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

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

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)

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.

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:

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).

RFA: infrun.c, breakpoint.c: Kludge for Solaris x86 hardware watchpoint support

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.

I am currently trying to fix a GDB bug with missing watchpoint triggers

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.

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 :-/
