Contributing to GDB
|
||||
|
||||
GDB is a collaborative project and one which wants to encourage new
|
||||
development. You may wish to fix GDB bugs, improve testing, port GDB
|
||||
to a new platform, update documentation, add new GDB features, and the
|
||||
like. To help with this, there is a lot of documentation
|
||||
available.. In addition to the user guide and internals manual
|
||||
included in the GDB distribution, the GDB web pages also contain much
|
||||
information.
|
||||
|
||||
You may also want to submit your change so that can be considered for
|
||||
conclusion in a future version of GDB (see below). Regardless, we
|
||||
encourage you to distribute the change yourself.
|
||||
|
||||
If you don't feel up to hacking GDB, there are still plenty of ways to
|
||||
help! You can answer questions on the mailing lists, write
|
||||
documentation, find bugs, create a GDB related website (contribute to
|
||||
the official GDB web site), or create a GDB related software
|
||||
package. We welcome all of the above and feel free to ask on the GDB
|
||||
mailing lists if you are looking for feedback or for people to review
|
||||
a work in progress.
|
||||
|
||||
Ref: http://www.gnu.org/software/gdb/
|
||||
|
||||
Finally, there are certain legal requirements and style issues which
|
||||
all contributors need to be aware of.
|
||||
|
||||
o Coding Standards
|
||||
|
||||
All contributions must conform to the GNU Coding Standard.
|
||||
Submissions which do not conform to the standards will be
|
||||
returned with a request to reformat the changes.
|
||||
|
||||
GDB has certain additional coding requirements. Those
|
||||
requirements are explained in the GDB internals documentation
|
||||
in the gdb/doc directory.
|
||||
|
||||
Ref: http://www.gnu.org/prep/standards_toc.html
|
||||
|
||||
|
||||
o Copyright Assignment
|
||||
|
||||
Before we can accept code contributions from you, we need a
|
||||
copyright assignment form filled out and filed with the FSF.
|
||||
|
||||
See some documentation by the FSF for details and contact us
|
||||
(either via the GDB mailing list or the GDB maintainer that is
|
||||
taking care of your contributions) to obtain the relevant
|
||||
forms.
|
||||
|
||||
Small changes can be accepted without a copyright assignment form on file.
|
||||
|
||||
Ref: http://www.gnu.org/prep/maintain.html#SEC6
|
||||
|
||||
|
||||
o Submitting Patches
|
||||
|
||||
Every patch must have several pieces of information before we
|
||||
can properly evaluate it.
|
||||
|
||||
A description of the bug and how your patch fixes this
|
||||
bug. A reference to a testsuite failure is very helpful. For
|
||||
new features a description of the feature and your
|
||||
implementation.
|
||||
|
||||
A ChangeLog entry as plaintext (separate from the patch); see
|
||||
the various ChangeLog files for format and content. Note that,
|
||||
unlike some other projects, we do require ChangeLogs also for
|
||||
documentation (i.e., .texi files).
|
||||
|
||||
The patch itself. If you are accessing the CVS repository use
|
||||
"cvs update; cvs diff -cp"; else, use "diff -cp OLD NEW" or
|
||||
"diff -up OLD NEW". If your version of diff does not support
|
||||
these options, then get the latest version of GNU diff.
|
||||
|
||||
We accept patches as plain text (preferred for the compilers
|
||||
themselves), MIME attachments (preferred for the web pages),
|
||||
or as uuencoded gzipped text.
|
||||
|
||||
When you have all these pieces, bundle them up in a mail
|
||||
message and send it to gdb-patches@sourceware.org. All
|
||||
patches and related discussion should be sent to the
|
||||
gdb-patches mailinglist. For further information on the GDB
|
||||
CVS repository, see the Anonymous read-only CVS access and
|
||||
Read-write CVS access page.
|
||||
|
||||

|
||||
|
||||
Supplemental information for GDB:
|
||||
|
||||
o Please try to run the relevant testsuite before and after
|
||||
committing a patch
|
||||
|
||||
If the contributor doesn't do it then the maintainer will. A
|
||||
contributor might include before/after test results in their
|
||||
contribution.
|
||||
|
||||
|
||||
o For bug fixes, please try to include a way of
|
||||
demonstrating that the patch actually fixes something.
|
||||
|
||||
The best way of doing this is to ensure that the
|
||||
testsuite contains one or more test cases that
|
||||
fail without the fix but pass with the fix.
|
||||
|
||||
People are encouraged to submit patches that extend
|
||||
the testsuite.
|
||||
|
||||
|
||||
o Please read your patch before submitting it.
|
||||
|
||||
A patch containing several unrelated changes or
|
||||
arbitrary reformats will be returned with a request
|
||||
to re-formatting / split it.
|
||||
|
||||
|
||||
o If ``gdb/configure.in'' is modified then you don't
|
||||
need to include patches to the regenerated file
|
||||
``configure''.
|
||||
|
||||
The maintainer will re-generate those files
|
||||
using autoconf (2.13 as of 2000-02-29).
|
||||
|
||||
|
||||
o If ``gdb/gdbarch.sh'' is modified, you don't
|
||||
need to include patches to the generated files
|
||||
``gdbarch.h'' and ``gdbarch.c''.
|
||||
|
||||
See ``gdb/configure.in'' above.
|
||||
|
||||
|
||||
o When submitting a patch that fixes a bug
|
||||
in GDB's bug database a brief reference
|
||||
to the bug can be included in the ChangeLog
|
||||
vis
|
||||
|
||||
* CONTRIBUTE: Mention PR convention.
|
||||
Fix PR gdb/4705.
|
||||
|
||||
The text ``PR gdb/4705'' should also be included
|
||||
in the CVS commit message. That causes the
|
||||
patch to automatically be archived with the PR.

GNU GENERAL PUBLIC LICENSE
|
||||
Version 2, June 1991
|
||||
|
||||
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
|
||||
51 Franklin Street, Fifth Floor,
|
||||
Boston, MA 02110-1301, 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

PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED

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.>
|
||||

|
||||
but WITHOUT ANY WARRANTY; without even the implied warranty of

|
||||
|
||||
You should have received a copy of the GNU General Public License
|
||||
along with this program; if not, write to the Free Software
|
||||

|
||||

|
||||
|
||||
|
||||
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:
|
||||
|
||||

