+
+ * data/glr.c (YYRECOVERING): Define to be a function-like macro
+ with no arguments, not as an object-like macro. This is for
+ compatibility with data/yacc.c. Problem reported by John P. Hartmann in
+ <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
+ * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
+ Document this.
+
+2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * src/getargs.c (usage): Back out yesterday's modification of the
+ --help output so that we don't have to wait for translation before
+ releasing 2.3.
+
+2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
+
+ * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
+ Problem reported by Akim Demaille.
+
+2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
+
+2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/yacc.c (yy_reduce_print): Omit trailing white space in
+ generated source code. Problem reported by Frans Englich in
+ <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
+
+2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
+
+ * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
+ shell, not within 'make', so that 'make' by an ordinary builder
+ (using GNU make) does not worry about configuring gzip. This also
+ works around a bug reported independently by Keith Thompson and by
+ Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
+ stderr rather than stdout, messing up the build logs.
+
+2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
+ to make sure that YYID will never be unused. This fixes a 'make
+ maintainer-check' failure caused by the recent changes to the 'Trivial
+ grammars' test case, which caused g++ 4.1.0 to complain that YYID was
+ not used.
+ * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
+
+2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
+ state before an empty RHS is always resolved here. Only the location
+ of that state is guaranteed to be resolved, and that's enough. This
+ fixes the remaining bug reported by Derek M. Jones in
+ <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
+ * tests/glr-regression.at (Uninitialized location when reporting
+ ambiguity): Test the above case.
+ Also, the embedded comments in this test case claim it checks the case
+ of an empty RHS that has inherited the initial location. However, the
+ corresponding LHS was already resolved, so yyresolveLocations didn't
+ actually have reason to modify it. Fix this by forcing
+ nondeterministic operation at the beginning of the parse.
+
+2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/c.m4 (b4_yy_symbol_print_generate):
+ (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
+ 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
+ of the bugs reported today by Derek M Jones in
+ <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
+ * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
+ defined to be a type name without parens or brackets.
+ (Location Type): Similarly for YYLTYPE.
+ * tests/regression.at (Trivial grammars): Put in a test for this
+ bug that will be caught by 'make maintainer-check' (though not,
+ alas, by 'make check' unless your compiler is picky).
+
+2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
+
+ * NEWS: Version 2.2.
+ * configure.ac (AC_INIT): Likewise.
+
+2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * data/glr.c (yyreportTree): Make room in yystates for the state
+ preceding the RHS. This fixes the segmentation fault reported by Derek
+ M. Jones in
+ <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
+ (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
+ to the user. Reported for yyreportTree by Derek M. Jones later in the
+ same thread.
+ * THANKS: Add Derek M. Jones.
+ Update my email address.
+ Fix typo in Steve Murphy's name.
+
+2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
+ checking against YYLAST that caused the parser to miss a potential
+ alternative in its diagnostic.
+ Problem reported by Maria Jose Moron Fernandez in
+ <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
+ * data/lalr1.cc (yysyntax_error_): Likewise.
+ * data/yacc.c (yysyntax_error): Likewise.
+ * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
+ tokens, in case we run into an older C compiler.
+ (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
+ Use them to check for the off-by-one error fixed above.
+
+ * data/yacc.c (yytnamerr): Fix typo: local var should be of type
+ YYSIZE_T, not size_t.
+ * tests/regression.at (Trivial grammars): New test, to catch
+ the error fixed by the above patch.
+
+2006-05-14 Akim Demaille <akim@lrde.epita.fr>
+
+ * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
+ scheme.
+ Reported by Steve Murphy.
+
+2006-05-14 Akim Demaille <akim@lrde.epita.fr>
+
+ * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
+ * data/glr.cc: b4_location_flag is now b4_locations_flag.
+
+2006-05-14 Akim Demaille <akim@lrde.epita.fr>
+
+ Implement --trace=m4.
+ * src/getargs.c (trace_types, trace_args): Accept trace_m4.
+ * src/output.c (output_skeleton): When set, pass -dV to m4.
+
+ Factor the handling of flags in m4.
+ * src/output.c (prepare): Rename the muscle names debug, defines,
+ error_verbose to debug_flag, defines_flag, error_verbose_flag.
+ * data/c.m4: Adjust.
+ (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
+ Use b4_define_flag_if to define other b4_FLAG_if macros.
+ (b4_location_if): As a consequence, rename as...
+ (b4_locations_if): this, for consistency.
+ Adjust all the skeletons.
+
+2006-05-14 Akim Demaille <akim@lrde.epita.fr>
+
+ * etc/bench.pm: Shorten bench names.
+
+2006-05-14 Akim Demaille <akim@lrde.epita.fr>
+
+ * src/output.h, src/output.c (error_verbose): Move to...
+ * src/getargs.h, src/getargs.c: here.
+ Sort the flags.
+ Adjust dependencies.
+
+2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/c.m4 (b4_copyright): Put the special exception for Bison
+ skeletons here, so we don't have to put it in each skeleton. All
+ uses changed. Suggested by Akim Demaille. Also, wrap the
+ copyright notice, in case it is longer than 80 columns. Replace
+ comma by newline after title.
+
+2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
+
+ * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
+ incompatibility, not a bug. Mention that it wasn't fixed as of
+ flex 2.5.33.
+
+2006-05-11 Akim Demaille <akim@lrde.epita.fr>
+
+ * examples/extexi: Enforce the precedence of concatenation over
+ >>.
+ Reported by Tommy Nordgren.
+
2006-05-11 Akim Demaille <akim@lrde.epita.fr>
* data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
with the member "token".
Reported by Martin Nylin.
+2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/glr.c: Switch to Bison 2.2 special-exception language in
+ the copyright notice. Use more-regular format for titles and
+ copyright notices.
+ * data/glr.cc: Likewise.
+ * data/location.cc: Likewise.
+ * data/yacc.cc: Likewise.
+ * doc/bison.texinfo (Conditions): Document this.
+ * NEWS: likewise. Upgrade version to 2.2.
+
2006-04-27 Akim Demaille <akim@lrde.epita.fr>
* data/glr.cc: Remove dead code.
