     48 1 Introduction
     49 **************
     50 
     51 BFD is a package which allows applications to use the same routines to
     52 operate on object files whatever the object file format.  A new object
     53 file format can be supported simply by creating a new BFD back end and
     54 adding it to the library.
     55 
     56    BFD is split into two parts: the front end, and the back ends (one
     57 for each object file format).
     58    * The front end of BFD provides the interface to the user. It manages
     59      memory and various canonical data structures. The front end also
     60      decides which back end to use and when to call back end routines.
     61 
     62    * The back ends provide BFD its view of the real world. Each back
     63      end provides a set of calls which the BFD front end can use to
     64      maintain its canonical form. The back ends also may keep around
     65      information for their own use, for greater efficiency.

     76 1.1 History
     77 ===========
     78 
     79 One spur behind BFD was the desire, on the part of the GNU 960 team at
     80 Intel Oregon, for interoperability of applications on their COFF and
     81 b.out file formats.  Cygnus was providing GNU support for the team, and
     82 was contracted to provide the required functionality.
     83 
     84    The name came from a conversation David Wallace was having with
     85 Richard Stallman about the library: RMS said that it would be quite
     86 hard--David said "BFD".  Stallman was right, but the name stuck.
     87 
     88    At the same time, Ready Systems wanted much the same thing, but for
     89 different object file formats: IEEE-695, Oasys, Srecords, a.out and 68k
     90 coff.
     91 
     92    BFD was first implemented by members of Cygnus Support; Steve
     93 Chamberlain (`sac (a] cygnus.com'), John Gilmore (`gnu (a] cygnus.com'), K.
     94 Richard Pixley (`rich (a] cygnus.com') and David Henkel-Wallace
     95 (`gumby (a] cygnus.com').

     99 
    100 1.2 How To Use BFD
    101 ==================
    102 
    103 To use the library, include `bfd.h' and link with `libbfd.a'.
    104 
    105    BFD provides a common interface to the parts of an object file for a
    106 calling application.
    107 
    108    When an application successfully opens a target file (object,
    109 archive, or whatever), a pointer to an internal structure is returned.
    110 This pointer points to a structure called `bfd', described in `bfd.h'.
    111 Our convention is to call this pointer a BFD, and instances of it
    112 within code `abfd'.  All operations on the target object file are
    113 applied as methods to the BFD.  The mapping is defined within `bfd.h'
    114 in a set of macros, all beginning with `bfd_' to reduce namespace
    115 pollution.
    116 
    117    For example, this sequence does what you would probably expect:
    118 return the number of sections in an object file attached to a BFD
    119 `abfd'.
    120 
    121      #include "bfd.h"
    122 
    123      unsigned int number_of_sections (abfd)
    124      bfd *abfd;
    125      {
    126        return bfd_count_sections (abfd);
    127      }
    128 
    129    The abstraction used within BFD is that an object file has:
    130 
    131    * a header,
    132 
    133    * a number of sections containing raw data (*note Sections::),
    134 
    135    * a set of relocations (*note Relocations::), and
    136 
    137    * some symbol information (*note Symbols::).
    138    Also, BFDs opened for archives have the additional attribute of an
    139 index and contain subordinate BFDs. This approach is fine for a.out and
    140 coff, but loses efficiency when applied to formats such as S-records and
    141 IEEE-695.
    142 
    143 
    144 File: bfd.info,  Node: What BFD Version 2 Can Do,  Prev: How It Works,  Up: Overview
    145 
    146 1.3 What BFD Version 2 Can Do
    147 =============================
    148 
    149 When an object file is opened, BFD subroutines automatically determine
    150 the format of the input object file.  They then build a descriptor in
    151 memory with pointers to routines that will be used to access elements of
    152 the object file's data structures.
    153 
    154    As different information from the object files is required, BFD
    155 reads from different sections of the file and processes them.  For
    156 example, a very common operation for the linker is processing symbol
    157 tables.  Each BFD back end provides a routine for converting between
    158 the object file's representation of symbols and an internal canonical
    159 format. When the linker asks for the symbol table of an object file, it
    160 calls through a memory pointer to the routine from the relevant BFD
    161 back end which reads and converts the table into a canonical form.  The
    162 linker then operates upon the canonical form. When the link is finished
    163 and the linker writes the output file's symbol table, another BFD back
    164 end routine is called to take the newly created symbol table and
    165 convert it into the chosen output format.

    173 File: bfd.info,  Node: BFD information loss,  Next: Canonical format,  Up: What BFD Version 2 Can Do
    174 
    175 1.3.1 Information Loss
    176 ----------------------
    177 
    178 _Information can be lost during output._ The output formats supported
    179 by BFD do not provide identical facilities, and information which can
    180 be described in one form has nowhere to go in another format. One
    181 example of this is alignment information in `b.out'. There is nowhere
    182 in an `a.out' format file to store alignment information on the
    183 contained data, so when a file is linked from `b.out' and an `a.out'
    184 image is produced, alignment information will not propagate to the
    185 output file. (The linker will still use the alignment information
    186 internally, so the link is performed correctly).
    187 
    188    Another example is COFF section names. COFF files may contain an
    189 unlimited number of sections, each one with a textual section name. If
    190 the target of the link is a format which does not have many sections
    191 (e.g., `a.out') or has sections without names (e.g., the Oasys format),
    192 the link cannot be done simply. You can circumvent this problem by
    193 describing the desired input-to-output section mapping with the linker
    194 command language.
    195 
    196    _Information can be lost during canonicalization._ The BFD internal
    197 canonical form of the external formats is not exhaustive; there are
    198 structures in input formats for which there is no direct representation
    199 internally.  This means that the BFD back ends cannot maintain all
    200 possible data richness through the transformation between external to
    201 internal and back to external formats.
    202 
    203    This limitation is only a problem when an application reads one
    204 format and writes another.  Each BFD back end is responsible for
    205 maintaining as much data as possible, and the internal BFD canonical
    206 form has structures which are opaque to the BFD core, and exported only
    207 to the back ends. When a file is read in one format, the canonical form
    208 is generated for BFD and the application. At the same time, the back
    209 end saves away any information which may otherwise be lost. If the data
    210 is then written back in the same format, the back end routine will be
    211 able to use the canonical form provided by the BFD core as well as the
    212 information it prepared earlier.  Since there is a great deal of
    213 commonality between back ends, there is no information lost when
    214 linking or copying big endian COFF to little endian COFF, or `a.out' to
    215 `b.out'.  When a mixture of formats is linked, the information is only
    216 lost from the files whose format differs from the destination.

    220 
    221 1.3.2 The BFD canonical object-file format
    222 ------------------------------------------
    223 
    224 The greatest potential for loss of information occurs when there is the
    225 least overlap between the information provided by the source format,
    226 that stored by the canonical format, and that needed by the destination
    227 format. A brief description of the canonical form may help you
    228 understand which kinds of data you can count on preserving across
    229 conversions.  
    230 
    231 _files_
    232      Information stored on a per-file basis includes target machine
    233      architecture, particular implementation format type, a demand
    234      pageable bit, and a write protected bit.  Information like Unix
    235      magic numbers is not stored here--only the magic numbers' meaning,
    236      so a `ZMAGIC' file would have both the demand pageable bit and the
    237      write protected text bit set.  The byte order of the target is
    238      stored on a per-file basis, so that big- and little-endian object
    239      files may be used with one another.
    240 
    241 _sections_
    242      Each section in the input file contains the name of the section,
    243      the section's original address in the object file, size and
    244      alignment information, various flags, and pointers into other BFD
    245      data structures.
    246 
    247 _symbols_
    248      Each symbol contains a pointer to the information for the object
    249      file which originally defined it, its name, its value, and various
    250      flag bits.  When a BFD back end reads in a symbol table, it
    251      relocates all symbols to make them relative to the base of the
    252      section where they were defined.  Doing this ensures that each
    253      symbol points to its containing section.  Each symbol also has a
    254      varying amount of hidden private data for the BFD back end.  Since
    255      the symbol points to the original file, the private data format
    256      for that symbol is accessible.  `ld' can operate on a collection
    257      of symbols of wildly different formats without problems.
    258 
    259      Normal global and simple local symbols are maintained on output,
    260      so an output file (no matter its format) will retain symbols
    261      pointing to functions and to global, static, and common variables.
    262      Some symbol information is not worth retaining; in `a.out', type
    263      information is stored in the symbol table as long symbol names.
    264      This information would be useless to most COFF debuggers; the
    265      linker has command line switches to allow users to throw it away.
    266 
    267      There is one word of type information within the symbol, so if the
    268      format supports symbol type information within symbols (for
    269      example, COFF, IEEE, Oasys) and the type is simple enough to fit
    270      within one word (nearly everything but aggregates), the
    271      information will be preserved.
    272 
    273 _relocation level_
    274      Each canonical BFD relocation record contains a pointer to the
    275      symbol to relocate to, the offset of the data to relocate, the
    276      section the data is in, and a pointer to a relocation type
    277      descriptor. Relocation is performed by passing messages through
    278      the relocation type descriptor and the symbol pointer. Therefore,
    279      relocations can be performed on output data using a relocation
    280      method that is only available in one of the input formats. For
    281      instance, Oasys provides a byte relocation format.  A relocation
    282      record requesting this relocation type would point indirectly to a
    283      routine to perform this, so the relocation may be performed on a
    284      byte being written to a 68k COFF file, even though 68k COFF has no
    285      such relocation type.
    286 
    287 _line numbers_
    288      Object formats can contain, for debugging purposes, some form of
    289      mapping between symbols, source line numbers, and addresses in the
    290      output file.  These addresses have to be relocated along with the
    291      symbol information.  Each symbol with an associated list of line
    292      number records points to the first record of the list.  The head
    293      of a line number list consists of a pointer to the symbol, which
    294      allows finding out the address of the function whose line number
    295      is being described. The rest of the list is made up of pairs:
    296      offsets into the section and line numbers. Any format which can
    297      simply derive this information can pass it successfully between
    298      formats (COFF, IEEE and Oasys).

    589 2.2 Error reporting
    590 ===================
    591 
    592 Most BFD functions return nonzero on success (check their individual
    593 documentation for precise semantics).  On an error, they call
    594 `bfd_set_error' to set an error condition that callers can check by
    595 calling `bfd_get_error'.  If that returns `bfd_error_system_call', then
    596 check `errno'.
    597 
    598    The easiest way to report a BFD error to the user is to use
    599 `bfd_perror'.
    600 
    601 2.2.1 Type `bfd_error_type'
    602 ---------------------------
    603 
    604 The values returned by `bfd_get_error' are defined by the enumerated
    605 type `bfd_error_type'.

    647    *Description*
    648 Set the BFD error condition to be ERROR_TAG.  If ERROR_TAG is
    649 bfd_error_on_input, then this function takes two more parameters, the
    650 input bfd where the error occurred, and the bfd_error_type error.

    663 
    664 *Synopsis*
    665      void bfd_perror (const char *message);
    666    *Description*
    667 Print to the standard error stream a string describing the last BFD
    668 error that occurred, or the last system error if the last BFD error was
    669 a system call failure.  If MESSAGE is non-NULL and non-empty, the error
    670 string printed is preceded by MESSAGE, a colon, and a space.  It is
    671 followed by a newline.
    672 
    673 2.2.2 BFD error handler
    674 -----------------------
    675 
    676 Some BFD functions want to print messages describing the problem.  They
    677 call a BFD error handler function.  This function may be overridden by
    678 the program.
    679 
    680    The BFD error handler acts like printf.

    698    *Description*
    699 Set the program name to use when printing a BFD error.  This is printed
    700 before the error message followed by a colon and space.  The string
    701 must not be changed after it is passed to this function.

    757    *Description*
    758 Set the flag word in the BFD ABFD to the value FLAGS.
    759 
    760    Possible errors are:
    761    * `bfd_error_wrong_format' - The target bfd was not of object format.
    762 
    763    * `bfd_error_invalid_operation' - The target bfd was open for
    764      reading.
    765 
    766    * `bfd_error_invalid_operation' - The flag word contained a bit
    767      which was not applicable to the type of file.  E.g., an attempt
    768      was made to set the `D_PAGED' bit on a BFD format which does not
    769      support demand paging.

    771 2.3.1.5 `bfd_get_arch_size'
    772 ...........................
    773 
    774 *Synopsis*
    775      int bfd_get_arch_size (bfd *abfd);
    776    *Description*
    777 Returns the architecture address size, in bits, as determined by the
    778 object file's format.  For ELF, this information is included in the
    779 header.
    780 
    781    *Returns*
    782 Returns the arch size in bits if known, `-1' otherwise.

    787 *Synopsis*
    788      int bfd_get_sign_extend_vma (bfd *abfd);
    789    *Description*
    790 Indicates if the target architecture "naturally" sign extends an
    791 address.  Some architectures implicitly sign extend address values when
    792 they are converted to types larger than the size of an address.  For
    793 instance, bfd_get_start_address() will return an address sign extended
    794 to fill a bfd_vma when this is the case.
    795 
    796    *Returns*
    797 Returns `1' if the target architecture is known to sign extend
    798 addresses, `0' if the target architecture is known to not sign extend
    799 addresses, and `-1' otherwise.

    836      bfd_vma bfd_scan_vma (const char *string, const char **end, int base);
    837    *Description*
    838 Convert, like `strtoul', a numerical expression STRING into a `bfd_vma'
    839 integer, and return that integer.  (Though without as many bells and
    840 whistles as `strtoul'.)  The expression is assumed to be unsigned
    841 (i.e., positive).  If given a BASE, it is used as the base for
    842 conversion.  A base of 0 causes the function to interpret the string in
    843 hex if a leading "0x" or "0X" is found, otherwise in octal if a leading
    844 zero is found, otherwise in decimal.
    845 
    846    If the value would overflow, the maximum `bfd_vma' value is returned.

   1036    *Description*
   1037 When testing an object for compatibility with a particular target
   1038 back-end, the back-end object_p function needs to set up certain fields
   1039 in the bfd on successfully recognizing the object.  This typically
   1040 happens in a piecemeal fashion, with failures possible at many points.
   1041 On failure, the bfd is supposed to be restored to its initial state,
   1042 which is virtually impossible.  However, restoring a subset of the bfd
   1043 state works in practice.  This function stores the subset and
   1044 reinitializes the bfd.

   1052 This function restores bfd state saved by bfd_preserve_save.  If MARKER
   1053 is non-NULL in struct bfd_preserve then that block and all subsequently
   1054 bfd_alloc'd memory is freed.

   1062 This function should be called when the bfd state saved by
   1063 bfd_preserve_save is no longer needed.  ie. when the back-end object_p
   1064 function returns with success.

   1165    *Description*
   1166 Return the file size (as read from file system) for the file associated
   1167 with BFD ABFD.
   1168 
   1169    The initial motivation for, and use of, this routine is not so we
   1170 can get the exact size of the object the BFD applies to, since that
   1171 might not be generally possible (archive members for example).  It
   1172 would be ideal if someone could eventually modify it so that such
   1173 results were guaranteed.
   1174 
   1175    Instead, we want to ask questions like "is this NNN byte sized
   1176 object I'm about to try read from file offset YYY reasonable?"  As as
   1177 example of where we might do this, some object formats use string
   1178 tables for which the first `sizeof (long)' bytes of the table contain
   1179 the size of the table itself, including the size bytes.  If an
   1180 application tries to read what it thinks is one of these string tables,
   1181 without some way to validate the size, and for some reason the size is
   1182 wrong (byte swapping error, wrong location for the string table, etc.),
   1183 the only clue is likely to be a read error when it tries to read the
   1184 table, or a "virtual memory exhausted" error when it tries to allocate
   1185 15 bazillon bytes of space for the 15 bazillon byte table it is about
   1186 to read.  This function at least allows us to answer the question, "is
   1187 the size reasonable?".

   1219 2.4 Memory Usage
   1220 ================
   1221 
   1222 BFD keeps all of its internal structures in obstacks. There is one
   1223 obstack per open BFD file, into which the current state is stored. When
   1224 a BFD is closed, the obstack is deleted, and so everything which has
   1225 been allocated by BFD for the closing file is thrown away.
   1226 
   1227    BFD does not free anything created by an application, but pointers
   1228 into `bfd' structures become invalid on a `bfd_close'; for example,
   1229 after a `bfd_close' the vector passed to `bfd_canonicalize_symtab' is
   1230 still around, since it has been allocated by the application, but the
   1231 data that it pointed to are lost.
   1232 
   1233    The general rule is to not close a BFD until all operations dependent
   1234 upon data from the BFD have been completed, or all the data from within
   1235 the file has been copied. To help with the management of memory, there
   1236 is a function (`bfd_alloc_size') which returns the number of bytes in
   1237 obstacks associated with the supplied BFD. This could be used to select
   1238 the greediest open BFD, close it to reclaim the memory, perform some
   1239 operation and reopen the BFD again, to get a fresh copy of the data
   1240 structures.

