Automated partial communication deadlock analysis after changes to Ada code
A. von Mayrhauser, Sheng-Hsien Hsueh, Pradip K. Srimani · 2002
When writing concurrent Ada programs, deadlock is always a possibility. Existing algorithms to analyze for deadlock are either very limited or relatively expensive. While the best are still quite feasible for inclusion in an Ada developer's toolbox, costs start becoming high when changes to code force repeated full re-analysis. This paper uses control-and-communication flow analysis as a basis to derive an efficient algorithm for automated partial re-analysis of Ada programs with respect to communication deadlock. Re-analysis needs are determined based on types of code changes. The paper also presents an analytic evaluation of the efficiency of the re-analysis technique.>
