+
+ Comment changes.
+ * data/lalr1.cc, data/yacc.c: Fix the description of the
+ yytranslate and yytoknum tables.
+
+2008-11-13 Akim Demaille <demaille@gostai.com>
+
+ Define make_symbol in the header.
+ To reach good performances these functions should be inlined (yet this is
+ to measure precisely). To this end they must be available to the caller.
+
+ * data/lalr1.cc (b4_symbol_constructor_definition_): Qualify
+ location_type with the class name.
+ Since will now be output in the header, declare "inline".
+ No longer use b4_symbol_constructor_specializations, but
+ b4_symbol_constructor_definitions in the header.
+ Don't call it in the *.cc file.
+
+2008-11-13 Akim Demaille <demaille@gostai.com>
+
+ Define yytranslate in the header for lex_symbol.
+ * data/lalr1.cc: Move the invocation of b4_yytranslate_definition
+ into the header file when using %define lex_symbol.
+ (yytranslate_): Declare inline.
+
+2008-11-13 Akim Demaille <demaille@gostai.com>
+
+ Define the constructors of symbol_type in b4_symbol_constructor_definitions.
+ The constructors are called by the make_symbol functions, which a
+ forthcoming patch will move elsewhere. Hence the interest of putting them
+ together.
+
+ The stack_symbol_type does not need to be moved, it is used only by the
+ parser.
+
+ * data/lalr1.cc: Move symbol_type and symbol_base_type
+ constructors into...
+ (b4_symbol_constructor_definitions): here.
+ Adjust.
+
+2008-11-13 Akim Demaille <demaille@gostai.com>
+
+ Make it easier to move the definition of yytranslate_.
+ Forthcoming changes will make it possible to use yytranslate_
+ from outside the parser implementation file.
+
+ * data/lalr1.cc (b4_yytranslate_definition): New.
+ Use it.
+
+2008-11-13 Akim Demaille <demaille@gostai.com>
+
+ Remove useless class specification.
+ * data/lalr1.cc (b4_symbol_constructor_specialization_): No need
+ to refer to the class name to use a type defined by the class for
+ arguments of member functions.
+

+
+ 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
+ lex interface which return a symbol_type. So in this case, feed
+ yytranslate_ with a token_type.
+
+ * data/lalr1.cc (yytranslate_): When in %define lex-symbol,
+ expect a token_type.
+
+2008-11-13 Akim Demaille <demaille@gostai.com>
+
+ Honor lex-params in %define lex_symbol mode.
+ * data/lalr1.cc: Use b4_lex_param.
+
+2008-11-13 Akim Demaille <demaille@gostai.com>
+
+ Simplify names.
+ * src/output.c (symbol_definitions_output): Rename symbol
+ attributes type_name and has_type_name as type and has_type.
+ * data/lalr1.cc: Adjust uses.
+
+2008-11-13 Akim Demaille <demaille@gostai.com>
+
+ Use b4_type_names for the union type.
+ The union used to compute the size of the variant used to iterate over the
+ type of all the symbols, with a lot of redundancy. Now iterate over the
+ lists of symbols having the same type-name.
+
+ * data/lalr1.cc (b4_char_sizeof_): New.
+ (b4_char_sizeof): Use it.
+ Adjust to be called with a list of numbers instead of a single
+ number.
+ Adjust its caller for new-line issues.
+
+2008-11-13 Akim Demaille <demaille@gostai.com>
+
+ Define the "identifier" of a symbol.
+ Symbols may have several string representations, for instance if they
+ have an alias. What I call its "id" is a string that can be used as
+ an identifier. May not exist.
+
+ Currently the symbols which have the "tag_is_id" flag set are those that
+ don't have an alias. Look harder for the id.
+
+ * src/output.c (is_identifier): Move to...
+ * src/symtab.c (is_identifier): here.
+ * src/symtab.h, src/symtab.c (symbol_id_get): New.
+ * src/output.c (symbol_definitions_output): Use it to define "id"
+ and "has_id".
+ Remove the definition of "tag_is_id".
+ * data/lalr1.cc: Use the "id" and "has_id" whereever "tag" and
+ "tag_is_id" were used to produce code.
+ We still use "tag" for documentation.
