General To Do List
TODO: GDB 5.0
=============
Here are _all_ the issues that have been raised vis-a-vis the 5.0
release. Also check the GDB, and other, mail archives
(http://sourceware.cygnus.com/ml/gdb/).
If, however, you fix something, then feel free to tweek this file
(deleting the problem). Just send a note to gdb-patches so that I see
the change.
The names in paren are those that might know more about the problem.
They don't necessarily indicate the people that will fix the problem.

GDB 5.0: Must have
------------------ ------------------
These are things that have been identifed as must-have for this
release of GDB.

Watch point related patches (Eli Zaretskii, Michael Snyder, ???)
Eli writes: This doesn't include the watchpoint-related patches I sent
beginning with August or September, and mentioned them again three
weeks ago. Here again are the pointers to the relevant messages:

Tom's speedups to GDB (Tom Tromey, Jim Blandy)
I believe that there was a late breaking fix that stopped a coredump.

Solaris/x86 - which? (Nick Duffek, Peter Schauer, Michael Snyder?)
Nick D's working through patches from Michael Snyder and Peter S.

RFA: breakpoint.c: Minor output fixes for hardware watchpoints
http://sourceware.cygnus.com/ml/gdb-patches/2000-q1/msg00558.html
During implementation of hardware watchpoints on Solaris, I noticed the
following inconsistencies in breakpoint.c output between software and
hardware breakpoints.

GDB 5.0: Nice to have
---------------------
These are things that might make it in 5.0 but don't sit in the
critical path. If they miss the 5.0 cut then they definitly should
make the follow-on release.

Generic: lin-thread cannot handle thread exit (Mark Kettenis, Michael Snyder)
http://sourceware.cygnus.com/ml/gdb/2000-q1/msg00525.html
The thread_db assisted debugging code doesn't handle exiting threads
properly, at least in combination with glibc 2.1.3 (the framework is
there, just not the actual code). There are at least two problems
that prevent this from working.
As an additional reference point, the pre thread_db code didn't work
either.

Java (Anthony Green, David Taylor)
Anthony Green has started contributing late breaking Java patches:
Patch: java tests
http://sourceware.cygnus.com/ml/gdb-patches/2000-q1/msg00512.html
Patch: java booleans
http://sourceware.cygnus.com/ml/gdb-patches/2000-q1/msg00515.html
Patch: handle N_MAIN stab
http://sourceware.cygnus.com/ml/gdb-patches/2000-q1/msg00527.html
It should be able to squeeze these in.
--
Pascal (Pierre Muller, David Taylor)
The pascal support patches nave been added to the patch data base. I
[cagney] strongly suspect that they are better suited for 5.1.

Programs run under GDB have SIGCHLD masked.
[I think this can be worked around by using the action command -

GNU/Linux/x86 and random thread signals (and Solaris/SPARC but not
Solaris/x86)
Christopher Blizzard writes:
So, I've done some more digging into this and it looks like Jim
Kingdon has reported this problem in the past:
http://sourceware.cygnus.com/ml/bug-gdb/1999-10/msg00058.html
I can reproduce this problem both with and without Tom's patch. Has
anyone seen this before? Maybe have a solution for it hanging around?
:)
There's a test case for this documented at:
when debugging threaded applications you get extra SIGTRAPs

[There should be a GDB testcase - cagney]

IRIX?
Benjamin Gamsa wrote:
Has anyone successfully built the latest (from cvs) gdb on IRIX6.4 or
later? The first problem I hit is that proc-api.c includes
sys/user.h, which no longer exists under IRIX6.4. If I comment out
that include, the next problem I hit is that PIOCGETPR and PIOCGETU
are no longer defined in IRIX6.4 (presumably related to the
disappearance of user.h).

Regressions (prologue) with devel GCC.
The current head of the GCC branch doesn't co-operate well with GDB
over debug information.

RFA: infrun.c, breakpoint.c: Kludge for Solaris x86 hardware watchpoint support
http://sourceware.cygnus.com/ml/gdb-patches/2000-q1/msg00664.html
Unfortunately I'd need the following kludge to work around a Solaris
x86 kernel problem with hardware watchpoint support. See the comment
in the patches for a description of the problem.

RFD: infrun.c: No bpstat_stop_status call after proceed over break ?
http://sourceware.cygnus.com/ml/gdb-patches/2000-q1/msg00665.html
I am currently trying to fix a GDB bug with missing watchpoint triggers
after proceeding over a breakpoint on x86 targets.

GDB 5.0: Won't have
-------------------
The following are on hold until GDB 5.0 is branched. In general they
won't go in as they unsettle the GDB sources.
--
ATTRIBUTE_UNUSED
The need for this as almost been eliminated. The next version of GCC
(assuming cagney gets the revised patch approved) will be able to
supress unused parameter warnings.
--
Delete macro TARGET_BYTE_ORDER_SELECTABLE.
Patches in the database.

Updated readline
Readline 4.? is out. A merge wouldn't hurt.

Purge PARAMS
Something to do post 5.0 branch

GDB 5.0: Test results
---------------------
Please include:
o the output of `config.guess`
o the date
o the compiler
o a note mentioning the reason
for any serious failures.
--
alpha-dec-osf4.0a, vendor compiler, 2000-03-04
Still has many compile warnings (mostly relating back to PTR vs void*)
but it did compile using:
CC=cc .../configure
make
Test results are:
# of expected passes 6223
# of unexpected failures 103
# of unexpected successes 2
# of expected failures 196
# of unresolved testcases 6
# of unsupported tests 1
Looking at the output it would appear that GDB is stepping into some
functions instead of ``next'' ing over them:
35 dummy();
(gdb) next
dummy () at /home/cagney/GDB-DEJAGNU/src/gdb/testsuite/gdb.base/all-types.c:41
41 {
Since there is no active maintainer, I'd consider this sufficient for
5.0 :-/

http://sourceware.cygnus.com/ml/gdb-testers/2000-q1/msg00030.html
There is a SIGTRAP problem that occures in ptrace.exp (Cagney to
expand on).

Kevins merged it all in.

Builds ok. Problems with some of the thread code. Unfortunate but
not a show stopper. Nick D's still looking at it.
