14 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
16 * data/push.c (yypushparse): Fix memory leak if yymsg is malloced
17 in a push parser. Reindent slightly to match yacc.c better.
19 2006-10-11 Bob Rossi <bob@brasko.net>
21 * data/push.c (struct yypvars): Remove yymsgbuf, yymsgbuf_ptr, yymsg,
23 (yypvarsinit, yypushparse): Remove init of removed fields.
24 (yypushparse): Use yymsgbuf instead of yymsgbuf_ptr.
26 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
28 * THANKS: Add Paolo Bonzini and Bob Rossi.
30 2006-10-08 Paolo Bonzini <bonzini@gnu.org>
32 * data/c.m4 (b4_copyright, b4_epilogue, b4_location_initial_column,
33 b4_location_initial_line, p4_parse_param, b4_ints_in, b4_flag_if,
34 b4_define_flag_if and uses, b4_basename, b4_syncline, b4_user_code,
35 b4_define_user_cde and uses): Remove.
36 (b4_comment, b4_prefix, b4_sync_start): New.
37 * data/bison.m4: New file, with most of the content removed from c.m4.
38 * src/muscle_tab.h: Use "do {...} while(0)" throughout.
39 * src/output.c (output_skeleton): Pass bison.m4.
40 (prepare): Pass glr_flag and nondeterministic_flag. Pass prefix
43 2006-10-05 Paul Eggert <eggert@cs.ucla.edu>
45 Fix test failure reported by Tom Lane in
46 <http://lists.gnu.org/archive/html/bug-bison/2006-10/msg00000.html>
47 and try to make such failures easier to catch in the future.
48 * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
49 that's now the caller's responsibility.
50 (yyprocessOneStack, yyrecoverSyntaxError, yyparse):
51 Set yychar = YYEOF if it's negative.
52 * tests/actions.at (yylex): Abort if asked to read past EOF.
53 * tests/conflicts.at (yylex): Likewise.
54 * tests/cxx-type.at (yylex): Likewise.
55 * tests/glr-regression.at (yylex): Likewise.
56 * tests/input.at (yylex): Likewise.
57 * tests/regression.at (yylex): Likewise.
58 * tests/torture.at (yylex): Likewise.
60 2006-10-01 Paul Eggert <eggert@cs.ucla.edu>
62 Fix problems with translating English-language diagnostics.
63 * bootstrap: Fix bug introduced in recent bootstrap changes, with
64 respect to bison-runtime pot generation. The YY_ stuff
65 wasn't being captured.
66 * bootstrap.conf (XGETTEXT_OPTIONS_RUNTIME): New var.
67 * po/POTFILES.in: Add src/location.c, src/scan-code.l.
68 * runtime-po/POTFILES.in: Add data/push.c.
70 2006-09-29 Paul Eggert <eggert@cs.ucla.edu>
72 Merge bootstrap changes from coreutils.
74 2006-09-28 Jim Meyering <jim@meyering.net>
76 Automatically generated dependencies are important even
77 when all of the sources in a directory come from gnulib.
78 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
79 option that gnulib-tool adds to what becomes our lib/gnulib.mk.
81 2006-09-23 Jim Meyering <jim@meyering.net>
83 * bootstrap (gnulib_tool_options): Add "--local-dir gl".
85 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
87 * bootstrap: Add support for --force.
88 (usage): New function. Describe usage less tersely.
89 (CVS_only_file): New var.
91 2006-09-21 Paul Eggert <eggert@cs.ucla.edu>
93 * data/push.c (YYPUSH_MORE): Make it an enum instead.
94 (yypushparse): Use YYPUSH_MORE instead of the mystery constant.
95 Adjust white space and comments to match GNU style better.
97 2006-09-20 Bob Rossi <bob@brasko.net>
99 * data/push.c (yyresult_get): Remove function.
100 (YYPUSH_MORE): Add #define.
101 (yypushparse): Modify return value.
103 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
105 * stamp-h.in: Remove; no longer needed.
106 * .cvsignore: Replace autom4te.cache and config.cache with *.cache.
107 Remove config.h, config.hin, intl (no longer created).
108 * lib/.cvsignore: Add config.h, config.hin, configmake.h, inttypes.h,
111 Sync bootstrap from coreutils, as follows:
113 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
115 * bootstrap (symlink_to_gnulib): New function.
116 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
118 (cp_mark_as_generated, slurp, gnulib_files):
119 Avoid making a copy if it's the same as the old version.
120 (gnulib_files): Add support for this variable (used by Bison).
122 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
124 * src/getargs.c (usage): Rework to use conventions similar to
125 coreutils, to make translation a bit easier and the code a bit
126 smaller. Problem reported by Tim Van Holder.
128 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
130 Use some of gnulib's new modules, taken from coreutils.
132 * bootstrap: Sync from coreutils, except add support for gnulib_files.
133 * bootstrap.conf: New file.
134 (gnulib_modules): Add configmake, inttypes, unistd.
135 (XGETTEXT_OPTIONS): Add complain, complain_at,
136 fatal, fatal_at, warn, warn_at, unexpected_end.
137 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
138 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
140 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
142 (GNULIB_AUTOCONF_SNIPPET): Remove.
143 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
145 * lib/.cvsignore: Add inttypes_.h.
146 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
147 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
148 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
149 no-longer-necessary initializations.
150 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
151 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
152 use the unistd module.
153 * src/system.h: Likewise.
154 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
155 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
156 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
157 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
158 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
159 * src/system.h: Include inttypes.h unconditionally, now that we
160 use the inttypes module. Don't bother to include stdint.h, since
161 inttypes.h now does that for us.
162 (LOCALEDIR): Remove, now that we use the configmake module.
163 * src/getargs.c: Include configmake.h.
164 * src/main.c: Likewise.
165 * src/output.c: Likewise.
166 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
167 not from $abs_top_builddir, since config.h moved.
170 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
171 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
173 * src/parse-gram.y (symbol_declaration): Don't put statements
174 before declarations; it's not portable to C89.
175 * src/scan-code.l (handle_action_at): Likewise.
177 * src/scan-code.l: Always initialize braces_level; the old code
178 left it uninitialized and therefore had undefined behavior.
180 Don't attempt to redefine 'assert', since it runs afoul of
181 systems where standard headers (mistakenly) include <assert.h>.
182 Instead, define and use our own alternative, called 'aver'.
183 * src/reader.c: Don't include assert.h, since we no longer
185 * src/scan-code.l: Likewise.
186 * src/system.h (assert): Remove, replacing with....
187 (aver): New function, taking a bool arg. All uses changed.
188 * src/tables.c (pack_vector): Ensure that aver arg is bool,
189 not merely an integer.
191 2006-09-15 Bob Rossi <bob@brasko.net>
193 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
194 * data/c.m4 (YYPUSH): New.
195 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
196 * src/getargs.c (push_parser): New var.
197 * src/getargs.h (push_parser): New declaration.
198 * src/output.c (prepare): Add macro insertion of `push_flag'.
199 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
200 (prologue_declaration): Parse %push-parser.
201 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
202 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
203 list of removed lines from the traces observed.
204 (AT_CHECK_CALC_LALR): Added push parser tests.
206 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
208 * NEWS: Version 2.3a.
209 * configure.ac (AC_INIT): Likewise.
211 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
212 "#define YYSTYPE int" that caused "make maintainer-check" to fail
213 due to header ordering dependencies. I don't know why the #define
216 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
217 runtime cost when YYDEBUG is not defined, and so that some tests
218 that used to fail now work. Problem and initial suggestion by
220 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
221 * data/glr.cc (b4_parser_class_name):
222 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
223 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
224 (yydebug_) [YYDEBUG]: New member.
225 (yycdebug_): Now defined only if YYDEBUG.
226 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
227 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
228 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
230 (debug_stream, set_debug_stream, debug_level, set_debug_level):
231 Define only if YYDEBUG.
232 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
234 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
235 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
236 AT_CHECK_CALC_GLR_CC that are working now.
238 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
240 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
241 We don't need them in glr.cc, and glr.c defines them.
242 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
243 assumes that defining it to anything is the same as defining
244 it to 1. Problem reported by Paolo Bonzini.
246 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
248 * data/c.m4 (b4_null, b4_case): Define.
249 * src/output.c (prepare_symbols): Use b4_null.
250 (user_actions_output): Use b4_case.
252 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
254 * data/glr.c (b4_shared_declarations): Put start-header first,
255 before any #includes that we generate, so that feature-test
256 macros work. Problem reported by Michael Deutschmann in
257 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
258 * data/lalr1.cc: Likewise.
259 * doc/bison.texinfo (Prologue): Document that feature-test macros
260 should be defined before any Bison declarations.
261 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
262 that depend on location.hh after, not before, Bison decls, since
263 we now include location.hh after the first user prologue.
265 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
266 Sander Brandenburg in
267 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
268 Also, fix minor white space and comment issues.
269 (Prologue): Mention that it's better to define feature-test macros
270 before Bison declarations. Problem reported by Michael Deutschmann.
272 * README-cvs: Fix typo: "&" should be "&&". Problem reported
274 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
275 This adjusts to recent gnulib changes.
277 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
279 Finish implementation of per-type %destructor/%printer. Discussed
281 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
283 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
284 * NEWS (2.3+): Add a description of this feature to the default
285 %destructor/%printer description.
286 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
287 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
288 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
289 list node contains a semantic type.
290 * src/symtab.c, src/symtab.h: Extend with a table that associates
291 semantic types with their %destructor's and %printer's.
292 (semantic_type_from_uniqstr, semantic_type_get,
293 semantic_type_destructor_set, semantic_type_printer_set): New functions
294 composing the public interface of that table.
295 (symbol_destructor_get, symbol_destructor_location_get,
296 symbol_printer_get, symbol_printer_location_get): If there's no
297 per-symbol %destructor/%printer, look up the per-type before trying
299 * tests/actions.at (Per-type %printer and %destructor): New test case.
300 * tests/input.at (Default %printer and %destructor redeclared):
301 Extend to check that multiple occurrences of %symbol-default in a
302 single %destructor/%printer declaration is an error.
303 (Per-type %printer and %destructor redeclared, Unused values with
304 per-type %destructor): New test cases.
306 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
308 Require default %destructor/%printer to be declared using
309 %symbol-default instead of an empty symbol list, and start working on
310 new per-type %destructor/%printer. Discussed at
311 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
312 * NEWS (2.3+): Add %symbol-default to example.
313 * bison.texinfo (Freeing Discarded Symbols): Likewise.
314 (Bison Symbols): Add entry for %symbol-default.
315 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
316 (generic_symlist, generic_symlist_item): New nonterminals for creating
317 a list in which each item is a symbol, semantic type, or
319 (grammar_declaration): Use generic_symlist in %destructor and %printer
320 declarations instead of symbols.1 or an empty list.
321 (symbol_declaration, precedence_declaration, symbols.1): Update actions
322 for changes to symbol_list.
323 * src/reader.c: Update for changes to symbol_list.
324 * src/scan-code.l: Likewise.
325 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
326 * src/symlist.c, src/symlist.h: Extend such that a list node may
327 represent a semantic type or a %symbol-default in addition to just an
328 ordinary symbol. Add switched functions for setting %destructor's and
330 * tests/actions.at, tests/input.at: Add %symbol-default to all default
331 %destructor/%printer declarations.
333 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
335 Whether the default %destructor/%printer applies to a particular symbol
336 isn't a question of whether the user *declares* that symbol (in %token,
337 for example). It's a question of whether the user by any means
338 *defines* the symbol at all (by simply using a char token, for
339 example). $end is defined by Bison whereas any other token with token
340 number 0 is defined by the user. The error token is always defined by
341 Bison regardless of whether the user declares it with %token, but we
342 may one day let the user define error as a nonterminal instead.
343 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
344 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
345 the meaning of "user-defined".
346 * tests/actions.at (Default %printer and %destructor for user-declared
347 end token): Rename to...
348 (Default %printer and %destructor for user-defined end token): ...
351 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
352 computation of whether to apply the default, don't maintain a list of
353 every Bison-defined symbol. Instead, just check for a first character
354 of '$', which a user symbol cannot have, and check for the error token.
356 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
358 Don't apply the default %destructor or %printer to the error token,
359 $undefined, or $accept. This change fits the general rule that the
360 default %destructor and %printer are only for user-declared symbols,
361 and it solves several difficulties that are described in the new test
363 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
364 * tests/actions.at (Default %printer and %destructor are not for error
365 or $undefined, Default %printer and %destructor are not for $accept):
368 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
370 Allow %start after the first rule.
371 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
372 when parsing the first rule.
373 (check_and_convert_grammar): Search for it here after all grammar
374 declarations have been parsed. Skip midrules, which have dummy LHS
376 * src/symtab.c (symbol_is_dummy): New function.
377 * src/symtab.h (symbol_is_dummy): Declare it.
378 * tests/input.at (%start after first rule): New test.
380 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
382 Redo some of the previous commit: add back the ability to use
383 non-aliased/undeclared string literals since it might be useful to
384 those declaring %token-table.
385 * src/reader.c (check_and_convert_grammar): Undo changes in previous
386 commit: don't worry about complaints from symbols_pack.
387 * src/symtab.c (symbol_new, symbol_class_set,
388 symbol_check_alias_consistency): Undo changes in previous commit: count
389 each string literal as a new symbol and token, assign it a symbol
390 number, and don't complain about non-aliased string literals.
391 (symbols_pack): Since symbol_make_alias still does not decrement symbol
392 and token counts but does still set aliased tokens to the same number,
393 symbol_pack_processor now leaves empty slots in the symbols array.
395 * tests/regression.at (Undeclared string literal): Remove test case
396 added in previous commit since non-aliased string literals are allowed
398 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
399 remove unnecessary string literal declarations.
400 * tests/sets.at (Firsts): Likewise.
402 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
404 Don't allow an undeclared string literal, but allow a string literal to
405 be used before its declaration.
406 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
407 symbols_pack complained.
408 * src/symtab.c (symbol_new): Don't count a string literal as a new
410 (symbol_class_set): Don't count a string literal as a new token, and
411 don't assign it a symbol number since symbol_make_alias does that.
412 (symbol_make_alias): It's not necessary to decrement the symbol and
413 token counts anymore. Don't assume that an alias declaration occurs
414 before any uses of the identifier or string, and thus don't assert that
415 one of them has the highest symbol number so far.
416 (symbol_check_alias_consistency): Complain if there's a string literal
417 that wasn't declared as an alias.
418 (symbols_pack): Bail if symbol_check_alias_consistency failed since
419 symbol_pack asserts that every token has been assigned a symbol number
420 although undeclared string literals have not.
421 * tests/regression.at (String alias declared after use, Undeclared
422 string literal): New test cases.
423 (Characters Escapes, Web2c Actions): Declare string literals as
425 * tests/sets.at (Firsts): Likewise.
427 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
429 In the grammar scanner, STRING_FINISH unclosed constructs and return
430 them to the parser in order to improve error messages.
431 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
432 SC_BRACED_CODE, SC_PROLOGUE): Implement.
433 * tests/input.at (Unclosed constructs): New test case.
434 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
437 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
440 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
442 Handle string aliases for character tokens correctly.
443 * src/symtab.c (symbol_user_token_number_set): If the token has an
444 alias, check and set its alias's user token number instead of its own,
445 which is set to indicate the alias. Previously, every occurrence of
446 the character token in the grammar overwrote that alias indicator with
448 * tests/input.at (String aliases for character tokens): New test.
450 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
452 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
454 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
456 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
457 to prevent failures when building on older platforms.
458 Check for autopoint failure.
459 Set XGETTEXT_OPTIONS to values that check for C format strings,
460 so that translators are warned about them (this also helps
463 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
464 function, since it simplifies our code a bit.
466 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
467 rather than -W, so we don't get bogus warnings about sign comparisons.
468 Add -Wpointer-arith, since that warning is useful (it reports code
469 that does not conform to C89 and that some compilers reject).
470 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
471 since it's no longer needed.
473 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
475 Clean up scanners a bit.
476 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
477 definitions so gcc won't warn when obstack_for_string is unused.
478 * src/scan-code.l: config.h and system.h are already #include'd by
479 scan-code-c.c, so get rid of them here.
480 * src/scan-gram.l: Likewise.
481 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
482 definitions rather than duplicating the rest of it.
483 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
485 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
487 Suppress signed/unsigned comparison warnings for yycheck.
488 * data/c.m4 (b4_safest_int_type): New macro.
489 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
490 a signed int type, cast it to b4_safest_int_type first.
491 * data/yacc.c: Likewise.
492 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
495 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
497 * doc/bison.texinfo: Fix some typos.
499 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
501 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
502 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
504 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
505 the latest gnulib does this a different way.
506 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
507 translation was patched, so stop omitting it.
509 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
511 Enable declaration of default %printer/%destructor. Make the parser
512 use these for all user-declared grammar symbols for which the user does
513 not declare a specific %printer/%destructor. Thus, the parser uses it
514 for token 0 if the user declares it but not if Bison generates it as
515 $end. Discussed starting at
516 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
517 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
519 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
520 * NEWS (2.3+): Mention.
521 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
522 declare a %destructor for a mid-rule's semantic value. It's just
523 impossible to declare one specific to it.
524 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
525 code. Describe default %destructor form.
526 * src/parse-gram.y (grammar_declaration): Parse default
527 %printer/%destructor declarations.
528 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
529 and symbol_destructor_location_get rather than accessing the destructor
530 and destructor_location members of struct symbol.
531 (symbol_printers_output): Likewise but for %printer's.
532 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
534 * src/symtab.c (default_destructor, default_destructor_location,
535 default_printer, default_printer_location): New static global
536 variables to record the default %destructor and %printer.
537 (symbol_destructor_get, symbol_destructor_location_get,
538 symbol_printer_get, symbol_printer_location_get): New functions to
539 compute the appropriate %destructor and %printer for a symbol.
540 (default_destructor_set, default_printer_set): New functions to set the
541 default %destructor and %printer.
542 * src/symtab.h: Prototype all those new functions.
543 * tests/actions.at (Default %printer and %destructor): New test to
544 check that the right %printer and %destructor are called, that they're
545 not called for $end, and that $$ and @$ work correctly.
546 (Default %printer and %destructor for user-declared end token): New
547 test to check that the default %printer and %destructor are called for
548 a user-declared end token.
549 * tests/input.at (Default %printer and %destructor redeclared, Unused
550 values with default %destructor): New tests to check related grammar
553 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
555 Clean up handling of %destructor for the end token (token 0).
556 Discussed starting at
557 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
559 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
561 Make the skeletons consistent in how they pop the end token and invoke
563 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
564 state, which has token number 0, since this would invoke the
565 %destructor for the end token.
566 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
567 until after shifting the end token, or else it won't be popped.
568 * data/yacc.c (yyparse): Likewise.
570 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
571 it's the end token. Upon termination, destroy an unshifted lookahead
572 even when it's the end token.
573 * data/lalr1.cc (yy::parser::parse): Likewise.
574 * data/yacc.c (yyparse): Likewise.
576 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
577 value warnings for the end token when the user gives the end token a
580 * tests/actions.at (Printers and Destructors): Test all the above.
582 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
584 Update to latest gnulib and gettext versions.
585 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
587 (gnulib_files): Add m4/warning.m4. Don't worry about files
588 overwritten by autopoint.
589 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
590 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
592 Don't use autoreconf; instead, invoke autopoint etc. by hand,
593 so that we can remove the intl files at a better time.
594 (intl_files_to_remove): Remove aclocal.m4, since it gets
595 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
596 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
597 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
598 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
599 Remove datarootdir hack; no longer needed.
600 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
601 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
602 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
604 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
605 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
607 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
609 * bootstrap: Adjust to today's change to gnulib-tool by invoking
610 it with --assume-autoconf='latest-stable'.
612 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
614 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
615 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
617 * src/muscle_tab.h (muscle_grow): Replace the header comments with
618 those from muscle_tab.c since the old ones are misleading.
620 2006-07-13 Akim Demaille <akim@epita.fr>
622 Support %define "KEY" {VALUE}.
623 * src/scan-code.h, src/scan-code.l (translate_action)
624 (translate_rule_action, translate_symbol_action, translate_code):
625 Return char *, not const char *.
626 * src/parse-gram.y (declaration): Rename as...
627 (prologue_declaration): this.
628 (string_content): Remove this nonterminal, use STRING.
629 (braceless, content, content.opt): New nonterminal.
631 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
633 * src/scan-gram.l (getargs.h): Don't include it.
635 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
637 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
638 rather than a for-loop that declares a local bool variable. This
639 should work around a compatibility problem with a Cray x1e C++
640 compiler reported by Hung Nguyen in
641 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
642 The for-loop was introduced in the 2004-11-17 change but I don't
643 know why it was needed.
645 2006-07-12 Akim Demaille <akim@epita.fr>
647 * data/c.m4: Comment changes.
649 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
651 * src/complain.c (error_message, ERROR_MESSAGE): New.
653 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
654 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
656 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
658 * NEWS: Instead of %union, you can define and use your own union type
659 YYSTYPE if your grammar contains at least one <type> tag.
660 Your YYSTYPE need not be a macro; it can be a typedef.
661 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
662 (Union Decl, Decl Summary): Document this.
663 * data/glr.c (YYSTYPE): Implement this.
664 * data/glr.cc (YYSTYPE): Likewise.
665 * data/lalr1.cc (YYSTYPE): Likewise.
666 * data/yacc.c (YYSTYPE): Likewise.
667 * src/output.c (prepare): Output tag_seen_flag.
668 * src/parse-gram.y (declaration, grammar_declaration):
669 Use 'union_seen' rather than 'typed' to determine whether
670 %union has been seen, since grammars can now be typed without
672 (symbol_declaration, type.opt, symbol_def):
673 Keep track of whether a tag has been seen.
674 * src/reader.c (union_seen, tag_seen): New vars.
676 * src/reader.h (union_seen, tag_seen, typed): Likewise.
677 * src/scan-code.l (untyped_var_seen): New variable.
678 (handle_action_dollar): Adjust to above changes.
679 (handle_action_dollar, handle_action_at):
680 Improve overflow checking for outlandish numbers.
681 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
682 avoid new diagnostics generated by above changes.
683 * tests/regression.at (YYSTYPE typedef): Add test to check
684 for type tags without %union.
686 * src/symlist.c (symbol_list_length): Return int, not unsigned
687 int, since callers expect int. This may need to get revisited
688 once we have proper integer overflow checking.
690 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
691 object is now static.
693 * src/getargs.c (flags_argmatch): Return void, not int,
694 to pacify ./configure --enable-gcc-warnings.
696 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
697 since last_string is already defined to FLEX_PREFIX (last_string).
699 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
701 Implement --warnings/-W.
702 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
704 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
706 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
707 (warnings_args, warnings_types): New.
708 (getargs, short_options, long_options): Accept -W/--warnings.
709 Sort the options by alphabetical order, upper case letter right
710 before its lower case.
712 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
714 Change %merge result type clash warnings to errors. Discussed at
715 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
716 * src/reader.c (record_merge_function_type): Use complain_at.
717 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
718 declared later): Update test case results.
720 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
722 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
723 to be in alphabetical order.
724 (trace_args): Spelling fixes.
726 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
728 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
729 so they don't collide with user-defined macros.
730 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
731 this was never guaranteed, and now that we're using gnulib stdint,
732 which defines int_fast16_t to long int, the problem is exposed.
734 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
736 * data/c.m4 (b4_basename): Simplify a bit, since we don't
737 need the full POSIX semantics (and weren't implementing them
740 Adjust to Autoconf 2.60 and today's gnulib.
741 * bootstrap (gnulib_modules): Add stdint.
742 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
744 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
745 since stdint needs the former and wcwidth (which is now required
746 by mbswidth) needs the latter.
747 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
748 work around a compatibility glitch between gettext 0.14.6 and
750 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
751 Do not check for uintptr_t, since new stdint module does the right
753 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
754 Add stdint.h, stdint_.h, wcwidth.h.
755 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
756 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
757 stdint.m4, wchar_t.m4, wcwidth.m4.
758 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
759 usual order for ../lib/*.h files.
760 (file_name_split): Use last_component, not base_name, to adjust
762 * src/parse-gram.h: Include <strverscmp.h> in the usual order
763 for ../lib/*.h files.
764 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
765 Define unconditionally, since we now assume the stdint module.
766 * src/scan-skel.l: Include <dirname.h>.
767 (BASE_QPUTS): Use last_component, not base_name.
768 * src/system.h: Include <unlocked-io.h> in the usual order
769 for ../lib/*.h files. Include <stdint.h> unconditionally,
770 since we now use the stdint module.
771 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
772 HAVE_UINTPTR_T, since we now use the stdint module.
773 (base_name): Remove decl, since files now include <dirname.h>
776 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
778 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
780 * data/yacc.c, data/glr.c, data/location.cc: Use them.
781 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
783 * tests/calc.at: Adjust.
785 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
787 * data/c.m4 (b4_basename): New.
788 (b4_syncline): Also output the location of its invocation (from
790 (b4_user_action, b4_define_user_action, b4_user_actions)
791 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
792 (b4_user_stype): New.
793 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
795 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
797 In the grammar file, the first column is 1 not 0 on the first line as
799 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
800 * tests/input.at (Torturing the Scanner): Update output.
802 * src/scan-gram.l (scanner_cursor): Declare it static.
804 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
806 In warnings, say "previous declaration" rather than "first
808 * src/symtab.c (redeclaration): Do that here.
809 * src/reader.c (record_merge_function_type): In the case of a result
810 type clash, report the previous declaration rather than the very first
811 one in the grammar file.
812 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
813 declared later): Add a third declaration to check this behavior.
814 * tests/input.at (Incompatible Aliases): Update output.
816 2006-06-27 Akim Demaille <akim@epita.fr>
818 * doc/Doxyfile.in: New.
819 * doc/Makefile.am: Use it.
820 * src/lalr.h, src/symtab.h: Initial doxygenation.
822 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
824 Don't miss %merge result type warnings just because the LHS types are
825 declared after the %merge. This continues the effort of the previous
827 * src/reader.c (get_merge_function): Don't set the merger type yet.
828 (record_merge_function_type): New function for setting the merger type
829 and checking for clashes.
830 (grammar_current_rule_merge_set): Set the location of the %merge for
832 (packgram): Invoke record_merge_function_type for each rule now that
833 all symbol type declarations have been parsed.
834 * src/reader.h (merger_list.type_declaration_location): New member
835 storing the location of the first %merge from which the type for this
836 merging function was derived.
837 * src/symlist.h (symbol_list.merger_declaration_location): New member
838 storing the location of a rule's %merge, if any.
839 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
840 declared later): New test to catch the error fixed by the above patch.
842 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
844 Get action warnings (grammar_rule_check) right even when symbol
845 declarations appear after the rules. Discussed at
846 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
848 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
849 Don't mistake the type of $$ in a midrule to be that of its parent
851 * src/reader.c (grammar_current_rule_end): Don't invoke
852 grammar_rule_check yet since not all symbol declarations may have been
854 (grammar_midrule_action): Likewise.
855 Don't record whether the midrule's $$ has been used yet since actions
856 haven't been translated yet.
857 Record the midrule's parent rule and its RHS index within the parent
859 (grammar_current_rule_action_append): Don't translate the action yet
860 since not all symbol declarations may have been parsed yet and, thus,
861 warnings about types for $$, $n, @$, and @n can't be reported yet.
862 (packgram): Translate the action and invoke grammar_rule_check now that
863 all symbol declarations have been parsed.
864 * src/scan-code.l (handle_action_dollar): Now that this is invoked
865 after parsing the entire grammar file, the symbol list here in the case
866 of a midrule is actually the midrule's empty RHS, so reference its
867 parent rule's RHS where necessary.
868 On the other hand, now that you can already know it's a midrule, you
869 aren't forced to think $$ has the same type as its parent rule's $$.
870 (handle_action_at): In the case of a midrule, reference the parent rule
872 * src/symlist.c (symbol_list_new): Initialize new midrule-related
874 (symbol_list_length): Now that this is invoked after all rules have
875 been parsed, a NULL symbol (rather than a NULL symbol list node)
876 terminates a rule. symbol_list_print already does this correctly.
877 * src/symlist.h (symbol_list.midrule_parent_rule,
878 symbol_list.midrule_parent_rhs_index): New members so that midrules can
879 remember their relationships with their parents.
880 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
881 fixed by the above patch.
882 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
884 (Unused values): ... this old test case and...
885 (Unused values before symbol declarations): ... this new test case.
886 This one is the same as `Unused values' except that all symbol
887 declarations appear after the rules in order to catch the rest of the
888 errors fixed by the above patch.
890 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
893 * src/reader.c (current_rule): Declare it static since it's no longer
894 used outside this file.
895 (grammar_current_rule_action_append): Remove redundant arguments from
896 translate_rule_action invocation.
897 * src/reader.h (current_rule): Remove this unused extern.
898 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
899 * src/scan-code.l (translate_rule_action): Likewise.
901 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
903 Clean up yesterday's patch.
904 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
906 * src/reader.c (grammar_current_rule_action_append): ... here for
907 consistency with grammar_current_rule_symbol_append.
908 * tests/regression.at (Braced code in declaration in rules section):
909 Make yyerror and yylex static as usual.
911 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
913 Fix bug that mistakes braced code in a declaration in the rules section
914 to be a rule action. Mentioned at
915 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
916 * src/scan-gram.l: Move midrule action detection from the start of the
917 scanning of any braced code to...
918 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
919 action. For readability, use $2 and @2 rather than the equivalent
921 * tests/regression.at (Braced code in declaration in rules section):
922 New test to catch the error fixed by the above patch.
924 Work on code readability some.
925 * src/scan-code.l (current_rule): Get rid of this misleading and
926 redundant declaration: it's actually extern'ed in reader.h.
927 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
928 translate_action): Add a rule argument and use it instead of the global
930 (translate_rule_action): This already receives current_rule through an
931 argument, so pass it on to translate_action instead of assigning
932 current_rule to current_rule.
933 (translate_symbol_action, translate_code): Pass rule = NULL to

938 Rename %before-definitions to %start-header and %after-definitions to
939 %end-header. Don't use these declarations to separate pre-prologue
940 blocks from post-prologue blocks. Add new order-independent
941 declarations %before-header and %after-header as alternatives to the
942 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
943 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.

962 (declaration): Update token names and m4 macro names.
963 When parsing %end-header and %start-header, invoke translate_code
964 before muscle_code_grow, and no longer set global booleans to remember
965 whether these declarations have been seen.
966 Parse new %after-header and %before-header.
967 * src/reader.c (before_definitions, after_definitions): Remove.

984 * data/c++.m4 (b4_define_location_comparison): New boolean %define
985 declaration indicating whether filename_type has an operator==. If
986 filename_type is `std::string', it defaults to `1', `0' otherwise.
987 * data/location.cc: Iff b4_define_location_comparison is `1', add
988 operator== and operator!= for class position and for class location.

1001 Don't put the pre-prologue in the header file. For the yacc.c code
1002 file and the glr.c header and code files, move the pre-prologue before
1003 the token definitions. Add new %before-definitions and
1004 %after-definitions to declare code that will go in both the header file
1005 and code file. Discussed at
1006 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
1007 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,

1014 Add new b4_after_definitions at the end.
1015 * data/glr.cc (b4_pre_prologue): Replace with...
1016 (b4_before_definitions): ... this in the header file.
1017 (b4_after_definitions): New near the end of the header file.
1018 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
1019 code file right before including the header file.
1020 (b4_before_definitions): New in the previous position of
1021 b4_pre_prologue in the header file.
1022 (b4_after_definitions): New near the end of the header file.
1023 * data/yacc.c: Clean up some m4 quoting especially in the header file.
1024 (b4_token_enums_defines): In the code file, move to right before
1025 YYSTYPE for consistency with the header file.
1026 (b4_before_definitions): New right before b4_token_enums_defines in
1027 both the header and code file.
1028 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
1029 header and code file.
1030 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
1031 of prologues for %union dependencies.
1032 (Bison Declaration Summary): In %defines description, mention the
1033 effect of %before-definitions and %after-definitions on the header
1035 (Calc++ Parser): Forward declare driver in a %before-definitions rather
1036 than in the pre-prologue so that make check succeeds.
1037 (Bison Symbols): Add entries for %before-definitions and
1039 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
1040 %before-definitions.
1041 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
1042 (declaration): Parse those declarations and append to
1043 b4_before_definitions and b4_after_definitions, respectively.
1044 * src/reader.c (before_definitions, after_definitions): New bools to
1045 track whether those declarations have been seen.
1046 (prologue_augment): Add to the post-prologue if %union,
1047 %before-definitions, or %after-definitions has been seen.
1048 * src/reader.h (before_definitions, after_definitions): New extern's.
1049 * src/scan-gram.l: Scan the new declarations.
1050 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
1051 prologue block in a %before-definitions or a %after-definitions based
1052 on whether the %union is declared.

1054 definitions without --yacc): Move tests for token definitions into the
1055 post-prologue since token names are no longer defined in the
1058 2006-06-20 Akim Demaille <akim@epita.fr>
1060 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
1061 (symbol_get): Use it.

1064 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
1066 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
1067 build succeeds when configured with --enable-gcc-warnings.

