Implementation of a Didactic Compiler for a superset of PL/0

TL;DR

This paper presents a didactic compiler for a PL/0 superset that uses XML files to reflect the build phases, enhancing understanding of compiler construction processes.

Contribution

It introduces a compiler architecture that encodes build phase information as XML, facilitating educational insights into compiler design.

Findings

Build phases are effectively represented as XML files.

The compiler demonstrates clear modularity and traceability.

Educational value is enhanced through XML-based phase reflection.

Abstract

This article describes the features of a compiler for a superset language of the well-known PL/0 created by Niklaus Wirth. The main feature is that it implements the build phases in such a way that the information passed between each one is reflected as an XML file.
