GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
675 Mass Ave, Cambridge, MA 02139, USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public 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.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
Appendix: How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) 19yy <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) 19yy name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

Preliminary Notes on Porting BFD
--------------------------------
The 'host' is the system a tool runs *on*.
The 'target' is the system a tool runs *for*, i.e.
a tool can read/write the binaries of the target.
Porting to a new host
---------------------
Pick a name for your host. Call that <host>.
(<host> might be sun4, ...)
Create a file hosts/<host>.mh.
Porting to a new target
-----------------------
Pick a name for your target. Call that <target>.
Call the name for your CPU architecture <cpu>.
You need to create <target>.c and config/<target>.mt,
and add a case for it to a case statements in bfd/configure.host and
bfd/config.bfd, which associates each canonical host type with a BFD
host type (used as the base of the makefile fragment names), and to the
table in bfd/configure.in which associates each target vector with
the .o files it uses.
config/<target>.mt is a Makefile fragment.
The following is usually enough:
DEFAULT_VECTOR=<target>_vec
SELECT_ARCHITECTURES=bfd_<cpu>_arch
See the list of cpu types in archures.c, or "ls cpu-*.c".
If your architecture is new, you need to add it to the tables
in bfd/archures.c, opcodes/configure.in, and binutils/objdump.c.
For more information about .mt and .mh files, see config/README.
The file <target>.c is the hard part. It implements the
bfd_target <target>_vec, which includes pointers to
functions that do the actual <target>-specific methods.
Porting to a <target> that uses the a.out binary format
-------------------------------------------------------
In this case, the include file aout-target.h probaby does most
of what you need. The program gen-aout generates <target>.c for
you automatically for many a.out systems. Do:
make gen-aout
./gen-aout <target> > <target>.c
(This only works if you are building on the target ("native").
If you must make a cross-port from scratch, copy the most
similar existing file that includes aout-target.h, and fix what is wrong.)
Check the parameters in <target>.c, and fix anything that is wrong.
(Also let us know about it; perhaps we can improve gen-aout.c.)
TARGET_IS_BIG_ENDIAN_P
Should be defined if <target> is big-endian.
N_HEADER_IN_TEXT(x)
See discussion in ../include/aout/aout64.h.
BYTES_IN_WORD
Number of bytes per word. (Usually 4 but can be 8.)
ARCH
Number of bits per word. (Usually 32, but can be 64.)
ENTRY_CAN_BE_ZERO
Define if the extry point (start address of an
executable program) can be 0x0.
TEXT_START_ADDR
The address of the start of the text segemnt in
virtual memory. Normally, the same as the entry point.
TARGET_PAGE_SIZE
SEGMENT_SIZE
Usually, the same as the TARGET_PAGE_SIZE.
Alignment needed for the data segment.
TARGETNAME
The name of the target, for run-time lookups.
Usually "a.out-<target>"

Things that still need to be done: -*- Text -*-
o - A source of space lossage is that all the target-dependent code
is in a single bfd_target structure. Hence all the code for
*writing* object files is still pulled into all the applications
that only care about *reading* (gdb, nm, objdump), while gas has
to carry along all the unneded baggage for reading objects. And
so on. This would be a substantial change, and the payoff would
not all that great (essentially none if bfd is used as a shared
library).
o - The storage needed by BFD data structures is also larger than strictly
needed. This may be difficult to do much about.
o - implement bfd_abort, which should close the bfd but not alter the
filesystem.
o - update the bfd doc; write a how-to-write-a-backend doc, take out
the stupid quips and fill in all the blanks.
o - upgrade the reloc handling as per Steve's suggestion.

SECTION
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
@file{config/@var{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 @file{archures.c}.

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.

/* This is a BFD backend which may be used to write binary objects.
It may only be used for output, not input. The intention is that
this may be used as an output format for objcopy in order to
generate raw binary data.
This is very simple. The only complication is that the real data
will start at some address X, and in some cases we will not want to
include X zeroes just to get to that point. Since the start
address is not meaningful for this object file format, we use it
instead to indicate the number of zeroes to skip at the start of
the file. objcopy cooperates by specially setting the start
address to zero by default. */

SECTION
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.