1071 * src/parse-gram.y (char_name): New function.
1072 (CHAR, STRING, string_content): For %printer, properly escape.
1073 (ID): Prefer fputs to fprintf.
1074 (id): Reindent to be consistent with other rules.
1075 Properly quote char.
1077 The Translation Project changed its way of publishing translations
1078 to maintainers. I haven't received any responses to my request
1079 for supporting the old way, or for documenting the new way. I
1080 have modified 'bootstrap' to use screen scraping
1081 (in this case, HTML scraping). This is unreliable and inelegant,
1082 but I don't see any better way. Yuck.
1083 * bootstrap (TP_URL, WGET_COMMAND): New vars.
1084 (get_translations): New function, which uses HTML scraping to
1085 deduce locations of latest translations.
1086 Use this function to grab both bison and bison-runtime .po files.
1087 Don't bother priming the pump for the runtime-po domain any more,
1088 as it's now translated better than bison is.
1090 2006-06-19 Akim Demaille <akim@epita.fr>
1092 * src/scan-gram.l: No longer "parse" things after `%union' until
1093 `{'. Rather, return a single "%union" token.
1094 No longer make symbols: return strings, and leave the conversion
1095 to symbols to the parser.
1096 (SC_PRE_CODE, token_type): Remove.
1097 * src/parse-gram.y (%union): New field `character'.
1100 (ID, ID_COLON): Now that the scanner no longer makes them
1101 identifiers, adjust all uses to invoke symbol_get.
1102 (id_colon): New, wraps the conversion from string to symbol.
1103 (%union): Accept a possible union_name.
1104 (symbol): Now can be a char.
1105 * data/c.m4 (b4_union_name): Leave a default value.
1106 * data/glr.c, data/yacc.c: Use it.
1108 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
1110 For associating token numbers with token names for "yacc.c", don't use
1111 #define statements unless `--yacc' is specified; always use enum
1112 yytokentype. Most important discussions start at:
1113 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
1114 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
1116 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
1117 * NEWS (2.3+): Mention.
1118 * data/c.m4 (b4_yacc_if): New.
1119 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
1121 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
1122 on token name definitions.
1123 * src/getargs.c (usage): Capitalize `Yacc' in English.
1124 * src/output.c (prepare): Define b4_yacc_flag.
1125 * tests/regression.at (Early token definitions): Test that tokens names
1126 are defined before the pre-prologue not just before the post-prologue.
1127 Remove this test case and copy to...
1128 (Early token definitions with --yacc): ... this to test #define's.
1129 (Early token definitions without --yacc): ... and this to test enums.
1131 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
1133 * NEWS: Reword the post-2.3 change to not be so optimistic about
1134 removing the old "look-ahead" spelling.
1135 Update previous look-ahead/lookahead change reports.
1136 * REFERENCES: look-ahead -> lookahead (since that's
1137 what he actually wrote).
1138 * doc/refcard.tex: look ahead -> lookahead,
1139 look-ahead -> lookahead
1141 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
1143 For consistency, use `lookahead' instead of `look-ahead' or
1144 `look_ahead'. Discussed starting at

1221 Bison without installing the yacc script.
1223 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
1225 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
1226 and yytext if they're already #define'd.
1227 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
1228 * src/scan-code-c.c: ... here.

1258 Extract the parsing of user actions from the grammar scanner.
1259 As a consequence, the relation between the grammar scanner and
1260 parser is much simpler. We can also split "composite tokens" back
1262 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
1263 * src/scan-gram.l (add_column_width, adjust_location): Move to and

1325 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
1327 Between Bison releases, manually append `+' to the previous Bison
1328 release number, and use that as a signal to automatically print the
1329 ChangeLog's CVS Id keyword from --version. Discussed starting at
1330 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
1331 * ChangeLog: Add Id header.
1332 * configure.ac (AC_INIT): Append `+' to `2.3'.
1333 * src/.cvsignore: Add revision.c.
1334 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
1335 (BUILT_SOURCES): Add revision.c.
1336 (revision.c): New target rule. This file defines a new global variable
1337 named revision. It initializes it with either the Id from ChangeLog
1338 or, if VERSION doesn't contain `+', with the empty string.
1339 * src/getargs.c (version): Print the value of revision.
1340 * src/revision.h: Extern revision.
1342 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1344 * NEWS: Version 2.3.
1345 * configure.ac (AC_INIT): Likewise.
1347 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1349 * data/glr.c (YYRECOVERING): Define to be a function-like macro
1350 with no arguments, not as an object-like macro. This is for
1351 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
1352 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
1353 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
1356 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
1358 * src/getargs.c (usage): Back out yesterday's modification of the
1359 --help output so that we don't have to wait for translation before
1362 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
1364 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".

1369 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
1371 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
1373 * data/yacc.c (yy_reduce_print): Omit trailing white space in
1374 generated source code. Problem reported by Frans Englich in
1375 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
1377 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
1379 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
1380 shell, not within 'make', so that 'make' by an ordinary builder
1381 (using GNU make) does not worry about configuring gzip. This also
1382 works around a bug reported independently by Keith Thompson and by
1383 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
1384 stderr rather than stdout, messing up the build logs.
1386 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
1388 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
1389 to make sure that YYID will never be unused. This fixes a 'make
1390 maintainer-check' failure caused by the recent changes to the 'Trivial
1391 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
1393 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
1395 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
1397 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
1398 state before an empty RHS is always resolved here. Only the location
1399 of that state is guaranteed to be resolved, and that's enough. This
1400 fixes the remaining bug reported by Derek M. Jones in
1401 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
1402 * tests/glr-regression.at (Uninitialized location when reporting
1403 ambiguity): Test the above case.
1404 Also, the embedded comments in this test case claim it checks the case
1405 of an empty RHS that has inherited the initial location. However, the
1406 corresponding LHS was already resolved, so yyresolveLocations didn't
1407 actually have reason to modify it. Fix this by forcing
1408 nondeterministic operation at the beginning of the parse.
1410 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
1412 * data/c.m4 (b4_yy_symbol_print_generate):
1413 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
1414 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
1415 of the bugs reported today by Derek M Jones in
1416 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
1417 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
1418 defined to be a type name without parens or brackets.
1419 (Location Type): Similarly for YYLTYPE.
1420 * tests/regression.at (Trivial grammars): Put in a test for this
1421 bug that will be caught by 'make maintainer-check' (though not,
1422 alas, by 'make check' unless your compiler is picky).
1424 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>

1431 * data/glr.c (yyreportTree): Make room in yystates for the state
1432 preceding the RHS. This fixes the segmentation fault reported by Derek
1434 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
1435 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
1436 to the user. Reported for yyreportTree by Derek M. Jones later in the
1438 * THANKS: Add Derek M. Jones.
1439 Update my email address.
1440 Fix typo in Steve Murphy's name.
1442 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
1444 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
1445 checking against YYLAST that caused the parser to miss a potential
1446 alternative in its diagnostic.
1447 Problem reported by Maria Jose Moron Fernandez in
1448 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.

1450 * data/yacc.c (yysyntax_error): Likewise.
1451 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
1452 tokens, in case we run into an older C compiler.
1453 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
1454 Use them to check for the off-by-one error fixed above.
1456 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
1457 YYSIZE_T, not size_t.
1458 * tests/regression.at (Trivial grammars): New test, to catch
1459 the error fixed by the above patch.
1461 2006-05-14 Akim Demaille <akim@lrde.epita.fr>

1467 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
1469 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
1470 * data/glr.cc: b4_location_flag is now b4_locations_flag.
1472 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
1474 Implement --trace=m4.
1475 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
1476 * src/output.c (output_skeleton): When set, pass -dV to m4.
1478 Factor the handling of flags in m4.
1479 * src/output.c (prepare): Rename the muscle names debug, defines,
1480 error_verbose to debug_flag, defines_flag, error_verbose_flag.
1481 * data/c.m4: Adjust.
1482 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
1483 Use b4_define_flag_if to define other b4_FLAG_if macros.
1484 (b4_location_if): As a consequence, rename as...
1485 (b4_locations_if): this, for consistency.
1486 Adjust all the skeletons.
1488 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
1490 * etc/bench.pm: Shorten bench names.
1492 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
1494 * src/output.h, src/output.c (error_verbose): Move to...

1497 Adjust dependencies.
1499 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
1501 * data/c.m4 (b4_copyright): Put the special exception for Bison
1502 skeletons here, so we don't have to put it in each skeleton. All
1503 uses changed. Suggested by Akim Demaille. Also, wrap the
1504 copyright notice, in case it is longer than 80 columns. Replace
1505 comma by newline after title.
1507 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
1509 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
1510 incompatibility, not a bug. Mention that it wasn't fixed as of

1515 * examples/extexi: Enforce the precedence of concatenation over

1519 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
1521 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
1522 with the member "token".
1523 Reported by Martin Nylin.
1525 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
1527 * data/glr.c: Switch to Bison 2.2 special-exception language in
1528 the copyright notice. Use more-regular format for titles and

1540 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
1542 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
1543 that variable and the line breaks the bootstrap. Problem reported
1544 by Juan M. Guerrero.

1564 Problem reported by Bob Rossi.
1566 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
1568 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
1569 and didn't really work.
1570 For the index, use @ifnotinfo, not @iftex.
1571 Minor cleanups of spacing and terminology.
1573 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
1575 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
1576 of AT_NAME_PREFIX when %name-prefix is not used.
1578 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
1580 Apply --prefix to C++ skeletons too: they change the namespace.
1581 The test suite already exercize these cases.
1582 * data/c++.m4 (b4_namespace): New.
1583 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
1584 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
1585 * data/yacc.c, data/glr.c: Remove a useless `[]'.
1586 * doc/bison.texinfo: Document it.
1587 (Option Cross Key): Use @multitable in all formats. It looks
1588 nicer, even in TeX outputs.
1589 (Rules): Use the same code whatever the output type is.
1590 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
1591 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
1592 * tests/calc.at: Use it, instead of hard coding `yy'.

1613 Fix two nits reported by twlevo, plus one more that I discovered.
1615 * src/assoc.h (assoc_to_string): Give a name to the arg, as
1616 this is the usual Bison style.
1617 * src/location.h (location_print): Likewise.
1619 * src/reader.h (token_name): Likewise.
1621 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
1623 Fix some nits reported by twlevo.
1624 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
1625 and "POSIX". Use more-modern syntax for URLs. Mention C++
1626 and ask for Java. Don't hardwire OS version numbers. Add
1628 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
1629 * src/conflicts.c (solved_conflicts_obstack): Now static.
1631 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
1633 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
1634 page. Say "you can use it" not "you may use it" as on the web page;
1635 we're describing capabilities not granting permission.
1637 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
1639 * data/glr.c (yyresolveLocations): Rename local variables to avoid
1640 shadowing warnings. Use usual patter for iterating through RHS.
1641 * tests/glr-regression.at
1642 (Uninitialized location when reporting ambiguity):
1643 Modify yylex so that it uses its argument, rather than trying
1644 to rely on ARGSUSED (which doesn't work for gcc with warnings).
1645 const char -> char const.
1647 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
1648 Don't use tabs inside commands; it messes up 'ps'.
1649 Problem reported by twlevo.
1651 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
1653 * tests/glr-regression.at (Uninitialized location when reporting
1654 ambiguity): New test case.
1655 * data/glr.c (yyresolveLocations): New function, which uses
1657 (yyresolveValue): Invoke yyresolveLocations before reporting an
1659 * doc/bison.texinfo (Default Action for Locations): Note
1660 YYLLOC_DEFAULT's usage for ambiguity locations.
1661 (GLR Semantic Actions): Cross-reference those notes.
1663 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
1665 * tests/glr-regression.at (Leaked semantic values when reporting
1666 ambiguity): Remove unnecessary union and type declarations.
1667 (Leaked lookahead after nondeterministic parse syntax error): New test
1669 * data/glr.c (yyparse): Check for zero stacks remaining before
1670 attempting to shift the lookahead so that you don't lose it.
1672 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
1674 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
1675 * tests/glr-regression.at (Leaked semantic values when reporting
1676 ambiguity): New test case.
1677 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
1678 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
1679 now unnecessary yystackp parameter.
1680 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
1681 destructors can be called.
1683 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
1684 in existing testcases.
1686 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
1688 Don't leak semantic values for parent RHS when a user action cuts the
1689 parser, and clean up related code a bit.
1690 * tests/glr-regression.at (Leaked merged semantic value if user action
1691 cuts parse): Rename to...
1692 (Leaked semantic values if user action cuts parse): ... this. Add check
1693 for leaked parent RHS values.
1694 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
1695 between an unresolved state (non-empty chain of semantic options) and
1696 an incomplete one (signaled by an empty chain).
1697 (yyresolveStates): Document the interface. Move all manipulation of a
1698 successfully or unsuccessfully resolved yyGLRState to...
1699 (yyresolveValue): ... here so that yyresolveValue always leaves a
1700 yyGLRState with consistent data and thus is easier to understand.
1701 Remove the yyvalp and yylocp parameters since they are always just
1702 taken from the yys parameter. When reporting a discarded merged value
1703 in debugging output, note that it is incompletely merged. Document the
1705 (yyresolveAction): If resolving any of the RHS states fails, destroy
1706 them all rather than leaking them. Thus, as long as user actions are
1707 written to clean up the RHS correctly, yyresolveAction always cleans up
1708 the RHS of a semantic option. Document the interface.
1710 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>

1713 led to a segmentation fault in GNU Pascal. Problem reported
1716 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
1718 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
1719 mid-rule action inside a nonterminal symbol in order to declare a
1720 destructor for its semantic value.

1774 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
1775 nodist_PROGRAMS, since we don't need to actually compile the
1776 example if we're just doing a plain 'make'. This avoids bothering
1777 the installer unnecessarily about problems due to weird C++

1785 than #include "...", and compile with -I'.'. The old method was
1786 not portable, according to Posix and the C standard, and it does
1787 not work with Sun C 5.7, where previous #line directives affect

1827 During deterministic GLR operation, user actions should be able to
1828 influence the parse by changing yychar. To make this easier to fix and
1829 to make glr.c easier to evolve in general, don't maintain yytoken in
1830 parallel with yychar; just compute yytoken when needed.

1837 yychar rather than *yytokenp to determine the current lookahead.

1857 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
1858 got from <http://bro-ids.org/download.html>. The bug is that
1859 when two actions appeared in succession, the second one was
1860 scanned before the first one was added to the grammar rule
1861 as a midrule action. Bison then output the incorrect warning
1862 "parse.y:905.17-906.36: warning: unused value: $3".

2124 in the yychar entry.
2125 In the yychar entry, remove mention of the local yychar case (pure
2126 parser) since this is irrelevant information when writing semantic
2127 actions and since it's already discussed in `Bison Symbols' where
2128 yychar is otherwise described as an external variable.
2129 In the yychar entry, don't call it the `current' look-ahead since it
2130 isn't when semantic actions are deferred.
2131 In the yychar and yyclearin entries, add note about deferred semantic
2133 Add yylloc and yylval entries discussing look-ahead usage.
2134 (Look-Ahead Tokens): When discussing yychar, don't call it the

2159 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
2160 from which the RHS is taken. Set the lookahead members of the new

2163 yyaddDeferredAction.

2189 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
2191 * data/glr.c (yyresolveValue): When merging semantic options, if at
2192 least one user action succeeds but a later one cuts the parse, then
2193 destroy the semantic value before returning rather than leaking it.
2194 (yyresolveStates): If a user action cuts the parse and thus
2195 yyresolveValue fails, ignore the (unset) semantic value rather than
2196 corrupting the yyGLRState, and empty the semantic options list since
2197 the user actions should have called all necessary destructors.
2198 Simplify code with YYCHK.
2199 * tests/glr-regression.at (Corrupted semantic options if user action
2200 cuts parse): New test case.
2201 (Undesirable destructors if user action cuts parse): New test case.

2501 Work around portability problem on Solaris 10: flex-generated

2843 * data/m4sugar/m4sugar.m4 (_m4_map): New macro.
2844 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
2846 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
2848 Undo the parts of the unlocked-I/O change that substituted
2849 putc or puts for printf. This might hurt performance a bit,
2850 but some people prefer the printf style.
2851 * data/c.m4 (yysymprint): Prefer printf to puts and putc.
2852 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.

2879 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
2881 Use unlocked I/O for a minor performance improvement on hosts like
2882 GNU/Linux and Solaris that support unlocked I/O. The basic idea
2883 is to use the gnlib unlocked-io module, and to prefer putc and
2884 puts to printf when either will work (since the latter doesn't
2885 come in an unlocked flavor).
2886 * bootstrap (gnulib_modules): Add unlocked-io.

2905 * src/system.h: Include unlocked-io.h rather than stdio.h.
2907 * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as

2957 to allow support for non-posix systems. This is a no-op function
2960 * src/output.c (output_skeleton): Use end_of_output_subpipe() to
2961 handle the lack of pipe/fork functionality on non-posix systems.

3045 local variables whose names begin with 'yy'.
3046 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
3047 Trivial changes from Joel E. Denny.
3049 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
3051 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
3052 don't use alloca any more.
3054 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
3055 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
3056 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.

3067 This works a bit better with glibc, if user code has already included

3086 (yysyntax_error): New function.
3087 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if

3089 Instead, reallocate buffers twice as big each time, so that
3090 we waste at most half the allocated memory. Start with a small
3091 (128-byte) buffer that will suffice in most cases anyway.
3092 Use yysyntax_error to do most of the work.
3094 * doc/bison.texinfo (Error Reporting, Table of Symbols):
3095 yynerrs is the number of errors reported, not the number of

3104 2005-09-19 Akim Demaille <akim@epita.fr>
3106 Remove the traits, failed experiment.
3107 It never proved useful, and anyway because of the current
3108 definition, it was not possible to have several specialization of
3109 this traits, making it useless.
3110 * data/lalr1.cc (yy:traits): Remove.
3111 Inline its definitions in the parser class.
3113 2005-09-19 Akim Demaille <akim@epita.fr>

3136 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
3137 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
3138 is not defined. This is an awful hack, but it's enough for now.
3139 All callers changed.
3140 * tests/glr-regression-at (make_value): Args are const pointers now,
3141 to avoid GCC warning.
3142 (Duplicated user destructor for lookahead): New test. Currently
3143 skipped. It fails on my host but I'm not sure it'll always fail.
3145 2005-09-16 Akim Demaille <akim@epita.fr>
3147 * src/symtab.h (struct symbol): Declare the printer and destructor
3148 as const, to avoid accidental calls to free.

3165 * data/lalr1.cc (yylex_): Remove, inline its code.
3166 (yyreport_syntax_error_): Remove, replaced by...
3167 (yysyntax_error_): this which returns a string and leaves to the
3168 caller the call to the users' error function.

3170 Move from members of the parser object...
3171 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):

3195 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
3196 do anything if $@ exists. This reverts part of the 2005-07-07
3199 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
3201 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
3202 contains obsolete information and isn't worth distributing as a
3203 separate file anyway.
3204 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
3205 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.

3212 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
3213 Suggested by twlevo@xs4all.nl.
3215 * data/glr.c (YYCHK1): Do not assume YYE is in range.

3217 Problem reported by twlevo@xs4all.nl.
3219 * doc/bison.texinfo: Don't use "filename", as per GNU coding
3220 standards. Use "file name" or "file" or "name", depending on
3222 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
3223 not to hack/foo.tab.c.
3224 (Calc++ Top Level): 2nd arg of main is not const.
3225 * data/glr.c: b4_filename -> b4_file_name.

3255 (User destructor after an error during a split parse): New test case.
3256 Problem reported by Joel E. Denny in:

3288 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
3290 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
3291 lib-prefix.m4, po.m4.
3293 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
3294 in yydestruct diagnostic, since it might not be an error.
3295 Problem reported by Joel Denny near end of
3296 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
3297 * data/lalr1.cc (yyerturn): Likewise.
3298 * data/yacc.c (yyreturn): Likewise.
3299 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
3301 * src/files.c: Remove obsolete FIXME comment.
3303 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
3304 with the other templates, and to fix bogus run-on messages such
3305 as the one reported at the end of
3306 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
3307 All callers changed to avoid the newline.
3308 (yyprocessOneStack): Output two lines rather than one, to accommodate
3309 the above change. This changes the debug output format slightly.
3311 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
3312 reported by Joel E. Denny in
3313 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
3315 * tests/glr-regression.at (Duplicate representation of merged trees):
3316 New test, from Joel E. Denny in:
3317 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
3318 * THANKS: Add Joel E. Denny.
3320 * configure.ac (AC_INIT): Bump to 2.0c.
3322 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
3324 * NEWS: Version 2.0b.
3326 * Makefile.am (SUBDIRS): Put examples before tests, so that
3327 "make check" doesn't finish with "All 1 tests passed".
3329 * tests/regression.at (Token definitions): Don't rely on
3330 AT_PARSER_CHECK for data that contains backslashes. It currently
3331 uses 'echo', and 'echo' isn't portable if its argument contains
3332 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
3333 that the byte '\0xff' is not printable in the C locale; it is,
3334 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
3335 not printable, so use '\0x81' to test.
3337 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
3338 version of GCC, since the macro is used with non-GCC compilers.
3340 Fix core dump reported by Pablo De Napoli in
3341 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
3342 * tests/regression.at (Invalid inputs with {}): New test.
3343 * src/parse-gram.y (token_name): Translate type before using
3346 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
3347 the user's name space. All uses changed to __attribute__
3349 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
3350 Add __attribute__ ((__noreturn__)).
3352 * etc/clcommit: Remove. We weren't using it, and it failed
3353 "make maintainer-distcheck".
3354 * Makefile.maint: Merge from coreutils.
3355 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
3356 (syntax-check-rules): Change list of rules as described below.
3357 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
3358 (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):
3359 (sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope):
3360 (sc_trailing_space): New rules.

3363 (sc_space_tab, sc_error_exit_success, sc_changelog):
3364 (sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
3365 (makefile-check, po-check, author_mark_check):
3366 (makefile_path_separator_check, copyright-check):
3367 Use grep -n, to make it easier to find violations.
3368 Use CVS_LIST and CVS_LIST_EXCEPT.
3369 (header_regexp, h_re): Remove.
3371 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
3372 (my-distcheck): Use more-modern GCC flags.
3373 (signatures, %.asc): Remove.
3374 (rel-files, announcement): Remove signatures.
3375 Restore old updating code, even though we don't use it, so
3376 that we're the same as coreutils.
3377 (alpha, beta, major): Depend on news-date-check.
3378 Make the upload commands.
3380 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
3381 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
3382 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
3383 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.
3384 * src/Makefile.am, src/gram.c, src/muscle_tab.h: Likewise.
3385 * src/parse-gram.y, src/system.h, src/tables.c, src/vcg.c: Likewise.
3386 * src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise.
3387 * tests/sets.at: Likewise.
3389 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
3390 we comment out the Autoconf version number.
3391 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
3392 it's error-prone and "make maintainer-distcheck" rejects it.
3394 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
3395 Indent calls to "error" to pacify "make maintainer-distcheck",
3396 when the calls are not intended to be translated.
3397 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
3399 * src/Makefile.am (DEFS): Use +=, to pacify
3400 "make maintainer-distcheck".
3401 (bison_SOURCES): Add scan-skel.h.
3402 (sc_tight_scope): New rule, from coreutils.
3404 * src/files.c (src_extension, header_extension):
3405 Now static, not extern.
3406 * src/getargs.c (short_options): Likewise.
3407 * src/muscle_tab.c (muscle_table): Likewise.
3408 * src/parse-gram.y (current_class, current_type, current_prec):
3410 * src/reader.c (grammar_end, previous_rule_end): Likewise.
3411 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
3412 * src/main.c (main): Cast bindtextdomain and textdomain calls to
3413 void, to avoid warning when NLS is disabled.
3414 * src/output.c: Include scan-skel.h.
3415 (scan_skel): Remove decl, since scan-skel.h does this.
3417 Indent calls to "error" to pacify "make maintainer-distcheck".
3418 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
3419 * src/reader.h (gram_end, gram_lineno): New decls to pacify
3420 "make maintainer-distcheck".
3421 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
3422 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
3423 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
3424 (skel_lex_destroy, scan_skel): Move these decls to...
3425 * src/scan-skel.h: New file.
3426 * src/uniqstr.c (uniqstr_assert):
3427 Indent calls to "error" to pacify "make maintainer-distcheck".
3429 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
3432 * tests/torture.at: Revamp to avoid misuse of atoi that
3433 "make maintainer-distcheck" complained about.
3435 * examples/extexi (message): Don't print a message more than once,
3436 and omit line-number decoration that makes Emacs compile think
3437 that informative messages are worth worrying about.
3439 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
3441 * configure.ac: Update version number.
3443 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
3445 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
3446 autogenerated by the maintainer.
3447 * examples/calc++/.cvsignore: Add *.yy.
3449 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
3450 * lib/bitset_stats.c (bitset_stats_init): Likewise.
3451 * lib/bitsetv.c (bitsetv_alloc): Likewise.
3453 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
3455 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
3456 from maintainer-distcheck about casting the argument of 'free'.
3458 * NEWS: Mention recent yytname changes.
3459 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
3461 * bootstrap: For translations that have not yet been upgraded to
3462 the new runtime-po domain, prime the pump by extracting the
3463 relevant strings from the obsolete translations. This code can be
3464 removed once the bison-runtime domain has been translated by each
3467 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
3468 now that token names are already quoted.
3470 Fix problem reported by Anthony Heading.
3471 * data/glr.c (YYTOKEN_TABLE): New macro.
3472 (yytname): Define if YYTOKEN_TABLE.
3473 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
3474 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
3475 (YYERROR_VERBOSE): Define the same way the other skeletons do.
3476 * src/output.c (prepare_symbols): Output token_table_flag.
3478 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
3480 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
3481 again if the first call fails.
3483 * data/glr.c (yytnamerr): New function.
3484 (yyreportSyntaxError): Use it to dequote most string literals.
3485 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
3486 with other skeletons. All uses changed.
3487 (yytnameerr_): New function.
3488 (yyreport_syntax_error): Use it to dequote most string literals.
3489 * data/yacc.c (yytnamerr): New function.
3490 (yyerrlab): Use it to decode most string literals.
3491 * doc/bison.texinfo (Decl Summary, Calling Convention):
3492 Clarify quoting convention of yytname.
3493 * src/output.c (prepare_symbols): Quote all names. This undoes
3494 the 2005-04-17 change, which is now accomplished (mostly) via
3495 changes in the parsers as described above.
3496 * tests/regression.at (Token definitions, Web2c Actions):
3497 Undo most 2005-04-17 change here, too.
3499 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
3501 Fix more problems reported by twlevo@xs4all.nl.
3502 * tests/cxx-type.at: Don't pipe output of ./types through sed to
3503 remove trailing spaces. This loses the exit status of ./types,
3504 and isn't needed since ./types shouldn't be emitting trailing
3506 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
3507 as the stack isn't valid in that case.
3509 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
3510 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
3511 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
3512 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
3514 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
3515 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
3516 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
3519 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
3520 overly-picky compilers that reject 'char *foo = "bar";'.
3522 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
3523 to FILE * parameter, not to stderr. This fixes a typo introduced
3524 in the 2005-07-12 change.
3526 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
3527 warnings from GCC 4.
3529 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
3530 (yyglrShiftDefer, yysplitStack):
3531 Remove unused parameters b4_pure_formals. All uses changed.
3532 (yyglrShift): Remove unused parameters b4_user_formals.
3534 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
3536 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
3538 Destructor cleanups and regularization among the three skeletons.
3539 * NEWS: Document the behavior changes.
3540 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
3541 stack before failing, as the cleanup code will do it for us now.
3542 * data/lalr1.cc (yyerrlab): Likewise.
3543 * data/glr.c (yyparse): Pop everything off the stack before
3544 freeing it, so that destructors get called properly.
3545 * data/lalr1.cc (yyreturn): Likewise.
3546 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
3547 This is more consistent.
3548 * doc/bison.texinfo (Destructor Decl): Mention more reasons
3549 why destructors might be called. 1.875 -> 2.1.
3550 (Destructor Decl, Decl Summary, Table of Symbols):
3551 Some English-language cleanups for %destructor.
3552 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
3553 Add output line for destructor of start symbol.
3554 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
3555 because of that same extra output line.
3557 * NEWS: Document minor wording changes in diagnostics of
3558 Bison-generated parsers.
3559 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
3560 Remove unused formals. All uses changed.
3561 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
3562 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
3563 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
3564 Rename yyoverflowab to yyexhaustedlab.
3565 When memory exhaustion occurs during syntax-error reporting,
3566 report it separately rather than in a single diagnostic; this
3568 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
3569 (Memory Exhausted): Renamed from Parser Stack Overflow.
3570 Revamp wording slightly to prefer "memory exhaustion".
3571 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
3573 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
3575 Add i18n support to the GLR skeleton. Partially fix the C++
3576 skeleton; a C++ expert needs to finish this. Remove debugging
3577 msgids; there's little point to having them translated, since they
3578 can be understood only by someone who can read the
3579 (English-language) source code.
3581 Generate runtime-po/bison-runtime.pot automatically, so that we
3582 don't have to worry about garbage getting in that file. We'll
3583 make sure after the next official release that old msgids don't
3585 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
3587 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
3589 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
3590 Fix typos in explanations of the runtime file.
3591 * bootstrap: Change gettext keyword from YYI18N to YY_.
3592 Use standard Makefile.in.in in runtime-po, since we'll arrange
3593 for backward-compatible bison-runtime.po files in a different way.
3594 * data/glr.c (YY_): New macro, from yacc.c.
3595 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
3596 Translate messages intended for users.
3597 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
3598 the wording in the other skeletons. We don't know that the memory
3600 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
3601 Use same method that yacc.c uses.
3602 Don't translate debugging messages.
3603 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
3604 it doesn't work (yet), and requires C++ expertise to fix.
3605 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
3606 Move defn to a more logical place, to be consistent with other
3608 Don't translate debugging messages.
3609 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
3610 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
3611 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
3612 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
3614 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
3615 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
3617 * tests/glr-regression.at (Badly Collapsed GLR States):
3619 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
3620 yylex should return 0 at EOF rather than aborting.
3622 Improve tests for stack overflow in GLR parser.
3623 Problem reported by twlevo@xs4all.nl.
3624 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
3626 (yyStackOverflow): Just longjmp, but with value 2 so that caller
3627 can handle the problem.
3628 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
3629 (yyparse): New local variable yyresult to record the result.
3630 Use result of setjmp to set it, rather than storing itinto
3632 (yyDone): Remove label.
3633 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
3634 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
3635 if YYABORT is used).
3636 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
3637 yyparse status; put status > 1 into diagnostic.
3638 Check that status==2 works.
3639 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
3640 Use exit status 3 for failure to open (which shouldn't happen).
3642 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
3644 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
3645 1 on syntax error; just let yyparse do its thing.
3646 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
3647 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
3648 (Exploding the Stack Size with Alloca):
3649 (Exploding the Stack Size with Malloc):
3650 Expect exit status 2, not 1, since the parser is supposed to blow
3651 its stack. Problem reported by twlevo@xs4all.nl.
3653 * data/glr.c (yyparse): Don't assume that the initial calls
3654 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
3655 Print a stack-overflow message and fail instead.
3656 Initialize the line-number information before creating the stack,
3657 so that the stack-overflow message can report line zero safely.
3659 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
3661 Fix problems reported by twlevo@xs4all.nl.
3662 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
3663 (yyuserMerge): Provide a default case if b4_mergers is empty.
3664 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
3665 * tests/glr-regression.at
3666 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
3667 Add casts to pacify C++ compilers.
3668 * tests/glr-regression.at (Improper merging of GLR delayed action
3669 sets): Declare yylex before using it.
3670 * tests/Makefile.am (maintainer-check-g++): Fix a stray
3671 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
3672 test for valgrind; valgrind is independent of g++.
3673 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
3674 for compatibility with POSIX 1003.1-2001 (if running coreutils).
3675 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
3676 Use a destructor, so that we can expand the stack. Change
3677 YYSTYPE to char * so that we can free it. Cast result of malloc.
3679 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
3681 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
3682 a valgrind failure. Problem reported by twlevo@xs4all.nl.
3684 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
3686 * PACKAGING: New file, suggested by Bruno Haible and taken from
3687 similar wording in gettext's PACKAGING file.
3688 * NEWS: Mention PACKAGING.
3689 * Makefile.am (EXTRA_DIST): Add PACKAGING.
3691 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
3693 * NEWS: Document recent i18n improvements.
3694 * bootstrap: Get runtime translations into runtime-po.
3695 Create runtime-po files automatically, if possible.
3696 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
3697 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
3698 does not infringe on the user's name space.
3699 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
3700 * doc/bison.texinfo (Internationalization): Revamp the English
3701 and Texinfo syntax a bit, to try to make it clearer.
3702 (Bison Options, Option Cross Key): Mention --print-localedir.
3703 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
3704 YYENABLE_NLS. Quote a bit more.
3705 * runtime-po/.cvsignore: New file.
3706 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
3707 * runtime-po/Rules-quot: Remove; now created by bootstrap.
3708 * runtime-po/quot.sed: Likewise.
3709 * runtime-po/boldquot.sed: Likewise.
3710 * runtime-po/en@quot.header: Likewise.
3711 * runtime-po/en@boldquot.header: Likewise.
3712 * runtime-po/insert-header.sin: Likewise.
3713 * runtime-po/remove-potcdate.sin: Likewise.
3714 * runtime-po/Makevars: Likewise.
3715 * runtime-po/LINGUAS: Likewise.
3716 * runtime-po/de.po: Likewise; we will rely on the translation project
3717 to maintain this, so "bootstrap" should get it.
3718 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
3720 * src/main.c (main): Bind the bison-runtime domain, too.
3722 2005-07-12 Bruno Haible <bruno@clisp.org>
3724 * data/yacc.c: Include <libintl.h> when NLS is enabled.
3725 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
3726 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
3727 * runtime-po: New directory.
3728 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
3729 $(DOMAIN).pot-update rule, so that old messages are never dropped.
3730 * runtime-po/Rules-quot: New file, copied from po/.
3731 * runtime-po/quot.sed: Likewise.
3732 * runtime-po/boldquot.sed: Likewise.
3733 * runtime-po/en@quot.header: Likewise.
3734 * runtime-po/en@boldquot.header: Likewise.
3735 * runtime-po/insert-header.sin: Likewise.
3736 * runtime-po/remove-potcdate.sin: Likewise.
3737 * runtime-po/Makevars: New file.
3738 * runtime-po/POTFILES.in: New file.
3739 * runtime-po/LINGUAS: New file.
3740 * runtime-po/bison-runtime.pot: New file.
3741 * runtime-po/de.po: New file.
3742 * m4/bison.m4: New file.
3743 * Makefile.am (SUBDIRS): Add runtime-po.
3744 (aclocaldir, aclocal_DATA): New variables.
3745 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
3747 * src/getargs.c (usage): Document --print-localedir option.
3748 (PRINT_LOCALEDIR_OPTION): New enum item.
3749 (long_options): Add --print-localedir option.
3750 (getargs): Handle --print-localedir option.
3751 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
3752 (Internationalization): New section.
3754 2005-07-12 Akim Demaille <akim@epita.fr>
3756 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
3757 for consistency with the rest of the code.
3758 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
3761 2005-07-12 Akim Demaille <akim@epita.fr>
3763 * src/parse-gram.y: Use %printer instead of YYPRINT.
3765 2005-07-12 Akim Demaille <akim@epita.fr>
3767 * src/symtab.h, src/symtab.c (symbol_print): New.
3768 * src/symlist.h, src/symlist.c (symbol_list_print): New.

