Jonas Devlieghere 52721286b2 [CMake] Unify and relayer testing
This patch restructures part of LLDB's testing configuration:

1. I moved the test dependencies up the chain so every dotest dependency
   becomes a lit dependency as well. It wouldn't make sense for dotest to
   have other dependencies when it's being run by lit. Lit on the other
   hand can still specify extra dependencies.

2. I replaced as much generator expressions with variables as possible.
   This is consistent with the rest of LLVM and doesn't break generators
   that support multiple targets (MSVC, Xcode). This wasn't a problem
   before, but now we need to expand the dotest arguments in the lit
   configuration and there's only one test suite even with multiple
   targets.

3. I moved lldb-dotest into it's own directory under utils since there's
   no need anymore for it to located under `test/`.

Aaron Smith 07482d32e7 [lit] Update how clang and other binaries are found in per-configuration directories
Summary:
This is modeled after the clang and llvm lit tests.

Several properties have CMAKE_CFG_INTDIR as part of the path - this works correctly when the cmake generator only supports one configuration which is known at configuration time, but it does not work correctly when the cmake generator supports multiple configurations (for example, VS). 

For VS, CMAKE_CFG_INTDIR ends up set as $Configuration and then it is never updated correctly. Instead, the lit configuration can use a property that can be overwritten at run time. AddLLVM does that for several properties (such as LLVM_TOOLS_DIR). 

This change is also removing properties from the lit/CMakeLists.txt that are actually set during the call to configure_lit_site_cfg

Don Hinton d8a6b90e83 [cmake] Fix LLDB_CODESIGN_IDENTITY logic.
Summary:
Consolidate LLDB_CODESIGN_IDENTITY logic in one place and use
SKIP_DEBUGSERVER, which can be set independently, to control
codesigning targets.

Currently, running cmake the first time in a clean directory, without
passing -DLLDB_CODESIGN_IDENTITY='', fails.  However, subsequent runs
succeed.  That's because LLDB_CODESIGN_IDENTITY gets added to the
CACHE after the initial test.  To fix that, the default value must be
set before it's tested.

Here's the error produced on the first run:

CMake Error at tools/lldb/tools/debugserver/source/CMakeLists.txt:215 (add_custom_command):
  No TARGET 'debugserver' has been created in this directory.

Aaron Smith 35cdfe2d1d Add CMAKE_CFG_INTDIR as part of the include path for the default test compiler.
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.

Pavel Labath 7e17fc5e09 Default to using in-tree clang for building test executables
Summary:
Using the in-tree clang should be the default test configuration as that
is the one compiler that we can be sure everyone has (better
reproducibility of test results). Also, it should hopefully reduce the
impact of pr35040.

This also reduces the number of settings which control the compiler
used. LLDB_TEST_C_COMPILER is used for C files and
LLDB_TEST_CXX_COMPILER for C++ files. Both of the settings default to
the in-tree clang.

Luke Drummond c3d0165c49 Fix broken escaping of commands in the build
A combination of broken escaping in CMake and in the python swig
generation scripts meant that the swig generation step would fail
whenever there were spaces or special characters in parameters passed to
swig.

The fix for this in CMakeLists is to use the VERBATIM option on all
COMMAND-based custom builders relying on CMake to properly escape each
argument in the generated file.

Within the python swig scripts, the fix is to call subprocess.Popen with
a list of raw argument strings rather than ones that are incorrectly
manually escaped, then passed to a shell subprocess via
subprocess.Popen(' '.join(params)). This also prevents nasty things
happening such as accidental command-injection.

This allows us to have the swig / python executables in paths containing
special chars and spaces, (or on shared storage on Win32, e.g
\\some\path or C:\Program Files\swig\swig.exe).

Chris Bieneman d3199f5ed2 [CMake] Initial support for LLDB.framework
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.

  Target "lldbPluginSymbolFilePDB" has an INTERFACE_LINK_LIBRARIES property.
  This should be preferred as the source of the link interface for this
  library but because CMP0022 is not set CMake is ignoring the property and
  using the link implementation as the link interface instead.

Bruce Mitchener f0248ca545 Add a Post-Build Event on Windows to copy the correct custom Python DLL to the LLDB binaries dir
Summary:
After a developer builds LLDB from source on Windows (assuming they've built it with Python support enabled), they may be somewhat flustered when it fails to launch with a cryptic error.

{F890625}

This happens because Windows can't find python27.dll (or python27_d.dll in case LLDB was built in debug mode). Many developers may have previously installed a release build of Python 2.7 and will not notice anything is amiss when they run a release build of LLDB because Windows will load the python27.dll from one of the system directories or `PATH` (rather than the one that the LLDB build instructions tell them to build). The issue tends to be more pronounced with debug builds of LLDB, since fewer developers probably have python27_d.dll sitting in one of the Windows system directories.

