3 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
4 unreliable -- especially when they're hidden inside another macro.
5 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
6 data/c.m4: Remove m4_divert(-1).
7 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
8 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
9 m4_divert_push(0) and m4_divert_pop(0).
10 * data/output.c (output_skeleton): Don't add an m4_divert_push(0) and
11 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
12 pushed and popped by m4sugar, should be first on the stack.
14 Provide warn, complain, and fatal function callbacks to the skeletons.
15 This provides more flexibility than m4_fatal, improves the error
16 message format, and captures messages for translation. Discussed
18 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
19 * data/bison.m4 (b4_error): New, invoked by...
20 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
21 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
22 directives. Because these M4 macros might be called when the current
23 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
24 the previous removal of uses of m4_divert, which caused trouble.
25 (b4_check_percent_code_qualifiers): Use b4_complain instead of
26 m4_fatal to report unrecognized %code qualifiers.
27 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
29 * data/glr.c: Use b4_complain instead of m4_fatal to report
30 non-deterministic push parser requests.
31 Update @output usage to @output(...@) form.
32 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
33 report missing %defines. Update @output usage to @output(...@) form.
34 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
36 * src/main.c (main): Invoke skel_scanner_free.
37 * src/scan-skel.h (skel_scanner_free): Prototype new function.
38 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
39 obstack_for_string from flex-scanner.h.
40 (YY_DECL): Use to declare skel_lex static.
41 (decode_at_digraphs): Remove; now handled in the new
42 SC_AT_DIRECTIVE_ARG start condition.
43 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
45 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
46 at_directive_argv): New static globals.
47 (INITIAL): Use fail_for_invalid_at.
48 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
49 recognize the start of a generalized `@directive(...@)' form and
51 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
52 directive args (using the new obstack_for_string), to decode the
53 contained @ diagraphs, and to perform the directive. It recognizes
54 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
56 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
57 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
59 (scan_skel): Initialize obstack_for_string on the first call.
60 (skel_scanner_free): New function to free obstack_for_string.
61 * tests/input.at (Reject bad %code qualifiers): Update test output.
63 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
65 Consolidate the 4 prologue alternative directives (%code, %requires,
66 %provides, and %code-top) into a single %code directive with an
67 optional qualifier field. Discussed at
68 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
69 * NEWS (2.3a+): Rewrite the existing entry for the prologue
71 * doc/bison.texinfo (Prologue Alternatives): Update.
72 (Decl Summary): Update to %code "requires" and %code "provides".
73 (Calc++ Parser): Update to %code "requires".
74 (Bison Symbols): Remove entries for %requires, %provides, and
75 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
76 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
77 are replaced by b4_percent_code_provides and b4_percent_code_requires,
78 which are skeleton-specific.
79 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
80 declare what %code qualifiers it supports and to complain if any other
81 qualifiers were used in the grammar.
82 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
83 and b4_user_code([b4_percent_code_provides]) in place of
84 b4_user_requires and b4_user_provides.
85 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
86 Add b4_user_code([b4_percent_code_top]) and
87 b4_user_code([b4_percent_code]).
88 Invoke b4_check_percent_code_qualifiers.
89 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
90 PERCENT_REQUIRES): Remove.
91 (grammar_declaration): Remove RHS's for %code-top, %provides, and
92 %requires. Rewrite the %code RHS as the unqualified form defining the
93 muscle b4_percent_code. Add another RHS for the qualified %code form,
94 which defines muscles of the form b4_percent_code_QUALIFIER and the
95 b4_used_percent_code_qualifiers muscle.
96 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
97 PERCENT_REQUIRES): Remove.
98 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
99 %code "requires" and %code "provides".
100 * tests/input.at (Reject bad %code qualifiers): New.
102 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
104 Use the new code_props interface for destructors and printers.
105 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
106 printer_location members, and change the type of the destructor and
107 printer members to code_props.
108 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
109 symbol_printer_get, semantic_type_destructor_set,
110 semantic_type_printer_set, default_tagged_destructor_set,
111 default_tagless_destructor_set, default_tagged_printer_set,
112 default_tagless_printer_set): Use code_props in arguments and return
113 types in place of char const * and location.
114 (symbol_destructor_location_get, symbol_printer_location_get): Remove
115 since the locations are now contained in the return of
116 symbol_destructor_get and symbol_printer_get.
117 * src/output.c (symbol_destructors_output, symbol_printers_output):
119 (symbol_code_props_output): ... this to eliminate duplicate code.
120 (output_skeleton): Update to use symbol_code_props_output.
121 * src/reader.c (symbol_should_be_used): Update use of
122 symbol_destructor_get.
123 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
124 Update uses of the various _destructor_set and _printer_set functions.
125 * src/symtab.c: (default_tagged_destructor_location,
126 default_tagless_destructor_location, default_tagged_printer_location,
127 default_tagless_printer_location): Remove since we...
128 (default_tagged_destructor, default_tagless_destructor,
129 default_tagged_printer, default_tagless_printer): ... change the type
130 of these to code_props.
131 (symbol_new, semantic_type_new, symbol_destructor_set,
132 semantic_type_destructor_set, symbol_destructor_get,
133 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
134 symbol_check_alias_consistency, default_tagged_destructor_set,
135 default_tagless_destructor_set, default_tagged_printer_set,
136 default_tagless_printer_set): Update.
137 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
138 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
140 (symbol_print): Use SYMBOL_CODE_PRINT.
142 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
144 Use the new code_props interface for rule actions.
145 * src/symlist.h (symbol_list): Replace action, action_location, and
146 used members with a code_props action_props member.
147 * src/reader.c (symbol_should_be_used, grammar_rule_check,
148 grammar_midrule_action, grammar_current_rule_merge_set,
149 grammar_current_rule_symbol_append, packgram): Update.
150 * src/scan-code.h (translate_rule_action): Remove, no longer used.
151 * src/scan-code.l (handle_action_dollar): Update.
152 (translate_rule_action): Remove, no longer used.
153 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
155 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
157 Use the new code_props interface in parse-gram.y.
158 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
159 Update all uses of translate_* functions to use the new code_props
160 interface and to use gram_scanner_last_string_free and
161 code_scanner_last_string_free where possible.
162 (grammar_declaration): symbol_list_destructor_set and
163 symbol_list_printer_set now perform the translation, so don't do it
164 here. Use gram_scanner_last_string_free where possible.
165 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
166 translate_code): Remove, no longer used.
167 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
168 symbol_list_printer_set): Perform code translation here rather than
169 depending on the caller to do so.
171 * src/symlist.h (struct symbol_list): Correct some documentation typos.
172 * src/scan-gram.h (gram_last_string): Remove declaration.
173 * src/scan-gram.l (last_string): Declare it static.
175 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
177 Encapsulate code properties and related functionality for the various
178 destructors, printers, and actions into a code_props structure and
179 interface. This patch merely implements code_props in scan-code.h and
180 scan-code.l. Future patches will rewrite other modules to use it.
181 Discussed starting at
182 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
183 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
184 consistently initialize const structs that have an empty location
186 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
187 to ensure consistency.
188 * src/scan-code.h (code_props): New structure.
189 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
190 function, macro, and const global variable for initializing a
191 code_props with no code.
192 (code_props_plain_init, code_props_symbol_action_init,
193 code_props_rule_action_init, code_props_translate_code): The rest of
194 the new code_props functional interface. Among other things, the init
195 functions set the code_props kind field so that
196 code_props_translate_code will know whether to behave like
197 translate_symbol_action, translate_rule_action, or translate_code.
198 These old translate functions must remain until all other modules are
199 updated to use the new code_props interface.
200 (code_scanner_last_string_free): New function similar to
201 gram_scanner_last_string_free.
202 (code_scanner_free): Add documentation.
203 * src/scan-code.l: Implement the new interface.
204 (code_lex): Make it static, add a code_props* argument, and remove the
206 (last_string): New static global similar to the one in scan-gram.l.
207 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
209 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
210 code_props since Bison may one day use this information for destructors
212 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
213 (handle_action_dollar): Use symbol_list_n_get and set used flag
214 directly since symbol_list_n_used_set is removed.
215 (translate_action): Add a code_props* argument and remove the rule,
216 action, and location arguments. Pass the code_props* on to code_lex.
217 (translate_rule_action, translate_symbol_action, translate_code):
218 Rewrite as wrappers around the new code_props interface.
219 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
220 it would eventually need to break the encapsulation of code_props.
222 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
224 * etc/.cvsignore: New.
226 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
228 Add maintainer-push-check to run maintainer-check using push parsing in
229 place of pull parsing where available.
230 * Makefile.am (maintainer-push-check): New.
231 * data/bison.m4 (b4_use_push_for_pull_if): New.
232 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
233 appropriately based on their existing values.
234 (yypush_parse): Don't print push-parser-specific diagnostics if push
235 parsing is being used in place of pull parsing.
236 * data/yacc.c: If push parsing should replace pull parsing, redirect to
238 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
239 variable, and insert b4_use_push_for_pull_flag into muscles.
240 * tests/Makefile.am (maintainer-push-check): New.
242 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
244 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
245 (whether successful or failed) so that yypush_parse can be invoked
246 again to start a new parse using the same yypstate.
247 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
248 check multiple yypull_parse invocations on the same yypstate. For pull
249 mode, extend to check multiple yyparse invocations.
250 (Exploding the Stack Size with Alloca): Extend to try with
252 (Exploding the Stack Size with Malloc): Likewise.
254 * tests/calc.at (Simple LALR Calculator): Don't specify
255 %skeleton "push.c" since %push-pull-parser implies that now.
256 * tests/headers.at (export YYLTYPE): Don't check for the push
257 declarations. Otherwise, this test case can't be used to see if push
258 mode can truly emulate pull mode.
259 * tests/input.at (Torturing the Scanner): Likewise.
260 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
261 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
262 AT_YACC_IF, which now includes the case of push mode since %skeleton
263 need not be used for push mode. This will be more intuitive once
264 push.c is renamed to yacc.c.
266 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
268 For push mode, convert yyparse from a macro to a function, invoke yylex
269 instead of passing a yylexp argument to yypull_parse, and don't
270 generate yypull_parse or yyparse unless %push-pull-parser is declared.
271 Discussed starting at
272 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
273 * data/bison.m4 (b4_pull_if): New.
274 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
275 * data/push.c: Improve M4 quoting a little.
276 (b4_generate_macro_args, b4_parenthesize): Remove.
277 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
278 any time a pull parser is requested.
279 Don't #define this as a wrapper around yypull_parse. Instead, when
280 both push and pull are requested, make it a function that does that
282 (yypull_parse): If there's a b4_prefix, #define this to
283 b4_prefix[pull_parse] when both push and pull are requested.
284 Don't define this as a function unless both push and pull are
286 Remove the yylexp argument and hard-code yylex invocation instead.
287 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
289 * src/getargs.c (pull_parser): New global initialized to true.
290 * getargs.h (pull_parser): extern it.
291 * src/output.c (prepare): Insert pull_flag muscle.
292 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
293 (prologue_declaration): Set both push_parser and pull_parser = true for
294 %push-pull-parser. Set push_parser = true and pull_parser = false for
296 * src/scan-gram.l: Don't accept %push_parser as an alternative to
297 %push-parser since there's no backward-compatibility concern here.
298 Scan %push-pull-parser.
299 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
300 instead of %push-parser.
301 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
302 prototype it in the module that calls yyparse.
303 * tests/input.at (Torturing the Scanner): Likewise.
304 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
306 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
308 Update etc/bench.pl. Optimize push mode a little (the yyn change
309 deserves most of the credit).
310 * Makefile.am (SUBDIRS): Add etc subdirectory.
311 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
312 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
313 yytoken, yyval, and yyloc declarations to...
314 (yyparse or yypush_parse): ... here to improve performance. For
315 yypush_parse invocations after the first, be sure to assign yyn its old
317 (yypstate_new): Don't bother initializing the yyresult field since the
318 initial value isn't used.
319 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
320 remove the #define that, in push mode, set it to yyps->NAME.
321 * etc/Makefile.am: New.
322 * etc/bench.pl: Remove and build it instead from...
323 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
324 "tests/bison" from the build directory by default rather than just
325 invoking "bison" from $PATH.
326 (calc_grammar): Update push parser code: don't declare yylval globally,
327 don't define yyparse_wrapper, and don't #define yyparse.
328 (bench_grammar): Update to check all working combinations of yacc.c,
329 push.c, impure, pure, pull, and push.
331 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
333 For push mode, add pull wrappers around yypush_parse.
334 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
335 (yypull_parse): New function wrapping yypush_parse.
336 (yyparse): New #define wrapping yypull_parse.
337 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
339 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
340 prototype yylex in the module that calls yyparse, and don't prototype
341 yyparse there. Otherwise, the yyparse expansion won't compile.
342 * tests/input.at (Torturing the Scanner): Likewise.
344 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
346 Enable push parsers to operate in impure mode. Thus, %push-parser no
347 longer implies %pure-parser. The point of this change is to move
348 towards being able to test the push parser code by running the entire
349 test suite as if %push-parser had been declared.
350 * data/push.c (yypush_parse): For impure mode, remove the
351 yypushed_char, yypushed_val, and yypushed_loc arguments.
352 Instead, declare these as local variables initialized to the global
353 yychar, yylval, and yylloc.
354 For the first yypush_parse invocation only, restore the initial values
355 of these global variables when it's time to read a token since they
356 have been overwritten.
357 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
359 * tests/calc.at (Simple LALR(1) Calculator): Always declare
360 %pure-parser along with %push-parser since this test case was designed
361 for pure push parsers.
362 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
363 (AT_YACC_OR_PUSH_IF): New.
364 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
365 add a note that it's still wrong for some cases (as it has been for a
367 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
368 %push-parser no longer implies %pure-parser.
370 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
372 Remove some unnecessary differences between the pull parser code and
373 the push parser code. This patch enables yynerrs in push mode.
374 * data/push.c: Reformat M4 a little.
375 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
376 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
377 because push mode is on. Instead, if pure mode is on, move yynerrs
379 (b4_declare_parser_state_variables): ... here.
380 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
381 to yyps->NAME so it can be used in yypush_parse.
382 (yypush_parse): Don't omit uses of yynerrs in push mode.
384 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
386 Fix bug such that the first pushed token's value and location are
387 sometimes overwritten (sometimes by %initial-action) before being used.
388 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
389 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
390 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
391 more closely mimic the pull parser logic.
392 Don't copy the pushed token to yychar, yylval, and yylloc until it's
393 time to read a token, which is after any initialization of yylval and
395 (gottoken): Rename label to...
396 (yyread_pushed_token): ... for clarity and to avoid infringing on the
399 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
401 Rearrange initialization of the parser state variables so that the
402 skeleton doesn't have to have a copy for pull mode and another for push
403 mode. This patch also fixes at least a bug such that yylloc was not
404 initialized (with b4_location_initial_line and
405 b4_location_initial_column) upon calling yypush_parse. However, that
406 initialization now overwrites the first token's location;
407 %initial-action assigning @$ already did the same thing, and both bugs
408 will be fixed in a later patch.
409 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
410 (b4_declare_parser_state_variables): Remove initialization of yytoken,
411 yyss, yyvs, yyls, and yystacksize.
412 (yypstate_new): Remove initialization of some yypstate fields: yystate,
413 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
415 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
416 yyps->NAME so it can be used in yypush_parse.
417 (yyparse or yypush_parse): For yypush_parse, don't print the
418 "Starting parse" diagnostic for invocations after the first.
419 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
420 yypush_parse, only do it for the first invocation.
421 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
422 initialization to occur in yypush_parse but only on the first
425 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
427 * data/push.c: Add CPP guards around push parser declarations in both
428 the header and the code file.
429 In the code file, move the push parser declarations to the same place
430 they appear in the header file.
431 Clean up the M4 some, especially the inconsistent underquoting in
432 some b4_c_function_def and b4_c_function_decl uses.
434 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
436 Encapsulate the push parser state variables into an M4 macro so the
437 push skeleton doesn't have to list them again for pull mode's yyparse.
438 For push mode, remove yypush_parse's local equivalents of these
439 variables to eliminate unnecessary copying between the two sets at
440 run-time. This patch also fixes at least a bug related to multiple
441 %initial-action invocations in push mode.
442 * data/push.c (b4_declare_parser_variables): Rename to...
443 (b4_declare_scanner_communication_variables): ... this for clarity and
445 (b4_declare_yyparse_variables): Remove and move its contents to the one
446 spot where it was invoked.
447 (b4_declare_parser_state_variables): New macro containing the parser
448 state variables required by push mode.
449 (struct yypstate): Replace all fields but yynew with
450 b4_declare_parser_state_variables.
451 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
452 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
453 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
454 (yyparse or yypush_parse): For yyparse in pull mode, replace local
455 parser state variable declarations with
456 b4_declare_parser_state_variables.
457 Don't initialize parser state variables when calling yypush_parse since
458 yypstate_new already does that.
459 Invoke the user's initial action only upon the first yypush_parse
461 Remove all code that copies between the local parser state variables
464 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
466 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
467 prevent a name collision in a future patch where these names will
468 sometimes be #define'd.
469 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
470 since it no longer has the same name as the existing argument.
471 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
473 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
474 and Joel E. Denny <jdenny@ces.clemson.edu>
476 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
477 that the argument is case-insensitive, and there's no `=' here.
478 For the %skeleton entry, mention that %language is better.
479 (Bison Options): Likewise for --language and --skeleton. Move the
480 --skeleton entry so that the `Tuning the parser' section is sorted
481 alphabetically on long options.
482 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
483 %language directive in detail here; cross-reference the %language
484 documentation instead.
485 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
486 `%require "2.3b"' so that the example is always up-to-date.
487 (Bison Symbols): Add entries for %language and %skeleton.
488 * examples/extexi (normalize): Instead of replacing every %require
489 argument with the current Bison version, just substitute for
490 `@value{VERSION}'. This guarantees that we're testing what actually
491 appears in the documentation.
492 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
493 rather than `@VERSION@'.
495 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
497 * NEWS: Reword the %language news a bit, and put it earlier.
499 * src/getargs.c (skeleton_arg): Last arg is now location const *.
500 Rewrite to simplify the logic.
501 (language_argmatch): Likewise.
502 (program_name): We now own this var.
503 * src/getargs.h (struct bison_language): Use char[] rather than
506 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
508 * src/complain.c (program_name): Remove decl; no longer needed.
509 * src/main.c (program_name): Remove; now belongs to getargs.
511 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
513 * NEWS: Document %language.
515 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
517 * data/c-skel.m4, data/c++-skel.m4: New files.
518 * data/glr.c: Complain on push parsers.
520 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
522 (Directives): Document %language and %skeleton.
523 (Command line): Document -L.
525 * examples/extexi: Rewrite %require directive.
526 * examples/calc++/Makefile.am: Pass VERSION to extexi.
528 * src/files.c (compute_exts_from_gc): Look in language structure
530 (compute_file_name_parts): Check whether .tab should be added.
531 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
532 (language, skeleton_arg, language_argmatch): New.
533 (long_options): Add --language.
534 (getargs): Use skeleton_arg, add -L/--language.
535 * src/getargs.h: Include location.h.
536 (struct bison_language, language, skeleton_arg, language_argmatch): New.
537 * src/output.c (prepare): Pick default skeleton from struct language.
538 Don't dispatch C skeletons here.
539 * src/parse-gram.y (PERCENT_LANGUAGE): New.
540 (prologue_declaration): Add "%language" rule, use skeleton_arg.
541 * src/scan-gram.l ("%language"): New rule.
543 * tests/calc.at: Test %skeleton and %language.
544 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
545 (AT_GLR_IF): Look for %skeleton "glr.cc".
546 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
547 (AT_YACC_IF): Reject %language.
549 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
551 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
552 since it wasn't used; only the typedef name 'semantic_type' is needed.
553 Also, omit trailing white space.
555 * bootstrap: Sync from coreutils.
556 (gnulib_extra_files): Add build-aux/announce.gen.
557 (slurp): Adjust .gitignore files like .cvsignore files.
558 * build-aux/announce-gen: Remove from CVS, since bootstrap
561 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
563 Make %push-parser imply %pure-parser. This fixes several bugs; see
564 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
565 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
567 * data/push.c: Don't bother testing b4_push_if when deciding whether
568 to expand b4_declare_parser_variables globally.
569 (yypush_parse): Likewise in here.
571 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
572 (yy_reduce_print): Reformat M4 for readability.
574 2006-12-15 Bob Rossi <bob@brasko.net>
575 and Joel Denny <jdenny@ces.clemson.edu>
577 * data/push.c (yypstate): Add typedef, and update all uses of
578 struct yypstate to just yypstate.
579 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
581 2006-12-14 Bob Rossi <bob@brasko.net>
583 * data/push.c (yypush_parse): Declare prototype regardless of
586 2006-12-14 Bob Rossi <bob@brasko.net>
588 * data/push.c (yyparse): Remove the prototype and the #define when in
591 2006-12-13 Bob Rossi <bob@brasko.net>
593 * data/push.c (yypstate_init): Rename to...
594 (yypstate_new): ... this and use b4_c_function_def.
595 (yypstate_delete): New.
596 (yypush_parse): Change parameters yynval and yynlloc to be const.
597 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
598 yypstate_delete functions.
600 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
602 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
603 strange test case titles. Reported by Bob Rossi.
605 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
607 * TODO: Add pointer to Sylvain Schmitz's work on static detection
608 of potential ambiguities in GLR grammers.
610 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
612 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
613 `bison ', use m4_index instead of m4_substr since chopping up a string
614 containing M4-special characters causes problems here.
616 Fix a couple of bugs related to special characters in user-specified
617 file names, and make it easier for skeletons to compute output file
618 names with the same file name prefix as Bison-computed output file
620 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
621 b4_parser_file_name and b4_spec_defines_file instead of
622 @output_parser_name@ and @output_header_name@, which are now redundant.
623 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
624 b4_parser_file_name, b4_spec_defines_file, and the new
625 @basename(FILENAME@) instead of @output_parser_name@ and
626 @output_header_name@, which inappropriately escaped the file names as
628 * src/files.c (all_but_ext): Remove static qualifier.
629 (compute_output_file_names): Move `free (all_but_ext)' to...
630 (output_file_names_free): ... here since all_but_ext is needed later.
631 * src/files.h (all_but_ext): Extern.
632 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
633 exactly what MUSCLE_INSERT_STRING used to do.
634 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
635 characters are escaped properly.
636 * src/output.c (prepare): Define muscle file_name_all_but_ext as
638 For pkgdatadir muscle, maintain previous functionality by using
639 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
640 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
641 digraphs would never be expanded. Hopefully no one has M4-special
642 characters in his Bison installation path.
643 * src/scan-skel.l: Don't parse @output_header_name@ and
644 @output_parser_name@ anymore since they're now redundant.
645 In @output, use decode_at_digraphs.
646 Parse a new @basename command that invokes last_component.
647 (decode_at_digraphs): New.
648 (BASE_QPUTS): Remove unused.
649 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
650 (Output file name): New tests.
652 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
654 Warn about output files that are generated by the skeletons and that
655 conflict with other output files.
656 * data/glr.c: Don't generate the header file here when glr.cc does.
657 * src/files.c (file_names, file_names_count): New static globals.
658 (compute_output_file_names): Invoke output_file_name_check for files
659 not generated by the skeletons and remove existing checks.
660 (output_file_name_check): New function that warns about conflicting
662 (output_file_names_free): Free file_names.
663 * src/files.h (output_file_name_check): Declare.
664 * src/scan-skel.l: Invoke output_file_name_check for files generated by
666 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
667 (Conflicting output files): New tests.
669 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
671 * doc/bison.texinfo: Fix a couple of typos.
673 2006-12-08 Bob Rossi <bob@brasko.net>
675 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
677 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
679 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
680 (yypush_parse): Rename yypvars argument to yyps and remove redundant
682 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
683 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
685 2006-12-07 Bob Rossi <bob@brasko.net>
686 and Joel Denny <jdenny@ces.clemson.edu>
688 * data/push.c (yypvarsinit): Change return type from void* to struct
689 yypvars*. No longer cast to void* on return.
690 (struct yypvars): Remove yylen since it need not be remembered between
691 yypushparse invocations.
692 (yypushparse): Don't copy between yylen and pv->yylen.
694 2006-12-05 Bob Rossi <bob@brasko.net>
696 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
697 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
698 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
699 (struct yypvars): Remove b4_declare_parser_variables.
700 (yypvarsinit): Remove init code for removed variables.
701 (global scope): Do not declare b4_declare_parser_variables if
703 (yypushparse): Add b4_declare_parser_variables.
704 Init new local variables, and remove init code for removed
707 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
708 and yyparse for other modes.
709 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
710 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
711 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
712 (AT_PURE_LEX_IF): True if pure or push parser.
714 2006-12-05 Joel E. Denny <jdenny@ces.clemson.edu>
716 Document Yacc prologue alternatives and default %destructor's and
717 %printer's as experimental. Don't mention Java yet. Discussed at
718 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00002.html>.
719 * NEWS (2.3a+): Say they're experimental. Remove any mention of Java.
720 (2.3a): Annotate this entry to say the old forms of these features were
722 * doc/bison.texinfo (Prologue Alternatives, Freeing Discarded Symbols,
723 Bison Symbols): Say they're experimental. Comment out any mention
724 of Java (we'll want this back eventually).
726 2006-12-01 Joel E. Denny <jdenny@ces.clemson.edu>
728 Support a file name argument to %defines. Deprecate `=' in

733 form of %defines, and remove `=' from entries for %file-prefix,
734 %name-prefix, and %output.
735 * src/parse-gram.y (prologue_declaration): Implement.
736 * tests/calc.at (Simple LALR Calculator, Simple GLR Calculator, Simple
737 LALR1 C++ Calculator, Simple GLR C++ Calculator): Remove the `=' from
738 all but one occurrence of %name-prefix.
739 * tests/headers.at (export YYLTYPE): Remove the `=' from %name-prefix.
740 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Likewise.
741 * tests/output.at (AT_CHECK_OUTPUT): Remove the `=' from all but one
742 occurrence of each of %file-prefix and %output. Add check for %defines
744 * tests/reduce.at (Useless Terminals, Useless Nonterminals,
745 Useless Rules, Reduced Automaton, Underivable Rules, Empty Language):
746 Remove the `=' from %output.
748 2006-11-21 Joel E. Denny <jdenny@ces.clemson.edu>
750 Don't escape $ in test case titles since Autoconf 2.61 now does that
752 * tests/actions.at (Default %printer and %destructor are not for error
753 or $undefined): Here.
754 (Default %printer and %destructor are not for $accept): Here.
755 * tests/input.at (Invalid $n and @n): Here.
757 2006-11-20 Joel E. Denny <jdenny@ces.clemson.edu>
759 Rename <!> to <>. Discussed starting at

766 * src/symlist.c (symbol_list_default_tagless_new): Update comment.
767 * src/symlist.h (symbol_list, symbol_list_default_tagless_new): Update
769 * tests/actions.at (Default tagless %printer and %destructor,
770 Default tagged and per-type %printer and %destructor,
771 Default %printer and %destructor are not for error or $undefined,
772 Default %printer and %destructor are not for $accept,
773 Default %printer and %destructor for mid-rule values): Update.
774 * tests/input.at (Default %printer and %destructor redeclared,
775 Unused values with default %destructor): Update.
777 2006-11-17 Joel E. Denny <jdenny@ces.clemson.edu>
779 Don't let %prec take a nonterminal.
780 * src/reader.c (grammar_current_rule_prec_set): Make the %prec symbol a
782 * tests/input.at (%prec takes a token): New test checking that %prec
783 won't take a nonterminal.
785 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
787 * tests/testsuite.at (AT_CHECK): Don't miss an exit value of 0 because
788 it was double-quoted.
789 * src/Makefile.am (YACC): Use --warnings=all,error so that Bison's own
790 grammar is maintained with Bison's highest standards.
791 * src/getargs.c: Fix some typos in Doxygen comments.
793 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
795 Fix memory leaks in scanners generated by at least Flex 2.5.9 and
796 later. Reported by Paul Eggert in
797 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
798 * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
799 * src/scan-code.l (translate_action): Don't bother invoking
800 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
801 (code_scanner_free): Instead of invoking
802 yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,
804 * src/scan-gram.l (gram_scanner_free): Likewise.
805 * src/scan-skel.l (scan_skel): Likewise.
807 2006-11-09 Joel E. Denny <jdenny@ces.clemson.edu>
809 * src/files.c (tr): Change return type to void.
810 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
811 has been called previously for the same key.
812 (muscle_find): Return storage instead of value so that
813 --enable-gcc-warnings doesn't produce warnings that the return discards
814 const. aver that the value and storage are the same since storage
815 could potentially be NULL when value is not.
816 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
819 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
821 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
822 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
823 us a slightly cleaner distribution, and also works.
824 * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
827 2006-11-08 Joel E. Denny <jdenny@ces.clemson.edu>
828 and Paul Eggert <eggert@cs.ucla.edu>
830 Don't let Bison leak memory except when it complains.
831 * src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):
832 (spec_defines_file, dir_prefix): Now char *, not const char *,
833 since they are freed.
834 * src/files.c: Likewise.
835 (all_but_ext, all_but_tab_ext, src_extension, header_extension):
837 (tr): Now operates in-place. All uses changed.
838 (compute_exts_from_gf, compute_exts_from_src): Don't leak temporary
840 (compute_file_name_parts, compute_output_file_names): Don't store
841 read-only data in variables that will be freed.
842 (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
843 src_extension, and header_extension.
844 (output_file_names_free): New public function to free
845 spec_verbose_file, spec_graph_file, spec_defines_file,
846 parser_file_name, and dir_prefix.
847 * src/getargs.c (getargs): Don't store read-only data in variables that
849 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
850 (which previously existed but was unused), and quotearg_free.
851 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
852 * src/muscle_tab.c: Likewise.
853 (muscle_entry): Make the value char const *,
854 and add a new storage member that is char * and can be freed.
855 (muscle_entry_free): New private function.
856 (muscle_init): Use it instead of free.
857 (muscle_insert, muscle_grow): Update and use new storage member.
858 (muscle_code_grow): Free the string passed to muscle_grow
859 since it's not needed anymore.
860 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
861 add a new `char *code' member.
862 ("{...}"): Declare semantic type as code.
863 * src/scan-code.h (translate_rule_action):
864 (translate_symbol_action, translate_code, translate_action): Return
865 `char const *' rather than `char *' since external code should not free
867 * src/scan-code.l: Likewise.
868 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
869 which is "{...}" in the parser.
870 * tests/Makefile.am (maintainer-check-valgrind): Set
871 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
873 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
875 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
876 expecting a non-zero exit status sets --leak-check=summary and
877 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
878 this case, and we don't want to hear about it.
880 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
882 * bootstrap (runtime-po/Makevars): Derive from po/Makevars
883 instead of from the template, to simplify configuration a bit.
884 * bootstrap.conf (excluded_files): Don't exclude m4/codeset.m4

985 * src/reader.c (packgram): Remove the `$' from each midrule symbol
986 name for which the midrule value is referenced in any action.

997 (packgram): Before invoking grammar_rule_check on any rule, make sure
998 all actions have already been scanned in order to set `used' flags.
999 Otherwise, checking that a midrule's $$ is set will not always work
1000 properly because the midrule check must forward-reference the midrule's

1014 2006-10-16 Joel E. Denny <jdenny@ces.clemson.edu>
1016 Similar to the recently removed %before-header, add %code-top as the

1135 * bootstrap (usage, main program, symlink_to_gnulib): Add option
1136 --copy. Inspired by a suggestion from Bruno Haible.
1138 2006-10-03 Jim Meyering <jim@meyering.net>

1141 sticks with the automake default in generating dependencies.
1143 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
1145 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than

1250 Automatically generated dependencies are important even
1251 when all of the sources in a directory come from gnulib.
1252 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake

1293 Avoid making a copy if it's the same as the old version.
1294 (gnulib_files): Add support for this variable (used by Bison).
1296 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
1298 * src/getargs.c (usage): Rework to use conventions similar to
1299 coreutils, to make translation a bit easier and the code a bit
1300 smaller. Problem reported by Tim Van Holder.
1302 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
1304 Use some of gnulib's new modules, taken from coreutils.

1314 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
1316 (GNULIB_AUTOCONF_SNIPPET): Remove.
1317 (AM_GNU_GETTEXT): Add; require formatstring macros since that's

1330 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
1331 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
1332 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
1333 * src/system.h: Include inttypes.h unconditionally, now that we
1334 use the inttypes module. Don't bother to include stdint.h, since
1335 inttypes.h now does that for us.

1345 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
1347 * src/parse-gram.y (symbol_declaration): Don't put statements
1348 before declarations; it's not portable to C89.
1349 * src/scan-code.l (handle_action_at): Likewise.
1351 * src/scan-code.l: Always initialize braces_level; the old code
1352 left it uninitialized and therefore had undefined behavior.
1354 Don't attempt to redefine 'assert', since it runs afoul of
1355 systems where standard headers (mistakenly) include <assert.h>.
1356 Instead, define and use our own alternative, called 'aver'.
1357 * src/reader.c: Don't include assert.h, since we no longer
1359 * src/scan-code.l: Likewise.
1360 * src/system.h (assert): Remove, replacing with....
1361 (aver): New function, taking a bool arg. All uses changed.
1362 * src/tables.c (pack_vector): Ensure that aver arg is bool,
1363 not merely an integer.
1365 2006-09-15 Bob Rossi <bob@brasko.net>
1367 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
1368 * data/c.m4 (YYPUSH): New.
1369 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
1370 * src/getargs.c (push_parser): New var.
1371 * src/getargs.h (push_parser): New declaration.
1372 * src/output.c (prepare): Add macro insertion of `push_flag'.
1373 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
1374 (prologue_declaration): Parse %push-parser.
1375 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
1376 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
1377 list of removed lines from the traces observed.
1378 (AT_CHECK_CALC_LALR): Added push parser tests.
1380 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
1382 * NEWS: Version 2.3a.
1383 * configure.ac (AC_INIT): Likewise.
1385 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
1386 "#define YYSTYPE int" that caused "make maintainer-check" to fail
1387 due to header ordering dependencies. I don't know why the #define
1390 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
1391 runtime cost when YYDEBUG is not defined, and so that some tests
1392 that used to fail now work. Problem and initial suggestion by
1394 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
1395 * data/glr.cc (b4_parser_class_name):
1396 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
1397 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
1398 (yydebug_) [YYDEBUG]: New member.
1399 (yycdebug_): Now defined only if YYDEBUG.
1400 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
1401 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
1402 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
1404 (debug_stream, set_debug_stream, debug_level, set_debug_level):
1405 Define only if YYDEBUG.
1406 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
1408 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
1409 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
1410 AT_CHECK_CALC_GLR_CC that are working now.
1412 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
1414 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
1415 We don't need them in glr.cc, and glr.c defines them.
1416 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
1417 assumes that defining it to anything is the same as defining
1418 it to 1. Problem reported by Paolo Bonzini.
1420 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
1422 * data/c.m4 (b4_null, b4_case): Define.
1423 * src/output.c (prepare_symbols): Use b4_null.
1424 (user_actions_output): Use b4_case.
1426 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
1428 * data/glr.c (b4_shared_declarations): Put start-header first,
1429 before any #includes that we generate, so that feature-test
1430 macros work. Problem reported by Michael Deutschmann in
1431 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
1432 * data/lalr1.cc: Likewise.
1433 * doc/bison.texinfo (Prologue): Document that feature-test macros
1434 should be defined before any Bison declarations.
1435 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
1436 that depend on location.hh after, not before, Bison decls, since
1437 we now include location.hh after the first user prologue.
1439 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
1440 Sander Brandenburg in
1441 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
1442 Also, fix minor white space and comment issues.
1443 (Prologue): Mention that it's better to define feature-test macros
1444 before Bison declarations. Problem reported by Michael Deutschmann.
1446 * README-cvs: Fix typo: "&" should be "&&". Problem reported
1448 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
1449 This adjusts to recent gnulib changes.
1451 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
1453 Finish implementation of per-type %destructor/%printer. Discussed
1455 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
1457 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
1458 * NEWS (2.3+): Add a description of this feature to the default
1459 %destructor/%printer description.
1460 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
1461 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
1462 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
1463 list node contains a semantic type.
1464 * src/symtab.c, src/symtab.h: Extend with a table that associates
1465 semantic types with their %destructor's and %printer's.
1466 (semantic_type_from_uniqstr, semantic_type_get,
1467 semantic_type_destructor_set, semantic_type_printer_set): New functions
1468 composing the public interface of that table.
1469 (symbol_destructor_get, symbol_destructor_location_get,
1470 symbol_printer_get, symbol_printer_location_get): If there's no
1471 per-symbol %destructor/%printer, look up the per-type before trying
1473 * tests/actions.at (Per-type %printer and %destructor): New test case.
1474 * tests/input.at (Default %printer and %destructor redeclared):
1475 Extend to check that multiple occurrences of %symbol-default in a
1476 single %destructor/%printer declaration is an error.
1477 (Per-type %printer and %destructor redeclared, Unused values with
1478 per-type %destructor): New test cases.
1480 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
1482 Require default %destructor/%printer to be declared using
1483 %symbol-default instead of an empty symbol list, and start working on
1484 new per-type %destructor/%printer. Discussed at
1485 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
1486 * NEWS (2.3+): Add %symbol-default to example.
1487 * bison.texinfo (Freeing Discarded Symbols): Likewise.
1488 (Bison Symbols): Add entry for %symbol-default.
1489 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
1490 (generic_symlist, generic_symlist_item): New nonterminals for creating
1491 a list in which each item is a symbol, semantic type, or
1493 (grammar_declaration): Use generic_symlist in %destructor and %printer
1494 declarations instead of symbols.1 or an empty list.
1495 (symbol_declaration, precedence_declaration, symbols.1): Update actions
1496 for changes to symbol_list.
1497 * src/reader.c: Update for changes to symbol_list.
1498 * src/scan-code.l: Likewise.
1499 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
1500 * src/symlist.c, src/symlist.h: Extend such that a list node may
1501 represent a semantic type or a %symbol-default in addition to just an
1502 ordinary symbol. Add switched functions for setting %destructor's and
1504 * tests/actions.at, tests/input.at: Add %symbol-default to all default
1505 %destructor/%printer declarations.
1507 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
1509 Whether the default %destructor/%printer applies to a particular symbol
1510 isn't a question of whether the user *declares* that symbol (in %token,
1511 for example). It's a question of whether the user by any means
1512 *defines* the symbol at all (by simply using a char token, for
1513 example). $end is defined by Bison whereas any other token with token
1514 number 0 is defined by the user. The error token is always defined by
1515 Bison regardless of whether the user declares it with %token, but we
1516 may one day let the user define error as a nonterminal instead.
1517 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
1518 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
1519 the meaning of "user-defined".
1520 * tests/actions.at (Default %printer and %destructor for user-declared
1521 end token): Rename to...
1522 (Default %printer and %destructor for user-defined end token): ...
1525 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
1526 computation of whether to apply the default, don't maintain a list of
1527 every Bison-defined symbol. Instead, just check for a first character
1528 of '$', which a user symbol cannot have, and check for the error token.
1530 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
1532 Don't apply the default %destructor or %printer to the error token,
1533 $undefined, or $accept. This change fits the general rule that the
1534 default %destructor and %printer are only for user-declared symbols,
1535 and it solves several difficulties that are described in the new test
1537 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
1538 * tests/actions.at (Default %printer and %destructor are not for error
1539 or $undefined, Default %printer and %destructor are not for $accept):
1542 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
1544 Allow %start after the first rule.
1545 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
1546 when parsing the first rule.
1547 (check_and_convert_grammar): Search for it here after all grammar
1548 declarations have been parsed. Skip midrules, which have dummy LHS
1550 * src/symtab.c (symbol_is_dummy): New function.
1551 * src/symtab.h (symbol_is_dummy): Declare it.
1552 * tests/input.at (%start after first rule): New test.
1554 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
1556 Redo some of the previous commit: add back the ability to use
1557 non-aliased/undeclared string literals since it might be useful to
1558 those declaring %token-table.
1559 * src/reader.c (check_and_convert_grammar): Undo changes in previous
1560 commit: don't worry about complaints from symbols_pack.
1561 * src/symtab.c (symbol_new, symbol_class_set,
1562 symbol_check_alias_consistency): Undo changes in previous commit: count
1563 each string literal as a new symbol and token, assign it a symbol
1564 number, and don't complain about non-aliased string literals.
1565 (symbols_pack): Since symbol_make_alias still does not decrement symbol
1566 and token counts but does still set aliased tokens to the same number,
1567 symbol_pack_processor now leaves empty slots in the symbols array.
1569 * tests/regression.at (Undeclared string literal): Remove test case
1570 added in previous commit since non-aliased string literals are allowed
1572 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
1573 remove unnecessary string literal declarations.
1574 * tests/sets.at (Firsts): Likewise.
1576 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
1578 Don't allow an undeclared string literal, but allow a string literal to
1579 be used before its declaration.
1580 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
1581 symbols_pack complained.
1582 * src/symtab.c (symbol_new): Don't count a string literal as a new
1584 (symbol_class_set): Don't count a string literal as a new token, and
1585 don't assign it a symbol number since symbol_make_alias does that.
1586 (symbol_make_alias): It's not necessary to decrement the symbol and
1587 token counts anymore. Don't assume that an alias declaration occurs
1588 before any uses of the identifier or string, and thus don't assert that
1589 one of them has the highest symbol number so far.
1590 (symbol_check_alias_consistency): Complain if there's a string literal
1591 that wasn't declared as an alias.
1592 (symbols_pack): Bail if symbol_check_alias_consistency failed since
1593 symbol_pack asserts that every token has been assigned a symbol number
1594 although undeclared string literals have not.
1595 * tests/regression.at (String alias declared after use, Undeclared
1596 string literal): New test cases.
1597 (Characters Escapes, Web2c Actions): Declare string literals as
1599 * tests/sets.at (Firsts): Likewise.
1601 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
1603 In the grammar scanner, STRING_FINISH unclosed constructs and return
1604 them to the parser in order to improve error messages.
1605 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
1606 SC_BRACED_CODE, SC_PROLOGUE): Implement.
1607 * tests/input.at (Unclosed constructs): New test case.
1608 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
1611 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
1614 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
1616 Handle string aliases for character tokens correctly.
1617 * src/symtab.c (symbol_user_token_number_set): If the token has an
1618 alias, check and set its alias's user token number instead of its own,
1619 which is set to indicate the alias. Previously, every occurrence of
1620 the character token in the grammar overwrote that alias indicator with
1622 * tests/input.at (String aliases for character tokens): New test.
1624 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
1626 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
1628 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
1630 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
1631 to prevent failures when building on older platforms.
1632 Check for autopoint failure.
1633 Set XGETTEXT_OPTIONS to values that check for C format strings,
1634 so that translators are warned about them (this also helps
1635 prevent core dumps).
1637 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
1638 function, since it simplifies our code a bit.
1640 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
1641 rather than -W, so we don't get bogus warnings about sign comparisons.
1642 Add -Wpointer-arith, since that warning is useful (it reports code
1643 that does not conform to C89 and that some compilers reject).
1644 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
1645 since it's no longer needed.
1647 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
1649 Clean up scanners a bit.
1650 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
1651 definitions so gcc won't warn when obstack_for_string is unused.
1652 * src/scan-code.l: config.h and system.h are already #include'd by
1653 scan-code-c.c, so get rid of them here.
1654 * src/scan-gram.l: Likewise.
1655 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
1656 definitions rather than duplicating the rest of it.
1657 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
1659 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
1661 Suppress signed/unsigned comparison warnings for yycheck.
1662 * data/c.m4 (b4_safest_int_type): New macro.
1663 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
1664 a signed int type, cast it to b4_safest_int_type first.
1665 * data/yacc.c: Likewise.
1666 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
1669 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
1671 * doc/bison.texinfo: Fix some typos.
1673 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
1675 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
1676 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
1678 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
1679 the latest gnulib does this a different way.
1680 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
1681 translation was patched, so stop omitting it.
1683 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
1685 Enable declaration of default %printer/%destructor. Make the parser
1686 use these for all user-declared grammar symbols for which the user does
1687 not declare a specific %printer/%destructor. Thus, the parser uses it
1688 for token 0 if the user declares it but not if Bison generates it as
1689 $end. Discussed starting at
1690 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
1691 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
1693 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
1694 * NEWS (2.3+): Mention.
1695 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
1696 declare a %destructor for a mid-rule's semantic value. It's just
1697 impossible to declare one specific to it.
1698 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
1699 code. Describe default %destructor form.
1700 * src/parse-gram.y (grammar_declaration): Parse default
1701 %printer/%destructor declarations.
1702 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
1703 and symbol_destructor_location_get rather than accessing the destructor
1704 and destructor_location members of struct symbol.
1705 (symbol_printers_output): Likewise but for %printer's.
1706 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
1708 * src/symtab.c (default_destructor, default_destructor_location,
1709 default_printer, default_printer_location): New static global
1710 variables to record the default %destructor and %printer.
1711 (symbol_destructor_get, symbol_destructor_location_get,
1712 symbol_printer_get, symbol_printer_location_get): New functions to
1713 compute the appropriate %destructor and %printer for a symbol.
1714 (default_destructor_set, default_printer_set): New functions to set the
1715 default %destructor and %printer.
1716 * src/symtab.h: Prototype all those new functions.
1717 * tests/actions.at (Default %printer and %destructor): New test to
1718 check that the right %printer and %destructor are called, that they're
1719 not called for $end, and that $$ and @$ work correctly.
1720 (Default %printer and %destructor for user-declared end token): New
1721 test to check that the default %printer and %destructor are called for
1722 a user-declared end token.
1723 * tests/input.at (Default %printer and %destructor redeclared, Unused
1724 values with default %destructor): New tests to check related grammar
1725 warnings and errors.
1727 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
1729 Clean up handling of %destructor for the end token (token 0).
1730 Discussed starting at
1731 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
1733 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
1735 Make the skeletons consistent in how they pop the end token and invoke
1737 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
1738 state, which has token number 0, since this would invoke the
1739 %destructor for the end token.
1740 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
1741 until after shifting the end token, or else it won't be popped.
1742 * data/yacc.c (yyparse): Likewise.
1744 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
1745 it's the end token. Upon termination, destroy an unshifted lookahead
1746 even when it's the end token.
1747 * data/lalr1.cc (yy::parser::parse): Likewise.
1748 * data/yacc.c (yyparse): Likewise.
1750 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
1751 value warnings for the end token when the user gives the end token a
1754 * tests/actions.at (Printers and Destructors): Test all the above.
1756 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
1758 Update to latest gnulib and gettext versions.
1759 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
1761 (gnulib_files): Add m4/warning.m4. Don't worry about files
1762 overwritten by autopoint.
1763 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
1764 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
1766 Don't use autoreconf; instead, invoke autopoint etc. by hand,
1767 so that we can remove the intl files at a better time.
1768 (intl_files_to_remove): Remove aclocal.m4, since it gets
1769 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
1770 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
1771 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
1772 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
1773 Remove datarootdir hack; no longer needed.
1774 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
1775 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
1776 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
1778 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
1779 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
1781 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
1783 * bootstrap: Adjust to today's change to gnulib-tool by invoking
1784 it with --assume-autoconf='latest-stable'.
1786 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
1788 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
1789 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
1791 * src/muscle_tab.h (muscle_grow): Replace the header comments with
1792 those from muscle_tab.c since the old ones are misleading.
1794 2006-07-13 Akim Demaille <akim@epita.fr>
1796 Support %define "KEY" {VALUE}.
1797 * src/scan-code.h, src/scan-code.l (translate_action)
1798 (translate_rule_action, translate_symbol_action, translate_code):
1799 Return char *, not const char *.
1800 * src/parse-gram.y (declaration): Rename as...
1801 (prologue_declaration): this.
1802 (string_content): Remove this nonterminal, use STRING.
1803 (braceless, content, content.opt): New nonterminal.
1805 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
1807 * src/scan-gram.l (getargs.h): Don't include it.
1809 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
1811 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
1812 rather than a for-loop that declares a local bool variable. This
1813 should work around a compatibility problem with a Cray x1e C++
1814 compiler reported by Hung Nguyen in
1815 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
1816 The for-loop was introduced in the 2004-11-17 change but I don't
1817 know why it was needed.
1819 2006-07-12 Akim Demaille <akim@epita.fr>
1821 * data/c.m4: Comment changes.
1823 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
1825 * src/complain.c (error_message, ERROR_MESSAGE): New.
1827 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
1828 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
1830 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
1832 * NEWS: Instead of %union, you can define and use your own union type
1833 YYSTYPE if your grammar contains at least one <type> tag.
1834 Your YYSTYPE need not be a macro; it can be a typedef.
1835 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
1836 (Union Decl, Decl Summary): Document this.
1837 * data/glr.c (YYSTYPE): Implement this.
1838 * data/glr.cc (YYSTYPE): Likewise.
1839 * data/lalr1.cc (YYSTYPE): Likewise.
1840 * data/yacc.c (YYSTYPE): Likewise.
1841 * src/output.c (prepare): Output tag_seen_flag.
1842 * src/parse-gram.y (declaration, grammar_declaration):
1843 Use 'union_seen' rather than 'typed' to determine whether
1844 %union has been seen, since grammars can now be typed without
1846 (symbol_declaration, type.opt, symbol_def):
1847 Keep track of whether a tag has been seen.
1848 * src/reader.c (union_seen, tag_seen): New vars.
1850 * src/reader.h (union_seen, tag_seen, typed): Likewise.
1851 * src/scan-code.l (untyped_var_seen): New variable.
1852 (handle_action_dollar): Adjust to above changes.
1853 (handle_action_dollar, handle_action_at):
1854 Improve overflow checking for outlandish numbers.
1855 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
1856 avoid new diagnostics generated by above changes.
1857 * tests/regression.at (YYSTYPE typedef): Add test to check
1858 for type tags without %union.
1860 * src/symlist.c (symbol_list_length): Return int, not unsigned
1861 int, since callers expect int. This may need to get revisited
1862 once we have proper integer overflow checking.
1864 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
1865 object is now static.
1867 * src/getargs.c (flags_argmatch): Return void, not int,
1868 to pacify ./configure --enable-gcc-warnings.
1870 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
1871 since last_string is already defined to FLEX_PREFIX (last_string).
1873 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
1875 Implement --warnings/-W.
1876 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
1878 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
1880 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
1881 (warnings_args, warnings_types): New.
1882 (getargs, short_options, long_options): Accept -W/--warnings.
1883 Sort the options by alphabetical order, upper case letter right
1884 before its lower case.
1886 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
1888 Change %merge result type clash warnings to errors. Discussed at
1889 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
1890 * src/reader.c (record_merge_function_type): Use complain_at.
1891 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
1892 declared later): Update test case results.
1894 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
1896 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
1897 to be in alphabetical order.
1898 (trace_args): Spelling fixes.
1900 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
1902 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
1903 so they don't collide with user-defined macros.
1904 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
1905 this was never guaranteed, and now that we're using gnulib stdint,
1906 which defines int_fast16_t to long int, the problem is exposed.
1908 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
1910 * data/c.m4 (b4_basename): Simplify a bit, since we don't
1911 need the full POSIX semantics (and weren't implementing them
1914 Adjust to Autoconf 2.60 and today's gnulib.
1915 * bootstrap (gnulib_modules): Add stdint.
1916 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
1917 no longer copies it.
1918 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
1919 since stdint needs the former and wcwidth (which is now required
1920 by mbswidth) needs the latter.
1921 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
1922 work around a compatibility glitch between gettext 0.14.6 and
1924 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
1925 Do not check for uintptr_t, since new stdint module does the right
1927 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
1928 Add stdint.h, stdint_.h, wcwidth.h.
1929 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
1930 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
1931 stdint.m4, wchar_t.m4, wcwidth.m4.
1932 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
1933 usual order for ../lib/*.h files.
1934 (file_name_split): Use last_component, not base_name, to adjust
1936 * src/parse-gram.h: Include <strverscmp.h> in the usual order
1937 for ../lib/*.h files.
1938 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
1939 Define unconditionally, since we now assume the stdint module.
1940 * src/scan-skel.l: Include <dirname.h>.
1941 (BASE_QPUTS): Use last_component, not base_name.
1942 * src/system.h: Include <unlocked-io.h> in the usual order
1943 for ../lib/*.h files. Include <stdint.h> unconditionally,
1944 since we now use the stdint module.
1945 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
1946 HAVE_UINTPTR_T, since we now use the stdint module.
1947 (base_name): Remove decl, since files now include <dirname.h>
1950 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
1952 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
1954 * data/yacc.c, data/glr.c, data/location.cc: Use them.
1955 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
1957 * tests/calc.at: Adjust.
1959 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
1961 * data/c.m4 (b4_basename): New.
1962 (b4_syncline): Also output the location of its invocation (from
1964 (b4_user_action, b4_define_user_action, b4_user_actions)
1965 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
1966 (b4_user_stype): New.
1967 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
1969 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
1971 In the grammar file, the first column is 1 not 0 on the first line as
1972 on every other line.
1973 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
1974 * tests/input.at (Torturing the Scanner): Update output.
1976 * src/scan-gram.l (scanner_cursor): Declare it static.
1978 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
1980 In warnings, say "previous declaration" rather than "first
1982 * src/symtab.c (redeclaration): Do that here.
1983 * src/reader.c (record_merge_function_type): In the case of a result
1984 type clash, report the previous declaration rather than the very first
1985 one in the grammar file.
1986 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
1987 declared later): Add a third declaration to check this behavior.
1988 * tests/input.at (Incompatible Aliases): Update output.
1990 2006-06-27 Akim Demaille <akim@epita.fr>
1992 * doc/Doxyfile.in: New.
1993 * doc/Makefile.am: Use it.
1994 * src/lalr.h, src/symtab.h: Initial doxygenation.
1996 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
1998 Don't miss %merge result type warnings just because the LHS types are
1999 declared after the %merge. This continues the effort of the previous
2001 * src/reader.c (get_merge_function): Don't set the merger type yet.
2002 (record_merge_function_type): New function for setting the merger type
2003 and checking for clashes.
2004 (grammar_current_rule_merge_set): Set the location of the %merge for
2006 (packgram): Invoke record_merge_function_type for each rule now that
2007 all symbol type declarations have been parsed.
2008 * src/reader.h (merger_list.type_declaration_location): New member
2009 storing the location of the first %merge from which the type for this
2010 merging function was derived.
2011 * src/symlist.h (symbol_list.merger_declaration_location): New member
2012 storing the location of a rule's %merge, if any.
2013 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
2014 declared later): New test to catch the error fixed by the above patch.
2016 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
2018 Get action warnings (grammar_rule_check) right even when symbol
2019 declarations appear after the rules. Discussed at
2020 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
2022 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
2023 Don't mistake the type of $$ in a midrule to be that of its parent
2025 * src/reader.c (grammar_current_rule_end): Don't invoke
2026 grammar_rule_check yet since not all symbol declarations may have been
2028 (grammar_midrule_action): Likewise.
2029 Don't record whether the midrule's $$ has been used yet since actions
2030 haven't been translated yet.
2031 Record the midrule's parent rule and its RHS index within the parent
2033 (grammar_current_rule_action_append): Don't translate the action yet
2034 since not all symbol declarations may have been parsed yet and, thus,
2035 warnings about types for $$, $n, @$, and @n can't be reported yet.
2036 (packgram): Translate the action and invoke grammar_rule_check now that
2037 all symbol declarations have been parsed.
2038 * src/scan-code.l (handle_action_dollar): Now that this is invoked
2039 after parsing the entire grammar file, the symbol list here in the case
2040 of a midrule is actually the midrule's empty RHS, so reference its
2041 parent rule's RHS where necessary.
2042 On the other hand, now that you can already know it's a midrule, you
2043 aren't forced to think $$ has the same type as its parent rule's $$.
2044 (handle_action_at): In the case of a midrule, reference the parent rule
2046 * src/symlist.c (symbol_list_new): Initialize new midrule-related
2048 (symbol_list_length): Now that this is invoked after all rules have
2049 been parsed, a NULL symbol (rather than a NULL symbol list node)
2050 terminates a rule. symbol_list_print already does this correctly.
2051 * src/symlist.h (symbol_list.midrule_parent_rule,
2052 symbol_list.midrule_parent_rhs_index): New members so that midrules can
2053 remember their relationships with their parents.
2054 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
2055 fixed by the above patch.
2056 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
2058 (Unused values): ... this old test case and...
2059 (Unused values before symbol declarations): ... this new test case.
2060 This one is the same as `Unused values' except that all symbol
2061 declarations appear after the rules in order to catch the rest of the
2062 errors fixed by the above patch.
2064 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
2067 * src/reader.c (current_rule): Declare it static since it's no longer
2068 used outside this file.
2069 (grammar_current_rule_action_append): Remove redundant arguments from
2070 translate_rule_action invocation.
2071 * src/reader.h (current_rule): Remove this unused extern.
2072 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
2073 * src/scan-code.l (translate_rule_action): Likewise.
2075 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
2077 Clean up yesterday's patch.
2078 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
2080 * src/reader.c (grammar_current_rule_action_append): ... here for
2081 consistency with grammar_current_rule_symbol_append.
2082 * tests/regression.at (Braced code in declaration in rules section):
2083 Make yyerror and yylex static as usual.
2085 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
2087 Fix bug that mistakes braced code in a declaration in the rules section
2088 to be a rule action. Mentioned at
2089 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
2090 * src/scan-gram.l: Move midrule action detection from the start of the
2091 scanning of any braced code to...
2092 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
2093 action. For readability, use $2 and @2 rather than the equivalent
2095 * tests/regression.at (Braced code in declaration in rules section):
2096 New test to catch the error fixed by the above patch.
2098 Work on code readability some.
2099 * src/scan-code.l (current_rule): Get rid of this misleading and
2100 redundant declaration: it's actually extern'ed in reader.h.
2101 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
2102 translate_action): Add a rule argument and use it instead of the global
2104 (translate_rule_action): This already receives current_rule through an
2105 argument, so pass it on to translate_action instead of assigning
2106 current_rule to current_rule.
2107 (translate_symbol_action, translate_code): Pass rule = NULL to
2110 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
2112 Rename %before-definitions to %start-header and %after-definitions to
2113 %end-header. Don't use these declarations to separate pre-prologue
2114 blocks from post-prologue blocks. Add new order-independent
2115 declarations %before-header and %after-header as alternatives to the
2116 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
2117 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
2118 * NEWS (2.3+): Update for these changes.
2119 * data/glr.c (b4_before_definitions): Update to...
2120 (b4_start_header): ... this.
2121 (b4_after_definitions): Update to...
2122 (b4_end_header): ... this.
2123 * data/glr.cc: Likewise.
2124 * data/lalr1.cc: Likewise.
2125 * data/yacc.c: Likewise.
2126 * doc/bison.texinfo (The prologue): Update names, and replace remaining
2127 prologue blocks with %*-header declarations.
2128 (Calc++ Parser): Likewise.
2129 (Bison Declaration Summary): Update names.
2130 (Bison Symbols): Update description.
2131 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
2132 (PERCENT_END_HEADER): ... this.
2133 (PERCENT_BEFORE_DEFINITIONS): Update to...
2134 (PERCENT_START_HEADER): ... this.
2135 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
2136 (declaration): Update token names and m4 macro names.
2137 When parsing %end-header and %start-header, invoke translate_code
2138 before muscle_code_grow, and no longer set global booleans to remember
2139 whether these declarations have been seen.
2140 Parse new %after-header and %before-header.
2141 * src/reader.c (before_definitions, after_definitions): Remove.
2142 (prologue_augment): Accept a new bool argument to specify whether to
2143 augment the pre-prologue or post-prologue.
2144 * src/reader.h (before_definitions, after_definitions): Remove these
2146 (prologue_augment): Add new bool argument.
2147 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
2148 (PERCENT_END_HEADER): ... this.
2149 (PERCENT_BEFORE_DEFINITIONS): Update to...
2150 (PERCENT_START_HEADER): ... this.
2151 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
2152 * tests/actions.at (Printers and Destructors): Update names.
2154 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
2156 Add comparison operators for C++ location classes. Discussed at
2157 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
2158 * data/c++.m4 (b4_define_location_comparison): New boolean %define
2159 declaration indicating whether filename_type has an operator==. If
2160 filename_type is `std::string', it defaults to `1', `0' otherwise.
2161 * data/location.cc: Iff b4_define_location_comparison is `1', add
2162 operator== and operator!= for class position and for class location.
2165 * src/scan-action.l: Remove unused file.
2166 * src/symtab.c (symbol_printer_set): Use printer_location not
2167 destructor_location.
2168 * src/symtab.h (struct symbol): Replace incorrect source comment for
2170 * tests/input.at (Incompatible Aliases): Update output with correct
2173 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
2175 Don't put the pre-prologue in the header file. For the yacc.c code
2176 file and the glr.c header and code files, move the pre-prologue before
2177 the token definitions. Add new %before-definitions and
2178 %after-definitions to declare code that will go in both the header file
2179 and code file. Discussed at
2180 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
2181 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
2183 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
2184 * NEWS (2.3+): Describe these changes.
2185 * data/glr.c (b4_pre_prologue): Move from within to before...
2186 (b4_shared_declarations): ... this.
2187 Add new b4_before_definitions before b4_token_enums.
2188 Add new b4_after_definitions at the end.
2189 * data/glr.cc (b4_pre_prologue): Replace with...
2190 (b4_before_definitions): ... this in the header file.
2191 (b4_after_definitions): New near the end of the header file.
2192 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
2193 code file right before including the header file.
2194 (b4_before_definitions): New in the previous position of
2195 b4_pre_prologue in the header file.
2196 (b4_after_definitions): New near the end of the header file.
2197 * data/yacc.c: Clean up some m4 quoting especially in the header file.
2198 (b4_token_enums_defines): In the code file, move to right before
2199 YYSTYPE for consistency with the header file.
2200 (b4_before_definitions): New right before b4_token_enums_defines in
2201 both the header and code file.
2202 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
2203 header and code file.
2204 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
2205 of prologues for %union dependencies.
2206 (Bison Declaration Summary): In %defines description, mention the
2207 effect of %before-definitions and %after-definitions on the header
2209 (Calc++ Parser): Forward declare driver in a %before-definitions rather
2210 than in the pre-prologue so that make check succeeds.
2211 (Bison Symbols): Add entries for %before-definitions and
2213 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
2214 %before-definitions.
2215 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
2216 (declaration): Parse those declarations and append to
2217 b4_before_definitions and b4_after_definitions, respectively.
2218 * src/reader.c (before_definitions, after_definitions): New bools to
2219 track whether those declarations have been seen.
2220 (prologue_augment): Add to the post-prologue if %union,
2221 %before-definitions, or %after-definitions has been seen.
2222 * src/reader.h (before_definitions, after_definitions): New extern's.
2223 * src/scan-gram.l: Scan the new declarations.
2224 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
2225 prologue block in a %before-definitions or a %after-definitions based
2226 on whether the %union is declared.
2227 * tests/regression.at (Early token definitions with --yacc, Early token
2228 definitions without --yacc): Move tests for token definitions into the
2229 post-prologue since token names are no longer defined in the
2232 2006-06-20 Akim Demaille <akim@epita.fr>
2234 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
2235 (symbol_get): Use it.
2236 * src/parse-gram.y: Use it.
2238 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
2240 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
2241 build succeeds when configured with --enable-gcc-warnings.
2243 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
2245 * src/parse-gram.y (char_name): New function.
2246 (CHAR, STRING, string_content): For %printer, properly escape.
2247 (ID): Prefer fputs to fprintf.
2248 (id): Reindent to be consistent with other rules.
2249 Properly quote char.
2251 The Translation Project changed its way of publishing translations
2252 to maintainers. I haven't received any responses to my request
2253 for supporting the old way, or for documenting the new way. I
2254 have modified 'bootstrap' to use screen scraping
2255 (in this case, HTML scraping). This is unreliable and inelegant,
2256 but I don't see any better way. Yuck.
2257 * bootstrap (TP_URL, WGET_COMMAND): New vars.
2258 (get_translations): New function, which uses HTML scraping to
2259 deduce locations of latest translations.
2260 Use this function to grab both bison and bison-runtime .po files.
2261 Don't bother priming the pump for the runtime-po domain any more,
2262 as it's now translated better than bison is.
2264 2006-06-19 Akim Demaille <akim@epita.fr>
2266 * src/scan-gram.l: No longer "parse" things after `%union' until
2267 `{'. Rather, return a single "%union" token.
2268 No longer make symbols: return strings, and leave the conversion
2269 to symbols to the parser.
2270 (SC_PRE_CODE, token_type): Remove.
2271 * src/parse-gram.y (%union): New field `character'.
2274 (ID, ID_COLON): Now that the scanner no longer makes them
2275 identifiers, adjust all uses to invoke symbol_get.
2276 (id_colon): New, wraps the conversion from string to symbol.
2277 (%union): Accept a possible union_name.
2278 (symbol): Now can be a char.
2279 * data/c.m4 (b4_union_name): Leave a default value.
2280 * data/glr.c, data/yacc.c: Use it.
2282 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
2284 For associating token numbers with token names for "yacc.c", don't use
2285 #define statements unless `--yacc' is specified; always use enum
2286 yytokentype. Most important discussions start at:
2287 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
2288 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
2290 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
2291 * NEWS (2.3+): Mention.
2292 * data/c.m4 (b4_yacc_if): New.
2293 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
2295 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
2296 on token name definitions.
2297 * src/getargs.c (usage): Capitalize `Yacc' in English.
2298 * src/output.c (prepare): Define b4_yacc_flag.
2299 * tests/regression.at (Early token definitions): Test that tokens names
2300 are defined before the pre-prologue not just before the post-prologue.
2301 Remove this test case and copy to...
2302 (Early token definitions with --yacc): ... this to test #define's.
2303 (Early token definitions without --yacc): ... and this to test enums.
2305 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
2307 * NEWS: Reword the post-2.3 change to not be so optimistic about
2308 removing the old "look-ahead" spelling.
2309 Update previous look-ahead/lookahead change reports.
2310 * REFERENCES: look-ahead -> lookahead (since that's
2311 what he actually wrote).
2312 * doc/refcard.tex: look ahead -> lookahead,
2313 look-ahead -> lookahead
2315 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
2317 For consistency, use `lookahead' instead of `look-ahead' or
2318 `look_ahead'. Discussed starting at

2392 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
2394 * TODO: Add request from Nelson H. F. Beebe to be able to install
2395 Bison without installing the yacc script.
2397 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
2399 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
2400 and yytext if they're already #define'd.
2401 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
2402 * src/scan-code-c.c: ... here.
2403 * src/scan-code.l, src/scan-gram.l: ... and here. Also #include

2408 Get Bison to build again when configured with --enable-gcc-warnings.
2409 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
2411 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
2412 loc argument as it shadows a global.
2413 * src/scan-gram.l: Remove stray comma that prevents boundary_set
2416 * src/.cvsignore: Add scan-code.c.
2418 2006-06-07 Akim Demaille <akim@epita.fr>
2420 * src/scan-gram.l: Move the "add a trailing ; to actions" code
2422 * src/scan-code.l: here.
2423 * tests/input.at (Torturing the Scanner): Fix another location
2426 2006-06-07 Akim Demaille <akim@epita.fr>
2428 * src/Makefile.am (BUILT_SOURCES): Fix the trailing backslash.
2430 2006-06-06 Akim Demaille <akim@epita.fr>
2432 Extract the parsing of user actions from the grammar scanner.
2433 As a consequence, the relation between the grammar scanner and
2434 parser is much simpler. We can also split "composite tokens" back
2436 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
2437 * src/scan-gram.l (add_column_width, adjust_location): Move to and
2439 * src/location.h, src/location.c (add_column_width)
2440 (location_compute): these.
2441 Fix the column count: the initial column is 0.
2442 (location_print): Be robust to ending column being 0.
2443 * src/location.h (boundary_set): New.
2444 * src/main.c: Adjust to scanner_free being renamed as
2446 * src/output.c: Include scan-code.h.
2447 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
2449 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
2450 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
2451 which is now, again, a separate token.
2452 Adjust all dependencies.
2453 Whereever actions with $ and @ are used, use translate_code.
2454 (action): Remove this nonterminal which is now useless.
2455 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
2456 (grammar_current_rule_action_append): Use translate_code.
2457 (packgram): Bound check ruleno, itemno, and rule_length.

2463 (YY_DECL): Rename as...
2465 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
2466 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
2467 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
2468 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):

2473 * src/scan-gram.l (rule_length, rule_length_overflow)
2474 (increment_rule_length): Remove.
2475 (last_braced_code_loc): Rename as...
2476 (gram_last_braced_code_loc): this.
2477 Adjust to the changes of the parser.
2478 Move all the handling of $ and @ into...
2479 * src/scan-code.l: here.
2480 * src/scan-gram.l (handle_dollar, handle_at): Remove.

2493 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
2495 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
2496 Use Akim's wording from
2497 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
2499 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
2501 Between Bison releases, manually append `+' to the previous Bison
2502 release number, and use that as a signal to automatically print the
2503 ChangeLog's CVS Id keyword from --version. Discussed starting at
2504 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
2505 * ChangeLog: Add Id header.
2506 * configure.ac (AC_INIT): Append `+' to `2.3'.
2507 * src/.cvsignore: Add revision.c.
2508 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
2509 (BUILT_SOURCES): Add revision.c.
2510 (revision.c): New target rule. This file defines a new global variable
2511 named revision. It initializes it with either the Id from ChangeLog
2512 or, if VERSION doesn't contain `+', with the empty string.
2513 * src/getargs.c (version): Print the value of revision.
2514 * src/revision.h: Extern revision.
2516 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2518 * NEWS: Version 2.3.
2519 * configure.ac (AC_INIT): Likewise.
2521 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2523 * data/glr.c (YYRECOVERING): Define to be a function-like macro
2524 with no arguments, not as an object-like macro. This is for
2525 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
2526 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
2527 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
2530 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
2532 * src/getargs.c (usage): Back out yesterday's modification of the
2533 --help output so that we don't have to wait for translation before
2536 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
2538 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
2539 Problem reported by Akim Demaille.
2541 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
2543 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
2545 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
2547 * data/yacc.c (yy_reduce_print): Omit trailing white space in
2548 generated source code. Problem reported by Frans Englich in
2549 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
2551 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
2553 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
2554 shell, not within 'make', so that 'make' by an ordinary builder
2555 (using GNU make) does not worry about configuring gzip. This also
2556 works around a bug reported independently by Keith Thompson and by
2557 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
2558 stderr rather than stdout, messing up the build logs.
2560 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
2562 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
2563 to make sure that YYID will never be unused. This fixes a 'make
2564 maintainer-check' failure caused by the recent changes to the 'Trivial
2565 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
2567 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
2569 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
2571 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
2572 state before an empty RHS is always resolved here. Only the location
2573 of that state is guaranteed to be resolved, and that's enough. This
2574 fixes the remaining bug reported by Derek M. Jones in
2575 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
2576 * tests/glr-regression.at (Uninitialized location when reporting
2577 ambiguity): Test the above case.
2578 Also, the embedded comments in this test case claim it checks the case
2579 of an empty RHS that has inherited the initial location. However, the
2580 corresponding LHS was already resolved, so yyresolveLocations didn't
2581 actually have reason to modify it. Fix this by forcing
2582 nondeterministic operation at the beginning of the parse.
2584 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
2586 * data/c.m4 (b4_yy_symbol_print_generate):
2587 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
2588 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
2589 of the bugs reported today by Derek M Jones in
2590 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
2591 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
2592 defined to be a type name without parens or brackets.
2593 (Location Type): Similarly for YYLTYPE.
2594 * tests/regression.at (Trivial grammars): Put in a test for this
2595 bug that will be caught by 'make maintainer-check' (though not,
2596 alas, by 'make check' unless your compiler is picky).
2598 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
2600 * NEWS: Version 2.2.
2601 * configure.ac (AC_INIT): Likewise.
2603 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
2605 * data/glr.c (yyreportTree): Make room in yystates for the state
2606 preceding the RHS. This fixes the segmentation fault reported by Derek
2608 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
2609 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
2610 to the user. Reported for yyreportTree by Derek M. Jones later in the
2612 * THANKS: Add Derek M. Jones.
2613 Update my email address.
2614 Fix typo in Steve Murphy's name.
2616 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2618 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
2619 checking against YYLAST that caused the parser to miss a potential
2620 alternative in its diagnostic.
2621 Problem reported by Maria Jose Moron Fernandez in
2622 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
2623 * data/lalr1.cc (yysyntax_error_): Likewise.
2624 * data/yacc.c (yysyntax_error): Likewise.
2625 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
2626 tokens, in case we run into an older C compiler.
2627 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
2628 Use them to check for the off-by-one error fixed above.
2630 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
2631 YYSIZE_T, not size_t.
2632 * tests/regression.at (Trivial grammars): New test, to catch
2633 the error fixed by the above patch.
2635 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
2637 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
2639 Reported by Steve Murphy.
2641 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
2643 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
2644 * data/glr.cc: b4_location_flag is now b4_locations_flag.
2646 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
2648 Implement --trace=m4.
2649 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
2650 * src/output.c (output_skeleton): When set, pass -dV to m4.
2652 Factor the handling of flags in m4.
2653 * src/output.c (prepare): Rename the muscle names debug, defines,
2654 error_verbose to debug_flag, defines_flag, error_verbose_flag.
2655 * data/c.m4: Adjust.
2656 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
2657 Use b4_define_flag_if to define other b4_FLAG_if macros.
2658 (b4_location_if): As a consequence, rename as...
2659 (b4_locations_if): this, for consistency.
2660 Adjust all the skeletons.
2662 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
2664 * etc/bench.pm: Shorten bench names.
2666 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
2668 * src/output.h, src/output.c (error_verbose): Move to...
2669 * src/getargs.h, src/getargs.c: here.
2671 Adjust dependencies.
2673 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2675 * data/c.m4 (b4_copyright): Put the special exception for Bison
2676 skeletons here, so we don't have to put it in each skeleton. All
2677 uses changed. Suggested by Akim Demaille. Also, wrap the
2678 copyright notice, in case it is longer than 80 columns. Replace
2679 comma by newline after title.
2681 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2683 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
2684 incompatibility, not a bug. Mention that it wasn't fixed as of
2687 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
2689 * examples/extexi: Enforce the precedence of concatenation over
2691 Reported by Tommy Nordgren.
2693 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
2695 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
2696 with the member "token".
2697 Reported by Martin Nylin.
2699 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
2701 * data/glr.c: Switch to Bison 2.2 special-exception language in
2702 the copyright notice. Use more-regular format for titles and
2704 * data/glr.cc: Likewise.
2705 * data/location.cc: Likewise.
2706 * data/yacc.cc: Likewise.
2707 * doc/bison.texinfo (Conditions): Document this.
2708 * NEWS: likewise. Upgrade version to 2.2.
2710 2006-04-27 Akim Demaille <akim@lrde.epita.fr>
2712 * data/glr.cc: Remove dead code.
2714 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2716 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
2717 that variable and the line breaks the bootstrap. Problem reported
2718 by Juan M. Guerrero.
2720 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
2722 * doc/bison.texinfo (Multiple start-symbols): New.
2724 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
2726 * etc/README, etc/bench.pl: New.
2728 2006-04-03 Akim Demaille <akim@lrde.epita.fr>
2730 * src/scan-gram.l: Be robust to BRACED_CODE appearing before any
2732 Reported by Mickael Labau.
2733 * tests/input.at (Torturing the Scanner): Test it.
2735 2006-03-16 Paul Eggert <eggert@cs.ucla.edu>
2737 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
2738 Problem reported by Bob Rossi.
2740 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
2742 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
2743 and didn't really work.
2744 For the index, use @ifnotinfo, not @iftex.
2745 Minor cleanups of spacing and terminology.
2747 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
2749 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
2750 of AT_NAME_PREFIX when %name-prefix is not used.
2752 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
2754 Apply --prefix to C++ skeletons too: they change the namespace.
2755 The test suite already exercize these cases.
2756 * data/c++.m4 (b4_namespace): New.
2757 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
2758 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
2759 * data/yacc.c, data/glr.c: Remove a useless `[]'.
2760 * doc/bison.texinfo: Document it.
2761 (Option Cross Key): Use @multitable in all formats. It looks
2762 nicer, even in TeX outputs.
2763 (Rules): Use the same code whatever the output type is.
2764 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
2765 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
2766 * tests/calc.at: Use it, instead of hard coding `yy'.

2770 * TODO: Remove dead items.
2772 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
2774 * doc/FAQ: Remove, merged into...
2775 * doc/bison.texinfo (FAQ): this.
2776 * doc/Makefile.am (EXTRA_DIST): Adjust.
2778 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
2780 * data/c.m4 (b4_token_enum): Always define the enum of tokens,
2782 * data/lalrl1.cc, data/glr.cc (parser::token_type): New.
2783 * doc/bison.texinfo (Calc++ Scanner): Use it.
2785 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
2787 Fix two nits reported by twlevo, plus one more that I discovered.
2789 * src/assoc.h (assoc_to_string): Give a name to the arg, as
2790 this is the usual Bison style.
2791 * src/location.h (location_print): Likewise.
2793 * src/reader.h (token_name): Likewise.
2795 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
2797 Fix some nits reported by twlevo.
2798 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
2799 and "POSIX". Use more-modern syntax for URLs. Mention C++
2800 and ask for Java. Don't hardwire OS version numbers. Add
2802 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
2803 * src/conflicts.c (solved_conflicts_obstack): Now static.
2805 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
2807 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
2808 page. Say "you can use it" not "you may use it" as on the web page;
2809 we're describing capabilities not granting permission.
2811 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
2813 * data/glr.c (yyresolveLocations): Rename local variables to avoid
2814 shadowing warnings. Use usual patter for iterating through RHS.
2815 * tests/glr-regression.at
2816 (Uninitialized location when reporting ambiguity):
2817 Modify yylex so that it uses its argument, rather than trying
2818 to rely on ARGSUSED (which doesn't work for gcc with warnings).
2819 const char -> char const.
2821 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
2822 Don't use tabs inside commands; it messes up 'ps'.
2823 Problem reported by twlevo.
2825 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
2827 * tests/glr-regression.at (Uninitialized location when reporting
2828 ambiguity): New test case.
2829 * data/glr.c (yyresolveLocations): New function, which uses
2831 (yyresolveValue): Invoke yyresolveLocations before reporting an
2833 * doc/bison.texinfo (Default Action for Locations): Note
2834 YYLLOC_DEFAULT's usage for ambiguity locations.
2835 (GLR Semantic Actions): Cross-reference those notes.
2837 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
2839 * tests/glr-regression.at (Leaked semantic values when reporting
2840 ambiguity): Remove unnecessary union and type declarations.
2841 (Leaked lookahead after nondeterministic parse syntax error): New test
2843 * data/glr.c (yyparse): Check for zero stacks remaining before
2844 attempting to shift the lookahead so that you don't lose it.
2846 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
2848 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
2849 * tests/glr-regression.at (Leaked semantic values when reporting
2850 ambiguity): New test case.
2851 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
2852 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
2853 now unnecessary yystackp parameter.
2854 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
2855 destructors can be called.
2857 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
2858 in existing testcases.
2860 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
2862 Don't leak semantic values for parent RHS when a user action cuts the
2863 parser, and clean up related code a bit.
2864 * tests/glr-regression.at (Leaked merged semantic value if user action
2865 cuts parse): Rename to...
2866 (Leaked semantic values if user action cuts parse): ... this. Add check
2867 for leaked parent RHS values.
2868 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
2869 between an unresolved state (non-empty chain of semantic options) and
2870 an incomplete one (signaled by an empty chain).
2871 (yyresolveStates): Document the interface. Move all manipulation of a
2872 successfully or unsuccessfully resolved yyGLRState to...
2873 (yyresolveValue): ... here so that yyresolveValue always leaves a
2874 yyGLRState with consistent data and thus is easier to understand.
2875 Remove the yyvalp and yylocp parameters since they are always just
2876 taken from the yys parameter. When reporting a discarded merged value
2877 in debugging output, note that it is incompletely merged. Document the
2879 (yyresolveAction): If resolving any of the RHS states fails, destroy
2880 them all rather than leaking them. Thus, as long as user actions are
2881 written to clean up the RHS correctly, yyresolveAction always cleans up
2882 the RHS of a semantic option. Document the interface.
2884 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
2886 * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that
2887 led to a segmentation fault in GNU Pascal. Problem reported
2890 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
2892 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
2893 mid-rule action inside a nonterminal symbol in order to declare a
2894 destructor for its semantic value.
2896 2006-02-16 Paul Eggert <eggert@cs.ucla.edu>
2898 * data/yacc.c [(! defined yyoverflow || YYERROR_VERBOSE) && !
2899 YYSTACK_USE_ALLOCA && ! defined YYSTACK_ALLOC && defined
2900 __cplusplus && ! defined _STDLIB_H && !
2901 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||
2902 defined free))]: Include <stdlib.h> rather than rolling our own
2903 declarations of malloc and free, to avoid problems with
2904 incompatible declarations (using 'throw') C++'s stdlib.h. This
2905 should fix Debian bug 340012

2917 * NEWS: Version 2.1a.
2918 * tests/headers.at (AT_TEST_CPP_GUARD_H): Declare yyerror and yylex,
2919 since C99 requires this.
2921 2006-02-11 Paul Eggert <eggert@cs.ucla.edu>
2923 * m4/c-working.m4: New file.
2924 * configure.ac (BISON_TEST_FOR_WORKING_C_COMPILER): Use it.
2926 2006-02-10 Paul Eggert <eggert@cs.ucla.edu>

2932 More portability fixes for problems summarized by Nelson H. F. Beebe.
2934 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Catch a
2935 configuration screwup "./configure CC=/opt/SUNWspro/bin/c89
2936 CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
2937 LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this

2943 More portability fixes for problems summarized by Nelson H. F. Beebe.
2945 * doc/bison.texinfo (Calc++ Scanner): Work around a bug in flex
2946 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
2948 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
2949 nodist_PROGRAMS, since we don't need to actually compile the
2950 example if we're just doing a plain 'make'. This avoids bothering
2951 the installer unnecessarily about problems due to weird C++

2956 More portability fixes for problems summarized by Nelson H. F. Beebe.
2958 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
2959 than #include "...", and compile with -I'.'. The old method was
2960 not portable, according to Posix and the C standard, and it does
2961 not work with Sun C 5.7, where previous #line directives affect
2962 the working directory used in later #include "..." directives.

2981 that '#include <string>' works.
2983 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
2984 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
2985 "warning: sorry: semantics of inline function static data `const
2986 unsigned char translate_table[262]' are wrong (you'll wind up with
2989 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
2990 or, xor to not_, and_, or_, and xor_, respectively. This works
2991 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
2992 random system header somewhere that includes the equivalent of

3001 During deterministic GLR operation, user actions should be able to
3002 influence the parse by changing yychar. To make this easier to fix and
3003 to make glr.c easier to evolve in general, don't maintain yytoken in
3004 parallel with yychar; just compute yytoken when needed.
3005 * tests/glr-regression.at (Incorrect lookahead during deterministic
3006 GLR): Check that setting yychar in a user action has the intended
3008 * data/glr.c (yyGLRStack): Remove yytokenp member.
3009 (yyclearin): Don't set *yytokenp.
3010 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
3011 yychar rather than *yytokenp to determine the current lookahead.
3012 Compute yytoken locally when needed.
3013 (yyparse): Likewise. Remove the local yytoken that yytokenp used to

3017 after `--report' documentation.

3031 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
3032 got from <http://bro-ids.org/download.html>. The bug is that
3033 when two actions appeared in succession, the second one was
3034 scanned before the first one was added to the grammar rule
3035 as a midrule action. Bison then output the incorrect warning
3036 "parse.y:905.17-906.36: warning: unused value: $3".
3037 * src/parse-gram.y (BRACED_CODE, action): These are no longer
3038 associated with a value.
3039 (rhs): Don't invoke grammar_current_rule_action_append.
3040 (action): Invoke it here instead.
3041 * src/reader.c (grammar_midrule_action): Now extern.
3042 (grammar_current_rule_action_append): Don't invoke
3043 grammar_midrule_action; that is now the scanner's job.
3044 * src/reader.h (last_string, last_braced_code_loc):
3045 (grammar_midrule_action): New decls.
3046 * src/scan-gram.l (last_string): Now extern, sigh.
3047 (last_braced_code_loc): New extern variable.
3048 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
3049 rule already has an action.
3050 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
3051 * tests/input.at (AT_CHECK_UNUSED_VALUES):
3052 Add some tests to check that the above changes fixed the bug.
3054 2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
3056 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
3057 All used changed. Check whether the symbol has a destructor,
3058 not whether it is typed.
3059 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
3060 that the values are still reported as unused. All line numbers

3074 Work around a bug in Pike 7.0, and give the Pike folks a
3075 better way to override the usual int widths.

3077 user can override the types.
3078 (short): #undef, to work around a bug in Pike 7.0.
3079 (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types.
3080 (union yyalloc.yyss): Use yytype_int16 rather than short.
3082 (yysigned_char): Remove.
3083 * src/parse-gram.y (YYTYPE_UINT8, YYTYPE_INT8, YYTYPE_UINT16):
3084 (YYTYPE_INT16): New macros, to test the new facility in yacc.c.

3104 2006-01-21 Paul Eggert <eggert@cs.ucla.edu>

3107 since we don't want to insist on a version number at the start
3108 of the changelog every time.
3109 * Makefile.maint: Sync from coreutils a bit better.
3110 (sc_trailing_blank): Renamed from sc_trailing_space.
3112 (sc_no_if_have_config_h, sc_require_config_h):
3113 (sc_prohibit_assert_without_use): New rules.

3298 in the yychar entry.
3299 In the yychar entry, remove mention of the local yychar case (pure
3300 parser) since this is irrelevant information when writing semantic
3301 actions and since it's already discussed in `Bison Symbols' where
3302 yychar is otherwise described as an external variable.
3303 In the yychar entry, don't call it the `current' look-ahead since it
3304 isn't when semantic actions are deferred.
3305 In the yychar and yyclearin entries, add note about deferred semantic
3307 Add yylloc and yylval entries discussing look-ahead usage.
3308 (Look-Ahead Tokens): When discussing yychar, don't call it the

3337 yyaddDeferredAction.

3348 (Incorrect lookahead during deterministic GLR): New test case.
3349 (Incorrect lookahead during nondeterministic GLR): New test case.
3351 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>

3363 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
3365 * data/glr.c (yyresolveValue): When merging semantic options, if at
3366 least one user action succeeds but a later one cuts the parse, then
3367 destroy the semantic value before returning rather than leaking it.
3368 (yyresolveStates): If a user action cuts the parse and thus
3369 yyresolveValue fails, ignore the (unset) semantic value rather than
3370 corrupting the yyGLRState, and empty the semantic options list since
3371 the user actions should have called all necessary destructors.
3372 Simplify code with YYCHK.
3373 * tests/glr-regression.at (Corrupted semantic options if user action
3374 cuts parse): New test case.
3375 (Undesirable destructors if user action cuts parse): New test case.
3376 Before applying any of this patch, this test case never actually failed
3377 for me... but only because the corrupted semantic options usually

3427 Warn about dubious constructions like "%token T T".
3429 * src/symtab.h (struct symbol.declared): New member.

3623 * data/yacc.c (yylen): Initialize to 0.
3624 Keep its value to the number of items to possibly shift.
3625 In particular, a regular successful parse that ends on YYFINAL by
3626 a (internal) YYACCEPT must not have yylen != 0.
3627 (yyerrorlab, yyreturn): Pop the RHS.
3628 Reorder a bit to emphasize the `shifting' bits of code.
3629 (YYPOPSTACK): Now accept a number of items to pop.

3639 * djgpp/config.bat: Replace every occurence of the file name
3640 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
3641 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
3642 * djgpp/config.sed: Replace every occurence of the file name
3643 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with

3649 using djunpack.bat and fnchange.lst.
3651 2005-12-12 Paul Eggert <eggert@cs.ucla.edu>
3653 * bootstrap (build_cvs_prefix): Remove; unused.
3654 (CVS_PREFIX): Adjust to yesterday's Savannah reorganization
3655 when getting gnulib.

3672 * tests/sets.at (Accept): Fix typos in regular expression used to
3673 sed out the final state number.
3675 Work around portability problem on Solaris 10: flex-generated
3676 files include <stdio.h> before <config.h>, which messes up
3677 because the latter defines __EXTENSIONS__. Address the problem
3678 by creating two new little files that include <config.h> first,
3679 then include the flex-generated files. Rewrite everyone else
3680 to include <config.h> first, as well.
3681 * lib/timevar.c: Always include "config.h".
3682 * src/Makefile.am (bison_SOURCES): Replace scan-gram.l with

3725 All uses of /*CONSTCOND*/0 replaced by YYID(0).
3726 * data/yacc.c: Likewise.
3727 * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
3728 (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
3729 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
3731 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
3732 * data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
3733 Use YYID(0) rather than 0, for lint.
3734 (yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.

3755 * NEWS: Document the following change.
3756 * data/yacc.c: Say "parser skeleton" rather than "file", since
3757 it's no longer just a file.
3758 * data/glr.c: Grant a special exception for C GLR parsers, that
3759 reads like the already-existing exception for C LALR(1) parsers.

3761 * data/lalr1.cc: Likewise.
3762 * data/location.cc: Likewise.

3775 * tests/calc.at (_AT_CHECK_CALC,_AT_CHECK_CALC_ERROR):
3776 Don't check NUM-STDERR-LINES, since the output format is fluctuating.
3777 We can revert this once things settle down.
3779 * src/conflicts.c (conflicts_print): Don't print file name twice
3780 when %expect fails because there were no conflicts.
3781 * doc/bison.texinfo (Expect Decl): Tighten up wording in previous

3853 Have glr.c include its header file when created.

4020 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
4022 Undo the parts of the unlocked-I/O change that substituted
4023 putc or puts for printf. This might hurt performance a bit,
4024 but some people prefer the printf style.

4055 Use unlocked I/O for a minor performance improvement on hosts like
4056 GNU/Linux and Solaris that support unlocked I/O. The basic idea
4057 is to use the gnlib unlocked-io module, and to prefer putc and
4058 puts to printf when either will work (since the latter doesn't
4059 come in an unlocked flavor).
4060 * bootstrap (gnulib_modules): Add unlocked-io.

4126 * lib/subpipe.c: New function end_of_output_subpipe() added
4127 to allow support for non-posix systems. This is a no-op function
4130 * lib/subpipe.h: New function end_of_output_subpipe() added
4131 to allow support for non-posix systems. This is a no-op function
4134 * src/output.c (output_skeleton): Use end_of_output_subpipe() to
4135 handle the lack of pipe/fork functionality on non-posix systems.

4203 (yysyntax_error_): Takes the state number as argument.
4204 (yyreduce_print_): Use the argument yyrule, not the former
4207 2005-09-26 Paul Eggert <eggert@cs.ucla.edu>

4219 local variables whose names begin with 'yy'.
4220 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
4221 Trivial changes from Joel E. Denny.
4223 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
4225 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
4226 don't use alloca any more.
4228 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
4229 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
4230 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
4231 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
4232 to match yacc.c, to test more hosts.
4234 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
4236 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
4237 doesn't affect behavior.
4238 (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
4240 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
4241 This works a bit better with glibc, if user code has already included
4243 * doc/bison.texinfo (Bison Parser): Document that users can't
4244 arbitrarily use malloc and free for other purposes. Document
4245 that <alloca.h> and <malloc.h> might be included.
4246 (Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the
4247 user must declare alloca.

4256 2005-09-19 Paul Eggert <eggert@cs.ucla.edu>
4258 * data/yacc.c (YYSIZE_MAXIMUM): New macro.
4259 (YYSTACK_ALLOC_MAXIMUM): Use it.
4260 (yysyntax_error): New function.
4261 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
4262 multiple syntax errors are reported, and alloca is being used.
4263 Instead, reallocate buffers twice as big each time, so that
4264 we waste at most half the allocated memory. Start with a small
4265 (128-byte) buffer that will suffice in most cases anyway.
4266 Use yysyntax_error to do most of the work.
4268 * doc/bison.texinfo (Error Reporting, Table of Symbols):
4269 yynerrs is the number of errors reported, not the number of
4272 * tests/glr-regression.at (Duplicated user destructor for lookahead):
4273 Mark it as expected to fail.
4274 Cast result of malloc; problem reported by twlevo@xs4all.nl.
4275 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
4276 Don't start user-code symbols with "yy", to avoid name space problems.
4278 2005-09-19 Akim Demaille <akim@epita.fr>
4280 Remove the traits, failed experiment.
4281 It never proved useful, and anyway because of the current
4282 definition, it was not possible to have several specialization of
4283 this traits, making it useless.
4284 * data/lalr1.cc (yy:traits): Remove.
4285 Inline its definitions in the parser class.
4287 2005-09-19 Akim Demaille <akim@epita.fr>

4309 * src/output.c (prepare): Likewise.
4310 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
4311 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
4312 is not defined. This is an awful hack, but it's enough for now.
4313 All callers changed.
4314 * tests/glr-regression-at (make_value): Args are const pointers now,
4315 to avoid GCC warning.
4316 (Duplicated user destructor for lookahead): New test. Currently
4317 skipped. It fails on my host but I'm not sure it'll always fail.
4319 2005-09-16 Akim Demaille <akim@epita.fr>
4321 * src/symtab.h (struct symbol): Declare the printer and destructor
4322 as const, to avoid accidental calls to free.
4323 (symbol_destructor_set, symbol_printer_set): Adjust.
4324 * src/symtab.c: Adjust.
4326 2005-09-16 Akim Demaille <akim@epita.fr>
4328 * data/c.m4 (b4_token_enums): New.
4329 (b4_token_defines): Rename as...
4330 (b4_token_enums_defines): this.
4331 (b4_token_defines): New, output only the #defines.
4332 * data/yacc.c, data/glr.c: Adjust.
4333 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
4334 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
4337 2005-09-16 Akim Demaille <akim@epita.fr>
4339 * data/lalr1.cc (yylex_): Remove, inline its code.
4340 (yyreport_syntax_error_): Remove, replaced by...
4341 (yysyntax_error_): this which returns a string and leaves to the
4342 caller the call to the users' error function.
4343 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
4344 Move from members of the parser object...
4345 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
4346 to local variables of the parse function.
4348 2005-09-16 Akim Demaille <akim@epita.fr>
4350 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
4351 since it's in Bison's name space.
4353 2005-09-15 Paul Eggert <eggert@cs.ucla.edu>
4355 * data/glr.c (yyresolveValue): Add default case to pacify
4356 gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl.
4358 * NEWS: Document when yyparse started to return 2.
4359 * doc/bison.texinfo (Parser Function): Document when yyparse
4362 * data/lalr1.cc: Revert part of previous change, as it's incompatible.
4363 (b4_filename_type): Renamed back from b4_file_name_type. All uses
4365 (class position): file_name -> filename (reverting). All uses changed.
4367 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
4369 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
4370 do anything if $@ exists. This reverts part of the 2005-07-07
4373 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
4375 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
4376 contains obsolete information and isn't worth distributing as a
4377 separate file anyway.
4378 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
4379 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
4380 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
4381 (yyparse): Abort if user code uses longjmp to throw an unexpected
4384 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
4386 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
4387 Suggested by twlevo@xs4all.nl.
4389 * data/glr.c (YYCHK1): Do not assume YYE is in range.
4390 This avoids a diagnostic from gcc -Wswitch-enum.
4391 Problem reported by twlevo@xs4all.nl.
4393 * doc/bison.texinfo: Don't use "filename", as per GNU coding
4394 standards. Use "file name" or "file" or "name", depending on
4396 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
4397 not to hack/foo.tab.c.
4398 (Calc++ Top Level): 2nd arg of main is not const.
4399 * data/glr.c: b4_filename -> b4_file_name.
4400 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.

4417 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
4419 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
4422 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
4424 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
4425 All uses changed. Invoke user destructor after an error during a
4426 split parse (trivial change from Joel E. Denny).
4428 * tests/glr-regression.at
4429 (User destructor after an error during a split parse): New test case.
4430 Problem reported by Joel E. Denny in:
4431 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
4433 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
4435 * README-cvs: Give URLs for recommended tools.
4436 Mention Gzip version problem, and bootstrapping issues.
4437 Remove troubleshooting section, as it's somewhat obsolete.
4439 * bootstrap (no_cache): New var, to accommodate different wget
4440 variants. Use it instead of '-C off'. Problem reported by
4443 * data/glr.c (yydestroyStackItem): New function.
4444 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
4445 debugging information. Problem reported by Joel E. Denny.

4455 * tests/glr-regression.at
4456 (User destructor for unresolved GLR semantic value): New test case.
4457 Problem reported by Joel E. Denny in:
4458 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
4460 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
4462 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
4464 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
4465 lib-prefix.m4, po.m4.
4467 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
4468 in yydestruct diagnostic, since it might not be an error.
4469 Problem reported by Joel Denny near end of
4470 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
4471 * data/lalr1.cc (yyerturn): Likewise.
4472 * data/yacc.c (yyreturn): Likewise.
4473 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
4475 * src/files.c: Remove obsolete FIXME comment.
4477 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
4478 with the other templates, and to fix bogus run-on messages such
4479 as the one reported at the end of
4480 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
4481 All callers changed to avoid the newline.
4482 (yyprocessOneStack): Output two lines rather than one, to accommodate
4483 the above change. This changes the debug output format slightly.
4485 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
4486 reported by Joel E. Denny in
4487 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
4489 * tests/glr-regression.at (Duplicate representation of merged trees):
4490 New test, from Joel E. Denny in:
4491 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
4492 * THANKS: Add Joel E. Denny.
4494 * configure.ac (AC_INIT): Bump to 2.0c.
4496 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
4498 * NEWS: Version 2.0b.
4500 * Makefile.am (SUBDIRS): Put examples before tests, so that
4501 "make check" doesn't finish with "All 1 tests passed".
4503 * tests/regression.at (Token definitions): Don't rely on
4504 AT_PARSER_CHECK for data that contains backslashes. It currently
4505 uses 'echo', and 'echo' isn't portable if its argument contains
4506 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
4507 that the byte '\0xff' is not printable in the C locale; it is,
4508 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
4509 not printable, so use '\0x81' to test.
4511 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
4512 version of GCC, since the macro is used with non-GCC compilers.
4514 Fix core dump reported by Pablo De Napoli in
4515 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
4516 * tests/regression.at (Invalid inputs with {}): New test.
4517 * src/parse-gram.y (token_name): Translate type before using
4520 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
4521 the user's name space. All uses changed to __attribute__
4523 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
4524 Add __attribute__ ((__noreturn__)).
4526 * etc/clcommit: Remove. We weren't using it, and it failed
4527 "make maintainer-distcheck".
4528 * Makefile.maint: Merge from coreutils.
4529 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
4530 (syntax-check-rules): Change list of rules as described below.
4531 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
4532 (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):
4533 (sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope):
4534 (sc_trailing_space): New rules.
4535 (sc_xalloc_h_in_src): Remove.
4536 (sc_cast_of_argument_to_free, sc_cast_of_x_alloc_return_value):
4537 (sc_space_tab, sc_error_exit_success, sc_changelog):
4538 (sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
4539 (makefile-check, po-check, author_mark_check):
4540 (makefile_path_separator_check, copyright-check):
4541 Use grep -n, to make it easier to find violations.
4542 Use CVS_LIST and CVS_LIST_EXCEPT.
4543 (header_regexp, h_re): Remove.
4545 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
4546 (my-distcheck): Use more-modern GCC flags.
4547 (signatures, %.asc): Remove.
4548 (rel-files, announcement): Remove signatures.
4549 Restore old updating code, even though we don't use it, so
4550 that we're the same as coreutils.
4551 (alpha, beta, major): Depend on news-date-check.
4552 Make the upload commands.
4554 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
4555 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
4556 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
4557 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.
4558 * src/Makefile.am, src/gram.c, src/muscle_tab.h: Likewise.
4559 * src/parse-gram.y, src/system.h, src/tables.c, src/vcg.c: Likewise.
4560 * src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise.
4561 * tests/sets.at: Likewise.
4563 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
4564 we comment out the Autoconf version number.
4565 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
4566 it's error-prone and "make maintainer-distcheck" rejects it.
4568 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
4569 Indent calls to "error" to pacify "make maintainer-distcheck",
4570 when the calls are not intended to be translated.
4571 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
4573 * src/Makefile.am (DEFS): Use +=, to pacify
4574 "make maintainer-distcheck".
4575 (bison_SOURCES): Add scan-skel.h.
4576 (sc_tight_scope): New rule, from coreutils.
4578 * src/files.c (src_extension, header_extension):
4579 Now static, not extern.
4580 * src/getargs.c (short_options): Likewise.
4581 * src/muscle_tab.c (muscle_table): Likewise.
4582 * src/parse-gram.y (current_class, current_type, current_prec):
4584 * src/reader.c (grammar_end, previous_rule_end): Likewise.
4585 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
4586 * src/main.c (main): Cast bindtextdomain and textdomain calls to
4587 void, to avoid warning when NLS is disabled.
4588 * src/output.c: Include scan-skel.h.
4589 (scan_skel): Remove decl, since scan-skel.h does this.
4591 Indent calls to "error" to pacify "make maintainer-distcheck".
4592 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
4593 * src/reader.h (gram_end, gram_lineno): New decls to pacify
4594 "make maintainer-distcheck".
4595 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
4596 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
4597 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
4598 (skel_lex_destroy, scan_skel): Move these decls to...
4599 * src/scan-skel.h: New file.
4600 * src/uniqstr.c (uniqstr_assert):
4601 Indent calls to "error" to pacify "make maintainer-distcheck".
4603 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
4606 * tests/torture.at: Revamp to avoid misuse of atoi that
4607 "make maintainer-distcheck" complained about.
4609 * examples/extexi (message): Don't print a message more than once,
4610 and omit line-number decoration that makes Emacs compile think
4611 that informative messages are worth worrying about.
4613 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
4615 * configure.ac: Update version number.
4617 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
4619 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
4620 autogenerated by the maintainer.
4621 * examples/calc++/.cvsignore: Add *.yy.
4623 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
4624 * lib/bitset_stats.c (bitset_stats_init): Likewise.
4625 * lib/bitsetv.c (bitsetv_alloc): Likewise.
4627 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
4629 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
4630 from maintainer-distcheck about casting the argument of 'free'.
4632 * NEWS: Mention recent yytname changes.
4633 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
4635 * bootstrap: For translations that have not yet been upgraded to
4636 the new runtime-po domain, prime the pump by extracting the
4637 relevant strings from the obsolete translations. This code can be
4638 removed once the bison-runtime domain has been translated by each
4641 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
4642 now that token names are already quoted.
4644 Fix problem reported by Anthony Heading.
4645 * data/glr.c (YYTOKEN_TABLE): New macro.
4646 (yytname): Define if YYTOKEN_TABLE.
4647 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
4648 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
4649 (YYERROR_VERBOSE): Define the same way the other skeletons do.
4650 * src/output.c (prepare_symbols): Output token_table_flag.
4652 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
4654 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
4655 again if the first call fails.
4657 * data/glr.c (yytnamerr): New function.
4658 (yyreportSyntaxError): Use it to dequote most string literals.
4659 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
4660 with other skeletons. All uses changed.
4661 (yytnameerr_): New function.
4662 (yyreport_syntax_error): Use it to dequote most string literals.
4663 * data/yacc.c (yytnamerr): New function.
4664 (yyerrlab): Use it to decode most string literals.
4665 * doc/bison.texinfo (Decl Summary, Calling Convention):
4666 Clarify quoting convention of yytname.
4667 * src/output.c (prepare_symbols): Quote all names. This undoes
4668 the 2005-04-17 change, which is now accomplished (mostly) via
4669 changes in the parsers as described above.
4670 * tests/regression.at (Token definitions, Web2c Actions):
4671 Undo most 2005-04-17 change here, too.
4673 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
4675 Fix more problems reported by twlevo@xs4all.nl.
4676 * tests/cxx-type.at: Don't pipe output of ./types through sed to
4677 remove trailing spaces. This loses the exit status of ./types,
4678 and isn't needed since ./types shouldn't be emitting trailing
4680 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
4681 as the stack isn't valid in that case.
4683 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
4684 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
4685 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
4686 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
4688 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
4689 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
4690 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
4693 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
4694 overly-picky compilers that reject 'char *foo = "bar";'.
4696 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
4697 to FILE * parameter, not to stderr. This fixes a typo introduced
4698 in the 2005-07-12 change.
4700 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
4701 warnings from GCC 4.
4703 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
4704 (yyglrShiftDefer, yysplitStack):
4705 Remove unused parameters b4_pure_formals. All uses changed.
4706 (yyglrShift): Remove unused parameters b4_user_formals.
4708 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
4710 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
4712 Destructor cleanups and regularization among the three skeletons.
4713 * NEWS: Document the behavior changes.
4714 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
4715 stack before failing, as the cleanup code will do it for us now.
4716 * data/lalr1.cc (yyerrlab): Likewise.
4717 * data/glr.c (yyparse): Pop everything off the stack before
4718 freeing it, so that destructors get called properly.
4719 * data/lalr1.cc (yyreturn): Likewise.
4720 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
4721 This is more consistent.
4722 * doc/bison.texinfo (Destructor Decl): Mention more reasons
4723 why destructors might be called. 1.875 -> 2.1.
4724 (Destructor Decl, Decl Summary, Table of Symbols):
4725 Some English-language cleanups for %destructor.
4726 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
4727 Add output line for destructor of start symbol.
4728 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
4729 because of that same extra output line.
4731 * NEWS: Document minor wording changes in diagnostics of
4732 Bison-generated parsers.
4733 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
4734 Remove unused formals. All uses changed.
4735 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
4736 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
4737 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
4738 Rename yyoverflowab to yyexhaustedlab.
4739 When memory exhaustion occurs during syntax-error reporting,
4740 report it separately rather than in a single diagnostic; this
4742 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
4743 (Memory Exhausted): Renamed from Parser Stack Overflow.
4744 Revamp wording slightly to prefer "memory exhaustion".
4745 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
4747 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
4749 Add i18n support to the GLR skeleton. Partially fix the C++
4750 skeleton; a C++ expert needs to finish this. Remove debugging
4751 msgids; there's little point to having them translated, since they
4752 can be understood only by someone who can read the
4753 (English-language) source code.
4755 Generate runtime-po/bison-runtime.pot automatically, so that we
4756 don't have to worry about garbage getting in that file. We'll
4757 make sure after the next official release that old msgids don't
4759 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
4761 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
4763 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
4764 Fix typos in explanations of the runtime file.
4765 * bootstrap: Change gettext keyword from YYI18N to YY_.
4766 Use standard Makefile.in.in in runtime-po, since we'll arrange
4767 for backward-compatible bison-runtime.po files in a different way.
4768 * data/glr.c (YY_): New macro, from yacc.c.
4769 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
4770 Translate messages intended for users.
4771 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
4772 the wording in the other skeletons. We don't know that the memory
4774 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
4775 Use same method that yacc.c uses.
4776 Don't translate debugging messages.
4777 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
4778 it doesn't work (yet), and requires C++ expertise to fix.
4779 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
4780 Move defn to a more logical place, to be consistent with other
4782 Don't translate debugging messages.
4783 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
4784 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
4785 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
4786 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
4788 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
4789 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
4791 * tests/glr-regression.at (Badly Collapsed GLR States):
4793 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
4794 yylex should return 0 at EOF rather than aborting.
4796 Improve tests for stack overflow in GLR parser.
4797 Problem reported by twlevo@xs4all.nl.
4798 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
4800 (yyStackOverflow): Just longjmp, but with value 2 so that caller
4801 can handle the problem.
4802 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
4803 (yyparse): New local variable yyresult to record the result.
4804 Use result of setjmp to set it, rather than storing itinto
4806 (yyDone): Remove label.
4807 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
4808 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
4809 if YYABORT is used).
4810 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
4811 yyparse status; put status > 1 into diagnostic.
4812 Check that status==2 works.
4813 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
4814 Use exit status 3 for failure to open (which shouldn't happen).
4816 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
4818 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
4819 1 on syntax error; just let yyparse do its thing.
4820 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
4821 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
4822 (Exploding the Stack Size with Alloca):
4823 (Exploding the Stack Size with Malloc):
4824 Expect exit status 2, not 1, since the parser is supposed to blow
4825 its stack. Problem reported by twlevo@xs4all.nl.
4827 * data/glr.c (yyparse): Don't assume that the initial calls
4828 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
4829 Print a stack-overflow message and fail instead.
4830 Initialize the line-number information before creating the stack,
4831 so that the stack-overflow message can report line zero safely.
4833 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
4835 Fix problems reported by twlevo@xs4all.nl.
4836 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
4837 (yyuserMerge): Provide a default case if b4_mergers is empty.
4838 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
4839 * tests/glr-regression.at
4840 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
4841 Add casts to pacify C++ compilers.
4842 * tests/glr-regression.at (Improper merging of GLR delayed action
4843 sets): Declare yylex before using it.
4844 * tests/Makefile.am (maintainer-check-g++): Fix a stray
4845 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
4846 test for valgrind; valgrind is independent of g++.
4847 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
4848 for compatibility with POSIX 1003.1-2001 (if running coreutils).
4849 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
4850 Use a destructor, so that we can expand the stack. Change
4851 YYSTYPE to char * so that we can free it. Cast result of malloc.
4853 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
4855 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
4856 a valgrind failure. Problem reported by twlevo@xs4all.nl.
4858 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
4860 * PACKAGING: New file, suggested by Bruno Haible and taken from
4861 similar wording in gettext's PACKAGING file.
4862 * NEWS: Mention PACKAGING.
4863 * Makefile.am (EXTRA_DIST): Add PACKAGING.
4865 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
4867 * NEWS: Document recent i18n improvements.
4868 * bootstrap: Get runtime translations into runtime-po.
4869 Create runtime-po files automatically, if possible.
4870 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
4871 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
4872 does not infringe on the user's name space.
4873 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
4874 * doc/bison.texinfo (Internationalization): Revamp the English
4875 and Texinfo syntax a bit, to try to make it clearer.
4876 (Bison Options, Option Cross Key): Mention --print-localedir.
4877 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
4878 YYENABLE_NLS. Quote a bit more.
4879 * runtime-po/.cvsignore: New file.
4880 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
4881 * runtime-po/Rules-quot: Remove; now created by bootstrap.
4882 * runtime-po/quot.sed: Likewise.
4883 * runtime-po/boldquot.sed: Likewise.
4884 * runtime-po/en@quot.header: Likewise.
4885 * runtime-po/en@boldquot.header: Likewise.
4886 * runtime-po/insert-header.sin: Likewise.
4887 * runtime-po/remove-potcdate.sin: Likewise.
4888 * runtime-po/Makevars: Likewise.
4889 * runtime-po/LINGUAS: Likewise.
4890 * runtime-po/de.po: Likewise; we will rely on the translation project
4891 to maintain this, so "bootstrap" should get it.
4892 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
4894 * src/main.c (main): Bind the bison-runtime domain, too.
4896 2005-07-12 Bruno Haible <bruno@clisp.org>
4898 * data/yacc.c: Include <libintl.h> when NLS is enabled.
4899 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
4900 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
4901 * runtime-po: New directory.
4902 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
4903 $(DOMAIN).pot-update rule, so that old messages are never dropped.
4904 * runtime-po/Rules-quot: New file, copied from po/.
4905 * runtime-po/quot.sed: Likewise.
4906 * runtime-po/boldquot.sed: Likewise.
4907 * runtime-po/en@quot.header: Likewise.
4908 * runtime-po/en@boldquot.header: Likewise.
4909 * runtime-po/insert-header.sin: Likewise.
4910 * runtime-po/remove-potcdate.sin: Likewise.
4911 * runtime-po/Makevars: New file.
4912 * runtime-po/POTFILES.in: New file.
4913 * runtime-po/LINGUAS: New file.
4914 * runtime-po/bison-runtime.pot: New file.
4915 * runtime-po/de.po: New file.
4916 * m4/bison.m4: New file.
4917 * Makefile.am (SUBDIRS): Add runtime-po.
4918 (aclocaldir, aclocal_DATA): New variables.
4919 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
4921 * src/getargs.c (usage): Document --print-localedir option.
4922 (PRINT_LOCALEDIR_OPTION): New enum item.
4923 (long_options): Add --print-localedir option.
4924 (getargs): Handle --print-localedir option.
4925 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
4926 (Internationalization): New section.
4928 2005-07-12 Akim Demaille <akim@epita.fr>
4930 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
4931 for consistency with the rest of the code.
4932 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
4935 2005-07-12 Akim Demaille <akim@epita.fr>
4937 * src/parse-gram.y: Use %printer instead of YYPRINT.
4939 2005-07-12 Akim Demaille <akim@epita.fr>
4941 * src/symtab.h, src/symtab.c (symbol_print): New.
4942 * src/symlist.h, src/symlist.c (symbol_list_print): New.
4943 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
4945 2005-07-12 Akim Demaille <akim@epita.fr>
4947 * data/glr.c (b4_syncline): Fix (swap) the definitions of
4948 b4_at_dollar and b4_dollar_dollar.
4950 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
4952 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
4953 and Pennello's paper.
4955 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
4957 * data/yacc.c (yyparse): Undo previous patch. Instead,
4958 set yylsp[0] and yyvsp[0] only if the initial action
4959 sets yylloc and yylval, respectively.
4961 * data/yacc.c (yyparse): In the initial action, set
4962 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
4963 This avoids the use of undefined variables if the initial
4964 action does not set yylloc and/or yylval.
4966 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
4968 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
4969 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
4970 Remove from CVS. These files are automatically generated.
4971 * examples/extexi: Clarify that this file is now part of Bison,
4972 not GNU M4, and that it works with any POSIX-compatible Awk.
4973 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
4974 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
4975 so that we also get calc++-parser.yy. Geneate it.
4976 Use $(AWK), not gawk, since any conforming Awk will do.
4977 Put comment before action, since older 'make' can't handle comment
4979 $(BUILT_SOURCES): List all built sources, not just some of them.
4980 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
4981 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
4982 $($(calc_sources_generated)): Remove unnecessary test for existence
4983 of target. (This had a shell syntax error anyway; a stray "x".)
4984 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
4986 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
4988 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
4989 implied by the other modules.
4991 2005-07-06 Akim Demaille <akim@epita.fr>
4993 Bind examples/calc++ to the package.
4994 * examples/calc++/Makefile: Remove, replaced by...
4995 * examples/calc++/Makefile.am: ... this new file.
4996 * examples/calc++/test: Remove input.
4997 * examples/calc++/compile: Remove.
4998 * examples/Makefile.am: New.
4999 * configure.ac, Makefile.am: Adjust.
5000 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
5002 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
5004 * data/glr.c (yyFail): Drastically simplify; since the format argument
5005 never had any % directives, we can simply pass it to yyerror.
5006 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
5007 be modified later, as that is the usual style in glr.c.
5008 Problems reported by Paul Hilfinger.
5010 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
5011 and size overflow errors.
5012 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
5013 in case the user prolog sets feature-test macros like _GNU_SOURCE.
5014 (YYSIZEMAX): New macro.
5015 (yystpcpy): New function, taken from yacc.c.
5016 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
5017 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
5018 so that we don't have to maintain their signatures.
5019 (yyFail): Check for buffer overflow, by using vsnprintf rather
5020 than vsprintf. Allocate a bigger buffer if possible.
5021 Report an error if buffer allocation fails.
5022 (yyStackOverflow): New function.

5030 Don't assume stack number fits in int.
5031 (yysplitStack): Check for storage allocation failure.
5032 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
5033 can print diagnostics on storage allocation failure. All callers
5035 (yyresolveValue): Use yybool for boolean.

5074 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
5075 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
5076 which stems from the 2005-05-27 patch.
5078 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
5080 * data/glr.c: Modify treatment of unused parameters to permit use

5093 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
5095 Fix infringement on user name space reported by Bruno Haible.
5096 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
5097 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
5098 the user's name space.
5099 (alloca): Include <stdlib.h> to get it, if it's not built in.
5100 (YYMALLOC, YYFREE): Define only if needed.
5101 (malloc, free): Declare, but only if needed, as this infringes on
5102 the user name space.
5104 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
5106 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
5107 * lib/bitset.c (bitset_print): Don't assume size_t can be printed

5122 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
5124 * bootstrap: Remove workaround for problem I encountered with
5125 gettext 0.14.1; it seems to be fixed now.

5129 * NEWS: Version 2.0a.
5131 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
5132 the previous change.
5134 Various maintainer cleanups.
5135 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
5136 conftest*, for benefit of CVS commands run at the same time as
5137 "configure". Add build-aux, since "bootstrap" now creates it and
5139 * Makefile.cfg (move_if_change): Remove.
5140 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
5141 (ftp-gnu, www-gnu, move_if_change, local_updates, update):

5150 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
5151 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
5152 ylwrap. These files now go into build-aux.
5153 * config/move-if-change: Remove.
5154 * config/prev-version.txt: Bump from 1.75 to 2.0.

5160 fopen-safer.c, stdio-safer.h, unistd-safer.h.
5161 * lib/subpipe.c: Include "unistd-safer.h".
5162 (create_subpipe): Make sure all the newly-created
5163 file descriptors are > 2, so that diagnostics don't
5164 get sent down them (which might cause Bison to hang, in theory).
5165 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
5166 * src/files.c (xfopen): Use fopen_safer, not fopen.
5168 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
5169 yesterday's yacc.c fix.
5171 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>

5178 don't set yychar to EMPTY.
5179 (yyoverflowlab): Don't call destructor.
5180 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
5181 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
5182 since we no longer output the message "discarding lookahead token
5185 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
5187 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
5188 fix a small glitch in debugging output.
5189 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
5190 after YY_SYMBOL_PRINT where needed.

5244 Problem reported by Ralf Menzel.
5246 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
5248 * tests/actions.at: Test that stack overflow invokes destructors.
5249 From Marcus Holland-Moritz.
5250 * data/yacc.c (yyerrlab): Move the code that destroys the stack
5252 (yyreturn): to here. That way, destructors are called properly
5253 even if the stack overflows, or the user calls YYACCEPT or
5254 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
5255 (yyoverflowlab): Destroy the lookahead.
5257 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
5259 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
5261 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
5263 * NEWS: Bison-generated C parsers no longer quote literal strings
5264 associated with tokens.
5265 * src/output.c (prepare_symbols): Don't escape strings,
5266 since users don't want to see C escapes.
5267 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
5269 * tests/input.at (Torturing the Scanner): Likewise.
5270 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
5272 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
5274 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
5275 the data size is known to be too small and we can't increase it.
5276 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
5278 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
5280 * src/parse-gram.y: Include quotearg.h.
5281 (string_as_id): Quote $1 before using it as a key, since the
5282 lexer no longer quotes it for us.
5283 (string_content): Don't strip quotes, since lexer no longer
5285 * src/scan-gram.l: Include quotearg.h.
5287 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
5288 a key, since the rest of the lexer doesn't quote it.
5289 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
5290 * tests/regression.at (Token definitions): Check for backslashes
5293 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
5294 (YYSIZE_T): Define to unsigned long int when using an older compiler.
5295 (yyparse): Revamp code to generate long syntax error message, to
5296 make it easier to translate, and to avoid problems with arithmetic
5297 overflow. Change "virtual memory" to "memory" in diagnostic, since
5298 we don't know whether the memory is virtual.
5300 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
5302 * NEWS: Bison-generated C parsers now use the _ macro to
5304 * data/yacc.c (_) [!defined _]: New macro.
5305 All English strings wrapped inside this macro.
5306 * doc/bison.texinfo (Bison Parser): Document _.
5307 * po/POTFILES.in: Include src/parse-gram.c, since it now
5308 includes translateable strings that parse-gram.y doesn't.
5310 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
5312 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
5313 reverting the 2004-10-11 change to this function.
5314 (symbol_check_alias_consistency): Don't call symbol_type_set
5315 if the type name is already correct.
5316 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
5318 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
5320 * tests/regression.at (Token definitions): Don't use a token named
5321 c, as that generates a "#define c ..." that runs afoul of buggy
5322 stdlib.h that uses the identifier c as a member of struct
5323 drand48_data. Problem reported by Horst Wente.
5325 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
5327 * bootstrap: Change translation URL from
5328 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
5329 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
5330 redirection glitches. Problem reported by twlevo@xs4all.nl.
5332 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
5334 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
5335 after operands; POSIX says this isn't portable for the c99 command.
5337 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
5339 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
5340 immediately if a data overrun has occurred; this may help us track
5341 down what may be a spurious failure on MacOS.
5343 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
5345 Respond to problems reported by twlevo@xs4all.nl.

5355 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
5357 * src/tables.c (state_number_to_vector_number): Put it inside an
5358 "#if 0", since it's not currently used. Problem reported by
5361 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
5363 * src/output.c (escaped_output): Renamed from
5364 escaped_file_name_output, since we now use it for symbol tags as
5365 well. All uses changed.
5366 (symbol_destructors_output, symbol_printers_output):
5367 Escape symbol tags too.
5368 Problem reported by Matyas Forstner in
5369 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
5371 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
5373 * src/output.c (user_actions_output, token_definitions_output,
5374 symbol_destructors_output, symbol_printers_output): Likewise.
5375 * src/reader.c (prologue_augment): Likewise.
5376 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
5378 * src/vcg.c (output_edge): Don't quote linestyle arg.
5379 Problem reported by twlevo@xs4all.nl.
5381 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
5383 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
5384 example, reported by Derek M Jones. Also, make the example even
5385 more outrageous, to better illustrate how bad the problem is.
5387 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
5389 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
5390 putsym. Typo reported by Sebastian Piping.
5392 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5394 * doc/bison.texinfo (Language and Grammar): some -> same
5395 (Epilogue): int he -> in the
5396 Typos reported by Sebastian Piping via Justin Pence.
5398 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
5400 * tests/glr-regression.at (Improper handling of embedded actions
5401 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
5402 embedded actions and $-N in GLR parsers", work around an Autoconf bug
5403 with dollar signs in test names.
5404 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
5405 for a similar reason.
5407 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
5409 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
5410 wants to redefine G_VIEW.
5412 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
5414 * src/vcg.c (get_view_str): Remove case for normal_view.

5420 Problem reported by twlevo@xs4all.nl.
5422 * doc/bison.texinfo: Change @dircategory from "GNU programming
5423 tools" to "Software development". Requested by Richard Stallman
5426 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
5428 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
5429 Problem reported by twlevo@xs4all.nl.
5431 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
5433 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
5434 keyword; it's not needed with modern compilers, and it doesn't
5435 affect correctness with older compilers. Suggested by
5438 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
5440 * data/glr.c (yyuserAction): Add "default: break;" case to pacify

5448 already. Let config.h define any nonstandard values.
5450 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
5452 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
5453 for the benefit of slower hosts. Problem reported by
5456 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
5458 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
5459 being defined and not used.
5460 * data/lalr1.cc (yyparse): Likewise.
5461 Use "if (false)" rather than "if (0)".
5463 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
5465 * TODO: Mention that we should allow NUL bytes in tokens.
5467 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
5469 * src/scan-skel.l (<<EOF>>): Don't close standard output.
5470 Problem reported by Hans Aberg.
5472 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
5474 * src/getargs.c (version): Happy new year; update overall
5475 program copyright date from 2004 to 2005.
5477 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
5478 Problem reported by Hans Aberg.
5479 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
5480 (Output file names.): Add a test for the case when standard output
5483 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
5485 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
5486 to fix an oversight in the Bison 2.0 manual.
5488 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
5490 * NEWS: Version 2.0. Reformat the existing news items since
5491 1.875, so that related items are grouped together.
5492 * configure.ac (AC_INIT): Bump version to 2.0.
5493 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
5495 * tests/torture.at (Exploding the Stack Size with Alloca): Set
5496 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
5497 otherwise, we're not testing alloca. Unfortunately there's no
5498 simple way to consult HAVE_ALLOCA here.
5500 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
5503 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
5504 hand. This avoids a warning about comparing int to size_t when
5505 GCC warnings are enabled.
5507 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
5509 * NEWS: Bison-generated parsers no longer default to using the
5510 alloca function (when available) to extend the parser stack, due
5511 to widespread problems in unchecked stack-overflow detection.
5512 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
5513 responsibility to set it to a positive value. This lets the user
5514 specify a value that is not a preprocessor constant.
5515 * data/yacc.c (YYMAXDEPTH): Likewise.
5516 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
5517 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
5518 to be a compile-time constant. However, explain the constraints on it.
5519 Also, explain the constraints on YYINITDEPTH.
5520 (Table of Symbols): Explain that alloca is no longer the default.
5521 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
5524 * doc/bison.texinfo (Location Default Action): Mention that n must
5525 be zero when k is zero. Suggested by Frank Heckenbach.
5527 2004-12-22 Akim Demaille <akim@epita.fr>
5529 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
5530 (parser::state_type, parser::semantic_type, parser::location_type):
5531 Private, not public.
5532 (parser::parse): Return ints, not bool.
5533 Returning a bool introduces a problem: 0 corresponds to false, and
5534 it seems weird to return false on success. Returning true changes
5535 the conventions for yyparse.
5536 Alternatively we could return void and send an exception.
5537 There is no clear consensus (yet?).
5538 (state_stack, semantic_stack, location_stack): Rename as...
5539 (state_stack_type, semantic_stack_type, location_stack_type): these.
5540 Private, not public.

5542 * tests/testsuite.at, tests/Makefile.am: Adjust.
5544 2004-12-21 Akim Demaille <akim@epita.fr>

5548 2004-12-21 Akim Demaille <akim@epita.fr>
5550 Don't impose std::string for filenames.
5552 * data/lalr1.cc (b4_filename_type): New.
5553 (position::filename): Use it.
5554 (parser.hh): Move the inclusion of stack.hh and location.hh below
5555 the user code, so that needed headers for the filename type can be
5557 Forward declare them before the user code.
5558 * tests/Makefile.am (check-local, installcheck-local): Pass
5559 TESTSUITEFLAGS to the TESTSUITE.
5561 2004-12-20 Akim Demaille <akim@epita.fr>
5563 Use more STL like names: my_class instead of MyClass.
5565 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
5566 (SemanticStack, SemanticType, StateStack, StateType)
5567 (TokenNumberType, Stack, Slice, Traits, Parser::location)
5568 (Parser::value): Rename as...
5569 (location_stack, location_type, rhs_number_type, semantic_stack)
5570 (semantic_type, state_stack, state_type, token_number_type, stack)
5571 (slice, traits, parser::yylloc, parser::yylval): these.
5573 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
5575 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
5577 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
5578 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
5580 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
5582 Remove uses of 'short int' and 'unsigned short int'. This raises
5583 some arbitrary limits. It uses more memory but nowadays that's
5584 not much of an issue.
5586 This change does not affect the generated parsers; that's a different
5587 task, as some users will want to conserve memory there.
5589 Ideally we should use size_t to represent all object counts, and
5590 something like ptrdiff_t to represent signed differences of object
5591 counts; but that will require more code-cleanup than I have the
5592 time to do right now.
5594 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
5595 Use size_t, not int or short int, to count objects.
5596 * src/closure.c (nritemset, closure): Likewise.
5597 * src/closure.h (nritemset, closure): Likewise.

5611 * src/tables.c (vector_number, tally, action_number,

5613 * src/output.c (muscle_insert_short_int_table): Remove.
5615 2004-12-17 Akim Demaille <akim@epita.fr>
5617 * data/lalr1.cc: Extensive Doxygenation.
5618 (error_): Rename as...
5619 (error): this, since it is visible to the user.
5621 (Parser::message): Now an automatic variable from...
5622 (Parser::yyreport_syntax_error_): here.
5623 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
5625 * tests/input.at: Escape $.
5627 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
5629 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
5630 Parenthesize rhs to avoid obscure problems with mistakes like
5631 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
5632 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
5633 b4_rhs_location): Likewise.

5635 b4_rhs_location): Likewise.
5637 2004-12-16 Akim Demaille <akim@epita.fr>
5639 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
5640 yacc.c: be sure to stay within yycheck_.
5641 * tests/actions.at: Re-enable C++ tests.
5643 2004-12-16 Akim Demaille <akim@epita.fr>
5645 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
5648 2004-12-16 Akim Demaille <akim@epita.fr>
5650 Use #define to handle the %name-prefix.
5652 * data/glr.c, data/yacc.c: Comment changes.
5653 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
5654 so that one can refer to yylex in the parser file, and have it
5655 renamed, as is the case with other skeletons.
5657 2004-12-16 Akim Demaille <akim@epita.fr>

5679 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
5681 Fix some problems reported by twlevo at xs4all.
5682 * src/symtab.c (symbol_new): Report an error if the input grammar
5683 contains too many symbols. This is better than calling abort() later.
5684 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
5685 (struct node, struct graph):
5686 Rename member expand to stretch. All uses changed.
5687 (struct graph): Remove member layoutalgorithm. All uses removed.

5696 Add more Doxygen comments.
5697 (symprint_, stack_print_, reduce_print_, destruct_, pop)

5702 2004-12-15 Akim Demaille <akim@epita.fr>
5704 * data/lalr1.cc (lex_): Rename as...
5706 Move the trace here.
5707 Take the %name-prefix into account.
5708 Reported by Alexandre Duret-Lutz.
5710 2004-12-15 Akim Demaille <akim@epita.fr>
5712 Simplify the C++ parser constructor.
5714 * data/lalr1.cc (debug_): Rename as...
5715 (yydebug_): so that the parser's internals are always in the yy*
5718 (b4_parse_param_decl): Remove the leading comma as it is now only
5719 called as unique argument list.
5720 (Parser::Parser): Remove the constructor accepting a location and
5721 an initial debugging level.
5722 Remove from the other ctor the argument for the debugging level.
5723 (debug_level_type, debug_level, set_debug_level): New.
5725 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
5728 2004-12-15 Akim Demaille <akim@epita.fr>
5730 Remove b4_root related material: failure experiment
5731 (which goal was to allow to derive from a class).
5733 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
5734 definitions and uses.
5736 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
5738 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
5739 not 2, since it's not portable to subtract 1 from the start of an
5740 array. The new item 0 is never set or used. All uses changed.
5742 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
5743 the default definition of YYLLOC_DEFAULT. Problem reported
5744 by Frank Heckenbach.
5746 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
5748 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
5749 the normal case and one for the error case. Just use the
5750 first one uniformly. Problem reported by Frank Heckenbach.
5751 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
5752 use exactly the same macro in both places.
5753 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
5754 so that the normal-case YYRHSLOC works for the error case too.
5756 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
5757 (YYLLOC_DEFAULT): Use the same macro as glr.c.
5758 * doc/bison.texinfo (Location Default Action): Don't claim that
5759 we have an array of locations. Use the same macro for both glr
5760 and lalr parsers. Mention YYRHSLOC. Mention what happens when

5772 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
5774 * src/scan-skel.l: Include "complain.h", for "fatal".
5776 * src/relation.h (relation_print, relation_digraph):
5777 Relation sizes are of type relation_node, not size_t (this is
5778 merely a doc fix, since the two types are equivalent).
5779 (relation_transpose): Relation sizes are of type relation_node,
5781 * src/relation.c: Likewise.
5782 (top, infinity): Now of type relation_node, not int.
5783 (traverse, relation_transpose): Use relation_node, not int.
5785 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
5786 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
5787 (yyparse): Remove unused local introduced in 2004-10-25 patch.
5789 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
5790 specifying whether the test should be skipped. Use it tp
5791 specify that the [%defines %skeleton "lalr1.cc"] tests currently
5792 fail on some hosts, and should be skipped.
5794 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
5796 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
5797 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
5798 unless otherwise specified below.
5800 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
5801 to allocate kernel_base, kernel_items, kernel_size, since
5802 they needn't be initialized to 0.
5803 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
5804 * src/closure.c (new_closure): Likewise, for itemset.

5820 (goto_actions): Likewise for state_count.
5821 (pack_table): Likewise for base, pos, check.
5822 (tables_generate): Likewise for width.
5824 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
5825 for initial core. Just have a separate core, so we needn't worry
5826 about whether kernel_size and kernel_base are initialized.
5828 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
5829 kernel_size, kernel_items): Remove unnecessary initialization.

5835 conflrow, conflict_table, conflict_list, table, check):
5838 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
5839 This is because all callers pass unsigned int.
5840 * src/closure.h (new_closure): Likewise.
5842 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
5843 (build_relations): Initialize includes[i] in all cases.
5844 * src/reader.c (packgram): Always initialize rules[ruleno].prec
5845 and rules[ruleno].precsym. Initialize members in order.

5848 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
5850 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
5851 conflict_list[0] was always 0, but now it isn't initialized.
5853 * src/table.c (table_grow): When conflict_table grew, the grown
5854 area wasn't cleared. Fix this.
5856 * lib/.cvsignore: Add strdup.c, strdup.h.
5857 * m4/.cvsignore: Add strdup.m4.
5859 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
5861 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
5862 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
5863 GOTO_NUMBER_MAXIMUM, since we occasionally compute
5864 ngotos + 1 without checking for overflow.
5865 (build_relations): Use END_NODE, not -1, to denote end of edges.
5866 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
5867 build_relations): Use goto_number, not int, for goto numbers.

5872 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
5873 of #defining from yystype.
5874 Don't typedef yystype, C++ does not need it.
5875 This lets it possible to forward declare it as union.
5877 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
5879 * bootstrap (gnulib_modules): Add extensions.
5880 Problem reported by Jim Meyering.

5925 (yyrecoverSyntaxError): Use it when shifting the error token to
5926 have an accurate range, equivalent to the one computed by both
5927 yacc.c and lalr1.cc.
5928 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
5929 that column numbers start at column 0, as per GNU Coding
5930 Standards, the others tests, and the doc.
5931 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
5932 Adjust to the above change (first column is 0).
5933 And adjust the location of the "<error>", now covering the whole

5937 and Paul Eggert <eggert@cs.ucla.edu>
5939 Remove some arbitrary limits on goto numbers and relations.
5940 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
5941 initial values, since they're never used.
5942 (set_goto_map): ngotos is now unsigned, so test for overflow
5943 by seeing whether it wraps around to zero.
5944 * src/lalr.h (goto_number): Now size_t, not short int.
5945 (GOTO_NUMBER_MAXIMUM): Remove.
5946 * src/relation.c (relation_print, traverse, relation_transpose):
5947 Check for END_NODE rather than looking at sign.
5948 * src/relation.h (END_NODE): New macro.
5949 (relation_node): Now size_t, not short int.
5951 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
5953 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
5954 keyword, not an identifier. Problem reported by Baron Schwartz in
5955 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
5957 2004-10-11 Akim Demaille <akim@epita.fr>
5959 * src/symtab.c (symbol_check_alias_consistency): Also check
5960 type names, destructors, and printers.
5961 Reported by Alexandre Duret-Lutz.
5962 Recode the handling of associativity and precedence in terms
5963 of symbol_precedence_set.
5964 Accept no redeclaration at all, not even equal to the previous
5966 (redeclaration): New.
5967 Use it to factor redeclaration complaints.
5968 (symbol_make_alias): Don't set the type of the alias, let
5969 symbol_check_alias_consistency do it as for other features.
5970 * src/symtab.h (symbol): Add new member prec_location, and
5972 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
5973 * tests/input.at (Incompatible Aliases): New.
5975 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
5977 .cvsignore fixes to accommodate gnulib changes,
5978 and the practice of naming build directories "_build".
5979 * .cvsignore: Add "_*". Sort.
5980 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
5981 * m4/.cvsignore: Add "*_gl.m4".
5983 2004-10-06 Akim Demaille <akim@epita.fr>
5985 * src/parse-gram.y (add_param): Fix the truncation of trailing
5988 2004-10-05 Akim Demaille <akim@epita.fr>
5990 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
5991 whether the reducion was empty or not. This leaves room to
5992 improve the use of YYLLOC_DEFAULT in such a case.
5993 lalr1.cc is still experimental, so changing this is acceptable.
5994 And finally, there are probably not many users who changed the
5995 handling of locations in GLR, so changing is admissible too.
5997 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
5998 empty reduction, set @$ to an empty location ending the previously
6000 Adjust uses to make sure the code is triggered on empty
6002 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
6003 expected output: empty reductions have empty locations.
6005 2004-09-29 Akim Demaille <akim@epita.fr>
6007 * data/lalr1.cc: Move towards a more standard C++ coding style
6008 for templates: Class < T > -> Class<T>.
6010 2004-09-29 Akim Demaille <akim@epita.fr>
6012 * data/lalr1.cc: Reinstall the former ctor, for sake of
6013 compatibility, but warn it will be removed.
6014 Move towards a more standard C++ coding style (i.e., type *var ->
6017 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
6019 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
6020 since it's less likely to work if NULs are involved in the future.
6022 2004-09-27 Akim Demaille <akim@epita.fr>
6024 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
6026 2004-09-27 Akim Demaille <akim@epita.fr>
6028 * data/lalr1.cc (b4_parse_param_decl_1): New.
6029 (b4_parse_param_decl): Use it to have different names between attribute
6031 (b4_cc_constructor_call): Likewise.
6033 2004-09-24 Akim Demaille <akim@epita.fr>
6035 * src/parse-gram.y (add_param): Strip the leading and trailing
6036 blanks from a formal argument declaration.
6037 (YY_LOCATION_PRINT): New.
6039 2004-09-24 Akim Demaille <akim@epita.fr>
6041 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
6044 2004-09-24 Akim Demaille <akim@epita.fr>
6046 * doc/bison.texinfo (Table of Symbols): Sort.
6048 2004-09-21 Akim Demaille <akim@epita.fr>
6050 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
6051 the useless parentheses.
6052 Suggested by Paul Eggert.
6054 2004-09-20 Akim Demaille <akim@epita.fr>
6056 Let the initial-action act on the look-ahead, and use it for the
6057 "initial push" (corresponding to an hypothetical beginning-of-file).
6058 And let lalr1.cc honor %initial-action.
6060 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
6062 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
6063 (Parser::Parser): Remove the ctor that used to initialize it.
6064 (Parser::parse): Like in the other skeletons, issue the "starting
6065 parse" message before any action.
6066 Honor %initial-action.
6067 Initialize the stacks with the lookahead.
6068 * data/yacc.c: Let $$ and @$ in %initial-action designate the
6070 Push them in the stacks.
6071 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
6073 2004-09-20 Akim Demaille <akim@epita.fr>
6075 * doc/bison.texinfo (Initial Action Decl): New.
6077 2004-09-20 Akim Demaille <akim@epita.fr>
6079 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
6080 clearer criterion to define it.
6081 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
6082 When reducing on an empty RHS, use the latest stacked location as
6084 yylloc is not always available.
6085 * data/glr.c: Likewise.
6086 Also, honor initial-actions.
6088 2004-09-20 Akim Demaille <akim@epita.fr>
6090 * data/yacc.c (YY_LOCATION_PRINT): New.
6091 Define when we know YYLTYPE's structure, i.e., when the default
6092 YYLLOC_DEFAULT is used.
6093 * data/c.m4 (b4_yysymprint_generate): Use it.
6094 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
6095 value of the result.
6096 (error_start_): Replace with...
6097 (error_range_): this location array.
6098 This allows to replace code relying on the implementation of
6099 locations by portable code.
6100 * data/yacc.c (yylerrsp): Replace with...
6101 (yyerror_range): this.
6102 Every time a token is popped, update yyerror_range[0], to have an
6103 accurate location for the error token.
6104 * data/glr.c (YY_LOCATION_PRINT): New.
6105 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
6106 deference a pointer.
6107 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
6108 report the location in %printers.
6110 * src/scan-skel.l: Instead of abort, report error messages to ease
6111 understanding skeleton scanning failures.
6113 2004-09-16 Akim Demaille <akim@epita.fr>
6115 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
6116 (iterator, const_iterator): these, to be more in the C++ spirit.
6117 Also, return reverse iterators so that when displaying the stack
6118 we display its bottom first.
6119 (Parser::stack_print_, Parser::reduce_print_): Match the messages
6121 We should probably use vector here though.
6123 2004-09-16 Akim Demaille <akim@epita.fr>
6125 Have more complete shift traces.
6127 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
6128 to report Shifts instead of ad hoc YYDPRINTF invocations,
6129 including for the error token.
6130 * data/lalr1.cc (symprint_): Output the location.
6131 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
6132 output the location within the %printer.
6133 Activate GLR tests, at least to make sure they compile properly.
6134 They still don't pass though.
6135 * tests/calc.at: Adjust expect verbose output, since now "Entering
6136 state..." is on a different line than the "Shifting" message.
6138 2004-09-08 Akim Demaille <akim@epita.fr>
6140 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
6141 Bison directive from the Bison file to the invocation of this
6142 macro, so that these directives are passed to
6143 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
6144 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
6145 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
6146 the extra Bison directives instead of the whole series.
6147 Change the grammar so that there are recoverable errors, and
6148 unrecoverable errors. Now we can have the parser give up before
6149 consuming the whole input. As a result we now can observe that
6150 the lookahead is freed when needed.
6151 Change the parser source to parse argv[1] instead of a hard coded
6153 Simplify yylex, and give a value and location to EOF.
6154 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
6155 passed directives already coded in the file.
6156 Add some tests to check the location of "error".
6157 For some tests, the C++ parser is correct, and not yacc.c.
6158 For other tests, they provide different, but unsatisfying, values,
6159 so keep the C++ value so that at least one parser is "correct"
6160 according to the test suite.
6161 (Actions after errors): Remove, this is subsumed by the
6162 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
6164 2004-09-06 Akim Demaille <akim@epita.fr>
6166 * data/lalr1.cc: Adjust the indentation of the labels.
6170 2004-09-06 Akim Demaille <akim@epita.fr>
6172 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
6173 argument, an informative message.
6174 Call YY_SYMBOL_PRINT.
6175 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
6176 * data/lalr1.cc (destruct_): Likewise.
6177 In addition, no longer depend on b4_yysymprint_generate and
6178 b4_yydestruct_generate to generate these functions, do it "by
6181 2004-09-03 Akim Demaille <akim@epita.fr>
6183 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
6184 invoked, yydestruct the lookahead.
6185 * tests/calc.at (Calculator $1): Update the expected lengths of
6186 traces: there is an added line for the discarded lookahead.
6187 * doc/bison.texinfo (Destructor Decl): Some rewording.
6188 Define "discarded" symbols.
6190 2004-09-02 Akim Demaille <akim@epita.fr>
6192 * data/lalr1.cc (translate_, destruct_): No reason to be static.
6194 2004-09-02 Akim Demaille <akim@epita.fr>
6196 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
6197 (YYDSYMPRINTF): Rename as...
6198 (YY_SYMBOL_PRINT): this.
6199 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
6201 Use it instead of direct symprint_ calls.
6202 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
6205 2004-09-02 Akim Demaille <akim@epita.fr>
6207 * data/lalr1.cc (b4_yysymprint_generate): New.
6208 (symprint_): New member function, defined when YYDEBUG.
6209 Use it consistently instead of token/nterm debugging output by
6211 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
6212 %printer calls to use cdebug_ when using lalr1.cc.
6214 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
6216 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
6217 with #ifdef YYDEBUG.
6219 2004-08-26 Akim Demaille <akim@epita.fr>
6221 * doc/bison.texinfo (Implementing Loops): Rename as...
6222 (Implementing Gotos/Loops): this.
6224 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
6226 Adjust to latest gnulib.
6227 * bootstrap (gnulib_modules): Add xalloc-die.
6228 Set LC_ALL=C so that file names sort consistently.
6229 Prefer the gnulib copies of gettext.m4, glibc21.m4,
6230 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
6231 uintmax_t.m4, ulonglong.m4.
6232 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
6233 po.m4 since we are now using _gl.m4 instead.
6235 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
6237 * src/scan-action.l: Remove. Scanning of semantic actions is
6238 handled in scan-gram.l.
6240 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
6242 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
6244 * src/location.h (struct): The file member is a uniqstr.
6245 (equal_boundaries): Use UNIQSTR_EQ for comparison.
6247 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
6249 Fix bug with non-%union parsers that have printers or destructors,
6250 which led to a Bison core dump. Reported by Peter Fales in
6251 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
6253 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
6254 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
6255 not to our own type.
6256 * src/output.c (symbol_destructors_output, symbol_printers_output):
6257 Don't assume %union.
6258 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
6259 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
6260 UNION-FLAG. All callers changed.
6261 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
6262 Use type char, not unsigned int, when declaring an array of char;
6263 this lets us remove a cast.
6264 (Printers and Destructors): Add non-%union test cases.
6266 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
6268 * doc/bison.texinfo: Minor editorial changes, mostly to the new
6269 GLR writeups. E.g., avoid frenchspacing and the future tense,
6270 change "lookahead" to "look-ahead", and change "wrt" to "with
6273 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
6275 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
6276 New sections, split off from the GLR Parsers section. Put the new
6277 Simple GLR Parser near the start of the GLR section, for clarity.
6278 Rewrite connective text.
6280 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
6282 * doc/bison.texinfo (Simple GLR Parsers): New section.
6284 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
6286 * NEWS, TODO, doc/bison.texinfo:
6287 Use "look-ahead" instead of "lookahead", to be consistent.
6288 * REFERENCES: Fix incorrect reference to DeRemer and Pennello,
6289 while we're fixing "look-ahead".
6290 * src/conflicts.c (shift_set): Renamed from shiftset.
6291 (look_ahead_set): Renamed from lookaheadset.
6292 * src/print.c: Likewise.
6293 * src/getargs.c (report_args): Add "look-ahead" as the new canonical
6294 name for "lookahead".
6295 (report_types, usage): Likewise.
6296 * src/getargs.h (report_look_ahead_tokens): Renamed from
6298 * src/lalr.c (compute_look_ahead_tokens): Renamed from

6306 * tests/torture.at (AT_DATA_LOOK_AHEAD_TOKENS_GRAMMAR): Renamed from
6307 AT_DATA_LOOKAHEADS_GRAMMAR.
6309 2004-06-03 Paul Eggert <eggert@cs.ucla.edu>
6311 * README: Update location of patched M4 distribution.
6313 2004-05-30 Albert Chin-A-Young <china@thewrittenword.com>
6315 Don't assume the C++ compiler takes the same arguments as the C compiler
6317 * configure.ac (O0CXXFLAGS): New var.
6318 * tests/atlocal.in (CXXFLAGS): Use it.
6320 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>
6322 Fix some "make check" problems with C++ reported by
6323 Albert Chin-A-Young for Tru64 C++ in this thread:
6324 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html
6326 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
6327 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
6328 Output to a .cc file for C++, not to a .c file.

6330 * tests/regression.at (AT_CHECK_DANCER): Likewise.
6331 * tests/local.at (AT_COMPILE_CXX): Default to OUTPUT.cc, not OUTPUT.c.
6333 2004-05-28 Albert Chin-A-Young <china@thewrittenword.com>
6335 * tests/calc.at, tests/actions.at: Workaround for SGI
6336 C++ compiler. (trivial change)
6338 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
6340 Spent a few hours checking out which prerequisite versions the
6341 current sources actually require. I went all the way back to
6342 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
6343 a seemingly endless set of combinations of versions more recent
6344 than that. The bottom line is that the current sources require
6345 fairly recent versions of the build tools, and it'll be some work
6347 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
6348 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
6349 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
6350 Add comments explaining why those particular versions are
6353 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
6354 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
6355 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
6357 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
6358 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
6360 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
6362 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
6363 0.11.5. Suggested by Bruno Haible.
6364 * bootstrap: Remove gettext version checking.
6366 * doc/bison.texinfo (Decl Summary): Also mention that %union
6367 can depend on prerequisite types. Problem reported by Tim
6370 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
6372 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
6373 * README-alpha: Don't tell people not to package this.
6375 * bootstrap: Don't assume $(...) works; use `...` instead.
6376 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
6379 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
6380 put into the -d output file, and mention what to do if YYSTYPE is
6383 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
6385 Undo change made earlier today: it caused autopoint to not bring
6386 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
6389 * bootstrap: Check that gettext version matches what's in
6390 configure.ac. Warn users to ignore robots.txt ERROR 404.
6391 * bootstrap: Undo today's earlier change (logged below).
6392 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
6394 The gettext version checking is causing more trouble than it's
6395 curing; remove it. Problem reported by Paul Hilfinger.
6397 * bootstrap: Issue a warning that one can expect a message
6398 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
6399 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
6401 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
6403 Ensure that the C++ compiler used for testing actually works on a
6404 simple test program; if not, skip the C++-related tests. Problem
6405 reported by Vin Shelton in:
6406 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
6408 * m4/cxx.m4: New file.
6409 * configure.ac (BISON_TEST_FOR_WORKING_CXX_COMPILER): Add.
6410 * tests/atlocal.in (BISON_CXX_WORKS): Add.
6411 * tests/local.at (AT_COMPILE_CXX): Use it.
6413 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
6415 * data/glr.c (yylloc): Output this macro even if locations are not
6416 being generated, as the GLR parser needs it even in that case.
6417 Problem reported by Troy A. Johnson
6418 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
6420 * configure.ac (AC_INIT): Update to 1.875e.
6422 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
6424 * NEWS: Version 1.875d.
6425 * configure.ac (AC_INIT): Likewise.
6426 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
6428 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
6429 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
6430 lalr1.cc runs afoul of the first, and the last two are no longer
6431 supported by GCC 3.4.0.
6432 * README: Mention GNU m4 1.4 or later; mention m4 patches.

6474 gets copied to the output file.
6476 2004-04-28 Paul Eggert <eggert@twinsun.com>
6478 Get files from the gnulib and po repositories, instead of relying
6479 on them being in our CVS. Upgrade to latest versions of gnulib
6482 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
6483 * bootstrap: Bootstrap from gnulib and po repositories.
6484 Much of this code was stolen from GNU diff and GNU tar's bootstrap.

6549 Remove, as these files are now generated automatically
6550 by bootstrap or automake.

6609 so that this include file can stand alone.
6610 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
6611 does this now. Include subpipe.h first after config.h, to
6612 test whether it can stand alone.
6614 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
6615 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
6618 * tests/synclines.at (%union synch line): Put a dummy member in
6619 the union, because empty unions aren't allowed in C. Caught
6622 2004-04-13 Jim Meyering <jim@meyering.net>
6624 * src/conflicts.c (conflicts_print): Correct format string typo:

6728 it can be called with `%skeleton "lalr1.cc"', and do that.
6730 2004-02-02 Paul Eggert <eggert@twinsun.com>
6732 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
6733 $(top_srcdir)/lib and ../lib. This fixes a bug reported

6755 * src/output.c (output_skeleton): Rename local var.
6756 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
6757 Bison tokens, as this runs afoul of the 2003-10-07 change that
6758 disallowed NUL bytes in character constants or string literals.
6760 * tests/local.at: Require Autoconf 2.59's Autotest.
6761 * tests/testsuite.at: Don't include local.at, since we now assume
6762 Autoconf 2.59 or later. Autoconf 2.59 had some problems with

6787 2003-10-05 Paul Eggert <eggert@twinsun.com>
6789 * NEWS: Don't document %no-default-prec, as it's still
6791 * doc/bison.texinfo: Document %no-default-prec only if
6792 the defaultprec flag is set. Normally it's not.
6794 2003-10-04 Paul Eggert <eggert@twinsun.com>
6796 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
6797 non-modifiable lvalue, instead of a modifiable one.
6798 * doc/bison.texinfo (Actions): Document that $$ can
6799 be assigned to. Do not claim that $$ and $N are
6800 array element references: user code should not rely on this.

6862 When reducing initial empty rules, Bison parser read an initial
6863 location that is not defined. This results in garbage, and that
6864 affects Bison's own parser. Therefore we need (i) to extend Bison
6865 to support a means to initialize this location, and (ii) to use
6866 this CVS Bison to fix CVS Bison's parser.
6868 * src/reader.h, reader.c (epilogue_augment): Remove, replace
6870 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
6871 * src/parse-gram.y: Adjust.
6872 (%initial-action): New.
6873 (%error-verbose): Since we require CVS Bison, there is no reason
6875 * src/scan-gram.l: Adjust.
6876 * src/Makefile.am (YACC): New, to make sure we use our own parser.
6877 * data/yacc.c (yyparse): Use b4_initial_action.
6879 2003-08-25 Akim Demaille <akim@epita.fr>
6881 * doc/bison.texinfo: Don't promote stdout for error messages.
6883 2003-08-25 Akim Demaille <akim@epita.fr>
6885 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.

6892 2003-08-25 Akim Demaille <akim@epita.fr>
6894 * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
6897 2003-08-25 Akim Demaille <akim@epita.fr>
6899 * data/lalr1.cc (Parser::reduce_print_): New.
6902 2003-08-25 Akim Demaille <akim@epita.fr>
6904 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
6905 error recovery loops. This patch is based on
6906 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
6907 Also, augment the similarity between lalr1.cc and yacc.c.
6908 Note: the locations of error recovery rules are not correct yet.
6910 * data/lalr1.cc: Comment changes to augment the similarity between
6911 lalr1.cc and yacc.c.
6912 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
6913 (yyerrlab1): Remove, but where it used to be (now the bottom part of
6914 yyerrlab), when hitting EOF, pop the whole stack here instead of
6915 merely falling thru the default error handling mechanism.
6916 (yyerrorlab): New label, with the old contents of YYERROR,
6917 plus the following change: pop the stack of rhs corresponding
6918 to the production that invoked YYERROR. That is how Yacc
6919 behaves (required by POSIX).
6920 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
6923 2003-08-25 Akim Demaille <akim@epita.fr>
6925 Tune local.at so that people can "autom4te -l autotest calc.at -o
6926 calc" for instance, to extract a sub test suite.
6928 * tests/testsuite.at: Move the initialization, Autotest version
6929 requirement, and AT_TESTED invocation into...
6930 * tests/local.at: here.
6931 * tests/testsuite.at: Include it for compatibility with Autoconf
6933 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
6936 2003-08-04 Paul Eggert <eggert@twinsun.com>
6938 Rework code slightly to avoid gcc -Wtraditional warnings.
6939 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
6940 The returned value is now stored in *YY0. All callers changed.
6941 * src/output.c (merge_output): Adjust to the above change.
6943 2003-07-26 Paul Eggert <eggert@twinsun.com>
6945 * data/glr.c (YYASSERT): New macro.
6946 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
6947 yyresolveStates, yyprocessOneStack):
6948 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
6949 Derived from a suggestion by Frank Heckenbach.
6951 2003-07-25 Paul Eggert <eggert@twinsun.com>
6953 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
6954 for portability to K&R C (after ansi2knr, presumably). See
6955 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
6956 by Frank Heckenbach, though I have omitted the structure-initialization
6957 part of his glr-knr.diff patch since I recall that the Portable
6958 C Compiler didn't require that change.
6960 Let the user specify how to allocate and free memory.
6961 Derived from a suggestion by Frank Heckenbach in
6962 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
6963 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
6964 All uses of free, malloc, realloc changed to use these macros,
6965 and unnecessary casts removed.
6966 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
6968 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
6970 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
6971 use s.empty() rather than s == "" to test for empty string; see
6972 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
6975 2003-06-25 Akim Demaille <akim@epita.fr>
6977 * config/depcomp, config/install-sh: Update from masters.
6979 2003-06-20 Paul Eggert <eggert@twinsun.com>

6982 and return properly parenthesized result.
6983 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
6984 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
6985 Remove unnecessary parentheses from uses.

6987 conventions for parentheses.
6989 2003-06-19 Paul Eggert <eggert@twinsun.com>
6991 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
6992 yyreportTree): Do not assume that size_t is the same width as int,
6993 when printing sizes. Print sizes using an unsigned format.
6994 Problem reported by Frank Heckenbach in
6995 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
6997 Port to Forte Developer 7 C compiler.
6998 * data/glr.c (struct YYLTYPE): If locations are not being used,
6999 declare a single dummy member, as empty structs do not conform
7001 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
7002 the Forte Developer 7 C compiler complains that end-of-loop
7003 code is not reached.
7005 2003-06-17 Paul Eggert <eggert@twinsun.com>
7007 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
7008 avoid warnings from picky compilers about redefinition of PARAMS.

7018 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
7019 Don't use 'index' in comments, as it's a builtin fn on some hosts.
7020 * lib/bitset_stats.c: Include gettext.h unconditionally, as
7021 per recent gettext manual's suggestion.
7022 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):

7047 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
7048 `How Can I Reset @code{yyparse}', since texinfo does not allow
7049 arbitrary @ in node names.
7051 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
7052 shouldn't be needed according to the gettext 0.12.1 documentation
7053 but which seem to be needed anyway: codeset.m4 glibc21.m4
7054 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
7055 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.

7076 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
7077 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
7078 the tests right now.
7079 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
7080 yyerror are declared before use; C99 requires this.
7082 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
7084 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
7086 (yyrecoverSyntaxError): Correct the logic for setting and testing
7088 Correct comment on handling EOF.
7089 Allow states with only a default reduction, rather than failing
7090 (I can't quite reconstruct why these were not allowed before).
7092 Fixes to avoid problem that $-N rules in GLR parsers can cause
7093 buffer overruns, corrupting state.
7095 * src/output.c (prepare_rules): Output max_left_semantic_context
7097 * src/reader.h (max_left_semantic_context): New variable declaration.
7098 * src/scan-gram.l (max_left_semantic_context): Define.

7102 (yyresolveAction): Ditto.
7104 Fixes to problems with location handling in GLR parsers reported by
7105 Frank Heckenbach (2003/06/05).
7107 * data/glr.c (YYLTYPE): Make trivial if locations not used.
7108 (YYRHSLOC): Add parentheses, and define only if locations used.

7112 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
7114 * tests/cxx-type.at: Exercise location information; update tests
7115 to differentiate output with and without locations.
7116 Remove forward declarations of yylex and yyerror---caused errors
7117 because default YYLTYPE not yet defined.
7118 Change semantic actions to compute strings, rather than printing
7119 them directly (to test proper passing of semantics values). Change
7120 output to prefix notation and update test data and expected results.
7121 (yylex): Track locations.
7122 (stmtMerge): Return value rather than printing, and include arguments
7125 2003-06-03 Paul Eggert <eggert@twinsun.com>
7127 Avoid warnings generated by GCC 2.95.4 when Bison is
7128 configured with --enable-gcc-warnings.

7133 yy::Slice::operator[] (unsigned),
7134 yy::Slice::operator[] (unsigned) const):
7135 Rename local vars to avoid warnings.
7136 * tests/glr-regression.at (Improper handling of embedded actions
7137 and $-N in GLR parsers): Remove unused local variable from yylex.
7138 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
7139 (void) as arg when not pure, since we now assume C89 when building
7140 Bison. Pacify GCC by using parameter.
7142 2003-06-02 Paul Eggert <eggert@twinsun.com>
7144 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
7145 yy::Location::lines, yy::Location::columns): Rename arguments
7146 to avoid shadowing; this removes a warning generated by GCC 3.3.
7148 2003-06-01 Paul Eggert <eggert@twinsun.com>
7150 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
7151 to g++, as GCC 3.3 complains if you do it.
7152 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
7153 everything that WARNING_CFLAGS has, except omit warnings
7154 not suitable for C++.
7155 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
7156 * tests/atlocal.in (CXXFLAGS): New var.
7157 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
7159 Fix a GLR parser bug I reported in February; see
7160 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
7161 The problem was that GLR parsers did not conform to the C standard,
7162 because actions like { $1 = $2 + $3; } expanded to expressions
7163 that invoked YYFILL in separate subexpressions, and YYFILL assigned
7164 to a local variable. The C standard says that expressions
7165 like (var = f ()) + (var = f ()) have undefined behavior.
7166 Another problem was that GCC sometimes issues warnings that
7167 yyfill and its parameters are unused.
7169 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
7171 (yyfill): New function.
7173 (yyuserAction): Change type of yynormal to bool, so that it matches
7174 the new yyfill signature. Mark it as possibly unused.
7177 Follow up on a bug I reported in February, where a Bison-generated
7178 parser can loop. Provide a test case and a fix for yacc.c. I
7179 don't have a fix for lalr1.cc or for glr.c, unfortunately.
7180 The original bug report is in:
7181 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
7183 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
7184 macro's size was becoming unwieldy.
7185 (yyerrlab): Do not discard an empty lookahead symbol, as this
7186 might destroy garbage.
7187 (yyerrorlab): New label, with the old contents of YYERROR,
7188 plus the following change: pop the stack of rhs corresponding
7189 to the production that invoked YYERROR. That is how Yacc
7190 behaves, and POSIX requires this behavior.
7191 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
7192 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
7193 Define 'alarm' to do nothing if unistd.h is not available.
7194 Add a new rule "exp: '-' error;" to test the above change to
7195 data/yacc.c. Use 'alarm' to abort any test taking longer than
7196 10 seconds, as it's probably looping.
7197 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
7198 Also, the new yacc.c generates two fewer diagnostics for an
7201 2003-05-24 Paul Eggert <eggert@twinsun.com>
7203 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
7204 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
7205 This fixes a problem reported by John Bowman when the Compaq/HP
7206 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
7208 * data/yacc.c (union yyalloc): Likewise.
7209 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
7211 Switch from 'int' to 'bool' where that makes sense.

7296 hold parse-param arguments.
7297 * tests/calc.at: s/value/semantic_value/ because value clashes
7298 with a member of yy::b4_parser_class_name. Adjust C++ code
7299 to handle %parse-param. Enable %parse-param test in C++.
7301 2003-05-12 Paul Eggert <eggert@twinsun.com>
7303 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
7304 English a bit. Fix fclose typo. Change "const char" to "char
7305 const", and use ANSI C rather than K&R for "main". Suggest
7306 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
7307 and suggest yy_switch_to_buffer.
7309 2003-05-05 Paul Eggert <eggert@twinsun.com>
7311 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
7312 C89. This avoids a diagnostic on compilers that define __STDC__
7313 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
7314 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
7316 2003-05-03 Paul Eggert <eggert@twinsun.com>
7318 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
7319 Do not overrun array bounds.
7320 This should fix a bug reported today by Olatunji Oluwabukunmi in
7321 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
7323 2003-04-29 Akim Demaille <akim@epita.fr>
7325 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
7326 * src/getargs.c, src/getargs.h: here, as bool, not int.
7327 (nondeterministic_parser): New.
7328 * src/parse-gram.y, src/scan-gram.l: Support
7329 %nondeterministic-parser.
7330 * src/output.c (prepare): Use nondeterministic_parser instead
7331 of glr_parser where appropriate.
7332 * src/tables.c (conflict_row, action_row, save_row)
7333 (token_actions, token_actions, pack_vector): Ditto.
7335 2003-04-29 Akim Demaille <akim@epita.fr>
7337 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
7339 2003-04-29 Akim Demaille <akim@epita.fr>
7341 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
7342 with %pure-parser and %locations to exercise the patch from Yakov
7345 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
7347 * data/yacc.c: (b4_lex_param): Corrected for the case where
7348 %lex-param is provided and %pure-parser isn't.
7350 2003-04-27 Paul Eggert <eggert@twinsun.com>
7352 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
7353 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
7354 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
7355 if it is not defined.
7356 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
7358 2003-04-26 Paul Eggert <eggert@twinsun.com>
7360 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
7361 Declare to be of type suitable for the ninf value itself, not of
7362 type suitable for the corresponding table, since the latter might
7363 be unsigned but the ninf value might be negative. This fixes a
7364 bug reported by Alexandre Duret-Lutz in
7365 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
7367 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
7368 invokes it. We shouldn't invoke it twice because it will attempt
7369 to put error.o in the archive twice. This fixes a glitch reported
7370 by Martin Mokrejs in
7371 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
7373 2003-04-21 Paul Eggert <eggert@twinsun.com>
7375 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
7378 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
7380 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
7381 Fix obvious typo that results in uncompilable GLR parsers
7382 when both %pure-parser and %locations are used. (trivial change)
7384 2003-04-17 Paul Eggert <eggert@twinsun.com>
7386 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
7387 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
7388 Do not insert the expected token via unput, as this runs afoul
7389 of a POSIX-compatibility bug in flex 2.5.31.
7390 All uses changed to BEGIN the parent state,
7391 since we no longer insert the expected token via unput.
7392 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
7393 that is no longer emitted after the above change.
7395 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
7396 the first one. This change is from Paul Hilfinger, and it fixes
7397 regression reported by Werner Lemberg in
7398 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
7400 (resolve_sr_conflict): Don't invoke state_errs_set
7401 unless one or more tokens have been explicitly made errors.
7402 Otherwise, the above change causes Bison to abort.
7404 * tests/existing.at (GNU pic Grammar): New test case, taken from
7407 2003-03-31 Akim Demaille <akim@epita.fr>
7409 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
7411 2003-03-31 Akim Demaille <akim@epita.fr>
7413 * src/output.c (prepare_symbols): Avoid trailing spaces in the
7416 2003-03-31 Akim Demaille <akim@epita.fr>
7418 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
7419 From Paul Hilfinger.
7421 2003-03-29 Akim Demaille <akim@epita.fr>
7423 * m4/error.m4: Do not put under dynamic conditions some code which
7424 expansion is under static control.
7426 2003-03-29 Akim Demaille <akim@epita.fr>
7428 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
7430 2003-03-29 Akim Demaille <akim@epita.fr>
7432 * doc/bison.texinfo (Strings are Destroyed): New.
7434 2003-03-13 Paul Eggert <eggert@twinsun.com>
7436 * .cvsignore: Add configure.lineno.
7437 * src/.cvsignore: Add yacc.
7438 * tests/.cvsignore: Add testsuite.log.
7439 * doc/fdl.texi: Sync with latest FSF version.
7441 2003-03-12 Paul Eggert <eggert@twinsun.com>
7443 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
7444 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
7445 cursor, instead of leaving it undefined. This fixes a bug
7446 reported by Tim Van Holder in
7447 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
7448 * tests/input.at (Torturing the Scanner): Test the scanner on
7449 an empty input file, which was Tim Van Holder's test case.
7451 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
7452 <sys/resource.h> can be included, include sys/time.h and
7453 sys/times.h first, if available. This works around the SunOS
7454 4.1.4 porting bug reported by Bruce Becker in
7455 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
7457 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
7458 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
7461 Merge changes from gnulib. This was prompted because the CVS
7462 snapshot didn't build on Solaris 7 due to strnlen problems.
7464 These changes need to be merged back into gnulib:
7465 * lib/hash.c: Include <stdbool.h> unconditionally.
7466 * m4/onceonly.m4 (m4_quote): New macro.
7467 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
7468 Quote AC_FOREACH variable-expansions properly.
7469 The 2003-01-03 obstack.h change also needs merging.
7470 {end of changes requiring merging}
7472 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
7473 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
7474 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
7475 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
7476 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
7477 New files, imported from gnulib.
7478 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
7481 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
7482 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
7485 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
7487 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
7488 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
7489 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
7490 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
7491 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
7492 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
7493 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
7494 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
7495 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
7496 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
7497 (jm_PREREQ_ARGMATCH): Remove.
7498 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
7499 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
7501 * src/system.h: Include <stdbool.h> unconditionally.
7503 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
7504 assuming at least C89 in the bitset code for some time now.
7506 2003-03-03 Akim Demaille <akim@epita.fr>
7510 2003-03-02 Akim Demaille <akim@epita.fr>
7512 * doc/bison.texinfo (Table of Symbols): Reactivate the
7513 documentation for %lex-param, and %parse-param.
7515 2003-03-02 Akim Demaille <akim@epita.fr>
7517 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
7518 generate verbose error messages.
7519 Use the number of tokens as an upper bound in yytname, as it
7520 cannot be a non terminal.
7522 2003-03-02 Akim Demaille <akim@epita.fr>
7524 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
7527 2003-03-02 Akim Demaille <akim@epita.fr>
7529 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
7530 Use them to exercise yycheck overrun.
7531 Based on Andrew Suffield's grammar.
7533 2003-03-02 Akim Demaille <akim@epita.fr>
7535 Create tests/local.at for Bison generic testing macros.
7537 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
7538 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
7540 * tests/calc.at (AT_CHECK_CALC): Adjust.
7541 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
7542 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
7543 * tests/local.at: here.
7544 (AT_COMPILE_CXX): Tags the tests using it as c++.
7545 Ignore the test if CXX is not functional.
7547 2003-03-01 Paul Eggert <eggert@twinsun.com>
7549 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
7550 not loc->end, since loc->end might contain garbage and this leads
7551 to undefined behavior on some platforms.
7552 (id_loc, token_start): Use (IF_LINTed) initial values that do not
7553 depend on *loc, so that the reader doesn't give the the false
7554 impression that *loc is initialized.
7555 (<INITIAL>"%%"): Do not bother setting code_start, since its value
7556 does not survive the return.
7558 2003-03-01 Akim Demaille <akim@epita.fr>
7560 * src/scan-gram.l (code_start): Always initialize it when entering
7561 into yylex, as SC_EPILOGUE is activated *before* the corresponding
7562 yylex invocation. An alternative would be making it static, but
7563 then it starts with the second %%'s beginning, instead of its end.
7565 2003-02-28 Paul Eggert <eggert@twinsun.com>
7567 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
7568 around a UnixWare 7.1.1 porting bug reported by John Hughes in
7569 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
7571 2003-02-26 Paul Eggert <eggert@twinsun.com>
7573 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
7574 Remove Sequent/Pyramid discussion (nobody uses them any more).
7575 Merge VMS and MS-DOS discussion; these ports may well be dead
7576 but let's keep mentioning them for now. Put <> around email
7577 addresses. Add copyright notice.
7579 2003-02-24 Paul Eggert <eggert@twinsun.com>
7581 * data/glr.c (yy_reduce_print): yylineno -> yylno,
7582 to avoid collision with flex use of yylineno.
7583 Problem reported by Bruce Lilly in
7584 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.

7593 change integer types.
7594 Suggested by Paul Eggert.
7596 2003-02-21 Akim Demaille <akim@epita.fr>
7598 * doc/bison.texinfo: Use "location" consistently to refer to @n,
7599 to avoid confusions with lalr1.cc's notion of Position.
7600 Suggested by Paul Eggert.
7602 2003-02-20 Akim Demaille <akim@epita.fr>
7604 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
7605 before initial_columns.
7606 (location.hh): Use consistent variable names when defining the
7608 Use "last" so that we subtract from Positions, not from unsigned.
7610 2003-02-20 Akim Demaille <akim@epita.fr>
7612 * data/lalr1.cc (position.hh): New subfile, including the extended
7613 and Doxygen'ed documentation of class Position.
7614 (location.hh): Use it.
7615 Document a` la Doxygen.
7616 With the help of Benoit Perrot.
7618 2003-02-20 Akim Demaille <akim@epita.fr>
7620 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
7622 Redefine AT_YYERROR_SEES_LOC_IF using it.
7623 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
7625 Don't use the location in yy::Parser::error_ and
7626 yy::Parser::print_ when not %locations.
7627 Activate more lalr1.cc tests.
7629 2003-02-19 Akim Demaille <akim@epita.fr>
7631 * data/lalr1.cc: When displaying a line number, be sure to make it
7634 2003-02-19 Akim Demaille <akim@epita.fr>
7636 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
7638 (YYABORT, YYACCEPT, YYERROR): New.
7639 * tests/calc.at: Renable the lalr1.cc test.
7641 2003-02-19 Akim Demaille <akim@epita.fr>
7643 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
7644 error recovery, mixing with/without pops and discarding of the
7647 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
7649 2003-02-17 Paul Eggert <eggert@twinsun.com>
7651 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
7652 * tests/testsuite.at (AT_COMPILE): Use them.
7653 This fixes the testsuite problem reported by Robert Lentz in
7654 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
7656 2003-02-12 Paul Eggert <eggert@twinsun.com>
7658 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
7659 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
7660 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
7661 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
7662 Check for malloc failure, for consistency with yacc.c.
7663 (yytname_size): Remove, for consistency with yacc.c.
7665 The bug still remains in data/lalr1.cc, as I didn't have time
7668 2003-02-06 Akim Demaille <akim@epita.fr>
7670 * configure.ac (GXX): Rename as...
7671 (CXX): this, to keep the original Autoconf semantics.

7685 * tests/testsuite.at (AT_COMPILE_CXX): New.
7686 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
7687 locations in a more synthetic way.
7688 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
7690 Adjust the C locations to match those from Emacs: first column is
7692 Change all the expected results.
7693 Conform to the GCS: simplify the locations when applicable.
7694 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
7695 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
7696 these CPP macros with the m4 macros new defined by...

7701 (AT_CHECK_POPDEFS): Undefine them.
7702 (AT_CHECK_CALC_LALR1_CC): New.
7703 Use it for the first lalr1.cc test.
7705 2003-02-04 Akim Demaille <akim@epita.fr>

7708 Location as is defined.
7710 2003-02-04 Akim Demaille <akim@epita.fr>

7765 param to have same name as that of enum, so that we don't use
7766 "s" to stand for a non-state.
7768 2003-02-02 Akim Demaille <akim@epita.fr>
7770 * src/scan-skel.l: Scan more than one inert character per yylex
7773 2003-02-01 Paul Eggert <eggert@twinsun.com>
7777 * po/LINGUAS: Add ms.
7779 2003-01-30 Akim Demaille <akim@epita.fr>
7781 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
7783 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
7785 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
7788 Changes in response to error report by S. Eken: GLR mode does not
7789 handle negative $ indices or $ indices in embedded rules correctly.
7790 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
7792 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
7793 (b4_rhs_location): Ditto.
7794 (yyfill): New function to copy from stack tree into array
7796 (yyuserAction): Modify to allow incremental move of semantic values
7797 to rhs array when in GLR mode.
7798 Define YYFILL to use in user-defined actions to fill semantic array
7800 Remove dummy use of yystack, as there is now a guaranteed use.
7801 (yydoAction): Modify to allow incremental move of semantic values
7802 to rhs array when in GLR mode.
7803 (yyresolveAction): Ditto.
7804 (yyglrShiftDefer): Update comment.
7805 (yyresolveStates): Use X == NULL for pointers, not !X.
7806 (yyglrReduce): Ditto.
7809 * tests/glr-regr1.at: Rename to ...
7810 * tests/glr-regression.at: Add new regression test for the problems
7811 described above (adapted from S. Eken).
7812 Update copyright notice.
7813 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
7814 * tests/Makefile.am: Ditto.
7816 2003-01-28 Paul Eggert <eggert@twinsun.com>
7818 * data/lalr1.cc: Do not use @output_header_name@ unless
7819 b4_defines_flag is set. This fixes two bugs reported by
7821 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
7822 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
7824 2003-01-21 Paul Eggert <eggert@twinsun.com>
7826 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
7827 we don't need to worry about yyerrlab1 being reported as an
7828 "unused label" by non-GCC C compilers. The downside is that if
7829 locations are used then a couple of statements are duplicated each
7830 time YYERROR is invoked, but the upside is that the warnings
7832 (yyerrlab1): Move code to YERROR.
7833 (yyerrlab2): Remove. Change uses back to yyerrlab1.
7834 This reverts some of the 2002-12-27 change.
7836 2003-01-17 Paul Eggert <eggert@twinsun.com>
7838 * src/output.c (symbol_printers_output): Fix typo that led
7839 to core dump. Problem reported by Antonio Rus in
7840 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
7842 2003-01-13 Akim Demaille <akim@epita.fr>,
7843 Quoc Peyrot <chojin@lrde.epita.fr>,
7844 Robert Anisko <anisko_r@lrde.epita.fr>
7846 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
7847 when the stacks contain one element, as the loop would otherwise
7848 free the last state, and then use the top state (the one we just
7849 popped). This means that the initial elements will not be freed
7850 explicitly, as is the case in yacc.c; it is not a problem, as
7851 these elements have fake values.
7853 2003-01-11 Paul Eggert <eggert@twinsun.com>
7855 * NEWS: %expect-violations are now just warnings, reverting
7856 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
7857 bootstrapping problem reported by Matthias Klose; see
7858 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
7859 * src/conflicts.c (conflicts_print): Likewise.
7860 * tests/conflicts.at (%expect not enough, %expect too much,
7861 %expect with reduce conflicts): Likewise.
7862 * doc/bison.texinfo (Expect Decl): Document this. Also mention
7863 that the warning is enabled if the number of conflicts changes
7864 (not necessarily increases).
7866 * src/getargs.c (version): Update copyright year.
7868 2003-01-09 Akim Demaille <akim@epita.fr>
7870 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
7872 2003-01-08 Paul Eggert <eggert@twinsun.com>
7874 * Makefile.maint (WGETFLAGS):
7875 New macro, containing "-C off" to disable proxy caches.
7876 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
7877 (rel-check): Use $(WGET) instead of wget.
7879 2003-01-06 Paul Eggert <eggert@twinsun.com>
7881 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
7882 the GLR paper of Scott, Johnstone and Hussain.
7884 2003-01-04 Paul Eggert <eggert@twinsun.com>
7886 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
7887 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
7888 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
7889 (EXTRA_LIBRARIES): New var, for liby.a.
7890 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
7891 (EXTRA_SCRIPTS): New var, for yacc.
7893 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
7894 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
7895 Problem reported by Nelson H. F. Beebe.
7897 2003-01-03 Paul Eggert <eggert@twinsun.com>
7899 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
7900 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
7901 when compiling Bison 1.875's `bitset bset = obstack_alloc
7902 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
7904 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
7905 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
7906 grow to a huge size with typical invocation.
7908 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
7909 Use the pattern recommended by Autoconf 2.57, except also protect
7910 against double-definition.
7911 * src/system.h: Likewise.
7912 Portability issues reported by Nelson H. F. Beebe.
7914 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
7915 All uses changed. Provide a definition in both C and C++.
7916 (yytrue, yyfalse): Define even if defined (__cplusplus).
7918 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
7919 Reported by Nelson H. F. Beebe.
7921 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
7923 2003-01-02 Paul Eggert <eggert@twinsun.com>
7925 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
7926 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
7927 Bug reported by Nelson H. F. Beebe.
7929 2003-01-01 Paul Eggert <eggert@twinsun.com>
7933 2002-12-30 Paul Eggert <eggert@twinsun.com>
7935 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
7937 (<INITIAL>","): Here. This causes stray "," to be treated
7940 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
7941 last brace in braced code when not in Yacc mode, for compatibility
7942 with Bison 1.35. This resurrects the 2001-12-15 patch to
7945 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
7946 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
7948 2002-12-28 Paul Eggert <eggert@twinsun.com>
7950 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
7951 that of SYM's type. This fixes Debian bug 168069, reported by
7954 2002-12-28 Paul Eggert <eggert@twinsun.com>
7958 Switch back to the Yacc style of conflict reports, undoing some
7959 of the 2002-07-30 change.
7960 * doc/bison.texinfo (Understanding): Use Yacc style for
7961 conflict reports. Also, use new way of locating rules.
7962 * src/conflicts.c (conflict_report):
7963 Renamed from conflict_report_yacc, removing the old
7964 'conflict_report'. Translate the entire conflict report at once,
7965 so that we don't assume that "," has the same interpretation in
7967 (conflicts_output): Use Yacc-style conflict report for each state,
7968 instead of our more-complicated style.
7969 (conflicts_print): Use Yacc-style conflict report, except print
7970 the input file name when not emulating Yacc.
7971 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
7972 Conflicted Reduction, %expect not enough, %expect too much,
7973 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
7974 * tests/existing.at (GNU Cim Grammar): Likewise.
7975 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
7977 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
7978 fatal): Don't invoke fflush; it's not needed and it might even be
7979 harmful for stdout, as stdout might not be open.
7980 * src/reduce.c (reduce_print): Likewise.
7982 2002-12-27 Paul Eggert <eggert@twinsun.com>
7984 Fix a bug where error locations were not being recorded correctly.
7985 This problem was originally reported by Paul Hilfinger in
7986 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
7988 * data/yacc.c (yyparse): New local var yylerrsp, to record the
7989 top of the location stack's error locations.
7990 (yyerrlab): Set it. When discarding a token, push its location
7991 onto yylerrsp so that we don't lose track of the error's end.
7992 (yyerrlab1): Now is only the target of YYERROR, so that we can
7993 properly record the location of the action that failed. For GCC
7994 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
7995 GCC warning about yyerrlab1 being unused if YYERROR is unused.
7996 (yyerrlab2): New label, which yyerrlab now falls through to.
7997 Compute the error's location by applying YYLLOC_DEFAULT to
7998 the locations of all the symbols that went into the error.
7999 * doc/bison.texinfo (Location Default Action): Mention that
8000 YYLLOC_DEFAULT is also invoked for syntax errors.
8001 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
8002 Error locations include the locations of all the tokens that were
8003 discarded, not just the last token.
8005 2002-12-26 Paul Eggert <eggert@twinsun.com>
8007 * src/files.c: Include quote.h.
8008 (compute_output_file_names): Warn if we detect conflicting
8009 outputs to the same file. This should catch the misunderstanding
8010 exemplified by Debian Bug 165349, reported by Bruce Stephens..
8012 * src/conflicts.c (conflicts_print): If the user specifies
8013 "%expect N", report an error if there are any reduce/reduce
8014 conflicts. This is what the manual says should happen.
8015 This fixes Debian bug 130890, reported by Anthony DeRobertis.
8016 * tests/conflicts.at (%expect with reduce conflicts): New test.
8018 Don't use m4_include on relative file names, as it doesn't work as
8019 desired if there happens to be a file with that name under ".".
8021 * m4sugar/version.m4: Remove; it was included but it wasn't used.
8022 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
8023 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
8024 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
8025 * src/output.c (output_skeleton): Use full path names when
8026 specifying a file to include; don't rely on include path, as
8027 it's unreliable when the working file contains a file with
8030 2002-12-25 Paul Eggert <eggert@twinsun.com>
8032 Remove obsolete references to bison.simple and bison.hairy.
8033 Problem mentioned by Aubin Mahe in
8034 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
8035 * data/glr.c: Comment fix.
8036 * doc/bison.1: Remove references. Also, mention "yacc".
8038 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
8041 * src/parse-gram.y (declaration): Use enum "report_states" rather
8042 than its numeric value 1.
8044 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
8045 opening a new one. This fixes Debian bug 165349, reported by
8048 2002-12-24 Paul Eggert <eggert@twinsun.com>
8052 * Makefile.maint (cvs-update): Don't assume that the shell
8053 supports $(...), as Solaris sh doesn't.
8055 * src/parse-gram.y (lloc_default): Remove test for empty
8056 nonterminals at the end, since it didn't change the result.
8058 2002-12-24 Paul Eggert <eggert@twinsun.com>
8060 If the user does not define YYSTYPE as a macro, Bison now declares it
8061 using typedef instead of defining it as a macro. POSIX requires this.
8062 For consistency, YYLTYPE is also declared instead of defined.
8064 %union directives can now have a tag before the `{', e.g., the
8065 directive `%union foo {...}' now generates the C code
8066 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
8067 The default union tag is `YYSTYPE', for compatibility with Solaris 9
8068 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
8069 instead of `yyltype'.
8071 `yystype' and `yyltype' are now obsolescent macros instead of being
8072 typedefs or tags; they are no longer documented and will be
8073 withdrawn in a future release.
8075 * data/glr.c (b4_location_type): Remove.
8076 (YYSTYPE): Renamed from yystype.
8077 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
8078 (struct YYLTYPE): Renamed from struct yyltype.
8079 (YYLTYPE): Renamed from yyltype.
8080 (yyltype, yystype): New (and obsolescent) macros,
8081 for backward compatibility.
8082 * data/yacc.c: Likewise.
8084 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
8085 does not specify a union tag. This is for compatibility with
8088 * src/parse-gram.y (add_param): 2nd arg is now char * not char
8089 const *, since it is now modified by stripping surrounding { }.
8090 (current_braced_code): Remove.
8091 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
8092 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
8093 trailing " {...}". Now of type <chars>.
8094 (grammar_declaration): Adjust to bundled tokens.
8095 (code_content): Remove; stripping is now done by add_param.
8096 (print_token_value): Print contents of bundled tokens.
8097 (token_name): New function.
8099 * src/reader.h (braced_code, current_braced_code): Remove.
8100 (token_name): New decl.
8102 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
8103 token_type, not braced_code code_kind. All uses changed.
8104 (SC_PRE_CODE): New state, for scanning after a keyword that
8105 has (or usually has) an immediately-following braced code.
8106 (token_type): New local var, to keep track of which token type
8107 to return when scanning braced code.
8108 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
8109 <INITIAL>"%parse-param", <INITIAL>"%printer",
8110 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
8111 instead of returning a token type immediately.
8112 (<INITIAL>"{"): Set token type.
8113 (<SC_BRACED_CODE>"}"): Use it.
8114 (handle_action_dollar, handle_action_at): Now returns bool
8115 indicating success. Fail if ! current_rule; this prevents a core dump.
8116 (handle_symbol_code_dollar, handle_symbol_code_at):
8117 Remove; merge body into caller.
8118 (handle_dollar, handle_at): Complain in invalid contexts.
8120 * NEWS, doc/bison.texinfo: Document the above.
8121 * NEWS: Fix years and program names in copyright notice.
8123 2002-12-17 Paul Eggert <eggert@twinsun.com>
8125 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
8126 Reporting, Table of Symbols): Omit mentions of %lex-param and
8127 %parse-param from the documentation for now.
8129 2002-12-15 Paul Eggert <eggert@twinsun.com>
8131 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
8132 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
8133 lookahead symbol, and which sets yychar in parser actions) and it
8134 disagreed with the Bison documentation. Bug
8135 reported by Andrew Walrond.
8137 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
8138 as the caller now does that.
8139 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
8140 (YYEMPTY): Parenthesize right hand side, since others use it.
8141 (yyparse): Don't assume that our generated code is the only code
8144 2002-12-13 Paul Eggert <eggert@twinsun.com>
8148 POSIX requires a "yacc" command.
8149 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
8150 (MOSTLYCLEANFILES): Add yacc.
8152 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
8153 as an alias for bison y.
8155 * po/LINGUAS: Add da.
8157 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
8158 problem with latest <getopt.h>.
8159 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
8161 * doc/fdl.texi: Upgrade to 1.2.
8162 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
8163 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
8164 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
8166 * config/install-sh: Sync with autotools.
8168 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
8169 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
8170 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
8171 locations are requested.
8172 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
8173 locations are requested.
8175 2002-12-12 Paul Eggert <eggert@twinsun.com>
8177 Remove unportable casts and storage allocation tricks.
8178 While we're at it, remove almost all casts, since they
8179 usually aren't needed and are a sign of trouble.
8181 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
8183 * src/derives.c (derives_compute): Do not subtract NTOKENS from
8184 the pointer DSET returned by malloc; this isn't portable.
8185 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
8186 Similarly for DERIVES.
8187 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
8188 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
8189 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
8191 * src/derives.c (derives_compute): Do not bother invoking
8192 int_of_rule_number, since rule numbers are integers.
8194 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
8195 rather than XMALLOC (char, N).
8197 * src/files.c (filename_split): Rewrite to avoid cast.
8199 * src/gram.h (symbol_number_as_item_number,
8200 item_number_as_symbol_number, rule_number_as_item_number,
8201 item_number_as_rule_number):
8202 Now inline functions rather than macros, to avoid casts.
8203 * src/state.h (state_number_as_int): Likewise.
8204 * src/tables.c (state_number_to_vector_number,
8205 symbol_number_to_vector_number): Likewise.
8207 * src/gram.h (int_of_rule_number): Remove; no longer used.
8209 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
8210 since the resulting storage is always stored into.
8212 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
8215 * src/muscle_tab.c (muscle_m4_output):
8216 Now inline. Return bool, not int.
8217 * src/state.c (state_compare): Likewise.
8218 * src/symtab.c (symbol_check_defined,
8219 symbol_check_alias_consistency, symbol_pack, symbol_translation,
8220 hash_compare_symbol, hash_symbol):
8222 * src/uniqstr.c (uniqstr_print): Likewise.
8223 * src/muscle_tab.c (muscle_m4_output_processor):
8224 New function, to avoid casts.
8225 * src/state.c (state_comparator, stage_hasher): Likewise.
8226 * src/symtab.c (symbol_check_defined_processor,
8227 symbol_check_alias_consistency_processor, symbol_pack_processor,
8228 symbol_translation_processor, hash_symbol_comparator,
8229 hash_symbol_hasher): Likewise.
8230 * src/uniqstr.c (uniqstr_print_processor): Likewise.
8231 * src/muscle_tab.c (muscles_m4_output):
8232 Use new functions instead of casting old functions unportably.
8233 * src/state.c (state_hash_new): Likewise.
8234 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
8235 symbols_token_translations_init):
8237 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
8239 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
8240 var instead of casting to long, to avoid casts.
8241 (prepare_states): Use MALLOC rather than alloca, so that we don't
8242 have to worry about alloca.
8243 * src/state.c (state_hash_lookup): Likewise.
8245 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
8246 local var instead of casting to unsigned char, to avoid casts.

