* src/misc/intvcmp2.cc (int_array_array_compression): Specify full
type of stream_compression_base<int_array_array_compression> in
constructor to please g++ versions <= 4.3.
* src/misc/intvcomp.cc (stream_compression_base::run): Limit
repeatitions to 40, not 42.
(stream_decompression_base::refill): Refill the end of the stream
with 0.
(stream_decompression_base::look_n_bits): Add assertion.
* src/tgbatest/intvcomp.cc: Add a new test case.
* src/misc/intvcomp.cc, src/misc/intvcomp.cc: Add interfaces to
compress vector<int> to vector<unsigned>.
* src/tgbatest/intvcomp.cc: Test them.
* src/sanity/style.test: Refine check to avoid a spurious report.
* configure.ac: Do not add CXXFLAGS and CFLAGS in ac_configure_args,
it causes problem when using config.cache. Instead ...
* m4/devel.m4: Add --enable-devel or --disable-devel on
ac_configure_args, now that BuDDy understands that.
* iface/dve2/dve2.cc: Adjust to use the new mspool allocator,
and get rid of the std::vector used to store compressed states.
* src/misc/intvcomp.hh: Add an "int* -> int*" interface
in addition to the "int* -> vector<unsigned>*" interface.
* src/tgbatest/intvcomp.cc: Test the two interfaces.
* iface/dve2/dve2.cc (dve2_compressed_state): New class.
(callback_context): Deal with general state*s, not dve2_state*s.
(transition_callback_compress): New function.
(dve2_kripke): Take a compress option.
(get_init_state, compute_state_condition, succ_iter,
format_state, state_condition): Handle compressed states.
(get_vars, compute_state_condition_aux): New helper methods.
* iface/dve2/dve2.hh (load_dve2): Add a compress option.
* iface/dve2/dve2check.cc: Add a -z option.
* iface/dve2/finite.test, iface/dve2/dve2check.test: Add more
tests.
* wrap/python/tests/setxor.py, wrap/python/tests/bddnqueen.py:
Clean all used bdd variables before calling bdd_done(), so that
bdd_delref() is never called after bdd_done(). In NDEBUG builds,
bdd_delref() does not check whether the BuDDy is running or not,
and calling it after bdd_done() will crash.
* src/tgba/tgbaexplicit.cc, src/tgba/tgbaexplicit.hh: Merge
state_explicit and tgba_explicit::state. In the past,
state_explicit was a small object encapsulating a pointer to the
persistent tgba_explicit::state; and we used to clone() and
destroy() a lot of state_explicit instance. Now state_explicit is
persistent, and clone() and destroy() have no effects.
* src/tgba/tgbareduce.cc: Adjust, since this inherits from
tgbaexplicit and uses the internals of state_explicit.
* src/tgbatest/reductgba.cc: Fix deletion order for automata.
* src/tgba/tgba.hh (last_support_conditions_input_,
last_support_variables_input_): Make these protected, so
they can be zeroed by tgba_explicit.
The gain is not very impressive. The runtime of the first example
in iface/dve2/README (also in dve2check.test) is 15% faster.
* src/tgba/tgbaproduct.hh (tgba_succ_iterator_product): Move ...
* src/tgba/tgbaproduct.cc (tgba_succ_iterator_product,
tgba_succ_iterator_product_common): ... in these two classes.
(tgba_succ_iterator_product_kripke): New class to speedup
successor computation on Kripke structures. We can assume that
all the transitions leaving the same state have the same label.
(tgba_product::tgba_product, tgba_product::succ_iter): Use
tgba_succ_iterator_product_kripke when appropriate.
(tgba_product_init::tgba_product_init): Adjust for the case
where tgba_product did reverse its operands.
* wrap/python/spot.i, wrap/python/buddy.i: Include <cstddef>
because Swig 2.0.2 uses ptrdiff_t and does not do the include
itself. In g++ most libstdc++ standard headers have been changed
to no longer include <cstddef> as an implementation detail, so
the difference shows.
* src/ltlvisit/reduce.cc (reduce_visitor): Always reduce "a M b"
to "a & b" if "a" is a pure eventual formula, remove the
constraint on "b".
* src/ltltest/reduccmp.test: Add two tests.
* iface/dve2/dve2.hh (load_dve2): Take a "dead" argument.
* iface/dve2/dve2.cc (callback_context): Add a destructor
to simplify...
(dve2_succ_iterator::~dve2_succ_iterator) ... this one.
(convert_aps): Skip the dead proposition.
(dve2_kripke::dve2_kripke): Take a dead argument, and
setup alive_prop and dead_prop.
(compute_state_condition, get_succ): Use a cache for the
conditions and successor of the last state, to share
some work between these two function. Add loops on dead
states.
(load_dve2): Pass dead to dve2_kripke and convert_aps.
* iface/dve2/dve2check.cc: Add a -dDEAD option.
* iface/dve2/finite.test, iface/dve2/finite.dve: New file.
* iface/dve2/Makefile.am: Declare them.
Suggested by Yann Thierry-Mieg.
* iface/dve2/dve2.cc (convert_aps): Allow string on the right
of operators, and look them up.
* iface/dve2/dve2check.test: Test this syntax.
* iface/dve2/dve2.cc (compile_dve2): New function. Compile
the *.dve source if there is no newer *.dve2C already.
(load_dve2): Call compile_dve2 when given a *.dve file.
* iface/dve2/dve2.hh (load_dve2): Document it.
* src/ltlparse/ltlscan.ll: Do not recognize `.' as an AND. Allow
it in atomic propositions.
* src/evtgbaparse/evtgbascan.ll, src/tgbaparse/tgbascan.ll: Accept
`.' in identifiers.
* src/misc/bareword.cc (is_bareword): Accept `.' inside
barewords, so that there is no need to quote `X.Y'.
* src/ltltest/parse.test: Do not use `.' as and operator..
