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).
* The front end of BFD provides the interface to the user. It manages
memory and various canonical data structures. The front end also
decides which back end to use and when to call back end routines.
* The back ends provide BFD its view of the real world. Each back
end provides a set of calls which the BFD front end can use to
maintain its canonical form. The back ends also may keep around
information for their own use, for greater efficiency.

File: bfd.info, Node: History, Next: How It Works, Prev: Overview, Up: Overview
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').

File: bfd.info, Node: How It Works, Next: What BFD Version 2 Can Do, Prev: History, Up: Overview
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:
* a header,
* a number of sections containing raw data (*note Sections::),
* a set of relocations (*note Relocations::), and
* some symbol information (*note Symbols::).
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.

File: bfd.info, Node: BFD information loss, Next: Canonical format, Up: What BFD Version 2 Can Do
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.

File: bfd.info, Node: Canonical format, Prev: BFD information loss, Up: What BFD Version 2 Can Do
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, IEEE, 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 (COFF, IEEE and Oasys).

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_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_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. If ERROR_TAG is
bfd_error_on_input, then this function takes two more parameters, the
input bfd where the error occurred, and the bfd_error_type error.
2.2.1.3 `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'.
2.2.1.4 `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 printf.
typedef void (*bfd_error_handler_type) (const char *, ...);
2.2.2.1 `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.
2.2.2.2 `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.
2.2.2.3 `bfd_get_error_handler'
...............................
*Synopsis*
bfd_error_handler_type bfd_get_error_handler (void);
*Description*
Return the BFD error handler function.
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.
2.2.3.2 `bfd_get_assert_handler'
................................
*Synopsis*
bfd_assert_handler_type bfd_get_assert_handler (void);
*Description*
Return the BFD assert handler 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.
2.3.1.4 `bfd_set_file_flags'
............................
*Synopsis*
bfd_boolean 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 architecture address size, in bits, as determined by the
object file's format. For ELF, this information is included in the
header.
*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*
bfd_boolean 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_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.
2.3.1.11 `bfd_copy_private_header_data'
.......................................
*Synopsis*
bfd_boolean 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.

2.3.1.16 `bfd_alt_mach_code'
............................
*Synopsis*
bfd_boolean bfd_alt_mach_code (bfd *abfd, int alternative);
*Description*
When more than one machine code number is available for the same
machine type, this function can be used to switch between the preferred
one (alternative == 0) and any others. Currently, only ELF supports
this feature, with up to two alternate machine codes.
struct bfd_preserve
{

2.3.1.17 `bfd_preserve_save'
............................
*Synopsis*
bfd_boolean bfd_preserve_save (bfd *, struct bfd_preserve *);
*Description*
When testing an object for compatibility with a particular target
back-end, the back-end object_p function needs to set up certain fields
in the bfd on successfully recognizing the object. This typically
happens in a piecemeal fashion, with failures possible at many points.
On failure, the bfd is supposed to be restored to its initial state,
which is virtually impossible. However, restoring a subset of the bfd
state works in practice. This function stores the subset and
reinitializes the bfd.
2.3.1.18 `bfd_preserve_restore'
...............................
*Synopsis*
void bfd_preserve_restore (bfd *, struct bfd_preserve *);
*Description*
This function restores bfd state saved by bfd_preserve_save. If MARKER
is non-NULL in struct bfd_preserve then that block and all subsequently
bfd_alloc'd memory is freed.
2.3.1.19 `bfd_preserve_finish'
..............................
*Synopsis*
void bfd_preserve_finish (bfd *, struct bfd_preserve *);
*Description*
This function should be called when the bfd state saved by
bfd_preserve_save is no longer needed. ie. when the back-end object_p
function returns with success.
2.3.1.20 `bfd_emul_get_maxpagesize'
...................................
*Synopsis*
bfd_vma bfd_emul_get_maxpagesize (const char *);

