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).

560 2.2 Error reporting
561 ===================
563 Most BFD functions return nonzero on success (check their individual
564 documentation for precise semantics). On an error, they call
565 `bfd_set_error' to set an error condition that callers can check by
566 calling `bfd_get_error'. If that returns `bfd_error_system_call', then
567 check `errno'.
569 The easiest way to report a BFD error to the user is to use
570 `bfd_perror'.
572 2.2.1 Type `bfd_error_type'

616 *Synopsis*
617 void bfd_set_error (bfd_error_type error_tag, ...);
618 *Description*
619 Set the BFD error condition to be ERROR_TAG. If ERROR_TAG is
620 bfd_error_on_input, then this function takes two more parameters, the
621 input bfd where the error occurred, and the bfd_error_type error.
623 2.2.1.3 `bfd_errmsg'
624 ....................
626 *Synopsis*
627 const char *bfd_errmsg (bfd_error_type error_tag);
628 *Description*
629 Return a string describing the error ERROR_TAG, or the system error if
630 ERROR_TAG is `bfd_error_system_call'.
632 2.2.1.4 `bfd_perror'
633 ....................
635 *Synopsis*
636 void bfd_perror (const char *message);
637 *Description*
638 Print to the standard error stream a string describing the last BFD
639 error that occurred, or the last system error if the last BFD error was
640 a system call failure. If MESSAGE is non-NULL and non-empty, the error
641 string printed is preceded by MESSAGE, a colon, and a space. It is
642 followed by a newline.
644 2.2.2 BFD error handler
645 -----------------------
647 Some BFD functions want to print messages describing the problem. They
648 call a BFD error handler function. This function may be overridden by
649 the program.
651 The BFD error handler acts like printf.
654 typedef void (*bfd_error_handler_type) (const char *, ...);
656 2.2.2.1 `bfd_set_error_handler'
657 ...............................
659 *Synopsis*

667 *Synopsis*
668 void bfd_set_error_program_name (const char *);
669 *Description*
670 Set the program name to use when printing a BFD error. This is printed
671 before the error message followed by a colon and space. The string
672 must not be changed after it is passed to this function.
674 2.2.2.3 `bfd_get_error_handler'

682 2.3 Miscellaneous
683 =================
685 2.3.1 Miscellaneous functions
686 -----------------------------
688 2.3.1.1 `bfd_get_reloc_upper_bound'

693 *Description*
694 Return the number of bytes required to store the relocation information
695 associated with section SECT attached to bfd ABFD. If an error occurs,
696 return -1.
698 2.3.1.2 `bfd_canonicalize_reloc'
699 ................................
701 *Synopsis*
702 long bfd_canonicalize_reloc
703 (bfd *abfd, asection *sec, arelent **loc, asymbol **syms);
704 *Description*
705 Call the back end associated with the open BFD ABFD and translate the
706 external form of the relocation information attached to SEC into the
707 internal canonical form. Place the table into memory at LOC, which has
708 been preallocated, usually by a call to `bfd_get_reloc_upper_bound'.
709 Returns the number of relocs, or -1 on error.
711 The SYMS table is also needed for horrible internal magic reasons.
713 2.3.1.3 `bfd_set_reloc'
714 .......................
716 *Synopsis*
717 void bfd_set_reloc
718 (bfd *abfd, asection *sec, arelent **rel, unsigned int count);
719 *Description*
720 Set the relocation pointer and count within section SEC to the values
721 REL and COUNT. The argument ABFD is ignored.
723 2.3.1.4 `bfd_set_file_flags'
724 ............................
726 *Synopsis*
727 bfd_boolean bfd_set_file_flags (bfd *abfd, flagword flags);
728 *Description*
729 Set the flag word in the BFD ABFD to the value FLAGS.
731 Possible errors are:
732 * `bfd_error_wrong_format' - The target bfd was not of object format.
734 * `bfd_error_invalid_operation' - The target bfd was open for
735 reading.
737 * `bfd_error_invalid_operation' - The flag word contained a bit
738 which was not applicable to the type of file. E.g., an attempt
739 was made to set the `D_PAGED' bit on a BFD format which does not
740 support demand paging.
742 2.3.1.5 `bfd_get_arch_size'
743 ...........................
745 *Synopsis*
746 int bfd_get_arch_size (bfd *abfd);
747 *Description*
748 Returns the architecture address size, in bits, as determined by the
749 object file's format. For ELF, this information is included in the
750 header.
752 *Returns*
753 Returns the arch size in bits if known, `-1' otherwise.
755 2.3.1.6 `bfd_get_sign_extend_vma'
756 .................................
758 *Synopsis*
759 int bfd_get_sign_extend_vma (bfd *abfd);
760 *Description*
761 Indicates if the target architecture "naturally" sign extends an
762 address. Some architectures implicitly sign extend address values when
763 they are converted to types larger than the size of an address. For
764 instance, bfd_get_start_address() will return an address sign extended
765 to fill a bfd_vma when this is the case.
767 *Returns*
768 Returns `1' if the target architecture is known to sign extend
769 addresses, `0' if the target architecture is known to not sign extend
770 addresses, and `-1' otherwise.
772 2.3.1.7 `bfd_set_start_address'
773 ...............................
775 *Synopsis*
776 bfd_boolean bfd_set_start_address (bfd *abfd, bfd_vma vma);
777 *Description*
778 Make VMA the entry point of output BFD ABFD.
780 *Returns*
781 Returns `TRUE' on success, `FALSE' otherwise.
783 2.3.1.8 `bfd_get_gp_size'
784 .........................
786 *Synopsis*
787 unsigned int bfd_get_gp_size (bfd *abfd);
788 *Description*
789 Return the maximum size of objects to be optimized using the GP
790 register under MIPS ECOFF. This is typically set by the `-G' argument
791 to the compiler, assembler or linker.
793 2.3.1.9 `bfd_set_gp_size'
794 .........................
796 *Synopsis*
797 void bfd_set_gp_size (bfd *abfd, unsigned int i);
798 *Description*
799 Set the maximum size of objects to be optimized using the GP register
800 under ECOFF or MIPS ELF. This is typically set by the `-G' argument to
801 the compiler, assembler or linker.
803 2.3.1.10 `bfd_scan_vma'
804 .......................
806 *Synopsis*
807 bfd_vma bfd_scan_vma (const char *string, const char **end, int base);
808 *Description*
809 Convert, like `strtoul', a numerical expression STRING into a `bfd_vma'
810 integer, and return that integer. (Though without as many bells and
811 whistles as `strtoul'.) The expression is assumed to be unsigned
812 (i.e., positive). If given a BASE, it is used as the base for
813 conversion. A base of 0 causes the function to interpret the string in
814 hex if a leading "0x" or "0X" is found, otherwise in octal if a leading
815 zero is found, otherwise in decimal.
817 If the value would overflow, the maximum `bfd_vma' value is returned.
819 2.3.1.11 `bfd_copy_private_header_data'
820 .......................................
822 *Synopsis*
823 bfd_boolean bfd_copy_private_header_data (bfd *ibfd, bfd *obfd);
824 *Description*
825 Copy private BFD header information from the BFD IBFD to the the BFD
826 OBFD. This copies information that may require sections to exist, but
827 does not require symbol tables. Return `true' on success, `false' on
828 error. Possible error returns are:
830 * `bfd_error_no_memory' - Not enough memory exists to create private
831 data for OBFD.

985 When more than one machine code number is available for the same
986 machine type, this function can be used to switch between the preferred
987 one (alternative == 0) and any others. Currently, only ELF supports

1003 ............................
1005 *Synopsis*
1006 bfd_boolean bfd_preserve_save (bfd *, struct bfd_preserve *);
1007 *Description*
1008 When testing an object for compatibility with a particular target
1009 back-end, the back-end object_p function needs to set up certain fields
1010 in the bfd on successfully recognizing the object. This typically
1011 happens in a piecemeal fashion, with failures possible at many points.
1012 On failure, the bfd is supposed to be restored to its initial state,
1013 which is virtually impossible. However, restoring a subset of the bfd
1014 state works in practice. This function stores the subset and
1015 reinitializes the bfd.
1017 2.3.1.18 `bfd_preserve_restore'
1018 ...............................
1020 *Synopsis*
1021 void bfd_preserve_restore (bfd *, struct bfd_preserve *);
1022 *Description*
1023 This function restores bfd state saved by bfd_preserve_save. If MARKER
1024 is non-NULL in struct bfd_preserve then that block and all subsequently
1025 bfd_alloc'd memory is freed.
1027 2.3.1.19 `bfd_preserve_finish'
1028 ..............................
1030 *Synopsis*
1031 void bfd_preserve_finish (bfd *, struct bfd_preserve *);
1032 *Description*
1033 This function should be called when the bfd state saved by
1034 bfd_preserve_save is no longer needed. ie. when the back-end object_p
1035 function returns with success.
1037 2.3.1.20 `bfd_emul_get_maxpagesize'

1078 .......................
1080 *Synopsis*
1081 char *bfd_demangle (bfd *, const char *, int);
1082 *Description*
1083 Wrapper around cplus_demangle. Strips leading underscores and other
1084 such chars that would otherwise confuse the demangler. If passed a g++
1085 v3 ABI mangled name, returns a buffer allocated with malloc holding the
1086 demangled name. Returns NULL otherwise and on memory alloc failure.
1088 2.3.1.25 `struct bfd_iovec'

1091 *Description*
1092 The `struct bfd_iovec' contains the internal file I/O class. Each
1093 `BFD' has an instance of this class and all file I/O is routed through
1094 it (it is assumed that the instance implements all methods listed
1095 below).

1099 prefix is prepended to each method name. */

1118 2.3.1.26 `bfd_get_mtime'
1119 ........................
1121 *Synopsis*
1122 long bfd_get_mtime (bfd *abfd);
1123 *Description*
1124 Return the file modification time (as read from the file system, or
1125 from the archive header for archive members).
1127 2.3.1.27 `bfd_get_size'
1128 .......................
1130 *Synopsis*
1131 file_ptr bfd_get_size (bfd *abfd);
1132 *Description*
1133 Return the file size (as read from file system) for the file associated
1134 with BFD ABFD.
1136 The initial motivation for, and use of, this routine is not so we
1137 can get the exact size of the object the BFD applies to, since that
1138 might not be generally possible (archive members for example). It
1139 would be ideal if someone could eventually modify it so that such
1140 results were guaranteed.
1142 Instead, we want to ask questions like "is this NNN byte sized
1143 object I'm about to try read from file offset YYY reasonable?" As as
1144 example of where we might do this, some object formats use string
1145 tables for which the first `sizeof (long)' bytes of the table contain
1146 the size of the table itself, including the size bytes. If an
1147 application tries to read what it thinks is one of these string tables,
1148 without some way to validate the size, and for some reason the size is
1149 wrong (byte swapping error, wrong location for the string table, etc.),
1150 the only clue is likely to be a read error when it tries to read the
1151 table, or a "virtual memory exhausted" error when it tries to allocate
1152 15 bazillon bytes of space for the 15 bazillon byte table it is about
1153 to read. This function at least allows us to answer the question, "is
1154 the size reasonable?".

1177 2.4 Memory Usage
1178 ================
1180 BFD keeps all of its internal structures in obstacks. There is one
1181 obstack per open BFD file, into which the current state is stored. When
1182 a BFD is closed, the obstack is deleted, and so everything which has
1183 been allocated by BFD for the closing file is thrown away.
1185 BFD does not free anything created by an application, but pointers
1186 into `bfd' structures become invalid on a `bfd_close'; for example,
1187 after a `bfd_close' the vector passed to `bfd_canonicalize_symtab' is
1188 still around, since it has been allocated by the application, but the
1189 data that it pointed to are lost.
1191 The general rule is to not close a BFD until all operations dependent
1192 upon data from the BFD have been completed, or all the data from within
1193 the file has been copied. To help with the management of memory, there
1194 is a function (`bfd_alloc_size') which returns the number of bytes in
1195 obstacks associated with the supplied BFD. This could be used to select
1196 the greediest open BFD, close it to reclaim the memory, perform some
1197 operation and reopen the BFD again, to get a fresh copy of the data
1198 structures.

1223 2.6 Sections
1224 ============
1226 The raw data contained within a BFD is maintained through the section
1227 abstraction. A single BFD may have any number of sections. It keeps
1228 hold of them by pointing to the first; each one points to the next in
1229 the list.
1231 Sections are supported in BFD in `section.c'.

1243 2.6.1 Section input
1244 -------------------
1246 When a BFD is opened for reading, the section structures are created
1247 and attached to the BFD.
1249 Each section has a name which describes the section in the outside
1250 world--for example, `a.out' would contain at least three sections,
1251 called `.text', `.data' and `.bss'.
1253 Names need not be unique; for example a COFF file may have several
1254 sections named `.data'.
1256 Sometimes a BFD will contain more than the "natural" number of
1257 sections. A back end may attach other sections containing constructor
1258 data, or an application may add a section (using `bfd_make_section') to
1259 the sections attached to an already open BFD. For example, the linker
1260 creates an extra section `COMMON' for each input file's BFD to hold
1261 information about common storage.
1263 The raw data is not necessarily read in when the section descriptor
1264 is created. Some targets may leave the data in place until a
1265 `bfd_get_section_contents' call is made. Other back ends may read in
1266 all the data at once. For example, an S-record file has to be read
1267 once to determine the size of the data. An IEEE-695 file doesn't
1268 contain raw data in sections, but data and relocation expressions
1269 intermixed, so the data area has to be parsed to get out the data and
1270 relocations.

1273 File: bfd.info, Node: Section Output, Next: typedef asection, Prev: Section Input, Up: Sections
1275 2.6.2 Section output
1276 --------------------
1278 To write a new object style BFD, the various sections to be written
1279 have to be created. They are attached to the BFD in the same way as
1280 input sections; data is written to the sections using
1281 `bfd_set_section_contents'.
1283 Any program that creates or combines sections (e.g., the assembler
1284 and linker) must use the `asection' fields `output_section' and
1285 `output_offset' to indicate the file sections to which each section
1286 must be written. (If the section is being created from scratch,
1287 `output_section' should probably point to the section itself and
1288 `output_offset' should probably be zero.)
1290 The data to be written comes from input sections attached (via
1291 `output_section' pointers) to the output sections. The output section
1292 structure can be considered a filter for the input section: the output
1293 section determines the vma of the output data and the name, but the
1294 input section determines the offset into the output section of the data
1295 to be written.
1297 E.g., to create a section "O", starting at 0x100, 0x123 long,
1298 containing two subsections, "A" at offset 0x0 (i.e., at vma 0x100) and
1299 "B" at offset 0x20 (i.e., at vma 0x120) the `asection' structures would
1300 look like:
1302 section name "A"
1303 output_offset 0x00
1304 size 0x20
1305 output_section -----------> section name "O"
1306 | vma 0x100
1307 section name "B" | size 0x123
1308 output_offset 0x20 |
1309 size 0x103 |
1310 output_section --------|
1312 2.6.3 Link orders
1313 -----------------
1315 The data within a section is stored in a "link_order". These are much
1316 like the fixups in `gas'. The link_order abstraction allows a section
1317 to grow and shrink within itself.
1319 A link_order knows how big it is, and which is the next link_order
1320 and where the raw data for it is; it also points to a list of
1321 relocations which apply to it.
1323 The link_order is used by the linker to perform relaxing on final
1324 code. The compiler creates code which is as big as necessary to make
1325 it work without relaxing, and the user can select whether to relax.
1326 Sometimes relaxing takes a lot of time. The linker runs around the
1327 relocations to see if any are attached to data which can be shrunk, if
1328 so it does it on a link_order by link_order basis.

