-GNU GENERAL PUBLIC LICENSE
-
-                             Version 2, June 1991
-
-Copyright (C) 1989, 1991 Free Software Foundation, Inc. 675 Mass Ave,
-Cambridge, MA 02139, USA. Everyone is permitted to copy and distribute verbatim
-copies of this license document, but changing it is not allowed.
-
-                                   Preamble
-
-The licenses for most software are designed to take away your freedom to share
-and change it. By contrast, the GNU General Public License is intended to
-guarantee your freedom to share and change free software--to make sure the
-software is free for all its users. This General Public License applies to most
-of the Free Software Foundation's software and to any other program whose
-authors commit to using it. (Some other Free Software Foundation software is
-covered by the GNU Library General Public License instead.) You can apply it to
-your programs, too.
-
-When we speak of free software, we are referring to freedom, not price. Our
-General Public Licenses are designed to make sure that you have the freedom to
-distribute copies of free software (and charge for this service if you wish),
-that you receive source code or can get it if you want it, that you can change
-the software or use pieces of it in new free programs; and that you know you
-can do these things.
-
-To protect your rights, we need to make restrictions that forbid anyone to deny
-you these rights or to ask you to surrender the rights. These restrictions
-translate to certain responsibilities for you if you distribute copies of the
-software, or if you modify it.
-
-For example, if you distribute copies of such a program, whether gratis or for
-a fee, you must give the recipients all the rights that you have. You must make
-sure that they, too, receive or can get the source code. And you must show them
-these terms so they know their rights.
-
-We protect your rights with two steps: (1) copyright the software, and (2)
-offer you this license which gives you legal permission to copy, distribute
-and/or modify the software.
-
-Also, for each author's protection and ours, we want to make certain that
-everyone understands that there is no warranty for this free software. If the
-software is modified by someone else and passed on, we want its recipients to
-know that what they have is not the original, so that any problems introduced
-by others will not reflect on the original authors' reputations.
-
-Finally, any free program is threatened constantly by software patents. We wish
-to avoid the danger that redistributors of a free program will individually
-obtain patent licenses, in effect making the program proprietary. To prevent
-this, we have made it clear that any patent must be licensed for everyone's
-free use or not licensed at all.
-
-The precise terms and conditions for copying, distribution and modification
-follow.
-
-                         GNU GENERAL PUBLIC LICENSE
-      TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-0. This License applies to any program or other work which contains a notice
-placed by the copyright holder saying it may be distributed under the terms of
-this General Public License. The "Program", below, refers to any such program
-or work, and a "work based on the Program" means either the Program or any
-derivative work under copyright law: that is to say, a work containing the
-Program or a portion of it, either verbatim or with modifications and/or
-translated into another language. (Hereinafter, translation is included without
-limitation in the term "modification".) Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not covered by
-this License; they are outside its scope. The act of running the Program is not
-restricted, and the output from the Program is covered only if its contents
-constitute a work based on the Program (independent of having been made by
-running the Program). Whether that is true depends on what the Program does.
-
-1. You may copy and distribute verbatim copies of the Program's source code as
-you receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy an appropriate copyright notice and
-disclaimer of warranty; keep intact all the notices that refer to this License
-and to the absence of any warranty; and give any other recipients of the
-Program a copy of this License along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and you may
-at your option offer warranty protection in exchange for a fee.
-
-2. You may modify your copy or copies of the Program or any portion of it, thus
-forming a work based on the Program, and copy and distribute such modifications
-or work under the terms of Section 1 above, provided that you also meet all of
-these conditions:
-
-a) You must cause the modified files to carry prominent notices stating that
-you changed the files and the date of any change.
-
-b) You must cause any work that you distribute or publish, that in whole or in
-part contains or is derived from the Program or any part thereof, to be
-licensed as a whole at no charge to all third parties under the terms of this
-License.
-
-c) If the modified program normally reads commands interactively when run, you
-must cause it, when started running for such interactive use in the most
-ordinary way, to print or display an announcement including an appropriate
-copyright notice and a notice that there is no warranty (or else, saying that
-you provide a warranty) and that users may redistribute the program under these
-conditions, and telling the user how to view a copy of this License.
-(Exception: if the Program itself is interactive but does not normally print
-such an announcement, your work based on the Program is not required to print
-an announcement.)
-
-These requirements apply to the modified work as a whole. If identifiable
-sections of that work are not derived from the Program, and can be reasonably
-considered independent and separate works in themselves, then this License, and
-its terms, do not apply to those sections when you distribute them as separate
-works. But when you distribute the same sections as part of a whole which is a
-work based on the Program, the distribution of the whole must be on the terms
-of this License, whose permissions for other licensees extend to the entire
-whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest your
-rights to work written entirely by you; rather, the intent is to exercise the
-right to control the distribution of derivative or collective works based on
-the Program.
-
-In addition, mere aggregation of another work not based on the Program with the
-Program (or with a work based on the Program) on a volume of a storage or
-distribution medium does not bring the other work under the scope of this
-License.
-
-3. You may copy and distribute the Program (or a work based on it, under
-Section 2) in object code or executable form under the terms of Sections 1 and
-2 above provided that you also do one of the following:
-
-a) Accompany it with the complete corresponding machine-readable source code,
-which must be distributed under the terms of Sections 1 and 2 above on a medium
-customarily used for software interchange; or,
-
-b) Accompany it with a written offer, valid for at least three years, to give
-any third party, for a charge no more than your cost of physically performing
-source distribution, a complete machine-readable copy of the corresponding
-source code, to be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange; or,
-
-c) Accompany it with the information you received as to the offer to distribute
-corresponding source code. (This alternative is allowed only for noncommercial
-distribution and only if you received the program in object code or executable
-form with such an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for making
-modifications to it. For an executable work, complete source code means all the
-source code for all modules it contains, plus any associated interface
-definition files, plus the scripts used to control compilation and installation
-of the executable. However, as a special exception, the source code distributed
-need not include anything that is normally distributed (in either source or
-binary form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component itself
-accompanies the executable.
-
-If distribution of executable or object code is made by offering access to copy
-from a designated place, then offering equivalent access to copy the source
-code from the same place counts as distribution of the source code, even though
-third parties are not compelled to copy the source along with the object code.
-
-4. You may not copy, modify, sublicense, or distribute the Program except as
-expressly provided under this License. Any attempt otherwise to copy, modify,
-sublicense or distribute the Program is void, and will automatically terminate
-your rights under this License. However, parties who have received copies, or
-rights, from you under this License will not have their licenses terminated so
-long as such parties remain in full compliance.
-
-5. You are not required to accept this License, since you have not signed it.
-However, nothing else grants you permission to modify or distribute the Program
-or its derivative works. These actions are prohibited by law if you do not
-accept this License. Therefore, by modifying or distributing the Program (or
-any work based on the Program), you indicate your acceptance of this License to
-do so, and all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-6. Each time you redistribute the Program (or any work based on the Program),
-the recipient automatically receives a license from the original licensor to
-copy, distribute or modify the Program subject to these terms and conditions.
-You may not impose any further restrictions on the recipients' exercise of the
-rights granted herein. You are not responsible for enforcing compliance by
-third parties to this License.
-
-7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues), conditions
-are imposed on you (whether by court order, agreement or otherwise) that
-contradict the conditions of this License, they do not excuse you from the
-conditions of this License. If you cannot distribute so as to satisfy
-simultaneously your obligations under this License and any other pertinent
-obligations, then as a consequence you may not distribute the Program at all.
-For example, if a patent license would not permit royalty-free redistribution
-of the Program by all those who receive copies directly or indirectly through
-you, then the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under any
-particular circumstance, the balance of the section is intended to apply and
-the section as a whole is intended to apply in other circumstances.
-
-It is not the purpose of this section to induce you to infringe any patents or
-other property right claims or to contest validity of any such claims; this
-section has the sole purpose of protecting the integrity of the free software
-distribution system, which is implemented by public license practices. Many
-people have made generous contributions to the wide range of software
-distributed through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing to
-distribute software through any other system and a licensee cannot impose that
-choice.
-
-This section is intended to make thoroughly clear what is believed to be a
-consequence of the rest of this License.
-
-8. If the distribution and/or use of the Program is restricted in certain
-countries either by patents or by copyrighted interfaces, the original
-copyright holder who places the Program under this License may add an explicit
-geographical distribution limitation excluding those countries, so that
-distribution is permitted only in or among countries not thus excluded. In such
-case, this License incorporates the limitation as if written in the body of

+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+		  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
 this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
 
-9. The Free Software Foundation may publish revised and/or new versions of the
-General Public License from time to time. Such new versions will be similar in
-spirit to the present version, but may differ in detail to address new problems
-or concerns.
-
-Each version is given a distinguishing version number. If the Program specifies
-a version number of this License which applies to it and "any later version",
-you have the option of following the terms and conditions either of that
-version or of any later version published by the Free Software Foundation. If
-the Program does not specify a version number of this License, you may choose
-any version ever published by the Free Software Foundation.
-
-10. If you wish to incorporate parts of the Program into other free programs
-whose distribution conditions are different, write to the author to ask for
-permission. For software which is copyrighted by the Free Software Foundation,
-write to the Free Software Foundation; we sometimes make exceptions for this.
-Our decision will be guided by the two goals of preserving the free status of
-all derivatives of our free software and of promoting the sharing and reuse of
-software generally.
-
-                                 NO WARRANTY
-
-11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
-THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
-STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE
-PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
-INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND
-FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
-PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE,
-YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
-ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
-THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
-GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE
-OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR
-DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR
-A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH
-HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+			    NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.

+\`configure' configures cloog 0.18.0 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          @<:@@S|@ac_default_prefix@:>@
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          @<:@PREFIX@:>@
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if

+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help

+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          @<:@@S|@ac_default_prefix@:>@
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          @<:@PREFIX@:>@
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help

+\`configure' configures cloog 0.18.0 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:

+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          @<:@PREFIX@:>@
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help

+control overhead at a global level (across the entire program / all statements)
+by separating / splitting loops. option->fs/ls allow the equivalent of setting

+be allocated by the user with options->fs_ls_size set to the number of elements (always equal
+to the number of statements).  For any
+given loop, the first and last depths of all statements under it are looked at
+to determine if the loop should be separated (max across all fs' and ls' is
+taken). A user has to set fs meaningfully, i.e., for eg., if two statements i &
+j have a fused loop and fs[i], fs[j] specify separation for that level for stmt
+i but not for stmt j, the input is ambiguous and we will in this case not
+separate (since a max is taken). options->fs/ls override f/l; if fs/ls are not
+set or are set inconsistently (max across ls[i] < max across fs[i]), f/l take

-@noindent The @code{cloog_program_generate} function generates
-the data structure of the source code that scans the input
-polyhedra pointed by @code{program}
-according to the options pointed by @code{options}.

-@code{program}, thus the original structure is no longer available
-after a call to this function. It returns a pointer to a
-@code{CloogProgram} structure containing the
-solution in CLooG structures.

-The input @code{CloogProgram} structure must have only one loop level
-(no inner loops): there is one loop per statement block. For a given block,
-the corresponding loop carries the iteration domain, the statement block,
-and a loop stride initialized to 1. For instance, the input @code{CloogProgram} structure

-@noindent The function @code{cloog_program_pprint} is a pretty printer for
-@code{CloogProgram} structures when it is a solution provided by
-the @code{cloog_program_generate} function. It prints the code or pseudo-code in the
-file pointed by @code{file} (possibly @code{stdout}) with regards to the
-options pointed by @code{options}.
+@noindent A @code{CloogInput} structure represents the input to CLooG.
+It is essentially a @code{CloogUnionDomain} along with a context
+@code{CloogDomain}.  A @code{CloogInput} can be created from
+a @code{CloogDomain} and a @code{CloogUnionDomains} using
+@code{cloog_input_alloc}, or it can be read from a CLooG input
+file using @code{cloog_input_read}.  The latter also modifies
+the @code{language} field of the @code{CloogOptions} structure.
+The constructed @code{CloogInput} can be used as input
+to a @code{cloog_clast_create_from_input} call.
+
+A @code{CloogInput} data structure and a @code{CloogOptions} contain
+the same information as a .cloog file. This function dumps the .cloog
+description of the given data structures into a file.

+@end example
+@noindent
+The @code{clast_stmt} returned by @code{cloog_clast_create}
+is a @code{clast_root}.
+It contains a placeholder for all the variable names that appear
+in the AST and a (list of) nested statement(s).
+
+@noindent
+A @code{clast_assignment} assigns the value given by
+the @code{clast_expr} @code{RHS} to a variable named @code{LHS}.
+
+@noindent
+A @code{clast_block} groups a list of statements into one statement.
+These statements are only generated if the @code{block} option is set,
+@pxref{Statement Block} and @ref{CloogOptions}.
+
+@noindent
+A @code{clast_user_stmt} represents a call to a statement specified
+by the user, @pxref{CloogStatement}.
+@code{substitutions} is a list of @code{clast_assignment} statements
+assigning an expression in terms of the scattering dimensions to
+each of the original iterators in the original order.
+The @code{LHS}s of these assignments are left blank (@code{NULL}).
+The @code{domain} is set to @code{NULL} if the @code{save_domains} option
+is not set.  Otherwise, it is set to the set
+of values for the scattering dimensions
+for which this instance of the user statement is executed.
+Note that unless the @code{noscalars} option has been set, the
+constant scattering dimensions may have been removed from this set.
+
+@noindent
+A @code{clast_for} represents a for loop, iterating @code{body} for each
+value of @code{iterator} between @code{LB} and @code{UB} in steps
+of size @code{stride}.
+The @code{domain} is set to @code{NULL} if the @code{save_domains} option is not
+set.  Otherwise, it is set to the set of values for the scattering dimensions
+for which a user statement is executed inside this @code{clast_for}.  Note that
+unless the @code{noscalars} option has been set, the constant scattering
+dimensions may have been removed from this set.
+
+@noindent
+A @code{clast_guard} represents the guarded execution of the @code{then}
+(list of) statement(s) by a conjunction of @code{n} (in)equalities.
+Each (in)equality is represented by a @code{clast_equation}.
+@example
+struct clast_equation @{
+    struct clast_expr *	LHS;
+    struct clast_expr *	RHS;
+    int			sign;
+@};
+@end example
+@noindent
+The condition expressed by a @code{clast_equation} is
+@code{LHS <= RHS}, @code{LHS == RHS} or @code{LHS >= RHS}
+depending on whether @code{sign} is less than zero, equal
+to zero, or greater than zero.
+
+The dynamic type of a @code{clast_stmt} can be determined
+using the macro @code{CLAST_STMT_IS_A(stmt,type)},
+where @code{stmt} is a pointer to a @code{clast_stmt}
+and @code{type} is one of @code{stmt_root}, @code{stmt_ass},
+@code{stmt_user}, @code{stmt_block}, @code{stmt_for} or
+@code{stmt_guard}.
+Users are allowed to define their own statement types by
+assigning the @code{op} field of the statements a pointer
+to a @code{clast_stmt_op} structure.
+@example
+struct clast_stmt_op @{
+    void (*free)(struct clast_stmt *);
+@};
+@end example
+@noindent
+The @code{free} field of this structure should point
+to a function that frees the user defined statement.
+
+@noindent
+A @code{clast_expr} can be an identifier, a term,
+a binary expression or a reduction.
+@example
+enum clast_expr_type @{
+    clast_expr_name,
+    clast_expr_term,
+    clast_expr_bin,
+    clast_expr_red
+@};
+struct clast_expr @{
+    enum clast_expr_type type;
+@};
+void free_clast_expr(struct clast_expr *e);
+@end example
+
+@noindent
+Identifiers are of subtype @code{clast_name}.
+@example
+struct clast_name @{
+    struct clast_expr	expr;
+    const char *	name;
+@};
+struct clast_name *new_clast_name(const char *name);
+void free_clast_name(struct clast_name *t);
+@end example
+@noindent
+The character string pointed to by @code{name} is
+assumed to be part of the @code{CloogNames} structure
+in the root of the clast as is therefore not copied.
+
+@noindent
+Terms are of type @code{clast_term}.
+@example
+struct clast_term @{
+    struct clast_expr   expr;
+    cloog_int_t         val;
+    struct clast_expr  *var;
+@};
+struct clast_term *new_clast_term(cloog_int_t c, struct clast_expr *v);
+void free_clast_term(struct clast_term *t);
+@end example
+@noindent
+If @code{var} is set to @code{NULL}, then the term represents
+the integer value @code{val}.  Otherwise, it represents
+the term @code{val * var}.
+@code{new_clast_term} simply copies the @code{v} pointer
+without copying the underlying @code{clast_expr}.
+@code{free_clast_term}, on the other hand, recursively frees
+@code{var}.
+
+@noindent
+Binary expressions are of type @code{clast_bin_type} and
+represent either the floor of a division (fdiv),
+the ceil of a division (cdiv), an exact division or
+the remainder of an fdiv.
+@example
+enum clast_bin_type @{ clast_bin_fdiv, clast_bin_cdiv, 
+                      clast_bin_div, clast_bin_mod @};
+struct clast_binary @{
+    struct clast_expr   expr;
+    enum clast_bin_type type;
+    struct clast_expr*  LHS;
+    cloog_int_t         RHS;
+@};
+struct clast_binary *new_clast_binary(enum clast_bin_type t, 
+                          struct clast_expr *lhs, cloog_int_t rhs);
+void free_clast_binary(struct clast_binary *b);
+@end example
+
+@noindent
+Reductions are of type @code{clast_reduction} and
+can represent either the sum, the minimum or the maximum
+of its elements.
+@example
+enum clast_red_type @{ clast_red_sum, clast_red_min, clast_red_max @};
+struct clast_reduction @{
+    struct clast_expr   expr;
+    enum clast_red_type type;
+    int                 n;
+    struct clast_expr*  elts[1];
+@};
+struct clast_reduction *new_clast_reduction(enum clast_red_type t,
+                                            int n);
+void free_clast_reduction(struct clast_reduction *r);

+@node Retrieving version information
+@section Retrieving version information
+CLooG provides static and dynamic version checks to assist on
+including a compatible version of the library.
+A static version check at compile time can be achieved by
+querying the version constants defined in @code{version.h}:
+
+@itemize @bullet
+@item @code{CLOOG_VERSION_MAJOR}
+@item @code{CLOOG_VERSION_MINOR}
+@item @code{CLOOG_VERSION_REVISION}
+@end itemize
 
+This way it is possible to ensure the included headers are of the
+correct version. It is still possible that the installed CLooG
+library version differs from the installed headers.
+In order to avoid this, a dynamic version check is provided with
+the functions:
 
-@node cloog_program_scatter
-@subsection cloog_program_scatter
 @example
 @group
-void cloog_program_scatter

-) ;
+int cloog_version_major(void);
+int cloog_version_minor(void);
+int cloog_version_revision(void);
 @end group
 @end example
 
-@noindent The function @code{cloog_program_scatter} applies scattering
-functions to the @code{CloogProgram} structure pointed by @code{program}.
-Original domains of @code{program} are freed. Scattering functions
-are inside the @code{CloogDomainList} structure pointed by @code{scattering}.
-There must be as many scattering functions in the @code{CloogDomainList}
-structure as loops (i.e. iteration domains) in the @code{CloogProgram}
-structure. The first scattering function of the list will be applied to the
-iteration domain of the first loop in the program, and so on.
-@code{names} gives the scattering dimension names as an array of strings. If
-@code{names} is @code{NULL}, names are automatically generated: the name of
-the @math{n^{th}} scattering dimension will be @code{cn}.
-

-@node cloog_program_read
-@subsection cloog_program_read
-@example
-CloogProgram * cloog_program_read(FILE *) ;
-@end example
-@noindent The @code{cloog_program_read} function
-reads the program data from a CLooG input file
-(@pxref{Writing The Input File}). It takes
-as input a pointer to the file it has to read (possibly @code{stdin}), and
-return a pointer to the read @code{CloogProgram} structure.

-@subsection From Matrices to Domains and Conversely
-@example
-CloogMatrix * cloog_domain_domain2matrix(CloogDomain *) ;
-CloogDomain * cloog_domain_matrix2domain(CloogMatrix *) ;
-@end example
-@noindent Two functions are provided to translate a @code{CloogDomain}
-data structure to a @code{CloogMatrix} data structure and conversely.
-Each function takes as input a pointer to the data structure to translate
-and returns as output a pointer to the translated data structure. The
-input data structure if neither modified nor freed. They
-may be quite useful for e.g. pretty printing since it is more convenient
-in constraint (matrix) representation.
-
-
-@node Allocation and Initialization Functions
-@subsection Allocation and Initialization Functions
-@example
-CloogStructure * cloog_structure_malloc() ;
-@end example
-@noindent Each CLooG data structure has an allocation and initialization
-function as shown above, where @code{Structure} and @code{structure} have to
-be replaced by the name of the convenient structure (without @samp{Cloog} prefix) for
-instance @code{CloogLoop * cloog_loop_malloc() ;}. These functions return
-pointers to an allocated structure with fields set to convenient default
-values. @strong{Using those functions is mandatory} to support internal
-management fields and to avoid upward compatibility problems if
-new fields appear. An exception is @code{cloog_matrix_malloc} since the
-@code{CloogMatrix} comes directly from the PolyLib. It takes two parameters:
-the number of rows and columns of the matrix we want to allocate:
-@example
-CloogMatrix * cloog_matrix_malloc(unsigned nbrows, unsigned nbcolumns);
-@end example
-
-
-@node Memory Deallocation Functions
-@subsection Memory Deallocation Functions
-@example
-void cloog_structure_free(CloogStructure *) ;
-@end example
-@noindent Each CLooG data structure has a deallocation function as shown above,
- where @code{Structure} and @code{structure} have to
-be replaced by the name of the convenient structure (without @samp{Cloog} prefix) for
-instance @code{void cloog_loop_free(CloogLoop *) ;}. These functions
-free the allocated memory for the structure provided as input. They free
-memory recursively, i.e. they also free the allocated memory for the internal
-structures.
-@strong{Using those functions is mandatory} to avoid memory leaks on internal
-management fields and to avoid upward compatibility problems if
-new fields appear.
-
-
-@node Printing Functions
-@subsection Printing Functions
-@example
-void cloog_structure_print(FILE *, CloogStructure *) ;
-@end example
-@noindent Each CLooG data structure has a printing function as shown above,
- where @code{Structure} and @code{structure} have to
-be replaced by the name of the convenient structure (without @samp{Cloog} prefix) for
-instance @code{void cloog_loop_print(FILE *, CloogLoop *) ;}. These functions
-print the pointed structure (and its fields recursively) to the file provided
-as input (possibly @code{stdout}).
-
+By using both the static and the dynamic version check, it is possible
+to match CLooG's header version with the library's version.

+/* The CloogMatrix structure is equivalent to the PolyLib Matrix data structure
+ * (see Wil93). This structure is devoted to represent a set of constraints.
+ *
+ * The whole matrix is stored in memory row after row at the p_Init address. p
+ * is an array of pointers where p[i] points to the first element of the i^{th
+ * row. NbRows and NbColumns are respectively the number of rows and columns of
+ * the matrix. Each row corresponds to a constraint. The first element of each
+ * row is an equality/inequality tag. The constraint is an equality p(x) = 0 if
+ * the first element is 0, but it is an inequality p(x) \geq 0 if the first
+ * element is 1. The next elements are the unknown coefficients, followed by
+ * the parameter coefficients, then the constant term. For instance, the
+ * following three constraints:
+ *
+ *     -i + m  = 0
+ *     -j + n >= 0

+isl is a thread-safe C library for manipulating sets and relations
+of integer points bounded by affine constraints.  The descriptions of
+the sets and relations may involve both parameters and existentially
+quantified variables.  All computations are performed in exact integer
+arithmetic using GMP.
+
+isl is released under the MIT license, but depends on the LGPL GMP
+library.
+
+Minimal compilation instructions:
+
+	./configure
+	make
+	make install
+
+If you are taking the source from the git repository, then you first
+need to do
+
+	git clone git://repo.or.cz/isl.git
+	./autogen.sh
+
+For more information, see doc/user.pod or the generated documentation.
+
+New releases are announced on http://freecode.com/projects/isl

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a
+# configured tree to be moved without reconfiguration.

+\`configure' configures isl 0.11.1 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:

+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          @<:@PREFIX@:>@
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>

+  CXX         C++ compiler command
+  CXXFLAGS    C++ compiler flags
+  CPP         C preprocessor

+\`configure' configures isl 0.11.1 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

+                          @<:@PREFIX@:>@
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CXX         C++ compiler command
+  CXXFLAGS    C++ compiler flags
+  CPP         C preprocessor
+  CXXCPP      C++ preprocessor
+
+Use these variables to override the choices made by `configure' or to help

+\`configure' configures isl 0.11.1 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          @<:@@S|@ac_default_prefix@:>@
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          @<:@PREFIX@:>@
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CXX         C++ compiler command
+  CXXFLAGS    C++ compiler flags
+  CPP         C preprocessor
+  CXXCPP      C++ preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+

+  CXX         C++ compiler command
+  CXXFLAGS    C++ compiler flags
+  CPP         C preprocessor
+  CXXCPP      C++ preprocessor

+
+	Commits:
+
+	- make commits of logical units
+	- check for unnecessary whitespace with "git diff --check"
+	  before committing
+	- do not check in commented out code or unneeded files
+	- the first line of the commit message should be a short
+	  description and should skip the full stop
+	- the body should provide a meaningful commit message, which
+	  includes motivation for the change, and contrasts
+	  its implementation with previous behaviour
+	- if you want your work included in isl.git, add a
+	  "Signed-off-by: Your Name <you@example.com>" line to the
+	  commit message (or just use the option "-s" when
+	  committing) to confirm that you agree to the Developer's
+	  Certificate of Origin
+	- make sure that you have tests for the bug you are fixing
+	- make sure that the test suite passes after your commit
+
+	Patch:
+
+	- use "git format-patch -M" to create the patch
+	- do not PGP sign your patch
+	- do not attach your patch, but read in the mail
+	  body, unless you cannot teach your mailer to
+	  leave the formatting of the patch alone.
+	- be careful doing cut & paste into your mailer, not to
+	  corrupt whitespaces.
+	- provide additional information (which is unsuitable for
+	  the commit message) between the "---" and the diffstat
+	- if you change, add, or remove a command line option or
+	  make some other user interface change, the associated
+	  documentation should be updated as well.
+	- if your name is not writable in ASCII, make sure that
+	  you send off a message in the correct encoding.
+	- send the patch to the development mailing list
+	  (isl-development@googlegroups.com).  If you use
+	  git-send-email(1), please test it first by sending email
+	  to yourself.

+% (Placing it in the same directory as the LaTeX document should also work.)
+% This "chicago" style is based on newapa.bst (American Psych. Assoc.)
+% found at ymir.claremont.edu.
+%
+%   Citation format: (author-last-name year)
+%             (author-last-name and author-last-name year)
+%             (author-last-name, author-last-name, and author-last-name year)
+%             (author-last-name et al. year)
+%             (author-last-name)
+%             author-last-name (year)
+%             (author-last-name and author-last-name)
+%             (author-last-name et al.)
+%             (year) or (year,year)
+%             year or year,year
+%
+%   Reference list ordering: alphabetical by author or whatever passes
+%    for author in the absence of one.
+%
+% This BibTeX style has support for abbreviated author lists and for
+%    year-only citations.  This is done by having the citations
+%    actually look like
+%
+%    \citeauthoryear{full-author-info}{abbrev-author-info}{year}
+%
+% The LaTeX style has to have the following (or similar)
+%
+%     \let\@internalcite\cite
+%     \def\fullcite{\def\citeauthoryear##1##2##3{##1, ##3}\@internalcite}
+%     \def\fullciteA{\def\citeauthoryear##1##2##3{##1}\@internalcite}
+%     \def\shortcite{\def\citeauthoryear##1##2##3{##2, ##3}\@internalcite}
+%     \def\shortciteA{\def\citeauthoryear##1##2##3{##2}\@internalcite}
+%     \def\citeyear{\def\citeauthoryear##1##2##3{##3}\@internalcite}
+%
+% These TeX macro definitions are found in chicago.sty. Additional
+% commands to manipulate different components of a citation can be defined
+% so that, for example, you can list author's names without parentheses
+% if using a citation as a noun or object in a sentence.

+%
+% Features of chicago.bst:
+% =======================
+%
+% - full names used in citations, but abbreviated citations are available
+%   (see above)
+% - if an entry has a "month", then the month and year are also printed
+%   as part of that bibitem.
+% - all conjunctions use "and" instead of "\&"
+% - major modification from Chicago Manual of Style (13th ed.) is that
+%   only the first author in a reference appears last name first-
+%   additional authors appear as J. Q. Public.
+% - pages are listed as "pp. xx-xx" in all entry types except
+%   article entries.
+% - book, inbook, and manual use "location: publisher" (or organization)
+%   for address and publisher. All other types list publishers separately.
+% - "pp." are used to identify page numbers for all entry types except
+%   articles.
+% - organization is used as a citation label if neither author nor editor
+%   is present (for manuals).
+% - "et al." is used for long author and editor lists, or when "others"
+%   is used.
+%
+% Modifications and bug fixes from newapa.bst:
+% ===========================================
+%
+%   - added month, year to bib entries if month is present
+%   - fixed bug with In proceedings, added necessary comma after title
+%   - all conjunctions changed to "and" from "\&"
+%   - fixed bug with author labels in my.full.label: "et al." now is
+%        generated when "others" is an author name
+%   - major modification from Chicago Manual of Style (13th ed.) is that
+%     only the first author in a reference appears last name first-
+%     additional authors appear as J. Q. Public.
+%   - pages are listed as "pp. xx-xx" in all entry types except
+%     article entries. Unnecessary (IMHO) "()" around page numbers
+%     were removed, and page numbers now don't end with a period.
+%   - created chicago.sty for use with this bibstyle (required).
+%   - fixed bugs in FUNCTION {format.vol.num.pages} for missing volume,
+%     number, and /or pages. Renamed to format.jour.vol.
+%   - fixed bug in formatting booktitles: additional period an error if
+%     book has a volume.
+%   - fixed bug: editors usually given redundant period before next clause
+%     (format.editors.dot) removed.
+%   - added label support for organizations, if both author and editor
+%     are missing (from alpha.bst). If organization is too long, then
+%     the key field is used for abbreviated citations.
+%   - In proceedings or books of several volumes, no comma was written
+%     between the "Volume x" and the page numbers (this was intentional
+%     in newapa.bst). Fixed.
+%   - Some journals may not have volumes/numbers, only month/year (eg.
+%     IEEE Computer). Fixed bug in article style that assumed volume/number
+%     was always present.

+%
+% chicago.sty: Style file for use with bibtex style chicago.bst, for
+% bibliographies formatted according to the 13th Edition of the Chicago
+% Manual of Style.
+%
+% 'newapa.bst' was made from 'plain.bst', 'named.bst', and 'apalike.bst',
+% with lots of tweaking to make it look like APA style, along with tips
+% from Young Ryu and Brian Reiser's modifications of 'apalike.bst'.
+% newapa.sty formed the basis of this style, chicago.sty. Author-date
+% references in newapa.bst formed the basis for chicago.bst. Chicagoa.bst
+% supports annotations.
+%
+% Version 4 (August, 1992):
+% - fixed chicago.bst and chicagoa.bst to handle long author lists in
+%   sorting
+% - fixed chicago.bst and chicagoa.bst so that missing page numbers in
+%   ``article'' entries are handled correctly
+% - modified chicago.sty to format entries with 2nd and subsequent lines
+%   indented.
+%
+%   Citation format: (author-last-name year)
+%             (author-last-name and author-last-name year)
+%             (author-last-name et al. year)
+%             (author-last-name)
+%             author-last-name
+%             author-last-name (year)
+%             (author-last-name and author-last-name)
+%             (author-last-name et al.)
+%             (year) or (year,year)
+%             year or year,year
+%
+%   Reference list ordering: alphabetical by author or whatever passes
+%    for author in the absence of one.
+%
+% This BibTeX style has support for abbreviated author lists and for
+%    year-only citations.  This is done by having the citations
+%    actually look like
+%
+%    \citeauthoryear{full-author-info}{abbrev-author-info}{year}
+%
+% The LaTeX style has to have the following (or similar)
+%
+%     \let\@internalcite\cite
+%     \def\fullcite{\def\citeauthoryear##1##2##3{##1, ##3}\@internalcite}
+%     \def\fullciteA{\def\citeauthoryear##1##2##3{##1}\@internalcite}
+%     \def\shortcite{\def\citeauthoryear##1##2##3{##2, ##3}\@internalcite}
+%     \def\shortciteA{\def\citeauthoryear##1##2##3{##2}\@internalcite}
+%     \def\citeyear{\def\citeauthoryear##1##2##3{##3}\@internalcite}
+%
+% -------------------------------------------------------------------------
+% This file implements citations for the ``chicago'' bibliography style.
+%  Place it in a file called chicago.sty in the TeX search path.
+%(Placing it in the same directory as the LaTeX document should also work.)
+%
+%    This file is a modification of the ``newapa'' LaTeX style,
+%    originally adapted by Steven Spencer from the ``apalike'' LaTeX style.
+%    It was originally modified by Stephen N. Spencer, with further
+%    modifications by Young U. Ryu.
+%
+% The ``chicago'' BibTeX bibliography style creates citations with labels:
+%       \citeauthoryear{author-info}{abbrev. author-info}{year}
+%
+% These labels are processed by the following LaTeX commands:
+%
+%  \cite{key}
+%    which produces citations with full author list and year.
+%    eg. (Brown 1978; Jarke, Turner, Stohl, et al. 1985)
+%  \citeNP{key}
+%    which produces citations with full author list and year, but without
+%    enclosing parentheses:
+%    eg. Brown 1978; Jarke, Turner and Stohl 1985
+%  \citeA{key}
+%    which produces citations with only the full author list.
+%    eg. (Brown; Jarke, Turner and Stohl)
+%  \citeANP{key}
+%    which produces citations with only the full author list, without
+%    parentheses eg. Brown; Jarke, Turner and Stohl
+%  \citeN{key}
+%    which produces citations with the full author list and year, but
+%    can be used as nouns in a sentence; no parentheses appear around
+%    the author names, but only around the year.
+%      eg. Shneiderman (1978) states that......
+%    \citeN should only be used for a single citation.
+%  \shortcite{key}
+%    which produces citations with abbreviated author list and year.
+%  \shortciteNP{key}
+%    which produces citations with abbreviated author list and year.
+%  \shortciteA{key}
+%    which produces only the abbreviated author list.
+%  \shortciteANP{key}
+%    which produces only the abbreviated author list.
+%  \shortciteN{key}
+%    which produces the abbreviated author list and year, with only the
+%    year in parentheses. Use with only one citation.
+%  \citeyear{key}
+%    which produces the year information only, within parentheses.
+%  \citeyearNP{key}
+%    which produces the year information only.
+%
+% Abbreviated author lists use the ``et al.'' construct.
+%
+% `NP' means `no parentheses'.
+%
+% This LaTeX style file must be used with the ``chicago'' or ``chicagoa''
+% (annotated chicago style) BibTeX styles.

