+
+	Handle semantic value and location together.
+	* data/lalr1.cc (b4_symbol_actions): Bounce $$ and @$ to
+	yydata.value and yydata.location.
+	(yy_symbol_value_print_, yy_symbol_print_, yydestruct_)
+	(YY_SYMBOL_PRINT): Now take semantic value and location as a
+	single arg.
+	Adjust all callers.
+	(yydestruct_): New overload for a stack symbol.
+
+2008-11-09  Akim Demaille  <demaille@gostai.com>
+
+	Push a complete symbol, not connected parts.
+	* data/lalr1.cc (yypush_): Take a data_type&, not disconnected
+	state, value and location.
+	Adjust callers.
+
+2008-11-09  Akim Demaille  <demaille@gostai.com>
+
+	Agregate yylval and yylloc.
+	* data/lalr1.cc (parser::yylval, parser::yylloc): Replace by...
+	(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.
+	(parser::yy_reduce_print_): Use the state stack.
+
+2008-11-09  Akim Demaille  <demaille@gostai.com>
+
+	Fuse yyval and yyloc into yylhs.
+	* data/lalr1.cc (b4_lhs_value, b4_lhs_location): Adjust to using
+	yylhs.
+	(parse): Replace yyval and yyloc with yylhs.value and
+	yylhs.location.
+	After a user action, compute yylhs.state earlier.
+	(yyerrlab1): Do not play tricks with yylhs.location, rather, use a
+	fresh error_token.
+
+2008-11-09  Di-an Jan  <dianj@freeshell.org>
+
+	Remove unused variable.
+	* src/output.c (type_names_output): Remove unused variable sep.
+
+2008-11-09  Paolo Bonzini  <bonzini@gnu.org>
+
+	Change tests/output.at quoting.

+	expanding arguments.
