      Introduce rational operators and trivial simplification rules. · 546559b8
      Alexandre Duret-Lutz authored
      Trivial simplifications rules (such as "FFa=Fa" or "x&1=x")
      are performed any time a formule is instanciated.
      * src/ltlast/constant.hh, src/ltlast/constant.cc
      (true_instance, true_instance_): Declare the true_instance_ as a
      static member, and move true_instance() into the .hh so it gets
      inlined.  Have true_instance_ as a class variable will ensure that
      it is the first formula instantiated.  Binop simplifications rely
      on this to order arguments.
      (false_instance, false_instance_): Likewise.
      (empty_word_instance, empty_word_instance_): New method and static
      * src/ltlast/formula.hh (formula::formula): If max_count_ ever
      loops, skip the first three values so that constants always have
      smaller hash codes.
      * src/ltlast/binop.hh, src/ltlast/binop.cc (instance): Add
      simplifications and document them.
      * src/ltlast/multop.hh (multop::Concat): New operator.
      * src/ltlast/multop.cc (op_name): Handle Concat.
      (instance): Inline Concat arguments without reordering.  Handle
      absorbent and neutral elements for all operators.
      * src/ltlast/unop.hh (unop::Star): New operator.
      * src/ltlast/unop.cc (op_name): Handle Star.
      (instance): Handle Star, and add trivial simplifications for
      other unary operators.
      * src/ltlparse/ltlparse.yy (OP_CONCAT, OP_STAR, CONST_EMPTYWORD):
      Declare these new operators and add rules for them.
      * src/ltlparse/ltlscan.ll (OP_CONCAT, OP_STAR, CONST_EMPTYWORD):
      Output these new operators.
      * src/ltltest/equals.test: New tests.
      * src/ltltest/parse.test: Remove redundant test.

      to destroy them.
