Currently, there is no option to delete all the watchpoint without LLDB
asking for a confirmation. Besides making the watchpoint delete command
homogeneous with the breakpoint delete command, this option could also
become handy to trigger automated watchpoint deletion i.e. using
breakpoint actions.

Summary:
We currently don't set access specifiers for function template declarations. This seems to be fine
as long as the function template is not declared inside any record in which case Clang asserts
with the following once we try to query it's access:
```
Assertion failed: (Access != AS_none && "Access specifier is AS_none inside a record decl"), function AccessDeclContextSanity,
```
This patch just marks these function template declarations as public to make Clang happy.

Now that we are building the python bindings on Windows once more, the
extended testsuite is running. Mark a few failing tests and skip a few
tests which hang. This should at least bring the bot back to green
without reverting the Python changes which are an improvement for the
build system and enable another ~35% of the test suite which was
previously disabled.
This patch adds skipif decorator to TestWatchLocationWithWatchSet.py.
Decorator will trigger for aarch64-linux as this test passes randomly
causing buildbot failure.
This fix was motivated by a crashes in expression parsing during code generation in which we had a RecordDecl that had incomplete FieldDecl. During code generation when computing the layout for the RecordDecl we crash because we have several incomplete FieldDecl.
This fixes the issue by assuring that during ImportDefinition(...) for a RecordDecl we also import the definitions for each FieldDecl.

Summary:
A lot of our tests copied the setUp code from our TestSampleTest.py:
```
def setUp(self):
# Call super's setUp().
TestBase.setUp(self)
```
This code does nothing unless we actually do any setUp work in there, so let's remove all these method definitions.

Summary:
A lot of tests do this trick but the vast majority of them don't even call `print()`.
Most of this patch was generated by a script that just looks at all the files and deletes the line if there is no `print (` or `print(` anywhere else in the file.
I checked the remaining tests manually and deleted the import if we never call print (but instead do stuff like `expr print(...)` and similar false-positives).
I also corrected the additional empty lines after the import in the files that I manually edited.

Summary:
This was causing problems on linux, where we'd end up calling the
deleting destructor instead of a regular one (because they have the same
demangled name), making a lot of mischief in the process.
The only place where this was necessary (according to the test suite, at
least) was to call a base structor instead of a complete one, but this
is now handled in a more targeted fashion.
TestCallOverriddenMethod is now re-enabled as it now passes reliably.

I have either opened new bug reports for these tests, or added links to
existing bugs.
This should help make the lldb-aarch64-ubuntu buildbot green (there will
still be some unexpected passes that someone should look into, but those
can be handled later).
NetBSD ptrace interface does not populate watchpoints to newly-created
threads. Solve this via copying the watchpoints from the current thread
when new thread is reported via TRAP_LWP.
Add a test that verifies that when the user does not have permissions
to set watchpoints on NetBSD, the 'watchpoint set' errors out gracefully
and thread monitoring does not crash on being unable to copy watchpoints
to new threads.

Implement major improvements to multithreaded program support. Notably,
support tracking new and exited threads, associate signals and events
with correct threads and support controlling individual threads when
resuming.
Firstly, use PT_SET_EVENT_MASK to enable reporting of created and exited
threads via SIGTRAP. Handle TRAP_LWP events to keep track
of the currently running threads.
Secondly, update the signal (both generic and SIGTRAP) handling code
to account for per-thread signals correctly. Signals delivered
to the whole process are reported on all threads, while per-thread
signals and events are reported only to the specific thread.
The remaining threads are marked as 'stopped with no reason'. Note that
NetBSD always stops all threads on debugger events.
Thirdly, implement the ability to set every thread as running, stopped
or single-stepping separately while continuing the process. This also
provides the ability to send a signal to the whole process or to one
of its thread while resuming.

Summary:
To run the testsuite remotely the executable needs to be uploaded to
the target system. The Target takes care of this by default.
When the test uses additional shared libraries, those won't be handled
by default and need to be registered with the target using
test.registerSharedLibrariesWithTarget(target, dylib).
Calling this API requires a target, so it doesn't mesh well with the
run_to_* helpers that we've been advertising as the right way to write
tests.
This patch adds an extra_images argument to all the helpers and does
the registration automatically when running a remote
testsuite. TestWeakSymbols.py was converted to use this new scheme.

