C/C++ disambiguation using attribute grammars

We propose a novel approach to seman-tics driven disambiguation based on Attribute Grammars (AGs). AGs share the same mod-ularity model as its host grammar language, here Syntax Definition Formalism (SDF), what makes them particularly attractive for work-ing on unstable grammars, or grammar exten-sions. The framework we propose is effective, since a full ISO-C99 disambigution chain al-ready works, and the core of the hardest ambi-guities of C++ is solved. This requires specific techniques, and some extensions to the stock AG model
