      Before this change, all automata would construct their own · cab3be97
      Alexandre Duret-Lutz authored
      dictionaries (map of BDD variables to LTL formulae).  This was
      cumbersome, because to multiply two automata we had to build a
      common dictionary (the union of the two LTL formula spaces), and
      install wrappers to translate each automaton's BDD answers into
      the common dictionary.  This translation, that had to be repeated
      when several products were nested, was time consuming and was a
      hindrance for some optimizations.
      In the new scheme, all automata involved in a product must
      share the same dictionary.  An empty dictionary should be
      constructed by the user and passed to the automaton' constructors
      as necessary.
      This huge change removes most code than it adds.

      * src/ltlast/atomic_prop.hh: Declare instance_count().
      * src/ltlast/binop.hh, src/ltlast/unop.hh, src/ltlast/multop.hh:
      Likewise.  Also, really inherit for ref_formula this time.
      * src/ltlast/atomic_prop.cc, src/ltlast/binop.cc,
      src/ltlast/unop.cc, src/ltlast/multop.cc: On destruction, suppress
      the instance from the instance map.  Implement instance_count().
      * src/ltlast/formula.cc, src/ltlast/formula.hh,
      src/ltlast/ref_formula.cc, src/ltlast/ref_formula.hh: Add virtual
      destructors.
      * src/ltlparse/ltlparse.yy: Recover from binary operators with
      missing right hand operand (the point is just to destroy the
      the left hand operand).
      * src/ltltest/equals.cc, src/ltltest/readltl.cc,
      src/ltltest/tostring.cc: Destroy used formulae.  Make sure
      instance_count()s are null are the end.
      * src/ltltest/parseerr.test: Adjust expected result, now
      that the parser lnows about missing right hand operands.
      * src/ltlvisit/destroy.hh, src/ltlvisit/destroy.cc,
      src/ltlvisit/postfix.hh, src/ltlvisit/postfix.cc: New files.
      * src/ltlvisit/Makefile.am (libltlvisit_la_SOURCES): Add them.

      occurring twice in the rewritten expression.

      reference-counted formula*.  One can't call constructors for AST
      items anymore, everything need to be acquired through instance()

      src/ltlast/binop.cc, src/ltlast/binop.hh: Make the constructor
      and destructor protected.  Define a static function `instance()'
      to get an instance with specific argument.  Use a map called
      `instances' to store all known instances.  Inherit from
      ref_formula.
      * src/ltlast/constant.hh, src/ltlast/constant.cc: Protect
      the constructor and destructor.  Provide the false_instance()
      and true_instance() functions instead.
      * src/formula.hh (ref, unref, ref_, unref_): New methods.
      * src/ltlast/multop.cc, src/ltlast/multop.hh: Protect
      the constructor, destructor, as well as the add() method.
      Provides the instance(), and add() class methods instead.
      Store children_ as a pointer.
      * src/ltlenv/defaultenv.cc (require): Adjust to
      call atomic_prop::instance.
      * src/ltlparse/ltlparse.yy: Adjust to call instance() functions
      instead of constructors.

      * src/ltlvisit/clone.hh (clone_visitor): Inherit from visitor,
      not const_visitor, and adjust all prototypes appropriately.
      * src/ltlvisit/clone.cc (clone_visitor): Likewise.
      Call ref() or instance() methods instead of copy constructors.
      * src/ltlvisit/equals.cc: Simplify atomic_prop and constant
