      * src/ltlvisit/reduce.hh: Mark the file as obsolete.
      (reduce): Declare this function as obsolete.
      * src/ltlvisit/reduce.cc: Define SKIP_DEPRECATED_WARNING
      so we can include reduce.hh.
      * src/sanity/includes.test: Also use SKIP_DEPRECATED_WARNING

      Maintain basic LTL properties using a bitfield inside formula objects. · 546260e7
      Alexandre Duret-Lutz authored
      This bitfield is easily updated as the formulae are constructed.
      Doing so avoids many AST recursions to compute these properties
      individually.  This patch removes the eventual_universal_visitor,
      as well as the kind_of() function.

      is_ltl_formula, is_eltl_formula, is_psl_formula, is_eventual,
      is_universal, is_marked): New methods to query formula
      properties in constant time.
      (get_props, ltl_prop): A method and structure for
      implementation as a field bit in an unsigned, for fast
      (print_formula_props): New function.
      * src/ltlast/formula.cc (print_formula_props): Implement it.

      src/ltlast/bunop.cc, src/ltlast/constant.cc, src/ltlast/multop.cc,
      src/ltlast/unop.cc, src/ltlast/automatop.cc: Compute the
      properties as instances are constructed.
      * src/ltlparse/ltlparse.yy: Update to use is_boolean() instead
      of kind_of().
      * src/ltltest/kind.cc: Update to use print_formula_props().
      * src/ltltest/kind.test: Adjust to test eventual and universal
      * src/ltlvisit/kind.cc, src/ltlvisit/kind.hh: Delete these files.
      * src/ltlvisit/Makefile.am: Remove kind.hh and kind.cc.

      Remove, no longer needed.
      (reduce_visitor, is_eventual, is_universal): Adjust to
      use formula::is_eventual(), and formula::is_universal().

      Add Reduce_Containment_Checks and Reduce_Containment_Checks_Stronger

      * src/ltltest/reduc.cc: Simplify using the reduce() interface
      instead of reduce_tau03.
      * src/tgbatest/ltl2tgba.cc: Likewise.  Add -fr5, -fr6, and -fr7
      * src/tgbatest/spotlbtt.test: Remove cases using "-c", since its
      current implementation is not always correct (and apparently
      reduces less than -fr7).
