Gentle Compiler Construction System

Gentle is the first compiler construction system that handles the full spectrum from analysis over transformation (AST) to (cost-based) synthesis. Instead of confronting the user with several special purpose languages, Gentle provides a uniform notation for all tasks. It is based on recursive definition and structural induction: the underlying paradigms of virtually all tasks of translation. Rules may be interpreted as grammar rules (lex/yacc), as logical statements, or in a procedural way. Members of a rule may have parameters. This results in attributed grammars.
