      FM: collect implied formulae in & arguments; do not to translate them · c5b294c7
      Alexandre Duret-Lutz authored
      * src/tgbaalgos/ltl2tgba_fm.cc (implied_subforfmulae): New function.
      (ltl_trad_visitor::visit(const binop*)): Use it.  This is an attempt
      to correct the unoptimal translation of 'Fa & GFa' left by previous
      patch.  It still fails to optimize 'Fa & GF(a&b)', but this is not a
      regression compared to previous version.

      Faster translation of GFa. · 1b143067
      Alexandre Duret-Lutz authored
      * src/tgbaalgos/ltl2tgba_fm.cc: Add a "recurring" mode for the
      translation of the child of G.  This generalizes Couvreur's original
      trick to translate GFa as (a|Prom(a))&X(GFa) without generating an
      intermediate GF(a)&F(a) state that would have to be merged with GF(a)
      latter.  This implementation will also speedup formulas such a G((a U
      b) & (c M d)).  With this patch, translating GF(p1) & GF(p2) &
      ... GF(p20) into a TGBA takes 57s instead of 128s on my computer.
      However it alsos causes some formulas to be translated into larger
      automata that are not immediately reduced (the simulation-reduction is
      needed).  For instance Fa & GFa now has a different signature than
      GFa, so translating 'Fa & GFa' generates two states where is used to
      generate only one.

      Use 'const formula*' instead of 'formula*' everywhere. · bf62d439
      Alexandre Duret-Lutz authored
      The distinction makes no sense since Spot 0.5, where we switched from
      mutable furmulae to immutable formulae.  The difference between
      const_visitor and visitor made no sense either.  They have been merged
      into one: visitor.
