+
+2008-11-10  Akim Demaille  <demaille@gostai.com>
+
+	Formatting changes.
+
+2008-11-10  Akim Demaille  <demaille@gostai.com>

+
+2008-11-10  Akim Demaille  <demaille@gostai.com>
+
+	Change the handling of the symbols in the skeletons.
+	Before we were using tables which lines were the symbols and which
+	columns were things like number, tag, type-name etc.  It is was
+	difficult to extend: each time a column was added, all the numbers had
+	to be updated (you asked for colon $2, not for "tag").  Also, it was
+	hard to filter these tables when only a subset of the symbols (say the
+	tokens, or the nterms, or the tokens that have and external number
+	*and* a type-name) was of interest.
+	
+	Now instead of monolithic tables, we define one macro per cell.  For
+	instance "b4_symbol(0, tag)" is a macro name which contents is
+	self-decriptive.  The macro "b4_symbol" provides easier access to
+	these cells.
+	
+	* src/output.c (type_names_output): Remove.
+	(symbol_numbers_output, symbol_definitions_output): New.
+	(muscles_output): Call them.
+	(prepare_symbols): Define b4_symbols_number.

+2008-11-10  Akim Demaille  <demaille@gostai.com>

+	* src/output.c (output_skeleton): Use it.
+
+2008-11-10  Akim Demaille  <demaille@gostai.com>
+
+	muscles_output.
+	* src/output.c (muscles_output): New, extracted from...
+	(output_skeleton): here.
+	Adjust.
+
+2008-11-10  Akim Demaille  <demaille@gostai.com>
+
+	Formatting changes.

+	One stage build.
+
+2008-11-10  Akim Demaille  <demaille@gostai.com>

+	Use it with and without %define assert.
+
+2008-11-10  Akim Demaille  <demaille@gostai.com>
+
+	Add %precedence support.
+	Unfortunately it is not possible to reuse the %prec directive.  This
+	is because to please POSIX, we do not require to end the rules with a
+	semicolon.  As a result,
+	
+	foo: bar %prec baz
+	
+	is ambiguous: either a rule which precedence is that of baz, or a rule,
+	and then a declaration of the precedence of the token baz.
+	
+	* doc/bison.texinfo: Document %precedence.
+	(Precedence Only): New.
+	* src/assoc.h, src/assoc.c (precedence_assoc): New.

+	(-b, -g): New options.
+
+2008-11-09  Akim Demaille  <demaille@gostai.com>
+
+	Use a static hierarchy for symbols in the C++ parser.
+	* data/lalr1.cc (symbol_base_type, symbol_type)
+	(stack_symbol_type): Make it a static hierarchy.
+	Adjust dependencies.
+
+2008-11-09  Akim Demaille  <demaille@gostai.com>
+
+	bench.pl -d, --directive.
+	* etc/bench.pl.in (@directive): New.
+	(&bench_grammar): Use it.
+	(&bench_list_grammar): New, to provide access to the "variant"
+	grammar.
+	Use it.
+	(getopts): Support -d, --directive.
+
+2008-11-09  Akim Demaille  <demaille@gostai.com>

+	Use its type member instead of yytoken.
+
+2008-11-09  Akim Demaille  <demaille@gostai.com>
+
+	Rename data_type and stack_symbol_type.
+	* data/lalr1.cc (data_type): Rename as...
+	(stack_symbol_type): this.
+
+2008-11-09  Akim Demaille  <demaille@gostai.com>

+	(parser::yyla): this.
+
+2008-11-09  Akim Demaille  <demaille@gostai.com>
+
+	Rely on the state stack to display reduction traces.
+	To display rhs symbols before a reduction, we used information about the rule
+	reduced, which required the tables yyrhs and yyprhs.  Now use rely only on the
+	state stack to get the same information.
+	
+	* data/lalr1.cc (b4_rhs_data, b4_rhs_state): New.
+	Use them.
+	(parser::yyrhs_, parser::yyprhs_): Remove.

+	expanding arguments.
+
+2008-11-07  Joel E. Denny  <jdenny@ces.clemson.edu>

+
+2008-11-07  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	Clean up %skeleton and %language priority implementation.