# config.bfd
# Convert a canonical host type into a BFD host type.
# Set shell variable targ to canonical target name, and run
# using ``. config.bfd''.
# Sets the following shell variables:
# targ_defvec Default vector for this target
# targ_selvecs Vectors to build for this target
# targ_archs Architectures for this target
# targ_cflags $(CFLAGS) for this target (FIXME: pretty bogus)
# targ_undercore Whether underscores are used: yes or no
# The binutils c++filt program wants to know whether underscores are
# stripped or not. That is why we set targ_underscore. c++filt uses
# this information to choose a default. This information is
# duplicated in the symbol_leading_char field of the BFD target
# vector, but c++filt does not deal with object files and is not
# linked against libbfd.a. It is not terribly important that c++filt
# get this right; it is just convenient.

# HOST_64BIT_TYPE host 64 bit type
# SHLIB_CC compiler to use when building shared library
# SHLIB_CFLAGS flags to use when building shared library

Fri Nov 5 10:58:53 1993 David J. Mackenzie (djm@thepub.cygnus.com)
* bfd.texinfo: Small cleanups.
Fri Nov 19 03:46:11 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

it must run on the build machine.
Tue Apr 6 22:38:10 1993 John Gilmore (gnu@cygnus.com)
* Makefile.in (chew): Don't compile from .c to executable in a
single step; it puts a temporary .o filename into the executable,
which makes multi-stage comparisons fail. Compile chew.c to
chew.o, and link that, which makes identical executables every time.
Wed Mar 24 17:26:29 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
* Makefile.in: fix typo (bfd.texinfo not bfd.texino)
Fri Mar 19 01:13:00 1993 Ken Raeburn (raeburn@kr-pc.cygnus.com)
* bfd.texinfo: Since BFD version number has been bumped, do same
to "version number" on title page, and elsewhere. Should be
fixed to extract real version number.
Tue Mar 16 12:15:13 1993 Per Bothner (bothner@rtl.cygnus.com)
* Makefile.in: Add *clean rules.
Mon Jan 11 18:43:56 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
* Makefile.in (libbfd.h): Removed duplicate init.c and libbfd.c.
Added seclet.c.
(bfd.h): Added dependency on bfd.c and seclet.c. Added seclet.c
to build.
Thu Dec 17 19:35:43 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
* Makefile.in: added dvi target, define and use $(TEXI2DVI)
Thu Dec 3 17:42:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
* Makefile.in (TEXIDIR): New variable.
(bfd.dvi): Look for bfd.texinfo in $(srcdir). Generate index.
* bfd.texinfo: Minor doc fixes.
Thu Nov 5 03:13:55 1992 John Gilmore (gnu@cygnus.com)
Cleanup: Replace all uses of EXFUN in the BFD sources, with PARAMS.
* doc/chew.c (exfunstuff): Eliminate.
(paramstuff): Replace exfunstuff with function to generate PARAMS.
* doc/proto.str: Use paramstuff rather than exfunstuff.
Mon Aug 17 12:40:32 1992 Steve Chamberlain (sac@thepub.cygnus.com)
* chew.c: various patches provided by Howard Chu.
Fri Jun 19 18:59:54 1992 John Gilmore (gnu at cygnus.com)
* Makefile.in (libbfd.h): Add elf.c as a source of prototypes.
Mon May 11 18:55:59 1992 John Gilmore (gnu at cygnus.com)
* chew.c: exit() should be declared by config files, not by
portable source code. Its type could be int or void function.
Mon May 4 13:45:57 1992 K. Richard Pixley (rich@rtl.cygnus.com)
* Makefile.in: another CFLAGS correction.
Tue Apr 28 10:21:32 1992 K. Richard Pixley (rich@rtl.cygnus.com)
* Makefile.in: Do the CFLAGS thing.
Fri Apr 10 22:34:52 1992 Fred Fish (fnf@cygnus.com)
* Makefile.in (MINUS_G): Add macro and default to -g.
Fri Mar 6 18:53:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
* chew.c: now has -w switch turn on warnings
Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
* Makefile.in, configure.in: removed traces of namesubdir,
-subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
copyrights to '92, changed some from Cygnus to FSF.
Tue Dec 10 22:11:05 1991 K. Richard Pixley (rich at rtl.cygnus.com)
* Makefile.in: build chew into the current directory. Complete
the MKDOC macro transition.
Tue Dec 10 08:26:28 1991 Steve Chamberlain (sac at rtl.cygnus.com)
* chew.c: don't core dump when can't open file
* Makefile.in: get proto.str from the right place when built in
odd directories

