1 Introduction

BFD is a package which allows applications to use the same routines to operate on object files whatever the object file format. A new object file format can be supported simply by creating a new BFD back end and adding it to the library.

BFD is split into two parts: the front end, and the back ends (one for each object file format).


1.1 History

One spur behind BFD was the desire, on the part of the GNU 960 team at Intel Oregon, for interoperability of applications on their COFF and b.out file formats. Cygnus was providing GNU support for the team, and was contracted to provide the required functionality.

The name came from a conversation David Wallace was having with Richard Stallman about the library: RMS said that it would be quite hard—David said “BFD”. Stallman was right, but the name stuck.

At the same time, Ready Systems wanted much the same thing, but for different object file formats: IEEE-695, Oasys, Srecords, a.out and 68k coff.

BFD was first implemented by members of Cygnus Support; Steve Chamberlain (sac@cygnus.com), John Gilmore (gnu@cygnus.com), K. Richard Pixley (rich@cygnus.com) and David Henkel-Wallace (gumby@cygnus.com).


1.2 How To Use BFD

To use the library, include bfd.h and link with libbfd.a.

BFD provides a common interface to the parts of an object file for a calling application.

When an application successfully opens a target file (object, archive, or whatever), a pointer to an internal structure is returned. This pointer points to a structure called bfd, described in bfd.h. Our convention is to call this pointer a BFD, and instances of it within code abfd. All operations on the target object file are applied as methods to the BFD. The mapping is defined within bfd.h in a set of macros, all beginning with ‘bfd_’ to reduce namespace pollution.

For example, this sequence does what you would probably expect: return the number of sections in an object file attached to a BFD abfd.

#include "bfd.h"

unsigned int number_of_sections (abfd)
bfd *abfd;
{
  return bfd_count_sections (abfd);
}

The abstraction used within BFD is that an object file has:

Also, BFDs opened for archives have the additional attribute of an index and contain subordinate BFDs. This approach is fine for a.out and coff, but loses efficiency when applied to formats such as S-records and IEEE-695.


1.3 What BFD Version 2 Can Do

When an object file is opened, BFD subroutines automatically determine the format of the input object file. They then build a descriptor in memory with pointers to routines that will be used to access elements of the object file’s data structures.

As different information from the object files is required, BFD reads from different sections of the file and processes them. For example, a very common operation for the linker is processing symbol tables. Each BFD back end provides a routine for converting between the object file’s representation of symbols and an internal canonical format. When the linker asks for the symbol table of an object file, it calls through a memory pointer to the routine from the relevant BFD back end which reads and converts the table into a canonical form. The linker then operates upon the canonical form. When the link is finished and the linker writes the output file’s symbol table, another BFD back end routine is called to take the newly created symbol table and convert it into the chosen output format.


1.3.1 Information Loss

Information can be lost during output. The output formats supported by BFD do not provide identical facilities, and information which can be described in one form has nowhere to go in another format. One example of this is alignment information in b.out. There is nowhere in an a.out format file to store alignment information on the contained data, so when a file is linked from b.out and an a.out image is produced, alignment information will not propagate to the output file. (The linker will still use the alignment information internally, so the link is performed correctly).

Another example is COFF section names. COFF files may contain an unlimited number of sections, each one with a textual section name. If the target of the link is a format which does not have many sections (e.g., a.out) or has sections without names (e.g., the Oasys format), the link cannot be done simply. You can circumvent this problem by describing the desired input-to-output section mapping with the linker command language.

Information can be lost during canonicalization. The BFD internal canonical form of the external formats is not exhaustive; there are structures in input formats for which there is no direct representation internally. This means that the BFD back ends cannot maintain all possible data richness through the transformation between external to internal and back to external formats.

This limitation is only a problem when an application reads one format and writes another. Each BFD back end is responsible for maintaining as much data as possible, and the internal BFD canonical form has structures which are opaque to the BFD core, and exported only to the back ends. When a file is read in one format, the canonical form is generated for BFD and the application. At the same time, the back end saves away any information which may otherwise be lost. If the data is then written back in the same format, the back end routine will be able to use the canonical form provided by the BFD core as well as the information it prepared earlier. Since there is a great deal of commonality between back ends, there is no information lost when linking or copying big endian COFF to little endian COFF, or a.out to b.out. When a mixture of formats is linked, the information is only lost from the files whose format differs from the destination.


1.3.2 The BFD canonical object-file format

The greatest potential for loss of information occurs when there is the least overlap between the information provided by the source format, that stored by the canonical format, and that needed by the destination format. A brief description of the canonical form may help you understand which kinds of data you can count on preserving across conversions.

files

Information stored on a per-file basis includes target machine architecture, particular implementation format type, a demand pageable bit, and a write protected bit. Information like Unix magic numbers is not stored here—only the magic numbers’ meaning, so a ZMAGIC file would have both the demand pageable bit and the write protected text bit set. The byte order of the target is stored on a per-file basis, so that big- and little-endian object files may be used with one another.

sections

Each section in the input file contains the name of the section, the section’s original address in the object file, size and alignment information, various flags, and pointers into other BFD data structures.

symbols

Each symbol contains a pointer to the information for the object file which originally defined it, its name, its value, and various flag bits. When a BFD back end reads in a symbol table, it relocates all symbols to make them relative to the base of the section where they were defined. Doing this ensures that each symbol points to its containing section. Each symbol also has a varying amount of hidden private data for the BFD back end. Since the symbol points to the original file, the private data format for that symbol is accessible. ld can operate on a collection of symbols of wildly different formats without problems.

Normal global and simple local symbols are maintained on output, so an output file (no matter its format) will retain symbols pointing to functions and to global, static, and common variables. Some symbol information is not worth retaining; in a.out, type information is stored in the symbol table as long symbol names. This information would be useless to most COFF debuggers; the linker has command-line switches to allow users to throw it away.

There is one word of type information within the symbol, so if the format supports symbol type information within symbols (for example, COFF, Oasys) and the type is simple enough to fit within one word (nearly everything but aggregates), the information will be preserved.

relocation level

Each canonical BFD relocation record contains a pointer to the symbol to relocate to, the offset of the data to relocate, the section the data is in, and a pointer to a relocation type descriptor. Relocation is performed by passing messages through the relocation type descriptor and the symbol pointer. Therefore, relocations can be performed on output data using a relocation method that is only available in one of the input formats. For instance, Oasys provides a byte relocation format. A relocation record requesting this relocation type would point indirectly to a routine to perform this, so the relocation may be performed on a byte being written to a 68k COFF file, even though 68k COFF has no such relocation type.

line numbers

Object formats can contain, for debugging purposes, some form of mapping between symbols, source line numbers, and addresses in the output file. These addresses have to be relocated along with the symbol information. Each symbol with an associated list of line number records points to the first record of the list. The head of a line number list consists of a pointer to the symbol, which allows finding out the address of the function whose line number is being described. The rest of the list is made up of pairs: offsets into the section and line numbers. Any format which can simply derive this information can pass it successfully between formats.

2.1 typedef bfd

A BFD has type bfd; objects of this type are the cornerstone of any application using BFD. Using BFD consists of making references though the BFD and to data in the BFD.

2.2 Error reporting

Most BFD functions return nonzero on success (check their individual documentation for precise semantics). On an error, they call bfd_set_error to set an error condition that callers can check by calling bfd_get_error. If that returns bfd_error_system_call, then check errno.

The easiest way to report a BFD error to the user is to use bfd_perror.

2.2.1 Type bfd_error_type

The values returned by bfd_get_error are defined by the enumerated type bfd_error_type.


typedef enum bfd_error
{
  bfd_error_no_error = 0,
  bfd_error_system_call,
  bfd_error_invalid_target,
  bfd_error_wrong_format,
  bfd_error_wrong_object_format,
  bfd_error_invalid_operation,
  bfd_error_no_memory,
  bfd_error_no_symbols,
  bfd_error_no_armap,
  bfd_error_no_more_archived_files,
  bfd_error_malformed_archive,
  bfd_error_missing_dso,
  bfd_error_file_not_recognized,
  bfd_error_file_ambiguously_recognized,
  bfd_error_no_contents,
  bfd_error_nonrepresentable_section,
  bfd_error_no_debug_section,
  bfd_error_bad_value,
  bfd_error_file_truncated,
  bfd_error_file_too_big,
  bfd_error_sorry,
  bfd_error_on_input,
  bfd_error_invalid_error_code
}
bfd_error_type;

2.2.1.1 bfd_get_error

Synopsis

bfd_error_type bfd_get_error (void);

Description
Return the current BFD error condition.

2.2.1.2 bfd_set_error

Synopsis

void bfd_set_error (bfd_error_type error_tag);

Description
Set the BFD error condition to be error_tag.

error_tag must not be bfd_error_on_input. Use bfd_set_input_error for input errors instead.

2.2.1.3 bfd_set_input_error

Synopsis

void bfd_set_input_error (bfd *input, bfd_error_type error_tag);

Description
Set the BFD error condition to be bfd_error_on_input. input is the input bfd where the error occurred, and error_tag the bfd_error_type error.

2.2.1.4 bfd_errmsg

Synopsis

const char *bfd_errmsg (bfd_error_type error_tag);

Description
Return a string describing the error error_tag, or the system error if error_tag is bfd_error_system_call.

2.2.1.5 bfd_perror

Synopsis

void bfd_perror (const char *message);

Description
Print to the standard error stream a string describing the last BFD error that occurred, or the last system error if the last BFD error was a system call failure. If message is non-NULL and non-empty, the error string printed is preceded by message, a colon, and a space. It is followed by a newline.

2.2.2 BFD error handler

Some BFD functions want to print messages describing the problem. They call a BFD error handler function. This function may be overridden by the program.

The BFD error handler acts like vprintf.


typedef void (*bfd_error_handler_type) (const char *, va_list);

2.2.2.1 _bfd_error_handler

Synopsis

void _bfd_error_handler (const char *fmt, ...) ATTRIBUTE_PRINTF_1;

Description
This is the default routine to handle BFD error messages. Like fprintf (stderr, ...), but also handles some extra format specifiers.

%pA section name from section. For group components, prints group name too. %pB file name from bfd. For archive components, prints archive too.

Beware: Only supports a maximum of 9 format arguments.

2.2.2.2 bfd_set_error_handler

Synopsis

bfd_error_handler_type bfd_set_error_handler (bfd_error_handler_type);

Description
Set the BFD error handler function. Returns the previous function.

2.2.2.3 _bfd_set_error_handler_caching

Synopsis

bfd_error_handler_type _bfd_set_error_handler_caching (bfd *);

Description
Set the BFD error handler function to one that stores messages to the per_xvec_warn array. Returns the previous function.

2.2.2.4 bfd_set_error_program_name

Synopsis

void bfd_set_error_program_name (const char *);

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

2.2.2.5 _bfd_get_error_program_name

Synopsis

const char *_bfd_get_error_program_name (void);

Description
Get the program name used when printing a BFD error.

2.2.3 BFD assert handler

If BFD finds an internal inconsistency, the bfd assert handler is called with information on the BFD version, BFD source file and line. If this happens, most programs linked against BFD are expected to want to exit with an error, or mark the current BFD operation as failed, so it is recommended to override the default handler, which just calls _bfd_error_handler and continues.


typedef void (*bfd_assert_handler_type) (const char *bfd_formatmsg,
                                         const char *bfd_version,
                                         const char *bfd_file,
                                         int bfd_line);

2.2.3.1 bfd_set_assert_handler

Synopsis

bfd_assert_handler_type bfd_set_assert_handler (bfd_assert_handler_type);

Description
Set the BFD assert handler function. Returns the previous function.


2.3 Miscellaneous

2.3.1 Miscellaneous functions

2.3.1.1 bfd_get_reloc_upper_bound

Synopsis

long bfd_get_reloc_upper_bound (bfd *abfd, asection *sect);

Description
Return the number of bytes required to store the relocation information associated with section sect attached to bfd abfd. If an error occurs, return -1.

2.3.1.2 bfd_canonicalize_reloc

Synopsis

long bfd_canonicalize_reloc
   (bfd *abfd, asection *sec, arelent **loc, asymbol **syms);

Description
Call the back end associated with the open BFD abfd and translate the external form of the relocation information attached to sec into the internal canonical form. Place the table into memory at loc, which has been preallocated, usually by a call to bfd_get_reloc_upper_bound. Returns the number of relocs, or -1 on error.

The syms table is also needed for horrible internal magic reasons.

2.3.1.3 bfd_set_reloc

Synopsis

void bfd_set_reloc
   (bfd *abfd, asection *sec, arelent **rel, unsigned int count);

Description
Set the relocation pointer and count within section sec to the values rel and count. The argument abfd is ignored.

#define bfd_set_reloc(abfd, asect, location, count) \
       BFD_SEND (abfd, _bfd_set_reloc, (abfd, asect, location, count))

2.3.1.4 bfd_set_file_flags

Synopsis

bool bfd_set_file_flags (bfd *abfd, flagword flags);

Description
Set the flag word in the BFD abfd to the value flags.

Possible errors are:

  • bfd_error_wrong_format - The target bfd was not of object format.
  • bfd_error_invalid_operation - The target bfd was open for reading.
  • bfd_error_invalid_operation - The flag word contained a bit which was not applicable to the type of file. E.g., an attempt was made to set the D_PAGED bit on a BFD format which does not support demand paging.

2.3.1.5 bfd_get_arch_size

Synopsis

int bfd_get_arch_size (bfd *abfd);

Description
Returns the normalized architecture address size, in bits, as determined by the object file’s format. By normalized, we mean either 32 or 64. For ELF, this information is included in the header. Use bfd_arch_bits_per_address for number of bits in the architecture address.

Returns
Returns the arch size in bits if known, -1 otherwise.

2.3.1.6 bfd_get_sign_extend_vma

Synopsis

int bfd_get_sign_extend_vma (bfd *abfd);

Description
Indicates if the target architecture "naturally" sign extends an address. Some architectures implicitly sign extend address values when they are converted to types larger than the size of an address. For instance, bfd_get_start_address() will return an address sign extended to fill a bfd_vma when this is the case.

Returns
Returns 1 if the target architecture is known to sign extend addresses, 0 if the target architecture is known to not sign extend addresses, and -1 otherwise.

2.3.1.7 bfd_set_start_address

Synopsis

bool bfd_set_start_address (bfd *abfd, bfd_vma vma);

Description
Make vma the entry point of output BFD abfd.

Returns
Returns TRUE on success, FALSE otherwise.

2.3.1.8 bfd_get_gp_size

Synopsis

unsigned int bfd_get_gp_size (bfd *abfd);

Description
Return the maximum size of objects to be optimized using the GP register under MIPS ECOFF. This is typically set by the -G argument to the compiler, assembler or linker.

2.3.1.9 bfd_set_gp_size

Synopsis

void bfd_set_gp_size (bfd *abfd, unsigned int i);

Description
Set the maximum size of objects to be optimized using the GP register under ECOFF or MIPS ELF. This is typically set by the -G argument to the compiler, assembler or linker.

2.3.1.10 bfd_set_gp_value

Synopsis

void bfd_set_gp_value (bfd *abfd, bfd_vma v);

Description
Allow external access to the fucntion to set the GP value. This is specifically added for gdb-compile support.

2.3.1.11 bfd_scan_vma

Synopsis

bfd_vma bfd_scan_vma (const char *string, const char **end, int base);

Description
Convert, like strtoul, a numerical expression string into a bfd_vma integer, and return that integer. (Though without as many bells and whistles as strtoul.) The expression is assumed to be unsigned (i.e., positive). If given a base, it is used as the base for conversion. A base of 0 causes the function to interpret the string in hex if a leading "0x" or "0X" is found, otherwise in octal if a leading zero is found, otherwise in decimal.

If the value would overflow, the maximum bfd_vma value is returned.

2.3.1.12 bfd_copy_private_header_data

Synopsis

bool bfd_copy_private_header_data (bfd *ibfd, bfd *obfd);

Description
Copy private BFD header information from the BFD ibfd to the the BFD obfd. This copies information that may require sections to exist, but does not require symbol tables. Return true on success, false on error. Possible error returns are:

  • bfd_error_no_memory - Not enough memory exists to create private data for obfd.
#define bfd_copy_private_header_data(ibfd, obfd) \
       BFD_SEND (obfd, _bfd_copy_private_header_data, \
                 (ibfd, obfd))

2.3.1.13 bfd_copy_private_bfd_data

Synopsis

bool bfd_copy_private_bfd_data (bfd *ibfd, bfd *obfd);

Description
Copy private BFD information from the BFD ibfd to the the BFD obfd. Return TRUE on success, FALSE on error. Possible error returns are:

  • bfd_error_no_memory - Not enough memory exists to create private data for obfd.
#define bfd_copy_private_bfd_data(ibfd, obfd) \
       BFD_SEND (obfd, _bfd_copy_private_bfd_data, \
                 (ibfd, obfd))

2.3.1.14 bfd_set_private_flags

Synopsis

bool bfd_set_private_flags (bfd *abfd, flagword flags);

Description
Set private BFD flag information in the BFD abfd. Return TRUE on success, FALSE on error. Possible error returns are:

  • bfd_error_no_memory - Not enough memory exists to create private data for obfd.