   1266 ============
   1267 
   1268 The raw data contained within a BFD is maintained through the section
   1269 abstraction.  A single BFD may have any number of sections.  It keeps
   1270 hold of them by pointing to the first; each one points to the next in
   1271 the list.
   1272 
   1273    Sections are supported in BFD in `section.c'.

   1284 
   1285 2.6.1 Section input
   1286 -------------------
   1287 
   1288 When a BFD is opened for reading, the section structures are created
   1289 and attached to the BFD.
   1290 
   1291    Each section has a name which describes the section in the outside
   1292 world--for example, `a.out' would contain at least three sections,
   1293 called `.text', `.data' and `.bss'.
   1294 
   1295    Names need not be unique; for example a COFF file may have several
   1296 sections named `.data'.
   1297 
   1298    Sometimes a BFD will contain more than the "natural" number of
   1299 sections. A back end may attach other sections containing constructor
   1300 data, or an application may add a section (using `bfd_make_section') to
   1301 the sections attached to an already open BFD. For example, the linker
   1302 creates an extra section `COMMON' for each input file's BFD to hold
   1303 information about common storage.
   1304 
   1305    The raw data is not necessarily read in when the section descriptor
   1306 is created. Some targets may leave the data in place until a
   1307 `bfd_get_section_contents' call is made. Other back ends may read in
   1308 all the data at once.  For example, an S-record file has to be read
   1309 once to determine the size of the data. An IEEE-695 file doesn't
   1310 contain raw data in sections, but data and relocation expressions
   1311 intermixed, so the data area has to be parsed to get out the data and
   1312 relocations.
   1313 
   1314

   1316 
   1317 2.6.2 Section output
   1318 --------------------
   1319 
   1320 To write a new object style BFD, the various sections to be written
   1321 have to be created. They are attached to the BFD in the same way as
   1322 input sections; data is written to the sections using
   1323 `bfd_set_section_contents'.
   1324 
   1325    Any program that creates or combines sections (e.g., the assembler
   1326 and linker) must use the `asection' fields `output_section' and
   1327 `output_offset' to indicate the file sections to which each section
   1328 must be written.  (If the section is being created from scratch,
   1329 `output_section' should probably point to the section itself and
   1330 `output_offset' should probably be zero.)
   1331 
   1332    The data to be written comes from input sections attached (via
   1333 `output_section' pointers) to the output sections.  The output section
   1334 structure can be considered a filter for the input section: the output
   1335 section determines the vma of the output data and the name, but the
   1336 input section determines the offset into the output section of the data
   1337 to be written.
   1338 
   1339    E.g., to create a section "O", starting at 0x100, 0x123 long,
   1340 containing two subsections, "A" at offset 0x0 (i.e., at vma 0x100) and
   1341 "B" at offset 0x20 (i.e., at vma 0x120) the `asection' structures would
   1342 look like:
   1343 
   1344         section name          "A"
   1345           output_offset   0x00
   1346           size            0x20
   1347           output_section ----------->  section name    "O"
   1348                                   |    vma             0x100
   1349         section name          "B" |    size            0x123
   1350           output_offset   0x20    |
   1351           size            0x103   |
   1352           output_section  --------|
   1353 
   1354 2.6.3 Link orders
   1355 -----------------
   1356 
   1357 The data within a section is stored in a "link_order".  These are much
   1358 like the fixups in `gas'.  The link_order abstraction allows a section
   1359 to grow and shrink within itself.
   1360 
   1361    A link_order knows how big it is, and which is the next link_order
   1362 and where the raw data for it is; it also points to a list of
   1363 relocations which apply to it.
   1364 
   1365    The link_order is used by the linker to perform relaxing on final
   1366 code.  The compiler creates code which is as big as necessary to make
   1367 it work without relaxing, and the user can select whether to relax.
   1368 Sometimes relaxing takes a lot of time.  The linker runs around the
   1369 relocations to see if any are attached to data which can be shrunk, if
   1370 so it does it on a link_order by link_order basis.

   1948      asection *bfd_get_section_by_name (bfd *abfd, const char *name);
   1949    *Description*
   1950 Run through ABFD and return the one of the `asection's whose name
   1951 matches NAME, otherwise `NULL'.  *Note Sections::, for more information.
   1952 
   1953    This should only be used in special cases; the normal way to process
   1954 all sections of a given name is to use `bfd_map_over_sections' and
   1955 `strcmp' on the name (or better yet, base it on the section flags or
   1956 something else) for each section.

   1967    *Description*
   1968 Call the provided function FUNC for each section attached to the BFD
   1969 ABFD whose name matches NAME, passing OBJ as an argument. The function
   1970 will be called as if by
   1971 
   1972             func (abfd, the_section, obj);
   1973 
   1974    It returns the first section for which FUNC returns true, otherwise
   1975 `NULL'.

   1982         (bfd *abfd, const char *templat, int *count);
   1983    *Description*
   1984 Invent a section name that is unique in ABFD by tacking a dot and a
   1985 digit suffix onto the original TEMPLAT.  If COUNT is non-NULL, then it
   1986 specifies the first number tried as a suffix to generate a unique name.
   1987 The value pointed to by COUNT will be incremented in this case.

   2228 2.7 Symbols
   2229 ===========
   2230 
   2231 BFD tries to maintain as much symbol information as it can when it
   2232 moves information from file to file. BFD passes information to
   2233 applications though the `asymbol' structure. When the application
   2234 requests the symbol table, BFD reads the table in the native form and
   2235 translates parts of it into the internal format. To maintain more than
   2236 the information passed to applications, some targets keep some
   2237 information "behind the scenes" in a structure only the particular back
   2238 end knows about. For example, the coff back end keeps the original
   2239 symbol table structure as well as the canonical structure when a BFD is
   2240 read in. On output, the coff back end can reconstruct the output symbol
   2241 table so that no information is lost, even information unique to coff
   2242 which BFD doesn't know or understand. If a coff symbol table were read,
   2243 but were written through an a.out back end, all the coff specific
   2244 information would be lost. The symbol table of a BFD is not necessarily
   2245 read in until a canonicalize request is made. Then the BFD back end
   2246 fills in a table provided by the application with pointers to the
   2247 canonical information.  To output symbols, the application provides BFD
   2248 with a table of pointers to pointers to `asymbol's. This allows
   2249 applications like the linker to output a symbol as it was read, since
   2250 the "behind the scenes" information will be still available.

   2263 2.7.1 Reading symbols
   2264 ---------------------
   2265 
   2266 There are two stages to reading a symbol table from a BFD: allocating
   2267 storage, and the actual reading process. This is an excerpt from an
   2268 application which reads the symbol table:
   2269 
   2270               long storage_needed;
   2271               asymbol **symbol_table;
   2272               long number_of_symbols;
   2273               long i;
   2274 
   2275               storage_needed = bfd_get_symtab_upper_bound (abfd);
   2276 
   2277               if (storage_needed < 0)
   2278                 FAIL
   2279 
   2280               if (storage_needed == 0)
   2281                 return;
   2282 
   2283               symbol_table = xmalloc (storage_needed);
   2284                 ...
   2285               number_of_symbols =
   2286                  bfd_canonicalize_symtab (abfd, symbol_table);
   2287 
   2288               if (number_of_symbols < 0)
   2289                 FAIL
   2290 
   2291               for (i = 0; i < number_of_symbols; i++)
   2292                 process_symbol (symbol_table[i]);
   2293 
   2294    All storage for the symbols themselves is in an objalloc connected
   2295 to the BFD; it is freed when the BFD is closed.

   2300 2.7.2 Writing symbols
   2301 ---------------------
   2302 
   2303 Writing of a symbol table is automatic when a BFD open for writing is
   2304 closed. The application attaches a vector of pointers to pointers to
   2305 symbols to the BFD being written, and fills in the symbol count. The
   2306 close and cleanup code reads through the table provided and performs
   2307 all the necessary operations. The BFD output code must always be
   2308 provided with an "owned" symbol: one which has come from another BFD,
   2309 or one which has been created using `bfd_make_empty_symbol'.  Here is an
   2310 example showing the creation of a symbol table with only one element:
   2311 
   2312             #include "bfd.h"
   2313             int main (void)
   2314             {
   2315               bfd *abfd;
   2316               asymbol *ptrs[2];
   2317               asymbol *new;
   2318 
   2319               abfd = bfd_openw ("foo","a.out-sunos-big");
   2320               bfd_set_format (abfd, bfd_object);
   2321               new = bfd_make_empty_symbol (abfd);
   2322               new->name = "dummy_symbol";
   2323               new->section = bfd_make_section_old_way (abfd, ".text");
   2324               new->flags = BSF_GLOBAL;
   2325               new->value = 0x12345;
   2326 
   2327               ptrs[0] = new;
   2328               ptrs[1] = 0;
   2329 
   2330               bfd_set_symtab (abfd, ptrs, 1);
   2331               bfd_close (abfd);
   2332               return 0;
   2333             }
   2334 
   2335             ./makesym
   2336             nm foo
   2337             00012345 A dummy_symbol
   2338 
   2339    Many formats cannot represent arbitrary symbol information; for
   2340 instance, the `a.out' object format does not allow an arbitrary number
   2341 of sections. A symbol pointing to a section which is not one  of
   2342 `.text', `.data' or `.bss' cannot be described.

   2347 2.7.3 Mini Symbols
   2348 ------------------
   2349 
   2350 Mini symbols provide read-only access to the symbol table.  They use
   2351 less memory space, but require more time to access.  They can be useful
   2352 for tools like nm or objdump, which may have to handle symbol tables of
   2353 extremely large executables.
   2354 
   2355    The `bfd_read_minisymbols' function will read the symbols into
   2356 memory in an internal form.  It will return a `void *' pointer to a
   2357 block of memory, a symbol count, and the size of each symbol.  The
   2358 pointer is allocated using `malloc', and should be freed by the caller
   2359 when it is no longer needed.
   2360 
   2361    The function `bfd_minisymbol_to_symbol' will take a pointer to a
   2362 minisymbol, and a pointer to a structure returned by
   2363 `bfd_make_empty_symbol', and return a `asymbol' structure.  The return
   2364 value may or may not be the same as the value from
   2365 `bfd_make_empty_symbol' which was passed in.

   2370 2.7.4 typedef asymbol
   2371 ---------------------
   2372 
   2373 An `asymbol' has the form:
   2374 
   2375 
   2376      typedef struct bfd_symbol
   2377      {
   2378        /* A pointer to the BFD which owns the symbol. This information
   2379           is necessary so that a back end can work out what additional
   2380           information (invisible to the application writer) is carried
   2381           with the symbol.
   2382 
   2383           This field is *almost* redundant, since you can use section->owner
   2384           instead, except that some symbols point to the global sections

   2680 2.8 Archives
   2681 ============
   2682 
   2683 *Description*
   2684 An archive (or library) is just another BFD.  It has a symbol table,
   2685 although there's not much a user program will do with it.
   2686 
   2687    The big difference between an archive BFD and an ordinary BFD is
   2688 that the archive doesn't have sections.  Instead it has a chain of BFDs
   2689 that are considered its contents.  These BFDs can be manipulated like
   2690 any other.  The BFDs contained in an archive opened for reading will
   2691 all be opened for reading.  You may put either input or output BFDs
   2692 into an archive opened for output; they will be handled correctly when
   2693 the archive is closed.
   2694 
   2695    Use `bfd_openr_next_archived_file' to step through the contents of
   2696 an archive opened for input.  You don't have to read the entire archive
   2697 if you don't want to!  Read it until you find what you want.
   2698 
   2699    Archive contents of output BFDs are chained through the `next'
   2700 pointer in a BFD.  The first one is findable through the `archive_head'
   2701 slot of the archive.  Set it with `bfd_set_archive_head' (q.v.).  A
   2702 given BFD may be in only one open output archive at a time.
   2703 
   2704    As expected, the BFD archive code is more general than the archive
   2705 code of any given environment.  BFD archives may contain files of
   2706 different formats (e.g., a.out and coff) and even different
   2707 architectures.  You may even place archives recursively into archives!
   2708 
   2709    This can cause unexpected confusion, since some archive formats are
   2710 more expressive than others.  For instance, Intel COFF archives can
   2711 preserve long filenames; SunOS a.out archives cannot.  If you move a
   2712 file from the first to the second format and back again, the filename
   2713 may be truncated.  Likewise, different a.out environments have different
   2714 conventions as to how they truncate filenames, whether they preserve
   2715 directory names in filenames, etc.  When interoperating with native
   2716 tools, be sure your files are homogeneous.
   2717 
   2718    Beware: most of these formats do not react well to the presence of
   2719 spaces in filenames.  We do the best we can, but can't always handle
   2720 this case due to restrictions in the format of archives.  Many Unix
   2721 utilities are braindead in regards to spaces and such in filenames
   2722 anyway, so this shouldn't be much of a restriction.
   2723 
   2724    Archives are supported in BFD in `archive.c'.

   2742

   2761 Provided a BFD, ARCHIVE, containing an archive and NULL, open an input
   2762 BFD on the first contained element and returns that.  Subsequent calls
   2763 should pass the archive and the previous return value to return a
   2764 created BFD to the next contained element. NULL is returned when there
   2765 are no more.

   2770 2.9 File formats
   2771 ================
   2772 
   2773 A format is a BFD concept of high level file contents type. The formats
   2774 supported by BFD are:
   2775 
   2776    * `bfd_object'
   2777    The BFD may contain data, symbols, relocations and debug info.
   2778 
   2779    * `bfd_archive'
   2780    The BFD contains other BFDs and an optional index.
   2781 
   2782    * `bfd_core'
   2783    The BFD contains the result of an executable core dump.
   2784 
   2785 2.9.1 File format functions
   2786 ---------------------------
   2787 
   2788 2.9.1.1 `bfd_check_format'
   2789 ..........................
   2790 
   2791 *Synopsis*
   2792      bfd_boolean bfd_check_format (bfd *abfd, bfd_format format);
   2793    *Description*
   2794 Verify if the file attached to the BFD ABFD is compatible with the
   2795 format FORMAT (i.e., one of `bfd_object', `bfd_archive' or `bfd_core').
   2796 
   2797    If the BFD has been set to a specific target before the call, only
   2798 the named target and format combination is checked. If the target has
   2799 not been set, or has been set to `default', then all the known target
   2800 backends is interrogated to determine a match.  If the default target
   2801 matches, it is used.  If not, exactly one target must recognize the
   2802 file, or an error results.
   2803 
   2804    The function returns `TRUE' on success, otherwise `FALSE' with one
   2805 of the following error codes:
   2806 
   2807    * `bfd_error_invalid_operation' - if `format' is not one of
   2808      `bfd_object', `bfd_archive' or `bfd_core'.
   2809 
   2810    * `bfd_error_system_call' - if an error occured during a read - even
   2811      some file mismatches can cause bfd_error_system_calls.
   2812 
   2813    * `file_not_recognised' - none of the backends recognised the file
   2814      format.
   2815 
   2816    * `bfd_error_file_ambiguously_recognized' - more than one backend
   2817      recognised the file format.
   2818 
   2819 2.9.1.2 `bfd_check_format_matches'
   2820 ..................................
   2821

   2823      bfd_boolean bfd_check_format_matches
   2824         (bfd *abfd, bfd_format format, char ***matching);
   2825    *Description*
   2826 Like `bfd_check_format', except when it returns FALSE with `bfd_errno'
   2827 set to `bfd_error_file_ambiguously_recognized'.  In that case, if
   2828 MATCHING is not NULL, it will be filled in with a NULL-terminated list
   2829 of the names of the formats that matched, allocated with `malloc'.
   2830 Then the user may choose a format and try again.
   2831 
   2832    When done with the list that MATCHING points to, the caller should
   2833 free it.
   2834 
   2835 2.9.1.3 `bfd_set_format'
   2836 ........................
   2837 
   2838 *Synopsis*
   2839      bfd_boolean bfd_set_format (bfd *abfd, bfd_format format);
   2840    *Description*
   2841 This function sets the file format of the BFD ABFD to the format
   2842 FORMAT. If the target set in the BFD does not support the format
   2843 requested, the format is invalid, or the BFD is not open for writing,
   2844 then an error occurs.
   2845 
   2846 2.9.1.4 `bfd_format_string'
   2847 ...........................
   2848 
   2849 *Synopsis*
   2850      const char *bfd_format_string (bfd_format format);
   2851    *Description*
   2852 Return a pointer to a const string `invalid', `object', `archive',
   2853 `core', or `unknown', depending upon the value of FORMAT.

   2858 2.10 Relocations
   2859 ================
   2860 
   2861 BFD maintains relocations in much the same way it maintains symbols:
   2862 they are left alone until required, then read in en-masse and
   2863 translated into an internal form.  A common routine
   2864 `bfd_perform_relocation' acts upon the canonical form to do the fixup.
   2865 
   2866    Relocations are maintained on a per section basis, while symbols are
   2867 maintained on a per BFD basis.
   2868 
   2869    All that a back end has to do to fit the BFD interface is to create
   2870 a `struct reloc_cache_entry' for each relocation in a particular
   2871 section, and fill in the right bits of the structures.

