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 BFD Front End


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.

Here is the structure that defines the type bfd. It contains the major data about the file and pointers to the rest of the data.

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.

The BFD error is thread-local.

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

Function: bfd_error_type bfd_get_error (void);

Return the current BFD error condition.

2.2.1.2 bfd_set_error

Function: void bfd_set_error (bfd_error_type error_tag);

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

Function: void bfd_set_input_error (bfd *input, bfd_error_type error_tag);

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

Function: const char *bfd_errmsg (bfd_error_type error_tag);

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

Function: void bfd_perror (const char *message);

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.

2.2.1.6 _bfd_clear_error_data

Function: void _bfd_clear_error_data (void);

Free any data associated with the BFD error.

2.2.1.7 bfd_asprintf

Function: char *bfd_asprintf (const char *fmt, ...);

Primarily for error reporting, this function is like libiberty’s xasprintf except that it can return NULL on no memory and the returned string should not be freed. Uses a thread-local malloc’d buffer managed by libbfd, _bfd_error_buf. Be aware that a call to this function frees the result of any previous call. bfd_errmsg (bfd_error_on_input) also calls this function.

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

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

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

Function: bfd_error_handler_type bfd_set_error_handler (bfd_error_handler_type);

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

2.2.2.3 _bfd_set_error_handler_caching

Function: bfd_error_handler_type _bfd_set_error_handler_caching (bfd *);

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

Function: void bfd_set_error_program_name (const char *);

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

Function: const char *_bfd_get_error_program_name (void);

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

Function: bfd_assert_handler_type bfd_set_assert_handler (bfd_assert_handler_type);

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


2.2.3.2 bfd_init

Function: unsigned int bfd_init (void);

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))


2.3 Threading

BFD has limited support for thread-safety. Most BFD globals are protected by locks, while the error-related globals are thread-local. A given BFD cannot safely be used from two threads at the same time; it is up to the application to do any needed locking. However, it is ok for different threads to work on different BFD objects at the same time.

2.3.1 Thread functions.

typedef bool (*bfd_lock_unlock_fn_type) (void *);

2.3.1.1 bfd_thread_init

Function: bool bfd_thread_init (bfd_lock_unlock_fn_type lock, bfd_lock_unlock_fn_type unlock, void *data);

Initialize BFD threading. The functions passed in will be used to lock and unlock global data structures. This may only be called a single time in a given process. Returns true on success and false on error. DATA is passed verbatim to the lock and unlock functions. The lock and unlock functions should return true on success, or set the BFD error and return false on failure.

2.3.1.2 bfd_thread_cleanup

Function: void bfd_thread_cleanup (void);

Clean up any thread-local state. This should be called by a thread that uses any BFD functions, before the thread exits. It is fine to call this multiple times, or to call it and then later call BFD functions on the same thread again.

2.3.1.3 bfd_lock

Function: bool bfd_lock (void);

Acquire the global BFD lock, if needed. Returns true on success, false on error.

2.3.1.4 bfd_unlock

Function: bool bfd_unlock (void);

Release the global BFD lock, if needed. Returns true on success, false on error.


2.4 Miscellaneous

2.4.1 Miscellaneous functions

2.4.1.1 bfd_get_reloc_upper_bound

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

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.

2.4.1.2 bfd_canonicalize_reloc

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

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.

2.4.1.3 bfd_set_reloc

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

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))

2.4.1.4 bfd_set_file_flags

Function: bool bfd_set_file_flags (bfd *abfd, flagword flags);

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.

2.4.1.5 bfd_get_arch_size

Function: int bfd_get_arch_size (bfd *abfd);

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

2.4.1.6 bfd_get_sign_extend_vma

Function: int bfd_get_sign_extend_vma (bfd *abfd);

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 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.

2.4.1.7 bfd_set_start_address

Function: bool bfd_set_start_address (bfd *abfd, bfd_vma vma);

Make vma the entry point of output BFD abfd.

Returns TRUE on success, FALSE otherwise.

2.4.1.8 bfd_get_gp_size

Function: unsigned int bfd_get_gp_size (bfd *abfd);

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.

2.4.1.9 bfd_set_gp_size

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

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.

2.4.1.10 bfd_set_gp_value

Function: void bfd_set_gp_value (bfd *abfd, bfd_vma v);

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

2.4.1.11 bfd_scan_vma

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

Convert, like strtoul or stdtoulldepending on the size of a bfd_vma, a numerical expression string into a bfd_vma integer, and return that integer.