* Makefile.in: infodir belongs in datadir.
Sat Dec 7 17:01:23 1991 Steve Chamberlain (sac at rtl.cygnus.com)
* chew.c: Much modified
* proto.str, doc.str: New files for extracting to product
prototypes and documents respectively.
Fri Dec 6 22:57:12 1991 K. Richard Pixley (rich at rtl.cygnus.com)
* Makefile.in: added standards.text support, host/site/target
inclusion hooks, install using INSTALL_DATA rather than cp,
don't echo on install.
Thu Dec 5 22:46:17 1991 K. Richard Pixley (rich at rtl.cygnus.com)
* Makefile.in: idestdir and ddestdir go away. Added copyrights
and shift gpl to v2. Added ChangeLog if it didn't exist. docdir
and mandir now keyed off datadir by default.

@chapter Introduction
@cindex BFD
@cindex what is it?
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).
@itemize @bullet
@item 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.
@item 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.

@node History, How It Works, Overview, Overview
@section 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 (@code{sac@@cygnus.com}), John Gilmore
(@code{gnu@@cygnus.com}), K. Richard Pixley (@code{rich@@cygnus.com})
and David Henkel-Wallace (@code{gumby@@cygnus.com}).
@node How It Works, What BFD Version 2 Can Do, History, Overview
@section How To Use BFD
To use the library, include @file{bfd.h} and link with @file{libbfd.a}.
BFD provides a common interface to the parts of an object file
for a calling application.
When an application sucessfully opens a target file (object, archive, or
whatever), a pointer to an internal structure is returned. This pointer
points to a structure called @code{bfd}, described in
@file{bfd.h}. Our convention is to call this pointer a BFD, and
instances of it within code @code{abfd}. All operations on
the target object file are applied as methods to the BFD. The mapping is
defined within @code{bfd.h} in a set of macros, all beginning
with @samp{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
@code{abfd}.
@lisp
@c @cartouche
#include "bfd.h"
unsigned int number_of_sections(abfd)
bfd *abfd;
@{
return bfd_count_sections(abfd);
@}
@c @end cartouche
@end lisp
The abstraction used within BFD is that an object file has:
@itemize @bullet
@item
a header,
@item
a number of sections containing raw data (@pxref{Sections}),
@item
a set of relocations (@pxref{Relocations}), and
@item
some symbol information (@pxref{Symbols}).
@end itemize
@noindent
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.

@node Memory Usage, Initialization, BFD front end, BFD front end
@section 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
@code{bfd} structures become invalid on a @code{bfd_close}; for example,
after a @code{bfd_close} the vector passed to
@code{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 (@code{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.

@c This summary of BFD is shared by the BFD and LD docs.
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 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.

@emph{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
@code{b.out}. There is nowhere in an @code{a.out} format file to store
alignment information on the contained data, so when a file is linked
from @code{b.out} and an @code{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.,
@code{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.
@emph{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 @code{a.out} to
@code{b.out}. When a mixture of formats is linked, the information is
only lost from the files whose format differs from the destination.
@node Canonical format
@subsection 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.
@cindex BFD canonical format
@cindex internal object-file format
@table @emph
@item 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 @code{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.
@item 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.
@item 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. @code{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 @code{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.
@item 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.
@item 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).

SECTION
File formats
A format is a BFD concept of high level file contents type. The
formats supported by BFD are:
o <<bfd_object>>
The BFD may contain data, symbols, relocations and debug info.
o <<bfd_archive>>
The BFD contains other BFDs and an optional index.
o <<bfd_core>>
The BFD contains the result of an executable core dump.

FUNCTION
bfd_check_format
SYNOPSIS
boolean bfd_check_format(bfd *abfd, bfd_format format);
DESCRIPTION
Verify if the file attached to the BFD @var{abfd} is compatible
with the format @var{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:
o <<bfd_error_invalid_operation>> -
if <<format>> is not one of <<bfd_object>>, <<bfd_archive>> or
<<bfd_core>>.
o <<bfd_error_system_call>> -
if an error occured during a read - even some file mismatches
can cause bfd_error_system_calls.
o <<file_not_recognised>> -
none of the backends recognised the file format.
o <<bfd_error_file_ambiguously_recognized>> -
more than one backend recognised the file format.

SECTION
Hash Tables
@cindex 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>>.

