1097 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
1098 * src/output.c (actions_output, guards_output)
1099 (token_definitions_output): No longer keeps track of the output
1100 line number, hence remove the second argument.
1101 (guards_output): Check against the guard member of a rule, not the
1104 (output_skeleton): Don't look for the skeleton location, let m4 do
1106 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
1108 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
1109 (prepare): Given that for the time being changesyntax is not
1110 usable in M4, rename the muscles using `-' to `_'.
1111 Define `defines_flag', `output_parser_name' and `output_header_name'.
1112 * src/output.h (actions_output, guards_output)
1113 (token_definitions_output): Adjust prototypes.
1114 * src/scan-skel.l: Instead of scanning the skeletons, it now
1115 processes the output of m4: `__oline__' and `#output'.
1116 * data/bison.simple: Adjust to be used by M4(sugar).
1117 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
1119 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
1120 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
1121 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
1122 shamelessly stolen from CVS Autoconf.
1124 2002-02-05 Akim Demaille <akim@epita.fr>
1126 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
1127 * configure.in: Check for the declarations of free and malloc.
1128 * src/muscle_tab.c: Adjust.
1130 2002-02-05 Akim Demaille <akim@epita.fr>
1132 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
1133 which have no values.
1135 2002-02-05 Akim Demaille <akim@epita.fr>
1137 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
1140 2002-01-29 Paul Eggert <eggert@twinsun.com>
1142 * src/bison.simple (YYSIZE_T): Do not define merely because
1143 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
1144 On some platforms, <alloca.h> does not declare YYSTD (size_t).
1146 2002-01-27 Akim Demaille <akim@epita.fr>
1148 Fix `%nonassoc and eof'.
1150 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
1151 which were not properly copied! Replace
1152 memcpy (res->errs, src->errs, src->nerrs);
1154 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
1156 * tests/regression.at (%nonassoc and eof): Adjust to newest
1157 Autotest: `.' is not in the PATH.
1159 2002-01-27 Akim Demaille <akim@epita.fr>
1161 * tests/sets.at (AT_EXTRACT_SETS): New.
1165 2002-01-26 Akim Demaille <akim@epita.fr>
1167 * tests/actions.at, tests/calc.at, tests/headers.at,
1168 * tests/torture.at: Adjust to the newest Autotest which no longer
1169 forces `.' in the PATH.
1171 2002-01-25 Akim Demaille <akim@epita.fr>
1173 * tests/regression.at (%nonassoc and eof): New.
1174 Suggested by Robert Anisko.
1176 2002-01-24 Akim Demaille <akim@epita.fr>
1178 Bison dumps core when trying to complain about broken input files.
1179 Reported by Cris van Pelt.
1181 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
1182 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
1184 (Invalid inputs): Strengthen: exercise parse_percent_token.
1186 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
1188 * src/Makefile.am: Add bison.c++.
1189 * src/bison.c++: New skeleton.
1191 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
1195 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
1197 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
1199 2002-01-20 Marc Autret <marc@gnu.org>
1201 * src/files.c (compute_output_file_names): Fix
1203 2002-01-20 Marc Autret <marc@gnu.org>
1205 * tests/output.at: New test.
1206 * src/files.c (compute_base_names): Don't map extensions when
1207 the YACC flag is set, use defaults.
1208 Reported by Evgeny Stambulchik.
1210 2002-01-20 Marc Autret <marc@gnu.org>
1212 * src/system.h: Need to define __attribute__ away for non-GCC
1213 compilers as well (i.e. the vendor C compiler).
1214 Suggested by Albert Chin-A-Young.
1216 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
1218 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
1219 canonical definition.
1220 * src/system.h: Use the canonical definition for PARAMS (avoids
1221 a conflict with the macro from lib/hash.h).
1223 2002-01-11 Akim Demaille <akim@epita.fr>
1225 * configure.in: Use AC_FUNC_STRNLEN.
1226 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
1228 2002-01-09 Akim Demaille <akim@epita.fr>
1230 * src/files.c, src/files.h (output_infix): New.
1231 (tab_extension): Remove.
1232 (compute_base_names): Compute the former, drop the latter.
1233 * src/output.c (prepare): Insert the muscles `output-infix', and
1235 * src/parse-skel.y (string, string.1): New.
1236 (section.header): Use it.
1237 (section.yacc): Remove.
1238 (prefix): Remove too.
1239 * src/scan-skel.l: Adjust.
1240 * src/bison.simple, src/bison.hairy: Adjust.
1242 2002-01-09 Akim Demaille <akim@epita.fr>
1244 * configure.in (WERROR_CFLAGS): Compute it.
1245 * src/Makefile.am (CFLAGS): Pass it.
1246 * tests/atlocal.in (CFLAGS): Idem.
1247 * src/files.c: Fix a few warnings.
1248 (get_extension_index): Remove, unused.
1250 2002-01-08 Akim Demaille <akim@epita.fr>
1252 * src/getargs.c (AS_FILE_NAME): New.
1253 (getargs): Use it to convert DOSish file names.
1254 * src/files.c (base_name): Rename as full_base_name to avoid
1255 clashes with `base_name ()'.
1256 (filename_split): New.
1257 (compute_base_names): N-th rewrite, using filename_split.
1259 2002-01-08 Akim Demaille <akim@epita.fr>
1261 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
1262 New, stolen from the Fileutils 4.1.
1263 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
1264 * configure.in: Check for the presence of memrchr, and of its
1267 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
1269 * lib/hash.h (__P): Added definition for this macro.
1270 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
1271 BUILT_SOURCES, to ensure they are generated first.
1272 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
1273 %error-verbose to allow bootstrapping with bison 1.30x.
1275 2002-01-06 Akim Demaille <akim@epita.fr>
1277 * src/reader.c (parse_braces): Don't fetch the next char, the
1278 convention is to fetch on entry.
1279 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
1280 'switch' without a following semicolon.
1281 * tests/regression.at (braces parsing): New.
1283 2002-01-06 Akim Demaille <akim@epita.fr>
1285 Bison is dead wrong in its RR conflict reports.
1287 * tests/torture.at (GNU Cim Grammar): New.
1288 * src/conflicts.c (count_rr_conflicts): Fix.
1290 2002-01-06 Akim Demaille <akim@epita.fr>
1292 Creating package.m4 from configure.ac causes too many problems.
1294 * tests/Makefile.am (package.m4): Create it by hand,
1295 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
1297 2002-01-06 Akim Demaille <akim@epita.fr>
1299 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
1302 2002-01-04 Paul Eggert <eggert@twinsun.com>
1304 * doc/bison.texinfo (Debugging):
1305 Remove YYSTDERR; it's no longer defined or used.
1306 Also, s/cstdio.h/cstdio/.
1308 2002-01-03 Akim Demaille <akim@epita.fr>
1310 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
1312 2002-01-03 Akim Demaille <akim@epita.fr>
1314 * src/parse-skel.y (process_skeleton): Don't bind the parser's
1315 tracing code to --trace, wait for a better --trace option, with
1318 2002-01-03 Akim Demaille <akim@epita.fr>
1320 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
1321 The ISO C++ standard is extremely clear about it: stderr is
1322 considered a macro, not a regular symbol (see table 94 `Header
1323 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
1324 Therefore std:: does not apply to it. It still does with fprintf.
1325 Also, s/cstdio.h/cstdio/.
1327 2002-01-03 Akim Demaille <akim@epita.fr>
1329 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
1330 for non system headers.
1332 2002-01-02 Akim Demaille <akim@epita.fr>
1334 Equip the skeleton chain with location tracking, runtime trace,
1335 pure parser and scanner.
1337 * src/parse-skel.y: Request a pure parser, locations, and prefix
1339 (%union): Having several members with the same type does not help
1340 type mismatches, simplify.
1341 (YYPRINT, yyprint): New.
1342 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
1345 * src/scan-skel.l: Adjust to these changes.
1346 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
1347 (LOCATION_PRINT, skel_control_t): New.
1349 2001-12-30 Akim Demaille <akim@epita.fr>
1351 * src/parse-skel.y: Get rid of the shift/reduce conflict:
1352 replace `gb' with BLANKS.
1353 * src/scan-skel.l: Adjust.
1355 2001-12-30 Akim Demaille <akim@epita.fr>
1357 * src/system.h: We don't need nor want bcopy.
1358 Throw away MS-DOS crap: we don't need getpid.
1359 * configure.in: We don't need strndup. It was even causing
1360 problems: because Flex includes the headers *before* us,
1361 _GNU_SOURCE is not defined by config.h, and therefore strndup was
1363 * lib/xstrndup.c: New.
1364 * src/scan-skel.l: Use it.
1365 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
1366 * src/parse-skel.y: Use %directives instead of #defines.
1368 2001-12-30 Akim Demaille <akim@epita.fr>
1370 * src/skeleton.h: New.
1371 * src/output.c (output_parser, output_master_parser): Remove, dead
1373 * src/output.h (get_lines_number, actions_output, guards_output)
1374 (token_definitions_output): Prototype them.
1375 * src/parse-skel.y: Add the license notice.
1376 Include output.h and skeleton.h.
1377 (process_skeleton): Returns void, and takes a single parameter.
1378 * src/scan-skel.l: Add the license notice.
1380 Don't use %option yylineno: it seems that then Flex imagines
1381 REJECT has been used, and therefore it won't reallocate its
1382 buffers (which makes no other sense to me than a bug). It results
1383 in warnings for `unused: yy_flex_realloc'.
1385 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
1387 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
1388 (MUSCLE_INSERT_PREFIX): ...to there.
1389 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
1390 (MUSCLE_INSERT_PREFIX): Move from here...
1392 * src/bison.hairy: Add a section directive. Put braces around muscle
1393 names. This parser skeleton is still broken, but Bison should not
1394 choke on a bad muscle 'syntax'.
1395 * src/bison.simple: Add a section directive. Put braces around muscle
1398 * src/files.h (strsuffix, stringappend): Add declarations.
1399 (tab_extension): Add declaration.
1400 (short_base_name): Add declaration.
1402 * src/files.c (strsuffix, stringappend): No longer static. These
1403 functions are used in the skeleton parser.
1404 (tab_extension): New.
1405 (compute_base_names): Use the computations done in this function
1406 to guess if the generated parsers should have '.tab' in their
1408 (short_base_name): No longer static.
1410 * src/output.c (output_skeleton): New.
1411 (output): Disable call to output_master_parser, and give a try to
1412 a new skeleton handling system.
1413 (guards_output, actions_output): No longer static.
1414 (token_definitions_output, get_lines_number): No longer static.
1416 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
1418 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
1421 * src/parse-skel.y: New file.
1422 * src/scan-skel.l: New file.
1424 2001-12-29 Akim Demaille <akim@epita.fr>
1426 %name-prefix is broken.
1428 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
1429 Adjust all dependencies.
