46 1 Introduction
47 **************
49 BFD is a package which allows applications to use the same routines to
50 operate on object files whatever the object file format. A new object
51 file format can be supported simply by creating a new BFD back end and
52 adding it to the library.
54 BFD is split into two parts: the front end, and the back ends (one
55 for each object file format).
56 * The front end of BFD provides the interface to the user. It manages
57 memory and various canonical data structures. The front end also
58 decides which back end to use and when to call back end routines.
60 * The back ends provide BFD its view of the real world. Each back
61 end provides a set of calls which the BFD front end can use to
62 maintain its canonical form. The back ends also may keep around
63 information for their own use, for greater efficiency.

72 File: bfd.info, Node: History, Next: How It Works, Prev: Overview, Up: Overview
74 1.1 History
75 ===========
77 One spur behind BFD was the desire, on the part of the GNU 960 team at
78 Intel Oregon, for interoperability of applications on their COFF and
79 b.out file formats. Cygnus was providing GNU support for the team, and
80 was contracted to provide the required functionality.
82 The name came from a conversation David Wallace was having with
83 Richard Stallman about the library: RMS said that it would be quite
84 hard--David said "BFD". Stallman was right, but the name stuck.
86 At the same time, Ready Systems wanted much the same thing, but for
87 different object file formats: IEEE-695, Oasys, Srecords, a.out and 68k
88 coff.
90 BFD was first implemented by members of Cygnus Support; Steve
91 Chamberlain (`sac@cygnus.com'), John Gilmore (`gnu@cygnus.com'), K.
92 Richard Pixley (`rich@cygnus.com') and David Henkel-Wallace
93 (`gumby@cygnus.com').

96 File: bfd.info, Node: How It Works, Next: What BFD Version 2 Can Do, Prev: History, Up: Overview
98 1.2 How To Use BFD
99 ==================
101 To use the library, include `bfd.h' and link with `libbfd.a'.
103 BFD provides a common interface to the parts of an object file for a
104 calling application.
106 When an application successfully opens a target file (object,
107 archive, or whatever), a pointer to an internal structure is returned.
108 This pointer points to a structure called `bfd', described in `bfd.h'.
109 Our convention is to call this pointer a BFD, and instances of it
110 within code `abfd'. All operations on the target object file are
111 applied as methods to the BFD. The mapping is defined within `bfd.h'
112 in a set of macros, all beginning with `bfd_' to reduce namespace
113 pollution.
115 For example, this sequence does what you would probably expect:
116 return the number of sections in an object file attached to a BFD
117 `abfd'.
119 #include "bfd.h"
121 unsigned int number_of_sections (abfd)
122 bfd *abfd;
123 {
124 return bfd_count_sections (abfd);
125 }
127 The abstraction used within BFD is that an object file has:
129 * a header,
131 * a number of sections containing raw data (*note Sections::),
133 * a set of relocations (*note Relocations::), and
135 * some symbol information (*note Symbols::).
136 Also, BFDs opened for archives have the additional attribute of an
137 index and contain subordinate BFDs. This approach is fine for a.out and
138 coff, but loses efficiency when applied to formats such as S-records and
139 IEEE-695.
141 \x1f
142 File: bfd.info, Node: What BFD Version 2 Can Do, Prev: How It Works, Up: Overview
144 1.3 What BFD Version 2 Can Do
145 =============================
147 When an object file is opened, BFD subroutines automatically determine
148 the format of the input object file. They then build a descriptor in
149 memory with pointers to routines that will be used to access elements of
150 the object file's data structures.
152 As different information from the object files is required, BFD
153 reads from different sections of the file and processes them. For
154 example, a very common operation for the linker is processing symbol
155 tables. Each BFD back end provides a routine for converting between
156 the object file's representation of symbols and an internal canonical
157 format. When the linker asks for the symbol table of an object file, it
158 calls through a memory pointer to the routine from the relevant BFD
159 back end which reads and converts the table into a canonical form. The
160 linker then operates upon the canonical form. When the link is finished
161 and the linker writes the output file's symbol table, another BFD back
162 end routine is called to take the newly created symbol table and
163 convert it into the chosen output format.

171 File: bfd.info, Node: BFD information loss, Next: Canonical format, Up: What BFD Version 2 Can Do
173 1.3.1 Information Loss
174 ----------------------
176 _Information can be lost during output._ The output formats supported
177 by BFD do not provide identical facilities, and information which can
178 be described in one form has nowhere to go in another format. One
179 example of this is alignment information in `b.out'. There is nowhere
180 in an `a.out' format file to store alignment information on the
181 contained data, so when a file is linked from `b.out' and an `a.out'
182 image is produced, alignment information will not propagate to the
183 output file. (The linker will still use the alignment information
184 internally, so the link is performed correctly).
186 Another example is COFF section names. COFF files may contain an
187 unlimited number of sections, each one with a textual section name. If
188 the target of the link is a format which does not have many sections
189 (e.g., `a.out') or has sections without names (e.g., the Oasys format),
190 the link cannot be done simply. You can circumvent this problem by
191 describing the desired input-to-output section mapping with the linker
192 command language.
194 _Information can be lost during canonicalization._ The BFD internal
195 canonical form of the external formats is not exhaustive; there are
196 structures in input formats for which there is no direct representation
197 internally. This means that the BFD back ends cannot maintain all
198 possible data richness through the transformation between external to
199 internal and back to external formats.
201 This limitation is only a problem when an application reads one
202 format and writes another. Each BFD back end is responsible for
203 maintaining as much data as possible, and the internal BFD canonical
204 form has structures which are opaque to the BFD core, and exported only
205 to the back ends. When a file is read in one format, the canonical form
206 is generated for BFD and the application. At the same time, the back
207 end saves away any information which may otherwise be lost. If the data
208 is then written back in the same format, the back end routine will be
209 able to use the canonical form provided by the BFD core as well as the
210 information it prepared earlier. Since there is a great deal of
211 commonality between back ends, there is no information lost when
212 linking or copying big endian COFF to little endian COFF, or `a.out' to
213 `b.out'. When a mixture of formats is linked, the information is only
214 lost from the files whose format differs from the destination.
216 \x1f
217 File: bfd.info, Node: Canonical format, Prev: BFD information loss, Up: What BFD Version 2 Can Do
219 1.3.2 The BFD canonical object-file format
220 ------------------------------------------
222 The greatest potential for loss of information occurs when there is the
223 least overlap between the information provided by the source format,
224 that stored by the canonical format, and that needed by the destination
225 format. A brief description of the canonical form may help you
226 understand which kinds of data you can count on preserving across
227 conversions.
229 _files_
230 Information stored on a per-file basis includes target machine
231 architecture, particular implementation format type, a demand
232 pageable bit, and a write protected bit. Information like Unix
233 magic numbers is not stored here--only the magic numbers' meaning,
234 so a `ZMAGIC' file would have both the demand pageable bit and the
235 write protected text bit set. The byte order of the target is
236 stored on a per-file basis, so that big- and little-endian object
237 files may be used with one another.
239 _sections_
240 Each section in the input file contains the name of the section,
241 the section's original address in the object file, size and
242 alignment information, various flags, and pointers into other BFD
243 data structures.
245 _symbols_
246 Each symbol contains a pointer to the information for the object
247 file which originally defined it, its name, its value, and various
248 flag bits. When a BFD back end reads in a symbol table, it
249 relocates all symbols to make them relative to the base of the
250 section where they were defined. Doing this ensures that each
251 symbol points to its containing section. Each symbol also has a
252 varying amount of hidden private data for the BFD back end. Since
253 the symbol points to the original file, the private data format
254 for that symbol is accessible. `ld' can operate on a collection
255 of symbols of wildly different formats without problems.
257 Normal global and simple local symbols are maintained on output,
258 so an output file (no matter its format) will retain symbols
259 pointing to functions and to global, static, and common variables.
260 Some symbol information is not worth retaining; in `a.out', type
261 information is stored in the symbol table as long symbol names.
262 This information would be useless to most COFF debuggers; the
263 linker has command line switches to allow users to throw it away.
265 There is one word of type information within the symbol, so if the
266 format supports symbol type information within symbols (for
267 example, COFF, IEEE, Oasys) and the type is simple enough to fit
268 within one word (nearly everything but aggregates), the
269 information will be preserved.
271 _relocation level_
272 Each canonical BFD relocation record contains a pointer to the
273 symbol to relocate to, the offset of the data to relocate, the
274 section the data is in, and a pointer to a relocation type
275 descriptor. Relocation is performed by passing messages through
276 the relocation type descriptor and the symbol pointer. Therefore,
277 relocations can be performed on output data using a relocation
278 method that is only available in one of the input formats. For
279 instance, Oasys provides a byte relocation format. A relocation
280 record requesting this relocation type would point indirectly to a
281 routine to perform this, so the relocation may be performed on a
282 byte being written to a 68k COFF file, even though 68k COFF has no
283 such relocation type.
285 _line numbers_
286 Object formats can contain, for debugging purposes, some form of
287 mapping between symbols, source line numbers, and addresses in the
288 output file. These addresses have to be relocated along with the
289 symbol information. Each symbol with an associated list of line
290 number records points to the first record of the list. The head
291 of a line number list consists of a pointer to the symbol, which
292 allows finding out the address of the function whose line number
293 is being described. The rest of the list is made up of pairs:
294 offsets into the section and line numbers. Any format which can
295 simply derive this information can pass it successfully between
296 formats (COFF, IEEE and Oasys).

481 2.2 Error reporting
482 ===================
484 Most BFD functions return nonzero on success (check their individual
485 documentation for precise semantics). On an error, they call
486 `bfd_set_error' to set an error condition that callers can check by
487 calling `bfd_get_error'. If that returns `bfd_error_system_call', then
488 check `errno'.
490 The easiest way to report a BFD error to the user is to use
491 `bfd_perror'.
493 2.2.1 Type `bfd_error_type'
494 ---------------------------
496 The values returned by `bfd_get_error' are defined by the enumerated
497 type `bfd_error_type'.

616 associated with section SECT attached to bfd ABFD. If an error occurs,
617 return -1.
619 2.3.1.2 `bfd_canonicalize_reloc'
620 ................................
622 *Synopsis*
623 long bfd_canonicalize_reloc
624 (bfd *abfd, asection *sec, arelent **loc, asymbol **syms);
625 *Description*
626 Call the back end associated with the open BFD ABFD and translate the
627 external form of the relocation information attached to SEC into the
628 internal canonical form. Place the table into memory at LOC, which has
629 been preallocated, usually by a call to `bfd_get_reloc_upper_bound'.
630 Returns the number of relocs, or -1 on error.
632 The SYMS table is also needed for horrible internal magic reasons.
634 2.3.1.3 `bfd_set_reloc'
635 .......................
637 *Synopsis*
638 void bfd_set_reloc
639 (bfd *abfd, asection *sec, arelent **rel, unsigned int count);
640 *Description*
641 Set the relocation pointer and count within section SEC to the values
642 REL and COUNT. The argument ABFD is ignored.
644 2.3.1.4 `bfd_set_file_flags'
645 ............................
647 *Synopsis*
648 bfd_boolean bfd_set_file_flags (bfd *abfd, flagword flags);
649 *Description*
650 Set the flag word in the BFD ABFD to the value FLAGS.
652 Possible errors are:
653 * `bfd_error_wrong_format' - The target bfd was not of object format.
655 * `bfd_error_invalid_operation' - The target bfd was open for
656 reading.
658 * `bfd_error_invalid_operation' - The flag word contained a bit
659 which was not applicable to the type of file. E.g., an attempt
660 was made to set the `D_PAGED' bit on a BFD format which does not
661 support demand paging.
663 2.3.1.5 `bfd_get_arch_size'
664 ...........................
666 *Synopsis*
667 int bfd_get_arch_size (bfd *abfd);
668 *Description*
669 Returns the architecture address size, in bits, as determined by the
670 object file's format. For ELF, this information is included in the
671 header.
673 *Returns*
674 Returns the arch size in bits if known, `-1' otherwise.
676 2.3.1.6 `bfd_get_sign_extend_vma'
677 .................................
679 *Synopsis*
680 int bfd_get_sign_extend_vma (bfd *abfd);
681 *Description*
682 Indicates if the target architecture "naturally" sign extends an
683 address. Some architectures implicitly sign extend address values when
684 they are converted to types larger than the size of an address. For
685 instance, bfd_get_start_address() will return an address sign extended
686 to fill a bfd_vma when this is the case.
688 *Returns*
689 Returns `1' if the target architecture is known to sign extend
690 addresses, `0' if the target architecture is known to not sign extend
691 addresses, and `-1' otherwise.
693 2.3.1.7 `bfd_set_start_address'
694 ...............................
696 *Synopsis*
697 bfd_boolean bfd_set_start_address (bfd *abfd, bfd_vma vma);
698 *Description*
699 Make VMA the entry point of output BFD ABFD.
701 *Returns*
702 Returns `TRUE' on success, `FALSE' otherwise.
704 2.3.1.8 `bfd_get_gp_size'
705 .........................
707 *Synopsis*
708 unsigned int bfd_get_gp_size (bfd *abfd);
709 *Description*
710 Return the maximum size of objects to be optimized using the GP
711 register under MIPS ECOFF. This is typically set by the `-G' argument
712 to the compiler, assembler or linker.
714 2.3.1.9 `bfd_set_gp_size'
715 .........................
717 *Synopsis*
718 void bfd_set_gp_size (bfd *abfd, unsigned int i);
719 *Description*
720 Set the maximum size of objects to be optimized using the GP register
721 under ECOFF or MIPS ELF. This is typically set by the `-G' argument to
722 the compiler, assembler or linker.
724 2.3.1.10 `bfd_scan_vma'
725 .......................
727 *Synopsis*
728 bfd_vma bfd_scan_vma (const char *string, const char **end, int base);
729 *Description*
730 Convert, like `strtoul', a numerical expression STRING into a `bfd_vma'
731 integer, and return that integer. (Though without as many bells and
732 whistles as `strtoul'.) The expression is assumed to be unsigned
733 (i.e., positive). If given a BASE, it is used as the base for
734 conversion. A base of 0 causes the function to interpret the string in
735 hex if a leading "0x" or "0X" is found, otherwise in octal if a leading
736 zero is found, otherwise in decimal.
738 If the value would overflow, the maximum `bfd_vma' value is returned.
740 2.3.1.11 `bfd_copy_private_header_data'
741 .......................................
743 *Synopsis*
744 bfd_boolean bfd_copy_private_header_data (bfd *ibfd, bfd *obfd);
745 *Description*
746 Copy private BFD header information from the BFD IBFD to the the BFD
747 OBFD. This copies information that may require sections to exist, but
748 does not require symbol tables. Return `true' on success, `false' on
749 error. Possible error returns are:
751 * `bfd_error_no_memory' - Not enough memory exists to create private
752 data for OBFD.

901 ............................
903 *Synopsis*
904 bfd_boolean bfd_alt_mach_code (bfd *abfd, int alternative);
905 *Description*
906 When more than one machine code number is available for the same
907 machine type, this function can be used to switch between the preferred
908 one (alternative == 0) and any others. Currently, only ELF supports
909 this feature, with up to two alternate machine codes.

