- GNU GENERAL PUBLIC LICENSE
- Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
- 59 Temple Place, Suite 330, Boston, MA 02111-1307 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
-
- 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., 59 Temple Place, Suite 330, Boston, MA 02111-1307 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.

-
- * elf32-hppa.c (hppa_elf_reloc): Target register for a 'jump
- in delay slot' optimization in combination with a long call
- stub should always be r31.
-
- * elf32-hppa.c: (hppa_elf_relocate_insn): To be consistent
- across all relocation types, retrieve instruction addends from
- the relocation entry rather than from the instruction itself.
-
- * elf32-hppa.c: (hppa_elf_relocate_insn): Fix a relocation
- error that only occurred when the addend of an 'addil' or
- 'ldil' was larger than 21 bits and very close to a 2K byte
- boundary.
-
- * elf32-hppa.c: (hppa_elf_reloc): Handle the optimization in
- which a jump is placed in the delay slot of a function call.
- The jump was being accomplished via an adjustment to the
- return pointer. This optimization would break the long call
- stub code, if there was any.
-
- * elf32-hppa.c: (hppa_elf_build_long_branch_stub): Corrections
- to long branch stubs to avoid use of general register 2.
-

- alignments.
-

- many utilities. Set assorted SEC_* flags for SOM subspaces
- which correspond to BFD sections.
-
- * elf32-hppa.c: (elf32_hppa_backend_fake_sections): The stab
- string table should have sh_type == SHT_STRTAB. Add
- processing to make it so.
-
- * elfcode.h: (bfd_section_from_shdr): String tables (other
- than .strtab) were not getting the file offsets recorded, so
- they could not be read from disk.
-
- * elfcode.h: (elf_make_sections): Leave the sh_addr field of
- the section header and the vma field of a section at 0 if the
- section is not part of the program execution image. (e.g.,
- .stab)

- Include a.out for both HOST_HPPAHPUX and HOST_HPPABSD. Delete
- forward structure declarations, they are unnecessary.

- Change "symbols" to "symtab". Add "stringtab" and "reloc_filepos"
- fields for future use. Change obj_som_* macros as appropriate.
- (som_section_data): New structure to keep SOM specific information
- about BFD sections (for future use).
-
- * som.c: Provide PARAMS declarations for all functions currently
- in this file.
- (struct container): Delete unwanted structure definition.
- (som_object_setup): Add comments. Use som_mkobject to allocate
- SOM specific information in the BFD; use information from the
- file and (possibly empty) auxiliary headers to initialize this
- information. Delete redundant bfd_get_symcount (abfd) "calls".
- (setup_sections): Return type is now boolean, fix return statements.
- "Fix" handling of BSS like subspaces in the computation of the
- containing space's size. If the subspace has relocations, set the
- appropriate BFD section flags and record the index into and the
- size of the fixup stream. Always return a value.
- (som_object_p): Set bfd_error appropriately if errors are detected
- from bfd_{read,seek} functions. Handle EXECLIBMAGIC type files.
- Do not try to read a non-existant auxiliary header.
- (som_mkobject): Flesh out.
- (som_section_hook): Allocate space to hold SOM specific information
- about sections.

-
-Fri Dec 6 22:58:48 1991 K. Richard Pixley (rich at rtl.cygnus.com)
-
- * Makefile.in: install using INSTALL_DATA, added standards.text
- support.
-
- * configure.in: mark directory as target dependent. configure

- against ${srcdir}.
-
-Thu Dec 5 22:46:19 1991 K. Richard Pixley (rich at rtl.cygnus.com)
-
- * Makefile.in: idestdir and ddestdir go away. Added copyrights

- and mandir now keyed off datadir by default.
-
-Wed Dec 4 10:14:17 1991 Steve Chamberlain (sac at rtl.cygnus.com)
-
- * aoutf1.h (sunos_<size>_object_p, sunos4_callback): moved the
- computation of arch and machine type so it's worked out before
- some_aout_object_p is called.
- * aoutx.h: (some_aout_object_p): don't set arch and mach to
- unknown.
- * archures.c: add extra field 'section_align_power' to hold
- default section alignment in object files.
- * cpu-a29k.c, cpu-h8300.c, cpu-i386.c, cpu-i960.c, cpu-m68k.c,
- cpu-m88k.c, cpu-mips.c, cpu-rs6000.c, cpu-sparc.c, cpu-vax.c:

-
-Wed Dec 4 02:00:30 1991 John Gilmore (gnu at cygnus.com)
-
- * bfd.c (bfd_get_mtime): Don't cache mtime any more; only

-
-Tue Dec 3 22:54:50 1991 John Gilmore (gnu at cygnus.com)
-
- * targets.c: Revise comments about how to configure the target
- vector, to match reality. Remove mention of obsolete methods.
- Remove long lists of capitalized macros that turn into the same
- thing in lowercase. Normal vector simply lists all known
- lowercase xvec names; all other cases are handled by SELECT_VECS.
-
- * config/mt-i386-coff: Set DEFAULT_VECTOR to real identifier,
- not macro name.
-
- * config/mt-i960-{coff,bout}: Use SELECT_VECS to make a short
- list of supported targets.
-
-Tue Dec 3 14:06:15 1991 Per Bothner (bothner at cygnus.com)
-
- * archive.c (bsd_write_armap): The pad byte sometimes added to
- the string table in a __.SYMDEF member is now
- counted as part of the size of the string table.
- This is compatible with the old ranlib, as well as Sun's.
-
-Tue Dec 3 10:53:30 1991 Steve Chamberlain (sac at rtl.cygnus.com)
-
- * srec.c: Rewrote to fix many bugs; now gets the record type
- right, doesn't choke on input, sets the start address in an S9 and
- fills in the filename on an S0.
-

- if the entry point is contained in the text segment, even if the
- text segment is at location 0.
-
- * coff-mips.c, coffcode.h: Peter Schauer's patch to kludge in
- nonstandard MIPS sections (.rdata, .sdata, etc).

-
- * stab-syms.c, syms.c: Moved bfd_stab_name() and bfd_stab_names[]
- from syms.c to new file stab-syms.c. Also, since GNU extended
- type codes such as N_SETT are no longer in ../include/stab.def,

-Thu Nov 21 11:50:49 1991 John Gilmore (gnu at cygnus.com)
-
- * libaout.h (WORK_OUT_FILE_POSITIONS): One more try at this

- * aoutx.h: Fix comments to match.
-
-Tue Nov 19 18:49:01 1991 Per Bothner (bothner at cygnus.com)
-
- * libaout.h (WORK_OUT_FILE_POSITIONS): Use new LOGICAL_TXTADDR,
- LOGICAL_TXTOFF, LOGICAL_TXTSIZE macros to figure out numbers
- for the "logical" text segment (i.e. never consider the exec
- header to be part of the text segment). This change is
- needed for consistency with various other parts of bfd and ld.
- * aoutx.h (NAME(aout,soe_aout_object_p)): Fix comment,
- and move calculation of obj_textsec(abfd)->size to libaout.h.
- * bfd-in.h: Removed bogus ';'.
-
- * Makefile.in: Add MINIMIZE flag to select lean
- or bloated target_vector.
- * targets.c: Use new MINIMIZE macro, and add trad_core if needed.
- * newsos3.c: Fixes to ../include/aout64.h remove need
- for special N_TXTOFF macro, but require N_HEADER_IN_TEXT.
-
-Mon Nov 18 12:00:59 1991 Per Bothner (bothner at cygnus.com)
-
- * aout-target.h, aoutf1.h, newsos3.c: Make aout-target.h

-
-Sun Nov 17 13:29:39 1991 Per Bothner (bothner at cygnus.com)
-
- * targets.c: Make the default target_vector contain
- just &DEFAULT_VECTOR. This makes executables a lot smaller.
- Old behavior can be gotten by defining ALL_TARGETS.
- * aoutf1.h, demo64.c, i386aout.c, newsos3.c, sunos.c:
- Factored out common code into new file aout-target.h.
- Saves a lot of duplicate code for a.out variants.
-
-Fri Nov 15 13:00:43 1991 Per Bothner (bothner at cygnus.com)

- * elf.c: Add minimal support for ELF symbol tables. Generates
- canonical bfd symbol tables from ELF symbol tables. Change the
- name of some functions from bfd_<name> to elf_<name>.
-
- * syms.c: Trivial fix to comment to remove a redundant "to".
-
-Wed Nov 13 17:02:01 1991 John Gilmore (gnu at cygnus.com)
-
- * coff-{i386,m68k,m88k}.c: Change name of file format to standard

-
-Mon Nov 11 18:36:47 1991 Per Bothner (bothner at cygnus.com)
-
- * aoutx.h (NAME(aout,find_nearest_line)): Handle the case

- to the way it was.
-
-Thu Nov 7 11:03:55 1991 Steve Chamberlain (sac at rtl.cygnus.com)
-
- * coffcode.h: Defined new macros [PUT|GET]LINENO_LNNO for
- manipulation of lnno fields in lineno structs in a coff-<f>.h
- independent way. Override it in coff-<f>.h to your favourite
- number if you don't have a 16bit lnno field. (coff_swap_lineno_in)
- (coff_swap_lineno_out): modified to use the new macros.
-
-Mon Nov 4 11:38:33 1991 Steve Chamberlain (sac at cygnus.com)
-
- * aoutf1.h (sunos4_callback): Now defaults to 68020 rather than
- unknown arch when the magic number doesn't specify the
- architecture, since some OSs (eg old sun3s) don't set the number, and
- 020 is probably the right answer anyway.
-
-Sun Nov 3 12:07:08 1991 Per Bothner (bothner at cygnus.com)
-
- * hosts/h-news.h, hosts/h-rtbsd.h:
- Get rid of MISSING_VFPRINTF, since libiberty provides one.

- (coff_compute_file_section_positions): now works out the section
- alignment and size correctly in all cases.
- (coff_get_symtab): looks for constructor symbols and calls the
- right function when they're found. (coff_canonicalize_reloc):
- knows when a section is full of constructors and does the right
- thing.
- * cpu-m88k.c: Added default_reloc_type lookup to the architecture
- description.
- * libbfd-in.h: (bfd_default_reloc_type_lookup) defun added.

- arch independent constructor relocation type.
- (bfd_reloc_type_lookup): removed the comment "this will go away"
- since it won't. (bfd_howto_32): stolen from 88k, this is a 32bit
- reloc which is used when BFD_RELOC_CTOR falls through to give a
- default 32bit reloc for constructors.
- (bfd_default_reloc_type_lookup): added.
- * aoutf1.h: fixed SEGMENT_SIZE typo.
-
-Thu Oct 31 18:23:06 1991 John Gilmore (gnu at cygnus.com)
-
- * coff-rs6000.c: Change name to "aixcoff-rs6000", to avoid

-
-Thu Oct 24 02:03:24 1991 Fred Fish (fnf at cygnus.com)

-
-Mon Oct 21 17:48:48 1991 John Gilmore (gnu at cygnus.com)
-
- * hosts/h-vaxult.h: Remove malloc/free decls covered in stdlib.h.
- Fix HOST_PAGE_SIZE and HOST_SEGMENT_SIZE. From David Taylor.
-
-Mon Oct 21 09:34:11 1991 Steve Chamberlain (steve at rtl.cygnus.com)
-
- * coffcode.h (coff_compute_section_file_positions): make it pad
- section size out if there are alignment restrictions so that the
- image will be ok on a system where section positions are worked
- out by accumulating sizes rather than from the section headers.
- * targets.c (proto write_armap). Changed orl_count to unsigned.
- * opncls.c (bfd_close_all_done). Added so that generative
- programs like gas can close a bfd without causing bfd confusion.
- * libbfd.h (changed becuase of protos)
- * amdcoff.c: messed with the way that jmp displacements are
- calcualated. This may not yet be totally correct.
- * archive.c (coff_write_armap): rewrote the way that ranlibs are
- written out.
- * coffcode.h (fixup_symbol_value): now doesn't core dump if a non
- abs symbol has no section (like a register symbol).

- with sensitive applications.
- * libbfd.c (bfd_write_bigendian_4byte_int): added.
-
-Wed Oct 16 22:58:45 1991 John Gilmore (gnu at cygnus.com)

-
-Wed Oct 16 12:43:49 1991 Per Bothner (bothner at cygnus.com)
-
- * archive.c (bsd_write_argmap): The size of the ranlib structures
- should not include the size field itself.
- * aoutx.h, libaout.h (NAME(aout, sizeof_headers)): Use
- adata(abfd)->exec_bytes_size field instead of constant macro,
- because aoutx.h compiles to a simple .o file shared by
- all 32-bits a.out targets.
-
-Wed Oct 16 11:11:05 1991 John Gilmore (gnu at cygnus.com)

- * bout.c: Remove unused i960_align; lint dummy core file handlers.
- * cpu-h8300.c: lint.
-
- * host-aout.c: New strategy. We use common code, include files,
- and data structures to handle the file, but set a few parameters
- from the host's config file (page size, text start addr, etc).
- * libaout.h: Define HP BSD machine types.
- * aoutf1.h: Handle reading a.outs with these types.
-
- * trad-core.c: Pass the u.u_ar0 value as the negative of the
- virtual-memory-address of the .reg section. We can't just make a
- section for "all the regs and nothing else" because only GDB knows
- exactly where the regs are (scattered around the upage and stack).
- Clean up memory allocation. Remove big- and little-endian
- vectors, replace with single vector; this only runs on the host,
- in host byte order. Replace byteswap routines with aborts in case
- anyone calls them.
- * targets.c: There's only one trad_core_vec now.
- * aoutf1.h (sunos_core_file_p): VMA of .reg* now needs to be 0.

-
- * hosts/h-amix.h (free): Fix prototype.
-

- segment_size and exec_bytes_size. These help generic code
- (in aoutx.h and libaout.h) to figure out where to align
- the various segments in a demand paged file.
- * libaout.h (WRITE_HEADER): Use new (struct aoutdata) fields
- to decide if the exec header counts in a_text (text segment size).
- Also, assume D_PAGED flag is set; don't set it here.
- * bout.c (b_out_callback): Add initialization of
- adata fields page_size, segment_size, and exec_bytes_size.
- * host-aout.c (NAME(host_aout, callback) and
- NAME(host_aout,mkobject): Ditto.
- * i386aout.c (aout386_callback) and new aout386_mkobject): Ditto.
- * newos3.c (newsos3_callback) and new newsos_mkobject): Ditto.
- * aoutf1.c (sunos4_callback) and new sunos_mkobject): Ditto.
- * aoutx.h (NAME(aout,some_aout_object_p)): Don't subtract
- EXEC_BYTES_SIZE from the a_test size; this is only appropriate
- for some systems (mainly sunos), so do it in the callback instead.
- Same routine: Add stuff to the THIS_IS_ONLY_DOCUMENTATION comment.
- * aoutx.h (NAME(aout,set_section_contents): Change the way
- filepos and size of sections are carried out to support
- older styles of demand paged executables.
-

- to new prototypes
- * targets.c: Added new entry points for coff swapping
-
-Fri Oct 11 03:01:52 1991 John Gilmore (gnu at cygnus.com)
-
- Restructure configuration scheme for bfd, binutils, ld.
-
- * include/sys/h-*.h: Move to bfd/hosts/h-*.h.
- * configure.in: Revise to symlink sysdep.h to hosts/h-xxx.h.
- Change some config names to match other dirs.
- * *.c: Include bfd.h before sysdep.h, so ansidecl and PROTO()
- get defined first.
- * Makefile.in: Use -I. to get sysdep.h. Remove refs to
- ../include/sysdep.h.
- * cpu-i960.c: Strncmp needed a length arg.

-
-Thu Oct 10 17:54:08 1991 John Gilmore (gnu at cygnus.com)
-
- * config/*: trad-core support is HOST dependent, not target
- dependent. Target config files only set DEFAULT_VECTOR and/or
- other vector elements. Exception: when host-aout.c is in use,
- in which case we're forced to assume we're native (hp, vax,
- tahoe). Rename XDEPFILES to HDEPFILES.
- * Makefile.in: Rename XDEPFILES.
- * config/h-sun*: Don't force static linking.
- * trad-core.c: Document how to use it nowadays.
- * i386aout.c, newsos3.c: Clean up.
- * i386coff.c: Allow 386 coff files to be used as core files too
- (for reading core files from embedded systems).

-
- * Add i386aout.c for a.out support on the i386.
-
-Tue Oct 8 12:18:54 1991 Roland H. Pesch (pesch at cygnus.com)
-
- * reloc.c, section.c, syms.c, targets.c: correct info-node
- structure in *doc* comments.
- doc/Makefile: stop hiding complaints from makeinfo.
-
-Sun Oct 6 19:10:06 1991 John Gilmore (gnu at cygnus.com)
-
- * aoutx.h (...some_aout_object_p): Take a third parameter,
- the internal_exec struct, and avoid ever looking at an
- external_exec. All callers changed to read the entire
- external_exec struct, swap and check its magic number,
- swap in the whole structure, and pass the swapped-in version to
- some_aout_object_p.
- * bout.c: Bring into modern era. Use single _object_p routine
- for big- aand little-endian. Provide internal and external
- exec header structs. Use separate swap-in and swap-out routines.
-
- * libaout.h: Move struct internal_exec from ../include/aout64.h
- to here. Add obj_symbol_entry_size to struct aoutdata.
- * aoutx.h (...some_aout_object_p): Set obj_symbol_entry_size.
-
- * ../include/aout64.h: Change EXTERNAL_LIST_SIZE to

-
- * archures.c: Rename `struct bfd_arch_info_struct' to `struct
- bfd_arch_info'. Rename `typedef bfd_arch_info_struct_type' to
- `bfd_arch_info_type'. All uses changed.
- * reloc.c: Rename `bfd_reloc_status_enum_type' to
- `bfd_reloc_status_type'. Rename `bfd_reloc_code_enum_real_type'
- to `bfd_reloc_code_real_type'. (This seems to be a misnomer,
- it needs a better name.) All uses changed.
- * targets.c: Rename `enum target_flavour_enum' to `enum
- target_flavour', and remove the `_enum' from all of the enum
- values themselves. All uses changed.
-
- * configure.in, config/h-i386mach: i386 mach host.
- * config/t-i386-aout: Use host-aout.c.
-
- * trad-core.c: Give it its own xvec's to make it independent
- of other file formats.

-
-Thu Oct 3 19:39:55 1991 John Gilmore (gnu at cygnus.com)
-
- * bfd-in.h: enum boolean => enum bfd_boolean for SVR4. Gumby's
- prediction is vindicated!
-
- * bfd-in.h, libbfd-in.h, doc/Makefile, doc/tolibbfd, doc/intobfd:
- Remove refs to howto.c, since Steve forgot.
-
-Thu Oct 3 07:49:21 1991 Steve Chamberlain (steve at cygnus.com)
-
- * elf.c: took the abort out of set_arch_mach so that objdump -i will
- still work. Now allows any architecture/machine to be set.
-
-Wed Oct 2 13:50:35 1991 Steve Chamberlain (steve at cygnus.com)
-
- * howto.c deleted and moved code to reloc.c
-
- * libbfd.h, libbfd-in.h removed $id stuff for real
-
- * cpu-h8300.c Made it match various different spellings of h8300.
-
- * archures.c: Took out the first char filter which made it only
- look for a cpu/arch match when the first chars of supplied and
- tested names were the same.
-
- * targets.c removed oasys stuff, pending someone to fix the bugs
- in it.
-
-
-Tue Oct 1 12:29:44 1991 John Gilmore (gnu at cygnus.com)
-
- * Makefile.in, configure.in, targets.c, elf.c: Add preliminary
- ELF support good enough for GDB.