1430 * tests/headers.at (export YYLTYPE): Strengthen this test: use
1433 Renaming yylval but not yylloc is not consistent. Now we do.
1435 * src/bison.simple: Prefix yylloc if used.
1436 * doc/bison.texinfo (Decl Summary): Document that.
1438 2001-12-29 Akim Demaille <akim@epita.fr>
1440 * doc/bison.texinfo: Promote `%long-directive' over
1442 Remove all references to fixed-output-files, yacc is enough.
1444 2001-12-29 Akim Demaille <akim@epita.fr>
1446 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
1447 user prologue. These are defaults.
1448 * tests/actions.at (Mid-rule actions): Make sure the user can
1449 define YYDEBUG and YYERROR_VERBOSE.
1451 2001-12-29 Akim Demaille <akim@epita.fr>
1453 * src/output.c (header_output): Don't forget to export YYLTYPE and
1455 * tests/headers.at (export YYLTYPE): New, make sure it does.
1456 * tests/regression.at (%union and --defines, Invalid CPP headers):
1458 * tests/headers.at: here.
1460 2001-12-29 Akim Demaille <akim@epita.fr>
1462 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
1464 2001-12-29 Akim Demaille <akim@epita.fr>
1466 * tests/actions.at (Mid-rule actions): Output on a single line
1469 2001-12-29 Akim Demaille <akim@epita.fr>
1471 * doc/bison.texinfo: Formatting changes.
1473 2001-12-29 Akim Demaille <akim@epita.fr>
1475 Don't store the token defs in a muscle, just be ready to output it
1476 on command. Now possible via `symbols'. Fixes a memory leak.
1478 * src/output.c (token_definitions_output): New.
1479 (output_parser, header_output): Use it.
1480 * src/reader.c (symbols_save): Remove.
1482 2001-12-29 Akim Demaille <akim@epita.fr>
1484 * src/bison.simple: Do not provide a default for YYSTYPE and
1485 YYLTYPE before the user's prologue. Otherwise it's hardly... a
1488 2001-12-29 Akim Demaille <akim@epita.fr>
1490 Mid-rule actions are simply... ignored!
1492 * src/reader.c (readgram): Be sure to attach mid-rule actions to
1493 the empty-rule associated to the dummy symbol, not to the host
1495 * tests/actions.at (Mid-rule actions): New.
1497 2001-12-29 Akim Demaille <akim@epita.fr>
1501 * src/reader.c (reader): Free grammar.
1503 2001-12-29 Akim Demaille <akim@epita.fr>
1507 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
1508 since it allocates it for each state, although only one is needed.
1509 (allocate_storage): Do it here.
1511 2001-12-29 Akim Demaille <akim@epita.fr>
1513 * src/options.h, src/options.c (create_long_option_table): Rename
1515 (long_option_table_new): this, with a clearer prototype.
1516 (percent_table): Remove, unused,
1517 * src/getargs.c (getargs): Adjust.
1519 2001-12-29 Akim Demaille <akim@epita.fr>
1521 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
1522 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
1525 2001-12-29 Akim Demaille <akim@epita.fr>
1527 * src/lalr.c (build_relations): Rename `states' as `states1'.
1528 Sorry, I don't understand exactly what it is, no better name...
1530 2001-12-29 Akim Demaille <akim@epita.fr>
1532 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
1533 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
1534 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
1537 2001-12-29 Akim Demaille <akim@epita.fr>
1539 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
1542 2001-12-29 Akim Demaille <akim@epita.fr>
1544 * src/reader.c, src/reader.h (user_toknums): Remove.
1545 Adjust all users to use symbols[i]->user_token_number.
1547 2001-12-29 Akim Demaille <akim@epita.fr>
1549 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
1550 Adjust all users to use symbols[i]->prec or ->assoc.
1552 2001-12-29 Akim Demaille <akim@epita.fr>
1554 * src/reader.c, src/reader.h (tags): Remove.
1555 Adjust all users to use symbols[i]->tag.
1557 2001-12-29 Akim Demaille <akim@epita.fr>
1559 * src/gram.h, src/gram.c (symbols): New, similar to state_table
1561 * src/reader.c (packsymbols): Fill this table.
1563 * src/conflicts.c (resolve_sr_conflict): Adjust.
1564 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
1566 Use symbols[i]->tag instead of tags[i].
1568 2001-12-29 Akim Demaille <akim@epita.fr>
1570 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
1571 In addition, put a comment in there, to replace...
1572 * tests/regression.at (%union and C comments): Remove.
1574 2001-12-29 Akim Demaille <akim@epita.fr>
1576 * tests/regression.at (Web2c Actions): Blindly move the actual
1577 output as expected output. The contents *seem* right to me, but I
1578 can't pretend reading perfectly parser tables... Nonetheless, all
1579 the other tests pass correctly, the table look OK, even though the
1580 presence of `$axiom' is to be noted: AFAICS it is useless (but
1583 2001-12-29 Akim Demaille <akim@epita.fr>
1585 * src/reader.c (readgram): Don't add the rule 0 if there were no
1586 rules read. In other words, add it _after_ having performed
1587 grammar sanity checks.
1588 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
1590 2001-12-29 Akim Demaille <akim@epita.fr>
1592 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
1593 visible, and some states have now a different number.
1595 2001-12-29 Akim Demaille <akim@epita.fr>
1597 * src/reader.c (readgram): Bind the initial rule's lineno to that
1599 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
1600 (Solved SR Conflicts): Adjust rule 0's line number.
1602 2001-12-29 Akim Demaille <akim@epita.fr>
1604 Fix the `GAWK Grammar' failure.
1606 * src/LR0.c (final_state): Initialize to -1 so that we do compute
1607 the reductions of the first state which was mistakenly confused
1608 with the final state because precisely final_state was initialized
1610 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
1611 now noticed by Bison.
1612 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
1613 have a reduction on $default.
1615 2001-12-29 Akim Demaille <akim@epita.fr>
1617 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
1619 * src/closure.c (print_closure): Likewise.
1620 * src/derives.c (print_derives): Likewise.
1621 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
1624 2001-12-29 Akim Demaille <akim@epita.fr>
1626 * src/lalr.c (lookaheads_print): New.
1627 (lalr): Call it when --trace-flag.
1628 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
1631 2001-12-29 Akim Demaille <akim@epita.fr>
1633 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
1634 when walking through ritem, even via rule->rhs.
1635 * src/reduce.c (dump_grammar, useful_production, reduce_output)
1636 (useful_production, useless_nonterminals): Likewise.
1637 (reduce_grammar_tables): Likewise, plus update nritems.
1638 * src/nullable.c (set_nullable): Likewise.
1639 * src/lalr.c (build_relations): Likewise.
1640 * tests/sets.at (Nullable): Adjust.
1641 Fortunately, now, the $axiom is no longer nullable.
1643 2001-12-29 Akim Demaille <akim@epita.fr>
1645 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
1647 * src/gram.c (ritem_longest_rhs): Likewise.
1648 * src/reduce.c (nonterminals_reduce): Likewise.
1649 * src/print_graph.c (print_graph): Likewise.
1650 * src/output.c (output_rule_data): Likewise.
1651 * src/nullable.c (set_nullable): Likewise.
1653 2001-12-29 Akim Demaille <akim@epita.fr>
1655 * src/output.c: Comment changes.
1657 2001-12-27 Paul Eggert <eggert@twinsun.com>
1659 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
1660 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
1661 Sparc, as they were causing more porting problems than the
1662 (minor) performance improvement was worth.
1664 Also, catch up with 1.31's YYSTD.
1666 2001-12-27 Akim Demaille <akim@epita.fr>
1668 * src/output.c (output_gram): Rely on nritems, not the
1669 0-sentinel. See below.
1670 Use -1 as separator, not 0.
1671 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
1672 Rely on -1 as separator in yyrhs, instead of 0.
1673 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
1674 twice `Now at end of input', therefore there are two lines less to
1677 2001-12-27 Akim Demaille <akim@epita.fr>
1679 * tests/regression.at (Unresolved SR Conflicts):
1680 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
1683 2001-12-27 Akim Demaille <akim@epita.fr>
1685 * src/LR0.c (new_state): Recognize the final state by the fact it
1686 is reached by eoftoken.
1687 (insert_start_shifting_state, insert_eof_shifting_state)
1688 (insert_accepting_state, augment_automaton): Remove, since now
1689 these states are automatically computed from the initial state.
1690 (generate_states): Adjust.
1691 * src/print.c: When reporting a rule number to the user, substract
1692 1, so that the axiom rule is rule 0, and the first user rule is 1.
1693 * src/reduce.c: Likewise.
1694 * src/print_graph.c (print_core): For the time being, just as for
1695 the report, depend upon --trace-flags to dump the full set of
1697 * src/reader.c (readgram): Once the grammar read, insert the rule
1698 0: `$axiom: START-SYMBOL $'.
1699 * tests/set.at: Adjust: rule 0 is now displayed, and since the
1700 number of the states has changed (the final state is no longer
1701 necessarily the last), catch up.
1703 2001-12-27 Akim Demaille <akim@epita.fr>
1705 Try to make the use of the eoftoken valid. Given that its value
1706 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
1707 is used instead of > 0 where appropriate, (ii), depend upon nritems
1708 instead of the 0-sentinel.
1710 * src/gram.h, src/gram.c (nritems): New.
1711 Expected to be duplication of nitems, but for the time being...
1712 * src/reader.c (packgram): Assert nritems and nitems are equal.
1713 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
1714 * src/closure.c (print_closure, print_fderives): Likewise.
1715 * src/gram.c (ritem_print): Likewise.
1716 * src/print.c (print_core, print_grammar): Likewise.
1717 * src/print_graph.c: Likewise.
1719 2001-12-27 Akim Demaille <akim@epita.fr>
1721 * src/main.c (main): If there are complains after grammar
1722 reductions, then output the report anyway if requested, then die.
1723 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
1724 * src/reader.c (eoftoken): New.
1725 (parse_token_decl): If the token being defined has value `0', it
1727 (packsymbols): No longer hack `tags' to insert `$' by hand.
1728 Be sure to preserve the value of the eoftoken.
1729 (reader): Make sure eoftoken is defined.
1730 Initialize nsyms to 0: now eoftoken is created just like the others.
1731 * src/print.c (print_grammar): Don't special case the eof token.
1732 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
1733 lie anyway, albeit pleasant.
1734 * tests/calc.at: Exercise error messages with eoftoken.
1735 Change the grammar so that empty input is invalid.
1736 Adjust expectations.
1737 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
1739 2001-12-27 Akim Demaille <akim@epita.fr>
1741 * configure.in: Check the protos of strchr ans strspn.
1742 Replace strchr if needed.
1743 * src/system.h: Provide the protos of strchr, strspn and memchr if
1745 * lib/strchr.c: New.
1746 * src/reader.c (symbols_save): Use strchr.
1748 2001-12-27 Akim Demaille <akim@epita.fr>
1750 * src/print.c, src/print_graph.c (escape): New.
1751 Use it to quote the TAGS outputs.
1752 * src/print_graph.c (print_state): Now errors are in red, and
1753 reductions in green.
1754 Prefer high to wide: output the state number on a line of its own.
1756 2001-12-27 Akim Demaille <akim@epita.fr>
1758 * src/state.h, src/state.c (reductions_new): New.

