+This is the readme for installing the arm-miosix-eabi-gcc compiler,
+required to build Miosix.
+Currently this can only be done on Linux, even when compiling a
+compiler that will work for Windows.
+===================================================================
+
+
+Step 1
+------
+Copy this folder in a path without spaces, or compiling will fail.
+Example:
+/home/foo/temp OK
+/home/foo/directory with spaces/temp NO!!
+
+
+Step 2
+------
+Install the following dependencies:
+gcc, g++, make, ncurses, byacc, flex, texinfo, patch, tar, unzip, lzip, libelf perl libexpat
+
+For example, for Ubuntu/Kubuntu open a shell and type:
+sudo apt-get install gcc g++ make libncurses5-dev byacc flex texinfo patch tar unzip lzip libelf-dev perl libexpat1-dev
+
+While on Fedora:
+sudo yum intall gcc gcc-c++ make ncurses-devel byacc flex texinfo patch tar unzip lzip elfutils-libelf-devel perl libexpat-devel
+
+Note: these scripts require "sudo" unless you want to intall the compiler locally.
+If you use a distro like Fedora where sudo is not enabled by default, use "visudo" to enable sudo for your account.
+
+Step 3
+------
+Download the the required sources with the download script:
+
+./download.sh
+
+
+Step 4
+------
+After meeting these prerequisites, install:
+
+./install-script.sh -j`nproc`
+./cleanup.sh
+
+Both scripts will prompt for root password at some point. It is normal,
+since they need to write in /opt and /usr/bin.
+The cleanup script won't remove the compressed files downloaded with the
+download script. You might want to do so manually to save space on your disk.
+
+
+Step 5
+------
+Test the compiler by typing in a shell
+
+arm-miosix-eabi-gcc -v
+
+If you get something like
+
+bash: arm-miosix-eabi-gcc: command not found
+
+it means something did not work.
+
+
+Step 6
+------
+If required, also install OpenOCD for in circuit debugging.
+There are no scripts for doing that, since it is rather independent on the
+gcc version. On many distros it is also available thrugh package managers,
+for example on Ubuntu/Kubuntu you can install it with
+
+sudo apt-get install openocd
+
+Uninstalling the compiler
+=========================
+In case you need to uninstall the compiler (perhaps because you need to install
+an upgraded version as part of a new Miosix release) you can run the
+
+./uninstall.sh
+
+script.

+
+Add libsyscalls to the compiler and have gcc link with it be default by
+creating a specs file, remove stubs.c in newlib. Also, build newlib without
+libnosys and the other unused stub libraries.
+
+Reduce MAXNAMLEN in newlib from 1024 to 256, it is used to allocate a buffer
+on the stack in newlib/libc/posix/execvp.c
+
+Make ino_t a long long, to support, e.g, greater than 128GByte SD cards.
+Would require changes to the filesystems meant to support very large disks, such
+as fat32 too.
+
+Fix newlib so that the lstat syscall function prototype is made available,
+and maybe add prototype for _lstat_r too
+
+Update sys/lock.h make pthread_mutex_t compatible with future decisions to
+replace the custom list with IntrusiveList.
+Update _pthreadtypes.h removing the forward declaration of WaitingList and
+change pthread_cond_t to be two opaque pointers, comment that it should have
+a memory layout compatible with IntrusiveList.
+
+In libstdc++ header condition_variable the __wait_until_impl checks for timeout
+in this way:
+__gthread_cond_timedwait(&_M_cond, __lock.mutex()->native_handle(), &__ts);
+return (__clock_t::now() < __atime ? cv_status::no_timeout : cv_status::timeout);
+use the return value of pthread_cond_timedwait instead to optimize code
+
+In libstdc++ header condition_variable condition_variable::wait_for calls both clock_gettime(CLOCK_REALTIME... and clock_gettime(CLOCK_MONOTONIC...
+This is not needed as pthread_cond_timedwait in Miosix refuses to follow the
+(broken) standard on purpose and accepts the timeout directly in terms of
+CLOCK_MONOTONIC.
+defiitions are in time.h, CLOCK_REALTIME is 1, wile CLOCK_MONOTONIC is 4

+
+One way ticket to (autotools) hell and back.
+============================================
+
+A quick guide on how to make autotools work well enough in newlib to make patches.
+
+First of all the main part of the solution: autoreconf
+
+When adding new source files to a directory, use
+
+$ autoreconf --no-recursive
+$ find . -name autom4te.cache | xargs rm -rf
+
+The first command does the job. The --no-recursive option is to prevent it
+from trying to 'fix' configure files in all subdirectories. The second
+command removes all temporary files generated by the first.
+
+When adding a new directory with source files, you've got to add a configure.in
+and Makefile.am, by copying them from another directory and tweaking them.
+Then, go up one directory, open configure.in and add AC_CONFIG_SUBDIRS(newdir)
+where newdir is the new directory. After that, do a
+
+$ autoreconf
+$ find . -name autom4te.cache | xargs rm -rf
+
+Is this all? No, obviously. First of all, a small notice: never do an
+autoreconf in the top level directory. At most do an autoreconf in the
+newlib subdirectory.
+
+Then, the big trouble: autoconf and automake, the two tools behind all this
+autoconfiguration magic are neither forward nor backward compatible. If you
+try to autoreconf with a different version than the one used in newlib,
+they'll try to heavily modify each and every configure they come across,
+resulting in a diff from the previous version of several megabytes.
+
+So, you've got to download the exact version of autoconf and automake,
+make an autotools directory, copy the autoconf and automake of the exact
+version taken from the GNU website, and then
+
+$ wget https://ftpmirror.gnu.org/autoconf/autoconf-2.68.tar.bz2
+$ wget https://ftpmirror.gnu.org/automake/automake-1.11.6.tar.gz
+$ mkdir autobins && cd autobins
+$ PFX=`pwd`
+$ cd ..
+$ tar xjvf autoconf-2.68.tar.bz2
+$ cd autoconf-2.68
+$ ./configure --prefix=$PFX
+$ make
+$ make install
+$ cd ..
+$ tar xzvf automake-1.11.6.tar.gz
+$ cd automake-1.11.6
+$ ./configure --prefix=$PFX
+$ make
+$ make install
+$ cd ../autobins/share
+$ ln -s `pwd`/aclocal-1.11 aclocal
+
+Note that the last command is necessary because during installation an
+aclocal-1.11 directory is created, but the scripts expect an aclocal directory.
+Essentially, the make install of automake is broken, go figure...
+
+After that, before running autoreconf do an export PATH=<dir>:$PATH, where
+<dir> is the bin directory where autoconf and automake were installed.
+
+But wait, there's more fail!
+The old autotools scripts fail to run with the new perl interpreter...
+
+$ automake --version

+
+If it does so, fix it like this:

+# wrong, due to (1) the presence of 3 mutually incompatible instruction sets
+# (ARM, Thumb and Thumb2) and (2) the fact that the default compilation options
+# build for an extremely old configuration (-mcpu=arm7tdmi -marm) which produces
+# code not runnable on any modern ARM microcontroller CPU.
+# This line removes all the libraries not included in a multilib to prevent
+# GCC from producing broken binaries silently.
+# As a result, the use of compilation options not supported by the toolchain
+# will result in a link-time failure to find the libraries, hinting that

+# Cortex M3 because the first call to a libc function was a blx into ARM instruction

