Below is a list of problems identified during the GDB 5.0 release
|
|
|
|
cycle. People hope to have these problems fixed in a follow-on
|
|
|

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:

I know there are problems with single stepping through signal
|
|
|
|
handlers. These problems were present in 4.18. They were just masked
|
|
|
|
because 4.18 failed to recognize signal handlers. Fixing it is not
|
|
|
|
easy, and will require changes to handle_inferior_event(), that I
|
|
|
|
prefer not to make before the 5.0 release.

Code Cleanups: General
|
|
|
|
======================
|
|
|
|
|
|
|
|
The following are more general cleanups and fixes. They are not tied
|
|
|
|
to any specific release.
|

|
|
|
Eliminate more compiler warnings.
|
|
|
|
|
|
|
|
Of course there also needs to be the usual debate over which warnings
|
|
|
|
are valid and how to best go about this.
|
|
|
|
|
|
|
|
One method: choose a single option; get agreement that it is
|
|
|
|
reasonable; try it out to see if there isn't anything silly about it
|
|
|
|
(-Wunused-parameters is an example of that) then incrementally hack
|
|
|
|
away.
|
|
|
|
|
|
|
|
The other method is to enable all warnings and eliminate them from one
|
|
|
|
file at a time.

Rationalize the host-endian code (grep for HOST_BYTE_ORDER).
|
|

|
|
|
|
|
At present defs.h includes <endian.h> (which is linux specific) yet
|
|
|
|
almost nothing depends on it. Suggest "gdb_endian.h" which can also
|
|
|
|
handle <machine/endian.h> and only include that where it is really
|
|
|
|
needed.

return value.

Rationalize use of floatformat_unknown in GDB sources.
|

Eliminate abort ().
|
|
|
|
|
|
|
|
GDB should never abort. GDB should either throw ``error ()'' or
|
|
|
|
``internal_error ()''. Better still GDB should naturally unwind with
|
|
|
|
an error status.

Rationalize floatformat_to_double() vs floatformat_to_doublest().
|
|
|
|
|
|
|
|
Looks like GDB migrated floatformat_to_double() to libiberty but then

|
|
|
|
several bug fixes.

When the srcware tree is configured with --enable-shared, the `expect'

program won't run properly. Jim Wilson found out gdb has a local hack
|

to set LD_LIBRARY_PATH, but, AFAIK, no other project has been hacked

similarly.

Some of these (*m.h) would be added to the generated config.h. That
|
|
|
|
in turn would fix a long standing bug where by the build process many
|
|
|
|
not notice a changed tm.h file. Since everything depends on config.h,
|
|
|
|
a change to *m.h forces a change to config.h and, consequently forces
|
|
|
|
a rebuild.

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 did not work

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.

GDB doesn't recover gracefully from remote protocol errors.

|

2000-05-30 08:52:57 +00:00

|
|
GDB wasn't checking for NAKs from the remote target. Instead a NAK is
|
|
|
|
ignored and a timeout is required before GDB retries. A pre-cursor to
|
|
|
|
fixing this this is making GDB's remote protocol packet more robust.
|
|
|
|
|
|
|
|
While downloading to a remote protocol target, gdb ignores packet
|
|
|
|
errors in so far as it will continue to edownload with chunk N+1 even
|
|
|
|
if chunk N was not correctly sent. This causes gdb.base/remote.exp to
|
|
|
|
take a painfully long time to run. As a PS that test needs to be
|
|
|
|
fixed so that it builds on 16 bit machines.

If / when GDB starts to support the debugging of multi-processor
|
|
|
|
(rather than multi-thread) applications the symtab code will need to
|
|
|
|
be updated a little so that several independant symbol tables are
|
|
|
|
active at a given time.
|
|
|
|
|
|
|
|
The other interesting change is a clarification of the exact meaning
|
|
|
|
of CORE_ADDR and that has had consequences for a few targets (that
|
|
|
|
were abusing that data type).

Testsuite Support

Separate out tests that involve the floating point (FP).
|
|
|
|
|
|
|
|
(Something for people brining up new targets). FP and non-fp tests
|
|
|
|
are combined. I think there should be set of basic tests that
|
|
|
|
exercise pure integer support and then a more expanded set that
|
|
|
|
exercise FP and FP/integer interactions.
|
|
|
|
|
|
|
|
As an example, the MIPS, for n32 as problems with passing FP's and
|
|
|
|
structs. Since most inferior call tests include FP it is difficult to
|
|
|
|
determine of the integer tests are ok.

