"dprintf" help.

This fixes PR cli/15603.
The bug here is that when a software watchpoint is being used, gdb
will stop responding to C-c. This is a regression caused by the
"catch signal" patch.
The problem is that software watchpoints always end up on the bpstat
list. However, this makes bpstat_explains_signal return
BPSTAT_SIGNAL_HIDE, causing infrun to think that the signal is not a
"random signal".
The fix is to change bpstat_explains_signal to handle this better. I
chose to do it in a "clean API" way, by passing the signal value to
bpstat_explains_signal and then adding an explains_signal method for
watchpoints, which handles the specifics.
Built and regtested on x86-64 Fedora 18.
New test case included.

breakpoint location.
If !PARSE_CONDITION_AND_THREAD, then ARG is just the location, nothing
else. The fact that the describing comment of create_breakpoint
doesn't mention this just looks like an oversight of when extra_string
was added. "parse_condition_and_thread" has been a misnomer ever
since extra_string was added -- better rename it avoid more confusion.
This makes it "parse_arg", as that'll remain stable even if/when more
explicit parameters are added.

If a tracepoint's actions list includes a while-stepping action, and
then the actions are changed to a list without any while-stepping
action, the tracepoint's step_count will be left with a stale value.
For example:

A related issue is that the "commands" command actually supports
setting commands to a range of breakpoints/tracepoints at once. But,
hacking "maint info breakpoints" to print t->step_count, reveals:
(gdb) trace main
Tracepoint 5 at 0x45a2ab: file ../../src/gdb/gdb.c, line 29.
(gdb) trace main
Note: breakpoint 5 also set at pc 0x45a2ab.
Tracepoint 6 at 0x45a2ab: file ../../src/gdb/gdb.c, line 29.
(gdb) commands 5-6
Type commands for breakpoint(s) 5-6, one per line.
End with a line saying just "end".
> while-stepping 5
>end
> end
(gdb) maint info breakpoints 5
Num Type Disp Enb Address What
5 tracepoint keep y 0x000000000045a2ab in main at ../../src/gdb/gdb.c:29 inf 1

(gdb) maint info breakpoints 6
Num Type Disp Enb Address What

step_count=0
^^^^^^^^^^^^
while-stepping 5
end
not installed on target
(gdb)
that tracepoint 6 doesn't end up with the correct step_count.
The issue is that here:
static void
do_map_commands_command (struct breakpoint *b, void *data)
{
struct commands_info *info = data;
if (info->cmd == NULL)
{
struct command_line *l;
if (info->control != NULL)
l = copy_command_lines (info->control->body_list[0]);
else
{
struct cleanup *old_chain;
char *str;
str = xstrprintf (_("Type commands for breakpoint(s) "
"%s, one per line."),
info->arg);
old_chain = make_cleanup (xfree, str);
l = read_command_lines (str,
info->from_tty, 1,
(is_tracepoint (b)
? check_tracepoint_command : 0),
b);
do_cleanups (old_chain);
}
info->cmd = alloc_counted_command_line (l);
}
validate_actionline is never called for tracepoints other than the
first (the copy_command_lines path). Right below, we have:
/* If a breakpoint was on the list more than once, we don't need to
do anything. */
if (b->commands != info->cmd)
{
validate_commands_for_breakpoint (b, info->cmd->commands);
incref_counted_command_line (info->cmd);
decref_counted_command_line (&b->commands);
b->commands = info->cmd;
observer_notify_breakpoint_modified (b);
}
And validate_commands_for_breakpoint looks like the right place to put
a call; if we reset step_count there too, we have a nice central fix
for the first issue as well, because trace_actions_command calls
breakpoint_set_commands that also calls
validate_commands_for_breakpoint.
We end up calling validate_actionline twice for the first tracepoint,
since read_command_lines calls it too, through
check_tracepoint_command, but that should be harmless.

