Recent work on weighted-pushdown systems shows how to generalize interprocedural-dataflow analysis to answer “stack-qualified queries”, which answer the question “what dataflow values hold at a program node for a particular set of calling contexts?” The generalization, however, does not account for precise handling of local variables. Extended-weighted-pushdown systems address this issue, and provide answers to stack-qualified queries in the presence of local variables as well.
