor in
150memory with pointers to routines that will be used to access elements of
151the object file's data structures.
152
153   As different information from the object files is required, BFD
154reads from different sections of the file and processes them.  For
155example, a very common operation for the linker is processing symbol
156tables.  Each BFD back end provides a routine for converting between
157the object file's representation of symbols and an internal canonical
158format. When the linker asks for the symbol table of an object file, it
159calls through a memory pointer to the routine from the relevant BFD
160back end which reads and converts the table into a canonical form.  The
161linker then operates upon the canonical form. When the link is finished
162and the linker writes the output file's symbol table, another BFD back
163end routine is called to take the newly created symbol table and
164convert it into the chosen output format.

173
1741.3.1 Information Loss
175----------------------
176
177_Information can be lost during output._ The output formats supported
178by BFD do not provide identical facilities, and information which can
179be described in one form has nowhere to go in another format. One
180example of this is alignment information in `b.out'. There is nowhere
181in an `a.out' format file to store alignment information on the
182contained data, so when a file is linked from `b.out' and an `a.out'
183image is produced, alignment information will not propagate to the
184output file. (The linker will still use the alignment information
185internally, so the link is performed correctly).
186
187   Another example is COFF section names. COFF files may contain an
188unlimited number of sections, each one with a textual section name. If
189the target of the link is a format which does not have many sections
190(e.g., `a.out') or has sections without names (e.g., the Oasys format),
191the link cannot be done simply. You can circumvent this problem by
192describing the desired input-to-output section mapping with the linker
193command language.
194
195   _Information can be lost during canonicalization._ The BFD internal
196canonical form of the external formats is not exhaustive; there are
197structures in input formats for which there is no direct representation
198internally.  This means that the BFD back ends cannot maintain all
199possible data richness through the transformation between external to
200internal and back to external formats.
201
202   This limitation is only a problem when an application reads one
203format and writes another.  Each BFD back end is responsible for
204maintaining as much data as possible, and the internal BFD canonical
205form has structures which are opaque to the BFD core, and exported only
206to the back ends. When a file is read in one format, the canonical form
207is generated for BFD and the application. At the same time, the back
208end saves away any information which may otherwise be lost. If the data
209is then written back in the same format, the back end routine will be
210able to use the canonical form provided by the BFD core as well as the
211information it prepared earlier.  Since there is a great deal of
212commonality between back ends, there is no information lost when
213linking or copying big endian COFF to little endian COFF, or `a.out' to
214`b.out'.  When a mixture of formats is linked, the information is only
215lost from the files whose format differs from the destination.

219
2201.3.2 The BFD canonical object-file format
221------------------------------------------
222
223The greatest potential for loss of information occurs when there is the
224least overlap between the information provided by the source format,
225that stored by the canonical format, and that needed by the destination
226format. A brief description of the canonical form may help you
227understand which kinds of data you can count on preserving across
228conversions.  
229
230_files_
231     Information stored on a per-file basis includes target machine
232     architecture, particular implementation format type, a demand
233     pageable bit, and a write protected bit.  Information like Unix
234     magic numbers is not stored here--only the magic numbers' meaning,
235     so a `ZMAGIC' file would have both the demand pageable bit and the
236     write protected text bit set.  The byte order of the target is
237     stored on a per-file basis, so that big- and little-endian object
238     files may be used with one another.
239
240_sections_
241     Each section in the input file contains the name of the section,
242     the section's original address in the object file, size and
243     alignment information, various flags, and pointers into other BFD
244     data structures.
245
246_symbols_
247     Each symbol contains a pointer to the information for the object
248     file which originally defined it, its name, its value, and various
249     flag bits.  When a BFD back end reads in a symbol table, it
250     relocates all symbols to make them relative to the base of the
251     section where they were defined.  Doing this ensures that each
252     symbol points to its containing section.  Each symbol also has a
253     varying amount of hidden private data for the BFD back end.  Since
254     the symbol points to the original file, the private data format
255     for that symbol is accessible.  `ld' can operate on a collection
256     of symbols of wildly different formats without problems.
257
258     Normal global and simple local symbols are maintained on output,
259     so an output file (no matter its format) will retain symbols
260     pointing to functions and to global, static, and common variables.
261     Some symbol information is not worth retaining; in `a.out', type
262     information is stored in the symbol table as long symbol names.
263     This information would be useless to most COFF debuggers; the
264     linker has command line switches to allow users to throw it away.
265
266     There is one word of type information within the symbol, so if the
267     format supports symbol type information within symbols (for
268     example, COFF, IEEE, Oasys) and the type is simple enough to fit
269     within one word (nearly everything but aggregates), the
270     information will be preserved.
271
272_relocation level_
273     Each canonical BFD relocation record contains a pointer to the
274     symbol to relocate to, the offset of the data to relocate, the
275     section the data is in, and a pointer to a relocation type
276     descriptor. Relocation is performed by passing messages through
277     the relocation type descriptor and the symbol pointer. Therefore,
278     relocations can be performed on output data using a relocation
279     method that is only available in one of the input formats. For
280     instance, Oasys provides a byte relocation format.  A relocation
281     record requesting this relocation type would point indirectly to a
282     routine to perform this, so the relocation may be performed on a
283     byte being written to a 68k COFF file, even though 68k COFF has no
284     such relocation type.
285
286_line numbers_
287     Object formats can contain, for debugging purposes, some form of
288     mapping between symbols, source line numbers, and addresses in the
289     output file.  These addresses have to be relocated along with the
290     symbol information.  Each symbol with an associated list of line
291     number records points to the first record of the list.  The head
292     of a line number list consists of a pointer to the symbol, which
293     allows finding out the address of the function whose line number
294     is being described. The rest of the list is made up of pairs:
295     offsets into the section and line numbers. Any format which can
296     simply derive this information can pass it successfully between
297     formats (COFF, IEEE and Oasys).

5912.2 Error reporting
592===================
593
594Most BFD functions return nonzero on success (check their individual
595documentation for precise semantics).  On an error, they call
596`bfd_set_error' to set an error condition that callers can check by
597calling `bfd_get_error'.  If that returns `bfd_error_system_call', then
598check `errno'.
599
600   The easiest way to report a BFD error to the user is to use
601`bfd_perror'.
602
6032.2.1 Type `bfd_error_type'
604---------------------------
605
606The values returned by `bfd_get_error' are defined by the enumerated
607type `bfd_error_type'.
608
609
610     typedef enum bfd_error
611     {
612       bfd_error_no_error = 0,
613       bfd_error_system_call,
614       bfd_error_invalid_target,
615       bfd_error_wrong_format,
616       bfd_error_wrong_object_format,
617       bfd_error_invalid_operation,
618       bfd_error_no_memory,
619       bfd_error_no_symbols,
620       bfd_error_no_armap,
621       bfd_error_no_more_archived_files,

630       bfd_error_file_too_big,
631       bfd_error_on_input,
632       bfd_error_invalid_error_code
633     }
634     bfd_error_type;
635   
6362.2.1.1 `bfd_get_error'
637.......................
638
639*Synopsis*
640     bfd_error_type bfd_get_error (void);
641   *Description*
642Return the current BFD error condition.
643
6442.2.1.2 `bfd_set_error'
645.......................
646
647*Synopsis*
648     void bfd_set_error (bfd_error_type error_tag, ...);
649   *Description*
650Set the BFD error condition to be ERROR_TAG.  If ERROR_TAG is
651bfd_error_on_input, then this function takes two more parameters, the
652input bfd where the error occurred, and the bfd_error_type error.
653
6542.2.1.3 `bfd_errmsg'
655....................
656
657*Synopsis*
658     const char *bfd_errmsg (bfd_error_type error_tag);
659   *Description*
660Return a string describing the error ERROR_TAG, or the system error if
661ERROR_TAG is `bfd_error_system_call'.
662
6632.2.1.4 `bfd_perror'
664....................
665
666*Synopsis*
667     void bfd_perror (const char *message);
668   *Description*
669Print to the standard error stream a string describing the last BFD
670error that occurred, or the last system error if the last BFD error was
671a system call failure.  If MESSAGE is non-NULL and non-empty, the error
672string printed is preceded by MESSAGE, a colon, and a space.  It is
673followed by a newline.
674
6752.2.2 BFD error handler
676-----------------------
677
678Some BFD functions want to print messages describing the problem.  They
679call a BFD error handler function.  This function may be overridden by
680the program.
681
682   The BFD error handler acts like printf.
683
684
685     typedef void (*bfd_error_handler_type) (const char *, ...);
686   
6872.2.2.1 `bfd_set_error_handler'

689
690*Synopsis*
691     bfd_error_handler_type bfd_set_error_handler (bfd_error_handler_type);
692   *Description*
693Set the BFD error handler function.  Returns the previous function.
694
6952.2.2.2 `bfd_set_error_program_name'
696....................................
697
698*Synopsis*
699     void bfd_set_error_program_name (const char *);
700   *Description*
701Set the program name to use when printing a BFD error.  This is printed
702before the error message followed by a colon and space.  The string
703must not be changed after it is passed to this function.
704
7052.2.2.3 `bfd_get_error_handler'
706...............................
707
708*Synopsis*
709     bfd_error_handler_type bfd_get_error_handler (void);
710   *Description*
711Return the BFD error handler function.

7162.3.1 Miscellaneous functions
717-----------------------------
718
7192.3.1.1 `bfd_get_reloc_upper_bound'
720...................................
721
722*Synopsis*
723     long bfd_get_reloc_upper_bound (bfd *abfd, asection *sect);
724   *Description*
725Return the number of bytes required to store the relocation information
726associated with section SECT attached to bfd ABFD.  If an error occurs,
727return -1.
728
7292.3.1.2 `bfd_canonicalize_reloc'
730................................
731
732*Synopsis*
733     long bfd_canonicalize_reloc
734        (bfd *abfd, asection *sec, arelent **loc, asymbol **syms);
735   *Description*
736Call the back end associated with the open BFD ABFD and translate the
737external form of the relocation information attached to SEC into the
738internal canonical form.  Place the table into memory at LOC, which has
739been preallocated, usually by a call to `bfd_get_reloc_upper_bound'.
740Returns the number of relocs, or -1 on error.
741
742   The SYMS table is also needed for horrible internal magic reasons.
743
7442.3.1.3 `bfd_set_reloc'
745.......................
746
747*Synopsis*
748     void bfd_set_reloc
749        (bfd *abfd, asection *sec, arelent **rel, unsigned int count);
750   *Description*
751Set the relocation pointer and count within section SEC to the values
752REL and COUNT.  The argument ABFD is ignored.
753
7542.3.1.4 `bfd_set_file_flags'
755............................
756
757*Synopsis*
758     bfd_boolean bfd_set_file_flags (bfd *abfd, flagword flags);
759   *Description*
760Set the flag word in the BFD ABFD to the value FLAGS.
761
762   Possible errors are:
763   * `bfd_error_wrong_format' - The target bfd was not of object format.
764
765   * `bfd_error_invalid_operation' - The target bfd was open for
766     reading.
767
768   * `bfd_error_invalid_operation' - The flag word contained a bit
769     which was not applicable to the type of file.  E.g., an attempt
770     was made to set the `D_PAGED' bit on a BFD format which does not
771     support demand paging.
772
7732.3.1.5 `bfd_get_arch_size'
774...........................
775
776*Synopsis*
777     int bfd_get_arch_size (bfd *abfd);
778   *Description*
779Returns the architecture address size, in bits, as determined by the
780object file's format.  For ELF, this information is included in the
781header.
782
783   *Returns*
784Returns the arch size in bits if known, `-1' otherwise.
785
7862.3.1.6 `bfd_get_sign_extend_vma'
787.................................
788
789*Synopsis*
790     int bfd_get_sign_extend_vma (bfd *abfd);
791   *Description*
792Indicates if the target architecture "naturally" sign extends an
793address.  Some architectures implicitly sign extend address values when
794they are converted to types larger than the size of an address.  For
795instance, bfd_get_start_address() will return an address sign extended
796to fill a bfd_vma when this is the case.
797
798   *Returns*
799Returns `1' if the target architecture is known to sign extend
800addresses, `0' if the target architecture is known to not sign extend
801addresses, and `-1' otherwise.
802
8032.3.1.7 `bfd_set_start_address'
804...............................
805
806*Synopsis*
807     bfd_boolean bfd_set_start_address (bfd *abfd, bfd_vma vma);
808   *Description*

815.........................
816
817*Synopsis*
818     unsigned int bfd_get_gp_size (bfd *abfd);
819   *Description*
820Return the maximum size of objects to be optimized using the GP
821register under MIPS ECOFF.  This is typically set by the `-G' argument
822to the compiler, assembler or linker.
823
8242.3.1.9 `bfd_set_gp_size'
825.........................
826
827*Synopsis*
828     void bfd_set_gp_size (bfd *abfd, unsigned int i);
829   *Description*
830Set the maximum size of objects to be optimized using the GP register
831under ECOFF or MIPS ELF.  This is typically set by the `-G' argument to
832the compiler, assembler or linker.
833
8342.3.1.10 `bfd_scan_vma'
835.......................
836
837*Synopsis*
838     bfd_vma bfd_scan_vma (const char *string, const char **end, int base);
839   *Description*
840Convert, like `strtoul', a numerical expression STRING into a `bfd_vma'
841integer, and return that integer.  (Though without as many bells and
842whistles as `strtoul'.)  The expression is assumed to be unsigned
843(i.e., positive).  If given a BASE, it is used as the base for
844conversion.  A base of 0 causes the function to interpret the string in
845hex if a leading "0x" or "0X" is found, otherwise in octal if a leading
846zero is found, otherwise in decimal.
847
848   If the value would overflow, the maximum `bfd_vma' value is returned.
849
8502.3.1.11 `bfd_copy_private_header_data'
851.......................................
852
853*Synopsis*
854     bfd_boolean bfd_copy_private_header_data (bfd *ibfd, bfd *obfd);
855   *Description*
856Copy private BFD header information from the BFD IBFD to the the BFD
857OBFD.  This copies information that may require sections to exist, but
858does not require symbol tables.  Return `true' on success, `false' on
859error.  Possible error returns are:

1038   *Description*
1039When testing an object for compatibility with a particular target
1040back-end, the back-end object_p function needs to set up certain fields
1041in the bfd on successfully recognizing the object.  This typically
1042happens in a piecemeal fashion, with failures possible at many points.
1043On failure, the bfd is supposed to be restored to its initial state,
1044which is virtually impossible.  However, restoring a subset of the bfd
1045state works in practice.  This function stores the subset and
1046reinitializes the bfd.

1167   *Description*
1168Return the file size (as read from file system) for the file associated
1169with BFD ABFD.
1170
1171   The initial motivation for, and use of, this routine is not so we
1172can get the exact size of the object the BFD applies to, since that
1173might not be generally possible (archive members for example).  It
1174would be ideal if someone could eventually modify it so that such
1175results were guaranteed.
1176
1177   Instead, we want to ask questions like "is this NNN byte sized
1178object I'm about to try read from file offset YYY reasonable?"  As as
1179example of where we might do this, some object formats use string
1180tables for which the first `sizeof (long)' bytes of the table contain
1181the size of the table itself, including the size bytes.  If an
1182application tries to read what it thinks is one of these string tables,
1183without some way to validate the size, and for some reason the size is
1184wrong (byte swapping error, wrong location for the string table, etc.),
1185the only clue is likely to be a read error when it tries to read the
1186table, or a "virtual memory exhausted" error when it tries to allocate
118715 bazillon bytes of space for the 15 bazillon byte table it is about
1188to read.  This function at least allows us to answer the question, "is
1189the size reasonable?".

12212.4 Memory Usage
1222================
1223
1224BFD keeps all of its internal structures in obstacks. There is one
1225obstack per open BFD file, into which the current state is stored. When
1226a BFD is closed, the obstack is deleted, and so everything which has
1227been allocated by BFD for the closing file is thrown away.
1228
1229   BFD does not free anything created by an application, but pointers
1230into `bfd' structures become invalid on a `bfd_close'; for example,
1231after a `bfd_close' the vector passed to `bfd_canonicalize_symtab' is
1232still around, since it has been allocated by the application, but the
1233data that it pointed to are lost.
1234
1235   The general rule is to not close a BFD until all operations dependent
1236upon data from the BFD have been completed, or all the data from within
1237the file has been copied. To help with the management of memory, there
1238is a function (`bfd_alloc_size') which returns the number of bytes in
1239obstacks associated with the supplied BFD. This could be used to select
1240the greediest open BFD, close it to reclaim the memory, perform some
1241operation and reopen the BFD again, to get a fresh copy of the data
1242structures.

