+/* Thanks to Mike Haertel and Jim Avera for this test.
+ Here is a matrix of mmap possibilities:
+ mmap private not fixed
+ mmap private fixed at somewhere currently unmapped
+ mmap private fixed at somewhere already mapped
+ mmap shared not fixed
+ mmap shared fixed at somewhere currently unmapped
+ mmap shared fixed at somewhere already mapped
+ For private mappings, we should verify that changes cannot be read()
+ back from the file, nor mmap's back from the file at a different
+ address. (There have been systems where private was not correctly
+ implemented like the infamous i386 svr4.0, and systems where the
+ VM page cache was not coherent with the filesystem buffer cache
+ like early versions of FreeBSD and possibly contemporary NetBSD.)
+ For shared mappings, we should conversely verify that changes get
+ propogated back to all the places they're supposed to be.
+
+ Grep wants private fixed already mapped.
+ The main things grep needs to know about mmap are:
+ * does it exist and is it safe to write into the mmap'd area
+ * how to use it (BSD variants) */

+ --- The Detailed Node Listing ---
+
+The Concepts of Bison
+
+* Language and Grammar:: Languages and context-free grammars,
+ as mathematical ideas.
+* Grammar in Bison:: How we represent grammars for Bison's sake.
+* Semantic Values:: Each token or syntactic grouping can have
+ a semantic value (the value of an integer,
+ the name of an identifier, etc.).
+* Semantic Actions:: Each rule can have an action containing C code.
+* Bison Parser:: What are Bison's input and output,
+ how is the output used?
+* Stages:: Stages in writing and running Bison grammars.
+* Grammar Layout:: Overall structure of a Bison grammar file.
+
+Examples
+
+* RPN Calc:: Reverse polish notation calculator;
+ a first example with no operator precedence.
+* Infix Calc:: Infix (algebraic) notation calculator.
+ Operator precedence is introduced.
+* Simple Error Recovery:: Continuing after syntax errors.
+* Multi-function Calc:: Calculator with memory and trig functions.
+ It uses multiple data-types for semantic values.
+* Exercises:: Ideas for improving the multi-function calculator.
+
+Reverse Polish Notation Calculator
+
+* Decls: Rpcalc Decls. Bison and C declarations for rpcalc.
+* Rules: Rpcalc Rules. Grammar Rules for rpcalc, with explanation.
+* Lexer: Rpcalc Lexer. The lexical analyzer.
+* Main: Rpcalc Main. The controlling function.
+* Error: Rpcalc Error. The error reporting function.
+* Gen: Rpcalc Gen. Running Bison on the grammar file.
+* Comp: Rpcalc Compile. Run the C compiler on the output code.
+
+Grammar Rules for `rpcalc'
+
+* Rpcalc Input::
+* Rpcalc Line::
+* Rpcalc Expr::
+
+Multi-Function Calculator: `mfcalc'
+
+* Decl: Mfcalc Decl. Bison declarations for multi-function calculator.
+* Rules: Mfcalc Rules. Grammar rules for the calculator.
+* Symtab: Mfcalc Symtab. Symbol table management subroutines.
+
+Bison Grammar Files
+
+* Grammar Outline:: Overall layout of the grammar file.
+* Symbols:: Terminal and nonterminal symbols.
+* Rules:: How to write grammar rules.
+* Recursion:: Writing recursive rules.
+* Semantics:: Semantic values and actions.
+* Declarations:: All kinds of Bison declarations are described here.
+* Multiple Parsers:: Putting more than one Bison parser in one program.
+
+Outline of a Bison Grammar
+
+* C Declarations:: Syntax and usage of the C declarations section.
+* Bison Declarations:: Syntax and usage of the Bison declarations section.
+* Grammar Rules:: Syntax and usage of the grammar rules section.
+* C Code:: Syntax and usage of the additional C code section.
+
+Defining Language Semantics
+
+* Value Type:: Specifying one data type for all semantic values.
+* Multiple Types:: Specifying several alternative data types.
+* Actions:: An action is the semantic definition of a grammar rule.
+* Action Types:: Specifying data types for actions to operate on.
+* Mid-Rule Actions:: Most actions go at the end of a rule.
+ This says when, why and how to use the exceptional
+ action in the middle of a rule.
+
+Bison Declarations
+
+* Token Decl:: Declaring terminal symbols.
+* Precedence Decl:: Declaring terminals with precedence and associativity.
+* Union Decl:: Declaring the set of all semantic value types.
+* Type Decl:: Declaring the choice of type for a nonterminal symbol.

+Introduction
+************
+
+ "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. Once you are proficient with Bison, you
+may use it to develop a wide range of language parsers, from those used
+in simple desk calculators to complex programming languages.
+
+ Bison is upward compatible with Yacc: all properly-written Yacc
+grammars ought to work with Bison with no change. Anyone familiar with
+Yacc should be able to use Bison with little trouble. You need to be
+fluent in C programming in order to use Bison or to understand this
+manual.
+
+ We begin with tutorial chapters that explain the basic concepts of
+using Bison and show three explained examples, each building on the
+last. If you don't know Bison or Yacc, start by reading these
+chapters. Reference chapters follow which describe specific aspects of
+Bison in detail.
+
+ Bison was written primarily by Robert Corbett; Richard Stallman made
+it Yacc-compatible. Wilfred Hansen of Carnegie Mellon University added
+multi-character string literals and other features.
+
+ This edition corresponds to version 1.28a of Bison.

+
+Conditions for Using Bison
+**************************
+
+ As of Bison version 1.24, we have changed the distribution terms for
+`yyparse' to permit using Bison's output in nonfree programs.
+Formerly, Bison parsers could be used only in programs that were free
+software.
+
+ The other GNU programming tools, such as the GNU C compiler, have
+never had such a requirement. They could always be used for nonfree
+software. The reason Bison was different was not due to a special
+policy decision; it resulted from applying the usual General Public
+License to all of the Bison source code.
+
+ The output of the Bison utility--the Bison parser file--contains a
+verbatim copy of a sizable piece of Bison, which is the code for the
+`yyparse' function. (The actions from your grammar are inserted into
+this function at one point, but the rest of the function is not
+changed.) When we applied the GPL terms to the code for `yyparse', the
+effect was to restrict the use of Bison output to free software.
+
+ We didn't change the terms because of sympathy for people who want to
+make software proprietary. *Software should be free.* But we
+concluded that limiting Bison's use to free software was doing little to
+encourage people to make other software free. So we decided to make the
+practical conditions for using Bison match the practical conditions for
+using the other GNU tools.

+**************************
+
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
+
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+Preamble
+========
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it in
+new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software,
+and (2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains a
+ notice placed by the copyright holder saying it may be distributed
+ under the terms of this General Public License. The "Program",
+ below, refers to any such program or work, and a "work based on
+ the Program" means either the Program or any derivative work under
+ copyright law: that is to say, a work containing the Program or a
+ portion of it, either verbatim or with modifications and/or
+ translated into another language. (Hereinafter, translation is
+ included without limitation in the term "modification".) Each
+ licensee is addressed as "you".
+
+ Activities other than copying, distribution and modification are
+ not covered by this License; they are outside its scope. The act
+ of running the Program is not restricted, and the output from the
+ Program is covered only if its contents constitute a work based on
+ the Program (independent of having been made by running the
+ Program). Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+ source code as you receive it, in any medium, provided that you
+ conspicuously and appropriately publish on each copy an appropriate
+ copyright notice and disclaimer of warranty; keep intact all the
+ notices that refer to this License and to the absence of any
+ warranty; and give any other recipients of the Program a copy of
+ this License along with the Program.
+
+ You may charge a fee for the physical act of transferring a copy,
+ and you may at your option offer warranty protection in exchange
+ for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+ of it, thus forming a work based on the Program, and copy and
+ distribute such modifications or work under the terms of Section 1
+ above, provided that you also meet all of these conditions:
+
+ a. You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b. You must cause any work that you distribute or publish, that
+ in whole or in part contains or is derived from the Program
+ or any part thereof, to be licensed as a whole at no charge
+ to all third parties under the terms of this License.
+
+ c. If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display
+ an announcement including an appropriate copyright notice and
+ a notice that there is no warranty (or else, saying that you
+ provide a warranty) and that users may redistribute the
+ program under these conditions, and telling the user how to
+ view a copy of this License. (Exception: if the Program
+ itself is interactive but does not normally print such an
+ announcement, your work based on the Program is not required
+ to print an announcement.)
+
+ These requirements apply to the modified work as a whole. If
+ identifiable sections of that work are not derived from the
+ Program, and can be reasonably considered independent and separate
+ works in themselves, then this License, and its terms, do not
+ apply to those sections when you distribute them as separate
+ works. But when you distribute the same sections as part of a
+ whole which is a work based on the Program, the distribution of
+ the whole must be on the terms of this License, whose permissions
+ for other licensees extend to the entire whole, and thus to each
+ and every part regardless of who wrote it.
+
+ Thus, it is not the intent of this section to claim rights or
+ contest your rights to work written entirely by you; rather, the
+ intent is to exercise the right to control the distribution of
+ derivative or collective works based on the Program.
+
+ In addition, mere aggregation of another work not based on the
+ Program with the Program (or with a work based on the Program) on
+ a volume of a storage or distribution medium does not bring the
+ other work under the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+ under Section 2) in object code or executable form under the terms
+ of Sections 1 and 2 above provided that you also do one of the
+ following:
+
+ a. Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of
+ Sections 1 and 2 above on a medium customarily used for
+ software interchange; or,
+
+ b. Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a
+ medium customarily used for software interchange; or,
+
+ c. Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with
+ such an offer, in accord with Subsection b above.)
+
+ The source code for a work means the preferred form of the work for
+ making modifications to it. For an executable work, complete
+ source code means all the source code for all modules it contains,
+ plus any associated interface definition files, plus the scripts
+ used to control compilation and installation of the executable.
+ However, as a special exception, the source code distributed need
+ not include anything that is normally distributed (in either
+ source or binary form) with the major components (compiler,
+ kernel, and so on) of the operating system on which the executable
+ runs, unless that component itself accompanies the executable.
+
+ If distribution of executable or object code is made by offering
+ access to copy from a designated place, then offering equivalent
+ access to copy the source code from the same place counts as
+ distribution of the source code, even though third parties are not
+ compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+ except as expressly provided under this License. Any attempt
+ otherwise to copy, modify, sublicense or distribute the Program is
+ void, and will automatically terminate your rights under this
+ License. However, parties who have received copies, or rights,
+ from you under this License will not have their licenses
+ terminated so long as such parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+ signed it. However, nothing else grants you permission to modify
+ or distribute the Program or its derivative works. These actions
+ are prohibited by law if you do not accept this License.
+ Therefore, by modifying or distributing the Program (or any work
+ based on the Program), you indicate your acceptance of this
+ License to do so, and all its terms and conditions for copying,
+ distributing or modifying the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+ Program), the recipient automatically receives a license from the
+ original licensor to copy, distribute or modify the Program
+ subject to these terms and conditions. You may not impose any
+ further restrictions on the recipients' exercise of the rights
+ granted herein. You are not responsible for enforcing compliance
+ by third parties to this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+ infringement or for any other reason (not limited to patent
+ issues), conditions are imposed on you (whether by court order,
+ agreement or otherwise) that contradict the conditions of this
+ License, they do not excuse you from the conditions of this
+ License. If you cannot distribute so as to satisfy simultaneously
+ your obligations under this License and any other pertinent
+ obligations, then as a consequence you may not distribute the
+ Program at all. For example, if a patent license would not permit
+ royalty-free redistribution of the Program by all those who
+ receive copies directly or indirectly through you, then the only
+ way you could satisfy both it and this License would be to refrain
+ entirely from distribution of the Program.
+
+ If any portion of this section is held invalid or unenforceable
+ under any particular circumstance, the balance of the section is
+ intended to apply and the section as a whole is intended to apply
+ in other circumstances.
+
+ It is not the purpose of this section to induce you to infringe any
+ patents or other property right claims or to contest validity of
+ any such claims; this section has the sole purpose of protecting
+ the integrity of the free software distribution system, which is
+ implemented by public license practices. Many people have made
+ generous contributions to the wide range of software distributed
+ through that system in reliance on consistent application of that
+ system; it is up to the author/donor to decide if he or she is
+ willing to distribute software through any other system and a
+ licensee cannot impose that choice.
+
+ This section is intended to make thoroughly clear what is believed
+ to be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+ certain countries either by patents or by copyrighted interfaces,
+ the original copyright holder who places the Program under this
+ License may add an explicit geographical distribution limitation
+ excluding those countries, so that distribution is permitted only
+ in or among countries not thus excluded. In such case, this
+ License incorporates the limitation as if written in the body of
+ this License.
+
+ 9. The Free Software Foundation may publish revised and/or new
+ versions of the General Public License from time to time. Such
+ new versions will be similar in spirit to the present version, but
+ may differ in detail to address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+ Program specifies a version number of this License which applies
+ to it and "any later version", you have the option of following
+ the terms and conditions either of that version or of any later
+ version published by the Free Software Foundation. If the Program
+ does not specify a version number of this License, you may choose
+ any version ever published by the Free Software Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+ programs whose distribution conditions are different, write to the
+ author to ask for permission. For software which is copyrighted
+ by the Free Software Foundation, write to the Free Software
+ Foundation; we sometimes make exceptions for this. Our decision
+ will be guided by the two goals of preserving the free status of
+ all derivatives of our free software and of promoting the sharing
+ and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO
+ WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
+ LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+ HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT
+ WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT
+ NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND
+ FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE
+ QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+ PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY
+ SERVICING, REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+ WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY
+ MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE
+ LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
+ INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
+ INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+ DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU
+ OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY
+ OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN
+ ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+ 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
+convey 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.

+
+Languages and Context-Free Grammars
+===================================
+
+ In order for Bison to parse a language, it must be described by a
+"context-free grammar". This means that you specify one or more
+"syntactic groupings" and give rules for constructing them from their
+parts. For example, in the C language, one kind of grouping is called
+an `expression'. One rule for making an expression might be, "An
+expression can be made of a minus sign and another expression".
+Another would be, "An expression can be an integer". As you can see,
+rules are often recursive, but there must be at least one rule which
+leads out of the recursion.
+
+ The most common formal system for presenting such rules for humans
+to read is "Backus-Naur Form" or "BNF", which was developed in order to
+specify the language Algol 60. Any grammar expressed in BNF is a
+context-free grammar. The input to Bison is essentially
+machine-readable BNF.
+
+ Not all context-free languages can be handled by Bison, only those
+that are LALR(1). In brief, this means that it must be possible to
+tell how to parse any portion of an input string with just a single
+token of look-ahead. Strictly speaking, that is a description of an
+LR(1) grammar, and LALR(1) involves additional restrictions that are
+hard to explain simply; but it is rare in actual practice to find an
+LR(1) grammar that fails to be LALR(1). *Note Mysterious Reduce/Reduce
+Conflicts: Mystery Conflicts, for more information on this.
+
+ In the formal grammatical rules for a language, each kind of
+syntactic unit or grouping is named by a "symbol". Those which are
+built by grouping smaller constructs according to grammatical rules are
+called "nonterminal symbols"; those which can't be subdivided are called
+"terminal symbols" or "token types". We call a piece of input
+corresponding to a single terminal symbol a "token", and a piece
+corresponding to a single nonterminal symbol a "grouping".
+
+ We can use the C language as an example of what symbols, terminal and
+nonterminal, mean. The tokens of C are identifiers, constants (numeric
+and string), and the various keywords, arithmetic operators and
+punctuation marks. So the terminal symbols of a grammar for C include
+`identifier', `number', `string', plus one symbol for each keyword,
+operator or punctuation mark: `if', `return', `const', `static', `int',
+`char', `plus-sign', `open-brace', `close-brace', `comma' and many
+more. (These tokens can be subdivided into characters, but that is a
+matter of lexicography, not grammar.)
+
+ Here is a simple C function subdivided into tokens:
+
+ int /* keyword `int' */
+ square (x) /* identifier, open-paren, */
+ /* identifier, close-paren */
+ int x; /* keyword `int', identifier, semicolon */
+ { /* open-brace */
+ return x * x; /* keyword `return', identifier, */
+ /* asterisk, identifier, semicolon */
+ } /* close-brace */
+
+ The syntactic groupings of C include the expression, the statement,
+the declaration, and the function definition. These are represented in
+the grammar of C by nonterminal symbols `expression', `statement',
+`declaration' and `function definition'. The full grammar uses dozens
+of additional language constructs, each with its own nonterminal
+symbol, in order to express the meanings of these four. The example
+above is a function definition; it contains one declaration, and one
+statement. In the statement, each `x' is an expression and so is `x *
+x'.
+
+ Each nonterminal symbol must have grammatical rules showing how it
+is made out of simpler constructs. For example, one kind of C
+statement is the `return' statement; this would be described with a
+grammar rule which reads informally as follows:
+
+ A `statement' can be made of a `return' keyword, an `expression'
+ and a `semicolon'.
+
+There would be many other rules for `statement', one for each kind of
+statement in C.
+
+ One nonterminal symbol must be distinguished as the special one which
+defines a complete utterance in the language. It is called the "start
+symbol". In a compiler, this means a complete input program. In the C
+language, the nonterminal symbol `sequence of definitions and
+declarations' plays this role.
+
+ For example, `1 + 2' is a valid C expression--a valid part of a C
+program--but it is not valid as an _entire_ C program. In the
+context-free grammar of C, this follows from the fact that `expression'
+is not the start symbol.
+
+ The Bison parser reads a sequence of tokens as its input, and groups
+the tokens using the grammar rules. If the input is valid, the end
+result is that the entire token sequence reduces to a single grouping
+whose symbol is the grammar's start symbol. If we use a grammar for C,
+the entire input must be a `sequence of definitions and declarations'.
+If not, the parser reports a syntax error.
+

