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).

568 2.2 Error reporting
569 ===================
571 Most BFD functions return nonzero on success (check their individual
572 documentation for precise semantics). On an error, they call
573 `bfd_set_error' to set an error condition that callers can check by
574 calling `bfd_get_error'. If that returns `bfd_error_system_call', then
575 check `errno'.
577 The easiest way to report a BFD error to the user is to use
578 `bfd_perror'.
580 2.2.1 Type `bfd_error_type'

626 *Description*
627 Set the BFD error condition to be ERROR_TAG. If ERROR_TAG is
628 bfd_error_on_input, then this function takes two more parameters, the
629 input bfd where the error occurred, and the bfd_error_type error.
631 2.2.1.3 `bfd_errmsg'
632 ....................
634 *Synopsis*
635 const char *bfd_errmsg (bfd_error_type error_tag);
636 *Description*

638 ERROR_TAG is `bfd_error_system_call'.
640 2.2.1.4 `bfd_perror'
641 ....................
643 *Synopsis*
644 void bfd_perror (const char *message);
645 *Description*
646 Print to the standard error stream a string describing the last BFD
647 error that occurred, or the last system error if the last BFD error was
648 a system call failure. If MESSAGE is non-NULL and non-empty, the error
649 string printed is preceded by MESSAGE, a colon, and a space. It is
650 followed by a newline.
652 2.2.2 BFD error handler
653 -----------------------
655 Some BFD functions want to print messages describing the problem. They
656 call a BFD error handler function. This function may be overridden by
657 the program.
659 The BFD error handler acts like printf.
662 typedef void (*bfd_error_handler_type) (const char *, ...);
664 2.2.2.1 `bfd_set_error_handler'
665 ...............................
667 *Synopsis*
668 bfd_error_handler_type bfd_set_error_handler (bfd_error_handler_type);
669 *Description*
670 Set the BFD error handler function. Returns the previous function.
672 2.2.2.2 `bfd_set_error_program_name'

675 *Synopsis*
676 void bfd_set_error_program_name (const char *);
677 *Description*
678 Set the program name to use when printing a BFD error. This is printed
679 before the error message followed by a colon and space. The string
680 must not be changed after it is passed to this function.

690 2.3 Miscellaneous
691 =================
693 2.3.1 Miscellaneous functions
694 -----------------------------
696 2.3.1.1 `bfd_get_reloc_upper_bound'

701 *Description*
702 Return the number of bytes required to store the relocation information
703 associated with section SECT attached to bfd ABFD. If an error occurs,
704 return -1.
706 2.3.1.2 `bfd_canonicalize_reloc'
707 ................................
709 *Synopsis*
710 long bfd_canonicalize_reloc
711 (bfd *abfd, asection *sec, arelent **loc, asymbol **syms);
712 *Description*
713 Call the back end associated with the open BFD ABFD and translate the
714 external form of the relocation information attached to SEC into the
715 internal canonical form. Place the table into memory at LOC, which has
716 been preallocated, usually by a call to `bfd_get_reloc_upper_bound'.
717 Returns the number of relocs, or -1 on error.
719 The SYMS table is also needed for horrible internal magic reasons.
721 2.3.1.3 `bfd_set_reloc'
722 .......................
724 *Synopsis*
725 void bfd_set_reloc
726 (bfd *abfd, asection *sec, arelent **rel, unsigned int count);
727 *Description*
728 Set the relocation pointer and count within section SEC to the values
729 REL and COUNT. The argument ABFD is ignored.
731 2.3.1.4 `bfd_set_file_flags'
732 ............................
734 *Synopsis*
735 bfd_boolean bfd_set_file_flags (bfd *abfd, flagword flags);
736 *Description*
737 Set the flag word in the BFD ABFD to the value FLAGS.
739 Possible errors are:
740 * `bfd_error_wrong_format' - The target bfd was not of object format.
742 * `bfd_error_invalid_operation' - The target bfd was open for
743 reading.
745 * `bfd_error_invalid_operation' - The flag word contained a bit
746 which was not applicable to the type of file. E.g., an attempt
747 was made to set the `D_PAGED' bit on a BFD format which does not
748 support demand paging.
750 2.3.1.5 `bfd_get_arch_size'
751 ...........................
753 *Synopsis*
754 int bfd_get_arch_size (bfd *abfd);
755 *Description*
756 Returns the architecture address size, in bits, as determined by the
757 object file's format. For ELF, this information is included in the
758 header.
760 *Returns*
761 Returns the arch size in bits if known, `-1' otherwise.
763 2.3.1.6 `bfd_get_sign_extend_vma'
764 .................................
766 *Synopsis*
767 int bfd_get_sign_extend_vma (bfd *abfd);
768 *Description*
769 Indicates if the target architecture "naturally" sign extends an
770 address. Some architectures implicitly sign extend address values when
771 they are converted to types larger than the size of an address. For
772 instance, bfd_get_start_address() will return an address sign extended
773 to fill a bfd_vma when this is the case.
775 *Returns*
776 Returns `1' if the target architecture is known to sign extend
777 addresses, `0' if the target architecture is known to not sign extend
778 addresses, and `-1' otherwise.
780 2.3.1.7 `bfd_set_start_address'
781 ...............................
783 *Synopsis*
784 bfd_boolean bfd_set_start_address (bfd *abfd, bfd_vma vma);
785 *Description*
786 Make VMA the entry point of output BFD ABFD.
788 *Returns*
789 Returns `TRUE' on success, `FALSE' otherwise.
791 2.3.1.8 `bfd_get_gp_size'
792 .........................
794 *Synopsis*
795 unsigned int bfd_get_gp_size (bfd *abfd);
796 *Description*
797 Return the maximum size of objects to be optimized using the GP
798 register under MIPS ECOFF. This is typically set by the `-G' argument
799 to the compiler, assembler or linker.
801 2.3.1.9 `bfd_set_gp_size'
802 .........................
804 *Synopsis*
805 void bfd_set_gp_size (bfd *abfd, unsigned int i);
806 *Description*
807 Set the maximum size of objects to be optimized using the GP register
808 under ECOFF or MIPS ELF. This is typically set by the `-G' argument to
809 the compiler, assembler or linker.
811 2.3.1.10 `bfd_scan_vma'
812 .......................
814 *Synopsis*
815 bfd_vma bfd_scan_vma (const char *string, const char **end, int base);
816 *Description*
817 Convert, like `strtoul', a numerical expression STRING into a `bfd_vma'
818 integer, and return that integer. (Though without as many bells and
819 whistles as `strtoul'.) The expression is assumed to be unsigned
820 (i.e., positive). If given a BASE, it is used as the base for
821 conversion. A base of 0 causes the function to interpret the string in
822 hex if a leading "0x" or "0X" is found, otherwise in octal if a leading
823 zero is found, otherwise in decimal.
825 If the value would overflow, the maximum `bfd_vma' value is returned.
827 2.3.1.11 `bfd_copy_private_header_data'
828 .......................................
830 *Synopsis*
831 bfd_boolean bfd_copy_private_header_data (bfd *ibfd, bfd *obfd);
832 *Description*
833 Copy private BFD header information from the BFD IBFD to the the BFD
834 OBFD. This copies information that may require sections to exist, but
835 does not require symbol tables. Return `true' on success, `false' on
836 error. Possible error returns are:
838 * `bfd_error_no_memory' - Not enough memory exists to create private
839 data for OBFD.

992 *Description*
993 When more than one machine code number is available for the same
994 machine type, this function can be used to switch between the preferred
995 one (alternative == 0) and any others. Currently, only ELF supports
996 this feature, with up to two alternate machine codes.

1011 ............................
1013 *Synopsis*
1014 bfd_boolean bfd_preserve_save (bfd *, struct bfd_preserve *);
1015 *Description*
1016 When testing an object for compatibility with a particular target
1017 back-end, the back-end object_p function needs to set up certain fields
1018 in the bfd on successfully recognizing the object. This typically
1019 happens in a piecemeal fashion, with failures possible at many points.
1020 On failure, the bfd is supposed to be restored to its initial state,
1021 which is virtually impossible. However, restoring a subset of the bfd
1022 state works in practice. This function stores the subset and
1023 reinitializes the bfd.
1025 2.3.1.18 `bfd_preserve_restore'
1026 ...............................
1028 *Synopsis*
1029 void bfd_preserve_restore (bfd *, struct bfd_preserve *);
1030 *Description*
1031 This function restores bfd state saved by bfd_preserve_save. If MARKER
1032 is non-NULL in struct bfd_preserve then that block and all subsequently
1033 bfd_alloc'd memory is freed.
1035 2.3.1.19 `bfd_preserve_finish'
1036 ..............................
1038 *Synopsis*
1039 void bfd_preserve_finish (bfd *, struct bfd_preserve *);
1040 *Description*
1041 This function should be called when the bfd state saved by
1042 bfd_preserve_save is no longer needed. ie. when the back-end object_p
1043 function returns with success.

1086 .......................
1088 *Synopsis*
1089 char *bfd_demangle (bfd *, const char *, int);
1090 *Description*
1091 Wrapper around cplus_demangle. Strips leading underscores and other
1092 such chars that would otherwise confuse the demangler. If passed a g++
1093 v3 ABI mangled name, returns a buffer allocated with malloc holding the
1094 demangled name. Returns NULL otherwise and on memory alloc failure.
1096 2.3.1.25 `struct bfd_iovec'

1129 2.3.1.26 `bfd_get_mtime'
1130 ........................
1132 *Synopsis*
1133 long bfd_get_mtime (bfd *abfd);
1134 *Description*
1135 Return the file modification time (as read from the file system, or
1136 from the archive header for archive members).
1138 2.3.1.27 `bfd_get_size'
1139 .......................
1141 *Synopsis*
1142 file_ptr bfd_get_size (bfd *abfd);
1143 *Description*
1144 Return the file size (as read from file system) for the file associated
1145 with BFD ABFD.
1147 The initial motivation for, and use of, this routine is not so we
1148 can get the exact size of the object the BFD applies to, since that
1149 might not be generally possible (archive members for example). It
1150 would be ideal if someone could eventually modify it so that such
1151 results were guaranteed.
1153 Instead, we want to ask questions like "is this NNN byte sized
1154 object I'm about to try read from file offset YYY reasonable?" As as
1155 example of where we might do this, some object formats use string
1156 tables for which the first `sizeof (long)' bytes of the table contain
1157 the size of the table itself, including the size bytes. If an
1158 application tries to read what it thinks is one of these string tables,
1159 without some way to validate the size, and for some reason the size is
1160 wrong (byte swapping error, wrong location for the string table, etc.),
1161 the only clue is likely to be a read error when it tries to read the
1162 table, or a "virtual memory exhausted" error when it tries to allocate

1197 2.4 Memory Usage
1198 ================
1200 BFD keeps all of its internal structures in obstacks. There is one
1201 obstack per open BFD file, into which the current state is stored. When
1202 a BFD is closed, the obstack is deleted, and so everything which has
1203 been allocated by BFD for the closing file is thrown away.
1205 BFD does not free anything created by an application, but pointers
1206 into `bfd' structures become invalid on a `bfd_close'; for example,
1207 after a `bfd_close' the vector passed to `bfd_canonicalize_symtab' is
1208 still around, since it has been allocated by the application, but the
1209 data that it pointed to are lost.
1211 The general rule is to not close a BFD until all operations dependent
1212 upon data from the BFD have been completed, or all the data from within
1213 the file has been copied. To help with the management of memory, there
1214 is a function (`bfd_alloc_size') which returns the number of bytes in
1215 obstacks associated with the supplied BFD. This could be used to select
1216 the greediest open BFD, close it to reclaim the memory, perform some
1217 operation and reopen the BFD again, to get a fresh copy of the data
1218 structures.

1243 2.6 Sections
1244 ============
1246 The raw data contained within a BFD is maintained through the section
1247 abstraction. A single BFD may have any number of sections. It keeps
1248 hold of them by pointing to the first; each one points to the next in
1249 the list.
1251 Sections are supported in BFD in `section.c'.

1263 2.6.1 Section input
1264 -------------------
1266 When a BFD is opened for reading, the section structures are created
1267 and attached to the BFD.
1269 Each section has a name which describes the section in the outside
1270 world--for example, `a.out' would contain at least three sections,
1271 called `.text', `.data' and `.bss'.
1273 Names need not be unique; for example a COFF file may have several
1274 sections named `.data'.
1276 Sometimes a BFD will contain more than the "natural" number of
1277 sections. A back end may attach other sections containing constructor
1278 data, or an application may add a section (using `bfd_make_section') to
1279 the sections attached to an already open BFD. For example, the linker
1280 creates an extra section `COMMON' for each input file's BFD to hold
1281 information about common storage.
1283 The raw data is not necessarily read in when the section descriptor
1284 is created. Some targets may leave the data in place until a
1285 `bfd_get_section_contents' call is made. Other back ends may read in
1286 all the data at once. For example, an S-record file has to be read
1287 once to determine the size of the data. An IEEE-695 file doesn't
1288 contain raw data in sections, but data and relocation expressions
1289 intermixed, so the data area has to be parsed to get out the data and
1290 relocations.
1292 \x1f
1293 File: bfd.info, Node: Section Output, Next: typedef asection, Prev: Section Input, Up: Sections
1295 2.6.2 Section output
1296 --------------------
1298 To write a new object style BFD, the various sections to be written
1299 have to be created. They are attached to the BFD in the same way as
1300 input sections; data is written to the sections using
1301 `bfd_set_section_contents'.
1303 Any program that creates or combines sections (e.g., the assembler
1304 and linker) must use the `asection' fields `output_section' and
1305 `output_offset' to indicate the file sections to which each section
1306 must be written. (If the section is being created from scratch,
1307 `output_section' should probably point to the section itself and
1308 `output_offset' should probably be zero.)
1310 The data to be written comes from input sections attached (via
1311 `output_section' pointers) to the output sections. The output section
1312 structure can be considered a filter for the input section: the output
1313 section determines the vma of the output data and the name, but the
1314 input section determines the offset into the output section of the data
1315 to be written.
1317 E.g., to create a section "O", starting at 0x100, 0x123 long,
1318 containing two subsections, "A" at offset 0x0 (i.e., at vma 0x100) and
1319 "B" at offset 0x20 (i.e., at vma 0x120) the `asection' structures would
1320 look like:
1322 section name "A"
1323 output_offset 0x00
1324 size 0x20
1325 output_section -----------> section name "O"
1326 | vma 0x100
1327 section name "B" | size 0x123
1328 output_offset 0x20 |
1329 size 0x103 |
1330 output_section --------|
1332 2.6.3 Link orders
1333 -----------------
1335 The data within a section is stored in a "link_order". These are much
1336 like the fixups in `gas'. The link_order abstraction allows a section
1337 to grow and shrink within itself.
1339 A link_order knows how big it is, and which is the next link_order
1340 and where the raw data for it is; it also points to a list of
1341 relocations which apply to it.
1343 The link_order is used by the linker to perform relaxing on final
1344 code. The compiler creates code which is as big as necessary to make
1345 it work without relaxing, and the user can select whether to relax.
1346 Sometimes relaxing takes a lot of time. The linker runs around the
1347 relocations to see if any are attached to data which can be shrunk, if
1348 so it does it on a link_order by link_order basis.