2.3.1.20 struct bfd_iovec

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

struct bfd_iovec
{
  /* To avoid problems with macros, a "b" rather than "f"
     prefix is prepended to each method name.  */
  /* Attempt to read/write NBYTES on ABFD's IOSTREAM storing/fetching
     bytes starting at PTR.  Return the number of bytes actually
     transfered (a read past end-of-file returns less than NBYTES),
     or -1 (setting bfd_error) if an error occurs.  */

                  int prot, int flags, file_ptr offset,
                  void **map_addr, bfd_size_type *map_len);
};
extern const struct bfd_iovec _bfd_memory_iovec;

2.3.1.21 bfd_get_mtime

Synopsis

long bfd_get_mtime (bfd *abfd);

Description
Return the file modification time (as read from the file system, or from the archive header for archive members).

2.3.1.22 bfd_get_size

Synopsis

ufile_ptr bfd_get_size (bfd *abfd);

Description
Return the file size (as read from file system) for the file associated with BFD abfd.

The initial motivation for, and use of, this routine is not so we can get the exact size of the object the BFD applies to, since that might not be generally possible (archive members for example). It would be ideal if someone could eventually modify it so that such results were guaranteed.

Instead, we want to ask questions like "is this NNN byte sized object I’m about to try read from file offset YYY reasonable?" As as example of where we might do this, some object formats use string tables for which the first sizeof (long) bytes of the table contain the size of the table itself, including the size bytes. If an application tries to read what it thinks is one of these string tables, without some way to validate the size, and for some reason the size is wrong (byte swapping error, wrong location for the string table, etc.), the only clue is likely to be a read error when it tries to read the table, or a "virtual memory exhausted" error when it tries to allocate 15 bazillon bytes of space for the 15 bazillon byte table it is about to read. This function at least allows us to answer the question, "is the size reasonable?".

A return value of zero indicates the file size is unknown.

2.3.1.23 bfd_get_file_size

Synopsis

ufile_ptr bfd_get_file_size (bfd *abfd);

Description
Return the file size (as read from file system) for the file associated with BFD abfd. It supports both normal files and archive elements.

2.3.1.24 bfd_mmap

Synopsis

void *bfd_mmap (bfd *abfd, void *addr, bfd_size_type len,
    int prot, int flags, file_ptr offset,
    void **map_addr, bfd_size_type *map_len);

Description
Return mmap()ed region of the file, if possible and implemented. LEN and OFFSET do not need to be page aligned. The page aligned address and length are written to MAP_ADDR and MAP_LEN.


2.4 Memory Usage

BFD keeps all of its internal structures in obstacks. There is one obstack per open BFD file, into which the current state is stored. When a BFD is closed, the obstack is deleted, and so everything which has been allocated by BFD for the closing file is thrown away.

BFD does not free anything created by an application, but pointers into bfd structures become invalid on a bfd_close; for example, after a bfd_close the vector passed to bfd_canonicalize_symtab is still around, since it has been allocated by the application, but the data that it pointed to are lost.

The general rule is to not close a BFD until all operations dependent upon data from the BFD have been completed, or all the data from within the file has been copied. To help with the management of memory, there is a function (bfd_alloc_size) which returns the number of bytes in obstacks associated with the supplied BFD. This could be used to select the greediest open BFD, close it to reclaim the memory, perform some operation and reopen the BFD again, to get a fresh copy of the data structures.


2.5 Initialization

2.5.1 Initialization functions

These are the functions that handle initializing a BFD.

2.5.1.1 bfd_init

Synopsis

unsigned int bfd_init (void);

Description
This routine must be called before any other BFD function to initialize magical internal data structures. Returns a magic number, which may be used to check that the bfd library is configured as expected by users.


/* Value returned by bfd_init.  */

#define BFD_INIT_MAGIC (sizeof (struct bfd_section))

2.6 Sections

The raw data contained within a BFD is maintained through the section abstraction. A single BFD may have any number of sections. It keeps hold of them by pointing to the first; each one points to the next in the list.

Sections are supported in BFD in section.c.


2.6.1 Section input

When a BFD is opened for reading, the section structures are created and attached to the BFD.

Each section has a name which describes the section in the outside world—for example, a.out would contain at least three sections, called .text, .data and .bss.

Names need not be unique; for example a COFF file may have several sections named .data.

Sometimes a BFD will contain more than the “natural” number of sections. A back end may attach other sections containing constructor data, or an application may add a section (using bfd_make_section) to the sections attached to an already open BFD. For example, the linker creates an extra section COMMON for each input file’s BFD to hold information about common storage.

The raw data is not necessarily read in when the section descriptor is created. Some targets may leave the data in place until a bfd_get_section_contents call is made. Other back ends may read in all the data at once. For example, an S-record file has to be read once to determine the size of the data.


2.6.2 Section output

To write a new object style BFD, the various sections to be written have to be created. They are attached to the BFD in the same way as input sections; data is written to the sections using bfd_set_section_contents.

Any program that creates or combines sections (e.g., the assembler and linker) must use the asection fields output_section and output_offset to indicate the file sections to which each section must be written. (If the section is being created from scratch, output_section should probably point to the section itself and output_offset should probably be zero.)

The data to be written comes from input sections attached (via output_section pointers) to the output sections. The output section structure can be considered a filter for the input section: the output section determines the vma of the output data and the name, but the input section determines the offset into the output section of the data to be written.

E.g., to create a section "O", starting at 0x100, 0x123 long, containing two subsections, "A" at offset 0x0 (i.e., at vma 0x100) and "B" at offset 0x20 (i.e., at vma 0x120) the asection structures would look like:

   section name          "A"
     output_offset   0x00
     size            0x20
     output_section ----------->  section name    "O"
                             |    vma             0x100
   section name          "B" |    size            0x123
     output_offset   0x20    |
     size            0x103   |
     output_section  --------|

Description
Given sec is a section returned by bfd_get_section_by_name, return the next most recently created section attached to the same BFD with the same name, or if no such section exists in the same BFD and IBFD is non-NULL, the next section with the same name in any input BFD following IBFD. Return NULL on finding no section.

2.6.5.4 bfd_get_linker_section

Synopsis

asection *bfd_get_linker_section (bfd *abfd, const char *name);

   (bfd *abfd,
    const char *name,
    bool (*func) (bfd *abfd, asection *sect, void *obj),
    void *obj);

Description
Call the provided function func for each section attached to the BFD abfd whose name matches name, passing obj as an argument. The function will be called as if by

       func (abfd, the_section, obj);

It returns the first section for which func returns true, otherwise NULL.

2.6.5.6 bfd_get_unique_section_name

Synopsis

char *bfd_get_unique_section_name
   (bfd *abfd, const char *templat, int *count);

Description
Invent a section name that is unique in abfd by tacking a dot and a digit suffix onto the original templat. If count is non-NULL, then it specifies the first number tried as a suffix to generate a unique name. The value pointed to by count will be incremented in this case.

2.6.5.7 bfd_make_section_old_way

Synopsis

asection *bfd_make_section_old_way (bfd *abfd, const char *name);

Description
Create a new empty section called name and attach it to the end of the chain of sections for the BFD abfd. An attempt to create a section with a name which is already in use returns its pointer without changing the section chain.

It has the funny name since this is the way it used to be before it was rewritten....

Possible errors are:

  • bfd_error_invalid_operation - If output has already started for this BFD.
  • bfd_error_no_memory - If memory allocation fails.

2.6.5.8 bfd_make_section_anyway_with_flags

Synopsis

asection *bfd_make_section_anyway_with_flags
   (bfd *abfd, const char *name, flagword flags);

Description
Create a new empty section called name and attach it to the end of the chain of sections for abfd. Create a new section even if there is already a section with that name. Also set the attributes of the new section to the value flags.

Return NULL and set bfd_error on error; possible errors are:

  • bfd_error_invalid_operation - If output has already started for abfd.
  • bfd_error_no_memory - If memory allocation fails.

2.6.5.9 bfd_make_section_anyway

Synopsis

asection *bfd_make_section_anyway (bfd *abfd, const char *name);

Description
Create a new empty section called name and attach it to the end of the chain of sections for abfd. Create a new section even if there is already a section with that name.

Return NULL and set bfd_error on error; possible errors are:

  • bfd_error_invalid_operation - If output has already started for abfd.
  • bfd_error_no_memory - If memory allocation fails.

2.6.5.10 bfd_make_section_with_flags

Synopsis

asection *bfd_make_section_with_flags
   (bfd *, const char *name, flagword flags);

Description
Like bfd_make_section_anyway, but return NULL (without calling bfd_set_error ()) without changing the section chain if there is already a section named name. Also set the attributes of the new section to the value flags. If there is an error, return NULL and set bfd_error.

2.6.5.11 bfd_make_section

Synopsis

asection *bfd_make_section (bfd *, const char *name);

Description
Like bfd_make_section_anyway, but return NULL (without calling bfd_set_error ()) without changing the section chain if there is already a section named name. If there is an error, return NULL and set bfd_error.

2.6.5.12 bfd_set_section_flags

Synopsis

bool bfd_set_section_flags (asection *sec, flagword flags);

Description
Set the attributes of the section sec to the value flags. Return TRUE on success, FALSE on error. Possible error returns are:

  • bfd_error_invalid_operation - The section cannot have one or more of the attributes requested. For example, a .bss section in a.out may not have the SEC_HAS_CONTENTS field set.

2.6.5.13 bfd_rename_section

Synopsis

void bfd_rename_section
   (asection *sec, const char *newname);

Description
Rename section sec to newname.

2.6.5.14 bfd_map_over_sections

Synopsis

void bfd_map_over_sections
   (bfd *abfd,
    void (*func) (bfd *abfd, asection *sect, void *obj),
    void *obj);

Description
Call the provided function func for each section attached to the BFD abfd, passing obj as an argument. The function will be called as if by

       func (abfd, the_section, obj);

This is the preferred method for iterating over sections; an alternative would be to use a loop:

          asection *p;
          for (p = abfd->sections; p != NULL; p = p->next)
             func (abfd, p, ...)

2.6.5.15 bfd_sections_find_if

Synopsis

asection *bfd_sections_find_if
   (bfd *abfd,
    bool (*operation) (bfd *abfd, asection *sect, void *obj),
    void *obj);

Description
Call the provided function operation for each section attached to the BFD abfd, passing obj as an argument. The function will be called as if by

       operation (abfd, the_section, obj);

It returns the first section for which operation returns true.

2.6.5.16 bfd_set_section_size

Synopsis

bool bfd_set_section_size (asection *sec, bfd_size_type val);

Description
Set sec to the size val. If the operation is ok, then TRUE is returned, else FALSE.

Possible error returns:

  • bfd_error_invalid_operation - Writing has started to the BFD, so setting the size is invalid.

2.6.5.17 bfd_set_section_contents

Synopsis

bool bfd_set_section_contents
   (bfd *abfd, asection *section, const void *data,
    file_ptr offset, bfd_size_type count);

Description
Sets the contents of the section section in BFD abfd to the data starting in memory at location. The data is written to the output section starting at offset offset for count octets.

Normally TRUE is returned, but FALSE is returned if there was an error. Possible error returns are:

  • bfd_error_no_contents - The output section does not have the SEC_HAS_CONTENTS attribute, so nothing can be written to it.
  • bfd_error_bad_value - The section is unable to contain all of the data.
  • bfd_error_invalid_operation - The BFD is not writeable.
  • and some more too.

This routine is front end to the back end function _bfd_set_section_contents.

2.6.5.18 bfd_get_section_contents

Synopsis

bool bfd_get_section_contents
   (bfd *abfd, asection *section, void *location, file_ptr offset,
    bfd_size_type count);

Description
Read data from section in BFD abfd into memory starting at location. The data is read at an offset of offset from the start of the input section, and is read for count bytes.

If the contents of a constructor with the SEC_CONSTRUCTOR flag set are requested or if the section does not have the SEC_HAS_CONTENTS flag set, then the location is filled with zeroes. If no errors occur, TRUE is returned, else FALSE.

2.6.5.19 bfd_malloc_and_get_section

Synopsis

bool bfd_malloc_and_get_section
   (bfd *abfd, asection *section, bfd_byte **buf);

Description
Read all data from section in BFD abfd into a buffer, *buf, malloc’d by this function.

2.6.5.20 bfd_copy_private_section_data

Synopsis

bool bfd_copy_private_section_data
   (bfd *ibfd, asection *isec, bfd *obfd, asection *osec);

Description
Copy private section information from isec in the BFD ibfd to the section osec in the BFD obfd. Return TRUE on success, FALSE on error. Possible error returns are:

  • bfd_error_no_memory - Not enough memory exists to create private data for osec.
#define bfd_copy_private_section_data(ibfd, isection, obfd, osection) \
       BFD_SEND (obfd, _bfd_copy_private_section_data, \
                 (ibfd, isection, obfd, osection))

2.6.5.21 bfd_generic_is_group_section

Synopsis

bool bfd_generic_is_group_section (bfd *, const asection *sec);

Description
Returns TRUE if sec is a member of a group.

2.6.5.22 bfd_generic_group_name

Synopsis

const char *bfd_generic_group_name (bfd *, const asection *sec);

Description
Returns group name if sec is a member of a group.

2.6.5.23 bfd_generic_discard_group

Synopsis

bool bfd_generic_discard_group (bfd *abfd, asection *group);

Description
Remove all members of group from the output.

2.6.5.24 _bfd_section_size_insane

Synopsis

bool _bfd_section_size_insane (bfd *abfd, asection *sec);

Description
Returns true if the given section has a size that indicates it cannot be read from file. Return false if the size is OK or* this function can’t say one way or the other.


2.7 Symbols

BFD tries to maintain as much symbol information as it can when it moves information from file to file. BFD passes information to applications though the asymbol structure. When the application requests the symbol table, BFD reads the table in the native form and translates parts of it into the internal format. To maintain more than the information passed to applications, some targets keep some information “behind the scenes” in a structure only the particular back end knows about. For example, the coff back end keeps the original symbol table structure as well as the canonical structure when a BFD is read in. On output, the coff back end can reconstruct the output symbol table so that no information is lost, even information unique to coff which BFD doesn’t know or understand. If a coff symbol table were read, but were written through an a.out back end, all the coff specific information would be lost. The symbol table of a BFD is not necessarily read in until a canonicalize request is made. Then the BFD back end fills in a table provided by the application with pointers to the canonical information. To output symbols, the application provides BFD with a table of pointers to pointers to asymbols. This allows applications like the linker to output a symbol as it was read, since the “behind the scenes” information will be still available.


2.7.1 Reading symbols

There are two stages to reading a symbol table from a BFD: allocating storage, and the actual reading process. This is an excerpt from an application which reads the symbol table:

         long storage_needed;
         asymbol **symbol_table;
         long number_of_symbols;
         long i;

         storage_needed = bfd_get_symtab_upper_bound (abfd);

         if (storage_needed < 0)
           FAIL

         if (storage_needed == 0)
           return;

         symbol_table = xmalloc (storage_needed);
           ...
         number_of_symbols =
            bfd_canonicalize_symtab (abfd, symbol_table);

         if (number_of_symbols < 0)
           FAIL

         for (i = 0; i < number_of_symbols; i++)
           process_symbol (symbol_table[i]);

All storage for the symbols themselves is in an objalloc connected to the BFD; it is freed when the BFD is closed.


2.7.2 Writing symbols

Writing of a symbol table is automatic when a BFD open for writing is closed. The application attaches a vector of pointers to pointers to symbols to the BFD being written, and fills in the symbol count. The close and cleanup code reads through the table provided and performs all the necessary operations. The BFD output code must always be provided with an “owned” symbol: one which has come from another BFD, or one which has been created using bfd_make_empty_symbol. Here is an example showing the creation of a symbol table with only one element:

       #include "sysdep.h"
       #include "bfd.h"
       int main (void)
       {
         bfd *abfd;
         asymbol *ptrs[2];
         asymbol *new;

         abfd = bfd_openw ("foo","a.out-sunos-big");
         bfd_set_format (abfd, bfd_object);
         new = bfd_make_empty_symbol (abfd);
         new->name = "dummy_symbol";
         new->section = bfd_make_section_old_way (abfd, ".text");
         new->flags = BSF_GLOBAL;
         new->value = 0x12345;

         ptrs[0] = new;
         ptrs[1] = 0;

         bfd_set_symtab (abfd, ptrs, 1);
         bfd_close (abfd);
         return 0;
       }

       ./makesym
       nm foo
       00012345 A dummy_symbol

Many formats cannot represent arbitrary symbol information; for instance, the a.out object format does not allow an arbitrary number of sections. A symbol pointing to a section which is not one of .text, .data or .bss cannot be described.


2.7.3 Mini Symbols

Mini symbols provide read-only access to the symbol table. They use less memory space, but require more time to access. They can be useful for tools like nm or objdump, which may have to handle symbol tables of extremely large executables.

The bfd_read_minisymbols function will read the symbols into memory in an internal form. It will return a void * pointer to a block of memory, a symbol count, and the size of each symbol. The pointer is allocated using malloc, and should be freed by the caller when it is no longer needed.

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


2.7.4 typedef asymbol

An asymbol has the form:


typedef struct bfd_symbol
{
  /* A pointer to the BFD which owns the symbol. This information
     is necessary so that a back end can work out what additional
     information (invisible to the application writer) is carried
     with the symbol.

