If GDB reports a watchpoint hit, and then the next event is not
TARGET_WAITKIND_STOPPED, but instead some event for which there's a
catchpoint, such that GDB calls bpstat_stop_status, GDB mistakenly
thinks the watchpoint triggered. Vis, using foll-fork.c:
(gdb) awatch v
Hardware access (read/write) watchpoint 2: v
(gdb) catch fork
Catchpoint 3 (fork)
(gdb) c
Continuing.
Hardware access (read/write) watchpoint 2: v
Old value = 0
New value = 5
main () at gdb.base/foll-fork.c:16
16 pid = fork ();
(gdb)
Continuing.
Hardware access (read/write) watchpoint 2: v <<<<
<<<< these lines are spurious
Value = 5 <<<<
Catchpoint 3 (forked process 1712369), arch_fork (ctid=0x7ffff7fa4810) at arch-fork.h:49
49 arch-fork.h: No such file or directory.
(gdb)
The problem is that when we handle the fork event, nothing called
watchpoints_triggered before calling bpstat_stop_status. Thus, each
watchpoint's watchpoint_triggered field was still set to
watch_triggered_yes from the previous (real) watchpoint stop.
watchpoint_triggered is only current called in the handle_signal_stop
path, when handling TARGET_WAITKIND_STOPPED.
This fixes it by adding watchpoint_triggered calls in the other events
paths that call bpstat_stop_status. But instead of adding them
explicitly, it adds a new function bpstat_stop_status_nowatch that
wraps bpstat_stop_status and calls watchpoint_triggered, and then
replaces most calls to bpstat_stop_status with calls to
bpstat_stop_status_nowatch.
This required constifying watchpoints_triggered.
New test included, which fails without the fix.

While working on target_waitstatus changes, I noticed a few places where
const target_waitstatus objects could be passed by reference instead of
by pointers. And in some cases, places where a target_waitstatus could
be passed as const, but was not. Convert them as much as possible.

I don't find that the bpstat typedef, which hides a pointer, is
particularly useful. In fact, it confused me many times, and I just see
it as something to remember that adds cognitive load. Also, with C++,
we might want to be able to pass bpstats objects by const-reference, not
necessarily by pointer.
So, remove the bpstat typedef and rename struct bpstats to bpstat (since
it represents one bpstat, it makes sense that it is singular).

I don't understand what the sfunc function type in
cmd_list_element::function is for. Compared to cmd_simple_func_ftype,
it has an extra cmd_list_element parameter, giving the callback access
to the cmd_list_element for the command being invoked. This allows
registering the same callback with many commands, and alter the behavior
using the cmd_list_element's context.
From the comment in cmd_list_element, it sounds like at some point it
was the callback function type for set and show functions, hence the
"s". But nowadays, it's used for many more commands that need to access
the cmd_list_element object (see add_catch_command for example).
I don't really see the point of having sfunc at all, since do_sfunc is
just a trivial shim that changes the order of the arguments. All
commands using sfunc could just as well set cmd_list_element::func to
their callback directly.
Therefore, remove the sfunc field in cmd_list_element and everything
that goes with it. Rename cmd_const_sfunc_ftype to cmd_func_ftype and
use it for cmd_list_element::func, as well as for the add_setshow
commands.

I was always a bit confused by next_adapter, because it kind of mixes
the element type and the iterator type. In reality, it is not much more
than a class that wraps two iterators (begin and end). However, it
assumes that:
- you can construct the begin iterator by passing a pointer to the
first element of the iterable
- you can default-construct iterator to make the end iterator
I think that by generalizing it a little bit, we can re-use it at more
places.
Rename it to "iterator_range". I think it describes a bit better: it's
a range made by wrapping a begin and end iterator. Move it to its own
file, since it's not related to next_iterator anymore.
iterator_range has two constructors. The variadic one, where arguments
are forwarded to construct the underlying begin iterator. The end
iterator is constructed through default construction. This is a
generalization of what we have today.
There is another constructor which receives already constructed begin
and end iterators, useful if the end iterator can't be obtained by
default-construction. Or, if you wanted to make a range that does not
end at the end of the container, you could pass any iterator as the
"end".
This generalization allows removing some "range" classes, like
all_inferiors_range. These classes existed only to pass some arguments
when constructing the begin iterator. With iterator_range, those same
arguments are passed to the iterator_range constructed and then
forwarded to the constructed begin iterator.
There is a small functional difference in how iterator_range works
compared to next_adapter. next_adapter stored the pointer it received
as argument and constructeur an iterator in the `begin` method.
iterator_range constructs the begin iterator and stores it as a member.
Its `begin` method returns a copy of that iterator.
With just iterator_range, uses of next_adapter<foo> would be replaced
with:
using foo_iterator = next_iterator<foo>;
using foo_range = iterator_range<foo_iterator>;
However, I added a `next_range` wrapper as a direct replacement for
next_adapter<foo>. IMO, next_range is a slightly better name than
next_adapter.
The rest of the changes are applications of this new class.

