+
+       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.