12672.6 Sections
1268============
1269
1270The raw data contained within a BFD is maintained through the section
1271abstraction.  A single BFD may have any number of sections.  It keeps
1272hold of them by pointing to the first; each one points to the next in
1273the list.
1274
1275   Sections are supported in BFD in `section.c'.

1286
12872.6.1 Section input
1288-------------------
1289
1290When a BFD is opened for reading, the section structures are created
1291and attached to the BFD.
1292
1293   Each section has a name which describes the section in the outside
1294world--for example, `a.out' would contain at least three sections,
1295called `.text', `.data' and `.bss'.
1296
1297   Names need not be unique; for example a COFF file may have several
1298sections named `.data'.
1299
1300   Sometimes a BFD will contain more than the "natural" number of
1301sections. A back end may attach other sections containing constructor
1302data, or an application may add a section (using `bfd_make_section') to
1303the sections attached to an already open BFD. For example, the linker
1304creates an extra section `COMMON' for each input file's BFD to hold
1305information about common storage.
1306
1307   The raw data is not necessarily read in when the section descriptor
1308is created. Some targets may leave the data in place until a
1309`bfd_get_section_contents' call is made. Other back ends may read in
1310all the data at once.  For example, an S-record file has to be read
1311once to determine the size of the data. An IEEE-695 file doesn't
1312contain raw data in sections, but data and relocation expressions
1313intermixed, so the data area has to be parsed to get out the data and
1314relocations.

13192.6.2 Section output
1320--------------------
1321
1322To write a new object style BFD, the various sections to be written
1323have to be created. They are attached to the BFD in the same way as
1324input sections; data is written to the sections using
1325`bfd_set_section_contents'.
1326
1327   Any program that creates or combines sections (e.g., the assembler
1328and linker) must use the `asection' fields `output_section' and
1329`output_offset' to indicate the file sections to which each section
1330must be written.  (If the section is being created from scratch,
1331`output_section' should probably point to the section itself and
1332`output_offset' should probably be zero.)
1333
1334   The data to be written comes from input sections attached (via
1335`output_section' pointers) to the output sections.  The output section
1336structure can be considered a filter for the input section: the output
1337section determines the vma of the output data and the name, but the
1338input section determines the offset into the output section of the data
1339to be written.
1340
1341   E.g., to create a section "O", starting at 0x100, 0x123 long,
1342containing two subsections, "A" at offset 0x0 (i.e., at vma 0x100) and
1343"B" at offset 0x20 (i.e., at vma 0x120) the `asection' structures would
1344look like:
1345
1346        section name          "A"
1347          output_offset   0x00
1348          size            0x20
1349          output_section ----------->  section name    "O"
1350                                  |    vma             0x100
1351        section name          "B" |    size            0x123
1352          output_offset   0x20    |
1353          size            0x103   |
1354          output_section  --------|
1355
13562.6.3 Link orders
1357-----------------

1359The data within a section is stored in a "link_order".  These are much
1360like the fixups in `gas'.  The link_order abstraction allows a section
1361to grow and shrink within itself.
1362
1363   A link_order knows how big it is, and which is the next link_order
1364and where the raw data for it is; it also points to a list of
1365relocations which apply to it.
1366
1367   The link_order is used by the linker to perform relaxing on final
1368code.  The compiler creates code which is as big as necessary to make
1369it work without relaxing, and the user can select whether to relax.
1370Sometimes relaxing takes a lot of time.  The linker runs around the
1371relocations to see if any are attached to data which can be shrunk, if
1372so it does it on a link_order by link_order basis.

1938................................
1939
1940*Synopsis*
1941     void bfd_section_list_clear (bfd *);
1942   *Description*
1943Clears the section list, and also resets the section count and hash
1944table entries.
1945
19462.6.5.2 `bfd_get_section_by_name'
1947.................................
1948
1949*Synopsis*
1950     asection *bfd_get_section_by_name (bfd *abfd, const char *name);
1951   *Description*
1952Run through ABFD and return the one of the `asection's whose name
1953matches NAME, otherwise `NULL'.  *Note Sections::, for more information.
1954
1955   This should only be used in special cases; the normal way to process
1956all sections of a given name is to use `bfd_map_over_sections' and
1957`strcmp' on the name (or better yet, base it on the section flags or
1958something else) for each section.

1969   *Description*
1970Call the provided function FUNC for each section attached to the BFD
1971ABFD whose name matches NAME, passing OBJ as an argument. The function
1972will be called as if by
1973
1974            func (abfd, the_section, obj);
1975
1976   It returns the first section for which FUNC returns true, otherwise

1985   *Description*
1986Invent a section name that is unique in ABFD by tacking a dot and a
1987digit suffix onto the original TEMPLAT.  If COUNT is non-NULL, then it
1988specifies the first number tried as a suffix to generate a unique name.
1989The value pointed to by COUNT will be incremented in this case.

1996   *Description*
1997Create a new empty section called NAME and attach it to the end of the
1998chain of sections for the BFD ABFD. An attempt to create a section with
1999a name which is already in use returns its pointer without changing the
2000section chain.
2001
2002   It has the funny name since this is the way it used to be before it
2003was rewritten....
2004
2005   Possible errors are:
2006   * `bfd_error_invalid_operation' - If output has already started for

2104
2105            func (abfd, the_section, obj);
2106
2107   This is the preferred method for iterating over sections; an

2154starting in memory at DATA. The data is written to the output section
2155starting at offset OFFSET for COUNT octets.
2156
2157   Normally `TRUE' is returned, else `FALSE'. Possible error returns
2158are:
2159   * `bfd_error_no_contents' - The output section does not have the
2160     `SEC_HAS_CONTENTS' attribute, so nothing can be written to it.

22302.7 Symbols
2231===========
2232
2233BFD tries to maintain as much symbol information as it can when it
2234moves information from file to file. BFD passes information to
2235applications though the `asymbol' structure. When the application
2236requests the symbol table, BFD reads the table in the native form and
2237translates parts of it into the internal format. To maintain more than
2238the information passed to applications, some targets keep some
2239information "behind the scenes" in a structure only the particular back
2240end knows about. For example, the coff back end keeps the original
2241symbol table structure as well as the canonical structure when a BFD is
2242read in. On output, the coff back end can reconstruct the output symbol
2243table so that no information is lost, even information unique to coff
2244which BFD doesn't know or understand. If a coff symbol table were read,
2245but were written through an a.out back end, all the coff specific
2246information would be lost. The symbol table of a BFD is not necessarily
2247read in until a canonicalize request is made. Then the BFD back end
2248fills in a table provided by the application with pointers to the
2249canonical information.  To output symbols, the application provides BFD
2250with a table of pointers to pointers to `asymbol's. This allows
2251applications like the linker to output a symbol as it was read, since
2252the "behind the scenes" information will be still available.

22652.7.1 Reading symbols
2266---------------------
2267
2268There are two stages to reading a symbol table from a BFD: allocating
2269storage, and the actual reading process. This is an excerpt from an
2270application which reads the symbol table:
2271
2272              long storage_needed;
2273              asymbol **symbol_table;
2274              long number_of_symbols;
2275              long i;
2276
2277              storage_needed = bfd_get_symtab_upper_bound (abfd);
2278
2279              if (storage_needed < 0)
2280                FAIL
2281
2282              if (storage_needed == 0)
2283                return;
2284
2285              symbol_table = xmalloc (storage_needed);
2286                ...
2287              number_of_symbols =
2288                 bfd_canonicalize_symtab (abfd, symbol_table);
2289
2290              if (number_of_symbols < 0)
2291                FAIL
2292
2293              for (i = 0; i < number_of_symbols; i++)
2294                process_symbol (symbol_table[i]);
2295
2296   All storage for the symbols themselves is in an objalloc connected
2297to the BFD; it is freed when the BFD is closed.

23022.7.2 Writing symbols
2303---------------------
2304
2305Writing of a symbol table is automatic when a BFD open for writing is
2306closed. The application attaches a vector of pointers to pointers to
2307symbols to the BFD being written, and fills in the symbol count. The
2308close and cleanup code reads through the table provided and performs
2309all the necessary operations. The BFD output code must always be
2310provided with an "owned" symbol: one which has come from another BFD,
2311or one which has been created using `bfd_make_empty_symbol'.  Here is an
2312example showing the creation of a symbol table with only one element:
2313
2314            #include "bfd.h"
2315            int main (void)
2316            {
2317              bfd *abfd;
2318              asymbol *ptrs[2];
2319              asymbol *new;
2320
2321              abfd = bfd_openw ("foo","a.out-sunos-big");
2322              bfd_set_format (abfd, bfd_object);
2323              new = bfd_make_empty_symbol (abfd);
2324              new->name = "dummy_symbol";
2325              new->section = bfd_make_section_old_way (abfd, ".text");
2326              new->flags = BSF_GLOBAL;
2327              new->value = 0x12345;
2328
2329              ptrs[0] = new;
2330              ptrs[1] = 0;
2331
2332              bfd_set_symtab (abfd, ptrs, 1);
2333              bfd_close (abfd);
2334              return 0;
2335            }
2336
2337            ./makesym
2338            nm foo
2339            00012345 A dummy_symbol
2340
2341   Many formats cannot represent arbitrary symbol information; for
2342instance, the `a.out' object format does not allow an arbitrary number
2343of sections. A symbol pointing to a section which is not one  of
2344`.text', `.data' or `.bss' cannot be described.

2348
23492.7.3 Mini Symbols
2350------------------
2351
2352Mini symbols provide read-only access to the symbol table.  They use
2353less memory space, but require more time to access.  They can be useful
2354for tools like nm or objdump, which may have to handle symbol tables of
2355extremely large executables.
2356
2357   The `bfd_read_minisymbols' function will read the symbols into
2358memory in an internal form.  It will return a `void *' pointer to a
2359block of memory, a symbol count, and the size of each symbol.  The
2360pointer is allocated using `malloc', and should be freed by the caller

2363   The function `bfd_minisymbol_to_symbol' will take a pointer to a
2364minisymbol, and a pointer to a structure returned by
2365`bfd_make_empty_symbol', and return a `asymbol' structure.  The return
2366value may or may not be the same as the value from
2367`bfd_make_empty_symbol' which was passed in.

26822.8 Archives
2683============
2684
2685*Description*
2686An archive (or library) is just another BFD.  It has a symbol table,
2687although there's not much a user program will do with it.
2688
2689   The big difference between an archive BFD and an ordinary BFD is
2690that the archive doesn't have sections.  Instead it has a chain of BFDs
2691that are considered its contents.  These BFDs can be manipulated like
2692any other.  The BFDs contained in an archive opened for reading will
2693all be opened for reading.  You may put either input or output BFDs
2694into an archive opened for output; they will be handled correctly when
2695the archive is closed.
2696
2697   Use `bfd_openr_next_archived_file' to step through the contents of
2698an archive opened for input.  You don't have to read the entire archive
2699if you don't want to!  Read it until you find what you want.
2700
2701   Archive contents of output BFDs are chained through the `next'
2702pointer in a BFD.  The first one is findable through the `archive_head'
2703slot of the archive.  Set it with `bfd_set_archive_head' (q.v.).  A
2704given BFD may be in only one open output archive at a time.
2705
2706   As expected, the BFD archive code is more general than the archive
2707code of any given environment.  BFD archives may contain files of
2708different formats (e.g., a.out and coff) and even different
2709architectures.  You may even place archives recursively into archives!
2710
2711   This can cause unexpected confusion, since some archive formats are
2712more expressive than others.  For instance, Intel COFF archives can
2713preserve long filenames; SunOS a.out archives cannot.  If you move a
2714file from the first to the second format and back again, the filename
2715may be truncated.  Likewise, different a.out environments have different
2716conventions as to how they truncate filenames, whether they preserve
2717directory names in filenames, etc.  When interoperating with native
2718tools, be sure your files are homogeneous.
2719
2720   Beware: most of these formats do not react well to the presence of
2721spaces in filenames.  We do the best we can, but can't always handle
2722this case due to restrictions in the format of archives.  Many Unix
2723utilities are braindead in regards to spaces and such in filenames
2724anyway, so this shouldn't be much of a restriction.
2725
2726   Archives are supported in BFD in `archive.c'.

2773================
2774
2775A format is a BFD concept of high level file contents type. The formats
2776supported by BFD are:
2777
2778   * `bfd_object'
2779   The BFD may contain data, symbols, relocations and debug info.
2780
2781   * `bfd_archive'
2782   The BFD contains other BFDs and an optional index.
2783
2784   * `bfd_core'
2785   The BFD contains the result of an executable core dump.

2794     bfd_boolean bfd_check_format (bfd *abfd, bfd_format format);
2795   *Description*
2796Verify if the file attached to the BFD ABFD is compatible with the
2797format FORMAT (i.e., one of `bfd_object', `bfd_archive' or `bfd_core').
2798
2799   If the BFD has been set to a specific target before the call, only
2800the named target and format combination is checked. If the target has
2801not been set, or has been set to `default', then all the known target
2802backends is interrogated to determine a match.  If the default target
2803matches, it is used.  If not, exactly one target must recognize the
2804file, or an error results.
2805
2806   The function returns `TRUE' on success, otherwise `FALSE' with one
2807of the following error codes:
2808
2809   * `bfd_error_invalid_operation' - if `format' is not one of
2810     `bfd_object', `bfd_archive' or `bfd_core'.
2811
2812   * `bfd_error_system_call' - if an error occured during a read - even
2813     some file mismatches can cause bfd_error_system_calls.
2814
2815   * `file_not_recognised' - none of the backends recognised the file
2816     format.
2817
2818   * `bfd_error_file_ambiguously_recognized' - more than one backend
2819     recognised the file format.

2824*Synopsis*
2825     bfd_boolean bfd_check_format_matches
2826        (bfd *abfd, bfd_format format, char ***matching);
2827   *Description*
2828Like `bfd_check_format', except when it returns FALSE with `bfd_errno'
2829set to `bfd_error_file_ambiguously_recognized'.  In that case, if
2830MATCHING is not NULL, it will be filled in with a NULL-terminated list
2831of the names of the formats that matched, allocated with `malloc'.
2832Then the user may choose a format and try again.
2833
2834   When done with the list that MATCHING points to, the caller should
2835free it.

2839
2840*Synopsis*
2841     bfd_boolean bfd_set_format (bfd *abfd, bfd_format format);
2842   *Description*
2843This function sets the file format of the BFD ABFD to the format
2844FORMAT. If the target set in the BFD does not support the format
2845requested, the format is invalid, or the BFD is not open for writing,
2846then an error occurs.

2853   *Description*
2854Return a pointer to a const string `invalid', `object', `archive',
2855`core', or `unknown', depending upon the value of FORMAT.

28602.10 Relocations
2861================
2862
2863BFD maintains relocations in much the same way it maintains symbols:
2864they are left alone until required, then read in en-masse and
2865translated into an internal form.  A common routine
2866`bfd_perform_relocation' acts upon the canonical form to do the fixup.
2867
2868   Relocations are maintained on a per section basis, while symbols are
2869maintained on a per BFD basis.
2870
2871   All that a back end has to do to fit the BFD interface is to create
2872a `struct reloc_cache_entry' for each relocation in a particular
2873section, and fill in the right bits of the structures.