+
+ GNU GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+ The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users. We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors. 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
+them 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 prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. 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.
+
+ Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+ For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+ Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so. This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software. The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable. Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products. If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+ Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary. To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ TERMS AND CONDITIONS
+
+ 0. Definitions.
+
+ "This License" refers to version 3 of the GNU General Public License.
+
+ "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+ "The Program" refers to any copyrightable work licensed under this
+License. Each licensee is addressed as "you". "Licensees" and
+"recipients" may be individuals or organizations.
+
+ To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy. The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+ A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+ To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+ To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+ An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+ 1. Source Code.
+
+ The "source code" for a work means the preferred form of the work
+for making modifications to it. "Object code" means any non-source
+form of a work.
+
+ A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+ The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+ The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+ The Corresponding Source for a work in source code form is that
+same work.
+
+ 2. Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force. You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright. Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+the conditions stated below. Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+ 4. Conveying Verbatim Copies.
+
+ You may convey 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;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+ 5. Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+ a) The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.
+
+ b) The work must carry prominent notices stating that it is
+ released under this License and any conditions added under section
+ 7. This requirement modifies the requirement in section 4 to
+ "keep intact all notices".
+
+ c) You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable section 7
+ additional terms, to the whole of the work, and all its parts,
+ regardless of how they are packaged. This License gives no
+ permission to license the work in any other way, but it does not
+ invalidate such permission if you have separately received it.
+
+ d) If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your
+ work need not make them do so.
+
+ A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+ 6. Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+ a) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ b) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for as
+ long as you offer spare parts or customer support for that product
+ model, to give anyone who possesses the object code either (1) a
+ copy of the Corresponding Source for all the software in the
+ product that is covered by this License, on a durable physical
+ medium customarily used for software interchange, for a price no
+ more than your reasonable cost of physically performing this
+ conveying of source, or (2) access to copy the
+ Corresponding Source from a network server at no charge.
+
+ c) Convey individual copies of the object code with a copy of the
+ written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially, and
+ only if you received the object code with such an offer, in accord
+ with subsection 6b.
+
+ d) Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to
+ copy the object code is a network server, the Corresponding Source
+ may be on a different server (operated by you or a third party)
+ that supports equivalent copying facilities, provided you maintain
+ clear directions next to the object code saying where to find the
+ Corresponding Source. Regardless of what server hosts the
+ Corresponding Source, you remain obligated to ensure that it is
+ available for as long as needed to satisfy these requirements.
+
+ e) Convey the object code using peer-to-peer transmission, provided
+ you inform other peers where the object code and Corresponding
+ Source of the work are being offered to the general public at no
+ charge under subsection 6d.
+
+ A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+ A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling. In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage. For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product. A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+ "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source. The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed. Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+ 7. Additional Terms.
+
+ "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it. (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.) You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+ a) Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or
+
+ b) Requiring preservation of specified reasonable legal notices or
+ author attributions in that material or in the Appropriate Legal
+ Notices displayed by works containing it; or
+
+ c) Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ d) Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ e) Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ f) Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified versions of
+ it) with contractual assumptions of liability to the recipient, for
+ any liability that these contractual assumptions directly impose on
+ those licensors and authors.
+
+ All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+ 8. Termination.
+
+ You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+ 9. Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+run a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+ 10. Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.
+
+ An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+ 11. Patents.
+
+ A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's "contributor version".
+
+ A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+ In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients. "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+ A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License. You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+ 12. No Surrender of Others' Freedom.
+
+ If 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 convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all. For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+ 13. Use with the GNU Affero General Public License.
+
+ Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+ 14. Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions of
+the GNU 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 that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation. If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+ Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+ 15. Disclaimer of Warranty.
+
+ 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.
+
+ 16. Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+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.
+
+ 17. Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software: you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation, either version 3 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program. If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+ If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+ <program> Copyright (C) <year> <name of author>
+ This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+ You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+ The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library. If this is what you want to do, use the GNU Lesser General
+Public License instead of this License. But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+ This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+ 0. Additional Definitions.
+
+ As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+ "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+ An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+ A "Combined Work" is a work produced by combining or linking an
+Application with the Library. The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+ The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+ The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+ 1. Exception to Section 3 of the GNU GPL.
+
+ You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+ 2. Conveying Modified Versions.
+
+ If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+ a) under this License, provided that you make a good faith effort to
+ ensure that, in the event an Application does not supply the
+ function or data, the facility still operates, and performs
+ whatever part of its purpose remains meaningful, or
+
+ b) under the GNU GPL, with none of the additional permissions of
+ this License applicable to that copy.
+
+ 3. Object Code Incorporating Material from Library Header Files.
+
+ The object code form of an Application may incorporate material from
+a header file that is part of the Library. You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+ a) Give prominent notice with each copy of the object code that the
+ Library is used in it and that the Library and its use are
+ covered by this License.
+
+ b) Accompany the object code with a copy of the GNU GPL and this license
+ document.
+
+ 4. Combined Works.
+
+ You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+ a) Give prominent notice with each copy of the Combined Work that
+ the Library is used in it and that the Library and its use are
+ covered by this License.
+
+ b) Accompany the Combined Work with a copy of the GNU GPL and this license
+ document.
+
+ c) For a Combined Work that displays copyright notices during
+ execution, include the copyright notice for the Library among
+ these notices, as well as a reference directing the user to the
+ copies of the GNU GPL and this license document.
+
+ d) Do one of the following:
+
+ 0) Convey the Minimal Corresponding Source under the terms of this
+ License, and the Corresponding Application Code in a form
+ suitable for, and under terms that permit, the user to
+ recombine or relink the Application with a modified version of
+ the Linked Version to produce a modified Combined Work, in the
+ manner specified by section 6 of the GNU GPL for conveying
+ Corresponding Source.
+
+ 1) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (a) uses at run time
+ a copy of the Library already present on the user's computer
+ system, and (b) will operate properly with a modified version
+ of the Library that is interface-compatible with the Linked
+ Version.
+
+ e) Provide Installation Information, but only if you would otherwise
+ be required to provide such information under section 6 of the
+ GNU GPL, and only to the extent that such information is
+ necessary to install and execute a modified version of the
+ Combined Work produced by recombining or relinking the
+ Application with a modified version of the Linked Version. (If
+ you use option 4d0, the Installation Information must accompany
+ the Minimal Corresponding Source and Corresponding Application
+ Code. If you use option 4d1, you must provide the Installation
+ Information in the manner specified by section 6 of the GNU GPL
+ for conveying Corresponding Source.)
+
+ 5. Combined Libraries.
+
+ 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 that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+ a) Accompany the combined library with a copy of the same work based
+ on the Library, uncombined with any other library facilities,
+ conveyed under the terms of this License.
+
+ b) Give prominent notice with the combined library that part of it
+ is a work based on the Library, and explaining where to find the
+ accompanying uncombined form of the same work.
+
+ 6. Revised Versions of the GNU Lesser General Public License.
+
+ The Free Software Foundation may publish revised and/or new versions
+of the GNU 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 as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+ If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+ GNU GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+ The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users. We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors. 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
+them 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 prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. 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.
+
+ Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+ For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+ Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so. This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software. The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable. Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products. If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+ Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary. To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ TERMS AND CONDITIONS
+
+ 0. Definitions.
+
+ "This License" refers to version 3 of the GNU General Public License.
+
+ "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+ "The Program" refers to any copyrightable work licensed under this
+License. Each licensee is addressed as "you". "Licensees" and
+"recipients" may be individuals or organizations.
+
+ To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy. The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+ A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+ To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+ To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+ An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+ 1. Source Code.
+
+ The "source code" for a work means the preferred form of the work
+for making modifications to it. "Object code" means any non-source
+form of a work.
+
+ A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+ The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+ The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+ The Corresponding Source for a work in source code form is that
+same work.
+
+ 2. Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force. You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright. Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+the conditions stated below. Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+ 4. Conveying Verbatim Copies.
+
+ You may convey 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;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+ 5. Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+ a) The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.
+
+ b) The work must carry prominent notices stating that it is
+ released under this License and any conditions added under section
+ 7. This requirement modifies the requirement in section 4 to
+ "keep intact all notices".
+
+ c) You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable section 7
+ additional terms, to the whole of the work, and all its parts,
+ regardless of how they are packaged. This License gives no
+ permission to license the work in any other way, but it does not
+ invalidate such permission if you have separately received it.
+
+ d) If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your
+ work need not make them do so.
+
+ A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+ 6. Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+ a) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ b) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for as
+ long as you offer spare parts or customer support for that product
+ model, to give anyone who possesses the object code either (1) a
+ copy of the Corresponding Source for all the software in the
+ product that is covered by this License, on a durable physical
+ medium customarily used for software interchange, for a price no
+ more than your reasonable cost of physically performing this
+ conveying of source, or (2) access to copy the
+ Corresponding Source from a network server at no charge.
+
+ c) Convey individual copies of the object code with a copy of the
+ written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially, and
+ only if you received the object code with such an offer, in accord
+ with subsection 6b.
+
+ d) Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to
+ copy the object code is a network server, the Corresponding Source
+ may be on a different server (operated by you or a third party)
+ that supports equivalent copying facilities, provided you maintain
+ clear directions next to the object code saying where to find the
+ Corresponding Source. Regardless of what server hosts the
+ Corresponding Source, you remain obligated to ensure that it is
+ available for as long as needed to satisfy these requirements.
+
+ e) Convey the object code using peer-to-peer transmission, provided
+ you inform other peers where the object code and Corresponding
+ Source of the work are being offered to the general public at no
+ charge under subsection 6d.
+
+ A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+ A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling. In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage. For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product. A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+ "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source. The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed. Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+ 7. Additional Terms.
+
+ "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it. (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.) You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+ a) Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or
+
+ b) Requiring preservation of specified reasonable legal notices or
+ author attributions in that material or in the Appropriate Legal
+ Notices displayed by works containing it; or
+
+ c) Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ d) Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ e) Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ f) Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified versions of
+ it) with contractual assumptions of liability to the recipient, for
+ any liability that these contractual assumptions directly impose on
+ those licensors and authors.
+
+ All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+ 8. Termination.
+
+ You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+ 9. Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+run a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+ 10. Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.
+
+ An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+ 11. Patents.
+
+ A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's "contributor version".
+
+ A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+ In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients. "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+ A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License. You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+ 12. No Surrender of Others' Freedom.
+
+ If 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 convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all. For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+ 13. Use with the GNU Affero General Public License.
+
+ Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+ 14. Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions of
+the GNU 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 that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation. If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+ Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+ 15. Disclaimer of Warranty.
+
+ 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.
+
+ 16. Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+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.
+
+ 17. Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software: you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation, either version 3 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program. If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+ If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+ <program> Copyright (C) <year> <name of author>
+ This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+ You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+ The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library. If this is what you want to do, use the GNU Lesser General
+Public License instead of this License. But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+ This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+ 0. Additional Definitions.
+
+ As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+ "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+ An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+ A "Combined Work" is a work produced by combining or linking an
+Application with the Library. The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+ The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+ The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+ 1. Exception to Section 3 of the GNU GPL.
+
+ You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+ 2. Conveying Modified Versions.
+
+ If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+ a) under this License, provided that you make a good faith effort to
+ ensure that, in the event an Application does not supply the
+ function or data, the facility still operates, and performs
+ whatever part of its purpose remains meaningful, or
+
+ b) under the GNU GPL, with none of the additional permissions of
+ this License applicable to that copy.
+
+ 3. Object Code Incorporating Material from Library Header Files.
+
+ The object code form of an Application may incorporate material from
+a header file that is part of the Library. You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+ a) Give prominent notice with each copy of the object code that the
+ Library is used in it and that the Library and its use are
+ covered by this License.
+
+ b) Accompany the object code with a copy of the GNU GPL and this license
+ document.
+
+ 4. Combined Works.
+
+ You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+ a) Give prominent notice with each copy of the Combined Work that
+ the Library is used in it and that the Library and its use are
+ covered by this License.
+
+ b) Accompany the Combined Work with a copy of the GNU GPL and this license
+ document.
+
+ c) For a Combined Work that displays copyright notices during
+ execution, include the copyright notice for the Library among
+ these notices, as well as a reference directing the user to the
+ copies of the GNU GPL and this license document.
+
+ d) Do one of the following:
+
+ 0) Convey the Minimal Corresponding Source under the terms of this
+ License, and the Corresponding Application Code in a form
+ suitable for, and under terms that permit, the user to
+ recombine or relink the Application with a modified version of
+ the Linked Version to produce a modified Combined Work, in the
+ manner specified by section 6 of the GNU GPL for conveying
+ Corresponding Source.
+
+ 1) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (a) uses at run time
+ a copy of the Library already present on the user's computer
+ system, and (b) will operate properly with a modified version
+ of the Library that is interface-compatible with the Linked
+ Version.
+
+ e) Provide Installation Information, but only if you would otherwise
+ be required to provide such information under section 6 of the
+ GNU GPL, and only to the extent that such information is
+ necessary to install and execute a modified version of the
+ Combined Work produced by recombining or relinking the
+ Application with a modified version of the Linked Version. (If
+ you use option 4d0, the Installation Information must accompany
+ the Minimal Corresponding Source and Corresponding Application
+ Code. If you use option 4d1, you must provide the Installation
+ Information in the manner specified by section 6 of the GNU GPL
+ for conveying Corresponding Source.)
+
+ 5. Combined Libraries.
+
+ 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 that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+ a) Accompany the combined library with a copy of the same work based
+ on the Library, uncombined with any other library facilities,
+ conveyed under the terms of this License.
+
+ b) Give prominent notice with the combined library that part of it
+ is a work based on the Library, and explaining where to find the
+ accompanying uncombined form of the same work.
+
+ 6. Revised Versions of the GNU Lesser General Public License.
+
+ The Free Software Foundation may publish revised and/or new versions
+of the GNU 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 as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+ If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+Rationale for gcc patch
+-----------------------
+
+This patch does the following:
+
+1) It modifies the config/gthr.m4 and libgcc/configure files to add
+ gthr-miosix.h to the build system.
+
+2) It modifies gcc/config.gcc to add the miosix-eabi.h file and t-arm-miosix to
+ the build system.
+
+3) It modifies gcc/configure and gcc/configure.ac to accept the parameter
+ --enable-threads=miosix
+
+4) It adds gcc/config/arm/miosix-eabi.h which defines the builtin _MIOSIX and
+ the miosix patch version.
+
+5) It adds gcc/config/arm/t-arm-miosix to enable multilibs for
+ fpie/msingle-pic-base to implement processes. It also enables multilibs for
+ ARM architecture variants relevant for microcontrollers.
+
+6) Given that Miosix does not have a thread local storage API, but it is
+ required in a couple of places related to C++ exception handling
+ (that is, gcc/unwind-sjlj.c and libsupc++/eh_globals.cc), those files have
+ been modified removing functions to get/set the thread-local variables.
+ Those functions are now implemented within Miosix, in kernel/syscalls.cpp
+
+7) It adds the gcc/gthr-miosix.h specifying the miosix thread model, basically
+ telling the compiler that threadsafe code is required and pointing it to
+ the routines it needs to do so (standard posix routines). Without this
+ modification, arm-miosix-eabi-gcc -v would report "Thread model: single"
+ and generate thread unsafe code.
+
+8) The thread safe initialization of C++ static objects can be implemented
+ more efficiently using the Miosix API rather than the POSIX one, so the
+ functions __cxa_guard_[acquire|release|abort] have been removed from
+ libsupc++/guard.cc and implemented in miosix/kernel/syscalls.cpp
+
+9) It reduces the size of the emergency buffer in
+ libstdc++-v3/libsupc++/eh_alloc.cc, which is used for allocating the
+ std::bad_alloc exception that operator new should throw when the heap is
+ full. By default it is set to a conservative value that is too large when
+ compared with the RAM size of microcontrollers.
+
+10) It makes the verbose terminate handler a weak symbol to save code size.
+
+11) It adds __attribute__((weak)) to some functions that pull in exception
+ support to make them overridable by miosix when compiling without exceptions
+ to minimize code size. The only ones which are not made weak are:
+ - ios_failure: already large code size, so might as well not disable exceptions
+ - regex: same as above
+ - occurrences of _GLIBCXX_THROW_OR_ABORT in headers. Don't know how to fix
+ those, if they are ever used inside a .cc file within libstdc++ itself.
+
+12) It moves some functions from a .cc file within libstdc++ to the header file,
+ as when libstdc++ is compiled, exceptions are enabled. This code then pulls
+ in exception support (and its code size penalty) even when Miosix is built
+ with exceptions disabled. string, condition_variable and thread have
+ been patched to avoid this. For string, removing template instantiation
+ prevention code for basic_string was needed to generate non-exception code
+ that is preferentially linked instead of the one in libstdc++ forcedly
+ instantiated in libstdc++.
+
+NOTES
+-----
+
+Atomicity of libstdc++
+----------------------
+from objdir/arm-miosix-eabi/<arch>/libstdc++-v3/config.log
+ ARM CM0 CM3 CM4 CM7
+atomic builtins for bool - - Y Y Y
+atomic builtins for short - - Y Y Y
+atomic builtins for int - - Y Y Y
+atomic builtins for long long - - - - -
+lock policy for shared_ptr F F Y* Y* Y*
+* configure:15883: result: atomic
+Note that:
+- atomic_store still uses mutex anyway, see bits/shared_ptr_atomic.h
+
+Autotools issue
+---------------
+Some configure checks fail because in order to check for the presence of a
+particular function, a sample C program is compiled AND LINKED. Now, the
+GCC for miosix is meant to work if linked to libmiosix.a which isn't there yet,
+so code depending on syscalls causes "undefined reference" link failures.
+Do check the output of configure (configure.log) for check failures and
+add stubs to newlib accordingly.
+Note: look for configure.log in objdir/arm-miosix-eabi subdirectories,
+which curently are libatomic, libgcc, libquadmath and libstdc++-v3.
+The one that does more syscall-dependent configure checks is libstdc++
+
+Checks
+------
+thread_local is not supported, check that an example with thread_local produces
+compile-time errors to avoid giving the false impression that it works.
+
+Types to watch out
+------------------
+Some unexported types are copy-pasted in the kernel, and need to be kept consistent

