A framework for module-based language processors

A system composed of interconnected modules is a module-based system. We present an object-oriented (0-0) framework for the development of processors for module-based systems, such as compilers for 0-0 languages, linkers/loaders, and tools for user/system libraries. We claim t h a t this framework, named Jigsaw, can reduce the development effort for such processors and also serve as a basis for interoperability among them. We address the issues of (i) how the abstractions in Jigsaw can be formulated as a framework, and (ii) how Jigsaw can be extended to construct processors for module-based languages, in t h e context of our prototype implementation in C-r-f-.1
