      Add a sanity check for installed private headers. · aeca44e0
      Alexandre Duret-Lutz authored
      If an installed header has an associated *.cc file (in the source
      tree), but does not declare any SPOT_API symbol, something is fishy.
      Either that header should not be installed, or it is missing the
      SPOT_API markers.

      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.