Now that we have range functions that let us use ranged for loops, we
can remove iterate_over_breakpoints in favor of those, which are easier
to read and write. This requires exposing the declaration of
all_breakpoints and all_breakpoints_safe in breakpoint.h, as well as the
supporting types.
Change some users of iterate_over_breakpoints to use all_breakpoints,
when they don't need to delete the breakpoint, and all_breakpoints_safe
otherwise.

Add the breakpoint::locations method, which returns a range that can be
used to iterate over a breakpoint's locations. This shortens
for (bp_location *loc = b->loc; loc != nullptr; loc = loc->next)
into
for (bp_location *loc : b->locations ())
Change all the places that I found that could use it.

Same idea as the previous patches, but to replace the ALL_TRACEPOINTS
macro. Define a new filtered_iterator that only keeps the breakpoints
for which is_tracepoint returns true (just like the macro did).
I would have like to make it so tracepoint_range yields some
`tracepoint *` instead of some `breakpoint *`, that would help simplify
the callers, who wouldn't have to do the cast themselves. But I didn't
find an obvious way to do it. It can always be added later.
It turns out there is already an all_tracepoints function, which returns
a vector containing all the breakpoints that are tracepoint. Remove it,
most users will just work seamlessly with the new function. The
exception is start_tracing, which iterated multiple times on the vector.
Adapt this one so it iterates multiple times on the returned range.
Since the existing users of all_tracepoints are outside of breakpoint.c,
this requires defining all_tracepoints and a few supporting types in
breakpoint.h. So, move breakpoint_iterator from breakpoint.c to
breakpoint.h.
gdb/ChangeLog:
* breakpoint.h (all_tracepoints): Remove.
(breakpoint_iterator): Move here.

all_tracepoints.

The 'create_breakpoint' function takes a 'parse_extra' argument that
determines whether the condition, thread, and force-condition
specifiers should be parsed from the extra string or be used from the
function arguments. However, for the case when 'parse_extra' is
false, there is no way to pass the force-condition specifier. This
patch adds it as a new argument.
Also, in the case when parse_extra is false, the current behavior is
as if the condition is being forced. This is a bug. The default
behavior should reject the breakpoint. See below for a demo of this
incorrect behavior. (The MI command '-break-insert' uses the
'create_breakpoint' function with parse_extra=0.)

After applying this patch, we get the behavior below:

Many spots incorrectly use only spaces for indentation (for example,
there are a lot of spots in ada-lang.c). I've always found it awkward
when I needed to edit one of these spots: do I keep the original wrong
indentation, or do I fix it? What if the lines around it are also
wrong, do I fix them too? I probably don't want to fix them in the same
patch, to avoid adding noise to my patch.
So I propose to fix as much as possible once and for all (hopefully).
One typical counter argument for this is that it makes code archeology
more difficult, because git-blame will show this commit as the last
change for these lines. My counter counter argument is: when
git-blaming, you often need to do "blame the file at the parent commit"
anyway, to go past some other refactor that touched the line you are
interested in, but is not the change you are looking for. So you
already need a somewhat efficient way to do this.
Using some interactive tool, rather than plain git-blame, makes this
trivial. For example, I use "tig blame <file>", where going back past
the commit that changed the currently selected line is one keystroke.
It looks like Magit in Emacs does it too (though I've never used it).
Web viewers of Github and Gitlab do it too. My point is that it won't
really make archeology more difficult.
The other typical counter argument is that it will cause conflicts with
existing patches. That's true... but it's a one time cost, and those
are not conflicts that are difficult to resolve. I have also tried "git
rebase --ignore-whitespace", it seems to work well. Although that will
re-introduce the faulty indentation, so one needs to take care of fixing
the indentation in the patch after that (which is easy).

