gdb: remove breakpoint_find_if
Remove breakpoint_find_if, replace its sole usage with using all_breakpoints directly instead. At the same time, change return types to use bool. Change-Id: I9ec392236b4804b362d16ab563330b9c07311106 |

gdb: remove cmd_list_element::function::sfunc
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. Change-Id: I1eb96326c9b511c293c76996cea0ebc51c70fac0 |

gdb: introduce iterator_range, remove next_adapter
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. gdbsupport/ChangeLog: * next-iterator.h (class next_adapter): Remove. * iterator-range.h: New. gdb/ChangeLog: * breakpoint.h (bp_locations_range): Remove.

gdb: remove iterate_over_breakpoints function
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. gdb/ChangeLog: * breakpoint.h (iterate_over_breakpoints): Remove. Update callers to use all_breakpoints or all_breakpoints_safe. (breakpoint_range, all_breakpoints, breakpoint_safe_range, all_breakpoints_safe): Move here. * breakpoint.c (all_breakpoints, all_breakpoints_safe): Make non-static. (iterate_over_breakpoints): Remove. * python/py-finishbreakpoint.c (bpfinishpy_detect_out_scope_cb): Return void. * python/py-breakpoint.c (build_bp_list): Add comment, reverse return value logic. * guile/scm-breakpoint.c (bpscm_build_bp_list): Return void.

gdb: add breakpoint::locations method
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. gdb/ChangeLog: * breakpoint.h (bp_locations_range): New.

gdb: add all_tracepoints function
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. (struct tracepoint_filter): New. (tracepoint_iterator): New. (tracepoint_range): New. (all_tracepoints): New. * breakpoint.c (ALL_TRACEPOINTS): Remove, replace all users with all_tracepoints. (breakpoint_iterator): Move to header. (all_tracepoints): New. * tracepoint.c (start_tracing): Adjust. Change-Id: I76b1bba4215dbec7a03846c568368aeef7f1e05a |

gdb/breakpoint: add a 'force_condition' parameter to 'create_breakpoint'
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.)
$ gdb -q --interpreter=mi3 /tmp/simple
=thread-group-added,id="i1"

^done
(gdb)
After applying this patch, we get the behavior below:
(gdb)
-break-insert -c junk -f main
^error,msg="No symbol \"junk\" in current context."
This restores the behavior that is present in the existing releases.
gdb/ChangeLog:
2021-04-21 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com>
* breakpoint.h (create_breakpoint): Add a new parameter,
'force_condition'.
* breakpoint.c (create_breakpoint): Use the 'force_condition'

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

gdb/breakpoint: add flags to 'condition' and 'break' commands to force condition
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.

gdb/breakpoint: disable a bp location if condition is invalid at that location
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:

[gdb/breakpoint] Handle setting breakpoint on label without address
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.

Recognize more program breakpoint patterns
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:

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.

gdb: Remove vec.{c,h} and update code to not include vec.h
Removes vec.c and vec.h from the source tree, and remove all the
remaining includes of vec.h. There should be no user visible changes

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:

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. Tested by the buildbot. gdb/ChangeLog 2019-07-09 Tom Tromey <tom@tromey.com> * contrib/ari/gdb_ari.sh: Change common to gdbsupport. * configure: Rebuild. * configure.ac: Change common to gdbsupport. *

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"}
gdb/ChangeLog:
* NEWS: Mention new MI commands.
* break-catch-throw.c (enum exception_event_kind): Move to
breakpoint.h.
(print_mention_exception_catchpoint): Output text as a single
message.

