gdb: only insert thread-specific breakpoints in the relevant inferior
This commit updates GDB so that thread or inferior specific breakpoints are only inserted into the program space in which the specific thread or inferior is running. In terms of implementation, getting this basically working is easy enough, now that a breakpoint's thread or inferior field is setup prior to GDB looking for locations, we can easily use this information to find a suitable program_space and pass this to as a filter when creating the sals. Or we could if breakpoint_ops::create_sals_from_location_spec allowed us to pass in a filter program_space. So, this commit extends breakpoint_ops::create_sals_from_location_spec to take a program_space argument, and uses this to filter the set of returned sals. This accounts for about half the change in this patch. The second set of changes starts from breakpoint_set_thread and breakpoint_set_inferior, this is called when the thread or inferior for a breakpoint changes, e.g. from the Python API. Previously this call would never result in the locations of a breakpoint changing, after all, locations were inserted in every program space, and we just use the thread or inferior variable to decide when we should stop. Now though, changing a breakpoint's thread or inferior can mean we need to figure out a new set of breakpoint locations. To support this I've added a new breakpoint_re_set_one function, which is like breakpoint_re_set, but takes a single breakpoint, and just updates the locations for that one breakpoint. We only need to call this function if the program_space in which a breakpoint's thread (or inferior) is running actually changes. If the program_space does change then we call the new breakpoint_re_set_one function passing in the program_space which should be used to filter the new locations (or nullptr to indicate we should set locations in all program spaces). This filter program_space needs to propagate down to all the re_set methods, this accounts for the remaining half of the changes in this patch. There were a couple of existing tests that created thread or inferior specific breakpoints and then checked the 'info breakpoints' output, these needed updating. These were: gdb.mi/user-selected-context-sync.exp gdb.multi/bp-thread-specific.exp gdb.multi/multi-target-continue.exp gdb.multi/multi-target-ping-pong-next.exp gdb.multi/tids.exp gdb.mi/new-ui-bp-deleted.exp gdb.multi/inferior-specific-bp.exp gdb.multi/pending-bp-del-inferior.exp I've also added some additional tests to: gdb.multi/pending-bp.exp I've updated the documentation and added a NEWS entry.

gdb: remove gdbcmd.h
Most files including gdbcmd.h currently rely on it to access things actually declared in cli/cli-cmds.h (setlist, showlist, etc). To make things easy, replace all includes of gdbcmd.h with includes of cli/cli-cmds.h. This might lead to some unused includes of cli/cli-cmds.h, but it's harmless, and much faster than going through the 170 or so files by hand.

Update copyright year range in header of all files managed by GDB
This commit is the result of the following actions:
- Running gdb/copyright.py to update all of the copyright headers to
include 2024,
- Manually updating a few files the copyright.py script told me to
update, these files had copyright headers embedded within the
file,
- Regenerating gdbsupport/Makefile.in to refresh it's copyright
date,
- Using grep to find other files that still mentioned 2023. If
these files were updated last year from 2022 to 2023 then I've
updated them this year to 2024.
I'm sure I've probably missed some dates. Feel free to fix them up as
you spot them.

gdb: constify breakpoint::print_it parameter
The print_it method itself is const. In a subsequent patch, the locations that come out of a const breakpoint will be const as well. It will therefore be needed to make the last_loc output parameter const as well. Make that change now to reduce the size of the following patches.

gdb: make some breakpoint methods use this
Some implementations of breakpoint::check_status and
breakpoint::print_it do this:
struct breakpoint *b = bs->breakpoint_at;
bs->breakpoint_at is always the same as `this` (we can get convinced by
looking at the call sites of check_status and print_it), so it would
just be clearer to access fields through `this` instead.