923 2.3.1.17 `bfd_preserve_save'
924 ............................
926 *Synopsis*
927 bfd_boolean bfd_preserve_save (bfd *, struct bfd_preserve *);
928 *Description*
929 When testing an object for compatibility with a particular target
930 back-end, the back-end object_p function needs to set up certain fields
931 in the bfd on successfully recognizing the object. This typically
932 happens in a piecemeal fashion, with failures possible at many points.
933 On failure, the bfd is supposed to be restored to its initial state,
934 which is virtually impossible. However, restoring a subset of the bfd
935 state works in practice. This function stores the subset and
936 reinitializes the bfd.
938 2.3.1.18 `bfd_preserve_restore'
939 ...............................
941 *Synopsis*
942 void bfd_preserve_restore (bfd *, struct bfd_preserve *);
943 *Description*
944 This function restores bfd state saved by bfd_preserve_save. If MARKER
945 is non-NULL in struct bfd_preserve then that block and all subsequently
946 bfd_alloc'd memory is freed.
948 2.3.1.19 `bfd_preserve_finish'
949 ..............................
951 *Synopsis*
952 void bfd_preserve_finish (bfd *, struct bfd_preserve *);
953 *Description*
954 This function should be called when the bfd state saved by
955 bfd_preserve_save is no longer needed. ie. when the back-end object_p
956 function returns with success.
958 2.3.1.20 `bfd_emul_get_maxpagesize'

976 for other formats.
978 2.3.1.22 `bfd_emul_get_commonpagesize'
979 ......................................
981 *Synopsis*

996 other formats.
998 2.3.1.24 `bfd_demangle'
999 .......................
1001 *Synopsis*
1002 char *bfd_demangle (bfd *, const char *, int);
1003 *Description*
1004 Wrapper around cplus_demangle. Strips leading underscores and other
1005 such chars that would otherwise confuse the demangler. If passed a g++
1006 v3 ABI mangled name, returns a buffer allocated with malloc holding the
1007 demangled name. Returns NULL otherwise and on memory alloc failure.
1009 2.3.1.25 `struct bfd_iovec'

1012 *Description*
1013 The `struct bfd_iovec' contains the internal file I/O class. Each
1014 `BFD' has an instance of this class and all file I/O is routed through
1015 it (it is assumed that the instance implements all methods listed
1016 below).
1017 struct bfd_iovec

1020 prefix is prepended to each method name. */

1030 file_ptr (*btell) (struct bfd *abfd);
1031 /* For the following, on successful completion a value of 0 is returned.
1032 Otherwise, a value of -1 is returned (and `bfd_error' is set). */
1033 int (*bseek) (struct bfd *abfd, file_ptr offset, int whence);
1034 int (*bclose) (struct bfd *abfd);
1035 int (*bflush) (struct bfd *abfd);
1036 int (*bstat) (struct bfd *abfd, struct stat *sb);
1037 };
1039 2.3.1.26 `bfd_get_mtime'
1040 ........................
1042 *Synopsis*
1043 long bfd_get_mtime (bfd *abfd);
1044 *Description*
1045 Return the file modification time (as read from the file system, or
1046 from the archive header for archive members).
1048 2.3.1.27 `bfd_get_size'
1049 .......................
1051 *Synopsis*
1052 file_ptr bfd_get_size (bfd *abfd);
1053 *Description*
1054 Return the file size (as read from file system) for the file associated
1055 with BFD ABFD.
1057 The initial motivation for, and use of, this routine is not so we
1058 can get the exact size of the object the BFD applies to, since that
1059 might not be generally possible (archive members for example). It
1060 would be ideal if someone could eventually modify it so that such
1061 results were guaranteed.
1063 Instead, we want to ask questions like "is this NNN byte sized
1064 object I'm about to try read from file offset YYY reasonable?" As as
1065 example of where we might do this, some object formats use string
1066 tables for which the first `sizeof (long)' bytes of the table contain
1067 the size of the table itself, including the size bytes. If an
1068 application tries to read what it thinks is one of these string tables,
1069 without some way to validate the size, and for some reason the size is
1070 wrong (byte swapping error, wrong location for the string table, etc.),
1071 the only clue is likely to be a read error when it tries to read the
1072 table, or a "virtual memory exhausted" error when it tries to allocate
1073 15 bazillon bytes of space for the 15 bazillon byte table it is about
1074 to read. This function at least allows us to answer the question, "is
1075 the size reasonable?".

1098 2.4 Memory Usage
1099 ================
1101 BFD keeps all of its internal structures in obstacks. There is one
1102 obstack per open BFD file, into which the current state is stored. When
1103 a BFD is closed, the obstack is deleted, and so everything which has
1104 been allocated by BFD for the closing file is thrown away.
1106 BFD does not free anything created by an application, but pointers
1107 into `bfd' structures become invalid on a `bfd_close'; for example,
1108 after a `bfd_close' the vector passed to `bfd_canonicalize_symtab' is
1109 still around, since it has been allocated by the application, but the
1110 data that it pointed to are lost.
1112 The general rule is to not close a BFD until all operations dependent
1113 upon data from the BFD have been completed, or all the data from within
1114 the file has been copied. To help with the management of memory, there
1115 is a function (`bfd_alloc_size') which returns the number of bytes in
1116 obstacks associated with the supplied BFD. This could be used to select
1117 the greediest open BFD, close it to reclaim the memory, perform some
1118 operation and reopen the BFD again, to get a fresh copy of the data
1119 structures.

1144 2.6 Sections
1145 ============
1147 The raw data contained within a BFD is maintained through the section
1148 abstraction. A single BFD may have any number of sections. It keeps
1149 hold of them by pointing to the first; each one points to the next in
1150 the list.
1152 Sections are supported in BFD in `section.c'.

1164 2.6.1 Section input
1165 -------------------
1167 When a BFD is opened for reading, the section structures are created
1168 and attached to the BFD.
1170 Each section has a name which describes the section in the outside
1171 world--for example, `a.out' would contain at least three sections,
1172 called `.text', `.data' and `.bss'.
1174 Names need not be unique; for example a COFF file may have several
1175 sections named `.data'.
1177 Sometimes a BFD will contain more than the "natural" number of
1178 sections. A back end may attach other sections containing constructor
1179 data, or an application may add a section (using `bfd_make_section') to
1180 the sections attached to an already open BFD. For example, the linker
1181 creates an extra section `COMMON' for each input file's BFD to hold
1182 information about common storage.
1184 The raw data is not necessarily read in when the section descriptor
1185 is created. Some targets may leave the data in place until a
1186 `bfd_get_section_contents' call is made. Other back ends may read in
1187 all the data at once. For example, an S-record file has to be read
1188 once to determine the size of the data. An IEEE-695 file doesn't
1189 contain raw data in sections, but data and relocation expressions
1190 intermixed, so the data area has to be parsed to get out the data and
1191 relocations.

1196 2.6.2 Section output
1197 --------------------
1199 To write a new object style BFD, the various sections to be written
1200 have to be created. They are attached to the BFD in the same way as
1201 input sections; data is written to the sections using
1202 `bfd_set_section_contents'.
1204 Any program that creates or combines sections (e.g., the assembler
1205 and linker) must use the `asection' fields `output_section' and
1206 `output_offset' to indicate the file sections to which each section
1207 must be written. (If the section is being created from scratch,
1208 `output_section' should probably point to the section itself and
1209 `output_offset' should probably be zero.)
1211 The data to be written comes from input sections attached (via
1212 `output_section' pointers) to the output sections. The output section
1213 structure can be considered a filter for the input section: the output
1214 section determines the vma of the output data and the name, but the
1215 input section determines the offset into the output section of the data
1216 to be written.
1218 E.g., to create a section "O", starting at 0x100, 0x123 long,
1219 containing two subsections, "A" at offset 0x0 (i.e., at vma 0x100) and
1220 "B" at offset 0x20 (i.e., at vma 0x120) the `asection' structures would
1221 look like:
1223 section name "A"
1224 output_offset 0x00
1225 size 0x20
1226 output_section -----------> section name "O"
1227 | vma 0x100
1228 section name "B" | size 0x123
1229 output_offset 0x20 |
1230 size 0x103 |
1231 output_section --------|
1233 2.6.3 Link orders
1234 -----------------
1236 The data within a section is stored in a "link_order". These are much
1237 like the fixups in `gas'. The link_order abstraction allows a section
1238 to grow and shrink within itself.
1240 A link_order knows how big it is, and which is the next link_order
1241 and where the raw data for it is; it also points to a list of
1242 relocations which apply to it.
1244 The link_order is used by the linker to perform relaxing on final
1245 code. The compiler creates code which is as big as necessary to make
1246 it work without relaxing, and the user can select whether to relax.
1247 Sometimes relaxing takes a lot of time. The linker runs around the
1248 relocations to see if any are attached to data which can be shrunk, if
1249 so it does it on a link_order by link_order basis.

1784 2.6.5 Section prototypes
1785 ------------------------
1787 These are the functions exported by the section handling part of BFD.
1789 2.6.5.1 `bfd_section_list_clear'
1790 ................................
1792 *Synopsis*
1793 void bfd_section_list_clear (bfd *);
1794 *Description*
1795 Clears the section list, and also resets the section count and hash
1796 table entries.
1798 2.6.5.2 `bfd_get_section_by_name'
1799 .................................
1801 *Synopsis*
1802 asection *bfd_get_section_by_name (bfd *abfd, const char *name);
1803 *Description*
1804 Run through ABFD and return the one of the `asection's whose name
1805 matches NAME, otherwise `NULL'. *Note Sections::, for more information.
1807 This should only be used in special cases; the normal way to process
1808 all sections of a given name is to use `bfd_map_over_sections' and
1809 `strcmp' on the name (or better yet, base it on the section flags or
1810 something else) for each section.
1812 2.6.5.3 `bfd_get_section_by_name_if'
1813 ....................................
1815 *Synopsis*
1816 asection *bfd_get_section_by_name_if
1817 (bfd *abfd,
1818 const char *name,
1819 bfd_boolean (*func) (bfd *abfd, asection *sect, void *obj),
1820 void *obj);
1821 *Description*
1822 Call the provided function FUNC for each section attached to the BFD
1823 ABFD whose name matches NAME, passing OBJ as an argument. The function
1824 will be called as if by
1826 func (abfd, the_section, obj);
1828 It returns the first section for which FUNC returns true, otherwise
1829 `NULL'.
1831 2.6.5.4 `bfd_get_unique_section_name'
1832 .....................................
1834 *Synopsis*
1835 char *bfd_get_unique_section_name
1836 (bfd *abfd, const char *templat, int *count);
1837 *Description*
1838 Invent a section name that is unique in ABFD by tacking a dot and a
1839 digit suffix onto the original TEMPLAT. If COUNT is non-NULL, then it
1840 specifies the first number tried as a suffix to generate a unique name.
1841 The value pointed to by COUNT will be incremented in this case.
1843 2.6.5.5 `bfd_make_section_old_way'
1844 ..................................
1846 *Synopsis*
1847 asection *bfd_make_section_old_way (bfd *abfd, const char *name);
1848 *Description*
1849 Create a new empty section called NAME and attach it to the end of the
1850 chain of sections for the BFD ABFD. An attempt to create a section with
1851 a name which is already in use returns its pointer without changing the
1852 section chain.
1854 It has the funny name since this is the way it used to be before it
1855 was rewritten....
1857 Possible errors are:
1858 * `bfd_error_invalid_operation' - If output has already started for
1859 this BFD.
1861 * `bfd_error_no_memory' - If memory allocation fails.
1863 2.6.5.6 `bfd_make_section_anyway_with_flags'
1864 ............................................
1866 *Synopsis*
1867 asection *bfd_make_section_anyway_with_flags
1868 (bfd *abfd, const char *name, flagword flags);
1869 *Description*
1870 Create a new empty section called NAME and attach it to the end of the
1871 chain of sections for ABFD. Create a new section even if there is
1872 already a section with that name. Also set the attributes of the new
1873 section to the value FLAGS.
1875 Return `NULL' and set `bfd_error' on error; possible errors are:
1876 * `bfd_error_invalid_operation' - If output has already started for
1877 ABFD.
1879 * `bfd_error_no_memory' - If memory allocation fails.
1881 2.6.5.7 `bfd_make_section_anyway'
1882 .................................
1884 *Synopsis*
1885 asection *bfd_make_section_anyway (bfd *abfd, const char *name);
1886 *Description*
1887 Create a new empty section called NAME and attach it to the end of the
1888 chain of sections for ABFD. Create a new section even if there is
1889 already a section with that name.
1891 Return `NULL' and set `bfd_error' on error; possible errors are:
1892 * `bfd_error_invalid_operation' - If output has already started for
1893 ABFD.
1895 * `bfd_error_no_memory' - If memory allocation fails.
1897 2.6.5.8 `bfd_make_section_with_flags'
1898 .....................................
1900 *Synopsis*
1901 asection *bfd_make_section_with_flags
1902 (bfd *, const char *name, flagword flags);
1903 *Description*
1904 Like `bfd_make_section_anyway', but return `NULL' (without calling
1905 bfd_set_error ()) without changing the section chain if there is
1906 already a section named NAME. Also set the attributes of the new
1907 section to the value FLAGS. If there is an error, return `NULL' and set
1908 `bfd_error'.
1910 2.6.5.9 `bfd_make_section'
1911 ..........................
1913 *Synopsis*
1914 asection *bfd_make_section (bfd *, const char *name);
1915 *Description*
1916 Like `bfd_make_section_anyway', but return `NULL' (without calling
1917 bfd_set_error ()) without changing the section chain if there is
1918 already a section named NAME. If there is an error, return `NULL' and
1919 set `bfd_error'.
1921 2.6.5.10 `bfd_set_section_flags'
1922 ................................
1924 *Synopsis*
1925 bfd_boolean bfd_set_section_flags
1926 (bfd *abfd, asection *sec, flagword flags);
1927 *Description*
1928 Set the attributes of the section SEC in the BFD ABFD to the value
1929 FLAGS. Return `TRUE' on success, `FALSE' on error. Possible error
1930 returns are:
1932 * `bfd_error_invalid_operation' - The section cannot have one or
1933 more of the attributes requested. For example, a .bss section in
1934 `a.out' may not have the `SEC_HAS_CONTENTS' field set.
1936 2.6.5.11 `bfd_map_over_sections'
1937 ................................
1939 *Synopsis*
1940 void bfd_map_over_sections
1941 (bfd *abfd,
1942 void (*func) (bfd *abfd, asection *sect, void *obj),
1943 void *obj);
1944 *Description*
1945 Call the provided function FUNC for each section attached to the BFD
1946 ABFD, passing OBJ as an argument. The function will be called as if by
1948 func (abfd, the_section, obj);
1950 This is the preferred method for iterating over sections; an
1951 alternative would be to use a loop:
1953 section *p;
1954 for (p = abfd->sections; p != NULL; p = p->next)
1955 func (abfd, p, ...)
1957 2.6.5.12 `bfd_sections_find_if'
1958 ...............................
1960 *Synopsis*
1961 asection *bfd_sections_find_if
1962 (bfd *abfd,
1963 bfd_boolean (*operation) (bfd *abfd, asection *sect, void *obj),
1964 void *obj);
1965 *Description*
1966 Call the provided function OPERATION for each section attached to the
1967 BFD ABFD, passing OBJ as an argument. The function will be called as if
1968 by
1970 operation (abfd, the_section, obj);
1972 It returns the first section for which OPERATION returns true.
1974 2.6.5.13 `bfd_set_section_size'
1975 ...............................
1977 *Synopsis*
1978 bfd_boolean bfd_set_section_size
1979 (bfd *abfd, asection *sec, bfd_size_type val);
1980 *Description*
1981 Set SEC to the size VAL. If the operation is ok, then `TRUE' is
1982 returned, else `FALSE'.
1984 Possible error returns:
1985 * `bfd_error_invalid_operation' - Writing has started to the BFD, so
1986 setting the size is invalid.
1988 2.6.5.14 `bfd_set_section_contents'
1989 ...................................
1991 *Synopsis*
1992 bfd_boolean bfd_set_section_contents
1993 (bfd *abfd, asection *section, const void *data,
1994 file_ptr offset, bfd_size_type count);
1995 *Description*
1996 Sets the contents of the section SECTION in BFD ABFD to the data
1997 starting in memory at DATA. The data is written to the output section
1998 starting at offset OFFSET for COUNT octets.
2000 Normally `TRUE' is returned, else `FALSE'. Possible error returns
2001 are:
2002 * `bfd_error_no_contents' - The output section does not have the
2003 `SEC_HAS_CONTENTS' attribute, so nothing can be written to it.
2005 * and some more too
2006 This routine is front end to the back end function
2007 `_bfd_set_section_contents'.
2009 2.6.5.15 `bfd_get_section_contents'
2010 ...................................
2012 *Synopsis*
2013 bfd_boolean bfd_get_section_contents
2014 (bfd *abfd, asection *section, void *location, file_ptr offset,
2015 bfd_size_type count);
2016 *Description*
2017 Read data from SECTION in BFD ABFD into memory starting at LOCATION.
2018 The data is read at an offset of OFFSET from the start of the input
2019 section, and is read for COUNT bytes.
2021 If the contents of a constructor with the `SEC_CONSTRUCTOR' flag set
2022 are requested or if the section does not have the `SEC_HAS_CONTENTS'
2023 flag set, then the LOCATION is filled with zeroes. If no errors occur,
2024 `TRUE' is returned, else `FALSE'.
2026 2.6.5.16 `bfd_malloc_and_get_section'
2027 .....................................
2029 *Synopsis*
2030 bfd_boolean bfd_malloc_and_get_section
2031 (bfd *abfd, asection *section, bfd_byte **buf);
2032 *Description*
2033 Read all data from SECTION in BFD ABFD into a buffer, *BUF, malloc'd by
2034 this function.
2036 2.6.5.17 `bfd_copy_private_section_data'

2040 bfd_boolean bfd_copy_private_section_data
2041 (bfd *ibfd, asection *isec, bfd *obfd, asection *osec);
2042 *Description*
2043 Copy private section information from ISEC in the BFD IBFD to the
2044 section OSEC in the BFD OBFD. Return `TRUE' on success, `FALSE' on
2045 error. Possible error returns are:
2047 * `bfd_error_no_memory' - Not enough memory exists to create private
2048 data for OSEC.

2073 2.7 Symbols
2074 ===========
2076 BFD tries to maintain as much symbol information as it can when it
2077 moves information from file to file. BFD passes information to
2078 applications though the `asymbol' structure. When the application
2079 requests the symbol table, BFD reads the table in the native form and
2080 translates parts of it into the internal format. To maintain more than
2081 the information passed to applications, some targets keep some
2082 information "behind the scenes" in a structure only the particular back
2083 end knows about. For example, the coff back end keeps the original
2084 symbol table structure as well as the canonical structure when a BFD is
2085 read in. On output, the coff back end can reconstruct the output symbol
2086 table so that no information is lost, even information unique to coff
2087 which BFD doesn't know or understand. If a coff symbol table were read,
2088 but were written through an a.out back end, all the coff specific
2089 information would be lost. The symbol table of a BFD is not necessarily
2090 read in until a canonicalize request is made. Then the BFD back end
2091 fills in a table provided by the application with pointers to the
2092 canonical information. To output symbols, the application provides BFD
2093 with a table of pointers to pointers to `asymbol's. This allows
2094 applications like the linker to output a symbol as it was read, since
2095 the "behind the scenes" information will be still available.