2.3.1.23 `bfd_emul_set_commonpagesize'
......................................
*Synopsis*
void bfd_emul_set_commonpagesize (const char *, bfd_vma);
*Description*
For ELF, set the common page size for the emulation. It is a no-op for
other formats.
2.3.1.24 `bfd_demangle'
.......................
*Synopsis*
char *bfd_demangle (bfd *, const char *, int);
*Description*
Wrapper around cplus_demangle. Strips leading underscores and other
such chars that would otherwise confuse the demangler. If passed a g++
v3 ABI mangled name, returns a buffer allocated with malloc holding the
demangled name. Returns NULL otherwise and on memory alloc failure.
2.3.1.25 `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. */
file_ptr (*bread) (struct bfd *abfd, void *ptr, file_ptr nbytes);
file_ptr (*bwrite) (struct bfd *abfd, const void *ptr,
file_ptr nbytes);
/* Return the current IOSTREAM file offset, or -1 (setting `bfd_error'
if an error occurs. */
file_ptr (*btell) (struct bfd *abfd);
/* For the following, on successful completion a value of 0 is returned.
Otherwise, a value of -1 is returned (and `bfd_error' is set). */
int (*bseek) (struct bfd *abfd, file_ptr offset, int whence);
int (*bclose) (struct bfd *abfd);
int (*bflush) (struct bfd *abfd);
int (*bstat) (struct bfd *abfd, struct stat *sb);
/* Mmap a part of the files. ADDR, LEN, PROT, FLAGS and OFFSET are the usual
mmap parameter, except that LEN and OFFSET do not need to be page
aligned. Returns (void *)-1 on failure, mmapped address on success.
Also write in MAP_ADDR the address of the page aligned buffer and in
MAP_LEN the size mapped (a page multiple). Use unmap with MAP_ADDR and
MAP_LEN to unmap. */
void *(*bmmap) (struct bfd *abfd, void *addr, bfd_size_type len,
int prot, int flags, file_ptr offset,
void **map_addr, bfd_size_type *map_len);
};
extern const struct bfd_iovec _bfd_memory_iovec;
2.3.1.26 `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).
2.3.1.27 `bfd_get_size'
.......................
*Synopsis*
file_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?".
2.3.1.28 `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*
void bfd_init (void);
*Description*
This routine must be called before any other BFD function to initialize
magical internal data structures.

File: bfd.info, Node: Sections, Next: Symbols, Prev: Initialization, Up: BFD front end
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'.

* Section Input::
* Section Output::
* typedef asection::
* section prototypes::

File: bfd.info, Node: Section Input, Next: Section Output, Prev: Sections, Up: Sections
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. An IEEE-695 file doesn't
contain raw data in sections, but data and relocation expressions
intermixed, so the data area has to be parsed to get out the data and
relocations.

File: bfd.info, Node: Section Output, Next: typedef asection, Prev: Section Input, Up: Sections
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 --------|
2.6.3 Link orders
-----------------
The data within a section is stored in a "link_order". These are much
like the fixups in `gas'. The link_order abstraction allows a section
to grow and shrink within itself.
A link_order knows how big it is, and which is the next link_order
and where the raw data for it is; it also points to a list of
relocations which apply to it.
The link_order is used by the linker to perform relaxing on final
code. The compiler creates code which is as big as necessary to make
it work without relaxing, and the user can select whether to relax.
Sometimes relaxing takes a lot of time. The linker runs around the
relocations to see if any are attached to data which can be shrunk, if
so it does it on a link_order by link_order basis.

the symbol to it, and builds a relocation. To build the lists

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*
bfd_boolean bfd_set_section_flags
(bfd *abfd, asection *sec, flagword flags);
*Description*
Set the attributes of the section SEC in the BFD ABFD 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
(bfd *abfd, asection *sec, const char *newname);
*Description*
Rename section SEC in ABFD 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:
section *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,
bfd_boolean (*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*
bfd_boolean bfd_set_section_size
(bfd *abfd, 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*
bfd_boolean 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 DATA. The data is written to the output section
starting at offset OFFSET for COUNT octets.
Normally `TRUE' is returned, else `FALSE'. 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.
* 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*
bfd_boolean 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*
bfd_boolean 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*
bfd_boolean 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*

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 `asymbol's. 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.

