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.

||||

||||

|
||||
|
||||
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@sources.redhat.com. 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.
|
||||
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
Preamble
|
||||
|
||||
The licenses for most software are designed to take away your
|
||||
freedom to share and change it. By contrast, the GNU General Public
|
||||
License is intended to guarantee your freedom to share and change free
|
||||
software--to make sure the software is free for all its users. This
|
||||
General Public License applies to most of the Free Software
|
||||
Foundation's software and to any other program whose authors commit to
|
||||
using it. (Some other Free Software Foundation software is covered by
|
||||
the GNU Library General Public License instead.) You can apply it to
|
||||
your programs, too.
|
||||
|
||||
When we speak of free software, we are referring to freedom, not
|
||||
price. Our General Public Licenses are designed to make sure that you
|
||||
have the freedom to distribute copies of free software (and charge for
|
||||
this service if you wish), that you receive source code or can get it
|
||||
if you want it, that you can change the software or use pieces of it
|
||||
in new free programs; and that you know you can do these things.
|
||||
|
||||
To protect your rights, we need to make restrictions that forbid
|
||||
anyone to deny you these rights or to ask you to surrender the rights.
|
||||
These restrictions translate to certain responsibilities for you if you
|
||||
distribute copies of the software, or if you modify it.
|
||||
|
||||
For example, if you distribute copies of such a program, whether
|
||||
gratis or for a fee, you must give the recipients all the rights that
|
||||
you have. You must make sure that they, too, receive or can get the
|
||||
source code. And you must show them these terms so they know their
|
||||
rights.
|
||||
|
||||
We protect your rights with two steps: (1) copyright the software, and
|
||||
(2) offer you this license which gives you legal permission to copy,
|
||||
distribute and/or modify the software.
|
||||
|
||||
Also, for each author's protection and ours, we want to make certain
|
||||
that everyone understands that there is no warranty for this free
|
||||
software. If the software is modified by someone else and passed on, we
|
||||
want its recipients to know that what they have is not the original, so
|
||||
that any problems introduced by others will not reflect on the original
|
||||
authors' reputations.
|
||||
|
||||
Finally, any free program is threatened constantly by software
|
||||
patents. We wish to avoid the danger that redistributors of a free
|
||||
program will individually obtain patent licenses, in effect making the
|
||||
program proprietary. To prevent this, we have made it clear that any
|
||||
patent must be licensed for everyone's free use or not licensed at all.
|
||||
|
||||
The precise terms and conditions for copying, distribution and
|
||||
modification follow.
|
||||
|
||||
GNU GENERAL PUBLIC LICENSE
|
||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
||||
|
||||
0. This License applies to any program or other work which contains
|
||||
a notice placed by the copyright holder saying it may be distributed
|
||||
under the terms of this General Public License. The "Program", below,
|
||||
refers to any such program or work, and a "work based on the Program"
|
||||
means either the Program or any derivative work under copyright law:
|
||||
that is to say, a work containing the Program or a portion of it,
|
||||
either verbatim or with modifications and/or translated into another
|
||||
language. (Hereinafter, translation is included without limitation in
|
||||
the term "modification".) Each licensee is addressed as "you".
|
||||
|
||||
Activities other than copying, distribution and modification are not
|
||||
covered by this License; they are outside its scope. The act of
|
||||
running the Program is not restricted, and the output from the Program
|
||||
is covered only if its contents constitute a work based on the
|
||||
Program (independent of having been made by running the Program).
|
||||
Whether that is true depends on what the Program does.
|
||||
|
||||
1. You may copy and distribute verbatim copies of the Program's
|
||||
source code as you receive it, in any medium, provided that you
|
||||
conspicuously and appropriately publish on each copy an appropriate
|
||||
copyright notice and disclaimer of warranty; keep intact all the
|
||||
notices that refer to this License and to the absence of any warranty;
|
||||
and give any other recipients of the Program a copy of this License
|
||||
along with the Program.
|
||||
|
||||
You may charge a fee for the physical act of transferring a copy, and
|
||||
you may at your option offer warranty protection in exchange for a fee.
|
||||
|
||||
2. You may modify your copy or copies of the Program or any portion
|
||||
of it, thus forming a work based on the Program, and copy and
|
||||
distribute such modifications or work under the terms of Section 1
|
||||
above, provided that you also meet all of these conditions:
|
||||
|
||||
a) You must cause the modified files to carry prominent notices
|
||||
stating that you changed the files and the date of any change.
|
||||
|
||||
b) You must cause any work that you distribute or publish, that in
|
||||
whole or in part contains or is derived from the Program or any
|
||||
part thereof, to be licensed as a whole at no charge to all third
|
||||
parties under the terms of this License.
