+
+ * 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.

+
+ 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.

+
+2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Clean up.
+ * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
+ at_directive_argv arguments so these no longer have to be global
+ variables. Also, update the implementation for the following changes.
+ (fail_for_at_directive_too_many_args,
+ fail_for_at_directive_too_few_args): Add at_directive_name argument.
+ (at_directive_name): Remove as at_directive_argv[0] will be used for
+ this now.
+ (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
+ for the directive name.
+ (at_directive_argc, at_directive_argv): Make these local within
+ skel_lex instead of global.
+ (INITIAL): Update directive start action for above changes.
+ (SC_AT_DIRECTIVE_ARG): Rename to...
+ (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
+ (SC_AT_DIRECTIVE_SKIP_WS): Update.
+ (scan_skel): Move yylex_destroy to...
+ (skel_scanner_free): ... here.
+ * tests/skeletons.at (installed skeleton file name): Rename to...
+ (installed skeleton file names): ... this.
+
+2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * ChangeLog: For changes in doc/bison.texinfo, consistently reference
+ node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
+ Summary" not "Directives".
+ * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
+ %code entry in "Decl Summary" rather than the one in "Table of Symbols"
+ since the former is now the more complete one.
+ (Prologue Alternatives): Likewise and do the same for %defines.
+ (Table of Symbols): Add summary of %code, add summary of %define, and
+ move full %code documentation to...
+ (Decl Summary): ... here for consistency with other entries in these
+ sections.
+ Move %define entry in order to keep this list alphabetized.
+ Reword %define entry a little to put less emphasis on the skeleton
+ concept, which most users shouldn't have to think about.
+
+2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
+
+ Adjust to recent gnulib changes.
+ * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
+ Add string.h, string_.h, unistd_.h, wchar_.h.
+ * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
+ * src/system.h: Don't include <stpcpy.h>; this is now done by
+ <string.h>.
+
+2007-01-23 Paolo Bonzini <bonzini@gnu.org>
+
+ Simplify implementation of unqualified %code, implement macros for
+ uniform treatment of boolean %define flags. Document %define.
+ * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,

+
+ * doc/bison.texinfo (Decl Summary): Document %define.

+ b4_percent_code().
+ (content.opt): Default to empty.
+
+2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Implement support for relative and absolute skeleton file names.
+ Discussed starting at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
+ * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
+ (Bison Options): Document in --skeleton entry.
+ * src/output.c (output_skeleton): Use strncpy rather than strcpy since
+ full_skeleton can't necessarily hold all of pkgdatadir.
+ If the specified skeleton file name contains a `/', don't prepend
+ pkgdatadir.
+ * src/parse-gram.y (prologue_declaration): If the specified skeleton
+ file name contains a `/', prepend the grammar file directory.
+ * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
+ * skeletons.at: New file.
+ (relative skeleton file names): New test case.

+
+ * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an

+ Accept "-" standing for stdin.
+ (Calc++ Top Level): Print the result only if the parsing was
+ successful.