SUBSECTION
Creating and freeing a hash table
@findex bfd_hash_table_init
@findex bfd_hash_table_init_n
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 @var{size} argument, may be used).
<<bfd_hash_table_init>> returns <<false>> if some sort of
error occurs.
@findex bfd_hash_newfunc
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>>. @xref{Deriving
a New Hash Table Type} for why you would want to use a
different value for this argument.
@findex bfd_hash_allocate
<<bfd_hash_table_init>> will create an obstack which will be
used to allocate new entries. You may allocate memory on this
obstack using <<bfd_hash_allocate>>.
@findex bfd_hash_table_free
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.
INODE
Looking Up or Entering a String, Traversing a Hash Table, Creating and Freeing a Hash Table, Hash Tables
SUBSECTION
Looking up or entering a string
@findex bfd_hash_lookup
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 @var{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 @var{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 @var{create} argument is <<true>>, and a new entry is
created, the @var{copy} argument is used to decide whether to
copy the string onto the hash table obstack or not. If
@var{copy} is passed as <<false>>, you must be careful not to
deallocate or modify the string as long as the hash table
exists.

SUBSECTION
Traversing a hash table
@findex bfd_hash_traverse
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.

SUBSECTION
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.

@* Write Other Derived Routines::
@end menu
INODE
Define the Derived Structures, Write the Derived Creation Routine, Deriving a New Hash Table Type, Deriving a New Hash Table Type
SUBSUBSECTION
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>>.
INODE
Write the Derived Creation Routine, Write Other Derived Routines, Define the Derived Structures, Deriving a New Hash Table Type
SUBSUBSECTION
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.
@var{function_name} is the name of the routine.
@var{entry_type} is the type of an entry in the hash table you
are creating. @var{base_newfunc} is the name of the creation
routine of the hash table type your hash table is derived
from.
EXAMPLE
.struct bfd_hash_entry *
.@var{function_name} (entry, table, string)
. struct bfd_hash_entry *entry;
. struct bfd_hash_table *table;
. const char *string;
.{
. struct @var{entry_type} *ret = (@var{entry_type} *) entry;
.
. {* Allocate the structure if it has not already been allocated by a

. if (ret == (@var{entry_type} *) NULL)
. {
. ret = ((@var{entry_type} *)
. bfd_hash_allocate (table, sizeof (@var{entry_type})));
. if (ret == (@var{entry_type} *) NULL)
. return NULL;
. }
.
. {* Call the allocation method of the base class. *}
. ret = ((@var{entry_type} *)
. @var{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.
@var{function_name} is <<_bfd_link_hash_newfunc>>.
@var{entry_type} is <<struct bfd_link_hash_entry>>.
@var{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>>.
INODE
Write Other Derived Routines, , Write the Derived Creation Routine, Deriving a New Hash Table Type
SUBSUBSECTION
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.

<<bfd_fdopenr>> is to <<bfd_fopenr>> much like <<fdopen>> is to <<fopen>>.
It opens a BFD on a file already described by the @var{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 @var{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 cacheing; 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>>.

SECTION
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>>.

@end menu
INODE
Section Input, Section Output, Sections, Sections
SUBSECTION
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.
INODE
Section Output, typedef asection, Section Input, Sections
SUBSECTION
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 --------|
SUBSECTION
Link orders
The data within a section is stored in a @dfn{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.

Run through @var{abfd} and return the one of the

This should only be used in special cases; the normal way to process
all sections of a given name is to use <<bfd_map_over_sections>> and
<<strcmp>> on the name (or better yet, base it on the section flags
or something else) for each section.

Targets
DESCRIPTION
Each port of BFD to a different machine requries 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:
o 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.
o If a null target string was provided to <<bfd_find_target>>,
look up the environment variable <<GNUTARGET>> and use
that as the target string.
o 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.
@xref{bfd_target}. @xref{Formats}.
o Otherwise, inspect the elements in the target vector
one by one, until a match on target name is found. When found,
use it.
o Otherwise return the error <<bfd_error_invalid_target>> to
<<bfd_openr>>.
o <<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.

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 @file{bfd.h}, and are also used when calling various
routines by hand inside the BFD implementation. The @var{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!