File: bfd.info, Node: Writing Symbols, Next: Mini Symbols, Prev: Reading Symbols, Up: Symbols
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:

{
/* 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

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.
Archive contents of output BFDs are chained through the `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*
bfd_boolean 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.

2.9 File formats
================
A format is a BFD concept of high level file contents type. The formats
supported by BFD are:
* `bfd_object'
The BFD may contain data, symbols, relocations and debug info.
* `bfd_archive'
The BFD contains other BFDs and an optional index.
* `bfd_core'
The BFD contains the result of an executable core dump.
2.9.1 File format functions
---------------------------
2.9.1.1 `bfd_check_format'
..........................
*Synopsis*
bfd_boolean 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*
bfd_boolean 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*
bfd_boolean 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.

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. *Note
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

* `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 bfd_symbol; /* Forward declaration. */
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
external idea of what a reloc number is stored
in this field. For example, a PC relative word relocation
in a coff environment has the type 023 - because that's
what the outside world calls a R_PCRWORD reloc. */
unsigned int type;
/* The value the final relocation is shifted right by. This drops
unwanted data from the relocation. */
unsigned int rightshift;
/* The size of the item to be relocated. This is *not* a
power-of-two measure. To get the number of bytes operated
on by a type of relocation, use bfd_get_reloc_size. */
int size;
/* The number of bits in the item to be relocated. This is used
when doing overflow checking. */
unsigned int bitsize;
/* The relocation is relative to the field being relocated. */
bfd_boolean pc_relative;
/* The bit position of the reloc value in the destination.
The relocated value is left shifted by this amount. */
unsigned int bitpos;
/* What type of overflow error should be checked for when
relocating. */
enum complain_overflow complain_on_overflow;
/* 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 (e.g., i960 callj
instructions). */
bfd_reloc_status_type (*special_function)
(bfd *, arelent *, struct bfd_symbol *, void *, asection *,
bfd *, char **);
/* The textual name of the relocation type. */
char *name;
/* 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. */
bfd_boolean partial_inplace;
/* 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 be zero. Non-zero values for ELF USE_RELA targets are
bogus as in those cases the value in the dst_mask part of the
section contents should be treated as garbage. */

empty (e.g., m88k bcs); this flag signals the fact. */

2.10.1.3 `The HOWTO Macro'
..........................
*Description*
The HOWTO define is horrible and will go away.
#define HOWTO(C, R, S, B, P, BI, O, SF, NAME, INPLACE, MASKSRC, MASKDST, PC) \
{ (unsigned) C, R, S, B, P, BI, O, SF, NAME, INPLACE, MASKSRC, MASKDST, PC }
*Description*
And will be replaced with the totally magic way. But for the moment, we
are compatible, so do it this way.
#define NEWHOWTO(FUNCTION, NAME, SIZE, REL, IN) \
HOWTO (0, 0, SIZE, 0, REL, 0, complain_overflow_dont, FUNCTION, \
NAME, FALSE, 0, 0, IN)
*Description*
This is used to fill in an empty howto entry in an array.
#define EMPTY_HOWTO(C) \
HOWTO ((C), 0, 0, 0, FALSE, 0, complain_overflow_dont, NULL, \
NULL, FALSE, 0, 0, FALSE)
*Description*
Helper routine to turn a symbol into a relocation value.
#define HOWTO_PREPARE(relocation, symbol) \
{ \
if (symbol != NULL) \
{ \
if (bfd_is_com_section (symbol->section)) \
{ \
relocation = 0; \
} \
else \
{ \
relocation = symbol->value; \
} \
} \
}
2.10.1.4 `bfd_get_reloc_size'
.............................
*Synopsis*
unsigned int bfd_get_reloc_size (reloc_howto_type *);
*Description*
For a reloc_howto_type that operates on a fixed number of bytes, this
returns the number of bytes operated on.
2.10.1.5 `arelent_chain'
........................
*Description*
How relocs are tied together in an `asection':
typedef struct relent_chain
{
arelent relent;
struct relent_chain *next;
}
arelent_chain;
2.10.1.6 `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'.
2.10.1.7 `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. The
ERROR_MESSAGE argument is set to an error message if this return
`bfd_reloc_dangerous'.
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_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.
The 24-bit relocation is used in some Intel 960 configurations.
-- : BFD_RELOC_32_SECREL
Section relative relocations. Some targets need this for DWARF2.
-- : BFD_RELOC_32_GOT_PCREL