|
||||
|
||||
c) If the modified program normally reads commands interactively
|
||||
when run, you must cause it, when started running for such
|
||||
interactive use in the most ordinary way, to print or display an
|
||||
announcement including an appropriate copyright notice and a
|
||||
notice that there is no warranty (or else, saying that you provide
|
||||
a warranty) and that users may redistribute the program under
|
||||
these conditions, and telling the user how to view a copy of this
|
||||
License. (Exception: if the Program itself is interactive but
|
||||
does not normally print such an announcement, your work based on
|
||||
the Program is not required to print an announcement.)
|
||||
|
||||
These requirements apply to the modified work as a whole. If
|
||||
identifiable sections of that work are not derived from the Program,
|
||||
and can be reasonably considered independent and separate works in
|
||||
themselves, then this License, and its terms, do not apply to those
|
||||
sections when you distribute them as separate works. But when you
|
||||
distribute the same sections as part of a whole which is a work based
|
||||
on the Program, the distribution of the whole must be on the terms of
|
||||
this License, whose permissions for other licensees extend to the
|
||||
entire whole, and thus to each and every part regardless of who wrote it.
|
||||
|
||||
Thus, it is not the intent of this section to claim rights or contest
|
||||
your rights to work written entirely by you; rather, the intent is to
|
||||
exercise the right to control the distribution of derivative or
|
||||
collective works based on the Program.
|
||||
|
||||
In addition, mere aggregation of another work not based on the Program
|
||||
with the Program (or with a work based on the Program) on a volume of
|
||||
a storage or distribution medium does not bring the other work under
|
||||
the scope of this License.
|
||||
|
||||
3. You may copy and distribute the Program (or a work based on it,
|
||||
under Section 2) in object code or executable form under the terms of
|
||||
Sections 1 and 2 above provided that you also do one of the following:
|
||||
|
||||
a) Accompany it with the complete corresponding machine-readable
|
||||
source code, which must be distributed under the terms of Sections
|
||||
1 and 2 above on a medium customarily used for software interchange; or,
|
||||
|
||||
b) Accompany it with a written offer, valid for at least three
|
||||
years, to give any third party, for a charge no more than your
|
||||
cost of physically performing source distribution, a complete
|
||||
machine-readable copy of the corresponding source code, to be
|
||||
distributed under the terms of Sections 1 and 2 above on a medium
|
||||
customarily used for software interchange; or,
|
||||
|
||||
c) Accompany it with the information you received as to the offer
|
||||
to distribute corresponding source code. (This alternative is
|
||||
allowed only for noncommercial distribution and only if you
|
||||
received the program in object code or executable form with such
|
||||
an offer, in accord with Subsection b above.)
|
||||
|
||||
The source code for a work means the preferred form of the work for
|
||||
making modifications to it. For an executable work, complete source
|
||||
code means all the source code for all modules it contains, plus any
|
||||
associated interface definition files, plus the scripts used to
|
||||
control compilation and installation of the executable. However, as a
|
||||
special exception, the source code distributed need not include
|
||||
anything that is normally distributed (in either source or binary
|
||||
form) with the major components (compiler, kernel, and so on) of the
|
||||
operating system on which the executable runs, unless that component
|
||||
itself accompanies the executable.
|
||||
|
||||
If distribution of executable or object code is made by offering
|
||||
access to copy from a designated place, then offering equivalent
|
||||
access to copy the source code from the same place counts as
|
||||
distribution of the source code, even though third parties are not
|
||||
compelled to copy the source along with the object code.
|
||||
|
||||
4. You may not copy, modify, sublicense, or distribute the Program
|
||||
except as expressly provided under this License. Any attempt
|
||||
otherwise to copy, modify, sublicense or distribute the Program is
|
||||
void, and will automatically terminate your rights under this License.
|
||||
However, parties who have received copies, or rights, from you under
|
||||
this License will not have their licenses terminated so long as such
|
||||
parties remain in full compliance.
|
||||
|
||||
5. You are not required to accept this License, since you have not
|
||||
signed it. However, nothing else grants you permission to modify or
|
||||
distribute the Program or its derivative works. These actions are
|
||||
prohibited by law if you do not accept this License. Therefore, by
|
||||
modifying or distributing the Program (or any work based on the
|
||||
Program), you indicate your acceptance of this License to do so, and
|
||||
all its terms and conditions for copying, distributing or modifying
|
||||
the Program or works based on it.
|
||||
|
||||
6. Each time you redistribute the Program (or any work based on the
|
||||
Program), the recipient automatically receives a license from the
|
||||
original licensor to copy, distribute or modify the Program subject to
|
||||
these terms and conditions. You may not impose any further
|
||||
restrictions on the recipients' exercise of the rights granted herein.
