A Haskell Implementation of a Rule-Based Program Transformation for C Programs

Abstract. Obtaining good performance when programming heterogeneous computing platforms poses significant challenges for the programmer. We present a program transformation environment, implemented in Haskell, where architectureagnostic scientific C code is transformed into a functionally equivalent one better suited for a given platform. The transformation rules are formalized in a domainspecific language (STML) that takes care of the syntactic and semantic conditions required to apply a given transformation. STML rules are compiled into Haskell function definitions that operate at AST level. Program properties, to be matched with rule conditions, can be automatically inferred or, alternatively, stated as annotations in the source code. Early experimental results are described.