+\section{Simple Hull}\label{s:simple hull}
+
+It is sometimes useful to have a single
+basic set or basic relation that contains a given set or relation.
+For rational sets, the obvious choice would be to compute the
+(rational) convex hull.  For integer sets, the obvious choice
+would be the integer hull.
+However, {\tt isl} currently does not support an integer hull operation
+and even if it did, it would be fairly expensive to compute.
+The convex hull operation is supported, but it is also fairly
+expensive to compute given only an implicit representation.
+
+Usually, it is not required to compute the exact integer hull,
+and an overapproximation of this hull is sufficient.
+The ``simple hull'' of a set is such an overapproximation
+and it is defined as the (inclusion-wise) smallest basic set
+that is described by constraints that are translates of
+the constraints in the input set.
+This means that the simple hull is relatively cheap to compute
+and that the number of constraints in the simple hull is no
+larger than the number of constraints in the input.
+\begin{definition}[Simple Hull of a Set]
+The {\em simple hull} of a set
+$S = \bigcup_{1 \le i \le v} S_i$, with
+$$
+S : \Z^n \to 2^{\Z^d} : \vec s \mapsto
+S(\vec s) =
+\left\{\, \vec x \in \Z^d \mid \exists \vec z \in \Z^e :
+\bigvee_{1 \le i \le v}
+A_i \vec x + B_i \vec s + D_i \vec z + \vec c_i \geq \vec 0 \,\right\}
+$$
+is the set
+$$
+H : \Z^n \to 2^{\Z^d} : \vec s \mapsto
+S(\vec s) =
+\left\{\, \vec x \in \Z^d \mid \exists \vec z \in \Z^e :
+\bigwedge_{1 \le i \le v}
+A_i \vec x + B_i \vec s + D_i \vec z + \vec c_i + \vec K_i \geq \vec 0
+\,\right\}
+,
+$$
+with $\vec K_i$ the (component-wise) smallest non-negative integer vectors
+such that $S \subseteq H$.
+\end{definition}
+The $\vec K_i$ can be obtained by solving a number of
+LP problems, one for each element of each $\vec K_i$.
+If any LP problem is unbounded, then the corresponding constraint
+is dropped.
+
+\section{Parametric Integer Programming}
+
+\subsection{Introduction}\label{s:intro}
+
+Parametric integer programming \shortcite{Feautrier88parametric}
+is used to solve many problems within the context of the polyhedral model.
+Here, we are mainly interested in dependence analysis \shortcite{Fea91}
+and in computing a unique representation for existentially quantified
+variables.  The latter operation has been used for counting elements
+in sets involving such variables
+\shortcite{BouletRe98,Verdoolaege2005experiences} and lies at the core
+of the internal representation of {\tt isl}.
+
+Parametric integer programming was first implemented in \texttt{PipLib}.
+An alternative method for parametric integer programming
+was later implemented in {\tt barvinok} \cite{barvinok-0.22}.
+This method is not based on Feautrier's algorithm, but on rational
+generating functions \cite{Woods2003short} and was inspired by the
+``digging'' technique of \shortciteN{DeLoera2004Three} for solving
+non-parametric integer programming problems.
+
+In the following sections, we briefly recall the dual simplex
+method combined with Gomory cuts and describe some extensions
+and optimizations.  The main algorithm is applied to a matrix
+data structure known as a tableau.  In case of parametric problems,
+there are two tableaus, one for the main problem and one for
+the constraints on the parameters, known as the context tableau.
+The handling of the context tableau is described in \autoref{s:context}.
+
+\subsection{The Dual Simplex Method}
+
+Tableaus can be represented in several slightly different ways.
+In {\tt isl}, the dual simplex method uses the same representation
+as that used by its incremental LP solver based on the \emph{primal}
+simplex method.  The implementation of this LP solver is based
+on that of {\tt Simplify} \shortcite{Detlefs2005simplify}, which, in turn,
+was derived from the work of \shortciteN{Nelson1980phd}.
+In the original \shortcite{Nelson1980phd}, the tableau was implemented
+as a sparse matrix, but neither {\tt Simplify} nor the current
+implementation of {\tt isl} does so.
+
+Given some affine constraints on the variables,
+$A \vec x + \vec b \ge \vec 0$, the tableau represents the relationship
+between the variables $\vec x$ and non-negative variables
+$\vec y = A \vec x + \vec b$ corresponding to the constraints.
+The initial tableau contains $\begin{pmatrix}
+\vec b & A
+\end{pmatrix}$ and expresses the constraints $\vec y$ in the rows in terms
+of the variables $\vec x$ in the columns.  The main operation defined
+on a tableau exchanges a column and a row variable and is called a pivot.
+During this process, some coefficients may become rational.
+As in the \texttt{PipLib} implementation,
+{\tt isl} maintains a shared denominator per row.
+The sample value of a tableau is one where each column variable is assigned
+zero and each row variable is assigned the constant term of the row.
+This sample value represents a valid solution if each constraint variable
+is assigned a non-negative value, i.e., if the constant terms of
+rows corresponding to constraints are all non-negative.
+
+The dual simplex method starts from an initial sample value that
+may be invalid, but that is known to be (lexicographically) no
+greater than any solution, and gradually increments this sample value
+through pivoting until a valid solution is obtained.
+In particular, each pivot exchanges a row variable
+$r = -n + \sum_i a_i \, c_i$ with negative
+sample value $-n$ with a column variable $c_j$
+such that $a_j > 0$.  Since $c_j = (n + r - \sum_{i\ne j} a_i \, c_i)/a_j$,
+the new row variable will have a positive sample value $n$.
+If no such column can be found, then the problem is infeasible.
+By always choosing the column that leads to the (lexicographically)
+smallest increment in the variables $\vec x$,
+the first solution found is guaranteed to be the (lexicographically)
+minimal solution \cite{Feautrier88parametric}.
+In order to be able to determine the smallest increment, the tableau
+is (implicitly) extended with extra rows defining the original
+variables in terms of the column variables.
+If we assume that all variables are non-negative, then we know
+that the zero vector is no greater than the minimal solution and
+then the initial extended tableau looks as follows.
+$$
+\begin{tikzpicture}
+\matrix (m) [matrix of math nodes]
+{
+& {} & 1 & \vec c \\
+\vec x && |(top)| \vec 0 & I \\
+\vec r && \vec b & |(bottom)|A \\
+};
+\begin{pgfonlayer}{background}
+\node (core) [inner sep=0pt,fill=black!20,right delimiter=),left delimiter=(,fit=(top)(bottom)] {};
+\end{pgfonlayer}
+\end{tikzpicture}
+$$
+Each column in this extended tableau is lexicographically positive
+and will remain so because of the column choice explained above.
+It is then clear that the value of $\vec x$ will increase in each step.
+Note that there is no need to store the extra rows explicitly.
+If a given $x_i$ is a column variable, then the corresponding row
+is the unit vector $e_i$.  If, on the other hand, it is a row variable,
+then the row already appears somewhere else in the tableau.
+
+In case of parametric problems, the sign of the constant term
+may depend on the parameters.  Each time the constant term of a constraint row
+changes, we therefore need to check whether the new term can attain
+negative and/or positive values over the current set of possible
+parameter values, i.e., the context.
+If all these terms can only attain non-negative values, the current
+state of the tableau represents a solution.  If one of the terms
+can only attain non-positive values and is not identically zero,
+the corresponding row can be pivoted.
+Otherwise, we pick one of the terms that can attain both positive
+and negative values and split the context into a part where
+it only attains non-negative values and a part where it only attains
+negative values.
+
+\subsection{Gomory Cuts}
+
+The solution found by the dual simplex method may have
+non-integral coordinates.  If so, some rational solutions
+(including the current sample value), can be cut off by
+applying a (parametric) Gomory cut.
+Let $r = b(\vec p) + \sp {\vec a} {\vec c}$ be the row
+corresponding to the first non-integral coordinate of $\vec x$,
+with $b(\vec p)$ the constant term, an affine expression in the
+parameters $\vec p$, i.e., $b(\vec p) = \sp {\vec f} {\vec p} + g$.
+Note that only row variables can attain
+non-integral values as the sample value of the column variables is zero.
+Consider the expression
+$b(\vec p) - \ceil{b(\vec p)} + \sp {\fract{\vec a}} {\vec c}$,
+with $\ceil\cdot$ the ceiling function and $\fract\cdot$ the
+fractional part.  This expression is negative at the sample value
+since $\vec c = \vec 0$ and $r = b(\vec p)$ is fractional, i.e.,
+$\ceil{b(\vec p)} > b(\vec p)$.  On the other hand, for each integral
+value of $r$ and $\vec c \ge 0$, the expression is non-negative
+because $b(\vec p) - \ceil{b(\vec p)} > -1$.
+Imposing this expression to be non-negative therefore does not
+invalidate any integral solutions, while it does cut away the current
+fractional sample value.  To be able to formulate this constraint,
+a new variable $q = \floor{-b(\vec p)} = - \ceil{b(\vec p)}$ is added
+to the context.  This integral variable is uniquely defined by the constraints
+$0 \le -d \, b(\vec p) - d \, q \le d - 1$, with $d$ the common
+denominator of $\vec f$ and $g$.  In practice, the variable
+$q' = \floor{\sp {\fract{-f}} {\vec p} + \fract{-g}}$ is used instead
+and the coefficients of the new constraint are adjusted accordingly.
+The sign of the constant term of this new constraint need not be determined
+as it is non-positive by construction.
+When several of these extra context variables are added, it is important
+to avoid adding duplicates.
+Recent versions of {\tt PipLib} also check for such duplicates.
+
+\subsection{Negative Unknowns and Maximization}
+
+There are two places in the above algorithm where the unknowns $\vec x$
+are assumed to be non-negative: the initial tableau starts from
+sample value $\vec x = \vec 0$ and $\vec c$ is assumed to be non-negative
+during the construction of Gomory cuts.
+To deal with negative unknowns, \shortciteN[Appendix A.2]{Fea91}
+proposed to use a ``big parameter'', say $M$, that is taken to be
+an arbitrarily large positive number.  Instead of looking for the
+lexicographically minimal value of $\vec x$, we search instead
+for the lexicographically minimal value of $\vec x' = \vec M + \vec x$.
+The sample value $\vec x' = \vec 0$ of the initial tableau then
+corresponds to $\vec x = -\vec M$, which is clearly not greater than
+any potential solution.  The sign of the constant term of a row
+is determined lexicographically, with the coefficient of $M$ considered
+first.  That is, if the coefficient of $M$ is not zero, then its sign
+is the sign of the entire term.  Otherwise, the sign is determined
+by the remaining affine expression in the parameters.
+If the original problem has a bounded optimum, then the final sample
+value will be of the form $\vec M + \vec v$ and the optimal value
+of the original problem is then $\vec v$.
+Maximization problems can be handled in a similar way by computing
+the minimum of $\vec M - \vec x$.
+
+When the optimum is unbounded, the optimal value computed for
+the original problem will involve the big parameter.
+In the original implementation of {\tt PipLib}, the big parameter could
+even appear in some of the extra variables $\vec q$ created during
+the application of a Gomory cut.  The final result could then contain
+implicit conditions on the big parameter through conditions on such
+$\vec q$ variables.  This problem was resolved in later versions
+of {\tt PipLib} by taking $M$ to be divisible by any positive number.
+The big parameter can then never appear in any $\vec q$ because
+$\fract {\alpha M } = 0$.  It should be noted, though, that an unbounded
+problem usually (but not always)
+indicates an incorrect formulation of the problem.
+
+The original version of {\tt PipLib} required the user to ``manually''
+add a big parameter, perform the reformulation and interpret the result
+\shortcite{Feautrier02}.  Recent versions allow the user to simply
+specify that the unknowns may be negative or that the maximum should
+be computed and then these transformations are performed internally.
+Although there are some application, e.g.,
+that of \shortciteN{Feautrier92multi},
+where it is useful to have explicit control over the big parameter,
+negative unknowns and maximization are by far the most common applications
+of the big parameter and we believe that the user should not be bothered
+with such implementation issues.
+The current version of {\tt isl} therefore does not
+provide any interface for specifying big parameters.  Instead, the user
+can specify whether a maximum needs to be computed and no assumptions
+are made on the sign of the unknowns.  Instead, the sign of the unknowns
+is checked internally and a big parameter is automatically introduced when
+needed.  For compatibility with {\tt PipLib}, the {\tt isl\_pip} tool
+does explicitly add non-negativity constraints on the unknowns unless
+the \verb+Urs_unknowns+ option is specified.
+Currently, there is also no way in {\tt isl} of expressing a big
+parameter in the output.  Even though
+{\tt isl} makes the same divisibility assumption on the big parameter
+as recent versions of {\tt PipLib}, it will therefore eventually
+produce an error if the problem turns out to be unbounded.
+
+\subsection{Preprocessing}
+
+In this section, we describe some transformations that are
+or can be applied in advance to reduce the running time
+of the actual dual simplex method with Gomory cuts.
+
+\subsubsection{Feasibility Check and Detection of Equalities}
+
+Experience with the original {\tt PipLib} has shown that Gomory cuts
+do not perform very well on problems that are (non-obviously) empty,
+i.e., problems with rational solutions, but no integer solutions.
+In {\tt isl}, we therefore first perform a feasibility check on
+the original problem considered as a non-parametric problem
+over the combined space of unknowns and parameters.
+In fact, we do not simply check the feasibility, but we also
+check for implicit equalities among the integer points by computing
+the integer affine hull.  The algorithm used is the same as that
+described in \autoref{s:GBR} below.
+Computing the affine hull is fairly expensive, but it can
+bring huge benefits if any equalities can be found or if the problem
+turns out to be empty.
+
+\subsubsection{Constraint Simplification}
+
+If the coefficients of the unknown and parameters in a constraint
+have a common factor, then this factor should be removed, possibly
+rounding down the constant term.  For example, the constraint
+$2 x - 5 \ge 0$ should be simplified to $x - 3 \ge 0$.
+{\tt isl} performs such simplifications on all sets and relations.
+Recent versions of {\tt PipLib} also perform this simplification
+on the input.
+
+\subsubsection{Exploiting Equalities}\label{s:equalities}
+
+If there are any (explicit) equalities in the input description,
+{\tt PipLib} converts each into a pair of inequalities.
+It is also possible to write $r$ equalities as $r+1$ inequalities
+\shortcite{Feautrier02}, but it is even better to \emph{exploit} the
+equalities to reduce the dimensionality of the problem.
+Given an equality involving at least one unknown, we pivot
+the row corresponding to the equality with the column corresponding
+to the last unknown with non-zero coefficient.  The new column variable
+can then be removed completely because it is identically zero,
+thereby reducing the dimensionality of the problem by one.
+The last unknown is chosen to ensure that the columns of the initial
+tableau remain lexicographically positive.  In particular, if
+the equality is of the form $b + \sum_{i \le j} a_i \, x_i = 0$ with
+$a_j \ne 0$, then the (implicit) top rows of the initial tableau
+are changed as follows
+$$
+\begin{tikzpicture}
+\matrix [matrix of math nodes]
+{
+ & {} & |(top)| 0 & I_1 & |(j)| &  \\
+j && 0 & & 1 & \\
+  && 0 & & & |(bottom)|I_2 \\
+};
+\node[overlay,above=2mm of j,anchor=south]{j};
+\begin{pgfonlayer}{background}
+\node (m) [inner sep=0pt,fill=black!20,right delimiter=),left delimiter=(,fit=(top)(bottom)] {};
+\end{pgfonlayer}
+\begin{scope}[xshift=4cm]
+\matrix [matrix of math nodes]
+{
+ & {} & |(top)| 0 & I_1 &  \\
+j && |(left)| -b/a_j & -a_i/a_j & \\
+  && 0 & & |(bottom)|I_2 \\
+};
+\begin{pgfonlayer}{background}
+\node (m2) [inner sep=0pt,fill=black!20,right delimiter=),left delimiter=(,fit=(top)(bottom)(left)] {};
+\end{pgfonlayer}
+\end{scope}
+ \draw [shorten >=7mm,-to,thick,decorate,
+        decoration={snake,amplitude=.4mm,segment length=2mm,
+                    pre=moveto,pre length=5mm,post length=8mm}]
+   (m) -- (m2);
+\end{tikzpicture}
+$$
+Currently, {\tt isl} also eliminates equalities involving only parameters
+in a similar way, provided at least one of the coefficients is equal to one.
+The application of parameter compression (see below)
+would obviate the need for removing parametric equalities.
+
+\subsubsection{Offline Symmetry Detection}\label{s:offline}
+
+Some problems, notably those of \shortciteN{Bygde2010licentiate},
+have a collection of constraints, say
+$b_i(\vec p) + \sp {\vec a} {\vec x} \ge 0$,
+that only differ in their (parametric) constant terms.
+These constant terms will be non-negative on different parts
+of the context and this context may have to be split for each
+of the constraints.  In the worst case, the basic algorithm may
+have to consider all possible orderings of the constant terms.
+Instead, {\tt isl} introduces a new parameter, say $u$, and
+replaces the collection of constraints by the single
+constraint $u + \sp {\vec a} {\vec x} \ge 0$ along with
+context constraints $u \le b_i(\vec p)$.
+Any solution to the new system is also a solution
+to the original system since
+$\sp {\vec a} {\vec x} \ge -u \ge -b_i(\vec p)$.
+Conversely, $m = \min_i b_i(\vec p)$ satisfies the constraints
+on $u$ and therefore extends a solution to the new system.
+It can also be plugged into a new solution.
+See \autoref{s:post} for how this substitution is currently performed
+in {\tt isl}.
+The method described in this section can only detect symmetries
+that are explicitly available in the input.
+See \autoref{s:online} for the detection
+and exploitation of symmetries that appear during the course of
+the dual simplex method.
+
+\subsubsection{Parameter Compression}\label{s:compression}
+
+It may in some cases be apparent from the equalities in the problem
+description that there can only be a solution for a sublattice
+of the parameters.  In such cases ``parameter compression''
+\shortcite{Meister2004PhD,Meister2008} can be used to replace
+the parameters by alternative ``dense'' parameters.
+For example, if there is a constraint $2x = n$, then the system
+will only have solutions for even values of $n$ and $n$ can be replaced
+by $2n'$.  Similarly, the parameters $n$ and $m$ in a system with
+the constraint $2n = 3m$ can be replaced by a single parameter $n'$
+with $n=3n'$ and $m=2n'$.
+It is also possible to perform a similar compression on the unknowns,
+but it would be more complicated as the compression would have to
+preserve the lexicographical order.  Moreover, due to our handling
+of equalities described above there should be
+no need for such variable compression.
+Although parameter compression has been implemented in {\tt isl},
+it is currently not yet used during parametric integer programming.
+
+\subsection{Postprocessing}\label{s:post}
+
+The output of {\tt PipLib} is a quast (quasi-affine selection tree).
+Each internal node in this tree corresponds to a split of the context
+based on a parametric constant term in the main tableau with indeterminate
+sign.  Each of these nodes may introduce extra variables in the context
+corresponding to integer divisions.  Each leaf of the tree prescribes
+the solution in that part of the context that satisfies all the conditions
+on the path leading to the leaf.
+Such a quast is a very economical way of representing the solution, but
+it would not be suitable as the (only) internal representation of
+sets and relations in {\tt isl}.  Instead, {\tt isl} represents
+the constraints of a set or relation in disjunctive normal form.
+The result of a parametric integer programming problem is then also
+converted to this internal representation.  Unfortunately, the conversion
+to disjunctive normal form can lead to an explosion of the size
+of the representation.
+In some cases, this overhead would have to be paid anyway in subsequent
+operations, but in other cases, especially for outside users that just
+want to solve parametric integer programming problems, we would like
+to avoid this overhead in future.  That is, we are planning on introducing
+quasts or a related representation as one of several possible internal
+representations and on allowing the output of {\tt isl\_pip} to optionally
+be printed as a quast.
+
+Currently, {\tt isl} also does not have an internal representation
+for expressions such as $\min_i b_i(\vec p)$ from the offline
+symmetry detection of \autoref{s:offline}.
+Assume that one of these expressions has $n$ bounds $b_i(\vec p)$.
+If the expression
+does not appear in the affine expression describing the solution,
+but only in the constraints, and if moreover, the expression
+only appears with a positive coefficient, i.e.,
+$\min_i b_i(\vec p) \ge f_j(\vec p)$, then each of these constraints
+can simply be reduplicated $n$ times, once for each of the bounds.
+Otherwise, a conversion to disjunctive normal form
+leads to $n$ cases, each described as $u = b_i(\vec p)$ with constraints
+$b_i(\vec p) \le b_j(\vec p)$ for $j > i$
+and
+$b_i(\vec p)  < b_j(\vec p)$ for $j < i$.
+Note that even though this conversion leads to a size increase
+by a factor of $n$, not detecting the symmetry could lead to
+an increase by a factor of $n!$ if all possible orderings end up being
+considered.
+
+\subsection{Context Tableau}\label{s:context}
+
+The main operation that a context tableau needs to provide is a test
+on the sign of an affine expression over the elements of the context.
+This sign can be determined by solving two integer linear feasibility
+problems, one with a constraint added to the context that enforces
+the expression to be non-negative and one where the expression is
+negative.  As already mentioned by \shortciteN{Feautrier88parametric},
+any integer linear feasibility solver could be used, but the {\tt PipLib}
+implementation uses a recursive call to the dual simplex with Gomory
+cuts algorithm to determine the feasibility of a context.
+In {\tt isl}, two ways of handling the context have been implemented,
+one that performs the recursive call and one, used by default, that
+uses generalized basis reduction.
+We start with some optimizations that are shared between the two
+implementations and then discuss additional details of each of them.
+
+\subsubsection{Maintaining Witnesses}\label{s:witness}
+
+A common feature of both integer linear feasibility solvers is that
+they will not only say whether a set is empty or not, but if the set
+is non-empty, they will also provide a \emph{witness} for this result,
+i.e., a point that belongs to the set.  By maintaining a list of such
+witnesses, we can avoid many feasibility tests during the determination
+of the signs of affine expressions.  In particular, if the expression
+evaluates to a positive number on some of these points and to a negative
+number on some others, then no feasibility test needs to be performed.
+If all the evaluations are non-negative, we only need to check for the
+possibility of a negative value and similarly in case of all
+non-positive evaluations.  Finally, in the rare case that all points
+evaluate to zero or at the start, when no points have been collected yet,
+one or two feasibility tests need to be performed depending on the result
+of the first test.
+
+When a new constraint is added to the context, the points that
+violate the constraint are temporarily removed.  They are reconsidered
+when we backtrack over the addition of the constraint, as they will
+satisfy the negation of the constraint.  It is only when we backtrack
+over the addition of the points that they are finally removed completely.
+When an extra integer division is added to the context,
+the new coordinates of the
+witnesses can easily be computed by evaluating the integer division.
+The idea of keeping track of witnesses was first used in {\tt barvinok}.
+
+\subsubsection{Choice of Constant Term on which to Split}
+
+Recall that if there are no rows with a non-positive constant term,
+but there are rows with an indeterminate sign, then the context
+needs to be split along the constant term of one of these rows.
+If there is more than one such row, then we need to choose which row
+to split on first.  {\tt PipLib} uses a heuristic based on the (absolute)
+sizes of the coefficients.  In particular, it takes the largest coefficient
+of each row and then selects the row where this largest coefficient is smaller
+than those of the other rows.
+
+In {\tt isl}, we take that row for which non-negativity of its constant
+term implies non-negativity of as many of the constant terms of the other
+rows as possible.  The intuition behind this heuristic is that on the
+positive side, we will have fewer negative and indeterminate signs,
+while on the negative side, we need to perform a pivot, which may
+affect any number of rows meaning that the effect on the signs
+is difficult to predict.  This heuristic is of course much more
+expensive to evaluate than the heuristic used by {\tt PipLib}.
+More extensive tests are needed to evaluate whether the heuristic is worthwhile.
+
+\subsubsection{Dual Simplex + Gomory Cuts}
+
+When a new constraint is added to the context, the first steps
+of the dual simplex method applied to this new context will be the same
+or at least very similar to those taken on the original context, i.e.,
+before the constraint was added.  In {\tt isl}, we therefore apply
+the dual simplex method incrementally on the context and backtrack
+to a previous state when a constraint is removed again.
+An initial implementation that was never made public would also
+keep the Gomory cuts, but the current implementation backtracks
+to before the point where Gomory cuts are added before adding
+an extra constraint to the context.
+Keeping the Gomory cuts has the advantage that the sample value
+is always an integer point and that this point may also satisfy
+the new constraint.  However, due to the technique of maintaining
+witnesses explained above,
+we would not perform a feasibility test in such cases and then
+the previously added cuts may be redundant, possibly resulting
+in an accumulation of a large number of cuts.
+
+If the parameters may be negative, then the same big parameter trick
+used in the main tableau is applied to the context.  This big parameter
+is of course unrelated to the big parameter from the main tableau.
+Note that it is not a requirement for this parameter to be ``big'',
+but it does allow for some code reuse in {\tt isl}.
+In {\tt PipLib}, the extra parameter is not ``big'', but this may be because
+the big parameter of the main tableau also appears
+in the context tableau.
+
+Finally, it was reported by \shortciteN{Galea2009personal}, who
+worked on a parametric integer programming implementation
+in {\tt PPL} \shortcite{PPL},
+that it is beneficial to add cuts for \emph{all} rational coordinates
+in the context tableau.  Based on this report,
+the initial {\tt isl} implementation was adapted accordingly.
+
+\subsubsection{Generalized Basis Reduction}\label{s:GBR}
+
+The default algorithm used in {\tt isl} for feasibility checking
+is generalized basis reduction \shortcite{Cook1991implementation}.
+This algorithm is also used in the {\tt barvinok} implementation.
+The algorithm is fairly robust, but it has some overhead.
+We therefore try to avoid calling the algorithm in easy cases.
+In particular, we incrementally keep track of points for which
+the entire unit hypercube positioned at that point lies in the context.
+This set is described by translates of the constraints of the context
+and if (rationally) non-empty, any rational point
+in the set can be rounded up to yield an integer point in the context.
+
+A restriction of the algorithm is that it only works on bounded sets.
+The affine hull of the recession cone therefore needs to be projected
+out first.  As soon as the algorithm is invoked, we then also
+incrementally keep track of this recession cone.  The reduced basis
+found by one call of the algorithm is also reused as initial basis
+for the next call.
+
+Some problems lead to the
+introduction of many integer divisions.  Within a given context,
+some of these integer divisions may be equal to each other, even
+if the expressions are not identical, or they may be equal to some
+affine combination of other variables.
+To detect such cases, we compute the affine hull of the context
+each time a new integer division is added.  The algorithm used
+for computing this affine hull is that of \shortciteN{Karr1976affine},
+while the points used in this algorithm are obtained by performing
+integer feasibility checks on that part of the context outside
+the current approximation of the affine hull.
+The list of witnesses is used to construct an initial approximation
+of the hull, while any extra points found during the construction
+of the hull is added to this list.
+Any equality found in this way that expresses an integer division
+as an \emph{integer} affine combination of other variables is
+propagated to the main tableau, where it is used to eliminate that
+integer division.
+
+\subsection{Experiments}
+
+\autoref{t:comparison} compares the execution times of {\tt isl}
+(with both types of context tableau)
+on some more difficult instances to those of other tools,
+run on an Intel Xeon W3520 @ 2.66GHz.
+Easier problems such as the
+test cases distributed with {\tt Pip\-Lib} can be solved so quickly
+that we would only be measuring overhead such as input/output and conversions
+and not the running time of the actual algorithm.
+We compare the following versions:
+{\tt piplib-1.4.0-5-g0132fd9},
+{\tt barvinok-0.32.1-73-gc5d7751},
+{\tt isl-0.05.1-82-g3a37260}
+and {\tt PPL} version 0.11.2.
+
+The first test case is the following dependence analysis problem
+originating from the Phideo project \shortcite{Verhaegh1995PhD}
+that was communicated to us by Bart Kienhuis:
+\begin{lstlisting}[flexiblecolumns=true,breaklines=true]{}
+lexmax { [j1,j2] -> [i1,i2,i3,i4,i5,i6,i7,i8,i9,i10] : 1 <= i1,j1 <= 8 and 1 <= i2,i3,i4,i5,i6,i7,i8,i9,i10 <= 2 and 1 <= j2 <= 128 and i1-1 = j1-1 and i2-1+2*i3-2+4*i4-4+8*i5-8+16*i6-16+32*i7-32+64*i8-64+128*i9-128+256*i10-256=3*j2-3+66 };
+\end{lstlisting}
+This problem was the main inspiration
+for some of the optimizations in \autoref{s:GBR}.
+The second group of test cases are projections used during counting.
+The first nine of these come from \shortciteN{Seghir2006minimizing}.
+The remaining two come from \shortciteN{Verdoolaege2005experiences} and
+were used to drive the first, Gomory cuts based, implementation
+in {\tt isl}.
+The third and final group of test cases are borrowed from
+\shortciteN{Bygde2010licentiate} and inspired the offline symmetry detection
+of \autoref{s:offline}.  Without symmetry detection, the running times
+are 11s and 5.9s.
+All running times of {\tt barvinok} and {\tt isl} include a conversion
+to disjunctive normal form.  Without this conversion, the final two
+cases can be solved in 0.07s and 0.21s.
+The {\tt PipLib} implementation has some fixed limits and will
+sometimes report the problem to be too complex (TC), while on some other
+problems it will run out of memory (OOM).
+The {\tt barvinok} implementation does not support problems
+with a non-trivial lineality space (line) nor maximization problems (max).
+The Gomory cuts based {\tt isl} implementation was terminated after 1000
+minutes on the first problem.  The gbr version introduces some
+overhead on some of the easier problems, but is overall the clear winner.

+\subsection{Online Symmetry Detection}\label{s:online}
+
+Manual experiments on small instances of the problems of
+\shortciteN{Bygde2010licentiate} and an analysis of the results
+by the approximate MPA method developed by \shortciteN{Bygde2010licentiate}
+have revealed that these problems contain many more symmetries
+than can be detected using the offline method of \autoref{s:offline}.
+In this section, we present an online detection mechanism that has
+not been implemented yet, but that has shown promising results
+in manual applications.
+
+Let us first consider what happens when we do not perform offline
+symmetry detection.  At some point, one of the
+$b_i(\vec p) + \sp {\vec a} {\vec x} \ge 0$ constraints,
+say the $j$th constraint, appears as a column
+variable, say $c_1$, while the other constraints are represented
+as rows of the form $b_i(\vec p) - b_j(\vec p) + c$.
+The context is then split according to the relative order of
+$b_j(\vec p)$ and one of the remaining $b_i(\vec p)$.
+The offline method avoids this split by replacing all $b_i(\vec p)$
+by a single newly introduced parameter that represents the minimum
+of these $b_i(\vec p)$.
+In the online method the split is similarly avoided by the introduction
+of a new parameter.  In particular, a new parameter is introduced
+that represents
+$\left| b_j(\vec p) - b_i(\vec p) \right|_+ =
+\max(b_j(\vec p) - b_i(\vec p), 0)$.
+
+In general, let $r = b(\vec p) + \sp {\vec a} {\vec c}$ be a row
+of the tableau such that the sign of $b(\vec p)$ is indeterminate
+and such that exactly one of the elements of $\vec a$ is a $1$,
+while all remaining elements are non-positive.
+That is, $r = b(\vec p) + c_j - f$ with $f = -\sum_{i\ne j} a_i c_i \ge 0$.
+We introduce a new parameter $t$ with
+context constraints $t \ge -b(\vec p)$ and $t \ge 0$ and replace
+the column variable $c_j$ by $c' + t$.  The row $r$ is now equal
+to $b(\vec p) + t + c' - f$.  The constant term of this row is always
+non-negative because any negative value of $b(\vec p)$ is compensated
+by $t \ge -b(\vec p)$ while and non-negative value remains non-negative
+because $t \ge 0$.
+
+We need to show that this transformation does not eliminate any valid
+solutions and that it does not introduce any spurious solutions.
+Given a valid solution for the original problem, we need to find
+a non-negative value of $c'$ satisfying the constraints.
+If $b(\vec p) \ge 0$, we can take $t = 0$ so that
+$c' = c_j - t = c_j \ge 0$.
+If $b(\vec p) < 0$, we can take $t = -b(\vec p)$.
+Since $r = b(\vec p) + c_j - f \ge 0$ and $f \ge 0$, we have 
+$c' = c_j + b(\vec p) \ge 0$.
+Note that these choices amount to plugging in
+$t = \left|-b(\vec p)\right|_+ = \max(-b(\vec p), 0)$.
+Conversely, given a solution to the new problem, we need to find
+a non-negative value of $c_j$, but this is easy since $c_j = c' + t$
+and both of these are non-negative.
+
+Plugging in $t = \max(-b(\vec p), 0)$ can be performed as in
+\autoref{s:post}, but, as in the case of offline symmetry detection,
+it may be better to provide a direct representation for such
+expressions in the internal representation of sets and relations
+or at least in a quast-like output format.

