The series of Static Analysis S- posia is a forum for the presentation and discussion of advances in the area. This volume contains the papers presentedat the EighthInternationalStatic Analysis Symposium (SAS 2001), which was held July 16{18, 2001 at the S- bonne in Paris, France. Previous SAS symposia were held in Santa Barbara, CA, USA (LNCS 1824), Venice, Italy (LNCS 1694), Pisa, Italy (LNCS 1503), Paris, France (LNCS 1302), Aachen, Germany (LNCS 1145), Glasgow, UK(LNCS983), Namur, Belgium(LNCS864), followingtheinternationalwo- shop WSA in Padova, Italy (LNCS 724), Bordeaux, France (Bigre Vol. 81-82) and JTASPEFL/WSA, Bordeaux, France (Bigre Vol. 74). The program committee meeting was held at the Ecole Normale Sup erieure in Paris on March 31, 2001, and 21 papers were selected from 62 submissions.

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.

It is well documented that fully automatic rigorous verification of complex software is very challenging and perfection is impossible. This monograph presents abstract interpretation and shows how its principles can be successfully applied to cope with the difficulties inherent to formal verification. It discusses the principles of static analysis by abstract interpretation, and reports on the automatic verification of the absence of runtime errors in large embedded aerospace software by static analysis based on abstract interpretation. The first industrial applications concerned synchronous control/command software in open loop. Recent advances consider imperfectly synchronous programs, parallel programs, and target code validation as well. Future research directions on abstract interpretation are also discussed in the context of aerospace software.