+
+From Formal Rules to Bison Input
+================================
+
+ A formal grammar is a mathematical construct. To define the language
+for Bison, you must write a file expressing the grammar in Bison syntax:
+a "Bison grammar" file. *Note Bison Grammar Files: Grammar File.
+
+ A nonterminal symbol in the formal grammar is represented in Bison
+input as an identifier, like an identifier in C. By convention, it
+should be in lower case, such as `expr', `stmt' or `declaration'.
+
+ The Bison representation for a terminal symbol is also called a
+"token type". Token types as well can be represented as C-like
+identifiers. By convention, these identifiers should be upper case to
+distinguish them from nonterminals: for example, `INTEGER',
+`IDENTIFIER', `IF' or `RETURN'. A terminal symbol that stands for a
+particular keyword in the language should be named after that keyword
+converted to upper case. The terminal symbol `error' is reserved for
+error recovery. *Note Symbols::.
+
+ A terminal symbol can also be represented as a character literal,
+just like a C character constant. You should do this whenever a token
+is just a single character (parenthesis, plus-sign, etc.): use that
+same character in a literal as the terminal symbol for that token.
+
+ A third way to represent a terminal symbol is with a C string
+constant containing several characters. *Note Symbols::, for more
+information.
+
+ The grammar rules also have an expression in Bison syntax. For
+example, here is the Bison rule for a C `return' statement. The
+semicolon in quotes is a literal character token, representing part of
+the C syntax for the statement; the naked semicolon, and the colon, are
+Bison punctuation used in every rule.
+
+ stmt: RETURN expr ';'

+
+Semantic Values
+===============
+
+ A formal grammar selects tokens only by their classifications: for
+example, if a rule mentions the terminal symbol `integer constant', it
+means that _any_ integer constant is grammatically valid in that
+position. The precise value of the constant is irrelevant to how to
+parse the input: if `x+4' is grammatical then `x+1' or `x+3989' is
+equally grammatical.
+
+ But the precise value is very important for what the input means
+once it is parsed. A compiler is useless if it fails to distinguish
+between 4, 1 and 3989 as constants in the program! Therefore, each
+token in a Bison grammar has both a token type and a "semantic value".
+*Note Defining Language Semantics: Semantics, for details.
+
+ The token type is a terminal symbol defined in the grammar, such as
+`INTEGER', `IDENTIFIER' or `',''. It tells everything you need to know
+to decide where the token may validly appear and how to group it with
+other tokens. The grammar rules know nothing about tokens except their
+types.
+
+ The semantic value has all the rest of the information about the
+meaning of the token, such as the value of an integer, or the name of an
+identifier. (A token such as `','' which is just punctuation doesn't
+need to have any semantic value.)
+
+ For example, an input token might be classified as token type
+`INTEGER' and have the semantic value 4. Another input token might
+have the same token type `INTEGER' but value 3989. When a grammar rule
+says that `INTEGER' is allowed, either of these tokens is acceptable
+because each is an `INTEGER'. When the parser accepts the token, it
+keeps track of the token's semantic value.
+
+ Each grouping can also have a semantic value as well as its
+nonterminal symbol. For example, in a calculator, an expression
+typically has a semantic value that is a number. In a compiler for a
+programming language, an expression typically has a semantic value that
+is a tree structure describing the meaning of the expression.

+
+Semantic Actions
+================
+
+ In order to be useful, a program must do more than parse input; it
+must also produce some output based on the input. In a Bison grammar,
+a grammar rule can have an "action" made up of C statements. Each time
+the parser recognizes a match for that rule, the action is executed.
+*Note Actions::.
+
+ Most of the time, the purpose of an action is to compute the
+semantic value of the whole construct from the semantic values of its
+parts. For example, suppose we have a rule which says an expression
+can be the sum of two expressions. When the parser recognizes such a
+sum, each of the subexpressions has a semantic value which describes
+how it was built up. The action for this rule should create a similar
+sort of value for the newly recognized larger expression.
+
+ For example, here is a rule that says an expression can be the sum of
+two subexpressions:
+
+ expr: expr '+' expr { $$ = $1 + $3; }
+ ;
+
+The action says how to produce the semantic value of the sum expression
+from the values of the two subexpressions.

+
+Bison Output: the Parser File
+=============================
+
+ When you run Bison, you give it a Bison grammar file as input. The
+output is a C source file that parses the language described by the
+grammar. This file is called a "Bison parser". Keep in mind that the
+Bison utility and the Bison parser are two distinct programs: the Bison
+utility is a program whose output is the Bison parser that becomes part
+of your program.
+
+ The job of the Bison parser is to group tokens into groupings
+according to the grammar rules--for example, to build identifiers and
+operators into expressions. As it does this, it runs the actions for
+the grammar rules it uses.
+
+ The tokens come from a function called the "lexical analyzer" that
+you must supply in some fashion (such as by writing it in C). The
+Bison parser calls the lexical analyzer each time it wants a new token.
+It doesn't know what is "inside" the tokens (though their semantic
+values may reflect this). Typically the lexical analyzer makes the
+tokens by parsing characters of text, but Bison does not depend on
+this. *Note The Lexical Analyzer Function `yylex': Lexical.
+
+ The Bison parser file is C code which defines a function named
+`yyparse' which implements that grammar. This function does not make a
+complete C program: you must supply some additional functions. One is
+the lexical analyzer. Another is an error-reporting function which the
+parser calls to report an error. In addition, a complete C program must
+start with a function called `main'; you have to provide this, and
+arrange for it to call `yyparse' or the parser will never run. *Note
+Parser C-Language Interface: Interface.
+
+ Aside from the token type names and the symbols in the actions you
+write, all variable and function names used in the Bison parser file
+begin with `yy' or `YY'. This includes interface functions such as the
+lexical analyzer function `yylex', the error reporting function
+`yyerror' and the parser function `yyparse' itself. This also includes
+numerous identifiers used for internal purposes. Therefore, you should
+avoid using C identifiers starting with `yy' or `YY' in the Bison
+grammar file except for the ones defined in this manual.

+
+Stages in Using Bison
+=====================
+
+ The actual language-design process using Bison, from grammar
+specification to a working compiler or interpreter, has these parts:
+
+ 1. Formally specify the grammar in a form recognized by Bison (*note
+ Bison Grammar Files: Grammar File.). For each grammatical rule in
+ the language, describe the action that is to be taken when an
+ instance of that rule is recognized. The action is described by a
+ sequence of C statements.
+
+ 2. Write a lexical analyzer to process input and pass tokens to the
+ parser. The lexical analyzer may be written by hand in C (*note
+ The Lexical Analyzer Function `yylex': Lexical.). It could also
+ be produced using Lex, but the use of Lex is not discussed in this
+ manual.
+
+ 3. Write a controlling function that calls the Bison-produced parser.
+
+ 4. Write error-reporting routines.
+
+ To turn this source code as written into a runnable program, you
+must follow these steps:
+
+ 1. Run Bison on the grammar to produce the parser.
+
+ 2. Compile the code output by Bison, as well as any other source
+ files.
+
+ 3. Link the object files to produce the finished product.
+
+\1f
+File: bison.info, Node: Grammar Layout, Prev: Stages, Up: Concepts
+
+The Overall Layout of a Bison Grammar
+=====================================
+
+ The input file for the Bison utility is a "Bison grammar file". The
+general form of a Bison grammar file is as follows:
+
+ %{
+ C DECLARATIONS
+ %}
+
+ BISON DECLARATIONS
+
+ %%
+ GRAMMAR RULES
+ %%
+ ADDITIONAL C CODE
+
+The `%%', `%{' and `%}' are punctuation that appears in every Bison
+grammar file to separate the sections.
+
+ The C declarations may define types and variables used in the
+actions. You can also use preprocessor commands to define macros used
+there, and use `#include' to include header files that do any of these
+things.
+
+ The Bison declarations declare the names of the terminal and
+nonterminal symbols, and may also describe operator precedence and the
+data types of semantic values of various symbols.
+
+ The grammar rules define how to construct each nonterminal symbol
+from its parts.
+
+ The additional C code can contain any C code you want to use. Often
+the definition of the lexical analyzer `yylex' goes here, plus
+subroutines called by the actions in the grammar rules. In a simple
+program, all the rest of the program can go here.

+This example provides a good starting point, since operator precedence

+Declarations for `rpcalc'
+-------------------------
+
+ Here are the C and Bison declarations for the reverse polish notation
+calculator. As in C, comments are placed between `/*...*/'.
+
+ /* Reverse polish notation calculator. */
+
+ %{
+ #define YYSTYPE double
+ #include <math.h>
+ %}
+
+ %token NUM
+
+ %% /* Grammar rules and actions follow */
+
+ The C declarations section (*note The C Declarations Section: C
+Declarations.) contains two preprocessor directives.
+
+ The `#define' directive defines the macro `YYSTYPE', thus specifying
+the C data type for semantic values of both tokens and groupings (*note
+Data Types of Semantic Values: Value Type.). The Bison parser will use
+whatever type `YYSTYPE' is defined as; if you don't define it, `int' is
+the default. Because we specify `double', each token and each
+expression has an associated value, which is a floating point number.
+
+ The `#include' directive is used to declare the exponentiation
+function `pow'.
+
+ The second section, Bison declarations, provides information to
+Bison about the token types (*note The Bison Declarations Section:
+Bison Declarations.). Each terminal symbol that is not a
+single-character literal must be declared here. (Single-character
+literals normally don't need to be declared.) In this example, all the
+arithmetic operators are designated by single-character literals, so the
+only terminal symbol that needs to be declared is `NUM', the token type
+for numeric constants.

+Grammar Rules for `rpcalc'
+--------------------------
+
+ Here are the grammar rules for the reverse polish notation
+calculator.
+
+ input: /* empty */
+ | input line
+ ;
+
+ line: '\n'
+ | exp '\n' { printf ("\t%.10g\n", $1); }
+ ;
+
+ exp: NUM { $$ = $1; }
+ | exp exp '+' { $$ = $1 + $2; }
+ | exp exp '-' { $$ = $1 - $2; }
+ | exp exp '*' { $$ = $1 * $2; }
+ | exp exp '/' { $$ = $1 / $2; }
+ /* Exponentiation */
+ | exp exp '^' { $$ = pow ($1, $2); }
+ /* Unary minus */
+ | exp 'n' { $$ = -$1; }
+ ;
+ %%
+
+ The groupings of the rpcalc "language" defined here are the
+expression (given the name `exp'), the line of input (`line'), and the
+complete input transcript (`input'). Each of these nonterminal symbols
+has several alternate rules, joined by the `|' punctuator which is read
+as "or". The following sections explain what these rules mean.
+
+ The semantics of the language is determined by the actions taken
+when a grouping is recognized. The actions are the C code that appears
+inside braces. *Note Actions::.
+
+ You must specify these actions in C, but Bison provides the means for
+passing semantic values between the rules. In each action, the
+pseudo-variable `$$' stands for the semantic value for the grouping
+that the rule is going to construct. Assigning a value to `$$' is the
+main job of most actions. The semantic values of the components of the
+rule are referred to as `$1', `$2', and so on.

+File: bison.info, Node: Rpcalc Input, Next: Rpcalc Line, Up: Rpcalc Rules
+
+Explanation of `input'
+......................
+
+ Consider the definition of `input':
+
+ input: /* empty */
+ | input line
+ ;
+
+ This definition reads as follows: "A complete input is either an
+empty string, or a complete input followed by an input line". Notice
+that "complete input" is defined in terms of itself. This definition
+is said to be "left recursive" since `input' appears always as the
+leftmost symbol in the sequence. *Note Recursive Rules: Recursion.
+
+ The first alternative is empty because there are no symbols between
+the colon and the first `|'; this means that `input' can match an empty
+string of input (no tokens). We write the rules this way because it is
+legitimate to type `Ctrl-d' right after you start the calculator. It's
+conventional to put an empty alternative first and write the comment
+`/* empty */' in it.
+
+ The second alternate rule (`input line') handles all nontrivial
+input. It means, "After reading any number of lines, read one more
+line if possible." The left recursion makes this rule into a loop.
+Since the first alternative matches empty input, the loop can be
+executed zero or more times.
+
+ The parser function `yyparse' continues to process input until a
+grammatical error is seen or the lexical analyzer says there are no more
+input tokens; we will arrange for the latter to happen at end of file.
+
+\1f
+File: bison.info, Node: Rpcalc Line, Next: Rpcalc Expr, Prev: Rpcalc Input, Up: Rpcalc Rules
+
+Explanation of `line'
+.....................
+
+ Now consider the definition of `line':
+
+ line: '\n'
+ | exp '\n' { printf ("\t%.10g\n", $1); }
+ ;
+
+ The first alternative is a token which is a newline character; this
+means that rpcalc accepts a blank line (and ignores it, since there is
+no action). The second alternative is an expression followed by a
+newline. This is the alternative that makes rpcalc useful. The
+semantic value of the `exp' grouping is the value of `$1' because the
+`exp' in question is the first symbol in the alternative. The action
+prints this value, which is the result of the computation the user
+asked for.
+
+ This action is unusual because it does not assign a value to `$$'.
+As a consequence, the semantic value associated with the `line' is
+uninitialized (its value will be unpredictable). This would be a bug if
+that value were ever used, but we don't use it: once rpcalc has printed
+the value of the user's input line, that value is no longer needed.
+
+\1f
+File: bison.info, Node: Rpcalc Expr, Prev: Rpcalc Line, Up: Rpcalc Rules
+
+Explanation of `expr'
+.....................
+
+ The `exp' grouping has several rules, one for each kind of
+expression. The first rule handles the simplest expressions: those
+that are just numbers. The second handles an addition-expression,
+which looks like two expressions followed by a plus-sign. The third
+handles subtraction, and so on.
+
+ exp: NUM
+ | exp exp '+' { $$ = $1 + $2; }
+ | exp exp '-' { $$ = $1 - $2; }
+ ...
+ ;
+
+ We have used `|' to join all the rules for `exp', but we could
+equally well have written them separately:
+
+ exp: NUM ;
+ exp: exp exp '+' { $$ = $1 + $2; } ;
+ exp: exp exp '-' { $$ = $1 - $2; } ;
+ ...
+
+ Most of the rules have actions that compute the value of the
+expression in terms of the value of its parts. For example, in the
+rule for addition, `$1' refers to the first component `exp' and `$2'
+refers to the second one. The third component, `'+'', has no meaningful
+associated semantic value, but if it had one you could refer to it as
+`$3'. When `yyparse' recognizes a sum expression using this rule, the
+sum of the two subexpressions' values is produced as the value of the
+entire expression. *Note Actions::.
+
+ You don't have to give an action for every rule. When a rule has no
+action, Bison by default copies the value of `$1' into `$$'. This is
+what happens in the first rule (the one that uses `NUM').
+
+ The formatting shown here is the recommended convention, but Bison
+does not require it. You can add or change whitespace as much as you
+wish. For example, this:
+
+ exp : NUM | exp exp '+' {$$ = $1 + $2; } | ...
+
+means the same thing as this:
+
+ exp: NUM
+ | exp exp '+' { $$ = $1 + $2; }
+ | ...
+
+The latter, however, is much more readable.
+

+File: bison.info, Node: Rpcalc Lexer, Next: Rpcalc Main, Prev: Rpcalc Rules, Up: RPN Calc
+
+The `rpcalc' Lexical Analyzer
+-----------------------------
+
+ The lexical analyzer's job is low-level parsing: converting
+characters or sequences of characters into tokens. The Bison parser
+gets its tokens by calling the lexical analyzer. *Note The Lexical
+Analyzer Function `yylex': Lexical.
+
+ Only a simple lexical analyzer is needed for the RPN calculator.
+This lexical analyzer skips blanks and tabs, then reads in numbers as
+`double' and returns them as `NUM' tokens. Any other character that
+isn't part of a number is a separate token. Note that the token-code
+for such a single-character token is the character itself.
+
+ The return value of the lexical analyzer function is a numeric code
+which represents a token type. The same text used in Bison rules to
+stand for this token type is also a C expression for the numeric code
+for the type. This works in two ways. If the token type is a
+character literal, then its numeric code is the ASCII code for that
+character; you can use the same character literal in the lexical
+analyzer to express the number. If the token type is an identifier,
+that identifier is defined by Bison as a C macro whose definition is
+the appropriate number. In this example, therefore, `NUM' becomes a
+macro for `yylex' to use.
+
+ The semantic value of the token (if it has one) is stored into the
+global variable `yylval', which is where the Bison parser will look for
+it. (The C data type of `yylval' is `YYSTYPE', which was defined at
+the beginning of the grammar; *note Declarations for `rpcalc': Rpcalc
+Decls..)
+
+ A token type code of zero is returned if the end-of-file is
+encountered. (Bison recognizes any nonpositive value as indicating the
+end of the input.)
+
+ Here is the code for the lexical analyzer:
+
+ /* Lexical analyzer returns a double floating point
+ number on the stack and the token NUM, or the ASCII
+ character read if not a number. Skips all blanks
+ and tabs, returns 0 for EOF. */
+
+ #include <ctype.h>
+
+ int
+ yylex (void)
+ {
+ int c;
+
+ /* skip white space */
+ while ((c = getchar ()) == ' ' || c == '\t')
+ ;
+ /* process numbers */
+ if (c == '.' || isdigit (c))
+ {
+ ungetc (c, stdin);
+ scanf ("%lf", &yylval);
+ return NUM;
+ }
+ /* return end-of-file */
+ if (c == EOF)
+ return 0;
+ /* return single chars */
+ return c;
+ }

+
+The Controlling Function
+------------------------
+
+ In keeping with the spirit of this example, the controlling function
+is kept to the bare minimum. The only requirement is that it call
+`yyparse' to start the process of parsing.
+
+ int
+ main (void)
+ {
+ return yyparse ();
+ }
+
+\1f
+File: bison.info, Node: Rpcalc Error, Next: Rpcalc Gen, Prev: Rpcalc Main, Up: RPN Calc
+
+The Error Reporting Routine
+---------------------------
+
+ When `yyparse' detects a syntax error, it calls the error reporting
+function `yyerror' to print an error message (usually but not always
+`"parse error"'). It is up to the programmer to supply `yyerror'
+(*note Parser C-Language Interface: Interface.), so here is the
+definition we will use:
+
+ #include <stdio.h>
+
+ void
+ yyerror (const char *s) /* Called by yyparse on error */
+ {
+ printf ("%s\n", s);
+ }
+
+ After `yyerror' returns, the Bison parser may recover from the error
+and continue parsing if the grammar contains a suitable error rule
+(*note Error Recovery::). Otherwise, `yyparse' returns nonzero. We
+have not written any error rules in this example, so any invalid input
+will cause the calculator program to exit. This is not clean behavior
+for a real calculator, but it is adequate for the first example.
+
+\1f
+File: bison.info, Node: Rpcalc Gen, Next: Rpcalc Compile, Prev: Rpcalc Error, Up: RPN Calc
+
+Running Bison to Make the Parser
+--------------------------------
+
+ Before running Bison to produce a parser, we need to decide how to
+arrange all the source code in one or more source files. For such a
+simple example, the easiest thing is to put everything in one file. The
+definitions of `yylex', `yyerror' and `main' go at the end, in the
+"additional C code" section of the file (*note The Overall Layout of a
+Bison Grammar: Grammar Layout.).
+
+ For a large project, you would probably have several source files,
+and use `make' to arrange to recompile them.
+
+ With all the source in a single file, you use the following command
+to convert it into a parser file:
+
+ bison FILE_NAME.y
+
+In this example the file was called `rpcalc.y' (for "Reverse Polish
+CALCulator"). Bison produces a file named `FILE_NAME.tab.c', removing
+the `.y' from the original file name. The file output by Bison contains
+the source code for `yyparse'. The additional functions in the input
+file (`yylex', `yyerror' and `main') are copied verbatim to the output.
+

+Compiling the Parser File
+-------------------------
+
+ Here is how to compile and run the parser file:

+ # List files in current directory.

