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:

Multi-target support
This commit adds multi-target support to GDB. What this means is that
with this commit, GDB can now be connected to different targets at the
same time. E.g., you can debug a live native process and a core dump
at the same time, connect to multiple gdbservers, etc.
Actually, the word "target" is overloaded in gdb. We already have a
target stack, with pushes several target_ops instances on top of one
another. We also have "info target" already, which means something
completely different to what this patch does.
So from here on, I'll be using the "target connections" term, to mean
an open process_stratum target, pushed on a target stack. This patch
makes gdb have multiple target stacks, and multiple process_stratum
targets open simultaneously. The user-visible changes / commands will
also use this terminology, but of course it's all open to debate.
User-interface-wise, not that much changes. The main difference is
that each inferior may have its own target connection.
A target connection (e.g., a target extended-remote connection) may
support debugging multiple processes, just as before.
Say you're debugging against gdbserver in extended-remote mode, and
you do "add-inferior" to prepare to spawn a new process, like:
(gdb) target extended-remote :9999
...
(gdb) start
...
(gdb) add-inferior
Added inferior 2
(gdb) inferior 2
[Switching to inferior 2 [<null>] (<noexec>)]
(gdb) file a.out
...
(gdb) start
...
At this point, you have two inferiors connected to the same gdbserver.
With this commit, GDB will maintain a target stack per inferior,
instead of a global target stack.
To preserve the behavior above, by default, "add-inferior" makes the
new inferior inherit a copy of the target stack of the current
inferior. Same across a fork - the child inherits a copy of the
target stack of the parent. While the target stacks are copied, the
targets themselves are not. Instead, target_ops is made a
refcounted_object, which means that target_ops instances are
refcounted, which each inferior counting for a reference.
What if you want to create an inferior and connect it to some _other_
target? For that, this commit introduces a new "add-inferior
-no-connection" option that makes the new inferior not share the
current inferior's target. So you could do:
(gdb) target extended-remote :9999
Remote debugging using :9999
...
(gdb) add-inferior -no-connection
[New inferior 2]
Added inferior 2
(gdb) inferior 2
[Switching to inferior 2 [<null>] (<noexec>)]
(gdb) info inferiors
Num Description Executable
1 process 18401 target:/home/pedro/tmp/main
* 2 <null>
(gdb) tar extended-remote :10000
Remote debugging using :10000
...
(gdb) info inferiors
Num Description Executable
1 process 18401 target:/home/pedro/tmp/main
* 2 process 18450 target:/home/pedro/tmp/main
(gdb)
A following patch will extended "info inferiors" to include a column
indicating which connection an inferior is bound to, along with a
couple other UI tweaks.
Other than that, debugging is the same as before. Users interact with
inferiors and threads as before. The only difference is that
inferiors may be bound to processes running in different machines.
That's pretty much all there is to it in terms of noticeable UI
changes.
On to implementation.
Since we can be connected to different systems at the same time, a
ptid_t is no longer a unique identifier. Instead a thread can be
identified by a pair of ptid_t and 'process_stratum_target *', the
later being the instance of the process_stratum target that owns the
process/thread. Note that process_stratum_target inherits from
target_ops, and all process_stratum targets inherit from
process_stratum_target. In earlier patches, many places in gdb were
converted to refer to threads by thread_info pointer instead of
ptid_t, but there are still places in gdb where we start with a
pid/tid and need to find the corresponding inferior or thread_info
objects. So you'll see in the patch many places adding a
process_stratum_target parameter to functions that used to take only a
ptid_t.
Since each inferior has its own target stack now, we can always find
the process_stratum target for an inferior. That is done via a
inf->process_target() convenience method.
Since each inferior has its own target stack, we need to handle the
"beneath" calls when servicing target calls. The solution I settled
with is just to make sure to switch the current inferior to the
inferior you want before making a target call. Not relying on global
context is just not feasible in current GDB. Fortunately, there
aren't that many places that need to do that, because generally most
code that calls target methods already has the current context
pointing to the right inferior/thread. Note, to emphasize -- there's
no method to "switch to this target stack". Instead, you switch the