|
||||
You are not responsible for enforcing compliance by third parties to
|
||||
this License.
|
||||
|
||||
7. If, as a consequence of a court judgment or allegation of patent
|
||||
infringement or for any other reason (not limited to patent issues),
|
||||
conditions are imposed on you (whether by court order, agreement or
|
||||
otherwise) that contradict the conditions of this License, they do not
|
||||
excuse you from the conditions of this License. If you cannot
|
||||
distribute so as to satisfy simultaneously your obligations under this
|
||||
License and any other pertinent obligations, then as a consequence you
|
||||
may not distribute the Program at all. For example, if a patent
|
||||
license would not permit royalty-free redistribution of the Program by
|
||||
all those who receive copies directly or indirectly through you, then
|
||||
the only way you could satisfy both it and this License would be to
|
||||
refrain entirely from distribution of the Program.
|
||||
|
||||
If any portion of this section is held invalid or unenforceable under
|
||||
any particular circumstance, the balance of the section is intended to
|
||||
apply and the section as a whole is intended to apply in other
|
||||
circumstances.
|
||||
|
||||
It is not the purpose of this section to induce you to infringe any
|
||||
patents or other property right claims or to contest validity of any
|
||||
such claims; this section has the sole purpose of protecting the
|
||||
integrity of the free software distribution system, which is
|
||||
implemented by public license practices. Many people have made
|
||||
generous contributions to the wide range of software distributed
|
||||
through that system in reliance on consistent application of that
|
||||
system; it is up to the author/donor to decide if he or she is willing
|
||||
to distribute software through any other system and a licensee cannot
|
||||
impose that choice.
|
||||
|
||||
This section is intended to make thoroughly clear what is believed to
|
||||
be a consequence of the rest of this License.
|
||||
|
||||
8. If the distribution and/or use of the Program is restricted in
|
||||
certain countries either by patents or by copyrighted interfaces, the
|
||||
original copyright holder who places the Program under this License
|
||||
may add an explicit geographical distribution limitation excluding
|
||||
those countries, so that distribution is permitted only in or among
|
||||
countries not thus excluded. In such case, this License incorporates
|
||||
the limitation as if written in the body of this License.
|
||||
|
||||
9. The Free Software Foundation may publish revised and/or new versions
|
||||
of the General Public License from time to time. Such new versions will
|
||||
be similar in spirit to the present version, but may differ in detail to
|
||||
address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the Program
|
||||
specifies a version number of this License which applies to it and "any
|
||||
later version", you have the option of following the terms and conditions
|
||||
either of that version or of any later version published by the Free
|
||||
Software Foundation. If the Program does not specify a version number of
|
||||
this License, you may choose any version ever published by the Free Software
|
||||
Foundation.
|
||||
|
||||
10. If you wish to incorporate parts of the Program into other free
|
||||
programs whose distribution conditions are different, write to the author
|
||||
to ask for permission. For software which is copyrighted by the Free
|
||||
Software Foundation, write to the Free Software Foundation; we sometimes
|
||||
make exceptions for this. Our decision will be guided by the two goals
|
||||
of preserving the free status of all derivatives of our free software and
|
||||
of promoting the sharing and reuse of software generally.
|
||||
|
||||
NO WARRANTY
|
||||
|
||||
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
|
||||
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
|
||||
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
|
||||
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
|
||||
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
|
||||
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
|
||||
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
|
||||
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
|
||||
REPAIR OR CORRECTION.
|
||||
|
||||
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
|
||||
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
|
||||
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
|
||||
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
|
||||
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
|
||||
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
|
||||
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
|
||||
POSSIBILITY OF SUCH DAMAGES.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
How to Apply These Terms to Your New Programs
|
||||
|
||||
If you develop a new program, and you want it to be of the greatest
|
||||
possible use to the public, the best way to achieve this is to make it
|
||||
free software which everyone can redistribute and change under these terms.
|
||||
|
||||
To do so, attach the following notices to the program. It is safest
|
||||
to attach them to the start of each source file to most effectively
|
||||
convey the exclusion of warranty; and each file should have at least
|
||||
the "copyright" line and a pointer to where the full notice is found.
|
||||
|
||||
<one line to give the program's name and a brief idea of what it does.>
|
||||