   2932 
   2933      }
   2934      arelent;
   2935    *Description*
   2936 Here is a description of each of the fields within an `arelent':
   2937 
   2938    * `sym_ptr_ptr'
   2939    The symbol table pointer points to a pointer to the symbol
   2940 associated with the relocation request.  It is the pointer into the
   2941 table returned by the back end's `canonicalize_symtab' action. *Note
   2942 Symbols::. The symbol is referenced through a pointer to a pointer so
   2943 that tools like the linker can fix up all the symbols of the same name
   2944 by modifying only one pointer. The relocation routine looks in the
   2945 symbol and uses the base of the section the symbol is attached to and
   2946 the value of the symbol as the initial relocation offset. If the symbol
   2947 pointer is zero, then the section provided is looked up.
   2948 
   2949    * `address'
   2950    The `address' field gives the offset in bytes from the base of the
   2951 section data which owns the relocation record to the first byte of
   2952 relocatable information. The actual data relocated will be relative to
   2953 this point; for example, a relocation type which modifies the bottom
   2954 two bytes of a four byte word would not touch the first byte pointed to
   2955 in a big endian world.
   2956 
   2957    * `addend'
   2958    The `addend' is a value provided by the back end to be added (!)  to
   2959 the relocation offset. Its interpretation is dependent upon the howto.
   2960 For example, on the 68k the code:
   2961 
   2962              char foo[];
   2963              main()
   2964                      {
   2965                      return foo[0x12345678];
   2966                      }
   2967 
   2968    Could be compiled into:
   2969 
   2970              linkw fp,#-4
   2971              moveb @#12345678,d0
   2972              extbl d0
   2973              unlk fp
   2974              rts
   2975 
   2976    This could create a reloc pointing to `foo', but leave the offset in
   2977 the data, something like:
   2978 
   2979      RELOCATION RECORDS FOR [.text]:
   2980      offset   type      value
   2981      00000006 32        _foo
   2982 
   2983      00000000 4e56 fffc          ; linkw fp,#-4
   2984      00000004 1039 1234 5678     ; moveb @#12345678,d0
   2985      0000000a 49c0               ; extbl d0
   2986      0000000c 4e5e               ; unlk fp
   2987      0000000e 4e75               ; rts
   2988 
   2989    Using coff and an 88k, some instructions don't have enough space in
   2990 them to represent the full address range, and pointers have to be
   2991 loaded in two parts. So you'd get something like:
   2992 
   2993              or.u     r13,r0,hi16(_foo+0x12345678)
   2994              ld.b     r2,r13,lo16(_foo+0x12345678)
   2995              jmp      r1
   2996 
   2997    This should create two relocs, both pointing to `_foo', and with
   2998 0x12340000 in their addend field. The data would consist of:
   2999 
   3000      RELOCATION RECORDS FOR [.text]:
   3001      offset   type      value
   3002      00000002 HVRT16    _foo+0x12340000
   3003      00000006 LVRT16    _foo+0x12340000
   3004 
   3005      00000000 5da05678           ; or.u r13,r0,0x5678
   3006      00000004 1c4d5678           ; ld.b r2,r13,0x5678
   3007      00000008 f400c001           ; jmp r1
   3008 
   3009    The relocation routine digs out the value from the data, adds it to
   3010 the addend to get the original offset, and then adds the value of
   3011 `_foo'. Note that all 32 bits have to be kept around somewhere, to cope
   3012 with carry from bit 15 to bit 16.
   3013 
   3014    One further example is the sparc and the a.out format. The sparc has
   3015 a similar problem to the 88k, in that some instructions don't have room
   3016 for an entire offset, but on the sparc the parts are created in odd
   3017 sized lumps. The designers of the a.out format chose to not use the
   3018 data within the section for storing part of the offset; all the offset
   3019 is kept within the reloc. Anything in the data should be ignored.
   3020 
   3021              save %sp,-112,%sp
   3022              sethi %hi(_foo+0x12345678),%g2
   3023              ldsb [%g2+%lo(_foo+0x12345678)],%i0
   3024              ret
   3025              restore
   3026 
   3027    Both relocs contain a pointer to `foo', and the offsets contain junk.
   3028 
   3029      RELOCATION RECORDS FOR [.text]:
   3030      offset   type      value
   3031      00000004 HI22      _foo+0x12345678
   3032      00000008 LO10      _foo+0x12345678
   3033 
   3034      00000000 9de3bf90     ; save %sp,-112,%sp
   3035      00000004 05000000     ; sethi %hi(_foo+0),%g2
   3036      00000008 f048a000     ; ldsb [%g2+%lo(_foo+0)],%i0
   3037      0000000c 81c7e008     ; ret
   3038      00000010 81e80000     ; restore
   3039 
   3040    * `howto'
   3041    The `howto' field can be imagined as a relocation instruction. It is
   3042 a pointer to a structure which contains information on what to do with
   3043 all of the other information in the reloc record and data section. A
   3044 back end would normally have a relocation instruction set and turn
   3045 relocations into pointers to the correct structure on input - but it
   3046 would be possible to create each howto field on demand.

   3253    *Description*
   3254 If OUTPUT_BFD is supplied to this function, the generated image will be
   3255 relocatable; the relocations are copied to the output file after they
   3256 have been changed to reflect the new state of the world. There are two
   3257 ways of reflecting the results of partial linkage in an output file: by
   3258 modifying the output data in place, and by modifying the relocation
   3259 record.  Some native formats (e.g., basic a.out and basic coff) have no
   3260 way of specifying an addend in the relocation type, so the addend has
   3261 to go in the output data.  This is no big deal since in these formats
   3262 the output data slot will always be big enough for the addend. Complex
   3263 reloc types with addends were invented to solve just this problem.  The
   3264 ERROR_MESSAGE argument is set to an error message if this return
   3265 `bfd_reloc_dangerous'.

   3288 2.10.2 The howto manager
   3289 ------------------------
   3290 
   3291 When an application wants to create a relocation, but doesn't know what
   3292 the target machine might call it, it can find out by using this bit of
   3293 code.

   3298 *Description*
   3299 The insides of a reloc code.  The idea is that, eventually, there will
   3300 be one enumerator for every type of relocation we ever do.  Pass one of
   3301 these values to `bfd_reloc_type_lookup', and it'll return a howto
   3302 pointer.
   3303 
   3304    This does mean that the application must determine the correct
   3305 enumerator value; you can't get a howto pointer from a random set of
   3306 attributes.

   3518  -- : BFD_RELOC_ALPHA_GPDISP_HI16
   3519      Alpha ECOFF and ELF relocations.  Some of these treat the symbol or
   3520      "addend" in some special way.  For GPDISP_HI16 ("gpdisp")
   3521      relocations, the symbol is ignored when writing; when reading, it
   3522      will be the absolute section symbol.  The addend is the
   3523      displacement in bytes of the "lda" instruction from the "ldah"
   3524      instruction (which is at the address of this reloc).
   3525 
   3526  -- : BFD_RELOC_ALPHA_GPDISP_LO16
   3527      For GPDISP_LO16 ("ignore") relocations, the symbol is handled as
   3528      with GPDISP_HI16 relocs.  The addend is ignored when writing the
   3529      relocations out, and is filled in with the file's GP value on
   3530      reading, for convenience.
   3531 
   3532  -- : BFD_RELOC_ALPHA_GPDISP
   3533      The ELF GPDISP relocation is exactly the same as the GPDISP_HI16
   3534      relocation except that there is no accompanying GPDISP_LO16
   3535      relocation.
   3536 
   3537  -- : BFD_RELOC_ALPHA_LITERAL
   3538  -- : BFD_RELOC_ALPHA_ELF_LITERAL
   3539  -- : BFD_RELOC_ALPHA_LITUSE
   3540      The Alpha LITERAL/LITUSE relocs are produced by a symbol reference;
   3541      the assembler turns it into a LDQ instruction to load the address
   3542      of the symbol, and then fills in a register in the real
   3543      instruction.
   3544 
   3545      The LITERAL reloc, at the LDQ instruction, refers to the .lita
   3546      section symbol.  The addend is ignored when writing, but is filled
   3547      in with the file's GP value on reading, for convenience, as with
   3548      the GPDISP_LO16 reloc.
   3549 
   3550      The ELF_LITERAL reloc is somewhere between 16_GOTOFF and
   3551      GPDISP_LO16.  It should refer to the symbol to be referenced, as
   3552      with 16_GOTOFF, but it generates output not based on the position
   3553      within the .got section, but relative to the GP value chosen for
   3554      the file during the final link stage.
   3555 
   3556      The LITUSE reloc, on the instruction using the loaded address,
   3557      gives information to the linker that it might be able to use to
   3558      optimize away some literal section references.  The symbol is
   3559      ignored (read as the absolute section symbol), and the "addend"
   3560      indicates the type of instruction using the register: 1 - "memory"
   3561      fmt insn 2 - byte-manipulation (byte offset reg) 3 - jsr (target
   3562      of branch)
   3563 
   3564  -- : BFD_RELOC_ALPHA_HINT
   3565      The HINT relocation indicates a value that should be filled into
   3566      the "hint" field of a jmp/jsr/ret instruction, for possible branch-
   3567      prediction logic which may be provided on some processors.
   3568 
   3569  -- : BFD_RELOC_ALPHA_LINKAGE
   3570      The LINKAGE relocation outputs a linkage pair in the object file,
   3571      which is filled by the linker.
   3572 
   3573  -- : BFD_RELOC_ALPHA_CODEADDR
   3574      The CODEADDR relocation outputs a STO_CA in the object file, which
   3575      is filled by the linker.
   3576 
   3577  -- : BFD_RELOC_ALPHA_GPREL_HI16
   3578  -- : BFD_RELOC_ALPHA_GPREL_LO16
   3579      The GPREL_HI/LO relocations together form a 32-bit offset from the
   3580      GP register.

   3582  -- : BFD_RELOC_ALPHA_BRSGP
   3583      Like BFD_RELOC_23_PCREL_S2, except that the source and target must

   3585      STO_ALPHA_STD_GPLOAD.
   3586 
   3587  -- : BFD_RELOC_ALPHA_NOP
   3588      The NOP relocation outputs a NOP if the longword displacement

   3591  -- : BFD_RELOC_ALPHA_BSR

   5102      These two relocations are used by the linker to determine which of
   5103      the entries in a C++ virtual function table are actually used.
   5104      When the -gc-sections option is given, the linker will zero out
   5105      the entries that are not used, so that the code for those
   5106      functions need not be included in the output.
   5107 
   5108      VTABLE_INHERIT is a zero-space relocation used to describe to the
   5109      linker the inheritance tree of a C++ virtual function table.  The
   5110      relocation's symbol should be the parent class' vtable, and the
   5111      relocation should be located at the child vtable.
   5112 
   5113      VTABLE_ENTRY is a zero-space relocation that describes the use of a
   5114      virtual function table entry.  The reloc's symbol should refer to
   5115      the table of the class mentioned in the code.  Off of that base,
   5116      an offset describes the entry that is being used.  For Rela hosts,
   5117      this offset is stored in the reloc's addend.  For Rel hosts, we
   5118      are forced to put this offset in the reloc's section offset.

   5535      number is encoded in the relocation.  The relocation applies to the
   5536      last PC-relative immediate operand, or if there are no PC-relative
   5537      immediates, to the last immediate operand.

   5842 ============
   5843 
   5844 *Description*
   5845 Each port of BFD to a different machine requires the creation of a
   5846 target back end. All the back end provides to the root part of BFD is a
   5847 structure containing pointers to functions which perform certain low
   5848 level operations on files. BFD translates the applications's requests
   5849 through a pointer into calls to the back end routines.
   5850 
   5851    When a file is opened with `bfd_openr', its format and target are
   5852 unknown. BFD uses various mechanisms to determine how to interpret the
   5853 file. The operations performed are:
   5854 
   5855    * Create a BFD by calling the internal routine `_bfd_new_bfd', then
   5856      call `bfd_find_target' with the target string supplied to
   5857      `bfd_openr' and the new BFD pointer.
   5858 
   5859    * If a null target string was provided to `bfd_find_target', look up
   5860      the environment variable `GNUTARGET' and use that as the target
   5861      string.
   5862 
   5863    * If the target string is still `NULL', or the target string is
   5864      `default', then use the first item in the target vector as the
   5865      target type, and set `target_defaulted' in the BFD to cause
   5866      `bfd_check_format' to loop through all the targets.  *Note
   5867      bfd_target::.  *Note Formats::.
   5868 
   5869    * Otherwise, inspect the elements in the target vector one by one,
   5870      until a match on target name is found. When found, use it.
   5871 
   5872    * Otherwise return the error `bfd_error_invalid_target' to
   5873      `bfd_openr'.
   5874 
   5875    * `bfd_openr' attempts to open the file using `bfd_open_file', and
   5876      returns the BFD.
   5877    Once the BFD has been opened and the target selected, the file
   5878 format may be determined. This is done by calling `bfd_check_format' on
   5879 the BFD with a suggested format.  If `target_defaulted' has been set,
   5880 each possible target type is tried to see if it recognizes the
   5881 specified format.  `bfd_check_format' returns `TRUE' when the caller
   5882 guesses right.

   5892 -----------------
   5893 
   5894 *Description*
   5895 This structure contains everything that BFD knows about a target. It
   5896 includes things like its byte order, name, and which routines to call
   5897 to do various operations.
   5898 
   5899    Every BFD points to a target structure with its `xvec' member.
   5900 
   5901    The macros below are used to dispatch to functions through the
   5902 `bfd_target' vector. They are used in a number of macros further down
   5903 in `bfd.h', and are also used when calling various routines by hand
   5904 inside the BFD implementation.  The ARGLIST argument must be
   5905 parenthesized; it contains all the arguments to the called function.
   5906 
   5907    They make the documentation (more) unpleasant to read, so if someone
   5908 wants to fix this and not break the above, please do.

   5931 `xvec' member of the struct `bfd' itself points here.  Each module that

   5935 entry points which call them. Too bad we can't have one macro to define

   6411 2.13 Architectures
   6412 ==================
   6413 
   6414 BFD keeps one atom in a BFD describing the architecture of the data
   6415 attached to the BFD: a pointer to a `bfd_arch_info_type'.
   6416 
   6417    Pointers to structures can be requested independently of a BFD so
   6418 that an architecture's information can be interrogated without access
   6419 to an open BFD.
   6420 
   6421    The architecture information is provided by each architecture
   6422 package.  The set of default architectures is selected by the macro
   6423 `SELECT_ARCHITECTURES'.  This is normally set up in the
   6424 `config/TARGET.mt' file of your choice.  If the name is not defined,
   6425 then all the architectures supported are included.
   6426 
   6427    When BFD starts up, all the architectures are called with an
   6428 initialize method.  It is up to the architecture back end to insert as
   6429 many items into the list of architectures as it wants to; generally
   6430 this would be one for each machine and one for the default case (an
   6431 item with a machine field of 0).
   6432 
   6433    BFD's idea of an architecture is implemented in `archures.c'.

   6440 sense--i.e., what processor family does it belong to?  Another field
   6441 indicates which processor within the family is in use.  The machine
   6442 gives a number which distinguishes different versions of the
   6443 architecture, containing, for example, 2 and 3 for Intel i960 KA and

   7037          const char *mode, int fd);
   7038    *Description*
   7039 Open the file FILENAME with the target TARGET.  Return a pointer to the
   7040 created BFD.  If FD is not -1, then `fdopen' is used to open the file;
   7041 otherwise, `fopen' is used.  MODE is passed directly to `fopen' or
   7042 `fdopen'.
   7043 
   7044    Calls `bfd_find_target', so TARGET is interpreted as by that
   7045 function.
   7046 
   7047    The new BFD is marked as cacheable iff FD is -1.
   7048 
   7049    If `NULL' is returned then an error has occured.   Possible errors
   7050 are `bfd_error_no_memory', `bfd_error_invalid_target' or `system_call'
   7051 error.
   7052

   7059 Open the file FILENAME (using `fopen') with the target TARGET.  Return
   7060 a pointer to the created BFD.
   7061 
   7062    Calls `bfd_find_target', so TARGET is interpreted as by that
   7063 function.
   7064 
   7065    If `NULL' is returned then an error has occured.   Possible errors
   7066 are `bfd_error_no_memory', `bfd_error_invalid_target' or `system_call'
   7067 error.
   7068

   7072 *Synopsis*
   7073      bfd *bfd_fdopenr (const char *filename, const char *target, int fd);
   7074    *Description*
   7075 `bfd_fdopenr' is to `bfd_fopenr' much like `fdopen' is to `fopen'.  It
   7076 opens a BFD on a file already described by the FD supplied.
   7077 
   7078    When the file is later `bfd_close'd, the file descriptor will be
   7079 closed.  If the caller desires that this file descriptor be cached by
   7080 BFD (opened as needed, closed as needed to free descriptors for other
   7081 opens), with the supplied FD used as an initial file descriptor (but
   7082 subject to closure at any time), call bfd_set_cacheable(bfd, 1) on the
   7083 returned BFD.  The default is to assume no caching; the file descriptor
   7084 will remain open until `bfd_close', and will not be affected by BFD
   7085 operations on other files.
   7086 
   7087    Possible errors are `bfd_error_no_memory',
   7088 `bfd_error_invalid_target' and `bfd_error_system_call'.

