      simulation: do not depend on bdd numbers for ordering classes · ae0e84ac
      Alexandre Duret-Lutz authored
      Fixes #262 again.  Reported by Maximilien Colange.
      
      * spot/twaalgos/simulation.cc: Use state numbers to order classes, not
      their signatures.  The problem was that even if two simulation of the
      same automaton assign the same signature, the BDD identifier used for
      that signature might be different, and therefore the ordering obtained
      by using BDDs as keys in a map can be different.  A side-effect of
      this change is that the order of states in automata produced by
      simulation-based reduction may change; many tests had to be updated.
      * tests/core/ltl2tgba.test: Add a new test case based on Maximilien's
      report.

      Store membership to acceptance sets using bitsets, not BDDs. · 2c764fb3
      Alexandre Duret-Lutz authored
      This is a huge patch, that took over a month to complete.  The bit sets
      are currently restricted to what 'unsigned can store', but it should be
      easy to extend it to 'uint64_t' should we need it.

      src/tgba/tgbasgba.cc, src/tgba/tgbasgba.hh: Delete.  The KV
      complementation is too slow to be used in practice, and I somehow broke
      it during the conversion to bitsets.  The tgba->sgba conversion was only
      used for the KV complementation, and should be better redone on
      tgba_digraph_ptr should it be needed again.

      Remove ltl2tgba_lacim and all supporting classes. · 116fe865
      Alexandre Duret-Lutz authored
      This translator algorithm is seldom used in practice because we work
      with explicit automata everywhere, and this is only useful to build
      symbolic automata.  Furthermore, the symbolic automata produced by this
      algorithm are larger (when looked at explicitly) than those produced by
      ltl2tgba_fm or other explicit translators.
      
      The nice side effect of this removal is that we can also remove a lot of
      supporting classes, that were relying a lot on BDDs.

      Fix interpretation of {e[*]} and !{e[*]}. · cb7bdf8c
      Alexandre Duret-Lutz authored
      This follows from a discussion with Ernesto Posse.
      
      The semantics for the {...} operator we use in Spot comes from the
      cl(...) operator defined by Dax et al. (ATVA'09).  This is slightly
      different from the the way the PSL spec interprets a SERE used in the
      context of a temporal formula (appendix B.3.1.1.2, item 7).
      
      cl({a;b}[*]) would match any infinite word that starts with a;b, while
      in PSL {a;b}[*] would match any infinite word that alternates a and b.
      
      Spot documents that {SERE} in a temporal formula is interpreted like
      cl(SERE) however it failed to ignore the empty prefix of SERE.  So
      {{a;b}[*]} would match anything, because the empty word is a prefix of
      any word, and is also accepted by {a;b}[*].  Some trivial identities
      and basic rewritings were also wrongly considering these empty
      prefixes as well.
      
      This patch therefore fixes the translation and syntactic
      simplification rules, to really ignore these empty prefixes.
      
      In some future version it should probably be wise to rename this {...}
      operator as cl(...), and use {...} for the semantics given in appendix
      B.3.1.1.2 (item 7) of the PSL specs.
      
      * src/ltlast/unop.cc: Fix trivial identities.  We have
      {[*0]} = 0 and !{[*0]} = 1.
      * src/ltlvisit/simplify.cc: Fix basic rewriting rules.
      {e[*]} = {e} and !{e[*]} = !{e}.
      * doc/tl/tl.tex: Adjust documentation.
      * doc/tl/tl.bib (dax.09.atva): New entry.
      * src/tgbaalgos/ltl2tgba_fm.cc: Do not accept any
      infinite word for {e[*]} just because the empty
      prefix is matched by e[*].
      * src/tgbatest/ltl2tgba.test: Add a test case.
      * NEWS: Mention it.
      * THANKS: Add Ernesto.

      Fix translation of !{r}. · e2f70e72
      Alexandre Duret-Lutz authored
      We need a marked version of !{r} to perform breakpoint unroling.
      
      * src/ltlast/unop.cc, src/ltlast/unop.hh: Declare a NegClosureMarked
      operator.
      * src/ltlvisit/mark.hh, src/ltlvisit/mark.cc,
      src/tgbaalgos/ltl2tgba_fm.cc: Adjust to deal with NegClosureMarked
      and NegClosure as apropriate.

      src/ltlvisit/tunabbrev.cc, src/tgbaalgos/eltl2tgba_lacim.cc,
      src/tgbaalgos/ltl2taa.cc, src/tgbaalgos/ltl2tgba_lacim.cc,
      src/tgba/formula2bdd.cc: Deal with NegClosureMarked in the same way as
      we deal with NegClosure.
      * src/tgbatest/ltl2tgba.test: More tests.
      * src/ltltest/kind.test: Adjust.
      * doc/tl/tl.tex: Mention the marked negated closure.

      Ignore sub-"SERE" that have been proved useless already. · 098e121a
      Alexandre Duret-Lutz authored
      * src/tgbaalgos/ltl2tgba_fm.cc (ratexp_to_dfa::translate): Do not
      translate a subformula if we have already proved it useless in
      a previous rational expression.
      * src/tgbatest/ltl2tgba.test: Add an example, although that
      test does not ensure the subformula is ignored early in the
      translation.  I.e., it would still work without the patch.

      Trim DFAs used when translating PSL's closure operators. · b3cc033e
      Alexandre Duret-Lutz authored
      This fixes a bug where {(a&!a)[=2]} was translated either into an
      universal automaton (with simplification turned off) or in an
      empty automaton (with simplification turned on).
      
      * src/tgbaalgos/ltl2tgba_fm.cc (ratexp_to_dfa::translate): Trim
      the automaton.
      (ratexp_to_dfa::succ, ratexp_to_dfa::get_label): Deal with trimed
      states.
      (ltl_trad_visitor::visit(unop::Closure)): Likewise.
      * src/tgbatest/ltl2tgba.test, src/ltltest/reduccmp.test: New test
      cases.

      * src/ltlparse/ltlparse.yy, src/ltlparse/ltlscan.ll: Add parse
