      Massage the AST so that identical sub-formula share the same · 5f6d8b62
      Alexandre Duret-Lutz authored
      reference-counted formula*.  One can't call constructors for AST
      items anymore, everything need to be acquired through instance()
      class methods.
      * src/ltlast/formula.cc, src/ltlast/refformula.cc,
      src/ltlast/refformula.hh: New files.
      * src/ltlast/Makefile.am (libltlast_la_SOURCES): Add them.
      * src/ltlast/atomic_prop.cc, src/ltlast/atomic_prop.hh,
      src/ltlast/unop.cc, src/ltlast/unop.hh,
      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
      * 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/ltltest/Makefile.am (LDADD): Tweak library ordering.
      * 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
      * src/ltlvisit/lunabbrev.hh, src/ltlvisit/lunabbrev.cc,
      src/ltlvisit/tunabbrev.hh, src/ltlvisit/tunabbrev.cc,
      src/ltlvisit/nenoform.hh, src/ltlvisit/nenoform.cc: Use instance()
      methods instead of constructor.  Make these children of visitor, not
      * src/ltltest/readltl.c (main): Do not delete the formula.

      the code and helps Doxygen.