   7095    *Description*
   7096 Open a BFD for read access on an existing stdio stream.  When the BFD

   7117    *Description*
   7118 Create and return a BFD backed by a read-only STREAM.  The STREAM is
   7119 created using OPEN_FUNC, accessed using PREAD_FUNC and destroyed using
   7120 CLOSE_FUNC.
   7121 
   7122    Calls `bfd_find_target', so TARGET is interpreted as by that
   7123 function.
   7124 
   7125    Calls OPEN_FUNC (which can call `bfd_zalloc' and `bfd_get_filename')
   7126 to obtain the read-only stream backing the BFD.  OPEN_FUNC either
   7127 succeeds returning the non-`NULL' STREAM, or fails returning `NULL'
   7128 (setting `bfd_error').
   7129 
   7130    Calls PREAD_FUNC to request NBYTES of data from STREAM starting at
   7131 OFFSET (e.g., via a call to `bfd_read').  PREAD_FUNC either succeeds
   7132 returning the number of bytes read (which can be less than NBYTES when
   7133 end-of-file), or fails returning -1 (setting `bfd_error').
   7134 
   7135    Calls CLOSE_FUNC when the BFD is later closed using `bfd_close'.
   7136 CLOSE_FUNC either succeeds returning 0, or fails returning -1 (setting
   7137 `bfd_error').
   7138 
   7139    Calls STAT_FUNC to fill in a stat structure for bfd_stat,
   7140 bfd_get_size, and bfd_get_mtime calls.  STAT_FUNC returns 0 on success,
   7141 or returns -1 on failure (setting `bfd_error').
   7142 
   7143    If `bfd_openr_iovec' returns `NULL' then an error has occurred.
   7144 Possible errors are `bfd_error_no_memory', `bfd_error_invalid_target'
   7145 and `bfd_error_system_call'.

   7163      bfd_boolean bfd_close (bfd *abfd);
   7164    *Description*
   7165 Close a BFD. If the BFD was open for writing, then pending operations
   7166 are completed and the file written out and closed.  If the created file
   7167 is executable, then `chmod' is called to mark it as such.
   7168 
   7169    All memory attached to the BFD is released.
   7170 
   7171    The file descriptor associated with the BFD is closed (even if it
   7172 was passed in to BFD by `bfd_fdopenr').
   7173 
   7174    *Returns*

   7182    *Description*
   7183 Close a BFD.  Differs from `bfd_close' since it does not complete any
   7184 pending operations.  This routine would be used if the application had
   7185 just used BFD for swapping and didn't want to use any of the writing
   7186 code.
   7187 
   7188    If the created file is executable, then `chmod' is called to mark it
   7189 as such.
   7190 
   7191    All memory attached to the BFD is released.
   7192 
   7193    *Returns*

   7212 Takes a BFD as created by `bfd_create' and converts it into one like as
   7213 returned by `bfd_openw'.  It does this by converting the BFD to
   7214 BFD_IN_MEMORY.  It's assumed that you will call `bfd_make_readable' on
   7215 this bfd later.
   7216 
   7217    *Returns*
   7218 `TRUE' is returned if all is ok, otherwise `FALSE'.

   7226 Takes a BFD as created by `bfd_create' and `bfd_make_writable' and
   7227 converts it into one like as returned by `bfd_openr'.  It does this by
   7228 writing the contents out to the memory buffer, then reversing the
   7229 direction.

   7321 Takes a BFD and searches it for a .gnu_debuglink section.  If this
   7322 section is found, it examines the section for the name and checksum of
   7323 a '.debug' file containing auxiliary debugging information.  It then
   7324 searches the filesystem for this .debug file in some standard
   7325 locations, including the directory tree rooted at DIR, and if found
   7326 returns the full filename.
   7327 
   7328    If DIR is NULL, it will search a default path configured into libbfd
   7329 at build time.  [XXX this feature is not currently implemented].
   7330 
   7331    *Returns*
   7332 `NULL' on any errors or failure to locate the .debug file, otherwise a

   7391 .......................
   7392 
   7393 *Description*
   7394 These macros as used for reading and writing raw data in sections; each
   7395 access (except for bytes) is vectored through the target format of the
   7396 BFD and mangled accordingly. The mangling performs any necessary endian
   7397 translations and removes alignment restrictions.  Note that types
   7398 accepted and returned by these macros are identical so they can be
   7399 swapped around in macros--for example, `libaout.h' defines `GET_WORD'
   7400 to either `bfd_get_32' or `bfd_get_64'.
   7401 
   7402    In the put routines, VAL must be a `bfd_vma'.  If we are on a system
   7403 without prototypes, the caller is responsible for making sure that is
   7404 true, with a cast if necessary.  We don't cast them in the macro
   7405 definitions because that would prevent `lint' or `gcc -Wall' from
   7406 detecting sins such as passing a pointer.  To detect calling these with
   7407 less than a `bfd_vma', use `gcc -Wconversion' on a host with 64 bit
   7408 `bfd_vma''s.

   7542 =================
   7543 
   7544 The file caching mechanism is embedded within BFD and allows the
   7545 application to open as many BFDs as it wants without regard to the
   7546 underlying operating system's file descriptor limit (often as low as 20
   7547 open files).  The module in `cache.c' maintains a least recently used
   7548 list of `BFD_CACHE_MAX_OPEN' files, and exports the name
   7549 `bfd_cache_lookup', which runs around and makes sure that the required
   7550 BFD is open. If not, then it chooses a file to close, closes it and
   7551 opens the one wanted, returning its file handle.

   7605 2.17 Linker Functions
   7606 =====================
   7607 
   7608 The linker uses three special entry points in the BFD target vector.
   7609 It is not necessary to write special routines for these entry points
   7610 when creating a new BFD back end, since generic versions are provided.
   7611 However, writing them can speed up linking and make it use
   7612 significantly less runtime memory.
   7613 
   7614    The first routine creates a hash table used by the other routines.
   7615 The second routine adds the symbols from an object file to the hash
   7616 table.  The third routine takes all the object files and links them
   7617 together to create the output file.  These routines are designed so
   7618 that the linker proper does not need to know anything about the symbols
   7619 in the object files that it is linking.  The linker merely arranges the
   7620 sections as directed by the linker script and lets BFD handle the
   7621 details of symbols and relocs.
   7622 
   7623    The second routine and third routines are passed a pointer to a
   7624 `struct bfd_link_info' structure (defined in `bfdlink.h') which holds
   7625 information relevant to the link, including the linker hash table
   7626 (which was created by the first routine) and a set of callback
   7627 functions to the linker proper.
   7628 
   7629    The generic linker routines are in `linker.c', and use the header
   7630 file `genlink.h'.  As of this writing, the only back ends which have
   7631 implemented versions of these routines are a.out (in `aoutx.h') and
   7632 ECOFF (in `ecoff.c').  The a.out routines are used as examples
   7633 throughout this section.

   7643 
   7644 2.17.1 Creating a linker hash table
   7645 -----------------------------------
   7646 
   7647 The linker routines must create a hash table, which must be derived
   7648 from `struct bfd_link_hash_table' described in `bfdlink.c'.  *Note Hash
   7649 Tables::, for information on how to create a derived hash table.  This
   7650 entry point is called using the target vector of the linker output file.
   7651 
   7652    The `_bfd_link_hash_table_create' entry point must allocate and
   7653 initialize an instance of the desired hash table.  If the back end does
   7654 not require any additional information to be stored with the entries in
   7655 the hash table, the entry point may simply create a `struct
   7656 bfd_link_hash_table'.  Most likely, however, some additional
   7657 information will be needed.
   7658 
   7659    For example, with each entry in the hash table the a.out linker
   7660 keeps the index the symbol has in the final output file (this index
   7661 number is used so that when doing a relocatable link the symbol index
   7662 used in the output file can be quickly filled in when copying over a
   7663 reloc).  The a.out linker code defines the required structures and
   7664 functions for a hash table derived from `struct bfd_link_hash_table'.
   7665 The a.out linker hash table is created by the function
   7666 `NAME(aout,link_hash_table_create)'; it simply allocates space for the
   7667 hash table, initializes it, and returns a pointer to it.
   7668 
   7669    When writing the linker routines for a new back end, you will
   7670 generally not know exactly which fields will be required until you have
   7671 finished.  You should simply create a new hash table which defines no
   7672 additional fields, and then simply add fields as they become necessary.

   7677 2.17.2 Adding symbols to the hash table
   7678 ---------------------------------------
   7679 
   7680 The linker proper will call the `_bfd_link_add_symbols' entry point for
   7681 each object file or archive which is to be linked (typically these are
   7682 the files named on the command line, but some may also come from the
   7683 linker script).  The entry point is responsible for examining the file.
   7684 For an object file, BFD must add any relevant symbol information to the
   7685 hash table.  For an archive, BFD must determine which elements of the
   7686 archive should be used and adding them to the link.
   7687 
   7688    The a.out version of this entry point is
   7689 `NAME(aout,link_add_symbols)'.

   7700 2.17.2.1 Differing file formats
   7701 ...............................
   7702 
   7703 Normally all the files involved in a link will be of the same format,
   7704 but it is also possible to link together different format object files,
   7705 and the back end must support that.  The `_bfd_link_add_symbols' entry
   7706 point is called via the target vector of the file to be added.  This
   7707 has an important consequence: the function may not assume that the hash
   7708 table is the type created by the corresponding
   7709 `_bfd_link_hash_table_create' vector.  All the `_bfd_link_add_symbols'
   7710 function can assume about the hash table is that it is derived from
   7711 `struct bfd_link_hash_table'.
   7712 
   7713    Sometimes the `_bfd_link_add_symbols' function must store some
   7714 information in the hash table entry to be used by the `_bfd_final_link'
   7715 function.  In such a case the output bfd xvec must be checked to make
   7716 sure that the hash table was created by an object file of the same
   7717 format.
   7718 
   7719    The `_bfd_final_link' routine must be prepared to handle a hash
   7720 entry without any extra information added by the
   7721 `_bfd_link_add_symbols' function.  A hash entry without extra
   7722 information will also occur when the linker script directs the linker
   7723 to create a symbol.  Note that, regardless of how a hash table entry is
   7724 added, all the fields will be initialized to some sort of null value by
   7725 the hash table entry initialization function.
   7726 
   7727    See `ecoff_link_add_externals' for an example of how to check the
   7728 output bfd before saving information (in this case, the ECOFF external
   7729 symbol debugging information) in a hash table entry.

   7734 2.17.2.2 Adding symbols from an object file
   7735 ...........................................
   7736 
   7737 When the `_bfd_link_add_symbols' routine is passed an object file, it
   7738 must add all externally visible symbols in that object file to the hash
   7739 table.  The actual work of adding the symbol to the hash table is
   7740 normally handled by the function `_bfd_generic_link_add_one_symbol'.
   7741 The `_bfd_link_add_symbols' routine is responsible for reading all the
   7742 symbols from the object file and passing the correct information to
   7743 `_bfd_generic_link_add_one_symbol'.
   7744 
   7745    The `_bfd_link_add_symbols' routine should not use
   7746 `bfd_canonicalize_symtab' to read the symbols.  The point of providing
   7747 this routine is to avoid the overhead of converting the symbols into
   7748 generic `asymbol' structures.
   7749 
   7750    `_bfd_generic_link_add_one_symbol' handles the details of combining
   7751 common symbols, warning about multiple definitions, and so forth.  It
   7752 takes arguments which describe the symbol to add, notably symbol flags,
   7753 a section, and an offset.  The symbol flags include such things as
   7754 `BSF_WEAK' or `BSF_INDIRECT'.  The section is a section in the object
   7755 file, or something like `bfd_und_section_ptr' for an undefined symbol
   7756 or `bfd_com_section_ptr' for a common symbol.
   7757 
   7758    If the `_bfd_final_link' routine is also going to need to read the
   7759 symbol information, the `_bfd_link_add_symbols' routine should save it
   7760 somewhere attached to the object file BFD.  However, the information
   7761 should only be saved if the `keep_memory' field of the `info' argument
   7762 is TRUE, so that the `-no-keep-memory' linker switch is effective.
   7763 
   7764    The a.out function which adds symbols from an object file is
   7765 `aout_link_add_object_symbols', and most of the interesting work is in
   7766 `aout_link_add_symbols'.  The latter saves pointers to the hash tables
   7767 entries created by `_bfd_generic_link_add_one_symbol' indexed by symbol
   7768 number, so that the `_bfd_final_link' routine does not have to call the
   7769 hash table lookup routine to locate the entry.

   7773 
   7774 2.17.2.3 Adding symbols from an archive
   7775 .......................................
   7776 
   7777 When the `_bfd_link_add_symbols' routine is passed an archive, it must
   7778 look through the symbols defined by the archive and decide which
   7779 elements of the archive should be included in the link.  For each such
   7780 element it must call the `add_archive_element' linker callback, and it
   7781 must add the symbols from the object file to the linker hash table.
   7782 (The callback may in fact indicate that a replacement BFD should be
   7783 used, in which case the symbols from that BFD should be added to the
   7784 linker hash table instead.)
   7785 
   7786    In most cases the work of looking through the symbols in the archive
   7787 should be done by the `_bfd_generic_link_add_archive_symbols' function.
   7788 This function builds a hash table from the archive symbol table and
   7789 looks through the list of undefined symbols to see which elements
   7790 should be included.  `_bfd_generic_link_add_archive_symbols' is passed
   7791 a function to call to make the final decision about adding an archive
   7792 element to the link and to do the actual work of adding the symbols to
   7793 the linker hash table.
   7794 
   7795    The function passed to `_bfd_generic_link_add_archive_symbols' must
   7796 read the symbols of the archive element and decide whether the archive
   7797 element should be included in the link.  If the element is to be
   7798 included, the `add_archive_element' linker callback routine must be
   7799 called with the element as an argument, and the element's symbols must
   7800 be added to the linker hash table just as though the element had itself
   7801 been passed to the `_bfd_link_add_symbols' function.  The
   7802 `add_archive_element' callback has the option to indicate that it would
   7803 like to replace the element archive with a substitute BFD, in which
   7804 case it is the symbols of that substitute BFD that must be added to the
   7805 linker hash table instead.
   7806 
   7807    When the a.out `_bfd_link_add_symbols' function receives an archive,
   7808 it calls `_bfd_generic_link_add_archive_symbols' passing
   7809 `aout_link_check_archive_element' as the function argument.
   7810 `aout_link_check_archive_element' calls `aout_link_check_ar_symbols'.
   7811 If the latter decides to add the element (an element is only added if
   7812 it provides a real, non-common, definition for a previously undefined
   7813 or common symbol) it calls the `add_archive_element' callback and then
   7814 `aout_link_check_archive_element' calls `aout_link_add_symbols' to
   7815 actually add the symbols to the linker hash table - possibly those of a
   7816 substitute BFD, if the `add_archive_element' callback avails itself of
   7817 that option.
   7818 
   7819    The ECOFF back end is unusual in that it does not normally call
   7820 `_bfd_generic_link_add_archive_symbols', because ECOFF archives already
   7821 contain a hash table of symbols.  The ECOFF back end searches the
   7822 archive itself to avoid the overhead of creating a new hash table.

   7827 2.17.3 Performing the final link
   7828 --------------------------------
   7829 
   7830 When all the input files have been processed, the linker calls the
   7831 `_bfd_final_link' entry point of the output BFD.  This routine is
   7832 responsible for producing the final output file, which has several
   7833 aspects.  It must relocate the contents of the input sections and copy
   7834 the data into the output sections.  It must build an output symbol
   7835 table including any local symbols from the input files and the global
   7836 symbols from the hash table.  When producing relocatable output, it must
   7837 modify the input relocs and write them into the output file.  There may
   7838 also be object format dependent work to be done.
   7839 
   7840    The linker will also call the `write_object_contents' entry point
   7841 when the BFD is closed.  The two entry points must work together in
   7842 order to produce the correct output file.
   7843 
   7844    The details of how this works are inevitably dependent upon the
   7845 specific object file format.  The a.out `_bfd_final_link' routine is
   7846 `NAME(aout,final_link)'.

