	* spot/twaalgos/genem.cc: In the spot29 implementation for the generic
	case, when Fin(fo)=true and Fin(fo)=false have to be tested
	separately, the second test can be done by a loop instead of a
	recursion, to avoid unnecessary processing of the acceptance
	condition.  Suggested by Jan Strejček.

2020-07-13  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	ltldo: improve error messages

	Use ltldo:... instead of error:... and warning:... and also improve
	the diagnostic displayed after a translation failure to mention the
	tool and formula.

	Incidentally, this fixes a spurious test case failure observed by
	Philipp Schlehuber on CentOS7.7 where glibc 2.17 is installed.  With
	this system, when posix_spawn() starts a binary that does not exist,
	it returns success and let the child die with exit code 127.  On more
	recent glibc, posix_spawn() manages to return execve()'s errno, as if
	the child had not been created.  We handle those two different ways to
	fail, but before this patch one used to print "error:..." and the
	other "ltldo:...".

	* bin/ltldo.cc: Display the program_name in error message.  Display
	the command name and formula on translation failure.
	* tests/core/ltldo.test: Adjust test case.
	* NEWS: Mention the fix.

2020-07-13  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	simplify_acc: perform unit-propagation earlier

	Closes #405.   This shows no difference on the test suite,
	but that is thanks to the previous patch: without it, an
	example in automata.ipynb would have an extra edge.

	* spot/twaalgos/cleanacc.cc (simplify_acceptance): Call
	unit_propagation() before simplify_complementary_marks_here() and
	fuse_marks_here(), because that is simpler to perform.

	* tests/python/automata.ipynb, tests/core/remfin.test: Improve
	expected results.
	* NEWS: Mention the bug.

2020-07-13  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

2020-07-13  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	stats: speed up the computation of transitions

	Juraj Major reported a case with 32 APs where ltlcross would take
	forever to gather statistics.  It turns out that for each edge,
	twa_sub_statistics was enumerating all compatible assignments of 32
	APs.  This uses bdd_satcountset() instead, and also store the result
	in a long long to avoid overflows.

	* spot/twaalgos/stats.cc (twa_sub_statistics): Improve the code for
	counting transitions.
	* bin/common_aoutput.hh, bin/ltlcross.cc, spot/twaalgos/stats.hh:

	instantiated only once.

2020-04-17  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	to_parity: only call reduce_parity() when prefix_parity is enabled

	Calling reduce_parity() in to_parity() is confusing, because then
	running to_parity() on one SCC does not necessarily produce the same
	output as running to_parity() on the entire automaton.  However it is
	necessary for the implementation of parity_prefix.  As a compromise,
	disable reduce_parity() when parity_prefix is disabled, this way we
	can use that to demonstrate how the algorithm works.

	call reduce_parity() when parity_prefix is disabled.

	improve partial_degeneralize() on several cases

	On these 4 cases, added to pdegen.py, and supplied by Florian Renkin,
	partial_degeneralize() is now at least as good as degeneralize_tba(),
	and sometimes better.  This is achieved as follows: (1) a
	propagate_marks procedure is introduced to propagate marks as far as
	possible on the automaton (e.g., common outgoing marks can be push
	onto the incoming transitions and vice-versa), (2) the
	degeneralization order is compute dynamically, and (3) whenever and
	fully-accepting transition is taken in the original automaton, the
	destination level is chosen to be the highest existing level.

	* spot/twaalgos/degen.cc,
	spot/twaalgos/degen.hh (propagate_marks_vector, propagate_marks_here):

	forbid the use of std::endl on std::cerr

	std::cerr will flush after each operator<< by default, so it's simpler
	to use \n instead of std::endl, especially if we can merge \n into the
	previous string.  Ideally we should prefer \n for std::cout as well,
	but there are reasonable cases where we want to call std::endl there,
	so it's hard to enforce.

	fix and check shifting issue

	wanted them to be active in Python, it was not always the case.

	* spot/twa/acc.hh: introduce max_accsets() as
	a static constexpr method, so we can see it in Python.

	so the check is actually enabled when compiling the Python
	bindings.

	include config.h in all *.cc files

	This helps working around missing C functions like strcasecmp that do
	not exist everywhere (e.g. on Cygwin), and for which lib/ supplies a
	replacement.  Unfortunately we do not have such build in our current
	continuous integration suite, so we cannot easily detect files where
	such config.h inclusion would be useful.  Therefore this patch simply
	makes it mandatory to include config.h in *.cc files.  Including this
	in public *.hh file is currently forbidden.