Architectural Changes: General
|

|
|
==============================
|
2000-05-16 09:00:20 +00:00
|
|
|
|
|
|
|
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.

Cleanup software single step.
|
|
|
|
|
|
|
|
At present many targets implement software single step by directly
|
|
|
|
blatting memory (see rs6000-tdep.c). Those targets should register
|
|
|
|
the applicable breakpoints using the breakpoint framework. Perhaphs a
|
|
|
|
new internal breakpoint class ``step'' is needed.

|
Replace READ_FP() with FRAME_HANDLE().
|
|
|
|
|
|
|
|
READ_FP() is a hangover from the days of the vax when the ABI really
|
|
|
|
did have a frame pointer register. Modern architectures typically
|
|
|
|
construct a virtual frame-handle from the stack pointer and various
|
|
|
|
other bits of string.
|
|
|
|
|
|
|
|
Unfortunatly GDB still treats this synthetic FP register as though it
|
|
|
|
is real. That in turn really confuses users (arm and ``print $fp'' VS
|
|
|
|
``info registers fp''). The synthetic FP should be separated out of
|
|
|
|
the true register set presented to the user.

Register Cache Cleanup (below from Andrew Cagney)
|
|
|
|
|
|
|
|
I would depict the current register architecture as something like:
|
|
|
|
|
|
|
|
High GDB --> Low GDB
|
|
|
|
| |
|
|
|
|
\|/ \|/
|
|
|
|
--- REG NR -----
|
|
|
|
|
|
|
|
|
register + REGISTER_BYTE(reg_nr)
|
|
|
|
|
|
|
|
|
\|/
|
|
|
|
-------------------------
|
|
|
|
| extern register[] |
|
|
|
|
-------------------------
|
|
|
|
|
|
|
|
where neither the high (valops.c et.al.) or low gdb (*-tdep.c) are
|
|
|
|
really clear on what mechanisms they should be using to manipulate that
|
|
|
|
buffer. Further, much code assumes, dangerously, that registers are
|
|
|
|
contigious. Having got mips-tdep.c to support multiple ABIs, believe
|
|
|
|
me, that is a bad assumption. Finally, that register cache layout is
|
|
|
|
determined by the current remote/local target and _not_ the less
|
|
|
|
specific target ISA. In fact, in many cases it is determined by the
|
|
|
|
somewhat arbitrary layout of the [gG] packets!
|
|
|
|
|
|
|
|
|
|
|
|
How I would like the register file to work is more like:
|
|
|
|
|
|
|
|
|
|
|
|
High GDB
|
|
|
|
|
|
|
|
|
\|/
|
|
|
|
pseudo reg-nr
|
|
|
|
|
|
|
|
|
map pseudo <->
|
|
|
|
random cache
|
|
|
|
bytes
|
|
|
|
|
|
|
|
|
\|/
|
|
|
|
------------
|
|
|
|
| register |
|
|
|
|
| cache |
|
|
|
|
------------
|
|
|
|
/|\
|
|
|
|
|
|
|
|
|
map random cache
|
|
|
|
bytes to target
|
|
|
|
dependant i-face
|
|
|
|
/|\
|
|
|
|
|
|
|
|
|
target dependant
|
|
|
|
such as [gG] packet
|
|
|
|
or ptrace buffer
|
|
|
|
|
|
|
|
The main objectives being:
|
|
|
|
|
|
|
|
o a clear separation between the low
|
|
|
|
level target and the high level GDB
|
|
|
|
|
|
|
|
o a mechanism that solves the general
|
|
|
|
problem of register aliases, overlaps
|
|
|
|
etc instead of treating them as optional
|
|
|
|
extras that can be wedged in as an after
|
|
|
|
thought (that is a reasonable description
|
|
|
|
of the current code).
|
|
|
|
|
|
|
|
Identify then solve the hard case and the
|
|
|
|
rest just falls out. GDB solved the easy
|
|
|
|
case and then tried to ignore the real
|
|
|
|
world :-)
|
|
|
|
|
|
|
|
o a removal of the assumption that the
|
|
|
|
mapping between the register cache
|
|
|
|
and virtual registers is largely static.
|
|
|
|
If you flip the USR/SSR stack register
|
|
|
|
select bit in the status-register then
|
|
|
|
the corresponding stack registers should
|
|
|
|
reflect the change.
|
|
|
|
|
|
|
|
o a mechanism that clearly separates the
|
|
|
|
gdb internal register cache from any
|
|
|
|
target (not architecture) dependant
|
|
|
|
specifics such as [gG] packets.
|
|
|
|
|
|
|
|
Of course, like anything, it sounds good in theory. In reality, it
|
|
|
|
would have to contend with many<->many relationships at both the
|
|
|
|
virt<->cache and cache<->target level. For instance:
|
|
|
|
|
|
|
|
virt<->cache
|
|
|
|
Modifying an mmx register may involve
|
|
|
|
scattering values across both FP and
|
|
|
|
mmpx specific parts of a buffer
|
|
|
|
|
|
|
|
cache<->target
|
|
|
|
When writing back a SP it may need to
|
|
|
|
both be written to both SP and USP.
|
|
|
|
|
|
|
|
|
|
|
|
Hmm,
|
|
|
|
|
|
|
|
Rather than let this like the last time it was discussed, just slip, I'm
|
|
|
|
first going to add this e-mail (+ references) to TODO. I'd then like to
|
|
|
|
sketch out a broad strategy I think could get us there.
|
|
|
|
|
|
|
|
|
|
|
|
First thing I'd suggest is separating out the ``extern registers[]''
|
|
|
|
code so that we can at least identify what is using it. At present
|
|
|
|
things are scattered across many files. That way we can at least
|
|
|
|
pretend that there is a cache instead of a global array :-)
|
|
|
|
|
|
|
|
I'd then suggest someone putting up a proposal for the pseudo-reg /
|
|
|
|
high-level side interface so that code can be adopted to it. For old
|
|
|
|
code, initially a blanket rename of write_register_bytes() to
|
|
|
|
deprecated_write_register_bytes() would help.
|
|
|
|
|
|
|
|
Following that would, finaly be the corresponding changes to the target.

