gnuwin32: Remove old versions of bison/flex from the distribution
The win_flex/win_bison tools are already in the repository and working with all projects, so the GnuWin32 versions can be removed and the winflexbison versions can take their place.

-* Bison-2.4.1 for Windows *
-===========================
-
-What is it?
------------
-Bison: Yacc-compatible parser generator
-
-Description
------------
-Bison is a general purpose parser generator that converts a grammar description for an LALR(1) context-free grammar into a C program to parse that grammar. Bison can be used to develop a wide range of language parsers, from ones used in simple desk calculators to complex programming languages. Bison is upwardly compatible with Yacc, so any correctly written Yacc grammar should work with Bison without any changes. If you know Yacc, you shouldn't have any trouble using Bison. You do need to be very proficient in C programming to be able to use Bison. Bison is only needed on systems that are used for development. If your system will be used for C development, you should install Bison. The package contains also the -ly library sometimes used by programs using Bison-generated parsers. If you are developing programs using Bison, you might want to link with this library. This library is not required by all Bison-generated parsers, but may be employed by simple programs to supply minimal support for the generated parsers.

-1 Notes on the Free Translation Project
-***************************************
-
-Free software is going international! The Free Translation Project is
-a way to get maintainers of free software, translators, and users all
-together, so that free software will gradually become able to speak many
-languages. A few packages already provide translations for their
-messages.
-
- If you found this `ABOUT-NLS' file inside a distribution, you may
-assume that the distributed package does use GNU `gettext' internally,
-itself available at your nearest GNU archive site. But you do _not_
-need to install GNU `gettext' prior to configuring, installing or using
-this package with messages translated.
-
- Installers will find here some useful hints. These notes also
-explain how users should proceed for getting the programs to use the
-available translations. They tell how people wanting to contribute and
-work on translations can contact the appropriate team.
-
- When reporting bugs in the `intl/' directory or bugs which may be
-related to internationalization, you should tell about the version of
-`gettext' which is used. The information can be found in the
-`intl/VERSION' file, in internationalized packages.
-
-1.1 Quick configuration advice
-==============================
-
-If you want to exploit the full power of internationalization, you
-should configure it using
-
- ./configure --with-included-gettext
-
-to force usage of internationalizing routines provided within this
-package, despite the existence of internationalizing capabilities in the
-operating system where this package is being installed. So far, only
-the `gettext' implementation in the GNU C library version 2 provides as
-many features (such as locale alias, message inheritance, automatic
-charset conversion or plural form handling) as the implementation here.
-It is also not possible to offer this additional functionality on top
-of a `catgets' implementation. Future versions of GNU `gettext' will
-very likely convey even more functionality. So it might be a good idea
-to change to GNU `gettext' as soon as possible.
-
- So you need _not_ provide this option if you are using GNU libc 2 or
-you have installed a recent copy of the GNU gettext package with the
-included `libintl'.
-
-1.2 INSTALL Matters
-===================
-
-Some packages are "localizable" when properly installed; the programs
-they contain can be made to speak your own native language. Most such
-packages use GNU `gettext'. Other packages have their own ways to
-internationalization, predating GNU `gettext'.
-
- By default, this package will be installed to allow translation of
-messages. It will automatically detect whether the system already
-provides the GNU `gettext' functions. If not, the included GNU
-`gettext' library will be used. This library is wholly contained
-within this package, usually in the `intl/' subdirectory, so prior
-installation of the GNU `gettext' package is _not_ required.
-Installers may use special options at configuration time for changing
-the default behaviour. The commands:
-
- ./configure --with-included-gettext
- ./configure --disable-nls
-
-will, respectively, bypass any pre-existing `gettext' to use the
-internationalizing routines provided within this package, or else,
-_totally_ disable translation of messages.
-
- When you already have GNU `gettext' installed on your system and run
-configure without an option for your new package, `configure' will
-probably detect the previously built and installed `libintl.a' file and
-will decide to use this. This might not be desirable. You should use
-the more recent version of the GNU `gettext' library. I.e. if the file
-`intl/VERSION' shows that the library which comes with this package is
-more recent, you should use
-
- ./configure --with-included-gettext
-
-to prevent auto-detection.
-
- The configuration process will not test for the `catgets' function
-and therefore it will not be used. The reason is that even an
-emulation of `gettext' on top of `catgets' could not provide all the
-extensions of the GNU `gettext' library.
-
- Internationalized packages usually have many `po/LL.po' files, where
-LL gives an ISO 639 two-letter code identifying the language. Unless
-translations have been forbidden at `configure' time by using the
-`--disable-nls' switch, all available translations are installed
-together with the package. However, the environment variable `LINGUAS'
-may be set, prior to configuration, to limit the installed set.
-`LINGUAS' should then contain a space separated list of two-letter
-codes, stating which languages are allowed.
-
-1.3 Using This Package
-======================
-
-As a user, if your language has been installed for this package, you
-only have to set the `LANG' environment variable to the appropriate
-`LL_CC' combination. Here `LL' is an ISO 639 two-letter language code,
-and `CC' is an ISO 3166 two-letter country code. For example, let's
-suppose that you speak German and live in Germany. At the shell
-prompt, merely execute `setenv LANG de_DE' (in `csh'),
-`export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash').
-This can be done from your `.login' or `.profile' file, once and for
-all.
-
- You might think that the country code specification is redundant.
-But in fact, some languages have dialects in different countries. For
-example, `de_AT' is used for Austria, and `pt_BR' for Brazil. The
-country code serves to distinguish the dialects.
-
- The locale naming convention of `LL_CC', with `LL' denoting the
-language and `CC' denoting the country, is the one use on systems based
-on GNU libc. On other systems, some variations of this scheme are
-used, such as `LL' or `LL_CC.ENCODING'. You can get the list of
-locales supported by your system for your language by running the
-command `locale -a | grep '^LL''.
-
- Not all programs have translations for all languages. By default, an
-English message is shown in place of a nonexistent translation. If you
-understand other languages, you can set up a priority list of languages.
-This is done through a different environment variable, called
-`LANGUAGE'. GNU `gettext' gives preference to `LANGUAGE' over `LANG'
-for the purpose of message handling, but you still need to have `LANG'
-set to the primary language; this is required by other parts of the
-system libraries. For example, some Swedish users who would rather
-read translations in German than English for when Swedish is not
-available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'.
-
- Special advice for Norwegian users: The language code for Norwegian
-bokma*l changed from `no' to `nb' recently (in 2003). During the
-transition period, while some message catalogs for this language are
-installed under `nb' and some older ones under `no', it's recommended
-for Norwegian users to set `LANGUAGE' to `nb:no' so that both newer and
-older translations are used.
-
- In the `LANGUAGE' environment variable, but not in the `LANG'
-environment variable, `LL_CC' combinations can be abbreviated as `LL'
-to denote the language's main dialect. For example, `de' is equivalent
-to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT'
-(Portuguese as spoken in Portugal) in this context.
-
-1.4 Translating Teams
-=====================
-
-For the Free Translation Project to be a success, we need interested
-people who like their own language and write it well, and who are also
-able to synergize with other translators speaking the same language.
-Each translation team has its own mailing list. The up-to-date list of
-teams can be found at the Free Translation Project's homepage,
-`http://www.iro.umontreal.ca/contrib/po/HTML/', in the "National teams"
-area.
-
- If you'd like to volunteer to _work_ at translating messages, you
-should become a member of the translating team for your own language.
-The subscribing address is _not_ the same as the list itself, it has
-`-request' appended. For example, speakers of Swedish can send a
-message to `sv-request@li.org', having this message body:
-
- subscribe
-
- Keep in mind that team members are expected to participate
-_actively_ in translations, or at solving translational difficulties,
-rather than merely lurking around. If your team does not exist yet and
-you want to start one, or if you are unsure about what to do or how to
-get started, please write to `translation@iro.umontreal.ca' to reach the
-coordinator for all translator teams.
-
- The English team is special. It works at improving and uniformizing
-the terminology in use. Proven linguistic skill are praised more than
-programming skill, here.
-
-1.5 Available Packages
-======================
-
-Languages are not equally supported in all packages. The following
-matrix shows the current state of internationalization, as of July
-2006. The matrix shows, in regard of each package, for which languages
-PO files have been submitted to translation coordination, with a
-translation percentage of at least 50%.

- For a PO file in the matrix above to be effective, the package to

-1.6 Using `gettext' in new packages
-===================================
-
-If you are writing a freely available program and want to
-internationalize it you are welcome to use GNU `gettext' in your
-package. Of course you have to respect the GNU Library General Public
-License which covers the use of the GNU `gettext' library. This means
-in particular that even non-free programs can use `libintl' as a shared
-library, whereas only free software can use `libintl' as a static
-library or use modified versions of `libintl'.
-
- Once the sources are changed appropriately and the setup can handle
-the use of `gettext' the only thing missing are the translations. The
-Free Translation Project is also available for packages which are not
-developed inside the GNU project. Therefore the information given above
-applies also for every other Free Software Project. Contact
-`translation@iro.umontreal.ca' to make the `.pot' files available to
-the translation teams.

- 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>.

- * src/output.c (prepare_symbols): When writing yytname muscles, where
- symbol names will be encoded in C-string literals, tell quotearg to
- escape trigraphs. This used to be the default in gnulib.
- * tests/regression.at (Token definitions): Because of the change in
- gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
- escapes trigraphs in symbol names. Thus, yytname no longer has
- trigraphs unnecessarily doubly escaped. Update test case output.
- Extend test case to be sure Bison's own error messages will no longer
- have trigraphs in symbol names unnecessarily escaped once.

- * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
- starting with `yy'.
-
-2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>

- defined. Reported by Christian Burger at
- <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
- * THANKS: Add Christian Burger.

-
-2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
- determine whether this function has already complained about an invalid
- value for a %define boolean variable, don't check whether Bison has
- ever examined the value. As written, the check was a tautology.
- Instead, record and check for this complaint using a separate muscle.
-

-
- Fix push parsing memory leak reported by Brandon Lucia at
- <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.

- * tests/testsuite.at: Include push.at.
- * test/push.at: New.
- (Push Parsing: Memory Leak for Early Deletion): New test case.

-2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Improve handling of multiple S/R conflicts in the same state and of S/R
- conflicts involving multiple reductions.
- * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
- set for a state here or Bison will abort if it is reassigned on a
- later conflicted reduction in the same state.
- Similarly, don't finalize and assign the solved conflicts report here
- or it will be lost if it is reassigned on a later conflicted reduction
- in the same state.
- (set_conflicts): Instead, assign them both here after all S/R conflicts
- in the state have been fully examined.
- * src/print.c (shift_set): Rename to...
- (no_reduce_set): ... this.
- (print_reductions): Update for rename, and add %nonassoc error action
- tokens to no_reduce_set so that, when printing the first remaining
- reduction on an error action token, the reduction is enclosed in
- brackets.
- (print_results): Update for rename.
- * tests/conflicts.at (Solved conflicts report for multiple reductions
- in a state): New test case.
- (%nonassoc error actions for multiple reductions in a state): New test
- case.
-
- * src/main.c (main): Don't depend on C99 features.
-
-2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * build-aux/.cvsignore: Add compile.
- * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
- uniwidth.
-
-2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * bootstrap (slurp): Create target directories that don't exist.
- Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
-
-2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * LR0.c (new_itemsets): Fix wording in comments: say item index rather
- than item number.
- * closure.c (closure): Likewise.
- * state.h (reductions): Comment sorting of rules.
- (state): Comment sorting of items.
-
-2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Fix C++ test cases after recent Gnulib changes. Discussed starting at
- <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
- * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
- definition in order to avoid Gnulib headers since we don't use config.h
- here.
- * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
- rather than AT_DATA so that config.h is included.
-
-2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
- instead of fprintf. Guard these functions with #if YYDEBUG instead of
- #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
- and so that YYFPRINTF is guaranteed to be defined here.
-
-2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
- with...
- (muscle_percent_define_check_values): ... this more helpful function.
- Again, it's not used yet, but it will be.
- * src/muscle_tab.h: Likewise.
-
- Improve some comments in parser table construction.
- * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
- (generate_states): Don't mention ruleset, which is internal to closure.
- * src/closure.c (closure): Explain sorting of core and itemset, which
- is required for this function to behave correctly.
- * src/closure.h (closure): Mention sorting.
-
-2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * src/lalr.c (state_lookahead_tokens_count): For code readability,
- move the check for disabled transitions to an aver since conflict
- resolution hasn't happened yet.
-
- * src/lalr.c (state_lookahead_tokens_count): Remove the check that
- labels a state as inconsistent just because it has error transitions.
- The original form of this check appeared in revision 1.1 of lalr.c,
- which was committed on 1991-12-21. Now (at least), changing the
- consistency label on such a state appears to have no useful effect in
- any of the places it is examined, which I enumerate below. The key
- point to understanding each item in this enumeration is that a state
- with an error transition is labelled consistent in the first place only
- if it has no rules, so the check cannot matter for states that have
- rules. (1) Labelling a state as inconsistent will cause set_conflicts
- to try to identify its conflicts, and a state must have *rules* to have
- conflicts. (2) Labelling a state as inconsistent will affect how
- action_row sets the default *rule* for the state. (3) Labelling a
- state as inconsistent will cause build_relations to add lookback edges
- to *rules* in that state.
- * src/state.h (struct state): Word the comment for member consistent
- more carefully.
-
-2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
-

- * src/reader.c (check_and_convert_grammar): Fix for-loop.

- Don't widen struct state with member reachable just to temporarily

- * src/state.h (struct state): Remove member.
- * src/state.c (state_new): Don't initialize it.
- (state_mark_reachable_states): Rename to...
- (state_record_reachable_states): ... this, and use bitset.

-
-2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * src/Makefile.am (yacc): Quote target action commands properly so

-
- * data/glr.c (yylval): As in yacc.c, don't extern in the header for

- Undo my 2007-02-07 change, switching back to the c-strcase module
- introduced in the 2007-02-03 change. Bruno Haible reported that
- the 2007-02-07 change would be dangerous in Turkish if we add a
- language whose name contains "i", since "i" is not lowercase "I"
- in Turkish.
- * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
- * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,

- (yypstate_new): Return NULL if malloc does.
- * src/reader.c (packgram): Move translation of rule actions from the
- beginning of packgram to...
- (check_and_convert_grammar): ... here right before packgram is invoked
- so it's easier to write more complete comments, and remove redundant
- code.

- * src/getargs.c: Revert 2007-02-03 change, as follows.
- Don't include c-strcase.h.
- (language_argmatch): Use strcasecmp rather than c_strcasecmp.
- strcasecmp has "unspecified behavior" outside the POSIX locale,
- but it works fine in practice if at least one argument is ASCII,
- as is the case in Bison.

-2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * ChangeLog: For changes in doc/bison.texinfo, consistently reference
- node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
- Summary" not "Directives".
- * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
- %code entry in "Decl Summary" rather than the one in "Table of Symbols"
- since the former is now the more complete one.
- (Prologue Alternatives): Likewise and do the same for %defines.
- (Table of Symbols): Add summary of %code, add summary of %define, and
- move full %code documentation to...
- (Decl Summary): ... here for consistency with other entries in these
- sections.
- Move %define entry in order to keep this list alphabetized.
- Reword %define entry a little to put less emphasis on the skeleton

-
- Clean up %define and %code implementation in M4 some. Most
- importantly, rename all related macros to be in the b4_percent_define
- and b4_percent_code namespaces. Also, complete support for `.' in
- %define variable names and %code qualifiers.
- * data/bison.m4 (b4_check_user_names): Check for special
- "SKELETON-NAMESPACE(name)" macros instead of using two nested
- m4_foreach loops.
- (b4_get_percent_define, b4_get_percent_code): Rename to...
- (b4_percent_define_get, b4_percent_code_get): ... these.
- Extend documentation with examples.
- For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
- b4_percent_define_skeleton_variables and
- b4_percent_code_skeleton_qualifiers.
- Expect any value for the %define variable `foo' to be stored in the
- macro named `b4_percent_define(foo)'; expect any %code blocks for the
- qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
- expect any unqualified %code blocks to be stored in a macro named
- `b4_percent_code_unqualified'.
- Use m4_indir so that %define variable names and %code qualifiers can
- contain `.', which is allowed by the grammar parser.
- (b4_percent_define_default): New macro to set a default value for a
- %define variable.
- (m4_wrap): Update wrapped code, and fix some underquoting.
- (b4_check_user_names_wrap): Update and define outside the m4_wrap.
- Expect grammar uses of %define variables and %code qualifiers to be
- defined in b4_percent_define_user_variables and
- b4_percent_code_user_qualifiers.
- * data/c++.m4: Use b4_percent_define_default rather than
- m4_define_default. Fix some underquoting. Skeleton usage of %define
- variable define_location_comparison now implies skeleton usage of
- %define variable filename_type.
- * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
- data/push.c, data/yacc.c: Update macro names.

-
-2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>

- maintainer-check-valgrind.
- (Duplicate representation of merged trees): Free all semantic values.
- (Duplicated user destructor for lookahead): Likewise.
-
-2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
- command-line prefix.
- * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
- ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
- miss Valgrind messages.
- (Exploding the Stack Size with Malloc): Likewise.
-
-2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
-

- and Joel E. Denny <jdenny@ces.clemson.edu>
-
- Simplify union and prologue handling, and escape union and lex/parse
- params with digraphs.
- * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
- values to the empty string since these are no longer guaranteed
- initialized by the front-end.
- * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
- braces around b4_user_stype since this is no longer done by the
- front-end.
- * src/files.c, src/files.h (pre_prologue_obstack,
- post_prologue_obstack): Remove.
- * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
- comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
- with digraphs. This fixes lex params and parse params.
- * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
- * src/output.c (prepare): Remove muscle insertion of the prologues.
- (output): Remove freeing of pre_prologue_obstack and
- post_prologue_obstack.
- * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
- than prologue_augment for prologue parsing so you don't need prologue
- obstacks.
- (grammar_declaration): For %union RHS, use `braceless' instead of
- "{...}" so that braces are already stripped and code is escaped with
- digraphs.
- * src/reader.c (prologue_augment): Remove.
- (reader): Remove initialization of pre_prologue_obstack and
- post_prologue_obstack.
- * src/reader.h (prologue_augment): Remove.

-2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Remove quotes from variables names in %define directives and from
- qualifiers in %code directives, and restrict the characters that are
- allowed in them to M4-friendly ones. For %define, continue to support
- the quoted form as a deprecated feature. Discussed starting at
- <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
- * NEWS (2.3a+): Add entry for the change to %define. Update entry for

- (C++ Location Values): Update %define uses.
- (Calc++ Parser Interface): Likewise.
- (Calc++ Parser): Likewise, and update `%code requires' uses.
- (Table of Symbols): Update %code documentation.
- * src/parse-gram.y (prologue_declaration): For %define variables, use
- `variable' instead of `STRING'.
- (grammar_declaration): For %code qualifiers, use `ID' instead of

-
- * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
- instead of muscle_insert for %define values so that M4-special
- characters are replaced with digraphs.
- * tests/input.at (%define errors): Extend to check weird values.
-
-2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Instead of having skeletons declare all valid %define variables and
- %code qualifiers, provide macros that retrieve the associated values
- and build these lists automatically. Thus Bison will now warn when a
- variable or qualifier is not used by the skeleton in the current
- invocation regardless of whether it might sometimes be used by that
- skeleton in other invocations. Also, move all %define value macros to
- the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
- form, which is replaced by %code.
- * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
- (b4_check_user_names): ... this, and change the series of valid name
- arguments to a single list argument for names used in the skeleton
- similar to the existing list argument for names used in the grammar.
- Warn instead of complaining.
- (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
- values and %code code, to format %code code properly, and to build
- lists of all %define variables and %code qualifiers used in the
- skeleton: b4_skeleton_percent_define_variables and
- b4_skeleton_percent_code_qualifiers.
- (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
- Remove, and...
- (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
- the skeleton names lists can finish building first. In place of
- b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
- expect the lists b4_user_percent_define_variables and
- b4_user_percent_code_qualifiers.
- * data/c++.m4: Where setting default values for b4_parser_class_name,
- b4_location_type, b4_filename_type, b4_namespace, and
- b4_define_location_comparison, update their names to the
- b4_percent_define_ namespace.
- * data/glr.c: Don't use b4_check_percent_define_variables and
- b4_check_percent_code_qualifiers. Use b4_get_percent_code.
- * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
- (b4_parser_class_name, b4_namespace): Define these using
- b4_get_percent_define for parser_class_name and namespace.
- * data/location.cc: Use b4_get_percent_define.
- * data/push.c: Don't use b4_check_percent_define_variables and
- b4_check_percent_code_qualifiers. Use b4_get_percent_code.
- * data/yacc.c: Likewise, and don't call m4_exit in
- b4_use_push_for_pull_if or m4_wrap code will never execute.
- * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
- Rename to...
- (muscle_grow_user_name_list): ... this for consistency with the
- terminology used in bison.m4.
- * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
- %define variable names, and rename muscle used_percent_define_variables
- to user_percent_define_variables.
- (grammar_declaration): Rename muscle used_percent_code_qualifiers to
- user_percent_code_qualifiers.
- (content): Remove.
- (content.opt): Replace content RHS with STRING RHS so %define "NAME"
- {CODE} form is no longer accepted.
- * tests/input.at (Reject bad %code qualifiers): Rename to...
- (Reject unused %code qualifiers): ... this, and update test output.
- (%define error): Update test output.
-
-2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>

- Check for unrecognized %define variables similar to checking for
- unrecognized %code qualifiers. Check for redefined %define variables.
- * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
- generalizes...
- (b4_check_percent_code_qualifiers): ... this, which now wraps it.
- (b4_check_percent_define_variables): New, also wraps it.
- * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
- variables using b4_check_percent_define_variables.
- * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
- all those exercised in the test suite and all those listed in the
- `Default values' section of c++.m4. Are there others?
- * data/push.c, data/yacc.c: Declare no valid %define variables.
- * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
- similar to muscle_find, but it works even when the muscle stores a
- const value.
- (muscle_grow_used_name_list): New function for constructing the used
- name list muscles that b4_check_for_unrecognized_names requires.
- * src/parse-gram.y (prologue_declaration): Warn if a variable is
- %define'd more than once. Define the b4_used_percent_define_variables
- muscle with muscle_grow_used_name_list.
- (grammar_declaration): Abbreviate %code code with
- muscle_grow_used_name_list.
- * tests/input.at (%define errors): New.

-2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Provide warn_at, complain_at, and fatal_at function callbacks to the
- skeletons, and use this for %code qualifier complaints.
- * data/bison.m4 (b4_error_at): New, invoked by...
- (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
- the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
- @fatal_at(...@) directives.
- (b4_check_percent_code_qualifiers): Rewrite to expect locations for
- qualifiers in b4_used_percent_code_qualifiers and to use
- b4_complain_at.
- * src/location.c, src/location.h (boundary_set_from_string): New global
- function.
- * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
- function.
- * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
- to b4_used_percent_code_qualifiers.
- * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
- function.
- (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
- (lineno): Rename to...
- (out_lineno): ... this so I don't misunderstand it again.
- (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
- here; these newlines are in the input but not the output file.
- (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
- (at_directive_perform): ... this new static function, and add handling
- of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
- directives.
- * tests/input.at (Reject bad %code qualifiers): Update test output with
- locations and extend.
-

-
- Clean up b4_check_percent_code_qualifiers a little.
- * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
- in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
- documentation and add examples.
- * src/parse-gram.y (grammar_declaration): Double-M4-quote those
- qualifiers here.
-
-2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
- unreliable -- especially when they're hidden inside another macro.
- * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
- data/c.m4: Remove m4_divert(-1).
- * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
- data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
- m4_divert_push(0) and m4_divert_pop(0).
- * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
- an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
- pushed and popped by m4sugar, should be first on the stack.
-
- Provide warn, complain, and fatal function callbacks to the skeletons.
- This provides more flexibility than m4_fatal, improves the error
- message format, and captures messages for translation. Discussed
- starting at
- <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
- * data/bison.m4 (b4_error): New, invoked by...
- (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
- skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
- directives. Because these M4 macros might be called when the current
- diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
- the previous removal of uses of m4_divert, which caused trouble.
- (b4_check_percent_code_qualifiers): Use b4_complain instead of
- m4_fatal to report unrecognized %code qualifiers.
- * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
- push parser requests.
- * data/glr.c: Use b4_complain instead of m4_fatal to report
- non-deterministic push parser requests.
- Update @output usage to @output(...@) form.
- * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
- report missing %defines. Update @output usage to @output(...@) form.
- * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
- @output(...@) form.
- * src/main.c (main): Invoke skel_scanner_free.
- * src/scan-skel.h (skel_scanner_free): Prototype new function.
- * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
- obstack_for_string from flex-scanner.h.
- (YY_DECL): Use to declare skel_lex static.
- (decode_at_digraphs): Remove; now handled in the new
- SC_AT_DIRECTIVE_ARG start condition.
- (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
- functions.
- (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
- at_directive_argv): New static globals.
- (INITIAL): Use fail_for_invalid_at.
- Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
- recognize the start of a generalized `@directive(...@)' form and
- start...
- (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
- directive args (using the new obstack_for_string), to decode the
- contained @ diagraphs, and to perform the directive. It recognizes
- @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
- @output(...@).
- (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
- SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
- `@,'.
- (scan_skel): Initialize obstack_for_string on the first call.
- (skel_scanner_free): New function to free obstack_for_string.
- * tests/input.at (Reject bad %code qualifiers): Update test output.
-
-2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Consolidate the 4 prologue alternative directives (%code, %requires,
- %provides, and %code-top) into a single %code directive with an
- optional qualifier field. Discussed at
- <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
- * NEWS (2.3a+): Rewrite the existing entry for the prologue
- alternatives.
- * doc/bison.texinfo (Prologue Alternatives): Update.
- (Decl Summary): Update to %code "requires" and %code "provides".
- (Calc++ Parser): Update to %code "requires".
- (Table of Symbols): Remove entries for %requires, %provides, and
- %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
- * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
- are replaced by b4_percent_code_provides and b4_percent_code_requires,
- which are skeleton-specific.
- (b4_check_percent_code_qualifiers): New. A skeleton can use this to
- declare what %code qualifiers it supports and to complain if any other
- qualifiers were used in the grammar.
- * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
- and b4_user_code([b4_percent_code_provides]) in place of
- b4_user_requires and b4_user_provides.
- * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
- Add b4_user_code([b4_percent_code_top]) and
- b4_user_code([b4_percent_code]).
- Invoke b4_check_percent_code_qualifiers.
- * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
- PERCENT_REQUIRES): Remove.
- (grammar_declaration): Remove RHS's for %code-top, %provides, and
- %requires. Rewrite the %code RHS as the unqualified form defining the
- muscle b4_percent_code. Add another RHS for the qualified %code form,
- which defines muscles of the form b4_percent_code_QUALIFIER and the
- b4_used_percent_code_qualifiers muscle.
- * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
- PERCENT_REQUIRES): Remove.
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
- %code "requires" and %code "provides".
- * tests/input.at (Reject bad %code qualifiers): New.
-
-2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Use the new code_props interface for destructors and printers.
- * src/symtab.h (symbol, semantic_type): Remove destructor_location and
- printer_location members, and change the type of the destructor and
- printer members to code_props.
- (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
- symbol_printer_get, semantic_type_destructor_set,
- semantic_type_printer_set, default_tagged_destructor_set,
- default_tagless_destructor_set, default_tagged_printer_set,
- default_tagless_printer_set): Use code_props in arguments and return
- types in place of char const * and location.
- (symbol_destructor_location_get, symbol_printer_location_get): Remove
- since the locations are now contained in the return of
- symbol_destructor_get and symbol_printer_get.
- * src/output.c (symbol_destructors_output, symbol_printers_output):
- Replace with...
- (symbol_code_props_output): ... this to eliminate duplicate code.
- (output_skeleton): Update to use symbol_code_props_output.
- * src/reader.c (symbol_should_be_used): Update use of
- symbol_destructor_get.
- * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
- Update uses of the various _destructor_set and _printer_set functions.
- * src/symtab.c: (default_tagged_destructor_location,
- default_tagless_destructor_location, default_tagged_printer_location,
- default_tagless_printer_location): Remove since we...
- (default_tagged_destructor, default_tagless_destructor,
- default_tagged_printer, default_tagless_printer): ... change the type
- of these to code_props.
- (symbol_new, semantic_type_new, symbol_destructor_set,
- semantic_type_destructor_set, symbol_destructor_get,
- symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
- symbol_check_alias_consistency, default_tagged_destructor_set,
- default_tagless_destructor_set, default_tagged_printer_set,
- default_tagless_printer_set): Update.
- (symbol_destructor_location_get, symbol_printer_location_get): Remove.
- (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
- code_props members.
- (symbol_print): Use SYMBOL_CODE_PRINT.
-
-2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Use the new code_props interface for rule actions.
- * src/symlist.h (symbol_list): Replace action, action_location, and
- used members with a code_props action_props member.
- * src/reader.c (symbol_should_be_used, grammar_rule_check,
- grammar_midrule_action, grammar_current_rule_merge_set,
- grammar_current_rule_symbol_append, packgram): Update.
- * src/scan-code.h (translate_rule_action): Remove, no longer used.
- * src/scan-code.l (handle_action_dollar): Update.
- (translate_rule_action): Remove, no longer used.
- * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
-
-2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Use the new code_props interface in parse-gram.y.
- * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
- Update all uses of translate_* functions to use the new code_props
- interface and to use gram_scanner_last_string_free and
- code_scanner_last_string_free where possible.
- (grammar_declaration): symbol_list_destructor_set and
- symbol_list_printer_set now perform the translation, so don't do it
- here. Use gram_scanner_last_string_free where possible.
- * src/scan-code.h, src/scan-code.l (translate_symbol_action,
- translate_code): Remove, no longer used.
- * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
- symbol_list_printer_set): Perform code translation here rather than
- depending on the caller to do so.
-
- * src/symlist.h (struct symbol_list): Correct some documentation typos.
- * src/scan-gram.h (gram_last_string): Remove declaration.
- * src/scan-gram.l (last_string): Declare it static.
-
-2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Encapsulate code properties and related functionality for the various
- destructors, printers, and actions into a code_props structure and
- interface. This patch merely implements code_props in scan-code.h and
- scan-code.l. Future patches will rewrite other modules to use it.
- Discussed starting at
- <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
- * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
- consistently initialize const structs that have an empty location
- field.
- * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
- to ensure consistency.
- * src/scan-code.h (code_props): New structure.
- (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
- function, macro, and const global variable for initializing a
- code_props with no code.
- (code_props_plain_init, code_props_symbol_action_init,
- code_props_rule_action_init, code_props_translate_code): The rest of
- the new code_props functional interface. Among other things, the init
- functions set the code_props kind field so that
- code_props_translate_code will know whether to behave like
- translate_symbol_action, translate_rule_action, or translate_code.
- These old translate functions must remain until all other modules are
- updated to use the new code_props interface.
- (code_scanner_last_string_free): New function similar to
- gram_scanner_last_string_free.
- (code_scanner_free): Add documentation.
- * src/scan-code.l: Implement the new interface.
- (code_lex): Make it static, add a code_props* argument, and remove the
- rule argument.
- (last_string): New static global similar to the one in scan-gram.l.
- (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
- instead of rule.
- (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
- code_props since Bison may one day use this information for destructors
- and printers.
- (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
- (handle_action_dollar): Use symbol_list_n_get and set used flag
- directly since symbol_list_n_used_set is removed.
- (translate_action): Add a code_props* argument and remove the rule,
- action, and location arguments. Pass the code_props* on to code_lex.
- (translate_rule_action, translate_symbol_action, translate_code):
- Rewrite as wrappers around the new code_props interface.
- * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
- it would eventually need to break the encapsulation of code_props.
-
-2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * etc/.cvsignore: New.
-
-2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Add maintainer-push-check to run maintainer-check using push parsing in
- place of pull parsing where available.
- * Makefile.am (maintainer-push-check): New.
- * data/bison.m4 (b4_use_push_for_pull_if): New.
- * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
- appropriately based on their existing values.
- (yypush_parse): Don't print push-parser-specific diagnostics if push
- parsing is being used in place of pull parsing.
- * data/yacc.c: If push parsing should replace pull parsing, redirect to
- push.c.
- * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
- variable, and insert b4_use_push_for_pull_flag into muscles.
- * tests/Makefile.am (maintainer-push-check): New.
-
-2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
- (whether successful or failed) so that yypush_parse can be invoked
- again to start a new parse using the same yypstate.
- * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
- check multiple yypull_parse invocations on the same yypstate. For pull
- mode, extend to check multiple yyparse invocations.
- (Exploding the Stack Size with Alloca): Extend to try with
- %push-pull-parser.
- (Exploding the Stack Size with Malloc): Likewise.
-
- * tests/calc.at (Simple LALR Calculator): Don't specify
- %skeleton "push.c" since %push-pull-parser implies that now.
- * tests/headers.at (export YYLTYPE): Don't check for the push
- declarations. Otherwise, this test case can't be used to see if push
- mode can truly emulate pull mode.
- * tests/input.at (Torturing the Scanner): Likewise.
- * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
- (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
- AT_YACC_IF, which now includes the case of push mode since %skeleton
- need not be used for push mode. This will be more intuitive once
- push.c is renamed to yacc.c.
-
-2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
-
- For push mode, convert yyparse from a macro to a function, invoke yylex
- instead of passing a yylexp argument to yypull_parse, and don't
- generate yypull_parse or yyparse unless %push-pull-parser is declared.
- Discussed starting at
- <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
- * data/bison.m4 (b4_pull_if): New.
- * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
- * data/push.c: Improve M4 quoting a little.
- (b4_generate_macro_args, b4_parenthesize): Remove.
- (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
- any time a pull parser is requested.
- Don't #define this as a wrapper around yypull_parse. Instead, when
- both push and pull are requested, make it a function that does that
- same thing.
- (yypull_parse): If there's a b4_prefix, #define this to
- b4_prefix[pull_parse] when both push and pull are requested.
- Don't define this as a function unless both push and pull are
- requested.
- Remove the yylexp argument and hard-code yylex invocation instead.
- * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
- %push-parser.
- * src/getargs.c (pull_parser): New global initialized to true.
- * getargs.h (pull_parser): extern it.
- * src/output.c (prepare): Insert pull_flag muscle.
- * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
- (prologue_declaration): Set both push_parser and pull_parser = true for
- %push-pull-parser. Set push_parser = true and pull_parser = false for
- %push-parser.
- * src/scan-gram.l: Don't accept %push_parser as an alternative to
- %push-parser since there's no backward-compatibility concern here.
- Scan %push-pull-parser.
- * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
- instead of %push-parser.
- * tests/headers.at (export YYLTYPE): Make yylex static, and don't
- prototype it in the module that calls yyparse.
- * tests/input.at (Torturing the Scanner): Likewise.
- * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
-
-2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Update etc/bench.pl. Optimize push mode a little (the yyn change
- deserves most of the credit).
- * Makefile.am (SUBDIRS): Add etc subdirectory.
- * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
- * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
- yytoken, yyval, and yyloc declarations to...
- (yyparse or yypush_parse): ... here to improve performance. For
- yypush_parse invocations after the first, be sure to assign yyn its old
- value again.
- (yypstate_new): Don't bother initializing the yyresult field since the
- initial value isn't used.
- (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
- remove the #define that, in push mode, set it to yyps->NAME.
- * etc/Makefile.am: New.
- * etc/bench.pl: Remove and build it instead from...
- * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
- "tests/bison" from the build directory by default rather than just
- invoking "bison" from $PATH.
- (calc_grammar): Update push parser code: don't declare yylval globally,
- don't define yyparse_wrapper, and don't #define yyparse.
- (bench_grammar): Update to check all working combinations of yacc.c,
- push.c, impure, pure, pull, and push.
-
-2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
-
- For push mode, add pull wrappers around yypush_parse.
- * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
- (yypull_parse): New function wrapping yypush_parse.
- (yyparse): New #define wrapping yypull_parse.
- * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
- is declared.
- * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
- prototype yylex in the module that calls yyparse, and don't prototype
- yyparse there. Otherwise, the yyparse expansion won't compile.
- * tests/input.at (Torturing the Scanner): Likewise.
-
-2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Enable push parsers to operate in impure mode. Thus, %push-parser no
- longer implies %pure-parser. The point of this change is to move
- towards being able to test the push parser code by running the entire
- test suite as if %push-parser had been declared.
- * data/push.c (yypush_parse): For impure mode, remove the
- yypushed_char, yypushed_val, and yypushed_loc arguments.
- Instead, declare these as local variables initialized to the global
- yychar, yylval, and yylloc.
- For the first yypush_parse invocation only, restore the initial values
- of these global variables when it's time to read a token since they
- have been overwritten.
- * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
- %push-parser.
- * tests/calc.at (Simple LALR(1) Calculator): Always declare
- %pure-parser along with %push-parser since this test case was designed
- for pure push parsers.
- * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
- (AT_YACC_OR_PUSH_IF): New.
- (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
- add a note that it's still wrong for some cases (as it has been for a
- while).
- (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
- %push-parser no longer implies %pure-parser.
-
-2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Remove some unnecessary differences between the pull parser code and
- the push parser code. This patch enables yynerrs in push mode.
- * data/push.c: Reformat M4 a little.
- (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
- (b4_declare_scanner_communication_variables): Don't omit yynerrs just
- because push mode is on. Instead, if pure mode is on, move yynerrs
- to...
- (b4_declare_parser_state_variables): ... here.
- (yynerrs, yyerror_range): For push mode, #define each NAME in this list
- to yyps->NAME so it can be used in yypush_parse.
- (yypush_parse): Don't omit uses of yynerrs in push mode.
-
-2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Fix bug such that the first pushed token's value and location are
- sometimes overwritten (sometimes by %initial-action) before being used.
- * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
- yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
- For the first yypush_parse invocation, initialize yychar to YYEMPTY to
- more closely mimic the pull parser logic.
- Don't copy the pushed token to yychar, yylval, and yylloc until it's
- time to read a token, which is after any initialization of yylval and

- (gottoken): Rename label to...
- (yyread_pushed_token): ... for clarity and to avoid infringing on the
- user namespace.

-2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Rearrange initialization of the parser state variables so that the
- skeleton doesn't have to have a copy for pull mode and another for push
- mode. This patch also fixes at least a bug such that yylloc was not
- initialized (with b4_location_initial_line and
- b4_location_initial_column) upon calling yypush_parse. However, that
- initialization now overwrites the first token's location;
- %initial-action assigning @$ already did the same thing, and both bugs
- will be fixed in a later patch.
- * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
- (b4_declare_parser_state_variables): Remove initialization of yytoken,
- yyss, yyvs, yyls, and yystacksize.
- (yypstate_new): Remove initialization of some yypstate fields: yystate,
- yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
- yylsp.
- (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
- yyps->NAME so it can be used in yypush_parse.
- (yyparse or yypush_parse): For yypush_parse, don't print the
- "Starting parse" diagnostic for invocations after the first.
- Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
- yypush_parse, only do it for the first invocation.
- Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
- initialization to occur in yypush_parse but only on the first
- invocation.
-
-2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * data/push.c: Add CPP guards around push parser declarations in both
- the header and the code file.
- In the code file, move the push parser declarations to the same place
- they appear in the header file.
- Clean up the M4 some, especially the inconsistent underquoting in
- some b4_c_function_def and b4_c_function_decl uses.
-
-2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Encapsulate the push parser state variables into an M4 macro so the
- push skeleton doesn't have to list them again for pull mode's yyparse.
- For push mode, remove yypush_parse's local equivalents of these
- variables to eliminate unnecessary copying between the two sets at
- run-time. This patch also fixes at least a bug related to multiple
- %initial-action invocations in push mode.
- * data/push.c (b4_declare_parser_variables): Rename to...
- (b4_declare_scanner_communication_variables): ... this for clarity and
- update both uses.
- (b4_declare_yyparse_variables): Remove and move its contents to the one
- spot where it was invoked.
- (b4_declare_parser_state_variables): New macro containing the parser
- state variables required by push mode.
- (struct yypstate): Replace all fields but yynew with
- b4_declare_parser_state_variables.
- (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
- yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
- each NAME in this list to yyps->NAME so it can be used in yypush_parse.
- (yyparse or yypush_parse): For yyparse in pull mode, replace local
- parser state variable declarations with
- b4_declare_parser_state_variables.
- Don't initialize parser state variables when calling yypush_parse since
- yypstate_new already does that.
- Invoke the user's initial action only upon the first yypush_parse
- invocation.
- Remove all code that copies between the local parser state variables
- and the yypstate.
-
-2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
- prevent a name collision in a future patch where these names will
- sometimes be #define'd.
- (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
- since it no longer has the same name as the existing argument.
- (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.

- * doc/bison.texinfo (Decl Summary): In the %language entry, mention
- that the argument is case-insensitive, and there's no `=' here.
- For the %skeleton entry, mention that %language is better.
- (Bison Options): Likewise for --language and --skeleton. Move the
- --skeleton entry so that the `Tuning the parser' section is sorted

- (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
- `%require "2.3b"' so that the example is always up-to-date.
- (Table of Symbols): Add entries for %language and %skeleton.
- * examples/extexi (normalize): Instead of replacing every %require
- argument with the current Bison version, just substitute for
- `@value{VERSION}'. This guarantees that we're testing what actually
- appears in the documentation.
- * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'

-
- * TODO: Add pointer to Sylvain Schmitz's work on static detection
- of potential ambiguities in GLR grammers.
-
-2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
- `bison ', use m4_index instead of m4_substr since chopping up a string
- containing M4-special characters causes problems here.
-
- Fix a couple of bugs related to special characters in user-specified
- file names, and make it easier for skeletons to compute output file
- names with the same file name prefix as Bison-computed output file
- names.
- * data/glr.cc, data/push.c, data/yacc.c: In @output, use
- b4_parser_file_name and b4_spec_defines_file instead of
- @output_parser_name@ and @output_header_name@, which are now redundant.
- * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
- b4_parser_file_name, b4_spec_defines_file, and the new
- @basename(FILENAME@) instead of @output_parser_name@ and
- @output_header_name@, which inappropriately escaped the file names as
- C string literals.
- * src/files.c (all_but_ext): Remove static qualifier.
- (compute_output_file_names): Move `free (all_but_ext)' to...
- (output_file_names_free): ... here since all_but_ext is needed later.
- * src/files.h (all_but_ext): Extern.
- * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
- exactly what MUSCLE_INSERT_STRING used to do.
- (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
- characters are escaped properly.
- * src/output.c (prepare): Define muscle file_name_all_but_ext as
- all_but_ext.
- For pkgdatadir muscle, maintain previous functionality by using
- MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
- is that b4_pkgdatadir is used inside m4_include in the skeletons, so
- digraphs would never be expanded. Hopefully no one has M4-special
- characters in his Bison installation path.
- * src/scan-skel.l: Don't parse @output_header_name@ and
- @output_parser_name@ anymore since they're now redundant.
- In @output, use decode_at_digraphs.
- Parse a new @basename command that invokes last_component.
- (decode_at_digraphs): New.
- (BASE_QPUTS): Remove unused.
- * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
- (Output file name): New tests.

-2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Finish implementing --warnings=error, which should not be implied by
- --warnings=all (or by its synonyms -W and --warnings without

- warnings are being treated as errors and to record an error if so.
- Invoke...
- (warn_at, warn): ... here.
- * src/getargs.c (warnings_args, warnings_types): Reorder so that
- "error - warnings are errors" does not appear above "all - all of the
- above".

-
- * data/push.c, data/yacc.c: Make sure there's a newline at the end of
- the parser header file so that gcc doesn't warn.

- SYMLIST_DEFAULT_TAGGED and SYMLIST_DEFAULT_TAGLESS.
- * src/symtab.c (default_destructor, default_destructor_location,
- default_printer, default_printer_location): Split each into tagged and
- tagless versions.
- (symbol_destructor_get, symbol_destructor_location_get,
- symbol_printer_get, symbol_printer_location_get): Implement tagged
- default and tagless default cases.
- (default_destructor_set, default_printer_set): Split each into tagged
- and tagless versions.
- * src/symtab.h: Update prototypes.

- $n usage.
- (packgram): Before invoking grammar_rule_check on any rule, make sure
- all actions have already been scanned in order to set `used' flags.
- Otherwise, checking that a midrule's $$ is set will not always work
- properly because the midrule check must forward-reference the midrule's
- parent rule.
- * tests/input.at (AT_CHECK_UNUSED_VALUES): Extend to check the new
- warning.
-
-2006-10-20 Joel E. Denny <jdenny@ces.clemson.edu>

- sticks with the automake default in generating dependencies.
-
-2006-10-12 Paul Eggert <eggert@cs.ucla.edu>

-
- 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
-
- * bootstrap (symlink_to_gnulib): New function.
- (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
- to copies-of-gnulib.
- (cp_mark_as_generated, slurp, gnulib_files):
- Avoid making a copy if it's the same as the old version.
- (gnulib_files): Add support for this variable (used by Bison).
-
-2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
-
- * src/getargs.c (usage): Rework to use conventions similar to

- (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
- * src/system.h: Include inttypes.h unconditionally, now that we

- * src/main.c: Likewise.
- * src/output.c: Likewise.

- before declarations; it's not portable to C89.
- * src/scan-code.l (handle_action_at): Likewise.
-
- * src/scan-code.l: Always initialize braces_level; the old code
- left it uninitialized and therefore had undefined behavior.
-
- Don't attempt to redefine 'assert', since it runs afoul of
- systems where standard headers (mistakenly) include <assert.h>.
- Instead, define and use our own alternative, called 'aver'.
- * src/reader.c: Don't include assert.h, since we no longer
- use assert.
- * src/scan-code.l: Likewise.
- * src/system.h (assert): Remove, replacing with....
- (aver): New function, taking a bool arg. All uses changed.
- * src/tables.c (pack_vector): Ensure that aver arg is bool,

-
-2006-09-13 Paul Eggert <eggert@cs.ucla.edu>

-
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
- "#define YYSTYPE int" that caused "make maintainer-check" to fail
- due to header ordering dependencies. I don't know why the #define
- was there.
-
- Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
- runtime cost when YYDEBUG is not defined, and so that some tests
- that used to fail now work. Problem and initial suggestion by
- Paolo Bonzini.
- * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
- * data/glr.cc (b4_parser_class_name):

- set_debug_level.
- * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
- * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
- AT_CHECK_CALC_GLR_CC that are working now.
-
-2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
- We don't need them in glr.cc, and glr.c defines them.
- Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c

- it to 1. Problem reported by Paolo Bonzini.
-
-2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
-
- * data/c.m4 (b4_null, b4_case): Define.
- * src/output.c (prepare_symbols): Use b4_null.
- (user_actions_output): Use b4_case.
-
-2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/glr.c (b4_shared_declarations): Put start-header first,
- before any #includes that we generate, so that feature-test
- macros work. Problem reported by Michael Deutschmann in
- <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
- * data/lalr1.cc: Likewise.
- * doc/bison.texinfo (Prologue): Document that feature-test macros
- should be defined before any Bison declarations.
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
- that depend on location.hh after, not before, Bison decls, since
- we now include location.hh after the first user prologue.
-
- * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
- Sander Brandenburg in
- <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
- Also, fix minor white space and comment issues.
- (Prologue): Mention that it's better to define feature-test macros
- before Bison declarations. Problem reported by Michael Deutschmann.
-
- * README-cvs: Fix typo: "&" should be "&&". Problem reported
- by Jim Meyering.
- * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
- This adjusts to recent gnulib changes.

-2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Finish implementation of per-type %destructor/%printer. Discussed
- starting at
- <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
- and
- <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
- * NEWS (2.3+): Add a description of this feature to the default
- %destructor/%printer description.
- * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
- * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
- Invoke semantic_type_destructor_set or semantic_type_printer_set when a
- list node contains a semantic type.
- * src/symtab.c, src/symtab.h: Extend with a table that associates
- semantic types with their %destructor's and %printer's.
- (semantic_type_from_uniqstr, semantic_type_get,
- semantic_type_destructor_set, semantic_type_printer_set): New functions
- composing the public interface of that table.
- (symbol_destructor_get, symbol_destructor_location_get,
- symbol_printer_get, symbol_printer_location_get): If there's no
- per-symbol %destructor/%printer, look up the per-type before trying
- the default.
- * tests/actions.at (Per-type %printer and %destructor): New test case.
- * tests/input.at (Default %printer and %destructor redeclared):
- Extend to check that multiple occurrences of %symbol-default in a
- single %destructor/%printer declaration is an error.
- (Per-type %printer and %destructor redeclared, Unused values with
- per-type %destructor): New test cases.
-
-2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Require default %destructor/%printer to be declared using
- %symbol-default instead of an empty symbol list, and start working on
- new per-type %destructor/%printer. Discussed at
- <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
- * NEWS (2.3+): Add %symbol-default to example.
- * bison.texinfo (Freeing Discarded Symbols): Likewise.
- (Table of Symbols): Add entry for %symbol-default.
- * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
- (generic_symlist, generic_symlist_item): New nonterminals for creating
- a list in which each item is a symbol, semantic type, or
- %symbol-default.
- (grammar_declaration): Use generic_symlist in %destructor and %printer
- declarations instead of symbols.1 or an empty list.
- (symbol_declaration, precedence_declaration, symbols.1): Update actions
- for changes to symbol_list.
- * src/reader.c: Update for changes to symbol_list.
- * src/scan-code.l: Likewise.
- * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
- * src/symlist.c, src/symlist.h: Extend such that a list node may
- represent a semantic type or a %symbol-default in addition to just an
- ordinary symbol. Add switched functions for setting %destructor's and
- %printer's.
- * tests/actions.at, tests/input.at: Add %symbol-default to all default
- %destructor/%printer declarations.
-
-2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Whether the default %destructor/%printer applies to a particular symbol
- isn't a question of whether the user *declares* that symbol (in %token,
- for example). It's a question of whether the user by any means
- *defines* the symbol at all (by simply using a char token, for
- example). $end is defined by Bison whereas any other token with token
- number 0 is defined by the user. The error token is always defined by
- Bison regardless of whether the user declares it with %token, but we
- may one day let the user define error as a nonterminal instead.
- * NEWS (2.3+): Say "user-defined" instead of "user-declared".
- * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
- the meaning of "user-defined".
- * tests/actions.at (Default %printer and %destructor for user-declared
- end token): Rename to...
- (Default %printer and %destructor for user-defined end token): ...
- this.
-
- * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
- computation of whether to apply the default, don't maintain a list of
- every Bison-defined symbol. Instead, just check for a first character
- of '$', which a user symbol cannot have, and check for the error token.
-
-2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Don't apply the default %destructor or %printer to the error token,
- $undefined, or $accept. This change fits the general rule that the
- default %destructor and %printer are only for user-declared symbols,
- and it solves several difficulties that are described in the new test
- cases listed below.
- * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
- * tests/actions.at (Default %printer and %destructor are not for error
- or $undefined, Default %printer and %destructor are not for $accept):
- New test cases.
-
-2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Allow %start after the first rule.
- * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
- when parsing the first rule.
- (check_and_convert_grammar): Search for it here after all grammar
- declarations have been parsed. Skip midrules, which have dummy LHS
- nonterminals.
- * src/symtab.c (symbol_is_dummy): New function.
- * src/symtab.h (symbol_is_dummy): Declare it.
- * tests/input.at (%start after first rule): New test.
-
-2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Redo some of the previous commit: add back the ability to use
- non-aliased/undeclared string literals since it might be useful to
- those declaring %token-table.
- * src/reader.c (check_and_convert_grammar): Undo changes in previous
- commit: don't worry about complaints from symbols_pack.
- * src/symtab.c (symbol_new, symbol_class_set,
- symbol_check_alias_consistency): Undo changes in previous commit: count
- each string literal as a new symbol and token, assign it a symbol
- number, and don't complain about non-aliased string literals.
- (symbols_pack): Since symbol_make_alias still does not decrement symbol
- and token counts but does still set aliased tokens to the same number,
- symbol_pack_processor now leaves empty slots in the symbols array.
- Remove those slots.
- * tests/regression.at (Undeclared string literal): Remove test case
- added in previous commit since non-aliased string literals are allowed
- again.
- (Characters Escapes, Web2c Actions): Undo changes in previous commit:
- remove unnecessary string literal declarations.
- * tests/sets.at (Firsts): Likewise.
-
-2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Don't allow an undeclared string literal, but allow a string literal to
- be used before its declaration.
- * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
- symbols_pack complained.
- * src/symtab.c (symbol_new): Don't count a string literal as a new
- symbol.
- (symbol_class_set): Don't count a string literal as a new token, and
- don't assign it a symbol number since symbol_make_alias does that.
- (symbol_make_alias): It's not necessary to decrement the symbol and
- token counts anymore. Don't assume that an alias declaration occurs
- before any uses of the identifier or string, and thus don't assert that
- one of them has the highest symbol number so far.
- (symbol_check_alias_consistency): Complain if there's a string literal
- that wasn't declared as an alias.
- (symbols_pack): Bail if symbol_check_alias_consistency failed since
- symbol_pack asserts that every token has been assigned a symbol number
- although undeclared string literals have not.
- * tests/regression.at (String alias declared after use, Undeclared
- string literal): New test cases.
- (Characters Escapes, Web2c Actions): Declare string literals as
- aliases.
- * tests/sets.at (Firsts): Likewise.
-
-2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
-
- In the grammar scanner, STRING_FINISH unclosed constructs and return
- them to the parser in order to improve error messages.
- * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
- SC_BRACED_CODE, SC_PROLOGUE): Implement.
- * tests/input.at (Unclosed constructs): New test case.
- * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
- seen.
-
- * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
- unused global.
-
-2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Handle string aliases for character tokens correctly.
- * src/symtab.c (symbol_user_token_number_set): If the token has an
- alias, check and set its alias's user token number instead of its own,
- which is set to indicate the alias. Previously, every occurrence of
- the character token in the grammar overwrote that alias indicator with
- the character code.
- * tests/input.at (String aliases for character tokens): New test.
-
-2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
-
-2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
-
- * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
- to prevent failures when building on older platforms.
- Check for autopoint failure.
- Set XGETTEXT_OPTIONS to values that check for C format strings,
- so that translators are warned about them (this also helps
- prevent core dumps).
-
- * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
- function, since it simplifies our code a bit.
-
- * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
- rather than -W, so we don't get bogus warnings about sign comparisons.
- Add -Wpointer-arith, since that warning is useful (it reports code
- that does not conform to C89 and that some compilers reject).
- * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
- since it's no longer needed.
-
-2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Clean up scanners a bit.
- * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
- definitions so gcc won't warn when obstack_for_string is unused.
- * src/scan-code.l: config.h and system.h are already #include'd by
- scan-code-c.c, so get rid of them here.
- * src/scan-gram.l: Likewise.
- * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
- definitions rather than duplicating the rest of it.
- * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
-
-2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Suppress signed/unsigned comparison warnings for yycheck.
- * data/c.m4 (b4_safest_int_type): New macro.
- * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
- a signed int type, cast it to b4_safest_int_type first.
- * data/yacc.c: Likewise.
- (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
- also overwritten.
-
-2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
-
- * doc/bison.texinfo: Fix some typos.
-
-2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
-
- * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
- po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
-
- * bootstrap (gnulib_tool): Stop using --assume-autoconf;
- the latest gnulib does this a different way.
- (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
- translation was patched, so stop omitting it.
-
-2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Enable declaration of default %printer/%destructor. Make the parser
- use these for all user-declared grammar symbols for which the user does
- not declare a specific %printer/%destructor. Thus, the parser uses it
- for token 0 if the user declares it but not if Bison generates it as
- $end. Discussed starting at
- <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
- <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
- and
- <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
- * NEWS (2.3+): Mention.
- * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
- declare a %destructor for a mid-rule's semantic value. It's just
- impossible to declare one specific to it.
- (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
- code. Describe default %destructor form.
- * src/parse-gram.y (grammar_declaration): Parse default
- %printer/%destructor declarations.
- * src/output.c (symbol_destructors_output): Use symbol_destructor_get
- and symbol_destructor_location_get rather than accessing the destructor
- and destructor_location members of struct symbol.
- (symbol_printers_output): Likewise but for %printer's.
- * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
- again.
- * src/symtab.c (default_destructor, default_destructor_location,
- default_printer, default_printer_location): New static global
- variables to record the default %destructor and %printer.
- (symbol_destructor_get, symbol_destructor_location_get,
- symbol_printer_get, symbol_printer_location_get): New functions to
- compute the appropriate %destructor and %printer for a symbol.
- (default_destructor_set, default_printer_set): New functions to set the
- default %destructor and %printer.
- * src/symtab.h: Prototype all those new functions.
- * tests/actions.at (Default %printer and %destructor): New test to
- check that the right %printer and %destructor are called, that they're
- not called for $end, and that $$ and @$ work correctly.
- (Default %printer and %destructor for user-declared end token): New
- test to check that the default %printer and %destructor are called for
- a user-declared end token.
- * tests/input.at (Default %printer and %destructor redeclared, Unused
- values with default %destructor): New tests to check related grammar
- warnings and errors.
-
-2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Clean up handling of %destructor for the end token (token 0).
- Discussed starting at
- <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
- and
- <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
-
- Make the skeletons consistent in how they pop the end token and invoke
- its %destructor.
- * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
- state, which has token number 0, since this would invoke the
- %destructor for the end token.
- * data/lalr1.cc (yy::parser::parse): Don't check for the final state
- until after shifting the end token, or else it won't be popped.
- * data/yacc.c (yyparse): Likewise.
-
- * data/glr.c (yyparse): Clear the lookahead after shifting it even when
- it's the end token. Upon termination, destroy an unshifted lookahead
- even when it's the end token.
- * data/lalr1.cc (yy::parser::parse): Likewise.
- * data/yacc.c (yyparse): Likewise.
-
- * src/reader.c (packgram): Don't check rule 0. This suppresses unused
- value warnings for the end token when the user gives the end token a
- %destructor.
-
- * tests/actions.at (Printers and Destructors): Test all the above.
-
-2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
-
- Update to latest gnulib and gettext versions.
- * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
- Add fopen-safer.
- (gnulib_files): Add m4/warning.m4. Don't worry about files
- overwritten by autopoint.
- Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
- Suppress "id", "ms", "tr" translations for now, since gettext 0.15
- rejects them.
- Don't use autoreconf; instead, invoke autopoint etc. by hand,
- so that we can remove the intl files at a better time.
- (intl_files_to_remove): Remove aclocal.m4, since it gets
- rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
- m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
- m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
- Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
- Remove datarootdir hack; no longer needed.
- * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
- (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
- * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
- strdup.h.
- * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
- * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
-
-2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
-
- * bootstrap: Adjust to today's change to gnulib-tool by invoking
- it with --assume-autoconf='latest-stable'.
-
-2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
- least 1.4.7 and 1.4.4) by putting a #line between `typedef union
- YYSTYPE' and `{'.
- * src/muscle_tab.h (muscle_grow): Replace the header comments with
- those from muscle_tab.c since the old ones are misleading.
-
-2006-07-13 Akim Demaille <akim@epita.fr>
-
- Support %define "KEY" {VALUE}.
- * src/scan-code.h, src/scan-code.l (translate_action)
- (translate_rule_action, translate_symbol_action, translate_code):
- Return char *, not const char *.
- * src/parse-gram.y (declaration): Rename as...
- (prologue_declaration): this.
- (string_content): Remove this nonterminal, use STRING.
- (braceless, content, content.opt): New nonterminal.
- Use them.
- (%define): Now accept content.opt, i.e., accept also BRACED_CODE
- as value.
- * src/scan-gram.l (getargs.h): Don't include it.
-
-2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
- rather than a for-loop that declares a local bool variable. This
- should work around a compatibility problem with a Cray x1e C++
- compiler reported by Hung Nguyen in
- <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
- The for-loop was introduced in the 2004-11-17 change but I don't
- know why it was needed.
-
-2006-07-12 Akim Demaille <akim@epita.fr>
-
- * data/c.m4: Comment changes.
-
-2006-07-10 Akim Demaille <akim@lrde.epita.fr>
-
- * src/complain.c (error_message, ERROR_MESSAGE): New.
- To factor...
- (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
- * src/complain.h, src/complain.c (warning_issued): Remove, unused.
-
-2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
-
- * NEWS: Instead of %union, you can define and use your own union type
- YYSTYPE if your grammar contains at least one <type> tag.
- Your YYSTYPE need not be a macro; it can be a typedef.
- * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
- (Union Decl, Decl Summary): Document this.
- * data/glr.c (YYSTYPE): Implement this.
- * data/glr.cc (YYSTYPE): Likewise.
- * data/lalr1.cc (YYSTYPE): Likewise.
- * data/yacc.c (YYSTYPE): Likewise.
- * src/output.c (prepare): Output tag_seen_flag.
- * src/parse-gram.y (declaration, grammar_declaration):
- Use 'union_seen' rather than 'typed' to determine whether
- %union has been seen, since grammars can now be typed without
- %union.
- (symbol_declaration, type.opt, symbol_def):
- Keep track of whether a tag has been seen.
- * src/reader.c (union_seen, tag_seen): New vars.
- (typed): remove.
- * src/reader.h (union_seen, tag_seen, typed): Likewise.
- * src/scan-code.l (untyped_var_seen): New variable.
- (handle_action_dollar): Adjust to above changes.
- (handle_action_dollar, handle_action_at):
- Improve overflow checking for outlandish numbers.
- * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
- avoid new diagnostics generated by above changes.
- * tests/regression.at (YYSTYPE typedef): Add test to check
- for type tags without %union.
-
- * src/symlist.c (symbol_list_length): Return int, not unsigned
- int, since callers expect int. This may need to get revisited
- once we have proper integer overflow checking.
-
- * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
- object is now static.
-
- * src/getargs.c (flags_argmatch): Return void, not int,
- to pacify ./configure --enable-gcc-warnings.
-
- * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
- since last_string is already defined to FLEX_PREFIX (last_string).
-
-2006-07-09 Akim Demaille <akim@lrde.epita.fr>
-
- Implement --warnings/-W.
- * src/getargs.c (report_argmatch, trace_argmatch): Remove,
- replaced by...
- (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
- Adjust callers.
- * src/getargs.h, src/getargs.c (warnings, warnings_flags)
- (warnings_args, warnings_types): New.
- (getargs, short_options, long_options): Accept -W/--warnings.
- Sort the options by alphabetical order, upper case letter right
- before its lower case.
-
-2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Change %merge result type clash warnings to errors. Discussed at
- <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
- * src/reader.c (record_merge_function_type): Use complain_at.
- * tests/glr-regression.at (Missed %merge type warnings when LHS type is
- declared later): Update test case results.
-
-2006-07-09 Akim Demaille <akim@lrde.epita.fr>
-
- * src/getargs.h, src/getargs.c: Swap --report and --trace handling
- to be in alphabetical order.
- (trace_args): Spelling fixes.
-
-2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
- so they don't collide with user-defined macros.
- (yy_stack_print): Don't assume that yytype_int16 promotes to int;
- this was never guaranteed, and now that we're using gnulib stdint,
- which defines int_fast16_t to long int, the problem is exposed.
-
-2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/c.m4 (b4_basename): Simplify a bit, since we don't
- need the full POSIX semantics (and weren't implementing them
- anyway).
-
- Adjust to Autoconf 2.60 and today's gnulib.
- * bootstrap (gnulib_modules): Add stdint.
- Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
- no longer copies it.
- (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
- since stdint needs the former and wcwidth (which is now required

- Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
- work around a compatibility glitch between gettext 0.14.6 and
- Autoconf 2.60.
- * configure.ac (AC_PREREQ): Require Autoconf 2.60.
- Do not check for uintptr_t, since new stdint module does the right

-2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
-
- In warnings, say "previous declaration" rather than "first
- declaration".
- * src/symtab.c (redeclaration): Do that here.
- * src/reader.c (record_merge_function_type): In the case of a result
- type clash, report the previous declaration rather than the very first
- one in the grammar file.

-2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Don't miss %merge result type warnings just because the LHS types are
- declared after the %merge. This continues the effort of the previous
- patch.
- * src/reader.c (get_merge_function): Don't set the merger type yet.
- (record_merge_function_type): New function for setting the merger type
- and checking for clashes.
- (grammar_current_rule_merge_set): Set the location of the %merge for
- the current rule.
- (packgram): Invoke record_merge_function_type for each rule now that

- Get action warnings (grammar_rule_check) right even when symbol
- declarations appear after the rules. Discussed at

- and
- <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
- Don't mistake the type of $$ in a midrule to be that of its parent
- rule's $$.
- * src/reader.c (grammar_current_rule_end): Don't invoke
- grammar_rule_check yet since not all symbol declarations may have been
- parsed yet.
- (grammar_midrule_action): Likewise.
- Don't record whether the midrule's $$ has been used yet since actions
- haven't been translated yet.
- Record the midrule's parent rule and its RHS index within the parent
- rule.
- (grammar_current_rule_action_append): Don't translate the action yet
- since not all symbol declarations may have been parsed yet and, thus,
- warnings about types for $$, $n, @$, and @n can't be reported yet.
- (packgram): Translate the action and invoke grammar_rule_check now that
- all symbol declarations have been parsed.
- * src/scan-code.l (handle_action_dollar): Now that this is invoked
- after parsing the entire grammar file, the symbol list here in the case
- of a midrule is actually the midrule's empty RHS, so reference its
- parent rule's RHS where necessary.
- On the other hand, now that you can already know it's a midrule, you
- aren't forced to think $$ has the same type as its parent rule's $$.
- (handle_action_at): In the case of a midrule, reference the parent rule
- where necessary.
- * src/symlist.c (symbol_list_new): Initialize new midrule-related
- members.
- (symbol_list_length): Now that this is invoked after all rules have
- been parsed, a NULL symbol (rather than a NULL symbol list node)
- terminates a rule. symbol_list_print already does this correctly.
- * src/symlist.h (symbol_list.midrule_parent_rule,
- symbol_list.midrule_parent_rhs_index): New members so that midrules can
- remember their relationships with their parents.
- * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
- fixed by the above patch.
- (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
- implementing...
- (Unused values): ... this old test case and...
- (Unused values before symbol declarations): ... this new test case.
- This one is the same as `Unused values' except that all symbol
- declarations appear after the rules in order to catch the rest of the
- errors fixed by the above patch.

- * src/reader.h (current_rule): Remove this unused extern.
- * src/scan-code.h (translate_rule_action): Remove redundant arguments.

- Make yyerror and yylex static as usual.
-
-2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Fix bug that mistakes braced code in a declaration in the rules section
- to be a rule action. Mentioned at
- <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
- * src/scan-gram.l: Move midrule action detection from the start of the
- scanning of any braced code to...
- * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
- action. For readability, use $2 and @2 rather than the equivalent
- global variables.
- * tests/regression.at (Braced code in declaration in rules section):
- New test to catch the error fixed by the above patch.
-
- Work on code readability some.
- * src/scan-code.l (current_rule): Get rid of this misleading and
- redundant declaration: it's actually extern'ed in reader.h.
- (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
- translate_action): Add a rule argument and use it instead of the global
- current_rule.
- (translate_rule_action): This already receives current_rule through an
- argument, so pass it on to translate_action instead of assigning
- current_rule to current_rule.
- (translate_symbol_action, translate_code): Pass rule = NULL to
- translate_action.

- Don't put the pre-prologue in the header file. For the yacc.c code
- file and the glr.c header and code files, move the pre-prologue before
- the token definitions. Add new %before-definitions and
- %after-definitions to declare code that will go in both the header file
- and code file. Discussed at

- (b4_token_enums_defines): In the code file, move to right before
- YYSTYPE for consistency with the header file.
- (b4_before_definitions): New right before b4_token_enums_defines in
- both the header and code file.
- (b4_after_definitions): New right after YYLTYPE and yylloc in both the
- header and code file.

- of prologues for %union dependencies.
- (Decl Summary): In %defines description, mention the effect of
- %before-definitions and %after-definitions on the header file.

- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
- prologue block in a %before-definitions or a %after-definitions based
- on whether the %union is declared.
- * tests/regression.at (Early token definitions with --yacc, Early token
- definitions without --yacc): Move tests for token definitions into the
- post-prologue since token names are no longer defined in the

-
- The Translation Project changed its way of publishing translations
- to maintainers. I haven't received any responses to my request
- for supporting the old way, or for documenting the new way. I
- have modified 'bootstrap' to use screen scraping
- (in this case, HTML scraping). This is unreliable and inelegant,
- but I don't see any better way. Yuck.
- * bootstrap (TP_URL, WGET_COMMAND): New vars.
- (get_translations): New function, which uses HTML scraping to
- deduce locations of latest translations.
- Use this function to grab both bison and bison-runtime .po files.
- Don't bother priming the pump for the runtime-po domain any more,
- as it's now translated better than bison is.
-
-2006-06-19 Akim Demaille <akim@epita.fr>
-
- * src/scan-gram.l: No longer "parse" things after `%union' until

- Remove this test case and copy to...
- (Early token definitions with --yacc): ... this to test #define's.
- (Early token definitions without --yacc): ... and this to test enums.

-
-2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Between Bison releases, manually append `+' to the previous Bison
- release number, and use that as a signal to automatically print the
- ChangeLog's CVS Id keyword from --version. Discussed starting at
- <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
- * ChangeLog: Add Id header.
- * configure.ac (AC_INIT): Append `+' to `2.3'.
- * src/.cvsignore: Add revision.c.
- * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
- (BUILT_SOURCES): Add revision.c.
- (revision.c): New target rule. This file defines a new global variable
- named revision. It initializes it with either the Id from ChangeLog
- or, if VERSION doesn't contain `+', with the empty string.
- * src/getargs.c (version): Print the value of revision.
- * src/revision.h: Extern revision.

-2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/glr.c (YYRECOVERING): Define to be a function-like macro
- with no arguments, not as an object-like macro. This is for
- compatibility with data/yacc.c. Problem reported by John P. Hartmann in
- <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
- * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
- Document this.
-
-2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * src/getargs.c (usage): Back out yesterday's modification of the
- --help output so that we don't have to wait for translation before
- releasing 2.3.
-
-2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
-

- generated source code. Problem reported by Frans Englich in
- <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
-
-2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
-
- * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
- shell, not within 'make', so that 'make' by an ordinary builder
- (using GNU make) does not worry about configuring gzip. This also
- works around a bug reported independently by Keith Thompson and by
- Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
- stderr rather than stdout, messing up the build logs.
-
-2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
- to make sure that YYID will never be unused. This fixes a 'make
- maintainer-check' failure caused by the recent changes to the 'Trivial
- grammars' test case, which caused g++ 4.1.0 to complain that YYID was
- not used.
- * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
-
-2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
- state before an empty RHS is always resolved here. Only the location
- of that state is guaranteed to be resolved, and that's enough. This
- fixes the remaining bug reported by Derek M. Jones in
- <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
- * tests/glr-regression.at (Uninitialized location when reporting
- ambiguity): Test the above case.
- Also, the embedded comments in this test case claim it checks the case
- of an empty RHS that has inherited the initial location. However, the
- corresponding LHS was already resolved, so yyresolveLocations didn't
- actually have reason to modify it. Fix this by forcing
- nondeterministic operation at the beginning of the parse.
-
-2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/c.m4 (b4_yy_symbol_print_generate):
- (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
- 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
- of the bugs reported today by Derek M Jones in
- <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
- * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
- defined to be a type name without parens or brackets.
- (Location Type): Similarly for YYLTYPE.
- * tests/regression.at (Trivial grammars): Put in a test for this
- bug that will be caught by 'make maintainer-check' (though not,
- alas, by 'make check' unless your compiler is picky).
-
-2006-05-19 Paul Eggert <eggert@cs.ucla.edu>

-
-2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * data/glr.c (yyreportTree): Make room in yystates for the state
- preceding the RHS. This fixes the segmentation fault reported by Derek
- M. Jones in
- <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
- (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
- to the user. Reported for yyreportTree by Derek M. Jones later in the
- same thread.
- * THANKS: Add Derek M. Jones.
- Update my email address.
- Fix typo in Steve Murphy's name.
-
-2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
- checking against YYLAST that caused the parser to miss a potential
- alternative in its diagnostic.
- Problem reported by Maria Jose Moron Fernandez in
- <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
- * data/lalr1.cc (yysyntax_error_): Likewise.
- * data/yacc.c (yysyntax_error): Likewise.
- * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
- tokens, in case we run into an older C compiler.
- (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
- Use them to check for the off-by-one error fixed above.
-
- * data/yacc.c (yytnamerr): Fix typo: local var should be of type
- YYSIZE_T, not size_t.
- * tests/regression.at (Trivial grammars): New test, to catch
- the error fixed by the above patch.
-
-2006-05-14 Akim Demaille <akim@lrde.epita.fr>

-
- Implement --trace=m4.
- * src/getargs.c (trace_types, trace_args): Accept trace_m4.
- * src/output.c (output_skeleton): When set, pass -dV to m4.

- * data/c.m4: Adjust.
- (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
- Use b4_define_flag_if to define other b4_FLAG_if macros.

- (b4_locations_if): this, for consistency.
- Adjust all the skeletons.
-

- Sort the flags.
- Adjust dependencies.
-
-2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/c.m4 (b4_copyright): Put the special exception for Bison
- skeletons here, so we don't have to put it in each skeleton. All
- uses changed. Suggested by Akim Demaille. Also, wrap the
- copyright notice, in case it is longer than 80 columns. Replace
- comma by newline after title.
-
-2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
-
- * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an

-2006-03-12 Akim Demaille <akim@lrde.epita.fr>
-
- * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
- of AT_NAME_PREFIX when %name-prefix is not used.
-
-2006-03-12 Akim Demaille <akim@lrde.epita.fr>
-
- Apply --prefix to C++ skeletons too: they change the namespace.
- The test suite already exercize these cases.
- * data/c++.m4 (b4_namespace): New.
- * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.

-2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web

-
-2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/glr.c (yyresolveLocations): Rename local variables to avoid
- shadowing warnings. Use usual patter for iterating through RHS.
- * tests/glr-regression.at
- (Uninitialized location when reporting ambiguity):
- Modify yylex so that it uses its argument, rather than trying
- to rely on ARGSUSED (which doesn't work for gcc with warnings).
- const char -> char const.
-
- * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
- Don't use tabs inside commands; it messes up 'ps'.

-
- * tests/glr-regression.at (Uninitialized location when reporting

- * doc/bison.texinfo (Default Action for Locations): Note
- YYLLOC_DEFAULT's usage for ambiguity locations.
- (GLR Semantic Actions): Cross-reference those notes.
-
-2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * tests/glr-regression.at (Leaked semantic values when reporting
- ambiguity): Remove unnecessary union and type declarations.
- (Leaked lookahead after nondeterministic parse syntax error): New test
- case.
- * data/glr.c (yyparse): Check for zero stacks remaining before
- attempting to shift the lookahead so that you don't lose it.
-
-2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
- * tests/glr-regression.at (Leaked semantic values when reporting
- ambiguity): New test case.
- * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
- yyabort rather than invoking yyFail, which invokes longjmp. Remove the
- now unnecessary yystackp parameter.
- (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
- destructors can be called.
-
- * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
- in existing testcases.
-
-2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Don't leak semantic values for parent RHS when a user action cuts the
- parser, and clean up related code a bit.
- * tests/glr-regression.at (Leaked merged semantic value if user action
- cuts parse): Rename to...
- (Leaked semantic values if user action cuts parse): ... this. Add check
- for leaked parent RHS values.
- * data/glr.c (yydestroyGLRState): In debugging output, distinguish
- between an unresolved state (non-empty chain of semantic options) and
- an incomplete one (signaled by an empty chain).
- (yyresolveStates): Document the interface. Move all manipulation of a
- successfully or unsuccessfully resolved yyGLRState to...
- (yyresolveValue): ... here so that yyresolveValue always leaves a
- yyGLRState with consistent data and thus is easier to understand.
- Remove the yyvalp and yylocp parameters since they are always just
- taken from the yys parameter. When reporting a discarded merged value
- in debugging output, note that it is incompletely merged. Document the
- interface.
- (yyresolveAction): If resolving any of the RHS states fails, destroy
- them all rather than leaking them. Thus, as long as user actions are
- written to clean up the RHS correctly, yyresolveAction always cleans up
- the RHS of a semantic option. Document the interface.

-
- Work around portability problems summarized by Nelson H. F. Beebe in
- <http://lists.gnu.org/archive/html/bug-bison/2005-09/msg00021.html>.
-
- * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
- that '#include <string>' works.
-
- * data/lalr1.cc (yytranslate_): No longer inline, to work around a
- porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
- "warning: sorry: semantics of inline function static data `const
- unsigned char translate_table[262]' are wrong (you'll wind up with
- multiple copies)".
-
- * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
- or, xor to not_, and_, or_, and xor_, respectively. This works
- around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
- random system header somewhere that includes the equivalent of
- <iso646.h>.

-
- During deterministic GLR operation, user actions should be able to
- influence the parse by changing yychar. To make this easier to fix and
- to make glr.c easier to evolve in general, don't maintain yytoken in
- parallel with yychar; just compute yytoken when needed.
- * tests/glr-regression.at (Incorrect lookahead during deterministic
- GLR): Check that setting yychar in a user action has the intended
- effect.
- * data/glr.c (yyGLRStack): Remove yytokenp member.
- (yyclearin): Don't set *yytokenp.
- (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
- yychar rather than *yytokenp to determine the current lookahead.
- Compute yytoken locally when needed.
- (yyparse): Likewise. Remove the local yytoken that yytokenp used to
- point to.

- normal case.
-
- Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
- got from <http://bro-ids.org/download.html>. The bug is that
- when two actions appeared in succession, the second one was
- scanned before the first one was added to the grammar rule
- as a midrule action. Bison then output the incorrect warning
- "parse.y:905.17-906.36: warning: unused value: $3".
- * src/parse-gram.y (BRACED_CODE, action): These are no longer
- associated with a value.

- (action): Invoke it here instead.
- * src/reader.c (grammar_midrule_action): Now extern.
- (grammar_current_rule_action_append): Don't invoke
- grammar_midrule_action; that is now the scanner's job.

- (grammar_midrule_action): New decls.
- * src/scan-gram.l (last_string): Now extern, sigh.
- (last_braced_code_loc): New extern variable.
- (<INITIAL>"{"): Invoke grammar_midrule_action if the current
- rule already has an action.
- (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
- * tests/input.at (AT_CHECK_UNUSED_VALUES):
- Add some tests to check that the above changes fixed the bug.
-
-2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
-
- * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
- All used changed. Check whether the symbol has a destructor,
- not whether it is typed.
- * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
- that the values are still reported as unused. All line numbers
- adjusted.

-
- * src/reader.c (check_and_convert_grammar): New function.
- (reader): Close the input file even if something went wrong during

-
- * src/assoc.c (assoc_to_string): Use a default: abort (); case
- to pacify gcc -Wswitch-default.
- * src/scan-gram.l (adjust_location): Use a default: break; case
- to pacify gcc -Wswitch-default.
- * src/scan-skel.h (skel_get_lineno, skel_get_in, skel_get_out):

- visible elsewhere.
- * src/scan-skel.l: Accept the above decls.
- (skel_lex): New decl, to pacify GCC when unpatched flex 2.5.31
- is used.

-
- * data/glr.c (yyresolveValue): When merging semantic options, if at
- least one user action succeeds but a later one cuts the parse, then
- destroy the semantic value before returning rather than leaking it.
- (yyresolveStates): If a user action cuts the parse and thus
- yyresolveValue fails, ignore the (unset) semantic value rather than
- corrupting the yyGLRState, and empty the semantic options list since
- the user actions should have called all necessary destructors.
- Simplify code with YYCHK.
- * tests/glr-regression.at (Corrupted semantic options if user action
- cuts parse): New test case.
- (Undesirable destructors if user action cuts parse): New test case.

- Use unlocked I/O for a minor performance improvement on hosts like
- GNU/Linux and Solaris that support unlocked I/O. The basic idea
- is to use the gnlib unlocked-io module, and to prefer putc and

- come in an unlocked flavor).

- "make check" doesn't finish with "All 1 tests passed".
-
- * tests/regression.at (Token definitions): Don't rely on
- AT_PARSER_CHECK for data that contains backslashes. It currently
- uses 'echo', and 'echo' isn't portable if its argument contains
- backslashes. Problem found on OpenBSD 3.4. Also, do not assume
- that the byte '\0xff' is not printable in the C locale; it is,
- under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
- not printable, so use '\0x81' to test.
-
- * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
- version of GCC, since the macro is used with non-GCC compilers.

- that we're the same as coreutils.
- (alpha, beta, major): Depend on news-date-check.
- Make the upload commands.

-
-2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
-
- * configure.ac: Update version number.
-
- * Makefile.am (SUBDIRS): Add examples; somehow this got removed

- from maintainer-distcheck about casting the argument of 'free'.
-
- * NEWS: Mention recent yytname changes.
- * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
-
- * bootstrap: For translations that have not yet been upgraded to
- the new runtime-po domain, prime the pump by extracting the
- relevant strings from the obsolete translations. This code can be
- removed once the bison-runtime domain has been translated by each
- team.
-
- * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
- now that token names are already quoted.
-
- Fix problem reported by Anthony Heading.

-
- * data/glr.c (yytnamerr): New function.
- (yyreportSyntaxError): Use it to dequote most string literals.

- (yyerrlab): Use it to decode most string literals.
- * doc/bison.texinfo (Decl Summary, Calling Convention):
- Clarify quoting convention of yytname.

- changes in the parsers as described above.
- * tests/regression.at (Token definitions, Web2c Actions):
- Undo most 2005-04-17 change here, too.
-
-2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
-
- Fix more problems reported by twlevo@xs4all.nl.
- * tests/cxx-type.at: Don't pipe output of ./types through sed to
- remove trailing spaces. This loses the exit status of ./types,
- and isn't needed since ./types shouldn't be emitting trailing
- spaces.
- * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
- as the stack isn't valid in that case.
-
- * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
- (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
- (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
- Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
- is used.
- * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
- (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
- (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
- Likewise.
-
- * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
- overly-picky compilers that reject 'char *foo = "bar";'.
-
- * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
- to FILE * parameter, not to stderr. This fixes a typo introduced
- in the 2005-07-12 change.
-
- * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
- warnings from GCC 4.
-
- * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):

-2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
-
- Destructor cleanups and regularization among the three skeletons.
- * NEWS: Document the behavior changes.
- * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
- stack before failing, as the cleanup code will do it for us now.
- * data/lalr1.cc (yyerrlab): Likewise.
- * data/glr.c (yyparse): Pop everything off the stack before
- freeing it, so that destructors get called properly.
- * data/lalr1.cc (yyreturn): Likewise.
- * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
- This is more consistent.
- * doc/bison.texinfo (Destructor Decl): Mention more reasons
- why destructors might be called. 1.875 -> 2.1.
- (Destructor Decl, Decl Summary, Table of Symbols):
- Some English-language cleanups for %destructor.
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
- Add output line for destructor of start symbol.
- * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
- because of that same extra output line.
-
- * NEWS: Document minor wording changes in diagnostics of
- Bison-generated parsers.
- * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
- Remove unused formals. All uses changed.
- (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
- (yyparse): Rename yyoverflowlab to yyexhaustedlab.
- * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
- Rename yyoverflowab to yyexhaustedlab.
- When memory exhaustion occurs during syntax-error reporting,
- report it separately rather than in a single diagnostic; this
- eases translation.
- * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
- (Memory Exhausted): Renamed from Parser Stack Overflow.
- Revamp wording slightly to prefer "memory exhaustion".
- * tests/actions.at: "parser stack overflow" -> "memory exhausted".
-
- * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
-
- Add i18n support to the GLR skeleton. Partially fix the C++
- skeleton; a C++ expert needs to finish this. Remove debugging
- msgids; there's little point to having them translated, since they
- can be understood only by someone who can read the
- (English-language) source code.
-
- Generate runtime-po/bison-runtime.pot automatically, so that we
- don't have to worry about garbage getting in that file. We'll
- make sure after the next official release that old msgids don't
- get lost. See
- <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
-
- * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
- Now auto-generated.
- * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
- Fix typos in explanations of the runtime file.
- * bootstrap: Change gettext keyword from YYI18N to YY_.
- Use standard Makefile.in.in in runtime-po, since we'll arrange
- for backward-compatible bison-runtime.po files in a different way.
- * data/glr.c (YY_): New macro, from yacc.c.
- (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
- Translate messages intended for users.
- (yyreportSyntaxError): Change "virtual memory" to "memory" to match
- the wording in the other skeletons. We don't know that the memory
- is virtual.
- * data/lalr1.cc (YY_): Renamed from _. All uses changed.
- Use same method that yacc.c uses.
- Don't translate debugging messages.
- (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
- it doesn't work (yet), and requires C++ expertise to fix.
- * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
- Move defn to a more logical place, to be consistent with other
- skeletons.
- Don't translate debugging messages.
- Don't assume line numbers fit in unsigned int; use unsigned long fmts.
- * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
- to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
- * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
-
- Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
- * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
- void, not int.
- * tests/glr-regression.at (Badly Collapsed GLR States):
- Likewise.
- (Improper handling of embedded actions and dollar(-N) in GLR parsers):
- yylex should return 0 at EOF rather than aborting.
-
- Improve tests for stack overflow in GLR parser.
- Problem reported by twlevo@xs4all.nl.
- * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
- All uses removed.
- (yyStackOverflow): Just longjmp, but with value 2 so that caller
- can handle the problem.
- (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
- (yyparse): New local variable yyresult to record the result.
- Use result of setjmp to set it, rather than storing itinto
- struct.
- (yyDone): Remove label.
- (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
- to mimic yacc.c. Do not discard lookahead if it's EOF (possible
- if YYABORT is used).
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
- yyparse status; put status > 1 into diagnostic.
- Check that status==2 works.
- * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
- Use exit status 3 for failure to open (which shouldn't happen).
-
-2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
-
- * tests/conflicts.at (%nonassoc and eof): Don't exit with status
- 1 on syntax error; just let yyparse do its thing.
- * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
- * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
- (Exploding the Stack Size with Alloca):
- (Exploding the Stack Size with Malloc):
- Expect exit status 2, not 1, since the parser is supposed to blow
- its stack. Problem reported by twlevo@xs4all.nl.
-
- * data/glr.c (yyparse): Don't assume that the initial calls
- to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
- Print a stack-overflow message and fail instead.
- Initialize the line-number information before creating the stack,
- so that the stack-overflow message can report line zero safely.
-
-2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
-
- Fix problems reported by twlevo@xs4all.nl.
- * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.

- (Improper handling of embedded actions and dollar(-N) in GLR parsers):
- Add casts to pacify C++ compilers.
- * tests/glr-regression.at (Improper merging of GLR delayed action
- sets): Declare yylex before using it.
- * tests/Makefile.am (maintainer-check-g++): Fix a stray
- $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
- test for valgrind; valgrind is independent of g++.
- (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
- for compatibility with POSIX 1003.1-2001 (if running coreutils).
- * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
- Use a destructor, so that we can expand the stack. Change
- YYSTYPE to char * so that we can free it. Cast result of malloc.
-
-2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
-
- * data/glr.c (yyuserAction): Fix uninitialized variable that caused

-
- * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:

- Put comment before action, since older 'make' can't handle comment
- in action.
- $(BUILT_SOURCES): List all built sources, not just some of them.
- $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
- $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.

-2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/glr.c (yyFail): Drastically simplify; since the format argument
- never had any % directives, we can simply pass it to yyerror.
- (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
- be modified later, as that is the usual style in glr.c.
- Problems reported by Paul Hilfinger.
-
- Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
- and size overflow errors.
- * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
- in case the user prolog sets feature-test macros like _GNU_SOURCE.
- (YYSIZEMAX): New macro.
- (yystpcpy): New function, taken from yacc.c.
- (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
- (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
- so that we don't have to maintain their signatures.
- (yyFail): Check for buffer overflow, by using vsnprintf rather
- than vsprintf. Allocate a bigger buffer if possible.
- Report an error if buffer allocation fails.
- (yyStackOverflow): New function.
- (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
- the initialization was successful. It might fail if storage was
- exhausted.
- (yyexpandGLRStack): Add more checks for storage allocation failure.

- Don't assume stack number fits in int.
- (yysplitStack): Check for storage allocation failure.

- Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
- the user's name space.
- (alloca): Include <stdlib.h> to get it, if it's not built in.
- (YYMALLOC, YYFREE): Define only if needed.
- (malloc, free): Declare, but only if needed, as this infringes on
- the user name space.

-2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
-
- * NEWS: Version 2.0a.

- the previous change.
-
- Various maintainer cleanups.
- * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
- conftest*, for benefit of CVS commands run at the same time as

- (yyoverflowlab): Don't call destructor.
- (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
- * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,

- From Marcus Holland-Moritz.
- * data/yacc.c (yyerrlab): Move the code that destroys the stack
- from here....
- (yyreturn): to here. That way, destructors are called properly
- even if the stack overflows, or the user calls YYACCEPT or
- YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
- (yyoverflowlab): Destroy the lookahead.
-
-2005-04-24 Paul Eggert <eggert@cs.ucla.edu>

-
- * NEWS: Bison-generated C parsers no longer quote literal strings

- in diagnostics.
- * tests/input.at (Torturing the Scanner): Likewise.
- * tests/regression.at (Token definitions, Web2c Actions): Likewise.
-
-2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
-
- * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
- the data size is known to be too small and we can't increase it.
- This works around an HP-UX 11.00 glitch reported by Andrew Benham.
-
-2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
-
- * src/parse-gram.y: Include quotearg.h.
- (string_as_id): Quote $1 before using it as a key, since the
- lexer no longer quotes it for us.

- quotes it for us.
- * src/scan-gram.l: Include quotearg.h.
- ("\""): Omit quote.
- ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
- a key, since the rest of the lexer doesn't quote it.
- * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
- * tests/regression.at (Token definitions): Check for backslashes
- in token strings.
-
- * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
- (YYSIZE_T): Define to unsigned long int when using an older compiler.
- (yyparse): Revamp code to generate long syntax error message, to
- make it easier to translate, and to avoid problems with arithmetic
- overflow. Change "virtual memory" to "memory" in diagnostic, since
- we don't know whether the memory is virtual.
-
-2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
-
- * NEWS: Bison-generated C parsers now use the _ macro to
- translate strings.
- * data/yacc.c (_) [!defined _]: New macro.
- All English strings wrapped inside this macro.
- * doc/bison.texinfo (Bison Parser): Document _.
- * po/POTFILES.in: Include src/parse-gram.c, since it now
- includes translateable strings that parse-gram.y doesn't.
-
-2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
-
- * src/symtab.c (symbol_make_alias): Call symbol_type_set,
- reverting the 2004-10-11 change to this function.
- (symbol_check_alias_consistency): Don't call symbol_type_set
- if the type name is already correct.
- * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
-
-2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
-
- * tests/regression.at (Token definitions): Don't use a token named
- c, as that generates a "#define c ..." that runs afoul of buggy
- stdlib.h that uses the identifier c as a member of struct
- drand48_data. Problem reported by Horst Wente.
-
-2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
-
- * bootstrap: Change translation URL from
- http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to

-2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
-
- * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options

-
-2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
-
- * tests/glr-regression.at (glr-regr2a.y): Try to dump core

-
-2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
-
- * src/output.c (escaped_output): Renamed from
- escaped_file_name_output, since we now use it for symbol tags as
- well. All uses changed.
- (symbol_destructors_output, symbol_printers_output):
- Escape symbol tags too.
- Problem reported by Matyas Forstner in

-
-2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
-
- * NEWS: Version 2.0. Reformat the existing news items since
- 1.875, so that related items are grouped together.
- * configure.ac (AC_INIT): Bump version to 2.0.
- * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
-
- * tests/torture.at (Exploding the Stack Size with Alloca): Set
- YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
- otherwise, we're not testing alloca. Unfortunately there's no
- simple way to consult HAVE_ALLOCA here.
-
- * data/lalr1.cc (yydestruct_): Pacify unused variable warning
- for yymsg, too.
-
- * src/LR0.c (new_itemsets): Use memset rather than zeroing by
- hand. This avoids a warning about comparing int to size_t when
- GCC warnings are enabled.
-
-2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
-
- * NEWS: Bison-generated parsers no longer default to using the
- alloca function (when available) to extend the parser stack, due
- to widespread problems in unchecked stack-overflow detection.
- * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
- responsibility to set it to a positive value. This lets the user
- specify a value that is not a preprocessor constant.
- * data/yacc.c (YYMAXDEPTH): Likewise.
- (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
- * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
- to be a compile-time constant. However, explain the constraints on it.
- Also, explain the constraints on YYINITDEPTH.
- (Table of Symbols): Explain that alloca is no longer the default.
- Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
- to 1.
-
- * doc/bison.texinfo (Location Default Action): Mention that n must
- be zero when k is zero. Suggested by Frank Heckenbach.
-
-2004-12-22 Akim Demaille <akim@epita.fr>
-
- * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
- (parser::state_type, parser::semantic_type, parser::location_type):
- Private, not public.
- (parser::parse): Return ints, not bool.
- Returning a bool introduces a problem: 0 corresponds to false, and
- it seems weird to return false on success. Returning true changes
- the conventions for yyparse.
- Alternatively we could return void and send an exception.
- There is no clear consensus (yet?).
- (state_stack, semantic_stack, location_stack): Rename as...
- (state_stack_type, semantic_stack_type, location_stack_type): these.
- Private, not public.
- * tests/c++.at: New.
- * tests/testsuite.at, tests/Makefile.am: Adjust.
-
-2004-12-21 Akim Demaille <akim@epita.fr>
-
- * data/lalr1.cc (parser::parse): Return a bool instead of an int.
-
-2004-12-21 Akim Demaille <akim@epita.fr>
-
- Don't impose std::string for filenames.
-
- * data/lalr1.cc (b4_filename_type): New.
- (position::filename): Use it.
- (parser.hh): Move the inclusion of stack.hh and location.hh below
- the user code, so that needed headers for the filename type can be
- included first.
- Forward declare them before the user code.
- * tests/Makefile.am (check-local, installcheck-local): Pass
- TESTSUITEFLAGS to the TESTSUITE.
-
-2004-12-20 Akim Demaille <akim@epita.fr>
-
- Use more STL like names: my_class instead of MyClass.
-
- * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
- (SemanticStack, SemanticType, StateStack, StateType)
- (TokenNumberType, Stack, Slice, Traits, Parser::location)
- (Parser::value): Rename as...
- (location_stack, location_type, rhs_number_type, semantic_stack)
- (semantic_type, state_stack, state_type, token_number_type, stack)
- (slice, traits, parser::yylloc, parser::yylval): these.
-
- * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
-
-2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
- * data/yacc.c (YYLLOC_DEFAULT): Likewise.
-
-2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
-
- Remove uses of 'short int' and 'unsigned short int'. This raises
- some arbitrary limits. It uses more memory but nowadays that's
- not much of an issue.
-
- This change does not affect the generated parsers; that's a different
- task, as some users will want to conserve memory there.
-
- Ideally we should use size_t to represent all object counts, and
- something like ptrdiff_t to represent signed differences of object
- counts; but that will require more code-cleanup than I have the
- time to do right now.
-
- * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):

- * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit

-
-2004-10-05 Akim Demaille <akim@epita.fr>
-
- In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
- whether the reducion was empty or not. This leaves room to
- improve the use of YYLLOC_DEFAULT in such a case.
- lalr1.cc is still experimental, so changing this is acceptable.
- And finally, there are probably not many users who changed the
- handling of locations in GLR, so changing is admissible too.
-
- * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
- empty reduction, set @$ to an empty location ending the previously
- stacked symbol.
- Adjust uses to make sure the code is triggered on empty
- reductions.
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
- expected output: empty reductions have empty locations.

-
-2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
-
- * src/parse-gram.y (add_param): Rewrite to avoid strchr,

- the useless parentheses.
- Suggested by Paul Eggert.
-
-2004-09-20 Akim Demaille <akim@epita.fr>
-
- Let the initial-action act on the look-ahead, and use it for the
- "initial push" (corresponding to an hypothetical beginning-of-file).
- And let lalr1.cc honor %initial-action.
-
- * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
- example.
- * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
- (Parser::Parser): Remove the ctor that used to initialize it.
- (Parser::parse): Like in the other skeletons, issue the "starting
- parse" message before any action.

- (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
- When reducing on an empty RHS, use the latest stacked location as
- location.
- yylloc is not always available.
- * data/glr.c: Likewise.
- Also, honor initial-actions.
-
-2004-09-20 Akim Demaille <akim@epita.fr>
-
- * data/yacc.c (YY_LOCATION_PRINT): New.
- Define when we know YYLTYPE's structure, i.e., when the default
- YYLLOC_DEFAULT is used.
- * data/c.m4 (b4_yysymprint_generate): Use it.
- * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
- value of the result.
- (error_start_): Replace with...
- (error_range_): this location array.
- This allows to replace code relying on the implementation of
- locations by portable code.
- * data/yacc.c (yylerrsp): Replace with...
- (yyerror_range): this.
- Every time a token is popped, update yyerror_range[0], to have an

-
- * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
- (iterator, const_iterator): these, to be more in the C++ spirit.
- Also, return reverse iterators so that when displaying the stack
- we display its bottom first.
- (Parser::stack_print_, Parser::reduce_print_): Match the messages
- from yacc.c.
- We should probably use vector here though.
-
-2004-09-16 Akim Demaille <akim@epita.fr>
-
- Have more complete shift traces.
-
- * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
- to report Shifts instead of ad hoc YYDPRINTF invocations,
- including for the error token.
- * data/lalr1.cc (symprint_): Output the location.
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
- output the location within the %printer.
- Activate GLR tests, at least to make sure they compile properly.
- They still don't pass though.
- * tests/calc.at: Adjust expect verbose output, since now "Entering
- state..." is on a different line than the "Shifting" message.

- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
- Bison directive from the Bison file to the invocation of this
- macro, so that these directives are passed to
- AT_BISON_OPTION_PUSHDEFS to get correct help macros.
- Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
- Move the AT_SETUP/AT_CLEANUP outside, to report as test title
- the extra Bison directives instead of the whole series.
- Change the grammar so that there are recoverable errors, and
- unrecoverable errors. Now we can have the parser give up before
- consuming the whole input. As a result we now can observe that
- the lookahead is freed when needed.
- Change the parser source to parse argv[1] instead of a hard coded
- string.
- Simplify yylex, and give a value and location to EOF.
- Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
- passed directives already coded in the file.
- Add some tests to check the location of "error".
- For some tests, the C++ parser is correct, and not yacc.c.
- For other tests, they provide different, but unsatisfying, values,
- so keep the C++ value so that at least one parser is "correct"
- according to the test suite.
- (Actions after errors): Remove, this is subsumed by the
- AT_CHECK_PRINTER_AND_DESTRUCTOR series.
-
-2004-09-06 Akim Demaille <akim@epita.fr>

- argument, an informative message.
- Call YY_SYMBOL_PRINT.
- Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
- * data/lalr1.cc (destruct_): Likewise.
- In addition, no longer depend on b4_yysymprint_generate and
- b4_yydestruct_generate to generate these functions, do it "by
- hand".
-
-2004-09-03 Akim Demaille <akim@epita.fr>
-
- * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
- invoked, yydestruct the lookahead.

- one.
-
-2004-09-02 Akim Demaille <akim@epita.fr>
-
- * data/lalr1.cc (b4_yysymprint_generate): New.
- (symprint_): New member function, defined when YYDEBUG.
- Use it consistently instead of token/nterm debugging output by
- hand.
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
- %printer calls to use cdebug_ when using lalr1.cc.
-
-2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
-
- * data/glr.c: Guard the declarations of yypstack and yypdumpstack
- with #ifdef YYDEBUG.
-
-2004-08-26 Akim Demaille <akim@epita.fr>
-
- * doc/bison.texinfo (Implementing Loops): Rename as...
- (Implementing Gotos/Loops): this.
-
-2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
-
- Adjust to latest gnulib.
- * bootstrap (gnulib_modules): Add xalloc-die.
- Set LC_ALL=C so that file names sort consistently.
- Prefer the gnulib copies of gettext.m4, glibc21.m4,
- inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
- uintmax_t.m4, ulonglong.m4.
- (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
- po.m4 since we are now using _gl.m4 instead.
-
-2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
-
- * src/scan-action.l: Remove. Scanning of semantic actions is
- handled in scan-gram.l.
-
-2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
-
- * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
-
- * src/location.h (struct): The file member is a uniqstr.
- (equal_boundaries): Use UNIQSTR_EQ for comparison.

-
- Fix bug with non-%union parsers that have printers or destructors,
- which led to a Bison core dump. Reported by Peter Fales in
- <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
-

- UNION-FLAG. All callers changed.
- (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
- Use type char, not unsigned int, when declaring an array of char;

-
-2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
-
- * doc/bison.texinfo: Minor editorial changes, mostly to the new

- C++ compiler. (trivial change)
-
-2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
-
- Spent a few hours checking out which prerequisite versions the
- current sources actually require. I went all the way back to
- Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
- a seemingly endless set of combinations of versions more recent
- than that. The bottom line is that the current sources require
- fairly recent versions of the build tools, and it'll be some work
- to change this.
- * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
- (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
- (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
- Add comments explaining why those particular versions are
- currently needed.
-
- * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
- in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
- <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
-
- * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
- (it fails with a Autoconf-without-aclocal-m4 diagnostic).
-
-2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
-
- * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
- 0.11.5. Suggested by Bruno Haible.
- * bootstrap: Remove gettext version checking.
-
- * doc/bison.texinfo (Decl Summary): Also mention that %union
- can depend on prerequisite types. Problem reported by Tim
- Van Holder.
-
-2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
-
- * README: Mention GNU m4 1.4 bugs and Akim's patched version.

- gettext better.
-
- * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
- put into the -d output file, and mention what to do if YYSTYPE is
- defined as a macro.
-
-2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
-
- Undo change made earlier today: it caused autopoint to not bring
- in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
- autopoint's.
-
- * bootstrap: Check that gettext version matches what's in
- configure.ac. Warn users to ignore robots.txt ERROR 404.
- * bootstrap: Undo today's earlier change (logged below).
- * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
-
- The gettext version checking is causing more trouble than it's
- curing; remove it. Problem reported by Paul Hilfinger.
-
- * bootstrap: Issue a warning that one can expect a message
- 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
- * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
-
-2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
-
- Ensure that the C++ compiler used for testing actually works on a

-
- * configure.ac (AC_INIT): Update to 1.875e.

- supported by GCC 3.4.0.
- * README: Mention GNU m4 1.4 or later; mention m4 patches.
- * HACKING: Use ./bootstrap, not "make update" to import foreign files.
-
-2004-05-06 Paul Eggert <eggert@cs.ucla.edu>

- * src/parse-gram.y: Put copyright notice inside %{ %} so it
- gets copied to the output file.
-
-2004-04-28 Paul Eggert <eggert@twinsun.com>
-
- Get files from the gnulib and po repositories, instead of relying
- on them being in our CVS. Upgrade to latest versions of gnulib
- and Automake.
-
- * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
- * bootstrap: Bootstrap from gnulib and po repositories.
- Much of this code was stolen from GNU diff and GNU tar's bootstrap.
- * README-cvs: Document these changes. Remove version numbers from
- mentions of build tools, since they change so often. Mention Flex.
-
- * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
- (gl_USE_SYSTEM_EXTENSIONS): Add.
- (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
- Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
- does this for us.

- ancient OS, as it gets in the way of latest Autoconf & gnulib.
- (AC_HEADER_STDC): Remove: we now assume C89 or better.

- Do not check for C89 headers, except for locale.h which is used
- by the Yacc library and must port to K&R hosts.
- (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
- Do not check for C89 functions, except for setlocale which is
- used by the Yacc library.

- for us.
-
- * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
- (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
- Define to empty, as gnulib.mk will do the rest for us.
- ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
- for us.
- (libbison_a_SOURCES): Define to $(lib_SOURCES) now.

-
- * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
- case, as stos_ is now used by destructors due to the 2004-02-09
- change.

- * lib/bitset.h (__INT_TO_PTR): Remove; workaround no longer needed
- with latest obstack.h.
- * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args

-
- * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
- so that this include file can stand alone.

- does this now. Include subpipe.h first after config.h, to
- test whether it can stand alone.
-
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
- declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the

- When reducing initial empty rules, Bison parser read an initial
- location that is not defined. This results in garbage, and that
- affects Bison's own parser. Therefore we need (i) to extend Bison
- to support a means to initialize this location, and (ii) to use
- this CVS Bison to fix CVS Bison's parser.

