Recently there has been some discussion about how we deal with optional
dependencies in LLDB. The approach in LLVM is to make things work out of
the box. If the dependency isn't there, we move on silently.
That's not true for LLDB. Unless you explicitly disable the dependency
with LLDB_ENABLE_*, you'll get a configuration-time error. The
historical reason for this is that LLDB's dependencies have a much
broader impact, think about Python for example which is required to run
the test suite.
The current approach can be frustrating from a user experience
perspective. Sometimes you just want to ensure LLDB builds with a change
in clang.
This patch changes the optional dependencies (with the exception of
Python) to a new scheme. The LLDB_ENABLE_* now takes three values: On,
Off or Auto, with the latter being the default. On and Off behave the
same as today, forcing the dependency to be enabled or disabled. If the
dependency is set to On but is not found, it results in a configuration
time warning. For Auto we detect if the dependency is there and either
enable or disable it depending on whether it's found.

PS: The reason Python isn't included yet is because it's so pervasive
that I plan on doing that in a separate patch.
This implements a very elementary Lua script interpreter. It supports
running a single command as well as running interactively. It uses
editline if available. It's still missing a bunch of stuff though. Some
things that I intentionally ingored for now are that I/O isn't properly
hooked up (so every print goes to stdout) and the non-editline support
which is not handling a bunch of corner cases. The latter is a matter of
reusing existing code in the Python interpreter.

At least one lldb bot still uses this cmake variable instead of
LLDB_ENABLE_CURSES. Add code to set the default value of the "enable"
variable based on the old value of the "disable" setting.
This should bring those bots back up, until we can update the master to
use the new setting.
This renames LLDB_CONFIG_TERMIOS_SUPPORTED to LLDB_ENABLE_TERMIOS. It
now also uses cmakedefine01 to keep things consistent with out other
optional dependencies. But more importantly it won't silently fail when
you forget to include Config.h.
Centralize the logic to determine what libraries to link against for
curses in the CMake file where it is actually being used. Use
target_include_directories instead of include_directories.
As suggested by Pavel in a code review:

We're checking for support but we're discarding the result. My best
guess is that these warnings were disabled in the past. However, I don't
see a reason to keep it that way.
This fixes the following warning for developers:
Target 'liblldb' was changed to a FRAMEWORK sometime after install(). This
may result in the wrong install DESTINATION. Set the FRAMEWORK property
earlier.
The solution is to pass the FRAMEWORK flag to add_lldb_library and set
the target property before install(). For now liblldb is the only
customer.
Centralize the logic to remove debugserver from
LLVM_DISTRIBUTION_COMPONENTS when LLDB_USE_SYSTEM_DEBUGSERVER is
enabled. Now this happens regardless of whether the tests are enabled.
Summary:
I want to be able to specify which python framework to use for lldb in macos. With python2.7 we could just rely on the MacOS one but python3.7 is not shipped with the OS.
An alternative is to use the one shipped with Xcode but that could be path dependent or maybe the user doesn't have Xcode installed at all.
A definite solution is to just ship a python framework with lldb. To make this possible I added "@loader_path/../../../" to the rpath so it points to the same directory as the LLDB.framework, this way we can just drop any frameworks there.

The swift build system has support for cross-compiling, installing, and
generating symbols for lldb. As the swift symbol-generation step occurs
after installation, we need to disable stripping during the install.
As the name suggests, the LLDB test dependencies only matter to the
different test suites. Therefore they belong in test/CMakeLists.txt
rather than the top-level CMakeLists.txt.
Make it possible to pass a build and install RPATH to
add_lldb_executable instead of having to call lldb_setup_rpaths after
the fact.
This fixes a real issue where setting an install RPATH with
lldb_setup_rpaths would only affect the symroot installation component.
Given that lldb_setup_rpaths sets a target property I would expect this
to be orthogonal to installation components. Regardless, it makes sense
to integrate this functionality in add_lldb_exectable.

