This patch abstracts the generation of Config.h and creates a dummy project entry point to allow generation of LLDB's Config header without performing a full CMake configuration.
This will enable the Xcode project to generate LLDB's Config header.

This support was landed in r300579, and reverted in r300669 due to failures on the bots.
The failures were caused by sockets not being properly closed, and this updated version of the patches should resolve that.
Summary from the original change:
This patch adds IPv6 support to LLDB/Host's TCP socket implementation. Supporting IPv6 involved a few significant changes to the implementation of the socket layers, and I have performed some significant code cleanup along the way.
This patch changes the Socket constructors for all types of sockets to not create sockets until first use. This is required for IPv6 support because the socket type will vary based on the address you are connecting to. This also has the benefit of removing code that could have errors from the Socket subclass constructors (which seems like a win to me).
The patch also slightly changes the API and behaviors of the Listen/Accept pattern. Previously both Listen and Accept calls took an address specified as a string. Now only listen does. This change was made because the Listen call can result in opening more than one socket. In order to support listening for both IPv4 and IPv6 connections we need to open one AF_INET socket and one AF_INET6 socket. During the listen call we construct a map of file descriptors to addrin structures which represent the allowable incoming connection address. This map removes the need for taking an address into the Accept call.
This does have a change in functionality. Previously you could Listen for connections based on one address, and Accept connections from a different address. This is no longer supported. I could not find anywhere in LLDB where we actually used the APIs in that way. The new API does still support AnyAddr for allowing incoming connections from any address.
The Listen implementation is implemented using kqueue on FreeBSD and Darwin, WSAPoll on Windows and poll(2) everywhere else.

The break the linux bots (and probably any other machine which would
run the test suite in a massively parallel way). The problem is that it
can happen that we only successfully create an IPv6 listening socket
(because the relevant IPv4 port is used by another process) and then the
connecting side attempts to connect to the IPv4 port and fails.
It's not very obvious how to fix this problem, so I am reverting this
until we come up with a solution.

Summary:
This patch removes the hand maintained config files in favor of auto-generating the config file. We will still need to maintain the defines for the Xcode builds on Mac, but all CMake builds use the generated header instead.
This will enable finer grained platform support tests and enable supporting LLDB on more platforms with less manual maintenance.
I have only tested this patch on Darwin, and any help testing it out on other platforms would be greatly appreciated. I've probably messed something up somewhere.

This patch does two things. First it updates all the ABI plugins with accurate dependencies, and second it adds a tracking mechanism for add_lldb_library to denote plugin libraries, allowing us to build up a list of all the configured plugins.
This list of generated plugins will be used during generating liblldb so that we can link all the plugins into the library.
If this patch looks good I will update all the other plugins in subsequent patches.

Instead I rely, on __ANDROID__, which is set by the compiler.
I haven't yet removed the cmake variable with the same name, as we will need to
do something completely different there -- NDK toolchain defines
CMAKE_SYSTEM_NAME to Android, while our current one pretends it's linux.

The Windows process plugin was broken up into multiple pieces a while back in
order to share code between debugging live processes and minidumps
(postmortem) debugging. The minidump portion was replaced by a cross-platform
solution. This left the plugin split into a formerly "common" base classes and
the derived classes for live debugging. This extra layer made the code harder
to understand and work with.
This patch simplifies these class hierarchies by rolling the live debugging
concrete classes up to the base classes. Last week I posted my intent to make
this change to lldb-dev, and I didn't hear any objections.
This involved moving code and changing references to classes like
ProcessWindowsLive to ProcessWindows. It still builds for both 32- and 64-bit,
and the tests still pass on 32-bit. (Tests on 64-bit weren't passing before
this refactor for unrelated reasons.)

With the cross-platform minidump plugin working, the Windows-specific one is no longer needed. This eliminates the unnecessary code.
This does not eliminate the Windows-specific tests, as they hit a few cases the general tests don't. (The Windows-specific tests are currently passing.) I'll look into a separate patch to make sure we're not doing too much duplicate testing.
After that I might do a little re-org in the Windows plugin, as there was some factoring there (Common & Live) that probably isn't necessary anymore.

Since Xcode can't seem to handle quotes in preprocessor definitions, I've changed the build to assume that the define is unquoted. This should fix the failing Darwin bots.
llvm-svn: 286504
Summary:
This change unifies and simplifies the code paths between the Darwin and non-Darwin code to print the LLDB version information.
It also introduces a new variable in CMake LLDB_VERSION_STRING which can be used to specify custom version information. On Darwin this value is implicitly set based on the resource/LLDB-Info.plist file.
With the LLDB_VERSION_STRING variable set to lldb-360.99.0, the -version output is:
> ./bin/lldb -version
lldb version 4.0.0 (lldb-360.99.0)

Summary:
The dependencies of our libraries (only liblldb, really) we marked as public, which caused all
their dependencies to be repeated when linking any executables to them. This is a problem because
then all the .a files could end up being linked twice, once to liblldb and once
again to to the executable linking against liblldb (lldb, lldb-mi). As it turns out,
our build actually depends on this behavior:
- on windows, lldb does not have getopt, so it pulls it from inside liblldb, even
though getopt is not a part of the exported interface of liblldb (maybe some of
the bsd variants have this problem as well)
- lldb-mi uses llvm, which again is not exported by liblldb
This change does not actually fix these problems (that is going to be a hard
one), but it does make them explicit by moving this magic from add_lldb_library
to the places the executable targets are defined. That way, I can link the
additional .a files only on targets that really need it, and the other targets
can build cleanly and make sure we don't regress further. It also fixes the
LLVM_LINK_LLVM_DYLIB build on linux.

This code was adding an explicit dependency on libclang because lldb needs clang headers, changing this to instead depend on the clang tablegen targets means we don't have to depend on building the clang bits in libclang that lldb doesn't need.
Note this is still a bit of a hack because we're adding the dependency to all lldb libraries, instead of just the ones that need it.
llvm-svn: 282196
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.

Summary:
Previously the builting demangler was on for platforms that explicitly set a flag by modifying
Mangled.cpp (windows, freebsd). The Xcode build always used builtin demangler by passing a
compiler flag. This adds a cmake flag (defaulting to ON) to configure the demangling library used
at build time. The flag is only available on non-windows platforms as there the system demangler
is not present (in the form we're trying to use it, at least).
The impact of this change is:
- linux: switches to the builtin demangler
- freebsd, windows: NFC (I hope)
- netbsd: switches to the builtin demangler
- osx cmake build: switches to the builtin demangler (matching the XCode build)
The main motivation for this is the cross-platform case, where it should bring more consistency
by removing the dependency on the host demangler (which can be completely unrelated to the debug
target).
