A parallel approach to code generation for Fortran like compilers

Abstract

It has been shown by Lincoln and others that vector operations can be used to perform lexical analysis of FORTRAN source code. This paper presents techniques for code generation using parallel programming methods developed on the CDC STAR-100. Methods are presented for handling arithmetic assignment statements, DO loops, IF statements, and parenthetical expressions. A CO-NO table syntactical analysis is performed using the numeric vector from lexical analysis to produce output code for arithmetic expressions. Code for DO loops and IF statements is then merged into the object code vector.
