* src/ltlast/bunop.hh (one_star): New static method building 1[*].
* src/ltlast/bunop.cc (bunop::~bunop, bunop::instance_count): Adjust.
* src/ltlast/multop.cc: Implement the trivial rewriting.
* src/ltlast/multop.hh, doc/tl/tl.tex: Document it.
* src/ltltest/equals.test: Test it.
Especially, 1&f and 1:f were mistakenly always reduced to f, which is
incorrect when f accept the empty word.
* src/ltlast/multop.cc: Here.
* src/ltlast/multop.hh, doc/tl/tl.tex: Adjust documentation.
* src/ltltest/equals.test: Add more tests.
* src/ltlast/bunop.hh, src/ltlast/bunop.cc, src/ltlvisit/randomltl.cc,
src/ltlvisit/simplify.cc, src/ltlvisit/tostring.cc,
src/tgbaalgos/ltl2tgba_fm.cc: Remove all traces of these two
operators since they are not handled like sugar.
* doc/tl/tl.tex: Adjust documentation to reflect the fact that these
two operators are sugar.
* src/ltlast/multop.hh (is_multop): Take a constant formula as input.
* src/ltlvisit/tostring.cc (to_string_visitor::visit(multop*)):
Output []=> or <>=> when the left argument of a []-> or <>-> is
a concatenation that ends in 1.
* doc/tl/tl.tex: Document this desugaring.
* src/ltlast/multop.hh, src/ltlast/multop.cc (all_but): New method
used to simplify the removal of one element of a multop.
* src/ltlvisit/simplify.cc: Implement the new rewriting rules.
* doc/tl/tl.tex: Document them.
* src/ltltest/reduccmp.test: Test them.
* src/ltlvisit/simplify.hh (ltl_simplifier_options): New option
reduce_size_stricly.
* src/ltlvisit/simplify.cc (simplify_visitor): Implement these
rules.
* src/ltltest/reduc.cc: Check with reduce_size_strictly unset or
set, but only use the latter result to check sizes.
* src/ltltest/reduccmp.test: Test them.
* doc/tl/tl.tex: Document them.
The actual rules are a bit more complex:
a & X(G(a&b...)&c...) = Ga & X(G(b...)&c...)
a | X(Fa | c) = F(a) | c
with the second rule being applied only if all XF can
be removed. See the documentation for an example.
* src/ltlvisit/simplify.cc: Implement these new rules.
* doc/tl/tl.tex: Document them.
* src/ltltest/reduccmp.test: Add test cases.
* src/ltlvisit/simplify.cc: Implement them here, and augment them
to support M, and W operators.
* src/ltltest/reduccmp.test: Add some tests.
* doc/tl/tl.tex (Simplifications Based on Implications): Document
these rules.
* doc/tl/tl.bib (babiak.12.tacas): New entry.
* doc/tl/tl.tex: Replace all occurrences of ``rational
[expression]'' by SERE. Add a couple of more notes and
bibliographic references.
* doc/tl/tl.bib: More entries.
* src/ltlvisit/simplify.cc (simplify_visitor): Do it.
* src/ltltest/reduccmp.test: Add a test.
* doc/tl/tl.tex: Document it.
* src/ltlast/multop.cc: Fix the computation of is.accepting_eword
for Fusion. The Fusion operator never accepts [*0].
* doc/tl/Makefile.am: Rewrite using latexmk instead of texi2dvi.
Also define the SpotVersion when calling latexmk, not in tl.tex.
* doc/tl/tl.tex: Assume SpotVersion is defined outside the file.
Doxygen only knows how to call dot with -Tpng, while using
-Tpng:gd produces pictures that are 10 times smaller. Use a
simple wrapper around dot to simplify this.
* doc/dot.in: New file, that wrap the system's dot and replace
-Tpng by -Tpng:gd.
* doc/Makefile.am ($(srcdir)/stamp): Depend on dot.
* doc/Doxyfile.in: Update to 1.6.2.
(DOT_PATH): Set to @srcdir@ to use doc/dot instead of the
system's dot.
* configure.ac: Find the absolute path of dot, and generate
the doc/dot script.
* src/sanity/80columns.test, src/sanity/style.test: Process *.hxx files.
* src/tgbaalgos/ndfs_result.hh: Rename as ..
* src/tgbaalgos/ndfs_result.hxx: ... this, so it does not get
documented (and so Doxygen do not complain).
* src/tgbaalgos/magic.cc, src/tgbaalgos/se05.cc, src/tgbaalgos/tau03.cc,
src/tgbaalgos/tau03opt.cc: Adjust include.
* src/tgbaalgos/Makefile.am: Rename ndfs_result.hh as ndfs_result.hxx
and do not install it, this is a private header.