     This field is *almost* redundant, since you can use section->owner
     instead, except that some symbols point to the global sections
     bfd_{abs,com,und}_section.  This could be fixed by making
     these globals be per-bfd (or per-target-flavor).  FIXME.  */

2.7.5 Symbol handling functions

2.7.5.1 bfd_get_symtab_upper_bound

Description
Return the number of bytes required to store a vector of pointers to asymbols for all the symbols in the BFD abfd, including a terminal NULL pointer. If there are no symbols in the BFD, then return 0. If an error occurs, return -1.

#define bfd_get_symtab_upper_bound(abfd) \
       BFD_SEND (abfd, _bfd_get_symtab_upper_bound, (abfd))

2.7.5.2 bfd_is_local_label

Synopsis

bool bfd_is_local_label (bfd *abfd, asymbol *sym);

Description
Return TRUE if the given symbol sym in the BFD abfd is a compiler generated local label, else return FALSE.

2.7.5.3 bfd_is_local_label_name

Synopsis

bool bfd_is_local_label_name (bfd *abfd, const char *name);

Description
Return TRUE if a symbol with the name name in the BFD abfd is a compiler generated local label, else return FALSE. This just checks whether the name has the form of a local label.

#define bfd_is_local_label_name(abfd, name) \
       BFD_SEND (abfd, _bfd_is_local_label_name, (abfd, name))

2.7.5.4 bfd_is_target_special_symbol

Synopsis

bool bfd_is_target_special_symbol (bfd *abfd, asymbol *sym);

Description
Return TRUE iff a symbol sym in the BFD abfd is something special to the particular target represented by the BFD. Such symbols should normally not be mentioned to the user.

#define bfd_is_target_special_symbol(abfd, sym) \
       BFD_SEND (abfd, _bfd_is_target_special_symbol, (abfd, sym))

2.7.5.5 bfd_canonicalize_symtab

Description
Read the symbols from the BFD abfd, and fills in the vector location with pointers to the symbols and a trailing NULL. Return the actual number of symbol pointers, not including the NULL.

#define bfd_canonicalize_symtab(abfd, location) \
       BFD_SEND (abfd, _bfd_canonicalize_symtab, (abfd, location))

2.7.5.6 bfd_set_symtab

Synopsis

Synopsis

void bfd_print_symbol_vandf (bfd *abfd, void *file, asymbol *symbol);

Description
Print the value and flags of the symbol supplied to the stream file.

2.7.5.8 bfd_make_empty_symbol

Description
Create a new asymbol structure for the BFD abfd and return a pointer to it.

This routine is necessary because each back end has private information surrounding the asymbol. Building your own asymbol and pointing to it will not create the private information, and will cause problems later on.

#define bfd_make_empty_symbol(abfd) \
       BFD_SEND (abfd, _bfd_make_empty_symbol, (abfd))

2.7.5.9 _bfd_generic_make_empty_symbol

Synopsis

2.7.5.10 bfd_make_debug_symbol

Description
Create a new asymbol structure for the BFD abfd, to be used as a debugging symbol. Further details of its use have yet to be worked out.

#define bfd_make_debug_symbol(abfd,ptr,size) \
       BFD_SEND (abfd, _bfd_make_debug_symbol, (abfd, ptr, size))

Synopsis

bool bfd_copy_private_symbol_data
   (bfd *ibfd, asymbol *isym, bfd *obfd, asymbol *osym);

Description
Copy private symbol information from isym in the BFD ibfd to the symbol osym in the BFD obfd. Return TRUE on success, FALSE on error. Possible error returns are:

  • bfd_error_no_memory - Not enough memory exists to create private data for osec.
#define bfd_copy_private_symbol_data(ibfd, isymbol, obfd, osymbol) \
       BFD_SEND (obfd, _bfd_copy_private_symbol_data, \
                 (ibfd, isymbol, obfd, osymbol))


2.8 Archives

Description
An archive (or library) is just another BFD. It has a symbol table, although there’s not much a user program will do with it.

The big difference between an archive BFD and an ordinary BFD is that the archive doesn’t have sections. Instead it has a chain of BFDs that are considered its contents. These BFDs can be manipulated like any other. The BFDs contained in an archive opened for reading will all be opened for reading. You may put either input or output BFDs into an archive opened for output; they will be handled correctly when the archive is closed.

Use bfd_openr_next_archived_file to step through the contents of an archive opened for input. You don’t have to read the entire archive if you don’t want to! Read it until you find what you want.

A BFD returned by bfd_openr_next_archived_file can be closed manually with bfd_close. If you do not close it, then a second iteration through the members of an archive may return the same BFD. If you close the archive BFD, then all the member BFDs will automatically be closed as well.

Archive contents of output BFDs are chained through the archive_next pointer in a BFD. The first one is findable through the archive_head slot of the archive. Set it with bfd_set_archive_head (q.v.). A given BFD may be in only one open output archive at a time.

As expected, the BFD archive code is more general than the archive code of any given environment. BFD archives may contain files of different formats (e.g., a.out and coff) and even different architectures. You may even place archives recursively into archives!

This can cause unexpected confusion, since some archive formats are more expressive than others. For instance, Intel COFF archives can preserve long filenames; SunOS a.out archives cannot. If you move a file from the first to the second format and back again, the filename may be truncated. Likewise, different a.out environments have different conventions as to how they truncate filenames, whether they preserve directory names in filenames, etc. When interoperating with native tools, be sure your files are homogeneous.

Beware: most of these formats do not react well to the presence of spaces in filenames. We do the best we can, but can’t always handle this case due to restrictions in the format of archives. Many Unix utilities are braindead in regards to spaces and such in filenames anyway, so this shouldn’t be much of a restriction.

Archives are supported in BFD in archive.c.

2.8.1 Archive functions

2.8.1.1 bfd_get_next_mapent

Synopsis

symindex bfd_get_next_mapent
   (bfd *abfd, symindex previous, carsym **sym);

Description
Step through archive abfd’s symbol table (if it has one). Successively update sym with the next symbol’s information, returning that symbol’s (internal) index into the symbol table.

Supply BFD_NO_MORE_SYMBOLS as the previous entry to get the first one; returns BFD_NO_MORE_SYMBOLS when you’ve already got the last one.

A carsym is a canonical archive symbol. The only user-visible element is its name, a null-terminated string.

2.8.1.2 bfd_set_archive_head

Synopsis

bool bfd_set_archive_head (bfd *output, bfd *new_head);

Description
Set the head of the chain of BFDs contained in the archive output to new_head.

2.8.1.3 bfd_openr_next_archived_file

Synopsis

bfd *bfd_openr_next_archived_file (bfd *archive, bfd *previous);

Description
Provided a BFD, archive, containing an archive and NULL, open an input BFD on the first contained element and returns that. Subsequent calls should pass the archive and the previous return value to return a created BFD to the next contained element. NULL is returned when there are no more. Note - if you want to process the bfd returned by this call be sure to call bfd_check_format() on it first.


2.9 File formats

A format is a BFD concept of high level file contents type. The formats supported by BFD are:

The BFD may contain data, symbols, relocations and debug info.

The BFD contains other BFDs and an optional index.

The BFD contains the result of an executable core dump.

2.9.1 File format functions

2.9.1.1 bfd_check_format

Synopsis

bool bfd_check_format (bfd *abfd, bfd_format format);

Description
Verify if the file attached to the BFD abfd is compatible with the format format (i.e., one of bfd_object, bfd_archive or bfd_core).

If the BFD has been set to a specific target before the call, only the named target and format combination is checked. If the target has not been set, or has been set to default, then all the known target backends is interrogated to determine a match. If the default target matches, it is used. If not, exactly one target must recognize the file, or an error results.

The function returns TRUE on success, otherwise FALSE with one of the following error codes:

  • bfd_error_invalid_operation - if format is not one of bfd_object, bfd_archive or bfd_core.
  • bfd_error_system_call - if an error occured during a read - even some file mismatches can cause bfd_error_system_calls.
  • file_not_recognised - none of the backends recognised the file format.
  • bfd_error_file_ambiguously_recognized - more than one backend recognised the file format.

2.9.1.2 bfd_check_format_matches

Synopsis

bool bfd_check_format_matches
   (bfd *abfd, bfd_format format, char ***matching);

Description
Like bfd_check_format, except when it returns FALSE with bfd_errno set to bfd_error_file_ambiguously_recognized. In that case, if matching is not NULL, it will be filled in with a NULL-terminated list of the names of the formats that matched, allocated with malloc. Then the user may choose a format and try again.

When done with the list that matching points to, the caller should free it.

2.9.1.3 bfd_set_format

Synopsis

bool bfd_set_format (bfd *abfd, bfd_format format);

Description
This function sets the file format of the BFD abfd to the format format. If the target set in the BFD does not support the format requested, the format is invalid, or the BFD is not open for writing, then an error occurs.

2.9.1.4 bfd_format_string

Synopsis

const char *bfd_format_string (bfd_format format);

Description
Return a pointer to a const string invalid, object, archive, core, or unknown, depending upon the value of format.


2.10 Relocations

BFD maintains relocations in much the same way it maintains symbols: they are left alone until required, then read in en-masse and translated into an internal form. A common routine bfd_perform_relocation acts upon the canonical form to do the fixup.

Relocations are maintained on a per section basis, while symbols are maintained on a per BFD basis.

All that a back end has to do to fit the BFD interface is to create a struct reloc_cache_entry for each relocation in a particular section, and fill in the right bits of the structures.


2.10.1 typedef arelent

This is the structure of a relocation entry:


typedef enum bfd_reloc_status
{
  /* No errors detected.  Note - the value 2 is used so that it
     will not be mistaken for the boolean TRUE or FALSE values.  */
  bfd_reloc_ok = 2,

  /* The relocation was performed, but there was an overflow.  */
  bfd_reloc_overflow,

  /* The address to relocate was not within the section supplied.  */
  bfd_reloc_outofrange,

  /* Used by special functions.  */
  bfd_reloc_continue,

  /* Unsupported relocation size requested.  */
  bfd_reloc_notsupported,

  /* Target specific meaning.  */
  bfd_reloc_other,

  /* The symbol to relocate against was undefined.  */
  bfd_reloc_undefined,

  /* The relocation was performed, but may not be ok.  If this type is
     returned, the error_message argument to bfd_perform_relocation
     will be set.  */
  bfd_reloc_dangerous
 }
 bfd_reloc_status_type;

typedef const struct reloc_howto_struct reloc_howto_type;

typedef struct reloc_cache_entry
{
  /* A pointer into the canonical table of pointers.  */
  struct bfd_symbol **sym_ptr_ptr;

  /* offset in section.  */
  bfd_size_type address;

  /* addend for relocation value.  */
  bfd_vma addend;

  /* Pointer to how to perform the required relocation.  */
  reloc_howto_type *howto;

}
arelent;

Description
Here is a description of each of the fields within an arelent:

  • sym_ptr_ptr

The symbol table pointer points to a pointer to the symbol associated with the relocation request. It is the pointer into the table returned by the back end’s canonicalize_symtab action. See Symbols. The symbol is referenced through a pointer to a pointer so that tools like the linker can fix up all the symbols of the same name by modifying only one pointer. The relocation routine looks in the symbol and uses the base of the section the symbol is attached to and the value of the symbol as the initial relocation offset. If the symbol pointer is zero, then the section provided is looked up.

  • address

The address field gives the offset in bytes from the base of the section data which owns the relocation record to the first byte of relocatable information. The actual data relocated will be relative to this point; for example, a relocation type which modifies the bottom two bytes of a four byte word would not touch the first byte pointed to in a big endian world.

  • addend

The addend is a value provided by the back end to be added (!) to the relocation offset. Its interpretation is dependent upon the howto. For example, on the 68k the code:

        char foo[];
        main()
                {
                return foo[0x12345678];
                }

Could be compiled into:

        linkw fp,#-4
        moveb @#12345678,d0
        extbl d0
        unlk fp
        rts

This could create a reloc pointing to foo, but leave the offset in the data, something like:

RELOCATION RECORDS FOR [.text]:
offset   type      value
00000006 32        _foo

00000000 4e56 fffc          ; linkw fp,#-4
00000004 1039 1234 5678     ; moveb @#12345678,d0
0000000a 49c0               ; extbl d0
0000000c 4e5e               ; unlk fp
0000000e 4e75               ; rts

Using coff and an 88k, some instructions don’t have enough space in them to represent the full address range, and pointers have to be loaded in two parts. So you’d get something like:

        or.u     r13,r0,hi16(_foo+0x12345678)
        ld.b     r2,r13,lo16(_foo+0x12345678)
        jmp      r1

This should create two relocs, both pointing to _foo, and with 0x12340000 in their addend field. The data would consist of:

RELOCATION RECORDS FOR [.text]:
offset   type      value
00000002 HVRT16    _foo+0x12340000
00000006 LVRT16    _foo+0x12340000

00000000 5da05678           ; or.u r13,r0,0x5678
00000004 1c4d5678           ; ld.b r2,r13,0x5678
00000008 f400c001           ; jmp r1

The relocation routine digs out the value from the data, adds it to the addend to get the original offset, and then adds the value of _foo. Note that all 32 bits have to be kept around somewhere, to cope with carry from bit 15 to bit 16.

One further example is the sparc and the a.out format. The sparc has a similar problem to the 88k, in that some instructions don’t have room for an entire offset, but on the sparc the parts are created in odd sized lumps. The designers of the a.out format chose to not use the data within the section for storing part of the offset; all the offset is kept within the reloc. Anything in the data should be ignored.

        save %sp,-112,%sp
        sethi %hi(_foo+0x12345678),%g2
        ldsb [%g2+%lo(_foo+0x12345678)],%i0
        ret
        restore

Both relocs contain a pointer to foo, and the offsets contain junk.

RELOCATION RECORDS FOR [.text]:
offset   type      value
00000004 HI22      _foo+0x12345678
00000008 LO10      _foo+0x12345678

00000000 9de3bf90     ; save %sp,-112,%sp
00000004 05000000     ; sethi %hi(_foo+0),%g2
00000008 f048a000     ; ldsb [%g2+%lo(_foo+0)],%i0
0000000c 81c7e008     ; ret
00000010 81e80000     ; restore
  • howto

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

2.10.1.1 enum complain_overflow

Indicates what sort of overflow checking should be done when performing a relocation.


enum complain_overflow
{
  /* Do not complain on overflow.  */
  complain_overflow_dont,

  /* Complain if the value overflows when considered as a signed
     number one bit larger than the field.  ie. A bitfield of N bits
     is allowed to represent -2**n to 2**n-1.  */
  complain_overflow_bitfield,

  /* Complain if the value overflows when considered as a signed
     number.  */
  complain_overflow_signed,

  /* Complain if the value overflows when considered as an
     unsigned number.  */
  complain_overflow_unsigned
};

2.10.1.2 reloc_howto_type

The reloc_howto_type is a structure which contains all the information that libbfd needs to know to tie up a back end’s data.

struct reloc_howto_struct
{
  /* The type field has mainly a documentary use - the back end can
     do what it wants with it, though normally the back end's idea of
     an external reloc number is stored in this field.  */
  unsigned int type;

  /* The size of the item to be relocated in bytes.  */
  unsigned int size:4;

  /* The number of bits in the field to be relocated.  This is used
     when doing overflow checking.  */
  unsigned int bitsize:7;

  /* The value the final relocation is shifted right by.  This drops
     unwanted data from the relocation.  */
  unsigned int rightshift:6;

  /* The bit position of the reloc value in the destination.
     The relocated value is left shifted by this amount.  */
  unsigned int bitpos:6;

  /* What type of overflow error should be checked for when
     relocating.  */
  ENUM_BITFIELD (complain_overflow) complain_on_overflow:2;

  /* The relocation value should be negated before applying.  */
  unsigned int negate:1;

  /* The relocation is relative to the item being relocated.  */
  unsigned int pc_relative:1;

  /* Some formats record a relocation addend in the section contents
     rather than with the relocation.  For ELF formats this is the
     distinction between USE_REL and USE_RELA (though the code checks
     for USE_REL == 1/0).  The value of this field is TRUE if the
     addend is recorded with the section contents; when performing a
     partial link (ld -r) the section contents (the data) will be
     modified.  The value of this field is FALSE if addends are
     recorded with the relocation (in arelent.addend); when performing
     a partial link the relocation will be modified.
     All relocations for all ELF USE_RELA targets should set this field
     to FALSE (values of TRUE should be looked on with suspicion).
     However, the converse is not true: not all relocations of all ELF
     USE_REL targets set this field to TRUE.  Why this is so is peculiar
     to each particular target.  For relocs that aren't used in partial
     links (e.g. GOT stuff) it doesn't matter what this is set to.  */
  unsigned int partial_inplace:1;

  /* When some formats create PC relative instructions, they leave
     the value of the pc of the place being relocated in the offset
     slot of the instruction, so that a PC relative relocation can
     be made just by adding in an ordinary offset (e.g., sun3 a.out).
     Some formats leave the displacement part of an instruction
     empty (e.g., ELF); this flag signals the fact.  */
  unsigned int pcrel_offset:1;

  /* src_mask selects the part of the instruction (or data) to be used
     in the relocation sum.  If the target relocations don't have an
     addend in the reloc, eg. ELF USE_REL, src_mask will normally equal
     dst_mask to extract the addend from the section contents.  If
     relocations do have an addend in the reloc, eg. ELF USE_RELA, this
     field should normally be zero.  Non-zero values for ELF USE_RELA
     targets should be viewed with suspicion as normally the value in
     the dst_mask part of the section contents should be ignored.  */
  bfd_vma src_mask;

  /* dst_mask selects which parts of the instruction (or data) are
     replaced with a relocated value.  */
  bfd_vma dst_mask;

  /* If this field is non null, then the supplied function is
     called rather than the normal function.  This allows really
     strange relocation methods to be accommodated.  */
  bfd_reloc_status_type (*special_function)
    (bfd *, arelent *, struct bfd_symbol *, void *, asection *,
     bfd *, char **);

  /* The textual name of the relocation type.  */
  const char *name;
};

2.10.1.3 The HOWTO Macro

Description
The HOWTO macro fills in a reloc_howto_type (a typedef for const struct reloc_howto_struct).