TestFormatters.py has a sequence of three 'next' commands to get past
all the initializations in the test function. On AArch64 (and
potentially other platforms), this was one 'next' too many and we ended
up outside our frame.
This patch replaces the sequence with a 'thread until ' the line of the
return from the function, so we should stop after all the
initializations but before actually returning.

Add info for all register sets supported in NetBSD, particularly for all
registers 'expected' by LLDB. This is necessary in order to fix
python_api/lldbutil/iter/TestRegistersIterator.py test that currently
fails due to missing names of register sets (None).
This copies fpreg descriptions from Linux, and combines Linux' AVX
and MPX registers into a single XState group, to fit NetBSD register
group design. Technically, we do not support MPX registers
at the moment but gdb-remote insists on passing their errors anyway,
and if we do not include it in any group, they end up in a separate
anonymous group that breaks the test.
While at it, swap the enums for XState and DBRegs to match register set
ordering.
This also adds a few consts to the lldb-x86-register-enums.h to provide
more consistency between user registers and debug registers.
Differential Revision: https://reviews.llvm.org/D69667
Summary:
This change increases the offset of MPX registers (by 128) so they
do not overlap with the offset associated with AVX registers. That was
causing MPX data in GDBRemoteRegisterContext::m_reg_data to get overwritten.

Summary:
So far we rely on the default argument and the fact that we don't call this
inline function in our actual `main.cpp` to make sure that this function can only
be called if LLDB loads this header as a C++ module. This patch just adds
the nodebug attribute as yet another measure to make sure LLDB can't call this
function without the standard module loaded. Note that the test is already
requiring clang for the sysroot setup, so its fine that this is a Clang specific attribute.

Summary:
When users define a debugger command from python, they provide a callable
object. Because the signature of the function has been extended, LLDB
needs to inspect the number of parameters the callable can take.
The rule it was using to decide was weird, apparently not tested, and
giving wrong results for some kinds of python callables.
This patch replaces the weird rule with a simple one: if the callable can
take 5 arguments, it gets the 5 argument version of the signature.
Otherwise it gets the old 4 argument version.
It also adds tests with a bunch of different kinds of python callables
with both 4 and 5 arguments.

We call these tests in the second test function where they are
x-failed on Windows. I forgot to remove the tests from the first
test function (which is not x-failed on Windows) when extracting these
calls into their own test function, so the test is still failing on Windows.
llvm-svn: 375271
These tests were testing a bug related to constructors. It seems that
on Windows the expression command can't construct objects (or at least,
call their constructor explicitly which is required for the tests), so
this is just x-failing them until Windows actually supports constructor calls.
llvm-svn: 375173
Summary:
When we have a artificial constructor DIE, we currently create from that a global function with the name of that class.
That ends up causing a bunch of funny errors such as "must use 'struct' tag to refer to type 'Foo' in this scope" when
doing `Foo f`. Also causes that constructing a class via `Foo()` actually just calls that global function.
The fix is that when we have an artificial method decl, we always treat it as handled even if we don't create a CXXMethodDecl
for it (which we never do for artificial methods at the moment).
Fixes rdar://55757491 and probably some other radars.

We essentially test libc++ in a sysroot here so let's make sure
that we actually only run this test on platforms where libc++
testing is enabled.
llvm-svn: 374572
We currently don't handle the error in the Expected we get
when searching for an equal local DeclContext. Usually this can't
happen as this would require that we have a STL container and
we can find libc++'s std module, but when we load the module in
the expression parser the module doesn't even contain the 'std'
namespace. The only way I see to test this is by having a fake
'std' module that requires a special define to actually provide
its contents, while it will just be empty (that is, it doesn't
even contain the 'std' namespace) without that define. LLDB currently
doesn't know about that define in the expression parser, so it
will load the wrong 'empty' module which should trigger this error.
Also removed the 'auto' for that variable as the function name
doesn't make it obvious that this is an expected and not just
a optional/ptr (which is how this slipped in from the start).