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

GDB Maintainers
|
||||
===============
|
||||
|
||||
|
||||
Overview
|
||||
--------
|
||||
|
||||
This file describes different groups of people who are, together, the
|
||||
maintainers and developers of the GDB project. Don't worry - it sounds
|
||||
more complicated than it really is.
|
||||
|
||||
There are four groups of GDB developers, covering the patch development and
|
||||
review process:
|
||||
|
||||
- The Global Maintainers.
|
||||
|
||||
These are the developers in charge of most daily development. They
|
||||
have wide authority to apply and reject patches, but defer to the
|
||||
Responsible Maintainers (see below) within their spheres of
|
||||
responsibility.
|
||||
|
||||
- The Responsible Maintainers.
|
||||
|
||||
These are developers who have expertise and interest in a particular
|
||||
area of GDB, who are generally available to review patches, and who
|
||||
prefer to enforce a single vision within their areas.
|
||||
|
||||
- The Authorized Committers.
|
||||
|
||||
These are developers who are trusted to make changes within a specific
|
||||
area of GDB without additional oversight.
|
||||
|
||||
- The Write After Approval Maintainers.
|
||||
|
||||
These are developers who have write access to the GDB source tree. They
|
||||
can check in their own changes once a developer with the appropriate
|
||||
authority has approved the changes; they can also apply the Obvious
|
||||
Fix Rule (below).
|
||||
|
||||
All maintainers are encouraged to post major patches to the gdb-patches
|
||||
mailing list for comments, even if they have the authority to commit the
|
||||
patch without review from another maintainer. This especially includes
|
||||
patches which change internal interfaces (e.g. global functions, data
|
||||
structures) or external interfaces (e.g. user, remote, MI, et cetera).
|
||||
|
||||
The term "review" is used in this file to describe several kinds of feedback
|
||||
from a maintainer: approval, rejection, and requests for changes or
|
||||
clarification with the intention of approving a revised version. Review is
|
||||
a privilege and/or responsibility of various positions among the GDB
|
||||
Maintainers. Of course, anyone - whether they hold a position but not the
|
||||
relevant one for a particular patch, or are just following along on the
|
||||
mailing lists for fun, or anything in between - may suggest changes or
|
||||
ask questions about a patch!
|
||||
|
||||
There's also a couple of other people who play special roles in the GDB
|
||||
community, separately from the patch process:
|
||||
|
||||
- The GDB Steering Committee.
|
||||
|
||||
These are the official (FSF-appointed) maintainers of GDB. They have
|
||||
final and overriding authority for all GDB-related decisions, including
|
||||
anything described in this file. The committee is not generally
|
||||
involved in day-to-day development (although its members may be, as
|
||||
individuals).
|
||||
|
||||
- The Release Manager.
|
||||
|
||||
This developer is in charge of making new releases of GDB.
|
||||
|
||||
- The Patch Champions.
|
||||
|
||||
These volunteers make sure that no contribution is overlooked or
|
||||
forgotten.
|
||||
|
||||
Most changes to the list of maintainers in this file are handled by
|
||||
consensus among the global maintainers and any other involved parties.
|
||||
In cases where consensus can not be reached, the global maintainers may
|
||||
ask the Steering Committee for a final decision.
|
||||
|
||||
|
||||
The Obvious Fix Rule
|
||||
--------------------
|
||||
|
||||
All maintainers listed in this file, including the Write After Approval
|
||||
developers, are allowed to check in obvious fixes.
|
||||
|
||||
An "obvious fix" means that there is no possibility that anyone will
|
||||
disagree with the change.
|
||||
|
||||
A good mental test is "will the person who hates my work the most be
|
||||
able to find fault with the change" - if so, then it's not obvious and
|
||||
needs to be posted first. :-)
|
||||
|
||||
Something like changing or bypassing an interface is _not_ an obvious
|
||||
fix, since such a change without discussion will result in
|
||||
instantaneous and loud complaints.
|
||||
|
||||
For documentation changes, about the only kind of fix that is obvious
|
||||
is correction of a typo or bad English usage.
|
||||
|
||||
|
||||
GDB Steering Committee
|
||||
----------------------
|
||||
|
||||
The members of the GDB Steering Committee are the FSF-appointed
|
||||
maintainers of the GDB project.
|
||||
|
||||
The Steering Committee has final authority for all GDB-related topics;
|
||||
they may make whatever changes that they deem necessary, or that the FSF
|
||||
requests. However, they are generally not involved in day-to-day
|
||||
development.
|
||||
|
||||
The current members of the steering committee are listed below, in
|
||||
alphabetical order. Their affiliations are provided for reference only -
|
||||
their membership on the Steering Committee is individual and not through
|
||||
their affiliation, and they act on behalf of the GNU project.
|
||||
|
||||
Jim Blandy (Mozilla)
|
||||
Andrew Cagney (Red Hat)
|
||||
Robert Dewar (AdaCore, NYU)
|
||||
Klee Dienes (Apple)
|
||||
Paul Hilfinger (UC Berkeley)
|
||||
Dan Jacobowitz (CodeSourcery)
|
||||
Stan Shebs (CodeSourcery)
|
||||
Richard Stallman (FSF)
|
||||
Ian Lance Taylor (C2)

||||
Todd Whitesel
|
||||
|
||||
|
||||
Global Maintainers
|
||||
------------------
|
||||
|
||||
The global maintainers may review and commit any change to GDB, except in
|
||||
areas with a Responsible Maintainer available. For major changes, or
|
||||
changes to areas with other active developers, global maintainers are
|
||||
strongly encouraged to post their own patches for feedback before
|
||||
committing.
|
||||
|
||||
The global maintainers are responsible for reviewing patches to any area
|
||||
for which no Responsible Maintainer is listed.
|
||||
|
||||
Global maintainers also have the authority to revert patches which should
|
||||
not have been applied, e.g. patches which were not approved, controversial
|
||||
patches committed under the Obvious Fix Rule, patches with important bugs
|
||||
that can't be immediately fixed, or patches which go against an accepted and
|
||||
documented roadmap for GDB development. Any global maintainer may request
|
||||
the reversion of a patch. If no global maintainer, or responsible
|
||||
maintainer in the affected areas, supports the patch (except for the
|
||||
maintainer who originally committed it), then after 48 hours the maintainer
|
||||
who called for the reversion may revert the patch.
|
||||
|
||||
No one may reapply a reverted patch without the agreement of the maintainer
|
||||
who reverted it, or bringing the issue to the GDB Steering Committee for
|
||||
discussion.
|
||||
|
||||
At the moment there are no documented roadmaps for GDB development; in the
|
||||
future, if there are, a reference to the list will be included here.
|
||||
|
||||
The current global maintainers are (in alphabetical order):
|
||||
|
||||
Jim Blandy jimb@mozilla.com
|
||||
Joel Brobecker brobecker@adacore.com

Release Manager
|
||||
---------------
|
||||
|
||||
The current release manager is: Joel Brobecker <brobecker@adacore.com>
|
||||
|
||||
His responsibilities are:
|
||||
|
||||
* organizing, scheduling, and managing releases of GDB.
|
||||
|
||||
* deciding the approval and commit policies for release branches,
|
||||
and can change them as needed.
|
||||
|
||||
|
||||
|
||||
Patch Champions
|
||||
---------------
|
||||
|
||||
These volunteers track all patches submitted to the gdb-patches list. They
|
||||
endeavor to prevent any posted patch from being overlooked; work with
|
||||
contributors to meet GDB's coding style and general requirements, along with
|
||||
FSF copyright assignments; remind (ping) responsible maintainers to review
|
||||
patches; and ensure that contributors are given credit.
|
||||
|
||||
Current patch champions (in alphabetical order):
|
||||
|
||||
Randolph Chung <tausq@debian.org>
|
||||
|
||||
|
||||
|
||||
Responsible Maintainers
|
||||
-----------------------
|
||||
|
||||
These developers have agreed to review patches in specific areas of GDB, in
|
||||
which they have knowledge and experience. These areas are generally broad;
|
||||
the role of a responsible maintainer is to provide coherent and cohesive
|
||||
structure within their area of GDB, to assure that patches from many
|
||||
different contributors all work together for the best results.
|
||||
|
||||
Global maintainers will defer to responsible maintainers within their areas,
|
||||
as long as the responsible maintainer is active. Active means that
|
||||
responsible maintainers agree to review submitted patches in their area
|
||||
promptly; patches and followups should generally be answered within a week.
|
||||
If a responsible maintainer is interested in reviewing a patch but will not
|
||||
have time within a week of posting, the maintainer should send an
|
||||
acknowledgement of the patch to the gdb-patches mailing list, and
|
||||
plan to follow up with a review within a month. These deadlines are for
|
||||
initial responses to a patch - if the maintainer has suggestions
|
||||
or questions, it may take an extended discussion before the patch
|
||||
is ready to commit. There are no written requirements for discussion,
|
||||
but maintainers are asked to be responsive.
|
||||
|
||||
If a responsible maintainer misses these deadlines occasionally (e.g.
|
||||
vacation or unexpected workload), it's not a disaster - any global
|
||||
maintainer may step in to review the patch. But sometimes life intervenes
|
||||
more permanently, and a maintainer may no longer have time for these duties.
|
||||
When this happens, he or she should step down (either into the Authorized
|
||||
Committers section if still interested in the area, or simply removed from
|
||||
the list of Responsible Maintainers if not).
|
||||
|
||||
If a responsible maintainer is unresponsive for an extended period of time
|
||||
without stepping down, please contact the Global Maintainers; they will try
|
||||
to contact the maintainer directly and fix the problem - potentially by
|
||||
removing that maintainer from their listed position.
|
||||
|
||||
If there are several maintainers for a given domain then any one of them
|
||||
may review a submitted patch.
|
||||
|
||||
Target Instruction Set Architectures:
|
||||
|
||||
The *-tdep.c files. ISA (Instruction Set Architecture) and OS-ABI
|
||||
(Operating System / Application Binary Interface) issues including CPU
|
||||
variants.
|
||||
|
||||
The Target/Architecture maintainer works with the host maintainer when
|
||||
resolving build issues. The Target/Architecture maintainer works with
|
||||
the native maintainer when resolving ABI issues.