2108 2.7.1 Reading symbols
2109 ---------------------
2111 There are two stages to reading a symbol table from a BFD: allocating
2112 storage, and the actual reading process. This is an excerpt from an
2113 application which reads the symbol table:
2115 long storage_needed;
2116 asymbol **symbol_table;
2117 long number_of_symbols;
2118 long i;
2120 storage_needed = bfd_get_symtab_upper_bound (abfd);
2122 if (storage_needed < 0)
2123 FAIL
2125 if (storage_needed == 0)
2126 return;
2128 symbol_table = xmalloc (storage_needed);
2129 ...
2130 number_of_symbols =
2131 bfd_canonicalize_symtab (abfd, symbol_table);
2133 if (number_of_symbols < 0)
2134 FAIL
2136 for (i = 0; i < number_of_symbols; i++)
2137 process_symbol (symbol_table[i]);
2139 All storage for the symbols themselves is in an objalloc connected
2140 to the BFD; it is freed when the BFD is closed.
2142 \x1f
2143 File: bfd.info, Node: Writing Symbols, Next: Mini Symbols, Prev: Reading Symbols, Up: Symbols
2145 2.7.2 Writing symbols
2146 ---------------------
2148 Writing of a symbol table is automatic when a BFD open for writing is
2149 closed. The application attaches a vector of pointers to pointers to
2150 symbols to the BFD being written, and fills in the symbol count. The
2151 close and cleanup code reads through the table provided and performs
2152 all the necessary operations. The BFD output code must always be
2153 provided with an "owned" symbol: one which has come from another BFD,
2154 or one which has been created using `bfd_make_empty_symbol'. Here is an
2155 example showing the creation of a symbol table with only one element:
2157 #include "bfd.h"
2158 int main (void)
2159 {
2160 bfd *abfd;
2161 asymbol *ptrs[2];
2162 asymbol *new;
2164 abfd = bfd_openw ("foo","a.out-sunos-big");
2165 bfd_set_format (abfd, bfd_object);
2166 new = bfd_make_empty_symbol (abfd);
2167 new->name = "dummy_symbol";
2168 new->section = bfd_make_section_old_way (abfd, ".text");
2169 new->flags = BSF_GLOBAL;
2170 new->value = 0x12345;
2172 ptrs[0] = new;
2173 ptrs[1] = 0;
2175 bfd_set_symtab (abfd, ptrs, 1);
2176 bfd_close (abfd);
2177 return 0;
2178 }
2180 ./makesym
2181 nm foo
2182 00012345 A dummy_symbol
2184 Many formats cannot represent arbitrary symbol information; for
2185 instance, the `a.out' object format does not allow an arbitrary number
2186 of sections. A symbol pointing to a section which is not one of
2187 `.text', `.data' or `.bss' cannot be described.
2189 \x1f
2190 File: bfd.info, Node: Mini Symbols, Next: typedef asymbol, Prev: Writing Symbols, Up: Symbols
2192 2.7.3 Mini Symbols
2193 ------------------
2195 Mini symbols provide read-only access to the symbol table. They use
2196 less memory space, but require more time to access. They can be useful
2197 for tools like nm or objdump, which may have to handle symbol tables of
2198 extremely large executables.
2200 The `bfd_read_minisymbols' function will read the symbols into
2201 memory in an internal form. It will return a `void *' pointer to a
2202 block of memory, a symbol count, and the size of each symbol. The
2203 pointer is allocated using `malloc', and should be freed by the caller
2204 when it is no longer needed.
2206 The function `bfd_minisymbol_to_symbol' will take a pointer to a
2207 minisymbol, and a pointer to a structure returned by
2208 `bfd_make_empty_symbol', and return a `asymbol' structure. The return
2209 value may or may not be the same as the value from
2210 `bfd_make_empty_symbol' which was passed in.

2515 2.8 Archives
2516 ============
2518 *Description*
2519 An archive (or library) is just another BFD. It has a symbol table,
2520 although there's not much a user program will do with it.
2522 The big difference between an archive BFD and an ordinary BFD is
2523 that the archive doesn't have sections. Instead it has a chain of BFDs
2524 that are considered its contents. These BFDs can be manipulated like
2525 any other. The BFDs contained in an archive opened for reading will
2526 all be opened for reading. You may put either input or output BFDs
2527 into an archive opened for output; they will be handled correctly when
2528 the archive is closed.
2530 Use `bfd_openr_next_archived_file' to step through the contents of
2531 an archive opened for input. You don't have to read the entire archive
2532 if you don't want to! Read it until you find what you want.
2534 Archive contents of output BFDs are chained through the `next'
2535 pointer in a BFD. The first one is findable through the `archive_head'
2536 slot of the archive. Set it with `bfd_set_archive_head' (q.v.). A
2537 given BFD may be in only one open output archive at a time.
2539 As expected, the BFD archive code is more general than the archive
2540 code of any given environment. BFD archives may contain files of
2541 different formats (e.g., a.out and coff) and even different
2542 architectures. You may even place archives recursively into archives!
2544 This can cause unexpected confusion, since some archive formats are
2545 more expressive than others. For instance, Intel COFF archives can
2546 preserve long filenames; SunOS a.out archives cannot. If you move a
2547 file from the first to the second format and back again, the filename
2548 may be truncated. Likewise, different a.out environments have different
2549 conventions as to how they truncate filenames, whether they preserve
2550 directory names in filenames, etc. When interoperating with native
2551 tools, be sure your files are homogeneous.
2553 Beware: most of these formats do not react well to the presence of
2554 spaces in filenames. We do the best we can, but can't always handle
2555 this case due to restrictions in the format of archives. Many Unix
2556 utilities are braindead in regards to spaces and such in filenames
2557 anyway, so this shouldn't be much of a restriction.
2559 Archives are supported in BFD in `archive.c'.

2571 Step through archive ABFD's symbol table (if it has one). Successively
2572 update SYM with the next symbol's information, returning that symbol's
2573 (internal) index into the symbol table.
2575 Supply `BFD_NO_MORE_SYMBOLS' as the PREVIOUS entry to get the first
2576 one; returns `BFD_NO_MORE_SYMBOLS' when you've already got the last one.
2578 A `carsym' is a canonical archive symbol. The only user-visible
2579 element is its name, a null-terminated string.

2597 BFD on the first contained element and returns that. Subsequent calls
2598 should pass the archive and the previous return value to return a
2599 created BFD to the next contained element. NULL is returned when there
2600 are no more.

2605 2.9 File formats
2606 ================
2608 A format is a BFD concept of high level file contents type. The formats
2609 supported by BFD are:
2611 * `bfd_object'
2612 The BFD may contain data, symbols, relocations and debug info.
2614 * `bfd_archive'
2615 The BFD contains other BFDs and an optional index.
2617 * `bfd_core'
2618 The BFD contains the result of an executable core dump.
2620 2.9.1 File format functions
2621 ---------------------------
2623 2.9.1.1 `bfd_check_format'
2624 ..........................
2626 *Synopsis*
2627 bfd_boolean bfd_check_format (bfd *abfd, bfd_format format);
2628 *Description*
2629 Verify if the file attached to the BFD ABFD is compatible with the
2630 format FORMAT (i.e., one of `bfd_object', `bfd_archive' or `bfd_core').
2632 If the BFD has been set to a specific target before the call, only
2633 the named target and format combination is checked. If the target has
2634 not been set, or has been set to `default', then all the known target
2635 backends is interrogated to determine a match. If the default target
2636 matches, it is used. If not, exactly one target must recognize the
2637 file, or an error results.
2639 The function returns `TRUE' on success, otherwise `FALSE' with one
2640 of the following error codes:
2642 * `bfd_error_invalid_operation' - if `format' is not one of
2643 `bfd_object', `bfd_archive' or `bfd_core'.
2645 * `bfd_error_system_call' - if an error occured during a read - even
2646 some file mismatches can cause bfd_error_system_calls.
2648 * `file_not_recognised' - none of the backends recognised the file
2649 format.
2651 * `bfd_error_file_ambiguously_recognized' - more than one backend
2652 recognised the file format.
2654 2.9.1.2 `bfd_check_format_matches'
2655 ..................................
2657 *Synopsis*
2658 bfd_boolean bfd_check_format_matches
2659 (bfd *abfd, bfd_format format, char ***matching);
2660 *Description*
2661 Like `bfd_check_format', except when it returns FALSE with `bfd_errno'
2662 set to `bfd_error_file_ambiguously_recognized'. In that case, if
2663 MATCHING is not NULL, it will be filled in with a NULL-terminated list
2664 of the names of the formats that matched, allocated with `malloc'.
2665 Then the user may choose a format and try again.
2667 When done with the list that MATCHING points to, the caller should
2668 free it.
2670 2.9.1.3 `bfd_set_format'
2671 ........................
2673 *Synopsis*
2674 bfd_boolean bfd_set_format (bfd *abfd, bfd_format format);
2675 *Description*
2676 This function sets the file format of the BFD ABFD to the format
2677 FORMAT. If the target set in the BFD does not support the format
2678 requested, the format is invalid, or the BFD is not open for writing,
2679 then an error occurs.
2681 2.9.1.4 `bfd_format_string'
2682 ...........................
2684 *Synopsis*
2685 const char *bfd_format_string (bfd_format format);
2686 *Description*
2687 Return a pointer to a const string `invalid', `object', `archive',
2688 `core', or `unknown', depending upon the value of FORMAT.

2693 2.10 Relocations
2694 ================
2696 BFD maintains relocations in much the same way it maintains symbols:
2697 they are left alone until required, then read in en-masse and
2698 translated into an internal form. A common routine
2699 `bfd_perform_relocation' acts upon the canonical form to do the fixup.
2701 Relocations are maintained on a per section basis, while symbols are
2702 maintained on a per BFD basis.
2704 All that a back end has to do to fit the BFD interface is to create
2705 a `struct reloc_cache_entry' for each relocation in a particular
2706 section, and fill in the right bits of the structures.

2768 }
2769 arelent;
2770 *Description*
2771 Here is a description of each of the fields within an `arelent':
2773 * `sym_ptr_ptr'
2774 The symbol table pointer points to a pointer to the symbol
2775 associated with the relocation request. It is the pointer into the
2776 table returned by the back end's `canonicalize_symtab' action. *Note
2777 Symbols::. The symbol is referenced through a pointer to a pointer so
2778 that tools like the linker can fix up all the symbols of the same name
2779 by modifying only one pointer. The relocation routine looks in the
2780 symbol and uses the base of the section the symbol is attached to and
2781 the value of the symbol as the initial relocation offset. If the symbol
2782 pointer is zero, then the section provided is looked up.
2784 * `address'
2785 The `address' field gives the offset in bytes from the base of the
2786 section data which owns the relocation record to the first byte of
2787 relocatable information. The actual data relocated will be relative to
2788 this point; for example, a relocation type which modifies the bottom
2789 two bytes of a four byte word would not touch the first byte pointed to
2790 in a big endian world.
2792 * `addend'
2793 The `addend' is a value provided by the back end to be added (!) to
2794 the relocation offset. Its interpretation is dependent upon the howto.
2795 For example, on the 68k the code:
2797 char foo[];
2798 main()
2799 {
2800 return foo[0x12345678];
2801 }
2803 Could be compiled into:
2805 linkw fp,#-4
2806 moveb @#12345678,d0
2807 extbl d0
2808 unlk fp
2809 rts
2811 This could create a reloc pointing to `foo', but leave the offset in
2812 the data, something like:
2814 RELOCATION RECORDS FOR [.text]:
2815 offset type value
2816 00000006 32 _foo
2818 00000000 4e56 fffc ; linkw fp,#-4
2819 00000004 1039 1234 5678 ; moveb @#12345678,d0
2820 0000000a 49c0 ; extbl d0
2821 0000000c 4e5e ; unlk fp
2822 0000000e 4e75 ; rts
2824 Using coff and an 88k, some instructions don't have enough space in
2825 them to represent the full address range, and pointers have to be
2826 loaded in two parts. So you'd get something like:
2828 or.u r13,r0,hi16(_foo+0x12345678)
2829 ld.b r2,r13,lo16(_foo+0x12345678)
2830 jmp r1
2832 This should create two relocs, both pointing to `_foo', and with
2833 0x12340000 in their addend field. The data would consist of:
2835 RELOCATION RECORDS FOR [.text]:
2836 offset type value
2837 00000002 HVRT16 _foo+0x12340000
2838 00000006 LVRT16 _foo+0x12340000
2840 00000000 5da05678 ; or.u r13,r0,0x5678
2841 00000004 1c4d5678 ; ld.b r2,r13,0x5678
2842 00000008 f400c001 ; jmp r1
2844 The relocation routine digs out the value from the data, adds it to
2845 the addend to get the original offset, and then adds the value of
2846 `_foo'. Note that all 32 bits have to be kept around somewhere, to cope
2847 with carry from bit 15 to bit 16.
2849 One further example is the sparc and the a.out format. The sparc has
2850 a similar problem to the 88k, in that some instructions don't have room
2851 for an entire offset, but on the sparc the parts are created in odd
2852 sized lumps. The designers of the a.out format chose to not use the
2853 data within the section for storing part of the offset; all the offset
2854 is kept within the reloc. Anything in the data should be ignored.
2856 save %sp,-112,%sp
2857 sethi %hi(_foo+0x12345678),%g2
2858 ldsb [%g2+%lo(_foo+0x12345678)],%i0
2859 ret
2860 restore
2862 Both relocs contain a pointer to `foo', and the offsets contain junk.
2864 RELOCATION RECORDS FOR [.text]:
2865 offset type value
2866 00000004 HI22 _foo+0x12345678

2875 * `howto'
2876 The `howto' field can be imagined as a relocation instruction. It is
2877 a pointer to a structure which contains information on what to do with
2878 all of the other information in the reloc record and data section. A
2879 back end would normally have a relocation instruction set and turn
2880 relocations into pointers to the correct structure on input - but it
2881 would be possible to create each howto field on demand.

3090 char **error_message);
3091 *Description*
3092 If OUTPUT_BFD is supplied to this function, the generated image will be
3093 relocatable; the relocations are copied to the output file after they
3094 have been changed to reflect the new state of the world. There are two
3095 ways of reflecting the results of partial linkage in an output file: by
3096 modifying the output data in place, and by modifying the relocation
3097 record. Some native formats (e.g., basic a.out and basic coff) have no
3098 way of specifying an addend in the relocation type, so the addend has
3099 to go in the output data. This is no big deal since in these formats
3100 the output data slot will always be big enough for the addend. Complex
3101 reloc types with addends were invented to solve just this problem. The
3102 ERROR_MESSAGE argument is set to an error message if this return
3103 `bfd_reloc_dangerous'.

3115 *Description*
3116 This looks remarkably like `bfd_perform_relocation', except it does not
3117 expect that the section contents have been filled in. I.e., it's
3118 suitable for use when creating, rather than applying a relocation.
3120 For now, this function should be considered reserved for the
3121 assembler.

3126 2.10.2 The howto manager
3127 ------------------------
3129 When an application wants to create a relocation, but doesn't know what
3130 the target machine might call it, it can find out by using this bit of
3131 code.
3133 2.10.2.1 `bfd_reloc_code_type'
3134 ..............................
3136 *Description*
3137 The insides of a reloc code. The idea is that, eventually, there will
3138 be one enumerator for every type of relocation we ever do. Pass one of
3139 these values to `bfd_reloc_type_lookup', and it'll return a howto
3140 pointer.
3142 This does mean that the application must determine the correct
3143 enumerator value; you can't get a howto pointer from a random set of
3144 attributes.
3146 Here are the possible values for `enum bfd_reloc_code_real':
3148 -- : BFD_RELOC_64
3149 -- : BFD_RELOC_32
3150 -- : BFD_RELOC_26
3151 -- : BFD_RELOC_24
3152 -- : BFD_RELOC_16
3153 -- : BFD_RELOC_14

3160 -- : BFD_RELOC_16_PCREL
3161 -- : BFD_RELOC_12_PCREL
3162 -- : BFD_RELOC_8_PCREL
3163 PC-relative relocations. Sometimes these are relative to the
3164 address of the relocation itself; sometimes they are relative to
3165 the start of the section containing the relocation. It depends on
3166 the specific target.
3168 The 24-bit relocation is used in some Intel 960 configurations.
3170 -- : BFD_RELOC_32_SECREL
3171 Section relative relocations. Some targets need this for DWARF2.

3196 -- : BFD_RELOC_68K_GLOB_DAT
3197 -- : BFD_RELOC_68K_JMP_SLOT
3198 -- : BFD_RELOC_68K_RELATIVE
3199 Relocations used by 68K ELF.