+sizeof(__cxa_refcounted_exception) 128
+sizeof(std::bad_alloc) 4
+sizeof(std::logic_error) 8
+
+While on other archs is (commenting #ifdef __ARM_EABI_UNWINDER__ part in unwind-cxx.h)
+sizeof(_Unwind_Exception) 88
+sizeof(_Atomic_word) 4
+sizeof(__cxa_exception) 136
+sizeof(__cxa_refcounted_exception) 144
+sizeof(std::bad_alloc) 4
+sizeof(std::logic_error) 8
+
+Thus allocating bad_alloc takes 132Bytes on ARM, and 148Bytes on other archs.
+
+It is recomended to leave some space just in case a different exception is
+thrown, like logic_error or runtime_error and there is no heap to allocate it.
+By seeing stdexcept and stdexcept.cc these classes only contain a string object,
+and sizeof(logic_error) returns 8 bytes (4=vptr 4=string).
+
+Note Jul 5, 2010.
+A testcase started to fail, JTAG debugging found that a bad_alloc was allocated
+that required 132Bytes. Expanding EMERGENCY_OBJ_SIZE to 160 bytes (128+32) to leave
+some margin.
+Note Sep 1, 2019.
+Apparently, nothing changed in 9 years, as bad_alloc still requires 132Bytes.
+
+Conclusion:
+Looks like EMERGENCY_OBJ_SIZE can be shrinked from 512 to 160bytes, for 32bit systems.
+For EMRGENCY_OBJ_COUNT, 3 is good.