8249 STATE_ALLOC): Remove.
8250 (transitions_new, errs_new, reductions_new, state_new): Use malloc

8253 (state_new): Initialize all members.
8255 * src/state.c (state_hash): Use unsigned accumulator, not signed.
8257 * src/symtab.c (symbol_free): Remove; unused.

8263 (symbol_processor): Remove.
8264 (symbols_do): Remove decl; now static.

8268 (<inttypes.>, <stdint.h>): Include if available.
8269 (uintptr_t): New type, if system lacks it.

8277 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
8278 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
8280 * src/vcg.h: Correct misspellings.
8282 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
8285 * src/getargs.c (getargs): Don't assume EOF == -1.
8287 2002-12-09 Paul Eggert <eggert@twinsun.com>
8289 Change identifier spellings to avoid collisions with names
8290 that are reserved by POSIX.
8292 Don't use names ending in _t, since POSIX reserves them.
8293 For consistency, remove _e and _s endings -- they're weren't
8294 needed to remove ambiguity. All uses changed.
8295 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
8296 turn was just renamed from struniq_t.
8297 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
8298 which in turn was just renamed from struniq_processor_t.

8370 value_t_as_yystype -> value_as_yystype.
8372 Don't include <errno.h> in the mainstream code, since it
8373 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
8374 * lib/get-errno.c, lib/get-errno.h: New files.
8375 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
8377 * src/files.c (xfopen, xfclose): Use get_errno instead of errno.

8384 * src/system.h: Do not include <errno.h>.
8385 (TAB_EXT): Renamed from EXT_TAB.
8386 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
8388 Avoid str[a-z]*, since <string.h> reserves that name space.
8389 Change all instances of "struniq" in names to "uniqstr", and
8390 likewise for "STRUNIQ" and "UNIQSTR".
8391 * src/uniqstr.c: Renamed from src/struniq.c.
8392 * src/uniqstr.h: Renamed from src/struniq.h.

8403 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.
8404 (N_EXPAND): Renamed from N_STRETCH.

8428 for consistency with other names.
8429 * lib/timevar.h (timevar_report): New decl.
8430 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
8433 Sort include-file uses.
8435 Reorder all include files under src to be in the order "system.h".
8436 then the ../lib include files in angle brackets (alphabetized),
8437 then the . include files in double-quotes (alphabetized). Fix
8438 dependency breakages encountered in this process, as follows:
8439 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
8440 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
8441 * src/state.h: Include "symtab.h".
8443 2002-12-08 Paul Eggert <eggert@twinsun.com>
8445 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
8446 since this causes problems when __file__ contains character
8447 sequences like "@" that are treated specially by src/scan-skel.l.
8448 Instead, just use the file's basename. This fixes the bug
8449 reported by Martin Mokrejs in
8450 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
8452 2002-12-06 Paul Eggert <eggert@twinsun.com>
8454 Add support for rules that do not have trailing semicolons, as
8455 POSIX requires. Improve the quality of locations in Bison
8458 * src/location.c: Include <quotearg.h>.
8459 (empty_location): Now const.
8460 (location_print): New function. Follow the recommendation of the
8461 GNU Coding Standards for locations that span file boundaries.
8462 * src/location.h: Do not include <quotearg.h>; no longer needed.
8463 (boundary): New type.
8464 (location_t): Use it. This allows locations to span file boundaries.
8465 All member uses changed: file -> start.file or end.file (as needed),
8466 first_line -> start.line, first_column -> start.column,
8467 last_line -> end.line, last_column -> end.column.
8468 (equal_boundaries): New function.
8469 (LOCATION_RESET, LOCATION_STEP): Remove.
8470 (LOCATION_PRINT): Remove. All callers changed to use location_print.
8471 (empty_location): Now const.
8472 (location_print): New decl.
8473 * src/parse-gram.y (lloc_default): New function, which handles
8474 empty locations more accurately.
8475 (YYLLOC_DEFAULT): Use it.
8476 (%token COLON): Remove.
8477 (%token ID_COLON): New token.
8479 (declarations, rules): Remove trailing semicolon.
8480 (declaration, rules_or_grammar_declaration):
8481 Allow empty (";") declaration.
8482 (symbol_def): Remove empty actions; no longer needed.
8483 (rules_or_grammar_declaration): Remove trailing semicolon.
8484 (semi_colon.opt): Remove.
8485 * src/reader.h: Include location.h.
8486 (scanner_cursor): New decl.
8487 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
8489 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
8491 (STEP): Remove. No longer needed, now that adjust_location does
8492 the work. All uses removed.
8493 (scanner_cursor): New var.
8494 (adjust_location): Renamed from extend_location. It now sets
8495 *loc and adjusts the scanner cursor. All uses changed.
8496 Don't bother testing for CR.
8497 (handle_syncline): Remove location arg; now updates scanner cursor.
8498 All callers changed.
8499 (unexpected_end_of_file): Now accepts start boundary of token or
8500 comment, not location. All callers changed. Update scanner cursor,
8502 (SC_AFTER_IDENTIFIER): New state.
8503 (context_state): Renamed from c_context. All uses changed.
8504 (id_loc, code_start, token_start): New local vars.
8505 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
8506 processing of Yacc white space and equivalents here.
8507 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
8508 instead of returning ID immediately, since we need to search for
8510 (<INITIAL>"'", "\""): Save token_start.
8511 (<INITIAL>"%{", "{", "%%"): Save code_start.
8512 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
8513 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
8514 BEGIN context_state at end, not INITIAL.
8515 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
8516 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
8517 Return correct token start.
8518 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
8519 the start of a character, string or multiline comment is found.
8520 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
8521 Reduction): Adjust reported locations to match the more-precise
8522 results now expected.
8523 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
8524 * tests/reduce.at (Useless Rules, Reduced Automaton,
8525 Underivable Rules): Likewise.
8526 * tests/regression.at (Invalid inputs): No longer `expecting ";"
8527 or "|"' now that so many other tokens are allowed by the new grammar.
8529 * src/complain.h (current_file): Remove duplicate decl;
8530 current_file is now owned by files.h.
8531 * src/complain.c, src/scan-gram.l: Include files.h.
8533 2002-12-06 Paul Eggert <eggert@twinsun.com>
8535 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
8536 promotes to int; it might be unsigned int.
8537 * data/yacc.c (yy_reduce_print): Likewise.
8539 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
8540 be #defined in the prologue, not in the Bison declarations.
8541 This fixes Debian Bug 102878, reported by Shaul Karl.
8543 2002-12-02 Paul Eggert <eggert@twinsun.com>
8545 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
8546 * lib/strtoul.c: New file, from gnulib.
8547 This fixes a porting bug reported by Peter Klein in
8548 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
8550 2002-11-30 Paul Eggert <eggert@twinsun.com>
8552 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
8553 and put only a forward declaration in the prologue. This is for
8554 consistency with the other scanner helper functions.
8556 Type clashes now generate warnings, not errors, since it
8557 appears that POSIX may allow some grammars with type clashes.
8558 * src/reader.c (grammar_current_rule_check): Warn about
8559 type clashes instead of complaining.
8560 * tests/input.at (Type Clashes): Expect warnings, not complaints.
8562 Add Yacc library, since POSIX requires it.
8563 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
8564 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
8565 * lib/main.c, lib/yyerror.c: New files.
8567 gram_error can be static; it need not be extern.
8568 * src/reader.h (gram_error): Remove decl.
8569 * src/parse-gram.y (gram_error): Now static. Add static decl.
8570 (print_token_value): Omit parameter names from forward decl,
8573 2002-11-29 Paul Eggert <eggert@twinsun.com>
8575 * doc/bison.texinfo: Emphasize that yylex and yyerror must
8576 be declared before being used. E.g., one should typically
8577 declare them in the prologue. Use GNU coding style in examples.
8578 Put "const" consistently after the type it modifies. Mention
8579 that C99 supports "inline". Mention that yyerror traditionally
8582 %parse-param and %lex-param now take just one argument, the
8583 declaration; the argument name is deduced from the declaration.
8585 * doc/bison.texinfo (Parser Function, Pure Calling, Error
8586 Reporting, Table of Symbols): Document this.
8587 * src/parse-gram.y (add_param): New function.
8589 (declaration): Implement new rule for %parse-param and %lex-param.
8590 * src/scan-gram.l: "," now elicits a warning, rather than being
8591 a token; this is more compatible with byacc.
8592 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
8594 2002-11-27 Paul Eggert <eggert@twinsun.com>
8596 Rename identifiers to avoid real and potential collisions.
8598 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
8599 to avoid collision with lex macro described by Bruce Lilly in
8600 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
8601 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
8602 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
8603 * src/parse-gram.y (print_token_value): Renamed from yyprint.
8605 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
8606 The name "yycontrol" violates the name space rules, and this stuff
8607 wasn't being used anyway.
8608 (input): Remove action; this stuff wasn't being used.
8609 (gram_error): Rename local variable yylloc -> loc.
8610 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
8611 (YY_DECL): Don't use "yy" at start of local variables.
8612 All uses changed, e.g., yylloc -> loc.
8613 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
8614 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
8615 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
8616 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
8618 * src/parse-gram.y (gram_error): loc is now const *.
8619 * src/reader.h (gram_error): Likewise.
8621 2002-11-24 Paul Eggert <eggert@twinsun.com>
8625 * tests/actions.at (Actions after errors): Use an output format
8626 more similar to that of the Printers and Destructors test.
8627 Test the position of the ';' token too.
8628 (Printers and Destructors): Likewise.
8629 (Printers and Destructors: %glr-parser): Remove for now, to avoid
8630 unnecessarily alarming people when the test fails.
8632 * data/yacc.c (yyerrlab1): Move this label down, so that the
8633 parser does not discard the lookahead token if the user code
8634 invokes YYERROR. This change is required for POSIX conformance.
8636 * lib/error.c: Sync with gnulib.
8638 2002-11-22 Paul Eggert <eggert@twinsun.com>
8640 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
8641 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
8642 * lib/xmalloc.c: Likewise.
8644 2002-11-20 Paul Eggert <eggert@twinsun.com>
8646 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
8648 2002-11-20 Paul Eggert <eggert@twinsun.com>
8650 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
8651 should use `if (! x) abort ();' rather than `assert (x);', and
8652 anyway it's one less thing to worry about configuring.
8654 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
8655 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
8656 and replace all instances of assert with abort.
8657 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
8658 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
8660 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
8661 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
8662 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
8663 hash_find_entry, hash_rehash, hash_insert): Likewise.
8664 * src/conflicts.c (resolve_sr_conflict): Likewise.
8665 * src/lalr.c (set_goto_map, map_goto): Likewise.
8666 * src/nullable.c (nullable_compute): Likewise.
8667 * src/output.c (prepare_rules, token_definitions_output): Likewise.

8672 symbol_pack): Likewise.
8673 * src/tables.c (conflict_row, pack_vector): Likewise.
8674 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
8675 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
8676 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
8677 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
8679 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
8680 (ARGMATCH_CONSTRAINT): New macro.
8681 (ARGMATCH_ASSERT): Use it.
8683 * src/system.h (verify): New macro.
8684 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
8686 * src/tables.c (tables_generate): Likewise.
8688 * src/struniq.c (struniq_assert): Now returns void, and aborts
8689 if the assertion is false.
8690 (struniq_assert_p): Remove.
8691 * src/struniq.h: Likewise.
8693 2002-11-18 Paul Eggert <eggert@twinsun.com>
8695 * data/glr.c (yygetLRActions): Replace `yyindex' with
8696 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
8697 This fixes the regression with Sun ONE Studio 7 cc that I reported in
8698 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
8700 2002-11-18 Akim Demaille <akim@epita.fr>
8702 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
8704 From Tim Van Holder.
8706 2002-11-17 Paul Eggert <eggert@twinsun.com>
8708 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
8709 to "SyntaxError" for consistency with my 2002-11-15 change.
8711 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
8712 not define to {}, since this breaks the common use of `YYDPRINTF
8713 ((...));' if a single statement is desired (e.g. before `else').
8714 Work around GCC warnings by surrounding corresponding calls with
8716 (yyhasResolvedValue): Remove unused function.
8717 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
8719 (yyreportSyntaxError): Renamed from yyreportParseError.
8720 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
8722 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
8723 extern when possible. Remove unused initializations.
8725 2002-11-16 Akim Demaille <akim@epita.fr>
8727 Augment the similarity between GLR and LALR traces.
8729 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
8730 (YY_REDUCE_PRINT): New.
8731 (yyparse): Use them.
8732 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
8734 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
8735 state reached after the reduction/recovery, since...
8736 (yyparse, yyprocessOneStack): Report the state we are entering in.
8738 2002-11-16 Akim Demaille <akim@epita.fr>
8740 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
8741 Add support for --trace=skeleton.
8742 * src/scan-skel.l: %option debug.
8743 Scan strings of non-@ or \n instead of character by character.
8744 (scan_skel): Handle trace_skeleton.
8746 (@output_parser_name@, @output_header_name@): ``Restore'' their
8747 support (used to be M4 macros).
8748 * data/yacc.c: Quote larger chunks, a la glr.c.
8749 * data/lalr1.cc: Likewise.
8750 The header guards are no longer available, so use some other
8751 string than `YYLSP_NEEDED'.
8753 2002-11-16 Akim Demaille <akim@epita.fr>
8755 Make the ``Printers and Destructors'' test more verbose, taking
8756 `yacc.c''s behavior as (possibly wrong) reference.
8758 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
8759 instead of fprint on stdout.
8760 Set and report the last_line of the symbols.
8761 Consistently display values and locations.
8763 2002-11-16 Paul Eggert <eggert@twinsun.com>
8765 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
8767 2002-11-15 Paul Eggert <eggert@twinsun.com>
8769 * tests/actions.at (Actions after errors): New test case.
8771 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
8772 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
8773 tests/action.at, tests/calc.at, tests/conflicts.at,
8774 tests/cxx-type.at, tests/regression.at:
8775 "parse error" -> "syntax error" for POSIX compatibility.
8776 "parsing stack overflow..." -> "parser stack overflow" so
8777 that code matches Bison documentation.
8779 2002-11-15 Akim Demaille <akim@epita.fr>
8781 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
8782 take two BRACED_CODE, not two string_content.
8783 Free the scanner's obstack when we are done.
8784 (code_content): New.
8785 * tests/calc.at: Adjust.
8786 * doc/bison.texinfo: Adjust.
8787 Also, make sure to include the `,' for these declarations.
8789 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
8791 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
8792 definition; avoids potential autoreconf problems.
8794 2002-11-15 Akim Demaille <akim@epita.fr>
8796 Always check the value returned by yyparse.
8798 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
8799 returned by yyparse.
8800 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
8802 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
8803 returned by yyparse.
8805 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
8807 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
8810 2002-11-14 Paul Eggert <eggert@twinsun.com>
8812 * src/output.c (output_skeleton): Call xfopen instead of
8813 duplicating xfopen's body.
8815 Fix bugs reported by Nelson H. F. Beebe in
8816 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
8818 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
8819 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
8820 Group compiler. Instead, use "$CC -E bar.c". Include the .h
8821 file twice in the grammar, as an extra check.
8823 * tests/input.at (Torturing the Scanner): Surround the
8824 backslash-newline tests with "#if 0", to make it less likely that
8825 we'll run into compiler bugs. Bring back solitary \ inside
8826 comment, but add a closing comment to work around HP C bug. Don't
8827 test backslash-newline in C character constant.
8829 2002-11-14 Akim Demaille <akim@epita.fr>
8831 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
8832 status of the compiler.
8833 Calling `exit 1' is no longer needed.
8834 Reported by Nelson H. F. Beebe.
8836 2002-11-14 Akim Demaille <akim@epita.fr>
8838 * tests/atlocal.in (CPPFLAGS): We have config.h.
8839 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
8841 * tests/actions.at, tests/calc.at, tests/conflicts.at,
8842 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
8843 * tests/regression.at, tests/torture.at: Use them for all the
8844 grammars that are to be compiled.
8845 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
8846 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
8847 * doc/bison.texinfo (GLR Parsers): Document `inline'.
8849 2002-11-14 Akim Demaille <akim@epita.fr>
8851 * doc/bison.texinfo: Various formatting changes (alignments in
8852 samples, additional @group/@end group, GCS in samples.
8853 Use @deffn instead of simple @table to define the directives,
8854 macros, variables etc.
8856 2002-11-13 Paul Eggert <eggert@twinsun.com>
8858 Fix some bugs reported by Albert Chin-A-Young in
8859 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
8861 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
8862 -o c"; the HP C compiler chatters during compilation.
8863 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
8864 * tests/headers.at (export YYLTYPE): Likewise.
8866 * tests/input.at (Torturing the Scanner): Remove lines containing
8867 solitary backslashes, as they tickle a bug in the HP C compiler.
8869 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
8870 comments, since they're not portable. Use GNU coding style.
8872 2002-11-13 Akim Demaille <akim@epita.fr>
8874 * data/yacc.c: Leave bigger chunks of quoted text.
8875 (YYDSYMPRINTF): New.
8876 Use it to report symbol activities.
8877 * data/glr.c (YYDSYMPRINTF): New.
8880 2002-11-12 Paul Eggert <eggert@twinsun.com>
8884 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
8885 (yyglrReduce): Return yyok, not 0.
8886 This should avoid the enumerated-type warnings reported
8887 by Nelson H. F. Beebe in
8888 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
8890 * lib/bbitset.h (BITSET_INLINE): Remove.
8891 * lib/bitset.h [! BITSET_INLINE]: Remove.
8892 (bitset_set, bitset_reset, bitset_test): Rename local vars
8893 to avoid shadowing warnings by GCC.
8895 * data/glr.c (inline): Remove #define. It's the user's
8896 responsibility to #define it away, just like 'const'.
8897 This fixes one of the bugs reported by Nelson H. F. Beebe in
8898 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
8900 * Makefile.maint (po-check): Scan .l and .y files instead of the
8901 .c and the .h files that they generate. This fixes the bug
8902 reported by Tim Van Holder in:
8903 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
8904 Look for N_ as well as for _. Try to avoid matching #define for
8906 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
8907 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
8908 * src/scan-gram.l: Revamp regular expressions so that " and '
8909 do not confuse xgettext.
8911 * src/struniq.h (struniq_new): Do not declare the return type
8912 to be 'const'; this violates the C standard.
8913 * src/struniq.c (struniq_new): Likewise.
8915 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
8917 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
8918 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
8921 2002-11-12 Akim Demaille <akim@epita.fr>
8923 * Makefile.maint: Sync with Autoconf:
8924 (local_updates): New.
8926 2002-11-12 Akim Demaille <akim@epita.fr>

8935 2002-11-12 Akim Demaille <akim@epita.fr>
8937 * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT,
8940 2002-11-12 Akim Demaille <akim@epita.fr>
8942 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
8943 Use it to test the GLR parser.
8945 2002-11-12 Akim Demaille <akim@epita.fr>
8947 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
8949 * data/glr.c (yystos): New.
8950 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
8952 (yyval): Don't define it, it is handled via M4.
8953 (yyrecoverParseError): Free verbosely the discarded symbols.
8954 * data/yacc.c (yysymprint): Remove, rather...
8955 (b4_yysymprint_generate): invoke.
8956 * data/c.m4 (b4_yysymprint_generate): New.
8957 Accept pointers as arguments, as opposed to the version from
8959 (b4_yydestruct_generate): Likewise.
8960 * tests/cations.at (Printers and Destructors): Use Bison directives
8961 instead of CPP macros.
8962 Don't rely on internal details.
8964 2002-11-12 Akim Demaille <akim@epita.fr>
8966 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
8967 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
8968 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
8969 it against YYEMPTY and so forth), work on yytoken (i.e., set
8970 it to YYEMPTY etc.).
8971 (yydestruct): Replace with a b4_yydestruct_generate invocation.
8972 (b4_symbol_actions): Remove.
8973 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
8974 for 0, end-of-input.
8976 2002-11-12 Akim Demaille <akim@epita.fr>
8978 * doc/bison.texinfo (Destructor Decl): New.
8980 2002-11-12 Akim Demaille <akim@epita.fr>
8982 * src/tables.c (tables_generate): Use free for pointers that
8983 cannot be NULL, not XFREE.
8984 (pack_vector): Use assert, not fatal, for bound violations.
8985 * src/state.c (state_new): Likewise.
8986 * src/reader.c (reader): Likewise.
8987 * src/lalr.c (set_goto_map): Likewise.
8988 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
8991 2002-11-12 Akim Demaille <akim@epita.fr>
8993 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
8995 * src/scan-gram.l (last_string): Is global to the file, not to
8997 * src/parse-gram.y (input): Don't append the epilogue here,
8998 (epilogue.opt): do it here, and free the scanner's obstack.
8999 * src/reader.c (epilogue_set): Rename as...
9000 (epilogue_augment): this.
9001 * data/c.m4 (b4_epilogue): Defaults to empty.
9003 2002-11-12 Akim Demaille <akim@epita.fr>
9005 * src/getargs.c (long_options): Remove duplicates.
9006 * src/vmsgetargs.c, src/build.com, src/bison.cld, src/vmshlp.mar:
9008 * doc/bison.rnh: Remove.
9009 * doc/bison.texinfo (VMS Invocation): Remove.
9011 2002-11-12 Akim Demaille <akim@epita.fr>
9013 * src/struniq.h, src/struniq.c (struniq_t): Is const.
9014 (STRUNIQ_EQ, struniq_assert, struniq_assert_p): New.
9016 Use struniq for symbols.
9018 * src/symtab.h (symbol_t): The tag member is a struniq.
9019 (symbol_type_set): Adjust.
9020 * src/symtab.c (symbol_new): Takes a struniq.
9021 (symbol_free): Don't free the tag member.
9022 (hash_compare_symbol_t, hash_symbol_t): Rename as...
9023 (hash_compare_symbol, hash_symbol): these.
9024 Use the fact that tags as struniqs.
9025 (symbol_get): Use struniq_new.
9026 * src/symlist.h, src/symlist.c (symbol_list_n_type_name_get):
9028 * src/reader.h (merger_list, grammar_currentmerge_set): The name
9029 and type members are struniqs.
9030 * src/reader.c (get_merge_function)
9031 (grammar_current_rule_merge_set): Adjust.
9032 (TYPE, current_type): Are struniq.
9034 Use struniq for file names.
9036 * src/files.h, src/files.c (infile): Split into...
9037 (grammar_file, current_file): these.

9040 * src/getargs.c (getargs): Likewise.
9041 * src/complain.h, src/complain.c: Likewise.
9042 * src/main.c (main): Call struniqs_new early enough to use it for
9044 Don't free the input file name.
9046 2002-11-12 Akim Demaille <akim@epita.fr>
9048 * src/symtab.c (symbol_free): Remove dead deactivated code:

9059 2002-11-11 Paul Eggert <eggert@twinsun.com>
9061 Revamp to fix many (but not all) of the C- and M4-related quoting
9062 problems. Among other things, this fixes the Bison bug reported
9063 by Jan Hubicka when processing the Bash grammar; see:
9064 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
9066 Use new @ escapes consistently. Represent brackets with @{ and @}
9067 rather than @<:@ and @:>@, since this works a bit better with dumb
9068 editors like vi. Represent @ with @@, since @ is now consistently
9069 an escape. Use @oline@ and @ofile@ rather than __oline__ and
9070 __ofile__, to avoid unexpected expansions. Similarly, use @output
9071 rather than #output.
9073 * data/c.m4 (b4_copyright): Omit file name from comment, since
9074 the file name could contain "*/".
9075 (b4_synclines_flag): Don't quote the 2nd argument; it should already
9076 be quoted. All uses changed.
9078 * data/glr.c: Use new @ escapes consistently.
9079 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
9080 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
9081 Remove, since they couldn't handle arbitrary characters in file
9083 * data/lalr1.cc: Likewise.
9084 * data/yacc.c: Likewise.
9086 * src/files.c (output_infix): Remove; all uses removed.
9087 * src/files.h: Likewise.
9089 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
9090 mishandled funny characters in file names, and anyway it isn't
9092 * data/yacc.c: Likewise.
9093 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
9095 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
9096 * data/yacc.c: Likewise.
9098 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
9100 (muscle_init): Quote filename as a C string.
9101 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
9102 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
9103 * src/output.c (escaped_file_name_output): New function.
9104 (prepare_symbols): Quote tokens for M4.
9105 (prepare): Don't insert output_infix, output_prefix,
9106 output_parser_name, output_header_name; this is now down by scan-skel.
9107 Insert skeleton as a C string.
9109 * src/output.c (user_actions_output, symbol_destructors_output,
9110 symbol_printers_output): Quote filenames for C and M4.
9111 * src/reader.c (prologue_augment, epilogue_set): Likewise.
9113 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
9114 escapes other than \\ and \'; this simplifies the code.
9115 (<SC_STRING>): Likewise, for \\ and \".
9116 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
9117 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
9118 Use new escapes @{ and @} for [ and ].
9120 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
9121 them with auto vars.
9122 Switch to new escape scheme, where @ is the escape character uniformly.
9123 Abort if a stray escape character is found. Avoid unbounded input
9124 buffer when parsing non-escaped text.
9126 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
9127 __oline__, #output, $@, and @{ do not have unintended meanings.
9129 2002-11-09 Paul Eggert <eggert@twinsun.com>
9131 Fix the test failure due to GCC warnings described in
9132 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
9133 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
9134 evaluate to 0 if it's impossible for NINF to be in the respective
9136 (yygetLRActions, yyrecoverParseError): Use them.
9138 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
9139 counted in the token inserted at end of file. Now takes
9140 location_t *, not location_t, so that the location can be
9141 adjusted. All uses changed.
9143 * tests/regression.at (Invalid inputs): Adjust wording in
9144 diagnostic to match the new behavior.
9146 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
9147 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
9148 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
9149 abort ();'. This reduces the runtime of the "Many lookaheads"
9150 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
9153 2002-11-07 Paul Eggert <eggert@twinsun.com>
9155 * src/parse-gram.y (CHARACTER): Remove unused token.
9158 * src/scan-gram.l: Remove stack option. We no longer use the
9159 stack, since the stack was never deeper than 1; instead, use the
9160 new auto var c_context to record the stacked value.
9162 Remove nounput option. At an unexpected end of file, we now unput
9163 the minimal input necessary to end cleanly; this simplifies the
9166 Avoid unbounded token sizes where this is easy.
9168 (unexpected_end_of_file): New function.
9169 Use it to systematize the error message on unexpected EOF.

9246 as POSIX 1003.1-2001 requires.
9247 * src/system.h (IF_LINT): New macro, taken from coreutils.
9248 * configure.ac: Define "lint" if --enable-gcc-warnings.
9250 2002-11-05 Akim Demaille <akim@epita.fr>
9252 * src/scan-gram.l: When it starts with `%', complain about the

9269 2002-11-04 Akim Demaille <akim@epita.fr>
9271 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
9273 * src/scan-gram.l: Use [\'] instead of ['] to pacify
9276 Use quote, not quote_n since LOCATION_PRINT no longer uses the
9279 2002-11-03 Paul Eggert <eggert@twinsun.com>
9281 * src/reader.c (get_merge_function, grammar_current_rule_check):
9282 Use consistent diagnostics for reporting type name clashes.
9283 Quote the types with <>, for consistency with Yacc.

9298 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
9299 b4_user_formals and b4_user_args.
9300 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
9301 (yyreportAmbiguity): When using a pure parser, also need
9302 the location, and the parse-params.
9304 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
9305 When using a pure parser, also need the parse-params.
9307 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
9308 (%pure-parser + %parse-param) LALR and GLR parsers.
9309 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
9310 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,

9328 2002-11-03 Paul Eggert <eggert@twinsun.com>
9330 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
9331 to count columns correctly, and to check for invalid inputs.
9333 Use mbsnwidth to count columns correctly. Account for tabs, too.
9335 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
9336 (extend_location): New function.
9339 Handle CRLF in C code rather than in Lex code.

9343 Scan UCNs, even though we don't fully handle them yet.
9344 (convert_ucn_to_byte): New function.
9346 Handle backslash-newline correctly in C code.
9347 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
9348 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;

9355 (letter, id): Don't assume ASCII; e.g., spell out a-z.
9357 ({int}, handle_action_dollar, handle_action_at): Check for integer
9360 (YY_STEP): Omit trailing semicolon, so that it's more like C.
9362 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
9363 as well as \000. Check for UCHAR_MAX, not 255.
9364 Allow \x with an arbitrary positive number of digits, as in C.
9365 Check for overflow here.
9366 Allow \? and UCNs, for compatibility with C.
9368 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
9369 with quote slot used by complain_at.
9371 * tests/input.at: Add tests for backslash-newline, m4 quotes
9372 in symbols, long literals, and funny escapes in strings.
9374 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
9375 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.

9388 2002-11-02 Paul Eggert <eggert@twinsun.com>
9390 * src/reader.c: Don't include quote.h; not needed.

9395 bug in trigraph handling.
9397 * src/output.c (prepare_symbols): When printing token names,
9398 escape "[" as "@<:@" and likewise for "]".
9400 * src/system.h (errno): Remove declaration, as we are now
9401 assuming C89 or better, and C89 guarantees errno.
9403 2002-10-30 Paul Eggert <eggert@twinsun.com>
9405 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
9406 Check for close failures.
9407 * src/files.h (xfclose): Return void, not int, since it always
9409 * src/files.c (xfclose): Likewise. Report I/O error if ferror
9411 * src/output.c (output_skeleton): Use xfclose rather than fclose
9412 and ferror. xfclose now checks ferror.
9414 * data/glr.c (YYLEFTMOST_STATE): Remove.
9415 (yyreportTree): Use a stack-based leftmost state. This avoids
9416 our continuing battles with bogus warnings about initializers.
9418 2002-10-30 Akim Demaille <akim@epita.fr>
9420 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only

9433 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
9434 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
9435 we use malloc. Don't assume 'A' through 'Z' are contiguous.
9436 Don't assume strdup exists; POSIX says its an XSI extension.
9437 Check for buffer overflow on input.
9439 2002-10-24 Akim Demaille <akim@epita.fr>
9441 * src/output.c (output_skeleton): Don't disable M4sugar comments
9442 too soon: it results in comments being expanded.
9443 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
9446 2002-10-24 Akim Demaille <akim@epita.fr>
9448 * data/yacc.c (m4_int_type): New.
9449 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
9450 char' as only yacc.c wants K&R portability.

9452 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
9453 Reported by Quoc Peyrot.
9455 2002-10-23 Paul Eggert <eggert@twinsun.com>
9457 * src/main.c (main): With --trace=time, report times even if a
9458 non-fatal error occurs. Formerly, the times were reported in some
9459 such cases but not in others.
9460 * src/reader.c (reader): Just return if a complaint has been issued,
9461 instead of exiting, so that 'main' can report times.
9463 2002-10-22 Akim Demaille <akim@epita.fr>
9465 * src/system.h: Include sys/types.
9466 Reported by Bert Deknuydt.
9468 2002-10-23 Paul Eggert <eggert@twinsun.com>
9470 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
9471 Suggested by Art Haas.

9475 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
9476 decl; not needed any more.
9477 * src/main.c (main): Use return to exit, undoing yesterday's change.
9478 The last OS that we could find where this wouldn't work is
9479 SunOS 3.5, and that's too old to worry about now.
9481 * data/glr.c (struct yyltype): Define members even when not
9482 doing locations. This is more consistent with yacc.c, and it
9483 works around the following bug reports:
9484 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
9485 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
9487 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
9488 @acronym consistently. Standardize on "Yacc" instead of "YACC",
9489 "Algol" instead of "ALGOL". Give a bit more history about BNF.
9491 2002-10-22 Akim Demaille <akim@epita.fr>
9495 2002-10-21 Paul Eggert <eggert@twinsun.com>
9497 Be consistent about 'bool'; the old code used an enum in one
9498 module and an int in another, and this violates the C standard.
9499 * m4/stdbool.m4: New file, from coreutils 4.5.3.
9500 * configure.ac (AC_HEADER_STDBOOL): Add.
9501 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
9502 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
9503 * src/symtab.c (hash_compare_symbol_t): Likewise.
9504 * src/system.h (bool, false, true): Use a definition consistent
9505 with ../lib/hash.c. All uses changed.
9507 * src/complain.c (warning_issued): Renamed from warn_message_count,
9508 so that we needn't worry about integer overflow (!).
9509 Now of type bool. All uses changed.
9510 (complaint_issued): Renamed from complain_message_count; likewise.
9512 * src/main.c (main): Use exit to exit with failure.
9514 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
9515 rather than 1 and 0.
9516 * src/main.c (main): Likewise.
9517 * src/getargs.c (getargs): Likewise.
9518 * src/reader.c (reader): Likewise.
9520 * src/getarg.c (getargs): Remove duplicate code for
9521 "Try `bison --help'".
9523 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
9524 What was that "2" for?
9526 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
9527 * src/getargs.c (usage): Likewise.
9529 * src/getargs.c (getargs): When there are too few operands, report
9530 the last one. When there are too many, report the first extra
9531 one. This is how diffutils does it.
9533 2002-10-20 Paul Eggert <eggert@twinsun.com>
9535 Remove K&R vestiges.
9536 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
9537 * src/complain.c (VA_START): Remove. Assume prototypes.
9538 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
9539 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
9540 fatal): Assume prototypes.
9541 * src/complain.h: Assume prototypes.
9542 * src/system.h (PARAMS): Remove.
9543 Include <limits.h> unconditionally, since it's guaranteeed even
9544 for a freestanding C89 compiler.
9545 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
9546 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
9548 2002-10-20 Akim Demaille <akim@epita.fr>
9550 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.