+
+\section{Transitive Closure}
+
+\subsection{Introduction}
+
+\begin{definition}[Power of a Relation]
+Let $R \in \Z^n \to 2^{\Z^{d+d}}$ be a relation and
+$k \in \Z_{\ge 1}$
+a positive number, then power $k$ of relation $R$ is defined as
+\begin{equation}
+\label{eq:transitive:power}
+R^k \coloneqq
+\begin{cases}
+R & \text{if $k = 1$}
+\\
+R \circ R^{k-1} & \text{if $k \ge 2$}
+.
+\end{cases}
+\end{equation}
+\end{definition}
+
+\begin{definition}[Transitive Closure of a Relation]
+Let $R \in \Z^n \to 2^{\Z^{d+d}}$ be a relation,
+then the transitive closure $R^+$ of $R$ is the union
+of all positive powers of $R$,
+$$
+R^+ \coloneqq \bigcup_{k \ge 1} R^k
+.
+$$
+\end{definition}
+Alternatively, the transitive closure may be defined
+inductively as
+\begin{equation}
+\label{eq:transitive:inductive}
+R^+ \coloneqq R \cup \left(R \circ R^+\right)
+.
+\end{equation}
+
+Since the transitive closure of a polyhedral relation
+may no longer be a polyhedral relation \shortcite{Kelly1996closure},
+we can, in the general case, only compute an approximation
+of the transitive closure.
+Whereas \shortciteN{Kelly1996closure} compute underapproximations,
+we, like \shortciteN{Beletska2009}, compute overapproximations.
+That is, given a relation $R$, we will compute a relation $T$
+such that $R^+ \subseteq T$.  Of course, we want this approximation
+to be as close as possible to the actual transitive closure
+$R^+$ and we want to detect the cases where the approximation is
+exact, i.e., where $T = R^+$.
+
+For computing an approximation of the transitive closure of $R$,
+we follow the same general strategy as \shortciteN{Beletska2009}
+and first compute an approximation of $R^k$ for $k \ge 1$ and then project
+out the parameter $k$ from the resulting relation.
+
+\begin{example}
+As a trivial example, consider the relation
+$R = \{\, x \to x + 1 \,\}$.  The $k$th power of this map
+for arbitrary $k$ is
+$$
+R^k = k \mapsto \{\, x \to x + k \mid k \ge 1 \,\}
+.
+$$
+The transitive closure is then
+$$
+\begin{aligned}
+R^+ & = \{\, x \to y \mid \exists k \in \Z_{\ge 1} : y = x + k \,\}
+\\
+& = \{\, x \to y \mid y \ge x + 1 \,\}
+.
+\end{aligned}
+$$
+\end{example}
+
+\subsection{Computing an Approximation of $R^k$}
+\label{s:power}
+
+There are some special cases where the computation of $R^k$ is very easy.
+One such case is that where $R$ does not compose with itself,
+i.e., $R \circ R = \emptyset$ or $\domain R \cap \range R = \emptyset$.
+In this case, $R^k$ is only non-empty for $k=1$ where it is equal
+to $R$ itself.
+
+In general, it is impossible to construct a closed form
+of $R^k$ as a polyhedral relation.
+We will therefore need to make some approximations.
+As a first approximations, we will consider each of the basic
+relations in $R$ as simply adding one or more offsets to a domain element
+to arrive at an image element and ignore the fact that some of these
+offsets may only be applied to some of the domain elements.
+That is, we will only consider the difference set $\Delta\,R$ of the relation.
+In particular, we will first construct a collection $P$ of paths
+that move through
+a total of $k$ offsets and then intersect domain and range of this
+collection with those of $R$.
+That is, 
+\begin{equation}
+\label{eq:transitive:approx}
+K = P \cap \left(\domain R \to \range R\right)
+,
+\end{equation}
+with
+\begin{equation}
+\label{eq:transitive:path}
+P = \vec s \mapsto \{\, \vec x \to \vec y \mid
+\exists k_i \in \Z_{\ge 0}, \vec\delta_i \in k_i \, \Delta_i(\vec s) :
+\vec y = \vec x + \sum_i \vec\delta_i
+\wedge
+\sum_i k_i = k > 0
+\,\}
+\end{equation}
+and with $\Delta_i$ the basic sets that compose
+the difference set $\Delta\,R$.
+Note that the number of basic sets $\Delta_i$ need not be
+the same as the number of basic relations in $R$.
+Also note that since addition is commutative, it does not
+matter in which order we add the offsets and so we are allowed
+to group them as we did in \eqref{eq:transitive:path}.
+
+If all the $\Delta_i$s are singleton sets
+$\Delta_i = \{\, \vec \delta_i \,\}$ with $\vec \delta_i \in \Z^d$,
+then \eqref{eq:transitive:path} simplifies to
+\begin{equation}
+\label{eq:transitive:singleton}
+P = \{\, \vec x \to \vec y \mid
+\exists k_i \in \Z_{\ge 0} :
+\vec y = \vec x + \sum_i k_i \, \vec \delta_i
+\wedge
+\sum_i k_i = k > 0
+\,\}
+\end{equation}
+and then the approximation computed in \eqref{eq:transitive:approx}
+is essentially the same as that of \shortciteN{Beletska2009}.
+If some of the $\Delta_i$s are not singleton sets or if
+some of $\vec \delta_i$s are parametric, then we need
+to resort to further approximations.
+
+To ease both the exposition and the implementation, we will for
+the remainder of this section work with extended offsets
+$\Delta_i' = \Delta_i \times \{\, 1 \,\}$.
+That is, each offset is extended with an extra coordinate that is
+set equal to one.  The paths constructed by summing such extended
+offsets have the length encoded as the difference of their
+final coordinates.  The path $P'$ can then be decomposed into
+paths $P_i'$, one for each $\Delta_i$,
+\begin{equation}
+\label{eq:transitive:decompose}
+P' = \left(
+(P_m' \cup \identity) \circ \cdots \circ
+(P_2' \cup \identity) \circ
+(P_1' \cup \identity)
+\right) \cap
+\{\,
+\vec x' \to \vec y' \mid y_{d+1} - x_{d+1} = k > 0
+\,\}
+,
+\end{equation}
+with
+$$
+P_i' = \vec s \mapsto \{\, \vec x' \to \vec y' \mid
+\exists k \in \Z_{\ge 1}, \vec \delta \in k \, \Delta_i'(\vec s) :
+\vec y' = \vec x' + \vec \delta
+\,\}
+.
+$$
+Note that each $P_i'$ contains paths of length at least one.
+We therefore need to take the union with the identity relation
+when composing the $P_i'$s to allow for paths that do not contain
+any offsets from one or more $\Delta_i'$.
+The path that consists of only identity relations is removed
+by imposing the constraint $y_{d+1} - x_{d+1} > 0$.
+Taking the union with the identity relation means that
+that the relations we compose in \eqref{eq:transitive:decompose}
+each consist of two basic relations.  If there are $m$
+disjuncts in the input relation, then a direct application
+of the composition operation may therefore result in a relation
+with $2^m$ disjuncts, which is prohibitively expensive.
+It is therefore crucial to apply coalescing (\autoref{s:coalescing})
+after each composition.
+
+Let us now consider how to compute an overapproximation of $P_i'$.
+Those that correspond to singleton $\Delta_i$s are grouped together
+and handled as in \eqref{eq:transitive:singleton}.
+Note that this is just an optimization.  The procedure described
+below would produce results that are at least as accurate.
+For simplicity, we first assume that no constraint in $\Delta_i'$
+involves any existentially quantified variables.
+We will return to existentially quantified variables at the end
+of this section.
+Without existentially quantified variables, we can classify
+the constraints of $\Delta_i'$ as follows
+\begin{enumerate}
+\item non-parametric constraints
+\begin{equation}
+\label{eq:transitive:non-parametric}
+A_1 \vec x + \vec c_1 \geq \vec 0
+\end{equation}
+\item purely parametric constraints
+\begin{equation}
+\label{eq:transitive:parametric}
+B_2 \vec s + \vec c_2 \geq \vec 0
+\end{equation}
+\item negative mixed constraints
+\begin{equation}
+\label{eq:transitive:mixed}
+A_3 \vec x + B_3 \vec s + \vec c_3 \geq \vec 0
+\end{equation}
+such that for each row $j$ and for all $\vec s$,
+$$
+\Delta_i'(\vec s) \cap
+\{\, \vec \delta' \mid B_{3,j} \vec s + c_{3,j} > 0 \,\}
+= \emptyset
+$$
+\item positive mixed constraints
+$$
+A_4 \vec x + B_4 \vec s + \vec c_4 \geq \vec 0
+$$
+such that for each row $j$, there is at least one $\vec s$ such that
+$$
+\Delta_i'(\vec s) \cap
+\{\, \vec \delta' \mid B_{4,j} \vec s + c_{4,j} > 0 \,\}
+\ne \emptyset
+$$
+\end{enumerate}
+We will use the following approximation $Q_i$ for $P_i'$:
+\begin{equation}
+\label{eq:transitive:Q}
+\begin{aligned}
+Q_i = \vec s \mapsto
+\{\,
+\vec x' \to \vec y'
+\mid {} & \exists k \in \Z_{\ge 1}, \vec f \in \Z^d :
+\vec y' = \vec x' + (\vec f, k)
+\wedge {}
+\\
+&
+A_1 \vec f + k \vec c_1 \geq \vec 0
+\wedge
+B_2 \vec s + \vec c_2 \geq \vec 0
+\wedge
+A_3 \vec f + B_3 \vec s + \vec c_3 \geq \vec 0
+\,\}
+.
+\end{aligned}
+\end{equation}
+To prove that $Q_i$ is indeed an overapproximation of $P_i'$,
+we need to show that for every $\vec s \in \Z^n$, for every
+$k \in \Z_{\ge 1}$ and for every $\vec f \in k \, \Delta_i(\vec s)$
+we have that
+$(\vec f, k)$ satisfies the constraints in \eqref{eq:transitive:Q}.
+If $\Delta_i(\vec s)$ is non-empty, then $\vec s$ must satisfy
+the constraints in \eqref{eq:transitive:parametric}.
+Each element $(\vec f, k) \in k \, \Delta_i'(\vec s)$ is a sum
+of $k$ elements $(\vec f_j, 1)$ in $\Delta_i'(\vec s)$.
+Each of these elements satisfies the constraints in
+\eqref{eq:transitive:non-parametric}, i.e.,
+$$
+\left[
+\begin{matrix}
+A_1 & \vec c_1
+\end{matrix}
+\right]
+\left[
+\begin{matrix}
+\vec f_j \\ 1
+\end{matrix}
+\right]
+\ge \vec 0
+.
+$$
+The sum of these elements therefore satisfies the same set of inequalities,
+i.e., $A_1 \vec f + k \vec c_1 \geq \vec 0$.
+Finally, the constraints in \eqref{eq:transitive:mixed} are such
+that for any $\vec s$ in the parameter domain of $\Delta$,
+we have $-\vec r(\vec s) \coloneqq B_3 \vec s + \vec c_3 \le \vec 0$,
+i.e., $A_3 \vec f_j \ge \vec r(\vec s) \ge \vec 0$
+and therefore also $A_3 \vec f \ge \vec r(\vec s)$.
+Note that if there are no mixed constraints and if the
+rational relaxation of $\Delta_i(\vec s)$, i.e.,
+$\{\, \vec x \in \Q^d \mid A_1 \vec x + \vec c_1 \ge \vec 0\,\}$,
+has integer vertices, then the approximation is exact, i.e.,
+$Q_i = P_i'$.  In this case, the vertices of $\Delta'_i(\vec s)$
+generate the rational cone
+$\{\, \vec x' \in \Q^{d+1} \mid \left[
+\begin{matrix}
+A_1 & \vec c_1
+\end{matrix}
+\right] \vec x' \,\}$ and therefore $\Delta'_i(\vec s)$ is
+a Hilbert basis of this cone \shortcite[Theorem~16.4]{Schrijver1986}.
+
+Note however that, as pointed out by \shortciteN{DeSmet2010personal},
+if there \emph{are} any mixed constraints, then the above procedure may
+not compute the most accurate affine approximation of
+$k \, \Delta_i(\vec s)$ with $k \ge 1$.
+In particular, we only consider the negative mixed constraints that
+happen to appear in the description of $\Delta_i(\vec s)$, while we
+should instead consider \emph{all} valid such constraints.
+It is also sufficient to consider those constraints because any
+constraint that is valid for $k \, \Delta_i(\vec s)$ is also
+valid for $1 \, \Delta_i(\vec s) = \Delta_i(\vec s)$.
+Take therefore any constraint
+$\spv a x + \spv b s + c \ge 0$ valid for $\Delta_i(\vec s)$.
+This constraint is also valid for $k \, \Delta_i(\vec s)$ iff
+$k \, \spv a x + \spv b s + c \ge 0$.
+If $\spv b s + c$ can attain any positive value, then $\spv a x$
+may be negative for some elements of $\Delta_i(\vec s)$.
+We then have $k \, \spv a x < \spv a x$ for $k > 1$ and so the constraint
+is not valid for $k \, \Delta_i(\vec s)$.
+We therefore need to impose $\spv b s + c \le 0$ for all values
+of $\vec s$ such that $\Delta_i(\vec s)$ is non-empty, i.e.,
+$\vec b$ and $c$ need to be such that $- \spv b s - c \ge 0$ is a valid
+constraint of $\Delta_i(\vec s)$.  That is, $(\vec b, c)$ are the opposites
+of the coefficients of a valid constraint of $\Delta_i(\vec s)$.
+The approximation of $k \, \Delta_i(\vec s)$ can therefore be obtained
+using three applications of Farkas' lemma.  The first obtains the coefficients
+of constraints valid for $\Delta_i(\vec s)$.  The second obtains
+the coefficients of constraints valid for the projection of $\Delta_i(\vec s)$
+onto the parameters.  The opposite of the second set is then computed
+and intersected with the first set.  The result is the set of coefficients
+of constraints valid for $k \, \Delta_i(\vec s)$.  A final application
+of Farkas' lemma is needed to obtain the approximation of
+$k \, \Delta_i(\vec s)$ itself.
+
+\begin{example}
+Consider the relation
+$$
+n \to \{\, (x, y) \to (1 + x, 1 - n + y) \mid n \ge 2 \,\}
+.
+$$
+The difference set of this relation is
+$$
+\Delta = n \to \{\, (1, 1 - n) \mid n \ge 2 \,\}
+.
+$$
+Using our approach, we would only consider the mixed constraint
+$y - 1 + n \ge 0$, leading to the following approximation of the
+transitive closure:
+$$
+n \to \{\, (x, y) \to (o_0, o_1) \mid n \ge 2 \wedge o_1 \le 1 - n + y \wedge o_0 \ge 1 + x \,\}
+.
+$$
+If, instead, we apply Farkas's lemma to $\Delta$, i.e.,
+\begin{verbatim}
+D := [n] -> { [1, 1 - n] : n >= 2 };
+CD := coefficients D;
+CD;
+\end{verbatim}
+we obtain
+\begin{verbatim}
+{ rat: coefficients[[c_cst, c_n] -> [i2, i3]] : i3 <= c_n and
+  i3 <= c_cst + 2c_n + i2 }
+\end{verbatim}
+The pure-parametric constraints valid for $\Delta$,
+\begin{verbatim}
+P := { [a,b] -> [] }(D);
+CP := coefficients P;
+CP;
+\end{verbatim}
+are
+\begin{verbatim}
+{ rat: coefficients[[c_cst, c_n] -> []] : c_n >= 0 and 2c_n >= -c_cst }
+\end{verbatim}
+Negating these coefficients and intersecting with \verb+CD+,
+\begin{verbatim}
+NCP := { rat: coefficients[[a,b] -> []]
+              -> coefficients[[-a,-b] -> []] }(CP);
+CK := wrap((unwrap CD) * (dom (unwrap NCP)));
+CK;
+\end{verbatim}
+we obtain
+\begin{verbatim}
+{ rat: [[c_cst, c_n] -> [i2, i3]] : i3 <= c_n and
+  i3 <= c_cst + 2c_n + i2 and c_n <= 0 and 2c_n <= -c_cst }
+\end{verbatim}
+The approximation for $k\,\Delta$,
+\begin{verbatim}
+K := solutions CK;
+K;
+\end{verbatim}
+is then
+\begin{verbatim}
+[n] -> { rat: [i0, i1] : i1 <= -i0 and i0 >= 1 and i1 <= 2 - n - i0 }
+\end{verbatim}
+Finally, the computed approximation for $R^+$,
+\begin{verbatim}
+T := unwrap({ [dx,dy] -> [[x,y] -> [x+dx,y+dy]] }(K));
+R := [n] -> { [x,y] -> [x+1,y+1-n] : n >= 2 };
+T := T * ((dom R) -> (ran R));
+T;
+\end{verbatim}
+is
+\begin{verbatim}
+[n] -> { [x, y] -> [o0, o1] : o1 <= x + y - o0 and
+         o0 >= 1 + x and o1 <= 2 - n + x + y - o0 and n >= 2 }
+\end{verbatim}
+\end{example}
+
+Existentially quantified variables can be handled by
+classifying them into variables that are uniquely
+determined by the parameters, variables that are independent
+of the parameters and others.  The first set can be treated
+as parameters and the second as variables.  Constraints involving
+the other existentially quantified variables are removed.
+
+\begin{example}
+Consider the relation
+$$
+R =
+n \to \{\, x \to y \mid \exists \, \alpha_0, \alpha_1: 7\alpha_0 = -2 + n \wedge 5\alpha_1 = -1 - x + y \wedge y \ge 6 + x \,\}
+.
+$$
+The difference set of this relation is
+$$
+\Delta = \Delta \, R =
+n \to \{\, x \mid \exists \, \alpha_0, \alpha_1: 7\alpha_0 = -2 + n \wedge 5\alpha_1 = -1 + x \wedge x \ge 6 \,\}
+.
+$$
+The existentially quantified variables can be defined in terms
+of the parameters and variables as
+$$
+\alpha_0 = \floor{\frac{-2 + n}7}
+\qquad
+\text{and}
+\qquad
+\alpha_1 = \floor{\frac{-1 + x}5}
+.
+$$
+$\alpha_0$ can therefore be treated as a parameter,
+while $\alpha_1$ can be treated as a variable.
+This in turn means that $7\alpha_0 = -2 + n$ can be treated as
+a purely parametric constraint, while the other two constraints are
+non-parametric.
+The corresponding $Q$~\eqref{eq:transitive:Q} is therefore
+$$
+\begin{aligned}
+n \to \{\, (x,z) \to (y,w) \mid
+\exists\, \alpha_0, \alpha_1, k, f : {} &
+k \ge 1 \wedge
+y = x + f \wedge
+w = z + k \wedge {} \\
+&
+7\alpha_0 = -2 + n \wedge
+5\alpha_1 = -k + x \wedge
+x \ge 6 k
+\,\}
+.
+\end{aligned}
+$$
+Projecting out the final coordinates encoding the length of the paths,
+results in the exact transitive closure
+$$
+R^+ =
+n \to \{\, x \to y \mid \exists \, \alpha_0, \alpha_1: 7\alpha_1 = -2 + n \wedge 6\alpha_0 \ge -x + y \wedge 5\alpha_0 \le -1 - x + y \,\}
+.
+$$
+\end{example}
+
+The fact that we ignore some impure constraints clearly leads
+to a loss of accuracy.  In some cases, some of this loss can be recovered
+by not considering the parameters in a special way.
+That is, instead of considering the set
+$$
+\Delta = \diff R =
+\vec s \mapsto
+\{\, \vec \delta \in \Z^{d} \mid \exists \vec x \to \vec y \in R :
+\vec \delta = \vec y - \vec x
+\,\}
+$$
+we consider the set
+$$
+\Delta' = \diff R' =
+\{\, \vec \delta \in \Z^{n+d} \mid \exists
+(\vec s, \vec x) \to (\vec s, \vec y) \in R' :
+\vec \delta = (\vec s - \vec s, \vec y - \vec x)
+\,\}
+.
+$$
+The first $n$ coordinates of every element in $\Delta'$ are zero.
+Projecting out these zero coordinates from $\Delta'$ is equivalent
+to projecting out the parameters in $\Delta$.
+The result is obviously a superset of $\Delta$, but all its constraints
+are of type \eqref{eq:transitive:non-parametric} and they can therefore
+all be used in the construction of $Q_i$.
+
+\begin{example}
+Consider the relation
+$$
+% [n] -> { [x, y] -> [1 + x, 1 - n + y] | n >= 2 }
+R = n \to \{\, (x, y) \to (1 + x, 1 - n + y) \mid n \ge 2 \,\}
+.
+$$
+We have
+$$
+\diff R = n \to \{\, (1, 1 - n) \mid n \ge 2 \,\}
+$$
+and so, by treating the parameters in a special way, we obtain
+the following approximation for $R^+$:
+$$
+n \to \{\, (x, y) \to (x', y') \mid n \ge 2 \wedge y' \le 1 - n + y \wedge x' \ge 1 + x \,\}
+.
+$$
+If we consider instead
+$$
+R' = \{\, (n, x, y) \to (n, 1 + x, 1 - n + y) \mid n \ge 2 \,\}
+$$
+then
+$$
+\diff R' = \{\, (0, 1, y) \mid y \le -1 \,\}
+$$
+and we obtain the approximation
+$$
+n \to \{\, (x, y) \to (x', y') \mid n \ge 2 \wedge x' \ge 1 + x \wedge y' \le x + y - x' \,\}
+.
+$$
+If we consider both $\diff R$ and $\diff R'$, then we obtain
+$$
+n \to \{\, (x, y) \to (x', y') \mid n \ge 2 \wedge y' \le 1 - n + y \wedge x' \ge 1 + x \wedge y' \le x + y - x' \,\}
+.
+$$
+Note, however, that this is not the most accurate affine approximation that
+can be obtained.  That would be
+$$
+n \to \{\, (x, y) \to (x', y') \mid y' \le 2 - n + x + y - x' \wedge n \ge 2 \wedge x' \ge 1 + x \,\}
+.
+$$
+\end{example}
+
+\subsection{Checking Exactness}
+
+The approximation $T$ for the transitive closure $R^+$ can be obtained
+by projecting out the parameter $k$ from the approximation $K$
+\eqref{eq:transitive:approx} of the power $R^k$.
+Since $K$ is an overapproximation of $R^k$, $T$ will also be an
+overapproximation of $R^+$.
+To check whether the results are exact, we need to consider two
+cases depending on whether $R$ is {\em cyclic}, where $R$ is defined
+to be cyclic if $R^+$ maps any element to itself, i.e.,
+$R^+ \cap \identity \ne \emptyset$.
+If $R$ is acyclic, then the inductive definition of
+\eqref{eq:transitive:inductive} is equivalent to its completion,
+i.e.,
+$$
+R^+ = R \cup \left(R \circ R^+\right)
+$$
+is a defining property.
+Since $T$ is known to be an overapproximation, we only need to check
+whether
+$$
+T \subseteq R \cup \left(R \circ T\right)
+.
+$$
+This is essentially Theorem~5 of \shortciteN{Kelly1996closure}.
+The only difference is that they only consider lexicographically
+forward relations, a special case of acyclic relations.
+
+If, on the other hand, $R$ is cyclic, then we have to resort
+to checking whether the approximation $K$ of the power is exact.
+Note that $T$ may be exact even if $K$ is not exact, so the check
+is sound, but incomplete.
+To check exactness of the power, we simply need to check
+\eqref{eq:transitive:power}.  Since again $K$ is known
+to be an overapproximation, we only need to check whether
+$$
+\begin{aligned}
+K'|_{y_{d+1} - x_{d+1} = 1} & \subseteq R'
+\\
+K'|_{y_{d+1} - x_{d+1} \ge 2} & \subseteq R' \circ K'|_{y_{d+1} - x_{d+1} \ge 1}
+,
+\end{aligned}
+$$
+where $R' = \{\, \vec x' \to \vec y' \mid \vec x \to \vec y \in R
+\wedge y_{d+1} - x_{d+1} = 1\,\}$, i.e., $R$ extended with path
+lengths equal to 1.
+
+All that remains is to explain how to check the cyclicity of $R$.
+Note that the exactness on the power is always sound, even
+in the acyclic case, so we only need to be careful that we find
+all cyclic cases.  Now, if $R$ is cyclic, i.e.,
+$R^+ \cap \identity \ne \emptyset$, then, since $T$ is
+an overapproximation of $R^+$, also
+$T \cap \identity \ne \emptyset$.  This in turn means
+that $\Delta \, K'$ contains a point whose first $d$ coordinates
+are zero and whose final coordinate is positive.
+In the implementation we currently perform this test on $P'$ instead of $K'$.
+Note that if $R^+$ is acyclic and $T$ is not, then the approximation
+is clearly not exact and the approximation of the power $K$
+will not be exact either.
+
+\subsection{Decomposing $R$ into strongly connected components}
+
+If the input relation $R$ is a union of several basic relations
+that can be partially ordered
+then the accuracy of the approximation may be improved by computing
+an approximation of each strongly connected components separately.
+For example, if $R = R_1 \cup R_2$ and $R_1 \circ R_2 = \emptyset$,
+then we know that any path that passes through $R_2$ cannot later
+pass through $R_1$, i.e.,
+\begin{equation}
+\label{eq:transitive:components}
+R^+ = R_1^+ \cup R_2^+ \cup \left(R_2^+ \circ R_1^+\right)
+.
+\end{equation}
+We can therefore compute (approximations of) transitive closures
+of $R_1$ and $R_2$ separately.
+Note, however, that the condition $R_1 \circ R_2 = \emptyset$
+is actually too strong.
+If $R_1 \circ R_2$ is a subset of $R_2 \circ R_1$
+then we can reorder the segments
+in any path that moves through both $R_1$ and $R_2$ to
+first move through $R_1$ and then through $R_2$.
+
+This idea can be generalized to relations that are unions
+of more than two basic relations by constructing the
+strongly connected components in the graph with as vertices
+the basic relations and an edge between two basic relations
+$R_i$ and $R_j$ if $R_i$ needs to follow $R_j$ in some paths.
+That is, there is an edge from $R_i$ to $R_j$ iff
+\begin{equation}
+\label{eq:transitive:edge}
+R_i \circ R_j
+\not\subseteq
+R_j \circ R_i
+.
+\end{equation}
+The components can be obtained from the graph by applying
+Tarjan's algorithm \shortcite{Tarjan1972}.
+
+In practice, we compute the (extended) powers $K_i'$ of each component
+separately and then compose them as in \eqref{eq:transitive:decompose}.
+Note, however, that in this case the order in which we apply them is
+important and should correspond to a topological ordering of the
+strongly connected components.  Simply applying Tarjan's
+algorithm will produce topologically sorted strongly connected components.
+The graph on which Tarjan's algorithm is applied is constructed on-the-fly.
+That is, whenever the algorithm checks if there is an edge between
+two vertices, we evaluate \eqref{eq:transitive:edge}.
+The exactness check is performed on each component separately.
+If the approximation turns out to be inexact for any of the components,
+then the entire result is marked inexact and the exactness check
+is skipped on the components that still need to be handled.
+
+It should be noted that \eqref{eq:transitive:components}
+is only valid for exact transitive closures.
+If overapproximations are computed in the right hand side, then the result will
+still be an overapproximation of the left hand side, but this result
+may not be transitively closed.  If we only separate components based
+on the condition $R_i \circ R_j = \emptyset$, then there is no problem,
+as this condition will still hold on the computed approximations
+of the transitive closures.  If, however, we have exploited
+\eqref{eq:transitive:edge} during the decomposition and if the
+result turns out not to be exact, then we check whether
+the result is transitively closed.  If not, we recompute
+the transitive closure, skipping the decomposition.
+Note that testing for transitive closedness on the result may
+be fairly expensive, so we may want to make this check
+configurable.

+\begin{aligned}
+R_1 &= n \mapsto \{\, (i,j) \to (i+3,j) \mid

+j \le n - 1\,\}
+.
+\end{aligned}
+$$
+The figure shows this relation for $n = 7$.
+Both
+$R_3 \circ R_1 \subseteq R_1 \circ R_3$
+and
+$R_3 \circ R_2 \subseteq R_2 \circ R_3$,
+which the reader can verify using the {\tt iscc} calculator:
+\begin{verbatim}
+R1 := [n] -> { [i,j] -> [i+3,j] : i <= 2 j - 4 and i <= n - 3 and
+                                  j <= 2 i - 1 and j <= n };
+R2 := [n] -> { [i,j] -> [i,j+3] : i <= 2 j - 1 and i <= n and
+                                  j <= 2 i - 4 and j <= n - 3 };

+(R1 . R3) - (R3 . R1);
+(R2 . R3) - (R3 . R2);
+\end{verbatim}
+$R_3$ can therefore be moved forward in any path.
+For the other two basic relations, we have both
+$R_2 \circ R_1 \not\subseteq R_1 \circ R_2$
+and
+$R_1 \circ R_2 \not\subseteq R_2 \circ R_1$
+and so $R_1$ and $R_2$ form a strongly connected component.
+By computing the power of $R_3$ and $R_1 \cup R_2$ separately
+and composing the results, the power of $R$ can be computed exactly
+using \eqref{eq:transitive:singleton}.
+As explained by \shortciteN{Beletska2009}, applying the same formula
+to $R$ directly, without a decomposition, would result in
+an overapproximation of the power.
+\end{example}
+
+\subsection{Partitioning the domains and ranges of $R$}
+
+The algorithm of \autoref{s:power} assumes that the input relation $R$
+can be treated as a union of translations.
+This is a reasonable assumption if $R$ maps elements of a given
+abstract domain to the same domain.
+However, if $R$ is a union of relations that map between different
+domains, then this assumption no longer holds.
+In particular, when an entire dependence graph is encoded
+in a single relation, as is done by, e.g.,
+\shortciteN[Section~6.1]{Barthou2000MSE}, then it does not make
+sense to look at differences between iterations of different domains.
+Now, arguably, a modified Floyd-Warshall algorithm should
+be applied to the dependence graph, as advocated by
+\shortciteN{Kelly1996closure}, with the transitive closure operation
+only being applied to relations from a given domain to itself.
+However, it is also possible to detect disjoint domains and ranges
+and to apply Floyd-Warshall internally.

+,
+$$
+apply \autoref{a:Floyd} and return the union of all resulting
+$R_{pq}$ as the transitive closure of $R$.
+Each iteration of the $r$-loop in \autoref{a:Floyd} updates
+all relations $R_{pq}$ to include paths that go from $p$ to $r$,
+possibly stay there for a while, and then go from $r$ to $q$.
+Note that paths that ``stay in $r$'' include all paths that
+pass through earlier vertices since $R_{rr}$ itself has been updated
+accordingly in previous iterations of the outer loop.
+In principle, it would be sufficient to use the $R_{pr}$
+and $R_{rq}$ computed in the previous iteration of the
+$r$-loop in Line~\ref{l:Floyd:update}.
+However, from an implementation perspective, it is easier
+to allow either or both of these to have been updated
+in the same iteration of the $r$-loop.
+This may result in duplicate paths, but these can usually
+be removed by coalescing (\autoref{s:coalescing}) the result of the union
+in Line~\ref{l:Floyd:update}, which should be done in any case.
+The transitive closure in Line~\ref{l:Floyd:closure}
+is performed using a recursive call.  This recursive call
+includes the partitioning step, but the resulting partition will
+usually be a singleton.
+The result of the recursive call will either be exact or an
+overapproximation.  The final result of Floyd-Warshall is therefore
+also exact or an overapproximation.

+\caption{The relation (solid arrows) on the right of Figure~1 of
+\protect\shortciteN{Beletska2009} and its transitive closure}
+\label{f:COCOA:1}
+\end{figure}
+\begin{example}
+Consider the relation on the right of Figure~1 of
+\shortciteN{Beletska2009},
+reproduced in \autoref{f:COCOA:1}.
+This relation can be described as
+$$
+\begin{aligned}
+\{\, (x, y) \to (x_2, y_2) \mid {} & (3y = 2x \wedge x_2 = x \wedge 3y_2 = 3 + 2x \wedge x \ge 0 \wedge x \le 3) \vee {} \\
+& (x_2 = 1 + x \wedge y_2 = y \wedge x \ge 0 \wedge 3y \ge 2 + 2x \wedge x \le 2 \wedge 3y \le 3 + 2x) \,\}
+.
+\end{aligned}
+$$
+Note that the domain of the upward relation overlaps with the range
+of the rightward relation and vice versa, but that the domain
+of neither relation overlaps with its own range or the domain of
+the other relation.
+The domains and ranges can therefore be partitioned into two parts,
+$P_0$ and $P_1$, shown as the white and black dots in \autoref{f:COCOA:1},
+respectively.
+Initially, we have
+$$
+\begin{aligned}
+R_{00} & = \emptyset
+\\
+R_{01} & = 
+\{\, (x, y) \to (x+1, y) \mid 
+(x \ge 0 \wedge 3y \ge 2 + 2x \wedge x \le 2 \wedge 3y \le 3 + 2x) \,\}
+\\
+R_{10} & =
+\{\, (x, y) \to (x_2, y_2) \mid (3y = 2x \wedge x_2 = x \wedge 3y_2 = 3 + 2x \wedge x \ge 0 \wedge x \le 3) \,\}
+\\
+R_{11} & = \emptyset
+.
+\end{aligned}
+$$
+In the first iteration, $R_{00}$ remains the same ($\emptyset^+ = \emptyset$).
+$R_{01}$ and $R_{10}$ are therefore also unaffected, but
+$R_{11}$ is updated to include $R_{01} \circ R_{10}$, i.e.,
+the dashed arrow in the figure.
+This new $R_{11}$ is obviously transitively closed, so it is not
+changed in the second iteration and it does not have an effect
+on $R_{01}$ and $R_{10}$.  However, $R_{00}$ is updated to
+include $R_{10} \circ R_{01}$, i.e., the dotted arrow in the figure.
+The transitive closure of the original relation is then equal to
+$R_{00} \cup R_{01} \cup R_{10} \cup R_{11}$.
+\end{example}
+
+\subsection{Incremental Computation}
+\label{s:incremental}
+
+In some cases it is possible and useful to compute the transitive closure
+of union of basic relations incrementally.  In particular,
+if $R$ is a union of $m$ basic maps,
+$$
+R = \bigcup_j R_j
+,
+$$
+then we can pick some $R_i$ and compute the transitive closure of $R$ as
+\begin{equation}
+\label{eq:transitive:incremental}
+R^+ = R_i^+ \cup
+\left(
+\bigcup_{j \ne i}
+R_i^* \circ R_j \circ R_i^*
+\right)^+
+.
+\end{equation}
+For this approach to be successful, it is crucial that each
+of the disjuncts in the argument of the second transitive
+closure in \eqref{eq:transitive:incremental} be representable
+as a single basic relation, i.e., without a union.
+If this condition holds, then by using \eqref{eq:transitive:incremental},
+the number of disjuncts in the argument of the transitive closure
+can be reduced by one.
+Now, $R_i^* = R_i^+ \cup \identity$, but in some cases it is possible
+to relax the constraints of $R_i^+$ to include part of the identity relation,
+say on domain $D$.  We will use the notation
+${\cal C}(R_i,D) = R_i^+ \cup \identity_D$ to represent
+this relaxed version of $R^+$.
+\shortciteN{Kelly1996closure} use the notation $R_i^?$.
+${\cal C}(R_i,D)$ can be computed by allowing $k$ to attain
+the value $0$ in \eqref{eq:transitive:Q} and by using
+$$
+P \cap \left(D \to D\right)
+$$
+instead of \eqref{eq:transitive:approx}.
+Typically, $D$ will be a strict superset of both $\domain R_i$
+and $\range R_i$.  We therefore need to check that domain
+and range of the transitive closure are part of ${\cal C}(R_i,D)$,
+i.e., the part that results from the paths of positive length ($k \ge 1$),
+are equal to the domain and range of $R_i$.
+If not, then the incremental approach cannot be applied for
+the given choice of $R_i$ and $D$.
+
+In order to be able to replace $R^*$ by ${\cal C}(R_i,D)$
+in \eqref{eq:transitive:incremental}, $D$ should be chosen
+to include both $\domain R$ and $\range R$, i.e., such
+that $\identity_D \circ R_j \circ \identity_D = R_j$ for all $j\ne i$.
+\shortciteN{Kelly1996closure} say that they use
+$D = \domain R_i \cup \range R_i$, but presumably they mean that
+they use $D = \domain R \cup \range R$.
+Now, this expression of $D$ contains a union, so it not directly usable.
+\shortciteN{Kelly1996closure} do not explain how they avoid this union.
+Apparently, in their implementation,
+they are using the convex hull of $\domain R \cup \range R$
+or at least an approximation of this convex hull.
+We use the simple hull (\autoref{s:simple hull}) of $\domain R \cup \range R$.
+
+It is also possible to use a domain $D$ that does {\em not\/}
+include $\domain R \cup \range R$, but then we have to
+compose with ${\cal C}(R_i,D)$ more selectively.
+In particular, if we have
+\begin{equation}
+\label{eq:transitive:right}
+\text{for each $j \ne i$ either }
+\domain R_j \subseteq D \text{ or } \domain R_j \cap \range R_i = \emptyset
+\end{equation}
+and, similarly,
+\begin{equation}
+\label{eq:transitive:left}
+\text{for each $j \ne i$ either }
+\range R_j \subseteq D \text{ or } \range R_j \cap \domain R_i = \emptyset
+\end{equation}
+then we can refine \eqref{eq:transitive:incremental} to
+$$
+R_i^+ \cup
+\left(
+\left(
+\bigcup_{\shortstack{$\scriptstyle\domain R_j \subseteq D $\\
+		     $\scriptstyle\range R_j \subseteq D$}}
+{\cal C} \circ R_j \circ {\cal C}
+\right)
+\cup
+\left(
+\bigcup_{\shortstack{$\scriptstyle\domain R_j \cap \range R_i = \emptyset$\\
+		     $\scriptstyle\range R_j \subseteq D$}}
+\!\!\!\!\!
+{\cal C} \circ R_j
+\right)
+\cup
+\left(
+\bigcup_{\shortstack{$\scriptstyle\domain R_j \subseteq D $\\
+		     $\scriptstyle\range R_j \cap \domain R_i = \emptyset$}}
+\!\!\!\!\!
+R_j \circ {\cal C}
+\right)
+\cup
+\left(
+\bigcup_{\shortstack{$\scriptstyle\domain R_j \cap \range R_i = \emptyset$\\
+		     $\scriptstyle\range R_j \cap \domain R_i = \emptyset$}}
+\!\!\!\!\!
+R_j
+\right)
+\right)^+
+.
+$$
+If only property~\eqref{eq:transitive:right} holds,
+we can use
+$$
+R_i^+ \cup
+\left(
+\left(
+R_i^+ \cup \identity
+\right)
+\circ
+\left(
+\left(
+\bigcup_{\shortstack{$\scriptstyle\domain R_j \subseteq D $}}
+R_j \circ {\cal C}
+\right)
+\cup
+\left(
+\bigcup_{\shortstack{$\scriptstyle\domain R_j \cap \range R_i = \emptyset$}}
+\!\!\!\!\!
+R_j
+\right)
+\right)^+
+\right)
+,
+$$
+while if only property~\eqref{eq:transitive:left} holds,
+we can use
+$$
+R_i^+ \cup
+\left(
+\left(
+\left(
+\bigcup_{\shortstack{$\scriptstyle\range R_j \subseteq D $}}
+{\cal C} \circ R_j
+\right)
+\cup
+\left(
+\bigcup_{\shortstack{$\scriptstyle\range R_j \cap \domain R_i = \emptyset$}}
+\!\!\!\!\!
+R_j
+\right)
+\right)^+
+\circ
+\left(
+R_i^+ \cup \identity
+\right)
+\right)
+.
+$$
+
+It should be noted that if we want the result of the incremental
+approach to be transitively closed, then we can only apply it
+if all of the transitive closure operations involved are exact.
+If, say, the second transitive closure in \eqref{eq:transitive:incremental}
+contains extra elements, then the result does not necessarily contain
+the composition of these extra elements with powers of $R_i$.
+
+\subsection{An {\tt Omega}-like implementation}
+
+While the main algorithm of \shortciteN{Kelly1996closure} is
+designed to compute and underapproximation of the transitive closure,
+the authors mention that they could also compute overapproximations.
+In this section, we describe our implementation of an algorithm
+that is based on their ideas.
+Note that the {\tt Omega} library computes underapproximations
+\shortcite[Section 6.4]{Omega_lib}.
+
+The main tool is Equation~(2) of \shortciteN{Kelly1996closure}.
+The input relation $R$ is first overapproximated by a ``d-form'' relation
+$$
+\{\, \vec i \to \vec j \mid \exists \vec \alpha :
+\vec L \le \vec j - \vec i \le \vec U
+\wedge
+(\forall p : j_p - i_p = M_p \alpha_p)
+\,\}
+,
+$$
+where $p$ ranges over the dimensions and $\vec L$, $\vec U$ and
+$\vec M$ are constant integer vectors.  The elements of $\vec U$
+may be $\infty$, meaning that there is no upper bound corresponding
+to that element, and similarly for $\vec L$.
+Such an overapproximation can be obtained by computing strides,
+lower and upper bounds on the difference set $\Delta \, R$.
+The transitive closure of such a ``d-form'' relation is
+\begin{equation}
+\label{eq:omega}
+\{\, \vec i \to \vec j \mid \exists \vec \alpha, k :
+k \ge 1 \wedge
+k \, \vec L \le \vec j - \vec i \le k \, \vec U
+\wedge
+(\forall p : j_p - i_p = M_p \alpha_p)
+\,\}
+.
+\end{equation}
+The domain and range of this transitive closure are then
+intersected with those of the input relation.
+This is a special case of the algorithm in \autoref{s:power}.
+
+In their algorithm for computing lower bounds, the authors
+use the above algorithm as a substep on the disjuncts in the relation.
+At the end, they say
+\begin{quote}
+If an upper bound is required, it can be calculated in a manner
+similar to that of a single conjunct [sic] relation.
+\end{quote}
+Presumably, the authors mean that a ``d-form'' approximation
+of the whole input relation should be used.
+However, the accuracy can be improved by also trying to
+apply the incremental technique from the same paper,
+which is explained in more detail in \autoref{s:incremental}.
+In this case, ${\cal C}(R_i,D)$ can be obtained by
+allowing the value zero for $k$ in \eqref{eq:omega},
+i.e., by computing
+$$
+\{\, \vec i \to \vec j \mid \exists \vec \alpha, k :
+k \ge 0 \wedge
+k \, \vec L \le \vec j - \vec i \le k \, \vec U
+\wedge
+(\forall p : j_p - i_p = M_p \alpha_p)
+\,\}
+.
+$$
+In our implementation we take as $D$ the simple hull
+(\autoref{s:simple hull}) of $\domain R \cup \range R$.
+To determine whether it is safe to use ${\cal C}(R_i,D)$,
+we check the following conditions, as proposed by
+\shortciteN{Kelly1996closure}:
+${\cal C}(R_i,D) - R_i^+$ is not a union and for each $j \ne i$
+the condition
+$$
+\left({\cal C}(R_i,D) - R_i^+\right)
+\circ
+R_j
+\circ
+\left({\cal C}(R_i,D) - R_i^+\right)
+=
+R_j
+$$
+holds.

+  that a good way to help programmers write efficient programs is to
+  provide them with tools that show them how their programs behave on

+  factor of data-parallel programs and so automatic data layout for
+  HPF programs has been studied by many researchers recently.  The
+  communication volume induced by a data distribution is a good
+  estimator of the efficiency of this data distribution.
+
+  We present here a symbolic method to compute the communication
+  volume generated by a given data distribution during the program
+  writing phase (before compilation). We stay machine-independent to
+  assure portability.  Our goal is to help the programmer understand
+  the data movements its program generates and thus find a good data
+  distribution. Our method is based on parametric polyhedral
+  computations. It can be applied to a large class of regular codes.},

+=head1 Introduction
+
+C<isl> is a thread-safe C library for manipulating
+sets and relations of integer points bounded by affine constraints.
+The descriptions of the sets and relations may involve
+both parameters and existentially quantified variables.
+All computations are performed in exact integer arithmetic
+using C<GMP>.
+The C<isl> library offers functionality that is similar
+to that offered by the C<Omega> and C<Omega+> libraries,
+but the underlying algorithms are in most cases completely different.
+
+The library is by no means complete and some fairly basic
+functionality is still missing.
+Still, even in its current form, the library has been successfully
+used as a backend polyhedral library for the polyhedral
+scanner C<CLooG> and as part of an equivalence checker of
+static affine programs.
+For bug reports, feature requests and questions,
+visit the the discussion group at
+L<http://groups.google.com/group/isl-development>.
+
+=head2 Backward Incompatible Changes
+
+=head3 Changes since isl-0.02
+
+=over
+
+=item * The old printing functions have been deprecated
+and replaced by C<isl_printer> functions, see L<Input and Output>.
+
+=item * Most functions related to dependence analysis have acquired
+an extra C<must> argument.  To obtain the old behavior, this argument
+should be given the value 1.  See L<Dependence Analysis>.
+
+=back
+
+=head3 Changes since isl-0.03
+
+=over
+
+=item * The function C<isl_pw_qpolynomial_fold_add> has been
+renamed to C<isl_pw_qpolynomial_fold_fold>.
+Similarly, C<isl_union_pw_qpolynomial_fold_add> has been
+renamed to C<isl_union_pw_qpolynomial_fold_fold>.
+
+=back
+
+=head3 Changes since isl-0.04
+
+=over
+
+=item * All header files have been renamed from C<isl_header.h>
+to C<isl/header.h>.
+
+=back
+
+=head3 Changes since isl-0.05
+
+=over
+
+=item * The functions C<isl_printer_print_basic_set> and
+C<isl_printer_print_basic_map> no longer print a newline.
+
+=item * The functions C<isl_flow_get_no_source>
+and C<isl_union_map_compute_flow> now return
+the accesses for which no source could be found instead of
+the iterations where those accesses occur.
+
+=item * The functions C<isl_basic_map_identity> and
+C<isl_map_identity> now take a B<map> space as input.  An old call
+C<isl_map_identity(space)> can be rewritten to
+C<isl_map_identity(isl_space_map_from_set(space))>.
+
+=item * The function C<isl_map_power> no longer takes
+a parameter position as input.  Instead, the exponent
+is now expressed as the domain of the resulting relation.
+
+=back
+
+=head3 Changes since isl-0.06
+
+=over
+
+=item * The format of C<isl_printer_print_qpolynomial>'s
+C<ISL_FORMAT_ISL> output has changed.
+Use C<ISL_FORMAT_C> to obtain the old output.
+
+=item * The C<*_fast_*> functions have been renamed to C<*_plain_*>.
+Some of the old names have been kept for backward compatibility,
+but they will be removed in the future.
+
+=back
+
+=head3 Changes since isl-0.07
+
+=over
+
+=item * The function C<isl_pw_aff_max> has been renamed to
+C<isl_pw_aff_union_max>.
+Similarly, the function C<isl_pw_aff_add> has been renamed to
+C<isl_pw_aff_union_add>.
+
+=item * The C<isl_dim> type has been renamed to C<isl_space>
+along with the associated functions.
+Some of the old names have been kept for backward compatibility,
+but they will be removed in the future.
+
+=item * Spaces of maps, sets and parameter domains are now
+treated differently.  The distinction between map spaces and set spaces
+has always been made on a conceptual level, but proper use of such spaces
+was never checked.  Furthermore, up until isl-0.07 there was no way
+of explicitly creating a parameter space.  These can now be created
+directly using C<isl_space_params_alloc> or from other spaces using
+C<isl_space_params>.
+
+=item * The space in which C<isl_aff>, C<isl_pw_aff>, C<isl_qpolynomial>,
+C<isl_pw_qpolynomial>, C<isl_qpolynomial_fold> and C<isl_pw_qpolynomial_fold>
+objects live is now a map space
+instead of a set space.  This means, for example, that the dimensions
+of the domain of an C<isl_aff> are now considered to be of type
+C<isl_dim_in> instead of C<isl_dim_set>.  Extra functions have been
+added to obtain the domain space.  Some of the constructors still
+take a domain space and have therefore been renamed.
+
+=item * The functions C<isl_equality_alloc> and C<isl_inequality_alloc>
+now take an C<isl_local_space> instead of an C<isl_space>.
+An C<isl_local_space> can be created from an C<isl_space>
+using C<isl_local_space_from_space>.
+
+=item * The C<isl_div> type has been removed.  Functions that used
+to return an C<isl_div> now return an C<isl_aff>.
+Note that the space of an C<isl_aff> is that of relation.
+When replacing a call to C<isl_div_get_coefficient> by a call to
+C<isl_aff_get_coefficient> any C<isl_dim_set> argument needs
+to be replaced by C<isl_dim_in>.
+A call to C<isl_aff_from_div> can be replaced by a call
+to C<isl_aff_floor>.
+A call to C<isl_qpolynomial_div(div)> call be replaced by
+the nested call
+
+	isl_qpolynomial_from_aff(isl_aff_floor(div))
+
+The function C<isl_constraint_div> has also been renamed
+to C<isl_constraint_get_div>.
+
+=item * The C<nparam> argument has been removed from
+C<isl_map_read_from_str> and similar functions.
+When reading input in the original PolyLib format,
+the result will have no parameters.
+If parameters are expected, the caller may want to perform
+dimension manipulation on the result.
+
+=back
+
+=head3 Changes since isl-0.09
+
+=over
+
+=item * The C<schedule_split_parallel> option has been replaced
+by the C<schedule_split_scaled> option.
+
+=item * The first argument of C<isl_pw_aff_cond> is now
+an C<isl_pw_aff> instead of an C<isl_set>.
+A call C<isl_pw_aff_cond(a, b, c)> can be replaced by
+
+	isl_pw_aff_cond(isl_set_indicator_function(a), b, c)
+
+=back
+
+=head3 Changes since isl-0.10
+
+=over
+
+=item * The functions C<isl_set_dim_has_lower_bound> and
+C<isl_set_dim_has_upper_bound> have been renamed to
+C<isl_set_dim_has_any_lower_bound> and
+C<isl_set_dim_has_any_upper_bound>.
+The new C<isl_set_dim_has_lower_bound> and
+C<isl_set_dim_has_upper_bound> have slightly different meanings.

+
+=head1 Installation
+
+The source of C<isl> can be obtained either as a tarball
+or from the git repository.  Both are available from
+L<http://freshmeat.net/projects/isl/>.
+The installation process depends on how you obtained
+the source.
+
+=head2 Installation from the git repository
+
+=over
+
+=item 1 Clone or update the repository
+
+The first time the source is obtained, you need to clone
+the repository.
+
+	git clone git://repo.or.cz/isl.git
+
+To obtain updates, you need to pull in the latest changes
+
+	git pull
+
+=item 2 Generate C<configure>
+
+	./autogen.sh
+
+=back
+
+After performing the above steps, continue
+with the L<Common installation instructions>.
+
+=head2 Common installation instructions
+
+=over
+
+=item 1 Obtain C<GMP>
+
+Building C<isl> requires C<GMP>, including its headers files.
+Your distribution may not provide these header files by default
+and you may need to install a package called C<gmp-devel> or something
+similar.  Alternatively, C<GMP> can be built from
+source, available from L<http://gmplib.org/>.
+
+=item 2 Configure
+
+C<isl> uses the standard C<autoconf> C<configure> script.
+To run it, just type
+
+	./configure
+
+optionally followed by some configure options.
+A complete list of options can be obtained by running
+
+	./configure --help
+
+Below we discuss some of the more common options.
+
+C<isl> can optionally use C<piplib>, but no
+C<piplib> functionality is currently used by default.
+The C<--with-piplib> option can
+be used to specify which C<piplib>
+library to use, either an installed version (C<system>),
+an externally built version (C<build>)
+or no version (C<no>).  The option C<build> is mostly useful
+in C<configure> scripts of larger projects that bundle both C<isl>
+and C<piplib>.

+
+=head1 Integer Set Library
+
+=head2 Initialization
+
+All manipulations of integer sets and relations occur within
+the context of an C<isl_ctx>.
+A given C<isl_ctx> can only be used within a single thread.
+All arguments of a function are required to have been allocated
+within the same context.
+There are currently no functions available for moving an object
+from one C<isl_ctx> to another C<isl_ctx>.  This means that
+there is currently no way of safely moving an object from one
+thread to another, unless the whole C<isl_ctx> is moved.
+
+An C<isl_ctx> can be allocated using C<isl_ctx_alloc> and
+freed using C<isl_ctx_free>.
+All objects allocated within an C<isl_ctx> should be freed
+before the C<isl_ctx> itself is freed.
+
+	isl_ctx *isl_ctx_alloc();
+	void isl_ctx_free(isl_ctx *ctx);
+
+=head2 Integers
+
+All operations on integers, mainly the coefficients
+of the constraints describing the sets and relations,
+are performed in exact integer arithmetic using C<GMP>.
+However, to allow future versions of C<isl> to optionally
+support fixed integer arithmetic, all calls to C<GMP>
+are wrapped inside C<isl> specific macros.
+The basic type is C<isl_int> and the operations below
+are available on this type.
+The meanings of these operations are essentially the same
+as their C<GMP> C<mpz_> counterparts.
+As always with C<GMP> types, C<isl_int>s need to be
+initialized with C<isl_int_init> before they can be used
+and they need to be released with C<isl_int_clear>
+after the last use.
+The user should not assume that an C<isl_int> is represented
+as a C<mpz_t>, but should instead explicitly convert between
+C<mpz_t>s and C<isl_int>s using C<isl_int_set_gmp> and
+C<isl_int_get_gmp> whenever a C<mpz_t> is required.

