2011-02-25  Enea Zaffanella <zaffanella@cs.unipr.it>

	* src/Row.defs.hh: Fixed a documentation problem in a \ref Doxygen
	command.

2011-02-23  Enea Zaffanella <zaffanella@cs.unipr.it>

	* src/Checked_Number.defs.hh, src/Checked_Number.inlines.hh: Avoid
	(again) using the same macro name for different purposes.  Doing it
	confuses both the reader and Doxygen.

2011-02-23  Enea Zaffanella <zaffanella@cs.unipr.it>

	* doc/devref-language-interface.tex, doc/devref.tex,
	doc/user-language-interface.tex, doc/user.tex: Get rid of LaTeX
	warnings related to package fancyhdr.

2011-02-23  Enea Zaffanella <zaffanella@cs.unipr.it>

	* doc/Makefile.am, doc/devref-language-interface.doxyconf.in,
	doc/user-language-interface.doxyconf.in,
	interfaces/C/C_interface.dox: Avoid duplicate PDF labels in the
	configured C interface manuals.

2011-02-23  Enea Zaffanella <zaffanella@cs.unipr.it>

	* doc/devref-language-interface.tex, doc/devref.tex,
	doc/user-language-interface.tex, doc/user.tex: Fixed a duplicate
	hypertarget error in the generated PDF documentation.

2011-02-23  Enea Zaffanella <zaffanella@cs.unipr.it>

	* src/Checked_Number.defs.hh, src/Checked_Number.inlines.hh: Avoid

	both the reader and Doxygen.

2011-02-23  Roberto Bagnara <bagnara@cs.unipr.it>

	* NEWS: Two items added.

2011-02-23  Roberto Bagnara <bagnara@cs.unipr.it>

	* m4/ac_check_gmp.m4: When cross-compiling, assume that GMP has been
	compiled with support for propagating exceptions.

2011-02-23  Roberto Bagnara <bagnara@cs.unipr.it>

	* src/fpu-ia32.cc: Work around a bug showing up under mingw-w64.

2011-02-23  Enea Zaffanella <zaffanella@cs.unipr.it>

	* Watchdog/doc/devref.doxyconf-latex.in,
	doc/devref-language-interface.doxyconf.in,
	doc/devref.doxyconf-latex.in: Set INLINE_SOURCES = NO when producing
	LaTeX documentation.  This change is a workaround to a pdftex + hyperref issue that may
	result in the following error    \pdfendlink ended up in different nesting level than
	   \pdfstartlink when using some versions of Doxygen (e.g., 1.7.3).  According to http://tug.org/errors.html the error is triggered when
	a hyperlink is split across page boundaries and it can be generated
	even by valid LaTeX code. Disabling source inlining is a way to
	greatly decrease its likelihood.

2011-02-22  Enea Zaffanella <zaffanella@cs.unipr.it>

	* src/meta_programming.hh: Fixed a couple of Doxygen related
	problems.

2011-02-22  Roberto Bagnara <bagnara@cs.unipr.it>

	* NEWS: Updated.

2011-02-22  Roberto Bagnara <bagnara@cs.unipr.it>

	* src/fpu-ia32.cc: No longer overwrite the SIGILL handler.

2011-02-21  Roberto Bagnara <bagnara@cs.unipr.it>

	*
	interfaces/Java/parma_polyhedra_library/Parma_Polyhedra_Library.jav
	a: Never use `\c';  use <CODE></CODE> instead (yes, uppercase).

2011-02-21  Roberto Bagnara <bagnara@cs.unipr.it>

	* NEWS, README.configure, configure.ac, m4/ac_check_fpu_control.m4: 
	The `--disable-fpmath' configure option now disables all floating
	point computations.

2011-02-20  Roberto Bagnara <bagnara@cs.unipr.it>

	* NEWS: Added missing news items.

2010-10-19  Enea Zaffanella <zaffanella@cs.unipr.it>

	* src/Octagonal_Shape.templates.hh,
	tests/Octagonal_Shape/affineimage1.cc: Improved precision of
	Octagonal_Shape::affine_image().  The method was rather imprecise on
	sign-symmetry affine transformations.  Also noted that strong
	reduction is preserved in that case.

2011-02-19  Roberto Bagnara <bagnara@cs.unipr.it>

	* ChangeLog, Watchdog/ChangeLog: Updated.