3771 2005-07-12 Akim Demaille <akim@epita.fr>
3773 * data/glr.c (b4_syncline): Fix (swap) the definitions of
3774 b4_at_dollar and b4_dollar_dollar.
3776 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
3778 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
3779 and Pennello's paper.
3781 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
3783 * data/yacc.c (yyparse): Undo previous patch. Instead,
3784 set yylsp[0] and yyvsp[0] only if the initial action
3785 sets yylloc and yylval, respectively.
3787 * data/yacc.c (yyparse): In the initial action, set
3788 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
3789 This avoids the use of undefined variables if the initial
3790 action does not set yylloc and/or yylval.
3792 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
3794 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
3795 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
3796 Remove from CVS. These files are automatically generated.
3797 * examples/extexi: Clarify that this file is now part of Bison,
3798 not GNU M4, and that it works with any POSIX-compatible Awk.
3799 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
3800 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
3801 so that we also get calc++-parser.yy. Geneate it.
3802 Use $(AWK), not gawk, since any conforming Awk will do.
3803 Put comment before action, since older 'make' can't handle comment
3805 $(BUILT_SOURCES): List all built sources, not just some of them.
3806 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
3807 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
3808 $($(calc_sources_generated)): Remove unnecessary test for existence
3809 of target. (This had a shell syntax error anyway; a stray "x".)
3810 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
3812 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
3814 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
3815 implied by the other modules.
3817 2005-07-06 Akim Demaille <akim@epita.fr>
3819 Bind examples/calc++ to the package.
3820 * examples/calc++/Makefile: Remove, replaced by...

3822 * examples/calc++/test: Remove input.
3823 * examples/calc++/compile: Remove.
3824 * examples/Makefile.am: New.
3825 * configure.ac, Makefile.am: Adjust.
3826 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
3828 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
3830 * data/glr.c (yyFail): Drastically simplify; since the format argument
3831 never had any % directives, we can simply pass it to yyerror.
3832 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
3833 be modified later, as that is the usual style in glr.c.
3834 Problems reported by Paul Hilfinger.
3836 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
3837 and size overflow errors.
3838 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
3839 in case the user prolog sets feature-test macros like _GNU_SOURCE.
3840 (YYSIZEMAX): New macro.
3841 (yystpcpy): New function, taken from yacc.c.
3842 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
3843 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
3844 so that we don't have to maintain their signatures.
3845 (yyFail): Check for buffer overflow, by using vsnprintf rather
3846 than vsprintf. Allocate a bigger buffer if possible.
3847 Report an error if buffer allocation fails.
3848 (yyStackOverflow): New function.
3849 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
3850 the initialization was successful. It might fail if storage was
3852 (yyexpandGLRStack): Add more checks for storage allocation failure.
3853 Use yyStackOverflow to report failures.
3854 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
3855 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
3856 Don't assume stack number fits in int.
3857 (yysplitStack): Check for storage allocation failure.
3858 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
3859 can print diagnostics on storage allocation failure. All callers
3861 (yyresolveValue): Use yybool for boolean.
3862 (yyreportSyntaxError): Check for size-calculation overflow.
3863 This code is taken from yacc.c.
3864 (yyparse): Check for storage allocation errors when allocating
3867 2005-07-05 Akim Demaille <akim@epita.fr>
3869 Extract calc++ from the documentation.
3870 * doc/bison.texinfo (Calc++): Add the extraction marks.
3871 * examples/extexi: New, from the aborted GNU Programming 2E.
3872 Separate the different paragraph of a file with empty lines.
3873 * examples/Makefile: Use it to extract the whole calc++ example.
3875 2005-06-24 Akim Demaille <akim@epita.fr>
3877 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
3880 2005-06-22 Akim Demaille <akim@epita.fr>
3882 * doc/bison.texinfo (C++ Language Interface): First stab.
3883 (C++ Parsers): Remove.
3885 2005-06-22 Akim Demaille <akim@epita.fr>
3887 * data/lalr1.cc (yylex_): Honor %lex-param.
3889 2005-06-22 Akim Demaille <akim@epita.fr>
3891 Start a set of simple examples.

3894 * examples/calc++/calc++-parser.yy,
3895 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
3896 * examples/calc++/compile, examples/calc++/test: New.
3898 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
3900 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
3901 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
3902 which stems from the 2005-05-27 patch.
3904 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
3906 * data/glr.c: Modify treatment of unused parameters to permit use
3907 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
3909 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
3911 Fix infringement on user name space reported by Janos Zoltan Szabo.
3912 * data/yacc.c (yyparse): strlen -> yystrlen.
3914 2005-05-30 Akim Demaille <akim@epita.fr>
3916 * data/lalr1.cc (_): New.
3917 Translate the various messages.
3919 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
3921 Fix infringement on user name space reported by Bruno Haible.
3922 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
3923 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
3924 the user's name space.
3925 (alloca): Include <stdlib.h> to get it, if it's not built in.
3926 (YYMALLOC, YYFREE): Define only if needed.
3927 (malloc, free): Declare, but only if needed, as this infringes on
3928 the user name space.
3930 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
3932 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
3933 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
3935 * lib/ebitset.c (min, max): Undef before defining.
3936 * lib/vbitset.c (min, max): Likewise.
3937 * lib/subpipe.c (create_subpipe): Save local variables in case
3938 vfork clobbers them.
3940 2005-05-24 Bruno Haible <bruno@clisp.org>
3942 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
3943 error message syntax used by gcc-4.0.
3945 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
3947 * README: Mention m4 1.4.3. Remove obsolete advice about
3948 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
3950 * bootstrap: Remove workaround for problem I encountered with
3951 gettext 0.14.1; it seems to be fixed now.
3953 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
3955 * NEWS: Version 2.0a.
3957 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
3958 the previous change.
3960 Various maintainer cleanups.
3961 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
3962 conftest*, for benefit of CVS commands run at the same time as
3963 "configure". Add build-aux, since "bootstrap" now creates it and
3965 * Makefile.cfg (move_if_change): Remove.
3966 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
3967 (ftp-gnu, www-gnu, move_if_change, local_updates, update):

3972 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
3974 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
3975 this is now the recommended name.
3976 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
3977 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
3978 ylwrap. These files now go into build-aux.
3979 * config/move-if-change: Remove.
3980 * config/prev-version.txt: Bump from 1.75 to 2.0.
3982 * bootstrap: Add stdio-safer, unistd-safer modules.
3983 Remove m4/glibc2.m4 (introduced by latest gnulib, but
3985 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
3986 fopen-safer.c, stdio-safer.h, unistd-safer.h.
3987 * lib/subpipe.c: Include "unistd-safer.h".
3988 (create_subpipe): Make sure all the newly-created
3989 file descriptors are > 2, so that diagnostics don't
3990 get sent down them (which might cause Bison to hang, in theory).
3991 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
3992 * src/files.c (xfopen): Use fopen_safer, not fopen.
3994 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
3995 yesterday's yacc.c fix.
3997 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>

4001 Fix a destructor bug reported by Wolfgang Spraul in
4002 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
4003 * data/yacc.c (yyabortlab): Don't call destructor, and
4004 don't set yychar to EMPTY.
4005 (yyoverflowlab): Don't call destructor.
4006 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
4007 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
4008 since we no longer output the message "discarding lookahead token
4011 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
4013 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
4014 fix a small glitch in debugging output.
4015 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
4016 after YY_SYMBOL_PRINT where needed.
4018 (struct yyGLRState): Add some comments.
4019 (struct yySemanticOption): Add some comments.
4020 (union yyGLRStackItem): Add comment.
4022 (yymergeOptionSets): Correct this to properly perform the union,
4023 avoiding infinite reported by Michael Rosien.

4067 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
4069 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
4070 Problem reported by Ralf Menzel.
4072 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
4074 * tests/actions.at: Test that stack overflow invokes destructors.
4075 From Marcus Holland-Moritz.
4076 * data/yacc.c (yyerrlab): Move the code that destroys the stack
4078 (yyreturn): to here. That way, destructors are called properly
4079 even if the stack overflows, or the user calls YYACCEPT or
4080 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
4081 (yyoverflowlab): Destroy the lookahead.
4083 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
4085 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
4087 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
4089 * NEWS: Bison-generated C parsers no longer quote literal strings
4090 associated with tokens.
4091 * src/output.c (prepare_symbols): Don't escape strings,
4092 since users don't want to see C escapes.
4093 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
4095 * tests/input.at (Torturing the Scanner): Likewise.
4096 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
4098 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
4100 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
4101 the data size is known to be too small and we can't increase it.
4102 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
4104 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
4106 * src/parse-gram.y: Include quotearg.h.
4107 (string_as_id): Quote $1 before using it as a key, since the
4108 lexer no longer quotes it for us.
4109 (string_content): Don't strip quotes, since lexer no longer
4111 * src/scan-gram.l: Include quotearg.h.
4113 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
4114 a key, since the rest of the lexer doesn't quote it.
4115 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
4116 * tests/regression.at (Token definitions): Check for backslashes
4119 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
4120 (YYSIZE_T): Define to unsigned long int when using an older compiler.
4121 (yyparse): Revamp code to generate long syntax error message, to
4122 make it easier to translate, and to avoid problems with arithmetic
4123 overflow. Change "virtual memory" to "memory" in diagnostic, since
4124 we don't know whether the memory is virtual.
4126 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
4128 * NEWS: Bison-generated C parsers now use the _ macro to
4130 * data/yacc.c (_) [!defined _]: New macro.
4131 All English strings wrapped inside this macro.
4132 * doc/bison.texinfo (Bison Parser): Document _.
4133 * po/POTFILES.in: Include src/parse-gram.c, since it now
4134 includes translateable strings that parse-gram.y doesn't.
4136 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
4138 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
4139 reverting the 2004-10-11 change to this function.
4140 (symbol_check_alias_consistency): Don't call symbol_type_set
4141 if the type name is already correct.
4142 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
4144 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
4146 * tests/regression.at (Token definitions): Don't use a token named
4147 c, as that generates a "#define c ..." that runs afoul of buggy
4148 stdlib.h that uses the identifier c as a member of struct
4149 drand48_data. Problem reported by Horst Wente.
4151 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
4153 * bootstrap: Change translation URL from
4154 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
4155 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
4156 redirection glitches. Problem reported by twlevo@xs4all.nl.
4158 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
4160 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
4161 after operands; POSIX says this isn't portable for the c99 command.
4163 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
4165 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
4166 immediately if a data overrun has occurred; this may help us track
4167 down what may be a spurious failure on MacOS.
4169 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
4171 Respond to problems reported by twlevo@xs4all.nl.
4173 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
4175 * src/vcg.h: Comment fix.
4176 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
4177 (G_CMAX): Change to -1 instead of INT_MAX.
4179 * data/yacc.c (yyparse): Omit spaces before #line.
4181 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
4183 * src/tables.c (state_number_to_vector_number): Put it inside an
4184 "#if 0", since it's not currently used. Problem reported by
4187 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
4189 * src/output.c (escaped_output): Renamed from
4190 escaped_file_name_output, since we now use it for symbol tags as
4191 well. All uses changed.
4192 (symbol_destructors_output, symbol_printers_output):
4193 Escape symbol tags too.
4194 Problem reported by Matyas Forstner in
4195 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
4197 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
4199 * src/output.c (user_actions_output, token_definitions_output,
4200 symbol_destructors_output, symbol_printers_output): Likewise.
4201 * src/reader.c (prologue_augment): Likewise.
4202 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
4204 * src/vcg.c (output_edge): Don't quote linestyle arg.
4205 Problem reported by twlevo@xs4all.nl.
4207 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
4209 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
4210 example, reported by Derek M Jones. Also, make the example even
4211 more outrageous, to better illustrate how bad the problem is.
4213 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
4215 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
4216 putsym. Typo reported by Sebastian Piping.
4218 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4220 * doc/bison.texinfo (Language and Grammar): some -> same
4221 (Epilogue): int he -> in the
4222 Typos reported by Sebastian Piping via Justin Pence.
4224 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
4226 * tests/glr-regression.at (Improper handling of embedded actions
4227 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
4228 embedded actions and $-N in GLR parsers", work around an Autoconf bug
4229 with dollar signs in test names.
4230 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
4231 for a similar reason.
4233 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
4235 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
4236 wants to redefine G_VIEW.
4238 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
4240 * src/vcg.c (get_view_str): Remove case for normal_view.
4241 Problem reported by twlevo@xs4all.nl.
4243 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
4245 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
4246 Problem reported by twlevo@xs4all.nl.
4248 * doc/bison.texinfo: Change @dircategory from "GNU programming
4249 tools" to "Software development". Requested by Richard Stallman
4252 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
4254 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
4255 Problem reported by twlevo@xs4all.nl.
4257 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
4259 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
4260 keyword; it's not needed with modern compilers, and it doesn't
4261 affect correctness with older compilers. Suggested by
4264 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
4266 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
4267 gcc -Wswitch-default.
4268 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
4269 * data/yacc.c (yyparse): Likewise.
4271 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
4273 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
4274 already. Let config.h define any nonstandard values.
4276 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
4278 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
4279 for the benefit of slower hosts. Problem reported by
4282 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
4284 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
4285 being defined and not used.
4286 * data/lalr1.cc (yyparse): Likewise.
4287 Use "if (false)" rather than "if (0)".
4289 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
4291 * TODO: Mention that we should allow NUL bytes in tokens.
4293 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
4295 * src/scan-skel.l (<<EOF>>): Don't close standard output.
4296 Problem reported by Hans Aberg.
4298 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
4300 * src/getargs.c (version): Happy new year; update overall
4301 program copyright date from 2004 to 2005.
4303 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
4304 Problem reported by Hans Aberg.
4305 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
4306 (Output file names.): Add a test for the case when standard output
4309 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
4311 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
4312 to fix an oversight in the Bison 2.0 manual.
4314 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
4316 * NEWS: Version 2.0. Reformat the existing news items since
4317 1.875, so that related items are grouped together.
4318 * configure.ac (AC_INIT): Bump version to 2.0.
4319 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
4321 * tests/torture.at (Exploding the Stack Size with Alloca): Set
4322 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
4323 otherwise, we're not testing alloca. Unfortunately there's no
4324 simple way to consult HAVE_ALLOCA here.
4326 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
4329 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
4330 hand. This avoids a warning about comparing int to size_t when
4331 GCC warnings are enabled.
4333 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
4335 * NEWS: Bison-generated parsers no longer default to using the
4336 alloca function (when available) to extend the parser stack, due
4337 to widespread problems in unchecked stack-overflow detection.
4338 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
4339 responsibility to set it to a positive value. This lets the user
4340 specify a value that is not a preprocessor constant.
4341 * data/yacc.c (YYMAXDEPTH): Likewise.
4342 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
4343 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
4344 to be a compile-time constant. However, explain the constraints on it.
4345 Also, explain the constraints on YYINITDEPTH.
4346 (Table of Symbols): Explain that alloca is no longer the default.
4347 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
4350 * doc/bison.texinfo (Location Default Action): Mention that n must
4351 be zero when k is zero. Suggested by Frank Heckenbach.
4353 2004-12-22 Akim Demaille <akim@epita.fr>
4355 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
4356 (parser::state_type, parser::semantic_type, parser::location_type):
4357 Private, not public.
4358 (parser::parse): Return ints, not bool.
4359 Returning a bool introduces a problem: 0 corresponds to false, and
4360 it seems weird to return false on success. Returning true changes
4361 the conventions for yyparse.
4362 Alternatively we could return void and send an exception.
4363 There is no clear consensus (yet?).
4364 (state_stack, semantic_stack, location_stack): Rename as...
4365 (state_stack_type, semantic_stack_type, location_stack_type): these.
4366 Private, not public.
4367 * tests/c++.at: New.
4368 * tests/testsuite.at, tests/Makefile.am: Adjust.
4370 2004-12-21 Akim Demaille <akim@epita.fr>
4372 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
4374 2004-12-21 Akim Demaille <akim@epita.fr>
4376 Don't impose std::string for filenames.
4378 * data/lalr1.cc (b4_filename_type): New.
4379 (position::filename): Use it.
4380 (parser.hh): Move the inclusion of stack.hh and location.hh below
4381 the user code, so that needed headers for the filename type can be
4383 Forward declare them before the user code.
4384 * tests/Makefile.am (check-local, installcheck-local): Pass
4385 TESTSUITEFLAGS to the TESTSUITE.
4387 2004-12-20 Akim Demaille <akim@epita.fr>
4389 Use more STL like names: my_class instead of MyClass.
4391 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
4392 (SemanticStack, SemanticType, StateStack, StateType)
4393 (TokenNumberType, Stack, Slice, Traits, Parser::location)
4394 (Parser::value): Rename as...
4395 (location_stack, location_type, rhs_number_type, semantic_stack)
4396 (semantic_type, state_stack, state_type, token_number_type, stack)
4397 (slice, traits, parser::yylloc, parser::yylval): these.
4399 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
4401 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
4403 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
4404 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
4406 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
4408 Remove uses of 'short int' and 'unsigned short int'. This raises
4409 some arbitrary limits. It uses more memory but nowadays that's
4410 not much of an issue.
4412 This change does not affect the generated parsers; that's a different
4413 task, as some users will want to conserve memory there.
4415 Ideally we should use size_t to represent all object counts, and
4416 something like ptrdiff_t to represent signed differences of object
4417 counts; but that will require more code-cleanup than I have the
4418 time to do right now.
4420 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
4421 Use size_t, not int or short int, to count objects.
4422 * src/closure.c (nritemset, closure): Likewise.
4423 * src/closure.h (nritemset, closure): Likewise.
4424 * src/nullable.c (nullable_compute): Likewise.
4425 * src/print.c (print_core): Likewise.
4426 * src/print_graph.c (print_core): Likewise.

4428 * src/state.h (struct state): Likewise.
4429 * src/tables.c (default_goto, goto_actions): Likewise.
4431 * src/gram.h (rule_number, rule): Use int, not short int.
4432 * src/output.c (prepare_rules): Likewise.
4433 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
4434 errs, reductions): Likewise.
4435 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
4437 * src/tables.c (vector_number, tally, action_number,
4438 ACTION_NUMBER_MINIMUM): Likewise.
4439 * src/output.c (muscle_insert_short_int_table): Remove.
4441 2004-12-17 Akim Demaille <akim@epita.fr>
4443 * data/lalr1.cc: Extensive Doxygenation.
4444 (error_): Rename as...
4445 (error): this, since it is visible to the user.
4447 (Parser::message): Now an automatic variable from...
4448 (Parser::yyreport_syntax_error_): here.
4449 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
4451 * tests/input.at: Escape $.
4453 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
4455 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
4456 Parenthesize rhs to avoid obscure problems with mistakes like
4457 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
4458 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
4459 b4_rhs_location): Likewise.
4460 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
4461 b4_rhs_location): Likewise.
4463 2004-12-16 Akim Demaille <akim@epita.fr>
4465 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
4466 yacc.c: be sure to stay within yycheck_.
4467 * tests/actions.at: Re-enable C++ tests.
4469 2004-12-16 Akim Demaille <akim@epita.fr>
4471 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
4474 2004-12-16 Akim Demaille <akim@epita.fr>
4476 Use #define to handle the %name-prefix.
4478 * data/glr.c, data/yacc.c: Comment changes.
4479 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
4480 so that one can refer to yylex in the parser file, and have it
4481 renamed, as is the case with other skeletons.
4483 2004-12-16 Akim Demaille <akim@epita.fr>
4485 Move lalr1.cc internals into yy*.

4505 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
4507 Fix some problems reported by twlevo at xs4all.
4508 * src/symtab.c (symbol_new): Report an error if the input grammar
4509 contains too many symbols. This is better than calling abort() later.
4510 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
4511 (struct node, struct graph):
4512 Rename member expand to stretch. All uses changed.
4513 (struct graph): Remove member layoutalgorithm. All uses removed.
4514 * src/vcg.c (get_layoutalgorithm_str): Remove. All uses removed.
4515 * src/vcg_defaults.h (G_STRETCH): Renamed from G_EXPAND.
4517 (N_STRETCH): Rename from N_EXPAND. All uses changed.
4519 2004-12-15 Akim Demaille <akim@epita.fr>
4521 * data/lalr1.cc: Normalize /** \brief ... */ to ///.
4522 Add more Doxygen comments.
4523 (symprint_, stack_print_, reduce_print_, destruct_, pop)
4524 (report_syntax_error_, translate_): Rename as...
4525 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
4526 (yypop_, yyreport_syntax_error_, yytranslate_): this.
4528 2004-12-15 Akim Demaille <akim@epita.fr>
4530 * data/lalr1.cc (lex_): Rename as...
4532 Move the trace here.
4533 Take the %name-prefix into account.
4534 Reported by Alexandre Duret-Lutz.
4536 2004-12-15 Akim Demaille <akim@epita.fr>
4538 Simplify the C++ parser constructor.
4540 * data/lalr1.cc (debug_): Rename as...
4541 (yydebug_): so that the parser's internals are always in the yy*
4544 (b4_parse_param_decl): Remove the leading comma as it is now only
4545 called as unique argument list.
4546 (Parser::Parser): Remove the constructor accepting a location and
4547 an initial debugging level.
4548 Remove from the other ctor the argument for the debugging level.
4549 (debug_level_type, debug_level, set_debug_level): New.
4551 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
4554 2004-12-15 Akim Demaille <akim@epita.fr>
4556 Remove b4_root related material: failure experiment
4557 (which goal was to allow to derive from a class).
4559 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
4560 definitions and uses.
4562 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
4564 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
4565 not 2, since it's not portable to subtract 1 from the start of an
4566 array. The new item 0 is never set or used. All uses changed.
4568 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
4569 the default definition of YYLLOC_DEFAULT. Problem reported
4570 by Frank Heckenbach.
4572 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
4574 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
4575 the normal case and one for the error case. Just use the
4576 first one uniformly. Problem reported by Frank Heckenbach.
4577 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
4578 use exactly the same macro in both places.
4579 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
4580 so that the normal-case YYRHSLOC works for the error case too.
4582 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
4583 (YYLLOC_DEFAULT): Use the same macro as glr.c.
4584 * doc/bison.texinfo (Location Default Action): Don't claim that
4585 we have an array of locations. Use the same macro for both glr
4586 and lalr parsers. Mention YYRHSLOC. Mention what happens when
4589 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
4591 * HACKING: Update email addresses to send announcements to.
4593 * configure.ac (AC_INIT): Bump version to 1.875f.
4595 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
4597 * NEWS: Version 1.875e.
4598 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
4600 * src/scan-skel.l: Include "complain.h", for "fatal".
4602 * src/relation.h (relation_print, relation_digraph):
4603 Relation sizes are of type relation_node, not size_t (this is
4604 merely a doc fix, since the two types are equivalent).
4605 (relation_transpose): Relation sizes are of type relation_node,
4607 * src/relation.c: Likewise.
4608 (top, infinity): Now of type relation_node, not int.
4609 (traverse, relation_transpose): Use relation_node, not int.
4611 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
4612 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
4613 (yyparse): Remove unused local introduced in 2004-10-25 patch.
4615 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
4616 specifying whether the test should be skipped. Use it tp
4617 specify that the [%defines %skeleton "lalr1.cc"] tests currently
4618 fail on some hosts, and should be skipped.
4620 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
4622 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
4623 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
4624 unless otherwise specified below.
4626 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
4627 to allocate kernel_base, kernel_items, kernel_size, since
4628 they needn't be initialized to 0.
4629 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
4630 * src/closure.c (new_closure): Likewise, for itemset.
4631 * src/derives.c (derives_compute): Likewise, for delts, derives, q.

4643 (token_actions): Likewise for yydefact, actrow, conflrow,
4645 (save_column): Likewise for froms[symno], tos[symno].
4646 (goto_actions): Likewise for state_count.
4647 (pack_table): Likewise for base, pos, check.
4648 (tables_generate): Likewise for width.
4650 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
4651 for initial core. Just have a separate core, so we needn't worry
4652 about whether kernel_size and kernel_base are initialized.
4654 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
4655 kernel_size, kernel_items): Remove unnecessary initialization.
4656 * src/conflicts.c (conflicts): Likewise.
4657 * src/derives.c (derives): Likewise.
4658 * src/muscle_tablc (muscle_insert): Likewise.

4660 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
4661 conflrow, conflict_table, conflict_list, table, check):
4664 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
4665 This is because all callers pass unsigned int.
4666 * src/closure.h (new_closure): Likewise.
4668 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
4669 (build_relations): Initialize includes[i] in all cases.
4670 * src/reader.c (packgram): Always initialize rules[ruleno].prec
4671 and rules[ruleno].precsym. Initialize members in order.
4672 * src/relation.c (relation_transpose): Always initialize new_R[i]
4674 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
4676 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
4677 conflict_list[0] was always 0, but now it isn't initialized.
4679 * src/table.c (table_grow): When conflict_table grew, the grown
4680 area wasn't cleared. Fix this.
4682 * lib/.cvsignore: Add strdup.c, strdup.h.
4683 * m4/.cvsignore: Add strdup.m4.
4685 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
4687 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
4688 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
4689 GOTO_NUMBER_MAXIMUM, since we occasionally compute
4690 ngotos + 1 without checking for overflow.
4691 (build_relations): Use END_NODE, not -1, to denote end of edges.
4692 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
4693 build_relations): Use goto_number, not int, for goto numbers.
4694 * src/tables.c (save_column, default_goto): Likewise.
4696 2004-11-23 Akim Demaille <akim@epita.fr>
4698 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
4699 of #defining from yystype.
4700 Don't typedef yystype, C++ does not need it.
4701 This lets it possible to forward declare it as union.
4703 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
4705 * bootstrap (gnulib_modules): Add extensions.
4706 Problem reported by Jim Meyering.
4708 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
4710 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
4711 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
4712 src/system.h, src/tables.c: XFREE -> free, to accommodate
4713 recent change to gnulib xalloc.h.
4714 Problem reported by Jim Meyering.
4716 2004-11-17 Akim Demaille <akim@epita.fr>
4718 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
4720 2004-11-17 Akim Demaille <akim@epita.fr>,
4721 Alexandre Duret-Lutz <adl@gnu.org>
4723 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
4726 Use it instead of cdebug_.
4727 (Parser::debug_stream, Parser::set_debug_stream): New.
4728 (Parser::symprint_): Define cdebug_ for temporary backward
4730 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
4733 2004-11-17 Akim Demaille <akim@epita.fr>
4735 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
4736 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
4737 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
4738 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
4740 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
4742 * data/glr.c (yyloc_default): Remove; not used.
4743 Problem reported by Frank Heckenbach.
4745 2004-10-25 Akim Demaille <akim@epita.fr>
4747 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
4748 Introduce another definition to address simple location arrays.
4749 (yyGLRStack): New member: yyerror_range.
4750 (yyrecoverSyntaxError, yyparse): Update it.
4751 (yyrecoverSyntaxError): Use it when shifting the error token to
4752 have an accurate range, equivalent to the one computed by both
4753 yacc.c and lalr1.cc.
4754 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
4755 that column numbers start at column 0, as per GNU Coding
4756 Standards, the others tests, and the doc.
4757 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
4758 Adjust to the above change (first column is 0).
4759 And adjust the location of the "<error>", now covering the whole
4762 2004-10-22 Akim Demaille <akim@epita.fr>
4763 and Paul Eggert <eggert@cs.ucla.edu>
4765 Remove some arbitrary limits on goto numbers and relations.
4766 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
4767 initial values, since they're never used.
4768 (set_goto_map): ngotos is now unsigned, so test for overflow
4769 by seeing whether it wraps around to zero.
4770 * src/lalr.h (goto_number): Now size_t, not short int.
4771 (GOTO_NUMBER_MAXIMUM): Remove.
4772 * src/relation.c (relation_print, traverse, relation_transpose):
4773 Check for END_NODE rather than looking at sign.
4774 * src/relation.h (END_NODE): New macro.
4775 (relation_node): Now size_t, not short int.
4777 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
4779 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
4780 keyword, not an identifier. Problem reported by Baron Schwartz in
4781 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
4783 2004-10-11 Akim Demaille <akim@epita.fr>
4785 * src/symtab.c (symbol_check_alias_consistency): Also check
4786 type names, destructors, and printers.
4787 Reported by Alexandre Duret-Lutz.
4788 Recode the handling of associativity and precedence in terms
4789 of symbol_precedence_set.
4790 Accept no redeclaration at all, not even equal to the previous
4792 (redeclaration): New.
4793 Use it to factor redeclaration complaints.
4794 (symbol_make_alias): Don't set the type of the alias, let
4795 symbol_check_alias_consistency do it as for other features.
4796 * src/symtab.h (symbol): Add new member prec_location, and
4798 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
4799 * tests/input.at (Incompatible Aliases): New.
4801 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
4803 .cvsignore fixes to accommodate gnulib changes,
4804 and the practice of naming build directories "_build".
4805 * .cvsignore: Add "_*". Sort.
4806 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
4807 * m4/.cvsignore: Add "*_gl.m4".
4809 2004-10-06 Akim Demaille <akim@epita.fr>
4811 * src/parse-gram.y (add_param): Fix the truncation of trailing
4814 2004-10-05 Akim Demaille <akim@epita.fr>
4816 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
4817 whether the reducion was empty or not. This leaves room to
4818 improve the use of YYLLOC_DEFAULT in such a case.
4819 lalr1.cc is still experimental, so changing this is acceptable.
4820 And finally, there are probably not many users who changed the
4821 handling of locations in GLR, so changing is admissible too.
4823 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
4824 empty reduction, set @$ to an empty location ending the previously
4826 Adjust uses to make sure the code is triggered on empty
4828 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
4829 expected output: empty reductions have empty locations.
4831 2004-09-29 Akim Demaille <akim@epita.fr>
4833 * data/lalr1.cc: Move towards a more standard C++ coding style
4834 for templates: Class < T > -> Class<T>.
4836 2004-09-29 Akim Demaille <akim@epita.fr>
4838 * data/lalr1.cc: Reinstall the former ctor, for sake of
4839 compatibility, but warn it will be removed.
4840 Move towards a more standard C++ coding style (i.e., type *var ->
4843 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
4845 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
4846 since it's less likely to work if NULs are involved in the future.
4848 2004-09-27 Akim Demaille <akim@epita.fr>
4850 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
4852 2004-09-27 Akim Demaille <akim@epita.fr>
4854 * data/lalr1.cc (b4_parse_param_decl_1): New.
4855 (b4_parse_param_decl): Use it to have different names between attribute
4857 (b4_cc_constructor_call): Likewise.
4859 2004-09-24 Akim Demaille <akim@epita.fr>
4861 * src/parse-gram.y (add_param): Strip the leading and trailing
4862 blanks from a formal argument declaration.
4863 (YY_LOCATION_PRINT): New.
4865 2004-09-24 Akim Demaille <akim@epita.fr>
4867 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
4870 2004-09-24 Akim Demaille <akim@epita.fr>
4872 * doc/bison.texinfo (Table of Symbols): Sort.
4874 2004-09-21 Akim Demaille <akim@epita.fr>
4876 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
4877 the useless parentheses.
4878 Suggested by Paul Eggert.
4880 2004-09-20 Akim Demaille <akim@epita.fr>
4882 Let the initial-action act on the look-ahead, and use it for the
4883 "initial push" (corresponding to an hypothetical beginning-of-file).
4884 And let lalr1.cc honor %initial-action.
4886 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
4888 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
4889 (Parser::Parser): Remove the ctor that used to initialize it.
4890 (Parser::parse): Like in the other skeletons, issue the "starting
4891 parse" message before any action.
4892 Honor %initial-action.
4893 Initialize the stacks with the lookahead.
4894 * data/yacc.c: Let $$ and @$ in %initial-action designate the
4896 Push them in the stacks.
4897 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
4899 2004-09-20 Akim Demaille <akim@epita.fr>
4901 * doc/bison.texinfo (Initial Action Decl): New.
4903 2004-09-20 Akim Demaille <akim@epita.fr>
4905 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
4906 clearer criterion to define it.
4907 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
4908 When reducing on an empty RHS, use the latest stacked location as
4910 yylloc is not always available.
4911 * data/glr.c: Likewise.
4912 Also, honor initial-actions.
4914 2004-09-20 Akim Demaille <akim@epita.fr>
4916 * data/yacc.c (YY_LOCATION_PRINT): New.
4917 Define when we know YYLTYPE's structure, i.e., when the default
4918 YYLLOC_DEFAULT is used.
4919 * data/c.m4 (b4_yysymprint_generate): Use it.
4920 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
4921 value of the result.
4922 (error_start_): Replace with...
4923 (error_range_): this location array.
4924 This allows to replace code relying on the implementation of
4925 locations by portable code.
4926 * data/yacc.c (yylerrsp): Replace with...
4927 (yyerror_range): this.
4928 Every time a token is popped, update yyerror_range[0], to have an
4929 accurate location for the error token.
4930 * data/glr.c (YY_LOCATION_PRINT): New.
4931 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
4932 deference a pointer.
4933 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
4934 report the location in %printers.
4936 * src/scan-skel.l: Instead of abort, report error messages to ease
4937 understanding skeleton scanning failures.
4939 2004-09-16 Akim Demaille <akim@epita.fr>
4941 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
4942 (iterator, const_iterator): these, to be more in the C++ spirit.
4943 Also, return reverse iterators so that when displaying the stack
4944 we display its bottom first.
4945 (Parser::stack_print_, Parser::reduce_print_): Match the messages
4947 We should probably use vector here though.
4949 2004-09-16 Akim Demaille <akim@epita.fr>
4951 Have more complete shift traces.
4953 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
4954 to report Shifts instead of ad hoc YYDPRINTF invocations,
4955 including for the error token.
4956 * data/lalr1.cc (symprint_): Output the location.
4957 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
4958 output the location within the %printer.
4959 Activate GLR tests, at least to make sure they compile properly.
4960 They still don't pass though.
4961 * tests/calc.at: Adjust expect verbose output, since now "Entering
4962 state..." is on a different line than the "Shifting" message.
4964 2004-09-08 Akim Demaille <akim@epita.fr>
4966 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
4967 Bison directive from the Bison file to the invocation of this
4968 macro, so that these directives are passed to
4969 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
4970 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
4971 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
4972 the extra Bison directives instead of the whole series.
4973 Change the grammar so that there are recoverable errors, and
4974 unrecoverable errors. Now we can have the parser give up before
4975 consuming the whole input. As a result we now can observe that
4976 the lookahead is freed when needed.
4977 Change the parser source to parse argv[1] instead of a hard coded
4979 Simplify yylex, and give a value and location to EOF.
4980 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
4981 passed directives already coded in the file.
4982 Add some tests to check the location of "error".
4983 For some tests, the C++ parser is correct, and not yacc.c.
4984 For other tests, they provide different, but unsatisfying, values,
4985 so keep the C++ value so that at least one parser is "correct"
4986 according to the test suite.
4987 (Actions after errors): Remove, this is subsumed by the
4988 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
4990 2004-09-06 Akim Demaille <akim@epita.fr>
4992 * data/lalr1.cc: Adjust the indentation of the labels.
4996 2004-09-06 Akim Demaille <akim@epita.fr>
4998 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
4999 argument, an informative message.
5000 Call YY_SYMBOL_PRINT.
5001 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
5002 * data/lalr1.cc (destruct_): Likewise.
5003 In addition, no longer depend on b4_yysymprint_generate and
5004 b4_yydestruct_generate to generate these functions, do it "by
5007 2004-09-03 Akim Demaille <akim@epita.fr>
5009 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
5010 invoked, yydestruct the lookahead.
5011 * tests/calc.at (Calculator $1): Update the expected lengths of
5012 traces: there is an added line for the discarded lookahead.
5013 * doc/bison.texinfo (Destructor Decl): Some rewording.
5014 Define "discarded" symbols.
5016 2004-09-02 Akim Demaille <akim@epita.fr>
5018 * data/lalr1.cc (translate_, destruct_): No reason to be static.
5020 2004-09-02 Akim Demaille <akim@epita.fr>
5022 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
5023 (YYDSYMPRINTF): Rename as...
5024 (YY_SYMBOL_PRINT): this.
5025 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
5027 Use it instead of direct symprint_ calls.
5028 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
5031 2004-09-02 Akim Demaille <akim@epita.fr>
5033 * data/lalr1.cc (b4_yysymprint_generate): New.
5034 (symprint_): New member function, defined when YYDEBUG.
5035 Use it consistently instead of token/nterm debugging output by
5037 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
5038 %printer calls to use cdebug_ when using lalr1.cc.
5040 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
5042 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
5043 with #ifdef YYDEBUG.
5045 2004-08-26 Akim Demaille <akim@epita.fr>
5047 * doc/bison.texinfo (Implementing Loops): Rename as...
5048 (Implementing Gotos/Loops): this.
5050 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
5052 Adjust to latest gnulib.
5053 * bootstrap (gnulib_modules): Add xalloc-die.
5054 Set LC_ALL=C so that file names sort consistently.
5055 Prefer the gnulib copies of gettext.m4, glibc21.m4,
5056 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
5057 uintmax_t.m4, ulonglong.m4.
5058 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
5059 po.m4 since we are now using _gl.m4 instead.
5061 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
5063 * src/scan-action.l: Remove. Scanning of semantic actions is
5064 handled in scan-gram.l.
5066 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
5068 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
5070 * src/location.h (struct): The file member is a uniqstr.
5071 (equal_boundaries): Use UNIQSTR_EQ for comparison.
5073 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
5075 Fix bug with non-%union parsers that have printers or destructors,
5076 which led to a Bison core dump. Reported by Peter Fales in
5077 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
5079 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
5080 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
5081 not to our own type.
5082 * src/output.c (symbol_destructors_output, symbol_printers_output):
5083 Don't assume %union.
5084 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
5085 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
5086 UNION-FLAG. All callers changed.
5087 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
5088 Use type char, not unsigned int, when declaring an array of char;
5089 this lets us remove a cast.
5090 (Printers and Destructors): Add non-%union test cases.
5092 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
5094 * doc/bison.texinfo: Minor editorial changes, mostly to the new
5095 GLR writeups. E.g., avoid frenchspacing and the future tense,
5096 change "lookahead" to "look-ahead", and change "wrt" to "with
5099 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
5101 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
5102 New sections, split off from the GLR Parsers section. Put the new
5103 Simple GLR Parser near the start of the GLR section, for clarity.
5104 Rewrite connective text.
5106 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
5108 * doc/bison.texinfo (Simple GLR Parsers): New section.
5110 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
5112 * NEWS, TODO, doc/bison.texinfo:
5113 Use "look-ahead" instead of "lookahead", to be consistent.
5114 * REFERENCES: Fix incorrect reference to DeRemer and Pennello,
5115 while we're fixing "look-ahead".
5116 * src/conflicts.c (shift_set): Renamed from shiftset.
5117 (look_ahead_set): Renamed from lookaheadset.
5118 * src/print.c: Likewise.
5119 * src/getargs.c (report_args): Add "look-ahead" as the new canonical
5120 name for "lookahead".