9553 (yyresolveStates, yyresolveAction, yyresolveStack)
9554 (yyprocessOneStack): Use them.
9555 (yy_reduce_print): New.

9564 (b4_c_function_decl, b4_c_ansi_function_def)
9565 (b4_c_ansi_function_decl): New.
9566 Change the interpretation of the arguments: before `int, foo', now
9568 * data/yacc.c (yyparse): Prototype and define thanks to these.
9569 Adjust b4_c_function_def uses.
9570 * data/glr.c (yyparse): Likewise, but ANSI only.
9572 2002-10-20 Akim Demaille <akim@epita.fr>
9574 * src/output.c (prepare): Move the definition of `tokens_number',
9575 `nterms_number', `undef_token_number', `user_token_number_max'
9577 (prepare_tokens): Here.
9578 (prepare_tokens): Rename as...
9579 (prepare_symbols): this.
9580 (prepare): Move the definition of `rules_number' to...
9581 (prepare_rules): here.
9582 (prepare): Move the definition of `last', `final_state_number',
9583 `states_number' to...
9584 (prepare_states): here.
9585 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
9587 2002-10-20 Akim Demaille <akim@epita.fr>

9591 2002-10-20 Akim Demaille <akim@epita.fr>

9596 2002-10-20 Akim Demaille <akim@epita.fr>
9598 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
9599 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
9601 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
9603 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
9604 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
9607 2002-10-19 Paul Eggert <eggert@twinsun.com>
9609 Do not create a temporary file, as that involves security and
9610 cleanup headaches. Instead, use a pair of pipes.
9611 Derived from a suggestion by Florian Krohm.
9612 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
9613 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.

9622 (scan_skel): New decl.
9623 (output_skeleton): Use pipe rather than temporary file for m4 input.
9624 Check that m4sugar.m4 is readable, to avoid deadlock.
9625 Check for pipe I/O error.
9626 * src/scan-skel.l (readpipe): Remove decl.
9627 (scan_skel): New function, to be used in place of m4_invoke.
9628 Read from stream rather than file.
9630 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
9631 float, as this generates a warning on Solaris 8 + GCC 3.2 with
9632 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
9633 this generates a more-accurate value anyway.
9635 * lib/timevar.c (timervar_accumulate): Rename locals to
9636 avoid confusion with similarly-named more-global.
9637 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
9639 * src/output.c (prepare): Use xstrdup to convert char const *
9640 to char *, to avoid GCC warning.
9642 2002-10-19 Akim Demaille <akim@epita.fr>
9644 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,

9647 * data/yacc.c (YYLEX): Pass a yylex return type to
9650 2002-10-19 Akim Demaille <akim@epita.fr>
9652 Prototype support of %lex-param and %parse-param.
9654 * src/parse-gram.y: Add the definition of the %lex-param and
9655 %parse-param tokens, plus their rules.
9656 Drop the `_' version of %glr-parser.
9658 * src/scan-gram.l (INITIAL): Scan them.
9659 * src/muscle_tab.c: Comment changes.
9660 (muscle_insert, muscle_find): Rename `pair' as `probe'.
9661 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
9662 (muscle_entry_s): The `value' member is no longer const.
9663 Adjust all dependencies.
9664 * src/muscle_tab.c (muscle_init): Adjust: use
9665 MUSCLE_INSERT_STRING.
9666 Initialize the obstack earlier.
9667 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
9668 (muscle_pair_list_grow): New.
9669 * data/c.m4 (b4_c_function_call, b4_c_args): New.
9670 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
9671 * tests/calc.at: Use %locations, not --locations.
9672 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
9674 2002-10-19 Akim Demaille <akim@epita.fr>
9676 * src/getargs.c (usage): Take status as argument and exit
9678 Report the traditional `Try ... --help' message when status != 0.
9679 (usage, version): Don't take a FILE * as arg, it is pointless.
9680 (getargs): When there is an incorrect number of arguments, make it
9681 an error, and report it GNUlically thanks to `usage ()'.
9683 2002-10-18 Paul Eggert <eggert@twinsun.com>
9685 * data/glr.c (yyreportParseError): Don't assume that sprintf
9686 yields the length of the printed string, as this is not true
9687 on SunOS 4.1.4. Reported by Peter Klein.
9689 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
9690 * tests/conflicts.at (%nonassoc and eof): Likewise.
9691 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
9693 2002-10-17 Akim Demaille <akim@epita.fr>
9695 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
9696 * src/getargs.c (trace_types, trace_args): Adjust.
9697 * src/reader.c (grammar_current_rule_prec_set)
9698 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
9699 Standardize error messages.
9701 (reader): Use trace_flag to enable scanner/parser debugging,
9702 instead of an adhoc scheme.
9703 * src/scan-gram.l: Remove trailing debugging code.
9705 2002-10-16 Paul Eggert <eggert@twinsun.com>
9707 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
9710 * NEWS: Officially drop support for building Bison with K&R C,
9711 since it didn't work anyway and it's not worth worrying about.
9712 * Makefile.maint (wget_files): Remove ansi2knr.c.
9713 (ansi2knr.c-url_prefix): Remove.
9714 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
9715 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
9716 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
9718 2002-10-15 Paul Eggert <eggert@twinsun.com>
9720 Stop using the "enum_" trick for K&R-style function definitions;
9721 it confused me, and I was the author! Instead, assume that people
9722 who want to use K&R C compilers (when using these modules in GCC,
9723 perhaps?) will run ansi2knr.
9725 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
9726 All uses of "enum_" changed to "enum ".

9738 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):

9740 static functions simply to provide their prototypes.

9802 2002-10-14 Akim Demaille <akim@epita.fr>
9804 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
9807 2002-10-14 Akim Demaille <akim@epita.fr>
9809 * src/tables.c (table_ninf_remap): base -> tab.
9810 Reported by Matt Rosing.
9812 2002-10-14 Paul Eggert <eggert@twinsun.com>

9815 tests/cxx-type.at, tests/headers.at, tests/input.at,
9816 tests/regression.at, tests/synclines.at, tests/torture.at:
9817 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
9818 so that the tests still work even if POSIXLY_CORRECT is set.
9819 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
9821 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
9822 for portability to K&R hosts. Fix typo: signed char is guaranteed
9823 only to 127, not to 128.
9824 * data/glr.c (yysigned_char): New type.
9825 * data/yacc.c (yysigned_char): Likewise.
9826 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
9828 2002-10-13 Paul Eggert <eggert@twinsun.com>
9830 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
9831 true due to limited range of data type" warning from GCC.
9833 * data/c.m4 (b4_token_defines): Protect against double-inclusion
9834 by wrapping enum yytokentype's definition inside #ifndef
9835 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
9837 2002-10-13 Akim Demaille <akim@epita.fr>
9839 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
9840 Un yy- yyrhs to avoid the name clash with the global YYRHS.
9842 2002-10-13 Akim Demaille <akim@epita.fr>
9844 * Makefile.maint: Update from Autoconf 2.54.
9845 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
9847 2002-10-13 Akim Demaille <akim@epita.fr>
9849 * src/print.c (print_state): Separate the list of solved conflicts
9850 from the other items.

9855 Let nondeterministic skeletons be usable with deterministic
9858 With the patch, GAWK compiled by GCC without -O2 passes its test
9859 suite using a GLR parser driven by LALR tables. It fails with -O2
9860 because `struct stat' gives two different answers on my machine:
9861 88 (definition of an auto var) and later 96 (memset on this var).
9862 Hence the stack is badly corrumpted. The headers inclusion is to
9863 blame: if I move the awk.h inclusion before GLR's system header
9864 inclusion, the two struct stat have the same size.
9866 * src/tables.c (pack_table): Always create conflict_table.
9867 (token_actions): Always create conflict_list.
9868 * data/glr.c (YYFLAG): Remove, unused.
9870 2002-10-13 Akim Demaille <akim@epita.fr>
9872 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
9874 (VALGRIND, GXX): New.
9875 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
9876 * tests/bison.in: Run $PREBISON a pre-command.

9883 * data/glr.c: Formatting changes.
9884 Tweak some trace messages to match yacc.c's.
9886 2002-10-13 Akim Demaille <akim@epita.fr>
9888 GLR parsers sometimes raise parse errors instead of performing the
9890 Reported by Charles-Henry de Boysson.
9892 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
9893 check the length of the traces when %glr.
9894 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
9896 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
9898 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
9899 (yyltype): Remove the yy prefix from the member names.
9900 (yytable): Complete its comment.
9901 (yygetLRActions): Map error action number from YYTABLE from
9903 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
9904 (which was a bug: it should have been YYTABEL_NINF, and yet it was
9905 not satisfying as we could compare an YYACTION computed from
9906 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
9907 only value for error actions.
9908 (yyreportParseError): In verbose parse error messages, don't issue
9909 `error' in the list of expected tokens.
9910 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
9911 next action to perform to match glr.c's decoding.
9912 (yytable): Complete its comment.

9916 Fix problem reported by Henrik Grubbstroem in
9917 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
9918 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
9919 because the Bison parser reads the second action before reducing
9921 * src/scan-gram.l (rule_length): New static var.
9922 Use it to keep track of the rule length in the scanner, since
9923 we can't expect the parser to be in lock-step sync with the scanner.
9924 (handle_action_dollar, handle_action_at): Use this var.
9925 * tests/actions.at (Exotic Dollars): Test for the problem.
9927 2002-10-12 Paul Eggert <eggert@twinsun.com>
9929 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
9930 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
9931 Include <sys/time.h> when checking for clock_t and struct tms.
9932 Use same include order as source.
9933 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
9934 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
9936 * lib/timevar.c: Update copyright date and clarify comments.
9937 (get_time) [IN_GCC]: Keep the GCC version for reference.
9939 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
9940 GCC version as of today, then merge Bison's changes.
9941 Change "GCC" to "Bison" in copyright notice. timevar.def's
9942 author is Akim, so change that too.
9944 * src/reader.c (grammar_current_rule_check):
9945 Don't worry about the default action if $$ is untyped.
9946 Prevents bogus warnings reported by Jim Gifford in
9947 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
9949 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
9950 * data/glr.c, data/lalr1.cc, data/yacc.c:
9951 Output token definitions before the first part of user declarations.
9952 Fixes compatibility problem reported by Jim Gifford for kbd in
9953 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.

10433 to void, to avoid a GCC warning when --disable-nls is in effect.
10435 * src/scan-gram.l: Use strings rather than escapes when possible,
10436 to minimize the number of warnings from xgettext.
10437 (handle_action_dollar, handle_action_at): Don't use isdigit,
10438 as it mishandles negative chars and it may not work as expected
10439 outside the C locale.
10441 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
10442 this is a GCC extension and is not portable to other compilers.

10487 `lookaheads_rule' member.

10681 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
10682 for the time being: %locations ought to provide it to yyerror.

12942 * lib/tempname.c, lib/mkstemp.c, m4/mkstemp.m4: New, stolen from
12944 * configure.in: Invoke UTILS_FUNC_MKSTEMP.
12945 * src/output.c (output_skeleton): Use mkstemp to create a real
12947 Move the filling of `skeleton' and its muscle to...
12949 (output): Move the definition of the prologue muscle to...
12951 * src/system.h (DEFAULT_TMPDIR): New.
12953 2002-02-14 Paul Eggert <eggert@twinsun.com>
12955 Remove the support for C++ namespace cleanliness; it was
12956 causing more problems than it was curing, since it didn't work
12957 properly on some nonstandard C++ compilers. This can wait
12958 for a proper C++ parser.
12960 * NEWS: Document this.
12961 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
12962 of C++, as it's treated like C now.
12963 * src/bison.simple (YYSTD): Remove.
12964 (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
12965 Treat C++ just like Standard C instead of trying to support
12966 namespace cleanliness.
12968 2002-02-14 Akim Demaille <akim@epita.fr>
12970 * tests/regression.at (else): Adjust to Andreas' change.
12972 2002-02-14 Akim Demaille <akim@epita.fr>
12974 * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c.
12976 2002-02-13 Andreas Schwab <schwab@suse.de>
12978 * src/output.c (output_rule_data): Don't output NULL, it might
12979 not be defined yet.
12981 2002-02-11 Robert Anisko <robert@lrde.epita.fr>
12983 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
12984 (Copyright notice): Update.
12986 2002-02-11 Akim Demaille <akim@epita.fr>
12988 * tests/regression.at (%nonassoc and eof): Don't include
12989 nonportable headers.
12991 2002-02-08 Robert Anisko <robert@lrde.epita.fr>
12993 * data/bison.c++: Correct error recovery. Make the user able to
12994 initialize the starting location.
12996 2002-02-07 Akim Demaille <akim@epita.fr>
12998 * tests/input.at: New.
13000 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
13002 * data/bison.c++: Replace some direct m4 expansions by constants. Be
13003 more consistent when naming methods and variables. Put preprocessor
13004 directives around tables only needed for debugging.
13006 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
13008 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
13010 (yy::b4_name::parse): Use print_.
13012 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
13014 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
13016 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
13018 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
13020 (yy::b4_name::parse): Build verbose error messages, and use error_.
13022 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
13024 * data/bison.c++: Fix m4 quoting in comments.
13026 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
13028 * data/bison.c++: Adjust the parser code. Fix some muscles that were
13029 not expanded by m4.
13031 2002-02-05 Akim Demaille <akim@epita.fr>
13033 * data/bison.c++: Adjust to the M4 back end.
13034 More is certainly needed.
13036 2002-02-05 Akim Demaille <akim@epita.fr>
13038 Give a try to M4 as a back end.
13040 * lib/readpipe.c: New, from wdiff.
13041 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
13043 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
13044 specific values. Now it is m4 that performs the lookup.
13045 * src/parse-skel.y: Remove.
13046 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
13047 * src/output.c (actions_output, guards_output)
13048 (token_definitions_output): No longer keeps track of the output
13049 line number, hence remove the second argument.
13050 (guards_output): Check against the guard member of a rule, not the
13053 (output_skeleton): Don't look for the skeleton location, let m4 do
13055 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
13057 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
13058 (prepare): Given that for the time being changesyntax is not
13059 usable in M4, rename the muscles using `-' to `_'.
13060 Define `defines_flag', `output_parser_name' and `output_header_name'.
13061 * src/output.h (actions_output, guards_output)
13062 (token_definitions_output): Adjust prototypes.
13063 * src/scan-skel.l: Instead of scanning the skeletons, it now
13064 processes the output of m4: `__oline__' and `#output'.
13065 * data/bison.simple: Adjust to be used by M4(sugar).
13066 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
13068 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
13069 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
13070 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
13071 shamelessly stolen from CVS Autoconf.
13073 2002-02-05 Akim Demaille <akim@epita.fr>
13075 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
13076 * configure.in: Check for the declarations of free and malloc.
13077 * src/muscle_tab.c: Adjust.
13079 2002-02-05 Akim Demaille <akim@epita.fr>
13081 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
13082 which have no values.
13084 2002-02-05 Akim Demaille <akim@epita.fr>
13086 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
13089 2002-01-29 Paul Eggert <eggert@twinsun.com>
13091 * src/bison.simple (YYSIZE_T): Do not define merely because
13092 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
13093 On some platforms, <alloca.h> does not declare YYSTD (size_t).
13095 2002-01-27 Akim Demaille <akim@epita.fr>
13097 Fix `%nonassoc and eof'.
13099 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
13100 which were not properly copied! Replace
13101 memcpy (res->errs, src->errs, src->nerrs);
13103 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
13105 * tests/regression.at (%nonassoc and eof): Adjust to newest
13106 Autotest: `.' is not in the PATH.
13108 2002-01-27 Akim Demaille <akim@epita.fr>
13110 * tests/sets.at (AT_EXTRACT_SETS): New.
13111 (Nullable): Use it.
13114 2002-01-26 Akim Demaille <akim@epita.fr>
13116 * tests/actions.at, tests/calc.at, tests/headers.at,
13117 * tests/torture.at: Adjust to the newest Autotest which no longer
13118 forces `.' in the PATH.
13120 2002-01-25 Akim Demaille <akim@epita.fr>
13122 * tests/regression.at (%nonassoc and eof): New.
13123 Suggested by Robert Anisko.
13125 2002-01-24 Akim Demaille <akim@epita.fr>
13127 Bison dumps core when trying to complain about broken input files.
13128 Reported by Cris van Pelt.
13130 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
13131 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
13133 (Invalid inputs): Strengthen: exercise parse_percent_token.
13135 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
13137 * src/Makefile.am: Add bison.c++.
13138 * src/bison.c++: New skeleton.
13140 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
13144 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
13146 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
13148 2002-01-20 Marc Autret <marc@gnu.org>
13150 * src/files.c (compute_output_file_names): Fix
13152 2002-01-20 Marc Autret <marc@gnu.org>
13154 * tests/output.at: New test.
13155 * src/files.c (compute_base_names): Don't map extensions when
13156 the YACC flag is set, use defaults.
13157 Reported by Evgeny Stambulchik.
13159 2002-01-20 Marc Autret <marc@gnu.org>
13161 * src/system.h: Need to define __attribute__ away for non-GCC
13162 compilers as well (i.e., the vendor C compiler).
13163 Suggested by Albert Chin-A-Young.
13165 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
13167 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
13168 canonical definition.
13169 * src/system.h: Use the canonical definition for PARAMS (avoids
13170 a conflict with the macro from lib/hash.h).
13172 2002-01-11 Akim Demaille <akim@epita.fr>
13174 * configure.in: Use AC_FUNC_STRNLEN.
13175 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
13177 2002-01-09 Akim Demaille <akim@epita.fr>
13179 * src/files.c, src/files.h (output_infix): New.
13180 (tab_extension): Remove.
13181 (compute_base_names): Compute the former, drop the latter.
13182 * src/output.c (prepare): Insert the muscles `output-infix', and
13184 * src/parse-skel.y (string, string.1): New.
13185 (section.header): Use it.
13186 (section.yacc): Remove.
13187 (prefix): Remove too.
13188 * src/scan-skel.l: Adjust.
13189 * src/bison.simple, src/bison.hairy: Adjust.
13191 2002-01-09 Akim Demaille <akim@epita.fr>
13193 * configure.in (WERROR_CFLAGS): Compute it.
13194 * src/Makefile.am (CFLAGS): Pass it.
13195 * tests/atlocal.in (CFLAGS): Idem.
13196 * src/files.c: Fix a few warnings.
13197 (get_extension_index): Remove, unused.
13199 2002-01-08 Akim Demaille <akim@epita.fr>
13201 * src/getargs.c (AS_FILE_NAME): New.
13202 (getargs): Use it to convert DOSish file names.
13203 * src/files.c (base_name): Rename as full_base_name to avoid
13204 clashes with `base_name ()'.
13205 (filename_split): New.
13206 (compute_base_names): N-th rewrite, using filename_split.
13208 2002-01-08 Akim Demaille <akim@epita.fr>
13210 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
13211 New, stolen from the Fileutils 4.1.
13212 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
13213 * configure.in: Check for the presence of memrchr, and of its
13216 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
13218 * lib/hash.h (__P): Added definition for this macro.
13219 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
13220 BUILT_SOURCES, to ensure they are generated first.
13221 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
13222 %error-verbose to allow bootstrapping with bison 1.30x.
13224 2002-01-06 Akim Demaille <akim@epita.fr>
13226 * src/reader.c (parse_braces): Don't fetch the next char, the
13227 convention is to fetch on entry.
13228 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
13229 'switch' without a following semicolon.
13230 * tests/regression.at (braces parsing): New.
13232 2002-01-06 Akim Demaille <akim@epita.fr>
13234 Bison is dead wrong in its RR conflict reports.
13236 * tests/torture.at (GNU Cim Grammar): New.
13237 * src/conflicts.c (count_rr_conflicts): Fix.
13239 2002-01-06 Akim Demaille <akim@epita.fr>
13241 Creating package.m4 from configure.ac causes too many problems.
13243 * tests/Makefile.am (package.m4): Create it by hand,
13244 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
13246 2002-01-06 Akim Demaille <akim@epita.fr>
13248 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
13251 2002-01-04 Paul Eggert <eggert@twinsun.com>
13253 * doc/bison.texinfo (Debugging):
13254 Remove YYSTDERR; it's no longer defined or used.
13255 Also, s/cstdio.h/cstdio/.
13257 2002-01-03 Akim Demaille <akim@epita.fr>
13259 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
13261 2002-01-03 Akim Demaille <akim@epita.fr>
13263 * src/parse-skel.y (process_skeleton): Don't bind the parser's
13264 tracing code to --trace, wait for a better --trace option, with
13267 2002-01-03 Akim Demaille <akim@epita.fr>
13269 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
13270 The ISO C++ standard is extremely clear about it: stderr is
13271 considered a macro, not a regular symbol (see table 94 `Header
13272 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
13273 Therefore std:: does not apply to it. It still does with fprintf.
13274 Also, s/cstdio.h/cstdio/.
13276 2002-01-03 Akim Demaille <akim@epita.fr>
13278 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
13279 for non system headers.
13281 2002-01-02 Akim Demaille <akim@epita.fr>
13283 Equip the skeleton chain with location tracking, runtime trace,
13284 pure parser and scanner.
13286 * src/parse-skel.y: Request a pure parser, locations, and prefix
13288 (%union): Having several members with the same type does not help
13289 type mismatches, simplify.
13290 (YYPRINT, yyprint): New.
13291 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
13292 (skel_error): this.
13294 * src/scan-skel.l: Adjust to these changes.
13295 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
13296 (LOCATION_PRINT, skel_control_t): New.
13298 2001-12-30 Akim Demaille <akim@epita.fr>
13300 * src/parse-skel.y: Get rid of the shift/reduce conflict:
13301 replace `gb' with BLANKS.
13302 * src/scan-skel.l: Adjust.
13304 2001-12-30 Akim Demaille <akim@epita.fr>
13306 * src/system.h: We don't need nor want bcopy.
13307 Throw away MS-DOS crap: we don't need getpid.
13308 * configure.in: We don't need strndup. It was even causing
13309 problems: because Flex includes the headers *before* us,
13310 _GNU_SOURCE is not defined by config.h, and therefore strndup was
13312 * lib/xstrndup.c: New.
13313 * src/scan-skel.l: Use it.
13314 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
13315 * src/parse-skel.y: Use %directives instead of #defines.
13317 2001-12-30 Akim Demaille <akim@epita.fr>
13319 * src/skeleton.h: New.
13320 * src/output.c (output_parser, output_master_parser): Remove, dead
13322 * src/output.h (get_lines_number, actions_output, guards_output)
13323 (token_definitions_output): Prototype them.
13324 * src/parse-skel.y: Add the license notice.
13325 Include output.h and skeleton.h.
13326 (process_skeleton): Returns void, and takes a single parameter.
13327 * src/scan-skel.l: Add the license notice.
13328 Include skeleton.h.
13329 Don't use %option yylineno: it seems that then Flex imagines
13330 REJECT has been used, and therefore it won't reallocate its
13331 buffers (which makes no other sense to me than a bug). It results
13332 in warnings for `unused: yy_flex_realloc'.
13334 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
13336 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
13337 (MUSCLE_INSERT_PREFIX): ...to there.
13338 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
13339 (MUSCLE_INSERT_PREFIX): Move from here...
13341 * src/bison.hairy: Add a section directive. Put braces around muscle
13342 names. This parser skeleton is still broken, but Bison should not
13343 choke on a bad muscle 'syntax'.
13344 * src/bison.simple: Add a section directive. Put braces around muscle
13347 * src/files.h (strsuffix, stringappend): Add declarations.
13348 (tab_extension): Add declaration.
13349 (short_base_name): Add declaration.
13351 * src/files.c (strsuffix, stringappend): No longer static. These
13352 functions are used in the skeleton parser.
13353 (tab_extension): New.
13354 (compute_base_names): Use the computations done in this function
13355 to guess if the generated parsers should have '.tab' in their
13357 (short_base_name): No longer static.
13359 * src/output.c (output_skeleton): New.
13360 (output): Disable call to output_master_parser, and give a try to
13361 a new skeleton handling system.
13362 (guards_output, actions_output): No longer static.
13363 (token_definitions_output, get_lines_number): No longer static.
13365 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
13367 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
13370 * src/parse-skel.y: New file.
13371 * src/scan-skel.l: New file.
13373 2001-12-29 Akim Demaille <akim@epita.fr>
13375 %name-prefix is broken.
13377 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
13378 Adjust all dependencies.
13379 * tests/headers.at (export YYLTYPE): Strengthen this test: use
13382 Renaming yylval but not yylloc is not consistent. Now we do.
13384 * src/bison.simple: Prefix yylloc if used.
13385 * doc/bison.texinfo (Decl Summary): Document that.
13387 2001-12-29 Akim Demaille <akim@epita.fr>
13389 * doc/bison.texinfo: Promote `%long-directive' over
13391 Remove all references to fixed-output-files, yacc is enough.
13393 2001-12-29 Akim Demaille <akim@epita.fr>
13395 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
13396 user prologue. These are defaults.
13397 * tests/actions.at (Mid-rule actions): Make sure the user can
13398 define YYDEBUG and YYERROR_VERBOSE.
13400 2001-12-29 Akim Demaille <akim@epita.fr>
13402 * src/output.c (header_output): Don't forget to export YYLTYPE and
13404 * tests/headers.at (export YYLTYPE): New, make sure it does.
13405 * tests/regression.at (%union and --defines, Invalid CPP headers):
13407 * tests/headers.at: here.
13409 2001-12-29 Akim Demaille <akim@epita.fr>
13411 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
13413 2001-12-29 Akim Demaille <akim@epita.fr>
13415 * tests/actions.at (Mid-rule actions): Output on a single line
13416 instead of several.
13418 2001-12-29 Akim Demaille <akim@epita.fr>
13420 * doc/bison.texinfo: Formatting changes.
13422 2001-12-29 Akim Demaille <akim@epita.fr>
13424 Don't store the token defs in a muscle, just be ready to output it
13425 on command. Now possible via `symbols'. Fixes a memory leak.
13427 * src/output.c (token_definitions_output): New.
13428 (output_parser, header_output): Use it.
13429 * src/reader.c (symbols_save): Remove.
13431 2001-12-29 Akim Demaille <akim@epita.fr>
13433 * src/bison.simple: Do not provide a default for YYSTYPE and
13434 YYLTYPE before the user's prologue. Otherwise it's hardly... a
13437 2001-12-29 Akim Demaille <akim@epita.fr>
13439 Mid-rule actions are simply... ignored!
13441 * src/reader.c (readgram): Be sure to attach mid-rule actions to
13442 the empty-rule associated to the dummy symbol, not to the host
13444 * tests/actions.at (Mid-rule actions): New.
13446 2001-12-29 Akim Demaille <akim@epita.fr>
13450 * src/reader.c (reader): Free grammar.
13452 2001-12-29 Akim Demaille <akim@epita.fr>
13456 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
13457 since it allocates it for each state, although only one is needed.
13458 (allocate_storage): Do it here.
13460 2001-12-29 Akim Demaille <akim@epita.fr>
13462 * src/options.h, src/options.c (create_long_option_table): Rename
13464 (long_option_table_new): this, with a clearer prototype.
13465 (percent_table): Remove, unused,
13466 * src/getargs.c (getargs): Adjust.
13468 2001-12-29 Akim Demaille <akim@epita.fr>
13470 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
13471 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
13474 2001-12-29 Akim Demaille <akim@epita.fr>
13476 * src/lalr.c (build_relations): Rename `states' as `states1'.
13477 Sorry, I don't understand exactly what it is, no better name...
13479 2001-12-29 Akim Demaille <akim@epita.fr>
13481 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
13482 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c

13498 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
13499 Adjust all users to use symbols[i]->prec or ->assoc.
13501 2001-12-29 Akim Demaille <akim@epita.fr>
13503 * src/reader.c, src/reader.h (tags): Remove.
13504 Adjust all users to use symbols[i]->tag.
13506 2001-12-29 Akim Demaille <akim@epita.fr>

13510 * src/reader.c (packsymbols): Fill this table.
13512 * src/conflicts.c (resolve_sr_conflict): Adjust.
13513 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
13515 Use symbols[i]->tag instead of tags[i].
13517 2001-12-29 Akim Demaille <akim@epita.fr>
13519 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
13520 In addition, put a comment in there, to replace...
13521 * tests/regression.at (%union and C comments): Remove.
13523 2001-12-29 Akim Demaille <akim@epita.fr>
13525 * tests/regression.at (Web2c Actions): Blindly move the actual
13526 output as expected output. The contents *seem* right to me, but I
13527 can't pretend reading perfectly parser tables... Nonetheless, all
13528 the other tests pass correctly, the table look OK, even though the
13529 presence of `$axiom' is to be noted: AFAICS it is useless (but
13532 2001-12-29 Akim Demaille <akim@epita.fr>
13534 * src/reader.c (readgram): Don't add the rule 0 if there were no
13535 rules read. In other words, add it _after_ having performed
13536 grammar sanity checks.
13537 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
13539 2001-12-29 Akim Demaille <akim@epita.fr>
13541 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
13542 visible, and some states have now a different number.
13544 2001-12-29 Akim Demaille <akim@epita.fr>
13546 * src/reader.c (readgram): Bind the initial rule's lineno to that
13548 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
13549 (Solved SR Conflicts): Adjust rule 0's line number.
13551 2001-12-29 Akim Demaille <akim@epita.fr>
13553 Fix the `GAWK Grammar' failure.
13555 * src/LR0.c (final_state): Initialize to -1 so that we do compute
13556 the reductions of the first state which was mistakenly confused
13557 with the final state because precisely final_state was initialized
13559 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
13560 now noticed by Bison.
13561 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
13562 have a reduction on $default.
13564 2001-12-29 Akim Demaille <akim@epita.fr>
13566 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
13568 * src/closure.c (print_closure): Likewise.
13569 * src/derives.c (print_derives): Likewise.
13570 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
13573 2001-12-29 Akim Demaille <akim@epita.fr>
13575 * src/lalr.c (lookaheads_print): New.
13576 (lalr): Call it when --trace-flag.
13577 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
13580 2001-12-29 Akim Demaille <akim@epita.fr>
13582 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
13583 when walking through ritem, even via rule->rhs.
13584 * src/reduce.c (dump_grammar, useful_production, reduce_output)
13585 (useful_production, useless_nonterminals): Likewise.
13586 (reduce_grammar_tables): Likewise, plus update nritems.
13587 * src/nullable.c (set_nullable): Likewise.
13588 * src/lalr.c (build_relations): Likewise.
13589 * tests/sets.at (Nullable): Adjust.
13590 Fortunately, now, the $axiom is no longer nullable.
13592 2001-12-29 Akim Demaille <akim@epita.fr>
13594 * src/LR0.c (generate_states): Use nritems, not nitems, nor using

13600 * src/nullable.c (set_nullable): Likewise.
13602 2001-12-29 Akim Demaille <akim@epita.fr>
13604 * src/output.c: Comment changes.
13606 2001-12-27 Paul Eggert <eggert@twinsun.com>
13608 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
13609 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
13610 Sparc, as they were causing more porting problems than the
13611 (minor) performance improvement was worth.
13613 Also, catch up with 1.31's YYSTD.
13615 2001-12-27 Akim Demaille <akim@epita.fr>
13617 * src/output.c (output_gram): Rely on nritems, not the
13618 0-sentinel. See below.
13619 Use -1 as separator, not 0.
13620 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
13621 Rely on -1 as separator in yyrhs, instead of 0.
13622 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
13623 twice `Now at end of input', therefore there are two lines less to
13626 2001-12-27 Akim Demaille <akim@epita.fr>
13628 * tests/regression.at (Unresolved SR Conflicts):
13629 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
13632 2001-12-27 Akim Demaille <akim@epita.fr>
13634 * src/LR0.c (new_state): Recognize the final state by the fact it
13635 is reached by eoftoken.
13636 (insert_start_shifting_state, insert_eof_shifting_state)
13637 (insert_accepting_state, augment_automaton): Remove, since now
13638 these states are automatically computed from the initial state.
13639 (generate_states): Adjust.
13640 * src/print.c: When reporting a rule number to the user, substract
13641 1, so that the axiom rule is rule 0, and the first user rule is 1.
13642 * src/reduce.c: Likewise.
13643 * src/print_graph.c (print_core): For the time being, just as for
13644 the report, depend upon --trace-flags to dump the full set of
13646 * src/reader.c (readgram): Once the grammar read, insert the rule
13647 0: `$axiom: START-SYMBOL $'.
13648 * tests/set.at: Adjust: rule 0 is now displayed, and since the
13649 number of the states has changed (the final state is no longer
13650 necessarily the last), catch up.
13652 2001-12-27 Akim Demaille <akim@epita.fr>
13654 Try to make the use of the eoftoken valid. Given that its value
13655 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
13656 is used instead of > 0 where appropriate, (ii), depend upon nritems
13657 instead of the 0-sentinel.
13659 * src/gram.h, src/gram.c (nritems): New.
13660 Expected to be duplication of nitems, but for the time being...
13661 * src/reader.c (packgram): Assert nritems and nitems are equal.
13662 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
13663 * src/closure.c (print_closure, print_fderives): Likewise.

13668 2001-12-27 Akim Demaille <akim@epita.fr>
13670 * src/main.c (main): If there are complains after grammar
13671 reductions, then output the report anyway if requested, then die.
13672 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
13673 * src/reader.c (eoftoken): New.
13674 (parse_token_decl): If the token being defined has value `0', it
13676 (packsymbols): No longer hack `tags' to insert `$' by hand.
13677 Be sure to preserve the value of the eoftoken.
13678 (reader): Make sure eoftoken is defined.
13679 Initialize nsyms to 0: now eoftoken is created just like the others.
13680 * src/print.c (print_grammar): Don't special case the eof token.
13681 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
13682 lie anyway, albeit pleasant.
13683 * tests/calc.at: Exercise error messages with eoftoken.
13684 Change the grammar so that empty input is invalid.
13685 Adjust expectations.
13686 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
13688 2001-12-27 Akim Demaille <akim@epita.fr>
13690 * configure.in: Check the protos of strchr ans strspn.
13691 Replace strchr if needed.
13692 * src/system.h: Provide the protos of strchr, strspn and memchr if
13694 * lib/strchr.c: New.
13695 * src/reader.c (symbols_save): Use strchr.
13697 2001-12-27 Akim Demaille <akim@epita.fr>
13699 * src/print.c, src/print_graph.c (escape): New.
13700 Use it to quote the TAGS outputs.
13701 * src/print_graph.c (print_state): Now errors are in red, and
13702 reductions in green.
13703 Prefer high to wide: output the state number on a line of its own.
13705 2001-12-27 Akim Demaille <akim@epita.fr>
13707 * src/state.h, src/state.c (reductions_new): New.
13708 * src/LR0.c (set_state_table): Let all the states have a
13709 `reductions', even if reduced to 0.

13728 2001-12-27 Akim Demaille <akim@epita.fr>
13730 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
13731 * src/print.c: here.
13732 (lookaheadset, shiftset): New, used as additional storage by
13734 (print_results): Adjust.
13735 (print_shifts, print_gotos, print_errs): New, extracted from...
13736 (print_actions): here.
13737 * src/print_graph.c (print_actions): Remove dead code.
13739 2001-12-27 Akim Demaille <akim@epita.fr>

13744 2001-12-27 Akim Demaille <akim@epita.fr>
13746 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
13747 (build_relations): Adjust.

13761 * src/output.c (output): Adjust.
13762 * src/reader.c (parse_braces): New, factoring...
13763 (copy_action, copy_guard): these two which are renamed as...
13764 (parse_action, parse_guard): these.
13765 As a voluntary consequence, using braces around guards is now
13768 2001-12-27 Akim Demaille <akim@epita.fr>
13770 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
13771 * src/reader.c (symbol_list): `guard' and `guard_line' are new
13773 (symbol_list_new): Adjust.
13774 (copy_action): action_line is the first line, not the last.
13775 (copy_guard): Just as for actions, store the `action' only, not
13776 the switch/case/break flesh.
13777 Don't parse the user action that might follow the guard, let...
13778 (readgram): do it, i.e., now, there can be an action after a
13780 In other words the guard is just explicitly optional.
13781 (packgram): Adjust.
13782 * src/output.c (guards_output): New.
13783 (output_parser): Call it when needed.
13784 (output): Also free the guard and attrs obstacks.
13785 * src/files.c, src/files.h (obstack_save): Remove.
13786 (output_files): Remove.
13787 As a result, if one needs the former `.act' file, using an
13788 appropriate skeleton which requires actions and guards is now
13790 * src/main.c (main): Adjust.
13791 * tests/semantic.at: New.
13792 * tests/regression.at: Use `input.y' as input file name.
13793 Avoid 8+3 problems by requiring input.c when the test needs the

13798 * src/reader.c (symbol_list_new): Be sure to initialize all the
13801 2001-12-27 Akim Demaille <akim@epita.fr>
13803 All the hacks using a final pseudo state are now useless.
13805 * src/LR0.c (set_state_table): state_table holds exactly nstates.
13806 * src/lalr.c (nLA): New.
13807 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
13808 instead of lookaheadsp from the pseudo state (nstate + 1).
13810 2001-12-27 Akim Demaille <akim@epita.fr>
13812 * src/output.c (action_row, token_actions): Use a state_t instead
13813 of a integer, and nlookaheads instead of the following state's

13820 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
13821 (conflicts_print, print_reductions): Use a state_t instead of an
13822 integer when referring to a state.
13823 As much as possible, depend upon nlookaheads, instead of the
13824 `lookaheadsp' member of the following state (since lookaheads of
13825 successive states are successive, the difference between state n + 1
13826 and n served as the number of lookaheads for state n).
13827 * src/lalr.c (add_lookback_edge): Likewise.
13828 * src/print.c (print_core, print_actions, print_state)
13829 (print_results): Likewise.

