2010-01-21  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	Speedup reduc.test by not spawning one process per formula.

	* src/ltltest/reduc.cc: Add an option -f to read a lost of
	formulae from a file.  Running a process for each formula was
	too slow.  Also add an option -h to hide reduced formulae.
	* src/ltltest/reduc.test: Simplify accordingly.

	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.
	* src/tgbatest/emptchk.test: Add the troublesome graph as
	test case.

	When iterating a hash_map, be careful not to delete i->first
	before doing ++i to avoid memory issues.

	* src/tgba/taatgba.cc, src/tgba/taatgba.hh,
	src/tgba/tgbaexplicit.cc, src/tgba/tgbaexplicit.hh: Fix them.

	Minor fixes to compile with GCC 3.3

	* src/ltlast/automatop.cc, src/ltlast/automatop.hh: Rename nfa as
	get_nfa to avoid a name clash with the `nfa' class.
	* src/ltlvisit/clone.cc, src/ltlvisit/nenoform.cc,
	src/ltlvisit/tostring.cc, src/tgbaalgos/eltl2tgba_lacim.cc: Use
	get_nfa instead of nfa.

	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.

	Introduce taa_tgba_labelled<label> so that we can build
	taa_tgba instances labelled by other objects than strings
	in the same way Alexandre did for tgba_explicit.

	* src/tgba/taatgba.cc, src/tgba/taatgba.hh: Split taa_tgba in two
	levels: taa_tgba with no label and taa_tgba_labelled templated by
	the type of the label.  Define taa_tgba_string (with the interface
	of the former taa_tgba class) and taa_tgba_formula for future use
	in ltl2taa.cc.
	* src/tgbaalgos/ltl2taa.cc, src/tgbatest/taatgba.cc: Adjust to use
	taa_tgba_string.

	extended LTL instead of an LTL, a feature previously offered by
	eltl2tgba.cc. Also: -R3b to use delete_unaccepting_scc.

	any simulation-based reduction.

2009-11-13  Alexandre Duret-Lutz  <adl@lrde.epita.fr>

	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.
	* src/ltlast/atomic_prop.cc, src/ltlast/atomic_prop.hh,
	src/ltlast/automatop.cc, src/ltlast/automatop.hh,
	src/ltlast/binop.cc, src/ltlast/binop.hh, src/ltlast/constant.cc,
	src/ltlast/constant.hh, src/ltlast/multop.cc,
	src/ltlast/multop.hh, src/ltlast/unop.cc, src/ltlast/unop.hh:
	Empty the constructor (do not precompute the dump_ anymore),
	and add a dump() implementation.

	that we can find options without resorting to grep...  Also
	cleanup the program name if it is a libtool wrapper.

	(opt_fm, opt_taa): Replace these two variables by ...
	(translation): ... this enum.  And use a switch to call the
	correct translation.

	Use tgba_explicit_formula instead of tgba_explicit_string in FM.

	This gives a nice speedup (>1.4) in the ltlcounter benchmark,
	because we no longer have to generate a copy the string
	representations of the LTL formulae.

	* src/tgbaalgos/ltl2tgba_fm.cc: Adjust.  Also get rid of the
	formulae_seen map, since we can now ask the tgba_explicit_formula
	if it knows the state.

	Change the way references are counted to speedup cloning.

	Before this patch, every time you cloned a formula, the clone
	visitor would recurse into the entire AST to increment the
	reference count of all nodes.  When running ltl2tgba_fm on
	the formula generated by "LTLcounterLinear.pl 8", approx 27% of
	the time was spent in the clone visitor.

	After this patch, cloning a formula is just an increment of the
	reference count of the top node.  Children are decremented only
	when the top node's ref count is decremented to zero.  With this
	change, clone() and destroy() become constant time, the
	ltl2tgba_fm spend only 0.01% of the time cloning formulae.


	* src/ltlast/automatop.cc (~automatop): Decrement children.
	(instance): Decrement children if the instance already exists.
	* src/ltlast/binop.cc, src/ltlast/multop.cc, src/ltlast/unop.cc:
	Likewise.
	* src/ltlvisit/clone.cc (clone): Simplify, now we only need to
	call ref().
	* src/ltlvisit/destroy.cc (destroy): Simplify, now we only need
	to call unref().
	(destroy_visitor): Remove, no longer needed.

	Number states using negative values and SCCs using nonnegative
	values.