+# Multilib configuration with config file fragments in GCC
+
+Even though the documentation in https://gcc.gnu.org/onlinedocs/gccint/Target-Fragment.html
+is fairly comprehensive about how config file fragments work, it is missing
+a high-level overview of what is happening and leaves out important details,
+which might make the process of updating these files a bit baffling.
+
+The config file fragments to run are selected by the config.gcc shell script,
+depending on the specified target triple, matched via shell script globs.
+The list of fragments is stored in the tmake_file environment variable, which
+through the magic of autoconf/automake gets copied in the materialized
+Makefile, where they are included just before the declaration of the recipes
+related to target-dependent files. Therefore, these "config" file fragments are
+actually Makefile includes, and do not actually run at config time. Whatever.
+
+The config fragments set the following variables related to multilib:
+
+ - `MULTILIB_OPTIONS`, `MULTILIB_DIRNAMES`: base set of multilibs
+ - `MULTILIB_EXCEPTIONS`: blacklist to be applied to the base set
+ - `MULTILIB_REQUIRED`: whitelist to be applied to the base set after the blacklist
+ - `MULTILIB_MATCHES`: specifies aliases for single options
+ - `MULTILIB_REUSE`: specifies aliases for single option combinations
+
+These variables are processed by a Python script called `genmultilib`, which
+in turn produces a header file called `multilib.h` which is then included
+by the code of GCC. This mechanism effectively "bakes" the multilib directory
+structure in the GCC executable.
+
+## Multilib option expansion
+
+The `MULTILIB_OPTIONS` variable is basically interpreted as a list of
+sets, where the number of sets is defined by the number of options separated by
+spaces, and slashes (/) separe each item in the set. Each set also implicitly
+includes the empty string (for the case in which the option is not specified).
+
+Therefore if
+
+```
+MULTILIB_OPTIONS=mthumb march=armv6s-m/march=armv7-m/march=armv7e-m mfloat-abi=hard/mfloat-abi=softfp
+```
+
+then there are 3 sets with size 2, 4, 3 respectively:
+
+```
+"" "" ""
+"mthumb" "march=armv6s-m" "mfloat-abi=hard"
+ "march=armv7-m" "mfloat-abi=softfp"
+ "march=armv7e-m"
+```
+
+The multilib list is generated by cartesian product of the sets, resulting in:
+
+```
+"","",""
+"","","mfloat-abi=hard"
+"","","mfloat-abi=softfp"
+"","march=armv6s-m",""
+"","march=armv6s-m","mfloat-abi=hard"
+"","march=armv6s-m","mfloat-abi=softfp"
+"","march=armv7-m",""
+"","march=armv7-m","mfloat-abi=hard"
+"","march=armv7-m","mfloat-abi=softfp"
+"","march=armv7e-m",""
+"","march=armv7e-m","mfloat-abi=hard"
+"","march=armv7e-m","mfloat-abi=softfp"
+"mthumb","",""
+"mthumb","","mfloat-abi=hard"
+"mthumb","","mfloat-abi=softfp"
+"mthumb","march=armv6s-m",""
+"mthumb","march=armv6s-m","mfloat-abi=hard"
+"mthumb","march=armv6s-m","mfloat-abi=softfp"
+"mthumb","march=armv7-m",""
+"mthumb","march=armv7-m","mfloat-abi=hard"
+"mthumb","march=armv7-m","mfloat-abi=softfp"
+"mthumb","march=armv7e-m",""
+"mthumb","march=armv7e-m","mfloat-abi=hard"
+"mthumb","march=armv7e-m","mfloat-abi=softfp"
+```
+
+And now you know why this way of deciding which multilibs to build wasn't
+exactly the best one... and they introduced `MULTILIB_EXCEPTIONS`,
+`MULTILIB_REQUIRED`, `MULTILIB_MATCHES` and `MULTILIB_REUSE` to patch it up.
+All these variables take the list above and modify it. `MULTILIB_REQUIRED`
+modifies the combinations GCC build time, while the others are implemented
+at GCC runtime.
+
+The `genmultilib` script flattens the sets even more, by repeating all options
+that were *not* chosen, prefixed by a "!", producing basically an (inefficient)
+one-hot encoding of the above. Therefore the list above becomes:
+
+```
+"!mthumb !march=armv6s-m !march=armv7-m !march=armv7e-m !mfloat-abi=hard !mfloat-abi=softfp"
+"!mthumb !march=armv6s-m !march=armv7-m !march=armv7e-m mfloat-abi=hard !mfloat-abi=softfp"
+"!mthumb !march=armv6s-m !march=armv7-m !march=armv7e-m !mfloat-abi=hard mfloat-abi=softfp"
+"!mthumb march=armv6s-m !march=armv7-m !march=armv7e-m !mfloat-abi=hard !mfloat-abi=softfp"
+"!mthumb march=armv6s-m !march=armv7-m !march=armv7e-m mfloat-abi=hard !mfloat-abi=softfp"
+"!mthumb march=armv6s-m !march=armv7-m !march=armv7e-m !mfloat-abi=hard mfloat-abi=softfp"
+...
+```
+
+You get the idea...
+
+## Multilib selection process
+
+When choosing a multilib, GCC first normalizes (in a target-dependent way)
+the command line options related to the architecture to a certain degree
+(mainly adds -march=... if it has been implied by a more complex sequence of
+options, and also adds any default option if it has not been specifically
+overridden) and then picks the multilib directory via the `set_multilib_dir()`
+function (in gcc/gcc.c).
+
+This function first check if there is an exclusion (`MULTILIB_EXCEPTIONS`)
+that matches all the specified arguments. In that case it quits immediately,
+which results in not choosing any multilib.
+Otherwise, it checks every available multilib and alias (`MULTILIB_REUSE`)
+for a match with the given options. Options in the multilib specification and
+the command line are compared via plain old string comparison (!).
+The algorithm looks like this, in pseudocode (assuming I didn't read it wrong,
+the original implementation of the logic is unnecessarily convoluted):
+
+```
+for combination in multilibs:
+ ok = true
+ for option in combination:
+ # gcc/gcc.c:8944 (gcc 9.2.0)
+ if option was specified because it's a default:
+ continue
+ # gcc/gcc.c:8930 (gcc 9.2.0)
+ in_cmd_line = option was specified in the command line
+ should_be_in_cmd_line = option is specified for this multilib (not prefixed with !)
+ if in_cmd_line != should_be_in_cmd_line:
+ ok = false
+ break
+ # gcc/gcc.c:8951 (gcc 9.2.0)
+ if ok:
+ return directory of this combination
+# no multilib found
+return root lib directory
+```
+
+In other words, options that are not contemplated by the multilib configuration
+are ignored. Amongst the options contemplated, a multilib matches if all
+non-default options given to gcc (after normalization) match exactly with the
+ones that were enabled for that multilib.
+
+Note that options set as default via defines (for example `TARGET_DEFAULT_FLOAT_ABI`)
+do NOT count as a default option for the logic above, as these defaults never
+appear as argument strings in a gcc internal command line. I leave any comment
+to the reader.
+
+## Can I have two options that always appear together be associated with one directory level instead of two?
+
+Example: `-fpie -msingle-pic-base` are either both enabled or both disabled for
+Miosix multilibs. We want to use a single directory level `processes` for that
+pair of options instead of two levels.
+
+Putting the two options in quotes will never work because the quotes will
+be inconsistently expanded by the various scripts. I didn't even try this
+approach because it sounds so hopeless. (if you have one day to waste you can
+try it out!)
+
+What I tried is using "." for one of the directories like this:
+
+```
+MULTILIB_OPTIONS += fpie msingle-pic-base
+MULTILIB_DIRNAMES += processes .
+```
+
+which incredibly is fine for GCC... but not for newlib because for some
+(probably Makefile-related) reason at one point it counts the number of
+path components and replaces them with ".." to get to the root and... well yeah,
+you can guess what happens :(
+
+So the answer is no, you can't do this. That's sad.

