 881         grammar.
 882         Use more modest sizes, as for the time being the parser does not

 884         of memory.
 885
 886         * tests/torture.at (AT_DATA_LOOKAHEADS_GRAMMAR): Adjust to the

 972
 973         Remove `%thong' support as it is undocumented, unused, duplicates
 974         `%token's job, and creates useless e-mail traffic with people who

1412         (output): Free pre_prologue_obstack and post_prologue_obstack.
1413         * src/files.h, src/files.c (attrs_obstack): Remove.
1414         (pre_prologue_obstack, post_prologue_obstack): New.
1415         * src/reader.c (copy_definition): Add a parameter to specify the
1416         obstack to fill, instead of using attrs_obstack unconditionally.
1417         (read_declarations): Pass pre_prologue_obstack to copy_definition if
1418         `%union' has not yet been seen, pass post_prologue_obstack otherwise.

1421
1422         * data/bison.simple: Remove unnecessary commentary and white
1423         space differences from 1_29-branch.
1424         Depend on YYERROR_VERBOSE, not defined (YYERROR_VERBOSE).
1425
1426         (union yyalloc, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYCOPY,
1427         YYSTACK_RELOCATE): Do not define if yyoverflow is defined, or
1428         if this is a C++ parser and YYSTYPE or YYLTYPE has nontrivial
1429         constructors or destructors.
1430
1431         (yyparse) [! defined YYSTACK_RELOCATE]: Do not relocate the stack.

1442
1443         * src/reduce.c (dump_grammar): Move to...
1444         * src/gram.h, src/gram.c (grammar_dump): here.
1445         Be sure to separate long item numbers.
1446         Don't read the members of a rule's prec if its nil.
1447
1448 2002-04-22  Akim Demaille  <akim@epita.fr>
1449
1450         * src/output.c (table_size, table_grow): New.
1451         (MAXTABLE): Remove, replace uses with table_size.
1452         (pack_vector): Instead of dying when the table is too big, grow it.
1453
1454 2002-04-22  Akim Demaille  <akim@epita.fr>
1455
1456         * data/bison.simple (yyr1): Its type is that of a token number.
1457         * data/bison.c++ (r1_): Likewise.

1459
1460 2002-04-22  Akim Demaille  <akim@epita.fr>
1461
1462         * src/reader.c (token_translations_init): 256 is now the default
1463         value for the error token, i.e., it will be assigned another
1464         number if the user assigned 256 to one of her tokens.
1465         (reader): Don't force 256 to error.
1466         * doc/bison.texinfo (Symbols): Adjust.
1467         * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR)
1468         (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
1469         etc. instead of 10, 20, 30 (which was used to `jump' over error
1470         (256) and undefined (2)).
1471
1472 2002-04-22  Akim Demaille  <akim@epita.fr>
1473
1474         Propagate more token_number_t.

1477         (item_number_as_token_number): New.
1478         * src/output.c (GENERATE_OUTPUT_TABLE): New.
1479         Use it to create output_item_number_table and
1480         output_token_number_table.

1487
1488         * src/output.h, src/output.c (get_lines_number): Remove.
1489
1490 2002-04-19  Akim Demaille  <akim@epita.fr>
1491
1492         * doc/bison.texinfo (Actions): Make clear that `|' is not the same
1493         as Lex/Flex'.
1494         (Debugging): More details about enabling the debugging features.
1495         (Table of Symbols): Describe $$, $n, @$, and @n.
1496         Suggested by Tim Josling.
1497
1498 2002-04-19  Akim Demaille  <akim@epita.fr>
1499
1500         * doc/bison.texinfo: Remove the uses of the obsolete @refill.

1503
1504         * src/system.h: Rely on HAVE_LIMITS_H.
1505         Suggested by Paul Eggert.
1506
1507 2002-04-09  Akim Demaille  <akim@epita.fr>
1508
1509         * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
1510         full stderr, and strip it according to the bison options, instead
1511         of composing the error message from different bits.
1512         This makes it easier to check for several error messages.
1513         Adjust all the invocations.
1514         Add an invocation exercising the error token.
1515         Add an invocation demonstrating a stupid error message.
1516         (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.
1517         Adjust the tests.
1518         Error message are for stderr, not stdout.
1519
1520 2002-04-09  Akim Demaille  <akim@epita.fr>
1521
1522         * src/gram.h, src/gram.c (error_token_number): Remove, use
1523         errtoken->number.
1524         * src/reader.c (reader): Don't specify the user token number (2)
1525         for $undefined, as it uselessly prevents using it.
1526         * src/gram.h (token_number_t): Move to...
1527         * src/symtab.h: here.
1528         (state_t.number): Is a token_number_t.
1529         * src/print.c, src/reader.c: Use undeftoken->number instead of
1530         hard coded 2.
1531         (Even though this 2 is not the same as above: the number of the
1532         undeftoken remains being 2, it is its user token number which
1533         might not be 2).
1534         * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
1535         `user_token_number_max'.
1536         Output `undef_token_number'.
1537         * data/bison.simple, data/bison.c++: Use them.
1538         Be sure to map invalid yylex return values to
1539         `undef_token_number'.  This saves us from gratuitous SEGV.
1540
1541         * tests/conflicts.at (Solved SR Conflicts)
1542         (Unresolved SR Conflicts): Adjust.
1543         * tests/regression.at (Web2c Actions): Adjust.

1546
1547         * data/bison.c++: s/b4_item_number_max/b4_rhs_number_max/.
1548         Adding #line.
1549         Remove the duplicate `typedefs'.
1550         (RhsNumberType): Fix the declaration and various other typos.
1551         Use __ofile__.
1552         * data/bison.simple: Use __ofile__.
1553         * src/scan-skel.l: Handle __ofile__.
1554
1555 2002-04-08  Akim Demaille  <akim@epita.fr>
1556
1557         * src/gram.h (item_number_t): New, the type of item numbers in
1558         RITEM.  Note that it must be able to code symbol numbers as
1559         positive number, and the negation of rule numbers as negative
1560         numbers.
1561         Adjust all dependencies (pretty many).
1562         * src/reduce.c (rule): Remove this `short *' pointer: use
1563         item_number_t.
1564         * src/system.h (MINSHORT, MAXSHORT): Remove.
1565         Include `limits.h'.
1566         Adjust dependencies to using SHRT_MAX and SHRT_MIN.
1567         (shortcpy): Remove.
1568         (MAXTABLE): Move to...
1569         * src/output.c (MAXTABLE): here.
1570         (prepare_rules): Use output_int_table to output rhs.
1571         * data/bison.simple, data/bison.c++: Adjust.
1572         * tests/torture.at (Big triangle): Move the limit from 254 to
1573         500.
1574         * tests/regression.at (Web2c Actions): Ajust.
1575
1576         Trying with bigger grammars shows various phenomena: at 3000 (28Mb
1577         of grammar file) bison is killed by my system, at 2000 (12Mb) bison
1578         passes, but produces negative #line number, once fixed, GCC is
1579         killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
1580         C), it passes.
1581         * src/state.h (state_h): Code input lines on ints, not shorts.
1582
1583 2002-04-08  Akim Demaille  <akim@epita.fr>
1584
1585         * src/reduce.c (reduce_grammar): First reduce the nonterminals,

1598         New.
1599         Use them to define yy_token_number_type/TokenNumberType.
1600         Use this type for yytranslate.
1601         * tests/torture.at (Big triangle): Push the limit from 124 to

1676         to the bucket giving the priority/associativity.
1677         Member `associativity' removed: useless.

