# Compute the directory in which to run the test.
Make platform information files specific to the CMake version 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.

CMakeDetermineCompilerId: Optionally try some flags before no flags 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.

QNX: Introduce QCC compiler id for that QNX platform compiler. Introduce policy CMP0047 to control resetting the id for compatibility. De-duplicate content in the QNX platform file by including the GNU one. QNX is a form of GNU platform. Do not clear CMAKE_SHARED_LIBRARY_${lang}_FLAGS variables. They are populated again later by the Compiler/GNU.cmake file anyway. Modify the CMAKE_CXX_COMPILE_OBJECT variable only when the QCC compiler id is in use, and the language is CXX. Use the QNX recommended flag for QCC instead of the gcc compatible -x flag. Populate new module files to handle system includes and depfiles when using the QCC compiler. Remove code which unsets the system include and depfiles related variables. When a GNU driver is used instead of the QCC one, the appropriate flags will be used. These variables were previously cleared for lowest-common-denominator compatibility with both drivers.

Ninja: Detect MSVC /showIncludes prefix with compiler flags (#15596) 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.

Without the option the compiler may warn and ignore preprocessor lines instead of failing with an error. Detect the warning and treat it as failure so that we move on to try /fpp and detect the correct id. Without this it works only by luck because Intel is the first compiler id in our detection source file.

QNX: Fix detection of QCC compiler id (#15349) In commit v3.1.0-rc1~113^2 (Use a more reliable regex for extracting binary INFO strings, 2014-09-03) the matching of INFO: strings was made more strict and no longer matches just "INFO:qnxnto". Use "INFO:qnxnto[]" instead to conform to the new pattern.

QNX: Introduce QCC compiler id for that QNX platform compiler. Introduce policy CMP0047 to control resetting the id for compatibility. De-duplicate content in the QNX platform file by including the GNU one. QNX is a form of GNU platform. Do not clear CMAKE_SHARED_LIBRARY_${lang}_FLAGS variables. They are populated again later by the Compiler/GNU.cmake file anyway. Modify the CMAKE_CXX_COMPILE_OBJECT variable only when the QCC compiler id is in use, and the language is CXX. Use the QNX recommended flag for QCC instead of the gcc compatible -x flag. Populate new module files to handle system includes and depfiles when using the QCC compiler. Remove code which unsets the system include and depfiles related variables. When a GNU driver is used instead of the QCC one, the appropriate flags will be used. These variables were previously cleared for lowest-common-denominator compatibility with both drivers.

Fortran: Add infrastructure to detect compiler version (#15372) Fortran does not offer syntax to compose a string literal at preprocessing time from numeric compuations. Instead encode each digit of each component as a separate INFO string and compose them in CMake code after extraction. Support MAJOR, MINOR, PATCH, and TWEAK components with up to 8 digits each.

De-duplicate content in the QNX platform file by including the GNU one. QNX is a form of GNU platform. Do not clear CMAKE_SHARED_LIBRARY_${lang}_FLAGS variables. They are populated again later by the Compiler/GNU.cmake file anyway. Modify the CMAKE_CXX_COMPILE_OBJECT variable only when the QCC compiler id is in use, and the language is CXX. Use the QNX recommended flag for QCC instead of the gcc compatible -x flag. Populate new module files to handle system includes and depfiles when using the QCC compiler. Remove code which unsets the system include and depfiles related variables. When a GNU driver is used instead of the QCC one, the appropriate flags will be used. These variables were previously cleared for lowest-common-denominator compatibility with both drivers.

Convert CMake-language commands to lower case Ancient CMake versions required upper-case commands. Later command names became case-insensitive. Now the preferred style is lower-case.

Detect a COMPILER_ID also for ASM. For assembler, the "compiler ID" cannot be detected by "compiling" a source file, since there is not source file all assemblers understand. Instead the function CMAKE_DETERMINE_COMPILER_ID_VENDOR() is used to run the assembler and check its output. For this the CMAKE_DETERMINE_COMPILER_ID_VENDOR() function had to be extended so that it creates the run directory if it doesn't exist yet. In CMakeASMInformation.cmake now also CMAKE_ASM_COMPILER_ID is used (but there are no such files yet, will come with the support for the IAR toolchain). Alex

Make platform information files specific to the CMake version 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.

Quote references to the variable in Modules/CMake(C|CXX|Fortran)Information.cmake Modules/CMakeDetermineCompilerId.cmake to avoid dropping arguments from commands that expect them.