current inferior, and that implicitly switches the target stack.
In some spots, we need to iterate over all inferiors so that we reach
all target stacks.
Native targets are still singletons. There's always only a single
instance of such targets.
Remote targets however, we'll have one instance per remote connection.
The exec target is still a singleton. There's only one instance. I
did not see the point of instanciating more than one exec_target
object.
After vfork, we need to make sure to push the exec target on the new
inferior. See exec_on_vfork.
For type safety, functions that need a {target, ptid} pair to identify
a thread, take a process_stratum_target pointer for target parameter
instead of target_ops *. Some shared code in gdb/nat/ also need to
gain a target pointer parameter. This poses an issue, since gdbserver
doesn't have process_stratum_target, only target_ops. To fix this,
this commit renames gdbserver's target_ops to process_stratum_target.
I think this makes sense. There's no concept of target stack in
gdbserver, and gdbserver's target_ops really implements a
process_stratum-like target.
The thread and inferior iterator functions also gain
process_stratum_target parameters. These are used to be able to
iterate over threads and inferiors of a given target. Following usual
conventions, if the target pointer is null, then we iterate over
threads and inferiors of all targets.
I tried converting "add-inferior" to the gdb::option framework, as a
preparatory patch, but that stumbled on the fact that gdb::option does
not support file options yet, for "add-inferior -exec". I have a WIP
patchset that adds that, but it's not a trivial patch, mainly due to
need to integrate readline's filename completion, so I deferred that
to some other time.
In infrun.c/infcmd.c, the main change is that we need to poll events
out of all targets. See do_target_wait. Right after collecting an
event, we switch the current inferior to an inferior bound to the
target that reported the event, so that target methods can be used
while handling the event. This makes most of the code transparent to
multi-targets. See fetch_inferior_event.
infrun.c:stop_all_threads is interesting -- in this function we need
to stop all threads of all targets. What the function does is send an
asynchronous stop request to all threads, and then synchronously waits
for events, with target_wait, rinse repeat, until all it finds are
stopped threads. Now that we have multiple targets, it's not
efficient to synchronously block in target_wait waiting for events out
of one target. Instead, we implement a mini event loop, with
interruptible_select, select'ing on one file descriptor per target.
For this to work, we need to be able to ask the target for a waitable
file descriptor. Such file descriptors already exist, they are the
descriptors registered in the main event loop with add_file_handler,
inside the target_async implementations. This commit adds a new
target_async_wait_fd target method that just returns the file
descriptor in question. See wait_one / stop_all_threads in infrun.c.
The 'threads_executing' global is made a per-target variable. Since
it is only relevant to process_stratum_target targets, this is where
it is put, instead of in target_ops.
You'll notice that remote.c includes some FIXME notes. These refer to
the fact that the global arrays that hold data for the remote packets
supported are still globals. For example, if we connect to two
different servers/stubs, then each might support different remote
protocol features. They might even be different architectures, like
e.g., one ARM baremetal stub, and a x86 gdbserver, to debug a
host/controller scenario as a single program. That isn't going to
work correctly today, because of said globals. I'm leaving fixing
that for another pass, since it does not appear to be trivial, and I'd
rather land the base work first. It's already useful to be able to
debug multiple instances of the same server (e.g., a distributed
cluster, where you have full control over the servers installed), so I
think as is it's already reasonable incremental progress.
Current limitations:
- You can only resume more that one target at the same time if all
targets support asynchronous debugging, and support non-stop mode.
It should be possible to support mixed all-stop + non-stop
backends, but that is left for another time. This means that
currently in order to do multi-target with gdbserver you need to
issue "maint set target-non-stop on". I would like to make that
mode be the default, but we're not there yet. Note that I'm
talking about how the target backend works, only. User-visible
all-stop mode works just fine.
- As explained above, connecting to different remote servers at the
same time is likely to produce bad results if they don't support the
exact set of RSP features.