Show locno for 'multi location' breakpoint hit msg+conv var $_hit_bbnum $_hit_locno PR breakpoints/12464
This implements the request given in PR breakpoints/12464.
Before this patch, when a breakpoint that has multiple locations is reached,
GDB printed:
Thread 1 "zeoes" hit Breakpoint 1, some_func () at somefunc1.c:5
This patch changes the message so that bkpt_print_id prints the precise
encountered breakpoint:
Thread 1 "zeoes" hit Breakpoint 1.2, some_func () at somefunc1.c:5
In mi mode, bkpt_print_id also (optionally) prints a new table field "locno":
locno is printed when the breakpoint hit has more than one location.
Note that according to the GDB user manual node 'GDB/MI Development and Front
Ends', it is ok to add new fields without changing the MI version.
Also, when a breakpoint is reached, the convenience variables
$_hit_bpnum and $_hit_locno are set to the encountered breakpoint number
and location number.
$_hit_bpnum and $_hit_locno can a.o. be used in the command list of a
breakpoint, to disable the specific encountered breakpoint, e.g.
disable $_hit_bpnum.$_hit_locno
In case the breakpoint has only one location, $_hit_locno is set to
the value 1, so as to allow a command such as:
disable $_hit_bpnum.$_hit_locno
to disable the breakpoint even when the breakpoint has only one location.
This also fixes a strange behaviour: when a breakpoint X has only
one location,
enable|disable X.1
is accepted but transforms the breakpoint in a multiple locations
breakpoint having only one location.
The changes in RFA v4 handle the comments of Tom Tromey:
- Changed convenience var names from $bkptno/$locno to
$_hit_bpnum/$_hit_locno.
- updated the tests and user manual accordingly.
User manual also explictly describes that $_hit_locno is set to 1
for a breakpoint with a single location.
- The variable values are now set in bpstat_do_actions_1 so that
they are set for silent breakpoints, and when several breakpoints
are hit at the same time, that the variables are set to the printed
breakpoint.
The changes in RFA v3 handle the additional comments of Eli:
GDB/NEW:
- Use max 80-column
- Use 'code location' instead of 'location'.
- Fix typo $bkpno
- Ensure that disable $bkptno and disable $bkptno.$locno have
each their explanation inthe example
- Reworded the 'breakpoint-hit' paragraph.
gdb.texinfo:
- Use 'code location' instead of 'location'.
- Add a note to clarify the distinction between $bkptno and $bpnum.
- Use @kbd instead of examples with only one command.
Compared to RFA v1, the changes in v2 handle the comments given by
Keith Seitz and Eli Zaretskii:
- Use %s for the result of paddress
- Use bkptno_numopt_re instead of 2 different -re cases
- use C@t{++}
- Add index entries for $bkptno and $locno
- Added an example for "locno" in the mi interface
- Added examples in the Break command manual.

Change GDB to use frame_info_ptr
This changes GDB to use frame_info_ptr instead of frame_info *
The substitution was done with multiple sequential `sed` commands:
sed 's/^struct frame_info;/class frame_info_ptr;/'
sed 's/struct frame_info \*/frame_info_ptr /g' - which left some
issues in a few files, that were manually fixed.
sed 's/\<frame_info \*/frame_info_ptr /g'
sed 's/frame_info_ptr $/frame_info_ptr/g' - used to remove whitespace
problems.
The changed files were then manually checked and some 'sed' changes
undone, some constructors and some gets were added, according to what

Eliminate the two-level data structures behind location_specs
Currently, there's the location_spec hierarchy, and then some
location_spec subclasses have their own struct type holding all their
data fields.
I.e., there is this:
location_spec
explicit_location_spec
linespec_location_spec
address_location_spec
probe_location_spec
and then these separate types:
explicit_location
linespec_location
where:
explicit_location_spec
has-a explicit_location
linespec_location_spec
has-a linespec_location
This patch eliminates explicit_location and linespec_location,
inlining their members in the corresponding location_spec type.
The location_spec subclasses were the ones currently defined in
location.c, so they are moved to the header. Since the definitions of
the classes are now visible, we no longer need location_spec_deleter.
Some constructors that are used for cloning location_specs, like:
explicit explicit_location_spec (const struct explicit_location *loc)
... were converted to proper copy ctors.
In the process, initialize_explicit_location is eliminated, and some
functions that returned the "data type behind a locspec", like
get_linespec_location are converted to downcast functions, like
as_linespec_location_spec.

event_location -> location_spec
Currently, GDB internally uses the term "location" for both the
location specification the user input (linespec, explicit location, or
an address location), and for actual resolved locations, like the
breakpoint locations, or the result of decoding a location spec to
SaLs. This is expecially confusing in the breakpoints module, as
struct breakpoint has these two fields:
breakpoint::location;
breakpoint::loc;
"location" is the location spec, and "loc" is the resolved locations.
And then, we have a method called "locations()", which returns the
resolved locations as range...
The location spec type is presently called event_location:
/* Location we used to set the breakpoint. */
event_location_up location;
and it is described like this:
/* The base class for all an event locations used to set a stop event
in the inferior. */
struct event_location
{
and even that is incorrect... Location specs are used for finding
actual locations in the program in scenarios that have nothing to do
with stop events. E.g., "list" works with location specs.
To clean all this confusion up, this patch renames "event_location" to
"location_spec" throughout, and then all the variables that hold a
location spec, they are renamed to include "spec" in their name, like
e.g., "location" -> "locspec". Similarly, functions that work with
location specs, and currently have just "location" in their name are
renamed to include "spec" in their name too.

