GDB 5.0 2000-03-05


(Am I going backwards or what!)

Can I plead with people to try to get anything outstanding resolved this
week so that the branch can be cut before this comming weekend :-)

In the case of the thread stuff, I'm considering checking to see if the
bugs were in GDB-4.18.  If they were then I'm likely to argue that they
should be ignored.

PS:  I'm going to be in Sydney Australia at the Linux Expo (
http://www.linuxexpo.com.au/ ) on Tuesday/Wednesday so if you want to
put a name to a face, check the Red Hat stand.

GDB 5.0 issues

Here are all the issues that have been raised vis-a-vis the 5.0 release
(also see
the gdb and other mailing lists). 

Please route all updates to this page through Andrew Cagney (release
coordinator
for 5.0) so that he hopefully doesn't forget them ... 

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. 



                       Out of control :-)

HPUX (???)

Recent fixes have hopefully fixed the immediate problems. Need it to be
checked. 

Cygwin GDB and INSIGHT (Chris Faylor, any one else)

Plenty of recent fixes have gone through. This needs a re-run. 

m68k-motorola-sys (Philippe De Muyter, Elena Zannoni)

Philippe De Muyter writes: 

With the gdb cvs tree of 2000-02-19, on m68k-motorola-sys, configure
correctly
detect that we have `poll', but gdb incorrectly assumes that `poll' can
be used to
wait for `stdin'. On m68k-motorola-sysv, tty's are not stream-based and
not
`poll'able. Should the configure test be enhanced ? I don't think so if
we need to
run a target program to check that, because it would fail if we
cross-compile gdb,
but if it can be determined by other ways, like the presence of some
constants in
some header files then I would agree. We could also always compile in
the `poll'
version if HAVE_POLL, but switch to the the fall-back method at run time
if poll
fails with POLLNVAL. 

HAVE_POLL is not enough It is thought tht --noasync will get around the
problem. Confirm? Alternativly force that to be the default via (ulgh)
xm-*.h files. 

C++ patches (Daniel Berlin, probably David Taylor?)

It may be possible to merge in some outstanding C++ patches now that Dan
is the
maintainer. Will need to tread carefully thought. 

One commentator suggested though that GDB's 4.18 support was
sufficiently
poor for it to be difficult to put a foot wrong :-( :-) 

lin-thread cannot handle thread exit (Mark Kettenis, Michael
Snyder)

The thread_db assisted debugging code doesn't handle exiting threads
properly, at
least in combination with glibc 2.1.3. There are at least two problems
that prevent
this from working: 

Watch point related patches (Eli Zaretskii, Michael Snyder, ???)

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:

GDB manual and (Brian Voumans, Stan Shebs)

Numerous typo's to merge in. 



              Under control (work in progress)

MI tests (Elena Zannoni, Andrew Cagney)

The MI testsuite has suffered bitrot. Elena's investigating it. 

Generic: dlclose() (Jim Kingdon, Jim Blandy)

GDB does not notice when shared libraries are unloaded, in fact it can
get
confused. This is a longstanding bug/limitation but one which is
affecting quite a
few people. We have a patch (see Kingdon's subsequent 21 Feb 2000
message for
testsuite results). 

JimB's is reviewing this patch. 

Generic: Tom's speedups to GDB (Tom Tromey, Jim Blandy)

JimB's approved this patch. It's also been given a post comment (from?)
about an
additional fix that it needs. 

GNU/Linux/x86: Tom's patch to get GDB to compile under old
linuxes (Tom Tromey, Jim Blandy, any other Linux people)

Patch: gdb -vs- Debian 2.0 

JimB reviewing? 

GNU/Linux/x86: Mask off FP values (Linux and co.)

The FP control registers contain some really weird numbers since the
reserved
bits aren't masked of. Patch: Linux i387 fix 

GNU/Linux/x86: Signal tramplines aren't recognized.

Fix for Linux/i386 signal trampolines 

I have a feeling that this was fixed. 

Solaris/x86 - which? (Nick Duffek, Peter Schauer, Michael
Snyder?)

Nick D's working through patches from Michael Snyder and Peter S.