1862 2.6.5 Section prototypes
1863 ------------------------
1865 These are the functions exported by the section handling part of BFD.
1867 2.6.5.1 `bfd_section_list_clear'
1868 ................................
1870 *Synopsis*
1871 void bfd_section_list_clear (bfd *);
1872 *Description*
1873 Clears the section list, and also resets the section count and hash
1874 table entries.
1876 2.6.5.2 `bfd_get_section_by_name'
1877 .................................
1879 *Synopsis*
1880 asection *bfd_get_section_by_name (bfd *abfd, const char *name);
1881 *Description*
1882 Run through ABFD and return the one of the `asection's whose name
1883 matches NAME, otherwise `NULL'. *Note Sections::, for more information.
1885 This should only be used in special cases; the normal way to process
1886 all sections of a given name is to use `bfd_map_over_sections' and
1887 `strcmp' on the name (or better yet, base it on the section flags or
1888 something else) for each section.
1890 2.6.5.3 `bfd_get_section_by_name_if'
1891 ....................................
1893 *Synopsis*
1894 asection *bfd_get_section_by_name_if
1895 (bfd *abfd,
1896 const char *name,
1897 bfd_boolean (*func) (bfd *abfd, asection *sect, void *obj),
1898 void *obj);
1899 *Description*
1900 Call the provided function FUNC for each section attached to the BFD
1901 ABFD whose name matches NAME, passing OBJ as an argument. The function
1902 will be called as if by
1904 func (abfd, the_section, obj);
1906 It returns the first section for which FUNC returns true, otherwise
1907 `NULL'.
1909 2.6.5.4 `bfd_get_unique_section_name'
1910 .....................................
1912 *Synopsis*
1913 char *bfd_get_unique_section_name
1914 (bfd *abfd, const char *templat, int *count);
1915 *Description*
1916 Invent a section name that is unique in ABFD by tacking a dot and a
1917 digit suffix onto the original TEMPLAT. If COUNT is non-NULL, then it
1918 specifies the first number tried as a suffix to generate a unique name.
1919 The value pointed to by COUNT will be incremented in this case.
1921 2.6.5.5 `bfd_make_section_old_way'
1922 ..................................
1924 *Synopsis*
1925 asection *bfd_make_section_old_way (bfd *abfd, const char *name);
1926 *Description*
1927 Create a new empty section called NAME and attach it to the end of the
1928 chain of sections for the BFD ABFD. An attempt to create a section with
1929 a name which is already in use returns its pointer without changing the
1930 section chain.
1932 It has the funny name since this is the way it used to be before it
1933 was rewritten....
1935 Possible errors are:
1936 * `bfd_error_invalid_operation' - If output has already started for
1937 this BFD.
1939 * `bfd_error_no_memory' - If memory allocation fails.
1941 2.6.5.6 `bfd_make_section_anyway_with_flags'
1942 ............................................
1944 *Synopsis*
1945 asection *bfd_make_section_anyway_with_flags
1946 (bfd *abfd, const char *name, flagword flags);
1947 *Description*
1948 Create a new empty section called NAME and attach it to the end of the
1949 chain of sections for ABFD. Create a new section even if there is
1950 already a section with that name. Also set the attributes of the new
1951 section to the value FLAGS.
1953 Return `NULL' and set `bfd_error' on error; possible errors are:
1954 * `bfd_error_invalid_operation' - If output has already started for
1955 ABFD.
1957 * `bfd_error_no_memory' - If memory allocation fails.
1959 2.6.5.7 `bfd_make_section_anyway'
1960 .................................
1962 *Synopsis*
1963 asection *bfd_make_section_anyway (bfd *abfd, const char *name);
1964 *Description*
1965 Create a new empty section called NAME and attach it to the end of the
1966 chain of sections for ABFD. Create a new section even if there is
1967 already a section with that name.
1969 Return `NULL' and set `bfd_error' on error; possible errors are:
1970 * `bfd_error_invalid_operation' - If output has already started for
1971 ABFD.
1973 * `bfd_error_no_memory' - If memory allocation fails.
1975 2.6.5.8 `bfd_make_section_with_flags'
1976 .....................................
1978 *Synopsis*
1979 asection *bfd_make_section_with_flags
1980 (bfd *, const char *name, flagword flags);
1981 *Description*
1982 Like `bfd_make_section_anyway', but return `NULL' (without calling
1983 bfd_set_error ()) without changing the section chain if there is
1984 already a section named NAME. Also set the attributes of the new
1985 section to the value FLAGS. If there is an error, return `NULL' and set
1986 `bfd_error'.
1988 2.6.5.9 `bfd_make_section'
1989 ..........................
1991 *Synopsis*
1992 asection *bfd_make_section (bfd *, const char *name);
1993 *Description*
1994 Like `bfd_make_section_anyway', but return `NULL' (without calling
1995 bfd_set_error ()) without changing the section chain if there is
1996 already a section named NAME. If there is an error, return `NULL' and
1997 set `bfd_error'.
1999 2.6.5.10 `bfd_set_section_flags'
2000 ................................
2002 *Synopsis*
2003 bfd_boolean bfd_set_section_flags
2004 (bfd *abfd, asection *sec, flagword flags);
2005 *Description*
2006 Set the attributes of the section SEC in the BFD ABFD to the value
2007 FLAGS. Return `TRUE' on success, `FALSE' on error. Possible error
2008 returns are:
2010 * `bfd_error_invalid_operation' - The section cannot have one or
2011 more of the attributes requested. For example, a .bss section in
2012 `a.out' may not have the `SEC_HAS_CONTENTS' field set.
2014 2.6.5.11 `bfd_map_over_sections'
2015 ................................
2017 *Synopsis*
2018 void bfd_map_over_sections
2019 (bfd *abfd,
2020 void (*func) (bfd *abfd, asection *sect, void *obj),
2021 void *obj);
2022 *Description*
2023 Call the provided function FUNC for each section attached to the BFD
2024 ABFD, passing OBJ as an argument. The function will be called as if by
2026 func (abfd, the_section, obj);
2028 This is the preferred method for iterating over sections; an
2029 alternative would be to use a loop:
2031 section *p;
2032 for (p = abfd->sections; p != NULL; p = p->next)
2033 func (abfd, p, ...)
2035 2.6.5.12 `bfd_sections_find_if'
2036 ...............................
2038 *Synopsis*
2039 asection *bfd_sections_find_if
2040 (bfd *abfd,
2041 bfd_boolean (*operation) (bfd *abfd, asection *sect, void *obj),
2042 void *obj);
2043 *Description*
2044 Call the provided function OPERATION for each section attached to the
2045 BFD ABFD, passing OBJ as an argument. The function will be called as if
2046 by
2048 operation (abfd, the_section, obj);
2050 It returns the first section for which OPERATION returns true.
2052 2.6.5.13 `bfd_set_section_size'
2053 ...............................
2055 *Synopsis*
2056 bfd_boolean bfd_set_section_size
2057 (bfd *abfd, asection *sec, bfd_size_type val);
2058 *Description*
2059 Set SEC to the size VAL. If the operation is ok, then `TRUE' is
2060 returned, else `FALSE'.
2062 Possible error returns:
2063 * `bfd_error_invalid_operation' - Writing has started to the BFD, so
2064 setting the size is invalid.
2066 2.6.5.14 `bfd_set_section_contents'
2067 ...................................
2069 *Synopsis*
2070 bfd_boolean bfd_set_section_contents
2071 (bfd *abfd, asection *section, const void *data,
2072 file_ptr offset, bfd_size_type count);
2073 *Description*
2074 Sets the contents of the section SECTION in BFD ABFD to the data
2075 starting in memory at DATA. The data is written to the output section
2076 starting at offset OFFSET for COUNT octets.
2078 Normally `TRUE' is returned, else `FALSE'. Possible error returns
2079 are:
2080 * `bfd_error_no_contents' - The output section does not have the
2081 `SEC_HAS_CONTENTS' attribute, so nothing can be written to it.
2083 * and some more too
2084 This routine is front end to the back end function
2085 `_bfd_set_section_contents'.
2087 2.6.5.15 `bfd_get_section_contents'
2088 ...................................
2090 *Synopsis*
2091 bfd_boolean bfd_get_section_contents
2092 (bfd *abfd, asection *section, void *location, file_ptr offset,
2093 bfd_size_type count);
2094 *Description*
2095 Read data from SECTION in BFD ABFD into memory starting at LOCATION.
2096 The data is read at an offset of OFFSET from the start of the input
2097 section, and is read for COUNT bytes.
2099 If the contents of a constructor with the `SEC_CONSTRUCTOR' flag set
2100 are requested or if the section does not have the `SEC_HAS_CONTENTS'
2101 flag set, then the LOCATION is filled with zeroes. If no errors occur,
2102 `TRUE' is returned, else `FALSE'.
2104 2.6.5.16 `bfd_malloc_and_get_section'
2105 .....................................
2107 *Synopsis*
2108 bfd_boolean bfd_malloc_and_get_section
2109 (bfd *abfd, asection *section, bfd_byte **buf);
2110 *Description*
2111 Read all data from SECTION in BFD ABFD into a buffer, *BUF, malloc'd by
2112 this function.
2114 2.6.5.17 `bfd_copy_private_section_data'
2115 ........................................
2117 *Synopsis*
2118 bfd_boolean bfd_copy_private_section_data
2119 (bfd *ibfd, asection *isec, bfd *obfd, asection *osec);
2120 *Description*
2121 Copy private section information from ISEC in the BFD IBFD to the
2122 section OSEC in the BFD OBFD. Return `TRUE' on success, `FALSE' on
2123 error. Possible error returns are:
2125 * `bfd_error_no_memory' - Not enough memory exists to create private
2126 data for OSEC.

2151 2.7 Symbols
2152 ===========
2154 BFD tries to maintain as much symbol information as it can when it
2155 moves information from file to file. BFD passes information to
2156 applications though the `asymbol' structure. When the application
2157 requests the symbol table, BFD reads the table in the native form and
2158 translates parts of it into the internal format. To maintain more than
2159 the information passed to applications, some targets keep some
2160 information "behind the scenes" in a structure only the particular back
2161 end knows about. For example, the coff back end keeps the original
2162 symbol table structure as well as the canonical structure when a BFD is
2163 read in. On output, the coff back end can reconstruct the output symbol
2164 table so that no information is lost, even information unique to coff
2165 which BFD doesn't know or understand. If a coff symbol table were read,
2166 but were written through an a.out back end, all the coff specific
2167 information would be lost. The symbol table of a BFD is not necessarily
2168 read in until a canonicalize request is made. Then the BFD back end
2169 fills in a table provided by the application with pointers to the
2170 canonical information. To output symbols, the application provides BFD
2171 with a table of pointers to pointers to `asymbol's. This allows
2172 applications like the linker to output a symbol as it was read, since
2173 the "behind the scenes" information will be still available.

2186 2.7.1 Reading symbols
2187 ---------------------
2189 There are two stages to reading a symbol table from a BFD: allocating
2190 storage, and the actual reading process. This is an excerpt from an
2191 application which reads the symbol table:
2193 long storage_needed;
2194 asymbol **symbol_table;
2195 long number_of_symbols;
2196 long i;
2198 storage_needed = bfd_get_symtab_upper_bound (abfd);
2200 if (storage_needed < 0)
2201 FAIL
2203 if (storage_needed == 0)
2204 return;
2206 symbol_table = xmalloc (storage_needed);
2207 ...
2208 number_of_symbols =
2209 bfd_canonicalize_symtab (abfd, symbol_table);
2211 if (number_of_symbols < 0)
2212 FAIL
2214 for (i = 0; i < number_of_symbols; i++)
2215 process_symbol (symbol_table[i]);
2217 All storage for the symbols themselves is in an objalloc connected
2218 to the BFD; it is freed when the BFD is closed.
2220 \x1f
2221 File: bfd.info, Node: Writing Symbols, Next: Mini Symbols, Prev: Reading Symbols, Up: Symbols
2223 2.7.2 Writing symbols
2224 ---------------------
2226 Writing of a symbol table is automatic when a BFD open for writing is
2227 closed. The application attaches a vector of pointers to pointers to
2228 symbols to the BFD being written, and fills in the symbol count. The
2229 close and cleanup code reads through the table provided and performs
2230 all the necessary operations. The BFD output code must always be
2231 provided with an "owned" symbol: one which has come from another BFD,
2232 or one which has been created using `bfd_make_empty_symbol'. Here is an
2233 example showing the creation of a symbol table with only one element:
2235 #include "bfd.h"
2236 int main (void)
2237 {
2238 bfd *abfd;
2239 asymbol *ptrs[2];
2240 asymbol *new;
2242 abfd = bfd_openw ("foo","a.out-sunos-big");
2243 bfd_set_format (abfd, bfd_object);
2244 new = bfd_make_empty_symbol (abfd);
2245 new->name = "dummy_symbol";
2246 new->section = bfd_make_section_old_way (abfd, ".text");
2247 new->flags = BSF_GLOBAL;
2248 new->value = 0x12345;
2250 ptrs[0] = new;
2251 ptrs[1] = 0;
2253 bfd_set_symtab (abfd, ptrs, 1);
2254 bfd_close (abfd);
2255 return 0;
2256 }
2258 ./makesym
2259 nm foo
2260 00012345 A dummy_symbol
2262 Many formats cannot represent arbitrary symbol information; for
2263 instance, the `a.out' object format does not allow an arbitrary number
2264 of sections. A symbol pointing to a section which is not one of
2265 `.text', `.data' or `.bss' cannot be described.
2267 \x1f
2268 File: bfd.info, Node: Mini Symbols, Next: typedef asymbol, Prev: Writing Symbols, Up: Symbols
2270 2.7.3 Mini Symbols
2271 ------------------
2273 Mini symbols provide read-only access to the symbol table. They use
2274 less memory space, but require more time to access. They can be useful
2275 for tools like nm or objdump, which may have to handle symbol tables of
2276 extremely large executables.
2278 The `bfd_read_minisymbols' function will read the symbols into
2279 memory in an internal form. It will return a `void *' pointer to a
2280 block of memory, a symbol count, and the size of each symbol. The
2281 pointer is allocated using `malloc', and should be freed by the caller
2282 when it is no longer needed.
2284 The function `bfd_minisymbol_to_symbol' will take a pointer to a
2285 minisymbol, and a pointer to a structure returned by
2286 `bfd_make_empty_symbol', and return a `asymbol' structure. The return
2287 value may or may not be the same as the value from
2288 `bfd_make_empty_symbol' which was passed in.

2293 2.7.4 typedef asymbol
2294 ---------------------
2296 An `asymbol' has the form:
2299 typedef struct bfd_symbol
2300 {
2301 /* A pointer to the BFD which owns the symbol. This information
2302 is necessary so that a back end can work out what additional
2303 information (invisible to the application writer) is carried
2304 with the symbol.
2306 This field is *almost* redundant, since you can use section->owner
2307 instead, except that some symbols point to the global sections

2596 2.8 Archives
2597 ============
2599 *Description*
2600 An archive (or library) is just another BFD. It has a symbol table,
2601 although there's not much a user program will do with it.
2603 The big difference between an archive BFD and an ordinary BFD is
2604 that the archive doesn't have sections. Instead it has a chain of BFDs
2605 that are considered its contents. These BFDs can be manipulated like
2606 any other. The BFDs contained in an archive opened for reading will
2607 all be opened for reading. You may put either input or output BFDs
2608 into an archive opened for output; they will be handled correctly when
2609 the archive is closed.
2611 Use `bfd_openr_next_archived_file' to step through the contents of
2612 an archive opened for input. You don't have to read the entire archive
2613 if you don't want to! Read it until you find what you want.
2615 Archive contents of output BFDs are chained through the `next'
2616 pointer in a BFD. The first one is findable through the `archive_head'
2617 slot of the archive. Set it with `bfd_set_archive_head' (q.v.). A
2618 given BFD may be in only one open output archive at a time.
2620 As expected, the BFD archive code is more general than the archive
2621 code of any given environment. BFD archives may contain files of
2622 different formats (e.g., a.out and coff) and even different
2623 architectures. You may even place archives recursively into archives!
2625 This can cause unexpected confusion, since some archive formats are
2626 more expressive than others. For instance, Intel COFF archives can
2627 preserve long filenames; SunOS a.out archives cannot. If you move a
2628 file from the first to the second format and back again, the filename
2629 may be truncated. Likewise, different a.out environments have different
2630 conventions as to how they truncate filenames, whether they preserve
2631 directory names in filenames, etc. When interoperating with native
2632 tools, be sure your files are homogeneous.
2634 Beware: most of these formats do not react well to the presence of
2635 spaces in filenames. We do the best we can, but can't always handle
2636 this case due to restrictions in the format of archives. Many Unix
2637 utilities are braindead in regards to spaces and such in filenames
2638 anyway, so this shouldn't be much of a restriction.
2640 Archives are supported in BFD in `archive.c'.
2642 2.8.1 Archive functions

2650 (bfd *abfd, symindex previous, carsym **sym);
2651 *Description*
2652 Step through archive ABFD's symbol table (if it has one). Successively
2653 update SYM with the next symbol's information, returning that symbol's
2654 (internal) index into the symbol table.
2656 Supply `BFD_NO_MORE_SYMBOLS' as the PREVIOUS entry to get the first
2657 one; returns `BFD_NO_MORE_SYMBOLS' when you've already got the last one.
2659 A `carsym' is a canonical archive symbol. The only user-visible
2660 element is its name, a null-terminated string.
2662 2.8.1.2 `bfd_set_archive_head'

2672 ......................................
2674 *Synopsis*

2676 *Description*
2677 Provided a BFD, ARCHIVE, containing an archive and NULL, open an input
2678 BFD on the first contained element and returns that. Subsequent calls
2679 should pass the archive and the previous return value to return a
2680 created BFD to the next contained element. NULL is returned when there
2681 are no more.