+# Notes on the patch to support processes in Miosix
+
+TODO: Intro, pie, single-pic-base, no fixed offset between .text/.rodata and .got/.data/.bss, the basic stuff of how Miosix processes work.
+
+TODO: Comment the changes that were introduced in 4.7.3 and their limitations (processes couldn't use standard libraries as malloc and everything that used it was broken), as what comes next is a delta compared to it.
+
+NOTE: Most of this document contains addresses from debugging sessions done when DATA_BASE, or the base address of the data segment in a Miosix process before being dynamically relocated, is 0x10000000. This was later changed to 0x40000000, so watch out if some address seems strange.
+
+
+
+## The problem with extern const (FIXED)
+
+In processes compiled with GCC 4.7.3:
+
+- stuff in .data are accessed from the GOT, which is OK
+- strings in .rodata are accessed PC-relative, which is OK
+- consts in .rodata are accessed from the GOT, which is WRONG! (more on that later when pointer are involved, though)
+
+Here's an example:
+
+```
+extern const int aRodata;
+extern int aData;
+const char str[]="Hello world\n";
+
+int get1() { return aRodata; }
+int get2() { return aData; }
+const char *get3() { return str; }
+```
+
+used to compile as:
+
+```
+get1:
+ ldr r3, .L3
+ ldr r3, [r9, r3]
+ ldr r0, [r3]
+ bx lr
+
+get2:
+ ldr r3, .L6
+ ldr r3, [r9, r3]
+ ldr r0, [r3]
+ bx lr
+
+
+get3:
+ ldr r0, .L9
+.LPIC0:
+ add r0, pc
+ bx lr
+```
+
+`get1()` is the wrong one, of course.
+
+(Compiled with `arm-miosix-eabi-gcc -mcpu=cortex-m3 -mthumb -mfix-cortex-m3-ldrd -fpie -msingle-pic-base -O2 -S processes.c`).
+
+What usually masks the issue is constant folding. Unless it's an extern const the value gets folded and the problem does not arise.
+
+Solution:
+the previous patch relied on a GCC function, `decl_readonly_section()` to check whether the global variable to be loaded is const or not, but that function missed a few cases, so a dedicated function, the `miosix_processes_ref_demux()` function was added in `arm.c`. This new function handles the corner cases better, and also allows to fix some of the next issues.
+
+
+
+
+## Why malloc failed (FIXED)
+
+`malloc()` uses a convoluted global array of pointers with an initializer list which makes them point inside the array itself. For a long time this was thought to confuse the codegen/relocations/whatever, somehow.
+
+Segfault was at address 0xf2 of this code:
+
+```
+ e6: 2318 movs r3, #24
+ e8: f8df 2538 ldr.w r2, [pc, #1336] ; 624 <_malloc_r+0x55c>
+ ec: f859 6002 ldr.w r6, [r9, r2]
+ f0: 4433 add r3, r6
+newlib-3.1.0/newlib/libc/stdlib/mallocr.c:2378
+ f2: 685c ldr r4, [r3, #4]
+```
+
+But replicating similar code that referenced the same convolute array, `__malloc_av_` did not cause segfaults.
+
+An objdump of `main.o` found at the end of func:
+
+```
+ 44: R_ARM_GOT32 __malloc_av_
+```
+
+While an objdump of `lib_a-mallocr.o` at the end of `malloc_r`:
+
+```
+ 55c: R_ARM_GOTOFF32 .LANCHOR0
+ 560: R_ARM_GOTOFF32 .LANCHOR1
+ 564: R_ARM_GOTOFF32 .LANCHOR2
+```
+
+Page 208 of linkers and loaders explains the difference between GOT32 and GOTOFF, and GOTOFF relaocations only work if the gap between .text and .got is known, which is not.
+
+Turns out the issue is unrelated to the convolute array of malloc, a much simpler test case that triggers the issue causing GOTOFF relocations is:
+
+```
+int *ptr = { 0 };
+int *get6()
+{
+ return ptr;
+}
+```
+
+Solution: comment out the part that generates GOTOFF relocations in the `arm_assemble_integer()` function in `arm.c`. In Miosix processes GOTOFF relocations should never appear.
+
+
+
+
+## The problem with const pointers (FIXED)
+
+Accessing `_GLOBAL_REENT` in newlib segfaults, such as in this function:
+
+```
+struct _reent *__getreent()
+{
+ return _GLOBAL_REENT;
+}
+
+__getreent():
+ a78: 4b01 ldr r3, [pc, #4] ; (a80 <__getreent+0x8>)
+ a7a: 447b add r3, pc
+ a7c: 6818 ldr r0, [r3, #0]
+ a7e: 4770 bx lr
+```
+
+Now, `_GLOBAL_REENT` is declared as:
+
+```
+// sys/reent.h
+extern struct _reent *const _global_impure_ptr;
+#define _GLOBAL_REENT _global_impure_ptr
+```
+
+and defined as:
+
+```
+// impure.c
+static struct _reent impure_data = _REENT_INIT(impure_data);
+struct _reent *_impure_ptr = &impure_data;
+struct _reent *const _global_impure_ptr = &impure_data;
+```
+
+At first it was believed that the issue is with the constness of pointer being more complex than normal variables, as we need not confuse the constness of the thing pointed to from the constness of the pointer itself.
+
+However, further investigation found out the const patch works in this case too:
+
+```
+extern const int * cptr;
+const int *get() { return cptr; }

