[5.1] Revised TODO list

Hello,
I've decided to be ruthless with the 5.1 todo list and have given
several things the shove (they were moved to general fixes). For each
of what I thought was a significant change, I've hopefully already
posted a separate e-mail noting my intent.
Any way, I've attatched the revised todo list and the diffs as
reference.

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.
--
Update GDB's coding standard documentation. Known topics:
o alloca/malloc et.al.
o typedef and structs
o ISO-C
and most likely also:
o include conventions
--
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://sourceware.cygnus.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?

x86 linux GDB and SIGALRM (???)
http://sourceware.cygnus.com/ml/gdb/2000-q1/msg00803.html
This problem has been fixed, but a regression test still needs to be
added to the testsuite:
http://sourceware.cygnus.com/ml/gdb-patches/2000-05/msg00309.html
[The test has been submitted for approval - cagney]

RFD: infrun.c: No bpstat_stop_status call after proceed over break?
http://sourceware.cygnus.com/ml/gdb-patches/2000-q1/msg00665.html
GDB misses watchpoint triggers after proceeding over a breakpoint on
x86 targets.
--
GDB 5.0 doesn't work on Linux/SPARC
There are two parts to this.
o GDB 5.0 doesn't work on GNU/Linux/SPARC32
o GDB 5.0 doesn't work on the new target
GNU/Linux/SPARC64
GDB does build on both these targets.
The first problem is the one that should be fixed.
--
Re: GDB 5.0.1?
http://sources.redhat.com/ml/gdb/2000-07/msg00038.html
Is the Solaris 8 x86 problem fixed? When you configure it, configure
incorrectly determines that I have no curses.h. This causes mucho
compilation errors later on.
Simply editing the config.h to define CURSES_H fixes the problem, and
then the build works fine.
The status for this problem:
Solaris 8 x86 (PIII-560)
gcc 2.95.2
I had the same problem with several of the snapshots shortly before
5.0 became official, and 5.0 has the same problem.
I sent some mail in about it long ago, and never saw a reply.
I haven't had time to figure it out myself, especially since I get all
confused trying to figure out what configure does, I was happy to find
the workaround.

GDB 5.1 - New features
======================
The following new features should be included in 5.1.
--
Enable MI by default. Old code can be deleted after 5.1 is out.
Issues:
o syntax change where a list would
look like:
[ foo=a, foo=b, foo=c ]
instead of
{ foo=a, foo=b, foo=c }
o kill off the idea of a reverse
query.
o review test cases
o enable it
--
Pascal (Pierre Muller, David Taylor)
Pierre Muller has contributed patches for adding Pascal Language
support to GDB.
2 pascal language patches inserted in database

Indent -gnu ?
http://sourceware.cygnus.com/ml/gdb/2000-q1/msg00496.html
[I think this has been merged, need to confirm - cagney]
--
Java (Anthony Green, David Taylor)
Anthony Green has a number of Java patches that did not make it into
the 5.0 release. The first two are in cvs now, but the third needs
some fixing up before it can go in.
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
--
Add CRIS target.
A predicate to this is the multi-arching of SOFTWARE_SINGLE_STEP(). A
patch has been submitted.
--
GDB 5.1 - Cleanups
==================
The following code cleanups will hopefully be applied to GDB 5.1.
--
Resolve the status of all broken targets as identified by the
MAINTAINERS
file.
--
Change documentation to GFDL license.
``It is time to make an effort to start using the GFDL more
thoroughly. Would all GNU maintainers please change the license to
the GFDL, for all manuals and other major documentation files?
The GFDL and some instructions for using it can be found in
http://www.gnu.org/copyleft/''
RMS
--
Fix copyright notices.
Turns out that ``1998-2000'' isn't considered valid :-(

GDB 5.1 Known Problems
======================
--
z8k
The z8k has suffered bit rot and doesn't build. The problem was in
the opcodes directory.