1773 * src/conflicts.c (resolve_sr_conflict): Adjust.
1775 2001-12-27 Akim Demaille <akim@epita.fr>
1777 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
1779 2001-12-27 Akim Demaille <akim@epita.fr>
1781 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
1782 * src/print.c: here.
1783 (lookaheadset, shiftset): New, used as additional storage by
1785 (print_results): Adjust.
1786 (print_shifts, print_gotos, print_errs): New, extracted from...
1787 (print_actions): here.
1788 * src/print_graph.c (print_actions): Remove dead code.
1790 2001-12-27 Akim Demaille <akim@epita.fr>
1792 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
1795 2001-12-27 Akim Demaille <akim@epita.fr>
1797 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.

1811 * src/files.c, src/files.h (guard_obstack): Remove.
1812 * src/output.c (output): Adjust.
1813 * src/reader.c (parse_braces): New, factoring...
1814 (copy_action, copy_guard): these two which are renamed as...
1815 (parse_action, parse_guard): these.
1816 As a voluntary consequence, using braces around guards is now
1819 2001-12-27 Akim Demaille <akim@epita.fr>
1821 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
1822 * src/reader.c (symbol_list): `guard' and `guard_line' are new
1824 (symbol_list_new): Adjust.
1825 (copy_action): action_line is the first line, not the last.
1826 (copy_guard): Just as for actions, store the `action' only, not
1827 the switch/case/break flesh.
1828 Don't parse the user action that might follow the guard, let...
1829 (readgram): do it, i.e., now, there can be an action after a
1831 In other words the guard is just explicitly optional.
1833 * src/output.c (guards_output): New.
1834 (output_parser): Call it when needed.
1835 (output): Also free the guard and attrs obstacks.
1836 * src/files.c, src/files.h (obstack_save): Remove.
1837 (output_files): Remove.
1838 As a result, if one needs the former `.act' file, using an
1839 appropriate skeleton which requires actions and guards is now
1841 * src/main.c (main): Adjust.
1842 * tests/semantic.at: New.
1843 * tests/regression.at: Use `input.y' as input file name.
1844 Avoid 8+3 problems by requiring input.c when the test needs the
1847 2001-12-27 Akim Demaille <akim@epita.fr>
1849 * src/reader.c (symbol_list_new): Be sure to initialize all the
1852 2001-12-27 Akim Demaille <akim@epita.fr>
1854 All the hacks using a final pseudo state are now useless.
1856 * src/LR0.c (set_state_table): state_table holds exactly nstates.
1857 * src/lalr.c (nLA): New.
1858 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
1859 instead of lookaheadsp from the pseudo state (nstate + 1).
1861 2001-12-27 Akim Demaille <akim@epita.fr>
1863 * src/output.c (action_row, token_actions): Use a state_t instead
1864 of a integer, and nlookaheads instead of the following state's
1867 2001-12-27 Akim Demaille <akim@epita.fr>
1869 * src/conflicts.c (log_resolution, flush_shift)
1870 (resolve_sr_conflict, set_conflicts, solve_conflicts)
1871 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
1872 (conflicts_print, print_reductions): Use a state_t instead of an
1873 integer when referring to a state.
1874 As much as possible, depend upon nlookaheads, instead of the
1875 `lookaheadsp' member of the following state (since lookaheads of
1876 successive states are successive, the difference between state n + 1
1877 and n served as the number of lookaheads for state n).
1878 * src/lalr.c (add_lookback_edge): Likewise.
1879 * src/print.c (print_core, print_actions, print_state)
1880 (print_results): Likewise.