   7863    The `input_bfds' field of the `bfd_link_info' structure will point
   7864 to a list of all the input files included in the link.  These files are
   7865 linked through the `link_next' field of the `bfd' structure.
   7866 
   7867    Each section in the output file will have a list of `link_order'
   7868 structures attached to the `map_head.link_order' field (the
   7869 `link_order' structure is defined in `bfdlink.h').  These structures
   7870 describe how to create the contents of the output section in terms of
   7871 the contents of various input sections, fill constants, and,
   7872 eventually, other types of information.  They also describe relocs that
   7873 must be created by the BFD backend, but do not correspond to any input
   7874 file; this is used to support -Ur, which builds constructors while
   7875 generating a relocatable object file.

   7881 ........................................
   7882 
   7883 The `_bfd_final_link' function should look through the `link_order'
   7884 structures attached to each section of the output file.  Each
   7885 `link_order' structure should either be handled specially, or it should
   7886 be passed to the function `_bfd_default_link_order' which will do the
   7887 right thing (`_bfd_default_link_order' is defined in `linker.c').
   7888 
   7889    For efficiency, a `link_order' of type `bfd_indirect_link_order'
   7890 whose associated section belongs to a BFD of the same format as the
   7891 output BFD must be handled specially.  This type of `link_order'
   7892 describes part of an output section in terms of a section belonging to
   7893 one of the input files.  The `_bfd_final_link' function should read the
   7894 contents of the section and any associated relocs, apply the relocs to
   7895 the section contents, and write out the modified section contents.  If
   7896 performing a relocatable link, the relocs themselves must also be
   7897 modified and written out.
   7898 
   7899    The functions `_bfd_relocate_contents' and
   7900 `_bfd_final_link_relocate' provide some general support for performing
   7901 the actual relocations, notably overflow checking.  Their arguments
   7902 include information about the symbol the relocation is against and a
   7903 `reloc_howto_type' argument which describes the relocation to perform.
   7904 These functions are defined in `reloc.c'.
   7905 
   7906    The a.out function which handles reading, relocating, and writing
   7907 section contents is `aout_link_input_section'.  The actual relocation
   7908 is done in `aout_link_input_section_std' and
   7909 `aout_link_input_section_ext'.

   7914 2.17.3.3 Writing the symbol table
   7915 .................................
   7916 
   7917 The `_bfd_final_link' function must gather all the symbols in the input
   7918 files and write them out.  It must also write out all the symbols in
   7919 the global hash table.  This must be controlled by the `strip' and
   7920 `discard' fields of the `bfd_link_info' structure.
   7921 
   7922    The local symbols of the input files will not have been entered into
   7923 the linker hash table.  The `_bfd_final_link' routine must consider
   7924 each input file and include the symbols in the output file.  It may be
   7925 convenient to do this when looking through the `link_order' structures,
   7926 or it may be done by stepping through the `input_bfds' list.
   7927 
   7928    The `_bfd_final_link' routine must also traverse the global hash
   7929 table to gather all the externally visible symbols.  It is possible
   7930 that most of the externally visible symbols may be written out when
   7931 considering the symbols of each input file, but it is still necessary
   7932 to traverse the hash table since the linker script may have defined
   7933 some symbols that are not in any of the input files.
   7934 
   7935    The `strip' field of the `bfd_link_info' structure controls which
   7936 symbols are written out.  The possible values are listed in
   7937 `bfdlink.h'.  If the value is `strip_some', then the `keep_hash' field
   7938 of the `bfd_link_info' structure is a hash table of symbols to keep;
   7939 each symbol should be looked up in this hash table, and only symbols
   7940 which are present should be included in the output file.
   7941 
   7942    If the `strip' field of the `bfd_link_info' structure permits local
   7943 symbols to be written out, the `discard' field is used to further
   7944 controls which local symbols are included in the output file.  If the
   7945 value is `discard_l', then all local symbols which begin with a certain
   7946 prefix are discarded; this is controlled by the
   7947 `bfd_is_local_label_name' entry point.
   7948 
   7949    The a.out backend handles symbols by calling
   7950 `aout_link_write_symbols' on each input BFD and then traversing the
   7951 global hash table with the function `aout_link_write_other_symbol'.  It
   7952 builds a string table while writing out the symbols, which is written
   7953 to the output file at the end of `NAME(aout,final_link)'.

   8006 2.18 Hash Tables
   8007 ================
   8008 
   8009 BFD provides a simple set of hash table functions.  Routines are
   8010 provided to initialize a hash table, to free a hash table, to look up a
   8011 string in a hash table and optionally create an entry for it, and to
   8012 traverse a hash table.  There is currently no routine to delete an
   8013 string from a hash table.
   8014 
   8015    The basic hash table does not permit any data to be stored with a
   8016 string.  However, a hash table is designed to present a base class from
   8017 which other types of hash tables may be derived.  These derived types
   8018 may store additional information with the string.  Hash tables were
   8019 implemented in this way, rather than simply providing a data pointer in
   8020 a hash table entry, because they were designed for use by the linker
   8021 back ends.  The linker may create thousands of hash table entries, and
   8022 the overhead of allocating private data and storing and following
   8023 pointers becomes noticeable.
   8024 
   8025    The basic hash table code is in `hash.c'.

   8036 
   8037 2.18.1 Creating and freeing a hash table
   8038 ----------------------------------------
   8039 
   8040 To create a hash table, create an instance of a `struct bfd_hash_table'
   8041 (defined in `bfd.h') and call `bfd_hash_table_init' (if you know
   8042 approximately how many entries you will need, the function
   8043 `bfd_hash_table_init_n', which takes a SIZE argument, may be used).
   8044 `bfd_hash_table_init' returns `FALSE' if some sort of error occurs.
   8045 
   8046    The function `bfd_hash_table_init' take as an argument a function to
   8047 use to create new entries.  For a basic hash table, use the function
   8048 `bfd_hash_newfunc'.  *Note Deriving a New Hash Table Type::, for why
   8049 you would want to use a different value for this argument.
   8050 
   8051    `bfd_hash_table_init' will create an objalloc which will be used to
   8052 allocate new entries.  You may allocate memory on this objalloc using
   8053 `bfd_hash_allocate'.
   8054 
   8055    Use `bfd_hash_table_free' to free up all the memory that has been
   8056 allocated for a hash table.  This will not free up the `struct
   8057 bfd_hash_table' itself, which you must provide.
   8058 
   8059    Use `bfd_hash_set_default_size' to set the default size of hash
   8060 table to use.

   8064 
   8065 2.18.2 Looking up or entering a string
   8066 --------------------------------------
   8067 
   8068 The function `bfd_hash_lookup' is used both to look up a string in the
   8069 hash table and to create a new entry.
   8070 
   8071    If the CREATE argument is `FALSE', `bfd_hash_lookup' will look up a
   8072 string.  If the string is found, it will returns a pointer to a `struct
   8073 bfd_hash_entry'.  If the string is not found in the table
   8074 `bfd_hash_lookup' will return `NULL'.  You should not modify any of the
   8075 fields in the returns `struct bfd_hash_entry'.
   8076 
   8077    If the CREATE argument is `TRUE', the string will be entered into
   8078 the hash table if it is not already there.  Either way a pointer to a
   8079 `struct bfd_hash_entry' will be returned, either to the existing
   8080 structure or to a newly created one.  In this case, a `NULL' return
   8081 means that an error occurred.
   8082 
   8083    If the CREATE argument is `TRUE', and a new entry is created, the
   8084 COPY argument is used to decide whether to copy the string onto the
   8085 hash table objalloc or not.  If COPY is passed as `FALSE', you must be
   8086 careful not to deallocate or modify the string as long as the hash table
   8087 exists.

   8092 2.18.3 Traversing a hash table
   8093 ------------------------------
   8094 
   8095 The function `bfd_hash_traverse' may be used to traverse a hash table,
   8096 calling a function on each element.  The traversal is done in a random
   8097 order.
   8098 
   8099    `bfd_hash_traverse' takes as arguments a function and a generic
   8100 `void *' pointer.  The function is called with a hash table entry (a
   8101 `struct bfd_hash_entry *') and the generic pointer passed to
   8102 `bfd_hash_traverse'.  The function must return a `boolean' value, which
   8103 indicates whether to continue traversing the hash table.  If the
   8104 function returns `FALSE', `bfd_hash_traverse' will stop the traversal
   8105 and return immediately.

   8110 2.18.4 Deriving a new hash table type
   8111 -------------------------------------
   8112 
   8113 Many uses of hash tables want to store additional information which
   8114 each entry in the hash table.  Some also find it convenient to store
   8115 additional information with the hash table itself.  This may be done
   8116 using a derived hash table.
   8117 
   8118    Since C is not an object oriented language, creating a derived hash
   8119 table requires sticking together some boilerplate routines with a few
   8120 differences specific to the type of hash table you want to create.
   8121 
   8122    An example of a derived hash table is the linker hash table.  The
   8123 structures for this are defined in `bfdlink.h'.  The functions are in
   8124 `linker.c'.
   8125 
   8126    You may also derive a hash table from an already derived hash table.
   8127 For example, the a.out linker backend code uses a hash table derived
   8128 from the linker hash table.

   8139 2.18.4.1 Define the derived structures
   8140 ......................................
   8141 
   8142 You must define a structure for an entry in the hash table, and a
   8143 structure for the hash table itself.
   8144 
   8145    The first field in the structure for an entry in the hash table must
   8146 be of the type used for an entry in the hash table you are deriving
   8147 from.  If you are deriving from a basic hash table this is `struct
   8148 bfd_hash_entry', which is defined in `bfd.h'.  The first field in the
   8149 structure for the hash table itself must be of the type of the hash
   8150 table you are deriving from itself.  If you are deriving from a basic
   8151 hash table, this is `struct bfd_hash_table'.
   8152 
   8153    For example, the linker hash table defines `struct
   8154 bfd_link_hash_entry' (in `bfdlink.h').  The first field, `root', is of
   8155 type `struct bfd_hash_entry'.  Similarly, the first field in `struct
   8156 bfd_link_hash_table', `table', is of type `struct bfd_hash_table'.

   8161 2.18.4.2 Write the derived creation routine
   8162 ...........................................
   8163 
   8164 You must write a routine which will create and initialize an entry in
   8165 the hash table.  This routine is passed as the function argument to
   8166 `bfd_hash_table_init'.
   8167 
   8168    In order to permit other hash tables to be derived from the hash
   8169 table you are creating, this routine must be written in a standard way.
   8170 
   8171    The first argument to the creation routine is a pointer to a hash
   8172 table entry.  This may be `NULL', in which case the routine should
   8173 allocate the right amount of space.  Otherwise the space has already
   8174 been allocated by a hash table type derived from this one.
   8175 
   8176    After allocating space, the creation routine must call the creation
   8177 routine of the hash table type it is derived from, passing in a pointer
   8178 to the space it just allocated.  This will initialize any fields used
   8179 by the base hash table.
   8180 
   8181    Finally the creation routine must initialize any local fields for
   8182 the new hash table type.
   8183 
   8184    Here is a boilerplate example of a creation routine.  FUNCTION_NAME
   8185 is the name of the routine.  ENTRY_TYPE is the type of an entry in the
   8186 hash table you are creating.  BASE_NEWFUNC is the name of the creation
   8187 routine of the hash table type your hash table is derived from.

   8198        if (ret == NULL)
   8199          {
   8200            ret = bfd_hash_allocate (table, sizeof (* ret));
   8201            if (ret == NULL)
   8202              return NULL;
   8203          }

   8211        return (struct bfd_hash_entry *) ret;
   8212      }
   8213    *Description*
   8214 The creation routine for the linker hash table, which is in `linker.c',
   8215 looks just like this example.  FUNCTION_NAME is
   8216 `_bfd_link_hash_newfunc'.  ENTRY_TYPE is `struct bfd_link_hash_entry'.
   8217 BASE_NEWFUNC is `bfd_hash_newfunc', the creation routine for a basic
   8218 hash table.
   8219 
   8220    `_bfd_link_hash_newfunc' also initializes the local fields in a
   8221 linker hash table entry: `type', `written' and `next'.

   8226 2.18.4.3 Write other derived routines
   8227 .....................................
   8228 
   8229 You will want to write other routines for your new hash table, as well.
   8230 
   8231    You will want an initialization routine which calls the
   8232 initialization routine of the hash table you are deriving from and
   8233 initializes any other local fields.  For the linker hash table, this is
   8234 `_bfd_link_hash_table_init' in `linker.c'.
   8235 
   8236    You will want a lookup routine which calls the lookup routine of the
   8237 hash table you are deriving from and casts the result.  The linker hash
   8238 table uses `bfd_link_hash_lookup' in `linker.c' (this actually takes an
   8239 additional argument which it uses to decide how to return the looked up
   8240 value).
   8241 
   8242    You may want a traversal routine.  This should just call the
   8243 traversal routine of the hash table you are deriving from with
   8244 appropriate casts.  The linker hash table uses `bfd_link_hash_traverse'
   8245 in `linker.c'.
   8246 
   8247    These routines may simply be defined as macros.  For example, the
   8248 a.out backend linker hash table, which is derived from the linker hash
   8249 table, uses macros for the lookup and traversal routines.  These are
   8250 `aout_link_hash_lookup' and `aout_link_hash_traverse' in aoutx.h.

   8269 3.1 What to Put Where

   8271 
   8272 All of BFD lives in one directory.

   8277 3.2 a.out backends
   8278 ==================
   8279 
   8280 *Description*
   8281 BFD supports a number of different flavours of a.out format, though the
   8282 major differences are only the sizes of the structures on disk, and the
   8283 shape of the relocation information.
   8284 
   8285    The support is split into a basic support file `aoutx.h' and other
   8286 files which derive functions from the base. One derivation file is
   8287 `aoutf1.h' (for a.out flavour 1), and adds to the basic a.out functions
   8288 support for sun3, sun4, 386 and 29k a.out files, to create a target
   8289 jump vector for a specific target.
   8290 
   8291    This information is further split out into more specific files for
   8292 each machine, including `sunos.c' for sun3 and sun4, `newsos3.c' for
   8293 the Sony NEWS, and `demo64.c' for a demonstration of a 64 bit a.out
   8294 format.
   8295 
   8296    The base file `aoutx.h' defines general mechanisms for reading and
   8297 writing records to and from disk and various other methods which BFD
   8298 requires. It is included by `aout32.c' and `aout64.c' to form the names
   8299 `aout_32_swap_exec_header_in', `aout_64_swap_exec_header_in', etc.
   8300 
   8301    As an example, this is what goes on to make the back end for a sun4,
   8302 from `aout32.c':
   8303 
   8304             #define ARCH_SIZE 32
   8305             #include "aoutx.h"
   8306 
   8307    Which exports names:
   8308 
   8309             ...
   8310             aout_32_canonicalize_reloc
   8311             aout_32_find_nearest_line
   8312             aout_32_get_lineno
   8313             aout_32_get_reloc_upper_bound
   8314             ...
   8315 
   8316    from `sunos.c':
   8317 
   8318             #define TARGET_NAME "a.out-sunos-big"
   8319             #define VECNAME    sunos_big_vec
   8320             #include "aoutf1.h"
   8321 
   8322    requires all the names from `aout32.c', and produces the jump vector
   8323 
   8324             sunos_big_vec
   8325 
   8326    The file `host-aout.c' is a special case.  It is for a large set of
   8327 hosts that use "more or less standard" a.out files, and for which
   8328 cross-debugging is not interesting.  It uses the standard 32-bit a.out
   8329 support routines, but determines the file offsets and addresses of the
   8330 text, data, and BSS sections, the machine architecture and machine
   8331 type, and the entry point address, in a host-dependent manner.  Once
   8332 these values have been determined, generic code is used to handle the
   8333 object file.
   8334 
   8335    When porting it to run on a new system, you must supply:
   8336 
   8337              HOST_PAGE_SIZE
   8338              HOST_SEGMENT_SIZE
   8339              HOST_MACHINE_ARCH       (optional)
   8340              HOST_MACHINE_MACHINE    (optional)
   8341              HOST_TEXT_START_ADDR
   8342              HOST_STACK_END_ADDR
   8343 
   8344    in the file `../include/sys/h-XXX.h' (for your host).  These values,
   8345 plus the structures and macros defined in `a.out.h' on your host
   8346 system, will produce a BFD target that will access ordinary a.out files
   8347 on your host. To configure a new machine to use `host-aout.c', specify:
   8348 
   8349             TDEFAULTS = -DDEFAULT_VECTOR=host_aout_big_vec
   8350             TDEPFILES= host-aout.o trad-core.o
   8351 
   8352    in the `config/XXX.mt' file, and modify `configure.in' to use the
   8353 `XXX.mt' file (by setting "`bfd_target=XXX'") when your configuration
   8354 is selected.
   8355 
   8356 3.2.1 Relocations
   8357 -----------------
   8358 
   8359 *Description*
   8360 The file `aoutx.h' provides for both the _standard_ and _extended_
   8361 forms of a.out relocation records.
   8362 
   8363    The standard records contain only an address, a symbol index, and a
   8364 type field. The extended records (used on 29ks and sparcs) also have a
   8365 full integer for an addend.
   8366