5162 C++ compiler. (trivial change)
5164 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
5166 Spent a few hours checking out which prerequisite versions the
5167 current sources actually require. I went all the way back to
5168 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
5169 a seemingly endless set of combinations of versions more recent
5170 than that. The bottom line is that the current sources require
5171 fairly recent versions of the build tools, and it'll be some work
5173 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
5174 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
5175 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
5176 Add comments explaining why those particular versions are
5179 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
5180 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
5181 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
5183 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
5184 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
5186 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
5188 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
5189 0.11.5. Suggested by Bruno Haible.
5190 * bootstrap: Remove gettext version checking.
5192 * doc/bison.texinfo (Decl Summary): Also mention that %union
5193 can depend on prerequisite types. Problem reported by Tim
5196 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
5198 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
5199 * README-alpha: Don't tell people not to package this.
5201 * bootstrap: Don't assume $(...) works; use `...` instead.
5202 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
5205 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
5206 put into the -d output file, and mention what to do if YYSTYPE is
5209 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
5211 Undo change made earlier today: it caused autopoint to not bring
5212 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
5215 * bootstrap: Check that gettext version matches what's in
5216 configure.ac. Warn users to ignore robots.txt ERROR 404.
5217 * bootstrap: Undo today's earlier change (logged below).
5218 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
5220 The gettext version checking is causing more trouble than it's
5221 curing; remove it. Problem reported by Paul Hilfinger.
5223 * bootstrap: Issue a warning that one can expect a message
5224 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
5225 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
5227 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
5229 Ensure that the C++ compiler used for testing actually works on a
5230 simple test program; if not, skip the C++-related tests. Problem
5231 reported by Vin Shelton in:
5232 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html

5242 being generated, as the GLR parser needs it even in that case.
5243 Problem reported by Troy A. Johnson
5244 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
5246 * configure.ac (AC_INIT): Update to 1.875e.

5254 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
5255 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
5256 lalr1.cc runs afoul of the first, and the last two are no longer
5257 supported by GCC 3.4.0.
5258 * README: Mention GNU m4 1.4 or later; mention m4 patches.
5259 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
5261 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
5263 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not

5285 Fix typo by replacing $1 with $option.
5286 Remove more 'intl'-related files.
5287 Don't DEFUN AM_INTL_SUBDIR twice.
5289 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,
5290 memrchr.c, strcasecmp.c, strchr.c, strrchr.c, strspn.c, strtol.c,

5295 inttypes.m4, inttypes_h.m4, isc-posix.m4, lcmessage.m4,
5296 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
5297 * src/.cvsignore: Add *.output.
5299 * src/parse-gram.y: Put copyright notice inside %{ %} so it
5300 gets copied to the output file.
5302 2004-04-28 Paul Eggert <eggert@twinsun.com>
5304 Get files from the gnulib and po repositories, instead of relying
5305 on them being in our CVS. Upgrade to latest versions of gnulib
5308 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
5309 * bootstrap: Bootstrap from gnulib and po repositories.
5310 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
5311 * README-cvs: Document these changes. Remove version numbers from
5312 mentions of build tools, since they change so often. Mention Flex.

5317 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
5319 (AC_ISC_POSIX): Remove; we no longer support this
5320 ancient OS, as it gets in the way of latest Autoconf & gnulib.
5321 (AC_HEADER_STDC): Remove: we now assume C89 or better.
5322 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
5323 Do not check for C89 headers, except for locale.h which is used
5324 by the Yacc library and must port to K&R hosts.
5325 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
5326 Do not check for C89 functions, except for setlocale which is
5327 used by the Yacc library.

5338 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
5339 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):

5375 Remove, as these files are now generated automatically
5376 by bootstrap or automake.

5552 token so that it covers all the discarded tokens.
5553 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
5554 it can be called with `%skeleton "lalr1.cc"', and do that.
5556 2004-02-02 Paul Eggert <eggert@twinsun.com>
5558 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
5559 $(top_srcdir)/lib and ../lib. This fixes a bug reported
5560 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
5561 There's no need to mention top_builddir since Automake does that
5563 (INCLUDES): Remove, as Automake says it's obsolescent.
5564 Contents migrated into AM_CPPFLAGS as described above.
5565 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
5567 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
5569 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.

5573 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
5575 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
5576 resulting parsers are compilable with C++.
5578 2003-12-23 Paul Eggert <eggert@twinsun.com>
5580 * config/depcomp, config/install-sh: Sync with Automake 1.8.
5581 * src/output.c (output_skeleton): Rename local var.
5582 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
5583 Bison tokens, as this runs afoul of the 2003-10-07 change that
5584 disallowed NUL bytes in character constants or string literals.
5586 * tests/local.at: Require Autoconf 2.59's Autotest.
5587 * tests/testsuite.at: Don't include local.at, since we now assume
5588 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
5590 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
5591 multiple inclusion warnings.

5615 * NEWS: Don't document %no-default-prec, as it's still
5617 * doc/bison.texinfo: Document %no-default-prec only if
5618 the defaultprec flag is set. Normally it's not.
5620 2003-10-04 Paul Eggert <eggert@twinsun.com>
5622 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
5623 non-modifiable lvalue, instead of a modifiable one.
5624 * doc/bison.texinfo (Actions): Document that $$ can
5625 be assigned to. Do not claim that $$ and $N are

5681 * config/announce-gen, Makefile.cfg: New.
5682 * Makefile.am: Adjust.
5683 * GNUmakefile, Makefile.maint: Update from CVS Autoconf, but
5684 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
5686 2003-08-25 Akim Demaille <akim@epita.fr>
5688 When reducing initial empty rules, Bison parser read an initial
5689 location that is not defined. This results in garbage, and that
5690 affects Bison's own parser. Therefore we need (i) to extend Bison
5691 to support a means to initialize this location, and (ii) to use
5692 this CVS Bison to fix CVS Bison's parser.
5694 * src/reader.h, reader.c (epilogue_augment): Remove, replace
5696 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
5697 * src/parse-gram.y: Adjust.
5698 (%initial-action): New.
5699 (%error-verbose): Since we require CVS Bison, there is no reason
5701 * src/scan-gram.l: Adjust.
5702 * src/Makefile.am (YACC): New, to make sure we use our own parser.
5703 * data/yacc.c (yyparse): Use b4_initial_action.
5705 2003-08-25 Akim Demaille <akim@epita.fr>
5707 * doc/bison.texinfo: Don't promote stdout for error messages.
5709 2003-08-25 Akim Demaille <akim@epita.fr>
5711 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.

5725 * data/lalr1.cc (Parser::reduce_print_): New.
5728 2003-08-25 Akim Demaille <akim@epita.fr>
5730 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
5731 error recovery loops. This patch is based on
5732 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
5733 Also, augment the similarity between lalr1.cc and yacc.c.
5734 Note: the locations of error recovery rules are not correct yet.
5736 * data/lalr1.cc: Comment changes to augment the similarity between
5737 lalr1.cc and yacc.c.
5738 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
5739 (yyerrlab1): Remove, but where it used to be (now the bottom part of
5740 yyerrlab), when hitting EOF, pop the whole stack here instead of
5741 merely falling thru the default error handling mechanism.
5742 (yyerrorlab): New label, with the old contents of YYERROR,
5743 plus the following change: pop the stack of rhs corresponding
5744 to the production that invoked YYERROR. That is how Yacc
5745 behaves (required by POSIX).
5746 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
5749 2003-08-25 Akim Demaille <akim@epita.fr>
5751 Tune local.at so that people can "autom4te -l autotest calc.at -o
5752 calc" for instance, to extract a sub test suite.
5754 * tests/testsuite.at: Move the initialization, Autotest version
5755 requirement, and AT_TESTED invocation into...
5756 * tests/local.at: here.
5757 * tests/testsuite.at: Include it for compatibility with Autoconf
5759 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
5762 2003-08-04 Paul Eggert <eggert@twinsun.com>
5764 Rework code slightly to avoid gcc -Wtraditional warnings.
5765 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
5766 The returned value is now stored in *YY0. All callers changed.
5767 * src/output.c (merge_output): Adjust to the above change.
5769 2003-07-26 Paul Eggert <eggert@twinsun.com>
5771 * data/glr.c (YYASSERT): New macro.
5772 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
5773 yyresolveStates, yyprocessOneStack):
5774 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
5775 Derived from a suggestion by Frank Heckenbach.
5777 2003-07-25 Paul Eggert <eggert@twinsun.com>
5779 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
5780 for portability to K&R C (after ansi2knr, presumably). See
5781 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
5782 by Frank Heckenbach, though I have omitted the structure-initialization
5783 part of his glr-knr.diff patch since I recall that the Portable
5784 C Compiler didn't require that change.
5786 Let the user specify how to allocate and free memory.
5787 Derived from a suggestion by Frank Heckenbach in

5790 All uses of free, malloc, realloc changed to use these macros,
5791 and unnecessary casts removed.
5792 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
5794 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
5796 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):

5817 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
5818 yyreportTree): Do not assume that size_t is the same width as int,
5819 when printing sizes. Print sizes using an unsigned format.
5820 Problem reported by Frank Heckenbach in
5821 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
5823 Port to Forte Developer 7 C compiler.
5824 * data/glr.c (struct YYLTYPE): If locations are not being used,
5825 declare a single dummy member, as empty structs do not conform
5827 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
5828 the Forte Developer 7 C compiler complains that end-of-loop
5829 code is not reached.
5831 2003-06-17 Paul Eggert <eggert@twinsun.com>

5873 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
5874 `How Can I Reset @code{yyparse}', since texinfo does not allow
5875 arbitrary @ in node names.
5877 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
5878 shouldn't be needed according to the gettext 0.12.1 documentation
5879 but which seem to be needed anyway: codeset.m4 glibc21.m4
5880 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4

5902 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
5903 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
5904 the tests right now.
5905 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
5906 yyerror are declared before use; C99 requires this.

5910 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
5912 (yyrecoverSyntaxError): Correct the logic for setting and testing
5914 Correct comment on handling EOF.
5915 Allow states with only a default reduction, rather than failing

5918 Fixes to avoid problem that $-N rules in GLR parsers can cause
5919 buffer overruns, corrupting state.
5921 * src/output.c (prepare_rules): Output max_left_semantic_context
5923 * src/reader.h (max_left_semantic_context): New variable declaration.

5938 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
5940 * tests/cxx-type.at: Exercise location information; update tests
5941 to differentiate output with and without locations.
5942 Remove forward declarations of yylex and yyerror---caused errors
5943 because default YYLTYPE not yet defined.
5944 Change semantic actions to compute strings, rather than printing
5945 them directly (to test proper passing of semantics values). Change
5946 output to prefix notation and update test data and expected results.
5947 (yylex): Track locations.
5948 (stmtMerge): Return value rather than printing, and include arguments
5951 2003-06-03 Paul Eggert <eggert@twinsun.com>

5961 Rename local vars to avoid warnings.
5962 * tests/glr-regression.at (Improper handling of embedded actions
5963 and $-N in GLR parsers): Remove unused local variable from yylex.
5964 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
5965 (void) as arg when not pure, since we now assume C89 when building
5966 Bison. Pacify GCC by using parameter.
5968 2003-06-02 Paul Eggert <eggert@twinsun.com>
5970 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
5971 yy::Location::lines, yy::Location::columns): Rename arguments
5972 to avoid shadowing; this removes a warning generated by GCC 3.3.
5974 2003-06-01 Paul Eggert <eggert@twinsun.com>
5976 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
5977 to g++, as GCC 3.3 complains if you do it.
5978 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
5979 everything that WARNING_CFLAGS has, except omit warnings
5980 not suitable for C++.
5981 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
5982 * tests/atlocal.in (CXXFLAGS): New var.
5983 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
5985 Fix a GLR parser bug I reported in February; see
5986 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
5987 The problem was that GLR parsers did not conform to the C standard,
5988 because actions like { $1 = $2 + $3; } expanded to expressions
5989 that invoked YYFILL in separate subexpressions, and YYFILL assigned
5990 to a local variable. The C standard says that expressions
5991 like (var = f ()) + (var = f ()) have undefined behavior.
5992 Another problem was that GCC sometimes issues warnings that
5993 yyfill and its parameters are unused.
5995 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
5997 (yyfill): New function.
5999 (yyuserAction): Change type of yynormal to bool, so that it matches
6000 the new yyfill signature. Mark it as possibly unused.
6003 Follow up on a bug I reported in February, where a Bison-generated
6004 parser can loop. Provide a test case and a fix for yacc.c. I
6005 don't have a fix for lalr1.cc or for glr.c, unfortunately.
6006 The original bug report is in:
6007 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
6009 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
6010 macro's size was becoming unwieldy.
6011 (yyerrlab): Do not discard an empty lookahead symbol, as this
6012 might destroy garbage.
6013 (yyerrorlab): New label, with the old contents of YYERROR,
6014 plus the following change: pop the stack of rhs corresponding
6015 to the production that invoked YYERROR. That is how Yacc
6016 behaves, and POSIX requires this behavior.
6017 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
6018 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
6019 Define 'alarm' to do nothing if unistd.h is not available.
6020 Add a new rule "exp: '-' error;" to test the above change to
6021 data/yacc.c. Use 'alarm' to abort any test taking longer than
6022 10 seconds, as it's probably looping.
6023 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
6024 Also, the new yacc.c generates two fewer diagnostics for an
6027 2003-05-24 Paul Eggert <eggert@twinsun.com>
6029 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
6030 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
6031 This fixes a problem reported by John Bowman when the Compaq/HP
6032 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
6034 * data/yacc.c (union yyalloc): Likewise.
6035 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
6037 Switch from 'int' to 'bool' where that makes sense.

6042 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
6043 Return or accept bool, not int. All callers changed.
6044 * lib/bbitset.h: (bitset_toggle_, bitset_copy_, bitset_and_or_cmp_,
6045 bitset_andn_or_cmp_, bitset_or_and_cmp_): Likewise.

6063 lbitset_xor_cmp): Likewise.
6064 * lib/bbitset.h: Include <stdbool.h>.
6065 (struct bitset_vtable): The following members now return bool, not
6066 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,

