+
+ * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
+ of AT_NAME_PREFIX when %name-prefix is not used.
+
+2006-03-12 Akim Demaille <akim@lrde.epita.fr>
+
+ Apply --prefix to C++ skeletons too: they change the namespace.
+ The test suite already exercize these cases.
+ * data/c++.m4 (b4_namespace): New.
+ * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
+ * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
+ * data/yacc.c, data/glr.c: Remove a useless `[]'.
+ * doc/bison.texinfo: Document it.
+ (Option Cross Key): Use @multitable in all formats. It looks
+ nicer, even in TeX outputs.
+ (Rules): Use the same code whatever the output type is.
+ * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
+ (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
+ * tests/calc.at: Use it, instead of hard coding `yy'.

+
+ * TODO: Remove dead items.
+
+2006-03-10 Akim Demaille <akim@lrde.epita.fr>
+
+ * doc/FAQ: Remove, merged into...
+ * doc/bison.texinfo (FAQ): this.
+ * doc/Makefile.am (EXTRA_DIST): Adjust.
+
+2006-03-10 Akim Demaille <akim@lrde.epita.fr>
+
+ * data/c.m4 (b4_token_enum): Always define the enum of tokens,
+ even if empty.
+ * data/lalrl1.cc, data/glr.cc (parser::token_type): New.
+ * doc/bison.texinfo (Calc++ Scanner): Use it.
+
+2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
+
+ Fix two nits reported by twlevo, plus one more that I discovered.
+
+ * src/assoc.h (assoc_to_string): Give a name to the arg, as
+ this is the usual Bison style.
+ * src/location.h (location_print): Likewise.
+
+ * src/reader.h (token_name): Likewise.
+
+2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
+
+ Fix some nits reported by twlevo.
+ * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
+ and "POSIX". Use more-modern syntax for URLs. Mention C++
+ and ask for Java. Don't hardwire OS version numbers. Add
+ copyright notice.
+ * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
+ * src/conflicts.c (solved_conflicts_obstack): Now static.
+
+2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
+ page. Say "you can use it" not "you may use it" as on the web page;
+ we're describing capabilities not granting permission.
+
+2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/glr.c (yyresolveLocations): Rename local variables to avoid
+ shadowing warnings. Use usual patter for iterating through RHS.
+ * tests/glr-regression.at
+ (Uninitialized location when reporting ambiguity):
+ Modify yylex so that it uses its argument, rather than trying
+ to rely on ARGSUSED (which doesn't work for gcc with warnings).
+ const char -> char const.
+
+ * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
+ Don't use tabs inside commands; it messes up 'ps'.
+ Problem reported by twlevo.
+
+2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * tests/glr-regression.at (Uninitialized location when reporting
+ ambiguity): New test case.
+ * data/glr.c (yyresolveLocations): New function, which uses
+ YYLLOC_DEFAULT.
+ (yyresolveValue): Invoke yyresolveLocations before reporting an
+ ambiguity.
+ * doc/bison.texinfo (Default Action for Locations): Note
+ YYLLOC_DEFAULT's usage for ambiguity locations.
+ (GLR Semantic Actions): Cross-reference those notes.
+
+2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * tests/glr-regression.at (Leaked semantic values when reporting
+ ambiguity): Remove unnecessary union and type declarations.
+ (Leaked lookahead after nondeterministic parse syntax error): New test
+ case.
+ * data/glr.c (yyparse): Check for zero stacks remaining before
+ attempting to shift the lookahead so that you don't lose it.
+
+2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
+ * tests/glr-regression.at (Leaked semantic values when reporting
+ ambiguity): New test case.
+ * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
+ yyabort rather than invoking yyFail, which invokes longjmp. Remove the
+ now unnecessary yystackp parameter.
+ (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
+ destructors can be called.
+
+ * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
+ in existing testcases.
+
+2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Don't leak semantic values for parent RHS when a user action cuts the
+ parser, and clean up related code a bit.
+ * tests/glr-regression.at (Leaked merged semantic value if user action
+ cuts parse): Rename to...
+ (Leaked semantic values if user action cuts parse): ... this. Add check
+ for leaked parent RHS values.
+ * data/glr.c (yydestroyGLRState): In debugging output, distinguish
+ between an unresolved state (non-empty chain of semantic options) and
+ an incomplete one (signaled by an empty chain).
+ (yyresolveStates): Document the interface. Move all manipulation of a
+ successfully or unsuccessfully resolved yyGLRState to...
+ (yyresolveValue): ... here so that yyresolveValue always leaves a
+ yyGLRState with consistent data and thus is easier to understand.
+ Remove the yyvalp and yylocp parameters since they are always just
+ taken from the yys parameter. When reporting a discarded merged value
+ in debugging output, note that it is incompletely merged. Document the
+ interface.
+ (yyresolveAction): If resolving any of the RHS states fails, destroy
+ them all rather than leaking them. Thus, as long as user actions are
+ written to clean up the RHS correctly, yyresolveAction always cleans up
+ the RHS of a semantic option. Document the interface.
+
+2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that
+ led to a segmentation fault in GNU Pascal. Problem reported
+ by Waldek Hebisch.
+
+2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
+ mid-rule action inside a nonterminal symbol in order to declare a
+ destructor for its semantic value.
+
+2006-02-16 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/yacc.c [(! defined yyoverflow || YYERROR_VERBOSE) && !
+ YYSTACK_USE_ALLOCA && ! defined YYSTACK_ALLOC && defined
+ __cplusplus && ! defined _STDLIB_H && !
+ ((defined YYMALLOC || defined malloc) && (defined YYFREE ||
+ defined free))]: Include <stdlib.h> rather than rolling our own
+ declarations of malloc and free, to avoid problems with
+ incompatible declarations (using 'throw') C++'s stdlib.h. This
+ should fix Debian bug 340012
+ <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=340012>,
+ reported by Guillaume Melquiond.
+
2006-02-13 Paul Eggert <eggert@cs.ucla.edu>
+ * NEWS: Clarify symbols versus types in unused-value warnings.
+
* configure.ac (AC_INIT): Bump version number.