2011-02-19  Roberto Bagnara <bagnara@cs.unipr.it>

	doc/libppl.3, doc/libppl_c.3, doc/ppl-config.1: Updated for the
	release of PPL 0.11.1.

2011-02-17  Enea Zaffanella <zaffanella@cs.unipr.it>

	* src/Bit_Matrix.cc, src/Linear_System.cc,
	src/Linear_System.defs.hh, src/Linear_System.inlines.hh,
	src/swapping_sort.icc: Replaced the algorithm used for sorting
	Linear_System and Bit_Matrix.  The new algorithm, based on STL's std::sort and std::unique, is
	applied to a vector of rows' indices and implements indirect sort
	using function objects for the comparisons and swap operations.
	Apart from a (usually minor) decrease in the number of comparisons
	and swaps perfomed, the new algorithm should be better wrt the
	consumption of stack space, by getting rid of ad-hoc sort/unique
	functions, as well as the special-purpose iterator class
	Linear_System::With_Bit_Matrix_iterator.

2011-02-16  Roberto Bagnara <bagnara@cs.unipr.it>

	* tests/Polyhedron/Makefile.am: Disabled the `memory1' test (at
	least for the time being).

2011-02-16  Enea Zaffanella <zaffanella@cs.unipr.it>

	* tests/PIP_Problem/pipproblem1.cc: test06 no longer overflows when
	using 8-bit coefficients.

	* src/PIP_Problem.cc, src/PIP_Tree.cc, src/PIP_Tree.defs.hh,
	src/PIP_Tree.inlines.hh: The resolution process for PIP_Problem now
	better exploits the integrality of parameters to simplify the newly
	generated tautological constraints, the splitting constraints of
	decision nodes, and the expressions defining artificial parameters.

2011-02-14  Enea Zaffanella <zaffanella@cs.unipr.it>

	* src/PIP_Tree.defs.hh: Document parameter indent_level in
	PIP_Tree_Node::solve().

	parent: if the true child happened to be a decision node with both
	childs, the merging was causing the violation of a PIP_Decision_Node
	invariant.

2011-02-11  Enea Zaffanella <zaffanella@cs.unipr.it>

	src/PIP_Tree.cc, src/PIP_Tree.defs.hh, src/PIP_Tree.inlines.hh,
	tests/PIP_Problem/pipproblem1.cc: Changed interface for public
	method PIP_Solution_Node::parametric_values().  The new interface no longer requires the set of problem parameters
	as an input argument (which was error prone): rather, the set of
	parameters of the PIP_Problem is now automatically retrieved.  To this end, all PIP tree nodes are now provided by a pointer to the
	owning PIP_Problem object. Method PIP_Problem::OK() modified to
	check for well formedness of the solution tree and, in particular,
	check that all its nodes are marked as owned by the right
	PIP_Problem object.  Removed the no longer useful method
	PIP_Tree_Node::insert_artificials().  Corrected a typo in PIP_Problem::operator<<().  Simplified interface
	of (internal) method PIP_Tree_Node::print_tree().  Added a FIXME regarding a potential exception safety issue.

	* src/MIP_Problem.cc, src/MIP_Problem.defs.hh: Fixed a (potential)
	exception safety bug in class MIP_Problem.  Added an helper class
	(implementing RAII technique) to safely relax a MIP problem into an

	domain.  For these domains it checks if the expression has a constant value
	and if so, returns true and gives the value (with frequency 0).
	Otherwise it returns false.

	interfaces/Java/tests/ppl_interface_generator_java_test_java_code.m
	4, interfaces/Java/tests/ppl_java_tests_common: The generated Java
	tests now exploit the Test_Executor class functionality.  Added an
	helper function to set global success flag and report success or
	failure if in noisy mode.  NOTE: we are still (just) checking for
	the well formedness of the object (using method OK()), rather than
	checking if the computed result is actually the same of th expected
	one. However, due to genericity, it is quite difficult to precisely
	state expectations in these tests.

2009-05-18  Patricia Hill <p.m.hill@leeds.ac.uk>

	* : commit c8cbb00f29ac4c0d48daf14a9a9d3b93e559e207 Author: Patricia
	Hill <p.m.hill@leeds.ac.uk> Date:   Wed May 13 09:21:47 2009 +0100

2009-05-13  Roberto Bagnara <bagnara@cs.unipr.it>

	* m4/ac_check_gmp.m4: AC_CHECK_GMP fixed.

2009-05-12  Roberto Bagnara <bagnara@cs.unipr.it>

	* TODO: Added a commit to consider should we release PPL 0.10.3.

