+ GNU GENERAL PUBLIC LICENSE
+ Version 1, February 1989
+
+ Copyright (C) 1989 Free Software Foundation, Inc.
+ 675 Mass Ave, Cambridge, MA 02139, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The license agreements of most software companies try to keep users
+at the mercy of those companies. By contrast, our 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. The
+General Public License applies to the Free Software Foundation's
+software and to any other program whose authors commit to using it.
+You can use it for your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Specifically, the General Public License is designed to make
+sure that you have the freedom to give away or sell copies of free
+software, 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 a 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 tell them 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.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+\f
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement 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 work containing the
+Program or a portion of it, either verbatim or with modifications. Each
+licensee is addressed as "you".
+
+ 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
+General Public License and to the absence of any warranty; and give any
+other recipients of the Program a copy of this General Public License
+along with the Program. You may charge a fee for the physical act of
+transferring a copy.
+
+ 2. You may modify your copy or copies of the Program or any portion of
+it, and copy and distribute such modifications under the terms of Paragraph
+1 above, provided that you also do the following:
+
+ a) cause the modified files to carry prominent notices stating that
+ you changed the files and the date of any change; and
+
+ b) cause the whole of any work that you distribute or publish, that
+ in whole or in part contains the Program or any part thereof, either
+ with or without modifications, to be licensed at no charge to all
+ third parties under the terms of this General Public License (except
+ that you may choose to grant warranty protection to some or all
+ third parties, at your option).
+
+ c) If the modified program normally reads commands interactively when
+ run, you must cause it, when started running for such interactive use
+ in the simplest and most usual 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 General
+ Public License.
+
+ d) 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.
+
+Mere aggregation of another independent work with the Program (or its
+derivative) on a volume of a storage or distribution medium does not bring
+the other work under the scope of these terms.
+\f
+ 3. You may copy and distribute the Program (or a portion or derivative of
+it, under Paragraph 2) in object code or executable form under the terms of
+Paragraphs 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
+ Paragraphs 1 and 2 above; or,
+
+ b) accompany it with a written offer, valid for at least three
+ years, to give any third party free (except for a nominal charge
+ for the cost of distribution) a complete machine-readable copy of the
+ corresponding source code, to be distributed under the terms of
+ Paragraphs 1 and 2 above; or,
+
+ c) accompany it with the information you received as to where the
+ corresponding source code may be obtained. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form alone.)
+
+Source code for a work means the preferred form of the work for making
+modifications to it. For an executable file, complete source code means
+all the source code for all modules it contains; but, as a special
+exception, it need not include source code for modules which are standard
+libraries that accompany the operating system on which the executable
+file runs, or for standard header files or definitions files that
+accompany that operating system.
+
+ 4. You may not copy, modify, sublicense, distribute or transfer the
+Program except as expressly provided under this General Public License.
+Any attempt otherwise to copy, modify, sublicense, distribute or transfer
+the Program is void, and will automatically terminate your rights to use
+the Program under this License. However, parties who have received
+copies, or rights to use copies, from you under this General Public
+License will not have their licenses terminated so long as such parties
+remain in full compliance.
+
+ 5. By copying, distributing or modifying 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.
+
+ 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.
+\f
+ 7. 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 the 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
+the license, you may choose any version ever published by the Free Software
+Foundation.
+
+ 8. 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
+
+ 9. 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.
+
+ 10. 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
+\f
+ Appendix: How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to humanity, 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 1, or (at your option)
+ any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) 19xx 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 a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the
+ program `Gnomovision' (a program to direct compilers to make passes
+ at assemblers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989

+That's all there is to it!

+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
+
+ * sunos.c added architecture stuff for output. Fixed
+ bug where files where vma(data) != size(text)
+ were processed wrong.
+
+ * coff-code.h added a lint cast
+
+ * (../include/a.out.sun4.h) fixed it so zmagic
+ worked
+
+Mon Jan 28 19:15:29 PST 1991 steve@cygnus.com
+
+ * archive.c removed loads of includes, and fixed bug where string
+ table didn't have a null at the end.
+
+ * bfd.c fixed includes, added symbols argument to
+ canonicalize_reloc entry point.
+
+ * libbfd.c fixed includes and added some lint patches.
+
+ * targets.c added both sorts of intel coff.
+
+ * b.out.c fixed included, changed was the canonical
+ relocs were done.
+
+ * icoff.c added support for callj and big and little
+ enidian tables.
+
+ * opncls.c added chmod+xing for files with EXEC_P set.
+
+ * sunos.c fixed includes. Changed default section
+ alignement to words. Fixed relocation stuff to work with
+ new scheme
+
+ * bfd.h various new types added, prototype for new
+ reloc calls, changed bfd->iostream to a void *
+ to including files don't need stdio.h.
+
+ * libcoff.h added conversion table to tie relocs to
+ canonical symbols
+
+ * sysdep.h created
+
+ * coff-code.h fixed includes. Added code to support
+ big and little endian formats. Various lints. Better
+ processing of symbols. Changed reloc stuff to new
+ 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
+ acessor macros. Added bfd_symbol_same_target macro.