- * config/t-m68k-coff, t-m88k-coff, t-m88k-aout: Make files nonempty
- so `diff' and `patch' can cope.
-
-Tue Oct 1 11:24:31 1991 Steve Chamberlain (steve at cygnus.com)
-
- * archures.c: removed texinfo error
-
- * init.c: added texinfo hooks, and removed initialization error
- message.
-
- * libcoff-in.h, libbfd-in.h removed $id field so cvs can merge
- without complaints.
-
-Tue Oct 1 05:02:53 1991 John Gilmore (gnu at cygnus.com)
-
- * cpu-i960.c: Avoid numerical count of initializers.
-
- Vax Ultrix changes from David Taylor <taylor@think.com>:

-
-Mon Sep 30 15:13:46 1991 Steve Chamberlain (steve at cygnus.com)
-
- * bfd-in.h VERSION, change version number to 0.18, this makes a
- gap, but now is the same as the linker version number.
-
- * cpu-a29k.c, cpu-i386.c, cpu-m68k.c, cpu-mips.c, cpu-vax.c,
- cpu-h8300.c, cpu-i960.c, cpu-m88k.c, cpu-sparc.c: added. These
- files will eventually contain processor specific bits for bfd,
- like strange relocation information and dis/assembly. So far only
- the H8 has been even partially done. This work also ties in with
- the change in handling architectures.
-
- * amdcoff.c: (a29k_reloc) fix error message.
-
- * aout-f1.h: (choose_reloc_size) now calls bfd_get_arch to
- discover the architecture of the bfd. (sunos4_callback) calls the
- function bfd_set_arch_mach rather than stuffing stuff directly
- into the bfd. (sunos4_write_object_contents), changed names of
- accessor functions.
-
- * aoutx.h: (set_arch_mach) now calls bfd_default_set_arch_mach to
- setup the environment.
-
- * archive.c: (bfd_slurp_coff_armap) coff archives always have the
- headers in big endian format, regardless of the endianess of the
- host or target.
-
- * archures.c: totally changed. Now an architecture is represented
- with a pointer to an info structure rather than an enumerated type
- and a long. The old info is available as two elements in the
- structure. Future enhancements to architecure support will
- involve pointers to methods being placed into the info structure.
-
- * bfd.c: changed the definition of the bfd structure for the new
- architecture stuff.
-
- * bout.c: (b_out_set_arch_mach) changed to use the new
- architecture mechanism.
-
- * coffcode.h: (coff_set_arch_mach, coff_set_flags) changed to use
- the new architecture mechanism.
-
- * configure.in: added h8 stuff.
-
- * ieee.c: too many changes to note. Now ieee files written with
- bfd gas and ld can be read by gld and ieee only linkers and
- simulators.
-
- * libbfd.c, libbfd.h: changed prototype of bfd_write.
-
- * newsos3.c: (newos3_callback) now calls bfd_set_arch_mach rather
- than fixing the structure directly.
-
- * oasys.c: (oasys_object_p) now calls bfd_default_set_arch_mach rather
- than fixing the structure directly.
-
- * opncls.c: (new_bfd) makes sure that bfd_init has been called
- before opening a bfd.
-
- * srec.c: (srec_set_arch_mach) now calls bfd_default_set_arch_mach
- rather than fixing the structure directly.
-
- * targets.c: (target_vector) now by defining SELECT_VECS (perhaps
- in the t/hmake file) a user can select which backends they want
- linked with bfd without changing the source.
-
- * init.c: new, looks after initializing modules.
-
- * howto.c: for future use, will allow an application to work out
- what cookie to use as a handle on a relcoatio howto.
-
-Mon Sep 30 13:31:15 1991 John Gilmore (gnu at cygnus.com)
-
- * srec.c: Better error checking, partly from Peter Schauer.
- (srec_object_p): Avoid assuming any file that starts with 'S' is
- an S-record file! (Check for 3 uppercase-hex digits after it.)
- (ISHEX): Define new macro for checking supposedly hex characters.
- (pass_over): Treat as EOF any S-record line that:
- * doesn't have hex in either size character
- * produces a size larger than 0x7F
- * has an unrecognized type number
-
-Thu Sep 26 15:27:29 1991 John Gilmore (gnu at cygnus.com)
-
- * aoutf1.h, aoutx.h, bout.c, coffcode.h, host-aout.c, oasys.c,
- opncls.c: Lint (saber actually).

- (coff_swap_aux_{in,out}): Check that FILNMLEN == E_FILNMLEN
- and DIMNUM == E_DIMNUM.
- * configure.in: Handle a29k-*-* hosts, and targets
- a29k-*-coff, a29k-*-aout, and a29k-*-sym1.
- * libcoff-in.h: Add local_n_btmask, local_n_btshft,

- * bfd.texinfo: generalize most references to linker
-
-Tue Aug 20 15:18:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
-
- * Makefile.in: include core.p in PROTOS (building better bfd.h)

-
-Fri Jun 14 13:19:40 1991 Steve Chamberlain (steve at cygint.cygnus.com)
-
- * ../include/bfd.h (struct bfd_target): Added new field
- "align_power_min" which contains the minimum alignment for a

-
- Changed all the [get|put][name] routines to use [get|put]_[size
- in bytes].
-

-
- * sunos.c: (choose_reloc_size) added: (sunos4_callback) calls
- choose_reloc_size. (sunos4_write_object_contents) now calls

- size of the sections correctly.
-
-
-
-Fri May 10 16:58:53 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- Merge Per Bothner's changes to modularize BFD a.out a bit.
-
- * libbfd.h, libbfd.c (bfd_generic_get_section_contents): Add.
- * ieee.c: Cast enums to int before comparing them, for brain-
- dead compilers.
- * coff-code.h: Remove coff_get_section_contents, and use the
- generic one instead.
-
- * aout.c: Derive new module from sunos.c, containing generic
- support code for all kinds of a.out files.
-
- * sunos.c: Remove all code that goes in aout.c. Split out
- machine dependent followup in sunos4_object_p into
- sunos4_callback. Use JUMP_TABLE(aout) for the transver vector,
- and redefine only the names we CHANGE, not all the names. Drop
- the little-endian vector, and rename the vector as sunos4 rather
- than generic.
-
- * b.out.c: Use aout.c routines for most of the work. Slight
- changes for the new regime. Remove close_and_cleanup and
- get_section_contents in favor of generics. New transfer vector
- regime.
-
- * newsos.c: New support for Sony NEWS, another a.out format.
-
- * ecoff.c: Remove close_and_cleanup. New tvec regime.
- * icoff.c, m88k-bcs.c: Add write_contents to tvec.
- * ieee.c, oasys.c: Remove close_and_cleanup, add write_contents
- to tvec.
- * opncls.c (bfd_close): Call format-dependent write_contents
- routine, if writing, before calling target-dependent
- close_and_cleanup routine (which is now always generic, I think).
- * srec.c: Use bfd_alloc instead of malloc. Remove
- close_and_cleanup and move code from it to
- srec_write_object_contents. Add write_contents to tvec.
- * targets.c: Remove a.out little vector, replace a.out big
- vector with SunOS vector. FIXME: Need Vax support again now.
-
- * libbfd.h: Add write_contents format-dependent-vector to the
- bfd_target vector. Supply a generic close_and_cleanup routine.
- * liba.out.h: Handle the new aout.c split. Add prototypes for
- all routines defined in aout.c. Rename "sunos" things to "aout"
- things. Add a few fields where needed for various formats.
- * Makefile.in: Add aout.c and newsos.c.
-
- * archive.c, ieee.c, oasys.c: Lint.
-
-Fri May 10 12:34:48 1991 Steve Chamberlain (steve at cygint.cygnus.com)
-
- * ../include/bfd.h
- changed forward declaration struct stat; to reduce warnings. Changed
- comment on bfd_h_<x>_x.
-
- * ../include/m68kcoff.h, ../include/intel-coff.h,
- ../include/m88k-bcs.h
- Now there are two incarnations of relocs, linenos and syments. One for
- internal digestion, and one full of char arrays for I/O. The original
- names have gone to detect errors.
-
- * Makefile.in, m68kcoff.c, targets.c
- Test new structure code with a 68k coff implementaion
-
- * coff-code.h, icoff.c, coffswap.c, libcoff.h
- Fixed all the places where there were problems with the size and
- alignments of structures on disk and structures in memory. #ifed out
- all the code in coffswap.c, since it should be done using the target
- swap routines now.
-
-Thu May 9 11:00:45 1991 Steve Chamberlain (steve at cygint.cygnus.com)
-
- * ieee.c (do_one, ieee_slurp_section_data): now supports the load
- multiple reloc command.
-
- * sunos.c (sunos4_set_section_contents): Made it so that sections
- are always padded to their alignment size.
-
-Sat May 4 15:49:43 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * archive.c, bfd.c, coff-code.h, opncls.c, sunos.c, trad-core.c:
- Clean up types and such (saber C problems).
- * ecoff.c: Clean up types and such. Remove routines that are
- not used. Fix up reading and swapping of shorts from files.
-
- Notes on bfd-0.5.2-patch1a, from Per Bothner:
-
- * a.out.vax.c: Remove two bogus "static" from prototypes.
-
- * ecoff.c: Got rid of lots of non-working junk (that had
- been copied directly from coff-code.h).
- Updated to be consistent with updates to icoff.c and coff-code.h.
-
- * libbfd.h: Added definitions for S_IXUSR, S_IXGRP, and S_IXOTH
- if they're missing (as they are in (BDS-4.3-based) NewsOS-3).
-
- * sunos.c (n_txtoff): (Re-)Add support for sony. This is a kludge,
- but until the target_vector is automatically generated,
- it's as good as any. Note that the text offset is the only
- difference between NewsOS and SunOs (including magic numbers).
- (Most of the sunos_* routines should to renamed bsd_*
- and move to a bsd.c file. Then (and when the target_vector
- is automatically generated) it might make sense to create
- a separate Sony target.)
-
- * sysdep.h: Don't declare fread and fwrite. Causes trouble
- on some systems, and doesn't help on others.
- Similarly, only define X_OK if not already defined.
-
- * trad-core.c: Don't include sys/stat.h - at least
- on NewsOS 3, it has already been included.
-
-Tue Mar 5 01:47:57 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * coff-code.h (bfd_coff_swap_sym, bfd_coff_swap_aux,
- bfd_coff_swap_lineno): Export the routines that byte-swap COFF
- symbol tables if necessary when reading them in, so gdb can use
- them. Add "bfd_coff_" to the names so they won't conflict with
- names in calling programs. FIXME-soon: if coff-code.h is
- included in two BFD modules, this will cause duplicate
- definitions; the routines should be exported to a separate,
- common, module (probably along with a mess of other ones).
-
-Sat Mar 2 12:11:26 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- Improve modtime support.
-
- * bfd.h: Add boolean mtime_set, and declare bfd_get_mtime.
- Remove #define for bfd_get_mtime. Remove gratuitous comment.
- * bfd.c (bfd_get_mtime): New fn, caches mtime, gets if not cached.
- BUG: archive members still do not get correct mod times.
-
- Improve floating point support for core files.
-
- * sunos.c (struct core): Change void *fpa_dummy to double fp_stuff.
- (sunos4_core_file_p): Create a second registers section in the
- core file, called ".reg2", for the float registers.
-
-Thu Feb 14 15:49:06 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
-
- * many changes to improve archive handling; found a logic flaw in
- bfd_check_format which only just happened to work by cooncidence.
-
-Thu Feb 14 07:53:16 1991 Steve Chamberlain (steve at cygint.cygnus.com)
-
- * bfd.c (bfd_perform_relocation): fixed to use output_offsets
- correctly.
-
- * bfd.h: changed type of udata in asymbol to void *, like it
- should be. Added bfd_reloc_dangerous enum member.
-
- * coff-code.h: Fixed it so that internally generated symbols get
- their values relocated correctly in all cases. Removed calls to
- xmalloc.
-
- * icoff.c: Not understanding the destination symbol of a reloc is
- not a failure any more, just 'dangerous'. This allows linking of
- b.out and coff images.
-
- * sunos.c: Cleaned up the way that ZMAGIC section sizes are
- calculated.
-
-
-Tue Feb 12 13:25:46 1991 Steve Chamberlain (steve at cygint.cygnus.com)
-
- * sunos.c (translate_to_native_sym_flags): fixed
- sym_pointer->n_value so that symbols on the way out get their
- section relative values calculated correctly.
-
- * coff-code.h (mangle_symbols): fixed problem where tags were not
- being relocated for structs, enums, unions. Also various lints.
-
-Mon Feb 11 19:52:26 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
-
- * archive.c (get_elt_at_filepos): system_call_error returned
- incorrectly.
-
-Sun Feb 10 23:18:40 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
-
- * Resolve the use of no_error and system_call_error.
- The bfd library itself now will never set bfd_error to
- no_error.
-
- The code still needs to be combed to make sure all the error
- codes are correct. I suspect they are not always set correctly.
-
- * The names of all the messages have _ prepended because the sun
- bundled compiler can't distinguish from a macro which takes an
- argument and the same identifier in a non-macro context.
-
- * The reason for the above being that entry points which used to
- be trampoline functions are now just macros which expand to a
- direct call through the bfd's xfer vector.
-
- * (../include/intel-coff.h) F_AR32WR: fix this constant. Why
- must gas have its own version of everything (the gas version
- had the correct value)
-
-Tue Feb 5 11:46:53 1991 Steve Chamberlain (steve at cygint.cygnus.com)
-
- * b.out.c: Added patches supplied by chrisb@mipon2.intel.com to
- properly support i960 architecture and output correct reloc stuff.
-
- * bfd.h: added prototype for bfd_printable_arch_mach, added
- BFD_FAIL
-
- * coff-code.h: Applied patches from chrisb to support i960
- architecture, zero relocs and swap them correcly and conditionally
- compiled the timestamp.
-
- * sunos.c: Made the default section alignment 2^3 so that doubles
- are done properly. Fixed the same reloc bug that was in b.out.c
-
- * sysdep.h: Now compiles on a Posix box
-
-Wed Jan 30 21:36:26 1991 John Gilmore (gnu at cygint.cygnus.com)
-
- * icoff.c: Fix comment on big-endian version.
- * coff-code.h: Make HAS_RELOC really work (it's backwards from
- F_RELFLG). Set F_AR32WR in output files if little endian
- architecture.
-
-Tue Jan 29 20:56:10 PST 1991 steve@cygnus.com
-
- * archures.c fixed =/== typo

- order
-
- * libbfd.h fixed includes
-
-
-Mon Jan 21 11:53:51 PST 1991 steve@cygnus.com
-
- * bfd.h changed name of alignment entry in sec_struct to
- alignment_power, because of conflicting uses within bfd.
- Now it should be obvious that it's a 2**n alignment
- specifier. Removed start_pad, end_alignment, block, minsize,
- output_file_alignment, subsection_alignment and original_vma fields.
- Added align_power() macro. Fixed bfd_section_alignment

- conversion between alignment types. (coff_symbol_from)
- added. (coff_count_linenumbers) only counts linenumbers
- if symbol is of coff-type. (coff_mangle_symbols) only
- heavily mangles symbols if symbol is coff-type.
- (coff_write_symbols) various lints. (coff_write_object_contents)
- various lints and modification for alignment conversion.

- pointer lint. Added support for callj relocation. Fixed bug where
- the last 32 bytes of the text section were overwritten by data. Fixed bug
- where archives of b.out didn't work due bfd_slurp_extended_name_table
- returning false.

- This is so callers can avoid <stdlib.h> which doesn't exist
- on older systems.
-
- * bfd.c (map_over_sections): Add debugging code, since I

- and buf.
-
- * cisco-core.c (cisco_core_file_p): Only pass one argument to
- bfd_zmalloc. Free a pointer, not a union.
- (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
-
-Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
-
- * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
-
- * som.c (bfd_section_from_som_symbol): Only to do the value
- comparison for function symbols within executables.
-
- * som.c (bfd_section_from_som_symbol): Renamed from
- som_section_from_subspace_index. Pass in a native SOM symbol.
- For executables, iterate through the sections to find out
- which contains the symbol's address rather than using the
- symbol_info field. (symbol_info has a different meaning for
- dynamicly linked executables.)
-
- * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
- bfd_zmalloc.
-
- * som.c (som_begin_writing): Fix braino (one call to align
- space/subspace data was done unconditionally rather than
- just for executables.)
-
- * som.c (som_begin_writing): Align text in all executables to
- make HPUX kernel happy. Fixes strip/objcopy for shared
- executables.
-
-Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
-
- * som.c (som_begin_writing): Account for alignment needs of
- subspaces too when writing executables. Never request a negative
- bss size. Fixes some problems with demand paged executables,
- still having problems with pure executables and shared executables.
-
-Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
-

- containing all the private section information which needs
- to be copied from input section to output section during

- subspace dictionaries be pointers (to save space when
- only reading objects).

- that we really need to make objcopy and strip work. Allocate
- the copy_data structure for the output bfd before copying.
-
- * som.h (struct som_exec_data): New structure to hold exec
- info that must be preserved when running objcopy/strip.
- (struct somdata): Add new "exec_data" field and accessor
- macro. Add some comments on how the various fields are used.
- (som_section_data_struct): Make is_space and is_subspace bitfields.
- Delete unused subspace_index. All references now use the
- target_index field within the section structure itself.
-
- * som.c (make_unique_section): Delete unused declaration.
- (som_bfd_copy_private_bfd_data): New function.
- (som_object_setup): Allocate space for and save exec information
- that needs to be copied during objcopy/strip.
- (som_mkobject): Do not allocate space for a file header here.
- It is not used when only reading SOM objects.
- (som_prep_headers): Allocate space for and attach a file header
- to the output bfd. For executables, use the saved system_id
- value rather than trying to guess the right value. Do not abort
- wwhen setting file_hdr->entry* for executables.
- (som_begin_writing): For executables, set the exec_entry and
- exec_flags fields.
- (som_copy_private_backend_section_data): Always return a value.
-
- * libhppa.h (PA_PAGESIZE): Define.
-
- * som.c (SOM_ALIGN): Define.
- (som_begin_writing): If writing an executable, initialize all
- fields in the exec header to zero. Update fields in the exec
- header as sizes of loadable subspaces are computed. Carefully
- preserve alignments when building executables. Actually write the
- exec after all the fields are filled in.
-
- * Better long-filename handling. Reads SOM ABI compliant extended
- names, but doesn't quite write compliant extended names yet.
- * som.c (som_slurp_extended_name_table): Delete function. The
- generic code will handle things correctly.
- (som_slurp_armap): Seek to the beginning of the next member.
- (normalize): New function.
- (som_bfd_ar_write_symbol_stuff): Take the size of the extended

- elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
- returns NULL, it is not an error. It's possible that some of
- these checks are not necessary (because the size can never be
- zero), but putting in the checks is the conservative thing to do
- in light of the fact that some of these malloc calls replaced
- unchecked alloca calls, in which a zero argument would work fine.
-
-Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
-
- * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
- duplicate definition.
- (osf_core_bfd_is_local_label): Define.
-
- * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail

- failure indication, it merely means there are no relocs.
-
- * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
- after NAME, since SunOS /bin/cc can't handle it.
-
-Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
-
- * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.