Revert the header-sorting patch
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. gdb/ChangeLog 2019-04-05 Tom Tromey <tom@tromey.com> Revert the header-sorting patch. * ft32-tdep.c: Revert. * frv-tdep.c: Revert. * frv-linux-tdep.c: Revert. * frame.c: Revert. * frame-unwind.c: Revert. * frame-base.c: Revert. * fork-child.c: Revert. * findvar.c: Revert. * findcmd.c: Revert. * filesystem.c: Revert. * filename-seen-cache.h: Revert. * filename-seen-cache.c: Revert. * fbsd-tdep.c: Revert. * fbsd-nat.h: Revert. * fbsd-nat.c: Revert. * f-valprint.c: Revert. * f-typeprint.c: Revert. * f-lang.c: Revert. * extension.h: Revert. * extension.c: Revert. * extension-priv.h: Revert. * expprint.c: Revert. * exec.h: Revert. * exec.c: Revert. * exceptions.c: Revert. * event-top.c: Revert. * event-loop.c: Revert. * eval.c: Revert. * elfread.c: Revert. * dwarf2read.h: Revert. * dwarf2read.c: Revert. * dwarf2loc.c: Revert. * dwarf2expr.h: Revert. * dwarf2expr.c: Revert. * dwarf2-frame.c: Revert. * dwarf2-frame-tailcall.c: Revert. * dwarf-index-write.h: Revert. * dwarf-index-write.c: Revert. * dwarf-index-common.c: Revert. * dwarf-index-cache.h: Revert. * dwarf-index-cache.c: Revert. * dummy-frame.c: Revert. * dtrace-probe.c: Revert. * disasm.h: Revert. * disasm.c: Revert. * disasm-selftests.c: Revert. * dictionary.c: Revert. * dicos-tdep.c: Revert. * demangle.c: Revert. * dcache.h: Revert. * dcache.c: Revert. * darwin-nat.h: Revert. * darwin-nat.c: Revert. * darwin-nat-info.c: Revert. * d-valprint.c: Revert. * d-namespace.c: Revert. * d-lang.c: Revert. * ctf.c: Revert. * csky-tdep.c: Revert. * csky-linux-tdep.c: Revert. * cris-tdep.c: Revert. * cris-linux-tdep.c: Revert. * cp-valprint.c: Revert. * cp-support.c: Revert. * cp-namespace.c: Revert. * cp-abi.c: Revert. * corelow.c: Revert. * corefile.c: Revert. * continuations.c: Revert. * completer.h: Revert. * completer.c: Revert. * complaints.c: Revert. * coffread.c: Revert. * coff-pe-read.c: Revert. * cli-out.h: Revert. * cli-out.c: Revert. * charset.c: Revert. * c-varobj.c: Revert. * c-valprint.c: Revert. * c-typeprint.c: Revert. * c-lang.c: Revert. * buildsym.c: Revert. * buildsym-legacy.c: Revert. * build-id.h: Revert. * build-id.c: Revert. * btrace.c: Revert. * bsd-uthread.c: Revert. * breakpoint.h: Revert. * breakpoint.c: Revert. * break-catch-throw.c: Revert. * break-catch-syscall.c: Revert. * break-catch-sig.c: Revert. * blockframe.c: Revert. * block.c: Revert. * bfin-tdep.c: Revert. * bfin-linux-tdep.c: Revert. * bfd-target.c: Revert. * bcache.c: Revert. * ax-general.c: Revert. * ax-gdb.h: Revert. * ax-gdb.c: Revert. * avr-tdep.c: Revert. * auxv.c: Revert. * auto-load.c: Revert. * arm-wince-tdep.c: Revert. * arm-tdep.c: Revert. * arm-symbian-tdep.c: Revert. * arm-pikeos-tdep.c: Revert. * arm-obsd-tdep.c: Revert. * arm-nbsd-tdep.c: Revert. * arm-nbsd-nat.c: Revert. * arm-linux-tdep.c: Revert. * arm-linux-nat.c: Revert. * arm-fbsd-tdep.c: Revert. * arm-fbsd-nat.c: Revert. * arm-bsd-tdep.c: Revert. * arch-utils.c: Revert. * arc-tdep.c: Revert. * arc-newlib-tdep.c: Revert. * annotate.h: Revert. * annotate.c: Revert. * amd64-windows-tdep.c: Revert. * amd64-windows-nat.c: Revert. * amd64-tdep.c: Revert. * amd64-sol2-tdep.c: Revert. * amd64-obsd-tdep.c: Revert. * amd64-obsd-nat.c: Revert. * amd64-nbsd-tdep.c: Revert. * amd64-nbsd-nat.c: Revert. * amd64-nat.c: Revert. * amd64-linux-tdep.c: Revert. * amd64-linux-nat.c: Revert. * amd64-fbsd-tdep.c: Revert. * amd64-fbsd-nat.c: Revert. * amd64-dicos-tdep.c: Revert. * amd64-darwin-tdep.c: Revert. * amd64-bsd-nat.c: Revert. * alpha-tdep.c: Revert. * alpha-obsd-tdep.c: Revert. * alpha-nbsd-tdep.c: Revert. * alpha-mdebug-tdep.c: Revert. * alpha-linux-tdep.c: Revert. * alpha-linux-nat.c: Revert. * alpha-bsd-tdep.c: Revert. * alpha-bsd-nat.c: Revert. * aix-thread.c: Revert. * agent.c: Revert. * addrmap.c: Revert. * ada-varobj.c: Revert. * ada-valprint.c: Revert. * ada-typeprint.c: Revert. * ada-tasks.c: Revert. * ada-lang.c: Revert. * aarch64-tdep.c: Revert. * aarch64-ravenscar-thread.c: Revert. * aarch64-newlib-tdep.c: Revert. * aarch64-linux-tdep.c: Revert. * aarch64-linux-nat.c: Revert. * aarch64-fbsd-tdep.c: Revert. * aarch64-fbsd-nat.c: Revert. * aarch32-linux-nat.c: Revert. |

