Readability +is much more important than brevity. + +Any data or function not referenced outside the +defining source file should be declared 'static'. + +Any duplicated code is a candidate for refactoring +into a subprogram. + +Function names should be all lower case with underbars +with the goal that statements and comments 'read well'. + +Variables should be lower-case with +underbars for readability. It's ok for a small loop +with counters to use single letter names like i or k or m. + +Structure members should have a struct-specific +2-character prefix to the name (followed by +an underbar).

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 Lesser 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. + + + Copyright (C) + + 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., + 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 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) year 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. + + , 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.

For non-MIPS objects, the list of register + names in print_sections.c is not appropriate, #define + DWARFDUMP_TURN_OFF_MIPS_REG_NAMES to turn off the MIPS names. +December 1, 2005 + Added new DWARF3 TAGs and ATtributes to the -k lists, + clarified the -k reporting, and made the build more robust + in the face of errors in the *.list relationship-spec-files. + +August 1, 2005 + Now print_die.c deals with long loclists without a coredump. + Added esb.h esb.c (and testesb.c for testing) to encapsulate + getting space for possibly-long strings. + Now print_die.c uses snprintf() not sprintf (hopefully this + will not inconvenience anyone, snprintf() has been available + on most systems for years now). + Altered print of location lists a little bit - for better appearance. + +July 15, 2005 + Now completely frees all allocated memory. Various + routines were not calling dealloc() code and + new libdwarf dealloc routines are now used where those + are needed. + + Now prints DWARF3 .debug_pubtypes section (with -a or -y). + The .debug_pubtypes section and SGI-specific .debug_typenames + are equvalent so they are treated alike. + +Mar 21, 2005 + The -f flag now prints only .debug_frame data. The .eh_frame section + (GNU exceptions data) now prints with -F (not -a). + Printing gcc 3.3 or 3.4 .eh_frame with zR augmentation + does not work at this time, so do not use -F + to print such an object. + The line section print now prints a CU-DIE offset for each such DIEs + line information. This makes it much easier to correctly associate + -l (or -v -l) output with -v -v -l when debugging a faulty + linetable in an executable. + With -v -v -l (two -v) the output of line info continues to be a + completely different format than zero or one -v, the two-v + form showing the detailed line table opcodes. + With g++ 3.3.3 one sees bad line addresses at times as the + DW_LNE_set_address address for header files do not always + get their relocations applied. I am told this is fixed in 3.4.x. + + +Mar 18, 2005 + In correcting printing of macro information the format + of the macro (-m) output has changed substantially. + Much more complete now. Still could use enhancement. + +Oct 28, 2004 + Updated contact address in copyright: SGI moved 1/4 mile + to a new address: 1500 Crittenden Lane. + +Oct 02, 2003 + Now fully supports .debug_loc section. + +June 14, 2001 + Now calling a new function dwarf_get_arange_cu_header_offset() + in libdwarf and printing the returned cu header offset for + aranges entries. Making it easier to track down internal + errors in the dwarf2 data. Also added small other + consistency checks, printing a message and exit()ing on + error. + +April 14, 2000 + The libdwarf copyright has changed to + version 2.1 of the GNU Lesser General Public License. + Anyone holding a version of libdwarf that was published + before this new copyright + is allowed to use + the copyright published in that earlier libdwarf source + on the earlier source + or to use + this new copyright on the earlier source, + at their option. + +July 21, 1999 + Added gnu extensions to the frame information printer + and handling for egcs eh_frame printing. + libdwarf changes mean this now can print little-endian + object dwarf on a big-endian system and vice-versa. + +December, 1998 + added dwarfdump to the dwarf public source distribution. + +June, 1994 + libdwarf consumer interface changed completely so updated to match. + +May, 1993 + Initial version of dwarfdump for dwarf version 2 + written at sgi. diff --git a/dwarfdump/README b/dwarfdump/README new file mode 100644 index 0000000..515e2b6 --- /dev/null +++ b/dwarfdump/README @@ -0,0 +1,82 @@ +I would prefer you try using ../dwarfdump2, not this source. +If you must use this for some reason, could you let me know why? +Thanks. + +To build dwarfdump, first build libdwarf in the neighboring +directory then type + ./configure + make + +Installation is a bit primitive. + sudo make install +may or may not work. +Some or all of the following might be required on Unix or Linux or MacOS: + sudo mkdir -p /usr/local/share/man/man1/ + sudo mkdir -p /usr/local/lib + sudo mkdir -p /usr/local/bin +Then retry the 'sudo make install' and (if necessary) try + sudo chmod a+x /usr/local/bin/dwarfdump + sudo chmod a+r /usr/local/share/man/man1/dwarfdump.1 + sudo chmod a+r /usr/local/lib/dwarfdump.conf +You don't really need the dwarfdump.1 man page, +but you might as well have it.