2933       reloc_howto_type *howto;
2934
2935     }
2936     arelent;
2937   *Description*
2938Here is a description of each of the fields within an `arelent':
2939
2940   * `sym_ptr_ptr'
2941   The symbol table pointer points to a pointer to the symbol
2942associated with the relocation request.  It is the pointer into the
2943table returned by the back end's `canonicalize_symtab' action. *Note
2944Symbols::. The symbol is referenced through a pointer to a pointer so
2945that tools like the linker can fix up all the symbols of the same name
2946by modifying only one pointer. The relocation routine looks in the
2947symbol and uses the base of the section the symbol is attached to and
2948the value of the symbol as the initial relocation offset. If the symbol
2949pointer is zero, then the section provided is looked up.
2950
2951   * `address'
2952   The `address' field gives the offset in bytes from the base of the
2953section data which owns the relocation record to the first byte of
2954relocatable information. The actual data relocated will be relative to
2955this point; for example, a relocation type which modifies the bottom
2956two bytes of a four byte word would not touch the first byte pointed to
2957in a big endian world.
2958
2959   * `addend'
2960   The `addend' is a value provided by the back end to be added (!)  to
2961the relocation offset. Its interpretation is dependent upon the howto.
2962For example, on the 68k the code:
2963
2964             char foo[];
2965             main()
2966                     {
2967                     return foo[0x12345678];
2968                     }
2969
2970   Could be compiled into:
2971
2972             linkw fp,#-4
2973             moveb @#12345678,d0
2974             extbl d0
2975             unlk fp
2976             rts
2977
2978   This could create a reloc pointing to `foo', but leave the offset in
2979the data, something like:
2980
2981     RELOCATION RECORDS FOR [.text]:
2982     offset   type      value
2983     00000006 32        _foo
2984
2985     00000000 4e56 fffc          ; linkw fp,#-4
2986     00000004 1039 1234 5678     ; moveb @#12345678,d0
2987     0000000a 49c0               ; extbl d0
2988     0000000c 4e5e               ; unlk fp
2989     0000000e 4e75               ; rts
2990
2991   Using coff and an 88k, some instructions don't have enough space in
2992them to represent the full address range, and pointers have to be
2993loaded in two parts. So you'd get something like:
2994
2995             or.u     r13,r0,hi16(_foo+0x12345678)
2996             ld.b     r2,r13,lo16(_foo+0x12345678)
2997             jmp      r1
2998
2999   This should create two relocs, both pointing to `_foo', and with
30000x12340000 in their addend field. The data would consist of:
3001
3002     RELOCATION RECORDS FOR [.text]:
3003     offset   type      value
3004     00000002 HVRT16    _foo+0x12340000
3005     00000006 LVRT16    _foo+0x12340000
3006
3007     00000000 5da05678           ; or.u r13,r0,0x5678
3008     00000004 1c4d5678           ; ld.b r2,r13,0x5678
3009     00000008 f400c001           ; jmp r1
3010
3011   The relocation routine digs out the value from the data, adds it to
3012the addend to get the original offset, and then adds the value of
3013`_foo'. Note that all 32 bits have to be kept around somewhere, to cope
3014with carry from bit 15 to bit 16.
3015
3016   One further example is the sparc and the a.out format. The sparc has
3017a similar problem to the 88k, in that some instructions don't have room
3018for an entire offset, but on the sparc the parts are created in odd
3019sized lumps. The designers of the a.out format chose to not use the
3020data within the section for storing part of the offset; all the offset
3021is kept within the reloc. Anything in the data should be ignored.
3022
3023             save %sp,-112,%sp
3024             sethi %hi(_foo+0x12345678),%g2
3025             ldsb [%g2+%lo(_foo+0x12345678)],%i0
3026             ret
3027             restore
3028
3029   Both relocs contain a pointer to `foo', and the offsets contain junk.
3030
3031     RELOCATION RECORDS FOR [.text]:
3032     offset   type      value
3033     00000004 HI22      _foo+0x12345678
3034     00000008 LO10      _foo+0x12345678
3035
3036     00000000 9de3bf90     ; save %sp,-112,%sp
3037     00000004 05000000     ; sethi %hi(_foo+0),%g2
3038     00000008 f048a000     ; ldsb [%g2+%lo(_foo+0)],%i0
3039     0000000c 81c7e008     ; ret
3040     00000010 81e80000     ; restore
3041
3042   * `howto'
3043   The `howto' field can be imagined as a relocation instruction. It is
3044a pointer to a structure which contains information on what to do with
3045all of the other information in the reloc record and data section. A
3046back end would normally have a relocation instruction set and turn
3047relocations into pointers to the correct structure on input - but it
3048would be possible to create each howto field on demand.

3255   *Description*
3256If OUTPUT_BFD is supplied to this function, the generated image will be
3257relocatable; the relocations are copied to the output file after they
3258have been changed to reflect the new state of the world. There are two
3259ways of reflecting the results of partial linkage in an output file: by
3260modifying the output data in place, and by modifying the relocation
3261record.  Some native formats (e.g., basic a.out and basic coff) have no
3262way of specifying an addend in the relocation type, so the addend has
3263to go in the output data.  This is no big deal since in these formats
3264the output data slot will always be big enough for the addend. Complex
3265reloc types with addends were invented to solve just this problem.  The
3266ERROR_MESSAGE argument is set to an error message if this return
3267`bfd_reloc_dangerous'.

3280This looks remarkably like `bfd_perform_relocation', except it does not
3281expect that the section contents have been filled in.  I.e., it's
3282suitable for use when creating, rather than applying a relocation.

32902.10.2 The howto manager
3291------------------------
3292
3293When an application wants to create a relocation, but doesn't know what
3294the target machine might call it, it can find out by using this bit of
3295code.
3296
32972.10.2.1 `bfd_reloc_code_type'
3298..............................
3299
3300*Description*
3301The insides of a reloc code.  The idea is that, eventually, there will
3302be one enumerator for every type of relocation we ever do.  Pass one of
3303these values to `bfd_reloc_type_lookup', and it'll return a howto
3304pointer.
3305
3306   This does mean that the application must determine the correct
3307enumerator value; you can't get a howto pointer from a random set of
3308attributes.
3309
3310   Here are the possible values for `enum bfd_reloc_code_real':
3311
3312 -- : BFD_RELOC_64
3313 -- : BFD_RELOC_32

3316 -- : BFD_RELOC_16

3325 -- : BFD_RELOC_12_PCREL
3326 -- : BFD_RELOC_8_PCREL
3327     PC-relative relocations.  Sometimes these are relative to the
3328     address of the relocation itself; sometimes they are relative to
3329     the start of the section containing the relocation.  It depends on
3330     the specific target.
3331
3332     The 24-bit relocation is used in some Intel 960 configurations.
3333

3393 -- : BFD_RELOC_16_PCREL_S2
3394 -- : BFD_RELOC_23_PCREL_S2
3395     These PC-relative relocations are stored as word displacements -
3396     i.e., byte displacements shifted right two bits.  The 30-bit word
3397     displacement (<<32_PCREL_S2>> - 32 bits, shifted 2) is used on the
3398     SPARC.  (SPARC tools generally refer to this as <<WDISP30>>.)  The
3399     signed 16-bit displacement is used on the MIPS, and the 23-bit
3400     displacement is used on the Alpha.
3401
3402 -- : BFD_RELOC_HI22
3403 -- : BFD_RELOC_LO10
3404     High 22 bits and low 10 bits of 32-bit value, placed into lower

3406
3407 -- : BFD_RELOC_GPREL16
3408 -- : BFD_RELOC_GPREL32
3409     For systems that allocate a Global Pointer register, these are
3410     displacements off that register.  These relocation types are
3411     handled specially, because the value the register will have is
3412     decided relatively late.

3520 -- : BFD_RELOC_ALPHA_GPDISP_HI16
3521     Alpha ECOFF and ELF relocations.  Some of these treat the symbol or
3522     "addend" in some special way.  For GPDISP_HI16 ("gpdisp")
3523     relocations, the symbol is ignored when writing; when reading, it
3524     will be the absolute section symbol.  The addend is the
3525     displacement in bytes of the "lda" instruction from the "ldah"
3526     instruction (which is at the address of this reloc).
3527
3528 -- : BFD_RELOC_ALPHA_GPDISP_LO16
3529     For GPDISP_LO16 ("ignore") relocations, the symbol is handled as
3530     with GPDISP_HI16 relocs.  The addend is ignored when writing the
3531     relocations out, and is filled in with the file's GP value on
3532     reading, for convenience.
3533
3534 -- : BFD_RELOC_ALPHA_GPDISP
3535     The ELF GPDISP relocation is exactly the same as the GPDISP_HI16
3536     relocation except that there is no accompanying GPDISP_LO16
3537     relocation.
3538
3539 -- : BFD_RELOC_ALPHA_LITERAL
3540 -- : BFD_RELOC_ALPHA_ELF_LITERAL
3541 -- : BFD_RELOC_ALPHA_LITUSE
3542     The Alpha LITERAL/LITUSE relocs are produced by a symbol reference;
3543     the assembler turns it into a LDQ instruction to load the address
3544     of the symbol, and then fills in a register in the real
3545     instruction.
3546
3547     The LITERAL reloc, at the LDQ instruction, refers to the .lita
3548     section symbol.  The addend is ignored when writing, but is filled
3549     in with the file's GP value on reading, for convenience, as with
3550     the GPDISP_LO16 reloc.
3551
3552     The ELF_LITERAL reloc is somewhere between 16_GOTOFF and
3553     GPDISP_LO16.  It should refer to the symbol to be referenced, as
3554     with 16_GOTOFF, but it generates output not based on the position
3555     within the .got section, but relative to the GP value chosen for
3556     the file during the final link stage.
3557
3558     The LITUSE reloc, on the instruction using the loaded address,
3559     gives information to the linker that it might be able to use to
3560     optimize away some literal section references.  The symbol is
3561     ignored (read as the absolute section symbol), and the "addend"
3562     indicates the type of instruction using the register: 1 - "memory"
3563     fmt insn 2 - byte-manipulation (byte offset reg) 3 - jsr (target
3564     of branch)
3565
3566 -- : BFD_RELOC_ALPHA_HINT
3567     The HINT relocation indicates a value that should be filled into
3568     the "hint" field of a jmp/jsr/ret instruction, for possible branch-
3569     prediction logic which may be provided on some processors.
3570
3571 -- : BFD_RELOC_ALPHA_LINKAGE
3572     The LINKAGE relocation outputs a linkage pair in the object file,
3573     which is filled by the linker.
3574
3575 -- : BFD_RELOC_ALPHA_CODEADDR
3576     The CODEADDR relocation outputs a STO_CA in the object file, which
3577     is filled by the linker.

5088     These two relocations are used by the linker to determine which of
5089     the entries in a C++ virtual function table are actually used.
5090     When the -gc-sections option is given, the linker will zero out
5091     the entries that are not used, so that the code for those
5092     functions need not be included in the output.
5093
5094     VTABLE_INHERIT is a zero-space relocation used to describe to the
5095     linker the inheritance tree of a C++ virtual function table.  The
5096     relocation's symbol should be the parent class' vtable, and the
5097     relocation should be located at the child vtable.
5098
5099     VTABLE_ENTRY is a zero-space relocation that describes the use of a
5100     virtual function table entry.  The reloc's symbol should refer to
5101     the table of the class mentioned in the code.  Off of that base,
5102     an offset describes the entry that is being used.  For Rela hosts,
5103     this offset is stored in the reloc's addend.  For Rel hosts, we
5104     are forced to put this offset in the reloc's section offset.

58272.12 Targets
5828============
5829
5830*Description*
5831Each port of BFD to a different machine requires the creation of a
5832target back end. All the back end provides to the root part of BFD is a
5833structure containing pointers to functions which perform certain low
5834level operations on files. BFD translates the applications's requests
5835through a pointer into calls to the back end routines.
5836
5837   When a file is opened with `bfd_openr', its format and target are
5838unknown. BFD uses various mechanisms to determine how to interpret the
5839file. The operations performed are:
5840
5841   * Create a BFD by calling the internal routine `_bfd_new_bfd', then
5842     call `bfd_find_target' with the target string supplied to
5843     `bfd_openr' and the new BFD pointer.
5844
5845   * If a null target string was provided to `bfd_find_target', look up
5846     the environment variable `GNUTARGET' and use that as the target
5847     string.
5848
5849   * If the target string is still `NULL', or the target string is
5850     `default', then use the first item in the target vector as the
5851     target type, and set `target_defaulted' in the BFD to cause
5852     `bfd_check_format' to loop through all the targets.  *Note
5853     bfd_target::.  *Note Formats::.
5854
5855   * Otherwise, inspect the elements in the target vector one by one,
5856     until a match on target name is found. When found, use it.
5857
5858   * Otherwise return the error `bfd_error_invalid_target' to
5859     `bfd_openr'.
5860
5861   * `bfd_openr' attempts to open the file using `bfd_open_file', and
5862     returns the BFD.
5863   Once the BFD has been opened and the target selected, the file
5864format may be determined. This is done by calling `bfd_check_format' on
5865the BFD with a suggested format.  If `target_defaulted' has been set,
5866each possible target type is tried to see if it recognizes the
5867specified format.  `bfd_check_format' returns `TRUE' when the caller
5868guesses right.

58772.12.1 bfd_target
5878-----------------
5879
5880*Description*
5881This structure contains everything that BFD knows about a target. It
5882includes things like its byte order, name, and which routines to call
5883to do various operations.
5884
5885   Every BFD points to a target structure with its `xvec' member.
5886
5887   The macros below are used to dispatch to functions through the
5888`bfd_target' vector. They are used in a number of macros further down
5889in `bfd.h', and are also used when calling various routines by hand
5890inside the BFD implementation.  The ARGLIST argument must be
5891parenthesized; it contains all the arguments to the called function.
5892
5893   They make the documentation (more) unpleasant to read, so if someone
5894wants to fix this and not break the above, please do.
5895     #define BFD_SEND(bfd, message, arglist) \
5896       ((*((bfd)->xvec->message)) arglist)
5897
5898     #ifdef DEBUG_BFD_SEND
5899     #undef BFD_SEND

5901       (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
5902         ((*((bfd)->xvec->message)) arglist) : \
5903         (bfd_assert (__FILE__,__LINE__), NULL))
5904     #endif
5905   For operations which index on the BFD format:
5906     #define BFD_SEND_FMT(bfd, message, arglist) \
5907       (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist)
5908

5910     #undef BFD_SEND_FMT
5911     #define BFD_SEND_FMT(bfd, message, arglist) \
5912       (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
5913        (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist) : \
5914        (bfd_assert (__FILE__,__LINE__), NULL))
5915     #endif
5916   This is the structure which defines the type of BFD this is.  The
5917`xvec' member of the struct `bfd' itself points here.  Each module that
5918implements access to a different target under BFD, defines one of these.
5919
5920   FIXME, these names should be rationalised with the names of the
5921entry points which call them. Too bad we can't have one macro to define
5922them both!

6336Return a pointer to the transfer vector for the object target named
6337TARGET_NAME.  If TARGET_NAME is `NULL', choose the one in the
6338environment variable `GNUTARGET'; if that is null or not defined, then
6339choose the first entry in the target list.  Passing in the string
6340"default" or setting the environment variable to "default" will cause
6341the first entry in the target list to be returned, and
6342"target_defaulted" will be set in the BFD if ABFD isn't `NULL'.  This
6343causes `bfd_check_format' to loop over all the targets to find the one
6344that matches the file being read.

6355   *Description*
6356Return a pointer to the transfer vector for the object target named
6357TARGET_NAME.  If TARGET_NAME is `NULL', choose the one in the
6358environment variable `GNUTARGET'; if that is null or not defined, then
6359choose the first entry in the target list.  Passing in the string

6363causes `bfd_check_format' to loop over all the targets to find the one
6364that matches the file being read.  If IS_BIGENDIAN is not `NULL', then
6365set this value to target's endian mode. True for big-endian, FALSE for
6366little-endian or for invalid target.  If UNDERSCORING is not `NULL',
6367then set this value to target's underscoring mode. Zero for
6368none-underscoring, -1 for invalid target, else the value of target
6369vector's symbol underscoring.  If DEF_TARGET_ARCH is not `NULL', then
6370set it to the architecture string specified by the target_name.

63972.13 Architectures
6398==================
6399
6400BFD keeps one atom in a BFD describing the architecture of the data
6401attached to the BFD: a pointer to a `bfd_arch_info_type'.
6402
6403   Pointers to structures can be requested independently of a BFD so
6404that an architecture's information can be interrogated without access
6405to an open BFD.
6406
6407   The architecture information is provided by each architecture
6408package.  The set of default architectures is selected by the macro
6409`SELECT_ARCHITECTURES'.  This is normally set up in the
6410`config/TARGET.mt' file of your choice.  If the name is not defined,
6411then all the architectures supported are included.
6412
6413   When BFD starts up, all the architectures are called with an
6414initialize method.  It is up to the architecture back end to insert as
6415many items into the list of architectures as it wants to; generally
6416this would be one for each machine and one for the default case (an
6417item with a machine field of 0).
6418
6419   BFD's idea of an architecture is implemented in `archures.c'.

6425This enum gives the object file's CPU architecture, in a global
6426sense--i.e., what processor family does it belong to?  Another field
6427indicates which processor within the family is in use.  The machine
6428gives a number which distinguishes different versions of the
6429architecture, containing, for example, 2 and 3 for Intel i960 KA and
6430i960 KB, and 68020 and 68030 for Motorola 68020 and 68030.