-- : BFD_RELOC_RVA
Linkage-table relative.
-- : BFD_RELOC_8_FFnn
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.

Reloc types used for i960/b.out.

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

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.

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.

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_BRANCH7

-- : 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

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.

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:
* Create a BFD by calling the internal routine `_bfd_new_bfd', then
call `bfd_find_target' with the target string supplied to
`bfd_openr' and the new BFD pointer.
* If a null target string was provided to `bfd_find_target', look up
the environment variable `GNUTARGET' and use that as the target
string.
* If the target string is still `NULL', or the target string is
`default', then use the first item in the target vector as the
target type, and set `target_defaulted' in the BFD to cause
`bfd_check_format' to loop through all the targets. *Note
bfd_target::. *Note Formats::.
* Otherwise, inspect the elements in the target vector one by one,
until a match on target name is found. When found, use it.
* Otherwise return the error `bfd_error_invalid_target' to
`bfd_openr'.
* `bfd_openr' attempts to open the file using `bfd_open_file', and
returns the BFD.
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.
* Menu:
* bfd_target::

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
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_set_default_target'
.................................
*Synopsis*
bfd_boolean 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.
2.12.1.2 `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.
2.12.1.3 `bfd_get_target_info'
..............................
*Synopsis*
const bfd_target *bfd_get_target_info (const char *target_name,
bfd *abfd,
bfd_boolean *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.
2.12.1.4 `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.
2.12.1.5 `bfd_seach_for_target'
...............................
*Synopsis*
const bfd_target *bfd_search_for_target
(int (*search_func) (const bfd_target *, void *),
void *);
*Description*
Return a pointer to the first transfer vector in the list of transfer
vectors maintained by BFD that produces a non-zero result when passed
to the function SEARCH_FUNC. The parameter DATA is passed, unexamined,
to the search function.

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, 2 and 3 for Intel i960 KA and
i960 KB, and 68020 and 68030 for Motorola 68020 and 68030.

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.
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.
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_close'd, 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.
2.14.1.4 `bfd_openstreamr'
..........................
*Synopsis*
bfd *bfd_openstreamr (const char *, const char *, void *);
*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.
2.14.1.5 `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'.
2.14.1.6 `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'.
2.14.1.7 `bfd_close'
....................
*Synopsis*
bfd_boolean 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'.
2.14.1.8 `bfd_close_all_done'
.............................
*Synopsis*
bfd_boolean 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'.
2.14.1.9 `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'.
2.14.1.10 `bfd_make_writable'
.............................
*Synopsis*
bfd_boolean 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'.
2.14.1.11 `bfd_make_readable'
.............................
*Synopsis*
bfd_boolean 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'.
2.14.1.12 `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.
2.14.1.13 `bfd_alloc2'
......................
*Synopsis*
void *bfd_alloc2 (bfd *abfd, bfd_size_type nmemb, bfd_size_type size);
*Description*
Allocate a block of NMEMB elements of SIZE bytes each 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.
2.14.1.15 `bfd_zalloc2'
.......................
*Synopsis*
void *bfd_zalloc2 (bfd *abfd, bfd_size_type nmemb, bfd_size_type size);
*Description*
Allocate a block of NMEMB elements of SIZE bytes each of zeroed memory
attached to `abfd' and return a pointer to it.
2.14.1.16 `bfd_calc_gnu_debuglink_crc32'
........................................
*Synopsis*
unsigned long bfd_calc_gnu_debuglink_crc32
(unsigned long crc, const unsigned char *buf, bfd_size_type len);
*Description*
Computes a CRC value as used in the .gnu_debuglink section. Advances
the previously computed CRC value by computing and adding in the crc32
for LEN bytes of BUF.
*Returns*
Return the updated CRC32 value.
2.14.1.17 `get_debug_link_info'
...............................
*Synopsis*
char *get_debug_link_info (bfd *abfd, unsigned long *crc32_out);
*Description*
fetch the filename and CRC32 value for any separate debuginfo
associated with ABFD. Return NULL if no such info found, otherwise
return filename and update CRC32_OUT.

