With the growing number of selftests, I think it would be useful to be
able to run only a subset of the tests. This patch associates a name to
each registered selftest. It then allows doing something like:
(gdb) maintenance selftest aarch64
Running self-tests.
Running selftest aarch64-analyze-prologue.
Running selftest aarch64-process-record.
Ran 2 unit tests, 0 failed
or with gdbserver:
./gdbserver --selftest=aarch64
In both cases, only the tests that contain "aarch64" in their name are
ran. To help validate that the tests you want to run were actually ran,
it also prints a message with the test name before running each test.
Right now, all the arch-dependent tests are registered as a single test
of the selftests. To be able to filter those too, I made them
"first-class citizen" selftests. The selftest type is an interface,
with different implementations for "simple selftests" and "arch
selftests". The run_tests function simply iterates on that an invokes
operator() on each test.
I changed the tests data structure from a vector to a map, because
- it allows iterating in a stable (alphabetical) order
- it allows to easily verify if a test with a given name has been
registered, to avoid duplicates
There's also a new command "maintenance info selftests" that lists the
registered selftests.

This is a followup patch to the build breakage fix on AArch64. While
doing the fix, I found it better to convert tdesc->reg_defs (on
gdbserver/tdesc.h) from using VEC to using std::vector. This makes
the code easier to read and maintain, and also is one more step
towards the C++fication.
Regtested on BuildBot.

Note this brings in the interface files for libcc1/G++ as well, which
we will be needing in GDB soon anyway. That commit renamed a method
in the C interface and that required a small update to GDB's compile/

building.

As explained in the previous patch, the gdb_id concept is no longer
relevant. The function thread_to_gdb_id is trivial, it returns the

From what I understand, this function is not doing anything useful as of
today.
Here's the result of my archeological research:
- The field thread_info::gdb_id was added in
a06660f7 Use LWP IDs for thread IDs in gdbserver
There was problem when using a 32-bits gdb with a 64-bits gdbserver.
For some reason that I don't fully understand, the thread ids
exchanged between gdb and gdbserver could overflow a 32 bits data
type. My guess is that they were the thread address (e.g. the
0x7ffff7f20b40 in "Thread 0x7ffff7f20b40 (LWP 1058)" today). This
patch changed that so gdb/gdbserver would talk in terms of the OS
assigned numerical id (as shown in ps). It therefore added a way to
convert between this gdb_id (the numerical id) and the thread id (the
address).
- 95954743cb Implement the multiprocess extensions, and add linux
multiprocess supportNon-stop mode support.
This patch made gdbserver deal with threads using their numerical ids
and not the address-like id. Starting from there, the gdb_id <->
thread id conversion was not needed anymore, since the remote protocol
and gdbserver were using the same kind of ids again. The gdb_id field
in the thread_info structure was also unused starting there.
- d50171e4 Teach linux gdbserver to step-over-breakpoints.
This patch moved the thread_info structure around, and got rid of the
gdb_id field (which was unused).
Looking at the implementation of gdb_id_to_thread_id, it is not doing
anything useful. It is looking up a thread by ptid using
find_thread_ptid, which basically loops over all threads looking at
their entry.id field. If a thread with that ptid is found, it returns
its entry.id field. So it will always return the same thing as it input
(with the exception of if no thread exist with that ptid, then it will
return null_ptid).

* inferiors.h (gdb_id_to_thread_id): Remove.
* inferiors.c (gdb_id_to_thread_id): Remove.
* server.c (process_serial_event): Adjust to gdb_id_to_thread_id

The code required to handle the 'D' packet is non trivial, so move it
out to its own function.

We used to silently truncate the size returned by stat() to 32 bits.
While it is possible to make binutils handle a 64-bit off_t on a

Instead, error if we truncate the size. I've written the test the way
I have to avoid a signed/unsigned warning.

Replace the manually managed array with a vector. It is mostly
straightforward, except maybe one thing in execute_stack_op, in the
handling of DW_OP_fbreg. When the code stumbles on that opcode while
evaluating an expression, it needs to evaluate a subexpression to find
where the fb reg has been saved. Rather than creating a new context, it
reuses the current context. It saves the size of the stack before and
restores the stack to that size after.
I think we can do a little bit better by saving the current stack
locally and installing a new empty stack. This way, if the
subexpression is malformed and underflows, we'll get an exception.
Before, it would have overwritten the top elements of the top-level
expression. The evaluation of the top-level expression would have then
resumed with the same stack size, but possibly some corrupted elements.

I'm seeing these failures on my system:

The problem is simply that GDB is finding a symbol named "mult" from

"sec" gets set to NULL on errors in the offset expression. This patch
disables part of the reloc expression processing that needs "sec"
valid. I didn't disable the entire reloc expression handling so that
errors in the reloc expression are reported even when the offset
expression has an error.

This patch replaces the usage of VEC to store pointers to probe_ops with
an std::vector. The sole usage of that vector type is one global
variable that holds the ops for the various kinds of probes, so this is
pretty straightforward (no allocation/deallocation issues).

Change collect_probes so it returns an std::vector<bound_probe> instead
of a VEC(bound_probe_s). This allows removing some cleanups. It also
seems like enable_probes_command and disable_probes_command were not
freeing that vector.
The comparison function compare_probes needs to be updated to return a
bool indicating whether the first parameter is "less than" the second
parameter.
I defined two constructors to bound_probe. The default constructor is
needed, for example, so the instance in struct bp_location can be
constructed without parameters. The constructor with parameters is
useful so we can use emplace_back and pass the values directly.
The s390 builder on the buildbot shows a weird failure that I can't
explain:
../../binutils-gdb/gdb/elfread.c: In function void probe_key_free(bfd*, void*):
../../binutils-gdb/gdb/elfread.c:1346:8: error: types may not be defined in a for-range-declaration [-Werror]

^~~~~~
I guess it's a bug with that specific version< of the compiler, since no
other gcc gives me that error. It is using:
g++ (GCC) 6.3.1 20161221 (Red Hat 6.3.1-1)
Any idea about this problem?

This patch changes one usage of VEC to std::vector. It is a relatively
straightforward 1:1 change. The implementations of
sym_probe_fns::sym_get_probes return a borrowed reference to their probe
vectors, meaning that the caller should not free it. In the new code, I
made them return a const reference to the vector.

see any failures that looked related to this one.

Change extract_arg to return a std::string and fix up all the users.
I think string is mildly better than unique_xmalloc_ptr<char>, when
possible, because it provides a more robust API.
I changed the error messages emitted from find_location_by_number to
avoid either writing to a string or an extra allocation; this can be
changed but I thought that the new message was not any less clear.
You can see an example in the testsuite patch.

This renames a few functions -- skip_spaces_const,
skip_to_space_const, get_number_const, extract_arg_const -- to drop
the "_const" suffix and instead rely on overloading.
This makes future const fixes simpler by reducing the number of lines
that must be changed. I think it is also not any less clear, as all
these functions have the same interface as their non-const versions by
design. Furthermore there's an example of using an overload in-tree
already, namely check_for_argument.
This patch was largely created using some perl one-liners; then a few
fixes were applied by hand.

The first patch in this series went through several iterations as I'd
forgotten how many places had to be touched to add a new event and a
new event type.
This patch simplifies the process using two new ".def" files. Now, a
new event type can be added by adding a line to "py-event-types.def",
and a new event registry can be added by adding a line to
"py-all-events.def".
