  70
  71 2002-05-03  Paul Eggert  <eggert@twinsun.com>
  72
  73         * data/bison.simple (b4_token_defines): Also define YYTOKENTYPE

 157
 158         * src/reader.c (copy_at, copy_dollarm parse_braces, parse_action)
 159         (parse_guard): Rename the formal argument `stack_offset' as
 160         `rule_length', which is more readable.

 162         (copy_at, copy_dollar): Instead of outputting the hard coded
 163         values of $$, $n and so forth, output invocation to b4_lhs_value,
 164         b4_lhs_location, b4_rhs_value, and b4_rhs_location.
 165         Note: this patch partially drops `semantic-parser' support: it
 166         always does `rule_length - n', where semantic parsers ought to
 167         always use `-n'.
 168         * data/bison.simple, data/bison.c++ (b4_lhs_value)
 169         (b4_lhs_location, b4_rhs_value, and b4_rhs_location: New.

 212         between `!' and the command.
 213         Reported by Paul Eggert.
 214
 215 2002-04-24  Robert Anisko  <robert@lrde.epita.fr>
 216
 217         * tests/calc.at: Exercise prologue splitting.
 218
 219         * data/bison.simple, data/bison.c++: Use `b4_pre_prologue' and
 220         `b4_post_prologue' instead of `b4_prologue'.
 221
 222         * src/output.c (prepare): Add the `pre_prologue' and `post_prologue'
 223         muscles.

 227         * src/reader.c (copy_definition): Add a parameter to specify the
 228         obstack to fill, instead of using attrs_obstack unconditionally.
 229         (read_declarations): Pass pre_prologue_obstack to copy_definition if
 230         `%union' has not yet been seen, pass post_prologue_obstack otherwise.

 233
 234         * data/bison.simple: Remove unnecessary commentary and white

 239         YYSTACK_RELOCATE): Do not define if yyoverflow is defined, or
 240         if this is a C++ parser and YYSTYPE or YYLTYPE has nontrivial

 252
 253 2002-04-22  Akim Demaille  <akim@epita.fr>
 254
 255         * src/reduce.c (dump_grammar): Move to...
 256         * src/gram.h, src/gram.c (grammar_dump): here.
 257         Be sure to separate long item numbers.
 258         Don't read the members of a rule's prec if its nil.
 259
 260 2002-04-22  Akim Demaille  <akim@epita.fr>
 261
 262         * src/output.c (table_size, table_grow): New.

 273
 274         * src/reader.c (token_translations_init): 256 is now the default
 275         value for the error token, i.e., it will be assigned another

 277         (reader): Don't force 256 to error.
 278         * doc/bison.texinfo (Symbols): Adjust.
 279         * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR)
 280         (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
 281         etc. instead of 10, 20, 30 (which was used to `jump' over error
 282         (256) and undefined (2)).
 283
 284 2002-04-22  Akim Demaille  <akim@epita.fr>

 290         * src/output.c (GENERATE_OUTPUT_TABLE): New.
 291         Use it to create output_item_number_table and
 292         output_token_number_table.
 293         * src/LR0.c, src/derives.c, src/gram.c, src/gram.h, src/lalr.c,

 302 2002-04-19  Akim Demaille  <akim@epita.fr>
 303
 304         * doc/bison.texinfo (Actions): Make clear that `|' is not the same
 305         as Lex/Flex'.
 306         (Debugging): More details about enabling the debugging features.
 307         (Table of Symbols): Describe $$, $n, @$, and @n.

 313
 314 2002-04-10  Akim Demaille  <akim@epita.fr>
 315
 316         * src/system.h: Rely on HAVE_LIMITS_H.
 317         Suggested by Paul Eggert.
 318
 319 2002-04-09  Akim Demaille  <akim@epita.fr>
 320
 321         * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
 322         full stderr, and strip it according to the bison options, instead
 323         of composing the error message from different bits.
 324         This makes it easier to check for several error messages.
 325         Adjust all the invocations.
 326         Add an invocation exercising the error token.
 327         Add an invocation demonstrating a stupid error message.
 328         (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.
 329         Adjust the tests.
 330         Error message are for stderr, not stdout.
 331
 332 2002-04-09  Akim Demaille  <akim@epita.fr>
 333
 334         * src/gram.h, src/gram.c (error_token_number): Remove, use
 335         errtoken->number.
 336         * src/reader.c (reader): Don't specify the user token number (2)
 337         for $undefined, as it uselessly prevents using it.
 338         * src/gram.h (token_number_t): Move to...
 339         * src/symtab.h: here.
 340         (state_t.number): Is a token_number_t.
 341         * src/print.c, src/reader.c: Use undeftoken->number instead of
 342         hard coded 2.
 343         (Even though this 2 is not the same as above: the number of the
 344         undeftoken remains being 2, it is its user token number which
 345         might not be 2).
 346         * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
 347         `user_token_number_max'.
 348         Output `undef_token_number'.
 349         * data/bison.simple, data/bison.c++: Use them.
 350         Be sure to map invalid yylex return values to
 351         `undef_token_number'.  This saves us from gratuitous SEGV.
 352
 353         * tests/conflicts.at (Solved SR Conflicts)
 354         (Unresolved SR Conflicts): Adjust.
 355         * tests/regression.at (Web2c Actions): Adjust.
 356
 357 2002-04-08  Akim Demaille  <akim@epita.fr>
 358
 359         * data/bison.c++: s/b4_item_number_max/b4_rhs_number_max/.

 368
 369         * src/gram.h (item_number_t): New, the type of item numbers in
 370         RITEM.  Note that it must be able to code symbol numbers as
 371         positive number, and the negation of rule numbers as negative
 372         numbers.
 373         Adjust all dependencies (pretty many).

 387
 388         Trying with bigger grammars shows various phenomena: at 3000 (28Mb
 389         of grammar file) bison is killed by my system, at 2000 (12Mb) bison
 390         passes, but produces negative #line number, once fixed, GCC is
 391         killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
 392         C), it passes.

 520
 521 2002-04-07  Akim Demaille  <akim@epita.fr>

 525
 526         * src/output.c (output_token_translations): Rename as...
 527         (prepare_tokens): this.
 528         In addition to `translate', prepare the muscles `tname' and

 547         new_state.
 548         * src/closure.c (closure): Now that the initial state has its
 549         items properly set, there is no need for a special case when
 550         creating `ruleset'.
 551
 552         As a result, now the rule 0, reducing to $axiom, is visible in the
 553         outputs.  Adjust the test suite.

 586         (reduce_output, dump_grammar): Adjust.
 587         * src/print.c (print_grammar): It is no longer needed to check for
 588         the usefulness of a rule, as useless rules are beyond `nrules + 1'.
 589         * tests/reduce.at (Reduced Automaton): New test.
 590
 591 2002-04-07  Akim Demaille  <akim@epita.fr>
 592
 593         * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
 594         lacking `+ 1' to nrules, Bison reported as useless a token if it
 595         was used solely to set the precedence of the last rule...
 596
 597 2002-04-07  Akim Demaille  <akim@epita.fr>
 598
 599         * data/bison.c++, data/bison.simple: Don't output the current file
 600         name in #line, to avoid useless diffs between two identical

 892
 893         Remove the support for C++ namespace cleanliness; it was
 894         causing more problems than it was curing, since it didn't work
 895         properly on some nonstandard C++ compilers.  This can wait
 896         for a proper C++ parser.
 897
 898         * NEWS: Document this.

 939
 940         * data/bison.c++: Replace some direct m4 expansions by constants.  Be
 941         more consistent when naming methods and variables.  Put preprocessor
 942         directives around tables only needed for debugging.

 988         (guards_output): Check against the guard member of a rule, not the
 989         action member.
 990         Adjust callers.
 991         (output_skeleton): Don't look for the skeleton location, let m4 do
 992         that.
 993         Create `/tmp/muscles.m4'.  This is temporary, a proper temporary
 994         file will be used.
 995         Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
 996         (prepare): Given that for the time being changesyntax is not

1006         * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
1007         instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.

