[PATCH] D107898: [CMake] Fix recompile all .inc files with LLVM_OPTIMIZED_TABLEGEN in Visual Studio.

[Chris Bieneman via Phabricator via llvm-commits]

beanz added a comment.

Here's a little terrible blurb of CMake that should actually be a very portable solution to this:

  function(llvm_get_host_prefixes_and_suffixes)
    message("CMAKE_HOST_SYSTEM_NAME: ${CMAKE_HOST_SYSTEM_NAME}")
    include(Platform/${CMAKE_HOST_SYSTEM_NAME} OPTIONAL RESULT_VARIABLE _includedFile)
    message("_includedFile: ${_includedFile}")
    if (_includedFile)
      set(LLVM_HOST_STATIC_LIBRARY_PREFIX ${CMAKE_STATIC_LIBRARY_PREFIX} PARENT_SCOPE)
      set(LLVM_HOST_STATIC_LIBRARY_SUFFIX ${CMAKE_STATIC_LIBRARY_SUFFIX} PARENT_SCOPE)
      set(LLVM_HOST_SHARED_LIBRARY_PREFIX ${CMAKE_SHARED_LIBRARY_PREFIX} PARENT_SCOPE)
      set(LLVM_HOST_SHARED_LIBRARY_SUFFIX ${CMAKE_SHARED_LIBRARY_SUFFIX} PARENT_SCOPE)
      set(LLVM_HOST_IMPORT_LIBRARY_PREFIX ${CMAKE_IMPORT_LIBRARY_PREFIX} PARENT_SCOPE)
      set(LLVM_HOST_IMPORT_LIBRARY_SUFFIX ${CMAKE_IMPORT_LIBRARY_SUFFIX} PARENT_SCOPE)
      set(LLVM_HOST_EXECUTABLE_SUFFIX ${CMAKE_EXECUTABLE_SUFFIX} PARENT_SCOPE)
      set(LLVM_HOST_LINK_LIBRARY_SUFFIX ${CMAKE_LINK_LIBRARY_SUFFIX} PARENT_SCOPE)
    endif()
  endfunction()
  
  llvm_get_host_prefixes_and_suffixes()

If you add this blurb into llvm's `config-ix.cmake`, you can use `LLVM_HOST_EXECUTABLE_SUFFIX` the same way you just updated the patch to use `CMAKE_EXECUTABLE_SUFFIX`, and it should be portable for cross-compilation too.