The Native maintainer is responsible for target specific native
|
||||
support - typically shared libraries and quirks to procfs/ptrace/...
|
||||
The Native maintainer works with the Arch and Core maintainers when
|
||||
resolving more generic problems.
|
||||
|
||||
The host maintainer ensures that gdb can be built as a cross debugger on
|
||||
their platform.

Known problems in GDB 6.5
|

See also: http://www.gnu.org/software/gdb/bugs/
|

|
||||
|
||||
*** Build problems
|
||||
|
||||
build/1411: build fails on hpux 10.20 and hpux 11.00 with CMA threads
|
||||
|
||||
GDB does not build on HP/UX 10.20 or HP/UX 11.00 if the CMA
|
||||
thread package is installed. The compile error is:
|
||||
|
||||
../../gdb/hpux-thread.c:222: variable-size type declared outside of any function
|
||||
|
||||
This happens only if the CMA thread package is installed.
|
||||
|
||||
As a workaround, you can disable support for CMA threads
|
||||
by editing the file gdb/configure. Find the line:
|
||||
|
||||
if test -f /usr/include/dce/cma_config.h ; then
|
||||
|
||||
And replace it with:
|
||||
|
||||
if false ; then
|
||||
|
||||
*** Misc
|
||||
|
||||
gdb/1560: Control-C does not always interrupt GDB.
|
||||
|
||||
When GDB is busy processing a command which takes a long time to
|
||||
complete, hitting Control-C does not have the expected effect.
|
||||
The command execution is not aborted, and the "QUIT" message confirming
|
||||
the abortion is displayed only after the command has been completed.
|
||||
|
||||
*** C++ support
|
||||
|
||||
gdb/931: GDB could be more generous when reading types C++ templates on input
|
||||
|
||||
When the user types a template, GDB frequently requires the type to be
|
||||
typed in a certain way (e.g. "const char*" as opposed to "const char *"
|
||||
or "char const *" or "char const*").
|
||||
|
||||
gdb/1512: no canonical way to output names of C++ types
|
||||
|
||||
We currently don't have any canonical way to output names of C++ types.
|
||||
E.g. "const char *" versus "char const *"; more subtleties arise when
|
||||
dealing with templates.
|
||||
|
||||
gdb/1516: [regression] local classes, gcc 2.95.3, dwarf-2
|
||||
|
||||
With gcc 2.95.3 and the dwarf-2 debugging format, classes which are
|
||||
defined locally to a function include the demangled name of the function
|
||||
as part of their name. For example, if a function "foobar" contains a
|
||||
local class definition "Local", gdb will say that the name of the class
|
||||
type is "foobar__Fi.0:Local".
|
||||
|
||||
This applies only to classes where the class type is defined inside a
|
||||
function, not to variables defined with types that are defined somewhere
|
||||
outside any function (which most types are).
|
||||
|
||||
gdb/1588: names of c++ nested types in casts must be enclosed in quotes
|
||||
|
||||
You must type
|
||||
(gdb) print ('Foo::Bar') x
|
||||
or
|
||||
(gdb) print ('Foo::Bar' *) y
|
||||
instead of
|
||||
(gdb) print (Foo::Bar) x
|
||||
or
|
||||
(gdb) print (Foo::Bar *) y
|
||||
respectively.
|
||||
|
||||
gdb/1091: Constructor breakpoints ignored
|
||||
gdb/1193: g++ 3.3 creates multiple constructors: gdb 5.3 can't set breakpoints
|
||||
|
||||
When gcc 3.x compiles a C++ constructor or C++ destructor, it generates
|
||||
2 or 3 different versions of the object code. These versions have
|
||||
unique mangled names (they have to, in order for linking to work), but
|
||||
they have identical source code names, which leads to a great deal of
|
||||
confusion. Specifically, if you set a breakpoint in a constructor or a
|
||||
destructor, gdb will put a breakpoint in one of the versions, but your
|
||||
program may execute the other version. This makes it impossible to set
|
||||
breakpoints reliably in constructors or destructors.
|
||||
|
||||
gcc 3.x generates these multiple object code functions in order to
|
||||
implement virtual base classes. gcc 2.x generated just one object code
|
||||
function with a hidden parameter, but gcc 3.x conforms to a multi-vendor
|
||||
ABI for C++ which requires multiple object code functions.
|
||||
|
||||
*** Threads
|
||||
|
||||
threads/1650: manythreads.exp
|
||||
|
||||
On GNU/Linux systems that use the old LinuxThreads thread library, a
|
||||
program rapidly creating and deleting threads can confuse GDB leading
|
||||
to an internal error.
|
||||
|
||||
This problem does not occur on newer systems that use the NPTL
|
||||
library, and did not occur with GDB 6.1.
|
||||
|
||||
threads/2137: Native Solaris Thread Debugging broken.
|
||||
|
||||
Use GDB 6.4 if thread debugging is needed on Solaris.

README for gdb-6.3 release
|
||||
Updated 20, November, 2006
|
||||
|
||||
This is GDB, the GNU source-level debugger.
|
||||
|
||||
A summary of new features is in the file `gdb/NEWS'.
|
||||
|
||||
Check the GDB home page at http://www.gnu.org/software/gdb/ for up to
|
||||
date release information, mailing list links and archives, etc.
|
||||
|
||||
The file `gdb/PROBLEMS' contains information on problems identified
|
||||
late in the release cycle. GDB's bug tracking data base at
|
||||
http://www.gnu.org/software/gdb/bugs/ contains a more complete list of
|
||||
bugs.
|
||||
|
||||
|
||||
Unpacking and Installation -- quick overview
|
||||
==========================
|
||||
|
||||
In this release, the GDB debugger sources, the generic GNU include
|
||||
files, the BFD ("binary file description") library, the readline
|
||||
library, and other libraries all have directories of their own
|
||||
underneath the gdb-6.3 directory. The idea is that a variety of GNU
|
||||
tools can share a common copy of these things. Be aware of variation
|
||||
over time--for example don't try to build gdb with a copy of bfd from
|
||||
a release other than the gdb release (such as a binutils release),
|
||||
especially if the releases are more than a few weeks apart.
|
||||
Configuration scripts and makefiles exist to cruise up and down this
|
||||
directory tree and automatically build all the pieces in the right
|
||||
order.
|
||||
|
||||
When you unpack the gdb-6.3.tar.gz file, you'll find a directory
|
||||
called `gdb-6.3', which contains:
|
||||
|
||||
COPYING config-ml.in gettext.m4 ltconfig sim
|
||||
COPYING.LIB config.guess include ltmain.sh src-release