Checks to see if NAME is a file and if its contents match CRC32.
2.14.1.19 `find_separate_debug_file'
....................................
*Synopsis*
char *find_separate_debug_file (bfd *abfd);
*Description*
Searches ABFD for a reference to separate debugging information, scans
various locations in the filesystem, including the file tree rooted at
DEBUG_FILE_DIRECTORY, and returns a filename of such debugging
information if the file is found and has matching CRC32. Returns NULL
if no reference to debugging file exists, or file cannot be found.
2.14.1.20 `bfd_follow_gnu_debuglink'
....................................
*Synopsis*
char *bfd_follow_gnu_debuglink (bfd *abfd, const char *dir);
*Description*
Takes a BFD and searches it for a .gnu_debuglink section. If this
section is found, it examines the section for the name and checksum of
a '.debug' file containing auxiliary debugging information. It then
searches the filesystem for this .debug file in some standard
locations, including the directory tree rooted at DIR, and if found
returns the full filename.
If DIR is NULL, it will search a default path configured into libbfd
at build time. [XXX this feature is not currently implemented].
*Returns*
`NULL' on any errors or failure to locate the .debug file, otherwise a
pointer to a heap-allocated string containing the filename. The caller
is responsible for freeing this string.
2.14.1.21 `bfd_create_gnu_debuglink_section'
............................................
*Synopsis*
struct bfd_section *bfd_create_gnu_debuglink_section
(bfd *abfd, const char *filename);
*Description*
Takes a BFD and adds a .gnu_debuglink section to it. The section is
sized to be big enough to contain a link to the specified FILENAME.
*Returns*
A pointer to the new section is returned if all is ok. Otherwise
`NULL' is returned and bfd_error is set.
2.14.1.22 `bfd_fill_in_gnu_debuglink_section'
.............................................
*Synopsis*
bfd_boolean bfd_fill_in_gnu_debuglink_section
(bfd *abfd, struct bfd_section *sect, const char *filename);
*Description*
Takes a BFD and containing a .gnu_debuglink section SECT and fills in
the contents of the section to contain a link to the specified
FILENAME. The filename should be relative to the current directory.
*Returns*
`TRUE' is returned if all is ok. Otherwise `FALSE' is returned and
bfd_error is set.

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

2.16 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.
2.16.1 Caching functions

all is well.
2.16.1.3 `bfd_cache_close_all'
..............................
*Synopsis*
bfd_boolean bfd_cache_close_all (void);
*Description*
Remove all BFDs from the cache. If the attached file is open, then

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.

File: bfd.info, Node: Linker Functions, Next: Hash Tables, Prev: File Caching, Up: BFD front end
2.17 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.

File: bfd.info, Node: Creating a Linker Hash Table, Next: Adding Symbols to the Hash Table, Prev: Linker Functions, Up: Linker Functions
2.17.1 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'. *Note 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.

File: bfd.info, Node: Adding Symbols to the Hash Table, Next: Performing the Final Link, Prev: Creating a Linker Hash Table, Up: Linker Functions
2.17.2 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)'.

* Adding symbols from an object file::
* Adding symbols from an archive::

File: bfd.info, Node: Differing file formats, Next: Adding symbols from an object file, Prev: Adding Symbols to the Hash Table, Up: Adding Symbols to the Hash Table
2.17.2.1 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.