Fix scripted probe breakpoints
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. gdb/ChangeLog: 2019-12-10 George Barrett <bob@bob131.so> Fix scripted probe breakpoints. * breakpoint.c (tracepoint_probe_breakpoint_ops): Move declaration forward. (breakpoint_ops_for_event_location_type) (breakpoint_ops_for_event_location): Add function definitions.

gdb: small cleanup in breakpoint.c's includes
In an attempt to reduce the number of files re-build when some headers are touched, I ran include-what-you-use with breakpoint.c as a guinea pig. It revealed a few files that were unnecessary to include, which this patch removes. breakpoint.c uses tilde_expand from readline, hence the necessity to include tilde.h. AFAIK, it's fine to include just that, and not the whole readline headers. include-what-you-use also reported many header files that should be included but aren't, I suppose that breakpoint.c currently includes them indirectly. For now I'll pretend I didn't see that :). gdb/ChangeLog: * breakpoint.c: Remove some includes: continuations.h, skip.h, mi/mi-main.h, readline/readline.h, readline/history.h. Add include: readline/tilde.h. -#include "skip.h" #include "ax-gdb.h" #include "dummy-frame.h" #include "interps.h" @@ -69,11 +67,9 @@ #include "thread-fsm.h" #include "tid-parse.h" #include "cli/cli-style.h" -#include "mi/mi-main.h" /* readline include files */ -#include "readline/readline.h" -#include "readline/history.h" +#include "readline/tilde.h" /* readline defines this. */ #undef savestring Change-Id: I88bfe9071f2f973fd84caaf04b95c33a4dfb33de |

Introduce metadata style
This introduces a new "metadata" style and changes many places in gdb to use it. The idea here is to let the user distinguish gdb output from output that (conceptually at least) comes directly from the inferior. The newly-styled category includes text that gdb traditionally surrounds in "<...>", like "<unavailable>". I only added a single test for this. In many cases this output is difficult to test. Also, while developing this errors in the implementation of the new printf formats showed up as regressions. gdb/ChangeLog 2019-10-01 Tom Tromey <tom@tromey.com> * p-lang.c (pascal_printstr): Use metadata style. * value.c (show_convenience): Use metadata style. * valprint.c (valprint_check_validity, val_print_optimized_out) (val_print_not_saved, val_print_unavailable) (val_print_invalid_address, generic_val_print, val_print) (value_check_printable, val_print_array_elements): Use metadata style. * ui-out.h (class ui_out) <field_fmt>: New overload. <do_field_fmt>: Add style parameter. * ui-out.c (ui_out::field_fmt): New overload. * typeprint.c (type_print_unknown_return_type) (val_print_not_allocated, val_print_not_associated): Use metadata style. * tui/tui-out.h (class tui_ui_out) <do_field_fmt>: Add style parameter. * tui/tui-out.c (tui_ui_out::do_field_fmt): Update. * tracepoint.c (tvariables_info_1): Use metadata style. * stack.c (print_frame_arg, print_frame_info, print_frame) (info_frame_command_core): Use metadata style. * skip.c (info_skip_command): Use metadata style. * rust-lang.c (rust_print_enum): Use metadata style. * python/py-prettyprint.c (print_stack_unless_memory_error): Use metadata style. * python/py-framefilter.c (py_print_single_arg): Use metadata style. * printcmd.c (do_one_display, print_variable_and_value): Use metadata style. * p-valprint.c (pascal_val_print) (pascal_object_print_value_fields): Use metadata style. * p-typeprint.c (pascal_type_print_base): Use metadata style. * mi/mi-out.h (class mi_ui_out) <do_field_fmt>: Add style parameter. * mi/mi-out.c (mi_ui_out::do_field_fmt): Update. * m2-valprint.c (m2_print_long_set): Use metadata style. * m2-typeprint.c (m2_print_type): Use metadata style. * infcmd.c (print_return_value_1): Use metadata style. * gnu-v3-abi.c (print_one_vtable): Use metadata style. * f-valprint.c (info_common_command_for_block): Use metadata style. * f-typeprint.c (f_type_print_base): Use metadata style. * expprint.c (print_subexp_standard): Use metadata style. * cp-valprint.c (cp_print_value_fields): Use metadata style. * cli/cli-style.h (class cli_style_option): Add constructor.

