	implement is_safety_mwdba().

	Note: I swapped the name of safety and guarantee when I
	implemented is_safety_automaton() on 2010-03-20.  Fortunately,
	is_safety_automaton() was only used where is_guarantee_automaton()
	would have been correct.

	Introduce a destroy() method on states, and use it instead of delete.

	Right now, destroy() just executes "delete this".  But in a later
	version, we will rewrite tgba_explicit so that it does not
	allocate new states (and the destroy() method for explicit state
	will do nothing).

	* src/tgba/state.hh (state::destroy): New method, to replace
	state::~state() in the future.

	* src/saba/sabacomplementtgba.cc, src/tgba/tgbakvcomplement.cc:
	Pass shared_state_deleter to the shared_ptr constructor, so that
	it calls destroy() instead of delete.

	Add support for W (weak until) and M (strong release) operators.

	* src/ltlast/binop.cc, src/ltlast/binop.cc: Add support for
	these new operators.
	* src/ltlparse/ltlparse.yy, src/ltlparse/ltlscan.ll: Parse them.
	* src/ltltest/reduccmp.test: Add new tests for W and M.

	Add support for W and M.
	* src/tgbatest/ltl2neverclaim.test: Test never claim output
	using LBTT, this is more thorough.  Also we cannot use -N
	any more in the spotlbtt.test.
	* src/tgbatests/ltl2tgba.cc: Define M and W for ELTL.
	* src/tgbatest/ltl2neverclaim.test: Test W and M, and use
	-DS instead of -N, because lbtt-translate does not want
	to translate these operators for tools that masquerade as Spin.

	appropriate.

	* wrap/python/spot.i (spot::scc_filter): Make it available.

	Use the "full" option unless the show_degen_png or

	* src/ltlparse/ltlparse.yy, src/tgbaparse/tgbaparse.yy,
	src/evtgbaparse/evtgbaparse.yy, src/eltlparse/eltlparse.yy: Use
	token types for %destructor and %printer.  Remove the yylex hack,
	since %name-prefix is now honored by Bison.  Also remove the
	useless <token> type.  Suggested by Akim Demaille.

	Reverse the order of expected acceptance conditions in
	degeneralization.

	* src/tgba/tgbatba.cc (tgba_sba_proxy::tgba_tba_proxy): Build the
	list of acceptance condition in the reverse order.  The order is
	still arbitrary, but the bdd_satone() call seems to output the
	acceptance conditions that are more used first, and this helps the
	degeneralization process.

	"<->" so that "a & b -> c" is interpreted as "(a & b) -> c"
	instead of "a & (b -> c)".  The new interpretation is more
	intuitive, and matches that of LBTT.

	Keep acceptance conditions on transitions going to accepting SCCs
	by default in scc_filter().

	Doing so helps the degeneralization algorithm, because it will
	have more opportunity to be in an accepting level when it reaches
	the accepting SCCs.

	* src/tgbaalgos/sccfilter.cc (filter_iter::filter_iter): Take a
	remove_all_useless argument.
	(filter_iter::process_link): Use the flag to decide whether to
	filter acceptance conditions going to accepting SCCs.
	(scc_filter): Take a remove_all_useless argument and pass it to
	filter_iter.
	* src/tgbaalgos/sccfilter.hh (filter_iter): Add the new argument
	and document the function.
	* src/tgbatest/tgbatests/ltl2tgba.cc (main): Add option use -R3
	for remove_all_useless=false and add -R3f for
	remove_all_useless=true.
	* src/tgbatest/ltl2tgba.test: Show one case where -R3f makes
	the degeneralization worse than -R3.

	* src/ltlvisit/basicreduce.cc (basic_reduce_visitor): Replace
1324
	the FG(a)|FG(b) == F(Ga|Gb) rule by the above more generic one.
1325
1326
1327
1328
	Add the dual rule for G(a)&G(b), as we had none (this one won't

	Better selection of the acceptance of the initial state in SBA.

	* src/tgba/tgbatba.cc (tgba_sba_proxy::tgba_sba_proxy): Set
	cycle_start_ to start in the accepting layer of the degeneralized
	automaton if the initial state has an accepting self-loop.
	Otherwise, starts at the level of the first acceptance condition
	as previously.
	(tgba_sba_proxy::get_init_state): Use cycle_start_.
	* src/tgba/tgbatba.hh (tgba_tba_proxy::a_): Make it protected so
	that we can use it in tgba_sba_proxy::tgba_sba_proxy.
	(tgba_sba_proxy::cycle_start_, tgba_sba_proxy::get_init_state):
	Declare.