1706
1707         * src/reduce.c (reduce_grammar_tables): Don't sort RITEM.
1708
1709 2002-04-07  Akim Demaille  <akim@epita.fr>
1710
1711         Be sure never to walk through RITEMS, but use only data related to
1712         the rules themselves. RITEMS should be banished.
1713
1714         * src/output.c (output_token_translations): Rename as...
1715         (prepare_tokens): this.
1716         In addition to `translate', prepare the muscles `tname' and
1717         `toknum', which were handled by...
1718         (output_rule_data): this.
1719         Remove, and move the remainder of its outputs into...
1720         (prepare_rules): this new routines, which also merges content from

1729
1730         * src/LR0.c (new_state): Display `nstates' as the name of the
1731         newly created state.
1732         Adjust to initialize first_state and last_state if needed.
1733         Be sure to distinguish the initial from the final state.
1734         (new_states): Create the itemset of the initial state, and use
1735         new_state.
1736         * src/closure.c (closure): Now that the initial state has its
1737         items properly set, there is no need for a special case when
1738         creating `ruleset'.
1739
1740         As a result, now the rule 0, reducing to $axiom, is visible in the
1741         outputs.  Adjust the test suite.

2082         causing more problems than it was curing, since it didn't work

2098 2002-02-14  Akim Demaille  <akim@epita.fr>
2099
2100         * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c.
2101
2102 2002-02-13  Andreas Schwab  <schwab@suse.de>
2103
2104         * src/output.c (output_rule_data): Don't output NULL, it might
2105         not be defined yet.
2106
2107 2002-02-11  Robert Anisko  <robert@lrde.epita.fr>
2108
2109         * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
2110         (Copyright notice): Update.
2111
2112 2002-02-11  Akim Demaille  <akim@epita.fr>
2113
2114         * tests/regression.at (%nonassoc and eof): Don't include
2115         nonportable headers.
2116
2117 2002-02-08  Robert Anisko  <robert@lrde.epita.fr>
2118
2119         * data/bison.c++: Correct error recovery.  Make the user able to
2120         initialize the starting location.
2121
2122 2002-02-07  Akim Demaille  <akim@epita.fr>
2123
2124         * tests/input.at: New.
2125
2126 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
2127
2128         * data/bison.c++: Replace some direct m4 expansions by constants.  Be
2129         more consistent when naming methods and variables.  Put preprocessor
2130         directives around tables only needed for debugging.
2131
2132 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
2133
2134         * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
2135         C++ parsers.
2136         (yy::b4_name::parse): Use print_.
2137
2138 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
2139
2140         * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
2141
2142 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
2143
2144         * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
2145         C++ parsers.
2146         (yy::b4_name::parse): Build verbose error messages, and use error_.
2147
2148 2002-02-06  Robert Anisko  <robert@lrde.epita.fr>
2149
2150         * data/bison.c++: Fix m4 quoting in comments.
2151
2152 2002-02-06  Robert Anisko  <robert@lrde.epita.fr>
2153
2154         * data/bison.c++: Adjust the parser code.  Fix some muscles that were
2155         not expanded by m4.
2156
2157 2002-02-05  Akim Demaille  <akim@epita.fr>
2158
2159         * data/bison.c++: Adjust to the M4 back end.
2160         More is certainly needed.
2161
2162 2002-02-05  Akim Demaille  <akim@epita.fr>
2163
2164         Give a try to M4 as a back end.
2165
2166         * lib/readpipe.c: New, from wdiff.
2167         * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
2168         BISON_HAIRY.
2169         * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
2170         specific values.  Now it is m4 that performs the lookup.
2171         * src/parse-skel.y: Remove.
2172         * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
2173         * src/output.c (actions_output, guards_output)
2174         (token_definitions_output): No longer keeps track of the output
2175         line number, hence remove the second argument.
2176         (guards_output): Check against the guard member of a rule, not the
2177         action member.
2178         Adjust callers.
2179         (output_skeleton): Don't look for the skeleton location, let m4 do
2180         that.
2181         Create `/tmp/muscles.m4'.  This is temporary, a proper temporary
2182         file will be used.
2183         Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
2184         (prepare): Given that for the time being changesyntax is not
2185         usable in M4, rename the muscles using `-' to `_'.
2186         Define `defines_flag', `output_parser_name' and `output_header_name'.
2187         * src/output.h (actions_output, guards_output)
2188         (token_definitions_output): Adjust prototypes.
2189         * src/scan-skel.l: Instead of scanning the skeletons, it now
2190         processes the output of m4: `__oline__' and `#output'.
2191         * data/bison.simple: Adjust to be used by M4(sugar).
2192         * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
2193         to date.
2194         * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
2195         instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
2196         * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
2197         shamelessly stolen from CVS Autoconf.
2198
2199 2002-02-05  Akim Demaille  <akim@epita.fr>
2200
2201         * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
2202         * configure.in: Check for the declarations of free and malloc.
2203         * src/muscle_tab.c: Adjust.
2204
2205 2002-02-05  Akim Demaille  <akim@epita.fr>
2206
2207         * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
2208         which have no values.
2209
2210 2002-02-05  Akim Demaille  <akim@epita.fr>
2211
2212         * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
2213         * data/: here.
2214
2215 2002-01-29  Paul Eggert  <eggert@twinsun.com>
2216
2217         * src/bison.simple (YYSIZE_T): Do not define merely because
2218         YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
2219         On some platforms, <alloca.h> does not declare YYSTD (size_t).
2220
2221 2002-01-27  Akim Demaille  <akim@epita.fr>
2222
2223         Fix `%nonassoc and eof'.
2224
2225         * src/state.c (errs_dup): Aaaah!  The failure was due to bytes
2226         which were not properly copied!  Replace
2227         memcpy (res->errs, src->errs, src->nerrs);
2228         with
2229         memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
2230         !!!
2231         * tests/regression.at (%nonassoc and eof): Adjust to newest
2232         Autotest: `.' is not in the PATH.
2233
2234 2002-01-27  Akim Demaille  <akim@epita.fr>
2235
2236         * tests/sets.at (AT_EXTRACT_SETS): New.
2237         (Nullable): Use it.
2238         (Firsts): New.
2239
2240 2002-01-26  Akim Demaille  <akim@epita.fr>
2241
2242         * tests/actions.at, tests/calc.at, tests/headers.at,
2243         * tests/torture.at: Adjust to the newest Autotest which no longer
2244         forces `.' in the PATH.
2245
2246 2002-01-25  Akim Demaille  <akim@epita.fr>
2247
2248         * tests/regression.at (%nonassoc and eof): New.
2249         Suggested by Robert Anisko.
2250
2251 2002-01-24  Akim Demaille  <akim@epita.fr>
2252
2253         Bison dumps core when trying to complain about broken input files.
2254         Reported by Cris van Pelt.
2255
2256         * src/lex.c (parse_percent_token): Be sure to set token_buffer.
2257         * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
2258         into...
2259         (Invalid inputs): Strengthen: exercise parse_percent_token.
2260
2261 2002-01-24  Robert Anisko  <robert.anisko@epita.fr>
2262