- lalr1.cc and yacc.c.
- (YYERROR): Goto to yyerrorlab, not yyerrlab1.

- yyerrlab), when hitting EOF, pop the whole stack here instead of
- merely falling thru the default error handling mechanism.
- (yyerrorlab): New label, with the old contents of YYERROR,

- fail.
-
-2003-08-25 Akim Demaille <akim@epita.fr>

- to g++, as GCC 3.3 complains if you do it.
- * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
- everything that WARNING_CFLAGS has, except omit warnings
- not suitable for C++.
- (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
- * tests/atlocal.in (CXXFLAGS): New var.
- * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
-
- Fix a GLR parser bug I reported in February; see
- <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
- The problem was that GLR parsers did not conform to the C standard,
- because actions like { $1 = $2 + $3; } expanded to expressions
- that invoked YYFILL in separate subexpressions, and YYFILL assigned
- to a local variable. The C standard says that expressions
- like (var = f ()) + (var = f ()) have undefined behavior.
- Another problem was that GCC sometimes issues warnings that
- yyfill and its parameters are unused.
-
- * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
- as possibly unused.
- (yyfill): New function.
- (YYFILL): Use it.
- (yyuserAction): Change type of yynormal to bool, so that it matches
- the new yyfill signature. Mark it as possibly unused.
-
-
- Follow up on a bug I reported in February, where a Bison-generated
- parser can loop. Provide a test case and a fix for yacc.c. I
- don't have a fix for lalr1.cc or for glr.c, unfortunately.
- The original bug report is in:
- <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
-
- * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
- macro's size was becoming unwieldy.
- (yyerrlab): Do not discard an empty lookahead symbol, as this
- might destroy garbage.
- (yyerrorlab): New label, with the old contents of YYERROR,
- plus the following change: pop the stack of rhs corresponding
- to the production that invoked YYERROR. That is how Yacc
- behaves, and POSIX requires this behavior.
- (yyerrlab1): Use YYPOPSTACK instead of its definiens.
- * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
- Define 'alarm' to do nothing if unistd.h is not available.
- Add a new rule "exp: '-' error;" to test the above change to
- data/yacc.c. Use 'alarm' to abort any test taking longer than
- 10 seconds, as it's probably looping.
- (AT_CHECK_CALC): Test recovery from error in new grammar rule.
- Also, the new yacc.c generates two fewer diagnostics for an
- existing test.
-
-2003-05-24 Paul Eggert <eggert@twinsun.com>
-
- * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
- YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.

-2003-05-14 Paul Eggert <eggert@twinsun.com>
-
- * src/parse-gram.y (rules_or_grammar_declaration): Require a
- semicolon after a grammar declaration, in the interest of possible
- future changes to the Bison input language.
- Do not allow a stray semicolon at the start of the grammar.
- (rhses.1): Allow one or more semicolons after any rule, including

-
-2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
-

- b4_cc_constructor_calls, b4_cc_constructor_call,
- b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
- definitions.
- (yy::b4_parser_class_name::b4_parser_class_name): Take extra
- parse-param arguments.
- (yy::b4_parser_class_name): Declare instance variables to
- hold parse-param arguments.
- * tests/calc.at: s/value/semantic_value/ because value clashes
- with a member of yy::b4_parser_class_name. Adjust C++ code
- to handle %parse-param. Enable %parse-param test in C++.
-
-2003-05-12 Paul Eggert <eggert@twinsun.com>
-
- * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
- English a bit. Fix fclose typo. Change "const char" to "char
- const", and use ANSI C rather than K&R for "main". Suggest
- YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
- and suggest yy_switch_to_buffer.
-
-2003-05-05 Paul Eggert <eggert@twinsun.com>
-
- * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
- C89. This avoids a diagnostic on compilers that define __STDC__
- to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
- <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
-

-
-2003-04-29 Akim Demaille <akim@epita.fr>
-
- * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
- * src/getargs.c, src/getargs.h: here, as bool, not int.
- (nondeterministic_parser): New.
- * src/parse-gram.y, src/scan-gram.l: Support
- %nondeterministic-parser.
- * src/output.c (prepare): Use nondeterministic_parser instead

-
-2003-04-29 Akim Demaille <akim@epita.fr>

- with %pure-parser and %locations to exercise the patch from Yakov
- Markovitch below.
-
-2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
-
- * data/yacc.c: (b4_lex_param): Corrected for the case where

-
-2003-04-27 Paul Eggert <eggert@twinsun.com>
-
- Avoid gcc -Wundef warnings reported by Gerald Pfeifer in

- if it is not defined.
- (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
-
-2003-04-26 Paul Eggert <eggert@twinsun.com>
-
- * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
- Declare to be of type suitable for the ninf value itself, not of
- type suitable for the corresponding table, since the latter might
- be unsigned but the ninf value might be negative. This fixes a
- bug reported by Alexandre Duret-Lutz in
- <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
-
- * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
- invokes it. We shouldn't invoke it twice because it will attempt
- to put error.o in the archive twice. This fixes a glitch reported
- by Martin Mokrejs in
- <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
-
-2003-04-21 Paul Eggert <eggert@twinsun.com>

-
- * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
- Fix obvious typo that results in uncompilable GLR parsers
- when both %pure-parser and %locations are used. (trivial change)
-
-2003-04-17 Paul Eggert <eggert@twinsun.com>
-
- * src/scan-gram.l: Add %option nounput, since we no longer use unput.
- (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
- Do not insert the expected token via unput, as this runs afoul
- of a POSIX-compatibility bug in flex 2.5.31.
- All uses changed to BEGIN the parent state,
- since we no longer insert the expected token via unput.
- * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
- that is no longer emitted after the above change.
-
- * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
- the first one. This change is from Paul Hilfinger, and it fixes
- regression reported by Werner Lemberg in
- <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
-
- (resolve_sr_conflict): Don't invoke state_errs_set
- unless one or more tokens have been explicitly made errors.
- Otherwise, the above change causes Bison to abort.
-
- * tests/existing.at (GNU pic Grammar): New test case, taken from
- Lemberg's email.

-
- * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
- (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
- cursor, instead of leaving it undefined. This fixes a bug
- reported by Tim Van Holder in
- <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
- * tests/input.at (Torturing the Scanner): Test the scanner on
- an empty input file, which was Tim Van Holder's test case.
-
- * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
- <sys/resource.h> can be included, include sys/time.h and
- sys/times.h first, if available. This works around the SunOS
- 4.1.4 porting bug reported by Bruce Becker in
- <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
-
- * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
- AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
- AC_HEADER_SYS_WAIT.
-
- Merge changes from gnulib. This was prompted because the CVS
- snapshot didn't build on Solaris 7 due to strnlen problems.
-
- These changes need to be merged back into gnulib:
- * lib/hash.c: Include <stdbool.h> unconditionally.
- * m4/onceonly.m4 (m4_quote): New macro.
- (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):

-
-2003-03-02 Akim Demaille <akim@epita.fr>
-
- * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
- generate verbose error messages.

- Ignore the test if CXX is not functional.
-
-2003-03-01 Paul Eggert <eggert@twinsun.com>
-
- * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
- not loc->end, since loc->end might contain garbage and this leads
- to undefined behavior on some platforms.
- (id_loc, token_start): Use (IF_LINTed) initial values that do not
- depend on *loc, so that the reader doesn't give the the false
- impression that *loc is initialized.
- (<INITIAL>"%%"): Do not bother setting code_start, since its value
- does not survive the return.
-
-2003-03-01 Akim Demaille <akim@epita.fr>
-
- * src/scan-gram.l (code_start): Always initialize it when entering
- into yylex, as SC_EPILOGUE is activated *before* the corresponding
- yylex invocation. An alternative would be making it static, but
- then it starts with the second %%'s beginning, instead of its end.
-
-2003-02-28 Paul Eggert <eggert@twinsun.com>
-
- * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
- around a UnixWare 7.1.1 porting bug reported by John Hughes in

-
- * README: Mention compiler bug in Sun Forte Developer 6 update 2.

- Merge VMS and MS-DOS discussion; these ports may well be dead
- but let's keep mentioning them for now. Put <> around email
- addresses. Add copyright notice.

-
-2003-02-21 Akim Demaille <akim@epita.fr>
-
- * doc/bison.texinfo: Use "location" consistently to refer to @n,

- Suggested by Paul Eggert.
-
-2003-02-20 Akim Demaille <akim@epita.fr>
-
- * data/lalr1.cc (position.hh): Make sure "columns" never pushes
- before initial_columns.
- (location.hh): Use consistent variable names when defining the
- operator<<.
- Use "last" so that we subtract from Positions, not from unsigned.
-
-2003-02-20 Akim Demaille <akim@epita.fr>
-
- * data/lalr1.cc (position.hh): New subfile, including the extended
- and Doxygen'ed documentation of class Position.

- Document a` la Doxygen.
- With the help of Benoit Perrot.
-
-2003-02-20 Akim Demaille <akim@epita.fr>

- * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
- AT_YACC_IF.
- Redefine AT_YYERROR_SEES_LOC_IF using it.
- (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
- not defined.
- Don't use the location in yy::Parser::error_ and
- yy::Parser::print_ when not %locations.
- Activate more lalr1.cc tests.
-
-2003-02-19 Akim Demaille <akim@epita.fr>

-
-2003-02-02 Akim Demaille <akim@epita.fr>
-
- * src/scan-skel.l: Scan more than one inert character per yylex
- invocation.

-
- * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
-
-2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
-
- * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
- of $1.
-
- Changes in response to error report by S. Eken: GLR mode does not
- handle negative $ indices or $ indices in embedded rules correctly.
- See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
-
- * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
- (b4_rhs_location): Ditto.
- (yyfill): New function to copy from stack tree into array
- incrementally.
- (yyuserAction): Modify to allow incremental move of semantic values
- to rhs array when in GLR mode.
- Define YYFILL to use in user-defined actions to fill semantic array
- as needed.
- Remove dummy use of yystack, as there is now a guaranteed use.
- (yydoAction): Modify to allow incremental move of semantic values
- to rhs array when in GLR mode.
- (yyresolveAction): Ditto.
- (yyglrShiftDefer): Update comment.

-2003-01-28 Paul Eggert <eggert@twinsun.com>
-
- * data/lalr1.cc: Do not use @output_header_name@ unless

- Tim Van Holder in
- <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
- and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
-
-2003-01-21 Paul Eggert <eggert@twinsun.com>
-
- * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
- we don't need to worry about yyerrlab1 being reported as an
- "unused label" by non-GCC C compilers. The downside is that if
- locations are used then a couple of statements are duplicated each
- time YYERROR is invoked, but the upside is that the warnings
- should vanish.
- (yyerrlab1): Move code to YERROR.
- (yyerrlab2): Remove. Change uses back to yyerrlab1.
- This reverts some of the 2002-12-27 change.
-
-2003-01-17 Paul Eggert <eggert@twinsun.com>
-
- * src/output.c (symbol_printers_output): Fix typo that led

- Quoc Peyrot <chojin@lrde.epita.fr>,
- Robert Anisko <anisko_r@lrde.epita.fr>
-
- * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
- when the stacks contain one element, as the loop would otherwise
- free the last state, and then use the top state (the one we just
- popped). This means that the initial elements will not be freed
- explicitly, as is the case in yacc.c; it is not a problem, as
- these elements have fake values.
-
-2003-01-11 Paul Eggert <eggert@twinsun.com>
-
- * NEWS: %expect-violations are now just warnings, reverting
- to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
- bootstrapping problem reported by Matthias Klose; see
- <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
- * src/conflicts.c (conflicts_print): Likewise.
- * tests/conflicts.at (%expect not enough, %expect too much,

- (not necessarily increases).
-
- * src/getargs.c (version): Update copyright year.
-
-2003-01-09 Akim Demaille <akim@epita.fr>
-

-
-2003-01-08 Paul Eggert <eggert@twinsun.com>
-
- * Makefile.maint (WGETFLAGS):
- New macro, containing "-C off" to disable proxy caches.
- All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
- (rel-check): Use $(WGET) instead of wget.
-
-2003-01-06 Paul Eggert <eggert@twinsun.com>
-

-
- * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
- (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
- * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.

- * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
- (EXTRA_SCRIPTS): New var, for yacc.
-
- * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
- since GNU C++ (as of 3.2.1) does not allow attributes on labels.
- Problem reported by Nelson H. F. Beebe.
-
-2003-01-03 Paul Eggert <eggert@twinsun.com>
-
- * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
- (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
- when compiling Bison 1.875's `bitset bset = obstack_alloc
- (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
-
- * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
- ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
- grow to a huge size with typical invocation.
-
- * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
- Use the pattern recommended by Autoconf 2.57, except also protect
- against double-definition.
- * src/system.h: Likewise.
- Portability issues reported by Nelson H. F. Beebe.
-
- * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
- All uses changed. Provide a definition in both C and C++.
- (yytrue, yyfalse): Define even if defined (__cplusplus).
-
- * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
- Reported by Nelson H. F. Beebe.

-
-2003-01-02 Paul Eggert <eggert@twinsun.com>

- pacify the buggy "smart preprocessor" in MacOS 10.2.3.
- Bug reported by Nelson H. F. Beebe.
-
-2003-01-01 Paul Eggert <eggert@twinsun.com>
-
- * Version 1.875.
-
-2002-12-30 Paul Eggert <eggert@twinsun.com>
-
- * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
- Moved here from...
- (<INITIAL>","): Here. This causes stray "," to be treated
- more uniformly.
-
- * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
- last brace in braced code when not in Yacc mode, for compatibility
- with Bison 1.35. This resurrects the 2001-12-15 patch to
- src/reader.c.
-
- * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
- yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
-
-2002-12-28 Paul Eggert <eggert@twinsun.com>
-
- * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
- that of SYM's type. This fixes Debian bug 168069, reported by
- Thomas Olsson.
-
-2002-12-28 Paul Eggert <eggert@twinsun.com>
-
- Version 1.75f.
-
- Switch back to the Yacc style of conflict reports, undoing some
- of the 2002-07-30 change.
- * doc/bison.texinfo (Understanding): Use Yacc style for
- conflict reports. Also, use new way of locating rules.
- * src/conflicts.c (conflict_report):
- Renamed from conflict_report_yacc, removing the old
- 'conflict_report'. Translate the entire conflict report at once,
- so that we don't assume that "," has the same interpretation in
- all languages.
- (conflicts_output): Use Yacc-style conflict report for each state,
- instead of our more-complicated style.
- (conflicts_print): Use Yacc-style conflict report, except print
- the input file name when not emulating Yacc.
- * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
- Conflicted Reduction, %expect not enough, %expect too much,
- %expect with reduce conflicts): Switch to Yacc-style conflict reports.
- * tests/existing.at (GNU Cim Grammar): Likewise.
- * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
-
- * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
- fatal): Don't invoke fflush; it's not needed and it might even be
- harmful for stdout, as stdout might not be open.
- * src/reduce.c (reduce_print): Likewise.
-
-2002-12-27 Paul Eggert <eggert@twinsun.com>
-
- Fix a bug where error locations were not being recorded correctly.
- This problem was originally reported by Paul Hilfinger in
- <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
-
- * data/yacc.c (yyparse): New local var yylerrsp, to record the
- top of the location stack's error locations.
- (yyerrlab): Set it. When discarding a token, push its location
- onto yylerrsp so that we don't lose track of the error's end.
- (yyerrlab1): Now is only the target of YYERROR, so that we can
- properly record the location of the action that failed. For GCC
- 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
- GCC warning about yyerrlab1 being unused if YYERROR is unused.
- (yyerrlab2): New label, which yyerrlab now falls through to.
- Compute the error's location by applying YYLLOC_DEFAULT to
- the locations of all the symbols that went into the error.
- * doc/bison.texinfo (Location Default Action): Mention that
- YYLLOC_DEFAULT is also invoked for syntax errors.
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
- Error locations include the locations of all the tokens that were
- discarded, not just the last token.
-
-2002-12-26 Paul Eggert <eggert@twinsun.com>
-
- * src/files.c: Include quote.h.
- (compute_output_file_names): Warn if we detect conflicting
- outputs to the same file. This should catch the misunderstanding
- exemplified by Debian Bug 165349, reported by Bruce Stephens..
-
- * src/conflicts.c (conflicts_print): If the user specifies
- "%expect N", report an error if there are any reduce/reduce
- conflicts. This is what the manual says should happen.
- This fixes Debian bug 130890, reported by Anthony DeRobertis.
- * tests/conflicts.at (%expect with reduce conflicts): New test.
-
- Don't use m4_include on relative file names, as it doesn't work as
- desired if there happens to be a file with that name under ".".
-
- * m4sugar/version.m4: Remove; it was included but it wasn't used.
- * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
- * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
- * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
- * src/output.c (output_skeleton): Use full path names when
- specifying a file to include; don't rely on include path, as
- it's unreliable when the working file contains a file with
- that name.
-
-2002-12-25 Paul Eggert <eggert@twinsun.com>
-
- Remove obsolete references to bison.simple and bison.hairy.
- Problem mentioned by Aubin Mahe in
- <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
- * data/glr.c: Comment fix.
- * doc/bison.1: Remove references. Also, mention "yacc".
-
- * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
- with -g option.
-
- * src/parse-gram.y (declaration): Use enum "report_states" rather
- than its numeric value 1.
-
- * src/scan-skel.l ("@output ".*\n): Close any old yyout before
- opening a new one. This fixes Debian bug 165349, reported by
- Bruce Stephens.
-
-2002-12-24 Paul Eggert <eggert@twinsun.com>
-
- Version 1.75e.
-
- * Makefile.maint (cvs-update): Don't assume that the shell
- supports $(...), as Solaris sh doesn't.
-
- * src/parse-gram.y (lloc_default): Remove test for empty
- nonterminals at the end, since it didn't change the result.
-
-2002-12-24 Paul Eggert <eggert@twinsun.com>
-
- If the user does not define YYSTYPE as a macro, Bison now declares it
- using typedef instead of defining it as a macro. POSIX requires this.
- For consistency, YYLTYPE is also declared instead of defined.
-
- %union directives can now have a tag before the `{', e.g., the
- directive `%union foo {...}' now generates the C code
- `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
- The default union tag is `YYSTYPE', for compatibility with Solaris 9
- Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
- instead of `yyltype'.
-
- `yystype' and `yyltype' are now obsolescent macros instead of being
- typedefs or tags; they are no longer documented and will be
- withdrawn in a future release.
-
- * data/glr.c (b4_location_type): Remove.
- (YYSTYPE): Renamed from yystype.
- (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
- (struct YYLTYPE): Renamed from struct yyltype.
- (YYLTYPE): Renamed from yyltype.
- (yyltype, yystype): New (and obsolescent) macros,
- for backward compatibility.
- * data/yacc.c: Likewise.
-
- * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
- does not specify a union tag. This is for compatibility with
- Solaris 9 yacc.
-
- * src/parse-gram.y (add_param): 2nd arg is now char * not char
- const *, since it is now modified by stripping surrounding { }.
- (current_braced_code): Remove.
- (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
- PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
- trailing " {...}". Now of type <chars>.
- (grammar_declaration): Adjust to bundled tokens.
- (code_content): Remove; stripping is now done by add_param.
- (print_token_value): Print contents of bundled tokens.
- (token_name): New function.
-
- * src/reader.h (braced_code, current_braced_code): Remove.
- (token_name): New decl.
-
- * src/scan-gram.l (handle_dollar, handle_at): Now takes int
- token_type, not braced_code code_kind. All uses changed.
- (SC_PRE_CODE): New state, for scanning after a keyword that
- has (or usually has) an immediately-following braced code.
- (token_type): New local var, to keep track of which token type
- to return when scanning braced code.
- (<INITIAL>"%destructor", <INITIAL>"%lex-param",
- <INITIAL>"%parse-param", <INITIAL>"%printer",
- <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
- instead of returning a token type immediately.
- (<INITIAL>"{"): Set token type.
- (<SC_BRACED_CODE>"}"): Use it.
- (handle_action_dollar, handle_action_at): Now returns bool
- indicating success. Fail if ! current_rule; this prevents a core dump.
- (handle_symbol_code_dollar, handle_symbol_code_at):
- Remove; merge body into caller.
- (handle_dollar, handle_at): Complain in invalid contexts.
-
- * NEWS, doc/bison.texinfo: Document the above.
- * NEWS: Fix years and program names in copyright notice.
-
-2002-12-17 Paul Eggert <eggert@twinsun.com>
-
- * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
- Reporting, Table of Symbols): Omit mentions of %lex-param and
- %parse-param from the documentation for now.
-
-2002-12-15 Paul Eggert <eggert@twinsun.com>
-
- Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
- GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
- lookahead symbol, and which sets yychar in parser actions) and it
- disagreed with the Bison documentation. Bug
- reported by Andrew Walrond.
-
- * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
- as the caller now does that.
- (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
- (YYEMPTY): Parenthesize right hand side, since others use it.
- (yyparse): Don't assume that our generated code is the only code
- that sets yychar.
-
-2002-12-13 Paul Eggert <eggert@twinsun.com>