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)

observer_notify_breakpoints_changed calls. All, except the
init_raw_breakpoint one. But that one is actually wrong. The
breakpoint is being constructed at that point, and hasn't been placed
on the breakpoint chain yet. It would be better placed in
install_breakpoint, and I actually started out that way. But once the
annotate_breakpoints_changed are parallel to the observer calls, we
can fully move annotations to observers too.
One issue is that this changes the order of annotations a bit.
Before, we'd emit the annotation, and after call "mention()" on the
breakpoint (which prints the breakpoint number, etc.). But, we call
the observers _after_ mention is called, so the annotation output will
change a little:
void
install_breakpoint (int internal, struct breakpoint *b, int update_gll)
{
add_to_breakpoint_chain (b);
set_breakpoint_number (internal, b);
if (is_tracepoint (b))
set_tracepoint_count (breakpoint_count);
if (!internal)
mention (b);
observer_notify_breakpoint_created (b);
if (update_gll)
update_global_location_list (1);
}
I believe this order doesn't really matter (the frontend needs to wait
for the prompt anyway), so I just adjust the expected output in the
tests. Emacs in annotations mode doesn't seem to complain. Couple
that with the previous patch that suppressed duplicated annotations,
and, the fact that some annotations calls were actually missing (were
we do have observer calls), more changes to the tests are needed
anyway.

suppress multiple breakpoints-invalid annotations when the ignore
count of a breakpoint changes, up until the target actually stops.
But, the code is bogus:
void
annotate_breakpoints_changed (void)
{
if (annotation_level == 2)
{
target_terminal_ours ();
printf_unfiltered (("\n\032\032breakpoints-invalid\n"));
if (ignore_count_changed)
ignore_count_changed = 0; /* Avoid multiple break annotations. */
}
}
The "ignore_count_changed" flag isn't actually guarding the output of
the annotation at all. It would have been better written something
like:
void
annotate_breakpoints_changed (void)
{
if (annotation_level == 2 && !ignore_count_changed)
{
target_terminal_ours ();
printf_unfiltered (("\n\032\032breakpoints-invalid\n"));
ignore_count_changed = 0; /* Avoid multiple break annotations. */
}
}
but, it wasn't. AFAICS, that goes all the way back to the original
patch'es submission and check in, at
<http://sourceware.org/ml/gdb-patches/1999-q4/msg00106.html>. I
looked a tar of HP's wdb from 1999, and even though that contains
local changes in the annotate code, this suppression seems borked
there too to me.
The original patch added a test to supposedly exercise this
suppression, but, it actually doesn't. It merely tests that
"breakpoints-invalid" is output after "stopped", but doesn't check
whether the duplicates supression actually works (IOW, check that only
_one_ annotation is seen). I was going to simply delete the tests
too, but a following patch will eliminate the duplicates in a
different way (which I needed for a different reason), so instead, I'm
making the tests actually fail if a duplicate annotation is seen.
Worry not, the test doesn't actually fail! The reason is that
breakpoint.c does:
else if (b->ignore_count > 0)
{
b->ignore_count--;
annotate_ignore_count_change ();
bs->stop = 0;
/* Increase the hit count even though we don't stop. */
++(b->hit_count);
observer_notify_breakpoint_modified (b);
}
where the annotate_ignore_count_change call is meant to inform the
"breakpoint_modified" annotation observer to ignore the notification.
All sounds good. But, the trouble is that nowadays annotate.c only
installs the observers if GDB is started with annotations enabled with
a command line option (gdb --annotate=2):
void
_initialize_annotate (void)
{
if (annotation_level == 2)
{
observer_attach_breakpoint_deleted (breakpoint_changed);
observer_attach_breakpoint_modified (breakpoint_changed);
}
}
and annota1.exp, to enable annotations, starts GDB normally, and
afterwards does "set annotate 2", so the observers aren't installed
when annota1.exp is run, and therefore changing the ignore count isn't
triggering any annotation at all...
