Standard compilers optimize execution time for the average case. However, in hard real-time systems the worst-case execution time (WCET) is of primary importance. Therefore, a compiler for real-time systems shall include optimizations that aim to minimize the WCET. One effective compiler optimization is method in lining. It is especially important for languages, like Java, where small setter and getter methods are considered good programming style. In this paper we present and explore WCET driven in lining of Java methods. We use the WCET analysis tool for the Java processor JOP to guide to optimization along the worst-case path. The tool JCopter is integrated with the WCET analysis tool and is used to explore different in lining strategies. On real-time benchmarks the optimization results in a reduction of the WCET by a few percent up to a factor of about 2.