2263         * src/Makefile.am: Add bison.c++.
2264         * src/bison.c++: New skeleton.
2265
2266 2002-01-21  Paolo Bonzini <bonzini@gnu.org>
2267
2268         * po/it.po: New.
2269
2270 2002-01-21  Kees Zeelenberg  <kzlg@users.sourceforge.net>
2271
2272         * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
2273
2274 2002-01-20  Marc Autret  <marc@gnu.org>
2275
2276         * src/files.c (compute_output_file_names): Fix
2277
2278 2002-01-20  Marc Autret  <marc@gnu.org>
2279
2280         * tests/output.at: New test.
2281         * src/files.c (compute_base_names): Don't map extensions when
2282         the YACC flag is set, use defaults.
2283         Reported by Evgeny Stambulchik.
2284
2285 2002-01-20  Marc Autret  <marc@gnu.org>
2286
2287         * src/system.h: Need to define __attribute__ away for non-GCC
2288         compilers as well (i.e. the vendor C compiler).
2289         Suggested by Albert Chin-A-Young.
2290
2291 2002-01-11  Tim Van Holder  <tim.van.holder@pandora.be>
2292
2293         * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
2294         canonical definition.
2295         * src/system.h: Use the canonical definition for PARAMS (avoids
2296         a conflict with the macro from lib/hash.h).
2297
2298 2002-01-11  Akim Demaille  <akim@epita.fr>
2299
2300         * configure.in: Use AC_FUNC_STRNLEN.
2301         Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
2302
2303 2002-01-09  Akim Demaille  <akim@epita.fr>
2304
2305         * src/files.c, src/files.h (output_infix): New.
2306         (tab_extension): Remove.
2307         (compute_base_names): Compute the former, drop the latter.
2308         * src/output.c (prepare): Insert the muscles `output-infix', and
2309         `output-suffix'.
2310         * src/parse-skel.y (string, string.1): New.
2311         (section.header): Use it.
2312         (section.yacc): Remove.
2313         (prefix): Remove too.
2314         * src/scan-skel.l: Adjust.
2315         * src/bison.simple, src/bison.hairy: Adjust.
2316
2317 2002-01-09  Akim Demaille  <akim@epita.fr>
2318
2319         * configure.in (WERROR_CFLAGS): Compute it.
2320         * src/Makefile.am (CFLAGS): Pass it.
2321         * tests/atlocal.in (CFLAGS): Idem.
2322         * src/files.c: Fix a few warnings.
2323         (get_extension_index): Remove, unused.
2324
2325 2002-01-08  Akim Demaille  <akim@epita.fr>
2326
2327         * src/getargs.c (AS_FILE_NAME): New.
2328         (getargs): Use it to convert DOSish file names.
2329         * src/files.c (base_name): Rename as full_base_name to avoid
2330         clashes with `base_name ()'.
2331         (filename_split): New.
2332         (compute_base_names): N-th rewrite, using filename_split.
2333
2334 2002-01-08  Akim Demaille  <akim@epita.fr>
2335
2336         * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
2337         New, stolen from the Fileutils 4.1.
2338         * lib/Makefile.am (libbison_a_SOURCES): Adjust.
2339         * configure.in: Check for the presence of memrchr, and of its
2340         prototype.
2341
2342 2002-01-07  Tim Van Holder  <tim.van.holder@pandora.be>
2343
2344         * lib/hash.h (__P): Added definition for this macro.
2345         * src/Makefile.am: Add parse-skel.c and scan-skel.c to
2346         BUILT_SOURCES, to ensure they are generated first.
2347         * src/parse-skel.y: Use YYERROR_VERBOSE instead of
2348         %error-verbose to allow bootstrapping with bison 1.30x.
2349
2350 2002-01-06  Akim Demaille  <akim@epita.fr>
2351
2352         * src/reader.c (parse_braces): Don't fetch the next char, the
2353         convention is to fetch on entry.
2354         * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
2355         'switch' without a following semicolon.
2356         * tests/regression.at (braces parsing): New.
2357
2358 2002-01-06  Akim Demaille  <akim@epita.fr>
2359
2360         Bison is dead wrong in its RR conflict reports.
2361
2362         * tests/torture.at (GNU Cim Grammar): New.
2363         * src/conflicts.c (count_rr_conflicts): Fix.
2364
2365 2002-01-06  Akim Demaille  <akim@epita.fr>
2366
2367         Creating package.m4 from configure.ac causes too many problems.
2368
2369         * tests/Makefile.am (package.m4): Create it by hand,
2370         AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
2371
2372 2002-01-06  Akim Demaille  <akim@epita.fr>
2373
2374         * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
2375         skeleton.h.
2376
2377 2002-01-04  Paul Eggert  <eggert@twinsun.com>
2378
2379         * doc/bison.texinfo (Debugging):
2380         Remove YYSTDERR; it's no longer defined or used.
2381         Also, s/cstdio.h/cstdio/.
2382
2383 2002-01-03  Akim Demaille  <akim@epita.fr>
2384
2385         * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
2386
2387 2002-01-03  Akim Demaille  <akim@epita.fr>
2388
2389         * src/parse-skel.y (process_skeleton): Don't bind the parser's
2390         tracing code to --trace, wait for a better --trace option, with
2391         args.
2392
2393 2002-01-03  Akim Demaille  <akim@epita.fr>
2394
2395         * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
2396         The ISO C++ standard is extremely clear about it: stderr is
2397         considered a macro, not a regular symbol (see table 94 `Header
2398         <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
2399         Therefore std:: does not apply to it.  It still does with fprintf.
2400         Also, s/cstdio.h/cstdio/.
2401
2402 2002-01-03  Akim Demaille  <akim@epita.fr>
2403
2404         * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
2405         for non system headers.
2406
2407 2002-01-02  Akim Demaille  <akim@epita.fr>
2408
2409         Equip the skeleton chain with location tracking, runtime trace,
2410         pure parser and scanner.
2411
2412         * src/parse-skel.y: Request a pure parser, locations, and prefix
2413         renaming.
2414         (%union): Having several members with the same type does not help
2415         type mismatches, simplify.
2416         (YYPRINT, yyprint): New.
2417         (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
2418         (skel_error): this.
2419         Handle locations.
2420         * src/scan-skel.l: Adjust to these changes.
2421         * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
2422         (LOCATION_PRINT, skel_control_t): New.
2423
2424 2001-12-30  Akim Demaille  <akim@epita.fr>
2425
2426         * src/parse-skel.y: Get rid of the shift/reduce conflict:
2427         replace `gb' with BLANKS.
2428         * src/scan-skel.l: Adjust.
2429
2430 2001-12-30  Akim Demaille  <akim@epita.fr>
2431
2432         * src/system.h: We don't need nor want bcopy.
2433         Throw away MS-DOS crap: we don't need getpid.
2434         * configure.in: We don't need strndup.  It was even causing
2435         problems: because Flex includes the headers *before* us,
2436         _GNU_SOURCE is not defined by config.h, and therefore strndup was
2437         not visible.
2438         * lib/xstrndup.c: New.
2439         * src/scan-skel.l: Use it.
2440         Be sure to initialize yylval.muscle member when scanning a MUSCLE.
2441         * src/parse-skel.y: Use %directives instead of #defines.
2442
2443 2001-12-30  Akim Demaille  <akim@epita.fr>
2444
2445         * src/skeleton.h: New.
2446         * src/output.c (output_parser, output_master_parser): Remove, dead
2447         code.
2448         * src/output.h (get_lines_number, actions_output, guards_output)
2449         (token_definitions_output): Prototype them.
2450         * src/parse-skel.y: Add the license notice.
2451         Include output.h and skeleton.h.
2452         (process_skeleton): Returns void, and takes a single parameter.
2453         * src/scan-skel.l: Add the license notice.
2454         Include skeleton.h.
2455         Don't use %option yylineno: it seems that then Flex imagines
2456         REJECT has been used, and therefore it won't reallocate its
2457         buffers (which makes no other sense to me than a bug).  It results
2458         in warnings for `unused: yy_flex_realloc'.