+ rpcalc.tab.c rpcalc.y

+ # Compile the Bison parser.

+
+Infix Notation Calculator: `calc'
+=================================
+
+ We now modify rpcalc to handle infix operators instead of postfix.
+Infix notation involves the concept of operator precedence and the need
+for parentheses nested to arbitrary depth. Here is the Bison code for
+`calc.y', an infix desk-top calculator.
+
+ /* Infix notation calculator--calc */
+
+ %{
+ #define YYSTYPE double
+ #include <math.h>
+ %}
+
+ /* BISON Declarations */
+ %token NUM
+ %left '-' '+'
+ %left '*' '/'
+ %left NEG /* negation--unary minus */
+ %right '^' /* exponentiation */
+
+ /* Grammar follows */
+ %%
+ input: /* empty string */
+ | input line
+ ;
+
+ line: '\n'
+ | exp '\n' { printf ("\t%.10g\n", $1); }
+ ;
+
+ exp: NUM { $$ = $1; }
+ | exp '+' exp { $$ = $1 + $3; }
+ | exp '-' exp { $$ = $1 - $3; }
+ | exp '*' exp { $$ = $1 * $3; }
+ | exp '/' exp { $$ = $1 / $3; }
+ | '-' exp %prec NEG { $$ = -$2; }
+ | exp '^' exp { $$ = pow ($1, $3); }
+ | '(' exp ')' { $$ = $2; }
+ ;
+ %%
+
+The functions `yylex', `yyerror' and `main' can be the same as before.
+
+ There are two important new features shown in this code.
+
+ In the second section (Bison declarations), `%left' declares token
+types and says they are left-associative operators. The declarations
+`%left' and `%right' (right associativity) take the place of `%token'
+which is used to declare a token type name without associativity.
+(These tokens are single-character literals, which ordinarily don't
+need to be declared. We declare them here to specify the
+associativity.)
+
+ Operator precedence is determined by the line ordering of the
+declarations; the higher the line number of the declaration (lower on
+the page or screen), the higher the precedence. Hence, exponentiation
+has the highest precedence, unary minus (`NEG') is next, followed by
+`*' and `/', and so on. *Note Operator Precedence: Precedence.
+
+ The other important new feature is the `%prec' in the grammar section
+for the unary minus operator. The `%prec' simply instructs Bison that
+the rule `| '-' exp' has the same precedence as `NEG'--in this case the
+next-to-highest. *Note Context-Dependent Precedence: Contextual

+
+Simple Error Recovery
+=====================
+
+ Up to this point, this manual has not addressed the issue of "error
+recovery"--how to continue parsing after the parser detects a syntax
+error. All we have handled is error reporting with `yyerror'. Recall
+that by default `yyparse' returns after calling `yyerror'. This means
+that an erroneous input line causes the calculator program to exit.
+Now we show how to rectify this deficiency.
+
+ The Bison language itself includes the reserved word `error', which
+may be included in the grammar rules. In the example below it has been
+added to one of the alternatives for `line':
+
+ line: '\n'
+ | exp '\n' { printf ("\t%.10g\n", $1); }
+ | error '\n' { yyerrok; }
+ ;
+
+ This addition to the grammar allows for simple error recovery in the
+event of a parse error. If an expression that cannot be evaluated is
+read, the error will be recognized by the third rule for `line', and
+parsing will continue. (The `yyerror' function is still called upon to
+print its message as well.) The action executes the statement
+`yyerrok', a macro defined automatically by Bison; its meaning is that
+error recovery is complete (*note Error Recovery::). Note the
+difference between `yyerrok' and `yyerror'; neither one is a misprint.
+
+ This form of error recovery deals with syntax errors. There are
+other kinds of errors; for example, division by zero, which raises an
+exception signal that is normally fatal. A real calculator program
+must handle this signal and use `longjmp' to return to `main' and
+resume parsing input lines; it would also have to discard the rest of
+the current line of input. We won't discuss this issue further because
+it is not specific to Bison programs.

+Multi-Function Calculator: `mfcalc'
+===================================
+
+ Now that the basics of Bison have been discussed, it is time to move
+on to a more advanced problem. The above calculators provided only five
+functions, `+', `-', `*', `/' and `^'. It would be nice to have a
+calculator that provides other mathematical functions such as `sin',
+`cos', etc.
+
+ It is easy to add new operators to the infix calculator as long as
+they are only single-character literals. The lexical analyzer `yylex'
+passes back all nonnumber characters as tokens, so new grammar rules
+suffice for adding a new operator. But we want something more
+flexible: built-in functions whose syntax has this form:
+
+ FUNCTION_NAME (ARGUMENT)
+
+At the same time, we will add memory to the calculator, by allowing you
+to create named variables, store values in them, and use them later.
+Here is a sample session with the multi-function calculator:
+
+ % mfcalc
+ pi = 3.141592653589
+ 3.1415926536
+ sin(pi)
+ 0.0000000000
+ alpha = beta1 = 2.3

+Declarations for `mfcalc'
+-------------------------
+
+ Here are the C and Bison declarations for the multi-function
+calculator.
+
+ %{
+ #include <math.h> /* For math functions, cos(), sin(), etc. */
+ #include "calc.h" /* Contains definition of `symrec' */
+ %}
+ %union {
+ double val; /* For returning numbers. */
+ symrec *tptr; /* For returning symbol-table pointers */
+ }
+
+ %token <val> NUM /* Simple double precision number */
+ %token <tptr> VAR FNCT /* Variable and Function */
+ %type <val> exp
+
+ %right '='
+ %left '-' '+'
+ %left '*' '/'
+ %left NEG /* Negation--unary minus */
+ %right '^' /* Exponentiation */
+
+ /* Grammar follows */
+
+ %%
+
+ The above grammar introduces only two new features of the Bison
+language. These features allow semantic values to have various data
+types (*note More Than One Value Type: Multiple Types.).
+
+ The `%union' declaration specifies the entire list of possible types;
+this is instead of defining `YYSTYPE'. The allowable types are now
+double-floats (for `exp' and `NUM') and pointers to entries in the
+symbol table. *Note The Collection of Value Types: Union Decl.
+
+ Since values can now have various types, it is necessary to
+associate a type with each grammar symbol whose semantic value is used.
+These symbols are `NUM', `VAR', `FNCT', and `exp'. Their declarations
+are augmented with information about their data type (placed between
+angle brackets).
+
+ The Bison construct `%type' is used for declaring nonterminal
+symbols, just as `%token' is used for declaring token types. We have
+not used `%type' before because nonterminal symbols are normally
+declared implicitly by the rules that define them. But `exp' must be
+declared explicitly so we can specify its value type. *Note
+Nonterminal Symbols: Type Decl.

+
+The `mfcalc' Symbol Table
+-------------------------
+
+ The multi-function calculator requires a symbol table to keep track
+of the names and meanings of variables and functions. This doesn't
+affect the grammar rules (except for the actions) or the Bison
+declarations, but it requires some additional C functions for support.
+
+ The symbol table itself consists of a linked list of records. Its
+definition, which is kept in the header `calc.h', is as follows. It
+provides for either functions or variables to be placed in the table.
+
+ /* Data type for links in the chain of symbols. */
+ struct symrec
+ {
+ char *name; /* name of symbol */
+ int type; /* type of symbol: either VAR or FNCT */
+ union {
+ double var; /* value of a VAR */
+ double (*fnctptr)(); /* value of a FNCT */
+ } value;
+ struct symrec *next; /* link field */
+ };
+
+ typedef struct symrec symrec;
+
+ /* The symbol table: a chain of `struct symrec'. */
+ extern symrec *sym_table;
+
+ symrec *putsym ();
+ symrec *getsym ();
+
+ The new version of `main' includes a call to `init_table', a
+function that initializes the symbol table. Here it is, and
+`init_table' as well:
+
+ #include <stdio.h>
+
+ int
+ main (void)
+ {
+ init_table ();
+ return yyparse ();
+ }
+
+ void
+ yyerror (const char *s) /* Called by yyparse on error */
+ {
+ printf ("%s\n", s);
+ }
+
+ struct init
+ {
+ char *fname;
+ double (*fnct)();
+ };
+
+ struct init arith_fncts[] =
+ {
+ "sin", sin,
+ "cos", cos,
+ "atan", atan,
+ "ln", log,
+ "exp", exp,
+ "sqrt", sqrt,
+ 0, 0
+ };
+
+ /* The symbol table: a chain of `struct symrec'. */
+ symrec *sym_table = (symrec *)0;
+
+ /* Put arithmetic functions in table. */
+ void
+ init_table (void)
+ {
+ int i;
+ symrec *ptr;
+ for (i = 0; arith_fncts[i].fname != 0; i++)
+ {
+ ptr = putsym (arith_fncts[i].fname, FNCT);
+ ptr->value.fnctptr = arith_fncts[i].fnct;
+ }
+ }
+
+ By simply editing the initialization list and adding the necessary
+include files, you can add additional functions to the calculator.
+
+ Two important functions allow look-up and installation of symbols in
+the symbol table. The function `putsym' is passed a name and the type
+(`VAR' or `FNCT') of the object to be installed. The object is linked
+to the front of the list, and a pointer to the object is returned. The
+function `getsym' is passed the name of the symbol to look up. If
+found, a pointer to that symbol is returned; otherwise zero is returned.
+
+ symrec *
+ putsym (char *sym_name, int sym_type)
+ {
+ symrec *ptr;
+ ptr = (symrec *) malloc (sizeof (symrec));
+ ptr->name = (char *) malloc (strlen (sym_name) + 1);
+ strcpy (ptr->name,sym_name);
+ ptr->type = sym_type;
+ ptr->value.var = 0; /* set value to 0 even if fctn. */
+ ptr->next = (struct symrec *)sym_table;
+ sym_table = ptr;
+ return ptr;
+ }
+
+ symrec *
+ getsym (const char *sym_name)
+ {
+ symrec *ptr;
+ for (ptr = sym_table; ptr != (symrec *) 0;
+ ptr = (symrec *)ptr->next)
+ if (strcmp (ptr->name,sym_name) == 0)
+ return ptr;
+ return 0;
+ }
+
+ The function `yylex' must now recognize variables, numeric values,
+and the single-character arithmetic operators. Strings of alphanumeric
+characters with a leading non-digit are recognized as either variables
+or functions depending on what the symbol table says about them.
+
+ The string is passed to `getsym' for look up in the symbol table. If
+the name appears in the table, a pointer to its location and its type
+(`VAR' or `FNCT') is returned to `yyparse'. If it is not already in
+the table, then it is installed as a `VAR' using `putsym'. Again, a
+pointer and its type (which must be `VAR') is returned to `yyparse'.
+
+ No change is needed in the handling of numeric values and arithmetic
+operators in `yylex'.
+
+ #include <ctype.h>
+
+ int
+ yylex (void)
+ {
+ int c;
+
+ /* Ignore whitespace, get first nonwhite character. */
+ while ((c = getchar ()) == ' ' || c == '\t');
+
+ if (c == EOF)
+ return 0;
+
+ /* Char starts a number => parse the number. */
+ if (c == '.' || isdigit (c))
+ {
+ ungetc (c, stdin);
+ scanf ("%lf", &yylval.val);
+ return NUM;
+ }
+
+ /* Char starts an identifier => read the name. */
+ if (isalpha (c))
+ {
+ symrec *s;
+ static char *symbuf = 0;
+ static int length = 0;
+ int i;
+
+ /* Initially make the buffer long enough
+ for a 40-character symbol name. */
+ if (length == 0)
+ length = 40, symbuf = (char *)malloc (length + 1);
+
+ i = 0;
+ do
+ {
+ /* If buffer is full, make it bigger. */
+ if (i == length)
+ {
+ length *= 2;
+ symbuf = (char *)realloc (symbuf, length + 1);
+ }
+ /* Add this character to the buffer. */
+ symbuf[i++] = c;
+ /* Get another character. */
+ c = getchar ();
+ }
+ while (c != EOF && isalnum (c));
+
+ ungetc (c, stdin);
+ symbuf[i] = '\0';
+
+ s = getsym (symbuf);
+ if (s == 0)
+ s = putsym (symbuf, VAR);
+ yylval.tptr = s;
+ return s->type;
+ }
+
+ /* Any other character is a token by itself. */
+ return c;
+ }
+
+ This program is both powerful and flexible. You may easily add new
+functions, and it is a simple job to modify this code to install
+predefined variables such as `pi' or `e' as well.

+

+File: bison.info, Node: C Declarations, Next: Bison Declarations, Up: Grammar Outline
+
+The C Declarations Section
+--------------------------
+
+ The C DECLARATIONS section contains macro definitions and
+declarations of functions and variables that are used in the actions in
+the grammar rules. These are copied to the beginning of the parser
+file so that they precede the definition of `yyparse'. You can use
+`#include' to get the declarations from a header file. If you don't
+need any C declarations, you may omit the `%{' and `%}' delimiters that
+bracket this section.
+
+\1f
+File: bison.info, Node: Bison Declarations, Next: Grammar Rules, Prev: C Declarations, Up: Grammar Outline
+
+The Bison Declarations Section
+------------------------------
+
+ The BISON DECLARATIONS section contains declarations that define
+terminal and nonterminal symbols, specify precedence, and so on. In
+some simple grammars you may not need any declarations. *Note Bison
+Declarations: Declarations.
+
+\1f
+File: bison.info, Node: Grammar Rules, Next: C Code, Prev: Bison Declarations, Up: Grammar Outline
+
+The Grammar Rules Section
+-------------------------
+
+ The "grammar rules" section contains one or more Bison grammar
+rules, and nothing else. *Note Syntax of Grammar Rules: Rules.
+
+ There must always be at least one grammar rule, and the first `%%'
+(which precedes the grammar rules) may never be omitted even if it is
+the first thing in the file.
+
+\1f
+File: bison.info, Node: C Code, Prev: Grammar Rules, Up: Grammar Outline
+
+The Additional C Code Section
+-----------------------------
+
+ The ADDITIONAL C CODE section is copied verbatim to the end of the
+parser file, just as the C DECLARATIONS section is copied to the
+beginning. This is the most convenient place to put anything that you
+want to have in the parser file but which need not come before the
+definition of `yyparse'. For example, the definitions of `yylex' and
+`yyerror' often go here. *Note Parser C-Language Interface: Interface.
+
+ If the last section is empty, you may omit the `%%' that separates it
+from the grammar rules.
+
+ The Bison parser itself contains many static variables whose names
+start with `yy' and many macros whose names start with `YY'. It is a
+good idea to avoid using any such names (except those documented in this
+manual) in the additional C code section of the grammar file.