1093         * src/files.c (compute_base_names): Don't map extensions when
1094         the YACC flag is set, use defaults.
1095         Reported by Evgeny Stambulchik.
1096
1097 2002-01-20  Marc Autret  <marc@gnu.org>
1098
1099         * src/system.h: Need to define __attribute__ away for non-GCC
1100         compilers as well (i.e. the vendor C compiler).
1101         Suggested by Albert Chin-A-Young.
1102
1103 2002-01-11  Tim Van Holder  <tim.van.holder@pandora.be>
1104
1105         * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
1106         canonical definition.
1107         * src/system.h: Use the canonical definition for PARAMS (avoids
1108         a conflict with the macro from lib/hash.h).
1109
1110 2002-01-11  Akim Demaille  <akim@epita.fr>
1111
1112         * configure.in: Use AC_FUNC_STRNLEN.
1113         Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
1114
1115 2002-01-09  Akim Demaille  <akim@epita.fr>
1116
1117         * src/files.c, src/files.h (output_infix): New.
1118         (tab_extension): Remove.
1119         (compute_base_names): Compute the former, drop the latter.
1120         * src/output.c (prepare): Insert the muscles `output-infix', and
1121         `output-suffix'.
1122         * src/parse-skel.y (string, string.1): New.
1123         (section.header): Use it.
1124         (section.yacc): Remove.
1125         (prefix): Remove too.
1126         * src/scan-skel.l: Adjust.
1127         * src/bison.simple, src/bison.hairy: Adjust.
1128
1129 2002-01-09  Akim Demaille  <akim@epita.fr>
1130
1131         * configure.in (WERROR_CFLAGS): Compute it.
1132         * src/Makefile.am (CFLAGS): Pass it.
1133         * tests/atlocal.in (CFLAGS): Idem.
1134         * src/files.c: Fix a few warnings.
1135         (get_extension_index): Remove, unused.
1136
1137 2002-01-08  Akim Demaille  <akim@epita.fr>
1138
1139         * src/getargs.c (AS_FILE_NAME): New.
1140         (getargs): Use it to convert DOSish file names.
1141         * src/files.c (base_name): Rename as full_base_name to avoid
1142         clashes with `base_name ()'.
1143         (filename_split): New.
1144         (compute_base_names): N-th rewrite, using filename_split.
1145
1146 2002-01-08  Akim Demaille  <akim@epita.fr>
1147
1148         * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
1149         New, stolen from the Fileutils 4.1.
1150         * lib/Makefile.am (libbison_a_SOURCES): Adjust.
1151         * configure.in: Check for the presence of memrchr, and of its
1152         prototype.
1153
1154 2002-01-07  Tim Van Holder  <tim.van.holder@pandora.be>
1155
1156         * lib/hash.h (__P): Added definition for this macro.
1157         * src/Makefile.am: Add parse-skel.c and scan-skel.c to
1158         BUILT_SOURCES, to ensure they are generated first.
1159         * src/parse-skel.y: Use YYERROR_VERBOSE instead of
1160         %error-verbose to allow bootstrapping with bison 1.30x.
1161
1162 2002-01-06  Akim Demaille  <akim@epita.fr>
1163
1164         * src/reader.c (parse_braces): Don't fetch the next char, the
1165         convention is to fetch on entry.
1166         * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
1167         'switch' without a following semicolon.
1168         * tests/regression.at (braces parsing): New.
1169
1170 2002-01-06  Akim Demaille  <akim@epita.fr>
1171
1172         Bison is dead wrong in its RR conflict reports.
1173
1174         * tests/torture.at (GNU Cim Grammar): New.
1175         * src/conflicts.c (count_rr_conflicts): Fix.
1176
1177 2002-01-06  Akim Demaille  <akim@epita.fr>
1178
1179         Creating package.m4 from configure.ac causes too many problems.
1180
1181         * tests/Makefile.am (package.m4): Create it by hand,
1182         AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
1183
1184 2002-01-06  Akim Demaille  <akim@epita.fr>
1185
1186         * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
1187         skeleton.h.
1188
1189 2002-01-04  Paul Eggert  <eggert@twinsun.com>
1190
1191         * doc/bison.texinfo (Debugging):
1192         Remove YYSTDERR; it's no longer defined or used.
1193         Also, s/cstdio.h/cstdio/.
1194
1195 2002-01-03  Akim Demaille  <akim@epita.fr>
1196
1197         * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
1198
1199 2002-01-03  Akim Demaille  <akim@epita.fr>
1200
1201         * src/parse-skel.y (process_skeleton): Don't bind the parser's
1202         tracing code to --trace, wait for a better --trace option, with
1203         args.
1204
1205 2002-01-03  Akim Demaille  <akim@epita.fr>
1206
1207         * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
1208         The ISO C++ standard is extremely clear about it: stderr is
1209         considered a macro, not a regular symbol (see table 94 `Header
1210         <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
1211         Therefore std:: does not apply to it.  It still does with fprintf.
1212         Also, s/cstdio.h/cstdio/.
1213
1214 2002-01-03  Akim Demaille  <akim@epita.fr>
1215
1216         * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
1217         for non system headers.
1218
1219 2002-01-02  Akim Demaille  <akim@epita.fr>
1220
1221         Equip the skeleton chain with location tracking, runtime trace,
1222         pure parser and scanner.
1223
1224         * src/parse-skel.y: Request a pure parser, locations, and prefix
1225         renaming.
1226         (%union): Having several members with the same type does not help
1227         type mismatches, simplify.
1228         (YYPRINT, yyprint): New.
1229         (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
1230         (skel_error): this.
1231         Handle locations.
1232         * src/scan-skel.l: Adjust to these changes.
1233         * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
1234         (LOCATION_PRINT, skel_control_t): New.
1235
1236 2001-12-30  Akim Demaille  <akim@epita.fr>
1237
1238         * src/parse-skel.y: Get rid of the shift/reduce conflict:
1239         replace `gb' with BLANKS.
1240         * src/scan-skel.l: Adjust.
1241
1242 2001-12-30  Akim Demaille  <akim@epita.fr>
1243
1244         * src/system.h: We don't need nor want bcopy.
1245         Throw away MS-DOS crap: we don't need getpid.
1246         * configure.in: We don't need strndup.  It was even causing
1247         problems: because Flex includes the headers *before* us,
1248         _GNU_SOURCE is not defined by config.h, and therefore strndup was
1249         not visible.
1250         * lib/xstrndup.c: New.
1251         * src/scan-skel.l: Use it.
1252         Be sure to initialize yylval.muscle member when scanning a MUSCLE.
1253         * src/parse-skel.y: Use %directives instead of #defines.
1254
1255 2001-12-30  Akim Demaille  <akim@epita.fr>
1256
1257         * src/skeleton.h: New.
1258         * src/output.c (output_parser, output_master_parser): Remove, dead
1259         code.
1260         * src/output.h (get_lines_number, actions_output, guards_output)
1261         (token_definitions_output): Prototype them.
1262         * src/parse-skel.y: Add the license notice.
1263         Include output.h and skeleton.h.
1264         (process_skeleton): Returns void, and takes a single parameter.
1265         * src/scan-skel.l: Add the license notice.
1266         Include skeleton.h.
1267         Don't use %option yylineno: it seems that then Flex imagines
1268         REJECT has been used, and therefore it won't reallocate its
1269         buffers (which makes no other sense to me than a bug).  It results
1270         in warnings for `unused: yy_flex_realloc'.
1271
1272 2001-12-30  Robert Anisko  <robert.anisko@epita.fr>
1273
1274         * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
1275         (MUSCLE_INSERT_PREFIX): ...to there.
1276         * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
1277         (MUSCLE_INSERT_PREFIX): Move from here...
1278
1279         * src/bison.hairy: Add a section directive.  Put braces around muscle
1280         names.  This parser skeleton is still broken, but Bison should not
1281         choke on a bad muscle 'syntax'.
1282         * src/bison.simple: Add a section directive.  Put braces around muscle
1283         names.
1284
1285         * src/files.h (strsuffix, stringappend): Add declarations.
1286         (tab_extension): Add declaration.
1287         (short_base_name): Add declaration.
1288
1289         * src/files.c (strsuffix, stringappend): No longer static.  These
1290         functions are used in the skeleton parser.
1291         (tab_extension): New.
1292         (compute_base_names): Use the computations done in this function
1293         to guess if the generated parsers should have '.tab' in their
1294         names.
1295         (short_base_name): No longer static.
1296
1297         * src/output.c (output_skeleton): New.
1298         (output): Disable call to output_master_parser, and give a try to
1299         a new skeleton handling system.
1300         (guards_output, actions_output): No longer static.
1301         (token_definitions_output, get_lines_number): No longer static.
1302
1303         * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
1304
1305         * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
1306         parse-skel.y.
1307
1308         * src/parse-skel.y: New file.
1309         * src/scan-skel.l: New file.
1310
1311 2001-12-29  Akim Demaille  <akim@epita.fr>
1312
1313         %name-prefix is broken.
1314
1315         * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
1316         Adjust all dependencies.
1317         * tests/headers.at (export YYLTYPE): Strengthen this test: use
1318         %name-prefix.
1319
1320         Renaming yylval but not yylloc is not consistent.  Now we do.
1321
1322         * src/bison.simple: Prefix yylloc if used.
1323         * doc/bison.texinfo (Decl Summary): Document that.
1324
1325 2001-12-29  Akim Demaille  <akim@epita.fr>
1326
1327         * doc/bison.texinfo: Promote `%long-directive' over
1328         `%long_directive'.
1329         Remove all references to fixed-output-files, yacc is enough.
1330
1331 2001-12-29  Akim Demaille  <akim@epita.fr>
1332
1333         * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
1334         user prologue.  These are defaults.
1335         * tests/actions.at (Mid-rule actions): Make sure the user can
1336         define YYDEBUG and YYERROR_VERBOSE.
1337
1338 2001-12-29  Akim Demaille  <akim@epita.fr>
1339
1340         * src/output.c (header_output): Don't forget to export YYLTYPE and
1341         yylloc.
1342         * tests/headers.at (export YYLTYPE): New, make sure it does.
1343         * tests/regression.at (%union and --defines, Invalid CPP headers):
1344         Move to...
1345         * tests/headers.at: here.
1346
1347 2001-12-29  Akim Demaille  <akim@epita.fr>
1348
1349         * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
1350
1351 2001-12-29  Akim Demaille  <akim@epita.fr>
1352
1353         * tests/actions.at (Mid-rule actions): Output on a single line
1354         instead of several.
1355
1356 2001-12-29  Akim Demaille  <akim@epita.fr>
1357
1358         * doc/bison.texinfo: Formatting changes.
1359
1360 2001-12-29  Akim Demaille  <akim@epita.fr>
1361
1362         Don't store the token defs in a muscle, just be ready to output it
1363         on command.  Now possible via `symbols'.  Fixes a memory leak.
1364
1365         * src/output.c (token_definitions_output): New.
1366         (output_parser, header_output): Use it.
1367         * src/reader.c (symbols_save): Remove.
1368
1369 2001-12-29  Akim Demaille  <akim@epita.fr>
1370
1371         * src/bison.simple: Do not provide a default for YYSTYPE and
1372         YYLTYPE before the user's prologue.  Otherwise it's hardly... a
1373         default.
1374
1375 2001-12-29  Akim Demaille  <akim@epita.fr>
1376
1377         Mid-rule actions are simply... ignored!
1378
1379         * src/reader.c (readgram): Be sure to attach mid-rule actions to
1380         the empty-rule associated to the dummy symbol, not to the host
1381         rule.
1382         * tests/actions.at (Mid-rule actions): New.
1383
1384 2001-12-29  Akim Demaille  <akim@epita.fr>
1385
1386         Memory leak.
1387
1388         * src/reader.c (reader): Free grammar.
1389
1390 2001-12-29  Akim Demaille  <akim@epita.fr>
1391
1392         Memory leak.
1393
1394         * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
1395         since it allocates it for each state, although only one is needed.
1396         (allocate_storage): Do it here.
1397
1398 2001-12-29  Akim Demaille  <akim@epita.fr>
1399
1400         * src/options.h, src/options.c (create_long_option_table): Rename
1401         as...
1402         (long_option_table_new): this, with a clearer prototype.
1403         (percent_table): Remove, unused,
1404         * src/getargs.c (getargs): Adjust.
1405
1406 2001-12-29  Akim Demaille  <akim@epita.fr>
1407
1408         * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
1409         * src/print.c, src/print_graph.c, src/state.h: Rename state_table
1410         as states.
1411
1412 2001-12-29  Akim Demaille  <akim@epita.fr>
1413
1414         * src/lalr.c (build_relations): Rename `states' as `states1'.
1415         Sorry, I don't understand exactly what it is, no better name...
1416
1417 2001-12-29  Akim Demaille  <akim@epita.fr>
1418
1419         * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
1420         * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
1421         * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
1422         as rules.
1423
1424 2001-12-29  Akim Demaille  <akim@epita.fr>
1425
1426         * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
1427         ago.
1428
1429 2001-12-29  Akim Demaille  <akim@epita.fr>
1430
1431         * src/reader.c, src/reader.h (user_toknums): Remove.
1432         Adjust all users to use symbols[i]->user_token_number.
1433
1434 2001-12-29  Akim Demaille  <akim@epita.fr>
1435
1436         * src/gram.c, src/gram.h (sprec, sassoc): Remove.
1437         Adjust all users to use symbols[i]->prec or ->assoc.
1438
1439 2001-12-29  Akim Demaille  <akim@epita.fr>
1440
1441         * src/reader.c, src/reader.h (tags): Remove.
1442         Adjust all users to use symbols[i]->tag.
1443
1444 2001-12-29  Akim Demaille  <akim@epita.fr>
1445
1446         * src/gram.h, src/gram.c (symbols): New, similar to state_table
1447         and rule_table.
1448         * src/reader.c (packsymbols): Fill this table.
1449         Drop sprec.
1450         * src/conflicts.c (resolve_sr_conflict): Adjust.
1451         * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
1452         single table.
1453         Use symbols[i]->tag instead of tags[i].
1454
1455 2001-12-29  Akim Demaille  <akim@epita.fr>
1456
1457         * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
