This thesis presents Dava, a Java bytecode to Java source code decompiler built on top of the Soot framework., The Java Virtual Machine Specification of valid bytecode is much less restrictive than the Java Language Specification of valid Java source…

Many compiler analyses and optimizations require precise information about the behaviour of pointers in order to be effective. Points-to analysis is a technique for computing this information that has been studied extensively over the last decade. Most of this research…

Effective dynamic virtual-machine optimization depends on quickly finding and optimizing frequently-executed code regions. Such regions are naturally represented with a trace-cache, a collection of long, frequently-executed sequences of instructions. An ideal trace-cache is small and captures the majority of the…

This thesis presents a new algorithm to compute the probability that a state in a labeled Markov chain model satisfies an LTL specification. A solution to this problem was given by Courcoubetis & Yannakakis in 1995, but unlike their solution…

Program tracing is a common technique employed by software and hardware developers who are interested in characterizing the dynamic behavior of complex software systems. However, despite the popularity of trace-driven analyses, there are surprisingly few options for encoding trace data…
