* Update the Clang pattern to specify compiler options.Stephen Kelly2013-11-251-2/+7
| | | | | | | | | | In Clang 3.4, the preferred (and new) option pattern is --target=. http://thread.gmane.org/gmane.comp.compilers.clang.devel/29975 http://llvm.org/viewvc/llvm-project?view=revision&revision=184408 Clang 3.4 is not yet released, but there is a release candidate, and there is a dashboard test of Clang trunk.
* Add CMAKE_SYSROOT variable to set --sysroot when cross compiling.Stephen Kelly2013-11-191-0/+1
| | | | | | | | | | As CMAKE_ROOT_FIND_PATH can be a list, a new CMAKE_SYSROOT is introduced, which is never a list. The contents of this variable is passed to supporting compilers as --sysroot. It is also accounted for when processing implicit link directories reported by the compiler, and when generating RPATH information.
* Allow toolchain files to specify an external toolchain.Stephen Kelly2013-11-191-0/+1
| | | | | | | | | Clang can compile code, but uses the gcc tools for other tasks such as linking. The -gcc-toolchain option can be used for that, but generalize so that other compilers can be treated the same. If such a location is specified, use it as a hint for finding the binutils executables.
* Add compiler target compile options.Stephen Kelly2013-11-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | For clang, this allows passing -target <triple> to the compiler, and for qcc, -V<arch> using toolchain files containing something like set(triple arm-linux-gnueabihf) set(CMAKE_C_COMPILER "/usr/bin/clang") set(CMAKE_C_COMPILER_TARGET ${triple}) set(CMAKE_CXX_COMPILER "/usr/bin/clang++") set(CMAKE_CXX_COMPILER_TARGET ${triple}) or set(arch gcc_ntoarmv7le) set(CMAKE_C_COMPILER /opt/qnx650/host/linux/x86/usr/bin/qcc) set(CMAKE_C_COMPILER_TARGET ${arch}) set(CMAKE_CXX_COMPILER /opt/qnx650/host/linux/x86/usr/bin/QCC) set(CMAKE_CXX_COMPILER_TARGET ${arch}) Both clang and qcc are inherently cross compiler( driver)s. When cross-compiling with clang, use the CMAKE_${lang}_COMPILER_TARGET as the _CMAKE_TOOLCHAIN_PREFIX to find the appropriate binutils. When cross-compiling with QNX qcc, use the CMAKE_${lang}_COMPILER_TARGET to set the appropriate _CMAKE_TOOLCHAIN_PREFIX.

| | | | | | | | | | | | | | | | | | | | | | | | Apple distributes their own Clang build with their own version numbers that differ from upstream Clang. Use the __apple_build_version__ symbol to identify the Apple Clang compiler and report the Apple Build Version as the fourth version component in CMAKE_<LANG>_COMPILER_VERSION. Add Compiler/AppleClang-<lang> and Platform/Darwin-AppleClang-<lang> modules that simply include the upstream equivalents. Fix comparisons of CMAKE_<LANG>_COMPILER_ID to Clang in CMake's own source and tests to account for AppleClang.
* | Clang: Support Windows variants for GNU and MSVC (#13035, #14458)Brad King2013-10-042-8/+16
|/ | | | | | | | | | | | | | | | Teach the compiler identification preprocessor tests to report when Clang simulates MSVC, and what version. If not MSVC, assume GNU. Teach compiler information modules Clang-(C|CXX) to recognize when Clang simulates MSVC and skip loading the GNU information. Teach the Windows-MSVC platform information to recognize when it is loaded as the simulated compiler and use that version information instead of the real compiler's (different) version scheme. Add platform modules Windows-Clang-(C|CXX) and support module Windows-Clang to load either Windows-MSVC or Windows-GNU and wrap the corresponding information macros.

* Add a COMPILE_OPTION for a VISIBILITY_INLINES_HIDDEN target property.Stephen Kelly2013-06-022-0/+12

| | | | | | | | | | | | | | According to XL C/C++ V9.0 documentation the default for -qpic/-qnopic is platform-dependent. It won't hurt to add the option on platforms where it is the default, so always add it when we want position independent code.

* Add platform variable for flags specific to shared librariesStephen Kelly2012-06-121-0/+1
| | | | | | Store in CMAKE_${lang}_COMPILE_OPTIONS_DLL flags from CMAKE_SHARED_LIBRARY_${lang}_FLAGS that are truly exclusive to shared libraries.
* Add platform variables for position independent code flagsStephen Kelly2012-06-124-0/+10
| | | | | | | | | | | | | | | | | | | | Store in new platform variables CMAKE_${lang}_COMPILE_OPTIONS_PIC CMAKE_${lang}_COMPILE_OPTIONS_PIE flags for position independent code generation. In almost all cases, this means duplication of the CMAKE_SHARED_LIBRARY_${lang}_FLAGS for the _PIC case and using the assumed pie equivalent for the _PIE case. Note that the GNU compiler has supported -fPIE since 3.4 and that there is no -fPIC on GNU for Windows or Cygwin. There is a possibility that the _PIE variables are not correct. However, as there is no backwards compatibility to be concerned about (as the POSITION_INDEPENDENT_CODE property is not used anywhere yet), the current state suffices.
* Support building shared libraries or modules without soname (#13155)Modestas Vainius2012-04-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a boolean target property NO_SONAME which may be used to disable soname for the specified shared library or module even if the platform supports it. This property should be useful for private shared libraries or various plugins which live in private directories and have not been designed to be found or loaded globally. Replace references to <CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG> and hard-coded -install_name flags with a conditional <SONAME_FLAG> which is expanded to the value of the CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG definition as long as soname supports is enabled for the target in question. Keep expanding CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG in rules in case third party projects still use it. Such projects would not yet use NO_SONAME so the adjacent <TARGET_SONAME> will always be expanded. Make <TARGET_INSTALLNAME_DIR> NO_SONAME aware as well. Since -install_name is soname on OS X, this should not be a problem if this variable is expanded only if soname is enabled. The Ninja generator performs rule variable substitution only once globally per rule to put its own placeholders. Final substitution is performed by ninja at build time. Therefore we cannot conditionally replace the soname placeholders on a per-target basis. Rather than omitting $SONAME from rules.ninja, simply do not write its contents for targets which have NO_SONAME. Since 3 variables are affected by NO_SONAME ($SONAME, $SONAME_FLAG, $INSTALLNAME_DIR), set them only if soname is enabled.

* | XL: Avoid copying archives into shared libraries that link themBrad King2011-04-081-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The XL toolchain supports shared object files stored in archives. Since CMake lists libraries on link lines by full path it is common for a shared library link line to contain the path to an archive file. When linking a shared library the compiler front-end by default runs CreateExportList to construct the list of symbols to be exported. Unfortunately it passes all files found on the command line to the tool so archive and library files get processed along with the object files. The tool returns a list of all symbols in all objects, archives, and libraries on the command line. This causes the linker to copy every object file out of every archive into the shared library whether they are dependencies of the original object files or not. Work around this problem by running CreateExportList ourselves with just the original object files intended for inclusion in the shared library. Then pass the list it produces on the link line to prevent the compiler front-end from constructing its own. This tells the linker to export only the symbols provided by the original source files of the shared library.
* | XL: Consolidate compiler flag informationBrad King2011-04-074-23/+44