File: bfd.info, Node: Adding symbols from an object file, Next: Adding symbols from an archive, Prev: Differing file formats, Up: Adding Symbols to the Hash Table
2.17.2.2 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.

File: bfd.info, Node: Adding symbols from an archive, Prev: Adding symbols from an object file, Up: Adding Symbols to the Hash Table
2.17.2.3 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.
This function builds a hash table from the archive symbol table and
looks through the list of undefined symbols to see which elements
should be included. `_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.
The function passed to `_bfd_generic_link_add_archive_symbols' must
read the symbols of the archive element and decide whether the archive
element should be included in the link. 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. The
`add_archive_element' callback has the option to indicate that it would
like to replace the element archive with a substitute BFD, in which
case it is the symbols of that substitute BFD that must be added to the
linker hash table instead.
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.

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

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

File: bfd.info, Node: Relocating the section contents, Next: Writing the symbol table, Prev: Information provided by the linker, Up: Performing the Final Link
2.17.3.2 Relocating the section contents
........................................
The `_bfd_final_link' function should look through the `link_order'
structures attached to each section of the output file. Each
`link_order' structure should either be handled specially, or it should
be passed to the function `_bfd_default_link_order' which will do the
right thing (`_bfd_default_link_order' is defined in `linker.c').
For efficiency, a `link_order' of type `bfd_indirect_link_order'
whose associated section belongs to a BFD of the same format as the
output BFD must be handled specially. This type of `link_order'
describes part of an output section in terms of a section belonging to
one of the input files. The `_bfd_final_link' function should read the
contents of the section and any associated relocs, apply the relocs to
the section contents, and write out the modified section contents. If
performing a relocatable link, the relocs themselves must also be
modified and written out.
The functions `_bfd_relocate_contents' and
`_bfd_final_link_relocate' provide some general support for performing
the actual relocations, notably overflow checking. Their arguments
include information about the symbol the relocation is against and a
`reloc_howto_type' argument which describes the relocation to perform.
These functions are defined in `reloc.c'.
The a.out function which handles reading, relocating, and writing
section contents is `aout_link_input_section'. The actual relocation
is done in `aout_link_input_section_std' and
`aout_link_input_section_ext'.

File: bfd.info, Node: Writing the symbol table, Prev: Relocating the section contents, Up: Performing the Final Link
2.17.3.3 Writing the symbol table
.................................
The `_bfd_final_link' function must gather all the symbols in the input
files and write them out. It must also write out all the symbols in
the global hash table. This must be controlled by the `strip' and
`discard' fields of the `bfd_link_info' structure.
The local symbols of the input files will not have been entered into
the linker hash table. The `_bfd_final_link' routine must consider
each input file and include the symbols in the output file. It may be
convenient to do this when looking through the `link_order' structures,
or it may be done by stepping through the `input_bfds' list.
The `_bfd_final_link' routine must also traverse the global hash
table to gather all the externally visible symbols. It is possible
that most of the externally visible symbols may be written out when
considering the symbols of each input file, but it is still necessary
to traverse the hash table since the linker script may have defined
some symbols that are not in any of the input files.
The `strip' field of the `bfd_link_info' structure controls which
symbols are written out. The possible values are listed in
`bfdlink.h'. If the value is `strip_some', then the `keep_hash' field
of the `bfd_link_info' structure is a hash table of symbols to keep;
each symbol should be looked up in this hash table, and only symbols
which are present should be included in the output file.
If the `strip' field of the `bfd_link_info' structure permits local
symbols to be written out, the `discard' field is used to further
controls which local symbols are included in the output file. If the
value is `discard_l', then all local symbols which begin with a certain
prefix are discarded; this is controlled by the
`bfd_is_local_label_name' entry point.
The a.out backend handles symbols by calling
`aout_link_write_symbols' on each input BFD and then traversing the
global hash table with the function `aout_link_write_other_symbol'. It
builds a string table while writing out the symbols, which is written
to the output file at the end of `NAME(aout,final_link)'.

2.18 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'.

2.18.1 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'. *Note 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.