	Before this change states were numbered using positive values and
	SCCs using negative values.  That meant the user had to work with
	negative values.  With this changes, the nonnegative values used
	to label SCCs can also directly be used as index in the scc_map_.

	* src/tgbaalgos/scc.hh (scc_map::scc_of_state,
	scc_map::cond_set_of, scc_map::acc_set_of, scc_map::states_of,
	scc_map::initial, scc_map::scc_type, scc_map::succ,
	scc_map::accepting): Adjust prototypes to take or return unsigned
	arguments.
	* src/tgbaalgos/scc.cc: Adjust prototypes of the above functions.
	(scc_map::build_map, scc_map::relabel_component): Number states
	using negative values, and SCCs using nonnegative values.
	(dump_scc_dot): Adjust to use nonnegative values.

	Store the scc_map_ as a vector instead of a std::map.  There is no
	point in using a map since the SCC are numbered in sequence.

	* src/tgbaalgos/scc.hh (scc_map::relabel_component): Return the
	number of the SCC instead of taking it as argument.
	(scc_map::scc_num_): Delete this variable.  scc_map_.size() gives
	the same information.
	(scc_map::scc_map_type): Define using std::vector instead of
	std::map.

	Add support for ELTL (AST & parser), and an adaptation of LaCIM
	for ELTL.

        * configure.ac: Adjust for src/eltlparse/ and src/eltltest/
	directories, and call AX_BOOST_BASE.
	* m4/boost.m4: New file defining AX_BOOST_BASE([MINIMUM-VERSION]).
	* src/Makefile.am: Add eltlparse and eltltest.
	* src/eltlparse/: New directory.  Contains the ELTL parser.
	* src/eltltest/: New directory.  Contains tests related to
	ELTL (parser and AST).
	* src/ltlast/Makefile.am: Adjust for ELTL AST files.
	* src/ltlast/automatop.cc, src/ltlast/automatop.hh: New files.
	Represent automaton operators nodes used in ELTL ASTs.
	* src/ltlast/nfa.cc, src/ltlast/nfa.hh: New files.  Represent
	simple NFAs used internally by automatop nodes.
	* src/ltlast/allnode.hh, src/ltlast/predecl.hh,
	src/ltlast/visitor.hh: Adjust for automatop.
	* src/ltlvisit/basicreduce.cc, src/ltlvisit/clone.cc,
	src/ltlvisit/clone.hh, src/ltlvisit/contain.cc,
	src/ltlvisit/dotty.cc, src/ltlvisit/nenoform.cc,
	src/ltlvisit/postfix.cc, src/ltlvisit/postfix.hh,
	src/ltlvisit/reduce.cc, src/ltlvisit/syntimpl.cc,
	src/ltlvisit/tostring.cc: Because LTL and ELTL formulae share the
	same class hierarchy, LTL visitors need to handle automatop nodes
	to compile.  When it's meaningful the visitor applies on automatop
	nodes or simply assert(0) otherwise.
	* src/tgba/tgbabddconcretefactory.cc (create_anonymous_state),
	src/tgba/tgbabddconcretefactory.hh (create_anonymous_state): New
	function used by the LaCIM translation algorithm for ELTL.
	* src/tgbaalgos/Makefile.am: Adjust for eltl2tgba_lacim* files.

	src/tgbaalgos/eltl2tgba_lacim.hh: New files.  Implementation of
	the LaCIM translation algorithm for ELTL.
	* src/tgbaalgos/ltl2tgba_fm.cc, src/tgbaalgos/ltl2tgba_lacim.cc:

	Update parsers to work with Bison 2.4.1.

	* HACKING: Mention that we require Bison >= 2.4 for developers.
	* src/evtgbaparse/evtgbaparse.yy, src/tgbaparse/tgbaparse.yy,
	src/ltlparse/ltlparse.yy: The sections "%{ ... %}" should now be
	renamed "%code requires { ... }" or "%code { ... }" depending on
	whether they should end up in the parser's header file or its cc
	file.  Also use %language, %locations, %defines, instead of
	command-line arguments.
	* src/evtgbaparse/Makefile.am, src/tgbaparse/Makefile.am,
	src/ltlparse/Makefile.am: Remove the --locations, --defines
	and --languages in the call to bison.  Add -Wall -Werror to
	catch more errors.

	Reorganize this function so that syntactically there is only one

	suppress that to index_and_insert introduced on 2004-12-29.  Also
	split the "group" option in two: "group" and "group2".  "group2"
	is the equivalent of the older "group", while the new "group" is
	weaker and faster.