+=head2 Sets and Relations
+
+C<isl> uses six types of objects for representing sets and relations,
+C<isl_basic_set>, C<isl_basic_map>, C<isl_set>, C<isl_map>,
+C<isl_union_set> and C<isl_union_map>.
+C<isl_basic_set> and C<isl_basic_map> represent sets and relations that
+can be described as a conjunction of affine constraints, while
+C<isl_set> and C<isl_map> represent unions of
+C<isl_basic_set>s and C<isl_basic_map>s, respectively.
+However, all C<isl_basic_set>s or C<isl_basic_map>s in the union need
+to live in the same space.  C<isl_union_set>s and C<isl_union_map>s
+represent unions of C<isl_set>s or C<isl_map>s in I<different> spaces,
+where spaces are considered different if they have a different number
+of dimensions and/or different names (see L<"Spaces">).
+The difference between sets and relations (maps) is that sets have
+one set of variables, while relations have two sets of variables,
+input variables and output variables.
+
+=head2 Memory Management
+
+Since a high-level operation on sets and/or relations usually involves
+several substeps and since the user is usually not interested in
+the intermediate results, most functions that return a new object
+will also release all the objects passed as arguments.
+If the user still wants to use one or more of these arguments
+after the function call, she should pass along a copy of the
+object rather than the object itself.
+The user is then responsible for making sure that the original
+object gets used somewhere else or is explicitly freed.
+
+The arguments and return values of all documented functions are
+annotated to make clear which arguments are released and which
+arguments are preserved.  In particular, the following annotations
+are used
+
+=over
+
+=item C<__isl_give>
+
+C<__isl_give> means that a new object is returned.
+The user should make sure that the returned pointer is
+used exactly once as a value for an C<__isl_take> argument.
+In between, it can be used as a value for as many
+C<__isl_keep> arguments as the user likes.
+There is one exception, and that is the case where the
+pointer returned is C<NULL>.  Is this case, the user
+is free to use it as an C<__isl_take> argument or not.
+
+=item C<__isl_take>
+
+C<__isl_take> means that the object the argument points to
+is taken over by the function and may no longer be used
+by the user as an argument to any other function.
+The pointer value must be one returned by a function
+returning an C<__isl_give> pointer.
+If the user passes in a C<NULL> value, then this will
+be treated as an error in the sense that the function will
+not perform its usual operation.  However, it will still
+make sure that all the other C<__isl_take> arguments
+are released.
+
+=item C<__isl_keep>
+
+C<__isl_keep> means that the function will only use the object
+temporarily.  After the function has finished, the user
+can still use it as an argument to other functions.
+A C<NULL> value will be treated in the same way as
+a C<NULL> value for an C<__isl_take> argument.
+
+=back
+
+=head2 Error Handling
+
+C<isl> supports different ways to react in case a runtime error is triggered.
+Runtime errors arise, e.g., if a function such as C<isl_map_intersect> is called
+with two maps that have incompatible spaces. There are three possible ways
+to react on error: to warn, to continue or to abort.
+
+The default behavior is to warn. In this mode, C<isl> prints a warning, stores
+the last error in the corresponding C<isl_ctx> and the function in which the
+error was triggered returns C<NULL>. An error does not corrupt internal state,
+such that isl can continue to be used. C<isl> also provides functions to
+read the last error and to reset the memory that stores the last error. The
+last error is only stored for information purposes. Its presence does not
+change the behavior of C<isl>. Hence, resetting an error is not required to
+continue to use isl, but only to observe new errors.
+
+	#include <isl/ctx.h>
+	enum isl_error isl_ctx_last_error(isl_ctx *ctx);
+	void isl_ctx_reset_error(isl_ctx *ctx);
+
+Another option is to continue on error. This is similar to warn on error mode,
+except that C<isl> does not print any warning. This allows a program to
+implement its own error reporting.
+
+The last option is to directly abort the execution of the program from within
+the isl library. This makes it obviously impossible to recover from an error,
+but it allows to directly spot the error location. By aborting on error,
+debuggers break at the location the error occurred and can provide a stack
+trace. Other tools that automatically provide stack traces on abort or that do
+not want to continue execution after an error was triggered may also prefer to
+abort on error.
+
+The on error behavior of isl can be specified by calling
+C<isl_options_set_on_error> or by setting the command line option
+C<--isl-on-error>. Valid arguments for the function call are
+C<ISL_ON_ERROR_WARN>, C<ISL_ON_ERROR_CONTINUE> and C<ISL_ON_ERROR_ABORT>. The
+choices for the command line option are C<warn>, C<continue> and C<abort>.
+It is also possible to query the current error mode.
+
+	#include <isl/options.h>
+	int isl_options_set_on_error(isl_ctx *ctx, int val);
+	int isl_options_get_on_error(isl_ctx *ctx);
+
+=head2 Identifiers
+
+Identifiers are used to identify both individual dimensions
+and tuples of dimensions.  They consist of an optional name and an optional
+user pointer.  The name and the user pointer cannot both be C<NULL>, however.
+Identifiers with the same name but different pointer values
+are considered to be distinct.
+Similarly, identifiers with different names but the same pointer value
+are also considered to be distinct.
+Equal identifiers are represented using the same object.
+Pairs of identifiers can therefore be tested for equality using the
+C<==> operator.
+Identifiers can be constructed, copied, freed, inspected and printed
+using the following functions.
+
+	#include <isl/id.h>
+	__isl_give isl_id *isl_id_alloc(isl_ctx *ctx,
+		__isl_keep const char *name, void *user);
+	__isl_give isl_id *isl_id_set_free_user(
+		__isl_take isl_id *id,
+		__isl_give void (*free_user)(void *user));
+	__isl_give isl_id *isl_id_copy(isl_id *id);
+	void *isl_id_free(__isl_take isl_id *id);
+
+	isl_ctx *isl_id_get_ctx(__isl_keep isl_id *id);
+	void *isl_id_get_user(__isl_keep isl_id *id);
+	__isl_keep const char *isl_id_get_name(__isl_keep isl_id *id);
+
+	__isl_give isl_printer *isl_printer_print_id(
+		__isl_take isl_printer *p, __isl_keep isl_id *id);
+
+The callback set by C<isl_id_set_free_user> is called on the user
+pointer when the last reference to the C<isl_id> is freed.
+Note that C<isl_id_get_name> returns a pointer to some internal
+data structure, so the result can only be used while the
+corresponding C<isl_id> is alive.
+
+=head2 Spaces
+
+Whenever a new set, relation or similiar object is created from scratch,
+the space in which it lives needs to be specified using an C<isl_space>.
+Each space involves zero or more parameters and zero, one or two
+tuples of set or input/output dimensions.  The parameters and dimensions
+are identified by an C<isl_dim_type> and a position.
+The type C<isl_dim_param> refers to parameters,
+the type C<isl_dim_set> refers to set dimensions (for spaces
+with a single tuple of dimensions) and the types C<isl_dim_in>
+and C<isl_dim_out> refer to input and output dimensions
+(for spaces with two tuples of dimensions).
+Local spaces (see L</"Local Spaces">) also contain dimensions
+of type C<isl_dim_div>.
+Note that parameters are only identified by their position within
+a given object.  Across different objects, parameters are (usually)
+identified by their names or identifiers.  Only unnamed parameters
+are identified by their positions across objects.  The use of unnamed
+parameters is discouraged.
+
+	#include <isl/space.h>
+	__isl_give isl_space *isl_space_alloc(isl_ctx *ctx,
+		unsigned nparam, unsigned n_in, unsigned n_out);
+	__isl_give isl_space *isl_space_params_alloc(isl_ctx *ctx,
+		unsigned nparam);
+	__isl_give isl_space *isl_space_set_alloc(isl_ctx *ctx,
+		unsigned nparam, unsigned dim);
+	__isl_give isl_space *isl_space_copy(__isl_keep isl_space *space);
+	void *isl_space_free(__isl_take isl_space *space);
+	unsigned isl_space_dim(__isl_keep isl_space *space,
+		enum isl_dim_type type);
+
+The space used for creating a parameter domain
+needs to be created using C<isl_space_params_alloc>.
+For other sets, the space
+needs to be created using C<isl_space_set_alloc>, while
+for a relation, the space
+needs to be created using C<isl_space_alloc>.
+C<isl_space_dim> can be used
+to find out the number of dimensions of each type in
+a space, where type may be
+C<isl_dim_param>, C<isl_dim_in> (only for relations),
+C<isl_dim_out> (only for relations), C<isl_dim_set>
+(only for sets) or C<isl_dim_all>.
+
+To check whether a given space is that of a set or a map
+or whether it is a parameter space, use these functions:
+
+	#include <isl/space.h>
+	int isl_space_is_params(__isl_keep isl_space *space);
+	int isl_space_is_set(__isl_keep isl_space *space);
+	int isl_space_is_map(__isl_keep isl_space *space);
+
+Spaces can be compared using the following functions:
+
+	#include <isl/space.h>
+	int isl_space_is_equal(__isl_keep isl_space *space1,
+		__isl_keep isl_space *space2);
+	int isl_space_is_domain(__isl_keep isl_space *space1,
+		__isl_keep isl_space *space2);
+	int isl_space_is_range(__isl_keep isl_space *space1,
+		__isl_keep isl_space *space2);
+
+C<isl_space_is_domain> checks whether the first argument is equal
+to the domain of the second argument.  This requires in particular that
+the first argument is a set space and that the second argument
+is a map space.
+
+It is often useful to create objects that live in the
+same space as some other object.  This can be accomplished
+by creating the new objects
+(see L<Creating New Sets and Relations> or
+L<Creating New (Piecewise) Quasipolynomials>) based on the space
+of the original object.

+
+The identifiers or names of the individual dimensions may be set or read off
+using the following functions.
+
+	#include <isl/space.h>
+	__isl_give isl_space *isl_space_set_dim_id(
+		__isl_take isl_space *space,
+		enum isl_dim_type type, unsigned pos,

+	int isl_space_has_dim_name(__isl_keep isl_space *space,
+		enum isl_dim_type type, unsigned pos);
+	__isl_keep const char *isl_space_get_dim_name(
+		__isl_keep isl_space *space,
+		enum isl_dim_type type, unsigned pos);
+
+Note that C<isl_space_get_name> returns a pointer to some internal
+data structure, so the result can only be used while the
+corresponding C<isl_space> is alive.
+Also note that every function that operates on two sets or relations
+requires that both arguments have the same parameters.  This also
+means that if one of the arguments has named parameters, then the
+other needs to have named parameters too and the names need to match.
+Pairs of C<isl_set>, C<isl_map>, C<isl_union_set> and/or C<isl_union_map>
+arguments may have different parameters (as long as they are named),
+in which case the result will have as parameters the union of the parameters of
+the arguments.
+
+Given the identifier or name of a dimension (typically a parameter),
+its position can be obtained from the following function.
+
+	#include <isl/space.h>
+	int isl_space_find_dim_by_id(__isl_keep isl_space *space,
+		enum isl_dim_type type, __isl_keep isl_id *id);
+	int isl_space_find_dim_by_name(__isl_keep isl_space *space,
+		enum isl_dim_type type, const char *name);
+
+The identifiers or names of entire spaces may be set or read off
+using the following functions.
+
+	#include <isl/space.h>
+	__isl_give isl_space *isl_space_set_tuple_id(
+		__isl_take isl_space *space,
+		enum isl_dim_type type, __isl_take isl_id *id);
+	__isl_give isl_space *isl_space_reset_tuple_id(
+		__isl_take isl_space *space, enum isl_dim_type type);
+	int isl_space_has_tuple_id(__isl_keep isl_space *space,
+		enum isl_dim_type type);
+	__isl_give isl_id *isl_space_get_tuple_id(
+		__isl_keep isl_space *space, enum isl_dim_type type);
+	__isl_give isl_space *isl_space_set_tuple_name(
+		__isl_take isl_space *space,
+		enum isl_dim_type type, const char *s);
+	int isl_space_has_tuple_name(__isl_keep isl_space *space,
+		enum isl_dim_type type);
+	const char *isl_space_get_tuple_name(__isl_keep isl_space *space,
+		enum isl_dim_type type);
+
+The C<type> argument needs to be one of C<isl_dim_in>, C<isl_dim_out>
+or C<isl_dim_set>.  As with C<isl_space_get_name>,
+the C<isl_space_get_tuple_name> function returns a pointer to some internal
+data structure.
+Binary operations require the corresponding spaces of their arguments
+to have the same name.
+
+Spaces can be nested.  In particular, the domain of a set or
+the domain or range of a relation can be a nested relation.
+The following functions can be used to construct and deconstruct
+such nested spaces.
+
+	#include <isl/space.h>
+	int isl_space_is_wrapping(__isl_keep isl_space *space);
+	__isl_give isl_space *isl_space_wrap(__isl_take isl_space *space);
+	__isl_give isl_space *isl_space_unwrap(__isl_take isl_space *space);
+
+The input to C<isl_space_is_wrapping> and C<isl_space_unwrap> should
+be the space of a set, while that of
+C<isl_space_wrap> should be the space of a relation.
+Conversely, the output of C<isl_space_unwrap> is the space
+of a relation, while that of C<isl_space_wrap> is the space of a set.
+
+Spaces can be created from other spaces
+using the following functions.
+
+	__isl_give isl_space *isl_space_domain(__isl_take isl_space *space);
+	__isl_give isl_space *isl_space_from_domain(__isl_take isl_space *space);
+	__isl_give isl_space *isl_space_range(__isl_take isl_space *space);

+	__isl_give isl_space *isl_space_zip(__isl_take isl_space *space);
+	__isl_give isl_space *isl_space_curry(
+		__isl_take isl_space *space);
+	__isl_give isl_space *isl_space_uncurry(
+		__isl_take isl_space *space);
+
+Note that if dimensions are added or removed from a space, then
+the name and the internal structure are lost.
+
+=head2 Local Spaces
+
+A local space is essentially a space with
+zero or more existentially quantified variables.
+The local space of a (constraint of a) basic set or relation can be obtained
+using the following functions.
+
+	#include <isl/constraint.h>
+	__isl_give isl_local_space *isl_constraint_get_local_space(
+		__isl_keep isl_constraint *constraint);
+
+	#include <isl/set.h>
+	__isl_give isl_local_space *isl_basic_set_get_local_space(
+		__isl_keep isl_basic_set *bset);
+
+	#include <isl/map.h>
+	__isl_give isl_local_space *isl_basic_map_get_local_space(
+		__isl_keep isl_basic_map *bmap);
+
+A new local space can be created from a space using
+
+	#include <isl/local_space.h>
+	__isl_give isl_local_space *isl_local_space_from_space(
+		__isl_take isl_space *space);
+
+They can be inspected, modified, copied and freed using the following functions.
+
+	#include <isl/local_space.h>
+	isl_ctx *isl_local_space_get_ctx(
+		__isl_keep isl_local_space *ls);
+	int isl_local_space_is_set(__isl_keep isl_local_space *ls);
+	int isl_local_space_dim(__isl_keep isl_local_space *ls,
+		enum isl_dim_type type);
+	int isl_local_space_has_dim_id(
+		__isl_keep isl_local_space *ls,
+		enum isl_dim_type type, unsigned pos);
+	__isl_give isl_id *isl_local_space_get_dim_id(

+		enum isl_dim_type type, unsigned pos);
+	int isl_local_space_has_dim_name(

+	__isl_give isl_local_space *isl_local_space_set_dim_name(
+		__isl_take isl_local_space *ls,
+		enum isl_dim_type type, unsigned pos, const char *s);
+	__isl_give isl_local_space *isl_local_space_set_dim_id(

+	__isl_give isl_local_space *isl_local_space_copy(
+		__isl_keep isl_local_space *ls);
+	void *isl_local_space_free(__isl_take isl_local_space *ls);
+
+Two local spaces can be compared using
+
+	int isl_local_space_is_equal(__isl_keep isl_local_space *ls1,
+		__isl_keep isl_local_space *ls2);
+
+Local spaces can be created from other local spaces
+using the following functions.
+
+	__isl_give isl_local_space *isl_local_space_domain(
+		__isl_take isl_local_space *ls);
+	__isl_give isl_local_space *isl_local_space_range(

+		__isl_take isl_local_space *ls,
+		enum isl_dim_type type, unsigned first, unsigned n);
+
+=head2 Input and Output
+
+C<isl> supports its own input/output format, which is similar
+to the C<Omega> format, but also supports the C<PolyLib> format
+in some cases.
+
+=head3 C<isl> format
+
+The C<isl> format is similar to that of C<Omega>, but has a different
+syntax for describing the parameters and allows for the definition
+of an existentially quantified variable as the integer division
+of an affine expression.
+For example, the set of integers C<i> between C<0> and C<n>
+such that C<i % 10 <= 6> can be described as
+
+	[n] -> { [i] : exists (a = [i/10] : 0 <= i and i <= n and
+				i - 10 a <= 6) }
+
+A set or relation can have several disjuncts, separated
+by the keyword C<or>.  Each disjunct is either a conjunction
+of constraints or a projection (C<exists>) of a conjunction
+of constraints.  The constraints are separated by the keyword
+C<and>.
+
+=head3 C<PolyLib> format
+
+If the represented set is a union, then the first line
+contains a single number representing the number of disjuncts.
+Otherwise, a line containing the number C<1> is optional.
+
+Each disjunct is represented by a matrix of constraints.
+The first line contains two numbers representing
+the number of rows and columns,
+where the number of rows is equal to the number of constraints
+and the number of columns is equal to two plus the number of variables.
+The following lines contain the actual rows of the constraint matrix.
+In each row, the first column indicates whether the constraint
+is an equality (C<0>) or inequality (C<1>).  The final column
+corresponds to the constant term.
+
+If the set is parametric, then the coefficients of the parameters
+appear in the last columns before the constant column.
+The coefficients of any existentially quantified variables appear
+between those of the set variables and those of the parameters.
+
+=head3 Extended C<PolyLib> format
+
+The extended C<PolyLib> format is nearly identical to the
+C<PolyLib> format.  The only difference is that the line
+containing the number of rows and columns of a constraint matrix
+also contains four additional numbers:
+the number of output dimensions, the number of input dimensions,
+the number of local dimensions (i.e., the number of existentially
+quantified variables) and the number of parameters.
+For sets, the number of ``output'' dimensions is equal
+to the number of set dimensions, while the number of ``input''
+dimensions is zero.

+	__isl_give isl_union_map *isl_union_map_from_map(

+
+The inverse conversions below can only be used if the input
+union set or relation is known to contain elements in exactly one
+space.
+

+
+Other sets and relations can be constructed by starting
+from a universe set or relation, adding equality and/or
+inequality constraints and then projecting out the
+existentially quantified variables, if any.
+Constraints can be constructed, manipulated and
+added to (or removed from) (basic) sets and relations
+using the following functions.
+
+	#include <isl/constraint.h>
+	__isl_give isl_constraint *isl_equality_alloc(
+		__isl_take isl_local_space *ls);
+	__isl_give isl_constraint *isl_inequality_alloc(

+	__isl_give isl_constraint *isl_constraint_set_constant(

+	__isl_give isl_constraint *isl_constraint_set_coefficient(

+	__isl_give isl_constraint *isl_constraint_set_coefficient_si(
+		__isl_take isl_constraint *constraint,
+		enum isl_dim_type type, int pos, int v);
+	__isl_give isl_basic_map *isl_basic_map_add_constraint(

+		__isl_take isl_constraint *constraint);
+	__isl_give isl_basic_set *isl_basic_set_add_constraint(

+		__isl_take isl_constraint *constraint);
+	__isl_give isl_map *isl_map_add_constraint(

+		__isl_take isl_constraint *constraint);
+	__isl_give isl_set *isl_set_add_constraint(

+	__isl_give isl_basic_set *isl_basic_set_drop_constraint(
+		__isl_take isl_basic_set *bset,
+		__isl_take isl_constraint *constraint);
+
+For example, to create a set containing the even integers
+between 10 and 42, you would use the following code.
+
+	isl_space *space;
+	isl_local_space *ls;
+	isl_constraint *c;
+	isl_basic_set *bset;
+
+	space = isl_space_set_alloc(ctx, 0, 2);
+	bset = isl_basic_set_universe(isl_space_copy(space));
+	ls = isl_local_space_from_space(space);
+
+	c = isl_equality_alloc(isl_local_space_copy(ls));
+	c = isl_constraint_set_coefficient_si(c, isl_dim_set, 0, -1);
+	c = isl_constraint_set_coefficient_si(c, isl_dim_set, 1, 2);
+	bset = isl_basic_set_add_constraint(bset, c);
+
+	c = isl_inequality_alloc(isl_local_space_copy(ls));
+	c = isl_constraint_set_constant_si(c, -10);
+	c = isl_constraint_set_coefficient_si(c, isl_dim_set, 0, 1);
+	bset = isl_basic_set_add_constraint(bset, c);
+
+	c = isl_inequality_alloc(ls);
+	c = isl_constraint_set_constant_si(c, 42);
+	c = isl_constraint_set_coefficient_si(c, isl_dim_set, 0, -1);
+	bset = isl_basic_set_add_constraint(bset, c);
+
+	bset = isl_basic_set_project_out(bset, isl_dim_set, 1, 1);
+
+Or, alternatively,
+
+	isl_basic_set *bset;
+	bset = isl_basic_set_read_from_str(ctx,
+		"{[i] : exists (a : i = 2a and i >= 10 and i <= 42)}");
+
+A basic set or relation can also be constructed from two matrices
+describing the equalities and the inequalities.
+
+	__isl_give isl_basic_set *isl_basic_set_from_constraint_matrices(
+		__isl_take isl_space *space,
+		__isl_take isl_mat *eq, __isl_take isl_mat *ineq,
+		enum isl_dim_type c1,
+		enum isl_dim_type c2, enum isl_dim_type c3,
+		enum isl_dim_type c4);
+	__isl_give isl_basic_map *isl_basic_map_from_constraint_matrices(
+		__isl_take isl_space *space,
+		__isl_take isl_mat *eq, __isl_take isl_mat *ineq,
+		enum isl_dim_type c1,
+		enum isl_dim_type c2, enum isl_dim_type c3,
+		enum isl_dim_type c4, enum isl_dim_type c5);
+
+The C<isl_dim_type> arguments indicate the order in which
+different kinds of variables appear in the input matrices
+and should be a permutation of C<isl_dim_cst>, C<isl_dim_param>,
+C<isl_dim_set> and C<isl_dim_div> for sets and
+of C<isl_dim_cst>, C<isl_dim_param>,
+C<isl_dim_in>, C<isl_dim_out> and C<isl_dim_div> for relations.
+
+A (basic or union) set or relation can also be constructed from a
+(union) (piecewise) (multiple) affine expression
+or a list of affine expressions
+(See L<"Piecewise Quasi Affine Expressions"> and
+L<"Piecewise Multiple Quasi Affine Expressions">).
+
+	__isl_give isl_basic_map *isl_basic_map_from_aff(
+		__isl_take isl_aff *aff);
+	__isl_give isl_map *isl_map_from_aff(
+		__isl_take isl_aff *aff);
+	__isl_give isl_set *isl_set_from_pw_aff(
+		__isl_take isl_pw_aff *pwaff);
+	__isl_give isl_map *isl_map_from_pw_aff(
+		__isl_take isl_pw_aff *pwaff);
+	__isl_give isl_basic_map *isl_basic_map_from_aff_list(
+		__isl_take isl_space *domain_space,
+		__isl_take isl_aff_list *list);
+	__isl_give isl_basic_map *isl_basic_map_from_multi_aff(
+		__isl_take isl_multi_aff *maff)
+	__isl_give isl_map *isl_map_from_multi_aff(
+		__isl_take isl_multi_aff *maff)
+	__isl_give isl_set *isl_set_from_pw_multi_aff(
+		__isl_take isl_pw_multi_aff *pma);
+	__isl_give isl_map *isl_map_from_pw_multi_aff(
+		__isl_take isl_pw_multi_aff *pma);
+	__isl_give isl_union_map *
+	isl_union_map_from_union_pw_multi_aff(
+		__isl_take isl_union_pw_multi_aff *upma);
+
+The C<domain_dim> argument describes the domain of the resulting
+basic relation.  It is required because the C<list> may consist
+of zero affine expressions.
+
+=head2 Inspecting Sets and Relations
+
+Usually, the user should not have to care about the actual constraints
+of the sets and maps, but should instead apply the abstract operations
+explained in the following sections.
+Occasionally, however, it may be required to inspect the individual
+coefficients of the constraints.  This section explains how to do so.
+In these cases, it may also be useful to have C<isl> compute
+an explicit representation of the existentially quantified variables.
+
+	__isl_give isl_set *isl_set_compute_divs(
+		__isl_take isl_set *set);
+	__isl_give isl_map *isl_map_compute_divs(
+		__isl_take isl_map *map);
+	__isl_give isl_union_set *isl_union_set_compute_divs(
+		__isl_take isl_union_set *uset);
+	__isl_give isl_union_map *isl_union_map_compute_divs(
+		__isl_take isl_union_map *umap);
+
+This explicit representation defines the existentially quantified
+variables as integer divisions of the other variables, possibly
+including earlier existentially quantified variables.
+An explicitly represented existentially quantified variable therefore
+has a unique value when the values of the other variables are known.
+If, furthermore, the same existentials, i.e., existentials
+with the same explicit representations, should appear in the
+same order in each of the disjuncts of a set or map, then the user should call
+either of the following functions.
+
+	__isl_give isl_set *isl_set_align_divs(
+		__isl_take isl_set *set);
+	__isl_give isl_map *isl_map_align_divs(
+		__isl_take isl_map *map);
+
+Alternatively, the existentially quantified variables can be removed
+using the following functions, which compute an overapproximation.
+
+	__isl_give isl_basic_set *isl_basic_set_remove_divs(
+		__isl_take isl_basic_set *bset);
+	__isl_give isl_basic_map *isl_basic_map_remove_divs(
+		__isl_take isl_basic_map *bmap);
+	__isl_give isl_set *isl_set_remove_divs(
+		__isl_take isl_set *set);
+	__isl_give isl_map *isl_map_remove_divs(
+		__isl_take isl_map *map);
+
+It is also possible to only remove those divs that are defined
+in terms of a given range of dimensions or only those for which
+no explicit representation is known.
+
+	__isl_give isl_basic_set *
+	isl_basic_set_remove_divs_involving_dims(
+		__isl_take isl_basic_set *bset,
+		enum isl_dim_type type,
+		unsigned first, unsigned n);
+	__isl_give isl_basic_map *
+	isl_basic_map_remove_divs_involving_dims(
+		__isl_take isl_basic_map *bmap,
+		enum isl_dim_type type,
+		unsigned first, unsigned n);
+	__isl_give isl_set *isl_set_remove_divs_involving_dims(
+		__isl_take isl_set *set, enum isl_dim_type type,
+		unsigned first, unsigned n);
+	__isl_give isl_map *isl_map_remove_divs_involving_dims(
+		__isl_take isl_map *map, enum isl_dim_type type,
+		unsigned first, unsigned n);
+
+	__isl_give isl_basic_set *
+	isl_basic_set_remove_unknown_divs(
+		__isl_take isl_basic_set *bset);
+	__isl_give isl_set *isl_set_remove_unknown_divs(
+		__isl_take isl_set *set);
+	__isl_give isl_map *isl_map_remove_unknown_divs(
+		__isl_take isl_map *map);
+
+To iterate over all the sets or maps in a union set or map, use
+
+	int isl_union_set_foreach_set(__isl_keep isl_union_set *uset,
+		int (*fn)(__isl_take isl_set *set, void *user),
+		void *user);
+	int isl_union_map_foreach_map(__isl_keep isl_union_map *umap,
+		int (*fn)(__isl_take isl_map *map, void *user),
+		void *user);
+
+The number of sets or maps in a union set or map can be obtained
+from
+
+	int isl_union_set_n_set(__isl_keep isl_union_set *uset);
+	int isl_union_map_n_map(__isl_keep isl_union_map *umap);
+
+To extract the set or map in a given space from a union, use
+
+	__isl_give isl_set *isl_union_set_extract_set(
+		__isl_keep isl_union_set *uset,
+		__isl_take isl_space *space);
+	__isl_give isl_map *isl_union_map_extract_map(
+		__isl_keep isl_union_map *umap,
+		__isl_take isl_space *space);
+
+To iterate over all the basic sets or maps in a set or map, use
+
+	int isl_set_foreach_basic_set(__isl_keep isl_set *set,
+		int (*fn)(__isl_take isl_basic_set *bset, void *user),
+		void *user);
+	int isl_map_foreach_basic_map(__isl_keep isl_map *map,
+		int (*fn)(__isl_take isl_basic_map *bmap, void *user),
+		void *user);
+
+The callback function C<fn> should return 0 if successful and
+-1 if an error occurs.  In the latter case, or if any other error
+occurs, the above functions will return -1.
+
+It should be noted that C<isl> does not guarantee that
+the basic sets or maps passed to C<fn> are disjoint.
+If this is required, then the user should call one of
+the following functions first.
+
+	__isl_give isl_set *isl_set_make_disjoint(
+		__isl_take isl_set *set);
+	__isl_give isl_map *isl_map_make_disjoint(
+		__isl_take isl_map *map);
+
+The number of basic sets in a set can be obtained
+from
+
+	int isl_set_n_basic_set(__isl_keep isl_set *set);
+
+To iterate over the constraints of a basic set or map, use
+
+	#include <isl/constraint.h>
+
+	int isl_basic_set_n_constraint(
+		__isl_keep isl_basic_set *bset);
+	int isl_basic_set_foreach_constraint(
+		__isl_keep isl_basic_set *bset,
+		int (*fn)(__isl_take isl_constraint *c, void *user),
+		void *user);
+	int isl_basic_map_foreach_constraint(
+		__isl_keep isl_basic_map *bmap,
+		int (*fn)(__isl_take isl_constraint *c, void *user),
+		void *user);
+	void *isl_constraint_free(__isl_take isl_constraint *c);
+
+Again, the callback function C<fn> should return 0 if successful and
+-1 if an error occurs.  In the latter case, or if any other error
+occurs, the above functions will return -1.
+The constraint C<c> represents either an equality or an inequality.
+Use the following function to find out whether a constraint
+represents an equality.  If not, it represents an inequality.
+
+	int isl_constraint_is_equality(
+		__isl_keep isl_constraint *constraint);
+
+The coefficients of the constraints can be inspected using
+the following functions.
+
+	int isl_constraint_is_lower_bound(
+		__isl_keep isl_constraint *constraint,
+		enum isl_dim_type type, unsigned pos);
+	int isl_constraint_is_upper_bound(
+		__isl_keep isl_constraint *constraint,
+		enum isl_dim_type type, unsigned pos);
+	void isl_constraint_get_constant(
+		__isl_keep isl_constraint *constraint, isl_int *v);
+	void isl_constraint_get_coefficient(
+		__isl_keep isl_constraint *constraint,
+		enum isl_dim_type type, int pos, isl_int *v);
+	int isl_constraint_involves_dims(
+		__isl_keep isl_constraint *constraint,
+		enum isl_dim_type type, unsigned first, unsigned n);
+
+The explicit representations of the existentially quantified
+variables can be inspected using the following function.
+Note that the user is only allowed to use this function
+if the inspected set or map is the result of a call
+to C<isl_set_compute_divs> or C<isl_map_compute_divs>.
+The existentially quantified variable is equal to the floor
+of the returned affine expression.  The affine expression
+itself can be inspected using the functions in
+L<"Piecewise Quasi Affine Expressions">.
+
+	__isl_give isl_aff *isl_constraint_get_div(
+		__isl_keep isl_constraint *constraint, int pos);
+
+To obtain the constraints of a basic set or map in matrix
+form, use the following functions.
+

+The C<isl_dim_type> arguments dictate the order in which

+
+The number of parameters, input, output or set dimensions can
+be obtained using the following functions.
+
+	unsigned isl_basic_set_dim(__isl_keep isl_basic_set *bset,

+	unsigned isl_map_dim(__isl_keep isl_map *map,
+		enum isl_dim_type type);
+
+To check whether the description of a set or relation depends
+on one or more given dimensions, it is not necessary to iterate over all
+constraints.  Instead the following functions can be used.
+
+	int isl_basic_set_involves_dims(

+		enum isl_dim_type type, unsigned pos);
+	int isl_set_dim_has_any_upper_bound(__isl_keep isl_set *set,
+		enum isl_dim_type type, unsigned pos);
+
+Note that these functions return true even if there is a bound on
+the dimension on only some of the basic sets of C<set>.
+To check if they have a bound for all of the basic sets in C<set>,
+use the following functions instead.
+
+	int isl_set_dim_has_lower_bound(__isl_keep isl_set *set,
+		enum isl_dim_type type, unsigned pos);
+	int isl_set_dim_has_upper_bound(__isl_keep isl_set *set,

+

+In other words, C<ma2> is plugged

+
+	__isl_give isl_set *isl_multi_aff_lex_le_set(

+=head2 Points
+
+Points are elements of a set.  They can be used to construct
+simple sets (boxes) or they can be used to represent the
+individual elements of a set.
+The zero point (the origin) can be created using
+
+	__isl_give isl_point *isl_point_zero(__isl_take isl_space *space);
+
+The coordinates of a point can be inspected, set and changed
+using
+
+	int isl_point_get_coordinate(__isl_keep isl_point *pnt,
+		enum isl_dim_type type, int pos, isl_int *v);
+	__isl_give isl_point *isl_point_set_coordinate(
+		__isl_take isl_point *pnt,
+		enum isl_dim_type type, int pos, isl_int v);
+
+	__isl_give isl_point *isl_point_add_ui(
+		__isl_take isl_point *pnt,
+		enum isl_dim_type type, int pos, unsigned val);
+	__isl_give isl_point *isl_point_sub_ui(
+		__isl_take isl_point *pnt,
+		enum isl_dim_type type, int pos, unsigned val);
+
+Other properties can be obtained using
+
+	isl_ctx *isl_point_get_ctx(__isl_keep isl_point *pnt);
+
+Points can be copied or freed using
+
+	__isl_give isl_point *isl_point_copy(
+		__isl_keep isl_point *pnt);
+	void isl_point_free(__isl_take isl_point *pnt);
+
+A singleton set can be created from a point using
+
+	__isl_give isl_basic_set *isl_basic_set_from_point(
+		__isl_take isl_point *pnt);
+	__isl_give isl_set *isl_set_from_point(
+		__isl_take isl_point *pnt);
+
+and a box can be created from two opposite extremal points using
+
+	__isl_give isl_basic_set *isl_basic_set_box_from_points(
+		__isl_take isl_point *pnt1,
+		__isl_take isl_point *pnt2);
+	__isl_give isl_set *isl_set_box_from_points(
+		__isl_take isl_point *pnt1,
+		__isl_take isl_point *pnt2);
+
+All elements of a B<bounded> (union) set can be enumerated using
+the following functions.
+
+	int isl_set_foreach_point(__isl_keep isl_set *set,
+		int (*fn)(__isl_take isl_point *pnt, void *user),
+		void *user);
+	int isl_union_set_foreach_point(__isl_keep isl_union_set *uset,
+		int (*fn)(__isl_take isl_point *pnt, void *user),
+		void *user);
+
+The function C<fn> is called for each integer point in
+C<set> with as second argument the last argument of
+the C<isl_set_foreach_point> call.  The function C<fn>
+should return C<0> on success and C<-1> on failure.
+In the latter case, C<isl_set_foreach_point> will stop
+enumerating and return C<-1> as well.
+If the enumeration is performed successfully and to completion,
+then C<isl_set_foreach_point> returns C<0>.
+
+To obtain a single point of a (basic) set, use
+
+	__isl_give isl_point *isl_basic_set_sample_point(
+		__isl_take isl_basic_set *bset);
+	__isl_give isl_point *isl_set_sample_point(
+		__isl_take isl_set *set);
+
+If C<set> does not contain any (integer) points, then the
+resulting point will be ``void'', a property that can be
+tested using
+
+	int isl_point_is_void(__isl_keep isl_point *pnt);
+
+=head2 Piecewise Quasipolynomials
+
+A piecewise quasipolynomial is a particular kind of function that maps
+a parametric point to a rational value.
+More specifically, a quasipolynomial is a polynomial expression in greatest
+integer parts of affine expressions of parameters and variables.
+A piecewise quasipolynomial is a subdivision of a given parametric
+domain into disjoint cells with a quasipolynomial associated to
+each cell.  The value of the piecewise quasipolynomial at a given
+point is the value of the quasipolynomial associated to the cell
+that contains the point.  Outside of the union of cells,
+the value is assumed to be zero.
+For example, the piecewise quasipolynomial
+
+	[n] -> { [x] -> ((1 + n) - x) : x <= n and x >= 0 }
+
+maps C<x> to C<1 + n - x> for values of C<x> between C<0> and C<n>.
+A given piecewise quasipolynomial has a fixed domain dimension.
+Union piecewise quasipolynomials are used to contain piecewise quasipolynomials
+defined over different domains.
+Piecewise quasipolynomials are mainly used by the C<barvinok>
+library for representing the number of elements in a parametric set or map.
+For example, the piecewise quasipolynomial above represents
+the number of points in the map
+
+	[n] -> { [x] -> [y] : x,y >= 0 and 0 <= x + y <= n }
+
+=head3 Input and Output
+
+Piecewise quasipolynomials can be read from input using
+
+	__isl_give isl_union_pw_qpolynomial *
+	isl_union_pw_qpolynomial_read_from_str(
+		isl_ctx *ctx, const char *str);
+
+Quasipolynomials and piecewise quasipolynomials can be printed
+using the following functions.
+
+	__isl_give isl_printer *isl_printer_print_qpolynomial(
+		__isl_take isl_printer *p,
+		__isl_keep isl_qpolynomial *qp);
+
+	__isl_give isl_printer *isl_printer_print_pw_qpolynomial(

+
+	__isl_give isl_printer *isl_printer_print_union_pw_qpolynomial(
+		__isl_take isl_printer *p,
+		__isl_keep isl_union_pw_qpolynomial *upwqp);
+
+The output format of the printer
+needs to be set to either C<ISL_FORMAT_ISL> or C<ISL_FORMAT_C>.
+For C<isl_printer_print_union_pw_qpolynomial>, only C<ISL_FORMAT_ISL>
+is supported.
+In case of printing in C<ISL_FORMAT_C>, the user may want
+to set the names of all dimensions
+
+	__isl_give isl_qpolynomial *isl_qpolynomial_set_dim_name(
+		__isl_take isl_qpolynomial *qp,
+		enum isl_dim_type type, unsigned pos,
+		const char *s);
+	__isl_give isl_pw_qpolynomial *

+		__isl_take isl_pw_qpolynomial *pwqp,
+		enum isl_dim_type type, unsigned pos,

+
+=head3 Creating New (Piecewise) Quasipolynomials
+
+Some simple quasipolynomials can be created using the following functions.
+More complicated quasipolynomials can be created by applying
+operations such as addition and multiplication
+on the resulting quasipolynomials
+
+	__isl_give isl_qpolynomial *isl_qpolynomial_zero_on_domain(
+		__isl_take isl_space *domain);
+	__isl_give isl_qpolynomial *isl_qpolynomial_one_on_domain(
+		__isl_take isl_space *domain);
+	__isl_give isl_qpolynomial *isl_qpolynomial_infty_on_domain(
+		__isl_take isl_space *domain);
+	__isl_give isl_qpolynomial *isl_qpolynomial_neginfty_on_domain(
+		__isl_take isl_space *domain);
+	__isl_give isl_qpolynomial *isl_qpolynomial_nan_on_domain(
+		__isl_take isl_space *domain);
+	__isl_give isl_qpolynomial *isl_qpolynomial_rat_cst_on_domain(

+		__isl_take isl_space *domain,
+		enum isl_dim_type type, unsigned pos);
+	__isl_give isl_qpolynomial *isl_qpolynomial_from_aff(
+		__isl_take isl_aff *aff);
+
+Note that the space in which a quasipolynomial lives is a map space
+with a one-dimensional range.  The C<domain> argument in some of
+the functions above corresponds to the domain of this map space.
+
+The zero piecewise quasipolynomial or a piecewise quasipolynomial
+with a single cell can be created using the following functions.
+Multiple of these single cell piecewise quasipolynomials can
+be combined to create more complicated piecewise quasipolynomials.
+
+	__isl_give isl_pw_qpolynomial *isl_pw_qpolynomial_zero(

+		__isl_take isl_union_pw_qpolynomial *upwqp,
+		__isl_take isl_pw_qpolynomial *pwqp);
+
+Quasipolynomials can be copied and freed again using the following
+functions.
+
+	__isl_give isl_qpolynomial *isl_qpolynomial_copy(
+		__isl_keep isl_qpolynomial *qp);