+	* src/getargs.h (command_line_prio, grammar_prio, default_prio): New
+	enum fields.
+	(skeleton_prio): Extern it.
+	(language_prio): Extern it.

+
+	Avoid empty-if warnings.
+	Reported by Quentin Hocquet.

+	* data/lalr1-fusion.cc (YY_SYMBOL_PRINT, YY_REDUCE_PRINT)
+	(YY_STACK_PRINT): Provide some contents even when !YYDEBUG.
+
+2008-11-07  Akim Demaille  <demaille@gostai.com>
+
+	Pass command line location to skeleton_arg and language_argmatch.
+	* src/getargs.h, src/getargs.c (skeleton_arg, language_argmatch):
+	The location argument is now mandatory.
+	Adjust all dependencies.
+	(getargs): Use command_line_location.
+
+2008-11-07  Akim Demaille  <demaille@gostai.com>
+
+	-D, --define.

+2008-11-07  Akim Demaille  <demaille@gostai.com>
+
+	Initialize the muscle table before parsing the command line.
+	* src/getargs.c (quotearg.h, muscle_tab.h): Include.
+	(getargs): Define file_name.
+	* src/main.c (main): Initialize muscle_tab before calling
+	getargs.
+	* src/muscle_tab.c (muscle_init): No longer define file_name, as
+	its value is not available yet.
+
+2008-11-07  Akim Demaille  <demaille@gostai.com>
+
+	Locations without columns for command line arguments.
+	* src/location.c (location_print): Don't display negative columns.

+2008-11-07  Akim Demaille  <demaille@gostai.com>
+
+	Handle more general types of option arguments.
+	* build-aux/cross-options.pl: The argument ends at the first
+	space, not the first non-symbol character.

+
+2008-11-07  Akim Demaille  <demaille@gostai.com>
+
+	Destroy the variants that remain on the stack in case of error.
+	* data/lalr1-fusion.cc (yydestruct_): Invoke the variant's
+	destructor.

+
+2008-11-07  Akim Demaille  <demaille@gostai.com>
+
+	Add "%define assert" to variants.
+	This is used to help the user catch cases where some value gets
+	ovewritten by a new one.  This should not happen, as this will
+	probably leak.
+	
+	Unfortunately this uncovered a bug in the C++ parser itself: the
+	lookahead value was not destroyed between two calls to yylex.  For
+	instance if the previous lookahead was a std::string, and then an int,
+	then the value of the std::string was correctly taken (i.e., the
+	lookahead was now an empty string), but std::string structure itself
+	was not reclaimed.
+	
+	This is now done in variant::build(other&) (which is used to take the
+	value of the lookahead): other is not only stolen from its value, it
+	is also destroyed.  This incurs a new performance penalty of a few
+	percent, and union becomes faster again.
+	
+	* data/lalr1-fusion.cc (variant::build(other&)): Destroy other.
+	(b4_variant_if): New.
+	(variant::built): New.
+	Use it whereever the status of the variant changes.
+	* etc/bench.pl.in: Check the penalty of %define assert.
+
+2008-11-07  Akim Demaille  <demaille@gostai.com>
+
+	Use "%define variant" in bench.pl.
+	* etc/bench.pl.in: No longer use the pseudo directive %variants,
+	just use %define variants.
+
+2008-11-07  Akim Demaille  <demaille@gostai.com>
+
+	Regen.
+	* src/parse-gram.h, src/parse-gram.c: Regen.
+
+2008-11-04  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+	Fix user actions without a trailing semicolon.
+	Reported by Sergei Steshenko at
+	<http://lists.gnu.org/archive/html/bug-bison/2008-11/msg00001.html>.
+	* THANKS (Sergei Steshenko): Add.
+	* src/scan-code.l (SC_RULE_ACTION): Fix it.
+	* tests/regression.at (Fix user actions without a trailing semicolon):
+	New test case.
+
+2008-11-04  Akim Demaille  <demaille@gostai.com>
+
+	Use b4_copyright_years.