Various Maintainers
|
||||
|
||||
Note individuals who maintain parts of the debugger need approval to
|
||||
check in changes outside of the immediate domain that they maintain.
|
||||
|
||||
If there is no maintainer for a given domain then the responsibility
|
||||
falls to the head maintainer.
|
||||
|
||||
If there are several maintainers for a given domain then
|
||||
responsibility falls to the first maintainer. The first maintainer is
|
||||
free to devolve that responsibility among the other maintainers.
|
||||
|
||||
|
||||
The Obvious Fix Rule
|
||||
|
||||
All maintainers listed in this file 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.
|
||||
|
||||
|
||||
Target/Architecture:
|
||||
|
||||
Generic ISA (Instruction Set Architecture) issues, API variants, CPU
|
||||
variants. *-tdep.c. The Target/Architecture maintainer works with the
|
||||
host maintainer when resolving build issues. The Target/Architecture
|
||||
maintainer works with the native maintainer when resolving API issues.

All developers recognized by this file can make arbitrary changes to
|
||||
OBSOLETE targets.
|
||||
|
||||
All maintainers can test and thence approve non-trivial changes to
|
||||
``maintenance only'' targets submitted by recognized developers.
|
||||
|
||||
All recognized developers can make mechanical changes (by virtue of
|
||||
the obvious fix rule) to ``maintenance only'' targets. The change
|
||||
shall be sanity checked by compiling with one of the listed targets.
|
||||
|
||||
The Bourne shell script:
|
||||
|
||||
cat MAINTAINERS | tr -s '[\t]' '[ ]' | sed -n '
|
||||
/^[ ]*[-a-z0-9\.]*[ ]*[(]*--target=.*/ !d

h
|
||||
b loop
|
||||
:end
|
||||
p
|
||||
'
|
||||
|
||||
can be used to generate a list of buildable targets. The list
|
||||
containing values for the configure options --target=,
|
||||
--enable-gdb-build-warnings= and optionally
|
||||
--enable-sim-build-warnings vis:
|
||||
|
||||
arc-elf ,-Werror

...
|

m68hc11-elf ,-Werror ,
|

...
|
||||
hppa1.1-hp-proelf broken
|
||||
...
|
||||
|
||||
While the ``broken'' targets are included in the listing, the are not
|
||||
expected to build.
|
||||
|
||||
|
||||
Host/Native:
|
||||
|
||||
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 (including mmalloc) can be built
|
||||
as a cross debugger on their platform.