1887 * src/bison.hairy: Formatting/comment changes.
1889 Remove `register' indications.
1890 Add plenty of `static'.

1894 * src/output.c (prepare): Drop the muscle `ntbase' which
1896 * src/bison.simple: Formatting/comment changes.
1897 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
1898 is an undocumented synonym.
1900 2001-12-22 Akim Demaille <akim@epita.fr>
1902 * src/output.c (output_table_data): Change the prototype to use
1903 `int' for array ranges: some invocations do pass an int, not a
1905 Reported by Wayne Green.
1907 2001-12-22 Akim Demaille <akim@epita.fr>
1909 Some actions of web2c.y are improperly triggered.
1910 Reported by Mike Castle.
1912 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.

1914 (Web2c Report): this.
1915 (Web2c Actions): New.
1917 2001-12-22 Akim Demaille <akim@epita.fr>

1925 2001-12-18 Akim Demaille <akim@epita.fr>
1927 Some host fail on `assert (!"foo")', which expands to
1928 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
1929 Reported by Nelson Beebee.
1931 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
1932 `#define it_succeeded 0' and `assert (it_succeeded)'.
1934 2001-12-17 Marc Autret <autret_m@epita.fr>
1936 * src/bison.simple: Don't hard code the skeleton line and filename.
1937 * src/output.c (output_parser): Rename 'line' as 'output_line'.
1938 New line counter 'skeleton_line' (skeleton-line muscle).
1940 2001-12-17 Paul Eggert <eggert@twinsun.com>
1942 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
1943 YYDEBUG must be defined to a nonzero value.
1945 * src/bison.simple (yytname): Do not assume that the user defines
1946 YYDEBUG to a properly parenthesized expression.
1948 2001-12-17 Akim Demaille <akim@epita.fr>
1950 * src/state.h (state_t): Rename lookaheads as lookaheadsp.

1964 2001-12-17 Akim Demaille <akim@epita.fr>
1966 * src/conflicts.c (print_reductions): Formatting changes.
1968 2001-12-17 Akim Demaille <akim@epita.fr>
1970 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
1971 (flush_reduce): New.
1972 (resolve_sr_conflict): Adjust.
1974 2001-12-17 Akim Demaille <akim@epita.fr>
1976 * src/output.c (output_obstack): Be static and rename as...
1977 (format_obstack): this, to avoid any confusion with files.c's
1979 * src/reader.h (muscle_obstack): Move to...
1980 * src/output.h: here, since it's defined in output.c.
1982 2001-12-17 Akim Demaille <akim@epita.fr>
1984 * src/output.c (action_row, save_column, default_goto)
1985 (sort_actions, matching_state, pack_vector): Better variable
1988 2001-12-17 Akim Demaille <akim@epita.fr>

2000 2001-12-16 Marc Autret <autret_m@epita.fr>
2002 * src/output.c (actions_output): Fix. When we use %no-lines,
2003 there is one less line per action.
2005 2001-12-16 Marc Autret <autret_m@epita.fr>
2007 * src/bison.simple: Remove a useless #line directive.
2008 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
2009 * src/output.c (get_lines_number): New.
2010 (output_parser): Adjust, now takes care about the lines of a
2013 (actions_output): Computes the number of lines taken by actions.
2014 (output_master_parser): Insert new skeleton which is the name of

