3 * bootstrap: Sync from coreutils, as follows:
5 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
7 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
8 variable was sometimes used without being initialized. This
9 messed up the installation of the INSTALL file in some cases.
11 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
13 * bootstrap (usage, main program, symlink_to_gnulib): Add option
14 --copy. Inspired by a suggestion from Bruno Haible.
16 2006-10-03 Jim Meyering <jim@meyering.net>
18 * bootstrap: Undo last change to this file, since now gnulib-tool
19 sticks with the automake default in generating dependencies.
21 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
23 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than
24 the old AC_PROG_CC / AM_PROG_CC_STDC combination.
26 * doc/bison.1: Add copyright notice.
28 * data/glr.c: Don't include <stdarg.h>; not used.
30 * NEWS: The -g and --graph options now output graphs in Graphviz
31 DOT format, not VCG format.
32 * doc/bison.1: Likewise.
33 * doc/bison.texinfo (Understanding, Bison Options): Likewise.
34 * THANKS: Add Satya Kiran Popuri, who proposed the initial version
36 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00158.html>.
37 * TODO: Remove Graphviz entry.
38 * src/Makefile.am (bison_SOURCES): Add graphviz.c and graphviz.h;
39 remove vcg.c, vcg.h, vcg_defaults.h.

43 * src/files.h: Make comment more generic.
44 * src/main.c (main): Likewise.
45 * src/print_graph.h: Likewise.
46 * src/getargs.c (usage): Make usage description more generic.
47 * src/print_graph.c: Include graphviz.h rather than vcg.h.
48 (static_graph, fgraph): Remove. All uses changed to pass
49 arguments instead of sharing a static var.
50 (print_core, print_actions, print_state, print_graph):
51 Output graphviz format rather than VCG format.
52 * tests/.cvsignore: Remove *.vcg; add *.dot.
53 * tests/output.at: Expect *.dot files, not *.vcg files.
55 * data/Makefile.am (dist_pkgdata_DATA): Add bison.m4; this
56 accommodates the 2006-10-08 change.
58 2006-10-11 Bob Rossi <bob@brasko.net>
60 * data/push.c (yypushparse, yypvarsinit, yypvars): Wrap in b4_push_if.
61 (b4_yyssa, b4_yyerror_range): New macros.
62 (struct yypvars): Remove yyssa_ptr and yyerror_range_ptr fields.
63 (yypvarsinit): Remove init of removed fields.

66 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
68 * data/push.c (yypushparse): Fix memory leak if yymsg is malloced
69 in a push parser. Reindent slightly to match yacc.c better.
71 2006-10-11 Bob Rossi <bob@brasko.net>
73 * data/push.c (struct yypvars): Remove yymsgbuf, yymsgbuf_ptr, yymsg,
75 (yypvarsinit, yypushparse): Remove init of removed fields.
76 (yypushparse): Use yymsgbuf instead of yymsgbuf_ptr.
78 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
80 * THANKS: Add Paolo Bonzini and Bob Rossi.
82 2006-10-08 Paolo Bonzini <bonzini@gnu.org>
84 * data/c.m4 (b4_copyright, b4_epilogue, b4_location_initial_column,
85 b4_location_initial_line, p4_parse_param, b4_ints_in, b4_flag_if,
86 b4_define_flag_if and uses, b4_basename, b4_syncline, b4_user_code,
87 b4_define_user_cde and uses): Remove.
88 (b4_comment, b4_prefix, b4_sync_start): New.
89 * data/bison.m4: New file, with most of the content removed from c.m4.
90 * src/muscle_tab.h: Use "do {...} while(0)" throughout.
91 * src/output.c (output_skeleton): Pass bison.m4.
92 (prepare): Pass glr_flag and nondeterministic_flag. Pass prefix
95 2006-10-05 Paul Eggert <eggert@cs.ucla.edu>
97 Fix test failure reported by Tom Lane in
98 <http://lists.gnu.org/archive/html/bug-bison/2006-10/msg00000.html>
99 and try to make such failures easier to catch in the future.
100 * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
101 that's now the caller's responsibility.
102 (yyprocessOneStack, yyrecoverSyntaxError, yyparse):
103 Set yychar = YYEOF if it's negative.
104 * tests/actions.at (yylex): Abort if asked to read past EOF.
105 * tests/conflicts.at (yylex): Likewise.
106 * tests/cxx-type.at (yylex): Likewise.
107 * tests/glr-regression.at (yylex): Likewise.
108 * tests/input.at (yylex): Likewise.
109 * tests/regression.at (yylex): Likewise.
110 * tests/torture.at (yylex): Likewise.
112 2006-10-01 Paul Eggert <eggert@cs.ucla.edu>
114 Fix problems with translating English-language diagnostics.
115 * bootstrap: Fix bug introduced in recent bootstrap changes, with
116 respect to bison-runtime pot generation. The YY_ stuff
117 wasn't being captured.
118 * bootstrap.conf (XGETTEXT_OPTIONS_RUNTIME): New var.
119 * po/POTFILES.in: Add src/location.c, src/scan-code.l.
120 * runtime-po/POTFILES.in: Add data/push.c.
122 2006-09-29 Paul Eggert <eggert@cs.ucla.edu>
124 Merge bootstrap changes from coreutils.
126 2006-09-28 Jim Meyering <jim@meyering.net>
128 Automatically generated dependencies are important even
129 when all of the sources in a directory come from gnulib.
130 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
131 option that gnulib-tool adds to what becomes our lib/gnulib.mk.
133 2006-09-23 Jim Meyering <jim@meyering.net>
135 * bootstrap (gnulib_tool_options): Add "--local-dir gl".
137 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
139 * bootstrap: Add support for --force.
140 (usage): New function. Describe usage less tersely.
141 (CVS_only_file): New var.
143 2006-09-21 Paul Eggert <eggert@cs.ucla.edu>
145 * data/push.c (YYPUSH_MORE): Make it an enum instead.
146 (yypushparse): Use YYPUSH_MORE instead of the mystery constant.
147 Adjust white space and comments to match GNU style better.
149 2006-09-20 Bob Rossi <bob@brasko.net>
151 * data/push.c (yyresult_get): Remove function.
152 (YYPUSH_MORE): Add #define.
153 (yypushparse): Modify return value.
155 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
157 * stamp-h.in: Remove; no longer needed.
158 * .cvsignore: Replace autom4te.cache and config.cache with *.cache.
159 Remove config.h, config.hin, intl (no longer created).
160 * lib/.cvsignore: Add config.h, config.hin, configmake.h, inttypes.h,
163 Sync bootstrap from coreutils, as follows:
165 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
167 * bootstrap (symlink_to_gnulib): New function.
168 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
170 (cp_mark_as_generated, slurp, gnulib_files):
171 Avoid making a copy if it's the same as the old version.
172 (gnulib_files): Add support for this variable (used by Bison).
174 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
176 * src/getargs.c (usage): Rework to use conventions similar to
177 coreutils, to make translation a bit easier and the code a bit
178 smaller. Problem reported by Tim Van Holder.
180 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
182 Use some of gnulib's new modules, taken from coreutils.
184 * bootstrap: Sync from coreutils, except add support for gnulib_files.
185 * bootstrap.conf: New file.
186 (gnulib_modules): Add configmake, inttypes, unistd.
187 (XGETTEXT_OPTIONS): Add complain, complain_at,
188 fatal, fatal_at, warn, warn_at, unexpected_end.
189 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
190 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
192 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
194 (GNULIB_AUTOCONF_SNIPPET): Remove.
195 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
197 * lib/.cvsignore: Add inttypes_.h.
198 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
199 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
200 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
201 no-longer-necessary initializations.
202 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
203 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
204 use the unistd module.
205 * src/system.h: Likewise.
206 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
207 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
208 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
209 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
210 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
211 * src/system.h: Include inttypes.h unconditionally, now that we
212 use the inttypes module. Don't bother to include stdint.h, since
213 inttypes.h now does that for us.
214 (LOCALEDIR): Remove, now that we use the configmake module.
215 * src/getargs.c: Include configmake.h.
216 * src/main.c: Likewise.
217 * src/output.c: Likewise.
218 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
219 not from $abs_top_builddir, since config.h moved.
222 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
223 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
225 * src/parse-gram.y (symbol_declaration): Don't put statements
226 before declarations; it's not portable to C89.
227 * src/scan-code.l (handle_action_at): Likewise.
229 * src/scan-code.l: Always initialize braces_level; the old code
230 left it uninitialized and therefore had undefined behavior.
232 Don't attempt to redefine 'assert', since it runs afoul of
233 systems where standard headers (mistakenly) include <assert.h>.
234 Instead, define and use our own alternative, called 'aver'.
235 * src/reader.c: Don't include assert.h, since we no longer
237 * src/scan-code.l: Likewise.
238 * src/system.h (assert): Remove, replacing with....
239 (aver): New function, taking a bool arg. All uses changed.
240 * src/tables.c (pack_vector): Ensure that aver arg is bool,
241 not merely an integer.
243 2006-09-15 Bob Rossi <bob@brasko.net>
245 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
246 * data/c.m4 (YYPUSH): New.
247 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
248 * src/getargs.c (push_parser): New var.
249 * src/getargs.h (push_parser): New declaration.
250 * src/output.c (prepare): Add macro insertion of `push_flag'.
251 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
252 (prologue_declaration): Parse %push-parser.
253 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
254 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
255 list of removed lines from the traces observed.
256 (AT_CHECK_CALC_LALR): Added push parser tests.
258 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
260 * NEWS: Version 2.3a.
261 * configure.ac (AC_INIT): Likewise.
263 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
264 "#define YYSTYPE int" that caused "make maintainer-check" to fail
265 due to header ordering dependencies. I don't know why the #define
268 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
269 runtime cost when YYDEBUG is not defined, and so that some tests
270 that used to fail now work. Problem and initial suggestion by
272 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
273 * data/glr.cc (b4_parser_class_name):
274 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
275 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
276 (yydebug_) [YYDEBUG]: New member.
277 (yycdebug_): Now defined only if YYDEBUG.
278 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
279 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
280 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
282 (debug_stream, set_debug_stream, debug_level, set_debug_level):
283 Define only if YYDEBUG.
284 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
286 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
287 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
288 AT_CHECK_CALC_GLR_CC that are working now.
290 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
292 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
293 We don't need them in glr.cc, and glr.c defines them.
294 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
295 assumes that defining it to anything is the same as defining
296 it to 1. Problem reported by Paolo Bonzini.
298 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
300 * data/c.m4 (b4_null, b4_case): Define.
301 * src/output.c (prepare_symbols): Use b4_null.
302 (user_actions_output): Use b4_case.
304 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
306 * data/glr.c (b4_shared_declarations): Put start-header first,
307 before any #includes that we generate, so that feature-test
308 macros work. Problem reported by Michael Deutschmann in
309 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
310 * data/lalr1.cc: Likewise.
311 * doc/bison.texinfo (Prologue): Document that feature-test macros
312 should be defined before any Bison declarations.
313 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
314 that depend on location.hh after, not before, Bison decls, since
315 we now include location.hh after the first user prologue.
317 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
318 Sander Brandenburg in
319 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
320 Also, fix minor white space and comment issues.
321 (Prologue): Mention that it's better to define feature-test macros
322 before Bison declarations. Problem reported by Michael Deutschmann.
324 * README-cvs: Fix typo: "&" should be "&&". Problem reported
326 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
327 This adjusts to recent gnulib changes.
329 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
331 Finish implementation of per-type %destructor/%printer. Discussed
333 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
335 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
336 * NEWS (2.3+): Add a description of this feature to the default
337 %destructor/%printer description.
338 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
339 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
340 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
341 list node contains a semantic type.
342 * src/symtab.c, src/symtab.h: Extend with a table that associates
343 semantic types with their %destructor's and %printer's.
344 (semantic_type_from_uniqstr, semantic_type_get,
345 semantic_type_destructor_set, semantic_type_printer_set): New functions
346 composing the public interface of that table.
347 (symbol_destructor_get, symbol_destructor_location_get,
348 symbol_printer_get, symbol_printer_location_get): If there's no
349 per-symbol %destructor/%printer, look up the per-type before trying
351 * tests/actions.at (Per-type %printer and %destructor): New test case.
352 * tests/input.at (Default %printer and %destructor redeclared):
353 Extend to check that multiple occurrences of %symbol-default in a
354 single %destructor/%printer declaration is an error.
355 (Per-type %printer and %destructor redeclared, Unused values with
356 per-type %destructor): New test cases.
358 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
360 Require default %destructor/%printer to be declared using
361 %symbol-default instead of an empty symbol list, and start working on
362 new per-type %destructor/%printer. Discussed at
363 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
364 * NEWS (2.3+): Add %symbol-default to example.
365 * bison.texinfo (Freeing Discarded Symbols): Likewise.
366 (Bison Symbols): Add entry for %symbol-default.
367 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
368 (generic_symlist, generic_symlist_item): New nonterminals for creating
369 a list in which each item is a symbol, semantic type, or
371 (grammar_declaration): Use generic_symlist in %destructor and %printer
372 declarations instead of symbols.1 or an empty list.
373 (symbol_declaration, precedence_declaration, symbols.1): Update actions
374 for changes to symbol_list.
375 * src/reader.c: Update for changes to symbol_list.
376 * src/scan-code.l: Likewise.
377 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
378 * src/symlist.c, src/symlist.h: Extend such that a list node may
379 represent a semantic type or a %symbol-default in addition to just an
380 ordinary symbol. Add switched functions for setting %destructor's and
382 * tests/actions.at, tests/input.at: Add %symbol-default to all default
383 %destructor/%printer declarations.
385 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
387 Whether the default %destructor/%printer applies to a particular symbol
388 isn't a question of whether the user *declares* that symbol (in %token,
389 for example). It's a question of whether the user by any means
390 *defines* the symbol at all (by simply using a char token, for
391 example). $end is defined by Bison whereas any other token with token
392 number 0 is defined by the user. The error token is always defined by
393 Bison regardless of whether the user declares it with %token, but we
394 may one day let the user define error as a nonterminal instead.
395 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
396 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
397 the meaning of "user-defined".
398 * tests/actions.at (Default %printer and %destructor for user-declared
399 end token): Rename to...
400 (Default %printer and %destructor for user-defined end token): ...
403 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
404 computation of whether to apply the default, don't maintain a list of
405 every Bison-defined symbol. Instead, just check for a first character
406 of '$', which a user symbol cannot have, and check for the error token.
408 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
410 Don't apply the default %destructor or %printer to the error token,
411 $undefined, or $accept. This change fits the general rule that the
412 default %destructor and %printer are only for user-declared symbols,
413 and it solves several difficulties that are described in the new test
415 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
416 * tests/actions.at (Default %printer and %destructor are not for error
417 or $undefined, Default %printer and %destructor are not for $accept):
420 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
422 Allow %start after the first rule.
423 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
424 when parsing the first rule.
425 (check_and_convert_grammar): Search for it here after all grammar
426 declarations have been parsed. Skip midrules, which have dummy LHS
428 * src/symtab.c (symbol_is_dummy): New function.
429 * src/symtab.h (symbol_is_dummy): Declare it.
430 * tests/input.at (%start after first rule): New test.
432 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
434 Redo some of the previous commit: add back the ability to use
435 non-aliased/undeclared string literals since it might be useful to
436 those declaring %token-table.
437 * src/reader.c (check_and_convert_grammar): Undo changes in previous
438 commit: don't worry about complaints from symbols_pack.
439 * src/symtab.c (symbol_new, symbol_class_set,
440 symbol_check_alias_consistency): Undo changes in previous commit: count
441 each string literal as a new symbol and token, assign it a symbol
442 number, and don't complain about non-aliased string literals.
443 (symbols_pack): Since symbol_make_alias still does not decrement symbol
444 and token counts but does still set aliased tokens to the same number,
445 symbol_pack_processor now leaves empty slots in the symbols array.
447 * tests/regression.at (Undeclared string literal): Remove test case
448 added in previous commit since non-aliased string literals are allowed
450 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
451 remove unnecessary string literal declarations.
452 * tests/sets.at (Firsts): Likewise.
454 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
456 Don't allow an undeclared string literal, but allow a string literal to
457 be used before its declaration.
458 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
459 symbols_pack complained.
460 * src/symtab.c (symbol_new): Don't count a string literal as a new
462 (symbol_class_set): Don't count a string literal as a new token, and
463 don't assign it a symbol number since symbol_make_alias does that.
464 (symbol_make_alias): It's not necessary to decrement the symbol and
465 token counts anymore. Don't assume that an alias declaration occurs
466 before any uses of the identifier or string, and thus don't assert that
467 one of them has the highest symbol number so far.
468 (symbol_check_alias_consistency): Complain if there's a string literal
469 that wasn't declared as an alias.
470 (symbols_pack): Bail if symbol_check_alias_consistency failed since
471 symbol_pack asserts that every token has been assigned a symbol number
472 although undeclared string literals have not.
473 * tests/regression.at (String alias declared after use, Undeclared
474 string literal): New test cases.
475 (Characters Escapes, Web2c Actions): Declare string literals as
477 * tests/sets.at (Firsts): Likewise.
479 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
481 In the grammar scanner, STRING_FINISH unclosed constructs and return
482 them to the parser in order to improve error messages.
483 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
484 SC_BRACED_CODE, SC_PROLOGUE): Implement.
485 * tests/input.at (Unclosed constructs): New test case.
486 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
489 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
492 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
494 Handle string aliases for character tokens correctly.
495 * src/symtab.c (symbol_user_token_number_set): If the token has an
496 alias, check and set its alias's user token number instead of its own,
497 which is set to indicate the alias. Previously, every occurrence of
498 the character token in the grammar overwrote that alias indicator with
500 * tests/input.at (String aliases for character tokens): New test.
502 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
504 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
506 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
508 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
509 to prevent failures when building on older platforms.
510 Check for autopoint failure.
511 Set XGETTEXT_OPTIONS to values that check for C format strings,
512 so that translators are warned about them (this also helps
515 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
516 function, since it simplifies our code a bit.
518 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
519 rather than -W, so we don't get bogus warnings about sign comparisons.
520 Add -Wpointer-arith, since that warning is useful (it reports code
521 that does not conform to C89 and that some compilers reject).
522 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
523 since it's no longer needed.
525 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
527 Clean up scanners a bit.
528 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
529 definitions so gcc won't warn when obstack_for_string is unused.
530 * src/scan-code.l: config.h and system.h are already #include'd by
531 scan-code-c.c, so get rid of them here.
532 * src/scan-gram.l: Likewise.
533 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
534 definitions rather than duplicating the rest of it.
535 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
537 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
539 Suppress signed/unsigned comparison warnings for yycheck.
540 * data/c.m4 (b4_safest_int_type): New macro.
541 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
542 a signed int type, cast it to b4_safest_int_type first.
543 * data/yacc.c: Likewise.
544 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
547 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
549 * doc/bison.texinfo: Fix some typos.
551 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
553 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
554 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
556 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
557 the latest gnulib does this a different way.
558 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
559 translation was patched, so stop omitting it.
561 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
563 Enable declaration of default %printer/%destructor. Make the parser
564 use these for all user-declared grammar symbols for which the user does
565 not declare a specific %printer/%destructor. Thus, the parser uses it
566 for token 0 if the user declares it but not if Bison generates it as
567 $end. Discussed starting at
568 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
569 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
571 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
572 * NEWS (2.3+): Mention.
573 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
574 declare a %destructor for a mid-rule's semantic value. It's just
575 impossible to declare one specific to it.
576 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
577 code. Describe default %destructor form.
578 * src/parse-gram.y (grammar_declaration): Parse default
579 %printer/%destructor declarations.
580 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
581 and symbol_destructor_location_get rather than accessing the destructor
582 and destructor_location members of struct symbol.
583 (symbol_printers_output): Likewise but for %printer's.
584 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
586 * src/symtab.c (default_destructor, default_destructor_location,
587 default_printer, default_printer_location): New static global
588 variables to record the default %destructor and %printer.
589 (symbol_destructor_get, symbol_destructor_location_get,
590 symbol_printer_get, symbol_printer_location_get): New functions to
591 compute the appropriate %destructor and %printer for a symbol.
592 (default_destructor_set, default_printer_set): New functions to set the
593 default %destructor and %printer.
594 * src/symtab.h: Prototype all those new functions.
595 * tests/actions.at (Default %printer and %destructor): New test to
596 check that the right %printer and %destructor are called, that they're
597 not called for $end, and that $$ and @$ work correctly.
598 (Default %printer and %destructor for user-declared end token): New
599 test to check that the default %printer and %destructor are called for
600 a user-declared end token.
601 * tests/input.at (Default %printer and %destructor redeclared, Unused
602 values with default %destructor): New tests to check related grammar
605 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
607 Clean up handling of %destructor for the end token (token 0).
608 Discussed starting at
609 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
611 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
613 Make the skeletons consistent in how they pop the end token and invoke
615 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
616 state, which has token number 0, since this would invoke the
617 %destructor for the end token.
618 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
619 until after shifting the end token, or else it won't be popped.
620 * data/yacc.c (yyparse): Likewise.
622 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
623 it's the end token. Upon termination, destroy an unshifted lookahead
624 even when it's the end token.
625 * data/lalr1.cc (yy::parser::parse): Likewise.
626 * data/yacc.c (yyparse): Likewise.
628 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
629 value warnings for the end token when the user gives the end token a
632 * tests/actions.at (Printers and Destructors): Test all the above.
634 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
636 Update to latest gnulib and gettext versions.
637 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
639 (gnulib_files): Add m4/warning.m4. Don't worry about files
640 overwritten by autopoint.
641 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
642 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
644 Don't use autoreconf; instead, invoke autopoint etc. by hand,
645 so that we can remove the intl files at a better time.
646 (intl_files_to_remove): Remove aclocal.m4, since it gets
647 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
648 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
649 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
650 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
651 Remove datarootdir hack; no longer needed.
652 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
653 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
654 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
656 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
657 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
659 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
661 * bootstrap: Adjust to today's change to gnulib-tool by invoking
662 it with --assume-autoconf='latest-stable'.
664 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
666 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
667 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
669 * src/muscle_tab.h (muscle_grow): Replace the header comments with
670 those from muscle_tab.c since the old ones are misleading.
672 2006-07-13 Akim Demaille <akim@epita.fr>
674 Support %define "KEY" {VALUE}.
675 * src/scan-code.h, src/scan-code.l (translate_action)
676 (translate_rule_action, translate_symbol_action, translate_code):
677 Return char *, not const char *.
678 * src/parse-gram.y (declaration): Rename as...
679 (prologue_declaration): this.
680 (string_content): Remove this nonterminal, use STRING.
681 (braceless, content, content.opt): New nonterminal.
683 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
685 * src/scan-gram.l (getargs.h): Don't include it.
687 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
689 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
690 rather than a for-loop that declares a local bool variable. This
691 should work around a compatibility problem with a Cray x1e C++
692 compiler reported by Hung Nguyen in
693 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
694 The for-loop was introduced in the 2004-11-17 change but I don't
695 know why it was needed.
697 2006-07-12 Akim Demaille <akim@epita.fr>
699 * data/c.m4: Comment changes.
701 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
703 * src/complain.c (error_message, ERROR_MESSAGE): New.
705 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
706 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
708 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
710 * NEWS: Instead of %union, you can define and use your own union type
711 YYSTYPE if your grammar contains at least one <type> tag.
712 Your YYSTYPE need not be a macro; it can be a typedef.
713 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
714 (Union Decl, Decl Summary): Document this.
715 * data/glr.c (YYSTYPE): Implement this.
716 * data/glr.cc (YYSTYPE): Likewise.
717 * data/lalr1.cc (YYSTYPE): Likewise.
718 * data/yacc.c (YYSTYPE): Likewise.
719 * src/output.c (prepare): Output tag_seen_flag.
720 * src/parse-gram.y (declaration, grammar_declaration):
721 Use 'union_seen' rather than 'typed' to determine whether
722 %union has been seen, since grammars can now be typed without
724 (symbol_declaration, type.opt, symbol_def):
725 Keep track of whether a tag has been seen.
726 * src/reader.c (union_seen, tag_seen): New vars.
728 * src/reader.h (union_seen, tag_seen, typed): Likewise.
729 * src/scan-code.l (untyped_var_seen): New variable.
730 (handle_action_dollar): Adjust to above changes.
731 (handle_action_dollar, handle_action_at):
732 Improve overflow checking for outlandish numbers.
733 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
734 avoid new diagnostics generated by above changes.
735 * tests/regression.at (YYSTYPE typedef): Add test to check
736 for type tags without %union.
738 * src/symlist.c (symbol_list_length): Return int, not unsigned
739 int, since callers expect int. This may need to get revisited
740 once we have proper integer overflow checking.
742 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
743 object is now static.
745 * src/getargs.c (flags_argmatch): Return void, not int,
746 to pacify ./configure --enable-gcc-warnings.
748 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
749 since last_string is already defined to FLEX_PREFIX (last_string).
751 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
753 Implement --warnings/-W.
754 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
756 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
758 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
759 (warnings_args, warnings_types): New.
760 (getargs, short_options, long_options): Accept -W/--warnings.
761 Sort the options by alphabetical order, upper case letter right
762 before its lower case.
764 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
766 Change %merge result type clash warnings to errors. Discussed at
767 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
768 * src/reader.c (record_merge_function_type): Use complain_at.
769 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
770 declared later): Update test case results.
772 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
774 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
775 to be in alphabetical order.
776 (trace_args): Spelling fixes.
778 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
780 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
781 so they don't collide with user-defined macros.
782 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
783 this was never guaranteed, and now that we're using gnulib stdint,
784 which defines int_fast16_t to long int, the problem is exposed.
786 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
788 * data/c.m4 (b4_basename): Simplify a bit, since we don't
789 need the full POSIX semantics (and weren't implementing them
792 Adjust to Autoconf 2.60 and today's gnulib.
793 * bootstrap (gnulib_modules): Add stdint.
794 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
796 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
797 since stdint needs the former and wcwidth (which is now required
798 by mbswidth) needs the latter.
799 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
800 work around a compatibility glitch between gettext 0.14.6 and
802 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
803 Do not check for uintptr_t, since new stdint module does the right
805 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
806 Add stdint.h, stdint_.h, wcwidth.h.
807 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
808 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
809 stdint.m4, wchar_t.m4, wcwidth.m4.
810 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
811 usual order for ../lib/*.h files.
812 (file_name_split): Use last_component, not base_name, to adjust
814 * src/parse-gram.h: Include <strverscmp.h> in the usual order
815 for ../lib/*.h files.
816 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
817 Define unconditionally, since we now assume the stdint module.
818 * src/scan-skel.l: Include <dirname.h>.
819 (BASE_QPUTS): Use last_component, not base_name.
820 * src/system.h: Include <unlocked-io.h> in the usual order
821 for ../lib/*.h files. Include <stdint.h> unconditionally,
822 since we now use the stdint module.
823 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
824 HAVE_UINTPTR_T, since we now use the stdint module.
825 (base_name): Remove decl, since files now include <dirname.h>
828 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
830 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
832 * data/yacc.c, data/glr.c, data/location.cc: Use them.
833 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
835 * tests/calc.at: Adjust.
837 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
839 * data/c.m4 (b4_basename): New.
840 (b4_syncline): Also output the location of its invocation (from
842 (b4_user_action, b4_define_user_action, b4_user_actions)
843 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
844 (b4_user_stype): New.
845 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
847 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
849 In the grammar file, the first column is 1 not 0 on the first line as
851 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
852 * tests/input.at (Torturing the Scanner): Update output.
854 * src/scan-gram.l (scanner_cursor): Declare it static.
856 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
858 In warnings, say "previous declaration" rather than "first
860 * src/symtab.c (redeclaration): Do that here.
861 * src/reader.c (record_merge_function_type): In the case of a result
862 type clash, report the previous declaration rather than the very first
863 one in the grammar file.
864 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
865 declared later): Add a third declaration to check this behavior.
866 * tests/input.at (Incompatible Aliases): Update output.
868 2006-06-27 Akim Demaille <akim@epita.fr>
870 * doc/Doxyfile.in: New.
871 * doc/Makefile.am: Use it.
872 * src/lalr.h, src/symtab.h: Initial doxygenation.
874 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
876 Don't miss %merge result type warnings just because the LHS types are
877 declared after the %merge. This continues the effort of the previous
879 * src/reader.c (get_merge_function): Don't set the merger type yet.
880 (record_merge_function_type): New function for setting the merger type
881 and checking for clashes.
882 (grammar_current_rule_merge_set): Set the location of the %merge for
884 (packgram): Invoke record_merge_function_type for each rule now that
885 all symbol type declarations have been parsed.
886 * src/reader.h (merger_list.type_declaration_location): New member
887 storing the location of the first %merge from which the type for this
888 merging function was derived.
889 * src/symlist.h (symbol_list.merger_declaration_location): New member
890 storing the location of a rule's %merge, if any.
891 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
892 declared later): New test to catch the error fixed by the above patch.
894 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
896 Get action warnings (grammar_rule_check) right even when symbol
897 declarations appear after the rules. Discussed at
898 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
900 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
901 Don't mistake the type of $$ in a midrule to be that of its parent
903 * src/reader.c (grammar_current_rule_end): Don't invoke
904 grammar_rule_check yet since not all symbol declarations may have been
906 (grammar_midrule_action): Likewise.
907 Don't record whether the midrule's $$ has been used yet since actions
908 haven't been translated yet.
909 Record the midrule's parent rule and its RHS index within the parent
911 (grammar_current_rule_action_append): Don't translate the action yet
912 since not all symbol declarations may have been parsed yet and, thus,
913 warnings about types for $$, $n, @$, and @n can't be reported yet.
914 (packgram): Translate the action and invoke grammar_rule_check now that
915 all symbol declarations have been parsed.
916 * src/scan-code.l (handle_action_dollar): Now that this is invoked
917 after parsing the entire grammar file, the symbol list here in the case
918 of a midrule is actually the midrule's empty RHS, so reference its
919 parent rule's RHS where necessary.
920 On the other hand, now that you can already know it's a midrule, you
921 aren't forced to think $$ has the same type as its parent rule's $$.
922 (handle_action_at): In the case of a midrule, reference the parent rule
924 * src/symlist.c (symbol_list_new): Initialize new midrule-related
926 (symbol_list_length): Now that this is invoked after all rules have
927 been parsed, a NULL symbol (rather than a NULL symbol list node)
928 terminates a rule. symbol_list_print already does this correctly.
929 * src/symlist.h (symbol_list.midrule_parent_rule,
930 symbol_list.midrule_parent_rhs_index): New members so that midrules can
931 remember their relationships with their parents.
932 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
933 fixed by the above patch.
934 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
936 (Unused values): ... this old test case and...
937 (Unused values before symbol declarations): ... this new test case.
938 This one is the same as `Unused values' except that all symbol
939 declarations appear after the rules in order to catch the rest of the
940 errors fixed by the above patch.
942 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
945 * src/reader.c (current_rule): Declare it static since it's no longer
946 used outside this file.
947 (grammar_current_rule_action_append): Remove redundant arguments from
948 translate_rule_action invocation.
949 * src/reader.h (current_rule): Remove this unused extern.
950 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
951 * src/scan-code.l (translate_rule_action): Likewise.
953 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
955 Clean up yesterday's patch.
956 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
958 * src/reader.c (grammar_current_rule_action_append): ... here for
959 consistency with grammar_current_rule_symbol_append.
960 * tests/regression.at (Braced code in declaration in rules section):
961 Make yyerror and yylex static as usual.
963 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
965 Fix bug that mistakes braced code in a declaration in the rules section
966 to be a rule action. Mentioned at
967 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
968 * src/scan-gram.l: Move midrule action detection from the start of the
969 scanning of any braced code to...
970 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
971 action. For readability, use $2 and @2 rather than the equivalent
973 * tests/regression.at (Braced code in declaration in rules section):
974 New test to catch the error fixed by the above patch.
976 Work on code readability some.
977 * src/scan-code.l (current_rule): Get rid of this misleading and
978 redundant declaration: it's actually extern'ed in reader.h.
979 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
980 translate_action): Add a rule argument and use it instead of the global
982 (translate_rule_action): This already receives current_rule through an
983 argument, so pass it on to translate_action instead of assigning
984 current_rule to current_rule.
985 (translate_symbol_action, translate_code): Pass rule = NULL to
988 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
990 Rename %before-definitions to %start-header and %after-definitions to
991 %end-header. Don't use these declarations to separate pre-prologue
992 blocks from post-prologue blocks. Add new order-independent
993 declarations %before-header and %after-header as alternatives to the
994 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
995 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
996 * NEWS (2.3+): Update for these changes.
997 * data/glr.c (b4_before_definitions): Update to...

1005 prologue blocks with %*-header declarations.
1006 (Calc++ Parser): Likewise.
1007 (Bison Declaration Summary): Update names.
1008 (Bison Symbols): Update description.

1011 (PERCENT_BEFORE_DEFINITIONS): Update to...
1012 (PERCENT_START_HEADER): ... this.
1013 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
1014 (declaration): Update token names and m4 macro names.
1015 When parsing %end-header and %start-header, invoke translate_code
1016 before muscle_code_grow, and no longer set global booleans to remember
1017 whether these declarations have been seen.
1018 Parse new %after-header and %before-header.
1019 * src/reader.c (before_definitions, after_definitions): Remove.
1020 (prologue_augment): Accept a new bool argument to specify whether to
1021 augment the pre-prologue or post-prologue.
1022 * src/reader.h (before_definitions, after_definitions): Remove these
1024 (prologue_augment): Add new bool argument.
1025 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
1026 (PERCENT_END_HEADER): ... this.

1030 * tests/actions.at (Printers and Destructors): Update names.
1032 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
1034 Add comparison operators for C++ location classes. Discussed at
1035 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
1036 * data/c++.m4 (b4_define_location_comparison): New boolean %define
1037 declaration indicating whether filename_type has an operator==. If
1038 filename_type is `std::string', it defaults to `1', `0' otherwise.
1039 * data/location.cc: Iff b4_define_location_comparison is `1', add
1040 operator== and operator!= for class position and for class location.
1043 * src/scan-action.l: Remove unused file.
1044 * src/symtab.c (symbol_printer_set): Use printer_location not

1051 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
1053 Don't put the pre-prologue in the header file. For the yacc.c code
1054 file and the glr.c header and code files, move the pre-prologue before
1055 the token definitions. Add new %before-definitions and
1056 %after-definitions to declare code that will go in both the header file
1057 and code file. Discussed at
1058 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
1059 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
1061 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
1062 * NEWS (2.3+): Describe these changes.
1063 * data/glr.c (b4_pre_prologue): Move from within to before...

