sim: ppc: always compile in the sysv sem & shm device files

Move the stub logic to the device files themselves.  This makes the
configure & build logic more static which will make it easier to move
to the top-level build, and matches what we did with the common/ hw
tree already.

This also decouples the logic from the two -- in the past, you needed
both sem & shm in order to enable the device models, but now each one
is tied to its own independent knob.  Practically speaking, this will
probably not make a difference, but it simplifies the build a bit.

-It likes to use TCP/IP between the simulator and the host, which is

-
-I've added created a new Makefile.in (the original in Makefile.orig)
-to build a version of the simulator without the TCP/IP stuff, and a
-wrapper.c to link directly into gdb and the run command.
-
-It should be possible (barring major changes in the layout of
-the armulator) to upgrade the simulator by copying all the files
-out of a release into this directory and renaming the Makefile.
-

-/* DEVICE
-
-
-   glue - glue to interconnect and test hardware ports
-
-
-   DESCRIPTION
-
-
-   The glue device provides two functions.  Firstly, it provides a
-   mechanism for inspecting and driving the port network.  Secondly,
-   it provides a set of boolean primitives that can be used to apply
-   combinatorial operations to the port network.
-
-   Glue devices have a variable number of big endian <<output>>
-   registers.  Each register is target-word sized.  The registers can
-   be read and written.
-
-   Writing to an output register results in an event being driven
-   (level determined by the value written) on the devices
-   corresponding output port.
-
-   Reading an <<output>> register returns either the last value
-   written or the most recently computed value (for that register) as
-   a result of an event ariving on that port (which ever was computed
-   last).
-
-   At present the following sub device types are available:
-
-   <<glue>>: In addition to driving its output interrupt port with any
-   value written to an interrupt input port is stored in the
-   corresponding <<output>> register.  Such input interrupts, however,
-   are not propogated to an output interrupt port.
-
-   <<glue-and>>: The bit-wise AND of the interrupt inputs is computed
-   and then both stored in <<output>> register zero and propogated to
-   output interrupt output port zero.
-
-
-   PROPERTIES
-
-
-   reg = <address> <size> (required)
-
-   Specify the address (within the parent bus) that this device is to
-   live.  The address must be 2048 * sizeof (word) (8k in a 32bit
-   simulation) aligned.
-
-
-   interrupt-ranges = <int-number> <range> (optional)
-
-   If present, this specifies the number of valid interrupt inputs (up
-   to the maximum of 2048).  By default, <<int-number>> is zero and
-   range is determined by the <<reg>> size.
-
-
-   PORTS
-
-
-   int[0..] (input, output)
-
-   Both an input and an output port.
-
-
-   EXAMPLES
-
-
-   Enable tracing of the device:
-
-   | -t glue-device \
-
-
-   Create source, bitwize-and, and sink glue devices.  Since the
-   device at address <<0x10000>> is of size <<8>> it will have two
-   output interrupt ports.

-/* DEVICE
-
-
-   pal - glue logic device containing assorted junk
-
-
-   DESCRIPTION
-
-
-   Typical hardware dependant hack.  This device allows the firmware
-   to gain access to all the things the firmware needs (but the OS
-   doesn't).
-
-   The pal contains the following registers:
-
-   |0	reset register (write, 8bit)
-   |4	processor id register (read, 8bit)
-   |8	interrupt register (8 - port, 9 - level) (write, 16bit)
-   |12	processor count register (read, 8bit)
-
-   |16	tty input fifo register (read, 8bit)
-   |20	tty input status register (read, 8bit)
-   |24	tty output fifo register (write, 8bit)
-   |28	tty output status register (read, 8bit)
-
-   |32  countdown register (read/write, 32bit, big-endian)
-   |36  countdown value register (read, 32bit, big-endian)
-   |40  timer register (read/write, 32bit, big-endian)
-   |44  timer value register (read, 32bit, big-endian)
-
-   RESET (write): halts the simulator.  The value written to the
-   register is used as an exit status.
-
-   PROCESSOR ID (read): returns the processor identifier (0 .. N-1) of
-   the processor performing the read.
-
-   INTERRUPT (write): This register must be written using a two byte
-   store.  The low byte specifies a port and the upper byte specifies
-   the a level.  LEVEL is driven on the specified port.  By
-   convention, the pal's interrupt ports (int0, int1, ...) are wired
-   up to the corresponding processor's level sensative external
-   interrupt pin.  Eg: A two byte write to address 8 of 0x0102
-   (big-endian) will result in processor 2's external interrupt pin
-   being asserted.
-
-   PROCESSOR COUNT (read): returns the total number of processors
-   active in the current simulation.
-
-   TTY INPUT FIFO (read): if the TTY input status register indicates a
-   character is available by being nonzero, returns the next available
-   character from the pal's tty input port.
-
-   TTY OUTPUT FIFO (write): if the TTY output status register
-   indicates the output fifo is not full by being nonzero, outputs the
-   character written to the tty's output port.
-
-   COUNDOWN (read/write): The countdown registers provide a
-   non-repeating timed interrupt source.  Writing a 32 bit big-endian
-   zero value to this register clears the countdown timer.  Writing a
-   non-zero 32 bit big-endian value to this register sets the
-   countdown timer to expire in VALUE ticks (ticks is target
-   dependant).  Reading the countdown register returns the last value
-   writen.
-
-   COUNTDOWN VALUE (read): Reading this 32 bit big-endian register
-   returns the number of ticks remaining until the countdown timer
-   expires.
-
-   TIMER (read/write): The timer registers provide a periodic timed
-   interrupt source.  Writing a 32 bit big-endian zero value to this
-   register clears the periodic timer.  Writing a 32 bit non-zero
-   value to this register sets the periodic timer to triger every
-   VALUE ticks (ticks is target dependant).  Reading the timer
-   register returns the last value written.
-
-   TIMER VALUE (read): Reading this 32 bit big-endian register returns
-   the number of ticks until the next periodic interrupt.
-
-
-   PROPERTIES
-
-
-   reg = <address> <size> (required)
-
-   Specify the address (within the parent bus) that this device is to
-   be located.
-
-   poll? = <boolean>
-
-   If present and true, indicates that the device should poll its
-   input.
-
-
-   PORTS
-
-
-   int[0..NR_PROCESSORS] (output)
-
-   Driven as a result of a write to the interrupt-port /
-   interrupt-level register pair.
-
-
-   countdown
-
-   Driven whenever the countdown counter reaches zero.
-
-
-   timer
-
-   Driven whenever the timer counter reaches zero.
-
-
-   BUGS
-
-
-   At present the common simulator framework does not support input
-   polling.