Make first and last lines of 'command help documentation' consistent.
With this patch, the help docs now respect 2 invariants: * The first line of a command help is terminated by a '.' character. * The last character of a command help is not a newline character. Note that the changes for the last invariant were done by Tom, as part of : [PATCH] Remove trailing newlines from help text https://sourceware.org/ml/gdb-patches/2019-06/msg00050.html but some occurrences have been re-introduced since then. Some help docs had to be rephrased/restructured to respect the above invariants. Before this patch, print_doc_line was printing the first line of a command help documentation, but stopping at the first '.' or ',' character. This was giving inconsistent results : * The first line of command helps was sometimes '.' terminated, sometimes not. * The first line of command helps was not always designed to be readable/understandable/unambiguous when stopping at the first '.' or ',' character. This e.g. created the following inconsistencies/problems: < catch exception -- Catch Ada exceptions < catch handlers -- Catch Ada exceptions < catch syscall -- Catch system calls by their names < down-silently -- Same as the `down' command while the new help is: > catch exception -- Catch Ada exceptions, when raised. > catch handlers -- Catch Ada exceptions, when handled. > catch syscall -- Catch system calls by their names, groups and/or numbers. > down-silently -- Same as the `down' command, but does not print anything. Also, the command help doc should not be terminated by a newline character, but this was not respected by all commands. The cli-option -OPT framework re-introduced some occurences. So, the -OPT build help framework was changed to not output newlines at the end of %OPTIONS% replacement. This patch changes the help documentations to ensure the 2 invariants given above. It implied to slightly rephrase or restructure some help docs. Based on the above invariants, print_doc_line (called by 'apropos' and 'help' commands to print the first line of a command help) now outputs the full first line of a command help. This all results in a lot of small changes in the produced help docs. There are less code changes than changes in the help docs, as a lot of docs are produced by some code (e.g. the remote packet usage settings). gdb/ChangeLog 2019-08-07 Philippe Waroquiers <philippe.waroquiers@skynet.be> * cli/cli-decode.h (print_doc_line): Add for_value_prefix argument. * cli/cli-decode.c (print_doc_line): Likewise.

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.

"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:

Fix "info break" + "catch catch" + -static-{libstdc++,libgcc}
If you debug current GDB, set a "catch catch/throw/rethrow"
catchpoint, and then do "info breakpoints", the top GDB hits an
internal error:
(top-gdb) catch catch
Catchpoint 1 (catch)
(top-gdb) info breakpoints
Num Type Disp Enb Address What
1 breakpoint keep y src/gdb/breakpoint.c:6040: internal-error: void print_one_breakpoint_location(breakpoint*, bp_location*, int, bp_location**, int): Assertion `b->loc == NULL || b->loc->next == NULL' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
The assertion in question is asserting that a breakpoint with a
print_one method only has one location, and it fails because this
catchpoint ends up with two locations.
Internally, "catch catch" sets a breakpoint at __cxa_begin_catch. If
we do that manually, we see the locations:
(top-gdb) b -qualified __cxa_begin_catch
Breakpoint 2 at 0xb122b0 (2 locations)
(top-gdb) info breakpoints
Num Type Disp Enb Address What
2 breakpoint keep y <MULTIPLE>
2.1 y 0x0000000000b122b0 <__cxa_begin_catch>
2.2 y 0x00007ffff2f4ddb0 in __cxxabiv1::__cxa_begin_catch(void*) at ../../../../libstdc++-v3/libsupc++/eh_catch.cc:41
Note that I had used -qualified. It seems strange that we get a
location for a namespaced symbol, but that happens because the minimal
symbol for that address is indeed called __cxa_begin_catch.
The real issue is that gdb is linked with
-static-libgcc/-static-libstdc++. And then, it _also_ ends up with
shared libstc++ loaded:
(top-gdb) info sharedlibrary stdc++
From To Syms Read Shared Object Library
0x00007ffff2f4b380 0x00007ffff2ffc018 Yes /lib64/libstdc++.so.6
Location 2.2 is set within libstdc++.so.6's range:
(top-gdb) p 0x00007ffff2f4b380 <= 0x00007ffff2f4ddb0 && 0x00007ffff2f4ddb0 < 0x00007ffff2ffc018
$1 = true
So due to -static-lib*, we end up with _two_ copies of the
__cxa_begin_catch code:
(top-gdb) disassemble 0x0000000000b122b0
Dump of assembler code for function __cxa_begin_catch:
0x0000000000b122b0 <+0>: push %rbx
0x0000000000b122b1 <+1>: mov %rdi,%rbx
0x0000000000b122b4 <+4>: callq 0xb11a80 <__cxa_get_globals>
0x0000000000b122b9 <+9>: movabs $0xb8b1aabcbcd4d500,%rdx
...
(top-gdb) disassemble 0x00007ffff2f4ddb0
Dump of assembler code for function __cxxabiv1::__cxa_begin_catch(void*):
0x00007ffff2f4ddb0 <+0>: push %rbx
0x00007ffff2f4ddb1 <+1>: mov %rdi,%rbx
0x00007ffff2f4ddb4 <+4>: callq 0x7ffff2f4a090 <__cxa_get_globals@plt>
0x00007ffff2f4ddb9 <+9>: movabs $0xb8b1aabcbcd4d500,%rdx
...
I think we end up with libstdc++.so.6 loaded because
libsource-highlight.so depends on it.
Irrespective of whether it's a good idea to use
-static-libgcc/-static-libstdc++, GDB should not crash. Since there
are two copies of the code, it seems right to have more than one
location. So the fix is just to remove the assertion.
A testcase is included, which mimics the scenerio described above,
with binary linked with -static-lib{stdc++,gcc} and a shared library
that is linked normally, along with other combinations for good
measure.

