FIXME: llvm/test may be aware of LLVM_PLUGIN_EXT, like as clang/test does.
FIXME: CMAKE_*_SUFFIX may be set in HandleLLVMOptions if those variables could be writable, rather than to set one as target properties.

I was insightless then about unknown optional parameters.
(Consider that LINK_LIBS foo bar ADDITIONAL_HEADERS qux quux)

This macro depends on several variables to be set in the calling
context. Check them and report an error if they are not set.
Without this, custom commands may be silently specified that
will fail at build time.

- MODULE;SHARED;STATIC
STATIC by default w/o BUILD_SHARED_LIBS.
SHARED by default w/ BUILD_SHARED_LIBS.
- OUTPUT_NAME name
Corresponds to OUTPUT_NAME in target properties.
- DEPENDS targets...
Same semantics as add_dependencies().
- LINK_COMPONENTS components...
Same as the variable LLVM_LINK_COMPONENTS.
- LINK_LIBS lib_targets...
Same semantics as target_link_libraries().
- ADDITIONAL_HEADERS (implemented in LLVMProcessSources)
May specify header files for IDE generators.
I suggest llvm_add_library() may be used for inter-project add_library stuff
and also suggest add_***_library() may be used project-specific.
Please be patient that llvm_add_library might be ambiguous against add_llvm_library.

I am sure it'd not be required any more.
In trunk, all of tablegen's users depend on ${TABLEGEN_OUTPUT} as not file dependency but inter-target dependency.

CMake's target_link_libraries() will manage dependencies with Brad's LLVMConfig improvements.
Configuration time may be reduced by a few seconds.

You can't put a comment in the middle of a command like this. This is
invalid shell syntax and breaks the build.

Teach the Makefile build system to generate and install CMake modules
LLVMConfig.cmake and LLVMConfigVersion.cmake so that applications that
build with CMake can use 'find_package(LLVM)' even when LLVM is not
built with CMake. These modules tell such applications about available
LLVM libraries and their dependencies.
Run llvm-config to generate the list of libraries and use the results of
llvm-build to generate the library dependencies. Use sed to perform
substitutions in the LLVMConfig.cmake.in and LLVMConfigVersion.cmake.in
sources that our CMake build system uses.
Teach the Makefile build system to generate the LLVMExports.cmake file
with content similar to that produced by the CMake install(EXPORT)
command. Extend llvm-build with an option to generate the library
dependencies fragment for this file.

Teach each package configuration file to load the LLVMExports file for
its corresponding tree. This will allow application CMake code to use
logical library and executable target names from LLVM as if they were in
our own build process (e.g. LLVMSupport). CMake will have enough
information to propagate LLVM library link dependencies automatically
while configuring applications.

Record every logical target that we install with install(TARGETS) in a
global LLVM_EXPORTS property. Then use the export(TARGETS) command to
provide a "LLVMExports.cmake" file that exports logical targets for
import into applications directly from our build tree.
The "LLVMExports.cmake" file is not meant for direct inclusion by
application code but should be included by "LLVMConfig.cmake" in a
future change.

Use the install(TARGETS) command EXPORT option for every library and

Create separate package configuration files "LLVMConfig.cmake" for the
LLVM build and install trees so that each can have information specific
to its tree. Configure each with the corresponding include, lib, and
cmake directories. Include the "LLVM-Config" API modules directly from
the configured cmake modules directory.
In the install tree, compute the installation prefix relative to the
file location. In the build tree, provide information specific to the
build tree for use by tools like Clang that can build externally against
the LLVM build tree. Prefix such values in "LLVM_BUILD_" and comment
them as such.

Do not modify this value on the application's behalf and just ensure API
modules are always available next to the LLVMConfig module. This is
already the case in the install tree so use file(COPY) to make it so in
the build tree. Include the LLVM-Config API module from next to the
LLVMConfig location.

CMake won't expand the dependency graph for us if the dependencies are in
another project, which leads to link errors in the standalone build.
This is a refinement of r200765.
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200812 91177308-0d34-0410-b5e6-96231b3b80d8
r200744 moved this into cmake/config-ix.cmake, so that it would happen very
early in the build process. However, standalone builds of Clang and other
external projects never include this file (which is correct).
Now, -stdlib=libc++ and the LLVM_COMPILER_IS_GCC_COMPATIBLE option are
both set in a new include file, HandleLLVMStdlib, which is included by
both config-ix.cmake and HandleLLVMOptions.cmake. This preserves existing
behavior for projects relying on HandleLLVMOptions and still does the
right thing for builds of LLVM itself.

In trunk, every users assume add_llvm_loadable_module as "loadable module" and no one sets neither SHARED, ... nor also MODULE!
Unfortunately, all loadable modules were linked as not "MODULE" but "SHARED".
If this change caused any regressions, I wish guys to fix it properly. ;)

If LLVM_ENABLE_LIBCXX is specified, we should append -stdlib=libc++ to build
flags as early as possible, in particular, before we check for header presence
(as -stdlib=libc++ modifies header lookup rules). Otherwise we can find a header
at configure time (w/o -stdlib=libc++) but fail to find it at build time
(with -stdlib=libc++). See PR18569 for more details.

It missed include/llvm/Target. Could I avoid GLOB_RECURSE anyways? :(
FYI, I intended to prune ${LLVM_MAIN_INCLUDE_DIR} in TableGen.cmake in r200150.

This will disable -ffunction-sections in older versions of Clang where it
breaks build of sanitizer runtime library.

LLVM_REQUIRES_EH implies LLVM_REQUIRES_RTTI. It is as same behavior as Makefile.rule's.
llvm/examples/ExceptionDemo is affected. (It was built with -fno-rtti.)
For MSVC, Remove flags like "/EHsc /GR" in HandleLLVMOptions, or CL.EXE complains with flags like "/GR /GR-".
llvm_update_compile_flags() updates source file property if the target contains *.c.
COMPILE_FLAGS in target properties affects both C++ and C!
LLVM_NO_RTTI is deprecated. It was introduced by me and was my mistake.

With this tweaks, also unittests are compiled with -ffunction-sections.
It's hard to control contextual CMAKE_CXX_FLAGS. We should get rid of twiddling it as possible.

ADDITIONAL_HEADERS is intended to add header files for IDEs as hint.

add_llvm_library(LLVMSupport
Host.cpp
ADDITIONAL_HEADERS
Unix/Host.inc
Windows/Host.inc

In LLVM build tree, they points corresponding INTDIR.
In Clang standalone tree, they points external dir (llvm-config's --bindir and --libdir).