+PREAMBLE
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document @dfn{free} in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+
+This License is a kind of ``copyleft'', which means that derivative
+works of the document must themselves be free in the same sense.  It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does.  But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book.  We recommend this License
+principally for works whose purpose is instruction or reference.
+
+@item
+APPLICABILITY AND DEFINITIONS
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License.  Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein.  The ``Document'', below,
+refers to any such manual or work.  Any member of the public is a
+licensee, and is addressed as ``you''.  You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+
+A ``Modified Version'' of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A ``Secondary Section'' is a named appendix or a front-matter section
+of the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall
+subject (or to related matters) and contains nothing that could fall
+directly within that overall subject.  (Thus, if the Document is in
+part a textbook of mathematics, a Secondary Section may not explain
+any mathematics.)  The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The ``Invariant Sections'' are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License.  If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant.  The Document may contain zero
+Invariant Sections.  If the Document does not identify any Invariant
+Sections then there are none.
+
+The ``Cover Texts'' are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License.  A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+A ``Transparent'' copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters.  A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text.  A copy that is not ``Transparent'' is called ``Opaque''.
+
+Examples of suitable formats for Transparent copies include plain
+@sc{ascii} without markup, Texinfo input format, La@TeX{} input
+format, @acronym{SGML} or @acronym{XML} using a publicly available
+@acronym{DTD}, and standard-conforming simple @acronym{HTML},
+PostScript or @acronym{PDF} designed for human modification.  Examples
+of transparent image formats include @acronym{PNG}, @acronym{XCF} and
+@acronym{JPG}.  Opaque formats include proprietary formats that can be
+read and edited only by proprietary word processors, @acronym{SGML} or
+@acronym{XML} for which the @acronym{DTD} and/or processing tools are
+not generally available, and the machine-generated @acronym{HTML},
+PostScript or @acronym{PDF} produced by some word processors for
+output purposes only.
+
+The ``Title Page'' means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page.  For works in
+formats which do not have any title page as such, ``Title Page'' means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+The ``publisher'' means any person or entity that distributes copies
+of the Document to the public.
+
+A section ``Entitled XYZ'' means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language.  (Here XYZ stands for a
+specific section name mentioned below, such as ``Acknowledgements'',
+``Dedications'', ``Endorsements'', or ``History''.)  To ``Preserve the Title''
+of such a section when you modify the Document means that it remains a
+section ``Entitled XYZ'' according to this definition.
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document.  These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+
+@item
+VERBATIM COPYING
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License.  You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute.  However, you may accept
+compensation in exchange for copies.  If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+@item
+COPYING IN QUANTITY
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover.  Both covers must also clearly and legibly identify
+you as the publisher of these copies.  The front cover must present
+the full title with all words of the title equally prominent and
+visible.  You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+
+@item
+MODIFICATIONS
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it.  In addition, you must do these things in the Modified Version:
+
+@enumerate A
+@item
+Use in the Title Page (and on the covers, if any) a title distinct
+from that of the Document, and from those of previous versions
+(which should, if there were any, be listed in the History section
+of the Document).  You may use the same title as a previous version
+if the original publisher of that version gives permission.
+
+@item
+List on the Title Page, as authors, one or more persons or entities
+responsible for authorship of the modifications in the Modified
+Version, together with at least five of the principal authors of the
+Document (all of its principal authors, if it has fewer than five),
+unless they release you from this requirement.
+
+@item
+State on the Title page the name of the publisher of the
+Modified Version, as the publisher.
+
+@item
+Preserve all the copyright notices of the Document.
+
+@item
+Add an appropriate copyright notice for your modifications
+adjacent to the other copyright notices.
+
+@item
+Include, immediately after the copyright notices, a license notice
+giving the public permission to use the Modified Version under the
+terms of this License, in the form shown in the Addendum below.
+
+@item
+Preserve in that license notice the full lists of Invariant Sections
