Abstract
A table-driven attribute parser for checking the consistency and completeness of attribute assignments in a source program is generated by expressing the syntax rules, semantic restrictions and default assignments as a single context-free grammar compatible with a grammar processor, or parser generator, and processing the context-free grammar to generate an attribute parser including a syntax table and a parse driver. The table-driven attribute parser is incorporated into a compiler.
