Zusammenfassung
The compilation of the relational-functional language RELFUN is enhanced by source-level (horizontal) preprocessing. A horizontal compiler transforms the language into a normal-form kernel. This includes right-hand-side propagation, static unification, sharing, pre-evaluation, and reordering. The transformations are specified as a collection of term-rewriting systems plus a control algorithm. Building on the PROLOG mode interpreter of Saumya K. Debray, a global mode or data-flow analyzer for RELFUN call patterns is developed. All compiler enhancements described are running in LISP.
