Documentation and Source of
the AAPT-Evaluator Generator

Abstract. Attributed abstract program trees (AAPTs) are a formalism to describe the internal representation of programs during compilation, and are used in the implementation of compiler generators. Given an AAPT-grammar with attribute evaluation rules, the AAPT-evaluator generator will generate an evaluator for attributed abstract program trees.

The complete documentation (including the source listings) of the AAPT-evaluator generator using the simple multi-pass evaluation strategy is presented. This evaluator generator is modular in design. Many of the separate modules can be (and have been) used within other compiler generators.