#define HOWTO_RSIZE(sz) ((sz) < 0 ? -(sz) : (sz))
#define HOWTO(type, right, size, bits, pcrel, left, ovf, func, name,   \
              inplace, src_mask, dst_mask, pcrel_off)                  \
  { (unsigned) type, HOWTO_RSIZE (size), bits, right, left, ovf,       \
    size < 0, pcrel, inplace, pcrel_off, src_mask, dst_mask, func, name }

Description
This is used to fill in an empty howto entry in an array.

#define EMPTY_HOWTO(C) \
  HOWTO ((C), 0, 1, 0, false, 0, complain_overflow_dont, NULL, \
         NULL, false, 0, 0, false)

static inline unsigned int
bfd_get_reloc_size (reloc_howto_type *howto)
{
  return howto->size;
}

2.10.1.4 arelent_chain

Description
How relocs are tied together in an asection:

typedef struct relent_chain
{
  arelent relent;
  struct relent_chain *next;
}
arelent_chain;

2.10.1.5 bfd_check_overflow

Synopsis

bfd_reloc_status_type bfd_check_overflow
   (enum complain_overflow how,
    unsigned int bitsize,
    unsigned int rightshift,
    unsigned int addrsize,
    bfd_vma relocation);

Description
Perform overflow checking on relocation which has bitsize significant bits and will be shifted right by rightshift bits, on a machine with addresses containing addrsize significant bits. The result is either of bfd_reloc_ok or bfd_reloc_overflow.

2.10.1.6 bfd_reloc_offset_in_range

Synopsis

bool bfd_reloc_offset_in_range
   (reloc_howto_type *howto,
    bfd *abfd,
    asection *section,
    bfd_size_type offset);

Description
Returns TRUE if the reloc described by HOWTO can be applied at OFFSET octets in SECTION.

2.10.1.7 bfd_perform_relocation

Synopsis

bfd_reloc_status_type bfd_perform_relocation
   (bfd *abfd,
    arelent *reloc_entry,
    void *data,
    asection *input_section,
    bfd *output_bfd,
    char **error_message);

Description
If output_bfd is supplied to this function, the generated image will be relocatable; the relocations are copied to the output file after they have been changed to reflect the new state of the world. There are two ways of reflecting the results of partial linkage in an output file: by modifying the output data in place, and by modifying the relocation record. Some native formats (e.g., basic a.out and basic coff) have no way of specifying an addend in the relocation type, so the addend has to go in the output data. This is no big deal since in these formats the output data slot will always be big enough for the addend. Complex reloc types with addends were invented to solve just this problem.

2.10.1.8 bfd_install_relocation

Synopsis

bfd_reloc_status_type bfd_install_relocation
   (bfd *abfd,
    arelent *reloc_entry,
    void *data, bfd_vma data_start,
    asection *input_section,
    char **error_message);

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

For now, this function should be considered reserved for the assembler.


2.10.2 The howto manager

When an application wants to create a relocation, but doesn’t know what the target machine might call it, it can find out by using this bit of code.

2.10.2.1 bfd_reloc_code_type

Description
The insides of a reloc code. The idea is that, eventually, there will be one enumerator for every type of relocation we ever do. Pass one of these values to bfd_reloc_type_lookup, and it’ll return a howto pointer.

This does mean that the application must determine the correct enumerator value; you can’t get a howto pointer from a random set of attributes.

Here are the possible values for enum bfd_reloc_code_real:

: BFD_RELOC_64
: BFD_RELOC_32
: BFD_RELOC_26
: BFD_RELOC_24
: BFD_RELOC_16
: BFD_RELOC_14

: BFD_RELOC_24_PCREL
: BFD_RELOC_16_PCREL
: BFD_RELOC_12_PCREL
: BFD_RELOC_8_PCREL

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

: BFD_RELOC_32_SECREL
: BFD_RELOC_16_SECIDX

Section relative relocations. Some targets need this for DWARF2.

: BFD_RELOC_32_PCREL_S2
: BFD_RELOC_16_PCREL_S2
: BFD_RELOC_23_PCREL_S2

These PC-relative relocations are stored as word displacements – i.e., byte displacements shifted right two bits. The 30-bit word displacement (<<32_PCREL_S2>> – 32 bits, shifted 2) is used on the SPARC. (SPARC tools generally refer to this as <<WDISP30>>.) The signed 16-bit displacement is used on the MIPS, and the 23-bit displacement is used on the Alpha.

: BFD_RELOC_HI22
: BFD_RELOC_LO10

High 22 bits and low 10 bits of 32-bit value, placed into lower bits of the target word. These are used on the SPARC.

: BFD_RELOC_GPREL16
: BFD_RELOC_GPREL32

For systems that allocate a Global Pointer register, these are displacements off that register. These relocation types are handled specially, because the value the register will have is decided relatively late.

SPU Relocations.

: BFD_RELOC_ALPHA_GPDISP_HI16

Alpha ECOFF and ELF relocations. Some of these treat the symbol or "addend" in some special way. For GPDISP_HI16 ("gpdisp") relocations, the symbol is ignored when writing; when reading, it will be the absolute section symbol. The addend is the displacement in bytes of the "lda" instruction from the "ldah" instruction (which is at the address of this reloc).

: BFD_RELOC_ALPHA_GPDISP_LO16

For GPDISP_LO16 ("ignore") relocations, the symbol is handled as with GPDISP_HI16 relocs. The addend is ignored when writing the relocations out, and is filled in with the file’s GP value on reading, for convenience.

: BFD_RELOC_ALPHA_GPDISP

The ELF GPDISP relocation is exactly the same as the GPDISP_HI16 relocation except that there is no accompanying GPDISP_LO16 relocation.

: BFD_RELOC_ALPHA_LITERAL
: BFD_RELOC_ALPHA_ELF_LITERAL
: BFD_RELOC_ALPHA_LITUSE

The Alpha LITERAL/LITUSE relocs are produced by a symbol reference; the assembler turns it into a LDQ instruction to load the address of the symbol, and then fills in a register in the real instruction.

The LITERAL reloc, at the LDQ instruction, refers to the .lita section symbol. The addend is ignored when writing, but is filled in with the file’s GP value on reading, for convenience, as with the GPDISP_LO16 reloc.

The ELF_LITERAL reloc is somewhere between 16_GOTOFF and GPDISP_LO16. It should refer to the symbol to be referenced, as with 16_GOTOFF, but it generates output not based on the position within the .got section, but relative to the GP value chosen for the file during the final link stage.

The LITUSE reloc, on the instruction using the loaded address, gives information to the linker that it might be able to use to optimize away some literal section references. The symbol is ignored (read as the absolute section symbol), and the "addend" indicates the type of instruction using the register: 1 - "memory" fmt insn 2 - byte-manipulation (byte offset reg) 3 - jsr (target of branch)

: BFD_RELOC_ALPHA_HINT

The HINT relocation indicates a value that should be filled into the "hint" field of a jmp/jsr/ret instruction, for possible branch- prediction logic which may be provided on some processors.

: BFD_RELOC_ALPHA_LINKAGE

The LINKAGE relocation outputs a linkage pair in the object file, which is filled by the linker.

: BFD_RELOC_ALPHA_CODEADDR

The CODEADDR relocation outputs a STO_CA in the object file, which is filled by the linker.

: BFD_RELOC_ALPHA_GPREL_HI16
: BFD_RELOC_ALPHA_GPREL_LO16

The GPREL_HI/LO relocations together form a 32-bit offset from the GP register.

: BFD_RELOC_ALPHA_BRSGP

Like BFD_RELOC_23_PCREL_S2, except that the source and target must share a common GP, and the target address is adjusted for STO_ALPHA_STD_GPLOAD.

: BFD_RELOC_ALPHA_NOP

The NOP relocation outputs a NOP if the longword displacement between two procedure entry points is < 2^21.

: BFD_RELOC_ALPHA_BSR

The BSR relocation outputs a BSR if the longword displacement between two procedure entry points is < 2^21.

: BFD_RELOC_ALPHA_LDA

The LDA relocation outputs a LDA if the longword displacement between two procedure entry points is < 2^16.

: BFD_RELOC_ALPHA_BOH

The BOH relocation outputs a BSR if the longword displacement between two procedure entry points is < 2^21, or else a hint.

PowerPC and PowerPC64 thread-local storage relocations.

: BFD_RELOC_I370_D12

IBM 370/390 relocations

: BFD_RELOC_CTOR

The type of reloc used to build a constructor table - at the moment probably a 32 bit wide absolute relocation, but the target can choose. It generally does map to one of the other relocation types.

: BFD_RELOC_ARM_PCREL_BRANCH

ARM 26 bit pc-relative branch. The lowest two bits must be zero and are not stored in the instruction.

: BFD_RELOC_ARM_PCREL_BLX

ARM 26 bit pc-relative branch. The lowest bit must be zero and is not stored in the instruction. The 2nd lowest bit comes from a 1 bit field in the instruction.

: BFD_RELOC_THUMB_PCREL_BLX

Thumb 22 bit pc-relative branch. The lowest bit must be zero and is not stored in the instruction. The 2nd lowest bit comes from a 1 bit field in the instruction.

: BFD_RELOC_ARM_PCREL_CALL

ARM 26-bit pc-relative branch for an unconditional BL or BLX instruction.

: BFD_RELOC_ARM_PCREL_JUMP

ARM 26-bit pc-relative branch for B or conditional BL instruction.

: BFD_RELOC_THUMB_PCREL_BRANCH5

ARM 5-bit pc-relative branch for Branch Future instructions.

: BFD_RELOC_THUMB_PCREL_BRANCH25

Thumb 7-, 9-, 12-, 20-, 23-, and 25-bit pc-relative branches. The lowest bit must be zero and is not stored in the instruction. Note that the corresponding ELF R_ARM_THM_JUMPnn constant has an "nn" one smaller in all cases. Note further that BRANCH23 corresponds to R_ARM_THM_CALL.

: BFD_RELOC_ARM_OFFSET_IMM

12-bit immediate offset, used in ARM-format ldr and str instructions.

: BFD_RELOC_ARM_THUMB_OFFSET

5-bit immediate offset, used in Thumb-format ldr and str instructions.

: BFD_RELOC_ARM_TARGET1

Pc-relative or absolute relocation depending on target. Used for entries in .init_array sections.

: BFD_RELOC_ARM_ROSEGREL32

Read-only segment base relative address.

: BFD_RELOC_ARM_SBREL32

Data segment base relative address.

: BFD_RELOC_ARM_TARGET2

This reloc is used for references to RTTI data from exception handling tables. The actual definition depends on the target. It may be a pc-relative or some form of GOT-indirect relocation.

: BFD_RELOC_ARM_PREL31

31-bit PC relative address.

: BFD_RELOC_VTABLE_INHERIT
: BFD_RELOC_VTABLE_ENTRY

These two relocations are used by the linker to determine which of the entries in a C++ virtual function table are actually used. When the –gc-sections option is given, the linker will zero out the entries that are not used, so that the code for those functions need not be included in the output.

VTABLE_INHERIT is a zero-space relocation used to describe to the linker the inheritance tree of a C++ virtual function table. The relocation’s symbol should be the parent class’ vtable, and the relocation should be located at the child vtable.

VTABLE_ENTRY is a zero-space relocation that describes the use of a virtual function table entry. The reloc’s symbol should refer to the table of the class mentioned in the code. Off of that base, an offset describes the entry that is being used. For Rela hosts, this offset is stored in the reloc’s addend. For Rel hosts, we are forced to put this offset in the reloc’s section offset.

Description
Return TRUE if the core file attached to core_bfd was generated by a run of the executable file attached to exec_bfd, FALSE otherwise.

2.11.1.5 generic_core_file_matches_executable_p

Synopsis

bool generic_core_file_matches_executable_p
   (bfd *core_bfd, bfd *exec_bfd);

Description
Return TRUE if the core file attached to core_bfd was generated by a run of the executable file attached to exec_bfd. The match is based on executable basenames only.

Note: When not able to determine the core file failing command or the executable name, we still return TRUE even though we’re not sure that core file and executable match. This is to avoid generating a false warning in situations where we really don’t know whether they match or not.


2.12 Targets

Description
Each port of BFD to a different machine requires the creation of a target back end. All the back end provides to the root part of BFD is a structure containing pointers to functions which perform certain low level operations on files. BFD translates the applications’s requests through a pointer into calls to the back end routines.

When a file is opened with bfd_openr, its format and target are unknown. BFD uses various mechanisms to determine how to interpret the file. The operations performed are:

Once the BFD has been opened and the target selected, the file format may be determined. This is done by calling bfd_check_format on the BFD with a suggested format. If target_defaulted has been set, each possible target type is tried to see if it recognizes the specified format. bfd_check_format returns TRUE when the caller guesses right.


2.12.1 bfd_target

Description
This structure contains everything that BFD knows about a target. It includes things like its byte order, name, and which routines to call to do various operations.

Every BFD points to a target structure with its xvec member.

The macros below are used to dispatch to functions through the bfd_target vector. They are used in a number of macros further down in bfd.h, and are also used when calling various routines by hand inside the BFD implementation. The arglist argument must be parenthesized; it contains all the arguments to the called function.

They make the documentation (more) unpleasant to read, so if someone wants to fix this and not break the above, please do.

#define BFD_SEND(bfd, message, arglist) \
  ((*((bfd)->xvec->message)) arglist)

#ifdef DEBUG_BFD_SEND
#undef BFD_SEND
#define BFD_SEND(bfd, message, arglist) \
  (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
    ((*((bfd)->xvec->message)) arglist) : \
    (bfd_assert (__FILE__,__LINE__), NULL))
#endif

For operations which index on the BFD format:

#define BFD_SEND_FMT(bfd, message, arglist) \
  (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist)

#ifdef DEBUG_BFD_SEND
#undef BFD_SEND_FMT
#define BFD_SEND_FMT(bfd, message, arglist) \
  (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
   (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist) : \
   (bfd_assert (__FILE__,__LINE__), NULL))
#endif

/* Defined to TRUE if unused section symbol should be kept.  */
#ifndef TARGET_KEEP_UNUSED_SECTION_SYMBOLS
#define TARGET_KEEP_UNUSED_SECTION_SYMBOLS true
#endif

This is the structure which defines the type of BFD this is. The xvec member of the struct bfd itself points here. Each module that implements access to a different target under BFD, defines one of these.

FIXME, these names should be rationalised with the names of the entry points which call them. Too bad we can’t have one macro to define them both!

2.12.1.1 _bfd_per_xvec_warn

Synopsis

struct per_xvec_message **_bfd_per_xvec_warn (const bfd_target *, size_t);

Description
Return a location for the given target xvec to use for warnings specific to that target. If TARG is NULL, returns the array of per_xvec_message pointers, otherwise if ALLOC is zero, returns a pointer to a pointer to the list of messages for TARG, otherwise (both TARG and ALLOC non-zero), allocates a new per_xvec_message with space for a string of ALLOC bytes and returns a pointer to a pointer to it. May return a pointer to a NULL pointer on allocation failure.

2.12.1.2 bfd_set_default_target

Synopsis

bool bfd_set_default_target (const char *name);

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

2.12.1.3 bfd_find_target

Synopsis

const bfd_target *bfd_find_target (const char *target_name, bfd *abfd);

Description
Return a pointer to the transfer vector for the object target named target_name. If target_name is NULL, choose the one in the environment variable GNUTARGET; if that is null or not defined, then choose the first entry in the target list. Passing in the string "default" or setting the environment variable to "default" will cause the first entry in the target list to be returned, and "target_defaulted" will be set in the BFD if abfd isn’t NULL. This causes bfd_check_format to loop over all the targets to find the one that matches the file being read.

