Summary:
LLDB doesn't use this code, the code has no tests, and the code does suspicious
things like hashing pointers to strings instead of the strings themselves.

This test uses XML packets, but libxml is an optional dependency of
lldb, and this test fails if it is not present.
I'm leaving this enabled on mac, as thats the only platform that's
likely to have libxml always available, but ideally we should have a way
to skip this based on build configuration. I'll see if I can whip
something like that up soon, but for the time being, this unblocks the
buildbots.

This patch makes LLDB's clang module cache path customizable via

This only worked on MacOS, which now ships a newer version of
python without this bug. As such, we don't leak the fd, and
this test is not needed anymore (as it also hardcoded the python
version in the check).

Summary:
Right now the test client is not parsing register values correctly,
which is manifesting itself in one test failing on 32-bit architectures
(pr36013). This parses the information from the qRegisterInfo packets
and stores it in the client, which will enable fixing the parsing in a
follow up commit.
I am also adding a new templated SendMessage overload, which enables one
to send a message get a parsed response in a single call.

Summary:
This is combination of following changes,
- Resolve function symbols in PDB symbol file. `lldb-test symbols` will display information about function symbols.
- Implement SymbolFilePDB::FindFunctions methods. On lldb console, searching function symbol by name and by regular expression are both available.
- Create lldb type for PDBSymbolFunc.
- Add tests to check whether functions with the same name but from different sources can be resolved correctly.

Summary:
The test was trying to reproduce a bug in handling of two concurrent
events, which was impossible to do reliably in a black-box style test.
In practice, this meant the test was only ever failing on remote
targets, as these were slow enough to trigger this.
Fortunately, we now have the ability to mock the server side of the
connection, which means we can simulate the failure deterministically,
so I rewrite the test to use the new gdb-client framework.
I've needed to add a couple of new packets to the mock server to be able
to do this. Instead of trying to guess how a "typical" gdb-client test
will want to handle this, I throw an exception in the implementation to
force the user to override them (the packets are only sent if the test
explicitly performs some action which will trigger them, so a basic test
which e.g. does not need the "continue" functionality will not need to
implement them).

Summary:
This is a small change towards running the LLDB unit tests on Windows (still WIP).
Builds that use make do not point to specific configurations. However, builds with multiple configurations such as Visual Studio on Windows need the configuration (release/debug/etc) as part of the path so the binaries produced by clang are placed in the correct directory for the configuration.

Inlined tests have a test function that is actually an instance method,
which requires a slightly different approach when it comes to setting
the category attribute. The attribute must be set on the actual
function, rather than on a particular instance.

This patch creates a <test>.dwarf, <test>.dwo, etc., build directory for each testcase variant.
Most importantly, this eliminates the need for the per-test lock file in the source directory.
Tests that are marked as NO_DEBUG_INFO_TESTCASE and build with
buildDefault() are built in a <test>.default build directory.

Davide pointed out this would be useful if the file ever needs to be
regenerated (and I certainly agree).
I also replace the test binary with a slightly smaller one -- I intended
to do this in the original commit, but I forgot to add it to the patch
as I was juggling several things at the same time.

ObjectFileELF::GetModuleSpecifications contained a lot of tip-toing code
which was trying to avoid loading the full object file into memory. It
did this by trying to load data only up to the offset if was accessing.
However, in practice this was useless, as 99% of object files we
encounter have section headers at the end, so we would load the whole
file as soon as we start parsing the section headers.
In fact, this would break as soon as we encounter a file which does
*not* have section headers at the end (yaml2obj produces these), as the
access to .strtab (which we need to get the section names) was not
guarded by this offset check.
As this strategy was completely ineffective anyway, I do not attempt to
proliferate it further by guarding the .strtab accesses. Instead I just
lead the full file as soon as we are reasonably sure that we are indeed
processing an elf file.
If we really care about the load size here, we would need to reimplement
this to just load the bits of the object file we need, instead of
loading everything from the start of the object file to the given
offset. However, given that the OS will do this for us for free when
using mmap, I think think this is really necessary.
For testing this I check a (tiny) SO file instead of yaml2obj-ing it
because the fact that they come out first is an implementation detail of
yaml2obj that can change in the future.

Summary:
We cannot call process_up->SetState() inside
the NativeProcessNetBSD::Factory::Launch
function because it triggers a NULL pointer
deference.
The generic code for launching a process in:
GDBRemoteCommunicationServerLLGS::LaunchProcess
sets the m_debugged_process_up pointer after
a successful call to m_process_factory.Launch().
If we attempt to call process_up->SetState()
inside a platform specific Launch function we
end up dereferencing a NULL pointer in
NativeProcessProtocol::GetCurrentThreadID().
Use the proper call process_up->SetState(,false)
that sets notify_delegates to false.

Summary:
This changes the way we store the debug info variant to make it
available earlier in the test bringup: instead of it being set by the
test wrapper method, it is set as a *property* of the wrapper method.
This way, we can inspect it as soon as self.testMethodName is
initialized. The retrieval is implemented by a new function
TestBase.getDebugInfo(), and all that's necessary to make it work is to
change self.debug_info into self.getDebugInfo().
While searching for debug_info occurences i noticed that TestLogging is
being replicated for no good reason, so I removed the replication there.

I have found LLDB cannot find separate debug info of Fedora /usr/bin/gdb.
It is because:
lrwxrwxrwx 1 root root 14 Jan 25 20:41 /usr/bin/gdb -> ../libexec/gdb*
-rwxr-xr-x 1 root root 10180296 Jan 25 20:41 /usr/libexec/gdb*
ls: cannot access '/usr/lib/debug/usr/bin/gdb-8.0.1-35.fc27.x86_64.debug': No such file or directory
-r--r--r-- 1 root root 29200464 Jan 25 20:41 /usr/lib/debug/usr/libexec/gdb-8.0.1-35.fc27.x86_64.debug
FYI that -8.0.1-35.fc27.x86_64.debug may look confusing, it was always just
.debug before.
Why is /usr/bin/gdb a symlink is offtopic for this bugreport, Fedora has it so
for some reasons.
It is always safest to look at the .debug file only after resolving all
symlinks on the binary file.
