By default, CMake will set NDEBUG in Rel* builds and leave it off in
debug builds, so we shouldn't need to do anything ourselves.

Before this change, it was possible to a Debug build without assertions
(aka Debug-Asserts in the autoconf system) by configuring with
-DLLVM_ENABLE_ASSERTIONS=OFF, but this configuration isn't very useful.
You can still get the same effect by explicitly adding -DNDEBUG to
CFLAGS.

The option LLVM_ENABLE_SPHINX option enables the "docs-llvm-html",
"docs-llvm-man" targets but does not build them by default. The
following CMake options have been added that control what targets are
made available

SPHINX_OUTPUT_HTML
SPHINX_OUTPUT_MAN

If LLVM_BUILD_DOCS is enabled then the enabled docs-llvm-* targets will
be built by default and if ``make install`` is run then docs-llvm-html
and docs-llvm-man will be installed (tested on Linux only).

The add_sphinx_target function is in its own file so it can be included
by other projects that use Sphinx for their documentation.

It doesn't make sense even with --export-all-symbols.

add_definitions shouldn't really be used for compiler flags, and the variable
LLVM_DEFINITIONS is not appropriately used at the moment, e.g. it's not exported
to LLVMConfig.cmake

[CMake] Enable a bunch of Xcode build settings that correspond to warnings that are for the most part enabled by default either by Clang or -Wall.

I personally build with these settings enabled all the time, and it
is clearer to see the actual warning flags (e.g., -Wuninitialized)
get passed by Xcode rather than seeing -Wno-uninitialized followed
by -Wall (the latter canceling out the former) and figuring out
what is going on.

Xcode will ignore build settings it doesn't understand, so this will
work on possibly older versions of Xcode that don't support all
of these settings.

FIXME: It may be PRIVATE since SO knows its dependent libs.

[CMake] Move LLVMBUILD_LIB_DEPS stuff from add_llvm_library (and LLVm-Config) to llvm_add_library to centralize target_link_libraries.

llvm-svn: 202260

[CMake] Use target_link_libraries(INTERFACE|PRIVATE) on CMake-2.8.12 to increase opportunity for parallel build.

target_link_libraries(INTERFACE) doesn't bring inter-target dependencies in add_library,
although final targets have dependencies to whole dependent libraries.
It makes most libraries can be built in parallel.

target_link_libraries(PRIVATE) is used to shaared library.
Each dependent library is linked to the target.so, and its user will not see its grandchildren.
For example,

  - libclang.so has sufficient libclang*.a(s).
  - c-index-test requires just only libclang.so.

FIXME: lld is tweaked minimally. Adding INTERFACE in each library would be better thing.
llvm-svn: 202241

llvm-svn: 201972

The LLVMSupport library implementation consolidates all dependencies on
system libraries.  Move the logic gathering system libraries out of
'cmake/modules/LLVM-Config.cmake' and into 'lib/Support/CMakeLists.txt'.
Use the target_link_libraries() command there to tell CMake about the
link dependencies of the LLVMSupport implementation.  CMake will
automatically propagate this to all targets that link LLVMSupport
directly or indirectly.

We still need to build knowledge of system library dependencies into
'llvm-config'.  Store the list of libraries needed in a property on
LLVMSupport and teach 'tools/llvm-config/CMakeLists.txt' to retrieve it
from there.

Drop all calls to 'link_system_libs' and 'get_system_libs' from our
CMake code.  Replace their implementations with a warning that explains
the calls are no longer necessary.  Also drop from 'LLVMConfig.cmake'
the HAVE_* and related variables that were published there only to allow
'get_system_libs' to run outside our build process.

[CMake] Introduce "llvm_add_library(SHARED STATIC)" to build both shared lib and static lib simulataneously.

  llvm_add_library(foo SHARED STATIC
    DEPENDS <dependent targets...>
    LINK_LIBS <required libraries...>
    )

It generates both foo (foo.so) and foo_static(foo.a) and both of them depend on DEPENDS and LINK_LIBS.
Then, also obj.foo is generated. obj.foo depends on DEPENDS, but doesn't depend on LINK_LIBS.

llvm-svn: 201854

The module still needs to collect the list of all available libraries
in order to satisfy the 'all' component.  Provide this in the package
configuration file, 'LLVMConfig.cmake', as a LLVM_AVAILABLE_LIBS
variable.  (A variable is scoped better than a global property.)
Since this won't be set for our own build, fall back to looking up the
LLVM_LIBS property to get the value when it is not set.

LLVM library names are now available as logical CMake targets both
to our own build and to application CMake code.  Replace use of
'list(FIND)' with a simple 'if(TARGET)' to determine whether a
library is available.

[CMake] llvm_add_library(MODULE) may use CMAKE_MODULE_LINKER_FLAGS instead of target property LINK_FLAGS.

[CMake] LLVM_PLUGIN_EXT: Use CMAKE_SHARED_LIBRARY_SUFFIX rather than CMAKE_SHARED_MODULE_SUFFIX in llvm tree.

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.

[CMake] llvm_add_library: Add handling of the parameter ADDITIONAL_HEADERS to pass through to process_source.

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.
