Summary:
This patch adds a CMake option LLDB_BUILD_FRAMEWORK, which builds libLLDB as a macOS framework instead of as a *nix shared library.
With this patch any LLDB executable that has the INCLUDE_IN_FRAMEWORK option set will be built into the Framework's resources directory, and a symlink to the exeuctable will be placed under the build directory's bin folder. Creating the symlinks allows users to run commands from the build directory without altering the workflow.
The framework generated by this patch passes the LLDB test suite, but has not been tested beyond that. It is not expected to be fully ready to ship, but it is a first step.
With this patch binaries that are placed inside the framework aren't being properly installed. Fixing that would increase the patch size significantly, so I'd like to do that in a follow-up.

This change does not introduce static bindings. It is simply using
the pylinted cleaned up code in prepare_bindings.py.
If this breaks anyting, I'll revert immediately and figure out what
needs to be addressed. I'm looking to wrap up
the cleanup aspect of the code change (pylinted, removal of code that
implements existing python stdlib code, fixes for Xcode adoption, etc.).

Python has a complicated mechanism of checking an objects truthity.
This involves a number of steps, which end with calling two private
methods on an object (if they are implemented). In Python 2 these
two methods are `__nonzero__` and `__len__`, and in Python 3 they
are `__bool__` and `__len__`. Because we *also* define a __len__
method for certain iterable types, this was triggering a situation
in Python 3 where `__nonzero__` wasn't defined, so it was calling
`__len__`, which was returning 0 (for example an SBDebugger with
no targets), and as a result the truthosity was determined to be
False.
We fix this by correctly using ` __bool__` for Python 3, and leave
the behavior under Python 2 unchanged.
Note that this fix is only implemented in the SWIG generation
python script, and not the SWIG generation shell script. Someone
more familiar than me with shell scripts will need to fix them
to support this for Python 3 if desired.
llvm-svn: 252382
Summary:
This should be a mandatory build process going forward, if Python
is enabled. The longer term desire is to remove the old shell
scripts entirely.

Summary:
Move scripts/Python/interface to scripts/interface so that we
can start making iterative improvements towards sharing the
interface files between multiple languages (each of which would
have their own directory as now).
Test Plan: Build and see.

Previously it would only regenerate LLDBWrapPython.cpp if one of
the .i files changed, or if lldb.swig changed. This patch also
makes it depend on the rest of the *.swig files, so that if any
of them changes it regenerates the CMake.

This is generating problems when you have built both debug and
release python. For now I just want to get CMake to work, I
will work on a more robust fix later. In the meantime you may
need to copy python27(_d).dll manually to ninja\bin after
building.
llvm-svn: 230379
On Windows we copy python27(_d).dll to the bin directory. We do
this by looking at the PYTHON_LIBRARY specified by the user, which
is something like C:\foo\python27_d.lib, and replacing ".lib" with
".dll". But ".lib" as a regex will also match "flib", etc. So
make this a literal . instead of a wildcard .

This reverts commit r226679. For some reason it was
not generating the same behavior as manually specifying
the include dir, library path, and exe path, and it was
causing the test suite to fail to run.

CMake FindPythonLibs will look for multiple versions of Python
including both debug and release, and build up a list such as
(debug <debugpath> optimized <optimizedpath>). This confuses
the logic we have in CMake to copy the correct python dll to
the output directory so that it need not be in your system's PATH.
To alleviate this, we manually split this list and extract out
the debug and release versions of the python library, and copy
only the correct one to the output directory.

`ninja lldb` used to always run "echo -n", which on OS X results in literally
echoing "-n" to the screen. Just remove the command from add_custom_target,
then it only adds an alias and `ninja lldb` now reports "no work to do".
Other than that, no intended behavior change.

When Python does not exist on the system path, LLDB will be unable
to load it. Fix this by copying the dll to the output folder so
it will be side-by-side with lldb.exe.

SWIG is searched under certain paths within python script. CMake can
detect SWIG with find_package(SWIG). This is used iff user checks
LLDB_ENABLE_PYTHON_SCRIPTS_SWIG_API_GENERATION. If
buildSwigWrapperClasses.py does not receive swigExecutable argument,
then the script will use its current search implementation.

_lldb is built as an extension module on Windows. Normally to load
an extension module named 'foo', Python would look for the file
'foo.pyd'. However, when a debug interpreter is used, Python will
look for the file 'foo_d.pyd'. This change checks the build
configuration and creates the correct symlink name based on the
build configuration.
llvm-svn: 213306
Being in lldb\source, ${CMAKE_CURRENT_BINARY_DIR} would resolve to
the build\tools\lldb\source directory. For correct operation, and
parity with the shell script, it needs to resolve to the
build\tools\lldb\scripts directory.

- Ported the SWIG wrapper shell scripts to Python so that they would work on Windows too along with other platforms
- Updated CMake handling to fix SWIG errors and manage sym-linking on Windows to liblldb.dll
- More build fixes for Windows
The pending issues are that two Python modules, termios and pexpect are not available on Windows.
These are currently required for the Python command interpreter to be used from within LLDB.

command instead of a script.
In addition to cleaning things up, this allows more easy access to the
variables. In the old version, it tried to pass variables as -D flags to
cmake, but this didn't actually work. CMake drops all of those arguments
on the floor (try passing garbage through them) and just picks up the
limited subset of pre-defined macros. So, for example, this fixes the
build with LLVM_LIBDIR_SUFFIX=64 which is how I ended up here. =]

The FreeBSD package building cluster installs e.g. 'python2.7', but no
plain 'python' to avoid version-related issues.
CMake's FindPythonInterp locates an interpreter with such a name and
provides it in the PYTHON_EXECUTABLE variable. Use that if it's set,
falling back to the original '/usr/bin/env python' otherwise.

Bug fix for pr18841:
http://llvm.org/bugs/show_bug.cgi?id=18841
This change creates a stub Python readline.so module that does almost
nothing. Its whole purpose is to prevent Python from loading the real
module, something it does during the embedded Python interpreter's
initialization sequence (and way before lldb ever requests it within
embedded_interpreter.py).
On Ubuntu 12.04 and 13.10 x86_64, and in the Python 2.7.6 tree, the
stock Python readline module links against the GNU readline library.
This appears to be the case on all Pythons except where __APPLE__ is
defined. LLDB now requires linking against the libedit library.
Something about having both libedit.so and libreadline.so linked into
the same process space is causing the Python readline.so to trigger a
NULL memory access. I have put in a separate patch to python.org.
This suppression of embedded interpreter readline support can be
removed if at least any one of the following happens:
1. The stock python distribution accepts a patch similar to what I
submitted to Python 2.7.6's Modules/readline.c file.
2. The stock python distribution implements Modules/readline.c in
terms of libedit's readline compatibility mode (i.e. essentially
compiles it the way __APPLE__ compiles that module) under Linux.
3. a clean-room implementation of the python readline module is
implemented against libedit (either readline compatibility mode or
native libedit). This could be implemented within the readline.cpp
file that this change introduces. It cannot be a fork of python's
readline.c module due to llvm licensing.
The net effect of this change on Linux is that the embedded python's
readline support will not exist.

- copy lldb python module into directory specified with CMAKE_INSTALL_PREFIX
- make liblldb.so a symlink (to liblldb.so.X.Y where X.Y is the LLVM version)

Two reasons for that:
* the declaration is not used. the LLDB_SOURCE_DIR is provided as the first argument in the script ($1) (called SRC_ROOT in the source code)
* add_custom_command is quoting the first argument of the command. Usually, it is the script itself (and then the full path to the script) but, here, it is the declaration of a variable.
It was failing with:
