Chandler Carruth 25eacf7e77 [C++11] Switch the CMake option from LLVM_ENABLE_CXX11 (default on) to
LLVM_ENABLE_CXX1Y (default *off*). =D C++98 is dead. Long live C++11.

I don't exactly recommend using C++1y just yet though...

NAKAMURA Takumi 955d27a4ce [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.

NAKAMURA Takumi af2c1130ee Simplify linking to system libraries
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.

NAKAMURA Takumi e3408ab565 [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.

NAKAMURA Takumi 12fedb0efd Teach LLVM-Config to use logical target names (2/2)
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.

NAKAMURA Takumi e7038dfeaa [CMake] Introduce llvm_add_library().
- 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.

NAKAMURA Takumi 01e3c64f11 Provide CMake package modules in install tree
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.

NAKAMURA Takumi 363e85a143 Load exported lib and exe targets from LLVMConfig
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.

NAKAMURA Takumi 43d6384c38 Provide LLVMConfig in both build and install tree
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.

Todd Fiala 4ccfe392ed Fix configure to find arc4random via header files.
ISSUE:

On Ubuntu 12.04 LTS, arc4random is provided by libbsd.so, which is a
transitive dependency of libedit. If a system had libedit on it that
was implemented in terms of libbsd.so, then the arc4random test,
previously implemented as a linker test, would succeed with -ledit.
However, on Ubuntu this would also require a #include <bsd/stdlib.h>.
This caused a build breakage on configure-based Ubuntu 12.04 with
libedit installed.

FIX:

This fix changes configure to test for arc4random by searching for it
in the standard header files. On Ubuntu 12.04, this test now properly
fails to find arc4random as it is not defined in the default header
locations. It also tweaks the #define names to match the output of the
header check command, which is slightly different than the linker
function check #defines.

I tested the following scenarios:

(1) Ubuntu 12.04 without the libedit package [did not find arc4random,
as expected]

(2) Ubuntu 12.04 with libedit package [properly did not find
arc4random, as expected]

(3) Ubuntu 12.04 with most recent libedit, custom built, and not
dependent on libbsd.so [properly did not find arc4random, as
expected].

(4) FreeBSD 10.0B1 [properly found arc4random, as expected]

Jordan Rose 5fe0f6588e [CMake] Deliberately get all LLVM library dependencies for standalone builds.

Jordan Rose 31c5b7b696 [CMake] Move -stdlib=libc++ handling into its own file.
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.