2460 2001-12-30  Robert Anisko  <robert.anisko@epita.fr>
2461
2462         * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
2463         (MUSCLE_INSERT_PREFIX): ...to there.
2464         * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
2465         (MUSCLE_INSERT_PREFIX): Move from here...
2466
2467         * src/bison.hairy: Add a section directive.  Put braces around muscle
2468         names.  This parser skeleton is still broken, but Bison should not
2469         choke on a bad muscle 'syntax'.
2470         * src/bison.simple: Add a section directive.  Put braces around muscle
2471         names.
2472
2473         * src/files.h (strsuffix, stringappend): Add declarations.
2474         (tab_extension): Add declaration.
2475         (short_base_name): Add declaration.
2476
2477         * src/files.c (strsuffix, stringappend): No longer static.  These
2478         functions are used in the skeleton parser.
2479         (tab_extension): New.
2480         (compute_base_names): Use the computations done in this function
2481         to guess if the generated parsers should have '.tab' in their
2482         names.
2483         (short_base_name): No longer static.
2484
2485         * src/output.c (output_skeleton): New.
2486         (output): Disable call to output_master_parser, and give a try to
2487         a new skeleton handling system.
2488         (guards_output, actions_output): No longer static.
2489         (token_definitions_output, get_lines_number): No longer static.
2490
2491         * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
2492
2493         * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
2494         parse-skel.y.
2495
2496         * src/parse-skel.y: New file.
2497         * src/scan-skel.l: New file.
2498
2499 2001-12-29  Akim Demaille  <akim@epita.fr>
2500
2501         %name-prefix is broken.
2502
2503         * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
2504         Adjust all dependencies.
2505         * tests/headers.at (export YYLTYPE): Strengthen this test: use
2506         %name-prefix.
2507
2508         Renaming yylval but not yylloc is not consistent.  Now we do.
2509
2510         * src/bison.simple: Prefix yylloc if used.
2511         * doc/bison.texinfo (Decl Summary): Document that.
2512
2513 2001-12-29  Akim Demaille  <akim@epita.fr>
2514
2515         * doc/bison.texinfo: Promote `%long-directive' over
2516         `%long_directive'.
2517         Remove all references to fixed-output-files, yacc is enough.
2518
2519 2001-12-29  Akim Demaille  <akim@epita.fr>
2520
2521         * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
2522         user prologue.  These are defaults.
2523         * tests/actions.at (Mid-rule actions): Make sure the user can
2524         define YYDEBUG and YYERROR_VERBOSE.
2525
2526 2001-12-29  Akim Demaille  <akim@epita.fr>
2527
2528         * src/output.c (header_output): Don't forget to export YYLTYPE and
2529         yylloc.
2530         * tests/headers.at (export YYLTYPE): New, make sure it does.
2531         * tests/regression.at (%union and --defines, Invalid CPP headers):
2532         Move to...
2533         * tests/headers.at: here.
2534
2535 2001-12-29  Akim Demaille  <akim@epita.fr>
2536
2537         * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
2538
2539 2001-12-29  Akim Demaille  <akim@epita.fr>
2540
2541         * tests/actions.at (Mid-rule actions): Output on a single line
2542         instead of several.
2543
2544 2001-12-29  Akim Demaille  <akim@epita.fr>
2545
2546         * doc/bison.texinfo: Formatting changes.
2547
2548 2001-12-29  Akim Demaille  <akim@epita.fr>
2549
2550         Don't store the token defs in a muscle, just be ready to output it
2551         on command.  Now possible via `symbols'.  Fixes a memory leak.
2552
2553         * src/output.c (token_definitions_output): New.
2554         (output_parser, header_output): Use it.
2555         * src/reader.c (symbols_save): Remove.
2556
2557 2001-12-29  Akim Demaille  <akim@epita.fr>
2558
2559         * src/bison.simple: Do not provide a default for YYSTYPE and
2560         YYLTYPE before the user's prologue.  Otherwise it's hardly... a
2561         default.
2562
2563 2001-12-29  Akim Demaille  <akim@epita.fr>
2564
2565         Mid-rule actions are simply... ignored!
2566
2567         * src/reader.c (readgram): Be sure to attach mid-rule actions to
2568         the empty-rule associated to the dummy symbol, not to the host
2569         rule.
2570         * tests/actions.at (Mid-rule actions): New.
2571
2572 2001-12-29  Akim Demaille  <akim@epita.fr>
2573
2574         Memory leak.
2575
2576         * src/reader.c (reader): Free grammar.
2577
2578 2001-12-29  Akim Demaille  <akim@epita.fr>
2579
2580         Memory leak.
2581
2582         * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
2583         since it allocates it for each state, although only one is needed.
2584         (allocate_storage): Do it here.
2585
2586 2001-12-29  Akim Demaille  <akim@epita.fr>
2587
2588         * src/options.h, src/options.c (create_long_option_table): Rename
2589         as...
2590         (long_option_table_new): this, with a clearer prototype.
2591         (percent_table): Remove, unused,
2592         * src/getargs.c (getargs): Adjust.
2593
2594 2001-12-29  Akim Demaille  <akim@epita.fr>
2595
2596         * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
2597         * src/print.c, src/print_graph.c, src/state.h: Rename state_table
2598         as states.
2599
2600 2001-12-29  Akim Demaille  <akim@epita.fr>
2601
2602         * src/lalr.c (build_relations): Rename `states' as `states1'.
2603         Sorry, I don't understand exactly what it is, no better name...
2604
2605 2001-12-29  Akim Demaille  <akim@epita.fr>
2606
2607         * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
2608         * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
2609         * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
2610         as rules.
2611
2612 2001-12-29  Akim Demaille  <akim@epita.fr>
2613
2614         * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
2615         ago.
2616
2617 2001-12-29  Akim Demaille  <akim@epita.fr>
2618
2619         * src/reader.c, src/reader.h (user_toknums): Remove.
2620         Adjust all users to use symbols[i]->user_token_number.
2621
2622 2001-12-29  Akim Demaille  <akim@epita.fr>
2623
2624         * src/gram.c, src/gram.h (sprec, sassoc): Remove.
2625         Adjust all users to use symbols[i]->prec or ->assoc.
2626
2627 2001-12-29  Akim Demaille  <akim@epita.fr>
2628
2629         * src/reader.c, src/reader.h (tags): Remove.
2630         Adjust all users to use symbols[i]->tag.
2631
2632 2001-12-29  Akim Demaille  <akim@epita.fr>
2633
2634         * src/gram.h, src/gram.c (symbols): New, similar to state_table
2635         and rule_table.
2636         * src/reader.c (packsymbols): Fill this table.
2637         Drop sprec.
2638         * src/conflicts.c (resolve_sr_conflict): Adjust.
2639         * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
2640         single table.
2641         Use symbols[i]->tag instead of tags[i].
2642
2643 2001-12-29  Akim Demaille  <akim@epita.fr>
2644
2645         * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
2646         In addition, put a comment in there, to replace...
2647         * tests/regression.at (%union and C comments): Remove.
2648
2649 2001-12-29  Akim Demaille  <akim@epita.fr>
2650
2651         * tests/regression.at (Web2c Actions): Blindly move the actual
2652         output as expected output.  The contents *seem* right to me, but I