1907 2.6.5 Section prototypes
1908 ------------------------
1910 These are the functions exported by the section handling part of BFD.
1912 2.6.5.1 `bfd_section_list_clear'
1913 ................................
1915 *Synopsis*
1916 void bfd_section_list_clear (bfd *);
1917 *Description*
1918 Clears the section list, and also resets the section count and hash
1919 table entries.
1921 2.6.5.2 `bfd_get_section_by_name'
1922 .................................
1924 *Synopsis*
1925 asection *bfd_get_section_by_name (bfd *abfd, const char *name);
1926 *Description*
1927 Run through ABFD and return the one of the `asection's whose name
1928 matches NAME, otherwise `NULL'. *Note Sections::, for more information.
1930 This should only be used in special cases; the normal way to process
1931 all sections of a given name is to use `bfd_map_over_sections' and
1932 `strcmp' on the name (or better yet, base it on the section flags or
1933 something else) for each section.
1935 2.6.5.3 `bfd_get_section_by_name_if'
1936 ....................................
1938 *Synopsis*
1939 asection *bfd_get_section_by_name_if
1940 (bfd *abfd,
1941 const char *name,
1942 bfd_boolean (*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 whose name matches NAME, passing OBJ as an argument. The function
1947 will be called as if by
1949 func (abfd, the_section, obj);
1951 It returns the first section for which FUNC returns true, otherwise
1952 `NULL'.
1954 2.6.5.4 `bfd_get_unique_section_name'
1955 .....................................
1957 *Synopsis*
1958 char *bfd_get_unique_section_name
1959 (bfd *abfd, const char *templat, int *count);
1960 *Description*
1961 Invent a section name that is unique in ABFD by tacking a dot and a
1962 digit suffix onto the original TEMPLAT. If COUNT is non-NULL, then it
1963 specifies the first number tried as a suffix to generate a unique name.
1964 The value pointed to by COUNT will be incremented in this case.
1966 2.6.5.5 `bfd_make_section_old_way'
1967 ..................................
1969 *Synopsis*
1970 asection *bfd_make_section_old_way (bfd *abfd, const char *name);
1971 *Description*
1972 Create a new empty section called NAME and attach it to the end of the
1973 chain of sections for the BFD ABFD. An attempt to create a section with
1974 a name which is already in use returns its pointer without changing the
1975 section chain.
1977 It has the funny name since this is the way it used to be before it
1978 was rewritten....
1980 Possible errors are:
1981 * `bfd_error_invalid_operation' - If output has already started for
1982 this BFD.
1984 * `bfd_error_no_memory' - If memory allocation fails.
1986 2.6.5.6 `bfd_make_section_anyway_with_flags'
1987 ............................................
1989 *Synopsis*
1990 asection *bfd_make_section_anyway_with_flags
1991 (bfd *abfd, const char *name, flagword flags);
1992 *Description*
1993 Create a new empty section called NAME and attach it to the end of the
1994 chain of sections for ABFD. Create a new section even if there is
1995 already a section with that name. Also set the attributes of the new
1996 section to the value FLAGS.
1998 Return `NULL' and set `bfd_error' on error; possible errors are:
1999 * `bfd_error_invalid_operation' - If output has already started for
2000 ABFD.
2002 * `bfd_error_no_memory' - If memory allocation fails.
2004 2.6.5.7 `bfd_make_section_anyway'
2005 .................................
2007 *Synopsis*
2008 asection *bfd_make_section_anyway (bfd *abfd, const char *name);
2009 *Description*
2010 Create a new empty section called NAME and attach it to the end of the
2011 chain of sections for ABFD. Create a new section even if there is
2012 already a section with that name.
2014 Return `NULL' and set `bfd_error' on error; possible errors are:
2015 * `bfd_error_invalid_operation' - If output has already started for
2016 ABFD.
2018 * `bfd_error_no_memory' - If memory allocation fails.
2020 2.6.5.8 `bfd_make_section_with_flags'
2021 .....................................
2023 *Synopsis*
2024 asection *bfd_make_section_with_flags
2025 (bfd *, const char *name, flagword flags);
2026 *Description*
2027 Like `bfd_make_section_anyway', but return `NULL' (without calling
2028 bfd_set_error ()) without changing the section chain if there is
2029 already a section named NAME. Also set the attributes of the new
2030 section to the value FLAGS. If there is an error, return `NULL' and set
2031 `bfd_error'.
2033 2.6.5.9 `bfd_make_section'
2034 ..........................
2036 *Synopsis*
2037 asection *bfd_make_section (bfd *, const char *name);
2038 *Description*
2039 Like `bfd_make_section_anyway', but return `NULL' (without calling
2040 bfd_set_error ()) without changing the section chain if there is
2041 already a section named NAME. If there is an error, return `NULL' and
2042 set `bfd_error'.
2044 2.6.5.10 `bfd_set_section_flags'
2045 ................................
2047 *Synopsis*
2048 bfd_boolean bfd_set_section_flags
2049 (bfd *abfd, asection *sec, flagword flags);
2050 *Description*
2051 Set the attributes of the section SEC in the BFD ABFD to the value
2052 FLAGS. Return `TRUE' on success, `FALSE' on error. Possible error
2053 returns are:
2055 * `bfd_error_invalid_operation' - The section cannot have one or
2056 more of the attributes requested. For example, a .bss section in
2057 `a.out' may not have the `SEC_HAS_CONTENTS' field set.
2059 2.6.5.11 `bfd_map_over_sections'
2060 ................................
2062 *Synopsis*
2063 void bfd_map_over_sections
2064 (bfd *abfd,
2065 void (*func) (bfd *abfd, asection *sect, void *obj),
2066 void *obj);
2067 *Description*
2068 Call the provided function FUNC for each section attached to the BFD
2069 ABFD, passing OBJ as an argument. The function will be called as if by
2071 func (abfd, the_section, obj);
2073 This is the preferred method for iterating over sections; an
2074 alternative would be to use a loop:
2076 section *p;
2077 for (p = abfd->sections; p != NULL; p = p->next)
2078 func (abfd, p, ...)
2080 2.6.5.12 `bfd_sections_find_if'
2081 ...............................
2083 *Synopsis*
2084 asection *bfd_sections_find_if
2085 (bfd *abfd,
2086 bfd_boolean (*operation) (bfd *abfd, asection *sect, void *obj),
2087 void *obj);
2088 *Description*
2089 Call the provided function OPERATION for each section attached to the
2090 BFD ABFD, passing OBJ as an argument. The function will be called as if
2091 by
2093 operation (abfd, the_section, obj);
2095 It returns the first section for which OPERATION returns true.
2097 2.6.5.13 `bfd_set_section_size'
2098 ...............................
2100 *Synopsis*
2101 bfd_boolean bfd_set_section_size
2102 (bfd *abfd, asection *sec, bfd_size_type val);
2103 *Description*
2104 Set SEC to the size VAL. If the operation is ok, then `TRUE' is
2105 returned, else `FALSE'.
2107 Possible error returns:
2108 * `bfd_error_invalid_operation' - Writing has started to the BFD, so
2109 setting the size is invalid.
2111 2.6.5.14 `bfd_set_section_contents'
2112 ...................................
2114 *Synopsis*
2115 bfd_boolean bfd_set_section_contents
2116 (bfd *abfd, asection *section, const void *data,
2117 file_ptr offset, bfd_size_type count);
2118 *Description*
2119 Sets the contents of the section SECTION in BFD ABFD to the data
2120 starting in memory at DATA. The data is written to the output section
2121 starting at offset OFFSET for COUNT octets.
2123 Normally `TRUE' is returned, else `FALSE'. Possible error returns
2124 are:
2125 * `bfd_error_no_contents' - The output section does not have the
2126 `SEC_HAS_CONTENTS' attribute, so nothing can be written to it.
2128 * and some more too
2129 This routine is front end to the back end function
2130 `_bfd_set_section_contents'.
2132 2.6.5.15 `bfd_get_section_contents'
2133 ...................................
2135 *Synopsis*
2136 bfd_boolean bfd_get_section_contents
2137 (bfd *abfd, asection *section, void *location, file_ptr offset,
2138 bfd_size_type count);
2139 *Description*
2140 Read data from SECTION in BFD ABFD into memory starting at LOCATION.
2141 The data is read at an offset of OFFSET from the start of the input
2142 section, and is read for COUNT bytes.
2144 If the contents of a constructor with the `SEC_CONSTRUCTOR' flag set
2145 are requested or if the section does not have the `SEC_HAS_CONTENTS'
2146 flag set, then the LOCATION is filled with zeroes. If no errors occur,
2147 `TRUE' is returned, else `FALSE'.
2149 2.6.5.16 `bfd_malloc_and_get_section'
2150 .....................................
2152 *Synopsis*
2153 bfd_boolean bfd_malloc_and_get_section
2154 (bfd *abfd, asection *section, bfd_byte **buf);
2155 *Description*
2156 Read all data from SECTION in BFD ABFD into a buffer, *BUF, malloc'd by
2157 this function.
2159 2.6.5.17 `bfd_copy_private_section_data'
2160 ........................................
2162 *Synopsis*
2163 bfd_boolean bfd_copy_private_section_data
2164 (bfd *ibfd, asection *isec, bfd *obfd, asection *osec);
2165 *Description*
2166 Copy private section information from ISEC in the BFD IBFD to the
2167 section OSEC in the BFD OBFD. Return `TRUE' on success, `FALSE' on
2168 error. Possible error returns are:
2170 * `bfd_error_no_memory' - Not enough memory exists to create private
2171 data for OSEC.

2196 2.7 Symbols
2197 ===========
2199 BFD tries to maintain as much symbol information as it can when it
2200 moves information from file to file. BFD passes information to
2201 applications though the `asymbol' structure. When the application
2202 requests the symbol table, BFD reads the table in the native form and
2203 translates parts of it into the internal format. To maintain more than
2204 the information passed to applications, some targets keep some
2205 information "behind the scenes" in a structure only the particular back
2206 end knows about. For example, the coff back end keeps the original
2207 symbol table structure as well as the canonical structure when a BFD is
2208 read in. On output, the coff back end can reconstruct the output symbol
2209 table so that no information is lost, even information unique to coff
2210 which BFD doesn't know or understand. If a coff symbol table were read,
2211 but were written through an a.out back end, all the coff specific
2212 information would be lost. The symbol table of a BFD is not necessarily
2213 read in until a canonicalize request is made. Then the BFD back end
2214 fills in a table provided by the application with pointers to the
2215 canonical information. To output symbols, the application provides BFD
2216 with a table of pointers to pointers to `asymbol's. This allows
2217 applications like the linker to output a symbol as it was read, since
2218 the "behind the scenes" information will be still available.

2231 2.7.1 Reading symbols
2232 ---------------------
2234 There are two stages to reading a symbol table from a BFD: allocating
2235 storage, and the actual reading process. This is an excerpt from an
2236 application which reads the symbol table:
2238 long storage_needed;
2239 asymbol **symbol_table;
2240 long number_of_symbols;
2241 long i;
2243 storage_needed = bfd_get_symtab_upper_bound (abfd);
2245 if (storage_needed < 0)
2246 FAIL
2248 if (storage_needed == 0)
2249 return;
2251 symbol_table = xmalloc (storage_needed);
2252 ...
2253 number_of_symbols =
2254 bfd_canonicalize_symtab (abfd, symbol_table);
2256 if (number_of_symbols < 0)
2257 FAIL
2259 for (i = 0; i < number_of_symbols; i++)
2260 process_symbol (symbol_table[i]);
2262 All storage for the symbols themselves is in an objalloc connected
2263 to the BFD; it is freed when the BFD is closed.

2266 File: bfd.info, Node: Writing Symbols, Next: Mini Symbols, Prev: Reading Symbols, Up: Symbols
2268 2.7.2 Writing symbols
2269 ---------------------
2271 Writing of a symbol table is automatic when a BFD open for writing is
2272 closed. The application attaches a vector of pointers to pointers to
2273 symbols to the BFD being written, and fills in the symbol count. The
2274 close and cleanup code reads through the table provided and performs
2275 all the necessary operations. The BFD output code must always be
2276 provided with an "owned" symbol: one which has come from another BFD,
2277 or one which has been created using `bfd_make_empty_symbol'. Here is an
2278 example showing the creation of a symbol table with only one element:
2280 #include "bfd.h"
2281 int main (void)
2282 {
2283 bfd *abfd;
2284 asymbol *ptrs[2];
2285 asymbol *new;
2287 abfd = bfd_openw ("foo","a.out-sunos-big");
2288 bfd_set_format (abfd, bfd_object);
2289 new = bfd_make_empty_symbol (abfd);
2290 new->name = "dummy_symbol";
2291 new->section = bfd_make_section_old_way (abfd, ".text");
2292 new->flags = BSF_GLOBAL;
2293 new->value = 0x12345;
2295 ptrs[0] = new;
2296 ptrs[1] = 0;
2298 bfd_set_symtab (abfd, ptrs, 1);
2299 bfd_close (abfd);
2300 return 0;
2301 }
2303 ./makesym
2304 nm foo
2305 00012345 A dummy_symbol
2307 Many formats cannot represent arbitrary symbol information; for
2308 instance, the `a.out' object format does not allow an arbitrary number
2309 of sections. A symbol pointing to a section which is not one of
2310 `.text', `.data' or `.bss' cannot be described.

2315 2.7.3 Mini Symbols
2316 ------------------
2318 Mini symbols provide read-only access to the symbol table. They use
2319 less memory space, but require more time to access. They can be useful
2320 for tools like nm or objdump, which may have to handle symbol tables of
2321 extremely large executables.
2323 The `bfd_read_minisymbols' function will read the symbols into
2324 memory in an internal form. It will return a `void *' pointer to a
2325 block of memory, a symbol count, and the size of each symbol. The
2326 pointer is allocated using `malloc', and should be freed by the caller
2327 when it is no longer needed.
2329 The function `bfd_minisymbol_to_symbol' will take a pointer to a
2330 minisymbol, and a pointer to a structure returned by
2331 `bfd_make_empty_symbol', and return a `asymbol' structure. The return
2332 value may or may not be the same as the value from
2333 `bfd_make_empty_symbol' which was passed in.

2648 2.8 Archives
2649 ============
2651 *Description*
2652 An archive (or library) is just another BFD. It has a symbol table,
2653 although there's not much a user program will do with it.
2655 The big difference between an archive BFD and an ordinary BFD is
2656 that the archive doesn't have sections. Instead it has a chain of BFDs
2657 that are considered its contents. These BFDs can be manipulated like
2658 any other. The BFDs contained in an archive opened for reading will
2659 all be opened for reading. You may put either input or output BFDs
2660 into an archive opened for output; they will be handled correctly when
2661 the archive is closed.
2663 Use `bfd_openr_next_archived_file' to step through the contents of
2664 an archive opened for input. You don't have to read the entire archive
2665 if you don't want to! Read it until you find what you want.
2667 Archive contents of output BFDs are chained through the `next'
2668 pointer in a BFD. The first one is findable through the `archive_head'
2669 slot of the archive. Set it with `bfd_set_archive_head' (q.v.). A
2670 given BFD may be in only one open output archive at a time.
2672 As expected, the BFD archive code is more general than the archive
2673 code of any given environment. BFD archives may contain files of
2674 different formats (e.g., a.out and coff) and even different
2675 architectures. You may even place archives recursively into archives!
2677 This can cause unexpected confusion, since some archive formats are
2678 more expressive than others. For instance, Intel COFF archives can
2679 preserve long filenames; SunOS a.out archives cannot. If you move a
2680 file from the first to the second format and back again, the filename
2681 may be truncated. Likewise, different a.out environments have different
2682 conventions as to how they truncate filenames, whether they preserve
2683 directory names in filenames, etc. When interoperating with native
2684 tools, be sure your files are homogeneous.
2686 Beware: most of these formats do not react well to the presence of
2687 spaces in filenames. We do the best we can, but can't always handle
2688 this case due to restrictions in the format of archives. Many Unix
2689 utilities are braindead in regards to spaces and such in filenames
2690 anyway, so this shouldn't be much of a restriction.
2692 Archives are supported in BFD in `archive.c'.

2705 update SYM with the next symbol's information, returning that symbol's
2706 (internal) index into the symbol table.
2708 Supply `BFD_NO_MORE_SYMBOLS' as the PREVIOUS entry to get the first
2709 one; returns `BFD_NO_MORE_SYMBOLS' when you've already got the last one.
2711 A `carsym' is a canonical archive symbol. The only user-visible

2730 BFD on the first contained element and returns that. Subsequent calls
2731 should pass the archive and the previous return value to return a
2732 created BFD to the next contained element. NULL is returned when there
2733 are no more.

2738 2.9 File formats
2739 ================
2741 A format is a BFD concept of high level file contents type. The formats
2742 supported by BFD are:
2744 * `bfd_object'
2745 The BFD may contain data, symbols, relocations and debug info.
2747 * `bfd_archive'
2748 The BFD contains other BFDs and an optional index.
2750 * `bfd_core'
2751 The BFD contains the result of an executable core dump.
2753 2.9.1 File format functions
2754 ---------------------------
2756 2.9.1.1 `bfd_check_format'
2757 ..........................
2759 *Synopsis*
2760 bfd_boolean bfd_check_format (bfd *abfd, bfd_format format);
2761 *Description*
2762 Verify if the file attached to the BFD ABFD is compatible with the
2763 format FORMAT (i.e., one of `bfd_object', `bfd_archive' or `bfd_core').
2765 If the BFD has been set to a specific target before the call, only
2766 the named target and format combination is checked. If the target has
2767 not been set, or has been set to `default', then all the known target
2768 backends is interrogated to determine a match. If the default target
2769 matches, it is used. If not, exactly one target must recognize the
2770 file, or an error results.
2772 The function returns `TRUE' on success, otherwise `FALSE' with one
2773 of the following error codes:
2775 * `bfd_error_invalid_operation' - if `format' is not one of
2776 `bfd_object', `bfd_archive' or `bfd_core'.
2778 * `bfd_error_system_call' - if an error occured during a read - even
2779 some file mismatches can cause bfd_error_system_calls.
2781 * `file_not_recognised' - none of the backends recognised the file
2782 format.
2784 * `bfd_error_file_ambiguously_recognized' - more than one backend
2785 recognised the file format.
2787 2.9.1.2 `bfd_check_format_matches'
2788 ..................................
2790 *Synopsis*
2791 bfd_boolean bfd_check_format_matches
2792 (bfd *abfd, bfd_format format, char ***matching);
2793 *Description*
2794 Like `bfd_check_format', except when it returns FALSE with `bfd_errno'
2795 set to `bfd_error_file_ambiguously_recognized'. In that case, if
2796 MATCHING is not NULL, it will be filled in with a NULL-terminated list
2797 of the names of the formats that matched, allocated with `malloc'.
2798 Then the user may choose a format and try again.
2800 When done with the list that MATCHING points to, the caller should
2801 free it.
2803 2.9.1.3 `bfd_set_format'
2804 ........................
2806 *Synopsis*
2807 bfd_boolean bfd_set_format (bfd *abfd, bfd_format format);
2808 *Description*
2809 This function sets the file format of the BFD ABFD to the format
2810 FORMAT. If the target set in the BFD does not support the format
2811 requested, the format is invalid, or the BFD is not open for writing,
2812 then an error occurs.
2814 2.9.1.4 `bfd_format_string'
2815 ...........................
2817 *Synopsis*
2818 const char *bfd_format_string (bfd_format format);
2819 *Description*
2820 Return a pointer to a const string `invalid', `object', `archive',
2821 `core', or `unknown', depending upon the value of FORMAT.