2.4.1.12 bfd_copy_private_header_data

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

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))

2.4.1.13 bfd_copy_private_bfd_data

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

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))

2.4.1.14 bfd_set_private_flags

Function: bool bfd_set_private_flags (bfd *abfd, flagword flags);

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.
#define bfd_set_private_flags(abfd, flags) \
       BFD_SEND (abfd, _bfd_set_private_flags, (abfd, flags))

extern const struct bfd_iovec _bfd_memory_iovec;

2.4.1.24 bfd_read

Function: bfd_size_type bfd_read (void *, bfd_size_type, bfd *) ATTRIBUTE_WARN_UNUSED_RESULT;

Attempt to read SIZE bytes from ABFD’s iostream to PTR. Return the amount read.

2.4.1.25 bfd_write

Function: bfd_size_type bfd_write (const void *, bfd_size_type, bfd *) ATTRIBUTE_WARN_UNUSED_RESULT;

Attempt to write SIZE bytes to ABFD’s iostream from PTR. Return the amount written.

2.4.1.26 bfd_tell

Function: file_ptr bfd_tell (bfd *) ATTRIBUTE_WARN_UNUSED_RESULT;

Return ABFD’s iostream file position.

2.4.1.27 bfd_flush

Function: int bfd_flush (bfd *);

Flush ABFD’s iostream pending IO.

2.4.1.28 bfd_stat

Function: int bfd_stat (bfd *, struct stat *) ATTRIBUTE_WARN_UNUSED_RESULT;

Call fstat on ABFD’s iostream. Return 0 on success, and a negative value on failure.

2.4.1.29 bfd_seek

Function: int bfd_seek (bfd *, file_ptr, int) ATTRIBUTE_WARN_UNUSED_RESULT;

Call fseek on ABFD’s iostream. Return 0 on success, and a negative value on failure.

2.4.1.30 bfd_get_mtime

Function: long bfd_get_mtime (bfd *abfd);

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

2.4.1.31 bfd_get_size

Function: ufile_ptr bfd_get_size (bfd *abfd);

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.

2.4.1.32 bfd_get_file_size

Function: ufile_ptr bfd_get_file_size (bfd *abfd);

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

2.4.1.33 bfd_mmap

Function: 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) ATTRIBUTE_WARN_UNUSED_RESULT;

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.

2.4.1.34 bfd_get_current_time

Function: time_t bfd_get_current_time (time_t now);

Returns the current time.

If the environment variable SOURCE_DATE_EPOCH is defined then this is parsed and its value is returned. Otherwise if the paramter NOW is non-zero, then that is returned. Otherwise the result of the system call "time(NULL)" is returned.


2.5 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.


2.6 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  --------|

2.6.4 typedef asection

Here is the section structure:

typedef struct bfd_section
{
  /* The name of the section; the name isn't a copy, the pointer is
     the same as that passed to bfd_make_section.  */
  const char *name;

  /* The next section in the list belonging to the BFD, or NULL.  */

2.6.5 Section prototypes

These are the functions exported by the section handling part of BFD.

2.6.5.1 bfd_section_list_clear

Function: void bfd_section_list_clear (bfd *);

Clears the section list, and also resets the section count and hash table entries.

2.6.5.2 bfd_get_section_by_name

Function: asection *bfd_get_section_by_name (bfd *abfd, const char *name);

Return the most recently created section attached to abfd named name. Return NULL if no such section exists.

2.6.5.3 bfd_get_next_section_by_name

Function: asection *bfd_get_next_section_by_name (bfd *ibfd, asection *sec);

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

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

Return the linker created section attached to abfd named name. Return NULL if no such section exists.

2.6.5.5 bfd_get_section_by_name_if

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Function: bool bfd_set_section_flags (asection *sec, flagword flags);

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

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

Rename section sec to newname.

2.6.5.14 bfd_map_over_sections

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

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

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

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

Function: bool bfd_set_section_size (asection *sec, bfd_size_type val);

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

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

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

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

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

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

Read all data from section in BFD abfd into a buffer, *buf, malloc’d by this function. Return true on success, false on failure in which case *buf will be NULL.

2.6.5.20 bfd_copy_private_section_data

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

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

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

Returns TRUE if sec is a member of a group.

2.6.5.22 bfd_generic_group_name

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

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

2.6.5.23 bfd_generic_discard_group

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

Remove all members of group from the output.

2.6.5.24 _bfd_section_size_insane

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

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

     This field is *almost* redundant, since you can use section->owner
     instead, except that some symbols point to the global sections

2.7.5 Symbol handling functions

2.7.5.1 bfd_get_symtab_upper_bound

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

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

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

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

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

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

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

2.7.5.8 bfd_make_empty_symbol

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

2.7.5.14 bfd_copy_private_symbol_data

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

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

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

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

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

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

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

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

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

Function: bool bfd_check_format (bfd *abfd, bfd_format format);

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

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

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

Function: bool bfd_set_format (bfd *abfd, bfd_format format);

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

Function: const char *bfd_format_string (bfd_format format);

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:

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;

};

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

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.