2.12.1.4 bfd_get_target_info

Synopsis

const bfd_target *bfd_get_target_info (const char *target_name,
    bfd *abfd,
    bool *is_bigendian,
    int *underscoring,
    const char **def_target_arch);

Description
Return a pointer to the transfer vector for the object target named target_name. If target_name is NULL, choose the one in the environment variable GNUTARGET; if that is null or not defined, then choose the first entry in the target list. Passing in the string "default" or setting the environment variable to "default" will cause the first entry in the target list to be returned, and "target_defaulted" will be set in the BFD if abfd isn’t NULL. This causes bfd_check_format to loop over all the targets to find the one that matches the file being read. If is_bigendian is not NULL, then set this value to target’s endian mode. True for big-endian, FALSE for little-endian or for invalid target. If underscoring is not NULL, then set this value to target’s underscoring mode. Zero for none-underscoring, -1 for invalid target, else the value of target vector’s symbol underscoring. If def_target_arch is not NULL, then set it to the architecture string specified by the target_name.

2.12.1.5 bfd_target_list

Synopsis

const char ** bfd_target_list (void);

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

2.12.1.6 bfd_iterate_over_targets

Synopsis

const bfd_target *bfd_iterate_over_targets
   (int (*func) (const bfd_target *, void *),
    void *data);

Description
Call func for each target in the list of BFD target vectors, passing data to func. Stop iterating if func returns a non-zero result, and return that target vector. Return NULL if func always returns zero.

2.12.1.7 bfd_flavour_name

Synopsis

const char *bfd_flavour_name (enum bfd_flavour flavour);

Description
Return the string form of flavour.


2.13 Architectures

BFD keeps one atom in a BFD describing the architecture of the data attached to the BFD: a pointer to a bfd_arch_info_type.

Pointers to structures can be requested independently of a BFD so that an architecture’s information can be interrogated without access to an open BFD.

The architecture information is provided by each architecture package. The set of default architectures is selected by the macro SELECT_ARCHITECTURES. This is normally set up in the config/target.mt file of your choice. If the name is not defined, then all the architectures supported are included.

When BFD starts up, all the architectures are called with an initialize method. It is up to the architecture back end to insert as many items into the list of architectures as it wants to; generally this would be one for each machine and one for the default case (an item with a machine field of 0).

BFD’s idea of an architecture is implemented in archures.c.

2.13.1 bfd_architecture

Description
This enum gives the object file’s CPU architecture, in a global sense—i.e., what processor family does it belong to? Another field indicates which processor within the family is in use. The machine gives a number which distinguishes different versions of the architecture, containing, for example, 68020 for Motorola 68020.

2.14 Opening and closing BFDs

2.14.1 Functions for opening and closing

2.14.1.1 bfd_fopen

Synopsis

bfd *bfd_fopen (const char *filename, const char *target,
    const char *mode, int fd);

Description
Open the file filename with the target target. Return a pointer to the created BFD. If fd is not -1, then fdopen is used to open the file; otherwise, fopen is used. mode is passed directly to fopen or fdopen.

Calls bfd_find_target, so target is interpreted as by that function.

The new BFD is marked as cacheable iff fd is -1.

If NULL is returned then an error has occured. Possible errors are bfd_error_no_memory, bfd_error_invalid_target or system_call error.

On error, fd is always closed.

A copy of the filename argument is stored in the newly created BFD. It can be accessed via the bfd_get_filename() macro.

2.14.1.2 bfd_openr

Synopsis

bfd *bfd_openr (const char *filename, const char *target);

Description
Open the file filename (using fopen) with the target target. Return a pointer to the created BFD.

Calls bfd_find_target, so target is interpreted as by that function.

If NULL is returned then an error has occured. Possible errors are bfd_error_no_memory, bfd_error_invalid_target or system_call error.

A copy of the filename argument is stored in the newly created BFD. It can be accessed via the bfd_get_filename() macro.

2.14.1.3 bfd_fdopenr

Synopsis

bfd *bfd_fdopenr (const char *filename, const char *target, int fd);

Description
bfd_fdopenr is to bfd_fopenr much like fdopen is to fopen. It opens a BFD on a file already described by the fd supplied.

When the file is later bfd_closed, the file descriptor will be closed. If the caller desires that this file descriptor be cached by BFD (opened as needed, closed as needed to free descriptors for other opens), with the supplied fd used as an initial file descriptor (but subject to closure at any time), call bfd_set_cacheable(bfd, 1) on the returned BFD. The default is to assume no caching; the file descriptor will remain open until bfd_close, and will not be affected by BFD operations on other files.

Possible errors are bfd_error_no_memory, bfd_error_invalid_target and bfd_error_system_call.

On error, fd is closed.

A copy of the filename argument is stored in the newly created BFD. It can be accessed via the bfd_get_filename() macro.

2.14.1.4 bfd_fdopenw

Synopsis

bfd *bfd_fdopenw (const char *filename, const char *target, int fd);

Description
bfd_fdopenw is exactly like bfd_fdopenr with the exception that the resulting BFD is suitable for output.

2.14.1.5 bfd_openstreamr

Synopsis

bfd *bfd_openstreamr (const char * filename, const char * target,
    void * stream);

Description
Open a BFD for read access on an existing stdio stream. When the BFD is passed to bfd_close, the stream will be closed.

A copy of the filename argument is stored in the newly created BFD. It can be accessed via the bfd_get_filename() macro.

2.14.1.6 bfd_openr_iovec

Synopsis

bfd *bfd_openr_iovec (const char *filename, const char *target,
    void *(*open_func) (struct bfd *nbfd,
    void *open_closure),
    void *open_closure,
    file_ptr (*pread_func) (struct bfd *nbfd,
    void *stream,
    void *buf,
    file_ptr nbytes,
    file_ptr offset),
    int (*close_func) (struct bfd *nbfd,
    void *stream),
    int (*stat_func) (struct bfd *abfd,
    void *stream,
    struct stat *sb));

Description
Create and return a BFD backed by a read-only stream. The stream is created using open_func, accessed using pread_func and destroyed using close_func.

Calls bfd_find_target, so target is interpreted as by that function.

Calls open_func (which can call bfd_zalloc and bfd_get_filename) to obtain the read-only stream backing the BFD. open_func either succeeds returning the non-NULL stream, or fails returning NULL (setting bfd_error).

Calls pread_func to request nbytes of data from stream starting at offset (e.g., via a call to bfd_read). pread_func either succeeds returning the number of bytes read (which can be less than nbytes when end-of-file), or fails returning -1 (setting bfd_error).

Calls close_func when the BFD is later closed using bfd_close. close_func either succeeds returning 0, or fails returning -1 (setting bfd_error).

Calls stat_func to fill in a stat structure for bfd_stat, bfd_get_size, and bfd_get_mtime calls. stat_func returns 0 on success, or returns -1 on failure (setting bfd_error).

If bfd_openr_iovec returns NULL then an error has occurred. Possible errors are bfd_error_no_memory, bfd_error_invalid_target and bfd_error_system_call.

A copy of the filename argument is stored in the newly created BFD. It can be accessed via the bfd_get_filename() macro.

2.14.1.7 bfd_openw

Synopsis

bfd *bfd_openw (const char *filename, const char *target);

Description
Create a BFD, associated with file filename, using the file format target, and return a pointer to it.

Possible errors are bfd_error_system_call, bfd_error_no_memory, bfd_error_invalid_target.

A copy of the filename argument is stored in the newly created BFD. It can be accessed via the bfd_get_filename() macro.

2.14.1.8 bfd_close

Synopsis

bool bfd_close (bfd *abfd);

Description
Close a BFD. If the BFD was open for writing, then pending operations are completed and the file written out and closed. If the created file is executable, then chmod is called to mark it as such.

All memory attached to the BFD is released.

The file descriptor associated with the BFD is closed (even if it was passed in to BFD by bfd_fdopenr).

Returns
TRUE is returned if all is ok, otherwise FALSE.

2.14.1.9 bfd_close_all_done

Synopsis

bool bfd_close_all_done (bfd *);

Description
Close a BFD. Differs from bfd_close since it does not complete any pending operations. This routine would be used if the application had just used BFD for swapping and didn’t want to use any of the writing code.

If the created file is executable, then chmod is called to mark it as such.

All memory attached to the BFD is released.

Returns
TRUE is returned if all is ok, otherwise FALSE.

2.14.1.10 bfd_create

Synopsis

bfd *bfd_create (const char *filename, bfd *templ);

Description
Create a new BFD in the manner of bfd_openw, but without opening a file. The new BFD takes the target from the target used by templ. The format is always set to bfd_object.

A copy of the filename argument is stored in the newly created BFD. It can be accessed via the bfd_get_filename() macro.

2.14.1.11 bfd_make_writable

Synopsis

bool bfd_make_writable (bfd *abfd);

Description
Takes a BFD as created by bfd_create and converts it into one like as returned by bfd_openw. It does this by converting the BFD to BFD_IN_MEMORY. It’s assumed that you will call bfd_make_readable on this bfd later.

Returns
TRUE is returned if all is ok, otherwise FALSE.

2.14.1.12 bfd_make_readable

Synopsis

bool bfd_make_readable (bfd *abfd);

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

Returns
TRUE is returned if all is ok, otherwise FALSE.

2.14.1.13 bfd_alloc

Synopsis

void *bfd_alloc (bfd *abfd, bfd_size_type wanted);

Description
Allocate a block of wanted bytes of memory attached to abfd and return a pointer to it.

2.14.1.14 bfd_zalloc

Synopsis

void *bfd_zalloc (bfd *abfd, bfd_size_type wanted);

Description
Allocate a block of wanted bytes of zeroed memory attached to abfd and return a pointer to it.

2.14.1.19 separate_debug_file_exists

Synopsis

bool separate_debug_file_exists
   (char *name, void *crc32_p);

Description
Checks to see if name is a file and if its contents match crc32, which is a pointer to an unsigned long containing a CRC32.

The crc32_p parameter is an untyped pointer because this routine is used as a check_func_type function.

2.14.1.20 separate_alt_debug_file_exists

Synopsis

bool separate_alt_debug_file_exists
   (char *name, void *unused);

Description
Checks to see if name is a file.

2.14.1.21 find_separate_debug_file

Synopsis

char *find_separate_debug_file
   (bfd *abfd, const char *dir, bool include_dirs,
    get_func_type get, check_func_type check, void *data);

Description
Searches for a debug information file corresponding to abfd.

The name of the separate debug info file is returned by the get function. This function scans various fixed locations in the filesystem, including the file tree rooted at dir. If the include_dirs parameter is true then the directory components of abfd’s filename will be included in the searched locations.

data is passed unmodified to the get and check functions. It is generally used to implement build-id-like matching in the callback functions.

Returns
Returns the filename of the first file to be found which receives a TRUE result from the check function. Returns NULL if no valid file could be found.

2.14.1.26 get_build_id

Synopsis

struct bfd_build_id * get_build_id (bfd *abfd);

Description
Finds the build-id associated with abfd. If the build-id is extracted from the note section then a build-id structure is built for it, using memory allocated to abfd, and this is then attached to the abfd.

Returns
Returns a pointer to the build-id structure if a build-id could be found. If no build-id is found NULL is returned and error code is set.

2.14.1.27 get_build_id_name

Synopsis

char * get_build_id_name (bfd *abfd, void *build_id_out_p)

Description
Searches abfd for a build-id, and then constructs a pathname from it. The path is computed as .build-id/NN/NN+NN.debug where NNNN+NN is the build-id value as a hexadecimal string.

Returns
Returns the constructed filename or NULL upon error. It is the caller’s responsibility to free the memory used to hold the filename. If a filename is returned then the build_id_out_p parameter (which points to a struct bfd_build_id pointer) is set to a pointer to the build_id structure.

2.14.1.28 check_build_id_file

Synopsis

bool check_build_id_file (char *name, void *buildid_p);

Description
Checks to see if name is a readable file and if its build-id matches buildid.

Returns
Returns TRUE if the file exists, is readable, and contains a build-id which matches the build-id pointed at by build_id_p (which is really a struct bfd_build_id **).

2.14.1.30 bfd_set_filename

Synopsis

const char *bfd_set_filename (bfd *abfd, const char *filename);

Description
Set the filename of abfd, copying the FILENAME parameter to bfd_alloc’d memory owned by abfd. Returns a pointer the newly allocated name, or NULL if the allocation failed.


Internal


2.15 File caching

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

2.15.1 Caching functions

2.15.1.1 bfd_cache_init

Synopsis

bool bfd_cache_init (bfd *abfd);

Description
Add a newly opened BFD to the cache.

2.15.1.2 bfd_cache_close

Synopsis

bool bfd_cache_close (bfd *abfd);

Description
Remove the BFD abfd from the cache. If the attached file is open, then close it too.

Returns
FALSE is returned if closing the file fails, TRUE is returned if all is well.

2.15.1.3 bfd_cache_close_all

Synopsis

bool bfd_cache_close_all (void);

Description
Remove all BFDs from the cache. If the attached file is open, then close it too.

Returns
FALSE is returned if closing one of the file fails, TRUE is returned if all is well.

2.15.1.4 bfd_open_file

Synopsis

FILE* bfd_open_file (bfd *abfd);

Description
Call the OS to open a file for abfd. Return the FILE * (possibly NULL) that results from this operation. Set up the BFD so that future accesses know the file is open. If the FILE * returned is NULL, then it won’t have been put in the cache, so it won’t have to be removed from it.


2.16 Linker Functions

The linker uses three special entry points in the BFD target vector. It is not necessary to write special routines for these entry points when creating a new BFD back end, since generic versions are provided. However, writing them can speed up linking and make it use significantly less runtime memory.

The first routine creates a hash table used by the other routines. The second routine adds the symbols from an object file to the hash table. The third routine takes all the object files and links them together to create the output file. These routines are designed so that the linker proper does not need to know anything about the symbols in the object files that it is linking. The linker merely arranges the sections as directed by the linker script and lets BFD handle the details of symbols and relocs.

The second routine and third routines are passed a pointer to a struct bfd_link_info structure (defined in bfdlink.h) which holds information relevant to the link, including the linker hash table (which was created by the first routine) and a set of callback functions to the linker proper.

The generic linker routines are in linker.c, and use the header file genlink.h. As of this writing, the only back ends which have implemented versions of these routines are a.out (in aoutx.h) and ECOFF (in ecoff.c). The a.out routines are used as examples throughout this section.


2.16.1 Creating a linker hash table

The linker routines must create a hash table, which must be derived from struct bfd_link_hash_table described in bfdlink.c. See Hash Tables, for information on how to create a derived hash table. This entry point is called using the target vector of the linker output file.

The _bfd_link_hash_table_create entry point must allocate and initialize an instance of the desired hash table. If the back end does not require any additional information to be stored with the entries in the hash table, the entry point may simply create a struct bfd_link_hash_table. Most likely, however, some additional information will be needed.

For example, with each entry in the hash table the a.out linker keeps the index the symbol has in the final output file (this index number is used so that when doing a relocatable link the symbol index used in the output file can be quickly filled in when copying over a reloc). The a.out linker code defines the required structures and functions for a hash table derived from struct bfd_link_hash_table. The a.out linker hash table is created by the function NAME(aout,link_hash_table_create); it simply allocates space for the hash table, initializes it, and returns a pointer to it.

When writing the linker routines for a new back end, you will generally not know exactly which fields will be required until you have finished. You should simply create a new hash table which defines no additional fields, and then simply add fields as they become necessary.


2.16.2 Adding symbols to the hash table

The linker proper will call the _bfd_link_add_symbols entry point for each object file or archive which is to be linked (typically these are the files named on the command line, but some may also come from the linker script). The entry point is responsible for examining the file. For an object file, BFD must add any relevant symbol information to the hash table. For an archive, BFD must determine which elements of the archive should be used and adding them to the link.

The a.out version of this entry point is NAME(aout,link_add_symbols).


2.16.2.1 Differing file formats

Normally all the files involved in a link will be of the same format, but it is also possible to link together different format object files, and the back end must support that. The _bfd_link_add_symbols entry point is called via the target vector of the file to be added. This has an important consequence: the function may not assume that the hash table is the type created by the corresponding _bfd_link_hash_table_create vector. All the _bfd_link_add_symbols function can assume about the hash table is that it is derived from struct bfd_link_hash_table.

Sometimes the _bfd_link_add_symbols function must store some information in the hash table entry to be used by the _bfd_final_link function. In such a case the output bfd xvec must be checked to make sure that the hash table was created by an object file of the same format.

The _bfd_final_link routine must be prepared to handle a hash entry without any extra information added by the _bfd_link_add_symbols function. A hash entry without extra information will also occur when the linker script directs the linker to create a symbol. Note that, regardless of how a hash table entry is added, all the fields will be initialized to some sort of null value by the hash table entry initialization function.

See ecoff_link_add_externals for an example of how to check the output bfd before saving information (in this case, the ECOFF external symbol debugging information) in a hash table entry.


2.16.2.2 Adding symbols from an object file

When the _bfd_link_add_symbols routine is passed an object file, it must add all externally visible symbols in that object file to the hash table. The actual work of adding the symbol to the hash table is normally handled by the function _bfd_generic_link_add_one_symbol. The _bfd_link_add_symbols routine is responsible for reading all the symbols from the object file and passing the correct information to _bfd_generic_link_add_one_symbol.

The _bfd_link_add_symbols routine should not use bfd_canonicalize_symtab to read the symbols. The point of providing this routine is to avoid the overhead of converting the symbols into generic asymbol structures.