3205 -- : BFD_RELOC_HI16_S_BASEREL
3206 -- : BFD_RELOC_8_BASEREL
3207 -- : BFD_RELOC_RVA
3208 Linkage-table relative.
3210 -- : BFD_RELOC_8_FFnn
3211 Absolute 8-bit relocation, but used to form an address like 0xFFnn.
3213 -- : BFD_RELOC_32_PCREL_S2
3214 -- : BFD_RELOC_16_PCREL_S2
3215 -- : BFD_RELOC_23_PCREL_S2
3216 These PC-relative relocations are stored as word displacements -
3217 i.e., byte displacements shifted right two bits. The 30-bit word
3218 displacement (<<32_PCREL_S2>> - 32 bits, shifted 2) is used on the
3219 SPARC. (SPARC tools generally refer to this as <<WDISP30>>.) The
3220 signed 16-bit displacement is used on the MIPS, and the 23-bit
3221 displacement is used on the Alpha.
3223 -- : BFD_RELOC_HI22
3224 -- : BFD_RELOC_LO10
3225 High 22 bits and low 10 bits of 32-bit value, placed into lower
3226 bits of the target word. These are used on the SPARC.
3228 -- : BFD_RELOC_GPREL16
3229 -- : BFD_RELOC_GPREL32
3230 For systems that allocate a Global Pointer register, these are
3231 displacements off that register. These relocation types are
3232 handled specially, because the value the register will have is
3233 decided relatively late.
3235 -- : BFD_RELOC_I960_CALLJ
3236 Reloc types used for i960/b.out.

3333 -- : BFD_RELOC_ALPHA_GPDISP_HI16
3334 Alpha ECOFF and ELF relocations. Some of these treat the symbol or
3335 "addend" in some special way. For GPDISP_HI16 ("gpdisp")
3336 relocations, the symbol is ignored when writing; when reading, it
3337 will be the absolute section symbol. The addend is the
3338 displacement in bytes of the "lda" instruction from the "ldah"
3339 instruction (which is at the address of this reloc).
3341 -- : BFD_RELOC_ALPHA_GPDISP_LO16
3342 For GPDISP_LO16 ("ignore") relocations, the symbol is handled as
3343 with GPDISP_HI16 relocs. The addend is ignored when writing the
3344 relocations out, and is filled in with the file's GP value on
3345 reading, for convenience.
3347 -- : BFD_RELOC_ALPHA_GPDISP
3348 The ELF GPDISP relocation is exactly the same as the GPDISP_HI16
3349 relocation except that there is no accompanying GPDISP_LO16
3350 relocation.
3352 -- : BFD_RELOC_ALPHA_LITERAL
3353 -- : BFD_RELOC_ALPHA_ELF_LITERAL
3354 -- : BFD_RELOC_ALPHA_LITUSE
3355 The Alpha LITERAL/LITUSE relocs are produced by a symbol reference;
3356 the assembler turns it into a LDQ instruction to load the address
3357 of the symbol, and then fills in a register in the real
3358 instruction.
3360 The LITERAL reloc, at the LDQ instruction, refers to the .lita
3361 section symbol. The addend is ignored when writing, but is filled
3362 in with the file's GP value on reading, for convenience, as with
3363 the GPDISP_LO16 reloc.
3365 The ELF_LITERAL reloc is somewhere between 16_GOTOFF and
3366 GPDISP_LO16. It should refer to the symbol to be referenced, as
3367 with 16_GOTOFF, but it generates output not based on the position
3368 within the .got section, but relative to the GP value chosen for
3369 the file during the final link stage.
3371 The LITUSE reloc, on the instruction using the loaded address,
3372 gives information to the linker that it might be able to use to
3373 optimize away some literal section references. The symbol is
3374 ignored (read as the absolute section symbol), and the "addend"
3375 indicates the type of instruction using the register: 1 - "memory"
3376 fmt insn 2 - byte-manipulation (byte offset reg) 3 - jsr (target
3377 of branch)
3379 -- : BFD_RELOC_ALPHA_HINT
3380 The HINT relocation indicates a value that should be filled into
3381 the "hint" field of a jmp/jsr/ret instruction, for possible branch-
3382 prediction logic which may be provided on some processors.
3384 -- : BFD_RELOC_ALPHA_LINKAGE
3385 The LINKAGE relocation outputs a linkage pair in the object file,
3386 which is filled by the linker.
3388 -- : BFD_RELOC_ALPHA_CODEADDR
3389 The CODEADDR relocation outputs a STO_CA in the object file, which
3390 is filled by the linker.

3393 -- : BFD_RELOC_ALPHA_GPREL_LO16
3394 The GPREL_HI/LO relocations together form a 32-bit offset from the
3395 GP register.
3397 -- : BFD_RELOC_ALPHA_BRSGP
3398 Like BFD_RELOC_23_PCREL_S2, except that the source and target must

4728 When the -gc-sections option is given, the linker will zero out
4729 the entries that are not used, so that the code for those
4730 functions need not be included in the output.
4732 VTABLE_INHERIT is a zero-space relocation used to describe to the
4733 linker the inheritance tree of a C++ virtual function table. The
4734 relocation's symbol should be the parent class' vtable, and the
4735 relocation should be located at the child vtable.
4737 VTABLE_ENTRY is a zero-space relocation that describes the use of a
4738 virtual function table entry. The reloc's symbol should refer to
4739 the table of the class mentioned in the code. Off of that base,
4740 an offset describes the entry that is being used. For Rela hosts,
4741 this offset is stored in the reloc's addend. For Rel hosts, we
4742 are forced to put this offset in the reloc's section offset.

5330 2.12 Targets
5331 ============
5333 *Description*
5334 Each port of BFD to a different machine requires the creation of a
5335 target back end. All the back end provides to the root part of BFD is a
5336 structure containing pointers to functions which perform certain low
5337 level operations on files. BFD translates the applications's requests
5338 through a pointer into calls to the back end routines.
5340 When a file is opened with `bfd_openr', its format and target are
5341 unknown. BFD uses various mechanisms to determine how to interpret the
5342 file. The operations performed are:
5344 * Create a BFD by calling the internal routine `_bfd_new_bfd', then
5345 call `bfd_find_target' with the target string supplied to
5346 `bfd_openr' and the new BFD pointer.
5348 * If a null target string was provided to `bfd_find_target', look up
5349 the environment variable `GNUTARGET' and use that as the target
5350 string.
5352 * If the target string is still `NULL', or the target string is
5353 `default', then use the first item in the target vector as the
5354 target type, and set `target_defaulted' in the BFD to cause
5355 `bfd_check_format' to loop through all the targets. *Note
5356 bfd_target::. *Note Formats::.
5358 * Otherwise, inspect the elements in the target vector one by one,
5359 until a match on target name is found. When found, use it.
5361 * Otherwise return the error `bfd_error_invalid_target' to
5362 `bfd_openr'.
5364 * `bfd_openr' attempts to open the file using `bfd_open_file', and
5365 returns the BFD.
5366 Once the BFD has been opened and the target selected, the file
5367 format may be determined. This is done by calling `bfd_check_format' on
5368 the BFD with a suggested format. If `target_defaulted' has been set,
5369 each possible target type is tried to see if it recognizes the
5370 specified format. `bfd_check_format' returns `TRUE' when the caller
5371 guesses right.

5380 2.12.1 bfd_target
5381 -----------------
5383 *Description*
5384 This structure contains everything that BFD knows about a target. It
5385 includes things like its byte order, name, and which routines to call
5386 to do various operations.
5388 Every BFD points to a target structure with its `xvec' member.
5390 The macros below are used to dispatch to functions through the
5391 `bfd_target' vector. They are used in a number of macros further down
5392 in `bfd.h', and are also used when calling various routines by hand
5393 inside the BFD implementation. The ARGLIST argument must be
5394 parenthesized; it contains all the arguments to the called function.
5396 They make the documentation (more) unpleasant to read, so if someone
5397 wants to fix this and not break the above, please do.
5398 #define BFD_SEND(bfd, message, arglist) \
5399 ((*((bfd)->xvec->message)) arglist)
5401 #ifdef DEBUG_BFD_SEND
5402 #undef BFD_SEND
5403 #define BFD_SEND(bfd, message, arglist) \
5404 (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
5405 ((*((bfd)->xvec->message)) arglist) : \
5406 (bfd_assert (__FILE__,__LINE__), NULL))
5407 #endif
5408 For operations which index on the BFD format:
5409 #define BFD_SEND_FMT(bfd, message, arglist) \
5410 (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist)
5412 #ifdef DEBUG_BFD_SEND
5413 #undef BFD_SEND_FMT
5414 #define BFD_SEND_FMT(bfd, message, arglist) \
5415 (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
5416 (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist) : \
5417 (bfd_assert (__FILE__,__LINE__), NULL))
5418 #endif
5419 This is the structure which defines the type of BFD this is. The
5420 `xvec' member of the struct `bfd' itself points here. Each module that
5421 implements access to a different target under BFD, defines one of these.
5423 FIXME, these names should be rationalised with the names of the
5424 entry points which call them. Too bad we can't have one macro to define
5425 them both!

5811 *Description*
5812 Set the default target vector to use when recognizing a BFD. This
5813 takes the name of the target, which may be a BFD target name or a
5814 configuration triplet.

5817 ..........................
5819 *Synopsis*
5820 const bfd_target *bfd_find_target (const char *target_name, bfd *abfd);
5821 *Description*
5822 Return a pointer to the transfer vector for the object target named
5823 TARGET_NAME. If TARGET_NAME is `NULL', choose the one in the
5824 environment variable `GNUTARGET'; if that is null or not defined, then
5825 choose the first entry in the target list. Passing in the string
5826 "default" or setting the environment variable to "default" will cause
5827 the first entry in the target list to be returned, and
5828 "target_defaulted" will be set in the BFD if ABFD isn't `NULL'. This
5829 causes `bfd_check_format' to loop over all the targets to find the one
5830 that matches the file being read.

5848 *Description*
5849 Return a pointer to the first transfer vector in the list of transfer
5850 vectors maintained by BFD that produces a non-zero result when passed
5851 to the function SEARCH_FUNC. The parameter DATA is passed, unexamined,
5852 to the search function.

5857 2.13 Architectures
5858 ==================
5860 BFD keeps one atom in a BFD describing the architecture of the data
5861 attached to the BFD: a pointer to a `bfd_arch_info_type'.
5863 Pointers to structures can be requested independently of a BFD so
5864 that an architecture's information can be interrogated without access
5865 to an open BFD.
5867 The architecture information is provided by each architecture
5868 package. The set of default architectures is selected by the macro
5869 `SELECT_ARCHITECTURES'. This is normally set up in the
5870 `config/TARGET.mt' file of your choice. If the name is not defined,
5871 then all the architectures supported are included.
5873 When BFD starts up, all the architectures are called with an
5874 initialize method. It is up to the architecture back end to insert as
5875 many items into the list of architectures as it wants to; generally
5876 this would be one for each machine and one for the default case (an
5877 item with a machine field of 0).
5879 BFD's idea of an architecture is implemented in `archures.c'.

5884 *Description*
5885 This enum gives the object file's CPU architecture, in a global
5886 sense--i.e., what processor family does it belong to? Another field
5887 indicates which processor within the family is in use. The machine
5888 gives a number which distinguishes different versions of the
5889 architecture, containing, for example, 2 and 3 for Intel i960 KA and
5890 i960 KB, and 68020 and 68030 for Motorola 68020 and 68030.

6428 2.14 Opening and closing BFDs
6429 =============================
6431 2.14.1 Functions for opening and closing
6432 ----------------------------------------
6434 2.14.1.1 `bfd_fopen'
6435 ....................
6437 *Synopsis*
6438 bfd *bfd_fopen (const char *filename, const char *target,
6439 const char *mode, int fd);
6440 *Description*
6441 Open the file FILENAME with the target TARGET. Return a pointer to the
6442 created BFD. If FD is not -1, then `fdopen' is used to open the file;
6443 otherwise, `fopen' is used. MODE is passed directly to `fopen' or
6444 `fdopen'.
6446 Calls `bfd_find_target', so TARGET is interpreted as by that
6447 function.
6449 The new BFD is marked as cacheable iff FD is -1.
6451 If `NULL' is returned then an error has occured. Possible errors
6452 are `bfd_error_no_memory', `bfd_error_invalid_target' or `system_call'
6453 error.
6455 2.14.1.2 `bfd_openr'
6456 ....................
6458 *Synopsis*
6459 bfd *bfd_openr (const char *filename, const char *target);
6460 *Description*
6461 Open the file FILENAME (using `fopen') with the target TARGET. Return
6462 a pointer to the created BFD.
6464 Calls `bfd_find_target', so TARGET is interpreted as by that
6465 function.
6467 If `NULL' is returned then an error has occured. Possible errors
6468 are `bfd_error_no_memory', `bfd_error_invalid_target' or `system_call'
6469 error.
6471 2.14.1.3 `bfd_fdopenr'
6472 ......................
6474 *Synopsis*
6475 bfd *bfd_fdopenr (const char *filename, const char *target, int fd);
6476 *Description*
6477 `bfd_fdopenr' is to `bfd_fopenr' much like `fdopen' is to `fopen'. It
6478 opens a BFD on a file already described by the FD supplied.
6480 When the file is later `bfd_close'd, the file descriptor will be
6481 closed. If the caller desires that this file descriptor be cached by
6482 BFD (opened as needed, closed as needed to free descriptors for other
6483 opens), with the supplied FD used as an initial file descriptor (but
6484 subject to closure at any time), call bfd_set_cacheable(bfd, 1) on the
6485 returned BFD. The default is to assume no caching; the file descriptor
6486 will remain open until `bfd_close', and will not be affected by BFD
6487 operations on other files.
6489 Possible errors are `bfd_error_no_memory',
6490 `bfd_error_invalid_target' and `bfd_error_system_call'.
6492 2.14.1.4 `bfd_openstreamr'
6493 ..........................
6495 *Synopsis*
6496 bfd *bfd_openstreamr (const char *, const char *, void *);
6497 *Description*
6498 Open a BFD for read access on an existing stdio stream. When the BFD
6499 is passed to `bfd_close', the stream will be closed.
6501 2.14.1.5 `bfd_openr_iovec'
6502 ..........................
6504 *Synopsis*
6505 bfd *bfd_openr_iovec (const char *filename, const char *target,
6506 void *(*open) (struct bfd *nbfd,
6507 void *open_closure),
6508 void *open_closure,
6509 file_ptr (*pread) (struct bfd *nbfd,
6510 void *stream,
6511 void *buf,
6512 file_ptr nbytes,
6513 file_ptr offset),
6514 int (*close) (struct bfd *nbfd,
6515 void *stream),
6516 int (*stat) (struct bfd *abfd,
6517 void *stream,
6518 struct stat *sb));
6519 *Description*
6520 Create and return a BFD backed by a read-only STREAM. The STREAM is
6521 created using OPEN, accessed using PREAD and destroyed using CLOSE.
6523 Calls `bfd_find_target', so TARGET is interpreted as by that
6524 function.
6526 Calls OPEN (which can call `bfd_zalloc' and `bfd_get_filename') to
6527 obtain the read-only stream backing the BFD. OPEN either succeeds
6528 returning the non-`NULL' STREAM, or fails returning `NULL' (setting
6529 `bfd_error').
6531 Calls PREAD to request NBYTES of data from STREAM starting at OFFSET
6532 (e.g., via a call to `bfd_read'). PREAD either succeeds returning the
6533 number of bytes read (which can be less than NBYTES when end-of-file),
6534 or fails returning -1 (setting `bfd_error').
6536 Calls CLOSE when the BFD is later closed using `bfd_close'. CLOSE
6537 either succeeds returning 0, or fails returning -1 (setting
6538 `bfd_error').
6540 Calls STAT to fill in a stat structure for bfd_stat, bfd_get_size,
6541 and bfd_get_mtime calls. STAT returns 0 on success, or returns -1 on
6542 failure (setting `bfd_error').
6544 If `bfd_openr_iovec' returns `NULL' then an error has occurred.
6545 Possible errors are `bfd_error_no_memory', `bfd_error_invalid_target'
6546 and `bfd_error_system_call'.
6548 2.14.1.6 `bfd_openw'
6549 ....................
6551 *Synopsis*
6552 bfd *bfd_openw (const char *filename, const char *target);
6553 *Description*
6554 Create a BFD, associated with file FILENAME, using the file format
6555 TARGET, and return a pointer to it.
6557 Possible errors are `bfd_error_system_call', `bfd_error_no_memory',
6558 `bfd_error_invalid_target'.
6560 2.14.1.7 `bfd_close'
6561 ....................
6563 *Synopsis*
6564 bfd_boolean bfd_close (bfd *abfd);
6565 *Description*
6566 Close a BFD. If the BFD was open for writing, then pending operations
6567 are completed and the file written out and closed. If the created file
6568 is executable, then `chmod' is called to mark it as such.
6570 All memory attached to the BFD is released.
6572 The file descriptor associated with the BFD is closed (even if it
6573 was passed in to BFD by `bfd_fdopenr').
6575 *Returns*
6576 `TRUE' is returned if all is ok, otherwise `FALSE'.
6578 2.14.1.8 `bfd_close_all_done'
6579 .............................
6581 *Synopsis*
6582 bfd_boolean bfd_close_all_done (bfd *);
6583 *Description*
6584 Close a BFD. Differs from `bfd_close' since it does not complete any
6585 pending operations. This routine would be used if the application had
6586 just used BFD for swapping and didn't want to use any of the writing
6587 code.
6589 If the created file is executable, then `chmod' is called to mark it
6590 as such.
6592 All memory attached to the BFD is released.
6594 *Returns*
6595 `TRUE' is returned if all is ok, otherwise `FALSE'.

