This volume presents the refereed proceedings from the 14th International Symposium on Static Analysis. The papers address all aspects of static analysis, including abstract domains, abstract interpretation, abstract testing, compiler optimizations, control flow analysis, data flow analysis, model checking, program specialization, security analysis, theoretical analysis frameworks, type-based analysis, and verification systems.

Static analysis is increasingly recognized as a fundamental reasearch area aimed at studying and developing tools for high performance implementations and v- i cation systems for all programming language paradigms. The last two decades have witnessed substantial developments in this eld, ranging from theoretical frameworks to design, implementation, and application of analyzers in optim- ing compilers. Since 1994, SAS has been the annual conference and forum for researchers in all aspects of static analysis. This volume contains the proceedings of the 6th International Symposium on Static Analysis (SAS'99) which was held in Venice, Italy, on 22{24 September 1999. The previous SAS conferences were held in Namur (Belgium), Glasgow (UK), Aachen (Germany), Paris (France), and Pisa (Italy). The program committee selected 18 papers out of 42 submissions on the basis of at least three reviews. The resulting volume o ers to the reader a complete landscape of the research in this area. The papers contribute to the following topics: foundations of static analysis, abstract domain design, and applications of static analysis to di erent programming paradigms (concurrent, synchronous, imperative, object oriented, logical, and functional). In particular, several papers use static analysis for obtaining state space reduction in concurrent systems. New application elds are also addressed, such as the problems of security and secrecy.

This volume constitutes the proceedings of the third International Workshop on Static Analysis (WSA93), held in Padova, Italy, in September 1993. The objective of the international workshop series WSA is to serve as a forum for the discussion of the various aspects of static analysis in different programming paradigms. The clearly increasing mumbers of submitted papers and workshop participants point out the growing importance of static analysis techniques for logical, functional, concurrent and parallel languages as well as for parallel term rewriting systems. This proceedings contains, besides the abstracts or full papers of the invited talks given by Pascal Van Hentenryck, Peter van Roy, and Paul Hudak, full versions of the 20 contributed papers selected from a total of 68 submissions by an international program committee consisting of many renown researchers in the field. The volume is organized in sections on fixpoint computation, concurrency, parallelism, transformation, logic programs, term rewriting systems, strictness, reasoning about programs, and types.
