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.
|
|
|
|

|
|
|
|
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://sources.redhat.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?

GDB 5.1 - New features
|
|
======================
|
|
|
|
The following new features should be included in 5.1.

GDB 5.1 - Cleanups
|

==================
|
|
|

The following code cleanups will hopefully be applied to GDB 5.1.

GDB 5.1 - Known Problems
|
|
========================
|
|
|
|
--
|
|
|
|
z8k
|
|
|
|
The z8k has suffered bit rot and is known to not build. The problem
|
|
was occuring in the opcodes directory.
|
|
|
|
--
|
|
|
|
The BFD directory requires bug-fixed AUTOMAKE et.al.
|
|
|
|
AUTOMAKE 1.4 incorrectly set the TEXINPUTS environment variable. It
|
|
contained the full path to texinfo.tex when it should have only
|
|
contained the directory. The bug has been fixed in the current
|
|
AUTOMAKE sources. Automake snapshots can be found in:
|
|
ftp://sources.redhat.com/pub/gdb/infrastructure
|
|
and ftp://sources.redhat.com/pub/binutils

Solaris 8 x86 CURSES_H problem
|
|
http://sources.redhat.com/ml/gdb/2000-07/msg00038.html
|
|
|
|
The original problem was worked around with:
|
|
|
|
2000-06-06 Michael Snyder <msnyder@cygnus.com>
|
|
|
|
* configure.in: Enable autoconf to find curses.h on Solaris 2.8.
|
|
* configure: Regenerate.
|
|
|
|
When building both GDB and SID using the same source tree the problem
|
|
will still occure. sid/component/configure.in mis-configures
|
|
<curses.h> and leaves wrong information in the config cache.

GDB 5.2 - New features

======================
|
|
|
|
--
|
|
|
|
GCC 3.0 ABI support (but hopefully sooner...).
|

GDB 5.2 - Cleanups
|
|
==================
|
|
|
|
The following cleanups have been identified as part of GDB 5.2.
|
|
|
|
--
|
|
|
|
Remove old code that does not use ui_out functions and all the related
|
|
"ifdef"s. This also allows the elimination of -DUI_OUT from
|
|
Makefile.in and configure.in.
|
|
|
|
--
|
|
|
|
Compiler warnings.
|
|
|
|
Eliminate warnings for all targets on at least one host for one of the
|
|
-W flags. Flags up for debate include: -Wswitch -Wcomment -trigraphs
|
|
-Wtrigraphs -Wunused-function -Wunused-label -Wunused-variable
|
|
-Wunused-value -Wchar-subscripts -Wtraditional -Wshadow -Wcast-qual
|
|
-Wcast-align -Wwrite-strings -Wconversion -Wstrict-prototypes
|
|
-Wmissing-prototypes -Wmissing-declarations -Wredundant-decls
|
|
-Woverloaded-virtual -Winline

Deprecate, if not delete, the following:
|
|
|
|
register[]
|
|
register_valid[]
|
|
REGISTER_BYTE()
|
|
Replaced by, on the target side
|
|
supply_register()
|
|
and on core-gdb side:
|
|
{read,write}_register_gen()
|
|
Remote.c will need to use something
|
|
other than REGISTER_BYTE() and
|
|
REGISTER_RAW_SIZE() when unpacking
|
|
[gG] packets.
|
|
|
|
STORE_PSEUDO_REGISTER
|
|
FETCH_PSEUDO_REGISTER
|
|
Now handed by the methods
|
|
gdbarch_{read,write}_register()
|
|
which sits between core GDB and
|
|
the register cache.
|
|
|
|
REGISTER_CONVERTIBLE
|
|
REGISTER_CONVERT_TO_RAW
|
|
REGISTER_CONVERT_TO_VIRTUAL
|
|
I think these three are redundant.
|
|
gdbarch_register_{read,write} can
|
|
do any conversion it likes.
|
|
|
|
REGISTER_VIRTUAL_SIZE
|
|
MAX_REGISTER_VIRTUAL_SIZE
|
|
REGISTER_VIRTUAL_TYPE
|
|
I think these can be replaced by
|
|
the pair:
|
|
FRAME_REGISTER_TYPE(frame, regnum)
|
|
REGISTER_TYPE(regnum)
|
|
|
|
DO_REGISTERS_INFO
|
|
Replace with
|
|
FRAME_REGISTER_INFO (frame, ...)
|
|
|
|
REGISTER_SIM_REGNO()
|
|
If nothing else rename this so that
|
|
how it relates to rawreg and the
|
|
regnum is clear.
|
|
|
|
REGISTER_BYTES
|
|
The size of the cache can be computed
|
|
on the fly.
|
|
|
|
IS_TRAPPED_INTERNALVAR
|
|
The pseudo registers should eventually make
|
|
this redundant.
|
|
|
|
--
|
|
|
|
Obsolete the targets:
|
|
|
|
arm*-wince-pe
|
|
mips*-*-pe
|
|
sh*-*-pe
|
|
|
|
--
|
|
|
|
Obsolete the protocols:
|
|
|
|
RDB?
|
|
|
|
``As of version 5.3, WindRiver has removed the RDB server (RDB
|
|
protocol support is built into gdb).'' -- Till.
|
|
|
|
--
|
|
|
|
Restructure gdb directory tree so that it avoids any 8.3 and 14
|
|
filename problems.
|
|
|
|
--
|
|
|
|
Convert GDB build process to AUTOMAKE.
|
|
|
|
See also sub-directory configure below.
|
|
|
|
The current convention is (kind of) to use $(<header>_h) in all
|
|
dependency lists. It isn't done in a consistent way.