_bfd_generic_link_add_one_symbol handles the details of combining common symbols, warning about multiple definitions, and so forth. It takes arguments which describe the symbol to add, notably symbol flags, a section, and an offset. The symbol flags include such things as BSF_WEAK or BSF_INDIRECT. The section is a section in the object file, or something like bfd_und_section_ptr for an undefined symbol or bfd_com_section_ptr for a common symbol.

If the _bfd_final_link routine is also going to need to read the symbol information, the _bfd_link_add_symbols routine should save it somewhere attached to the object file BFD. However, the information should only be saved if the keep_memory field of the info argument is TRUE, so that the -no-keep-memory linker switch is effective.

The a.out function which adds symbols from an object file is aout_link_add_object_symbols, and most of the interesting work is in aout_link_add_symbols. The latter saves pointers to the hash tables entries created by _bfd_generic_link_add_one_symbol indexed by symbol number, so that the _bfd_final_link routine does not have to call the hash table lookup routine to locate the entry.


2.16.2.3 Adding symbols from an archive

When the _bfd_link_add_symbols routine is passed an archive, it must look through the symbols defined by the archive and decide which elements of the archive should be included in the link. For each such element it must call the add_archive_element linker callback, and it must add the symbols from the object file to the linker hash table. (The callback may in fact indicate that a replacement BFD should be used, in which case the symbols from that BFD should be added to the linker hash table instead.)

In most cases the work of looking through the symbols in the archive should be done by the _bfd_generic_link_add_archive_symbols function. _bfd_generic_link_add_archive_symbols is passed a function to call to make the final decision about adding an archive element to the link and to do the actual work of adding the symbols to the linker hash table. If the element is to be included, the add_archive_element linker callback routine must be called with the element as an argument, and the element’s symbols must be added to the linker hash table just as though the element had itself been passed to the _bfd_link_add_symbols function.

When the a.out _bfd_link_add_symbols function receives an archive, it calls _bfd_generic_link_add_archive_symbols passing aout_link_check_archive_element as the function argument. aout_link_check_archive_element calls aout_link_check_ar_symbols. If the latter decides to add the element (an element is only added if it provides a real, non-common, definition for a previously undefined or common symbol) it calls the add_archive_element callback and then aout_link_check_archive_element calls aout_link_add_symbols to actually add the symbols to the linker hash table - possibly those of a substitute BFD, if the add_archive_element callback avails itself of that option.

The ECOFF back end is unusual in that it does not normally call _bfd_generic_link_add_archive_symbols, because ECOFF archives already contain a hash table of symbols. The ECOFF back end searches the archive itself to avoid the overhead of creating a new hash table.


2.17 Hash Tables

BFD provides a simple set of hash table functions. Routines are provided to initialize a hash table, to free a hash table, to look up a string in a hash table and optionally create an entry for it, and to traverse a hash table. There is currently no routine to delete an string from a hash table.

The basic hash table does not permit any data to be stored with a string. However, a hash table is designed to present a base class from which other types of hash tables may be derived. These derived types may store additional information with the string. Hash tables were implemented in this way, rather than simply providing a data pointer in a hash table entry, because they were designed for use by the linker back ends. The linker may create thousands of hash table entries, and the overhead of allocating private data and storing and following pointers becomes noticeable.

The basic hash table code is in hash.c.


2.17.1 Creating and freeing a hash table

To create a hash table, create an instance of a struct bfd_hash_table (defined in bfd.h) and call bfd_hash_table_init (if you know approximately how many entries you will need, the function bfd_hash_table_init_n, which takes a size argument, may be used). bfd_hash_table_init returns FALSE if some sort of error occurs.

The function bfd_hash_table_init take as an argument a function to use to create new entries. For a basic hash table, use the function bfd_hash_newfunc. See Deriving a new hash table type, for why you would want to use a different value for this argument.

bfd_hash_table_init will create an objalloc which will be used to allocate new entries. You may allocate memory on this objalloc using bfd_hash_allocate.

Use bfd_hash_table_free to free up all the memory that has been allocated for a hash table. This will not free up the struct bfd_hash_table itself, which you must provide.

Use bfd_hash_set_default_size to set the default size of hash table to use.


2.17.2 Looking up or entering a string

The function bfd_hash_lookup is used both to look up a string in the hash table and to create a new entry.

If the create argument is FALSE, bfd_hash_lookup will look up a string. If the string is found, it will returns a pointer to a struct bfd_hash_entry. If the string is not found in the table bfd_hash_lookup will return NULL. You should not modify any of the fields in the returns struct bfd_hash_entry.

If the create argument is TRUE, the string will be entered into the hash table if it is not already there. Either way a pointer to a struct bfd_hash_entry will be returned, either to the existing structure or to a newly created one. In this case, a NULL return means that an error occurred.

If the create argument is TRUE, and a new entry is created, the copy argument is used to decide whether to copy the string onto the hash table objalloc or not. If copy is passed as FALSE, you must be careful not to deallocate or modify the string as long as the hash table exists.


2.17.3 Traversing a hash table

The function bfd_hash_traverse may be used to traverse a hash table, calling a function on each element. The traversal is done in a random order.

bfd_hash_traverse takes as arguments a function and a generic void * pointer. The function is called with a hash table entry (a struct bfd_hash_entry *) and the generic pointer passed to bfd_hash_traverse. The function must return a boolean value, which indicates whether to continue traversing the hash table. If the function returns FALSE, bfd_hash_traverse will stop the traversal and return immediately.


2.17.4 Deriving a new hash table type

Many uses of hash tables want to store additional information which each entry in the hash table. Some also find it convenient to store additional information with the hash table itself. This may be done using a derived hash table.

Since C is not an object oriented language, creating a derived hash table requires sticking together some boilerplate routines with a few differences specific to the type of hash table you want to create.

An example of a derived hash table is the linker hash table. The structures for this are defined in bfdlink.h. The functions are in linker.c.

You may also derive a hash table from an already derived hash table. For example, the a.out linker backend code uses a hash table derived from the linker hash table.


2.17.4.1 Define the derived structures

You must define a structure for an entry in the hash table, and a structure for the hash table itself.

The first field in the structure for an entry in the hash table must be of the type used for an entry in the hash table you are deriving from. If you are deriving from a basic hash table this is struct bfd_hash_entry, which is defined in bfd.h. The first field in the structure for the hash table itself must be of the type of the hash table you are deriving from itself. If you are deriving from a basic hash table, this is struct bfd_hash_table.

For example, the linker hash table defines struct bfd_link_hash_entry (in bfdlink.h). The first field, root, is of type struct bfd_hash_entry. Similarly, the first field in struct bfd_link_hash_table, table, is of type struct bfd_hash_table.


2.17.4.2 Write the derived creation routine

You must write a routine which will create and initialize an entry in the hash table. This routine is passed as the function argument to bfd_hash_table_init.

In order to permit other hash tables to be derived from the hash table you are creating, this routine must be written in a standard way.

The first argument to the creation routine is a pointer to a hash table entry. This may be NULL, in which case the routine should allocate the right amount of space. Otherwise the space has already been allocated by a hash table type derived from this one.

After allocating space, the creation routine must call the creation routine of the hash table type it is derived from, passing in a pointer to the space it just allocated. This will initialize any fields used by the base hash table.

Finally the creation routine must initialize any local fields for the new hash table type.

Here is a boilerplate example of a creation routine. function_name is the name of the routine. entry_type is the type of an entry in the hash table you are creating. base_newfunc is the name of the creation routine of the hash table type your hash table is derived from.

struct bfd_hash_entry *
function_name (struct bfd_hash_entry *entry,
                     struct bfd_hash_table *table,
                     const char *string)
{
  struct entry_type *ret = (entry_type *) entry;

 /* Allocate the structure if it has not already been allocated by a
    derived class.  */
  if (ret == NULL)
    {
      ret = bfd_hash_allocate (table, sizeof (* ret));
      if (ret == NULL)
        return NULL;
    }

 /* Call the allocation method of the base class.  */
  ret = ((entry_type *)
         base_newfunc ((struct bfd_hash_entry *) ret, table, string));

 /* Initialize the local fields here.  */

  return (struct bfd_hash_entry *) ret;
}

Description
The creation routine for the linker hash table, which is in linker.c, looks just like this example. function_name is _bfd_link_hash_newfunc. entry_type is struct bfd_link_hash_entry. base_newfunc is bfd_hash_newfunc, the creation routine for a basic hash table.

_bfd_link_hash_newfunc also initializes the local fields in a linker hash table entry: type, written and next.


2.17.4.3 Write other derived routines

You will want to write other routines for your new hash table, as well.

You will want an initialization routine which calls the initialization routine of the hash table you are deriving from and initializes any other local fields. For the linker hash table, this is _bfd_link_hash_table_init in linker.c.

You will want a lookup routine which calls the lookup routine of the hash table you are deriving from and casts the result. The linker hash table uses bfd_link_hash_lookup in linker.c (this actually takes an additional argument which it uses to decide how to return the looked up value).

You may want a traversal routine. This should just call the traversal routine of the hash table you are deriving from with appropriate casts. The linker hash table uses bfd_link_hash_traverse in linker.c.

These routines may simply be defined as macros. For example, the a.out backend linker hash table, which is derived from the linker hash table, uses macros for the lookup and traversal routines. These are aout_link_hash_lookup and aout_link_hash_traverse in aoutx.h.


3 BFD back ends


3.1 What to Put Where

All of BFD lives in one directory.


3.2 a.out backends

Description
BFD supports a number of different flavours of a.out format, though the major differences are only the sizes of the structures on disk, and the shape of the relocation information.

The support is split into a basic support file aoutx.h and other files which derive functions from the base. One derivation file is aoutf1.h (for a.out flavour 1), and adds to the basic a.out functions support for sun3, sun4, and 386 a.out files, to create a target jump vector for a specific target.

This information is further split out into more specific files for each machine, including sunos.c for sun3 and sun4, and demo64.c for a demonstration of a 64 bit a.out format.

The base file aoutx.h defines general mechanisms for reading and writing records to and from disk and various other methods which BFD requires. It is included by aout32.c and aout64.c to form the names aout_32_swap_exec_header_in, aout_64_swap_exec_header_in, etc.

As an example, this is what goes on to make the back end for a sun4, from aout32.c:

       #define ARCH_SIZE 32
       #include "aoutx.h"

Which exports names:

       ...
       aout_32_canonicalize_reloc
       aout_32_find_nearest_line
       aout_32_get_lineno
       aout_32_get_reloc_upper_bound
       ...

from sunos.c:

       #define TARGET_NAME "a.out-sunos-big"
       #define VECNAME    sparc_aout_sunos_be_vec
       #include "aoutf1.h"

requires all the names from aout32.c, and produces the jump vector

       sparc_aout_sunos_be_vec

The file host-aout.c is a special case. It is for a large set of hosts that use “more or less standard” a.out files, and for which cross-debugging is not interesting. It uses the standard 32-bit a.out support routines, but determines the file offsets and addresses of the text, data, and BSS sections, the machine architecture and machine type, and the entry point address, in a host-dependent manner. Once these values have been determined, generic code is used to handle the object file.

When porting it to run on a new system, you must supply:

        HOST_PAGE_SIZE
        HOST_SEGMENT_SIZE
        HOST_MACHINE_ARCH       (optional)
        HOST_MACHINE_MACHINE    (optional)
        HOST_TEXT_START_ADDR
        HOST_STACK_END_ADDR

in the file ../include/sys/h-XXX.h (for your host). These values, plus the structures and macros defined in a.out.h on your host system, will produce a BFD target that will access ordinary a.out files on your host. To configure a new machine to use host-aout.c, specify:

       TDEFAULTS = -DDEFAULT_VECTOR=host_aout_big_vec
       TDEPFILES= host-aout.o trad-core.o

in the config/XXX.mt file, and modify configure.ac to use the XXX.mt file (by setting "bfd_target=XXX") when your configuration is selected.

3.2.1 Relocations

Description
The file aoutx.h provides for both the standard and extended forms of a.out relocation records.

The standard records contain only an address, a symbol index, and a type field. The extended records also have a full integer for an addend.

3.2.2 Internal entry points

Description
aoutx.h exports several routines for accessing the contents of an a.out file, which are gathered and exported in turn by various format specific files (eg sunos.c).

3.2.2.1 aout_size_swap_exec_header_in

Synopsis

void aout_size_swap_exec_header_in,
   (bfd *abfd,
    struct external_exec *bytes,
    struct internal_exec *execp);

Description
Swap the information in an executable header raw_bytes taken from a raw byte stream memory image into the internal exec header structure execp.

3.2.2.2 aout_size_swap_exec_header_out

Synopsis

void aout_size_swap_exec_header_out
   (bfd *abfd,
    struct internal_exec *execp,
    struct external_exec *raw_bytes);

Description
Swap the information in an internal exec header structure execp into the buffer raw_bytes ready for writing to disk.

3.2.2.3 aout_size_some_aout_object_p

   (bfd *abfd,
    struct internal_exec *execp,
    bfd_cleanup (*callback_to_real_object_p) (bfd *));

Description
Some a.out variant thinks that the file open in abfd checking is an a.out file. Do some more checking, and set up for access if it really is. Call back to the calling environment’s "finish up" function just before returning, to handle any last-minute setup.

3.2.2.4 aout_size_mkobject

Synopsis

bool aout_size_mkobject, (bfd *abfd);

Description
Initialize BFD abfd for use with a.out files.

3.2.2.5 aout_size_machine_type

Synopsis

enum machine_type  aout_size_machine_type
   (enum bfd_architecture arch,
    unsigned long machine,
    bool *unknown);

Description
Keep track of machine architecture and machine type for a.out’s. Return the machine_type for a particular architecture and machine, or M_UNKNOWN if that exact architecture and machine can’t be represented in a.out format.

If the architecture is understood, machine type 0 (default) is always understood.

3.2.2.6 aout_size_set_arch_mach

Synopsis

bool aout_size_set_arch_mach,
   (bfd *,
    enum bfd_architecture arch,
    unsigned long machine);

Description

   (bfd *abfd,
    asection *newsect);

Description
Called by the BFD in response to a bfd_make_section request.


3.3 coff backends

BFD supports a number of different flavours of coff format. The major differences between formats are the sizes and alignments of fields in structures on disk, and the occasional extra field.

Coff in all its varieties is implemented with a few common files and a number of implementation specific files. For example, the i386 coff format is implemented in the file coff-i386.c. This file #includes coff/i386.h which defines the external structure of the coff format for the i386, and coff/internal.h which defines the internal structure. coff-i386.c also defines the relocations used by the i386 coff format See Relocations.

3.3.1 Porting to a new version of coff

The recommended method is to select from the existing implementations the version of coff which is most like the one you want to use. For example, we’ll say that i386 coff is the one you select, and that your coff flavour is called foo. Copy i386coff.c to foocoff.c, copy ../include/coff/i386.h to ../include/coff/foo.h, and add the lines to targets.c and Makefile.in so that your new back end is used. Alter the shapes of the structures in ../include/coff/foo.h so that they match what you need. You will probably also have to add #ifdefs to the code in coff/internal.h and coffcode.h if your version of coff is too wild.

You can verify that your new BFD backend works quite simply by building objdump from the binutils directory, and making sure that its version of what’s going on and your host system’s idea (assuming it has the pretty standard coff dump utility, usually called att-dump or just dump) are the same. Then clean up your code, and send what you’ve done to Cygnus. Then your stuff will be in the next release, and you won’t have to keep integrating it.

3.3.2 How the coff backend works

3.3.2.1 File layout

The Coff backend is split into generic routines that are applicable to any Coff target and routines that are specific to a particular target. The target-specific routines are further split into ones which are basically the same for all Coff targets except that they use the external symbol format or use different values for certain constants.

The generic routines are in coffgen.c. These routines work for any Coff target. They use some hooks into the target specific code; the hooks are in a bfd_coff_backend_data structure, one of which exists for each target.

The essentially similar target-specific routines are in coffcode.h. This header file includes executable C code. The various Coff targets first include the appropriate Coff header file, make any special defines that are needed, and then include coffcode.h.

Some of the Coff targets then also have additional routines in the target source file itself.

3.3.2.2 Coff long section names

In the standard Coff object format, section names are limited to the eight bytes available in the s_name field of the SCNHDR section header structure. The format requires the field to be NUL-padded, but not necessarily NUL-terminated, so the longest section names permitted are a full eight characters.

The Microsoft PE variants of the Coff object file format add an extension to support the use of long section names. This extension is defined in section 4 of the Microsoft PE/COFF specification (rev 8.1). If a section name is too long to fit into the section header’s s_name field, it is instead placed into the string table, and the s_name field is filled with a slash ("/") followed by the ASCII decimal representation of the offset of the full name relative to the string table base.

Note that this implies that the extension can only be used in object files, as executables do not contain a string table. The standard specifies that long section names from objects emitted into executable images are to be truncated.

However, as a GNU extension, BFD can generate executable images that contain a string table and long section names. This would appear to be technically valid, as the standard only says that Coff debugging information is deprecated, not forbidden, and in practice it works, although some tools that parse PE files expecting the MS standard format may become confused; PEview is one known example.