+ symbols section relative.
+

+ (bfd_make_section) took out initialization of obsolete members.
+ (bfd_print_symbol_vandf) added
+
+ * opncls.c (bfd_create) created.
+
+ * coff-code.h (coff_new_section_hook) took away refs
+ to obsolete members. (make_a_section_from_file) added
+ 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.
+ (coff_slurp_relocs) fixed for use with new asection shape.
+
+Sat Jan 19 16:10:42 PST 1991 steve@cygnus.com
+
+ * archive.c lots of lint
+
+ * b.out.c added callj relocation support, upgrated reloc howto.
+ Fixed so that asymbol and reloc records are output
+ correctly.
+
+ * bfd.c lots of lint, support for new bfd entry point
+ bfd_print_symbol.
+
+ * bfd.h changed definition of asymbol to contain pointer to
+ owning bfd, removed target dependencies.
+
+ * cache.c took out print statements, put in BFD_ASSERT calls.

+Wed Jan 16 21:38:09 PST 1991 steve@cygnus.com
+
+ * b.out.c removed prototype of sunos4_ennativate_symtab, lots of
+ 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.
+
+ * sunos.c added support for n_other field. Braced the howto table so
+ that it won't be affected by any lengthing of the howto struct typedef.
+ Various lints
+
+ * bfd.h added support for n_other field, added special_function
+ reloc type, modified bfd_perform_relocation prototype. Added bfd_h_get_x
+ macros.
+
+ * bfd.c upgraded bfd_perform_relocation, various lints.
+
+Wed Jan 16 01:55:53 1991 John Gilmore (gnu at rtl)
+
+ * ChangeLog: Started ChangeLog for BFD.

+ icoff.c: change callee.
+ sunos.c (sunos4_object_p, sunos4_core_file_p): change callee.
+
+ * libbfd.c (zalloc): It should actually zero the storage!
+ This was commented out for some reason.
+
+ * libbfd.h: Add malloc, xmalloc, memcpy, and fatal decls.
+ 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
+ noticed the section count for sunos core files was bad, but only
+ GDB had detected the problem.

+Things that still need to be handled: -*- Text -*-
+
+ o - check all the swapping code.
+ o - change the memory usage to reflect the message which follows the
+ page break.
+ o - implement bfd_abort, which should close the bfd but not alter the
+ filesystem.
+ o - remove the following obsolete functions:
+ bfd_symbol_value
+ bfd_symbol_name
+ bfd_get_first_symbol
+ bfd_get_next_symbol
+ bfd_classify_symbol
+ bfd_symbol_hasclass
+ o - update the bfd doc; write a how-to-write-a-backend doc.
+ o - change reloc handling as per Steve's suggestion.
+
+\f
+Changing the way bfd uses memory. The new convention is simple:
+
+ o - bfd will never write into user-supplied memory, nor attempt to
+ free it.
+ o - closing a bfd may reclaim all bfd-allocated memory associated
+ with that bfd.
+ - - bfd_target_list will be the one exception; you must reclaim the
+ returned vector yourself.
+
+Interface implications are minor (get_symcount_upper_bound will go
+away; bfd_cannicalize_symtab will allocate its own memory, etc).
+
+Certain operations consume a lot of memory; for them manual
+reclaimation is available:
+
+ o - bfd_canonicalize_symtab will return a pointer to a
+ null-terminated vector of symbols. Subsequent calls may or may
+ not return the same pointer.
+ bfd_canonicalize_relocs will do the same; returning a pointer to
+ an array of arelocs. Calling this function will read symbols in
+ too.
+
+ o - bfd_reclaim_relocs will free the memory used by these relocs.
+ the symbols will be untouched.
+ bfd_reclaim_symtab (ne bfd_reclaim_symbol_table) will free the
+ memory allocated by canonialize_symtab.
+ Since relocations point to symbols, any relocations obtained by a
+ call to bfd_canonicalize_relocs will be reclaimed as well.
+
+ o - if you don't call the reclaim_ functions, the memory will be
+ reclaimed at bfd_close time.

+ FIXME-SOON. There is a major, potentially invalid assumption in this
+ code. Namely, that incoming symbol tables will be broken up and glued back
+ together but only on C_FILE boundaries. That is, if you break the symbol
+ table on some other boundary, or if you remove a single symbol in the
+ middle, it is possible to end up with garbage where you expect your
+ debugging info to be. This only affects debugging info. Specifically, it
+ affects all of the foondx's in the aux entries. C_FILE entries ARE glued
+ back together properly. Line numbers and relocations are tracked with
+ pointers so their ndx's aren't affected.
+
+On the other hand, if the symbol that a line number or reloc points to goes
+ away, or isn't included in an output bfd, then you'll end up with mush
+ anyway.
+
+I'm not sure at this point, (Sun Mar 3 00:56:11 PST 1991), but I suspect the
+ bfd library will need to provide at least the option of a higher and/or
+ lower abstraction for (at least debugging) symbols. The current
+ abstraction is sufficient for linking, nm, and very nearly for stripping,
+ but is nowhere near what would be needed for gas to create coff symbols or
+ for gdb to read them.

+

+
+ The reason that bfd_openr and bfd_fdopenr exist, yet only bfd_openw
+ exists is because of locking. When we do output, we lock the
+ filename file for output, then open a temporary file which does not
+ actually get its correct filename until closing time. This is
+ safest, but requires the asymmetry in read and write entry points.
+
+ Perhaps, since unix has so many different kinds of locking anyway,