+
+2007-01-15 Paolo Bonzini <bonzini@gnu.org>
+ and Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Clean up %define and %code implementation in M4 some. Most
+ importantly, rename all related macros to be in the b4_percent_define
+ and b4_percent_code namespaces. Also, complete support for `.' in
+ %define variable names and %code qualifiers.
+ * data/bison.m4 (b4_check_user_names): Check for special
+ "SKELETON-NAMESPACE(name)" macros instead of using two nested
+ m4_foreach loops.
+ (b4_get_percent_define, b4_get_percent_code): Rename to...
+ (b4_percent_define_get, b4_percent_code_get): ... these.
+ Extend documentation with examples.
+ For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
+ b4_percent_define_skeleton_variables and
+ b4_percent_code_skeleton_qualifiers.
+ Expect any value for the %define variable `foo' to be stored in the
+ macro named `b4_percent_define(foo)'; expect any %code blocks for the
+ qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
+ expect any unqualified %code blocks to be stored in a macro named
+ `b4_percent_code_unqualified'.
+ Use m4_indir so that %define variable names and %code qualifiers can
+ contain `.', which is allowed by the grammar parser.
+ (b4_percent_define_default): New macro to set a default value for a
+ %define variable.
+ (m4_wrap): Update wrapped code, and fix some underquoting.
+ (b4_check_user_names_wrap): Update and define outside the m4_wrap.
+ Expect grammar uses of %define variables and %code qualifiers to be
+ defined in b4_percent_define_user_variables and
+ b4_percent_code_user_qualifiers.
+ * data/c++.m4: Use b4_percent_define_default rather than
+ m4_define_default. Fix some underquoting. Skeleton usage of %define
+ variable define_location_comparison now implies skeleton usage of
+ %define variable filename_type.
+ * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
+ data/push.c, data/yacc.c: Update macro names.
+ * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
+ muscle names.
+
+2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
+
+ DJGPP specific issues.

+ * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
+ default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
+
+2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
+ run parsers in all tests so that Valgrind is invoked during
+ maintainer-check-valgrind.
+ (Duplicate representation of merged trees): Free all semantic values.
+ (Duplicated user destructor for lookahead): Likewise.
+
+2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
+ command-line prefix.
+ * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
+ ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
+ miss Valgrind messages.
+ (Exploding the Stack Size with Malloc): Likewise.
+
+2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
+ locals. Reported by Juan Manuel Guerrero at

+ * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
+ Fix some indentation also.

+ explaining this issue.
+
+2007-01-09 Paolo Bonzini <bonzini@gnu.org>
+ and Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Simplify union and prologue handling, and escape union and lex/parse
+ params with digraphs.
+ * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
+ values to the empty string since these are no longer guaranteed
+ initialized by the front-end.
+ * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
+ braces around b4_user_stype since this is no longer done by the
+ front-end.
+ * src/files.c, src/files.h (pre_prologue_obstack,
+ post_prologue_obstack): Remove.
+ * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
+ comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
+ with digraphs. This fixes lex params and parse params.
+ * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
+ * src/output.c (prepare): Remove muscle insertion of the prologues.
+ (output): Remove freeing of pre_prologue_obstack and
+ post_prologue_obstack.
+ * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
+ than prologue_augment for prologue parsing so you don't need prologue
+ obstacks.
+ (grammar_declaration): For %union RHS, use `braceless' instead of
+ "{...}" so that braces are already stripped and code is escaped with
+ digraphs.
+ * src/reader.c (prologue_augment): Remove.
+ (reader): Remove initialization of pre_prologue_obstack and
+ post_prologue_obstack.
+ * src/reader.h (prologue_augment): Remove.
+
+ * data/c.m4: Remove stray parenthesis.
+
+2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Remove quotes from variables names in %define directives and from
+ qualifiers in %code directives, and restrict the characters that are
+ allowed in them to M4-friendly ones. For %define, continue to support
+ the quoted form as a deprecated feature. Discussed starting at
+ <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
+ * NEWS (2.3a+): Add entry for the change to %define. Update entry for
+ %code.
+ * doc/bison.texinfo (Prologue Alternatives): Update.
+ (Bison Declaration Summary): In %defines entry, update mention of
+ `%code requires' and `%code provides'.
+ (C++ Location Values): Update %define uses.
+ (Calc++ Parser Interface): Likewise.
+ (Calc++ Parser): Likewise, and update `%code requires' uses.
+ (Table of Symbols): Update %code documentation.
+ * src/parse-gram.y (prologue_declaration): For %define variables, use
+ `variable' instead of `STRING'.
+ (grammar_declaration): For %code qualifiers, use `ID' instead of
+ `STRING'.
+ (variable): New nonterminal that takes an `ID' or a `STRING'.
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
+ and %define uses.
+ * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