1458         In addition, put a comment in there, to replace...
1459         * tests/regression.at (%union and C comments): Remove.
1460
1461 2001-12-29  Akim Demaille  <akim@epita.fr>
1462
1463         * tests/regression.at (Web2c Actions): Blindly move the actual
1464         output as expected output.  The contents *seem* right to me, but I
1465         can't pretend reading perfectly parser tables...  Nonetheless, all
1466         the other tests pass correctly, the table look OK, even though the
1467         presence of `$axiom' is to be noted: AFAICS it is useless (but
1468         harmless).
1469
1470 2001-12-29  Akim Demaille  <akim@epita.fr>
1471
1472         * src/reader.c (readgram): Don't add the rule 0 if there were no
1473         rules read.  In other words, add it _after_ having performed
1474         grammar sanity checks.
1475         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
1476
1477 2001-12-29  Akim Demaille  <akim@epita.fr>
1478
1479         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
1480         visible, and some states have now a different number.
1481
1482 2001-12-29  Akim Demaille  <akim@epita.fr>
1483
1484         * src/reader.c (readgram): Bind the initial rule's lineno to that
1485         of the first rule.
1486         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
1487         (Solved SR Conflicts): Adjust rule 0's line number.
1488
1489 2001-12-29  Akim Demaille  <akim@epita.fr>
1490
1491         Fix the `GAWK Grammar' failure.
1492
1493         * src/LR0.c (final_state): Initialize to -1 so that we do compute
1494         the reductions of the first state which was mistakenly confused
1495         with the final state because precisely final_state was initialized
1496         to 0.
1497         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
1498         now noticed by Bison.
1499         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
1500         have a reduction on $default.
1501
1502 2001-12-29  Akim Demaille  <akim@epita.fr>
1503
1504         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
1505         rule line numbers.
1506         * src/closure.c (print_closure): Likewise.
1507         * src/derives.c (print_derives): Likewise.
1508         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
1509         now.
1510
1511 2001-12-29  Akim Demaille  <akim@epita.fr>
1512
1513         * src/lalr.c (lookaheads_print): New.
1514         (lalr): Call it when --trace-flag.
1515         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
1516         are dumped.
1517
1518 2001-12-29  Akim Demaille  <akim@epita.fr>
1519
1520         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
1521         when walking through ritem, even via rule->rhs.
1522         * src/reduce.c (dump_grammar, useful_production, reduce_output)
1523         (useful_production, useless_nonterminals): Likewise.
1524         (reduce_grammar_tables): Likewise, plus update nritems.
1525         * src/nullable.c (set_nullable): Likewise.
1526         * src/lalr.c (build_relations): Likewise.
1527         * tests/sets.at (Nullable): Adjust.
1528         Fortunately, now, the $axiom is no longer nullable.
1529
1530 2001-12-29  Akim Demaille  <akim@epita.fr>
1531
1532         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
1533         the 0-sentinel.
1534         * src/gram.c (ritem_longest_rhs): Likewise.
1535         * src/reduce.c (nonterminals_reduce): Likewise.
1536         * src/print_graph.c (print_graph): Likewise.
1537         * src/output.c (output_rule_data): Likewise.
1538         * src/nullable.c (set_nullable):  Likewise.
1539
1540 2001-12-29  Akim Demaille  <akim@epita.fr>
1541
1542         * src/output.c: Comment changes.
1543
1544 2001-12-27  Paul Eggert  <eggert@twinsun.com>
1545
1546         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
1547         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
1548         Sparc, as they were causing more porting problems than the
1549         (minor) performance improvement was worth.
1550
1551         Also, catch up with 1.31's YYSTD.
1552
1553 2001-12-27  Akim Demaille  <akim@epita.fr>
1554
1555         * src/output.c (output_gram): Rely on nritems, not the
1556         0-sentinel.  See below.
1557         Use -1 as separator, not 0.
1558         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
1559         Rely on -1 as separator in yyrhs, instead of 0.
1560         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
1561         twice `Now at end of input', therefore there are two lines less to
1562         expect.
1563
1564 2001-12-27  Akim Demaille  <akim@epita.fr>
1565
1566         * tests/regression.at (Unresolved SR Conflicts):
1567         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
1568         below.
1569
1570 2001-12-27  Akim Demaille  <akim@epita.fr>
1571
1572         * src/LR0.c (new_state): Recognize the final state by the fact it
1573         is reached by eoftoken.
1574         (insert_start_shifting_state, insert_eof_shifting_state)
1575         (insert_accepting_state, augment_automaton): Remove, since now
1576         these states are automatically computed from the initial state.
1577         (generate_states): Adjust.
1578         * src/print.c: When reporting a rule number to the user, substract
1579         1, so that the axiom rule is rule 0, and the first user rule is 1.
1580         * src/reduce.c: Likewise.
1581         * src/print_graph.c (print_core): For the time being, just as for
1582         the report, depend upon --trace-flags to dump the full set of
1583         items.
1584         * src/reader.c (readgram): Once the grammar read, insert the rule
1585         0: `$axiom: START-SYMBOL $'.
1586         * tests/set.at: Adjust: rule 0 is now displayed, and since the
1587         number of the states has changed (the final state is no longer
1588         necessarily the last), catch up.
1589
1590 2001-12-27  Akim Demaille  <akim@epita.fr>
1591
1592         Try to make the use of the eoftoken valid.  Given that its value
1593         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
1594         is used instead of > 0 where appropriate, (ii), depend upon nritems
1595         instead of the 0-sentinel.
1596
1597         * src/gram.h, src/gram.c (nritems): New.
1598         Expected to be duplication of nitems, but for the time being...
1599         * src/reader.c (packgram): Assert nritems and nitems are equal.
1600         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
1601         * src/closure.c (print_closure, print_fderives): Likewise.
1602         * src/gram.c (ritem_print): Likewise.
1603         * src/print.c (print_core, print_grammar): Likewise.
1604         * src/print_graph.c: Likewise.
1605
1606 2001-12-27  Akim Demaille  <akim@epita.fr>
1607
1608         * src/main.c (main): If there are complains after grammar
1609         reductions, then output the report anyway if requested, then die.
1610         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
1611         * src/reader.c (eoftoken): New.
1612         (parse_token_decl): If the token being defined has value `0', it
1613         is the eoftoken.
1614         (packsymbols): No longer hack `tags' to insert `$' by hand.
1615         Be sure to preserve the value of the eoftoken.
1616         (reader): Make sure eoftoken is defined.
1617         Initialize nsyms to 0: now eoftoken is created just like the others.
1618         * src/print.c (print_grammar): Don't special case the eof token.
1619         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
1620         lie anyway, albeit pleasant.
1621         * tests/calc.at: Exercise error messages with eoftoken.
1622         Change the grammar so that empty input is invalid.
1623         Adjust expectations.
1624         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
1625
1626 2001-12-27  Akim Demaille  <akim@epita.fr>
1627
1628         * configure.in: Check the protos of strchr ans strspn.
1629         Replace strchr if needed.
1630         * src/system.h: Provide the protos of strchr, strspn and memchr if
1631         missing.
1632         * lib/strchr.c: New.
1633         * src/reader.c (symbols_save): Use strchr.
1634
1635 2001-12-27  Akim Demaille  <akim@epita.fr>
1636
1637         * src/print.c, src/print_graph.c (escape): New.
1638         Use it to quote the TAGS outputs.
1639         * src/print_graph.c (print_state): Now errors are in red, and
1640         reductions in green.
1641         Prefer high to wide: output the state number on a line of its own.
1642
1643 2001-12-27  Akim Demaille  <akim@epita.fr>
1644
1645         * src/state.h, src/state.c (reductions_new): New.
1646         * src/LR0.c (set_state_table): Let all the states have a
1647         `reductions', even if reduced to 0.
1648         (save_reductions): Adjust.
1649         * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
1650         * src/print.c (print_reductions, print_actions): Adjust.
1651         * src/output.c (action_row): Adjust.
1652
1653 2001-12-27  Akim Demaille  <akim@epita.fr>
1654
1655         * src/state.h, src/state.c (errs_new, errs_dup): New.
1656         * src/LR0.c (set_state_table): Let all the states have an errs,
1657         even if reduced to 0.
1658         * src/print.c (print_errs, print_reductions): Adjust.
1659         * src/output.c (output_actions, action_row): Adjust.
1660         * src/conflicts.c (resolve_sr_conflict): Adjust.
1661
1662 2001-12-27  Akim Demaille  <akim@epita.fr>
1663
1664         * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
1665
1666 2001-12-27  Akim Demaille  <akim@epita.fr>
1667
1668         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
1669         * src/print.c: here.
1670         (lookaheadset, shiftset): New, used as additional storage by
1671         print_reductions.
1672         (print_results): Adjust.
1673         (print_shifts, print_gotos, print_errs): New, extracted from...
1674         (print_actions): here.
1675         * src/print_graph.c (print_actions): Remove dead code.
1676
1677 2001-12-27  Akim Demaille  <akim@epita.fr>
1678
1679         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
1680         `$n' and `@n'.
1681
1682 2001-12-27  Akim Demaille  <akim@epita.fr>
1683
1684         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
1685         (build_relations): Adjust.
1686
1687 2001-12-27  Akim Demaille  <akim@epita.fr>
1688
1689         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
1690         duplication.
1691
1692 2001-12-27  Akim Demaille  <akim@epita.fr>
1693
1694         * src/reader.c (packgram): Catch nitems overflows.
1695
1696 2001-12-27  Akim Demaille  <akim@epita.fr>
1697
1698         * src/files.c, src/files.h (guard_obstack): Remove.
1699         * src/output.c (output): Adjust.
1700         * src/reader.c (parse_braces): New, factoring...
1701         (copy_action, copy_guard): these two which are renamed as...
1702         (parse_action, parse_guard): these.
1703         As a voluntary consequence, using braces around guards is now
1704         mandatory.
1705
1706 2001-12-27  Akim Demaille  <akim@epita.fr>
1707
1708         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
1709         * src/reader.c (symbol_list): `guard' and `guard_line' are new
1710         members.
1711         (symbol_list_new): Adjust.
1712         (copy_action): action_line is the first line, not the last.
1713         (copy_guard): Just as for actions, store the `action' only, not
1714         the switch/case/break flesh.
1715         Don't parse the user action that might follow the guard, let...
1716         (readgram): do it, i.e., now, there can be an action after a
1717         guard.
1718         In other words the guard is just explicitly optional.
1719         (packgram): Adjust.
1720         * src/output.c (guards_output): New.
1721         (output_parser): Call it when needed.
1722         (output): Also free the guard and attrs obstacks.
1723         * src/files.c, src/files.h (obstack_save): Remove.
1724         (output_files): Remove.
1725         As a result, if one needs the former `.act' file, using an
1726         appropriate skeleton which requires actions and guards is now
1727         required.
1728         * src/main.c (main): Adjust.
1729         * tests/semantic.at: New.
1730         * tests/regression.at: Use `input.y' as input file name.
1731         Avoid 8+3 problems by requiring input.c when the test needs the
1732         parser.
1733
1734 2001-12-27  Akim Demaille  <akim@epita.fr>
1735
1736         * src/reader.c (symbol_list_new): Be sure to initialize all the
1737         fields.
1738
1739 2001-12-27  Akim Demaille  <akim@epita.fr>
1740
1741         All the hacks using a final pseudo state are now useless.
1742
1743         * src/LR0.c (set_state_table): state_table holds exactly nstates.
1744         * src/lalr.c (nLA): New.
1745         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
1746         instead of lookaheadsp from the pseudo state (nstate + 1).
1747
1748 2001-12-27  Akim Demaille  <akim@epita.fr>
1749
1750         * src/output.c (action_row, token_actions): Use a state_t instead
1751         of a integer, and nlookaheads instead of the following state's
1752         lookaheadsp.
1753
1754 2001-12-27  Akim Demaille  <akim@epita.fr>
1755
1756         * src/conflicts.c (log_resolution, flush_shift)
1757         (resolve_sr_conflict, set_conflicts, solve_conflicts)
1758         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
1759         (conflicts_print, print_reductions): Use a state_t instead of an
1760         integer when referring to a state.
1761         As much as possible, depend upon nlookaheads, instead of the
1762         `lookaheadsp' member of the following state (since lookaheads of
1763         successive states are successive, the difference between state n + 1
1764         and n served as the number of lookaheads for state n).
1765         * src/lalr.c (add_lookback_edge): Likewise.
1766         * src/print.c (print_core, print_actions, print_state)
1767         (print_results): Likewise.
1768         * src/print_graph.c (print_core, print_actions, print_state)
1769         (print_graph): Likewise.
1770         * src/conflicts.h: Adjust.
1771
1772 2001-12-27  Akim Demaille  <akim@epita.fr>
1773
1774         * src/bison.hairy: Formatting/comment changes.
1775         ANSIfy.
1776         Remove `register' indications.
1777         Add plenty of `static'.
1778
1779 2001-12-27  Akim Demaille  <akim@epita.fr>
1780
1781         * src/output.c (prepare): Drop the muscle `ntbase' which
1782         duplicates ntokens.
1783         * src/bison.simple: Formatting/comment changes.
1784         Use YYNTOKENS only, which is documented, but not YYNTBASE, which