7006----------------------------------------
7007
70082.14.1.1 `bfd_fopen'
7009....................
7010
7011*Synopsis*
7012     bfd *bfd_fopen (const char *filename, const char *target,
7013         const char *mode, int fd);
7014   *Description*
7015Open the file FILENAME with the target TARGET.  Return a pointer to the
7016created BFD.  If FD is not -1, then `fdopen' is used to open the file;
7017otherwise, `fopen' is used.  MODE is passed directly to `fopen' or
7018`fdopen'.
7019
7020   Calls `bfd_find_target', so TARGET is interpreted as by that
7021function.
7022
7023   The new BFD is marked as cacheable iff FD is -1.
7024
7025   If `NULL' is returned then an error has occured.   Possible errors
7026are `bfd_error_no_memory', `bfd_error_invalid_target' or `system_call'
7027error.
7028
70292.14.1.2 `bfd_openr'
7030....................
7031
7032*Synopsis*
7033     bfd *bfd_openr (const char *filename, const char *target);
7034   *Description*
7035Open the file FILENAME (using `fopen') with the target TARGET.  Return
7036a pointer to the created BFD.
7037
7038   Calls `bfd_find_target', so TARGET is interpreted as by that
7039function.
7040
7041   If `NULL' is returned then an error has occured.   Possible errors
7042are `bfd_error_no_memory', `bfd_error_invalid_target' or `system_call'
7043error.
7044
70452.14.1.3 `bfd_fdopenr'
7046......................
7047
7048*Synopsis*
7049     bfd *bfd_fdopenr (const char *filename, const char *target, int fd);
7050   *Description*
7051`bfd_fdopenr' is to `bfd_fopenr' much like `fdopen' is to `fopen'.  It
7052opens a BFD on a file already described by the FD supplied.
7053
7054   When the file is later `bfd_close'd, the file descriptor will be
7055closed.  If the caller desires that this file descriptor be cached by
7056BFD (opened as needed, closed as needed to free descriptors for other
7057opens), with the supplied FD used as an initial file descriptor (but
7058subject to closure at any time), call bfd_set_cacheable(bfd, 1) on the
7059returned BFD.  The default is to assume no caching; the file descriptor
7060will remain open until `bfd_close', and will not be affected by BFD
7061operations on other files.
7062
7063   Possible errors are `bfd_error_no_memory',
7064`bfd_error_invalid_target' and `bfd_error_system_call'.
7065
70662.14.1.4 `bfd_openstreamr'
7067..........................
7068
7069*Synopsis*
7070     bfd *bfd_openstreamr (const char *, const char *, void *);
7071   *Description*
7072Open a BFD for read access on an existing stdio stream.  When the BFD
7073is passed to `bfd_close', the stream will be closed.
7074
70752.14.1.5 `bfd_openr_iovec'

7079     bfd *bfd_openr_iovec (const char *filename, const char *target,
7080         void *(*open_func) (struct bfd *nbfd,

7089         void *stream),
7090         int (*stat_func) (struct bfd *abfd,
7091         void *stream,
7092         struct stat *sb));
7093   *Description*
7094Create and return a BFD backed by a read-only STREAM.  The STREAM is
7095created using OPEN_FUNC, accessed using PREAD_FUNC and destroyed using
7096CLOSE_FUNC.
7097
7098   Calls `bfd_find_target', so TARGET is interpreted as by that
7099function.
7100
7101   Calls OPEN_FUNC (which can call `bfd_zalloc' and `bfd_get_filename')
7102to obtain the read-only stream backing the BFD.  OPEN_FUNC either
7103succeeds returning the non-`NULL' STREAM, or fails returning `NULL'
7104(setting `bfd_error').
7105
7106   Calls PREAD_FUNC to request NBYTES of data from STREAM starting at
7107OFFSET (e.g., via a call to `bfd_read').  PREAD_FUNC either succeeds
7108returning the number of bytes read (which can be less than NBYTES when
7109end-of-file), or fails returning -1 (setting `bfd_error').
7110
7111   Calls CLOSE_FUNC when the BFD is later closed using `bfd_close'.
7112CLOSE_FUNC either succeeds returning 0, or fails returning -1 (setting
7113`bfd_error').
7114
7115   Calls STAT_FUNC to fill in a stat structure for bfd_stat,
7116bfd_get_size, and bfd_get_mtime calls.  STAT_FUNC returns 0 on success,
7117or returns -1 on failure (setting `bfd_error').
7118
7119   If `bfd_openr_iovec' returns `NULL' then an error has occurred.
7120Possible errors are `bfd_error_no_memory', `bfd_error_invalid_target'
7121and `bfd_error_system_call'.
7122
71232.14.1.6 `bfd_openw'
7124....................
7125
7126*Synopsis*
7127     bfd *bfd_openw (const char *filename, const char *target);
7128   *Description*
7129Create a BFD, associated with file FILENAME, using the file format
7130TARGET, and return a pointer to it.
7131
7132   Possible errors are `bfd_error_system_call', `bfd_error_no_memory',
7133`bfd_error_invalid_target'.
7134
71352.14.1.7 `bfd_close'
7136....................
7137
7138*Synopsis*
7139     bfd_boolean bfd_close (bfd *abfd);
7140   *Description*
7141Close a BFD. If the BFD was open for writing, then pending operations
7142are completed and the file written out and closed.  If the created file
7143is executable, then `chmod' is called to mark it as such.
7144
7145   All memory attached to the BFD is released.
7146
7147   The file descriptor associated with the BFD is closed (even if it
7148was passed in to BFD by `bfd_fdopenr').
7149
7150   *Returns*
7151`TRUE' is returned if all is ok, otherwise `FALSE'.
7152
71532.14.1.8 `bfd_close_all_done'
7154.............................
7155
7156*Synopsis*
7157     bfd_boolean bfd_close_all_done (bfd *);
7158   *Description*
7159Close a BFD.  Differs from `bfd_close' since it does not complete any
7160pending operations.  This routine would be used if the application had
7161just used BFD for swapping and didn't want to use any of the writing
7162code.
7163
7164   If the created file is executable, then `chmod' is called to mark it
7165as such.
7166
7167   All memory attached to the BFD is released.
7168
7169   *Returns*
7170`TRUE' is returned if all is ok, otherwise `FALSE'.
7171
71722.14.1.9 `bfd_create'
7173.....................
7174
7175*Synopsis*
7176     bfd *bfd_create (const char *filename, bfd *templ);
7177   *Description*
7178Create a new BFD in the manner of `bfd_openw', but without opening a
7179file. The new BFD takes the target from the target used by TEMPL. The
7180format is always set to `bfd_object'.
7181
71822.14.1.10 `bfd_make_writable'
7183.............................
7184
7185*Synopsis*
7186     bfd_boolean bfd_make_writable (bfd *abfd);
7187   *Description*
7188Takes a BFD as created by `bfd_create' and converts it into one like as
7189returned by `bfd_openw'.  It does this by converting the BFD to
7190BFD_IN_MEMORY.  It's assumed that you will call `bfd_make_readable' on
7191this bfd later.
7192
7193   *Returns*
7194`TRUE' is returned if all is ok, otherwise `FALSE'.
7195
71962.14.1.11 `bfd_make_readable'
7197.............................
7198
7199*Synopsis*
7200     bfd_boolean bfd_make_readable (bfd *abfd);
7201   *Description*
7202Takes a BFD as created by `bfd_create' and `bfd_make_writable' and
7203converts it into one like as returned by `bfd_openr'.  It does this by
7204writing the contents out to the memory buffer, then reversing the
7205direction.
7206
7207   *Returns*
7208`TRUE' is returned if all is ok, otherwise `FALSE'.

7283     char *find_separate_debug_file (bfd *abfd);
7284   *Description*
7285Searches ABFD for a reference to separate debugging information, scans
7286various locations in the filesystem, including the file tree rooted at
7287DEBUG_FILE_DIRECTORY, and returns a filename of such debugging
7288information if the file is found and has matching CRC32.  Returns NULL
7289if no reference to debugging file exists, or file cannot be found.

7296   *Description*
7297Takes a BFD and searches it for a .gnu_debuglink section.  If this
7298section is found, it examines the section for the name and checksum of
7299a '.debug' file containing auxiliary debugging information.  It then
7300searches the filesystem for this .debug file in some standard
7301locations, including the directory tree rooted at DIR, and if found
7302returns the full filename.
7303
7304   If DIR is NULL, it will search a default path configured into libbfd
7305at build time.  [XXX this feature is not currently implemented].
7306
7307   *Returns*
7308`NULL' on any errors or failure to locate the .debug file, otherwise a

73472.15.1 Internal functions
7348-------------------------
7349
7350*Description*
7351These routines are used within BFD.  They are not intended for export,
7352but are documented here for completeness.
7353
73542.15.1.1 `bfd_write_bigendian_4byte_int'
7355........................................
7356
7357*Synopsis*
7358     bfd_boolean bfd_write_bigendian_4byte_int (bfd *, unsigned int);
7359   *Description*
7360Write a 4 byte integer I to the output BFD ABFD, in big endian order
7361regardless of what else is going on.  This is useful in archives.
7362
73632.15.1.2 `bfd_put_size'
7364.......................
7365
73662.15.1.3 `bfd_get_size'
7367.......................
7368
7369*Description*
7370These macros as used for reading and writing raw data in sections; each
7371access (except for bytes) is vectored through the target format of the
7372BFD and mangled accordingly. The mangling performs any necessary endian
7373translations and removes alignment restrictions.  Note that types
7374accepted and returned by these macros are identical so they can be
7375swapped around in macros--for example, `libaout.h' defines `GET_WORD'
7376to either `bfd_get_32' or `bfd_get_64'.
7377
7378   In the put routines, VAL must be a `bfd_vma'.  If we are on a system
7379without prototypes, the caller is responsible for making sure that is
7380true, with a cast if necessary.  We don't cast them in the macro
7381definitions because that would prevent `lint' or `gcc -Wall' from
7382detecting sins such as passing a pointer.  To detect calling these with
7383less than a `bfd_vma', use `gcc -Wconversion' on a host with 64 bit
7384`bfd_vma''s.

75172.16 File caching
7518=================
7519
7520The file caching mechanism is embedded within BFD and allows the
7521application to open as many BFDs as it wants without regard to the
7522underlying operating system's file descriptor limit (often as low as 20
7523open files).  The module in `cache.c' maintains a least recently used
7524list of `BFD_CACHE_MAX_OPEN' files, and exports the name
7525`bfd_cache_lookup', which runs around and makes sure that the required
7526BFD is open. If not, then it chooses a file to close, closes it and
7527opens the one wanted, returning its file handle.

75812.17 Linker Functions
7582=====================
7583
7584The linker uses three special entry points in the BFD target vector.
7585It is not necessary to write special routines for these entry points
7586when creating a new BFD back end, since generic versions are provided.
7587However, writing them can speed up linking and make it use
7588significantly less runtime memory.
7589
7590   The first routine creates a hash table used by the other routines.
7591The second routine adds the symbols from an object file to the hash
7592table.  The third routine takes all the object files and links them
7593together to create the output file.  These routines are designed so
7594that the linker proper does not need to know anything about the symbols
7595in the object files that it is linking.  The linker merely arranges the
7596sections as directed by the linker script and lets BFD handle the
7597details of symbols and relocs.
7598
7599   The second routine and third routines are passed a pointer to a
7600`struct bfd_link_info' structure (defined in `bfdlink.h') which holds
7601information relevant to the link, including the linker hash table
7602(which was created by the first routine) and a set of callback
7603functions to the linker proper.
7604
7605   The generic linker routines are in `linker.c', and use the header
7606file `genlink.h'.  As of this writing, the only back ends which have
7607implemented versions of these routines are a.out (in `aoutx.h') and
7608ECOFF (in `ecoff.c').  The a.out routines are used as examples
7609throughout this section.

7619
76202.17.1 Creating a linker hash table
7621-----------------------------------
7622
7623The linker routines must create a hash table, which must be derived
7624from `struct bfd_link_hash_table' described in `bfdlink.c'.  *Note Hash
7625Tables::, for information on how to create a derived hash table.  This
7626entry point is called using the target vector of the linker output file.
7627
7628   The `_bfd_link_hash_table_create' entry point must allocate and
7629initialize an instance of the desired hash table.  If the back end does
7630not require any additional information to be stored with the entries in
7631the hash table, the entry point may simply create a `struct
7632bfd_link_hash_table'.  Most likely, however, some additional
7633information will be needed.
7634
7635   For example, with each entry in the hash table the a.out linker
7636keeps the index the symbol has in the final output file (this index
7637number is used so that when doing a relocatable link the symbol index
7638used in the output file can be quickly filled in when copying over a
7639reloc).  The a.out linker code defines the required structures and
7640functions for a hash table derived from `struct bfd_link_hash_table'.
7641The a.out linker hash table is created by the function
7642`NAME(aout,link_hash_table_create)'; it simply allocates space for the
7643hash table, initializes it, and returns a pointer to it.
7644
7645   When writing the linker routines for a new back end, you will
7646generally not know exactly which fields will be required until you have
7647finished.  You should simply create a new hash table which defines no
7648additional fields, and then simply add fields as they become necessary.

7652
76532.17.2 Adding symbols to the hash table
7654---------------------------------------
7655
7656The linker proper will call the `_bfd_link_add_symbols' entry point for
7657each object file or archive which is to be linked (typically these are
7658the files named on the command line, but some may also come from the
7659linker script).  The entry point is responsible for examining the file.
7660For an object file, BFD must add any relevant symbol information to
7661the hash table.  For an archive, BFD must determine which elements of
7662the archive should be used and adding them to the link.
7663
7664   The a.out version of this entry point is
7665`NAME(aout,link_add_symbols)'.

76762.17.2.1 Differing file formats
7677...............................
7678
7679Normally all the files involved in a link will be of the same format,
7680but it is also possible to link together different format object files,
7681and the back end must support that.  The `_bfd_link_add_symbols' entry
7682point is called via the target vector of the file to be added.  This
7683has an important consequence: the function may not assume that the hash
7684table is the type created by the corresponding
7685`_bfd_link_hash_table_create' vector.  All the `_bfd_link_add_symbols'
7686function can assume about the hash table is that it is derived from
7687`struct bfd_link_hash_table'.
7688
7689   Sometimes the `_bfd_link_add_symbols' function must store some
7690information in the hash table entry to be used by the `_bfd_final_link'
7691function.  In such a case the output bfd xvec must be checked to make
7692sure that the hash table was created by an object file of the same
7693format.
7694
7695   The `_bfd_final_link' routine must be prepared to handle a hash
7696entry without any extra information added by the
7697`_bfd_link_add_symbols' function.  A hash entry without extra
7698information will also occur when the linker script directs the linker
7699to create a symbol.  Note that, regardless of how a hash table entry is
7700added, all the fields will be initialized to some sort of null value by
7701the hash table entry initialization function.
7702
7703   See `ecoff_link_add_externals' for an example of how to check the
7704output bfd before saving information (in this case, the ECOFF external
7705symbol debugging information) in a hash table entry.

77102.17.2.2 Adding symbols from an object file
7711...........................................
7712
7713When the `_bfd_link_add_symbols' routine is passed an object file, it
7714must add all externally visible symbols in that object file to the hash
7715table.  The actual work of adding the symbol to the hash table is
7716normally handled by the function `_bfd_generic_link_add_one_symbol'.
7717The `_bfd_link_add_symbols' routine is responsible for reading all the
7718symbols from the object file and passing the correct information to
7719`_bfd_generic_link_add_one_symbol'.
7720
7721   The `_bfd_link_add_symbols' routine should not use
7722`bfd_canonicalize_symtab' to read the symbols.  The point of providing
7723this routine is to avoid the overhead of converting the symbols into
7724generic `asymbol' structures.
7725
7726   `_bfd_generic_link_add_one_symbol' handles the details of combining
7727common symbols, warning about multiple definitions, and so forth.  It
7728takes arguments which describe the symbol to add, notably symbol flags,
7729a section, and an offset.  The symbol flags include such things as
7730`BSF_WEAK' or `BSF_INDIRECT'.  The section is a section in the object
7731file, or something like `bfd_und_section_ptr' for an undefined symbol
7732or `bfd_com_section_ptr' for a common symbol.
7733
7734   If the `_bfd_final_link' routine is also going to need to read the
7735symbol information, the `_bfd_link_add_symbols' routine should save it
7736somewhere attached to the object file BFD.  However, the information
7737should only be saved if the `keep_memory' field of the `info' argument
7738is TRUE, so that the `-no-keep-memory' linker switch is effective.
7739
7740   The a.out function which adds symbols from an object file is
7741`aout_link_add_object_symbols', and most of the interesting work is in
7742`aout_link_add_symbols'.  The latter saves pointers to the hash tables
7743entries created by `_bfd_generic_link_add_one_symbol' indexed by symbol
7744number, so that the `_bfd_final_link' routine does not have to call the
7745hash table lookup routine to locate the entry.