2686 2.9 File formats
2687 ================
2689 A format is a BFD concept of high level file contents type. The formats
2690 supported by BFD are:
2692 * `bfd_object'
2693 The BFD may contain data, symbols, relocations and debug info.
2695 * `bfd_archive'
2696 The BFD contains other BFDs and an optional index.
2698 * `bfd_core'
2699 The BFD contains the result of an executable core dump.
2701 2.9.1 File format functions
2702 ---------------------------
2704 2.9.1.1 `bfd_check_format'
2705 ..........................
2707 *Synopsis*
2708 bfd_boolean bfd_check_format (bfd *abfd, bfd_format format);
2709 *Description*
2710 Verify if the file attached to the BFD ABFD is compatible with the
2711 format FORMAT (i.e., one of `bfd_object', `bfd_archive' or `bfd_core').
2713 If the BFD has been set to a specific target before the call, only
2714 the named target and format combination is checked. If the target has
2715 not been set, or has been set to `default', then all the known target
2716 backends is interrogated to determine a match. If the default target
2717 matches, it is used. If not, exactly one target must recognize the
2718 file, or an error results.
2720 The function returns `TRUE' on success, otherwise `FALSE' with one
2721 of the following error codes:
2723 * `bfd_error_invalid_operation' - if `format' is not one of
2724 `bfd_object', `bfd_archive' or `bfd_core'.
2726 * `bfd_error_system_call' - if an error occured during a read - even
2727 some file mismatches can cause bfd_error_system_calls.
2729 * `file_not_recognised' - none of the backends recognised the file
2730 format.
2732 * `bfd_error_file_ambiguously_recognized' - more than one backend
2733 recognised the file format.
2735 2.9.1.2 `bfd_check_format_matches'
2736 ..................................
2738 *Synopsis*
2739 bfd_boolean bfd_check_format_matches
2740 (bfd *abfd, bfd_format format, char ***matching);
2741 *Description*
2742 Like `bfd_check_format', except when it returns FALSE with `bfd_errno'
2743 set to `bfd_error_file_ambiguously_recognized'. In that case, if
2744 MATCHING is not NULL, it will be filled in with a NULL-terminated list
2745 of the names of the formats that matched, allocated with `malloc'.
2746 Then the user may choose a format and try again.
2748 When done with the list that MATCHING points to, the caller should
2749 free it.
2751 2.9.1.3 `bfd_set_format'
2752 ........................
2754 *Synopsis*
2755 bfd_boolean bfd_set_format (bfd *abfd, bfd_format format);
2756 *Description*
2757 This function sets the file format of the BFD ABFD to the format
2758 FORMAT. If the target set in the BFD does not support the format
2759 requested, the format is invalid, or the BFD is not open for writing,
2760 then an error occurs.
2762 2.9.1.4 `bfd_format_string'
2763 ...........................
2765 *Synopsis*
2766 const char *bfd_format_string (bfd_format format);
2767 *Description*
2768 Return a pointer to a const string `invalid', `object', `archive',
2769 `core', or `unknown', depending upon the value of FORMAT.

2774 2.10 Relocations
2775 ================
2777 BFD maintains relocations in much the same way it maintains symbols:
2778 they are left alone until required, then read in en-masse and
2779 translated into an internal form. A common routine
2780 `bfd_perform_relocation' acts upon the canonical form to do the fixup.
2782 Relocations are maintained on a per section basis, while symbols are
2783 maintained on a per BFD basis.
2785 All that a back end has to do to fit the BFD interface is to create
2786 a `struct reloc_cache_entry' for each relocation in a particular
2787 section, and fill in the right bits of the structures.

2849 }
2850 arelent;
2851 *Description*
2852 Here is a description of each of the fields within an `arelent':
2854 * `sym_ptr_ptr'
2855 The symbol table pointer points to a pointer to the symbol
2856 associated with the relocation request. It is the pointer into the
2857 table returned by the back end's `canonicalize_symtab' action. *Note
2858 Symbols::. The symbol is referenced through a pointer to a pointer so
2859 that tools like the linker can fix up all the symbols of the same name
2860 by modifying only one pointer. The relocation routine looks in the
2861 symbol and uses the base of the section the symbol is attached to and
2862 the value of the symbol as the initial relocation offset. If the symbol
2863 pointer is zero, then the section provided is looked up.
2865 * `address'
2866 The `address' field gives the offset in bytes from the base of the
2867 section data which owns the relocation record to the first byte of
2868 relocatable information. The actual data relocated will be relative to
2869 this point; for example, a relocation type which modifies the bottom
2870 two bytes of a four byte word would not touch the first byte pointed to
2871 in a big endian world.
2873 * `addend'
2874 The `addend' is a value provided by the back end to be added (!) to
2875 the relocation offset. Its interpretation is dependent upon the howto.
2876 For example, on the 68k the code:
2878 char foo[];
2879 main()
2880 {
2881 return foo[0x12345678];
2882 }
2884 Could be compiled into:
2886 linkw fp,#-4
2887 moveb @#12345678,d0
2888 extbl d0
2889 unlk fp
2890 rts
2892 This could create a reloc pointing to `foo', but leave the offset in
2893 the data, something like:
2895 RELOCATION RECORDS FOR [.text]:
2896 offset type value
2897 00000006 32 _foo
2899 00000000 4e56 fffc ; linkw fp,#-4
2900 00000004 1039 1234 5678 ; moveb @#12345678,d0
2901 0000000a 49c0 ; extbl d0
2902 0000000c 4e5e ; unlk fp
2903 0000000e 4e75 ; rts
2905 Using coff and an 88k, some instructions don't have enough space in
2906 them to represent the full address range, and pointers have to be
2907 loaded in two parts. So you'd get something like:
2909 or.u r13,r0,hi16(_foo+0x12345678)
2910 ld.b r2,r13,lo16(_foo+0x12345678)
2911 jmp r1
2913 This should create two relocs, both pointing to `_foo', and with
2914 0x12340000 in their addend field. The data would consist of:
2916 RELOCATION RECORDS FOR [.text]:
2917 offset type value
2918 00000002 HVRT16 _foo+0x12340000
2919 00000006 LVRT16 _foo+0x12340000
2921 00000000 5da05678 ; or.u r13,r0,0x5678
2922 00000004 1c4d5678 ; ld.b r2,r13,0x5678
2923 00000008 f400c001 ; jmp r1
2925 The relocation routine digs out the value from the data, adds it to
2926 the addend to get the original offset, and then adds the value of
2927 `_foo'. Note that all 32 bits have to be kept around somewhere, to cope
2928 with carry from bit 15 to bit 16.
2930 One further example is the sparc and the a.out format. The sparc has
2931 a similar problem to the 88k, in that some instructions don't have room
2932 for an entire offset, but on the sparc the parts are created in odd
2933 sized lumps. The designers of the a.out format chose to not use the
2934 data within the section for storing part of the offset; all the offset
2935 is kept within the reloc. Anything in the data should be ignored.
2937 save %sp,-112,%sp
2938 sethi %hi(_foo+0x12345678),%g2
2939 ldsb [%g2+%lo(_foo+0x12345678)],%i0
2940 ret
2941 restore
2943 Both relocs contain a pointer to `foo', and the offsets contain junk.
2945 RELOCATION RECORDS FOR [.text]:
2946 offset type value
2947 00000004 HI22 _foo+0x12345678
2948 00000008 LO10 _foo+0x12345678
2950 00000000 9de3bf90 ; save %sp,-112,%sp
2951 00000004 05000000 ; sethi %hi(_foo+0),%g2

2953 0000000c 81c7e008 ; ret
2954 00000010 81e80000 ; restore
2956 * `howto'
2957 The `howto' field can be imagined as a relocation instruction. It is
2958 a pointer to a structure which contains information on what to do with
2959 all of the other information in the reloc record and data section. A
2960 back end would normally have a relocation instruction set and turn
2961 relocations into pointers to the correct structure on input - but it
2962 would be possible to create each howto field on demand.

3171 char **error_message);
3172 *Description*
3173 If OUTPUT_BFD is supplied to this function, the generated image will be
3174 relocatable; the relocations are copied to the output file after they
3175 have been changed to reflect the new state of the world. There are two
3176 ways of reflecting the results of partial linkage in an output file: by
3177 modifying the output data in place, and by modifying the relocation
3178 record. Some native formats (e.g., basic a.out and basic coff) have no
3179 way of specifying an addend in the relocation type, so the addend has
3180 to go in the output data. This is no big deal since in these formats
3181 the output data slot will always be big enough for the addend. Complex
3182 reloc types with addends were invented to solve just this problem. The
3183 ERROR_MESSAGE argument is set to an error message if this return
3184 `bfd_reloc_dangerous'.

3196 *Description*
3197 This looks remarkably like `bfd_perform_relocation', except it does not
3198 expect that the section contents have been filled in. I.e., it's
3199 suitable for use when creating, rather than applying a relocation.
3201 For now, this function should be considered reserved for the
3202 assembler.

3207 2.10.2 The howto manager
3208 ------------------------
3210 When an application wants to create a relocation, but doesn't know what
3211 the target machine might call it, it can find out by using this bit of
3212 code.
3214 2.10.2.1 `bfd_reloc_code_type'
3215 ..............................
3217 *Description*
3218 The insides of a reloc code. The idea is that, eventually, there will
3219 be one enumerator for every type of relocation we ever do. Pass one of
3220 these values to `bfd_reloc_type_lookup', and it'll return a howto
3221 pointer.
3223 This does mean that the application must determine the correct
3224 enumerator value; you can't get a howto pointer from a random set of
3225 attributes.
3227 Here are the possible values for `enum bfd_reloc_code_real':
3229 -- : BFD_RELOC_64

3242 -- : BFD_RELOC_12_PCREL
3243 -- : BFD_RELOC_8_PCREL
3244 PC-relative relocations. Sometimes these are relative to the
3245 address of the relocation itself; sometimes they are relative to
3246 the start of the section containing the relocation. It depends on
3247 the specific target.
3249 The 24-bit relocation is used in some Intel 960 configurations.
3251 -- : BFD_RELOC_32_SECREL

3295 -- : BFD_RELOC_16_PCREL_S2
3296 -- : BFD_RELOC_23_PCREL_S2
3297 These PC-relative relocations are stored as word displacements -
3298 i.e., byte displacements shifted right two bits. The 30-bit word
3299 displacement (<<32_PCREL_S2>> - 32 bits, shifted 2) is used on the
3300 SPARC. (SPARC tools generally refer to this as <<WDISP30>>.) The
3301 signed 16-bit displacement is used on the MIPS, and the 23-bit
3302 displacement is used on the Alpha.
3304 -- : BFD_RELOC_HI22
3305 -- : BFD_RELOC_LO10
3306 High 22 bits and low 10 bits of 32-bit value, placed into lower
3307 bits of the target word. These are used on the SPARC.
3309 -- : BFD_RELOC_GPREL16
3310 -- : BFD_RELOC_GPREL32
3311 For systems that allocate a Global Pointer register, these are
3312 displacements off that register. These relocation types are
3313 handled specially, because the value the register will have is
3314 decided relatively late.

3417 SPU Relocations.
3419 -- : BFD_RELOC_ALPHA_GPDISP_HI16
3420 Alpha ECOFF and ELF relocations. Some of these treat the symbol or
3421 "addend" in some special way. For GPDISP_HI16 ("gpdisp")
3422 relocations, the symbol is ignored when writing; when reading, it
3423 will be the absolute section symbol. The addend is the
3424 displacement in bytes of the "lda" instruction from the "ldah"
3425 instruction (which is at the address of this reloc).
3427 -- : BFD_RELOC_ALPHA_GPDISP_LO16
3428 For GPDISP_LO16 ("ignore") relocations, the symbol is handled as
3429 with GPDISP_HI16 relocs. The addend is ignored when writing the
3430 relocations out, and is filled in with the file's GP value on
3431 reading, for convenience.
3433 -- : BFD_RELOC_ALPHA_GPDISP
3434 The ELF GPDISP relocation is exactly the same as the GPDISP_HI16
3435 relocation except that there is no accompanying GPDISP_LO16
3436 relocation.
3438 -- : BFD_RELOC_ALPHA_LITERAL
3439 -- : BFD_RELOC_ALPHA_ELF_LITERAL
3440 -- : BFD_RELOC_ALPHA_LITUSE
3441 The Alpha LITERAL/LITUSE relocs are produced by a symbol reference;
3442 the assembler turns it into a LDQ instruction to load the address
3443 of the symbol, and then fills in a register in the real
3444 instruction.
3446 The LITERAL reloc, at the LDQ instruction, refers to the .lita
3447 section symbol. The addend is ignored when writing, but is filled
3448 in with the file's GP value on reading, for convenience, as with
3449 the GPDISP_LO16 reloc.
3451 The ELF_LITERAL reloc is somewhere between 16_GOTOFF and
3452 GPDISP_LO16. It should refer to the symbol to be referenced, as
3453 with 16_GOTOFF, but it generates output not based on the position
3454 within the .got section, but relative to the GP value chosen for
3455 the file during the final link stage.
3457 The LITUSE reloc, on the instruction using the loaded address,
3458 gives information to the linker that it might be able to use to
3459 optimize away some literal section references. The symbol is
3460 ignored (read as the absolute section symbol), and the "addend"
3461 indicates the type of instruction using the register: 1 - "memory"
3462 fmt insn 2 - byte-manipulation (byte offset reg) 3 - jsr (target
3463 of branch)
3465 -- : BFD_RELOC_ALPHA_HINT
3466 The HINT relocation indicates a value that should be filled into
3467 the "hint" field of a jmp/jsr/ret instruction, for possible branch-
3468 prediction logic which may be provided on some processors.
3470 -- : BFD_RELOC_ALPHA_LINKAGE
3471 The LINKAGE relocation outputs a linkage pair in the object file,
3472 which is filled by the linker.
3474 -- : BFD_RELOC_ALPHA_CODEADDR
3475 The CODEADDR relocation outputs a STO_CA in the object file, which
3476 is filled by the linker.
3478 -- : BFD_RELOC_ALPHA_GPREL_HI16
3479 -- : BFD_RELOC_ALPHA_GPREL_LO16
3480 The GPREL_HI/LO relocations together form a 32-bit offset from the
3481 GP register.
3483 -- : BFD_RELOC_ALPHA_BRSGP
3484 Like BFD_RELOC_23_PCREL_S2, except that the source and target must
3485 share a common GP, and the target address is adjusted for
3486 STO_ALPHA_STD_GPLOAD.

3848 IBM 370/390 relocations
3850 -- : BFD_RELOC_CTOR
3851 The type of reloc used to build a constructor table - at the moment
3852 probably a 32 bit wide absolute relocation, but the target can
3853 choose. It generally does map to one of the other relocation
3854 types.

4829 These two relocations are used by the linker to determine which of
4830 the entries in a C++ virtual function table are actually used.
4831 When the -gc-sections option is given, the linker will zero out
4832 the entries that are not used, so that the code for those
4833 functions need not be included in the output.
4835 VTABLE_INHERIT is a zero-space relocation used to describe to the
4836 linker the inheritance tree of a C++ virtual function table. The
4837 relocation's symbol should be the parent class' vtable, and the
4838 relocation should be located at the child vtable.
4840 VTABLE_ENTRY is a zero-space relocation that describes the use of a
4841 virtual function table entry. The reloc's symbol should refer to
4842 the table of the class mentioned in the code. Off of that base,
4843 an offset describes the entry that is being used. For Rela hosts,
4844 this offset is stored in the reloc's addend. For Rel hosts, we
4845 are forced to put this offset in the reloc's section offset.

5445 2.12 Targets
5446 ============
5448 *Description*
5449 Each port of BFD to a different machine requires the creation of a
5450 target back end. All the back end provides to the root part of BFD is a
5451 structure containing pointers to functions which perform certain low
5452 level operations on files. BFD translates the applications's requests
5453 through a pointer into calls to the back end routines.
5455 When a file is opened with `bfd_openr', its format and target are
5456 unknown. BFD uses various mechanisms to determine how to interpret the
5457 file. The operations performed are:
5459 * Create a BFD by calling the internal routine `_bfd_new_bfd', then
5460 call `bfd_find_target' with the target string supplied to
5461 `bfd_openr' and the new BFD pointer.
5463 * If a null target string was provided to `bfd_find_target', look up
5464 the environment variable `GNUTARGET' and use that as the target
5465 string.
5467 * If the target string is still `NULL', or the target string is
5468 `default', then use the first item in the target vector as the
5469 target type, and set `target_defaulted' in the BFD to cause
5470 `bfd_check_format' to loop through all the targets. *Note
5471 bfd_target::. *Note Formats::.
5473 * Otherwise, inspect the elements in the target vector one by one,
5474 until a match on target name is found. When found, use it.
5476 * Otherwise return the error `bfd_error_invalid_target' to
5477 `bfd_openr'.
5479 * `bfd_openr' attempts to open the file using `bfd_open_file', and
5480 returns the BFD.
5481 Once the BFD has been opened and the target selected, the file
5482 format may be determined. This is done by calling `bfd_check_format' on
5483 the BFD with a suggested format. If `target_defaulted' has been set,
5484 each possible target type is tried to see if it recognizes the
5485 specified format. `bfd_check_format' returns `TRUE' when the caller
5486 guesses right.

