Suggested projects for aspiring or current GDB hackers
|
||||
======================================================
|
||||
|
||||
(You should probably chat with kingdon@ai.mit.edu to make sure that
|
||||
no one else is doing the project you chose).
|
||||
|
||||
Add watchpoints (break if a memory location changes). This would
|
||||
usually have to involve constant single stepping, but occasionally
|
||||
there is operating system support which gdb should be able to cleanly
|
||||
use (e.g. on the 80386, there are 4 debug registers. By ptracing an
|
||||
address into them, you can get a trap on writes or on reads and
|
||||
writes).
|
||||
|
||||
Rewrite proceed, wait_for_inferior, and normal_stop to clean them up.
|
||||
Suggestions:
|
||||
|
||||
1) Make each test in wait_for_inferior a seperate subroutine
|
||||
call.
|
||||
2) Combine wait_for_inferior and normal_stop to clean up
|
||||
communication via global variables.
|
||||
3) See if you can find some way to clean up the global
|
||||
variables that are used; possibly group them by data flow
|
||||
and information content?
|
||||
|
||||
Work out some kind of way to allow running the inferior to be done as
|
||||
a sub-execution of, eg. breakpoint command lists. Currently running
|
||||
the inferior interupts any command list execution. This would require
|
||||
some rewriting of wait_for_inferior & friends, and hence should
|
||||
probably be done in concert with the above.
|
||||
|
||||
Add function arguments to gdb user defined functions.
|
||||
|
||||
Add convenience variables that refer to exec file, symbol file,
|
||||
selected frame source file, selected frame function, selected frame
|
||||
line number, etc.
|
||||
|
||||
Add a "suspend" subcommand of the "continue" command to suspend gdb
|
||||
while continuing execution of the subprocess. Useful when you are
|
||||
debugging servers and you want to dodge out and initiate a connection
|
||||
to a server running under gdb.
|
||||
|
||||
Make "handle" understand symbolic signal names.
|
||||
|
||||
Work out and implement a reasonably general mechanism for multi-threaded
|
||||
processies. There are parts of one implemented in convex-dep.c, if
|
||||
you want an example.
|
||||
|
||||
A standalone version of gdb on the i386 exists. Anyone who wants to
|
||||
do some serious working cleaning it up and making it a general
|
||||
standalone gdb should contact pace@wheaties.ai.mit.edu.
|
||||
|
||||
Add stab information to allow reasonable debugging of inline functions
|
||||
(possibly they should show up on a stack backtrace? With a note
|
||||
indicating that they weren't "real"?).
|
||||
|
||||
Implement support for specifying arbitrary locations of stack frames
|
||||
(in practice, this usually requires specification of both the top and
|
||||
bottom of the stack frame (fp and sp), since you *must* retrieve the
|
||||
pc that was saved in the innermost frame).
|
||||
|
||||
Modify the naked "until" command to step until past the current source
|
||||
line, rather than past the current pc value. This is tricky simply
|
||||
because the low level routines have no way of specifying a multi-line
|
||||
step range, and there is no way of saying "don't print stuff when we
|
||||
stop" from above (otherwise could just call step many times).
|
||||
|
||||
Modify the handling of symbols grouped through BINCL/EINCL stabs to
|
||||
allocate a partial symtab for each BINCL/EINCL grouping. This will
|
||||
seriously decrease the size of inter-psymtab dependencies and hence
|
||||
lessen the amount that needs to be read in when a new source file is
|
||||
accessed.
|
||||
|
||||
Work out some method of saving breakpoints across the reloading of an
|
||||
executable. Probably this should be by saving the commands by which
|
||||
the breakpoints were set and re-executing them (as text locations may
|
||||
change).
|
||||
|
||||
Do an "x/i $pc" after each stepi or nexti.
|
||||
|
||||
Modify all of the disassemblers to use printf_filtered to get correct
|
||||
more filtering.
|
||||
|
||||
Modify gdb to work correctly with Pascal.
|
||||
|
||||
Rewrite macros that handle frame chaining and frameless functions.
|
||||
They should be able to tell the difference between start, main, and a
|
||||
frameless function called from main.