1065 Add new b4_before_definitions before b4_token_enums.
1066 Add new b4_after_definitions at the end.
1067 * data/glr.cc (b4_pre_prologue): Replace with...
1068 (b4_before_definitions): ... this in the header file.
1069 (b4_after_definitions): New near the end of the header file.
1070 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
1071 code file right before including the header file.
1072 (b4_before_definitions): New in the previous position of
1073 b4_pre_prologue in the header file.
1074 (b4_after_definitions): New near the end of the header file.
1075 * data/yacc.c: Clean up some m4 quoting especially in the header file.
1076 (b4_token_enums_defines): In the code file, move to right before
1077 YYSTYPE for consistency with the header file.
1078 (b4_before_definitions): New right before b4_token_enums_defines in
1079 both the header and code file.
1080 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
1081 header and code file.
1082 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
1083 of prologues for %union dependencies.
1084 (Bison Declaration Summary): In %defines description, mention the
1085 effect of %before-definitions and %after-definitions on the header
1087 (Calc++ Parser): Forward declare driver in a %before-definitions rather
1088 than in the pre-prologue so that make check succeeds.
1089 (Bison Symbols): Add entries for %before-definitions and
1091 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
1092 %before-definitions.
1093 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
1094 (declaration): Parse those declarations and append to
1095 b4_before_definitions and b4_after_definitions, respectively.
1096 * src/reader.c (before_definitions, after_definitions): New bools to
1097 track whether those declarations have been seen.
1098 (prologue_augment): Add to the post-prologue if %union,
1099 %before-definitions, or %after-definitions has been seen.
1100 * src/reader.h (before_definitions, after_definitions): New extern's.
1101 * src/scan-gram.l: Scan the new declarations.
1102 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
1103 prologue block in a %before-definitions or a %after-definitions based
1104 on whether the %union is declared.
1105 * tests/regression.at (Early token definitions with --yacc, Early token
1106 definitions without --yacc): Move tests for token definitions into the
1107 post-prologue since token names are no longer defined in the
1110 2006-06-20 Akim Demaille <akim@epita.fr>
1112 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
1113 (symbol_get): Use it.
1114 * src/parse-gram.y: Use it.
1116 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
1118 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
1119 build succeeds when configured with --enable-gcc-warnings.
1121 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1123 * src/parse-gram.y (char_name): New function.
1124 (CHAR, STRING, string_content): For %printer, properly escape.
1125 (ID): Prefer fputs to fprintf.
1126 (id): Reindent to be consistent with other rules.
1127 Properly quote char.
1129 The Translation Project changed its way of publishing translations
1130 to maintainers. I haven't received any responses to my request
1131 for supporting the old way, or for documenting the new way. I
1132 have modified 'bootstrap' to use screen scraping
1133 (in this case, HTML scraping). This is unreliable and inelegant,
1134 but I don't see any better way. Yuck.
1135 * bootstrap (TP_URL, WGET_COMMAND): New vars.
1136 (get_translations): New function, which uses HTML scraping to
1137 deduce locations of latest translations.
1138 Use this function to grab both bison and bison-runtime .po files.
1139 Don't bother priming the pump for the runtime-po domain any more,
1140 as it's now translated better than bison is.
1142 2006-06-19 Akim Demaille <akim@epita.fr>
1144 * src/scan-gram.l: No longer "parse" things after `%union' until
1145 `{'. Rather, return a single "%union" token.
1146 No longer make symbols: return strings, and leave the conversion
1147 to symbols to the parser.
1148 (SC_PRE_CODE, token_type): Remove.
1149 * src/parse-gram.y (%union): New field `character'.
1152 (ID, ID_COLON): Now that the scanner no longer makes them
1153 identifiers, adjust all uses to invoke symbol_get.
1154 (id_colon): New, wraps the conversion from string to symbol.
1155 (%union): Accept a possible union_name.
1156 (symbol): Now can be a char.
1157 * data/c.m4 (b4_union_name): Leave a default value.
1158 * data/glr.c, data/yacc.c: Use it.
1160 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
1162 For associating token numbers with token names for "yacc.c", don't use
1163 #define statements unless `--yacc' is specified; always use enum
1164 yytokentype. Most important discussions start at:
1165 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
1166 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
1168 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
1169 * NEWS (2.3+): Mention.
1170 * data/c.m4 (b4_yacc_if): New.
1171 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
1173 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
1174 on token name definitions.
1175 * src/getargs.c (usage): Capitalize `Yacc' in English.
1176 * src/output.c (prepare): Define b4_yacc_flag.
1177 * tests/regression.at (Early token definitions): Test that tokens names
1178 are defined before the pre-prologue not just before the post-prologue.
1179 Remove this test case and copy to...
1180 (Early token definitions with --yacc): ... this to test #define's.
1181 (Early token definitions without --yacc): ... and this to test enums.
1183 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
1185 * NEWS: Reword the post-2.3 change to not be so optimistic about
1186 removing the old "look-ahead" spelling.
1187 Update previous look-ahead/lookahead change reports.
1188 * REFERENCES: look-ahead -> lookahead (since that's
1189 what he actually wrote).
1190 * doc/refcard.tex: look ahead -> lookahead,
1191 look-ahead -> lookahead
1193 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
1195 For consistency, use `lookahead' instead of `look-ahead' or
1196 `look_ahead'. Discussed starting at
1197 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00049.html>
1199 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00017.html>.

1273 Bison without installing the yacc script.
1275 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
1277 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
1278 and yytext if they're already #define'd.

1310 Extract the parsing of user actions from the grammar scanner.
1311 As a consequence, the relation between the grammar scanner and

1377 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
1379 Between Bison releases, manually append `+' to the previous Bison
1380 release number, and use that as a signal to automatically print the
1381 ChangeLog's CVS Id keyword from --version. Discussed starting at
1382 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
1383 * ChangeLog: Add Id header.
1384 * configure.ac (AC_INIT): Append `+' to `2.3'.
1385 * src/.cvsignore: Add revision.c.
1386 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
1387 (BUILT_SOURCES): Add revision.c.
1388 (revision.c): New target rule. This file defines a new global variable
1389 named revision. It initializes it with either the Id from ChangeLog
1390 or, if VERSION doesn't contain `+', with the empty string.
1391 * src/getargs.c (version): Print the value of revision.
1392 * src/revision.h: Extern revision.
1394 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1396 * NEWS: Version 2.3.
1397 * configure.ac (AC_INIT): Likewise.
1399 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1401 * data/glr.c (YYRECOVERING): Define to be a function-like macro
1402 with no arguments, not as an object-like macro. This is for
1403 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
1404 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
1405 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
1408 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
1410 * src/getargs.c (usage): Back out yesterday's modification of the
1411 --help output so that we don't have to wait for translation before
1414 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
1416 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
1417 Problem reported by Akim Demaille.
1419 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
1421 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
1423 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
1425 * data/yacc.c (yy_reduce_print): Omit trailing white space in
1426 generated source code. Problem reported by Frans Englich in
1427 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
1429 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
1431 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
1432 shell, not within 'make', so that 'make' by an ordinary builder
1433 (using GNU make) does not worry about configuring gzip. This also
1434 works around a bug reported independently by Keith Thompson and by
1435 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
1436 stderr rather than stdout, messing up the build logs.
1438 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
1440 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
1441 to make sure that YYID will never be unused. This fixes a 'make
1442 maintainer-check' failure caused by the recent changes to the 'Trivial
1443 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
1445 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
1447 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
1449 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
1450 state before an empty RHS is always resolved here. Only the location
1451 of that state is guaranteed to be resolved, and that's enough. This
1452 fixes the remaining bug reported by Derek M. Jones in
1453 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
1454 * tests/glr-regression.at (Uninitialized location when reporting
1455 ambiguity): Test the above case.
1456 Also, the embedded comments in this test case claim it checks the case
1457 of an empty RHS that has inherited the initial location. However, the
1458 corresponding LHS was already resolved, so yyresolveLocations didn't
1459 actually have reason to modify it. Fix this by forcing
1460 nondeterministic operation at the beginning of the parse.
1462 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
1464 * data/c.m4 (b4_yy_symbol_print_generate):
1465 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
1466 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
1467 of the bugs reported today by Derek M Jones in
1468 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
1469 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
1470 defined to be a type name without parens or brackets.
1471 (Location Type): Similarly for YYLTYPE.
1472 * tests/regression.at (Trivial grammars): Put in a test for this
1473 bug that will be caught by 'make maintainer-check' (though not,
1474 alas, by 'make check' unless your compiler is picky).
1476 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
1478 * NEWS: Version 2.2.
1479 * configure.ac (AC_INIT): Likewise.
1481 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
1483 * data/glr.c (yyreportTree): Make room in yystates for the state
1484 preceding the RHS. This fixes the segmentation fault reported by Derek
1486 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
1487 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
1488 to the user. Reported for yyreportTree by Derek M. Jones later in the
1490 * THANKS: Add Derek M. Jones.
1491 Update my email address.
1492 Fix typo in Steve Murphy's name.
1494 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
1496 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
1497 checking against YYLAST that caused the parser to miss a potential
1498 alternative in its diagnostic.
1499 Problem reported by Maria Jose Moron Fernandez in
1500 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
1501 * data/lalr1.cc (yysyntax_error_): Likewise.
1502 * data/yacc.c (yysyntax_error): Likewise.
1503 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
1504 tokens, in case we run into an older C compiler.
1505 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
1506 Use them to check for the off-by-one error fixed above.
1508 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
1509 YYSIZE_T, not size_t.
1510 * tests/regression.at (Trivial grammars): New test, to catch
1511 the error fixed by the above patch.
1513 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
1515 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
1517 Reported by Steve Murphy.
1519 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
1521 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
1522 * data/glr.cc: b4_location_flag is now b4_locations_flag.
1524 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
1526 Implement --trace=m4.
1527 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
1528 * src/output.c (output_skeleton): When set, pass -dV to m4.
1530 Factor the handling of flags in m4.
1531 * src/output.c (prepare): Rename the muscle names debug, defines,
1532 error_verbose to debug_flag, defines_flag, error_verbose_flag.
1533 * data/c.m4: Adjust.
1534 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
1535 Use b4_define_flag_if to define other b4_FLAG_if macros.
1536 (b4_location_if): As a consequence, rename as...
1537 (b4_locations_if): this, for consistency.
1538 Adjust all the skeletons.
1540 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
1542 * etc/bench.pm: Shorten bench names.
1544 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
1546 * src/output.h, src/output.c (error_verbose): Move to...
1547 * src/getargs.h, src/getargs.c: here.
1549 Adjust dependencies.
1551 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
1553 * data/c.m4 (b4_copyright): Put the special exception for Bison
1554 skeletons here, so we don't have to put it in each skeleton. All
1555 uses changed. Suggested by Akim Demaille. Also, wrap the
1556 copyright notice, in case it is longer than 80 columns. Replace
1557 comma by newline after title.
1559 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
1561 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
1562 incompatibility, not a bug. Mention that it wasn't fixed as of
1565 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
1567 * examples/extexi: Enforce the precedence of concatenation over
1569 Reported by Tommy Nordgren.
1571 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
1573 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
1574 with the member "token".
1575 Reported by Martin Nylin.
1577 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
1579 * data/glr.c: Switch to Bison 2.2 special-exception language in
1580 the copyright notice. Use more-regular format for titles and
1582 * data/glr.cc: Likewise.
1583 * data/location.cc: Likewise.
1584 * data/yacc.cc: Likewise.
1585 * doc/bison.texinfo (Conditions): Document this.
1586 * NEWS: likewise. Upgrade version to 2.2.
1588 2006-04-27 Akim Demaille <akim@lrde.epita.fr>
1590 * data/glr.cc: Remove dead code.
1592 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
1594 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
1595 that variable and the line breaks the bootstrap. Problem reported
1596 by Juan M. Guerrero.
1598 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
1600 * doc/bison.texinfo (Multiple start-symbols): New.
1602 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
1604 * etc/README, etc/bench.pl: New.
1606 2006-04-03 Akim Demaille <akim@lrde.epita.fr>
1608 * src/scan-gram.l: Be robust to BRACED_CODE appearing before any
1610 Reported by Mickael Labau.
1611 * tests/input.at (Torturing the Scanner): Test it.
1613 2006-03-16 Paul Eggert <eggert@cs.ucla.edu>
1615 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
1616 Problem reported by Bob Rossi.
1618 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
1620 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
1621 and didn't really work.
1622 For the index, use @ifnotinfo, not @iftex.
1623 Minor cleanups of spacing and terminology.
1625 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
1627 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
1628 of AT_NAME_PREFIX when %name-prefix is not used.
1630 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
1632 Apply --prefix to C++ skeletons too: they change the namespace.
1633 The test suite already exercize these cases.
1634 * data/c++.m4 (b4_namespace): New.
1635 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
1636 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
1637 * data/yacc.c, data/glr.c: Remove a useless `[]'.
1638 * doc/bison.texinfo: Document it.
1639 (Option Cross Key): Use @multitable in all formats. It looks
1640 nicer, even in TeX outputs.
1641 (Rules): Use the same code whatever the output type is.
1642 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
1643 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
1644 * tests/calc.at: Use it, instead of hard coding `yy'.
1646 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
1648 * TODO: Remove dead items.
1650 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
1652 * doc/FAQ: Remove, merged into...
1653 * doc/bison.texinfo (FAQ): this.
1654 * doc/Makefile.am (EXTRA_DIST): Adjust.
1656 2006-03-10 Akim Demaille <akim@lrde.epita.fr>
1658 * data/c.m4 (b4_token_enum): Always define the enum of tokens,
1660 * data/lalrl1.cc, data/glr.cc (parser::token_type): New.
1661 * doc/bison.texinfo (Calc++ Scanner): Use it.
1663 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
1665 Fix two nits reported by twlevo, plus one more that I discovered.
1667 * src/assoc.h (assoc_to_string): Give a name to the arg, as
1668 this is the usual Bison style.
1669 * src/location.h (location_print): Likewise.
1671 * src/reader.h (token_name): Likewise.
1673 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
1675 Fix some nits reported by twlevo.
1676 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
1677 and "POSIX". Use more-modern syntax for URLs. Mention C++
1678 and ask for Java. Don't hardwire OS version numbers. Add
1680 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
1681 * src/conflicts.c (solved_conflicts_obstack): Now static.
1683 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
1685 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
1686 page. Say "you can use it" not "you may use it" as on the web page;
1687 we're describing capabilities not granting permission.
1689 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
1691 * data/glr.c (yyresolveLocations): Rename local variables to avoid
1692 shadowing warnings. Use usual patter for iterating through RHS.
1693 * tests/glr-regression.at
1694 (Uninitialized location when reporting ambiguity):
1695 Modify yylex so that it uses its argument, rather than trying
1696 to rely on ARGSUSED (which doesn't work for gcc with warnings).
1697 const char -> char const.
1699 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
1700 Don't use tabs inside commands; it messes up 'ps'.
1701 Problem reported by twlevo.
1703 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
1705 * tests/glr-regression.at (Uninitialized location when reporting
1706 ambiguity): New test case.
1707 * data/glr.c (yyresolveLocations): New function, which uses
1709 (yyresolveValue): Invoke yyresolveLocations before reporting an
1711 * doc/bison.texinfo (Default Action for Locations): Note
1712 YYLLOC_DEFAULT's usage for ambiguity locations.
1713 (GLR Semantic Actions): Cross-reference those notes.
1715 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
1717 * tests/glr-regression.at (Leaked semantic values when reporting
1718 ambiguity): Remove unnecessary union and type declarations.
1719 (Leaked lookahead after nondeterministic parse syntax error): New test
1721 * data/glr.c (yyparse): Check for zero stacks remaining before
1722 attempting to shift the lookahead so that you don't lose it.
1724 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
1726 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
1727 * tests/glr-regression.at (Leaked semantic values when reporting
1728 ambiguity): New test case.
1729 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
1730 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
1731 now unnecessary yystackp parameter.
1732 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
1733 destructors can be called.
1735 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
1736 in existing testcases.
1738 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
1740 Don't leak semantic values for parent RHS when a user action cuts the
1741 parser, and clean up related code a bit.
1742 * tests/glr-regression.at (Leaked merged semantic value if user action
1743 cuts parse): Rename to...
1744 (Leaked semantic values if user action cuts parse): ... this. Add check
1745 for leaked parent RHS values.
1746 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
1747 between an unresolved state (non-empty chain of semantic options) and
1748 an incomplete one (signaled by an empty chain).
1749 (yyresolveStates): Document the interface. Move all manipulation of a
1750 successfully or unsuccessfully resolved yyGLRState to...
1751 (yyresolveValue): ... here so that yyresolveValue always leaves a
1752 yyGLRState with consistent data and thus is easier to understand.
1753 Remove the yyvalp and yylocp parameters since they are always just
1754 taken from the yys parameter. When reporting a discarded merged value
1755 in debugging output, note that it is incompletely merged. Document the
1757 (yyresolveAction): If resolving any of the RHS states fails, destroy
1758 them all rather than leaking them. Thus, as long as user actions are
1759 written to clean up the RHS correctly, yyresolveAction always cleans up
1760 the RHS of a semantic option. Document the interface.
1762 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
1764 * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that
1765 led to a segmentation fault in GNU Pascal. Problem reported
1768 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
1770 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
1771 mid-rule action inside a nonterminal symbol in order to declare a
1772 destructor for its semantic value.
1774 2006-02-16 Paul Eggert <eggert@cs.ucla.edu>
1776 * data/yacc.c [(! defined yyoverflow || YYERROR_VERBOSE) && !
1777 YYSTACK_USE_ALLOCA && ! defined YYSTACK_ALLOC && defined
1778 __cplusplus && ! defined _STDLIB_H && !
1779 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||
1780 defined free))]: Include <stdlib.h> rather than rolling our own
1781 declarations of malloc and free, to avoid problems with
1782 incompatible declarations (using 'throw') C++'s stdlib.h. This
1783 should fix Debian bug 340012
1784 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=340012>,
1785 reported by Guillaume Melquiond.

1789 * NEWS: Clarify symbols versus types in unused-value warnings.
1791 * configure.ac (AC_INIT): Bump version number.
1793 2006-02-13 Paul Eggert <eggert@cs.ucla.edu>
1795 * NEWS: Version 2.1a.
1796 * tests/headers.at (AT_TEST_CPP_GUARD_H): Declare yyerror and yylex,
1797 since C99 requires this.
1799 2006-02-11 Paul Eggert <eggert@cs.ucla.edu>
1801 * m4/c-working.m4: New file.
1802 * configure.ac (BISON_TEST_FOR_WORKING_C_COMPILER): Use it.
1804 2006-02-10 Paul Eggert <eggert@cs.ucla.edu>
1806 * Makefile.maint: Merge from coreutils.
1808 2006-02-09 Paul Eggert <eggert@cs.ucla.edu>
1810 More portability fixes for problems summarized by Nelson H. F. Beebe.
1812 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Catch a
1813 configuration screwup "./configure CC=/opt/SUNWspro/bin/c89
1814 CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
1815 LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this
1816 messes up because C++ code is compiled in 32-bit mode but linked

1821 More portability fixes for problems summarized by Nelson H. F. Beebe.
1823 * doc/bison.texinfo (Calc++ Scanner): Work around a bug in flex
1824 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
1826 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
1827 nodist_PROGRAMS, since we don't need to actually compile the
1828 example if we're just doing a plain 'make'. This avoids bothering
1829 the installer unnecessarily about problems due to weird C++
1832 2006-02-06 Paul Eggert <eggert@cs.ucla.edu>
1834 More portability fixes for problems summarized by Nelson H. F. Beebe.
1836 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
1837 than #include "...", and compile with -I'.'. The old method was
1838 not portable, according to Posix and the C standard, and it does
1839 not work with Sun C 5.7, where previous #line directives affect
1840 the working directory used in later #include "..." directives.

1846 2006-02-02 Paul Eggert <eggert@cs.ucla.edu>
1848 More portability fixes for problems summarized by Nelson H. F. Beebe.
1850 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check that
1851 '#include <map>' works and that you can apply ++ to iterators.
1853 2006-02-01 Paul Eggert <eggert@cs.ucla.edu>
1855 Work around portability problems summarized by Nelson H. F. Beebe in
1856 <http://lists.gnu.org/archive/html/bug-bison/2005-09/msg00021.html>.
1858 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
1859 that '#include <string>' works.
1861 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
1862 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
1863 "warning: sorry: semantics of inline function static data `const
1864 unsigned char translate_table[262]' are wrong (you'll wind up with
1867 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
1868 or, xor to not_, and_, or_, and xor_, respectively. This works

1879 During deterministic GLR operation, user actions should be able to
1880 influence the parse by changing yychar. To make this easier to fix and
1881 to make glr.c easier to evolve in general, don't maintain yytoken in
1882 parallel with yychar; just compute yytoken when needed.
1883 * tests/glr-regression.at (Incorrect lookahead during deterministic
1884 GLR): Check that setting yychar in a user action has the intended
1886 * data/glr.c (yyGLRStack): Remove yytokenp member.
1887 (yyclearin): Don't set *yytokenp.
1888 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine

1909 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
1910 got from <http://bro-ids.org/download.html>. The bug is that
1911 when two actions appeared in succession, the second one was
1912 scanned before the first one was added to the grammar rule
1913 as a midrule action. Bison then output the incorrect warning
1914 "parse.y:905.17-906.36: warning: unused value: $3".

2176 in the yychar entry.
2177 In the yychar entry, remove mention of the local yychar case (pure
2178 parser) since this is irrelevant information when writing semantic
2179 actions and since it's already discussed in `Bison Symbols' where
2180 yychar is otherwise described as an external variable.
2181 In the yychar entry, don't call it the `current' look-ahead since it
2182 isn't when semantic actions are deferred.

2185 Add yylloc and yylval entries discussing look-ahead usage.
2186 (Look-Ahead Tokens): When discussing yychar, don't call it the

2212 from which the RHS is taken. Set the lookahead members of the new
2213 yySemanticOption according to the lookahead status for stack yyk.

2215 yyaddDeferredAction.
2216 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead

2227 (Incorrect lookahead during nondeterministic GLR): New test case.
2229 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>

2241 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
2243 * data/glr.c (yyresolveValue): When merging semantic options, if at
2244 least one user action succeeds but a later one cuts the parse, then
2245 destroy the semantic value before returning rather than leaking it.
2246 (yyresolveStates): If a user action cuts the parse and thus
2247 yyresolveValue fails, ignore the (unset) semantic value rather than
2248 corrupting the yyGLRState, and empty the semantic options list since
2249 the user actions should have called all necessary destructors.
2250 Simplify code with YYCHK.
2251 * tests/glr-regression.at (Corrupted semantic options if user action
2252 cuts parse): New test case.
2253 (Undesirable destructors if user action cuts parse): New test case.

2378 Use increment_rule_length rather than incrementing it by hand.
2379 (adjust_location, handle_syncline): Diagnose overflow.

2495 `if (YYID (N))' to pacify lint.
2497 2005-12-21 Akim Demaille <akim@epita.fr>

2520 * djgpp/config.sed: Replace every occurence of the file name
2521 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with

2551 sed out the final state number.
2553 Work around portability problem on Solaris 10: flex-generated
2554 files include <stdio.h> before <config.h>, which messes up
2555 because the latter defines __EXTENSIONS__. Address the problem
2556 by creating two new little files that include <config.h> first,
2557 then include the flex-generated files. Rewrite everyone else
2558 to include <config.h> first, as well.
2559 * lib/timevar.c: Always include "config.h".

2605 * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
2606 (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
2607 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
2609 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
2610 * data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
2611 Use YYID(0) rather than 0, for lint.
2612 (yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.

2634 * data/yacc.c: Say "parser skeleton" rather than "file", since
2635 it's no longer just a file.
2636 * data/glr.c: Grant a special exception for C GLR parsers, that
2637 reads like the already-existing exception for C LALR(1) parsers.

2639 * data/lalr1.cc: Likewise.

2807 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Pass
2809 * data/glr.c (YY_SYMBOL_PRINT, yydestroyGLRState): Adjust.
2810 * data/yacc.c (b4_Pure_if): Rename as...
2811 (b4_yacc_pure_if): this.
2812 (YY_SYMBOL_PRINT, yyparse): Adjust.
2813 * doc/bison.texinfo: Formatting changes.
2815 2005-10-21 Akim Demaille <akim@epita.fr>
2817 Finish the transition config -> build-aux.
2818 * configure.ac, Makefile.am: Use build-aux.
2819 * config/prev-version, config/announce-gen, config/Makefile.am:
2821 * build-aux/prev-version, build-aux/announce-gen,
2822 * build-aux/Makefile.am: here.
2824 2005-10-14 Akim Demaille <akim@epita.fr>
2826 * examples/calc++/test: Use set -x only when VERBOSE.
2828 2005-10-13 Paul Eggert <eggert@cs.ucla.edu>
2830 * NEWS: Bison now warns if it finds a stray `$' or `@' in an action.
2831 * src/scan-gram.l (<SC_BRACED_CODE>[$@]): Implement this.
2833 2005-10-13 Akim Demaille <akim@epita.fr>
2835 * src/scan-skel.l: Output the base name parts of the parser and
2837 * tests/output.at (AT_CHECK_OUTPUT): Support subdirectories, and
2839 Use this to exercise C++ outputs in subdirs.
2840 Reported by Oleg Smolsky.
2842 2005-10-12 Paul Eggert <eggert@cs.ucla.edu>
2844 * data/c.m4 (b4_c_function_def): Look at __C99_FUNC__, not at
2845 __STDC_VERSION__, as IBM cc 7.0 doesn't define the latter either.
2846 Problem reported by John P. Hartmann.
2847 * data/yacc.c (YYMODERN_C): Likewise. Don't define if the user has
2850 2005-10-12 Akim Demaille <akim@epita.fr>

2861 All uses replaced by 0 and 1.
2862 * src/scan-gram.l (gram_wrap): Redefine to avoid bug in flex 2.5.31
2863 that xlc complains about.
2864 * src/scan-skel.l (skel_wrap): Likewise.
2865 * data/c.m4 (b4_c_function_def): Look at __STDC_VERSION__ as well
2867 * data/yacc.c (YYMODERN_C): New macro, which also looks at
2868 __STDC_VERSION__. Use it everywhere instead of looking at
2869 __STDC__ and __cplusplus.
2871 2005-10-10 Akim Demaille <akim@epita.fr>
2873 * examples/calc++/test: Be quiet unless VERBOSE.

2878 Use YYUSE instead of casting to void.
2879 * data/glr.c (YYUSE): New macro.
2880 (yyuserMerge, yyreportAmbiguity, yyreportSyntaxError):
2881 Use it instead of rolling our own.
2882 (YYLLOC_DEFAULT, YYCHK, YYDPRINTF, YY_SYMBOL_PRINT, YY_REDUCE_PRINT):
2884 Use /*CONSTCOND*/ to suppress lint warnings.
2885 * data/lalr1.cc (YYLLOC_DEFAULT, YY_SYMBOL_PRINT, YY_REDUCE_PRINT):
2886 (YY_STACK_PRINT): Use 'false' not '0'.

2896 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
2898 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
2900 Undo the parts of the unlocked-I/O change that substituted
2901 putc or puts for printf. This might hurt performance a bit,
2902 but some people prefer the printf style.
2903 * data/c.m4 (yysymprint): Prefer printf to puts and putc.
2904 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.

2931 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
2933 Use unlocked I/O for a minor performance improvement on hosts like
2934 GNU/Linux and Solaris that support unlocked I/O. The basic idea
2935 is to use the gnlib unlocked-io module, and to prefer putc and
2936 puts to printf when either will work (since the latter doesn't
2937 come in an unlocked flavor).
2938 * bootstrap (gnulib_modules): Add unlocked-io.
2939 * data/c.m4 (yysymprint): Prefer puts and putc to printf.

2957 * src/system.h: Include unlocked-io.h rather than stdio.h.
2959 * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as

3002 2005-10-02 Juan Manuel Guerrero <juan.guerrero@gmx.de>
3004 * lib/subpipe.c: New function end_of_output_subpipe() added
3005 to allow support for non-posix systems. This is a no-op function
3008 * lib/subpipe.h: New function end_of_output_subpipe() added
3009 to allow support for non-posix systems. This is a no-op function
3012 * src/output.c (output_skeleton): Use end_of_output_subpipe() to
3013 handle the lack of pipe/fork functionality on non-posix systems.

3036 filename type is defined by the user.
3037 Forward declation location and position before the pre-prologue.

3050 * data/lalr1.cc (stack.hh, location.hh): Include earlier.
3051 (parser::token): New, from the moved free definition of tokens.
3052 (parser::semantic_value): Now a full definition instead of an
3053 indirection to YYSTYPE.
3054 (b4_post_prologue): No longer included in the header file, but
3055 in the implementation file.

3081 (yysyntax_error_): Takes the state number as argument.
3082 (yyreduce_print_): Use the argument yyrule, not the former
3085 2005-09-26 Paul Eggert <eggert@cs.ucla.edu>
3087 * bootstrap (gnulib_modules): Add verify.
3088 * lib/.cvsignore: Add verify.h.

3097 local variables whose names begin with 'yy'.
3098 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
3099 Trivial changes from Joel E. Denny.
3101 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
3103 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
3104 don't use alloca any more.
3106 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
3107 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
3108 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
3109 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
3110 to match yacc.c, to test more hosts.
3112 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
3114 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
3115 doesn't affect behavior.
3116 (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
3118 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
3119 This works a bit better with glibc, if user code has already included
3121 * doc/bison.texinfo (Bison Parser): Document that users can't
3122 arbitrarily use malloc and free for other purposes. Document
3123 that <alloca.h> and <malloc.h> might be included.
3124 (Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the
3125 user must declare alloca.

3137 (YYSTACK_ALLOC_MAXIMUM): Use it.
3138 (yysyntax_error): New function.
3139 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
3140 multiple syntax errors are reported, and alloca is being used.
3141 Instead, reallocate buffers twice as big each time, so that
3142 we waste at most half the allocated memory. Start with a small
3143 (128-byte) buffer that will suffice in most cases anyway.
3144 Use yysyntax_error to do most of the work.
3146 * doc/bison.texinfo (Error Reporting, Table of Symbols):
3147 yynerrs is the number of errors reported, not the number of
3150 * tests/glr-regression.at (Duplicated user destructor for lookahead):
3151 Mark it as expected to fail.
3152 Cast result of malloc; problem reported by twlevo@xs4all.nl.
3153 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
3154 Don't start user-code symbols with "yy", to avoid name space problems.
3156 2005-09-19 Akim Demaille <akim@epita.fr>
3158 Remove the traits, failed experiment.
3159 It never proved useful, and anyway because of the current
3160 definition, it was not possible to have several specialization of
3161 this traits, making it useless.
3162 * data/lalr1.cc (yy:traits): Remove.
3163 Inline its definitions in the parser class.
3165 2005-09-19 Akim Demaille <akim@epita.fr>

3187 * src/output.c (prepare): Likewise.
3188 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
3189 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
3190 is not defined. This is an awful hack, but it's enough for now.
3191 All callers changed.
3192 * tests/glr-regression-at (make_value): Args are const pointers now,
3193 to avoid GCC warning.
3194 (Duplicated user destructor for lookahead): New test. Currently
3195 skipped. It fails on my host but I'm not sure it'll always fail.
3197 2005-09-16 Akim Demaille <akim@epita.fr>
3199 * src/symtab.h (struct symbol): Declare the printer and destructor
3200 as const, to avoid accidental calls to free.

3211 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
3212 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
3215 2005-09-16 Akim Demaille <akim@epita.fr>
3217 * data/lalr1.cc (yylex_): Remove, inline its code.
3218 (yyreport_syntax_error_): Remove, replaced by...
3219 (yysyntax_error_): this which returns a string and leaves to the
3220 caller the call to the users' error function.
3221 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
3222 Move from members of the parser object...
3223 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
3224 to local variables of the parse function.
3226 2005-09-16 Akim Demaille <akim@epita.fr>
3228 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
3229 since it's in Bison's name space.
3231 2005-09-15 Paul Eggert <eggert@cs.ucla.edu>
3233 * data/glr.c (yyresolveValue): Add default case to pacify

3240 * data/lalr1.cc: Revert part of previous change, as it's incompatible.
3241 (b4_filename_type): Renamed back from b4_file_name_type. All uses
3243 (class position): file_name -> filename (reverting). All uses changed.
3245 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
3247 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
3248 do anything if $@ exists. This reverts part of the 2005-07-07
3251 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
3253 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
3254 contains obsolete information and isn't worth distributing as a
3255 separate file anyway.
3256 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
3257 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
3258 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
3259 (yyparse): Abort if user code uses longjmp to throw an unexpected
3262 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
3264 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
3265 Suggested by twlevo@xs4all.nl.
3267 * data/glr.c (YYCHK1): Do not assume YYE is in range.
3268 This avoids a diagnostic from gcc -Wswitch-enum.
3269 Problem reported by twlevo@xs4all.nl.
3271 * doc/bison.texinfo: Don't use "filename", as per GNU coding
3272 standards. Use "file name" or "file" or "name", depending on
3274 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
3275 not to hack/foo.tab.c.
3276 (Calc++ Top Level): 2nd arg of main is not const.
3277 * data/glr.c: b4_filename -> b4_file_name.
3278 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.
3280 (class position): filename -> file_name. All uses changed.
3281 * data/yacc.c: b4_filename -> b4_file_name.
3282 * lib/bitset.h: filename -> file_name in local vars.
3283 * lib/bitset_stats.c: Likewise.
3284 * src/files.c: Likewise.
3285 * src/scan-skel.l ("@output ".*\n): Likewise.
3286 * src/files.c (file_name_split): Renamed from filename_split.
3287 * src/muscle_tab.c (muscle_init): Output b4_file_name, not b4_filename.
3289 2005-09-08 Paul Eggert <eggert@cs.ucla.edu>
3291 * lib/.cvsignore: Add pipe-safer.c, stdio--.h, unistd--.h,
3292 to accommodate latest gnulib.
3294 * tests/glr-regression.at (Duplicate representation of merged trees):
3295 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
3297 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
3300 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
3302 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
3303 All uses changed. Invoke user destructor after an error during a
3304 split parse (trivial change from Joel E. Denny).
3306 * tests/glr-regression.at
3307 (User destructor after an error during a split parse): New test case.
3308 Problem reported by Joel E. Denny in:
3309 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
3311 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
3313 * README-cvs: Give URLs for recommended tools.
3314 Mention Gzip version problem, and bootstrapping issues.
3315 Remove troubleshooting section, as it's somewhat obsolete.
3317 * bootstrap (no_cache): New var, to accommodate different wget
3318 variants. Use it instead of '-C off'. Problem reported by
3321 * data/glr.c (yydestroyStackItem): New function.
3322 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
3323 debugging information. Problem reported by Joel E. Denny.
3325 2005-08-25 Akim Demaille <akim@epita.fr>
3327 * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.
3329 2005-08-24 Paul Eggert <eggert@cs.ucla.edu>

3333 * tests/glr-regression.at
3334 (User destructor for unresolved GLR semantic value): New test case.
3335 Problem reported by Joel E. Denny in:
3336 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
3338 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
3340 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
3342 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
3343 lib-prefix.m4, po.m4.
3345 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
3346 in yydestruct diagnostic, since it might not be an error.
3347 Problem reported by Joel Denny near end of
3348 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
3349 * data/lalr1.cc (yyerturn): Likewise.
3350 * data/yacc.c (yyreturn): Likewise.
3351 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
3353 * src/files.c: Remove obsolete FIXME comment.
3355 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
3356 with the other templates, and to fix bogus run-on messages such
3357 as the one reported at the end of
3358 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
3359 All callers changed to avoid the newline.
3360 (yyprocessOneStack): Output two lines rather than one, to accommodate
3361 the above change. This changes the debug output format slightly.
3363 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
3364 reported by Joel E. Denny in
3365 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
3367 * tests/glr-regression.at (Duplicate representation of merged trees):
3368 New test, from Joel E. Denny in:
3369 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
3370 * THANKS: Add Joel E. Denny.
3372 * configure.ac (AC_INIT): Bump to 2.0c.
3374 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
3376 * NEWS: Version 2.0b.
3378 * Makefile.am (SUBDIRS): Put examples before tests, so that
3379 "make check" doesn't finish with "All 1 tests passed".
3381 * tests/regression.at (Token definitions): Don't rely on
3382 AT_PARSER_CHECK for data that contains backslashes. It currently
3383 uses 'echo', and 'echo' isn't portable if its argument contains
3384 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
3385 that the byte '\0xff' is not printable in the C locale; it is,
3386 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
3387 not printable, so use '\0x81' to test.
3389 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
3390 version of GCC, since the macro is used with non-GCC compilers.
3392 Fix core dump reported by Pablo De Napoli in
3393 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
3394 * tests/regression.at (Invalid inputs with {}): New test.
3395 * src/parse-gram.y (token_name): Translate type before using
3398 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
3399 the user's name space. All uses changed to __attribute__
3401 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
3402 Add __attribute__ ((__noreturn__)).
3404 * etc/clcommit: Remove. We weren't using it, and it failed
3405 "make maintainer-distcheck".
3406 * Makefile.maint: Merge from coreutils.
3407 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
3408 (syntax-check-rules): Change list of rules as described below.
3409 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
3410 (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):
3411 (sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope):
3412 (sc_trailing_space): New rules.