1788
1789         * src/output.c (output_table_data): Change the prototype to use
1790         `int' for array ranges: some invocations do pass an int, not a
1791         short.
1792         Reported by Wayne Green.

1796         Some actions of web2c.y are improperly triggered.
1797         Reported by Mike Castle.
1798
1799         * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
1800         * tests/regression.at (Web2c): Rename as...
1801         (Web2c Report): this.

1814         Some host fail on `assert (!"foo")', which expands to
1815         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
1816         Reported by Nelson Beebee.
1817
1818         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
1819         `#define it_succeeded 0' and `assert (it_succeeded)'.
1820
1821 2001-12-17  Marc Autret  <autret_m@epita.fr>
1822
1823         * src/bison.simple: Don't hard code the skeleton line and filename.
1824         * src/output.c (output_parser): Rename 'line' as 'output_line'.
1825         New line counter 'skeleton_line' (skeleton-line muscle).
1826
1827 2001-12-17  Paul Eggert  <eggert@twinsun.com>
1828
1829         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
1830         YYDEBUG must be defined to a nonzero value.
1831
1832         * src/bison.simple (yytname): Do not assume that the user defines
1833         YYDEBUG to a properly parenthesized expression.
1834
1835 2001-12-17  Akim Demaille  <akim@epita.fr>
1836
1837         * src/state.h (state_t): Rename lookaheads as lookaheadsp.
1838         nlookaheads is a new member.
1839         Adjust all users.
1840         * src/lalr.h (nlookaheads): Remove this orphan declaration.
1841         * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
1842         state.
1843
1844 2001-12-17  Akim Demaille  <akim@epita.fr>
1845
1846         * src/files.h, src/files.c (open_files, close_files): Remove.
1847         * src/main.c (main): Don't open/close files, nor invoke lex_free,
1848         let...
1849         * src/reader.c (reader): Do it.
1850
1851 2001-12-17  Akim Demaille  <akim@epita.fr>
1852
1853         * src/conflicts.c (print_reductions): Formatting changes.