2009-05-12  Roberto Bagnara <bagnara@cs.unipr.it>

	* NEWS, README.configure, m4/ac_check_gmp.m4: New configuration
	option `--with-gmp-build=DIR'.  This allows to use a non-installed
	build of GMP in DIR.

2009-05-12  Enea Zaffanella <zaffanella@cs.unipr.it>

	* tests/Partially_Reduced_Product/directproduct6.cc: Known result
	adapted to increased Box constructor precision.

2009-05-12  Enea Zaffanella <zaffanella@cs.unipr.it>

	* TODO, tests/Box/frompolyhedron1.cc: Another TODO item dealt with.
	Adapted another few known results according to increased precision.

2009-05-12  Roberto Bagnara <bagnara@cs.unipr.it>

	* TODO: Added a section on commits to consider should we release PPL
	0.10.3.

2009-05-12  Enea Zaffanella <zaffanella@cs.unipr.it>

	* src/Box.defs.hh, src/Box.inlines.hh, src/Box.templates.hh,
	tests/Box/frompolyhedron2.cc, tests/Box/refinewithconstraint1.cc,
	tests/Powerset/frompolyhedron1.cc: Method Box::refine_with is now
	based on (single step) constraint propagation.  Method
	Box::propagate_constraints now also take as input a parameter for
	specifying the maximum number of iterations (default value 0).  The
	constructor of a Box from a Polyhedron in polynomial time sets this
	parameter to a constant.  The known result of several tests adapted
	to match the increased precision.

2009-05-12  Patricia Hill <p.m.hill@leeds.ac.uk>

	* doc/definitions.dox, src/Grid_public.cc: Improved documentation
	and small efficiency improvement to the code.

2009-05-12  Roberto Bagnara <bagnara@cs.unipr.it>

	* interfaces/Java/tests/Makefile.am: We cannot test the Java
	interface unless ENABLE_SHARED.

2009-05-12  Patricia Hill <p.m.hill@leeds.ac.uk>

	* src/Grid_public.cc: Another efficiency improvement to
	wrap_assign().

2009-05-12  Patricia Hill <p.m.hill@leeds.ac.uk>

	* src/Grid_public.cc: Some efficiency improvements. Comments
	improved.

2009-05-12  Abramo Bagnara <abramo.bagnara@gmail.com>

	* src/Boundary.defs.hh: Added smod_2exp and umod_2exp for boundary.

2009-05-12  Roberto Bagnara <bagnara@cs.unipr.it>

	* m4/lib-ld.m4, m4/lib-link.m4, m4/lib-prefix.m4: Updated from
	Gnulib.

2009-05-12  Patricia Hill <p.m.hill@leeds.ac.uk>

	* src/Grid.defs.hh, src/Grid_nonpublic.cc, src/Grid_public.cc: 
	Simplification and improvement of code for wrap_assign().  The bounds_no_check() and frequency_no_check() assume the generators
	are minimized and the grid is not empty.

2009-05-12  Patricia Hill <p.m.hill@leeds.ac.uk>

	* doc/definitions.dox, src/Grid_public.cc: Several improvements for
	the wrap_assign() operator for grids.

2009-05-11  Patricia Hill <p.m.hill@leeds.ac.uk>

	* src/Grid.defs.hh, src/Grid_public.cc, tests/Grid/wrap1.cc: 
	Improved code for wrap_assign() for grids for constant values.  If the value for a variable is already constant, and the constant is
	outside the range for the bounded integr type, then the outcome
	depends on the kind of overflow: - if `impossible', then the grid is set empty; - if `undefined', then the variable is set to take any integral
	value; - if `wraps', then the value is wrapped by the wrap_frequency   to a value in the range for the bounded integer type.  Comments improved.

2009-04-15  Roberto Bagnara <bagnara@cs.unipr.it>

	* m4/ac_check_gmp.m4: Accommodate version 4.3.0 of GMP.  Starting from GMP version 4.3.0 (released a few hours after PPL
	0.10.1), the gmp_version variable always contains three parts.  In
	previous versions the patchlevel was omitted if it was 0.  This
	change broke our GMP detection procedure.

	* devtools/generate_dox_biblio.sed, doc/definitions.dox:

	14, 2009.