   8368 ---------------------------
   8369 
   8370 *Description*
   8371 `aoutx.h' exports several routines for accessing the contents of an
   8372 a.out file, which are gathered and exported in turn by various format

   8464 3.3 coff backends
   8465 =================
   8466 
   8467 BFD supports a number of different flavours of coff format.  The major
   8468 differences between formats are the sizes and alignments of fields in
   8469 structures on disk, and the occasional extra field.
   8470 
   8471    Coff in all its varieties is implemented with a few common files and
   8472 a number of implementation specific files. For example, The 88k bcs
   8473 coff format is implemented in the file `coff-m88k.c'. This file
   8474 `#include's `coff/m88k.h' which defines the external structure of the
   8475 coff format for the 88k, and `coff/internal.h' which defines the
   8476 internal structure. `coff-m88k.c' also defines the relocations used by
   8477 the 88k format *Note Relocations::.
   8478 
   8479    The Intel i960 processor version of coff is implemented in
   8480 `coff-i960.c'. This file has the same structure as `coff-m88k.c',
   8481 except that it includes `coff/i960.h' rather than `coff-m88k.h'.
   8482 
   8483 3.3.1 Porting to a new version of coff
   8484 --------------------------------------
   8485 
   8486 The recommended method is to select from the existing implementations
   8487 the version of coff which is most like the one you want to use.  For
   8488 example, we'll say that i386 coff is the one you select, and that your
   8489 coff flavour is called foo.  Copy `i386coff.c' to `foocoff.c', copy
   8490 `../include/coff/i386.h' to `../include/coff/foo.h', and add the lines
   8491 to `targets.c' and `Makefile.in' so that your new back end is used.
   8492 Alter the shapes of the structures in `../include/coff/foo.h' so that
   8493 they match what you need. You will probably also have to add `#ifdef's
   8494 to the code in `coff/internal.h' and `coffcode.h' if your version of
   8495 coff is too wild.
   8496 
   8497    You can verify that your new BFD backend works quite simply by
   8498 building `objdump' from the `binutils' directory, and making sure that
   8499 its version of what's going on and your host system's idea (assuming it
   8500 has the pretty standard coff dump utility, usually called `att-dump' or
   8501 just `dump') are the same.  Then clean up your code, and send what
   8502 you've done to Cygnus. Then your stuff will be in the next release, and
   8503 you won't have to keep integrating it.
   8504 
   8505 3.3.2 How the coff backend works
   8506 --------------------------------
   8507 
   8508 3.3.2.1 File layout
   8509 ...................
   8510 
   8511 The Coff backend is split into generic routines that are applicable to
   8512 any Coff target and routines that are specific to a particular target.
   8513 The target-specific routines are further split into ones which are
   8514 basically the same for all Coff targets except that they use the
   8515 external symbol format or use different values for certain constants.
   8516 
   8517    The generic routines are in `coffgen.c'.  These routines work for
   8518 any Coff target.  They use some hooks into the target specific code;
   8519 the hooks are in a `bfd_coff_backend_data' structure, one of which
   8520 exists for each target.
   8521 
   8522    The essentially similar target-specific routines are in
   8523 `coffcode.h'.  This header file includes executable C code.  The
   8524 various Coff targets first include the appropriate Coff header file,
   8525 make any special defines that are needed, and then include `coffcode.h'.
   8526 
   8527    Some of the Coff targets then also have additional routines in the
   8528 target source file itself.
   8529 
   8530    For example, `coff-i960.c' includes `coff/internal.h' and
   8531 `coff/i960.h'.  It then defines a few constants, such as `I960', and
   8532 includes `coffcode.h'.  Since the i960 has complex relocation types,
   8533 `coff-i960.c' also includes some code to manipulate the i960 relocs.
   8534 This code is not in `coffcode.h' because it would not be used by any
   8535 other target.
   8536 
   8537 3.3.2.2 Coff long section names
   8538 ...............................
   8539 
   8540 In the standard Coff object format, section names are limited to the
   8541 eight bytes available in the `s_name' field of the `SCNHDR' section
   8542 header structure.  The format requires the field to be NUL-padded, but
   8543 not necessarily NUL-terminated, so the longest section names permitted
   8544 are a full eight characters.
   8545 
   8546    The Microsoft PE variants of the Coff object file format add an
   8547 extension to support the use of long section names.  This extension is
   8548 defined in section 4 of the Microsoft PE/COFF specification (rev 8.1).
   8549 If a section name is too long to fit into the section header's `s_name'
   8550 field, it is instead placed into the string table, and the `s_name'
   8551 field is filled with a slash ("/") followed by the ASCII decimal
   8552 representation of the offset of the full name relative to the string
   8553 table base.
   8554 
   8555    Note that this implies that the extension can only be used in object
   8556 files, as executables do not contain a string table.  The standard
   8557 specifies that long section names from objects emitted into executable
   8558 images are to be truncated.
   8559 
   8560    However, as a GNU extension, BFD can generate executable images that
   8561 contain a string table and long section names.  This would appear to be
   8562 technically valid, as the standard only says that Coff debugging
   8563 information is deprecated, not forbidden, and in practice it works,
   8564 although some tools that parse PE files expecting the MS standard
   8565 format may become confused; `PEview' is one known example.
   8566 
   8567    The functionality is supported in BFD by code implemented under the
   8568 control of the macro `COFF_LONG_SECTION_NAMES'.  If not defined, the
   8569 format does not support long section names in any way.  If defined, it
   8570 is used to initialise a flag, `_bfd_coff_long_section_names', and a
   8571 hook function pointer, `_bfd_coff_set_long_section_names', in the Coff
   8572 backend data structure.  The flag controls the generation of long
   8573 section names in output BFDs at runtime; if it is false, as it will be
   8574 by default when generating an executable image, long section names are
   8575 truncated; if true, the long section names extension is employed.  The
   8576 hook points to a function that allows the value of the flag to be
   8577 altered at runtime, on formats that support long section names at all;
   8578 on other formats it points to a stub that returns an error indication.
   8579 With input BFDs, the flag is set according to whether any long section
   8580 names are detected while reading the section headers.  For a completely
   8581 new BFD, the flag is set to the default for the target format.  This
   8582 information can be used by a client of the BFD library when deciding
   8583 what output format to generate, and means that a BFD that is opened for
   8584 read and subsequently converted to a writeable BFD and modified
   8585 in-place will retain whatever format it had on input.
   8586 
   8587    If `COFF_LONG_SECTION_NAMES' is simply defined (blank), or is
   8588 defined to the value "1", then long section names are enabled by
   8589 default; if it is defined to the value zero, they are disabled by
   8590 default (but still accepted in input BFDs).  The header `coffcode.h'
   8591 defines a macro, `COFF_DEFAULT_LONG_SECTION_NAMES', which is used in
   8592 the backends to initialise the backend data structure fields
   8593 appropriately; see the comments for further detail.
   8594 
   8595 3.3.2.3 Bit twiddling
   8596 .....................
   8597 
   8598 Each flavour of coff supported in BFD has its own header file
   8599 describing the external layout of the structures. There is also an
   8600 internal description of the coff layout, in `coff/internal.h'. A major
   8601 function of the coff backend is swapping the bytes and twiddling the
   8602 bits to translate the external form of the structures into the normal
   8603 internal form. This is all performed in the `bfd_swap'_thing_direction
   8604 routines. Some elements are different sizes between different versions
   8605 of coff; it is the duty of the coff version specific include file to
   8606 override the definitions of various packing routines in `coffcode.h'.
   8607 E.g., the size of line number entry in coff is sometimes 16 bits, and
   8608 sometimes 32 bits. `#define'ing `PUT_LNSZ_LNNO' and `GET_LNSZ_LNNO'
   8609 will select the correct one. No doubt, some day someone will find a
   8610 version of coff which has a varying field size not catered to at the
   8611 moment. To port BFD, that person will have to add more `#defines'.
   8612 Three of the bit twiddling routines are exported to `gdb';
   8613 `coff_swap_aux_in', `coff_swap_sym_in' and `coff_swap_lineno_in'. `GDB'
   8614 reads the symbol table on its own, but uses BFD to fix things up.  More
   8615 of the bit twiddlers are exported for `gas'; `coff_swap_aux_out',
   8616 `coff_swap_sym_out', `coff_swap_lineno_out', `coff_swap_reloc_out',
   8617 `coff_swap_filehdr_out', `coff_swap_aouthdr_out',
   8618 `coff_swap_scnhdr_out'. `Gas' currently keeps track of all the symbol
   8619 table and reloc drudgery itself, thereby saving the internal BFD
   8620 overhead, but uses BFD to swap things on the way out, making cross
   8621 ports much safer.  Doing so also allows BFD (and thus the linker) to
   8622 use the same header files as `gas', which makes one avenue to disaster
   8623 disappear.
   8624 
   8625 3.3.2.4 Symbol reading
   8626 ......................
   8627 
   8628 The simple canonical form for symbols used by BFD is not rich enough to
   8629 keep all the information available in a coff symbol table. The back end
   8630 gets around this problem by keeping the original symbol table around,
   8631 "behind the scenes".
   8632 
   8633    When a symbol table is requested (through a call to
   8634 `bfd_canonicalize_symtab'), a request gets through to
   8635 `coff_get_normalized_symtab'. This reads the symbol table from the coff
   8636 file and swaps all the structures inside into the internal form. It
   8637 also fixes up all the pointers in the table (represented in the file by
   8638 offsets from the first symbol in the table) into physical pointers to
   8639 elements in the new internal table. This involves some work since the
   8640 meanings of fields change depending upon context: a field that is a
   8641 pointer to another structure in the symbol table at one moment may be
   8642 the size in bytes of a structure at the next.  Another pass is made
   8643 over the table. All symbols which mark file names (`C_FILE' symbols)
   8644 are modified so that the internal string points to the value in the
   8645 auxent (the real filename) rather than the normal text associated with
   8646 the symbol (`".file"').
   8647 
   8648    At this time the symbol names are moved around. Coff stores all
   8649 symbols less than nine characters long physically within the symbol
   8650 table; longer strings are kept at the end of the file in the string
   8651 table. This pass moves all strings into memory and replaces them with
   8652 pointers to the strings.
   8653 
   8654    The symbol table is massaged once again, this time to create the
   8655 canonical table used by the BFD application. Each symbol is inspected
   8656 in turn, and a decision made (using the `sclass' field) about the
   8657 various flags to set in the `asymbol'.  *Note Symbols::. The generated
   8658 canonical table shares strings with the hidden internal symbol table.
   8659 
   8660    Any linenumbers are read from the coff file too, and attached to the
   8661 symbols which own the functions the linenumbers belong to.
   8662 
   8663 3.3.2.5 Symbol writing
   8664 ......................
   8665 
   8666 Writing a symbol to a coff file which didn't come from a coff file will
   8667 lose any debugging information. The `asymbol' structure remembers the
   8668 BFD from which the symbol was taken, and on output the back end makes
   8669 sure that the same destination target as source target is present.
   8670 
   8671    When the symbols have come from a coff file then all the debugging
   8672 information is preserved.
   8673 
   8674    Symbol tables are provided for writing to the back end in a vector
   8675 of pointers to pointers. This allows applications like the linker to
   8676 accumulate and output large symbol tables without having to do too much
   8677 byte copying.
   8678 
   8679    This function runs through the provided symbol table and patches
   8680 each symbol marked as a file place holder (`C_FILE') to point to the
   8681 next file place holder in the list. It also marks each `offset' field
   8682 in the list with the offset from the first symbol of the current symbol.
   8683 
   8684    Another function of this procedure is to turn the canonical value
   8685 form of BFD into the form used by coff. Internally, BFD expects symbol
   8686 values to be offsets from a section base; so a symbol physically at
   8687 0x120, but in a section starting at 0x100, would have the value 0x20.
   8688 Coff expects symbols to contain their final value, so symbols have
   8689 their values changed at this point to reflect their sum with their
   8690 owning section.  This transformation uses the `output_section' field of
   8691 the `asymbol''s `asection' *Note Sections::.
   8692 
   8693    * `coff_mangle_symbols'
   8694    This routine runs though the provided symbol table and uses the
   8695 offsets generated by the previous pass and the pointers generated when
   8696 the symbol table was read in to create the structured hierarchy
   8697 required by coff. It changes each pointer to a symbol into the index
   8698 into the symbol table of the asymbol.
   8699 
   8700    * `coff_write_symbols'
   8701    This routine runs through the symbol table and patches up the
   8702 symbols from their internal form into the coff way, calls the bit
   8703 twiddlers, and writes out the table to the file.

   9064 3.3.2.8 Writing relocations
   9065 ...........................
   9066 
   9067 To write relocations, the back end steps though the canonical
   9068 relocation table and create an `internal_reloc'. The symbol index to
   9069 use is removed from the `offset' field in the symbol table supplied.
   9070 The address comes directly from the sum of the section base address and
   9071 the relocation offset; the type is dug directly from the howto field.
   9072 Then the `internal_reloc' is swapped into the shape of an
   9073 `external_reloc' and written out to disk.
   9074 
   9075 3.3.2.9 Reading linenumbers
   9076 ...........................
   9077 
   9078 Creating the linenumber table is done by reading in the entire coff
   9079 linenumber table, and creating another table for internal use.
   9080 
   9081    A coff linenumber table is structured so that each function is
   9082 marked as having a line number of 0. Each line within the function is
   9083 an offset from the first line in the function. The base of the line
   9084 number information for the table is stored in the symbol associated
   9085 with the function.
   9086 
   9087    Note: The PE format uses line number 0 for a flag indicating a new
   9088 source file.
   9089 
   9090    The information is copied from the external to the internal table,
   9091 and each symbol which marks a function is marked by pointing its...
   9092 
   9093    How does this work ?
   9094 
   9095 3.3.2.10 Reading relocations
   9096 ............................
   9097 
   9098 Coff relocations are easily transformed into the internal BFD form
   9099 (`arelent').
   9100 
   9101    Reading a coff relocation table is done in the following stages:
   9102 
   9103    * Read the entire coff relocation table into memory.
   9104 
   9105    * Process each relocation in turn; first swap it from the external
   9106      to the internal form.
   9107 
   9108    * Turn the symbol referenced in the relocation's symbol index into a
   9109      pointer into the canonical symbol table.  This table is the same
   9110      as the one returned by a call to `bfd_canonicalize_symtab'. The
   9111      back end will call that routine and save the result if a
   9112      canonicalization hasn't been done.
   9113 
   9114    * The reloc index is turned into a pointer to a howto structure, in
   9115      a back end specific way. For instance, the 386 and 960 use the
   9116      `r_type' to directly produce an index into a howto table vector;
   9117      the 88k subtracts a number from the `r_type' field and creates an
   9118      addend field.

   9123 3.4 ELF backends
   9124 ================
   9125 
   9126 BFD support for ELF formats is being worked on.  Currently, the best
   9127 supported back ends are for sparc and i386 (running svr4 or Solaris 2).
   9128 
   9129    Documentation of the internals of the support code still needs to be
   9130 written.  The code is changing quickly enough that we haven't bothered
   9131 yet.

   9135 
   9136 3.5 mmo backend
   9137 ===============
   9138 
   9139 The mmo object format is used exclusively together with Professor
   9140 Donald E. Knuth's educational 64-bit processor MMIX.  The simulator
   9141 `mmix' which is available at
   9142 `http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz'
   9143 understands this format.  That package also includes a combined
   9144 assembler and linker called `mmixal'.  The mmo format has no advantages
   9145 feature-wise compared to e.g. ELF.  It is a simple non-relocatable
   9146 object format with no support for archives or debugging information,
   9147 except for symbol value information and line numbers (which is not yet
   9148 implemented in BFD).  See
   9149 `http://www-cs-faculty.stanford.edu/~knuth/mmix.html' for more
   9150 information about MMIX.  The ELF format is used for intermediate object
   9151 files in the BFD implementation.