SYNOPSIS

DESCRIPTION
Return a pointer to the transfer vector for the object target
named @var{target_name}. If @var{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. This causes <<bfd_check_format>> to loop over all the
targets to find the one that matches the file being read.

from *u_ar0. The other is that u_ar0 is sometimes an absolute address
in kernel memory, and on other systems it is an offset from the beginning
of the `struct user'.
As a practical matter, we don't know where the registers actually are,
so we have to pass the whole area to GDB. We encode the value of u_ar0
by setting the .regs section up so that its virtual memory address
0 is at the place pointed to by u_ar0 (by setting the vma of the start
of the section to -u_ar0). GDB uses this info to locate the regs,
using minor trickery to get around the offset-or-absolute-addr problem. */

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
675 Mass Ave, Cambridge, MA 02139, USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public 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.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
Appendix: How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) 19yy <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) 19yy name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

that don't count the exec header as part
of the text segment, to be consistent with bfd.
* a.out.sun4.h: Simplified/fixed for previous change.

/* ANSI and traditional C compatibility macros
ANSI C is assumed if __STDC__ is #defined.
Macro ANSI C definition Traditional C definition
----- ---- - ---------- ----------- - ----------
PTR `void *' `char *'
LONG_DOUBLE `long double' `double'
VOLATILE `volatile' `'
SIGNED `signed' `'
PTRCONST `void *const' `char *'
ANSI_PROTOTYPES 1 not defined
CONST is also defined, but is obsolete. Just use const.
DEFUN (name, arglist, args)
Defines function NAME.
ARGLIST lists the arguments, separated by commas and enclosed in
parentheses. ARGLIST becomes the argument list in traditional C.
ARGS list the arguments with their types. It becomes a prototype in
ANSI C, and the type declarations in traditional C. Arguments should
be separated with `AND'. For functions with a variable number of
arguments, the last thing listed should be `DOTS'.
DEFUN_VOID (name)
Defines a function NAME, which takes no arguments.
obsolete -- EXFUN (name, (prototype)) -- obsolete.
Replaced by PARAMS. Do not use; will disappear someday soon.
Was used in external function declarations.
In ANSI C it is `NAME PROTOTYPE' (so PROTOTYPE should be enclosed in
parentheses). In traditional C it is `NAME()'.
For a function that takes no arguments, PROTOTYPE should be `(void)'.
PARAMS ((args))
We could use the EXFUN macro to handle prototype declarations, but
the name is misleading and the result is ugly. So we just define a
simple macro to handle the parameter lists, as in:
static int foo PARAMS ((int, char));
This produces: `static int foo();' or `static int foo (int, char);'
EXFUN would have done it like this:
static int EXFUN (foo, (int, char));
but the function is not external...and it's hard to visually parse
the function name out of the mess. EXFUN should be considered
obsolete; new code should be written to use PARAMS.
For example:
extern int printf PARAMS ((CONST char *format DOTS));
int DEFUN(fprintf, (stream, format),
FILE *stream AND CONST char *format DOTS) { ... }
void DEFUN_VOID(abort) { ... }

* If N_HEADER_IN_TEXT(x) is true (which defaults to being the
case when the entry point is EXEC_BYTES_SIZE or further into a page):
no padding is needed; text can start after exec header. Sun
considers the text segment of such files to include the exec header;
for BFD's purposes, we don't, which makes more work for us.
start at TEXT_START_ADDR + EXEC_BYTES_SIZE, offset is EXEC_BYTES_SIZE,
size as stated minus EXEC_BYTES_SIZE.
* If N_HEADER_IN_TEXT(x) is false (which defaults to being the case when
the entry point is less than EXEC_BYTES_SIZE into a page (e.g. page
aligned)): (padding is needed so that text can start at a page boundary)
start at TEXT_START_ADDR, offset TARGET_PAGE_SIZE, size as stated.
Specific configurations may want to hardwire N_HEADER_IN_TEXT,
for efficiency or to allow people to play games with the entry point.
In that case, you would #define N_HEADER_IN_TEXT(x) as 1 for sunos,
and as 0 for most other hosts (Sony News, Vax Ultrix, etc).
(Do this in the appropriate bfd target file.)
(The default is a heuristic that will break if people try changing
the entry point, perhaps with the ld -e flag.)
* QMAGIC is always like a ZMAGIC for which N_HEADER_IN_TEXT is true,
and for which the starting address is TARGET_PAGE_SIZE (or should this be
SEGMENT_SIZE?) (TEXT_START_ADDR only applies to ZMAGIC, not to QMAGIC).