The functionality is supported in BFD by code implemented under the control of the macro COFF_LONG_SECTION_NAMES. If not defined, the format does not support long section names in any way. If defined, it is used to initialise a flag, _bfd_coff_long_section_names, and a hook function pointer, _bfd_coff_set_long_section_names, in the Coff backend data structure. The flag controls the generation of long section names in output BFDs at runtime; if it is false, as it will be by default when generating an executable image, long section names are truncated; if true, the long section names extension is employed. The hook points to a function that allows the value of the flag to be altered at runtime, on formats that support long section names at all; on other formats it points to a stub that returns an error indication.

With input BFDs, the flag is set according to whether any long section names are detected while reading the section headers. For a completely new BFD, the flag is set to the default for the target format. This information can be used by a client of the BFD library when deciding what output format to generate, and means that a BFD that is opened for read and subsequently converted to a writeable BFD and modified in-place will retain whatever format it had on input.

If COFF_LONG_SECTION_NAMES is simply defined (blank), or is defined to the value "1", then long section names are enabled by default; if it is defined to the value zero, they are disabled by default (but still accepted in input BFDs). The header coffcode.h defines a macro, COFF_DEFAULT_LONG_SECTION_NAMES, which is used in the backends to initialise the backend data structure fields appropriately; see the comments for further detail.

3.3.2.3 Bit twiddling

Each flavour of coff supported in BFD has its own header file describing the external layout of the structures. There is also an internal description of the coff layout, in coff/internal.h. A major function of the coff backend is swapping the bytes and twiddling the bits to translate the external form of the structures into the normal internal form. This is all performed in the bfd_swap_thing_direction routines. Some elements are different sizes between different versions of coff; it is the duty of the coff version specific include file to override the definitions of various packing routines in coffcode.h. E.g., the size of line number entry in coff is sometimes 16 bits, and sometimes 32 bits. #defineing PUT_LNSZ_LNNO and GET_LNSZ_LNNO will select the correct one. No doubt, some day someone will find a version of coff which has a varying field size not catered to at the moment. To port BFD, that person will have to add more #defines. Three of the bit twiddling routines are exported to gdb; coff_swap_aux_in, coff_swap_sym_in and coff_swap_lineno_in. GDB reads the symbol table on its own, but uses BFD to fix things up. More of the bit twiddlers are exported for gas; coff_swap_aux_out, coff_swap_sym_out, coff_swap_lineno_out, coff_swap_reloc_out, coff_swap_filehdr_out, coff_swap_aouthdr_out, coff_swap_scnhdr_out. Gas currently keeps track of all the symbol table and reloc drudgery itself, thereby saving the internal BFD overhead, but uses BFD to swap things on the way out, making cross ports much safer. Doing so also allows BFD (and thus the linker) to use the same header files as gas, which makes one avenue to disaster disappear.

3.3.2.4 Symbol reading

The simple canonical form for symbols used by BFD is not rich enough to keep all the information available in a coff symbol table. The back end gets around this problem by keeping the original symbol table around, "behind the scenes".

When a symbol table is requested (through a call to bfd_canonicalize_symtab), a request gets through to coff_get_normalized_symtab. This reads the symbol table from the coff file and swaps all the structures inside into the internal form. It also fixes up all the pointers in the table (represented in the file by offsets from the first symbol in the table) into physical pointers to elements in the new internal table. This involves some work since the meanings of fields change depending upon context: a field that is a pointer to another structure in the symbol table at one moment may be the size in bytes of a structure at the next. Another pass is made over the table. All symbols which mark file names (C_FILE symbols) are modified so that the internal string points to the value in the auxent (the real filename) rather than the normal text associated with the symbol (".file").

At this time the symbol names are moved around. Coff stores all symbols less than nine characters long physically within the symbol table; longer strings are kept at the end of the file in the string table. This pass moves all strings into memory and replaces them with pointers to the strings.

The symbol table is massaged once again, this time to create the canonical table used by the BFD application. Each symbol is inspected in turn, and a decision made (using the sclass field) about the various flags to set in the asymbol. See Symbols. The generated canonical table shares strings with the hidden internal symbol table.

Any linenumbers are read from the coff file too, and attached to the symbols which own the functions the linenumbers belong to.

3.3.2.5 Symbol writing

Writing a symbol to a coff file which didn’t come from a coff file will lose any debugging information. The asymbol structure remembers the BFD from which the symbol was taken, and on output the back end makes sure that the same destination target as source target is present.

When the symbols have come from a coff file then all the debugging information is preserved.

Symbol tables are provided for writing to the back end in a vector of pointers to pointers. This allows applications like the linker to accumulate and output large symbol tables without having to do too much byte copying.

This function runs through the provided symbol table and patches each symbol marked as a file place holder (C_FILE) to point to the next file place holder in the list. It also marks each offset field in the list with the offset from the first symbol of the current symbol.

Another function of this procedure is to turn the canonical value form of BFD into the form used by coff. Internally, BFD expects symbol values to be offsets from a section base; so a symbol physically at 0x120, but in a section starting at 0x100, would have the value 0x20. Coff expects symbols to contain their final value, so symbols have their values changed at this point to reflect their sum with their owning section. This transformation uses the output_section field of the asymbol’s asection See Sections.

  • coff_mangle_symbols

This routine runs though the provided symbol table and uses the offsets generated by the previous pass and the pointers generated when the symbol table was read in to create the structured hierarchy required by coff. It changes each pointer to a symbol into the index into the symbol table of the asymbol.

  • coff_write_symbols

This routine runs through the symbol table and patches up the symbols from their internal form into the coff way, calls the bit twiddlers, and writes out the table to the file.

3.3.2.8 Writing relocations

To write relocations, the back end steps though the canonical relocation table and create an internal_reloc. The symbol index to use is removed from the offset field in the symbol table supplied. The address comes directly from the sum of the section base address and the relocation offset; the type is dug directly from the howto field. Then the internal_reloc is swapped into the shape of an external_reloc and written out to disk.

3.3.2.9 Reading linenumbers

Creating the linenumber table is done by reading in the entire coff linenumber table, and creating another table for internal use.

A coff linenumber table is structured so that each function is marked as having a line number of 0. Each line within the function is an offset from the first line in the function. The base of the line number information for the table is stored in the symbol associated with the function.

Note: The PE format uses line number 0 for a flag indicating a new source file.

The information is copied from the external to the internal table, and each symbol which marks a function is marked by pointing its...

How does this work ?

3.3.2.10 Reading relocations

Coff relocations are easily transformed into the internal BFD form (arelent).

Reading a coff relocation table is done in the following stages:

  • Read the entire coff relocation table into memory.
  • Process each relocation in turn; first swap it from the external to the internal form.
  • Turn the symbol referenced in the relocation’s symbol index into a pointer into the canonical symbol table. This table is the same as the one returned by a call to bfd_canonicalize_symtab. The back end will call that routine and save the result if a canonicalization hasn’t been done.
  • The reloc index is turned into a pointer to a howto structure, in a back end specific way. For instance, the 386 uses the r_type to directly produce an index into a howto table vector.

3.4 ELF backends

BFD support for ELF formats is being worked on. Currently, the best supported back ends are for sparc and i386 (running svr4 or Solaris 2).

Documentation of the internals of the support code still needs to be written. The code is changing quickly enough that we haven’t bothered yet.


3.5 mmo backend

The mmo object format is used exclusively together with Professor Donald E. Knuth’s educational 64-bit processor MMIX. The simulator mmix which is available at http://mmix.cs.hm.edu/src/index.html understands this format. That package also includes a combined assembler and linker called mmixal. The mmo format has no advantages feature-wise compared to e.g. ELF. It is a simple non-relocatable object format with no support for archives or debugging information, except for symbol value information and line numbers (which is not yet implemented in BFD). See http://mmix.cs.hm.edu/ for more information about MMIX. The ELF format is used for intermediate object files in the BFD implementation.


3.5.1 File layout

The mmo file contents is not partitioned into named sections as with e.g. ELF. Memory areas is formed by specifying the location of the data that follows. Only the memory area ‘0x0000…00’ to ‘0x01ff…ff’ is executable, so it is used for code (and constants) and the area ‘0x2000…00’ to ‘0x20ff…ff’ is used for writable data. See mmo section mapping.

There is provision for specifying “special data” of 65536 different types. We use type 80 (decimal), arbitrarily chosen the same as the ELF e_machine number for MMIX, filling it with section information normally found in ELF objects. See mmo section mapping.

Contents is entered as 32-bit words, xor:ed over previous contents, always zero-initialized. A word that starts with the byte ‘0x98’ forms a command called a ‘lopcode’, where the next byte distinguished between the thirteen lopcodes. The two remaining bytes, called the ‘Y’ and ‘Z’ fields, or the ‘YZ’ field (a 16-bit big-endian number), are used for various purposes different for each lopcode. As documented in http://mmix.cs.hm.edu/doc/mmixal.pdf, the lopcodes are:

lop_quote

0x98000001. The next word is contents, regardless of whether it starts with 0x98 or not.

lop_loc

0x9801YYZZ, where ‘Z’ is 1 or 2. This is a location directive, setting the location for the next data to the next 32-bit word (for Z = 1) or 64-bit word (for Z = 2), plus Y * 2^56. Normally ‘Y’ is 0 for the text segment and 2 for the data segment. Beware that the low bits of non- tetrabyte-aligned values are silently discarded when being automatically incremented and when storing contents (in contrast to e.g. its use as current location when followed by lop_fixo et al before the next possibly-quoted tetrabyte contents).

lop_skip

0x9802YYZZ. Increase the current location by ‘YZ’ bytes.

lop_fixo

0x9803YYZZ, where ‘Z’ is 1 or 2. Store the current location as 64 bits into the location pointed to by the next 32-bit (Z = 1) or 64-bit (Z = 2) word, plus Y * 2^56.

lop_fixr

0x9804YYZZ. ‘YZ’ is stored into the current location plus 2 - 4 * YZ.

lop_fixrx

0x980500ZZ. ‘Z’ is 16 or 24. A value ‘L’ derived from the following 32-bit word are used in a manner similar to ‘YZ’ in lop_fixr: it is xor:ed into the current location minus 4 * L. The first byte of the word is 0 or 1. If it is 1, then L = (lowest 24 bits of word) - 2^Z, if 0, then L = (lowest 24 bits of word).

lop_file

0x9806YYZZ. ‘Y’ is the file number, ‘Z’ is count of 32-bit words. Set the file number to ‘Y’ and the line counter to 0. The next Z * 4 bytes contain the file name, padded with zeros if the count is not a multiple of four. The same ‘Y’ may occur multiple times, but ‘Z’ must be 0 for all but the first occurrence.

lop_line

0x9807YYZZ. ‘YZ’ is the line number. Together with lop_file, it forms the source location for the next 32-bit word. Note that for each non-lopcode 32-bit word, line numbers are assumed incremented by one.

lop_spec

0x9808YYZZ. ‘YZ’ is the type number. Data until the next lopcode other than lop_quote forms special data of type ‘YZ’. See mmo section mapping.

Other types than 80, (or type 80 with a content that does not parse) is stored in sections named .MMIX.spec_data.n where n is the ‘YZ’-type. The flags for such a sections say not to allocate or load the data. The vma is 0. Contents of multiple occurrences of special data n is concatenated to the data of the previous lop_spec ns. The location in data or code at which the lop_spec occurred is lost.

lop_pre

0x980901ZZ. The first lopcode in a file. The ‘Z’ field forms the length of header information in 32-bit words, where the first word tells the time in seconds since ‘00:00:00 GMT Jan 1 1970’.

lop_post

0x980a00ZZ. Z > 32. This lopcode follows after all content-generating lopcodes in a program. The ‘Z’ field denotes the value of ‘rG’ at the beginning of the program. The following 256 - Z big-endian 64-bit words are loaded into global registers ‘$G’ … ‘$255’.

lop_stab

0x980b0000. The next-to-last lopcode in a program. Must follow immediately after the lop_post lopcode and its data. After this lopcode follows all symbols in a compressed format (see Symbol table format).

lop_end

0x980cYYZZ. The last lopcode in a program. It must follow the lop_stab lopcode and its data. The ‘YZ’ field contains the number of 32-bit words of symbol table information after the preceding lop_stab lopcode.

Note that the lopcode "fixups"; lop_fixr, lop_fixrx and lop_fixo are not generated by BFD, but are handled. They are generated by mmixal.

This trivial one-label, one-instruction file:

 :Main TRAP 1,2,3

can be represented this way in mmo:

 0x98090101 - lop_pre, one 32-bit word with timestamp.
 <timestamp>
 0x98010002 - lop_loc, text segment, using a 64-bit address.
              Note that mmixal does not emit this for the file above.
 0x00000000 - Address, high 32 bits.
 0x00000000 - Address, low 32 bits.
 0x98060002 - lop_file, 2 32-bit words for file-name.
 0x74657374 - "test"
 0x2e730000 - ".s\0\0"
 0x98070001 - lop_line, line 1.
 0x00010203 - TRAP 1,2,3
 0x980a00ff - lop_post, setting $255 to 0.
 0x00000000
 0x00000000
 0x980b0000 - lop_stab for ":Main" = 0, serial 1.
 0x203a4040   See Symbol table format.
 0x10404020
 0x4d206120
 0x69016e00
 0x81000000
 0x980c0005 - lop_end; symbol table contained five 32-bit words.

3.5.2 Symbol table format

From mmixal.w (or really, the generated mmixal.tex) in the MMIXware package which also contains the mmix simulator: “Symbols are stored and retrieved by means of a ‘ternary search trie’, following ideas of Bentley and Sedgewick. (See ACM–SIAM Symp. on Discrete Algorithms ‘8’ (1997), 360–369; R.Sedgewick, ‘Algorithms in C’ (Reading, Mass. Addison–Wesley, 1998), ‘15.4’.) Each trie node stores a character, and there are branches to subtries for the cases where a given character is less than, equal to, or greater than the character in the trie. There also is a pointer to a symbol table entry if a symbol ends at the current node.”

So it’s a tree encoded as a stream of bytes. The stream of bytes acts on a single virtual global symbol, adding and removing characters and signalling complete symbol points. Here, we read the stream and create symbols at the completion points.

First, there’s a control byte m. If any of the listed bits in m is nonzero, we execute what stands at the right, in the listed order:

 (MMO3_LEFT)
 0x40 - Traverse left trie.
        (Read a new command byte and recurse.)

 (MMO3_SYMBITS)
 0x2f - Read the next byte as a character and store it in the
        current character position; increment character position.
        Test the bits of m:

        (MMO3_WCHAR)
        0x80 - The character is 16-bit (so read another byte,
               merge into current character.

        (MMO3_TYPEBITS)
        0xf  - We have a complete symbol; parse the type, value
               and serial number and do what should be done
               with a symbol.  The type and length information
               is in j = (m & 0xf).

               (MMO3_REGQUAL_BITS)
               j == 0xf: A register variable.  The following
                         byte tells which register.
               j <= 8:   An absolute symbol.  Read j bytes as the
                         big-endian number the symbol equals.
                         A j = 2 with two zero bytes denotes an
                         unknown symbol.
               j > 8:    As with j <= 8, but add (0x20 << 56)
                         to the value in the following j - 8
                         bytes.

               Then comes the serial number, as a variant of
               uleb128, but better named ubeb128:
               Read bytes and shift the previous value left 7
               (multiply by 128).  Add in the new byte, repeat
               until a byte has bit 7 set.  The serial number
               is the computed value minus 128.

        (MMO3_MIDDLE)
        0x20 - Traverse middle trie.  (Read a new command byte
               and recurse.)  Decrement character position.

 (MMO3_RIGHT)
 0x10 - Traverse right trie.  (Read a new command byte and
        recurse.)

Let’s look again at the lop_stab for the trivial file (see File layout).

 0x980b0000 - lop_stab for ":Main" = 0, serial 1.
 0x203a4040
 0x10404020
 0x4d206120
 0x69016e00
 0x81000000

This forms the trivial trie (note that the path between “:” and “M” is redundant):

 203a     ":"
 40       /
 40      /
 10      \
 40      /
 40     /
 204d  "M"
 2061  "a"
 2069  "i"
 016e  "n" is the last character in a full symbol, and
       with a value represented in one byte.
 00    The value is 0.
 81    The serial number is 1.

3.5.3 mmo section mapping

The implementation in BFD uses special data type 80 (decimal) to encapsulate and describe named sections, containing e.g. debug information. If needed, any datum in the encapsulation will be quoted using lop_quote. First comes a 32-bit word holding the number of 32-bit words containing the zero-terminated zero-padded segment name. After the name there’s a 32-bit word holding flags describing the section type. Then comes a 64-bit big-endian word with the section length (in bytes), then another with the section start address. Depending on the type of section, the contents might follow, zero-padded to 32-bit boundary. For a loadable section (such as data or code), the contents might follow at some later point, not necessarily immediately, as a lop_loc with the same start address as in the section description, followed by the contents. This in effect forms a descriptor that must be emitted before the actual contents. Sections described this way must not overlap.

For areas that don’t have such descriptors, synthetic sections are formed by BFD. Consecutive contents in the two memory areas ‘0x0000…00’ to ‘0x01ff…ff’ and ‘0x2000…00’ to ‘0x20ff…ff’ are entered in sections named .text and .data respectively. If an area is not otherwise described, but would together with a neighboring lower area be less than ‘0x40000000’ bytes long, it is joined with the lower area and the gap is zero-filled. For other cases, a new section is formed, named .MMIX.sec.n. Here, n is a number, a running count through the mmo file, starting at 0.