You can build GDB right in the source directory:
|
||||
|
||||
cd gdb-6.3
|
||||
./configure
|
||||
make
|
||||
cp gdb/gdb /usr/local/bin/gdb (or wherever you want)
|
||||
|
||||
However, we recommend that an empty directory be used instead.
|
||||
This way you do not clutter your source tree with binary files
|
||||
and will be able to create different builds with different
|
||||
configuration options.
|
||||
|
||||
You can build GDB in any empty build directory:
|
||||
|
||||
mkdir build
|
||||
cd build
|
||||
<full path to your sources>/gdb-6.3/configure
|
||||
make
|
||||
cp gdb/gdb /usr/local/bin/gdb (or wherever you want)
|
||||
|
||||
(Building GDB with DJGPP tools for MS-DOS/MS-Windows is slightly
|
||||
different; see the file gdb-6.3/gdb/config/djgpp/README for details.)
|
||||
|
||||
This will configure and build all the libraries as well as GDB. If
|
||||
`configure' can't determine your system type, specify one as its
|
||||
argument, e.g., `./configure sun4' or `./configure decstation'.
|
||||
|
||||
Make sure that your 'configure' line ends in 'gdb-6.3/configure':
|
||||
|
||||
/berman/migchain/source/gdb-6.3/configure # RIGHT
|
||||
/berman/migchain/source/gdb-6.3/gdb/configure # WRONG
|
||||
|
||||
The gdb package contains several subdirectories, such as 'gdb',
|
||||
'bfd', and 'readline'. If your 'configure' line ends in
|
||||
'gdb-6.3/gdb/configure', then you are configuring only the gdb
|
||||
subdirectory, not the whole gdb package. This leads to build errors
|
||||
such as:
|
||||
|
||||
make: *** No rule to make target `../bfd/bfd.h', needed by `gdb.o'. Stop.
|
||||
|
||||
If you get other compiler errors during this stage, see the `Reporting
|
||||
Bugs' section below; there are a few known problems.
|
||||
|
||||
GDB requires an ISO C (ANSI C) compiler. If you do not have an ISO
|
||||
C compiler for your system, you may be able to download and install
|
||||
the GNU CC compiler. It is available via anonymous FTP from the
|
||||
directory `ftp://ftp.gnu.org/pub/gnu/gcc'. GDB also requires an ISO
|
||||
C standard library. The GDB remote server, gdbserver, builds with some
|
||||
non-ISO standard libraries - e.g. for Windows CE.
|
||||
|
||||
GDB uses Expat, an XML parsing library, to implement some target-specific
|
||||
features. Expat will be linked in if it is available at build time, or
|
||||
those features will be disabled. The latest version of Expat should be
|
||||
available from `http://expat.sourceforge.net'.
|
||||
|
||||
GDB can be used as a cross-debugger, running on a machine of one
|
||||
type while debugging a program running on a machine of another type.
|
||||
See below.

