+
+ Use the new code_props interface in parse-gram.y.
+ * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
+ Update all uses of translate_* functions to use the new code_props
+ interface and to use gram_scanner_last_string_free and
+ code_scanner_last_string_free where possible.
+ (grammar_declaration): symbol_list_destructor_set and
+ symbol_list_printer_set now perform the translation, so don't do it
+ here. Use gram_scanner_last_string_free where possible.
+ * src/scan-code.h, src/scan-code.l (translate_symbol_action,
+ translate_code): Remove, no longer used.
+ * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
+ symbol_list_printer_set): Perform code translation here rather than
+ depending on the caller to do so.
+
+ * src/symlist.h (struct symbol_list): Correct some documentation typos.
+ * src/scan-gram.h (gram_last_string): Remove declaration.
+ * src/scan-gram.l (last_string): Declare it static.

+
+ Encapsulate code properties and related functionality for the various
+ destructors, printers, and actions into a code_props structure and
+ interface. This patch merely implements code_props in scan-code.h and
+ scan-code.l. Future patches will rewrite other modules to use it.
+ Discussed starting at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
+ * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
+ consistently initialize const structs that have an empty location
+ field.
+ * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
+ to ensure consistency.
+ * src/scan-code.h (code_props): New structure.
+ (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
+ function, macro, and const global variable for initializing a
+ code_props with no code.
+ (code_props_plain_init, code_props_symbol_action_init,
+ code_props_rule_action_init, code_props_translate_code): The rest of
+ the new code_props functional interface. Among other things, the init
+ functions set the code_props kind field so that
+ code_props_translate_code will know whether to behave like
+ translate_symbol_action, translate_rule_action, or translate_code.
+ These old translate functions must remain until all other modules are
+ updated to use the new code_props interface.
+ (code_scanner_last_string_free): New function similar to
+ gram_scanner_last_string_free.
+ (code_scanner_free): Add documentation.
+ * src/scan-code.l: Implement the new interface.
+ (code_lex): Make it static, add a code_props* argument, and remove the
+ rule argument.
+ (last_string): New static global similar to the one in scan-gram.l.
+ (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
+ instead of rule.
+ (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
+ code_props since Bison may one day use this information for destructors
+ and printers.
+ (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
+ (handle_action_dollar): Use symbol_list_n_get and set used flag
+ directly since symbol_list_n_used_set is removed.
+ (translate_action): Add a code_props* argument and remove the rule,
+ action, and location arguments. Pass the code_props* on to code_lex.
+ (translate_rule_action, translate_symbol_action, translate_code):
+ Rewrite as wrappers around the new code_props interface.
+ * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
+ it would eventually need to break the encapsulation of code_props.