README for gdb-5.2 release
|
||||
Updated 17 April, 2002 by Andrew Cagney
|
||||
|
||||
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-5.2 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-5.2.tar.gz file, you'll find a directory
|
||||
called `gdb-5.2', which contains:
|
||||
|
||||
COPYING config.sub intl missing opcodes
|
||||
COPYING.LIB configure libiberty mkinstalldirs readline
|
||||
Makefile.in configure.in libtool.m4 mmalloc sim
|
||||
README djunpack.bat ltcf-c.sh move-if-change symlink-tree
|
||||
bfd etc ltcf-cxx.sh mpw-README texinfo
|
||||
config gdb ltcf-gcj.sh mpw-build.in utils
|
||||
config-ml.in gettext.m4 ltconfig mpw-config.in ylwrap
|
||||
config.guess include ltmain.sh mpw-configure
|
||||
config.if install-sh md5.sum mpw-install
|
||||
|
||||
You can build GDB right in the source directory:
|
||||
|
||||
cd gdb-5.2
|
||||
./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-5.2/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-5.2/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'.
|
||||
|
||||
If you get 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 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-5.2/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-5.2', in the case of version 5.2), 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-5.2/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-5.2/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-5.2/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 5.2 distribution is in the `gdb-5.2'
|
||||
directory. That directory contains:
|
||||
|
||||
`gdb-5.2/{COPYING,COPYING.LIB}'
|
||||
Standard GNU license files. Please read them.
|
||||
|
||||
`gdb-5.2/bfd'
|
||||
source for the Binary File Descriptor library
|
||||
|
||||
`gdb-5.2/config*'
|
||||
script for configuring GDB, along with other support files
|
||||
|
||||
`gdb-5.2/gdb'
|
||||
the source specific to GDB itself
|
||||
|
||||
`gdb-5.2/include'
|
||||
GNU include files
|
||||
|
||||
`gdb-5.2/libiberty'
|
||||
source for the `-liberty' free software library
|
||||
|
||||
`gdb-5.2/mmalloc'
|
||||
source for the GNU memory-mapped malloc package
|
||||
|
||||
`gdb-5.2/opcodes'
|
||||
source for the library of opcode tables and disassemblers
|
||||
|
||||
`gdb-5.2/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-5.2/sim'
|
||||
source for some simulators (ARM, D10V, SPARC, M32R, MIPS, PPC, V850, etc)
|
||||
|
||||
`gdb-5.2/intl'
|
||||
source for the GNU gettext library, for internationalization.
|
||||
This is slightly modified from the standalone gettext
|
||||
distribution you can get from GNU.
|
||||
|
||||
`gdb-5.2/texinfo'
|
||||
The `texinfo.tex' file, which you need in order to make a printed
|
||||
manual using TeX.
|
||||
|
||||
`gdb-5.2/etc'
|
||||
Coding standards, useful files for editing GDB, and other
|
||||
miscellanea.
|
||||
|
||||
`gdb-5.2/utils'
|
||||
A grab bag of random utilities.
|
||||
|
||||
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-5.2' directory.
|
||||
|
||||
First switch to the `gdb-VERSION-NUMBER' source directory if you are
|
||||
not already in it; then run `configure'.
|
||||
|
||||
For example:
|
||||
|
||||
cd gdb-5.2
|
||||
./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-5.2'
|
||||
source directory for version 5.2, `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 5.2, type the following to configure only
|
||||
the `bfd' subdirectory:
|
||||
|
||||
cd gdb-5.2/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 5.2, you can build GDB in a separate
|
||||
directory for a Sun 4 like this:
|
||||
|
||||
cd gdb-5.2
|
||||
mkdir ../gdb-sun4
|
||||
cd ../gdb-sun4
|
||||
../gdb-5.2/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-5.2' (or in a separate configured directory configured with
|
||||
`--srcdir=PATH/gdb-5.2'), 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-5.2', for version 5.2).
|
||||
|
||||
|
||||
`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'.
|
||||
|
||||