Check that GDB can handle all BFD architectures (Andrew Cagney)

There should be a test that checks that BFD/GDB are in sync with

regard to architecture changes. Something like a test that first

|
queries GDB for all supported architectures and then feeds each back

to GDB.. Anyone interested in learning how to write tests? :-)

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.
|
2000-05-15 23:10:56 +00:00
|
|
|
|
2000-05-30 08:52:57 +00:00
|
|
|
This is an ongoing effort. The first milestone is to enable
|
|
|
|
``multi-arch'' where by all architectural decisions are made at
|
|
|
|
runtime.

|
|
|

2000-05-30 08:52:57 +00:00
|
|
|
It should be noted that ``gdbarch'' is really ``gdbabi'' and
|
|
|
|
``gdbisa''. Once things are multi-arched breaking that down correctly
|
|
|
|
will become much easier.

Fix target_signal_from_host() etc.
|
|
|
|
|
|
|

The name is wrong for starters. ``target_signal'' should probably be
|
|
|
|
``gdb_signal''. ``from_host'' should be ``from_target_signal''.
|
|
|
|
After that it needs to be multi-arched and made independant of any

|
|
host signal numbering.

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.

Re-do GDB's output pager.
|
|
|
|
|
|
|
|
GDB's output pager still relies on people correctly using *_filtered
|
|
|
|
for gdb_stdout and *_unfiltered for gdb_stdlog / gdb_stderr.
|
|
|
|
Hopefully, with all normal output going to gdb_stdout, the pager can
|
|
|
|
just look at the ui_file that the output is on and then use that to
|
|
|
|
decide what to do about paging. Sounds good in theory.

Convert MI into libgdb
|
|

MI provides a text interface into what should be many of the libgdb
|
|
|
|
functions. The implementation of those functions should be separated
|
|
|
|
into the MI interface and the functions proper. Those functions being
|
|
|
|
moved to gdb/lib say.

