ltihooks.py apparently breaks the import mechanisms of Python 2.6,
causes SWIG's runtime to fail to share a global type table, and
yields various failures in our tests.
* wrap/python/ltihooks.py: Delete.
* wrap/python/Makefile.am (EXTRA_DIST): remove ltihooks.py.
* wrap/python/tests/bddnqueen.py, wrap/python/tests/interdep.py,

wrap/python/tests/setxor.py: Do not use ltihooks.
* wrap/python/tests/run.in (pypath): Include the .libs/ directory
in the search path so that Python can find the *.so libraries.
With this change the output of

uses less than (n+1)^2 transitions when it used
exactly (n+1)*(2^n) transitions before.
* src/tgba/tgbatba.cc (tgba_tba_proxy_succ_iterator): Merge
transitions going to the same states if they are both accepting or
if neither are.
(state_ptr_bool_t, state_ptr_bool_less_than): Helper type to
store a transition in tgba_tba_proxy_succ_iterator.

(tgba_tba_proxy::transition_annotation): Remove. We cannot
implement this method if transitions are merged.

* src/tgbatest/ltl2tgba.cc (syntax, main): Add a -ks option.
* src/tgbatest/ltl2tgba.test, bench/ltlclasses/run,
bench/ltlcounter/run: Use -ks instead of -k to speed things up.
tgba_tba_proxy used to spend a lot of time (re)computing the
acceptance condition common to all outgoing transition of a state.
* src/tgba/tgbatba.hh (accmap_): New cache.
(common_acceptance_conditions_of_original_state): New method.
* src/tgba/tgbatba.cc (tgba_tba_proxy_succ_iterator::~sync)
Call common_acceptance_conditions_of_original_state() instead of
computing the result.

(common_acceptance_conditions_of_original_state): Implement it.
families of LTL formulae.

optional parameter, like for the to_string() function.

handling of full_parent.
(to_spin_string_visitor): Handle full_parent.
reduce_visitor::visit(binop).

Move this method...
(recurse_eu): ... outside as a separate function. Likewise for
the universal/eventual result struct.
(reduce_visitor::visit(binop)): Call recurse_eu() once to replace
two calls to is_eventual and is_universal, thus replacing two
recursions by one.
* src/ltlvisit/syntimpl.cc (eventual_universal_visitor): Use
a union to store the eventual and universal properties as two
bit in a bit-field, and "AND" both of them at once.
(eventual_universal_visitor::recurse_un,
eventual_universal_visitor::recurse_ev): Replace these
two functions by ...
(eventual_universal_visitor::recurse_): ... this one, that
returns both bits as an unsigned.
* src/tgbatest/ltl2tgba.cc (main): Either replay the accepting
run or print it, but do not do both.
* src/tgbatest/emptchk.test: Adjust. I.e. use -C instead of -CR
when we expect the run to be displayed.
* src/tgbatest/randtgba.cc (main): Remove the set but unused opt_A
variable (the upcoming GCC 4.6 would warn about it) and set opt_ec
to 1 if -A is used without -e.
* src/tgbaalgos/reducerun.hh (tgba_run): Predeclare as a struct
since this is what it is.
* src/tgbatest/randtgba.cc (main): Avoid using "i" with two
different type in the same loop.
* src/kripke/fairkripke.hh, src/kripke/fairkripke.cc,
* src/kripke/kripke.hh, src/kripke/kripke.cc: Finalize and
document the Kripke interface. I have tested it by updating
checkpn to use it.

product).

automaton computed, not just the automaton when we degeneralized
it. We may have applied other algorithms since the original
degeneralization.
options -C and -CR for that.
* src/tgbatest/ltl2tgba.cc: Add option -C and -CR to control
whether we want the accepting run to be printed or replayed.

* src/neverparse/neverclaimparse.yy: Accept multiple labels
for the same state. Honor accepting states. Forward parse
error from the parser used for guards. Accept "false" as a
single instruction for a state.

and remove the ";" hack.
* src/tgba/tgbaexplicit.cc
(tgba_explicit_string::~tgba_explicit_string): Adjust not to

in the diagnostics. Use ltl2tgba instead of readsave.
* src/tgbatest/Makefile.am (check_PROGRAMS): Remove readsave.
We do that because the declaration of this type, which is local to
src/tgba/tgbasafracomplement.cc has a member in an anonymous
namespace, and some versions of g++-4.2 issue a very annoying
warning about this legitimate code. See Bug 29365 on GCC's
Bugzilla. Report by Silien Hong <silien.hong@lip6.fr>.