2009-04-03  Enea Zaffanella <zaffanella@cs.unipr.it>

	* tests/Box/ascii_dump_load1.cc: Do not use the same object to play
	different roles in the same method call.  In calls to methods
	Box::difference_assign and Box::concatenate_assign we were binding
	the very same Box object both to the (modifiable) implicit argument
	*this and to the (const) explicit argument y.

2009-04-03  Enea Zaffanella <zaffanella@cs.unipr.it>

	* src/Box.templates.hh: Fixed a missing initialization bug in
	Box::concatenate_assign.  Also improved methods

	and later initialize them, we now directly add properly initialized
	intervals.

	* src/Pointset_Powerset.cc, src/Pointset_Powerset.defs.hh,

	Changes to deal with //FIXME(0.10.1): the following is a bug! in
	src/Pointset_Powerset.templates.hh As Grids are non-convex, the constructor for a powerset of nnc
	polyhedra from a powerset of grids has been implemented separately
	from the generic case. A test added to show that there was a bug
	which is now fixed.  The "//FIXME(0.10.1): ..." has been removed but a new FIXME added
	indicating this code will break if other non-convex or non-linear
	domains are added

2009-03-24  Enea Zaffanella <zaffanella@cs.unipr.it>

	* tests/Octagonal_Shape/affineimage1.cc: Test test17() shows a bug
	in method Octagonal_Shape::affine_image().  The bug is triggered
	  when the affine image is of the form var -> var + n and the

	src/c_streambuf_format.defs.hh: Separated wrap before from wrap
	after. Bug fixes.

2009-03-23  Roberto Bagnara <bagnara@cs.unipr.it>

	* src/OR_Matrix.inlines.hh, src/Octagonal_Shape.inlines.hh,
	src/Octagonal_Shape.templates.hh: Readability improvements.

2009-03-23  Roberto Bagnara <bagnara@cs.unipr.it>

	* src/OR_Matrix.inlines.hh: Fixed a bug (that is inconsequential for
	the current code base).  We were using `m % 2 == 1' instead of `m %
	2 != 0', with `m' a signed number that could be negative.

2009-03-23  Abramo Bagnara <abramo.bagnara@gmail.com>

	* src/c_stream.cc, src/c_stream.h: Added ppl_io_ostream_buffer_clear
	function.

2009-03-23  Abramo Bagnara <abramo.bagnara@gmail.com>

	* src/c_stream.cc, src/c_stream.h: Added write functions for native
	types.

	format filter.

2009-03-23  Enea Zaffanella <zaffanella@spartacus.cs.unipr.it>

	* doc/Makefile.am: Add dependencies between HTML manuals for
	parallel builds.  The distributed built HTML manuals logically
	depend on the built tag file, which is not distributed; hence a
	direct dependency cannot be added (it would break a `make distcheck'
	check). As a workaround, they now depend on the core HTML manual,
	which is built _and_ distributed.

2009-03-23  Roberto Bagnara <bagnara@cs.unipr.it>

	* src/OR_Matrix.inlines.hh: Obsolete FIXME removed.

2009-03-23  Roberto Bagnara <bagnara@cs.unipr.it>

	* src/Octagonal_Shape.templates.hh: Little formatting improvement.

2009-03-23  Enea Zaffanella <zaffanella@cs.unipr.it>

	* src/pretty_print.cc, src/pretty_print.hh: Use consistent parameter
	names in helper function wrap.

2009-03-22  Roberto Bagnara <bagnara@cs.unipr.it>

	* demos/ppl_lpsol/expected_mpz_a: Updated to reflect the new way
	`ppl_lpsol' is invoked.

2009-03-22  Roberto Bagnara <bagnara@cs.unipr.it>

	* Makefile.am, Watchdog/Makefile.am, Watchdog/pwl-config.sed,
	ppl-config.sed: Tightened the machinery used to generate the
	configuration headers.

2009-03-22  Enea Zaffanella <zaffanella@cs.unipr.it>

	* tests/Polyhedron/linearexpression1.cc: Added a test for
	operator-(var, expr) and operator-(expr, var).

2009-03-22  Roberto Bagnara <bagnara@cs.unipr.it>

	* src/Linear_Expression.cc, src/Linear_Expression.inlines.hh: 
	Improved functions and methods to build linear expressions.  Avoid
	complex inline functions and methods.

2009-03-22  Enea Zaffanella <zaffanella@cs.unipr.it>

	* src/Linear_Expression.cc, src/Linear_Expression.defs.hh,
	src/Linear_Expression.inlines.hh: Three FIXMEs related to
	Linear_Expression resolved.  The three operators are now friend of
	Linear_Expression: hence they can use the sizing constructors and
	limit the use of short-lived temporaries.