File: bfd.info, Node: Looking Up or Entering a String, Next: Traversing a Hash Table, Prev: Creating and Freeing a Hash Table, Up: Hash Tables
2.18.2 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.

File: bfd.info, Node: Traversing a Hash Table, Next: Deriving a New Hash Table Type, Prev: Looking Up or Entering a String, Up: Hash Tables
2.18.3 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.

File: bfd.info, Node: Deriving a New Hash Table Type, Prev: Traversing a Hash Table, Up: Hash Tables
2.18.4 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.

2.18.4.1 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'.

File: bfd.info, Node: Write the Derived Creation Routine, Next: Write Other Derived Routines, Prev: Define the Derived Structures, Up: Deriving a New Hash Table Type
2.18.4.2 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'.

File: bfd.info, Node: Write Other Derived Routines, Prev: Write the Derived Creation Routine, Up: Deriving a New Hash Table Type
2.18.4.3 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.

=====================
All of BFD lives in one directory.

File: bfd.info, Node: aout, Next: coff, Prev: What to Put Where, Up: BFD back ends
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, 386 and 29k 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, `newsos3.c' for
the Sony NEWS, 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 sunos_big_vec
#include "aoutf1.h"
requires all the names from `aout32.c', and produces the jump vector
sunos_big_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.in' 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 (used on 29ks and sparcs) 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).

3.3 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 88k bcs
coff format is implemented in the file `coff-m88k.c'. This file
`#include's `coff/m88k.h' which defines the external structure of the
coff format for the 88k, and `coff/internal.h' which defines the
internal structure. `coff-m88k.c' also defines the relocations used by
the 88k format *Note Relocations::.
The Intel i960 processor version of coff is implemented in
`coff-i960.c'. This file has the same structure as `coff-m88k.c',
except that it includes `coff/i960.h' rather than `coff-m88k.h'.
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 `#ifdef's
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.
For example, `coff-i960.c' includes `coff/internal.h' and
`coff/i960.h'. It then defines a few constants, such as `I960', and
includes `coffcode.h'. Since the i960 has complex relocation types,
`coff-i960.c' also includes some code to manipulate the i960 relocs.
This code is not in `coffcode.h' because it would not be used by any
other target.
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. `#define'ing `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'. *Note 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' *Note 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 and 960 use the
`r_type' to directly produce an index into a howto table vector;
the 88k subtracts a number from the `r_type' field and creates an
addend field.

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://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz'
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://www-cs-faculty.stanford.edu/~knuth/mmix.html' for more
information about MMIX. The ELF format is used for intermediate object
files in the BFD implementation.

File: bfd.info, Node: File layout, Next: Symbol-table, Prev: mmo, Up: mmo
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. *Note 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. *Note 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://www-cs-faculty.stanford.edu/~knuth/mmixal-intro.ps.gz', 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.
`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'. *Note 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 (*note
Symbol-table::).
`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'.

: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.

3.5.2 Symbol table format
-------------------------
From mmixal.w (or really, the generated mmixal.tex) in
`http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz'):
"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 (*note 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.

Copyright (C) 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.
`http://fsf.org/'
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
0. 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.
1. 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.
2. 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.
3. 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.
4. 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:
A. 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.
B. 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.
C. State on the Title page the name of the publisher of the
Modified Version, as the publisher.
D. Preserve all the copyright notices of the Document.
E. Add an appropriate copyright notice for your modifications
adjacent to the other copyright notices.
F. 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.
G. Preserve in that license notice the full lists of Invariant
Sections and required Cover Texts given in the Document's
license notice.
H. Include an unaltered copy of this License.
I. 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.
J. 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.
K. 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.
L. 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.
M. Delete any section Entitled "Endorsements". Such a section
may not be included in the Modified Version.
N. Do not retitle any existing section to be Entitled
"Endorsements" or to conflict in title with any Invariant
Section.
O. 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.
5. 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."
6. 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.
7. 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.
8. 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.
9. 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.
10. 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.
11. 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