+=head3 Inspecting (Piecewise) Quasipolynomials
+
+To iterate over all piecewise quasipolynomials in a union
+piecewise quasipolynomial, use the following function
+
+	int isl_union_pw_qpolynomial_foreach_pw_qpolynomial(
+		__isl_keep isl_union_pw_qpolynomial *upwqp,
+		int (*fn)(__isl_take isl_pw_qpolynomial *pwqp, void *user),
+		void *user);
+
+To extract the piecewise quasipolynomial in a given space from a union, use
+
+	__isl_give isl_pw_qpolynomial *
+	isl_union_pw_qpolynomial_extract_pw_qpolynomial(
+		__isl_keep isl_union_pw_qpolynomial *upwqp,
+		__isl_take isl_space *space);
+
+To iterate over the cells in a piecewise quasipolynomial,
+use either of the following two functions
+
+	int isl_pw_qpolynomial_foreach_piece(
+		__isl_keep isl_pw_qpolynomial *pwqp,
+		int (*fn)(__isl_take isl_set *set,
+			  __isl_take isl_qpolynomial *qp,
+			  void *user), void *user);
+	int isl_pw_qpolynomial_foreach_lifted_piece(
+		__isl_keep isl_pw_qpolynomial *pwqp,
+		int (*fn)(__isl_take isl_set *set,
+			  __isl_take isl_qpolynomial *qp,
+			  void *user), void *user);
+
+As usual, the function C<fn> should return C<0> on success
+and C<-1> on failure.  The difference between
+C<isl_pw_qpolynomial_foreach_piece> and
+C<isl_pw_qpolynomial_foreach_lifted_piece> is that
+C<isl_pw_qpolynomial_foreach_lifted_piece> will first
+compute unique representations for all existentially quantified
+variables and then turn these existentially quantified variables
+into extra set variables, adapting the associated quasipolynomial
+accordingly.  This means that the C<set> passed to C<fn>
+will not have any existentially quantified variables, but that
+the dimensions of the sets may be different for different
+invocations of C<fn>.
+
+To iterate over all terms in a quasipolynomial,
+use
+
+	int isl_qpolynomial_foreach_term(
+		__isl_keep isl_qpolynomial *qp,
+		int (*fn)(__isl_take isl_term *term,
+			  void *user), void *user);
+
+The terms themselves can be inspected and freed using
+these functions
+
+	unsigned isl_term_dim(__isl_keep isl_term *term,
+		enum isl_dim_type type);
+	void isl_term_get_num(__isl_keep isl_term *term,
+		isl_int *n);
+	void isl_term_get_den(__isl_keep isl_term *term,
+		isl_int *d);
+	int isl_term_get_exp(__isl_keep isl_term *term,
+		enum isl_dim_type type, unsigned pos);
+	__isl_give isl_aff *isl_term_get_div(
+		__isl_keep isl_term *term, unsigned pos);
+	void isl_term_free(__isl_take isl_term *term);
+
+Each term is a product of parameters, set variables and
+integer divisions.  The function C<isl_term_get_exp>
+returns the exponent of a given dimensions in the given term.
+The C<isl_int>s in the arguments of C<isl_term_get_num>
+and C<isl_term_get_den> need to have been initialized
+using C<isl_int_init> before calling these functions.
+
+=head3 Properties of (Piecewise) Quasipolynomials
+
+To check whether a quasipolynomial is actually a constant,
+use the following function.
+
+	int isl_qpolynomial_is_cst(__isl_keep isl_qpolynomial *qp,
+		isl_int *n, isl_int *d);
+
+If C<qp> is a constant and if C<n> and C<d> are not C<NULL>
+then the numerator and denominator of the constant
+are returned in C<*n> and C<*d>, respectively.
+
+To check whether two union piecewise quasipolynomials are
+obviously equal, use
+
+	int isl_union_pw_qpolynomial_plain_is_equal(

+
+=head2 Bounds on Piecewise Quasipolynomials and Piecewise Quasipolynomial Reductions
+
+A piecewise quasipolynomial reduction is a piecewise
+reduction (or fold) of quasipolynomials.
+In particular, the reduction can be maximum or a minimum.
+The objects are mainly used to represent the result of
+an upper or lower bound on a quasipolynomial over its domain,
+i.e., as the result of the following function.
+
+	__isl_give isl_pw_qpolynomial_fold *isl_pw_qpolynomial_bound(
+		__isl_take isl_pw_qpolynomial *pwqp,
+		enum isl_fold type, int *tight);
+
+	__isl_give isl_union_pw_qpolynomial_fold *isl_union_pw_qpolynomial_bound(
+		__isl_take isl_union_pw_qpolynomial *upwqp,
+		enum isl_fold type, int *tight);
+
+The C<type> argument may be either C<isl_fold_min> or C<isl_fold_max>.
+If C<tight> is not C<NULL>, then C<*tight> is set to C<1>
+is the returned bound is known be tight, i.e., for each value
+of the parameters there is at least
+one element in the domain that reaches the bound.
+If the domain of C<pwqp> is not wrapping, then the bound is computed
+over all elements in that domain and the result has a purely parametric
+domain.  If the domain of C<pwqp> is wrapping, then the bound is
+computed over the range of the wrapped relation.  The domain of the
+wrapped relation becomes the domain of the result.
+
+A (piecewise) quasipolynomial reduction can be copied or freed using the
+following functions.
+
+	__isl_give isl_qpolynomial_fold *isl_qpolynomial_fold_copy(

+output format of the printer
+needs to be set to either C<ISL_FORMAT_ISL> or C<ISL_FORMAT_C>.
+For C<isl_printer_print_union_pw_qpolynomial_fold>,
+output format of the printer
+needs to be set to C<ISL_FORMAT_ISL>.
+In case of printing in C<ISL_FORMAT_C>, the user may want

+
+This section collects functionality in C<isl> that has been specifically
+designed for use during polyhedral compilation.
+
+=head2 Dependence Analysis
+
+C<isl> contains specialized functionality for performing
+array dataflow analysis.  That is, given a I<sink> access relation
+and a collection of possible I<source> access relations,
+C<isl> can compute relations that describe
+for each iteration of the sink access, which iteration
+of which of the source access relations was the last
+to access the same data element before the given iteration
+of the sink access.
+The resulting dependence relations map source iterations
+to the corresponding sink iterations.
+To compute standard flow dependences, the sink should be
+a read, while the sources should be writes.
+If any of the source accesses are marked as being I<may>
+accesses, then there will be a dependence from the last
+I<must> access B<and> from any I<may> access that follows
+this last I<must> access.
+In particular, if I<all> sources are I<may> accesses,

+
+The function C<isl_access_info_compute_flow> performs the actual
+dependence analysis.  The other functions are used to construct
+the input for this function or to read off the output.
+
+The input is collected in an C<isl_access_info>, which can
+be created through a call to C<isl_access_info_alloc>.
+The arguments to this functions are the sink access relation
+C<sink>, a token C<sink_user> used to identify the sink
+access to the user, a callback function for specifying the
+relative order of source and sink accesses, and the number
+of source access relations that will be added.
+The callback function has type C<int (*)(void *first, void *second)>.
+The function is called with two user supplied tokens identifying
+either a source or the sink and it should return the shared nesting
+level and the relative order of the two accesses.
+In particular, let I<n> be the number of loops shared by
+the two accesses.  If C<first> precedes C<second> textually,
+then the function should return I<2 * n + 1>; otherwise,
+it should return I<2 * n>.
+The sources can be added to the C<isl_access_info> by performing
+(at most) C<max_source> calls to C<isl_access_info_add_source>.
+C<must> indicates whether the source is a I<must> access
+or a I<may> access.  Note that a multi-valued access relation
+should only be marked I<must> if every iteration in the domain
+of the relation accesses I<all> elements in its image.
+The C<source_user> token is again used to identify
+the source access.  The range of the source access relation
+C<source> should have the same dimension as the range
+of the sink access relation.
+The C<isl_access_info_free> function should usually not be
+called explicitly, because it is called implicitly by
+C<isl_access_info_compute_flow>.
+
+The result of the dependence analysis is collected in an
+C<isl_flow>.  There may be elements of
+the sink access for which no preceding source access could be
+found or for which all preceding sources are I<may> accesses.
+The relations containing these elements can be obtained through
+calls to C<isl_flow_get_no_source>, the first with C<must> set
+and the second with C<must> unset.
+In the case of standard flow dependence analysis,
+with the sink a read and the sources I<must> writes,
+the first relation corresponds to the reads from uninitialized
+array elements and the second relation is empty.
+The actual flow dependences can be extracted using
+C<isl_flow_foreach>.  This function will call the user-specified
+callback function C<fn> for each B<non-empty> dependence between
+a source and the sink.  The callback function is called
+with four arguments, the actual flow dependence relation
+mapping source iterations to sink iterations, a boolean that
+indicates whether it is a I<must> or I<may> dependence, a token
+identifying the source and an additional C<void *> with value
+equal to the third argument of the C<isl_flow_foreach> call.
+A dependence is marked I<must> if it originates from a I<must>
+source and if it is not followed by any I<may> sources.
+
+After finishing with an C<isl_flow>, the user should call
+C<isl_flow_free> to free all associated memory.
+
+A higher-level interface to dependence analysis is provided
+by the following function.
+
+	#include <isl/flow.h>
+
+	int isl_union_map_compute_flow(__isl_take isl_union_map *sink,
+		__isl_take isl_union_map *must_source,
+		__isl_take isl_union_map *may_source,
+		__isl_take isl_union_map *schedule,
+		__isl_give isl_union_map **must_dep,
+		__isl_give isl_union_map **may_dep,
+		__isl_give isl_union_map **must_no_source,
+		__isl_give isl_union_map **may_no_source);
+
+The arrays are identified by the tuple names of the ranges
+of the accesses.  The iteration domains by the tuple names
+of the domains of the accesses and of the schedule.
+The relative order of the iteration domains is given by the
+schedule.  The relations returned through C<must_no_source>
+and C<may_no_source> are subsets of C<sink>.
+Any of C<must_dep>, C<may_dep>, C<must_no_source>
+or C<may_no_source> may be C<NULL>, but a C<NULL> value for
+any of the other arguments is treated as an error.
+
+=head3 Interaction with Dependence Analysis
+
+During the dependence analysis, we frequently need to perform
+the following operation.  Given a relation between sink iterations
+and potential source iterations from a particular source domain,
+what is the last potential source iteration corresponding to each
+sink iteration.  It can sometimes be convenient to adjust
+the set of potential source iterations before or after each such operation.
+The prototypical example is fuzzy array dataflow analysis,
+where we need to analyze if, based on data-dependent constraints,
+the sink iteration can ever be executed without one or more of
+the corresponding potential source iterations being executed.
+If so, we can introduce extra parameters and select an unknown
+but fixed source iteration from the potential source iterations.
+To be able to perform such manipulations, C<isl> provides the following
+function.
+
+	#include <isl/flow.h>
+
+	typedef __isl_give isl_restriction *(*isl_access_restrict)(
+		__isl_keep isl_map *source_map,
+		__isl_keep isl_set *sink, void *source_user,
+		void *user);
+	__isl_give isl_access_info *isl_access_info_set_restrict(
+		__isl_take isl_access_info *acc,
+		isl_access_restrict fn, void *user);
+
+The function C<isl_access_info_set_restrict> should be called
+before calling C<isl_access_info_compute_flow> and registers a callback function
+that will be called any time C<isl> is about to compute the last
+potential source.  The first argument is the (reverse) proto-dependence,
+mapping sink iterations to potential source iterations.
+The second argument represents the sink iterations for which
+we want to compute the last source iteration.
+The third argument is the token corresponding to the source
+and the final argument is the token passed to C<isl_access_info_set_restrict>.
+The callback is expected to return a restriction on either the input or
+the output of the operation computing the last potential source.
+If the input needs to be restricted then restrictions are needed
+for both the source and the sink iterations.  The sink iterations
+and the potential source iterations will be intersected with these sets.
+If the output needs to be restricted then only a restriction on the source
+iterations is required.
+If any error occurs, the callback should return C<NULL>.
+An C<isl_restriction> object can be created, freed and inspected
+using the following functions.
+
+	#include <isl/flow.h>
+
+	__isl_give isl_restriction *isl_restriction_input(
+		__isl_take isl_set *source_restr,
+		__isl_take isl_set *sink_restr);
+	__isl_give isl_restriction *isl_restriction_output(
+		__isl_take isl_set *source_restr);
+	__isl_give isl_restriction *isl_restriction_none(
+		__isl_take isl_map *source_map);
+	__isl_give isl_restriction *isl_restriction_empty(
+		__isl_take isl_map *source_map);
+	void *isl_restriction_free(
+		__isl_take isl_restriction *restr);
+	isl_ctx *isl_restriction_get_ctx(
+		__isl_keep isl_restriction *restr);
+
+C<isl_restriction_none> and C<isl_restriction_empty> are special
+cases of C<isl_restriction_input>.  C<isl_restriction_none>
+is essentially equivalent to
+
+	isl_restriction_input(isl_set_universe(
+	    isl_space_range(isl_map_get_space(source_map))),
+			    isl_set_universe(
+	    isl_space_domain(isl_map_get_space(source_map))));
+
+whereas C<isl_restriction_empty> is essentially equivalent to
+
+	isl_restriction_input(isl_set_empty(
+	    isl_space_range(isl_map_get_space(source_map))),
+			    isl_set_universe(
+	    isl_space_domain(isl_map_get_space(source_map))));
+
+=head2 Scheduling
+
+B<The functionality described in this section is fairly new
+and may be subject to change.>
+
+The following function can be used to compute a schedule
+for a union of domains.
+By default, the algorithm used to construct the schedule is similar
+to that of C<Pluto>.
+Alternatively, Feautrier's multi-dimensional scheduling algorithm can
+be selected.
+The generated schedule respects all C<validity> dependences.
+That is, all dependence distances over these dependences in the
+scheduled space are lexicographically positive.
+The default algorithm tries to minimize the dependence distances over
+C<proximity> dependences.
+Moreover, it tries to obtain sequences (bands) of schedule dimensions
+for groups of domains where the dependence distances have only
+non-negative values.
+When using Feautrier's algorithm, the C<proximity> dependence
+distances are only minimized during the extension to a
+full-dimensional schedule.
+
+	#include <isl/schedule.h>
+	__isl_give isl_schedule *isl_union_set_compute_schedule(
+		__isl_take isl_union_set *domain,
+		__isl_take isl_union_map *validity,
+		__isl_take isl_union_map *proximity);
+	void *isl_schedule_free(__isl_take isl_schedule *sched);
+
+A mapping from the domains to the scheduled space can be obtained
+from an C<isl_schedule> using the following function.
+
+	__isl_give isl_union_map *isl_schedule_get_map(
+		__isl_keep isl_schedule *sched);
+
+A representation of the schedule can be printed using
+	 
+	__isl_give isl_printer *isl_printer_print_schedule(
+		__isl_take isl_printer *p,
+		__isl_keep isl_schedule *schedule);
+
+A representation of the schedule as a forest of bands can be obtained
+using the following function.
+
+	__isl_give isl_band_list *isl_schedule_get_band_forest(
+		__isl_keep isl_schedule *schedule);
+
+The individual bands can be visited in depth-first post-order
+using the following function.
+
+	#include <isl/schedule.h>
+	int isl_schedule_foreach_band(
+		__isl_keep isl_schedule *sched,
+		int (*fn)(__isl_keep isl_band *band, void *user),
+		void *user);
+
+The list can be manipulated as explained in L<"Lists">.
+The bands inside the list can be copied and freed using the following
+functions.
+
+	#include <isl/band.h>
+	__isl_give isl_band *isl_band_copy(
+		__isl_keep isl_band *band);
+	void *isl_band_free(__isl_take isl_band *band);
+
+Each band contains zero or more scheduling dimensions.
+These are referred to as the members of the band.
+The section of the schedule that corresponds to the band is
+referred to as the partial schedule of the band.
+For those nodes that participate in a band, the outer scheduling
+dimensions form the prefix schedule, while the inner scheduling
+dimensions form the suffix schedule.
+That is, if we take a cut of the band forest, then the union of
+the concatenations of the prefix, partial and suffix schedules of
+each band in the cut is equal to the entire schedule (modulo
+some possible padding at the end with zero scheduling dimensions).
+The properties of a band can be inspected using the following functions.
+
+	#include <isl/band.h>
+	isl_ctx *isl_band_get_ctx(__isl_keep isl_band *band);
+
+	int isl_band_has_children(__isl_keep isl_band *band);
+	__isl_give isl_band_list *isl_band_get_children(
+		__isl_keep isl_band *band);
+
+	__isl_give isl_union_map *isl_band_get_prefix_schedule(
+		__isl_keep isl_band *band);
+	__isl_give isl_union_map *isl_band_get_partial_schedule(
+		__isl_keep isl_band *band);
+	__isl_give isl_union_map *isl_band_get_suffix_schedule(
+		__isl_keep isl_band *band);
+
+	int isl_band_n_member(__isl_keep isl_band *band);
+	int isl_band_member_is_zero_distance(
+		__isl_keep isl_band *band, int pos);
+
+	int isl_band_list_foreach_band(
+		__isl_keep isl_band_list *list,
+		int (*fn)(__isl_keep isl_band *band, void *user),
+		void *user);
+
+Note that a scheduling dimension is considered to be ``zero
+distance'' if it does not carry any proximity dependences
+within its band.
+That is, if the dependence distances of the proximity
+dependences are all zero in that direction (for fixed
+iterations of outer bands).
+Like C<isl_schedule_foreach_band>,
+the function C<isl_band_list_foreach_band> calls C<fn> on the bands
+in depth-first post-order.
+
+A band can be tiled using the following function.
+
+	#include <isl/band.h>
+	int isl_band_tile(__isl_keep isl_band *band,
+		__isl_take isl_vec *sizes);
+
+	int isl_options_set_tile_scale_tile_loops(isl_ctx *ctx,
+		int val);
+	int isl_options_get_tile_scale_tile_loops(isl_ctx *ctx);
+
+The C<isl_band_tile> function tiles the band using the given tile sizes
+inside its schedule.
+A new child band is created to represent the point loops and it is
+inserted between the modified band and its children.
+The C<tile_scale_tile_loops> option specifies whether the tile
+loops iterators should be scaled by the tile sizes.
+
+A representation of the band can be printed using
+
+	#include <isl/band.h>
+	__isl_give isl_printer *isl_printer_print_band(
+		__isl_take isl_printer *p,
+		__isl_keep isl_band *band);
+
+=head3 Options
+
+	#include <isl/schedule.h>
+	int isl_options_set_schedule_max_coefficient(
+		isl_ctx *ctx, int val);

+=over
+
+=item * schedule_max_coefficient
+
+This option enforces that the coefficients for variable and parameter
+dimensions in the calculated schedule are not larger than the specified value.
+This option can significantly increase the speed of the scheduling calculation
+and may also prevent fusing of unrelated dimensions. A value of -1 means that
+this option does not introduce bounds on the variable or parameter
+coefficients.
+
+=item * schedule_max_constant_term
+
+This option enforces that the constant coefficients in the calculated schedule
+are not larger than the maximal constant term. This option can significantly
+increase the speed of the scheduling calculation and may also prevent fusing of
+unrelated dimensions. A value of -1 means that this option does not introduce
+bounds on the constant coefficients.
+
+=item * schedule_fuse
+
+This option controls the level of fusion.
+If this option is set to C<ISL_SCHEDULE_FUSE_MIN>, then loops in the
+resulting schedule will be distributed as much as possible.
+If this option is set to C<ISL_SCHEDULE_FUSE_MAX>, then C<isl> will
+try to fuse loops in the resulting schedule.
+
+=item * schedule_maximize_band_depth
+
+If this option is set, we do not split bands at the point
+where we detect splitting is necessary. Instead, we
+backtrack and split bands as early as possible. This
+reduces the number of splits and maximizes the width of
+the bands. Wider bands give more possibilities for tiling.
+Note that if the C<schedule_fuse> option is set to C<ISL_SCHEDULE_FUSE_MIN>,
+then bands will be split as early as possible, even if there is no need.
+The C<schedule_maximize_band_depth> option therefore has no effect in this case.
+
+=item * schedule_outer_zero_distance
+
+If this option is set, then we try to construct schedules
+where the outermost scheduling dimension in each band
+results in a zero dependence distance over the proximity
+dependences.
+
+=item * schedule_split_scaled
+
+If this option is set, then we try to construct schedules in which the
+constant term is split off from the linear part if the linear parts of
+the scheduling rows for all nodes in the graphs have a common non-trivial
+divisor.
+The constant term is then placed in a separate band and the linear
+part is reduced.
+
+=item * schedule_algorithm
+
+Selects the scheduling algorithm to be used.
+Available scheduling algorithms are C<ISL_SCHEDULE_ALGORITHM_ISL>
+and C<ISL_SCHEDULE_ALGORITHM_FEAUTRIER>.
+
+=item * schedule_separate_components
+
+If at any point the dependence graph contains any (weakly connected) components,
+then these components are scheduled separately.
+If this option is not set, then some iterations of the domains
+in these components may be scheduled together.
+If this option is set, then the components are given consecutive
+schedules.

+
+=head2 AST Generation
+
+This section describes the C<isl> functionality for generating
+ASTs that visit all the elements
+in a domain in an order specified by a schedule.
+In particular, given a C<isl_union_map>, an AST is generated
+that visits all the elements in the domain of the C<isl_union_map>
+according to the lexicographic order of the corresponding image
+element(s).  If the range of the C<isl_union_map> consists of
+elements in more than one space, then each of these spaces is handled
+separately in an arbitrary order.
+It should be noted that the image elements only specify the I<order>
+in which the corresponding domain elements should be visited.
+No direct relation between the image elements and the loop iterators
+in the generated AST should be assumed.
+
+Each AST is generated within a build.  The initial build
+simply specifies the constraints on the parameters (if any)
+and can be created, inspected, copied and freed using the following functions.
+
+	#include <isl/ast_build.h>
+	__isl_give isl_ast_build *isl_ast_build_from_context(
+		__isl_take isl_set *set);
+	isl_ctx *isl_ast_build_get_ctx(
+		__isl_keep isl_ast_build *build);
+	__isl_give isl_ast_build *isl_ast_build_copy(
+		__isl_keep isl_ast_build *build);
+	void *isl_ast_build_free(
+		__isl_take isl_ast_build *build);
+
+The C<set> argument is usually a parameter set with zero or more parameters.
+More C<isl_ast_build> functions are described in L</"Nested AST Generation">
+and L</"Fine-grained Control over AST Generation">.
+Finally, the AST itself can be constructed using the following
+function.
+
+	#include <isl/ast_build.h>
+	__isl_give isl_ast_node *isl_ast_build_ast_from_schedule(
+		__isl_keep isl_ast_build *build,
+		__isl_take isl_union_map *schedule);
+
+=head3 Inspecting the AST
+
+The basic properties of an AST node can be obtained as follows.

+		__isl_keep isl_ast_node *node);
+	enum isl_ast_node_type isl_ast_node_get_type(
+		__isl_keep isl_ast_node *node);
+
+The type of an AST node is one of
+C<isl_ast_node_for>,
+C<isl_ast_node_if>,
+C<isl_ast_node_block> or
+C<isl_ast_node_user>.
+An C<isl_ast_node_for> represents a for node.
+An C<isl_ast_node_if> represents an if node.
+An C<isl_ast_node_block> represents a compound node.
+An C<isl_ast_node_user> represents an expression statement.
+An expression statement typically corresponds to a domain element, i.e.,
+one of the elements that is visited by the AST.
+
+Each type of node has its own additional properties.

+	int isl_ast_node_for_is_degenerate(
+		__isl_keep isl_ast_node *node);
+
+An C<isl_ast_for> is considered degenerate if it is known to execute
+exactly once.

+
+The type of an AST expression is one of
+C<isl_ast_expr_op>,
+C<isl_ast_expr_id> or
+C<isl_ast_expr_int>.
+An C<isl_ast_expr_op> represents the result of an operation.
+An C<isl_ast_expr_id> represents an identifier.
+An C<isl_ast_expr_int> represents an integer value.
+
+Each type of expression has its own additional properties.

+C<isl_ast_expr_get_op_type> returns the type of the operation

+=item * ast_build_exploit_nested_bounds
+
+Simplify conditions based on bounds of nested for loops.
+In particular, remove conditions that are implied by the fact

+For example, when this option is turned off, AST generation
+for the schedule
+
+	[N,M] -> { A[i,j] -> [i,j] : 0 <= i <= N and

+
+=item * ast_build_group_coscheduled
+
+If two domain elements are assigned the same schedule point, then
+they may be executed in any order and they may even appear in different
+loops.  If this options is set, then the AST generator will make
+sure that coscheduled domain elements do not appear in separate parts
+of the AST.  This is useful in case of nested AST generation
+if the outer AST generation is given only part of a schedule
+and the inner AST generation should handle the domains that are
+coscheduled by this initial part of the schedule together.
+For example if an AST is generated for a schedule
+
+	{ A[i] -> [0]; B[i] -> [0] }
+
+then the C<isl_ast_build_set_create_leaf> callback described
+below may get called twice, once for each domain.
+Setting this option ensures that the callback is only called once
+on both domains together.

+
+This option specifies which bounds to use during separation.
+If this option is set to C<ISL_AST_BUILD_SEPARATION_BOUNDS_IMPLICIT>
+then all (possibly implicit) bounds on the current dimension will
+be used during separation.
+If this option is set to C<ISL_AST_BUILD_SEPARATION_BOUNDS_EXPLICIT>
+then only those bounds that are explicitly available will
+be used during separation.

+to construct if statements with else branches.

+
+=head3 Fine-grained Control over AST Generation
+
+Besides specifying the constraints on the parameters,
+an C<isl_ast_build> object can be used to control
+various aspects of the AST generation process.
+The most prominent way of control is through ``options'',
+which can be set using the following function.
+
+	#include <isl/ast_build.h>
+	__isl_give isl_ast_build *
+	isl_ast_build_set_options(
+		__isl_take isl_ast_build *control,
+		__isl_take isl_union_map *options);
+
+The options are encoded in an <isl_union_map>.
+The domain of this union relation refers to the schedule domain,
+i.e., the range of the schedule passed to C<isl_ast_build_ast_from_schedule>.
+In the case of nested AST generation (see L</"Nested AST Generation">),
+the domain of C<options> should refer to the extra piece of the schedule.
+That is, it should be equal to the range of the wrapped relation in the
+range of the schedule.
+The range of the options can consist of elements in one or more spaces,
+the names of which determine the effect of the option.
+The values of the range typically also refer to the schedule dimension
+to which the option applies.  In case of nested AST generation
+(see L</"Nested AST Generation">), these values refer to the position
+of the schedule dimension within the innermost AST generation.
+The constraints on the domain elements of
+the option should only refer to this dimension and earlier dimensions.
+We consider the following spaces.
+
+=over
+
+=item C<separation_class>
+
+This space is a wrapped relation between two one dimensional spaces.
+The input space represents the schedule dimension to which the option
+applies and the output space represents the separation class.
+While constructing a loop corresponding to the specified schedule
+dimension(s), the AST generator will try to generate separate loops
+for domain elements that are assigned different classes.
+If only some of the elements are assigned a class, then those elements
+that are not assigned any class will be treated as belonging to a class
+that is separate from the explicitly assigned classes.
+The typical use case for this option is to separate full tiles from
+partial tiles.
+The other options, described below, are applied after the separation
+into classes.
+
+As an example, consider the separation into full and partial tiles
+of a tiling of a triangular domain.
+Take, for example, the domain
+
+	{ A[i,j] : 0 <= i,j and i + j <= 100 }
+
+and a tiling into tiles of 10 by 10.  The input to the AST generator
+is then the schedule
+
+	{ A[i,j] -> [([i/10]),[j/10],i,j] : 0 <= i,j and
+						i + j <= 100 }
+
+Without any options, the following AST is generated
+
+	for (int c0 = 0; c0 <= 10; c0 += 1)
+	  for (int c1 = 0; c1 <= -c0 + 10; c1 += 1)
+	    for (int c2 = 10 * c0;
+		 c2 <= min(-10 * c1 + 100, 10 * c0 + 9);
+		 c2 += 1)
+	      for (int c3 = 10 * c1;
+		   c3 <= min(10 * c1 + 9, -c2 + 100);
+		   c3 += 1)
+		A(c2, c3);
+
+Separation into full and partial tiles can be obtained by assigning
+a class, say C<0>, to the full tiles.  The full tiles are represented by those
+values of the first and second schedule dimensions for which there are
+values of the third and fourth dimensions to cover an entire tile.
+That is, we need to specify the following option
+
+	{ [a,b,c,d] -> separation_class[[0]->[0]] :
+		exists b': 0 <= 10a,10b' and
+			   10a+9+10b'+9 <= 100;
+	  [a,b,c,d] -> separation_class[[1]->[0]] :
+		0 <= 10a,10b and 10a+9+10b+9 <= 100 }
+
+which simplifies to
+
+	{ [a, b, c, d] -> separation_class[[1] -> [0]] :
+		a >= 0 and b >= 0 and b <= 8 - a;
+	  [a, b, c, d] -> separation_class[[0] -> [0]] :
+		a >= 0 and a <= 8 }
+
+With this option, the generated AST is as follows
+
+	{
+	  for (int c0 = 0; c0 <= 8; c0 += 1) {
+	    for (int c1 = 0; c1 <= -c0 + 8; c1 += 1)
+	      for (int c2 = 10 * c0;
+		   c2 <= 10 * c0 + 9; c2 += 1)
+		for (int c3 = 10 * c1;
+		     c3 <= 10 * c1 + 9; c3 += 1)
+		  A(c2, c3);
+	    for (int c1 = -c0 + 9; c1 <= -c0 + 10; c1 += 1)
+	      for (int c2 = 10 * c0;
+		   c2 <= min(-10 * c1 + 100, 10 * c0 + 9);
+		   c2 += 1)
+		for (int c3 = 10 * c1;
+		     c3 <= min(-c2 + 100, 10 * c1 + 9);
+		     c3 += 1)
+		  A(c2, c3);
+	  }
+	  for (int c0 = 9; c0 <= 10; c0 += 1)
+	    for (int c1 = 0; c1 <= -c0 + 10; c1 += 1)
+	      for (int c2 = 10 * c0;
+		   c2 <= min(-10 * c1 + 100, 10 * c0 + 9);
+		   c2 += 1)
+		for (int c3 = 10 * c1;
+		     c3 <= min(10 * c1 + 9, -c2 + 100);
+		     c3 += 1)
+		  A(c2, c3);
+	}
+
+=item C<separate>
+
+This is a single-dimensional space representing the schedule dimension(s)
+to which ``separation'' should be applied.  Separation tries to split
+a loop into several pieces if this can avoid the generation of guards
+inside the loop.
+See also the C<atomic> option.
+
+=item C<atomic>
+
+This is a single-dimensional space representing the schedule dimension(s)
+for which the domains should be considered ``atomic''.  That is, the
+AST generator will make sure that any given domain space will only appear
+in a single loop at the specified level.
+
+Consider the following schedule
+
+	{ a[i] -> [i] : 0 <= i < 10;
+	  b[i] -> [i+1] : 0 <= i < 10 }
+
+If the following option is specified
+
+	{ [i] -> separate[x] }
+
+then the following AST will be generated
+
+	{
+	  a(0);
+	  for (int c0 = 1; c0 <= 9; c0 += 1) {
+	    a(c0);
+	    b(c0 - 1);
+	  }
+	  b(9);
+	}
+
+If, on the other hand, the following option is specified
+
+	{ [i] -> atomic[x] }
+
+then the following AST will be generated
+
+	for (int c0 = 0; c0 <= 10; c0 += 1) {
+	  if (c0 <= 9)
+	    a(c0);
+	  if (c0 >= 1)
+	    b(c0 - 1);
+	}
+
+If neither C<atomic> nor C<separate> is specified, then the AST generator
+may produce either of these two results or some intermediate form.
+
+=item C<unroll>
+
+This is a single-dimensional space representing the schedule dimension(s)
+that should be I<completely> unrolled.
+To obtain a partial unrolling, the user should apply an additional
+strip-mining to the schedule and fully unroll the inner loop.
+
+=back
+
+Additional control is available through the following functions.
+
+	#include <isl/ast_build.h>
+	__isl_give isl_ast_build *
+	isl_ast_build_set_iterators(
+		__isl_take isl_ast_build *control,
+		__isl_take isl_id_list *iterators);
+
+The function C<isl_ast_build_set_iterators> allows the user to
+specify a list of iterator C<isl_id>s to be used as iterators.
+If the input schedule is injective, then
+the number of elements in this list should be as large as the dimension
+of the schedule space, but no direct correspondence should be assumed
+between dimensions and elements.
+If the input schedule is not injective, then an additional number
+of C<isl_id>s equal to the largest dimension of the input domains
+may be required.
+If the number of provided C<isl_id>s is insufficient, then additional
+names are automatically generated.
+
+	#include <isl/ast_build.h>

+	isl_ast_build_set_create_leaf(
+		__isl_take isl_ast_build *control,

+			__isl_take isl_ast_build *build,
+			void *user), void *user);
+
+The
+C<isl_ast_build_set_create_leaf> function allows for the
+specification of a callback that should be called whenever the AST
+generator arrives at an element of the schedule domain.
+The callback should return an AST node that should be inserted
+at the corresponding position of the AST.  The default action (when
+the callback is not set) is to continue generating parts of the AST to scan
+all the domain elements associated to the schedule domain element
+and to insert user nodes, ``calling'' the domain element, for each of them.
+The C<build> argument contains the current state of the C<isl_ast_build>.
+To ease nested AST generation (see L</"Nested AST Generation">),
+all control information that is
+specific to the current AST generation such as the options and
+the callbacks has been removed from this C<isl_ast_build>.
+The callback would typically return the result of a nested

+
+The callback set by C<isl_ast_build_set_at_each_domain> will
+be called for each domain AST node.
+The callbacks set by C<isl_ast_build_set_before_each_for>
+and C<isl_ast_build_set_after_each_for> will be called
+for each for AST node.  The first will be called in depth-first
+pre-order, while the second will be called in depth-first post-order.
+Since C<isl_ast_build_set_before_each_for> is called before the for
+node is actually constructed, it is only passed an C<isl_ast_build>.
+The returned C<isl_id> will be added as an annotation (using
+C<isl_ast_node_set_annotation>) to the constructed for node.
+In particular, if the user has also specified an C<after_each_for>
+callback, then the annotation can be retrieved from the node passed to
+that callback using C<isl_ast_node_get_annotation>.
+All callbacks should C<NULL> on failure.
+The given C<isl_ast_build> can be used to create new
+C<isl_ast_expr> objects using C<isl_ast_build_expr_from_pw_aff>
+or C<isl_ast_build_call_from_pw_multi_aff>.
+
+=head3 Nested AST Generation
+
+C<isl> allows the user to create an AST within the context
+of another AST.  These nested ASTs are created using the
+same C<isl_ast_build_ast_from_schedule> function that is used to create the
+outer AST.  The C<build> argument should be an C<isl_ast_build>
+passed to a callback set by
+C<isl_ast_build_set_create_leaf>.
+The space of the range of the C<schedule> argument should refer
+to this build.  In particular, the space should be a wrapped
+relation and the domain of this wrapped relation should be the
+same as that of the range of the schedule returned by
+C<isl_ast_build_get_schedule> below.
+In practice, the new schedule is typically
+created by calling C<isl_union_map_range_product> on the old schedule
+and some extra piece of the schedule.
+The space of the schedule domain is also available from
+the C<isl_ast_build>.
+
+	#include <isl/ast_build.h>
+	__isl_give isl_union_map *isl_ast_build_get_schedule(
+		__isl_keep isl_ast_build *build);
+	__isl_give isl_space *isl_ast_build_get_schedule_space(
+		__isl_keep isl_ast_build *build);
+	__isl_give isl_ast_build *isl_ast_build_restrict(
+		__isl_take isl_ast_build *build,
+		__isl_take isl_set *set);
+
+The C<isl_ast_build_get_schedule> function returns a (partial)
+schedule for the domains elements for which part of the AST still needs to
+be generated in the current build.
+In particular, the domain elements are mapped to those iterations of the loops
+enclosing the current point of the AST generation inside which
+the domain elements are executed.
+No direct correspondence between
+the input schedule and this schedule should be assumed.
+The space obtained from C<isl_ast_build_get_schedule_space> can be used
+to create a set for C<isl_ast_build_restrict> to intersect
+with the current build.  In particular, the set passed to
+C<isl_ast_build_restrict> can have additional parameters.
+The ids of the set dimensions in the space returned by
+C<isl_ast_build_get_schedule_space> correspond to the
+iterators of the already generated loops.
+The user should not rely on the ids of the output dimensions
+of the relations in the union relation returned by
+C<isl_ast_build_get_schedule> having any particular value.
+
+=head1 Applications
+
+Although C<isl> is mainly meant to be used as a library,
+it also contains some basic applications that use some
+of the functionality of C<isl>.
+The input may be specified in either the L<isl format>
+or the L<PolyLib format>.
+
+=head2 C<isl_polyhedron_sample>
+
+C<isl_polyhedron_sample> takes a polyhedron as input and prints
+an integer element of the polyhedron, if there is any.
+The first column in the output is the denominator and is always
+equal to 1.  If the polyhedron contains no integer points,
+then a vector of length zero is printed.
+
+=head2 C<isl_pip>
+
+C<isl_pip> takes the same input as the C<example> program
+from the C<piplib> distribution, i.e., a set of constraints
+on the parameters, a line containing only -1 and finally a set
+of constraints on a parametric polyhedron.
+The coefficients of the parameters appear in the last columns
+(but before the final constant column).
+The output is the lexicographic minimum of the parametric polyhedron.
+As C<isl> currently does not have its own output format, the output
+is just a dump of the internal state.
+
+=head2 C<isl_polyhedron_minimize>
+
+C<isl_polyhedron_minimize> computes the minimum of some linear
+or affine objective function over the integer points in a polyhedron.
+If an affine objective function
+is given, then the constant should appear in the last column.
+
+=head2 C<isl_polytope_scan>
+
+Given a polytope, C<isl_polytope_scan> prints
+all integer points in the polytope.
+
+=head2 C<isl_codegen>
+
+Given a schedule, a context set and an options relation,
+C<isl_codegen> prints out an AST that scans the domain elements
+of the schedule in the order of their image(s) taking into account
+the constraints in the context set.

+ * operation will decrease the reference count and only actually release
+ * the structures when the reference count drops to zero.
+ *
+ * Functions that return an isa structure will in general _destroy_
+ * all argument isa structures (the obvious execption begin the _copy
+ * functions).  A pointer passed to such a function may therefore
+ * never be used after the function call.  If you want to keep a

+/* An isl_ast_build represents the context in which AST is being
+ * generated.  That is, it (mostly) contains information about outer
+ * loops that can be used to simplify inner loops.
+ *
+ * "domain" represents constraints on the internal schedule domain,
+ * corresponding to the context of the AST generation and the constraints
+ * implied by the loops that have already been generated.
+ * When an isl_ast_build is first created, outside any AST generation,
+ * the domain is typically a parameter set.  It is only when a AST
+ * generation phase is initiated that the domain of the isl_ast_build
+ * is changed to refer to the internal schedule domain.
+ * The domain then lives in a space of the form
+ *
+ *	S
+ *
+ *  or
+ *
+ *	[O -> S]
+ *
+ * O represents the loops generated in outer AST generations.
+ * S represents the loops (both generated and to be generated)
+ * of the current AST generation.
+ * Both include eliminated loops.
+ * "domain" is expected not to have any unknown divs because
+ * it is used as the context argument in a call to isl_basic_set_gist
+ * in isl_ast_build_compute_gist_basic_set.
+ *
+ * "depth" is equal to the number of loops that have already
+ * been generated (including those in outer AST generations).
+ * "outer_pos" is equal to the number of loops in outer AST generations.
+ *
+ * "generated" is a superset of "domain" corresponding to those
+ * constraints that were either given by the user or that have
+ * effectively been generated (as bounds on a for loop).
+ *
+ * "pending" is a superset of "domain" corresponding to the constraints
+ * that still need to be generated (as guards), but that may end up
+ * not getting generated if they are implied by any constraints
+ * enforced by inner loops.
+ *
+ * "strides" contains the stride of each loop.  The number of elements
+ * is equal to the number of dimensions in "domain".
+ * "offsets" constains the offsets of strided loops.  If s is the stride
+ * for a given dimension and f is the corresponding offset, then the
+ * dimension takes on values
+ *
+ *	f + s a
+ *
+ * with a an integer.  For non-strided loops, the offset is zero.
+ *
+ * "iterators" contains the loop iterators of both generated and
+ * to be generated loops.  The number of elements is at least as
+ * large as the dimension of the internal schedule domain.  The
+ * number may be larger, in which case the additional ids can be
+ * used in a nested AST generation should the schedule be non-injective.
+ *
+ * "values" lives in the space
+ *
+ *	[O -> S] -> [O -> S]		(or S -> S)
+ *
+ * and expresses (if possible) loop iterators in terms of parameters
+ * and outer loop iterators.  If the value of a given loop iterator
+ * cannot be expressed as an affine expression (either because the iterator
+ * attains multiple values or because the single value is a piecewise
+ * affine expression), then it is expressed in "values" as being equal
+ * to itself.
+ *
+ * "value" is the value of the loop iterator at the current depth.
+ * It is NULL if it has not been computed yet or if the value of the
+ * given loop iterator cannot be expressed as a piecewise affine expression
+ * (because the iterator attains multiple values).
+ *
+ * "schedule_map" maps the internal schedule domain to the external schedule
+ * domain.  It may be NULL if it hasn't been computed yet.
+ * See isl_ast_build_get_schedule_map_multi_aff.
+ *
+ * The "create_leaf" callback is called for every leaf in the generated AST.
+ * The callback is responsible for creating the node to be placed at those
+ * leaves.  If this callback is not set, then isl will generated user
+ * nodes with call expressions corresponding to an element of the domain.
+ *
+ * The "at_each_domain" callback is called on every node created to represent
+ * an element of the domain.  Each of these nodes is a user node
+ * with as expression a call expression.
+ *
+ * The "before_each_for" callback is called on each for node before
+ * its children have been created.
+ *
+ * The "after_each_for" callback is called on each for node after
+ * its children have been created.
+ *
+ * "executed" contains the inverse schedule at this point
+ * of the AST generation.
+ * It is currently only used in isl_ast_build_get_schedule, which is
+ * in turn only used by user code from within a callback.
+ * The value is set right before we may be calling such a callback.