2027 Make `make distcheck' work.
2029 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
2030 system.h which uses libgettext.h.
2032 2001-12-15 Akim Demaille <akim@epita.fr>
2034 * src/nullable.c (set_nullable): Useless rules must be skipped,
2035 otherwise, since we range over their symbols, we might look at a
2036 nonterminal which no longer ``exists'', i.e., it is not counted in
2037 `nvars', hence we overflow our arrays.
2039 2001-12-15 Akim Demaille <akim@epita.fr>
2041 The header can also be produced directly, without any obstack!
2044 * src/files.c, src/files.h (defines_obstack): Remove.
2045 (compute_header_macro): Global.
2046 (defines_obstack_save): Remove.
2047 * src/reader.c (parse_union_decl): No longer output to
2048 defines_obstack: its content can be found in the `stype' muscle
2050 (output_token_translations): Merge into...
2051 (symbols_output): this.
2053 (symbols_save): this.
2055 * src/output.c (header_output): New.
2058 2001-12-15 Akim Demaille <akim@epita.fr>
2060 * src/reader.c (parse_union_decl): Instead of handling two obstack
2061 simultaneously, use one to define the `stype' muscle, and use the
2062 value of the latter to fill defines_obstack.
2063 (copy_comment): Remove.
2064 (copy_comment2): Work for a single obstack.
2066 (copy_comment): this.
2068 2001-12-15 Akim Demaille <akim@epita.fr>
2070 * src/lex.c, src/lex.h (xgetc): No longer static.
2071 * src/reader.c (parse_union_decl): Revamp.
2073 2001-12-15 Akim Demaille <akim@epita.fr>
2075 Still making progress in separating Bison into (i) input, (ii)
2076 process, (iii) output: now we can directly output the parser file
2077 without using table_obstack at all.
2079 * src/files.c, src/files.h (table_obstack): Bye bye.
2080 (parser_file_name): New.
2081 * src/files.c (compute_output_file_names): Compute it.
2082 * src/output.c (actions_output, output_parser)