|
||||
|
||||
Work out what information would need to be included in an executable
|
||||
by the compiler to allow gdb to debug functions which do not have a
|
||||
frame pointer. Modify gdb and gcc to do this.
|
||||
|
||||
When `attached' to a program (via either OS support or remote
|
||||
debugging), gdb should arrange to catch signals which the terminal
|
||||
might send, as it is unlikely that the program will be able to notice
|
||||
them. SIGINT and SIGTSTP are obvious examples.
|
||||
|
||||
Enhance the gdb manual with extra examples where needed.
|
||||
|
||||
Arrange for list_command not to use decode_line_1 and thus not require
|
||||
symbols to be read in simply to read a source file.
|
||||
|
||||
Problem in xgdb; the readline library needs the terminal in CBREAK
|
||||
mode for command line editing, but this makes it difficult to dispatch
|
||||
on button presses. Possible solution: use a define to replace getc in
|
||||
readline.c with a routine that does button dispatches. You should
|
||||
probably see XGDB-README before you fiddle with XGDB. Also, someone
|
||||
is implementing a new xgdb; it may not be worth while fiddling with
|
||||
the old one.

This is GDB, the GNU source-level debugger, presently running under un*x.
|
||||
|
||||
Before compiling GDB, you must tell GDB what kind of machine you are
|
||||
running on. To do this, type `config.gdb machine', where machine is
|
||||
something like `vax' or `sun2'. For a list of valid machine types,
|
||||
type `config.gdb'.
|
||||
|
||||
Normally config.gdb edits the makefile as necessary. If you have to
|
||||
edit the makefile on a standard machine listed in config.gdb this
|
||||
should be considered a bug and reported as such.
|
||||
|
||||
Once these files are set up, just `make' will do everything,
|
||||
producing an executable `gdb' in this directory.
|
||||
|
||||
If you want a new (current to this release) version of the manual, you
|
||||
will have to use the gdb.texinfo file provided with this distribution.
|
||||
The gdb.texinfo file requires the texinfo-format-buffer command from
|
||||
emacs 18.55 or later.
|
||||
|
||||
About languages other than C...
|
||||
|
||||
C++ support has been integrated into gdb. GDB should work with
|
||||
FORTRAN programs (if you have problem, please send a bug report), but
|
||||
I am not aware of anyone who is working on getting it to use the
|
||||
syntax of any language other than C or C++. Pascal programs which use
|
||||
sets, subranges, file variables, or nested functions will not
|
||||
currently work.
|
||||
|
||||
About -gg format...
|
||||
|
||||
Currently GDB version 3.x does *not* support GCC's -gg format. This
|
||||
is because it (in theory) has fast enough startup on dbx debugging
|
||||
format object files that -gg format is unnecessary (and hence
|
||||
undesirable, since it wastes space and processing power in gcc). I
|
||||
would like to hear people's opinions on the amount of time currently
|
||||
spent in startup; is it fast enough?
|
||||
|
||||
About remote debugging...
|
||||
|
||||
The two files remote-multi.shar and remote-sa.m68k.shar contain two
|
||||
examples of a remote stub to be used with remote.c. The the -multi
|
||||
file is a general stub that can probably be running on various
|
||||
different flavors of unix to allow debugging over a serial line from
|
||||
one machine to another. The remote-sa.m68k.shar is designed to run
|
||||
standalone on a 68k type cpu and communicate properley with the
|
||||
remote.c stub over a serial line.
|
||||
|
||||
About reporting bugs...
|
||||
|
||||
The correct address for reporting bugs found with gdb is
|
||||
"bug-gdb@prep.ai.mit.edu". Please send all bugs to that address.
|
||||
|
||||
About xgdb...
|
||||
|
||||
xgdb.c was provided to us by the user community; it is not an integral
|
||||
part of the gdb distribution. The problem of providing visual
|
||||
debugging support on top of gdb is peripheral to the GNU project and
|
||||
(at least right now) we can't afford to put time into it. So while we
|
||||
will be happy to incorporate user fixes to xgdb.c, we do not guarantee
|
||||
that it will work and we will not fix bugs reported in it. Someone is
|
||||
working on writing a new XGDB, so improving (e.g. by fixing it so that
|
||||
it will work, if it doesn't currently) the current one is not worth it.
