21 Another useful project on Windows is `Clang <http://clang.llvm.org/>`_. 21 The second piece is the `Clang <http://clang.llvm.org/>`_ front end. This

23 Windows, but does not currently understand all of the Microsoft extensions 23 bitcode. Clang typically uses LLVM libraries to optimize the bitcode and emit
24 to C and C++. Because of this, clang cannot parse the C++ standard library 24 machine code. LLVM fully supports the COFF object file format, which is
25 included with Visual Studio, nor parts of the Windows Platform SDK. However, 25 compatible with all other existing Windows toolchains.
26 most standard C programs do compile. Clang can be used to emit bitcode, 26