+ * a < c and b > d.  This means that either the interval spanned

+ * The component inverse schedule is specified as the "map" fields

+ *
+ * This function may modify the "set" fields of "domain".
+ *
+ * Before proceeding with the actual code generation for the component,
+ * we first check if there are any "shifted" strides, meaning that
+ * the schedule domains of the individual domains are all strided,
+ * but that they have different offsets, resulting in the union
+ * of schedule domains not being strided anymore.
+ *
+ * The simplest example is the schedule
+ *
+ *	{ A[i] -> [2i]: 0 <= i < 10; B[i] -> [2i+1] : 0 <= i < 10 }
+ *
+ * Both schedule domains are strided, but their union is not.
+ * This function detects such cases and then rewrites the schedule to
+ *
+ *	{ A[i] -> [2i, 0]: 0 <= i < 10; B[i] -> [2i, 1] : 0 <= i < 10 }
+ *
+ * In the new schedule, the schedule domains have the same offset (modulo
+ * the stride), ensuring that the union of schedule domains is also strided.
+ *
+ *
+ * If there is only a single domain in the component, then there is
+ * nothing to do.   Similarly, if the current schedule dimension has
+ * a fixed value for almost all domains then there is nothing to be done.
+ * In particular, we need at least two domains where the current schedule
+ * dimension does not have a fixed value.
+ * Finally, if any of the options refer to the current schedule dimension,
+ * then we bail out as well.  It would be possible to reformulate the options
+ * in terms of the new schedule domain, but that would introduce constraints
+ * that separate the domains in the options and that is something we would
+ * like to avoid.
+ *
+ *
+ * To see if there is any shifted stride, we look at the differences
+ * between the values of the current dimension in pairs of domains
+ * for equal values of outer dimensions.  These differences should be
+ * of the form
+ *
+ *	m x + r
+ *
+ * with "m" the stride and "r" a constant.  Note that we cannot perform
+ * this analysis on individual domains as the lower bound in each domain
+ * may depend on parameters or outer dimensions and so the current dimension
+ * itself may not have a fixed remainder on division by the stride.
+ *
+ * In particular, we compare the first domain that does not have an
+ * obviously fixed value for the current dimension to itself and all
+ * other domains and collect the offsets and the gcd of the strides.
+ * If the gcd becomes one, then we failed to find shifted strides.
+ * If all the offsets are the same (for those domains that do not have
+ * an obviously fixed value for the current dimension), then we do not
+ * apply the transformation.
+ * If none of the domains were skipped, then there is nothing to do.
+ * If some of them were skipped, then if we apply separation, the schedule
+ * domain should get split in pieces with a (non-shifted) stride.
+ *
+ * Otherwise, we apply a shift to expose the stride in
+ * generate_shift_component.

+ *
+ * We turn this problem into the computation of a convex hull of a pair
+ * _bounded_ polyhedra by "changing the direction of the homogeneous
+ * dimension".  This idea is due to Matthias Koeppe.
+ *
+ * Consider the cones in homogeneous space that correspond to the
+ * input polyhedra.  The rays of these cones are also rays of the
+ * polyhedra if the coordinate that corresponds to the homogeneous
+ * dimension is zero.  That is, if the inner product of the rays
+ * with the homogeneous direction is zero.
+ * The cones in the homogeneous space can also be considered to
+ * correspond to other pairs of polyhedra by chosing a different
+ * homogeneous direction.  To ensure that both of these polyhedra
+ * are bounded, we need to make sure that all rays of the cones
+ * correspond to vertices and not to rays.
+ * Let s be a direction such that <s, r> > 0 for all rays r of both cones.
+ * Then using s as a homogeneous direction, we obtain a pair of polytopes.
+ * The vector s is computed in valid_direction.
+ *
+ * Note that we need to consider _all_ rays of the cones and not just
+ * the rays that correspond to rays in the polyhedra.  If we were to
+ * only consider those rays and turn them into vertices, then we
+ * may inadvertently turn some vertices into rays.
+ *
+ * The standard homogeneous direction is the unit vector in the 0th coordinate.
+ * We therefore transform the two polyhedra such that the selected
+ * direction is mapped onto this standard direction and then proceed
+ * with the normal computation.
+ * Let S be a non-singular square matrix with s as its first row,
+ * then we want to map the polyhedra to the space
+ *
+ *	[ y' ]     [ y ]		[ y ]          [ y' ]
+ *	[ x' ] = S [ x ]	i.e.,	[ x ] = S^{-1} [ x' ]
+ *
+ * We take S to be the unimodular completion of s to limit the growth
+ * of the coefficients in the following computations.
+ *
+ * Let b_i + A_i x >= 0 be the constraints of polyhedron i.
+ * We first move to the homogeneous dimension
+ *
+ *	b_i y + A_i x >= 0		[ b_i A_i ] [ y ]    [ 0 ]
+ *	    y         >= 0	or	[  1   0  ] [ x ] >= [ 0 ]
+ *
+ * Then we change directoin
+ *
+ *	[ b_i A_i ]        [ y' ]		              [ y' ]
+ *	[  1   0  ] S^{-1} [ x' ] >= 0	or	[ b_i' A_i' ] [ x' ] >= 0
+ *
+ * Then we compute the convex hull of the polytopes b_i' + A_i' x' >= 0
+ * resulting in b' + A' x' >= 0, which we then convert back
+ *
+ *	            [ y ]		        [ y ]
+ *	[ b' A' ] S [ x ] >= 0	or	[ b A ] [ x ] >= 0
+ *

+ * this function returns an affine transformation T,
+ *
+ *		y = T y'
+ *
+ * that bijectively maps the integer vectors y' to integer
+ * vectors y that satisfy the modulo constraints.
+ *
+ * This function is inspired by Section 2.5.3
+ * of B. Meister, "Stating and Manipulating Periodicity in the Polytope
+ * Model.  Applications to Program Analysis and Optimization".
+ * However, the implementation only follows the algorithm of that
+ * section for computing a particular solution and not for computing
+ * a general homogeneous solution.  The latter is incomplete and
+ * may remove some valid solutions.
+ * Instead, we use an adaptation of the algorithm in Section 7 of
+ * B. Meister, S. Verdoolaege, "Polynomial Approximations in the Polytope
+ * Model: Bringing the Power of Quasi-Polynomials to the Masses".
+ *
+ * The input is given as a matrix B = [ c A ] and a vector d.
+ * Each element of the vector d corresponds to a row in B.
+ * The output is a lower triangular matrix.
+ * If no integer vector y satisfies the given constraints then
+ * a matrix with zero columns is returned.
+ *
+ * We first compute a particular solution y_0 to the given set of
+ * modulo constraints in particular_solution.  If no such solution
+ * exists, then we return a zero-columned transformation matrix.
+ * Otherwise, we compute the generic solution to
+ *
+ *		A y = 0 mod d
+ *
+ * That is we want to compute G such that
+ *
+ *		y = G y''
+ *
+ * with y'' integer, describes the set of solutions.
+ *
+ * We first remove the common factors of each row.
+ * In particular if gcd(A_i,d_i) != 1, then we divide the whole
+ * row i (including d_i) by this common factor.  If afterwards gcd(A_i) != 1,
+ * then we divide this row of A by the common factor, unless gcd(A_i) = 0.
+ * In the later case, we simply drop the row (in both A and d).
+ *
+ * If there are no rows left in A, then G is the identity matrix. Otherwise,
+ * for each row i, we now determine the lattice of integer vectors
+ * that satisfies this row.  Let U_i be the unimodular extension of the
+ * row A_i.  This unimodular extension exists because gcd(A_i) = 1.
+ * The first component of
+ *
+ *		y' = U_i y
+ *
+ * needs to be a multiple of d_i.  Let y' = diag(d_i, 1, ..., 1) y''.
+ * Then,
+ *
+ *		y = U_i^{-1} diag(d_i, 1, ..., 1) y''
+ *
+ * for arbitrary integer vectors y''.  That is, y belongs to the lattice
+ * generated by the columns of L_i = U_i^{-1} diag(d_i, 1, ..., 1).
+ * If there is only one row, then G = L_1.
+ *
+ * If there is more than one row left, we need to compute the intersection
+ * of the lattices.  That is, we need to compute an L such that
+ *
+ *		L = L_i L_i'	for all i
+ *
+ * with L_i' some integer matrices.  Let A be constructed as follows
+ *
+ *		A = [ L_1^{-T} L_2^{-T} ... L_k^{-T} ]
+ *
+ * and computed the Hermite Normal Form of A = [ H 0 ] U
+ * Then,
+ *
+ *		L_i^{-T} = H U_{1,i}
+ *
+ * or
+ *
+ *		H^{-T} = L_i U_{1,i}^T
+ *
+ * In other words G = L = H^{-T}.
+ * To ensure that G is lower triangular, we compute and use its Hermite
+ * normal form.
+ *
+ * The affine transformation matrix returned is then
+ *
+ *		[  1   0  ]
+ *		[ y_0  G  ]
+ *
+ * as any y = y_0 + G y' with y' integer is a solution to the original
+ * modulo constraints.

+ *			compute last iteration of w2 between the source and sink
+ *								of dep
+ *			add result to possible last accesses at level l of write w2
+ *			and replace possible last accesses dep by the remainder
+ *
+ *
+ * The above algorithm is applied to the must access.  During the course

+ * been matched to may accesses (maydo).
+ * At the end of each level, we also consider the may accesses.
+ * In particular, we consider may accesses that precede the remaining

+/* Given a map "map", compute the lexicographically minimal
+ * (or maximal) image element for each domain element in dom.
+ * Set *empty to those elements in dom that do not have an image element.
+ *
+ * We first compute the lexicographically minimal or maximal element
+ * in the first basic map.  This results in a partial solution "res"
+ * and a subset "todo" of dom that still need to be handled.
+ * We then consider each of the remaining maps in "map" and successively
+ * update both "res" and "todo".
+ *
+ * Let res^k and todo^k be the results after k steps and let i = k + 1.
+ * Assume we are computing the lexicographical maximum.
+ * We first compute the lexicographically maximal element in basic map i.
+ * This results in a partial solution res_i and a subset todo_i.
+ * Then we combine these results with those obtain for the first k basic maps
+ * to obtain a result that is valid for the first k+1 basic maps.
+ * In particular, the set where there is no solution is the set where
+ * there is no solution for the first k basic maps and also no solution
+ * for the ith basic map, i.e.,
+ *
+ *	todo^i = todo^k * todo_i
+ *
+ * On dom(res^k) * dom(res_i), we need to pick the larger of the two
+ * solutions, arbitrarily breaking ties in favor of res^k.
+ * That is, when res^k(a) >= res_i(a), we pick res^k and
+ * when res^k(a) < res_i(a), we pick res_i.  (Here, ">=" and "<" denote
+ * the lexicographic order.)
+ * In practice, we compute
+ *
+ *	res^k * (res_i . "<=")
+ *
+ * and
+ *
+ *	res_i * (res^k . "<")
+ *
+ * Finally, we consider the symmetric difference of dom(res^k) and dom(res_i),
+ * where only one of res^k and res_i provides a solution and we simply pick
+ * that one, i.e.,
+ *
+ *	res^k * todo_i
+ * and
+ *	res_i * todo^k
+ *
+ * Note that we only compute these intersections when dom(res^k) intersects
+ * dom(res_i).  Otherwise, the only effect of these intersections is to
+ * potentially break up res^k and res_i into smaller pieces.
+ * We want to avoid such splintering as much as possible.
+ * In fact, an earlier implementation of this function would look for
+ * better results in the domain of res^k and for extra results in todo^k,
+ * but this would always result in a splintering according to todo^k,
+ * even when the domain of basic map i is disjoint from the domains of
+ * the previous basic maps.

+ *
+ * with G a lower-triangular matrix with all elements below the diagonal
+ * non-negative and smaller than the diagonal element on the same row.
+ * We first normalize x_0 by making the same property hold in the affine
+ * T matrix.
+ * The rows i of G with a 1 on the diagonal do not impose any modulo
+ * constraint and simply express x_i = x'_i.
+ * For each of the remaining rows i, we introduce a div and a corresponding
+ * equality.  In particular
+ *
+ *	g_ii e_j = x_i - g_i(x')
+ *
+ * where each x'_k is replaced either by x_k (if g_kk = 1) or the
+ * corresponding div (if g_kk != 1).
+ *
+ * If there are any equalities not involving any div, then we
+ * first apply a variable compression on the variables x:
+ *
+ *	x = C x''	x'' = C_2 x
+ *
+ * and perform the above parameter compression on A C instead of on A.
+ * The resulting compression is then of the form
+ *
+ *	x'' = T(x') = x_0 + G x'
+ *
+ * and in constructing the new divs and the corresponding equalities,

+ *
+ * This function is a slight generalization of isl_mat_variable_compression

+ *
+ * We first select the equalities of interest, that is those that involve

+ * Denote those equalities as
+ *
+ *		-C(p) + M x = 0
+ *
+ * where C(p) depends on the parameters if type == isl_dim_set and
+ * is a constant if type == isl_dim_param.
+ *
+ * First compute the (left) Hermite normal form of M,
+ *
+ *		M [U1 U2] = M U = H = [H1 0]
+ * or
+ *		              M = H Q = [H1 0] [Q1]

+ * Define the transformed variables as

+ *		x = [U1 U2] [ x1' ] = [U1 U2] [Q1] x
+ *		            [ x2' ]           [Q2]
+ *
+ * The equalities then become
+ *
+ *		-C(p) + H1 x1' = 0   or   x1' = H1^{-1} C(p) = C'(p)
+ *
+ * If the denominator of the constant term does not divide the
+ * the common denominator of the parametric terms, then every
+ * integer point is mapped to a non-integer point and then the original set has no
+ * integer solutions (since the x' are a unimodular transformation
+ * of the x).  In this case, an empty morphism is returned.
+ * Otherwise, the transformation is given by
+ *
+ *		x = U1 H1^{-1} C(p) + U2 x2'

+ * attained by a basis vector, where an initial basis may have been set
+ * by the calling function.  Otherwise an initial basis that exploits
+ * the equalities in the tableau is created.
+ * tab->n_zero is currently ignored and is clobbered by this function.
+ *
+ * The tableau is allowed to have unbounded direction, but then
+ * the calling function needs to set an initial basis, with the
+ * unbounded directions last and with tab->n_unbounded set
+ * to the number of unbounded directions.
+ * Furthermore, the calling functions needs to add shifted copies
+ * of all constraints involving unbounded directions to ensure
+ * that any feasible rational value in these directions can be rounded
+ * up to yield a feasible integer value.
+ * In particular, let B define the given basis x' = B x
+ * and let T be the inverse of B, i.e., X = T x'.
+ * Let a x + c >= 0 be a constraint of the set represented by the tableau,
+ * or a T x' + c >= 0 in terms of the given basis.  Assume that
+ * the bounded directions have an integer value, then we can safely
+ * round up the values for the unbounded directions if we make sure
+ * that x' not only satisfies the original constraint, but also
+ * the constraint "a T x' + c + s >= 0" with s the sum of all
+ * negative values in the last n_unbounded entries of "a T".
+ * The calling function therefore needs to add the constraint
+ * a x + c + s >= 0.  The current function then scans the first
+ * directions for an integer value and once those have been found,
+ * it can compute "T ceil(B x)" to yield an integer point in the set.
+ * Note that during the search, the first rows of B may be changed
+ * by a basis reduction, but the last n_unbounded rows of B remain
+ * unaltered and are also not mixed into the first rows.
+ *
+ * The search is implemented iteratively.  "level" identifies the current
+ * basis vector.  "init" is true if we want the first value at the current
+ * level and false if we want the next value.
+ *
+ * At the start of each level, we first check if we can find a solution
+ * using greedy search.  If not, we continue with the exhaustive search.
+ *
+ * The initial basis is the identity matrix.  If the range in some direction
+ * contains more than one integer value, we perform basis reduction based
+ * on the value of ctx->opt->gbr
+ *	- ISL_GBR_NEVER:	never perform basis reduction
+ *	- ISL_GBR_ONCE:		only perform basis reduction the first
+ *				time such a range is encountered
+ *	- ISL_GBR_ALWAYS:	always perform basis reduction when
+ *				such a range is encountered
+ *
+ * When ctx->opt->gbr is set to ISL_GBR_ALWAYS, then we allow the basis
+ * reduction computation to return early.  That is, as soon as it

+ * The "row_var" and "col_var" arrays map column and row indices
+ * to indices in the "var" and "con" arrays.  The elements of these
+ * arrays maintain extra information about the variables and the constraints.
+ * Each row expresses the corresponding row variable as an affine expression
+ * of the column variables.
+ * The first two columns in the matrix contain the common denominator of
+ * the row and the numerator of the constant term.
+ * If "M" is set, then the third column represents the "big parameter".
+ * The third (M = 0) or fourth (M = 1) column
+ * in the matrix is called column 0 with respect to the col_var array.
+ * The sample value of the tableau is the value that assigns zero
+ * to all the column variables and the constant term of each affine
+ * expression to the corresponding row variable.
+ * The operations on the tableau maintain the property that the sample
+ * value satisfies the non-negativity constraints (usually on the slack
+ * variables).
+ *
+ * The big parameter represents an arbitrarily big (and divisible)
+ * positive number.  If present, then the sign of a row is determined
+ * lexicographically, with the sign of the big parameter coefficient
+ * considered first.  The big parameter is only used while
+ * solving PILP problems.
+ *
+ * The first n_dead column variables have their values fixed to zero.
+ * The corresponding tab_vars are flagged "is_zero".
+ * Some of the rows that have have zero coefficients in all but
+ * the dead columns are also flagged "is_zero".
+ *
+ * The first n_redundant rows correspond to inequality constraints
+ * that are always satisfied for any value satisfying the non-redundant
+ * rows.  The corresponding tab_vars are flagged "is_redundant".
+ * A row variable that is flagged "is_zero" is also flagged "is_redundant"
+ * since the constraint has been reduced to 0 = 0 and is therefore always
+ * satisfied.
+ *
+ * There are "n_var" variables in total.  The first "n_param" of these
+ * are called parameters and the last "n_div" of these are called divs.
+ * The basic tableau operations makes no distinction between different
+ * kinds of variables.  These special variables are only used while
+ * solving PILP problems.
+ *
+ * Dead columns and redundant rows are detected on the fly.
+ * However, the basic operations do not ensure that all dead columns
+ * or all redundant rows are detected.
+ * isl_tab_detect_implicit_equalities and isl_tab_detect_redundant can be used
+ * to perform and exhaustive search for dead columns and redundant rows.
+ *
+ * The samples matrix contains "n_sample" integer points that have at some
+ * point been elements satisfying the tableau.  The first "n_outside"
+ * of them no longer satisfy the tableau.  They are kept because they
+ * can be reinstated during rollback when the constraint that cut them
+ * out is removed.  These samples are only maintained for the context
+ * tableau while solving PILP problems.
+ *
+ * If "preserve" is set, then we want to keep all constraints in the
+ * tableau, even if they turn out to be redundant.

+ * The implementation of parametric integer linear programming in this file
+ * was inspired by the paper "Parametric Integer Programming" and the
+ * report "Solving systems of affine (in)equalities" by Paul Feautrier
+ * (and others).
+ *
+ * The strategy used for obtaining a feasible solution is different
+ * from the one used in isl_tab.c.  In particular, in isl_tab.c,
+ * upon finding a constraint that is not yet satisfied, we pivot
+ * in a row that increases the constant term of the row holding the
+ * constraint, making sure the sample solution remains feasible
+ * for all the constraints it already satisfied.
+ * Here, we always pivot in the row holding the constraint,
+ * choosing a column that induces the lexicographically smallest
+ * increment to the sample solution.
+ *
+ * By starting out from a sample value that is lexicographically
+ * smaller than any integer point in the problem space, the first
+ * feasible integer sample point we find will also be the lexicographically
+ * smallest.  If all variables can be assumed to be non-negative,
+ * then the initial sample value may be chosen equal to zero.
+ * However, we will not make this assumption.  Instead, we apply
+ * the "big parameter" trick.  Any variable x is then not directly
+ * used in the tableau, but instead it is represented by another
+ * variable x' = M + x, where M is an arbitrarily large (positive)
+ * value.  x' is therefore always non-negative, whatever the value of x.
+ * Taking as initial sample value x' = 0 corresponds to x = -M,
+ * which is always smaller than any possible value of x.
+ *
+ * The big parameter trick is used in the main tableau and
+ * also in the context tableau if isl_context_lex is used.
+ * In this case, each tableaus has its own big parameter.
+ * Before doing any real work, we check if all the parameters
+ * happen to be non-negative.  If so, we drop the column corresponding
+ * to M from the initial context tableau.
+ * If isl_context_gbr is used, then the big parameter trick is only
+ * used in the main tableau.

+ *
+ * If none of these cases hold, we check the value of the row for each

+ *	>0 ?	     Y      N	 Y     N
+ *		    any    neg  any   neg
+ *
+ * There is no special sign for "zero", because we can usually treat zero
+ * as either non-negative or non-positive, whatever works out best.
+ * However, if the row is "critical", meaning that pivoting is impossible
+ * then we don't want to limp zero with the non-positive case, because
+ * then we we would lose the solution for those values of the parameters
+ * where the value of the row is zero.  Instead, we treat 0 as non-negative
+ * ensuring a split if the row can attain both zero and negative values.
+ * The same happens when the original constraint was one that could not
+ * be satisfied with equality by any integer values of the parameters.
+ * In this case, we normalize the constraint, but then a value of zero
+ * for the normalized constraint is actually a positive value for the
+ * original constraint, so again we need to treat zero as non-negative.

+ *	both negative and non-negative	->	all
+ *
+ *	samples	       neg	          	       pos

+ * be infeasible.  Some pivots may need to be performed for only some
+ * feasible values of the context tableau.  If so, the context tableau
+ * is split into a part where the pivot is needed and a part where it is not.
+ *
+ * Whenever we enter the main loop, the main tableau is such that no
+ * "obvious" pivots need to be performed on it, where "obvious" means
+ * that the given row can be seen to be negative without looking at
+ * the context tableau.  In particular, for non-parametric problems,
+ * no pivots need to be performed on the main tableau.
+ * The caller of find_solutions is responsible for making this property
+ * hold prior to the first iteration of the loop, while restore_lexmin
+ * is called before every other iteration.
+ *
+ * Inside the main loop, we first examine the signs of the rows of
+ * the main tableau within the context of the context tableau.
+ * If we find a row that is always non-positive for all values of
+ * the parameters satisfying the context tableau and negative for at
+ * least one value of the parameters, we perform the appropriate pivot
+ * and start over.  An exception is the case where no pivot can be
+ * performed on the row.  In this case, we require that the sign of
+ * the row is negative for all values of the parameters (rather than just
+ * non-positive).  This special case is handled inside row_sign, which
+ * will say that the row can have any sign if it determines that it can
+ * attain both negative and zero values.
+ *
+ * If we can't find a row that always requires a pivot, but we can find
+ * one or more rows that require a pivot for some values of the parameters
+ * (i.e., the row can attain both positive and negative signs), then we split
+ * the context tableau into two parts, one where we force the sign to be
+ * non-negative and one where we force is to be negative.
+ * The non-negative part is handled by a recursive call (through find_in_pos).
+ * Upon returning from this call, we continue with the negative part and
+ * perform the required pivot.
+ *
+ * If no such rows can be found, all rows are non-negative and we have
+ * found a (rational) feasible point.  If we only wanted a rational point
+ * then we are done.
+ * Otherwise, we check if all values of the sample point of the tableau
+ * are integral for the variables.  If so, we have found the minimal
+ * integral point and we are done.
+ * If the sample point is not integral, then we need to make a distinction
+ * based on whether the constant term is non-integral or the coefficients
+ * of the parameters.  Furthermore, in order to decide how to handle
+ * the non-integrality, we also need to know whether the coefficients
+ * of the other columns in the tableau are integral.  This leads
+ * to the following table.  The first two rows do not correspond
+ * to a non-integral sample point and are only mentioned for completeness.
+ *
+ *	constant	parameters	other
+ *
+ *	int		int		int	|
+ *	int		int		rat	| -> no problem
+ *
+ *	rat		int		int	  -> fail
+ *
+ *	rat		int		rat	  -> cut
+ *
+ *	int		rat		rat	|
+ *	rat		rat		rat	| -> parametric cut
+ *
+ *	int		rat		int	|
+ *	rat		rat		int	| -> split context
+ *
+ * If the parametric constant is completely integral, then there is nothing
+ * to be done.  If the constant term is non-integral, but all the other
+ * coefficient are integral, then there is nothing that can be done
+ * and the tableau has no integral solution.
+ * If, on the other hand, one or more of the other columns have rational
+ * coefficients, but the parameter coefficients are all integral, then
+ * we can perform a regular (non-parametric) cut.
+ * Finally, if there is any parameter coefficient that is non-integral,
+ * then we need to involve the context tableau.  There are two cases here.
+ * If at least one other column has a rational coefficient, then we
+ * can perform a parametric cut in the main tableau by adding a new
+ * integer division in the context tableau.
+ * If all other columns have integral coefficients, then we need to
+ * enforce that the rational combination of parameters (c + \sum a_i y_i)/m
+ * is always integral.  We do this by introducing an integer division
+ * q = floor((c + \sum a_i y_i)/m) and stipulating that its argument should
+ * always be integral in the context tableau, i.e., m q = c + \sum a_i y_i.
+ * Since q is expressed in the tableau as
+ *	c + \sum a_i y_i - m q >= 0
+ *	-c - \sum a_i y_i + m q + m - 1 >= 0
+ * it is sufficient to add the inequality
+ *	-c - \sum a_i y_i + m q >= 0
+ * In the part of the context where this inequality does not hold, the
+ * main tableau is marked as being empty.

+# SYNOPSIS
+#
+#   AX_CC_MAXOPT
+#
+# DESCRIPTION
+#
+#   Try to turn on "good" C optimization flags for various compilers and
+#   architectures, for some definition of "good". (In our case, good for
+#   FFTW and hopefully for other scientific codes. Modify as needed.)
+#
+#   The user can override the flags by setting the CFLAGS environment
+#   variable. The user can also specify --enable-portable-binary in order to
+#   disable any optimization flags that might result in a binary that only
+#   runs on the host architecture.
+#
+#   Note also that the flags assume that ANSI C aliasing rules are followed
+#   by the code (e.g. for gcc's -fstrict-aliasing), and that floating-point
+#   computations can be re-ordered as needed.
+#
+#   Requires macros: AX_CHECK_COMPILER_FLAGS, AX_COMPILER_VENDOR,
+#   AX_GCC_ARCHFLAG, AX_GCC_X86_CPUID.

+# SYNOPSIS

+#   AX_CREATE_PKGCONFIG_INFO [(outputfile, [requires [,libs [,summary [,cflags [, ldflags]]]]])]
+#
+# DESCRIPTION
+#
+#   Defaults:
+#
+#     $1 = $PACKAGE_NAME.pc
+#     $2 = (empty)
+#     $3 = $PACKAGE_LIBS $LIBS (as set at that point in configure.ac)
+#     $4 = $PACKAGE_SUMMARY (or $1 Library)
+#     $5 = $CPPFLAGS $PACKAGE_CFLAGS (as set at the point in configure.ac)
+#     $6 = $LDFLAGS $PACKAGE_LDFLAGS (as set at the point in configure.ac)
+#
+#     PACKAGE_NAME defaults to $PACKAGE if not set.
+#     PACKAGE_LIBS defaults to -l$PACKAGE_NAME if not set.
+#
+#   The resulting file is called $PACKAGE.pc.in / $PACKAGE.pc
+#
+#   You will find this macro most useful in conjunction with
+#   ax_spec_defaults that can read good initializers from the .spec file. In
+#   consequencd, most of the generatable installable stuff can be made from
+#   information being updated in a single place for the whole project.

+# SYNOPSIS
+#
+#   AX_CREATE_STDINT_H [( HEADER-TO-GENERATE [, HEDERS-TO-CHECK])]
+#
+# DESCRIPTION
+#
+#   the "ISO C9X: 7.18 Integer types <stdint.h>" section requires the
+#   existence of an include file <stdint.h> that defines a set of typedefs,
+#   especially uint8_t,int32_t,uintptr_t. Many older installations will not
+#   provide this file, but some will have the very same definitions in
+#   <inttypes.h>. In other enviroments we can use the inet-types in
+#   <sys/types.h> which would define the typedefs int8_t and u_int8_t
+#   respectivly.
+#
+#   This macros will create a local "_stdint.h" or the headerfile given as
+#   an argument. In many cases that file will just "#include <stdint.h>" or
+#   "#include <inttypes.h>", while in other environments it will provide the
+#   set of basic 'stdint's definitions/typedefs:
+#
+#     int8_t,uint8_t,int16_t,uint16_t,int32_t,uint32_t,intptr_t,uintptr_t
+#     int_least32_t.. int_fast32_t.. intmax_t
+#
+#   which may or may not rely on the definitions of other files, or using
+#   the AC_CHECK_SIZEOF macro to determine the actual sizeof each type.
+#
+#   if your header files require the stdint-types you will want to create an
+#   installable file mylib-int.h that all your other installable header may
+#   include. So if you have a library package named "mylib", just use
+#
+#        AX_CREATE_STDINT_H(mylib-int.h)
+#
+#   in configure.ac and go to install that very header file in Makefile.am
+#   along with the other headers (mylib.h) - and the mylib-specific headers
+#   can simply use "#include <mylib-int.h>" to obtain the stdint-types.
+#
+#   Remember, if the system already had a valid <stdint.h>, the generated
+#   file will include it directly. No need for fuzzy HAVE_STDINT_H things...
+#   (oops, GCC 4.2.x has deliberatly disabled its stdint.h for non-c99
+#   compilation and the c99-mode is not the default. Therefore this macro
+#   will not use the compiler's stdint.h - please complain to the GCC
+#   developers).

+# SYNOPSIS
+#
+#   AX_GCC_ARCHFLAG([PORTABLE?], [ACTION-SUCCESS], [ACTION-FAILURE])
+#
+# DESCRIPTION
+#
+#   This macro tries to guess the "native" arch corresponding to the target
+#   architecture for use with gcc's -march=arch or -mtune=arch flags. If
+#   found, the cache variable $ax_cv_gcc_archflag is set to this flag and
+#   ACTION-SUCCESS is executed; otherwise $ax_cv_gcc_archflag is is set to
+#   "unknown" and ACTION-FAILURE is executed. The default ACTION-SUCCESS is
+#   to add $ax_cv_gcc_archflag to the end of $CFLAGS.
+#
+#   PORTABLE? should be either [yes] (default) or [no]. In the former case,
+#   the flag is set to -mtune (or equivalent) so that the architecture is
+#   only used for tuning, but the instruction set used is still portable. In
+#   the latter case, the flag is set to -march (or equivalent) so that
+#   architecture-specific instructions are enabled.
+#
+#   The user can specify --with-gcc-arch=<arch> in order to override the
+#   macro's choice of architecture, or --without-gcc-arch to disable this.
+#
+#   When cross-compiling, or if $CC is not gcc, then ACTION-FAILURE is
+#   called unless the user specified --with-gcc-arch manually.
+#
+#   Requires macros: AX_CHECK_COMPILER_FLAGS, AX_GCC_X86_CPUID
+#
+#   (The main emphasis here is on recent CPUs, on the principle that doing
+#   high-performance computing on old hardware is uncommon.)

+# SYNOPSIS
+#
+#   AX_GCC_X86_CPUID(OP)
+#
+# DESCRIPTION
+#
+#   On Pentium and later x86 processors, with gcc or a compiler that has a
+#   compatible syntax for inline assembly instructions, run a small program
+#   that executes the cpuid instruction with input OP. This can be used to
+#   detect the CPU type.
+#
+#   On output, the values of the eax, ebx, ecx, and edx registers are stored
+#   as hexadecimal strings as "eax:ebx:ecx:edx" in the cache variable
+#   ax_cv_gcc_x86_cpuid_OP.
+#
+#   If the cpuid instruction fails (because you are running a
+#   cross-compiler, or because you are not using gcc, or because you are on
+#   a processor that doesn't have this instruction), ax_cv_gcc_x86_cpuid_OP
+#   is set to the string "unknown".
+#
+#   This macro mainly exists to be used in AX_GCC_ARCHFLAG.

+
+# serial 5 lt~obsolete.m4
+
+# These exist entirely to fool aclocal when bootstrapping libtool.
+#
+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)
+#
+# So we provide this file, which has a silly filename so it's always
+# included after everything else.  This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+# Yes, that means every name once taken will need to remain here until
+# we give up compatibility with versions before 1.7, at which point
+# we need to keep only those names which we still refer to.
+
+# This is to help aclocal find these macros, as it can't see m4_define.

+# ===========================================================================
+#
+# SYNOPSIS
+#
+#   AX_CC_MAXOPT
+#
+# DESCRIPTION
+#
+#   Try to turn on "good" C optimization flags for various compilers and
+#   architectures, for some definition of "good". (In our case, good for
+#   FFTW and hopefully for other scientific codes. Modify as needed.)
+#
+#   The user can override the flags by setting the CFLAGS environment
+#   variable. The user can also specify --enable-portable-binary in order to
+#   disable any optimization flags that might result in a binary that only
+#   runs on the host architecture.
+#
+#   Note also that the flags assume that ANSI C aliasing rules are followed
+#   by the code (e.g. for gcc's -fstrict-aliasing), and that floating-point
+#   computations can be re-ordered as needed.
+#
+#   Requires macros: AX_CHECK_COMPILER_FLAGS, AX_COMPILER_VENDOR,
+#   AX_GCC_ARCHFLAG, AX_GCC_X86_CPUID.

+# SYNOPSIS
+#
+#   AX_CFLAGS_WARN_ALL [(shellvar [,default, [A/NA]])]
+#
+# DESCRIPTION
+#
+#   Try to find a compiler option that enables most reasonable warnings.
+#
+#   For the GNU CC compiler it will be -Wall (and -ansi -pedantic) The
+#   result is added to the shellvar being CFLAGS by default.
+#
+#   Currently this macro knows about GCC, Solaris C compiler, Digital Unix C
+#   compiler, C for AIX Compiler, HP-UX C compiler, IRIX C compiler, NEC
+#   SX-5 (Super-UX 10) C compiler, and Cray J90 (Unicos 10.0.0.8) C
+#   compiler.
+#
+#    - $1 shell-variable-to-add-to : CFLAGS
+#    - $2 add-value-if-not-found : nothing
+#    - $3 action-if-found : add value to shellvariable
+#    - $4 action-if-not-found : nothing

+# SYNOPSIS
+#
+#   AX_GCC_ARCHFLAG([PORTABLE?], [ACTION-SUCCESS], [ACTION-FAILURE])
+#
+# DESCRIPTION
+#
+#   This macro tries to guess the "native" arch corresponding to the target
+#   architecture for use with gcc's -march=arch or -mtune=arch flags. If
+#   found, the cache variable $ax_cv_gcc_archflag is set to this flag and
+#   ACTION-SUCCESS is executed; otherwise $ax_cv_gcc_archflag is is set to
+#   "unknown" and ACTION-FAILURE is executed. The default ACTION-SUCCESS is
+#   to add $ax_cv_gcc_archflag to the end of $CFLAGS.
+#
+#   PORTABLE? should be either [yes] (default) or [no]. In the former case,
+#   the flag is set to -mtune (or equivalent) so that the architecture is
+#   only used for tuning, but the instruction set used is still portable. In
+#   the latter case, the flag is set to -march (or equivalent) so that
+#   architecture-specific instructions are enabled.
+#
+#   The user can specify --with-gcc-arch=<arch> in order to override the
+#   macro's choice of architecture, or --without-gcc-arch to disable this.
+#
+#   When cross-compiling, or if $CC is not gcc, then ACTION-FAILURE is
+#   called unless the user specified --with-gcc-arch manually.
+#
+#   Requires macros: AX_CHECK_COMPILER_FLAGS, AX_GCC_X86_CPUID
+#
+#   (The main emphasis here is on recent CPUs, on the principle that doing
+#   high-performance computing on old hardware is uncommon.)

+#
+#   AX_GCC_X86_CPUID(OP)
+#
+# DESCRIPTION
+#
+#   On Pentium and later x86 processors, with gcc or a compiler that has a
+#   compatible syntax for inline assembly instructions, run a small program
+#   that executes the cpuid instruction with input OP. This can be used to
+#   detect the CPU type.
+#
+#   On output, the values of the eax, ebx, ecx, and edx registers are stored
+#   as hexadecimal strings as "eax:ebx:ecx:edx" in the cache variable
+#   ax_cv_gcc_x86_cpuid_OP.
+#
+#   If the cpuid instruction fails (because you are running a
+#   cross-compiler, or because you are not using gcc, or because you are on
+#   a processor that doesn't have this instruction), ax_cv_gcc_x86_cpuid_OP
+#   is set to the string "unknown".

+	contains only the functions related to the .scop format, and the
+	main scop/statement/matrix/vector functions.
+

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a
+# configured tree to be moved without reconfiguration.

+# Configuration subroutine to validate and canonicalize a configuration type.

+# or in some cases, the newer four-part form:
+#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM

+% a Texinfo source document, you may use the result without
+% restriction.  (This has been our intent since Texinfo was invented.)
+%
+% Please try the latest version of texinfo.tex before submitting bug
+% reports; you can get the latest version from:
+%   http://www.gnu.org/software/texinfo/ (the Texinfo home page), or
+%   ftp://tug.org/tex/texinfo.tex
+%     (and all CTAN mirrors, see http://www.ctan.org).
+% The texinfo.tex in any given distribution could well be out
+% of date, so if that's what you're using, please check.
+%
+% Send bug reports to bug-texinfo@gnu.org.  Please include including a
+% complete document in each bug report with which we can reproduce the
+% problem.  Patches are, of course, greatly appreciated.
+%
+% To process a Texinfo manual with TeX, it's most reliable to use the
+% texi2dvi shell script that comes with the distribution.  For a simple
+% manual foo.texi, however, you can get away with this:
+%   tex foo.texi
+%   texindex foo.??
+%   tex foo.texi
+%   tex foo.texi
+%   dvips foo.dvi -o  # or whatever; this makes foo.ps.
+% The extra TeX runs get the cross-reference information correct.
+% Sometimes one run after texindex suffices, and sometimes you need more
+% than two; texi2dvi does it as many times as necessary.
+%
+% It is possible to adapt texinfo.tex for other languages, to some
+% extent.  You can get the existing language-specific files from the
+% full Texinfo distribution.