13839 Add plenty of `static'.
13841 2001-12-27 Akim Demaille <akim@epita.fr>
13843 * src/output.c (prepare): Drop the muscle `ntbase' which
13844 duplicates ntokens.
13845 * src/bison.simple: Formatting/comment changes.
13846 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
13847 is an undocumented synonym.
13849 2001-12-22 Akim Demaille <akim@epita.fr>
13851 * src/output.c (output_table_data): Change the prototype to use
13852 `int' for array ranges: some invocations do pass an int, not a
13854 Reported by Wayne Green.
13856 2001-12-22 Akim Demaille <akim@epita.fr>
13858 Some actions of web2c.y are improperly triggered.

13874 2001-12-18 Akim Demaille <akim@epita.fr>
13876 Some host fail on `assert (!"foo")', which expands to
13877 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
13878 Reported by Nelson Beebee.
13880 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
13881 `#define it_succeeded 0' and `assert (it_succeeded)'.
13883 2001-12-17 Marc Autret <autret_m@epita.fr>
13885 * src/bison.simple: Don't hard code the skeleton line and filename.
13886 * src/output.c (output_parser): Rename 'line' as 'output_line'.
13887 New line counter 'skeleton_line' (skeleton-line muscle).
13889 2001-12-17 Paul Eggert <eggert@twinsun.com>
13891 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
13892 YYDEBUG must be defined to a nonzero value.
13894 * src/bison.simple (yytname): Do not assume that the user defines
13895 YYDEBUG to a properly parenthesized expression.
13897 2001-12-17 Akim Demaille <akim@epita.fr>
13899 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
13900 nlookaheads is a new member.
13902 * src/lalr.h (nlookaheads): Remove this orphan declaration.
13903 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each

13908 * src/files.h, src/files.c (open_files, close_files): Remove.
13909 * src/main.c (main): Don't open/close files, nor invoke lex_free,
13911 * src/reader.c (reader): Do it.
13913 2001-12-17 Akim Demaille <akim@epita.fr>
13915 * src/conflicts.c (print_reductions): Formatting changes.
13917 2001-12-17 Akim Demaille <akim@epita.fr>

13928 * src/reader.h (muscle_obstack): Move to...

13931 2001-12-17 Akim Demaille <akim@epita.fr>
13933 * src/output.c (action_row, save_column, default_goto)

13949 2001-12-16 Marc Autret <autret_m@epita.fr>
13951 * src/output.c (actions_output): Fix. When we use %no-lines,
13952 there is one less line per action.
13954 2001-12-16 Marc Autret <autret_m@epita.fr>
13956 * src/bison.simple: Remove a useless #line directive.
13957 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
13958 * src/output.c (get_lines_number): New.
13959 (output_parser): Adjust, now takes care about the lines of a
13961 Fix line numbering.
13962 (actions_output): Computes the number of lines taken by actions.
13963 (output_master_parser): Insert new skeleton which is the name of
13964 the output parser file name.
13966 2001-12-15 Marc Autret <autret_m@epita.fr>
13968 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
13970 2001-12-15 Marc Autret <autret_m@epita.fr>
13972 * src/output.c (output_gram): Keep track of the hairy one.
13974 2001-12-15 Akim Demaille <akim@epita.fr>
13976 Make `make distcheck' work.
13978 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
13979 system.h which uses libgettext.h.
13981 2001-12-15 Akim Demaille <akim@epita.fr>
13983 * src/nullable.c (set_nullable): Useless rules must be skipped,
13984 otherwise, since we range over their symbols, we might look at a
13985 nonterminal which no longer ``exists'', i.e., it is not counted in
13986 `nvars', hence we overflow our arrays.
13988 2001-12-15 Akim Demaille <akim@epita.fr>
13990 The header can also be produced directly, without any obstack!
13993 * src/files.c, src/files.h (defines_obstack): Remove.
13994 (compute_header_macro): Global.
13995 (defines_obstack_save): Remove.
13996 * src/reader.c (parse_union_decl): No longer output to
13997 defines_obstack: its content can be found in the `stype' muscle
13999 (output_token_translations): Merge into...
14000 (symbols_output): this.
14002 (symbols_save): this.
14004 * src/output.c (header_output): New.
14007 2001-12-15 Akim Demaille <akim@epita.fr>
14009 * src/reader.c (parse_union_decl): Instead of handling two obstack
14010 simultaneously, use one to define the `stype' muscle, and use the
14011 value of the latter to fill defines_obstack.
14012 (copy_comment): Remove.
14013 (copy_comment2): Work for a single obstack.
14015 (copy_comment): this.
14017 2001-12-15 Akim Demaille <akim@epita.fr>
14019 * src/lex.c, src/lex.h (xgetc): No longer static.
14020 * src/reader.c (parse_union_decl): Revamp.
14022 2001-12-15 Akim Demaille <akim@epita.fr>
14024 Still making progress in separating Bison into (i) input, (ii)
14025 process, (iii) output: now we can directly output the parser file
14026 without using table_obstack at all.
14028 * src/files.c, src/files.h (table_obstack): Bye bye.
14029 (parser_file_name): New.
14030 * src/files.c (compute_output_file_names): Compute it.
14031 * src/output.c (actions_output, output_parser)
14032 (output_master_parser): To a file instead of an obstack.
14034 2001-12-15 Akim Demaille <akim@epita.fr>
14036 Attach actions to rules, instead of pre-outputting them to
14039 * src/gram.h (rule_t): action and action_line are new members.
14040 * src/reader.c (symbol_list): Likewise.
14041 (copy_action): Save the actions within the rule.
14042 (packgram): Save them in rule_table.
14043 * src/output.c (actions_output): New.
14044 (output_parser): Use it on `%%actions'.
14045 (output_rule_data): Don't free rule_table.
14047 (prepare): Don't save the `action' muscle.
14048 * src/bison.simple: s/%%action/%%actions/.
14050 2001-12-15 Akim Demaille <akim@epita.fr>
14052 * src/reader.c (copy_action): When --yacc, don't append a `;'
14053 to the user action: let it fail if lacking.
14054 Suggested by Arnold Robbins and Tom Tromey.
14056 2001-12-14 Akim Demaille <akim@epita.fr>
14058 * src/lex.c (literalchar): Simply return the char you decoded, non
14059 longer mess around with obstacks and int pointers.
14060 Adjust all callers.
14062 2001-12-14 Akim Demaille <akim@epita.fr>
14064 * src/lex.c (literalchar): Don't escape the special characters,
14065 just decode them, and keep them as char (before, eol was output as
14066 the 2 char string `\n' etc.).
14067 * src/output.c (output_rule_data): Use quotearg to output the
14070 2001-12-13 Paul Eggert <eggert@twinsun.com>
14072 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
14073 Do not infringe on the global user namespace when using C++.
14074 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
14075 All uses of `fprintf' and `stderr' changed.
14077 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
14079 2001-12-13 Akim Demaille <akim@epita.fr>
14081 The computation of nullable is broken: it doesn't handle empty
14084 * tests/torture.at (GNU AWK Grammar): New.
14085 * tests/sets.at (Nullable): New.
14086 * src/nullable.c (set_nullable): Instead of blindly looping over
14087 `ritems', loop over the rules, and then over their rhs's.
14089 Work around Autotest bugs.
14091 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
14092 frame, because Autotest understand lines starting with a `+' as
14093 traces from the shell. Then, they are not processed properly.
14094 Admittedly an Autotest bug, but we don't have time to wait for
14095 Autotest to catch up.
14096 * tests/regression.at (Broken Closure): Adjust to the new table
14099 * tests/sets.at: here.
14101 2001-12-13 Akim Demaille <akim@epita.fr>
14103 * src/closure.c (closure): Use nrules instead of playing tricks
14104 with BITS_PER_WORD.
14106 2001-12-13 Akim Demaille <akim@epita.fr>
14108 * src/print.c (print_actions): Output the handling of `$' as the
14109 traces do: shifting the token EOF. Before EOF was treated as a
14111 * tests/regression.at: Adjust some tests.
14112 * src/print_graph.c (print_core): Complete the set of items via
14113 closure. The next-to-final and final states are still unsatisfying,
14114 but that's to be addressed elsewhere.
14115 No longer output the rule numbers, but do output the state number.
14116 A single loop for the shifts + gotos is enough, but picked a
14117 distinct color for each.
14118 (print_graph): Initialize and finalize closure.
14120 2001-12-13 Akim Demaille <akim@epita.fr>
14122 * src/reader.c (readgram): Remove dead code, an strip useless
14124 (get_type): Remove, unused.
14126 2001-12-12 Akim Demaille <akim@epita.fr>
14128 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
14129 on that of lib/error.c.
14131 2001-12-12 Akim Demaille <akim@epita.fr>
14133 Some hosts don't like `/' in includes.
14135 * src/system.h: Include libgettext.h without qualifying the path.
14136 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
14139 2001-12-11 Marc Autret <autret_m@epita.fr>
14141 * src/output.c (output_parser): Remove useless muscle.
14143 2001-12-11 Marc Autret <autret_m@epita.fr>
14145 * src/bison.simple: Remove #line just before %%epilogue. It
14146 is now handled in ...
14147 * src/reader.c (read_additionnal_code): Add the output of a
14148 #line for the epilogue.
14150 2001-12-10 Marc Autret <autret_m@epita.fr>
14152 * src/reader.c (copy_definition): Re-use CPP-outed code which
14153 replace precedent remove.
14154 * src/bison.simple: Remove #line before %%prologue because
14155 %%input-line is wrong at this time.
14157 2001-12-10 Marc Autret <autret_m@epita.fr>
14159 * src/reader.c (symbols_output): Clean up.
14160 * src/output.c (output_gram, output): Clean up.
14162 2001-12-10 Akim Demaille <akim@epita.fr>
14164 * src/lalr.c (initialize_lookaheads): New. Extracted from...
14165 * src/LR0.c (set_state_table): here.
14166 * src/lalr.c (lalr): Call it.
14168 2001-12-10 Akim Demaille <akim@epita.fr>
14170 * src/state.h (shifts): Remove the `number' member: shifts are
14171 attached to state, hence no longer need to be labelled with a
14174 2001-12-10 Akim Demaille <akim@epita.fr>
14176 Now that states have a complete set of members, the linked list of
14177 shifts is useless: just fill directly the state's shifts member.
14179 * src/state.h (shifts): Remove the `next' member.
14180 * src/LR0.c (first_state, last_state): Remove.
14181 Adjust the callers.
14182 (augment_automaton): Don't look for the shifts that must be added
14183 a shift on EOF: it is those of the state we looked for! But now,
14184 since shifts are attached, it is no longer needed to looking
14185 merely by its id: its number.
14187 2001-12-10 Akim Demaille <akim@epita.fr>
14189 * src/LR0.c (augment_automaton): Better variable locality.
14190 Remove an impossible branch: if there is a state corresponding to
14191 the start symbol being shifted, then there is shift for the start
14192 symbol from the initial state.
14194 2001-12-10 Akim Demaille <akim@epita.fr>
14196 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
14197 only when appropriate: when insert_start_shifting_state' is not
14199 * tests/regression.at (Rule Line Numbers): Adjust.
14201 2001-12-10 Akim Demaille <akim@epita.fr>
14203 * src/LR0.c (augment_automaton): Now that all states have shifts,
14204 merge the two cases addition shifts to the initial state.
14206 2001-12-10 Akim Demaille <akim@epita.fr>
14208 * src/lalr.c (set_state_table): Move to...
14210 * src/lalr.c (lalr): Don't call it...
14211 * src/LR0.c (generate_states): do it.
14212 * src/LR0.h (first_state): Remove, only the table is used.
14214 2001-12-10 Akim Demaille <akim@epita.fr>
14216 * src/LR0.h (first_shift, first_reduction): Remove.
14217 * src/lalr.c: Don't use first_shift: find shifts through the
14220 2001-12-10 Akim Demaille <akim@epita.fr>
14222 * src/LR0.c: Attach shifts to states as soon as they are
14224 * src/lalr.c (set_state_table): Instead of assigning shifts to
14225 state, just assert that the mapping was properly done.
14227 2001-12-10 Akim Demaille <akim@epita.fr>
14229 * src/LR0.c (insert_start_shift): Rename as...
14230 (insert_start_shifting_state): this.
14231 (insert_eof_shifting_state, insert_accepting_state): New.
14232 (augment_automaton): Adjust.
14233 Better locality of the variables.
14234 When looking if the start_symbol is shifted from the initial
14235 state, using `while (... symbol != start_symbol ...)' sounds
14236 better than `while (... symbol < start_symbol ...)': If fail
14237 to see how the order between symbols could be relevant!
14239 2001-12-10 Akim Demaille <akim@epita.fr>
14241 * src/getargs.h: Don't declare `spec_name_prefix' and
14242 `spec_file_prefix', declared by src/files.h.
14243 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
14244 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
14245 * src/output.c (prepare): Adjust.
14246 * src/reader.c (symbols_output): Likewise.
14247 * src/vmsgetargs.c: Vaguely adjust, but who cares?
14249 2001-12-10 Akim Demaille <akim@epita.fr>
14251 * src/muscle_tab.c (muscle_init): NULL is a better default than
14254 2001-12-10 Akim Demaille <akim@epita.fr>
14256 * src/reader.c (reader): Calling symbols_output once is enough.
14258 2001-12-10 Akim Demaille <akim@epita.fr>
14260 Now that states have a complete set of members, the linked list of
14261 reductions is useless: just fill directly the state's reductions
14264 * src/state.h (struct reductions): Remove member `number' and
14266 * src/LR0.c (first_reduction, last_reduction): Remove.
14267 (save_reductions): Don't link the new reductions, store them in
14269 * src/lalr.c (set_state_table): No need to attach reductions to
14270 states, it's already done.
14271 * src/output.c (output_actions): No longer free the shifts, then
14272 the reductions, then the states: free all the states and their
14275 2001-12-10 Akim Demaille <akim@epita.fr>
14277 * src/options.c (OPTN, DRTV, BOTH): New.
14278 (option_table): Use them.
14280 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
14281 the job of system.h.
14282 * src/options.c: Don't include stdio.h and xalloc.h for the same
14285 2001-12-10 Akim Demaille <akim@epita.fr>
14287 * src/output.c (output, prepare): Make sure the values of the
14288 muscles `action' and `prologue' are 0-terminated.
14290 2001-12-10 Akim Demaille <akim@epita.fr>
14292 Clean up GCC warnings.
14294 * src/reader.c (copy_action): `buf' is not used.
14295 (parse_skel_decl): Be static.
14296 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
14297 * src/options.h (create_long_option_table): Have a real prototype.
14298 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
14299 (hash_delete_at): Return const void *.
14300 Adjust casts to preserve the const.
14302 2001-12-10 Akim Demaille <akim@epita.fr>
14304 * configure.in: Require 2.52g.
14305 M4 is not needed, but AUTOM4TE is.
14306 * m4/m4.m4: Remove.
14307 * tests/Makefile.am: Adjust.
14309 2001-12-10 Akim Demaille <akim@epita.fr>
14311 One structure for states is enough, even though theoretically
14312 there are LR(0) states and LALR(1) states.
14314 * src/lalr.h (state_t): Remove.
14315 (state_table): Be state_t **, not state_t *.
14316 * src/state.h (core, CORE_ALLOC): Rename as...
14317 (state_t, STATE_ALLOC): this.
14318 Add the LALR(1) members: shifts, reductions, errs.
14319 * src/LR0.c (state_table): Rename as...
14320 (state_hash): this, to avoid name clashes with the global
14322 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
14323 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
14325 2001-12-10 Akim Demaille <akim@epita.fr>
14327 Bison dumps core on bash.y.
14328 Reported by Pascal Bart.
14330 * src/warshall.c (bitmatrix_print): New.
14332 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
14333 j must be the outer loop.
14334 * tests/regression.at (Broken Closure): New.
14336 2001-12-05 Akim Demaille <akim@epita.fr>
14338 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
14340 Reported by Peter Hamorsky.
14342 2001-12-05 Akim Demaille <akim@epita.fr>
14344 * src/conflicts.c (err_table): Remove.
14345 (resolve_sr_conflict): Adjust.
14346 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
14348 (state_t.reductions, state_t.shifts): this.
14350 2001-12-05 Akim Demaille <akim@epita.fr>
14352 * src/reduce.c (reduce_grammar_tables): No longer disable the
14353 removal of useless rules via CPP but via `if (0)', so that the
14354 compiler still check the code is valid.
14355 For instance, it should have noticed `rline' no longer exists: use
14356 the `line' member of rule_t.
14357 * src/gram.c (dummy, rline): Remove, unused.
14359 2001-12-05 Akim Demaille <akim@epita.fr>
14361 * src/output.c (pack_vector): Use assert, not berror.
14362 * src/main.c (berror): Remove, unused.
14364 2001-12-05 Akim Demaille <akim@epita.fr>
14366 New experimental feature: if --verbose --trace output all the
14367 items of a state, not only its kernel.
14369 * src/print.c (print_core): If `trace_flag', then invoke closure
14370 before outputting the items of the state (print_core is no longer
14371 a correct name them).
14372 (print_results): Invoke new_closure/free_closure if needed.
14374 2001-12-05 Akim Demaille <akim@epita.fr>
14376 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
14377 * src/closure.c, src/closure.h (itemsetsize): Rename as...
14378 (nitemset): for consistency with the rest of the project.
14380 2001-12-05 Akim Demaille <akim@epita.fr>
14382 * src/closure.c (print_closure): Improve.
14383 (closure): Use it for printing input and output.
14385 2001-12-05 Akim Demaille <akim@epita.fr>
14387 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
14388 indexed by nonterminals.
14390 2001-12-05 Akim Demaille <akim@epita.fr>
14392 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
14394 * src/warshall.h: Remove accidental duplication of the content.
14396 2001-12-05 Akim Demaille <akim@epita.fr>

14408 2001-12-05 Akim Demaille <akim@epita.fr>
14410 * src/output.c (action_row): De-obfuscate
14411 using the good o' techniques: arrays not pointers, variable
14412 locality, BITISSET, RESETBIT etc.
14414 2001-12-05 Akim Demaille <akim@epita.fr>
14416 Pessimize the code to simplify it: from now on, all the states
14417 have a valid SHIFTS, which NSHIFTS is possibly 0.
14419 * src/LR0.c (shifts_new): Be global and move to..
14420 * src/state.c, src/state.h: here.
14421 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
14422 * src/print_graph: Adjust.
14424 2001-12-05 Akim Demaille <akim@epita.fr>
14426 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
14427 * src/conflicts.c: Use it.
14428 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
14429 incorrectly ``simplified''.
14431 2001-12-05 Akim Demaille <akim@epita.fr>
14433 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
14434 using the good o' techniques: arrays not pointers, variable
14435 locality, BITISSET, RESETBIT etc.
14437 2001-12-05 Akim Demaille <akim@epita.fr>
14439 * src/state.h (SHIFT_SYMBOL): New.
14440 * src/conflicts.c: Use it to deobfuscate.
14442 2001-12-05 Akim Demaille <akim@epita.fr>
14444 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
14445 (print_reductions): De-obfuscate using the good o' techniques:
14446 arrays not pointers, variable locality, BITISSET.
14448 2001-12-05 Akim Demaille <akim@epita.fr>
14450 * src/conflicts.c (print_reductions): Arrays, not pointers.
14453 2001-12-05 Akim Demaille <akim@epita.fr>
14455 * src/conflicts.c (print_reductions): Pessimize, but clarify.
14457 2001-12-05 Akim Demaille <akim@epita.fr>
14459 * src/conflicts.c (print_reductions): Improve variable locality.
14461 2001-12-05 Akim Demaille <akim@epita.fr>

14485 2001-12-05 Akim Demaille <akim@epita.fr>
14487 * src/lalr.c (maxrhs): Move to...
14488 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
14489 * src/lalr.c (build_relations): Adjust.
14491 2001-12-05 Akim Demaille <akim@epita.fr>
14493 * src/lalr.c (transpose): Free the memory allocated to the
14494 argument, as it is replaced by the results by the unique caller.
14495 (build_relations): Merely invoke transpose: it handles the memory
14497 Improve variable locality.
14498 Avoid variables used as mere abbreviations.
14499 (compute_lookaheads): Use arrays instead of pointers.
14501 2001-12-05 Akim Demaille <akim@epita.fr>
14503 * src/lalr.c (initialize_F): Improve variable locality.

14519 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
14520 the handling of squeue.
14521 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
14523 2001-12-05 Akim Demaille <akim@epita.fr>
14525 Because useless nonterminals are now kept alive (instead of being
14526 `destroyed'), we now sometimes examine them, and store information
14527 related to them. Hence we need to know their number, and adjust
14528 memory allocations.
14530 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
14532 * src/LR0.c (allocate_itemsets): The memory allocated to
14533 `symbol_count' was used for two different purpose: once to count
14534 the number of occurrences of each symbol, and later reassigned to
14535 `shift_symbol', containing the symbol that can be shifted from a
14537 Deobfuscate, i.e., allocate, use and free `symbol_count' here
14539 (new_itemsets): Allocate `shift_symbol' here.
14540 (allocate_itemsets): symbol_count includes useless nonterminals.
14541 Make room for them.
14542 (free_storage): Use `free', not `XFREE', for pointers that cannot
14545 2001-12-05 Akim Demaille <akim@epita.fr>

14553 * src/gram.c, src/gram.h (ritem_print): New.
14554 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
14555 (This useless function was defined only to work around VMS linkers
14556 that can't handle compilation units with variables only).
14557 * src/reduce.c (dump_grammar): Use it to trace the construction of
14560 2001-12-04 Paul Eggert <eggert@twinsun.com>
14562 * src/bison.simple (union yyalloc): Change member names
14563 to be the same as the stack names.
14564 (yyparse): yyptr is now union yyalloc *, not char *.
14565 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
14566 and may generate better code on some machines.
14567 (yystpcpy): Use prototype if __STDC__ is defined, not just
14568 if __cplusplus is defined.
14570 2001-11-30 Akim Demaille <akim@epita.fr>
14572 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
14573 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
14574 Gettext doesn't compile cleanly, and dies with -Werror.
14575 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
14576 Include WARNING_CFLAGS here.
14577 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
14578 before being defined.

14582 * lib/quotearg.h (quotearg_n, quotearg_n_style):
14583 First arg is int, not unsigned.
14584 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
14585 (SIZE_MAX, UINT_MAX): New macros.
14586 (quotearg_n_options): Abort if N is negative.
14587 Avoid overflow check on hosts where size_t is 64 bits and int
14588 is 32 bits, as overflow is impossible there.
14589 Fix off-by-one typo that caused unnecessary reallocation.
14591 2001-11-29 Paul Eggert <eggert@twinsun.com>
14593 Name space cleanup in generated parser.
14595 * doc/bison.texinfo (Bison Parser): Discuss system headers
14596 and their effect on the user name space.
14598 * src/bison.simple:
14599 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
14600 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
14601 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
14603 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
14604 on user names when possible.
14606 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
14607 Simplify test for whather <alloca.h> exists.
14609 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
14611 (<stdio.h>): Include if YYDEBUG.
14613 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
14614 ! defined (yyoverflow) && ! defined (yymemcpy).
14616 (yymemcpy, yyparse): Rename local variables as needed so that
14617 they all begin with 'yy'.
14619 (yystrlen, yystpcpy): New functions.
14621 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
14624 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
14625 instead of relying on string.h functions. Use YYSTACK_ALLOC
14626 and YYSTACK_FREE instead of malloc and free.
14628 2001-11-30 Akim Demaille <akim@epita.fr>
14630 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
14631 before their first uses.

14641 if body instead of `;' to pacify GCC's warnings.
14643 2001-11-30 Akim Demaille <akim@epita.fr>
14645 Instead of mapping the LHS of unused rules to -1, keep the LHS
14646 valid, but flag the rules as invalid.
14648 * src/gram.h (rule_t): `useful' is a new member.
14649 * src/print.c (print_grammar): Adjust.
14650 * src/derives.c (set_derives): Likewise.
14651 * src/reader.c (packgram, reduce_output): Likewise.
14652 * src/reduce.c (reduce_grammar_tables): Likewise.

14669 2001-11-30 Akim Demaille <akim@epita.fr>

14679 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
14680 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
14682 (union yyalloc): New type.
14683 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
14684 an arbitrary restriction on hosts where size_t is wider than int.
14686 (yyparse): Don't dump core if alloca or malloc fails; instead, report
14687 a parser stack overflow. Allocate just one block of memory for all
14688 three stacks, instead of allocating three blocks; this typically is
14689 faster and reduces fragmentation.
14691 Do not limit the number of items in the stack to a value that fits
14692 in 'int', as this is an arbitrary limit on hosts with 64-bit
14693 size_t and 32-bit int.
14695 2001-11-29 Marc Autret <autret_m@epita.fr>
14697 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
14698 of defining YYERROR_VERBOSE.
14699 [AT_DATA]: $4 is now out of C declarations in the prologue.
14701 2001-11-28 Marc Autret <autret_m@epita.fr>

14748 2001-11-28 Akim Demaille <akim@epita.fr>
14750 * src/closure.c (closure): Instead of looping over word in array
14751 then bits in words, loop over bits in array.
14753 2001-11-28 Akim Demaille <akim@epita.fr>
14755 * src/closure.c (closure): No longer optimize the special case
14756 where all the bits of `ruleset[r]' are set to 0, to make the code

14868 conflicts as expected.
14869 * tests/regression.at (%expect right): Adjust.
14871 2001-11-23 Akim Demaille <akim@epita.fr>

16538 * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
16539 * src/lex.c (maxtoken, grow_token_buffer): Static.
16541 2001-01-18 Akim Demaille <akim@epita.fr>
16543 Since we now use obstacks, more % directives can be enabled.
16545 * src/lex.c (percent_table): Also accept `%yacc',
16546 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
16548 Handle the actions for `%semantic_parser' and `%pure_parser' here,

16551 * src/reader.c (read_declarations): Adjust.
16552 * src/files.c (open_files): Don't call `compute_base_names', don't

16556 * src/output.c (output_headers): Document the fact that this patch
16557 introduces a guaranteed SEGV for semantic parsers.

16568 * src/conflicts.c: Return a string.
16569 * src/system.h (obstack_grow_string): Rename as...
16570 (obstack_sgrow): this. Be ready to work with non literals.
16571 (obstack_fgrow4): New.
16573 2000-12-20 Akim Demaille <akim@epita.fr>
16575 * src/files.c (open_files): Fix the computation of short_base_name

16626 (obstack_grow_string): this.
16627 * src/output.c (output_parser): Recognize `%% actions' instead of

16659 2000-12-19 Akim Demaille <akim@epita.fr>
16661 * src/files.c (open_files): Yipee! We no longer need all the code
16662 looking for `/tmp' since we have no tmp file.
16664 2000-12-19 Akim Demaille <akim@epita.fr>
16666 * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

16673 Provide a default definition.

16691 2000-11-17 Akim Demaille <akim@epita.fr>
16693 * lib/obstack.h: Formatting changes.
16694 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
16695 prevents type checking.
16696 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
16697 cast the value to (void *): assigning a `foo *' to a `void *'

16719 Use them to declare the variables which are global or local to
16722 2000-11-17 Akim Demaille <akim@epita.fr>
16724 * acconfig.h: Remove, no longer used.
16726 2000-11-07 Akim Demaille <akim@epita.fr>
16728 * src: s/Copyright (C)/Copyright/g.
16730 2000-11-07 Akim Demaille <akim@epita.fr>
16732 * src/reader.c (reader): #define YYLSP_NEEDED to 1 instead of just
16734 * src/bison.s1: s/#ifdef YYLSP_NEEDED/#if YYLSP_NEEDED/.
16736 2000-11-07 Akim Demaille <akim@epita.fr>
16738 * src/bison.s1 (YYLEX): Use #if instead of #ifdef.

16747 (obstack_copy, obstack_copy0): Rename the second argument as
16748 `address' for consistency. Qualify it `const'.
16749 * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
16750 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
16751 `const' their input argument (`data' or `address').
16752 Adjust the corresponding macros to include `const' in casts.
16754 2000-11-03 Akim Demaille <akim@epita.fr>
16756 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.
16757 s/PFILE1/BISON_HAIRY/.
16758 Adjust dependencies.
16760 2000-11-03 Akim Demaille <akim@epita.fr>
16762 For some reason, this was not applied.
16764 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
16765 `unlink': it's no longer used.
16767 2000-11-03 Akim Demaille <akim@epita.fr>
16769 * src/files.c (skeleton_find): New function, eved out of...

16774 Don't use `atexit'.
16776 * src/files.c (obstack_save): New function.
16777 (done): Rename as...
16778 (output_files): this.
16779 Use `obstack_save'.
16780 * src/main.c (main): Don't use `atexit' to register `done', since
16781 it no longer has to remove tmp files, just call `output_files'
16782 when there are no errors.
16784 2000-11-02 Akim Demaille <akim@epita.fr>
16786 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
16787 `unlink': it's no longer used.
16788 * src/files.h: Formatting changes.
16790 2000-11-02 Akim Demaille <akim@epita.fr>
16792 Remove the last uses of mktemp and unlink/delete.
16794 * src/files.c (fdefines, ftable): Removed.
16795 (defines_ostack, table_obstack): New.
16796 Adjust dependencies of the former into uses of the latter.

16817 Introduce obstacks.
16818 Change each use of `faction' into a use of `action_obstack'.
16820 * lib/obstack.h, lib/obstack.c: New files.
16821 * src/files.c (faction): Remove.
16822 (action_obstack): New.
16823 Adjust all dependencies.
16825 2000-10-20 Akim Demaille <akim@epita.fr>
16827 * lib/quote.h (PARAMS): New macro. Use it.
16829 2000-10-16 Akim Demaille <akim@epita.fr>
16831 * src/output.c (output_short_or_char_table): New function.
16832 (output_short_table, output_token_translations): Use it.

16846 2000-10-16 Akim Demaille <akim@epita.fr>
16848 * src/lex.c (read_typename): New function.
16850 * src/reader.c (copy_dollar): Likewise.
16852 2000-10-16 Akim Demaille <akim@epita.fr>
16854 * src/reader.c (copy_comment2): Expect the input stream to be on
16855 the `/' which is suspected to open a comment, instead of being
16856 called after `//' or `/*' was read.
16857 (copy_comment, copy_definition, parse_union_decl, copy_action)
16858 (copy_guard): Adjust.
16860 2000-10-16 Akim Demaille <akim@epita.fr>
16862 * src/reader.c (parse_expect_decl): Use `skip_white_space' and
16863 `read_signed_integer'.
16865 2000-10-16 Akim Demaille <akim@epita.fr>
16867 * src/reader.c (copy_dollar): New function.
16868 (copy_guard, copy_action): Use it.
16870 2000-10-16 Akim Demaille <akim@epita.fr>
16872 * lib/quote.h, lib/quote.c, lib/quotearg.h, lib/quotearg.c:
16873 * m4/prereq.m4, m4/c-bs-a.m4, m4/mbstate.m4:
16874 New files, from Fileutils 4.0.27.
16875 * src/main.c (printable_version): Remove.
16876 * src/lex.c, src/reader.c: Use `quote'.
16878 2000-10-04 Akim Demaille <akim@epita.fr>

16882 2000-10-04 Akim Demaille <akim@epita.fr>
16884 * doc/bison.texinfo: Various typos spotted by Neil Booth.
16886 2000-10-04 Akim Demaille <akim@epita.fr>
16888 When a literal string is used to define two different tokens,
16889 `bison -v' segfaults.
16890 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
16892 * tests/regression.m4: New file.
16893 Include the core of the sample provided by Piotr Gackiewicz.
16894 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
16897 2000-10-04 Akim Demaille <akim@epita.fr>
16899 * src/reader.c (parse_expect_decl): Keep `count' within the size
16903 2000-10-02 Paul Eggert <eggert@twinsun.com>
16905 * bison.s1 (yyparse): Assign the default value
16906 unconditionally, to avoid a GCC warning and make the parser a
16909 2000-10-02 Akim Demaille <akim@epita.fr>
16911 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
16914 2000-10-02 Akim Demaille <akim@epita.fr>
16916 * src/derives.c, src/print.c, src/reduce.c: To ease the
16917 translation, move some `\n' out of the translated strings.
16919 2000-10-02 Akim Demaille <akim@epita.fr>
16921 The location tracking mechanism is precious for parse error
16922 messages. Nevertheless, it is enabled only when `@n' is used in
16923 the grammar, which is a different issue (you can use it in error
16924 message, but not in the grammar per se). Therefore, there should
16925 be another means to enable it.
16927 * src/getargs.c (getargs): Support `--locations'.
16928 (usage): Report it.
16929 * src/getargs.h (locationsflag): Export it.
16930 * src/lex.c (percent_table): Support `%locations'.
16931 * src/reader.c (yylsp_needed): Remove this variable, now replaced
16932 with `locationsflag'.
16933 * doc/bison.texinfo: Document `--locations' and `%locations'.
16935 * tests/calc.m4: Test it.
16937 For regularity of the names, replace each
16938 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
16939 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
16940 In addition replace each `flag' with `_flag'.
16942 2000-10-02 Akim Demaille <akim@epita.fr>
16944 Also test parse error messages, including with YYERROR_VERBOSE.
16946 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
16948 Use it to check the computations.
16949 Use it to check `nonassoc' is honored.
16950 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
16951 `--yyerror-verbose'.
16952 (_AT_CHECK_CALC): Adjust to this option.
16953 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
16955 2000-10-02 Akim Demaille <akim@epita.fr>
16957 Test also `--verbose', `--defines' and `--name-prefix'. Testing
16958 the latter demonstrates a flaw in the handling of non debugging
16959 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
16960 was used in order to simplify:
16976 unfortunately this leads to a CPP conflict when
16977 `--name-prefix=foo' is used since it produces `#define yydebug
16980 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
16981 (YYDPRINTF): New macro.
16983 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
16985 Also test `--verbose', `--defines' and `--name-prefix'.
16987 2000-10-02 Akim Demaille <akim@epita.fr>
16989 Improve the readability of the produced parsers.
16991 * src/bison.s1: Formatting changes.
16992 Improve the comment related to the `$' mark.
16993 (yydefault): Don't fall through to `yyresume': `goto' there.
16994 * src/output.c (output_parser): When the `$' is met, skip the end
16996 New variable, `number_of_dollar_signs', to check there's exactly
16997 one `$' in the parser skeleton.
16999 2000-10-02 Akim Demaille <akim@epita.fr>
17001 * lib/xstrdup.c: New file, from the fileutils.
17002 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
17003 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
17004 instead of strlen + xmalloc + strcpy.
17005 * src/symtab.c (copys): Remove, use xstrdup instead.
17007 2000-10-02 Akim Demaille <akim@epita.fr>
17009 * src/gram.h (associativity): New enum type which replaces the
17010 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
17011 `right_assoc', `left_assoc' and `non_assoc'.
17012 Adjust all dependencies.
17013 * src/reader.c: Formatting changes.
17014 (LTYPESTR): Don't define it, use it as a literal in
17015 `reader_output_yylsp'.
17016 * src/symtab.h (symbol_class): New enum type which replaces the
17017 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
17018 `sunknown', `stoken and `snterm'.
17020 2000-10-02 Akim Demaille <akim@epita.fr>
17022 * src/getargs.c (fixed_outfiles): Rename as...
17023 (yaccflag): for consistency and accuracy.
17024 Adjust dependencies.
17026 2000-10-02 Akim Demaille <akim@epita.fr>
17028 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
17029 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
17030 difficult and introduced a lot of core dump. It turns out that
17031 Bison used an implementation of `xmalloc' based on `calloc', and
17032 at various places it does depend upon the initialization to 0. I
17033 have not tried to isolate the pertinent places, and all the former
17034 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
17035 someone should address this issue.
17037 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
17038 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
17040 Adjust dependencies.
17041 * src/warshall.h: New file.
17044 2000-10-02 Akim Demaille <akim@epita.fr>
17046 Various anti-`extern in *.c' changes.
17048 * src/system.h: Include `assert.h'.
17050 2000-10-02 Akim Demaille <akim@epita.fr>
17052 * src/state.h (nstates, final_state, first_state, first_shift)
17053 (first_reduction): Move their exportation from here...
17054 * src/LR0.h: to here.
17055 Adjust dependencies.
17056 * src/getargs.c (statisticsflag): New variable.
17057 Add support for `--statistics'.
17058 Adjust dependencies.
