* Update links to gitlab.kitware.com repos to add `-/`Brad King2020-05-261-1/+1
| | | | | | GitLab now uses a `/-/` component between the `group/project` part of the URL and the `{issues,merge_requests,tree}` part so that it can support `group/subgroup/project` with arbitrary depth.

* clang: Work around toolchain file use of internal CMake variablesBrad King2019-08-051-0/+16
| | | | | | | | | | | | Since commit d44c0db0b2 (clang: setup correct configuration in gnu mode, 2019-02-20, v3.15.0-rc1~41^2~5) our Clang compiler information modules need the `CMAKE_<LANG>_COMPILER_FRONTEND_VARIANT` variable that we compute during compiler detection. However, some existing toolchain files set our internal `CMAKE_<LANG>_COMPILER_ID_RUN` variables and block that detection, but do not set the new frontend variant variable. Help them out by setting `CMAKE_<LANG>_COMPILER_FRONTEND_VARIANT` anyway. Fixes: #19515, #19539

| * clang: introduce CMAKE_<lang>_COMPILER_FRONTEND_VARIANTZsolt Parragi2019-05-171-1/+0
| | | | | | | | | | | | | | | | This variable is set to GNU on Windows when clang.exe ar clang++.exe is used, and set to MSVC for clang-cl.exe. CMAKE_<lang>_SIMULATE_ID is set to MSVC in both cases, as clang defaults to -fms-compatibility for all command lines on windows.

* Xcode: Detect architecture(s) using ARCHS instead of CURRENT_ARCHBrad King2018-06-181-3/+3
| | | | | | | | | Xcode 10 no longer populates `CURRENT_ARCH` with the current architecture in shell scripts and instead uses `undefined_arch`. Instead we must use `ARCHS`. It lists all architectures separated by spaces. Fixes: #18085
* CMakeFindBinUtils: Improve switch between MSVC- and GNU-like toolsBrad King2017-11-281-1/+1
| | | | | | | | The switch was not considering some languages, such as `ASM`. Instead of memorizing the list of languages in the condition, use a language specified by the includer. Fixes: #17510
* Clang: Diagnose unsupported GNU-like clang targeting MSVC ABIBrad King2017-10-101-0/+1
| | | | | | | | | | The LLVM/Clang installer on Windows provides a `LLVM/bin` directory containing `clang.exe` and `clang++.exe` command-line tools that have a GNU-like command-line but target the MSVC ABI (instead of MinGW). We do not support this combination, so diagnose and reject it explicitly. Tell users what to do to use the `clang-cl.exe` tool instead. Issue: #16439
* Add a CMAKE_<LANG>_COMPILER_ARCHITECTURE_ID variableNorbert Lange2017-06-291-0/+7
| | | | | | | | | | Compilers such as MSVC and IAR may have variants that target different architectures. We have been using a `MSVC_<LANG>_ARCHITECTURE_ID` variable to hold this information for MSVC. Add an alternative with a more general name (later we can port MSVC to it too). This additional information may be needed to generate proper invocations of the compiler based on its architecture variant.
* Xcode: Detect CURRENT_ARCH for use by generatorBrad King2017-03-311-0/+5
| | | | | | | During compiler identification, extract the Xcode `CURRENT_ARCH` value and save it for later use by the Xcode generator in an internal compiler information variable. This will be useful to know the locations of object files when only one architecture is built.

* Simplify CMake per-source license noticesBrad King2016-09-271-12/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Per-source copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong. Precise contributor information is already maintained automatically by the version control tool. Ultimately it is the receiver of a file who is responsible for determining its licensing status, and per-source notices are merely a convenience. Therefore it is simpler and more accurate for each source to have a generic notice of the license name and references to more detailed information on copyright holders and full license terms. Our `Copyright.txt` file now contains a list of Contributors whose names appeared source-level copyright notices. It also references version control history for more precise information. Therefore we no longer need to spell out the list of Contributors in each source file notice. Replace CMake per-source copyright/license notice headers with a short description of the license and links to `Copyright.txt` and online information available from "https://cmake.org/licensing". The online URL also handles cases of modules being copied out of our source into other projects, so we can drop our notices about replacing links with full license text. Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority of the replacements mechanically. Manually fix up shebang lines and trailing newlines in a few files. Manually update the notices in a few files that the script does not handle.