3415 (sc_space_tab, sc_error_exit_success, sc_changelog):
3416 (sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
3417 (makefile-check, po-check, author_mark_check):
3418 (makefile_path_separator_check, copyright-check):
3419 Use grep -n, to make it easier to find violations.
3420 Use CVS_LIST and CVS_LIST_EXCEPT.
3421 (header_regexp, h_re): Remove.
3423 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
3424 (my-distcheck): Use more-modern GCC flags.
3425 (signatures, %.asc): Remove.
3426 (rel-files, announcement): Remove signatures.
3427 Restore old updating code, even though we don't use it, so
3428 that we're the same as coreutils.
3429 (alpha, beta, major): Depend on news-date-check.
3430 Make the upload commands.
3432 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
3433 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
3434 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
3435 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.

3437 * src/parse-gram.y, src/system.h, src/tables.c, src/vcg.c: Likewise.
3438 * src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise.
3439 * tests/sets.at: Likewise.
3441 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
3442 we comment out the Autoconf version number.
3443 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
3444 it's error-prone and "make maintainer-distcheck" rejects it.
3446 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
3447 Indent calls to "error" to pacify "make maintainer-distcheck",
3448 when the calls are not intended to be translated.
3449 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
3451 * src/Makefile.am (DEFS): Use +=, to pacify
3452 "make maintainer-distcheck".
3453 (bison_SOURCES): Add scan-skel.h.
3454 (sc_tight_scope): New rule, from coreutils.
3456 * src/files.c (src_extension, header_extension):
3457 Now static, not extern.
3458 * src/getargs.c (short_options): Likewise.
3459 * src/muscle_tab.c (muscle_table): Likewise.
3460 * src/parse-gram.y (current_class, current_type, current_prec):
3462 * src/reader.c (grammar_end, previous_rule_end): Likewise.
3463 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
3464 * src/main.c (main): Cast bindtextdomain and textdomain calls to
3465 void, to avoid warning when NLS is disabled.
3466 * src/output.c: Include scan-skel.h.
3467 (scan_skel): Remove decl, since scan-skel.h does this.
3469 Indent calls to "error" to pacify "make maintainer-distcheck".
3470 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
3471 * src/reader.h (gram_end, gram_lineno): New decls to pacify
3472 "make maintainer-distcheck".
3473 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
3474 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
3475 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
3476 (skel_lex_destroy, scan_skel): Move these decls to...
3477 * src/scan-skel.h: New file.
3478 * src/uniqstr.c (uniqstr_assert):
3479 Indent calls to "error" to pacify "make maintainer-distcheck".
3481 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
3484 * tests/torture.at: Revamp to avoid misuse of atoi that
3485 "make maintainer-distcheck" complained about.
3487 * examples/extexi (message): Don't print a message more than once,
3488 and omit line-number decoration that makes Emacs compile think
3489 that informative messages are worth worrying about.
3491 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
3493 * configure.ac: Update version number.
3495 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
3497 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
3498 autogenerated by the maintainer.
3499 * examples/calc++/.cvsignore: Add *.yy.
3501 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
3502 * lib/bitset_stats.c (bitset_stats_init): Likewise.
3503 * lib/bitsetv.c (bitsetv_alloc): Likewise.
3505 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
3507 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
3508 from maintainer-distcheck about casting the argument of 'free'.
3510 * NEWS: Mention recent yytname changes.
3511 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
3513 * bootstrap: For translations that have not yet been upgraded to
3514 the new runtime-po domain, prime the pump by extracting the
3515 relevant strings from the obsolete translations. This code can be
3516 removed once the bison-runtime domain has been translated by each
3519 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
3520 now that token names are already quoted.
3522 Fix problem reported by Anthony Heading.
3523 * data/glr.c (YYTOKEN_TABLE): New macro.
3524 (yytname): Define if YYTOKEN_TABLE.
3525 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
3526 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
3527 (YYERROR_VERBOSE): Define the same way the other skeletons do.
3528 * src/output.c (prepare_symbols): Output token_table_flag.
3530 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
3532 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
3533 again if the first call fails.
3535 * data/glr.c (yytnamerr): New function.
3536 (yyreportSyntaxError): Use it to dequote most string literals.
3537 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
3538 with other skeletons. All uses changed.
3539 (yytnameerr_): New function.
3540 (yyreport_syntax_error): Use it to dequote most string literals.
3541 * data/yacc.c (yytnamerr): New function.
3542 (yyerrlab): Use it to decode most string literals.
3543 * doc/bison.texinfo (Decl Summary, Calling Convention):
3544 Clarify quoting convention of yytname.
3545 * src/output.c (prepare_symbols): Quote all names. This undoes
3546 the 2005-04-17 change, which is now accomplished (mostly) via
3547 changes in the parsers as described above.
3548 * tests/regression.at (Token definitions, Web2c Actions):
3549 Undo most 2005-04-17 change here, too.
3551 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
3553 Fix more problems reported by twlevo@xs4all.nl.
3554 * tests/cxx-type.at: Don't pipe output of ./types through sed to
3555 remove trailing spaces. This loses the exit status of ./types,
3556 and isn't needed since ./types shouldn't be emitting trailing
3558 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
3559 as the stack isn't valid in that case.
3561 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
3562 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
3563 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
3564 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
3566 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
3567 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
3568 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
3571 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
3572 overly-picky compilers that reject 'char *foo = "bar";'.
3574 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
3575 to FILE * parameter, not to stderr. This fixes a typo introduced
3576 in the 2005-07-12 change.
3578 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
3579 warnings from GCC 4.
3581 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
3582 (yyglrShiftDefer, yysplitStack):
3583 Remove unused parameters b4_pure_formals. All uses changed.
3584 (yyglrShift): Remove unused parameters b4_user_formals.
3586 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
3588 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
3590 Destructor cleanups and regularization among the three skeletons.
3591 * NEWS: Document the behavior changes.
3592 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
3593 stack before failing, as the cleanup code will do it for us now.
3594 * data/lalr1.cc (yyerrlab): Likewise.
3595 * data/glr.c (yyparse): Pop everything off the stack before
3596 freeing it, so that destructors get called properly.
3597 * data/lalr1.cc (yyreturn): Likewise.
3598 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
3599 This is more consistent.
3600 * doc/bison.texinfo (Destructor Decl): Mention more reasons
3601 why destructors might be called. 1.875 -> 2.1.
3602 (Destructor Decl, Decl Summary, Table of Symbols):
3603 Some English-language cleanups for %destructor.
3604 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
3605 Add output line for destructor of start symbol.
3606 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
3607 because of that same extra output line.
3609 * NEWS: Document minor wording changes in diagnostics of
3610 Bison-generated parsers.
3611 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
3612 Remove unused formals. All uses changed.
3613 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
3614 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
3615 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
3616 Rename yyoverflowab to yyexhaustedlab.
3617 When memory exhaustion occurs during syntax-error reporting,
3618 report it separately rather than in a single diagnostic; this
3620 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
3621 (Memory Exhausted): Renamed from Parser Stack Overflow.
3622 Revamp wording slightly to prefer "memory exhaustion".
3623 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
3625 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
3627 Add i18n support to the GLR skeleton. Partially fix the C++
3628 skeleton; a C++ expert needs to finish this. Remove debugging
3629 msgids; there's little point to having them translated, since they
3630 can be understood only by someone who can read the
3631 (English-language) source code.
3633 Generate runtime-po/bison-runtime.pot automatically, so that we
3634 don't have to worry about garbage getting in that file. We'll
3635 make sure after the next official release that old msgids don't
3637 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
3639 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
3641 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
3642 Fix typos in explanations of the runtime file.
3643 * bootstrap: Change gettext keyword from YYI18N to YY_.
3644 Use standard Makefile.in.in in runtime-po, since we'll arrange
3645 for backward-compatible bison-runtime.po files in a different way.
3646 * data/glr.c (YY_): New macro, from yacc.c.
3647 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
3648 Translate messages intended for users.
3649 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
3650 the wording in the other skeletons. We don't know that the memory
3652 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
3653 Use same method that yacc.c uses.
3654 Don't translate debugging messages.
3655 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
3656 it doesn't work (yet), and requires C++ expertise to fix.
3657 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
3658 Move defn to a more logical place, to be consistent with other
3660 Don't translate debugging messages.
3661 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
3662 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
3663 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
3664 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
3666 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
3667 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
3669 * tests/glr-regression.at (Badly Collapsed GLR States):
3671 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
3672 yylex should return 0 at EOF rather than aborting.
3674 Improve tests for stack overflow in GLR parser.
3675 Problem reported by twlevo@xs4all.nl.
3676 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
3678 (yyStackOverflow): Just longjmp, but with value 2 so that caller
3679 can handle the problem.
3680 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
3681 (yyparse): New local variable yyresult to record the result.
3682 Use result of setjmp to set it, rather than storing itinto
3684 (yyDone): Remove label.
3685 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
3686 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
3687 if YYABORT is used).
3688 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
3689 yyparse status; put status > 1 into diagnostic.
3690 Check that status==2 works.
3691 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
3692 Use exit status 3 for failure to open (which shouldn't happen).
3694 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
3696 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
3697 1 on syntax error; just let yyparse do its thing.
3698 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
3699 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
3700 (Exploding the Stack Size with Alloca):
3701 (Exploding the Stack Size with Malloc):
3702 Expect exit status 2, not 1, since the parser is supposed to blow
3703 its stack. Problem reported by twlevo@xs4all.nl.
3705 * data/glr.c (yyparse): Don't assume that the initial calls
3706 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
3707 Print a stack-overflow message and fail instead.
3708 Initialize the line-number information before creating the stack,
3709 so that the stack-overflow message can report line zero safely.
3711 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
3713 Fix problems reported by twlevo@xs4all.nl.
3714 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
3715 (yyuserMerge): Provide a default case if b4_mergers is empty.
3716 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
3717 * tests/glr-regression.at
3718 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
3719 Add casts to pacify C++ compilers.
3720 * tests/glr-regression.at (Improper merging of GLR delayed action
3721 sets): Declare yylex before using it.
3722 * tests/Makefile.am (maintainer-check-g++): Fix a stray
3723 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
3724 test for valgrind; valgrind is independent of g++.
3725 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
3726 for compatibility with POSIX 1003.1-2001 (if running coreutils).
3727 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
3728 Use a destructor, so that we can expand the stack. Change
3729 YYSTYPE to char * so that we can free it. Cast result of malloc.
3731 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
3733 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
3734 a valgrind failure. Problem reported by twlevo@xs4all.nl.
3736 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
3738 * PACKAGING: New file, suggested by Bruno Haible and taken from
3739 similar wording in gettext's PACKAGING file.
3740 * NEWS: Mention PACKAGING.
3741 * Makefile.am (EXTRA_DIST): Add PACKAGING.
3743 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
3745 * NEWS: Document recent i18n improvements.
3746 * bootstrap: Get runtime translations into runtime-po.
3747 Create runtime-po files automatically, if possible.
3748 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
3749 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
3750 does not infringe on the user's name space.
3751 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
3752 * doc/bison.texinfo (Internationalization): Revamp the English
3753 and Texinfo syntax a bit, to try to make it clearer.
3754 (Bison Options, Option Cross Key): Mention --print-localedir.
3755 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
3756 YYENABLE_NLS. Quote a bit more.
3757 * runtime-po/.cvsignore: New file.
3758 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
3759 * runtime-po/Rules-quot: Remove; now created by bootstrap.
3760 * runtime-po/quot.sed: Likewise.
3761 * runtime-po/boldquot.sed: Likewise.
3762 * runtime-po/en@quot.header: Likewise.
3763 * runtime-po/en@boldquot.header: Likewise.
3764 * runtime-po/insert-header.sin: Likewise.
3765 * runtime-po/remove-potcdate.sin: Likewise.
3766 * runtime-po/Makevars: Likewise.
3767 * runtime-po/LINGUAS: Likewise.
3768 * runtime-po/de.po: Likewise; we will rely on the translation project
3769 to maintain this, so "bootstrap" should get it.
3770 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
3772 * src/main.c (main): Bind the bison-runtime domain, too.
3774 2005-07-12 Bruno Haible <bruno@clisp.org>
3776 * data/yacc.c: Include <libintl.h> when NLS is enabled.
3777 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
3778 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
3779 * runtime-po: New directory.
3780 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
3781 $(DOMAIN).pot-update rule, so that old messages are never dropped.
3782 * runtime-po/Rules-quot: New file, copied from po/.
3783 * runtime-po/quot.sed: Likewise.
3784 * runtime-po/boldquot.sed: Likewise.
3785 * runtime-po/en@quot.header: Likewise.
3786 * runtime-po/en@boldquot.header: Likewise.

3793 * runtime-po/de.po: New file.
3794 * m4/bison.m4: New file.
3795 * Makefile.am (SUBDIRS): Add runtime-po.
3796 (aclocaldir, aclocal_DATA): New variables.
3797 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
3799 * src/getargs.c (usage): Document --print-localedir option.
3800 (PRINT_LOCALEDIR_OPTION): New enum item.
3801 (long_options): Add --print-localedir option.
3802 (getargs): Handle --print-localedir option.
3803 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
3804 (Internationalization): New section.
3806 2005-07-12 Akim Demaille <akim@epita.fr>
3808 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
3809 for consistency with the rest of the code.
3810 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
3813 2005-07-12 Akim Demaille <akim@epita.fr>
3815 * src/parse-gram.y: Use %printer instead of YYPRINT.
3817 2005-07-12 Akim Demaille <akim@epita.fr>
3819 * src/symtab.h, src/symtab.c (symbol_print): New.
3820 * src/symlist.h, src/symlist.c (symbol_list_print): New.

3823 2005-07-12 Akim Demaille <akim@epita.fr>
3825 * data/glr.c (b4_syncline): Fix (swap) the definitions of
3826 b4_at_dollar and b4_dollar_dollar.
3828 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
3830 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
3831 and Pennello's paper.
3833 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
3835 * data/yacc.c (yyparse): Undo previous patch. Instead,
3836 set yylsp[0] and yyvsp[0] only if the initial action
3837 sets yylloc and yylval, respectively.
3839 * data/yacc.c (yyparse): In the initial action, set
3840 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
3841 This avoids the use of undefined variables if the initial
3842 action does not set yylloc and/or yylval.
3844 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
3846 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
3847 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
3848 Remove from CVS. These files are automatically generated.
3849 * examples/extexi: Clarify that this file is now part of Bison,
3850 not GNU M4, and that it works with any POSIX-compatible Awk.
3851 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
3852 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
3853 so that we also get calc++-parser.yy. Geneate it.
3854 Use $(AWK), not gawk, since any conforming Awk will do.
3855 Put comment before action, since older 'make' can't handle comment
3857 $(BUILT_SOURCES): List all built sources, not just some of them.
3858 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
3859 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
3860 $($(calc_sources_generated)): Remove unnecessary test for existence
3861 of target. (This had a shell syntax error anyway; a stray "x".)
3862 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
3864 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
3866 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
3867 implied by the other modules.
3869 2005-07-06 Akim Demaille <akim@epita.fr>
3871 Bind examples/calc++ to the package.

3875 * examples/calc++/compile: Remove.
3876 * examples/Makefile.am: New.
3877 * configure.ac, Makefile.am: Adjust.
3878 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
3880 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
3882 * data/glr.c (yyFail): Drastically simplify; since the format argument
3883 never had any % directives, we can simply pass it to yyerror.
3884 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
3885 be modified later, as that is the usual style in glr.c.
3886 Problems reported by Paul Hilfinger.
3888 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
3889 and size overflow errors.
3890 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
3891 in case the user prolog sets feature-test macros like _GNU_SOURCE.
3892 (YYSIZEMAX): New macro.
3893 (yystpcpy): New function, taken from yacc.c.
3894 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
3895 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
3896 so that we don't have to maintain their signatures.
3897 (yyFail): Check for buffer overflow, by using vsnprintf rather
3898 than vsprintf. Allocate a bigger buffer if possible.
3899 Report an error if buffer allocation fails.
3900 (yyStackOverflow): New function.
3901 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
3902 the initialization was successful. It might fail if storage was
3904 (yyexpandGLRStack): Add more checks for storage allocation failure.
3905 Use yyStackOverflow to report failures.
3906 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
3907 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
3908 Don't assume stack number fits in int.
3909 (yysplitStack): Check for storage allocation failure.
3910 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
3911 can print diagnostics on storage allocation failure. All callers
3913 (yyresolveValue): Use yybool for boolean.
3914 (yyreportSyntaxError): Check for size-calculation overflow.
3915 This code is taken from yacc.c.
3916 (yyparse): Check for storage allocation errors when allocating
3919 2005-07-05 Akim Demaille <akim@epita.fr>
3921 Extract calc++ from the documentation.
3922 * doc/bison.texinfo (Calc++): Add the extraction marks.
3923 * examples/extexi: New, from the aborted GNU Programming 2E.
3924 Separate the different paragraph of a file with empty lines.
3925 * examples/Makefile: Use it to extract the whole calc++ example.
3927 2005-06-24 Akim Demaille <akim@epita.fr>
3929 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
3932 2005-06-22 Akim Demaille <akim@epita.fr>
3934 * doc/bison.texinfo (C++ Language Interface): First stab.
3935 (C++ Parsers): Remove.
3937 2005-06-22 Akim Demaille <akim@epita.fr>
3939 * data/lalr1.cc (yylex_): Honor %lex-param.
3941 2005-06-22 Akim Demaille <akim@epita.fr>
3943 Start a set of simple examples.

3946 * examples/calc++/calc++-parser.yy,
3947 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
3948 * examples/calc++/compile, examples/calc++/test: New.
3950 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
3952 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
3953 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
3954 which stems from the 2005-05-27 patch.
3956 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
3958 * data/glr.c: Modify treatment of unused parameters to permit use
3959 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
3961 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
3963 Fix infringement on user name space reported by Janos Zoltan Szabo.
3964 * data/yacc.c (yyparse): strlen -> yystrlen.
3966 2005-05-30 Akim Demaille <akim@epita.fr>
3968 * data/lalr1.cc (_): New.
3969 Translate the various messages.
3971 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
3973 Fix infringement on user name space reported by Bruno Haible.
3974 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
3975 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
3976 the user's name space.
3977 (alloca): Include <stdlib.h> to get it, if it's not built in.
3978 (YYMALLOC, YYFREE): Define only if needed.
3979 (malloc, free): Declare, but only if needed, as this infringes on
3980 the user name space.
3982 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
3984 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
3985 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
3987 * lib/ebitset.c (min, max): Undef before defining.
3988 * lib/vbitset.c (min, max): Likewise.
3989 * lib/subpipe.c (create_subpipe): Save local variables in case
3990 vfork clobbers them.
3992 2005-05-24 Bruno Haible <bruno@clisp.org>
3994 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
3995 error message syntax used by gcc-4.0.
3997 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
3999 * README: Mention m4 1.4.3. Remove obsolete advice about
4000 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
4002 * bootstrap: Remove workaround for problem I encountered with
4003 gettext 0.14.1; it seems to be fixed now.
4005 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
4007 * NEWS: Version 2.0a.
4009 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
4010 the previous change.
4012 Various maintainer cleanups.
4013 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
4014 conftest*, for benefit of CVS commands run at the same time as
4015 "configure". Add build-aux, since "bootstrap" now creates it and
4017 * Makefile.cfg (move_if_change): Remove.
4018 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
4019 (ftp-gnu, www-gnu, move_if_change, local_updates, update):

4026 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
4027 this is now the recommended name.
4028 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
4029 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
4030 ylwrap. These files now go into build-aux.
4031 * config/move-if-change: Remove.
4032 * config/prev-version.txt: Bump from 1.75 to 2.0.
4034 * bootstrap: Add stdio-safer, unistd-safer modules.

4038 fopen-safer.c, stdio-safer.h, unistd-safer.h.
4039 * lib/subpipe.c: Include "unistd-safer.h".
4040 (create_subpipe): Make sure all the newly-created
4041 file descriptors are > 2, so that diagnostics don't
4042 get sent down them (which might cause Bison to hang, in theory).
4043 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
4044 * src/files.c (xfopen): Use fopen_safer, not fopen.
4046 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
4047 yesterday's yacc.c fix.
4049 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>

4053 Fix a destructor bug reported by Wolfgang Spraul in
4054 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
4055 * data/yacc.c (yyabortlab): Don't call destructor, and
4056 don't set yychar to EMPTY.
4057 (yyoverflowlab): Don't call destructor.
4058 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
4059 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
4060 since we no longer output the message "discarding lookahead token
4063 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
4065 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
4066 fix a small glitch in debugging output.
4067 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
4068 after YY_SYMBOL_PRINT where needed.
4070 (struct yyGLRState): Add some comments.
4071 (struct yySemanticOption): Add some comments.
4072 (union yyGLRStackItem): Add comment.

4119 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
4121 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
4122 Problem reported by Ralf Menzel.
4124 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
4126 * tests/actions.at: Test that stack overflow invokes destructors.
4127 From Marcus Holland-Moritz.
4128 * data/yacc.c (yyerrlab): Move the code that destroys the stack
4130 (yyreturn): to here. That way, destructors are called properly
4131 even if the stack overflows, or the user calls YYACCEPT or
4132 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
4133 (yyoverflowlab): Destroy the lookahead.
4135 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
4137 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
4139 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
4141 * NEWS: Bison-generated C parsers no longer quote literal strings
4142 associated with tokens.
4143 * src/output.c (prepare_symbols): Don't escape strings,
4144 since users don't want to see C escapes.
4145 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
4147 * tests/input.at (Torturing the Scanner): Likewise.
4148 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
4150 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
4152 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
4153 the data size is known to be too small and we can't increase it.
4154 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
4156 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
4158 * src/parse-gram.y: Include quotearg.h.
4159 (string_as_id): Quote $1 before using it as a key, since the
4160 lexer no longer quotes it for us.
4161 (string_content): Don't strip quotes, since lexer no longer
4163 * src/scan-gram.l: Include quotearg.h.
4165 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
4166 a key, since the rest of the lexer doesn't quote it.
4167 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
4168 * tests/regression.at (Token definitions): Check for backslashes
4171 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
4172 (YYSIZE_T): Define to unsigned long int when using an older compiler.
4173 (yyparse): Revamp code to generate long syntax error message, to
4174 make it easier to translate, and to avoid problems with arithmetic
4175 overflow. Change "virtual memory" to "memory" in diagnostic, since
4176 we don't know whether the memory is virtual.
4178 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
4180 * NEWS: Bison-generated C parsers now use the _ macro to
4182 * data/yacc.c (_) [!defined _]: New macro.
4183 All English strings wrapped inside this macro.
4184 * doc/bison.texinfo (Bison Parser): Document _.
4185 * po/POTFILES.in: Include src/parse-gram.c, since it now
4186 includes translateable strings that parse-gram.y doesn't.
4188 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
4190 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
4191 reverting the 2004-10-11 change to this function.
4192 (symbol_check_alias_consistency): Don't call symbol_type_set
4193 if the type name is already correct.
4194 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
4196 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
4198 * tests/regression.at (Token definitions): Don't use a token named
4199 c, as that generates a "#define c ..." that runs afoul of buggy
4200 stdlib.h that uses the identifier c as a member of struct
4201 drand48_data. Problem reported by Horst Wente.
4203 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
4205 * bootstrap: Change translation URL from
4206 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
4207 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
4208 redirection glitches. Problem reported by twlevo@xs4all.nl.
4210 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
4212 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
4213 after operands; POSIX says this isn't portable for the c99 command.
4215 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
4217 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
4218 immediately if a data overrun has occurred; this may help us track
4219 down what may be a spurious failure on MacOS.
4221 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
4223 Respond to problems reported by twlevo@xs4all.nl.
4225 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
4227 * src/vcg.h: Comment fix.
4228 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
4229 (G_CMAX): Change to -1 instead of INT_MAX.
4231 * data/yacc.c (yyparse): Omit spaces before #line.
4233 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
4235 * src/tables.c (state_number_to_vector_number): Put it inside an
4236 "#if 0", since it's not currently used. Problem reported by
4239 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
4241 * src/output.c (escaped_output): Renamed from
4242 escaped_file_name_output, since we now use it for symbol tags as
4243 well. All uses changed.
4244 (symbol_destructors_output, symbol_printers_output):
4245 Escape symbol tags too.
4246 Problem reported by Matyas Forstner in
4247 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
4249 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
4251 * src/output.c (user_actions_output, token_definitions_output,
4252 symbol_destructors_output, symbol_printers_output): Likewise.
4253 * src/reader.c (prologue_augment): Likewise.
4254 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
4256 * src/vcg.c (output_edge): Don't quote linestyle arg.
4257 Problem reported by twlevo@xs4all.nl.
4259 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
4261 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
4262 example, reported by Derek M Jones. Also, make the example even
4263 more outrageous, to better illustrate how bad the problem is.
4265 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
4267 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
4268 putsym. Typo reported by Sebastian Piping.
4270 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4272 * doc/bison.texinfo (Language and Grammar): some -> same
4273 (Epilogue): int he -> in the
4274 Typos reported by Sebastian Piping via Justin Pence.
4276 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
4278 * tests/glr-regression.at (Improper handling of embedded actions
4279 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
4280 embedded actions and $-N in GLR parsers", work around an Autoconf bug
4281 with dollar signs in test names.
4282 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
4283 for a similar reason.
4285 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
4287 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
4288 wants to redefine G_VIEW.
4290 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
4292 * src/vcg.c (get_view_str): Remove case for normal_view.
4293 Problem reported by twlevo@xs4all.nl.
4295 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
4297 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
4298 Problem reported by twlevo@xs4all.nl.
4300 * doc/bison.texinfo: Change @dircategory from "GNU programming
4301 tools" to "Software development". Requested by Richard Stallman
4304 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
4306 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
4307 Problem reported by twlevo@xs4all.nl.
4309 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
4311 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
4312 keyword; it's not needed with modern compilers, and it doesn't
4313 affect correctness with older compilers. Suggested by
4316 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
4318 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
4319 gcc -Wswitch-default.
4320 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
4321 * data/yacc.c (yyparse): Likewise.
4323 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
4325 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
4326 already. Let config.h define any nonstandard values.
4328 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
4330 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
4331 for the benefit of slower hosts. Problem reported by
4334 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
4336 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
4337 being defined and not used.
4338 * data/lalr1.cc (yyparse): Likewise.
4339 Use "if (false)" rather than "if (0)".
4341 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
4343 * TODO: Mention that we should allow NUL bytes in tokens.
4345 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
4347 * src/scan-skel.l (<<EOF>>): Don't close standard output.
4348 Problem reported by Hans Aberg.
4350 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
4352 * src/getargs.c (version): Happy new year; update overall
4353 program copyright date from 2004 to 2005.
4355 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
4356 Problem reported by Hans Aberg.
4357 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
4358 (Output file names.): Add a test for the case when standard output
4361 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
4363 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
4364 to fix an oversight in the Bison 2.0 manual.
4366 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
4368 * NEWS: Version 2.0. Reformat the existing news items since
4369 1.875, so that related items are grouped together.
4370 * configure.ac (AC_INIT): Bump version to 2.0.
4371 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
4373 * tests/torture.at (Exploding the Stack Size with Alloca): Set
4374 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
4375 otherwise, we're not testing alloca. Unfortunately there's no
4376 simple way to consult HAVE_ALLOCA here.
4378 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
4381 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
4382 hand. This avoids a warning about comparing int to size_t when
4383 GCC warnings are enabled.
4385 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
4387 * NEWS: Bison-generated parsers no longer default to using the
4388 alloca function (when available) to extend the parser stack, due
4389 to widespread problems in unchecked stack-overflow detection.
4390 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
4391 responsibility to set it to a positive value. This lets the user
4392 specify a value that is not a preprocessor constant.
4393 * data/yacc.c (YYMAXDEPTH): Likewise.
4394 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
4395 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
4396 to be a compile-time constant. However, explain the constraints on it.
4397 Also, explain the constraints on YYINITDEPTH.
4398 (Table of Symbols): Explain that alloca is no longer the default.
4399 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
4402 * doc/bison.texinfo (Location Default Action): Mention that n must
4403 be zero when k is zero. Suggested by Frank Heckenbach.
4405 2004-12-22 Akim Demaille <akim@epita.fr>
4407 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
4408 (parser::state_type, parser::semantic_type, parser::location_type):
4409 Private, not public.
4410 (parser::parse): Return ints, not bool.
4411 Returning a bool introduces a problem: 0 corresponds to false, and
4412 it seems weird to return false on success. Returning true changes
4413 the conventions for yyparse.
4414 Alternatively we could return void and send an exception.
4415 There is no clear consensus (yet?).
4416 (state_stack, semantic_stack, location_stack): Rename as...
4417 (state_stack_type, semantic_stack_type, location_stack_type): these.
4418 Private, not public.
4419 * tests/c++.at: New.
4420 * tests/testsuite.at, tests/Makefile.am: Adjust.
4422 2004-12-21 Akim Demaille <akim@epita.fr>
4424 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
4426 2004-12-21 Akim Demaille <akim@epita.fr>
4428 Don't impose std::string for filenames.
4430 * data/lalr1.cc (b4_filename_type): New.
4431 (position::filename): Use it.
4432 (parser.hh): Move the inclusion of stack.hh and location.hh below
4433 the user code, so that needed headers for the filename type can be
4435 Forward declare them before the user code.
4436 * tests/Makefile.am (check-local, installcheck-local): Pass
4437 TESTSUITEFLAGS to the TESTSUITE.
4439 2004-12-20 Akim Demaille <akim@epita.fr>
4441 Use more STL like names: my_class instead of MyClass.
4443 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
4444 (SemanticStack, SemanticType, StateStack, StateType)
4445 (TokenNumberType, Stack, Slice, Traits, Parser::location)
4446 (Parser::value): Rename as...
4447 (location_stack, location_type, rhs_number_type, semantic_stack)
4448 (semantic_type, state_stack, state_type, token_number_type, stack)
4449 (slice, traits, parser::yylloc, parser::yylval): these.
4451 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
4453 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
4455 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
4456 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
4458 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
4460 Remove uses of 'short int' and 'unsigned short int'. This raises
4461 some arbitrary limits. It uses more memory but nowadays that's
4462 not much of an issue.
4464 This change does not affect the generated parsers; that's a different
4465 task, as some users will want to conserve memory there.
4467 Ideally we should use size_t to represent all object counts, and
4468 something like ptrdiff_t to represent signed differences of object
4469 counts; but that will require more code-cleanup than I have the
4470 time to do right now.
4472 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
4473 Use size_t, not int or short int, to count objects.
4474 * src/closure.c (nritemset, closure): Likewise.
4475 * src/closure.h (nritemset, closure): Likewise.
4476 * src/nullable.c (nullable_compute): Likewise.
4477 * src/print.c (print_core): Likewise.

4483 * src/gram.h (rule_number, rule): Use int, not short int.
4484 * src/output.c (prepare_rules): Likewise.
4485 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
4486 errs, reductions): Likewise.
4487 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
4489 * src/tables.c (vector_number, tally, action_number,
4490 ACTION_NUMBER_MINIMUM): Likewise.
4491 * src/output.c (muscle_insert_short_int_table): Remove.
4493 2004-12-17 Akim Demaille <akim@epita.fr>
4495 * data/lalr1.cc: Extensive Doxygenation.
4496 (error_): Rename as...
4497 (error): this, since it is visible to the user.
4499 (Parser::message): Now an automatic variable from...
4500 (Parser::yyreport_syntax_error_): here.
4501 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
4503 * tests/input.at: Escape $.
4505 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
4507 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
4508 Parenthesize rhs to avoid obscure problems with mistakes like
4509 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
4510 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
4511 b4_rhs_location): Likewise.
4512 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
4513 b4_rhs_location): Likewise.
4515 2004-12-16 Akim Demaille <akim@epita.fr>
4517 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
4518 yacc.c: be sure to stay within yycheck_.
4519 * tests/actions.at: Re-enable C++ tests.
4521 2004-12-16 Akim Demaille <akim@epita.fr>
4523 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
4526 2004-12-16 Akim Demaille <akim@epita.fr>
4528 Use #define to handle the %name-prefix.
4530 * data/glr.c, data/yacc.c: Comment changes.
4531 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
4532 so that one can refer to yylex in the parser file, and have it
4533 renamed, as is the case with other skeletons.
4535 2004-12-16 Akim Demaille <akim@epita.fr>

4557 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
4559 Fix some problems reported by twlevo at xs4all.
4560 * src/symtab.c (symbol_new): Report an error if the input grammar
4561 contains too many symbols. This is better than calling abort() later.
4562 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
4563 (struct node, struct graph):
4564 Rename member expand to stretch. All uses changed.
4565 (struct graph): Remove member layoutalgorithm. All uses removed.
4566 * src/vcg.c (get_layoutalgorithm_str): Remove. All uses removed.
4567 * src/vcg_defaults.h (G_STRETCH): Renamed from G_EXPAND.