The previous patch made it possible to define a condition if it's
valid at some locations. If the condition is invalid at all of the
locations, it's rejected. However, there may be cases where the user
knows the condition *will* be valid at a location in the future,
e.g. due to a shared library load.
To make it possible that such condition can be defined, this patch
adds an optional '-force' flag to the 'condition' command, and,
respectively, a '-force-condition' flag to the 'break'command. When
the force flag is passed, the condition is not rejected even when it
is invalid for all the current locations (note that all the locations
would be internally disabled in this case).
For instance:
(gdb) break test.c:5
Breakpoint 1 at 0x1155: file test.c, line 5.
(gdb) cond 1 foo == 42
No symbol "foo" in current context.
Defining the condition was not possible because 'foo' is not
available. The user can override this behavior with the '-force'
flag:
(gdb) cond -force 1 foo == 42
warning: failed to validate condition at location 1.1, disabling:
No symbol "foo" in current context.
(gdb) info breakpoints
Num Type Disp Enb Address What
1 breakpoint keep y <MULTIPLE>
stop only if foo == 42
1.1 N 0x0000000000001155 in main at test.c:5
Now the condition is accepted, but the location is automatically
disabled. If a future location has a context in which 'foo' is
available, that location would be enabled.
For the 'break' command, -force-condition has the same result:
(gdb) break test.c:5 -force-condition if foo == 42
warning: failed to validate condition at location 0x1169, disabling:
No symbol "foo" in current context.
Breakpoint 1 at 0x1169: file test.c, line 5.

Currently, for a conditional breakpoint, GDB checks if the condition
can be evaluated in the context of the first symtab and line (SAL).
In case of an error, defining the conditional breakpoint is aborted.
This prevents having a conditional breakpoint whose condition may
actually be meaningful for some of the location contexts. This patch
makes it possible to define conditional BPs by checking all location
contexts. If the condition is meaningful for even one context, the
breakpoint is defined. The locations for which the condition gives
errors are disabled.
The bp_location struct is introduced a new field, 'disabled_by_cond'.
This field denotes whether the location is disabled automatically
because the condition was non-evaluatable. Disabled-by-cond locations
cannot be enabled by the user. But locations that are not
disabled-by-cond can be enabled/disabled by the user manually as
before.
For a concrete example, consider 3 contexts of a function 'func'.
class Base
{
public:
int b = 20;
void func () {}
};
class A : public Base
{
public:
int a = 10;
void func () {}
};
class C : public Base
{
public:
int c = 30;
void func () {}
};
Note that
* the variable 'a' is defined only in the context of A::func.
* the variable 'c' is defined only in the context of C::func.
* the variable 'b' is defined in all the three contexts.
With the existing GDB, it's not possible to define a conditional
breakpoint at 'func' if the condition refers to 'a' or 'c':
(gdb) break func if a == 10
No symbol "a" in current context.
(gdb) break func if c == 30
No symbol "c" in current context.
(gdb) info breakpoints
No breakpoints or watchpoints.
With this patch, it becomes possible:
(gdb) break func if a == 10
warning: failed to validate condition at location 1, disabling:
No symbol "a" in current context.
warning: failed to validate condition at location 3, disabling:
No symbol "a" in current context.
Breakpoint 1 at 0x11b6: func. (3 locations)
(gdb) break func if c == 30
Note: breakpoint 1 also set at pc 0x11ce.
Note: breakpoint 1 also set at pc 0x11c2.
Note: breakpoint 1 also set at pc 0x11b6.
warning: failed to validate condition at location 1, disabling:
No symbol "c" in current context.
warning: failed to validate condition at location 2, disabling:
No symbol "c" in current context.
Breakpoint 2 at 0x11b6: func. (3 locations)