2009-03-22  Enea Zaffanella <zaffanella@cs.unipr.it>

	* src/Octagonal_Shape.templates.hh: Dealt with a FIXME related to
	variable names.

2009-03-22  Roberto Bagnara <bagnara@cs.unipr.it>

	* src/Linear_Expression.cc, src/Linear_Expression.defs.hh,
	src/Linear_Expression.inlines.hh, tests/Polyhedron/.gitignore,
	tests/Polyhedron/Makefile.am, tests/Polyhedron/linearexpression1.cc: 
	FIXME resolved.  Fixed a bug in Linear_Expression(Variable v,
	Variable w).  The bug would cause a wrong result to be computed when
	v == w.

2009-03-22  Enea Zaffanella <zaffanella@cs.unipr.it>

	* NEWS: Mention the bug fixed with Commit:

	preferred wrapping behavior.  For Prolog, new predicate is called
	ppl_CLASS_pretty_print_to_atom/5 and put the result in the last
	argument as an atom.  For Java, method takes a Writer as the first
	argument.  For Caml, function ppl_CLASS_pretty_print returns a caml
	string.  While at it, also added missing ascii_dump method to Caml and Java
	interfaces, as well as for the MIP_Problem Prolog interface.

2009-03-21  Roberto Bagnara <bagnara@cs.unipr.it>

2009-02-18  Roberto Bagnara <bagnara@cs.unipr.it>

	* fedora/ppl-0.10-configure.patch, fedora/ppl.spec: Install the
	documentation according to the Fedora packaging conventions.

2009-02-18  Roberto Bagnara <bagnara@cs.unipr.it>

	* fedora/ppl-0.10-bigendian.patch: Put under CVS control.

2009-02-18  Roberto Bagnara <bagnara@cs.unipr.it>

	* fedora/ppl.spec: Implemented a better workaround for the bug
	affecting PPL 0.10 on big-endian architectures.  There are no GNU Prolog packages available on s390 and s390: disable
	the GNU Prolog interface also on those platforms (besides ppc64).

2009-02-17  Roberto Bagnara <bagnara@cs.unipr.it>

	* src/Makefile.am: Avoid using GNU Make extensions.

2009-02-17  Roberto Bagnara <bagnara@cs.unipr.it>

	* src/MIP_Problem.cc: Two FIXMEs resolved.

2009-02-16  Roberto Bagnara <bagnara@cs.unipr.it>

	* tests/MIP_Problem/Makefile.am, tests/Polyhedron/Makefile.am,
	tests/ppl_test.hh: Include "ppl_header.hh" instead of "ppl.hh": this
	greatly facilitates debugging of test programs.

2009-02-15  Roberto Bagnara <bagnara@cs.unipr.it>

	* src/Makefile.am: In ppl_include_files.hh only list the include
	files that are not included by any other include file.

2009-02-15  Roberto Bagnara <bagnara@cs.unipr.it>

	* src/Ask_Tell.defs.hh, src/DB_Row.templates.hh,

	src/Powerset.templates.hh, src/checked_float.inlines.hh,
	src/iterator_to_const.defs.hh: Added missing inclusions.

2009-02-15  Roberto Bagnara <bagnara@cs.unipr.it>

	* src/fpu-ia32.inlines.hh, src/fpu.defs.hh: Include "compiler.hh" in
	fpu.defs.hh, not in fpu-ia32.inlines.hh.  As a general rule, do not
	include general-purpose include files in files that are only
	conditionally included.

2009-02-15  Roberto Bagnara <bagnara@cs.unipr.it>

	* configure.ac: Added missing control operator.

2009-02-15  Roberto Bagnara <bagnara@cs.unipr.it>

	* src/compiler.hh: Indentation fixed.

2009-02-15  Roberto Bagnara <bagnara@cs.unipr.it>

	* src/Partially_Reduced_Product.defs.hh: Include
	"Partially_Reduced_Product.templates.hh".

2009-02-15  Roberto Bagnara <bagnara@cs.unipr.it>

	* configure.ac, demos/ppl_lcdd/Makefile.am,
	demos/ppl_lpsol/Makefile.am: Check for the availability of `fgrep'
	or its Posix replacement `grep -F'.  Always use $(FGREP) or $(EGREP)
	in makefiles.