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. In particular, bp_location_ops is now removed, and the "dtor" function pointer is replaced with an ordinary destructor. gdb/ChangeLog 2019-02-15 Philippe Waroquiers <philippe.waroquiers@skynet.be> Tom Tromey <tromey@adacore.com> * breakpoint.c (~bp_location): Rename from bp_location_dtor.

Update copyright year range in all GDB files.
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. |

Use std::vector for moribund_locations
This changes moribund_locations to use a std::vector rather than VEC. I also noticed that moribund_locations is only used in breakpoint.c, so now it is static as well. It might be possible to make this code a bit simpler by using a ref_ptr in moribund_locations; however, I have not done this. Tested by the buildbot. gdb/ChangeLog 2018-07-10 Tom Tromey <tom@tromey.com> * breakpoint.c (moribund_locations): Now static and a std::vector. (breakpoint_init_inferior, moribund_breakpoint_here_p) (build_bpstat_chain, update_global_location_list) (breakpoint_retire_moribund): Update. * breakpoint.h (bp_location_p): Remove typedef. Don't declare VEC. |

Remove VEC from breakpoint
This removes a use of VEC from breakpoint.h, also removing the now-unnecessary breakpoint_p typedef. This patch fixes a latent memory leak in find_matching_tracepoint_location, which neglected to free the vector returned by all_tracepoints. Tested by the buildbot. gdb/ChangeLog 2018-07-03 Tom Tromey <tom@tromey.com> * tracepoint.c (process_tracepoint_on_disconnect, start_tracing) (stop_tracing, tstatus_command) (find_matching_tracepoint_location, merge_uploaded_tracepoints) (print_one_static_tracepoint_marker): Update. * breakpoint.c (static_tracepoints_here, all_tracepoints): Return std::vector. * breakpoint.h (breakpoint_p): Remove typedef. Don't declare VEC. (all_tracepoints, static_tracepoints_here): Return std::vector. |

Use thread_info and inferior pointers more throughout
This is more preparation bits for multi-target support. In a multi-target scenario, we need to address the case of different processes/threads running on different targets that happen to have the same PID/PTID. E.g., we can have both process 123 in target 1, and process 123 in target 2, while they're in reality different processes running on different machines. Or maybe we've loaded multiple instances of the same core file. Etc. To address this, in my WIP multi-target branch, threads and processes are uniquely identified by the (process_stratum target_ops *, ptid_t) and (process_stratum target_ops *, pid) tuples respectively. I.e., each process_stratum instance has its own thread/process number space. As you can imagine, that requires passing around target_ops * pointers in a number of functions where we're currently passing only a ptid_t or an int. E.g., when we look up a thread_info object by ptid_t in find_thread_ptid, the ptid_t alone isn't sufficient. In many cases though, we already have the thread_info or inferior pointer handy, but we "lose" it somewhere along the call stack, only to look it up again by ptid_t/pid. Since thread_info or inferior objects know their parent target, if we pass around thread_info or inferior pointers when possible, we avoid having to add extra target_ops parameters to many functions, and also, we eliminate a number of by ptid_t/int lookups. So that's what this patch does. In a bit more detail: - Changes a number of functions and methods to take a thread_info or inferior pointer instead of a ptid_t or int parameter. - Changes a number of structure fields from ptid_t/int to inferior or thread_info pointers. - Uses the inferior_thread() function whenever possible instead of inferior_ptid. - Uses thread_info pointers directly when possible instead of the is_running/is_stopped etc. routines that require a lookup. - A number of functions are eliminated along the way, such as: int valid_gdb_inferior_id (int num); int pid_to_gdb_inferior_id (int pid); int gdb_inferior_id_to_pid (int num); int in_inferior_list (int pid); - A few structures and places hold a thread_info pointer across inferior execution, so now they take a strong reference to the (refcounted) thread_info object to avoid the thread_info pointer getting stale. This is done in enable_thread_stack_temporaries and in the infcall.c code. - Related, there's a spot in infcall.c where using a RAII object to handle the refcount would be handy, so a gdb::ref_ptr specialization for thread_info is added (thread_info_ref, in gdbthread.h), along with a gdb_ref_ptr policy that works for all refcounted_object types (in common/refcounted-object.h). gdb/ChangeLog: 2018-06-21 Pedro Alves <palves@redhat.com> * ada-lang.h (ada_get_task_number): Take a thread_info pointer instead of a ptid_t.