-
-Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
-
- * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
- all that convoluted stuff with NAME, CAT3, etc. The convoluted
- stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
-
-Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
-
- * som.c (som_prep_for_fixups): Detect section symbols based

- (som_begin_writing): Leave space for an exec header if writing
- an executable.
- (som_slurp_symbol_table): Recognize both forms of section symbol
- names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"

-
- * som.c (som_prep_for_fixups): A relocation involving the section
- symbol for the *ABS* section is really a relocation involving

- * libbfd-in.h: Remove alloca cruft. It was missing some necessary
- cruft (like the #pragma alloca for AIX).

-
-Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
-

-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>"

-BFD is a an object file library. It permits applications to use the
-same routines to process object files regardless of their format.
-
-BFD is used by the GNU debugger, assembler, linker, and the binary
-utilities.
-
-The documentation on using BFD is scanty and may be occasionally
-incorrect. Pointers to documentation problems, or an entirely
-rewritten manual, would be appreciated.
-
-There is some BFD internals documentation in doc/bfdint.texi which may
-help programmers who want to modify BFD.
-
-BFD is normally built as part of another package. See the build
-instructions for that package, probably in a README file in the
-appropriate directory.
-
-BFD supports the following configure options:
-
- --target=TARGET
- The default target for which to build the library. TARGET is
- a configuration target triplet, such as sparc-sun-solaris.
- --enable-targets=TARGET,TARGET,TARGET...
- Additional targets the library should support. To include
- support for all known targets, use --enable-targets=all.
- --enable-64-bit-bfd
- Include support for 64 bit targets. This is automatically
- turned on if you explicitly request a 64 bit target, but not
- for --enable-targets=all. This requires a compiler with a 64
- bit integer type, such as gcc.
- --enable-shared
- Build BFD as a shared library.
- --with-mmap
- Use mmap when accessing files. This is faster on some hosts,
- but slower on others. It may not work on all hosts.
-
-Report bugs with BFD to bug-gnu-utils@gnu.org.
-
-Patches are encouraged. When sending patches, always send the output
-of diff -u or diff -c from the original file to the new file. Do not
-send default diff output. Do not make the diff from the new file to
-the original file. Remember that any patch must not break other
-systems. Remember that BFD must support cross compilation from any
-host to any target, so patches which use ``#ifdef HOST'' are not
-acceptable. Please also read the ``Reporting Bugs'' section of the
-gcc manual.
-
-Bug reports without patches will be remembered, but they may never get
-fixed until somebody volunteers to fix them.

-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 unneeded 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.

-/* The ns32k series is ah, unusual, when it comes to relocation.
- * There are three storage methods for relocateable objects. There
- * are displacements, immediate operands and ordinary twos complement
- * data. Of these, only the last fits into the standard relocation
- * scheme. Immediate operands are stored huffman encoded and
- * immediate operands are stored big endian (where as the natural byte
- * order is little endian for this achitecture).
-
- * Note that the ns32k displacement storage method is orthogonal to
- * whether the relocation is pc relative or not. The "displacement"
- * storage scheme is used for essentially all address constants. The
- * displacement can be relative to zero (absolute displacement),
- * relative to the pc (pc relative), the stack pointer, the frame
- * pointer, the static base register and general purpose register etc.
-
- * For example:
- *
- * sym1: .long . # pc relative 2's complement
- * sym1: .long foo # 2's complement not pc relative
- *
- * self: movd @self, r0 # pc relative displacement
- * movd foo, r0 # non pc relative displacement
- *
- * self: movd self, r0 # pc relative immediate
- * movd foo, r0 # non pc relative immediate
- *
- * In addition, for historical reasons the encoding of the relocation types
- * in the a.out format relocation entries is such that even the relocation
- * methods which are standard are not encoded the standard way.

-SECTION
- 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 @file{aoutx.h}
- and other files which derive functions from the base. One
- derivation file is @file{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 @file{sunos.c} for sun3 and sun4,
- @file{newsos3.c} for the Sony NEWS, and @file{demo64.c} for a
- demonstration of a 64 bit a.out format.
-
- The base file @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
- @file{aout32.c} and @file{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 @file{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 @file{sunos.c}:
-
-| #define TARGET_NAME "a.out-sunos-big"
-| #define VECNAME sunos_big_vec
-| #include "aoutf1.h"
-
- requires all the names from @file{aout32.c}, and produces the jump vector
-
-| sunos_big_vec
-
- The file @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 @file{../include/sys/h-@var{XXX}.h} (for your host). These
- values, plus the structures and macros defined in @file{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 @file{host-aout.c}, specify:
-
-| TDEFAULTS = -DDEFAULT_VECTOR=host_aout_big_vec
-| TDEPFILES= host-aout.o trad-core.o
-
- in the @file{config/@var{XXX}.mt} file, and modify @file{configure.in}
- to use the
- @file{@var{XXX}.mt} file (by setting "<<bfd_target=XXX>>") when your
- configuration is selected.
-
-*/
-
-/* Some assumptions:
- * Any BFD with D_PAGED set is ZMAGIC, and vice versa.
- Doesn't matter what the setting of WP_TEXT is on output, but it'll
- get set on input.
- * Any BFD with D_PAGED clear and WP_TEXT set is NMAGIC.
- * Any BFD with both flags clear is OMAGIC.
- (Just want to make these explicit, so the conditions tested in this
- file make sense if you're more familiar with a.out than with BFD.) */

-SECTION

-
-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>>.
-

-
-/* Assumes:
- o - all archive elements start on an even boundary, newline padded;
- o - all arch headers are char *;
- o - all arch headers are the same size (across architectures).
-*/
-
-/* Some formats provide a way to cram a long filename into the short
- (16 chars) space provided by a BSD archive. The trick is: make a
- special "file" in the front of the archive, sort of like the SYMDEF
- entry. If the filename is too long to fit, put it in the extended
- name table, and use its index as the filename. To prevent
- confusion prepend the index with a space. This means you can't
- have filenames that start with a space, but then again, many Unix
- utilities can't handle that anyway.
-
- This scheme unfortunately requires that you stand on your head in
- order to write an archive since you need to put a magic file at the
- front, and need to touch every entry to do so. C'est la vie.
-
- We support two variants of this idea:
- The SVR4 format (extended name table is named "//"),
- and an extended pseudo-BSD variant (extended name table is named
- "ARFILENAMES/"). The origin of the latter format is uncertain.
-
- BSD 4.4 uses a third scheme: It writes a long filename
- directly after the header. This allows 'ar q' to work.
- We currently can read BSD 4.4 archives, but not write them.

-/* Summary of archive member names:
-
- Symbol table (must be first):
- "__.SYMDEF " - Symbol table, Berkeley style, produced by ranlib.
- "/ " - Symbol table, system 5 style.
-
- Long name table (must be before regular file members):
- "// " - Long name table, System 5 R4 style.
- "ARFILENAMES/ " - Long name table, non-standard extended BSD (not BSD 4.4).
-
- Regular file members with short names:
- "filename.o/ " - Regular file, System 5 style (embedded spaces ok).

- 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.

-
-All the prototypes and definitions following the comment "THE FOLLOWING
-IS EXTRACTED FROM THE SOURCE" are extracted from the source files for
-BFD. If you change it, someone oneday will extract it from the source
-again, and your changes will be lost. To save yourself from this bind,
-change the definitions in the source in the bfd directory. Type "make
-docs" and then "make headers" in that directory, and magically this file
-will change to reflect your changes.
-
-If you don't have the tools to perform the extraction, then you are
-safe from someone on your system trampling over your header files.
-You should still maintain the equivalence between the source and this
-file though; every change you make to the .c file should be reflected

- 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>>.

-SYNOPSIS

-
-DESCRIPTION
- Return the file size (as read from file system) for the file
- associated with BFD @var{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 quesion, "is the
- size reasonable?".

-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.

- can present a better view of stubs.
-
- We can treat stubs like literal sections, and for the THUMB9 ones

- between sections. i.e. the simplest approach (since relocations
- are done on a section basis) is to dump the stubs at the end of

- offset to and from a stub. However, this does not map well onto
- the way that the linker/BFD does its work: mapping all input
- sections to output sections via the linker script before doing
- all the processing.
-
- Unfortunately it may be easier to just to disallow short range
- Thumb->ARM stubs (i.e. no conditional inter-working branches,
- only branch-and-link (BL) calls. This will simplify the processing
- since we can then put all of the stubs into their own section.

-/* XCOFF archive support. The original version of this code was by
- Damon A. Permezel. It was enhanced to permit cross support, and
- writing archive files, by Ian Lance Taylor, Cygnus Support.
-
- XCOFF uses its own archive format. Everything is hooked together
- with file offset links, so it is possible to rapidly update an
- archive in place. Of course, we don't do that. An XCOFF archive
- has a real file header, not just an ARMAG string. The structure of
- the file header and of each archive header appear below.
-
- An XCOFF archive also has a member table, which is a list of
- elements in the archive (you can get that by looking through the
- linked list, but you have to read a lot more of the file). The
- member table has a normal archive header with an empty name. It is
- normally (and perhaps must be) the second to last entry in the
- archive. The member table data is almost printable ASCII. It
- starts with a 12 character decimal string which is the number of
- entries in the table. For each entry it has a 12 character decimal
- string which is the offset in the archive of that member. These
- entries are followed by a series of null terminated strings which
- are the member names for each entry.
-
- Finally, an XCOFF archive has a global symbol table, which is what
- we call the armap. The global symbol table has a normal archive
- header with an empty name. It is normally (and perhaps must be)
- the last entry in the archive. The contents start with a four byte
- binary number which is the number of entries. This is followed by
- a that many four byte binary numbers; each is the file offset of an
- entry in the archive. These numbers are followed by a series of
- null terminated strings, which are symbol names. */

-
- Function calls on the SH look like this:
-
- movl L1,r0
- ...
- jsr @r0
- ...
- L1:
- .long function
-
- The compiler and assembler will cooperate to create R_SH_USES
- relocs on the jsr instructions. The r_offset field of the
- R_SH_USES reloc is the PC relative offset to the instruction which
- loads the register (the r_offset field is computed as though it
- were a jump instruction, so the offset value is actually from four
- bytes past the instruction). The linker can use this reloc to
- determine just which function is being called, and thus decide
- whether it is possible to replace the jsr with a bsr.
-
- If multiple function calls are all based on a single register load
- (i.e., the same function is called multiple times), the compiler
- guarantees that each function call will have an R_SH_USES reloc.
- Therefore, if the linker is able to convert each R_SH_USES reloc
- which refers to that address, it can safely eliminate the register
- load.
-
- When the assembler creates an R_SH_USES reloc, it examines it to
- determine which address is being loaded (L1 in the above example).
- It then counts the number of references to that address, and
- creates an R_SH_COUNT reloc at that address. The r_offset field of
- the R_SH_COUNT reloc will be the number of references. If the
- linker is able to eliminate a register load, it can use the
- R_SH_COUNT reloc to see whether it can also eliminate the function
- address.
-
- SH relaxing also handles another, unrelated, matter. On the SH, if
- a load or store instruction is not aligned on a four byte boundary,
- the memory cycle interferes with the 32 bit instruction fetch,
- causing a one cycle bubble in the pipeline. Therefore, we try to
- align load and store instructions on four byte boundaries if we
- can, by swapping them with one of the adjacent instructions. */

-SECTION
- 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
- @file{coff-m88k.c}. This file @code{#include}s
- @file{coff/m88k.h} which defines the external structure of the
- coff format for the 88k, and @file{coff/internal.h} which
- defines the internal structure. @file{coff-m88k.c} also
- defines the relocations used by the 88k format
- @xref{Relocations}.
-
- The Intel i960 processor version of coff is implemented in
- @file{coff-i960.c}. This file has the same structure as
- @file{coff-m88k.c}, except that it includes @file{coff/i960.h}
- rather than @file{coff-m88k.h}.
-
-SUBSECTION
- 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 @file{i386coff.c} to @file{foocoff.c}, copy
- @file{../include/coff/i386.h} to @file{../include/coff/foo.h},
- and add the lines to @file{targets.c} and @file{Makefile.in}
- so that your new back end is used. Alter the shapes of the
- structures in @file{../include/coff/foo.h} so that they match
- what you need. You will probably also have to add
- @code{#ifdef}s to the code in @file{coff/internal.h} and
- @file{coffcode.h} if your version of coff is too wild.
-
- You can verify that your new BFD backend works quite simply by
- building @file{objdump} from the @file{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 @code{att-dump} or just
- @code{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.
-
-SUBSECTION
- How the coff backend works
-
-SUBSUBSECTION
- 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 @file{coffgen.c}. These routines
- work for any Coff target. They use some hooks into the target
- specific code; the hooks are in a @code{bfd_coff_backend_data}
- structure, one of which exists for each target.
-
- The essentially similar target-specific routines are in
- @file{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 @file{coffcode.h}.
-
- Some of the Coff targets then also have additional routines in
- the target source file itself.
-
- For example, @file{coff-i960.c} includes
- @file{coff/internal.h} and @file{coff/i960.h}. It then
- defines a few constants, such as @code{I960}, and includes
- @file{coffcode.h}. Since the i960 has complex relocation
- types, @file{coff-i960.c} also includes some code to
- manipulate the i960 relocs. This code is not in
- @file{coffcode.h} because it would not be used by any other
- target.
-
-SUBSUBSECTION
- 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
- @file{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
- @code{bfd_swap}_@i{thing}_@i{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
- @file{coffcode.h}. E.g., the size of line number entry in coff is
- sometimes 16 bits, and sometimes 32 bits. @code{#define}ing
- @code{PUT_LNSZ_LNNO} and @code{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 @code{#defines}.
- Three of the bit twiddling routines are exported to
- @code{gdb}; @code{coff_swap_aux_in}, @code{coff_swap_sym_in}
- and @code{coff_swap_linno_in}. @code{GDB} reads the symbol
- table on its own, but uses BFD to fix things up. More of the
- bit twiddlers are exported for @code{gas};
- @code{coff_swap_aux_out}, @code{coff_swap_sym_out},
- @code{coff_swap_lineno_out}, @code{coff_swap_reloc_out},
- @code{coff_swap_filehdr_out}, @code{coff_swap_aouthdr_out},
- @code{coff_swap_scnhdr_out}. @code{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 @code{gas}, which makes one avenue to disaster disappear.
-
-SUBSUBSECTION
- 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
- @code{bfd_canonicalize_symtab}), a request gets through to
- @code{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
- (@code{".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
- @code{sclass} field) about the various flags to set in the
- @code{asymbol}. @xref{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.
-
-SUBSUBSECTION
- Symbol writing
-
- Writing a symbol to a coff file which didn't come from a coff
- file will lose any debugging information. The @code{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
- (@code{C_FILE}) to point to the next file place holder in the
- list. It also marks each @code{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 @code{asymbol}'s
- @code{asection} @xref{Sections}.
-
- o <<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 hierachy required by coff. It changes each pointer
- to a symbol into the index into the symbol table of the asymbol.
-
- o <<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.

-SUBSUBSECTION
- Reading relocations
-
- Coff relocations are easily transformed into the internal BFD form
- (@code{arelent}).
-
- Reading a coff relocation table is done in the following stages:
-
- o Read the entire coff relocation table into memory.
-
- o Process each relocation in turn; first swap it from the
- external to the internal form.
-
- o 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
- @code{bfd_canonicalize_symtab}. The back end will call that
- routine and save the result if a canonicalization hasn't been done.
-
- o 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 @code{r_type} to directly produce an index
- into a howto table vector; the 88k subtracts a number from the
- @code{r_type} field and creates an addend field.

-/* Thanks to Mike Haertel and Jim Avera for this test.
- Here is a matrix of mmap possibilities:
- mmap private not fixed
- mmap private fixed at somewhere currently unmapped
- mmap private fixed at somewhere already mapped
- mmap shared not fixed
- mmap shared fixed at somewhere currently unmapped
- mmap shared fixed at somewhere already mapped
- For private mappings, we should verify that changes cannot be read()
- back from the file, nor mmap's back from the file at a different
- address. (There have been systems where private was not correctly
- implemented like the infamous i386 svr4.0, and systems where the
- VM page cache was not coherent with the filesystem buffer cache
- like early versions of FreeBSD and possibly contemporary NetBSD.)
- For shared mappings, we should conversely verify that changes get
- propogated back to all the places they're supposed to be.
-
- Grep wants private fixed already mapped.
- The main things grep needs to know about mmap are:
- * does it exist and is it safe to write into the mmap'd area
- * how to use it (BSD variants) */

-/* Thanks to Mike Haertel and Jim Avera for this test.
- Here is a matrix of mmap possibilities:
- mmap private not fixed
- mmap private fixed at somewhere currently unmapped
- mmap private fixed at somewhere already mapped
- mmap shared not fixed
- mmap shared fixed at somewhere currently unmapped
- mmap shared fixed at somewhere already mapped
- For private mappings, we should verify that changes cannot be read()
- back from the file, nor mmap's back from the file at a different
- address. (There have been systems where private was not correctly
- implemented like the infamous i386 svr4.0, and systems where the
- VM page cache was not coherent with the filesystem buffer cache
- like early versions of FreeBSD and possibly contemporary NetBSD.)
- For shared mappings, we should conversely verify that changes get
- propogated back to all the places they're supposed to be.
-
- Grep wants private fixed already mapped.
- The main things grep needs to know about mmap are:
- * does it exist and is it safe to write into the mmap'd area
- * how to use it (BSD variants) */

-
-However, Ian wrote the following, regarding removing the line below,
-which explains why it is still enabled: --djm
-
-If you put a patch like that into BFD you need to check all the COFF
-linkers. I am fairly certain that patch will break coff-i386 (e.g.,
-SCO); see coff_i386_reloc in coff-i386.c where I worked around the
-problem in a different way. There may very well be a reason that the
-code works as it does.
-
-Hmmm. The first obvious point is that bfd_perform_relocation should
-not have any tests that depend upon the flavour. It's seem like
-entirely the wrong place for such a thing. The second obvious point
-is that the current code ignores the reloc addend when producing
-relocateable output for COFF. That's peculiar. In fact, I really
-have no idea what the point of the line you want to remove is.
-
-A typical COFF reloc subtracts the old value of the symbol and adds in
-the new value to the location in the object file (if it's a pc
-relative reloc it adds the difference between the symbol value and the
-location). When relocating we need to preserve that property.
-
-BFD handles this by setting the addend to the negative of the old
-value of the symbol. Unfortunately it handles common symbols in a
-non-standard way (it doesn't subtract the old value) but that's a
-different story (we can't change it without losing backward
-compatibility with old object files) (coff-i386 does subtract the old
-value, to be compatible with existing coff-i386 targets, like SCO).
-
-So everything works fine when not producing relocateable output. When
-we are producing relocateable output, logically we should do exactly
-what we do when not producing relocateable output. Therefore, your
-patch is correct. In fact, it should probably always just set
-reloc_entry->addend to 0 for all cases, since it is, in fact, going to
-add the value into the object file. This won't hurt the COFF code,
-which doesn't use the addend; I'm not sure what it will do to other
-formats (the thing to check for would be whether any formats both use
-the addend and set partial_inplace).
-
-When I wanted to make coff-i386 produce relocateable output, I ran
-into the problem that you are running into: I wanted to remove that
-line. Rather than risk it, I made the coff-i386 relocs use a special
-function; it's coff_i386_reloc in coff-i386.c. The function
-specifically adds the addend field into the object file, knowing that
-bfd_perform_relocation is not going to. If you remove that line, then
-coff-i386.c will wind up adding the addend field in twice. It's
-trivial to fix; it just needs to be done.
-
-The problem with removing the line is just that it may break some
-working code. With BFD it's hard to be sure of anything. The right
-way to deal with this is simply to build and test at least all the
-supported COFF targets. It should be straightforward if time and disk
-space consuming. For each target:
- 1) build the linker
- 2) generate some executable, and link it using -r (I would
- probably use paranoia.o and link against newlib/libc.a, which
- for all the supported targets would be available in
- /usr/cygnus/progressive/H-host/target/lib/libc.a).
- 3) make the change to reloc.c
- 4) rebuild the linker
- 5) repeat step 2
- 6) if the resulting object files are the same, you have at least
- made it no worse
- 7) if they are different you have to figure out which version is
- right

-@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.