2009-02-15  Roberto Bagnara <bagnara@cs.unipr.it>

2009-02-04  Roberto Bagnara <bagnara@cs.unipr.it>

	* src/Float.defs.hh: Work around the bug affecting the library on
	big-endian architectures.

2009-02-03  Roberto Bagnara <bagnara@cs.unipr.it>

	* fedora/ppl.spec: Work around the bug affecting PPL 0.10 on
	big-endian architectures.

2009-02-02  Patricia M. Hill <hill@comp.leeds.ac.uk>

	* src/Grid_public.cc, tests/Grid/simplifyusingcontext1.cc: Improved
	the code for handling 0-dim empty polyhedra for
	Grid::simplify_using_context_assign().  Added a further test for the
	0-dim polyhedra.

2009-02-02  Enea Zaffanella <zaffanella@cs.unipr.it>

	* src/Polyhedron_public.cc: Corrected a bug in methods
	add(_recycled)_generator(s) and simplify_using_context_assign
	whereby an assertion could have failed under very specific
	conditions (zero-dim empty polyhedron with a computed inconsistent
	constraint system becoming a zero-dim universe polyhedron).

2009-02-02  Enea Zaffanella <zaffanella@cs.unipr.it>

	* tests/Polyhedron/addgenerator1.cc,
	tests/Polyhedron/addgenerators1.cc: New tests show an assertion
	failure when adding the vector space origin to an empty zero-dim
	space polyhedron, thereby turning it into a zero-dim universe
	polyhedron. The assertion only fails if the inconsistent constraint
	system of the empty polyhedron was previously generated.

2009-02-02  Patricia M. Hill <hill@comp.leeds.ac.uk>

	* tests/Polyhedron/simplifyusingcontext1.cc: Added three further
	tests to cover all 0-dim cases.  Reordered tests so that all the
	0-dim tests are consecutive (11-15).

2009-02-02  Patricia M. Hill <hill@comp.leeds.ac.uk>

	* tests/Polyhedron/simplifyusingcontext1.cc: Added test that has an
	assertion failure for 0-dim empty polyhedra.

2009-02-01  Patricia M. Hill <hill@comp.leeds.ac.uk>

	* tests/Grid/Makefile.am, tests/Grid/simplifyusingcontext1.cc: Tests
	for simplify_using_context_assign() for Grids.

2009-02-01  Patricia M. Hill <hill@comp.leeds.ac.uk>

	* src/Grid_public.cc: Added code for simplify_using_context_assign()
	for Grids.  Some other bugs in the comments fixed.

2009-01-30  Enea Zaffanella <zaffanella@cs.unipr.it>

	* interfaces/OCaml/Makefile.am: The parallel build problem should
	now be solved.

2009-01-28  Enea Zaffanella <zaffanella@cs.unipr.it>

	* tests/Box/Makefile.am, tests/Box/simplifyusingcontext1.cc: Added
	test file for method Box::simplify_using_cntext_assign().  Tests
	test01() and test02() marked as failing, since they depend on method
	Interval::empty_intersection_assign(), currently provided with a
	dummy implementation.

2009-01-28  Enea Zaffanella <zaffanella@cs.unipr.it>

	* src/Box.templates.hh: Drafted an implementation for
	Box::simplify_using_context_assign().

2009-01-28  Enea Zaffanella <zaffanella@cs.unipr.it>

	* src/Interval.templates.hh: Added dummy implementation for method
	empty_intersection_assign(); corrected partial implementation of
	method simplify_using_context_assign().

2009-01-28  Enea Zaffanella <zaffanella@cs.unipr.it>

	* src/Interval.defs.hh: Added specification for new Interval method   template <typename From>   typename Enable_If<Is_Interval<From>::value, void>::type   empty_intersection_assign(const From& y); to be used in the
	implementation of Box::simplify_using_context_assign.

2009-01-27  Roberto Bagnara <bagnara@cs.unipr.it>

	* configure.ac: Partially work around a bug of AX_PREFIX_CONFIG_H
	whereby WORDS_BIGENDIAN is not prefixed.  Version number bumped.

2009-01-27  Enea Zaffanella <zaffanella@cs.unipr.it>

	* src/Interval.templates.hh: Drafted a partial implementation for
	simplify_using_context_assign(); it assumes that the interval is
	toplogically closed and with no restrictions.

2009-01-27  Roberto Bagnara <bagnara@cs.unipr.it>

	* TODO: Added one urgent item.