   9162 3.5.1 File layout
   9163 -----------------
   9164 
   9165 The mmo file contents is not partitioned into named sections as with
   9166 e.g. ELF.  Memory areas is formed by specifying the location of the
   9167 data that follows.  Only the memory area `0x0000...00' to `0x01ff...ff'
   9168 is executable, so it is used for code (and constants) and the area
   9169 `0x2000...00' to `0x20ff...ff' is used for writable data.  *Note mmo
   9170 section mapping::.
   9171 
   9172    There is provision for specifying "special data" of 65536 different
   9173 types.  We use type 80 (decimal), arbitrarily chosen the same as the
   9174 ELF `e_machine' number for MMIX, filling it with section information
   9175 normally found in ELF objects. *Note mmo section mapping::.
   9176 
   9177    Contents is entered as 32-bit words, xor:ed over previous contents,
   9178 always zero-initialized.  A word that starts with the byte `0x98' forms
   9179 a command called a `lopcode', where the next byte distinguished between
   9180 the thirteen lopcodes.  The two remaining bytes, called the `Y' and `Z'
   9181 fields, or the `YZ' field (a 16-bit big-endian number), are used for
   9182 various purposes different for each lopcode.  As documented in
   9183 `http://www-cs-faculty.stanford.edu/~knuth/mmixal-intro.ps.gz', the
   9184 lopcodes are:
   9185 
   9186 `lop_quote'
   9187      0x98000001.  The next word is contents, regardless of whether it
   9188      starts with 0x98 or not.
   9189 
   9190 `lop_loc'
   9191      0x9801YYZZ, where `Z' is 1 or 2.  This is a location directive,
   9192      setting the location for the next data to the next 32-bit word
   9193      (for Z = 1) or 64-bit word (for Z = 2), plus Y * 2^56.  Normally
   9194      `Y' is 0 for the text segment and 2 for the data segment.
   9195 
   9196 `lop_skip'
   9197      0x9802YYZZ.  Increase the current location by `YZ' bytes.
   9198 
   9199 `lop_fixo'
   9200      0x9803YYZZ, where `Z' is 1 or 2.  Store the current location as 64
   9201      bits into the location pointed to by the next 32-bit (Z = 1) or
   9202      64-bit (Z = 2) word, plus Y * 2^56.
   9203 
   9204 `lop_fixr'
   9205      0x9804YYZZ.  `YZ' is stored into the current location plus 2 - 4 *
   9206      YZ.
   9207 
   9208 `lop_fixrx'
   9209      0x980500ZZ.  `Z' is 16 or 24.  A value `L' derived from the
   9210      following 32-bit word are used in a manner similar to `YZ' in
   9211      lop_fixr: it is xor:ed into the current location minus 4 * L.  The
   9212      first byte of the word is 0 or 1.  If it is 1, then L = (LOWEST 24
   9213      BITS OF WORD) - 2^Z, if 0, then L = (LOWEST 24 BITS OF WORD).
   9214 
   9215 `lop_file'
   9216      0x9806YYZZ.  `Y' is the file number, `Z' is count of 32-bit words.
   9217      Set the file number to `Y' and the line counter to 0.  The next Z
   9218      * 4 bytes contain the file name, padded with zeros if the count is
   9219      not a multiple of four.  The same `Y' may occur multiple times,
   9220      but `Z' must be 0 for all but the first occurrence.
   9221 
   9222 `lop_line'
   9223      0x9807YYZZ.  `YZ' is the line number.  Together with lop_file, it
   9224      forms the source location for the next 32-bit word.  Note that for
   9225      each non-lopcode 32-bit word, line numbers are assumed incremented
   9226      by one.
   9227 
   9228 `lop_spec'
   9229      0x9808YYZZ.  `YZ' is the type number.  Data until the next lopcode
   9230      other than lop_quote forms special data of type `YZ'.  *Note mmo
   9231      section mapping::.
   9232 
   9233      Other types than 80, (or type 80 with a content that does not
   9234      parse) is stored in sections named `.MMIX.spec_data.N' where N is
   9235      the `YZ'-type.  The flags for such a sections say not to allocate
   9236      or load the data.  The vma is 0.  Contents of multiple occurrences
   9237      of special data N is concatenated to the data of the previous
   9238      lop_spec Ns.  The location in data or code at which the lop_spec
   9239      occurred is lost.
   9240 
   9241 `lop_pre'
   9242      0x980901ZZ.  The first lopcode in a file.  The `Z' field forms the
   9243      length of header information in 32-bit words, where the first word
   9244      tells the time in seconds since `00:00:00 GMT Jan 1 1970'.
   9245 
   9246 `lop_post'
   9247      0x980a00ZZ.  Z > 32.  This lopcode follows after all
   9248      content-generating lopcodes in a program.  The `Z' field denotes
   9249      the value of `rG' at the beginning of the program.  The following
   9250      256 - Z big-endian 64-bit words are loaded into global registers
   9251      `$G' ... `$255'.
   9252 
   9253 `lop_stab'
   9254      0x980b0000.  The next-to-last lopcode in a program.  Must follow
   9255      immediately after the lop_post lopcode and its data.  After this
   9256      lopcode follows all symbols in a compressed format (*note
   9257      Symbol-table::).
   9258 
   9259 `lop_end'
   9260      0x980cYYZZ.  The last lopcode in a program.  It must follow the
   9261      lop_stab lopcode and its data.  The `YZ' field contains the number
   9262      of 32-bit words of symbol table information after the preceding
   9263      lop_stab lopcode.
   9264 
   9265    Note that the lopcode "fixups"; `lop_fixr', `lop_fixrx' and
   9266 `lop_fixo' are not generated by BFD, but are handled.  They are
   9267 generated by `mmixal'.

   9304 `http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz'):
   9305 "Symbols are stored and retrieved by means of a `ternary search trie',
   9306 following ideas of Bentley and Sedgewick. (See ACM-SIAM Symp. on
   9307 Discrete Algorithms `8' (1997), 360-369; R.Sedgewick, `Algorithms in C'
   9308 (Reading, Mass.  Addison-Wesley, 1998), `15.4'.)  Each trie node stores
   9309 a character, and there are branches to subtries for the cases where a
   9310 given character is less than, equal to, or greater than the character
   9311 in the trie.  There also is a pointer to a symbol table entry if a
   9312 symbol ends at the current node."
   9313 
   9314    So it's a tree encoded as a stream of bytes.  The stream of bytes
   9315 acts on a single virtual global symbol, adding and removing characters
   9316 and signalling complete symbol points.  Here, we read the stream and
   9317 create symbols at the completion points.
   9318 
   9319    First, there's a control byte `m'.  If any of the listed bits in `m'
   9320 is nonzero, we execute what stands at the right, in the listed order:
   9321 
   9322       (MMO3_LEFT)
   9323       0x40 - Traverse left trie.
   9324              (Read a new command byte and recurse.)
   9325 
   9326       (MMO3_SYMBITS)
   9327       0x2f - Read the next byte as a character and store it in the
   9328              current character position; increment character position.
   9329              Test the bits of `m':
   9330 
   9331              (MMO3_WCHAR)
   9332              0x80 - The character is 16-bit (so read another byte,
   9333                     merge into current character.
   9334 
   9335              (MMO3_TYPEBITS)
   9336              0xf  - We have a complete symbol; parse the type, value
   9337                     and serial number and do what should be done
   9338                     with a symbol.  The type and length information
   9339                     is in j = (m & 0xf).
   9340 
   9341                     (MMO3_REGQUAL_BITS)
   9342                     j == 0xf: A register variable.  The following
   9343                               byte tells which register.
   9344                     j <= 8:   An absolute symbol.  Read j bytes as the
   9345                               big-endian number the symbol equals.
   9346                               A j = 2 with two zero bytes denotes an
   9347                               unknown symbol.
   9348                     j > 8:    As with j <= 8, but add (0x20 << 56)
   9349                               to the value in the following j - 8
   9350                               bytes.
   9351 
   9352                     Then comes the serial number, as a variant of
   9353                     uleb128, but better named ubeb128:
   9354                     Read bytes and shift the previous value left 7
   9355                     (multiply by 128).  Add in the new byte, repeat
   9356                     until a byte has bit 7 set.  The serial number
   9357                     is the computed value minus 128.
   9358 
   9359              (MMO3_MIDDLE)
   9360              0x20 - Traverse middle trie.  (Read a new command byte
   9361                     and recurse.)  Decrement character position.
   9362 
   9363       (MMO3_RIGHT)
   9364       0x10 - Traverse right trie.  (Read a new command byte and
   9365              recurse.)
   9366 
   9367    Let's look again at the `lop_stab' for the trivial file (*note File
   9368 layout::).
   9369 
   9370       0x980b0000 - lop_stab for ":Main" = 0, serial 1.
   9371       0x203a4040
   9372       0x10404020
   9373       0x4d206120
   9374       0x69016e00
   9375       0x81000000
   9376 
   9377    This forms the trivial trie (note that the path between ":" and "M"
   9378 is redundant):
   9379 
   9380       203a     ":"
   9381       40       /
   9382       40      /
   9383       10      \
   9384       40      /
   9385       40     /
   9386       204d  "M"
   9387       2061  "a"
   9388       2069  "i"
   9389       016e  "n" is the last character in a full symbol, and
   9390             with a value represented in one byte.
   9391       00    The value is 0.
   9392       81    The serial number is 1.

   9396 
   9397 3.5.3 mmo section mapping
   9398 -------------------------
   9399 
   9400 The implementation in BFD uses special data type 80 (decimal) to
   9401 encapsulate and describe named sections, containing e.g. debug
   9402 information.  If needed, any datum in the encapsulation will be quoted
   9403 using lop_quote.  First comes a 32-bit word holding the number of
   9404 32-bit words containing the zero-terminated zero-padded segment name.
   9405 After the name there's a 32-bit word holding flags describing the
   9406 section type.  Then comes a 64-bit big-endian word with the section
   9407 length (in bytes), then another with the section start address.
   9408 Depending on the type of section, the contents might follow,
   9409 zero-padded to 32-bit boundary.  For a loadable section (such as data
   9410 or code), the contents might follow at some later point, not
   9411 necessarily immediately, as a lop_loc with the same start address as in
   9412 the section description, followed by the contents.  This in effect
   9413 forms a descriptor that must be emitted before the actual contents.
   9414 Sections described this way must not overlap.
   9415 
   9416    For areas that don't have such descriptors, synthetic sections are
   9417 formed by BFD.  Consecutive contents in the two memory areas
   9418 `0x0000...00' to `0x01ff...ff' and `0x2000...00' to `0x20ff...ff' are
   9419 entered in sections named `.text' and `.data' respectively.  If an area
   9420 is not otherwise described, but would together with a neighboring lower
   9421 area be less than `0x40000000' bytes long, it is joined with the lower
   9422 area and the gap is zero-filled.  For other cases, a new section is
   9423 formed, named `.MMIX.sec.N'.  Here, N is a number, a running count
   9424 through the mmo file, starting at 0.
   9425 
   9426    A loadable section specified as:
   9427 
   9428       .section secname,"ax"
   9429       TETRA 1,2,3,4,-1,-2009
   9430       BYTE 80
   9431 
   9432    and linked to address `0x4', is represented by the sequence:
   9433 
   9434       0x98080050 - lop_spec 80
   9435       0x00000002 - two 32-bit words for the section name
   9436       0x7365636e - "secn"
   9437       0x616d6500 - "ame\0"
   9438       0x00000033 - flags CODE, READONLY, LOAD, ALLOC
   9439       0x00000000 - high 32 bits of section length
   9440       0x0000001c - section length is 28 bytes; 6 * 4 + 1 + alignment to 32 bits
   9441       0x00000000 - high 32 bits of section address
   9442       0x00000004 - section address is 4
   9443       0x98010002 - 64 bits with address of following data
   9444       0x00000000 - high 32 bits of address
   9445       0x00000004 - low 32 bits: data starts at address 4
   9446       0x00000001 - 1
   9447       0x00000002 - 2
   9448       0x00000003 - 3
   9449       0x00000004 - 4
   9450       0xffffffff - -1
   9451       0xfffff827 - -2009
   9452       0x50000000 - 80 as a byte, padded with zeros.
   9453 
   9454    Note that the lop_spec wrapping does not include the section
   9455 contents.  Compare this to a non-loaded section specified as:
   9456 
   9457       .section thirdsec
   9458       TETRA 200001,100002
   9459       BYTE 38,40
   9460 
   9461    This, when linked to address `0x200000000000001c', is represented by:
   9462 
   9463       0x98080050 - lop_spec 80
   9464       0x00000002 - two 32-bit words for the section name
   9465       0x7365636e - "thir"
   9466       0x616d6500 - "dsec"
   9467       0x00000010 - flag READONLY
   9468       0x00000000 - high 32 bits of section length
   9469       0x0000000c - section length is 12 bytes; 2 * 4 + 2 + alignment to 32 bits
   9470       0x20000000 - high 32 bits of address
   9471       0x0000001c - low 32 bits of address 0x200000000000001c
   9472       0x00030d41 - 200001
   9473       0x000186a2 - 100002
   9474       0x26280000 - 38, 40 as bytes, padded with zeros
   9475 
   9476    For the latter example, the section contents must not be loaded in
   9477 memory, and is therefore specified as part of the special data.  The
   9478 address is usually unimportant but might provide information for e.g.
   9479 the DWARF 2 debugging format.