MI's input does not use buffering.
|
|
|
|
|
|
|
|
At present the MI interface reads raw characters of from an unbuffered
|
|
|
|
FD. This is to avoid several nasty buffer/race conditions. That code
|
|
|
|
should be changed so that it registers its self with the event loop
|
|
|
|
(on the input FD) and then push commands up to MI as they arrive.
|
|
|
|
|
|
|
|
The serial code already does this.

assignments. A way of restricting the expression parser so that such
|
|

Remove sideffects from libgdb breakpoint create function.
|
|
|
|
|
|
|
|
The user can use the CLI to create a breakpoint with partial
|
|
|
|
information - no file (gdb would use the file from the last
|
|
|
|
breakpoint).
|
|
|
|
|
|
|
|
The libgdb interface currently affects that environment which can lead
|
|
|
|
to confusion when a user is setting breakpoints via both the MI and
|
|
|
|
the CLI.
|
|
|
|
|
|
|
|
This is also a good example of how getting the CLI ``right'' will be
|
|
|
|
hard.

The way GDB throws errors and records them needs a re-think. ui_out

handles the correct output well. It doesn't resolve what to do with

output / error-messages when things go wrong.

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''.

|
|
|
|
|
|
|
Fix implementation of ``target xxx''.
|
|
|
|
|
|
|
|
At present when the user specifies ``target xxxx'', the CLI maps that
|
|
|
|
directly onto a target open method. It is then assumed that the
|
|
|
|
target open method should do all sorts of complicated things as this
|
|
|
|
is the only chance it has. Check how the various remote targets
|
|
|
|
duplicate the target operations. Check also how the various targets
|
|
|
|
behave differently for purely arbitrary reasons.
|
|
|
|
|
|
|
|
What should happen is that ``target xxxx'' should call a generic
|
|
|
|
``target'' function and that should then co-ordinate the opening of
|
|
|
|
``xxxx''. This becomes especially important when you're trying to
|
|
|
|
open an asynchronous target that may need to perform background tasks
|
|
|
|
as part of the ``attach'' phase.
|
|
|
|
|
|
|
|
Unfortunatly, due to limitations in the old/creaking command.h
|
|
|
|
interface, that isn't possible. The function being called isn't told
|
|
|
|
of the ``xxx'' or any other context information.
|
|
|
|
|
|
|
|
Consequently a precursor to fixing ``target xxxx'' is to clean up the
|
|
|
|
CLI code so that it passes to the callback function (attatched to a
|
|
|
|
command) useful information such as the actual command and a context
|
|
|
|
for that command. Other changes such as making ``struct command''
|
|
|
|
opaque may also help.

|
|
|
Make "target xxx" command interruptible.
|
|
|
|
|
|
|
|
As things become async this becomes possible. A target would start
|
|
|
|
the connect and then return control to the event loop. A cntrl-c
|
|
|
|
would notify the target that the operation is to be abandoned and the
|
|
|
|
target code could respond.

The benefits on this one are thought to be marginal - GDBs design

means that unused parameters are very common. GCC 3.0 will also

include the option -Wno-unused-parameter which means that ``-Wall

exactly where the libraries will be loaded. E.g. "b perror" before running

re-evaluation" after new symbols are loaded.

Get SECT_OFF_TEXT stuff out of objfile_relocate (might be needed to
|
|
|
|
get RS/6000 to work right, might not be immediately relevant).

Work out some kind of way to allow running the inferior to be done as
|
|
|
|
a sub-execution of, eg. breakpoint command lists. Currently running
|
|
|
|
the inferior interupts any command list execution. This would require
|
|
|
|
some rewriting of wait_for_inferior & friends, and hence should
|
|
|
|
probably be done in concert with the above.

|

Modify the handling of symbols grouped through BINCL/EINCL stabs to
|
|
|
|
allocate a partial symtab for each BINCL/EINCL grouping. This will
|
|
|
|
seriously decrease the size of inter-psymtab dependencies and hence
|
|
|
|
lessen the amount that needs to be read in when a new source file is
|
|
|
|
accessed.

Add a command for searching memory, a la adb. It specifies size,
|
|
|
|
mask, value, start address. ADB searches until it finds it or hits
|
|
|
|
an error (or is interrupted).

going to implement.