2009-01-26  Enea Zaffanella <zaffanella@cs.unipr.it>

	* tests/Polyhedron/simplifyusingcontext1.cc: Test 01 overflows when
	using 8bit coefficients and assertions are turned on.

2009-01-26  Enea Zaffanella <zaffanella@cs.unipr.it>

	* src/C_Polyhedron.cc, src/NNC_Polyhedron.cc: Switch to new
	implementation of poly_hull_assign_if_exact(), based on the results
	stated in BagnaraHZ09.

2009-01-26  Roberto Bagnara <bagnara@cs.unipr.it>

	* configure.ac: Version number bumped.

2009-01-26  Roberto Bagnara <bagnara@cs.unipr.it>

	* demos/ppl_lpsol/ppl_lpsol.c: Support more versions of GLPK.

2009-01-26  Roberto Bagnara <bagnara@cs.unipr.it>

	* configure.ac: Fixed copy-and-paste mistake.

2009-01-26  Enea Zaffanella <zaffanella@cs.unipr.it>

	* tests/Polyhedron/polyhullifexact2.cc: Added tests corresponding to
	examples in BHZ09.

2009-01-26  Enea Zaffanella <zaffanella@cs.unipr.it>

	* tests/Polyhedron/polyhullifexact1.cc: Added a new test.

2009-01-26  Enea Zaffanella <zaffanella@cs.unipr.it>

	* src/Polyhedron_nonpublic.cc: Added implementation of the BHZ09
	exact upper bound test for NNC polyhedra; Factored out those parts
	that are common to the C polyhedron case.

2009-01-26  Enea Zaffanella <zaffanella@cs.unipr.it>

	* src/Polyhedron.defs.hh: Added declarations for two non-public
	methods (one for the C and another for the NNC case) implementing
	exact upper bound tests using BHZ09.

2009-01-24  Roberto Bagnara <bagnara@cs.unipr.it>

	* NEWS: Wording improved.

2009-01-24  Roberto Bagnara <bagnara@cs.unipr.it>

	* NEWS, README.configure, configure.ac, interfaces/C/Makefile.am,
	interfaces/Java/jni/Makefile.am,
	interfaces/Java/parma_polyhedra_library/Makefile.am,
	interfaces/Java/tests/Makefile.am, interfaces/OCaml/Makefile.am,
	interfaces/OCaml/tests/Makefile.am,
	interfaces/Prolog/Ciao/Makefile.am,
	interfaces/Prolog/GNU/Makefile.am, interfaces/Prolog/Makefile.am,
	interfaces/Prolog/SICStus/Makefile.am,
	interfaces/Prolog/SWI/Makefile.am,
	interfaces/Prolog/XSB/Makefile.am,
	interfaces/Prolog/YAP/Makefile.am,
	interfaces/Prolog/tests/Makefile.am, m4/m4.m4: The configuration
	script now explicitly checks that a recent enough version of GNU M4
	is available if at least one non-C++ interface is enabled (in
	previous versions this check was not performed and building the
	library could fail in a mysterious way).  That version is then used
	in all makefiles.  (Thanks to Tobias Grosser.) Improved configure.ac
	in various places.

2009-01-23  Roberto Bagnara <bagnara@cs.unipr.it>

	* NEWS, README.configure, configure.ac,
	interfaces/OCaml/Makefile.am, interfaces/OCaml/tests/Makefile.am: 
	New configuration option `--with-mlgmp=DIR' allows to specify the
	installation directory of the ML GMP package.

2009-01-23  Roberto Bagnara <bagnara@cs.unipr.it>

	* demos/ppl_lpsol/ppl_lpsol.c: Added missing const qualifier.

2009-01-21  Enea Zaffanella <zaffanella@cs.unipr.it>

	* interfaces/OCaml/Makefile.am: Corrected so as to behave correctly
	when using parallel builds: the build of <file>.cmx also generates
	<file>.o, which is a dependency for the generation of *.a.

2009-01-20  Roberto Bagnara <bagnara@cs.unipr.it>

	* demos/ppl_lpsol/ppl_lpsol.c: Fixed glpk_message_interceptor()
	(thanks to Kenneth MacKenzie).

2009-01-20  Enea Zaffanella <zaffanella@cs.unipr.it>

	* tests/Octagonal_Shape/upperboundifexact1.cc: Added test on (higher
	dimensional) hypercubes.

