+
+ Finer input type for yytranslate.
+ This patch is debatable: the tradition expects yylex to return an int
+ which happens to correspond to token_number (which is an enum). This
+ allows for instance to return characters (such as '*' etc.). But this
+ goes against the stronger typing I am trying to have with the new

+ Introduce make_symbol.
+ make_symbol provides a means to construct a full symbol (kind, value,

+ not work well in C++ (unless the parameter also appears as an argument,
+ which is not acceptable), hence the use of a function instead of a
+ constructor.

+ 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.

+ 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

+ * 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.

+ * data/lalr1.cc (b4_lhs_value, b4_lhs_location): Adjust to using
+ yylhs.
+ (parse): Replace yyval and yyloc with yylhs.value and
+ yylhs.location.