6600 *Synopsis*
6601 bfd *bfd_create (const char *filename, bfd *templ);
6602 *Description*
6603 Create a new BFD in the manner of `bfd_openw', but without opening a
6604 file. The new BFD takes the target from the target used by TEMPLATE.
6605 The format is always set to `bfd_object'.

6608 .............................
6610 *Synopsis*
6611 bfd_boolean bfd_make_writable (bfd *abfd);
6612 *Description*
6613 Takes a BFD as created by `bfd_create' and converts it into one like as
6614 returned by `bfd_openw'. It does this by converting the BFD to
6615 BFD_IN_MEMORY. It's assumed that you will call `bfd_make_readable' on
6616 this bfd later.
6618 *Returns*
6619 `TRUE' is returned if all is ok, otherwise `FALSE'.

6626 *Description*
6627 Takes a BFD as created by `bfd_create' and `bfd_make_writable' and
6628 converts it into one like as returned by `bfd_openr'. It does this by
6629 writing the contents out to the memory buffer, then reversing the
6630 direction.
6632 *Returns*
6633 `TRUE' is returned if all is ok, otherwise `FALSE'.

6707 *Synopsis*
6708 char *find_separate_debug_file (bfd *abfd);
6709 *Description*
6710 Searches ABFD for a reference to separate debugging information, scans
6711 various locations in the filesystem, including the file tree rooted at
6712 DEBUG_FILE_DIRECTORY, and returns a filename of such debugging
6713 information if the file is found and has matching CRC32. Returns NULL
6714 if no reference to debugging file exists, or file cannot be found.
6716 2.14.1.20 `bfd_follow_gnu_debuglink'
6717 ....................................
6719 *Synopsis*
6720 char *bfd_follow_gnu_debuglink (bfd *abfd, const char *dir);
6721 *Description*
6722 Takes a BFD and searches it for a .gnu_debuglink section. If this
6723 section is found, it examines the section for the name and checksum of
6724 a '.debug' file containing auxiliary debugging information. It then
6725 searches the filesystem for this .debug file in some standard
6726 locations, including the directory tree rooted at DIR, and if found
6727 returns the full filename.
6729 If DIR is NULL, it will search a default path configured into libbfd
6730 at build time. [XXX this feature is not currently implemented].
6732 *Returns*
6733 `NULL' on any errors or failure to locate the .debug file, otherwise a
6734 pointer to a heap-allocated string containing the filename. The caller
6735 is responsible for freeing this string.

6772 2.15.1 Internal functions
6773 -------------------------
6775 *Description*
6776 These routines are used within BFD. They are not intended for export,
6777 but are documented here for completeness.
6779 2.15.1.1 `bfd_write_bigendian_4byte_int'
6780 ........................................
6782 *Synopsis*
6783 bfd_boolean bfd_write_bigendian_4byte_int (bfd *, unsigned int);
6784 *Description*
6785 Write a 4 byte integer I to the output BFD ABFD, in big endian order
6786 regardless of what else is going on. This is useful in archives.
6788 2.15.1.2 `bfd_put_size'
6789 .......................
6791 2.15.1.3 `bfd_get_size'
6792 .......................
6794 *Description*
6795 These macros as used for reading and writing raw data in sections; each
6796 access (except for bytes) is vectored through the target format of the
6797 BFD and mangled accordingly. The mangling performs any necessary endian
6798 translations and removes alignment restrictions. Note that types
6799 accepted and returned by these macros are identical so they can be
6800 swapped around in macros--for example, `libaout.h' defines `GET_WORD'
6801 to either `bfd_get_32' or `bfd_get_64'.
6803 In the put routines, VAL must be a `bfd_vma'. If we are on a system
6804 without prototypes, the caller is responsible for making sure that is
6805 true, with a cast if necessary. We don't cast them in the macro
6806 definitions because that would prevent `lint' or `gcc -Wall' from
6807 detecting sins such as passing a pointer. To detect calling these with
6808 less than a `bfd_vma', use `gcc -Wconversion' on a host with 64 bit
6809 `bfd_vma''s.

6942 2.16 File caching
6943 =================
6945 The file caching mechanism is embedded within BFD and allows the
6946 application to open as many BFDs as it wants without regard to the
6947 underlying operating system's file descriptor limit (often as low as 20
6948 open files). The module in `cache.c' maintains a least recently used
6949 list of `BFD_CACHE_MAX_OPEN' files, and exports the name
6950 `bfd_cache_lookup', which runs around and makes sure that the required
6951 BFD is open. If not, then it chooses a file to close, closes it and
6952 opens the one wanted, returning its file handle.

7006 2.17 Linker Functions
7007 =====================
7009 The linker uses three special entry points in the BFD target vector.
7010 It is not necessary to write special routines for these entry points
7011 when creating a new BFD back end, since generic versions are provided.
7012 However, writing them can speed up linking and make it use
7013 significantly less runtime memory.
7015 The first routine creates a hash table used by the other routines.
7016 The second routine adds the symbols from an object file to the hash
7017 table. The third routine takes all the object files and links them
7018 together to create the output file. These routines are designed so
7019 that the linker proper does not need to know anything about the symbols
7020 in the object files that it is linking. The linker merely arranges the
7021 sections as directed by the linker script and lets BFD handle the
7022 details of symbols and relocs.
7024 The second routine and third routines are passed a pointer to a
7025 `struct bfd_link_info' structure (defined in `bfdlink.h') which holds
7026 information relevant to the link, including the linker hash table
7027 (which was created by the first routine) and a set of callback
7028 functions to the linker proper.
7030 The generic linker routines are in `linker.c', and use the header
7031 file `genlink.h'. As of this writing, the only back ends which have
7032 implemented versions of these routines are a.out (in `aoutx.h') and
7033 ECOFF (in `ecoff.c'). The a.out routines are used as examples
7034 throughout this section.

7045 2.17.1 Creating a linker hash table
7046 -----------------------------------
7048 The linker routines must create a hash table, which must be derived
7049 from `struct bfd_link_hash_table' described in `bfdlink.c'. *Note Hash
7050 Tables::, for information on how to create a derived hash table. This
7051 entry point is called using the target vector of the linker output file.
7053 The `_bfd_link_hash_table_create' entry point must allocate and
7054 initialize an instance of the desired hash table. If the back end does
7055 not require any additional information to be stored with the entries in
7056 the hash table, the entry point may simply create a `struct
7057 bfd_link_hash_table'. Most likely, however, some additional
7058 information will be needed.
7060 For example, with each entry in the hash table the a.out linker
7061 keeps the index the symbol has in the final output file (this index
7062 number is used so that when doing a relocatable link the symbol index
7063 used in the output file can be quickly filled in when copying over a
7064 reloc). The a.out linker code defines the required structures and
7065 functions for a hash table derived from `struct bfd_link_hash_table'.
7066 The a.out linker hash table is created by the function
7067 `NAME(aout,link_hash_table_create)'; it simply allocates space for the
7068 hash table, initializes it, and returns a pointer to it.
7070 When writing the linker routines for a new back end, you will
7071 generally not know exactly which fields will be required until you have
7072 finished. You should simply create a new hash table which defines no
7073 additional fields, and then simply add fields as they become necessary.

7078 2.17.2 Adding symbols to the hash table
7079 ---------------------------------------
7081 The linker proper will call the `_bfd_link_add_symbols' entry point for
7082 each object file or archive which is to be linked (typically these are
7083 the files named on the command line, but some may also come from the
7084 linker script). The entry point is responsible for examining the file.
7085 For an object file, BFD must add any relevant symbol information to
7086 the hash table. For an archive, BFD must determine which elements of
7087 the archive should be used and adding them to the link.
7089 The a.out version of this entry point is
7090 `NAME(aout,link_add_symbols)'.

7101 2.17.2.1 Differing file formats
7102 ...............................
7104 Normally all the files involved in a link will be of the same format,
7105 but it is also possible to link together different format object files,
7106 and the back end must support that. The `_bfd_link_add_symbols' entry
7107 point is called via the target vector of the file to be added. This
7108 has an important consequence: the function may not assume that the hash
7109 table is the type created by the corresponding
7110 `_bfd_link_hash_table_create' vector. All the `_bfd_link_add_symbols'
7111 function can assume about the hash table is that it is derived from
7112 `struct bfd_link_hash_table'.
7114 Sometimes the `_bfd_link_add_symbols' function must store some
7115 information in the hash table entry to be used by the `_bfd_final_link'
7116 function. In such a case the `creator' field of the hash table must be
7117 checked to make sure that the hash table was created by an object file
7118 of the same format.
7120 The `_bfd_final_link' routine must be prepared to handle a hash
7121 entry without any extra information added by the
7122 `_bfd_link_add_symbols' function. A hash entry without extra
7123 information will also occur when the linker script directs the linker
7124 to create a symbol. Note that, regardless of how a hash table entry is
7125 added, all the fields will be initialized to some sort of null value by
7126 the hash table entry initialization function.
7128 See `ecoff_link_add_externals' for an example of how to check the
7129 `creator' field before saving information (in this case, the ECOFF
7130 external symbol debugging information) in a hash table entry.

7135 2.17.2.2 Adding symbols from an object file
7136 ...........................................
7138 When the `_bfd_link_add_symbols' routine is passed an object file, it
7139 must add all externally visible symbols in that object file to the hash
7140 table. The actual work of adding the symbol to the hash table is
7141 normally handled by the function `_bfd_generic_link_add_one_symbol'.
7142 The `_bfd_link_add_symbols' routine is responsible for reading all the
7143 symbols from the object file and passing the correct information to
7144 `_bfd_generic_link_add_one_symbol'.
7146 The `_bfd_link_add_symbols' routine should not use
7147 `bfd_canonicalize_symtab' to read the symbols. The point of providing
7148 this routine is to avoid the overhead of converting the symbols into
7149 generic `asymbol' structures.
7151 `_bfd_generic_link_add_one_symbol' handles the details of combining
7152 common symbols, warning about multiple definitions, and so forth. It
7153 takes arguments which describe the symbol to add, notably symbol flags,
7154 a section, and an offset. The symbol flags include such things as
7155 `BSF_WEAK' or `BSF_INDIRECT'. The section is a section in the object
7156 file, or something like `bfd_und_section_ptr' for an undefined symbol
7157 or `bfd_com_section_ptr' for a common symbol.
7159 If the `_bfd_final_link' routine is also going to need to read the
7160 symbol information, the `_bfd_link_add_symbols' routine should save it
7161 somewhere attached to the object file BFD. However, the information
7162 should only be saved if the `keep_memory' field of the `info' argument
7163 is TRUE, so that the `-no-keep-memory' linker switch is effective.
7165 The a.out function which adds symbols from an object file is
7166 `aout_link_add_object_symbols', and most of the interesting work is in
7167 `aout_link_add_symbols'. The latter saves pointers to the hash tables
7168 entries created by `_bfd_generic_link_add_one_symbol' indexed by symbol
7169 number, so that the `_bfd_final_link' routine does not have to call the
7170 hash table lookup routine to locate the entry.

7175 2.17.2.3 Adding symbols from an archive
7176 .......................................
7178 When the `_bfd_link_add_symbols' routine is passed an archive, it must
7179 look through the symbols defined by the archive and decide which
7180 elements of the archive should be included in the link. For each such
7181 element it must call the `add_archive_element' linker callback, and it
7182 must add the symbols from the object file to the linker hash table.
7184 In most cases the work of looking through the symbols in the archive
7185 should be done by the `_bfd_generic_link_add_archive_symbols' function.
7186 This function builds a hash table from the archive symbol table and
7187 looks through the list of undefined symbols to see which elements
7188 should be included. `_bfd_generic_link_add_archive_symbols' is passed
7189 a function to call to make the final decision about adding an archive
7190 element to the link and to do the actual work of adding the symbols to
7191 the linker hash table.
7193 The function passed to `_bfd_generic_link_add_archive_symbols' must
7194 read the symbols of the archive element and decide whether the archive
7195 element should be included in the link. If the element is to be
7196 included, the `add_archive_element' linker callback routine must be
7197 called with the element as an argument, and the elements symbols must
7198 be added to the linker hash table just as though the element had itself
7199 been passed to the `_bfd_link_add_symbols' function.
7201 When the a.out `_bfd_link_add_symbols' function receives an archive,
7202 it calls `_bfd_generic_link_add_archive_symbols' passing
7203 `aout_link_check_archive_element' as the function argument.
7204 `aout_link_check_archive_element' calls `aout_link_check_ar_symbols'.
7205 If the latter decides to add the element (an element is only added if
7206 it provides a real, non-common, definition for a previously undefined
7207 or common symbol) it calls the `add_archive_element' callback and then
7208 `aout_link_check_archive_element' calls `aout_link_add_symbols' to
7209 actually add the symbols to the linker hash table.
7211 The ECOFF back end is unusual in that it does not normally call
7212 `_bfd_generic_link_add_archive_symbols', because ECOFF archives already
7213 contain a hash table of symbols. The ECOFF back end searches the
7214 archive itself to avoid the overhead of creating a new hash table.

7219 2.17.3 Performing the final link
7220 --------------------------------
7222 When all the input files have been processed, the linker calls the
7223 `_bfd_final_link' entry point of the output BFD. This routine is
7224 responsible for producing the final output file, which has several
7225 aspects. It must relocate the contents of the input sections and copy
7226 the data into the output sections. It must build an output symbol
7227 table including any local symbols from the input files and the global
7228 symbols from the hash table. When producing relocatable output, it must
7229 modify the input relocs and write them into the output file. There may
7230 also be object format dependent work to be done.
7232 The linker will also call the `write_object_contents' entry point
7233 when the BFD is closed. The two entry points must work together in
7234 order to produce the correct output file.
7236 The details of how this works are inevitably dependent upon the
7237 specific object file format. The a.out `_bfd_final_link' routine is
7238 `NAME(aout,final_link)'.

7249 2.17.3.1 Information provided by the linker
7250 ...........................................
7252 Before the linker calls the `_bfd_final_link' entry point, it sets up
7253 some data structures for the function to use.
7255 The `input_bfds' field of the `bfd_link_info' structure will point
7256 to a list of all the input files included in the link. These files are
7257 linked through the `link_next' field of the `bfd' structure.
7259 Each section in the output file will have a list of `link_order'
7260 structures attached to the `map_head.link_order' field (the
7261 `link_order' structure is defined in `bfdlink.h'). These structures
7262 describe how to create the contents of the output section in terms of
7263 the contents of various input sections, fill constants, and,
7264 eventually, other types of information. They also describe relocs that
7265 must be created by the BFD backend, but do not correspond to any input
7266 file; this is used to support -Ur, which builds constructors while
7267 generating a relocatable object file.

7272 2.17.3.2 Relocating the section contents
7273 ........................................
7275 The `_bfd_final_link' function should look through the `link_order'
7276 structures attached to each section of the output file. Each
7277 `link_order' structure should either be handled specially, or it should
7278 be passed to the function `_bfd_default_link_order' which will do the
7279 right thing (`_bfd_default_link_order' is defined in `linker.c').
7281 For efficiency, a `link_order' of type `bfd_indirect_link_order'
7282 whose associated section belongs to a BFD of the same format as the
7283 output BFD must be handled specially. This type of `link_order'
7284 describes part of an output section in terms of a section belonging to
7285 one of the input files. The `_bfd_final_link' function should read the
7286 contents of the section and any associated relocs, apply the relocs to
7287 the section contents, and write out the modified section contents. If
7288 performing a relocatable link, the relocs themselves must also be
7289 modified and written out.
7291 The functions `_bfd_relocate_contents' and
7292 `_bfd_final_link_relocate' provide some general support for performing
7293 the actual relocations, notably overflow checking. Their arguments
7294 include information about the symbol the relocation is against and a
7295 `reloc_howto_type' argument which describes the relocation to perform.
7296 These functions are defined in `reloc.c'.
7298 The a.out function which handles reading, relocating, and writing
7299 section contents is `aout_link_input_section'. The actual relocation
7300 is done in `aout_link_input_section_std' and
7301 `aout_link_input_section_ext'.

7306 2.17.3.3 Writing the symbol table
7307 .................................
7309 The `_bfd_final_link' function must gather all the symbols in the input
7310 files and write them out. It must also write out all the symbols in
7311 the global hash table. This must be controlled by the `strip' and
7312 `discard' fields of the `bfd_link_info' structure.
7314 The local symbols of the input files will not have been entered into
7315 the linker hash table. The `_bfd_final_link' routine must consider
7316 each input file and include the symbols in the output file. It may be
7317 convenient to do this when looking through the `link_order' structures,
7318 or it may be done by stepping through the `input_bfds' list.
7320 The `_bfd_final_link' routine must also traverse the global hash
7321 table to gather all the externally visible symbols. It is possible
7322 that most of the externally visible symbols may be written out when
7323 considering the symbols of each input file, but it is still necessary
7324 to traverse the hash table since the linker script may have defined
7325 some symbols that are not in any of the input files.
7327 The `strip' field of the `bfd_link_info' structure controls which
7328 symbols are written out. The possible values are listed in
7329 `bfdlink.h'. If the value is `strip_some', then the `keep_hash' field
7330 of the `bfd_link_info' structure is a hash table of symbols to keep;
7331 each symbol should be looked up in this hash table, and only symbols
7332 which are present should be included in the output file.
7334 If the `strip' field of the `bfd_link_info' structure permits local
7335 symbols to be written out, the `discard' field is used to further
7336 controls which local symbols are included in the output file. If the
7337 value is `discard_l', then all local symbols which begin with a certain
7338 prefix are discarded; this is controlled by the
7339 `bfd_is_local_label_name' entry point.
7341 The a.out backend handles symbols by calling
7342 `aout_link_write_symbols' on each input BFD and then traversing the
7343 global hash table with the function `aout_link_write_other_symbol'. It
7344 builds a string table while writing out the symbols, which is written
7345 to the output file at the end of `NAME(aout,final_link)'.