||||
More Documentation
|
||||
******************
|
||||
|
||||
All the documentation for GDB comes as part of the machine-readable
|
||||
distribution. The documentation is written in Texinfo format, which
|
||||
is a documentation system that uses a single source file to produce
|
||||
both on-line information and a printed manual. You can use one of the
|
||||
Info formatting commands to create the on-line version of the
|
||||
documentation and TeX (or `texi2roff') to typeset the printed version.
|
||||
|
||||
GDB includes an already formatted copy of the on-line Info version
|
||||
of this manual in the `gdb/doc' subdirectory. The main Info file is
|
||||
`gdb-6.3/gdb/doc/gdb.info', and it refers to subordinate files
|
||||
matching `gdb.info*' in the same directory. If necessary, you can
|
||||
print out these files, or read them with any editor; but they are
|
||||
easier to read using the `info' subsystem in GNU Emacs or the
|
||||
standalone `info' program, available as part of the GNU Texinfo
|
||||
distribution.
|
||||
|
||||
If you want to format these Info files yourself, you need one of the
|
||||
Info formatting programs, such as `texinfo-format-buffer' or
|
||||
`makeinfo'.
|
||||
|
||||
If you have `makeinfo' installed, and are in the top level GDB
|
||||
source directory (`gdb-6.3', in the case of version 6.3), you can make
|
||||
the Info file by typing:
|
||||
|
||||
cd gdb/doc
|
||||
make info
|
||||
|
||||
If you want to typeset and print copies of this manual, you need
|
||||
TeX, a program to print its DVI output files, and `texinfo.tex', the
|
||||
Texinfo definitions file. This file is included in the GDB
|
||||
distribution, in the directory `gdb-6.3/texinfo'.
|
||||
|
||||
TeX is a typesetting program; it does not print files directly, but
|
||||
produces output files called DVI files. To print a typeset document,
|
||||
you need a program to print DVI files. If your system has TeX
|
||||
installed, chances are it has such a program. The precise command to
|
||||
use depends on your system; `lpr -d' is common; another (for PostScript
|
||||
devices) is `dvips'. The DVI print command may require a file name
|
||||
without any extension or a `.dvi' extension.
|
||||
|
||||
TeX also requires a macro definitions file called `texinfo.tex'.
|
||||
This file tells TeX how to typeset a document written in Texinfo
|
||||
format. On its own, TeX cannot read, much less typeset a Texinfo file.
|
||||
`texinfo.tex' is distributed with GDB and is located in the
|
||||
`gdb-6.3/texinfo' directory.
|
||||
|
||||
If you have TeX and a DVI printer program installed, you can typeset
|
||||
and print this manual. First switch to the the `gdb' subdirectory of
|
||||
the main source directory (for example, to `gdb-6.3/gdb') and then type:
|
||||
|
||||
make doc/gdb.dvi
|
||||
|
||||
If you prefer to have the manual in PDF format, type this from the
|
||||
`gdb/doc' subdirectory of the main source directory:
|
||||
|
||||
make gdb.pdf
|
||||
|
||||
For this to work, you will need the PDFTeX package to be installed.
|
||||
|
||||
|
||||
Installing GDB
|
||||
**************
|
||||
|
||||
GDB comes with a `configure' script that automates the process of
|
||||
preparing GDB for installation; you can then use `make' to build the
|
||||
`gdb' program.
|
||||
|
||||
The GDB distribution includes all the source code you need for GDB in
|
||||
a single directory, whose name is usually composed by appending the
|
||||
version number to `gdb'.
|
||||
|
||||
For example, the GDB version 6.3 distribution is in the `gdb-6.3'
|
||||
directory. That directory contains:
|
||||
|
||||
`gdb-6.3/{COPYING,COPYING.LIB}'
|
||||
Standard GNU license files. Please read them.
|
||||
|
||||
`gdb-6.3/bfd'
|
||||
source for the Binary File Descriptor library
|
||||
|
||||
`gdb-6.3/config*'
|
||||
script for configuring GDB, along with other support files
|
||||
|
||||
`gdb-6.3/gdb'
|
||||
the source specific to GDB itself
|
||||
|
||||
`gdb-6.3/include'
|
||||
GNU include files
|
||||
|
||||
`gdb-6.3/libiberty'
|
||||
source for the `-liberty' free software library
|
||||
|
||||
`gdb-6.3/opcodes'
|
||||
source for the library of opcode tables and disassemblers
|
||||
|
||||
`gdb-6.3/readline'
|
||||
source for the GNU command-line interface
|
||||
NOTE: The readline library is compiled for use by GDB, but will
|
||||
not be installed on your system when "make install" is issued.
|
||||
|
||||
`gdb-6.3/sim'
|
||||
source for some simulators (ARM, D10V, SPARC, M32R, MIPS, PPC, V850, etc)
|
||||
|
||||
`gdb-6.3/texinfo'
|
||||
The `texinfo.tex' file, which you need in order to make a printed
|
||||
manual using TeX.
|
||||
|
||||
`gdb-6.3/etc'
|
||||
Coding standards, useful files for editing GDB, and other
|
||||
miscellanea.
|
||||
|
||||
Note: the following instructions are for building GDB on Unix or
|
||||
Unix-like systems. Instructions for building with DJGPP for
|
||||
MS-DOS/MS-Windows are in the file gdb/config/djgpp/README.
|
||||
|
||||
The simplest way to configure and build GDB is to run `configure'
|
||||
from the `gdb-VERSION-NUMBER' source directory, which in this example
|
||||
is the `gdb-6.3' directory.
|
||||
|
||||
First switch to the `gdb-VERSION-NUMBER' source directory if you are
|
||||
not already in it; then run `configure'.
|
||||
|
||||
For example:
|
||||
|
||||
cd gdb-6.3
|
||||
./configure
|
||||
make
|
||||
|
||||
Running `configure' followed by `make' builds the `bfd',
|
||||
`readline', `mmalloc', and `libiberty' libraries, then `gdb' itself.
|
||||
The configured source files, and the binaries, are left in the
|
||||
corresponding source directories.
|
||||
|
||||
`configure' is a Bourne-shell (`/bin/sh') script; if your system
|
||||
does not recognize this automatically when you run a different shell,
|
||||
you may need to run `sh' on it explicitly:
|
||||
|
||||
sh configure
|
||||
|
||||
If you run `configure' from a directory that contains source
|
||||
directories for multiple libraries or programs, such as the `gdb-6.3'
|
||||
source directory for version 6.3, `configure' creates configuration
|
||||
files for every directory level underneath (unless you tell it not to,
|
||||
with the `--norecursion' option).
|
||||
|
||||
You can run the `configure' script from any of the subordinate
|
||||
directories in the GDB distribution, if you only want to configure that
|
||||
subdirectory; but be sure to specify a path to it.
|
||||
|
||||
For example, with version 6.3, type the following to configure only
|
||||
the `bfd' subdirectory:
|
||||
|
||||
cd gdb-6.3/bfd
|
||||
../configure
|
||||
|
||||
You can install `gdb' anywhere; it has no hardwired paths. However,
|
||||
you should make sure that the shell on your path (named by the `SHELL'
|
||||
environment variable) is publicly readable. Remember that GDB uses the
|
||||
shell to start your program--some systems refuse to let GDB debug child
|
||||
processes whose programs are not readable.
|
||||
|
||||
|
||||
Compiling GDB in another directory
|
||||
==================================
|
||||
|
||||
If you want to run GDB versions for several host or target machines,
|
||||
you need a different `gdb' compiled for each combination of host and
|
||||
target. `configure' is designed to make this easy by allowing you to
|
||||
generate each configuration in a separate subdirectory, rather than in
|
||||
the source directory. If your `make' program handles the `VPATH'
|
||||
feature correctly (GNU `make' and SunOS 'make' are two that should),
|
||||
running `make' in each of these directories builds the `gdb' program
|
||||
specified there.
|
||||
|
||||
To build `gdb' in a separate directory, run `configure' with the
|
||||
`--srcdir' option to specify where to find the source. (You also need
|
||||
to specify a path to find `configure' itself from your working
|
||||
directory. If the path to `configure' would be the same as the
|
||||
argument to `--srcdir', you can leave out the `--srcdir' option; it
|
||||
will be assumed.)
|
||||
|
||||
For example, with version 6.3, you can build GDB in a separate
|
||||
directory for a Sun 4 like this:
|
||||
|
||||
cd gdb-6.3
|
||||
mkdir ../gdb-sun4
|
||||
cd ../gdb-sun4
|
||||
../gdb-6.3/configure
|
||||
make
|
||||
|
||||
When `configure' builds a configuration using a remote source
|
||||
directory, it creates a tree for the binaries with the same structure
|
||||
(and using the same names) as the tree under the source directory. In
|
||||
the example, you'd find the Sun 4 library `libiberty.a' in the
|
||||
directory `gdb-sun4/libiberty', and GDB itself in `gdb-sun4/gdb'.
|
||||
|
||||
One popular reason to build several GDB configurations in separate
|
||||
directories is to configure GDB for cross-compiling (where GDB runs on
|
||||
one machine--the host--while debugging programs that run on another
|
||||
machine--the target). You specify a cross-debugging target by giving
|
||||
the `--target=TARGET' option to `configure'.
|
||||
|
||||
When you run `make' to build a program or library, you must run it
|
||||
in a configured directory--whatever directory you were in when you
|
||||
called `configure' (or one of its subdirectories).
|
||||
|
||||
The `Makefile' that `configure' generates in each source directory
|
||||
also runs recursively. If you type `make' in a source directory such
|
||||
as `gdb-6.3' (or in a separate configured directory configured with
|
||||
`--srcdir=PATH/gdb-6.3'), you will build all the required libraries,
|
||||
and then build GDB.
|
||||
|
||||
When you have multiple hosts or targets configured in separate
|
||||
directories, you can run `make' on them in parallel (for example, if
|
||||
they are NFS-mounted on each of the hosts); they will not interfere
|
||||
with each other.
|
||||
|
||||
|
||||
Specifying names for hosts and targets
|
||||
======================================
|
||||
|
||||
The specifications used for hosts and targets in the `configure'
|
||||
script are based on a three-part naming scheme, but some short
|
||||
predefined aliases are also supported. The full naming scheme encodes
|
||||
three pieces of information in the following pattern:
|
||||
|
||||
ARCHITECTURE-VENDOR-OS
|
||||
|
||||
For example, you can use the alias `sun4' as a HOST argument or in a
|
||||
`--target=TARGET' option. The equivalent full name is
|
||||
`sparc-sun-sunos4'.
|
||||
|
||||
The `configure' script accompanying GDB does not provide any query
|
||||
facility to list all supported host and target names or aliases.
|
||||
`configure' calls the Bourne shell script `config.sub' to map
|
||||
abbreviations to full names; you can read the script, if you wish, or
|
||||
you can use it to test your guesses on abbreviations--for example:
|
||||
|
||||
% sh config.sub sun4
|
||||
sparc-sun-sunos4.1.1
|
||||
% sh config.sub sun3
|
||||
m68k-sun-sunos4.1.1
|
||||
% sh config.sub decstation
|
||||
mips-dec-ultrix4.2
|
||||
% sh config.sub hp300bsd
|
||||
m68k-hp-bsd
|
||||
% sh config.sub i386v
|
||||
i386-pc-sysv
|
||||
% sh config.sub i786v
|
||||
Invalid configuration `i786v': machine `i786v' not recognized
|
||||
|
||||
`config.sub' is also distributed in the GDB source directory
|
||||
(`gdb-6.3', for version 6.3).
|
||||
|
||||
|
||||
`configure' options
|
||||
===================
|
||||
|
||||
Here is a summary of the `configure' options and arguments that are
|
||||
most often useful for building GDB. `configure' also has several other
|
||||
options not listed here. *note : (configure.info)What Configure Does,
|
||||
for a full explanation of `configure'.
|
||||
|
||||
configure [--help]
|
||||
[--prefix=DIR]
|
||||
[--srcdir=PATH]
|
||||
[--norecursion] [--rm]
|
||||
[--enable-build-warnings]
|
||||
[--target=TARGET]
|
||||
[--host=HOST]
|
||||
[HOST]
|
||||
|
||||
You may introduce options with a single `-' rather than `--' if you
|
||||
prefer; but you may abbreviate option names if you use `--'.
|
||||
|
||||
`--help'
|
||||
Display a quick summary of how to invoke `configure'.
|
||||
|
||||
`-prefix=DIR'
|
||||
Configure the source to install programs and files under directory
|
||||
`DIR'.
|
||||
|
||||
`--srcdir=PATH'
|
||||
*Warning: using this option requires GNU `make', or another `make'
|
||||
that compatibly implements the `VPATH' feature.*
|
||||
Use this option to make configurations in directories separate
|
||||
from the GDB source directories. Among other things, you can use
|
||||
this to build (or maintain) several configurations simultaneously,
|
||||
in separate directories. `configure' writes configuration
|
||||
specific files in the current directory, but arranges for them to
|
||||
use the source in the directory PATH. `configure' will create
|
||||
directories under the working directory in parallel to the source
|
||||
directories below PATH.
|
||||
|
||||
`--norecursion'
|
||||
Configure only the directory level where `configure' is executed;
|
||||
do not propagate configuration to subdirectories.
|
||||
|
||||
`--rm'
|
||||
Remove the configuration that the other arguments specify.
|
||||
|
||||
`--enable-build-warnings'
|
||||
When building the GDB sources, ask the compiler to warn about any
|
||||
code which looks even vaguely suspicious. You should only using
|
||||
this feature if you're compiling with GNU CC. It passes the
|
||||
following flags:
|
||||
-Wimplicit
|
||||
-Wreturn-type
|
||||
-Wcomment
|
||||
-Wtrigraphs
|
||||
-Wformat
|
||||
-Wparentheses
|
||||
-Wpointer-arith
|
||||
|
||||
`--target=TARGET'
|
||||
Configure GDB for cross-debugging programs running on the specified
|
||||
TARGET. Without this option, GDB is configured to debug programs
|
||||
that run on the same machine (HOST) as GDB itself.
|
||||
|
||||
There is no convenient way to generate a list of all available
|
||||
targets.
|
||||
|
||||
`--host=HOST'
|
||||
Configure GDB to run on the specified HOST.
|
||||
|
||||
There is no convenient way to generate a list of all available
|
||||
hosts.
|
||||
|
||||
`HOST ...'
|
||||
Same as `--host=HOST'. If you omit this, GDB will guess; it's
|
||||
quite accurate.
|
||||
|
||||
`configure' accepts other options, for compatibility with configuring
|
||||
other GNU tools recursively; but these are the only options that affect
|
||||
GDB or its supporting libraries.
|
||||
|
||||
|
||||
Remote debugging
|
||||
=================
|
||||
|
||||
The files m68k-stub.c, i386-stub.c, and sparc-stub.c are examples
|
||||
of remote stubs to be used with remote.c. They are designed to run
|
||||
standalone on an m68k, i386, or SPARC cpu and communicate properly
|
||||
with the remote.c stub over a serial line.
|
||||
|
||||
The directory gdb/gdbserver/ contains `gdbserver', a program that
|
||||
allows remote debugging for Unix applications. gdbserver is only
|
||||
supported for some native configurations, including Sun 3, Sun 4, and
|
||||
Linux.
|
||||
The file gdb/gdbserver/README includes further notes on gdbserver; in
|
||||
particular, it explains how to build gdbserver for cross-debugging
|
||||
(where gdbserver runs on the target machine, which is of a different
|
||||
architecture than the host machine running GDB).
|
||||
|
||||
There are a number of remote interfaces for talking to existing ROM
|
||||
monitors and other hardware:
|
||||
|
||||
remote-mips.c MIPS remote debugging protocol
|
||||
remote-sds.c PowerPC SDS monitor
|
||||
remote-sim.c Generalized simulator protocol
|
||||
|
||||
|
||||
Reporting Bugs in GDB
|
||||
=====================
|
||||
|
||||
There are several ways of reporting bugs in GDB. The prefered
|
||||
method is to use the World Wide Web:
|
||||
|
||||
http://www.gnu.org/software/gdb/bugs/
|
||||
|
||||
As an alternative, the bug report can be submitted, via e-mail, to the
|
||||
address "bug-gdb@gnu.org".
|
||||
|
||||
When submitting a bug, please include the GDB version number (e.g.,
|
||||
gdb-6.3), and how you configured it (e.g., "sun4" or "mach386 host,
|
||||
i586-intel-synopsys target"). Since GDB now supports so many
|
||||
different configurations, it is important that you be precise about
|
||||
this. If at all possible, you should include the actual banner that
|
||||
GDB prints when it starts up, or failing that, the actual configure
|
||||
command that you used when configuring GDB.
|
||||
|
||||
For more information on how/whether to report bugs, see the
|
||||
Reporting Bugs chapter of the GDB manual (gdb/doc/gdb.texinfo).
|
||||
|
||||
|
||||
Graphical interface to GDB -- X Windows, MS Windows
|
||||
==========================
|
||||
|
||||
Several graphical interfaces to GDB are available. You should
|
||||
check:
|
||||
|
||||
http://www.gnu.org/software/gdb/links/
|
||||
|
||||
for an up-to-date list.
|
||||
|
||||
Emacs users will very likely enjoy the Grand Unified Debugger mode;
|
||||
try typing `M-x gdb RET'.
|
||||
|
||||
|
||||
Writing Code for GDB
|
||||
=====================
|
||||
|
||||
There is a lot of information about writing code for GDB in the
|
||||
internals manual, distributed with GDB in gdb/doc/gdbint.texinfo. You
|
||||
can read it by hand, print it by using TeX and texinfo, or process it
|
||||
into an `info' file for use with Emacs' info mode or the standalone
|
||||
`info' program.
|
||||
|
||||
If you are pondering writing anything but a short patch, especially
|
||||
take note of the information about copyrights in the node Submitting
|
||||
Patches. It can take quite a while to get all the paperwork done, so
|
||||
we encourage you to start that process as soon as you decide you are
|
||||
planning to work on something, or at least well ahead of when you
|
||||
think you will be ready to submit the patches.