+```
+
+Basically, `extern const int * cptr;` is a non-const pointer, so it ends up in .data, and is accessed from the GOT, which is OK, and `extern int * const cptr;` is a const pointer which should end up in .rodata, so is accessed PC-relative, which seems good. In general, when deciding whether to use GOT or PC-relative addressing to get a pointer we are concerned about how to acccess the pointer itself, not what it points to (accessing what it points to is trivial and uniform, as you just need to dereference it in all cases).
+
+Although it seems reasonable to assume a const pointer ends up in .rodata just like any otheer const, it's also wrong.
+
+It looks that to know whether a pointer ends up in .rodata or not you can't just look at its **declaration**, you have to look at is **definition**, see for yourself:
+
+```
+extern int aData;
+int * const ptr1=0;
+int * const ptr2=&aData;
+
+ .section .rodata
+ptr1:
+ .space 4
+
+ .section .data.rel.ro,"aw"
+ptr2:
+ .word aData
+```
+If the const pointer is defined as pointing to another variable, it needs to be relocated. That is, the content of the memory cell of the pointer itself isn't known till run-time, because the address of the variable it should point to isn't known. But relocations in .rodata can't happen, as its... readonly, so the constant pointer gets promoted to another section that is in RAM so the relocation can take place.
+
+The implemented fix requres a compromise: in the general case we can't see the pointer definition, as it may be in another translation unit. Thus, we assume that all pointers will need a relocation, and thus we access all pointers (or all complex data structures that may contain pointers, using the `contains_pointers_p()` function of GCC) and use GOT addressing for those.
+
+At first, it was believed that to make this work, we need to actually move them into RAM to make the relocation work.
+
+This patch fragment of `categorize_decl_for_section()` in `varasm.c` did exactly that.

+
+But it was found out that this patch failed to work when arrays were concerned.
+An example found in newlib that caused segfaults is in `dtoa.c` when accessing the `tinytens` and `bigtens` arrays defined in `mprec.c`.
+
+A simpler testcase can be made but it requires two translation units to prevent folding masking the issue.
+
+```
+// stuff.h
+extern const int ptr[];
+
+// stuff.c
+const int ptr[] = { 0x12345678 };
+
+// main.c
+// do something that accesses ptr
+
+```
+
+This example and the one in libc do cause the appearance of GOT entries which point to .rodata.
+
+Instead of chasing every case where we need to promote something from .rodata to .data, a patch was made in the OS kernel relocation code:
+if the relocation target address is not greater than DATA_BASE (which was 0x10000000 and later as part of these patch was changed to 0x40000000), it means that the relocation points to .rodata, and in that case the relocation is done starting from the CODE base address, not from the RAM base address.
+
+This fix made obsolete the idea of forcedly promoting pointer-containing data structures to RAM, so the `varasm.c` patch above was removed. This choice saves RAM, as now
+
+* pointer containing global data structures that need no relocation stay in .rodata (saving RAM) but are accessed from the GOT anyway as-if they were in RAM. The OS relocation code patch makes this work, and there is a small but unavoidable RAM size penalty for the GOT entries, which is however unavoidable as we need an uniform way to access them without seeing their definition.
+
+* pointer containing global data structures that do need relocations get promoted to RAM (necessary) and are accessed from the GOT (necessary, as being in RAM, PC-relative addressing won't work).
+
+TL;DR: in pointer containing data structures, sometimes we go through the GOT even if the data structure we're accessing is in .rodata. This slight inefficiency is however necessary for uniformity in accessing said data structures.
+
+
+
+
+## The problem with vtables (FIXED)
+
+An example with `cout << "Hello world" << endl;` fails with a segfault during static construction of the cout object. The problem arises during a `dynamic_cast`.
+
+```
+Process 1 terminated due to a fault
+* Code base address was 0x64017268
+* Data base address was 0x64100000
+* MPU region 6 0x64000000-0x64100000 r-x
+* MPU region 7 0x64100000-0x64104000 rw-
+* Attempted data access @ 0x74017818 (PC was 0x6403a610)
+Process 1 terminated
+Process segfaulted
+```
+
+Trying to understand where the wrong address goes `0x74017818 - 0x64017268 = 0x100005b0` and this address points to
+
+```
+ .data.rel.ro._ZTVSt5ctypeIcE
+ 0x00000000100005b0 0x30 libstdc++.a(ctype.o)
+ 0x00000000100005b0 _ZTVSt5ctypeIcE
+```
+
+and `_ZTVSt5ctypeIcE` is `vtable for std::ctype<char>`.
+
+Further testing with a simpler program fails in the same way
+
+```
+#include <cstdio>
+
+class Base
+{
+public:
+ virtual void print() const { puts("I'm Base"); }
+ virtual ~Base() {}
+};
+
+class Derived : public Base
+{
+public:
+ virtual void print() const { puts("I'm Derived"); }
+};
+
+void __attribute__((noinline)) call(Base *base)
+{
+ base->print();
+}
+
+Base *__attribute__((noinline)) mkbase()
+{
+ return new Base;
+}
+
+Derived *__attribute__((noinline)) mkderived()
+{
+ return new Derived;
+}
+
+int main()
+{
+ volatile int i=0;
+ Base *base = i==0 ? mkderived() : mkbase();
+ call(base);
+ delete base;
+}
+```
+
+It appears that the issue occurs in the constructor
+
+```
+0000ead4 <_Z9mkderivedv>:
+_Z9mkderivedv():
+ ead4: b508 push {r3, lr}

+```
+
+where the object memory is allocated, and the vptr is set to point to the vtable using PC-relative addressing even though the vtable is in RAM, as it's in .dat.rel.ro
+
+The vtable is considered const even though it contains pointers becauses it passes the `decl_readonly_section` check, which is done before the `contains_pointers_p` check.

