      twa_graph: add support for universal initial states · 48c812a5
      Alexandre Duret-Lutz authored
      The only missing point is that the HOA parser cannot deal with multiple
      universal initial states, as seen in parseaut.test.
      
      * spot/graph/graph.hh (new_univ_dests): New function, extracted from...
      (new_univ_edge): ... this one.
      * spot/twa/twagraph.hh (set_univ_init_state): Implement using
      new_univ_dests.
      * spot/twaalgos/dot.cc, spot/twaalgos/hoa.cc, python/spot/impl.i:
      Add support for universal initial states.
      * spot/parseaut/parseaut.yy: Add preliminary support for
      universal initial states.  Multiple universal initial states
      are still not supported.
      * tests/core/alternating.test, tests/core/parseaut.test,
      tests/python/alternating.py: Adjust tests and exercise this new feature.

      Alexandre Duret-Lutz authored
      * spot/twaalgos/dot.cc: Handle universal destinations.
      Ignore option 's' for alternating automata.
      * tests/core/alternating.test: New file.

      parseaut: preliminary support for reading alternating automata · e6203686
      Alexandre Duret-Lutz authored
      Currently this only reads universal branches.  The parser (and the
      automaton code) do not support universal initial states.
      
      * spot/parseaut/parseaut.yy: Read universal branches.  Deal with
      the no-univ-branch/!univ-branch change in HOA 1.1.
      * tests/python/alternating.py: Read the output of print_hoa.
      * tests/core/parseaut.test: Adjust test output, and add more tests.

      twa_graph: add basic support for alternation · 6aad559c
      Alexandre Duret-Lutz authored
      This only allows creating universal edges, and reading the associated
      destinations.
      
      * spot/twa/twagraph.hh (new_univ_edges, univ_dests, is_alternating): New
      function.
      * python/spot/impl.i: Add Python bindings.
      * tests/python/alternating.py: New file.
      * tests/Makefile.am: Add it.

      graph: replace the existing "alternating" interface · 4903f086
      Alexandre Duret-Lutz authored
      * spot/graph/graph.hh: Use the sign bit of destination state X to
      designate a universal edge.  Store the destinations of such an edge in a
      separate array, at index ~X.
      * spot/graph/ngraph.hh, tests/core/graph.cc, tests/core/graph.test,
      tests/core/ngraph.cc: Adjust test case to the new interface.

      install back the safety check of includes.test · 7824005d
      Alexandre Duret-Lutz authored
      Compilation of each header file alone, as a safety check, was removed
      when introducing "#pragma once" because we did not have to check for
      possible double inclusion.  However we still need to compile each
      header to make sure they are self-contained.
      
      * tests/sanity/includes.test: Compile each header.
      * tests/run.in: Export various compiler and directory flags.