2653         can't pretend reading perfectly parser tables...  Nonetheless, all
2654         the other tests pass correctly, the table look OK, even though the
2655         presence of `$axiom' is to be noted: AFAICS it is useless (but
2656         harmless).
2657
2658 2001-12-29  Akim Demaille  <akim@epita.fr>
2659
2660         * src/reader.c (readgram): Don't add the rule 0 if there were no
2661         rules read.  In other words, add it _after_ having performed
2662         grammar sanity checks.
2663         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
2664
2665 2001-12-29  Akim Demaille  <akim@epita.fr>
2666
2667         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
2668         visible, and some states have now a different number.
2669
2670 2001-12-29  Akim Demaille  <akim@epita.fr>
2671
2672         * src/reader.c (readgram): Bind the initial rule's lineno to that
2673         of the first rule.
2674         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
2675         (Solved SR Conflicts): Adjust rule 0's line number.
2676
2677 2001-12-29  Akim Demaille  <akim@epita.fr>
2678
2679         Fix the `GAWK Grammar' failure.
2680
2681         * src/LR0.c (final_state): Initialize to -1 so that we do compute
2682         the reductions of the first state which was mistakenly confused
2683         with the final state because precisely final_state was initialized
2684         to 0.
2685         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
2686         now noticed by Bison.
2687         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
2688         have a reduction on $default.
2689
2690 2001-12-29  Akim Demaille  <akim@epita.fr>
2691
2692         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
2693         rule line numbers.
2694         * src/closure.c (print_closure): Likewise.
2695         * src/derives.c (print_derives): Likewise.
2696         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
2697         now.
2698
2699 2001-12-29  Akim Demaille  <akim@epita.fr>
2700
2701         * src/lalr.c (lookaheads_print): New.
2702         (lalr): Call it when --trace-flag.
2703         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
2704         are dumped.
2705
2706 2001-12-29  Akim Demaille  <akim@epita.fr>
2707
2708         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
2709         when walking through ritem, even via rule->rhs.
2710         * src/reduce.c (dump_grammar, useful_production, reduce_output)
2711         (useful_production, useless_nonterminals): Likewise.
2712         (reduce_grammar_tables): Likewise, plus update nritems.
2713         * src/nullable.c (set_nullable): Likewise.
2714         * src/lalr.c (build_relations): Likewise.
2715         * tests/sets.at (Nullable): Adjust.
2716         Fortunately, now, the $axiom is no longer nullable.
2717
2718 2001-12-29  Akim Demaille  <akim@epita.fr>
2719
2720         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
2721         the 0-sentinel.
2722         * src/gram.c (ritem_longest_rhs): Likewise.
2723         * src/reduce.c (nonterminals_reduce): Likewise.
2724         * src/print_graph.c (print_graph): Likewise.
2725         * src/output.c (output_rule_data): Likewise.
2726         * src/nullable.c (set_nullable):  Likewise.
2727
2728 2001-12-29  Akim Demaille  <akim@epita.fr>
2729
2730         * src/output.c: Comment changes.
2731
2732 2001-12-27  Paul Eggert  <eggert@twinsun.com>
2733
2734         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
2735         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
2736         Sparc, as they were causing more porting problems than the
2737         (minor) performance improvement was worth.
2738
2739         Also, catch up with 1.31's YYSTD.
2740
2741 2001-12-27  Akim Demaille  <akim@epita.fr>
2742
2743         * src/output.c (output_gram): Rely on nritems, not the
2744         0-sentinel.  See below.
2745         Use -1 as separator, not 0.
2746         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
2747         Rely on -1 as separator in yyrhs, instead of 0.
2748         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
2749         twice `Now at end of input', therefore there are two lines less to
2750         expect.
2751
2752 2001-12-27  Akim Demaille  <akim@epita.fr>
2753
2754         * tests/regression.at (Unresolved SR Conflicts):
2755         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
2756         below.
2757
2758 2001-12-27  Akim Demaille  <akim@epita.fr>
2759
2760         * src/LR0.c (new_state): Recognize the final state by the fact it
2761         is reached by eoftoken.
2762         (insert_start_shifting_state, insert_eof_shifting_state)
2763         (insert_accepting_state, augment_automaton): Remove, since now
2764         these states are automatically computed from the initial state.
2765         (generate_states): Adjust.
2766         * src/print.c: When reporting a rule number to the user, substract
2767         1, so that the axiom rule is rule 0, and the first user rule is 1.
2768         * src/reduce.c: Likewise.
2769         * src/print_graph.c (print_core): For the time being, just as for
2770         the report, depend upon --trace-flags to dump the full set of
2771         items.
2772         * src/reader.c (readgram): Once the grammar read, insert the rule
2773         0: `$axiom: START-SYMBOL $'.
2774         * tests/set.at: Adjust: rule 0 is now displayed, and since the
2775         number of the states has changed (the final state is no longer
2776         necessarily the last), catch up.
2777
2778 2001-12-27  Akim Demaille  <akim@epita.fr>
2779
2780         Try to make the use of the eoftoken valid.  Given that its value
2781         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
2782         is used instead of > 0 where appropriate, (ii), depend upon nritems
2783         instead of the 0-sentinel.
2784
2785         * src/gram.h, src/gram.c (nritems): New.
2786         Expected to be duplication of nitems, but for the time being...
2787         * src/reader.c (packgram): Assert nritems and nitems are equal.
2788         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
2789         * src/closure.c (print_closure, print_fderives): Likewise.
2790         * src/gram.c (ritem_print): Likewise.
2791         * src/print.c (print_core, print_grammar): Likewise.
2792         * src/print_graph.c: Likewise.
2793
2794 2001-12-27  Akim Demaille  <akim@epita.fr>
2795
2796         * src/main.c (main): If there are complains after grammar
2797         reductions, then output the report anyway if requested, then die.
2798         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
2799         * src/reader.c (eoftoken): New.
2800         (parse_token_decl): If the token being defined has value `0', it
2801         is the eoftoken.
2802         (packsymbols): No longer hack `tags' to insert `$' by hand.
2803         Be sure to preserve the value of the eoftoken.
2804         (reader): Make sure eoftoken is defined.
2805         Initialize nsyms to 0: now eoftoken is created just like the others.
2806         * src/print.c (print_grammar): Don't special case the eof token.
2807         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
2808         lie anyway, albeit pleasant.
2809         * tests/calc.at: Exercise error messages with eoftoken.
2810         Change the grammar so that empty input is invalid.
2811         Adjust expectations.
2812         When yyungeting, be sure to use a valid yylloc: use last_yylloc.