Summary:
If the .symtab section is stripped from the binary it might be that
there's a .gnu_debugdata section which contains a smaller .symtab in
order to provide enough information to create a backtrace with function
names or to set and hit a breakpoint on a function name.
This change looks for a .gnu_debugdata section in the ELF object file.
The .gnu_debugdata section contains a xz-compressed ELF file with a
.symtab section inside. Symbols from that compressed .symtab section
are merged with the main object file's .dynsym symbols (if any).
In addition we always load the .dynsym even if there's a .symtab
section.
For example, the Fedora and RHEL operating systems strip their binaries
but keep a .gnu_debugdata section. While gdb already can read this
section, LLDB until this patch couldn't. To test this patch on a
Fedora or RHEL operating system, try to set a breakpoint on the "help"
symbol in the "zip" binary. Before this patch, only GDB can set this
breakpoint; now LLDB also can do so without installing extra debug
symbols:
lldb /usr/bin/zip -b -o "b help" -o "r" -o "bt" -- -h
The above line runs LLDB in batch mode and on the "/usr/bin/zip -h"
target:
(lldb) target create "/usr/bin/zip"
Current executable set to '/usr/bin/zip' (x86_64).
(lldb) settings set -- target.run-args "-h"
Before the program starts, we set a breakpoint on the "help" symbol:
(lldb) b help
Breakpoint 1: where = zip`help, address = 0x00000000004093b0
Once the program is run and has hit the breakpoint we ask for a
backtrace:
(lldb) r
Process 10073 stopped
* thread #1, name = 'zip', stop reason = breakpoint 1.1
frame #0: 0x00000000004093b0 zip`help

frame #3: 0x0000000000408cee zip`_start + 46
In order to support the .gnu_debugdata section, one has to have LZMA
development headers installed. The CMake section, that controls this
part looks for the LZMA headers and enables .gnu_debugdata support by
default if they are found; otherwise or if explicitly requested, the
minidebuginfo support is disabled.
GDB supports the "mini debuginfo" section .gnu_debugdata since v7.6
(2013).

This follows the same pattern as Clang and permits the user to specify
the tablegen to use via `-DLLVM_TABLEGEN=`. This allows for
cross-compiling LLDB for a foreign target (e.g. Windows ARM64 on Windows
X64). The LLVM dependency for LLDB in that case must be a Windows ARM64

When doing a standalone build, without setting LLDB_PATH_TO_LLVM_BUILD

Summary:
We currently have man large arrays containing initializers for our command options.
These tables are tricky maintain as we don't have any good place to check them for consistency and
it's also hard to read (`nullptr, {}, 0` is not very descriptive).
This patch fixes this by letting table gen generate those tables. This way we can have a more readable
syntax for this (especially for all the default arguments) and we can let TableCheck check them
for consistency (e.g. an option with an optional argument can't have `eArgTypeNone`, naming of flags', etc.).
Also refactoring the related data structures can now be done without changing the hundred of option initializers.
For example, this line:
```
{LLDB_OPT_SET_ALL, false, "hide-aliases", 'a', OptionParser::eNoArgument, nullptr, {}, 0, eArgTypeNone, "Hide aliases in the command list."},
```
becomes this:
```
def hide_aliases : Option<"hide-aliases", "a">, Desc<"Hide aliases in the command list.">;
```
For now I just moved a few initializers to the new format to demonstrate the change. I'll slowly migrate the other
option initializers tables in separate patches.

llvm-svn: 365688
Summary:
There's a number of requirements for installing LLDB on macOS that are untypical for LLVM projects: use special install-prefix for LLDB.framework, ship headers and tools as framework resources, patch RPATHs, externalize debug-info to dSYM's and strip binaries with `-ST`. For some of it we could use `llvm_externalize_debuginfo()` in the past and just add special cases. However, this complicates the code for all projects and comes with the major drawback, that it adds all these actions at build-time, i.e. dSYM creation and stripping take a lot of time and don't make sense at build-time.
LLVM's distribution mechanism (https://llvm.org/docs/BuildingADistribution.html) appears to be the natural candidate to install LLDB. Based on D64399 (enable in standalone builds), this patch integrates framework installation with the distribution mechanism and adds custom stripping flags and dSYM creation at install-time. Unlike the abandoned D61952, it leaves build-tree binaries untouched, so there's no side-effects on testing. Potential install-order issues must be handled externally.
Please let me know what you think, while I run a few more tests and add remarks+documentation.

