PDB is Microsoft's debug information format, and although we
cannot yet generate it, we still must be able to consume it.
Reason for this is that debug information for system libraries
(e.g. kernel32, C Runtime Library, etc) only have debug info
in PDB format, so in order to be able to support debugging
of system code, we must support it.
Currently this code should compile on every platform, but on
non-Windows platforms the PDB plugin will return 0 capabilities,
meaning that for now PDB is only supported on Windows. This
may change in the future, but the API is designed in such a way
that this will require few (if any) changes on the LLDB side.
In the future we can just flip a switch and everything will
work.
This patch only adds support for line tables. It does not return
information about functions, types, global variables, or anything
else. This functionality will be added in a followup patch.

The Go interpreter doesn't JIT or use LLVM, so this also
moves all the JIT related code from UserExpression to a new class LLVMUserExpression.

Also added a placeholder Editline gtest for some code that I'll add as soon
as I make sure this addition doesn't break any of the build bots.
This change also introduces some Xcode user-defined variables that I've used
to attempt to isolate the way Python is integrated into the build. I don't have
the rest of LLDB using it yet, I'm using the gtests as my guinea pig on that.
Currently these are:
PYTHON_FRAMEWORK_PATH
PYTHON_VERSION_MAJOR
PYTHON_VERSION_MINOR
I will convert the rest over to it after this gets a little time to bake
and any kinks are worked out of it.

With this change, liblldb is 95% of the way towards being able
to work under both Python 2.x and Python 3.x. This should
introduce no functional change for Python 2.x, but for Python
3.x there are some important changes. Primarily, these are:
1) PyString doesn't exist in Python 3. Everything is a PyUnicode.
To account for this, PythonString now stores a PyBytes instead
of a PyString. In Python 2, this is equivalent to a PyUnicode,
and in Python 3, we do a conversion from PyUnicode to PyBytes
and store the PyBytes.
2) PyInt doesn't exist in Python 3. Everything is a PyLong. To
account for this, PythonInteger stores a PyLong instead of a
PyInt. In Python 2.x, this requires doing a conversion to
PyLong when creating a PythonInteger from a PyInt. In 3.x,
there is no PyInt anyway, so we can assume everything is a
PyLong.
3) PyFile_FromFile doesn't exist in Python 3. Instead there is a
PyFile_FromFd. This is not addressed in this patch because it
will require quite a large change to plumb fd's all the way
through the system into the ScriptInterpreter. This is the only
remaining piece of the puzzle to get LLDB supporting Python 3.x.
Being able to run the test suite is not addressed in this patch.
After the extension module can compile and you can enter an embedded
3.x interpreter, the test suite will be addressed in a followup.
llvm-svn: 249886
Previously embedded interpreters were handled as ad-hoc source
files compiled into source/Interpreter. This made it hard to
disable a specific interpreter, or to add support for other
interpreters and allow the developer to choose which interpreter(s)
were enabled for a particular build.
This patch converts script interpreters over to a plugin-based system.
Script interpreters now live in source/Plugins/ScriptInterpreter, and
the canonical LLDB interpreter, ScriptInterpreterPython, is moved there
as well.
Any new code interfacing with the Python C API must live in this location
from here on out. Additionally, generic code should never need to
reference or make assumptions about the presence of a specific interpreter
going forward.

Summary:
Since all TSC operations are now executed synchronously, TSC has become a little more than a
messenger between different parts of NativeProcessLinux. Therefore, the reason for its existance
has disappeared.
This commit moves the contents of the TSC into the NPL class. This will enable us to remove all
the boilerplate code in NPL (as it stands now, this is most of the class), which I plan to do in
subsequent commits.
Unfortunately, this also means we will lose the unit tests for the TSC. However, since the size
of the TSC has diminished, the unit tests were not testing much at this point anyway, so it's not
a big loss.
No functional change.

Summary:
Currently, linking of the unittests fails on linux because it is missing a bunch of symbols from
libedit, curses, etc. This fixes the build by adding the correct dependencies.

The order of libraries passed to the linker didn't work under linux (you
need the llvm libraries first, then the lldb libraries). I modelled this
after clang's setup here. Seemed simple enough to just be consistent.

A recent refactor had introduced a bug where if you escaped a
character, the rest of the string would get processed incorrectly.
This patch fixes that bug and adds some unit tests for Args.

Sigh. There's really not a good alternative until we decouple
python from lldb better. The only way the build works right now
is by having every executable link against every LLDB library.
This causes implicit transitive link dependencies on the union
of everything that LLDB brings in. Which means that if all we
want is one header file from interpreter, we have to bring in
everything, including everything that everything depends on,
which means python.
There's outstanding efforts to address this, but it's not yet
complete. So until then, this is all we can do.
llvm-svn: 232287
This makes the directory structure mirror the canonical LLVM
directory structure for a gtest suite.
Additionally, this patch deletes the xcode project. Nobody
is currently depending on this, and it would be better to have
gtest unit tests be hand-maintained in the Xcode workspace
rather than using this python test runner. Patches to that
effect will be submitted as followups.