2814 2001-12-27  Akim Demaille  <akim@epita.fr>
2815
2816         * configure.in: Check the protos of strchr ans strspn.
2817         Replace strchr if needed.
2818         * src/system.h: Provide the protos of strchr, strspn and memchr if
2819         missing.
2820         * lib/strchr.c: New.
2821         * src/reader.c (symbols_save): Use strchr.
2822
2823 2001-12-27  Akim Demaille  <akim@epita.fr>
2824
2825         * src/print.c, src/print_graph.c (escape): New.
2826         Use it to quote the TAGS outputs.
2827         * src/print_graph.c (print_state): Now errors are in red, and
2828         reductions in green.
2829         Prefer high to wide: output the state number on a line of its own.
2830
2831 2001-12-27  Akim Demaille  <akim@epita.fr>
2832
2833         * src/state.h, src/state.c (reductions_new): New.
2834         * src/LR0.c (set_state_table): Let all the states have a
2835         `reductions', even if reduced to 0.
2836         (save_reductions): Adjust.
2837         * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.

2839         * src/output.c (action_row): Adjust.
2840
2841 2001-12-27  Akim Demaille  <akim@epita.fr>
2842
2843         * src/state.h, src/state.c (errs_new, errs_dup): New.
2844         * src/LR0.c (set_state_table): Let all the states have an errs,
2845         even if reduced to 0.
2846         * src/print.c (print_errs, print_reductions): Adjust.
2847         * src/output.c (output_actions, action_row): Adjust.
2848         * src/conflicts.c (resolve_sr_conflict): Adjust.
2849
2850 2001-12-27  Akim Demaille  <akim@epita.fr>
2851
2852         * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
2853
2854 2001-12-27  Akim Demaille  <akim@epita.fr>
2855
2856         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
2857         * src/print.c: here.
2858         (lookaheadset, shiftset): New, used as additional storage by
2859         print_reductions.
2860         (print_results): Adjust.
2861         (print_shifts, print_gotos, print_errs): New, extracted from...
2862         (print_actions): here.
2863         * src/print_graph.c (print_actions): Remove dead code.
2864
2865 2001-12-27  Akim Demaille  <akim@epita.fr>
2866
2867         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
2868         `$n' and `@n'.
2869
2870 2001-12-27  Akim Demaille  <akim@epita.fr>
2871
2872         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
2873         (build_relations): Adjust.
2874
2875 2001-12-27  Akim Demaille  <akim@epita.fr>
2876
2877         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
2878         duplication.
2879
2880 2001-12-27  Akim Demaille  <akim@epita.fr>
2881
2882         * src/reader.c (packgram): Catch nitems overflows.
2883
2884 2001-12-27  Akim Demaille  <akim@epita.fr>
2885
2886         * src/files.c, src/files.h (guard_obstack): Remove.
2887         * src/output.c (output): Adjust.
2888         * src/reader.c (parse_braces): New, factoring...
2889         (copy_action, copy_guard): these two which are renamed as...
2890         (parse_action, parse_guard): these.
2891         As a voluntary consequence, using braces around guards is now
2892         mandatory.
2893
2894 2001-12-27  Akim Demaille  <akim@epita.fr>
2895
2896         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
2897         * src/reader.c (symbol_list): `guard' and `guard_line' are new
2898         members.
2899         (symbol_list_new): Adjust.
2900         (copy_action): action_line is the first line, not the last.
2901         (copy_guard): Just as for actions, store the `action' only, not
2902         the switch/case/break flesh.
2903         Don't parse the user action that might follow the guard, let...
2904         (readgram): do it, i.e., now, there can be an action after a
2905         guard.
2906         In other words the guard is just explicitly optional.
2907         (packgram): Adjust.
2908         * src/output.c (guards_output): New.
2909         (output_parser): Call it when needed.
2910         (output): Also free the guard and attrs obstacks.
2911         * src/files.c, src/files.h (obstack_save): Remove.
2912         (output_files): Remove.
2913         As a result, if one needs the former `.act' file, using an
2914         appropriate skeleton which requires actions and guards is now
2915         required.
2916         * src/main.c (main): Adjust.
2917         * tests/semantic.at: New.
2918         * tests/regression.at: Use `input.y' as input file name.
2919         Avoid 8+3 problems by requiring input.c when the test needs the
2920         parser.
2921
2922 2001-12-27  Akim Demaille  <akim@epita.fr>
2923
2924         * src/reader.c (symbol_list_new): Be sure to initialize all the
2925         fields.
2926
2927 2001-12-27  Akim Demaille  <akim@epita.fr>
2928
2929         All the hacks using a final pseudo state are now useless.
2930
2931         * src/LR0.c (set_state_table): state_table holds exactly nstates.
2932         * src/lalr.c (nLA): New.
2933         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
2934         instead of lookaheadsp from the pseudo state (nstate + 1).
2935
2936 2001-12-27  Akim Demaille  <akim@epita.fr>
2937
2938         * src/output.c (action_row, token_actions): Use a state_t instead
2939         of a integer, and nlookaheads instead of the following state's
2940         lookaheadsp.
2941
2942 2001-12-27  Akim Demaille  <akim@epita.fr>
2943
2944         * src/conflicts.c (log_resolution, flush_shift)

2946         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
2947         (conflicts_print, print_reductions): Use a state_t instead of an
2948         integer when referring to a state.
2949         As much as possible, depend upon nlookaheads, instead of the
2950         `lookaheadsp' member of the following state (since lookaheads of
2951         successive states are successive, the difference between state n + 1
2952         and n served as the number of lookaheads for state n).
2953         * src/lalr.c (add_lookback_edge): Likewise.
2954         * src/print.c (print_core, print_actions, print_state)
2955         (print_results): Likewise.
2956         * src/print_graph.c (print_core, print_actions, print_state)
2957         (print_graph): Likewise.
2958         * src/conflicts.h: Adjust.

2961
2962         * src/bison.hairy: Formatting/comment changes.
2963         ANSIfy.
2964         Remove `register' indications.
2965         Add plenty of `static'.

2967 2001-12-27  Akim Demaille  <akim@epita.fr>
2968
2969         * src/output.c (prepare): Drop the muscle `ntbase' which
2970         duplicates ntokens.
2971         * src/bison.simple: Formatting/comment changes.
2972         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
2973         is an undocumented synonym.
2974
2975 2001-12-22  Akim Demaille  <akim@epita.fr>
2976
2977         * src/output.c (output_table_data): Change the prototype to use
2978         `int' for array ranges: some invocations do pass an int, not a
2979         short.
2980         Reported by Wayne Green.

2988         * tests/regression.at (Web2c): Rename as...
2989         (Web2c Report): this.
2990         (Web2c Actions): New.
2991
2992 2001-12-22  Akim Demaille  <akim@epita.fr>

3001
3002         Some host fail on `assert (!"foo")', which expands to
3003         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
3004         Reported by Nelson Beebee.
3005
3006         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
3007         `#define it_succeeded 0' and `assert (it_succeeded)'.
3008
3009 2001-12-17  Marc Autret  <autret_m@epita.fr>
3010
3011         * src/bison.simple: Don't hard code the skeleton line and filename.
3012         * src/output.c (output_parser): Rename 'line' as 'output_line'.
3013         New line counter 'skeleton_line' (skeleton-line muscle).
3014
3015 2001-12-17  Paul Eggert  <eggert@twinsun.com>
3016
3017         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
3018         YYDEBUG must be defined to a nonzero value.
3019
3020         * src/bison.simple (yytname): Do not assume that the user defines
3021         YYDEBUG to a properly parenthesized expression.
3022
3023 2001-12-17  Akim Demaille  <akim@epita.fr>
3024
3025         * src/state.h (state_t): Rename lookaheads as lookaheadsp.
3026         nlookaheads is a new member.

3035         * src/main.c (main): Don't open/close files, nor invoke lex_free,
3036         let...
3037         * src/reader.c (reader): Do it.
3038
3039 2001-12-17  Akim Demaille  <akim@epita.fr>
3040

3050
3051         * src/output.c (output_obstack): Be static and rename as...

3053         output_obstack.
3054         * src/reader.h (muscle_obstack): Move to...
3055         * src/output.h: here, since it's defined in output.c.
3056
3057 2001-12-17  Akim Demaille  <akim@epita.fr>
3058
3059         * src/output.c (action_row, save_column, default_goto)
3060         (sort_actions, matching_state, pack_vector): Better variable
3061         locality.