2085 2001-12-15 Akim Demaille <akim@epita.fr>
2087 Attach actions to rules, instead of pre-outputting them to
2090 * src/gram.h (rule_t): action and action_line are new members.
2091 * src/reader.c (symbol_list): Likewise.
2092 (copy_action): Save the actions within the rule.
2093 (packgram): Save them in rule_table.
2094 * src/output.c (actions_output): New.
2095 (output_parser): Use it on `%%actions'.
2096 (output_rule_data): Don't free rule_table.
2098 (prepare): Don't save the `action' muscle.
2099 * src/bison.simple: s/%%action/%%actions/.
2101 2001-12-15 Akim Demaille <akim@epita.fr>
2103 * src/reader.c (copy_action): When --yacc, don't append a `;'
2104 to the user action: let it fail if lacking.
2105 Suggested by Arnold Robbins and Tom Tromey.
2107 2001-12-14 Akim Demaille <akim@epita.fr>
2109 * src/lex.c (literalchar): Simply return the char you decoded, non
2110 longer mess around with obstacks and int pointers.
2113 2001-12-14 Akim Demaille <akim@epita.fr>
2115 * src/lex.c (literalchar): Don't escape the special characters,
2116 just decode them, and keep them as char (before, eol was output as
2117 the 2 char string `\n' etc.).
2118 * src/output.c (output_rule_data): Use quotearg to output the
2121 2001-12-13 Paul Eggert <eggert@twinsun.com>
2123 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
2124 Do not infringe on the global user namespace when using C++.
2125 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
2126 All uses of `fprintf' and `stderr' changed.
2128 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
2130 2001-12-13 Akim Demaille <akim@epita.fr>
2132 The computation of nullable is broken: it doesn't handle empty
2135 * tests/torture.at (GNU AWK Grammar): New.
2136 * tests/sets.at (Nullable): New.
2137 * src/nullable.c (set_nullable): Instead of blindly looping over
2138 `ritems', loop over the rules, and then over their rhs's.
2140 Work around Autotest bugs.
2142 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
2143 frame, because Autotest understand lines starting with a `+' as
2144 traces from the shell. Then, they are not processed properly.
2145 Admittedly an Autotest bug, but we don't have time to wait for
2146 Autotest to catch up.
2147 * tests/regression.at (Broken Closure): Adjust to the new table
2150 * tests/sets.at: here.
2152 2001-12-13 Akim Demaille <akim@epita.fr>
2154 * src/closure.c (closure): Use nrules instead of playing tricks
2157 2001-12-13 Akim Demaille <akim@epita.fr>
2159 * src/print.c (print_actions): Output the handling of `$' as the
2160 traces do: shifting the token EOF. Before EOF was treated as a
2162 * tests/regression.at: Adjust some tests.
2163 * src/print_graph.c (print_core): Complete the set of items via
2164 closure. The next-to-final and final states are still unsatisfying,
2165 but that's to be addressed elsewhere.
2166 No longer output the rule numbers, but do output the state number.
2167 A single loop for the shifts + gotos is enough, but picked a
2168 distinct color for each.
2169 (print_graph): Initialize and finalize closure.
2171 2001-12-13 Akim Demaille <akim@epita.fr>
2173 * src/reader.c (readgram): Remove dead code, an strip useless
2175 (get_type): Remove, unused.
2177 2001-12-12 Akim Demaille <akim@epita.fr>
2179 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
2180 on that of lib/error.c.
2182 2001-12-12 Akim Demaille <akim@epita.fr>
2184 Some hosts don't like `/' in includes.
2186 * src/system.h: Include libgettext.h without qualifying the path.
2187 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
2190 2001-12-11 Marc Autret <autret_m@epita.fr>
2192 * src/output.c (output_parser): Remove useless muscle.
2194 2001-12-11 Marc Autret <autret_m@epita.fr>
2196 * src/bison.simple: Remove #line just before %%epilogue. It
2197 is now handled in ...
2198 * src/reader.c (read_additionnal_code): Add the output of a
2199 #line for the epilogue.
2201 2001-12-10 Marc Autret <autret_m@epita.fr>
2203 * src/reader.c (copy_definition): Re-use CPP-outed code which
2204 replace precedent remove.
2205 * src/bison.simple: Remove #line before %%prologue because
2206 %%input-line is wrong at this time.
2208 2001-12-10 Marc Autret <autret_m@epita.fr>
2210 * src/reader.c (symbols_output): Clean up.
2211 * src/output.c (output_gram, output): Clean up.
2213 2001-12-10 Akim Demaille <akim@epita.fr>
2215 * src/lalr.c (initialize_lookaheads): New. Extracted from...
2216 * src/LR0.c (set_state_table): here.
2217 * src/lalr.c (lalr): Call it.
2219 2001-12-10 Akim Demaille <akim@epita.fr>
2221 * src/state.h (shifts): Remove the `number' member: shifts are
2222 attached to state, hence no longer need to be labelled with a
2225 2001-12-10 Akim Demaille <akim@epita.fr>
2227 Now that states have a complete set of members, the linked list of
2228 shifts is useless: just fill directly the state's shifts member.
2230 * src/state.h (shifts): Remove the `next' member.
2231 * src/LR0.c (first_state, last_state): Remove.
2233 (augment_automaton): Don't look for the shifts that must be added
2234 a shift on EOF: it is those of the state we looked for! But now,
2235 since shifts are attached, it is no longer needed to looking
2236 merely by its id: its number.
2238 2001-12-10 Akim Demaille <akim@epita.fr>
2240 * src/LR0.c (augment_automaton): Better variable locality.
2241 Remove an impossible branch: if there is a state corresponding to
2242 the start symbol being shifted, then there is shift for the start
2243 symbol from the initial state.
2245 2001-12-10 Akim Demaille <akim@epita.fr>
2247 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
2248 only when appropriate: when insert_start_shifting_state' is not
2250 * tests/regression.at (Rule Line Numbers): Adjust.
2252 2001-12-10 Akim Demaille <akim@epita.fr>
2254 * src/LR0.c (augment_automaton): Now that all states have shifts,
2255 merge the two cases addition shifts to the initial state.
2257 2001-12-10 Akim Demaille <akim@epita.fr>
2259 * src/lalr.c (set_state_table): Move to...
2261 * src/lalr.c (lalr): Don't call it...
2262 * src/LR0.c (generate_states): do it.
2263 * src/LR0.h (first_state): Remove, only the table is used.
2265 2001-12-10 Akim Demaille <akim@epita.fr>
2267 * src/LR0.h (first_shift, first_reduction): Remove.
2268 * src/lalr.c: Don't use first_shift: find shifts through the
2271 2001-12-10 Akim Demaille <akim@epita.fr>
2273 * src/LR0.c: Attach shifts to states as soon as they are
2275 * src/lalr.c (set_state_table): Instead of assigning shifts to
2276 state, just assert that the mapping was properly done.
2278 2001-12-10 Akim Demaille <akim@epita.fr>
2280 * src/LR0.c (insert_start_shift): Rename as...
2281 (insert_start_shifting_state): this.
2282 (insert_eof_shifting_state, insert_accepting_state): New.
2283 (augment_automaton): Adjust.
2284 Better locality of the variables.
2285 When looking if the start_symbol is shifted from the initial
2286 state, using `while (... symbol != start_symbol ...)' sounds
2287 better than `while (... symbol < start_symbol ...)': If fail
2288 to see how the order between symbols could be relevant!
2290 2001-12-10 Akim Demaille <akim@epita.fr>
2292 * src/getargs.h: Don't declare `spec_name_prefix' and
2293 `spec_file_prefix', declared by src/files.h.
2294 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
2295 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
2296 * src/output.c (prepare): Adjust.
2297 * src/reader.c (symbols_output): Likewise.
2298 * src/vmsgetargs.c: Vaguely adjust, but who cares?
2300 2001-12-10 Akim Demaille <akim@epita.fr>
2302 * src/muscle_tab.c (muscle_init): NULL is a better default than
2305 2001-12-10 Akim Demaille <akim@epita.fr>
2307 * src/reader.c (reader): Calling symbols_output once is enough.
2309 2001-12-10 Akim Demaille <akim@epita.fr>
2311 Now that states have a complete set of members, the linked list of
2312 reductions is useless: just fill directly the state's reductions
2315 * src/state.h (struct reductions): Remove member `number' and
2317 * src/LR0.c (first_reduction, last_reduction): Remove.
2318 (save_reductions): Don't link the new reductions, store them in
2320 * src/lalr.c (set_state_table): No need to attach reductions to
2321 states, it's already done.
2322 * src/output.c (output_actions): No longer free the shifts, then
2323 the reductions, then the states: free all the states and their
2326 2001-12-10 Akim Demaille <akim@epita.fr>
2328 * src/options.c (OPTN, DRTV, BOTH): New.
2329 (option_table): Use them.
2331 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
2332 the job of system.h.
2333 * src/options.c: Don't include stdio.h and xalloc.h for the same
2336 2001-12-10 Akim Demaille <akim@epita.fr>
2338 * src/output.c (output, prepare): Make sure the values of the
2339 muscles `action' and `prologue' are 0-terminated.
2341 2001-12-10 Akim Demaille <akim@epita.fr>
2343 Clean up GCC warnings.
2345 * src/reader.c (copy_action): `buf' is not used.
2346 (parse_skel_decl): Be static.
2347 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
2348 * src/options.h (create_long_option_table): Have a real prototype.
2349 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
2350 (hash_delete_at): Return const void *.
2351 Adjust casts to preserve the const.
2353 2001-12-10 Akim Demaille <akim@epita.fr>
2355 * configure.in: Require 2.52g.
2356 M4 is not needed, but AUTOM4TE is.
2358 * tests/Makefile.am: Adjust.
2360 2001-12-10 Akim Demaille <akim@epita.fr>
2362 One structure for states is enough, even though theoretically
2363 there are LR(0) states and LALR(1) states.
2365 * src/lalr.h (state_t): Remove.
2366 (state_table): Be state_t **, not state_t *.
2367 * src/state.h (core, CORE_ALLOC): Rename as...
2368 (state_t, STATE_ALLOC): this.
2369 Add the LALR(1) members: shifts, reductions, errs.
2370 * src/LR0.c (state_table): Rename as...
2371 (state_hash): this, to avoid name clashes with the global
2373 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
2374 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
2376 2001-12-10 Akim Demaille <akim@epita.fr>
2378 Bison dumps core on bash.y.
2379 Reported by Pascal Bart.
2381 * src/warshall.c (bitmatrix_print): New.
2383 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
2384 j must be the outer loop.
2385 * tests/regression.at (Broken Closure): New.
2387 2001-12-05 Akim Demaille <akim@epita.fr>
2389 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
2391 Reported by Peter Hámorský.
2393 2001-12-05 Akim Demaille <akim@epita.fr>
2395 * src/conflicts.c (err_table): Remove.
2396 (resolve_sr_conflict): Adjust.
2397 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
2399 (state_t.reductions, state_t.shifts): this.
2401 2001-12-05 Akim Demaille <akim@epita.fr>
2403 * src/reduce.c (reduce_grammar_tables): No longer disable the
2404 removal of useless rules via CPP but via `if (0)', so that the
2405 compiler still check the code is valid.
2406 For instance, it should have noticed `rline' no longer exists: use
2407 the `line' member of rule_t.
2408 * src/gram.c (dummy, rline): Remove, unused.
2410 2001-12-05 Akim Demaille <akim@epita.fr>
2412 * src/output.c (pack_vector): Use assert, not berror.
2413 * src/main.c (berror): Remove, unused.
2415 2001-12-05 Akim Demaille <akim@epita.fr>
2417 New experimental feature: if --verbose --trace output all the
2418 items of a state, not only its kernel.
2420 * src/print.c (print_core): If `trace_flag', then invoke closure
2421 before outputting the items of the state (print_core is no longer
2422 a correct name them).
2423 (print_results): Invoke new_closure/free_closure if needed.
2425 2001-12-05 Akim Demaille <akim@epita.fr>
2427 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
2428 * src/closure.c, src/closure.h (itemsetsize): Rename as...
2429 (nitemset): for consistency with the rest of the project.
2431 2001-12-05 Akim Demaille <akim@epita.fr>
2433 * src/closure.c (print_closure): Improve.
2434 (closure): Use it for printing input and output.
2436 2001-12-05 Akim Demaille <akim@epita.fr>
2438 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
2439 indexed by nonterminals.
2441 2001-12-05 Akim Demaille <akim@epita.fr>
2443 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of