A loadable section specified as:

 .section secname,"ax"
 TETRA 1,2,3,4,-1,-2009
 BYTE 80

and linked to address ‘0x4’, is represented by the sequence:

 0x98080050 - lop_spec 80
 0x00000002 - two 32-bit words for the section name
 0x7365636e - "secn"
 0x616d6500 - "ame\0"
 0x00000033 - flags CODE, READONLY, LOAD, ALLOC
 0x00000000 - high 32 bits of section length
 0x0000001c - section length is 28 bytes; 6 * 4 + 1 + alignment to 32 bits
 0x00000000 - high 32 bits of section address
 0x00000004 - section address is 4
 0x98010002 - 64 bits with address of following data
 0x00000000 - high 32 bits of address
 0x00000004 - low 32 bits: data starts at address 4
 0x00000001 - 1
 0x00000002 - 2
 0x00000003 - 3
 0x00000004 - 4
 0xffffffff - -1
 0xfffff827 - -2009
 0x50000000 - 80 as a byte, padded with zeros.

Note that the lop_spec wrapping does not include the section contents. Compare this to a non-loaded section specified as:

 .section thirdsec
 TETRA 200001,100002
 BYTE 38,40

This, when linked to address ‘0x200000000000001c’, is represented by:

 0x98080050 - lop_spec 80
 0x00000002 - two 32-bit words for the section name
 0x7365636e - "thir"
 0x616d6500 - "dsec"
 0x00000010 - flag READONLY
 0x00000000 - high 32 bits of section length
 0x0000000c - section length is 12 bytes; 2 * 4 + 2 + alignment to 32 bits
 0x20000000 - high 32 bits of address
 0x0000001c - low 32 bits of address 0x200000000000001c
 0x00030d41 - 200001
 0x000186a2 - 100002
 0x26280000 - 38, 40 as bytes, padded with zeros

For the latter example, the section contents must not be loaded in memory, and is therefore specified as part of the special data. The address is usually unimportant but might provide information for e.g. the DWARF 2 debugging format.

Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
  1. PREAMBLE

    The purpose of this License is to make a manual, textbook, or other functional and useful document free in the sense of freedom: to assure everyone the effective freedom to copy and redistribute it, with or without modifying it, either commercially or noncommercially. Secondarily, this License preserves for the author and publisher a way to get credit for their work, while not being considered responsible for modifications made by others.

    This License is a kind of “copyleft”, which means that derivative works of the document must themselves be free in the same sense. It complements the GNU General Public License, which is a copyleft license designed for free software.

    We have designed this License in order to use it for manuals for free software, because free software needs free documentation: a free program should come with manuals providing the same freedoms that the software does. But this License is not limited to software manuals; it can be used for any textual work, regardless of subject matter or whether it is published as a printed book. We recommend this License principally for works whose purpose is instruction or reference.

  2. APPLICABILITY AND DEFINITIONS

    This License applies to any manual or other work, in any medium, that contains a notice placed by the copyright holder saying it can be distributed under the terms of this License. Such a notice grants a world-wide, royalty-free license, unlimited in duration, to use that work under the conditions stated herein. The “Document”, below, refers to any such manual or work. Any member of the public is a licensee, and is addressed as “you”. You accept the license if you copy, modify or distribute the work in a way requiring permission under copyright law.

    A “Modified Version” of the Document means any work containing the Document or a portion of it, either copied verbatim, or with modifications and/or translated into another language.

    A “Secondary Section” is a named appendix or a front-matter section of the Document that deals exclusively with the relationship of the publishers or authors of the Document to the Document’s overall subject (or to related matters) and contains nothing that could fall directly within that overall subject. (Thus, if the Document is in part a textbook of mathematics, a Secondary Section may not explain any mathematics.) The relationship could be a matter of historical connection with the subject or with related matters, or of legal, commercial, philosophical, ethical or political position regarding them.

    The “Invariant Sections” are certain Secondary Sections whose titles are designated, as being those of Invariant Sections, in the notice that says that the Document is released under this License. If a section does not fit the above definition of Secondary then it is not allowed to be designated as Invariant. The Document may contain zero Invariant Sections. If the Document does not identify any Invariant Sections then there are none.

    The “Cover Texts” are certain short passages of text that are listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says that the Document is released under this License. A Front-Cover Text may be at most 5 words, and a Back-Cover Text may be at most 25 words.

    A “Transparent” copy of the Document means a machine-readable copy, represented in a format whose specification is available to the general public, that is suitable for revising the document straightforwardly with generic text editors or (for images composed of pixels) generic paint programs or (for drawings) some widely available drawing editor, and that is suitable for input to text formatters or for automatic translation to a variety of formats suitable for input to text formatters. A copy made in an otherwise Transparent file format whose markup, or absence of markup, has been arranged to thwart or discourage subsequent modification by readers is not Transparent. An image format is not Transparent if used for any substantial amount of text. A copy that is not “Transparent” is called “Opaque”.

    Examples of suitable formats for Transparent copies include plain ASCII without markup, Texinfo input format, LaTeX input format, SGML or XML using a publicly available DTD, and standard-conforming simple HTML, PostScript or PDF designed for human modification. Examples of transparent image formats include PNG, XCF and JPG. Opaque formats include proprietary formats that can be read and edited only by proprietary word processors, SGML or XML for which the DTD and/or processing tools are not generally available, and the machine-generated HTML, PostScript or PDF produced by some word processors for output purposes only.

    The “Title Page” means, for a printed book, the title page itself, plus such following pages as are needed to hold, legibly, the material this License requires to appear in the title page. For works in formats which do not have any title page as such, “Title Page” means the text near the most prominent appearance of the work’s title, preceding the beginning of the body of the text.

    The “publisher” means any person or entity that distributes copies of the Document to the public.

    A section “Entitled XYZ” means a named subunit of the Document whose title either is precisely XYZ or contains XYZ in parentheses following text that translates XYZ in another language. (Here XYZ stands for a specific section name mentioned below, such as “Acknowledgements”, “Dedications”, “Endorsements”, or “History”.) To “Preserve the Title” of such a section when you modify the Document means that it remains a section “Entitled XYZ” according to this definition.

    The Document may include Warranty Disclaimers next to the notice which states that this License applies to the Document. These Warranty Disclaimers are considered to be included by reference in this License, but only as regards disclaiming warranties: any other implication that these Warranty Disclaimers may have is void and has no effect on the meaning of this License.

  3. VERBATIM COPYING

    You may copy and distribute the Document in any medium, either commercially or noncommercially, provided that this License, the copyright notices, and the license notice saying this License applies to the Document are reproduced in all copies, and that you add no other conditions whatsoever to those of this License. You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute. However, you may accept compensation in exchange for copies. If you distribute a large enough number of copies you must also follow the conditions in section 3.

    You may also lend copies, under the same conditions stated above, and you may publicly display copies.

  4. COPYING IN QUANTITY

    If you publish printed copies (or copies in media that commonly have printed covers) of the Document, numbering more than 100, and the Document’s license notice requires Cover Texts, you must enclose the copies in covers that carry, clearly and legibly, all these Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the back cover. Both covers must also clearly and legibly identify you as the publisher of these copies. The front cover must present the full title with all words of the title equally prominent and visible. You may add other material on the covers in addition. Copying with changes limited to the covers, as long as they preserve the title of the Document and satisfy these conditions, can be treated as verbatim copying in other respects.

    If the required texts for either cover are too voluminous to fit legibly, you should put the first ones listed (as many as fit reasonably) on the actual cover, and continue the rest onto adjacent pages.

    If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a machine-readable Transparent copy along with each Opaque copy, or state in or with each Opaque copy a computer-network location from which the general network-using public has access to download using public-standard network protocols a complete Transparent copy of the Document, free of added material. If you use the latter option, you must take reasonably prudent steps, when you begin distribution of Opaque copies in quantity, to ensure that this Transparent copy will remain thus accessible at the stated location until at least one year after the last time you distribute an Opaque copy (directly or through your agents or retailers) of that edition to the public.

    It is requested, but not required, that you contact the authors of the Document well before redistributing any large number of copies, to give them a chance to provide you with an updated version of the Document.

  5. MODIFICATIONS

    You may copy and distribute a Modified Version of the Document under the conditions of sections 2 and 3 above, provided that you release the Modified Version under precisely this License, with the Modified Version filling the role of the Document, thus licensing distribution and modification of the Modified Version to whoever possesses a copy of it. In addition, you must do these things in the Modified Version:

    1. Use in the Title Page (and on the covers, if any) a title distinct from that of the Document, and from those of previous versions (which should, if there were any, be listed in the History section of the Document). You may use the same title as a previous version if the original publisher of that version gives permission.
    2. List on the Title Page, as authors, one or more persons or entities responsible for authorship of the modifications in the Modified Version, together with at least five of the principal authors of the Document (all of its principal authors, if it has fewer than five), unless they release you from this requirement.
    3. State on the Title page the name of the publisher of the Modified Version, as the publisher.
    4. Preserve all the copyright notices of the Document.
    5. Add an appropriate copyright notice for your modifications adjacent to the other copyright notices.
    6. Include, immediately after the copyright notices, a license notice giving the public permission to use the Modified Version under the terms of this License, in the form shown in the Addendum below.
    7. Preserve in that license notice the full lists of Invariant Sections and required Cover Texts given in the Document’s license notice.
    8. Include an unaltered copy of this License.
    9. Preserve the section Entitled “History”, Preserve its Title, and add to it an item stating at least the title, year, new authors, and publisher of the Modified Version as given on the Title Page. If there is no section Entitled “History” in the Document, create one stating the title, year, authors, and publisher of the Document as given on its Title Page, then add an item describing the Modified Version as stated in the previous sentence.
    10. Preserve the network location, if any, given in the Document for public access to a Transparent copy of the Document, and likewise the network locations given in the Document for previous versions it was based on. These may be placed in the “History” section. You may omit a network location for a work that was published at least four years before the Document itself, or if the original publisher of the version it refers to gives permission.
    11. For any section Entitled “Acknowledgements” or “Dedications”, Preserve the Title of the section, and preserve in the section all the substance and tone of each of the contributor acknowledgements and/or dedications given therein.
    12. Preserve all the Invariant Sections of the Document, unaltered in their text and in their titles. Section numbers or the equivalent are not considered part of the section titles.
    13. Delete any section Entitled “Endorsements”. Such a section may not be included in the Modified Version.
    14. Do not retitle any existing section to be Entitled “Endorsements” or to conflict in title with any Invariant Section.
    15. Preserve any Warranty Disclaimers.

    If the Modified Version includes new front-matter sections or appendices that qualify as Secondary Sections and contain no material copied from the Document, you may at your option designate some or all of these sections as invariant. To do this, add their titles to the list of Invariant Sections in the Modified Version’s license notice. These titles must be distinct from any other section titles.

    You may add a section Entitled “Endorsements”, provided it contains nothing but endorsements of your Modified Version by various parties—for example, statements of peer review or that the text has been approved by an organization as the authoritative definition of a standard.

    You may add a passage of up to five words as a Front-Cover Text, and a passage of up to 25 words as a Back-Cover Text, to the end of the list of Cover Texts in the Modified Version. Only one passage of Front-Cover Text and one of Back-Cover Text may be added by (or through arrangements made by) any one entity. If the Document already includes a cover text for the same cover, previously added by you or by arrangement made by the same entity you are acting on behalf of, you may not add another; but you may replace the old one, on explicit permission from the previous publisher that added the old one.

    The author(s) and publisher(s) of the Document do not by this License give permission to use their names for publicity for or to assert or imply endorsement of any Modified Version.

  6. COMBINING DOCUMENTS

    You may combine the Document with other documents released under this License, under the terms defined in section 4 above for modified versions, provided that you include in the combination all of the Invariant Sections of all of the original documents, unmodified, and list them all as Invariant Sections of your combined work in its license notice, and that you preserve all their Warranty Disclaimers.

    The combined work need only contain one copy of this License, and multiple identical Invariant Sections may be replaced with a single copy. If there are multiple Invariant Sections with the same name but different contents, make the title of each such section unique by adding at the end of it, in parentheses, the name of the original author or publisher of that section if known, or else a unique number. Make the same adjustment to the section titles in the list of Invariant Sections in the license notice of the combined work.

    In the combination, you must combine any sections Entitled “History” in the various original documents, forming one section Entitled “History”; likewise combine any sections Entitled “Acknowledgements”, and any sections Entitled “Dedications”. You must delete all sections Entitled “Endorsements.”

  7. COLLECTIONS OF DOCUMENTS

    You may make a collection consisting of the Document and other documents released under this License, and replace the individual copies of this License in the various documents with a single copy that is included in the collection, provided that you follow the rules of this License for verbatim copying of each of the documents in all other respects.

    You may extract a single document from such a collection, and distribute it individually under this License, provided you insert a copy of this License into the extracted document, and follow this License in all other respects regarding verbatim copying of that document.

  8. AGGREGATION WITH INDEPENDENT WORKS

    A compilation of the Document or its derivatives with other separate and independent documents or works, in or on a volume of a storage or distribution medium, is called an “aggregate” if the copyright resulting from the compilation is not used to limit the legal rights of the compilation’s users beyond what the individual works permit. When the Document is included in an aggregate, this License does not apply to the other works in the aggregate which are not themselves derivative works of the Document.

    If the Cover Text requirement of section 3 is applicable to these copies of the Document, then if the Document is less than one half of the entire aggregate, the Document’s Cover Texts may be placed on covers that bracket the Document within the aggregate, or the electronic equivalent of covers if the Document is in electronic form. Otherwise they must appear on printed covers that bracket the whole aggregate.

  9. TRANSLATION

    Translation is considered a kind of modification, so you may distribute translations of the Document under the terms of section 4. Replacing Invariant Sections with translations requires special permission from their copyright holders, but you may include translations of some or all Invariant Sections in addition to the original versions of these Invariant Sections. You may include a translation of this License, and all the license notices in the Document, and any Warranty Disclaimers, provided that you also include the original English version of this License and the original versions of those notices and disclaimers. In case of a disagreement between the translation and the original version of this License or a notice or disclaimer, the original version will prevail.

    If a section in the Document is Entitled “Acknowledgements”, “Dedications”, or “History”, the requirement (section 4) to Preserve its Title (section 1) will typically require changing the actual title.

  10. TERMINATION

    You may not copy, modify, sublicense, or distribute the Document except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, or distribute it is void, and will automatically terminate your rights under this License.

    However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.

    Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.

    Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, receipt of a copy of some or all of the same material does not give you any rights to use it.

  11. FUTURE REVISIONS OF THIS LICENSE

    The Free Software Foundation may publish new, revised versions of the GNU Free Documentation License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. See http://www.gnu.org/copyleft/.

    Each version of the License is given a distinguishing version number. If the Document specifies that a particular numbered version of this License “or any later version” applies to it, you have the option of following the terms and conditions either of that specified version or of any later version that has been published (not as a draft) by the Free Software Foundation. If the Document does not specify a version number of this License, you may choose any version ever published (not as a draft) by the Free Software Foundation. If the Document specifies that a proxy can decide which future versions of this License can be used, that proxy’s public statement of acceptance of a version permanently authorizes you to choose that version for the Document.

  12. RELICENSING

    “Massive Multiauthor Collaboration Site” (or “MMC Site”) means any World Wide Web server that publishes copyrightable works and also provides prominent facilities for anybody to edit those works. A public wiki that anybody can edit is an example of such a server. A “Massive Multiauthor Collaboration” (or “MMC”) contained in the site means any set of copyrightable works thus published on the MMC site.

    “CC-BY-SA” means the Creative Commons Attribution-Share Alike 3.0 license published by Creative Commons Corporation, a not-for-profit corporation with a principal place of business in San Francisco, California, as well as future copyleft versions of that license published by that same organization.

    “Incorporate” means to publish or republish a Document, in whole or in part, as part of another Document.

    An MMC is “eligible for relicensing” if it is licensed under this License, and if all works that were first published under this License somewhere other than this MMC, and subsequently incorporated in whole or in part into the MMC, (1) had no cover texts or invariant sections, and (2) were thus incorporated prior to November 1, 2008.

    The operator of an MMC Site may republish an MMC contained in the site under CC-BY-SA on the same site at any time before August 1, 2009, provided the MMC is eligible for relicensing.

ADDENDUM: How to use this License for your documents

To use this License in a document you have written, include a copy of the License in the document and put the following copyright and license notices just after the title page:

  Copyright (C)  year  your name.
  Permission is granted to copy, distribute and/or modify this document
  under the terms of the GNU Free Documentation License, Version 1.3
  or any later version published by the Free Software Foundation;
  with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
  Texts.  A copy of the license is included in the section entitled ``GNU
  Free Documentation License''.

If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, replace the “with…Texts.” line with this:

    with the Invariant Sections being list their titles, with
    the Front-Cover Texts being list, and with the Back-Cover Texts
    being list.

If you have Invariant Sections without Cover Texts, or some other combination of the three, merge those two alternatives to suit the situation.

If your document contains nontrivial examples of program code, we recommend releasing these examples in parallel under your choice of free software license, such as the GNU General Public License, to permit their use in free software.