|
||||
|
||||
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.
|
||||
|
||||
There are a number of remote interfaces for talking to existing ROM
|
||||
monitors and other hardware:
|
||||
|
||||
remote-adapt.c AMD 29000 "Adapt"
|
||||
remote-array.c Array Tech RAID controller
|
||||
remote-bug.c Motorola BUG monitor
|
||||
remote-e7000.c Hitachi E7000 ICE
|
||||
remote-eb.c AMD 29000 "EBMON"
|
||||
remote-es.c Ericsson 1800 monitor
|
||||
remote-est.c EST emulator
|
||||
remote-hms.c Hitachi Micro Systems H8/300 monitor
|
||||
remote-mips.c MIPS remote debugging protocol
|
||||
remote-mm.c AMD 29000 "minimon"
|
||||
remote-nindy.c Intel 960 "Nindy"
|
||||
remote-nrom.c NetROM ROM emulator
|
||||
remote-os9k.c PC running OS/9000
|
||||
remote-rdi.c ARM with Angel monitor
|
||||
remote-rdp.c ARM with Demon monitor
|
||||
remote-sds.c PowerPC SDS monitor
|
||||
remote-sim.c Generalized simulator protocol
|
||||
remote-st.c Tandem ST-2000 monitor
|
||||
remote-udi.c AMD 29000 using the AMD "Universal Debug Interface"
|
||||
remote-vx.c VxWorks realtime kernel
|
||||
|
||||
Remote-vx.c and the vx-share subdirectory contain a remote
|
||||
interface for the VxWorks realtime kernel, which communicates over TCP
|
||||
using the Sun RPC library. This would be a useful starting point for
|
||||
other remote- via-ethernet back ends.
|
||||
|
||||
Remote-udi.c and the 29k-share subdirectory contain a remote
|
||||
interface for AMD 29000 programs, which uses the AMD "Universal Debug
|
||||
Interface". This allows GDB to talk to software simulators,
|
||||
emulators, and/or bare hardware boards, via network or serial
|
||||
interfaces. Note that GDB only provides an interface that speaks UDI,
|
||||
not a complete solution. You will need something on the other end
|
||||
that also speaks UDI.
|
||||
|
||||
|
||||
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-5.2), 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/gui/
|
||||
|
||||
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-5.2
|
||||
make check-gdb
|
||||
|
||||
or
|
||||
|
||||
(2) cd gdb-5.2/gdb
|
||||
make check
|
||||
|
||||
or
|
||||
|
||||
(3) cd gdb-5.2/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.

GDB 5.1 - Fixes
|
||||
===============
|
||||
|
||||
Below is a list of problems identified during the GDB 5.0 release
|
||||
cycle. People hope to have these problems fixed in 5.1.
|
||||
|
||||
--
|
||||
|
||||
Wow, three bug reports for the same problem in one day! We should
|
||||
probably make fixing this a real priority :-).
|
||||
|
||||
Anyway, thanks for reporting.
|
||||
|
||||
The following patch will fix the problems with setting breakpoints in
|
||||
dynamically loaded objects:
|
||||
|
||||
http://sources.redhat.com/ml/gdb-patches/2000-05/msg00230.html
|
||||
|
||||
This patch isn't checked in yet (ping Michael/JimB), but I hope this
|
||||
will be in the next GDB release.
|
||||
|
||||
There should really be a test in the testsuite for this problem, since
|
||||
it keeps coming up :-(. Any volunteers?

GDB 5.1 - Known Problems
|
||||
========================
|
||||
|
||||
--
|
||||
|
||||
z8k
|
||||
|
||||
The z8k has suffered bit rot and is known to not build. The problem
|
||||
was occuring in the opcodes directory.
|
||||
|
||||
--
|
||||
|
||||
The BFD directory requires bug-fixed AUTOMAKE et.al.
|
||||
|
||||
AUTOMAKE 1.4 incorrectly set the TEXINPUTS environment variable. It
|
||||
contained the full path to texinfo.tex when it should have only
|
||||
contained the directory. The bug has been fixed in the current
|
||||
AUTOMAKE sources. Automake snapshots can be found in:
|
||||
ftp://sources.redhat.com/pub/gdb/infrastructure
|
||||
and ftp://sources.redhat.com/pub/binutils

Solaris 8 x86 CURSES_H problem
|
||||
http://sources.redhat.com/ml/gdb/2000-07/msg00038.html
|
||||
|
||||
The original problem was worked around with:
|
||||
|
||||
2000-06-06 Michael Snyder <msnyder@cygnus.com>
|
||||
|
||||
* configure.in: Enable autoconf to find curses.h on Solaris 2.8.
|
||||
* configure: Regenerate.
|
||||
|
||||
When building both GDB and SID using the same source tree the problem
|
||||
will still occure. sid/component/configure.in mis-configures
|
||||
<curses.h> and leaves wrong information in the config cache.

GDB 5.2 - Cleanups
|
||||
==================
|
||||
|
||||
The following cleanups have been identified as part of GDB 5.2.
|
||||
|
||||
--
|
||||
|
||||
Remove old code that does not use ui_out functions and all the related
|
||||
"ifdef"s. This also allows the elimination of -DUI_OUT from
|
||||
Makefile.in and configure.in.
|
||||
|
||||
--
|
||||
|
||||
Compiler warnings.
|
||||
|
||||
Eliminate warnings for all targets on at least one host for one of the
|
||||
-W flags. Flags up for debate include: -Wswitch -Wcomment -trigraphs
|
||||
-Wtrigraphs -Wunused-function -Wunused-label -Wunused-variable
|
||||
-Wunused-value -Wchar-subscripts -Wtraditional -Wshadow -Wcast-qual
|
||||
-Wcast-align -Wwrite-strings -Wconversion -Wstrict-prototypes
|
||||
-Wmissing-prototypes -Wmissing-declarations -Wredundant-decls
|
||||
-Woverloaded-virtual -Winline
|
||||
|