2461 * src/output.c (action_row): De-obfuscate
2462 using the good o' techniques: arrays not pointers, variable
2463 locality, BITISSET, RESETBIT etc.
2465 2001-12-05 Akim Demaille <akim@epita.fr>
2467 Pessimize the code to simplify it: from now on, all the states
2468 have a valid SHIFTS, which NSHIFTS is possibly 0.
2470 * src/LR0.c (shifts_new): Be global and move to..
2471 * src/state.c, src/state.h: here.
2472 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
2473 * src/print_graph: Adjust.
2475 2001-12-05 Akim Demaille <akim@epita.fr>
2477 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
2478 * src/conflicts.c: Use it.
2479 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
2480 incorrectly ``simplified''.
2482 2001-12-05 Akim Demaille <akim@epita.fr>
2484 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
2485 using the good o' techniques: arrays not pointers, variable
2486 locality, BITISSET, RESETBIT etc.
2488 2001-12-05 Akim Demaille <akim@epita.fr>
2490 * src/state.h (SHIFT_SYMBOL): New.
2491 * src/conflicts.c: Use it to deobfuscate.
2493 2001-12-05 Akim Demaille <akim@epita.fr>
2495 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
2496 (print_reductions): De-obfuscate using the good o' techniques:
2497 arrays not pointers, variable locality, BITISSET.
2499 2001-12-05 Akim Demaille <akim@epita.fr>
2501 * src/conflicts.c (print_reductions): Arrays, not pointers.
2504 2001-12-05 Akim Demaille <akim@epita.fr>

2516 2001-12-05 Akim Demaille <akim@epita.fr>
2518 * src/conflicts.c (print_reductions): Improve variable locality.
2520 2001-12-05 Akim Demaille <akim@epita.fr>

2527 * src/LR0.c (augment_automaton): Formatting changes.
2528 Better variable locality.

2532 * src/lalr.c (matrix_print): New.
2533 (transpose): Use it.
2534 Use arrays instead of pointers.
2536 2001-12-05 Akim Demaille <akim@epita.fr>
2538 * src/lalr.c (maxrhs): Move to...

2540 * src/lalr.c (build_relations): Adjust.
2542 2001-12-05 Akim Demaille <akim@epita.fr>
2544 * src/lalr.c (transpose): Free the memory allocated to the
2545 argument, as it is replaced by the results by the unique caller.
2546 (build_relations): Merely invoke transpose: it handles the memory
2548 Improve variable locality.
2549 Avoid variables used as mere abbreviations.
2550 (compute_lookaheads): Use arrays instead of pointers.
2552 2001-12-05 Akim Demaille <akim@epita.fr>
2554 * src/lalr.c (initialize_F): Improve variable locality.

2568 2001-12-05 Akim Demaille <akim@epita.fr>
2570 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
2571 the handling of squeue.
2572 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
2574 2001-12-05 Akim Demaille <akim@epita.fr>
2576 Because useless nonterminals are now kept alive (instead of being
2577 `destroyed'), we now sometimes examine them, and store information
2578 related to them. Hence we need to know their number, and adjust
2581 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
2583 * src/LR0.c (allocate_itemsets): The memory allocated to
2584 `symbol_count' was used for two different purpose: once to count
2585 the number of occurrences of each symbol, and later reassigned to
2586 `shift_symbol', containing the symbol that can be shifted from a
2588 Deobfuscate, i.e., allocate, use and free `symbol_count' here
2590 (new_itemsets): Allocate `shift_symbol' here.
2591 (allocate_itemsets): symbol_count includes useless nonterminals.
2593 (free_storage): Use `free', not `XFREE', for pointers that cannot
2596 2001-12-05 Akim Demaille <akim@epita.fr>
2598 * src/nullable.c (set_nullable): Deobfuscate the handling of
2600 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
2602 2001-12-05 Akim Demaille <akim@epita.fr>
2604 * src/gram.c, src/gram.h (ritem_print): New.
2605 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
2606 (This useless function was defined only to work around VMS linkers
2607 that can't handle compilation units with variables only).
2608 * src/reduce.c (dump_grammar): Use it to trace the construction of
2611 2001-12-04 Paul Eggert <eggert@twinsun.com>
2613 * src/bison.simple (union yyalloc): Change member names
2614 to be the same as the stack names.
2615 (yyparse): yyptr is now union yyalloc *, not char *.
2616 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
2617 and may generate better code on some machines.
2618 (yystpcpy): Use prototype if __STDC__ is defined, not just
2619 if __cplusplus is defined.
2621 2001-11-30 Akim Demaille <akim@epita.fr>
2623 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
2624 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
2625 Gettext doesn't compile cleanly, and dies with -Werror.
2626 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
2627 Include WARNING_CFLAGS here.
2628 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
2629 before being defined.
2631 2001-11-27 Paul Eggert <eggert@twinsun.com>
2633 * lib/quotearg.h (quotearg_n, quotearg_n_style):
2634 First arg is int, not unsigned.
2635 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
2636 (SIZE_MAX, UINT_MAX): New macros.
2637 (quotearg_n_options): Abort if N is negative.
2638 Avoid overflow check on hosts where size_t is 64 bits and int
2639 is 32 bits, as overflow is impossible there.
2640 Fix off-by-one typo that caused unnecessary reallocation.
2642 2001-11-29 Paul Eggert <eggert@twinsun.com>
2644 Name space cleanup in generated parser.
2646 * doc/bison.texinfo (Bison Parser): Discuss system headers
2647 and their effect on the user name space.
2650 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
2651 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
2652 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
2654 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
2655 on user names when possible.
2657 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
2658 Simplify test for whather <alloca.h> exists.
2660 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
2662 (<stdio.h>): Include if YYDEBUG.
2664 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
2665 ! defined (yyoverflow) && ! defined (yymemcpy).
2667 (yymemcpy, yyparse): Rename local variables as needed so that
2668 they all begin with 'yy'.
2670 (yystrlen, yystpcpy): New functions.
2672 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
2675 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
2676 instead of relying on string.h functions. Use YYSTACK_ALLOC
2677 and YYSTACK_FREE instead of malloc and free.
2679 2001-11-30 Akim Demaille <akim@epita.fr>
2681 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
2682 before their first uses.
2683 (YYBISON, YYPURE): Move to the top of the output.
2685 2001-11-30 Akim Demaille <akim@epita.fr>
2687 * tests/reduce.at (Useless Nonterminals): Fix.
2689 2001-11-30 Akim Demaille <akim@epita.fr>
2691 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
2692 if body instead of `;' to pacify GCC's warnings.

2739 three stacks, instead of allocating three blocks; this typically is
2740 faster and reduces fragmentation.
2742 Do not limit the number of items in the stack to a value that fits
2743 in 'int', as this is an arbitrary limit on hosts with 64-bit
2744 size_t and 32-bit int.

