python setup.py build --compiler=clang-cl

LLVM Windows Symbolic Link Maker

The huge size of LLVM Windows installation can be reduced dramatically by using Windows symbolic link (see mklink command.

Usage

Just copy llvm\llvm-link.bat to LLVM installation path (e.g.: C:\Program Files\LLVM\) and run it (may require Administrator privilege).