2826 2.10 Relocations
2827 ================
2829 BFD maintains relocations in much the same way it maintains symbols:
2830 they are left alone until required, then read in en-masse and
2831 translated into an internal form. A common routine
2832 `bfd_perform_relocation' acts upon the canonical form to do the fixup.
2834 Relocations are maintained on a per section basis, while symbols are
2835 maintained on a per BFD basis.
2837 All that a back end has to do to fit the BFD interface is to create
2838 a `struct reloc_cache_entry' for each relocation in a particular
2839 section, and fill in the right bits of the structures.

2902 arelent;
2903 *Description*
2904 Here is a description of each of the fields within an `arelent':
2906 * `sym_ptr_ptr'
2907 The symbol table pointer points to a pointer to the symbol
2908 associated with the relocation request. It is the pointer into the
2909 table returned by the back end's `canonicalize_symtab' action. *Note
2910 Symbols::. The symbol is referenced through a pointer to a pointer so
2911 that tools like the linker can fix up all the symbols of the same name
2912 by modifying only one pointer. The relocation routine looks in the
2913 symbol and uses the base of the section the symbol is attached to and
2914 the value of the symbol as the initial relocation offset. If the symbol
2915 pointer is zero, then the section provided is looked up.
2917 * `address'
2918 The `address' field gives the offset in bytes from the base of the
2919 section data which owns the relocation record to the first byte of
2920 relocatable information. The actual data relocated will be relative to
2921 this point; for example, a relocation type which modifies the bottom
2922 two bytes of a four byte word would not touch the first byte pointed to
2923 in a big endian world.
2925 * `addend'
2926 The `addend' is a value provided by the back end to be added (!) to
2927 the relocation offset. Its interpretation is dependent upon the howto.
2928 For example, on the 68k the code:
2930 char foo[];
2931 main()
2932 {
2933 return foo[0x12345678];
2934 }
2936 Could be compiled into:
2938 linkw fp,#-4
2939 moveb @#12345678,d0
2940 extbl d0
2941 unlk fp
2942 rts
2944 This could create a reloc pointing to `foo', but leave the offset in
2945 the data, something like:
2947 RELOCATION RECORDS FOR [.text]:
2948 offset type value
2949 00000006 32 _foo
2951 00000000 4e56 fffc ; linkw fp,#-4
2952 00000004 1039 1234 5678 ; moveb @#12345678,d0
2953 0000000a 49c0 ; extbl d0
2954 0000000c 4e5e ; unlk fp
2955 0000000e 4e75 ; rts
2957 Using coff and an 88k, some instructions don't have enough space in
2958 them to represent the full address range, and pointers have to be
2959 loaded in two parts. So you'd get something like:
2961 or.u r13,r0,hi16(_foo+0x12345678)
2962 ld.b r2,r13,lo16(_foo+0x12345678)
2963 jmp r1
2965 This should create two relocs, both pointing to `_foo', and with
2966 0x12340000 in their addend field. The data would consist of:
2968 RELOCATION RECORDS FOR [.text]:
2969 offset type value
2970 00000002 HVRT16 _foo+0x12340000
2971 00000006 LVRT16 _foo+0x12340000
2973 00000000 5da05678 ; or.u r13,r0,0x5678
2974 00000004 1c4d5678 ; ld.b r2,r13,0x5678
2975 00000008 f400c001 ; jmp r1
2977 The relocation routine digs out the value from the data, adds it to
2978 the addend to get the original offset, and then adds the value of
2979 `_foo'. Note that all 32 bits have to be kept around somewhere, to cope
2980 with carry from bit 15 to bit 16.
2982 One further example is the sparc and the a.out format. The sparc has
2983 a similar problem to the 88k, in that some instructions don't have room
2984 for an entire offset, but on the sparc the parts are created in odd
2985 sized lumps. The designers of the a.out format chose to not use the
2986 data within the section for storing part of the offset; all the offset
2987 is kept within the reloc. Anything in the data should be ignored.
2989 save %sp,-112,%sp
2990 sethi %hi(_foo+0x12345678),%g2
2991 ldsb [%g2+%lo(_foo+0x12345678)],%i0
2992 ret
2993 restore
2995 Both relocs contain a pointer to `foo', and the offsets contain junk.
2997 RELOCATION RECORDS FOR [.text]:
2998 offset type value
2999 00000004 HI22 _foo+0x12345678
3000 00000008 LO10 _foo+0x12345678
3002 00000000 9de3bf90 ; save %sp,-112,%sp
3003 00000004 05000000 ; sethi %hi(_foo+0),%g2
3004 00000008 f048a000 ; ldsb [%g2+%lo(_foo+0)],%i0
3005 0000000c 81c7e008 ; ret
3006 00000010 81e80000 ; restore
3008 * `howto'
3009 The `howto' field can be imagined as a relocation instruction. It is
3010 a pointer to a structure which contains information on what to do with
3011 all of the other information in the reloc record and data section. A
3012 back end would normally have a relocation instruction set and turn
3013 relocations into pointers to the correct structure on input - but it
3014 would be possible to create each howto field on demand.
3016 2.10.1.1 `enum complain_overflow'

3020 a relocation.

3088 called rather than the normal function. This allows really
3089 strange relocation methods to be accommodated (e.g., i960 callj
3090 instructions). */
3091 bfd_reloc_status_type (*special_function)
3092 (bfd *, arelent *, struct bfd_symbol *, void *, asection *,
3093 bfd *, char **);
3095 /* The textual name of the relocation type. */
3096 char *name;
3098 /* Some formats record a relocation addend in the section contents
3099 rather than with the relocation. For ELF formats this is the
3100 distinction between USE_REL and USE_RELA (though the code checks
3101 for USE_REL == 1/0). The value of this field is TRUE if the
3102 addend is recorded with the section contents; when performing a
3103 partial link (ld -r) the section contents (the data) will be
3104 modified. The value of this field is FALSE if addends are
3105 recorded with the relocation (in arelent.addend); when performing
3106 a partial link the relocation will be modified.
3107 All relocations for all ELF USE_RELA targets should set this field
3108 to FALSE (values of TRUE should be looked on with suspicion).
3109 However, the converse is not true: not all relocations of all ELF
3110 USE_REL targets set this field to TRUE. Why this is so is peculiar
3111 to each particular target. For relocs that aren't used in partial
3112 links (e.g. GOT stuff) it doesn't matter what this is set to. */

3118 dst_mask to extract the addend from the section contents. If
3119 relocations do have an addend in the reloc, eg. ELF USE_RELA, this
3120 field should be zero. Non-zero values for ELF USE_RELA targets are

3133 Some formats leave the displacement part of an instruction
3134 empty (e.g., m88k bcs); this flag signals the fact. */

3185 2.10.1.5 `arelent_chain'

3208 Perform overflow checking on RELOCATION which has BITSIZE significant
3209 bits and will be shifted right by RIGHTSHIFT bits, on a machine with
3210 addresses containing ADDRSIZE significant bits. The result is either of

3213 2.10.1.7 `bfd_perform_relocation'
3214 .................................

3222 bfd *output_bfd,
3223 char **error_message);
3224 *Description*
3225 If OUTPUT_BFD is supplied to this function, the generated image will be
3226 relocatable; the relocations are copied to the output file after they
3227 have been changed to reflect the new state of the world. There are two
3228 ways of reflecting the results of partial linkage in an output file: by
3229 modifying the output data in place, and by modifying the relocation
3230 record. Some native formats (e.g., basic a.out and basic coff) have no
3231 way of specifying an addend in the relocation type, so the addend has
3232 to go in the output data. This is no big deal since in these formats
3233 the output data slot will always be big enough for the addend. Complex
3234 reloc types with addends were invented to solve just this problem. The
3235 ERROR_MESSAGE argument is set to an error message if this return
3236 `bfd_reloc_dangerous'.

3248 *Description*
3249 This looks remarkably like `bfd_perform_relocation', except it does not
3250 expect that the section contents have been filled in. I.e., it's
3251 suitable for use when creating, rather than applying a relocation.
3253 For now, this function should be considered reserved for the
3254 assembler.

3259 2.10.2 The howto manager
3260 ------------------------
3262 When an application wants to create a relocation, but doesn't know what
3263 the target machine might call it, it can find out by using this bit of
3264 code.
3266 2.10.2.1 `bfd_reloc_code_type'
3267 ..............................
3269 *Description*
3270 The insides of a reloc code. The idea is that, eventually, there will
3271 be one enumerator for every type of relocation we ever do. Pass one of
3272 these values to `bfd_reloc_type_lookup', and it'll return a howto
3273 pointer.
3275 This does mean that the application must determine the correct
3276 enumerator value; you can't get a howto pointer from a random set of
3277 attributes.
3279 Here are the possible values for `enum bfd_reloc_code_real':

3296 PC-relative relocations. Sometimes these are relative to the
3297 address of the relocation itself; sometimes they are relative to
3298 the start of the section containing the relocation. It depends on
3299 the specific target.

3364 These PC-relative relocations are stored as word displacements -
3365 i.e., byte displacements shifted right two bits. The 30-bit word
3366 displacement (<<32_PCREL_S2>> - 32 bits, shifted 2) is used on the
3367 SPARC. (SPARC tools generally refer to this as <<WDISP30>>.) The
3368 signed 16-bit displacement is used on the MIPS, and the 23-bit
3369 displacement is used on the Alpha.
3371 -- : BFD_RELOC_HI22
3372 -- : BFD_RELOC_LO10
3373 High 22 bits and low 10 bits of 32-bit value, placed into lower
3374 bits of the target word. These are used on the SPARC.
3376 -- : BFD_RELOC_GPREL16
3377 -- : BFD_RELOC_GPREL32
3378 For systems that allocate a Global Pointer register, these are
3379 displacements off that register. These relocation types are
3380 handled specially, because the value the register will have is
3381 decided relatively late.

3485 SPU Relocations.
3487 -- : BFD_RELOC_ALPHA_GPDISP_HI16
3488 Alpha ECOFF and ELF relocations. Some of these treat the symbol or
3489 "addend" in some special way. For GPDISP_HI16 ("gpdisp")
3490 relocations, the symbol is ignored when writing; when reading, it
3491 will be the absolute section symbol. The addend is the
3492 displacement in bytes of the "lda" instruction from the "ldah"
3493 instruction (which is at the address of this reloc).
3495 -- : BFD_RELOC_ALPHA_GPDISP_LO16
3496 For GPDISP_LO16 ("ignore") relocations, the symbol is handled as
3497 with GPDISP_HI16 relocs. The addend is ignored when writing the
3498 relocations out, and is filled in with the file's GP value on
3499 reading, for convenience.
3501 -- : BFD_RELOC_ALPHA_GPDISP
3502 The ELF GPDISP relocation is exactly the same as the GPDISP_HI16
3503 relocation except that there is no accompanying GPDISP_LO16
3504 relocation.
3506 -- : BFD_RELOC_ALPHA_LITERAL
3507 -- : BFD_RELOC_ALPHA_ELF_LITERAL
3508 -- : BFD_RELOC_ALPHA_LITUSE
3509 The Alpha LITERAL/LITUSE relocs are produced by a symbol reference;
3510 the assembler turns it into a LDQ instruction to load the address
3511 of the symbol, and then fills in a register in the real
3512 instruction.
3514 The LITERAL reloc, at the LDQ instruction, refers to the .lita
3515 section symbol. The addend is ignored when writing, but is filled
3516 in with the file's GP value on reading, for convenience, as with
3517 the GPDISP_LO16 reloc.
3519 The ELF_LITERAL reloc is somewhere between 16_GOTOFF and
3520 GPDISP_LO16. It should refer to the symbol to be referenced, as
3521 with 16_GOTOFF, but it generates output not based on the position
3522 within the .got section, but relative to the GP value chosen for
3523 the file during the final link stage.
3525 The LITUSE reloc, on the instruction using the loaded address,
3526 gives information to the linker that it might be able to use to
3527 optimize away some literal section references. The symbol is
3528 ignored (read as the absolute section symbol), and the "addend"
3529 indicates the type of instruction using the register: 1 - "memory"
3530 fmt insn 2 - byte-manipulation (byte offset reg) 3 - jsr (target
3531 of branch)
3533 -- : BFD_RELOC_ALPHA_HINT
3534 The HINT relocation indicates a value that should be filled into
3535 the "hint" field of a jmp/jsr/ret instruction, for possible branch-
3536 prediction logic which may be provided on some processors.
3538 -- : BFD_RELOC_ALPHA_LINKAGE
3539 The LINKAGE relocation outputs a linkage pair in the object file,
3540 which is filled by the linker.
3542 -- : BFD_RELOC_ALPHA_CODEADDR
3543 The CODEADDR relocation outputs a STO_CA in the object file, which
3544 is filled by the linker.
3546 -- : BFD_RELOC_ALPHA_GPREL_HI16
3547 -- : BFD_RELOC_ALPHA_GPREL_LO16
3548 The GPREL_HI/LO relocations together form a 32-bit offset from the
3549 GP register.
3551 -- : BFD_RELOC_ALPHA_BRSGP
3552 Like BFD_RELOC_23_PCREL_S2, except that the source and target must
3553 share a common GP, and the target address is adjusted for
3554 STO_ALPHA_STD_GPLOAD.
3556 -- : BFD_RELOC_ALPHA_NOP
3557 The NOP relocation outputs a NOP if the longword displacement
3558 between two procedure entry points is < 2^21.
3560 -- : BFD_RELOC_ALPHA_BSR
3561 The BSR relocation outputs a BSR if the longword displacement
3562 between two procedure entry points is < 2^21.
3564 -- : BFD_RELOC_ALPHA_LDA
3565 The LDA relocation outputs a LDA if the longword displacement
3566 between two procedure entry points is < 2^16.
3568 -- : BFD_RELOC_ALPHA_BOH
3569 The BOH relocation outputs a BSR if the longword displacement
3570 between two procedure entry points is < 2^21, or else a hint.

3938 -- : BFD_RELOC_I370_D12
3939 IBM 370/390 relocations
3941 -- : BFD_RELOC_CTOR
3942 The type of reloc used to build a constructor table - at the moment
3943 probably a 32 bit wide absolute relocation, but the target can
3944 choose. It generally does map to one of the other relocation
3945 types.
3947 -- : BFD_RELOC_ARM_PCREL_BRANCH
3948 ARM 26 bit pc-relative branch. The lowest two bits must be zero
3949 and are not stored in the instruction.
3951 -- : BFD_RELOC_ARM_PCREL_BLX
3952 ARM 26 bit pc-relative branch. The lowest bit must be zero and is
3953 not stored in the instruction. The 2nd lowest bit comes from a 1
3954 bit field in the instruction.
3956 -- : BFD_RELOC_THUMB_PCREL_BLX
3957 Thumb 22 bit pc-relative branch. The lowest bit must be zero and

4925 -- : BFD_RELOC_VTABLE_ENTRY
4926 These two relocations are used by the linker to determine which of
4927 the entries in a C++ virtual function table are actually used.
4928 When the -gc-sections option is given, the linker will zero out
4929 the entries that are not used, so that the code for those
4930 functions need not be included in the output.
4932 VTABLE_INHERIT is a zero-space relocation used to describe to the
4933 linker the inheritance tree of a C++ virtual function table. The
4934 relocation's symbol should be the parent class' vtable, and the
4935 relocation should be located at the child vtable.
4937 VTABLE_ENTRY is a zero-space relocation that describes the use of a
4938 virtual function table entry. The reloc's symbol should refer to
4939 the table of the class mentioned in the code. Off of that base,
4940 an offset describes the entry that is being used. For Rela hosts,
4941 this offset is stored in the reloc's addend. For Rel hosts, we
4942 are forced to put this offset in the reloc's section offset.

5629 2.12 Targets
5630 ============
5632 *Description*
5633 Each port of BFD to a different machine requires the creation of a
5634 target back end. All the back end provides to the root part of BFD is a
5635 structure containing pointers to functions which perform certain low
5636 level operations on files. BFD translates the applications's requests
5637 through a pointer into calls to the back end routines.
5639 When a file is opened with `bfd_openr', its format and target are
5640 unknown. BFD uses various mechanisms to determine how to interpret the
5641 file. The operations performed are:
5643 * Create a BFD by calling the internal routine `_bfd_new_bfd', then
5644 call `bfd_find_target' with the target string supplied to
5645 `bfd_openr' and the new BFD pointer.
5647 * If a null target string was provided to `bfd_find_target', look up
5648 the environment variable `GNUTARGET' and use that as the target
5649 string.
5651 * If the target string is still `NULL', or the target string is
5652 `default', then use the first item in the target vector as the
5653 target type, and set `target_defaulted' in the BFD to cause
5654 `bfd_check_format' to loop through all the targets. *Note
5655 bfd_target::. *Note Formats::.
5657 * Otherwise, inspect the elements in the target vector one by one,
5658 until a match on target name is found. When found, use it.
5660 * Otherwise return the error `bfd_error_invalid_target' to
5661 `bfd_openr'.
5663 * `bfd_openr' attempts to open the file using `bfd_open_file', and
5664 returns the BFD.
5665 Once the BFD has been opened and the target selected, the file
5666 format may be determined. This is done by calling `bfd_check_format' on
5667 the BFD with a suggested format. If `target_defaulted' has been set,
5668 each possible target type is tried to see if it recognizes the
5669 specified format. `bfd_check_format' returns `TRUE' when the caller
5670 guesses right.

