Resource Analysis of Complex Programs with Cost Equations.
Report, Bibliographie
Kurzbeschreibung (Abstract)
We present a novel static analysis for inferring precise complexity bounds of imperative and recursive programs. The analysis operates on cost equations. Therefore, it permits uniform treatment of loops and recursive procedures. The analysis is able to provide precise upper bounds for programs with complex execution flow and multi-dimensional ranking functions. In a first phase, a combination of control-flow refinement and invariant generation creates a representation of the possible behaviors of a (possibly inter-procedural) program in the form of a set of execution patterns. In a second phase, a cost upper bound of each pattern is obtained by combining individual costs of code fragments. Our technique is able to detect dependencies between different pieces of code and hence to compute a precise upper bounds for a given program. A prototype has been implemented and evaluated to demonstrate the effectiveness of the approach.