7373 2.18 Hash Tables
7374 ================
7376 BFD provides a simple set of hash table functions. Routines are
7377 provided to initialize a hash table, to free a hash table, to look up a
7378 string in a hash table and optionally create an entry for it, and to
7379 traverse a hash table. There is currently no routine to delete an
7380 string from a hash table.
7382 The basic hash table does not permit any data to be stored with a
7383 string. However, a hash table is designed to present a base class from
7384 which other types of hash tables may be derived. These derived types
7385 may store additional information with the string. Hash tables were
7386 implemented in this way, rather than simply providing a data pointer in
7387 a hash table entry, because they were designed for use by the linker
7388 back ends. The linker may create thousands of hash table entries, and
7389 the overhead of allocating private data and storing and following
7390 pointers becomes noticeable.
7392 The basic hash table code is in `hash.c'.

7404 2.18.1 Creating and freeing a hash table
7405 ----------------------------------------
7407 To create a hash table, create an instance of a `struct bfd_hash_table'
7408 (defined in `bfd.h') and call `bfd_hash_table_init' (if you know
7409 approximately how many entries you will need, the function
7410 `bfd_hash_table_init_n', which takes a SIZE argument, may be used).
7411 `bfd_hash_table_init' returns `FALSE' if some sort of error occurs.
7413 The function `bfd_hash_table_init' take as an argument a function to
7414 use to create new entries. For a basic hash table, use the function
7415 `bfd_hash_newfunc'. *Note Deriving a New Hash Table Type::, for why
7416 you would want to use a different value for this argument.
7418 `bfd_hash_table_init' will create an objalloc which will be used to
7419 allocate new entries. You may allocate memory on this objalloc using
7420 `bfd_hash_allocate'.
7422 Use `bfd_hash_table_free' to free up all the memory that has been
7423 allocated for a hash table. This will not free up the `struct
7424 bfd_hash_table' itself, which you must provide.
7426 Use `bfd_hash_set_default_size' to set the default size of hash
7427 table to use.

7432 2.18.2 Looking up or entering a string
7433 --------------------------------------
7435 The function `bfd_hash_lookup' is used both to look up a string in the
7436 hash table and to create a new entry.
7438 If the CREATE argument is `FALSE', `bfd_hash_lookup' will look up a
7439 string. If the string is found, it will returns a pointer to a `struct
7440 bfd_hash_entry'. If the string is not found in the table
7441 `bfd_hash_lookup' will return `NULL'. You should not modify any of the
7442 fields in the returns `struct bfd_hash_entry'.
7444 If the CREATE argument is `TRUE', the string will be entered into
7445 the hash table if it is not already there. Either way a pointer to a
7446 `struct bfd_hash_entry' will be returned, either to the existing
7447 structure or to a newly created one. In this case, a `NULL' return
7448 means that an error occurred.
7450 If the CREATE argument is `TRUE', and a new entry is created, the
7451 COPY argument is used to decide whether to copy the string onto the
7452 hash table objalloc or not. If COPY is passed as `FALSE', you must be
7453 careful not to deallocate or modify the string as long as the hash table
7454 exists.

7459 2.18.3 Traversing a hash table
7460 ------------------------------
7462 The function `bfd_hash_traverse' may be used to traverse a hash table,
7463 calling a function on each element. The traversal is done in a random
7464 order.
7466 `bfd_hash_traverse' takes as arguments a function and a generic
7467 `void *' pointer. The function is called with a hash table entry (a
7468 `struct bfd_hash_entry *') and the generic pointer passed to
7469 `bfd_hash_traverse'. The function must return a `boolean' value, which
7470 indicates whether to continue traversing the hash table. If the
7471 function returns `FALSE', `bfd_hash_traverse' will stop the traversal
7472 and return immediately.

7477 2.18.4 Deriving a new hash table type
7478 -------------------------------------
7480 Many uses of hash tables want to store additional information which
7481 each entry in the hash table. Some also find it convenient to store
7482 additional information with the hash table itself. This may be done
7483 using a derived hash table.
7485 Since C is not an object oriented language, creating a derived hash
7486 table requires sticking together some boilerplate routines with a few
7487 differences specific to the type of hash table you want to create.
7489 An example of a derived hash table is the linker hash table. The
7490 structures for this are defined in `bfdlink.h'. The functions are in
7491 `linker.c'.
7493 You may also derive a hash table from an already derived hash table.
7494 For example, the a.out linker backend code uses a hash table derived
7495 from the linker hash table.

7506 2.18.4.1 Define the derived structures
7507 ......................................
7509 You must define a structure for an entry in the hash table, and a
7510 structure for the hash table itself.
7512 The first field in the structure for an entry in the hash table must
7513 be of the type used for an entry in the hash table you are deriving
7514 from. If you are deriving from a basic hash table this is `struct
7515 bfd_hash_entry', which is defined in `bfd.h'. The first field in the
7516 structure for the hash table itself must be of the type of the hash
7517 table you are deriving from itself. If you are deriving from a basic
7518 hash table, this is `struct bfd_hash_table'.
7520 For example, the linker hash table defines `struct
7521 bfd_link_hash_entry' (in `bfdlink.h'). The first field, `root', is of
7522 type `struct bfd_hash_entry'. Similarly, the first field in `struct
7523 bfd_link_hash_table', `table', is of type `struct bfd_hash_table'.

7528 2.18.4.2 Write the derived creation routine
7529 ...........................................
7531 You must write a routine which will create and initialize an entry in
7532 the hash table. This routine is passed as the function argument to
7533 `bfd_hash_table_init'.
7535 In order to permit other hash tables to be derived from the hash
7536 table you are creating, this routine must be written in a standard way.
7538 The first argument to the creation routine is a pointer to a hash
7539 table entry. This may be `NULL', in which case the routine should
7540 allocate the right amount of space. Otherwise the space has already
7541 been allocated by a hash table type derived from this one.
7543 After allocating space, the creation routine must call the creation
7544 routine of the hash table type it is derived from, passing in a pointer
7545 to the space it just allocated. This will initialize any fields used
7546 by the base hash table.
7548 Finally the creation routine must initialize any local fields for
7549 the new hash table type.
7551 Here is a boilerplate example of a creation routine. FUNCTION_NAME
7552 is the name of the routine. ENTRY_TYPE is the type of an entry in the
7553 hash table you are creating. BASE_NEWFUNC is the name of the creation
7554 routine of the hash table type your hash table is derived from.

7578 return (struct bfd_hash_entry *) ret;

7580 *Description*
7581 The creation routine for the linker hash table, which is in `linker.c',
7582 looks just like this example. FUNCTION_NAME is
7583 `_bfd_link_hash_newfunc'. ENTRY_TYPE is `struct bfd_link_hash_entry'.
7584 BASE_NEWFUNC is `bfd_hash_newfunc', the creation routine for a basic
7585 hash table.
7587 `_bfd_link_hash_newfunc' also initializes the local fields in a
7588 linker hash table entry: `type', `written' and `next'.

7593 2.18.4.3 Write other derived routines
7594 .....................................
7596 You will want to write other routines for your new hash table, as well.
7598 You will want an initialization routine which calls the
7599 initialization routine of the hash table you are deriving from and
7600 initializes any other local fields. For the linker hash table, this is
7601 `_bfd_link_hash_table_init' in `linker.c'.
7603 You will want a lookup routine which calls the lookup routine of the
7604 hash table you are deriving from and casts the result. The linker hash
7605 table uses `bfd_link_hash_lookup' in `linker.c' (this actually takes an
7606 additional argument which it uses to decide how to return the looked up
7607 value).
7609 You may want a traversal routine. This should just call the
7610 traversal routine of the hash table you are deriving from with
7611 appropriate casts. The linker hash table uses `bfd_link_hash_traverse'
7612 in `linker.c'.
7614 These routines may simply be defined as macros. For example, the
7615 a.out backend linker hash table, which is derived from the linker hash
7616 table, uses macros for the lookup and traversal routines. These are
7617 `aout_link_hash_lookup' and `aout_link_hash_traverse' in aoutx.h.

7644 3.2 a.out backends
7645 ==================
7647 *Description*
7648 BFD supports a number of different flavours of a.out format, though the
7649 major differences are only the sizes of the structures on disk, and the
7650 shape of the relocation information.
7652 The support is split into a basic support file `aoutx.h' and other
7653 files which derive functions from the base. One derivation file is
7654 `aoutf1.h' (for a.out flavour 1), and adds to the basic a.out functions
7655 support for sun3, sun4, 386 and 29k a.out files, to create a target
7656 jump vector for a specific target.
7658 This information is further split out into more specific files for
7659 each machine, including `sunos.c' for sun3 and sun4, `newsos3.c' for
7660 the Sony NEWS, and `demo64.c' for a demonstration of a 64 bit a.out
7661 format.
7663 The base file `aoutx.h' defines general mechanisms for reading and
7664 writing records to and from disk and various other methods which BFD
7665 requires. It is included by `aout32.c' and `aout64.c' to form the names
7666 `aout_32_swap_exec_header_in', `aout_64_swap_exec_header_in', etc.
7668 As an example, this is what goes on to make the back end for a sun4,
7669 from `aout32.c':
7671 #define ARCH_SIZE 32
7672 #include "aoutx.h"
7674 Which exports names:
7676 ...
7677 aout_32_canonicalize_reloc
7678 aout_32_find_nearest_line
7679 aout_32_get_lineno
7680 aout_32_get_reloc_upper_bound
7681 ...
7683 from `sunos.c':
7685 #define TARGET_NAME "a.out-sunos-big"
7686 #define VECNAME sunos_big_vec
7687 #include "aoutf1.h"
7689 requires all the names from `aout32.c', and produces the jump vector
7691 sunos_big_vec
7693 The file `host-aout.c' is a special case. It is for a large set of
7694 hosts that use "more or less standard" a.out files, and for which
7695 cross-debugging is not interesting. It uses the standard 32-bit a.out
7696 support routines, but determines the file offsets and addresses of the
7697 text, data, and BSS sections, the machine architecture and machine
7698 type, and the entry point address, in a host-dependent manner. Once
7699 these values have been determined, generic code is used to handle the
7700 object file.
7702 When porting it to run on a new system, you must supply:
7704 HOST_PAGE_SIZE
7705 HOST_SEGMENT_SIZE
7706 HOST_MACHINE_ARCH (optional)
7707 HOST_MACHINE_MACHINE (optional)
7708 HOST_TEXT_START_ADDR
7709 HOST_STACK_END_ADDR
7711 in the file `../include/sys/h-XXX.h' (for your host). These values,
7712 plus the structures and macros defined in `a.out.h' on your host
7713 system, will produce a BFD target that will access ordinary a.out files
7714 on your host. To configure a new machine to use `host-aout.c', specify:
7716 TDEFAULTS = -DDEFAULT_VECTOR=host_aout_big_vec
7717 TDEPFILES= host-aout.o trad-core.o
7719 in the `config/XXX.mt' file, and modify `configure.in' to use the
7720 `XXX.mt' file (by setting "`bfd_target=XXX'") when your configuration
7721 is selected.
7723 3.2.1 Relocations
7724 -----------------
7726 *Description*
7727 The file `aoutx.h' provides for both the _standard_ and _extended_
7728 forms of a.out relocation records.
7730 The standard records contain only an address, a symbol index, and a
7731 type field. The extended records (used on 29ks and sparcs) also have a
7732 full integer for an addend.
7734 3.2.2 Internal entry points
7735 ---------------------------
7737 *Description*
7738 `aoutx.h' exports several routines for accessing the contents of an
7739 a.out file, which are gathered and exported in turn by various format
7740 specific files (eg sunos.c).

7831 3.3 coff backends
7832 =================
7834 BFD supports a number of different flavours of coff format. The major
7835 differences between formats are the sizes and alignments of fields in
7836 structures on disk, and the occasional extra field.
7838 Coff in all its varieties is implemented with a few common files and
7839 a number of implementation specific files. For example, The 88k bcs
7840 coff format is implemented in the file `coff-m88k.c'. This file
7841 `#include's `coff/m88k.h' which defines the external structure of the
7842 coff format for the 88k, and `coff/internal.h' which defines the
7843 internal structure. `coff-m88k.c' also defines the relocations used by
7844 the 88k format *Note Relocations::.
7846 The Intel i960 processor version of coff is implemented in
7847 `coff-i960.c'. This file has the same structure as `coff-m88k.c',
7848 except that it includes `coff/i960.h' rather than `coff-m88k.h'.
7850 3.3.1 Porting to a new version of coff
7851 --------------------------------------
7853 The recommended method is to select from the existing implementations
7854 the version of coff which is most like the one you want to use. For
7855 example, we'll say that i386 coff is the one you select, and that your
7856 coff flavour is called foo. Copy `i386coff.c' to `foocoff.c', copy
7857 `../include/coff/i386.h' to `../include/coff/foo.h', and add the lines
7858 to `targets.c' and `Makefile.in' so that your new back end is used.
7859 Alter the shapes of the structures in `../include/coff/foo.h' so that
7860 they match what you need. You will probably also have to add `#ifdef's
7861 to the code in `coff/internal.h' and `coffcode.h' if your version of
7862 coff is too wild.
7864 You can verify that your new BFD backend works quite simply by
7865 building `objdump' from the `binutils' directory, and making sure that
7866 its version of what's going on and your host system's idea (assuming it
7867 has the pretty standard coff dump utility, usually called `att-dump' or
7868 just `dump') are the same. Then clean up your code, and send what
7869 you've done to Cygnus. Then your stuff will be in the next release, and
7870 you won't have to keep integrating it.
7872 3.3.2 How the coff backend works
7873 --------------------------------
7875 3.3.2.1 File layout
7876 ...................
7878 The Coff backend is split into generic routines that are applicable to
7879 any Coff target and routines that are specific to a particular target.
7880 The target-specific routines are further split into ones which are
7881 basically the same for all Coff targets except that they use the
7882 external symbol format or use different values for certain constants.
7884 The generic routines are in `coffgen.c'. These routines work for
7885 any Coff target. They use some hooks into the target specific code;
7886 the hooks are in a `bfd_coff_backend_data' structure, one of which
7887 exists for each target.
7889 The essentially similar target-specific routines are in
7890 `coffcode.h'. This header file includes executable C code. The
7891 various Coff targets first include the appropriate Coff header file,
7892 make any special defines that are needed, and then include `coffcode.h'.
7894 Some of the Coff targets then also have additional routines in the
7895 target source file itself.
7897 For example, `coff-i960.c' includes `coff/internal.h' and
7898 `coff/i960.h'. It then defines a few constants, such as `I960', and
7899 includes `coffcode.h'. Since the i960 has complex relocation types,
7900 `coff-i960.c' also includes some code to manipulate the i960 relocs.
7901 This code is not in `coffcode.h' because it would not be used by any
7902 other target.
7904 3.3.2.2 Bit twiddling
7905 .....................
7907 Each flavour of coff supported in BFD has its own header file
7908 describing the external layout of the structures. There is also an
7909 internal description of the coff layout, in `coff/internal.h'. A major
7910 function of the coff backend is swapping the bytes and twiddling the
7911 bits to translate the external form of the structures into the normal
7912 internal form. This is all performed in the `bfd_swap'_thing_direction
7913 routines. Some elements are different sizes between different versions
7914 of coff; it is the duty of the coff version specific include file to
7915 override the definitions of various packing routines in `coffcode.h'.
7916 E.g., the size of line number entry in coff is sometimes 16 bits, and
7917 sometimes 32 bits. `#define'ing `PUT_LNSZ_LNNO' and `GET_LNSZ_LNNO'
7918 will select the correct one. No doubt, some day someone will find a
7919 version of coff which has a varying field size not catered to at the
7920 moment. To port BFD, that person will have to add more `#defines'.
7921 Three of the bit twiddling routines are exported to `gdb';
7922 `coff_swap_aux_in', `coff_swap_sym_in' and `coff_swap_lineno_in'. `GDB'
7923 reads the symbol table on its own, but uses BFD to fix things up. More
7924 of the bit twiddlers are exported for `gas'; `coff_swap_aux_out',
7925 `coff_swap_sym_out', `coff_swap_lineno_out', `coff_swap_reloc_out',
7926 `coff_swap_filehdr_out', `coff_swap_aouthdr_out',
7927 `coff_swap_scnhdr_out'. `Gas' currently keeps track of all the symbol
7928 table and reloc drudgery itself, thereby saving the internal BFD
7929 overhead, but uses BFD to swap things on the way out, making cross
7930 ports much safer. Doing so also allows BFD (and thus the linker) to
7931 use the same header files as `gas', which makes one avenue to disaster
7932 disappear.
7934 3.3.2.3 Symbol reading
7935 ......................
7937 The simple canonical form for symbols used by BFD is not rich enough to
7938 keep all the information available in a coff symbol table. The back end
7939 gets around this problem by keeping the original symbol table around,
7940 "behind the scenes".
7942 When a symbol table is requested (through a call to
7943 `bfd_canonicalize_symtab'), a request gets through to
7944 `coff_get_normalized_symtab'. This reads the symbol table from the coff
7945 file and swaps all the structures inside into the internal form. It
7946 also fixes up all the pointers in the table (represented in the file by
7947 offsets from the first symbol in the table) into physical pointers to
7948 elements in the new internal table. This involves some work since the
7949 meanings of fields change depending upon context: a field that is a
7950 pointer to another structure in the symbol table at one moment may be
7951 the size in bytes of a structure at the next. Another pass is made
7952 over the table. All symbols which mark file names (`C_FILE' symbols)
7953 are modified so that the internal string points to the value in the
7954 auxent (the real filename) rather than the normal text associated with
7955 the symbol (`".file"').
7957 At this time the symbol names are moved around. Coff stores all
7958 symbols less than nine characters long physically within the symbol
7959 table; longer strings are kept at the end of the file in the string
7960 table. This pass moves all strings into memory and replaces them with
7961 pointers to the strings.
7963 The symbol table is massaged once again, this time to create the
7964 canonical table used by the BFD application. Each symbol is inspected
7965 in turn, and a decision made (using the `sclass' field) about the
7966 various flags to set in the `asymbol'. *Note Symbols::. The generated
7967 canonical table shares strings with the hidden internal symbol table.
7969 Any linenumbers are read from the coff file too, and attached to the
7970 symbols which own the functions the linenumbers belong to.
7972 3.3.2.4 Symbol writing
7973 ......................
7975 Writing a symbol to a coff file which didn't come from a coff file will
7976 lose any debugging information. The `asymbol' structure remembers the
7977 BFD from which the symbol was taken, and on output the back end makes
7978 sure that the same destination target as source target is present.
7980 When the symbols have come from a coff file then all the debugging
7981 information is preserved.
7983 Symbol tables are provided for writing to the back end in a vector
7984 of pointers to pointers. This allows applications like the linker to
7985 accumulate and output large symbol tables without having to do too much
7986 byte copying.
7988 This function runs through the provided symbol table and patches
7989 each symbol marked as a file place holder (`C_FILE') to point to the
7990 next file place holder in the list. It also marks each `offset' field
7991 in the list with the offset from the first symbol of the current symbol.
7993 Another function of this procedure is to turn the canonical value
7994 form of BFD into the form used by coff. Internally, BFD expects symbol
7995 values to be offsets from a section base; so a symbol physically at
7996 0x120, but in a section starting at 0x100, would have the value 0x20.
7997 Coff expects symbols to contain their final value, so symbols have
7998 their values changed at this point to reflect their sum with their
7999 owning section. This transformation uses the `output_section' field of
8000 the `asymbol''s `asection' *Note Sections::.
8002 * `coff_mangle_symbols'
8003 This routine runs though the provided symbol table and uses the
8004 offsets generated by the previous pass and the pointers generated when
8005 the symbol table was read in to create the structured hierarchy
8006 required by coff. It changes each pointer to a symbol into the index
8007 into the symbol table of the asymbol.
8009 * `coff_write_symbols'
8010 This routine runs through the symbol table and patches up the
8011 symbols from their internal form into the coff way, calls the bit
8012 twiddlers, and writes out the table to the file.