7749
77502.17.2.3 Adding symbols from an archive
7751.......................................
7752
7753When the `_bfd_link_add_symbols' routine is passed an archive, it must
7754look through the symbols defined by the archive and decide which
7755elements of the archive should be included in the link.  For each such
7756element it must call the `add_archive_element' linker callback, and it
7757must add the symbols from the object file to the linker hash table.
7758(The callback may in fact indicate that a replacement BFD should be
7759used, in which case the symbols from that BFD should be added to the
7760linker hash table instead.)
7761
7762   In most cases the work of looking through the symbols in the archive
7763should be done by the `_bfd_generic_link_add_archive_symbols' function.
7764This function builds a hash table from the archive symbol table and
7765looks through the list of undefined symbols to see which elements
7766should be included.  `_bfd_generic_link_add_archive_symbols' is passed
7767a function to call to make the final decision about adding an archive
7768element to the link and to do the actual work of adding the symbols to
7769the linker hash table.
7770
7771   The function passed to `_bfd_generic_link_add_archive_symbols' must
7772read the symbols of the archive element and decide whether the archive
7773element should be included in the link.  If the element is to be
7774included, the `add_archive_element' linker callback routine must be
7775called with the element as an argument, and the element's symbols must
7776be added to the linker hash table just as though the element had itself
7777been passed to the `_bfd_link_add_symbols' function.  The
7778`add_archive_element' callback has the option to indicate that it would
7779like to replace the element archive with a substitute BFD, in which
7780case it is the symbols of that substitute BFD that must be added to the
7781linker hash table instead.
7782
7783   When the a.out `_bfd_link_add_symbols' function receives an archive,
7784it calls `_bfd_generic_link_add_archive_symbols' passing
7785`aout_link_check_archive_element' as the function argument.
7786`aout_link_check_archive_element' calls `aout_link_check_ar_symbols'.
7787If the latter decides to add the element (an element is only added if
7788it provides a real, non-common, definition for a previously undefined
7789or common symbol) it calls the `add_archive_element' callback and then
7790`aout_link_check_archive_element' calls `aout_link_add_symbols' to
7791actually add the symbols to the linker hash table - possibly those of a
7792substitute BFD, if the `add_archive_element' callback avails itself of
7793that option.
7794
7795   The ECOFF back end is unusual in that it does not normally call
7796`_bfd_generic_link_add_archive_symbols', because ECOFF archives already
7797contain a hash table of symbols.  The ECOFF back end searches the
7798archive itself to avoid the overhead of creating a new hash table.

78032.17.3 Performing the final link
7804--------------------------------
7805
7806When all the input files have been processed, the linker calls the
7807`_bfd_final_link' entry point of the output BFD.  This routine is
7808responsible for producing the final output file, which has several
7809aspects.  It must relocate the contents of the input sections and copy
7810the data into the output sections.  It must build an output symbol
7811table including any local symbols from the input files and the global
7812symbols from the hash table.  When producing relocatable output, it must
7813modify the input relocs and write them into the output file.  There may
7814also be object format dependent work to be done.
7815
7816   The linker will also call the `write_object_contents' entry point
7817when the BFD is closed.  The two entry points must work together in
7818order to produce the correct output file.
7819
7820   The details of how this works are inevitably dependent upon the
7821specific object file format.  The a.out `_bfd_final_link' routine is
7822`NAME(aout,final_link)'.

7834...........................................
7835
7836Before the linker calls the `_bfd_final_link' entry point, it sets up
7837some data structures for the function to use.
7838
7839   The `input_bfds' field of the `bfd_link_info' structure will point
7840to a list of all the input files included in the link.  These files are
7841linked through the `link_next' field of the `bfd' structure.
7842
7843   Each section in the output file will have a list of `link_order'
7844structures attached to the `map_head.link_order' field (the
7845`link_order' structure is defined in `bfdlink.h').  These structures
7846describe how to create the contents of the output section in terms of
7847the contents of various input sections, fill constants, and,
7848eventually, other types of information.  They also describe relocs that
7849must be created by the BFD backend, but do not correspond to any input
7850file; this is used to support -Ur, which builds constructors while
7851generating a relocatable object file.

78562.17.3.2 Relocating the section contents
7857........................................
7858
7859The `_bfd_final_link' function should look through the `link_order'
7860structures attached to each section of the output file.  Each
7861`link_order' structure should either be handled specially, or it should
7862be passed to the function `_bfd_default_link_order' which will do the
7863right thing (`_bfd_default_link_order' is defined in `linker.c').
7864
7865   For efficiency, a `link_order' of type `bfd_indirect_link_order'
7866whose associated section belongs to a BFD of the same format as the
7867output BFD must be handled specially.  This type of `link_order'
7868describes part of an output section in terms of a section belonging to
7869one of the input files.  The `_bfd_final_link' function should read the
7870contents of the section and any associated relocs, apply the relocs to
7871the section contents, and write out the modified section contents.  If
7872performing a relocatable link, the relocs themselves must also be
7873modified and written out.
7874
7875   The functions `_bfd_relocate_contents' and
7876`_bfd_final_link_relocate' provide some general support for performing
7877the actual relocations, notably overflow checking.  Their arguments
7878include information about the symbol the relocation is against and a
7879`reloc_howto_type' argument which describes the relocation to perform.
7880These functions are defined in `reloc.c'.
7881
7882   The a.out function which handles reading, relocating, and writing
7883section contents is `aout_link_input_section'.  The actual relocation
7884is done in `aout_link_input_section_std' and
7885`aout_link_input_section_ext'.

78902.17.3.3 Writing the symbol table
7891.................................
7892
7893The `_bfd_final_link' function must gather all the symbols in the input
7894files and write them out.  It must also write out all the symbols in
7895the global hash table.  This must be controlled by the `strip' and
7896`discard' fields of the `bfd_link_info' structure.
7897
7898   The local symbols of the input files will not have been entered into
7899the linker hash table.  The `_bfd_final_link' routine must consider
7900each input file and include the symbols in the output file.  It may be
7901convenient to do this when looking through the `link_order' structures,
7902or it may be done by stepping through the `input_bfds' list.
7903
7904   The `_bfd_final_link' routine must also traverse the global hash
7905table to gather all the externally visible symbols.  It is possible
7906that most of the externally visible symbols may be written out when
7907considering the symbols of each input file, but it is still necessary
7908to traverse the hash table since the linker script may have defined
7909some symbols that are not in any of the input files.
7910
7911   The `strip' field of the `bfd_link_info' structure controls which
7912symbols are written out.  The possible values are listed in
7913`bfdlink.h'.  If the value is `strip_some', then the `keep_hash' field
7914of the `bfd_link_info' structure is a hash table of symbols to keep;
7915each symbol should be looked up in this hash table, and only symbols
7916which are present should be included in the output file.
7917
7918   If the `strip' field of the `bfd_link_info' structure permits local
7919symbols to be written out, the `discard' field is used to further
7920controls which local symbols are included in the output file.  If the
7921value is `discard_l', then all local symbols which begin with a certain
7922prefix are discarded; this is controlled by the
7923`bfd_is_local_label_name' entry point.
7924
7925   The a.out backend handles symbols by calling
7926`aout_link_write_symbols' on each input BFD and then traversing the
7927global hash table with the function `aout_link_write_other_symbol'.  It
7928builds a string table while writing out the symbols, which is written
7929to the output file at the end of `NAME(aout,final_link)'.

79822.18 Hash Tables
7983================
7984
7985BFD provides a simple set of hash table functions.  Routines are
7986provided to initialize a hash table, to free a hash table, to look up a
7987string in a hash table and optionally create an entry for it, and to
7988traverse a hash table.  There is currently no routine to delete an
7989string from a hash table.
7990
7991   The basic hash table does not permit any data to be stored with a
7992string.  However, a hash table is designed to present a base class from
7993which other types of hash tables may be derived.  These derived types
7994may store additional information with the string.  Hash tables were
7995implemented in this way, rather than simply providing a data pointer in
7996a hash table entry, because they were designed for use by the linker
7997back ends.  The linker may create thousands of hash table entries, and
7998the overhead of allocating private data and storing and following
7999pointers becomes noticeable.
8000
8001   The basic hash table code is in `hash.c'.

8012
80132.18.1 Creating and freeing a hash table
8014----------------------------------------
8015
8016To create a hash table, create an instance of a `struct bfd_hash_table'
8017(defined in `bfd.h') and call `bfd_hash_table_init' (if you know
8018approximately how many entries you will need, the function
8019`bfd_hash_table_init_n', which takes a SIZE argument, may be used).
8020`bfd_hash_table_init' returns `FALSE' if some sort of error occurs.
8021
8022   The function `bfd_hash_table_init' take as an argument a function to
8023use to create new entries.  For a basic hash table, use the function
8024`bfd_hash_newfunc'.  *Note Deriving a New Hash Table Type::, for why
8025you would want to use a different value for this argument.
8026
8027   `bfd_hash_table_init' will create an objalloc which will be used to
8028allocate new entries.  You may allocate memory on this objalloc using
8029`bfd_hash_allocate'.
8030
8031   Use `bfd_hash_table_free' to free up all the memory that has been
8032allocated for a hash table.  This will not free up the `struct
8033bfd_hash_table' itself, which you must provide.
8034
8035   Use `bfd_hash_set_default_size' to set the default size of hash
8036table to use.

8040
80412.18.2 Looking up or entering a string
8042--------------------------------------
8043
8044The function `bfd_hash_lookup' is used both to look up a string in the
8045hash table and to create a new entry.
8046
8047   If the CREATE argument is `FALSE', `bfd_hash_lookup' will look up a
8048string.  If the string is found, it will returns a pointer to a `struct
8049bfd_hash_entry'.  If the string is not found in the table
8050`bfd_hash_lookup' will return `NULL'.  You should not modify any of the
8051fields in the returns `struct bfd_hash_entry'.
8052
8053   If the CREATE argument is `TRUE', the string will be entered into
8054the hash table if it is not already there.  Either way a pointer to a
8055`struct bfd_hash_entry' will be returned, either to the existing
8056structure or to a newly created one.  In this case, a `NULL' return
8057means that an error occurred.
8058
8059   If the CREATE argument is `TRUE', and a new entry is created, the
8060COPY argument is used to decide whether to copy the string onto the
8061hash table objalloc or not.  If COPY is passed as `FALSE', you must be
8062careful not to deallocate or modify the string as long as the hash table
8063exists.

8067
80682.18.3 Traversing a hash table
8069------------------------------
8070
8071The function `bfd_hash_traverse' may be used to traverse a hash table,
8072calling a function on each element.  The traversal is done in a random
8073order.
8074
8075   `bfd_hash_traverse' takes as arguments a function and a generic
8076`void *' pointer.  The function is called with a hash table entry (a
8077`struct bfd_hash_entry *') and the generic pointer passed to
8078`bfd_hash_traverse'.  The function must return a `boolean' value, which
8079indicates whether to continue traversing the hash table.  If the
8080function returns `FALSE', `bfd_hash_traverse' will stop the traversal
8081and return immediately.

80862.18.4 Deriving a new hash table type
8087-------------------------------------
8088
8089Many uses of hash tables want to store additional information which
8090each entry in the hash table.  Some also find it convenient to store
8091additional information with the hash table itself.  This may be done
8092using a derived hash table.
8093
8094   Since C is not an object oriented language, creating a derived hash
8095table requires sticking together some boilerplate routines with a few
8096differences specific to the type of hash table you want to create.
8097
8098   An example of a derived hash table is the linker hash table.  The
8099structures for this are defined in `bfdlink.h'.  The functions are in
8100`linker.c'.
8101
8102   You may also derive a hash table from an already derived hash table.
8103For example, the a.out linker backend code uses a hash table derived
8104from the linker hash table.

81152.18.4.1 Define the derived structures
8116......................................
8117
8118You must define a structure for an entry in the hash table, and a
8119structure for the hash table itself.
8120
8121   The first field in the structure for an entry in the hash table must
8122be of the type used for an entry in the hash table you are deriving
8123from.  If you are deriving from a basic hash table this is `struct
8124bfd_hash_entry', which is defined in `bfd.h'.  The first field in the
8125structure for the hash table itself must be of the type of the hash
8126table you are deriving from itself.  If you are deriving from a basic
8127hash table, this is `struct bfd_hash_table'.
8128
8129   For example, the linker hash table defines `struct
8130bfd_link_hash_entry' (in `bfdlink.h').  The first field, `root', is of
8131type `struct bfd_hash_entry'.  Similarly, the first field in `struct
8132bfd_link_hash_table', `table', is of type `struct bfd_hash_table'.

8136
81372.18.4.2 Write the derived creation routine
8138...........................................
8139
8140You must write a routine which will create and initialize an entry in
8141the hash table.  This routine is passed as the function argument to
8142`bfd_hash_table_init'.
8143
8144   In order to permit other hash tables to be derived from the hash
8145table you are creating, this routine must be written in a standard way.
8146
8147   The first argument to the creation routine is a pointer to a hash
8148table entry.  This may be `NULL', in which case the routine should
8149allocate the right amount of space.  Otherwise the space has already
8150been allocated by a hash table type derived from this one.
8151
8152   After allocating space, the creation routine must call the creation
8153routine of the hash table type it is derived from, passing in a pointer
8154to the space it just allocated.  This will initialize any fields used
8155by the base hash table.
8156
8157   Finally the creation routine must initialize any local fields for
8158the new hash table type.
8159
8160   Here is a boilerplate example of a creation routine.  FUNCTION_NAME
8161is the name of the routine.  ENTRY_TYPE is the type of an entry in the
8162hash table you are creating.  BASE_NEWFUNC is the name of the creation
8163routine of the hash table type your hash table is derived from.
8164

8166     FUNCTION_NAME (struct bfd_hash_entry *entry,

8168                          const char *string)
8169     {
8170       struct ENTRY_TYPE *ret = (ENTRY_TYPE *) entry;
8171
8172      /* Allocate the structure if it has not already been allocated by a
8173         derived class.  */
8174       if (ret == NULL)
8175         {
8176           ret = bfd_hash_allocate (table, sizeof (* ret));
8177           if (ret == NULL)
8178             return NULL;
8179         }
8180
8181      /* Call the allocation method of the base class.  */
8182       ret = ((ENTRY_TYPE *)
8183             BASE_NEWFUNC ((struct bfd_hash_entry *) ret, table, string));
8184
8185      /* Initialize the local fields here.  */
8186
8187       return (struct bfd_hash_entry *) ret;
8188     }
8189   *Description*
8190The creation routine for the linker hash table, which is in `linker.c',
8191looks just like this example.  FUNCTION_NAME is
8192`_bfd_link_hash_newfunc'.  ENTRY_TYPE is `struct bfd_link_hash_entry'.
8193BASE_NEWFUNC is `bfd_hash_newfunc', the creation routine for a basic
8194hash table.
8195
8196   `_bfd_link_hash_newfunc' also initializes the local fields in a
8197linker hash table entry: `type', `written' and `next'.

82022.18.4.3 Write other derived routines
8203.....................................
8204
8205You will want to write other routines for your new hash table, as well.
8206
8207   You will want an initialization routine which calls the
8208initialization routine of the hash table you are deriving from and
8209initializes any other local fields.  For the linker hash table, this is
8210`_bfd_link_hash_table_init' in `linker.c'.
8211
8212   You will want a lookup routine which calls the lookup routine of the
8213hash table you are deriving from and casts the result.  The linker hash
8214table uses `bfd_link_hash_lookup' in `linker.c' (this actually takes an
8215additional argument which it uses to decide how to return the looked up
8216value).
8217
8218   You may want a traversal routine.  This should just call the
8219traversal routine of the hash table you are deriving from with
8220appropriate casts.  The linker hash table uses `bfd_link_hash_traverse'
8221in `linker.c'.
8222
8223   These routines may simply be defined as macros.  For example, the
8224a.out backend linker hash table, which is derived from the linker hash
8225table, uses macros for the lookup and traversal routines.  These are
8226`aout_link_hash_lookup' and `aout_link_hash_traverse' in aoutx.h.