6096 * src/state.c (state_rule_lookaheads_print): Likewise.
6098 * config/install-sh: Sync from automake 1.7.5.
6100 2003-05-14 Paul Eggert <eggert@twinsun.com>
6102 * src/parse-gram.y (rules_or_grammar_declaration): Require a
6103 semicolon after a grammar declaration, in the interest of possible
6104 future changes to the Bison input language.
6105 Do not allow a stray semicolon at the start of the grammar.
6106 (rhses.1): Allow one or more semicolons after any rule, including
6107 just before "|" as required by POSIX.
6108 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
6111 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
6113 %parse-param support for lalr1.cc.
6115 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
6116 b4_cc_constructor_calls, b4_cc_constructor_call,
6117 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
6119 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
6120 parse-param arguments.
6121 (yy::b4_parser_class_name): Declare instance variables to
6122 hold parse-param arguments.
6123 * tests/calc.at: s/value/semantic_value/ because value clashes
6124 with a member of yy::b4_parser_class_name. Adjust C++ code
6125 to handle %parse-param. Enable %parse-param test in C++.
6127 2003-05-12 Paul Eggert <eggert@twinsun.com>
6129 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
6130 English a bit. Fix fclose typo. Change "const char" to "char
6131 const", and use ANSI C rather than K&R for "main". Suggest
6132 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
6133 and suggest yy_switch_to_buffer.
6135 2003-05-05 Paul Eggert <eggert@twinsun.com>
6137 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
6138 C89. This avoids a diagnostic on compilers that define __STDC__
6139 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
6140 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
6142 2003-05-03 Paul Eggert <eggert@twinsun.com>
6144 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
6145 Do not overrun array bounds.
6146 This should fix a bug reported today by Olatunji Oluwabukunmi in
6147 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
6149 2003-04-29 Akim Demaille <akim@epita.fr>
6151 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
6152 * src/getargs.c, src/getargs.h: here, as bool, not int.
6153 (nondeterministic_parser): New.
6154 * src/parse-gram.y, src/scan-gram.l: Support
6155 %nondeterministic-parser.
6156 * src/output.c (prepare): Use nondeterministic_parser instead
6157 of glr_parser where appropriate.
6158 * src/tables.c (conflict_row, action_row, save_row)
6159 (token_actions, token_actions, pack_vector): Ditto.
6161 2003-04-29 Akim Demaille <akim@epita.fr>
6163 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
6165 2003-04-29 Akim Demaille <akim@epita.fr>
6167 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
6168 with %pure-parser and %locations to exercise the patch from Yakov
6171 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
6173 * data/yacc.c: (b4_lex_param): Corrected for the case where
6174 %lex-param is provided and %pure-parser isn't.
6176 2003-04-27 Paul Eggert <eggert@twinsun.com>
6178 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
6179 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
6180 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
6181 if it is not defined.
6182 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
6184 2003-04-26 Paul Eggert <eggert@twinsun.com>
6186 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
6187 Declare to be of type suitable for the ninf value itself, not of
6188 type suitable for the corresponding table, since the latter might
6189 be unsigned but the ninf value might be negative. This fixes a
6190 bug reported by Alexandre Duret-Lutz in
6191 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
6193 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
6194 invokes it. We shouldn't invoke it twice because it will attempt
6195 to put error.o in the archive twice. This fixes a glitch reported
6196 by Martin Mokrejs in
6197 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
6199 2003-04-21 Paul Eggert <eggert@twinsun.com>
6201 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
6204 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
6206 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
6207 Fix obvious typo that results in uncompilable GLR parsers
6208 when both %pure-parser and %locations are used. (trivial change)
6210 2003-04-17 Paul Eggert <eggert@twinsun.com>
6212 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
6213 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
6214 Do not insert the expected token via unput, as this runs afoul
6215 of a POSIX-compatibility bug in flex 2.5.31.
6216 All uses changed to BEGIN the parent state,
6217 since we no longer insert the expected token via unput.
6218 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
6219 that is no longer emitted after the above change.
6221 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
6222 the first one. This change is from Paul Hilfinger, and it fixes
6223 regression reported by Werner Lemberg in
6224 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
6226 (resolve_sr_conflict): Don't invoke state_errs_set
6227 unless one or more tokens have been explicitly made errors.
6228 Otherwise, the above change causes Bison to abort.
6230 * tests/existing.at (GNU pic Grammar): New test case, taken from
6233 2003-03-31 Akim Demaille <akim@epita.fr>
6235 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
6237 2003-03-31 Akim Demaille <akim@epita.fr>
6239 * src/output.c (prepare_symbols): Avoid trailing spaces in the
6242 2003-03-31 Akim Demaille <akim@epita.fr>
6244 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
6245 From Paul Hilfinger.
6247 2003-03-29 Akim Demaille <akim@epita.fr>
6249 * m4/error.m4: Do not put under dynamic conditions some code which
6250 expansion is under static control.
6252 2003-03-29 Akim Demaille <akim@epita.fr>
6254 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
6256 2003-03-29 Akim Demaille <akim@epita.fr>
6258 * doc/bison.texinfo (Strings are Destroyed): New.
6260 2003-03-13 Paul Eggert <eggert@twinsun.com>
6262 * .cvsignore: Add configure.lineno.
6263 * src/.cvsignore: Add yacc.
6264 * tests/.cvsignore: Add testsuite.log.
6265 * doc/fdl.texi: Sync with latest FSF version.
6267 2003-03-12 Paul Eggert <eggert@twinsun.com>
6269 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
6270 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
6271 cursor, instead of leaving it undefined. This fixes a bug
6272 reported by Tim Van Holder in
6273 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
6274 * tests/input.at (Torturing the Scanner): Test the scanner on
6275 an empty input file, which was Tim Van Holder's test case.
6277 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
6278 <sys/resource.h> can be included, include sys/time.h and
6279 sys/times.h first, if available. This works around the SunOS
6280 4.1.4 porting bug reported by Bruce Becker in
6281 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
6283 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
6284 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
6287 Merge changes from gnulib. This was prompted because the CVS
6288 snapshot didn't build on Solaris 7 due to strnlen problems.
6290 These changes need to be merged back into gnulib:
6291 * lib/hash.c: Include <stdbool.h> unconditionally.
6292 * m4/onceonly.m4 (m4_quote): New macro.
6293 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
6294 Quote AC_FOREACH variable-expansions properly.
6295 The 2003-01-03 obstack.h change also needs merging.
6296 {end of changes requiring merging}
6298 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
6299 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
6300 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
6301 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
6302 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
6303 New files, imported from gnulib.
6304 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
6307 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
6308 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
6311 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
6313 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
6314 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
6315 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
6316 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
6317 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
6318 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
6319 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
6320 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
6321 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
6322 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
6323 (jm_PREREQ_ARGMATCH): Remove.
6324 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
6325 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
6327 * src/system.h: Include <stdbool.h> unconditionally.
6329 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
6330 assuming at least C89 in the bitset code for some time now.
6332 2003-03-03 Akim Demaille <akim@epita.fr>
6336 2003-03-02 Akim Demaille <akim@epita.fr>
6338 * doc/bison.texinfo (Table of Symbols): Reactivate the
6339 documentation for %lex-param, and %parse-param.
6341 2003-03-02 Akim Demaille <akim@epita.fr>
6343 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
6344 generate verbose error messages.
6345 Use the number of tokens as an upper bound in yytname, as it
6346 cannot be a non terminal.
6348 2003-03-02 Akim Demaille <akim@epita.fr>
6350 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
6353 2003-03-02 Akim Demaille <akim@epita.fr>
6355 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
6356 Use them to exercise yycheck overrun.
6357 Based on Andrew Suffield's grammar.
6359 2003-03-02 Akim Demaille <akim@epita.fr>
6361 Create tests/local.at for Bison generic testing macros.
6363 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
6364 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
6366 * tests/calc.at (AT_CHECK_CALC): Adjust.
6367 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
6368 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
6369 * tests/local.at: here.
6370 (AT_COMPILE_CXX): Tags the tests using it as c++.
6371 Ignore the test if CXX is not functional.
6373 2003-03-01 Paul Eggert <eggert@twinsun.com>
6375 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
6376 not loc->end, since loc->end might contain garbage and this leads
6377 to undefined behavior on some platforms.
6378 (id_loc, token_start): Use (IF_LINTed) initial values that do not
6379 depend on *loc, so that the reader doesn't give the the false
6380 impression that *loc is initialized.
6381 (<INITIAL>"%%"): Do not bother setting code_start, since its value
6382 does not survive the return.
6384 2003-03-01 Akim Demaille <akim@epita.fr>
6386 * src/scan-gram.l (code_start): Always initialize it when entering
6387 into yylex, as SC_EPILOGUE is activated *before* the corresponding
6388 yylex invocation. An alternative would be making it static, but
6389 then it starts with the second %%'s beginning, instead of its end.
6391 2003-02-28 Paul Eggert <eggert@twinsun.com>
6393 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
6394 around a UnixWare 7.1.1 porting bug reported by John Hughes in
6395 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
6397 2003-02-26 Paul Eggert <eggert@twinsun.com>
6399 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
6400 Remove Sequent/Pyramid discussion (nobody uses them any more).
6401 Merge VMS and MS-DOS discussion; these ports may well be dead
6402 but let's keep mentioning them for now. Put <> around email
6403 addresses. Add copyright notice.
6405 2003-02-24 Paul Eggert <eggert@twinsun.com>
6407 * data/glr.c (yy_reduce_print): yylineno -> yylno,
6408 to avoid collision with flex use of yylineno.
6409 Problem reported by Bruce Lilly in
6410 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
6411 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
6412 * data/yacc.c (yy_reduce_print): Likewise.
6414 * config/depcomp: Sync with Automake 1.7.3.
6416 2003-02-21 Akim Demaille <akim@epita.fr>
6418 * data/lalr1.cc: Use temporary variables instead of casts to
6419 change integer types.
6420 Suggested by Paul Eggert.
6422 2003-02-21 Akim Demaille <akim@epita.fr>
6424 * doc/bison.texinfo: Use "location" consistently to refer to @n,
6425 to avoid confusions with lalr1.cc's notion of Position.
6426 Suggested by Paul Eggert.
6428 2003-02-20 Akim Demaille <akim@epita.fr>
6430 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
6431 before initial_columns.
6432 (location.hh): Use consistent variable names when defining the
6434 Use "last" so that we subtract from Positions, not from unsigned.
6436 2003-02-20 Akim Demaille <akim@epita.fr>
6438 * data/lalr1.cc (position.hh): New subfile, including the extended
6439 and Doxygen'ed documentation of class Position.
6440 (location.hh): Use it.
6441 Document a` la Doxygen.
6442 With the help of Benoit Perrot.
6444 2003-02-20 Akim Demaille <akim@epita.fr>
6446 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
6448 Redefine AT_YYERROR_SEES_LOC_IF using it.
6449 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
6451 Don't use the location in yy::Parser::error_ and
6452 yy::Parser::print_ when not %locations.
6453 Activate more lalr1.cc tests.
6455 2003-02-19 Akim Demaille <akim@epita.fr>
6457 * data/lalr1.cc: When displaying a line number, be sure to make it
6460 2003-02-19 Akim Demaille <akim@epita.fr>
6462 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
6464 (YYABORT, YYACCEPT, YYERROR): New.
6465 * tests/calc.at: Renable the lalr1.cc test.
6467 2003-02-19 Akim Demaille <akim@epita.fr>
6469 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
6470 error recovery, mixing with/without pops and discarding of the
6473 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
6475 2003-02-17 Paul Eggert <eggert@twinsun.com>
6477 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
6478 * tests/testsuite.at (AT_COMPILE): Use them.
6479 This fixes the testsuite problem reported by Robert Lentz in
6480 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
6482 2003-02-12 Paul Eggert <eggert@twinsun.com>
6484 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
6485 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
6486 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
6487 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
6488 Check for malloc failure, for consistency with yacc.c.
6489 (yytname_size): Remove, for consistency with yacc.c.
6491 The bug still remains in data/lalr1.cc, as I didn't have time
6494 2003-02-06 Akim Demaille <akim@epita.fr>
6496 * configure.ac (GXX): Rename as...
6497 (CXX): this, to keep the original Autoconf semantics.
6499 * data/lalr1.cc: Fix b4_copyright invocations.
6500 If YYDEBUG is not defined, don't depend upon name_ being defined.
6501 (location.hh): Include string and iostream.
6502 (Position::filename): New member.
6503 (Position::Position ()): New.
6504 (operator<< (Position)): New.
6505 (operator- (Position, int)): New.
6506 (Location::first, Location::last): Rename as...
6507 (Location::begin, Location::end): these, to mock the conventional
6509 (operator<< (Location)): New.
6510 * tests/atlocal.in (CXX): New.
6511 * tests/testsuite.at (AT_COMPILE_CXX): New.
6512 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
6513 locations in a more synthetic way.
6514 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
6516 Adjust the C locations to match those from Emacs: first column is
6518 Change all the expected results.
6519 Conform to the GCS: simplify the locations when applicable.
6520 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
6521 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
6522 these CPP macros with the m4 macros new defined by...
6523 (AT_CHECK_PUSHDEFS): this, i.e.:
6524 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
6525 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
6527 (AT_CHECK_POPDEFS): Undefine them.
6528 (AT_CHECK_CALC_LALR1_CC): New.
6529 Use it for the first lalr1.cc test.
6531 2003-02-04 Akim Demaille <akim@epita.fr>
6533 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
6534 Location as is defined.
6536 2003-02-04 Akim Demaille <akim@epita.fr>
6538 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
6539 name_ being defined.
6541 2003-02-03 Paul Eggert <eggert@twinsun.com>
6543 * src/gram.h (start_symbol): Remove unused decl.
6545 Use more-consistent naming conventions for local vars.
6547 * src/derives.c (derives_compute): Change type of local var from
6549 * src/gram.c (grammar_rules_partial_print): Likewise.
6550 * src/print.c (print_core): Likewise.
6551 * src/reduce.c (reduce_grammar_tables): Likewise.
6553 * src/gram.c (grammar_dump): Change name of item_number *
6554 local var from r to rp.
6555 * src/nullable.c (nullable_compute): Likewise.
6557 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
6559 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
6560 for symbol or symbol_number var.
6561 * src/reader.c (grammar_start_symbol_set): Likewise.
6562 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
6564 * src/state.c (transitions_to): Likewise.
6565 * src/state.h: Likewise.
6566 * src/tables.c (symbol_number_to_vector_number): Likewise.
6568 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
6571 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
6574 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
6577 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
6578 Use str, not s, for char * var. Use ch, not c, for character var.
6579 Use size for size var.
6581 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
6583 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
6585 * src/uniqstr.h: Likewise.
6587 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
6588 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
6589 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
6590 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
6591 param to have same name as that of enum, so that we don't use
6592 "s" to stand for a non-state.
6594 2003-02-02 Akim Demaille <akim@epita.fr>
6596 * src/scan-skel.l: Scan more than one inert character per yylex
6599 2003-02-01 Paul Eggert <eggert@twinsun.com>
6603 * po/LINGUAS: Add ms.
6605 2003-01-30 Akim Demaille <akim@epita.fr>
6607 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
6609 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
6611 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
6614 Changes in response to error report by S. Eken: GLR mode does not
6615 handle negative $ indices or $ indices in embedded rules correctly.
6616 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
6618 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
6619 (b4_rhs_location): Ditto.
6620 (yyfill): New function to copy from stack tree into array
6622 (yyuserAction): Modify to allow incremental move of semantic values
6623 to rhs array when in GLR mode.
6624 Define YYFILL to use in user-defined actions to fill semantic array
6626 Remove dummy use of yystack, as there is now a guaranteed use.
6627 (yydoAction): Modify to allow incremental move of semantic values
6628 to rhs array when in GLR mode.
6629 (yyresolveAction): Ditto.
6630 (yyglrShiftDefer): Update comment.
6631 (yyresolveStates): Use X == NULL for pointers, not !X.
6632 (yyglrReduce): Ditto.
6635 * tests/glr-regr1.at: Rename to ...
6636 * tests/glr-regression.at: Add new regression test for the problems
6637 described above (adapted from S. Eken).
6638 Update copyright notice.
6639 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
6640 * tests/Makefile.am: Ditto.
6642 2003-01-28 Paul Eggert <eggert@twinsun.com>
6644 * data/lalr1.cc: Do not use @output_header_name@ unless
6645 b4_defines_flag is set. This fixes two bugs reported by
6647 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
6648 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
6650 2003-01-21 Paul Eggert <eggert@twinsun.com>
6652 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
6653 we don't need to worry about yyerrlab1 being reported as an
6654 "unused label" by non-GCC C compilers. The downside is that if
6655 locations are used then a couple of statements are duplicated each
6656 time YYERROR is invoked, but the upside is that the warnings
6658 (yyerrlab1): Move code to YERROR.
6659 (yyerrlab2): Remove. Change uses back to yyerrlab1.
6660 This reverts some of the 2002-12-27 change.
6662 2003-01-17 Paul Eggert <eggert@twinsun.com>
6664 * src/output.c (symbol_printers_output): Fix typo that led
6665 to core dump. Problem reported by Antonio Rus in
6666 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
6668 2003-01-13 Akim Demaille <akim@epita.fr>,
6669 Quoc Peyrot <chojin@lrde.epita.fr>,
6670 Robert Anisko <anisko_r@lrde.epita.fr>
6672 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
6673 when the stacks contain one element, as the loop would otherwise
6674 free the last state, and then use the top state (the one we just
6675 popped). This means that the initial elements will not be freed
6676 explicitly, as is the case in yacc.c; it is not a problem, as
6677 these elements have fake values.
6679 2003-01-11 Paul Eggert <eggert@twinsun.com>
6681 * NEWS: %expect-violations are now just warnings, reverting
6682 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
6683 bootstrapping problem reported by Matthias Klose; see
6684 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
6685 * src/conflicts.c (conflicts_print): Likewise.
6686 * tests/conflicts.at (%expect not enough, %expect too much,
6687 %expect with reduce conflicts): Likewise.
6688 * doc/bison.texinfo (Expect Decl): Document this. Also mention
6689 that the warning is enabled if the number of conflicts changes
6690 (not necessarily increases).
6692 * src/getargs.c (version): Update copyright year.
6694 2003-01-09 Akim Demaille <akim@epita.fr>
6696 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
6698 2003-01-08 Paul Eggert <eggert@twinsun.com>
6700 * Makefile.maint (WGETFLAGS):
6701 New macro, containing "-C off" to disable proxy caches.
6702 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
6703 (rel-check): Use $(WGET) instead of wget.
6705 2003-01-06 Paul Eggert <eggert@twinsun.com>
6707 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
6708 the GLR paper of Scott, Johnstone and Hussain.
6710 2003-01-04 Paul Eggert <eggert@twinsun.com>
6712 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
6713 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
6714 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
6715 (EXTRA_LIBRARIES): New var, for liby.a.
6716 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
6717 (EXTRA_SCRIPTS): New var, for yacc.
6719 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
6720 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
6721 Problem reported by Nelson H. F. Beebe.
6723 2003-01-03 Paul Eggert <eggert@twinsun.com>
6725 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
6726 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
6727 when compiling Bison 1.875's `bitset bset = obstack_alloc
6728 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
6730 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
6731 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
6732 grow to a huge size with typical invocation.
6734 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
6735 Use the pattern recommended by Autoconf 2.57, except also protect
6736 against double-definition.
6737 * src/system.h: Likewise.
6738 Portability issues reported by Nelson H. F. Beebe.
6740 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
6741 All uses changed. Provide a definition in both C and C++.
6742 (yytrue, yyfalse): Define even if defined (__cplusplus).
6744 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
6745 Reported by Nelson H. F. Beebe.
6747 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
6749 2003-01-02 Paul Eggert <eggert@twinsun.com>
6751 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
6752 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
6753 Bug reported by Nelson H. F. Beebe.
6755 2003-01-01 Paul Eggert <eggert@twinsun.com>
6759 2002-12-30 Paul Eggert <eggert@twinsun.com>
6761 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
6763 (<INITIAL>","): Here. This causes stray "," to be treated
6766 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
6767 last brace in braced code when not in Yacc mode, for compatibility
6768 with Bison 1.35. This resurrects the 2001-12-15 patch to
6771 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
6772 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
6774 2002-12-28 Paul Eggert <eggert@twinsun.com>
6776 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
6777 that of SYM's type. This fixes Debian bug 168069, reported by
6780 2002-12-28 Paul Eggert <eggert@twinsun.com>
6784 Switch back to the Yacc style of conflict reports, undoing some
6785 of the 2002-07-30 change.
6786 * doc/bison.texinfo (Understanding): Use Yacc style for
6787 conflict reports. Also, use new way of locating rules.
6788 * src/conflicts.c (conflict_report):
6789 Renamed from conflict_report_yacc, removing the old
6790 'conflict_report'. Translate the entire conflict report at once,
6791 so that we don't assume that "," has the same interpretation in
6793 (conflicts_output): Use Yacc-style conflict report for each state,
6794 instead of our more-complicated style.
6795 (conflicts_print): Use Yacc-style conflict report, except print
6796 the input file name when not emulating Yacc.
6797 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
6798 Conflicted Reduction, %expect not enough, %expect too much,
6799 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
6800 * tests/existing.at (GNU Cim Grammar): Likewise.
6801 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
6803 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
6804 fatal): Don't invoke fflush; it's not needed and it might even be
6805 harmful for stdout, as stdout might not be open.
6806 * src/reduce.c (reduce_print): Likewise.
6808 2002-12-27 Paul Eggert <eggert@twinsun.com>
6810 Fix a bug where error locations were not being recorded correctly.
6811 This problem was originally reported by Paul Hilfinger in
6812 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
6814 * data/yacc.c (yyparse): New local var yylerrsp, to record the
6815 top of the location stack's error locations.
6816 (yyerrlab): Set it. When discarding a token, push its location
6817 onto yylerrsp so that we don't lose track of the error's end.
6818 (yyerrlab1): Now is only the target of YYERROR, so that we can
6819 properly record the location of the action that failed. For GCC
6820 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
6821 GCC warning about yyerrlab1 being unused if YYERROR is unused.
6822 (yyerrlab2): New label, which yyerrlab now falls through to.
6823 Compute the error's location by applying YYLLOC_DEFAULT to
6824 the locations of all the symbols that went into the error.
6825 * doc/bison.texinfo (Location Default Action): Mention that
6826 YYLLOC_DEFAULT is also invoked for syntax errors.
6827 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
6828 Error locations include the locations of all the tokens that were
6829 discarded, not just the last token.
6831 2002-12-26 Paul Eggert <eggert@twinsun.com>
6833 * src/files.c: Include quote.h.
6834 (compute_output_file_names): Warn if we detect conflicting
6835 outputs to the same file. This should catch the misunderstanding
6836 exemplified by Debian Bug 165349, reported by Bruce Stephens..
6838 * src/conflicts.c (conflicts_print): If the user specifies
6839 "%expect N", report an error if there are any reduce/reduce
6840 conflicts. This is what the manual says should happen.
6841 This fixes Debian bug 130890, reported by Anthony DeRobertis.
6842 * tests/conflicts.at (%expect with reduce conflicts): New test.
6844 Don't use m4_include on relative file names, as it doesn't work as
6845 desired if there happens to be a file with that name under ".".
6847 * m4sugar/version.m4: Remove; it was included but it wasn't used.
6848 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
6849 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
6850 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
6851 * src/output.c (output_skeleton): Use full path names when
6852 specifying a file to include; don't rely on include path, as
6853 it's unreliable when the working file contains a file with
6856 2002-12-25 Paul Eggert <eggert@twinsun.com>
6858 Remove obsolete references to bison.simple and bison.hairy.
6859 Problem mentioned by Aubin Mahe in
6860 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
6861 * data/glr.c: Comment fix.
6862 * doc/bison.1: Remove references. Also, mention "yacc".
6864 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
6867 * src/parse-gram.y (declaration): Use enum "report_states" rather
6868 than its numeric value 1.
6870 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
6871 opening a new one. This fixes Debian bug 165349, reported by
6874 2002-12-24 Paul Eggert <eggert@twinsun.com>
6878 * Makefile.maint (cvs-update): Don't assume that the shell
6879 supports $(...), as Solaris sh doesn't.
6881 * src/parse-gram.y (lloc_default): Remove test for empty
6882 nonterminals at the end, since it didn't change the result.
6884 2002-12-24 Paul Eggert <eggert@twinsun.com>
6886 If the user does not define YYSTYPE as a macro, Bison now declares it
6887 using typedef instead of defining it as a macro. POSIX requires this.
6888 For consistency, YYLTYPE is also declared instead of defined.
6890 %union directives can now have a tag before the `{', e.g., the
6891 directive `%union foo {...}' now generates the C code
6892 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
6893 The default union tag is `YYSTYPE', for compatibility with Solaris 9
6894 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
6895 instead of `yyltype'.
6897 `yystype' and `yyltype' are now obsolescent macros instead of being
6898 typedefs or tags; they are no longer documented and will be
6899 withdrawn in a future release.
6901 * data/glr.c (b4_location_type): Remove.
6902 (YYSTYPE): Renamed from yystype.
6903 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
6904 (struct YYLTYPE): Renamed from struct yyltype.
6905 (YYLTYPE): Renamed from yyltype.
6906 (yyltype, yystype): New (and obsolescent) macros,
6907 for backward compatibility.
6908 * data/yacc.c: Likewise.
6910 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
6911 does not specify a union tag. This is for compatibility with
6914 * src/parse-gram.y (add_param): 2nd arg is now char * not char
6915 const *, since it is now modified by stripping surrounding { }.
6916 (current_braced_code): Remove.
6917 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
6918 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
6919 trailing " {...}". Now of type <chars>.
6920 (grammar_declaration): Adjust to bundled tokens.
6921 (code_content): Remove; stripping is now done by add_param.
6922 (print_token_value): Print contents of bundled tokens.
6923 (token_name): New function.
6925 * src/reader.h (braced_code, current_braced_code): Remove.
6926 (token_name): New decl.
6928 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
6929 token_type, not braced_code code_kind. All uses changed.
6930 (SC_PRE_CODE): New state, for scanning after a keyword that
6931 has (or usually has) an immediately-following braced code.
6932 (token_type): New local var, to keep track of which token type
6933 to return when scanning braced code.
6934 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
6935 <INITIAL>"%parse-param", <INITIAL>"%printer",
6936 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
6937 instead of returning a token type immediately.
6938 (<INITIAL>"{"): Set token type.
6939 (<SC_BRACED_CODE>"}"): Use it.
6940 (handle_action_dollar, handle_action_at): Now returns bool
6941 indicating success. Fail if ! current_rule; this prevents a core dump.
6942 (handle_symbol_code_dollar, handle_symbol_code_at):
6943 Remove; merge body into caller.
6944 (handle_dollar, handle_at): Complain in invalid contexts.
6946 * NEWS, doc/bison.texinfo: Document the above.
6947 * NEWS: Fix years and program names in copyright notice.
6949 2002-12-17 Paul Eggert <eggert@twinsun.com>
6951 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
6952 Reporting, Table of Symbols): Omit mentions of %lex-param and
6953 %parse-param from the documentation for now.
6955 2002-12-15 Paul Eggert <eggert@twinsun.com>
6957 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
6958 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
6959 lookahead symbol, and which sets yychar in parser actions) and it
6960 disagreed with the Bison documentation. Bug
6961 reported by Andrew Walrond.
6963 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
6964 as the caller now does that.
6965 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
6966 (YYEMPTY): Parenthesize right hand side, since others use it.
6967 (yyparse): Don't assume that our generated code is the only code
6970 2002-12-13 Paul Eggert <eggert@twinsun.com>
6974 POSIX requires a "yacc" command.
6975 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
6976 (MOSTLYCLEANFILES): Add yacc.
6978 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
6979 as an alias for bison y.
6981 * po/LINGUAS: Add da.
6983 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
6984 problem with latest <getopt.h>.
6985 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
6987 * doc/fdl.texi: Upgrade to 1.2.
6988 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
6989 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
6990 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
6992 * config/install-sh: Sync with autotools.
6994 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
6995 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
6996 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
6997 locations are requested.
6998 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
6999 locations are requested.
7001 2002-12-12 Paul Eggert <eggert@twinsun.com>
7003 Remove unportable casts and storage allocation tricks.
7004 While we're at it, remove almost all casts, since they
7005 usually aren't needed and are a sign of trouble.
7007 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
7009 * src/derives.c (derives_compute): Do not subtract NTOKENS from
7010 the pointer DSET returned by malloc; this isn't portable.

7031 symbol_number_to_vector_number): Likewise.
7033 * src/gram.h (int_of_rule_number): Remove; no longer used.
7035 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
7036 since the resulting storage is always stored into.

7041 * src/muscle_tab.c (muscle_m4_output):
7042 Now inline. Return bool, not int.
7043 * src/state.c (state_compare): Likewise.

7054 symbol_translation_processor, hash_symbol_comparator,
7055 hash_symbol_hasher): Likewise.
7056 * src/uniqstr.c (uniqstr_print_processor): Likewise.
7057 * src/muscle_tab.c (muscles_m4_output):
7058 Use new functions instead of casting old functions unportably.
7059 * src/state.c (state_hash_new): Likewise.
7060 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
7061 symbols_token_translations_init):
7063 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
7065 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
7066 var instead of casting to long, to avoid casts.
7067 (prepare_states): Use MALLOC rather than alloca, so that we don't
7068 have to worry about alloca.
7069 * src/state.c (state_hash_lookup): Likewise.
7071 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
7072 local var instead of casting to unsigned char, to avoid casts.

7075 STATE_ALLOC): Remove.
7076 (transitions_new, errs_new, reductions_new, state_new): Use malloc
7077 rather than calloc, and use offsetof to avoid allocating slightly
7079 (state_new): Initialize all members.
7081 * src/state.c (state_hash): Use unsigned accumulator, not signed.
7083 * src/symtab.c (symbol_free): Remove; unused.
7084 (symbol_get): Remove cast in lhs of assignment.
7085 (symbols_do): Now static. Accept generic arguments, not
7086 hashing-related ones.
7088 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
7089 (symbol_processor): Remove.
7090 (symbols_do): Remove decl; now static.
7092 * src/system.h (alloca): Remove; decl no longer needed.
7093 (<stddef.h>): Include, for offsetof.
7094 (<inttypes.>, <stdint.h>): Include if available.
7095 (uintptr_t): New type, if system lacks it.
7096 (CALLOC, MALLOC, REALLOC): New macros.
7097 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
7100 * src/tables.c (table_size): Now int, to pacify GCC.
7101 (table_grow, table_ninf_remap): Use signed table size.
7102 (save_row): Don't bother initializing locals when not needed.
7103 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
7104 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
7106 * src/vcg.h: Correct misspellings.
7108 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
7111 * src/getargs.c (getargs): Don't assume EOF == -1.
7113 2002-12-09 Paul Eggert <eggert@twinsun.com>
7115 Change identifier spellings to avoid collisions with names
7116 that are reserved by POSIX.
7118 Don't use names ending in _t, since POSIX reserves them.
7119 For consistency, remove _e and _s endings -- they're weren't
7120 needed to remove ambiguity. All uses changed.
7121 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
7122 turn was just renamed from struniq_t.
7123 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
7124 which in turn was just renamed from struniq_processor_t.
7125 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which

7195 * tests/input.at (Torturing the Scanner): Rename value_t -> value,
7196 value_t_as_yystype -> value_as_yystype.
7198 Don't include <errno.h> in the mainstream code, since it
7199 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
7200 * lib/get-errno.c, lib/get-errno.h: New files.
7201 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
7203 * src/files.c (xfopen, xfclose): Use get_errno instead of errno.

7209 (handle_action_dollar, handle_action_at): Likewise.
7210 * src/system.h: Do not include <errno.h>.
7211 (TAB_EXT): Renamed from EXT_TAB.
7212 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
7214 Avoid str[a-z]*, since <string.h> reserves that name space.
7215 Change all instances of "struniq" in names to "uniqstr", and
7216 likewise for "STRUNIQ" and "UNIQSTR".
7217 * src/uniqstr.c: Renamed from src/struniq.c.
7218 * src/uniqstr.h: Renamed from src/struniq.h.
7219 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.

7254 for consistency with other names.
7255 * lib/timevar.h (timevar_report): New decl.
7256 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
7259 Sort include-file uses.
7261 Reorder all include files under src to be in the order "system.h".
7262 then the ../lib include files in angle brackets (alphabetized),
7263 then the . include files in double-quotes (alphabetized). Fix
7264 dependency breakages encountered in this process, as follows:
7265 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
7266 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
7267 * src/state.h: Include "symtab.h".
7269 2002-12-08 Paul Eggert <eggert@twinsun.com>
7271 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
7272 since this causes problems when __file__ contains character
7273 sequences like "@" that are treated specially by src/scan-skel.l.
7274 Instead, just use the file's basename. This fixes the bug
7275 reported by Martin Mokrejs in
7276 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
7278 2002-12-06 Paul Eggert <eggert@twinsun.com>
7280 Add support for rules that do not have trailing semicolons, as
7281 POSIX requires. Improve the quality of locations in Bison
7284 * src/location.c: Include <quotearg.h>.
7285 (empty_location): Now const.
7286 (location_print): New function. Follow the recommendation of the
7287 GNU Coding Standards for locations that span file boundaries.
7288 * src/location.h: Do not include <quotearg.h>; no longer needed.
7289 (boundary): New type.
7290 (location_t): Use it. This allows locations to span file boundaries.
7291 All member uses changed: file -> start.file or end.file (as needed),
7292 first_line -> start.line, first_column -> start.column,
7293 last_line -> end.line, last_column -> end.column.
7294 (equal_boundaries): New function.
7295 (LOCATION_RESET, LOCATION_STEP): Remove.
7296 (LOCATION_PRINT): Remove. All callers changed to use location_print.
7297 (empty_location): Now const.
7298 (location_print): New decl.
7299 * src/parse-gram.y (lloc_default): New function, which handles
7300 empty locations more accurately.
7301 (YYLLOC_DEFAULT): Use it.
7302 (%token COLON): Remove.
7303 (%token ID_COLON): New token.
7305 (declarations, rules): Remove trailing semicolon.

7311 * src/reader.h: Include location.h.
7312 (scanner_cursor): New decl.
7313 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
7315 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
7317 (STEP): Remove. No longer needed, now that adjust_location does
7318 the work. All uses removed.
7319 (scanner_cursor): New var.
7320 (adjust_location): Renamed from extend_location. It now sets
7321 *loc and adjusts the scanner cursor. All uses changed.
7322 Don't bother testing for CR.
7323 (handle_syncline): Remove location arg; now updates scanner cursor.
7324 All callers changed.
7325 (unexpected_end_of_file): Now accepts start boundary of token or
7326 comment, not location. All callers changed. Update scanner cursor,
7328 (SC_AFTER_IDENTIFIER): New state.
7329 (context_state): Renamed from c_context. All uses changed.
7330 (id_loc, code_start, token_start): New local vars.
7331 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
7332 processing of Yacc white space and equivalents here.
7333 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
7334 instead of returning ID immediately, since we need to search for
7336 (<INITIAL>"'", "\""): Save token_start.
7337 (<INITIAL>"%{", "{", "%%"): Save code_start.
7338 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
7339 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
7340 BEGIN context_state at end, not INITIAL.
7341 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
7342 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
7343 Return correct token start.
7344 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
7345 the start of a character, string or multiline comment is found.
7346 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
7347 Reduction): Adjust reported locations to match the more-precise
7348 results now expected.
7349 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
7350 * tests/reduce.at (Useless Rules, Reduced Automaton,
7351 Underivable Rules): Likewise.
7352 * tests/regression.at (Invalid inputs): No longer `expecting ";"
7353 or "|"' now that so many other tokens are allowed by the new grammar.
7355 * src/complain.h (current_file): Remove duplicate decl;
7356 current_file is now owned by files.h.
7357 * src/complain.c, src/scan-gram.l: Include files.h.
7359 2002-12-06 Paul Eggert <eggert@twinsun.com>
7361 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
7362 promotes to int; it might be unsigned int.
7363 * data/yacc.c (yy_reduce_print): Likewise.
7365 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
7366 be #defined in the prologue, not in the Bison declarations.
7367 This fixes Debian Bug 102878, reported by Shaul Karl.
7369 2002-12-02 Paul Eggert <eggert@twinsun.com>
7371 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
7372 * lib/strtoul.c: New file, from gnulib.
7373 This fixes a porting bug reported by Peter Klein in
7374 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
7376 2002-11-30 Paul Eggert <eggert@twinsun.com>
7378 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
7379 and put only a forward declaration in the prologue. This is for
7380 consistency with the other scanner helper functions.
7382 Type clashes now generate warnings, not errors, since it
7383 appears that POSIX may allow some grammars with type clashes.
7384 * src/reader.c (grammar_current_rule_check): Warn about
7385 type clashes instead of complaining.
7386 * tests/input.at (Type Clashes): Expect warnings, not complaints.
7388 Add Yacc library, since POSIX requires it.
7389 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
7390 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
7391 * lib/main.c, lib/yyerror.c: New files.
7393 gram_error can be static; it need not be extern.
7394 * src/reader.h (gram_error): Remove decl.
7395 * src/parse-gram.y (gram_error): Now static. Add static decl.
7396 (print_token_value): Omit parameter names from forward decl,
7399 2002-11-29 Paul Eggert <eggert@twinsun.com>
7401 * doc/bison.texinfo: Emphasize that yylex and yyerror must
7402 be declared before being used. E.g., one should typically
7403 declare them in the prologue. Use GNU coding style in examples.
7404 Put "const" consistently after the type it modifies. Mention
7405 that C99 supports "inline". Mention that yyerror traditionally
7408 %parse-param and %lex-param now take just one argument, the
7409 declaration; the argument name is deduced from the declaration.
7411 * doc/bison.texinfo (Parser Function, Pure Calling, Error
7412 Reporting, Table of Symbols): Document this.
7413 * src/parse-gram.y (add_param): New function.
7415 (declaration): Implement new rule for %parse-param and %lex-param.
7416 * src/scan-gram.l: "," now elicits a warning, rather than being
7417 a token; this is more compatible with byacc.
7418 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
7420 2002-11-27 Paul Eggert <eggert@twinsun.com>
7422 Rename identifiers to avoid real and potential collisions.
7424 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
7425 to avoid collision with lex macro described by Bruce Lilly in
7426 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
7427 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
7428 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
7429 * src/parse-gram.y (print_token_value): Renamed from yyprint.
7431 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
7432 The name "yycontrol" violates the name space rules, and this stuff
7433 wasn't being used anyway.
7434 (input): Remove action; this stuff wasn't being used.
7435 (gram_error): Rename local variable yylloc -> loc.
7436 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
7437 (YY_DECL): Don't use "yy" at start of local variables.
7438 All uses changed, e.g., yylloc -> loc.
7439 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
7440 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
7441 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
7442 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
7444 * src/parse-gram.y (gram_error): loc is now const *.
7445 * src/reader.h (gram_error): Likewise.
7447 2002-11-24 Paul Eggert <eggert@twinsun.com>
7451 * tests/actions.at (Actions after errors): Use an output format
7452 more similar to that of the Printers and Destructors test.
7453 Test the position of the ';' token too.
7454 (Printers and Destructors): Likewise.
7455 (Printers and Destructors: %glr-parser): Remove for now, to avoid
7456 unnecessarily alarming people when the test fails.
7458 * data/yacc.c (yyerrlab1): Move this label down, so that the
7459 parser does not discard the lookahead token if the user code
7460 invokes YYERROR. This change is required for POSIX conformance.
7462 * lib/error.c: Sync with gnulib.
7464 2002-11-22 Paul Eggert <eggert@twinsun.com>
7466 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
7467 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
7468 * lib/xmalloc.c: Likewise.
7470 2002-11-20 Paul Eggert <eggert@twinsun.com>
7472 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
7474 2002-11-20 Paul Eggert <eggert@twinsun.com>
7476 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
7477 should use `if (! x) abort ();' rather than `assert (x);', and
7478 anyway it's one less thing to worry about configuring.
7480 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
7481 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
7482 and replace all instances of assert with abort.
7483 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
7484 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
7486 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
7487 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
7488 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
7489 hash_find_entry, hash_rehash, hash_insert): Likewise.
7490 * src/conflicts.c (resolve_sr_conflict): Likewise.
7491 * src/lalr.c (set_goto_map, map_goto): Likewise.

7498 symbol_pack): Likewise.
7499 * src/tables.c (conflict_row, pack_vector): Likewise.
7500 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,

7502 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
7503 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
7505 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
7506 (ARGMATCH_CONSTRAINT): New macro.
7507 (ARGMATCH_ASSERT): Use it.
7509 * src/system.h (verify): New macro.
7510 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
7512 * src/tables.c (tables_generate): Likewise.
7514 * src/struniq.c (struniq_assert): Now returns void, and aborts
7515 if the assertion is false.
7516 (struniq_assert_p): Remove.
7517 * src/struniq.h: Likewise.
7519 2002-11-18 Paul Eggert <eggert@twinsun.com>
7521 * data/glr.c (yygetLRActions): Replace `yyindex' with
7522 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
7523 This fixes the regression with Sun ONE Studio 7 cc that I reported in
7524 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
7526 2002-11-18 Akim Demaille <akim@epita.fr>
7528 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
7530 From Tim Van Holder.
7532 2002-11-17 Paul Eggert <eggert@twinsun.com>
7534 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
7535 to "SyntaxError" for consistency with my 2002-11-15 change.
7537 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
7538 not define to {}, since this breaks the common use of `YYDPRINTF
7539 ((...));' if a single statement is desired (e.g. before `else').
7540 Work around GCC warnings by surrounding corresponding calls with
7542 (yyhasResolvedValue): Remove unused function.
7543 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
7545 (yyreportSyntaxError): Renamed from yyreportParseError.
7546 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
7548 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
7549 extern when possible. Remove unused initializations.
7551 2002-11-16 Akim Demaille <akim@epita.fr>
7553 Augment the similarity between GLR and LALR traces.
7555 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
7556 (YY_REDUCE_PRINT): New.
7557 (yyparse): Use them.
7558 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
7560 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
7561 state reached after the reduction/recovery, since...
7562 (yyparse, yyprocessOneStack): Report the state we are entering in.
7564 2002-11-16 Akim Demaille <akim@epita.fr>
7566 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
7567 Add support for --trace=skeleton.
7568 * src/scan-skel.l: %option debug.
7569 Scan strings of non-@ or \n instead of character by character.
7570 (scan_skel): Handle trace_skeleton.
7572 (@output_parser_name@, @output_header_name@): ``Restore'' their
7573 support (used to be M4 macros).
7574 * data/yacc.c: Quote larger chunks, a la glr.c.
7575 * data/lalr1.cc: Likewise.
7576 The header guards are no longer available, so use some other
7577 string than `YYLSP_NEEDED'.
7579 2002-11-16 Akim Demaille <akim@epita.fr>
7581 Make the ``Printers and Destructors'' test more verbose, taking
7582 `yacc.c''s behavior as (possibly wrong) reference.
7584 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
7585 instead of fprint on stdout.
7586 Set and report the last_line of the symbols.
7587 Consistently display values and locations.
7589 2002-11-16 Paul Eggert <eggert@twinsun.com>
7591 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
7593 2002-11-15 Paul Eggert <eggert@twinsun.com>
7595 * tests/actions.at (Actions after errors): New test case.
7597 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
7598 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
7599 tests/action.at, tests/calc.at, tests/conflicts.at,
7600 tests/cxx-type.at, tests/regression.at:
7601 "parse error" -> "syntax error" for POSIX compatibility.
7602 "parsing stack overflow..." -> "parser stack overflow" so
7603 that code matches Bison documentation.
7605 2002-11-15 Akim Demaille <akim@epita.fr>
7607 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
7608 take two BRACED_CODE, not two string_content.
7609 Free the scanner's obstack when we are done.
7610 (code_content): New.
7611 * tests/calc.at: Adjust.
7612 * doc/bison.texinfo: Adjust.
7613 Also, make sure to include the `,' for these declarations.
7615 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
7617 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
7618 definition; avoids potential autoreconf problems.
7620 2002-11-15 Akim Demaille <akim@epita.fr>
7622 Always check the value returned by yyparse.
7624 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
7625 returned by yyparse.
7626 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
7628 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
7629 returned by yyparse.
7631 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>

7636 2002-11-14 Paul Eggert <eggert@twinsun.com>
7638 * src/output.c (output_skeleton): Call xfopen instead of
7639 duplicating xfopen's body.
7641 Fix bugs reported by Nelson H. F. Beebe in
7642 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
7644 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
7645 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
7646 Group compiler. Instead, use "$CC -E bar.c". Include the .h
7647 file twice in the grammar, as an extra check.
7649 * tests/input.at (Torturing the Scanner): Surround the
7650 backslash-newline tests with "#if 0", to make it less likely that
7651 we'll run into compiler bugs. Bring back solitary \ inside
7652 comment, but add a closing comment to work around HP C bug. Don't
7653 test backslash-newline in C character constant.
7655 2002-11-14 Akim Demaille <akim@epita.fr>
7657 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
7658 status of the compiler.
7659 Calling `exit 1' is no longer needed.
7660 Reported by Nelson H. F. Beebe.
7662 2002-11-14 Akim Demaille <akim@epita.fr>
7664 * tests/atlocal.in (CPPFLAGS): We have config.h.

7677 * doc/bison.texinfo: Various formatting changes (alignments in
7678 samples, additional @group/@end group, GCS in samples.
7679 Use @deffn instead of simple @table to define the directives,
7680 macros, variables etc.
7682 2002-11-13 Paul Eggert <eggert@twinsun.com>
7684 Fix some bugs reported by Albert Chin-A-Young in
7685 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
7687 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
7688 -o c"; the HP C compiler chatters during compilation.
7689 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
7690 * tests/headers.at (export YYLTYPE): Likewise.
7692 * tests/input.at (Torturing the Scanner): Remove lines containing
7693 solitary backslashes, as they tickle a bug in the HP C compiler.
7695 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
7696 comments, since they're not portable. Use GNU coding style.
7698 2002-11-13 Akim Demaille <akim@epita.fr>
7700 * data/yacc.c: Leave bigger chunks of quoted text.
7701 (YYDSYMPRINTF): New.

7710 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
7711 (yyglrReduce): Return yyok, not 0.
7712 This should avoid the enumerated-type warnings reported
7713 by Nelson H. F. Beebe in

7716 * lib/bbitset.h (BITSET_INLINE): Remove.
7717 * lib/bitset.h [! BITSET_INLINE]: Remove.
7718 (bitset_set, bitset_reset, bitset_test): Rename local vars
7719 to avoid shadowing warnings by GCC.
7721 * data/glr.c (inline): Remove #define. It's the user's
7722 responsibility to #define it away, just like 'const'.
7723 This fixes one of the bugs reported by Nelson H. F. Beebe in
7724 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
7726 * Makefile.maint (po-check): Scan .l and .y files instead of the
7727 .c and the .h files that they generate. This fixes the bug
7728 reported by Tim Van Holder in:
7729 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
7730 Look for N_ as well as for _. Try to avoid matching #define for
7732 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
7733 src/system.h. Add src/parse-gram.y, src/scan-gram.l.

