* 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.
Fix some warnings reported by gcc.
* buddy/src/kernel.c (errorstrings): Mark these as const.
* buddy/src/reorder.c (reorder_gbc): Fix prototype.
(siftTestCmp): Add missing const in cast.
(bdd_reorder_auto): Actually call bdd_reorder_ready().
Add support for --enable-devel and similar macros.
* m4/debug.m4: Rename to ...
* m4/bdebug.m4: ... this.
* m4/debug.m4, m4/devel.m4, m4/gccoptim.m4, m4/ndebug.m4: New file.
* m4/gccwarns.m4: Fix usage of cache variable. Fix shell
syntax. Do not check for -Waggregate-return. Update CFLAGS.
* configure.ac: Adjust to handle --enable-devel and similar macros
in the same way as Spot.
* 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.
Tag functions with attributes pure, const, or noreturn.
* src/bdd.h (__purefn, __constfn, __noreturnfn): Define
new macros.
* src/bdd.h, src/bddio.c, src/bvec.h, src/imatrix.h: Use them
to tag many functions as suggested by -Wsuggest-attribute=pure,
-Wsuggest-attribute=const, -Wsuggest-attribute=noreturn.
Remove more sanity checks when NDEBUG is set.
* src/kernel.h (CHECKnc): New macro.
* src/kernel.c (bdd_var, bdd_low, bdd_high, bdd_ithvar,
bdd_nithvar): Use it.
* 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..
