svn checkout http://llvm.org/svn/llvm-project/polly/trunk polly

My failed trial was Polly from Git.

git clone git://repo.or.cz/polly.git

Its "git log" is
------------------

    Add forgotten Makefile

commit 141ea11265b81479d290e97779fce0a90a51d8f8

    Add new JSON library that is licensed under public domain.
    
    Also remove the old GPL licensed JSON library.
    
------------------
