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.