Rename common to gdbsupport
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.

gdb: Remove unneeded parameter from set_breakpoint_location_function
The explicit_loc parameter in set_breakpoint_location_function is not useful. This parameter is set from two possible fields of the symtab_and_line used to create the breakpoint; the explicit_pc field, and the explicit_line field. First, the explicit_line field, this is not currently set for any breakpoint command, so will never be true. Next, the explicit_pc field. This can be true but will never be true at the same time that the sal->msymbol field is also true - the sal->msymbol is only ever set in linespec.c:minsym_found, which doesn't allow for explicitly setting the pc. The result of this is that if we are setting a breakpoint on an msymbol that could turn out to be an ifunc, then we will not also have either an explicit_pc or an explicit_line, this check can therefore be removed. There should be no user visible changes after this commit. gdb/ChangeLog: * breakpoint.c (set_breakpoint_location_function): Remove explicit_loc parameter. (momentary_breakpoint_from_master): Update call to set_breakpoint_location_function. (add_location_to_breakpoint): Likewise. |

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"}

Remove trailing newlines from help text
I noticed recently that some command had a trailing newline in its "help" output. So, I temporarily hacked cli-decode.c to print something when a new command was installed that had a trailing newline in its help message, and wrote this patch, which removes all the ones I could find this way.

Introduce and use make_unique_xstrdup
Adds an utility function to make it shorter to write the common case of wrapping an xstrdup with a unique_xmalloc_ptr, and uses it throughout. Note: I tried to put this in common/common-utils.h near skip_spaces, etc. but that is included in common/common-defs.h before common/gdb_unique_ptr.h is included, so it would fail to compile because gdb::unique_xmalloc_ptr isn't defined at that point yet. I tried moving the gdb_unique_ptr.h inclusion before common-utils.h, but that doesn't work because gdb_unique_ptr.h depends on common-utils.h for xfree. gdb/ChangeLog: 2019-06-04 Pedro Alves <palves@redhat.com> * common/gdb_unique_ptr.h (make_unique_xstrdup): New. * ada-lang.c (catch_ada_completer): Use make_unique_xstrdup. * breakpoint.c (condition_completer): Likewise. * cli/cli-dump.c (scan_expression): Likewise. * common/filestuff.c (mkdir_recursive): Likewise. * common/gdb_tilde_expand.c (gdb_tilde_expand_up) * common/pathstuff.c (gdb_realpath, gdb_realpath_keepfile) (gdb_abspath): Likewise. * compile/compile-cplus-types.c (compile_cplus_instance::decl_name): Likewise. * completer.c (complete_explicit_location): (signal_completer, reg_or_group_completer_1): Likewise. * cp-support.c (cp_remove_params_if_any): Likewise. * fbsd-tdep.c (fbsd_core_vnode_path): Likewise. * guile/scm-safe-call.c (gdbscm_safe_eval_string): Likewise. * infcmd.c (strip_bg_char): Likewise. * linespec.c (copy_token_string): Likewise. * mi/mi-main.c (output_cores): Likewise. * psymtab.c (psymtab_search_name): * symfile.c (test_set_ext_lang_command): Likewise. * target.c (target_fileio_read_stralloc): Likewise. * tui/tui-regs.c (tui_reggroup_completer): Likewise. * value.c (complete_internalvar): Likewise. gdb/gdbserver/ChangeLog: 2019-06-04 Pedro Alves <palves@redhat.com> * server.c (captured_main): Use make_unique_xstrdup. |

Make exception handling more efficient

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.

Make exceptions use std::string and be self-managing
This changes the exception's "message" member to be a shared_ptr wrapping a std::string. This allows removing the stack of exception messages, because now exceptions will self-destruct when needed.

Move innermost_block_tracker global to parse_state

Have parser reset the innermost block tracker
I ran across a comment in symfile.c today:
/* Clear globals which might have pointed into a removed objfile.
FIXME: It's not clear which of these are supposed to persist
between expressions and which ought to be reset each time. */
It seems to me that this can be clarified: the parser entry points
ought to reset the innermost block tracker (and the expression context
block), and these should not be considered valid for code to use at
arbitrary times -- only immediately after an expression has been
parsed.
This patch implements this idea. This could be further improved by
removing the parser globals and changing the parser functions to
return this information, but I have not done this.
Tested by the buildbot.