--
|
||||
|
||||
Deprecate, if not delete, the following:
|
||||
|
||||
register[]
|
||||
register_valid[]
|
||||
REGISTER_BYTE()
|
||||
Replaced by, on the target side
|
||||
supply_register()
|
||||
and on core-gdb side:
|
||||
{read,write}_register_gen()
|
||||
Remote.c will need to use something
|
||||
other than REGISTER_BYTE() and
|
||||
REGISTER_RAW_SIZE() when unpacking
|
||||
[gG] packets.
|
||||
|
||||
STORE_PSEUDO_REGISTER
|
||||
FETCH_PSEUDO_REGISTER
|
||||
Now handed by the methods
|
||||
gdbarch_{read,write}_register()
|
||||
which sits between core GDB and
|
||||
the register cache.
|
||||
|
||||
REGISTER_CONVERTIBLE
|
||||
REGISTER_CONVERT_TO_RAW
|
||||
REGISTER_CONVERT_TO_VIRTUAL
|
||||
I think these three are redundant.
|
||||
gdbarch_register_{read,write} can
|
||||
do any conversion it likes.
|
||||
|
||||
REGISTER_VIRTUAL_SIZE
|
||||
MAX_REGISTER_VIRTUAL_SIZE
|
||||
REGISTER_VIRTUAL_TYPE
|
||||
I think these can be replaced by
|
||||
the pair:
|
||||
FRAME_REGISTER_TYPE(frame, regnum)
|
||||
REGISTER_TYPE(regnum)
|
||||
|
||||
DO_REGISTERS_INFO
|
||||
Replace with
|
||||
FRAME_REGISTER_INFO (frame, ...)
|
||||
|
||||
REGISTER_SIM_REGNO()
|
||||
If nothing else rename this so that
|
||||
how it relates to rawreg and the
|
||||
regnum is clear.
|
||||
|
||||
REGISTER_BYTES
|
||||
The size of the cache can be computed
|
||||
on the fly.
|
||||
|
||||
IS_TRAPPED_INTERNALVAR
|
||||
The pseudo registers should eventually make
|
||||
this redundant.
|
||||
|
||||
--

Restructure gdb directory tree so that it avoids any 8.3 and 14

|
||||
|
||||
Convert GDB build process to AUTOMAKE.
|

||||
See also sub-directory configure below.
|

GDB 5.2 - Known Problems
|
||||
========================
|
||||
|
||||
--
|
||||
|
||||
Code Cleanups: General
|
||||
======================
|
||||
|
||||
The following are more general cleanups and fixes. They are not tied
|
||||
to any specific release.
|
||||
|
||||
|
||||
New Features and Fixes
|
||||
======================
|
||||
|
||||
These are harder than cleanups but easier than work involving
|
||||
fundamental architectural change.
|
||||
|
||||
--
|
||||
|
||||
Language Support
|
||||
================
|
||||
|
||||
New languages come onto the scene all the time.
|
||||
|
||||
--
|
||||
|
||||
Re: Various C++ things
|
||||
|
||||
RTTI for g++ should be using the typeinfo functions rather than the
|
||||
vtables. The typeinfo functions are always at offset 4 from the
|
||||
beginning of the vtable, and are always right. The vtables will have
|
||||
weird names like E::VB sometimes. The typeinfo function will always
|
||||
be "E type_info function", or somesuch.
|
||||
|
||||
value_virtual_fn_field needs to be fixed so there are no failures for
|
||||
virtual functions for C++ using g++.
|
||||
|
||||
Testsuite cases are the major priority right now for C++ support,
|
||||
since i have to make a lot of changes that could potentially break
|
||||
each other.
|
||||

Symbol Support
|
||||
==============
|
||||
|
||||
--
|
||||
|
||||
Investiagate ways of reducing memory.
|
||||
|
||||
--
|
||||

||||
Investigate ways of improving load time.