	Fixes #260.  Reported by František Blahoudek.

	The simplification F(f)|q = F(f|q), where q designates an event_univ
	formula, was not always applied because of a couple of issue: (1) the
	mospliter was ignoring event_univ unless favor_event_univ was set, (2)
	when processing formulas from res_EventUniv they were not put back
	into res_F or res_G to be subject to the F/G rules.

	sccinfo: improve detection of rejecting 1-self-loop SCCs

	As observed in #188, the smaller.hoa automaton is made only of
	1-state/1-self-loop SCCs, for which calling remove_fin is a complete
	waste of time.  This patch alone (i.e., without the other changes
	suggested by #188) improves the run time of

	% autofilt -q --is-unambiguous smaller.hoa

	from 38s to 0.05s.

	* spot/twaalgos/sccinfo.cc: If a single-state SCC has undeterminate SCC
	and only one self-loop, then it is necessarily rejecting.
	* NEWS: Mention the change.

	dot: improve option initialization

	* spot/twaalgos/dot.cc: Rearrange options to speed up their
	initialization and avoid an "uninitialized read" error from valgrind
	when compiling with clang-3.9.  The uninitialized read is still a bit
	misterious to me; valgrind was complaining about opt_shape_ who is
	actually initialized in the code.  However looking into the assembly
	code generated revealed that all consecutive 0/false values were
	initialized together, so this patch reorganize the options to encourage
	that.  Also the palette was copied over for each call to print_dot(), so
	this is now declared statically.

	Work around weird Python 3.5 generator/iterator interaction

	* wrap/python/spot.py: Python 3.5 reports some unexpected SystemError
	messages when the stack of iterator(...(iterator(generator))) we build
	for random LTL generation raises a StopIteration.  The messages are
	attached either to delete_formula or delete_randltlgenerator, claiming
	that these functions exit with an error; but I have checked that they
	do not.  I've been unable to understand the cause of the issue.
	Replacing the generator by an iterator at least fixes the problem in a
	way that is transparent for our API.

	* src/twaalgos/postproc.hh: Allow the formula not to be specified.  The
	code already support that, as it is called with an explicit nullptr in

	Python bindings.

	revamp the formula hierarchy (montro-patch)

	Flatten the formula ltl::formula hiearchy into a single ltl::vnode that
	has an enumerator to distinguish the types of node, and a common
	interface to access children, update reference counts, etc.  The
	ltl::formula class is now a thin wrapper around an ltl::vnode pointer to
	keep track of reference counts automatically.  Visitor are not used
	anymore; we now have map() and traversor() methods that are more
	concise.

	This basically fixes #43, but should be followed by some fine tuning
	that should now be localized to the formula.hh and formula.cc files.

	Some statistics about this patch.  I started working on it on Sep 9, had
	a first compiling version two weeks later on Sep 22, and it then took 5
	days to fixes the ~70 distincts bugs that were introduced during the
	conversion.  About 13200 lines were modified, and one third of those
	were removed.

	ltlvisit: rename tostring.hh as print.hh and rename printer functions

	This actually performs three related changes, but separating them
	would be quite inconvenient.

	1) rename tostring.hh to print.hh a welcome side-effect is that
	I could fix several files that included this file for not reason.

	2) de-overload some of the to_string functions, and rename them
	as follow:

	  to_string -> print_psl, print_sere, str_psl, str_sere
	  to_utf8_string -> print_utf8_psl, print_utf8_sere,
	                    str_utf8_psl, str_utf8_sere
	  to_spin_string -> print_spin_ltl, str_spin_ltl
	  to_wring_string -> print_wring_ltl, str_wing_ltl
	  to_lbt_string -> print_lbt_ltl, str_lbt_ltl
	  to_latex_string -> print_latex_psl, str_latex_psl
	  to_sclatex_string -> print_sclatex_psl, str_sclatex_psl

	Now it is clearer what these functions do, and their restrictions.

	3) all those print_* functions now take the stream to write onto
	as their first argument.  This fixes #88.

	* src/ltlvisit/tostring.cc, src/ltlvisit/tostring.hh: Rename into...
	* src/ltlvisit/print.cc, src/ltlvisit/print.hh: ... those, and make
	the changes listed above.

2015-05-18  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	sat-minimize: ignore silly histories

	If the target acceptance is Fin(0)&Inf(1), there is no need to
	distinguish between an history of {0,1} and an history of {0}, as a
	cycle with either history will be rejected.  This implements this
	simplification.  If both the canditate and reference automata
	are Rabin automata with n pairs, then we now use at most
	  Q * Q' * Q * Q' * 3^n * 3^n
	variables to encode the partial cycles histories, versus
	  Q * Q' * Q * Q' * 4^n * 4^n
	before.