  • 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;

  /* Whether bfd_install_relocation should just install the addend,
     or should follow the practice of some older object formats and
     install a value including the symbol.  */
  unsigned int install_addend: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

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

#define HOWTO_INSTALL_ADDEND 0
#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, HOWTO_INSTALL_ADDEND,         \
    src_mask, dst_mask, func, name }

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

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

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

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

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

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

2.10.1.7 bfd_perform_relocation

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

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. The error_message argument is set to an error message if this return bfd_reloc_dangerous.

2.10.1.8 bfd_install_relocation

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

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_real_type

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_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.

Absolute 8-bit relocation, but used to form an address like 0xFFnn.

: 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.

SPARC ELF relocations. There is probably some overlap with other relocation types already defined.

I think these are specific to SPARC a.out (e.g., Sun 4).

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.

The MIPS16 jump instruction.

: BFD_RELOC_MIPS16_GPREL

MIPS16 GP relative reloc.

: BFD_RELOC_HI16

High 16 bits of 32-bit value; simple reloc.

: BFD_RELOC_HI16_S

High 16 bits of 32-bit value but the low 16 bits will be sign extended and added to form the final result. If the low 16 bits form a negative number, we need to add one to the high value to compensate for the borrow when the low bits are added.

: BFD_RELOC_LO16

Low 16 bits.

: BFD_RELOC_HI16_PCREL

High 16 bits of 32-bit pc-relative value.

MIPS16 high 16 bits of 32-bit value.

: BFD_RELOC_MIPS16_HI16_S

: 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.

typedef enum bfd_reloc_code_real bfd_reloc_code_real_type;

2.10.2.2 bfd_reloc_type_lookup

Function: reloc_howto_type *bfd_reloc_type_lookup (bfd *abfd, bfd_reloc_code_real_type code); reloc_howto_type *bfd_reloc_name_lookup (bfd *abfd, const char *reloc_name);

Return a pointer to a howto structure which, when invoked, will perform the relocation code on data from the architecture noted.

2.10.2.3 bfd_default_reloc_type_lookup

Function: reloc_howto_type *bfd_default_reloc_type_lookup (bfd *abfd, bfd_reloc_code_real_type code);

Provides a default relocation lookup routine for any architecture.

2.10.2.4 bfd_get_reloc_code_name

Function: const char *bfd_get_reloc_code_name (bfd_reloc_code_real_type code);

Provides a printable name for the supplied relocation code. Useful mainly for printing error messages.

2.10.2.5 bfd_generic_relax_section

Function: bool bfd_generic_relax_section (bfd *abfd, asection *section, struct bfd_link_info *, bool *);

Provides default handling for relaxing for back ends which don’t do relaxing.

2.10.2.6 bfd_generic_gc_sections

Function: bool bfd_generic_gc_sections (bfd *, struct bfd_link_info *);

Provides default handling for relaxing for back ends which don’t do section gc – i.e., does nothing.

2.10.2.7 bfd_generic_lookup_section_flags

Function: bool bfd_generic_lookup_section_flags (struct bfd_link_info *, struct flag_info *, asection *);

Provides default handling for section flags lookup – i.e., does nothing. Returns FALSE if the section should be omitted, otherwise TRUE.

2.10.2.8 bfd_generic_merge_sections

Function: bool bfd_generic_merge_sections (bfd *, struct bfd_link_info *);

Provides default handling for SEC_MERGE section merging for back ends which don’t have SEC_MERGE support – i.e., does nothing.

2.10.2.9 bfd_generic_get_relocated_section_contents

Function: bfd_byte *bfd_generic_get_relocated_section_contents (bfd *abfd, struct bfd_link_info *link_info, struct bfd_link_order *link_order, bfd_byte *data, bool relocatable, asymbol **symbols);

Provides default handling of relocation effort for back ends which can’t be bothered to do it efficiently.

2.10.2.10 _bfd_generic_set_reloc

Function: void _bfd_generic_set_reloc (bfd *abfd, sec_ptr section, arelent **relptr, unsigned int count);

Installs a new set of internal relocations in SECTION.

2.10.2.11 _bfd_unrecognized_reloc

Function: bool _bfd_unrecognized_reloc (bfd * abfd, sec_ptr section, unsigned int r_type);

Reports an unrecognized reloc. Written as a function in order to reduce code duplication. Returns FALSE so that it can be called from a return statement.