Fix MI output for multi-location breakpoints
New in v2:
- Addressed comments about doc, updated the MI version table
- New doc for the Breakpoint information format
- New -fix-multi-location-breakpoint-output command, with associated
doc, test and NEWS updated accordingly
- Fixed the output, the locations list is now actually in the tuple
representing the breakpoint.
Various MI commands or events related to breakpoints output invalid MI
records when printing information about a multi-location breakpoint.
For example:
-break-insert allo
^done,bkpt={...,addr="<MULTIPLE>",...},{number="1.1",...},{number="1.2",...}
The problem is that according to the syntax [1], the top-level elements
are of type "result" and should be of the form "variable=value".
This patch changes the output to wrap the locations in a list:
^done,bkpt={...,addr="<MULTIPLE>",locations=[{number="1.1",...},{number="1.2",...}]}
The events =breakpoint-created, =breakpoint-modified, as well as the
-break-info command also suffer from this (and maybe others I didn't
find).
Since this is a breaking change for MI, we have to deal somehow with
backwards compatibility. The approach taken by this patch is to bump
the MI version, use the new syntax in MI3 while retaining the old syntax
in MI2. Frontends are expected to use a precise MI version (-i=mi2), so
if they do that they should be unaffected.
The patch also adds the command -fix-multi-location-breakpoint-output,
which front ends can use to enable this behavior with MI <= 2.
[1] https://sourceware.org/gdb/onlinedocs/gdb/GDB_002fMI-Output-Syntax.html#GDB_002fMI-Output-Syntax
gdb/ChangeLog:
* NEWS: Mention that the new default MI version is 3. Mention
changes to the output of commands and events that deal with
multi-location breakpoints.
* breakpoint.c: Include "mi/mi-out.h".
(print_one_breakpoint): Change output syntax if using MI version
>= 3.
* mi/mi-main.h (mi_cmd_fix_multi_location_breakpoint_output):
New.
(mi_multi_location_breakpoint_output_fixed): New.
* mi/mi-main.c (fix_multi_location_breakpoint_output): New.

* mi/mi-cmds.c (mi_cmds): Register command
-fix-multi-location-breakpoint-output.
* mi/mi-out.c (mi_out_new): Instantiate version 3 when using
interpreter "mi".
gdb/testsuite/ChangeLog:
* mi-breakpoint-location-ena-dis.exp: Rename to ...
* mi-breakpoint-multiple-locations.exp: ... this.
(make_breakpoints_pattern): New proc.
(do_test): Add mi_version parameter, test -break-insert,
-break-info and =breakpoint-created.
gdb/doc/ChangeLog:
* gdb.texinfo (Mode Options): Mention mi3.
(Interpreters): Likewise.
(GDB/MI Development and Front Ends): Add entry for MI 3 in
version table. Document -fix-multi-location-breakpoint-output.

C++-ify bp_location
Philippe noticed a memory leak coming from ada_catchpoint_location -- it was not freeing the "function_name" member from its base class: ==14141== 114 bytes in 4 blocks are definitely lost in loss record 1,055 of 3,424 ==14141== at 0x4C2BE6D: malloc (vg_replace_malloc.c:309) ==14141== by 0x405107: xmalloc (common-utils.c:44) ==14141== by 0x7563F9: xstrdup (xstrdup.c:34) ==14141== by 0x3B82B3: set_breakpoint_location_function(bp_location*, int) (breakpoint.c:7156) ==14141== by 0x3C112B: add_location_to_breakpoint(breakpoint*, symtab_and_line const*) (breakpoint.c:8609) ==14141== by 0x3C127A: init_raw_breakpoint(breakpoint*, gdbarch*, symtab_and_line, bptype, breakpoint_ops const*) (breakpoint.c:7187) ==14141== by 0x3C1B52: init_ada_exception_breakpoint(breakpoint*, gdbarch*, symtab_and_line, char const*, breakpoint_ops const*, int, int, int) (breakpoint.c:11262) ==14141== by 0x381C2E: create_ada_exception_catchpoint(gdbarch*, ada_exception_catchpoint_kind, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, int, int, int) (ada-lang.c:13255) This patch fixes the problem by further C++-ifying bp_location.
