An optimizer for the PanLanguage was implemented in Stratego as part of a research on InliningStrategies. It performs the following optimizations:
  • FunctionInlining?
  • ConstantFolding?
  • CommonSubexpressionElimination?
  • CodeMotion?

The optimizer uses the frontend from the compiler for the TigerLanguage?, which means Pan programs must be written in Tiger.

A master thesis which discusses this implementation is available. It has the following abstract.

All modern compilers provide inlining, an optimization which replaces a function call by the function body. Implementations of inlining are usually focused on specific algorithms to decide which functions should be inlined or specific source languages. This report instead describes the implementation of a general inlining implementation in the program transformation language Stratego. This inliner should be usable for different source languages and decision algorithms. The implementation separates the analysis and transformation of the program, the traversal of the program and the decision when to do inlining. In addition, the implementation of several other optimizations that are enabled by inlining is discussed in the context of the highly optimizable Pan language.