4571 2004-12-15 Akim Demaille <akim@epita.fr>
4573 * data/lalr1.cc: Normalize /** \brief ... */ to ///.
4574 Add more Doxygen comments.
4575 (symprint_, stack_print_, reduce_print_, destruct_, pop)
4576 (report_syntax_error_, translate_): Rename as...
4577 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
4578 (yypop_, yyreport_syntax_error_, yytranslate_): this.
4580 2004-12-15 Akim Demaille <akim@epita.fr>
4582 * data/lalr1.cc (lex_): Rename as...
4584 Move the trace here.
4585 Take the %name-prefix into account.
4586 Reported by Alexandre Duret-Lutz.
4588 2004-12-15 Akim Demaille <akim@epita.fr>
4590 Simplify the C++ parser constructor.
4592 * data/lalr1.cc (debug_): Rename as...
4593 (yydebug_): so that the parser's internals are always in the yy*
4596 (b4_parse_param_decl): Remove the leading comma as it is now only
4597 called as unique argument list.
4598 (Parser::Parser): Remove the constructor accepting a location and
4599 an initial debugging level.
4600 Remove from the other ctor the argument for the debugging level.
4601 (debug_level_type, debug_level, set_debug_level): New.
4603 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
4606 2004-12-15 Akim Demaille <akim@epita.fr>
4608 Remove b4_root related material: failure experiment
4609 (which goal was to allow to derive from a class).
4611 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
4612 definitions and uses.
4614 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
4616 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
4617 not 2, since it's not portable to subtract 1 from the start of an
4618 array. The new item 0 is never set or used. All uses changed.
4620 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
4621 the default definition of YYLLOC_DEFAULT. Problem reported
4622 by Frank Heckenbach.
4624 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
4626 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
4627 the normal case and one for the error case. Just use the
4628 first one uniformly. Problem reported by Frank Heckenbach.
4629 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
4630 use exactly the same macro in both places.
4631 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
4632 so that the normal-case YYRHSLOC works for the error case too.
4634 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
4635 (YYLLOC_DEFAULT): Use the same macro as glr.c.
4636 * doc/bison.texinfo (Location Default Action): Don't claim that
4637 we have an array of locations. Use the same macro for both glr
4638 and lalr parsers. Mention YYRHSLOC. Mention what happens when
4641 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
4643 * HACKING: Update email addresses to send announcements to.
4645 * configure.ac (AC_INIT): Bump version to 1.875f.
4647 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
4649 * NEWS: Version 1.875e.
4650 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
4652 * src/scan-skel.l: Include "complain.h", for "fatal".
4654 * src/relation.h (relation_print, relation_digraph):
4655 Relation sizes are of type relation_node, not size_t (this is
4656 merely a doc fix, since the two types are equivalent).
4657 (relation_transpose): Relation sizes are of type relation_node,
4659 * src/relation.c: Likewise.
4660 (top, infinity): Now of type relation_node, not int.
4661 (traverse, relation_transpose): Use relation_node, not int.
4663 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
4664 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
4665 (yyparse): Remove unused local introduced in 2004-10-25 patch.
4667 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
4668 specifying whether the test should be skipped. Use it tp
4669 specify that the [%defines %skeleton "lalr1.cc"] tests currently
4670 fail on some hosts, and should be skipped.
4672 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
4674 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
4675 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
4676 unless otherwise specified below.
4678 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
4679 to allocate kernel_base, kernel_items, kernel_size, since
4680 they needn't be initialized to 0.
4681 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
4682 * src/closure.c (new_closure): Likewise, for itemset.
4683 * src/derives.c (derives_compute): Likewise, for delts, derives, q.
4684 * src/lalr.c (set_goto_map): Likewise, for temp_map.
4685 (initialize_F): Likewise, for reads, edge, reads[i], includes[i].
4686 (build_relations): Likewise for edge, states1, includes.
4687 * src/nullable.c (nullable_compute): Likewise, for squeue, relts.
4688 * src/reader.c (packgram): Likewise, for ritem, rules.
4689 * src/reduce.c (nonterminals_reduce): Likewise for nontermmap.
4690 * src/relation.c (relation_digraph): Likewise for VERTICES.
4691 (relation_transpose): Likewise for new_R, end_R.
4692 * src/symtab.c (symbols_token_translations_init): Likewise for
4694 * src/tables.c (save_row): Likewise for froms, tos, conflict_tos.
4695 (token_actions): Likewise for yydefact, actrow, conflrow,
4697 (save_column): Likewise for froms[symno], tos[symno].
4698 (goto_actions): Likewise for state_count.
4699 (pack_table): Likewise for base, pos, check.
4700 (tables_generate): Likewise for width.
4702 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
4703 for initial core. Just have a separate core, so we needn't worry
4704 about whether kernel_size and kernel_base are initialized.
4706 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
4707 kernel_size, kernel_items): Remove unnecessary initialization.
4708 * src/conflicts.c (conflicts): Likewise.
4709 * src/derives.c (derives): Likewise.
4710 * src/muscle_tablc (muscle_insert): Likewise.
4711 * src/relation.c (relation_digraph): Likewise.
4712 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
4713 conflrow, conflict_table, conflict_list, table, check):
4716 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
4717 This is because all callers pass unsigned int.
4718 * src/closure.h (new_closure): Likewise.
4720 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
4721 (build_relations): Initialize includes[i] in all cases.
4722 * src/reader.c (packgram): Always initialize rules[ruleno].prec
4723 and rules[ruleno].precsym. Initialize members in order.
4724 * src/relation.c (relation_transpose): Always initialize new_R[i]
4726 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
4728 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
4729 conflict_list[0] was always 0, but now it isn't initialized.
4731 * src/table.c (table_grow): When conflict_table grew, the grown
4732 area wasn't cleared. Fix this.
4734 * lib/.cvsignore: Add strdup.c, strdup.h.
4735 * m4/.cvsignore: Add strdup.m4.
4737 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
4739 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
4740 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
4741 GOTO_NUMBER_MAXIMUM, since we occasionally compute
4742 ngotos + 1 without checking for overflow.
4743 (build_relations): Use END_NODE, not -1, to denote end of edges.
4744 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
4745 build_relations): Use goto_number, not int, for goto numbers.
4746 * src/tables.c (save_column, default_goto): Likewise.
4748 2004-11-23 Akim Demaille <akim@epita.fr>
4750 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
4751 of #defining from yystype.
4752 Don't typedef yystype, C++ does not need it.
4753 This lets it possible to forward declare it as union.
4755 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
4757 * bootstrap (gnulib_modules): Add extensions.
4758 Problem reported by Jim Meyering.
4760 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
4762 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
4763 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
4764 src/system.h, src/tables.c: XFREE -> free, to accommodate
4765 recent change to gnulib xalloc.h.
4766 Problem reported by Jim Meyering.
4768 2004-11-17 Akim Demaille <akim@epita.fr>
4770 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
4772 2004-11-17 Akim Demaille <akim@epita.fr>,
4773 Alexandre Duret-Lutz <adl@gnu.org>
4775 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
4778 Use it instead of cdebug_.
4779 (Parser::debug_stream, Parser::set_debug_stream): New.
4780 (Parser::symprint_): Define cdebug_ for temporary backward
4782 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
4785 2004-11-17 Akim Demaille <akim@epita.fr>
4787 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
4788 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
4789 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
4790 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
4792 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
4794 * data/glr.c (yyloc_default): Remove; not used.
4795 Problem reported by Frank Heckenbach.
4797 2004-10-25 Akim Demaille <akim@epita.fr>
4799 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
4800 Introduce another definition to address simple location arrays.
4801 (yyGLRStack): New member: yyerror_range.
4802 (yyrecoverSyntaxError, yyparse): Update it.
4803 (yyrecoverSyntaxError): Use it when shifting the error token to
4804 have an accurate range, equivalent to the one computed by both
4805 yacc.c and lalr1.cc.
4806 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
4807 that column numbers start at column 0, as per GNU Coding
4808 Standards, the others tests, and the doc.
4809 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
4810 Adjust to the above change (first column is 0).
4811 And adjust the location of the "<error>", now covering the whole
4814 2004-10-22 Akim Demaille <akim@epita.fr>
4815 and Paul Eggert <eggert@cs.ucla.edu>
4817 Remove some arbitrary limits on goto numbers and relations.
4818 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
4819 initial values, since they're never used.
4820 (set_goto_map): ngotos is now unsigned, so test for overflow
4821 by seeing whether it wraps around to zero.
4822 * src/lalr.h (goto_number): Now size_t, not short int.
4823 (GOTO_NUMBER_MAXIMUM): Remove.
4824 * src/relation.c (relation_print, traverse, relation_transpose):
4825 Check for END_NODE rather than looking at sign.
4826 * src/relation.h (END_NODE): New macro.
4827 (relation_node): Now size_t, not short int.
4829 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
4831 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
4832 keyword, not an identifier. Problem reported by Baron Schwartz in
4833 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
4835 2004-10-11 Akim Demaille <akim@epita.fr>
4837 * src/symtab.c (symbol_check_alias_consistency): Also check
4838 type names, destructors, and printers.
4839 Reported by Alexandre Duret-Lutz.
4840 Recode the handling of associativity and precedence in terms
4841 of symbol_precedence_set.
4842 Accept no redeclaration at all, not even equal to the previous
4844 (redeclaration): New.
4845 Use it to factor redeclaration complaints.
4846 (symbol_make_alias): Don't set the type of the alias, let
4847 symbol_check_alias_consistency do it as for other features.
4848 * src/symtab.h (symbol): Add new member prec_location, and
4850 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
4851 * tests/input.at (Incompatible Aliases): New.
4853 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
4855 .cvsignore fixes to accommodate gnulib changes,
4856 and the practice of naming build directories "_build".
4857 * .cvsignore: Add "_*". Sort.
4858 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
4859 * m4/.cvsignore: Add "*_gl.m4".
4861 2004-10-06 Akim Demaille <akim@epita.fr>
4863 * src/parse-gram.y (add_param): Fix the truncation of trailing
4866 2004-10-05 Akim Demaille <akim@epita.fr>
4868 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
4869 whether the reducion was empty or not. This leaves room to
4870 improve the use of YYLLOC_DEFAULT in such a case.
4871 lalr1.cc is still experimental, so changing this is acceptable.
4872 And finally, there are probably not many users who changed the
4873 handling of locations in GLR, so changing is admissible too.
4875 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
4876 empty reduction, set @$ to an empty location ending the previously
4878 Adjust uses to make sure the code is triggered on empty
4880 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
4881 expected output: empty reductions have empty locations.
4883 2004-09-29 Akim Demaille <akim@epita.fr>
4885 * data/lalr1.cc: Move towards a more standard C++ coding style
4886 for templates: Class < T > -> Class<T>.
4888 2004-09-29 Akim Demaille <akim@epita.fr>
4890 * data/lalr1.cc: Reinstall the former ctor, for sake of
4891 compatibility, but warn it will be removed.
4892 Move towards a more standard C++ coding style (i.e., type *var ->
4895 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
4897 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
4898 since it's less likely to work if NULs are involved in the future.
4900 2004-09-27 Akim Demaille <akim@epita.fr>
4902 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
4904 2004-09-27 Akim Demaille <akim@epita.fr>
4906 * data/lalr1.cc (b4_parse_param_decl_1): New.
4907 (b4_parse_param_decl): Use it to have different names between attribute
4909 (b4_cc_constructor_call): Likewise.
4911 2004-09-24 Akim Demaille <akim@epita.fr>
4913 * src/parse-gram.y (add_param): Strip the leading and trailing
4914 blanks from a formal argument declaration.
4915 (YY_LOCATION_PRINT): New.
4917 2004-09-24 Akim Demaille <akim@epita.fr>
4919 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
4922 2004-09-24 Akim Demaille <akim@epita.fr>
4924 * doc/bison.texinfo (Table of Symbols): Sort.
4926 2004-09-21 Akim Demaille <akim@epita.fr>
4928 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
4929 the useless parentheses.
4930 Suggested by Paul Eggert.
4932 2004-09-20 Akim Demaille <akim@epita.fr>
4934 Let the initial-action act on the look-ahead, and use it for the
4935 "initial push" (corresponding to an hypothetical beginning-of-file).
4936 And let lalr1.cc honor %initial-action.
4938 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
4940 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
4941 (Parser::Parser): Remove the ctor that used to initialize it.
4942 (Parser::parse): Like in the other skeletons, issue the "starting
4943 parse" message before any action.
4944 Honor %initial-action.
4945 Initialize the stacks with the lookahead.
4946 * data/yacc.c: Let $$ and @$ in %initial-action designate the
4948 Push them in the stacks.
4949 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
4951 2004-09-20 Akim Demaille <akim@epita.fr>
4953 * doc/bison.texinfo (Initial Action Decl): New.
4955 2004-09-20 Akim Demaille <akim@epita.fr>
4957 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
4958 clearer criterion to define it.
4959 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
4960 When reducing on an empty RHS, use the latest stacked location as
4962 yylloc is not always available.
4963 * data/glr.c: Likewise.
4964 Also, honor initial-actions.
4966 2004-09-20 Akim Demaille <akim@epita.fr>
4968 * data/yacc.c (YY_LOCATION_PRINT): New.
4969 Define when we know YYLTYPE's structure, i.e., when the default
4970 YYLLOC_DEFAULT is used.
4971 * data/c.m4 (b4_yysymprint_generate): Use it.
4972 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
4973 value of the result.
4974 (error_start_): Replace with...
4975 (error_range_): this location array.
4976 This allows to replace code relying on the implementation of
4977 locations by portable code.
4978 * data/yacc.c (yylerrsp): Replace with...
4979 (yyerror_range): this.
4980 Every time a token is popped, update yyerror_range[0], to have an
4981 accurate location for the error token.
4982 * data/glr.c (YY_LOCATION_PRINT): New.
4983 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
4984 deference a pointer.
4985 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
4986 report the location in %printers.
4988 * src/scan-skel.l: Instead of abort, report error messages to ease
4989 understanding skeleton scanning failures.
4991 2004-09-16 Akim Demaille <akim@epita.fr>
4993 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
4994 (iterator, const_iterator): these, to be more in the C++ spirit.
4995 Also, return reverse iterators so that when displaying the stack
4996 we display its bottom first.
4997 (Parser::stack_print_, Parser::reduce_print_): Match the messages
4999 We should probably use vector here though.
5001 2004-09-16 Akim Demaille <akim@epita.fr>
5003 Have more complete shift traces.
5005 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
5006 to report Shifts instead of ad hoc YYDPRINTF invocations,
5007 including for the error token.
5008 * data/lalr1.cc (symprint_): Output the location.
5009 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
5010 output the location within the %printer.
5011 Activate GLR tests, at least to make sure they compile properly.
5012 They still don't pass though.
5013 * tests/calc.at: Adjust expect verbose output, since now "Entering
5014 state..." is on a different line than the "Shifting" message.
5016 2004-09-08 Akim Demaille <akim@epita.fr>
5018 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
5019 Bison directive from the Bison file to the invocation of this
5020 macro, so that these directives are passed to
5021 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
5022 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
5023 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
5024 the extra Bison directives instead of the whole series.
5025 Change the grammar so that there are recoverable errors, and
5026 unrecoverable errors. Now we can have the parser give up before
5027 consuming the whole input. As a result we now can observe that
5028 the lookahead is freed when needed.
5029 Change the parser source to parse argv[1] instead of a hard coded
5031 Simplify yylex, and give a value and location to EOF.
5032 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
5033 passed directives already coded in the file.
5034 Add some tests to check the location of "error".
5035 For some tests, the C++ parser is correct, and not yacc.c.
5036 For other tests, they provide different, but unsatisfying, values,
5037 so keep the C++ value so that at least one parser is "correct"
5038 according to the test suite.
5039 (Actions after errors): Remove, this is subsumed by the
5040 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
5042 2004-09-06 Akim Demaille <akim@epita.fr>
5044 * data/lalr1.cc: Adjust the indentation of the labels.
5048 2004-09-06 Akim Demaille <akim@epita.fr>
5050 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
5051 argument, an informative message.
5052 Call YY_SYMBOL_PRINT.
5053 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
5054 * data/lalr1.cc (destruct_): Likewise.
5055 In addition, no longer depend on b4_yysymprint_generate and
5056 b4_yydestruct_generate to generate these functions, do it "by
5059 2004-09-03 Akim Demaille <akim@epita.fr>
5061 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
5062 invoked, yydestruct the lookahead.
5063 * tests/calc.at (Calculator $1): Update the expected lengths of
5064 traces: there is an added line for the discarded lookahead.
5065 * doc/bison.texinfo (Destructor Decl): Some rewording.
5066 Define "discarded" symbols.
5068 2004-09-02 Akim Demaille <akim@epita.fr>
5070 * data/lalr1.cc (translate_, destruct_): No reason to be static.
5072 2004-09-02 Akim Demaille <akim@epita.fr>
5074 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
5075 (YYDSYMPRINTF): Rename as...
5076 (YY_SYMBOL_PRINT): this.
5077 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
5079 Use it instead of direct symprint_ calls.
5080 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
5083 2004-09-02 Akim Demaille <akim@epita.fr>
5085 * data/lalr1.cc (b4_yysymprint_generate): New.
5086 (symprint_): New member function, defined when YYDEBUG.
5087 Use it consistently instead of token/nterm debugging output by
5089 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
5090 %printer calls to use cdebug_ when using lalr1.cc.
5092 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
5094 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
5095 with #ifdef YYDEBUG.
5097 2004-08-26 Akim Demaille <akim@epita.fr>
5099 * doc/bison.texinfo (Implementing Loops): Rename as...
5100 (Implementing Gotos/Loops): this.
5102 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
5104 Adjust to latest gnulib.
5105 * bootstrap (gnulib_modules): Add xalloc-die.
5106 Set LC_ALL=C so that file names sort consistently.
5107 Prefer the gnulib copies of gettext.m4, glibc21.m4,
5108 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
5109 uintmax_t.m4, ulonglong.m4.
5110 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
5111 po.m4 since we are now using _gl.m4 instead.
5113 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
5115 * src/scan-action.l: Remove. Scanning of semantic actions is
5116 handled in scan-gram.l.
5118 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
5120 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
5122 * src/location.h (struct): The file member is a uniqstr.
5123 (equal_boundaries): Use UNIQSTR_EQ for comparison.
5125 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
5127 Fix bug with non-%union parsers that have printers or destructors,
5128 which led to a Bison core dump. Reported by Peter Fales in
5129 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
5131 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
5132 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
5133 not to our own type.
5134 * src/output.c (symbol_destructors_output, symbol_printers_output):
5135 Don't assume %union.
5136 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
5137 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
5138 UNION-FLAG. All callers changed.
5139 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
5140 Use type char, not unsigned int, when declaring an array of char;
5141 this lets us remove a cast.
5142 (Printers and Destructors): Add non-%union test cases.
5144 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
5146 * doc/bison.texinfo: Minor editorial changes, mostly to the new
5147 GLR writeups. E.g., avoid frenchspacing and the future tense,
5148 change "lookahead" to "look-ahead", and change "wrt" to "with
5151 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
5153 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
5154 New sections, split off from the GLR Parsers section. Put the new
5155 Simple GLR Parser near the start of the GLR section, for clarity.
5156 Rewrite connective text.
5158 2004-06-21 Frank Heckenbach <frank@g-n-u.de>

5214 C++ compiler. (trivial change)
5216 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
5218 Spent a few hours checking out which prerequisite versions the
5219 current sources actually require. I went all the way back to
5220 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
5221 a seemingly endless set of combinations of versions more recent
5222 than that. The bottom line is that the current sources require
5223 fairly recent versions of the build tools, and it'll be some work
5225 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
5226 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
5227 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
5228 Add comments explaining why those particular versions are
5231 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
5232 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
5233 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
5235 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
5236 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
5238 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
5240 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
5241 0.11.5. Suggested by Bruno Haible.
5242 * bootstrap: Remove gettext version checking.
5244 * doc/bison.texinfo (Decl Summary): Also mention that %union
5245 can depend on prerequisite types. Problem reported by Tim
5248 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
5250 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
5251 * README-alpha: Don't tell people not to package this.
5253 * bootstrap: Don't assume $(...) works; use `...` instead.
5254 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
5257 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
5258 put into the -d output file, and mention what to do if YYSTYPE is
5261 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
5263 Undo change made earlier today: it caused autopoint to not bring
5264 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
5267 * bootstrap: Check that gettext version matches what's in
5268 configure.ac. Warn users to ignore robots.txt ERROR 404.
5269 * bootstrap: Undo today's earlier change (logged below).
5270 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
5272 The gettext version checking is causing more trouble than it's
5273 curing; remove it. Problem reported by Paul Hilfinger.
5275 * bootstrap: Issue a warning that one can expect a message
5276 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
5277 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
5279 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
5281 Ensure that the C++ compiler used for testing actually works on a
5282 simple test program; if not, skip the C++-related tests. Problem
5283 reported by Vin Shelton in:
5284 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
5286 * m4/cxx.m4: New file.

5293 * data/glr.c (yylloc): Output this macro even if locations are not
5294 being generated, as the GLR parser needs it even in that case.
5295 Problem reported by Troy A. Johnson
5296 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
5298 * configure.ac (AC_INIT): Update to 1.875e.
5300 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>

5304 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
5306 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
5307 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
5308 lalr1.cc runs afoul of the first, and the last two are no longer
5309 supported by GCC 3.4.0.
5310 * README: Mention GNU m4 1.4 or later; mention m4 patches.
5311 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
5313 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
5315 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not
5316 unsigned int, for compatibility with latest gnulib hash module.

5337 Fix typo by replacing $1 with $option.
5338 Remove more 'intl'-related files.
5339 Don't DEFUN AM_INTL_SUBDIR twice.
5341 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,
5342 memrchr.c, strcasecmp.c, strchr.c, strrchr.c, strspn.c, strtol.c,
5344 * m4/.cvsignore: Add exitfail.m4, extensions.m4, gnulib.m4,
5345 hard-locale.m4, mbstate_t.m4, strerror_r.m4, strndup.m4,

5347 inttypes.m4, inttypes_h.m4, isc-posix.m4, lcmessage.m4,
5348 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
5349 * src/.cvsignore: Add *.output.
5351 * src/parse-gram.y: Put copyright notice inside %{ %} so it
5352 gets copied to the output file.
5354 2004-04-28 Paul Eggert <eggert@twinsun.com>
5356 Get files from the gnulib and po repositories, instead of relying
5357 on them being in our CVS. Upgrade to latest versions of gnulib
5360 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
5361 * bootstrap: Bootstrap from gnulib and po repositories.
5362 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
5363 * README-cvs: Document these changes. Remove version numbers from
5364 mentions of build tools, since they change so often. Mention Flex.
5366 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.

5368 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
5369 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
5371 (AC_ISC_POSIX): Remove; we no longer support this
5372 ancient OS, as it gets in the way of latest Autoconf & gnulib.
5373 (AC_HEADER_STDC): Remove: we now assume C89 or better.
5374 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
5375 Do not check for C89 headers, except for locale.h which is used
5376 by the Yacc library and must port to K&R hosts.
5377 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
5378 Do not check for C89 functions, except for setlocale which is
5379 used by the Yacc library.
5380 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.
5381 (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR,
5382 gl_FUNC_MEMRCHR, gl_FUNC_STPCPY, gl_FUNC_STRNLEN, gl_FUNC_STRTOL,

5384 gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC,
5385 AM_GNU_GETTEXT): Remove; now done by:
5386 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
5387 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
5390 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
5391 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
5392 Define to empty, as gnulib.mk will do the rest for us.
5393 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
5395 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
5396 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
5398 * src/files.c: Include gnulib's xstrndup.h.
5400 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
5401 (REALLOC): Use xnrealloc, for likewise.
5402 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.

5427 Remove, as these files are now generated automatically
5428 by bootstrap or automake.

5456 2004-04-27 Paul Eggert <eggert@twinsun.com>
5458 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
5459 case, as stos_ is now used by destructors due to the 2004-02-09

5486 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
5487 so that this include file can stand alone.

5489 does this now. Include subpipe.h first after config.h, to
5490 test whether it can stand alone.
5492 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
5493 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
5496 * tests/synclines.at (%union synch line): Put a dummy member in
5497 the union, because empty unions aren't allowed in C. Caught
5500 2004-04-13 Jim Meyering <jim@meyering.net>

5561 (conflicts_print): Check r/r conflicts against expected_rr_conflicts
5563 Use expected_sr_conflicts in place of expected_conflicts.
5564 Warn if expected_rr_conflicts used in non-GLR parser.

5580 handle_action_dollar, handle_action_at, convert_ucn_to_byte):
5581 Say "long int", not "long", for uniformity with GNU style.

5585 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
5586 compilers. This fixes a problem with Intel's C++ compiler being
5587 chatty, reported by Guido Trentalancia in
5588 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.

5602 error_start_ when erroneous token are discarded.
5603 (Parser::parse) <yyerrlab1>: Compute the location of the error
5604 token so that it covers all the discarded tokens.
5605 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
5606 it can be called with `%skeleton "lalr1.cc"', and do that.
5608 2004-02-02 Paul Eggert <eggert@twinsun.com>
5610 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
5611 $(top_srcdir)/lib and ../lib. This fixes a bug reported
5612 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
5613 There's no need to mention top_builddir since Automake does that
5615 (INCLUDES): Remove, as Automake says it's obsolescent.
5616 Contents migrated into AM_CPPFLAGS as described above.
5617 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
5619 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
5621 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.

5633 * src/output.c (output_skeleton): Rename local var.
5634 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
5635 Bison tokens, as this runs afoul of the 2003-10-07 change that
5636 disallowed NUL bytes in character constants or string literals.
5638 * tests/local.at: Require Autoconf 2.59's Autotest.
5639 * tests/testsuite.at: Don't include local.at, since we now assume
5640 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
5642 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
5643 multiple inclusion warnings.

5665 2003-10-05 Paul Eggert <eggert@twinsun.com>
5667 * NEWS: Don't document %no-default-prec, as it's still
5669 * doc/bison.texinfo: Document %no-default-prec only if
5670 the defaultprec flag is set. Normally it's not.
5672 2003-10-04 Paul Eggert <eggert@twinsun.com>
5674 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
5675 non-modifiable lvalue, instead of a modifiable one.
5676 * doc/bison.texinfo (Actions): Document that $$ can
5677 be assigned to. Do not claim that $$ and $N are
5678 array element references: user code should not rely on this.

5733 * config/announce-gen, Makefile.cfg: New.
5734 * Makefile.am: Adjust.
5735 * GNUmakefile, Makefile.maint: Update from CVS Autoconf, but
5736 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
5738 2003-08-25 Akim Demaille <akim@epita.fr>
5740 When reducing initial empty rules, Bison parser read an initial
5741 location that is not defined. This results in garbage, and that
5742 affects Bison's own parser. Therefore we need (i) to extend Bison
5743 to support a means to initialize this location, and (ii) to use
5744 this CVS Bison to fix CVS Bison's parser.
5746 * src/reader.h, reader.c (epilogue_augment): Remove, replace
5748 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
5749 * src/parse-gram.y: Adjust.

5751 (%error-verbose): Since we require CVS Bison, there is no reason
5753 * src/scan-gram.l: Adjust.
5754 * src/Makefile.am (YACC): New, to make sure we use our own parser.
5755 * data/yacc.c (yyparse): Use b4_initial_action.

5761 2003-08-25 Akim Demaille <akim@epita.fr>
5763 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
5764 From Alexandre Duret-Lutz.

5783 error recovery loops. This patch is based on
5784 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
5785 Also, augment the similarity between lalr1.cc and yacc.c.
5786 Note: the locations of error recovery rules are not correct yet.
5788 * data/lalr1.cc: Comment changes to augment the similarity between
5789 lalr1.cc and yacc.c.
5790 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
5791 (yyerrlab1): Remove, but where it used to be (now the bottom part of
5792 yyerrlab), when hitting EOF, pop the whole stack here instead of
5793 merely falling thru the default error handling mechanism.
5794 (yyerrorlab): New label, with the old contents of YYERROR,
5795 plus the following change: pop the stack of rhs corresponding
5796 to the production that invoked YYERROR. That is how Yacc
5797 behaves (required by POSIX).
5798 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
5801 2003-08-25 Akim Demaille <akim@epita.fr>
5803 Tune local.at so that people can "autom4te -l autotest calc.at -o
5804 calc" for instance, to extract a sub test suite.
5806 * tests/testsuite.at: Move the initialization, Autotest version
5807 requirement, and AT_TESTED invocation into...
5808 * tests/local.at: here.
5809 * tests/testsuite.at: Include it for compatibility with Autoconf
5811 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
5814 2003-08-04 Paul Eggert <eggert@twinsun.com>
5816 Rework code slightly to avoid gcc -Wtraditional warnings.
5817 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
5818 The returned value is now stored in *YY0. All callers changed.
5819 * src/output.c (merge_output): Adjust to the above change.
5821 2003-07-26 Paul Eggert <eggert@twinsun.com>
5823 * data/glr.c (YYASSERT): New macro.
5824 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
5825 yyresolveStates, yyprocessOneStack):
5826 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
5827 Derived from a suggestion by Frank Heckenbach.
5829 2003-07-25 Paul Eggert <eggert@twinsun.com>
5831 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
5832 for portability to K&R C (after ansi2knr, presumably). See
5833 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
5834 by Frank Heckenbach, though I have omitted the structure-initialization
5835 part of his glr-knr.diff patch since I recall that the Portable
5836 C Compiler didn't require that change.
5838 Let the user specify how to allocate and free memory.
5839 Derived from a suggestion by Frank Heckenbach in
5840 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
5841 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
5842 All uses of free, malloc, realloc changed to use these macros,
5843 and unnecessary casts removed.

5846 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
5848 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
5849 use s.empty() rather than s == "" to test for empty string; see
5850 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
5853 2003-06-25 Akim Demaille <akim@epita.fr>
5855 * config/depcomp, config/install-sh: Update from masters.
5857 2003-06-20 Paul Eggert <eggert@twinsun.com>
5859 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
5860 and return properly parenthesized result.
5861 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
5862 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
5863 Remove unnecessary parentheses from uses.
5864 * doc/bison.texinfo (Location Default Action): Describe the
5865 conventions for parentheses.
5867 2003-06-19 Paul Eggert <eggert@twinsun.com>
5869 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
5870 yyreportTree): Do not assume that size_t is the same width as int,
5871 when printing sizes. Print sizes using an unsigned format.
5872 Problem reported by Frank Heckenbach in
5873 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
5875 Port to Forte Developer 7 C compiler.
5876 * data/glr.c (struct YYLTYPE): If locations are not being used,
5877 declare a single dummy member, as empty structs do not conform
5879 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
5880 the Forte Developer 7 C compiler complains that end-of-loop
5881 code is not reached.
5883 2003-06-17 Paul Eggert <eggert@twinsun.com>
5885 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
5886 avoid warnings from picky compilers about redefinition of PARAMS.
5888 2003-06-17 Paul Eggert <eggert@twinsun.com>
5892 * NEWS: Document 1.875b.
5894 * lib/bbitset.h: Do not include config.h; that's the includer's job.
5895 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
5896 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
5897 Don't use 'index' in comments, as it's a builtin fn on some hosts.
5898 * lib/bitset_stats.c: Include gettext.h unconditionally, as
5899 per recent gettext manual's suggestion.
5900 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):

5925 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
5926 `How Can I Reset @code{yyparse}', since texinfo does not allow
5927 arbitrary @ in node names.
5929 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
5930 shouldn't be needed according to the gettext 0.12.1 documentation
5931 but which seem to be needed anyway: codeset.m4 glibc21.m4
5932 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4

5954 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
5955 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
5956 the tests right now.
5957 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
5958 yyerror are declared before use; C99 requires this.

5962 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
5964 (yyrecoverSyntaxError): Correct the logic for setting and testing
5966 Correct comment on handling EOF.
5967 Allow states with only a default reduction, rather than failing

5970 Fixes to avoid problem that $-N rules in GLR parsers can cause
5971 buffer overruns, corrupting state.
5973 * src/output.c (prepare_rules): Output max_left_semantic_context
5975 * src/reader.h (max_left_semantic_context): New variable declaration.
5976 * src/scan-gram.l (max_left_semantic_context): Define.

5985 * data/glr.c (YYLTYPE): Make trivial if locations not used.
5986 (YYRHSLOC): Add parentheses, and define only if locations used.
5987 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if

5990 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
5992 * tests/cxx-type.at: Exercise location information; update tests
5993 to differentiate output with and without locations.
5994 Remove forward declarations of yylex and yyerror---caused errors
5995 because default YYLTYPE not yet defined.
5996 Change semantic actions to compute strings, rather than printing
5997 them directly (to test proper passing of semantics values). Change
5998 output to prefix notation and update test data and expected results.
5999 (yylex): Track locations.
6000 (stmtMerge): Return value rather than printing, and include arguments
6003 2003-06-03 Paul Eggert <eggert@twinsun.com>

6011 yy::Slice::operator[] (unsigned),
6012 yy::Slice::operator[] (unsigned) const):
6013 Rename local vars to avoid warnings.
6014 * tests/glr-regression.at (Improper handling of embedded actions
6015 and $-N in GLR parsers): Remove unused local variable from yylex.
6016 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
6017 (void) as arg when not pure, since we now assume C89 when building
6018 Bison. Pacify GCC by using parameter.
6020 2003-06-02 Paul Eggert <eggert@twinsun.com>
6022 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
6023 yy::Location::lines, yy::Location::columns): Rename arguments
6024 to avoid shadowing; this removes a warning generated by GCC 3.3.
6026 2003-06-01 Paul Eggert <eggert@twinsun.com>
6028 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
6029 to g++, as GCC 3.3 complains if you do it.
6030 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
6031 everything that WARNING_CFLAGS has, except omit warnings
6032 not suitable for C++.
6033 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
6034 * tests/atlocal.in (CXXFLAGS): New var.
6035 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
6037 Fix a GLR parser bug I reported in February; see
6038 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
6039 The problem was that GLR parsers did not conform to the C standard,
6040 because actions like { $1 = $2 + $3; } expanded to expressions
6041 that invoked YYFILL in separate subexpressions, and YYFILL assigned
6042 to a local variable. The C standard says that expressions
6043 like (var = f ()) + (var = f ()) have undefined behavior.
6044 Another problem was that GCC sometimes issues warnings that
6045 yyfill and its parameters are unused.
6047 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
6049 (yyfill): New function.
6051 (yyuserAction): Change type of yynormal to bool, so that it matches
6052 the new yyfill signature. Mark it as possibly unused.
6055 Follow up on a bug I reported in February, where a Bison-generated
6056 parser can loop. Provide a test case and a fix for yacc.c. I
6057 don't have a fix for lalr1.cc or for glr.c, unfortunately.
6058 The original bug report is in:
6059 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
6061 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
6062 macro's size was becoming unwieldy.
6063 (yyerrlab): Do not discard an empty lookahead symbol, as this
6064 might destroy garbage.
6065 (yyerrorlab): New label, with the old contents of YYERROR,
6066 plus the following change: pop the stack of rhs corresponding
6067 to the production that invoked YYERROR. That is how Yacc
6068 behaves, and POSIX requires this behavior.
6069 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
6070 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
6071 Define 'alarm' to do nothing if unistd.h is not available.
6072 Add a new rule "exp: '-' error;" to test the above change to
6073 data/yacc.c. Use 'alarm' to abort any test taking longer than
6074 10 seconds, as it's probably looping.
6075 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
6076 Also, the new yacc.c generates two fewer diagnostics for an
6079 2003-05-24 Paul Eggert <eggert@twinsun.com>
6081 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
6082 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
6083 This fixes a problem reported by John Bowman when the Compaq/HP
6084 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
6086 * data/yacc.c (union yyalloc): Likewise.
6087 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
6089 Switch from 'int' to 'bool' where that makes sense.
6091 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,
6092 abitset_subset_p, abitset_disjoint_p, abitset_and_cmp,
6093 abitset_andn_cmp, abitset_or_cmp, abitset_xor_cmp, abitset_and_or,
6094 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
6095 Return or accept bool, not int. All callers changed.
6096 * lib/bbitset.h: (bitset_toggle_, bitset_copy_, bitset_and_or_cmp_,
6097 bitset_andn_or_cmp_, bitset_or_and_cmp_): Likewise.
6098 * lib/bitset.c (bitset_only_set_p, bitset_print, bitset_toggle_,
6099 bitset_copy_, bitset_op4_cmp, bitset_and_or_cmp_, bitset_andn_or_cmp_,
6100 bitset_or_and_cmp_): Likewise.
6101 * lib/bitset.h (bitset_test, bitset_only_set_p): Likewise.
6102 * lib/bitset_stats.c (bitset_stats_print, bitset_stats_toggle,

6109 ebitset_test, ebitset_empty_p, ebitset_subset_p, ebitset_disjoint_p,
6110 ebitset_op3_cmp, ebitset_and_cmp, ebitset_andn_cmp, ebitset_or_cmp,
6111 ebitset_xor_cmp): Likewise.
6112 * lib/lbitset.c (lbitset_elt_zero_p, lbitset_equal_p, lbitset_copy_cmp,
6113 lbitset_test, lbitset_empty_p, lbitset_subset_p, lbitset_disjoint_p,
6114 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
6115 lbitset_xor_cmp): Likewise.
6116 * lib/bbitset.h: Include <stdbool.h>.
6117 (struct bitset_vtable): The following members now return bool, not
6118 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
6119 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
6121 * src/conflicts.c (count_rr_conflicts): Likewise.
6122 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
6124 * lib/ebitset.c (ebitset_obstack_init): Likewise.
6125 * lib/lbitset.c (lbitset_obstack_init): Likewise.
6126 * src/getargs.c (debug_flag, defines_flag, locations_flag,
6127 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
6128 graph_flag): Likewise.
6129 * src/getargs.h (debug_flag, defines_flag, locations_flag,
6130 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
6131 graph_flag): Likewise.