2015-05-18  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	sat-minimize: omit impossible histories

	When the reference acceptance condition is complex enough, some
	accepting SCCs may not use all acceptance sets.  In that case
	we don't have to encode all possible histories for this SCC.

	* src/twaalgos/dtgbasat.cc: Improve the encoding by omitting
	histories involving sets that are not used in a reference SCC.

	postproc: add a SBAcc option

	Producing state-based acceptance is now part of the postprocessing
	routines.  That means we can more easily simplify automata with
	state-based acceptance (using autfilt -S --small --high, for instance)
	and as as side-effect, ltl2tgba can produce GBA.  However the result of
	ltl2tgba -S is often larger than that of ltl2tgba -B.

	* src/twaalgos/postproc.cc, src/twaalgos/postproc.hh: Implement
	the SBAcc option.
	* src/bin/common_post.cc, src/bin/common_post.hh: Implement -S.

	rename the spot::tgba class as spot::twa

	Now that we support any type of omega-accetpance, not just "Generalized
	Büchi", it is time to move away from GB and replace it by "ω", written
	just w in ASCII.

	This just change the name of the tgba class.  This part has to be done
	by hand because the word "tgba" occurs in many contexts and a mass
	replacement would be wrong.

	This will be followed by some automatic renaming of all the derived
	types and more.

	hoaparse: also accept LBTT input

	This is probably the worse grammar I wrote: the LBTT format is designed

	ltl2tgba_fm: fix non-deterministic output

	The ltl_to_tgba_fm() translation function was using a hash_map of
	maps (ugh!) to merge transitions on output.  However recent libstd++
	changed the implementation of hash_map (a.k.a. unordered_map) causing
	transitions to be output in a different order.  This
	implementation-dependent order caused the ltl2ta.test to fail because
	the BA->TA transformation can produce TA of different sizes if you
	simply change the order of transitions in the input BA! This does not
	sound like a nice property for the BA->TA transformation, but Ala Eddine
	isn't sure how to fix it yet.  In the meantime, this patch makes sure
	ltl_to_tgba_fm() will return the same output regardless of the
	implementation of hash_map.

	The ltl2ta.test failure has been observed with g++ 4.9.2 on Arch Linux,
	and with gcc-snapshot (5.0.0 20141016) on Debian.

	* src/tgbaalgos/ltl2tgba_fm.cc: Rewrite the transition merging

	Replace most uses of scc_map by scc_info.

	ltlcross: adding option --grind=FILENAME

	Suggested by Joachim Klein.

	When a bogus formula is found by ltlcross, the --grind=FILENAME option
	tries to find a smaller formula for which the bug is still present, and

	Store membership to acceptance sets using bitsets, not BDDs.

	This is a huge patch, that took over a month to complete.  The bit sets
	are currently restricted to what 'unsigned can store', but it should be
	easy to extend it to 'uint64_t' should we need it.

	* NEWS: Update.
	* src/tgba/acc.hh: New file.
	* src/tgbatest/acc.cc, src/tgbatest/acc.test: Test it.
	* src/tgba/tgbakvcomplement.cc, src/tgba/tgbakvcomplement.hh,
	src/tgba/tgbasgba.cc, src/tgba/tgbasgba.hh: Delete.  The KV
	complementation is too slow to be used in practice, and I somehow broke
	it during the conversion to bitsets.  The tgba->sgba conversion was only
	used for the KV complementation, and should be better redone on
	tgba_digraph_ptr should it be needed again.

	Handle all automata through shared_ptr.  (monstro patch)

	A type such as 'const tgba_digraph*' and 'tgba_digraph*' are replaced
	by 'const_tgba_digraph_ptr' and 'tgba_digraph_ptr'.  Additionally 'new
	tgba_digraph(...)' is replaced by 'make_tgba_digraph(...)'.

	This convention is followed by all automata types. Those smart
	pointers should normally be passed by const reference as input of
	function to avoid the atomic increments/decrements, but I probably
	missed a few, as this huge patch took me nearly 12h.

	replace sba_explicit_* by tgba_digraph, and use tgba_digraph is postproc

	This is a huge patch.  tgba_digraph are equiped with some boolean
	properties that can be used to indicate whether they represent SBA
	(and will carry more informations later).  All algorithms that produce
	or use sba_explicit_* automata are changed to use tgba_digraph.
	postproc has been rewritten using only tgba_digraph, and this required
	changing the return types of many algorithms from tgba* to
	tgba_digraph*.

