+@cindex conflicts
+@cindex shift/reduce conflicts
+
+In some grammars, there will be cases where Bison's standard LALR(1)
+parsing algorithm cannot decide whether to apply a certain grammar rule
+at a given point.  That is, it may not be able to decide (on the basis
+of the input read so far) which of two possible reductions (applications
+of a grammar rule) applies, or whether to apply a reduction or read more
+of the input and apply a reduction later in the input.  These are known
+respectively as @dfn{reduce/reduce} conflicts (@pxref{Reduce/Reduce}),
+and @dfn{shift/reduce} conflicts (@pxref{Shift/Reduce}).
+
+To use a grammar that is not easily modified to be LALR(1), a more
+general parsing algorithm is sometimes necessary.  If you include
+@code{%glr-parser} among the Bison declarations in your file
+(@pxref{Grammar Outline}), the result will be a Generalized LR (GLR)
+parser.  These parsers handle Bison grammars that contain no unresolved
+conflicts (i.e., after applying precedence declarations) identically to
+LALR(1) parsers.  However, when faced with unresolved shift/reduce and
+reduce/reduce conflicts, GLR parsers use the simple expedient of doing
+both, effectively cloning the parser to follow both possibilities.  Each
+of the resulting parsers can again split, so that at any given time,
+there can be any number of possible parses being explored.  The parsers
+proceed in lockstep; that is, all of them consume (shift) a given input
+symbol before any of them proceed to the next.  Each of the cloned
+parsers eventually meets one of two possible fates: either it runs into
+a parsing error, in which case it simply vanishes, or it merges with
+another parser, because the two of them have reduced the input to an
+identical set of symbols.
+
+During the time that there are multiple parsers, semantic actions are
+recorded, but not performed.  When a parser disappears, its recorded
+semantic actions disappear as well, and are never performed.  When a
+reduction makes two parsers identical, causing them to merge, Bison
+records both sets of semantic actions.  Whenever the last two parsers
+merge, reverting to the single-parser case, Bison resolves all the
+outstanding actions either by precedences given to the grammar rules
+involved, or by performing both actions, and then calling a designated
+user-defined function on the resulting values to produce an arbitrary
+merged result.
+
+Let's consider an example, vastly simplified from C++.  
+
+@example

+  #define YYSTYPE const char*
+%@}
+

+

+     | TYPENAME declarator '=' expr ';'
+			@{ printf ("%s <init-declare> ", $1); @}
+     ;
+
+declarator : ID		@{ printf ("\"%s\" ", $1); @}
+     | '(' declarator ')'
+     ;
+@end example
+
+@noindent
+This models a problematic part of the C++ grammar---the ambiguity between
+certain declarations and statements.  For example,
+
+@example
+T (x) = y+z;
+@end example
+
+@noindent
+parses as either an @code{expr} or a @code{stmt}
+(assuming that @samp{T} is recognized as a TYPENAME and @samp{x} as an ID).
+Bison detects this as a reduce/reduce conflict between the rules
+@code{expr : ID} and @code{declarator : ID}, which it cannot resolve at the 
+time it encounters @code{x} in the example above.  The two @code{%dprec} 
+declarations, however, give precedence to interpreting the example as a 
+@code{decl}, which implies that @code{x} is a declarator.
+The parser therefore prints
+
+@example
+"x" y z + T <init-declare> 
+@end example
+
+Consider a different input string for this parser:
+
+@example
+T (x) + y;
+@end example
+
+@noindent
+Here, there is no ambiguity (this cannot be parsed as a declaration).
+However, at the time the Bison parser encounters @code{x}, it does not
+have enough information to resolve the reduce/reduce conflict (again,
+between @code{x} as an @code{expr} or a @code{declarator}).  In this
+case, no precedence declaration is used.  Instead, the parser splits
+into two, one assuming that @code{x} is an @code{expr}, and the other
+assuming @code{x} is a @code{declarator}.  The second of these parsers
+then vanishes when it sees @code{+}, and the parser prints
+
+@example
+x T <cast> y + 
+@end example
+
+Suppose that instead of resolving the ambiguity, you wanted to see all
+the possibilities.  For this purpose, we must @dfn{merge} the semantic
+actions of the two possible parsers, rather than choosing one over the
+other.  To do so, you could change the declaration of @code{stmt} as
+follows:
+
+@example
+stmt : expr ';'  %merge <stmtMerge>
+     | decl      %merge <stmtMerge>
+     ;
+@end example
+
+@noindent
+
+and define the @code{stmtMerge} function as:
+
+@example
+static YYSTYPE stmtMerge (YYSTYPE x0, YYSTYPE x1)
+@{
+  printf ("<OR> ");
+  return "";
+@}
+@end example
+
+@noindent
+with an accompanying forward declaration
+in the C declarations at the beginning of the file:
+
+@example
+%@{
+  #define YYSTYPE const char*
+  static YYSTYPE stmtMerge (YYSTYPE x0, YYSTYPE x1);
+%@}
+@end example
+
+@noindent
+With these declarations, the resulting parser will parse the first example
+as both an @code{expr} and a @code{decl}, and print
+
+@example
+"x" y z + T <init-declare> x T <cast> y z + = <OR>