6133 * src/output.h (error_verbose): Likewise.
6134 * src/reader.c (start_flag, typed): Likewise.
6135 * src/reader.h (typed): Likewise.
6136 * src/getargs.c (LOCATIONS_OPTION): New constant.
6137 (long_options, getargs): Use it.
6138 * src/lalr.c (build_relations): Use bool, not int.
6139 * src/nullable.c (nullable_compute): Likewise.
6140 * src/print.c (print_reductions): Likewise.
6141 * src/tables.c (action_row, pack_vector): Likewise.
6142 * src/muscle_tab.h (MUSCLE_INSERT_BOOL): New macro.
6143 * src/output.c (prepare): Use it.
6144 * src/output.c (token_definitions_output,
6145 symbol_destructors_output, symbol_destructors_output): Use string,
6146 not boolean integer, to keep track of whether to output separator.
6147 * src/print_graph.c (print_core): Likewise.
6148 * src/state.c (state_rule_lookaheads_print): Likewise.
6150 * config/install-sh: Sync from automake 1.7.5.
6152 2003-05-14 Paul Eggert <eggert@twinsun.com>
6154 * src/parse-gram.y (rules_or_grammar_declaration): Require a
6155 semicolon after a grammar declaration, in the interest of possible
6156 future changes to the Bison input language.
6157 Do not allow a stray semicolon at the start of the grammar.
6158 (rhses.1): Allow one or more semicolons after any rule, including
6159 just before "|" as required by POSIX.
6160 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
6163 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
6165 %parse-param support for lalr1.cc.
6167 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
6168 b4_cc_constructor_calls, b4_cc_constructor_call,
6169 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
6171 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
6172 parse-param arguments.
6173 (yy::b4_parser_class_name): Declare instance variables to
6174 hold parse-param arguments.
6175 * tests/calc.at: s/value/semantic_value/ because value clashes
6176 with a member of yy::b4_parser_class_name. Adjust C++ code
6177 to handle %parse-param. Enable %parse-param test in C++.
6179 2003-05-12 Paul Eggert <eggert@twinsun.com>
6181 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
6182 English a bit. Fix fclose typo. Change "const char" to "char
6183 const", and use ANSI C rather than K&R for "main". Suggest
6184 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
6185 and suggest yy_switch_to_buffer.
6187 2003-05-05 Paul Eggert <eggert@twinsun.com>
6189 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
6190 C89. This avoids a diagnostic on compilers that define __STDC__
6191 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
6192 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
6194 2003-05-03 Paul Eggert <eggert@twinsun.com>
6196 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
6197 Do not overrun array bounds.
6198 This should fix a bug reported today by Olatunji Oluwabukunmi in
6199 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
6201 2003-04-29 Akim Demaille <akim@epita.fr>
6203 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
6204 * src/getargs.c, src/getargs.h: here, as bool, not int.
6205 (nondeterministic_parser): New.
6206 * src/parse-gram.y, src/scan-gram.l: Support
6207 %nondeterministic-parser.
6208 * src/output.c (prepare): Use nondeterministic_parser instead
6209 of glr_parser where appropriate.
6210 * src/tables.c (conflict_row, action_row, save_row)
6211 (token_actions, token_actions, pack_vector): Ditto.
6213 2003-04-29 Akim Demaille <akim@epita.fr>
6215 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
6217 2003-04-29 Akim Demaille <akim@epita.fr>
6219 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
6220 with %pure-parser and %locations to exercise the patch from Yakov
6223 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
6225 * data/yacc.c: (b4_lex_param): Corrected for the case where
6226 %lex-param is provided and %pure-parser isn't.
6228 2003-04-27 Paul Eggert <eggert@twinsun.com>
6230 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
6231 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
6232 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
6233 if it is not defined.
6234 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
6236 2003-04-26 Paul Eggert <eggert@twinsun.com>
6238 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
6239 Declare to be of type suitable for the ninf value itself, not of
6240 type suitable for the corresponding table, since the latter might
6241 be unsigned but the ninf value might be negative. This fixes a
6242 bug reported by Alexandre Duret-Lutz in
6243 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
6245 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
6246 invokes it. We shouldn't invoke it twice because it will attempt
6247 to put error.o in the archive twice. This fixes a glitch reported
6248 by Martin Mokrejs in
6249 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
6251 2003-04-21 Paul Eggert <eggert@twinsun.com>
6253 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
6256 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
6258 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
6259 Fix obvious typo that results in uncompilable GLR parsers
6260 when both %pure-parser and %locations are used. (trivial change)
6262 2003-04-17 Paul Eggert <eggert@twinsun.com>
6264 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
6265 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
6266 Do not insert the expected token via unput, as this runs afoul
6267 of a POSIX-compatibility bug in flex 2.5.31.
6268 All uses changed to BEGIN the parent state,
6269 since we no longer insert the expected token via unput.
6270 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
6271 that is no longer emitted after the above change.
6273 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
6274 the first one. This change is from Paul Hilfinger, and it fixes
6275 regression reported by Werner Lemberg in
6276 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
6278 (resolve_sr_conflict): Don't invoke state_errs_set
6279 unless one or more tokens have been explicitly made errors.
6280 Otherwise, the above change causes Bison to abort.
6282 * tests/existing.at (GNU pic Grammar): New test case, taken from
6285 2003-03-31 Akim Demaille <akim@epita.fr>
6287 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
6289 2003-03-31 Akim Demaille <akim@epita.fr>
6291 * src/output.c (prepare_symbols): Avoid trailing spaces in the
6294 2003-03-31 Akim Demaille <akim@epita.fr>
6296 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
6297 From Paul Hilfinger.
6299 2003-03-29 Akim Demaille <akim@epita.fr>
6301 * m4/error.m4: Do not put under dynamic conditions some code which
6302 expansion is under static control.
6304 2003-03-29 Akim Demaille <akim@epita.fr>
6306 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
6308 2003-03-29 Akim Demaille <akim@epita.fr>
6310 * doc/bison.texinfo (Strings are Destroyed): New.
6312 2003-03-13 Paul Eggert <eggert@twinsun.com>
6314 * .cvsignore: Add configure.lineno.
6315 * src/.cvsignore: Add yacc.
6316 * tests/.cvsignore: Add testsuite.log.
6317 * doc/fdl.texi: Sync with latest FSF version.
6319 2003-03-12 Paul Eggert <eggert@twinsun.com>
6321 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
6322 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
6323 cursor, instead of leaving it undefined. This fixes a bug
6324 reported by Tim Van Holder in
6325 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
6326 * tests/input.at (Torturing the Scanner): Test the scanner on
6327 an empty input file, which was Tim Van Holder's test case.
6329 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
6330 <sys/resource.h> can be included, include sys/time.h and
6331 sys/times.h first, if available. This works around the SunOS
6332 4.1.4 porting bug reported by Bruce Becker in
6333 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
6335 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
6336 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
6339 Merge changes from gnulib. This was prompted because the CVS
6340 snapshot didn't build on Solaris 7 due to strnlen problems.
6342 These changes need to be merged back into gnulib:
6343 * lib/hash.c: Include <stdbool.h> unconditionally.
6344 * m4/onceonly.m4 (m4_quote): New macro.
6345 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
6346 Quote AC_FOREACH variable-expansions properly.
6347 The 2003-01-03 obstack.h change also needs merging.
6348 {end of changes requiring merging}
6350 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
6351 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
6352 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
6353 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
6354 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
6355 New files, imported from gnulib.
6356 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
6359 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
6360 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
6363 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
6365 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
6366 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
6367 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
6368 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
6369 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
6370 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
6371 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
6372 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
6373 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
6374 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
6375 (jm_PREREQ_ARGMATCH): Remove.
6376 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
6377 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
6379 * src/system.h: Include <stdbool.h> unconditionally.
6381 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
6382 assuming at least C89 in the bitset code for some time now.
6384 2003-03-03 Akim Demaille <akim@epita.fr>
6388 2003-03-02 Akim Demaille <akim@epita.fr>
6390 * doc/bison.texinfo (Table of Symbols): Reactivate the
6391 documentation for %lex-param, and %parse-param.
6393 2003-03-02 Akim Demaille <akim@epita.fr>
6395 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
6396 generate verbose error messages.
6397 Use the number of tokens as an upper bound in yytname, as it
6398 cannot be a non terminal.
6400 2003-03-02 Akim Demaille <akim@epita.fr>
6402 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
6405 2003-03-02 Akim Demaille <akim@epita.fr>
6407 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
6408 Use them to exercise yycheck overrun.
6409 Based on Andrew Suffield's grammar.
6411 2003-03-02 Akim Demaille <akim@epita.fr>
6413 Create tests/local.at for Bison generic testing macros.
6415 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
6416 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
6418 * tests/calc.at (AT_CHECK_CALC): Adjust.
6419 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
6420 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
6421 * tests/local.at: here.
6422 (AT_COMPILE_CXX): Tags the tests using it as c++.
6423 Ignore the test if CXX is not functional.
6425 2003-03-01 Paul Eggert <eggert@twinsun.com>
6427 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
6428 not loc->end, since loc->end might contain garbage and this leads
6429 to undefined behavior on some platforms.
6430 (id_loc, token_start): Use (IF_LINTed) initial values that do not
6431 depend on *loc, so that the reader doesn't give the the false
6432 impression that *loc is initialized.
6433 (<INITIAL>"%%"): Do not bother setting code_start, since its value
6434 does not survive the return.
6436 2003-03-01 Akim Demaille <akim@epita.fr>
6438 * src/scan-gram.l (code_start): Always initialize it when entering
6439 into yylex, as SC_EPILOGUE is activated *before* the corresponding
6440 yylex invocation. An alternative would be making it static, but
6441 then it starts with the second %%'s beginning, instead of its end.
6443 2003-02-28 Paul Eggert <eggert@twinsun.com>
6445 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
6446 around a UnixWare 7.1.1 porting bug reported by John Hughes in
6447 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
6449 2003-02-26 Paul Eggert <eggert@twinsun.com>
6451 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
6452 Remove Sequent/Pyramid discussion (nobody uses them any more).
6453 Merge VMS and MS-DOS discussion; these ports may well be dead
6454 but let's keep mentioning them for now. Put <> around email
6455 addresses. Add copyright notice.
6457 2003-02-24 Paul Eggert <eggert@twinsun.com>
6459 * data/glr.c (yy_reduce_print): yylineno -> yylno,
6460 to avoid collision with flex use of yylineno.
6461 Problem reported by Bruce Lilly in
6462 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
6463 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
6464 * data/yacc.c (yy_reduce_print): Likewise.

6468 2003-02-21 Akim Demaille <akim@epita.fr>
6470 * data/lalr1.cc: Use temporary variables instead of casts to
6471 change integer types.
6472 Suggested by Paul Eggert.
6474 2003-02-21 Akim Demaille <akim@epita.fr>
6476 * doc/bison.texinfo: Use "location" consistently to refer to @n,
6477 to avoid confusions with lalr1.cc's notion of Position.
6478 Suggested by Paul Eggert.
6480 2003-02-20 Akim Demaille <akim@epita.fr>
6482 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
6483 before initial_columns.
6484 (location.hh): Use consistent variable names when defining the
6486 Use "last" so that we subtract from Positions, not from unsigned.
6488 2003-02-20 Akim Demaille <akim@epita.fr>
6490 * data/lalr1.cc (position.hh): New subfile, including the extended
6491 and Doxygen'ed documentation of class Position.
6492 (location.hh): Use it.

6494 With the help of Benoit Perrot.
6496 2003-02-20 Akim Demaille <akim@epita.fr>
6498 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
6500 Redefine AT_YYERROR_SEES_LOC_IF using it.
6501 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
6503 Don't use the location in yy::Parser::error_ and
6504 yy::Parser::print_ when not %locations.
6505 Activate more lalr1.cc tests.
6507 2003-02-19 Akim Demaille <akim@epita.fr>
6509 * data/lalr1.cc: When displaying a line number, be sure to make it
6512 2003-02-19 Akim Demaille <akim@epita.fr>
6514 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
6516 (YYABORT, YYACCEPT, YYERROR): New.
6517 * tests/calc.at: Renable the lalr1.cc test.
6519 2003-02-19 Akim Demaille <akim@epita.fr>
6521 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
6522 error recovery, mixing with/without pops and discarding of the
6525 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
6527 2003-02-17 Paul Eggert <eggert@twinsun.com>
6529 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
6530 * tests/testsuite.at (AT_COMPILE): Use them.
6531 This fixes the testsuite problem reported by Robert Lentz in
6532 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
6534 2003-02-12 Paul Eggert <eggert@twinsun.com>
6536 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
6537 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
6538 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
6539 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
6540 Check for malloc failure, for consistency with yacc.c.
6541 (yytname_size): Remove, for consistency with yacc.c.
6543 The bug still remains in data/lalr1.cc, as I didn't have time
6546 2003-02-06 Akim Demaille <akim@epita.fr>
6548 * configure.ac (GXX): Rename as...
6549 (CXX): this, to keep the original Autoconf semantics.
6551 * data/lalr1.cc: Fix b4_copyright invocations.
6552 If YYDEBUG is not defined, don't depend upon name_ being defined.
6553 (location.hh): Include string and iostream.
6554 (Position::filename): New member.
6555 (Position::Position ()): New.
6556 (operator<< (Position)): New.

6564 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
6565 locations in a more synthetic way.
6566 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
6568 Adjust the C locations to match those from Emacs: first column is
6570 Change all the expected results.
6571 Conform to the GCS: simplify the locations when applicable.
6572 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
6573 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
6574 these CPP macros with the m4 macros new defined by...
6575 (AT_CHECK_PUSHDEFS): this, i.e.:
6576 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)

6579 (AT_CHECK_POPDEFS): Undefine them.
6580 (AT_CHECK_CALC_LALR1_CC): New.
6581 Use it for the first lalr1.cc test.
6583 2003-02-04 Akim Demaille <akim@epita.fr>
6585 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
6586 Location as is defined.
6588 2003-02-04 Akim Demaille <akim@epita.fr>
6590 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
6591 name_ being defined.
6593 2003-02-03 Paul Eggert <eggert@twinsun.com>
6595 * src/gram.h (start_symbol): Remove unused decl.
6597 Use more-consistent naming conventions for local vars.
6599 * src/derives.c (derives_compute): Change type of local var from
6601 * src/gram.c (grammar_rules_partial_print): Likewise.
6602 * src/print.c (print_core): Likewise.
6603 * src/reduce.c (reduce_grammar_tables): Likewise.
6605 * src/gram.c (grammar_dump): Change name of item_number *
6606 local var from r to rp.
6607 * src/nullable.c (nullable_compute): Likewise.
6609 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
6611 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
6612 for symbol or symbol_number var.
6613 * src/reader.c (grammar_start_symbol_set): Likewise.
6614 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
6616 * src/state.c (transitions_to): Likewise.
6617 * src/state.h: Likewise.
6618 * src/tables.c (symbol_number_to_vector_number): Likewise.
6620 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
6623 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
6626 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
6629 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
6630 Use str, not s, for char * var. Use ch, not c, for character var.
6631 Use size for size var.
6633 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
6635 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
6637 * src/uniqstr.h: Likewise.
6639 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
6640 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
6641 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
6642 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
6643 param to have same name as that of enum, so that we don't use
6644 "s" to stand for a non-state.
6646 2003-02-02 Akim Demaille <akim@epita.fr>
6648 * src/scan-skel.l: Scan more than one inert character per yylex
6651 2003-02-01 Paul Eggert <eggert@twinsun.com>
6655 * po/LINGUAS: Add ms.
6657 2003-01-30 Akim Demaille <akim@epita.fr>
6659 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
6661 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
6663 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
6666 Changes in response to error report by S. Eken: GLR mode does not
6667 handle negative $ indices or $ indices in embedded rules correctly.
6668 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
6670 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
6671 (b4_rhs_location): Ditto.
6672 (yyfill): New function to copy from stack tree into array
6674 (yyuserAction): Modify to allow incremental move of semantic values
6675 to rhs array when in GLR mode.
6676 Define YYFILL to use in user-defined actions to fill semantic array
6678 Remove dummy use of yystack, as there is now a guaranteed use.
6679 (yydoAction): Modify to allow incremental move of semantic values
6680 to rhs array when in GLR mode.
6681 (yyresolveAction): Ditto.
6682 (yyglrShiftDefer): Update comment.
6683 (yyresolveStates): Use X == NULL for pointers, not !X.
6684 (yyglrReduce): Ditto.
6687 * tests/glr-regr1.at: Rename to ...
6688 * tests/glr-regression.at: Add new regression test for the problems
6689 described above (adapted from S. Eken).
6690 Update copyright notice.
6691 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
6692 * tests/Makefile.am: Ditto.
6694 2003-01-28 Paul Eggert <eggert@twinsun.com>
6696 * data/lalr1.cc: Do not use @output_header_name@ unless
6697 b4_defines_flag is set. This fixes two bugs reported by
6699 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
6700 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
6702 2003-01-21 Paul Eggert <eggert@twinsun.com>
6704 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
6705 we don't need to worry about yyerrlab1 being reported as an
6706 "unused label" by non-GCC C compilers. The downside is that if
6707 locations are used then a couple of statements are duplicated each
6708 time YYERROR is invoked, but the upside is that the warnings
6710 (yyerrlab1): Move code to YERROR.
6711 (yyerrlab2): Remove. Change uses back to yyerrlab1.
6712 This reverts some of the 2002-12-27 change.
6714 2003-01-17 Paul Eggert <eggert@twinsun.com>
6716 * src/output.c (symbol_printers_output): Fix typo that led
6717 to core dump. Problem reported by Antonio Rus in
6718 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
6720 2003-01-13 Akim Demaille <akim@epita.fr>,
6721 Quoc Peyrot <chojin@lrde.epita.fr>,
6722 Robert Anisko <anisko_r@lrde.epita.fr>
6724 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
6725 when the stacks contain one element, as the loop would otherwise
6726 free the last state, and then use the top state (the one we just
6727 popped). This means that the initial elements will not be freed
6728 explicitly, as is the case in yacc.c; it is not a problem, as
6729 these elements have fake values.
6731 2003-01-11 Paul Eggert <eggert@twinsun.com>
6733 * NEWS: %expect-violations are now just warnings, reverting
6734 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
6735 bootstrapping problem reported by Matthias Klose; see
6736 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
6737 * src/conflicts.c (conflicts_print): Likewise.
6738 * tests/conflicts.at (%expect not enough, %expect too much,
6739 %expect with reduce conflicts): Likewise.
6740 * doc/bison.texinfo (Expect Decl): Document this. Also mention
6741 that the warning is enabled if the number of conflicts changes
6742 (not necessarily increases).
6744 * src/getargs.c (version): Update copyright year.
6746 2003-01-09 Akim Demaille <akim@epita.fr>
6748 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
6750 2003-01-08 Paul Eggert <eggert@twinsun.com>
6752 * Makefile.maint (WGETFLAGS):
6753 New macro, containing "-C off" to disable proxy caches.
6754 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
6755 (rel-check): Use $(WGET) instead of wget.
6757 2003-01-06 Paul Eggert <eggert@twinsun.com>
6759 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
6760 the GLR paper of Scott, Johnstone and Hussain.
6762 2003-01-04 Paul Eggert <eggert@twinsun.com>
6764 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
6765 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
6766 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
6767 (EXTRA_LIBRARIES): New var, for liby.a.
6768 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
6769 (EXTRA_SCRIPTS): New var, for yacc.
6771 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
6772 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
6773 Problem reported by Nelson H. F. Beebe.
6775 2003-01-03 Paul Eggert <eggert@twinsun.com>
6777 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
6778 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
6779 when compiling Bison 1.875's `bitset bset = obstack_alloc
6780 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
6782 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
6783 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
6784 grow to a huge size with typical invocation.
6786 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
6787 Use the pattern recommended by Autoconf 2.57, except also protect
6788 against double-definition.
6789 * src/system.h: Likewise.
6790 Portability issues reported by Nelson H. F. Beebe.
6792 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
6793 All uses changed. Provide a definition in both C and C++.
6794 (yytrue, yyfalse): Define even if defined (__cplusplus).
6796 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
6797 Reported by Nelson H. F. Beebe.
6799 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
6801 2003-01-02 Paul Eggert <eggert@twinsun.com>
6803 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
6804 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
6805 Bug reported by Nelson H. F. Beebe.
6807 2003-01-01 Paul Eggert <eggert@twinsun.com>
6811 2002-12-30 Paul Eggert <eggert@twinsun.com>
6813 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
6815 (<INITIAL>","): Here. This causes stray "," to be treated
6818 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
6819 last brace in braced code when not in Yacc mode, for compatibility
6820 with Bison 1.35. This resurrects the 2001-12-15 patch to
6823 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
6824 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
6826 2002-12-28 Paul Eggert <eggert@twinsun.com>
6828 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
6829 that of SYM's type. This fixes Debian bug 168069, reported by
6832 2002-12-28 Paul Eggert <eggert@twinsun.com>
6836 Switch back to the Yacc style of conflict reports, undoing some
6837 of the 2002-07-30 change.
6838 * doc/bison.texinfo (Understanding): Use Yacc style for
6839 conflict reports. Also, use new way of locating rules.
6840 * src/conflicts.c (conflict_report):
6841 Renamed from conflict_report_yacc, removing the old
6842 'conflict_report'. Translate the entire conflict report at once,
6843 so that we don't assume that "," has the same interpretation in
6845 (conflicts_output): Use Yacc-style conflict report for each state,
6846 instead of our more-complicated style.
6847 (conflicts_print): Use Yacc-style conflict report, except print
6848 the input file name when not emulating Yacc.
6849 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
6850 Conflicted Reduction, %expect not enough, %expect too much,
6851 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
6852 * tests/existing.at (GNU Cim Grammar): Likewise.
6853 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
6855 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
6856 fatal): Don't invoke fflush; it's not needed and it might even be
6857 harmful for stdout, as stdout might not be open.
6858 * src/reduce.c (reduce_print): Likewise.
6860 2002-12-27 Paul Eggert <eggert@twinsun.com>
6862 Fix a bug where error locations were not being recorded correctly.
6863 This problem was originally reported by Paul Hilfinger in
6864 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
6866 * data/yacc.c (yyparse): New local var yylerrsp, to record the
6867 top of the location stack's error locations.
6868 (yyerrlab): Set it. When discarding a token, push its location
6869 onto yylerrsp so that we don't lose track of the error's end.
6870 (yyerrlab1): Now is only the target of YYERROR, so that we can
6871 properly record the location of the action that failed. For GCC
6872 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
6873 GCC warning about yyerrlab1 being unused if YYERROR is unused.
6874 (yyerrlab2): New label, which yyerrlab now falls through to.
6875 Compute the error's location by applying YYLLOC_DEFAULT to
6876 the locations of all the symbols that went into the error.
6877 * doc/bison.texinfo (Location Default Action): Mention that
6878 YYLLOC_DEFAULT is also invoked for syntax errors.
6879 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
6880 Error locations include the locations of all the tokens that were
6881 discarded, not just the last token.
6883 2002-12-26 Paul Eggert <eggert@twinsun.com>
6885 * src/files.c: Include quote.h.
6886 (compute_output_file_names): Warn if we detect conflicting
6887 outputs to the same file. This should catch the misunderstanding
6888 exemplified by Debian Bug 165349, reported by Bruce Stephens..
6890 * src/conflicts.c (conflicts_print): If the user specifies
6891 "%expect N", report an error if there are any reduce/reduce
6892 conflicts. This is what the manual says should happen.
6893 This fixes Debian bug 130890, reported by Anthony DeRobertis.
6894 * tests/conflicts.at (%expect with reduce conflicts): New test.
6896 Don't use m4_include on relative file names, as it doesn't work as
6897 desired if there happens to be a file with that name under ".".
6899 * m4sugar/version.m4: Remove; it was included but it wasn't used.
6900 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
6901 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
6902 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
6903 * src/output.c (output_skeleton): Use full path names when
6904 specifying a file to include; don't rely on include path, as
6905 it's unreliable when the working file contains a file with
6908 2002-12-25 Paul Eggert <eggert@twinsun.com>
6910 Remove obsolete references to bison.simple and bison.hairy.
6911 Problem mentioned by Aubin Mahe in
6912 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
6913 * data/glr.c: Comment fix.
6914 * doc/bison.1: Remove references. Also, mention "yacc".
6916 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
6919 * src/parse-gram.y (declaration): Use enum "report_states" rather
6920 than its numeric value 1.
6922 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
6923 opening a new one. This fixes Debian bug 165349, reported by
6926 2002-12-24 Paul Eggert <eggert@twinsun.com>
6930 * Makefile.maint (cvs-update): Don't assume that the shell
6931 supports $(...), as Solaris sh doesn't.
6933 * src/parse-gram.y (lloc_default): Remove test for empty
6934 nonterminals at the end, since it didn't change the result.

6938 If the user does not define YYSTYPE as a macro, Bison now declares it
6939 using typedef instead of defining it as a macro. POSIX requires this.
6940 For consistency, YYLTYPE is also declared instead of defined.
6942 %union directives can now have a tag before the `{', e.g., the
6943 directive `%union foo {...}' now generates the C code
6944 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
6945 The default union tag is `YYSTYPE', for compatibility with Solaris 9
6946 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
6947 instead of `yyltype'.
6949 `yystype' and `yyltype' are now obsolescent macros instead of being
6950 typedefs or tags; they are no longer documented and will be
6951 withdrawn in a future release.
6953 * data/glr.c (b4_location_type): Remove.
6954 (YYSTYPE): Renamed from yystype.
6955 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
6956 (struct YYLTYPE): Renamed from struct yyltype.
6957 (YYLTYPE): Renamed from yyltype.
6958 (yyltype, yystype): New (and obsolescent) macros,
6959 for backward compatibility.
6960 * data/yacc.c: Likewise.
6962 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
6963 does not specify a union tag. This is for compatibility with
6966 * src/parse-gram.y (add_param): 2nd arg is now char * not char
6967 const *, since it is now modified by stripping surrounding { }.
6968 (current_braced_code): Remove.
6969 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
6970 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
6971 trailing " {...}". Now of type <chars>.
6972 (grammar_declaration): Adjust to bundled tokens.
6973 (code_content): Remove; stripping is now done by add_param.
6974 (print_token_value): Print contents of bundled tokens.
6975 (token_name): New function.
6977 * src/reader.h (braced_code, current_braced_code): Remove.
6978 (token_name): New decl.
6980 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
6981 token_type, not braced_code code_kind. All uses changed.
6982 (SC_PRE_CODE): New state, for scanning after a keyword that
6983 has (or usually has) an immediately-following braced code.
6984 (token_type): New local var, to keep track of which token type
6985 to return when scanning braced code.
6986 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
6987 <INITIAL>"%parse-param", <INITIAL>"%printer",
6988 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
6989 instead of returning a token type immediately.
6990 (<INITIAL>"{"): Set token type.
6991 (<SC_BRACED_CODE>"}"): Use it.
6992 (handle_action_dollar, handle_action_at): Now returns bool
6993 indicating success. Fail if ! current_rule; this prevents a core dump.
6994 (handle_symbol_code_dollar, handle_symbol_code_at):
6995 Remove; merge body into caller.
6996 (handle_dollar, handle_at): Complain in invalid contexts.
6998 * NEWS, doc/bison.texinfo: Document the above.
6999 * NEWS: Fix years and program names in copyright notice.
7001 2002-12-17 Paul Eggert <eggert@twinsun.com>
7003 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
7004 Reporting, Table of Symbols): Omit mentions of %lex-param and
7005 %parse-param from the documentation for now.
7007 2002-12-15 Paul Eggert <eggert@twinsun.com>
7009 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
7010 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
7011 lookahead symbol, and which sets yychar in parser actions) and it
7012 disagreed with the Bison documentation. Bug
7013 reported by Andrew Walrond.
7015 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
7016 as the caller now does that.
7017 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
7018 (YYEMPTY): Parenthesize right hand side, since others use it.
7019 (yyparse): Don't assume that our generated code is the only code
7022 2002-12-13 Paul Eggert <eggert@twinsun.com>
7026 POSIX requires a "yacc" command.
7027 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
7028 (MOSTLYCLEANFILES): Add yacc.
7030 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
7031 as an alias for bison y.
7033 * po/LINGUAS: Add da.
7035 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
7036 problem with latest <getopt.h>.
7037 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
7039 * doc/fdl.texi: Upgrade to 1.2.
7040 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
7041 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
7042 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
7044 * config/install-sh: Sync with autotools.
7046 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
7047 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
7048 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
7049 locations are requested.
7050 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
7051 locations are requested.
7053 2002-12-12 Paul Eggert <eggert@twinsun.com>
7055 Remove unportable casts and storage allocation tricks.
7056 While we're at it, remove almost all casts, since they
7057 usually aren't needed and are a sign of trouble.
7059 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
7061 * src/derives.c (derives_compute): Do not subtract NTOKENS from
7062 the pointer DSET returned by malloc; this isn't portable.
7063 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
7064 Similarly for DERIVES.
7065 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
7066 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
7067 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
7069 * src/derives.c (derives_compute): Do not bother invoking
7070 int_of_rule_number, since rule numbers are integers.
7072 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
7073 rather than XMALLOC (char, N).
7075 * src/files.c (filename_split): Rewrite to avoid cast.

7080 Now inline functions rather than macros, to avoid casts.
7081 * src/state.h (state_number_as_int): Likewise.
7082 * src/tables.c (state_number_to_vector_number,
7083 symbol_number_to_vector_number): Likewise.
7085 * src/gram.h (int_of_rule_number): Remove; no longer used.
7087 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
7088 since the resulting storage is always stored into.
7090 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
7093 * src/muscle_tab.c (muscle_m4_output):
7094 Now inline. Return bool, not int.
7095 * src/state.c (state_compare): Likewise.

7107 hash_symbol_hasher): Likewise.
7108 * src/uniqstr.c (uniqstr_print_processor): Likewise.
7109 * src/muscle_tab.c (muscles_m4_output):
7110 Use new functions instead of casting old functions unportably.
7111 * src/state.c (state_hash_new): Likewise.
7112 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
7113 symbols_token_translations_init):
7115 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
7117 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
7118 var instead of casting to long, to avoid casts.
7119 (prepare_states): Use MALLOC rather than alloca, so that we don't
7120 have to worry about alloca.
7121 * src/state.c (state_hash_lookup): Likewise.
7123 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
7124 local var instead of casting to unsigned char, to avoid casts.

7127 STATE_ALLOC): Remove.
7128 (transitions_new, errs_new, reductions_new, state_new): Use malloc
7129 rather than calloc, and use offsetof to avoid allocating slightly
7131 (state_new): Initialize all members.
7133 * src/state.c (state_hash): Use unsigned accumulator, not signed.
7135 * src/symtab.c (symbol_free): Remove; unused.
7136 (symbol_get): Remove cast in lhs of assignment.
7137 (symbols_do): Now static. Accept generic arguments, not
7138 hashing-related ones.
7140 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
7141 (symbol_processor): Remove.
7142 (symbols_do): Remove decl; now static.
7144 * src/system.h (alloca): Remove; decl no longer needed.
7145 (<stddef.h>): Include, for offsetof.
7146 (<inttypes.>, <stdint.h>): Include if available.
7147 (uintptr_t): New type, if system lacks it.
7148 (CALLOC, MALLOC, REALLOC): New macros.
7149 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
7152 * src/tables.c (table_size): Now int, to pacify GCC.
7153 (table_grow, table_ninf_remap): Use signed table size.
7154 (save_row): Don't bother initializing locals when not needed.
7155 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
7156 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
7158 * src/vcg.h: Correct misspellings.
7160 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
7163 * src/getargs.c (getargs): Don't assume EOF == -1.
7165 2002-12-09 Paul Eggert <eggert@twinsun.com>
7167 Change identifier spellings to avoid collisions with names
7168 that are reserved by POSIX.
7170 Don't use names ending in _t, since POSIX reserves them.
7171 For consistency, remove _e and _s endings -- they're weren't
7172 needed to remove ambiguity. All uses changed.
7173 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
7174 turn was just renamed from struniq_t.
7175 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
7176 which in turn was just renamed from struniq_processor_t.
7177 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which
7178 in turn was renamed from hash_compare_struniq_t.

7247 * tests/input.at (Torturing the Scanner): Rename value_t -> value,
7248 value_t_as_yystype -> value_as_yystype.
7250 Don't include <errno.h> in the mainstream code, since it
7251 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
7252 * lib/get-errno.c, lib/get-errno.h: New files.
7253 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
7255 * src/files.c (xfopen, xfclose): Use get_errno instead of errno.

7263 (TAB_EXT): Renamed from EXT_TAB.
7264 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
7266 Avoid str[a-z]*, since <string.h> reserves that name space.

7268 likewise for "STRUNIQ" and "UNIQSTR".
7269 * src/uniqstr.c: Renamed from src/struniq.c.
7270 * src/uniqstr.h: Renamed from src/struniq.h.
7271 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.

