Polly - Polyhedral optimizations for LLVM

AST Generation Paper published in TOPLAS The July issue of TOPLAS contains a 50 page discussion of the AST generation techniques used in Polly. This discussion gives not only an in-depth description of how we (re)generate an imperative AST from our polyhedral based mathematical program description, but also gives interesting insights about: Schedule trees: A tree-based mathematical program descrip