2009-01-20  Enea Zaffanella <zaffanella@cs.unipr.it>

	* src/Octagonal_Shape.templates.hh: The code fo rthe detection of
	non-redundant octagonal constraints factored out of the strong
	  reduction assign method into the new private method
	non_redundant_matrix_entries(), so that it can be reused in other
	contexts. In particular, now we also use it in the implementation of
	upper_bound_assign_if_exact().

2009-01-20  Enea Zaffanella <zaffanella@cs.unipr.it>

	* src/Octagonal_Shape.defs.hh: Declared a new (private) method that
	is meant to identify the non-redundant octagonal constraints without
	actually computing a strongly reduced matrix.

2009-01-20  Enea Zaffanella <zaffanella@cs.unipr.it>

	* tests/BD_Shape/upperboundifexact1.cc: Added a test on hypercubes.

2009-01-20  Enea Zaffanella <zaffanella@cs.unipr.it>

	* src/BD_Shape.templates.hh: Method
	BHZ09_upper_bound_assign_if_exact() improved by exploiting shortest
	path reduction so as to avoid checks on redundant constraints.

2009-01-19  Enea Zaffanella <zaffanella@cs.unipr.it>

	* tests/BD_Shape/upperboundifexact1.cc: Added another test.

2009-01-18  Roberto Bagnara <bagnara@cs.unipr.it>

	* TODO: Added one important item for next release.

2009-01-18  Enea Zaffanella <zaffanella@cs.unipr.it>

	* tests/Octagonal_Shape/upperboundifexact1.cc: Tests 1, 3, 4, 9 and
	10 now succeeds.

2009-01-18  Enea Zaffanella <zaffanella@cs.unipr.it>

	* src/Octagonal_Shape.defs.hh, src/Octagonal_Shape.inlines.hh,
	src/Octagonal_Shape.templates.hh: Drafted an implementation of
	Octagonal_Shape::upper_bound_assign_if_exact() based on the
	corresponding theorem in BagnaraHZ09.

2009-01-16  Patricia M. Hill <hill@comp.leeds.ac.uk>

	* tests/Octagonal_Shape/upperboundifexact1.cc: test10() revised.

2009-01-16  Patricia M. Hill <hill@comp.leeds.ac.uk>

	* tests/Octagonal_Shape/Makefile.am,
	tests/Octagonal_Shape/upperboundifexact1.cc: Added a test file for
	the upper_bound_if_exact() method - copied (with obvious edits) from the BD_Shape test directory.  As the current implementation just returns false, tests that would
	be expected to succeed have the "_F" tag.  An additional test10 is an example showing that more conditions are
	needed for octagonal shapes compared to the bd shapes.

2009-01-13  Enea Zaffanella <zaffanella@cs.unipr.it>

	* tests/BD_Shape/upperboundifexact1.cc: Test test09 no longer fails.

2009-01-13  Enea Zaffanella <zaffanella@cs.unipr.it>

	* src/BD_Shape.templates.hh: Corrected implementation of
	BHZ09_upper_bound_assign_if_exact().

2009-01-12  Patricia M. Hill <hill@comp.leeds.ac.uk>

	* tests/BD_Shape/upperboundifexact1.cc: Added a test showing a bug
	in the new algorithm.

2009-01-08  Enea Zaffanella <zaffanella@cs.unipr.it>

	* src/BD_Shape.defs.hh, src/BD_Shape.inlines.hh,
	src/BD_Shape.templates.hh: Drafted an implementation for
	BHZ09_upper_bound_assign_if_exact(); the public method
	upper_bound_assign_if_exact() is now based on this new (private)
	method.

2009-01-05  Patricia M. Hill <hill@comp.leeds.ac.uk>

	* src/Partially_Reduced_Product.defs.hh,
	src/Partially_Reduced_Product.inlines.hh,
	src/Partially_Reduced_Product.templates.hh,
	src/Partially_Reduced_Product.types.hh,
	tests/Partially_Reduced_Product/Makefile.am,
	tests/Partially_Reduced_Product/directproduct6.cc,
	tests/Partially_Reduced_Product/partiallyreducedproduct2.cc,
	tests/Partially_Reduced_Product/partiallyreducedproduct3.cc,
	tests/Partially_Reduced_Product/shrinkusingcongruences1.cc: Added a
	reduction method Shrink_Using_Congruences_Reduction<> and the
	product Shrink_Using_Congruences_Product<> that assumes this
	reduction.  Several "FIXME"s dealt with.