7735 do not confuse xgettext.
7737 * src/struniq.h (struniq_new): Do not declare the return type
7738 to be 'const'; this violates the C standard.
7739 * src/struniq.c (struniq_new): Likewise.
7741 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
7743 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the

7775 * data/glr.c (yystos): New.
7776 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
7778 (yyval): Don't define it, it is handled via M4.
7779 (yyrecoverParseError): Free verbosely the discarded symbols.
7780 * data/yacc.c (yysymprint): Remove, rather...
7781 (b4_yysymprint_generate): invoke.
7782 * data/c.m4 (b4_yysymprint_generate): New.
7783 Accept pointers as arguments, as opposed to the version from

7792 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
7793 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
7794 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
7795 it against YYEMPTY and so forth), work on yytoken (i.e., set
7796 it to YYEMPTY etc.).
7797 (yydestruct): Replace with a b4_yydestruct_generate invocation.
7798 (b4_symbol_actions): Remove.
7799 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands

7806 2002-11-12 Akim Demaille <akim@epita.fr>

7868 * src/main.c (main): Call struniqs_new early enough to use it for
7870 Don't free the input file name.
7872 2002-11-12 Akim Demaille <akim@epita.fr>
7874 * src/symtab.c (symbol_free): Remove dead deactivated code:
7875 type_name are properly removed.

7885 2002-11-11 Paul Eggert <eggert@twinsun.com>
7887 Revamp to fix many (but not all) of the C- and M4-related quoting
7888 problems. Among other things, this fixes the Bison bug reported
7889 by Jan Hubicka when processing the Bash grammar; see:
7890 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
7892 Use new @ escapes consistently. Represent brackets with @{ and @}
7893 rather than @<:@ and @:>@, since this works a bit better with dumb
7894 editors like vi. Represent @ with @@, since @ is now consistently
7895 an escape. Use @oline@ and @ofile@ rather than __oline__ and
7896 __ofile__, to avoid unexpected expansions. Similarly, use @output
7897 rather than #output.
7899 * data/c.m4 (b4_copyright): Omit file name from comment, since
7900 the file name could contain "*/".
7901 (b4_synclines_flag): Don't quote the 2nd argument; it should already
7902 be quoted. All uses changed.
7904 * data/glr.c: Use new @ escapes consistently.
7905 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
7906 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
7907 Remove, since they couldn't handle arbitrary characters in file
7909 * data/lalr1.cc: Likewise.
7910 * data/yacc.c: Likewise.
7912 * src/files.c (output_infix): Remove; all uses removed.
7913 * src/files.h: Likewise.
7915 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
7916 mishandled funny characters in file names, and anyway it isn't
7918 * data/yacc.c: Likewise.
7919 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
7921 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
7922 * data/yacc.c: Likewise.
7924 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
7926 (muscle_init): Quote filename as a C string.
7927 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
7928 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
7929 * src/output.c (escaped_file_name_output): New function.
7930 (prepare_symbols): Quote tokens for M4.
7931 (prepare): Don't insert output_infix, output_prefix,
7932 output_parser_name, output_header_name; this is now down by scan-skel.
7933 Insert skeleton as a C string.
7935 * src/output.c (user_actions_output, symbol_destructors_output,
7936 symbol_printers_output): Quote filenames for C and M4.
7937 * src/reader.c (prologue_augment, epilogue_set): Likewise.
7939 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
7940 escapes other than \\ and \'; this simplifies the code.
7941 (<SC_STRING>): Likewise, for \\ and \".
7942 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
7943 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
7944 Use new escapes @{ and @} for [ and ].
7946 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
7947 them with auto vars.
7948 Switch to new escape scheme, where @ is the escape character uniformly.
7949 Abort if a stray escape character is found. Avoid unbounded input
7950 buffer when parsing non-escaped text.
7952 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
7953 __oline__, #output, $@, and @{ do not have unintended meanings.
7955 2002-11-09 Paul Eggert <eggert@twinsun.com>
7957 Fix the test failure due to GCC warnings described in
7958 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
7959 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
7960 evaluate to 0 if it's impossible for NINF to be in the respective
7962 (yygetLRActions, yyrecoverParseError): Use them.
7964 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
7965 counted in the token inserted at end of file. Now takes
7966 location_t *, not location_t, so that the location can be
7967 adjusted. All uses changed.
7969 * tests/regression.at (Invalid inputs): Adjust wording in
7970 diagnostic to match the new behavior.
7972 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
7973 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
7974 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
7975 abort ();'. This reduces the runtime of the "Many lookaheads"
7976 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
7979 2002-11-07 Paul Eggert <eggert@twinsun.com>
7981 * src/parse-gram.y (CHARACTER): Remove unused token.
7984 * src/scan-gram.l: Remove stack option. We no longer use the
7985 stack, since the stack was never deeper than 1; instead, use the
7986 new auto var c_context to record the stacked value.
7988 Remove nounput option. At an unexpected end of file, we now unput
7989 the minimal input necessary to end cleanly; this simplifies the
7992 Avoid unbounded token sizes where this is easy.
7994 (unexpected_end_of_file): New function.
7995 Use it to systematize the error message on unexpected EOF.
7996 (last-string): Now auto, not static.
7997 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
7998 (scanner_last_string_free): Remove; not used.
7999 (percent_percent_count): Move decl to just before use.
8000 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
8001 not the (never otherwised-used) CHARACTER.
8003 2002-11-07 Akim Demaille <akim@epita.fr>
8005 Let yyerror always receive the msg as last argument, so that
8006 yyerror can be variadic.
8008 * data/yacc.c (b4_yyerror_args): New.
8009 Use it when calling yyerror.
8010 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.

8016 2002-11-06 Akim Demaille <akim@epita.fr>
8018 #line should have quoted strings.
8019 Ideally, this should be done by m4_quotearg.
8021 * src/scan-skel.l: Include quotearg.h.
8023 * src/output.c (symbol_printers_output)
8024 (symbol_destructors_output): Quote the file name.
8026 2002-11-06 Akim Demaille <akim@epita.fr>

8043 2002-11-06 Akim Demaille <akim@epita.fr>
8045 * src/main.c (main): Free `infile'.
8046 * src/scan-gram.l (handle_syncline): New.
8048 * src/output.c (user_actions_output, symbol_destructors_output)
8049 (symbol_printers_output): Use the location's file name, not
8051 * src/reader.c (prologue_augment, epilogue_set): Likewise.
8053 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
8055 * src/tables.c (matching_state): Don't allow states to match if
8056 either has GLR conflict entries.
8058 2002-11-05 Paul Eggert <eggert@twinsun.com>
8060 * src/scan-gram.l: Use more accurate diagnostics, e.g.
8061 "integer out of range" rather than "invalid value".
8062 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
8065 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
8066 Also, remove one static variable in the scanner.
8068 * src/scan-gram.l (braces_level): Now auto, not static.
8069 Initialize to zero if the compiler is being picky.
8070 (INITIAL): Clear braces_level instead of incrementing it.
8071 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
8072 as POSIX 1003.1-2001 requires.
8073 * src/system.h (IF_LINT): New macro, taken from coreutils.
8074 * configure.ac: Define "lint" if --enable-gcc-warnings.
8076 2002-11-05 Akim Demaille <akim@epita.fr>
8078 * src/scan-gram.l: When it starts with `%', complain about the
8079 whole directive, not just that `invalid character: %'.
8081 2002-11-04 Akim Demaille <akim@epita.fr>
8083 * Makefile.maint: Update from Autoconf.
8084 (update, cvs-update, po-update, do-po-update): New.
8086 2002-11-04 Akim Demaille <akim@epita.fr>
8088 * tests/glr-regr1.at (Badly Collapsed GLR States): Prototype yylex
8090 Have yyerror `use' its arguments.
8091 * tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF
8092 returns true when location & yacc & pure & parse-param.
8093 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
8095 2002-11-04 Akim Demaille <akim@epita.fr>
8097 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
8099 * src/scan-gram.l: Use [\'] instead of ['] to pacify
8102 Use quote, not quote_n since LOCATION_PRINT no longer uses the
8105 2002-11-03 Paul Eggert <eggert@twinsun.com>
8107 * src/reader.c (get_merge_function, grammar_current_rule_check):
8108 Use consistent diagnostics for reporting type name clashes.
8109 Quote the types with <>, for consistency with Yacc.
8110 * tests/input.at (Type Clashes): Adjust to diagnostic changes.

8121 (b4_user_formals, b4_pure_args, b4_pure_formals, b4_lpure_args)
8122 (b4_lpure_formals): New.
8123 Use b4_identification.
8124 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
8125 b4_user_formals and b4_user_args.
8126 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
8127 (yyreportAmbiguity): When using a pure parser, also need
8128 the location, and the parse-params.
8130 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
8131 When using a pure parser, also need the parse-params.
8133 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
8134 (%pure-parser + %parse-param) LALR and GLR parsers.
8135 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
8136 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
8137 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
8138 (_AT_DATA_CALC_Y): Equip for purity of yyerror.
8139 (_AT_CHECK_CALC_ERROR): Use AT_YYERROR_SEES_LOC_IF.
8140 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Equip for yyerror purity.
8141 * doc/bison.texinfo: Untabify the whole file.
8142 (Parser Function): Document %parse-param, deprecate YYPARSE_PARAM.
8143 (Pure Calling): Document %lex-param, deprecate YYLEX_PARAM.
8144 (Error Reporting): Adjust to these new directives.
8145 Document %error-verbose, deprecate YYERROR_VERBOSE.
8147 2002-11-03 Akim Demaille <akim@epita.fr>
8149 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
8150 AT_CHECK_CALC_GLR invocations to use % directives, instead of
8151 command line options.
8152 * tests/cxx-type.at: Formatting changes.
8154 2002-11-03 Paul Eggert <eggert@twinsun.com>
8156 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
8157 to count columns correctly, and to check for invalid inputs.
8159 Use mbsnwidth to count columns correctly. Account for tabs, too.
8161 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
8162 (extend_location): New function.
8165 Handle CRLF in C code rather than in Lex code.
8166 (YY_INPUT): New macro.
8167 (no_cr_read): New function.
8169 Scan UCNs, even though we don't fully handle them yet.
8170 (convert_ucn_to_byte): New function.
8172 Handle backslash-newline correctly in C code.
8173 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
8174 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
8176 (tag, splice): New EREs. Do not allow NUL or newline in tags.
8177 Use {splice} wherever C allows backslash-newline.
8178 YY_STEP after space, newline, vertical-tab.
8179 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
8181 (letter, id): Don't assume ASCII; e.g., spell out a-z.
8183 ({int}, handle_action_dollar, handle_action_at): Check for integer
8186 (YY_STEP): Omit trailing semicolon, so that it's more like C.
8188 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
8189 as well as \000. Check for UCHAR_MAX, not 255.
8190 Allow \x with an arbitrary positive number of digits, as in C.
8191 Check for overflow here.
8192 Allow \? and UCNs, for compatibility with C.
8194 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
8195 with quote slot used by complain_at.
8197 * tests/input.at: Add tests for backslash-newline, m4 quotes
8198 in symbols, long literals, and funny escapes in strings.
8200 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
8201 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
8202 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
8203 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.

8214 2002-11-02 Paul Eggert <eggert@twinsun.com>
8216 * src/reader.c: Don't include quote.h; not needed.
8217 (get_merge_function): Reword warning to be consistent with
8218 type clash diagnostic in grammar_current_rule_check.
8220 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
8221 bug in trigraph handling.
8223 * src/output.c (prepare_symbols): When printing token names,
8224 escape "[" as "@<:@" and likewise for "]".
8226 * src/system.h (errno): Remove declaration, as we are now
8227 assuming C89 or better, and C89 guarantees errno.
8229 2002-10-30 Paul Eggert <eggert@twinsun.com>
8231 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
8232 Check for close failures.
8233 * src/files.h (xfclose): Return void, not int, since it always
8235 * src/files.c (xfclose): Likewise. Report I/O error if ferror
8237 * src/output.c (output_skeleton): Use xfclose rather than fclose
8238 and ferror. xfclose now checks ferror.
8240 * data/glr.c (YYLEFTMOST_STATE): Remove.
8241 (yyreportTree): Use a stack-based leftmost state. This avoids
8242 our continuing battles with bogus warnings about initializers.
8244 2002-10-30 Akim Demaille <akim@epita.fr>
8246 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
8249 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
8251 * tests/glr-regr1.at: New test for reported regressions.
8252 * tests/testsuite.at: Add glr-regr1.at test.
8253 * tests/Makefile.am: Add glr-regr1.at test.
8255 2002-10-24 Paul Eggert <eggert@twinsun.com>
8259 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
8260 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
8261 we use malloc. Don't assume 'A' through 'Z' are contiguous.
8262 Don't assume strdup exists; POSIX says its an XSI extension.
8263 Check for buffer overflow on input.
8265 2002-10-24 Akim Demaille <akim@epita.fr>
8267 * src/output.c (output_skeleton): Don't disable M4sugar comments
8268 too soon: it results in comments being expanded.
8269 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
8272 2002-10-24 Akim Demaille <akim@epita.fr>
8274 * data/yacc.c (m4_int_type): New.
8275 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
8276 char' as only yacc.c wants K&R portability.
8277 * data/glr.c (yysigned_char): Remove.
8278 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
8279 Reported by Quoc Peyrot.
8281 2002-10-23 Paul Eggert <eggert@twinsun.com>
8283 * src/main.c (main): With --trace=time, report times even if a
8284 non-fatal error occurs. Formerly, the times were reported in some
8285 such cases but not in others.
8286 * src/reader.c (reader): Just return if a complaint has been issued,
8287 instead of exiting, so that 'main' can report times.
8289 2002-10-22 Akim Demaille <akim@epita.fr>
8291 * src/system.h: Include sys/types.
8292 Reported by Bert Deknuydt.
8294 2002-10-23 Paul Eggert <eggert@twinsun.com>
8296 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
8297 Suggested by Art Haas.
8299 2002-10-22 Paul Eggert <eggert@twinsun.com>
8301 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
8302 decl; not needed any more.
8303 * src/main.c (main): Use return to exit, undoing yesterday's change.
8304 The last OS that we could find where this wouldn't work is
8305 SunOS 3.5, and that's too old to worry about now.
8307 * data/glr.c (struct yyltype): Define members even when not
8308 doing locations. This is more consistent with yacc.c, and it
8309 works around the following bug reports:
8310 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
8311 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
8313 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
8314 @acronym consistently. Standardize on "Yacc" instead of "YACC",
8315 "Algol" instead of "ALGOL". Give a bit more history about BNF.
8317 2002-10-22 Akim Demaille <akim@epita.fr>
8321 2002-10-21 Paul Eggert <eggert@twinsun.com>
8323 Be consistent about 'bool'; the old code used an enum in one
8324 module and an int in another, and this violates the C standard.
8325 * m4/stdbool.m4: New file, from coreutils 4.5.3.
8326 * configure.ac (AC_HEADER_STDBOOL): Add.
8327 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
8328 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
8329 * src/symtab.c (hash_compare_symbol_t): Likewise.
8330 * src/system.h (bool, false, true): Use a definition consistent
8331 with ../lib/hash.c. All uses changed.
8333 * src/complain.c (warning_issued): Renamed from warn_message_count,
8334 so that we needn't worry about integer overflow (!).
8335 Now of type bool. All uses changed.
8336 (complaint_issued): Renamed from complain_message_count; likewise.
8338 * src/main.c (main): Use exit to exit with failure.
8340 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
8341 rather than 1 and 0.
8342 * src/main.c (main): Likewise.
8343 * src/getargs.c (getargs): Likewise.
8344 * src/reader.c (reader): Likewise.
8346 * src/getarg.c (getargs): Remove duplicate code for
8347 "Try `bison --help'".
8349 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
8350 What was that "2" for?
8352 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
8353 * src/getargs.c (usage): Likewise.
8355 * src/getargs.c (getargs): When there are too few operands, report
8356 the last one. When there are too many, report the first extra
8357 one. This is how diffutils does it.
8359 2002-10-20 Paul Eggert <eggert@twinsun.com>
8361 Remove K&R vestiges.
8362 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.

8366 fatal): Assume prototypes.
8367 * src/complain.h: Assume prototypes.
8368 * src/system.h (PARAMS): Remove.
8369 Include <limits.h> unconditionally, since it's guaranteeed even
8370 for a freestanding C89 compiler.
8371 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
8372 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.

8389 (b4_c_function_def): this.
8390 (b4_c_function_decl, b4_c_ansi_function_def)
8391 (b4_c_ansi_function_decl): New.
8392 Change the interpretation of the arguments: before `int, foo', now

8395 Adjust b4_c_function_def uses.
8396 * data/glr.c (yyparse): Likewise, but ANSI only.

8400 * src/output.c (prepare): Move the definition of `tokens_number',
8401 `nterms_number', `undef_token_number', `user_token_number_max'
8403 (prepare_tokens): Here.
8404 (prepare_tokens): Rename as...
8405 (prepare_symbols): this.
8406 (prepare): Move the definition of `rules_number' to...
8407 (prepare_rules): here.

8430 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
8433 2002-10-19 Paul Eggert <eggert@twinsun.com>
8435 Do not create a temporary file, as that involves security and
8436 cleanup headaches. Instead, use a pair of pipes.
8437 Derived from a suggestion by Florian Krohm.
8438 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
8439 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
8440 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
8441 (BISON_PREREQ_SUBPIPE): Add.

8446 * src/output.c: Include "subpipe.h".
8447 (m4_invoke): Remove decl.
8448 (scan_skel): New decl.
8449 (output_skeleton): Use pipe rather than temporary file for m4 input.
8450 Check that m4sugar.m4 is readable, to avoid deadlock.
8451 Check for pipe I/O error.
8452 * src/scan-skel.l (readpipe): Remove decl.
8453 (scan_skel): New function, to be used in place of m4_invoke.
8454 Read from stream rather than file.
8456 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
8457 float, as this generates a warning on Solaris 8 + GCC 3.2 with
8458 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
8459 this generates a more-accurate value anyway.
8461 * lib/timevar.c (timervar_accumulate): Rename locals to
8462 avoid confusion with similarly-named more-global.
8463 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
8465 * src/output.c (prepare): Use xstrdup to convert char const *
8466 to char *, to avoid GCC warning.
8468 2002-10-19 Akim Demaille <akim@epita.fr>
8470 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
8471 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
8472 Use them to have `calc.y' ready for %pure-parser.
8473 * data/yacc.c (YYLEX): Pass a yylex return type to
8476 2002-10-19 Akim Demaille <akim@epita.fr>
8478 Prototype support of %lex-param and %parse-param.
8480 * src/parse-gram.y: Add the definition of the %lex-param and
8481 %parse-param tokens, plus their rules.
8482 Drop the `_' version of %glr-parser.
8484 * src/scan-gram.l (INITIAL): Scan them.
8485 * src/muscle_tab.c: Comment changes.
8486 (muscle_insert, muscle_find): Rename `pair' as `probe'.

8488 (muscle_entry_s): The `value' member is no longer const.
8489 Adjust all dependencies.
8490 * src/muscle_tab.c (muscle_init): Adjust: use
8491 MUSCLE_INSERT_STRING.
8492 Initialize the obstack earlier.
8493 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
8494 (muscle_pair_list_grow): New.
8495 * data/c.m4 (b4_c_function_call, b4_c_args): New.

8498 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
8500 2002-10-19 Akim Demaille <akim@epita.fr>
8502 * src/getargs.c (usage): Take status as argument and exit
8504 Report the traditional `Try ... --help' message when status != 0.
8505 (usage, version): Don't take a FILE * as arg, it is pointless.
8506 (getargs): When there is an incorrect number of arguments, make it
8507 an error, and report it GNUlically thanks to `usage ()'.
8509 2002-10-18 Paul Eggert <eggert@twinsun.com>
8511 * data/glr.c (yyreportParseError): Don't assume that sprintf
8512 yields the length of the printed string, as this is not true
8513 on SunOS 4.1.4. Reported by Peter Klein.
8515 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
8516 * tests/conflicts.at (%nonassoc and eof): Likewise.
8517 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
8519 2002-10-17 Akim Demaille <akim@epita.fr>
8521 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
8522 * src/getargs.c (trace_types, trace_args): Adjust.
8523 * src/reader.c (grammar_current_rule_prec_set)
8524 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
8525 Standardize error messages.
8527 (reader): Use trace_flag to enable scanner/parser debugging,
8528 instead of an adhoc scheme.
8529 * src/scan-gram.l: Remove trailing debugging code.
8531 2002-10-16 Paul Eggert <eggert@twinsun.com>
8533 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
8536 * NEWS: Officially drop support for building Bison with K&R C,
8537 since it didn't work anyway and it's not worth worrying about.
8538 * Makefile.maint (wget_files): Remove ansi2knr.c.
8539 (ansi2knr.c-url_prefix): Remove.
8540 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
8541 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
8542 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
8544 2002-10-15 Paul Eggert <eggert@twinsun.com>
8546 Stop using the "enum_" trick for K&R-style function definitions;
8547 it confused me, and I was the author! Instead, assume that people
8548 who want to use K&R C compilers (when using these modules in GCC,
8549 perhaps?) will run ansi2knr.
8551 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
8552 All uses of "enum_" changed to "enum ".
8553 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.

8564 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
8565 Use function prototypes; this removes the need for declaring
8566 static functions simply to provide their prototypes.
8567 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

8633 2002-10-14 Akim Demaille <akim@epita.fr>
8635 * src/tables.c (table_ninf_remap): base -> tab.
8636 Reported by Matt Rosing.
8638 2002-10-14 Paul Eggert <eggert@twinsun.com>
8640 * tests/action.at, tests/calc.at, tests/conflicts.at,
8641 tests/cxx-type.at, tests/headers.at, tests/input.at,
8642 tests/regression.at, tests/synclines.at, tests/torture.at:
8643 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
8644 so that the tests still work even if POSIXLY_CORRECT is set.
8645 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
8647 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
8648 for portability to K&R hosts. Fix typo: signed char is guaranteed
8649 only to 127, not to 128.
8650 * data/glr.c (yysigned_char): New type.
8651 * data/yacc.c (yysigned_char): Likewise.
8652 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
8654 2002-10-13 Paul Eggert <eggert@twinsun.com>
8656 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
8657 true due to limited range of data type" warning from GCC.
8659 * data/c.m4 (b4_token_defines): Protect against double-inclusion
8660 by wrapping enum yytokentype's definition inside #ifndef
8661 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
8663 2002-10-13 Akim Demaille <akim@epita.fr>
8665 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
8666 Un yy- yyrhs to avoid the name clash with the global YYRHS.
8668 2002-10-13 Akim Demaille <akim@epita.fr>
8670 * Makefile.maint: Update from Autoconf 2.54.
8671 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
8673 2002-10-13 Akim Demaille <akim@epita.fr>
8675 * src/print.c (print_state): Separate the list of solved conflicts
8676 from the other items.
8677 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
8679 2002-10-13 Akim Demaille <akim@epita.fr>
8681 Let nondeterministic skeletons be usable with deterministic
8684 With the patch, GAWK compiled by GCC without -O2 passes its test
8685 suite using a GLR parser driven by LALR tables. It fails with -O2
8686 because `struct stat' gives two different answers on my machine:
8687 88 (definition of an auto var) and later 96 (memset on this var).
8688 Hence the stack is badly corrumpted. The headers inclusion is to
8689 blame: if I move the awk.h inclusion before GLR's system header
8690 inclusion, the two struct stat have the same size.
8692 * src/tables.c (pack_table): Always create conflict_table.
8693 (token_actions): Always create conflict_list.
8694 * data/glr.c (YYFLAG): Remove, unused.
8696 2002-10-13 Akim Demaille <akim@epita.fr>
8698 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
8700 (VALGRIND, GXX): New.
8701 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
8702 * tests/bison.in: Run $PREBISON a pre-command.
8703 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
8704 (maintainer-check-g++): New.
8705 * Makefile.am (maintainer-check): New.
8707 2002-10-13 Akim Demaille <akim@epita.fr>
8709 * data/glr.c: Formatting changes.
8710 Tweak some trace messages to match yacc.c's.
8712 2002-10-13 Akim Demaille <akim@epita.fr>
8714 GLR parsers sometimes raise parse errors instead of performing the
8716 Reported by Charles-Henry de Boysson.
8718 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
8719 check the length of the traces when %glr.
8720 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
8722 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
8724 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
8725 (yyltype): Remove the yy prefix from the member names.
8726 (yytable): Complete its comment.
8727 (yygetLRActions): Map error action number from YYTABLE from
8729 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
8730 (which was a bug: it should have been YYTABEL_NINF, and yet it was
8731 not satisfying as we could compare an YYACTION computed from
8732 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
8733 only value for error actions.
8734 (yyreportParseError): In verbose parse error messages, don't issue
8735 `error' in the list of expected tokens.
8736 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
8737 next action to perform to match glr.c's decoding.
8738 (yytable): Complete its comment.
8740 2002-10-13 Paul Eggert <eggert@twinsun.com>
8742 Fix problem reported by Henrik Grubbstroem in
8743 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
8744 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
8745 because the Bison parser reads the second action before reducing
8747 * src/scan-gram.l (rule_length): New static var.
8748 Use it to keep track of the rule length in the scanner, since
8749 we can't expect the parser to be in lock-step sync with the scanner.
8750 (handle_action_dollar, handle_action_at): Use this var.
8751 * tests/actions.at (Exotic Dollars): Test for the problem.
8753 2002-10-12 Paul Eggert <eggert@twinsun.com>
8755 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
8756 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
8757 Include <sys/time.h> when checking for clock_t and struct tms.
8758 Use same include order as source.
8759 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
8760 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
8762 * lib/timevar.c: Update copyright date and clarify comments.
8763 (get_time) [IN_GCC]: Keep the GCC version for reference.
8765 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
8766 GCC version as of today, then merge Bison's changes.
8767 Change "GCC" to "Bison" in copyright notice. timevar.def's
8768 author is Akim, so change that too.
8770 * src/reader.c (grammar_current_rule_check):
8771 Don't worry about the default action if $$ is untyped.
8772 Prevents bogus warnings reported by Jim Gifford in
8773 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
8775 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
8776 * data/glr.c, data/lalr1.cc, data/yacc.c:

8783 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
8784 (yyparse): here. This undoes some of the 2002-07-25 change.
8785 Compatibility problem reported by Ralf S. Engelschall with

8799 2002-10-10 Paul Eggert <eggert@twinsun.com>
8801 Portability fixes for bitsets; this also avoids several GCC
8804 * lib/abitset.c: Include <stddef.h>, for offsetof.
8805 * lib/lbitset.c: Likewise.
8807 * lib/abitset.c (abitset_bytes): Return a size that is aligned
8808 properly for vectors of objects. Do not assume that adding a
8809 header size to a multiple of a word size yields a value that is
8810 properly aligned for the whole union.
8811 * lib/bitsetv.c (bitsetv_alloc): Likewise.
8813 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
8814 unique names for structures.
8815 * lib/ebitset.c (ebitset_bytes): Likewise.
8816 * lib/lbitset.c (lbitset_bytes): Likewise.
8818 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
8819 abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
8820 abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,

8822 abitset_xor_cmp, abitset_and_or, abitset_and_or_cmp,
8823 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
8824 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
8825 to improve the type-checking that GCC can do.
8826 * lib/bitset.c (bitset_op4_cmp): Likewise.
8827 * lib/bitset_stats.c (bitset_stats_count,
8828 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
8829 bitset_stats_copy, bitset_stats_disjoint_p,

8843 * lib/ebitset.h: Likewise.
8844 * lib/lbitset.h: Likewise.
8846 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
8847 All instances of parameters of type enum bitset_opts are now of
8848 type enum_bitset_opts, to conform to the C Standard, and similarly
8849 for enum_bitset_type.
8850 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
8851 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
8853 Do not use "struct bitset_struct" to mean different things in
8854 different modules. Not only is this confusing, it violates
8855 the C Standard, which requires that structure types in different
8856 modules must be compatible if one is to be passed to the other.
8857 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
8858 All instances of "struct bitset_struct *" replaced with "bitset".
8859 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
8860 (union bitset_union, struct abitset_struct, struct ebitset_struct,
8861 struct lbitset_struct, struct bitset_stats_struct): New types.
8862 All uses of struct bitset_struct changed to union bitset_union,

8865 struct bitset_struct): Remove.
8866 * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
8867 struct bitset_struct): Remove.
8868 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
8869 bitset_struct): Remove.
8870 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
8873 Do not call a function of type T using a call that assumes the
8874 function is of a different type U. Standard C requires that a
8875 function must be called with a type that is compatible with its
8877 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
8879 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
8881 * lib/ebitset.c (PFV): Remove.

8886 (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
8887 (ebitset_vtable): Use them.
8888 * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
8889 lbitset_xor): New functions.
8890 (lbitset_vtable): Use them.
8892 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
8895 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
8897 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
8898 Use offsetof, for simplicity.
8900 2002-10-06 Paul Eggert <eggert@twinsun.com>
8902 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
8903 the same width as int. This reapplies a hunk of the 2002-08-12 patch
8904 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
8905 which was inadvertently undone by the 2002-09-30 patch.
8906 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
8907 the same width as int.
8909 2002-10-04 Paul Eggert <eggert@twinsun.com>
8913 * configure.ac (AC_INIT), NEWS: Increment version number.
8915 * doc/bison.texinfo: Minor spelling, grammar, and white space
8917 (Symbols): Mention that any negative value returned from yylex
8918 signifies end-of-input. Warn about negative chars. Mention
8919 the portable Standard C character set.
8921 The GNU coding standard says CFLAGS and YFLAGS are reserved
8922 for the installer to set.
8923 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
8924 * src/Makefile.am (AM_CFLAGS): Likewise.
8925 (AM_YFLAGS): Renamed from YFLAGS.
8927 Fix some MAX and MIN problems.
8928 * src/gram.h (ITEM_NUMBER_MIN): MIN_MAX -> INT_MIN.
8929 * src/lalr.h (GOTO_NUMBER_MAX): INT_MAX -> SHRT_MAX.
8930 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
8931 * src/reader.c (reader): Use it.
8933 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
8934 POSIX 1003.1-2001 has removed fgrep.
8936 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>
8938 * lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
8939 interpreted as signed.
8940 * lib/ebitset.c (ebitset_list): Fix bug.
8942 2002-10-01 Paul Eggert <eggert@twinsun.com>

9005 * lib/bbitset.h (BITSET_BINDEX_MAX, BITSET_WINDEX_MAX,
9006 BITSET_SIZE_MAX): New macros.
9007 (BITSET_INDEX_MAX): Remove. It wasn't right, since it assumed that

9011 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
9012 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,

9167 as int, and similarly for yyposn and YYINDEX.

9265 outside the C locale.
9267 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
9268 this is a GCC extension and is not portable to other compilers.

9271 Do not include <ctype.h>; no longer needed.
9272 Do not include <malloc.h>; no longer needed (and generates

9282 exit status as failure, not just exit status 1. Sun C exits

9330 * src/print.c, src/print_graph.c, src/tables.c: Adjust.
9332 2002-08-01 Akim Demaille <akim@epita.fr>

9450 different: save its reduction (accept) instead of having a state

9505 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
9507 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
9508 for the time being: %locations ought to provide it to yyerror.
9510 2002-07-25 Akim Demaille <akim@epita.fr>
9512 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

11209 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
11210 full stderr, and strip it according to the bison options, instead
11211 of composing the error message from different bits.

11213 Adjust all the invocations.
11214 Add an invocation exercising the error token.
11215 Add an invocation demonstrating a stupid error message.
11216 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.

11276 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
11277 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
11278 passes, but produces negative #line number, once fixed, GCC is

11481 * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
11482 lacking `+ 1' to nrules, Bison reported as useless a token if it
11483 was used solely to set the precedence of the last rule...
11485 2002-04-07 Akim Demaille <akim@epita.fr>
11487 * data/bison.c++, data/bison.simple: Don't output the current file
11488 name in #line, to avoid useless diffs between two identical
11489 outputs under different names.

11493 * src/closure.c, src/print.c, src/reader.c, src/reduce.c:

11509 * src/reader.c, src/reduce.c: Let rule_t.rhs point directly to the
11510 RHS, instead of being an index in RITEMS.

11682 * src/print.c (print_reductions): Use bitset_and, bitset_andn.
11683 * src/reduce.c (useless_nonterminals): Formatting changes.
11684 * src/warshall.c (TC): Use bitset_or.
11686 2002-03-04 Akim Demaille <akim@epita.fr>
11688 * src/lalr.h, src/lalr.c (tokensetsize): Remove, unused.
11689 * src/system.h (BITS_PER_WORD, WORDSIZE, SETBIT, RESETBIT, BITISSET):

11694 * src/lalr.c (F): Now a bitset*.
11695 Adjust all dependencies.
11697 2002-03-04 Akim Demaille <akim@epita.fr>
11699 * src/conflicts.c (shiftset, lookaheadset): Now bitset.
11700 Adjust all dependencies.
11702 2002-03-04 Akim Demaille <akim@epita.fr>
11704 * src/L0.c, src/LR0.h (nstates): Be size_t.
11705 Adjust comparisons (signed vs unsigned).

11713 Adjust all dependencies.
11714 (varsetsize): Remove, now unused.

11719 * src/print.c: Convert to use bitset.h, not hand coded iterations
11722 2002-03-04 Akim Demaille <akim@epita.fr>
11724 * src/reduce.c: Convert to use bitset.h, not hand coded BSet.
11726 2002-03-04 Akim Demaille <akim@epita.fr>
11728 * src/closure.c (ruleset): Be a bitset.
11729 (rulesetsize): Remove.

