	Maybe this is not a bugs. But i fail to install llvm many times and different machine(debian os).
	First, i follow the instruction:


	But during in compiling, i alway get:
	/home/yubo/git/llvm/tools/clang/lib/Basic/VirtualFileSystem.cpp: In member function ‘virtual llvm::ErrorOr<std::unique_ptr<clang::vfs::File> > {anonymous}::RealFileSystem::openFileForRead(const llvm::Twine&)’:
	/home/yubo/git/llvm/tools/clang/lib/Basic/VirtualFileSystem.cpp:262:46: error: ‘OF_None’ is not a member of ‘llvm::sys::fs’ sys::fs::openFileForRead(Name, FD, sys::fs::OF_None, &RealName))

	tools/clang/lib/Basic/CMakeFiles/clangBasic.dir/build.make:1244: recipe for target 'tools/clang/lib/Basic/CMakeFiles/clangBasic.dir/VirtualFileSystem.cpp.o' failed
