| | | | | If the `CMAKE_CXX<STANDARD>_COMPILER_IMPORT_STD_NOT_FOUND_MESSAGE` variable is set, include its value in the error message.
* Add CMAKE_<LANG>_STANDARD_LATEST variablesTyler2024-04-3048-50/+274
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a variable to indicate the latest standard known to be supported for each language: * `CMAKE_C_STANDARD_LATEST` * `CMAKE_CXX_STANDARD_LATEST` * `CMAKE_CUDA_STANDARD_LATEST` * `CMAKE_HIP_STANDARD_LATEST` * `CMAKE_OBJC_STANDARD_LATEST` * `CMAKE_OBJCXX_STANDARD_LATEST` These variables, more generally referred to as `CMAKE_<LANG>_STANDARD_LATEST`, are assigned an integer value which represents the minimum between the latest version of the associated language standard supported by the current compiler and the latest version supported by CMake. Add documentation for these variables in a new page called `CMAKE_<LANG>_STANDARD_LATEST` was added under the "Variables for Languages" section of the `cmake-variables(7)` page. Update each compiler-specific CMake script under `${CMAKE_ROOT}\Modules\Compiler` to manually define the relevant `CMAKE_<LANG>_STANDARD_LATEST` variable as necessary. This will require updating and maintaining as newer compiler versions become recognized by CMake. Closes: #25717
* AppleClang: Fix Objective C 23 support detectionTyler Nichols2024-04-301-1/+1
| | | | | | | Set the requirement for Objective C 23 support for AppleClang to `11.0.3` in `${CMAKE_ROOT}\Modules\Compiler\AppleClang-OBJC.cmake`. This is consistent with the requirement for C 23 support as indicated in `${CMAKE_ROOT}\Modules\Compiler\AppleClang-C.cmake`.
* Modules: Fix ARMClang and TIClang language standard compile optionsTyler Nichols2024-04-303-0/+27
| | | | | | | | | | | | | | | | Unset irrelevant compile option variables in the following scripts: * `${CMAKE_ROOT}\Modules\Compiler\ARMClang-C.cmake` * `${CMAKE_ROOT}\Modules\Compiler\TIClang-C.cmake` * `${CMAKE_ROOT}\Modules\Compiler\TIClang-CXX.cmake` These scripts all include either `${CMAKE_ROOT}\Modules\Compiler\Clang-C.cmake` or `${CMAKE_ROOT}\Modules\Compiler\Clang-CXX.cmake`, and those scripts will set various compile option variables based on what the standard version of Clang supports. However, these do not necessarily apply to ARMClang and TIClang. This commit thus explicitly unsets all of the compile option variables which are not manually defined for these compilers.
* GNU: Do not use "fat-lto-objects" flags for IPO on Apple platformsRené Bertin2024-04-241-1/+1
| | | | | | | | | | | Fat LTO objects contain both traditional object code and the LTO bitcode IR, but the GNU compiler does not support them on Apple platforms. A compile error is raised when `-f[no-]fat-lto-objects` flags are used, so avoid them. This also implies that static Fortran libraries cannot be built with IPO. Fixes: #25931

* | CMakeDetermineCompilerSupport: construct C++ modules targetsBen Boeckel2024-04-121-0/+35
| | | | | | | | | | | | | | Compilers may implement this by implementing a `_cmake_cxx_import_std` function which takes the standard version as an argument (e.g., `23`) and creating a target named `CMake::CXX${std}` that represents how `import std;` should be represented within CMake.
* | C++26: Fix C++/CUDA/HIP compile feature supportRaul Tambre2024-04-091-0/+9

| * | Modules: Factor out helpers for GNU language standard flagsTyler2024-03-293-83/+89
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | Add the following macros to `${CMAKE_ROOT}\Modules\Compiler\GNU.cmake`: * `__compiler_gnu_c_standards()` * `__compiler_gnu_cxx_standards()` These macros are used to define the `CMAKE_<LANG><STANDARD>_STANDARD_COMPILE_OPTION` and `CMAKE_<LANG><STANDARD>_EXTENSION_COMPILE_OPTION` variables for C- and C++-based languages for GCC. The macros are similar to the existing `__compiler_clang_cxx_standards()` macro found in `${CMAKE_ROOT}\Modules\Compiler\Clang.cmake`.

| * Clang: detect -resource-dir for clang-scan-depsBen Boeckel2024-02-211-0/+8
| | | | | | | | | | | | | | | | When cross-compiling, `clang-scan-deps` needs help to find the correct location of core headers such as `stddef.h`. Always determine this path and pass it when available. Fixes: #25590
* | IPO: Support duplicate object names in large archivesRuslan Baratov2024-02-155-10/+10

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When `clang-scan-deps` fails to scan (e.g., bad source syntax, junk flags, etc.), the redirection unconditionally updates the file. If this fails, the `.ddi` file timestamp is updated. If the state is then reverted (e.g., the command line returns to the state of the last successful build), the updated file is not useful, but `ninja` does not rerun because: - the command hash matches the last successful run - the output file is newer than its inputs However, since the `.ddi` file has been updated with bogus contents from a failed scan, collation fails as the `rules` array is empty (or incomplete from a batch scan). If `clang-scan-deps` were properly aware of its output file, it could use this to not write the file if any inner scan fails. Requested in https://github.com/llvm/llvm-project/issues/72875. See: https://github.com/llvm/llvm-project/issues/72875 Fixes: #25429