-@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.

-@node BFD library interfaces
-@subsection BFD library interfaces
-
-One way to look at the BFD library is to divide it into four parts by
-type of interface.
-
-The first interface is the set of generic functions which programs using
-the BFD library will call. These generic function normally translate
-directly or indirectly into calls to routines which are specific to a
-particular object file format. Many of these generic functions are
-actually defined as macros in @file{bfd.h}. These functions comprise
-the official BFD interface.
-
-The second interface is the set of functions which appear in the target
-vectors. This is the bulk of the code in BFD. A target vector is a set
-of function pointers specific to a particular object file format. The
-target vector is used to implement the generic BFD functions. These
-functions are always called through the target vector, and are never
-called directly. The target vector is described in detail in @ref{BFD
-target vector}. The set of functions which appear in a particular
-target vector is often referred to as a BFD backend.
-
-The third interface is a set of oddball functions which are typically
-specific to a particular object file format, are not generic functions,
-and are called from outside of the BFD library. These are used as hooks
-by the linker and the assembler when a particular object file format
-requires some action which the BFD generic interface does not provide.
-These functions are typically declared in @file{bfd.h}, but in many
-cases they are only provided when BFD is configured with support for a
-particular object file format. These functions live in a grey area, and
-are not really part of the official BFD interface.
-
-The fourth interface is the set of BFD support functions which are
-called by the other BFD functions. These manage issues like memory
-allocation, error handling, file access, hash tables, swapping, and the
-like. These functions are never called from outside of the BFD library.
-
-@node BFD library users
-@subsection BFD library users
-
-Another way to look at the BFD library is to divide it into three parts
-by the manner in which it is used.
-
-The first use is to read an object file. The object file readers are
-programs like @samp{gdb}, @samp{nm}, @samp{objdump}, and @samp{objcopy}.
-These programs use BFD to view an object file in a generic form. The
-official BFD interface is normally fully adequate for these programs.
-
-The second use is to write an object file. The object file writers are
-programs like @samp{gas} and @samp{objcopy}. These programs use BFD to
-create an object file. The official BFD interface is normally adequate
-for these programs, but for some object file formats the assembler needs
-some additional hooks in order to set particular flags or other
-information. The official BFD interface includes functions to copy
-private information from one object file to another, and these functions
-are used by @samp{objcopy} to avoid information loss.
-
-The third use is to link object files. There is only one object file
-linker, @samp{ld}. Originally, @samp{ld} was an object file reader and
-an object file writer, and it did the link operation using the generic
-BFD structures. However, this turned out to be too slow and too memory
-intensive.
-
-The official BFD linker functions were written to permit specific BFD
-backends to perform the link without translating through the generic
-structures, in the normal case where all the input files and output file
-have the same object file format. Not all of the backends currently
-implement the new interface, and there are default linking functions
-within BFD which use the generic structures and which work with all
-backends.
-
-For several object file formats the linker needs additional hooks which
-are not provided by the official BFD interface, particularly for dynamic
-linking support. These functions are typically called from the linker
-emulation template.
-
-@node BFD view
-@subsection The BFD view of a file
-
-BFD uses generic structures to manage information. It translates data
-into the generic form when reading files, and out of the generic form
-when writing files.
-
-BFD describes a file as a pointer to the @samp{bfd} type. A @samp{bfd}
-is composed of the following elements. The BFD information can be
-displayed using the @samp{objdump} program with various options.
-
-@table @asis
-@item general information
-The object file format, a few general flags, the start address.
-@item architecture
-The architecture, including both a general processor type (m68k, MIPS
-etc.) and a specific machine number (m68000, R4000, etc.).
-@item sections
-A list of sections.
-@item symbols
-A symbol table.
-@end table
-
-BFD represents a section as a pointer to the @samp{asection} type. Each
-section has a name and a size. Most sections also have an associated
-block of data, known as the section contents. Sections also have
-associated flags, a virtual memory address, a load memory address, a
-required alignment, a list of relocations, and other miscellaneous
-information.
-
-BFD represents a relocation as a pointer to the @samp{arelent} type. A
-relocation describes an action which the linker must take to modify the
-section contents. Relocations have a symbol, an address, an addend, and
-a pointer to a howto structure which describes how to perform the
-relocation. For more information, see @ref{BFD relocation handling}.
-
-BFD represents a symbol as a pointer to the @samp{asymbol} type. A
-symbol has a name, a pointer to a section, an offset within that
-section, and some flags.
-
-Archive files do not have any sections or symbols. Instead, BFD
-represents an archive file as a file which contains a list of
-@samp{bfd}s. BFD also provides access to the archive symbol map, as a
-list of symbol names. BFD provides a function to return the @samp{bfd}
-within the archive which corresponds to a particular entry in the
-archive symbol map.
-
-@node BFD blindness
-@subsection BFD loses information
-
-Most object file formats have information which BFD can not represent in
-its generic form, at least as currently defined.
-
-There is often explicit information which BFD can not represent. For
-example, the COFF version stamp, or the ELF program segments. BFD
-provides special hooks to handle this information when copying,
-printing, or linking an object file. The BFD support for a particular
-object file format will normally store this information in private data
-and handle it using the special hooks.
-
-In some cases there is also implicit information which BFD can not
-represent. For example, the MIPS processor distinguishes small and
-large symbols, and requires that all small symbls be within 32K of the
-GP register. This means that the MIPS assembler must be able to mark
-variables as either small or large, and the MIPS linker must know to put
-small symbols within range of the GP register. Since BFD can not
-represent this information, this means that the assembler and linker
-must have information that is specific to a particular object file
-format which is outside of the BFD library.
-
-This loss of information indicates areas where the BFD paradigm breaks
-down. It is not actually possible to represent the myriad differences
-among object file formats using a single generic interface, at least not
-in the manner which BFD does it today.
-
-Nevertheless, the BFD library does greatly simplify the task of dealing
-with object files, and particular problems caused by information loss
-can normally be solved using some sort of relatively constrained hook
-into the library.

-@node BFD guidelines
-@section BFD programming guidelines
-@cindex bfd programming guidelines
-@cindex programming guidelines for bfd
-@cindex guidelines, bfd programming
-
-There is a lot of poorly written and confusing code in BFD. New BFD
-code should be written to a higher standard. Merely because some BFD
-code is written in a particular manner does not mean that you should
-emulate it.
-
-Here are some general BFD programming guidelines:
-
-@itemize @bullet
-@item
-Follow the GNU coding standards.
-
-@item
-Avoid global variables. We ideally want BFD to be fully reentrant, so
-that it can be used in multiple threads. All uses of global or static
-variables interfere with that. Initialized constant variables are OK,
-and they should be explicitly marked with const. Instead of global
-variables, use data attached to a BFD or to a linker hash table.
-
-@item
-All externally visible functions should have names which start with
-@samp{bfd_}. All such functions should be declared in some header file,
-typically @file{bfd.h}. See, for example, the various declarations near
-the end of @file{bfd-in.h}, which mostly declare functions required by
-specific linker emulations.
-
-@item
-All functions which need to be visible from one file to another within
-BFD, but should not be visible outside of BFD, should start with
-@samp{_bfd_}. Although external names beginning with @samp{_} are
-prohibited by the ANSI standard, in practice this usage will always
-work, and it is required by the GNU coding standards.
-
-@item
-Always remember that people can compile using @samp{--enable-targets} to
-build several, or all, targets at once. It must be possible to link
-together the files for all targets.
-
-@item
-BFD code should compile with few or no warnings using @samp{gcc -Wall}.
-Some warnings are OK, like the absence of certain function declarations
-which may or may not be declared in system header files. Warnings about
-ambiguous expressions and the like should always be fixed.

-behaviour that is specific to a particular object file format.
-
-In this section I list all of the entries in the target vector and

-@subsection Miscellaneous constants
-
-The target vector starts with a set of constants.
-
-@table @samp
-@item name
-The name of the target vector. This is an arbitrary string. This is
-how the target vector is named in command line options for tools which
-use BFD, such as the @samp{-oformat} linker option.
-
-@item flavour
-A general description of the type of target. The following flavours are
-currently defined:
-
-@table @samp
-@item bfd_target_unknown_flavour
-Undefined or unknown.
-@item bfd_target_aout_flavour
-a.out.
-@item bfd_target_coff_flavour
-COFF.
-@item bfd_target_ecoff_flavour
-ECOFF.
-@item bfd_target_elf_flavour
-ELF.
-@item bfd_target_ieee_flavour
-IEEE-695.
-@item bfd_target_nlm_flavour
-NLM.
-@item bfd_target_oasys_flavour
-OASYS.