   9492   0. PREAMBLE
   9493 
   9494      The purpose of this License is to make a manual, textbook, or other
   9495      functional and useful document "free" in the sense of freedom: to
   9496      assure everyone the effective freedom to copy and redistribute it,
   9497      with or without modifying it, either commercially or
   9498      noncommercially.  Secondarily, this License preserves for the
   9499      author and publisher a way to get credit for their work, while not
   9500      being considered responsible for modifications made by others.
   9501 
   9502      This License is a kind of "copyleft", which means that derivative
   9503      works of the document must themselves be free in the same sense.
   9504      It complements the GNU General Public License, which is a copyleft
   9505      license designed for free software.
   9506 
   9507      We have designed this License in order to use it for manuals for
   9508      free software, because free software needs free documentation: a
   9509      free program should come with manuals providing the same freedoms
   9510      that the software does.  But this License is not limited to
   9511      software manuals; it can be used for any textual work, regardless
   9512      of subject matter or whether it is published as a printed book.
   9513      We recommend this License principally for works whose purpose is
   9514      instruction or reference.
   9515 
   9516   1. APPLICABILITY AND DEFINITIONS
   9517 
   9518      This License applies to any manual or other work, in any medium,
   9519      that contains a notice placed by the copyright holder saying it
   9520      can be distributed under the terms of this License.  Such a notice
   9521      grants a world-wide, royalty-free license, unlimited in duration,
   9522      to use that work under the conditions stated herein.  The
   9523      "Document", below, refers to any such manual or work.  Any member
   9524      of the public is a licensee, and is addressed as "you".  You
   9525      accept the license if you copy, modify or distribute the work in a
   9526      way requiring permission under copyright law.
   9527 
   9528      A "Modified Version" of the Document means any work containing the
   9529      Document or a portion of it, either copied verbatim, or with
   9530      modifications and/or translated into another language.
   9531 
   9532      A "Secondary Section" is a named appendix or a front-matter section
   9533      of the Document that deals exclusively with the relationship of the
   9534      publishers or authors of the Document to the Document's overall
   9535      subject (or to related matters) and contains nothing that could
   9536      fall directly within that overall subject.  (Thus, if the Document
   9537      is in part a textbook of mathematics, a Secondary Section may not
   9538      explain any mathematics.)  The relationship could be a matter of
   9539      historical connection with the subject or with related matters, or
   9540      of legal, commercial, philosophical, ethical or political position
   9541      regarding them.
   9542 
   9543      The "Invariant Sections" are certain Secondary Sections whose
   9544      titles are designated, as being those of Invariant Sections, in
   9545      the notice that says that the Document is released under this
   9546      License.  If a section does not fit the above definition of
   9547      Secondary then it is not allowed to be designated as Invariant.
   9548      The Document may contain zero Invariant Sections.  If the Document
   9549      does not identify any Invariant Sections then there are none.
   9550 
   9551      The "Cover Texts" are certain short passages of text that are
   9552      listed, as Front-Cover Texts or Back-Cover Texts, in the notice
   9553      that says that the Document is released under this License.  A
   9554      Front-Cover Text may be at most 5 words, and a Back-Cover Text may
   9555      be at most 25 words.
   9556 
   9557      A "Transparent" copy of the Document means a machine-readable copy,
   9558      represented in a format whose specification is available to the
   9559      general public, that is suitable for revising the document
   9560      straightforwardly with generic text editors or (for images
   9561      composed of pixels) generic paint programs or (for drawings) some
   9562      widely available drawing editor, and that is suitable for input to
   9563      text formatters or for automatic translation to a variety of
   9564      formats suitable for input to text formatters.  A copy made in an
   9565      otherwise Transparent file format whose markup, or absence of
   9566      markup, has been arranged to thwart or discourage subsequent
   9567      modification by readers is not Transparent.  An image format is
   9568      not Transparent if used for any substantial amount of text.  A
   9569      copy that is not "Transparent" is called "Opaque".
   9570 
   9571      Examples of suitable formats for Transparent copies include plain
   9572      ASCII without markup, Texinfo input format, LaTeX input format,
   9573      SGML or XML using a publicly available DTD, and
   9574      standard-conforming simple HTML, PostScript or PDF designed for
   9575      human modification.  Examples of transparent image formats include
   9576      PNG, XCF and JPG.  Opaque formats include proprietary formats that
   9577      can be read and edited only by proprietary word processors, SGML or
   9578      XML for which the DTD and/or processing tools are not generally
   9579      available, and the machine-generated HTML, PostScript or PDF
   9580      produced by some word processors for output purposes only.
   9581 
   9582      The "Title Page" means, for a printed book, the title page itself,
   9583      plus such following pages as are needed to hold, legibly, the
   9584      material this License requires to appear in the title page.  For
   9585      works in formats which do not have any title page as such, "Title
   9586      Page" means the text near the most prominent appearance of the
   9587      work's title, preceding the beginning of the body of the text.
   9588 
   9589      The "publisher" means any person or entity that distributes copies
   9590      of the Document to the public.
   9591 
   9592      A section "Entitled XYZ" means a named subunit of the Document
   9593      whose title either is precisely XYZ or contains XYZ in parentheses
   9594      following text that translates XYZ in another language.  (Here XYZ
   9595      stands for a specific section name mentioned below, such as
   9596      "Acknowledgements", "Dedications", "Endorsements", or "History".)
   9597      To "Preserve the Title" of such a section when you modify the
   9598      Document means that it remains a section "Entitled XYZ" according
   9599      to this definition.
   9600 
   9601      The Document may include Warranty Disclaimers next to the notice
   9602      which states that this License applies to the Document.  These
   9603      Warranty Disclaimers are considered to be included by reference in
   9604      this License, but only as regards disclaiming warranties: any other
   9605      implication that these Warranty Disclaimers may have is void and
   9606      has no effect on the meaning of this License.
   9607 
   9608   2. VERBATIM COPYING
   9609 
   9610      You may copy and distribute the Document in any medium, either
   9611      commercially or noncommercially, provided that this License, the
   9612      copyright notices, and the license notice saying this License
   9613      applies to the Document are reproduced in all copies, and that you
   9614      add no other conditions whatsoever to those of this License.  You
   9615      may not use technical measures to obstruct or control the reading
   9616      or further copying of the copies you make or distribute.  However,
   9617      you may accept compensation in exchange for copies.  If you
   9618      distribute a large enough number of copies you must also follow
   9619      the conditions in section 3.
   9620 
   9621      You may also lend copies, under the same conditions stated above,
   9622      and you may publicly display copies.
   9623 
   9624   3. COPYING IN QUANTITY
   9625 
   9626      If you publish printed copies (or copies in media that commonly
   9627      have printed covers) of the Document, numbering more than 100, and
   9628      the Document's license notice requires Cover Texts, you must
   9629      enclose the copies in covers that carry, clearly and legibly, all
   9630      these Cover Texts: Front-Cover Texts on the front cover, and
   9631      Back-Cover Texts on the back cover.  Both covers must also clearly
   9632      and legibly identify you as the publisher of these copies.  The
   9633      front cover must present the full title with all words of the
   9634      title equally prominent and visible.  You may add other material
   9635      on the covers in addition.  Copying with changes limited to the
   9636      covers, as long as they preserve the title of the Document and
   9637      satisfy these conditions, can be treated as verbatim copying in
   9638      other respects.
   9639 
   9640      If the required texts for either cover are too voluminous to fit
   9641      legibly, you should put the first ones listed (as many as fit
   9642      reasonably) on the actual cover, and continue the rest onto
   9643      adjacent pages.
   9644 
   9645      If you publish or distribute Opaque copies of the Document
   9646      numbering more than 100, you must either include a
   9647      machine-readable Transparent copy along with each Opaque copy, or
   9648      state in or with each Opaque copy a computer-network location from
   9649      which the general network-using public has access to download
   9650      using public-standard network protocols a complete Transparent
   9651      copy of the Document, free of added material.  If you use the
   9652      latter option, you must take reasonably prudent steps, when you
   9653      begin distribution of Opaque copies in quantity, to ensure that
   9654      this Transparent copy will remain thus accessible at the stated
   9655      location until at least one year after the last time you
   9656      distribute an Opaque copy (directly or through your agents or
   9657      retailers) of that edition to the public.
   9658 
   9659      It is requested, but not required, that you contact the authors of
   9660      the Document well before redistributing any large number of
   9661      copies, to give them a chance to provide you with an updated
   9662      version of the Document.
   9663 
   9664   4. MODIFICATIONS
   9665 
   9666      You may copy and distribute a Modified Version of the Document
   9667      under the conditions of sections 2 and 3 above, provided that you
   9668      release the Modified Version under precisely this License, with
   9669      the Modified Version filling the role of the Document, thus
   9670      licensing distribution and modification of the Modified Version to
   9671      whoever possesses a copy of it.  In addition, you must do these
   9672      things in the Modified Version:
   9673 
   9674        A. Use in the Title Page (and on the covers, if any) a title
   9675           distinct from that of the Document, and from those of
   9676           previous versions (which should, if there were any, be listed
   9677           in the History section of the Document).  You may use the
   9678           same title as a previous version if the original publisher of
   9679           that version gives permission.
   9680 
   9681        B. List on the Title Page, as authors, one or more persons or
   9682           entities responsible for authorship of the modifications in
   9683           the Modified Version, together with at least five of the
   9684           principal authors of the Document (all of its principal
   9685           authors, if it has fewer than five), unless they release you
   9686           from this requirement.
   9687 
   9688        C. State on the Title page the name of the publisher of the
   9689           Modified Version, as the publisher.
   9690 
   9691        D. Preserve all the copyright notices of the Document.
   9692 
   9693        E. Add an appropriate copyright notice for your modifications
   9694           adjacent to the other copyright notices.
   9695 
   9696        F. Include, immediately after the copyright notices, a license
   9697           notice giving the public permission to use the Modified
   9698           Version under the terms of this License, in the form shown in
   9699           the Addendum below.
   9700 
   9701        G. Preserve in that license notice the full lists of Invariant
   9702           Sections and required Cover Texts given in the Document's
   9703           license notice.
   9704 
   9705        H. Include an unaltered copy of this License.
   9706 
   9707        I. Preserve the section Entitled "History", Preserve its Title,
   9708           and add to it an item stating at least the title, year, new
   9709           authors, and publisher of the Modified Version as given on
   9710           the Title Page.  If there is no section Entitled "History" in
   9711           the Document, create one stating the title, year, authors,
   9712           and publisher of the Document as given on its Title Page,
   9713           then add an item describing the Modified Version as stated in
   9714           the previous sentence.
   9715 
   9716        J. Preserve the network location, if any, given in the Document
   9717           for public access to a Transparent copy of the Document, and
   9718           likewise the network locations given in the Document for
   9719           previous versions it was based on.  These may be placed in
   9720           the "History" section.  You may omit a network location for a
   9721           work that was published at least four years before the
   9722           Document itself, or if the original publisher of the version
   9723           it refers to gives permission.
   9724 
   9725        K. For any section Entitled "Acknowledgements" or "Dedications",
   9726           Preserve the Title of the section, and preserve in the
   9727           section all the substance and tone of each of the contributor
   9728           acknowledgements and/or dedications given therein.
   9729 
   9730        L. Preserve all the Invariant Sections of the Document,
   9731           unaltered in their text and in their titles.  Section numbers
   9732           or the equivalent are not considered part of the section
   9733           titles.
   9734 
   9735        M. Delete any section Entitled "Endorsements".  Such a section
   9736           may not be included in the Modified Version.
   9737 
   9738        N. Do not retitle any existing section to be Entitled
   9739           "Endorsements" or to conflict in title with any Invariant
   9740           Section.
   9741 
   9742        O. Preserve any Warranty Disclaimers.
   9743 
   9744      If the Modified Version includes new front-matter sections or
   9745      appendices that qualify as Secondary Sections and contain no
   9746      material copied from the Document, you may at your option
   9747      designate some or all of these sections as invariant.  To do this,
   9748      add their titles to the list of Invariant Sections in the Modified
   9749      Version's license notice.  These titles must be distinct from any
   9750      other section titles.
   9751 
   9752      You may add a section Entitled "Endorsements", provided it contains
   9753      nothing but endorsements of your Modified Version by various
   9754      parties--for example, statements of peer review or that the text
   9755      has been approved by an organization as the authoritative
   9756      definition of a standard.
   9757 
   9758      You may add a passage of up to five words as a Front-Cover Text,
   9759      and a passage of up to 25 words as a Back-Cover Text, to the end
   9760      of the list of Cover Texts in the Modified Version.  Only one
   9761      passage of Front-Cover Text and one of Back-Cover Text may be
   9762      added by (or through arrangements made by) any one entity.  If the
   9763      Document already includes a cover text for the same cover,
   9764      previously added by you or by arrangement made by the same entity
   9765      you are acting on behalf of, you may not add another; but you may
   9766      replace the old one, on explicit permission from the previous
   9767      publisher that added the old one.
   9768 
   9769      The author(s) and publisher(s) of the Document do not by this
   9770      License give permission to use their names for publicity for or to
   9771      assert or imply endorsement of any Modified Version.
   9772 
   9773   5. COMBINING DOCUMENTS
   9774 
   9775      You may combine the Document with other documents released under
   9776      this License, under the terms defined in section 4 above for
   9777      modified versions, provided that you include in the combination
   9778      all of the Invariant Sections of all of the original documents,
   9779      unmodified, and list them all as Invariant Sections of your
   9780      combined work in its license notice, and that you preserve all
   9781      their Warranty Disclaimers.
   9782 
   9783      The combined work need only contain one copy of this License, and
   9784      multiple identical Invariant Sections may be replaced with a single
   9785      copy.  If there are multiple Invariant Sections with the same name
   9786      but different contents, make the title of each such section unique
   9787      by adding at the end of it, in parentheses, the name of the
   9788      original author or publisher of that section if known, or else a
   9789      unique number.  Make the same adjustment to the section titles in
   9790      the list of Invariant Sections in the license notice of the
   9791      combined work.
   9792 
   9793      In the combination, you must combine any sections Entitled
   9794      "History" in the various original documents, forming one section
   9795      Entitled "History"; likewise combine any sections Entitled
   9796      "Acknowledgements", and any sections Entitled "Dedications".  You
   9797      must delete all sections Entitled "Endorsements."
   9798 
   9799   6. COLLECTIONS OF DOCUMENTS
   9800 
   9801      You may make a collection consisting of the Document and other
   9802      documents released under this License, and replace the individual
   9803      copies of this License in the various documents with a single copy
   9804      that is included in the collection, provided that you follow the
   9805      rules of this License for verbatim copying of each of the
   9806      documents in all other respects.
   9807 
   9808      You may extract a single document from such a collection, and
   9809      distribute it individually under this License, provided you insert
   9810      a copy of this License into the extracted document, and follow
   9811      this License in all other respects regarding verbatim copying of
   9812      that document.
   9813 
   9814   7. AGGREGATION WITH INDEPENDENT WORKS
   9815 
   9816      A compilation of the Document or its derivatives with other
   9817      separate and independent documents or works, in or on a volume of
   9818      a storage or distribution medium, is called an "aggregate" if the
   9819      copyright resulting from the compilation is not used to limit the
   9820      legal rights of the compilation's users beyond what the individual
   9821      works permit.  When the Document is included in an aggregate, this
   9822      License does not apply to the other works in the aggregate which
   9823      are not themselves derivative works of the Document.
   9824 
   9825      If the Cover Text requirement of section 3 is applicable to these
   9826      copies of the Document, then if the Document is less than one half
   9827      of the entire aggregate, the Document's Cover Texts may be placed
   9828      on covers that bracket the Document within the aggregate, or the
   9829      electronic equivalent of covers if the Document is in electronic
   9830      form.  Otherwise they must appear on printed covers that bracket
   9831      the whole aggregate.
   9832 
   9833   8. TRANSLATION
   9834 
   9835      Translation is considered a kind of modification, so you may
   9836      distribute translations of the Document under the terms of section
   9837      4.  Replacing Invariant Sections with translations requires special
   9838      permission from their copyright holders, but you may include
   9839      translations of some or all Invariant Sections in addition to the
   9840      original versions of these Invariant Sections.  You may include a
   9841      translation of this License, and all the license notices in the
   9842      Document, and any Warranty Disclaimers, provided that you also
   9843      include the original English version of this License and the
   9844      original versions of those notices and disclaimers.  In case of a
   9845      disagreement between the translation and the original version of
   9846      this License or a notice or disclaimer, the original version will
   9847      prevail.
   9848 
   9849      If a section in the Document is Entitled "Acknowledgements",
   9850      "Dedications", or "History", the requirement (section 4) to
   9851      Preserve its Title (section 1) will typically require changing the
   9852      actual title.
   9853 
   9854   9. TERMINATION
   9855 
   9856      You may not copy, modify, sublicense, or distribute the Document
   9857      except as expressly provided under this License.  Any attempt
   9858      otherwise to copy, modify, sublicense, or distribute it is void,
   9859      and will automatically terminate your rights under this License.
   9860 
   9861      However, if you cease all violation of this License, then your
   9862      license from a particular copyright holder is reinstated (a)
   9863      provisionally, unless and until the copyright holder explicitly
   9864      and finally terminates your license, and (b) permanently, if the
   9865      copyright holder fails to notify you of the violation by some
   9866      reasonable means prior to 60 days after the cessation.
   9867 
   9868      Moreover, your license from a particular copyright holder is
   9869      reinstated permanently if the copyright holder notifies you of the
   9870      violation by some reasonable means, this is the first time you have
   9871      received notice of violation of this License (for any work) from
   9872      that copyright holder, and you cure the violation prior to 30 days
   9873      after your receipt of the notice.
   9874 
   9875      Termination of your rights under this section does not terminate
   9876      the licenses of parties who have received copies or rights from
   9877      you under this License.  If your rights have been terminated and
   9878      not permanently reinstated, receipt of a copy of some or all of
   9879      the same material does not give you any rights to use it.
   9880 
   9881  10. FUTURE REVISIONS OF THIS LICENSE
   9882 
   9883      The Free Software Foundation may publish new, revised versions of
   9884      the GNU Free Documentation License from time to time.  Such new
   9885      versions will be similar in spirit to the present version, but may
   9886      differ in detail to address new problems or concerns.  See
   9887      `http://www.gnu.org/copyleft/'.
   9888 
   9889      Each version of the License is given a distinguishing version
   9890      number.  If the Document specifies that a particular numbered
   9891      version of this License "or any later version" applies to it, you
   9892      have the option of following the terms and conditions either of
   9893      that specified version or of any later version that has been
   9894      published (not as a draft) by the Free Software Foundation.  If
   9895      the Document does not specify a version number of this License,
   9896      you may choose any version ever published (not as a draft) by the
   9897      Free Software Foundation.  If the Document specifies that a proxy
   9898      can decide which future versions of this License can be used, that
   9899      proxy's public statement of acceptance of a version permanently
   9900      authorizes you to choose that version for the Document.
   9901 
   9902  11. RELICENSING
   9903 
   9904      "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
   9905      World Wide Web server that publishes copyrightable works and also
   9906      provides prominent facilities for anybody to edit those works.  A
   9907      public wiki that anybody can edit is an example of such a server.
   9908      A "Massive Multiauthor Collaboration" (or "MMC") contained in the
   9909      site means any set of copyrightable works thus published on the MMC
   9910      site.
   9911 
   9912      "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
   9913      license published by Creative Commons Corporation, a not-for-profit
   9914      corporation with a principal place of business in San Francisco,
   9915      California, as well as future copyleft versions of that license
   9916      published by that same organization.
   9917 
   9918      "Incorporate" means to publish or republish a Document, in whole or
   9919      in part, as part of another Document.
   9920 
   9921      An MMC is "eligible for relicensing" if it is licensed under this
   9922      License, and if all works that were first published under this
   9923      License somewhere other than this MMC, and subsequently
   9924      incorporated in whole or in part into the MMC, (1) had no cover
   9925      texts or invariant sections, and (2) were thus incorporated prior
   9926      to November 1, 2008.
   9927 
   9928      The operator of an MMC Site may republish an MMC contained in the
   9929      site under CC-BY-SA on the same site at any time before August 1,
   9930      2009, provided the MMC is eligible for relicensing.
   9931 
   9932 
   9933 ADDENDUM: How to use this License for your documents
   9934 ====================================================
   9935 
   9936 To use this License in a document you have written, include a copy of
   9937 the License in the document and put the following copyright and license
   9938 notices just after the title page:
   9939 
   9940        Copyright (C)  YEAR  YOUR NAME.
   9941        Permission is granted to copy, distribute and/or modify this document
   9942        under the terms of the GNU Free Documentation License, Version 1.3
   9943        or any later version published by the Free Software Foundation;
   9944        with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
   9945        Texts.  A copy of the license is included in the section entitled ``GNU
   9946        Free Documentation License''.
   9947 
   9948    If you have Invariant Sections, Front-Cover Texts and Back-Cover
   9949 Texts, replace the "with...Texts." line with this:
   9950 
   9951          with the Invariant Sections being LIST THEIR TITLES, with
   9952          the Front-Cover Texts being LIST, and with the Back-Cover Texts
   9953          being LIST.
   9954 
   9955    If you have Invariant Sections without Cover Texts, or some other
   9956 combination of the three, merge those two alternatives to suit the
   9957 situation.
   9958 
   9959    If your document contains nontrivial examples of program code, we
   9960 recommend releasing these examples in parallel under your choice of
   9961 free software license, such as the GNU General Public License, to
   9962 permit their use in free software.