5680 -----------------
5682 *Description*
5683 This structure contains everything that BFD knows about a target. It
5684 includes things like its byte order, name, and which routines to call
5685 to do various operations.
5687 Every BFD points to a target structure with its `xvec' member.
5689 The macros below are used to dispatch to functions through the
5690 `bfd_target' vector. They are used in a number of macros further down
5691 in `bfd.h', and are also used when calling various routines by hand
5692 inside the BFD implementation. The ARGLIST argument must be
5693 parenthesized; it contains all the arguments to the called function.
5695 They make the documentation (more) unpleasant to read, so if someone
5696 wants to fix this and not break the above, please do.
5697 #define BFD_SEND(bfd, message, arglist) \
5698 ((*((bfd)->xvec->message)) arglist)
5700 #ifdef DEBUG_BFD_SEND
5701 #undef BFD_SEND
5702 #define BFD_SEND(bfd, message, arglist) \
5703 (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
5704 ((*((bfd)->xvec->message)) arglist) : \
5705 (bfd_assert (__FILE__,__LINE__), NULL))
5706 #endif
5707 For operations which index on the BFD format:
5708 #define BFD_SEND_FMT(bfd, message, arglist) \
5709 (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist)
5711 #ifdef DEBUG_BFD_SEND
5712 #undef BFD_SEND_FMT
5713 #define BFD_SEND_FMT(bfd, message, arglist) \
5714 (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
5715 (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist) : \
5716 (bfd_assert (__FILE__,__LINE__), NULL))
5717 #endif
5718 This is the structure which defines the type of BFD this is. The
5719 `xvec' member of the struct `bfd' itself points here. Each module that
5720 implements access to a different target under BFD, defines one of these.
5722 FIXME, these names should be rationalised with the names of the
5723 entry points which call them. Too bad we can't have one macro to define
5724 them both!

6130 choose the first entry in the target list. Passing in the string
6131 "default" or setting the environment variable to "default" will cause
6132 the first entry in the target list to be returned, and
6133 "target_defaulted" will be set in the BFD if ABFD isn't `NULL'. This
6134 causes `bfd_check_format' to loop over all the targets to find the one
6135 that matches the file being read.

6141 const char ** bfd_target_list (void);
6142 *Description*
6143 Return a freshly malloced NULL-terminated vector of the names of all
6144 the valid BFD targets. Do not modify the names.

6150 const bfd_target *bfd_search_for_target
6151 (int (*search_func) (const bfd_target *, void *),
6152 void *);
6153 *Description*
6154 Return a pointer to the first transfer vector in the list of transfer
6155 vectors maintained by BFD that produces a non-zero result when passed
6156 to the function SEARCH_FUNC. The parameter DATA is passed, unexamined,
6157 to the search function.

6162 2.13 Architectures
6163 ==================
6165 BFD keeps one atom in a BFD describing the architecture of the data
6166 attached to the BFD: a pointer to a `bfd_arch_info_type'.
6168 Pointers to structures can be requested independently of a BFD so
6169 that an architecture's information can be interrogated without access
6170 to an open BFD.
6172 The architecture information is provided by each architecture
6173 package. The set of default architectures is selected by the macro
6174 `SELECT_ARCHITECTURES'. This is normally set up in the
6175 `config/TARGET.mt' file of your choice. If the name is not defined,
6176 then all the architectures supported are included.
6178 When BFD starts up, all the architectures are called with an
6179 initialize method. It is up to the architecture back end to insert as
6180 many items into the list of architectures as it wants to; generally
6181 this would be one for each machine and one for the default case (an
6182 item with a machine field of 0).
6184 BFD's idea of an architecture is implemented in `archures.c'.
6186 2.13.1 bfd_architecture
6187 -----------------------
6189 *Description*
6190 This enum gives the object file's CPU architecture, in a global
6191 sense--i.e., what processor family does it belong to? Another field
6192 indicates which processor within the family is in use. The machine
6193 gives a number which distinguishes different versions of the
6194 architecture, containing, for example, 2 and 3 for Intel i960 KA and
6195 i960 KB, and 68020 and 68030 for Motorola 68020 and 68030.

6760 2.14 Opening and closing BFDs
6761 =============================
6763 2.14.1 Functions for opening and closing
6764 ----------------------------------------
6766 2.14.1.1 `bfd_fopen'
6767 ....................
6769 *Synopsis*
6770 bfd *bfd_fopen (const char *filename, const char *target,
6771 const char *mode, int fd);
6772 *Description*
6773 Open the file FILENAME with the target TARGET. Return a pointer to the
6774 created BFD. If FD is not -1, then `fdopen' is used to open the file;
6775 otherwise, `fopen' is used. MODE is passed directly to `fopen' or
6776 `fdopen'.
6778 Calls `bfd_find_target', so TARGET is interpreted as by that
6779 function.
6781 The new BFD is marked as cacheable iff FD is -1.
6783 If `NULL' is returned then an error has occured. Possible errors
6784 are `bfd_error_no_memory', `bfd_error_invalid_target' or `system_call'
6785 error.
6787 2.14.1.2 `bfd_openr'
6788 ....................
6790 *Synopsis*
6791 bfd *bfd_openr (const char *filename, const char *target);
6792 *Description*
6793 Open the file FILENAME (using `fopen') with the target TARGET. Return
6794 a pointer to the created BFD.
6796 Calls `bfd_find_target', so TARGET is interpreted as by that
6797 function.
6799 If `NULL' is returned then an error has occured. Possible errors
6800 are `bfd_error_no_memory', `bfd_error_invalid_target' or `system_call'
6801 error.
6803 2.14.1.3 `bfd_fdopenr'
6804 ......................
6806 *Synopsis*
6807 bfd *bfd_fdopenr (const char *filename, const char *target, int fd);
6808 *Description*
6809 `bfd_fdopenr' is to `bfd_fopenr' much like `fdopen' is to `fopen'. It
6810 opens a BFD on a file already described by the FD supplied.
6812 When the file is later `bfd_close'd, the file descriptor will be
6813 closed. If the caller desires that this file descriptor be cached by
6814 BFD (opened as needed, closed as needed to free descriptors for other
6815 opens), with the supplied FD used as an initial file descriptor (but
6816 subject to closure at any time), call bfd_set_cacheable(bfd, 1) on the
6817 returned BFD. The default is to assume no caching; the file descriptor
6818 will remain open until `bfd_close', and will not be affected by BFD
6819 operations on other files.
6821 Possible errors are `bfd_error_no_memory',
6822 `bfd_error_invalid_target' and `bfd_error_system_call'.
6824 2.14.1.4 `bfd_openstreamr'
6825 ..........................
6827 *Synopsis*
6828 bfd *bfd_openstreamr (const char *, const char *, void *);
6829 *Description*
6830 Open a BFD for read access on an existing stdio stream. When the BFD
6831 is passed to `bfd_close', the stream will be closed.
6833 2.14.1.5 `bfd_openr_iovec'
6834 ..........................
6836 *Synopsis*
6837 bfd *bfd_openr_iovec (const char *filename, const char *target,
6838 void *(*open) (struct bfd *nbfd,
6839 void *open_closure),
6840 void *open_closure,
6841 file_ptr (*pread) (struct bfd *nbfd,
6842 void *stream,
6843 void *buf,
6844 file_ptr nbytes,
6845 file_ptr offset),
6846 int (*close) (struct bfd *nbfd,
6847 void *stream),
6848 int (*stat) (struct bfd *abfd,
6849 void *stream,
6850 struct stat *sb));
6851 *Description*
6852 Create and return a BFD backed by a read-only STREAM. The STREAM is
6853 created using OPEN, accessed using PREAD and destroyed using CLOSE.
6855 Calls `bfd_find_target', so TARGET is interpreted as by that
6856 function.
6858 Calls OPEN (which can call `bfd_zalloc' and `bfd_get_filename') to
6859 obtain the read-only stream backing the BFD. OPEN either succeeds
6860 returning the non-`NULL' STREAM, or fails returning `NULL' (setting
6861 `bfd_error').
6863 Calls PREAD to request NBYTES of data from STREAM starting at OFFSET
6864 (e.g., via a call to `bfd_read'). PREAD either succeeds returning the
6865 number of bytes read (which can be less than NBYTES when end-of-file),
6866 or fails returning -1 (setting `bfd_error').
6868 Calls CLOSE when the BFD is later closed using `bfd_close'. CLOSE
6869 either succeeds returning 0, or fails returning -1 (setting
6870 `bfd_error').
6872 Calls STAT to fill in a stat structure for bfd_stat, bfd_get_size,
6873 and bfd_get_mtime calls. STAT returns 0 on success, or returns -1 on
6874 failure (setting `bfd_error').
6876 If `bfd_openr_iovec' returns `NULL' then an error has occurred.
6877 Possible errors are `bfd_error_no_memory', `bfd_error_invalid_target'
6878 and `bfd_error_system_call'.
6880 2.14.1.6 `bfd_openw'
6881 ....................
6883 *Synopsis*
6884 bfd *bfd_openw (const char *filename, const char *target);
6885 *Description*
6886 Create a BFD, associated with file FILENAME, using the file format
6887 TARGET, and return a pointer to it.
6889 Possible errors are `bfd_error_system_call', `bfd_error_no_memory',
6890 `bfd_error_invalid_target'.
6892 2.14.1.7 `bfd_close'
6893 ....................
6895 *Synopsis*
6896 bfd_boolean bfd_close (bfd *abfd);
6897 *Description*
6898 Close a BFD. If the BFD was open for writing, then pending operations
6899 are completed and the file written out and closed. If the created file
6900 is executable, then `chmod' is called to mark it as such.
6902 All memory attached to the BFD is released.
6904 The file descriptor associated with the BFD is closed (even if it
6905 was passed in to BFD by `bfd_fdopenr').
6907 *Returns*
6908 `TRUE' is returned if all is ok, otherwise `FALSE'.
6910 2.14.1.8 `bfd_close_all_done'
6911 .............................
6913 *Synopsis*
6914 bfd_boolean bfd_close_all_done (bfd *);
6915 *Description*
6916 Close a BFD. Differs from `bfd_close' since it does not complete any
6917 pending operations. This routine would be used if the application had
6918 just used BFD for swapping and didn't want to use any of the writing
6919 code.
6921 If the created file is executable, then `chmod' is called to mark it
6922 as such.
6924 All memory attached to the BFD is released.
6926 *Returns*
6927 `TRUE' is returned if all is ok, otherwise `FALSE'.
6929 2.14.1.9 `bfd_create'
6930 .....................
6932 *Synopsis*
6933 bfd *bfd_create (const char *filename, bfd *templ);
6934 *Description*
6935 Create a new BFD in the manner of `bfd_openw', but without opening a
6936 file. The new BFD takes the target from the target used by TEMPLATE.
6937 The format is always set to `bfd_object'.
6939 2.14.1.10 `bfd_make_writable'
6940 .............................
6942 *Synopsis*
6943 bfd_boolean bfd_make_writable (bfd *abfd);
6944 *Description*
6945 Takes a BFD as created by `bfd_create' and converts it into one like as
6946 returned by `bfd_openw'. It does this by converting the BFD to
6947 BFD_IN_MEMORY. It's assumed that you will call `bfd_make_readable' on
6948 this bfd later.
6950 *Returns*
6951 `TRUE' is returned if all is ok, otherwise `FALSE'.
6953 2.14.1.11 `bfd_make_readable'
6954 .............................
6956 *Synopsis*
6957 bfd_boolean bfd_make_readable (bfd *abfd);
6958 *Description*
6959 Takes a BFD as created by `bfd_create' and `bfd_make_writable' and
6960 converts it into one like as returned by `bfd_openr'. It does this by
6961 writing the contents out to the memory buffer, then reversing the
6962 direction.
6964 *Returns*
6965 `TRUE' is returned if all is ok, otherwise `FALSE'.
6967 2.14.1.12 `bfd_alloc'
6968 .....................
6970 *Synopsis*

6986 ......................
6988 *Synopsis*
6989 void *bfd_zalloc (bfd *abfd, bfd_size_type wanted);
6990 *Description*
6991 Allocate a block of WANTED bytes of zeroed memory attached to `abfd'
6992 and return a pointer to it.

6995 .......................
6997 *Synopsis*
6998 void *bfd_zalloc2 (bfd *abfd, bfd_size_type nmemb, bfd_size_type size);
6999 *Description*
7000 Allocate a block of NMEMB elements of SIZE bytes each of zeroed memory

7039 *Synopsis*
7040 char *find_separate_debug_file (bfd *abfd);
7041 *Description*
7042 Searches ABFD for a reference to separate debugging information, scans
7043 various locations in the filesystem, including the file tree rooted at
7044 DEBUG_FILE_DIRECTORY, and returns a filename of such debugging
7045 information if the file is found and has matching CRC32. Returns NULL
7046 if no reference to debugging file exists, or file cannot be found.
7048 2.14.1.20 `bfd_follow_gnu_debuglink'
7049 ....................................
7051 *Synopsis*
7052 char *bfd_follow_gnu_debuglink (bfd *abfd, const char *dir);
7053 *Description*
7054 Takes a BFD and searches it for a .gnu_debuglink section. If this
7055 section is found, it examines the section for the name and checksum of
7056 a '.debug' file containing auxiliary debugging information. It then
7057 searches the filesystem for this .debug file in some standard
7058 locations, including the directory tree rooted at DIR, and if found
7059 returns the full filename.
7061 If DIR is NULL, it will search a default path configured into libbfd
7062 at build time. [XXX this feature is not currently implemented].
7064 *Returns*
7065 `NULL' on any errors or failure to locate the .debug file, otherwise a
7066 pointer to a heap-allocated string containing the filename. The caller
7067 is responsible for freeing this string.

7104 2.15.1 Internal functions
7105 -------------------------
7107 *Description*
7108 These routines are used within BFD. They are not intended for export,
7109 but are documented here for completeness.
7111 2.15.1.1 `bfd_write_bigendian_4byte_int'
7112 ........................................
7114 *Synopsis*
7115 bfd_boolean bfd_write_bigendian_4byte_int (bfd *, unsigned int);
7116 *Description*
7117 Write a 4 byte integer I to the output BFD ABFD, in big endian order
7118 regardless of what else is going on. This is useful in archives.
7120 2.15.1.2 `bfd_put_size'
7121 .......................
7123 2.15.1.3 `bfd_get_size'
7124 .......................
7126 *Description*
7127 These macros as used for reading and writing raw data in sections; each
7128 access (except for bytes) is vectored through the target format of the
7129 BFD and mangled accordingly. The mangling performs any necessary endian
7130 translations and removes alignment restrictions. Note that types
7131 accepted and returned by these macros are identical so they can be
7132 swapped around in macros--for example, `libaout.h' defines `GET_WORD'
7133 to either `bfd_get_32' or `bfd_get_64'.
7135 In the put routines, VAL must be a `bfd_vma'. If we are on a system
7136 without prototypes, the caller is responsible for making sure that is
7137 true, with a cast if necessary. We don't cast them in the macro
7138 definitions because that would prevent `lint' or `gcc -Wall' from
7139 detecting sins such as passing a pointer. To detect calling these with
7140 less than a `bfd_vma', use `gcc -Wconversion' on a host with 64 bit
7141 `bfd_vma''s.

7274 2.16 File caching
7275 =================
7277 The file caching mechanism is embedded within BFD and allows the
7278 application to open as many BFDs as it wants without regard to the
7279 underlying operating system's file descriptor limit (often as low as 20
7280 open files). The module in `cache.c' maintains a least recently used
7281 list of `BFD_CACHE_MAX_OPEN' files, and exports the name
7282 `bfd_cache_lookup', which runs around and makes sure that the required
7283 BFD is open. If not, then it chooses a file to close, closes it and
7284 opens the one wanted, returning its file handle.

7338 2.17 Linker Functions
7339 =====================
7341 The linker uses three special entry points in the BFD target vector.
7342 It is not necessary to write special routines for these entry points
7343 when creating a new BFD back end, since generic versions are provided.
7344 However, writing them can speed up linking and make it use
7345 significantly less runtime memory.
7347 The first routine creates a hash table used by the other routines.
7348 The second routine adds the symbols from an object file to the hash
7349 table. The third routine takes all the object files and links them
7350 together to create the output file. These routines are designed so
7351 that the linker proper does not need to know anything about the symbols
7352 in the object files that it is linking. The linker merely arranges the
7353 sections as directed by the linker script and lets BFD handle the
7354 details of symbols and relocs.
7356 The second routine and third routines are passed a pointer to a
7357 `struct bfd_link_info' structure (defined in `bfdlink.h') which holds
7358 information relevant to the link, including the linker hash table
7359 (which was created by the first routine) and a set of callback
7360 functions to the linker proper.
7362 The generic linker routines are in `linker.c', and use the header
7363 file `genlink.h'. As of this writing, the only back ends which have
7364 implemented versions of these routines are a.out (in `aoutx.h') and
7365 ECOFF (in `ecoff.c'). The a.out routines are used as examples
7366 throughout this section.