	Remove ltl2tgba_lacim and all supporting classes.

	This translator algorithm is seldom used in practice because we work
	with explicit automata everywhere, and this is only useful to build
	symbolic automata.  Furthermore, the symbolic automata produced by this
	algorithm are larger (when looked at explicitly) than those produced by
	ltl2tgba_fm or other explicit translators.

	The nice side effect of this removal is that we can also remove a lot of
	supporting classes, that were relying a lot on BDDs.

	and other constant member initialization.

2013-07-28  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	Fix interpretation of {e[*]} and !{e[*]}.

	This follows from a discussion with Ernesto Posse.

	The semantics for the {...} operator we use in Spot comes from the
	cl(...) operator defined by Dax et al. (ATVA'09).  This is slightly
	different from the the way the PSL spec interprets a SERE used in the
	context of a temporal formula (appendix B.3.1.1.2, item 7).

	cl({a;b}[*]) would match any infinite word that starts with a;b, while
	in PSL {a;b}[*] would match any infinite word that alternates a and b.

	Spot documents that {SERE} in a temporal formula is interpreted like
	cl(SERE) however it failed to ignore the empty prefix of SERE.  So
	{{a;b}[*]} would match anything, because the empty word is a prefix of
	any word, and is also accepted by {a;b}[*].  Some trivial identities
	and basic rewritings were also wrongly considering these empty
	prefixes as well.

	This patch therefore fixes the translation and syntactic
	simplification rules, to really ignore these empty prefixes.

	In some future version it should probably be wise to rename this {...}
	operator as cl(...), and use {...} for the semantics given in appendix
	B.3.1.1.2 (item 7) of the PSL specs.

	* src/ltlast/unop.cc: Fix trivial identities.  We have
	{[*0]} = 0 and !{[*0]} = 1.
	* src/ltlvisit/simplify.cc: Fix basic rewriting rules.
	{e[*]} = {e} and !{e[*]} = !{e}.
	* doc/tl/tl.tex: Adjust documentation.
	* doc/tl/tl.bib (dax.09.atva): New entry.
	* src/tgbaalgos/ltl2tgba_fm.cc: Do not accept any
	infinite word for {e[*]} just because the empty
	prefix is matched by e[*].
	* src/tgbatest/ltl2tgba.test: Add a test case.
	* NEWS: Mention it.
	* THANKS: Add Ernesto.

	neverpase: fix parsing of neverclaim produced by ltl2ba and ltl3ba

	These translator may output guards such as (a) || (b), but with the
	changes in Spot 1.1.3 it would only work with ((a) || (b)).

	Furthermore when ltlcross would fail to parse a neverclaim containing
	such a guard, it would fail to parse all later neverclaims, because
	the lexer was not properly reset.

	* src/neverparse/neverclaimscan.ll: Scan (a) || (b) as a single
	token.
	(neverclaimyyopen): Reset the lexer.

	automata since they are known from the scc.  Avoid several dynamic

	Implement a favor_even_univ option in the rewriting rules.

	The set of rules enabled by favor_even_univ try to "lift" the
	subformulae that are both eventual and universal, so they appear
	higher in the AST.  This is contrary to what we used to do (and still
	do when the option is unset), were we try to postpone such subformulae
	(by moving them down the AST).  It is still a bit experimental.

	fix a memory leak in basic LTL simplifications

	When something like XFa & FXa is reduced, the subformulae XFa and FXa
	are both rewritten separately to XFa, and then the vector of arguments
	of the And operators, [XFa,XFa], is passed through a specialized loop
	that searches of the form X(...) that can potentially be simplified with
	some other terms.  This loop converts the vector [XFa,XFa] into the set
	{XFa,XFa}={XFa} and forgot to deal with the case where the insertion
	would actually not add an existing subformula.

	* src/ltltest/Makefile.am (TESTS): Add it.

	ltlparse: add a lenient parsing mode

	Spin 6 supports formulas such as []<>(a < b) so that atomic properties
	need not be specified using #define.  Of course we don't want to
	implement all the syntax of Spin in our LTL parser because other tools
	may have different syntaxes for their atomic propositions.  The
	lenient mode tells the scanner to return any (...), {...}, or {...}!
	block as a single token.  The parser will try to recursively parse
	this block as a LTL/SERE formula, and if this fails, it will consider
	the block to be an atomic proposition.  The drawback is that most
	syntax errors will no be considered to be atomic propositions.  For
	instance (a U b U) is a single atomic proposition in lenient mode, and
	a syntax error in default mode.

