Many of them +will be obvious from the code, but over time some +accidental diffences crept in. + + +Code should be indented in multiples of 4 spaces, and +tabs should not be used to indent the source code. +Use the dicheck program to check indenting. + +The struct naming convention is 'struct my_struct_s' for the +struct defined here (meaning the name should end with _s). +It is better to not do struct typedefs of local structs. +Coders should type 'struct mystruct_s'. 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). That makes it much +easier to grep for uses of members. + +Try to keep lines under 80 characters in length. + +Ensure every if() has {} to enclose the actions. + +Use libdwarf.h types for all the data objects you define, +though sometimes an 'unsigned' or 'int' or 'size_t' is +ok in restricted circumstances.

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.

so it is possible to properly print all such. A traditional + DWARF2,3,4,5 consumer can ignore section groups. + To print in more complicate situations the -x groupnumber=3 + (3 as an example) lets you choose a specific group/comdat to print. + Dwarfdump prints out a section-groupnumber table when appropriate + a making it easy to know what groups are present. +March 24, 2017 + dwarfdump: Now argv[0] is checked before setting the program_name + global variable. If it contains '/dwarfdump.O' that part of + the string is shortened to '/dwarfdump'. + Doing this removes a need for the regressiontests to use sed + and shortens the regressiontests runtime on one machine from + 77 minutes to 23 minutes. +September 20, 2016 + dwarfdump now frees all memory it used when it terminates normally. + No malloc space left behind. + It gets a clean report from + valgrind --leak-check=full --show-leak-kinds=all +May 5, 2016 + By default dwarfdump sanitizes strings, so if a corrupted + DWARF file has non-printable bytes in a string they are + each turned into %xx (% followed by + two hex digits for a single string character). + This is safe for terminals to print and shows the actual value. + The '-x nosanitizestrings' option turns off this feature so bytes + are shown as printf and your system show them. + The same format as uri style, but only using % on characters + that may have bad effects if printed to a terminal (not, + for example, space or tab characters). + Nor are normal '%' in a string altered (in uri such would be + turned to %25 or to %%). +February 25, 2015 + Copied dwgetopt.c dwgetopt.h from libdwarf so dwarfdump can + use dwgetopt() and still build without necessarily + having the libdwarfsource easily available. + Some environments do not have a getopt() so copying + dwgetopt.h,.h here ensures we have this functionality + for everyone. +January 08, 2015 + dwarfdump does new checking. See options -kD -kG -ku -kuf. + In addition, dwarfdump output can be written to a file without + using redirection by using the new -O file= + option. +January 29, 2014 + Now using dwarf_tsearch() so tsearch is available on every platform. +November 17, 2012 + Added new checking options. + To get good relocation-handling dwarfdump now expects to read + headers from libdwarf with the relocation numbers. That means + building dwarfdump separate from the libdwarf source is no + longer as useful as it was. It is best to build libdwarf + and dwarfdump together for decent handling of relocatable + objects. +December 13, 2011 + Now prints missing line table column number as 0 (now + matching the DWARF spec), the previous + practice of printing -1 was always wrong. + And prints the DWARF3/4 new line table fields (when present). +October 29, 2011 + Added support for printing .debug_types (type unit) data. +October 26, 2011 + Added new features to Makefile.in and documented in README + how to build dwarfdump with headers or libraries in + non-standard places. +October 23, 2011 + By default the various places with string option values + and file paths all use URI transformation on input and + if the transformation does anything at all dwarfdump reports + the input and transformed strings. This makes it easy + to deal with strings and expressions and file paths + that are difficult to express in a shell (or that getopt + mangles). Options -q and -U give you control over this process. +October 07, 2011 + The -x abi=mips frame register abi in dwarfdump.conf is now + usable with modern MIPS objects as well as old IRIX objects. + There are other mips-* frame register setups described + in dwarfdump.conf for anyone testing that nothing new has + been added that conflicts with old IRIX/MIPS frame generation. +June 04, 2011 + Error checking is now distinct from section printing, making + error checking (the -k options) much easier to work with on + large objects. + So compiler-created errors can be found, the error reporting + now prints context information. +March 29, 2011 + Added many new correctness tests. Changed the format of + various items (line data prints in a more compact form, numbers + are more uniformly hexadecimal fixed length where that makes sense). + All the source files are uniformly indented to a multiple of 4 + characters and all intent-tabs in the source have been removed. + Major logic changes involved changing error-reporting to be + more detailed and adding new tests for incorrect DWARF. + Now reports error summary by the compiler name, not just overall. +January 26, 2010 + Changed the default frame-data register names from MIPS to + a generic set of registers. + Try '-x abi=mips' to get the traditional old MIPS register + naming. +June 22, 2009 + Added the -S option to dwarfdump. +June 10, 2009 + Moved the gennames.c code to libdwarf. +May 4, 2009 + Replaced awk source-generation of certain functions + with new gennames.c code. + Now we can print an object with an address_size that + varies by compilation unit. +April 4, 2009 + Corrected aspects of the frame-printing by ensuring we pass + all the information libdwarf needs for fully consistent behavior. + Three newly defined libdwarf calls calls made to ensure + that better behavior (specifically having dwarfdump consistently + recognize when registers are the cfa, undefined-value or same-value + pseudo registers). Updated dwarfdump.conf to set these same + things consistently. +Mar 22, 2009 + The -f and -F flags no longer also imply -i (it just + did not make sense to tie them (cannot recall why + it might have been tied before). +Mar 20, 2009 + Moved print_* functions from print_sections.c to individual + source files. Hopefully making the code a bit easier + to read. +Feb 16, 2009 + Added the -C option. It is a sort of 'pedantic' option + as it turns on warnings about certain commonly used + non-standard tag->tag and tag->attr relationships. + Added the tag_attr_ext.list tag_tree_ext.list files which + define the 'common use' extensions. +Feb 14, 2009 + Added configure option --enable-nonstandardprintf + which makes it easy to get printf of Dwarf_Unsigned (etc) + types correct even for non-standard compilers. +December 30, 2008 + Now we print the .debug_ranges section (with -N) + and the data for DW_AT_ranges (with -i). +December 8, 2008 + The -M option now causes printing of FORM details. + And -v adds details about abbreviation 'indexes' into + an abbreviation table (.debug_abbrev) + providing more detail for folks debugging or + improving their understanding of DWARF data. +April 9, 2008 + Added -H to limit the number of compilation-units/FDEs + dwarfdump prints in one run. Added -n to eliminate function-name + printing in .debug_frame output (with a large-enough debug_info + section function-name printing is too slow). The function name + printing will be fixed in another release. +December 8, 2007 + Had to add an ugly configure conditional as libelf has + unconditional use of off64_t in recent libelf.h +July 3, 2007 + Now with -v dwarf expression blocks in frame operations + are printed expanded out. +July 2, 2007 + Added a new abi -x abi=general usable for any cpu with + up to 1000 registers. +May 7, 2007 + Sun Microsystems contributes new dwarf.h extensions and a new -G option + to dwarfdump -i (so one can see the 'global' offset to DIEs). + Thanks to Chris Quenelle of Sun. +April 17, 2006 + New -x name= -x abi= and configuration file + enable sensible printing of a wide range of .debug_frame eh_frame + correctly without recompiling dwarfdump or touching libdwarf.h or + dwarf.h. +March 29, 2005 + Now handles DWARF3. 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 equivalent 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.

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 +If '-x nosanitizestrings' is given then unprintable characters +are not translated to '%xx' (two digit hex +preceded by the '%' character) (with +this option bogus characters +in strings could cause terminal windows to behave oddly). +.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. +.PP +If zlib compression was used on the DWARF sections +in the object file being read the +real section names such as .zdebug_info etc will be reported by +dwarfdump. +When dwarfdump says something is at offset 55 +of .zdebug_info (or the like) keep in mind that +the offset applies to the +uncompressed section (in memory), +not the .zdebug_ compressed section +in \f2objectfilename\fP. +.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.