(*): Breakpoint condition is invalid at this location.
Here, uppercase 'N' denotes that the location is disabled because of
the invalid condition, as mentioned with a footnote in the legend of
the table. Locations that are disabled by the user are still denoted
with lowercase 'n'. Executing the code hits the breakpoints 1.2 and
2.3 as expected.
Defining a condition on an unconditional breakpoint gives the same
behavior above:
(gdb) break func
Breakpoint 1 at 0x11b6: func. (3 locations)
(gdb) cond 1 a == 10
warning: failed to validate condition at location 1.1, disabling:

Consider test-case test.c:
...
$ cat test.c
int main (void) {
return 0;
L1:
(void)0;
}
...
Compiled with debug info:
...
$ gcc test.c -g
...
When attempting to set a breakpoint at L1, which is a label without address:
...
<1><f4>: Abbrev Number: 2 (DW_TAG_subprogram)
<f5> DW_AT_name : main
<2><115>: Abbrev Number: 3 (DW_TAG_label)
<116> DW_AT_name : L1
<119> DW_AT_decl_file : 1
<11a> DW_AT_decl_line : 5
<2><11b>: Abbrev Number: 0
...
we run into an internal-error:
...
$ gdb -batch a.out -ex "b main:L1"
linespec.c:3233: internal-error: void \
decode_line_full(const event_location*, int, program_space*, symtab*, \
int, linespec_result*, const char*, const char*): \
Assertion `result.size () == 1 || canonical->pre_expanded' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
...
Fix this by detecting the error condition in decode_line_full instead, and
throwing an error, such that we have instead:
...
(gdb) b main:L1
Location main:L1 not available
(gdb)
...
Unfortunately, to call event_location_to_string, which is used to get the
location name in the error message, we need to pass a non-const struct
event_location, because the call may cache the string in the struct (See
EL_STRING). So, we change the prototype of decode_line_full accordingly, and
everywhere this propages to.
Tested on x86_64-linux.

New in v3:
- Code cleanups based on reviews.
New in v2:
- Fixed misc problems based on reviews.
- Switched to using gdbarch_program_breakpoint_here_p as opposed to
gdbarch_insn_is_breakpoint.
- Fixed matching of brk instructions. Previously the mask was incorrect, which
was showing up as a few failures in the testsuite. Now it is clean.
- New testcase (separate patch).
- Moved program_breakpoint_here () to arch-utils.c and made it the default
implementation of gdbarch_program_breakpoint_here_p.

It was reported to me that program breakpoints (permanent ones inserted into
the code itself) other than the one GDB uses for AArch64 (0xd4200000) do not
generate visible stops when continuing, and GDB will continue spinning
infinitely.
This happens because GDB, upon hitting one of those program breakpoints, thinks
the SIGTRAP came from a delayed breakpoint hit...

Otherwise GDB will keep trying to resume the inferior and will keep
seeing the SIGTRAP's, without stopping.
To the user it appears GDB has gone into an infinite loop, interruptible only
by Ctrl-C.
Also, windbg seems to use a different variation of AArch64 breakpoint compared
to GDB. This causes problems when debugging Windows on ARM binaries, when
program breakpoints are being used.
The proposed patch creates a new gdbarch method (gdbarch_program_breakpoint_here_p)
that tells GDB whether the underlying instruction is a breakpoint instruction
or not.
This is more general than only checking for the instruction GDB uses as
breakpoint.
The existing logic is still preserved for targets that do not implement this
new gdbarch method.
The end result is like so:

gdb/ChangeLog:
Update copyright year range in all GDB files.

The documentation for make-breakpoint from the Guile API and the `spec'
variant of the gdb.Breakpoint constructor from the Python API state that
the format acceptable for location strings is the same as that accepted
by the break command. However, using the -probe qualifier at the
beginning of the location string causes a GDB internal error as it
attempts to decode a probe location in the wrong code path. Without this
functionality, there doesn't appear to be another way to set breakpoints
on probe points from Python or Guile scripts.
This patch introduces a new helper function that returns a
breakpoint_ops instance appropriate for a parsed location and updates
the Guile and Python bindings to use said function, rather than the
current hard-coded use of bkpt_breakpoint_ops. Since this logic is
duplicated in the handling of the `break' and `trace' commands, those
are also updated to call into the new helper function.

