+
+ Miscellaneous %define and %code cleanup.
+ * data/bison.m4 (b4_percent_define_flag_if): Correct comments on how
+ values are interpreted.
+ * doc/bison.texinfo (Decl Summary): Clean up and extend %define
+ documentation a little more.
+ * src/muscle_tab.c (MUSCLE_USER_NAME_CONVERT,
+ muscle_percent_define_insert, muscle_percent_code_grow): New
+ functions/macros.
+ * src/muscle_tab.h (muscle_percent_define_insert,
+ muscle_percent_code_grow): Prototype.
+ * src/parse-gram.y (prologue_declaration): Use
+ muscle_percent_define_insert and muscle_percent_code_grow when parsing
+ %define and %code directives.
+
+ Make it easy to share %define boolean variables between the front-end
+ and back-end. Though not used yet, this will be useful in the future.
+ * data/bison.m4 (b4_check_user_names): Rewrite comments to talk about
+ Bison uses of names rather than just skeleton uses of names.
+ (b4_percent_define_get, b4_percent_define_ifdef): Rename
+ b4_percent_define_skeleton_variables(VARIABLE) to
+ b4_percent_define_bison_variables(VARIABLE).
+ (b4_percent_code_get, b4_percent_code_ifdef): Rename
+ b4_percent_code_skeleton_qualifiers(QUALIFIER) to
+ b4_percent_code_bison_qualifiers(QUALIFIER).
+ (b4_check_user_names_wrap): Update for renames.
+ * src/muscle_tab.c, src/muscle_tab.h (muscle_percent_define_flag_if,
+ muscle_percent_define_default): New functions mimicking
+ b4_percent_define_flag_if and b4_percent_define_default.
+
+ For %define variables, report locations for invalid values and
+ redefinitions.
+ * data/bison.m4 (b4_percent_define_flag_if): Read
+ b4_percent_define_loc(VARIABLE) to report the location of an invalid
+ value for VARIABLE.
+ (b4_percent_define_default): Save a special location in
+ b4_percent_define_loc(VARIABLE) in case the default value for VARIABLE
+ must later be reported as invalid.
+ * src/muscle_tab.c (muscle_location_grow, muscle_location_decode): New
+ functions.
+ (muscle_percent_define_insert): Record the location of VARIABLE in
+ muscle percent_define_loc(VARIABLE), and use it to report the previous
+ location for a redefinition.
+ (muscle_percent_define_flag_if): Update like b4_percent_define_flag_if.
+ (muscle_percent_define_default): Update like b4_percent_define_default.
+ (muscle_grow_user_name_list): Rename to...
+ (muscle_user_name_list_grow): ... this for consistency and use
+ muscle_location_grow.
+ * src/muscle_tab.h (muscle_location_grow): Prototype.
+ * tests/input.at (%define errors): Update expected output.
+ * tests/skeletons.at (%define boolean variables: invalid skeleton
+ defaults): New test case.
+
+2007-02-28 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * src/print.c (lookahead_set, state_default_rule): Remove.
+ (print_reductions): Replace state_default_rule invocation with
+ equivalent use of yydefact, which was computed in token_actions in
+ tables.c.
+ (print_results): Don't allocate lookahead_set.
+
+2007-02-27 Paolo Bonzini <bonzini@gnu.org>
+
+ * data/lalr1.java: Prefix all private members with yy.
+
+2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Use YYFPRINTF instead of fprintf where appropriate. Reported by
+ Sébastien Fricker at
+ <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00035.html>.
+ * THANKS: Add Sébastien Fricker.
+ * data/glr.c, data/push.c, data/yacc.c (yy_reduce_print): Implement.
+ * doc/bison.texinfo (Tracing): Make it clearer that YYFPRINTF must
+ accept a variable number of arguments.
+
+2007-02-19 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * bootstrap: Remove occurrences of .#bootmp from lib/Makefile.
+
+2007-02-13 Juan Manuel Guerrero <juan.guerrero@gmx.de>
+
+ * djgpp/config.bat: Adjustments concerning the use of autoconf 2.61.