5495 2.12.1 bfd_target
5496 -----------------
5498 *Description*
5499 This structure contains everything that BFD knows about a target. It
5500 includes things like its byte order, name, and which routines to call
5501 to do various operations.
5503 Every BFD points to a target structure with its `xvec' member.
5505 The macros below are used to dispatch to functions through the
5506 `bfd_target' vector. They are used in a number of macros further down
5507 in `bfd.h', and are also used when calling various routines by hand
5508 inside the BFD implementation. The ARGLIST argument must be
5509 parenthesized; it contains all the arguments to the called function.
5511 They make the documentation (more) unpleasant to read, so if someone
5512 wants to fix this and not break the above, please do.
5513 #define BFD_SEND(bfd, message, arglist) \
5514 ((*((bfd)->xvec->message)) arglist)
5516 #ifdef DEBUG_BFD_SEND
5517 #undef BFD_SEND
5518 #define BFD_SEND(bfd, message, arglist) \
5519 (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
5520 ((*((bfd)->xvec->message)) arglist) : \
5521 (bfd_assert (__FILE__,__LINE__), NULL))
5522 #endif
5523 For operations which index on the BFD format:
5524 #define BFD_SEND_FMT(bfd, message, arglist) \
5525 (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist)
5527 #ifdef DEBUG_BFD_SEND
5528 #undef BFD_SEND_FMT
5529 #define BFD_SEND_FMT(bfd, message, arglist) \
5530 (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
5531 (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist) : \
5532 (bfd_assert (__FILE__,__LINE__), NULL))
5533 #endif
5534 This is the structure which defines the type of BFD this is. The
5535 `xvec' member of the struct `bfd' itself points here. Each module that
5536 implements access to a different target under BFD, defines one of these.
5538 FIXME, these names should be rationalised with the names of the
5539 entry points which call them. Too bad we can't have one macro to define
5540 them both!

5925 bfd_boolean bfd_set_default_target (const char *name);
5926 *Description*
5927 Set the default target vector to use when recognizing a BFD. This
5928 takes the name of the target, which may be a BFD target name or a
5929 configuration triplet.

5932 ..........................
5934 *Synopsis*
5935 const bfd_target *bfd_find_target (const char *target_name, bfd *abfd);
5936 *Description*
5937 Return a pointer to the transfer vector for the object target named
5938 TARGET_NAME. If TARGET_NAME is `NULL', choose the one in the
5939 environment variable `GNUTARGET'; if that is null or not defined, then
5940 choose the first entry in the target list. Passing in the string
5941 "default" or setting the environment variable to "default" will cause
5942 the first entry in the target list to be returned, and
5943 "target_defaulted" will be set in the BFD if ABFD isn't `NULL'. This
5944 causes `bfd_check_format' to loop over all the targets to find the one
5945 that matches the file being read.

5952 *Description*
5953 Return a freshly malloced NULL-terminated vector of the names of all
5954 the valid BFD targets. Do not modify the names.

5963 *Description*
5964 Return a pointer to the first transfer vector in the list of transfer
5965 vectors maintained by BFD that produces a non-zero result when passed
5966 to the function SEARCH_FUNC. The parameter DATA is passed, unexamined,
5967 to the search function.

5972 2.13 Architectures
5973 ==================
5975 BFD keeps one atom in a BFD describing the architecture of the data
5976 attached to the BFD: a pointer to a `bfd_arch_info_type'.
5978 Pointers to structures can be requested independently of a BFD so
5979 that an architecture's information can be interrogated without access
5980 to an open BFD.
5982 The architecture information is provided by each architecture
5983 package. The set of default architectures is selected by the macro
5984 `SELECT_ARCHITECTURES'. This is normally set up in the
5985 `config/TARGET.mt' file of your choice. If the name is not defined,
5986 then all the architectures supported are included.
5988 When BFD starts up, all the architectures are called with an
5989 initialize method. It is up to the architecture back end to insert as
5990 many items into the list of architectures as it wants to; generally
5991 this would be one for each machine and one for the default case (an
5992 item with a machine field of 0).
5994 BFD's idea of an architecture is implemented in `archures.c'.

6004 architecture, containing, for example, 2 and 3 for Intel i960 KA and

6554 2.14 Opening and closing BFDs
6555 =============================
6557 2.14.1 Functions for opening and closing
6558 ----------------------------------------
6560 2.14.1.1 `bfd_fopen'
6561 ....................
6563 *Synopsis*
6564 bfd *bfd_fopen (const char *filename, const char *target,
6565 const char *mode, int fd);
6566 *Description*
6567 Open the file FILENAME with the target TARGET. Return a pointer to the
6568 created BFD. If FD is not -1, then `fdopen' is used to open the file;
6569 otherwise, `fopen' is used. MODE is passed directly to `fopen' or
6570 `fdopen'.
6572 Calls `bfd_find_target', so TARGET is interpreted as by that
6573 function.
6575 The new BFD is marked as cacheable iff FD is -1.
6577 If `NULL' is returned then an error has occured. Possible errors
6578 are `bfd_error_no_memory', `bfd_error_invalid_target' or `system_call'
6579 error.
6581 2.14.1.2 `bfd_openr'
6582 ....................
6584 *Synopsis*
6585 bfd *bfd_openr (const char *filename, const char *target);
6586 *Description*
6587 Open the file FILENAME (using `fopen') with the target TARGET. Return
6588 a pointer to the created BFD.
6590 Calls `bfd_find_target', so TARGET is interpreted as by that
6591 function.
6593 If `NULL' is returned then an error has occured. Possible errors
6594 are `bfd_error_no_memory', `bfd_error_invalid_target' or `system_call'
6595 error.
6597 2.14.1.3 `bfd_fdopenr'
6598 ......................
6600 *Synopsis*
6601 bfd *bfd_fdopenr (const char *filename, const char *target, int fd);
6602 *Description*
6603 `bfd_fdopenr' is to `bfd_fopenr' much like `fdopen' is to `fopen'. It
6604 opens a BFD on a file already described by the FD supplied.
6606 When the file is later `bfd_close'd, the file descriptor will be
6607 closed. If the caller desires that this file descriptor be cached by
6608 BFD (opened as needed, closed as needed to free descriptors for other
6609 opens), with the supplied FD used as an initial file descriptor (but
6610 subject to closure at any time), call bfd_set_cacheable(bfd, 1) on the
6611 returned BFD. The default is to assume no caching; the file descriptor
6612 will remain open until `bfd_close', and will not be affected by BFD
6613 operations on other files.
6615 Possible errors are `bfd_error_no_memory',
6616 `bfd_error_invalid_target' and `bfd_error_system_call'.
6618 2.14.1.4 `bfd_openstreamr'
6619 ..........................
6621 *Synopsis*
6622 bfd *bfd_openstreamr (const char *, const char *, void *);
6623 *Description*
6624 Open a BFD for read access on an existing stdio stream. When the BFD
6625 is passed to `bfd_close', the stream will be closed.
6627 2.14.1.5 `bfd_openr_iovec'
6628 ..........................
6630 *Synopsis*
6631 bfd *bfd_openr_iovec (const char *filename, const char *target,
6632 void *(*open) (struct bfd *nbfd,
6633 void *open_closure),
6634 void *open_closure,
6635 file_ptr (*pread) (struct bfd *nbfd,
6636 void *stream,
6637 void *buf,
6638 file_ptr nbytes,
6639 file_ptr offset),
6640 int (*close) (struct bfd *nbfd,
6641 void *stream),
6642 int (*stat) (struct bfd *abfd,
6643 void *stream,
6644 struct stat *sb));
6645 *Description*
6646 Create and return a BFD backed by a read-only STREAM. The STREAM is
6647 created using OPEN, accessed using PREAD and destroyed using CLOSE.
6649 Calls `bfd_find_target', so TARGET is interpreted as by that
6650 function.
6652 Calls OPEN (which can call `bfd_zalloc' and `bfd_get_filename') to
6653 obtain the read-only stream backing the BFD. OPEN either succeeds
6654 returning the non-`NULL' STREAM, or fails returning `NULL' (setting
6655 `bfd_error').
6657 Calls PREAD to request NBYTES of data from STREAM starting at OFFSET
6658 (e.g., via a call to `bfd_read'). PREAD either succeeds returning the
6659 number of bytes read (which can be less than NBYTES when end-of-file),
6660 or fails returning -1 (setting `bfd_error').
6662 Calls CLOSE when the BFD is later closed using `bfd_close'. CLOSE
6663 either succeeds returning 0, or fails returning -1 (setting
6664 `bfd_error').
6666 Calls STAT to fill in a stat structure for bfd_stat, bfd_get_size,
6667 and bfd_get_mtime calls. STAT returns 0 on success, or returns -1 on
6668 failure (setting `bfd_error').
6670 If `bfd_openr_iovec' returns `NULL' then an error has occurred.
6671 Possible errors are `bfd_error_no_memory', `bfd_error_invalid_target'
6672 and `bfd_error_system_call'.
6674 2.14.1.6 `bfd_openw'
6675 ....................
6677 *Synopsis*
6678 bfd *bfd_openw (const char *filename, const char *target);
6679 *Description*
6680 Create a BFD, associated with file FILENAME, using the file format
6681 TARGET, and return a pointer to it.
6683 Possible errors are `bfd_error_system_call', `bfd_error_no_memory',
6684 `bfd_error_invalid_target'.
6686 2.14.1.7 `bfd_close'
6687 ....................
6689 *Synopsis*
6690 bfd_boolean bfd_close (bfd *abfd);
6691 *Description*
6692 Close a BFD. If the BFD was open for writing, then pending operations
6693 are completed and the file written out and closed. If the created file
6694 is executable, then `chmod' is called to mark it as such.
6696 All memory attached to the BFD is released.
6698 The file descriptor associated with the BFD is closed (even if it
6699 was passed in to BFD by `bfd_fdopenr').
6701 *Returns*
6702 `TRUE' is returned if all is ok, otherwise `FALSE'.
6704 2.14.1.8 `bfd_close_all_done'
6705 .............................
6707 *Synopsis*
6708 bfd_boolean bfd_close_all_done (bfd *);
6709 *Description*
6710 Close a BFD. Differs from `bfd_close' since it does not complete any
6711 pending operations. This routine would be used if the application had
6712 just used BFD for swapping and didn't want to use any of the writing
6713 code.
6715 If the created file is executable, then `chmod' is called to mark it
6716 as such.
6718 All memory attached to the BFD is released.
6720 *Returns*
6721 `TRUE' is returned if all is ok, otherwise `FALSE'.
6723 2.14.1.9 `bfd_create'
6724 .....................
6726 *Synopsis*
6727 bfd *bfd_create (const char *filename, bfd *templ);
6728 *Description*
6729 Create a new BFD in the manner of `bfd_openw', but without opening a
6730 file. The new BFD takes the target from the target used by TEMPLATE.
6731 The format is always set to `bfd_object'.
6733 2.14.1.10 `bfd_make_writable'
6734 .............................
6736 *Synopsis*
6737 bfd_boolean bfd_make_writable (bfd *abfd);
6738 *Description*
6739 Takes a BFD as created by `bfd_create' and converts it into one like as
6740 returned by `bfd_openw'. It does this by converting the BFD to
6741 BFD_IN_MEMORY. It's assumed that you will call `bfd_make_readable' on
6742 this bfd later.
6744 *Returns*
6745 `TRUE' is returned if all is ok, otherwise `FALSE'.
6747 2.14.1.11 `bfd_make_readable'
6748 .............................
6750 *Synopsis*
6751 bfd_boolean bfd_make_readable (bfd *abfd);
6752 *Description*
6753 Takes a BFD as created by `bfd_create' and `bfd_make_writable' and
6754 converts it into one like as returned by `bfd_openr'. It does this by
6755 writing the contents out to the memory buffer, then reversing the
6756 direction.
6758 *Returns*
6759 `TRUE' is returned if all is ok, otherwise `FALSE'.
6761 2.14.1.12 `bfd_alloc'
6762 .....................
6764 *Synopsis*
6765 void *bfd_alloc (bfd *abfd, bfd_size_type wanted);
6766 *Description*
6767 Allocate a block of WANTED bytes of memory attached to `abfd' and
6768 return a pointer to it.
6770 2.14.1.13 `bfd_alloc2'
6771 ......................
6773 *Synopsis*
6774 void *bfd_alloc2 (bfd *abfd, bfd_size_type nmemb, bfd_size_type size);
6775 *Description*
6776 Allocate a block of NMEMB elements of SIZE bytes each of memory
6777 attached to `abfd' and return a pointer to it.
6779 2.14.1.14 `bfd_zalloc'
6780 ......................
6782 *Synopsis*
6783 void *bfd_zalloc (bfd *abfd, bfd_size_type wanted);
6784 *Description*
6785 Allocate a block of WANTED bytes of zeroed memory attached to `abfd'
6786 and return a pointer to it.
6788 2.14.1.15 `bfd_zalloc2'
6789 .......................
6791 *Synopsis*
6792 void *bfd_zalloc2 (bfd *abfd, bfd_size_type nmemb, bfd_size_type size);
6793 *Description*
6794 Allocate a block of NMEMB elements of SIZE bytes each of zeroed memory
6795 attached to `abfd' and return a pointer to it.
6797 2.14.1.16 `bfd_calc_gnu_debuglink_crc32'
6798 ........................................
6800 *Synopsis*
6801 unsigned long bfd_calc_gnu_debuglink_crc32
6802 (unsigned long crc, const unsigned char *buf, bfd_size_type len);
6803 *Description*
6804 Computes a CRC value as used in the .gnu_debuglink section. Advances
6805 the previously computed CRC value by computing and adding in the crc32
6806 for LEN bytes of BUF.
6808 *Returns*
6809 Return the updated CRC32 value.
6811 2.14.1.17 `get_debug_link_info'
6812 ...............................
6814 *Synopsis*
6815 char *get_debug_link_info (bfd *abfd, unsigned long *crc32_out);
6816 *Description*
6817 fetch the filename and CRC32 value for any separate debuginfo
6818 associated with ABFD. Return NULL if no such info found, otherwise
6819 return filename and update CRC32_OUT.
6821 2.14.1.18 `separate_debug_file_exists'
6822 ......................................
6824 *Synopsis*
6825 bfd_boolean separate_debug_file_exists
6826 (char *name, unsigned long crc32);
6827 *Description*
6828 Checks to see if NAME is a file and if its contents match CRC32.
6830 2.14.1.19 `find_separate_debug_file'
6831 ....................................
6833 *Synopsis*
6834 char *find_separate_debug_file (bfd *abfd);
6835 *Description*
6836 Searches ABFD for a reference to separate debugging information, scans
6837 various locations in the filesystem, including the file tree rooted at
6838 DEBUG_FILE_DIRECTORY, and returns a filename of such debugging
6839 information if the file is found and has matching CRC32. Returns NULL
6840 if no reference to debugging file exists, or file cannot be found.
6842 2.14.1.20 `bfd_follow_gnu_debuglink'
6843 ....................................
6845 *Synopsis*
6846 char *bfd_follow_gnu_debuglink (bfd *abfd, const char *dir);
6847 *Description*
6848 Takes a BFD and searches it for a .gnu_debuglink section. If this
6849 section is found, it examines the section for the name and checksum of
6850 a '.debug' file containing auxiliary debugging information. It then
6851 searches the filesystem for this .debug file in some standard
6852 locations, including the directory tree rooted at DIR, and if found
6853 returns the full filename.
6855 If DIR is NULL, it will search a default path configured into libbfd
6856 at build time. [XXX this feature is not currently implemented].
6858 *Returns*
6859 `NULL' on any errors or failure to locate the .debug file, otherwise a
6860 pointer to a heap-allocated string containing the filename. The caller
6861 is responsible for freeing this string.
6863 2.14.1.21 `bfd_create_gnu_debuglink_section'
6864 ............................................
6866 *Synopsis*
6867 struct bfd_section *bfd_create_gnu_debuglink_section
6868 (bfd *abfd, const char *filename);
6869 *Description*
6870 Takes a BFD and adds a .gnu_debuglink section to it. The section is
6871 sized to be big enough to contain a link to the specified FILENAME.
6873 *Returns*
6874 A pointer to the new section is returned if all is ok. Otherwise
6875 `NULL' is returned and bfd_error is set.
6877 2.14.1.22 `bfd_fill_in_gnu_debuglink_section'
6878 .............................................
6880 *Synopsis*
6881 bfd_boolean bfd_fill_in_gnu_debuglink_section
6882 (bfd *abfd, struct bfd_section *sect, const char *filename);
6883 *Description*
6884 Takes a BFD and containing a .gnu_debuglink section SECT and fills in
6885 the contents of the section to contain a link to the specified
6886 FILENAME. The filename should be relative to the current directory.
6888 *Returns*
6889 `TRUE' is returned if all is ok. Otherwise `FALSE' is returned and
6890 bfd_error is set.

