Apparently their hash tables store the hash functions in a const
member, and this requires a user-supplied default constructor.
Reported by Étienne Renault.
* src/misc/hash.hh: Add an empty constructor to all hash functions.
* src/tgbaalgos/dtbasat.cc, src/tgbaalgos/dtgbasat.cc: Record
statistics about intermediate automata if SPOT_SATLOG is set to some
filename, and display intermediate automata if SPOT_SATSHOW is set.
* bench/dtgbasat/stat.sh, bench/dtgbasat/stats.sh,
bench/dtgbasat/tabl.pl, bench/dtgbasat/tabl1.pl,
bench/dtgbasat/tabl2.pl, bench/dtgbasat/tabl3.pl,
bench/dtgbasat/tabl4.pl: Gather these extra statistics.
* src/tgbaalgos/dtbasat.cc, src/tgbaalgos/dtgbasat.cc: Compute the
actual number of reachable states in the produced automaton to prepare
the next iteration.
* src/misc/satsolver.hh, src/misc/satsolver.cc: Present
the SAT solver as an object with a stream interface, to
prepare for a better implementation.
* src/tgbaalgos/dtbasat.cc, src/tgbaalgos/dtgbasat.cc:
Adjust to the new interface, removing all the handling
of temporary files.
* src/tgbatest/readsat.cc: Adjust.
* src/tgbaalgos/dtbasat.cc, src/tgbaalgos/dtgbasat.cc: Rewrite the
loops that number the states of the reference automaton so that
they declare CNF variable numbers in the same order as the states
of the automaton.
* src/ltlvisit/randomltl.cc: Fix generation of formulas when unary or
binary operators are missing.
* src/ltlvisit/apcollect.cc, src/ltlvisit/apcollect.hh
(destroy_atomic_prop_set): New function.
* src/bin/randltl.cc: Use it, and also honnor --boolean-priorities
when generating SEREs.
* src/ltltest/rand.test: New file.
* src/ltltest/Makefile.am: Add it.
* wrap/python/spot.i (spot::ltl::parse_error_list,
spot::tgba_parse_error_list): Add a __bool__ method, that is used
instead of __nonzero__ in Python 3.
* wrap/python/tests/interdep.py, wrap/python/tests/parsetgba.py:
Force destruction order.
* NEWS: Update.
* src/misc/bitvect.cc, src/misc/bitvect.hh: Do
not assume the two bitvect with the same size have
the same number of allocated blocks. Fix an
assertion in extra_range().
* src/misc/bitvect.cc: Conditionally declare fnv<8>, so that the C++
parser does not choke on 14695981039346656037UL when compiling on a
32bit host. Problem observed with g++ 4.0.1 and 4.2.1 on Darwin.
* src/ltlparse/ltlscan.ll, src/ltlparse/parsedecl.hh (flex_set_buffer):
Take a std::string as argument and call yy_scan_bytes() with
the string size() instead of calling yy_scan_string() which does
strlen() on the supplied string.
* src/ltlparse/ltlparse.yy: Adjust calls.
* src/eltlparse/eltlscan.ll, src/eltlparse/parsedecl.hh,
src/eltlparse/eltlparse.yy: Use a similar interface. This
also fixes a memory leak as the scanned buffer was not
released.