3076
3077         * src/output.c (actions_output): Fix. When we use %no-lines,
3078         there is one less line per action.
3079
3080 2001-12-16  Marc Autret  <autret_m@epita.fr>
3081
3082         * src/bison.simple: Remove a useless #line directive.
3083         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
3084         * src/output.c (get_lines_number): New.
3085         (output_parser): Adjust, now takes care about the lines of a
3086         output muscles.
3087         Fix line numbering.
3088         (actions_output): Computes the number of lines taken by actions.
3089         (output_master_parser): Insert new skeleton which is the name of
3090         the output parser file name.
3091
3092 2001-12-15  Marc Autret  <autret_m@epita.fr>

3100 2001-12-15  Akim Demaille  <akim@epita.fr>
3101
3102         Make `make distcheck' work.
3103
3104         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
3105         system.h which uses libgettext.h.
3106
3107 2001-12-15  Akim Demaille  <akim@epita.fr>
3108
3109         * src/nullable.c (set_nullable): Useless rules must be skipped,
3110         otherwise, since we range over their symbols, we might look at a
3111         nonterminal which no longer ``exists'', i.e., it is not counted in
3112         `nvars', hence we overflow our arrays.

3122         * src/reader.c (parse_union_decl): No longer output to
3123         defines_obstack: its content can be found in the `stype' muscle
3124         anyway.
3125         (output_token_translations): Merge into...

3134
3135         * src/reader.c (parse_union_decl): Instead of handling two obstack
3136         simultaneously, use one to define the `stype' muscle, and use the
3137         value of the latter to fill defines_obstack.
3138         (copy_comment): Remove.
3139         (copy_comment2): Work for a single obstack.