6895 2.15 Implementation details
6896 ===========================
6898 2.15.1 Internal functions
6899 -------------------------
6901 *Description*
6902 These routines are used within BFD. They are not intended for export,
6903 but are documented here for completeness.
6905 2.15.1.1 `bfd_write_bigendian_4byte_int'
6906 ........................................
6908 *Synopsis*
6909 bfd_boolean bfd_write_bigendian_4byte_int (bfd *, unsigned int);
6910 *Description*
6911 Write a 4 byte integer I to the output BFD ABFD, in big endian order
6912 regardless of what else is going on. This is useful in archives.
6914 2.15.1.2 `bfd_put_size'
6915 .......................
6917 2.15.1.3 `bfd_get_size'
6918 .......................
6920 *Description*
6921 These macros as used for reading and writing raw data in sections; each
6922 access (except for bytes) is vectored through the target format of the
6923 BFD and mangled accordingly. The mangling performs any necessary endian
6924 translations and removes alignment restrictions. Note that types
6925 accepted and returned by these macros are identical so they can be
6926 swapped around in macros--for example, `libaout.h' defines `GET_WORD'
6927 to either `bfd_get_32' or `bfd_get_64'.
6929 In the put routines, VAL must be a `bfd_vma'. If we are on a system
6930 without prototypes, the caller is responsible for making sure that is
6931 true, with a cast if necessary. We don't cast them in the macro
6932 definitions because that would prevent `lint' or `gcc -Wall' from
6933 detecting sins such as passing a pointer. To detect calling these with
6934 less than a `bfd_vma', use `gcc -Wconversion' on a host with 64 bit
6935 `bfd_vma''s.

6992 *Description*
6993 These macros have the same function as their `bfd_get_x' brethren,
6994 except that they are used for removing information for the header
6995 records of object files. Believe it or not, some object files keep
6996 their header records in big endian order and their data in little

7072 application to open as many BFDs as it wants without regard to the
7073 underlying operating system's file descriptor limit (often as low as 20
7074 open files). The module in `cache.c' maintains a least recently used
7075 list of `BFD_CACHE_MAX_OPEN' files, and exports the name
7076 `bfd_cache_lookup', which runs around and makes sure that the required
7077 BFD is open. If not, then it chooses a file to close, closes it and
7078 opens the one wanted, returning its file handle.

7132 2.17 Linker Functions
7133 =====================
7135 The linker uses three special entry points in the BFD target vector.
7136 It is not necessary to write special routines for these entry points
7137 when creating a new BFD back end, since generic versions are provided.
7138 However, writing them can speed up linking and make it use
7139 significantly less runtime memory.
7141 The first routine creates a hash table used by the other routines.
7142 The second routine adds the symbols from an object file to the hash
7143 table. The third routine takes all the object files and links them
7144 together to create the output file. These routines are designed so
7145 that the linker proper does not need to know anything about the symbols
7146 in the object files that it is linking. The linker merely arranges the
7147 sections as directed by the linker script and lets BFD handle the
7148 details of symbols and relocs.
7150 The second routine and third routines are passed a pointer to a
7151 `struct bfd_link_info' structure (defined in `bfdlink.h') which holds
7152 information relevant to the link, including the linker hash table
7153 (which was created by the first routine) and a set of callback
7154 functions to the linker proper.
7156 The generic linker routines are in `linker.c', and use the header
7157 file `genlink.h'. As of this writing, the only back ends which have
7158 implemented versions of these routines are a.out (in `aoutx.h') and
7159 ECOFF (in `ecoff.c'). The a.out routines are used as examples
7160 throughout this section.

7171 2.17.1 Creating a linker hash table
7172 -----------------------------------
7174 The linker routines must create a hash table, which must be derived
7175 from `struct bfd_link_hash_table' described in `bfdlink.c'. *Note Hash
7176 Tables::, for information on how to create a derived hash table. This
7177 entry point is called using the target vector of the linker output file.
7179 The `_bfd_link_hash_table_create' entry point must allocate and
7180 initialize an instance of the desired hash table. If the back end does
7181 not require any additional information to be stored with the entries in
7182 the hash table, the entry point may simply create a `struct
7183 bfd_link_hash_table'. Most likely, however, some additional
7184 information will be needed.
7186 For example, with each entry in the hash table the a.out linker
7187 keeps the index the symbol has in the final output file (this index
7188 number is used so that when doing a relocatable link the symbol index
7189 used in the output file can be quickly filled in when copying over a
7190 reloc). The a.out linker code defines the required structures and
7191 functions for a hash table derived from `struct bfd_link_hash_table'.
7192 The a.out linker hash table is created by the function
7193 `NAME(aout,link_hash_table_create)'; it simply allocates space for the
7194 hash table, initializes it, and returns a pointer to it.
7196 When writing the linker routines for a new back end, you will
7197 generally not know exactly which fields will be required until you have
7198 finished. You should simply create a new hash table which defines no
7199 additional fields, and then simply add fields as they become necessary.

7204 2.17.2 Adding symbols to the hash table
7205 ---------------------------------------
7207 The linker proper will call the `_bfd_link_add_symbols' entry point for
7208 each object file or archive which is to be linked (typically these are
7209 the files named on the command line, but some may also come from the
7210 linker script). The entry point is responsible for examining the file.
7211 For an object file, BFD must add any relevant symbol information to
7212 the hash table. For an archive, BFD must determine which elements of
7213 the archive should be used and adding them to the link.
7215 The a.out version of this entry point is
7216 `NAME(aout,link_add_symbols)'.

7227 2.17.2.1 Differing file formats
7228 ...............................
7230 Normally all the files involved in a link will be of the same format,
7231 but it is also possible to link together different format object files,
7232 and the back end must support that. The `_bfd_link_add_symbols' entry
7233 point is called via the target vector of the file to be added. This
7234 has an important consequence: the function may not assume that the hash
7235 table is the type created by the corresponding
7236 `_bfd_link_hash_table_create' vector. All the `_bfd_link_add_symbols'
7237 function can assume about the hash table is that it is derived from
7238 `struct bfd_link_hash_table'.
7240 Sometimes the `_bfd_link_add_symbols' function must store some
7241 information in the hash table entry to be used by the `_bfd_final_link'
7242 function. In such a case the output bfd xvec must be checked to make
7243 sure that the hash table was created by an object file of the same
7244 format.
7246 The `_bfd_final_link' routine must be prepared to handle a hash
7247 entry without any extra information added by the
7248 `_bfd_link_add_symbols' function. A hash entry without extra
7249 information will also occur when the linker script directs the linker
7250 to create a symbol. Note that, regardless of how a hash table entry is
7251 added, all the fields will be initialized to some sort of null value by
7252 the hash table entry initialization function.
7254 See `ecoff_link_add_externals' for an example of how to check the
7255 output bfd before saving information (in this case, the ECOFF external
7256 symbol debugging information) in a hash table entry.

7261 2.17.2.2 Adding symbols from an object file
7262 ...........................................
7264 When the `_bfd_link_add_symbols' routine is passed an object file, it
7265 must add all externally visible symbols in that object file to the hash
7266 table. The actual work of adding the symbol to the hash table is
7267 normally handled by the function `_bfd_generic_link_add_one_symbol'.
7268 The `_bfd_link_add_symbols' routine is responsible for reading all the
7269 symbols from the object file and passing the correct information to
7270 `_bfd_generic_link_add_one_symbol'.
7272 The `_bfd_link_add_symbols' routine should not use
7273 `bfd_canonicalize_symtab' to read the symbols. The point of providing
7274 this routine is to avoid the overhead of converting the symbols into
7275 generic `asymbol' structures.
7277 `_bfd_generic_link_add_one_symbol' handles the details of combining
7278 common symbols, warning about multiple definitions, and so forth. It
7279 takes arguments which describe the symbol to add, notably symbol flags,
7280 a section, and an offset. The symbol flags include such things as
7281 `BSF_WEAK' or `BSF_INDIRECT'. The section is a section in the object
7282 file, or something like `bfd_und_section_ptr' for an undefined symbol
7283 or `bfd_com_section_ptr' for a common symbol.
7285 If the `_bfd_final_link' routine is also going to need to read the
7286 symbol information, the `_bfd_link_add_symbols' routine should save it
7287 somewhere attached to the object file BFD. However, the information
7288 should only be saved if the `keep_memory' field of the `info' argument
7289 is TRUE, so that the `-no-keep-memory' linker switch is effective.
7291 The a.out function which adds symbols from an object file is
7292 `aout_link_add_object_symbols', and most of the interesting work is in
7293 `aout_link_add_symbols'. The latter saves pointers to the hash tables
7294 entries created by `_bfd_generic_link_add_one_symbol' indexed by symbol
7295 number, so that the `_bfd_final_link' routine does not have to call the
7296 hash table lookup routine to locate the entry.

7299 File: bfd.info, Node: Adding symbols from an archive, Prev: Adding symbols from an object file, Up: Adding Symbols to the Hash Table
7301 2.17.2.3 Adding symbols from an archive
7302 .......................................
7304 When the `_bfd_link_add_symbols' routine is passed an archive, it must
7305 look through the symbols defined by the archive and decide which
7306 elements of the archive should be included in the link. For each such
7307 element it must call the `add_archive_element' linker callback, and it
7308 must add the symbols from the object file to the linker hash table.
7310 In most cases the work of looking through the symbols in the archive
7311 should be done by the `_bfd_generic_link_add_archive_symbols' function.
7312 This function builds a hash table from the archive symbol table and
7313 looks through the list of undefined symbols to see which elements
7314 should be included. `_bfd_generic_link_add_archive_symbols' is passed
7315 a function to call to make the final decision about adding an archive
7316 element to the link and to do the actual work of adding the symbols to
7317 the linker hash table.
7319 The function passed to `_bfd_generic_link_add_archive_symbols' must
7320 read the symbols of the archive element and decide whether the archive
7321 element should be included in the link. If the element is to be
7322 included, the `add_archive_element' linker callback routine must be
7323 called with the element as an argument, and the elements symbols must
7324 be added to the linker hash table just as though the element had itself
7325 been passed to the `_bfd_link_add_symbols' function.
7327 When the a.out `_bfd_link_add_symbols' function receives an archive,
7328 it calls `_bfd_generic_link_add_archive_symbols' passing
7329 `aout_link_check_archive_element' as the function argument.
7330 `aout_link_check_archive_element' calls `aout_link_check_ar_symbols'.
7331 If the latter decides to add the element (an element is only added if
7332 it provides a real, non-common, definition for a previously undefined
7333 or common symbol) it calls the `add_archive_element' callback and then
7334 `aout_link_check_archive_element' calls `aout_link_add_symbols' to
7335 actually add the symbols to the linker hash table.
7337 The ECOFF back end is unusual in that it does not normally call
7338 `_bfd_generic_link_add_archive_symbols', because ECOFF archives already
7339 contain a hash table of symbols. The ECOFF back end searches the
7340 archive itself to avoid the overhead of creating a new hash table.

7345 2.17.3 Performing the final link
7346 --------------------------------
7348 When all the input files have been processed, the linker calls the
7349 `_bfd_final_link' entry point of the output BFD. This routine is
7350 responsible for producing the final output file, which has several
7351 aspects. It must relocate the contents of the input sections and copy
7352 the data into the output sections. It must build an output symbol
7353 table including any local symbols from the input files and the global
7354 symbols from the hash table. When producing relocatable output, it must
7355 modify the input relocs and write them into the output file. There may
7356 also be object format dependent work to be done.
7358 The linker will also call the `write_object_contents' entry point
7359 when the BFD is closed. The two entry points must work together in
7360 order to produce the correct output file.
7362 The details of how this works are inevitably dependent upon the
7363 specific object file format. The a.out `_bfd_final_link' routine is
7364 `NAME(aout,final_link)'.

7378 Before the linker calls the `_bfd_final_link' entry point, it sets up
7379 some data structures for the function to use.
7381 The `input_bfds' field of the `bfd_link_info' structure will point
7382 to a list of all the input files included in the link. These files are
7383 linked through the `link_next' field of the `bfd' structure.
7385 Each section in the output file will have a list of `link_order'
7386 structures attached to the `map_head.link_order' field (the
7387 `link_order' structure is defined in `bfdlink.h'). These structures
7388 describe how to create the contents of the output section in terms of
7389 the contents of various input sections, fill constants, and,
7390 eventually, other types of information. They also describe relocs that
7391 must be created by the BFD backend, but do not correspond to any input
7392 file; this is used to support -Ur, which builds constructors while
7393 generating a relocatable object file.

7398 2.17.3.2 Relocating the section contents
7399 ........................................
7401 The `_bfd_final_link' function should look through the `link_order'
7402 structures attached to each section of the output file. Each
7403 `link_order' structure should either be handled specially, or it should
7404 be passed to the function `_bfd_default_link_order' which will do the
7405 right thing (`_bfd_default_link_order' is defined in `linker.c').
7407 For efficiency, a `link_order' of type `bfd_indirect_link_order'
7408 whose associated section belongs to a BFD of the same format as the
7409 output BFD must be handled specially. This type of `link_order'
7410 describes part of an output section in terms of a section belonging to
7411 one of the input files. The `_bfd_final_link' function should read the
7412 contents of the section and any associated relocs, apply the relocs to
7413 the section contents, and write out the modified section contents. If
7414 performing a relocatable link, the relocs themselves must also be
7415 modified and written out.
7417 The functions `_bfd_relocate_contents' and
7418 `_bfd_final_link_relocate' provide some general support for performing
7419 the actual relocations, notably overflow checking. Their arguments
7420 include information about the symbol the relocation is against and a
7421 `reloc_howto_type' argument which describes the relocation to perform.
7422 These functions are defined in `reloc.c'.
7424 The a.out function which handles reading, relocating, and writing
7425 section contents is `aout_link_input_section'. The actual relocation
7426 is done in `aout_link_input_section_std' and
7427 `aout_link_input_section_ext'.

7433 .................................
7435 The `_bfd_final_link' function must gather all the symbols in the input
7436 files and write them out. It must also write out all the symbols in
7437 the global hash table. This must be controlled by the `strip' and
7438 `discard' fields of the `bfd_link_info' structure.
7440 The local symbols of the input files will not have been entered into
7441 the linker hash table. The `_bfd_final_link' routine must consider
7442 each input file and include the symbols in the output file. It may be
7443 convenient to do this when looking through the `link_order' structures,
7444 or it may be done by stepping through the `input_bfds' list.
7446 The `_bfd_final_link' routine must also traverse the global hash
7447 table to gather all the externally visible symbols. It is possible
7448 that most of the externally visible symbols may be written out when
7449 considering the symbols of each input file, but it is still necessary
7450 to traverse the hash table since the linker script may have defined
7451 some symbols that are not in any of the input files.
7453 The `strip' field of the `bfd_link_info' structure controls which
7454 symbols are written out. The possible values are listed in
7455 `bfdlink.h'. If the value is `strip_some', then the `keep_hash' field
7456 of the `bfd_link_info' structure is a hash table of symbols to keep;
7457 each symbol should be looked up in this hash table, and only symbols
7458 which are present should be included in the output file.
7460 If the `strip' field of the `bfd_link_info' structure permits local
7461 symbols to be written out, the `discard' field is used to further
7462 controls which local symbols are included in the output file. If the
7463 value is `discard_l', then all local symbols which begin with a certain
7464 prefix are discarded; this is controlled by the
7465 `bfd_is_local_label_name' entry point.
7467 The a.out backend handles symbols by calling
7468 `aout_link_write_symbols' on each input BFD and then traversing the
7469 global hash table with the function `aout_link_write_other_symbol'. It
7470 builds a string table while writing out the symbols, which is written
7471 to the output file at the end of `NAME(aout,final_link)'.

7499 2.18 Hash Tables
7500 ================
7502 BFD provides a simple set of hash table functions. Routines are
7503 provided to initialize a hash table, to free a hash table, to look up a
7504 string in a hash table and optionally create an entry for it, and to
7505 traverse a hash table. There is currently no routine to delete an
7506 string from a hash table.
7508 The basic hash table does not permit any data to be stored with a
7509 string. However, a hash table is designed to present a base class from
7510 which other types of hash tables may be derived. These derived types
7511 may store additional information with the string. Hash tables were
7512 implemented in this way, rather than simply providing a data pointer in
7513 a hash table entry, because they were designed for use by the linker
7514 back ends. The linker may create thousands of hash table entries, and
7515 the overhead of allocating private data and storing and following
7516 pointers becomes noticeable.
7518 The basic hash table code is in `hash.c'.

7530 2.18.1 Creating and freeing a hash table
7531 ----------------------------------------
7533 To create a hash table, create an instance of a `struct bfd_hash_table'
7534 (defined in `bfd.h') and call `bfd_hash_table_init' (if you know
7535 approximately how many entries you will need, the function
7536 `bfd_hash_table_init_n', which takes a SIZE argument, may be used).
7537 `bfd_hash_table_init' returns `FALSE' if some sort of error occurs.
7539 The function `bfd_hash_table_init' take as an argument a function to
7540 use to create new entries. For a basic hash table, use the function
7541 `bfd_hash_newfunc'. *Note Deriving a New Hash Table Type::, for why
7542 you would want to use a different value for this argument.
7544 `bfd_hash_table_init' will create an objalloc which will be used to
7545 allocate new entries. You may allocate memory on this objalloc using
7546 `bfd_hash_allocate'.
7548 Use `bfd_hash_table_free' to free up all the memory that has been
7549 allocated for a hash table. This will not free up the `struct
7550 bfd_hash_table' itself, which you must provide.
7552 Use `bfd_hash_set_default_size' to set the default size of hash
7553 table to use.