1859         (resolve_sr_conflict): Adjust.
1860
1861 2001-12-17  Akim Demaille  <akim@epita.fr>
1862
1863         * src/output.c (output_obstack): Be static and rename as...
1864         (format_obstack): this, to avoid any confusion with files.c's
1865         output_obstack.
1866         * src/reader.h (muscle_obstack): Move to...
1867         * src/output.h: here, since it's defined in output.c.
1868
1869 2001-12-17  Akim Demaille  <akim@epita.fr>
1870
1871         * src/output.c (action_row, save_column, default_goto)
1872         (sort_actions, matching_state, pack_vector): Better variable
1873         locality.

1876

1878
1879 2001-12-17  Akim Demaille  <akim@epita.fr>
1880
1881         * src/files.c (output_files): Free the output_obstack.

1886
1887 2001-12-16  Marc Autret  <autret_m@epita.fr>
1888
1889         * src/output.c (actions_output): Fix. When we use %no-lines,
1890         there is one less line per action.
1891
1892 2001-12-16  Marc Autret  <autret_m@epita.fr>
1893
1894         * src/bison.simple: Remove a useless #line directive.
1895         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
1896         * src/output.c (get_lines_number): New.
1897         (output_parser): Adjust, now takes care about the lines of a
1898         output muscles.
1899         Fix line numbering.
1900         (actions_output): Computes the number of lines taken by actions.
1901         (output_master_parser): Insert new skeleton which is the name of
1902         the output parser file name.
1903
1904 2001-12-15  Marc Autret  <autret_m@epita.fr>
1905
1906         * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
1907
1908 2001-12-15  Marc Autret  <autret_m@epita.fr>
1909
1910         * src/output.c (output_gram): Keep track of the hairy one.
1911
1912 2001-12-15  Akim Demaille  <akim@epita.fr>
1913
1914         Make `make distcheck' work.
1915
1916         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
1917         system.h which uses libgettext.h.
1918
1919 2001-12-15  Akim Demaille  <akim@epita.fr>
1920
1921         * src/nullable.c (set_nullable): Useless rules must be skipped,
1922         otherwise, since we range over their symbols, we might look at a
1923         nonterminal which no longer ``exists'', i.e., it is not counted in
1924         `nvars', hence we overflow our arrays.
1925
1926 2001-12-15  Akim Demaille  <akim@epita.fr>
1927
1928         The header can also be produced directly, without any obstack!
1929         Yahoo!
1930
1931         * src/files.c, src/files.h (defines_obstack): Remove.
1932         (compute_header_macro): Global.
1933         (defines_obstack_save): Remove.
1934         * src/reader.c (parse_union_decl): No longer output to
1935         defines_obstack: its content can be found in the `stype' muscle
1936         anyway.
1937         (output_token_translations): Merge into...
1938         (symbols_output): this.
1939         Rename as...
1940         (symbols_save): this.
1941         (reader): Adjust.
1942         * src/output.c (header_output): New.
1943         (output): Call it.
1944
1945 2001-12-15  Akim Demaille  <akim@epita.fr>
1946
1947         * src/reader.c (parse_union_decl): Instead of handling two obstack
1948         simultaneously, use one to define the `stype' muscle, and use the
1949         value of the latter to fill defines_obstack.
1950         (copy_comment): Remove.
1951         (copy_comment2): Work for a single obstack.
1952         Rename as...
1953         (copy_comment): this.
1954
1955 2001-12-15  Akim Demaille  <akim@epita.fr>
1956
1957         * src/lex.c, src/lex.h (xgetc): No longer static.
1958         * src/reader.c (parse_union_decl): Revamp.
1959
1960 2001-12-15  Akim Demaille  <akim@epita.fr>
1961
1962         Still making progress in separating Bison into (i) input, (ii)
1963         process, (iii) output: now we can directly output the parser file
1964         without using table_obstack at all.
1965
1966         * src/files.c, src/files.h (table_obstack): Bye bye.
1967         (parser_file_name): New.
1968         * src/files.c (compute_output_file_names): Compute it.
1969         * src/output.c (actions_output, output_parser)
1970         (output_master_parser): To a file instead of an obstack.
1971
1972 2001-12-15  Akim Demaille  <akim@epita.fr>
1973
1974         Attach actions to rules, instead of pre-outputting them to
1975         actions_obstack.
1976
1977         * src/gram.h (rule_t): action and action_line are new members.
1978         * src/reader.c (symbol_list): Likewise.
1979         (copy_action): Save the actions within the rule.
1980         (packgram): Save them in rule_table.
1981         * src/output.c (actions_output): New.
1982         (output_parser): Use it on `%%actions'.
1983         (output_rule_data): Don't free rule_table.
1984         (output): Do it.
1985         (prepare): Don't save the `action' muscle.
1986         * src/bison.simple: s/%%action/%%actions/.
1987
1988 2001-12-15  Akim Demaille  <akim@epita.fr>
1989
1990         * src/reader.c (copy_action): When --yacc, don't append a `;'
1991         to the user action: let it fail if lacking.
1992         Suggested by Arnold Robbins and Tom Tromey.
1993
1994 2001-12-14  Akim Demaille  <akim@epita.fr>
1995
1996         * src/lex.c (literalchar): Simply return the char you decoded, non
1997         longer mess around with obstacks and int pointers.
1998         Adjust all callers.
1999
2000 2001-12-14  Akim Demaille  <akim@epita.fr>
2001
2002         * src/lex.c (literalchar): Don't escape the special characters,
2003         just decode them, and keep them as char (before, eol was output as
2004         the 2 char string `\n' etc.).
2005         * src/output.c (output_rule_data): Use quotearg to output the
2006         token strings.
2007
2008 2001-12-13  Paul Eggert  <eggert@twinsun.com>
2009
2010         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
2011         Do not infringe on the global user namespace when using C++.
2012         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
2013         All uses of `fprintf' and `stderr' changed.
2014
2015         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
2016
2017 2001-12-13  Akim Demaille  <akim@epita.fr>
2018
2019         The computation of nullable is broken: it doesn't handle empty
2020         RHS's properly.
2021
2022         * tests/torture.at (GNU AWK Grammar): New.
2023         * tests/sets.at (Nullable): New.
2024         * src/nullable.c (set_nullable): Instead of blindly looping over
2025         `ritems', loop over the rules, and then over their rhs's.
2026
2027         Work around Autotest bugs.
2028
2029         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
2030         frame, because Autotest understand lines starting with a `+' as
2031         traces from the shell.  Then, they are not processed properly.
2032         Admittedly an Autotest bug, but we don't have time to wait for
2033         Autotest to catch up.
2034         * tests/regression.at (Broken Closure): Adjust to the new table
2035         frames.
2036         Move to...
2037         * tests/sets.at: here.
2038
2039 2001-12-13  Akim Demaille  <akim@epita.fr>
2040
2041         * src/closure.c (closure): Use nrules instead of playing tricks
2042         with BITS_PER_WORD.
2043
2044 2001-12-13  Akim Demaille  <akim@epita.fr>
2045
2046         * src/print.c (print_actions): Output the handling of `$' as the
2047         traces do: shifting the token EOF.  Before EOF was treated as a
2048         nonterminal.
2049         * tests/regression.at: Adjust some tests.
2050         * src/print_graph.c (print_core): Complete the set of items via
2051         closure.  The next-to-final and final states are still unsatisfying,
2052         but that's to be addressed elsewhere.
2053         No longer output the rule numbers, but do output the state number.
2054         A single loop for the shifts + gotos is enough, but picked a
2055         distinct color for each.
2056         (print_graph): Initialize and finalize closure.
2057
2058 2001-12-13  Akim Demaille  <akim@epita.fr>
2059
2060         * src/reader.c (readgram): Remove dead code, an strip useless
2061         braces.
2062         (get_type): Remove, unused.
2063
2064 2001-12-12  Akim Demaille  <akim@epita.fr>
2065
2066         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
2067         on that of lib/error.c.
2068
2069 2001-12-12  Akim Demaille  <akim@epita.fr>
2070
2071         Some hosts don't like `/' in includes.
2072
2073         * src/system.h: Include libgettext.h without qualifying the path.
2074         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
2075         $(top_srcdir).
2076
2077 2001-12-11  Marc Autret  <autret_m@epita.fr>
2078
2079         * src/output.c (output_parser): Remove useless muscle.
2080
2081 2001-12-11  Marc Autret  <autret_m@epita.fr>
2082
2083         * src/bison.simple: Remove #line just before %%epilogue. It
2084         is now handled in ...
2085         * src/reader.c (read_additionnal_code): Add the output of a
2086         #line for the epilogue.
2087
2088 2001-12-10  Marc Autret  <autret_m@epita.fr>
2089
2090         * src/reader.c (copy_definition): Re-use CPP-outed code which
2091         replace precedent remove.
2092         * src/bison.simple: Remove #line before %%prologue because
2093         %%input-line is wrong at this time.
2094
2095 2001-12-10  Marc Autret  <autret_m@epita.fr>
2096
2097         * src/reader.c (symbols_output): Clean up.
2098         * src/output.c (output_gram, output): Clean up.
2099
2100 2001-12-10  Akim Demaille  <akim@epita.fr>
2101
2102         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
2103         * src/LR0.c (set_state_table): here.
2104         * src/lalr.c (lalr): Call it.
2105
2106 2001-12-10  Akim Demaille  <akim@epita.fr>
2107
2108         * src/state.h (shifts): Remove the `number' member: shifts are
2109         attached to state, hence no longer need to be labelled with a
2110         state number.
2111
2112 2001-12-10  Akim Demaille  <akim@epita.fr>
2113
2114         Now that states have a complete set of members, the linked list of
2115         shifts is useless: just fill directly the state's shifts member.
2116
2117         * src/state.h (shifts): Remove the `next' member.
2118         * src/LR0.c (first_state, last_state): Remove.
2119         Adjust the callers.
2120         (augment_automaton): Don't look for the shifts that must be added
2121         a shift on EOF: it is those of the state we looked for!  But now,
2122         since shifts are attached, it is no longer needed to looking
2123         merely by its id: its number.
2124
2125 2001-12-10  Akim Demaille  <akim@epita.fr>
2126
2127         * src/LR0.c (augment_automaton): Better variable locality.
2128         Remove an impossible branch: if there is a state corresponding to
2129         the start symbol being shifted, then there is shift for the start
2130         symbol from the initial state.
2131
2132 2001-12-10  Akim Demaille  <akim@epita.fr>
2133
2134         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
2135         only when appropriate: when insert_start_shifting_state' is not
2136         invoked.
2137         * tests/regression.at (Rule Line Numbers): Adjust.
2138
2139 2001-12-10  Akim Demaille  <akim@epita.fr>
2140
2141         * src/LR0.c (augment_automaton): Now that all states have shifts,
2142         merge the two cases addition shifts to the initial state.
2143
2144 2001-12-10  Akim Demaille  <akim@epita.fr>
2145
2146         * src/lalr.c (set_state_table): Move to...
2147         * src/LR0.c: here.
2148         * src/lalr.c (lalr): Don't call it...
2149         * src/LR0.c (generate_states): do it.
2150         * src/LR0.h (first_state): Remove, only the table is used.
2151
2152 2001-12-10  Akim Demaille  <akim@epita.fr>
2153
2154         * src/LR0.h (first_shift, first_reduction): Remove.
2155         * src/lalr.c: Don't use first_shift: find shifts through the
2156         states.
2157
2158 2001-12-10  Akim Demaille  <akim@epita.fr>
2159
2160         * src/LR0.c: Attach shifts to states as soon as they are
2161         computed.
2162         * src/lalr.c (set_state_table): Instead of assigning shifts to
2163         state, just assert that the mapping was properly done.
2164
2165 2001-12-10  Akim Demaille  <akim@epita.fr>
2166
2167         * src/LR0.c (insert_start_shift): Rename as...
2168         (insert_start_shifting_state): this.
2169         (insert_eof_shifting_state, insert_accepting_state): New.
2170         (augment_automaton): Adjust.
2171         Better locality of the variables.
2172         When looking if the start_symbol is shifted from the initial
2173         state, using `while (... symbol != start_symbol ...)' sounds
2174         better than `while (... symbol < start_symbol ...)': If fail
2175         to see how the order between symbols could be relevant!
2176
2177 2001-12-10  Akim Demaille  <akim@epita.fr>
2178
2179         * src/getargs.h: Don't declare `spec_name_prefix' and
2180         `spec_file_prefix', declared by src/files.h.
2181         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
2182         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
2183         * src/output.c (prepare): Adjust.
2184         * src/reader.c (symbols_output): Likewise.
2185         * src/vmsgetargs.c: Vaguely adjust, but who cares?
2186
2187 2001-12-10  Akim Demaille  <akim@epita.fr>
2188
2189         * src/muscle_tab.c (muscle_init): NULL is a better default than
2190         `"0"'.
2191
2192 2001-12-10  Akim Demaille  <akim@epita.fr>
2193
2194         * src/reader.c (reader): Calling symbols_output once is enough.
2195
2196 2001-12-10  Akim Demaille  <akim@epita.fr>
2197
2198         Now that states have a complete set of members, the linked list of
2199         reductions is useless: just fill directly the state's reductions
2200         member.
2201
2202         * src/state.h (struct reductions): Remove member `number' and
2203         `next'.
2204         * src/LR0.c (first_reduction, last_reduction): Remove.
2205         (save_reductions): Don't link the new reductions, store them in
2206         this_state.
2207         * src/lalr.c (set_state_table): No need to attach reductions to
2208         states, it's already done.
2209         * src/output.c (output_actions): No longer free the shifts, then
2210         the reductions, then the states: free all the states and their
2211         members.
2212
2213 2001-12-10  Akim Demaille  <akim@epita.fr>
2214
2215         * src/options.c (OPTN, DRTV, BOTH): New.
2216         (option_table): Use them.
2217
2218         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
2219         the job of system.h.
2220         * src/options.c: Don't include stdio.h and xalloc.h for the same
2221         reasons.
2222
2223 2001-12-10  Akim Demaille  <akim@epita.fr>
2224
2225         * src/output.c (output, prepare): Make sure the values of the
2226         muscles `action' and `prologue' are 0-terminated.
2227
2228 2001-12-10  Akim Demaille  <akim@epita.fr>
2229
2230         Clean up GCC warnings.
2231
2232         * src/reader.c (copy_action): `buf' is not used.
2233         (parse_skel_decl): Be static.
2234         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
2235         * src/options.h (create_long_option_table): Have a real prototype.
2236         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
2237         (hash_delete_at): Return const void *.
2238         Adjust casts to preserve the const.
2239
2240 2001-12-10  Akim Demaille  <akim@epita.fr>
2241
2242         * configure.in: Require 2.52g.
2243         M4 is not needed, but AUTOM4TE is.
2244         * m4/m4.m4: Remove.
2245         * tests/Makefile.am: Adjust.
2246
2247 2001-12-10  Akim Demaille  <akim@epita.fr>
2248
2249         One structure for states is enough, even though theoretically
2250         there are LR(0) states and LALR(1) states.
2251
2252         * src/lalr.h (state_t): Remove.
2253         (state_table): Be state_t **, not state_t *.
2254         * src/state.h (core, CORE_ALLOC): Rename as...
2255         (state_t, STATE_ALLOC): this.
2256         Add the LALR(1) members: shifts, reductions, errs.
2257         * src/LR0.c (state_table): Rename as...
2258         (state_hash): this, to avoid name clashes with the global
2259         `state_table'.
2260         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
2261         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.

