ACER: An AST-based Call Graph Generator Framework

Andrew Chen, Yanfu Yan, Denys Poshyvanyk

Abstract: We introduce ACER, an AST-based call graph generator framework. ACER leverages tree-sitter to interface with any language. We opted to focus on generators that operate on abstract syntax trees (ASTs) due to their speed and simplicitly in certain scenarios; however, a fully quantified intermediate representation usually provides far better information at the cost of requiring compilation. To evaluate our framework, we created two context-insensitive Java generators and compared them to existing open-source Java generators.Code: https://github.com/WM-SEMERU/ACER