7559 --------------------------------------
7561 The function `bfd_hash_lookup' is used both to look up a string in the
7562 hash table and to create a new entry.
7564 If the CREATE argument is `FALSE', `bfd_hash_lookup' will look up a
7565 string. If the string is found, it will returns a pointer to a `struct
7566 bfd_hash_entry'. If the string is not found in the table
7567 `bfd_hash_lookup' will return `NULL'. You should not modify any of the
7568 fields in the returns `struct bfd_hash_entry'.
7570 If the CREATE argument is `TRUE', the string will be entered into
7571 the hash table if it is not already there. Either way a pointer to a
7572 `struct bfd_hash_entry' will be returned, either to the existing
7573 structure or to a newly created one. In this case, a `NULL' return
7574 means that an error occurred.
7576 If the CREATE argument is `TRUE', and a new entry is created, the
7577 COPY argument is used to decide whether to copy the string onto the
7578 hash table objalloc or not. If COPY is passed as `FALSE', you must be
7579 careful not to deallocate or modify the string as long as the hash table
7580 exists.

7585 2.18.3 Traversing a hash table
7586 ------------------------------
7588 The function `bfd_hash_traverse' may be used to traverse a hash table,
7589 calling a function on each element. The traversal is done in a random
7590 order.
7592 `bfd_hash_traverse' takes as arguments a function and a generic
7593 `void *' pointer. The function is called with a hash table entry (a
7594 `struct bfd_hash_entry *') and the generic pointer passed to
7595 `bfd_hash_traverse'. The function must return a `boolean' value, which
7596 indicates whether to continue traversing the hash table. If the
7597 function returns `FALSE', `bfd_hash_traverse' will stop the traversal
7598 and return immediately.

7603 2.18.4 Deriving a new hash table type
7604 -------------------------------------
7606 Many uses of hash tables want to store additional information which
7607 each entry in the hash table. Some also find it convenient to store
7608 additional information with the hash table itself. This may be done
7609 using a derived hash table.
7611 Since C is not an object oriented language, creating a derived hash
7612 table requires sticking together some boilerplate routines with a few
7613 differences specific to the type of hash table you want to create.
7615 An example of a derived hash table is the linker hash table. The
7616 structures for this are defined in `bfdlink.h'. The functions are in
7617 `linker.c'.
7619 You may also derive a hash table from an already derived hash table.
7620 For example, the a.out linker backend code uses a hash table derived
7621 from the linker hash table.

7632 2.18.4.1 Define the derived structures
7633 ......................................
7635 You must define a structure for an entry in the hash table, and a
7636 structure for the hash table itself.
7638 The first field in the structure for an entry in the hash table must
7639 be of the type used for an entry in the hash table you are deriving
7640 from. If you are deriving from a basic hash table this is `struct
7641 bfd_hash_entry', which is defined in `bfd.h'. The first field in the
7642 structure for the hash table itself must be of the type of the hash
7643 table you are deriving from itself. If you are deriving from a basic
7644 hash table, this is `struct bfd_hash_table'.
7646 For example, the linker hash table defines `struct
7647 bfd_link_hash_entry' (in `bfdlink.h'). The first field, `root', is of
7648 type `struct bfd_hash_entry'. Similarly, the first field in `struct
7649 bfd_link_hash_table', `table', is of type `struct bfd_hash_table'.

7654 2.18.4.2 Write the derived creation routine
7655 ...........................................
7657 You must write a routine which will create and initialize an entry in
7658 the hash table. This routine is passed as the function argument to
7659 `bfd_hash_table_init'.
7661 In order to permit other hash tables to be derived from the hash
7662 table you are creating, this routine must be written in a standard way.
7664 The first argument to the creation routine is a pointer to a hash
7665 table entry. This may be `NULL', in which case the routine should
7666 allocate the right amount of space. Otherwise the space has already
7667 been allocated by a hash table type derived from this one.
7669 After allocating space, the creation routine must call the creation
7670 routine of the hash table type it is derived from, passing in a pointer
7671 to the space it just allocated. This will initialize any fields used
7672 by the base hash table.
7674 Finally the creation routine must initialize any local fields for
7675 the new hash table type.
7677 Here is a boilerplate example of a creation routine. FUNCTION_NAME
7678 is the name of the routine. ENTRY_TYPE is the type of an entry in the
7679 hash table you are creating. BASE_NEWFUNC is the name of the creation
7680 routine of the hash table type your hash table is derived from.
7682 struct bfd_hash_entry *
7683 FUNCTION_NAME (struct bfd_hash_entry *entry,
7684 struct bfd_hash_table *table,
7685 const char *string)
7686 {
7687 struct ENTRY_TYPE *ret = (ENTRY_TYPE *) entry;
7689 /* Allocate the structure if it has not already been allocated by a
7690 derived class. */
7691 if (ret == NULL)
7692 {
7693 ret = bfd_hash_allocate (table, sizeof (* ret));
7694 if (ret == NULL)
7695 return NULL;
7696 }
7698 /* Call the allocation method of the base class. */
7699 ret = ((ENTRY_TYPE *)
7700 BASE_NEWFUNC ((struct bfd_hash_entry *) ret, table, string));
7702 /* Initialize the local fields here. */
7704 return (struct bfd_hash_entry *) ret;
7705 }
7706 *Description*
7707 The creation routine for the linker hash table, which is in `linker.c',
7708 looks just like this example. FUNCTION_NAME is
7709 `_bfd_link_hash_newfunc'. ENTRY_TYPE is `struct bfd_link_hash_entry'.
7710 BASE_NEWFUNC is `bfd_hash_newfunc', the creation routine for a basic
7711 hash table.
7713 `_bfd_link_hash_newfunc' also initializes the local fields in a
7714 linker hash table entry: `type', `written' and `next'.

7719 2.18.4.3 Write other derived routines
7720 .....................................
7722 You will want to write other routines for your new hash table, as well.
7724 You will want an initialization routine which calls the
7725 initialization routine of the hash table you are deriving from and
7726 initializes any other local fields. For the linker hash table, this is
7727 `_bfd_link_hash_table_init' in `linker.c'.
7729 You will want a lookup routine which calls the lookup routine of the
7730 hash table you are deriving from and casts the result. The linker hash
7731 table uses `bfd_link_hash_lookup' in `linker.c' (this actually takes an
7732 additional argument which it uses to decide how to return the looked up
7733 value).
7735 You may want a traversal routine. This should just call the
7736 traversal routine of the hash table you are deriving from with
7737 appropriate casts. The linker hash table uses `bfd_link_hash_traverse'
7738 in `linker.c'.
7740 These routines may simply be defined as macros. For example, the
7741 a.out backend linker hash table, which is derived from the linker hash
7742 table, uses macros for the lookup and traversal routines. These are
7743 `aout_link_hash_lookup' and `aout_link_hash_traverse' in aoutx.h.

7770 3.2 a.out backends
7771 ==================
7773 *Description*
7774 BFD supports a number of different flavours of a.out format, though the
7775 major differences are only the sizes of the structures on disk, and the
7776 shape of the relocation information.
7778 The support is split into a basic support file `aoutx.h' and other
7779 files which derive functions from the base. One derivation file is
7780 `aoutf1.h' (for a.out flavour 1), and adds to the basic a.out functions
7781 support for sun3, sun4, 386 and 29k a.out files, to create a target
7782 jump vector for a specific target.
7784 This information is further split out into more specific files for
7785 each machine, including `sunos.c' for sun3 and sun4, `newsos3.c' for
7786 the Sony NEWS, and `demo64.c' for a demonstration of a 64 bit a.out
7787 format.
7789 The base file `aoutx.h' defines general mechanisms for reading and
7790 writing records to and from disk and various other methods which BFD
7791 requires. It is included by `aout32.c' and `aout64.c' to form the names
7792 `aout_32_swap_exec_header_in', `aout_64_swap_exec_header_in', etc.
7794 As an example, this is what goes on to make the back end for a sun4,
7795 from `aout32.c':
7797 #define ARCH_SIZE 32
7798 #include "aoutx.h"
7800 Which exports names:
7802 ...
7803 aout_32_canonicalize_reloc
7804 aout_32_find_nearest_line
7805 aout_32_get_lineno
7806 aout_32_get_reloc_upper_bound
7807 ...
7809 from `sunos.c':
7811 #define TARGET_NAME "a.out-sunos-big"
7812 #define VECNAME sunos_big_vec
7813 #include "aoutf1.h"
7815 requires all the names from `aout32.c', and produces the jump vector
7817 sunos_big_vec
7819 The file `host-aout.c' is a special case. It is for a large set of
7820 hosts that use "more or less standard" a.out files, and for which
7821 cross-debugging is not interesting. It uses the standard 32-bit a.out
7822 support routines, but determines the file offsets and addresses of the
7823 text, data, and BSS sections, the machine architecture and machine
7824 type, and the entry point address, in a host-dependent manner. Once
7825 these values have been determined, generic code is used to handle the
7826 object file.
7828 When porting it to run on a new system, you must supply:
7830 HOST_PAGE_SIZE
7831 HOST_SEGMENT_SIZE
7832 HOST_MACHINE_ARCH (optional)
7833 HOST_MACHINE_MACHINE (optional)
7834 HOST_TEXT_START_ADDR
7835 HOST_STACK_END_ADDR
7837 in the file `../include/sys/h-XXX.h' (for your host). These values,
7838 plus the structures and macros defined in `a.out.h' on your host
7839 system, will produce a BFD target that will access ordinary a.out files
7840 on your host. To configure a new machine to use `host-aout.c', specify:
7842 TDEFAULTS = -DDEFAULT_VECTOR=host_aout_big_vec
7843 TDEPFILES= host-aout.o trad-core.o
7845 in the `config/XXX.mt' file, and modify `configure.in' to use the
7846 `XXX.mt' file (by setting "`bfd_target=XXX'") when your configuration
7847 is selected.
7849 3.2.1 Relocations
7850 -----------------
7852 *Description*
7853 The file `aoutx.h' provides for both the _standard_ and _extended_
7854 forms of a.out relocation records.
7856 The standard records contain only an address, a symbol index, and a
7857 type field. The extended records (used on 29ks and sparcs) also have a
7858 full integer for an addend.
7860 3.2.2 Internal entry points
7861 ---------------------------
7863 *Description*
7864 `aoutx.h' exports several routines for accessing the contents of an
7865 a.out file, which are gathered and exported in turn by various format
7866 specific files (eg sunos.c).

7957 3.3 coff backends
7958 =================
7960 BFD supports a number of different flavours of coff format. The major
7961 differences between formats are the sizes and alignments of fields in
7962 structures on disk, and the occasional extra field.
7964 Coff in all its varieties is implemented with a few common files and
7965 a number of implementation specific files. For example, The 88k bcs
7966 coff format is implemented in the file `coff-m88k.c'. This file
7967 `#include's `coff/m88k.h' which defines the external structure of the
7968 coff format for the 88k, and `coff/internal.h' which defines the
7969 internal structure. `coff-m88k.c' also defines the relocations used by
7970 the 88k format *Note Relocations::.
7972 The Intel i960 processor version of coff is implemented in
7973 `coff-i960.c'. This file has the same structure as `coff-m88k.c',
7974 except that it includes `coff/i960.h' rather than `coff-m88k.h'.
7976 3.3.1 Porting to a new version of coff
7977 --------------------------------------
7979 The recommended method is to select from the existing implementations
7980 the version of coff which is most like the one you want to use. For
7981 example, we'll say that i386 coff is the one you select, and that your
7982 coff flavour is called foo. Copy `i386coff.c' to `foocoff.c', copy
7983 `../include/coff/i386.h' to `../include/coff/foo.h', and add the lines
7984 to `targets.c' and `Makefile.in' so that your new back end is used.
7985 Alter the shapes of the structures in `../include/coff/foo.h' so that
7986 they match what you need. You will probably also have to add `#ifdef's
7987 to the code in `coff/internal.h' and `coffcode.h' if your version of
7988 coff is too wild.
7990 You can verify that your new BFD backend works quite simply by
7991 building `objdump' from the `binutils' directory, and making sure that
7992 its version of what's going on and your host system's idea (assuming it
7993 has the pretty standard coff dump utility, usually called `att-dump' or
7994 just `dump') are the same. Then clean up your code, and send what
7995 you've done to Cygnus. Then your stuff will be in the next release, and
7996 you won't have to keep integrating it.
7998 3.3.2 How the coff backend works
7999 --------------------------------
8001 3.3.2.1 File layout
8002 ...................
8004 The Coff backend is split into generic routines that are applicable to
8005 any Coff target and routines that are specific to a particular target.
8006 The target-specific routines are further split into ones which are
8007 basically the same for all Coff targets except that they use the
8008 external symbol format or use different values for certain constants.
8010 The generic routines are in `coffgen.c'. These routines work for
8011 any Coff target. They use some hooks into the target specific code;
8012 the hooks are in a `bfd_coff_backend_data' structure, one of which
8013 exists for each target.
8015 The essentially similar target-specific routines are in
8016 `coffcode.h'. This header file includes executable C code. The
8017 various Coff targets first include the appropriate Coff header file,
8018 make any special defines that are needed, and then include `coffcode.h'.
8020 Some of the Coff targets then also have additional routines in the
8021 target source file itself.
8023 For example, `coff-i960.c' includes `coff/internal.h' and
8024 `coff/i960.h'. It then defines a few constants, such as `I960', and
8025 includes `coffcode.h'. Since the i960 has complex relocation types,
8026 `coff-i960.c' also includes some code to manipulate the i960 relocs.
8027 This code is not in `coffcode.h' because it would not be used by any
8028 other target.
8030 3.3.2.2 Bit twiddling
8031 .....................
8033 Each flavour of coff supported in BFD has its own header file
8034 describing the external layout of the structures. There is also an
8035 internal description of the coff layout, in `coff/internal.h'. A major
8036 function of the coff backend is swapping the bytes and twiddling the
8037 bits to translate the external form of the structures into the normal
8038 internal form. This is all performed in the `bfd_swap'_thing_direction
8039 routines. Some elements are different sizes between different versions
8040 of coff; it is the duty of the coff version specific include file to
8041 override the definitions of various packing routines in `coffcode.h'.
8042 E.g., the size of line number entry in coff is sometimes 16 bits, and
8043 sometimes 32 bits. `#define'ing `PUT_LNSZ_LNNO' and `GET_LNSZ_LNNO'
8044 will select the correct one. No doubt, some day someone will find a
8045 version of coff which has a varying field size not catered to at the
8046 moment. To port BFD, that person will have to add more `#defines'.
8047 Three of the bit twiddling routines are exported to `gdb';
8048 `coff_swap_aux_in', `coff_swap_sym_in' and `coff_swap_lineno_in'. `GDB'
8049 reads the symbol table on its own, but uses BFD to fix things up. More
8050 of the bit twiddlers are exported for `gas'; `coff_swap_aux_out',
8051 `coff_swap_sym_out', `coff_swap_lineno_out', `coff_swap_reloc_out',
8052 `coff_swap_filehdr_out', `coff_swap_aouthdr_out',
8053 `coff_swap_scnhdr_out'. `Gas' currently keeps track of all the symbol
8054 table and reloc drudgery itself, thereby saving the internal BFD
8055 overhead, but uses BFD to swap things on the way out, making cross
8056 ports much safer. Doing so also allows BFD (and thus the linker) to
8057 use the same header files as `gas', which makes one avenue to disaster
8058 disappear.
8060 3.3.2.3 Symbol reading
8061 ......................
8063 The simple canonical form for symbols used by BFD is not rich enough to
8064 keep all the information available in a coff symbol table. The back end
8065 gets around this problem by keeping the original symbol table around,
8066 "behind the scenes".
8068 When a symbol table is requested (through a call to
8069 `bfd_canonicalize_symtab'), a request gets through to
8070 `coff_get_normalized_symtab'. This reads the symbol table from the coff
8071 file and swaps all the structures inside into the internal form. It
8072 also fixes up all the pointers in the table (represented in the file by
8073 offsets from the first symbol in the table) into physical pointers to
8074 elements in the new internal table. This involves some work since the
8075 meanings of fields change depending upon context: a field that is a
8076 pointer to another structure in the symbol table at one moment may be
8077 the size in bytes of a structure at the next. Another pass is made
8078 over the table. All symbols which mark file names (`C_FILE' symbols)
8079 are modified so that the internal string points to the value in the
8080 auxent (the real filename) rather than the normal text associated with
8081 the symbol (`".file"').
8083 At this time the symbol names are moved around. Coff stores all
8084 symbols less than nine characters long physically within the symbol
8085 table; longer strings are kept at the end of the file in the string
8086 table. This pass moves all strings into memory and replaces them with
8087 pointers to the strings.
8089 The symbol table is massaged once again, this time to create the
8090 canonical table used by the BFD application. Each symbol is inspected
8091 in turn, and a decision made (using the `sclass' field) about the
8092 various flags to set in the `asymbol'. *Note Symbols::. The generated
8093 canonical table shares strings with the hidden internal symbol table.
8095 Any linenumbers are read from the coff file too, and attached to the
8096 symbols which own the functions the linenumbers belong to.
8098 3.3.2.4 Symbol writing
8099 ......................
8101 Writing a symbol to a coff file which didn't come from a coff file will
8102 lose any debugging information. The `asymbol' structure remembers the
8103 BFD from which the symbol was taken, and on output the back end makes
8104 sure that the same destination target as source target is present.
8106 When the symbols have come from a coff file then all the debugging
8107 information is preserved.
8109 Symbol tables are provided for writing to the back end in a vector
8110 of pointers to pointers. This allows applications like the linker to
8111 accumulate and output large symbol tables without having to do too much
8112 byte copying.
8114 This function runs through the provided symbol table and patches
8115 each symbol marked as a file place holder (`C_FILE') to point to the
8116 next file place holder in the list. It also marks each `offset' field
8117 in the list with the offset from the first symbol of the current symbol.
8119 Another function of this procedure is to turn the canonical value
8120 form of BFD into the form used by coff. Internally, BFD expects symbol
8121 values to be offsets from a section base; so a symbol physically at
8122 0x120, but in a section starting at 0x100, would have the value 0x20.
8123 Coff expects symbols to contain their final value, so symbols have
8124 their values changed at this point to reflect their sum with their
8125 owning section. This transformation uses the `output_section' field of
8126 the `asymbol''s `asection' *Note Sections::.
8128 * `coff_mangle_symbols'
8129 This routine runs though the provided symbol table and uses the
8130 offsets generated by the previous pass and the pointers generated when
8131 the symbol table was read in to create the structured hierarchy
8132 required by coff. It changes each pointer to a symbol into the index
8133 into the symbol table of the asymbol.
8135 * `coff_write_symbols'
8136 This routine runs through the symbol table and patches up the
8137 symbols from their internal form into the coff way, calls the bit
8138 twiddlers, and writes out the table to the file.