2263 2001-12-10  Akim Demaille  <akim@epita.fr>
2264
2265         Bison dumps core on bash.y.
2266         Reported by Pascal Bart.
2267
2268         * src/warshall.c (bitmatrix_print): New.
2269         (TC): Use it.
2270         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
2271         j must be the outer loop.
2272         * tests/regression.at (Broken Closure): New.
2273
2274 2001-12-05  Akim Demaille  <akim@epita.fr>
2275
2276         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
2277         its argument.
2278         Reported by Peter Hámorský.
2279
2280 2001-12-05  Akim Demaille  <akim@epita.fr>
2281
2282         * src/conflicts.c (err_table): Remove.
2283         (resolve_sr_conflict): Adjust.
2284         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
2285         Rename as...
2286         (state_t.reductions, state_t.shifts): this.
2287
2288 2001-12-05  Akim Demaille  <akim@epita.fr>
2289
2290         * src/reduce.c (reduce_grammar_tables): No longer disable the
2291         removal of useless rules via CPP but via `if (0)', so that the
2292         compiler still check the code is valid.
2293         For instance, it should have noticed `rline' no longer exists: use
2294         the `line' member of rule_t.
2295         * src/gram.c (dummy, rline): Remove, unused.
2296
2297 2001-12-05  Akim Demaille  <akim@epita.fr>
2298
2299         * src/output.c (pack_vector): Use assert, not berror.
2300         * src/main.c (berror): Remove, unused.
2301
2302 2001-12-05  Akim Demaille  <akim@epita.fr>
2303
2304         New experimental feature: if --verbose --trace output all the
2305         items of a state, not only its kernel.
2306
2307         * src/print.c (print_core): If `trace_flag', then invoke closure
2308         before outputting the items of the state (print_core is no longer
2309         a correct name them).
2310         (print_results): Invoke new_closure/free_closure if needed.
2311
2312 2001-12-05  Akim Demaille  <akim@epita.fr>
2313
2314         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
2315         * src/closure.c, src/closure.h (itemsetsize): Rename as...
2316         (nitemset): for consistency with the rest of the project.
2317
2318 2001-12-05  Akim Demaille  <akim@epita.fr>
2319
2320         * src/closure.c (print_closure): Improve.
2321         (closure): Use it for printing input and output.
2322
2323 2001-12-05  Akim Demaille  <akim@epita.fr>
2324
2325         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
2326         indexed by nonterminals.
2327
2328 2001-12-05  Akim Demaille  <akim@epita.fr>
2329
2330         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
2331         what it was!).
2332         * src/warshall.h: Remove accidental duplication of the content.
2333
2334 2001-12-05  Akim Demaille  <akim@epita.fr>
2335
2336         * src/closure.c (set_fderives): De-obfuscate.

2346 2001-12-05  Akim Demaille  <akim@epita.fr>
2347
2348         * src/output.c (action_row): De-obfuscate
2349         using the good o' techniques: arrays not pointers, variable
2350         locality, BITISSET, RESETBIT etc.
2351
2352 2001-12-05  Akim Demaille  <akim@epita.fr>
2353
2354         Pessimize the code to simplify it: from now on, all the states
2355         have a valid SHIFTS, which NSHIFTS is possibly 0.
2356
2357         * src/LR0.c (shifts_new): Be global and move to..
2358         * src/state.c, src/state.h: here.
2359         * src/conflicts, src/lalr.c, src/output.c, src/print.c,

2361
2362 2001-12-05  Akim Demaille  <akim@epita.fr>
2363
2364         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
2365         * src/conflicts.c: Use it.
2366         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
2367         incorrectly ``simplified''.
2368
2369 2001-12-05  Akim Demaille  <akim@epita.fr>
2370
2371         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
2372         using the good o' techniques: arrays not pointers, variable
2373         locality, BITISSET, RESETBIT etc.
2374
2375 2001-12-05  Akim Demaille  <akim@epita.fr>
2376
2377         * src/state.h (SHIFT_SYMBOL): New.