+```
+
+As the vtable contains constant pointers (that need to be initialized to within .text to point to the member functions), relocations need to be done.
+The solution is to move the `contains_pointers_p` check first.
+
+
+
+
+## The problem with R_ARM_REL32 relocations (FIXED)
+
+Trying to compile C++ programs that do not use exceptions causes compilation to fail. An example as simple as this triggers the issue:
+
+```
+#include <cstdio>
+
+using namespace std;
+
+int main()
+{
+ printf("Hello world\n");
+ return 0;
+}
+```
+
+which fails with:
+
+```
+ld: libgcc.a(unwind-arm.o): relocation R_ARM_REL32 against external or undefined symbol `__cxa_call_unexpected' can not be used when making a PIE executable; recompile with -fPIC
+libgcc.a(unwind-arm.o): in function `__gnu_unwind_pr_common':
+unwind-arm-common.inc:824:(.text+0x744): dangerous relocation: unsupported relocation
+```
+
+Compiling with `-fno-exceptions` or adding code that throws/catches exceptions fixes the issue, but code that does not throw should not fail to compile.
+
+The problem is in `unwind-arm-common.inc` which declares a few functions prototypes as `__attribute__((weak))` that it then calls. Moreover, in one case it checkes whether the pointer to the `__gnu_Unwind_Find_exidix` function is not null, to see if the function exists in the (runtime) linked binary.
+
+The fix consists in patching `unwind-arm-common.inc` so that the function prototypes are no longer weak, and removing completely the check **and** then call to `__gnu_Unwind_Find_exidix` as it's not needed in Miosix.
+
+
+
+
+## The problem with unwinding exception tables (FIXED)
+
+A simple program that throws an exception would segfault
+
+```
+#include <cstdio>
+
+void __attribute__((noinline)) f()
+{
+ throw 1;
+}
+
+int main() try {
+ puts("in");
+ f();
+ puts("out");
+ return 0;
+} catch(int& e) {
+ puts("exc");
+ return e;
+}
+```
+
+in `__cxa_type_match`
+
+```
+0000eee4 <__cxa_type_match>:
+[...]
+gcc-9.2.0/libstdc++-v3/libsupc++/eh_arm.cc:86
+ ef08: 6823 ldr r3, [r4, #0]
+```
+
+The fault happens when dereferencing a pointer, but the pointer does not get computed in this function, but passed as a parameter.
+The caller is `__gxx_personality_v0`
+
+```
+line 576 of eh_personality.cc
+
+ while (1)
+ {
+ p = action_record;
+ p = read_sleb128 (p, &ar_filter);
+ read_sleb128 (p, &ar_disp);
+
+ if (ar_filter == 0)
+ {
+ // Zero filter values are cleanups.
+ saw_cleanup = true;
+ }
+ else if (ar_filter > 0)
+ {
+ // Positive filter values are handlers.
+ catch_type = get_ttype_entry (&info, ar_filter);
+
+ // Null catch type is a catch-all handler; we can catch foreign
+ // exceptions with this. Otherwise we must match types.
+ if (! catch_type
+ || (throw_type
+ && get_adjusted_ptr (catch_type, throw_type,
+ &thrown_ptr)))
+```
+
+The `get_adjusted_ptr` is a macro to the `__cxa_type_match` code that is faulting.
+The corrupted variable is `catch_type`, and is returned by `get_ttype_entry`, which in turn gets it by calling `read_encoded_value_with_base` in `libgcc/unwind-pe.h`.
+
+The `read_encoded_value_with_base` is called with the following parameters:
+```
+unsigned char encoding = 0x10
+_Unwind_Ptr base = 0
+const unsigned char *p = 0x64027198 - 0x64017268 = 0xff30
+```
+
+and at memory location 0xff30 in the elf file there is the .ARM.extab section, so this code is retrieving a pointer from the exception unwinding tables.
+So, summing up, the unwind tables are coded assuming that it's possible to construct addresses to the typeinfo structures (which are in .data.rel.ro, thus in RAM) through PC-relative addressing which is not possible.
+
+From the same file we also find another useful function:
+
+```
+static _Unwind_Ptr
+base_of_encoded_value (unsigned char encoding, struct _Unwind_Context *context)
+{
+ if (encoding == DW_EH_PE_omit)
+ return 0;
+
+ switch (encoding & 0x70)
+ {
+ case DW_EH_PE_absptr:
+ case DW_EH_PE_pcrel:
+ case DW_EH_PE_aligned:
+ return 0;
+
+ case DW_EH_PE_textrel:
+ return _Unwind_GetTextRelBase (context);
+ case DW_EH_PE_datarel:
+ return _Unwind_GetDataRelBase (context);
+ case DW_EH_PE_funcrel:
+ return _Unwind_GetRegionStart (context);
+ }
+ __gxx_abort ();
+}
+```
+
+This function computes the `base` parameter the the previous function, and returns zero since encoding is 0x10 or `DW_EH_PE_pcrel`.
+
+However, `_Unwind_GetDataRelBase()` is in `libgcc/config/arm/pr-support.c`
+
+```
+/* These two should never be used. */
+
+_Unwind_Ptr
+_Unwind_GetDataRelBase (_Unwind_Context *context __attribute__ ((unused)))
+{
+ abort ();
+}
+```
+
+great, so that's unimplemented...
+
+One last bit we need to get the whole picture: how the compiler selects which encoding to use: `cd gcc/config/arm && grep -R 'DW_EH_PE_'`
+
+which found the list of constants:
+
+```
+#define DW_EH_PE_absptr 0x00
+
+#define DW_EH_PE_pcrel 0x10
+#define DW_EH_PE_textrel 0x20
+#define DW_EH_PE_datarel 0x30
+#define DW_EH_PE_funcrel 0x40
+#define DW_EH_PE_aligned 0x50
+
+#define DW_EH_PE_indirect 0x80
+```
+
+and this file `gcc/config/arm/arm.h` which says
+
+```
+#ifndef ARM_TARGET2_DWARF_FORMAT
+#define ARM_TARGET2_DWARF_FORMAT DW_EH_PE_pcrel
+#endif
+
+/* ttype entries (the only interesting data references used)
+ use TARGET2 relocations. */
+#define ASM_PREFERRED_EH_DATA_FORMAT(code, data) \
+ (((code) == 0 && (data) == 1 && ARM_UNWIND_INFO) ? ARM_TARGET2_DWARF_FORMAT \
+ : DW_EH_PE_absptr)
+```
+
+And this is actually documented!
+
+`https://gcc.gnu.org/onlinedocs/gccint/Exception-Handling.html`
+
+`ASM_PREFERRED_EH_DATA_FORMAT (code, global)`
+
+So, despite the macro implementation in `arm.h` calls the parameters `code` and `data`, they are actually `code` and `global`:
+
+`code`:
+
+* 0 for data
+* 1 for code labels
+* 2 for function pointers
+
+while `global` is true if the symbol may be affected by dynamic relocations.
+
+From my understanding, the encoding is absptr unless we're accessing data and dynamic relocations may occur (ARM_UNWIND_INFO is the constant 1 so it's always true), in that case it's pcrel.
+
+A possible solution that was tested is:
+
+* `#define ARM_TARGET2_DWARF_FORMAT DW_EH_PE_datarel`
+* implement `_Unwind_GetDataRelBase`.
+
+This is the patch that does the first thing:

