* [CMake] Introduce llvm_add_library().NAKAMURA Takumi2014-02-10
| | | | | | | | | | | | | | | | | | | | | | | - 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201072 91177308-0d34-0410-b5e6-96231b3b80d8

* Provide CMake package modules in install treeNAKAMURA Takumi2014-02-09
| | | | | | | | | | | | | | | | | | | | | | 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.

* Load exported lib and exe targets from LLVMConfigNAKAMURA Takumi2014-02-09
| | | | | | | | | | | | | 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.

* Export lib and exe build target names from build treeNAKAMURA Takumi2014-02-09
| | | | | | | | | | | | | | | 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.

* Provide LLVMConfig in both build and install treeNAKAMURA Takumi2014-02-09
| | | | | | | | | | | | | | | | | | 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. Contributed by Brad King. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201048 91177308-0d34-0410-b5e6-96231b3b80d8
* Teach LLVMConfig to avoid modifying CMAKE_MODULE_PATHNAKAMURA Takumi2014-02-09
| | | | | | | | | | | | 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.

* Fix configure to find arc4random via header files.Todd Fiala2014-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200819 91177308-0d34-0410-b5e6-96231b3b80d8
* [CMake] Deliberately get all LLVM library dependencies for standalone builds.Jordan Rose2014-02-05
| | | | | | | | 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
* [CMake] Move -stdlib=libc++ handling into its own file.Jordan Rose2014-02-05
| | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200811 91177308-0d34-0410-b5e6-96231b3b80d8

* Introduce line editor library.Peter Collingbourne2014-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | This library will be used by clang-query. I can imagine LLDB becoming another client of this library, so I think LLVM is a sensible place for it to live. It wraps libedit, and adds tab completion support. The code is loosely based on the line editor bits in LLDB, with a few improvements: - Polymorphism for retrieving the list of tab completions, based on the concept pattern from the new pass manager. - Tab completion doesn't corrupt terminal output if the input covers multiple lines. Unfortunately this can only be done in a truly horrible way, as far as I can tell. But since the alternative is to implement our own line editor (which I don't think LLVM should be in the business of doing, at least for now) I think it may be acceptable. - Includes a fallback for the case where the user doesn't have libedit installed. Note that this uses C stdio, mainly because libedit also uses C stdio.