GDB Testsuite
|
||||
=============
|
||||
|
||||
Included with the GDB distribution is a DejaGNU based testsuite
|
||||
that can either be used to test your newly built GDB, or for
|
||||
regression testing a GDB with local modifications.
|
||||
|
||||
Running the testsuite requires the prior installation of DejaGNU,
|
||||
which is generally available via ftp. The directory
|
||||
ftp://sources.redhat.com/pub/dejagnu/ will contain a recent snapshot.
|
||||
Once DejaGNU is installed, you can run the tests in one of the
|
||||
following ways:
|
||||
|
||||
(1) cd gdb-6.3
|
||||
make check-gdb
|
||||
|
||||
or
|
||||
|
||||
(2) cd gdb-6.3/gdb
|
||||
make check
|
||||
|
||||
or
|
||||
|
||||
(3) cd gdb-6.3/gdb/testsuite
|
||||
make site.exp (builds the site specific file)
|
||||
runtest -tool gdb GDB=../gdb (or GDB=<somepath> as appropriate)
|
||||
|
||||
The last method gives you slightly more control in case of problems
|
||||
with building one or more test executables or if you are using the
|
||||
testsuite `standalone', without it being part of the GDB source tree.
|
||||
|
||||
See the DejaGNU documentation for further details.

|

|

# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
|
||||
# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
|
||||
# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
|
||||
#
|
||||
# Of course, Automake must honor this variable whenever it calls a
|
||||
# tool from the auxiliary directory. The problem is that $srcdir (and
|
||||
# therefore $ac_aux_dir as well) can be either absolute or relative,
|
||||
# depending on how configure is run. This is pretty annoying, since
|
||||
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
|
||||
# source directory, any form will work fine, but in subdirectories a
|
||||
# relative path needs to be adjusted first.
|
||||
#
|
||||
# $ac_aux_dir/missing
|
||||
# fails when called from a subdirectory if $ac_aux_dir is relative
|
||||
# $top_srcdir/$ac_aux_dir/missing
|
||||
# fails if $ac_aux_dir is absolute,
|
||||
# fails when called from a subdirectory in a VPATH build with
|
||||
# a relative $ac_aux_dir
|
||||
#
|
||||
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
|
||||
# are both prefixed by $srcdir. In an in-source build this is usually
|
||||
# harmless because $srcdir is `.', but things will broke when you
|
||||
# start a VPATH build or use an absolute $srcdir.
|
||||
#
|
||||
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
|
||||
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
|
||||
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
|
||||
# and then we would define $MISSING as
|
||||
# MISSING="\${SHELL} $am_aux_dir/missing"
|
||||
# This will work as long as MISSING is not called from configure, because
|
||||
# unfortunately $(top_srcdir) has no meaning in configure.
|
||||
# However there are other variables, like CC, which are often used in
|
||||
# configure, and could therefore not use this "fixed" $ac_aux_dir.
|
||||
#
|
||||
# Another solution, used here, is to always expand $ac_aux_dir to an
|
||||
# absolute PATH. The drawback is that using absolute paths prevent a
|
||||
# configured tree to be moved without reconfiguration.