2807 where all the bits of `ruleset[r]' are set to 0, to make the code

3204 token_buffer not to change.

4904 * src/reader.c (copy_comment2): Expect the input stream to be on

4906 called after `//' or `/*' was read.
4907 (copy_comment, copy_definition, parse_union_decl, copy_action)
4908 (copy_guard): Adjust.
4910 2000-10-16 Akim Demaille <akim@epita.fr>

4934 * doc/bison.texinfo: Various typos spotted by Neil Booth.
4936 2000-10-04 Akim Demaille <akim@epita.fr>
4938 When a literal string is used to define two different tokens,
4939 `bison -v' segfaults.
4940 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
4942 * tests/regression.m4: New file.
4943 Include the core of the sample provided by Piotr Gackiewicz.

4967 translation, move some `\n' out of the translated strings.
4969 2000-10-02 Akim Demaille <akim@epita.fr>
4971 The location tracking mechanism is precious for parse error
4972 messages. Nevertheless, it is enabled only when `@n' is used in
4973 the grammar, which is a different issue (you can use it in error
4974 message, but not in the grammar per se). Therefore, there should
4975 be another means to enable it.
4977 * src/getargs.c (getargs): Support `--locations'.
4979 * src/getargs.h (locationsflag): Export it.
4980 * src/lex.c (percent_table): Support `%locations'.

4990 In addition replace each `flag' with `_flag'.
4992 2000-10-02 Akim Demaille <akim@epita.fr>
4994 Also test parse error messages, including with YYERROR_VERBOSE.
4996 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
4998 Use it to check the computations.
4999 Use it to check `nonassoc' is honored.
5000 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
5001 `--yyerror-verbose'.

5003 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
5005 2000-10-02 Akim Demaille <akim@epita.fr>
5007 Test also `--verbose', `--defines' and `--name-prefix'. Testing
5008 the latter demonstrates a flaw in the handling of non debugging
5009 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
5010 was used in order to simplify:
5026 unfortunately this leads to a CPP conflict when
5027 `--name-prefix=foo' is used since it produces `#define yydebug
5030 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
5031 (YYDPRINTF): New macro.
5033 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
5035 Also test `--verbose', `--defines' and `--name-prefix'.

5039 Improve the readability of the produced parsers.
5041 * src/bison.s1: Formatting changes.
5042 Improve the comment related to the `$' mark.
5043 (yydefault): Don't fall through to `yyresume': `goto' there.
5044 * src/output.c (output_parser): When the `$' is met, skip the end
5046 New variable, `number_of_dollar_signs', to check there's exactly
5047 one `$' in the parser skeleton.
5049 2000-10-02 Akim Demaille <akim@epita.fr>
5051 * lib/xstrdup.c: New file, from the fileutils.

5063 * src/reader.c: Formatting changes.

5065 `reader_output_yylsp'.
5066 * src/symtab.h (symbol_class): New enum type which replaces the
5067 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with

5073 (yaccflag): for consistency and accuracy.
5074 Adjust dependencies.
5076 2000-10-02 Akim Demaille <akim@epita.fr>
5078 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
5079 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
5080 difficult and introduced a lot of core dump. It turns out that
5081 Bison used an implementation of `xmalloc' based on `calloc', and
5082 at various places it does depend upon the initialization to 0. I
5083 have not tried to isolate the pertinent places, and all the former
5084 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
5085 someone should address this issue.
5087 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.

5186 2000-10-02 Akim Demaille <akim@epita.fr>
5188 `user_toknums' is output as a `short[]' in `output.c', while it is
5189 defined as a `int[]' in `reader.c'. For consistency with the
5190 other output tables, `user_toknums' is now defined as a table of

5447 2000-03-17 Akim Demaille <akim@epita.fr>
5449 * src/reader.c (copy_string): New function, factored out from:
5450 (copy_action): Use it.
5451 (copy_guard): Likewise.
5453 2000-03-17 Akim Demaille <akim@epita.fr>
5455 Change the handling of @s so that they behave exactly like $s.
5456 There is now a pseudo variable @$ (readble and writable), location
5457 of the lhs of the rule (by default ranging from the location of
5458 the first symbol of the rhs, to the location of the last symbol,
5459 or, if the rhs is empty, YYLLOC).
5461 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
5463 (yyparse): When providing a default semantic action, provide a
5464 default location action.
5465 (after the $): No longer change `*YYLSP', just stack YYLOC the
5466 same way you stack YYVAL.
5467 * src/reader.c (read_declarations): Use warns.
5468 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.

5491 2000-03-16 Akim Demaille <akim@epita.fr>
5493 * src/bison.s1 [!YYDEBUG]: Define yydebug to 0. This allows to
5494 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
5495 One `#if YYDEBUG' remains, since it uses variables which are
5496 defined only if `YYDEBUG != 0'.
5498 2000-03-16 Akim Demaille <akim@epita.fr>
5500 * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

5522 handled via src/Makefile.am.
5523 (VERSION_STRING, PROTOTYPES, ENABLE_NLS, HAVE_CATGETS,
5524 HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by
5526 * Makefile.am (SUBDIRS): Add m4.

5530 the proper line number and file name.
5531 (DEFS): Propagate the location of bison library files and of the
5533 (INCLUDES): Added `-I ..' so that one can compile with srcdir !=

6167 * src/reader.c (reader_output_yylsp):
6169 (readgram): Use `#if 0' around code that accepted %command
6170 inside grammar rules: The documentation doesn't allow it,
6171 and it will fail since the %command processors scan for the next %.

6173 declaration to allow a multi-character symbol as an alias.
6174 (parse_thong_decl): New function.
6175 (read_declarations): Added %thong declarations.

6179 (skip_to_char, read_declarations, copy_definition)
6180 (parse_token_decl, parse_start_decl, parse_type_decl)

6185 Revised and use multiple warnxxx functions to avoid using VARARGS1.
6186 (read_declarations): Improve the error message for
6187 an invalid character. Do not abort.
6188 (read_declarations, copy_guard, copy_action): Use
6189 printable_version to avoid unprintable characters in printed output.
6190 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
6191 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
6192 Allow the type of a non-terminal can be given
6193 more than once, as long as all specifications give the same type.
6196 (output_headers, output_trailers, output, output_gram)
6197 (output_rule_data): Implement noparserflag variable.
6198 Implement toknumflag variable.
6199 (output): Call reader_output_yylsp to output LTYPESTR.

6213 (safegetc): New function to deal with EOF gracefully.
6214 (literalchar); new function to deal with reading \ escapes.
6215 (lex): Use literalchar.
6216 (lex): Implemented "..." tokens.
6217 (literalchar, lex, parse_percent_token): Made tokenbuffer
6218 always contain the token. This includes growing the token
6219 buffer while reading an integer.
6220 (parse_percent_token): Replaced if-else statement with percent_table.
6221 (parse_percent_token): Added % declarations as another
6222 way to specify the flags -n, -l, and -r. Also added hooks for
6223 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
6224 major changes to files.c.
6225 (lex) Retain in the incoming stream a character following
6227 (skip_white_space, lex): Revised most error messages
6228 and changed fatal to warn to avoid aborting.
6229 (percent_table): Added %thong declarations.
6231 * src/gram.h: Comment changes.
