Throughout program execution, types may stabilize, variables may become constant, and code sections may turn out to be redundant - all information that is used by just-in-time (JIT) compilers to achieve peak performance. Yet, since JIT compilation is done on demand for individual code parts, global observations cannot be made. Global data analysis, however, is an inherently expensive process, that collects information over large data sets. Thus, it is infeasible in dynamic compilers. With this project, we propose integrating data analysis into a state-of-the-art runtime. The goal is to gather detailed run-time information for compiler optimizations to improve performance of data-heavy applications.