8488 3.3.2.7 Writing relocations
8489 ...........................
8491 To write relocations, the back end steps though the canonical
8492 relocation table and create an `internal_reloc'. The symbol index to
8493 use is removed from the `offset' field in the symbol table supplied.
8494 The address comes directly from the sum of the section base address and
8495 the relocation offset; the type is dug directly from the howto field.
8496 Then the `internal_reloc' is swapped into the shape of an
8497 `external_reloc' and written out to disk.
8499 3.3.2.8 Reading linenumbers
8500 ...........................
8502 Creating the linenumber table is done by reading in the entire coff
8503 linenumber table, and creating another table for internal use.
8505 A coff linenumber table is structured so that each function is
8506 marked as having a line number of 0. Each line within the function is
8507 an offset from the first line in the function. The base of the line
8508 number information for the table is stored in the symbol associated
8509 with the function.
8511 Note: The PE format uses line number 0 for a flag indicating a new
8512 source file.
8514 The information is copied from the external to the internal table,
8515 and each symbol which marks a function is marked by pointing its...
8517 How does this work ?
8519 3.3.2.9 Reading relocations
8520 ...........................
8522 Coff relocations are easily transformed into the internal BFD form
8523 (`arelent').
8525 Reading a coff relocation table is done in the following stages:
8527 * Read the entire coff relocation table into memory.
8529 * Process each relocation in turn; first swap it from the external
8530 to the internal form.
8532 * Turn the symbol referenced in the relocation's symbol index into a
8533 pointer into the canonical symbol table. This table is the same
8534 as the one returned by a call to `bfd_canonicalize_symtab'. The
8535 back end will call that routine and save the result if a
8536 canonicalization hasn't been done.
8538 * The reloc index is turned into a pointer to a howto structure, in
8539 a back end specific way. For instance, the 386 and 960 use the
8540 `r_type' to directly produce an index into a howto table vector;
8541 the 88k subtracts a number from the `r_type' field and creates an
8542 addend field.

8547 3.4 ELF backends
8548 ================
8550 BFD support for ELF formats is being worked on. Currently, the best
8551 supported back ends are for sparc and i386 (running svr4 or Solaris 2).
8553 Documentation of the internals of the support code still needs to be
8554 written. The code is changing quickly enough that we haven't bothered
8555 yet.

8558 ..............................
8560 *Synopsis*
8561 struct elf_internal_shdr *bfd_elf_find_section (bfd *abfd, char *name);
8562 *Description*
8563 Helper functions for GDB to locate the string tables. Since BFD hides
8564 string tables from callers, GDB needs to use an internal hook to find
8565 them. Sun's .stabstr, in particular, isn't even pointed to by the
8566 .stab section, so ordinary mechanisms wouldn't work to find it, even if
8567 we had some.

8572 3.5 mmo backend
8573 ===============
8575 The mmo object format is used exclusively together with Professor
8576 Donald E. Knuth's educational 64-bit processor MMIX. The simulator
8577 `mmix' which is available at
8578 `http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz'
8579 understands this format. That package also includes a combined
8580 assembler and linker called `mmixal'. The mmo format has no advantages
8581 feature-wise compared to e.g. ELF. It is a simple non-relocatable
8582 object format with no support for archives or debugging information,
8583 except for symbol value information and line numbers (which is not yet
8584 implemented in BFD). See
8585 `http://www-cs-faculty.stanford.edu/~knuth/mmix.html' for more
8586 information about MMIX. The ELF format is used for intermediate object
8587 files in the BFD implementation.

8601 The mmo file contents is not partitioned into named sections as with
8602 e.g. ELF. Memory areas is formed by specifying the location of the
8603 data that follows. Only the memory area `0x0000...00' to `0x01ff...ff'
8604 is executable, so it is used for code (and constants) and the area
8605 `0x2000...00' to `0x20ff...ff' is used for writable data. *Note mmo
8606 section mapping::.
8608 There is provision for specifying "special data" of 65536 different
8609 types. We use type 80 (decimal), arbitrarily chosen the same as the
8610 ELF `e_machine' number for MMIX, filling it with section information
8611 normally found in ELF objects. *Note mmo section mapping::.
8613 Contents is entered as 32-bit words, xor:ed over previous contents,
8614 always zero-initialized. A word that starts with the byte `0x98' forms
8615 a command called a `lopcode', where the next byte distinguished between
8616 the thirteen lopcodes. The two remaining bytes, called the `Y' and `Z'
8617 fields, or the `YZ' field (a 16-bit big-endian number), are used for
8618 various purposes different for each lopcode. As documented in
8619 `http://www-cs-faculty.stanford.edu/~knuth/mmixal-intro.ps.gz', the
8620 lopcodes are:
8622 `lop_quote'
8623 0x98000001. The next word is contents, regardless of whether it
8624 starts with 0x98 or not.
8626 `lop_loc'
8627 0x9801YYZZ, where `Z' is 1 or 2. This is a location directive,
8628 setting the location for the next data to the next 32-bit word
8629 (for Z = 1) or 64-bit word (for Z = 2), plus Y * 2^56. Normally
8630 `Y' is 0 for the text segment and 2 for the data segment.
8632 `lop_skip'
8633 0x9802YYZZ. Increase the current location by `YZ' bytes.
8635 `lop_fixo'
8636 0x9803YYZZ, where `Z' is 1 or 2. Store the current location as 64
8637 bits into the location pointed to by the next 32-bit (Z = 1) or
8638 64-bit (Z = 2) word, plus Y * 2^56.
8640 `lop_fixr'
8641 0x9804YYZZ. `YZ' is stored into the current location plus 2 - 4 *
8642 YZ.
8644 `lop_fixrx'
8645 0x980500ZZ. `Z' is 16 or 24. A value `L' derived from the
8646 following 32-bit word are used in a manner similar to `YZ' in
8647 lop_fixr: it is xor:ed into the current location minus 4 * L. The
8648 first byte of the word is 0 or 1. If it is 1, then L = (LOWEST 24
8649 BITS OF WORD) - 2^Z, if 0, then L = (LOWEST 24 BITS OF WORD).
8651 `lop_file'
8652 0x9806YYZZ. `Y' is the file number, `Z' is count of 32-bit words.
8653 Set the file number to `Y' and the line counter to 0. The next Z
8654 * 4 bytes contain the file name, padded with zeros if the count is
8655 not a multiple of four. The same `Y' may occur multiple times,
8656 but `Z' must be 0 for all but the first occurrence.
8658 `lop_line'
8659 0x9807YYZZ. `YZ' is the line number. Together with lop_file, it
8660 forms the source location for the next 32-bit word. Note that for
8661 each non-lopcode 32-bit word, line numbers are assumed incremented
8662 by one.
8664 `lop_spec'
8665 0x9808YYZZ. `YZ' is the type number. Data until the next lopcode
8666 other than lop_quote forms special data of type `YZ'. *Note mmo
8667 section mapping::.
8669 Other types than 80, (or type 80 with a content that does not
8670 parse) is stored in sections named `.MMIX.spec_data.N' where N is
8671 the `YZ'-type. The flags for such a sections say not to allocate
8672 or load the data. The vma is 0. Contents of multiple occurrences
8673 of special data N is concatenated to the data of the previous
8674 lop_spec Ns. The location in data or code at which the lop_spec
8675 occurred is lost.
8677 `lop_pre'
8678 0x980901ZZ. The first lopcode in a file. The `Z' field forms the
8679 length of header information in 32-bit words, where the first word
8680 tells the time in seconds since `00:00:00 GMT Jan 1 1970'.
8682 `lop_post'
8683 0x980a00ZZ. Z > 32. This lopcode follows after all
8684 content-generating lopcodes in a program. The `Z' field denotes
8685 the value of `rG' at the beginning of the program. The following
8686 256 - Z big-endian 64-bit words are loaded into global registers
8687 `$G' ... `$255'.
8689 `lop_stab'
8690 0x980b0000. The next-to-last lopcode in a program. Must follow
8691 immediately after the lop_post lopcode and its data. After this
8692 lopcode follows all symbols in a compressed format (*note
8693 Symbol-table::).
8695 `lop_end'
8696 0x980cYYZZ. The last lopcode in a program. It must follow the
8697 lop_stab lopcode and its data. The `YZ' field contains the number
8698 of 32-bit words of symbol table information after the preceding
8699 lop_stab lopcode.
8701 Note that the lopcode "fixups"; `lop_fixr', `lop_fixrx' and
8702 `lop_fixo' are not generated by BFD, but are handled. They are
8703 generated by `mmixal'.
8705 This trivial one-label, one-instruction file:
8707 :Main TRAP 1,2,3
8709 can be represented this way in mmo:
8711 0x98090101 - lop_pre, one 32-bit word with timestamp.
8712 <timestamp>
8713 0x98010002 - lop_loc, text segment, using a 64-bit address.
8714 Note that mmixal does not emit this for the file above.
8715 0x00000000 - Address, high 32 bits.
8716 0x00000000 - Address, low 32 bits.
8717 0x98060002 - lop_file, 2 32-bit words for file-name.
8718 0x74657374 - "test"
8719 0x2e730000 - ".s\0\0"
8720 0x98070001 - lop_line, line 1.
8721 0x00010203 - TRAP 1,2,3
8722 0x980a00ff - lop_post, setting $255 to 0.
8723 0x00000000
8724 0x00000000
8725 0x980b0000 - lop_stab for ":Main" = 0, serial 1.
8726 0x203a4040 *Note Symbol-table::.
8727 0x10404020
8728 0x4d206120
8729 0x69016e00
8730 0x81000000
8731 0x980c0005 - lop_end; symbol table contained five 32-bit words.

8736 3.5.2 Symbol table format
8737 -------------------------
8739 From mmixal.w (or really, the generated mmixal.tex) in
8740 `http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz'):
8741 "Symbols are stored and retrieved by means of a `ternary search trie',
8742 following ideas of Bentley and Sedgewick. (See ACM-SIAM Symp. on
8743 Discrete Algorithms `8' (1997), 360-369; R.Sedgewick, `Algorithms in C'
8744 (Reading, Mass. Addison-Wesley, 1998), `15.4'.) Each trie node stores
8745 a character, and there are branches to subtries for the cases where a
8746 given character is less than, equal to, or greater than the character
8747 in the trie. There also is a pointer to a symbol table entry if a
8748 symbol ends at the current node."
8750 So it's a tree encoded as a stream of bytes. The stream of bytes
8751 acts on a single virtual global symbol, adding and removing characters
8752 and signalling complete symbol points. Here, we read the stream and
8753 create symbols at the completion points.
8755 First, there's a control byte `m'. If any of the listed bits in `m'
8756 is nonzero, we execute what stands at the right, in the listed order:
8758 (MMO3_LEFT)
8759 0x40 - Traverse left trie.
8760 (Read a new command byte and recurse.)
8762 (MMO3_SYMBITS)
8763 0x2f - Read the next byte as a character and store it in the
8764 current character position; increment character position.
8765 Test the bits of `m':
8767 (MMO3_WCHAR)
8768 0x80 - The character is 16-bit (so read another byte,
8769 merge into current character.
8771 (MMO3_TYPEBITS)
8772 0xf - We have a complete symbol; parse the type, value
8773 and serial number and do what should be done
8774 with a symbol. The type and length information
8775 is in j = (m & 0xf).
8777 (MMO3_REGQUAL_BITS)
8778 j == 0xf: A register variable. The following
8779 byte tells which register.
8780 j <= 8: An absolute symbol. Read j bytes as the
8781 big-endian number the symbol equals.
8782 A j = 2 with two zero bytes denotes an
8783 unknown symbol.
8784 j > 8: As with j <= 8, but add (0x20 << 56)
8785 to the value in the following j - 8
8786 bytes.
8788 Then comes the serial number, as a variant of
8789 uleb128, but better named ubeb128:
8790 Read bytes and shift the previous value left 7
8791 (multiply by 128). Add in the new byte, repeat
8792 until a byte has bit 7 set. The serial number
8793 is the computed value minus 128.
8795 (MMO3_MIDDLE)
8796 0x20 - Traverse middle trie. (Read a new command byte
8797 and recurse.) Decrement character position.
8799 (MMO3_RIGHT)
8800 0x10 - Traverse right trie. (Read a new command byte and
8801 recurse.)
8803 Let's look again at the `lop_stab' for the trivial file (*note File
8804 layout::).
8806 0x980b0000 - lop_stab for ":Main" = 0, serial 1.
8807 0x203a4040
8808 0x10404020
8809 0x4d206120
8810 0x69016e00
8811 0x81000000
8813 This forms the trivial trie (note that the path between ":" and "M"
8814 is redundant):
8816 203a ":"
8817 40 /
8818 40 /
8819 10 \
8820 40 /
8821 40 /
8822 204d "M"
8823 2061 "a"
8824 2069 "i"
8825 016e "n" is the last character in a full symbol, and
8826 with a value represented in one byte.
8827 00 The value is 0.
8828 81 The serial number is 1.

8833 3.5.3 mmo section mapping
8834 -------------------------
8836 The implementation in BFD uses special data type 80 (decimal) to
8837 encapsulate and describe named sections, containing e.g. debug
8838 information. If needed, any datum in the encapsulation will be quoted
8839 using lop_quote. First comes a 32-bit word holding the number of
8840 32-bit words containing the zero-terminated zero-padded segment name.
8841 After the name there's a 32-bit word holding flags describing the
8842 section type. Then comes a 64-bit big-endian word with the section
8843 length (in bytes), then another with the section start address.
8844 Depending on the type of section, the contents might follow,
8845 zero-padded to 32-bit boundary. For a loadable section (such as data
8846 or code), the contents might follow at some later point, not
8847 necessarily immediately, as a lop_loc with the same start address as in
8848 the section description, followed by the contents. This in effect
8849 forms a descriptor that must be emitted before the actual contents.
8850 Sections described this way must not overlap.
8852 For areas that don't have such descriptors, synthetic sections are
8853 formed by BFD. Consecutive contents in the two memory areas
8854 `0x0000...00' to `0x01ff...ff' and `0x2000...00' to `0x20ff...ff' are
8855 entered in sections named `.text' and `.data' respectively. If an area
8856 is not otherwise described, but would together with a neighboring lower
8857 area be less than `0x40000000' bytes long, it is joined with the lower
8858 area and the gap is zero-filled. For other cases, a new section is
8859 formed, named `.MMIX.sec.N'. Here, N is a number, a running count
8860 through the mmo file, starting at 0.
8862 A loadable section specified as:
8864 .section secname,"ax"
8865 TETRA 1,2,3,4,-1,-2009
8866 BYTE 80
8868 and linked to address `0x4', is represented by the sequence:
8870 0x98080050 - lop_spec 80
8871 0x00000002 - two 32-bit words for the section name
8872 0x7365636e - "secn"
8873 0x616d6500 - "ame\0"
8874 0x00000033 - flags CODE, READONLY, LOAD, ALLOC
8875 0x00000000 - high 32 bits of section length
8876 0x0000001c - section length is 28 bytes; 6 * 4 + 1 + alignment to 32 bits
8877 0x00000000 - high 32 bits of section address
8878 0x00000004 - section address is 4
8879 0x98010002 - 64 bits with address of following data
8880 0x00000000 - high 32 bits of address
8881 0x00000004 - low 32 bits: data starts at address 4
8882 0x00000001 - 1
8883 0x00000002 - 2
8884 0x00000003 - 3
8885 0x00000004 - 4
8886 0xffffffff - -1
8887 0xfffff827 - -2009
8888 0x50000000 - 80 as a byte, padded with zeros.
8890 Note that the lop_spec wrapping does not include the section
8891 contents. Compare this to a non-loaded section specified as:
8893 .section thirdsec
8894 TETRA 200001,100002
8895 BYTE 38,40
8897 This, when linked to address `0x200000000000001c', is represented by:
8899 0x98080050 - lop_spec 80
8900 0x00000002 - two 32-bit words for the section name
8901 0x7365636e - "thir"
8902 0x616d6500 - "dsec"
8903 0x00000010 - flag READONLY
8904 0x00000000 - high 32 bits of section length
8905 0x0000000c - section length is 12 bytes; 2 * 4 + 2 + alignment to 32 bits
8906 0x20000000 - high 32 bits of address
8907 0x0000001c - low 32 bits of address 0x200000000000001c
8908 0x00030d41 - 200001
8909 0x000186a2 - 100002
8910 0x26280000 - 38, 40 as bytes, padded with zeros
8912 For the latter example, the section contents must not be loaded in
8913 memory, and is therefore specified as part of the special data. The
8914 address is usually unimportant but might provide information for e.g.
8915 the DWARF 2 debugging format.

