Abstract: In this paper we describe a collection of techniques for the design and implementation of concurrent compilers. We begin by describing a technique for dividing a source program into many streams so that each stream can be compiled concurrently. We discuss several compiler design issues unique to concurrent compilers including source program partitioning, symbol table management, compiler task scheduling and information flow constraints. The application of our techniques is illustrated by a complete design for a concurrent Modula-2+ compiler. After describing the structure of this compiler's performance that demonstrates that significant improvements in compilation time can be achieved through the use of concurrency

Extract: Reasons for choosing Modula-2+ To provide a realistic environment for developing and evaluating our ideas we built a prototype concurrent compiler [JW90] for the Modula-2+ superset of Modula-2 [Rov86]. Modula-2+ was chosen as the target language partly for reasons of expediency (i.e. availability of an existing compiler that served as a starting point) , but primarily because Modula-2+ is a large modern programming language that presented many challenges to the language implementor. We felt that if we could produce an efficient compiler for Modula-2+ then it would be easy to handle languages that are easier to compile concurrently such as Pascal and C. During the CCD project we implemented seven major variations of our concurrent compiler design to test various implementation strategies. The compiler described in this paper is the ?best of 7? compiler that represents the culmination of our efforts.

Modula 2+ (1984-86): With Paul Rovner and others, I designed extensions to Modula 2 which provide a safe subset, automatic storage deallocation, runtime types, exceptions, and concurrency. The language has been used at SRC and several universities to write more than a million lines of code [P. Rovner, Extending Modula 2 to build large, integrated systems.