+
+Symbols, Terminal and Nonterminal
+=================================
+
+ "Symbols" in Bison grammars represent the grammatical classifications
+of the language.
+
+ A "terminal symbol" (also known as a "token type") represents a
+class of syntactically equivalent tokens. You use the symbol in grammar
+rules to mean that a token in that class is allowed. The symbol is
+represented in the Bison parser by a numeric code, and the `yylex'
+function returns a token type code to indicate what kind of token has
+been read. You don't need to know what the code value is; you can use
+the symbol to stand for it.
+
+ A "nonterminal symbol" stands for a class of syntactically equivalent
+groupings. The symbol name is used in writing grammar rules. By
+convention, it should be all lower case.
+
+ Symbol names can contain letters, digits (not at the beginning),
+underscores and periods. Periods make sense only in nonterminals.
+
+ There are three ways of writing terminal symbols in the grammar:
+
+ * A "named token type" is written with an identifier, like an
+ identifier in C. By convention, it should be all upper case. Each
+ such name must be defined with a Bison declaration such as
+ `%token'. *Note Token Type Names: Token Decl.
+
+ * A "character token type" (or "literal character token") is written
+ in the grammar using the same syntax used in C for character
+ constants; for example, `'+'' is a character token type. A
+ character token type doesn't need to be declared unless you need to
+ specify its semantic value data type (*note Data Types of Semantic
+ Values: Value Type.), associativity, or precedence (*note Operator
+ Precedence: Precedence.).
+
+ By convention, a character token type is used only to represent a
+ token that consists of that particular character. Thus, the token
+ type `'+'' is used to represent the character `+' as a token.
+ Nothing enforces this convention, but if you depart from it, your
+ program will confuse other readers.
+
+ All the usual escape sequences used in character literals in C can
+ be used in Bison as well, but you must not use the null character
+ as a character literal because its ASCII code, zero, is the code
+ `yylex' returns for end-of-input (*note Calling Convention for
+ `yylex': Calling Convention.).
+
+ * A "literal string token" is written like a C string constant; for
+ example, `"<="' is a literal string token. A literal string token
+ doesn't need to be declared unless you need to specify its semantic
+ value data type (*note Value Type::), associativity, or precedence
+ (*note Precedence::).
+
+ You can associate the literal string token with a symbolic name as
+ an alias, using the `%token' declaration (*note Token
+ Declarations: Token Decl.). If you don't do that, the lexical
+ analyzer has to retrieve the token number for the literal string
+ token from the `yytname' table (*note Calling Convention::).
+
+ *WARNING*: literal string tokens do not work in Yacc.
+
+ By convention, a literal string token is used only to represent a
+ token that consists of that particular string. Thus, you should
+ use the token type `"<="' to represent the string `<=' as a token.
+ Bison does not enforce this convention, but if you depart from
+ it, people who read your program will be confused.
+
+ All the escape sequences used in string literals in C can be used
+ in Bison as well. A literal string token must contain two or more
+ characters; for a token containing just one character, use a
+ character token (see above).
+
+ How you choose to write a terminal symbol has no effect on its
+grammatical meaning. That depends only on where it appears in rules and
+on when the parser function returns that symbol.
+
+ The value returned by `yylex' is always one of the terminal symbols
+(or 0 for end-of-input). Whichever way you write the token type in the
+grammar rules, you write it the same way in the definition of `yylex'.
+The numeric code for a character token type is simply the ASCII code for
+the character, so `yylex' can use the identical character constant to
+generate the requisite code. Each named token type becomes a C macro in
+the parser file, so `yylex' can use the name to stand for the code.
+(This is why periods don't make sense in terminal symbols.) *Note
+Calling Convention for `yylex': Calling Convention.
+
+ If `yylex' is defined in a separate file, you need to arrange for the
+token-type macro definitions to be available there. Use the `-d'
+option when you run Bison, so that it will write these macro definitions
+into a separate header file `NAME.tab.h' which you can include in the
+other source files that need it. *Note Invoking Bison: Invocation.
+
+ The symbol `error' is a terminal symbol reserved for error recovery
+(*note Error Recovery::); you shouldn't use it for any other purpose.
+In particular, `yylex' should never return this value.
+
+\1f
+File: bison.info, Node: Rules, Next: Recursion, Prev: Symbols, Up: Grammar File
+
+Syntax of Grammar Rules
+=======================
+
+ A Bison grammar rule has the following general form:
+
+ RESULT: COMPONENTS...
+ ;
+
+where RESULT is the nonterminal symbol that this rule describes, and
+COMPONENTS are various terminal and nonterminal symbols that are put
+together by this rule (*note Symbols::).
+
+ For example,
+
+ exp: exp '+' exp
+ ;
+
+says that two groupings of type `exp', with a `+' token in between, can
+be combined into a larger grouping of type `exp'.
+
+ Whitespace in rules is significant only to separate symbols. You
+can add extra whitespace as you wish.
+
+ Scattered among the components can be ACTIONS that determine the
+semantics of the rule. An action looks like this:
+
+ {C STATEMENTS}
+
+Usually there is only one action and it follows the components. *Note
+Actions::.
+
+ Multiple rules for the same RESULT can be written separately or can
+be joined with the vertical-bar character `|' as follows:
+
+ RESULT: RULE1-COMPONENTS...
+ | RULE2-COMPONENTS...
+ ...
+ ;
+
+They are still considered distinct rules even when joined in this way.
+
+ If COMPONENTS in a rule is empty, it means that RESULT can match the
+empty string. For example, here is how to define a comma-separated
+sequence of zero or more `exp' groupings:
+
+ expseq: /* empty */
+ | expseq1
+ ;
+
+ expseq1: exp
+ | expseq1 ',' exp
+ ;
+
+It is customary to write a comment `/* empty */' in each rule with no
+components.
+
+\1f
+File: bison.info, Node: Recursion, Next: Semantics, Prev: Rules, Up: Grammar File
+
+Recursive Rules
+===============
+
+ A rule is called "recursive" when its RESULT nonterminal appears
+also on its right hand side. Nearly all Bison grammars need to use
+recursion, because that is the only way to define a sequence of any
+number of a particular thing. Consider this recursive definition of a
+comma-separated sequence of one or more expressions:
+
+ expseq1: exp
+ | expseq1 ',' exp
+ ;
+
+Since the recursive use of `expseq1' is the leftmost symbol in the
+right hand side, we call this "left recursion". By contrast, here the
+same construct is defined using "right recursion":
+
+ expseq1: exp
+ | exp ',' expseq1
+ ;
+
+Any kind of sequence can be defined using either left recursion or
+right recursion, but you should always use left recursion, because it
+can parse a sequence of any number of elements with bounded stack
+space. Right recursion uses up space on the Bison stack in proportion
+to the number of elements in the sequence, because all the elements
+must be shifted onto the stack before the rule can be applied even
+once. *Note The Bison Parser Algorithm: Algorithm, for further
+explanation of this.
+
+ "Indirect" or "mutual" recursion occurs when the result of the rule
+does not appear directly on its right hand side, but does appear in
+rules for other nonterminals which do appear on its right hand side.
+
+ For example:
+
+ expr: primary
+ | primary '+' primary
+ ;
+
+ primary: constant
+ | '(' expr ')'
+ ;
+
+defines two mutually-recursive nonterminals, since each refers to the
+other.
+

+File: bison.info, Node: Semantics, Next: Declarations, Prev: Recursion, Up: Grammar File
+
+Defining Language Semantics
+===========================
+
+ The grammar rules for a language determine only the syntax. The
+semantics are determined by the semantic values associated with various
+tokens and groupings, and by the actions taken when various groupings
+are recognized.
+
+ For example, the calculator calculates properly because the value
+associated with each expression is the proper number; it adds properly
+because the action for the grouping `X + Y' is to add the numbers
+associated with X and Y.
+
+* Menu:
+
+* Value Type:: Specifying one data type for all semantic values.
+* Multiple Types:: Specifying several alternative data types.
+* Actions:: An action is the semantic definition of a grammar rule.
+* Action Types:: Specifying data types for actions to operate on.
+* Mid-Rule Actions:: Most actions go at the end of a rule.
+ This says when, why and how to use the exceptional
+ action in the middle of a rule.

+
+Data Types of Semantic Values
+-----------------------------
+
+ In a simple program it may be sufficient to use the same data type
+for the semantic values of all language constructs. This was true in
+the RPN and infix calculator examples (*note Reverse Polish Notation
+Calculator: RPN Calc.).
+
+ Bison's default is to use type `int' for all semantic values. To
+specify some other type, define `YYSTYPE' as a macro, like this:
+
+ #define YYSTYPE double
+
+This macro definition must go in the C declarations section of the
+grammar file (*note Outline of a Bison Grammar: Grammar Outline.).

+
+More Than One Value Type
+------------------------
+
+ In most programs, you will need different data types for different
+kinds of tokens and groupings. For example, a numeric constant may
+need type `int' or `long', while a string constant needs type `char *',
+and an identifier might need a pointer to an entry in the symbol table.
+
+ To use more than one data type for semantic values in one parser,
+Bison requires you to do two things:
+
+ * Specify the entire collection of possible data types, with the
+ `%union' Bison declaration (*note The Collection of Value Types:
+ Union Decl.).
+
+ * Choose one of those types for each symbol (terminal or
+ nonterminal) for which semantic values are used. This is done for
+ tokens with the `%token' Bison declaration (*note Token Type
+ Names: Token Decl.) and for groupings with the `%type' Bison
+ declaration (*note Nonterminal Symbols: Type Decl.).
+
+\1f
+File: bison.info, Node: Actions, Next: Action Types, Prev: Multiple Types, Up: Semantics
+
+Actions
+-------
+
+ An action accompanies a syntactic rule and contains C code to be
+executed each time an instance of that rule is recognized. The task of
+most actions is to compute a semantic value for the grouping built by
+the rule from the semantic values associated with tokens or smaller
+groupings.
+
+ An action consists of C statements surrounded by braces, much like a
+compound statement in C. It can be placed at any position in the rule;
+it is executed at that position. Most rules have just one action at
+the end of the rule, following all the components. Actions in the
+middle of a rule are tricky and used only for special purposes (*note
+Actions in Mid-Rule: Mid-Rule Actions.).
+
+ The C code in an action can refer to the semantic values of the
+components matched by the rule with the construct `$N', which stands for
+the value of the Nth component. The semantic value for the grouping
+being constructed is `$$'. (Bison translates both of these constructs
+into array element references when it copies the actions into the parser
+file.)
+
+ Here is a typical example:
+
+ exp: ...
+ | exp '+' exp
+ { $$ = $1 + $3; }
+
+This rule constructs an `exp' from two smaller `exp' groupings
+connected by a plus-sign token. In the action, `$1' and `$3' refer to
+the semantic values of the two component `exp' groupings, which are the
+first and third symbols on the right hand side of the rule. The sum is
+stored into `$$' so that it becomes the semantic value of the
+addition-expression just recognized by the rule. If there were a
+useful semantic value associated with the `+' token, it could be
+referred to as `$2'.
+
+ If you don't specify an action for a rule, Bison supplies a default:
+`$$ = $1'. Thus, the value of the first symbol in the rule becomes the
+value of the whole rule. Of course, the default rule is valid only if
+the two data types match. There is no meaningful default action for an
+empty rule; every empty rule must have an explicit action unless the
+rule's value does not matter.
+
+ `$N' with N zero or negative is allowed for reference to tokens and
+groupings on the stack _before_ those that match the current rule.
+This is a very risky practice, and to use it reliably you must be
+certain of the context in which the rule is applied. Here is a case in
+which you can use this reliably:
+
+ foo: expr bar '+' expr { ... }
+ | expr bar '-' expr { ... }
+ ;
+
+ bar: /* empty */
+ { previous_expr = $0; }
+ ;
+
+ As long as `bar' is used only in the fashion shown here, `$0' always
+refers to the `expr' which precedes `bar' in the definition of `foo'.
+
+\1f
+File: bison.info, Node: Action Types, Next: Mid-Rule Actions, Prev: Actions, Up: Semantics
+
+Data Types of Values in Actions
+-------------------------------
+
+ If you have chosen a single data type for semantic values, the `$$'
+and `$N' constructs always have that data type.
+
+ If you have used `%union' to specify a variety of data types, then
+you must declare a choice among these types for each terminal or
+nonterminal symbol that can have a semantic value. Then each time you
+use `$$' or `$N', its data type is determined by which symbol it refers
+to in the rule. In this example,
+
+ exp: ...
+ | exp '+' exp
+ { $$ = $1 + $3; }
+
+`$1' and `$3' refer to instances of `exp', so they all have the data
+type declared for the nonterminal symbol `exp'. If `$2' were used, it
+would have the data type declared for the terminal symbol `'+'',
+whatever that might be.
+
+ Alternatively, you can specify the data type when you refer to the
+value, by inserting `<TYPE>' after the `$' at the beginning of the
+reference. For example, if you have defined types as shown here:
+
+ %union {
+ int itype;
+ double dtype;
+ }
+
+then you can write `$<itype>1' to refer to the first subunit of the
+rule as an integer, or `$<dtype>1' to refer to it as a double.

+
+Actions in Mid-Rule
+-------------------
+
+ Occasionally it is useful to put an action in the middle of a rule.
+These actions are written just like usual end-of-rule actions, but they
+are executed before the parser even recognizes the following components.
+
+ A mid-rule action may refer to the components preceding it using
+`$N', but it may not refer to subsequent components because it is run
+before they are parsed.
+
+ The mid-rule action itself counts as one of the components of the
+rule. This makes a difference when there is another action later in
+the same rule (and usually there is another at the end): you have to
+count the actions along with the symbols when working out which number
+N to use in `$N'.
+
+ The mid-rule action can also have a semantic value. The action can
+set its value with an assignment to `$$', and actions later in the rule
+can refer to the value using `$N'. Since there is no symbol to name
+the action, there is no way to declare a data type for the value in
+advance, so you must use the `$<...>' construct to specify a data type
+each time you refer to this value.
+
+ There is no way to set the value of the entire rule with a mid-rule
+action, because assignments to `$$' do not have that effect. The only
+way to set the value for the entire rule is with an ordinary action at
+the end of the rule.
+
+ Here is an example from a hypothetical compiler, handling a `let'
+statement that looks like `let (VARIABLE) STATEMENT' and serves to
+create a variable named VARIABLE temporarily for the duration of
+STATEMENT. To parse this construct, we must put VARIABLE into the
+symbol table while STATEMENT is parsed, then remove it afterward. Here
+is how it is done:
+
+ stmt: LET '(' var ')'
+ { $<context>$ = push_context ();
+ declare_variable ($3); }
+ stmt { $$ = $6;
+ pop_context ($<context>5); }
+
+As soon as `let (VARIABLE)' has been recognized, the first action is
+run. It saves a copy of the current semantic context (the list of
+accessible variables) as its semantic value, using alternative
+`context' in the data-type union. Then it calls `declare_variable' to
+add the new variable to that list. Once the first action is finished,
+the embedded statement `stmt' can be parsed. Note that the mid-rule
+action is component number 5, so the `stmt' is component number 6.
+
+ After the embedded statement is parsed, its semantic value becomes
+the value of the entire `let'-statement. Then the semantic value from
+the earlier action is used to restore the prior list of variables. This
+removes the temporary `let'-variable from the list so that it won't
+appear to exist while the rest of the program is parsed.
+
+ Taking action before a rule is completely recognized often leads to
+conflicts since the parser must commit to a parse in order to execute
+the action. For example, the following two rules, without mid-rule
+actions, can coexist in a working parser because the parser can shift
+the open-brace token and look at what follows before deciding whether
+there is a declaration or not:
+
+ compound: '{' declarations statements '}'
+ | '{' statements '}'
+ ;
+
+But when we add a mid-rule action as follows, the rules become
+nonfunctional:
+
+ compound: { prepare_for_local_variables (); }
+ '{' declarations statements '}'
+ | '{' statements '}'
+ ;
+
+Now the parser is forced to decide whether to run the mid-rule action
+when it has read no farther than the open-brace. In other words, it
+must commit to using one rule or the other, without sufficient
+information to do it correctly. (The open-brace token is what is called
+the "look-ahead" token at this time, since the parser is still deciding
+what to do about it. *Note Look-Ahead Tokens: Look-Ahead.)
+
+ You might think that you could correct the problem by putting
+identical actions into the two rules, like this:
+
+ compound: { prepare_for_local_variables (); }
+ '{' declarations statements '}'
+ | { prepare_for_local_variables (); }
+ '{' statements '}'
+ ;
+
+But this does not help, because Bison does not realize that the two
+actions are identical. (Bison never tries to understand the C code in
+an action.)
+
+ If the grammar is such that a declaration can be distinguished from a
+statement by the first token (which is true in C), then one solution
+which does work is to put the action after the open-brace, like this:
+
+ compound: '{' { prepare_for_local_variables (); }
+ declarations statements '}'
+ | '{' statements '}'
+ ;
+
+Now the first token of the following declaration or statement, which
+would in any case tell Bison which rule to use, can still do so.
+
+ Another solution is to bury the action inside a nonterminal symbol
+which serves as a subroutine:
+
+ subroutine: /* empty */
+ { prepare_for_local_variables (); }
+ ;
+
+ compound: subroutine
+ '{' declarations statements '}'
+ | subroutine
+ '{' statements '}'
+ ;
+
+Now Bison can execute the action in the rule for `subroutine' without
+deciding which rule for `compound' it will eventually use. Note that
+the action is now at the end of its rule. Any mid-rule action can be
+converted to an end-of-rule action in this way, and this is what Bison
+actually does to implement mid-rule actions.