8354 3.3.2.7 Writing relocations
8355 ...........................
8357 To write relocations, the back end steps though the canonical
8358 relocation table and create an `internal_reloc'. The symbol index to
8359 use is removed from the `offset' field in the symbol table supplied.
8360 The address comes directly from the sum of the section base address and
8361 the relocation offset; the type is dug directly from the howto field.
8362 Then the `internal_reloc' is swapped into the shape of an
8363 `external_reloc' and written out to disk.
8365 3.3.2.8 Reading linenumbers
8366 ...........................
8368 Creating the linenumber table is done by reading in the entire coff
8369 linenumber table, and creating another table for internal use.
8371 A coff linenumber table is structured so that each function is
8372 marked as having a line number of 0. Each line within the function is
8373 an offset from the first line in the function. The base of the line
8374 number information for the table is stored in the symbol associated
8375 with the function.
8377 Note: The PE format uses line number 0 for a flag indicating a new
8378 source file.
8380 The information is copied from the external to the internal table,
8381 and each symbol which marks a function is marked by pointing its...
8383 How does this work ?
8385 3.3.2.9 Reading relocations
8386 ...........................
8388 Coff relocations are easily transformed into the internal BFD form
8389 (`arelent').
8391 Reading a coff relocation table is done in the following stages:
8393 * Read the entire coff relocation table into memory.
8395 * Process each relocation in turn; first swap it from the external
8396 to the internal form.
8398 * Turn the symbol referenced in the relocation's symbol index into a
8399 pointer into the canonical symbol table. This table is the same
8400 as the one returned by a call to `bfd_canonicalize_symtab'. The
8401 back end will call that routine and save the result if a
8402 canonicalization hasn't been done.
8404 * The reloc index is turned into a pointer to a howto structure, in
8405 a back end specific way. For instance, the 386 and 960 use the
8406 `r_type' to directly produce an index into a howto table vector;
8407 the 88k subtracts a number from the `r_type' field and creates an
8408 addend field.

8413 3.4 ELF backends
8414 ================
8416 BFD support for ELF formats is being worked on. Currently, the best
8417 supported back ends are for sparc and i386 (running svr4 or Solaris 2).
8419 Documentation of the internals of the support code still needs to be
8420 written. The code is changing quickly enough that we haven't bothered
8421 yet.

8428 *Description*
8429 Helper functions for GDB to locate the string tables. Since BFD hides
8430 string tables from callers, GDB needs to use an internal hook to find
8431 them. Sun's .stabstr, in particular, isn't even pointed to by the
8432 .stab section, so ordinary mechanisms wouldn't work to find it, even if
8433 we had some.

8438 3.5 mmo backend
8439 ===============
8441 The mmo object format is used exclusively together with Professor
8442 Donald E. Knuth's educational 64-bit processor MMIX. The simulator
8443 `mmix' which is available at
8444 `http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz'
8445 understands this format. That package also includes a combined
8446 assembler and linker called `mmixal'. The mmo format has no advantages
8447 feature-wise compared to e.g. ELF. It is a simple non-relocatable
8448 object format with no support for archives or debugging information,
8449 except for symbol value information and line numbers (which is not yet
8450 implemented in BFD). See
8451 `http://www-cs-faculty.stanford.edu/~knuth/mmix.html' for more
8452 information about MMIX. The ELF format is used for intermediate object
8453 files in the BFD implementation.

8464 3.5.1 File layout
8465 -----------------
8467 The mmo file contents is not partitioned into named sections as with
8468 e.g. ELF. Memory areas is formed by specifying the location of the
8469 data that follows. Only the memory area `0x0000...00' to `0x01ff...ff'
8470 is executable, so it is used for code (and constants) and the area
8471 `0x2000...00' to `0x20ff...ff' is used for writable data. *Note mmo
8472 section mapping::.
8474 There is provision for specifying "special data" of 65536 different
8475 types. We use type 80 (decimal), arbitrarily chosen the same as the
8476 ELF `e_machine' number for MMIX, filling it with section information
8477 normally found in ELF objects. *Note mmo section mapping::.
8479 Contents is entered as 32-bit words, xor:ed over previous contents,
8480 always zero-initialized. A word that starts with the byte `0x98' forms
8481 a command called a `lopcode', where the next byte distinguished between
8482 the thirteen lopcodes. The two remaining bytes, called the `Y' and `Z'
8483 fields, or the `YZ' field (a 16-bit big-endian number), are used for
8484 various purposes different for each lopcode. As documented in
8485 `http://www-cs-faculty.stanford.edu/~knuth/mmixal-intro.ps.gz', the
8486 lopcodes are:
8488 `lop_quote'
8489 0x98000001. The next word is contents, regardless of whether it
8490 starts with 0x98 or not.
8492 `lop_loc'
8493 0x9801YYZZ, where `Z' is 1 or 2. This is a location directive,
8494 setting the location for the next data to the next 32-bit word
8495 (for Z = 1) or 64-bit word (for Z = 2), plus Y * 2^56. Normally
8496 `Y' is 0 for the text segment and 2 for the data segment.
8498 `lop_skip'
8499 0x9802YYZZ. Increase the current location by `YZ' bytes.
8501 `lop_fixo'
8502 0x9803YYZZ, where `Z' is 1 or 2. Store the current location as 64
8503 bits into the location pointed to by the next 32-bit (Z = 1) or
8504 64-bit (Z = 2) word, plus Y * 2^56.
8506 `lop_fixr'
8507 0x9804YYZZ. `YZ' is stored into the current location plus 2 - 4 *
8508 YZ.
8510 `lop_fixrx'
8511 0x980500ZZ. `Z' is 16 or 24. A value `L' derived from the
8512 following 32-bit word are used in a manner similar to `YZ' in
8513 lop_fixr: it is xor:ed into the current location minus 4 * L. The
8514 first byte of the word is 0 or 1. If it is 1, then L = (LOWEST 24
8515 BITS OF WORD) - 2^Z, if 0, then L = (LOWEST 24 BITS OF WORD).
8517 `lop_file'
8518 0x9806YYZZ. `Y' is the file number, `Z' is count of 32-bit words.
8519 Set the file number to `Y' and the line counter to 0. The next Z
8520 * 4 bytes contain the file name, padded with zeros if the count is
8521 not a multiple of four. The same `Y' may occur multiple times,
8522 but `Z' must be 0 for all but the first occurrence.
8524 `lop_line'
8525 0x9807YYZZ. `YZ' is the line number. Together with lop_file, it
8526 forms the source location for the next 32-bit word. Note that for
8527 each non-lopcode 32-bit word, line numbers are assumed incremented
8528 by one.
8530 `lop_spec'
8531 0x9808YYZZ. `YZ' is the type number. Data until the next lopcode
8532 other than lop_quote forms special data of type `YZ'. *Note mmo
8533 section mapping::.
8535 Other types than 80, (or type 80 with a content that does not
8536 parse) is stored in sections named `.MMIX.spec_data.N' where N is
8537 the `YZ'-type. The flags for such a sections say not to allocate
8538 or load the data. The vma is 0. Contents of multiple occurrences
8539 of special data N is concatenated to the data of the previous
8540 lop_spec Ns. The location in data or code at which the lop_spec
8541 occurred is lost.
8543 `lop_pre'
8544 0x980901ZZ. The first lopcode in a file. The `Z' field forms the
8545 length of header information in 32-bit words, where the first word
8546 tells the time in seconds since `00:00:00 GMT Jan 1 1970'.
8548 `lop_post'
8549 0x980a00ZZ. Z > 32. This lopcode follows after all
8550 content-generating lopcodes in a program. The `Z' field denotes
8551 the value of `rG' at the beginning of the program. The following
8552 256 - Z big-endian 64-bit words are loaded into global registers
8553 `$G' ... `$255'.
8555 `lop_stab'
8556 0x980b0000. The next-to-last lopcode in a program. Must follow
8557 immediately after the lop_post lopcode and its data. After this
8558 lopcode follows all symbols in a compressed format (*note
8559 Symbol-table::).
8561 `lop_end'
8562 0x980cYYZZ. The last lopcode in a program. It must follow the
8563 lop_stab lopcode and its data. The `YZ' field contains the number
8564 of 32-bit words of symbol table information after the preceding
8565 lop_stab lopcode.
8567 Note that the lopcode "fixups"; `lop_fixr', `lop_fixrx' and
8568 `lop_fixo' are not generated by BFD, but are handled. They are
8569 generated by `mmixal'.
8571 This trivial one-label, one-instruction file:
8573 :Main TRAP 1,2,3
8575 can be represented this way in mmo:
8577 0x98090101 - lop_pre, one 32-bit word with timestamp.
8578 <timestamp>
8579 0x98010002 - lop_loc, text segment, using a 64-bit address.

8602 3.5.2 Symbol table format
8603 -------------------------
8605 From mmixal.w (or really, the generated mmixal.tex) in
8606 `http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz'):
8607 "Symbols are stored and retrieved by means of a `ternary search trie',
8608 following ideas of Bentley and Sedgewick. (See ACM-SIAM Symp. on
8609 Discrete Algorithms `8' (1997), 360-369; R.Sedgewick, `Algorithms in C'
8610 (Reading, Mass. Addison-Wesley, 1998), `15.4'.) Each trie node stores
8611 a character, and there are branches to subtries for the cases where a
8612 given character is less than, equal to, or greater than the character
8613 in the trie. There also is a pointer to a symbol table entry if a
8614 symbol ends at the current node."
8616 So it's a tree encoded as a stream of bytes. The stream of bytes
8617 acts on a single virtual global symbol, adding and removing characters
8618 and signalling complete symbol points. Here, we read the stream and
8619 create symbols at the completion points.
8621 First, there's a control byte `m'. If any of the listed bits in `m'
8622 is nonzero, we execute what stands at the right, in the listed order:
8624 (MMO3_LEFT)
8625 0x40 - Traverse left trie.
8626 (Read a new command byte and recurse.)
8628 (MMO3_SYMBITS)
8629 0x2f - Read the next byte as a character and store it in the
8630 current character position; increment character position.
8631 Test the bits of `m':
8633 (MMO3_WCHAR)
8634 0x80 - The character is 16-bit (so read another byte,
8635 merge into current character.
8637 (MMO3_TYPEBITS)
8638 0xf - We have a complete symbol; parse the type, value
8639 and serial number and do what should be done
8640 with a symbol. The type and length information
8641 is in j = (m & 0xf).
8643 (MMO3_REGQUAL_BITS)
8644 j == 0xf: A register variable. The following
8645 byte tells which register.
8646 j <= 8: An absolute symbol. Read j bytes as the
8647 big-endian number the symbol equals.
8648 A j = 2 with two zero bytes denotes an
8649 unknown symbol.
8650 j > 8: As with j <= 8, but add (0x20 << 56)
8651 to the value in the following j - 8
8652 bytes.
8654 Then comes the serial number, as a variant of
8655 uleb128, but better named ubeb128:
8656 Read bytes and shift the previous value left 7
8657 (multiply by 128). Add in the new byte, repeat
8658 until a byte has bit 7 set. The serial number
8659 is the computed value minus 128.
8661 (MMO3_MIDDLE)
8662 0x20 - Traverse middle trie. (Read a new command byte
8663 and recurse.) Decrement character position.
8665 (MMO3_RIGHT)
8666 0x10 - Traverse right trie. (Read a new command byte and
8667 recurse.)
8669 Let's look again at the `lop_stab' for the trivial file (*note File
8670 layout::).
8672 0x980b0000 - lop_stab for ":Main" = 0, serial 1.
8673 0x203a4040
8674 0x10404020
8675 0x4d206120
8676 0x69016e00
8677 0x81000000
8679 This forms the trivial trie (note that the path between ":" and "M"
8680 is redundant):
8682 203a ":"
8683 40 /
8684 40 /
8685 10 \
8686 40 /
8687 40 /
8688 204d "M"
8689 2061 "a"
8690 2069 "i"
8691 016e "n" is the last character in a full symbol, and
8692 with a value represented in one byte.
8693 00 The value is 0.
8694 81 The serial number is 1.

8699 3.5.3 mmo section mapping
8700 -------------------------
8702 The implementation in BFD uses special data type 80 (decimal) to
8703 encapsulate and describe named sections, containing e.g. debug
8704 information. If needed, any datum in the encapsulation will be quoted
8705 using lop_quote. First comes a 32-bit word holding the number of
8706 32-bit words containing the zero-terminated zero-padded segment name.
8707 After the name there's a 32-bit word holding flags describing the
8708 section type. Then comes a 64-bit big-endian word with the section
8709 length (in bytes), then another with the section start address.
8710 Depending on the type of section, the contents might follow,
8711 zero-padded to 32-bit boundary. For a loadable section (such as data
8712 or code), the contents might follow at some later point, not
8713 necessarily immediately, as a lop_loc with the same start address as in
8714 the section description, followed by the contents. This in effect
8715 forms a descriptor that must be emitted before the actual contents.
8716 Sections described this way must not overlap.
8718 For areas that don't have such descriptors, synthetic sections are
8719 formed by BFD. Consecutive contents in the two memory areas
8720 `0x0000...00' to `0x01ff...ff' and `0x2000...00' to `0x20ff...ff' are
8721 entered in sections named `.text' and `.data' respectively. If an area
8722 is not otherwise described, but would together with a neighboring lower
8723 area be less than `0x40000000' bytes long, it is joined with the lower
8724 area and the gap is zero-filled. For other cases, a new section is
8725 formed, named `.MMIX.sec.N'. Here, N is a number, a running count
8726 through the mmo file, starting at 0.
8728 A loadable section specified as:
8730 .section secname,"ax"
8731 TETRA 1,2,3,4,-1,-2009
8732 BYTE 80
8734 and linked to address `0x4', is represented by the sequence:
8736 0x98080050 - lop_spec 80
8737 0x00000002 - two 32-bit words for the section name
8738 0x7365636e - "secn"
8739 0x616d6500 - "ame\0"
8740 0x00000033 - flags CODE, READONLY, LOAD, ALLOC
8741 0x00000000 - high 32 bits of section length
8742 0x0000001c - section length is 28 bytes; 6 * 4 + 1 + alignment to 32 bits
8743 0x00000000 - high 32 bits of section address
8744 0x00000004 - section address is 4
8745 0x98010002 - 64 bits with address of following data
8746 0x00000000 - high 32 bits of address
8747 0x00000004 - low 32 bits: data starts at address 4
8748 0x00000001 - 1
8749 0x00000002 - 2
8750 0x00000003 - 3
8751 0x00000004 - 4
8752 0xffffffff - -1
8753 0xfffff827 - -2009
8754 0x50000000 - 80 as a byte, padded with zeros.
8756 Note that the lop_spec wrapping does not include the section
8757 contents. Compare this to a non-loaded section specified as:
8759 .section thirdsec
8760 TETRA 200001,100002
8761 BYTE 38,40
8763 This, when linked to address `0x200000000000001c', is represented by:
8765 0x98080050 - lop_spec 80
8766 0x00000002 - two 32-bit words for the section name
8767 0x7365636e - "thir"
8768 0x616d6500 - "dsec"
8769 0x00000010 - flag READONLY
8770 0x00000000 - high 32 bits of section length
8771 0x0000000c - section length is 12 bytes; 2 * 4 + 2 + alignment to 32 bits
8772 0x20000000 - high 32 bits of address
8773 0x0000001c - low 32 bits of address 0x200000000000001c
8774 0x00030d41 - 200001
8775 0x000186a2 - 100002
8776 0x26280000 - 38, 40 as bytes, padded with zeros
8778 For the latter example, the section contents must not be loaded in
8779 memory, and is therefore specified as part of the special data. The
8780 address is usually unimportant but might provide information for e.g.
8781 the DWARF 2 debugging format.

