Summary: As it is widely known, multi-core computers are broadly used these days, and automatic parallelization of sequential programs is still a challenge. In this context, we propose a set of code transformations to be applied automatically by a tool in order to transform sequential legacy systems into their parallel version. We implement these transformations by applying a lightweight source code analysis based on rewritable AST (Abstract Syntax Tree). Since it is not always possible to automatically parallelize the code, we also implemented some specific analyses in order to report possible changes that would allow specific parallelization. Additionally, we present some examples in which these transformations were conducted and the corresponding performance experiments.