+Bison Declarations
+==================
+
+ The "Bison declarations" section of a Bison grammar defines the
+symbols used in formulating the grammar and the data types of semantic
+values. *Note Symbols::.
+
+ All token type names (but not single-character literal tokens such as
+`'+'' and `'*'') must be declared. Nonterminal symbols must be
+declared if you need to specify which data type to use for the semantic
+value (*note More Than One Value Type: Multiple Types.).
+
+ The first rule in the file also specifies the start symbol, by
+default. If you want some other symbol to be the start symbol, you
+must declare it explicitly (*note Languages and Context-Free Grammars:
+Language and Grammar.).
+
+* Menu:
+
+* Token Decl:: Declaring terminal symbols.
+* Precedence Decl:: Declaring terminals with precedence and associativity.
+* Union Decl:: Declaring the set of all semantic value types.
+* Type Decl:: Declaring the choice of type for a nonterminal symbol.
+* Expect Decl:: Suppressing warnings about shift/reduce conflicts.
+* Start Decl:: Specifying the start symbol.
+* Pure Decl:: Requesting a reentrant parser.
+* Decl Summary:: Table of all Bison declarations.
+
+\1f
+File: bison.info, Node: Token Decl, Next: Precedence Decl, Up: Declarations
+
+Token Type Names
+----------------
+
+ The basic way to declare a token type name (terminal symbol) is as
+follows:
+
+ %token NAME
+
+ Bison will convert this into a `#define' directive in the parser, so
+that the function `yylex' (if it is in this file) can use the name NAME
+to stand for this token type's code.
+
+ Alternatively, you can use `%left', `%right', or `%nonassoc' instead
+of `%token', if you wish to specify associativity and precedence.
+*Note Operator Precedence: Precedence Decl.
+
+ You can explicitly specify the numeric code for a token type by
+appending an integer value in the field immediately following the token
+name:
+
+ %token NUM 300
+
+It is generally best, however, to let Bison choose the numeric codes for
+all token types. Bison will automatically select codes that don't
+conflict with each other or with ASCII characters.
+
+ In the event that the stack type is a union, you must augment the
+`%token' or other token declaration to include the data type
+alternative delimited by angle-brackets (*note More Than One Value
+Type: Multiple Types.).
+
+ For example:
+
+ %union { /* define stack type */
+ double val;
+ symrec *tptr;
+ }
+ %token <val> NUM /* define token NUM and its type */
+
+ You can associate a literal string token with a token type name by
+writing the literal string at the end of a `%token' declaration which
+declares the name. For example:
+
+ %token arrow "=>"
+
+For example, a grammar for the C language might specify these names with
+equivalent literal string tokens:
+
+ %token <operator> OR "||"
+ %token <operator> LE 134 "<="
+ %left OR "<="
+
+Once you equate the literal string and the token name, you can use them
+interchangeably in further declarations or the grammar rules. The
+`yylex' function can use the token name or the literal string to obtain
+the token type code number (*note Calling Convention::).
+
+\1f
+File: bison.info, Node: Precedence Decl, Next: Union Decl, Prev: Token Decl, Up: Declarations
+
+Operator Precedence
+-------------------
+
+ Use the `%left', `%right' or `%nonassoc' declaration to declare a
+token and specify its precedence and associativity, all at once. These
+are called "precedence declarations". *Note Operator Precedence:
+Precedence, for general information on operator precedence.
+
+ The syntax of a precedence declaration is the same as that of
+`%token': either
+
+ %left SYMBOLS...
+
+or
+
+ %left <TYPE> SYMBOLS...
+
+ And indeed any of these declarations serves the purposes of `%token'.
+But in addition, they specify the associativity and relative precedence
+for all the SYMBOLS:
+
+ * The associativity of an operator OP determines how repeated uses
+ of the operator nest: whether `X OP Y OP Z' is parsed by grouping
+ X with Y first or by grouping Y with Z first. `%left' specifies
+ left-associativity (grouping X with Y first) and `%right'
+ specifies right-associativity (grouping Y with Z first).
+ `%nonassoc' specifies no associativity, which means that `X OP Y
+ OP Z' is considered a syntax error.
+
+ * The precedence of an operator determines how it nests with other
+ operators. All the tokens declared in a single precedence
+ declaration have equal precedence and nest together according to
+ their associativity. When two tokens declared in different
+ precedence declarations associate, the one declared later has the
+ higher precedence and is grouped first.
+
+\1f
+File: bison.info, Node: Union Decl, Next: Type Decl, Prev: Precedence Decl, Up: Declarations
+
+The Collection of Value Types
+-----------------------------
+
+ The `%union' declaration specifies the entire collection of possible
+data types for semantic values. The keyword `%union' is followed by a
+pair of braces containing the same thing that goes inside a `union' in
+C.
+
+ For example:
+
+ %union {
+ double val;
+ symrec *tptr;
+ }
+
+This says that the two alternative types are `double' and `symrec *'.
+They are given names `val' and `tptr'; these names are used in the
+`%token' and `%type' declarations to pick one of the types for a
+terminal or nonterminal symbol (*note Nonterminal Symbols: Type Decl.).
+
+ Note that, unlike making a `union' declaration in C, you do not write
+a semicolon after the closing brace.
+
+\1f
+File: bison.info, Node: Type Decl, Next: Expect Decl, Prev: Union Decl, Up: Declarations
+
+Nonterminal Symbols
+-------------------
+
+When you use `%union' to specify multiple value types, you must declare
+the value type of each nonterminal symbol for which values are used.
+This is done with a `%type' declaration, like this:
+
+ %type <TYPE> NONTERMINAL...
+
+Here NONTERMINAL is the name of a nonterminal symbol, and TYPE is the
+name given in the `%union' to the alternative that you want (*note The
+Collection of Value Types: Union Decl.). You can give any number of
+nonterminal symbols in the same `%type' declaration, if they have the
+same value type. Use spaces to separate the symbol names.
+
+ You can also declare the value type of a terminal symbol. To do
+this, use the same `<TYPE>' construction in a declaration for the
+terminal symbol. All kinds of token declarations allow `<TYPE>'.
+
+\1f
+File: bison.info, Node: Expect Decl, Next: Start Decl, Prev: Type Decl, Up: Declarations
+
+Suppressing Conflict Warnings
+-----------------------------
+
+ Bison normally warns if there are any conflicts in the grammar
+(*note Shift/Reduce Conflicts: Shift/Reduce.), but most real grammars
+have harmless shift/reduce conflicts which are resolved in a
+predictable way and would be difficult to eliminate. It is desirable
+to suppress the warning about these conflicts unless the number of
+conflicts changes. You can do this with the `%expect' declaration.
+
+ The declaration looks like this:
+
+ %expect N
+
+ Here N is a decimal integer. The declaration says there should be no
+warning if there are N shift/reduce conflicts and no reduce/reduce
+conflicts. The usual warning is given if there are either more or fewer
+conflicts, or if there are any reduce/reduce conflicts.
+
+ In general, using `%expect' involves these steps:
+
+ * Compile your grammar without `%expect'. Use the `-v' option to
+ get a verbose list of where the conflicts occur. Bison will also
+ print the number of conflicts.
+
+ * Check each of the conflicts to make sure that Bison's default
+ resolution is what you really want. If not, rewrite the grammar
+ and go back to the beginning.
+
+ * Add an `%expect' declaration, copying the number N from the number
+ which Bison printed.
+
+ Now Bison will stop annoying you about the conflicts you have
+checked, but it will warn you again if changes in the grammar result in
+additional conflicts.
+
+\1f
+File: bison.info, Node: Start Decl, Next: Pure Decl, Prev: Expect Decl, Up: Declarations
+
+The Start-Symbol
+----------------
+
+ Bison assumes by default that the start symbol for the grammar is
+the first nonterminal specified in the grammar specification section.
+The programmer may override this restriction with the `%start'
+declaration as follows:
+
+ %start SYMBOL
+
+\1f
+File: bison.info, Node: Pure Decl, Next: Decl Summary, Prev: Start Decl, Up: Declarations
+
+A Pure (Reentrant) Parser
+-------------------------
+
+ A "reentrant" program is one which does not alter in the course of
+execution; in other words, it consists entirely of "pure" (read-only)
+code. Reentrancy is important whenever asynchronous execution is
+possible; for example, a non-reentrant program may not be safe to call
+from a signal handler. In systems with multiple threads of control, a
+non-reentrant program must be called only within interlocks.
+
+ Normally, Bison generates a parser which is not reentrant. This is
+suitable for most uses, and it permits compatibility with YACC. (The
+standard YACC interfaces are inherently nonreentrant, because they use
+statically allocated variables for communication with `yylex',
+including `yylval' and `yylloc'.)
+
+ Alternatively, you can generate a pure, reentrant parser. The Bison
+declaration `%pure_parser' says that you want the parser to be
+reentrant. It looks like this:
+
+ %pure_parser
+
+ The result is that the communication variables `yylval' and `yylloc'
+become local variables in `yyparse', and a different calling convention
+is used for the lexical analyzer function `yylex'. *Note Calling
+Conventions for Pure Parsers: Pure Calling, for the details of this.
+The variable `yynerrs' also becomes local in `yyparse' (*note The Error
+Reporting Function `yyerror': Error Reporting.). The convention for
+calling `yyparse' itself is unchanged.
+
+ Whether the parser is pure has nothing to do with the grammar rules.
+You can generate either a pure parser or a nonreentrant parser from any
+valid grammar.
+
+\1f
+File: bison.info, Node: Decl Summary, Prev: Pure Decl, Up: Declarations
+
+Bison Declaration Summary
+-------------------------
+
+ Here is a summary of all Bison declarations:
+
+`%union'
+ Declare the collection of data types that semantic values may have
+ (*note The Collection of Value Types: Union Decl.).
+
+`%token'
+ Declare a terminal symbol (token type name) with no precedence or
+ associativity specified (*note Token Type Names: Token Decl.).
+
+`%right'
+ Declare a terminal symbol (token type name) that is
+ right-associative (*note Operator Precedence: Precedence Decl.).
+
+`%left'
+ Declare a terminal symbol (token type name) that is
+ left-associative (*note Operator Precedence: Precedence Decl.).
+
+`%nonassoc'
+ Declare a terminal symbol (token type name) that is nonassociative
+ (using it in a way that would be associative is a syntax error)
+ (*note Operator Precedence: Precedence Decl.).
+
+`%type'
+ Declare the type of semantic values for a nonterminal symbol
+ (*note Nonterminal Symbols: Type Decl.).
+
+`%start'
+ Specify the grammar's start symbol (*note The Start-Symbol: Start
+ Decl.).
+
+`%expect'
+ Declare the expected number of shift-reduce conflicts (*note
+ Suppressing Conflict Warnings: Expect Decl.).
+
+`%locations'
+ Generate the code processing the locations (*note Special Features
+ for Use in Actions: Action Features.). This mode is enabled as
+ soon as the grammar uses the special `@N' tokens, but if your
+ grammar does not use it, using `%locations' allows for more
+ accurate parse error messages.
+
+`%pure_parser'
+ Request a pure (reentrant) parser program (*note A Pure
+ (Reentrant) Parser: Pure Decl.).
+
+`%no_lines'
+ Don't generate any `#line' preprocessor commands in the parser
+ file. Ordinarily Bison writes these commands in the parser file
+ so that the C compiler and debuggers will associate errors and
+ object code with your source file (the grammar file). This
+ directive causes them to associate errors with the parser file,
+ treating it an independent source file in its own right.
+
+`%raw'
+ The output file `NAME.h' normally defines the tokens with
+ Yacc-compatible token numbers. If this option is specified, the
+ internal Bison numbers are used instead. (Yacc-compatible numbers
+ start at 257 except for single-character tokens; Bison assigns
+ token numbers sequentially for all tokens starting at 3.)
+
+`%token_table'
+ Generate an array of token names in the parser file. The name of
+ the array is `yytname'; `yytname[I]' is the name of the token
+ whose internal Bison token code number is I. The first three
+ elements of `yytname' are always `"$"', `"error"', and
+ `"$illegal"'; after these come the symbols defined in the grammar
+ file.
+
+ For single-character literal tokens and literal string tokens, the
+ name in the table includes the single-quote or double-quote
+ characters: for example, `"'+'"' is a single-character literal and
+ `"\"<=\""' is a literal string token. All the characters of the
+ literal string token appear verbatim in the string found in the
+ table; even double-quote characters are not escaped. For example,
+ if the token consists of three characters `*"*', its string in
+ `yytname' contains `"*"*"'. (In C, that would be written as
+ `"\"*\"*\""').
+
+ When you specify `%token_table', Bison also generates macro
+ definitions for macros `YYNTOKENS', `YYNNTS', and `YYNRULES', and
+ `YYNSTATES':
+
+ `YYNTOKENS'
+ The highest token number, plus one.
+
+ `YYNNTS'
+ The number of nonterminal symbols.
+
+ `YYNRULES'
+ The number of grammar rules,
+
+ `YYNSTATES'
+ The number of parser states (*note Parser States::).

+
+Multiple Parsers in the Same Program
+====================================
+
+ Most programs that use Bison parse only one language and therefore
+contain only one Bison parser. But what if you want to parse more than
+one language with the same program? Then you need to avoid a name
+conflict between different definitions of `yyparse', `yylval', and so
+on.
+
+ The easy way to do this is to use the option `-p PREFIX' (*note
+Invoking Bison: Invocation.). This renames the interface functions and
+variables of the Bison parser to start with PREFIX instead of `yy'.
+You can use this to give each parser distinct names that do not
+conflict.
+
+ The precise list of symbols renamed is `yyparse', `yylex',
+`yyerror', `yynerrs', `yylval', `yychar' and `yydebug'. For example,
+if you use `-p c', the names become `cparse', `clex', and so on.
+
+ *All the other variables and macros associated with Bison are not
+renamed.* These others are not global; there is no conflict if the same
+name is used in different parsers. For example, `YYSTYPE' is not
+renamed, but defining this in different ways in different parsers causes
+no trouble (*note Data Types of Semantic Values: Value Type.).
+
+ The `-p' option works by adding macro definitions to the beginning
+of the parser source file, defining `yyparse' as `PREFIXparse', and so
+on. This effectively substitutes one name for the other in the entire
+parser file.

+ You call the function `yyparse' to cause parsing to occur. This
+function reads tokens, executes actions, and ultimately returns when it
+encounters end-of-input or an unrecoverable syntax error. You can also
+write an action which directs `yyparse' to return immediately without
+reading further.
+
+ The value returned by `yyparse' is 0 if parsing was successful
+(return is due to end-of-input).
+
+ The value is 1 if parsing failed (return is due to a syntax error).
+
+ In an action, you can cause immediate return from `yyparse' by using
+these macros:
+
+`YYACCEPT'
+ Return immediately with value 0 (to report success).
+
+`YYABORT'
+ Return immediately with value 1 (to report failure).

+
+The Lexical Analyzer Function `yylex'
+=====================================
+
+ The "lexical analyzer" function, `yylex', recognizes tokens from the
+input stream and returns them to the parser. Bison does not create
+this function automatically; you must write it so that `yyparse' can
+call it. The function is sometimes referred to as a lexical scanner.
+
+ In simple programs, `yylex' is often defined at the end of the Bison
+grammar file. If `yylex' is defined in a separate source file, you
+need to arrange for the token-type macro definitions to be available
+there. To do this, use the `-d' option when you run Bison, so that it
+will write these macro definitions into a separate header file
+`NAME.tab.h' which you can include in the other source files that need
+it. *Note Invoking Bison: Invocation.
+

+
+* Calling Convention:: How `yyparse' calls `yylex'.
+* Token Values:: How `yylex' must return the semantic value
+ of the token it has read.
+* Token Positions:: How `yylex' must return the text position

+ in a pure parser (*note A Pure (Reentrant) Parser: Pure Decl.).
+
+\1f
+File: bison.info, Node: Calling Convention, Next: Token Values, Up: Lexical
+
+Calling Convention for `yylex'
+------------------------------
+
+ The value that `yylex' returns must be the numeric code for the type
+of token it has just found, or 0 for end-of-input.
+
+ When a token is referred to in the grammar rules by a name, that name
+in the parser file becomes a C macro whose definition is the proper
+numeric code for that token type. So `yylex' can use the name to
+indicate that type. *Note Symbols::.
+
+ When a token is referred to in the grammar rules by a character
+literal, the numeric code for that character is also the code for the
+token type. So `yylex' can simply return that character code. The
+null character must not be used this way, because its code is zero and
+that is what signifies end-of-input.
+
+ Here is an example showing these things:
+
+ int
+ yylex (void)
+ {
+ ...
+ if (c == EOF) /* Detect end of file. */
+ return 0;
+ ...
+ if (c == '+' || c == '-')
+ return c; /* Assume token type for `+' is '+'. */
+ ...
+ return INT; /* Return the type of the token. */
+ ...
+ }
+
+This interface has been designed so that the output from the `lex'
+utility can be used without change as the definition of `yylex'.
+
+ If the grammar uses literal string tokens, there are two ways that
+`yylex' can determine the token type codes for them:
+
+ * If the grammar defines symbolic token names as aliases for the
+ literal string tokens, `yylex' can use these symbolic names like
+ all others. In this case, the use of the literal string tokens in
+ the grammar file has no effect on `yylex'.
+
+ * `yylex' can find the multicharacter token in the `yytname' table.
+ The index of the token in the table is the token type's code. The
+ name of a multicharacter token is recorded in `yytname' with a
+ double-quote, the token's characters, and another double-quote.
+ The token's characters are not escaped in any way; they appear
+ verbatim in the contents of the string in the table.
+
+ Here's code for looking up a token in `yytname', assuming that the
+ characters of the token are stored in `token_buffer'.
+
+ for (i = 0; i < YYNTOKENS; i++)
+ {
+ if (yytname[i] != 0
+ && yytname[i][0] == '"'
+ && strncmp (yytname[i] + 1, token_buffer,
+ strlen (token_buffer))
+ && yytname[i][strlen (token_buffer) + 1] == '"'
+ && yytname[i][strlen (token_buffer) + 2] == 0)
+ break;
+ }
+
+ The `yytname' table is generated only if you use the
+ `%token_table' declaration. *Note Decl Summary::.