8257BFD supports a number of different flavours of a.out format, though the
8258major differences are only the sizes of the structures on disk, and the
8259shape of the relocation information.
8260
8261   The support is split into a basic support file `aoutx.h' and other
8262files which derive functions from the base. One derivation file is
8263`aoutf1.h' (for a.out flavour 1), and adds to the basic a.out functions
8264support for sun3, sun4, 386 and 29k a.out files, to create a target
8265jump vector for a specific target.
8266
8267   This information is further split out into more specific files for
8268each machine, including `sunos.c' for sun3 and sun4, `newsos3.c' for
8269the Sony NEWS, and `demo64.c' for a demonstration of a 64 bit a.out
8270format.
8271
8272   The base file `aoutx.h' defines general mechanisms for reading and
8273writing records to and from disk and various other methods which BFD
8274requires. It is included by `aout32.c' and `aout64.c' to form the names
8275`aout_32_swap_exec_header_in', `aout_64_swap_exec_header_in', etc.
8276
8277   As an example, this is what goes on to make the back end for a sun4,
8278from `aout32.c':
8279
8280            #define ARCH_SIZE 32
8281            #include "aoutx.h"
8282
8283   Which exports names:
8284
8285            ...
8286            aout_32_canonicalize_reloc
8287            aout_32_find_nearest_line
8288            aout_32_get_lineno
8289            aout_32_get_reloc_upper_bound
8290            ...
8291
8292   from `sunos.c':
8293
8294            #define TARGET_NAME "a.out-sunos-big"
8295            #define VECNAME    sunos_big_vec
8296            #include "aoutf1.h"
8297
8298   requires all the names from `aout32.c', and produces the jump vector
8299
8300            sunos_big_vec
8301
8302   The file `host-aout.c' is a special case.  It is for a large set of
8303hosts that use "more or less standard" a.out files, and for which
8304cross-debugging is not interesting.  It uses the standard 32-bit a.out
8305support routines, but determines the file offsets and addresses of the
8306text, data, and BSS sections, the machine architecture and machine
8307type, and the entry point address, in a host-dependent manner.  Once
8308these values have been determined, generic code is used to handle the
8309object file.
8310
8311   When porting it to run on a new system, you must supply:
8312
8313             HOST_PAGE_SIZE
8314             HOST_SEGMENT_SIZE
8315             HOST_MACHINE_ARCH       (optional)
8316             HOST_MACHINE_MACHINE    (optional)
8317             HOST_TEXT_START_ADDR
8318             HOST_STACK_END_ADDR
8319
8320   in the file `../include/sys/h-XXX.h' (for your host).  These values,
8321plus the structures and macros defined in `a.out.h' on your host
8322system, will produce a BFD target that will access ordinary a.out files
8323on your host. To configure a new machine to use `host-aout.c', specify:
8324
8325            TDEFAULTS = -DDEFAULT_VECTOR=host_aout_big_vec
8326            TDEPFILES= host-aout.o trad-core.o
8327
8328   in the `config/XXX.mt' file, and modify `configure.in' to use the
8329`XXX.mt' file (by setting "`bfd_target=XXX'") when your configuration
8330is selected.

8334
8335*Description*
8336The file `aoutx.h' provides for both the _standard_ and _extended_
8337forms of a.out relocation records.
8338
8339   The standard records contain only an address, a symbol index, and a
8340type field. The extended records (used on 29ks and sparcs) also have a
8341full integer for an addend.

8439
84403.3 coff backends
8441=================
8442
8443BFD supports a number of different flavours of coff format.  The major
8444differences between formats are the sizes and alignments of fields in
8445structures on disk, and the occasional extra field.
8446
8447   Coff in all its varieties is implemented with a few common files and
8448a number of implementation specific files. For example, The 88k bcs
8449coff format is implemented in the file `coff-m88k.c'. This file
8450`#include's `coff/m88k.h' which defines the external structure of the
8451coff format for the 88k, and `coff/internal.h' which defines the
8452internal structure. `coff-m88k.c' also defines the relocations used by
8453the 88k format *Note Relocations::.
8454
8455   The Intel i960 processor version of coff is implemented in
8456`coff-i960.c'. This file has the same structure as `coff-m88k.c',
8457except that it includes `coff/i960.h' rather than `coff-m88k.h'.
8458
84593.3.1 Porting to a new version of coff
8460--------------------------------------
8461
8462The recommended method is to select from the existing implementations
8463the version of coff which is most like the one you want to use.  For
8464example, we'll say that i386 coff is the one you select, and that your
8465coff flavour is called foo.  Copy `i386coff.c' to `foocoff.c', copy
8466`../include/coff/i386.h' to `../include/coff/foo.h', and add the lines
8467to `targets.c' and `Makefile.in' so that your new back end is used.
8468Alter the shapes of the structures in `../include/coff/foo.h' so that
8469they match what you need. You will probably also have to add `#ifdef's
8470to the code in `coff/internal.h' and `coffcode.h' if your version of
8471coff is too wild.
8472
8473   You can verify that your new BFD backend works quite simply by
8474building `objdump' from the `binutils' directory, and making sure that
8475its version of what's going on and your host system's idea (assuming it
8476has the pretty standard coff dump utility, usually called `att-dump' or
8477just `dump') are the same.  Then clean up your code, and send what
8478you've done to Cygnus. Then your stuff will be in the next release, and
8479you won't have to keep integrating it.
8480
84813.3.2 How the coff backend works
8482--------------------------------
8483
84843.3.2.1 File layout
8485...................
8486
8487The Coff backend is split into generic routines that are applicable to
8488any Coff target and routines that are specific to a particular target.
8489The target-specific routines are further split into ones which are
8490basically the same for all Coff targets except that they use the
8491external symbol format or use different values for certain constants.
8492
8493   The generic routines are in `coffgen.c'.  These routines work for
8494any Coff target.  They use some hooks into the target specific code;
8495the hooks are in a `bfd_coff_backend_data' structure, one of which
8496exists for each target.
8497
8498   The essentially similar target-specific routines are in
8499`coffcode.h'.  This header file includes executable C code.  The
8500various Coff targets first include the appropriate Coff header file,
8501make any special defines that are needed, and then include `coffcode.h'.
8502
8503   Some of the Coff targets then also have additional routines in the
8504target source file itself.
8505
8506   For example, `coff-i960.c' includes `coff/internal.h' and
8507`coff/i960.h'.  It then defines a few constants, such as `I960', and
8508includes `coffcode.h'.  Since the i960 has complex relocation types,
8509`coff-i960.c' also includes some code to manipulate the i960 relocs.
8510This code is not in `coffcode.h' because it would not be used by any
8511other target.
8512
85133.3.2.2 Coff long section names
8514...............................
8515
8516In the standard Coff object format, section names are limited to the
8517eight bytes available in the `s_name' field of the `SCNHDR' section
8518header structure.  The format requires the field to be NUL-padded, but
8519not necessarily NUL-terminated, so the longest section names permitted
8520are a full eight characters.
8521
8522   The Microsoft PE variants of the Coff object file format add an
8523extension to support the use of long section names.  This extension is
8524defined in section 4 of the Microsoft PE/COFF specification (rev 8.1).
8525If a section name is too long to fit into the section header's `s_name'
8526field, it is instead placed into the string table, and the `s_name'
8527field is filled with a slash ("/") followed by the ASCII decimal
8528representation of the offset of the full name relative to the string
8529table base.
8530
8531   Note that this implies that the extension can only be used in object
8532files, as executables do not contain a string table.  The standard
8533specifies that long section names from objects emitted into executable
8534images are to be truncated.
8535
8536   However, as a GNU extension, BFD can generate executable images that
8537contain a string table and long section names.  This would appear to be
8538technically valid, as the standard only says that Coff debugging
8539information is deprecated, not forbidden, and in practice it works,
8540although some tools that parse PE files expecting the MS standard
8541format may become confused; `PEview' is one known example.
8542
8543   The functionality is supported in BFD by code implemented under the
8544control of the macro `COFF_LONG_SECTION_NAMES'.  If not defined, the
8545format does not support long section names in any way.  If defined, it
8546is used to initialise a flag, `_bfd_coff_long_section_names', and a
8547hook function pointer, `_bfd_coff_set_long_section_names', in the Coff
8548backend data structure.  The flag controls the generation of long
8549section names in output BFDs at runtime; if it is false, as it will be
8550by default when generating an executable image, long section names are
8551truncated; if true, the long section names extension is employed.  The
8552hook points to a function that allows the value of the flag to be
8553altered at runtime, on formats that support long section names at all;
8554on other formats it points to a stub that returns an error indication.
8555With input BFDs, the flag is set according to whether any long section
8556names are detected while reading the section headers.  For a completely
8557new BFD, the flag is set to the default for the target format.  This
8558information can be used by a client of the BFD library when deciding
8559what output format to generate, and means that a BFD that is opened for
8560read and subsequently converted to a writeable BFD and modified
8561in-place will retain whatever format it had on input.
8562
8563   If `COFF_LONG_SECTION_NAMES' is simply defined (blank), or is
8564defined to the value "1", then long section names are enabled by
8565default; if it is defined to the value zero, they are disabled by
8566default (but still accepted in input BFDs).  The header `coffcode.h'
8567defines a macro, `COFF_DEFAULT_LONG_SECTION_NAMES', which is used in
8568the backends to initialise the backend data structure fields
8569appropriately; see the comments for further detail.
8570
85713.3.2.3 Bit twiddling
8572.....................
8573
8574Each flavour of coff supported in BFD has its own header file
8575describing the external layout of the structures. There is also an
8576internal description of the coff layout, in `coff/internal.h'. A major
8577function of the coff backend is swapping the bytes and twiddling the
8578bits to translate the external form of the structures into the normal
8579internal form. This is all performed in the `bfd_swap'_thing_direction
8580routines. Some elements are different sizes between different versions
8581of coff; it is the duty of the coff version specific include file to
8582override the definitions of various packing routines in `coffcode.h'.
8583E.g., the size of line number entry in coff is sometimes 16 bits, and
8584sometimes 32 bits. `#define'ing `PUT_LNSZ_LNNO' and `GET_LNSZ_LNNO'
8585will select the correct one. No doubt, some day someone will find a
8586version of coff which has a varying field size not catered to at the
8587moment. To port BFD, that person will have to add more `#defines'.
8588Three of the bit twiddling routines are exported to `gdb';
8589`coff_swap_aux_in', `coff_swap_sym_in' and `coff_swap_lineno_in'. `GDB'
8590reads the symbol table on its own, but uses BFD to fix things up.  More
8591of the bit twiddlers are exported for `gas'; `coff_swap_aux_out',
8592`coff_swap_sym_out', `coff_swap_lineno_out', `coff_swap_reloc_out',
8593`coff_swap_filehdr_out', `coff_swap_aouthdr_out',
8594`coff_swap_scnhdr_out'. `Gas' currently keeps track of all the symbol
8595table and reloc drudgery itself, thereby saving the internal BFD
8596overhead, but uses BFD to swap things on the way out, making cross
8597ports much safer.  Doing so also allows BFD (and thus the linker) to
8598use the same header files as `gas', which makes one avenue to disaster
8599disappear.
8600
86013.3.2.4 Symbol reading
8602......................
8603
8604The simple canonical form for symbols used by BFD is not rich enough to
8605keep all the information available in a coff symbol table. The back end
8606gets around this problem by keeping the original symbol table around,
8607"behind the scenes".
8608
8609   When a symbol table is requested (through a call to
8610`bfd_canonicalize_symtab'), a request gets through to
8611`coff_get_normalized_symtab'. This reads the symbol table from the coff
8612file and swaps all the structures inside into the internal form. It
8613also fixes up all the pointers in the table (represented in the file by
8614offsets from the first symbol in the table) into physical pointers to
8615elements in the new internal table. This involves some work since the
8616meanings of fields change depending upon context: a field that is a
8617pointer to another structure in the symbol table at one moment may be
8618the size in bytes of a structure at the next.  Another pass is made
8619over the table. All symbols which mark file names (`C_FILE' symbols)
8620are modified so that the internal string points to the value in the
8621auxent (the real filename) rather than the normal text associated with
8622the symbol (`".file"').
8623
8624   At this time the symbol names are moved around. Coff stores all
8625symbols less than nine characters long physically within the symbol
8626table; longer strings are kept at the end of the file in the string
8627table. This pass moves all strings into memory and replaces them with
8628pointers to the strings.
8629
8630   The symbol table is massaged once again, this time to create the
8631canonical table used by the BFD application. Each symbol is inspected
8632in turn, and a decision made (using the `sclass' field) about the
8633various flags to set in the `asymbol'.  *Note Symbols::. The generated
8634canonical table shares strings with the hidden internal symbol table.
8635
8636   Any linenumbers are read from the coff file too, and attached to the
8637symbols which own the functions the linenumbers belong to.
8638
86393.3.2.5 Symbol writing
8640......................
8641
8642Writing a symbol to a coff file which didn't come from a coff file will
8643lose any debugging information. The `asymbol' structure remembers the
8644BFD from which the symbol was taken, and on output the back end makes
8645sure that the same destination target as source target is present.
8646
8647   When the symbols have come from a coff file then all the debugging
8648information is preserved.
8649
8650   Symbol tables are provided for writing to the back end in a vector
8651of pointers to pointers. This allows applications like the linker to
8652accumulate and output large symbol tables without having to do too much
8653byte copying.
8654
8655   This function runs through the provided symbol table and patches
8656each symbol marked as a file place holder (`C_FILE') to point to the
8657next file place holder in the list. It also marks each `offset' field
8658in the list with the offset from the first symbol of the current symbol.
8659
8660   Another function of this procedure is to turn the canonical value
8661form of BFD into the form used by coff. Internally, BFD expects symbol
8662values to be offsets from a section base; so a symbol physically at
86630x120, but in a section starting at 0x100, would have the value 0x20.
8664Coff expects symbols to contain their final value, so symbols have
8665their values changed at this point to reflect their sum with their
8666owning section.  This transformation uses the `output_section' field of
8667the `asymbol''s `asection' *Note Sections::.
8668
8669   * `coff_mangle_symbols'
8670   This routine runs though the provided symbol table and uses the
8671offsets generated by the previous pass and the pointers generated when
8672the symbol table was read in to create the structured hierarchy
8673required by coff. It changes each pointer to a symbol into the index
8674into the symbol table of the asymbol.
8675
8676   * `coff_write_symbols'
8677   This routine runs through the symbol table and patches up the
8678symbols from their internal form into the coff way, calls the bit
8679twiddlers, and writes out the table to the file.
8680
86813.3.2.6 `coff_symbol_type'
8682..........................
8683
8684*Description*
8685The hidden information for an `asymbol' is described in a

8693       unsigned int offset;

8695       /* Should the value of this symbol be renumbered.  Used for

90403.3.2.8 Writing relocations
9041...........................
9042
9043To write relocations, the back end steps though the canonical
9044relocation table and create an `internal_reloc'. The symbol index to
9045use is removed from the `offset' field in the symbol table supplied.
9046The address comes directly from the sum of the section base address and
9047the relocation offset; the type is dug directly from the howto field.
9048Then the `internal_reloc' is swapped into the shape of an
9049`external_reloc' and written out to disk.

90513.3.2.9 Reading linenumbers
9052...........................
9053
9054Creating the linenumber table is done by reading in the entire coff
9055linenumber table, and creating another table for internal use.
9056
9057   A coff linenumber table is structured so that each function is
9058marked as having a line number of 0. Each line within the function is
9059an offset from the first line in the function. The base of the line
9060number information for the table is stored in the symbol associated
9061with the function.
9062
9063   Note: The PE format uses line number 0 for a flag indicating a new
9064source file.
9065
9066   The information is copied from the external to the internal table,
9067and each symbol which marks a function is marked by pointing its...
9068
9069   How does this work ?

90713.3.2.10 Reading relocations
9072............................
9073
9074Coff relocations are easily transformed into the internal BFD form
9075(`arelent').
9076
9077   Reading a coff relocation table is done in the following stages:
9078
9079   * Read the entire coff relocation table into memory.
9080
9081   * Process each relocation in turn; first swap it from the external
9082     to the internal form.
9083
9084   * Turn the symbol referenced in the relocation's symbol index into a
9085     pointer into the canonical symbol table.  This table is the same
9086     as the one returned by a call to `bfd_canonicalize_symtab'. The
9087     back end will call that routine and save the result if a
9088     canonicalization hasn't been done.
9089
9090   * The reloc index is turned into a pointer to a howto structure, in
9091     a back end specific way. For instance, the 386 and 960 use the
9092     `r_type' to directly produce an index into a howto table vector;
9093     the 88k subtracts a number from the `r_type' field and creates an
9094     addend field.

90993.4 ELF backends
9100================
9101
9102BFD support for ELF formats is being worked on.  Currently, the best
9103supported back ends are for sparc and i386 (running svr4 or Solaris 2).
9104
9105   Documentation of the internals of the support code still needs to be
9106written.  The code is changing quickly enough that we haven't bothered
9107yet.