-@item bfd_target_msdos_flavour
-MS-DOS.
-@item bfd_target_evax_flavour
-openVMS.
-@end table
-
-@item byteorder
-The byte order of data in the object file. One of
-@samp{BFD_ENDIAN_BIG}, @samp{BFD_ENDIAN_LITTLE}, or
-@samp{BFD_ENDIAN_UNKNOWN}. The latter would be used for a format such
-as S-records which do not record the architecture of the data.
-
-@item header_byteorder
-The byte order of header information in the object file. Normally the
-same as the @samp{byteorder} field, but there are certain cases where it
-may be different.
-
-@item object_flags
-Flags which may appear in the @samp{flags} field of a BFD with this
-format.
-
-@item section_flags
-Flags which may appear in the @samp{flags} field of a section within a
-BFD with this format.
-
-@item symbol_leading_char
-A character which the C compiler normally puts before a symbol. For
-example, an a.out compiler will typically generate the symbol
-@samp{_foo} for a function named @samp{foo} in the C source, in which
-case this field would be @samp{_}. If there is no such character, this
-field will be @samp{0}.
-
-@item ar_pad_char
-The padding character to use at the end of an archive name. Normally
-@samp{/}.
-
-@item ar_max_namelen
-The maximum length of a short name in an archive. Normally @samp{14}.
-
-@item backend_data
-A pointer to constant backend data. This is used by backends to store
-whatever additional information they need to distinguish similar target
-vectors which use the same sets of functions.
-@end table
-
-@node BFD target vector swap
-@subsection Swapping functions
-
-Every target vector has fuction pointers used for swapping information
-in and out of the target representation. There are two sets of
-functions: one for data information, and one for header information.
-Each set has three sizes: 64-bit, 32-bit, and 16-bit. Each size has
-three actual functions: put, get unsigned, and get signed.
-
-These 18 functions are used to convert data between the host and target
-representations.
-
-@node BFD target vector format
-@subsection Format type dependent functions
-
-Every target vector has three arrays of function pointers which are
-indexed by the BFD format type. The BFD format types are as follows:
-
-@table @samp
-@item bfd_unknown
-Unknown format. Not used for anything useful.
-@item bfd_object
-Object file.
-@item bfd_archive
-Archive file.
-@item bfd_core
-Core file.
-@end table
-
-The three arrays of function pointers are as follows:
-
-@table @samp
-@item bfd_check_format
-Check whether the BFD is of a particular format (object file, archive
-file, or core file) corresponding to this target vector. This is called
-by the @samp{bfd_check_format} function when examining an existing BFD.
-If the BFD matches the desired format, this function will initialize any
-format specific information such as the @samp{tdata} field of the BFD.
-This function must be called before any other BFD target vector function
-on a file opened for reading.
-
-@item bfd_set_format
-Set the format of a BFD which was created for output. This is called by
-the @samp{bfd_set_format} function after creating the BFD with a
-function such as @samp{bfd_openw}. This function will initialize format
-specific information required to write out an object file or whatever of
-the given format. This function must be called before any other BFD
-target vector function on a file opened for writing.
-
-@item bfd_write_contents
-Write out the contents of the BFD in the given format. This is called
-by @samp{bfd_close} function for a BFD opened for writing. This really
-should not be an array selected by format type, as the
-@samp{bfd_set_format} function provides all the required information.
-In fact, BFD will fail if a different format is used when calling
-through the @samp{bfd_set_format} and the @samp{bfd_write_contents}
-arrays; fortunately, since @samp{bfd_close} gets it right, this is a
-difficult error to make.
-@end table
-
-@node BFD_JUMP_TABLE macros
-@subsection @samp{BFD_JUMP_TABLE} macros
-@cindex @samp{BFD_JUMP_TABLE}
-
-Most target vectors are defined using @samp{BFD_JUMP_TABLE} macros.
-These macros take a single argument, which is a prefix applied to a set
-of functions. The macros are then used to initialize the fields in the
-target vector.
-
-For example, the @samp{BFD_JUMP_TABLE_RELOCS} macro defines three
-functions: @samp{_get_reloc_upper_bound}, @samp{_canonicalize_reloc},
-and @samp{_bfd_reloc_type_lookup}. A reference like
-@samp{BFD_JUMP_TABLE_RELOCS (foo)} will expand into three functions
-prefixed with @samp{foo}: @samp{foo_get_reloc_upper_found}, etc. The
-@samp{BFD_JUMP_TABLE_RELOCS} macro will be placed such that those three
-functions initialize the appropriate fields in the BFD target vector.
-
-This is done because it turns out that many different target vectors can
-share certain classes of functions. For example, archives are similar
-on most platforms, so most target vectors can use the same archive
-functions. Those target vectors all use @samp{BFD_JUMP_TABLE_ARCHIVE}
-with the same argument, calling a set of functions which is defined in
-@file{archive.c}.
-
-Each of the @samp{BFD_JUMP_TABLE} macros is mentioned below along with
-the description of the function pointers which it defines. The function
-pointers will be described using the name without the prefix which the
-@samp{BFD_JUMP_TABLE} macro defines. This name is normally the same as
-the name of the field in the target vector structure. Any differences
-will be noted.
-
-@node BFD target vector generic
-@subsection Generic functions
-@cindex @samp{BFD_JUMP_TABLE_GENERIC}
-
-The @samp{BFD_JUMP_TABLE_GENERIC} macro is used for some catch all
-functions which don't easily fit into other categories.
-
-@table @samp
-@item _close_and_cleanup
-Free any target specific information associated with the BFD. This is
-called when any BFD is closed (the @samp{bfd_write_contents} function
-mentioned earlier is only called for a BFD opened for writing). Most
-targets use @samp{bfd_alloc} to allocate all target specific
-information, and therefore don't have to do anything in this function.
-This function pointer is typically set to
-@samp{_bfd_generic_close_and_cleanup}, which simply returns true.
-
-@item _bfd_free_cached_info
-Free any cached information associated with the BFD which can be
-recreated later if necessary. This is used to reduce the memory
-consumption required by programs using BFD. This is normally called via
-the @samp{bfd_free_cached_info} macro. It is used by the default
-archive routines when computing the archive map. Most targets do not
-do anything special for this entry point, and just set it to
-@samp{_bfd_generic_free_cached_info}, which simply returns true.
-
-@item _new_section_hook
-This is called from @samp{bfd_make_section_anyway} whenever a new
-section is created. Most targets use it to initialize section specific
-information. This function is called whether or not the section
-corresponds to an actual section in an actual BFD.
-
-@item _get_section_contents
-Get the contents of a section. This is called from
-@samp{bfd_get_section_contents}. Most targets set this to
-@samp{_bfd_generic_get_section_contents}, which does a @samp{bfd_seek}
-based on the section's @samp{filepos} field and a @samp{bfd_read}. The
-corresponding field in the target vector is named
-@samp{_bfd_get_section_contents}.
-
-@item _get_section_contents_in_window
-Set a @samp{bfd_window} to hold the contents of a section. This is
-called from @samp{bfd_get_section_contents_in_window}. The
-@samp{bfd_window} idea never really caught on, and I don't think this is
-ever called. Pretty much all targets implement this as
-@samp{bfd_generic_get_section_contents_in_window}, which uses
-@samp{bfd_get_section_contents} to do the right thing. The
-corresponding field in the target vector is named
-@samp{_bfd_get_section_contents_in_window}.
-@end table
-
-@node BFD target vector copy
-@subsection Copy functions
-@cindex @samp{BFD_JUMP_TABLE_COPY}
-
-The @samp{BFD_JUMP_TABLE_COPY} macro is used for functions which are
-called when copying BFDs, and for a couple of functions which deal with
-internal BFD information.
-
-@table @samp
-@item _bfd_copy_private_bfd_data
-This is called when copying a BFD, via @samp{bfd_copy_private_bfd_data}.
-If the input and output BFDs have the same format, this will copy any
-private information over. This is called after all the section contents
-have been written to the output file. Only a few targets do anything in
-this function.
-
-@item _bfd_merge_private_bfd_data
-This is called when linking, via @samp{bfd_merge_private_bfd_data}. It
-gives the backend linker code a chance to set any special flags in the
-output file based on the contents of the input file. Only a few targets
-do anything in this function.
-
-@item _bfd_copy_private_section_data
-This is similar to @samp{_bfd_copy_private_bfd_data}, but it is called
-for each section, via @samp{bfd_copy_private_section_data}. This
-function is called before any section contents have been written. Only
-a few targets do anything in this function.
-
-@item _bfd_copy_private_symbol_data
-This is called via @samp{bfd_copy_private_symbol_data}, but I don't
-think anything actually calls it. If it were defined, it could be used
-to copy private symbol data from one BFD to another. However, most BFDs
-store extra symbol information by allocating space which is larger than
-the @samp{asymbol} structure and storing private information in the
-extra space. Since @samp{objcopy} and other programs copy symbol
-information by copying pointers to @samp{asymbol} structures, the
-private symbol information is automatically copied as well. Most
-targets do not do anything in this function.
-
-@item _bfd_set_private_flags
-This is called via @samp{bfd_set_private_flags}. It is basically a hook
-for the assembler to set magic information. For example, the PowerPC
-ELF assembler uses it to set flags which appear in the e_flags field of
-the ELF header. Most targets do not do anything in this function.
-
-@item _bfd_print_private_bfd_data
-This is called by @samp{objdump} when the @samp{-p} option is used. It
-is called via @samp{bfd_print_private_data}. It prints any interesting
-information about the BFD which can not be otherwise represented by BFD
-and thus can not be printed by @samp{objdump}. Most targets do not do
-anything in this function.
-@end table
-
-@node BFD target vector core
-@subsection Core file support functions
-@cindex @samp{BFD_JUMP_TABLE_CORE}
-
-The @samp{BFD_JUMP_TABLE_CORE} macro is used for functions which deal
-with core files. Obviously, these functions only do something
-interesting for targets which have core file support.
-
-@table @samp
-@item _core_file_failing_command
-Given a core file, this returns the command which was run to produce the
-core file.
-
-@item _core_file_failing_signal
-Given a core file, this returns the signal number which produced the
-core file.
-
-@item _core_file_matches_executable_p
-Given a core file and a BFD for an executable, this returns whether the
-core file was generated by the executable.
-@end table
-
-@node BFD target vector archive
-@subsection Archive functions
-@cindex @samp{BFD_JUMP_TABLE_ARCHIVE}
-
-The @samp{BFD_JUMP_TABLE_ARCHIVE} macro is used for functions which deal
-with archive files. Most targets use COFF style archive files
-(including ELF targets), and these use @samp{_bfd_archive_coff} as the
-argument to @samp{BFD_JUMP_TABLE_ARCHIVE}. Some targets use BSD/a.out
-style archives, and these use @samp{_bfd_archive_bsd}. (The main
-difference between BSD and COFF archives is the format of the archive
-symbol table). Targets with no archive support use
-@samp{_bfd_noarchive}. Finally, a few targets have unusual archive
-handling.
-
-@table @samp
-@item _slurp_armap
-Read in the archive symbol table, storing it in private BFD data. This
-is normally called from the archive @samp{check_format} routine. The
-corresponding field in the target vector is named
-@samp{_bfd_slurp_armap}.
-
-@item _slurp_extended_name_table
-Read in the extended name table from the archive, if there is one,
-storing it in private BFD data. This is normally called from the
-archive @samp{check_format} routine. The corresponding field in the
-target vector is named @samp{_bfd_slurp_extended_name_table}.
-
-@item construct_extended_name_table
-Build and return an extended name table if one is needed to write out
-the archive. This also adjusts the archive headers to refer to the
-extended name table appropriately. This is normally called from the
-archive @samp{write_contents} routine. The corresponding field in the
-target vector is named @samp{_bfd_construct_extended_name_table}.
-
-@item _truncate_arname
-This copies a file name into an archive header, truncating it as
-required. It is normally called from the archive @samp{write_contents}
-routine. This function is more interesting in targets which do not
-support extended name tables, but I think the GNU @samp{ar} program
-always uses extended name tables anyhow. The corresponding field in the
-target vector is named @samp{_bfd_truncate_arname}.
-
-@item _write_armap
-Write out the archive symbol table using calls to @samp{bfd_write}.
-This is normally called from the archive @samp{write_contents} routine.
-The corresponding field in the target vector is named @samp{write_armap}
-(no leading underscore).
-
-@item _read_ar_hdr
-Read and parse an archive header. This handles expanding the archive
-header name into the real file name using the extended name table. This
-is called by routines which read the archive symbol table or the archive
-itself. The corresponding field in the target vector is named
-@samp{_bfd_read_ar_hdr_fn}.
-
-@item _openr_next_archived_file
-Given an archive and a BFD representing a file stored within the
-archive, return a BFD for the next file in the archive. This is called
-via @samp{bfd_openr_next_archived_file}. The corresponding field in the
-target vector is named @samp{openr_next_archived_file} (no leading
-underscore).
-
-@item _get_elt_at_index
-Given an archive and an index, return a BFD for the file in the archive
-corresponding to that entry in the archive symbol table. This is called
-via @samp{bfd_get_elt_at_index}. The corresponding field in the target
-vector is named @samp{_bfd_get_elt_at_index}.
-
-@item _generic_stat_arch_elt
-Do a stat on an element of an archive, returning information read from
-the archive header (modification time, uid, gid, file mode, size). This
-is called via @samp{bfd_stat_arch_elt}. The corresponding field in the
-target vector is named @samp{_bfd_stat_arch_elt}.
-
-@item _update_armap_timestamp
-After the entire contents of an archive have been written out, update
-the timestamp of the archive symbol table to be newer than that of the
-file. This is required for a.out style archives. This is normally
-called by the archive @samp{write_contents} routine. The corresponding
-field in the target vector is named @samp{_bfd_update_armap_timestamp}.
-@end table
-
-@node BFD target vector symbols
-@subsection Symbol table functions
-@cindex @samp{BFD_JUMP_TABLE_SYMBOLS}
-
-The @samp{BFD_JUMP_TABLE_SYMBOLS} macro is used for functions which deal
-with symbols.
-
-@table @samp
-@item _get_symtab_upper_bound
-Return a sensible upper bound on the amount of memory which will be
-required to read the symbol table. In practice most targets return the
-amount of memory required to hold @samp{asymbol} pointers for all the
-symbols plus a trailing @samp{NULL} entry, and store the actual symbol
-information in BFD private data. This is called via
-@samp{bfd_get_symtab_upper_bound}. The corresponding field in the
-target vector is named @samp{_bfd_get_symtab_upper_bound}.
-
-@item _get_symtab
-Read in the symbol table. This is called via
-@samp{bfd_canonicalize_symtab}. The corresponding field in the target
-vector is named @samp{_bfd_canonicalize_symtab}.
-
-@item _make_empty_symbol
-Create an empty symbol for the BFD. This is needed because most targets
-store extra information with each symbol by allocating a structure
-larger than an @samp{asymbol} and storing the extra information at the
-end. This function will allocate the right amount of memory, and return
-what looks like a pointer to an empty @samp{asymbol}. This is called
-via @samp{bfd_make_empty_symbol}. The corresponding field in the target
-vector is named @samp{_bfd_make_empty_symbol}.
-
-@item _print_symbol
-Print information about the symbol. This is called via
-@samp{bfd_print_symbol}. One of the arguments indicates what sort of
-information should be printed:
-
-@table @samp
-@item bfd_print_symbol_name
-Just print the symbol name.
-@item bfd_print_symbol_more
-Print the symbol name and some interesting flags. I don't think
-anything actually uses this.
-@item bfd_print_symbol_all
-Print all information about the symbol. This is used by @samp{objdump}
-when run with the @samp{-t} option.
-@end table
-The corresponding field in the target vector is named
-@samp{_bfd_print_symbol}.
-
-@item _get_symbol_info
-Return a standard set of information about the symbol. This is called
-via @samp{bfd_symbol_info}. The corresponding field in the target
-vector is named @samp{_bfd_get_symbol_info}.
-
-@item _bfd_is_local_label_name
-Return whether the given string would normally represent the name of a
-local label. This is called via @samp{bfd_is_local_label} and
-@samp{bfd_is_local_label_name}. Local labels are normally discarded by
-the assembler. In the linker, this defines the difference between the
-@samp{-x} and @samp{-X} options.
-
-@item _get_lineno
-Return line number information for a symbol. This is only meaningful
-for a COFF target. This is called when writing out COFF line numbers.
-
-@item _find_nearest_line
-Given an address within a section, use the debugging information to find
-the matching file name, function name, and line number, if any. This is
-called via @samp{bfd_find_nearest_line}. The corresponding field in the
-target vector is named @samp{_bfd_find_nearest_line}.
-
-@item _bfd_make_debug_symbol
-Make a debugging symbol. This is only meaningful for a COFF target,
-where it simply returns a symbol which will be placed in the
-@samp{N_DEBUG} section when it is written out. This is called via
-@samp{bfd_make_debug_symbol}.
-
-@item _read_minisymbols
-Minisymbols are used to reduce the memory requirements of programs like
-@samp{nm}. A minisymbol is a cookie pointing to internal symbol
-information which the caller can use to extract complete symbol
-information. This permits BFD to not convert all the symbols into
-generic form, but to instead convert them one at a time. This is called
-via @samp{bfd_read_minisymbols}. Most targets do not implement this,
-and just use generic support which is based on using standard
-@samp{asymbol} structures.
-
-@item _minisymbol_to_symbol
-Convert a minisymbol to a standard @samp{asymbol}. This is called via
-@samp{bfd_minisymbol_to_symbol}.
-@end table
-
-@node BFD target vector relocs
-@subsection Relocation support
-@cindex @samp{BFD_JUMP_TABLE_RELOCS}
-
-The @samp{BFD_JUMP_TABLE_RELOCS} macro is used for functions which deal
-with relocations.
-
-@table @samp
-@item _get_reloc_upper_bound
-Return a sensible upper bound on the amount of memory which will be
-required to read the relocations for a section. In practice most
-targets return the amount of memory required to hold @samp{arelent}
-pointers for all the relocations plus a trailing @samp{NULL} entry, and
-store the actual relocation information in BFD private data. This is
-called via @samp{bfd_get_reloc_upper_bound}.
-
-@item _canonicalize_reloc
-Return the relocation information for a section. This is called via
-@samp{bfd_canonicalize_reloc}. The corresponding field in the target
-vector is named @samp{_bfd_canonicalize_reloc}.
-
-@item _bfd_reloc_type_lookup
-Given a relocation code, return the corresponding howto structure
-(@pxref{BFD relocation codes}). This is called via

-@item _set_arch_mach
-Set the architecture and machine number for a BFD. This is called via
-@samp{bfd_set_arch_mach}. Most targets implement this by calling
-@samp{bfd_default_set_arch_mach}. The corresponding field in the target
-vector is named @samp{_bfd_set_arch_mach}.
-
-@item _set_section_contents
-Write out the contents of a section. This is called via

-
-The @samp{BFD_JUMP_TABLE_LINK} macro is used for functions called by the
-linker.
-
-@table @samp
-@item _sizeof_headers
-Return the size of the header information required for a BFD. This is
-used to implement the @samp{SIZEOF_HEADERS} linker script function. It
-is normally used to align the first section at an efficient position on
-the page. This is called via @samp{bfd_sizeof_headers}. The
-corresponding field in the target vector is named
-@samp{_bfd_sizeof_headers}.
-
-@item _bfd_get_relocated_section_contents
-Read the contents of a section and apply the relocation information.
-This handles both a final link and a relocateable link; in the latter
-case, it adjust the relocation information as well. This is called via
-@samp{bfd_get_relocated_section_contents}. Most targets implement it by
-calling @samp{bfd_generic_get_relocated_section_contents}.
-
-@item _bfd_relax_section
-Try to use relaxation to shrink the size of a section. This is called
-by the linker when the @samp{-relax} option is used. This is called via
-@samp{bfd_relax_section}. Most targets do not support any sort of
-relaxation.
-
-@item _bfd_link_hash_table_create
-Create the symbol hash table to use for the linker. This linker hook
-permits the backend to control the size and information of the elements
-in the linker symbol hash table. This is called via
-@samp{bfd_link_hash_table_create}.
-
-@item _bfd_link_add_symbols
-Given an object file or an archive, add all symbols into the linker
-symbol hash table. Use callbacks to the linker to include archive
-elements in the link. This is called via @samp{bfd_link_add_symbols}.
-
-@item _bfd_final_link
-Finish the linking process. The linker calls this hook after all of the
-input files have been read, when it is ready to finish the link and
-generate the output file. This is called via @samp{bfd_final_link}.
-
-@item _bfd_link_split_section

-@node BFD multiple compilations
-@section Files compiled multiple times in BFD
-Several files in BFD are compiled multiple times. By this I mean that
-there are header files which contain function definitions. These header
-files are included by other files, and thus the functions are compiled
-once per file which includes them.
-
-Preprocessor macros are used to control the compilation, so that each
-time the files are compiled the resulting functions are slightly
-different. Naturally, if they weren't different, there would be no
-reason to compile them multiple times.
-
-This is a not a particularly good programming technique, and future BFD
-work should avoid it.
-
-@itemize @bullet
-@item
-Since this technique is rarely used, even experienced C programmers find
-it confusing.
-
-@item
-It is difficult to debug programs which use BFD, since there is no way
-to describe which version of a particular function you are looking at.
-
-@item
-Programs which use BFD wind up incorporating two or more slightly
-different versions of the same function, which wastes space in the
-executable.
-
-@item
-This technique is never required nor is it especially efficient. It is
-always possible to use statically initialized structures holding
-function pointers and magic constants instead.
-@end itemize
-
-The following is a list of the files which are compiled multiple times.
-
-@table @file
-@item aout-target.h
-@cindex @file{aout-target.h}
-Describes a few functions and the target vector for a.out targets. This
-is used by individual a.out targets with different definitions of
-@samp{N_TXTADDR} and similar a.out macros.
-
-@item aoutf1.h
-@cindex @file{aoutf1.h}
-Implements standard SunOS a.out files. In principle it supports 64 bit
-a.out targets based on the preprocessor macro @samp{ARCH_SIZE}, but
-since all known a.out targets are 32 bits, this code may or may not
-work. This file is only included by a few other files, and it is
-difficult to justify its existence.
-
-@item aoutx.h
-@cindex @file{aoutx.h}
-Implements basic a.out support routines. This file can be compiled for
-either 32 or 64 bit support. Since all known a.out targets are 32 bits,
-the 64 bit support may or may not work. I believe the original
-intention was that this file would only be included by @samp{aout32.c}
-and @samp{aout64.c}, and that other a.out targets would simply refer to
-the functions it defined. Unfortunately, some other a.out targets
-started including it directly, leading to a somewhat confused state of
-affairs.
-
-@item coffcode.h
-@cindex @file{coffcode.h}
-Implements basic COFF support routines. This file is included by every
-COFF target. It implements code which handles COFF magic numbers as
-well as various hook functions called by the generic COFF functions in
-@file{coffgen.c}. This file is controlled by a number of different
-macros, and more are added regularly.
-
-@item coffswap.h
-@cindex @file{coffswap.h}
-Implements COFF swapping routines. This file is included by
-@file{coffcode.h}, and thus by every COFF target. It implements the
-routines which swap COFF structures between internal and external
-format. The main control for this file is the external structure
-definitions in the files in the @file{include/coff} directory. A COFF
-target file will include one of those files before including
-@file{coffcode.h} and thus @file{coffswap.h}. There are a few other
-macros which affect @file{coffswap.h} as well, mostly describing whether
-certain fields are present in the external structures.
-
-@item ecoffswap.h
-@cindex @file{ecoffswap.h}
-Implements ECOFF swapping routines. This is like @file{coffswap.h}, but
-for ECOFF. It is included by the ECOFF target files (of which there are
-only two). The control is the preprocessor macro @samp{ECOFF_32} or
-@samp{ECOFF_64}.
-
-@item elfcode.h
-@cindex @file{elfcode.h}
-Implements ELF functions that use external structure definitions. This
-file is included by two other files: @file{elf32.c} and @file{elf64.c}.
-It is controlled by the @samp{ARCH_SIZE} macro which is defined to be
-@samp{32} or @samp{64} before including it. The @samp{NAME} macro is
-used internally to give the functions different names for the two target
-sizes.
-
-@item elfcore.h
-@cindex @file{elfcore.h}
-Like @file{elfcode.h}, but for functions that are specific to ELF core
-files. This is included only by @file{elfcode.h}.
-
-@item elflink.h
-@cindex @file{elflink.h}
-Like @file{elfcode.h}, but for functions used by the ELF linker. This
-is included only by @file{elfcode.h}.
-
-@item elfxx-target.h
-@cindex @file{elfxx-target.h}
-This file is the source for the generated files @file{elf32-target.h}
-and @file{elf64-target.h}, one of which is included by every ELF target.
-It defines the ELF target vector.
-
-@item freebsd.h
-@cindex @file{freebsd.h}
-Presumably intended to be included by all FreeBSD targets, but in fact
-there is only one such target, @samp{i386-freebsd}. This defines a
-function used to set the right magic number for FreeBSD, as well as
-various macros, and includes @file{aout-target.h}.
-
-@item netbsd.h
-@cindex @file{netbsd.h}
-Like @file{freebsd.h}, except that there are several files which include
-it.
-
-@item nlm-target.h
-@cindex @file{nlm-target.h}
-Defines the target vector for a standard NLM target.
-
-@item nlmcode.h
-@cindex @file{nlmcode.h}
-Like @file{elfcode.h}, but for NLM targets. This is only included by
-@file{nlm32.c} and @file{nlm64.c}, both of which define the macro
-@samp{ARCH_SIZE} to an appropriate value. There are no 64 bit NLM
-targets anyhow, so this is sort of useless.
-
-@item nlmswap.h
-@cindex @file{nlmswap.h}
-Like @file{coffswap.h}, but for NLM targets. This is included by each
-NLM target, but I think it winds up compiling to the exact same code for
-every target, and as such is fairly useless.
-
-@item peicode.h
-@cindex @file{peicode.h}
-Provides swapping routines and other hooks for PE targets.
-@file{coffcode.h} will include this rather than @file{coffswap.h} for a
-PE target. This defines PE specific versions of the COFF swapping
-routines, and also defines some macros which control @file{coffcode.h}
-itself.