7377 2.17.1 Creating a linker hash table
7378 -----------------------------------
7380 The linker routines must create a hash table, which must be derived
7381 from `struct bfd_link_hash_table' described in `bfdlink.c'. *Note Hash
7382 Tables::, for information on how to create a derived hash table. This
7383 entry point is called using the target vector of the linker output file.
7385 The `_bfd_link_hash_table_create' entry point must allocate and
7386 initialize an instance of the desired hash table. If the back end does
7387 not require any additional information to be stored with the entries in
7388 the hash table, the entry point may simply create a `struct
7389 bfd_link_hash_table'. Most likely, however, some additional
7390 information will be needed.
7392 For example, with each entry in the hash table the a.out linker
7393 keeps the index the symbol has in the final output file (this index
7394 number is used so that when doing a relocatable link the symbol index
7395 used in the output file can be quickly filled in when copying over a
7396 reloc). The a.out linker code defines the required structures and
7397 functions for a hash table derived from `struct bfd_link_hash_table'.
7398 The a.out linker hash table is created by the function
7399 `NAME(aout,link_hash_table_create)'; it simply allocates space for the
7400 hash table, initializes it, and returns a pointer to it.
7402 When writing the linker routines for a new back end, you will
7403 generally not know exactly which fields will be required until you have
7404 finished. You should simply create a new hash table which defines no
7405 additional fields, and then simply add fields as they become necessary.

7410 2.17.2 Adding symbols to the hash table
7411 ---------------------------------------
7413 The linker proper will call the `_bfd_link_add_symbols' entry point for
7414 each object file or archive which is to be linked (typically these are
7415 the files named on the command line, but some may also come from the
7416 linker script). The entry point is responsible for examining the file.
7417 For an object file, BFD must add any relevant symbol information to
7418 the hash table. For an archive, BFD must determine which elements of
7419 the archive should be used and adding them to the link.
7421 The a.out version of this entry point is
7422 `NAME(aout,link_add_symbols)'.

7433 2.17.2.1 Differing file formats
7434 ...............................
7436 Normally all the files involved in a link will be of the same format,
7437 but it is also possible to link together different format object files,
7438 and the back end must support that. The `_bfd_link_add_symbols' entry
7439 point is called via the target vector of the file to be added. This
7440 has an important consequence: the function may not assume that the hash
7441 table is the type created by the corresponding
7442 `_bfd_link_hash_table_create' vector. All the `_bfd_link_add_symbols'
7443 function can assume about the hash table is that it is derived from
7444 `struct bfd_link_hash_table'.
7446 Sometimes the `_bfd_link_add_symbols' function must store some
7447 information in the hash table entry to be used by the `_bfd_final_link'
7448 function. In such a case the output bfd xvec must be checked to make
7449 sure that the hash table was created by an object file of the same
7450 format.
7452 The `_bfd_final_link' routine must be prepared to handle a hash
7453 entry without any extra information added by the
7454 `_bfd_link_add_symbols' function. A hash entry without extra
7455 information will also occur when the linker script directs the linker
7456 to create a symbol. Note that, regardless of how a hash table entry is
7457 added, all the fields will be initialized to some sort of null value by
7458 the hash table entry initialization function.
7460 See `ecoff_link_add_externals' for an example of how to check the
7461 output bfd before saving information (in this case, the ECOFF external
7462 symbol debugging information) in a hash table entry.

7467 2.17.2.2 Adding symbols from an object file
7468 ...........................................
7470 When the `_bfd_link_add_symbols' routine is passed an object file, it
7471 must add all externally visible symbols in that object file to the hash
7472 table. The actual work of adding the symbol to the hash table is
7473 normally handled by the function `_bfd_generic_link_add_one_symbol'.
7474 The `_bfd_link_add_symbols' routine is responsible for reading all the
7475 symbols from the object file and passing the correct information to
7476 `_bfd_generic_link_add_one_symbol'.
7478 The `_bfd_link_add_symbols' routine should not use
7479 `bfd_canonicalize_symtab' to read the symbols. The point of providing
7480 this routine is to avoid the overhead of converting the symbols into
7481 generic `asymbol' structures.
7483 `_bfd_generic_link_add_one_symbol' handles the details of combining
7484 common symbols, warning about multiple definitions, and so forth. It
7485 takes arguments which describe the symbol to add, notably symbol flags,
7486 a section, and an offset. The symbol flags include such things as
7487 `BSF_WEAK' or `BSF_INDIRECT'. The section is a section in the object
7488 file, or something like `bfd_und_section_ptr' for an undefined symbol
7489 or `bfd_com_section_ptr' for a common symbol.
7491 If the `_bfd_final_link' routine is also going to need to read the
7492 symbol information, the `_bfd_link_add_symbols' routine should save it
7493 somewhere attached to the object file BFD. However, the information
7494 should only be saved if the `keep_memory' field of the `info' argument
7495 is TRUE, so that the `-no-keep-memory' linker switch is effective.
7497 The a.out function which adds symbols from an object file is
7498 `aout_link_add_object_symbols', and most of the interesting work is in
7499 `aout_link_add_symbols'. The latter saves pointers to the hash tables
7500 entries created by `_bfd_generic_link_add_one_symbol' indexed by symbol
7501 number, so that the `_bfd_final_link' routine does not have to call the
7502 hash table lookup routine to locate the entry.

7507 2.17.2.3 Adding symbols from an archive
7508 .......................................
7510 When the `_bfd_link_add_symbols' routine is passed an archive, it must
7511 look through the symbols defined by the archive and decide which
7512 elements of the archive should be included in the link. For each such
7513 element it must call the `add_archive_element' linker callback, and it
7514 must add the symbols from the object file to the linker hash table.
7516 In most cases the work of looking through the symbols in the archive
7517 should be done by the `_bfd_generic_link_add_archive_symbols' function.
7518 This function builds a hash table from the archive symbol table and
7519 looks through the list of undefined symbols to see which elements
7520 should be included. `_bfd_generic_link_add_archive_symbols' is passed
7521 a function to call to make the final decision about adding an archive
7522 element to the link and to do the actual work of adding the symbols to
7523 the linker hash table.
7525 The function passed to `_bfd_generic_link_add_archive_symbols' must
7526 read the symbols of the archive element and decide whether the archive
7527 element should be included in the link. If the element is to be
7528 included, the `add_archive_element' linker callback routine must be
7529 called with the element as an argument, and the elements symbols must
7530 be added to the linker hash table just as though the element had itself
7531 been passed to the `_bfd_link_add_symbols' function.
7533 When the a.out `_bfd_link_add_symbols' function receives an archive,
7534 it calls `_bfd_generic_link_add_archive_symbols' passing
7535 `aout_link_check_archive_element' as the function argument.
7536 `aout_link_check_archive_element' calls `aout_link_check_ar_symbols'.
7537 If the latter decides to add the element (an element is only added if
7538 it provides a real, non-common, definition for a previously undefined
7539 or common symbol) it calls the `add_archive_element' callback and then
7540 `aout_link_check_archive_element' calls `aout_link_add_symbols' to
7541 actually add the symbols to the linker hash table.
7543 The ECOFF back end is unusual in that it does not normally call
7544 `_bfd_generic_link_add_archive_symbols', because ECOFF archives already
7545 contain a hash table of symbols. The ECOFF back end searches the

7551 2.17.3 Performing the final link
7552 --------------------------------
7554 When all the input files have been processed, the linker calls the
7555 `_bfd_final_link' entry point of the output BFD. This routine is
7556 responsible for producing the final output file, which has several
7557 aspects. It must relocate the contents of the input sections and copy
7558 the data into the output sections. It must build an output symbol
7559 table including any local symbols from the input files and the global
7560 symbols from the hash table. When producing relocatable output, it must
7561 modify the input relocs and write them into the output file. There may
7562 also be object format dependent work to be done.
7564 The linker will also call the `write_object_contents' entry point
7565 when the BFD is closed. The two entry points must work together in
7566 order to produce the correct output file.
7568 The details of how this works are inevitably dependent upon the
7569 specific object file format. The a.out `_bfd_final_link' routine is
7570 `NAME(aout,final_link)'.

7581 2.17.3.1 Information provided by the linker
7582 ...........................................
7584 Before the linker calls the `_bfd_final_link' entry point, it sets up
7585 some data structures for the function to use.
7587 The `input_bfds' field of the `bfd_link_info' structure will point
7588 to a list of all the input files included in the link. These files are
7589 linked through the `link_next' field of the `bfd' structure.
7591 Each section in the output file will have a list of `link_order'
7592 structures attached to the `map_head.link_order' field (the
7593 `link_order' structure is defined in `bfdlink.h'). These structures
7594 describe how to create the contents of the output section in terms of
7595 the contents of various input sections, fill constants, and,
7596 eventually, other types of information. They also describe relocs that
7597 must be created by the BFD backend, but do not correspond to any input
7598 file; this is used to support -Ur, which builds constructors while
7599 generating a relocatable object file.

7604 2.17.3.2 Relocating the section contents
7605 ........................................
7607 The `_bfd_final_link' function should look through the `link_order'
7608 structures attached to each section of the output file. Each
7609 `link_order' structure should either be handled specially, or it should
7610 be passed to the function `_bfd_default_link_order' which will do the
7611 right thing (`_bfd_default_link_order' is defined in `linker.c').
7613 For efficiency, a `link_order' of type `bfd_indirect_link_order'
7614 whose associated section belongs to a BFD of the same format as the
7615 output BFD must be handled specially. This type of `link_order'
7616 describes part of an output section in terms of a section belonging to
7617 one of the input files. The `_bfd_final_link' function should read the
7618 contents of the section and any associated relocs, apply the relocs to
7619 the section contents, and write out the modified section contents. If
7620 performing a relocatable link, the relocs themselves must also be
7621 modified and written out.
7623 The functions `_bfd_relocate_contents' and
7624 `_bfd_final_link_relocate' provide some general support for performing
7625 the actual relocations, notably overflow checking. Their arguments
7626 include information about the symbol the relocation is against and a
7627 `reloc_howto_type' argument which describes the relocation to perform.
7628 These functions are defined in `reloc.c'.
7630 The a.out function which handles reading, relocating, and writing
7631 section contents is `aout_link_input_section'. The actual relocation
7632 is done in `aout_link_input_section_std' and
7633 `aout_link_input_section_ext'.

7638 2.17.3.3 Writing the symbol table
7639 .................................
7641 The `_bfd_final_link' function must gather all the symbols in the input
7642 files and write them out. It must also write out all the symbols in
7643 the global hash table. This must be controlled by the `strip' and
7644 `discard' fields of the `bfd_link_info' structure.
7646 The local symbols of the input files will not have been entered into
7647 the linker hash table. The `_bfd_final_link' routine must consider
7648 each input file and include the symbols in the output file. It may be
7649 convenient to do this when looking through the `link_order' structures,
7650 or it may be done by stepping through the `input_bfds' list.
7652 The `_bfd_final_link' routine must also traverse the global hash
7653 table to gather all the externally visible symbols. It is possible
7654 that most of the externally visible symbols may be written out when
7655 considering the symbols of each input file, but it is still necessary
7656 to traverse the hash table since the linker script may have defined
7657 some symbols that are not in any of the input files.
7659 The `strip' field of the `bfd_link_info' structure controls which
7660 symbols are written out. The possible values are listed in
7661 `bfdlink.h'. If the value is `strip_some', then the `keep_hash' field
7662 of the `bfd_link_info' structure is a hash table of symbols to keep;
7663 each symbol should be looked up in this hash table, and only symbols
7664 which are present should be included in the output file.
7666 If the `strip' field of the `bfd_link_info' structure permits local
7667 symbols to be written out, the `discard' field is used to further
7668 controls which local symbols are included in the output file. If the
7669 value is `discard_l', then all local symbols which begin with a certain
7670 prefix are discarded; this is controlled by the
7671 `bfd_is_local_label_name' entry point.
7673 The a.out backend handles symbols by calling
7674 `aout_link_write_symbols' on each input BFD and then traversing the
7675 global hash table with the function `aout_link_write_other_symbol'. It
7676 builds a string table while writing out the symbols, which is written
7677 to the output file at the end of `NAME(aout,final_link)'.

7730 2.18 Hash Tables
7731 ================
7733 BFD provides a simple set of hash table functions. Routines are
7734 provided to initialize a hash table, to free a hash table, to look up a
7735 string in a hash table and optionally create an entry for it, and to
7736 traverse a hash table. There is currently no routine to delete an
7737 string from a hash table.
7739 The basic hash table does not permit any data to be stored with a
7740 string. However, a hash table is designed to present a base class from
7741 which other types of hash tables may be derived. These derived types
7742 may store additional information with the string. Hash tables were
7743 implemented in this way, rather than simply providing a data pointer in
7744 a hash table entry, because they were designed for use by the linker
7745 back ends. The linker may create thousands of hash table entries, and
7746 the overhead of allocating private data and storing and following
7747 pointers becomes noticeable.
7749 The basic hash table code is in `hash.c'.

7761 2.18.1 Creating and freeing a hash table
7762 ----------------------------------------
7764 To create a hash table, create an instance of a `struct bfd_hash_table'
7765 (defined in `bfd.h') and call `bfd_hash_table_init' (if you know
7766 approximately how many entries you will need, the function
7767 `bfd_hash_table_init_n', which takes a SIZE argument, may be used).
7768 `bfd_hash_table_init' returns `FALSE' if some sort of error occurs.
7770 The function `bfd_hash_table_init' take as an argument a function to
7771 use to create new entries. For a basic hash table, use the function
7772 `bfd_hash_newfunc'. *Note Deriving a New Hash Table Type::, for why
7773 you would want to use a different value for this argument.
7775 `bfd_hash_table_init' will create an objalloc which will be used to
7776 allocate new entries. You may allocate memory on this objalloc using
7777 `bfd_hash_allocate'.
7779 Use `bfd_hash_table_free' to free up all the memory that has been
7780 allocated for a hash table. This will not free up the `struct
7781 bfd_hash_table' itself, which you must provide.
7783 Use `bfd_hash_set_default_size' to set the default size of hash
7784 table to use.

7789 2.18.2 Looking up or entering a string
7790 --------------------------------------
7792 The function `bfd_hash_lookup' is used both to look up a string in the
7793 hash table and to create a new entry.
7795 If the CREATE argument is `FALSE', `bfd_hash_lookup' will look up a
7796 string. If the string is found, it will returns a pointer to a `struct
7797 bfd_hash_entry'. If the string is not found in the table
7798 `bfd_hash_lookup' will return `NULL'. You should not modify any of the
7799 fields in the returns `struct bfd_hash_entry'.
7801 If the CREATE argument is `TRUE', the string will be entered into
7802 the hash table if it is not already there. Either way a pointer to a
7803 `struct bfd_hash_entry' will be returned, either to the existing
7804 structure or to a newly created one. In this case, a `NULL' return
7805 means that an error occurred.
7807 If the CREATE argument is `TRUE', and a new entry is created, the
7808 COPY argument is used to decide whether to copy the string onto the
7809 hash table objalloc or not. If COPY is passed as `FALSE', you must be
7810 careful not to deallocate or modify the string as long as the hash table
7811 exists.

7816 2.18.3 Traversing a hash table
7817 ------------------------------
7819 The function `bfd_hash_traverse' may be used to traverse a hash table,
7820 calling a function on each element. The traversal is done in a random
7821 order.
7823 `bfd_hash_traverse' takes as arguments a function and a generic
7824 `void *' pointer. The function is called with a hash table entry (a
7825 `struct bfd_hash_entry *') and the generic pointer passed to
7826 `bfd_hash_traverse'. The function must return a `boolean' value, which
7827 indicates whether to continue traversing the hash table. If the
7828 function returns `FALSE', `bfd_hash_traverse' will stop the traversal
7829 and return immediately.

7834 2.18.4 Deriving a new hash table type
7835 -------------------------------------
7837 Many uses of hash tables want to store additional information which
7838 each entry in the hash table. Some also find it convenient to store
7839 additional information with the hash table itself. This may be done
7840 using a derived hash table.
7842 Since C is not an object oriented language, creating a derived hash
7843 table requires sticking together some boilerplate routines with a few
7844 differences specific to the type of hash table you want to create.
7846 An example of a derived hash table is the linker hash table. The
7847 structures for this are defined in `bfdlink.h'. The functions are in
7848 `linker.c'.
7850 You may also derive a hash table from an already derived hash table.
7851 For example, the a.out linker backend code uses a hash table derived
7852 from the linker hash table.

7863 2.18.4.1 Define the derived structures
7864 ......................................
7866 You must define a structure for an entry in the hash table, and a
7867 structure for the hash table itself.
7869 The first field in the structure for an entry in the hash table must
7870 be of the type used for an entry in the hash table you are deriving
7871 from. If you are deriving from a basic hash table this is `struct
7872 bfd_hash_entry', which is defined in `bfd.h'. The first field in the
7873 structure for the hash table itself must be of the type of the hash
7874 table you are deriving from itself. If you are deriving from a basic
7875 hash table, this is `struct bfd_hash_table'.
7877 For example, the linker hash table defines `struct
7878 bfd_link_hash_entry' (in `bfdlink.h'). The first field, `root', is of
7879 type `struct bfd_hash_entry'. Similarly, the first field in `struct
7880 bfd_link_hash_table', `table', is of type `struct bfd_hash_table'.