91123.5 mmo backend
9113===============
9114
9115The mmo object format is used exclusively together with Professor
9116Donald E. Knuth's educational 64-bit processor MMIX.  The simulator
9117`mmix' which is available at
9118`http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz'
9119understands this format.  That package also includes a combined
9120assembler and linker called `mmixal'.  The mmo format has no advantages
9121feature-wise compared to e.g. ELF.  It is a simple non-relocatable
9122object format with no support for archives or debugging information,
9123except for symbol value information and line numbers (which is not yet
9124implemented in BFD).  See
9125`http://www-cs-faculty.stanford.edu/~knuth/mmix.html' for more
9126information about MMIX.  The ELF format is used for intermediate object
9127files in the BFD implementation.

91383.5.1 File layout
9139-----------------
9140
9141The mmo file contents is not partitioned into named sections as with
9142e.g. ELF.  Memory areas is formed by specifying the location of the
9143data that follows.  Only the memory area `0x0000...00' to `0x01ff...ff'
9144is executable, so it is used for code (and constants) and the area
9145`0x2000...00' to `0x20ff...ff' is used for writable data.  *Note mmo
9146section mapping::.
9147
9148   There is provision for specifying "special data" of 65536 different
9149types.  We use type 80 (decimal), arbitrarily chosen the same as the
9150ELF `e_machine' number for MMIX, filling it with section information
9151normally found in ELF objects. *Note mmo section mapping::.
9152
9153   Contents is entered as 32-bit words, xor:ed over previous contents,
9154always zero-initialized.  A word that starts with the byte `0x98' forms
9155a command called a `lopcode', where the next byte distinguished between
9156the thirteen lopcodes.  The two remaining bytes, called the `Y' and `Z'
9157fields, or the `YZ' field (a 16-bit big-endian number), are used for
9158various purposes different for each lopcode.  As documented in
9159`http://www-cs-faculty.stanford.edu/~knuth/mmixal-intro.ps.gz', the
9160lopcodes are:
9161
9162`lop_quote'
9163     0x98000001.  The next word is contents, regardless of whether it
9164     starts with 0x98 or not.
9165
9166`lop_loc'
9167     0x9801YYZZ, where `Z' is 1 or 2.  This is a location directive,
9168     setting the location for the next data to the next 32-bit word
9169     (for Z = 1) or 64-bit word (for Z = 2), plus Y * 2^56.  Normally
9170     `Y' is 0 for the text segment and 2 for the data segment.
9171
9172`lop_skip'
9173     0x9802YYZZ.  Increase the current location by `YZ' bytes.
9174
9175`lop_fixo'
9176     0x9803YYZZ, where `Z' is 1 or 2.  Store the current location as 64
9177     bits into the location pointed to by the next 32-bit (Z = 1) or
9178     64-bit (Z = 2) word, plus Y * 2^56.
9179
9180`lop_fixr'
9181     0x9804YYZZ.  `YZ' is stored into the current location plus 2 - 4 *
9182     YZ.
9183
9184`lop_fixrx'
9185     0x980500ZZ.  `Z' is 16 or 24.  A value `L' derived from the
9186     following 32-bit word are used in a manner similar to `YZ' in
9187     lop_fixr: it is xor:ed into the current location minus 4 * L.  The
9188     first byte of the word is 0 or 1.  If it is 1, then L = (LOWEST 24
9189     BITS OF WORD) - 2^Z, if 0, then L = (LOWEST 24 BITS OF WORD).
9190
9191`lop_file'
9192     0x9806YYZZ.  `Y' is the file number, `Z' is count of 32-bit words.
9193     Set the file number to `Y' and the line counter to 0.  The next Z
9194     * 4 bytes contain the file name, padded with zeros if the count is
9195     not a multiple of four.  The same `Y' may occur multiple times,
9196     but `Z' must be 0 for all but the first occurrence.
9197
9198`lop_line'
9199     0x9807YYZZ.  `YZ' is the line number.  Together with lop_file, it
9200     forms the source location for the next 32-bit word.  Note that for
9201     each non-lopcode 32-bit word, line numbers are assumed incremented
9202     by one.
9203
9204`lop_spec'
9205     0x9808YYZZ.  `YZ' is the type number.  Data until the next lopcode
9206     other than lop_quote forms special data of type `YZ'.  *Note mmo
9207     section mapping::.
9208
9209     Other types than 80, (or type 80 with a content that does not
9210     parse) is stored in sections named `.MMIX.spec_data.N' where N is
9211     the `YZ'-type.  The flags for such a sections say not to allocate
9212     or load the data.  The vma is 0.  Contents of multiple occurrences
9213     of special data N is concatenated to the data of the previous
9214     lop_spec Ns.  The location in data or code at which the lop_spec
9215     occurred is lost.
9216
9217`lop_pre'
9218     0x980901ZZ.  The first lopcode in a file.  The `Z' field forms the
9219     length of header information in 32-bit words, where the first word
9220     tells the time in seconds since `00:00:00 GMT Jan 1 1970'.
9221
9222`lop_post'
9223     0x980a00ZZ.  Z > 32.  This lopcode follows after all
9224     content-generating lopcodes in a program.  The `Z' field denotes
9225     the value of `rG' at the beginning of the program.  The following
9226     256 - Z big-endian 64-bit words are loaded into global registers
9227     `$G' ... `$255'.
9228
9229`lop_stab'
9230     0x980b0000.  The next-to-last lopcode in a program.  Must follow
9231     immediately after the lop_post lopcode and its data.  After this
9232     lopcode follows all symbols in a compressed format (*note
9233     Symbol-table::).
9234
9235`lop_end'
9236     0x980cYYZZ.  The last lopcode in a program.  It must follow the
9237     lop_stab lopcode and its data.  The `YZ' field contains the number
9238     of 32-bit words of symbol table information after the preceding
9239     lop_stab lopcode.
9240
9241   Note that the lopcode "fixups"; `lop_fixr', `lop_fixrx' and
9242`lop_fixo' are not generated by BFD, but are handled.  They are
9243generated by `mmixal'.

92763.5.2 Symbol table format
9277-------------------------
9278
9279From mmixal.w (or really, the generated mmixal.tex) in
9280`http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz'):
9281"Symbols are stored and retrieved by means of a `ternary search trie',
9282following ideas of Bentley and Sedgewick. (See ACM-SIAM Symp. on
9283Discrete Algorithms `8' (1997), 360-369; R.Sedgewick, `Algorithms in C'
9284(Reading, Mass.  Addison-Wesley, 1998), `15.4'.)  Each trie node stores
9285a character, and there are branches to subtries for the cases where a
9286given character is less than, equal to, or greater than the character
9287in the trie.  There also is a pointer to a symbol table entry if a
9288symbol ends at the current node."
9289
9290   So it's a tree encoded as a stream of bytes.  The stream of bytes
9291acts on a single virtual global symbol, adding and removing characters
9292and signalling complete symbol points.  Here, we read the stream and
9293create symbols at the completion points.
9294
9295   First, there's a control byte `m'.  If any of the listed bits in `m'
9296is nonzero, we execute what stands at the right, in the listed order:
9297
9298      (MMO3_LEFT)
9299      0x40 - Traverse left trie.
9300             (Read a new command byte and recurse.)
9301
9302      (MMO3_SYMBITS)
9303      0x2f - Read the next byte as a character and store it in the
9304             current character position; increment character position.
9305             Test the bits of `m':
9306
9307             (MMO3_WCHAR)
9308             0x80 - The character is 16-bit (so read another byte,
9309                    merge into current character.
9310
9311             (MMO3_TYPEBITS)
9312             0xf  - We have a complete symbol; parse the type, value
9313                    and serial number and do what should be done
9314                    with a symbol.  The type and length information
9315                    is in j = (m & 0xf).
9316
9317                    (MMO3_REGQUAL_BITS)
9318                    j == 0xf: A register variable.  The following
9319                              byte tells which register.
9320                    j <= 8:   An absolute symbol.  Read j bytes as the
9321                              big-endian number the symbol equals.
9322                              A j = 2 with two zero bytes denotes an
9323                              unknown symbol.
9324                    j > 8:    As with j <= 8, but add (0x20 << 56)
9325                              to the value in the following j - 8
9326                              bytes.
9327
9328                    Then comes the serial number, as a variant of
9329                    uleb128, but better named ubeb128:
9330                    Read bytes and shift the previous value left 7
9331                    (multiply by 128).  Add in the new byte, repeat
9332                    until a byte has bit 7 set.  The serial number
9333                    is the computed value minus 128.
9334
9335             (MMO3_MIDDLE)
9336             0x20 - Traverse middle trie.  (Read a new command byte
9337                    and recurse.)  Decrement character position.
9338
9339      (MMO3_RIGHT)
9340      0x10 - Traverse right trie.  (Read a new command byte and
9341             recurse.)
9342
9343   Let's look again at the `lop_stab' for the trivial file (*note File
9344layout::).
9345
9346      0x980b0000 - lop_stab for ":Main" = 0, serial 1.
9347      0x203a4040
9348      0x10404020
9349      0x4d206120
9350      0x69016e00
9351      0x81000000
9352
9353   This forms the trivial trie (note that the path between ":" and "M"
9354is redundant):
9355
9356      203a     ":"
9357      40       /
9358      40      /
9359      10      \
9360      40      /
9361      40     /
9362      204d  "M"
9363      2061  "a"
9364      2069  "i"
9365      016e  "n" is the last character in a full symbol, and
9366            with a value represented in one byte.
9367      00    The value is 0.
9368      81    The serial number is 1.

93733.5.3 mmo section mapping
9374-------------------------
9375
9376The implementation in BFD uses special data type 80 (decimal) to
9377encapsulate and describe named sections, containing e.g. debug
9378information.  If needed, any datum in the encapsulation will be quoted
9379using lop_quote.  First comes a 32-bit word holding the number of
938032-bit words containing the zero-terminated zero-padded segment name.
9381After the name there's a 32-bit word holding flags describing the
9382section type.  Then comes a 64-bit big-endian word with the section
9383length (in bytes), then another with the section start address.
9384Depending on the type of section, the contents might follow,
9385zero-padded to 32-bit boundary.  For a loadable section (such as data
9386or code), the contents might follow at some later point, not
9387necessarily immediately, as a lop_loc with the same start address as in
9388the section description, followed by the contents.  This in effect
9389forms a descriptor that must be emitted before the actual contents.
9390Sections described this way must not overlap.
9391
9392   For areas that don't have such descriptors, synthetic sections are
9393formed by BFD.  Consecutive contents in the two memory areas
9394`0x0000...00' to `0x01ff...ff' and `0x2000...00' to `0x20ff...ff' are
9395entered in sections named `.text' and `.data' respectively.  If an area
9396is not otherwise described, but would together with a neighboring lower
9397area be less than `0x40000000' bytes long, it is joined with the lower
9398area and the gap is zero-filled.  For other cases, a new section is
9399formed, named `.MMIX.sec.N'.  Here, N is a number, a running count
9400through the mmo file, starting at 0.
9401
9402   A loadable section specified as:
9403
9404      .section secname,"ax"
9405      TETRA 1,2,3,4,-1,-2009
9406      BYTE 80
9407
9408   and linked to address `0x4', is represented by the sequence:
9409
9410      0x98080050 - lop_spec 80
9411      0x00000002 - two 32-bit words for the section name
9412      0x7365636e - "secn"
9413      0x616d6500 - "ame\0"
9414      0x00000033 - flags CODE, READONLY, LOAD, ALLOC
9415      0x00000000 - high 32 bits of section length
9416      0x0000001c - section length is 28 bytes; 6 * 4 + 1 + alignment to 32 bits
9417      0x00000000 - high 32 bits of section address
9418      0x00000004 - section address is 4
9419      0x98010002 - 64 bits with address of following data

9427      0xfffff827 - -2009
9428      0x50000000 - 80 as a byte, padded with zeros.
9429
9430   Note that the lop_spec wrapping does not include the section
9431contents.  Compare this to a non-loaded section specified as:
9432
9433      .section thirdsec
9434      TETRA 200001,100002
9435      BYTE 38,40
9436
9437   This, when linked to address `0x200000000000001c', is represented by:
9438
9439      0x98080050 - lop_spec 80
9440      0x00000002 - two 32-bit words for the section name
9441      0x7365636e - "thir"
9442      0x616d6500 - "dsec"
9443      0x00000010 - flag READONLY
9444      0x00000000 - high 32 bits of section length
9445      0x0000000c - section length is 12 bytes; 2 * 4 + 2 + alignment to 32 bits
9446      0x20000000 - high 32 bits of address
9447      0x0000001c - low 32 bits of address 0x200000000000001c
9448      0x00030d41 - 200001
9449      0x000186a2 - 100002
9450      0x26280000 - 38, 40 as bytes, padded with zeros
9451
9452   For the latter example, the section contents must not be loaded in
9453memory, and is therefore specified as part of the special data.  The
9454address is usually unimportant but might provide information for e.g.
9455the DWARF 2 debugging format.