Don't elide all inlined frames
This patch essentially causes GDB to treat inlined frames like "normal"
frames from the user's perspective. This means, for example, that when a
user sets a breakpoint in an inlined function, GDB will now actually stop
"in" that function.
Using the test case from breakpoints/17534,
3 static inline void NVIC_EnableIRQ(int IRQn)
4 {
5 volatile int y;
6 y = IRQn;
7 }
8
9 __attribute__( ( always_inline ) ) static inline void __WFI(void)
10 {
11 __asm volatile ("nop");
12 }
13
14 int main(void) {
15
16 x= 42;
17
18 if (x)
19 NVIC_EnableIRQ(16);
20 else
21 NVIC_EnableIRQ(18);
(gdb) b NVIC_EnableIRQ
Breakpoint 1 at 0x4003e4: NVIC_EnableIRQ. (2 locations)
(gdb) r
Starting program: 17534
Breakpoint 1, main () at 17534.c:19
19 NVIC_EnableIRQ(16);
Because skip_inline_frames currently skips every inlined frame, GDB "stops"
in the caller. This patch adds a new parameter to skip_inline_frames
that allows us to pass in a bpstat stop chain. The breakpoint locations
on the stop chain can be used to determine if we've stopped inside an inline
function (due to a user breakpoint). If we have, we do not elide the frame.
With this patch, GDB now reports that the inferior has stopped inside the
inlined function:
(gdb) r
Starting program: 17534
Breakpoint 1, NVIC_EnableIRQ (IRQn=16) at 17534.c:6
6 y = IRQn;
Many thanks to Jan and Pedro for guidance on this.
gdb/ChangeLog:
* breakpoint.c (build_bpstat_chain): New function, moved from
bpstat_stop_status.
(bpstat_stop_status): Add optional parameter, `stop_chain'.
If no stop chain is passed, call build_bpstat_chain to build it.
* breakpoint.h (build_bpstat_chain): Declare.
(bpstat_stop_status): Move documentation here from breakpoint.c.
* infrun.c (handle_signal_stop): Before eliding inlined frames,
build the stop chain and pass it to skip_inline_frames.
Pass this stop chain to bpstat_stop_status.
* inline-frame.c: Include breakpoint.h.
(stopped_by_user_bp_inline_frame): New function.
(skip_inline_frames): Add parameter `stop_chain'.
Move documention to inline-frame.h.
If non-NULL, use stopped_by_user_bp_inline_frame to determine
whether the frame should be elided.
* inline-frame.h (skip_inline_frames): Add parameter `stop_chain'.
Add moved documentation and update for new parameter.
gdb/testsuite/ChangeLog:
* gdb.ada/bp_inlined_func.exp: Update inlined frame locations
in expected breakpoint stop locations.
* gdb.dwarf2/implptr.exp (implptr_test_baz): Use up/down to
move to proper scope to test variable values.
* gdb.opt/inline-break.c (inline_func1, not_inline_func1)
(inline_func2, not_inline_func2, inline_func3, not_inline_func3):
New functions.
(main): Call not_inline_func3.
* gdb.opt/inline-break.exp: Start inferior and set breakpoints at
inline_func1, inline_func2, and inline_func3. Test that when each
breakpoint is hit, GDB properly reports both the stop location
and the backtrace. Repeat tests for temporary breakpoints.

Use counted_command_line everywhere
Currently command lines are reference counted using shared_ptr only when attached to breakpoints. This patch changes gdb to use shared_ptr in commands as well. This allows for the removal of copy_command_lines. Note that the change to execute_user_command explicitly makes a new reference to the command line. This will be used in a later patch. This simplifies struct command_line based on the observation that a given command can have at most two child bodies: an "if" can have both "then" and "else" parts. Perhaps the names I've chosen for the replacements here are not very good -- your input requested.