-@subsection BFD relocation concepts
-
-A relocation is an action which the linker must take when linking. It
-describes a change to the contents of a section. The change is normally
-based on the final value of one or more symbols. Relocations are
-created by the assembler when it creates an object file.
-
-Most relocations are simple. A typical simple relocation is to set 32
-bits at a given offset in a section to the value of a symbol. This type
-of relocation would be generated for code like @code{int *p = &i;} where
-@samp{p} and @samp{i} are global variables. A relocation for the symbol
-@samp{i} would be generated such that the linker would initialize the
-area of memory which holds the value of @samp{p} to the value of the
-symbol @samp{i}.
-
-Slightly more complex relocations may include an addend, which is a
-constant to add to the symbol value before using it. In some cases a
-relocation will require adding the symbol value to the existing contents
-of the section in the object file. In others the relocation will simply
-replace the contents of the section with the symbol value. Some
-relocations are PC relative, so that the value to be stored in the
-section is the difference between the value of a symbol and the final
-address of the section contents.
-
-In general, relocations can be arbitrarily complex. For example,
-relocations used in dynamic linking systems often require the linker to
-allocate space in a different section and use the offset within that
-section as the value to store. In the IEEE object file format,
-relocations may involve arbitrary expressions.
-
-When doing a relocateable link, the linker may or may not have to do
-anything with a relocation, depending upon the definition of the
-relocation. Simple relocations generally do not require any special
-action.
-
-@node BFD relocation functions
-@subsection BFD relocation functions
-
-In BFD, each section has an array of @samp{arelent} structures. Each
-structure has a pointer to a symbol, an address within the section, an
-addend, and a pointer to a @samp{reloc_howto_struct} structure. The
-howto structure has a bunch of fields describing the reloc, including a
-type field. The type field is specific to the object file format
-backend; none of the generic code in BFD examines it.
-
-Originally, the function @samp{bfd_perform_relocation} was supposed to
-handle all relocations. In theory, many relocations would be simple
-enough to be described by the fields in the howto structure. For those
-that weren't, the howto structure included a @samp{special_function}
-field to use as an escape.
-
-While this seems plausible, a look at @samp{bfd_perform_relocation}
-shows that it failed. The function has odd special cases. Some of the
-fields in the howto structure, such as @samp{pcrel_offset}, were not
-adequately documented.
-
-The linker uses @samp{bfd_perform_relocation} to do all relocations when
-the input and output file have different formats (e.g., when generating
-S-records). The generic linker code, which is used by all targets which
-do not define their own special purpose linker, uses
-@samp{bfd_get_relocated_section_contents}, which for most targets turns
-into a call to @samp{bfd_generic_get_relocated_section_contents}, which
-calls @samp{bfd_perform_relocation}. So @samp{bfd_perform_relocation}
-is still widely used, which makes it difficult to change, since it is
-difficult to test all possible cases.
-
-The assembler used @samp{bfd_perform_relocation} for a while. This
-turned out to be the wrong thing to do, since
-@samp{bfd_perform_relocation} was written to handle relocations on an
-existing object file, while the assembler needed to create relocations
-in a new object file. The assembler was changed to use the new function
-@samp{bfd_install_relocation} instead, and @samp{bfd_install_relocation}
-was created as a copy of @samp{bfd_perform_relocation}.
-
-Unfortunately, the work did not progress any farther, so
-@samp{bfd_install_relocation} remains a simple copy of
-@samp{bfd_perform_relocation}, with all the odd special cases and
-confusing code. This again is difficult to change, because again any
-change can affect any assembler target, and so is difficult to test.
-
-The new linker, when using the same object file format for all input
-files and the output file, does not convert relocations into
-@samp{arelent} structures, so it can not use
-@samp{bfd_perform_relocation} at all. Instead, users of the new linker
-are expected to write a @samp{relocate_section} function which will
-handle relocations in a target specific fashion.
-
-There are two helper functions for target specific relocation:
-@samp{_bfd_final_link_relocate} and @samp{_bfd_relocate_contents}.
-These functions use a howto structure, but they @emph{do not} use the
-@samp{special_function} field. Since the functions are normally called
-from target specific code, the @samp{special_function} field adds
-little; any relocations which require special handling can be handled
-without calling those functions.
-
-So, if you want to add a new target, or add a new relocation to an
-existing target, you need to do the following:
-
-@itemize @bullet
-@item
-Make sure you clearly understand what the contents of the section should
-look like after assembly, after a relocateable link, and after a final
-link. Make sure you clearly understand the operations the linker must
-perform during a relocateable link and during a final link.
-
-@item
-Write a howto structure for the relocation. The howto structure is
-flexible enough to represent any relocation which should be handled by
-setting a contiguous bitfield in the destination to the value of a
-symbol, possibly with an addend, possibly adding the symbol value to the
-value already present in the destination.
-
-@item
-Change the assembler to generate your relocation. The assembler will
-call @samp{bfd_install_relocation}, so your howto structure has to be
-able to handle that. You may need to set the @samp{special_function}
-field to handle assembly correctly. Be careful to ensure that any code
-you write to handle the assembler will also work correctly when doing a
-relocateable link. For example, see @samp{bfd_elf_generic_reloc}.
-
-@item
-Test the assembler. Consider the cases of relocation against an
-undefined symbol, a common symbol, a symbol defined in the object file
-in the same section, and a symbol defined in the object file in a
-different section. These cases may not all be applicable for your
-reloc.
-
-@item
-If your target uses the new linker, which is recommended, add any
-required handling to the target specific relocation function. In simple
-cases this will just involve a call to @samp{_bfd_final_link_relocate}
-or @samp{_bfd_relocate_contents}, depending upon the definition of the
-relocation and whether the link is relocateable or not.
-
-@item
-Test the linker. Test the case of a final link. If the relocation can
-overflow, use a linker script to force an overflow and make sure the
-error is reported correctly. Test a relocateable link, whether the
-symbol is defined or undefined in the relocateable output. For both the
-final and relocateable link, test the case when the symbol is a common
-symbol, when the symbol looked like a common symbol but became a defined
-symbol, when the symbol is defined in a different object file, and when
-the symbol is defined in the same object file.
-
-@item
-In order for linking to another object file format, such as S-records,
-to work correctly, @samp{bfd_perform_relocation} has to do the right
-thing for the relocation. You may need to set the
-@samp{special_function} field to handle this correctly. Test this by
-doing a link in which the output object file format is S-records.
-
-@item
-Using the linker to generate relocateable output in a different object
-file format is impossible in the general case, so you generally don't
-have to worry about that. Linking input files of different object file
-formats together is quite unusual, but if you're really dedicated you
-may want to consider testing this case, both when the output object file
-format is the same as your format, and when it is different.
-@end itemize
-
-@node BFD relocation codes
-@subsection BFD relocation codes
-
-BFD has another way of describing relocations besides the howto
-structures described above: the enum @samp{bfd_reloc_code_real_type}.
-
-Every known relocation type can be described as a value in this
-enumeration. The enumeration contains many target specific relocations,
-but where two or more targets have the same relocation, a single code is
-used. For example, the single value @samp{BFD_RELOC_32} is used for all
-simple 32 bit relocation types.
-
-The main purpose of this relocation code is to give the assembler some
-mechanism to create @samp{arelent} structures. In order for the
-assembler to create an @samp{arelent} structure, it has to be able to
-obtain a howto structure. The function @samp{bfd_reloc_type_lookup},
-which simply calls the target vector entry point
-@samp{reloc_type_lookup}, takes a relocation code and returns a howto
-structure.
-
-The function @samp{bfd_get_reloc_code_name} returns the name of a
-relocation code. This is mainly used in error messages.
-
-Using both howto structures and relocation codes can be somewhat
-confusing. There are many processor specific relocation codes.
-However, the relocation is only fully defined by the howto structure.
-The same relocation code will map to different howto structures in
-different object file formats. For example, the addend handling may be
-different.
-
-Most of the relocation codes are not really general. The assembler can
-not use them without already understanding what sorts of relocations can
-be used for a particular target. It might be possible to replace the
-relocation codes with something simpler.
-
-@node BFD relocation future
-@subsection BFD relocation future
-
-Clearly the current BFD relocation support is in bad shape. A
-wholescale rewrite would be very difficult, because it would require
-thorough testing of every BFD target. So some sort of incremental
-change is required.
-
-My vague thoughts on this would involve defining a new, clearly defined,
-howto structure. Some mechanism would be used to determine which type
-of howto structure was being used by a particular format.
-
-The new howto structure would clearly define the relocation behaviour in
-the case of an assembly, a relocateable link, and a final link. At
-least one special function would be defined as an escape, and it might
-make sense to define more.
-
-One or more generic functions similar to @samp{bfd_perform_relocation}
-would be written to handle the new howto structure.
-
-This should make it possible to write a generic version of the relocate
-section functions used by the new linker. The target specific code
-would provide some mechanism (a function pointer or an initial
-conversion) to convert target specific relocations into howto
-structures.
-
-Ideally it would be possible to use this generic relocate section
-function for the generic linker as well. That is, it would replace the
-@samp{bfd_generic_get_relocated_section_contents} function which is
-currently normally used.
-
-For the special case of ELF dynamic linking, more consideration needs to
-be given to writing ELF specific but ELF target generic code to handle
-special relocation types such as GOT and PLT.

-@node BFD ELF support

-
-The ELF object file format is defined in two parts: a generic ABI and a
-processor specific supplement. The ELF support in BFD is split in a
-similar fashion. The processor specific support is largely kept within
-a single file. The generic support is provided by several other files.
-The processor specific support provides a set of function pointers and

-
-@node BFD ELF sections and segments
-@subsection ELF sections and segments
-
-The ELF ABI permits a file to have either sections or segments or both.
-Relocateable object files conventionally have only sections.
-Executables conventionally have both. Core files conventionally have
-only program segments.
-
-ELF sections are similar to sections in other object file formats: they
-have a name, a VMA, file contents, flags, and other miscellaneous
-information. ELF relocations are stored in sections of a particular
-type; BFD automatically converts these sections into internal relocation
-information.
-
-ELF program segments are intended for fast interpretation by a system
-loader. They have a type, a VMA, an LMA, file contents, and a couple of
-other fields. When an ELF executable is run on a Unix system, the
-system loader will examine the program segments to decide how to load
-it. The loader will ignore the section information. Loadable program
-segments (type @samp{PT_LOAD}) are directly loaded into memory. Other
-program segments are interpreted by the loader, and generally provide
-dynamic linking information.
-
-When an ELF file has both program segments and sections, an ELF program
-segment may encompass one or more ELF sections, in the sense that the
-portion of the file which corresponds to the program segment may include
-the portions of the file corresponding to one or more sections. When
-there is more than one section in a loadable program segment, the
-relative positions of the section contents in the file must correspond
-to the relative positions they should hold when the program segment is
-loaded. This requirement should be obvious if you consider that the
-system loader will load an entire program segment at a time.
-
-On a system which supports dynamic paging, such as any native Unix
-system, the contents of a loadable program segment must be at the same
-offset in the file as in memory, modulo the memory page size used on the
-system. This is because the system loader will map the file into memory
-starting at the start of a page. The system loader can easily remap
-entire pages to the correct load address. However, if the contents of
-the file were not correctly aligned within the page, the system loader
-would have to shift the contents around within the page, which is too
-expensive. For example, if the LMA of a loadable program segment is
-@samp{0x40080} and the page size is @samp{0x1000}, then the position of
-the segment contents within the file must equal @samp{0x80} modulo
-@samp{0x1000}.
-
-BFD has only a single set of sections. It does not provide any generic
-way to examine both sections and segments. When BFD is used to open an
-object file or executable, the BFD sections will represent ELF sections.
-When BFD is used to open a core file, the BFD sections will represent
-ELF program segments.
-
-When BFD is used to examine an object file or executable, any program
-segments will be read to set the LMA of the sections. This is because
-ELF sections only have a VMA, while ELF program segments have both a VMA
-and an LMA. Any program segments will be copied by the
-@samp{copy_private} entry points. They will be printed by the
-@samp{print_private} entry point. Otherwise, the program segments are
-ignored. In particular, programs which use BFD currently have no direct
-access to the program segments.
-
-When BFD is used to create an executable, the program segments will be
-created automatically based on the section information. This is done in
-the function @samp{assign_file_positions_for_segments} in @file{elf.c}.
-This function has been tweaked many times, and probably still has
-problems that arise in particular cases.
-
-There is a hook which may be used to explicitly define the program
-segments when creating an executable: the @samp{bfd_record_phdr}
-function in @file{bfd.c}. If this function is called, BFD will not
-create program segments itself, but will only create the program
-segments specified by the caller. The linker uses this function to
-implement the @samp{PHDRS} linker script command.
-
-@node BFD ELF generic support
-@subsection BFD ELF generic support
-
-In general, functions which do not read external data from the ELF file
-are found in @file{elf.c}. They operate on the internal forms of the
-ELF structures, which are defined in @file{include/elf/internal.h}. The
-internal structures are defined in terms of @samp{bfd_vma}, and so may
-be used for both 32 bit and 64 bit ELF targets.
-
-The file @file{elfcode.h} contains functions which operate on the
-external data. @file{elfcode.h} is compiled twice, once via
-@file{elf32.c} with @samp{ARCH_SIZE} defined as @samp{32}, and once via

-@file{elfcode.h} includes functions to swap the ELF structures in and

-
-Linker support is found in @file{elflink.c} and @file{elflink.h}. The

-linker support is only used if the processor specific file defines

-is used, and relocations are handled via @samp{bfd_perform_relocation}.
-
-The core file support is in @file{elfcore.h}, which is compiled twice,
-for both 32 and 64 bit support. The more interesting cases of core file
-support only work on a native system which has the @file{sys/procfs.h}
-header file. Without that file, the core file support does little more

-@node BFD ELF processor required
-@subsubsection Required processor specific support
-
-When writing a @file{elf@var{nn}-@var{cpu}.c} file, you must do the
-following:
-
-@itemize @bullet
-@item
-Define either @samp{TARGET_BIG_SYM} or @samp{TARGET_LITTLE_SYM}, or
-both, to a unique C name to use for the target vector. This name should
-appear in the list of target vectors in @file{targets.c}, and will also
-have to appear in @file{config.bfd} and @file{configure.in}. Define
-@samp{TARGET_BIG_SYM} for a big-endian processor,
-@samp{TARGET_LITTLE_SYM} for a little-endian processor, and define both
-for a bi-endian processor.
-@item
-Define either @samp{TARGET_BIG_NAME} or @samp{TARGET_LITTLE_NAME}, or
-both, to a string used as the name of the target vector. This is the
-name which a user of the BFD tool would use to specify the object file
-format. It would normally appear in a linker emulation parameters
-file.
-@item
-Define @samp{ELF_ARCH} to the BFD architecture (an element of the
-@samp{bfd_architecture} enum, typically @samp{bfd_arch_@var{cpu}}).
-@item
-Define @samp{ELF_MACHINE_CODE} to the magic number which should appear
-in the @samp{e_machine} field of the ELF header. As of this writing,
-these magic numbers are assigned by SCO; if you want to get a magic
-number for a particular processor, try sending a note to
-@email{registry@@sco.com}. In the BFD sources, the magic numbers are
-found in @file{include/elf/common.h}; they have names beginning with
-@samp{EM_}.
-@item
-Define @samp{ELF_MAXPAGESIZE} to the maximum size of a virtual page in
-memory. This can normally be found at the start of chapter 5 in the
-processor specific supplement. For a processor which will only be used
-in an embedded system, or which has no memory management hardware, this
-can simply be @samp{1}.
-@item
-If the format should use @samp{Rel} rather than @samp{Rela} relocations,
-define @samp{USE_REL}. This is normally defined in chapter 4 of the
-processor specific supplement.
-
-In the absence of a supplement, it's easier to work with @samp{Rela}
-relocations. @samp{Rela} relocations will require more space in object
-files (but not in executables, except when using dynamic linking).
-However, this is outweighed by the simplicity of addend handling when
-using @samp{Rela} relocations. With @samp{Rel} relocations, the addend
-must be stored in the section contents, which makes relocateable links
-more complex.
-
-For example, consider C code like @code{i = a[1000];} where @samp{a} is
-a global array. The instructions which load the value of @samp{a[1000]}
-will most likely use a relocation which refers to the symbol
-representing @samp{a}, with an addend that gives the offset from the
-start of @samp{a} to element @samp{1000}. When using @samp{Rel}
-relocations, that addend must be stored in the instructions themselves.
-If you are adding support for a RISC chip which uses two or more
-instructions to load an address, then the addend may not fit in a single
-instruction, and will have to be somehow split among the instructions.
-This makes linking awkward, particularly when doing a relocateable link
-in which the addend may have to be updated. It can be done---the MIPS
-ELF support does it---but it should be avoided when possible.
-
-It is possible, though somewhat awkward, to support both @samp{Rel} and
-@samp{Rela} relocations for a single target; @file{elf64-mips.c} does it
-by overriding the relocation reading and writing routines.
-@item
-Define howto structures for all the relocation types.
-@item
-Define a @samp{bfd_reloc_type_lookup} routine. This must be named
-@samp{bfd_elf@var{nn}_bfd_reloc_type_lookup}, and may be either a
-function or a macro. It must translate a BFD relocation code into a
-howto structure. This is normally a table lookup or a simple switch.
-@item
-If using @samp{Rel} relocations, define @samp{elf_info_to_howto_rel}.
-If using @samp{Rela} relocations, define @samp{elf_info_to_howto}.
-Either way, this is a macro defined as the name of a function which
-takes an @samp{arelent} and a @samp{Rel} or @samp{Rela} structure, and
-sets the @samp{howto} field of the @samp{arelent} based on the
-@samp{Rel} or @samp{Rela} structure. This is normally uses
-@samp{ELF@var{nn}_R_TYPE} to get the ELF relocation type and uses it as
-an index into a table of howto structures.
-@end itemize
-
-You must also add the magic number for this processor to the
-@samp{prep_headers} function in @file{elf.c}.
-
-You must also create a header file in the @file{include/elf} directory
-called @file{@var{cpu}.h}. This file should define any target specific
-information which may be needed outside of the BFD code. In particular
-it should use the @samp{START_RELOC_NUMBERS}, @samp{RELOC_NUMBER},
-@samp{FAKE_RELOC}, @samp{EMPTY_RELOC} and @samp{END_RELOC_NUMBERS}
-macros to create a table mapping the number used to indentify a
-relocation to a name describing that relocation.
-
-@node BFD ELF processor linker
-@subsubsection Processor specific linker support
-
-The linker will be much more efficient if you define a relocate section
-function. This will permit BFD to use the ELF specific linker support.
-
-If you do not define a relocate section function, BFD must use the
-generic linker support, which requires converting all symbols and
-relocations into BFD @samp{asymbol} and @samp{arelent} structures. In
-this case, relocations will be handled by calling
-@samp{bfd_perform_relocation}, which will use the howto structures you
-have defined. @xref{BFD relocation handling}.
-
-In order to support linking into a different object file format, such as
-S-records, @samp{bfd_perform_relocation} must work correctly with your
-howto structures, so you can't skip that step. However, if you define
-the relocate section function, then in the normal case of linking into
-an ELF file the linker will not need to convert symbols and relocations,
-and will be much more efficient.
-
-To use a relocation section function, define the macro
-@samp{elf_backend_relocate_section} as the name of a function which will
-take the contents of a section, as well as relocation, symbol, and other
-information, and modify the section contents according to the relocation
-information. In simple cases, this is little more than a loop over the
-relocations which computes the value of each relocation and calls
-@samp{_bfd_final_link_relocate}. The function must check for a
-relocateable link, and in that case normally needs to do nothing other
-than adjust the addend for relocations against a section symbol.
-
-The complex cases generally have to do with dynamic linker support. GOT
-and PLT relocations must be handled specially, and the linker normally
-arranges to set up the GOT and PLT sections while handling relocations.
-When generating a shared library, random relocations must normally be
-copied into the shared library, or converted to RELATIVE relocations
-when possible.
-
-@node BFD ELF processor other
-@subsubsection Other processor specific support options
-
-There are many other macros which may be defined in
-@file{elf@var{nn}-@var{cpu}.c}. These macros may be found in
-@file{elfxx-target.h}.
-
-Macros may be used to override some of the generic ELF target vector
-functions.
-
-Several processor specific hook functions which may be defined as
-macros. These functions are found as function pointers in the
-@samp{elf_backend_data} structure defined in @file{elf-bfd.h}. In
-general, a hook function is set by defining a macro
-@samp{elf_backend_@var{name}}.
-
-There are a few processor specific constants which may also be defined.
-These are again found in the @samp{elf_backend_data} structure.
-
-I will not define the various functions and constants here; see the
-comments in @file{elf-bfd.h}.
-
-Normally any odd characteristic of a particular ELF processor is handled
-via a hook function. For example, the special @samp{SHN_MIPS_SCOMMON}
-section number found in MIPS ELF is handled via the hooks
-@samp{section_from_bfd_section}, @samp{symbol_processing},
-@samp{add_symbol_hook}, and @samp{output_symbol_hook}.
-
-Dynamic linking support, which involves processor specific relocations
-requiring special handling, is also implemented via hook functions.
-
-@node BFD ELF core files
-@subsection BFD ELF core files
-@cindex elf core files
-
-On native ELF Unix systems, core files are generated without any
-sections. Instead, they only have program segments.
-
-When BFD is used to read an ELF core file, the BFD sections will
-actually represent program segments. Since ELF program segments do not
-have names, BFD will invent names like @samp{segment@var{n}} where
-@var{n} is a number.
-
-A single ELF program segment may include both an initialized part and an
-uninitialized part. The size of the initialized part is given by the
-@samp{p_filesz} field. The total size of the segment is given by the
-@samp{p_memsz} field. If @samp{p_memsz} is larger than @samp{p_filesz},
-then the extra space is uninitialized, or, more precisely, initialized
-to zero.
-
-BFD will represent such a program segment as two different sections.
-The first, named @samp{segment@var{n}a}, will represent the initialized
-part of the program segment. The second, named @samp{segment@var{n}b},
-will represent the uninitialized part.
-
-ELF core files store special information such as register values in
-program segments with the type @samp{PT_NOTE}. BFD will attempt to
-interpret the information in these segments, and will create additional
-sections holding the information. Some of this interpretation requires
-information found in the host header file @file{sys/procfs.h}, and so
-will only work when BFD is built on a native system.
-
-BFD does not currently provide any way to create an ELF core file. In
-general, BFD does not provide a way to create core files. The way to
-implement this would be to write @samp{bfd_set_format} and
-@samp{bfd_write_contents} routines for the @samp{bfd_core} type; see
-@ref{BFD target vector format}.
-
-@node BFD ELF future
-@subsection BFD ELF future
-
-The current dynamic linking support has too much code duplication.
-While each processor has particular differences, much of the dynamic
-linking support is quite similar for each processor. The GOT and PLT
-are handled in fairly similar ways, the details of -Bsymbolic linking
-are generally similar, etc. This code should be reworked to use more
-generic functions, eliminating the duplication.
-
-Similarly, the relocation handling has too much duplication. Many of
-the @samp{reloc_type_lookup} and @samp{info_to_howto} functions are
-quite similar. The relocate section functions are also often quite
-similar, both in the standard linker handling and the dynamic linker
-handling. Many of the COFF processor specific backends share a single
-relocate section function (@samp{_bfd_coff_generic_relocate_section}),
-and it should be possible to do something like this for the ELF targets
-as well.
-
-The appearance of the processor specific magic number in
-@samp{prep_headers} in @file{elf.c} is somewhat bogus. It should be
-possible to add support for a new processor without changing the generic
-support.
-
-The processor function hooks and constants are ad hoc and need better
-documentation.
-
-When a linker script uses @samp{SIZEOF_HEADERS}, the ELF backend must
-guess at the number of program segments which will be required, in
-@samp{get_program_header_size}. This is because the linker calls
-@samp{bfd_sizeof_headers} before it knows all the section addresses and
-sizes. The ELF backend may later discover, when creating program
-segments, that more program segments are required. This is currently
-reported as an error in @samp{assign_file_positions_for_segments}.
-
-In practice this makes it difficult to use @samp{SIZEOF_HEADERS} except
-with a carefully defined linker script. Unfortunately,
-@samp{SIZEOF_HEADERS} is required for fast program loading on a native
-system, since it permits the initial code section to appear on the same
-page as the program segments, saving a page read when the program starts
-running. Fortunately, native systems permit careful definition of the
-linker script. Still, ideally it would be possible to use relaxation to
-compute the number of program segments.