This makes searching for DIE information +(as with grep) much simpler as the entire DIE is on one line. + +.TP +.B \-D +Turns off the display of section offsets and attribute values in printed output. +So the .debug_info output is just TAGs and Attributes. +For pubnames (and the like) it removes offsets from the output. +For locations lists it removes offsets from the output, but that +is useless since the attribute values don't show so neither does +the location data. + +.TP +.B \-e +Turns on truncation of attribute and tag names. For example +DW_TAG_foo becomes foo. Not compatible with +checking, only useful for printing DIEs. + +.TP +.B \-G +When printing, add global offsets to the offsets printed. + +.TP +.B \-H number +When printing or checking .debug_info, this terminates +the search after 'number' compilation units. When printing +frame information this terminates the FDE reporting +after 'number' FDEs and the CIE reporting (which occurs if one adds -v) +after 'number' CIEs. Example '-H 1' + +.TP +.B \-M +When printing, this means one want to have the FORM show for each attribute. +If a -v is also added (or more than one) then details of any form indirection +are also shown. + +.TP +.B \-n +When printing frames, this turns off the search for function names. +In a really large object the search can take more time than +one wants to wait, so this avoids the search. +.TP +.B \-O file= +The will be used as the file name for output instead +of writing to stdout (stdout is the default). +.TP +.B \-Q +Suppresses section data printing (set automatically with a checking option). + +.TP +.B \-R +When printing frames for ABIs with lots of registers, this allows +up to 1200 registers to be named (like R999) without choosing an ABI +with, for example '-x abi=ppc' + +.TP +.B \-v +Increases the detail shown when printing. +In some sections, using more -v options +will increase the detail (one to three are useful) or may +change the report to show, for example, the actual +line-data-commands instead of the resultant line-table. + +.SH SELECTIVE ENTRY PRINTING + +.PP +These -S options stand alone and basic print information about the compilation +unit and DIE where the string(s) appear. +At most one of each of the following is effective (so for example +one can only have one 'match', but one can +have a 'match', an 'any', and a 'regex'). +Any -S causes the .debug_info section to be inspected. +No checking options or printing options should be supplied with -S. + +If v is added to the -S option, the number of occurrences is printed. +(see below for an example). + +.TP +.B \-S match=string +When printing DIEs +for each tag value or attribute name that matches 'string' exactly +print the compilation unit information and its section offset. +Any CU with no match is not printed. +The 'string' is read as a URI string. +.TP +.B \-S any=string +When printing DIEs +for each tag value or attribute name that contains 'string' +somewhere in the tag or attribute (case insensitive) +print the compilation unit information and its section offset. +Any CU with no match is not printed. +The 'string' is read as a URI string. +.TP +.B \-S regex=string +When printing DIEs +for each tag value or attribute name where the 'string' reqular +expression matches print the compilation unit information +and its section offset. +Any CU with no match is not printed. +The 'string' is read as a URI string. + +.PP +The string cannot have spaces or other characters which are +meaningful to getopt(3) and the shell will strip off quotes and +other characters. +So the string is assumed to be in URI style and is translated. +In other words, to match 'a b' make the -S string 'a%20b' +Instead of escaping " quotes in the string, type %25, as in + 'a "b' should be typed 'a%20%25b' +(the ' are for exposition here, not part of the strings). +Any characters can be typed in URI style, not just characters +which are problematic to the shell or getopt. +.PP +The -S any= and -S regex= options are only usable +if the library functions required are found at configure time. +.PP +The -W option is a modifier to the -S option, and +increases the amount of output -W prints. +An example v modifier to the -S option is shown below. +And we show the -W in context with a -S option. + +.TP +.B \-S vmatch=string1 +Prints information about the +DIEs that -S matches and prints the count of occurrences + +.TP +.B \-S match=string1 -W +Prints the parent tree and the children tree for the +DIEs that -S matches. + +.TP +.B \-S match=string2 -Wp +Prints the parent tree for the DIEs that -S matches. + +.TP +.B \-S match=string3 -Wc +Prints the parent tree for the DIEs that -S matches. + +.SH OTHER OPTIONS + +.TP +.B \-# number +This option controls internal debugging output, +higher numbers mean more debug actions.