+ * djgpp/config.sed: Adjustments concerning the use of autoconf 2.61.
+ * djgpp/config.site: Adjustments concerning the use of autoconf 2.61.
+
+2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
+
+ Undo my 2007-02-07 change, switching back to the c-strcase module
+ introduced in the 2007-02-03 change. Bruno Haible reported that
+ the 2007-02-07 change would be dangerous in Turkish if we add a
+ language whose name contains "i", since "i" is not lowercase "I"
+ in Turkish.
+ * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
+ * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
+ c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
+ * m4/.cvsignore: Remove strcase.m4.
+ * src/getargs.c: Revert 2007-02-07 change, as follows.
+ Include c-strcase.h.
+ (language_argmatch): Use c_strcasecmp rather than strcasecmp.
+
+2007-02-11 Bruno Haible <bruno@clisp.org>
+
+ Enable the Java related testsuite tests when the only Java compiler
+ found is a gcj < 4.3. Discussed at
+ <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
+ * configure.ac (gt_JAVACOMP): Don't specify a target_version.
+
+2007-02-11 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * data/Makefile.am: Update copyright date.
+ * data/push.c (yypull_parse): Report memory exhaustion and return 2 if
+ yypstate_new returns NULL.
+ (yypstate_new): Return NULL if malloc does.
+ * src/reader.c (packgram): Move translation of rule actions from the
+ beginning of packgram to...
+ (check_and_convert_grammar): ... here right before packgram is invoked
+ so it's easier to write more complete comments, and remove redundant
+ code.
+
+2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ As in semantic actions, make @$ in %initial-action, %destructor, and
+ %printer imply %locations.
+ * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
+ scanning @$.
+ * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
+ (@$ in %initial-action implies %locations,
+ @$ in %destructor implies %locations,
+ @$ in %printer implies %locations): ... these new test cases.
+
+2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
+
+ Undo most of the 2007-02-03 change, switching to the strcase module
+ now that gnulib strcase has been fixed.
+ * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
+ * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
+ c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
+ * m4/.cvsignore: Add strcase.m4.
+ * src/getargs.c: Revert 2007-02-03 change, as follows.
+ Don't include c-strcase.h.
+ (language_argmatch): Use strcasecmp rather than c_strcasecmp.
+ strcasecmp has "unspecified behavior" outside the POSIX locale,
+ but it works fine in practice if at least one argument is ASCII,
+ as is the case in Bison.
+
+2007-02-07 Paolo Bonzini <bonzini@gnu.org>
+
+ * tests/java.at: Skip tests if only one of javac/java is present.
+ Reported by Joel E. Denny.
+ * tests/atlocal.in: Adjust copyright years.
+
+2007-02-05 Paolo Bonzini <bonzini@gnu.org>
+
+ * data/lalr1.java (Stack): Work around old verifiers that disallow
+ access to the private fields of an inner class, from the outer class.
+ We can make Stack's fields public because user code doesn't have access
+ to the instance of Stack used by parse(). Reported by Paul Eggert.
+
+2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
+
+ * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
+ the right spot for these files?
+ * bootstrap.conf (gnulib_modules): Add c-strcase.
+ * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
+ c-strncasecmp.c.
+ * src/getargs.c: Include c-strcase.h.
+ (language_argmatch): Use c_strcasecmp rather than strcasecmp,
+ to avoid unspecified behavior.
+
+2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * doc/bison.texinfo (Decl Summary): Correct typo.
+
+2007-01-30 Paolo Bonzini <bonzini@gnu.org>
+
+ * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.
+ Complain if the value does not match empty, "true" or "false".
+ * data/c++.m4: Adjust default definitions of %define variables.
+ * data/java.m4: Adjust default definitions of %define variables.
+ * doc/bison.texinfo (Decl Summary): Adjust the %define entry according
+ to above behavior.
+ * tests/input.at (Boolean %define variables): Test new behavior.
+