2379
2380 2001-12-05  Akim Demaille  <akim@epita.fr>
2381
2382         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
2383         (print_reductions): De-obfuscate using the good o' techniques:
2384         arrays not pointers, variable locality, BITISSET.
2385
2386 2001-12-05  Akim Demaille  <akim@epita.fr>
2387
2388         * src/conflicts.c (print_reductions): Arrays, not pointers.

2411
2412 2001-12-05  Akim Demaille  <akim@epita.fr>
2413
2414         * src/LR0.c (augment_automaton): Formatting changes.
2415         Better variable locality.
2416
2417 2001-12-05  Akim Demaille  <akim@epita.fr>
2418
2419         * src/lalr.c (matrix_print): New.
2420         (transpose): Use it.
2421         Use arrays instead of pointers.
2422
2423 2001-12-05  Akim Demaille  <akim@epita.fr>
2424
2425         * src/lalr.c (maxrhs): Move to...
2426         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
2427         * src/lalr.c (build_relations): Adjust.
2428
2429 2001-12-05  Akim Demaille  <akim@epita.fr>
2430
2431         * src/lalr.c (transpose): Free the memory allocated to the
2432         argument, as it is replaced by the results by the unique caller.
2433         (build_relations): Merely invoke transpose: it handles the memory
2434         deallocation.
2435         Improve variable locality.
2436         Avoid variables used as mere abbreviations.
2437         (compute_lookaheads): Use arrays instead of pointers.
2438
2439 2001-12-05  Akim Demaille  <akim@epita.fr>
2440
2441         * src/lalr.c (initialize_F): Improve variable locality.

2443
2444 2001-12-05  Akim Demaille  <akim@epita.fr>
2445
2446         * src/derives.c (print_derives): Display the ruleno.
2447         * src/lalr.c (initialize_F, transpose): Better variable locality
2448         to improve readability.
2449         Avoid variables used as mere abbreviations.
2450
2451 2001-12-05  Akim Demaille  <akim@epita.fr>
2452
2453         * src/lalr.c (traverse): Use arrays instead of pointers.
2454
2455 2001-12-05  Akim Demaille  <akim@epita.fr>
2456
2457         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
2458         the handling of squeue.
2459         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
2460
2461 2001-12-05  Akim Demaille  <akim@epita.fr>
2462
2463         Because useless nonterminals are now kept alive (instead of being
2464         `destroyed'), we now sometimes examine them, and store information
2465         related to them.  Hence we need to know their number, and adjust
2466         memory allocations.
2467
2468         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
2469         static.
2470         * src/LR0.c (allocate_itemsets): The memory allocated to
2471         `symbol_count' was used for two different purpose: once to count
2472         the number of occurrences of each symbol, and later reassigned to
2473         `shift_symbol', containing the symbol that can be shifted from a
2474         given state.
2475         Deobfuscate, i.e., allocate, use and free `symbol_count' here
2476         only, and...
2477         (new_itemsets): Allocate `shift_symbol' here.
2478         (allocate_itemsets): symbol_count includes useless nonterminals.
2479         Make room for them.
2480         (free_storage): Use `free', not `XFREE', for pointers that cannot
2481         be null.
2482
2483 2001-12-05  Akim Demaille  <akim@epita.fr>
2484
2485         * src/nullable.c (set_nullable): Deobfuscate the handling of
2486         ritem.
2487         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
2488
2489 2001-12-05  Akim Demaille  <akim@epita.fr>
2490
2491         * src/gram.c, src/gram.h (ritem_print): New.
2492         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
2493         (This useless function was defined only to work around VMS linkers
2494         that can't handle compilation units with variables only).
2495         * src/reduce.c (dump_grammar): Use it to trace the construction of
2496         ritem.
2497
2498 2001-12-04  Paul Eggert  <eggert@twinsun.com>
2499
2500         * src/bison.simple (union yyalloc): Change member names
2501         to be the same as the stack names.
2502         (yyparse): yyptr is now union yyalloc *, not char *.
2503         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
2504         and may generate better code on some machines.
2505         (yystpcpy): Use prototype if __STDC__ is defined, not just
2506         if __cplusplus is defined.
2507
2508 2001-11-30  Akim Demaille  <akim@epita.fr>
2509
2510         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
2511         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
2512         Gettext doesn't compile cleanly, and dies with -Werror.
2513         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
2514         Include WARNING_CFLAGS here.
2515         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
2516         before being defined.

2524         (quotearg_n_options): Abort if N is negative.
2525         Avoid overflow check on hosts where size_t is 64 bits and int
2526         is 32 bits, as overflow is impossible there.
2527         Fix off-by-one typo that caused unnecessary reallocation.
2528
2529 2001-11-29  Paul Eggert  <eggert@twinsun.com>
2530
2531         Name space cleanup in generated parser.
2532
2533         * doc/bison.texinfo (Bison Parser): Discuss system headers
2534         and their effect on the user name space.
2535
2536         * src/bison.simple:
2537         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
2538         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
2539         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
2540
2541         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
2542         on user names when possible.
2543
2544         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
2545         Simplify test for whather <alloca.h> exists.
2546
2547         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
2548
2549         (<stdio.h>): Include if YYDEBUG.
2550

2558
2559         (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
2560         All uses changed.
2561
2562         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
2563         instead of relying on string.h functions.  Use YYSTACK_ALLOC
2564         and YYSTACK_FREE instead of malloc and free.
2565
2566 2001-11-30  Akim Demaille  <akim@epita.fr>
2567
2568         * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions

2577
2578         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty

2580
2581 2001-11-30  Akim Demaille  <akim@epita.fr>
2582
2583         Instead of mapping the LHS of unused rules to -1, keep the LHS
2584         valid, but flag the rules as invalid.
2585
2586         * src/gram.h (rule_t): `useful' is a new member.
2587         * src/print.c (print_grammar): Adjust.

2601
2602         * src/reduce.c (nonterminals_reduce): Instead of throwing away
2603         useless nonterminals, move them at the end of the symbol arrays.

2605         * tests/reduce.at (Useless Nonterminals): Adjust.
2606

2610         (nonterminals_reduce): New, extracted from...
2611         (reduce_grammar_tables): here.
2612         (reduce_grammar): Call nonterminals_reduce.

2619         New macros.
2620         (union yyalloc): New type.
2621         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
2622         an arbitrary restriction on hosts where size_t is wider than int.
2623
2624         (yyparse): Don't dump core if alloca or malloc fails; instead, report
2625         a parser stack overflow.  Allocate just one block of memory for all
2626         three stacks, instead of allocating three blocks; this typically is
2627         faster and reduces fragmentation.
2628
2629         Do not limit the number of items in the stack to a value that fits
2630         in 'int', as this is an arbitrary limit on hosts with 64-bit
2631         size_t and 32-bit int.
2632
2633 2001-11-29  Marc Autret  <autret_m@epita.fr>

2684         keep ruleno only.
2685
2686 2001-11-28  Akim Demaille  <akim@epita.fr>
2687
2688         * src/closure.c (closure): Instead of looping over word in array
2689         then bits in words, loop over bits in array.
2690
2691 2001-11-28  Akim Demaille  <akim@epita.fr>
2692
2693         * src/closure.c (closure): No longer optimize the special case
2694         where all the bits of `ruleset[r]' are set to 0, to make the code
2695         clearer.
2696

2698

3059         * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
3060         now the tests are run in private dirs, therefore AC_CLEANUP and

3088         arg_offset.
3089         arg is const.

4010
4011         * src/bison.simple (yyparse): Don't take the address of an

4021         completely wrong.

4060         bound to true.
4061         (read_declarations): Add case for macro definition.
4062         (copy_identifier): New.
4063         (parse_macro_decl): Read macro identifiers using copy_identifier

4098         with something new. Skeletons are now processed character by character
4099         rather than line by line, and Bison looks for '%%' macros. This is the
4100         first step in making Bison's output process (a lot) more flexible.
4101         (output_parser): Use the macro table.

4429
4430         * src/reader.c (gensym): `gensym_count' is your own.
4431         Use a static buf to create the symbol name, as token_buffer is no

4435
4436         * src/conflicts.c (conflict_report): Be sure not to append to res
4437         between two calls, which could happen if both first sprintf were

4443         New, from fileutils 4.0.37.
4444         * configure.in: Require Autoconf 2.49c.  I took some time before
4445         making this decision.  This is the only way out for portability
4446         issues in Bison, it would mean way too much duplicate effort to
4447         import in Bison features implemented in 2.49c since 2.13.
4448         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

4459
4460         * src/lex.c (token_obstack): New.
4461         (init_lex): Initialize it.  No longer call...

4466
4467         * src/lex.h: Rename all the tokens:
4468         s/\bENDFILE\b/tok_eof/g;
4469         s/\bIDENTIFIER\b/tok_identifier/g;
4470         etc.
4471         Let them be enums, not #define, to ease debugging.
4472         Adjust all the code.
4473
4474 2001-01-18  Akim Demaille  <akim@epita.fr>
4475
4476         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.