+
+Semantic Values of Tokens
+-------------------------
+
+ In an ordinary (non-reentrant) parser, the semantic value of the
+token must be stored into the global variable `yylval'. When you are
+using just one data type for semantic values, `yylval' has that type.
+Thus, if the type is `int' (the default), you might write this in
+`yylex':
+
+ ...
+ yylval = value; /* Put value onto Bison stack. */
+ return INT; /* Return the type of the token. */
+ ...
+
+ When you are using multiple data types, `yylval''s type is a union
+made from the `%union' declaration (*note The Collection of Value
+Types: Union Decl.). So when you store a token's value, you must use
+the proper member of the union. If the `%union' declaration looks like
+this:
+
+ %union {
+ int intval;
+ double val;
+ symrec *tptr;
+ }
+
+then the code in `yylex' might look like this:
+
+ ...
+ yylval.intval = value; /* Put value onto Bison stack. */
+ return INT; /* Return the type of the token. */
+ ...
+

+
+Textual Positions of Tokens
+---------------------------
+
+ If you are using the `@N'-feature (*note Special Features for Use in
+Actions: Action Features.) in actions to keep track of the textual
+locations of tokens and groupings, then you must provide this
+information in `yylex'. The function `yyparse' expects to find the
+textual location of a token just parsed in the global variable
+`yylloc'. So `yylex' must store the proper data in that variable. The
+value of `yylloc' is a structure and you need only initialize the
+members that are going to be used by the actions. The four members are
+called `first_line', `first_column', `last_line' and `last_column'.
+Note that the use of this feature makes the parser noticeably slower.
+
+ The data type of `yylloc' has the name `YYLTYPE'.
+
+\1f
+File: bison.info, Node: Pure Calling, Prev: Token Positions, Up: Lexical
+
+Calling Conventions for Pure Parsers
+------------------------------------
+
+ When you use the Bison declaration `%pure_parser' to request a pure,
+reentrant parser, the global communication variables `yylval' and
+`yylloc' cannot be used. (*Note A Pure (Reentrant) Parser: Pure Decl.)
+In such parsers the two global variables are replaced by pointers
+passed as arguments to `yylex'. You must declare them as shown here,
+and pass the information back by storing it through those pointers.
+
+ int
+ yylex (YYSTYPE *lvalp, YYLTYPE *llocp)
+ {
+ ...
+ *lvalp = value; /* Put value onto Bison stack. */
+ return INT; /* Return the type of the token. */
+ ...
+ }
+
+ If the grammar file does not use the `@' constructs to refer to
+textual positions, then the type `YYLTYPE' will not be defined. In
+this case, omit the second argument; `yylex' will be called with only
+one argument.
+
+ If you use a reentrant parser, you can optionally pass additional
+parameter information to it in a reentrant way. To do so, define the
+macro `YYPARSE_PARAM' as a variable name. This modifies the `yyparse'
+function to accept one argument, of type `void *', with that name.
+
+ When you call `yyparse', pass the address of an object, casting the
+address to `void *'. The grammar actions can refer to the contents of
+the object by casting the pointer value back to its proper type and
+then dereferencing it. Here's an example. Write this in the parser:
+
+ %{
+ struct parser_control
+ {
+ int nastiness;
+ int randomness;
+ };
+
+ #define YYPARSE_PARAM parm
+ %}
+
+Then call the parser like this:
+
+ struct parser_control
+ {
+ int nastiness;
+ int randomness;
+ };
+
+ ...
+
+ {
+ struct parser_control foo;
+ ... /* Store proper data in `foo'. */
+ value = yyparse ((void *) &foo);
+ ...
+ }
+
+In the grammar actions, use expressions like this to refer to the data:
+
+ ((struct parser_control *) parm)->randomness
+
+ If you wish to pass the additional parameter data to `yylex', define
+the macro `YYLEX_PARAM' just like `YYPARSE_PARAM', as shown here:
+
+ %{
+ struct parser_control
+ {
+ int nastiness;
+ int randomness;
+ };
+
+ #define YYPARSE_PARAM parm
+ #define YYLEX_PARAM parm
+ %}
+
+ You should then define `yylex' to accept one additional
+argument--the value of `parm'. (This makes either two or three
+arguments in total, depending on whether an argument of type `YYLTYPE'
+is passed.) You can declare the argument as a pointer to the proper
+object type, or you can declare it as `void *' and access the contents
+as shown above.
+
+ You can use `%pure_parser' to request a reentrant parser without
+also using `YYPARSE_PARAM'. Then you should call `yyparse' with no
+arguments, as usual.
+
+\1f
+File: bison.info, Node: Error Reporting, Next: Action Features, Prev: Lexical, Up: Interface
+
+The Error Reporting Function `yyerror'
+======================================
+
+ The Bison parser detects a "parse error" or "syntax error" whenever
+it reads a token which cannot satisfy any syntax rule. An action in
+the grammar can also explicitly proclaim an error, using the macro
+`YYERROR' (*note Special Features for Use in Actions: Action Features.).
+
+ The Bison parser expects to report the error by calling an error
+reporting function named `yyerror', which you must supply. It is
+called by `yyparse' whenever a syntax error is found, and it receives
+one argument. For a parse error, the string is normally
+`"parse error"'.
+
+ If you define the macro `YYERROR_VERBOSE' in the Bison declarations
+section (*note The Bison Declarations Section: Bison Declarations.),
+then Bison provides a more verbose and specific error message string
+instead of just plain `"parse error"'. It doesn't matter what
+definition you use for `YYERROR_VERBOSE', just whether you define it.
+
+ The parser can detect one other kind of error: stack overflow. This
+happens when the input contains constructions that are very deeply
+nested. It isn't likely you will encounter this, since the Bison
+parser extends its stack automatically up to a very large limit. But
+if overflow happens, `yyparse' calls `yyerror' in the usual fashion,
+except that the argument string is `"parser stack overflow"'.
+
+ The following definition suffices in simple programs:
+
+ void
+ yyerror (char *s)
+ {
+ fprintf (stderr, "%s\n", s);
+ }
+
+ After `yyerror' returns to `yyparse', the latter will attempt error
+recovery if you have written suitable error recovery grammar rules
+(*note Error Recovery::). If recovery is impossible, `yyparse' will
+immediately return 1.
+
+ The variable `yynerrs' contains the number of syntax errors
+encountered so far. Normally this variable is global; but if you
+request a pure parser (*note A Pure (Reentrant) Parser: Pure Decl.)
+then it is a local variable which only the actions can access.

+
+Special Features for Use in Actions
+===================================
+
+ Here is a table of Bison constructs, variables and macros that are
+useful in actions.
+
+`$$'
+ Acts like a variable that contains the semantic value for the
+ grouping made by the current rule. *Note Actions::.
+
+`$N'
+ Acts like a variable that contains the semantic value for the Nth

+ Return immediately from `yyparse', indicating failure. *Note The
+ Parser Function `yyparse': Parser Function.
+
+`YYACCEPT;'
+ Return immediately from `yyparse', indicating success. *Note The
+ Parser Function `yyparse': Parser Function.
+
+`YYBACKUP (TOKEN, VALUE);'
+ Unshift a token. This macro is allowed only for rules that reduce
+ a single value, and only when there is no look-ahead token. It
+ installs a look-ahead token with token type TOKEN and semantic
+ value VALUE; then it discards the value that was going to be
+ reduced by this rule.
+
+ If the macro is used when it is not valid, such as when there is a
+ look-ahead token already, then it reports a syntax error with a
+ message `cannot back up' and performs ordinary error recovery.
+
+ In either case, the rest of the action is not executed.
+
+`YYEMPTY'
+ Value stored in `yychar' when there is no look-ahead token.
+
+`YYERROR;'
+ Cause an immediate syntax error. This statement initiates error
+ recovery just as if the parser itself had detected an error;
+ however, it does not call `yyerror', and does not print any
+ message. If you want to print an error message, call `yyerror'
+ explicitly before the `YYERROR;' statement. *Note Error
+ Recovery::.
+
+`YYRECOVERING'
+ This macro stands for an expression that has the value 1 when the
+ parser is recovering from a syntax error, and 0 the rest of the
+ time. *Note Error Recovery::.
+
+`yychar'
+ Variable containing the current look-ahead token. (In a pure
+ parser, this is actually a local variable within `yyparse'.) When
+ there is no look-ahead token, the value `YYEMPTY' is stored in the
+ variable. *Note Look-Ahead Tokens: Look-Ahead.
+
+`yyclearin;'
+ Discard the current look-ahead token. This is useful primarily in
+ error rules. *Note Error Recovery::.
+
+`yyerrok;'
+ Resume generating error messages immediately for subsequent syntax
+ errors. This is useful primarily in error rules. *Note Error
+ Recovery::.
+
+`@N'
+ Acts like a structure variable containing information on the line
+ numbers and column numbers of the Nth component of the current
+ rule. The structure has four members, like this:
+
+ struct {
+ int first_line, last_line;
+ int first_column, last_column;
+ };
+
+ Thus, to get the starting line number of the third component, you
+ would use `@3.first_line'.
+
+ In order for the members of this structure to contain valid
+ information, you must make `yylex' supply this information about
+ each token. If you need only certain members, then `yylex' need
+ only fill in those members.
+
+ The use of this feature makes the parser noticeably slower.

+
+The Bison Parser Algorithm
+**************************
+
+ As Bison reads tokens, it pushes them onto a stack along with their
+semantic values. The stack is called the "parser stack". Pushing a
+token is traditionally called "shifting".
+
+ For example, suppose the infix calculator has read `1 + 5 *', with a
+`3' to come. The stack will have four elements, one for each token
+that was shifted.
+
+ But the stack does not always have an element for each token read.
+When the last N tokens and groupings shifted match the components of a
+grammar rule, they can be combined according to that rule. This is
+called "reduction". Those tokens and groupings are replaced on the
+stack by a single grouping whose symbol is the result (left hand side)
+of that rule. Running the rule's action is part of the process of
+reduction, because this is what computes the semantic value of the
+resulting grouping.
+
+ For example, if the infix calculator's parser stack contains this:
+
+ 1 + 5 * 3
+
+and the next input token is a newline character, then the last three
+elements can be reduced to 15 via the rule:
+
+ expr: expr '*' expr;
+
+Then the stack contains just these three elements:
+
+ 1 + 15
+
+At this point, another reduction can be made, resulting in the single
+value 16. Then the newline token can be shifted.
+
+ The parser tries, by shifts and reductions, to reduce the entire
+input down to a single grouping whose symbol is the grammar's
+start-symbol (*note Languages and Context-Free Grammars: Language and
+Grammar.).
+
+ This kind of parser is known in the literature as a bottom-up parser.

+
+Look-Ahead Tokens
+=================
+
+ The Bison parser does _not_ always reduce immediately as soon as the
+last N tokens and groupings match a rule. This is because such a
+simple strategy is inadequate to handle most languages. Instead, when a
+reduction is possible, the parser sometimes "looks ahead" at the next
+token in order to decide what to do.
+
+ When a token is read, it is not immediately shifted; first it
+becomes the "look-ahead token", which is not on the stack. Now the
+parser can perform one or more reductions of tokens and groupings on
+the stack, while the look-ahead token remains off to the side. When no
+more reductions should take place, the look-ahead token is shifted onto
+the stack. This does not mean that all possible reductions have been
+done; depending on the token type of the look-ahead token, some rules
+may choose to delay their application.
+
+ Here is a simple case where look-ahead is needed. These three rules
+define expressions which contain binary addition operators and postfix
+unary factorial operators (`!'), and allow parentheses for grouping.
+
+ expr: term '+' expr
+ | term
+ ;
+
+ term: '(' expr ')'
+ | term '!'
+ | NUMBER
+ ;
+
+ Suppose that the tokens `1 + 2' have been read and shifted; what
+should be done? If the following token is `)', then the first three
+tokens must be reduced to form an `expr'. This is the only valid
+course, because shifting the `)' would produce a sequence of symbols
+`term ')'', and no rule allows this.
+
+ If the following token is `!', then it must be shifted immediately so
+that `2 !' can be reduced to make a `term'. If instead the parser were
+to reduce before shifting, `1 + 2' would become an `expr'. It would
+then be impossible to shift the `!' because doing so would produce on
+the stack the sequence of symbols `expr '!''. No rule allows that
+sequence.
+
+ The current look-ahead token is stored in the variable `yychar'.
+*Note Special Features for Use in Actions: Action Features.
+

+File: bison.info, Node: Shift/Reduce, Next: Precedence, Prev: Look-Ahead, Up: Algorithm
+
+Shift/Reduce Conflicts
+======================
+
+ Suppose we are parsing a language which has if-then and if-then-else
+statements, with a pair of rules like this:
+
+ if_stmt:
+ IF expr THEN stmt
+ | IF expr THEN stmt ELSE stmt
+ ;
+
+Here we assume that `IF', `THEN' and `ELSE' are terminal symbols for
+specific keyword tokens.
+
+ When the `ELSE' token is read and becomes the look-ahead token, the
+contents of the stack (assuming the input is valid) are just right for
+reduction by the first rule. But it is also legitimate to shift the
+`ELSE', because that would lead to eventual reduction by the second
+rule.
+
+ This situation, where either a shift or a reduction would be valid,
+is called a "shift/reduce conflict". Bison is designed to resolve
+these conflicts by choosing to shift, unless otherwise directed by
+operator precedence declarations. To see the reason for this, let's
+contrast it with the other alternative.
+
+ Since the parser prefers to shift the `ELSE', the result is to attach
+the else-clause to the innermost if-statement, making these two inputs
+equivalent:
+
+ if x then if y then win (); else lose;
+
+ if x then do; if y then win (); else lose; end;
+
+ But if the parser chose to reduce when possible rather than shift,
+the result would be to attach the else-clause to the outermost
+if-statement, making these two inputs equivalent:
+
+ if x then if y then win (); else lose;
+
+ if x then do; if y then win (); end; else lose;
+
+ The conflict exists because the grammar as written is ambiguous:
+either parsing of the simple nested if-statement is legitimate. The
+established convention is that these ambiguities are resolved by
+attaching the else-clause to the innermost if-statement; this is what
+Bison accomplishes by choosing to shift rather than reduce. (It would
+ideally be cleaner to write an unambiguous grammar, but that is very
+hard to do in this case.) This particular ambiguity was first
+encountered in the specifications of Algol 60 and is called the
+"dangling `else'" ambiguity.
+
+ To avoid warnings from Bison about predictable, legitimate
+shift/reduce conflicts, use the `%expect N' declaration. There will be
+no warning as long as the number of shift/reduce conflicts is exactly N.
+*Note Suppressing Conflict Warnings: Expect Decl.
+
+ The definition of `if_stmt' above is solely to blame for the
+conflict, but the conflict does not actually appear without additional
+rules. Here is a complete Bison input file that actually manifests the
+conflict:
+
+ %token IF THEN ELSE variable
+ %%
+ stmt: expr
+ | if_stmt
+ ;
+
+ if_stmt:
+ IF expr THEN stmt
+ | IF expr THEN stmt ELSE stmt
+ ;

+
+Operator Precedence
+===================
+
+ Another situation where shift/reduce conflicts appear is in
+arithmetic expressions. Here shifting is not always the preferred
+resolution; the Bison declarations for operator precedence allow you to
+specify when to shift and when to reduce.
+
+* Menu:
+
+* Why Precedence:: An example showing why precedence is needed.

+
+\1f
+File: bison.info, Node: Why Precedence, Next: Using Precedence, Up: Precedence
+
+When Precedence is Needed
+-------------------------
+
+ Consider the following ambiguous grammar fragment (ambiguous because
+the input `1 - 2 * 3' can be parsed in two different ways):
+
+ expr: expr '-' expr
+ | expr '*' expr
+ | expr '<' expr
+ | '(' expr ')'
+ ...
+ ;
+
+Suppose the parser has seen the tokens `1', `-' and `2'; should it
+reduce them via the rule for the subtraction operator? It depends on
+the next token. Of course, if the next token is `)', we must reduce;
+shifting is invalid because no single rule can reduce the token
+sequence `- 2 )' or anything starting with that. But if the next token
+is `*' or `<', we have a choice: either shifting or reduction would
+allow the parse to complete, but with different results.
+
+ To decide which one Bison should do, we must consider the results.
+If the next operator token OP is shifted, then it must be reduced first
+in order to permit another opportunity to reduce the difference. The
+result is (in effect) `1 - (2 OP 3)'. On the other hand, if the
+subtraction is reduced before shifting OP, the result is
+`(1 - 2) OP 3'. Clearly, then, the choice of shift or reduce should
+depend on the relative precedence of the operators `-' and OP: `*'
+should be shifted first, but not `<'.
+
+ What about input such as `1 - 2 - 5'; should this be `(1 - 2) - 5'
+or should it be `1 - (2 - 5)'? For most operators we prefer the
+former, which is called "left association". The latter alternative,
+"right association", is desirable for assignment operators. The choice
+of left or right association is a matter of whether the parser chooses
+to shift or reduce when the stack contains `1 - 2' and the look-ahead
+token is `-': shifting makes right-associativity.
+
+\1f
+File: bison.info, Node: Using Precedence, Next: Precedence Examples, Prev: Why Precedence, Up: Precedence
+
+Specifying Operator Precedence
+------------------------------
+
+ Bison allows you to specify these choices with the operator
+precedence declarations `%left' and `%right'. Each such declaration
+contains a list of tokens, which are operators whose precedence and
+associativity is being declared. The `%left' declaration makes all
+those operators left-associative and the `%right' declaration makes
+them right-associative. A third alternative is `%nonassoc', which
+declares that it is a syntax error to find the same operator twice "in a
+row".
+
+ The relative precedence of different operators is controlled by the
+order in which they are declared. The first `%left' or `%right'
+declaration in the file declares the operators whose precedence is
+lowest, the next such declaration declares the operators whose
+precedence is a little higher, and so on.

+Precedence Examples
+-------------------
+
+ In our example, we would want the following declarations:
+
+ %left '<'
+ %left '-'
+ %left '*'
+
+ In a more complete example, which supports other operators as well,
+we would declare them in groups of equal precedence. For example,
+`'+'' is declared with `'-'':
+
+ %left '<' '>' '=' NE LE GE
+ %left '+' '-'
+ %left '*' '/'
+
+(Here `NE' and so on stand for the operators for "not equal" and so on.
+We assume that these tokens are more than one character long and
+therefore are represented by names, not character literals.)

+How Precedence Works
+--------------------
+
+ The first effect of the precedence declarations is to assign
+precedence levels to the terminal symbols declared. The second effect
+is to assign precedence levels to certain rules: each rule gets its
+precedence from the last terminal symbol mentioned in the components.
+(You can also specify explicitly the precedence of a rule. *Note
+Context-Dependent Precedence: Contextual Precedence.)
+
+ Finally, the resolution of conflicts works by comparing the
+precedence of the rule being considered with that of the look-ahead
+token. If the token's precedence is higher, the choice is to shift.
+If the rule's precedence is higher, the choice is to reduce. If they
+have equal precedence, the choice is made based on the associativity of
+that precedence level. The verbose output file made by `-v' (*note
+Invoking Bison: Invocation.) says how each conflict was resolved.
+
+ Not all rules and not all tokens have precedence. If either the
+rule or the look-ahead token has no precedence, then the default is to
+shift.