Summary:
This line is unnecessary because add_llvm_executable will handle
linking the correct LLVM libraries for you. LLDB standalone builds are totally
fine without this.
In the best case, having this line here is harmless. In the worst case it can
cause link issues.
If you build lldb-server for android using the standalone build, this line
will cause LLVM_LIBRARY_DIR to be the first place you look for libraries.
This is an issue because if you built libc++, it will try to link against
that one instead of the one from the android NDK. Meanwhile, the LLVM libraries
you're linking against were linked against the libc++ from the NDK.
Ideally, we would take advantage of the AFTER option for link_directories(), but
that was not available in LLDB's minimum supported version of CMake (CMake 3.4.3).

FindPythonInterp and FindPythonLibs do two things, they set some
variables (PYTHON_LIBRARIES, PYTHON_INCLUDE_DIRS) and update the cached
variables (PYTHON_LIBRARY, PYTHON_INCLUDE_DIR) which are also used to
specify a custom python installation.
I believe the canonical way to do this is to use the PYTHON_LIBRARIES
and PYTHON_INCLUDE_DIRS variables instead of the cached ones. However,
since the cached variables are accessible from the cache and GUI, this
is a lot less confusing when you're trying to debug why a variable did
or didn't get the value you expected. Furthermore, as far as I can tell,
the implementation uses the cached variables to set their LIBRARIES/DIRS
counterparts. This is also the reason this works today even though we
mix-and-match.

The package name is LibEdit, so we should use that name in the call to
find_package_handle_standard_args. Failing to do so results in the
standard_args (such as the one telling us whether REQUIRED was used in
the find_package invocation) not being handled.

Summary:
The current install-clang-headers target installs clang's resource
directory headers. This is different from the install-llvm-headers
target, which installs LLVM's API headers. We want to introduce the
corresponding target to clang, and the natural name for that new target
would be install-clang-headers. Rename the existing target to
install-clang-resource-headers to free up the install-clang-headers name
for the new target, following the discussion on cfe-dev [1].
I didn't find any bots on zorg referencing install-clang-headers. I'll
send out another PSA to cfe-dev to accompany this rename.

This was previously scattered between the main CMakeLists.txt file and
LLDBGenerateConfig.cmake and LLDBConfig.cmake. This caused the some of
the code to be executed in incorrect order. Specifically, the check for
el_winsertstr was done before libedit_LIBRARIES was computed, and so it
always failed on the first run.
Moving it the two checks to a central place makes sure this doesn't
happen again and improves the overall readability.

Summary:
Generator expressions are not supported in the `BUILD_RPATH` target property.
`BUILD_RPATH` is only supported in 3.8+ https://cliutils.gitlab.io/modern-cmake/chapters/intro/newcmake.html
`LLDB_FRAMEWORK_INSTALL_DIR` should not overwrite, but rather add an install RPATH (and it should be the first)

Restore the previous behavior of using install directories for
LLVM_MAIN_INCLUDE_DIR, LLVM_LIBRARY_DIR and LLVM_BINARY_DIR. The update
from llvm-config to CMake has changed the values of those values to use
LLVM_BUILD_* which is plain wrong and breaks stand-alone builds.
Instead, use the CMake counterparts of the values returned
by llvm-config.

Summary:
D57334 added entitlements support in `add_llvm_library()` so we can use it for library targets in LLDB.
Additionally this patch fixes the way that the entitlements argument is passed on from `add_lldb_executable()` to `add_llvm_executable()`. We still need the explicit parsing and passing on of single- and multi-value arguments as long as we are on CMake < 3.7 (due to bug https://gitlab.kitware.com/cmake/cmake/merge_requests/133).

Refactor the get_llvm_lit_path() logic to respect LLVM_EXTERNAL_LIT,
and require the fallback to be defined explicitly
as LLVM_DEFAULT_EXTERNAL_LIT. This fixes building libcxx standalone
after r346888.
The old logic was using LLVM_EXTERNAL_LIT both as user-defined cache
variable and an optional pre-definition of default value from caller
(e.g. libcxx). It included a hack to make this work by assigning
the value back and forth but it was fragile and stopped working
in libcxx.
The new logic is simpler and more transparent. Default value is
provided in a separate variable, and used only when user-specified
variable is empty (i.e. not overriden).

Summary:
When cross-compiling LLDB, we want to use llvm-tblgen built for the
host, not the target.