+
+Bison produces @emph{deterministic} parsers that choose uniquely 
+when to reduce and which reduction to apply 
+based on a summary of the preceding input and on one extra token of lookahead.
+As a result, normal Bison handles a proper subset of the family of
+context-free languages.
+Ambiguous grammars, since they have strings with more than one possible 
+sequence of reductions cannot have deterministic parsers in this sense.
+The same is true of languages that require more than one symbol of
+lookahead, since the parser lacks the information necessary to make a
+decision at the point it must be made in a shift-reduce parser.
+Finally, as previously mentioned (@pxref{Mystery Conflicts}), 
+there are languages where Bison's particular choice of how to
+summarize the input seen so far loses necessary information.
+
+When you use the @samp{%glr-parser} declaration in your grammar file,
+Bison generates a parser that uses a different algorithm, called
+Generalized LR (or GLR).  A Bison GLR parser uses the same basic
+algorithm for parsing as an ordinary Bison parser, but behaves
+differently in cases where there is a shift-reduce conflict that has not
+been resolved by precedence rules (@pxref{Precedence}) or a 
+reduce-reduce conflict.  When a GLR parser encounters such a situation, it
+effectively @emph{splits} into a several parsers, one for each possible 
+shift or reduction.  These parsers then proceed as usual, consuming
+tokens in lock-step.  Some of the stacks may encounter other conflicts
+and split further, with the result that instead of a sequence of states, 
+a Bison GLR parsing stack is what is in effect a tree of states.  
+
+In effect, each stack represents a guess as to what the proper parse
+is.  Additional input may indicate that a guess was wrong, in which case
+the appropriate stack silently disappears.  Otherwise, the semantics
+actions generated in each stack are saved, rather than being executed 
+immediately.  When a stack disappears, its saved semantic actions never
+get executed.  When a reduction causes two stacks to become equivalent, 
+their sets of semantic actions are both saved with the state that
+results from the reduction.  We say that two stacks are equivalent
+when they both represent the same sequence of states, 
+and each pair of corresponding states represents a
+grammar symbol that produces the same segment of the input token
+stream.
+
+Whenever the parser makes a transition from having multiple
+states to having one, it reverts to the normal LALR(1) parsing
+algorithm, after resolving and executing the saved-up actions.
+At this transition, some of the states on the stack will have semantic
+values that are sets (actually multisets) of possible actions.  The
+parser tries to pick one of the actions by first finding one whose rule
+has the highest dynamic precedence, as set by the @samp{%dprec}
+declaration.  Otherwise, if the alternative actions are not ordered by 
+precedence, but there the same merging function is declared for both
+rules by the @samp{%merge} declaration, 
+Bison resolves and evaluates both and then calls the merge function on
+the result.  Otherwise, it reports an ambiguity.
+
+It is possible to use a data structure for the GLR parsing tree that
+permits the processing of any LALR(1) grammar in linear time (in the
+size of the input), any unambiguous (not necessarily LALR(1)) grammar in
+quadratic worst-case time, and any general (possibly ambiguous) 
+context-free grammar in cubic worst-case time.  However, Bison currently
+uses a simpler data structure that requires time proportional to the
+length of the input times the maximum number of stacks required for any
+prefix of the input.  Thus, really ambiguous or non-deterministic
+grammars can require exponential time and space to process.  Such badly
+behaving examples, however, are not generally of practical interest.
+Usually, non-determinism in a grammar is local---the parser is ``in
+doubt'' only for a few tokens at a time.  Therefore, the current data
+structure should generally be adequate.  On LALR(1) portions of a
+grammar, in particular, it is only slightly slower than with the default
+Bison parser.