When errors are encountered +dwarfdump does attempt to print sufficient context so that +one can understand exactly where the error is in the DWARF. +This change makes checking really large object files +much easier. +.PP +The format is intended to be human readable. +If a script is to parse the output, the +.B \-d +option is useful. +.PP +Not all sections actually exist in any given object file. +.PP +The format may change from release to release, so it is +unwise to depend too heavily on the format. +.PP +Frame information (.debug_frame and .eh_frame) is heavily +dependent on the ABI/ISA of the object file. +By default we use a generic set of register names +handling up to 100 registers named r0-100. +The '-R' option uses a built-in generic register name set +handling up to 1200 registers named r0-r1199. +The '-x abi=' +description below shows how to name an abi and use that to guide +the -f or -F processing. +Unless the cpu for the object file being dumped has many registers, +do not use -R or -x abi=generic as those can be needlessly +slow dumping frame sections. Instead, use the correct +abi (if it exists in dwarfdump.conf) or a generic such +as -x abi=generic100 or -x abi=generic500. +To get MIPS/IRIX register names names and call the old version 2 libdwarf +frame interface use the option '-x abi=mips'. +Without '-R' or '-x abi=' dwarfdump ignores +the dwarfdump.conf file and uses compiled-in generic set of +register names. +If no '-x name=' is given, dwarfdump +looks for "./dwarfdump.conf", "$HOME/.dwarfdump.conf", "/lib/dwarfdump.conf" and takes the first it finds. +If one or more '-x name=' is given the last of these is +used and all other such files are ignored. +.PP +Some -k (checking) options print so-called harmless errors. +These are compiler errors that do not cause any +known problem and are only detected inside libdwarf itself. +These are difficult to properly report in dwarfdump and +any error strings may not appear close to the time the +error was encountered. +.SH URI STYLE INPUT STRINGS +.PP +The and the options taking name strings look for URIs and +translate the URI strings to characters by default +(see -x, -c, -S, -u). +So any single % character is treated as if the following two +characters are hex digits representing the underlying true character. +Various characters are meaningful to shells (such as bash or sh) +and to getopt (such as the space character) +If the URI translation does anything it prints the before and after +of the URI translation on standard output, so inspection of the first +lines of output will show if URI did anything. +The actual options themselves are assumed to be non-URI. +So in the option '-cS&T' the -c portion must be non-URI, but the +& character might cause input issues so '-cS%26T' could be used instead. +To actually input a single % character (in a name, for example), +double it to %% on the command line. +.PP +Options -U (turning off URI interpretation) and -q (making finding +URI sequences silent) give finer control of URI interpretation. +PP +As an example, to get a string'a b' make the string 'a%20b' +(here the quote (') is for exposition not part of the string, though +quote is certainly problematic in a name). +Instead of escaping " quotes in the string, type %25, as in + 'a "b' should be typed 'a%20%25b' +Any characters can be typed in URI style, not just characters +which are problematic to the shell or getopt. +We strongly suggest you not type URI-style characters where +such are not needed or use +the % character itself in command line strings unless you must. +.SH PRINTING OPTIONS +.TP +.B \-a +Print each section as independently as possible. Sections that +can safely be printed independently (like .debug_abbrev) +have relevant info printed in the report (sometimes dependent +on -v). + +.TP +.B \-b +Print the .debug_abbrev section.