This commit makes "maint info breakpoints" show the internal locations
of C++ exception catchpoints:
(gdb) info breakpoints
Num Type Disp Enb Address What
2 catchpoint keep y exception catch
With multiple locations:
(gdb) maint info breakpoints
Num Type Disp Enb Address What
2 catchpoint keep y exception catch
2.1 y 0x000000000040545f <__cxa_begin_catch+95> inf 1
2.2 y 0x00007ffff71dbe0f <__cxxabiv1::__cxa_begin_catch(void*)+95> inf 1
(gdb)
With a single location:
(gdb) maint info breakpoints 2
Num Type Disp Enb Address What
2 catchpoint keep y exception catch inf 1
2.1 y 0x00007ffff7bc0b7f <__cxa_begin_catch+95> inf 1
With no locations:
(gdb) maint info breakpoints 2
Num Type Disp Enb Address What
2 catchpoint keep y exception catch inf 1
Other catchpoints still show the same way, here a catch signal:
(gdb) info breakpoints
Num Type Disp Enb Address What
3 catchpoint keep y signal "<standard signals>"
(gdb) maint info breakpoints
Num Type Disp Enb Address What
3 catchpoint keep y signal "<standard signals>" inf 1
(gdb)
Note: I considered making the locations be printed from within
breakpoint_ops::print_one(), but gave up given the handling for the
broken MI v2 output:
/* The mi2 broken format: the main breakpoint tuple ends here, the locations
are outside. */
if (!use_fixed_output)
bkpt_tuple_emitter.reset ();
in print_one_breakpoint.

Currently, with:
(gdb) catch catch
Catchpoint 1 (catch)
(gdb) catch throw
Catchpoint 2 (throw)
(gdb) catch rethrow
Catchpoint 3 (rethrow)
You get:
(gdb) info breakpoints
Num Type Disp Enb Address What
1 breakpoint keep y 0x0000000000b122af exception catch
2 breakpoint keep y 0x0000000000b1288d exception throw
3 breakpoint keep y 0x0000000000b12931 exception rethrow
I think it doesn't make much sense usability-wise, to show a
catchpoint as a breakpoint. The fact that GDB sets a breakpoint at
some magic address in the C++ run time is an implementation detail,
IMO. And as seen in the previous patch, such a catchpoint can end up
with more than one location/address even, so showing a single address
isn't entirely accurate.
This commit hides the addresses from view, and makes GDB show
"catchpoint" for type as well:
(gdb) info breakpoints
Num Type Disp Enb Address What
1 catchpoint keep y exception catch
2 catchpoint keep y exception throw
3 catchpoint keep y exception rethrow
This comment in the code seems telling:
/* We need to reset 'type' in order for code in breakpoint.c to do
the right thing. */
cp->type = bp_breakpoint;
It kind of suggests that the reason catchpoints end up shown as
breakpoints was that it was easier to implement them that way, rather
than a desired property.
This commit fixes things up to make it possible to have bp_catch
breakpoints have software/hardware breakpoint locations, thus
eliminating the need for that hack:
- redo breakpoint_address_is_meaningful in terms of the location's
type rather than breakpoint type.
- teach bpstat_what about stepping over the catchpoint locations.
- install a allocate_location method for "catch catch/throw/rethrow",
one that forces the location type.
Note that this also reverts the gdb hunk from:
commit 2a8be20359dba9cc684fd3ffa222d985399f3b18
Commit: Tom Tromey <tom@tromey.com>
CommitDate: Sat Oct 6 22:17:45 2018 -0600
Fix Python gdb.Breakpoint.location crash
because now "catch throw" catchpoints hit the
if (obj->bp->type != bp_breakpoint)
Py_RETURN_NONE;
check above, and, adjusts the testcase to no longer expect to see the
catchpoint in the gdb.breakpoints() list.
(Note: might make sense to do the same to Ada exception catchpoints.)

This is the next patch in the ongoing series to move gdbsever to the
top level.
This patch just renames the "common" directory. The idea is to do
this move in two parts: first rename the directory (this patch), then
move the directory to the top. This approach makes the patches a bit
more tractable.
I chose the name "gdbsupport" for the directory. However, as this
patch was largely written by sed, we could pick a new name without too
much difficulty.
Tested by the buildbot.