definition, we represent it with an OP_VAR_VALUE, even though

it may turn out to be within a record aggregate. Aggregate
|
||||
evaluation can use either OP_NAMEs or OP_VAR_VALUEs to get a
|

record field name, and can evaluate OP_VAR_VALUE normally to
|

get its value as an expression. Unfortunately, we lose out in

cases where X has multiple meanings and is part of an array

parentheses around X. */

/* An address map is essentially a table mapping CORE_ADDRs onto GDB
|
||||
data structures, like blocks, symtabs, partial symtabs, and so on.
|
||||
An address map uses memory proportional to the number of
|
||||
transitions in the map, where a CORE_ADDR N is mapped to one
|
||||
object, and N+1 is mapped to a different object.
|
||||
|
||||
Address maps come in two flavors: fixed, and mutable. Mutable
|
||||
address maps consume more memory, but can be changed and extended.
|
||||
A fixed address map, once constructed (from a mutable address map),
|
||||
can't be edited. Both kinds of map are allocated in obstacks. */
|
||||
|
||||
/* The opaque type representing address maps. */
|
||||
struct addrmap;
|
||||
|
||||
/* Create a mutable address map which maps every address to NULL.
|
||||

|
||||
/* In the mutable address map MAP, associate the addresses from START
|
||||
to END_INCLUSIVE that are currently associated with NULL with OBJ
|
||||
instead. Addresses mapped to an object other than NULL are left
|
||||
unchanged.
|
||||
|
||||
As the name suggests, END_INCLUSIVE is also mapped to OBJ. This
|
||||
convention is unusual, but it allows callers to accurately specify
|
||||
ranges that abut the top of the address space, and ranges that
|
||||
cover the entire address space.
|
||||
|
||||
This operation seems a bit complicated for a primitive: if it's
|
||||
needed, why not just have a simpler primitive operation that sets a
|
||||
range to a value, wiping out whatever was there before, and then
|
||||
let the caller construct more complicated operations from that,
|
||||
along with some others for traversal?
|
||||
|
||||
It turns out this is the mutation operation we want to use all the
|
||||
time, at least for now. Our immediate use for address maps is to
|
||||
represent lexical blocks whose address ranges are not contiguous.
|
||||
We walk the tree of lexical blocks present in the debug info, and
|
||||
only create 'struct block' objects after we've traversed all a
|
||||
block's children. If a lexical block declares no local variables
|
||||
(and isn't the lexical block for a function's body), we omit it
|
||||
from GDB's data structures entirely.
|
||||
|
||||
However, this menas that we don't decide to create a block (and
|
||||
thus record it in the address map) until after we've traversed its
|
||||
children. If we do decide to create the block, we do so at a time
|
||||
when all its children have already been recorded in the map. So
|
||||
this operation --- change only those addresses left unset --- is
|
||||
actually the operation we want to use every time.
|
||||
|
||||
It seems simpler to let the code which operates on the
|
||||
representation directly deal with the hair of implementing these
|
||||
semantics than to provide an interface which allows it to be
|
||||
implemented efficiently, but doesn't reveal too much of the
|
||||
representation. */

Dynamic Linking on ARM GNU/Linux
|
||||
--------------------------------
|
||||
|
||||
Note: PLT = procedure linkage table
|
||||
GOT = global offset table
|
||||
|
||||
As much as possible, ELF dynamic linking defers the resolution of
|
||||
jump/call addresses until the last minute. The technique used is
|
||||
inspired by the i386 ELF design, and is based on the following
|
||||
constraints.
|
||||
|
||||
1) The calling technique should not force a change in the assembly
|
||||
code produced for apps; it MAY cause changes in the way assembly
|
||||
code is produced for position independent code (i.e. shared
|
||||
libraries).
|
||||
|
||||
2) The technique must be such that all executable areas must not be
|
||||
modified; and any modified areas must not be executed.
|
||||
|
||||
To do this, there are three steps involved in a typical jump:
|
||||
|
||||
1) in the code
|
||||
2) through the PLT
|
||||
3) using a pointer from the GOT
|
||||
|
||||
When the executable or library is first loaded, each GOT entry is
|
||||
initialized to point to the code which implements dynamic name
|
||||
resolution and code finding. This is normally a function in the
|
||||
program interpreter (on ARM GNU/Linux this is usually
|
||||
ld-linux.so.2, but it does not have to be). On the first
|
||||
invocation, the function is located and the GOT entry is replaced
|
||||
with the real function address. Subsequent calls go through steps
|
||||
1, 2 and 3 and end up calling the real code.
|
||||
|
||||
1) In the code:
|
||||
|
||||
b function_call
|
||||
bl function_call
|
||||
|
||||
This is typical ARM code using the 26 bit relative branch or branch
|
||||
and link instructions. The target of the instruction
|
||||
(function_call is usually the address of the function to be called.
|
||||
In position independent code, the target of the instruction is
|
||||
actually an entry in the PLT when calling functions in a shared
|
||||
library. Note that this call is identical to a normal function
|
||||
call, only the target differs.
|
||||
|
||||
2) In the PLT:
|
||||
|
||||
The PLT is a synthetic area, created by the linker. It exists in
|
||||
both executables and libraries. It is an array of stubs, one per
|
||||
imported function call. It looks like this:
|
||||
|
||||
PLT[0]:
|
||||
str lr, [sp, #-4]! @push the return address (lr)
|
||||
ldr lr, [pc, #16] @load from 6 words ahead
|
||||
add lr, pc, lr @form an address for GOT[0]
|
||||
ldr pc, [lr, #8]! @jump to the contents of that addr
|
||||
|
||||
The return address (lr) is pushed on the stack and used for
|
||||
calculations. The load on the second line loads the lr with
|
||||
&GOT[3] - . - 20. The addition on the third leaves:
|
||||
|
||||
lr = (&GOT[3] - . - 20) + (. + 8)
|
||||
lr = (&GOT[3] - 12)
|
||||
lr = &GOT[0]
|
||||
|
||||
On the fourth line, the pc and lr are both updated, so that:
|
||||
|
||||
pc = GOT[2]
|
||||
lr = &GOT[0] + 8
|
||||
= &GOT[2]
|
||||
|
||||
NOTE: PLT[0] borrows an offset .word from PLT[1]. This is a little
|
||||
"tight", but allows us to keep all the PLT entries the same size.
|
||||
|
||||
PLT[n+1]:
|
||||
ldr ip, [pc, #4] @load offset from gotoff
|
||||
add ip, pc, ip @add the offset to the pc
|
||||
ldr pc, [ip] @jump to that address
|
||||
gotoff: .word GOT[n+3] - .
|
||||
|
||||
The load on the first line, gets an offset from the fourth word of
|
||||
the PLT entry. The add on the second line makes ip = &GOT[n+3],
|
||||
which contains either a pointer to PLT[0] (the fixup trampoline) or
|
||||
a pointer to the actual code.
|
||||
|
||||
3) In the GOT:
|
||||
|
||||
The GOT contains helper pointers for both code (PLT) fixups and
|
||||
data fixups. The first 3 entries of the GOT are special. The next
|
||||
M entries (where M is the number of entries in the PLT) belong to
|
||||
the PLT fixups. The next D (all remaining) entries belong to
|
||||
various data fixups. The actual size of the GOT is 3 + M + D.
|
||||
|
||||
The GOT is also a synthetic area, created by the linker. It exists
|
||||
in both executables and libraries. When the GOT is first
|
||||
initialized , all the GOT entries relating to PLT fixups are
|
||||
pointing to code back at PLT[0].
|
||||
|
||||
The special entries in the GOT are:
|
||||
|
||||
GOT[0] = linked list pointer used by the dynamic loader
|
||||
GOT[1] = pointer to the reloc table for this module
|
||||
GOT[2] = pointer to the fixup/resolver code
|
||||
|
||||
The first invocation of function call comes through and uses the
|
||||
fixup/resolver code. On the entry to the fixup/resolver code:
|
||||
|
||||
ip = &GOT[n+3]
|
||||
lr = &GOT[2]
|
||||
stack[0] = return address (lr) of the function call
|
||||
[r0, r1, r2, r3] are still the arguments to the function call
|
||||
|
||||
This is enough information for the fixup/resolver code to work
|
||||
with. Before the fixup/resolver code returns, it actually calls
|
||||
the requested function and repairs &GOT[n+3]. */

/* There are a couple of different possible stack layouts that

we need to support.
|
||||
|
||||
Before version 2.6.18, the kernel used completely independent
|
||||
layouts for non-RT and RT signals. For non-RT signals the stack
|
||||
began directly with a struct sigcontext. For RT signals the stack
|
||||
began with two redundant pointers (to the siginfo and ucontext),
|
||||
and then the siginfo and ucontext.
|
||||
|
||||
As of version 2.6.18, the non-RT signal frame layout starts with
|
||||
a ucontext and the RT signal frame starts with a siginfo and then
|
||||
a ucontext. Also, the ucontext now has a designated save area
|
||||
for coprocessor registers.
|
||||
|
||||
For RT signals, it's easy to tell the difference: we look for
|
||||
pinfo, the pointer to the siginfo. If it has the expected
|
||||
value, we have an old layout. If it doesn't, we have the new
|
||||
layout.
|
||||
|
||||
For non-RT signals, it's a bit harder. We need something in one
|
||||
layout or the other with a recognizable offset and value. We can't
|
||||
use the return trampoline, because ARM usually uses SA_RESTORER,
|
||||
in which case the stack return trampoline is not filled in.
|
||||
We can't use the saved stack pointer, because sigaltstack might
|
||||
be in use. So for now we guess the new layout... */

GDB's normal evaluation uses struct value, which contains the

expression's value as well as its address or the register it came

from. The `+' operator uses the value, whereas the unary `&'

operator will use the address portion. The `=' operator will use

the address or register number of its left hand side.

