- We present a pointer analysis algorithm designed for source-to-source transformations. Existing techniques for pointer analysis apply a collection of inference rules to a dismantled intermediate form of the source program, making them difficult to apply to source-to-source tools that generally work on abstract syntax trees to preserve details of the source program. Our pointer analysis algorithm operates directly on the abstract syntax tree of a C program and uses a form of standard dataflow analysis to compute the desired points-to information. We have implemented our algorithm in a source-to-source translation framework and experimental results show that it is practical on real-world examples.
