An attributed ELL(1)-parser generator

Abstract

TCGS is an acronym for Twente Compiler Generating System. It has been developed at the Compiler Methodology Group at the University of Twente. The system consists of a scanner generator, a combined parser and attribute-evaluator generator, a standard routine module, and an interpreter. The standard routine module contains type definitions, routines for the storage and retrieval of declaration information, routines that support attribute evaluation, and routines that support code generation for a hypothetical stack machine. The linker builds a complete compiler in VAX Pascal from the generated attributed parser and scanner, the standard routine module, and possibly, user defined modules. The interpreter, useful in compiler courses, is used to execute programs in target code. This paper is devoted to the parser and attribute-evaluator generator.