Testsuite Support

||||
=================
|
||||
|
||||
There are never to many testcases.
|
||||
|
||||
--
|
||||
|
||||
Better thread testsuite.

|
||||
--
|
||||
|

|
||||
Architectural Changes: General
|
||||
==============================
|
||||
|
||||
These are harder than simple cleanups / fixes and, consequently
|
||||
involve more work. Typically an Architectural Change will be broken
|
||||
down into a more digestible set of cleanups and fixes.
|
||||
|
||||
--
|
||||
|
||||
Architectural Change: Multi-arch et al.
|
||||
=======================================
|
||||
|
||||
The long term objective is to remove all assumptions that there is a
|
||||
single target with a single address space with a single instruction
|
||||
set architecture and single application binary interface.
|
||||
|
||||
This is an ongoing effort. The first milestone is to enable
|
||||
``multi-arch'' where by all architectural decisions are made at
|
||||
runtime.
|
||||
|
||||
It should be noted that ``gdbarch'' is really ``gdbabi'' and
|
||||
``gdbisa''. Once things are multi-arched breaking that down correctly
|
||||
will become much easier.
|
||||
|
||||
--
|
||||
|
||||
Architectural Change: MI, LIBGDB and scripting languages
|
||||
========================================================
|
||||
|
||||
See also architectural changes related to the event loop. LIBGDB
|
||||
can't be finished until there is a generic event loop being used by
|
||||
all targets.
|
||||
|
||||
The long term objective is it to be possible to integrate GDB into
|
||||
scripting languages.
|
||||
|
||||
--
|
||||
|
||||
Architectural Change: Async
|
||||
===========================
|
||||
|
||||
While GDB uses an event loop when prompting the user for input. That
|
||||
event loop is not exploited by targets when they allow the target
|
||||
program to continue. Typically targets still block in (target_wait())
|
||||
until the program again halts.
|
||||
|
||||
The closest a target comes to supporting full asynchronous mode are
|
||||
the remote targets ``async'' and ``extended-async''.

/* Under GNU/Linux, signal handler invocations can be identified by the
|
||||
designated code sequence that is used to return from a signal
|
||||
handler. In particular, the return address of a signal handler
|
||||
points to the following sequence (the first instruction is quadword
|
||||
aligned):
|
||||
|
||||
bis $30,$30,$16
|
||||
addq $31,0x67,$0
|
||||
call_pal callsys
|
||||
|
||||
Each instruction has a unique encoding, so we simply attempt to
|
||||
match the instruction the pc is pointing to with any of the above
|
||||
instructions. If there is a hit, we know the offset to the start
|
||||
of the designated sequence and can then check whether we really are
|
||||
executing in a designated sequence. If not, -1 is returned,
|
||||
otherwise the offset from the start of the desingated sequence is
|
||||
returned.
|
||||
|
||||
There is a slight chance of false hits: code could jump into the
|
||||
middle of the designated sequence, in which case there is no
|
||||
guarantee that we are in the middle of a sigreturn syscall. Don't
|
||||
think this will be a problem in praxis, though. */

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]. */

expression), so we just walk that tree and generate agent bytecodes

as we go along.
|
||||
|
||||
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.
|
||||
|
||||

this is all static analysis of the expression, i.e. analysis which

/* 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. */

Some object/debugging file formats (DWARF version 1, COFF, etc) do not

define fundamental types such as "int" or "double". Others (stabs or

DWARF version 2, etc) do define fundamental types. For the formats which

FIXME: Some compilers distinguish explicitly signed integral types
|

(signed short, signed int, signed long) from "regular" integral types
|

(short, int, long) in the debugging information. There is some dis-
|
||||
agreement as to how useful this feature is. In particular, gcc does
|
||||
not support this. Also, only some debugging formats allow the
|
||||
distinction to be passed on to a debugger. For now, we always just
|
||||
use "short", "int", or "long" as the type name, for both the implicit
|
||||
and explicitly signed types. This also makes life easier for the
|
||||
gdb test suite since we don't have to account for the differences
|
||||
in output depending upon what the compiler and debugging format
|
||||
support. We will probably have to re-examine the issue when gdb

starts taking it's fundamental type information directly from the

debugging information supplied by the compiler. fnf@cygnus.com */