Adds some MI commands to catch C++ exceptions. The new commands are
-catch-throw, -catch-rethrow, and -catch-catch, these all correspond
to the CLI commands 'catch throw', 'catch rethrow', and 'catch catch'.
Each MI command takes two optional arguments, '-t' has the effect of
calling 'tcatch' instead of 'catch', for example:
(gdb)
-catch-throw -t
Is the same as:
(gdb) tcatch throw
There is also a '-r REGEXP' argument that can supply a regexp to match
against the exception type, so:
(gdb)
-catch-catch -r PATTERN
Is the same as:
(gdb) catch catch PATTERN
The change in print_mention_exception_catchpoint might seem a little
strange; changing the output from using ui_out::field_int and
ui_out::text to using ui_out::message.
The print_mention_exception_catchpoint is used as the 'print_mention'
method for the exception catchpoint breakpoint object. Most of the
other 'print_mention' methods (see breakpoint.c) use either
printf_filtered, of ui_out::message. Using field_int was causing an
unexpected field to be added to the MI output. Here's the output
without the change in print_mention_exception_catchpoint:
(gdb)
-catch-throw
^done,bkptno="1",bkpt={number="1",type="breakpoint",disp="keep",
enabled="y",addr="0x00000000004006c0",
what="exception throw",catch-type="throw",
thread-groups=["i1"],times="0"}
Notice the breakpoint number appears in both the 'bkptno' field, and
the 'number' field within the 'bkpt' tuple. Here's the output with
the change in print_mention_exception_catchpoint:
(gdb)
-catch-throw
^done,bkpt={number="1",type="breakpoint",disp="keep",
enabled="y",addr="0x00000000004006c0",
what="exception throw",catch-type="throw",
thread-groups=["i1"],times="0"}

Since commit
b4be1b064860 ("Fix MI output for multi-location breakpoints")
we get this error when building with --disable-gdbmi:
CXXLD gdb
/home/smarchi/src/binutils-gdb/gdb/breakpoint.c:6358: error: undefined reference to 'mi_multi_location_breakpoint_output_fixed(ui_out*)'
This is due to breakpoint.c using a function defined in mi/mi-main.c, even
though mi/mi-main.c isn't included in the build.
To fix it, use the flags feature of ui_out. mi_ui_out has the new
fix_multi_location_breakpoint_output flag set for versions >= 3. Also,
move the global variable fix_multi_location_breakpoint_output to
breakpoint.c, so it can be read there even when we build without MI. I
renamed it to fix_multi_location_breakpoint_output_globally so it
doesn't clash with the new enumerator.
gdb/ChangeLog:
* breakpoint.h (fix_multi_location_breakpoint_output_globally):
New variable declaration.
* breakpoint.c (fix_multi_location_breakpoint_output_globally):
New variable.
(print_one_breakpoint): Use ui_out::test_flags and new global
variable to compute use_fixed_output.
* mi/mi-main.h (mi_multi_location_breakpoint_output_fixed):
Remove.
* mi/mi-main.c (fix_multi_location_breakpoint_output): Remove.
(mi_multi_location_breakpoint_output_fixed): Remove.
(mi_cmd_fix_multi_location_breakpoint_output): Adjust to set the
new variable.
* mi/mi-out.c (mi_ui_out::mi_ui_out): Set
fix_multi_location_breakpoint_output flag if version >= 3.
* ui-out.h (enum ui_out_flag)
<fix_multi_location_breakpoint_output>: New enumerator.

Andreas Schwab and John Baldwin pointed out some bugs in the header
sorting patch; and I noticed that the output was not correct when
limited to a subset of files (a bug in my script).
So, I'm reverting the patch. I may try again after fixing the issues
pointed out.

Philippe noticed a memory leak coming from ada_catchpoint_location --

This patch fixes the problem by further C++-ifying bp_location. In
particular, bp_location_ops is now removed, and the "dtor" function
pointer is replaced with an ordinary destructor.

This commit applies all changes made after running the gdb/copyright.py
script.
Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.
gdb/ChangeLog:
Update copyright year range in all GDB files.
