The DEC High Performance Fortran 90 compiler front end

Digital has developed a compiler for full Fortran 90 and the High Performance Fortran extensions to Fortran 90. This compiler targets Digital´s Alpha workstations, servers, shared-memory SMP servers, and distributed memory AdvantageCluster and workstation farm systems. This paper gives an overview of the structure of the compiler´s front end component, responsible for lexical analysis, syntax analysis, and semantic analysis. It also presents, by means of an example, the compiler´s high-level platform-independent common intermediate representation
