built output.
This is also a step towards better checks for things like
__attribute__ or std::tr1.
* m4/ax_prefix_config_h.m4: New file.
* configure.ac: Call AC_CONFIG_HEADERS and AX_PREFIX_CONFIG_H.
* src/misc/Makefile.am: Install misc/_config.h.
* src/misc/random.cc, src/misc/version.cc: Include misc/_config.h.
* wrap/python/ajax/ltl2tgba.html: Adjust to use
jQuery 1.6.1 and jQuery-UI 1.8.13. Remove a useless check
of $("#autoupdate").attr("checked") since this checkbox no longer
exists.
* wrap/python/ajax/css/ui-lightness/jquery-ui-1.8.8.custom.css:
Replace by ...
* wrap/python/ajax/css/ui-lightness/jquery-ui-1.8.13.custom.css: This.
* wrap/python/ajax/Makefile.am (EXTRA_DIST): Adjust.
* src/misc/intvcmp2.cc (stream_compression_base::run):
Implement a shift-less encoding for the 1-bit and 3-bit cases.
Also declare offsets as size_t, to help 64-bit compilers.
* 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.
This avoids a library call to bdd_addref or bdd_delref.
* src/kernel.c (bdd_delref_nc, bdd_addref_nc): New function,
that work only on BDD that are not constant.
* src/cpext.cxx (bdd::operator=): Move...
* src/bdd.hh (bdd::operator=): ... here.
(bdd::bdd, bdd::~bdd, bdd::operator=): Inline the "is bdd constant"
check and call bdd_delref_nc/bdd_addref_nc only otherwise.
* 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.
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.
