      Make platform information files specific to the CMake version · 7195aca5
      Brad King authored
      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.

      Remove CMake-language block-end command arguments · 9db31162
      Kitware Robot authored
      Ancient versions of CMake required else(), endif(), and similar block
      termination commands to have arguments matching the command starting the
      block.  This is no longer the preferred style.
      
      Run the following shell code:
      
      for c in else endif endforeach endfunction endmacro endwhile; do
          echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/'
      done >convert.sed &&
      git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
      egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
      egrep -z -v 'Tests/CMakeTests/While-Endwhile-' |
      xargs -0 sed -i -f convert.sed &&
      rm convert.sed

      Convert CMake-language commands to lower case · 77543bde
      Kitware Robot authored
      Ancient CMake versions required upper-case commands.  Later command
      names became case-insensitive.  Now the preferred style is lower-case.
      
      Run the following shell code:
      
      cmake --help-command-list |
      grep -v "cmake version" |
      while read c; do
          echo 's/\b'"$(echo $c | tr '[:lower:]' '[:upper:]')"'\(\s*\)(/'"$c"'\1(/g'
      done >convert.sed &&
      git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
      egrep -z -v '^(Utilities/cm|Source/kwsys/)' |

      Remove trailing whitespace from most CMake and C/C++ code · 7bbaa428
      Kitware Robot authored
      Our Git commit hooks disallow modification or addition of lines with
      trailing whitespace.  Wipe out all remnants of trailing whitespace
      everywhere except third-party code.
      
      Run the following shell code:
      
      git ls-files -z -- \
       bootstrap doxygen.config '*.readme' \
       '*.c' '*.cmake' '*.cpp' '*.cxx' \
       '*.el' '*.f' '*.f90' '*.h' '*.in' '*.in.l' '*.java' \
       '*.mm' '*.pike' '*.py' '*.txt' '*.vim' |
      egrep -z -v '^(Utilities/cm|Source/(kwsys|CursesDialog/form)/)' |
      egrep -z -v '^(Modules/CPack\..*\.in)' |
      xargs -0 sed -i 's/ \+$//'

      ENH: remove support for presetting CMAKE_SYSTEM_INFO_FILE,
      CMAKE_SYSTEM_AND_C_COMPILER_INFO_FILE, CMAKE_SYSTEM_AND_CXX_COMPILER_INFO_FILE,
      CMAKE_SYSTEM_AND_C_COMPILER_AND_PROCESSOR_INFO_FILE and CMAKE_SYSTEM_AND_CXX_COMPILER_AND_PROCESSOR_INFO_FILE
      
      Instead of presetting these variables to arbitrary filenames, users should
      set up CMAKE_SYSTEM_NAME and the compilers correctly and also create a
      Platform/ directory so these files will all follow the official cmake style,
      which should make it easier to understand and debug project which have their
      own platform/toolchain support files.
      
      -remove support for a suffix to MS crosscompilers, since this is not (yet)
      supported by cmake and might confuse users

      ENH: always provide CMAKE_SYSTEM_XXX() and MAKE_HOST_SYSTEM_XXX() variables,
      so when cross compiling the build host platform can be tested

      ENH: merge CMake-CrossCompileBasic to HEAD
      -add a RESULT_VARIABLE to INCLUDE()
      -add CMAKE_TOOLCHAIN_FILE for specifiying your (potentially crosscompiling) toolchain
      -have TRY_RUN() complain if you try to use it in crosscompiling mode (which were compiled but cannot run on this system)
      -use CMAKE_EXECUTABLE_SUFFIX in TRY_RUN(), probably TRY_RUN won't be able to
      run the executables if they have a different suffix because they are
      probably crosscompiled, but nevertheless it should be able to find them
      -make several cmake variables presettable by the user: CMAKE_C/CXX_COMPILER, CMAKE_C/CXX_OUTPUT_EXTENSION, CMAKE_SYSTEM_NAME, CMAKE_SYSTEM_INFO_FILE
      -support prefix for GNU toolchains (arm-elf-gcc, arm-elf-ar, arm-elf-strip etc.)
      -move ranlib on OSX from the file command to a command in executed in cmake_install.cmake
      -add support for stripping during install in cmake_install.cmake
      -split out cl.cmake from Windows-cl.cmake, first (very incomplete) step to support MS crosscompiling tools
      -remove stdio.h from the simple C program which checks if the compiler works, since this may not exist for some embedded platforms
      -create a new CMakeFindBinUtils.cmake which collects the search fro ar, ranlib, strip, ld, link, install_name_tool and other tools like these
      -add support for CMAKE_FIND_ROOT_PATH for all FIND_XXX commands, which is a
      list of directories which will be prepended to all search directories, right
      now as a cmake variable, turning it into a global cmake property may need
      some more work
      -remove cmTestTestHandler::TryExecutable(), it's unused
      -split cmFileCommand::HandleInstall() into slightly smaller functions
