* Prospective -fsanitize=memory build fix following r212586Alp Toker2014-07-091-3/+3
| | | | | | | | | | | This -f group flag appears to influence linker flags, breaking the usual rules and causing CMake's link invocation to fail during feature detection due to missing link dependencies (msan_*). Let's forcibly add it for now to get things the way they were before feature detection started working. llvm-svn: 212590
* CMake: make __DATE__, __TIME__ etc. macro usage an errorAlp Toker2014-07-091-0/+3
| | | | | | | | | | | | | | | | When LLVM_ENABLE_TIMESTAMPS has been disabled we can prevent the preprocessor from embedding dates, times and file timestamps. There are a few motivations for this: 1) Validate the recent CMake feature detection bugfix from LLVM r212586 with a flag that's not actually available everywhere. 2) Dogfood clang's new -Wdate-time warning from r210511 when bootstrapping. 3) Encourage reproducible builds. llvm-svn: 212587
* CMake: fix compiler feature detectionAlp Toker2014-07-091-36/+27
| | | | | | | | | | | | | | | | | | | | add_flag_if_supported() and add_flag_or_print_warning() were effectively no-ops, just returning the value of the first result (usually '-fno-omit-frame-pointer') for all subsequent checks for different flags. Due to the way CMake caches feature detection results, we need to provide symbolic variable names which will persist the cached results. This commit fixes feature detection using these two macros. The feature checks now run and get stored correctly, and the correct output can be observed in configure logs: -- Performing Test C_SUPPORTS_FPIC -- Performing Test C_SUPPORTS_FPIC - Success -- Performing Test CXX_SUPPORTS_FPIC -- Performing Test CXX_SUPPORTS_FPIC - Success llvm-svn: 212586
* [CMake] Introduce LLVM_ENABLE_PLUGINS as an internal option. ↵NAKAMURA Takumi2014-07-042-8/+17
| | | | | | | | | | | BUILD_SHARED_LIBS may not control enable/disable plugins. FIXME: Make this configurable. FIXME: "ENABLE_SHARED" doesn't make sense, since it is used just for plugins. We may rename it. I introduced config.enable_shared in r120273. llvm-svn: 212315
* [CMake] Introduce LLVM_SHLIB_OUTPUT_INTDIR.NAKAMURA Takumi2014-07-041-1/+1
| | | | | | For now, its user is configure_lit_site_cfg(). llvm-svn: 212314

* cmake: Don't do anything for LLVM_ENABLE_ASSERTIONS=OFFReid Kleckner2014-06-271-6/+0
| | | | | | | | | | | | | | | | | 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. Differential Revision: http://reviews.llvm.org/D4257 Patch by Janusz Sobczak! llvm-svn: 211919

* Disable -Wcomment when building with GCC.Evgeniy Stepanov2014-05-061-0/+11

* Added Sphinx documentation generation to CMake build system.Reid Kleckner2014-04-182-0/+79
| | | | | | | | | | | | | | | | | | | | | 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. Patch by Daniel Liew <daniel.liew@imperial.ac.uk>! llvm-svn: 206655

* [CMake] Put -Werror to CMAKE_CXX_FLAGS instead of using add_llvm_definitions()Alexey Samsonov2014-03-131-3/+1
| | | | | | | | 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 llvm-svn: 203792
* [CMake] Enable a bunch of Xcode build settings that correspond to warnings ↵Ted Kremenek2014-03-131-0/+23
| | | | | | | | | | | | | | | | 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. llvm-svn: 203760

* [CMake] Use target_link_libraries(INTERFACE|PRIVATE) on CMake-2.8.12 to ↵NAKAMURA Takumi2014-02-262-3/+16
| | | | | | | | | | | | | | | | | | 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

* Simplify linking to system librariesNAKAMURA Takumi2014-02-233-47/+7
| | | | | | | | | | | | | | | | | | | | | | | | | 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 ↵NAKAMURA Takumi2014-02-211-2/+36
| | | | | | | | | | | | | | 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
* Teach LLVM-Config to use logical target names (2/2)NAKAMURA Takumi2014-02-214-8/+11
| | | | | | | | | | | | | 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. Contributed by Brad King. llvm-svn: 201853
* Teach LLVM-Config to use logical target names (1/2)NAKAMURA Takumi2014-02-211-15/+7
| | | | | | | | | | | 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. Contributed by Brad King. llvm-svn: 201852

* Teach tablegen() macro to check needed variablesNAKAMURA Takumi2014-02-121-0/+11

| | | | | | | | | | | | | | | | | | | | | | | - 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. llvm-svn: 201072