-@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.
-
-@menu

-* Canonical format:: The BFD canonical object-file format
-@end menu
-
-@node BFD information loss
-@subsection Information Loss
-
-@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).

- list of procedure descriptors (PDR). The address in the FDR
- is the absolute address of the first procedure. The address
- in the first PDR gives the offset of that procedure relative
- to the object file's base-address. The addresses in
- subsequent PDRs specify each procedure's address relative to
- the object file's base-address. To make things more juicy,
- whenever the PROF bit in the PDR is set, the real entry point
- of the procedure may be 16 bytes below what would normally be
- the procedure's entry point. Instead, DEC came up with a
- wicked scheme to create profiled libraries "on the fly":
- instead of shipping a regular and a profiled version of each
- library, they insert 16 bytes of unused space in front of
- each procedure and set the "prof" bit in the PDR to indicate
- that there is a gap there (this is done automagically by "as"
- when option "-pg" is specified). Thus, normally, you link
- against such a library and, except for lots of 16 byte gaps
- between functions, things will behave as usual. However,
- when invoking "ld" with option "-pg", it will fill those gaps
- with code that calls mcount(). It then moves the function's
- entry point down by 16 bytes, and out pops a binary that has
- all functions profiled.
-
- NOTE: Neither FDRs nor PDRs are strictly sorted in memory
- order. For example, when including header-files that
- define functions, the FDRs follow behind the including
- file, even though their code may have been generated at
- a lower address. File coff-alpha.c from libbfd
- illustrates this (use "odump -PFv" to look at a file's
- FDR/PDR). Similarly, PDRs are sometimes out of order
- as well. An example of this is OSF/1 v3.0 libc's
- malloc.c. I'm not sure why this happens, but it could
- be due to optimizations that reorder a function's
- position within an object-file.
-
- Strategy:
-
- On the first call to this function, we build a table of FDRs
- that is sorted by the base-address of the object-file the FDR
- is referring to. Notice that each object-file may contain
- code from multiple source files (e.g., due to code defined in
- include files). Thus, for any given base-address, there may
- be multiple FDRs (but this case is, fortunately, uncommon).
- lookup(addr) guarantees to return the first FDR that applies
- to address ADDR. Thus, after invoking lookup(), we have a
- list of FDRs that may contain the PDR for ADDR. Next, we
- walk through the PDRs of these FDRs and locate the one that
- is closest to ADDR (i.e., for which the difference between
- ADDR and the PDR's entry point is positive and minimal).
- Once, the right FDR and PDR are located, we simply walk
- through the line-number table to lookup the line-number that
- best matches ADDR. Obviously, things could be sped up by
- keeping a sorted list of PDRs instead of a sorted list of
- FDRs. However, this would increase space requirements
- considerably, which is undesirable. */

- stored in the associated HI16S reloc. So for example, these
- relocations:
-
- movhi hi( fred ), r0, r1
- movea lo( fred ), r1, r1
-
- will store 0 in the value fields for the MOVHI and MOVEA instructions

-
- movhi hi( fred + 0x123456), r0, r1
- movea lo( fred + 0x123456), r1, r1
-
- the value stored in the MOVHI instruction will be 0x12 and the value
- stored in the MOVEA instruction will be 0x3456. If however the
- instructions were:
-
- movhi hi( fred + 0x10ffff), r0, r1
- movea lo( fred + 0x10ffff), r1, r1
-
- then the value stored in the MOVHI instruction would be 0x11 (not
- 0x10) and the value stored in the MOVEA instruction would be 0xffff.
- Thus (assuming for the moment that the addend is 0), at run time the
- MOVHI instruction loads 0x110000 into r1, then the MOVEA instruction
- adds 0xffffffff (sign extension!) producing 0x10ffff. Similarly if
- the instructions were:
-
- movhi hi( fred - 1), r0, r1
- movea lo( fred - 1), r1, r1
-
- then 0 is stored in the MOVHI instruction and -1 is stored in the
- MOVEA instruction.
-
- Overflow can occur if the addition of the value stored in the
- instruction plus the addend sets the 15th bit when before it was clear.
- This is because the 15th bit will be sign extended into the high part,
- thus reducing its value by one, but since the 15th bit was originally
- clear, the assembler will not have added 1 to the previous HI16S reloc
- to compensate for this effect. For example:
-
- movhi hi( fred + 0x123456), r0, r1
- movea lo( fred + 0x123456), r1, r1
-
- The value stored in HI16S reloc is 0x12, the value stored in the LO16
- reloc is 0x3456. If we assume that the address of fred is 0x00007000
- then the relocations become:
-
- HI16S: 0x0012 + (0x00007000 >> 16) = 0x12
- LO16: 0x3456 + (0x00007000 & 0xffff) = 0xa456
-
- but when the instructions are executed, the MOVEA instruction's value
- is signed extended, so the sum becomes:
-
- 0x00120000
- + 0xffffa456
- ------------
- 0x0011a456 but 'fred + 0x123456' = 0x0012a456
-
- Note that if the 15th bit was set in the value stored in the LO16
- reloc, then we do not have to do anything:
-
- movhi hi( fred + 0x10ffff), r0, r1
- movea lo( fred + 0x10ffff), r1, r1
-
- HI16S: 0x0011 + (0x00007000 >> 16) = 0x11
- LO16: 0xffff + (0x00007000 & 0xffff) = 0x6fff
-
- 0x00110000
- + 0x00006fff
- ------------
- 0x00116fff = fred + 0x10ffff = 0x7000 + 0x10ffff
-
-
- Overflow can also occur if the computation carries into the 16th bit
- and it also results in the 15th bit having the same value as the 15th
- bit of the original value. What happens is that the HI16S reloc
- will have already examined the 15th bit of the original value and
- added 1 to the high part if the bit is set. This compensates for the
- sign extension of 15th bit of the result of the computation. But now
- there is a carry into the 16th bit, and this has not been allowed for.
-
- So, for example if fred is at address 0xf000:
-
- movhi hi( fred + 0xffff), r0, r1 [bit 15 of the offset is set]
- movea lo( fred + 0xffff), r1, r1
-
- HI16S: 0x0001 + (0x0000f000 >> 16) = 0x0001
- LO16: 0xffff + (0x0000f000 & 0xffff) = 0xefff (carry into bit 16 is lost)
-
- 0x00010000
- + 0xffffefff
- ------------
- 0x0000efff but 'fred + 0xffff' = 0x0001efff
-
- Similarly, if the 15th bit remains clear, but overflow occurs into
- the 16th bit then (assuming the address of fred is 0xf000):
-
- movhi hi( fred + 0x7000), r0, r1 [bit 15 of the offset is clear]
- movea lo( fred + 0x7000), r1, r1
-
- HI16S: 0x0000 + (0x0000f000 >> 16) = 0x0000
- LO16: 0x7000 + (0x0000f000 & 0xffff) = 0x6fff (carry into bit 16 is lost)
-
- 0x00000000
- + 0x00006fff
- ------------
- 0x00006fff but 'fred + 0x7000' = 0x00016fff
-
- Note - there is no need to change anything if a carry occurs, and the
- 15th bit changes its value from being set to being clear, as the HI16S
- reloc will have already added in 1 to the high part for us:
-
- movhi hi( fred + 0xffff), r0, r1 [bit 15 of the offset is set]
- movea lo( fred + 0xffff), r1, r1
-
- HI16S: 0x0001 + (0x00007000 >> 16)
- LO16: 0xffff + (0x00007000 & 0xffff) = 0x6fff (carry into bit 16 is lost)
-
- 0x00010000
- + 0x00006fff (bit 15 not set, so the top half is zero)
- ------------
- 0x00016fff which is right (assuming that fred is at 0x7000)
-
- but if the 15th bit goes from being clear to being set, then we must
- once again handle overflow:
-
- movhi hi( fred + 0x7000), r0, r1 [bit 15 of the offset is clear]
- movea lo( fred + 0x7000), r1, r1
-
- HI16S: 0x0000 + (0x0000ffff >> 16)
- LO16: 0x7000 + (0x0000ffff & 0xffff) = 0x6fff (carry into bit 16)
-
- 0x00000000
- + 0x00006fff (bit 15 not set, so the top half is zero)
- ------------
- 0x00006fff which is wrong (assuming that fred is at 0xffff)

- Written by Fred Fish @ Cygnus Support, from information published
- in "UNIX System V Release 4, Programmers Guide: ANSI C and

-
- Rewritten by Mark Eichin @ Cygnus Support, from information
- published in "System V Application Binary Interface", chapters 4
- and 5, as well as the various "Processor Supplement" documents
- derived from it. Added support for assembler and other object file
- utilities. Further work done by Ken Raeburn (Cygnus Support), Michael
- Meissner (Open Software Foundation), and Peter Hoogenboom (University

-/* Problems and other issues to resolve.
-
- (1) BFD expects there to be some fixed number of "sections" in
- the object file. I.E. there is a "section_count" variable in the
- bfd structure which contains the number of sections. However, ELF
- supports multiple "views" of a file. In particular, with current
- implementations, executable files typically have two tables, a
- program header table and a section header table, both of which
- partition the executable.
-
- In ELF-speak, the "linking view" of the file uses the section header
- table to access "sections" within the file, and the "execution view"
- uses the program header table to access "segments" within the file.
- "Segments" typically may contain all the data from one or more
- "sections".
-
- Note that the section header table is optional in ELF executables,
- but it is this information that is most useful to gdb. If the
- section header table is missing, then gdb should probably try
- to make do with the program header table. (FIXME)
-
- (2) The code in this file is compiled twice, once in 32-bit mode and
- once in 64-bit mode. More of it should be made size-independent
- and moved into elf.c.
-
- (3) ELF section symbols are handled rather sloppily now. This should
- be cleaned up, and ELF section symbols reconciled with BFD section
- symbols.
-
- (4) We need a published spec for 64-bit ELF. We've got some stuff here
- that we're using for SPARC V9 64-bit chips, but don't assume that
- it's cast in stone.

- don't use _bfd_generic_link_add_archive_symbols because of a
- problem which arises on UnixWare. The UnixWare libc.so is an
- archive which includes an entry libc.so.1 which defines a bunch of
- symbols. The libc.so archive also includes a number of other
- object files, which also define symbols, some of which are the same
- as those defined in libc.so.1. Correct linking requires that we
- consider each object file in turn, and include it if it defines any
- symbols we need. _bfd_generic_link_add_archive_symbols does not do
- this; it looks through the list of undefined symbols, and includes
- any object file which defines them. When this algorithm is used on
- UnixWare, it winds up pulling in libc.so.1 early and defining a
- bunch of symbols. This means that some of the other objects in the
- archive are not included in the link, which is incorrect since they
- precede libc.so.1 in the archive.
-
- Fortunately, ELF archive handling is simpler than that done by
- _bfd_generic_link_add_archive_symbols, which has to allow for a.out
- oddities. In ELF, if we find a symbol in the archive map, and the
- symbol is currently undefined, we know that we must pull in that

- int main () { tzset (); printf ("%d %d\n", timezone, _timezone); }
- you might expect that, since timezone is a synonym for _timezone,
- the same number will print both times. However, if the processor
- backend uses a COPY reloc, then actually timezone will be copied

-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.

-SYNOPSIS

-
-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.

- 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>>.

-@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 objalloc which will be
- used to allocate new entries. You may allocate memory on this
- objalloc 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.

-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 objalloc 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.

-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.

-
-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.

- hpux w/gnu extension ----> | |
-
-
- Support for the 9000/[34]00 has several limitations.
- 1. Shared libraries are not supported.
- 2. The output format from this bfd is not usable by native tools.
-
- The primary motivation for writing this bfd was to allow use of
- gdb and gcc for host based debugging and not to mimic the hp-ux tools
- in every detail. This leads to a significant simplification of the
- code and a leap in performance. The decision to not output hp native
- compatible objects was further strengthened by the fact that the richness
- of the gcc compiled objects could not be represented without loss of
- information. For example, while the hp format supports the concept of
- secondary symbols, it does not support indirect symbols. Another
- reason is to maintain backwards compatibility with older implementations
- of gcc on hpux which used 'hpxt' to translate .a and .o files into a
- format which could be readily understood by the gnu linker and gdb.
- This allows reading hp secondary symbols and converting them into
- indirect symbols but the reverse it not always possible.
-
- Another example of differences is that the hp format stores symbol offsets
- in the object code while the gnu utilities use a field in the
- relocation record for this. To support the hp native format, the object
- code would need to be patched with the offsets when producing .o files.
-
- The basic technique taken in this implementation is to #include the code
- from aoutx.h and aout-target.h with appropriate #defines to override
- code where a unique implementation is needed:
-
- {
- #define a bunch of stuff
- #include <aoutx.h>
-
- implement a bunch of functions
-
- #include "aout-target.h"
- }
-
- The hp symbol table is a bit different than other a.out targets. Instead
- of having an array of nlist items and an array of strings, hp's format
- has them mixed together in one structure. In addition, the strings are
- not null terminated. It looks something like this:
-
- nlist element 1
- string1
- nlist element 2
- string2
- ...
-
- The whole symbol table is read as one chunk and then we march thru it
- and convert it to canonical form. As we march thru the table, we copy
- the nlist data into the internal form and we compact the strings and null
- terminate them, using storage from the already allocated symbol table:
-
- string1
- null
- string2
- null
- */
-
-/* @@ Is this really so different from normal a.out that it needs to include
- aoutx.h? We should go through this file sometime and see what can be made
- more dependent on aout32.o and what might need to be broken off and accessed
- through the backend_data field. Or, maybe we really do need such a
- completely separate implementation. I don't have time to investigate this
- much further right now. [raeburn:19930428.2124EST] */
-/* @@ Also, note that there wind up being two versions of some routines, with
- different names, only one of which actually gets used. For example:
- slurp_symbol_table
- swap_std_reloc_in
- slurp_reloc_table
- get_symtab
- get_symtab_upper_bound
- canonicalize_reloc
- mkobject

-/* This is what Intel Hex files look like:
-
-1. INTEL FORMATS
-
-A. Intel 1
-
- 16-bit address-field format, for files 64k bytes in length or less.
-
- DATA RECORD
- Byte 1 Header = colon(:)
- 2..3 The number of data bytes in hex notation
- 4..5 High byte of the record load address
- 6..7 Low byte of the record load address
- 8..9 Record type, must be "00"
- 10..x Data bytes in hex notation:
- x = (number of bytes - 1) * 2 + 11
- x+1..x+2 Checksum in hex notation
- x+3..x+4 Carriage return, line feed
-
- END RECORD
- Byte 1 Header = colon (:)
- 2..3 The byte count, must be "00"
- 4..7 Transfer-address (usually "0000")
- the jump-to address, execution start address
- 8..9 Record type, must be "01"
- 10..11 Checksum, in hex notation
- 12..13 Carriage return, line feed
-
-B. INTEL 2
-
- MCS-86 format, using a 20-bit address for files larger than 64K bytes.
-
- DATA RECORD
- Byte 1 Header = colon (:)
- 2..3 The byte count of this record, hex notation
- 4..5 High byte of the record load address
- 6..7 Low byte of the record load address
- 8..9 Record type, must be "00"
- 10..x The data bytes in hex notation:
- x = (number of data bytes - 1) * 2 + 11
- x+1..x+2 Checksum in hex notation
- x+3..x+4 Carriage return, line feed
-
- EXTENDED ADDRESS RECORD
- Byte 1 Header = colon(:)
- 2..3 The byte count, must be "02"
- 4..7 Load address, must be "0000"
- 8..9 Record type, must be "02"
- 10..11 High byte of the offset address
- 12..13 Low byte of the offset address
- 14..15 Checksum in hex notation
- 16..17 Carriage return, line feed
-
- The checksums are the two's complement of the 8-bit sum
- without carry of the byte count, offset address, and the
- record type.