+% PDF uses PostScript string constants for the names of xref targets,
+% for display in the outlines, and in other places.  Thus, we have to
+% double any backslashes.  Otherwise, a name like "\node" will be
+% interpreted as a newline (\n), followed by o, d, e.  Not good.
+% 
+% See http://www.ntg.nl/pipermail/ntg-pdftex/2004-July/000654.html and
+% related messages.  The final outcome is that it is up to the TeX user
+% to double the backslashes and otherwise make the string valid, so
+% that's what we do.  pdftex 1.30.0 (ca.2005) introduced a primitive to
+% do this reliably, so we use it.
+
+% #1 is a control sequence in which to do the replacements,
+% which we \xdef.

+% @multitable macros
+% Amy Hendrickson, 8/18/94, 3/6/96
+%
+% @multitable ... @end multitable will make as many columns as desired.
+% Contents of each column will wrap at width given in preamble.  Width
+% can be specified either with sample text given in a template line,
+% or in percent of \hsize, the current width of text on page.
+
+% Table can continue over pages but will only break between lines.
+
+% To make preamble:
+%
+% Either define widths of columns in terms of percent of \hsize:
+%   @multitable @columnfractions .25 .3 .45
+%   @item ...
+%
+%   Numbers following @columnfractions are the percent of the total
+%   current hsize to be used for each column. You may use as many
+%   columns as desired.
+
+
+% Or use a template:
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item ...
+%   using the widest term desired in each column.
+
+% Each new table line starts with @item, each subsequent new column
+% starts with @tab. Empty columns may be produced by supplying @tab's
+% with nothing between them for as many times as empty columns are needed,
+% ie, @tab@tab@tab will produce two empty columns.
+
+% @item, @tab do not need to be on their own lines, but it will not hurt
+% if they are.
+
+% Sample multitable:
+
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item first col stuff @tab second col stuff @tab third col
+%   @item
+%   first col stuff
+%   @tab
+%   second col stuff
+%   @tab
+%   third col
+%   @item first col stuff @tab second col stuff
+%   @tab Many paragraphs of text may be used in any column.
+%
+%         They will wrap at the width determined by the template.
+%   @item@tab@tab This will be in third column.
+%   @end multitable
+
+% Default dimensions may be reset by user.
+% @multitableparskip is vertical space between paragraphs in table.
+% @multitableparindent is paragraph indent in table.
+% @multitablecolmargin is horizontal space to be left between columns.
+% @multitablelinespace is space to leave between table items, baseline
+%                                                            to baseline.

+\`configure' configures osl 0.8.3 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          @<:@@S|@ac_default_prefix@:>@
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          @<:@PREFIX@:>@
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+                          Exec prefix of gmp installation
+  --with-gmp-builddir=DIR Location of gmp builddir
+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+\`configure' configures osl 0.8.3 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX

+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          @<:@PREFIX@:>@
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help

+\`configure' configures osl 0.8.3 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          @<:@@S|@ac_default_prefix@:>@
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          @<:@PREFIX@:>@
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:

+  --with-sysroot=DIR Search for dependent libraries within DIR
+                        (or the compiler's sysroot if not specified).

+                          Exec prefix of gmp installation
+  --with-gmp-builddir=DIR Location of gmp builddir
+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+@node Introduction
+@chapter Introduction
+OpenScop is an open specification that defines a file format and a set of
+data structures to represent a @emph{static control part} (SCoP for short),
+i.e., a program part that can be represented in the @emph{polyhedral model}.
+The goal of OpenScop is to provide a common interface to various
+polyhedral compilation tools in order to simplify their interaction. 
+
+Designing a single format for tools that have different purposes
+(e.g., as different as code generation and data dependence analysis) may
+sound strange at first. However we could observe that most available
+polyhedral compilation tools during the last decade were manipulating
+more or less the same kind of data (polyhedra, affine functions...) and
+were actually sharing a part of their input (e.g., iteration domains and
+context concepts are nearly everywhere). We could also observe that
+those tools may rely on different internal representations, mostly based on
+one of the major polyhedral libraries (e.g., Polylib, PPL or isl), and
+this representation may change over time (e.g., when switching to a
+more convenient polyhedral library).
+The OpenScop aim is to provide a stable, unified format that offers a
+durable guarantee that a tool can use an output or provide an input to
+another tool without breaking a tool chain because of some internal
+changes in one element of the chain. The other promise of OpenScop is
+the ability to assemble or replace the basic blocks of a polyhedral
+compilation framework at no, or at least low engineering cost.
+
+The policy that drives OpenScop can be summarized by these three rules:
+@itemize @bullet
+@item  Embed the @emph{minimum} information to build a complete polyhedral
+       compilation framework in the so-called @emph{core part}
+       (to avoid as much as possible empty or useless information
+       for each tool).
+@item  Provide a @emph{very stable} core part (so users have some
+       guarantee that they will not need to update their tool
+       because of frequent specification evolution),
+@item  Provide a @emph{very flexible} extension part (so it can also
+       be used to test wild new ideas).
+@end itemize
+
+@noindent Another, more technical, rule may be added:
+@itemize @bullet
+@item  Avoid any need for external library or tool to support it
+       (i.e., it's not XML or YAML or anything like that).
+@end itemize
+
+The success of OpenScop in meeting its goals totally depends on its
+acceptance by the tool developers (that have to support it in their tools).
+To help them, we provide an example implementation: the OpenScop Library.
+This library (and in particular its API) is not part of the OpenScop
+specification (which includes only the file format and the set of data
+structures). It is licensed under the 3-clause BSD license so developers may
+feel free to use it in their code (either by linking it or copy-pasting its
+code). This document also describes this library briefly (readers are
+invited to read at its technical documentation).
+The current version of the OpenScop Library is still under evaluation,
+and there is no guarantee that the upward compatibility will be respected,
+even if we do think so. A lot of reports are
+necessary to freeze the library API. Thus you are very welcome and
+encouraged to send reports on bugs, wishes, critics, comments, suggestions
+or (please!) successful experiences to the OpenScop mailing list
+@email{openscop-development@@googlegroups.com}.
+
+This document is organized as follows. First, we provide some
+background on the polyhedral model and how it is used to represent and to
+manipulate programs (@pxref{Polyhedral Representation}). Next,
+we describe the OpenScop specification, from the file format
+(@pxref{OpenScop File Format Specification}) to the data structures
+and the OpenScop Library API
+(@pxref{OpenScop Data Structure Specification}).
+Finally we will detail how to install the OpenScop Library
+(@pxref{Installation}).

+@chapter Polyhedral Representation of Programs
+If you are reading at the OpenScop documentation, you probably don't need any
+explanation about the polyhedral model. It is unlikely that someone will read
+this paper by mistake. However some vicious advisor may ask their poor
+engineers/interns/students
+to work for the very first time on this exciting topic. Most papers on
+polyhedral compilation are hard to read. Despite my efforts,
+mine are no exception according to some reviewers. Hence I give there a new
+try to provide a comprehensive explanation of the polyhedral model without the
+size and style limits of a classical research paper.
+
+Be aware that to be able to understand the polyhedral model, there are a few
+prerequisites. You should not read the following while you still ignore
+what is:
+@itemize @bullet
+@item  a @code{for} loop construction in C programs (@code{do} loops in FORTRAN are OK too!),
+@item  an @emph{affine expression},
+@item  a @emph{vector},
+@item  a @emph{matrix},
+@item  a @emph{matrix-vector multiply}.
+@end itemize
+If you do not know those concepts, please do some search and come back
+afterwards. And if you are courageous enough, send me a few lines that
+describe them so I can insert them here!

+@node Motivation
+@section Motivation: Program Transformations
+
+A direct translation of high level programs written, e.g., in C, to assembly
+then to object code is likely to produce (very) inefficient applications.
+Architectures are
+quite complex, including several levels of cache memory, many cores, deep
+pipelines, various number of functional units, of registers etc.
+The list of such
+"architectural features" is growing with each new generation of processors.
+To achieve the best performance, the object program must use
+these features in a smart way.
+Programmers use high level languages for productivity and portability:
+typically they do not have to take care of the target architecture but
+to ensure they write programs which produce the right output. Hence,
+the problem of mapping the program to the target architecture in the most
+efficient way is left to the compiler.
+
+The compiler may see a high level program as a specification
+@emph{of an output}. The program is a list of instructions to be executed to
+produce the output. As long as the output is guaranteed to be as the
+programmer specified in his code, the compiler is free to modify
+the program.
+For instance, let us imagine we are working on an architecture with only
+three registers and we consider the following statements written by
+a programmer:
+
+@example
+@group
+x = a + b;
+y = c + d;
+z = a * b;
+@end group
+@end example
+
+It is easy to see that we can reorder the three statements in any way without
+modifying the semantics (no statement reads or writes a variable that another
+statement writes). Because of the lack of registers, the solutions such that
+the first and the third statements are one after the other are better
+because @code{a} and @code{b} will be put in the processor registers by
+one statement and can be reused directly by the other one
+without reading from memory (this is called a @emph{data locality
+improving} transformation). Hence a better statement order is, e.g.:
+
+@example
+@group
+x = a + b;
+z = a * b; // a and b are still in processor registers
+y = c + d;
+@end group
+@end example
+
+We can also notice that it is possible to run the three statements in
+parallel (possibly on different processors). The programmer may
+explicit this in a way the compiler
+and/or the architecture is able to understand. For instance,
+we can use OpenMP to describe parallelism
+(this is called a @emph{parallelizing} transformation):
+
+@example
+@group
+#pragma omp parallel sections
+@{
+   #pragma omp section
+   @{
+     x = a + b;
+   @}
+   #pragma omp section
+   @{
+     y = c + d;
+   @}
+   #pragma omp section
+   @{
+     z = a * b;
+   @}
+@}
+@end group
+@end example
+
+However, the right way to optimize this program is probably a tradeoff
+between these two techniques. This is true if, e.g., the target
+architecture has some limitations to run too many operations in parallel,
+or, like in our case, when some data may be reused by some processors.
+Hence, the best optimization for our small example is probably the
+following:
+
+@example
+@group
+#pragma omp parallel sections
+@{
+   #pragma omp section
+   @{
+     x = a + b;
+     z = a * b;
+   @}
+   #pragma omp section
+   @{
+     y = c + d;
+   @}
+@}
+@end group
+@end example
+
+This example is quite trivial because the statements are
+executed only once. The real sport begins when we have to deal with loops,
+as we will see momentarily. However, polyhedral compilation framework users
+have to be conscious that we @emph{need} to transform programs to achieve
+the best performance and that the best transformation  that has to be
+discovered (at the price of many, many efforts) and performed may be
+quite complex. Hence the need of powerful model and tools.
+
+
+@node Thinking in Polyhedra
+@section Thinking in Polyhedra
+
+
+Since the very first compilers, the internal representation of programs
+is the @emph{Abstract Syntax Tree}, or AST. In such representation,
+each statement appears only once even if it is executed many times (e.g.,
+when it is enclosed inside a loop). This is a limitation
+for finding and applying complex transformations:
+@itemize @bullet
+@item It limits program analysis power. For instance if a statement
+      @emph{depends} on another statement (i.e., they access the same
+      memory location and at least one of these accesses is a write),
+      we will consider both statements as unique entities while the
+      dependence relation may involve only few statement executions.
+@item It limits program transformation power. Loop transformations
+      operate on statement executions. For instance, because they
+      consider all statement executions at the same time, present day
+      production compilers are not able to achieve loop fusion
+      (that tries to merge the loop bodies of two loops) if the loop bounds
+      of the two loops do not match (yes, that's ridiculous).
+@item It limits program manipulation flexibility.
+      Trees are very rigid data structures that are not easy to manipulate.
+      Program transformation may require very complex transformations that will
+      imply deep modifications of the control flow.
+@end itemize
+
+The Polyhedral Model is a convenient alternative representation which
+combines analysis power, expressiveness and high flexibility. The drawback
+is it breaks the classical structure of programs that every programmer
+is familiar with. It requires some (real) efforts
+to be smoothly manipulated, but it definitely worth it. It is based on three
+main concepts, @emph{iteration domain},  @emph{scattering function} and
+@emph{access function} that are described in depth in the
+following sections.
+
+A program part that can be represented using the Polyhedral Model is called
+a @strong{Static Control Part} or @strong{SCoP} for short.
+
+@menu

+@end menu
+
+@node Iteration Domain
+@subsection Iteration Domain
+
+The key aspect of the polyhedral model is to consider @emph{statement
+instances}. A statement instance is @emph{one} execution of a statement.
+A statement
+outside a loop has only one instance while those inside loops may have many.
+Let us consider the following code with two statements @code{S1}
+and @code{S2}:
+
+@example
+@group
+pi = 3.14;               // S1
+for (i = 0; i < 5; i++)
+  A[i] = pi;             // S2
+@end group
+@end example
+
+The list of statement instances is the following (we just have to fully
+unroll the loop):
+
+@example
+@group
+pi = 3.14;
+A[0] = pi;
+A[1] = pi;
+A[2] = pi;
+A[3] = pi;
+A[4] = pi;
+@end group
+@end example
+
+Each instance of a statement which is enclosed inside a loop may be referred
+thanks to its outer loop counters (or @emph{iterators}). In the polyhedral
+model we consider statements as functions of the outer loop counters that may
+produce statement instances:
+instead of simply "@code{S2}", we use preferably the notation @code{S2(i)}.
+For instance we  denote the statement instance @code{A[3] = pi;} of the
+previous example as @code{S2(3)}. This means @emph{instance of
+statement @code{S2} for} @code{i = 3}.
+If a statement @code{S3} is enclosed inside two loops of iterators @code{i}
+(outermost loop) and @code{j} (innermost loop), we would denote it
+@code{S3(i,j)}, and so on with more enclosing loops.
+
+The ordered list
+of iterators (ordered from the outermost iterator to the innermost iterator)
+is called the @strong{iteration vector}. For instance the iteration vector for
+@code{S3} is @code{(i,j)}, for @code{S2} it is @code{(i)}, and for @code{S1}
+it is empty since it has no enclosing loop: @code{()}. A more precise reading
+at the notation @code{S2(3)} would show that it denotes the instance of
+statement @code{S2} for the iteration vector @code{(2)}.
+
+Obviously, dealing with statement instances does not mean we have to unroll all
+loops. First because there would be probably too many instances to deal with,
+and second because we probably just do not know how many instances there are.
+For instance in the following loop it is impossible to know (at compile time)
+how many times the statement @code{S3} will be executed:
+
+@example
+@group
+for (i = 2; i <= N; i++)
+  for (j = 2; j <= N; j++)
+    A[i] = pi;             // S3
+@end group
+@end example
+
+@noindent Such a loop is said to be @emph{parametric}: it depends on
+(at least) a value called a @emph{parameter} which is not modified
+during the execution of the whole loop, but is unknown at compile time.
+Here, the only parameter is @code{N}.
+
+A compact way to represent all the instances of a given statement
+is to consider the set of all possible values of its iteration vector.
+This set is called the @strong{iteration domain}. It can be conveniently
+described thanks to all the constraints on the various iterators the statement
+depends on. For instance, let us consider
+the statement @code{S3} of the previous program. The iteration domain is the set
+of iteration vectors @code{(i,j)}. Because of the parameter, we are not able to
+achieve a precise list of all possible values. It would look like this:
+
+@example
+@group
+(2,2)  (2,3)  (2,4)  ...  (2,N)
+(3,2)  (3,3)  (3,4)  ...  (3,N)
+...    ...    ...    ...  ...
+(N,2)  (N,3)  (N,4)  ...  (N,N)
+@end group
+@end example
+
+@noindent A better way is to say it is the set
+of iteration vectors @code{(i,j)} such that @code{i} is an integer greater or
+equal than 2 and lower or equal than @code{N}, and @code{j} is an integer
+greater or equal than 2 and lower or equal than @code{N}. This may be written
+in the following mathematical form:
+
+@tex
+$$D _{S3} =  \{(i,j) \in Z^2 \; | \; 2 \leq i \leq N \land 2 \leq j \leq N \}$$
+@end tex
+
+@ifnottex
+@example
+@group
+D_S3 =  @{(i,j) in Z^2 | 2 <= i <= N && 2 <= j <= N @}
+@end group
+@end example
+@end ifnottex
+
+@noindent It is easy to see that this iteration domain is a part of the
+2-dimensional space
+@tex
+$Z^2$.
+@end tex
+@ifnottex
+@example
+@group
+Z^2.
+@end group
+@end example
+@end ifnottex
+We often use in our research papers a graphical representation that gives a
+better view of this subspace:
+
+@image{images/basic1,4cm}
+
+@noindent Here, the iteration domain is specified thanks to a set of
+constraints. When those constraints are affine and
+depend only on the outer loop counters and some parameters, the set of
+constraints defines a @emph{polyhedron} (more precisely this is a
+@emph{Z-polyhedron}, but we use @emph{polyhedron} for short).
+Hence the @emph{polyhedral model}!
+
+To manipulate a set of affine constraints easily, we rely on a matrix
+representation. To write it, we use the @emph{homogeneous} iteration vector:
+it is simply the iteration vector with some additional dimensions to
+represent the parameters and the constant.
+For instance for the statement @code{S3}, the
+iteration vector in homogeneous coordinates is @code{(i, j, N, 1)}
+(we will now call it @emph{iteration vector} directly for short).
+Then we write all the constraints as affine inequalities of the form
+@emph{affine constraint}
+@tex
+$\geq 0$.
+@end tex
+@ifnottex
+@code{ >= 0}.
+@end ifnottex
+For instance for the statement @code{S3} the set of constraints is:
+
+@tex
+$$
+\hbox{$ \cases{  i         - 2  &$\geq 0$\cr
+                -i     + N      &$\geq 0$\cr
+                     j     - 2  &$\geq 0$\cr
+                    -j + N      &$\geq 0$}$}
+$$
+@end tex
+
+@ifnottex
+@example
+@group
+    i - 2 >= 0
+   -i + N >= 0
+    j - 2 >= 0
+   -j + N >= 0
+@end group
+@end example
+@end ifnottex
+
+@noindent Lastly, we translate the constraint system to the form
+@strong{domain matrix}@code{ * }@emph{iteration vector}@code{ >= 0}:

+information on the iteration domain of a given statement (the iteration vector
+is in general an implicit information).}
+
+@node Scattering Function
+@subsection Scattering Function
+
+There is no ordering information inside the iteration domain: it only describes
+the set of statement instances but @strong{not} the order in which they have
+to be executed relatively to each other. In the past the lexicographic order
+of the iteration domain was considered, this is no more true
+(especially when using CLooG). If we do not provide any ordering information, this
+means that the statement instances may be executed in any order
+(this is useful, e.g., to specify parallelism). However, some statement instances
+may depend on some others and it may be critical to enforce a given order (or
+non-order). Hence we need another information.
+
+We call @emph{scattering} any kind of ordering information in the polyhedral
+model. There exists many kind of ordering, such as @emph{allocation},
+@emph{scheduling}, @emph{chunking} etc. They are all expressed
+in the same way, i.e., using @emph{logical stamps}, but they may have
+different semantics.
+
+In the case of @strong{scheduling}, the logical stamps are logical dates that
+express at which date a statement instance has to be executed. For instance,
+let us consider the following three statements:
+
+@example
+@group
+x = a + b;   // S1
+y = c + d;   // S2
+z = a * b;   // S3
+@end group
+@end example
+
+@noindent The scheduling of a statement @code{S} is typically
+denoted by
+@tex
+$\theta_{S}$.
+@end tex
+@ifnottex
+T_S.
+@end ifnottex
+Let us consider the following logical dates for each statement:
+
+@tex
+@example
+@group
+$\theta_{S1} = 2$
+$\theta_{S2} = 3$
+$\theta_{S3} = 1$
+@end group
+@end example
+@end tex
+
+@ifnottex
+@example
+@group
+T_S1 = 1
+T_S2 = 2
+T_S3 = 3
+@end group
+@end example
+@end ifnottex
+
+@noindent It means that statement @code{S3} has to be executed at logical date
+@code{1}, statement @code{S1} has to be executed at logical date
+@code{2} and statement @code{S2} has to be executed at logical date
+@code{3}. The target code has to respect this scheduling (the order of
+the logical dates), hence it would look like the following where the
+variable @code{t} denotes the time:
+
+@example
+@group
+t = 1;
+z = a * b;   // S3
+t = 2;
+x = a + b;   // S1
+t = 3;
+y = c + d;   // S2
+@end group
+@end example
+
+@noindent When some statements share the same logical date, this means that,
+once the program reaches this logical date, the two statements can be executed
+in any order, or better, in parallel. For instance let us consider the
+following scheduling:
+
+@tex
+@example
+@group
+$\theta_{S1} = 1$
+$\theta_{S2} = 2$
+$\theta_{S3} = 1$
+@end group
+@end example
+@end tex
+
+@ifnottex
+@example
+@group
+T_S1 = 1
+T_S2 = 2
+T_S3 = 1
+@end group
+@end example
+@end ifnottex
+
+@noindent Statements @code{S1} and @code{S3} have the same logical date,
+moreover, @code{S2} has a greater logical date than @code{S1} and @code{S3}.
+Hence the target code would be:
+
+@example
+@group
+t = 1;
+#pragma omp parallel sections
+@{
+   #pragma omp section
+   @{
+     x = a + b;   // S1
+   @}
+   #pragma omp section
+   @{
+     z = a * b;   // S3
+   @}
+@}
+t = 2;
+y = c + d;        // S2
+@end group
+@end example
+
+Logical dates may be multidimensional, as clocks: the first dimension
+may correspond to days (most significant), the next one to hours (less
+significant), the third to minutes and so on. For instance we can consider
+the following multidimensional schedules for our example:
+
+@tex
+@example
+@group
+$\theta_{S1} = (1,1)$
+$\theta_{S2} = (2,1)$
+$\theta_{S3} = (1,2)$
+@end group
+@end example
+@end tex
+
+@ifnottex
+@example
+@group
+T_S1 = (1,1)
+T_S2 = (2,1)
+T_S3 = (1,2)
+@end group
+@end example
+@end ifnottex
+
+@noindent It is not very hard to decypher the meaning of such scheduling.
+Because of the first dimension, statements @code{S1} and @code{S3} will be
+executed before statement @code{S2} (@code{S1} and @code{S3} are executed at
+day 1, while @code{S2} is executed at day 2). The second dimension is not
+really useful there for @code{S2} because it is the only statement executed
+at day 2. Nevertheless it allows to order @code{S1} and
+@code{S3} relatively to each other since @code{S1} is executed at hour 1 of day
+1 while @code{S3} is executed at hour 2 of day 1.
+The corresponding target code is the following, with some
+additional time variables for a better view of the ordering (@code{t1}
+corresponds to the first time dimension, @code{t2} to the second one):
+
+@example
+@group
+t1 = 1;
+t2 = 1;
+x = a + b;   // S1
+t2 = 2;
+z = a * b;   // S3
+t1 = 2;
+t2 = 1;
+y = c + d;   // S2
+@end group
+@end example
+
+In the case of @strong{allocation} (in the literature we can find some
+papers calling it @emph{placement}), the logical stamp is a processor
+number expressing on which processor a statement instance has to be
+executed. Typically, allocations are written in the same way as scheduling.
+Here, we denote it @math{P_S} for a statement @code{S}.
+For instance, let us consider the following allocation:
+
+@tex
+@example
+@group
+$P_{S1} = 1$
+$P_{S2} = 2$
+$P_{S3} = 1$
+@end group
+@end example
+@end tex
+
+@ifnottex
+@example
+@group
+P_S1 = 1
+P_S2 = 2
+P_S3 = 1
+@end group
+@end example
+@end ifnottex
+
+@noindent The corresponding target code has to take into account that both
+statements @code{S1} and @code{S3} have to be executed on the same processor
+(they have the same logical number 1) and that statement @code{S2} has
+to be executed on another processor (logical number 2). A possible target code
+is the following:
+
+@example
+@group
+#pragma omp parallel sections
+@{
+   #pragma omp section
+   @{
+     // Logical processor 1
+     x = a + b;   // S1
+     z = a * b;   // S3
+   @}
+   #pragma omp section
+   @{
+     // Logical processor 2
+     y = c + d;   // S2
+   @}
+@}
+@end group
+@end example
+
+@noindent We can note that no order has been specified for the
+statements @code{S1} and @code{S3} that are executed on the same processor.
+Hence any order is satisfying. For sake of flexibility, it is usual to build
+a scattering whose various dimensions do not have the same semantics. A
+typical construction is @emph{space/time mapping} where the first @code{n}
+dimensions are devoted to allocation, then the last @code{m}
+dimensions are devoted to scheduling. Typically, space/time mapping is
+written in the same way as scheduling.
+Here we denote it @math{M_S} for a statement @code{S}.
+For instance, let us consider the following space/time mapping for our
+example where one dimension is devoted to mapping and one dimension is
+devoted to scheduling:
+
+@tex
+@example
+@group
+$M_{S1} = (1,2)$
+$M_{S2} = (2,1)$
+$M_{S3} = (1,1)$
+@end group
+@end example
+@end tex
+
+@ifnottex
+@example
+@group
+M_S1 = (1,2)
+M_S2 = (2,1)
+M_S3 = (1,1)
+@end group
+@end example
+@end ifnottex
+
+@noindent Here we have the same first dimension as the previous example, thus
+the allocation of the statements to processors is the same. The second
+dimension precises on a given processor at which logical date a statement
+instance has to be executed. Here, the statement @code{S1} is executed at
+day 2 on processor 1 while the statement @code{S3} is executed at day 1 onto
+the same processor. It follows this space/time mapping corresponds to the
+following target code (we added an additional variable to represent the
+local logical clocks):
+
+@example
+@group
+#pragma omp parallel sections
+@{
+   #pragma omp section
+   @{
+     // Logical processor 1
+     t = 1;
+     z = a * b;   // S3
+     t = 2;
+     x = a + b;   // S1
+   @}
+   #pragma omp section
+   @{
+     // Logical processor 2
+     t = 1;
+     y = c + d;   // S2
+   @}
+@}
+@end group
+@end example
+
+For the same reason as discussed for iteration domains
+(@pxref{Iteration Domain}), it is not possible to define a scattering for
+each statement instance, especially if the statement belongs to a
+(possibly parametric) loop. The iteration vector fully defines an
+instance of a given statement. Thus, a practical way to provide a scattering
+for each instance of a given statement is to use a @emph{function}
+that depends on the iteration vector. In this way the function may associate
+to each iteration vector a different scattering. We call these functions
+@strong{scattering functions}. Scattering functions are @emph{affine}
+functions of the outer loop counter and the global parameters.
+For instance, let us consider the following source code:
+
+@example
+@group
+for (i = 2; i <= 4; i++)
+  for (j = 2; j <= 4; j++)
+    P[i+j] += A[i] + B[j]; // S4
+@end group
+@end example
+
+@noindent The iteration domain of the statement @code{S4} is:
+
+
+@tex
+$$D _{S4} =  \{(i,j) \in Z^2 \; | \; 2 \leq i \leq 4 \land 2 \leq j \leq 4 \}.$$
+@end tex
+@ifnottex
+@example
+@group
+D_S4=  @{(i,j) in Z^2 | 2 <= i <= 4 && 2 <= j <= 4 @}.
+@end group
+@end example
+@end ifnottex
+
+@noindent If you are still not comfortable with the mathematical notation, it
+corresponds to the following graphical representation:
+
+@image{images/basic2,3cm}
+
+@noindent The list of the statement instances of @code{S4} (the integer
+points of its iteration domain) corresponds to the following iteration vectors:
+
+@example
+@group
+iteration vector
+     (2,2)
+     (2,3)
+     (2,4)
+     (3,2)
+     (3,3)
+     (3,4)
+     (4,2)
+     (4,3)
+     (4,4)
+@end group
+@end example
+
+@noindent Let us suppose we want to schedule the instances of the statement
+@code{S4} (the integer points of its iteration domain) using the following
+scheduling function:
+
+@tex
+@example
+@group
+$\theta_{S4}(i, j) = (j+2, 3*i+j)$
+@end group
+@end example
+@end tex
+
+@ifnottex
+@example
+@group
+T_S4(i,j) = (j+2,3*i+j)
+@end group
+@end example
+@end ifnottex
+
+@noindent We only need to apply the function to each iteration vector to find
+the logical date of each instance:
+
+@example
+@group
+iteration vector       logical date
+     (2,2)       -->       (4,8)
+     (2,3)       -->       (5,9)
+     (2,4)       -->       (6,10)
+     (3,2)       -->       (4,11)
+     (3,3)       -->       (5,12)
+     (3,4)       -->       (6,13)
+     (4,2)       -->       (4,14)
+     (4,3)       -->       (5,15)
+     (4,4)       -->       (6,16)
+@end group
+@end example
+
+The polyhedral model users do not have to take care about the generation of a
+target code that respects the scattering: the
+CLooG@footnote{@url{http://www.cloog.org}} tool is there to
+solve the problem quite easily. For the previous
+example, the target code would be the following (@code{t1} and @code{t2}
+correspond to the two dimensions of the logical date, the reader may
+take care that this code actually implements the scattering function):
+
+@example
+@group
+for (t1 = 4; t1 <= 6; t1++) @{
+  for (t2 = t1+4; t2 <= t1+10; t2++) @{
+    if ((-t1+t2+2)%3 == 0) @{
+      i = (-t1+t2+2)/3 ;
+      j = t1-2 ;
+      P[i+j] += A[i] + B[j]; // S4
+    @}
+  @}
+@}
+@end group
+@end example
+
+
+
+Obviously with such a twisted scheduling, it is hard to see the "meaning"
+of the transformation. To name any kind of program transformation as
+a magic spell ("tile", "fuse", "skew"...) is an old bad habit which is not
+relevant anymore in the polyhedral model: a scheduling may be an arbitrary
+complex sequence of basic-old-good transformations. Nevertheless it is most
+of the time quite easy to translate well known transformations to schedules.
+For instance, let us consider this new scheduling function:
+
+@tex
+@example
+@group
+$\theta_{S4}(i,j) = (j,i)$
+@end group
+@end example
+@end tex
+
+@ifnottex
+@example
+@group
+T_S4(i,j) = (j,i)
+@end group
+@end example
+@end ifnottex
+
+@noindent Using CLooG, we can generate the target code:
+
+@example
+@group
+for (t1 = 2; t1 <= 4; t1++) @{
+  for (t2 = 2; t2 <= 4; t2++) @{
+    i = t2;
+    j = t1;
+    P[i+j] += A[i] + B[j]; // S4
+  @}
+@}
+@end group
+@end example
+
+
+@noindent It is easy to see (and analyze) that it corresponds to a classical
+@emph{loop interchange} transformation.
+
+A very useful example of multi-dimensional scattering functions is
+the @strong{scheduling of the original program}.
+The method to compute it is quite simple (@pxref{Fea92}). The idea is to
+build an abstract syntax tree of the program and to read the scheduling for
+each statement. For instance, let us consider the following implementation of
+a Cholesky factorization:
+
+@example
+@group
+/* A Cholesky factorization kernel. */
+for (i=1;i<=N;i++) @{
+  for (j=1;j<=i-1;j++) @{
+    a[i][i] -= a[i][j] ;           // S1
+  @}
+  a[i][i] = sqrt(a[i][i]) ;        // S2
+  for (j=i+1;j<=N;j++) @{
+    for (k=1;k<=i-1;k++) @{
+      a[j][i] -= a[j][k]*a[i][k] ; // S3
+    @}
+    a[j][i] /= a[i][i] ;           // S4
+    @}
+  @}
+@}
+@end group
+@end example
+
+@noindent The corresponding abstract syntax tree is shown in the following
+figure. It directly gives the scattering functions (schedules) for all the
+statements of the program (just follow the paths).
+
+@image{images/tree,6cm}
+
+@tex
+$$
+\hbox{$ \cases{ \theta _{S1}(i,j)    &$=  (0,i,0,j,0)$\cr
+                \theta _{S2}(i)      &$=  (0,i,1)$\cr
+                \theta _{S3}(i,j,k)  &$=  (0,i,2,j,0,k,0)$\cr
+                \theta _{S4}(i,j)    &$=  (0,i,2,j,1)$}$}
+$$
+@end tex
+
+@ifnottex
+@example
+@group
+T_S1(i,j)   = (0,i,0,j,0)
+T_S2(i)     = (0,i,1)
+T_S3(i,j,k) = (0,i,2,j,0,k,0)
+T_S4(i,j)   = (0,i,2,j,1)
+@end group
+@end example
+@end ifnottex
+
+@noindent These schedules depend on the iterators and give for each instance
+of each statement a unique execution date. Using such scattering functions
+allows CLooG to re-generate the input code.
+
+@noindent To easily manipulate the scattering function of any
+statement @code{S}, we translate it to the matrix form:
+@tex
+@math{\theta_S}(@emph{iteration vector})
+@end tex
+@ifnottex
+T_S(@emph{iteration vector})
+@end ifnottex
+@code{ = }@strong{scattering matrix}@code{ * }@emph{iteration vector}.
+For instance let us consider again our previous example
+@tex
+$\theta_{S4}(i, j) = (j+2, 3*i+j).$
+@end tex
+@ifnottex
+T_S4(i,j) = (j+2,3*i+j).
+@end ifnottex
+We write it in the following way:
+@tex
+$$

+(the iteration vector is in general an implicit information).}
+
+
+@node Access Function
+@subsection Access Function
+
+Before applying any transformation, it is essential to deeply analyze both the
+original program and the transformation to ensure the transformation does not
+imply any modification of the original program semantics. In the polyhedral
+model, we are able to achieve
+an exact analysis when all the memory accesses are made through arrays
+(note that variables are a particular case of arrays since they are simply
+arrays with only one memory location) with affine subscripts that depend
+on outer loop counters and global parameters (note that @emph{subscripts}
+are sometimes called @emph{index} or @emph{accesses} in the literature).
+
+For instance let us consider the array access @code{A[2*i+j][j][i+N]}. It has
+three dimensions, each subscript dimension is an affine form of some outer loop
+iterarors (@code{i} and @code{j}) and global parameters (@code{N}) hence
+it corresponds to an acceptable array access to be analyzed in the
+polyhedral model.
+
+Each array access can target a different memory cell depending on the
+statement instance, i.e., depending on the iteration vector.
+Thus we use access functions (or subscript functions, or index functions, as you
+prefer to call it) depending on the iteration vector to describe an array
+access. In our example, the access function would be written
+@math{F_A(i, j) = (2*i+j, j, i+N)}.
+
+@noindent To easily manipulate the access function of any
+array @code{A}, we translate it to the matrix form:
+@math{F_A}(@emph{iteration vector})
+@code{ = }@strong{access matrix}@code{ * }@emph{iteration vector}.
+For instance let us consider again our previous example. We would
+write it in the following way:
+@tex
+$$
+F_A
+\left(
+\matrix{
+ i \cr
+ j \cr
+ N \cr

+OK, now you have an idea about how we do represent a program part in the

+representation to extract useful information about your
+code (data reuse, parallelism...) and to generate a scattering
+to benefit from the properties you analysed.

+It contains what is strictly necessary to build a
+complete source-to-source framework in the polyhedral model and to output a

+The second part of the format, the so-called @emph{extension part},
+contains extensions to provide additional informations to some tools.

+@section Preliminary Example
+OpenScop is a specification for representing static control program parts in
+the polyhedral model. Thus, we can translate some code parts to an equivalent
+OpenScop representation. As an example, let us consider the
+following matrix-multiply kernel:
+
+@example
+#pragma scop
+if (N > 0) @{
+  for (i = 0; i < N; i++) @{
+    for (j = 0; j < N; j++) @{
+      C[i][j] = 0.0;
+      for (k = 0; k < N; k++)
+        C[i][j] = C[i][j] + A[i][k] * B[k][j];
+    @}
+  @}
+@}
+@end example
+
+The Clan@footnote{@url{http://www.lri.fr/~bastoul/development/clan/}}
+tool may be used to translate this code part to an OpenScop
+representation automatically. The @code{#pragma scop} is used here for
+Clan, but some other tool may not need it. Here is the result of the
+translation to an OpenScop textual representation.

+
+The @samp{Context} and the @samp{Statements} parts compose the
+@emph{core part}, i.e., what is strictly necessary to build
+a complete source to source framework based on OpenSCop:
+@itemize @bullet
+@item  @samp{Context} represents the global information of the SCoP. It
+       consists on the target language, the global constraints on the
+       parameters and optionally the parameter information which may be necessary
+       for the code generation process. The constraints on the parameters
+       are represented as a relation (@pxref{Context Domain Relation}).
+       The parameter information is optional. It is preceded by a
+       boolean which precises whether it is provided or not.
+       It is a generic information (@pxref{Generics}), a @code{strings}
+       (@pxref{Strings Generic}) for instance.
+@item  @samp{Statements} represents the information about the statements.
+       @samp{Nb_statements} is the number of statements in the SCoP,
+       i.e. the number of @samp{Statement} items in the @samp{Statement_list}.
+       @samp{Statement} represents the information on a given statement.
+       To each statement is associated a list of relations and,
+       optionaly, a body. The list of relations may include
+       one iteration domain (@pxref{Iteration Domain Relation}),
+       one scattering relation (@pxref{Scattering Relation})
+       and several access relations (@pxref{Access Relation}).
+       There is no mandatory ordering, but for consistency reason it would
+       be much appreciated that iteration domain comes first (if present)
+       then scattering (if present), then accesses (if present).
+       The statement body is an optional information. It is preceded by a
+       boolean which precises whether it is provided or not. 
+       It is a generic information (@pxref{Generics}), a @code{body}
+       (@pxref{Body Generic}) for instance.

+
+The @samp{Extension_list} represents the @emph{extension part} and may contain
+an arbitrary number of generic informations (@pxref{Generics}).
+Few examples of possible extensions are presented in a further

+
+@emph{Relations} are the essence of the OpenScop format and contain the
+"polyhedral" information. They are used to describe either an iteration
+domain, or a context domain, or a scattering or a memory access.
+
+We use the relation term as a shortcut to denote a
+union of convex relations, each element of the union being described by a set of
+constraints in an extended PolyLib format (@pxref{Wil93}).
+The number of elements in the union is given by an integer on the first line,
+optionally followed by a comment starting with @samp{#}.
+This number of elements can be omitted when there is only one element.
+Each element in the union has the following syntax:
+
+@enumerate
+@item Some optional comment lines beginning with @samp{#}.
+@item A line with the type of the relation, possibly followed by comments.
+      The type can be one of the following:
+      @itemize @bullet
+      @item @code{UNDEFINED}: generic relation,
+      @item @code{CONTEXT}: for context information,
+      @item @code{DOMAIN}: for iteration domains,
+      @item @code{SCATTERING}: for scattering relation,
+      @item @code{READ}: for read accesses,
+      @item @code{WRITE}: for write accesses,
+      @item @code{MAY_WRITE}: for may-write accesses,
+      @end itemize
+@item A line with 6 numbers, possibly followed by comments:
+      @enumerate
+      @item the number of rows of the constraint matrix,
+      @item the number of columns of the constraint matrix,
+      @item the number of @emph{output dimensions},
+      @item the number of @emph{input dimension},
+      @item the number of @emph{local dimensions}
+            (existentially quantified dimensions),
+      @item the number of @emph{parameters}.
+      @end enumerate
+      The sum of the last four numbers should be equal to the number of columns
+      minus two. The remaining two columns are the equality/inequality
+      indicator and the constant term. The number of parameters should be the
+      same for all relations in the entire OpenScop file or data structure.
+@item The constraint rows. Each row corresponds to a constraint the
+      relation has to satisfy. Each row must be on a single line and is possibly
+      followed by comments. The constraint is an equality @math{p(x) = 0} if the
+      first element is 0, an inequality  @math{p(x) \geq 0} if the first element
+      is 1. The next elements are the coefficients of the output dimensions,
+      followed by coefficients of the input dimensions, the existentially
+      quantified dimensions and finally the parameters.
+      The last element is the constant term.
+@end enumerate
+
+This representation is the basis for several purposes. Examples for
+iteration domains (@pxref{Iteration Domain Relation}), context domains
+(@pxref{Context Domain Relation}), scattering
+relations (@pxref{Scattering Relation}) and
+access relations (@pxref{Access Relation}) are provided in further sections.