7885 2.18.4.2 Write the derived creation routine
7886 ...........................................
7888 You must write a routine which will create and initialize an entry in
7889 the hash table. This routine is passed as the function argument to
7890 `bfd_hash_table_init'.
7892 In order to permit other hash tables to be derived from the hash
7893 table you are creating, this routine must be written in a standard way.
7895 The first argument to the creation routine is a pointer to a hash
7896 table entry. This may be `NULL', in which case the routine should
7897 allocate the right amount of space. Otherwise the space has already
7898 been allocated by a hash table type derived from this one.
7900 After allocating space, the creation routine must call the creation
7901 routine of the hash table type it is derived from, passing in a pointer
7902 to the space it just allocated. This will initialize any fields used
7903 by the base hash table.
7905 Finally the creation routine must initialize any local fields for
7906 the new hash table type.
7908 Here is a boilerplate example of a creation routine. FUNCTION_NAME
7909 is the name of the routine. ENTRY_TYPE is the type of an entry in the
7910 hash table you are creating. BASE_NEWFUNC is the name of the creation
7911 routine of the hash table type your hash table is derived from.

7914 FUNCTION_NAME (struct bfd_hash_entry *entry,

7926 return NULL;
7927 }

7933 /* Initialize the local fields here. */
7935 return (struct bfd_hash_entry *) ret;
7936 }
7937 *Description*
7938 The creation routine for the linker hash table, which is in `linker.c',
7939 looks just like this example. FUNCTION_NAME is
7940 `_bfd_link_hash_newfunc'. ENTRY_TYPE is `struct bfd_link_hash_entry'.
7941 BASE_NEWFUNC is `bfd_hash_newfunc', the creation routine for a basic
7942 hash table.
7944 `_bfd_link_hash_newfunc' also initializes the local fields in a
7945 linker hash table entry: `type', `written' and `next'.

7950 2.18.4.3 Write other derived routines
7951 .....................................
7953 You will want to write other routines for your new hash table, as well.
7955 You will want an initialization routine which calls the
7956 initialization routine of the hash table you are deriving from and
7957 initializes any other local fields. For the linker hash table, this is
7958 `_bfd_link_hash_table_init' in `linker.c'.
7960 You will want a lookup routine which calls the lookup routine of the
7961 hash table you are deriving from and casts the result. The linker hash
7962 table uses `bfd_link_hash_lookup' in `linker.c' (this actually takes an
7963 additional argument which it uses to decide how to return the looked up
7964 value).
7966 You may want a traversal routine. This should just call the
7967 traversal routine of the hash table you are deriving from with
7968 appropriate casts. The linker hash table uses `bfd_link_hash_traverse'
7969 in `linker.c'.
7971 These routines may simply be defined as macros. For example, the
7972 a.out backend linker hash table, which is derived from the linker hash
7973 table, uses macros for the lookup and traversal routines. These are
7974 `aout_link_hash_lookup' and `aout_link_hash_traverse' in aoutx.h.

8001 3.2 a.out backends
8002 ==================
8004 *Description*
8005 BFD supports a number of different flavours of a.out format, though the
8006 major differences are only the sizes of the structures on disk, and the
8007 shape of the relocation information.
8009 The support is split into a basic support file `aoutx.h' and other
8010 files which derive functions from the base. One derivation file is
8011 `aoutf1.h' (for a.out flavour 1), and adds to the basic a.out functions
8012 support for sun3, sun4, 386 and 29k a.out files, to create a target
8013 jump vector for a specific target.
8015 This information is further split out into more specific files for
8016 each machine, including `sunos.c' for sun3 and sun4, `newsos3.c' for
8017 the Sony NEWS, and `demo64.c' for a demonstration of a 64 bit a.out
8018 format.
8020 The base file `aoutx.h' defines general mechanisms for reading and
8021 writing records to and from disk and various other methods which BFD
8022 requires. It is included by `aout32.c' and `aout64.c' to form the names
8023 `aout_32_swap_exec_header_in', `aout_64_swap_exec_header_in', etc.
8025 As an example, this is what goes on to make the back end for a sun4,
8026 from `aout32.c':
8028 #define ARCH_SIZE 32
8029 #include "aoutx.h"
8031 Which exports names:
8033 ...
8034 aout_32_canonicalize_reloc
8035 aout_32_find_nearest_line
8036 aout_32_get_lineno
8037 aout_32_get_reloc_upper_bound
8038 ...
8040 from `sunos.c':
8042 #define TARGET_NAME "a.out-sunos-big"
8043 #define VECNAME sunos_big_vec
8044 #include "aoutf1.h"
8046 requires all the names from `aout32.c', and produces the jump vector
8048 sunos_big_vec
8050 The file `host-aout.c' is a special case. It is for a large set of
8051 hosts that use "more or less standard" a.out files, and for which
8052 cross-debugging is not interesting. It uses the standard 32-bit a.out
8053 support routines, but determines the file offsets and addresses of the
8054 text, data, and BSS sections, the machine architecture and machine
8055 type, and the entry point address, in a host-dependent manner. Once
8056 these values have been determined, generic code is used to handle the
8057 object file.
8059 When porting it to run on a new system, you must supply:
8061 HOST_PAGE_SIZE
8062 HOST_SEGMENT_SIZE
8063 HOST_MACHINE_ARCH (optional)
8064 HOST_MACHINE_MACHINE (optional)
8065 HOST_TEXT_START_ADDR
8066 HOST_STACK_END_ADDR
8068 in the file `../include/sys/h-XXX.h' (for your host). These values,
8069 plus the structures and macros defined in `a.out.h' on your host
8070 system, will produce a BFD target that will access ordinary a.out files
8071 on your host. To configure a new machine to use `host-aout.c', specify:

8080 3.2.1 Relocations
8081 -----------------
8083 *Description*
8084 The file `aoutx.h' provides for both the _standard_ and _extended_
8085 forms of a.out relocation records.
8087 The standard records contain only an address, a symbol index, and a
8088 type field. The extended records (used on 29ks and sparcs) also have a
8089 full integer for an addend.
8091 3.2.2 Internal entry points
8092 ---------------------------
8094 *Description*
8095 `aoutx.h' exports several routines for accessing the contents of an
8096 a.out file, which are gathered and exported in turn by various format
8097 specific files (eg sunos.c).

8188 3.3 coff backends
8189 =================
8191 BFD supports a number of different flavours of coff format. The major
8192 differences between formats are the sizes and alignments of fields in
8193 structures on disk, and the occasional extra field.
8195 Coff in all its varieties is implemented with a few common files and
8196 a number of implementation specific files. For example, The 88k bcs
8197 coff format is implemented in the file `coff-m88k.c'. This file
8198 `#include's `coff/m88k.h' which defines the external structure of the
8199 coff format for the 88k, and `coff/internal.h' which defines the
8200 internal structure. `coff-m88k.c' also defines the relocations used by
8201 the 88k format *Note Relocations::.
8203 The Intel i960 processor version of coff is implemented in
8204 `coff-i960.c'. This file has the same structure as `coff-m88k.c',
8205 except that it includes `coff/i960.h' rather than `coff-m88k.h'.
8207 3.3.1 Porting to a new version of coff
8208 --------------------------------------
8210 The recommended method is to select from the existing implementations
8211 the version of coff which is most like the one you want to use. For
8212 example, we'll say that i386 coff is the one you select, and that your
8213 coff flavour is called foo. Copy `i386coff.c' to `foocoff.c', copy
8214 `../include/coff/i386.h' to `../include/coff/foo.h', and add the lines
8215 to `targets.c' and `Makefile.in' so that your new back end is used.
8216 Alter the shapes of the structures in `../include/coff/foo.h' so that
8217 they match what you need. You will probably also have to add `#ifdef's
8218 to the code in `coff/internal.h' and `coffcode.h' if your version of
8219 coff is too wild.
8221 You can verify that your new BFD backend works quite simply by
8222 building `objdump' from the `binutils' directory, and making sure that
8223 its version of what's going on and your host system's idea (assuming it
8224 has the pretty standard coff dump utility, usually called `att-dump' or
8225 just `dump') are the same. Then clean up your code, and send what
8226 you've done to Cygnus. Then your stuff will be in the next release, and
8227 you won't have to keep integrating it.
8229 3.3.2 How the coff backend works
8230 --------------------------------
8232 3.3.2.1 File layout
8233 ...................
8235 The Coff backend is split into generic routines that are applicable to
8236 any Coff target and routines that are specific to a particular target.
8237 The target-specific routines are further split into ones which are
8238 basically the same for all Coff targets except that they use the
8239 external symbol format or use different values for certain constants.
8241 The generic routines are in `coffgen.c'. These routines work for
8242 any Coff target. They use some hooks into the target specific code;
8243 the hooks are in a `bfd_coff_backend_data' structure, one of which
8244 exists for each target.
8246 The essentially similar target-specific routines are in
8247 `coffcode.h'. This header file includes executable C code. The
8248 various Coff targets first include the appropriate Coff header file,
8249 make any special defines that are needed, and then include `coffcode.h'.
8251 Some of the Coff targets then also have additional routines in the
8252 target source file itself.
8254 For example, `coff-i960.c' includes `coff/internal.h' and
8255 `coff/i960.h'. It then defines a few constants, such as `I960', and
8256 includes `coffcode.h'. Since the i960 has complex relocation types,
8257 `coff-i960.c' also includes some code to manipulate the i960 relocs.
8258 This code is not in `coffcode.h' because it would not be used by any
8259 other target.
8261 3.3.2.2 Coff long section names
8262 ...............................
8264 In the standard Coff object format, section names are limited to the
8265 eight bytes available in the `s_name' field of the `SCNHDR' section
8266 header structure. The format requires the field to be NUL-padded, but
8267 not necessarily NUL-terminated, so the longest section names permitted
8268 are a full eight characters.
8270 The Microsoft PE variants of the Coff object file format add an
8271 extension to support the use of long section names. This extension is
8272 defined in section 4 of the Microsoft PE/COFF specification (rev 8.1).
8273 If a section name is too long to fit into the section header's `s_name'
8274 field, it is instead placed into the string table, and the `s_name'
8275 field is filled with a slash ("/") followed by the ASCII decimal
8276 representation of the offset of the full name relative to the string
8277 table base.
8279 Note that this implies that the extension can only be used in object
8280 files, as executables do not contain a string table. The standard
8281 specifies that long section names from objects emitted into executable
8282 images are to be truncated.
8284 However, as a GNU extension, BFD can generate executable images that
8285 contain a string table and long section names. This would appear to be
8286 technically valid, as the standard only says that Coff debugging
8287 information is deprecated, not forbidden, and in practice it works,
8288 although some tools that parse PE files expecting the MS standard
8289 format may become confused; `PEview' is one known example.
8291 The functionality is supported in BFD by code implemented under the
8292 control of the macro `COFF_LONG_SECTION_NAMES'. If not defined, the
8293 format does not support long section names in any way. If defined, it
8294 is used to initialise a flag, `_bfd_coff_long_section_names', and a
8295 hook function pointer, `_bfd_coff_set_long_section_names', in the Coff
8296 backend data structure. The flag controls the generation of long
8297 section names in output BFDs at runtime; if it is false, as it will be
8298 by default when generating an executable image, long section names are
8299 truncated; if true, the long section names extension is employed. The
8300 hook points to a function that allows the value of the flag to be
8301 altered at runtime, on formats that support long section names at all;
8302 on other formats it points to a stub that returns an error indication.
8303 With input BFDs, the flag is set according to whether any long section
8304 names are detected while reading the section headers. For a completely
8305 new BFD, the flag is set to the default for the target format. This
8306 information can be used by a client of the BFD library when deciding
8307 what output format to generate, and means that a BFD that is opened for
8308 read and subsequently converted to a writeable BFD and modified
8309 in-place will retain whatever format it had on input.
8311 If `COFF_LONG_SECTION_NAMES' is simply defined (blank), or is
8312 defined to the value "1", then long section names are enabled by
8313 default; if it is defined to the value zero, they are disabled by
8314 default (but still accepted in input BFDs). The header `coffcode.h'
8315 defines a macro, `COFF_DEFAULT_LONG_SECTION_NAMES', which is used in
8316 the backends to initialise the backend data structure fields
8317 appropriately; see the comments for further detail.
8319 3.3.2.3 Bit twiddling
8320 .....................
8322 Each flavour of coff supported in BFD has its own header file
8323 describing the external layout of the structures. There is also an
8324 internal description of the coff layout, in `coff/internal.h'. A major
8325 function of the coff backend is swapping the bytes and twiddling the
8326 bits to translate the external form of the structures into the normal
8327 internal form. This is all performed in the `bfd_swap'_thing_direction
8328 routines. Some elements are different sizes between different versions
8329 of coff; it is the duty of the coff version specific include file to
8330 override the definitions of various packing routines in `coffcode.h'.
8331 E.g., the size of line number entry in coff is sometimes 16 bits, and
8332 sometimes 32 bits. `#define'ing `PUT_LNSZ_LNNO' and `GET_LNSZ_LNNO'
8333 will select the correct one. No doubt, some day someone will find a
8334 version of coff which has a varying field size not catered to at the
8335 moment. To port BFD, that person will have to add more `#defines'.
8336 Three of the bit twiddling routines are exported to `gdb';
8337 `coff_swap_aux_in', `coff_swap_sym_in' and `coff_swap_lineno_in'. `GDB'
8338 reads the symbol table on its own, but uses BFD to fix things up. More
8339 of the bit twiddlers are exported for `gas'; `coff_swap_aux_out',
8340 `coff_swap_sym_out', `coff_swap_lineno_out', `coff_swap_reloc_out',
8341 `coff_swap_filehdr_out', `coff_swap_aouthdr_out',
8342 `coff_swap_scnhdr_out'. `Gas' currently keeps track of all the symbol
8343 table and reloc drudgery itself, thereby saving the internal BFD
8344 overhead, but uses BFD to swap things on the way out, making cross
8345 ports much safer. Doing so also allows BFD (and thus the linker) to
8346 use the same header files as `gas', which makes one avenue to disaster
8347 disappear.
8349 3.3.2.4 Symbol reading
8350 ......................
8352 The simple canonical form for symbols used by BFD is not rich enough to
8353 keep all the information available in a coff symbol table. The back end
8354 gets around this problem by keeping the original symbol table around,
8355 "behind the scenes".
8357 When a symbol table is requested (through a call to
8358 `bfd_canonicalize_symtab'), a request gets through to
8359 `coff_get_normalized_symtab'. This reads the symbol table from the coff
8360 file and swaps all the structures inside into the internal form. It
8361 also fixes up all the pointers in the table (represented in the file by
8362 offsets from the first symbol in the table) into physical pointers to
8363 elements in the new internal table. This involves some work since the
8364 meanings of fields change depending upon context: a field that is a
8365 pointer to another structure in the symbol table at one moment may be
8366 the size in bytes of a structure at the next. Another pass is made
8367 over the table. All symbols which mark file names (`C_FILE' symbols)
8368 are modified so that the internal string points to the value in the
8369 auxent (the real filename) rather than the normal text associated with
8370 the symbol (`".file"').
8372 At this time the symbol names are moved around. Coff stores all
8373 symbols less than nine characters long physically within the symbol
8374 table; longer strings are kept at the end of the file in the string
8375 table. This pass moves all strings into memory and replaces them with
8376 pointers to the strings.
8378 The symbol table is massaged once again, this time to create the
8379 canonical table used by the BFD application. Each symbol is inspected
8380 in turn, and a decision made (using the `sclass' field) about the
8381 various flags to set in the `asymbol'. *Note Symbols::. The generated
8382 canonical table shares strings with the hidden internal symbol table.
8384 Any linenumbers are read from the coff file too, and attached to the
8385 symbols which own the functions the linenumbers belong to.
8387 3.3.2.5 Symbol writing
8388 ......................
8390 Writing a symbol to a coff file which didn't come from a coff file will
8391 lose any debugging information. The `asymbol' structure remembers the
8392 BFD from which the symbol was taken, and on output the back end makes
8393 sure that the same destination target as source target is present.
8395 When the symbols have come from a coff file then all the debugging
8396 information is preserved.
8398 Symbol tables are provided for writing to the back end in a vector
8399 of pointers to pointers. This allows applications like the linker to
8400 accumulate and output large symbol tables without having to do too much
8401 byte copying.
8403 This function runs through the provided symbol table and patches
8404 each symbol marked as a file place holder (`C_FILE') to point to the
8405 next file place holder in the list. It also marks each `offset' field
8406 in the list with the offset from the first symbol of the current symbol.
8408 Another function of this procedure is to turn the canonical value
8409 form of BFD into the form used by coff. Internally, BFD expects symbol
8410 values to be offsets from a section base; so a symbol physically at
8411 0x120, but in a section starting at 0x100, would have the value 0x20.
8412 Coff expects symbols to contain their final value, so symbols have
8413 their values changed at this point to reflect their sum with their
8414 owning section. This transformation uses the `output_section' field of
8415 the `asymbol''s `asection' *Note Sections::.
8417 * `coff_mangle_symbols'
8418 This routine runs though the provided symbol table and uses the
8419 offsets generated by the previous pass and the pointers generated when
8420 the symbol table was read in to create the structured hierarchy
8421 required by coff. It changes each pointer to a symbol into the index
8422 into the symbol table of the asymbol.
8424 * `coff_write_symbols'
8425 This routine runs through the symbol table and patches up the
8426 symbols from their internal form into the coff way, calls the bit
8427 twiddlers, and writes out the table to the file.
8429 3.3.2.6 `coff_symbol_type'

8788 3.3.2.8 Writing relocations
8789 ...........................
8791 To write relocations, the back end steps though the canonical
8792 relocation table and create an `internal_reloc'. The symbol index to
8793 use is removed from the `offset' field in the symbol table supplied.
8794 The address comes directly from the sum of the section base address and
8795 the relocation offset; the type is dug directly from the howto field.
8796 Then the `internal_reloc' is swapped into the shape of an
8797 `external_reloc' and written out to disk.
8799 3.3.2.9 Reading linenumbers
8800 ...........................
8802 Creating the linenumber table is done by reading in the entire coff
8803 linenumber table, and creating another table for internal use.
8805 A coff linenumber table is structured so that each function is
8806 marked as having a line number of 0. Each line within the function is
8807 an offset from the first line in the function. The base of the line
8808 number information for the table is stored in the symbol associated
8809 with the function.
8811 Note: The PE format uses line number 0 for a flag indicating a new
8812 source file.
8814 The information is copied from the external to the internal table,
8815 and each symbol which marks a function is marked by pointing its...
8817 How does this work ?
8819 3.3.2.10 Reading relocations
8820 ............................
8822 Coff relocations are easily transformed into the internal BFD form
8823 (`arelent').
8825 Reading a coff relocation table is done in the following stages:
8827 * Read the entire coff relocation table into memory.
8829 * Process each relocation in turn; first swap it from the external
8830 to the internal form.
8832 * Turn the symbol referenced in the relocation's symbol index into a
8833 pointer into the canonical symbol table. This table is the same
8834 as the one returned by a call to `bfd_canonicalize_symtab'. The
8835 back end will call that routine and save the result if a
8836 canonicalization hasn't been done.
8838 * The reloc index is turned into a pointer to a howto structure, in
8839 a back end specific way. For instance, the 386 and 960 use the
8840 `r_type' to directly produce an index into a howto table vector;
8841 the 88k subtracts a number from the `r_type' field and creates an
8842 addend field.

