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.
* src/bin/common_finput.cc: Add a --lenient option.
* src/ltltest/lenient.test: New file.
* src/ltltest/Makefile.am: Add it.
* src/neverparse/neverclaimparse.yy: Parse the guards in lenient mode.
* src/tgbatest/neverclaimread.test: Adjust.
* src/ltlvisit/tostring.cc: When outputing a formula in Spin's syntax,
output (a < b) instead of "a < b".
* src/misc/escape.cc, src/misc/escape.hh (trim): New helper function.
* src/misc/formater.hh (formater::format, formater::prime): Move ...
* src/misc/formater.cc: ... in this new file.
* src/misc/Makefile.am: Add it.
* src/sanity/style.test: Allow <iostream> in headers where << or >> are
used.
* src/misc/formater.hh (printable_value): Add more accessors.
* src/bin/ltlcheck.cc: Use the formater class to factor the %-expansion
loop, and reuse filenames (such as %F, %S, and %L) between executions
on the same formula.
* src/misc/unique_ptr.hh: Create unique_ptr for Spot.
* src/misc/Makefile.am: Register this new file.
* src/tgbatest/ltl2tgba.cc: Replace two calls to delete by the
utilisation of unique_ptr.
* src/tgbaalgos/simulation.cc: Replace two calls to delete by the
utilisation of unique_ptr.
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.
* src/misc/acccompl.hh, src/misc/acccompl.cc (AccCompl): Rename to
acc_compl.
* src/tgbaalgos/simulation.cc (AccComplAutomaton, Simulation): Rename
to acc_compl_automaton and direct_simulation. At the same time,
reindent the whole file.
* src/sanity/style.test: Detect capitalized class names.
* src/kripke/kripkeexplicit.hh (KripkePrint): Remove useless
predeclaration.
* src/tgbaalgos/simulation.hh: Typo in comment.
* configure.ac: Check for times() and sys/times.h.
* src/misc/timer.hh: Include sys/times.h conditionally
and use clock() if times() is not available.
Reported by Yann Thierry-Mieg.
* src/misc/acccompl.cc, src/misc/acccompl.hh: Add a way to
an acceptance condition in an automaton, into its
complement.
Create a method to make the reverse operation.
* src/misc/Makefile.am: Add the new files to the compilation.
* src/misc/intvcmp2.cc (stream_compression_base::run): Fix a case
where the "id" of the compression to use would be miscalculated,
causing wrong values to be encoded.
* src/tgbatest/intvcmp2.cc: Add this particular test case.
The previous setup failed with clang++ 3.0.
* m4/stl.m4: New file.
* configure.ac: Call AC_HEADER_UNORDERED_MAP,
AC_HEADER_TR1_UNORDERED_MAP, and AC_HEADER_EXT_HASH_MAP.
* src/misc/hash.hh: Include _config.h, and used the
SPOT_HAVE_UNORDERED_MAP, SPOT_HAVE_TR1_UNORDERED_MAP,
or SPOT_HAVE_EXT_HASH_MAP defines to decide which
file to include.
* src/misc/bddalloc.cc (bdd_allocator::initialize): Call
bdd_setmaxincrease(500000), because the default is 50000,
which cause garbage collection to occur too often.
Spot 0.7.1 used to need 190 acceptance conditions to translate the
188 literature formulae. With this patch we are down to 185.
That's not an impressive, but there are only ~20 formulae that
require more than 1 acceptance conditions; hence little room for
improvement.
* src/misc/bddlt.hh (bdd_hash): New function.
* src/misc/accconv.hh, src/misc/accconv.cc: New files.

* src/tgbaalgos/scc.hh (scc_map::scc::useful_acc): Update description.
* src/tgbaalgos/sccfilter.cc (scc_filter): Simplify acceptance
conditions that are always implied by another acceptance
conditions. Previously, we only removed acceptance conditions
that where always present in accepting SCCs.
* src/tgbatest/sccsimpl.test: New file.
* src/tgbatest/Makefile.am (TESTS): Add it.