	* src/ltlparse/ltlparse.yy, src/ltlparse/ltlscan.ll,
	src/ltlparse/parsedecl.hh, src/ltlparse/public.hh: Add a
	lenient parsing mode.  Simplify the lexer using yy_scan_string.

	Fix a memory leak on failure to WDBA-minimize.

	* src/tgbaalgos/minimize.cc (minimize_obligation): Delete the powerset
	automaton when we return 0 because we know if the result is correct

2012-06-04  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	Rework the timeout of the CGI script.

	The previous implementation was fine to catch timeout of third-party
	tools (like dot), but to good to catch timeout in Spot itself, because
	Python will not deliver a SIGALRM while a native function (e.g. Spot's
	translation) is running.  So we fork() the Python process, with a
	parent that does nothing but wait for the termination of the child or
	for an alarm.  On SIGALRM, the parent kills all children.

	* wrap/python/ajax/spot.in: Adjust to fork.
	* wrap/python/tests/alarm.py: New test file to test this
	scenario in a more controled environment.
	* wrap/python/tests/Makefile.am: Add it.

2012-05-22  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	Make it easier to convert acc-conditions to associated formulae.

	This is motivated by the fact that sog-its used the low-level data
	structures used by the bdd_dict to do such work, and broke because of
	the recent changes in this area.

	* src/tgba/bdddict.cc, src/tgba/bdddict.hh (oneacc_to_formula):
	New method.
	* src/tgbaalgos/save.cc: Use it.

2012-05-22  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	* NEWS: Summarize recent changes.

2012-05-21  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	Clear the contaiment cache after -r7.

	Doing so will release all BDD variables used by automata created for
	syntactic implication.  This way the main translation will create
	acceptance variables again in a more natural order, which will help
	the degeneralization (until we get a better degeneralization).

	* src/ltlvisit/contain.cc, src/ltlvisit/contain.hh
	(language_containment_checker::clear): New method to clear the
	containment cache.
	* src/ltlvisit/simplify.cc, src/ltlvisit/simplify.hh
	(clear_as_bdd_cache): Also call language_containment_checker::clear.

2012-05-21  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	Use the distributed LBTT is the installed one is not 1.2.1a.

	* m4/lbtt.m4: Check version number.

2012-05-21  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	Adjust parseout.pl to the new LBTT output.

	* bench/ltl2tgba/parseout.pl: Adjust to output nondeterministic
	indices and number of nondeterministic automata.
	* bench/ltl2tgba/README: Update explanations.

2012-05-20  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	FM: Simplify promises of U, M, and F formulae.

	* src/tgbaalgos/ltl2tgba_fm.cc (translate_dict::register_a_variable):
	Simplify promises by replacing P(a U b), P(b M a), and P(Fb), by P(b).

2012-05-20  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	ltl2tgba: Set assume_sba for automata read from a neverclaim.

	This cause double-circles for accepting states in dot output.

	* src/tgbatest/ltl2tgba.cc: Set assume_sba for automata read from
	neverclaims.  Reset assume_sba after scc_filter and simulation.
	* src/tgbatest/neverclaimread.test: Expect a double circle.

2012-05-20  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	Clean the as_bdd() cache after LTL simplification.

	Syntactic implication checks may use as_bdd() to compare Boolean
	formulae.  By doing so, they register Boolean variables in an order
	that is usially detrimental to the LTL translator.  The new,
	clear_as_bdd_cache() function offers a mean to unregister these
	variables, so that the LTL translator will register them again in the
	a more natural way.

	* src/ltlvisit/simplify.hh, src/ltlvisit/simplify.cc
	(clear_as_bdd_cache): New function.
	* src/tgbatest/ltl2tgba.cc, wrap/python/ajax/spot.in: Call it.

2012-05-20  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	Speedup syntactic implication by not comparing literals using bdd.

	* src/ltlvisit/simplify.cc
	(ltl_simplifier_cache::syntactic_implication): If the lhs and rhs are
	literals that are not equal, return false immediately.

2012-05-20  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	Add -rD option to ltl2tgba, to display some caching statistics.

	* src/ltlvisit/simplify.cc, src/ltlvisit/simplify.hh (print_stats):
	New function.
	* src/tgbatest/ltl2tgba.cc: Call it.

2012-05-20  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	Correctly handle ltl2tgba's option -rL.