* Modules: Rename internal platform-specific compiler determination modulesBrad King2016-06-021-0/+1
| | | | | | | Rename Modules/Platform/<os>-<lang>.cmake files to Modules/Platform/<os>-Determine-<lang>.cmake to clarify their role. For compatibility with user-provided modules, load the old names if they exist.

* Replace http://www.cmake.org URLs with https://cmake.orgBrad King2015-09-251-1/+1
| | | | | | | The latter is now the preferred URL for visiting cmake.org with a browser. Convert using the shell code: git ls-files -z | xargs -0 sed -i 's|http://www\.cmake|https://cmake|g'
* Ninja: Detect MSVC /showIncludes prefix with compiler flags (#15596)Brad King2015-09-181-1/+0
| | | | | | | | Move detection over to the compiler id logic where we have already constructed the list of compiler flags from ARG1 and CMAKE_<LANG>_FLAGS. Pass the flags when we execute "cl" with "/showIncludes". Also pass "/c" because we only need to compile, not link. Check the compiler process exit code before trusting its output.

* | CMakeDetermineCompilerId: Use per-language regex to match Xcode compiler toolBrad King2015-06-301-0/+8
| | | | | | | | | | | | Move the Ld invocation match expression from CMakeDetermineCompilerId into CMakeDetermine{C,CXX,Fortran}Compiler so that it can be specified on a per-language basis.
* | CMakeDetermineCompilerId: Optionally try some flags before no flagsBrad King2015-06-181-0/+1
|/ | | | | | | | Teach CMAKE_DETERMINE_COMPILER_ID to optionally try detecting the compiler id using some given flags before trying to detect it with no special flags. This will be useful for Fortran detection to distinguish some compilers that use the preprocessors of others but have no macro of their own by getting verbose output.
* Avoid if() quoted auto-dereferenceBen Boeckel2014-10-201-4/+4
| | | | | | | When testing CMAKE_<LANG>_COMPILER_ID values, do not explicitly dereference or quote the variable. We want if() to auto-dereference the variable and not its value. Also replace MATCHES with STREQUAL where equivalent.

| * Fix finding binutils when cross-compiling with ClangBrad King2014-09-051-1/+3
| | | | | | | | | | | | | | | | | | Since commit v3.0.0-rc1~342^2~2 (Add compiler target compile options, 2013-05-19) we use CMAKE_<LANG>_COMPILER_TARGET as the binutils prefix when cross-compiling with Clang. Fix the implementation to use the compiler target as the prefix only when it is set. Otherwise toolchain files not using CMAKE_<LANG>_COMPILER_TARGET cause the logic to use a prefix of just "-" and of course cannot find "-ar" or "-ld".

* Xcode: Convert forced CMAKE_<LANG>_COMPILER to full path if possibleBrad King2014-03-101-0/+1
| | | | | | | During cross-compiling the toolchain file may use CMakeForceCompiler to force a compiler setting. When using the Xcode generator try to convert it to a full path by searching the PATH as is done for the Makefile generators.

* Add compiler target compile options.Stephen Kelly2013-11-191-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * Make platform information files specific to the CMake versionBrad King2012-08-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At the top of a build tree we configure inside the CMakeFiles directory files such as "CMakeSystem.cmake" and "CMake<lang>Compiler.cmake" to save information detected about the system and compilers in use. The method of detection and the exact results store varies across CMake versions as things improve. This leads to problems when loading files configured by a different version of CMake. Previously we ignored such existing files only if the major.minor part of the CMake version component changed, and depended on the CMakeCache.txt to tell us the last version of CMake that wrote the files. This led to problems if the user deletes the CMakeCache.txt or we add required information to the files in a patch-level release of CMake (still a "feature point" release by modern CMake versioning convention). Ensure that we always have version-consistent platform information files by storing them in a subdirectory named with the CMake version. Every version of CMake will do its own system and compiler identification checks even when a build tree has already been configured by another version of CMake. Stored results will not clobber those from other versions of CMake which may be run again on the same tree in the future. Loaded results will match what the system and language modules expect. Rename the undocumented variable CMAKE_PLATFORM_ROOT_BIN to CMAKE_PLATFORM_INFO_DIR to clarify its purpose. The new variable points at the version-specific directory while the old variable did not.