+
+Yes, despite we're wasting bytes in the binary to encode the format of pointer entries, they serve nothing as they are overridden by a compile-time kludge that forces the runtime library to ignore it...
+
+`https://gcc.gnu.org/legacy-ml/gcc-patches/2011-09/msg00765.html`

+

+
+At runtime, in the process, `read_encoded_value_with_base` is called with the following parameters:
+```
+unsigned char encoding = 0x30
+_Unwind_Ptr base = 0x64100000
+const unsigned char *p = 0x640271c4
+```
+
+The first two parameters are correct, the third one, is not.
+
+This time the encoding is the correct value. Also the base is ok, so we have the data base address. However, p points to where the offset is stored in the unwinding tables. And dereferencing that location we find 0x0fff023c. This is wrong, as the target we want is at 0x10000188, and 0x64100000 + 0x0fff023c = 0x740f023c which is the faulting address causing the segfault and not the target address.
+
+So while everything is set up for data-relative, the offset that gets encoded is still pc-relative...
+
+And it is here when things get complicated, as we need to llok deep into what's encoded in the unwinding tables.
+
+When compiling the simple `main.cpp` that throws at the beginning of this chapter, GCC produces the following tables, and the unwind tables end up in the binary, with a one-to-one match, (after the ULEB128 encoding is understood `https://en.wikipedia.org/wiki/LEB128`):

+ .word _ZTIi(TARGET2) 3c02ff0f (0x0fff023c)
+```
+
+So the problematic offset is right at the end, 0x0fff023c. However, GCC is not producing the address, it just outputs `.word _ZTIi(TARGET2)`. In this declaration, `_ZTIi` is the target symbol we want to access, and `(TARGET2)` a relocation type.
+
+Who prints this `.word _ZTIi(TARGET2)` in GCC? We're back to our friend, the `output_one_function_exception_table` in `gcc/except.c`. Just like the address is last in the exception tables, also the code that prints is last in the function,
+
+```
+ if (targetm.arm_eabi_unwinder)
+ {
+ tree type;
+ for (i = 0;
+ vec_safe_iterate (cfun->eh->ehspec_data.arm_eabi, i, &type); ++i)
+ output_ttype (type, tt_format, tt_format_size);
+ }
+```
+
+The job is done by the `output_ttype`, but not exactly, as this function contains a
+
+```
+ /* Allow the target to override the type table entry format. */
+ if (targetm.asm_out.ttype (value))
+ return;
+```
+
+and the ARM target has this function pointer non-null, and thus overrides the default `output_ttype` behavior. Following the code we get back to `arm.c`.
+
+```
+static bool
+arm_output_ttype (rtx x)
+{
+ fputs ("\t.word\t", asm_out_file);
+ output_addr_const (asm_out_file, x);
+ /* Use special relocations for symbol references. */
+ if (!CONST_INT_P (x))
+ fputs ("(TARGET2)", asm_out_file);
+ fputc ('\n', asm_out_file);
+
+ return TRUE;
+}
+```
+
+and this is the function that prints the symbol name and `(TARGET2)`.
+
+adding an `if(flag_pic) return FALSE;` at the beginning of this function just affords an internal compiler error, apparently as by returning false we get back to `output_ttype` which calls `dw2_asm_output_encoded_addr_rtx` that contains a
+
+```
+#ifdef ASM_OUTPUT_DWARF_DATAREL
+ case DW_EH_PE_datarel:
+ gcc_assert (GET_CODE (addr) == SYMBOL_REF);
+ ASM_OUTPUT_DWARF_DATAREL (asm_out_file, size, XSTR (addr, 0));
+ break;
+#endif
+```
+
+and none is provided (sigh).
+
+Ok, backtracking, batching and trying to patch `arm_output_ttype` to produce another relocation type. But which type? The "ELF for the ARM Architecture" document availbale online seems to hint that ` R_ARM_BASE_ABS` is the right one, as it's a static relocation where the target is accessed as B(S) + A, which seems right.
+
+
+```

+
+ return TRUE;
+```
+
+And here we find more trouble: the gnu assember does not support the relocation we want being input from assembly files...
+
+Ok, backtracking again, we'll have to make TARGET2 relocations work for our platform. GNU ld has an option, `--target2=<type>` that allows to override how it handles target2 relocations. Great!
+By grepping the sources (couldn't find what strings are accepted as type) it looks like the options are `abs`, `rel`, `got-rel`. The default behavior we're seeing is `rel`. `got-rel` seems promising on paper, but it produces garbage for unknown reasons. `abs` is best actually, as it produces the absolute address of the symbol, like 0x10000178. Of course, by just subtracting DATA_BASE, we get the data-relative offset we want. Maybe we could patch the unwinder to subtract DATA_BASE, but it looks like there's a problem.
+
+Miosix does not load binaries compiled with `--target2=abs`, and the reason is simple, other than producing the absolute value, the linker produces a dynamic relocation to fix it up at runtime, as we're in PIE/PIC mode, and for the first time that's NOT what we want, as relocations in a readonly sections can't be made. However, by temporarily commenting out that check in the kernel, adding a check to skip this wrong relocation and patching the binary by hand by removing 0x10000000 to that address, the process works and throws correctly with the readonly unwinding tables.
+
+Now, we just need a non-kludge way to do this.
+
+For this, there's no escape to patching binutils too. The patch first adds the `--target2=mx-data-rel` option and maps it to a brand new static relocation type, `R_ARM_MIOSIXPROC_TGT2`, that is basically the same as `R_ARM_ABS32` (the one behind `--target2=abs`) except it does not leave dynamic relocations behind and subtracts DATA_BASE), making a true data-rel static relocation encoding the offset of the symbol from the data base address.
+
+And that, finally, worked.
+
+
+
+
+## Caveat fot future patchers
+
+If you do an `arm-miosix-eaby-objdump -Dslx main.bin` (of course before it's stripped and mx-postlinked), the start of the disassembly is something like
+
+```
+Program Header:
+ LOAD off 0x00000098 vaddr 0x00000098 paddr 0x00000098 align 2**3
+ filesz 0x00004fcc memsz 0x00004fcc flags r-x
+ LOAD off 0x00005068 vaddr 0x40000000 paddr 0x40000000 align 2**3
+ filesz 0x00000640 memsz 0x00000840 flags rw-
+ DYNAMIC off 0x000050f8 vaddr 0x40000090 paddr 0x40000090 align 2**2
+ filesz 0x00000048 memsz 0x00000048 flags rw-
+
+Dynamic Section:
+ DEBUG 0x00000000
+ REL 0x00004564
+ RELSZ 0x00000b00
+ RELENT 0x00000008
+ FLAGS_1 0x08000000
+ RELCOUNT 0x00000001
+private flags = 5000200: [Version5 EABI] [soft-float ABI]
+```
+
+which is more useful than it looks, as it allows to see if the binary is good looking. Sometimes innocuous-looking changes in the linker script such as renaming an output section trigger special behavior in the linker with strange side effects, such as adding useless entries to dynamic (such as if you call an output section `.init_array`), adding useless nested segments (such as calling an output section `.ARM.exidx`), or making the text segment writable, which then Miosix will of course fail to load as it violates `W^X`. So do check those when making changes!

++
++## To update this file, have a look in t-multilib and t-rmprofile and bring over

++# 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.

++
++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
++ [$ac_default_prefix]
++ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
++ [PREFIX]

++an installation prefix other than \`$ac_default_prefix' using \`--prefix',
++for instance \`--prefix=\$HOME'.