+and required Cover Texts given in the Document's license notice.
+
+@item
+Include an unaltered copy of this License.
+
+@item
+Preserve the section Entitled ``History'', Preserve its Title, and add
+to it an item stating at least the title, year, new authors, and
+publisher of the Modified Version as given on the Title Page.  If
+there is no section Entitled ``History'' in the Document, create one
+stating the title, year, authors, and publisher of the Document as
+given on its Title Page, then add an item describing the Modified
+Version as stated in the previous sentence.
+
+@item
+Preserve the network location, if any, given in the Document for
+public access to a Transparent copy of the Document, and likewise
+the network locations given in the Document for previous versions
+it was based on.  These may be placed in the ``History'' section.
+You may omit a network location for a work that was published at
+least four years before the Document itself, or if the original
+publisher of the version it refers to gives permission.
+
+@item
+For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve
+the Title of the section, and preserve in the section all the
+substance and tone of each of the contributor acknowledgements and/or
+dedications given therein.
+
+@item
+Preserve all the Invariant Sections of the Document,
+unaltered in their text and in their titles.  Section numbers
+or the equivalent are not considered part of the section titles.
+
+@item
+Delete any section Entitled ``Endorsements''.  Such a section
+may not be included in the Modified Version.
+
+@item
+Do not retitle any existing section to be Entitled ``Endorsements'' or
+to conflict in title with any Invariant Section.
+
+@item
+Preserve any Warranty Disclaimers.
+@end enumerate
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant.  To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section Entitled ``Endorsements'', provided it contains
+nothing but endorsements of your Modified Version by various
+parties---for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version.  Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity.  If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+@item
+COMBINING DOCUMENTS
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy.  If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections Entitled ``History''
+in the various original documents, forming one section Entitled
+``History''; likewise combine any sections Entitled ``Acknowledgements'',
+and any sections Entitled ``Dedications''.  You must delete all
+sections Entitled ``Endorsements.''
+
+@item
+COLLECTIONS OF DOCUMENTS
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+@item
+AGGREGATION WITH INDEPENDENT WORKS
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an ``aggregate'' if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+
+@item
+TRANSLATION
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections.  You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers.  In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+If a section in the Document is Entitled ``Acknowledgements'',
+``Dedications'', or ``History'', the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+
+@item
+TERMINATION
+
+You may not copy, modify, sublicense, or distribute the Document
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense, or distribute it is void, and
+will automatically terminate your rights under this License.
+
+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, receipt of a copy of some or all of the same material does
+not give you any rights to use it.
+
+@item
+FUTURE REVISIONS OF THIS LICENSE
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation 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.  See
+@uref{http://www.gnu.org/copyleft/}.
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License ``or any later version'' applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation.  If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation.  If the Document
+specifies that a proxy can decide which future versions of this
+License can be used, that proxy's public statement of acceptance of a
+version permanently authorizes you to choose that version for the
+Document.
+
+@item
+RELICENSING
+
+``Massive Multiauthor Collaboration Site'' (or ``MMC Site'') means any
+World Wide Web server that publishes copyrightable works and also
+provides prominent facilities for anybody to edit those works.  A
+public wiki that anybody can edit is an example of such a server.  A
+``Massive Multiauthor Collaboration'' (or ``MMC'') contained in the
+site means any set of copyrightable works thus published on the MMC
+site.
+
+``CC-BY-SA'' means the Creative Commons Attribution-Share Alike 3.0
+license published by Creative Commons Corporation, a not-for-profit
+corporation with a principal place of business in San Francisco,
+California, as well as future copyleft versions of that license
+published by that same organization.
+
+``Incorporate'' means to publish or republish a Document, in whole or
+in part, as part of another Document.
+
+An MMC is ``eligible for relicensing'' if it is licensed under this
+License, and if all works that were first published under this License
+somewhere other than this MMC, and subsequently incorporated in whole
+or in part into the MMC, (1) had no cover texts or invariant sections,
+and (2) were thus incorporated prior to November 1, 2008.
+
+The operator of an MMC Site may republish an MMC contained in the site
+under CC-BY-SA on the same site at any time before August 1, 2009,
+provided the MMC is eligible for relicensing.

