This moves all the bitfields in struct cmd_list_element to be closer
together. This packs the structure somewhat better. On a 64 bit
machine, this simple rearrangement saves around 50k at startup.
2014-01-20 Tom Tromey <tromey@redhat.com>
* cli/cli-decode.h (struct cmd_list_element): Move all bitfields
together.
This changes various flags struct cmd_list_element into bitfields. In
general I think bitfields are cleaner than flag words, at least in a
case like this where there is no need to pass the flags around
independently of the enclosing struct.

bitfields.
* maint.c (maintenance_do_deprecate): Update.
* top.c (execute_command): Update.
This removes deprecated_set_hook. Insight was the last user of this
hook, but I recently checked in a patch to have it use the
command_param_changed observer instead.

I have a case that could use an exception for "unsupported feature".
I found UNSUPPORTED_ERROR, but looking deeper, I think as is, reusing
it for other things would be fragile. E.g., if the Python script
sourced by source_script_from_stream triggers any other missing
functionality that would result in UNSUPPORTED_ERROR being propagated
out to source_script_from_stream, that would confuse the error for
Python not being built into GDB.
This patch thus redoes things a little. Instead of using an exception
for the "No Python" scenario, check whether Python is configured in
before actually trying to source the file. It adds a new function
instead of using #ifdef HAVE_PYTHON directly, as that is better at
avoiding bitrot, as both Python and !Python paths are visible to the
compiler this way.
Tested on Fedora 17, with and without Python.

This fixes a couple of old "32x64" FIXME comments by using paddress
with current_gdbarch rather than hex_string and a cast to long.

This function provides the exact same functionality as extract_arg,
except that it takes a "const char**" instead of a "char **".
It allows us also to re-implement extract_arg almost as a simple
wrapper around the new function.
gdb/ChangeLog:
Pedro Alves <palves@redhat.com>
Joel Brobecker <brobecker@adacore.com>
* cli/cli-utils.h (extract_arg_const): Add declaration.
* cli/cli-utils.c (extract_arg_const): New function.
(extract_arg): Reimplement using extract_arg_const.
Consider the following example:
% gdb -q -batch -ex 'source nonexistant-file'
[nothing]
One would have at least expected the debugger to warn about
not finding the file, similar to the error shown when using
a more interactive mode. Eg:
(gdb) source nonexistant-file
nonexistant-file: No such file or directory.
Not raising an error appears to be intentional, presumably in order
to prevent this situation from stoping the execution of a GDB script.
But the lack of at least a warning makes it harder for a user to
diagnose any issue, if the file was expected to be there and readable.
This patch adds a warning in that case:
% gdb -q -batch -ex 'source nonexistant-file'
warning: nonexistant-file: No such file or directory.
gdb/ChangeLog:
* utils.h (perror_warning_with_name): Add declaration.
* utils.c (perror_warning_with_name): New function.
* cli/cli-cmds.c (source_script_with_search): Add call to
perror_warning_with_name if from_tty is nul.
gdb/testsuite/ChangeLog:
* gdb.base/source-nofile.gdb: New file.
* gdb.base/source.exp: Add two tests verifying the behavior when
the "source" command is given a non-existant filename.
This patch renames the "set/show remotebaud" commands into
"set/show serial baud", and moves its implementation into serial.c.
It also moves the "baud_rate" global from top.c to serial.c, where
the new code is being added (the alternative was to add an include
of target.h).
And to facilitate the transition to the new setting name, this
patch also preserves the old commands, and marks them as deprecated
to alert the users of the change.
gdb/ChangeLog:
* cli/cli-cmds.c (show_baud_rate): Moved to serial.c as
serial_baud_show_cmd.
(_initialize_cli_cmds): Delete the code creating the
"set/show remotebaud" commands.
* serial.c (baud_rate): Move here from top.c.
(serial_baud_show_cmd): Move here from cli/cli-cmds.c.
(_initialize_serial): Create "set/show serial baud" commands.
Add "set/show remotebaud" command aliases.
* top.c (baud_rate): Moved to serial.c.
* NEWS: Document the new "set/show serial baud" commands,
replacing "set/show remotebaud".
gdb/doc/ChangeLog:
* gdb.texinfo: Replace "set remotebaud" and "show remotebaud"
by "set serial baud" and "show serial baud" (resp) throughout.

I noticed the functions declared in cli-dump.h aren't used anywhere
outside cli-dump.c.
The original patch that introduced cli-dump.c didn't include this header:
http://sourceware.org/ml/gdb-patches/2002-03/msg00518.html
But for some reason that I couldn't find from reading the archives around
that patch's discussion, cli-dump.h was introduced in the final checkin,
at:
http://sourceware.org/ml/gdb-patches/2002-03/msg00596.html
There seems to be no point in keeping this around nowadays.

