- Encapsulate code properties and related functionality for the various
- destructors, printers, and actions into a code_props structure and
- interface.
- * 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/output.c (symbol_destructors_output, symbol_printers_output):
- Replace with...
- (symbol_code_props_output): ... this to eliminate duplicate code.
- (output_skeleton): Update to use symbol_code_props_output.
- * 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/reader.c: Update to use code_props interface for destructors and
- rule actions.
- * 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,
- code_props_code_get, code_props_location_get,
- code_props_is_value_used): The rest of the new code_props interface.
- (translate_rule_action, translate_symbol_action, translate_code):
- Remove as these are now just special cases within
- code_props_translate_code, which is switched on the code_props kind.
- (code_scanner_last_string_free): New function similar to
- gram_scanner_last_string_free.
- * src/scan-code.l: Implement the new interface.
- (last_string): New static global similar to the one in scan-gram.l.
- (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
- code_props since Bison will one day use this information for
- destructors and printers.
- (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
- (handle_action_dollar): Update to use the code_props interface of rule
- actions. Use symbol_list_n_get and set is_value_used directly since
- symbol_list_n_used_set is removed.
- * src/symlist.h, src/symlist.c (symbol_list): Replace action,
- action_location, and used members with a code_props member, and update
- all uses.
- (symbol_list_n_used_set): Remove since it would need to break the
- encapsulation of code_props.
- (symbol_list_destructor_set, symbol_list_printer_set): Perform code
- translation here rather than depending on the caller to do so.
- * src/symtab.h (symbol, semantic_type): Remove destructor_location and
- printer_location members and change the type of the destructor and
- printer members to code_props.
- (symbol_destructor_location_get, symbol_printer_location_get): Remove
- unneeded.
- (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
- symbol_printer_get, semantic_type_destructor_set,
- semantic_type_printer_set, default_tagged_destructor_set,
- default_tagless_destructor_set, default_tagged_printer_set,
- default_tagless_printer_set): Use code_props in arguments and return
- types in place of const char * and location.
- * src/symtab.c: Update implementation for interface and struct changes.
- (default_tagged_destructor_location,
- default_tagless_destructor_location, default_tagged_printer_location,
- default_tagless_printer_location): Remove since we...
- (default_tagged_destructor, default_tagless_destructor,
- default_tagged_printer, default_tagless_printer): ... change the type
- of these to code_props.
- (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
- code_props members.
- (symbol_print): Use SYMBOL_CODE_PRINT.
-
- * src/scan-gram.h (gram_last_string): Remove declaration.
- * src/scan-gram.l (last_string): Declare it static.
+ * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
+ strange test case titles. Reported by Bob Rossi.
+
+2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
+
+ * TODO: Add pointer to Sylvain Schmitz's work on static detection
+ of potential ambiguities in GLR grammers.
+
+2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
+ `bison ', use m4_index instead of m4_substr since chopping up a string
+ containing M4-special characters causes problems here.
+
+ Fix a couple of bugs related to special characters in user-specified
+ file names, and make it easier for skeletons to compute output file
+ names with the same file name prefix as Bison-computed output file
+ names.
+ * data/glr.cc, data/push.c, data/yacc.c: In @output, use
+ b4_parser_file_name and b4_spec_defines_file instead of
+ @output_parser_name@ and @output_header_name@, which are now redundant.
+ * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
+ b4_parser_file_name, b4_spec_defines_file, and the new
+ @basename(FILENAME@) instead of @output_parser_name@ and
+ @output_header_name@, which inappropriately escaped the file names as
+ C string literals.
+ * src/files.c (all_but_ext): Remove static qualifier.
+ (compute_output_file_names): Move `free (all_but_ext)' to...
+ (output_file_names_free): ... here since all_but_ext is needed later.
+ * src/files.h (all_but_ext): Extern.
+ * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
+ exactly what MUSCLE_INSERT_STRING used to do.
+ (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
+ characters are escaped properly.
+ * src/output.c (prepare): Define muscle file_name_all_but_ext as
+ all_but_ext.
+ For pkgdatadir muscle, maintain previous functionality by using
+ MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
+ is that b4_pkgdatadir is used inside m4_include in the skeletons, so
+ digraphs would never be expanded. Hopefully no one has M4-special
+ characters in his Bison installation path.
+ * src/scan-skel.l: Don't parse @output_header_name@ and
+ @output_parser_name@ anymore since they're now redundant.
+ In @output, use decode_at_digraphs.
+ Parse a new @basename command that invokes last_component.
+ (decode_at_digraphs): New.
+ (BASE_QPUTS): Remove unused.
+ * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
+ (Output file name): New tests.
+
+2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Warn about output files that are generated by the skeletons and that
+ conflict with other output files.
+ * data/glr.c: Don't generate the header file here when glr.cc does.
+ * src/files.c (file_names, file_names_count): New static globals.
+ (compute_output_file_names): Invoke output_file_name_check for files
+ not generated by the skeletons and remove existing checks.
+ (output_file_name_check): New function that warns about conflicting
+ output file names.
+ (output_file_names_free): Free file_names.
+ * src/files.h (output_file_name_check): Declare.
+ * src/scan-skel.l: Invoke output_file_name_check for files generated by
+ the skeletons.
+ * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
+ (Conflicting output files): New tests.
+
+2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
+
+ * doc/bison.texinfo: Fix a couple of typos.
+
+2006-12-08 Bob Rossi <bob@brasko.net>
+
+ * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
+ Rename to...
+ (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
+ update all uses.
+ (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
+ (yypush_parse): Rename yypvars argument to yyps and remove redundant
+ local pv.
+ (yypstate_init, yypush_parse): Declare in Bison-generated header file.
+ * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
+
+2006-12-07 Bob Rossi <bob@brasko.net>
+ and Joel Denny <jdenny@ces.clemson.edu>
+
+ * data/push.c (yypvarsinit): Change return type from void* to struct
+ yypvars*. No longer cast to void* on return.
+ (struct yypvars): Remove yylen since it need not be remembered between
+ yypushparse invocations.
+ (yypushparse): Don't copy between yylen and pv->yylen.
+
+2006-12-05 Bob Rossi <bob@brasko.net>
+
+ * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
+ (yypushparse): Add yynchar, yynlval, yynlloc parameters.
+ (b4_declare_parser_variables): Do not declare yynerrs for push mode.
+ (struct yypvars): Remove b4_declare_parser_variables.
+ (yypvarsinit): Remove init code for removed variables.
+ (global scope): Do not declare b4_declare_parser_variables if
+ push or pure mode.
+ (yypushparse): Add b4_declare_parser_variables.
+ Init new local variables, and remove init code for removed
+ yypvars variables.
+ (yyparse): Delete.
+ * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
+ and yyparse for other modes.
+ (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
+ * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
+ (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
+ (AT_PURE_LEX_IF): True if pure or push parser.
+