11738 2002-02-28 Robert Anisko <robert@lrde.epita.fr>
11740 * data/bison.c++: Merge the two generated headers. Insert a copyright
11741 notice in each output file.
11743 2002-02-28 Akim Demaille <akim@epita.fr>
11745 * data/bison.c++: Copy the prologue of bison.simple to fetch
11746 useful M4 definitions, such as b4_header_guard.
11748 2002-02-25 Akim Demaille <akim@epita.fr>
11750 * src/getargs.c (version): Give the name of the authors, and use a
11751 translator friendly scheme for the bgr
11754 2002-02-25 Akim Demaille <akim@epita.fr>
11756 * src/output.c (header_output): Remove, now handled completely via
11759 2002-02-25 Akim Demaille <akim@epita.fr>
11761 * m4/m4.m4: New, from CVS Autoconf.
11762 * configure.in: Invoke it.
11763 * src/output.c (output_skeleton): Use its result instead of the
11766 2002-02-25 Akim Demaille <akim@epita.fr>
11768 * lib/tempname.c, lib/mkstemp.c, m4/mkstemp.m4: New, stolen from
11770 * configure.in: Invoke UTILS_FUNC_MKSTEMP.
11771 * src/output.c (output_skeleton): Use mkstemp to create a real
11773 Move the filling of `skeleton' and its muscle to...
11775 (output): Move the definition of the prologue muscle to...
11777 * src/system.h (DEFAULT_TMPDIR): New.
11779 2002-02-14 Paul Eggert <eggert@twinsun.com>
11781 Remove the support for C++ namespace cleanliness; it was
11782 causing more problems than it was curing, since it didn't work
11783 properly on some nonstandard C++ compilers. This can wait
11784 for a proper C++ parser.
11786 * NEWS: Document this.
11787 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
11788 of C++, as it's treated like C now.
11789 * src/bison.simple (YYSTD): Remove.
11790 (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
11791 Treat C++ just like Standard C instead of trying to support
11792 namespace cleanliness.

11796 * tests/regression.at (else): Adjust to Andreas' change.
11798 2002-02-14 Akim Demaille <akim@epita.fr>
11800 * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c.
11802 2002-02-13 Andreas Schwab <schwab@suse.de>
11804 * src/output.c (output_rule_data): Don't output NULL, it might
11805 not be defined yet.
11807 2002-02-11 Robert Anisko <robert@lrde.epita.fr>
11809 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
11810 (Copyright notice): Update.
11812 2002-02-11 Akim Demaille <akim@epita.fr>
11814 * tests/regression.at (%nonassoc and eof): Don't include
11815 nonportable headers.
11817 2002-02-08 Robert Anisko <robert@lrde.epita.fr>
11819 * data/bison.c++: Correct error recovery. Make the user able to
11820 initialize the starting location.
11822 2002-02-07 Akim Demaille <akim@epita.fr>
11824 * tests/input.at: New.
11826 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
11828 * data/bison.c++: Replace some direct m4 expansions by constants. Be
11829 more consistent when naming methods and variables. Put preprocessor
11830 directives around tables only needed for debugging.
11832 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
11834 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
11836 (yy::b4_name::parse): Use print_.
11838 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
11840 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
11842 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
11844 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
11846 (yy::b4_name::parse): Build verbose error messages, and use error_.
11848 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
11850 * data/bison.c++: Fix m4 quoting in comments.
11852 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
11854 * data/bison.c++: Adjust the parser code. Fix some muscles that were
11855 not expanded by m4.
11857 2002-02-05 Akim Demaille <akim@epita.fr>
11859 * data/bison.c++: Adjust to the M4 back end.
11860 More is certainly needed.
11862 2002-02-05 Akim Demaille <akim@epita.fr>
11864 Give a try to M4 as a back end.
11866 * lib/readpipe.c: New, from wdiff.
11867 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
11869 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
11870 specific values. Now it is m4 that performs the lookup.
11871 * src/parse-skel.y: Remove.
11872 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
11873 * src/output.c (actions_output, guards_output)
11874 (token_definitions_output): No longer keeps track of the output
11875 line number, hence remove the second argument.
11876 (guards_output): Check against the guard member of a rule, not the
11879 (output_skeleton): Don't look for the skeleton location, let m4 do
11881 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
11883 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
11884 (prepare): Given that for the time being changesyntax is not
11885 usable in M4, rename the muscles using `-' to `_'.
11886 Define `defines_flag', `output_parser_name' and `output_header_name'.
11887 * src/output.h (actions_output, guards_output)
11888 (token_definitions_output): Adjust prototypes.
11889 * src/scan-skel.l: Instead of scanning the skeletons, it now
11890 processes the output of m4: `__oline__' and `#output'.
11891 * data/bison.simple: Adjust to be used by M4(sugar).
11892 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
11894 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
11895 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
11896 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
11897 shamelessly stolen from CVS Autoconf.
11899 2002-02-05 Akim Demaille <akim@epita.fr>
11901 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
11902 * configure.in: Check for the declarations of free and malloc.
11903 * src/muscle_tab.c: Adjust.
11905 2002-02-05 Akim Demaille <akim@epita.fr>
11907 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
11908 which have no values.
11910 2002-02-05 Akim Demaille <akim@epita.fr>
11912 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
11915 2002-01-29 Paul Eggert <eggert@twinsun.com>
11917 * src/bison.simple (YYSIZE_T): Do not define merely because
11918 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
11919 On some platforms, <alloca.h> does not declare YYSTD (size_t).
11921 2002-01-27 Akim Demaille <akim@epita.fr>
11923 Fix `%nonassoc and eof'.
11925 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
11926 which were not properly copied! Replace
11927 memcpy (res->errs, src->errs, src->nerrs);
11929 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
11931 * tests/regression.at (%nonassoc and eof): Adjust to newest
11932 Autotest: `.' is not in the PATH.
11934 2002-01-27 Akim Demaille <akim@epita.fr>
11936 * tests/sets.at (AT_EXTRACT_SETS): New.
11937 (Nullable): Use it.
11940 2002-01-26 Akim Demaille <akim@epita.fr>
11942 * tests/actions.at, tests/calc.at, tests/headers.at,
11943 * tests/torture.at: Adjust to the newest Autotest which no longer
11944 forces `.' in the PATH.
11946 2002-01-25 Akim Demaille <akim@epita.fr>
11948 * tests/regression.at (%nonassoc and eof): New.
11949 Suggested by Robert Anisko.
11951 2002-01-24 Akim Demaille <akim@epita.fr>
11953 Bison dumps core when trying to complain about broken input files.
11954 Reported by Cris van Pelt.
11956 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
11957 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
11959 (Invalid inputs): Strengthen: exercise parse_percent_token.
11961 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
11963 * src/Makefile.am: Add bison.c++.
11964 * src/bison.c++: New skeleton.
11966 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
11970 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
11972 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
11974 2002-01-20 Marc Autret <marc@gnu.org>
11976 * src/files.c (compute_output_file_names): Fix
11978 2002-01-20 Marc Autret <marc@gnu.org>
11980 * tests/output.at: New test.
11981 * src/files.c (compute_base_names): Don't map extensions when
11982 the YACC flag is set, use defaults.
11983 Reported by Evgeny Stambulchik.
11985 2002-01-20 Marc Autret <marc@gnu.org>
11987 * src/system.h: Need to define __attribute__ away for non-GCC
11988 compilers as well (i.e., the vendor C compiler).
11989 Suggested by Albert Chin-A-Young.
11991 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
11993 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
11994 canonical definition.
11995 * src/system.h: Use the canonical definition for PARAMS (avoids
11996 a conflict with the macro from lib/hash.h).
11998 2002-01-11 Akim Demaille <akim@epita.fr>
12000 * configure.in: Use AC_FUNC_STRNLEN.
12001 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
12003 2002-01-09 Akim Demaille <akim@epita.fr>
12005 * src/files.c, src/files.h (output_infix): New.
12006 (tab_extension): Remove.
12007 (compute_base_names): Compute the former, drop the latter.
12008 * src/output.c (prepare): Insert the muscles `output-infix', and
12010 * src/parse-skel.y (string, string.1): New.
12011 (section.header): Use it.
12012 (section.yacc): Remove.
12013 (prefix): Remove too.
12014 * src/scan-skel.l: Adjust.
12015 * src/bison.simple, src/bison.hairy: Adjust.
12017 2002-01-09 Akim Demaille <akim@epita.fr>
12019 * configure.in (WERROR_CFLAGS): Compute it.
12020 * src/Makefile.am (CFLAGS): Pass it.
12021 * tests/atlocal.in (CFLAGS): Idem.
12022 * src/files.c: Fix a few warnings.
12023 (get_extension_index): Remove, unused.
12025 2002-01-08 Akim Demaille <akim@epita.fr>
12027 * src/getargs.c (AS_FILE_NAME): New.
12028 (getargs): Use it to convert DOSish file names.
12029 * src/files.c (base_name): Rename as full_base_name to avoid
12030 clashes with `base_name ()'.
12031 (filename_split): New.
12032 (compute_base_names): N-th rewrite, using filename_split.
12034 2002-01-08 Akim Demaille <akim@epita.fr>
12036 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
12037 New, stolen from the Fileutils 4.1.
12038 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
12039 * configure.in: Check for the presence of memrchr, and of its
12042 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
12044 * lib/hash.h (__P): Added definition for this macro.
12045 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
12046 BUILT_SOURCES, to ensure they are generated first.
12047 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
12048 %error-verbose to allow bootstrapping with bison 1.30x.
12050 2002-01-06 Akim Demaille <akim@epita.fr>
12052 * src/reader.c (parse_braces): Don't fetch the next char, the
12053 convention is to fetch on entry.
12054 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
12055 'switch' without a following semicolon.
12056 * tests/regression.at (braces parsing): New.
12058 2002-01-06 Akim Demaille <akim@epita.fr>
12060 Bison is dead wrong in its RR conflict reports.
12062 * tests/torture.at (GNU Cim Grammar): New.
12063 * src/conflicts.c (count_rr_conflicts): Fix.
12065 2002-01-06 Akim Demaille <akim@epita.fr>
12067 Creating package.m4 from configure.ac causes too many problems.
12069 * tests/Makefile.am (package.m4): Create it by hand,
12070 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
12072 2002-01-06 Akim Demaille <akim@epita.fr>
12074 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
12077 2002-01-04 Paul Eggert <eggert@twinsun.com>
12079 * doc/bison.texinfo (Debugging):
12080 Remove YYSTDERR; it's no longer defined or used.
12081 Also, s/cstdio.h/cstdio/.
12083 2002-01-03 Akim Demaille <akim@epita.fr>
12085 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
12087 2002-01-03 Akim Demaille <akim@epita.fr>
12089 * src/parse-skel.y (process_skeleton): Don't bind the parser's
12090 tracing code to --trace, wait for a better --trace option, with
12093 2002-01-03 Akim Demaille <akim@epita.fr>
12095 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
12096 The ISO C++ standard is extremely clear about it: stderr is
12097 considered a macro, not a regular symbol (see table 94 `Header
12098 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
12099 Therefore std:: does not apply to it. It still does with fprintf.
12100 Also, s/cstdio.h/cstdio/.
12102 2002-01-03 Akim Demaille <akim@epita.fr>
12104 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
12105 for non system headers.
12107 2002-01-02 Akim Demaille <akim@epita.fr>
12109 Equip the skeleton chain with location tracking, runtime trace,
12110 pure parser and scanner.
12112 * src/parse-skel.y: Request a pure parser, locations, and prefix
12114 (%union): Having several members with the same type does not help
12115 type mismatches, simplify.
12116 (YYPRINT, yyprint): New.
12117 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
12118 (skel_error): this.
12120 * src/scan-skel.l: Adjust to these changes.
12121 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
12122 (LOCATION_PRINT, skel_control_t): New.
12124 2001-12-30 Akim Demaille <akim@epita.fr>
12126 * src/parse-skel.y: Get rid of the shift/reduce conflict:
12127 replace `gb' with BLANKS.
12128 * src/scan-skel.l: Adjust.
12130 2001-12-30 Akim Demaille <akim@epita.fr>
12132 * src/system.h: We don't need nor want bcopy.
12133 Throw away MS-DOS crap: we don't need getpid.
12134 * configure.in: We don't need strndup. It was even causing
12135 problems: because Flex includes the headers *before* us,
12136 _GNU_SOURCE is not defined by config.h, and therefore strndup was
12138 * lib/xstrndup.c: New.
12139 * src/scan-skel.l: Use it.
12140 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
12141 * src/parse-skel.y: Use %directives instead of #defines.
12143 2001-12-30 Akim Demaille <akim@epita.fr>
12145 * src/skeleton.h: New.
12146 * src/output.c (output_parser, output_master_parser): Remove, dead
12148 * src/output.h (get_lines_number, actions_output, guards_output)
12149 (token_definitions_output): Prototype them.
12150 * src/parse-skel.y: Add the license notice.
12151 Include output.h and skeleton.h.
12152 (process_skeleton): Returns void, and takes a single parameter.
12153 * src/scan-skel.l: Add the license notice.
12154 Include skeleton.h.
12155 Don't use %option yylineno: it seems that then Flex imagines
12156 REJECT has been used, and therefore it won't reallocate its
12157 buffers (which makes no other sense to me than a bug). It results
12158 in warnings for `unused: yy_flex_realloc'.
12160 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
12162 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
12163 (MUSCLE_INSERT_PREFIX): ...to there.
12164 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
12165 (MUSCLE_INSERT_PREFIX): Move from here...
12167 * src/bison.hairy: Add a section directive. Put braces around muscle
12168 names. This parser skeleton is still broken, but Bison should not
12169 choke on a bad muscle 'syntax'.
12170 * src/bison.simple: Add a section directive. Put braces around muscle
12173 * src/files.h (strsuffix, stringappend): Add declarations.
12174 (tab_extension): Add declaration.
12175 (short_base_name): Add declaration.
12177 * src/files.c (strsuffix, stringappend): No longer static. These
12178 functions are used in the skeleton parser.
12179 (tab_extension): New.
12180 (compute_base_names): Use the computations done in this function
12181 to guess if the generated parsers should have '.tab' in their
12183 (short_base_name): No longer static.
12185 * src/output.c (output_skeleton): New.
12186 (output): Disable call to output_master_parser, and give a try to
12187 a new skeleton handling system.
12188 (guards_output, actions_output): No longer static.
12189 (token_definitions_output, get_lines_number): No longer static.
12191 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
12193 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
12196 * src/parse-skel.y: New file.

12201 %name-prefix is broken.
12203 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
12204 Adjust all dependencies.
12205 * tests/headers.at (export YYLTYPE): Strengthen this test: use
12208 Renaming yylval but not yylloc is not consistent. Now we do.
12210 * src/bison.simple: Prefix yylloc if used.
12211 * doc/bison.texinfo (Decl Summary): Document that.
12213 2001-12-29 Akim Demaille <akim@epita.fr>
12215 * doc/bison.texinfo: Promote `%long-directive' over
12217 Remove all references to fixed-output-files, yacc is enough.
12219 2001-12-29 Akim Demaille <akim@epita.fr>
12221 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
12222 user prologue. These are defaults.
12223 * tests/actions.at (Mid-rule actions): Make sure the user can
12224 define YYDEBUG and YYERROR_VERBOSE.
12226 2001-12-29 Akim Demaille <akim@epita.fr>
12228 * src/output.c (header_output): Don't forget to export YYLTYPE and
12230 * tests/headers.at (export YYLTYPE): New, make sure it does.
12231 * tests/regression.at (%union and --defines, Invalid CPP headers):
12233 * tests/headers.at: here.
12235 2001-12-29 Akim Demaille <akim@epita.fr>

12239 2001-12-29 Akim Demaille <akim@epita.fr>
12241 * tests/actions.at (Mid-rule actions): Output on a single line
12242 instead of several.

12246 * doc/bison.texinfo: Formatting changes.
12248 2001-12-29 Akim Demaille <akim@epita.fr>
12250 Don't store the token defs in a muscle, just be ready to output it
12251 on command. Now possible via `symbols'. Fixes a memory leak.
12253 * src/output.c (token_definitions_output): New.
12254 (output_parser, header_output): Use it.
12255 * src/reader.c (symbols_save): Remove.
12257 2001-12-29 Akim Demaille <akim@epita.fr>
12259 * src/bison.simple: Do not provide a default for YYSTYPE and
12260 YYLTYPE before the user's prologue. Otherwise it's hardly... a
12263 2001-12-29 Akim Demaille <akim@epita.fr>
12265 Mid-rule actions are simply... ignored!
12267 * src/reader.c (readgram): Be sure to attach mid-rule actions to
12268 the empty-rule associated to the dummy symbol, not to the host
12270 * tests/actions.at (Mid-rule actions): New.
12272 2001-12-29 Akim Demaille <akim@epita.fr>
12276 * src/reader.c (reader): Free grammar.
12278 2001-12-29 Akim Demaille <akim@epita.fr>
12282 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
12283 since it allocates it for each state, although only one is needed.
12284 (allocate_storage): Do it here.
12286 2001-12-29 Akim Demaille <akim@epita.fr>
12288 * src/options.h, src/options.c (create_long_option_table): Rename
12290 (long_option_table_new): this, with a clearer prototype.
12291 (percent_table): Remove, unused,
12292 * src/getargs.c (getargs): Adjust.
12294 2001-12-29 Akim Demaille <akim@epita.fr>
12296 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c

12300 2001-12-29 Akim Demaille <akim@epita.fr>
12302 * src/lalr.c (build_relations): Rename `states' as `states1'.
12303 Sorry, I don't understand exactly what it is, no better name...
12305 2001-12-29 Akim Demaille <akim@epita.fr>
12307 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
12308 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c

12324 * src/gram.c, src/gram.h (sprec, sassoc): Remove.

12336 * src/reader.c (packsymbols): Fill this table.
12338 * src/conflicts.c (resolve_sr_conflict): Adjust.
12339 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
12341 Use symbols[i]->tag instead of tags[i].
12343 2001-12-29 Akim Demaille <akim@epita.fr>
12345 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
12346 In addition, put a comment in there, to replace...
12347 * tests/regression.at (%union and C comments): Remove.
12349 2001-12-29 Akim Demaille <akim@epita.fr>
12351 * tests/regression.at (Web2c Actions): Blindly move the actual
12352 output as expected output. The contents *seem* right to me, but I
12353 can't pretend reading perfectly parser tables... Nonetheless, all
12354 the other tests pass correctly, the table look OK, even though the
12355 presence of `$axiom' is to be noted: AFAICS it is useless (but
12358 2001-12-29 Akim Demaille <akim@epita.fr>
12360 * src/reader.c (readgram): Don't add the rule 0 if there were no
12361 rules read. In other words, add it _after_ having performed
12362 grammar sanity checks.
12363 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
12365 2001-12-29 Akim Demaille <akim@epita.fr>
12367 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
12368 visible, and some states have now a different number.
12370 2001-12-29 Akim Demaille <akim@epita.fr>
12372 * src/reader.c (readgram): Bind the initial rule's lineno to that
12374 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
12375 (Solved SR Conflicts): Adjust rule 0's line number.
12377 2001-12-29 Akim Demaille <akim@epita.fr>
12379 Fix the `GAWK Grammar' failure.
12381 * src/LR0.c (final_state): Initialize to -1 so that we do compute
12382 the reductions of the first state which was mistakenly confused
12383 with the final state because precisely final_state was initialized
12385 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
12386 now noticed by Bison.
12387 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
12388 have a reduction on $default.
12390 2001-12-29 Akim Demaille <akim@epita.fr>
12392 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
12394 * src/closure.c (print_closure): Likewise.
12395 * src/derives.c (print_derives): Likewise.
12396 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
12399 2001-12-29 Akim Demaille <akim@epita.fr>
12401 * src/lalr.c (lookaheads_print): New.
12402 (lalr): Call it when --trace-flag.
12403 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
12406 2001-12-29 Akim Demaille <akim@epita.fr>
12408 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
12409 when walking through ritem, even via rule->rhs.
12410 * src/reduce.c (dump_grammar, useful_production, reduce_output)
12411 (useful_production, useless_nonterminals): Likewise.
12412 (reduce_grammar_tables): Likewise, plus update nritems.
12413 * src/nullable.c (set_nullable): Likewise.
12414 * src/lalr.c (build_relations): Likewise.
12415 * tests/sets.at (Nullable): Adjust.
12416 Fortunately, now, the $axiom is no longer nullable.
12418 2001-12-29 Akim Demaille <akim@epita.fr>
12420 * src/LR0.c (generate_states): Use nritems, not nitems, nor using

12428 2001-12-29 Akim Demaille <akim@epita.fr>
12430 * src/output.c: Comment changes.
12432 2001-12-27 Paul Eggert <eggert@twinsun.com>
12434 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
12435 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
12436 Sparc, as they were causing more porting problems than the
12437 (minor) performance improvement was worth.
12439 Also, catch up with 1.31's YYSTD.
12441 2001-12-27 Akim Demaille <akim@epita.fr>
12443 * src/output.c (output_gram): Rely on nritems, not the
12444 0-sentinel. See below.
12445 Use -1 as separator, not 0.
12446 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
12447 Rely on -1 as separator in yyrhs, instead of 0.
12448 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
12449 twice `Now at end of input', therefore there are two lines less to
12452 2001-12-27 Akim Demaille <akim@epita.fr>
12454 * tests/regression.at (Unresolved SR Conflicts):
12455 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
12458 2001-12-27 Akim Demaille <akim@epita.fr>
12460 * src/LR0.c (new_state): Recognize the final state by the fact it
12461 is reached by eoftoken.
12462 (insert_start_shifting_state, insert_eof_shifting_state)
12463 (insert_accepting_state, augment_automaton): Remove, since now
12464 these states are automatically computed from the initial state.
12465 (generate_states): Adjust.
12466 * src/print.c: When reporting a rule number to the user, substract
12467 1, so that the axiom rule is rule 0, and the first user rule is 1.
12468 * src/reduce.c: Likewise.
12469 * src/print_graph.c (print_core): For the time being, just as for
12470 the report, depend upon --trace-flags to dump the full set of
12472 * src/reader.c (readgram): Once the grammar read, insert the rule
12473 0: `$axiom: START-SYMBOL $'.
12474 * tests/set.at: Adjust: rule 0 is now displayed, and since the
12475 number of the states has changed (the final state is no longer
12476 necessarily the last), catch up.
12478 2001-12-27 Akim Demaille <akim@epita.fr>
12480 Try to make the use of the eoftoken valid. Given that its value
12481 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
12482 is used instead of > 0 where appropriate, (ii), depend upon nritems
12483 instead of the 0-sentinel.
12485 * src/gram.h, src/gram.c (nritems): New.
12486 Expected to be duplication of nitems, but for the time being...
12487 * src/reader.c (packgram): Assert nritems and nitems are equal.
12488 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
12489 * src/closure.c (print_closure, print_fderives): Likewise.

12494 2001-12-27 Akim Demaille <akim@epita.fr>
12496 * src/main.c (main): If there are complains after grammar
12497 reductions, then output the report anyway if requested, then die.
12498 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
12499 * src/reader.c (eoftoken): New.
12500 (parse_token_decl): If the token being defined has value `0', it
12502 (packsymbols): No longer hack `tags' to insert `$' by hand.
12503 Be sure to preserve the value of the eoftoken.
12504 (reader): Make sure eoftoken is defined.
12505 Initialize nsyms to 0: now eoftoken is created just like the others.
12506 * src/print.c (print_grammar): Don't special case the eof token.
12507 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
12508 lie anyway, albeit pleasant.
12509 * tests/calc.at: Exercise error messages with eoftoken.
12510 Change the grammar so that empty input is invalid.
12511 Adjust expectations.
12512 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
12514 2001-12-27 Akim Demaille <akim@epita.fr>
12516 * configure.in: Check the protos of strchr ans strspn.
12517 Replace strchr if needed.
12518 * src/system.h: Provide the protos of strchr, strspn and memchr if
12520 * lib/strchr.c: New.
12521 * src/reader.c (symbols_save): Use strchr.
12523 2001-12-27 Akim Demaille <akim@epita.fr>
12525 * src/print.c, src/print_graph.c (escape): New.
12526 Use it to quote the TAGS outputs.
12527 * src/print_graph.c (print_state): Now errors are in red, and
12528 reductions in green.
12529 Prefer high to wide: output the state number on a line of its own.
12531 2001-12-27 Akim Demaille <akim@epita.fr>
12533 * src/state.h, src/state.c (reductions_new): New.
12534 * src/LR0.c (set_state_table): Let all the states have a
12535 `reductions', even if reduced to 0.
12536 (save_reductions): Adjust.

12554 2001-12-27 Akim Demaille <akim@epita.fr>
12556 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
12557 * src/print.c: here.
12558 (lookaheadset, shiftset): New, used as additional storage by
12560 (print_results): Adjust.
12561 (print_shifts, print_gotos, print_errs): New, extracted from...
12562 (print_actions): here.
12563 * src/print_graph.c (print_actions): Remove dead code.
12565 2001-12-27 Akim Demaille <akim@epita.fr>
12567 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
12570 2001-12-27 Akim Demaille <akim@epita.fr>
12572 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
12573 (build_relations): Adjust.
12575 2001-12-27 Akim Demaille <akim@epita.fr>
12577 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
12580 2001-12-27 Akim Demaille <akim@epita.fr>
12582 * src/reader.c (packgram): Catch nitems overflows.
12584 2001-12-27 Akim Demaille <akim@epita.fr>
12586 * src/files.c, src/files.h (guard_obstack): Remove.
12587 * src/output.c (output): Adjust.
12588 * src/reader.c (parse_braces): New, factoring...
12589 (copy_action, copy_guard): these two which are renamed as...
12590 (parse_action, parse_guard): these.
12591 As a voluntary consequence, using braces around guards is now
12594 2001-12-27 Akim Demaille <akim@epita.fr>
12596 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
12597 * src/reader.c (symbol_list): `guard' and `guard_line' are new
12599 (symbol_list_new): Adjust.
12600 (copy_action): action_line is the first line, not the last.
12601 (copy_guard): Just as for actions, store the `action' only, not
12602 the switch/case/break flesh.
12603 Don't parse the user action that might follow the guard, let...
12604 (readgram): do it, i.e., now, there can be an action after a
12606 In other words the guard is just explicitly optional.
12607 (packgram): Adjust.
12608 * src/output.c (guards_output): New.
12609 (output_parser): Call it when needed.
12610 (output): Also free the guard and attrs obstacks.
12611 * src/files.c, src/files.h (obstack_save): Remove.
12612 (output_files): Remove.
12613 As a result, if one needs the former `.act' file, using an
12614 appropriate skeleton which requires actions and guards is now
12616 * src/main.c (main): Adjust.
12617 * tests/semantic.at: New.
12618 * tests/regression.at: Use `input.y' as input file name.
12619 Avoid 8+3 problems by requiring input.c when the test needs the

12624 * src/reader.c (symbol_list_new): Be sure to initialize all the
12627 2001-12-27 Akim Demaille <akim@epita.fr>
12629 All the hacks using a final pseudo state are now useless.
12631 * src/LR0.c (set_state_table): state_table holds exactly nstates.
12632 * src/lalr.c (nLA): New.
12633 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
12634 instead of lookaheadsp from the pseudo state (nstate + 1).
12636 2001-12-27 Akim Demaille <akim@epita.fr>
12638 * src/output.c (action_row, token_actions): Use a state_t instead
12639 of a integer, and nlookaheads instead of the following state's

12646 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
12647 (conflicts_print, print_reductions): Use a state_t instead of an
12648 integer when referring to a state.
12649 As much as possible, depend upon nlookaheads, instead of the
12650 `lookaheadsp' member of the following state (since lookaheads of
12651 successive states are successive, the difference between state n + 1
12652 and n served as the number of lookaheads for state n).
12653 * src/lalr.c (add_lookback_edge): Likewise.
12654 * src/print.c (print_core, print_actions, print_state)
12655 (print_results): Likewise.

12665 Add plenty of `static'.
12667 2001-12-27 Akim Demaille <akim@epita.fr>
12669 * src/output.c (prepare): Drop the muscle `ntbase' which
12670 duplicates ntokens.
12671 * src/bison.simple: Formatting/comment changes.
12672 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
12673 is an undocumented synonym.
12675 2001-12-22 Akim Demaille <akim@epita.fr>
12677 * src/output.c (output_table_data): Change the prototype to use
12678 `int' for array ranges: some invocations do pass an int, not a
12680 Reported by Wayne Green.
12682 2001-12-22 Akim Demaille <akim@epita.fr>
12684 Some actions of web2c.y are improperly triggered.
12685 Reported by Mike Castle.
12687 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
12688 * tests/regression.at (Web2c): Rename as...
12689 (Web2c Report): this.
12690 (Web2c Actions): New.
12692 2001-12-22 Akim Demaille <akim@epita.fr>
12694 Reductions in web2c.y are improperly reported.