A following patch will want to make the "gdbinit" global array const.
As usual, that forces in a cascading series of const additions. This
patch preemptively does those. I went all the way up to constifying
catch_command_errors, but then that would require constifying
execute_command as well (which is a much more significant effort). So
as stop point, I found the cleanest would be to add a variant of
catch_command_errors that takes const args, and use that in the few
spots that needed it due to the the get_init_files constification.

read_command_lines_1 had some (IMNSHO) spaghetti-ish code for cleanup

Currently, several commands take "0" or "-1" to mean "unlimited".
"show" knows when to print "unlimited":
(gdb) show height
Number of lines gdb thinks are in a page is 45.
(gdb) set height 0
(gdb) show height
Number of lines gdb thinks are in a page is unlimited.
However, the user can't herself specify "unlimited" directly:
(gdb) set height unlimited
No symbol table is loaded. Use the "file" command.
(gdb)
This patch addresses that, by adjusting the set handler for all
integer/uinteger/zuinteger_unlimited commands to accept literal
"unlimited". It also installs a completer. Presently, we complete on
symbols by default, and at
<http://sourceware.org/ml/gdb-patches/2013-03/msg00864.html> I've
shown a WIP prototype that tried to keep that half working in these
commands. In the end, it turned out to be more complicated than
justifiable, IMO. It's super rare to want to pass the value of a
variable/symbol in the program to a GDB set/show knob. That'll still
work, it's just that we won't assist with completion anymore. This
patch just sticks with the simple, and completes on "unlimited", and
nothing else. This simplification means that
"set he<tab><tab>"
is all it takes to get to:
"set height unlimited"
The patch then goes through all integer/uinteger/zuinteger_unlimited
commands in the tree, and updates both the online help and the manual
to mention that "unlimited" is accepted in addition to 0/-1. In the
cases where the command had no online help text at all, this adds it.
I've tried to make the texts read in a way that "unlimited" is
suggested before "0" or "-1" is.

Gareth mentions in PR gdb/15275:
"The MI '-gdb-exit' command mi_cmd_gdb_exit() never calls disconnect_tracing()
and therefore exits correctly."
It should, so to get out of tfind mode, as quit may detach instead of
kill, and we don't want to confuse the memory/register accesses
etc. of the detach process. So we should push down the disconnect
tracing bits at least to quit_force. But we can't as is, as that
would swallow the error thrown by answering "no" to:
Trace is running but will stop on detach; detach anyway? (y or n)
So to address that, we split disconnect_tracing in two. One part that
does the query, and another part that does the rest, and we make
quit_force call the latter.
Looking at quit_force, it does several things, some of which are a bit
independent of the others. It first kills/detaches, and then writes
history, and then runs the final cleanups. It seems better to me to
do each of these things even if the previous thing throws. E.g., as
is, if something throws while detaching, then we skip writing history.

The range validation added by

Changes things to allow setting the command to INT_MAX or UINT_MAX
directly, with signed and unsigned commands respectively. However,
that went a little bit too far, as in the cases of var_integer and
var_uinteger, those values are actually implementation detail. It's
better to not expose them in the interface, and have users assume
those values mean "unlimited" too, so to be safer to expand the range
of the commands in the future if we want to. Yes, it's pedantic, and
it's not likely users actually will do this, but MI frontends and

This is a regression from 7.5, introduced/exposed by:
http://sourceware.org/ml/gdb-patches/2012-07/msg00259.html
There are a series of issues with this code.
It does:
unsigned int val = parse_and_eval_long (arg);
^^^^^^^^^^^^
(unsigned, usually 32-bit) while parse_and_eval_long returns a LONGEST
(usually 64-bit), so we lose precision without noticing:
(gdb) set remote hardware-watchpoint-limit 0x100000000
(gdb) show remote hardware-watchpoint-limit 0x100000000
The maximum number of target hardware watchpoints is 0.
While at it, print the invalid number with plongest, so the user sees
what GDB thought the number was:
(gdb) set remote hardware-watchpoint-limit 0x100000000
integer 4294967296 out of range
So with "set remote hardware-watchpoint-limit -1", val ends converted
to 0xffffffff, which then fails the
else if (val >= INT_MAX)
error (_("integer %u out of range"), val);
test.
Looking at that INT_MAX check, we forbid INT_MAX itself, but we
shouldn't, as that does fit in 'int' -- we want to forbid values
_greater_ than INT_MAX (and less than INT_MIN, while at it):
(gdb) set remote hardware-watchpoint-limit 2147483647
integer 2147483647 out of range
The same problem is in the new var_zuinteger_unlimited code, which
also uses "int" for variable.
Also, when printing a 'signed int', we should use %d, not %u.
This adds a couple regression tests. Not completely thorough in checking
all kinds of invalid input; I'm saving more exaustive testing around
zXXinteger commands for something like new test-assisting commands
like "maint test cmd-zinteger -1", where testing would focus on the
command types, and thus be independent of particular user commands of
particular GDB features.
Tested on x86_64 Fedora 17.

This is sort of a continuation of Keith's parse_exp_1 constification
patch. It started out by undoing these bits:
@@ -754,9 +754,12 @@ validate_actionline (char **line, struct
tmp_p = p;
for (loc = t->base.loc; loc; loc = loc->next)
{
- p = tmp_p;
- exp = parse_exp_1 (&p, loc->address,
+ const char *q;
+
+ q = tmp_p;
+ exp = parse_exp_1 (&q, loc->address,
block_for_pc (loc->address), 1);
+ p = (char *) q;
and progressively making more things const upwards, fixing fallout,
rinse repeat, until GDB built again (--enable-targets=all).
That ended up constifying lookup_cmd/add_cmd and (lots of) friends,
and the completers.
I didn't try to constify the command hooks themselves, because I know
upfront there are commands that write to the command string argument,
and I think I managed to stop at a nice non-hacky split point already.
I think the only non-really-super-obvious changes are
tracepoint.c:validate_actionline, and tracepoint.c:trace_dump_actions.
The rest is just mostly about 'char *' => 'const char *', 'char **'=>
'const char **', and the occasional (e.g., deprecated_cmd_warning)
case of 'char **'=> 'const char *', where/when I noticed that nothing
actually cares about the pointer to pointer output.
Tested on x86_64 Fedora 17, native and gdbserver.