+@c %/**************************  ITERATION DOMAIN  ****************************
+@node Iteration Domain Relation
+@subsubsection Iteration Domain Relation
+
+Iteration domain represents the set of instances of the corresponding statement.
+OpenScop iteration domains are represented as relations with the following
+conventions:
+@itemize @bullet
+@item the type is @code{DOMAIN},
+@item there is 0 input dimension,
+@item loop iterators correspond to output dimensions.
+@end itemize
+
+@noindent For instance, assuming that @samp{i}, @samp{j} and @samp{k} are the loop
+iterators and @samp{M} and @samp{N} are the parameters, the domain defined by
+the following constraints :
+
+@tex
+$$
+\hbox{$ \cases{ -i     + M &$\geq 0$\cr
+                    -j + N &$\geq 0$\cr
+                 i + j - k &$\geq 0$}$}
+$$
+@end tex
+@ifnottex
+@example
+@group
+   -i + M >= 0
+   -j + N >= 0
+i + j - k >= 0
+@end group
+@end example
+@end ifnottex
+
+@noindent can be written in the input file as follows:
+
+@example
+@group
+# This is an iteration domain
+DOMAIN
+1 # Number of relations in the union
+3 7 3 0 0 2                  # 3 rows, 7 cols: 3 output dims and 2 params
+# e/i| i   j   k | M   N | 1
+   1  -1   0   0   1   0   0 #    -i + M >= 0
+   1   0  -1   0   0   1   0 #    -j + N >= 0
+   1   1   1  -1   0   0   0 # i + j - k >= 0
+@end group
+@end example
+
+@noindent Equivalently, it can be written in the following way as the number
+of relations in the union can be omitted if it is 1:
+
+@example
+@group
+# This is an iteration domain
+DOMAIN
+3 7 3 0 0 2                  # 3 rows, 7 cols: 3 output dims and 2 params
+# e/i| i   j   k | M   N | 1
+   1  -1   0   0   1   0   0 #    -i + M >= 0
+   1   0  -1   0   0   1   0 #    -j + N >= 0
+   1   1   1  -1   0   0   0 # i + j - k >= 0
+@end group
+@end example
+
+@noindent As an example for unions, let us consider the following pseudo-code:
+
+@example
+@group
+for (i = 1; i <= N; i++) @{
+  if ((i >= M) || (i <= 2*M))
+    S1(i);
+@}
+@end group
+@end example
+
+@noindent The iteration domain of @samp{S1} can be divided into two
+relations and written in the OpenScop file as follows:
+
+@example
+@group
+# This is an iteration domain
+DOMAIN
+2 # Number of relations in the union
+# Union part No.1
+3 5 1 0 0 2          # 3 rows, 5 cols: 1 output dim and 2 params
+# e/i| i | M   N | 1
+   1   1   0   0  -1 #  i >= 1
+   1  -1   0   1   0 #  i <= N
+   1   1  -1   0   0 #  i >= M
+# Union part No.2
+3 5 1 0 0 2          # 3 rows, 5 cols: 1 output dim and 2 params
+# e/i| i | M   N | 1
+   1   1   0   0  -1 #  i >= 1
+   1  -1   0   1   0 #  i <= N
+   1  -1   2   0   0 #  i <= 2*M
+@end group
+@end example
+
+@noindent As an example for local dimensions (existentially quantified
+dimensions), let us consider the following pseudo-code:
+
+@example
+@group
+for (i = 1; i <= N; i++) @{
+  if ((i % 2) == 0)
+    S1(i);
+@}
+@end group
+@end example
+
+@noindent The iteration domain of @samp{S1} is composed of all even
+integer values between 1 and N. The "divisible by two" constraint can
+be expressed as follows: there exists an integer @samp{ld} such that
+@samp{i = 2*ld}. We encode this thanks to a new local dimension:
+
+@example
+@group
+# This is an iteration domain
+DOMAIN
+3 5 1 0 1 1          # 3 rows, 5 cols: 1 output dim, 1 local dim, 1 param
+# e/i| i |ld | N | 1
+   0   1  -2   0   0 #  i = 2*ld
+   1   1   0   0   1 #  i >= 1
+   1  -1   0   1   0 #  i <= N
+@end group
+@end example
+
+
+@c %/**************************  CONTEXT DOMAIN  ******************************
+@node Context Domain Relation
+@subsubsection Context Domain Relation
+
+The context domain is a particular case of iteration domain
+(@pxref{Iteration Domain Relation}) where there are only
+constraints about parameters (no loop iterators). Hence it is the same
+as an iteration domain, with the following conventions:
+@itemize @bullet
+@item the type is @code{CONTEXT},
+@item there is 0 input dimension,
+@item there is 0 output dimension.
+@end itemize
+
+
+@c %/*************************  SCATTERING RELATION  **************************
+@node Scattering Relation
+@subsubsection Scattering Relation
+
+Scattering relation maps an iteration domain to a logical time and/or
+space (and/or) anything.
+OpenScop scattering information is represented as relations
+(@pxref{Relations}) with the following conventions:
+
+@itemize @bullet
+@item the type is @code{SCATTERING},
+@item output dimensions correspond to scattering dimensions,
+@item loop iterators correspond to input dimensions.
+@end itemize
+
+As an example of a scattering relation and
+assuming that @samp{i}, @samp{j} and @samp{k} are the loop
+iterators and @samp{M} and @samp{N} are the parameters, take for instance:
+@tex
+$\theta_{S}(i,j,k) = (j+2,3*i+j,k+N+1).$
+@end tex
+@ifnottex
+@example
+T_@{S@}(i,j,k) = (j+2,3*i+j,k+N+1).
+@end example
+@end ifnottex
+We can represent it in the following way:
+
+@example
+@group
+# A scattering relation
+SCATTERING
+# 3 rows, 10 columns: 3 scattering dimensions, 3 iterators, 2 parameters
+3 10 3 3 0 2
+# e/i|s1  s2  s3 | i   j   k | M   N | 1
+   0  -1   0   0   0   1   0   0   0   2 # s1 = j+2
+   0   0  -1   0   3   1   0   0   0   0 # s2 = 3*i+j
+   0   0   0  -1   0   0   1   0   1   1 # s3 = k+N+1
+@end group
+@end example
+
+@c %/**************************  ACCESS RELATION  *****************************
+@node Access Relation
+@subsubsection Access Relation
+
+Access relation maps an iteration domain to an array space.
+Each array accessed in the SCoP has a unique identification number.
+OpenScop relation information is represented as relations
+(@pxref{Relations}) with the following conventions:
+
+@itemize @bullet
+@item the type is one of the following:
+      @itemize @bullet
+      @item @code{READ}, for read accesses,
+      @item @code{WRITE}, for write accesses,
+      @item @code{MAY_WRITE}, for may write accesses,
+      @end itemize
+@item output dimensions correspond to the array identifier and dimensions,
+@item the first output dimension corresponds to the array identifier,
+@item the (i+1)th output dimension corresponds to the ith array dimension (i>1),
+@item loop iterators correspond to input dimensions.
+@end itemize
+
+As an example of a scattering relation and
+assuming that @samp{i}, @samp{j} and @samp{k} are the loop
+iterators and @samp{M} and @samp{N} are the parameters, let us consider
+the array access @code{A[2*i+j][j][i+N]} (the identifier of @code{A} is 42),
+and let us suppose this is a read access. Its representation would be the
+following:
+
+@example
+@group
+# A read access relation
+READ
+# 4 rows, 11 columns: 4 array dimensions, 3 iterators, 2 parameters
+4 11 4 3 0 2
+# e/i|Arr [1] [2] [3]| i   j   k | M   N | 1

+
+To understand this representation, consider that OpenScop accesses
+are general memory accesses and not array accesses. The memory is
+seen as a big array @code{Mem} while usual array names correspond to
+the first dimension. Hence our example translates to @code{Mem[42][2*i+j][j][i+N]}.
+
+Unions of access relations are allowed. In this case, each union part must
+refer at the same array identifier, and the number of dimensions must be
+consistent.

+
+@emph{Generics} represent any elaborated non-polyhedral information in the
+OpenScop format. They are used to represent the parameter information, the
+statement body information as well as the extensions. Each generic information
+is delimited using XML-like tags corresponding to its URI (Unique Resource
+Identifier), For instance, if the generic has the URI @code{foo}, the begin
+tag is @code{<foo>} and the end tag is @code{</foo>}).
+
+Two generics, namely @code{strings} (@pxref{Strings Generic}) and
+@code{body} (@pxref{Body Generic}) are part of the OpenScop
+specification to provide the minimum, stricly necessary information to
+build a complete source-to-source polyhedral framework based on OpenScop.
+However, generics can be basically @emph{anything} as long as they are
+properly delimited. OpenScop implementations will simply ignore
+non-supported generics and warn the user with the mention of the
+non-supported URIs. Support of new generics will be added throught the
+extension mechanism.
+
+@c ---------------------------------------------------------------------------
+
+@node Strings Generic
+@subsubsection Strings Generic
+
+The purpose of the @code{strings} generic is to represent a list of
+textual strings on one line (which may be used, e.g., to represent the list of
+parameter names in the order used in the relation). Its URI is @code{strings}
+and its file format respects the following grammar:
+@example
+Strings_generic     ::= "<strings>" Strings "</strings>"
+Strings             ::= _String String_list  | (void)
+@end example
+
+@noindent A possible example of textual @code{strings} is the following:
+@example
+@group
+<strings>
+Not one sentence but 6 strings!
+</strings>
+@end group
+@end example
+
+@c ---------------------------------------------------------------------------
+
+@node Body Generic
+@subsubsection Body Generic
+
+The purpose of the @code{body} generic is to represent the textual
+information about a statement. It contains the number of original iterators on
+the first line, the list of original iterators on the second
+line (the loop counters of the statement surrounding loops in the original
+program) and the original textual body expression on the third line.
+Its URI is @code{body} and its file format respects the following grammar
+(the @code{String} rule is reused, @pxref{Strings Generic}):
+@example
+Body_generic        ::= "<body>" Body "</body>"
+Body                ::= Nb_iterators Iterator_list Expression
+Nb_iterators        ::= _Integer
+Iterator_list       ::= Strings
+Expression          ::= Strings
+@end example
+
+@noindent A possible example of textual @code{body} is the following:
+@example
+@group
+<body>
+# Number of original iterators
+2
+# Original iterators
+i j
+# Original statement expression
+A[i+j] += B[i] * C[j];

+
+The OpenScop specification offers a small set of C data structures devoted to
+represent a SCoP in memory in a convenient way. Using them in some tool or
+library may greatly facilitate its interaction with other tools or libraries
+which rely on this representation as well. Every field may not be useful for
+a given tool or library. A general rule for all the data structure is
+that a @code{NULL} pointer or a -1 integer value means the information is
+not present. Contrary to engineering time, memory is cheap today, so it's much
+probably not a big deal that some fields are left empty. Every field may not
+be enough for a given tool or library. In this case it is much recommended
+to provide a new extension which may be reused by other users
+(@pxref{Extensions}).
+
+Each tool or library may have its own implementation of the OpenScop
+data structures. The type names should not be the same as those provided
+as an example here (they correspond to the OpenScop Library implementation).
+The names of the fields, and their ordering, should however be the same. In this
+way, the interaction between tools and libraries should be as simple as a cast.
+
+Before reading at the OpenScop data structures, it is much recommended to
+read at the OpenScop file format description, as it is quite close to this
+representation (@pxref{OpenScop File Format Specification}).

+First, it contains the informations about the context. The target language
+in expressed in the @code{language} field. The constraints on the

+@section Extensions
+
+The core part of the OpenScop representation embeds what is strictly
+necessary to build a complete source-to-source polyhedral framework.
+However it may not be enough. Hence, OpenScop offers a very flexible
+extension part. Actually, the only constraint to build an extension is
+to request the OpenScop maintainer for a unique extension name: its URI
+(ask the maintainer through the OpenScop mailing list
+@email{openscop-development@@googlegroups.com}).
+
+The policy to support extensions is the following and is pretty simple: an
+OpenScop implementation is not required to support any extension. If it
+is processing an OpenScop file or data structure which contains an
+extension which is not supported, it must (1) warn the user with the 
+mention of the URI of the non-supported extension
+and (2) ignore this extension.
+
+Extensions in an OpenScop file are provided after the core part, without
+any specific order. Each extension is delimited using
+XML-like tags corresponding to its URI (e.g., if the extension has the URI
+@code{foo}, the begin tag is @code{<foo>} and the end tag is @code{</foo>}).
+There is no specification or preferred way to write the extension body.
+Extensions in an OpenScop data structure must be accessible through one
+pointer. This pointer will be stored in the @code{data} field of an
+@code{osl_generic_t} container (@pxref{osl_generic_t}). There must be only
+one extension with the same URI in an OpenScop file or data structure.
+
+Extension writers may write a short documentation about their extension to
+be added to this document. For consistency reason, this
+documentation should comply to the documentation of the
+@code{comment} option (@pxref{Comment Extension}). To describe the
+file format, it is allowed to reuse the existing rules and terminals
+present in the OpenScop file format description without defining them
+(@pxref{OpenScop File Format Specification}). By sending a
+documentation, you accept it to be added to this document. In
+particular, the sender fully accepts the license and copyright notice.

+@chapter OpenScop Library
+
+The OpenScop Library, or OSL for short, is an example implementation of the
+OpenScop specification. Its API is not part of the OpenScop specification. 
+It offers basic functionalities to manipulate the OpenScop data structures
+(allocate, free, copy, dump, etc.) and file format (read, print, etc.).
+The OpenScop Library is @emph{not} a polyhedral library. OpenScop is an
+exchange format, and the OpenScop Library reflects this. 
+
+It is a Free Software using the 3-clause BSD License.
+Programmers should feel free to use
+it or copy/paste its code in any project, Open Source or not@footnote{Closed
+source projects should consider to provide some OpenScop file input
+and output, so they can be incorporated to any OpenScop-based tool chain.}.

+@section Precision
+
+The OpenScop specification does not impose a specific type for the
+constraint matrix elements. For a maximum flexibility, the OpenScop Library
+offers an hybrid precision implementation. It supports 32 bits, 64 bits and
+multiple precision (relying on GNU GMP) relations transparently. At relation
+allocation time, users have two ways to set the precision. The first way is
+to call an allocation function with a precision parameter. The second way is
+to rely on the environment variable @code{OSL_PRECISION}.
+The accepted values for this variable are @code{32} for 32 bits precision,
+@code{64} for 64 bits precision and @code{0} for multiple precision. When this
+variable is set, its value becomes the default precision for relation elements.
+For instance, to ensure the OpenScop Library will use 64 bits precision
+by default, the user may set: 
+@example
+export OSL_PRECISION=64
+@end example
+@noindent if his shell is, e.g., bash or
+@example
+setenv OSL_PRECISION 64
+@end example
+@noindent if his shell is, e.g., tcsh. The user should ad this line to
+his .bashrc or .tcshrc (or whatever convenient file) to make this
+setting permanent. 
+
+@node Base Functions
+@section Base Functions
+
+The OpenScop Library provides, for each OpenScop data structure,
+a set of functions devoted to basic manipulation, conversion
+from file format to data structures and from data structures to
+file format. The naming convention is consistent for all data
+structures. Hence, the function prototypes differ only with the
+name of the data structure. In the following, we will use the
+generic term of @emph{structure} to refer at any OpenScop
+data structure. For instance the
+@code{osl_}@emph{structure}@code{_malloc()} function is a
+generic name can be instantiated to
+@code{osl_relation_malloc()} or
+@code{osl_statement_malloc()} etc.
+
+We present in this documentation only
+the main functions. Many other utility functions are provided
+to ease OpenScop format manipulation. The reader is invited to
+refer at the technical documentation to learn everything about the
+OpenScop Library.

+@node Dumping
+@subsection Dumping: osl_@emph{structure}_dump and idump 
+
+@example
+@group
+void osl_@emph{structure}_dump(FILE * output, osl_@emph{structure}_p s);
+void osl_@emph{structure}_idump(FILE * output, osl_@emph{structure}_p s, int i);
+@end group
+@end example
+
+@noindent Each OpenScop data structure has a dumping functions
+as shown above. Dumping means writing down the content of the data
+structure pointed by @code{s} (and its fields recursively)
+in a textual form to the
+@code{output} file (the file, possibly @code{stdout}, has to be open
+for writing). The textual form is not the OpenScop file format but
+another representation closer to the internal representation in
+memory and mainly intended for debugging purpose. The @code{idump}
+function has an additional integer parameter which corresponds to
+an indentation level.
+
+@node Printing
+@subsection Printing: osl_@emph{structure}_print
+
+@example
+@group
+void osl_@emph{structure}_print(FILE * output, osl_@emph{structure}_p s);
+@end group
+@end example
+
+@noindent Each OpenScop data structure has a pretty printing function
+as shown above. It prints the content of the data
+structure pointed by @code{s} (and its fields recursively)
+according to the OpenScop file format
+(@pxref{OpenScop File Format Specification}) to the
+@code{output} file (the file, possibly @code{stdout}, has to be open
+for writing).
+
+@node Reading
+@subsection Reading: osl_@emph{structure}_read
+
+@example
+@group
+osl_@emph{structure}_p osl_@emph{structure}_read(FILE * input);
+@end group
+@end example
+
+@noindent Each OpenScop data structure has a reading function
+as shown above. It reads the content of an OpenScop
+data structure written according to the OpenScop file format 
+(@pxref{OpenScop File Format Specification}) from 
+the @code{input} file (the file, possibly @code{stdin}, has to be open
+for reading). It returns a pointer to a freshly allocated 
+@code{osl_@emph{structure}_t} structure containing the
+information.
+
+@node Allocating
+@subsection Allocating: osl_@emph{structure}_malloc
+
+@example
+@group
+osl_@emph{structure}_p osl_@emph{structure}_malloc();
+@end group
+@end example
+
+@noindent Each OpenScop data structure has a memory allocation function
+as shown above (except one see below). It allocates the memory to store
+the corresponding data structure, it initializes the pointer fields to
+@code{NULL} and the integer fields to @code{OSL_UNDEFINED}
+(@code{-1}) and it returns a pointer to the allocated space.
+
+An exception to this base description is the
+@code{osl_relation_malloc()} function which requires two
+parameters: the number of rows and columns of the constraint
+matrix (@pxref{Relations}):
+
+@example
+@group
+osl_relation_p osl_relation_malloc(int nb_rows, int nb_columns);
+@end group
+@end example
+
+@noindent The precision of the relation elements will depend on the
+@code{OSL_PRECISION} environment variable (@pxref{Precision}) if it is set,
+or the maximum available precision if it is not set. Another allocation
+function is provided to explicitly set a given precision:
+
+@example
+@group
+osl_relation_p osl_relation_pmalloc(int precision,
+                                    int nb_rows, int nb_columns);
+@end group
+@end example
+
+@noindent The @code{precision} field may take the following values:
+@itemize @bullet
+@item @code{OSL_PRECISION_SP} for 32 bits precision,
+@item @code{OSL_PRECISION_DP} for 64 bits precision,
+@item @code{OSL_PRECISION_MP} for multiple precision,
+@end itemize
+
+@node Deallocating
+@subsection Deallocating: osl_@emph{structure}_free
+
+@example
+@group
+void osl_@emph{structure}_free(osl_@emph{structure}_p s);
+@end group
+@end example
+
+@noindent Each OpenScop data structure has a memory deallocation function
+as shown above. It recursively frees the memory allocated for the
+structure pointed by @code{s}, i.e., internal structures are also freed.
+
+@node Cloning
+@subsection Cloning: osl_@emph{structure}_clone
+
+@example
+@group
+osl_@emph{structure}_p osl_@emph{structure}_clone(osl_@emph{structure}_p s);
+@end group
+@end example
+
+@noindent Each OpenScop data structure has a clone function
+as shown above. It recursively copies the content of the
+structure pointed by @code{s}, i.e., internal structures are also copied.
+It returns a pointer to the clone of the structure pointed by @code{s}.
+
+@node Testing
+@subsection Testing: osl_@emph{structure}_equal
+
+@example
+@group
+int osl_@emph{structure}_equal(osl_@emph{structure}_p s1, osl_@emph{structure}_p s2);
+@end group
+@end example
+
+@noindent Each OpenScop data structure has a testing function
+as shown above. It checks whether two pointers are referring to equivalent
+structures (either by pointing to the same structure or to different
+structures which contain the same information). It returns 1 if the
+pointed structures are equivalent, 0 otherwise. This test is
+@emph{content-based} and is intended for debugging purpose. It is not
+(and will never be) able to state, e.g., that two relations with
+different constraint matrices are actually representing the same relation.
+
+
+@node Example of OpenScop Library Utilization
+@section Example of OpenScop Library Utilization
+Here is a basic example showing how it is possible to use the
+OpenScop Library, assuming that a standard installation has been done.
+The following C program reads an OpenScop file from the standard
+input and dumps the content of the data structures to the standard output.
+
+@example
+/* example.c */
+# include <stdio.h>
+# include <osl/osl.h>
+
+int main() @{
+  osl_scop_p scop;
+
+  // Read the OpenScop file.
+  scop = osl_scop_read(stdin);
+
+  // Dump the content of the scop data structure.
+  osl_scop_dump(stdout, scop);
+
+  // Save the planet.
+  osl_scop_free(scop);
+
+  return 0;
+@}
+@end example
+
+@noindent The compilation command could be:
+@example
+gcc example.c -losl -o example
+@end example
+@noindent A calling command with the input file test.scop could be:
+@example
+more test.scop | ./example
+@end example

+@node Requirements
+@subsection Requirements
+
+The OpenScop Library is a stand-alone library. For a basic use,
+it does not need any additional tool or library. Anyway, to be able to
+work in conjunction with other tools that manipulate multiple precision
+numbers, the GNU GMP library can be used as an option.
+
+@menu
+* GMP Library::
+@end menu
+
+
+@node GMP Library
+@subsubsection GMP Library (optional)
+
+To be able to deal with insanely large coefficient, the user will need to
+install the GNU Multiple Precision Library (GMP for short) version 4.2.2
+or above@footnote{@code{http://www.swox.com/gmp}}.
+The user can compile it by typing the following commands on the GMP root
+directory:
+
+@itemize @bullet
+@item @code{./configure}
+@item @code{make}
+@item And as root: @code{make install}
+@end itemize
+
+The GMP default installation is @code{/usr/local}. This directory may
+not be inside the user's library path. To fix the problem, the user should set
+@example
+export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
+@end example
+@noindent if your shell is, e.g., bash or
+@example
+setenv LD_LIBRARY_PATH $LD_LIBRARY_PATH:/usr/local/lib
+@end example
+@noindent if your shell is, e.g., tcsh. Add the line to your .bashrc or .tcshrc (or
+whatever convenient file) to make this change permanent. Another solution
+is to ask GMP to install in the standard path by using the prefix
+option of the configure script:
+@samp{./configure --prefix=/usr}.
+
+The OpenScop Library has to be built using the GMP library by specifying
+the convenient configure script options to buid the GMP version
+(@pxref{Optional Features}).
+
+
+@node Installation Instructions
+@subsection Installation Instructions
+
+Once downloaded and unpacked
+(e.g. using the @samp{tar -zxvf openscop-@value{LIB_VERSION}.tar.gz} command),
+you can compile the OpenScop Library by typing the following commands
+on the OpenScop Library's root directory:
+
+@itemize @bullet
+@item @code{./autogen.sh}
+@item @code{./configure}
+@item @code{make}
+@item And as root: @code{make install}
+@end itemize
+
+The program binaries and object files can be removed from the
+source code directory by typing @code{make clean}. To also remove the
+files that the @code{configure} script created (so you can compile the
+package for a different kind of computer) type @code{make distclean}.
+
+@node Optional Features
+@subsection Optional Features
+The @code{configure} shell script attempts to guess correct values for
+various system-dependent variables and user options used during compilation.
+It uses those values to create the @code{Makefile}. Various user options
+are provided by the OpenScop Library's configure script. They are summarized in the
+following list and may be printed by typing @code{./configure --help} in the
+OpenScop Library top-level directory.
+
+@itemize @bullet
+@item By default, the installation directory is @code{/usr/local}:
+@code{make install} will install the package's files in
+@code{/usr/local/bin}, @code{/usr/local/lib} and @code{/usr/local/include}.
+The user can specify an installation prefix other than @code{/usr/local} by
+giving @code{configure} the option @code{--prefix=PATH}.
+
+@item By default, The OpenScop Library supports 32 bits, 64 bits and GMP if
+it is installed in the standard locations. Using the @code{--with-gmp} option
+of @code{configure} the user can specify that no GMP (@code{--with-gmp=no}),
+a previously installed (@code{--with-gmp=system}, the default) GMP or a
+build GMP (@code{--with-gmp=build}) GMP should be used.
+In case of an installed GMP, the installation location can be specified
+using the @code{--with-isl-prefix=PATH} and if different, the installation
+of the library can be specified using the
+@code{--with-isl-exec-prefix=PATH} options of @code{configure}.
+In the case of a build GMP, the user can also specify the build location
+using @code{--with-isl-builddir=PATH}.
+@end itemize
+
+@node Uninstallation
+@subsection Uninstallation
+The user can easily remove the OpenScop Library from his system
+by typing (as root if necessary) from the OpenScop Library top-level
+directory
+@code{make uninstall}.
+
+@c %  **************************** DOCUMENTATION ******************************
+@node Documentation
+@section Documentation
+The OpenScop Library distribution provides several sources of documentation.
+First, the source code itself is as documented as much as possible.
+The code comments use the Doxygen technical documentation system.
+The user may install
+Doxygen@footnote{@code{http://www.stack.nl/~dimitri/doxygen}} to automatically
+generate a technical documentation by typing @code{make doc} or
+@code{doxygen ./autoconf/Doxyfile} at the OpenScop Library
+top-level directory after running the configure script
+(@pxref{Installation Instructions}). Doxygen will generate
+documentation sources (in HTML, LaTeX and man) in the @code{doc/source}
+directory of the OpenScop Library distribution.
+
+The Texinfo source of the present document is also provided in the @code{doc}
+directory. The user can build it in either PDF format
+(by typing @code{texi2pdf openscop.texi}) or HTML format
+(by typing @code{makeinfo --html openscop.texi}, using @code{--no-split}
+option to generate a single HTML file) or info format
+(by typing @code{makeinfo openscop.texi}).

+
+@node Copyright Issue 
+@subsection Copyright Issue
+
+The OpenScop Library is an Open Source project and you should feel free to
+contribute by adding functionalities (in particular extensions), correcting
+bugs or improving documentation. However, for painful administrative reasons,
+the copyright of the core part (everything except extensions) should not be
+impacted by your work. Hence, if you are doing a significant contribution to
+the main part, the OpenScop Library maintainer may ask you for an agreement
+about this copyright. If you plan to do such a significant contribution, it
+may be wise to discuss this issue with the maintainer first. Extensions
+may include developer's own copyright.
+
+@node Repository 
+@subsection Repository
+
+The main repository of the OpenScop Library is
+@url{http://repo.or.cz/w/openscop.git}. Developers may ask the OpenScop Library
+maintainer to open them a write access to this repository. Only the maintainer
+should ever change the @code{master} branch. Developers should work on their
+own branches. To avoid any problem developers should use the @emph{fork}
+functionality of the repository.
+
+@node Coding Style 
+@subsection Coding Style  
+
+The OpenScop Library is written in C using an object oriented style. Each
+important data structure (e.g., @code{struct foo}) has its own header file
+(@code{include/osl/foo.h}) where lies the definition of
+the data structure, the two typedefs for the data structure (one for the
+structure, @code{osl_foo_t}, and one for a pointer
+to the structure, @code{osl_foo_p}), the prototypes of the various
+functions related to this data structure, all named using the
+prefix "@code{osl_foo_}". The source code of the functions is provided in a
+separated C file (@code{source/foo.c}).
+  
+Utility functions independent from the main data structures may be placed in
+separate source files (e.g., definition in @code{include/osl/util.h}
+and code in @code{source/util.c}). Tool-wide preprocessor directives are
+placed in @code{include/osl/macros.h}, macros are prefixed with
+"@code{OSL_}".
+
+The core code itself has to be written according to the Google C++ Coding Style:
+@url{http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml} (for
+what can apply to C), plus the naming conventions discussed above with
+highest priority. The extension parts must only respect the naming convention,
+but a consistent coding style is much appreciated.
+
+@node Extension Development
+@subsection Extension Development
+
+It's fairly easy to integrate a new extension to OpenScop and the OpenScop
+Library. Developing a new extension is very much like adding a new "object":
+it requires writing a data structure for the extension data and the 7 base
+functions to manage this extension. Here is how developers should proceed
+to add an extension called @code{foo} (beware that the naming convention is
+strict):
+
+@enumerate
+@item Send the name @code{foo} to the maintainer to ensure it is unique and
+      hence can be used as an URI. The name (one single
+      word, or words separated with underscores "_") should be
+      suggested by the extension developers to the OpenScop development
+      mailing list @email{openscop-development@@googlegroups.com}). It
+      should not correspond to an existing structure name
+      (see @code{include/osl/osl.h} for the list). The
+      maintainer will update @code{include/osl/osl.h} in the development
+      version accordingly.
+@item Look at the @code{comment} extension. The @code{comment} extension
+      (@pxref{Comment Extension}) has been written to be used as a basic
+      example for extension developers. Having a look at
+      @code{include/osl/extensions/comment.h} and
+      @code{source/extensions/comment.c} will be a great help to do it right.
+@item Create the extension data structure: it is necessary that the
+      extension data can be accessible through only one pointer.
+@item Code the 7 base functions for the extension. Any extension must provide
+      this set of functions (naming convention apply only if the
+      extension is planed to be integrated to the OpenScop Library
+      default extensions):
+      @itemize @bullet
+      @item @code{osl_foo_idump} (@pxref{Dumping}) 
+      @item @code{osl_foo_sprint} has the following prototype:
+@example
+@group
+char * osl_@emph{structure}_sprint(osl_@emph{structure}_p s);
+@end group
+@end example
+           It corresponds to the pretty printing functions of the core
+           data structures (@pxref{Printing}) with the
+           difference that the OpenScop textual representation is written
+           to a string (returned by the function) instead of a file.
+      @item @code{osl_foo_sread} has the following prototype:
+@example
+@group
+osl_@emph{structure}_p osl_@emph{structure}_sread(char ** string);
+@end group
+@end example
+           It corresponds to the reading functions of the core
+           data structures (@pxref{Reading}) with the
+           difference that the OpenScop textual representation is read
+           from a string (provided as a parameter) instead of a file.
+           The address of the string to read is passed as a parameter and
+           is updated to point immediately after what has been actually read.
+      @item @code{osl_foo_malloc} (@pxref{Allocating}) 
+      @item @code{osl_foo_free} (@pxref{Deallocating}) 
+      @item @code{osl_foo_clone} (@pxref{Cloning}) 
+      @item @code{osl_foo_equal} (@pxref{Testing}) 
+      @end itemize
+@item Code the other functions you need!
+@end enumerate
+
+Now let us consider two scenarios.
+
+First scenario, the extension is external and is
+not planned to be integrated to the OpenScop Library. In this case you are
+all set. Simply generate an @code{osl_interface_t} for your
+extension and have a look at the function
+@code{osl_scop_register_extension()} which is devoted to register
+a new extension interface to an existing @code{osl_scop_t}.
+
+Second scenario, the extension will integrate the set of default
+OpenScop Library extensions (the best solution to share it to other
+potential users). In this case, a few additional
+things have to be done:
+@enumerate
+@item Create the extension header
+      @code{include/osl/extensions/foo.h} to store the extension
+      structure and function prototypes and the
+      extension source file @code{source/extensions/foo.c} for the code
+      of the functions.
+@item Add the documentation for the extension to the texinfo source of
+      this document (in @code{doc/openscop.texi}), following the example
+      of the @code{comment} documentation (@pxref{Comment Extension}).
+@item Integrate the extension by adding the @code{extensions/foo.c} entry
+      to the @code{libosl_la_SOURCES} in the @code{source/Makefile.am}
+      file, the @code{osl/foo.h} entry to the
+      @code{nobase_pkginclude_HEADERS} and add the corresponding
+      @code{#include <osl/extensions/foo.h>} in the
+      @code{include/scop.h.in} file.
+@item Add the new extension in the
+      @code{osl_interface_get_default_registry()} function.
+@item You are done! Prepare a single commit or patch corresponding to the
+      integration of the new extension and ask the maintainer to merge it
+      to the master branch.

+/**
+ * The osl_relation_t structure stores a union of relations. It is a
+ * NULL-terminated linked list of relations. Each relation is described
+ * using a matrix where each row represents a linear constraint. The entries
+ * of each row are organised in the following order:
+ * - An equality/inequality tag: 0 means the row corresponds to an
+ *   equality constraint == 0, 1 means it is an inequality >= 0.
+ * - The coefficients of the output dimensions.
+ * - The coefficients of the input dimensions (0 for a set).
+ * - The coefficients of the local (existentially quantified) dimensions.
+ * - The coefficients of the parameters.
+ * - The coefficient of the constant.
+ * Thus we have the following invariant: nb_columns =
+ * 1 + nb_output_dims + nb_input_dims + dims + nb_parameters + 1.
+ * Moreover we use the following conventions:
+ * - Sets (e.g., iteration domains) are the images of relations with a
+ *   zero-dimensional domain, hence the number of input dimensions is 0.
+ * - The first output dimension of any access relations corresponds to
+ *   the name of the array.
+ * The type field may provide some semantics about the relation, it may be:
+ * - Undefined : OSL_UNDEFINED,
+ * - An iteration domain : OSL_TYPE_DOMAIN,
+ * - A scattering relation : OSL_TYPE_SCATTERING,
+ * - An access relation : OSL_TYPE_ACCESS.

+#
+# SYNOPSIS
+#
+#   AX_CC_MAXOPT
+#
+# DESCRIPTION
+#
+#   Try to turn on "good" C optimization flags for various compilers and
+#   architectures, for some definition of "good". (In our case, good for
+#   FFTW and hopefully for other scientific codes. Modify as needed.)
+#
+#   The user can override the flags by setting the CFLAGS environment
+#   variable. The user can also specify --enable-portable-binary in order to
+#   disable any optimization flags that might result in a binary that only
+#   runs on the host architecture.
+#
+#   Note also that the flags assume that ANSI C aliasing rules are followed
+#   by the code (e.g. for gcc's -fstrict-aliasing), and that floating-point
+#   computations can be re-ordered as needed.
+#
+#   Requires macros: AX_CHECK_COMPILER_FLAGS, AX_COMPILER_VENDOR,
+#   AX_GCC_ARCHFLAG, AX_GCC_X86_CPUID.

+#
+#   AX_CFLAGS_WARN_ALL [(shellvar [,default, [A/NA]])]
+#
+# DESCRIPTION
+#
+#   Try to find a compiler option that enables most reasonable warnings.
+#
+#   For the GNU CC compiler it will be -Wall (and -ansi -pedantic) The
+#   result is added to the shellvar being CFLAGS by default.
+#
+#   Currently this macro knows about GCC, Solaris C compiler, Digital Unix C
+#   compiler, C for AIX Compiler, HP-UX C compiler, IRIX C compiler, NEC
+#   SX-5 (Super-UX 10) C compiler, and Cray J90 (Unicos 10.0.0.8) C
+#   compiler.
+#
+#    - $1 shell-variable-to-add-to : CFLAGS
+#    - $2 add-value-if-not-found : nothing
+#    - $3 action-if-found : add value to shellvariable
+#    - $4 action-if-not-found : nothing

+# SYNOPSIS
+#
+#   AX_GCC_ARCHFLAG([PORTABLE?], [ACTION-SUCCESS], [ACTION-FAILURE])
+#
+# DESCRIPTION
+#
+#   This macro tries to guess the "native" arch corresponding to the target
+#   architecture for use with gcc's -march=arch or -mtune=arch flags. If
+#   found, the cache variable $ax_cv_gcc_archflag is set to this flag and
+#   ACTION-SUCCESS is executed; otherwise $ax_cv_gcc_archflag is is set to
+#   "unknown" and ACTION-FAILURE is executed. The default ACTION-SUCCESS is
+#   to add $ax_cv_gcc_archflag to the end of $CFLAGS.
+#
+#   PORTABLE? should be either [yes] (default) or [no]. In the former case,
+#   the flag is set to -mtune (or equivalent) so that the architecture is
+#   only used for tuning, but the instruction set used is still portable. In
+#   the latter case, the flag is set to -march (or equivalent) so that
+#   architecture-specific instructions are enabled.
+#
+#   The user can specify --with-gcc-arch=<arch> in order to override the
+#   macro's choice of architecture, or --without-gcc-arch to disable this.
+#
+#   When cross-compiling, or if $CC is not gcc, then ACTION-FAILURE is
+#   called unless the user specified --with-gcc-arch manually.
+#
+#   Requires macros: AX_CHECK_COMPILER_FLAGS, AX_GCC_X86_CPUID
+#
+#   (The main emphasis here is on recent CPUs, on the principle that doing
+#   high-performance computing on old hardware is uncommon.)

+# SYNOPSIS
+#
+#   AX_GCC_X86_CPUID(OP)
+#
+# DESCRIPTION
+#
+#   On Pentium and later x86 processors, with gcc or a compiler that has a
+#   compatible syntax for inline assembly instructions, run a small program
+#   that executes the cpuid instruction with input OP. This can be used to
+#   detect the CPU type.
+#
+#   On output, the values of the eax, ebx, ecx, and edx registers are stored
+#   as hexadecimal strings as "eax:ebx:ecx:edx" in the cache variable
+#   ax_cv_gcc_x86_cpuid_OP.
+#
+#   If the cpuid instruction fails (because you are running a
+#   cross-compiler, or because you are not using gcc, or because you are on
+#   a processor that doesn't have this instruction), ax_cv_gcc_x86_cpuid_OP
+#   is set to the string "unknown".
+#
+#   This macro mainly exists to be used in AX_GCC_ARCHFLAG.

+ * 1. The guard of the loop, i.e. each constraint in the domain that does not
+ *    depend on the iterator (when the entry in the column 'level' is 0).
+ * 2. The iteration domain of the iterator, given by the constraints in the
+ *    domain depending on the iterator, i.e.:
+ *    * an equality if the iterator has only one value (possibly preceded by
+ *      a guard verifying if this value is integral), *OR*
+ *    * a loop from the minimum possible value of the iterator to the maximum
+ *      possible value.
+ * 3. The included statement block.
+ * 4. The inner loops (recursive call).
+ * 5. The following loops (recursive call).
+ * - level is the recursion level or the iteration level that we are printing,
+ * - the infos structure gives the user some options about code printing,
+ *   the number of parameters in domain (nb_par), and the arrays of iterator
+ *   names and parameters (iters and params).

+ * - June      29th 2003: non-unit strides support.
+ * - April     28th 2005: (debug) level is level+equality when print statement!
+ * - June      16th 2005: (debug) the N. Vasilache normalization step has been
+ *                        added to avoid iteration duplication (see DaeGon Kim

  * This function reads names data from a file (file, possibly stdin). It first
- * reads the naming option to know if whether has to automatically generate the
- * names, or to read them. Names are stored into an array of strings, and a
- * pointer to this array is returned.
+ * reads the naming option to know if whether it can read the names from the
+ * file.  If not, NULL is returned.  Otherwise, the names are stored
+ * into an array of strings, and a pointer to this array is returned.
  * - nb_items is the number of names the function will have to read if the
  *   naming option is set to read.
- * - prefix is the prefix to give to each name in case of automatic generation.
- * - first item is the name of the first suffix in case of automatic generation.

-/**
- * cloog_domain_lazy_block function:
- * This function returns 1 if the two domains d1 and d2 given as input are the
- * same (possibly except for a dimension equal to a constant where we accept
- * a difference of 1) AND if we are sure that there are no other domain in
- * the code generation problem that may put integral points between those of
- * d1 and d2 (0 otherwise). In fact this function answers the question "can I
- * safely consider the two domains as only one with two statements (a block) ?".
- * This function is lazy: it asks for very standard scattering representation
- * (only one constraint per dimension which is an equality, and the constraints
- * are ordered per dimension depth: the left hand side of the constraint matrix
- * is the identity) and will answer NO at the very first problem.
- * - d1 and d2 are the two domains to check for blocking,
- * - scattering is the linked list of all domains,
- * - scattdims is the total number of scattering dimentions.

- * cloog_domain_never_integral function:

- * function returns a boolean set to 1 if there is this kind of 'never true'
- * constraint inside a polyhedron, 0 otherwise.
- * - domain is the polyhedron to check,
- **
- * - November 28th 2001: first version.
- * - June 26th 2003: for iterators, more 'never true' constraints are found
- *                   (compare cholesky2 and vivien with a previous version),
- *                   checking for the parameters created (compare using vivien).
- * - June 28th 2003: Previously in loop.c and called
- *                   cloog_loop_simplify_nevertrue, now here !
- * - June 21rd 2005: Adaptation for GMP (based on S. Verdoolaege's version of
- *                   CLooG 0.12.1).
- * - October 14th 2005: Complete rewriting, not faster but code quite shorter.
