* [CMake] Enhance llvm_update_compile_flags(name sources) to handle ↵NAKAMURA Takumi2014-01-28
| | | | | | | | | | | | | | | | LLVM_REQUIRES_EH and LLVM_REQUIRES_RTTI. 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200301 91177308-0d34-0410-b5e6-96231b3b80d8

* CMake: Provide LLVM_PLUGIN_EXT definitionAlp Toker2014-01-08
| | | | | | | | | | | | | | | This is needed to support the addition of tests for clang loadable plugins. In clang, plugins are built as modules (bundles on OS X) rather than dynamic libraries (dylib) so the build system needs to inform lit of the actual file extension in use, typically '.so' on Unix and '.dll' on Windows. (LLVM itself should probably switch to this scheme to fix PR14903 once and for all.) No change in build output or functionality intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198746 91177308-0d34-0410-b5e6-96231b3b80d8

* EXPORTED_SYMBOL_FILE support for cmakeNico Weber2013-12-28
| | | | | | | | | | | | | | The cmake build didn't support EXPORTED_SYMBOL_FILE. Instead, it had a Windows-only implementation in tools/lto/CMakeLists.txt, a linux-only implementation in tools/gold/CMakeLists.txt, and a darwin-only implementation in tools/clang/tools/libclang/CMakeLists.txt. This attempts to consolidate these one-offs into a single place. Clients can now just set LLVM_EXPORTED_SYMBOL_FILE and things (hopefully) Just Work, like in the make build. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198136 91177308-0d34-0410-b5e6-96231b3b80d8

* CMake : optionaly enable LLVM to be compiled with -std=c++11 (default: off)Arnaud A. de Grandmaison2013-11-26
| | | | | | | | | | In some case, it may be required to build LLVM in C++11 mode, as some the subprojects (like lldb) requires it. This mimics the autoconf behaviour. However, given the discussions on the switch to C++11 of the codebase, this behaviour should evolve to default to C++11 with some checks of the compiler capabilities. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195727 91177308-0d34-0410-b5e6-96231b3b80d8

* CMake: make building with /MT an option instead of always forcing itHans Wennborg2013-11-13
| | | | | | | | | | | | | for release builds. This is a follow-up to r194589. Aaron pointed out that building libraries with /MT and using them in an application that uses a different run-time library can be a bad idea. Move the option to build with /MT behind a CMake option so it can be turned on selectively, such as when building the toolchain installer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194596 91177308-0d34-0410-b5e6-96231b3b80d8

* CMake: set stack size for MSVC in just one placeHans Wennborg2013-10-17
| | | | | | | | | | | After r192904, Reid pointed out he thought we already set the stack size for MSVC. Turns out we did, but it didn't seem to work. This commit sets the stack size in a single place, using CMAKE_EXE_LINKER_FLAGS because that seems to be the way that works best. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192912 91177308-0d34-0410-b5e6-96231b3b80d8

* Tweak the cmake interaction between CMAKE_BUILD_TYPE and LLVM_ENABLE_ASSERTIONS.Duncan Sands2013-07-17
| | | | | | | | | | | | | | | The issue is that CMAKE_BUILD_TYPE=RelWithDebInfo LLVM_ENABLE_ASSERTIONS=ON was not building with assertions enabled. (I was unable to find what in the LLVM source tree was adding -DNDEBUG to the build line in this case, so decided that it must be cmake itself that was adding it - this may depend on the cmake version). The fix treats any mode that is not Debug as being the same as Release for this purpose (previously it was being assumed that cmake would only add -DNDEBUG for Release and not for RelWithDebInfo or MinSizeRel). If other versions of cmake don't add -DNDEBUG for RelWithDebInfo then that's OK: with this change you just get a useless but harmless -UNDEBUG or -DNDEBUG. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186499 91177308-0d34-0410-b5e6-96231b3b80d8