The issues are different when generating agent bytecode. Given a

variable reference expression, we should not necessarily generate

code to fetch its value, because the next operator may be `=' or

||||
unary `&'. Instead, when we recurse on a subexpression, we

indicate whether we want that expression to produce an lvalue or an
|

rvalue. If we requested an lvalue, then the recursive call tells

us whether it generated code to compute an address on the stack, or

whether the lvalue lives in a register.

/* It's sometimes useful to be able to debug programs that you can't
|
||||
really stop for more than a fraction of a second. To this end, the
|
||||
user can specify a tracepoint (like a breakpoint, but you don't
|
||||
stop at it), and specify a bunch of expressions to record the
|
||||
values of when that tracepoint is reached. As the program runs,
|
||||
GDB collects the values. At any point (possibly while values are
|
||||
still being collected), the user can display the collected values.
|
||||
|
||||
This is used with remote debugging; we don't really support it on
|
||||
native configurations.
|
||||
|
||||
This means that expressions are being evaluated by the remote agent,
|
||||
which doesn't have any access to the symbol table information, and
|
||||
needs to be small and simple.
|
||||
|
||||
The agent_expr routines and datatypes are a bytecode language
|
||||
designed to be executed by the agent. Agent expressions work in
|
||||
terms of fixed-width values, operators, memory references, and
|
||||
register references. You can evaluate a agent expression just given
|
||||
a bunch of memory and register values to sniff at; you don't need
|
||||
any symbolic information like variable names, types, etc.
|
||||
|
||||
GDB translates source expressions, whose meaning depends on
|
||||
symbolic information, into agent bytecode expressions, whose meaning
|
||||
is independent of symbolic information. This means the agent can
|
||||
evaluate them on the fly without reference to data only available
|
||||
to the host GDB. */

/* A bcache is a data structure for factoring out duplication in
|
||||
read-only structures. You give the bcache some string of bytes S.
|
||||
If the bcache already contains a copy of S, it hands you back a
|
||||
pointer to its copy. Otherwise, it makes a fresh copy of S, and
|
||||
hands you back a pointer to that. In either case, you can throw
|
||||
away your copy of S, and use the bcache's.
|
||||
|
||||
The "strings" in question are arbitrary strings of bytes --- they
|
||||
can contain zero bytes. You pass in the length explicitly when you
|
||||
call the bcache function.
|
||||
|
||||
This means that you can put ordinary C objects in a bcache.
|
||||
However, if you do this, remember that structs can contain `holes'
|
||||
between members, added for alignment. These bytes usually contain
|
||||
garbage. If you try to bcache two objects which are identical from
|
||||
your code's point of view, but have different garbage values in the
|
||||
structure's holes, then the bcache will treat them as separate
|
||||
strings, and you won't get the nice elimination of duplicates you
|
||||
were hoping for. So, remember to memset your structures full of
|
||||
zeros before bcaching them!
|
||||
|
||||
You shouldn't modify the strings you get from a bcache, because:
|
||||
|
||||
- You don't necessarily know who you're sharing space with. If I
|
||||
stick eight bytes of text in a bcache, and then stick an eight-byte
|
||||
structure in the same bcache, there's no guarantee those two
|
||||
objects don't actually comprise the same sequence of bytes. If
|
||||
they happen to, the bcache will use a single byte string for both
|
||||
of them. Then, modifying the structure will change the string. In
|
||||
bizarre ways.
|
||||
|
||||
- Even if you know for some other reason that all that's okay,
|
||||
there's another problem. A bcache stores all its strings in a hash
|
||||
table. If you modify a string's contents, you will probably change
|
||||
its hash value. This means that the modified string is now in the
|
||||
wrong place in the hash table, and future bcache probes will never
|
||||
find it. So by mutating a string, you give up any chance of
|
||||
sharing its space with future duplicates.
|
||||
|
||||
|
||||
Size of bcache VS hashtab:
|
||||
|
||||
For bcache, the most critical cost is size (or more exactly the
|
||||
overhead added by the bcache). It turns out that the bcache is
|
||||
remarkably efficient.
|
||||
|
||||
Assuming a 32-bit system (the hash table slots are 4 bytes),
|
||||
ignoring alignment, and limit strings to 255 bytes (1 byte length)
|
||||
we get ...
|
||||
|
||||
bcache: This uses a separate linked list to track the hash chain.
|
||||
The numbers show roughly 100% occupancy of the hash table and an
|
||||
average chain length of 4. Spreading the slot cost over the 4
|
||||
chain elements:
|
||||
|
||||
4 (slot) / 4 (chain length) + 1 (length) + 4 (chain) = 6 bytes
|
||||
|
||||
hashtab: This uses a more traditional re-hash algorithm where the
|
||||
chain is maintained within the hash table. The table occupancy is
|
||||
kept below 75% but we'll assume its perfect:
|
||||
|
||||
4 (slot) x 4/3 (occupancy) + 1 (length) = 6 1/3 bytes
|
||||
|
||||
So a perfect hashtab has just slightly larger than an average
|
||||
bcache.
|
||||
|
||||
It turns out that an average hashtab is far worse. Two things
|
||||
hurt:
|
||||
|
||||
- Hashtab's occupancy is more like 50% (it ranges between 38% and
|
||||
75%) giving a per slot cost of 4x2 vs 4x4/3.
|
||||
|
||||
- the string structure needs to be aligned to 8 bytes which for
|
||||
hashtab wastes 7 bytes, while for bcache wastes only 3.
|
||||
|
||||
This gives:
|
||||
|
||||
hashtab: 4 x 2 + 1 + 7 = 16 bytes
|
||||
|
||||
bcache 4 / 4 + 1 + 4 + 3 = 9 bytes
|
||||
|
||||
The numbers of GDB debugging GDB support this. ~40% vs ~70% overhead.
|
||||
|
||||
|
||||
Speed of bcache VS hashtab (the half hash hack):
|
||||
|
||||
While hashtab has a typical chain length of 1, bcache has a chain
|
||||
length of round 4. This means that the bcache will require
|
||||
something like double the number of compares after that initial
|
||||
hash. In both cases the comparison takes the form:
|
||||
|
||||
a.length == b.length && memcmp (a.data, b.data, a.length) == 0
|
||||
|
||||
That is lengths are checked before doing the memcmp.
|
||||
|
||||
For GDB debugging GDB, it turned out that all lengths were 24 bytes
|
||||
(no C++ so only psymbols were cached) and hence, all compares
|
||||
required a call to memcmp. As a hack, two bytes of padding
|
||||
(mentioned above) are used to store the upper 16 bits of the
|
||||
string's hash value and then that is used in the comparison vis:
|
||||
|
||||
a.half_hash == b.half_hash && a.length == b.length && memcmp
|
||||
(a.data, b.data, a.length)
|
||||
|
||||
The numbers from GDB debugging GDB show this to be a remarkable
|
||||
100% effective (only necessary length and memcmp tests being
|
||||
performed).
|
||||
|
||||
Mind you, looking at the wall clock, the same GDB debugging GDB
|
||||
showed only marginal speed up (0.780 vs 0.773s). Seems GDB is too
|
||||
busy doing something else :-(