+
+Context-Dependent Precedence
+============================
+
+ Often the precedence of an operator depends on the context. This
+sounds outlandish at first, but it is really very common. For example,
+a minus sign typically has a very high precedence as a unary operator,
+and a somewhat lower precedence (lower than multiplication) as a binary
+operator.
+
+ The Bison precedence declarations, `%left', `%right' and
+`%nonassoc', can only be used once for a given token; so a token has
+only one precedence declared in this way. For context-dependent
+precedence, you need to use an additional mechanism: the `%prec'
+modifier for rules.
+
+ The `%prec' modifier declares the precedence of a particular rule by
+specifying a terminal symbol whose precedence should be used for that
+rule. It's not necessary for that symbol to appear otherwise in the
+rule. The modifier's syntax is:
+
+ %prec TERMINAL-SYMBOL
+
+and it is written after the components of the rule. Its effect is to
+assign the rule the precedence of TERMINAL-SYMBOL, overriding the
+precedence that would be deduced for it in the ordinary way. The
+altered rule precedence then affects how conflicts involving that rule
+are resolved (*note Operator Precedence: Precedence.).
+
+ Here is how `%prec' solves the problem of unary minus. First,
+declare a precedence for a fictitious terminal symbol named `UMINUS'.
+There are no tokens of this type, but the symbol serves to stand for its
+precedence:
+
+ ...
+ %left '+' '-'
+ %left '*'
+ %left UMINUS
+
+ Now the precedence of `UMINUS' can be used in specific rules:
+
+ exp: ...
+ | exp '-' exp
+ ...
+ | '-' exp %prec UMINUS

+Parser States
+=============
+
+ The function `yyparse' is implemented using a finite-state machine.
+The values pushed on the parser stack are not simply token type codes;
+they represent the entire sequence of terminal and nonterminal symbols
+at or near the top of the stack. The current state collects all the
+information about previous input which is relevant to deciding what to
+do next.
+
+ Each time a look-ahead token is read, the current parser state
+together with the type of look-ahead token are looked up in a table.
+This table entry can say, "Shift the look-ahead token." In this case,
+it also specifies the new parser state, which is pushed onto the top of
+the parser stack. Or it can say, "Reduce using rule number N." This
+means that a certain number of tokens or groupings are taken off the
+top of the stack, and replaced by one grouping. In other words, that
+number of states are popped from the stack, and one new state is pushed.
+
+ There is one other alternative: the table can say that the
+look-ahead token is erroneous in the current state. This causes error
+processing to begin (*note Error Recovery::).

+
+Reduce/Reduce Conflicts
+=======================
+
+ A reduce/reduce conflict occurs if there are two or more rules that
+apply to the same sequence of input. This usually indicates a serious
+error in the grammar.
+
+ For example, here is an erroneous attempt to define a sequence of
+zero or more `word' groupings.
+
+ sequence: /* empty */
+ { printf ("empty sequence\n"); }
+ | maybeword
+ | sequence word
+ { printf ("added word %s\n", $2); }
+ ;
+
+ maybeword: /* empty */
+ { printf ("empty maybeword\n"); }
+ | word
+ { printf ("single word %s\n", $1); }
+ ;
+
+The error is an ambiguity: there is more than one way to parse a single
+`word' into a `sequence'. It could be reduced to a `maybeword' and
+then into a `sequence' via the second rule. Alternatively,
+nothing-at-all could be reduced into a `sequence' via the first rule,
+and this could be combined with the `word' using the third rule for
+`sequence'.
+
+ There is also more than one way to reduce nothing-at-all into a
+`sequence'. This can be done directly via the first rule, or
+indirectly via `maybeword' and then the second rule.
+
+ You might think that this is a distinction without a difference,
+because it does not change whether any particular input is valid or
+not. But it does affect which actions are run. One parsing order runs
+the second rule's action; the other runs the first rule's action and
+the third rule's action. In this example, the output of the program
+changes.
+
+ Bison resolves a reduce/reduce conflict by choosing to use the rule
+that appears first in the grammar, but it is very risky to rely on
+this. Every reduce/reduce conflict must be studied and usually
+eliminated. Here is the proper way to define `sequence':
+
+ sequence: /* empty */
+ { printf ("empty sequence\n"); }
+ | sequence word
+ { printf ("added word %s\n", $2); }
+ ;
+
+ Here is another common error that yields a reduce/reduce conflict:
+
+ sequence: /* empty */
+ | sequence words
+ | sequence redirects
+ ;
+
+ words: /* empty */
+ | words word
+ ;
+
+ redirects:/* empty */
+ | redirects redirect
+ ;
+
+The intention here is to define a sequence which can contain either
+`word' or `redirect' groupings. The individual definitions of
+`sequence', `words' and `redirects' are error-free, but the three
+together make a subtle ambiguity: even an empty input can be parsed in
+infinitely many ways!
+
+ Consider: nothing-at-all could be a `words'. Or it could be two
+`words' in a row, or three, or any number. It could equally well be a
+`redirects', or two, or any number. Or it could be a `words' followed
+by three `redirects' and another `words'. And so on.
+
+ Here are two ways to correct these rules. First, to make it a
+single level of sequence:
+
+ sequence: /* empty */
+ | sequence word
+ | sequence redirect
+ ;
+
+ Second, to prevent either a `words' or a `redirects' from being
+empty:
+
+ sequence: /* empty */
+ | sequence words
+ | sequence redirects
+ ;
+
+ words: word
+ | words word
+ ;
+
+ redirects:redirect
+ | redirects redirect
+ ;

+
+Mysterious Reduce/Reduce Conflicts
+==================================
+
+ Sometimes reduce/reduce conflicts can occur that don't look
+warranted. Here is an example:
+
+ %token ID
+
+ %%
+ def: param_spec return_spec ','
+ ;
+ param_spec:
+ type
+ | name_list ':' type
+ ;
+ return_spec:
+ type
+ | name ':' type
+ ;
+ type: ID
+ ;
+ name: ID
+ ;
+ name_list:
+ name
+ | name ',' name_list
+ ;
+
+ It would seem that this grammar can be parsed with only a single
+token of look-ahead: when a `param_spec' is being read, an `ID' is a
+`name' if a comma or colon follows, or a `type' if another `ID'
+follows. In other words, this grammar is LR(1).
+
+ However, Bison, like most parser generators, cannot actually handle
+all LR(1) grammars. In this grammar, two contexts, that after an `ID'
+at the beginning of a `param_spec' and likewise at the beginning of a
+`return_spec', are similar enough that Bison assumes they are the same.
+They appear similar because the same set of rules would be active--the
+rule for reducing to a `name' and that for reducing to a `type'. Bison
+is unable to determine at that stage of processing that the rules would
+require different look-ahead tokens in the two contexts, so it makes a
+single parser state for them both. Combining the two contexts causes a
+conflict later. In parser terminology, this occurrence means that the
+grammar is not LALR(1).
+
+ In general, it is better to fix deficiencies than to document them.
+But this particular deficiency is intrinsically hard to fix; parser
+generators that can handle LR(1) grammars are hard to write and tend to
+produce parsers that are very large. In practice, Bison is more useful
+as it is now.
+
+ When the problem arises, you can often fix it by identifying the two
+parser states that are being confused, and adding something to make them
+look distinct. In the above example, adding one rule to `return_spec'
+as follows makes the problem go away:
+
+ %token BOGUS
+ ...
+ %%
+ ...
+ return_spec:
+ type
+ | name ':' type
+ /* This rule is never used. */
+ | ID BOGUS
+ ;
+
+ This corrects the problem because it introduces the possibility of an
+additional active rule in the context after the `ID' at the beginning of
+`return_spec'. This rule is not active in the corresponding context in
+a `param_spec', so the two contexts receive distinct parser states. As
+long as the token `BOGUS' is never generated by `yylex', the added rule
+cannot alter the way actual input is parsed.
+
+ In this particular example, there is another way to solve the
+problem: rewrite the rule for `return_spec' to use `ID' directly
+instead of via `name'. This also causes the two confusing contexts to
+have different sets of active rules, because the one for `return_spec'
+activates the altered rule for `return_spec' rather than the one for
+`name'.
+
+ param_spec:
+ type
+ | name_list ':' type
+ ;
+ return_spec:
+ type
+ | ID ':' type
+ ;
+
+\1f
+File: bison.info, Node: Stack Overflow, Prev: Mystery Conflicts, Up: Algorithm
+
+Stack Overflow, and How to Avoid It
+===================================
+
+ The Bison parser stack can overflow if too many tokens are shifted
+and not reduced. When this happens, the parser function `yyparse'
+returns a nonzero value, pausing only to call `yyerror' to report the
+overflow.
+
+ By defining the macro `YYMAXDEPTH', you can control how deep the
+parser stack can become before a stack overflow occurs. Define the
+macro with a value that is an integer. This value is the maximum number
+of tokens that can be shifted (and not reduced) before overflow. It
+must be a constant expression whose value is known at compile time.
+
+ The stack space allowed is not necessarily allocated. If you
+specify a large value for `YYMAXDEPTH', the parser actually allocates a
+small stack at first, and then makes it bigger by stages as needed.
+This increasing allocation happens automatically and silently.
+Therefore, you do not need to make `YYMAXDEPTH' painfully small merely
+to save space for ordinary inputs that do not need much stack.
+
+ The default value of `YYMAXDEPTH', if you do not define it, is 10000.
+
+ You can control how much stack is allocated initially by defining the
+macro `YYINITDEPTH'. This value too must be a compile-time constant
+integer. The default is 200.

+
+Error Recovery
+**************
+
+ It is not usually acceptable to have a program terminate on a parse
+error. For example, a compiler should recover sufficiently to parse the
+rest of the input file and check it for errors; a calculator should
+accept another expression.
+
+ In a simple interactive command parser where each input is one line,
+it may be sufficient to allow `yyparse' to return 1 on error and have
+the caller ignore the rest of the input line when that happens (and
+then call `yyparse' again). But this is inadequate for a compiler,
+because it forgets all the syntactic context leading up to the error.
+A syntax error deep within a function in the compiler input should not
+cause the compiler to treat the following line like the beginning of a
+source file.
+
+ You can define how to recover from a syntax error by writing rules to
+recognize the special token `error'. This is a terminal symbol that is
+always defined (you need not declare it) and reserved for error
+handling. The Bison parser generates an `error' token whenever a
+syntax error happens; if you have provided a rule to recognize this
+token in the current context, the parse can continue.
+
+ For example:
+
+ stmnts: /* empty string */
+ | stmnts '\n'
+ | stmnts exp '\n'
+ | stmnts error '\n'
+
+ The fourth rule in this example says that an error followed by a
+newline makes a valid addition to any `stmnts'.
+
+ What happens if a syntax error occurs in the middle of an `exp'? The
+error recovery rule, interpreted strictly, applies to the precise
+sequence of a `stmnts', an `error' and a newline. If an error occurs in
+the middle of an `exp', there will probably be some additional tokens
+and subexpressions on the stack after the last `stmnts', and there will
+be tokens to read before the next newline. So the rule is not
+applicable in the ordinary way.
+
+ But Bison can force the situation to fit the rule, by discarding
+part of the semantic context and part of the input. First it discards
+states and objects from the stack until it gets back to a state in
+which the `error' token is acceptable. (This means that the
+subexpressions already parsed are discarded, back to the last complete
+`stmnts'.) At this point the `error' token can be shifted. Then, if
+the old look-ahead token is not acceptable to be shifted next, the
+parser reads tokens and discards them until it finds a token which is
+acceptable. In this example, Bison reads and discards input until the
+next newline so that the fourth rule can apply.
+
+ The choice of error rules in the grammar is a choice of strategies
+for error recovery. A simple and useful strategy is simply to skip the
+rest of the current input line or current statement if an error is
+detected:
+
+ stmnt: error ';' /* on error, skip until ';' is read */
+
+ It is also useful to recover to the matching close-delimiter of an
+opening-delimiter that has already been parsed. Otherwise the
+close-delimiter will probably appear to be unmatched, and generate
+another, spurious error message:
+
+ primary: '(' expr ')'
+ | '(' error ')'
+ ...
+ ;
+
+ Error recovery strategies are necessarily guesses. When they guess
+wrong, one syntax error often leads to another. In the above example,
+the error recovery rule guesses that an error is due to bad input
+within one `stmnt'. Suppose that instead a spurious semicolon is
+inserted in the middle of a valid `stmnt'. After the error recovery
+rule recovers from the first error, another syntax error will be found
+straightaway, since the text following the spurious semicolon is also
+an invalid `stmnt'.
+
+ To prevent an outpouring of error messages, the parser will output
+no error message for another syntax error that happens shortly after
+the first; only after three consecutive input tokens have been
+successfully shifted will error messages resume.
+
+ Note that rules which accept the `error' token may have actions, just
+as any other rules can.
+
+ You can make error messages resume immediately by using the macro
+`yyerrok' in an action. If you do this in the error rule's action, no
+error messages will be suppressed. This macro requires no arguments;
+`yyerrok;' is a valid C statement.
+
+ The previous look-ahead token is reanalyzed immediately after an
+error. If this is unacceptable, then the macro `yyclearin' may be used
+to clear this token. Write the statement `yyclearin;' in the error
+rule's action.
+
+ For example, suppose that on a parse error, an error handling
+routine is called that advances the input stream to some point where
+parsing should once again commence. The next symbol returned by the
+lexical scanner is probably correct. The previous look-ahead token
+ought to be discarded with `yyclearin;'.
+
+ The macro `YYRECOVERING' stands for an expression that has the value
+1 when the parser is recovering from a syntax error, and 0 the rest of
+the time. A value of 1 indicates that error messages are currently
+suppressed for new syntax errors.

+
+Handling Context Dependencies
+*****************************
+
+ The Bison paradigm is to parse tokens first, then group them into
+larger syntactic units. In many languages, the meaning of a token is
+affected by its context. Although this violates the Bison paradigm,
+certain techniques (known as "kludges") may enable you to write Bison
+parsers for such languages.
+
+* Menu:
+
+* Semantic Tokens:: Token parsing can depend on the semantic context.
+* Lexical Tie-ins:: Token parsing can depend on the syntactic context.
+* Tie-in Recovery:: Lexical tie-ins have implications for how
+ error recovery rules must be written.
+
+ (Actually, "kludge" means any technique that gets its job done but is
+neither clean nor robust.)
+
+\1f
+File: bison.info, Node: Semantic Tokens, Next: Lexical Tie-ins, Up: Context Dependency
+
+Semantic Info in Token Types
+============================
+
+ The C language has a context dependency: the way an identifier is
+used depends on what its current meaning is. For example, consider
+this:
+
+ foo (x);
+
+ This looks like a function call statement, but if `foo' is a typedef
+name, then this is actually a declaration of `x'. How can a Bison
+parser for C decide how to parse this input?
+
+ The method used in GNU C is to have two different token types,
+`IDENTIFIER' and `TYPENAME'. When `yylex' finds an identifier, it
+looks up the current declaration of the identifier in order to decide
+which token type to return: `TYPENAME' if the identifier is declared as
+a typedef, `IDENTIFIER' otherwise.
+
+ The grammar rules can then express the context dependency by the
+choice of token type to recognize. `IDENTIFIER' is accepted as an
+expression, but `TYPENAME' is not. `TYPENAME' can start a declaration,
+but `IDENTIFIER' cannot. In contexts where the meaning of the
+identifier is _not_ significant, such as in declarations that can
+shadow a typedef name, either `TYPENAME' or `IDENTIFIER' is
+accepted--there is one rule for each of the two token types.
+
+ This technique is simple to use if the decision of which kinds of
+identifiers to allow is made at a place close to where the identifier is
+parsed. But in C this is not always so: C allows a declaration to
+redeclare a typedef name provided an explicit type has been specified
+earlier:
+
+ typedef int foo, bar, lose;
+ static foo (bar); /* redeclare `bar' as static variable */
+ static int foo (lose); /* redeclare `foo' as function */
+
+ Unfortunately, the name being declared is separated from the
+declaration construct itself by a complicated syntactic structure--the
+"declarator".
+
+ As a result, part of the Bison parser for C needs to be duplicated,
+with all the nonterminal names changed: once for parsing a declaration
+in which a typedef name can be redefined, and once for parsing a
+declaration in which that can't be done. Here is a part of the
+duplication, with actions omitted for brevity:
+
+ initdcl:
+ declarator maybeasm '='
+ init
+ | declarator maybeasm
+ ;
+
+ notype_initdcl:
+ notype_declarator maybeasm '='
+ init
+ | notype_declarator maybeasm
+ ;
+
+Here `initdcl' can redeclare a typedef name, but `notype_initdcl'
+cannot. The distinction between `declarator' and `notype_declarator'
+is the same sort of thing.
+
+ There is some similarity between this technique and a lexical tie-in
+(described next), in that information which alters the lexical analysis
+is changed during parsing by other parts of the program. The
+difference is here the information is global, and is used for other
+purposes in the program. A true lexical tie-in has a special-purpose
+flag controlled by the syntactic context.
+
+\1f
+File: bison.info, Node: Lexical Tie-ins, Next: Tie-in Recovery, Prev: Semantic Tokens, Up: Context Dependency
+
+Lexical Tie-ins
+===============
+
+ One way to handle context-dependency is the "lexical tie-in": a flag
+which is set by Bison actions, whose purpose is to alter the way tokens
+are parsed.
+
+ For example, suppose we have a language vaguely like C, but with a
+special construct `hex (HEX-EXPR)'. After the keyword `hex' comes an
+expression in parentheses in which all integers are hexadecimal. In
+particular, the token `a1b' must be treated as an integer rather than
+as an identifier if it appears in that context. Here is how you can do
+it:
+
+ %{
+ int hexflag;
+ %}
+ %%
+ ...
+ expr: IDENTIFIER
+ | constant
+ | HEX '('
+ { hexflag = 1; }
+ expr ')'
+ { hexflag = 0;
+ $$ = $4; }
+ | expr '+' expr
+ { $$ = make_sum ($1, $3); }
+ ...
+ ;
+
+ constant:
+ INTEGER
+ | STRING
+ ;
+
+Here we assume that `yylex' looks at the value of `hexflag'; when it is
+nonzero, all integers are parsed in hexadecimal, and tokens starting
+with letters are parsed as integers if possible.
+
+ The declaration of `hexflag' shown in the C declarations section of
+the parser file is needed to make it accessible to the actions (*note
+The C Declarations Section: C Declarations.). You must also write the
+code in `yylex' to obey the flag.
+
+\1f
+File: bison.info, Node: Tie-in Recovery, Prev: Lexical Tie-ins, Up: Context Dependency
+
+Lexical Tie-ins and Error Recovery
+==================================
+
+ Lexical tie-ins make strict demands on any error recovery rules you
+have. *Note Error Recovery::.
+
+ The reason for this is that the purpose of an error recovery rule is
+to abort the parsing of one construct and resume in some larger
+construct. For example, in C-like languages, a typical error recovery
+rule is to skip tokens until the next semicolon, and then start a new
+statement, like this:
+
+ stmt: expr ';'
+ | IF '(' expr ')' stmt { ... }
+ ...
+ error ';'
+ { hexflag = 0; }
+ ;
+
+ If there is a syntax error in the middle of a `hex (EXPR)'
+construct, this error rule will apply, and then the action for the
+completed `hex (EXPR)' will never run. So `hexflag' would remain set
+for the entire rest of the input, or until the next `hex' keyword,
+causing identifiers to be misinterpreted as integers.
+
+ To avoid this problem the error recovery rule itself clears
+`hexflag'.
+
+ There may also be an error recovery rule that works within
+expressions. For example, there could be a rule which applies within
+parentheses and skips to the close-parenthesis:
+
+ expr: ...
+ | '(' expr ')'
+ { $$ = $2; }
+ | '(' error ')'
+ ...
+
+ If this rule acts within the `hex' construct, it is not going to
+abort that construct (since it applies to an inner level of parentheses
+within the construct). Therefore, it should not clear the flag: the
+rest of the `hex' construct should be parsed with the flag still in
+effect.
+
+ What if there is an error recovery rule which might abort out of the
+`hex' construct or might not, depending on circumstances? There is no
+way you can write the action to determine whether a `hex' construct is
+being aborted or not. So if you are using a lexical tie-in, you had
+better make sure your error recovery rules are not of this kind. Each
+rule must be such that you can be sure that it always will, or always
+won't, have to clear the flag.