7292 (BASE_MAXIMUM): Renamed from BASE_MAX.
7293 (BASE_MINIMUM): Renamed from BASE_MIN.
7294 (ACTION_MAX): Remove; unused.
7295 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
7296 Unnecessary casts removed from above defines.
7299 Fix misspelling in names.
7300 * src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e.
7301 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
7305 * lib/timevar.c (timevar_report): Renamed from time_report,
7306 for consistency with other names.
7307 * lib/timevar.h (timevar_report): New decl.
7308 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
7311 Sort include-file uses.
7313 Reorder all include files under src to be in the order "system.h".
7314 then the ../lib include files in angle brackets (alphabetized),
7315 then the . include files in double-quotes (alphabetized). Fix
7316 dependency breakages encountered in this process, as follows:
7317 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
7318 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
7319 * src/state.h: Include "symtab.h".
7321 2002-12-08 Paul Eggert <eggert@twinsun.com>
7323 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
7324 since this causes problems when __file__ contains character
7325 sequences like "@" that are treated specially by src/scan-skel.l.
7326 Instead, just use the file's basename. This fixes the bug
7327 reported by Martin Mokrejs in
7328 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
7330 2002-12-06 Paul Eggert <eggert@twinsun.com>
7332 Add support for rules that do not have trailing semicolons, as
7333 POSIX requires. Improve the quality of locations in Bison
7336 * src/location.c: Include <quotearg.h>.
7337 (empty_location): Now const.
7338 (location_print): New function. Follow the recommendation of the
7339 GNU Coding Standards for locations that span file boundaries.
7340 * src/location.h: Do not include <quotearg.h>; no longer needed.
7341 (boundary): New type.
7342 (location_t): Use it. This allows locations to span file boundaries.
7343 All member uses changed: file -> start.file or end.file (as needed),
7344 first_line -> start.line, first_column -> start.column,
7345 last_line -> end.line, last_column -> end.column.
7346 (equal_boundaries): New function.
7347 (LOCATION_RESET, LOCATION_STEP): Remove.
7348 (LOCATION_PRINT): Remove. All callers changed to use location_print.
7349 (empty_location): Now const.
7350 (location_print): New decl.
7351 * src/parse-gram.y (lloc_default): New function, which handles
7352 empty locations more accurately.
7353 (YYLLOC_DEFAULT): Use it.
7354 (%token COLON): Remove.
7355 (%token ID_COLON): New token.
7357 (declarations, rules): Remove trailing semicolon.
7358 (declaration, rules_or_grammar_declaration):

7361 (rules_or_grammar_declaration): Remove trailing semicolon.
7362 (semi_colon.opt): Remove.
7363 * src/reader.h: Include location.h.
7364 (scanner_cursor): New decl.
7365 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
7367 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
7369 (STEP): Remove. No longer needed, now that adjust_location does
7370 the work. All uses removed.
7371 (scanner_cursor): New var.
7372 (adjust_location): Renamed from extend_location. It now sets
7373 *loc and adjusts the scanner cursor. All uses changed.
7374 Don't bother testing for CR.
7375 (handle_syncline): Remove location arg; now updates scanner cursor.
7376 All callers changed.
7377 (unexpected_end_of_file): Now accepts start boundary of token or
7378 comment, not location. All callers changed. Update scanner cursor,
7380 (SC_AFTER_IDENTIFIER): New state.
7381 (context_state): Renamed from c_context. All uses changed.
7382 (id_loc, code_start, token_start): New local vars.
7383 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
7384 processing of Yacc white space and equivalents here.
7385 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
7386 instead of returning ID immediately, since we need to search for
7388 (<INITIAL>"'", "\""): Save token_start.
7389 (<INITIAL>"%{", "{", "%%"): Save code_start.
7390 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
7391 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
7392 BEGIN context_state at end, not INITIAL.
7393 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
7394 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
7395 Return correct token start.
7396 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
7397 the start of a character, string or multiline comment is found.
7398 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
7399 Reduction): Adjust reported locations to match the more-precise
7400 results now expected.
7401 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
7402 * tests/reduce.at (Useless Rules, Reduced Automaton,
7403 Underivable Rules): Likewise.
7404 * tests/regression.at (Invalid inputs): No longer `expecting ";"
7405 or "|"' now that so many other tokens are allowed by the new grammar.
7407 * src/complain.h (current_file): Remove duplicate decl;
7408 current_file is now owned by files.h.
7409 * src/complain.c, src/scan-gram.l: Include files.h.
7411 2002-12-06 Paul Eggert <eggert@twinsun.com>
7413 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
7414 promotes to int; it might be unsigned int.
7415 * data/yacc.c (yy_reduce_print): Likewise.
7417 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
7418 be #defined in the prologue, not in the Bison declarations.
7419 This fixes Debian Bug 102878, reported by Shaul Karl.
7421 2002-12-02 Paul Eggert <eggert@twinsun.com>
7423 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
7424 * lib/strtoul.c: New file, from gnulib.
7425 This fixes a porting bug reported by Peter Klein in
7426 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
7428 2002-11-30 Paul Eggert <eggert@twinsun.com>
7430 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
7431 and put only a forward declaration in the prologue. This is for
7432 consistency with the other scanner helper functions.
7434 Type clashes now generate warnings, not errors, since it
7435 appears that POSIX may allow some grammars with type clashes.
7436 * src/reader.c (grammar_current_rule_check): Warn about
7437 type clashes instead of complaining.
7438 * tests/input.at (Type Clashes): Expect warnings, not complaints.
7440 Add Yacc library, since POSIX requires it.
7441 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
7442 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
7443 * lib/main.c, lib/yyerror.c: New files.
7445 gram_error can be static; it need not be extern.
7446 * src/reader.h (gram_error): Remove decl.
7447 * src/parse-gram.y (gram_error): Now static. Add static decl.
7448 (print_token_value): Omit parameter names from forward decl,
7451 2002-11-29 Paul Eggert <eggert@twinsun.com>
7453 * doc/bison.texinfo: Emphasize that yylex and yyerror must
7454 be declared before being used. E.g., one should typically
7455 declare them in the prologue. Use GNU coding style in examples.
7456 Put "const" consistently after the type it modifies. Mention
7457 that C99 supports "inline". Mention that yyerror traditionally
7460 %parse-param and %lex-param now take just one argument, the
7461 declaration; the argument name is deduced from the declaration.
7463 * doc/bison.texinfo (Parser Function, Pure Calling, Error
7464 Reporting, Table of Symbols): Document this.
7465 * src/parse-gram.y (add_param): New function.
7467 (declaration): Implement new rule for %parse-param and %lex-param.
7468 * src/scan-gram.l: "," now elicits a warning, rather than being
7469 a token; this is more compatible with byacc.
7470 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
7472 2002-11-27 Paul Eggert <eggert@twinsun.com>
7474 Rename identifiers to avoid real and potential collisions.
7476 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
7477 to avoid collision with lex macro described by Bruce Lilly in
7478 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
7479 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
7480 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
7481 * src/parse-gram.y (print_token_value): Renamed from yyprint.
7483 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
7484 The name "yycontrol" violates the name space rules, and this stuff
7485 wasn't being used anyway.
7486 (input): Remove action; this stuff wasn't being used.
7487 (gram_error): Rename local variable yylloc -> loc.
7488 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
7489 (YY_DECL): Don't use "yy" at start of local variables.
7490 All uses changed, e.g., yylloc -> loc.
7491 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
7492 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
7493 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
7494 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
7496 * src/parse-gram.y (gram_error): loc is now const *.
7497 * src/reader.h (gram_error): Likewise.
7499 2002-11-24 Paul Eggert <eggert@twinsun.com>
7503 * tests/actions.at (Actions after errors): Use an output format
7504 more similar to that of the Printers and Destructors test.
7505 Test the position of the ';' token too.
7506 (Printers and Destructors): Likewise.
7507 (Printers and Destructors: %glr-parser): Remove for now, to avoid
7508 unnecessarily alarming people when the test fails.
7510 * data/yacc.c (yyerrlab1): Move this label down, so that the
7511 parser does not discard the lookahead token if the user code
7512 invokes YYERROR. This change is required for POSIX conformance.
7514 * lib/error.c: Sync with gnulib.
7516 2002-11-22 Paul Eggert <eggert@twinsun.com>
7518 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
7519 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
7520 * lib/xmalloc.c: Likewise.
7522 2002-11-20 Paul Eggert <eggert@twinsun.com>
7524 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
7526 2002-11-20 Paul Eggert <eggert@twinsun.com>
7528 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
7529 should use `if (! x) abort ();' rather than `assert (x);', and
7530 anyway it's one less thing to worry about configuring.
7532 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
7533 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
7534 and replace all instances of assert with abort.
7535 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
7536 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
7538 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
7539 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
7540 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
7541 hash_find_entry, hash_rehash, hash_insert): Likewise.
7542 * src/conflicts.c (resolve_sr_conflict): Likewise.
7543 * src/lalr.c (set_goto_map, map_goto): Likewise.
7544 * src/nullable.c (nullable_compute): Likewise.
7545 * src/output.c (prepare_rules, token_definitions_output): Likewise.
7546 * src/reader.c (packgram, reader): Likewise.
7547 * src/state.c (state_new, state_free, state_transitions_set,
7548 state_reduction_find): Likewise.
7549 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
7550 symbol_pack): Likewise.
7551 * src/tables.c (conflict_row, pack_vector): Likewise.
7552 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
7553 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
7554 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
7555 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
7557 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
7558 (ARGMATCH_CONSTRAINT): New macro.
7559 (ARGMATCH_ASSERT): Use it.
7561 * src/system.h (verify): New macro.
7562 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
7564 * src/tables.c (tables_generate): Likewise.
7566 * src/struniq.c (struniq_assert): Now returns void, and aborts
7567 if the assertion is false.
7568 (struniq_assert_p): Remove.
7569 * src/struniq.h: Likewise.
7571 2002-11-18 Paul Eggert <eggert@twinsun.com>
7573 * data/glr.c (yygetLRActions): Replace `yyindex' with
7574 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
7575 This fixes the regression with Sun ONE Studio 7 cc that I reported in
7576 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
7578 2002-11-18 Akim Demaille <akim@epita.fr>
7580 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
7582 From Tim Van Holder.
7584 2002-11-17 Paul Eggert <eggert@twinsun.com>
7586 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
7587 to "SyntaxError" for consistency with my 2002-11-15 change.
7589 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
7590 not define to {}, since this breaks the common use of `YYDPRINTF
7591 ((...));' if a single statement is desired (e.g. before `else').
7592 Work around GCC warnings by surrounding corresponding calls with
7594 (yyhasResolvedValue): Remove unused function.
7595 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
7597 (yyreportSyntaxError): Renamed from yyreportParseError.
7598 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
7600 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
7601 extern when possible. Remove unused initializations.
7603 2002-11-16 Akim Demaille <akim@epita.fr>
7605 Augment the similarity between GLR and LALR traces.
7607 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
7608 (YY_REDUCE_PRINT): New.
7609 (yyparse): Use them.
7610 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
7612 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
7613 state reached after the reduction/recovery, since...
7614 (yyparse, yyprocessOneStack): Report the state we are entering in.
7616 2002-11-16 Akim Demaille <akim@epita.fr>
7618 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
7619 Add support for --trace=skeleton.
7620 * src/scan-skel.l: %option debug.
7621 Scan strings of non-@ or \n instead of character by character.
7622 (scan_skel): Handle trace_skeleton.
7624 (@output_parser_name@, @output_header_name@): ``Restore'' their
7625 support (used to be M4 macros).
7626 * data/yacc.c: Quote larger chunks, a la glr.c.
7627 * data/lalr1.cc: Likewise.
7628 The header guards are no longer available, so use some other
7629 string than `YYLSP_NEEDED'.
7631 2002-11-16 Akim Demaille <akim@epita.fr>
7633 Make the ``Printers and Destructors'' test more verbose, taking
7634 `yacc.c''s behavior as (possibly wrong) reference.
7636 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
7637 instead of fprint on stdout.
7638 Set and report the last_line of the symbols.
7639 Consistently display values and locations.
7641 2002-11-16 Paul Eggert <eggert@twinsun.com>
7643 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
7645 2002-11-15 Paul Eggert <eggert@twinsun.com>
7647 * tests/actions.at (Actions after errors): New test case.
7649 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
7650 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
7651 tests/action.at, tests/calc.at, tests/conflicts.at,
7652 tests/cxx-type.at, tests/regression.at:
7653 "parse error" -> "syntax error" for POSIX compatibility.
7654 "parsing stack overflow..." -> "parser stack overflow" so
7655 that code matches Bison documentation.
7657 2002-11-15 Akim Demaille <akim@epita.fr>
7659 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
7660 take two BRACED_CODE, not two string_content.
7661 Free the scanner's obstack when we are done.
7662 (code_content): New.
7663 * tests/calc.at: Adjust.
7664 * doc/bison.texinfo: Adjust.
7665 Also, make sure to include the `,' for these declarations.
7667 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
7669 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
7670 definition; avoids potential autoreconf problems.
7672 2002-11-15 Akim Demaille <akim@epita.fr>
7674 Always check the value returned by yyparse.
7676 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
7677 returned by yyparse.
7678 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
7680 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
7681 returned by yyparse.
7683 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
7685 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
7688 2002-11-14 Paul Eggert <eggert@twinsun.com>
7690 * src/output.c (output_skeleton): Call xfopen instead of
7691 duplicating xfopen's body.
7693 Fix bugs reported by Nelson H. F. Beebe in
7694 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
7696 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
7697 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
7698 Group compiler. Instead, use "$CC -E bar.c". Include the .h
7699 file twice in the grammar, as an extra check.
7701 * tests/input.at (Torturing the Scanner): Surround the
7702 backslash-newline tests with "#if 0", to make it less likely that
7703 we'll run into compiler bugs. Bring back solitary \ inside
7704 comment, but add a closing comment to work around HP C bug. Don't
7705 test backslash-newline in C character constant.
7707 2002-11-14 Akim Demaille <akim@epita.fr>
7709 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
7710 status of the compiler.
7711 Calling `exit 1' is no longer needed.
7712 Reported by Nelson H. F. Beebe.
7714 2002-11-14 Akim Demaille <akim@epita.fr>
7716 * tests/atlocal.in (CPPFLAGS): We have config.h.
7717 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
7719 * tests/actions.at, tests/calc.at, tests/conflicts.at,
7720 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
7721 * tests/regression.at, tests/torture.at: Use them for all the
7722 grammars that are to be compiled.
7723 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
7724 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
7725 * doc/bison.texinfo (GLR Parsers): Document `inline'.
7727 2002-11-14 Akim Demaille <akim@epita.fr>
7729 * doc/bison.texinfo: Various formatting changes (alignments in
7730 samples, additional @group/@end group, GCS in samples.
7731 Use @deffn instead of simple @table to define the directives,
7732 macros, variables etc.
7734 2002-11-13 Paul Eggert <eggert@twinsun.com>
7736 Fix some bugs reported by Albert Chin-A-Young in
7737 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
7739 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
7740 -o c"; the HP C compiler chatters during compilation.
7741 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
7742 * tests/headers.at (export YYLTYPE): Likewise.
7744 * tests/input.at (Torturing the Scanner): Remove lines containing
7745 solitary backslashes, as they tickle a bug in the HP C compiler.
7747 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
7748 comments, since they're not portable. Use GNU coding style.
7750 2002-11-13 Akim Demaille <akim@epita.fr>
7752 * data/yacc.c: Leave bigger chunks of quoted text.
7753 (YYDSYMPRINTF): New.
7754 Use it to report symbol activities.
7755 * data/glr.c (YYDSYMPRINTF): New.
7758 2002-11-12 Paul Eggert <eggert@twinsun.com>
7762 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
7763 (yyglrReduce): Return yyok, not 0.
7764 This should avoid the enumerated-type warnings reported
7765 by Nelson H. F. Beebe in
7766 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
7768 * lib/bbitset.h (BITSET_INLINE): Remove.
7769 * lib/bitset.h [! BITSET_INLINE]: Remove.
7770 (bitset_set, bitset_reset, bitset_test): Rename local vars
7771 to avoid shadowing warnings by GCC.
7773 * data/glr.c (inline): Remove #define. It's the user's
7774 responsibility to #define it away, just like 'const'.
7775 This fixes one of the bugs reported by Nelson H. F. Beebe in
7776 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
7778 * Makefile.maint (po-check): Scan .l and .y files instead of the
7779 .c and the .h files that they generate. This fixes the bug
7780 reported by Tim Van Holder in:
7781 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
7782 Look for N_ as well as for _. Try to avoid matching #define for
7784 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
7785 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
7786 * src/scan-gram.l: Revamp regular expressions so that " and '
7787 do not confuse xgettext.
7789 * src/struniq.h (struniq_new): Do not declare the return type
7790 to be 'const'; this violates the C standard.
7791 * src/struniq.c (struniq_new): Likewise.
7793 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
7795 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
7796 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
7799 2002-11-12 Akim Demaille <akim@epita.fr>
7801 * Makefile.maint: Sync with Autoconf:
7802 (local_updates): New.

7818 2002-11-12 Akim Demaille <akim@epita.fr>
7820 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
7821 Use it to test the GLR parser.
7823 2002-11-12 Akim Demaille <akim@epita.fr>
7825 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
7827 * data/glr.c (yystos): New.
7828 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
7830 (yyval): Don't define it, it is handled via M4.
7831 (yyrecoverParseError): Free verbosely the discarded symbols.
7832 * data/yacc.c (yysymprint): Remove, rather...
7833 (b4_yysymprint_generate): invoke.
7834 * data/c.m4 (b4_yysymprint_generate): New.
7835 Accept pointers as arguments, as opposed to the version from
7837 (b4_yydestruct_generate): Likewise.
7838 * tests/cations.at (Printers and Destructors): Use Bison directives
7839 instead of CPP macros.
7840 Don't rely on internal details.
7842 2002-11-12 Akim Demaille <akim@epita.fr>
7844 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
7845 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
7846 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
7847 it against YYEMPTY and so forth), work on yytoken (i.e., set
7848 it to YYEMPTY etc.).
7849 (yydestruct): Replace with a b4_yydestruct_generate invocation.
7850 (b4_symbol_actions): Remove.
7851 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
7852 for 0, end-of-input.
7854 2002-11-12 Akim Demaille <akim@epita.fr>
7856 * doc/bison.texinfo (Destructor Decl): New.
7858 2002-11-12 Akim Demaille <akim@epita.fr>
7860 * src/tables.c (tables_generate): Use free for pointers that

7939 Revamp to fix many (but not all) of the C- and M4-related quoting
7940 problems. Among other things, this fixes the Bison bug reported
7941 by Jan Hubicka when processing the Bash grammar; see:
7942 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
7944 Use new @ escapes consistently. Represent brackets with @{ and @}
7945 rather than @<:@ and @:>@, since this works a bit better with dumb
7946 editors like vi. Represent @ with @@, since @ is now consistently
7947 an escape. Use @oline@ and @ofile@ rather than __oline__ and
7948 __ofile__, to avoid unexpected expansions. Similarly, use @output
7949 rather than #output.
7951 * data/c.m4 (b4_copyright): Omit file name from comment, since
7952 the file name could contain "*/".
7953 (b4_synclines_flag): Don't quote the 2nd argument; it should already
7954 be quoted. All uses changed.
7956 * data/glr.c: Use new @ escapes consistently.
7957 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
7958 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
7959 Remove, since they couldn't handle arbitrary characters in file
7961 * data/lalr1.cc: Likewise.
7962 * data/yacc.c: Likewise.
7964 * src/files.c (output_infix): Remove; all uses removed.
7965 * src/files.h: Likewise.
7967 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
7968 mishandled funny characters in file names, and anyway it isn't
7970 * data/yacc.c: Likewise.
7971 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
7973 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
7974 * data/yacc.c: Likewise.
7976 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
7978 (muscle_init): Quote filename as a C string.
7979 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
7980 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
7981 * src/output.c (escaped_file_name_output): New function.
7982 (prepare_symbols): Quote tokens for M4.
7983 (prepare): Don't insert output_infix, output_prefix,
7984 output_parser_name, output_header_name; this is now down by scan-skel.
7985 Insert skeleton as a C string.
7987 * src/output.c (user_actions_output, symbol_destructors_output,
7988 symbol_printers_output): Quote filenames for C and M4.
7989 * src/reader.c (prologue_augment, epilogue_set): Likewise.
7991 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
7992 escapes other than \\ and \'; this simplifies the code.
7993 (<SC_STRING>): Likewise, for \\ and \".
7994 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
7995 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
7996 Use new escapes @{ and @} for [ and ].
7998 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
7999 them with auto vars.
8000 Switch to new escape scheme, where @ is the escape character uniformly.
8001 Abort if a stray escape character is found. Avoid unbounded input
8002 buffer when parsing non-escaped text.
8004 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
8005 __oline__, #output, $@, and @{ do not have unintended meanings.
8007 2002-11-09 Paul Eggert <eggert@twinsun.com>
8009 Fix the test failure due to GCC warnings described in
8010 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
8011 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
8012 evaluate to 0 if it's impossible for NINF to be in the respective
8014 (yygetLRActions, yyrecoverParseError): Use them.
8016 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
8017 counted in the token inserted at end of file. Now takes
8018 location_t *, not location_t, so that the location can be
8019 adjusted. All uses changed.
8021 * tests/regression.at (Invalid inputs): Adjust wording in
8022 diagnostic to match the new behavior.
8024 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
8025 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
8026 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
8027 abort ();'. This reduces the runtime of the "Many lookaheads"
8028 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
8031 2002-11-07 Paul Eggert <eggert@twinsun.com>
8033 * src/parse-gram.y (CHARACTER): Remove unused token.
8036 * src/scan-gram.l: Remove stack option. We no longer use the
8037 stack, since the stack was never deeper than 1; instead, use the
8038 new auto var c_context to record the stacked value.
8040 Remove nounput option. At an unexpected end of file, we now unput
8041 the minimal input necessary to end cleanly; this simplifies the
8044 Avoid unbounded token sizes where this is easy.
8046 (unexpected_end_of_file): New function.
8047 Use it to systematize the error message on unexpected EOF.
8048 (last-string): Now auto, not static.
8049 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
8050 (scanner_last_string_free): Remove; not used.
8051 (percent_percent_count): Move decl to just before use.
8052 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
8053 not the (never otherwised-used) CHARACTER.
8055 2002-11-07 Akim Demaille <akim@epita.fr>

8075 * src/output.c (symbol_printers_output)
8076 (symbol_destructors_output): Quote the file name.

8105 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
8107 * src/tables.c (matching_state): Don't allow states to match if
8108 either has GLR conflict entries.
8110 2002-11-05 Paul Eggert <eggert@twinsun.com>
8112 * src/scan-gram.l: Use more accurate diagnostics, e.g.
8113 "integer out of range" rather than "invalid value".
8114 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
8117 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
8118 Also, remove one static variable in the scanner.
8120 * src/scan-gram.l (braces_level): Now auto, not static.
8121 Initialize to zero if the compiler is being picky.
8122 (INITIAL): Clear braces_level instead of incrementing it.
8123 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
8124 as POSIX 1003.1-2001 requires.
8125 * src/system.h (IF_LINT): New macro, taken from coreutils.
8126 * configure.ac: Define "lint" if --enable-gcc-warnings.
8128 2002-11-05 Akim Demaille <akim@epita.fr>
8130 * src/scan-gram.l: When it starts with `%', complain about the

8159 * src/reader.c (get_merge_function, grammar_current_rule_check):
8160 Use consistent diagnostics for reporting type name clashes.

8179 (yyreportAmbiguity): When using a pure parser, also need
8180 the location, and the parse-params.
8182 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
8183 When using a pure parser, also need the parse-params.

8206 2002-11-03 Paul Eggert <eggert@twinsun.com>
8208 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
8209 to count columns correctly, and to check for invalid inputs.

8266 2002-11-02 Paul Eggert <eggert@twinsun.com>
8268 * src/reader.c: Don't include quote.h; not needed.

8272 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
8273 bug in trigraph handling.
8275 * src/output.c (prepare_symbols): When printing token names,
8276 escape "[" as "@<:@" and likewise for "]".
8278 * src/system.h (errno): Remove declaration, as we are now
8279 assuming C89 or better, and C89 guarantees errno.
8281 2002-10-30 Paul Eggert <eggert@twinsun.com>
8283 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):

8287 * src/files.c (xfclose): Likewise. Report I/O error if ferror
8289 * src/output.c (output_skeleton): Use xfclose rather than fclose
8290 and ferror. xfclose now checks ferror.
8292 * data/glr.c (YYLEFTMOST_STATE): Remove.
8293 (yyreportTree): Use a stack-based leftmost state. This avoids
8294 our continuing battles with bogus warnings about initializers.

8311 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
8312 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
8313 we use malloc. Don't assume 'A' through 'Z' are contiguous.
8314 Don't assume strdup exists; POSIX says its an XSI extension.
8315 Check for buffer overflow on input.
8317 2002-10-24 Akim Demaille <akim@epita.fr>
8319 * src/output.c (output_skeleton): Don't disable M4sugar comments

8335 * src/main.c (main): With --trace=time, report times even if a
8336 non-fatal error occurs. Formerly, the times were reported in some
8337 such cases but not in others.
8338 * src/reader.c (reader): Just return if a complaint has been issued,
8339 instead of exiting, so that 'main' can report times.
8341 2002-10-22 Akim Demaille <akim@epita.fr>
8343 * src/system.h: Include sys/types.
8344 Reported by Bert Deknuydt.

8349 Suggested by Art Haas.
8351 2002-10-22 Paul Eggert <eggert@twinsun.com>
8353 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
8354 decl; not needed any more.
8355 * src/main.c (main): Use return to exit, undoing yesterday's change.
8356 The last OS that we could find where this wouldn't work is
8357 SunOS 3.5, and that's too old to worry about now.
8359 * data/glr.c (struct yyltype): Define members even when not
8360 doing locations. This is more consistent with yacc.c, and it
8361 works around the following bug reports:
8362 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
8363 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
8365 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
8366 @acronym consistently. Standardize on "Yacc" instead of "YACC",
8367 "Algol" instead of "ALGOL". Give a bit more history about BNF.
8369 2002-10-22 Akim Demaille <akim@epita.fr>
8373 2002-10-21 Paul Eggert <eggert@twinsun.com>
8375 Be consistent about 'bool'; the old code used an enum in one
8376 module and an int in another, and this violates the C standard.
8377 * m4/stdbool.m4: New file, from coreutils 4.5.3.
8378 * configure.ac (AC_HEADER_STDBOOL): Add.
8379 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.

8381 * src/symtab.c (hash_compare_symbol_t): Likewise.
8382 * src/system.h (bool, false, true): Use a definition consistent
8383 with ../lib/hash.c. All uses changed.
8385 * src/complain.c (warning_issued): Renamed from warn_message_count,
8386 so that we needn't worry about integer overflow (!).
8387 Now of type bool. All uses changed.
8388 (complaint_issued): Renamed from complain_message_count; likewise.
8390 * src/main.c (main): Use exit to exit with failure.
8392 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
8393 rather than 1 and 0.
8394 * src/main.c (main): Likewise.
8395 * src/getargs.c (getargs): Likewise.
8396 * src/reader.c (reader): Likewise.
8398 * src/getarg.c (getargs): Remove duplicate code for
8399 "Try `bison --help'".
8401 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
8402 What was that "2" for?
8404 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
8405 * src/getargs.c (usage): Likewise.
8407 * src/getargs.c (getargs): When there are too few operands, report
8408 the last one. When there are too many, report the first extra
8409 one. This is how diffutils does it.
8411 2002-10-20 Paul Eggert <eggert@twinsun.com>
8413 Remove K&R vestiges.
8414 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
8415 * src/complain.c (VA_START): Remove. Assume prototypes.
8416 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
8417 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
8418 fatal): Assume prototypes.
8419 * src/complain.h: Assume prototypes.
8420 * src/system.h (PARAMS): Remove.
8421 Include <limits.h> unconditionally, since it's guaranteeed even
8422 for a freestanding C89 compiler.
8423 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
8424 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
8426 2002-10-20 Akim Demaille <akim@epita.fr>
8428 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
8429 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
8430 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
8431 (yyresolveStates, yyresolveAction, yyresolveStack)
8432 (yyprocessOneStack): Use them.
8433 (yy_reduce_print): New.
8434 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.

8438 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
8439 arguments and output `void'.
8440 (b4_c_function): Rename as...
8441 (b4_c_function_def): this.
8442 (b4_c_function_decl, b4_c_ansi_function_def)
8443 (b4_c_ansi_function_decl): New.
8444 Change the interpretation of the arguments: before `int, foo', now
8446 * data/yacc.c (yyparse): Prototype and define thanks to these.
8447 Adjust b4_c_function_def uses.
8448 * data/glr.c (yyparse): Likewise, but ANSI only.
8450 2002-10-20 Akim Demaille <akim@epita.fr>
8452 * src/output.c (prepare): Move the definition of `tokens_number',
8453 `nterms_number', `undef_token_number', `user_token_number_max'
8455 (prepare_tokens): Here.
8456 (prepare_tokens): Rename as...
8457 (prepare_symbols): this.
8458 (prepare): Move the definition of `rules_number' to...
8459 (prepare_rules): here.
8460 (prepare): Move the definition of `last', `final_state_number',
8461 `states_number' to...

8476 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
8477 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
8479 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',

8482 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
8485 2002-10-19 Paul Eggert <eggert@twinsun.com>
8487 Do not create a temporary file, as that involves security and
8488 cleanup headaches. Instead, use a pair of pipes.
8489 Derived from a suggestion by Florian Krohm.
8490 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
8491 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
8492 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
8493 (BISON_PREREQ_SUBPIPE): Add.

8498 * src/output.c: Include "subpipe.h".
8499 (m4_invoke): Remove decl.
8500 (scan_skel): New decl.
8501 (output_skeleton): Use pipe rather than temporary file for m4 input.
8502 Check that m4sugar.m4 is readable, to avoid deadlock.
8503 Check for pipe I/O error.
8504 * src/scan-skel.l (readpipe): Remove decl.
8505 (scan_skel): New function, to be used in place of m4_invoke.
8506 Read from stream rather than file.
8508 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
8509 float, as this generates a warning on Solaris 8 + GCC 3.2 with
8510 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
8511 this generates a more-accurate value anyway.
8513 * lib/timevar.c (timervar_accumulate): Rename locals to
8514 avoid confusion with similarly-named more-global.
8515 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
8517 * src/output.c (prepare): Use xstrdup to convert char const *
8518 to char *, to avoid GCC warning.
8520 2002-10-19 Akim Demaille <akim@epita.fr>
8522 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
8523 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
8524 Use them to have `calc.y' ready for %pure-parser.
8525 * data/yacc.c (YYLEX): Pass a yylex return type to
8528 2002-10-19 Akim Demaille <akim@epita.fr>
8530 Prototype support of %lex-param and %parse-param.
8532 * src/parse-gram.y: Add the definition of the %lex-param and
8533 %parse-param tokens, plus their rules.
8534 Drop the `_' version of %glr-parser.
8536 * src/scan-gram.l (INITIAL): Scan them.
8537 * src/muscle_tab.c: Comment changes.
8538 (muscle_insert, muscle_find): Rename `pair' as `probe'.
8539 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
8540 (muscle_entry_s): The `value' member is no longer const.
8541 Adjust all dependencies.
8542 * src/muscle_tab.c (muscle_init): Adjust: use
8543 MUSCLE_INSERT_STRING.
8544 Initialize the obstack earlier.
8545 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
8546 (muscle_pair_list_grow): New.
8547 * data/c.m4 (b4_c_function_call, b4_c_args): New.

8552 2002-10-19 Akim Demaille <akim@epita.fr>
8554 * src/getargs.c (usage): Take status as argument and exit
8556 Report the traditional `Try ... --help' message when status != 0.
8557 (usage, version): Don't take a FILE * as arg, it is pointless.
8558 (getargs): When there is an incorrect number of arguments, make it
8559 an error, and report it GNUlically thanks to `usage ()'.
8561 2002-10-18 Paul Eggert <eggert@twinsun.com>
8563 * data/glr.c (yyreportParseError): Don't assume that sprintf
8564 yields the length of the printed string, as this is not true
8565 on SunOS 4.1.4. Reported by Peter Klein.
8567 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
8568 * tests/conflicts.at (%nonassoc and eof): Likewise.
8569 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
8571 2002-10-17 Akim Demaille <akim@epita.fr>
8573 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
8574 * src/getargs.c (trace_types, trace_args): Adjust.
8575 * src/reader.c (grammar_current_rule_prec_set)
8576 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
8577 Standardize error messages.
8579 (reader): Use trace_flag to enable scanner/parser debugging,
8580 instead of an adhoc scheme.
8581 * src/scan-gram.l: Remove trailing debugging code.
8583 2002-10-16 Paul Eggert <eggert@twinsun.com>
8585 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
8588 * NEWS: Officially drop support for building Bison with K&R C,
8589 since it didn't work anyway and it's not worth worrying about.
8590 * Makefile.maint (wget_files): Remove ansi2knr.c.
8591 (ansi2knr.c-url_prefix): Remove.
8592 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
8593 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
8594 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
8596 2002-10-15 Paul Eggert <eggert@twinsun.com>
8598 Stop using the "enum_" trick for K&R-style function definitions;
8599 it confused me, and I was the author! Instead, assume that people
8600 who want to use K&R C compilers (when using these modules in GCC,
8601 perhaps?) will run ansi2knr.
8603 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
8604 All uses of "enum_" changed to "enum ".
8605 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.

8616 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
8617 Use function prototypes; this removes the need for declaring
8618 static functions simply to provide their prototypes.
8619 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

8693 tests/cxx-type.at, tests/headers.at, tests/input.at,
8694 tests/regression.at, tests/synclines.at, tests/torture.at:
8695 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
8696 so that the tests still work even if POSIXLY_CORRECT is set.
8697 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
8699 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
8700 for portability to K&R hosts. Fix typo: signed char is guaranteed
8701 only to 127, not to 128.
8702 * data/glr.c (yysigned_char): New type.
8703 * data/yacc.c (yysigned_char): Likewise.
8704 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
8706 2002-10-13 Paul Eggert <eggert@twinsun.com>
8708 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
8709 true due to limited range of data type" warning from GCC.
8711 * data/c.m4 (b4_token_defines): Protect against double-inclusion
8712 by wrapping enum yytokentype's definition inside #ifndef
8713 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
8715 2002-10-13 Akim Demaille <akim@epita.fr>
8717 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
8718 Un yy- yyrhs to avoid the name clash with the global YYRHS.
8720 2002-10-13 Akim Demaille <akim@epita.fr>
8722 * Makefile.maint: Update from Autoconf 2.54.
8723 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
8725 2002-10-13 Akim Demaille <akim@epita.fr>
8727 * src/print.c (print_state): Separate the list of solved conflicts
8728 from the other items.
8729 * tests/conflicts.at (Resolved SR Conflicts): Adjust.

8733 Let nondeterministic skeletons be usable with deterministic
8736 With the patch, GAWK compiled by GCC without -O2 passes its test
8737 suite using a GLR parser driven by LALR tables. It fails with -O2
8738 because `struct stat' gives two different answers on my machine:
8739 88 (definition of an auto var) and later 96 (memset on this var).
8740 Hence the stack is badly corrumpted. The headers inclusion is to
8741 blame: if I move the awk.h inclusion before GLR's system header
8742 inclusion, the two struct stat have the same size.
8744 * src/tables.c (pack_table): Always create conflict_table.
8745 (token_actions): Always create conflict_list.
8746 * data/glr.c (YYFLAG): Remove, unused.
8748 2002-10-13 Akim Demaille <akim@epita.fr>
8750 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
8752 (VALGRIND, GXX): New.
8753 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
8754 * tests/bison.in: Run $PREBISON a pre-command.
8755 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
8756 (maintainer-check-g++): New.
8757 * Makefile.am (maintainer-check): New.
8759 2002-10-13 Akim Demaille <akim@epita.fr>
8761 * data/glr.c: Formatting changes.
8762 Tweak some trace messages to match yacc.c's.
8764 2002-10-13 Akim Demaille <akim@epita.fr>
8766 GLR parsers sometimes raise parse errors instead of performing the
8768 Reported by Charles-Henry de Boysson.
8770 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
8771 check the length of the traces when %glr.
8772 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
8774 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
8776 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
8777 (yyltype): Remove the yy prefix from the member names.
8778 (yytable): Complete its comment.
8779 (yygetLRActions): Map error action number from YYTABLE from
8781 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
8782 (which was a bug: it should have been YYTABEL_NINF, and yet it was
8783 not satisfying as we could compare an YYACTION computed from
8784 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
8785 only value for error actions.
8786 (yyreportParseError): In verbose parse error messages, don't issue
8787 `error' in the list of expected tokens.
8788 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
8789 next action to perform to match glr.c's decoding.
8790 (yytable): Complete its comment.
8792 2002-10-13 Paul Eggert <eggert@twinsun.com>
8794 Fix problem reported by Henrik Grubbstroem in
8795 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
8796 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
8797 because the Bison parser reads the second action before reducing
8799 * src/scan-gram.l (rule_length): New static var.
8800 Use it to keep track of the rule length in the scanner, since
8801 we can't expect the parser to be in lock-step sync with the scanner.
8802 (handle_action_dollar, handle_action_at): Use this var.
8803 * tests/actions.at (Exotic Dollars): Test for the problem.
8805 2002-10-12 Paul Eggert <eggert@twinsun.com>
8807 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
8808 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
8809 Include <sys/time.h> when checking for clock_t and struct tms.
8810 Use same include order as source.
8811 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
8812 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
8814 * lib/timevar.c: Update copyright date and clarify comments.
8815 (get_time) [IN_GCC]: Keep the GCC version for reference.
8817 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
8818 GCC version as of today, then merge Bison's changes.
8819 Change "GCC" to "Bison" in copyright notice. timevar.def's
8820 author is Akim, so change that too.
8822 * src/reader.c (grammar_current_rule_check):
8823 Don't worry about the default action if $$ is untyped.
8824 Prevents bogus warnings reported by Jim Gifford in
8825 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
8827 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
8828 * data/glr.c, data/lalr1.cc, data/yacc.c:
8829 Output token definitions before the first part of user declarations.
8830 Fixes compatibility problem reported by Jim Gifford for kbd in
8831 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
8833 2002-10-11 Paul Eggert <eggert@twinsun.com>
8835 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
8836 (yyparse): here. This undoes some of the 2002-07-25 change.
8837 Compatibility problem reported by Ralf S. Engelschall with
8838 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
8840 2002-10-11 Akim Demaille <akim@epita.fr>

8851 2002-10-10 Paul Eggert <eggert@twinsun.com>
8853 Portability fixes for bitsets; this also avoids several GCC
8856 * lib/abitset.c: Include <stddef.h>, for offsetof.
8857 * lib/lbitset.c: Likewise.
8859 * lib/abitset.c (abitset_bytes): Return a size that is aligned
8860 properly for vectors of objects. Do not assume that adding a
8861 header size to a multiple of a word size yields a value that is
8862 properly aligned for the whole union.
8863 * lib/bitsetv.c (bitsetv_alloc): Likewise.
8865 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
8866 unique names for structures.
8867 * lib/ebitset.c (ebitset_bytes): Likewise.
8868 * lib/lbitset.c (lbitset_bytes): Likewise.
8870 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,

8875 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
8876 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
8877 to improve the type-checking that GCC can do.
8878 * lib/bitset.c (bitset_op4_cmp): Likewise.
8879 * lib/bitset_stats.c (bitset_stats_count,
8880 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,

8887 bitset_stats_andn_or_cmp, bitset_stats_or_and,
8888 bitset_stats_or_and_cmp): Likewise.