8926 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
8928 Everyone is permitted to copy and distribute verbatim copies
8929 of this license document, but changing it is not allowed.
8932 0. PREAMBLE
8934 The purpose of this License is to make a manual, textbook, or other
8935 written document "free" in the sense of freedom: to assure everyone
8936 the effective freedom to copy and redistribute it, with or without
8937 modifying it, either commercially or noncommercially. Secondarily,
8938 this License preserves for the author and publisher a way to get
8939 credit for their work, while not being considered responsible for
8940 modifications made by others.
8942 This License is a kind of "copyleft", which means that derivative
8943 works of the document must themselves be free in the same sense.
8944 It complements the GNU General Public License, which is a copyleft
8945 license designed for free software.
8947 We have designed this License in order to use it for manuals for
8948 free software, because free software needs free documentation: a
8949 free program should come with manuals providing the same freedoms
8950 that the software does. But this License is not limited to
8951 software manuals; it can be used for any textual work, regardless
8952 of subject matter or whether it is published as a printed book.
8953 We recommend this License principally for works whose purpose is
8954 instruction or reference.
8957 1. APPLICABILITY AND DEFINITIONS
8959 This License applies to any manual or other work that contains a
8960 notice placed by the copyright holder saying it can be distributed
8961 under the terms of this License. The "Document", below, refers to
8962 any such manual or work. Any member of the public is a licensee,
8963 and is addressed as "you."
8965 A "Modified Version" of the Document means any work containing the
8966 Document or a portion of it, either copied verbatim, or with
8967 modifications and/or translated into another language.
8969 A "Secondary Section" is a named appendix or a front-matter
8970 section of the Document that deals exclusively with the
8971 relationship of the publishers or authors of the Document to the
8972 Document's overall subject (or to related matters) and contains
8973 nothing that could fall directly within that overall subject.
8974 (For example, if the Document is in part a textbook of
8975 mathematics, a Secondary Section may not explain any mathematics.)
8976 The relationship could be a matter of historical connection with
8977 the subject or with related matters, or of legal, commercial,
8978 philosophical, ethical or political position regarding them.
8980 The "Invariant Sections" are certain Secondary Sections whose
8981 titles are designated, as being those of Invariant Sections, in
8982 the notice that says that the Document is released under this
8983 License.
8985 The "Cover Texts" are certain short passages of text that are
8986 listed, as Front-Cover Texts or Back-Cover Texts, in the notice
8987 that says that the Document is released under this License.
8989 A "Transparent" copy of the Document means a machine-readable copy,
8990 represented in a format whose specification is available to the
8991 general public, whose contents can be viewed and edited directly
8992 and straightforwardly with generic text editors or (for images
8993 composed of pixels) generic paint programs or (for drawings) some
8994 widely available drawing editor, and that is suitable for input to
8995 text formatters or for automatic translation to a variety of
8996 formats suitable for input to text formatters. A copy made in an
8997 otherwise Transparent file format whose markup has been designed
8998 to thwart or discourage subsequent modification by readers is not
8999 Transparent. A copy that is not "Transparent" is called "Opaque."
9001 Examples of suitable formats for Transparent copies include plain
9002 ASCII without markup, Texinfo input format, LaTeX input format,
9003 SGML or XML using a publicly available DTD, and
9004 standard-conforming simple HTML designed for human modification.
9005 Opaque formats include PostScript, PDF, proprietary formats that
9006 can be read and edited only by proprietary word processors, SGML
9007 or XML for which the DTD and/or processing tools are not generally
9008 available, and the machine-generated HTML produced by some word
9009 processors for output purposes only.
9011 The "Title Page" means, for a printed book, the title page itself,
9012 plus such following pages as are needed to hold, legibly, the
9013 material this License requires to appear in the title page. For
9014 works in formats which do not have any title page as such, "Title
9015 Page" means the text near the most prominent appearance of the
9016 work's title, preceding the beginning of the body of the text.
9018 2. VERBATIM COPYING
9020 You may copy and distribute the Document in any medium, either
9021 commercially or noncommercially, provided that this License, the
9022 copyright notices, and the license notice saying this License
9023 applies to the Document are reproduced in all copies, and that you
9024 add no other conditions whatsoever to those of this License. You
9025 may not use technical measures to obstruct or control the reading
9026 or further copying of the copies you make or distribute. However,
9027 you may accept compensation in exchange for copies. If you
9028 distribute a large enough number of copies you must also follow
9029 the conditions in section 3.
9031 You may also lend copies, under the same conditions stated above,
9032 and you may publicly display copies.
9034 3. COPYING IN QUANTITY
9036 If you publish printed copies of the Document numbering more than
9037 100, and the Document's license notice requires Cover Texts, you
9038 must enclose the copies in covers that carry, clearly and legibly,
9039 all these Cover Texts: Front-Cover Texts on the front cover, and
9040 Back-Cover Texts on the back cover. Both covers must also clearly
9041 and legibly identify you as the publisher of these copies. The
9042 front cover must present the full title with all words of the
9043 title equally prominent and visible. You may add other material
9044 on the covers in addition. Copying with changes limited to the
9045 covers, as long as they preserve the title of the Document and
9046 satisfy these conditions, can be treated as verbatim copying in
9047 other respects.
9049 If the required texts for either cover are too voluminous to fit
9050 legibly, you should put the first ones listed (as many as fit
9051 reasonably) on the actual cover, and continue the rest onto
9052 adjacent pages.
9054 If you publish or distribute Opaque copies of the Document
9055 numbering more than 100, you must either include a
9056 machine-readable Transparent copy along with each Opaque copy, or
9057 state in or with each Opaque copy a publicly-accessible
9058 computer-network location containing a complete Transparent copy
9059 of the Document, free of added material, which the general
9060 network-using public has access to download anonymously at no
9061 charge using public-standard network protocols. If you use the
9062 latter option, you must take reasonably prudent steps, when you
9063 begin distribution of Opaque copies in quantity, to ensure that
9064 this Transparent copy will remain thus accessible at the stated
9065 location until at least one year after the last time you
9066 distribute an Opaque copy (directly or through your agents or
9067 retailers) of that edition to the public.
9069 It is requested, but not required, that you contact the authors of
9070 the Document well before redistributing any large number of
9071 copies, to give them a chance to provide you with an updated
9072 version of the Document.
9074 4. MODIFICATIONS
9076 You may copy and distribute a Modified Version of the Document
9077 under the conditions of sections 2 and 3 above, provided that you
9078 release the Modified Version under precisely this License, with
9079 the Modified Version filling the role of the Document, thus
9080 licensing distribution and modification of the Modified Version to
9081 whoever possesses a copy of it. In addition, you must do these
9082 things in the Modified Version:
9084 A. Use in the Title Page (and on the covers, if any) a title
9085 distinct from that of the Document, and from those of previous
9086 versions (which should, if there were any, be listed in the
9087 History section of the Document). You may use the same title
9088 as a previous version if the original publisher of that version
9089 gives permission.
9090 B. List on the Title Page, as authors, one or more persons or
9091 entities responsible for authorship of the modifications in the
9092 Modified Version, together with at least five of the principal
9093 authors of the Document (all of its principal authors, if it
9094 has less than five).
9095 C. State on the Title page the name of the publisher of the
9096 Modified Version, as the publisher.
9097 D. Preserve all the copyright notices of the Document.
9098 E. Add an appropriate copyright notice for your modifications
9099 adjacent to the other copyright notices.
9100 F. Include, immediately after the copyright notices, a license
9101 notice giving the public permission to use the Modified Version
9102 under the terms of this License, in the form shown in the
9103 Addendum below.
9104 G. Preserve in that license notice the full lists of Invariant
9105 Sections and required Cover Texts given in the Document's
9106 license notice.
9107 H. Include an unaltered copy of this License.
9108 I. Preserve the section entitled "History", and its title, and add
9109 to it an item stating at least the title, year, new authors, and
9110 publisher of the Modified Version as given on the Title Page.
9111 If there is no section entitled "History" in the Document,
9112 create one stating the title, year, authors, and publisher of
9113 the Document as given on its Title Page, then add an item
9114 describing the Modified Version as stated in the previous
9115 sentence.
9116 J. Preserve the network location, if any, given in the Document for
9117 public access to a Transparent copy of the Document, and
9118 likewise the network locations given in the Document for
9119 previous versions it was based on. These may be placed in the
9120 "History" section. You may omit a network location for a work
9121 that was published at least four years before the Document
9122 itself, or if the original publisher of the version it refers
9123 to gives permission.
9124 K. In any section entitled "Acknowledgements" or "Dedications",
9125 preserve the section's title, and preserve in the section all the
9126 substance and tone of each of the contributor acknowledgements
9127 and/or dedications given therein.
9128 L. Preserve all the Invariant Sections of the Document,
9129 unaltered in their text and in their titles. Section numbers
9130 or the equivalent are not considered part of the section titles.
9131 M. Delete any section entitled "Endorsements." Such a section
9132 may not be included in the Modified Version.
9133 N. Do not retitle any existing section as "Endorsements" or to
9134 conflict in title with any Invariant Section.
9136 If the Modified Version includes new front-matter sections or
9137 appendices that qualify as Secondary Sections and contain no
9138 material copied from the Document, you may at your option
9139 designate some or all of these sections as invariant. To do this,
9140 add their titles to the list of Invariant Sections in the Modified
9141 Version's license notice. These titles must be distinct from any
9142 other section titles.
9144 You may add a section entitled "Endorsements", provided it contains
9145 nothing but endorsements of your Modified Version by various
9146 parties-for example, statements of peer review or that the text has
9147 been approved by an organization as the authoritative definition
9148 of a standard.
9150 You may add a passage of up to five words as a Front-Cover Text,
9151 and a passage of up to 25 words as a Back-Cover Text, to the end
9152 of the list of Cover Texts in the Modified Version. Only one
9153 passage of Front-Cover Text and one of Back-Cover Text may be
9154 added by (or through arrangements made by) any one entity. If the
9155 Document already includes a cover text for the same cover,
9156 previously added by you or by arrangement made by the same entity
9157 you are acting on behalf of, you may not add another; but you may
9158 replace the old one, on explicit permission from the previous
9159 publisher that added the old one.
9161 The author(s) and publisher(s) of the Document do not by this
9162 License give permission to use their names for publicity for or to
9163 assert or imply endorsement of any Modified Version.
9165 5. COMBINING DOCUMENTS
9167 You may combine the Document with other documents released under
9168 this License, under the terms defined in section 4 above for
9169 modified versions, provided that you include in the combination
9170 all of the Invariant Sections of all of the original documents,
9171 unmodified, and list them all as Invariant Sections of your
9172 combined work in its license notice.
9174 The combined work need only contain one copy of this License, and
9175 multiple identical Invariant Sections may be replaced with a single
9176 copy. If there are multiple Invariant Sections with the same name
9177 but different contents, make the title of each such section unique
9178 by adding at the end of it, in parentheses, the name of the
9179 original author or publisher of that section if known, or else a
9180 unique number. Make the same adjustment to the section titles in
9181 the list of Invariant Sections in the license notice of the
9182 combined work.
9184 In the combination, you must combine any sections entitled
9185 "History" in the various original documents, forming one section
9186 entitled "History"; likewise combine any sections entitled
9187 "Acknowledgements", and any sections entitled "Dedications." You
9188 must delete all sections entitled "Endorsements."
9190 6. COLLECTIONS OF DOCUMENTS
9192 You may make a collection consisting of the Document and other
9193 documents released under this License, and replace the individual
9194 copies of this License in the various documents with a single copy
9195 that is included in the collection, provided that you follow the
9196 rules of this License for verbatim copying of each of the
9197 documents in all other respects.
9199 You may extract a single document from such a collection, and
9200 distribute it individually under this License, provided you insert
9201 a copy of this License into the extracted document, and follow
9202 this License in all other respects regarding verbatim copying of
9203 that document.
9205 7. AGGREGATION WITH INDEPENDENT WORKS
9207 A compilation of the Document or its derivatives with other
9208 separate and independent documents or works, in or on a volume of
9209 a storage or distribution medium, does not as a whole count as a
9210 Modified Version of the Document, provided no compilation
9211 copyright is claimed for the compilation. Such a compilation is
9212 called an "aggregate", and this License does not apply to the
9213 other self-contained works thus compiled with the Document, on
9214 account of their being thus compiled, if they are not themselves
9215 derivative works of the Document.
9217 If the Cover Text requirement of section 3 is applicable to these
9218 copies of the Document, then if the Document is less than one
9219 quarter of the entire aggregate, the Document's Cover Texts may be
9220 placed on covers that surround only the Document within the
9221 aggregate. Otherwise they must appear on covers around the whole
9222 aggregate.
9224 8. TRANSLATION
9226 Translation is considered a kind of modification, so you may
9227 distribute translations of the Document under the terms of section
9228 4. Replacing Invariant Sections with translations requires special
9229 permission from their copyright holders, but you may include
9230 translations of some or all Invariant Sections in addition to the
9231 original versions of these Invariant Sections. You may include a
9232 translation of this License provided that you also include the
9233 original English version of this License. In case of a
9234 disagreement between the translation and the original English
9235 version of this License, the original English version will prevail.
9237 9. TERMINATION
9239 You may not copy, modify, sublicense, or distribute the Document
9240 except as expressly provided for under this License. Any other
9241 attempt to copy, modify, sublicense or distribute the Document is
9242 void, and will automatically terminate your rights under this
9243 License. However, parties who have received copies, or rights,
9244 from you under this License will not have their licenses
9245 terminated so long as such parties remain in full compliance.
9247 10. FUTURE REVISIONS OF THIS LICENSE
9249 The Free Software Foundation may publish new, revised versions of
9250 the GNU Free Documentation License from time to time. Such new
9251 versions will be similar in spirit to the present version, but may
9252 differ in detail to address new problems or concerns. See
9253 http://www.gnu.org/copyleft/.
9255 Each version of the License is given a distinguishing version
9256 number. If the Document specifies that a particular numbered
9257 version of this License "or any later version" applies to it, you
9258 have the option of following the terms and conditions either of
9259 that specified version or of any later version that has been
9260 published (not as a draft) by the Free Software Foundation. If
9261 the Document does not specify a version number of this License,
9262 you may choose any version ever published (not as a draft) by the
9263 Free Software Foundation.
9266 ADDENDUM: How to use this License for your documents
9267 ====================================================
9269 To use this License in a document you have written, include a copy of
9270 the License in the document and put the following copyright and license
9271 notices just after the title page:
9273 Copyright (C) YEAR YOUR NAME.
9274 Permission is granted to copy, distribute and/or modify this document
9275 under the terms of the GNU Free Documentation License, Version 1.1
9276 or any later version published by the Free Software Foundation;
9277 with the Invariant Sections being LIST THEIR TITLES, with the
9278 Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
9279 A copy of the license is included in the section entitled "GNU
9280 Free Documentation License."
9282 If you have no Invariant Sections, write "with no Invariant Sections"
9283 instead of saying which ones are invariant. If you have no Front-Cover
9284 Texts, write "no Front-Cover Texts" instead of "Front-Cover Texts being
9285 LIST"; likewise for Back-Cover Texts.
9287 If your document contains nontrivial examples of program code, we
9288 recommend releasing these examples in parallel under your choice of
9289 free software license, such as the GNU General Public License, to
9290 permit their use in free software.
