      remfin: simplify tra_to_tba using generic emptiness check · 935c412d
      Alexandre Duret-Lutz authored 
      * spot/twaalgos/remfin.cc (tra_to_tba): Remove the SCC-emptiness
check that was done by creating a temporary automaton.  Use the
scc_info::check_scc_emptiness() function instead.

spot/twaalgos/sccinfo.hh (scc_info::check_scc_emptiness): Mark
this function as const.
(scc_and_mark_filter): Make sure we only combine with a lower filter
of the same type.
* spot/twaalgos/genem.cc: Remove one stray debugging statement.
* tests/python/genem.py: Remove a duplicate test.