4478
4479 2001-01-18  Akim Demaille  <akim@epita.fr>
4480
4481         Since we now use obstacks, more % directives can be enabled.
4482
4483         * src/lex.c (percent_table): Also accept `%yacc',
4484         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
4485         `%debug'.
4486         Handle the actions for `%semantic_parser' and `%pure_parser' here,
4487         instead of returning a token.
4488         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
4489         * src/reader.c (read_declarations): Adjust.
4490         * src/files.c (open_files): Don't call `compute_base_names', don't
4491         compute `attrsfile' since they depend upon data which might be
4492         *in* the input file now.
4493         (output_files): Do it here.
4494         * src/output.c (output_headers): Document the fact that this patch
4495         introduces a guaranteed SEGV for semantic parsers.
4496         * doc/bison.texinfo: Document them.

4520         FILE * parameters.
4521
4522 2000-12-20  Akim Demaille  <akim@epita.fr>
4523
4524         * src/files.c (open_files): Actually the `.output' file is based
4525         on the short_base_name, not base_name.
4526         * tests/suite.at (Checking output file names): Adjust.
4527
4528 2000-12-20  Akim Demaille  <akim@epita.fr>
4529
4530         * src/bison.s1: Remove, we now use directly...

4554         (stringappend): Be just like strcat but allocate.
4555         (base_names): Eve out from open_files.
4556         Try to simplify the rather hairy computation of base_name and
4557         short_base_name.
4558         (open_files): Use it.
4559         * tests/suite.at (Checking output file names): New test.

4569
4570 2000-12-19  Akim Demaille  <akim@epita.fr>
4571

4577 2000-12-19  Akim Demaille  <akim@epita.fr>
4578
4579         Let the handling of the skeleton files be local to the procedures

4632         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
4633         prevents type checking.
4634         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
4635         cast the value to (void *): assigning a `foo *' to a `void *'
4636         variable is valid.
4637         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
4638         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to
4639         append characters.

4654
4655         * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New
4656         macros.

4673
4674 2000-11-07  Akim Demaille  <akim@epita.fr>
4675
4676         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
4677         Merge in a single CPP if/else.

4686         `address' for consistency.  Qualify it `const'.

4688         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
4689         `const' their input argument (`data' or `address').

4698 2000-11-03  Akim Demaille  <akim@epita.fr>

4700         For some reason, this was not applied.
4701
4702         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

4718         * src/main.c (main): Don't use `atexit' to register `done', since
4719         it no longer has to remove tmp files, just call `output_files'
4720         when there are no errors.

4823 2000-10-04  Akim Demaille  <akim@epita.fr>
4824
4825         When a literal string is used to define two different tokens,
4826         `bison -v' segfaults.
4827         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
4828
4829         * tests/regression.m4: New file.
4830         Include the core of the sample provided by Piotr Gackiewicz.
4831         * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
4832         properly.
4833
4834 2000-10-04  Akim Demaille  <akim@epita.fr>
4835
4836         * src/reader.c (parse_expect_decl): Keep `count' within the size
4837         of `buffer'.
4838         From Neil Booth.
4839
4840 2000-10-02  Paul Eggert  <eggert@twinsun.com>
4841
4842         * bison.s1 (yyparse): Assign the default value
4843         unconditionally, to avoid a GCC warning and make the parser a
4844         tad smaller.
4845
4846 2000-10-02  Akim Demaille  <akim@epita.fr>
4847
4848         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
4849         options.
4850
4851 2000-10-02  Akim Demaille  <akim@epita.fr>
4852
4853         * src/derives.c, src/print.c, src/reduce.c: To ease the
4854         translation, move some `\n' out of the translated strings.
4855
4856 2000-10-02  Akim Demaille  <akim@epita.fr>
4857
4858         The location tracking mechanism is precious for parse error
4859         messages.  Nevertheless, it is enabled only when `@n' is used in
4860         the grammar, which is a different issue (you can use it in error
4861         message, but not in the grammar per se).  Therefore, there should
4862         be another means to enable it.
4863
4864         * src/getargs.c (getargs): Support `--locations'.
4865         (usage): Report it.
4866         * src/getargs.h (locationsflag): Export it.
4867         * src/lex.c (percent_table): Support `%locations'.
4868         * src/reader.c (yylsp_needed): Remove this variable, now replaced
4869         with `locationsflag'.
4870         * doc/bison.texinfo: Document `--locations' and `%locations'.
4871         Sort the options.
4872         * tests/calc.m4: Test it.
4873
4874         For regularity of the names, replace each
4875         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
4876         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
4877         In addition replace each `flag' with `_flag'.
4878
4879 2000-10-02  Akim Demaille  <akim@epita.fr>
4880
4881         Also test parse error messages, including with YYERROR_VERBOSE.
4882
4883         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
4884         associative).
4885         Use it to check the computations.
4886         Use it to check `nonassoc' is honored.
4887         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
4888         `--yyerror-verbose'.
4889         (_AT_CHECK_CALC): Adjust to this option.
4890         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
4891
4892 2000-10-02  Akim Demaille  <akim@epita.fr>
4893
4894         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
4895         the latter demonstrates a flaw in the handling of non debugging
4896         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
4897         was used in order to simplify:
4898
4899         #if YYDEBUG
4900         if (yydebug)
4901         {
4902         ...
4903         }
4904         #endif
4905
4906         into
4907
4908         if (yydebug)
4909         {
4910         ...
4911         }
4912
4913         unfortunately this leads to a CPP conflict when
4914         `--name-prefix=foo' is used since it produces `#define yydebug
4915         foodebug'.
4916
4917         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
4918         (YYDPRINTF): New macro.
4919         Spread its use.
4920         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
4921         the bison options.
4922         Also test `--verbose', `--defines' and `--name-prefix'.
4923
4924 2000-10-02  Akim Demaille  <akim@epita.fr>
4925
4926         Improve the readability of the produced parsers.
4927
4928         * src/bison.s1: Formatting changes.
4929         Improve the comment related to the `$' mark.
4930         (yydefault): Don't fall through to `yyresume': `goto' there.
4931         * src/output.c (output_parser): When the `$' is met, skip the end
4932         of its line.
4933         New variable, `number_of_dollar_signs', to check there's exactly
4934         one `$' in the parser skeleton.
4935
4936 2000-10-02  Akim Demaille  <akim@epita.fr>
4937
4938         * lib/xstrdup.c: New file, from the fileutils.
4939         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
4940         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
4941         instead of strlen + xmalloc + strcpy.
4942         * src/symtab.c (copys): Remove, use xstrdup instead.
4943
4944 2000-10-02  Akim Demaille  <akim@epita.fr>
4945
4946         * src/gram.h (associativity): New enum type which replaces the
4947         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
4948         `right_assoc', `left_assoc' and `non_assoc'.
4949         Adjust all dependencies.
4950         * src/reader.c: Formatting changes.
4951         (LTYPESTR): Don't define it, use it as a literal in
4952         `reader_output_yylsp'.
4953         * src/symtab.h (symbol_class): New enum type which replaces the
4954         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
4955         `sunknown', `stoken and `snterm'.
4956
4957 2000-10-02  Akim Demaille  <akim@epita.fr>
4958
4959         * src/getargs.c (fixed_outfiles): Rename as...
4960         (yaccflag): for consistency and accuracy.
4961         Adjust dependencies.
4962
4963 2000-10-02  Akim Demaille  <akim@epita.fr>
4964
4965         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
4966         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
4967         difficult and introduced a lot of core dump.  It turns out that
4968         Bison used an implementation of `xmalloc' based on `calloc', and
4969         at various places it does depend upon the initialization to 0.  I
4970         have not tried to isolate the pertinent places, and all the former
4971         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
4972         someone should address this issue.
4973
4974         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
4975         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
4976         files.
4977         Adjust dependencies.
4978         * src/warshall.h: New file.
4979         Propagate.
4980
4981 2000-10-02  Akim Demaille  <akim@epita.fr>
4982
4983         Various anti-`extern in *.c' changes.
4984
4985         * src/system.h: Include `assert.h'.
4986
4987 2000-10-02  Akim Demaille  <akim@epita.fr>
4988
4989         * src/state.h (nstates, final_state, first_state, first_shift)

5070         YYDEFACT, that makes it possible for this function to use
5071         output_short_table.
5072
5073 2000-10-02  Akim Demaille  <akim@epita.fr>
5074
5075         `user_toknums' is output as a `short[]' in `output.c', while it is
5076         defined as a `int[]' in `reader.c'.  For consistency with the
5077         other output tables, `user_toknums' is now defined as a table of

5079
5080         * src/reader.c (user_toknums): Be a short table instead of an int

5121         * src/system.h: Define PARAMS.
5122         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the

5124         definitions in config.h.

5313         `cplus_comment'.
5314         (copy_comment, copy_string): Moved, to be visible from
5315         copy_definition.

5341
5342         Change the handling of @s so that they behave exactly like $s.
5343         There is now a pseudo variable @$ (readble and writable), location
5344         of the lhs of the rule (by default ranging from the location of
5345         the first symbol of the rhs, to the location of the last symbol,
5346         or, if the rhs is empty, YYLLOC).

5353         same way you stack YYVAL.
5354         * src/reader.c (read_declarations): Use warns.
5355         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.

5419         locale files.
5420         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
5421         builddir.
5422         * acinclude.m4: Remove, replaced by the directory m4.
5423         * m4/Makefile.am (EXTRA_DIST): New variable.
