This follows up on a mail from Sonali Dutta.
* src/tgba/bdddict.hh (assert_emptiness, ~bdd_dict): Better
documentation.
* src/tgba/formula2bdd.hh (formula_to_bdd): Mention
unregister_all_my_variables().
(bdd_to_formula): Complete the documentation.
* THANKS: Add Sonali Dutta.
* bench/emptchk/formulae.ltl: Do not use + and * in the list of
formulas. Use | and & instead. The * operator was removed on
2010-01-30. Reported by Étienne Renault.
Especially with should write !(p0) and not !p0, because p0 is
usually #define'd by the user and he may have forgotten to quote
the value of the macro. This issue was discovered by Kristin
Yvonne Rozier and diagnosed by Gerard Holzmann.
* src/tgbaalgos/neverclaim.cc (process_link): Call
to_spin_string(..., true) to fully parentheses the string.
* src/tgbatest/neverclaimread.test: Add a test.
* src/tgba/tgbasafracomplement.cc
(tgba_safra_complement::tgba_safra_complement)
(tgba_safra_complement::succ_iter): Correct the declaration and
use of multiple acceptance conditions.
(state_complement::to_string): Output the L set, not U. The previous
code caused different states to share the same names, causing issues
with the text-based output (state with identical names get merged).
* src/tgba/tgbasafracomplement.hh
(tgba_safra_complement::acceptance_cond_vec_): Adjust type to
store BDDs.
* src/tgbatest/complementation.cc: Implement a new "-b" option
to output automata in Spot's syntax.
* src/tgbatest/complementation.test: Add a test-case supplied
by Martin Dieguez Lodeiro.
* THANKS: Add Martin.
Reported by Tomáš Babiak <xbabiak@fi.muni.cz>.
* src/tgba/tgbatba.cc (tgba_tba_proxy): Replace the std::map used
to record outgoing transitions by an Sgi::hash_map, and keep the
order of these transitions in a separate list.
* src/tgbatest/degendet.test: New file.
* src/tgbatest/Makefile.am (TESTS): Add it.
* THANKS: Add Tomáš and convert to utf8.
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>.
* src/tgba/tgbasafracomplement.hh (safra_tree_automaton): Do not
forward declare.
(tgba_safra_complement): Use void* instead of
safra_tree_automaton*.
* src/tgba/tgbasafracomplement.cc: static_cast void* to
safra_tree_automaton* anywhere needed.
* 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
Rdiger Ehlers.