12697 * src/conflicts.c (print_reductions): Fix.
12698 * tests/regression.at (Web2c): New.
12700 2001-12-18 Akim Demaille <akim@epita.fr>
12702 Some host fail on `assert (!"foo")', which expands to
12703 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
12704 Reported by Nelson Beebee.
12706 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
12707 `#define it_succeeded 0' and `assert (it_succeeded)'.
12709 2001-12-17 Marc Autret <autret_m@epita.fr>
12711 * src/bison.simple: Don't hard code the skeleton line and filename.
12712 * src/output.c (output_parser): Rename 'line' as 'output_line'.
12713 New line counter 'skeleton_line' (skeleton-line muscle).
12715 2001-12-17 Paul Eggert <eggert@twinsun.com>
12717 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
12718 YYDEBUG must be defined to a nonzero value.
12720 * src/bison.simple (yytname): Do not assume that the user defines
12721 YYDEBUG to a properly parenthesized expression.
12723 2001-12-17 Akim Demaille <akim@epita.fr>
12725 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
12726 nlookaheads is a new member.
12728 * src/lalr.h (nlookaheads): Remove this orphan declaration.
12729 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
12732 2001-12-17 Akim Demaille <akim@epita.fr>
12734 * src/files.h, src/files.c (open_files, close_files): Remove.
12735 * src/main.c (main): Don't open/close files, nor invoke lex_free,
12737 * src/reader.c (reader): Do it.
12739 2001-12-17 Akim Demaille <akim@epita.fr>
12741 * src/conflicts.c (print_reductions): Formatting changes.
12743 2001-12-17 Akim Demaille <akim@epita.fr>
12745 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
12746 (flush_reduce): New.
12747 (resolve_sr_conflict): Adjust.
12749 2001-12-17 Akim Demaille <akim@epita.fr>
12751 * src/output.c (output_obstack): Be static and rename as...
12752 (format_obstack): this, to avoid any confusion with files.c's
12754 * src/reader.h (muscle_obstack): Move to...
12755 * src/output.h: here, since it's defined in output.c.
12757 2001-12-17 Akim Demaille <akim@epita.fr>
12759 * src/output.c (action_row, save_column, default_goto)
12760 (sort_actions, matching_state, pack_vector): Better variable
12763 2001-12-17 Akim Demaille <akim@epita.fr>
12765 * src/output.c: Various formatting changes.
12767 2001-12-17 Akim Demaille <akim@epita.fr>
12769 * src/files.c (output_files): Free the output_obstack.
12770 * src/main.c (main): Call print and print_graph conditionally.
12771 * src/print.c (print): Work unconditionally.
12772 * src/print_graph.c (print_graph): Work unconditionally.
12773 * src/conflicts.c (log_resolution): Output only if verbose_flag.
12775 2001-12-16 Marc Autret <autret_m@epita.fr>
12777 * src/output.c (actions_output): Fix. When we use %no-lines,
12778 there is one less line per action.
12780 2001-12-16 Marc Autret <autret_m@epita.fr>
12782 * src/bison.simple: Remove a useless #line directive.
12783 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
12784 * src/output.c (get_lines_number): New.
12785 (output_parser): Adjust, now takes care about the lines of a
12787 Fix line numbering.
12788 (actions_output): Computes the number of lines taken by actions.
12789 (output_master_parser): Insert new skeleton which is the name of
12790 the output parser file name.
12792 2001-12-15 Marc Autret <autret_m@epita.fr>
12794 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
12796 2001-12-15 Marc Autret <autret_m@epita.fr>
12798 * src/output.c (output_gram): Keep track of the hairy one.
12800 2001-12-15 Akim Demaille <akim@epita.fr>
12802 Make `make distcheck' work.
12804 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
12805 system.h which uses libgettext.h.
12807 2001-12-15 Akim Demaille <akim@epita.fr>
12809 * src/nullable.c (set_nullable): Useless rules must be skipped,
12810 otherwise, since we range over their symbols, we might look at a
12811 nonterminal which no longer ``exists'', i.e., it is not counted in
12812 `nvars', hence we overflow our arrays.
12814 2001-12-15 Akim Demaille <akim@epita.fr>
12816 The header can also be produced directly, without any obstack!
12819 * src/files.c, src/files.h (defines_obstack): Remove.
12820 (compute_header_macro): Global.
12821 (defines_obstack_save): Remove.
12822 * src/reader.c (parse_union_decl): No longer output to
12823 defines_obstack: its content can be found in the `stype' muscle
12825 (output_token_translations): Merge into...
12826 (symbols_output): this.
12828 (symbols_save): this.
12830 * src/output.c (header_output): New.
12833 2001-12-15 Akim Demaille <akim@epita.fr>
12835 * src/reader.c (parse_union_decl): Instead of handling two obstack
12836 simultaneously, use one to define the `stype' muscle, and use the
12837 value of the latter to fill defines_obstack.
12838 (copy_comment): Remove.
12839 (copy_comment2): Work for a single obstack.
12841 (copy_comment): this.
12843 2001-12-15 Akim Demaille <akim@epita.fr>
12845 * src/lex.c, src/lex.h (xgetc): No longer static.
12846 * src/reader.c (parse_union_decl): Revamp.
12848 2001-12-15 Akim Demaille <akim@epita.fr>
12850 Still making progress in separating Bison into (i) input, (ii)
12851 process, (iii) output: now we can directly output the parser file
12852 without using table_obstack at all.
12854 * src/files.c, src/files.h (table_obstack): Bye bye.
12855 (parser_file_name): New.
12856 * src/files.c (compute_output_file_names): Compute it.
12857 * src/output.c (actions_output, output_parser)
12858 (output_master_parser): To a file instead of an obstack.
12860 2001-12-15 Akim Demaille <akim@epita.fr>
12862 Attach actions to rules, instead of pre-outputting them to
12865 * src/gram.h (rule_t): action and action_line are new members.
12866 * src/reader.c (symbol_list): Likewise.
12867 (copy_action): Save the actions within the rule.
12868 (packgram): Save them in rule_table.
12869 * src/output.c (actions_output): New.
12870 (output_parser): Use it on `%%actions'.
12871 (output_rule_data): Don't free rule_table.
12873 (prepare): Don't save the `action' muscle.
12874 * src/bison.simple: s/%%action/%%actions/.
12876 2001-12-15 Akim Demaille <akim@epita.fr>
12878 * src/reader.c (copy_action): When --yacc, don't append a `;'
12879 to the user action: let it fail if lacking.
12880 Suggested by Arnold Robbins and Tom Tromey.
12882 2001-12-14 Akim Demaille <akim@epita.fr>
12884 * src/lex.c (literalchar): Simply return the char you decoded, non
12885 longer mess around with obstacks and int pointers.
12886 Adjust all callers.
12888 2001-12-14 Akim Demaille <akim@epita.fr>
12890 * src/lex.c (literalchar): Don't escape the special characters,
12891 just decode them, and keep them as char (before, eol was output as
12892 the 2 char string `\n' etc.).
12893 * src/output.c (output_rule_data): Use quotearg to output the
12896 2001-12-13 Paul Eggert <eggert@twinsun.com>
12898 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
12899 Do not infringe on the global user namespace when using C++.
12900 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
12901 All uses of `fprintf' and `stderr' changed.
12903 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
12905 2001-12-13 Akim Demaille <akim@epita.fr>
12907 The computation of nullable is broken: it doesn't handle empty
12910 * tests/torture.at (GNU AWK Grammar): New.
12911 * tests/sets.at (Nullable): New.
12912 * src/nullable.c (set_nullable): Instead of blindly looping over
12913 `ritems', loop over the rules, and then over their rhs's.
12915 Work around Autotest bugs.
12917 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
12918 frame, because Autotest understand lines starting with a `+' as
12919 traces from the shell. Then, they are not processed properly.
12920 Admittedly an Autotest bug, but we don't have time to wait for
12921 Autotest to catch up.
12922 * tests/regression.at (Broken Closure): Adjust to the new table
12925 * tests/sets.at: here.
12927 2001-12-13 Akim Demaille <akim@epita.fr>
12929 * src/closure.c (closure): Use nrules instead of playing tricks
12930 with BITS_PER_WORD.
12932 2001-12-13 Akim Demaille <akim@epita.fr>
12934 * src/print.c (print_actions): Output the handling of `$' as the
12935 traces do: shifting the token EOF. Before EOF was treated as a
12937 * tests/regression.at: Adjust some tests.
12938 * src/print_graph.c (print_core): Complete the set of items via
12939 closure. The next-to-final and final states are still unsatisfying,
12940 but that's to be addressed elsewhere.
12941 No longer output the rule numbers, but do output the state number.
12942 A single loop for the shifts + gotos is enough, but picked a
12943 distinct color for each.
12944 (print_graph): Initialize and finalize closure.
12946 2001-12-13 Akim Demaille <akim@epita.fr>
12948 * src/reader.c (readgram): Remove dead code, an strip useless
12950 (get_type): Remove, unused.
12952 2001-12-12 Akim Demaille <akim@epita.fr>
12954 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
12955 on that of lib/error.c.
12957 2001-12-12 Akim Demaille <akim@epita.fr>
12959 Some hosts don't like `/' in includes.
12961 * src/system.h: Include libgettext.h without qualifying the path.
12962 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
12965 2001-12-11 Marc Autret <autret_m@epita.fr>
12967 * src/output.c (output_parser): Remove useless muscle.
12969 2001-12-11 Marc Autret <autret_m@epita.fr>
12971 * src/bison.simple: Remove #line just before %%epilogue. It
12972 is now handled in ...
12973 * src/reader.c (read_additionnal_code): Add the output of a
12974 #line for the epilogue.
12976 2001-12-10 Marc Autret <autret_m@epita.fr>
12978 * src/reader.c (copy_definition): Re-use CPP-outed code which
12979 replace precedent remove.
12980 * src/bison.simple: Remove #line before %%prologue because
12981 %%input-line is wrong at this time.
12983 2001-12-10 Marc Autret <autret_m@epita.fr>
12985 * src/reader.c (symbols_output): Clean up.
12986 * src/output.c (output_gram, output): Clean up.
12988 2001-12-10 Akim Demaille <akim@epita.fr>
12990 * src/lalr.c (initialize_lookaheads): New. Extracted from...
12991 * src/LR0.c (set_state_table): here.
12992 * src/lalr.c (lalr): Call it.
12994 2001-12-10 Akim Demaille <akim@epita.fr>
12996 * src/state.h (shifts): Remove the `number' member: shifts are
12997 attached to state, hence no longer need to be labelled with a
13000 2001-12-10 Akim Demaille <akim@epita.fr>
13002 Now that states have a complete set of members, the linked list of
13003 shifts is useless: just fill directly the state's shifts member.
13005 * src/state.h (shifts): Remove the `next' member.
13006 * src/LR0.c (first_state, last_state): Remove.
13007 Adjust the callers.
13008 (augment_automaton): Don't look for the shifts that must be added
13009 a shift on EOF: it is those of the state we looked for! But now,
13010 since shifts are attached, it is no longer needed to looking
13011 merely by its id: its number.
13013 2001-12-10 Akim Demaille <akim@epita.fr>
13015 * src/LR0.c (augment_automaton): Better variable locality.
13016 Remove an impossible branch: if there is a state corresponding to
13017 the start symbol being shifted, then there is shift for the start
13018 symbol from the initial state.
13020 2001-12-10 Akim Demaille <akim@epita.fr>
13022 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
13023 only when appropriate: when insert_start_shifting_state' is not
13025 * tests/regression.at (Rule Line Numbers): Adjust.
13027 2001-12-10 Akim Demaille <akim@epita.fr>
13029 * src/LR0.c (augment_automaton): Now that all states have shifts,
13030 merge the two cases addition shifts to the initial state.
13032 2001-12-10 Akim Demaille <akim@epita.fr>
13034 * src/lalr.c (set_state_table): Move to...
13036 * src/lalr.c (lalr): Don't call it...
13037 * src/LR0.c (generate_states): do it.
13038 * src/LR0.h (first_state): Remove, only the table is used.
13040 2001-12-10 Akim Demaille <akim@epita.fr>
13042 * src/LR0.h (first_shift, first_reduction): Remove.
13043 * src/lalr.c: Don't use first_shift: find shifts through the
13046 2001-12-10 Akim Demaille <akim@epita.fr>
13048 * src/LR0.c: Attach shifts to states as soon as they are
13050 * src/lalr.c (set_state_table): Instead of assigning shifts to
13051 state, just assert that the mapping was properly done.
13053 2001-12-10 Akim Demaille <akim@epita.fr>
13055 * src/LR0.c (insert_start_shift): Rename as...
13056 (insert_start_shifting_state): this.
13057 (insert_eof_shifting_state, insert_accepting_state): New.
13058 (augment_automaton): Adjust.
13059 Better locality of the variables.
13060 When looking if the start_symbol is shifted from the initial
13061 state, using `while (... symbol != start_symbol ...)' sounds
13062 better than `while (... symbol < start_symbol ...)': If fail
13063 to see how the order between symbols could be relevant!
13065 2001-12-10 Akim Demaille <akim@epita.fr>
13067 * src/getargs.h: Don't declare `spec_name_prefix' and
13068 `spec_file_prefix', declared by src/files.h.
13069 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
13070 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
13071 * src/output.c (prepare): Adjust.
13072 * src/reader.c (symbols_output): Likewise.
13073 * src/vmsgetargs.c: Vaguely adjust, but who cares?
13075 2001-12-10 Akim Demaille <akim@epita.fr>
13077 * src/muscle_tab.c (muscle_init): NULL is a better default than
13080 2001-12-10 Akim Demaille <akim@epita.fr>
13082 * src/reader.c (reader): Calling symbols_output once is enough.
13084 2001-12-10 Akim Demaille <akim@epita.fr>
13086 Now that states have a complete set of members, the linked list of
13087 reductions is useless: just fill directly the state's reductions
13090 * src/state.h (struct reductions): Remove member `number' and
13092 * src/LR0.c (first_reduction, last_reduction): Remove.
13093 (save_reductions): Don't link the new reductions, store them in
13095 * src/lalr.c (set_state_table): No need to attach reductions to
13096 states, it's already done.
13097 * src/output.c (output_actions): No longer free the shifts, then
13098 the reductions, then the states: free all the states and their
13101 2001-12-10 Akim Demaille <akim@epita.fr>
13103 * src/options.c (OPTN, DRTV, BOTH): New.
13104 (option_table): Use them.
13106 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
13107 the job of system.h.
13108 * src/options.c: Don't include stdio.h and xalloc.h for the same
13111 2001-12-10 Akim Demaille <akim@epita.fr>
13113 * src/output.c (output, prepare): Make sure the values of the
13114 muscles `action' and `prologue' are 0-terminated.
13116 2001-12-10 Akim Demaille <akim@epita.fr>
13118 Clean up GCC warnings.
13120 * src/reader.c (copy_action): `buf' is not used.
13121 (parse_skel_decl): Be static.
13122 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
13123 * src/options.h (create_long_option_table): Have a real prototype.
13124 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
13125 (hash_delete_at): Return const void *.
13126 Adjust casts to preserve the const.
13128 2001-12-10 Akim Demaille <akim@epita.fr>
13130 * configure.in: Require 2.52g.
13131 M4 is not needed, but AUTOM4TE is.
13132 * m4/m4.m4: Remove.
13133 * tests/Makefile.am: Adjust.
13135 2001-12-10 Akim Demaille <akim@epita.fr>
13137 One structure for states is enough, even though theoretically
13138 there are LR(0) states and LALR(1) states.
13140 * src/lalr.h (state_t): Remove.
13141 (state_table): Be state_t **, not state_t *.
13142 * src/state.h (core, CORE_ALLOC): Rename as...
13143 (state_t, STATE_ALLOC): this.
13144 Add the LALR(1) members: shifts, reductions, errs.
13145 * src/LR0.c (state_table): Rename as...
13146 (state_hash): this, to avoid name clashes with the global
13148 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
13149 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
13151 2001-12-10 Akim Demaille <akim@epita.fr>
13153 Bison dumps core on bash.y.
13154 Reported by Pascal Bart.
13156 * src/warshall.c (bitmatrix_print): New.
13158 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
13159 j must be the outer loop.
13160 * tests/regression.at (Broken Closure): New.
13162 2001-12-05 Akim Demaille <akim@epita.fr>
13164 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
13166 Reported by Peter Hamorsky.
13168 2001-12-05 Akim Demaille <akim@epita.fr>
13170 * src/conflicts.c (err_table): Remove.
13171 (resolve_sr_conflict): Adjust.
13172 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
13174 (state_t.reductions, state_t.shifts): this.
13176 2001-12-05 Akim Demaille <akim@epita.fr>
13178 * src/reduce.c (reduce_grammar_tables): No longer disable the
13179 removal of useless rules via CPP but via `if (0)', so that the
13180 compiler still check the code is valid.
13181 For instance, it should have noticed `rline' no longer exists: use
13182 the `line' member of rule_t.
13183 * src/gram.c (dummy, rline): Remove, unused.
13185 2001-12-05 Akim Demaille <akim@epita.fr>
13187 * src/output.c (pack_vector): Use assert, not berror.
13188 * src/main.c (berror): Remove, unused.
13190 2001-12-05 Akim Demaille <akim@epita.fr>
13192 New experimental feature: if --verbose --trace output all the
13193 items of a state, not only its kernel.
13195 * src/print.c (print_core): If `trace_flag', then invoke closure
13196 before outputting the items of the state (print_core is no longer
13197 a correct name them).
13198 (print_results): Invoke new_closure/free_closure if needed.
13200 2001-12-05 Akim Demaille <akim@epita.fr>
13202 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
13203 * src/closure.c, src/closure.h (itemsetsize): Rename as...
13204 (nitemset): for consistency with the rest of the project.
13206 2001-12-05 Akim Demaille <akim@epita.fr>
13208 * src/closure.c (print_closure): Improve.
13209 (closure): Use it for printing input and output.
13211 2001-12-05 Akim Demaille <akim@epita.fr>
13213 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
13214 indexed by nonterminals.
13216 2001-12-05 Akim Demaille <akim@epita.fr>
13218 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of

13237 using the good o' techniques: arrays not pointers, variable
13238 locality, BITISSET, RESETBIT etc.
13240 2001-12-05 Akim Demaille <akim@epita.fr>
13242 Pessimize the code to simplify it: from now on, all the states
13243 have a valid SHIFTS, which NSHIFTS is possibly 0.
13245 * src/LR0.c (shifts_new): Be global and move to..
13246 * src/state.c, src/state.h: here.
13247 * src/conflicts, src/lalr.c, src/output.c, src/print.c,

13253 * src/conflicts.c: Use it.
13254 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
13255 incorrectly ``simplified''.

13259 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
13260 using the good o' techniques: arrays not pointers, variable
13261 locality, BITISSET, RESETBIT etc.
13263 2001-12-05 Akim Demaille <akim@epita.fr>
13265 * src/state.h (SHIFT_SYMBOL): New.

13295 2001-12-05 Akim Demaille <akim@epita.fr>
13297 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.

13313 * src/lalr.c (maxrhs): Move to...
13314 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
13315 * src/lalr.c (build_relations): Adjust.
13317 2001-12-05 Akim Demaille <akim@epita.fr>
13319 * src/lalr.c (transpose): Free the memory allocated to the
13320 argument, as it is replaced by the results by the unique caller.
13321 (build_relations): Merely invoke transpose: it handles the memory
13323 Improve variable locality.
13324 Avoid variables used as mere abbreviations.
13325 (compute_lookaheads): Use arrays instead of pointers.
13327 2001-12-05 Akim Demaille <akim@epita.fr>
13329 * src/lalr.c (initialize_F): Improve variable locality.
13330 Avoid variables used as mere abbreviations.

13343 2001-12-05 Akim Demaille <akim@epita.fr>
13345 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
13346 the handling of squeue.
13347 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
13349 2001-12-05 Akim Demaille <akim@epita.fr>
13351 Because useless nonterminals are now kept alive (instead of being
13352 `destroyed'), we now sometimes examine them, and store information
13353 related to them. Hence we need to know their number, and adjust
13354 memory allocations.
13356 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
13358 * src/LR0.c (allocate_itemsets): The memory allocated to
13359 `symbol_count' was used for two different purpose: once to count
13360 the number of occurrences of each symbol, and later reassigned to
13361 `shift_symbol', containing the symbol that can be shifted from a
13363 Deobfuscate, i.e., allocate, use and free `symbol_count' here
13365 (new_itemsets): Allocate `shift_symbol' here.
13366 (allocate_itemsets): symbol_count includes useless nonterminals.
13367 Make room for them.
13368 (free_storage): Use `free', not `XFREE', for pointers that cannot
13371 2001-12-05 Akim Demaille <akim@epita.fr>
13373 * src/nullable.c (set_nullable): Deobfuscate the handling of
13375 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
13377 2001-12-05 Akim Demaille <akim@epita.fr>
13379 * src/gram.c, src/gram.h (ritem_print): New.
13380 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
13381 (This useless function was defined only to work around VMS linkers
13382 that can't handle compilation units with variables only).
13383 * src/reduce.c (dump_grammar): Use it to trace the construction of
13386 2001-12-04 Paul Eggert <eggert@twinsun.com>
13388 * src/bison.simple (union yyalloc): Change member names
13389 to be the same as the stack names.
13390 (yyparse): yyptr is now union yyalloc *, not char *.
13391 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
13392 and may generate better code on some machines.
13393 (yystpcpy): Use prototype if __STDC__ is defined, not just
13394 if __cplusplus is defined.
13396 2001-11-30 Akim Demaille <akim@epita.fr>
13398 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
13399 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
13400 Gettext doesn't compile cleanly, and dies with -Werror.
13401 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
13402 Include WARNING_CFLAGS here.
13403 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
13404 before being defined.
13406 2001-11-27 Paul Eggert <eggert@twinsun.com>
13408 * lib/quotearg.h (quotearg_n, quotearg_n_style):
13409 First arg is int, not unsigned.

13411 (SIZE_MAX, UINT_MAX): New macros.
13412 (quotearg_n_options): Abort if N is negative.
13413 Avoid overflow check on hosts where size_t is 64 bits and int
13414 is 32 bits, as overflow is impossible there.
13415 Fix off-by-one typo that caused unnecessary reallocation.
13417 2001-11-29 Paul Eggert <eggert@twinsun.com>
13419 Name space cleanup in generated parser.
13421 * doc/bison.texinfo (Bison Parser): Discuss system headers
13422 and their effect on the user name space.
13424 * src/bison.simple:
13425 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
13426 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
13427 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
13429 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
13430 on user names when possible.
13432 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
13433 Simplify test for whather <alloca.h> exists.
13435 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
13437 (<stdio.h>): Include if YYDEBUG.
13439 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
13440 ! defined (yyoverflow) && ! defined (yymemcpy).
13442 (yymemcpy, yyparse): Rename local variables as needed so that
13443 they all begin with 'yy'.
13445 (yystrlen, yystpcpy): New functions.
13447 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
13450 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
13451 instead of relying on string.h functions. Use YYSTACK_ALLOC
13452 and YYSTACK_FREE instead of malloc and free.
13454 2001-11-30 Akim Demaille <akim@epita.fr>
13456 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
13457 before their first uses.

13467 if body instead of `;' to pacify GCC's warnings.
13469 2001-11-30 Akim Demaille <akim@epita.fr>
13471 Instead of mapping the LHS of unused rules to -1, keep the LHS
13472 valid, but flag the rules as invalid.
13474 * src/gram.h (rule_t): `useful' is a new member.
13475 * src/print.c (print_grammar): Adjust.
13476 * src/derives.c (set_derives): Likewise.
13477 * src/reader.c (packgram, reduce_output): Likewise.
13478 * src/reduce.c (reduce_grammar_tables): Likewise.
13479 * tests/reduce.at (Underivable Rules, Useless Rules): New.
13481 2001-11-30 Akim Demaille <akim@epita.fr>

13492 (reduce_output): Adjust.
13493 * tests/reduce.at (Useless Nonterminals): Adjust.
13495 2001-11-30 Akim Demaille <akim@epita.fr>

13505 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
13506 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
13508 (union yyalloc): New type.
13509 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
13510 an arbitrary restriction on hosts where size_t is wider than int.
13512 (yyparse): Don't dump core if alloca or malloc fails; instead, report
13513 a parser stack overflow. Allocate just one block of memory for all
13514 three stacks, instead of allocating three blocks; this typically is
13515 faster and reduces fragmentation.
13517 Do not limit the number of items in the stack to a value that fits
13518 in 'int', as this is an arbitrary limit on hosts with 64-bit
13519 size_t and 32-bit int.
13521 2001-11-29 Marc Autret <autret_m@epita.fr>
13523 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
13524 of defining YYERROR_VERBOSE.
13525 [AT_DATA]: $4 is now out of C declarations in the prologue.
13527 2001-11-28 Marc Autret <autret_m@epita.fr>

13574 2001-11-28 Akim Demaille <akim@epita.fr>
13576 * src/closure.c (closure): Instead of looping over word in array
13577 then bits in words, loop over bits in array.
13579 2001-11-28 Akim Demaille <akim@epita.fr>
13581 * src/closure.c (closure): No longer optimize the special case
13582 where all the bits of `ruleset[r]' are set to 0, to make the code
13585 2001-11-28 Akim Demaille <akim@epita.fr>
13587 * src/closure.c (closure): `r' and `c' are new variables, used to

13592 * src/reduce.c (reduce_print): Use ngettext.

13601 * tests/reduce.at (Useless Terminals, Useless Nonterminals): New.
13602 * src/reduce.c (reduce_grammar_tables): Do not free useless tags,

13606 2001-11-27 Paul Eggert <eggert@twinsun.com>
13608 * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to
13609 use alloca when we didn't want to, and vice versa.

13693 there are no reduce/reduce conflicts, and as many shift/reduce
13694 conflicts as expected.
13695 * tests/regression.at (%expect right): Adjust.
13697 2001-11-23 Akim Demaille <akim@epita.fr>

15288 2001-07-14 Akim Demaille <akim@epita.fr>
15291 * configure.in: Require Autoconf 2.50.

15324 * src/conflicts.c (conflict_report): Be sure not to append to res
15325 between two calls, which could happen if both first sprintf were
15326 skipped, but not the first cp += strlen.
15328 2001-02-08 Akim Demaille <akim@epita.fr>
15330 * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
15331 New, from fileutils 4.0.37.
15332 * configure.in: Require Autoconf 2.49c. I took some time before
15333 making this decision. This is the only way out for portability
15334 issues in Bison, it would mean way too much duplicate effort to
15335 import in Bison features implemented in 2.49c since 2.13.
15336 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
15338 2001-02-02 Akim Demaille <akim@epita.fr>

15355 * src/lex.h: Rename all the tokens:
15356 s/\bENDFILE\b/tok_eof/g;
15357 s/\bIDENTIFIER\b/tok_identifier/g;
15359 Let them be enums, not #define, to ease debugging.

15377 * src/reader.c (read_declarations): Adjust.
15378 * src/files.c (open_files): Don't call `compute_base_names', don't

15382 * src/output.c (output_headers): Document the fact that this patch
15383 introduces a guaranteed SEGV for semantic parsers.
15384 * doc/bison.texinfo: Document them.
15385 * tests/suite.at: Exercise these %options.
15387 2000-12-20 Akim Demaille <akim@epita.fr>

15399 2000-12-20 Akim Demaille <akim@epita.fr>
15401 * src/files.c (open_files): Fix the computation of short_base_name
15402 in the case of `-o foo.tab.c'.

15410 2000-12-20 Akim Demaille <akim@epita.fr>
15412 * src/files.c (open_files): Actually the `.output' file is based

15452 (obstack_grow_string): this.
15453 * src/output.c (output_parser): Recognize `%% actions' instead of
15455 * src/bison.s1: s/$/%% actions/.
15456 * src/bison.hairy: Likewise.
15458 2000-12-19 Akim Demaille <akim@epita.fr>
15460 * src/output.c (output_parser): Compute the `#line' lines when
15462 * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.

15487 * src/files.c (open_files): Yipee! We no longer need all the code

15492 * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

15519 * lib/obstack.h: Formatting changes.
15520 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
15521 prevents type checking.
15522 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't

15526 * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

15545 Use them to declare the variables which are global or local to
15548 2000-11-17 Akim Demaille <akim@epita.fr>
15550 * acconfig.h: Remove, no longer used.
15552 2000-11-07 Akim Demaille <akim@epita.fr>
15554 * src: s/Copyright (C)/Copyright/g.
15556 2000-11-07 Akim Demaille <akim@epita.fr>
15558 * src/reader.c (reader): #define YYLSP_NEEDED to 1 instead of just
15560 * src/bison.s1: s/#ifdef YYLSP_NEEDED/#if YYLSP_NEEDED/.

15576 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
15577 `const' their input argument (`data' or `address').
15578 Adjust the corresponding macros to include `const' in casts.
15580 2000-11-03 Akim Demaille <akim@epita.fr>
15582 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.
15583 s/PFILE1/BISON_HAIRY/.
15584 Adjust dependencies.
15586 2000-11-03 Akim Demaille <akim@epita.fr>
15588 For some reason, this was not applied.
15590 * src/files.c [VMS]: No longer include `ssdef.h', no longer define

15593 2000-11-03 Akim Demaille <akim@epita.fr>
15595 * src/files.c (skeleton_find): New function, eved out of...

15600 Don't use `atexit'.
15602 * src/files.c (obstack_save): New function.
15603 (done): Rename as...
15604 (output_files): this.
15605 Use `obstack_save'.
15606 * src/main.c (main): Don't use `atexit' to register `done', since
15607 it no longer has to remove tmp files, just call `output_files'
15608 when there are no errors.
15610 2000-11-02 Akim Demaille <akim@epita.fr>
15612 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
15613 `unlink': it's no longer used.
15614 * src/files.h: Formatting changes.
15616 2000-11-02 Akim Demaille <akim@epita.fr>
15618 Remove the last uses of mktemp and unlink/delete.
15620 * src/files.c (fdefines, ftable): Removed.
15621 (defines_ostack, table_obstack): New.
15622 Adjust dependencies of the former into uses of the latter.
15623 * src/output.c (output_short_or_char_table, output_short_table):

15680 * src/reader.c (copy_comment2): Expect the input stream to be on
15681 the `/' which is suspected to open a comment, instead of being
15682 called after `//' or `/*' was read.

15684 (copy_guard): Adjust.
15686 2000-10-16 Akim Demaille <akim@epita.fr>
15688 * src/reader.c (parse_expect_decl): Use `skip_white_space' and
15689 `read_signed_integer'.
15691 2000-10-16 Akim Demaille <akim@epita.fr>
15693 * src/reader.c (copy_dollar): New function.
15694 (copy_guard, copy_action): Use it.
15696 2000-10-16 Akim Demaille <akim@epita.fr>
15698 * lib/quote.h, lib/quote.c, lib/quotearg.h, lib/quotearg.c:
15699 * m4/prereq.m4, m4/c-bs-a.m4, m4/mbstate.m4:
15700 New files, from Fileutils 4.0.27.
15701 * src/main.c (printable_version): Remove.

15708 2000-10-04 Akim Demaille <akim@epita.fr>
15710 * doc/bison.texinfo: Various typos spotted by Neil Booth.
15712 2000-10-04 Akim Demaille <akim@epita.fr>
15714 When a literal string is used to define two different tokens,
15715 `bison -v' segfaults.
15716 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
15718 * tests/regression.m4: New file.
15719 Include the core of the sample provided by Piotr Gackiewicz.
15720 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
15723 2000-10-04 Akim Demaille <akim@epita.fr>
15725 * src/reader.c (parse_expect_decl): Keep `count' within the size
15729 2000-10-02 Paul Eggert <eggert@twinsun.com>

15735 2000-10-02 Akim Demaille <akim@epita.fr>
15737 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
15740 2000-10-02 Akim Demaille <akim@epita.fr>
15742 * src/derives.c, src/print.c, src/reduce.c: To ease the
15743 translation, move some `\n' out of the translated strings.
15745 2000-10-02 Akim Demaille <akim@epita.fr>
15747 The location tracking mechanism is precious for parse error
15748 messages. Nevertheless, it is enabled only when `@n' is used in
15749 the grammar, which is a different issue (you can use it in error
15750 message, but not in the grammar per se). Therefore, there should
15751 be another means to enable it.
15753 * src/getargs.c (getargs): Support `--locations'.
15754 (usage): Report it.
15755 * src/getargs.h (locationsflag): Export it.
15756 * src/lex.c (percent_table): Support `%locations'.
15757 * src/reader.c (yylsp_needed): Remove this variable, now replaced
15758 with `locationsflag'.
15759 * doc/bison.texinfo: Document `--locations' and `%locations'.
15761 * tests/calc.m4: Test it.
15763 For regularity of the names, replace each
15764 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
15765 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
15766 In addition replace each `flag' with `_flag'.
15768 2000-10-02 Akim Demaille <akim@epita.fr>
15770 Also test parse error messages, including with YYERROR_VERBOSE.
15772 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
15774 Use it to check the computations.
15775 Use it to check `nonassoc' is honored.
15776 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
15777 `--yyerror-verbose'.
15778 (_AT_CHECK_CALC): Adjust to this option.
15779 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
15781 2000-10-02 Akim Demaille <akim@epita.fr>
15783 Test also `--verbose', `--defines' and `--name-prefix'. Testing
15784 the latter demonstrates a flaw in the handling of non debugging
15785 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
15786 was used in order to simplify:
15802 unfortunately this leads to a CPP conflict when
15803 `--name-prefix=foo' is used since it produces `#define yydebug
15806 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
15807 (YYDPRINTF): New macro.
15809 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
15811 Also test `--verbose', `--defines' and `--name-prefix'.

15815 Improve the readability of the produced parsers.
15817 * src/bison.s1: Formatting changes.
15818 Improve the comment related to the `$' mark.
15819 (yydefault): Don't fall through to `yyresume': `goto' there.
15820 * src/output.c (output_parser): When the `$' is met, skip the end
15822 New variable, `number_of_dollar_signs', to check there's exactly
15823 one `$' in the parser skeleton.
15825 2000-10-02 Akim Demaille <akim@epita.fr>
15827 * lib/xstrdup.c: New file, from the fileutils.
15828 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
15829 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
15830 instead of strlen + xmalloc + strcpy.
15831 * src/symtab.c (copys): Remove, use xstrdup instead.
15833 2000-10-02 Akim Demaille <akim@epita.fr>
15835 * src/gram.h (associativity): New enum type which replaces the
15836 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
15837 `right_assoc', `left_assoc' and `non_assoc'.
15838 Adjust all dependencies.
15839 * src/reader.c: Formatting changes.
15840 (LTYPESTR): Don't define it, use it as a literal in
15841 `reader_output_yylsp'.
15842 * src/symtab.h (symbol_class): New enum type which replaces the
15843 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with

15852 2000-10-02 Akim Demaille <akim@epita.fr>
15854 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
15855 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
15856 difficult and introduced a lot of core dump. It turns out that
15857 Bison used an implementation of `xmalloc' based on `calloc', and
15858 at various places it does depend upon the initialization to 0. I
15859 have not tried to isolate the pertinent places, and all the former
15860 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
15861 someone should address this issue.
15863 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
15864 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

15958 * src/output.c (token_actions): Introduce a temporary array,
15959 YYDEFACT, that makes it possible for this function to use
15960 output_short_table.
15962 2000-10-02 Akim Demaille <akim@epita.fr>
15964 `user_toknums' is output as a `short[]' in `output.c', while it is
15965 defined as a `int[]' in `reader.c'. For consistency with the
15966 other output tables, `user_toknums' is now defined as a table of

16010 * src/system.h: Define PARAMS.

16231 Change the handling of @s so that they behave exactly like $s.
16232 There is now a pseudo variable @$ (readble and writable), location
16233 of the lhs of the rule (by default ranging from the location of
16234 the first symbol of the rhs, to the location of the last symbol,
16235 or, if the rhs is empty, YYLLOC).
16237 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
16239 (yyparse): When providing a default semantic action, provide a
16240 default location action.

16242 same way you stack YYVAL.
16243 * src/reader.c (read_declarations): Use warns.
16244 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.

16270 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

16949 declaration to allow a multi-character symbol as an alias.
16950 (parse_thong_decl): New function.
16951 (read_declarations): Added %thong declarations.
16952 (read_declarations): Handle NOOP to deal with allowing
16953 % declarations as another means to specify the flags.
16954 (readgram): Allow %prec prior to semantics embedded in a rule.
16955 (skip_to_char, read_declarations, copy_definition)
16956 (parse_token_decl, parse_start_decl, parse_type_decl)
16957 (parse_assoc_decl, parse_union_decl, parse_expect_decl)
16958 (get_type_name, copy_guard, copy_action, readgram)
16959 (get_type, packsymbols): Revised most error messages.
16960 Changed `fatal' to `warnxxx' to avoid aborting for error.
16961 Revised and use multiple warnxxx functions to avoid using VARARGS1.
16962 (read_declarations): Improve the error message for
16963 an invalid character. Do not abort.
16964 (read_declarations, copy_guard, copy_action): Use
16965 printable_version to avoid unprintable characters in printed output.
16966 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
16967 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
16968 Allow the type of a non-terminal can be given
16969 more than once, as long as all specifications give the same type.
16972 (output_headers, output_trailers, output, output_gram)
16973 (output_rule_data): Implement noparserflag variable.
16974 Implement toknumflag variable.
16975 (output): Call reader_output_yylsp to output LTYPESTR.
16977 * src/main.c (main):
16978 If reader sees an error, don't process the grammar.
16979 (fatals): Updated to not use VARARGS1.
16980 (printable_version, int_to_string, warn, warni, warns, warnss)
16981 (warnsss): New error reporting functions. Avoid abort for error.
16984 Added THONG and NOOP for alias processing.
16985 Added SETOPT for the new code that allows setting options with %flags.
16988 Include getopt.h. Add some extern decls.
16989 (safegetc): New function to deal with EOF gracefully.
16990 (literalchar); new function to deal with reading \ escapes.
16991 (lex): Use literalchar.
16992 (lex): Implemented "..." tokens.
16993 (literalchar, lex, parse_percent_token): Made tokenbuffer
16994 always contain the token. This includes growing the token
16995 buffer while reading an integer.
16996 (parse_percent_token): Replaced if-else statement with percent_table.
16997 (parse_percent_token): Added % declarations as another
16998 way to specify the flags -n, -l, and -r. Also added hooks for
16999 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
17000 major changes to files.c.
17001 (lex) Retain in the incoming stream a character following
17003 (skip_white_space, lex): Revised most error messages
17004 and changed fatal to warn to avoid aborting.
17005 (percent_table): Added %thong declarations.
17007 * src/gram.h: Comment changes.
17009 * src/files.c (openfiles, open_extra_files, done):