-
- Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in

- locations are requested.
- (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
- locations are requested.
-
-2002-12-12 Paul Eggert <eggert@twinsun.com>
-
- Remove unportable casts and storage allocation tricks.
- While we're at it, remove almost all casts, since they
- usually aren't needed and are a sign of trouble.
-
- * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
-
- * src/derives.c (derives_compute): Do not subtract NTOKENS from
- the pointer DSET returned by malloc; this isn't portable.

- space.
- From Tim Van Holder.
-
-2002-11-17 Paul Eggert <eggert@twinsun.com>
-
- Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
- to "SyntaxError" for consistency with my 2002-11-15 change.
-
- * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
- not define to {}, since this breaks the common use of `YYDPRINTF
- ((...));' if a single statement is desired (e.g. before `else').
- Work around GCC warnings by surrounding corresponding calls with
- {} if needed.
- (yyhasResolvedValue): Remove unused function.
- (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
- loop body.
- (yyreportSyntaxError): Renamed from yyreportParseError.

- state reached after the reduction/recovery, since...
- (yyparse, yyprocessOneStack): Report the state we are entering in.
-
-2002-11-16 Akim Demaille <akim@epita.fr>
-
- * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
- Add support for --trace=skeleton.

- * data/lalr1.cc: Likewise.
- The header guards are no longer available, so use some other
- string than `YYLSP_NEEDED'.
-
-2002-11-16 Akim Demaille <akim@epita.fr>
-
- Make the ``Printers and Destructors'' test more verbose, taking
- `yacc.c''s behavior as (possibly wrong) reference.
-
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
- instead of fprint on stdout.
- Set and report the last_line of the symbols.

-
- * data/yacc.c: Avoid over-quoting of __line__ and __file__.
-
-2002-11-15 Paul Eggert <eggert@twinsun.com>
-
- * tests/actions.at (Actions after errors): New test case.
-
- * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
- src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
- tests/action.at, tests/calc.at, tests/conflicts.at,
- tests/cxx-type.at, tests/regression.at:
- "parse error" -> "syntax error" for POSIX compatibility.
- "parsing stack overflow..." -> "parser stack overflow" so
- that code matches Bison documentation.
-
-2002-11-15 Akim Demaille <akim@epita.fr>
-
- * src/parse-gram.y (declaration): Have %parse-param and %lex-param
- take two BRACED_CODE, not two string_content.

- duplicating xfopen's body.
-
- Fix bugs reported by Nelson H. F. Beebe in
- <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
-
- * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
- "$CC -E foo.h" is allowed, as this doesn't work with the Portland
- Group compiler. Instead, use "$CC -E bar.c". Include the .h
- file twice in the grammar, as an extra check.
-
- * tests/input.at (Torturing the Scanner): Surround the
- backslash-newline tests with "#if 0", to make it less likely that
- we'll run into compiler bugs. Bring back solitary \ inside
- comment, but add a closing comment to work around HP C bug. Don't
- test backslash-newline in C character constant.
-
-2002-11-14 Akim Demaille <akim@epita.fr>
-
- * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit

-
-2002-11-14 Akim Demaille <akim@epita.fr>
-
- * doc/bison.texinfo: Various formatting changes (alignments in
- samples, additional @group/@end group, GCS in samples.
- Use @deffn instead of simple @table to define the directives,
- macros, variables etc.
-
-2002-11-13 Paul Eggert <eggert@twinsun.com>
-
- Fix some bugs reported by Albert Chin-A-Young in
- <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
-
- * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
- -o c"; the HP C compiler chatters during compilation.
- Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
- * tests/headers.at (export YYLTYPE): Likewise.
-
- * tests/input.at (Torturing the Scanner): Remove lines containing
- solitary backslashes, as they tickle a bug in the HP C compiler.
-
- * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
- comments, since they're not portable. Use GNU coding style.
-
-2002-11-13 Akim Demaille <akim@epita.fr>
-
- * data/yacc.c: Leave bigger chunks of quoted text.
- (YYDSYMPRINTF): New.

-
-2002-11-12 Paul Eggert <eggert@twinsun.com>
-
- Version 1.75b.
-
- * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
- (yyglrReduce): Return yyok, not 0.

- responsibility to #define it away, just like 'const'.
- This fixes one of the bugs reported by Nelson H. F. Beebe in
- <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
-
- * Makefile.maint (po-check): Scan .l and .y files instead of the
- .c and the .h files that they generate. This fixes the bug
- reported by Tim Van Holder in:
- <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
- Look for N_ as well as for _. Try to avoid matching #define for
- N_ and _.
- * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
- src/system.h. Add src/parse-gram.y, src/scan-gram.l.
- * src/scan-gram.l: Revamp regular expressions so that " and '
- do not confuse xgettext.
-
- * src/struniq.h (struniq_new): Do not declare the return type
- to be 'const'; this violates the C standard.

-
-2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
-
- * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the

-
-2002-11-12 Akim Demaille <akim@epita.fr>
-
- * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
- defines it.
- * data/glr.c (yystos): New.
- (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
- (YYDSYMPRINT): New.
- (yyval): Don't define it, it is handled via M4.
- (yyrecoverParseError): Free verbosely the discarded symbols.
- * data/yacc.c (yysymprint): Remove, rather...

- * tests/cations.at (Printers and Destructors): Use Bison directives
- instead of CPP macros.
- Don't rely on internal details.
-
-2002-11-12 Akim Demaille <akim@epita.fr>
-
- * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
- * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.

- it to YYEMPTY etc.).
- (yydestruct): Replace with a b4_yydestruct_generate invocation.
- (b4_symbol_actions): Remove.
- * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands

- Restore.
- * src/scan-gram.l (last_string): Is global to the file, not to
- yylex.

-
-2002-11-11 Paul Eggert <eggert@twinsun.com>
-
- Revamp to fix many (but not all) of the C- and M4-related quoting
- problems. Among other things, this fixes the Bison bug reported
- by Jan Hubicka when processing the Bash grammar; see:
- <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
-
- Use new @ escapes consistently. Represent brackets with @{ and @}
- rather than @<:@ and @:>@, since this works a bit better with dumb
- editors like vi. Represent @ with @@, since @ is now consistently
- an escape. Use @oline@ and @ofile@ rather than __oline__ and
- __ofile__, to avoid unexpected expansions. Similarly, use @output
- rather than #output.
-
- * data/c.m4 (b4_copyright): Omit file name from comment, since
- the file name could contain "*/".
- (b4_synclines_flag): Don't quote the 2nd argument; it should already
- be quoted. All uses changed.

- (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
- b4_output_header_suffix, b4_output_header_name, b4_header_guard):
- Remove, since they couldn't handle arbitrary characters in file

- * data/yacc.c: Likewise.
-
- * src/files.c (output_infix): Remove; all uses removed.
- * src/files.h: Likewise.

- mishandled funny characters in file names, and anyway it isn't
- needed any more.
- * data/yacc.c: Likewise.
- * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
-
- * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
- * data/yacc.c: Likewise.
-
- * src/muscle_tab.c: Include quotearg.h, since we need to quote C
- strings now.

- * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
- (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
- * src/output.c (escaped_file_name_output): New function.
- (prepare_symbols): Quote tokens for M4.
- (prepare): Don't insert output_infix, output_prefix,
- output_parser_name, output_header_name; this is now down by scan-skel.
- Insert skeleton as a C string.
-
- * src/output.c (user_actions_output, symbol_destructors_output,
- symbol_printers_output): Quote filenames for C and M4.
- * src/reader.c (prologue_augment, epilogue_set): Likewise.
-
- * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
- escapes other than \\ and \'; this simplifies the code.
- (<SC_STRING>): Likewise, for \\ and \".
- (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
- SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
- Use new escapes @{ and @} for [ and ].
-
- * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
- them with auto vars.
- Switch to new escape scheme, where @ is the escape character uniformly.
- Abort if a stray escape character is found. Avoid unbounded input
- buffer when parsing non-escaped text.
-
- * tests/input.at (Torturing the Scanner): Add tests that @oline@,
- __oline__, #output, $@, and @{ do not have unintended meanings.
-
-2002-11-09 Paul Eggert <eggert@twinsun.com>
-
- Fix the test failure due to GCC warnings described in
- <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
- * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
- evaluate to 0 if it's impossible for NINF to be in the respective
- table.
- (yygetLRActions, yyrecoverParseError): Use them.
-
- * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
- counted in the token inserted at end of file. Now takes
- location_t *, not location_t, so that the location can be
- adjusted. All uses changed.
-
- * tests/regression.at (Invalid inputs): Adjust wording in
- diagnostic to match the new behavior.
-
- * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
- AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
- AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
- abort ();'. This reduces the runtime of the "Many lookaheads"
- test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
- GCC 3.2.
-
-2002-11-07 Paul Eggert <eggert@twinsun.com>
-
- * src/parse-gram.y (CHARACTER): Remove unused token.
- All uses removed.
-
- * src/scan-gram.l: Remove stack option. We no longer use the
- stack, since the stack was never deeper than 1; instead, use the
- new auto var c_context to record the stacked value.
-
- Remove nounput option. At an unexpected end of file, we now unput
- the minimal input necessary to end cleanly; this simplifies the
- code.
-
- Avoid unbounded token sizes where this is easy.
-
- (unexpected_end_of_file): New function.
- Use it to systematize the error message on unexpected EOF.
- (last-string): Now auto, not static.
- (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
- (scanner_last_string_free): Remove; not used.
- (percent_percent_count): Move decl to just before use.
- (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
- not the (never otherwised-used) CHARACTER.
-
-2002-11-07 Akim Demaille <akim@epita.fr>
-
- Let yyerror always receive the msg as last argument, so that
- yyerror can be variadic.
-
- * data/yacc.c (b4_yyerror_args): New.
- Use it when calling yyerror.
- * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.

- (symbol_printers_output): Use the location's file name, not
- infile.
- * src/reader.c (prologue_augment, epilogue_set): Likewise.
-
-2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
-
- * src/tables.c (matching_state): Don't allow states to match if
- either has GLR conflict entries.
-
-2002-11-05 Paul Eggert <eggert@twinsun.com>
-
- * src/scan-gram.l: Use more accurate diagnostics, e.g.
- "integer out of range" rather than "invalid value".
- * tests/input.at (Invalid $n, Invalid @n): Change expected wording
- accordingly.
-
- Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
- Also, remove one static variable in the scanner.
-
- * src/scan-gram.l (braces_level): Now auto, not static.
- Initialize to zero if the compiler is being picky.

-
-2002-10-24 Akim Demaille <akim@epita.fr>
-
- * src/output.c (output_skeleton): Don't disable M4sugar comments

- doing locations. This is more consistent with yacc.c, and it
- works around the following bug reports:
- http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
- http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html

-
- * data/README: New.
-
-2002-10-21 Paul Eggert <eggert@twinsun.com>

-
- Let nondeterministic skeletons be usable with deterministic
- tables.
-
- With the patch, GAWK compiled by GCC without -O2 passes its test
- suite using a GLR parser driven by LALR tables. It fails with -O2
- because `struct stat' gives two different answers on my machine:
- 88 (definition of an auto var) and later 96 (memset on this var).
- Hence the stack is badly corrumpted. The headers inclusion is to
- blame: if I move the awk.h inclusion before GLR's system header
- inclusion, the two struct stat have the same size.
-
- * src/tables.c (pack_table): Always create conflict_table.
- (token_actions): Always create conflict_list.

-2002-10-13 Akim Demaille <akim@epita.fr>
-
- GLR parsers sometimes raise parse errors instead of performing the

- (yyltype): Remove the yy prefix from the member names.
- (yytable): Complete its comment.
- (yygetLRActions): Map error action number from YYTABLE from
- YYTABLE_NINF to 0.
- (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
- (which was a bug: it should have been YYTABEL_NINF, and yet it was
- not satisfying as we could compare an YYACTION computed from
- YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
- only value for error actions.
- (yyreportParseError): In verbose parse error messages, don't issue
- `error' in the list of expected tokens.
- * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the

- Fix problem reported by Henrik Grubbstroem in
- <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
- "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
- because the Bison parser reads the second action before reducing
- the first one.
- * src/scan-gram.l (rule_length): New static var.
- Use it to keep track of the rule length in the scanner, since
- we can't expect the parser to be in lock-step sync with the scanner.
- (handle_action_dollar, handle_action_at): Use this var.
- * tests/actions.at (Exotic Dollars): Test for the problem.

- PROTOTYPES to check for prototypes, and "defined __STDC__" to
- check for void *.

- * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
- size_t; the old version tried to do this but casted improperly.
- (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
- (bitset_test): Now returns int, not unsigned long.
-
- * lib/bitset_stats.c: Include "gettext.h".
- (_): New macro.
- (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
- name locals "index", as it generates unnecessary warnings on some
- hosts that have an "index" function.
-
- * lib/bitset_stats.c (bitset_stats_print_1, bitset_stats_print,
- bitset_stats_read, bitset_stats_write): Wrap strings in _() if

- Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
- manual recommends.
- Similarly, use src/scan-gram.l instead of src/scan-gram.c.
-
- * src/complain.c (strerror_r): Remove decl; not needed.
- (strerror): Use same pattern as ../lib/error.c.
-
- * src/files.c, src/files.h (compute_header_macro): Remove; unused.
-
- * src/gram.c (grammar_dump): Do not assume ptrdiff_t fits in int.

-
- * src/scan-gram.l: Use strings rather than escapes when possible,
- to minimize the number of warnings from xgettext.
- (handle_action_dollar, handle_action_at): Don't use isdigit,
- as it mishandles negative chars and it may not work as expected
- outside the C locale.
-
- * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
- this is a GCC extension and is not portable to other compilers.
-
- * src/system.h (alloca): Use same pattern as ../lib/error.c.
- Do not include <ctype.h>; no longer needed.
- Do not include <malloc.h>; no longer needed (and generates
- warnings on OpenBSD 3.0).
-
- * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
- it's not portable.
-
- * tests/regression.at: Do not use 'cc -c input.c -o input';
- Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
-
- * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
- exit status as failure, not just exit status 1. Sun C exits
- with status 2 sometimes.
-
- * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
- Use it for the two large tests.
-
-2002-08-02 Akim Demaille <akim@epita.fr>

-
-2002-08-01 Akim Demaille <akim@epita.fr>