GDB 5.2 - Known Problems

Code Cleanups: General
|
|
======================
|
|
|
|
The following are more general cleanups and fixes. They are not tied
|
|
to any specific release.
|
|
|
|
|
|
New Features and Fixes
|
|
======================
|
|
|
|
These are harder than cleanups but easier than work involving
|
|
fundamental architectural change.
|
|
|
|
--
|
|
|
|
Language Support
|
|
================
|
|
|
|
New languages come onto the scene all the time.
|
|
|
|
--
|
|
|
|
Re: Various C++ things
|
|
|
|
value_headof/value_from_vtable_info are worthless, and should be
|
|
removed. The one place in printcmd.c that uses it should use the RTTI
|
|
functions.
|
|
|
|
RTTI for g++ should be using the typeinfo functions rather than the
|
|
vtables. The typeinfo functions are always at offset 4 from the
|
|
beginning of the vtable, and are always right. The vtables will have
|
|
weird names like E::VB sometimes. The typeinfo function will always
|
|
be "E type_info function", or somesuch.
|
|
|
|
value_virtual_fn_field needs to be fixed so there are no failures for
|
|
virtual functions for C++ using g++.
|
|
|
|
Testsuite cases are the major priority right now for C++ support,
|
|
since i have to make a lot of changes that could potentially break
|
|
each other.

Symbol Support
|
|
==============
|
|
|
|
--
|
|
|
|
Investiagate ways of reducing memory.
|
|
|
|
--
|
|
|
|
Investigate ways of improving load time.
|
|
|
|
--
|
|
|
|
Testsuite Support
|
|
=================
|
|
|
|
There are never to many testcases.
|
|
|
|
--
|
|
|
|
Better thread testsuite.
|
|
|
|
--
|
|
|
|
Better C++ testsuite.

|
|
|
Architectural Changes: General
|
|
==============================
|
|
|
|
These are harder than simple cleanups / fixes and, consequently
|
|
involve more work. Typically an Architectural Change will be broken
|
|
down into a more digestible set of cleanups and fixes.
|
|
|
|
--
|
|
|
|
Architectural Change: Multi-arch et al.
|
|
=======================================
|
|
|
|
The long term objective is to remove all assumptions that there is a
|
|
single target with a single address space with a single instruction
|
|
set architecture and single application binary interface.
|
|
|
|
This is an ongoing effort. The first milestone is to enable
|
|
``multi-arch'' where by all architectural decisions are made at
|
|
runtime.
|
|
|
|
It should be noted that ``gdbarch'' is really ``gdbabi'' and
|
|
``gdbisa''. Once things are multi-arched breaking that down correctly
|
|
will become much easier.
|
|
|

|
|
|
|
Architectural Change: MI, LIBGDB and scripting languages
|
|
========================================================
|
|
|
|
See also architectural changes related to the event loop. LIBGDB
|
|
can't be finished until there is a generic event loop being used by
|
|
all targets.
|
|
|
|
The long term objective is it to be possible to integrate GDB into
|
|
scripting languages.
|
|
|
|
--
|
|
|
|
Architectural Change: Async
|
|
===========================
|
|
|
|
While GDB uses an event loop when prompting the user for input. That
|
|
event loop is not exploited by targets when they allow the target
|
|
program to continue. Typically targets still block in (target_wait())
|
|
until the program again halts.
|
|
|
|
The closest a target comes to supporting full asynchronous mode are
|
|
the remote targets ``async'' and ``extended-async''.