8895 * lib/ebitset.h: Likewise.
8896 * lib/lbitset.h: Likewise.
8898 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
8899 All instances of parameters of type enum bitset_opts are now of
8900 type enum_bitset_opts, to conform to the C Standard, and similarly
8901 for enum_bitset_type.
8902 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
8903 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
8905 Do not use "struct bitset_struct" to mean different things in
8906 different modules. Not only is this confusing, it violates
8907 the C Standard, which requires that structure types in different
8908 modules must be compatible if one is to be passed to the other.
8909 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
8910 All instances of "struct bitset_struct *" replaced with "bitset".
8911 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
8912 (union bitset_union, struct abitset_struct, struct ebitset_struct,
8913 struct lbitset_struct, struct bitset_stats_struct): New types.
8914 All uses of struct bitset_struct changed to union bitset_union,
8916 * lib/abitset.c (struct abitset_struct, abitset,
8917 struct bitset_struct): Remove.
8918 * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
8919 struct bitset_struct): Remove.
8920 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
8921 bitset_struct): Remove.
8922 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
8925 Do not call a function of type T using a call that assumes the
8926 function is of a different type U. Standard C requires that a
8927 function must be called with a type that is compatible with its
8929 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
8931 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
8933 * lib/ebitset.c (PFV): Remove.
8934 * lib/lbitset.c (PFV): Likewise.
8935 * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,

8941 lbitset_xor): New functions.
8942 (lbitset_vtable): Use them.
8944 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
8947 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
8949 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
8950 Use offsetof, for simplicity.
8952 2002-10-06 Paul Eggert <eggert@twinsun.com>
8954 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
8955 the same width as int. This reapplies a hunk of the 2002-08-12 patch
8956 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
8957 which was inadvertently undone by the 2002-09-30 patch.
8958 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
8959 the same width as int.
8961 2002-10-04 Paul Eggert <eggert@twinsun.com>
8965 * configure.ac (AC_INIT), NEWS: Increment version number.
8967 * doc/bison.texinfo: Minor spelling, grammar, and white space
8969 (Symbols): Mention that any negative value returned from yylex
8970 signifies end-of-input. Warn about negative chars. Mention
8971 the portable Standard C character set.
8973 The GNU coding standard says CFLAGS and YFLAGS are reserved
8974 for the installer to set.
8975 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
8976 * src/Makefile.am (AM_CFLAGS): Likewise.
8977 (AM_YFLAGS): Renamed from YFLAGS.
8979 Fix some MAX and MIN problems.
8980 * src/gram.h (ITEM_NUMBER_MIN): MIN_MAX -> INT_MIN.
8981 * src/lalr.h (GOTO_NUMBER_MAX): INT_MAX -> SHRT_MAX.
8982 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
8983 * src/reader.c (reader): Use it.
8985 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
8986 POSIX 1003.1-2001 has removed fgrep.
8988 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>
8990 * lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
8991 interpreted as signed.
8992 * lib/ebitset.c (ebitset_list): Fix bug.
8994 2002-10-01 Paul Eggert <eggert@twinsun.com>

9057 * lib/bbitset.h (BITSET_BINDEX_MAX, BITSET_WINDEX_MAX,
9058 BITSET_SIZE_MAX): New macros.
9059 (BITSET_INDEX_MAX): Remove. It wasn't right, since it assumed that
9060 sizeof (bitset_word) == sizeof (bitset_windex). All uses changed
9061 to BITSET_WINDEX_MAX.
9063 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
9064 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,

9219 as int, and similarly for yyposn and YYINDEX.
9221 * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.

9320 this is a GCC extension and is not portable to other compilers.

9502 different: save its reduction (accept) instead of having a state

9559 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
9560 for the time being: %locations ought to provide it to yyerror.

9564 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

11210 * tests/regression.at (Web2c Actions): Adjust.
11212 2002-04-22 Akim Demaille <akim@epita.fr>
11214 * src/reader.c (token_translations_init): 256 is now the default
11215 value for the error token, i.e., it will be assigned another
11216 number if the user assigned 256 to one of her tokens.
11217 (reader): Don't force 256 to error.
11218 * doc/bison.texinfo (Symbols): Adjust.
11219 * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR)
11220 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
11221 etc. instead of 10, 20, 30 (which was used to `jump' over error
11222 (256) and undefined (2)).
11224 2002-04-22 Akim Demaille <akim@epita.fr>

11261 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
11262 full stderr, and strip it according to the bison options, instead

11264 This makes it easier to check for several error messages.
11265 Adjust all the invocations.
11266 Add an invocation exercising the error token.
11267 Add an invocation demonstrating a stupid error message.
11268 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.

11286 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
11287 `user_token_number_max'.

11533 * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
11534 lacking `+ 1' to nrules, Bison reported as useless a token if it
11535 was used solely to set the precedence of the last rule...
11537 2002-04-07 Akim Demaille <akim@epita.fr>
11539 * data/bison.c++, data/bison.simple: Don't output the current file
11540 name in #line, to avoid useless diffs between two identical
11541 outputs under different names.

11545 * src/closure.c, src/print.c, src/reader.c, src/reduce.c:

11566 * doc/bison.texinfo: Update copyright date.
11567 (Rpcalc Lexer, Symbols, Token Decl): Don't assume ASCII.

11706 * src/reduce.c: Remove the `bitset_zero's following the

11793 notice in each output file.
11795 2002-02-28 Akim Demaille <akim@epita.fr>
11797 * data/bison.c++: Copy the prologue of bison.simple to fetch
11798 useful M4 definitions, such as b4_header_guard.
11800 2002-02-25 Akim Demaille <akim@epita.fr>
11802 * src/getargs.c (version): Give the name of the authors, and use a
11803 translator friendly scheme for the bgr
11806 2002-02-25 Akim Demaille <akim@epita.fr>
11808 * src/output.c (header_output): Remove, now handled completely via

11831 2002-02-14 Paul Eggert <eggert@twinsun.com>
11833 Remove the support for C++ namespace cleanliness; it was
11834 causing more problems than it was curing, since it didn't work
11835 properly on some nonstandard C++ compilers. This can wait
11836 for a proper C++ parser.
11838 * NEWS: Document this.
11839 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
11840 of C++, as it's treated like C now.

11854 2002-02-13 Andreas Schwab <schwab@suse.de>
11856 * src/output.c (output_rule_data): Don't output NULL, it might
11857 not be defined yet.
11859 2002-02-11 Robert Anisko <robert@lrde.epita.fr>
11861 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.

11876 * tests/input.at: New.
11878 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
11880 * data/bison.c++: Replace some direct m4 expansions by constants. Be
11881 more consistent when naming methods and variables. Put preprocessor
11882 directives around tables only needed for debugging.
11884 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
11886 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
11888 (yy::b4_name::parse): Use print_.
11890 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
11892 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
11894 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
11896 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
11898 (yy::b4_name::parse): Build verbose error messages, and use error_.
11900 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
11902 * data/bison.c++: Fix m4 quoting in comments.
11904 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
11906 * data/bison.c++: Adjust the parser code. Fix some muscles that were
11907 not expanded by m4.
11909 2002-02-05 Akim Demaille <akim@epita.fr>
11911 * data/bison.c++: Adjust to the M4 back end.
11912 More is certainly needed.
11914 2002-02-05 Akim Demaille <akim@epita.fr>
11916 Give a try to M4 as a back end.
11918 * lib/readpipe.c: New, from wdiff.
11919 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
11921 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
11922 specific values. Now it is m4 that performs the lookup.
11923 * src/parse-skel.y: Remove.
11924 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
11925 * src/output.c (actions_output, guards_output)
11926 (token_definitions_output): No longer keeps track of the output
11927 line number, hence remove the second argument.
11928 (guards_output): Check against the guard member of a rule, not the
11931 (output_skeleton): Don't look for the skeleton location, let m4 do
11933 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
11935 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
11936 (prepare): Given that for the time being changesyntax is not
11937 usable in M4, rename the muscles using `-' to `_'.
11938 Define `defines_flag', `output_parser_name' and `output_header_name'.
11939 * src/output.h (actions_output, guards_output)
11940 (token_definitions_output): Adjust prototypes.
11941 * src/scan-skel.l: Instead of scanning the skeletons, it now
11942 processes the output of m4: `__oline__' and `#output'.
11943 * data/bison.simple: Adjust to be used by M4(sugar).
11944 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
11946 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
11947 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
11948 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
11949 shamelessly stolen from CVS Autoconf.
11951 2002-02-05 Akim Demaille <akim@epita.fr>
11953 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
11954 * configure.in: Check for the declarations of free and malloc.
11955 * src/muscle_tab.c: Adjust.
11957 2002-02-05 Akim Demaille <akim@epita.fr>
11959 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
11960 which have no values.
11962 2002-02-05 Akim Demaille <akim@epita.fr>
11964 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
11967 2002-01-29 Paul Eggert <eggert@twinsun.com>
11969 * src/bison.simple (YYSIZE_T): Do not define merely because
11970 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
11971 On some platforms, <alloca.h> does not declare YYSTD (size_t).
11973 2002-01-27 Akim Demaille <akim@epita.fr>
11975 Fix `%nonassoc and eof'.
11977 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
11978 which were not properly copied! Replace
11979 memcpy (res->errs, src->errs, src->nerrs);
11981 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
11983 * tests/regression.at (%nonassoc and eof): Adjust to newest
11984 Autotest: `.' is not in the PATH.
11986 2002-01-27 Akim Demaille <akim@epita.fr>
11988 * tests/sets.at (AT_EXTRACT_SETS): New.
11989 (Nullable): Use it.
11992 2002-01-26 Akim Demaille <akim@epita.fr>
11994 * tests/actions.at, tests/calc.at, tests/headers.at,
11995 * tests/torture.at: Adjust to the newest Autotest which no longer
11996 forces `.' in the PATH.
11998 2002-01-25 Akim Demaille <akim@epita.fr>
12000 * tests/regression.at (%nonassoc and eof): New.
12001 Suggested by Robert Anisko.
12003 2002-01-24 Akim Demaille <akim@epita.fr>
12005 Bison dumps core when trying to complain about broken input files.
12006 Reported by Cris van Pelt.
12008 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
12009 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
12011 (Invalid inputs): Strengthen: exercise parse_percent_token.
12013 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
12015 * src/Makefile.am: Add bison.c++.
12016 * src/bison.c++: New skeleton.
12018 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
12022 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
12024 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
12026 2002-01-20 Marc Autret <marc@gnu.org>
12028 * src/files.c (compute_output_file_names): Fix
12030 2002-01-20 Marc Autret <marc@gnu.org>
12032 * tests/output.at: New test.
12033 * src/files.c (compute_base_names): Don't map extensions when
12034 the YACC flag is set, use defaults.
12035 Reported by Evgeny Stambulchik.
12037 2002-01-20 Marc Autret <marc@gnu.org>
12039 * src/system.h: Need to define __attribute__ away for non-GCC
12040 compilers as well (i.e., the vendor C compiler).
12041 Suggested by Albert Chin-A-Young.
12043 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
12045 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
12046 canonical definition.
12047 * src/system.h: Use the canonical definition for PARAMS (avoids
12048 a conflict with the macro from lib/hash.h).
12050 2002-01-11 Akim Demaille <akim@epita.fr>
12052 * configure.in: Use AC_FUNC_STRNLEN.
12053 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
12055 2002-01-09 Akim Demaille <akim@epita.fr>
12057 * src/files.c, src/files.h (output_infix): New.
12058 (tab_extension): Remove.
12059 (compute_base_names): Compute the former, drop the latter.
12060 * src/output.c (prepare): Insert the muscles `output-infix', and
12062 * src/parse-skel.y (string, string.1): New.
12063 (section.header): Use it.
12064 (section.yacc): Remove.
12065 (prefix): Remove too.
12066 * src/scan-skel.l: Adjust.
12067 * src/bison.simple, src/bison.hairy: Adjust.
12069 2002-01-09 Akim Demaille <akim@epita.fr>
12071 * configure.in (WERROR_CFLAGS): Compute it.
12072 * src/Makefile.am (CFLAGS): Pass it.
12073 * tests/atlocal.in (CFLAGS): Idem.
12074 * src/files.c: Fix a few warnings.
12075 (get_extension_index): Remove, unused.
12077 2002-01-08 Akim Demaille <akim@epita.fr>
12079 * src/getargs.c (AS_FILE_NAME): New.
12080 (getargs): Use it to convert DOSish file names.
12081 * src/files.c (base_name): Rename as full_base_name to avoid
12082 clashes with `base_name ()'.
12083 (filename_split): New.
12084 (compute_base_names): N-th rewrite, using filename_split.
12086 2002-01-08 Akim Demaille <akim@epita.fr>
12088 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
12089 New, stolen from the Fileutils 4.1.
12090 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
12091 * configure.in: Check for the presence of memrchr, and of its
12094 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
12096 * lib/hash.h (__P): Added definition for this macro.
12097 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
12098 BUILT_SOURCES, to ensure they are generated first.
12099 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
12100 %error-verbose to allow bootstrapping with bison 1.30x.
12102 2002-01-06 Akim Demaille <akim@epita.fr>
12104 * src/reader.c (parse_braces): Don't fetch the next char, the
12105 convention is to fetch on entry.
12106 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
12107 'switch' without a following semicolon.
12108 * tests/regression.at (braces parsing): New.
12110 2002-01-06 Akim Demaille <akim@epita.fr>
12112 Bison is dead wrong in its RR conflict reports.
12114 * tests/torture.at (GNU Cim Grammar): New.
12115 * src/conflicts.c (count_rr_conflicts): Fix.
12117 2002-01-06 Akim Demaille <akim@epita.fr>
12119 Creating package.m4 from configure.ac causes too many problems.
12121 * tests/Makefile.am (package.m4): Create it by hand,
12122 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
12124 2002-01-06 Akim Demaille <akim@epita.fr>
12126 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
12129 2002-01-04 Paul Eggert <eggert@twinsun.com>
12131 * doc/bison.texinfo (Debugging):
12132 Remove YYSTDERR; it's no longer defined or used.
12133 Also, s/cstdio.h/cstdio/.
12135 2002-01-03 Akim Demaille <akim@epita.fr>
12137 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
12139 2002-01-03 Akim Demaille <akim@epita.fr>
12141 * src/parse-skel.y (process_skeleton): Don't bind the parser's
12142 tracing code to --trace, wait for a better --trace option, with
12145 2002-01-03 Akim Demaille <akim@epita.fr>
12147 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
12148 The ISO C++ standard is extremely clear about it: stderr is
12149 considered a macro, not a regular symbol (see table 94 `Header
12150 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
12151 Therefore std:: does not apply to it. It still does with fprintf.
12152 Also, s/cstdio.h/cstdio/.
12154 2002-01-03 Akim Demaille <akim@epita.fr>
12156 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
12157 for non system headers.
12159 2002-01-02 Akim Demaille <akim@epita.fr>
12161 Equip the skeleton chain with location tracking, runtime trace,
12162 pure parser and scanner.
12164 * src/parse-skel.y: Request a pure parser, locations, and prefix
12166 (%union): Having several members with the same type does not help
12167 type mismatches, simplify.
12168 (YYPRINT, yyprint): New.
12169 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
12170 (skel_error): this.
12172 * src/scan-skel.l: Adjust to these changes.
12173 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
12174 (LOCATION_PRINT, skel_control_t): New.
12176 2001-12-30 Akim Demaille <akim@epita.fr>
12178 * src/parse-skel.y: Get rid of the shift/reduce conflict:
12179 replace `gb' with BLANKS.
12180 * src/scan-skel.l: Adjust.
12182 2001-12-30 Akim Demaille <akim@epita.fr>
12184 * src/system.h: We don't need nor want bcopy.
12185 Throw away MS-DOS crap: we don't need getpid.
12186 * configure.in: We don't need strndup. It was even causing
12187 problems: because Flex includes the headers *before* us,
12188 _GNU_SOURCE is not defined by config.h, and therefore strndup was
12190 * lib/xstrndup.c: New.
12191 * src/scan-skel.l: Use it.
12192 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
12193 * src/parse-skel.y: Use %directives instead of #defines.
12195 2001-12-30 Akim Demaille <akim@epita.fr>
12197 * src/skeleton.h: New.
12198 * src/output.c (output_parser, output_master_parser): Remove, dead
12200 * src/output.h (get_lines_number, actions_output, guards_output)
12201 (token_definitions_output): Prototype them.
12202 * src/parse-skel.y: Add the license notice.
12203 Include output.h and skeleton.h.
12204 (process_skeleton): Returns void, and takes a single parameter.
12205 * src/scan-skel.l: Add the license notice.
12206 Include skeleton.h.
12207 Don't use %option yylineno: it seems that then Flex imagines
12208 REJECT has been used, and therefore it won't reallocate its
12209 buffers (which makes no other sense to me than a bug). It results
12210 in warnings for `unused: yy_flex_realloc'.
12212 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
12214 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
12215 (MUSCLE_INSERT_PREFIX): ...to there.
12216 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
12217 (MUSCLE_INSERT_PREFIX): Move from here...
12219 * src/bison.hairy: Add a section directive. Put braces around muscle
12220 names. This parser skeleton is still broken, but Bison should not
12221 choke on a bad muscle 'syntax'.
12222 * src/bison.simple: Add a section directive. Put braces around muscle
12225 * src/files.h (strsuffix, stringappend): Add declarations.
12226 (tab_extension): Add declaration.
12227 (short_base_name): Add declaration.
12229 * src/files.c (strsuffix, stringappend): No longer static. These
12230 functions are used in the skeleton parser.
12231 (tab_extension): New.
12232 (compute_base_names): Use the computations done in this function
12233 to guess if the generated parsers should have '.tab' in their
12235 (short_base_name): No longer static.
12237 * src/output.c (output_skeleton): New.
12238 (output): Disable call to output_master_parser, and give a try to
12239 a new skeleton handling system.
12240 (guards_output, actions_output): No longer static.
12241 (token_definitions_output, get_lines_number): No longer static.
12243 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
12245 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
12248 * src/parse-skel.y: New file.
12249 * src/scan-skel.l: New file.
12251 2001-12-29 Akim Demaille <akim@epita.fr>
12253 %name-prefix is broken.
12255 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
12256 Adjust all dependencies.
12257 * tests/headers.at (export YYLTYPE): Strengthen this test: use
12260 Renaming yylval but not yylloc is not consistent. Now we do.
12262 * src/bison.simple: Prefix yylloc if used.
12263 * doc/bison.texinfo (Decl Summary): Document that.
12265 2001-12-29 Akim Demaille <akim@epita.fr>
12267 * doc/bison.texinfo: Promote `%long-directive' over
12269 Remove all references to fixed-output-files, yacc is enough.
12271 2001-12-29 Akim Demaille <akim@epita.fr>
12273 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
12274 user prologue. These are defaults.
12275 * tests/actions.at (Mid-rule actions): Make sure the user can
12276 define YYDEBUG and YYERROR_VERBOSE.
12278 2001-12-29 Akim Demaille <akim@epita.fr>
12280 * src/output.c (header_output): Don't forget to export YYLTYPE and
12282 * tests/headers.at (export YYLTYPE): New, make sure it does.
12283 * tests/regression.at (%union and --defines, Invalid CPP headers):
12285 * tests/headers.at: here.
12287 2001-12-29 Akim Demaille <akim@epita.fr>
12289 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
12291 2001-12-29 Akim Demaille <akim@epita.fr>
12293 * tests/actions.at (Mid-rule actions): Output on a single line
12294 instead of several.
12296 2001-12-29 Akim Demaille <akim@epita.fr>
12298 * doc/bison.texinfo: Formatting changes.
12300 2001-12-29 Akim Demaille <akim@epita.fr>
12302 Don't store the token defs in a muscle, just be ready to output it
12303 on command. Now possible via `symbols'. Fixes a memory leak.
12305 * src/output.c (token_definitions_output): New.
12306 (output_parser, header_output): Use it.
12307 * src/reader.c (symbols_save): Remove.
12309 2001-12-29 Akim Demaille <akim@epita.fr>
12311 * src/bison.simple: Do not provide a default for YYSTYPE and
12312 YYLTYPE before the user's prologue. Otherwise it's hardly... a
12315 2001-12-29 Akim Demaille <akim@epita.fr>
12317 Mid-rule actions are simply... ignored!
12319 * src/reader.c (readgram): Be sure to attach mid-rule actions to
12320 the empty-rule associated to the dummy symbol, not to the host
12322 * tests/actions.at (Mid-rule actions): New.
12324 2001-12-29 Akim Demaille <akim@epita.fr>
12328 * src/reader.c (reader): Free grammar.
12330 2001-12-29 Akim Demaille <akim@epita.fr>
12334 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
12335 since it allocates it for each state, although only one is needed.
12336 (allocate_storage): Do it here.
12338 2001-12-29 Akim Demaille <akim@epita.fr>
12340 * src/options.h, src/options.c (create_long_option_table): Rename
12342 (long_option_table_new): this, with a clearer prototype.
12343 (percent_table): Remove, unused,
12344 * src/getargs.c (getargs): Adjust.
12346 2001-12-29 Akim Demaille <akim@epita.fr>
12348 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
12349 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
12352 2001-12-29 Akim Demaille <akim@epita.fr>
12354 * src/lalr.c (build_relations): Rename `states' as `states1'.
12355 Sorry, I don't understand exactly what it is, no better name...
12357 2001-12-29 Akim Demaille <akim@epita.fr>
12359 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
12360 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
12361 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
12364 2001-12-29 Akim Demaille <akim@epita.fr>
12366 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
12369 2001-12-29 Akim Demaille <akim@epita.fr>
12371 * src/reader.c, src/reader.h (user_toknums): Remove.
12372 Adjust all users to use symbols[i]->user_token_number.
12374 2001-12-29 Akim Demaille <akim@epita.fr>
12376 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
12377 Adjust all users to use symbols[i]->prec or ->assoc.
12379 2001-12-29 Akim Demaille <akim@epita.fr>
12381 * src/reader.c, src/reader.h (tags): Remove.
12382 Adjust all users to use symbols[i]->tag.
12384 2001-12-29 Akim Demaille <akim@epita.fr>
12386 * src/gram.h, src/gram.c (symbols): New, similar to state_table
12388 * src/reader.c (packsymbols): Fill this table.
12390 * src/conflicts.c (resolve_sr_conflict): Adjust.
12391 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
12393 Use symbols[i]->tag instead of tags[i].
12395 2001-12-29 Akim Demaille <akim@epita.fr>
12397 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
12398 In addition, put a comment in there, to replace...
12399 * tests/regression.at (%union and C comments): Remove.
12401 2001-12-29 Akim Demaille <akim@epita.fr>
12403 * tests/regression.at (Web2c Actions): Blindly move the actual
12404 output as expected output. The contents *seem* right to me, but I
12405 can't pretend reading perfectly parser tables... Nonetheless, all
12406 the other tests pass correctly, the table look OK, even though the
12407 presence of `$axiom' is to be noted: AFAICS it is useless (but
12410 2001-12-29 Akim Demaille <akim@epita.fr>
12412 * src/reader.c (readgram): Don't add the rule 0 if there were no
12413 rules read. In other words, add it _after_ having performed
12414 grammar sanity checks.
12415 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
12417 2001-12-29 Akim Demaille <akim@epita.fr>
12419 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
12420 visible, and some states have now a different number.
12422 2001-12-29 Akim Demaille <akim@epita.fr>
12424 * src/reader.c (readgram): Bind the initial rule's lineno to that
12426 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
12427 (Solved SR Conflicts): Adjust rule 0's line number.
12429 2001-12-29 Akim Demaille <akim@epita.fr>
12431 Fix the `GAWK Grammar' failure.
12433 * src/LR0.c (final_state): Initialize to -1 so that we do compute
12434 the reductions of the first state which was mistakenly confused
12435 with the final state because precisely final_state was initialized
12437 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
12438 now noticed by Bison.
12439 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
12440 have a reduction on $default.
12442 2001-12-29 Akim Demaille <akim@epita.fr>
12444 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
12446 * src/closure.c (print_closure): Likewise.
12447 * src/derives.c (print_derives): Likewise.
12448 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
12451 2001-12-29 Akim Demaille <akim@epita.fr>
12453 * src/lalr.c (lookaheads_print): New.
12454 (lalr): Call it when --trace-flag.
12455 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
12458 2001-12-29 Akim Demaille <akim@epita.fr>
12460 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
12461 when walking through ritem, even via rule->rhs.
12462 * src/reduce.c (dump_grammar, useful_production, reduce_output)
12463 (useful_production, useless_nonterminals): Likewise.
12464 (reduce_grammar_tables): Likewise, plus update nritems.
12465 * src/nullable.c (set_nullable): Likewise.
12466 * src/lalr.c (build_relations): Likewise.
12467 * tests/sets.at (Nullable): Adjust.
12468 Fortunately, now, the $axiom is no longer nullable.
12470 2001-12-29 Akim Demaille <akim@epita.fr>
12472 * src/LR0.c (generate_states): Use nritems, not nitems, nor using

12475 * src/reduce.c (nonterminals_reduce): Likewise.
12476 * src/print_graph.c (print_graph): Likewise.
12477 * src/output.c (output_rule_data): Likewise.
12478 * src/nullable.c (set_nullable): Likewise.
12480 2001-12-29 Akim Demaille <akim@epita.fr>
12482 * src/output.c: Comment changes.
12484 2001-12-27 Paul Eggert <eggert@twinsun.com>
12486 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
12487 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
12488 Sparc, as they were causing more porting problems than the
12489 (minor) performance improvement was worth.
12491 Also, catch up with 1.31's YYSTD.
12493 2001-12-27 Akim Demaille <akim@epita.fr>
12495 * src/output.c (output_gram): Rely on nritems, not the
12496 0-sentinel. See below.
12497 Use -1 as separator, not 0.
12498 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
12499 Rely on -1 as separator in yyrhs, instead of 0.
12500 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
12501 twice `Now at end of input', therefore there are two lines less to
12504 2001-12-27 Akim Demaille <akim@epita.fr>
12506 * tests/regression.at (Unresolved SR Conflicts):
12507 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
12510 2001-12-27 Akim Demaille <akim@epita.fr>
12512 * src/LR0.c (new_state): Recognize the final state by the fact it
12513 is reached by eoftoken.
12514 (insert_start_shifting_state, insert_eof_shifting_state)
12515 (insert_accepting_state, augment_automaton): Remove, since now
12516 these states are automatically computed from the initial state.
12517 (generate_states): Adjust.
12518 * src/print.c: When reporting a rule number to the user, substract
12519 1, so that the axiom rule is rule 0, and the first user rule is 1.
12520 * src/reduce.c: Likewise.
12521 * src/print_graph.c (print_core): For the time being, just as for
12522 the report, depend upon --trace-flags to dump the full set of
12524 * src/reader.c (readgram): Once the grammar read, insert the rule
12525 0: `$axiom: START-SYMBOL $'.
12526 * tests/set.at: Adjust: rule 0 is now displayed, and since the
12527 number of the states has changed (the final state is no longer
12528 necessarily the last), catch up.
12530 2001-12-27 Akim Demaille <akim@epita.fr>
12532 Try to make the use of the eoftoken valid. Given that its value
12533 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
12534 is used instead of > 0 where appropriate, (ii), depend upon nritems
12535 instead of the 0-sentinel.
12537 * src/gram.h, src/gram.c (nritems): New.
12538 Expected to be duplication of nitems, but for the time being...
12539 * src/reader.c (packgram): Assert nritems and nitems are equal.
12540 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
12541 * src/closure.c (print_closure, print_fderives): Likewise.

12548 * src/main.c (main): If there are complains after grammar
12549 reductions, then output the report anyway if requested, then die.
12550 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
12551 * src/reader.c (eoftoken): New.
12552 (parse_token_decl): If the token being defined has value `0', it
12554 (packsymbols): No longer hack `tags' to insert `$' by hand.
12555 Be sure to preserve the value of the eoftoken.
12556 (reader): Make sure eoftoken is defined.
12557 Initialize nsyms to 0: now eoftoken is created just like the others.
12558 * src/print.c (print_grammar): Don't special case the eof token.
12559 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
12560 lie anyway, albeit pleasant.
12561 * tests/calc.at: Exercise error messages with eoftoken.
12562 Change the grammar so that empty input is invalid.
12563 Adjust expectations.
12564 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
12566 2001-12-27 Akim Demaille <akim@epita.fr>
12568 * configure.in: Check the protos of strchr ans strspn.
12569 Replace strchr if needed.
12570 * src/system.h: Provide the protos of strchr, strspn and memchr if
12572 * lib/strchr.c: New.
12573 * src/reader.c (symbols_save): Use strchr.
12575 2001-12-27 Akim Demaille <akim@epita.fr>
12577 * src/print.c, src/print_graph.c (escape): New.
12578 Use it to quote the TAGS outputs.
12579 * src/print_graph.c (print_state): Now errors are in red, and
12580 reductions in green.
12581 Prefer high to wide: output the state number on a line of its own.
12583 2001-12-27 Akim Demaille <akim@epita.fr>
12585 * src/state.h, src/state.c (reductions_new): New.
12586 * src/LR0.c (set_state_table): Let all the states have a
12587 `reductions', even if reduced to 0.

12597 even if reduced to 0.
12598 * src/print.c (print_errs, print_reductions): Adjust.
12599 * src/output.c (output_actions, action_row): Adjust.

12639 * src/output.c (output): Adjust.
12640 * src/reader.c (parse_braces): New, factoring...
12641 (copy_action, copy_guard): these two which are renamed as...
12642 (parse_action, parse_guard): these.
12643 As a voluntary consequence, using braces around guards is now
12646 2001-12-27 Akim Demaille <akim@epita.fr>
12648 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
12649 * src/reader.c (symbol_list): `guard' and `guard_line' are new
12651 (symbol_list_new): Adjust.
12652 (copy_action): action_line is the first line, not the last.
12653 (copy_guard): Just as for actions, store the `action' only, not
12654 the switch/case/break flesh.
12655 Don't parse the user action that might follow the guard, let...
12656 (readgram): do it, i.e., now, there can be an action after a
12658 In other words the guard is just explicitly optional.
12659 (packgram): Adjust.
12660 * src/output.c (guards_output): New.
12661 (output_parser): Call it when needed.
12662 (output): Also free the guard and attrs obstacks.
12663 * src/files.c, src/files.h (obstack_save): Remove.
12664 (output_files): Remove.
12665 As a result, if one needs the former `.act' file, using an
12666 appropriate skeleton which requires actions and guards is now
12668 * src/main.c (main): Adjust.
12669 * tests/semantic.at: New.
12670 * tests/regression.at: Use `input.y' as input file name.
12671 Avoid 8+3 problems by requiring input.c when the test needs the