|
||||
|
||||
For those intersted in auto display of source and the availability of
|
||||
an editor while debugging I suggest trying gdb-mode in gnu-emacs.
|
||||
Comments on this mode are welcome.
|
||||
|
||||
About the machine-dependent files...
|
||||
|
||||
m-<machine>.h (param.h is a link to this file).
|
||||
This file contains macro definitions that express information
|
||||
about the machine's registers, stack frame format and instructions.
|
||||
|
||||
<machine>-opcode.h (opcode.h is a link to this file).
|
||||
<machine>-pinsn.c (pinsn.c is a link to this file).
|
||||
These files contain the information necessary to print instructions
|
||||
for your cpu type.
|
||||
|
||||
<machine>-dep.c (dep.c is a link to this file).
|
||||
Those routines which provide a low level interface to ptrace and which
|
||||
tend to be machine-dependent. (The machine-independent routines are in
|
||||
`infrun.c' and `inflow.c')
|
||||
|
||||
About writing code for GDB...
|
||||
|
||||
We appreciate having users contribute code that is of general use, but
|
||||
for it to be included in future GDB releases it must be cleanly
|
||||
written. We do not want to include changes that will needlessly make future
|
||||
maintainance difficult. It is not much harder to do things right, and
|
||||
in the long term it is worth it to the GNU project, and probably to
|
||||
you individually as well.
|
||||
|
||||
Please code according to the GNU coding standards. If you do not have
|
||||
a copy, you can request one by sending mail to gnu@prep.ai.mit.edu.
|
||||
|
||||
Please try to avoid making machine-specific changes to
|
||||
machine-independent files (i.e. all files except "param.h" and
|
||||
"dep.c". "pinsn.c" and "opcode.h" are processor-specific but not
|
||||
operating system-dependent). If this is unavoidable, put a hook in
|
||||
the machine-independent file which calls a (possibly)
|
||||
machine-dependent macro (for example, the IGNORE_SYMBOL macro can be
|
||||
used for any symbols which need to be ignored on a specific machine.
|
||||
Calling IGNORE_SYMBOL in dbxread.c is a lot cleaner than a maze of #if
|
||||
defined's). The machine-independent code should do whatever "most"
|
||||
machines want if the macro is not defined in param.h. Using #if
|
||||
defined can sometimes be OK (e.g. SET_STACK_LIMIT_HUGE) but should be
|
||||
conditionalized on a specific feature of an operating system (set in
|
||||
param.h) rather than something like #if defined(vax) or #if
|
||||
defined(SYSV).
|
||||
|
||||
It is better to replace entire routines which may be system-specific,
|
||||
rather than put in a whole bunch of hooks which are probably not going
|
||||
to be helpful for any purpose other than your changes. For example,
|
||||
if you want to modify dbxread.c to deal with DBX debugging symbols
|
||||
which are in COFF files rather than BSD a.out files, do something
|
||||
along the lines of a macro GET_NEXT_SYMBOL, which could have
|
||||
different definitions for COFF and a.out, rather than trying to put
|
||||
the necessary changes throughout all the code in dbxread.c that
|
||||
currently assumes BSD format.
|
||||
|
||||
Please avoid duplicating code. For example, if something needs to be
|
||||
changed in read_inferior_memory, it is very painful because there is a
|
||||
copy in every dep.c file. The correct way to do this is to put (in
|
||||
this case) the standard ptrace interfaces in a separate file ptrace.c,
|
||||
which is used by all systems which have ptrace. ptrace.c would deal
|
||||
with variations between systems the same way any system-independent
|
||||
file would (hooks, #if defined, etc.).
|
||||
|
||||
About debugging gdb with itself...
|
||||
|
||||
You probably want to do a "make TAGS" after you configure your
|
||||
distribution; this will put the machine dependent routines for your
|
||||
local machine where they will be accessed first by a M-period .
|
||||
|
||||
Also, make sure that you've compiled gdb with your local cc or taken
|
||||
appropriate precautions regarding ansification of include files. See
|
||||
the Makefile for more information.
|
||||
|
||||
The "info" command, when executed without a subcommand in a gdb being
|
||||
debugged by gdb, will pop you back up to the top level gdb. See
|
||||
.gdbinit for more details.