+@heading ADDENDUM: How to use this License for your documents
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and
+license notices just after the title page:
+
+@smallexample
+@group
+  Copyright (C)  @var{year}  @var{your name}.
+  Permission is granted to copy, distribute and/or modify this document
+  under the terms of the GNU Free Documentation License, Version 1.3
+  or any later version published by the Free Software Foundation;
+  with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+  Texts.  A copy of the license is included in the section entitled ``GNU
+  Free Documentation License''.
+@end group
+@end smallexample
+
+If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
+replace the ``with@dots{}Texts.'' line with this:
+
+@smallexample
+@group
+    with the Invariant Sections being @var{list their titles}, with
+    the Front-Cover Texts being @var{list}, and with the Back-Cover Texts
+    being @var{list}.
+@end group
+@end smallexample
+
+If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License,
+to permit their use in free software.

-= OVERVIEW =
-
-The Synacor Challenge is a fun programming exercise with a number of puzzles
-built into it.  You can find more details about it here:
-https://challenge.synacor.com/
-
-The first puzzle is writing an interpreter for their custom ISA.  This is a
-simulator for that custom CPU.  The CPU is quite basic: it's 16-bit with only
-8 registers and a limited set of instructions.  This means the port will never
-grow new features.  See README.arch-spec for more details.
-
-Implementing it here ends up being quite useful: it acts as a simple constrained
-"real world" example for people who want to implement a new simulator for their
-own architecture.  We demonstrate all the basic fundamentals (registers, memory,
-branches, and tracing) that all ports should have.

-== architecture ==
-- three storage regions
-  - memory with 15-bit address space storing 16-bit values
-  - eight registers
-  - an unbounded stack which holds individual 16-bit values
-- all numbers are unsigned integers 0..32767 (15-bit)
-- all math is modulo 32768; 32758 + 15 => 5
-
-== binary format ==
-- each number is stored as a 16-bit little-endian pair (low byte, high byte)
-- numbers 0..32767 mean a literal value
-- numbers 32768..32775 instead mean registers 0..7
-- numbers 32776..65535 are invalid
-- programs are loaded into memory starting at address 0
-- address 0 is the first 16-bit value, address 1 is the second 16-bit value, etc
-
-== execution ==
-- After an operation is executed, the next instruction to read is immediately after the last argument of the current operation.
-  If a jump was performed, the next operation is instead the exact destination of the jump.
-- Encountering a register as an operation argument should be taken as reading from the register or setting into the register as appropriate.
-
-== hints ==
-- Start with operations 0, 19, and 21.
-- Here's a code for the challenge website: jTTockJlJiOC
-- The program "9,32768,32769,4,19,32768" occupies six memory addresses and should:
-  - Store into register 0 the sum of 4 and the value contained in register 1.
-  - Output to the terminal the character with the ascii code contained in register 0.
-
-== opcode listing ==
-halt: 0
-  stop execution and terminate the program
-set: 1 a b
-  set register <a> to the value of <b>
-push: 2 a
-  push <a> onto the stack
-pop: 3 a
-  remove the top element from the stack and write it into <a>; empty stack = error
-eq: 4 a b c
-  set <a> to 1 if <b> is equal to <c>; set it to 0 otherwise
-gt: 5 a b c
-  set <a> to 1 if <b> is greater than <c>; set it to 0 otherwise
-jmp: 6 a
-  jump to <a>
-jt: 7 a b
-  if <a> is nonzero, jump to <b>
-jf: 8 a b
-  if <a> is zero, jump to <b>
-add: 9 a b c
-  assign into <a> the sum of <b> and <c> (modulo 32768)
-mult: 10 a b c
-  store into <a> the product of <b> and <c> (modulo 32768)
-mod: 11 a b c
-  store into <a> the remainder of <b> divided by <c>
-and: 12 a b c
-  stores into <a> the bitwise and of <b> and <c>
-or: 13 a b c
-  stores into <a> the bitwise or of <b> and <c>
-not: 14 a b
-  stores 15-bit bitwise inverse of <b> in <a>
-rmem: 15 a b
-  read memory at address <b> and write it to <a>
-wmem: 16 a b
-  write the value from <b> into memory at address <a>
-call: 17 a
-  write the address of the next instruction to the stack and jump to <a>
-ret: 18
-  remove the top element from the stack and jump to it; empty stack = halt
-out: 19 a
-  write the character represented by ascii code <a> to the terminal
-in: 20 a
-  read a character from the terminal and write its ascii code to <a>; it can be assumed that once input starts, it will continue until a newline is encountered; this means that you can safely read whole lines from the keyboard and trust that they will be fully read
-noop: 21
-  no operation