12676 * src/reader.c (symbol_list_new): Be sure to initialize all the
12679 2001-12-27 Akim Demaille <akim@epita.fr>
12681 All the hacks using a final pseudo state are now useless.
12683 * src/LR0.c (set_state_table): state_table holds exactly nstates.
12684 * src/lalr.c (nLA): New.
12685 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
12686 instead of lookaheadsp from the pseudo state (nstate + 1).
12688 2001-12-27 Akim Demaille <akim@epita.fr>
12690 * src/output.c (action_row, token_actions): Use a state_t instead
12691 of a integer, and nlookaheads instead of the following state's
12694 2001-12-27 Akim Demaille <akim@epita.fr>
12696 * src/conflicts.c (log_resolution, flush_shift)
12697 (resolve_sr_conflict, set_conflicts, solve_conflicts)
12698 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
12699 (conflicts_print, print_reductions): Use a state_t instead of an
12700 integer when referring to a state.
12701 As much as possible, depend upon nlookaheads, instead of the
12702 `lookaheadsp' member of the following state (since lookaheads of
12703 successive states are successive, the difference between state n + 1
12704 and n served as the number of lookaheads for state n).
12705 * src/lalr.c (add_lookback_edge): Likewise.
12706 * src/print.c (print_core, print_actions, print_state)
12707 (print_results): Likewise.
12708 * src/print_graph.c (print_core, print_actions, print_state)
12709 (print_graph): Likewise.
12710 * src/conflicts.h: Adjust.
12712 2001-12-27 Akim Demaille <akim@epita.fr>
12714 * src/bison.hairy: Formatting/comment changes.
12716 Remove `register' indications.
12717 Add plenty of `static'.
12719 2001-12-27 Akim Demaille <akim@epita.fr>
12721 * src/output.c (prepare): Drop the muscle `ntbase' which
12722 duplicates ntokens.
12723 * src/bison.simple: Formatting/comment changes.
12724 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
12725 is an undocumented synonym.
12727 2001-12-22 Akim Demaille <akim@epita.fr>
12729 * src/output.c (output_table_data): Change the prototype to use
12730 `int' for array ranges: some invocations do pass an int, not a
12732 Reported by Wayne Green.
12734 2001-12-22 Akim Demaille <akim@epita.fr>
12736 Some actions of web2c.y are improperly triggered.
12737 Reported by Mike Castle.
12739 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
12740 * tests/regression.at (Web2c): Rename as...
12741 (Web2c Report): this.
12742 (Web2c Actions): New.
12744 2001-12-22 Akim Demaille <akim@epita.fr>
12746 Reductions in web2c.y are improperly reported.
12747 Reported by Mike Castle.
12749 * src/conflicts.c (print_reductions): Fix.
12750 * tests/regression.at (Web2c): New.
12752 2001-12-18 Akim Demaille <akim@epita.fr>
12754 Some host fail on `assert (!"foo")', which expands to
12755 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
12756 Reported by Nelson Beebee.
12758 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
12759 `#define it_succeeded 0' and `assert (it_succeeded)'.
12761 2001-12-17 Marc Autret <autret_m@epita.fr>
12763 * src/bison.simple: Don't hard code the skeleton line and filename.
12764 * src/output.c (output_parser): Rename 'line' as 'output_line'.
12765 New line counter 'skeleton_line' (skeleton-line muscle).
12767 2001-12-17 Paul Eggert <eggert@twinsun.com>
12769 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
12770 YYDEBUG must be defined to a nonzero value.
12772 * src/bison.simple (yytname): Do not assume that the user defines
12773 YYDEBUG to a properly parenthesized expression.
12775 2001-12-17 Akim Demaille <akim@epita.fr>
12777 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
12778 nlookaheads is a new member.
12780 * src/lalr.h (nlookaheads): Remove this orphan declaration.
12781 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
12784 2001-12-17 Akim Demaille <akim@epita.fr>
12786 * src/files.h, src/files.c (open_files, close_files): Remove.
12787 * src/main.c (main): Don't open/close files, nor invoke lex_free,
12789 * src/reader.c (reader): Do it.
12791 2001-12-17 Akim Demaille <akim@epita.fr>
12793 * src/conflicts.c (print_reductions): Formatting changes.
12795 2001-12-17 Akim Demaille <akim@epita.fr>
12797 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
12798 (flush_reduce): New.
12799 (resolve_sr_conflict): Adjust.
12801 2001-12-17 Akim Demaille <akim@epita.fr>
12803 * src/output.c (output_obstack): Be static and rename as...
12804 (format_obstack): this, to avoid any confusion with files.c's
12806 * src/reader.h (muscle_obstack): Move to...
12807 * src/output.h: here, since it's defined in output.c.
12809 2001-12-17 Akim Demaille <akim@epita.fr>
12811 * src/output.c (action_row, save_column, default_goto)
12812 (sort_actions, matching_state, pack_vector): Better variable
12815 2001-12-17 Akim Demaille <akim@epita.fr>
12817 * src/output.c: Various formatting changes.
12819 2001-12-17 Akim Demaille <akim@epita.fr>
12821 * src/files.c (output_files): Free the output_obstack.
12822 * src/main.c (main): Call print and print_graph conditionally.
12823 * src/print.c (print): Work unconditionally.
12824 * src/print_graph.c (print_graph): Work unconditionally.
12825 * src/conflicts.c (log_resolution): Output only if verbose_flag.
12827 2001-12-16 Marc Autret <autret_m@epita.fr>
12829 * src/output.c (actions_output): Fix. When we use %no-lines,
12830 there is one less line per action.
12832 2001-12-16 Marc Autret <autret_m@epita.fr>
12834 * src/bison.simple: Remove a useless #line directive.
12835 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
12836 * src/output.c (get_lines_number): New.
12837 (output_parser): Adjust, now takes care about the lines of a
12839 Fix line numbering.
12840 (actions_output): Computes the number of lines taken by actions.
12841 (output_master_parser): Insert new skeleton which is the name of
12842 the output parser file name.
12844 2001-12-15 Marc Autret <autret_m@epita.fr>
12846 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
12848 2001-12-15 Marc Autret <autret_m@epita.fr>
12850 * src/output.c (output_gram): Keep track of the hairy one.
12852 2001-12-15 Akim Demaille <akim@epita.fr>
12854 Make `make distcheck' work.
12856 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
12857 system.h which uses libgettext.h.
12859 2001-12-15 Akim Demaille <akim@epita.fr>
12861 * src/nullable.c (set_nullable): Useless rules must be skipped,
12862 otherwise, since we range over their symbols, we might look at a
12863 nonterminal which no longer ``exists'', i.e., it is not counted in
12864 `nvars', hence we overflow our arrays.
12866 2001-12-15 Akim Demaille <akim@epita.fr>
12868 The header can also be produced directly, without any obstack!
12871 * src/files.c, src/files.h (defines_obstack): Remove.
12872 (compute_header_macro): Global.
12873 (defines_obstack_save): Remove.
12874 * src/reader.c (parse_union_decl): No longer output to
12875 defines_obstack: its content can be found in the `stype' muscle
12877 (output_token_translations): Merge into...
12878 (symbols_output): this.
12880 (symbols_save): this.
12882 * src/output.c (header_output): New.
12885 2001-12-15 Akim Demaille <akim@epita.fr>
12887 * src/reader.c (parse_union_decl): Instead of handling two obstack
12888 simultaneously, use one to define the `stype' muscle, and use the
12889 value of the latter to fill defines_obstack.
12890 (copy_comment): Remove.
12891 (copy_comment2): Work for a single obstack.
12893 (copy_comment): this.
12895 2001-12-15 Akim Demaille <akim@epita.fr>
12897 * src/lex.c, src/lex.h (xgetc): No longer static.
12898 * src/reader.c (parse_union_decl): Revamp.
12900 2001-12-15 Akim Demaille <akim@epita.fr>
12902 Still making progress in separating Bison into (i) input, (ii)
12903 process, (iii) output: now we can directly output the parser file
12904 without using table_obstack at all.
12906 * src/files.c, src/files.h (table_obstack): Bye bye.
12907 (parser_file_name): New.
12908 * src/files.c (compute_output_file_names): Compute it.
12909 * src/output.c (actions_output, output_parser)
12910 (output_master_parser): To a file instead of an obstack.
12912 2001-12-15 Akim Demaille <akim@epita.fr>
12914 Attach actions to rules, instead of pre-outputting them to
12917 * src/gram.h (rule_t): action and action_line are new members.
12918 * src/reader.c (symbol_list): Likewise.
12919 (copy_action): Save the actions within the rule.
12920 (packgram): Save them in rule_table.
12921 * src/output.c (actions_output): New.
12922 (output_parser): Use it on `%%actions'.
12923 (output_rule_data): Don't free rule_table.
12925 (prepare): Don't save the `action' muscle.
12926 * src/bison.simple: s/%%action/%%actions/.
12928 2001-12-15 Akim Demaille <akim@epita.fr>
12930 * src/reader.c (copy_action): When --yacc, don't append a `;'
12931 to the user action: let it fail if lacking.
12932 Suggested by Arnold Robbins and Tom Tromey.
12934 2001-12-14 Akim Demaille <akim@epita.fr>
12936 * src/lex.c (literalchar): Simply return the char you decoded, non
12937 longer mess around with obstacks and int pointers.
12938 Adjust all callers.
12940 2001-12-14 Akim Demaille <akim@epita.fr>
12942 * src/lex.c (literalchar): Don't escape the special characters,
12943 just decode them, and keep them as char (before, eol was output as
12944 the 2 char string `\n' etc.).
12945 * src/output.c (output_rule_data): Use quotearg to output the
12948 2001-12-13 Paul Eggert <eggert@twinsun.com>
12950 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
12951 Do not infringe on the global user namespace when using C++.
12952 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
12953 All uses of `fprintf' and `stderr' changed.
12955 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
12957 2001-12-13 Akim Demaille <akim@epita.fr>
12959 The computation of nullable is broken: it doesn't handle empty
12962 * tests/torture.at (GNU AWK Grammar): New.
12963 * tests/sets.at (Nullable): New.
12964 * src/nullable.c (set_nullable): Instead of blindly looping over
12965 `ritems', loop over the rules, and then over their rhs's.
12967 Work around Autotest bugs.
12969 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
12970 frame, because Autotest understand lines starting with a `+' as
12971 traces from the shell. Then, they are not processed properly.
12972 Admittedly an Autotest bug, but we don't have time to wait for
12973 Autotest to catch up.
12974 * tests/regression.at (Broken Closure): Adjust to the new table
12977 * tests/sets.at: here.
12979 2001-12-13 Akim Demaille <akim@epita.fr>
12981 * src/closure.c (closure): Use nrules instead of playing tricks
12982 with BITS_PER_WORD.
12984 2001-12-13 Akim Demaille <akim@epita.fr>
12986 * src/print.c (print_actions): Output the handling of `$' as the
12987 traces do: shifting the token EOF. Before EOF was treated as a
12989 * tests/regression.at: Adjust some tests.
12990 * src/print_graph.c (print_core): Complete the set of items via
12991 closure. The next-to-final and final states are still unsatisfying,
12992 but that's to be addressed elsewhere.
12993 No longer output the rule numbers, but do output the state number.
12994 A single loop for the shifts + gotos is enough, but picked a
12995 distinct color for each.
12996 (print_graph): Initialize and finalize closure.
12998 2001-12-13 Akim Demaille <akim@epita.fr>
13000 * src/reader.c (readgram): Remove dead code, an strip useless
13002 (get_type): Remove, unused.
13004 2001-12-12 Akim Demaille <akim@epita.fr>
13006 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
13007 on that of lib/error.c.
13009 2001-12-12 Akim Demaille <akim@epita.fr>
13011 Some hosts don't like `/' in includes.
13013 * src/system.h: Include libgettext.h without qualifying the path.
13014 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
13017 2001-12-11 Marc Autret <autret_m@epita.fr>
13019 * src/output.c (output_parser): Remove useless muscle.
13021 2001-12-11 Marc Autret <autret_m@epita.fr>
13023 * src/bison.simple: Remove #line just before %%epilogue. It
13024 is now handled in ...
13025 * src/reader.c (read_additionnal_code): Add the output of a
13026 #line for the epilogue.
13028 2001-12-10 Marc Autret <autret_m@epita.fr>
13030 * src/reader.c (copy_definition): Re-use CPP-outed code which
13031 replace precedent remove.
13032 * src/bison.simple: Remove #line before %%prologue because
13033 %%input-line is wrong at this time.
13035 2001-12-10 Marc Autret <autret_m@epita.fr>
13037 * src/reader.c (symbols_output): Clean up.
13038 * src/output.c (output_gram, output): Clean up.
13040 2001-12-10 Akim Demaille <akim@epita.fr>
13042 * src/lalr.c (initialize_lookaheads): New. Extracted from...
13043 * src/LR0.c (set_state_table): here.
13044 * src/lalr.c (lalr): Call it.
13046 2001-12-10 Akim Demaille <akim@epita.fr>
13048 * src/state.h (shifts): Remove the `number' member: shifts are
13049 attached to state, hence no longer need to be labelled with a
13052 2001-12-10 Akim Demaille <akim@epita.fr>
13054 Now that states have a complete set of members, the linked list of
13055 shifts is useless: just fill directly the state's shifts member.
13057 * src/state.h (shifts): Remove the `next' member.
13058 * src/LR0.c (first_state, last_state): Remove.
13059 Adjust the callers.
13060 (augment_automaton): Don't look for the shifts that must be added
13061 a shift on EOF: it is those of the state we looked for! But now,
13062 since shifts are attached, it is no longer needed to looking
13063 merely by its id: its number.
13065 2001-12-10 Akim Demaille <akim@epita.fr>
13067 * src/LR0.c (augment_automaton): Better variable locality.
13068 Remove an impossible branch: if there is a state corresponding to
13069 the start symbol being shifted, then there is shift for the start
13070 symbol from the initial state.
13072 2001-12-10 Akim Demaille <akim@epita.fr>
13074 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
13075 only when appropriate: when insert_start_shifting_state' is not
13077 * tests/regression.at (Rule Line Numbers): Adjust.
13079 2001-12-10 Akim Demaille <akim@epita.fr>
13081 * src/LR0.c (augment_automaton): Now that all states have shifts,
13082 merge the two cases addition shifts to the initial state.
13084 2001-12-10 Akim Demaille <akim@epita.fr>
13086 * src/lalr.c (set_state_table): Move to...
13088 * src/lalr.c (lalr): Don't call it...
13089 * src/LR0.c (generate_states): do it.
13090 * src/LR0.h (first_state): Remove, only the table is used.
13092 2001-12-10 Akim Demaille <akim@epita.fr>
13094 * src/LR0.h (first_shift, first_reduction): Remove.
13095 * src/lalr.c: Don't use first_shift: find shifts through the
13098 2001-12-10 Akim Demaille <akim@epita.fr>
13100 * src/LR0.c: Attach shifts to states as soon as they are
13102 * src/lalr.c (set_state_table): Instead of assigning shifts to
13103 state, just assert that the mapping was properly done.
13105 2001-12-10 Akim Demaille <akim@epita.fr>
13107 * src/LR0.c (insert_start_shift): Rename as...
13108 (insert_start_shifting_state): this.
13109 (insert_eof_shifting_state, insert_accepting_state): New.
13110 (augment_automaton): Adjust.
13111 Better locality of the variables.
13112 When looking if the start_symbol is shifted from the initial
13113 state, using `while (... symbol != start_symbol ...)' sounds
13114 better than `while (... symbol < start_symbol ...)': If fail
13115 to see how the order between symbols could be relevant!
13117 2001-12-10 Akim Demaille <akim@epita.fr>
13119 * src/getargs.h: Don't declare `spec_name_prefix' and
13120 `spec_file_prefix', declared by src/files.h.
13121 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
13122 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
13123 * src/output.c (prepare): Adjust.
13124 * src/reader.c (symbols_output): Likewise.
13125 * src/vmsgetargs.c: Vaguely adjust, but who cares?
13127 2001-12-10 Akim Demaille <akim@epita.fr>
13129 * src/muscle_tab.c (muscle_init): NULL is a better default than
13132 2001-12-10 Akim Demaille <akim@epita.fr>
13134 * src/reader.c (reader): Calling symbols_output once is enough.
13136 2001-12-10 Akim Demaille <akim@epita.fr>
13138 Now that states have a complete set of members, the linked list of
13139 reductions is useless: just fill directly the state's reductions
13142 * src/state.h (struct reductions): Remove member `number' and
13144 * src/LR0.c (first_reduction, last_reduction): Remove.
13145 (save_reductions): Don't link the new reductions, store them in
13147 * src/lalr.c (set_state_table): No need to attach reductions to
13148 states, it's already done.
13149 * src/output.c (output_actions): No longer free the shifts, then
13150 the reductions, then the states: free all the states and their
13153 2001-12-10 Akim Demaille <akim@epita.fr>
13155 * src/options.c (OPTN, DRTV, BOTH): New.
13156 (option_table): Use them.
13158 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
13159 the job of system.h.
13160 * src/options.c: Don't include stdio.h and xalloc.h for the same
13163 2001-12-10 Akim Demaille <akim@epita.fr>
13165 * src/output.c (output, prepare): Make sure the values of the
13166 muscles `action' and `prologue' are 0-terminated.
13168 2001-12-10 Akim Demaille <akim@epita.fr>
13170 Clean up GCC warnings.
13172 * src/reader.c (copy_action): `buf' is not used.
13173 (parse_skel_decl): Be static.
13174 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
13175 * src/options.h (create_long_option_table): Have a real prototype.
13176 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
13177 (hash_delete_at): Return const void *.
13178 Adjust casts to preserve the const.
13180 2001-12-10 Akim Demaille <akim@epita.fr>
13182 * configure.in: Require 2.52g.
13183 M4 is not needed, but AUTOM4TE is.
13184 * m4/m4.m4: Remove.
13185 * tests/Makefile.am: Adjust.
13187 2001-12-10 Akim Demaille <akim@epita.fr>
13189 One structure for states is enough, even though theoretically
13190 there are LR(0) states and LALR(1) states.
13192 * src/lalr.h (state_t): Remove.
13193 (state_table): Be state_t **, not state_t *.
13194 * src/state.h (core, CORE_ALLOC): Rename as...
13195 (state_t, STATE_ALLOC): this.
13196 Add the LALR(1) members: shifts, reductions, errs.
13197 * src/LR0.c (state_table): Rename as...
13198 (state_hash): this, to avoid name clashes with the global
13200 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
13201 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
13203 2001-12-10 Akim Demaille <akim@epita.fr>
13205 Bison dumps core on bash.y.
13206 Reported by Pascal Bart.
13208 * src/warshall.c (bitmatrix_print): New.
13210 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
13211 j must be the outer loop.
13212 * tests/regression.at (Broken Closure): New.
13214 2001-12-05 Akim Demaille <akim@epita.fr>
13216 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
13218 Reported by Peter Hamorsky.
13220 2001-12-05 Akim Demaille <akim@epita.fr>

13223 (resolve_sr_conflict): Adjust.
13224 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
13226 (state_t.reductions, state_t.shifts): this.
13228 2001-12-05 Akim Demaille <akim@epita.fr>
13230 * src/reduce.c (reduce_grammar_tables): No longer disable the
13231 removal of useless rules via CPP but via `if (0)', so that the
13232 compiler still check the code is valid.
13233 For instance, it should have noticed `rline' no longer exists: use
13234 the `line' member of rule_t.
13235 * src/gram.c (dummy, rline): Remove, unused.
13237 2001-12-05 Akim Demaille <akim@epita.fr>
13239 * src/output.c (pack_vector): Use assert, not berror.
13240 * src/main.c (berror): Remove, unused.
13242 2001-12-05 Akim Demaille <akim@epita.fr>
13244 New experimental feature: if --verbose --trace output all the
13245 items of a state, not only its kernel.
13247 * src/print.c (print_core): If `trace_flag', then invoke closure
13248 before outputting the items of the state (print_core is no longer
13249 a correct name them).
13250 (print_results): Invoke new_closure/free_closure if needed.
13252 2001-12-05 Akim Demaille <akim@epita.fr>
13254 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
13255 * src/closure.c, src/closure.h (itemsetsize): Rename as...
13256 (nitemset): for consistency with the rest of the project.
13258 2001-12-05 Akim Demaille <akim@epita.fr>
13260 * src/closure.c (print_closure): Improve.
13261 (closure): Use it for printing input and output.
13263 2001-12-05 Akim Demaille <akim@epita.fr>
13265 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
13266 indexed by nonterminals.
13268 2001-12-05 Akim Demaille <akim@epita.fr>
13270 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of

13286 2001-12-05 Akim Demaille <akim@epita.fr>
13288 * src/output.c (action_row): De-obfuscate
13289 using the good o' techniques: arrays not pointers, variable
13290 locality, BITISSET, RESETBIT etc.
13292 2001-12-05 Akim Demaille <akim@epita.fr>
13294 Pessimize the code to simplify it: from now on, all the states
13295 have a valid SHIFTS, which NSHIFTS is possibly 0.
13297 * src/LR0.c (shifts_new): Be global and move to..
13298 * src/state.c, src/state.h: here.
13299 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
13300 * src/print_graph: Adjust.
13302 2001-12-05 Akim Demaille <akim@epita.fr>
13304 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
13305 * src/conflicts.c: Use it.
13306 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
13307 incorrectly ``simplified''.
13309 2001-12-05 Akim Demaille <akim@epita.fr>
13311 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
13312 using the good o' techniques: arrays not pointers, variable
13313 locality, BITISSET, RESETBIT etc.
13315 2001-12-05 Akim Demaille <akim@epita.fr>
13317 * src/state.h (SHIFT_SYMBOL): New.
13318 * src/conflicts.c: Use it to deobfuscate.

13322 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
13323 (print_reductions): De-obfuscate using the good o' techniques:

13343 2001-12-05 Akim Demaille <akim@epita.fr>
13345 * src/conflicts.c (print_reductions): Improve variable locality.
13347 2001-12-05 Akim Demaille <akim@epita.fr>
13349 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
13350 * src/lalr.c: Use them.
13352 2001-12-05 Akim Demaille <akim@epita.fr>
13354 * src/LR0.c (augment_automaton): Formatting changes.
13355 Better variable locality.

13359 * src/lalr.c (matrix_print): New.
13360 (transpose): Use it.

13363 2001-12-05 Akim Demaille <akim@epita.fr>
13365 * src/lalr.c (maxrhs): Move to...
13366 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
13367 * src/lalr.c (build_relations): Adjust.
13369 2001-12-05 Akim Demaille <akim@epita.fr>
13371 * src/lalr.c (transpose): Free the memory allocated to the
13372 argument, as it is replaced by the results by the unique caller.
13373 (build_relations): Merely invoke transpose: it handles the memory
13375 Improve variable locality.
13376 Avoid variables used as mere abbreviations.
13377 (compute_lookaheads): Use arrays instead of pointers.
13379 2001-12-05 Akim Demaille <akim@epita.fr>
13381 * src/lalr.c (initialize_F): Improve variable locality.
13382 Avoid variables used as mere abbreviations.
13384 2001-12-05 Akim Demaille <akim@epita.fr>
13386 * src/derives.c (print_derives): Display the ruleno.
13387 * src/lalr.c (initialize_F, transpose): Better variable locality

13395 2001-12-05 Akim Demaille <akim@epita.fr>
13397 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
13398 the handling of squeue.
13399 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
13401 2001-12-05 Akim Demaille <akim@epita.fr>
13403 Because useless nonterminals are now kept alive (instead of being
13404 `destroyed'), we now sometimes examine them, and store information
13405 related to them. Hence we need to know their number, and adjust
13406 memory allocations.
13408 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
13410 * src/LR0.c (allocate_itemsets): The memory allocated to
13411 `symbol_count' was used for two different purpose: once to count
13412 the number of occurrences of each symbol, and later reassigned to
13413 `shift_symbol', containing the symbol that can be shifted from a
13415 Deobfuscate, i.e., allocate, use and free `symbol_count' here
13417 (new_itemsets): Allocate `shift_symbol' here.
13418 (allocate_itemsets): symbol_count includes useless nonterminals.
13419 Make room for them.
13420 (free_storage): Use `free', not `XFREE', for pointers that cannot
13423 2001-12-05 Akim Demaille <akim@epita.fr>
13425 * src/nullable.c (set_nullable): Deobfuscate the handling of
13427 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
13429 2001-12-05 Akim Demaille <akim@epita.fr>
13431 * src/gram.c, src/gram.h (ritem_print): New.
13432 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
13433 (This useless function was defined only to work around VMS linkers
13434 that can't handle compilation units with variables only).
13435 * src/reduce.c (dump_grammar): Use it to trace the construction of
13438 2001-12-04 Paul Eggert <eggert@twinsun.com>
13440 * src/bison.simple (union yyalloc): Change member names
13441 to be the same as the stack names.
13442 (yyparse): yyptr is now union yyalloc *, not char *.
13443 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
13444 and may generate better code on some machines.
13445 (yystpcpy): Use prototype if __STDC__ is defined, not just
13446 if __cplusplus is defined.
13448 2001-11-30 Akim Demaille <akim@epita.fr>
13450 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
13451 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
13452 Gettext doesn't compile cleanly, and dies with -Werror.
13453 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
13454 Include WARNING_CFLAGS here.
13455 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
13456 before being defined.
13458 2001-11-27 Paul Eggert <eggert@twinsun.com>
13460 * lib/quotearg.h (quotearg_n, quotearg_n_style):
13461 First arg is int, not unsigned.
13462 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
13463 (SIZE_MAX, UINT_MAX): New macros.
13464 (quotearg_n_options): Abort if N is negative.
13465 Avoid overflow check on hosts where size_t is 64 bits and int
13466 is 32 bits, as overflow is impossible there.
13467 Fix off-by-one typo that caused unnecessary reallocation.
13469 2001-11-29 Paul Eggert <eggert@twinsun.com>
13471 Name space cleanup in generated parser.
13473 * doc/bison.texinfo (Bison Parser): Discuss system headers
13474 and their effect on the user name space.
13476 * src/bison.simple:
13477 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
13478 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
13479 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
13481 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
13482 on user names when possible.
13484 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
13485 Simplify test for whather <alloca.h> exists.
13487 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
13489 (<stdio.h>): Include if YYDEBUG.
13491 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
13492 ! defined (yyoverflow) && ! defined (yymemcpy).
13494 (yymemcpy, yyparse): Rename local variables as needed so that
13495 they all begin with 'yy'.
13497 (yystrlen, yystpcpy): New functions.
13499 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
13502 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
13503 instead of relying on string.h functions. Use YYSTACK_ALLOC
13504 and YYSTACK_FREE instead of malloc and free.
13506 2001-11-30 Akim Demaille <akim@epita.fr>
13508 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
13509 before their first uses.

13516 2001-11-30 Akim Demaille <akim@epita.fr>
13518 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
13519 if body instead of `;' to pacify GCC's warnings.
13521 2001-11-30 Akim Demaille <akim@epita.fr>
13523 Instead of mapping the LHS of unused rules to -1, keep the LHS
13524 valid, but flag the rules as invalid.
13526 * src/gram.h (rule_t): `useful' is a new member.
13527 * src/print.c (print_grammar): Adjust.
13528 * src/derives.c (set_derives): Likewise.
13529 * src/reader.c (packgram, reduce_output): Likewise.
13530 * src/reduce.c (reduce_grammar_tables): Likewise.
13531 * tests/reduce.at (Underivable Rules, Useless Rules): New.
13533 2001-11-30 Akim Demaille <akim@epita.fr>

13540 2001-11-30 Akim Demaille <akim@epita.fr>
13542 * src/reduce.c (nonterminals_reduce): Instead of throwing away
13543 useless nonterminals, move them at the end of the symbol arrays.
13544 (reduce_output): Adjust.
13545 * tests/reduce.at (Useless Nonterminals): Adjust.
13547 2001-11-30 Akim Demaille <akim@epita.fr>

13557 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
13558 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
13560 (union yyalloc): New type.
13561 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
13562 an arbitrary restriction on hosts where size_t is wider than int.
13564 (yyparse): Don't dump core if alloca or malloc fails; instead, report
13565 a parser stack overflow. Allocate just one block of memory for all
13566 three stacks, instead of allocating three blocks; this typically is
13567 faster and reduces fragmentation.
13569 Do not limit the number of items in the stack to a value that fits
13570 in 'int', as this is an arbitrary limit on hosts with 64-bit
13571 size_t and 32-bit int.
13573 2001-11-29 Marc Autret <autret_m@epita.fr>
13575 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
13576 of defining YYERROR_VERBOSE.

13621 2001-11-28 Akim Demaille <akim@epita.fr>
13623 * src/closure.c (closure): `b' and `ruleno' denote the same value:
13626 2001-11-28 Akim Demaille <akim@epita.fr>
13628 * src/closure.c (closure): Instead of looping over word in array
13629 then bits in words, loop over bits in array.
13631 2001-11-28 Akim Demaille <akim@epita.fr>
13633 * src/closure.c (closure): No longer optimize the special case
13634 where all the bits of `ruleset[r]' are set to 0, to make the code
13637 2001-11-28 Akim Demaille <akim@epita.fr>
13639 * src/closure.c (closure): `r' and `c' are new variables, used to
13640 de-obfuscate accesses to RULESET and CORE.

13656 From Enrico Scholz.
13658 2001-11-27 Paul Eggert <eggert@twinsun.com>
13660 * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to
13661 use alloca when we didn't want to, and vice versa.
13663 2001-11-27 Marc Autret <autret_m@epita.fr>
13665 * src/muscle_tab.c (muscle_init): Remove 'verbose' muscle

15382 * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
15383 New, from fileutils 4.0.37.
15384 * configure.in: Require Autoconf 2.49c. I took some time before
15385 making this decision. This is the only way out for portability
15386 issues in Bison, it would mean way too much duplicate effort to

15408 s/\bENDFILE\b/tok_eof/g;
15409 s/\bIDENTIFIER\b/tok_identifier/g;
15411 Let them be enums, not #define, to ease debugging.

15435 introduces a guaranteed SEGV for semantic parsers.
15436 * doc/bison.texinfo: Document them.
15437 * tests/suite.at: Exercise these %options.
15439 2000-12-20 Akim Demaille <akim@epita.fr>

15657 Use `obstack_save'.
15658 * src/main.c (main): Don't use `atexit' to register `done', since
15659 it no longer has to remove tmp files, just call `output_files'
15660 when there are no errors.

15787 2000-10-02 Akim Demaille <akim@epita.fr>
15789 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
15792 2000-10-02 Akim Demaille <akim@epita.fr>
15794 * src/derives.c, src/print.c, src/reduce.c: To ease the
15795 translation, move some `\n' out of the translated strings.
15797 2000-10-02 Akim Demaille <akim@epita.fr>
15799 The location tracking mechanism is precious for parse error
15800 messages. Nevertheless, it is enabled only when `@n' is used in
15801 the grammar, which is a different issue (you can use it in error
15802 message, but not in the grammar per se). Therefore, there should
15803 be another means to enable it.
15805 * src/getargs.c (getargs): Support `--locations'.
15806 (usage): Report it.
15807 * src/getargs.h (locationsflag): Export it.
15808 * src/lex.c (percent_table): Support `%locations'.
15809 * src/reader.c (yylsp_needed): Remove this variable, now replaced
15810 with `locationsflag'.
15811 * doc/bison.texinfo: Document `--locations' and `%locations'.
15813 * tests/calc.m4: Test it.
15815 For regularity of the names, replace each
15816 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
15817 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
15818 In addition replace each `flag' with `_flag'.
15820 2000-10-02 Akim Demaille <akim@epita.fr>
15822 Also test parse error messages, including with YYERROR_VERBOSE.
15824 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
15826 Use it to check the computations.
15827 Use it to check `nonassoc' is honored.
15828 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
15829 `--yyerror-verbose'.
15830 (_AT_CHECK_CALC): Adjust to this option.
15831 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
15833 2000-10-02 Akim Demaille <akim@epita.fr>
15835 Test also `--verbose', `--defines' and `--name-prefix'. Testing
15836 the latter demonstrates a flaw in the handling of non debugging
15837 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
15838 was used in order to simplify:
15854 unfortunately this leads to a CPP conflict when
15855 `--name-prefix=foo' is used since it produces `#define yydebug
15858 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
15859 (YYDPRINTF): New macro.
15861 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
15863 Also test `--verbose', `--defines' and `--name-prefix'.
15865 2000-10-02 Akim Demaille <akim@epita.fr>
15867 Improve the readability of the produced parsers.
15869 * src/bison.s1: Formatting changes.
15870 Improve the comment related to the `$' mark.
15871 (yydefault): Don't fall through to `yyresume': `goto' there.
15872 * src/output.c (output_parser): When the `$' is met, skip the end
15874 New variable, `number_of_dollar_signs', to check there's exactly
15875 one `$' in the parser skeleton.
15877 2000-10-02 Akim Demaille <akim@epita.fr>
15879 * lib/xstrdup.c: New file, from the fileutils.
15880 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
15881 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
15882 instead of strlen + xmalloc + strcpy.
15883 * src/symtab.c (copys): Remove, use xstrdup instead.
15885 2000-10-02 Akim Demaille <akim@epita.fr>
15887 * src/gram.h (associativity): New enum type which replaces the
15888 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
15889 `right_assoc', `left_assoc' and `non_assoc'.
15890 Adjust all dependencies.
15891 * src/reader.c: Formatting changes.
15892 (LTYPESTR): Don't define it, use it as a literal in
15893 `reader_output_yylsp'.
15894 * src/symtab.h (symbol_class): New enum type which replaces the
15895 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
15896 `sunknown', `stoken and `snterm'.
15898 2000-10-02 Akim Demaille <akim@epita.fr>
15900 * src/getargs.c (fixed_outfiles): Rename as...
15901 (yaccflag): for consistency and accuracy.
15902 Adjust dependencies.
15904 2000-10-02 Akim Demaille <akim@epita.fr>
15906 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
15907 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
15908 difficult and introduced a lot of core dump. It turns out that
15909 Bison used an implementation of `xmalloc' based on `calloc', and
15910 at various places it does depend upon the initialization to 0. I
15911 have not tried to isolate the pertinent places, and all the former
15912 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
15913 someone should address this issue.
15915 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
15916 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

15922 2000-10-02 Akim Demaille <akim@epita.fr>
15924 Various anti-`extern in *.c' changes.
15926 * src/system.h: Include `assert.h'.
15928 2000-10-02 Akim Demaille <akim@epita.fr>
15930 * src/state.h (nstates, final_state, first_state, first_shift)
15931 (first_reduction): Move their exportation from here...
15932 * src/LR0.h: to here.
15933 Adjust dependencies.
15934 * src/getargs.c (statisticsflag): New variable.
15935 Add support for `--statistics'.
15936 Adjust dependencies.
15938 Remove a lot of now useless `extern' statements in most files.

15942 * src/LR0.h: New file.
15945 2000-10-02 Akim Demaille <akim@epita.fr>

15972 Propagate its inclusion.
15973 * src/reduce.c: Topological sort and other formatting changes.
15974 (bool, TRUE, FALSE): Move their definition to...
15975 * src/system.h: here.
15977 2000-10-02 Akim Demaille <akim@epita.fr>
15979 * src/files.c: Formatting changes.
15980 (tryopen, tryclose, openfiles): Rename as...
15981 (xfopen, xfclose, open_files): this.
15982 (stringappend): static.

16006 * src/lalr.c: Formatting changes, topological sorting etc.
16008 2000-10-02 Akim Demaille <akim@epita.fr>
16010 * src/output.c (token_actions): Introduce a temporary array,
16011 YYDEFACT, that makes it possible for this function to use
16012 output_short_table.
16014 2000-10-02 Akim Demaille <akim@epita.fr>
16016 `user_toknums' is output as a `short[]' in `output.c', while it is
16017 defined as a `int[]' in `reader.c'. For consistency with the
16018 other output tables, `user_toknums' is now defined as a table of

16033 * src/output.c (output): Topological sort of the functions, in
16034 order to get rid of the `static' prototypes.
16035 No longer use `register'.

16061 Don't define PARAMS.
16062 * src/system.h: Define PARAMS.
16063 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
16064 purpose of config.h. system.h must not try to fix wrong
16065 definitions in config.h.

16150 (parse_union_decl): Use it.
16151 (get_type, parse_start_decl): Use the same `invalid' message.

16191 complain.c::complain.
16192 (toomany): Remove, use fatal instead.

16194 * src/main.c (main): Register `done' to `atexit'.
16196 * src/getargs.c (usage): More `fputs', less `fprintf'.

16200 * lib/: New directory.
16201 * Makefile.am (SUBDIRS): Adjust.

16224 2000-03-17 Akim Demaille <akim@epita.fr>
16226 * src/Makefile.am (bison.simple): Fix the awk program: quote only
16227 the file name, not the whole `#line LINE FILE'.
16229 2000-03-17 Akim Demaille <akim@epita.fr>
16231 On syntax errors, report the token on which we choked.
16233 * src/bison.s1 (yyparse): In the label yyerrlab, when

16260 * src/reader.c (copy_string): Declare `static inline'. No
16261 problems with inline, since it is checked by configure.
16262 (copy_comment): Likewise.
16264 2000-03-17 Akim Demaille <akim@epita.fr>
16266 * src/reader.c (packsymbols): Formatting changes.

16279 (copy_guard): Likewise.
16281 2000-03-17 Akim Demaille <akim@epita.fr>
16283 Change the handling of @s so that they behave exactly like $s.
16284 There is now a pseudo variable @$ (readble and writable), location
16285 of the lhs of the rule (by default ranging from the location of
16286 the first symbol of the rhs, to the location of the last symbol,
16287 or, if the rhs is empty, YYLLOC).
16289 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
16291 (yyparse): When providing a default semantic action, provide a
16292 default location action.
16293 (after the $): No longer change `*YYLSP', just stack YYLOC the
16294 same way you stack YYVAL.
16295 * src/reader.c (read_declarations): Use warns.
16296 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
16297 (copy_action, case '@'): Likewise.
16298 Use a standard error message, to save useless work from

16319 2000-03-16 Akim Demaille <akim@epita.fr>
16321 * src/bison.s1 [!YYDEBUG]: Define yydebug to 0. This allows to
16322 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
16323 One `#if YYDEBUG' remains, since it uses variables which are

16993 (print_notices): Remove final `.' from error message.
16995 * src/reader.c (reader_output_yylsp):
16997 (readgram): Use `#if 0' around code that accepted %command
16998 inside grammar rules: The documentation doesn't allow it,
16999 and it will fail since the %command processors scan for the next %.
17000 (parse_token_decl): Extended the %token
17001 declaration to allow a multi-character symbol as an alias.
17002 (parse_thong_decl): New function.
17003 (read_declarations): Added %thong declarations.
17004 (read_declarations): Handle NOOP to deal with allowing
17005 % declarations as another means to specify the flags.
17006 (readgram): Allow %prec prior to semantics embedded in a rule.
17007 (skip_to_char, read_declarations, copy_definition)
17008 (parse_token_decl, parse_start_decl, parse_type_decl)
17009 (parse_assoc_decl, parse_union_decl, parse_expect_decl)
17010 (get_type_name, copy_guard, copy_action, readgram)
17011 (get_type, packsymbols): Revised most error messages.
17012 Changed `fatal' to `warnxxx' to avoid aborting for error.
17013 Revised and use multiple warnxxx functions to avoid using VARARGS1.
17014 (read_declarations): Improve the error message for
17015 an invalid character. Do not abort.
17016 (read_declarations, copy_guard, copy_action): Use
17017 printable_version to avoid unprintable characters in printed output.
17018 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
17019 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
17020 Allow the type of a non-terminal can be given
17021 more than once, as long as all specifications give the same type.
17024 (output_headers, output_trailers, output, output_gram)
17025 (output_rule_data): Implement noparserflag variable.
17026 Implement toknumflag variable.
17027 (output): Call reader_output_yylsp to output LTYPESTR.
17029 * src/main.c (main):
17030 If reader sees an error, don't process the grammar.
17031 (fatals): Updated to not use VARARGS1.
17032 (printable_version, int_to_string, warn, warni, warns, warnss)
17033 (warnsss): New error reporting functions. Avoid abort for error.
17036 Added THONG and NOOP for alias processing.
17037 Added SETOPT for the new code that allows setting options with %flags.
17040 Include getopt.h. Add some extern decls.
17041 (safegetc): New function to deal with EOF gracefully.
17042 (literalchar); new function to deal with reading \ escapes.
17043 (lex): Use literalchar.
17044 (lex): Implemented "..." tokens.
17045 (literalchar, lex, parse_percent_token): Made tokenbuffer
17046 always contain the token. This includes growing the token
17047 buffer while reading an integer.
17048 (parse_percent_token): Replaced if-else statement with percent_table.
17049 (parse_percent_token): Added % declarations as another
17050 way to specify the flags -n, -l, and -r. Also added hooks for
17051 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
17052 major changes to files.c.
17053 (lex) Retain in the incoming stream a character following
17055 (skip_white_space, lex): Revised most error messages
17056 and changed fatal to warn to avoid aborting.
17057 (percent_table): Added %thong declarations.
17059 * src/gram.h: Comment changes.
17061 * src/files.c (openfiles, open_extra_files, done):
17063 and actfile file. Handle noparserflag. Both for -n switch.