8847 3.4 ELF backends
8848 ================
8850 BFD support for ELF formats is being worked on. Currently, the best
8851 supported back ends are for sparc and i386 (running svr4 or Solaris 2).
8853 Documentation of the internals of the support code still needs to be
8854 written. The code is changing quickly enough that we haven't bothered
8855 yet.

8860 3.5 mmo backend
8861 ===============
8863 The mmo object format is used exclusively together with Professor
8864 Donald E. Knuth's educational 64-bit processor MMIX. The simulator
8865 `mmix' which is available at
8866 `http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz'
8867 understands this format. That package also includes a combined
8868 assembler and linker called `mmixal'. The mmo format has no advantages
8869 feature-wise compared to e.g. ELF. It is a simple non-relocatable
8870 object format with no support for archives or debugging information,
8871 except for symbol value information and line numbers (which is not yet
8872 implemented in BFD). See
8873 `http://www-cs-faculty.stanford.edu/~knuth/mmix.html' for more
8874 information about MMIX. The ELF format is used for intermediate object
8875 files in the BFD implementation.

8886 3.5.1 File layout
8887 -----------------
8889 The mmo file contents is not partitioned into named sections as with
8890 e.g. ELF. Memory areas is formed by specifying the location of the
8891 data that follows. Only the memory area `0x0000...00' to `0x01ff...ff'
8892 is executable, so it is used for code (and constants) and the area
8893 `0x2000...00' to `0x20ff...ff' is used for writable data. *Note mmo
8894 section mapping::.
8896 There is provision for specifying "special data" of 65536 different
8897 types. We use type 80 (decimal), arbitrarily chosen the same as the
8898 ELF `e_machine' number for MMIX, filling it with section information
8899 normally found in ELF objects. *Note mmo section mapping::.
8901 Contents is entered as 32-bit words, xor:ed over previous contents,
8902 always zero-initialized. A word that starts with the byte `0x98' forms
8903 a command called a `lopcode', where the next byte distinguished between
8904 the thirteen lopcodes. The two remaining bytes, called the `Y' and `Z'
8905 fields, or the `YZ' field (a 16-bit big-endian number), are used for
8906 various purposes different for each lopcode. As documented in
8907 `http://www-cs-faculty.stanford.edu/~knuth/mmixal-intro.ps.gz', the
8908 lopcodes are:
8910 `lop_quote'
8911 0x98000001. The next word is contents, regardless of whether it
8912 starts with 0x98 or not.
8914 `lop_loc'
8915 0x9801YYZZ, where `Z' is 1 or 2. This is a location directive,
8916 setting the location for the next data to the next 32-bit word
8917 (for Z = 1) or 64-bit word (for Z = 2), plus Y * 2^56. Normally
8918 `Y' is 0 for the text segment and 2 for the data segment.
8920 `lop_skip'
8921 0x9802YYZZ. Increase the current location by `YZ' bytes.
8923 `lop_fixo'
8924 0x9803YYZZ, where `Z' is 1 or 2. Store the current location as 64
8925 bits into the location pointed to by the next 32-bit (Z = 1) or
8926 64-bit (Z = 2) word, plus Y * 2^56.
8928 `lop_fixr'
8929 0x9804YYZZ. `YZ' is stored into the current location plus 2 - 4 *
8930 YZ.
8932 `lop_fixrx'
8933 0x980500ZZ. `Z' is 16 or 24. A value `L' derived from the
8934 following 32-bit word are used in a manner similar to `YZ' in
8935 lop_fixr: it is xor:ed into the current location minus 4 * L. The
8936 first byte of the word is 0 or 1. If it is 1, then L = (LOWEST 24
8937 BITS OF WORD) - 2^Z, if 0, then L = (LOWEST 24 BITS OF WORD).
8939 `lop_file'
8940 0x9806YYZZ. `Y' is the file number, `Z' is count of 32-bit words.
8941 Set the file number to `Y' and the line counter to 0. The next Z
8942 * 4 bytes contain the file name, padded with zeros if the count is
8943 not a multiple of four. The same `Y' may occur multiple times,
8944 but `Z' must be 0 for all but the first occurrence.
8946 `lop_line'
8947 0x9807YYZZ. `YZ' is the line number. Together with lop_file, it
8948 forms the source location for the next 32-bit word. Note that for
8949 each non-lopcode 32-bit word, line numbers are assumed incremented
8950 by one.
8952 `lop_spec'
8953 0x9808YYZZ. `YZ' is the type number. Data until the next lopcode
8954 other than lop_quote forms special data of type `YZ'. *Note mmo
8955 section mapping::.
8957 Other types than 80, (or type 80 with a content that does not
8958 parse) is stored in sections named `.MMIX.spec_data.N' where N is
8959 the `YZ'-type. The flags for such a sections say not to allocate
8960 or load the data. The vma is 0. Contents of multiple occurrences
8961 of special data N is concatenated to the data of the previous
8962 lop_spec Ns. The location in data or code at which the lop_spec
8963 occurred is lost.
8965 `lop_pre'
8966 0x980901ZZ. The first lopcode in a file. The `Z' field forms the
8967 length of header information in 32-bit words, where the first word
8968 tells the time in seconds since `00:00:00 GMT Jan 1 1970'.
8970 `lop_post'
8971 0x980a00ZZ. Z > 32. This lopcode follows after all
8972 content-generating lopcodes in a program. The `Z' field denotes
8973 the value of `rG' at the beginning of the program. The following
8974 256 - Z big-endian 64-bit words are loaded into global registers
8975 `$G' ... `$255'.
8977 `lop_stab'
8978 0x980b0000. The next-to-last lopcode in a program. Must follow
8979 immediately after the lop_post lopcode and its data. After this
8980 lopcode follows all symbols in a compressed format (*note
8981 Symbol-table::).
8983 `lop_end'
8984 0x980cYYZZ. The last lopcode in a program. It must follow the
8985 lop_stab lopcode and its data. The `YZ' field contains the number
8986 of 32-bit words of symbol table information after the preceding
8987 lop_stab lopcode.
8989 Note that the lopcode "fixups"; `lop_fixr', `lop_fixrx' and
8990 `lop_fixo' are not generated by BFD, but are handled. They are
8991 generated by `mmixal'.
8993 This trivial one-label, one-instruction file:
8995 :Main TRAP 1,2,3
8997 can be represented this way in mmo:
8999 0x98090101 - lop_pre, one 32-bit word with timestamp.
9000 <timestamp>
9001 0x98010002 - lop_loc, text segment, using a 64-bit address.

9003 0x00000000 - Address, high 32 bits.
9004 0x00000000 - Address, low 32 bits.

9024 3.5.2 Symbol table format
9025 -------------------------
9027 From mmixal.w (or really, the generated mmixal.tex) in
9028 `http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz'):
9029 "Symbols are stored and retrieved by means of a `ternary search trie',
9030 following ideas of Bentley and Sedgewick. (See ACM-SIAM Symp. on
9031 Discrete Algorithms `8' (1997), 360-369; R.Sedgewick, `Algorithms in C'
9032 (Reading, Mass. Addison-Wesley, 1998), `15.4'.) Each trie node stores
9033 a character, and there are branches to subtries for the cases where a
9034 given character is less than, equal to, or greater than the character
9035 in the trie. There also is a pointer to a symbol table entry if a
9036 symbol ends at the current node."
9038 So it's a tree encoded as a stream of bytes. The stream of bytes
9039 acts on a single virtual global symbol, adding and removing characters
9040 and signalling complete symbol points. Here, we read the stream and
9041 create symbols at the completion points.
9043 First, there's a control byte `m'. If any of the listed bits in `m'
9044 is nonzero, we execute what stands at the right, in the listed order:
9046 (MMO3_LEFT)
9047 0x40 - Traverse left trie.
9048 (Read a new command byte and recurse.)
9050 (MMO3_SYMBITS)
9051 0x2f - Read the next byte as a character and store it in the
9052 current character position; increment character position.
9053 Test the bits of `m':
9055 (MMO3_WCHAR)
9056 0x80 - The character is 16-bit (so read another byte,
9057 merge into current character.
9059 (MMO3_TYPEBITS)
9060 0xf - We have a complete symbol; parse the type, value
9061 and serial number and do what should be done
9062 with a symbol. The type and length information
9063 is in j = (m & 0xf).
9065 (MMO3_REGQUAL_BITS)
9066 j == 0xf: A register variable. The following
9067 byte tells which register.
9068 j <= 8: An absolute symbol. Read j bytes as the
9069 big-endian number the symbol equals.
9070 A j = 2 with two zero bytes denotes an
9071 unknown symbol.
9072 j > 8: As with j <= 8, but add (0x20 << 56)
9073 to the value in the following j - 8
9074 bytes.
9076 Then comes the serial number, as a variant of
9077 uleb128, but better named ubeb128:
9078 Read bytes and shift the previous value left 7
9079 (multiply by 128). Add in the new byte, repeat
9080 until a byte has bit 7 set. The serial number
9081 is the computed value minus 128.
9083 (MMO3_MIDDLE)
9084 0x20 - Traverse middle trie. (Read a new command byte
9085 and recurse.) Decrement character position.
9087 (MMO3_RIGHT)
9088 0x10 - Traverse right trie. (Read a new command byte and
9089 recurse.)
9091 Let's look again at the `lop_stab' for the trivial file (*note File
9092 layout::).
9094 0x980b0000 - lop_stab for ":Main" = 0, serial 1.
9095 0x203a4040
9096 0x10404020
9097 0x4d206120
9098 0x69016e00
9099 0x81000000
9101 This forms the trivial trie (note that the path between ":" and "M"
9102 is redundant):
9104 203a ":"
9105 40 /
9106 40 /
9107 10 \
9108 40 /
9109 40 /
9110 204d "M"
9111 2061 "a"
9112 2069 "i"
9113 016e "n" is the last character in a full symbol, and
9114 with a value represented in one byte.
9115 00 The value is 0.
9116 81 The serial number is 1.

9121 3.5.3 mmo section mapping
9122 -------------------------
9124 The implementation in BFD uses special data type 80 (decimal) to
9125 encapsulate and describe named sections, containing e.g. debug
9126 information. If needed, any datum in the encapsulation will be quoted
9127 using lop_quote. First comes a 32-bit word holding the number of
9128 32-bit words containing the zero-terminated zero-padded segment name.
9129 After the name there's a 32-bit word holding flags describing the
9130 section type. Then comes a 64-bit big-endian word with the section
9131 length (in bytes), then another with the section start address.
9132 Depending on the type of section, the contents might follow,
9133 zero-padded to 32-bit boundary. For a loadable section (such as data
9134 or code), the contents might follow at some later point, not
9135 necessarily immediately, as a lop_loc with the same start address as in
9136 the section description, followed by the contents. This in effect
9137 forms a descriptor that must be emitted before the actual contents.
9138 Sections described this way must not overlap.
9140 For areas that don't have such descriptors, synthetic sections are
9141 formed by BFD. Consecutive contents in the two memory areas
9142 `0x0000...00' to `0x01ff...ff' and `0x2000...00' to `0x20ff...ff' are
9143 entered in sections named `.text' and `.data' respectively. If an area
9144 is not otherwise described, but would together with a neighboring lower
9145 area be less than `0x40000000' bytes long, it is joined with the lower
9146 area and the gap is zero-filled. For other cases, a new section is
9147 formed, named `.MMIX.sec.N'. Here, N is a number, a running count
9148 through the mmo file, starting at 0.
9150 A loadable section specified as:
9152 .section secname,"ax"
9153 TETRA 1,2,3,4,-1,-2009
9154 BYTE 80
9156 and linked to address `0x4', is represented by the sequence:
9158 0x98080050 - lop_spec 80
9159 0x00000002 - two 32-bit words for the section name
9160 0x7365636e - "secn"
9161 0x616d6500 - "ame\0"
9162 0x00000033 - flags CODE, READONLY, LOAD, ALLOC
9163 0x00000000 - high 32 bits of section length
9164 0x0000001c - section length is 28 bytes; 6 * 4 + 1 + alignment to 32 bits
9165 0x00000000 - high 32 bits of section address
9166 0x00000004 - section address is 4
9167 0x98010002 - 64 bits with address of following data
9168 0x00000000 - high 32 bits of address
9169 0x00000004 - low 32 bits: data starts at address 4
9170 0x00000001 - 1
9171 0x00000002 - 2
9172 0x00000003 - 3
9173 0x00000004 - 4
9174 0xffffffff - -1
9175 0xfffff827 - -2009
9176 0x50000000 - 80 as a byte, padded with zeros.
9178 Note that the lop_spec wrapping does not include the section
9179 contents. Compare this to a non-loaded section specified as:
9181 .section thirdsec
9182 TETRA 200001,100002
9183 BYTE 38,40
9185 This, when linked to address `0x200000000000001c', is represented by:
9187 0x98080050 - lop_spec 80
9188 0x00000002 - two 32-bit words for the section name
9189 0x7365636e - "thir"
9190 0x616d6500 - "dsec"
9191 0x00000010 - flag READONLY
9192 0x00000000 - high 32 bits of section length
9193 0x0000000c - section length is 12 bytes; 2 * 4 + 2 + alignment to 32 bits
9194 0x20000000 - high 32 bits of address
9195 0x0000001c - low 32 bits of address 0x200000000000001c
9196 0x00030d41 - 200001
9197 0x000186a2 - 100002
9198 0x26280000 - 38, 40 as bytes, padded with zeros
9200 For the latter example, the section contents must not be loaded in
9201 memory, and is therefore specified as part of the special data. The
9202 address is usually unimportant but might provide information for e.g.
9203 the DWARF 2 debugging format.