-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, @file{libaout.h} defines <<GET_WORD>>
- to either <<bfd_get_32>> or <<bfd_get_64>>.
-
- In the put routines, @var{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.

-SECTION
- Linker Functions
-
-@cindex Linker
- 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.

- Creating a linker hash table
-
-@cindex _bfd_link_hash_table_create in target vector
-@cindex target vector (_bfd_link_hash_table_create)
- The linker routines must create a hash table, which must be
- derived from <<struct bfd_link_hash_table>> described in
- <<bfdlink.c>>. @xref{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 relocateable
- 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.

- the hash table. For an archive, BFD must determine which
- elements of the archive should be used and adding them to the

-SUBSUBSECTION
- 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 <<creator>>
- field of the hash table 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 <<creator>> field before saving information (in this
- case, the ECOFF external symbol debugging information) in a
- hash table entry.
-
-INODE
-Adding symbols from an object file, Adding symbols from an archive, Differing file formats, Adding Symbols to the Hash Table
-SUBSUBSECTION
- 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.
-
-@findex _bfd_generic_link_add_one_symbol
- <<_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.
-
-INODE
-Adding symbols from an archive, , Adding symbols from an object file, Adding Symbols to the Hash Table
-SUBSUBSECTION
- 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.
-
-@findex _bfd_generic_link_add_archive_symbols
- 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 elements symbols must be added to the linker hash table
- just as though the element had itself been passed to the
- <<_bfd_link_add_symbols>> function.
-
- When the a.out <<_bfd_link_add_symbols>> function receives an
- archive, it calls <<_bfd_generic_link_add_archive_symbols>>
- passing <<aout_link_check_archive_element>> as the function
- argument. <<aout_link_check_archive_element>> calls
- <<aout_link_check_ar_symbols>>. If the latter decides to add
- the element (an element is only added if it provides a real,
- non-common, definition for a previously undefined or common
- symbol) it calls the <<add_archive_element>> callback and then
- <<aout_link_check_archive_element>> calls
- <<aout_link_add_symbols>> to actually add the symbols to the
- linker hash table.
-
- 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.

-@cindex _bfd_link_final_link in target vector

- 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 relocateable 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)>>.

- 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 <<link_order_head>>
- 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 relocateable object file.

-Relocating the section contents, Writing the symbol table, Information provided by the linker, Performing the Final Link
-SUBSUBSECTION
- 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 relocateable link, the
- relocs themselves must also be modified and written out.
-
-@findex _bfd_relocate_contents
-@findex _bfd_final_link_relocate
- 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>>.

-Writing the symbol table, , Relocating the section contents, Performing the Final Link
-SUBSUBSECTION
- 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)>>.

-
- 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.

-Most of this hacked by Steve Chamberlain,
- sac@cygnus.com
-*/
-
-/* Hey look, some documentation [and in a place you expect to find it]!
-
- The main reference for the pei format is "Microsoft Portable Executable
- and Common Object File Format Specification 4.1". Get it if you need to
- do some serious hacking on this code.
-
- Another reference:
- "Peering Inside the PE: A Tour of the Win32 Portable Executable
- File Format", MSJ 1994, Volume 9.
-
- The *sole* difference between the pe format and the pei format is that the
- latter has an MSDOS 2.0 .exe header on the front that prints the message
- "This app must be run under Windows." (or some such).
- (FIXME: Whether that statement is *really* true or not is unknown.
- Are there more subtle differences between pe and pei formats?
- For now assume there aren't. If you find one, then for God sakes
- document it here!)
-
- The Microsoft docs use the word "image" instead of "executable" because
- the former can also refer to a DLL (shared library). Confusion can arise
- because the `i' in `pei' also refers to "image". The `pe' format can
- also create images (i.e. executables), it's just that to run on a win32
- system you need to use the pei format.
-
- FIXME: Please add more docs here so the next poor fool that has to hack
- on this code has a chance of getting something accomplished without
- wasting too much time.

-
- 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. */

-DESCRIPTION
-
- Here is a description of each of the fields within an <<arelent>>:
-
- o <<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
- <<get_symtab>> action. @xref{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.
-
- o <<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.
-
- o <<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:

- 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:
-
-

-|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.

-
- Both relocs contain a pointer to <<foo>>, and the offsets

-
- 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.

-which explains why it is still enabled: --djm
-
-If you put a patch like that into BFD you need to check all the COFF
-linkers. I am fairly certain that patch will break coff-i386 (e.g.,
-SCO); see coff_i386_reloc in coff-i386.c where I worked around the
-problem in a different way. There may very well be a reason that the
-code works as it does.
-
-Hmmm. The first obvious point is that bfd_perform_relocation should
-not have any tests that depend upon the flavour. It's seem like
-entirely the wrong place for such a thing. The second obvious point
-is that the current code ignores the reloc addend when producing
-relocateable output for COFF. That's peculiar. In fact, I really
-have no idea what the point of the line you want to remove is.
-
-A typical COFF reloc subtracts the old value of the symbol and adds in
-the new value to the location in the object file (if it's a pc
-relative reloc it adds the difference between the symbol value and the
-location). When relocating we need to preserve that property.
-
-BFD handles this by setting the addend to the negative of the old
-value of the symbol. Unfortunately it handles common symbols in a
-non-standard way (it doesn't subtract the old value) but that's a
-different story (we can't change it without losing backward
-compatibility with old object files) (coff-i386 does subtract the old
-value, to be compatible with existing coff-i386 targets, like SCO).
-
-So everything works fine when not producing relocateable output. When
-we are producing relocateable output, logically we should do exactly
-what we do when not producing relocateable output. Therefore, your
-patch is correct. In fact, it should probably always just set
-reloc_entry->addend to 0 for all cases, since it is, in fact, going to
-add the value into the object file. This won't hurt the COFF code,
-which doesn't use the addend; I'm not sure what it will do to other
-formats (the thing to check for would be whether any formats both use
-the addend and set partial_inplace).
-
-When I wanted to make coff-i386 produce relocateable output, I ran
-into the problem that you are running into: I wanted to remove that
-line. Rather than risk it, I made the coff-i386 relocs use a special
-function; it's coff_i386_reloc in coff-i386.c. The function
-specifically adds the addend field into the object file, knowing that
-bfd_perform_relocation is not going to. If you remove that line, then
-coff-i386.c will wind up adding the addend field in twice. It's
-trivial to fix; it just needs to be done.
-
-The problem with removing the line is just that it may break some
-working code. With BFD it's hard to be sure of anything. The right
-way to deal with this is simply to build and test at least all the
-supported COFF targets. It should be straightforward if time and disk
-space consuming. For each target:
- 1) build the linker
- 2) generate some executable, and link it using -r (I would
- probably use paranoia.o and link against newlib/libc.a, which
- for all the supported targets would be available in
- /usr/cygnus/progressive/H-host/target/lib/libc.a).
- 3) make the change to reloc.c
- 4) rebuild the linker
- 5) repeat step 2
- 6) if the resulting object files are the same, you have at least
- made it no worse
- 7) if they are different you have to figure out which version is
- right

-SYNOPSIS
- bfd_reloc_status_type
- bfd_install_relocation
- (bfd *abfd,
- arelent *reloc_entry,
- PTR 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.

-
-However, Ian wrote the following, regarding removing the line below,
-which explains why it is still enabled: --djm
-
-If you put a patch like that into BFD you need to check all the COFF
-linkers. I am fairly certain that patch will break coff-i386 (e.g.,
-SCO); see coff_i386_reloc in coff-i386.c where I worked around the
-problem in a different way. There may very well be a reason that the
-code works as it does.
-
-Hmmm. The first obvious point is that bfd_install_relocation should
-not have any tests that depend upon the flavour. It's seem like
-entirely the wrong place for such a thing. The second obvious point
-is that the current code ignores the reloc addend when producing
-relocateable output for COFF. That's peculiar. In fact, I really
-have no idea what the point of the line you want to remove is.
-
-A typical COFF reloc subtracts the old value of the symbol and adds in
-the new value to the location in the object file (if it's a pc
-relative reloc it adds the difference between the symbol value and the
-location). When relocating we need to preserve that property.
-
-BFD handles this by setting the addend to the negative of the old
-value of the symbol. Unfortunately it handles common symbols in a
-non-standard way (it doesn't subtract the old value) but that's a
-different story (we can't change it without losing backward
-compatibility with old object files) (coff-i386 does subtract the old
-value, to be compatible with existing coff-i386 targets, like SCO).
-
-So everything works fine when not producing relocateable output. When
-we are producing relocateable output, logically we should do exactly
-what we do when not producing relocateable output. Therefore, your
-patch is correct. In fact, it should probably always just set
-reloc_entry->addend to 0 for all cases, since it is, in fact, going to
-add the value into the object file. This won't hurt the COFF code,
-which doesn't use the addend; I'm not sure what it will do to other
-formats (the thing to check for would be whether any formats both use
-the addend and set partial_inplace).
-
-When I wanted to make coff-i386 produce relocateable output, I ran
-into the problem that you are running into: I wanted to remove that
-line. Rather than risk it, I made the coff-i386 relocs use a special
-function; it's coff_i386_reloc in coff-i386.c. The function
-specifically adds the addend field into the object file, knowing that
-bfd_install_relocation is not going to. If you remove that line, then
-coff-i386.c will wind up adding the addend field in twice. It's
-trivial to fix; it just needs to be done.
-
-The problem with removing the line is just that it may break some
-working code. With BFD it's hard to be sure of anything. The right
-way to deal with this is simply to build and test at least all the
-supported COFF targets. It should be straightforward if time and disk
-space consuming. For each target:
- 1) build the linker
- 2) generate some executable, and link it using -r (I would
- probably use paranoia.o and link against newlib/libc.a, which
- for all the supported targets would be available in
- /usr/cygnus/progressive/H-host/target/lib/libc.a).
- 3) make the change to reloc.c
- 4) rebuild the linker
- 5) repeat step 2
- 6) if the resulting object files are the same, you have at least
- made it no worse
- 7) if they are different you have to figure out which version is
- right

-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.

- 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).
-ENUM
- BFD_RELOC_ALPHA_GPDISP_LO16
-ENUMDOC
- 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.
-
-ENUM
- BFD_RELOC_ALPHA_GPDISP

- BFD_RELOC_ALPHA_LITUSE
-ENUMDOC
- 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)
-
- The GNU linker currently doesn't do any of this optimizing.
-
-ENUM
- BFD_RELOC_ALPHA_HINT

- BFD_RELOC_VTABLE_ENTRY
-ENUMDOC
- 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 inheritence 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.

-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>>.

-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.
-

-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.

-/* About the relocation formatting table...
-
- There are 256 entries in the table, one for each possible
- relocation opcode available in SOM. We index the table by
- the relocation opcode. The names and operations are those
- defined by a.out_800 (4).
-
- Right now this table is only used to count and perform minimal
- processing on relocation streams so that they can be internalized
- into BFD and symbolically printed by utilities. To make actual use
- of them would be much more difficult, BFD's concept of relocations
- is far too simple to handle SOM relocations. The basic assumption
- that a relocation can be completely processed independent of other
- relocations before an object file is written is invalid for SOM.
-
- The SOM relocations are meant to be processed as a stream, they
- specify copying of data from the input section to the output section
- while possibly modifying the data in some manner. They also can
- specify that a variable number of zeros or uninitialized data be
- inserted on in the output segment at the current offset. Some
- relocations specify that some previous relocation be re-applied at
- the current location in the input/output sections. And finally a number
- of relocations have effects on other sections (R_ENTRY, R_EXIT,
- R_UNWIND_AUX and a variety of others). There isn't even enough room
- in the BFD relocation data structure to store enough information to
- perform all the relocations.
-
- Each entry in the table has three fields.
-
- The first entry is an index into this "class" of relocations. This
- index can then be used as a variable within the relocation itself.
-
- The second field is a format string which actually controls processing
- of the relocation. It uses a simple postfix machine to do calculations
- based on variables/constants found in the string and the relocation
- stream.
-
- The third field specifys whether or not this relocation may use
- a constant (V) from the previous R_DATA_OVERRIDE rather than a constant
- stored in the instruction.
-
- Variables:
-
- L = input space byte count
- D = index into class of relocations
- M = output space byte count
- N = statement number (unused?)
- O = stack operation
- R = parameter relocation bits
- S = symbol index
- T = first 32 bits of stack unwind information
- U = second 32 bits of stack unwind information
- V = a literal constant (usually used in the next relocation)
- P = a previous relocation
-
- Lower case letters (starting with 'b') refer to following
- bytes in the relocation stream. 'b' is the next 1 byte,
- c is the next 2 bytes, d is the next 3 bytes, etc...
- This is the variable part of the relocation entries that
- makes our life a living hell.
-
- numerical constants are also used in the format string. Note
- the constants are represented in decimal.
-
- '+', "*" and "=" represents the obvious postfix operators.
- '<' represents a left shift.
-
- Stack Operations:
-
- Parameter Relocation Bits:
-
- Unwind Entries:
-
- Previous Relocations: The index field represents which in the queue
- of 4 previous fixups should be re-applied.
-
- Literal Constants: These are generally used to represent addend
- parts of relocations when these constants are not stored in the
- fields of the instructions themselves. For example the instruction
- addil foo-$global$-0x1234 would use an override for "0x1234" rather
- than storing it into the addil itself. */

-SUBSECTION
- S-Record handling
-
-DESCRIPTION
-
- Ordinary S-Records cannot hold anything but addresses and
- data, so that's all that we implement.
-
- The only interesting thing is that S-Records may come out of
- order and there is no header, so an initial scan is required
- to discover the minimum and maximum addresses used to create
- the vma and size of the only section we create. We
- arbitrarily call this section ".text".
-
- When bfd_get_section_contents is called the file is read
- again, and this time the data is placed into a bfd_alloc'd
- area.
-
- Any number of sections may be created for output, we save them
- up and output them when it's time to close the bfd.
-
- An s record looks like:
-
-EXAMPLE
- S<type><length><address><data><checksum>
-
-DESCRIPTION
- Where
- o length
- is the number of bytes following upto the checksum. Note that
- this is not the number of chars following, since it takes two
- chars to represent a byte.
- o type
- is one of:
- 0) header record
- 1) two byte address data record
- 2) three byte address data record
- 3) four byte address data record
- 7) four byte address termination record
- 8) three byte address termination record
- 9) two byte address termination record
-
- o address
- is the start address of the data following, or in the case of
- a termination record, the start address of the image
- o data
- is the data.
- o checksum
- is the sum of all the raw byte data in the record, from the length
- upwards, modulo 256 and subtracted from 255.
-
-
-SUBSECTION
- Symbol S-Record handling
-
-DESCRIPTION
- Some ICE equipment understands an addition to the standard
- S-Record format; symbols and their addresses can be sent
- before the data.
-
- The format of this is:
- ($$ <modulename>
- (<space> <symbol> <address>)*)
- $$
-
- so a short symbol table could look like:
-
-EXAMPLE
- $$ flash.x
- $$ flash.c
- _port6 $0
- _delay $4
- _start $14
- _etext $8036
- _edata $8036
- _end $8036
- $$
-
-DESCRIPTION
- We allow symbols to be anywhere in the data stream - the module names
- are always ignored.

-SECTION
- 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.

- 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 = (asymbol **) 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.
-
-
-INODE

-SUBSECTION
- 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 "bfd.h"
-| main()

- 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.

-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.

-
-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.

-

-. (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!

-SUBSECTION
- Tektronix Hex Format handling
-
-DESCRIPTION
-
- Tek Hex records can hold symbols and data, but not
- relocations. Their main application is communication with
- devices like PROM programmers and ICE equipment.
-
- It seems that the sections are descibed as being really big,
- the example I have says that the text section is 0..ffffffff.
- BFD would barf with this, many apps would try to alloc 4GB to
- read in the file.
-
- Tex Hex may contain many sections, but the data which comes in
- has no tag saying which section it belongs to, so we create
- one section for each block of data, called "blknnnn" which we
- stick all the data into.
-
- TekHex may come out of order and there is no header, so an
- initial scan is required to discover the minimum and maximum
- addresses used to create the vma and size of the sections we
- create.
- We read in the data into pages of CHUNK_MASK+1 size and read
- them out from that whenever we need to.
-
- Any number of sections may be created for output, we save them
- up and output them when it's time to close the bfd.
-
-
- A TekHex record looks like:
-EXAMPLE
- %<block length><type><checksum><stuff><cr>
-
-DESCRIPTION
- Where
- o length
- is the number of bytes in the record not including the % sign.
- o type
- is one of:
- 3) symbol record
- 6) data record
- 8) termination record
-
-
-The data can come out of order, and may be discontigous. This is a
-serial protocol, so big files are unlikely, so we keep a list of 8k chunks

-
- this is a little tricky since it should be portable.
-
- the openVMS object file has 'variable length' which means that
- read() returns data in chunks of (hopefully) correct and expected
- size. The linker (and other tools on vms) depend on that. Unix doesn't
- know about 'formatted' files, so reading and writing such an object
- file in a unix environment is not trivial.
-
- With the tool 'file' (available on all vms ftp sites), one
- can view and change the attributes of a file. Changing from
- 'variable length' to 'fixed length, 512 bytes' reveals the
- record length at the first 2 bytes of every record. The same
- happens during the transfer of object files from vms to unix,
- at least with ucx, dec's implementation of tcp/ip.
-
- The vms format repeats the length at bytes 2 & 3 of every record.
-
- On the first call (file_format == FF_UNKNOWN) we check if
- the first and the third byte pair (!) of the record match.
- If they do it's an object file in an unix environment or with
- wrong attributes (FF_FOREIGN), else we should be in a vms
- environment where read() returns the record size (FF_NATIVE).
-
- reading is always done in 2 steps.
- first just the record header is read and the length extracted
- by get_header_values
- then the read buffer is adjusted and the remaining bytes are
- read in.
