A framework for interprocedural optimization in the presence of dynamic class loading
Dynamic class loading during program execution in the JavaTM Programming Language is an impediment for generating code that is as e cient as code generated using static wholeprogram analysis and optimization. Whole-program analysis and optimization is possible for languages, such as C++, that do not allow new classes and/or methods to be loaded during program execution. One solution for performing wholeprogram analysis and avoiding incorrect execution after a new class is loaded is to invalidate and recompile a ected methods. Runtime invalidation and recompilation mechanisms can be expensive in both space and time, and, therefore, generally restrict optimization. To address these drawbacks, we propose a new framework, called the extant analysis framework, for interprocedural optimization of programs that support dynamic class (or method) loading. Given a set ofclasses comprising the closed world, we perform an o ine static analysis which partitions references into two categories: (1) ...