	Generalize the previous patch to accepting states in SBA.

	* src/tgba/tgbatba.cc (tgba_tba_proxy_succ_iterator::sync_): Move
	the optimization step added by the previous patch outside the
	before the bddtrue check, so that it also applies to accepting
	states in SBA.

	Optimize tgba_tba_proxy and tgba_sba_proxy for states that share
	an acceptance condition on all outgoing transitions.

1359

	that "ltl2ba -f 'a U (b U c)'" outperformed "ltl2tgba -f -N -R3 'a
	U (b U c)'".  With this change and the previous one, it is no
	longer the case.

	* src/tgba/tgbatba.cc (tgba_tba_proxy_succ_iterator::aut_): Store
	a pointer to the source automaton and...
	(tgba_tba_proxy_succ_iterator::sync_): ... use it in an extra
	optimization step to gather the acceptance conditions common
	to all outgoing transitions of the destination state, and pretend
	they are on the current (ingoing) transition.
	(tgba_tba_proxy::succ_iter): Pass the
	source automaton to the constructed iterator.
	* src/tgbatest/spotlbtt.test: Test -f -N -R3 -r7.
	* src/tgbatest/ltl2tgba.test: Add a test case for 'a U (b U c)'.

2010-03-03  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	ltl2tgba: apply -R3 before -D or -DS.

	* src/tgbatest/ltl2tgba.cc (main): Call scc_filter() before the
	degeneralization, because it might remove useless acceptance
	conditions.  I realized this while looking at experiments from
1382
	Rüdiger Ehlers.

1393
1394

	Fix random_graph() not to generate dead states.

	This is actually the third time I fix random_graph().  On
	2007-02-06 I changed the function not to generated dead states,
	but in a way that made it non-deterministic.  On 2010-01-20 I made
	the function deterministic again, but it started to generate dead
	states as a side effect.  This time, I'm making sure that dead
	states won't come again with a test-case that we should have had
	from the beginning.

	* src/tgbaalgos/randomgraph.cc (random_graph): Add an extra
	indirection array, state_randomizer[], so that we can reorder
	states indices after a random selection without actually changing
	the value of the indices used by unreachable_states and
	nodes_to_process.
	* src/tgbatest/randtgba.test: New file.
	* src/tgbatest/Makefile.am: Add randtgba.test.

	Fix a longstanding bug in our implementation of GV04.

	* src/tgbaalgos/gv04.cc (push): Fix the tracking of the accepting
	link.  This bug was discovered on a random generated graph with
	a complex accepting cycle.

	Remove some non-determinism in random_graph()

	* src/tgbaalgos/randomgraph.cc (random_graph): Revert the part of
	the patch from 2007-02-06 which silently replaced the use of state
	index by state pointers.  Storing states pointer in this map cause
	some non-determinism because of the memory layout.  It was almost
	impossible to reproduce bugs found by tests based on randtgba.

	levels: taa_tgba with no label and taa_tgba_labelled templated by

	of the former taa_tgba class) and taa_tgba_formula for future use

	Replace the hash key construction of LTL formulae by a simple
	counter updated each time we create a new (unique) formula.

	Doing so saves a lot of memory during the translation of the
	ltlcounter formulae, because the formulae are quite big and
	storing a string representation of each formula on its node was a
	bad idea.  For instance with n=12, the translation now uses 40MB
	where it used 290MB.  (Note: in both cases, 20MB is being used by
	the BDD cache.)

	* src/ltlast/formula.hh (hash_key_): Rename as ...
	(count_): ... this.
	(hash): Adjust.
	(max_count): New static variable to count the number of
	formulae created.
	(formula): Update max_count and set count_.
	(dump): Make it a virtual pure method.
	(set_key_): Remove.
	(formula_ptr_less_than): Speed up and return false when
	the two formula pointer are equal.
	* src/ltlast/formula.cc (set_key_, dump): Remove.

	Do not comment states in the never claim by default.  It takes too
	much time when the formula is large, and it is useless when the
	purpose is model-checking with Spin.

	* src/tgbaalgos/neverclaim.hh (never_claim_reachable): Add the
	comments option.
	* src/tgbaalgos/neverclaim.cc (never_claim_bfs,
	never_claim_reachable): Honor the comment option.
	* src/tgba/tests/ltl2tgba.cc (-N): Do not comment states.
	(-NN) New option to output a commented never claim.

	* src/tgbatest/spotlbtt.test: Update TAA related tests.