Rename base_breakpoint -> code_breakpoint
Even after the previous patches reworking the inheritance of several
breakpoint types, the present breakpoint hierarchy looks a bit
surprising, as we have "breakpoint" as the superclass, and then
"base_breakpoint" inherits from "breakpoint". Like so, simplified:
breakpoint
base_breakpoint
ordinary_breakpoint
internal_breakpoint
momentary_breakpoint
ada_catchpoint
exception_catchpoint
tracepoint
watchpoint
catchpoint
exec_catchpoint
...
The surprising part to me is having "base_breakpoint" being a subclass
of "breakpoint". I'm just refering to naming here -- I mean, you'd
expect that it would be the top level baseclass that would be called
"base".
Just flipping the names of breakpoint and base_breakpoint around
wouldn't be super great for us, IMO, given we think of every type of
*point as a breakpoint at the user visible level. E.g., "info
breakpoints" shows watchpoints, tracepoints, etc. So it makes to call
the top level class breakpoint.
Instead, I propose renaming base_breakpoint to code_breakpoint. The
previous patches made sure that all code breakpoints inherit from
base_breakpoint, so it's fitting. Also, "code breakpoint" contrasts
nicely with a watchpoint also being typically known as a "data
breakpoint".
After this commit, the resulting hierarchy looks like:
breakpoint
code_breakpoint
ordinary_breakpoint
internal_breakpoint
momentary_breakpoint
ada_catchpoint
exception_catchpoint
tracepoint
watchpoint
catchpoint
exec_catchpoint
...
... which makes a lot more sense to me.
I've left this patch as last in the series in case people want to
bikeshed on the naming.
"code" has a nice property that it's exactly as many letters as
"base", so this patch didn't require any reindentation. :-)

Introduce catchpoint class
This introduces a catchpoint class that is used as the base class for all catchpoints. init_catchpoint is rewritten to be a constructor instead.

gdb, gdbserver, gdbsupport: fix leading space vs tabs issues
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). gdb/ChangeLog: * aarch64-linux-tdep.c: Fix

Speed up psymbol reading by removing a copy
I noticed that cp_canonicalize_string and friends copy a unique_xmalloc_ptr to a std::string. However, this copy isn't genuinely needed anywhere, and it serves to slow down DWARF psymbol reading. This patch removes the copy and updates the callers to adapt. This speeds up the reader from 1.906 seconds (mean of 10 runs, of gdb on a copy of itself) to 1.888 seconds (mean of 10 runs, on the same copy as the first trial). gdb/ChangeLog 2020-05-08 Tom Tromey <tom@tromey.com> * symtab.h (class demangle_result_storage) <set_malloc_ptr>: New overload. <swap_string, m_string>: Remove. * symtab.c (demangle_for_lookup, completion_list_add_symbol): Update. * stabsread.c (define_symbol, read_type): Update. * linespec.c (find_linespec_symbols): Update. * gnu-v3-abi.c (gnuv3_get_typeid): Update. * dwarf2/read.c (dwarf2_canonicalize_name): Update. * dbxread.c (read_dbx_symtab): Update. * cp-support.h (cp_canonicalize_string_full) (cp_canonicalize_string, cp_canonicalize_string_no_typedefs): Return unique_xmalloc_ptr. * cp-support.c (inspect_type): Update.

gdb: add back declarations for _initialize functions
I'd like to enable the -Wmissing-declarations warning. However, it
warns for every _initialize function, for example:
CXX dcache.o
/home/smarchi/src/binutils-gdb/gdb/dcache.c: In function ‘void _initialize_dcache()’:
/home/smarchi/src/binutils-gdb/gdb/dcache.c:688:1: error: no previous declaration for ‘void _initialize_dcache()’ [-Werror=missing-declarations]
_initialize_dcache (void)
^~~~~~~~~~~~~~~~~~
The only practical way forward I found is to add back the declarations,
which were removed by this commit:

[gdb, c++] Improve error message when using libstdcxx without SDT probes
When using catch catch/rethrow/catch, a libstdcxx with SDT probes is required for both the regexp argument, and the convenience variable $_exception ( https://sourceware.org/gdb/current/onlinedocs/gdb/Set-Catchpoints.html ). Currently, when using these features with a libstdcxx without SDT probes, we get the cryptic error message: ... not stopped at a C++ exception catchpoint ... Improve this by instead emitting the more helpful: ... did not find exception probe (does libstdcxx have SDT probes?) ...

Make "maint info breakpoints" show "catch catch/throw/rethrow" locations
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.
gdb/ChangeLog:
2019-07-09 Pedro Alves <palves@redhat.com>
* break-catch-throw.c (is_exception_catchpoint): New.
* breakpoint.c (print_one_breakpoint_location): New parameter
'raw_loc'. Handle it. Use
is_watchpoint/is_catchpoint/is_exception_catchpoint instead of
looking at the breakpoint's type.
(print_one_breakpoint): If handling "maint info breakpoints", also
print locations of exception catchpoints.
* breakpoint.h (is_exception_catchpoint): Declare.

"catch catch/throw/rethrow", breakpoint -> catchpoint
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:

gdb/mi: New commands to catch C++ exceptions
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"}

Replace throw_exception with throw in some cases
This replaces throw_exception with "throw;" when possible. This was
written by script. The rule that is followed is that uses of the
form:
catch (... &name)
{
...
throw_exception (name);
}
... can be rewritten. This should always be safe, because exceptions
are caught by const reference, and therefore can't be modified in the
body of the catch.