9465     Everyone is permitted to copy and distribute verbatim copies
9466     of this license document, but changing it is not allowed.
9467
9468  0. PREAMBLE
9469
9470     The purpose of this License is to make a manual, textbook, or other
9471     functional and useful document "free" in the sense of freedom: to
9472     assure everyone the effective freedom to copy and redistribute it,
9473     with or without modifying it, either commercially or
9474     noncommercially.  Secondarily, this License preserves for the
9475     author and publisher a way to get credit for their work, while not
9476     being considered responsible for modifications made by others.
9477
9478     This License is a kind of "copyleft", which means that derivative
9479     works of the document must themselves be free in the same sense.
9480     It complements the GNU General Public License, which is a copyleft
9481     license designed for free software.
9482
9483     We have designed this License in order to use it for manuals for
9484     free software, because free software needs free documentation: a
9485     free program should come with manuals providing the same freedoms
9486     that the software does.  But this License is not limited to
9487     software manuals; it can be used for any textual work, regardless
9488     of subject matter or whether it is published as a printed book.
9489     We recommend this License principally for works whose purpose is
9490     instruction or reference.
9491
9492  1. APPLICABILITY AND DEFINITIONS
9493
9494     This License applies to any manual or other work, in any medium,
9495     that contains a notice placed by the copyright holder saying it
9496     can be distributed under the terms of this License.  Such a notice
9497     grants a world-wide, royalty-free license, unlimited in duration,
9498     to use that work under the conditions stated herein.  The
9499     "Document", below, refers to any such manual or work.  Any member
9500     of the public is a licensee, and is addressed as "you".  You
9501     accept the license if you copy, modify or distribute the work in a
9502     way requiring permission under copyright law.
9503
9504     A "Modified Version" of the Document means any work containing the
9505     Document or a portion of it, either copied verbatim, or with
9506     modifications and/or translated into another language.
9507
9508     A "Secondary Section" is a named appendix or a front-matter section
9509     of the Document that deals exclusively with the relationship of the
9510     publishers or authors of the Document to the Document's overall
9511     subject (or to related matters) and contains nothing that could
9512     fall directly within that overall subject.  (Thus, if the Document
9513     is in part a textbook of mathematics, a Secondary Section may not
9514     explain any mathematics.)  The relationship could be a matter of
9515     historical connection with the subject or with related matters, or
9516     of legal, commercial, philosophical, ethical or political position
9517     regarding them.
9518
9519     The "Invariant Sections" are certain Secondary Sections whose
9520     titles are designated, as being those of Invariant Sections, in
9521     the notice that says that the Document is released under this
9522     License.  If a section does not fit the above definition of
9523     Secondary then it is not allowed to be designated as Invariant.
9524     The Document may contain zero Invariant Sections.  If the Document
9525     does not identify any Invariant Sections then there are none.
9526
9527     The "Cover Texts" are certain short passages of text that are
9528     listed, as Front-Cover Texts or Back-Cover Texts, in the notice
9529     that says that the Document is released under this License.  A
9530     Front-Cover Text may be at most 5 words, and a Back-Cover Text may
9531     be at most 25 words.
9532
9533     A "Transparent" copy of the Document means a machine-readable copy,
9534     represented in a format whose specification is available to the
9535     general public, that is suitable for revising the document
9536     straightforwardly with generic text editors or (for images
9537     composed of pixels) generic paint programs or (for drawings) some
9538     widely available drawing editor, and that is suitable for input to
9539     text formatters or for automatic translation to a variety of
9540     formats suitable for input to text formatters.  A copy made in an
9541     otherwise Transparent file format whose markup, or absence of
9542     markup, has been arranged to thwart or discourage subsequent
9543     modification by readers is not Transparent.  An image format is
9544     not Transparent if used for any substantial amount of text.  A
9545     copy that is not "Transparent" is called "Opaque".
9546
9547     Examples of suitable formats for Transparent copies include plain
9548     ASCII without markup, Texinfo input format, LaTeX input format,
9549     SGML or XML using a publicly available DTD, and
9550     standard-conforming simple HTML, PostScript or PDF designed for
9551     human modification.  Examples of transparent image formats include
9552     PNG, XCF and JPG.  Opaque formats include proprietary formats that
9553     can be read and edited only by proprietary word processors, SGML or
9554     XML for which the DTD and/or processing tools are not generally
9555     available, and the machine-generated HTML, PostScript or PDF
9556     produced by some word processors for output purposes only.
9557
9558     The "Title Page" means, for a printed book, the title page itself,
9559     plus such following pages as are needed to hold, legibly, the
9560     material this License requires to appear in the title page.  For
9561     works in formats which do not have any title page as such, "Title
9562     Page" means the text near the most prominent appearance of the
9563     work's title, preceding the beginning of the body of the text.
9564
9565     The "publisher" means any person or entity that distributes copies
9566     of the Document to the public.
9567
9568     A section "Entitled XYZ" means a named subunit of the Document
9569     whose title either is precisely XYZ or contains XYZ in parentheses
9570     following text that translates XYZ in another language.  (Here XYZ
9571     stands for a specific section name mentioned below, such as
9572     "Acknowledgements", "Dedications", "Endorsements", or "History".)
9573     To "Preserve the Title" of such a section when you modify the
9574     Document means that it remains a section "Entitled XYZ" according
9575     to this definition.
9576
9577     The Document may include Warranty Disclaimers next to the notice
9578     which states that this License applies to the Document.  These
9579     Warranty Disclaimers are considered to be included by reference in
9580     this License, but only as regards disclaiming warranties: any other
9581     implication that these Warranty Disclaimers may have is void and
9582     has no effect on the meaning of this License.
9583
9584  2. VERBATIM COPYING
9585
9586     You may copy and distribute the Document in any medium, either
9587     commercially or noncommercially, provided that this License, the
9588     copyright notices, and the license notice saying this License
9589     applies to the Document are reproduced in all copies, and that you
9590     add no other conditions whatsoever to those of this License.  You
9591     may not use technical measures to obstruct or control the reading
9592     or further copying of the copies you make or distribute.  However,
9593     you may accept compensation in exchange for copies.  If you
9594     distribute a large enough number of copies you must also follow
9595     the conditions in section 3.
9596
9597     You may also lend copies, under the same conditions stated above,
9598     and you may publicly display copies.
9599
9600  3. COPYING IN QUANTITY
9601
9602     If you publish printed copies (or copies in media that commonly
9603     have printed covers) of the Document, numbering more than 100, and
9604     the Document's license notice requires Cover Texts, you must
9605     enclose the copies in covers that carry, clearly and legibly, all
9606     these Cover Texts: Front-Cover Texts on the front cover, and
9607     Back-Cover Texts on the back cover.  Both covers must also clearly
9608     and legibly identify you as the publisher of these copies.  The
9609     front cover must present the full title with all words of the
9610     title equally prominent and visible.  You may add other material
9611     on the covers in addition.  Copying with changes limited to the
9612     covers, as long as they preserve the title of the Document and
9613     satisfy these conditions, can be treated as verbatim copying in
9614     other respects.
9615
9616     If the required texts for either cover are too voluminous to fit
9617     legibly, you should put the first ones listed (as many as fit
9618     reasonably) on the actual cover, and continue the rest onto
9619     adjacent pages.
9620
9621     If you publish or distribute Opaque copies of the Document
9622     numbering more than 100, you must either include a
9623     machine-readable Transparent copy along with each Opaque copy, or
9624     state in or with each Opaque copy a computer-network location from
9625     which the general network-using public has access to download
9626     using public-standard network protocols a complete Transparent
9627     copy of the Document, free of added material.  If you use the
9628     latter option, you must take reasonably prudent steps, when you
9629     begin distribution of Opaque copies in quantity, to ensure that
9630     this Transparent copy will remain thus accessible at the stated
9631     location until at least one year after the last time you
9632     distribute an Opaque copy (directly or through your agents or
9633     retailers) of that edition to the public.
9634
9635     It is requested, but not required, that you contact the authors of
9636     the Document well before redistributing any large number of
9637     copies, to give them a chance to provide you with an updated
9638     version of the Document.
9639
9640  4. MODIFICATIONS
9641
9642     You may copy and distribute a Modified Version of the Document
9643     under the conditions of sections 2 and 3 above, provided that you
9644     release the Modified Version under precisely this License, with
9645     the Modified Version filling the role of the Document, thus
9646     licensing distribution and modification of the Modified Version to
9647     whoever possesses a copy of it.  In addition, you must do these
9648     things in the Modified Version:
9649
9650       A. Use in the Title Page (and on the covers, if any) a title
9651          distinct from that of the Document, and from those of
9652          previous versions (which should, if there were any, be listed
9653          in the History section of the Document).  You may use the
9654          same title as a previous version if the original publisher of
9655          that version gives permission.
9656
9657       B. List on the Title Page, as authors, one or more persons or
9658          entities responsible for authorship of the modifications in
9659          the Modified Version, together with at least five of the
9660          principal authors of the Document (all of its principal
9661          authors, if it has fewer than five), unless they release you
9662          from this requirement.
9663
9664       C. State on the Title page the name of the publisher of the
9665          Modified Version, as the publisher.
9666
9667       D. Preserve all the copyright notices of the Document.
9668
9669       E. Add an appropriate copyright notice for your modifications
9670          adjacent to the other copyright notices.
9671
9672       F. Include, immediately after the copyright notices, a license
9673          notice giving the public permission to use the Modified
9674          Version under the terms of this License, in the form shown in
9675          the Addendum below.
9676
9677       G. Preserve in that license notice the full lists of Invariant
9678          Sections and required Cover Texts given in the Document's
9679          license notice.
9680
9681       H. Include an unaltered copy of this License.
9682
9683       I. Preserve the section Entitled "History", Preserve its Title,
9684          and add to it an item stating at least the title, year, new
9685          authors, and publisher of the Modified Version as given on
9686          the Title Page.  If there is no section Entitled "History" in
9687          the Document, create one stating the title, year, authors,
9688          and publisher of the Document as given on its Title Page,
9689          then add an item describing the Modified Version as stated in
9690          the previous sentence.
9691
9692       J. Preserve the network location, if any, given in the Document
9693          for public access to a Transparent copy of the Document, and
9694          likewise the network locations given in the Document for
9695          previous versions it was based on.  These may be placed in
9696          the "History" section.  You may omit a network location for a
9697          work that was published at least four years before the
9698          Document itself, or if the original publisher of the version
9699          it refers to gives permission.
9700
9701       K. For any section Entitled "Acknowledgements" or "Dedications",
9702          Preserve the Title of the section, and preserve in the
9703          section all the substance and tone of each of the contributor
9704          acknowledgements and/or dedications given therein.
9705
9706       L. Preserve all the Invariant Sections of the Document,
9707          unaltered in their text and in their titles.  Section numbers
9708          or the equivalent are not considered part of the section
9709          titles.
9710
9711       M. Delete any section Entitled "Endorsements".  Such a section
9712          may not be included in the Modified Version.
9713
9714       N. Do not retitle any existing section to be Entitled
9715          "Endorsements" or to conflict in title with any Invariant
9716          Section.
9717
9718       O. Preserve any Warranty Disclaimers.
9719
9720     If the Modified Version includes new front-matter sections or
9721     appendices that qualify as Secondary Sections and contain no
9722     material copied from the Document, you may at your option
9723     designate some or all of these sections as invariant.  To do this,
9724     add their titles to the list of Invariant Sections in the Modified
9725     Version's license notice.  These titles must be distinct from any
9726     other section titles.
9727
9728     You may add a section Entitled "Endorsements", provided it contains
9729     nothing but endorsements of your Modified Version by various
9730     parties--for example, statements of peer review or that the text
9731     has been approved by an organization as the authoritative
9732     definition of a standard.
9733
9734     You may add a passage of up to five words as a Front-Cover Text,
9735     and a passage of up to 25 words as a Back-Cover Text, to the end
9736     of the list of Cover Texts in the Modified Version.  Only one
9737     passage of Front-Cover Text and one of Back-Cover Text may be
9738     added by (or through arrangements made by) any one entity.  If the
9739     Document already includes a cover text for the same cover,
9740     previously added by you or by arrangement made by the same entity
9741     you are acting on behalf of, you may not add another; but you may
9742     replace the old one, on explicit permission from the previous
9743     publisher that added the old one.
9744
9745     The author(s) and publisher(s) of the Document do not by this
9746     License give permission to use their names for publicity for or to
9747     assert or imply endorsement of any Modified Version.
9748
9749  5. COMBINING DOCUMENTS
9750
9751     You may combine the Document with other documents released under
9752     this License, under the terms defined in section 4 above for
9753     modified versions, provided that you include in the combination
9754     all of the Invariant Sections of all of the original documents,
9755     unmodified, and list them all as Invariant Sections of your
9756     combined work in its license notice, and that you preserve all
9757     their Warranty Disclaimers.
9758
9759     The combined work need only contain one copy of this License, and
9760     multiple identical Invariant Sections may be replaced with a single
9761     copy.  If there are multiple Invariant Sections with the same name
9762     but different contents, make the title of each such section unique
9763     by adding at the end of it, in parentheses, the name of the
9764     original author or publisher of that section if known, or else a
9765     unique number.  Make the same adjustment to the section titles in
9766     the list of Invariant Sections in the license notice of the
9767     combined work.
9768
9769     In the combination, you must combine any sections Entitled
9770     "History" in the various original documents, forming one section
9771     Entitled "History"; likewise combine any sections Entitled
9772     "Acknowledgements", and any sections Entitled "Dedications".  You
9773     must delete all sections Entitled "Endorsements."
9774
9775  6. COLLECTIONS OF DOCUMENTS
9776
9777     You may make a collection consisting of the Document and other
9778     documents released under this License, and replace the individual
9779     copies of this License in the various documents with a single copy
9780     that is included in the collection, provided that you follow the
9781     rules of this License for verbatim copying of each of the
9782     documents in all other respects.
9783
9784     You may extract a single document from such a collection, and
9785     distribute it individually under this License, provided you insert
9786     a copy of this License into the extracted document, and follow
9787     this License in all other respects regarding verbatim copying of
9788     that document.
9789
9790  7. AGGREGATION WITH INDEPENDENT WORKS
9791
9792     A compilation of the Document or its derivatives with other
9793     separate and independent documents or works, in or on a volume of
9794     a storage or distribution medium, is called an "aggregate" if the
9795     copyright resulting from the compilation is not used to limit the
9796     legal rights of the compilation's users beyond what the individual
9797     works permit.  When the Document is included in an aggregate, this
9798     License does not apply to the other works in the aggregate which
9799     are not themselves derivative works of the Document.
9800
9801     If the Cover Text requirement of section 3 is applicable to these
9802     copies of the Document, then if the Document is less than one half
9803     of the entire aggregate, the Document's Cover Texts may be placed
9804     on covers that bracket the Document within the aggregate, or the
9805     electronic equivalent of covers if the Document is in electronic
9806     form.  Otherwise they must appear on printed covers that bracket
9807     the whole aggregate.
9808
9809  8. TRANSLATION
9810
9811     Translation is considered a kind of modification, so you may
9812     distribute translations of the Document under the terms of section
9813     4.  Replacing Invariant Sections with translations requires special
9814     permission from their copyright holders, but you may include
9815     translations of some or all Invariant Sections in addition to the
9816     original versions of these Invariant Sections.  You may include a
9817     translation of this License, and all the license notices in the
9818     Document, and any Warranty Disclaimers, provided that you also
9819     include the original English version of this License and the
9820     original versions of those notices and disclaimers.  In case of a
9821     disagreement between the translation and the original version of
9822     this License or a notice or disclaimer, the original version will
9823     prevail.
9824
9825     If a section in the Document is Entitled "Acknowledgements",
9826     "Dedications", or "History", the requirement (section 4) to
9827     Preserve its Title (section 1) will typically require changing the
9828     actual title.
9829
9830  9. TERMINATION
9831
9832     You may not copy, modify, sublicense, or distribute the Document
9833     except as expressly provided under this License.  Any attempt
9834     otherwise to copy, modify, sublicense, or distribute it is void,
9835     and will automatically terminate your rights under this License.
9836
9837     However, if you cease all violation of this License, then your
9838     license from a particular copyright holder is reinstated (a)
9839     provisionally, unless and until the copyright holder explicitly
9840     and finally terminates your license, and (b) permanently, if the
9841     copyright holder fails to notify you of the violation by some
9842     reasonable means prior to 60 days after the cessation.
9843
9844     Moreover, your license from a particular copyright holder is
9845     reinstated permanently if the copyright holder notifies you of the
9846     violation by some reasonable means, this is the first time you have
9847     received notice of violation of this License (for any work) from
9848     that copyright holder, and you cure the violation prior to 30 days
9849     after your receipt of the notice.
9850
9851     Termination of your rights under this section does not terminate
9852     the licenses of parties who have received copies or rights from
9853     you under this License.  If your rights have been terminated and
9854     not permanently reinstated, receipt of a copy of some or all of
9855     the same material does not give you any rights to use it.
9856
9857 10. FUTURE REVISIONS OF THIS LICENSE
9858
9859     The Free Software Foundation may publish new, revised versions of
9860     the GNU Free Documentation License from time to time.  Such new
9861     versions will be similar in spirit to the present version, but may
9862     differ in detail to address new problems or concerns.  See
9863     `http://www.gnu.org/copyleft/'.
9864
9865     Each version of the License is given a distinguishing version
9866     number.  If the Document specifies that a particular numbered
9867     version of this License "or any later version" applies to it, you
9868     have the option of following the terms and conditions either of
9869     that specified version or of any later version that has been
9870     published (not as a draft) by the Free Software Foundation.  If
9871     the Document does not specify a version number of this License,
9872     you may choose any version ever published (not as a draft) by the
9873     Free Software Foundation.  If the Document specifies that a proxy
9874     can decide which future versions of this License can be used, that
9875     proxy's public statement of acceptance of a version permanently
9876     authorizes you to choose that version for the Document.
9877
9878 11. RELICENSING
9879
9880     "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
9881     World Wide Web server that publishes copyrightable works and also
9882     provides prominent facilities for anybody to edit those works.  A
9883     public wiki that anybody can edit is an example of such a server.
9884     A "Massive Multiauthor Collaboration" (or "MMC") contained in the
9885     site means any set of copyrightable works thus published on the MMC
9886     site.
9887
9888     "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
9889     license published by Creative Commons Corporation, a not-for-profit
9890     corporation with a principal place of business in San Francisco,
9891     California, as well as future copyleft versions of that license
9892     published by that same organization.
9893
9894     "Incorporate" means to publish or republish a Document, in whole or
9895     in part, as part of another Document.
9896
9897     An MMC is "eligible for relicensing" if it is licensed under this
9898     License, and if all works that were first published under this
9899     License somewhere other than this MMC, and subsequently
9900     incorporated in whole or in part into the MMC, (1) had no cover
9901     texts or invariant sections, and (2) were thus incorporated prior
9902     to November 1, 2008.
9903
9904     The operator of an MMC Site may republish an MMC contained in the
9905     site under CC-BY-SA on the same site at any time before August 1,
9906     2009, provided the MMC is eligible for relicensing.

9909ADDENDUM: How to use this License for your documents
9910====================================================
9911
9912To use this License in a document you have written, include a copy of
9913the License in the document and put the following copyright and license
9914notices just after the title page:
9915
9916       Copyright (C)  YEAR  YOUR NAME.
9917       Permission is granted to copy, distribute and/or modify this document
9918       under the terms of the GNU Free Documentation License, Version 1.3
9919       or any later version published by the Free Software Foundation;
9920       with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
9921       Texts.  A copy of the license is included in the section entitled ``GNU
9922       Free Documentation License''.
9923
9924   If you have Invariant Sections, Front-Cover Texts and Back-Cover
9925Texts, replace the "with...Texts." line with this:
9926
9927         with the Invariant Sections being LIST THEIR TITLES, with
9928         the Front-Cover Texts being LIST, and with the Back-Cover Texts
9929         being LIST.
9930
9931   If you have Invariant Sections without Cover Texts, or some other
9932combination of the three, merge those two alternatives to suit the
9933situation.
9934
9935   If your document contains nontrivial examples of program code, we
9936recommend releasing these examples in parallel under your choice of
9937free software license, such as the GNU General Public License, to
9938permit their use in free software.