9211 `http://fsf.org/'
9213 Everyone is permitted to copy and distribute verbatim copies
9214 of this license document, but changing it is not allowed.
9216 0. PREAMBLE
9218 The purpose of this License is to make a manual, textbook, or other
9219 functional and useful document "free" in the sense of freedom: to
9220 assure everyone the effective freedom to copy and redistribute it,
9221 with or without modifying it, either commercially or
9222 noncommercially. Secondarily, this License preserves for the
9223 author and publisher a way to get credit for their work, while not
9224 being considered responsible for modifications made by others.
9226 This License is a kind of "copyleft", which means that derivative
9227 works of the document must themselves be free in the same sense.
9228 It complements the GNU General Public License, which is a copyleft
9229 license designed for free software.
9231 We have designed this License in order to use it for manuals for
9232 free software, because free software needs free documentation: a
9233 free program should come with manuals providing the same freedoms
9234 that the software does. But this License is not limited to
9235 software manuals; it can be used for any textual work, regardless
9236 of subject matter or whether it is published as a printed book.
9237 We recommend this License principally for works whose purpose is
9238 instruction or reference.
9240 1. APPLICABILITY AND DEFINITIONS
9242 This License applies to any manual or other work, in any medium,
9243 that contains a notice placed by the copyright holder saying it
9244 can be distributed under the terms of this License. Such a notice
9245 grants a world-wide, royalty-free license, unlimited in duration,
9246 to use that work under the conditions stated herein. The
9247 "Document", below, refers to any such manual or work. Any member
9248 of the public is a licensee, and is addressed as "you". You
9249 accept the license if you copy, modify or distribute the work in a
9250 way requiring permission under copyright law.
9252 A "Modified Version" of the Document means any work containing the
9253 Document or a portion of it, either copied verbatim, or with
9254 modifications and/or translated into another language.
9256 A "Secondary Section" is a named appendix or a front-matter section
9257 of the Document that deals exclusively with the relationship of the
9258 publishers or authors of the Document to the Document's overall
9259 subject (or to related matters) and contains nothing that could
9260 fall directly within that overall subject. (Thus, if the Document
9261 is in part a textbook of mathematics, a Secondary Section may not
9262 explain any mathematics.) The relationship could be a matter of
9263 historical connection with the subject or with related matters, or
9264 of legal, commercial, philosophical, ethical or political position
9265 regarding them.
9267 The "Invariant Sections" are certain Secondary Sections whose
9268 titles are designated, as being those of Invariant Sections, in
9269 the notice that says that the Document is released under this
9270 License. If a section does not fit the above definition of
9271 Secondary then it is not allowed to be designated as Invariant.
9272 The Document may contain zero Invariant Sections. If the Document
9273 does not identify any Invariant Sections then there are none.
9275 The "Cover Texts" are certain short passages of text that are
9276 listed, as Front-Cover Texts or Back-Cover Texts, in the notice
9277 that says that the Document is released under this License. A
9278 Front-Cover Text may be at most 5 words, and a Back-Cover Text may
9279 be at most 25 words.
9281 A "Transparent" copy of the Document means a machine-readable copy,
9282 represented in a format whose specification is available to the
9283 general public, that is suitable for revising the document
9284 straightforwardly with generic text editors or (for images
9285 composed of pixels) generic paint programs or (for drawings) some
9286 widely available drawing editor, and that is suitable for input to
9287 text formatters or for automatic translation to a variety of
9288 formats suitable for input to text formatters. A copy made in an
9289 otherwise Transparent file format whose markup, or absence of
9290 markup, has been arranged to thwart or discourage subsequent
9291 modification by readers is not Transparent. An image format is
9292 not Transparent if used for any substantial amount of text. A
9293 copy that is not "Transparent" is called "Opaque".
9295 Examples of suitable formats for Transparent copies include plain
9296 ASCII without markup, Texinfo input format, LaTeX input format,
9297 SGML or XML using a publicly available DTD, and
9298 standard-conforming simple HTML, PostScript or PDF designed for
9299 human modification. Examples of transparent image formats include
9300 PNG, XCF and JPG. Opaque formats include proprietary formats that
9301 can be read and edited only by proprietary word processors, SGML or
9302 XML for which the DTD and/or processing tools are not generally
9303 available, and the machine-generated HTML, PostScript or PDF
9304 produced by some word processors for output purposes only.
9306 The "Title Page" means, for a printed book, the title page itself,
9307 plus such following pages as are needed to hold, legibly, the
9308 material this License requires to appear in the title page. For
9309 works in formats which do not have any title page as such, "Title
9310 Page" means the text near the most prominent appearance of the
9311 work's title, preceding the beginning of the body of the text.
9313 The "publisher" means any person or entity that distributes copies
9314 of the Document to the public.
9316 A section "Entitled XYZ" means a named subunit of the Document
9317 whose title either is precisely XYZ or contains XYZ in parentheses
9318 following text that translates XYZ in another language. (Here XYZ
9319 stands for a specific section name mentioned below, such as
9320 "Acknowledgements", "Dedications", "Endorsements", or "History".)
9321 To "Preserve the Title" of such a section when you modify the
9322 Document means that it remains a section "Entitled XYZ" according
9323 to this definition.
9325 The Document may include Warranty Disclaimers next to the notice
9326 which states that this License applies to the Document. These
9327 Warranty Disclaimers are considered to be included by reference in
9328 this License, but only as regards disclaiming warranties: any other
9329 implication that these Warranty Disclaimers may have is void and
9330 has no effect on the meaning of this License.
9332 2. VERBATIM COPYING
9334 You may copy and distribute the Document in any medium, either
9335 commercially or noncommercially, provided that this License, the
9336 copyright notices, and the license notice saying this License
9337 applies to the Document are reproduced in all copies, and that you
9338 add no other conditions whatsoever to those of this License. You
9339 may not use technical measures to obstruct or control the reading
9340 or further copying of the copies you make or distribute. However,
9341 you may accept compensation in exchange for copies. If you
9342 distribute a large enough number of copies you must also follow
9343 the conditions in section 3.
9345 You may also lend copies, under the same conditions stated above,
9346 and you may publicly display copies.
9348 3. COPYING IN QUANTITY
9350 If you publish printed copies (or copies in media that commonly
9351 have printed covers) of the Document, numbering more than 100, and
9352 the Document's license notice requires Cover Texts, you must
9353 enclose the copies in covers that carry, clearly and legibly, all
9354 these Cover Texts: Front-Cover Texts on the front cover, and
9355 Back-Cover Texts on the back cover. Both covers must also clearly
9356 and legibly identify you as the publisher of these copies. The
9357 front cover must present the full title with all words of the
9358 title equally prominent and visible. You may add other material
9359 on the covers in addition. Copying with changes limited to the
9360 covers, as long as they preserve the title of the Document and
9361 satisfy these conditions, can be treated as verbatim copying in
9362 other respects.
9364 If the required texts for either cover are too voluminous to fit
9365 legibly, you should put the first ones listed (as many as fit
9366 reasonably) on the actual cover, and continue the rest onto
9367 adjacent pages.
9369 If you publish or distribute Opaque copies of the Document
9370 numbering more than 100, you must either include a
9371 machine-readable Transparent copy along with each Opaque copy, or
9372 state in or with each Opaque copy a computer-network location from
9373 which the general network-using public has access to download
9374 using public-standard network protocols a complete Transparent
9375 copy of the Document, free of added material. If you use the
9376 latter option, you must take reasonably prudent steps, when you
9377 begin distribution of Opaque copies in quantity, to ensure that
9378 this Transparent copy will remain thus accessible at the stated
9379 location until at least one year after the last time you
9380 distribute an Opaque copy (directly or through your agents or
9381 retailers) of that edition to the public.
9383 It is requested, but not required, that you contact the authors of
9384 the Document well before redistributing any large number of
9385 copies, to give them a chance to provide you with an updated
9386 version of the Document.
9388 4. MODIFICATIONS
9390 You may copy and distribute a Modified Version of the Document
9391 under the conditions of sections 2 and 3 above, provided that you
9392 release the Modified Version under precisely this License, with
9393 the Modified Version filling the role of the Document, thus
9394 licensing distribution and modification of the Modified Version to
9395 whoever possesses a copy of it. In addition, you must do these
9396 things in the Modified Version:
9398 A. Use in the Title Page (and on the covers, if any) a title
9399 distinct from that of the Document, and from those of
9400 previous versions (which should, if there were any, be listed
9401 in the History section of the Document). You may use the
9402 same title as a previous version if the original publisher of
9403 that version gives permission.
9405 B. List on the Title Page, as authors, one or more persons or
9406 entities responsible for authorship of the modifications in
9407 the Modified Version, together with at least five of the
9408 principal authors of the Document (all of its principal
9409 authors, if it has fewer than five), unless they release you
9410 from this requirement.
9412 C. State on the Title page the name of the publisher of the
9413 Modified Version, as the publisher.
9415 D. Preserve all the copyright notices of the Document.
9417 E. Add an appropriate copyright notice for your modifications
9418 adjacent to the other copyright notices.
9420 F. Include, immediately after the copyright notices, a license
9421 notice giving the public permission to use the Modified
9422 Version under the terms of this License, in the form shown in
9423 the Addendum below.
9425 G. Preserve in that license notice the full lists of Invariant
9426 Sections and required Cover Texts given in the Document's
9427 license notice.
9429 H. Include an unaltered copy of this License.
9431 I. Preserve the section Entitled "History", Preserve its Title,
9432 and add to it an item stating at least the title, year, new
9433 authors, and publisher of the Modified Version as given on
9434 the Title Page. If there is no section Entitled "History" in
9435 the Document, create one stating the title, year, authors,
9436 and publisher of the Document as given on its Title Page,
9437 then add an item describing the Modified Version as stated in
9438 the previous sentence.
9440 J. Preserve the network location, if any, given in the Document
9441 for public access to a Transparent copy of the Document, and
9442 likewise the network locations given in the Document for
9443 previous versions it was based on. These may be placed in
9444 the "History" section. You may omit a network location for a
9445 work that was published at least four years before the
9446 Document itself, or if the original publisher of the version
9447 it refers to gives permission.
9449 K. For any section Entitled "Acknowledgements" or "Dedications",
9450 Preserve the Title of the section, and preserve in the
9451 section all the substance and tone of each of the contributor
9452 acknowledgements and/or dedications given therein.
9454 L. Preserve all the Invariant Sections of the Document,
9455 unaltered in their text and in their titles. Section numbers
9456 or the equivalent are not considered part of the section
9457 titles.
9459 M. Delete any section Entitled "Endorsements". Such a section
9460 may not be included in the Modified Version.
9462 N. Do not retitle any existing section to be Entitled
9463 "Endorsements" or to conflict in title with any Invariant
9464 Section.
9466 O. Preserve any Warranty Disclaimers.
9468 If the Modified Version includes new front-matter sections or
9469 appendices that qualify as Secondary Sections and contain no
9470 material copied from the Document, you may at your option
9471 designate some or all of these sections as invariant. To do this,
9472 add their titles to the list of Invariant Sections in the Modified
9473 Version's license notice. These titles must be distinct from any
9474 other section titles.
9476 You may add a section Entitled "Endorsements", provided it contains
9477 nothing but endorsements of your Modified Version by various
9478 parties--for example, statements of peer review or that the text
9479 has been approved by an organization as the authoritative
9480 definition of a standard.
9482 You may add a passage of up to five words as a Front-Cover Text,
9483 and a passage of up to 25 words as a Back-Cover Text, to the end
9484 of the list of Cover Texts in the Modified Version. Only one
9485 passage of Front-Cover Text and one of Back-Cover Text may be
9486 added by (or through arrangements made by) any one entity. If the
9487 Document already includes a cover text for the same cover,
9488 previously added by you or by arrangement made by the same entity
9489 you are acting on behalf of, you may not add another; but you may
9490 replace the old one, on explicit permission from the previous
9491 publisher that added the old one.
9493 The author(s) and publisher(s) of the Document do not by this
9494 License give permission to use their names for publicity for or to
9495 assert or imply endorsement of any Modified Version.
9497 5. COMBINING DOCUMENTS
9499 You may combine the Document with other documents released under
9500 this License, under the terms defined in section 4 above for
9501 modified versions, provided that you include in the combination
9502 all of the Invariant Sections of all of the original documents,
9503 unmodified, and list them all as Invariant Sections of your
9504 combined work in its license notice, and that you preserve all
9505 their Warranty Disclaimers.
9507 The combined work need only contain one copy of this License, and
9508 multiple identical Invariant Sections may be replaced with a single
9509 copy. If there are multiple Invariant Sections with the same name
9510 but different contents, make the title of each such section unique
9511 by adding at the end of it, in parentheses, the name of the
9512 original author or publisher of that section if known, or else a
9513 unique number. Make the same adjustment to the section titles in
9514 the list of Invariant Sections in the license notice of the
9515 combined work.
9517 In the combination, you must combine any sections Entitled
9518 "History" in the various original documents, forming one section
9519 Entitled "History"; likewise combine any sections Entitled
9520 "Acknowledgements", and any sections Entitled "Dedications". You
9521 must delete all sections Entitled "Endorsements."
9523 6. COLLECTIONS OF DOCUMENTS
9525 You may make a collection consisting of the Document and other
9526 documents released under this License, and replace the individual
9527 copies of this License in the various documents with a single copy
9528 that is included in the collection, provided that you follow the
9529 rules of this License for verbatim copying of each of the
9530 documents in all other respects.
9532 You may extract a single document from such a collection, and
9533 distribute it individually under this License, provided you insert
9534 a copy of this License into the extracted document, and follow
9535 this License in all other respects regarding verbatim copying of
9536 that document.
9538 7. AGGREGATION WITH INDEPENDENT WORKS
9540 A compilation of the Document or its derivatives with other
9541 separate and independent documents or works, in or on a volume of
9542 a storage or distribution medium, is called an "aggregate" if the
9543 copyright resulting from the compilation is not used to limit the
9544 legal rights of the compilation's users beyond what the individual
9545 works permit. When the Document is included in an aggregate, this
9546 License does not apply to the other works in the aggregate which
9547 are not themselves derivative works of the Document.
9549 If the Cover Text requirement of section 3 is applicable to these
9550 copies of the Document, then if the Document is less than one half
9551 of the entire aggregate, the Document's Cover Texts may be placed
9552 on covers that bracket the Document within the aggregate, or the
9553 electronic equivalent of covers if the Document is in electronic
9554 form. Otherwise they must appear on printed covers that bracket
9555 the whole aggregate.
9557 8. TRANSLATION
9559 Translation is considered a kind of modification, so you may
9560 distribute translations of the Document under the terms of section
9561 4. Replacing Invariant Sections with translations requires special
9562 permission from their copyright holders, but you may include
9563 translations of some or all Invariant Sections in addition to the
9564 original versions of these Invariant Sections. You may include a
9565 translation of this License, and all the license notices in the
9566 Document, and any Warranty Disclaimers, provided that you also
9567 include the original English version of this License and the
9568 original versions of those notices and disclaimers. In case of a
9569 disagreement between the translation and the original version of
9570 this License or a notice or disclaimer, the original version will
9571 prevail.
9573 If a section in the Document is Entitled "Acknowledgements",
9574 "Dedications", or "History", the requirement (section 4) to
9575 Preserve its Title (section 1) will typically require changing the
9576 actual title.
9578 9. TERMINATION
9580 You may not copy, modify, sublicense, or distribute the Document
9581 except as expressly provided under this License. Any attempt
9582 otherwise to copy, modify, sublicense, or distribute it is void,
9583 and will automatically terminate your rights under this License.
9585 However, if you cease all violation of this License, then your
9586 license from a particular copyright holder is reinstated (a)
9587 provisionally, unless and until the copyright holder explicitly
9588 and finally terminates your license, and (b) permanently, if the
9589 copyright holder fails to notify you of the violation by some
9590 reasonable means prior to 60 days after the cessation.
9592 Moreover, your license from a particular copyright holder is
9593 reinstated permanently if the copyright holder notifies you of the
9594 violation by some reasonable means, this is the first time you have
9595 received notice of violation of this License (for any work) from
9596 that copyright holder, and you cure the violation prior to 30 days
9597 after your receipt of the notice.
9599 Termination of your rights under this section does not terminate
9600 the licenses of parties who have received copies or rights from
9601 you under this License. If your rights have been terminated and
9602 not permanently reinstated, receipt of a copy of some or all of
9603 the same material does not give you any rights to use it.
9605 10. FUTURE REVISIONS OF THIS LICENSE
9607 The Free Software Foundation may publish new, revised versions of
9608 the GNU Free Documentation License from time to time. Such new
9609 versions will be similar in spirit to the present version, but may
9610 differ in detail to address new problems or concerns. See
9611 `http://www.gnu.org/copyleft/'.
9613 Each version of the License is given a distinguishing version
9614 number. If the Document specifies that a particular numbered
9615 version of this License "or any later version" applies to it, you
9616 have the option of following the terms and conditions either of
9617 that specified version or of any later version that has been
9618 published (not as a draft) by the Free Software Foundation. If
9619 the Document does not specify a version number of this License,
9620 you may choose any version ever published (not as a draft) by the
9621 Free Software Foundation. If the Document specifies that a proxy
9622 can decide which future versions of this License can be used, that
9623 proxy's public statement of acceptance of a version permanently
9624 authorizes you to choose that version for the Document.
9626 11. RELICENSING
9628 "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
9629 World Wide Web server that publishes copyrightable works and also
9630 provides prominent facilities for anybody to edit those works. A
9631 public wiki that anybody can edit is an example of such a server.
9632 A "Massive Multiauthor Collaboration" (or "MMC") contained in the
9633 site means any set of copyrightable works thus published on the MMC
9634 site.
9636 "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
9637 license published by Creative Commons Corporation, a not-for-profit
9638 corporation with a principal place of business in San Francisco,
9639 California, as well as future copyleft versions of that license
9640 published by that same organization.
9642 "Incorporate" means to publish or republish a Document, in whole or
9643 in part, as part of another Document.
9645 An MMC is "eligible for relicensing" if it is licensed under this
9646 License, and if all works that were first published under this
9647 License somewhere other than this MMC, and subsequently
9648 incorporated in whole or in part into the MMC, (1) had no cover
9649 texts or invariant sections, and (2) were thus incorporated prior
9650 to November 1, 2008.
9652 The operator of an MMC Site may republish an MMC contained in the
9653 site under CC-BY-SA on the same site at any time before August 1,
9654 2009, provided the MMC is eligible for relicensing.
9657 ADDENDUM: How to use this License for your documents
9658 ====================================================
9660 To use this License in a document you have written, include a copy of
9661 the License in the document and put the following copyright and license
9662 notices just after the title page:
9664 Copyright (C) YEAR YOUR NAME.
9665 Permission is granted to copy, distribute and/or modify this document
9666 under the terms of the GNU Free Documentation License, Version 1.3
9667 or any later version published by the Free Software Foundation;
9668 with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
9669 Texts. A copy of the license is included in the section entitled ``GNU
9670 Free Documentation License''.
9672 If you have Invariant Sections, Front-Cover Texts and Back-Cover
9673 Texts, replace the "with...Texts." line with this:
9675 with the Invariant Sections being LIST THEIR TITLES, with
9676 the Front-Cover Texts being LIST, and with the Back-Cover Texts
9677 being LIST.
9679 If you have Invariant Sections without Cover Texts, or some other
9680 combination of the three, merge those two alternatives to suit the
9681 situation.
9683 If your document contains nontrivial examples of program code, we
9684 recommend releasing these examples in parallel under your choice of
9685 free software license, such as the GNU General Public License, to
9686 permit their use in free software.