8787 *****************************************
8789 Version 1.1, March 2000
8791 Copyright (C) 2000, 2003 Free Software Foundation, Inc.
8792 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
8794 Everyone is permitted to copy and distribute verbatim copies
8795 of this license document, but changing it is not allowed.
8798 0. PREAMBLE
8800 The purpose of this License is to make a manual, textbook, or other
8801 written document "free" in the sense of freedom: to assure everyone
8802 the effective freedom to copy and redistribute it, with or without
8803 modifying it, either commercially or noncommercially. Secondarily,
8804 this License preserves for the author and publisher a way to get
8805 credit for their work, while not being considered responsible for
8806 modifications made by others.
8808 This License is a kind of "copyleft", which means that derivative
8809 works of the document must themselves be free in the same sense.
8810 It complements the GNU General Public License, which is a copyleft
8811 license designed for free software.
8813 We have designed this License in order to use it for manuals for
8814 free software, because free software needs free documentation: a
8815 free program should come with manuals providing the same freedoms
8816 that the software does. But this License is not limited to
8817 software manuals; it can be used for any textual work, regardless
8818 of subject matter or whether it is published as a printed book.
8819 We recommend this License principally for works whose purpose is
8820 instruction or reference.
8823 1. APPLICABILITY AND DEFINITIONS
8825 This License applies to any manual or other work that contains a
8826 notice placed by the copyright holder saying it can be distributed
8827 under the terms of this License. The "Document", below, refers to
8828 any such manual or work. Any member of the public is a licensee,
8829 and is addressed as "you."
8831 A "Modified Version" of the Document means any work containing the
8832 Document or a portion of it, either copied verbatim, or with
8833 modifications and/or translated into another language.
8835 A "Secondary Section" is a named appendix or a front-matter
8836 section of the Document that deals exclusively with the
8837 relationship of the publishers or authors of the Document to the
8838 Document's overall subject (or to related matters) and contains
8839 nothing that could fall directly within that overall subject.
8840 (For example, if the Document is in part a textbook of
8841 mathematics, a Secondary Section may not explain any mathematics.)
8842 The relationship could be a matter of historical connection with
8843 the subject or with related matters, or of legal, commercial,
8844 philosophical, ethical or political position regarding them.
8846 The "Invariant Sections" are certain Secondary Sections whose
8847 titles are designated, as being those of Invariant Sections, in
8848 the notice that says that the Document is released under this
8849 License.
8851 The "Cover Texts" are certain short passages of text that are
8852 listed, as Front-Cover Texts or Back-Cover Texts, in the notice
8853 that says that the Document is released under this License.
8855 A "Transparent" copy of the Document means a machine-readable copy,
8856 represented in a format whose specification is available to the
8857 general public, whose contents can be viewed and edited directly
8858 and straightforwardly with generic text editors or (for images
8859 composed of pixels) generic paint programs or (for drawings) some
8860 widely available drawing editor, and that is suitable for input to
8861 text formatters or for automatic translation to a variety of
8862 formats suitable for input to text formatters. A copy made in an
8863 otherwise Transparent file format whose markup has been designed
8864 to thwart or discourage subsequent modification by readers is not
8865 Transparent. A copy that is not "Transparent" is called "Opaque."
8867 Examples of suitable formats for Transparent copies include plain
8868 ASCII without markup, Texinfo input format, LaTeX input format,
8869 SGML or XML using a publicly available DTD, and
8870 standard-conforming simple HTML designed for human modification.
8871 Opaque formats include PostScript, PDF, proprietary formats that
8872 can be read and edited only by proprietary word processors, SGML
8873 or XML for which the DTD and/or processing tools are not generally
8874 available, and the machine-generated HTML produced by some word
8875 processors for output purposes only.
8877 The "Title Page" means, for a printed book, the title page itself,
8878 plus such following pages as are needed to hold, legibly, the
8879 material this License requires to appear in the title page. For
8880 works in formats which do not have any title page as such, "Title
8881 Page" means the text near the most prominent appearance of the
8882 work's title, preceding the beginning of the body of the text.
8884 2. VERBATIM COPYING
8886 You may copy and distribute the Document in any medium, either
8887 commercially or noncommercially, provided that this License, the
8888 copyright notices, and the license notice saying this License
8889 applies to the Document are reproduced in all copies, and that you
8890 add no other conditions whatsoever to those of this License. You
8891 may not use technical measures to obstruct or control the reading
8892 or further copying of the copies you make or distribute. However,
8893 you may accept compensation in exchange for copies. If you
8894 distribute a large enough number of copies you must also follow
8895 the conditions in section 3.
8897 You may also lend copies, under the same conditions stated above,
8898 and you may publicly display copies.
8900 3. COPYING IN QUANTITY
8902 If you publish printed copies of the Document numbering more than
8903 100, and the Document's license notice requires Cover Texts, you
8904 must enclose the copies in covers that carry, clearly and legibly,
8905 all these Cover Texts: Front-Cover Texts on the front cover, and
8906 Back-Cover Texts on the back cover. Both covers must also clearly
8907 and legibly identify you as the publisher of these copies. The
8908 front cover must present the full title with all words of the
8909 title equally prominent and visible. You may add other material
8910 on the covers in addition. Copying with changes limited to the
8911 covers, as long as they preserve the title of the Document and
8912 satisfy these conditions, can be treated as verbatim copying in
8913 other respects.
8915 If the required texts for either cover are too voluminous to fit
8916 legibly, you should put the first ones listed (as many as fit
8917 reasonably) on the actual cover, and continue the rest onto
8918 adjacent pages.
8920 If you publish or distribute Opaque copies of the Document
8921 numbering more than 100, you must either include a
8922 machine-readable Transparent copy along with each Opaque copy, or
8923 state in or with each Opaque copy a publicly-accessible
8924 computer-network location containing a complete Transparent copy
8925 of the Document, free of added material, which the general
8926 network-using public has access to download anonymously at no
8927 charge using public-standard network protocols. If you use the
8928 latter option, you must take reasonably prudent steps, when you
8929 begin distribution of Opaque copies in quantity, to ensure that
8930 this Transparent copy will remain thus accessible at the stated
8931 location until at least one year after the last time you
8932 distribute an Opaque copy (directly or through your agents or
8933 retailers) of that edition to the public.
8935 It is requested, but not required, that you contact the authors of
8936 the Document well before redistributing any large number of
8937 copies, to give them a chance to provide you with an updated
8938 version of the Document.
8940 4. MODIFICATIONS
8942 You may copy and distribute a Modified Version of the Document
8943 under the conditions of sections 2 and 3 above, provided that you
8944 release the Modified Version under precisely this License, with
8945 the Modified Version filling the role of the Document, thus
8946 licensing distribution and modification of the Modified Version to
8947 whoever possesses a copy of it. In addition, you must do these
8948 things in the Modified Version:
8950 A. Use in the Title Page (and on the covers, if any) a title
8951 distinct from that of the Document, and from those of previous
8952 versions (which should, if there were any, be listed in the
8953 History section of the Document). You may use the same title
8954 as a previous version if the original publisher of that version
8955 gives permission.
8956 B. List on the Title Page, as authors, one or more persons or
8957 entities responsible for authorship of the modifications in the
8958 Modified Version, together with at least five of the principal
8959 authors of the Document (all of its principal authors, if it
8960 has less than five).
8961 C. State on the Title page the name of the publisher of the
8962 Modified Version, as the publisher.
8963 D. Preserve all the copyright notices of the Document.
8964 E. Add an appropriate copyright notice for your modifications
8965 adjacent to the other copyright notices.
8966 F. Include, immediately after the copyright notices, a license
8967 notice giving the public permission to use the Modified Version
8968 under the terms of this License, in the form shown in the
8969 Addendum below.
8970 G. Preserve in that license notice the full lists of Invariant
8971 Sections and required Cover Texts given in the Document's
8972 license notice.
8973 H. Include an unaltered copy of this License.
8974 I. Preserve the section entitled "History", and its title, and add
8975 to it an item stating at least the title, year, new authors, and
8976 publisher of the Modified Version as given on the Title Page.
8977 If there is no section entitled "History" in the Document,
8978 create one stating the title, year, authors, and publisher of
8979 the Document as given on its Title Page, then add an item
8980 describing the Modified Version as stated in the previous
8981 sentence.
8982 J. Preserve the network location, if any, given in the Document for
8983 public access to a Transparent copy of the Document, and
8984 likewise the network locations given in the Document for
8985 previous versions it was based on. These may be placed in the
8986 "History" section. You may omit a network location for a work
8987 that was published at least four years before the Document
8988 itself, or if the original publisher of the version it refers
8989 to gives permission.
8990 K. In any section entitled "Acknowledgements" or "Dedications",
8991 preserve the section's title, and preserve in the section all the
8992 substance and tone of each of the contributor acknowledgements
8993 and/or dedications given therein.
8994 L. Preserve all the Invariant Sections of the Document,
8995 unaltered in their text and in their titles. Section numbers
8996 or the equivalent are not considered part of the section titles.
8997 M. Delete any section entitled "Endorsements." Such a section
8998 may not be included in the Modified Version.
8999 N. Do not retitle any existing section as "Endorsements" or to
9000 conflict in title with any Invariant Section.
9002 If the Modified Version includes new front-matter sections or
9003 appendices that qualify as Secondary Sections and contain no
9004 material copied from the Document, you may at your option
9005 designate some or all of these sections as invariant. To do this,
9006 add their titles to the list of Invariant Sections in the Modified
9007 Version's license notice. These titles must be distinct from any
9008 other section titles.
9010 You may add a section entitled "Endorsements", provided it contains
9011 nothing but endorsements of your Modified Version by various
9012 parties-for example, statements of peer review or that the text has
9013 been approved by an organization as the authoritative definition
9014 of a standard.
9016 You may add a passage of up to five words as a Front-Cover Text,
9017 and a passage of up to 25 words as a Back-Cover Text, to the end
9018 of the list of Cover Texts in the Modified Version. Only one
9019 passage of Front-Cover Text and one of Back-Cover Text may be
9020 added by (or through arrangements made by) any one entity. If the
9021 Document already includes a cover text for the same cover,
9022 previously added by you or by arrangement made by the same entity
9023 you are acting on behalf of, you may not add another; but you may
9024 replace the old one, on explicit permission from the previous
9025 publisher that added the old one.
9027 The author(s) and publisher(s) of the Document do not by this
9028 License give permission to use their names for publicity for or to
9029 assert or imply endorsement of any Modified Version.
9031 5. COMBINING DOCUMENTS
9033 You may combine the Document with other documents released under
9034 this License, under the terms defined in section 4 above for
9035 modified versions, provided that you include in the combination
9036 all of the Invariant Sections of all of the original documents,
9037 unmodified, and list them all as Invariant Sections of your
9038 combined work in its license notice.
9040 The combined work need only contain one copy of this License, and
9041 multiple identical Invariant Sections may be replaced with a single
9042 copy. If there are multiple Invariant Sections with the same name
9043 but different contents, make the title of each such section unique
9044 by adding at the end of it, in parentheses, the name of the
9045 original author or publisher of that section if known, or else a
9046 unique number. Make the same adjustment to the section titles in
9047 the list of Invariant Sections in the license notice of the
9048 combined work.
9050 In the combination, you must combine any sections entitled
9051 "History" in the various original documents, forming one section
9052 entitled "History"; likewise combine any sections entitled
9053 "Acknowledgements", and any sections entitled "Dedications." You
9054 must delete all sections entitled "Endorsements."
9056 6. COLLECTIONS OF DOCUMENTS
9058 You may make a collection consisting of the Document and other
9059 documents released under this License, and replace the individual
9060 copies of this License in the various documents with a single copy
9061 that is included in the collection, provided that you follow the
9062 rules of this License for verbatim copying of each of the
9063 documents in all other respects.
9065 You may extract a single document from such a collection, and
9066 distribute it individually under this License, provided you insert
9067 a copy of this License into the extracted document, and follow
9068 this License in all other respects regarding verbatim copying of
9069 that document.
9071 7. AGGREGATION WITH INDEPENDENT WORKS
9073 A compilation of the Document or its derivatives with other
9074 separate and independent documents or works, in or on a volume of
9075 a storage or distribution medium, does not as a whole count as a
9076 Modified Version of the Document, provided no compilation
9077 copyright is claimed for the compilation. Such a compilation is
9078 called an "aggregate", and this License does not apply to the
9079 other self-contained works thus compiled with the Document, on
9080 account of their being thus compiled, if they are not themselves
9081 derivative works of the Document.
9083 If the Cover Text requirement of section 3 is applicable to these
9084 copies of the Document, then if the Document is less than one
9085 quarter of the entire aggregate, the Document's Cover Texts may be
9086 placed on covers that surround only the Document within the
9087 aggregate. Otherwise they must appear on covers around the whole
9088 aggregate.
9090 8. TRANSLATION
9092 Translation is considered a kind of modification, so you may
9093 distribute translations of the Document under the terms of section
9094 4. Replacing Invariant Sections with translations requires special
9095 permission from their copyright holders, but you may include
9096 translations of some or all Invariant Sections in addition to the
9097 original versions of these Invariant Sections. You may include a
9098 translation of this License provided that you also include the
9099 original English version of this License. In case of a
9100 disagreement between the translation and the original English
9101 version of this License, the original English version will prevail.
9103 9. TERMINATION
9105 You may not copy, modify, sublicense, or distribute the Document
9106 except as expressly provided for under this License. Any other
9107 attempt to copy, modify, sublicense or distribute the Document is
9108 void, and will automatically terminate your rights under this
9109 License. However, parties who have received copies, or rights,
9110 from you under this License will not have their licenses
9111 terminated so long as such parties remain in full compliance.
9113 10. FUTURE REVISIONS OF THIS LICENSE
9115 The Free Software Foundation may publish new, revised versions of
9116 the GNU Free Documentation License from time to time. Such new
9117 versions will be similar in spirit to the present version, but may
9118 differ in detail to address new problems or concerns. See
9119 http://www.gnu.org/copyleft/.
9121 Each version of the License is given a distinguishing version
9122 number. If the Document specifies that a particular numbered
9123 version of this License "or any later version" applies to it, you
9124 have the option of following the terms and conditions either of
9125 that specified version or of any later version that has been
9126 published (not as a draft) by the Free Software Foundation. If
9127 the Document does not specify a version number of this License,
9128 you may choose any version ever published (not as a draft) by the
9129 Free Software Foundation.
9132 ADDENDUM: How to use this License for your documents
9133 ====================================================
9135 To use this License in a document you have written, include a copy of
9136 the License in the document and put the following copyright and license
9137 notices just after the title page:
9139 Copyright (C) YEAR YOUR NAME.
9140 Permission is granted to copy, distribute and/or modify this document
9141 under the terms of the GNU Free Documentation License, Version 1.1
9142 or any later version published by the Free Software Foundation;
9143 with the Invariant Sections being LIST THEIR TITLES, with the
9144 Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
9145 A copy of the license is included in the section entitled "GNU
9146 Free Documentation License."
9148 If you have no Invariant Sections, write "with no Invariant Sections"
9149 instead of saying which ones are invariant. If you have no Front-Cover
9150 Texts, write "no Front-Cover Texts" instead of "Front-Cover Texts being
9151 LIST"; likewise for Back-Cover Texts.
9153 If your document contains nontrivial examples of program code, we
9154 recommend releasing these examples in parallel under your choice of
9155 free software license, such as the GNU General Public License, to
9156 permit their use in free software.