+
+Debugging Your Parser
+*********************
+
+ If a Bison grammar compiles properly but doesn't do what you want
+when it runs, the `yydebug' parser-trace feature can help you figure
+out why.
+
+ To enable compilation of trace facilities, you must define the macro
+`YYDEBUG' when you compile the parser. You could use `-DYYDEBUG=1' as
+a compiler option or you could put `#define YYDEBUG 1' in the C
+declarations section of the grammar file (*note The C Declarations
+Section: C Declarations.). Alternatively, use the `-t' option when you
+run Bison (*note Invoking Bison: Invocation.). We always define
+`YYDEBUG' so that debugging is always possible.
+
+ The trace facility uses `stderr', so you must add
+`#include <stdio.h>' to the C declarations section unless it is already
+there.
+
+ Once you have compiled the program with trace facilities, the way to
+request a trace is to store a nonzero value in the variable `yydebug'.
+You can do this by making the C code do it (in `main', perhaps), or you
+can alter the value with a C debugger.
+
+ Each step taken by the parser when `yydebug' is nonzero produces a
+line or two of trace information, written on `stderr'. The trace
+messages tell you these things:
+
+ * Each time the parser calls `yylex', what kind of token was read.
+
+ * Each time a token is shifted, the depth and complete contents of
+ the state stack (*note Parser States::).
+
+ * Each time a rule is reduced, which rule it is, and the complete
+ contents of the state stack afterward.
+
+ To make sense of this information, it helps to refer to the listing
+file produced by the Bison `-v' option (*note Invoking Bison:
+Invocation.). This file shows the meaning of each state in terms of
+positions in various rules, and also what each state will do with each
+possible input token. As you read the successive trace messages, you
+can see that the parser is functioning according to its specification
+in the listing file. Eventually you will arrive at the place where
+something undesirable happens, and you will see which parts of the
+grammar are to blame.
+
+ The parser file is a C program and you can use C debuggers on it,
+but it's not easy to interpret what it is doing. The parser function
+is a finite-state machine interpreter, and aside from the actions it
+executes the same code over and over. Only the values of variables
+show where in the grammar it is working.
+
+ The debugging information normally gives the token type of each token
+read, but not its semantic value. You can optionally define a macro
+named `YYPRINT' to provide a way to print the value. If you define
+`YYPRINT', it should take three arguments. The parser will pass a
+standard I/O stream, the numeric code for the token type, and the token
+value (from `yylval').
+
+ Here is an example of `YYPRINT' suitable for the multi-function
+calculator (*note Declarations for `mfcalc': Mfcalc Decl.):
+
+ #define YYPRINT(file, type, value) yyprint (file, type, value)
+
+ static void
+ yyprint (FILE *file, int type, YYSTYPE value)
+ {
+ if (type == VAR)
+ fprintf (file, " %s", value.tptr->name);
+ else if (type == NUM)
+ fprintf (file, " %d", value.val);
+ }

+ The usual way to invoke Bison is as follows:
+
+ bison INFILE
+
+ Here INFILE is the grammar file name, which usually ends in `.y'.
+The parser file's name is made by replacing the `.y' with `.tab.c'.
+Thus, the `bison foo.y' filename yields `foo.tab.c', and the `bison
+hack/foo.y' filename yields `hack/foo.tab.c'.

+
+Bison Options
+=============
+
+ Bison supports both traditional single-letter options and mnemonic
+long option names. Long option names are indicated with `--' instead of
+`-'. Abbreviations for option names are allowed as long as they are
+unique. When a long option takes an argument, like `--file-prefix',
+connect the option name and the argument with `='.
+
+ Here is a list of options that can be used with Bison, alphabetized
+by short option. It is followed by a cross key alphabetized by long
+option.
+
+Operations modes:
+`-h'
+`--help'
+ Print a summary of the command-line options to Bison and exit.
+
+`-V'
+`--version'
+ Print the version number of Bison and exit.
+
+`-y'
+`--yacc'
+`--fixed-output-files'
+ Equivalent to `-o y.tab.c'; the parser output file is called
+ `y.tab.c', and the other outputs are called `y.output' and
+ `y.tab.h'. The purpose of this option is to imitate Yacc's output
+ file name conventions. Thus, the following shell script can
+ substitute for Yacc:
+
+ bison -y $*
+
+Tuning the parser:
+
+`-t'
+`--debug'
+ Output a definition of the macro `YYDEBUG' into the parser file,
+ so that the debugging facilities are compiled. *Note Debugging
+ Your Parser: Debugging.
+
+`--locations'
+ Pretend that `%locactions' was specified. *Note Decl Summary::.
+
+`-p PREFIX'
+`--name-prefix=PREFIX'
+ Rename the external symbols used in the parser so that they start
+ with PREFIX instead of `yy'. The precise list of symbols renamed
+ is `yyparse', `yylex', `yyerror', `yynerrs', `yylval', `yychar'
+ and `yydebug'.
+
+ For example, if you use `-p c', the names become `cparse', `clex',
+ and so on.
+
+ *Note Multiple Parsers in the Same Program: Multiple Parsers.
+
+`-l'
+`--no-lines'
+ Don't put any `#line' preprocessor commands in the parser file.
+ Ordinarily Bison puts them in the parser file so that the C
+ compiler and debuggers will associate errors with your source
+ file, the grammar file. This option causes them to associate
+ errors with the parser file, treating it as an independent source
+ file in its own right.
+
+`-n'
+`--no-parser'
+ Do not include any C code in the parser file; generate tables
+ only. The parser file contains just `#define' directives and
+ static variable declarations.
+
+ This option also tells Bison to write the C code for the grammar
+ actions into a file named `FILENAME.act', in the form of a
+ brace-surrounded body fit for a `switch' statement.
+
+`-r'
+`--raw'
+ Pretend that `%raw' was specified. *Note Decl Summary::.
+
+`-k'
+`--token-table'
+ Pretend that `%token_table' was specified. *Note Decl Summary::.
+
+Adjust the output:
+
+`-d'
+`--defines'
+ Write an extra output file containing macro definitions for the
+ token type names defined in the grammar and the semantic value type
+ `YYSTYPE', as well as a few `extern' variable declarations.
+
+ If the parser output file is named `NAME.c' then this file is
+ named `NAME.h'.
+
+ This output file is essential if you wish to put the definition of
+ `yylex' in a separate source file, because `yylex' needs to be
+ able to refer to token type codes and the variable `yylval'.
+ *Note Semantic Values of Tokens: Token Values.
+
+`-b FILE-PREFIX'
+`--file-prefix=PREFIX'
+ Specify a prefix to use for all Bison output file names. The
+ names are chosen as if the input file were named `PREFIX.c'.
+
+`-v'
+`--verbose'
+ Write an extra output file containing verbose descriptions of the
+ parser states and what is done for each type of look-ahead token in
+ that state.
+
+ This file also describes all the conflicts, both those resolved by
+ operator precedence and the unresolved ones.
+
+ The file's name is made by removing `.tab.c' or `.c' from the
+ parser output file name, and adding `.output' instead.
+
+ Therefore, if the input file is `foo.y', then the parser file is
+ called `foo.tab.c' by default. As a consequence, the verbose
+ output file is called `foo.output'.
+
+`-o OUTFILE'
+`--output-file=OUTFILE'
+ Specify the name OUTFILE for the parser file.
+
+ The other output files' names are constructed from OUTFILE as
+ described under the `-v' and `-d' options.

+
+Environment Variables
+=====================
+
+ Here is a list of environment variables which affect the way Bison
+runs.
+
+`BISON_SIMPLE'
+`BISON_HAIRY'
+ Much of the parser generated by Bison is copied verbatim from a
+ file called `bison.simple'. If Bison cannot find that file, or if
+ you would like to direct Bison to use a different copy, setting the
+ environment variable `BISON_SIMPLE' to the path of the file will
+ cause Bison to use that copy instead.
+
+ When the `%semantic_parser' declaration is used, Bison copies from
+ a file called `bison.hairy' instead. The location of this file can
+ also be specified or overridden in a similar fashion, with the
+ `BISON_HAIRY' environment variable.

+
+Invoking Bison under VMS
+========================
+
+ The command line syntax for Bison on VMS is a variant of the usual
+Bison command syntax--adapted to fit VMS conventions.
+
+ To find the VMS equivalent for any Bison option, start with the long
+option, and substitute a `/' for the leading `--', and substitute a `_'
+for each `-' in the name of the long option. For example, the
+following invocation under VMS:
+
+ bison /debug/name_prefix=bar foo.y
+
+is equivalent to the following command under POSIX.
+
+ bison --debug --name-prefix=bar foo.y
+
+ The VMS file system does not permit filenames such as `foo.tab.c'.
+In the above example, the output file would instead be named
+`foo_tab.c'.

+Bison Symbols
+*************
+
+`error'
+ A token name reserved for error recovery. This token may be used
+ in grammar rules so as to allow the Bison parser to recognize an
+ error in the grammar without halting the process. In effect, a
+ sentence containing an error may be recognized as valid. On a
+ parse error, the token `error' becomes the current look-ahead
+ token. Actions corresponding to `error' are then executed, and
+ the look-ahead token is reset to the token that originally caused
+ the violation. *Note Error Recovery::.
+
+`YYABORT'
+ Macro to pretend that an unrecoverable syntax error has occurred,
+ by making `yyparse' return 1 immediately. The error reporting
+ function `yyerror' is not called. *Note The Parser Function
+ `yyparse': Parser Function.
+
+`YYACCEPT'
+ Macro to pretend that a complete utterance of the language has been
+ read, by making `yyparse' return 0 immediately. *Note The Parser

+
+Backus-Naur Form (BNF)
+ Formal method of specifying context-free grammars. BNF was first
+ used in the `ALGOL-60' report, 1963. *Note Languages and
+ Context-Free Grammars: Language and Grammar.
+
+Context-free grammars
+ Grammars specified as rules that can be applied regardless of
+ context. Thus, if there is a rule which says that an integer can
+ be used as an expression, integers are allowed _anywhere_ an
+ expression is permitted. *Note Languages and Context-Free
+ Grammars: Language and Grammar.
+
+Dynamic allocation
+ Allocation of memory that occurs during execution, rather than at
+ compile time or on entry to a function.
+
+Empty string
+ Analogous to the empty set in set theory, the empty string is a
+ character string of length zero.
+
+Finite-state stack machine
+ A "machine" that has discrete states in which it is said to exist
+ at each instant in time. As input to the machine is processed, the
+ machine moves from state to state as specified by the logic of the
+ machine. In the case of the parser, the input is the language
+ being parsed, and the states correspond to various stages in the
+ grammar rules. *Note The Bison Parser Algorithm: Algorithm.
+
+Grouping
+ A language construct that is (in general) grammatically divisible;
+ for example, `expression' or `declaration' in C. *Note Languages
+ and Context-Free Grammars: Language and Grammar.
+
+Infix operator
+ An arithmetic operator that is placed between the operands on
+ which it performs some operation.
+
+Input stream
+ A continuous flow of data between devices or programs.
+
+Language construct
+ One of the typical usage schemas of the language. For example,
+ one of the constructs of the C language is the `if' statement.
+ *Note Languages and Context-Free Grammars: Language and Grammar.
+
+Left associativity
+ Operators having left associativity are analyzed from left to
+ right: `a+b+c' first computes `a+b' and then combines with `c'.
+ *Note Operator Precedence: Precedence.
+
+Left recursion
+ A rule whose result symbol is also its first component symbol; for
+ example, `expseq1 : expseq1 ',' exp;'. *Note Recursive Rules:
+ Recursion.
+
+Left-to-right parsing
+ Parsing a sentence of a language by analyzing it token by token
+ from left to right. *Note The Bison Parser Algorithm: Algorithm.
+
+Lexical analyzer (scanner)
+ A function that reads an input stream and returns tokens one by
+ one. *Note The Lexical Analyzer Function `yylex': Lexical.
+
+Lexical tie-in
+ A flag, set by actions in the grammar rules, which alters the way
+ tokens are parsed. *Note Lexical Tie-ins::.
+
+Literal string token
+ A token which consists of two or more fixed characters. *Note
+ Symbols::.
+
+Look-ahead token
+ A token already read but not yet shifted. *Note Look-Ahead
+ Tokens: Look-Ahead.
+
+LALR(1)
+ The class of context-free grammars that Bison (like most other
+ parser generators) can handle; a subset of LR(1). *Note
+ Mysterious Reduce/Reduce Conflicts: Mystery Conflicts.
+
+LR(1)
+ The class of context-free grammars in which at most one token of
+ look-ahead is needed to disambiguate the parsing of any piece of
+ input.
+
+Nonterminal symbol
+ A grammar symbol standing for a grammatical construct that can be
+ expressed through rules in terms of smaller constructs; in other
+ words, a construct that is not a token. *Note Symbols::.
+
+Parse error
+ An error encountered during parsing of an input stream due to
+ invalid syntax. *Note Error Recovery::.
+
+Parser
+ A function that recognizes valid sentences of a language by
+ analyzing the syntax structure of a set of tokens passed to it
+ from a lexical analyzer.
+
+Postfix operator
+ An arithmetic operator that is placed after the operands upon
+ which it performs some operation.
+
+Reduction
+ Replacing a string of nonterminals and/or terminals with a single
+ nonterminal, according to a grammar rule. *Note The Bison Parser
+ Algorithm: Algorithm.
+
+Reentrant
+ A reentrant subprogram is a subprogram which can be in invoked any
+ number of times in parallel, without interference between the
+ various invocations. *Note A Pure (Reentrant) Parser: Pure Decl.
+
+Reverse polish notation
+ A language in which all operators are postfix operators.
+
+Right recursion
+ A rule whose result symbol is also its last component symbol; for
+ example, `expseq1: exp ',' expseq1;'. *Note Recursive Rules:
+ Recursion.
+
+Semantics
+ In computer languages, the semantics are specified by the actions
+ taken for each instance of the language, i.e., the meaning of each
+ statement. *Note Defining Language Semantics: Semantics.
+
+Shift
+ A parser is said to shift when it makes the choice of analyzing
+ further input from the stream rather than reducing immediately some
+ already-recognized rule. *Note The Bison Parser Algorithm:
+ Algorithm.
+
+Single-character literal
+ A single character that is recognized and interpreted as is.
+ *Note From Formal Rules to Bison Input: Grammar in Bison.
+
+Start symbol
+ The nonterminal symbol that stands for a complete valid utterance
+ in the language being parsed. The start symbol is usually listed
+ as the first nonterminal symbol in a language specification.
+ *Note The Start-Symbol: Start Decl.
+
+Symbol table
+ A data structure where symbol names and associated data are stored
+ during parsing to allow for recognition and use of existing
+ information in repeated uses of a symbol. *Note Multi-function
+ Calc::.
+
+Token
+ A basic, grammatically indivisible unit of a language. The symbol
+ that describes a token in the grammar is a terminal symbol. The
+ input of the Bison parser is a stream of tokens which comes from
+ the lexical analyzer. *Note Symbols::.
+
+Terminal symbol
+ A grammar symbol that has no rules in the grammar and therefore is
+ grammatically indivisible. The piece of text it represents is a
+ token. *Note Languages and Context-Free Grammars: Language and
+ Grammar.