	* src/tgbatest/ltl2tgba.cc: Fix mismatch between the help text,
	documenting -rL, and the handling code, expecting -rs.

2012-05-20  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	FM: use a vector to store the Next BDD->formula map.

	* src/tgbaalgos/ltl2tgba_fm.cc: Here.

2012-05-20  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	Overhaul bdddict to speedup bdd->formula lookups.

	* src/tgba/bdddict.hh, src/tgba/bdddict.cc: Store variable types and
	associated formula in a vector indexed by BDD variable numbers,
	instead of using several maps.
	* src/evtgbaalgos/tgba2evtgba.cc, src/tgba/bddprint.cc,
	src/tgba/formula2bdd.cc, src/tgbaalgos/ltl2tgba_fm.cc,
	src/tgbaalgos/save.cc: Adjust usage.

2012-05-14  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	FM: collect implied formulae in & arguments; do not to translate them

	* src/tgbaalgos/ltl2tgba_fm.cc (implied_subforfmulae): New function.
	(ltl_trad_visitor::visit(const binop*)): Use it.  This is an attempt
	to correct the unoptimal translation of 'Fa & GFa' left by previous
	patch.  It still fails to optimize 'Fa & GF(a&b)', but this is not a
	regression compared to previous version.

2012-05-14  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	Faster translation of GFa.

	* src/tgbaalgos/ltl2tgba_fm.cc: Add a "recurring" mode for the
	translation of the child of G.  This generalizes Couvreur's original
	trick to translate GFa as (a|Prom(a))&X(GFa) without generating an
	intermediate GF(a)&F(a) state that would have to be merged with GF(a)
	latter.  This implementation will also speedup formulas such a G((a U
	b) & (c M d)).  With this patch, translating GF(p1) & GF(p2) &
	... GF(p20) into a TGBA takes 57s instead of 128s on my computer.
	However it alsos causes some formulas to be translated into larger
	automata that are not immediately reduced (the simulation-reduction is
	needed).  For instance Fa & GFa now has a different signature than
	GFa, so translating 'Fa & GFa' generates two states where is used to
	generate only one.

2012-05-12  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	Fix translation of !{r}.

	We need a marked version of !{r} to perform breakpoint unroling.

	* src/ltlast/unop.cc, src/ltlast/unop.hh: Declare a NegClosureMarked
	operator.
	* src/ltlvisit/mark.hh, src/ltlvisit/mark.cc,
	src/tgbaalgos/ltl2tgba_fm.cc: Adjust to deal with NegClosureMarked
	and NegClosure as apropriate.
	* src/ltlvisit/simplify.cc, src/ltlvisit/tostring.cc,
	src/ltlvisit/tunabbrev.cc, src/tgbaalgos/eltl2tgba_lacim.cc,
	src/tgbaalgos/ltl2taa.cc, src/tgbaalgos/ltl2tgba_lacim.cc,

	we deal with NegClosure.
	* src/tgbatest/ltl2tgba.test: More tests.
	* src/ltltest/kind.test: Adjust.
	* doc/tl/tl.tex: Mention the marked negated closure.

	* NEWS: Typo in date.

2012-05-07  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	Fix mismatch between srand/srand48 and rand/rand48.

	Because only the configure macros of spot::srand() had been updated to
	the introduction of _config.h, rand() was used even if drand48() was
	available, and yet srand48() was being called by spot::srand().  The
	consequence is that setting the seed with srand48() had not effect on
	the value returned by rand().  Reported by Etienne Renault.

	* src/misc/random.cc (drand): Fix configure macros used.

2012-05-07  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

2012-05-02  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	Use 'const formula*' instead of 'formula*' everywhere.

	The distinction makes no sense since Spot 0.5, where we switched from
	mutable furmulae to immutable formulae.  The difference between
	const_visitor and visitor made no sense either.  They have been merged
	into one: visitor.

	test does not ensure the subformula is ignored early in the
	translation.  I.e., it would still work without the patch.

	Speedup construction of transitions in ltl_to_tgba_fm.

	* src/tgbaalgos/ltl2tgba_fm.cc (ratexp_to_dfa::translate,

	cases.

2012-04-28  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	Setup machinery to build DFA when translating some PSL operators.

	This is especially important when translating the Closure
	operators, because normally we should only keep the satisfiable
	formulae (i.e. co-accessible states), which seems hard to check on
	the fly.  After this patch we need to teach
	ratexp_to_dfa::translate() how to trim (and then minimize) the DFA