To ensure Windows loads the correct custom built Python DLL when launching LLDB I've added a post-build event that copies the relevant DLL (based on the LLDB build configuration) from `PYTHON_HOME` to the directory in which the LLDB executable is generated.

Zachary Turner 0405d68bb4 Use the debugginess of the python interpreter when symlinking _lldb.pyd.
Previously we would pass an argument to finishSwigWrapperClasses.py which
specified whether this was a debug or a release build.  But sometimes
CMAKE_BUILD_TYPE would not be set to anything, causing this argument
to be empty when passed in.  The only purpose of this argument was to
determine whether or not to append _d to the extension module when
creating the symlink.  This is only necessary when doing a debug
build of LLDB on Windows, which implies a debug interpreter, so we
replace this with a check to see if the running interpreter is a debug
one, and append _d if so.

Zachary Turner f4f8740eb0 [CMake] Change lldbAPI to be a CMake OBJECT library.
An OBJECT library is a special type of CMake library that produces
no archive, has no link interface, and no link inputs.  It is like
a regular archive, just without the physical output.  To link
against an OBJECT library, you reference it in the *source* file
list of a library using the special syntax $<TARGET_OBJECTS:lldbAPI>.
This will cause every object file to be passed to the linker
independently, as opposed to a single archive being passed to the
linker.

This is *extremely* important on Windows.  lldbAPI exports all of the
SB classes using __declspec(dllexport).  Unfortunately for technical
reasons it is not possible (well, extremely difficult) to get the
linker to propagate a __declspec(dllexport) attribute from a symbol
in an object file in an archive to a DLL that links against that
archive.  The solution to this is for the DLL to link the object files
directly.  So lldbAPI must be an OBJECT library.

This fixes an issue that has been present since the duplicated
lldbAPI file lists were removed, which would cause linker failures.

As a side effect, this also makes LLDB_DISABLE_PYTHON=1 work again
on Windows, which was previously totally broken.

Zachary Turner d487bb12d9 [CMake] On Windows, require manual specification of python libs.
Embedding python with MSVC is very finicky, for reasons having
to do with the operating system's CRT, the implementation of
python itself on Windows, and even bugs in CMake.

One side effect of this is that we cannot rely on FindPythonLibs
and FindPythonInterp CMake functions to locate the correct
version of Python.  We must instead manually specify the location
of PYTHON_LIBRARY and PYTHON_INCLUDE_DIR.

As a side effect, this fixes building LLDB in release mode by
specifying -DCMAKE_BUILD_TYPE=Release, which was previously
broken.

Zachary Turner aeda626d80 [CMake] Create a custom target for generating extension module.
Previously we would create the extension module as a post-build
step of creating liblldb.  As part of this process, we created
symlinks and did other stuff.

This had several longstanding issues related to target
dependencies, such as not re-creating the symlink if liblldb.dll
failed to link, or if the build was Ctrl+C'ed from.

Then, the script that creates the symlinks began to grow to
include other things, such as argdumper, and it would try to
create symlinks before it had finished building the targets it
needed to symlink to.

This patches addresses all of these problems by creating an
explicit target for the script to run, and making it have a
dependency on all the targets it needs to create symlinks from/to.

Zachary Turner f3a7da349c Some fixes for linking Python on Windows.
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

Chandler Carruth 875d3bb538 [cmake/multilib] Teach LLDB to respect the multlib LLVM_LIBDIR_SUFFIX
variable (now provided both by the normal parent LLVM CMake files and by
the LLVMConfig.cmake file used by the standalone build).

This allows LLDB to build into and install into correctly suffixed
libdirs. This is especially significant for LLDB because the python
extension building done by CMake directly uses multilib suffixes when
the host OS does, and the host OS will not always look back and forth
between them. As a consequence, before LLVM, Clang, and LLDB (and every
other subproject) had support for using LLVM_LIBDIR_SUFFIX, you couldn't
build or install LLDB on a multilib system with its python extensions
enabled. With this patch (on top of all the others I have submitted
throughout the project), I'm finally able to build and install LLDB on
my system with Python support enabled. I'm also able to actually run the
LLDB test suite, etc. Now, a *huge* number of the tests still fail on my
Linux system, but hey, actually running them and them testing the
debugger is a huge step forward. =D

Chandler Carruth e471e1363e [cmake] Teach the standalone CMake build to find the Python interpreter
the same way the LLVM CMake build does, notably using the proper CMake
module and specifically requesting an older Python version. LLDB relies
pretty heavily on not using Python 3 at this point, and without this
patch it ends up trying to use Python 3 which ends quite badly. =] With
this, I'm able to build LLDB in its standalone mode successfully on
Linux when I have both Python 2.7 and Python 3.3 installed.