3150         Still making progress in separating Bison into (i) input, (ii)
3151         process, (iii) output: now we can directly output the parser file
3152         without using table_obstack at all.
3153
3154         * src/files.c, src/files.h (table_obstack): Bye bye.
3155         (parser_file_name): New.
3156         * src/files.c (compute_output_file_names): Compute it.
3157         * src/output.c (actions_output, output_parser)
3158         (output_master_parser): To a file instead of an obstack.
3159
3160 2001-12-15  Akim Demaille  <akim@epita.fr>
3161
3162         Attach actions to rules, instead of pre-outputting them to
3163         actions_obstack.
3164
3165         * src/gram.h (rule_t): action and action_line are new members.
3166         * src/reader.c (symbol_list): Likewise.
3167         (copy_action): Save the actions within the rule.
3168         (packgram): Save them in rule_table.
3169         * src/output.c (actions_output): New.
3170         (output_parser): Use it on `%%actions'.
3171         (output_rule_data): Don't free rule_table.
3172         (output): Do it.
3173         (prepare): Don't save the `action' muscle.
3174         * src/bison.simple: s/%%action/%%actions/.
3175
3176 2001-12-15  Akim Demaille  <akim@epita.fr>
3177
3178         * src/reader.c (copy_action): When --yacc, don't append a `;'
3179         to the user action: let it fail if lacking.
3180         Suggested by Arnold Robbins and Tom Tromey.
3181
3182 2001-12-14  Akim Demaille  <akim@epita.fr>
3183
3184         * src/lex.c (literalchar): Simply return the char you decoded, non
3185         longer mess around with obstacks and int pointers.
3186         Adjust all callers.
3187
3188 2001-12-14  Akim Demaille  <akim@epita.fr>
3189
3190         * src/lex.c (literalchar): Don't escape the special characters,
3191         just decode them, and keep them as char (before, eol was output as
3192         the 2 char string `\n' etc.).
3193         * src/output.c (output_rule_data): Use quotearg to output the
3194         token strings.
3195
3196 2001-12-13  Paul Eggert  <eggert@twinsun.com>
3197
3198         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
3199         Do not infringe on the global user namespace when using C++.
3200         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
3201         All uses of `fprintf' and `stderr' changed.
3202
3203         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
3204
3205 2001-12-13  Akim Demaille  <akim@epita.fr>
3206
3207         The computation of nullable is broken: it doesn't handle empty
3208         RHS's properly.
3209
3210         * tests/torture.at (GNU AWK Grammar): New.
3211         * tests/sets.at (Nullable): New.
3212         * src/nullable.c (set_nullable): Instead of blindly looping over
3213         `ritems', loop over the rules, and then over their rhs's.
3214
3215         Work around Autotest bugs.
3216
3217         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
3218         frame, because Autotest understand lines starting with a `+' as
3219         traces from the shell.  Then, they are not processed properly.
3220         Admittedly an Autotest bug, but we don't have time to wait for
3221         Autotest to catch up.
3222         * tests/regression.at (Broken Closure): Adjust to the new table
3223         frames.
3224         Move to...
3225         * tests/sets.at: here.
3226
3227 2001-12-13  Akim Demaille  <akim@epita.fr>
3228
3229         * src/closure.c (closure): Use nrules instead of playing tricks
3230         with BITS_PER_WORD.
3231
3232 2001-12-13  Akim Demaille  <akim@epita.fr>
3233
3234         * src/print.c (print_actions): Output the handling of `$' as the
3235         traces do: shifting the token EOF.  Before EOF was treated as a
3236         nonterminal.
3237         * tests/regression.at: Adjust some tests.
3238         * src/print_graph.c (print_core): Complete the set of items via
3239         closure.  The next-to-final and final states are still unsatisfying,
3240         but that's to be addressed elsewhere.
3241         No longer output the rule numbers, but do output the state number.
3242         A single loop for the shifts + gotos is enough, but picked a
3243         distinct color for each.
3244         (print_graph): Initialize and finalize closure.
3245
3246 2001-12-13  Akim Demaille  <akim@epita.fr>
3247
3248         * src/reader.c (readgram): Remove dead code, an strip useless
3249         braces.
3250         (get_type): Remove, unused.
3251
3252 2001-12-12  Akim Demaille  <akim@epita.fr>
3253
3254         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
3255         on that of lib/error.c.
3256
3257 2001-12-12  Akim Demaille  <akim@epita.fr>
3258
3259         Some hosts don't like `/' in includes.
3260
3261         * src/system.h: Include libgettext.h without qualifying the path.
3262         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
3263         $(top_srcdir).
3264
3265 2001-12-11  Marc Autret  <autret_m@epita.fr>
3266
3267         * src/output.c (output_parser): Remove useless muscle.
3268
3269 2001-12-11  Marc Autret  <autret_m@epita.fr>
3270
3271         * src/bison.simple: Remove #line just before %%epilogue. It
3272         is now handled in ...
3273         * src/reader.c (read_additionnal_code): Add the output of a
3274         #line for the epilogue.
3275
3276 2001-12-10  Marc Autret  <autret_m@epita.fr>
3277
3278         * src/reader.c (copy_definition): Re-use CPP-outed code which
3279         replace precedent remove.
3280         * src/bison.simple: Remove #line before %%prologue because
3281         %%input-line is wrong at this time.
3282
3283 2001-12-10  Marc Autret  <autret_m@epita.fr>
3284
3285         * src/reader.c (symbols_output): Clean up.
3286         * src/output.c (output_gram, output): Clean up.
3287
3288 2001-12-10  Akim Demaille  <akim@epita.fr>
3289
3290         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
3291         * src/LR0.c (set_state_table): here.
3292         * src/lalr.c (lalr): Call it.
3293
3294 2001-12-10  Akim Demaille  <akim@epita.fr>
3295
3296         * src/state.h (shifts): Remove the `number' member: shifts are
3297         attached to state, hence no longer need to be labelled with a
3298         state number.
3299
3300 2001-12-10  Akim Demaille  <akim@epita.fr>
3301
3302         Now that states have a complete set of members, the linked list of
3303         shifts is useless: just fill directly the state's shifts member.
3304
3305         * src/state.h (shifts): Remove the `next' member.
3306         * src/LR0.c (first_state, last_state): Remove.
3307         Adjust the callers.
3308         (augment_automaton): Don't look for the shifts that must be added
3309         a shift on EOF: it is those of the state we looked for!  But now,
3310         since shifts are attached, it is no longer needed to looking
3311         merely by its id: its number.
3312
3313 2001-12-10  Akim Demaille  <akim@epita.fr>
3314
3315         * src/LR0.c (augment_automaton): Better variable locality.
3316         Remove an impossible branch: if there is a state corresponding to
3317         the start symbol being shifted, then there is shift for the start
3318         symbol from the initial state.
3319
3320 2001-12-10  Akim Demaille  <akim@epita.fr>
3321
3322         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
3323         only when appropriate: when insert_start_shifting_state' is not
3324         invoked.
3325         * tests/regression.at (Rule Line Numbers): Adjust.
3326
3327 2001-12-10  Akim Demaille  <akim@epita.fr>
3328
3329         * src/LR0.c (augment_automaton): Now that all states have shifts,
3330         merge the two cases addition shifts to the initial state.
3331
3332 2001-12-10  Akim Demaille  <akim@epita.fr>
3333
3334         * src/lalr.c (set_state_table): Move to...
3335         * src/LR0.c: here.
3336         * src/lalr.c (lalr): Don't call it...
3337         * src/LR0.c (generate_states): do it.
3338         * src/LR0.h (first_state): Remove, only the table is used.
3339
3340 2001-12-10  Akim Demaille  <akim@epita.fr>
3341
3342         * src/LR0.h (first_shift, first_reduction): Remove.
3343         * src/lalr.c: Don't use first_shift: find shifts through the
3344         states.
3345
3346 2001-12-10  Akim Demaille  <akim@epita.fr>
3347
3348         * src/LR0.c: Attach shifts to states as soon as they are
3349         computed.
3350         * src/lalr.c (set_state_table): Instead of assigning shifts to
3351         state, just assert that the mapping was properly done.
3352
3353 2001-12-10  Akim Demaille  <akim@epita.fr>
3354
3355         * src/LR0.c (insert_start_shift): Rename as...
3356         (insert_start_shifting_state): this.
3357         (insert_eof_shifting_state, insert_accepting_state): New.
3358         (augment_automaton): Adjust.
3359         Better locality of the variables.
3360         When looking if the start_symbol is shifted from the initial
3361         state, using `while (... symbol != start_symbol ...)' sounds
3362         better than `while (... symbol < start_symbol ...)': If fail
3363         to see how the order between symbols could be relevant!
3364
3365 2001-12-10  Akim Demaille  <akim@epita.fr>
3366
3367         * src/getargs.h: Don't declare `spec_name_prefix' and
3368         `spec_file_prefix', declared by src/files.h.
3369         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
3370         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
3371         * src/output.c (prepare): Adjust.
3372         * src/reader.c (symbols_output): Likewise.
3373         * src/vmsgetargs.c: Vaguely adjust, but who cares?
3374
3375 2001-12-10  Akim Demaille  <akim@epita.fr>
3376
3377         * src/muscle_tab.c (muscle_init): NULL is a better default than
3378         `"0"'.
3379
3380 2001-12-10  Akim Demaille  <akim@epita.fr>
3381
3382         * src/reader.c (reader): Calling symbols_output once is enough.
3383
3384 2001-12-10  Akim Demaille  <akim@epita.fr>
3385
3386         Now that states have a complete set of members, the linked list of
3387         reductions is useless: just fill directly the state's reductions
3388         member.
3389
3390         * src/state.h (struct reductions): Remove member `number' and
3391         `next'.
3392         * src/LR0.c (first_reduction, last_reduction): Remove.
3393         (save_reductions): Don't link the new reductions, store them in
3394         this_state.
3395         * src/lalr.c (set_state_table): No need to attach reductions to
3396         states, it's already done.
3397         * src/output.c (output_actions): No longer free the shifts, then
3398         the reductions, then the states: free all the states and their
3399         members.
3400
3401 2001-12-10  Akim Demaille  <akim@epita.fr>
3402
3403         * src/options.c (OPTN, DRTV, BOTH): New.
3404         (option_table): Use them.
3405
3406         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
3407         the job of system.h.
3408         * src/options.c: Don't include stdio.h and xalloc.h for the same
3409         reasons.
3410
3411 2001-12-10  Akim Demaille  <akim@epita.fr>
3412
3413         * src/output.c (output, prepare): Make sure the values of the
3414         muscles `action' and `prologue' are 0-terminated.
3415
3416 2001-12-10  Akim Demaille  <akim@epita.fr>
3417
3418         Clean up GCC warnings.
3419
3420         * src/reader.c (copy_action): `buf' is not used.
3421         (parse_skel_decl): Be static.
3422         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
3423         * src/options.h (create_long_option_table): Have a real prototype.
3424         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
3425         (hash_delete_at): Return const void *.
3426         Adjust casts to preserve the const.
3427
3428 2001-12-10  Akim Demaille  <akim@epita.fr>
3429
3430         * configure.in: Require 2.52g.
3431         M4 is not needed, but AUTOM4TE is.
3432         * m4/m4.m4: Remove.
3433         * tests/Makefile.am: Adjust.
3434
3435 2001-12-10  Akim Demaille  <akim@epita.fr>
3436
3437         One structure for states is enough, even though theoretically
3438         there are LR(0) states and LALR(1) states.
3439
3440         * src/lalr.h (state_t): Remove.
3441         (state_table): Be state_t **, not state_t *.
3442         * src/state.h (core, CORE_ALLOC): Rename as...
3443         (state_t, STATE_ALLOC): this.
3444         Add the LALR(1) members: shifts, reductions, errs.
3445         * src/LR0.c (state_table): Rename as...
3446         (state_hash): this, to avoid name clashes with the global
3447         `state_table'.
3448         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
3449         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
3450
3451 2001-12-10  Akim Demaille  <akim@epita.fr>
3452
3453         Bison dumps core on bash.y.
3454         Reported by Pascal Bart.
3455
3456         * src/warshall.c (bitmatrix_print): New.
3457         (TC): Use it.
3458         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
3459         j must be the outer loop.
3460         * tests/regression.at (Broken Closure): New.
3461
3462 2001-12-05  Akim Demaille  <akim@epita.fr>
3463
3464         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
3465         its argument.
3466         Reported by Peter Hámorský.
3467
3468 2001-12-05  Akim Demaille  <akim@epita.fr>
3469
3470         * src/conflicts.c (err_table): Remove.
3471         (resolve_sr_conflict): Adjust.
3472         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
3473         Rename as...
3474         (state_t.reductions, state_t.shifts): this.
3475
3476 2001-12-05  Akim Demaille  <akim@epita.fr>
3477
3478         * src/reduce.c (reduce_grammar_tables): No longer disable the
3479         removal of useless rules via CPP but via `if (0)', so that the
3480         compiler still check the code is valid.
3481         For instance, it should have noticed `rline' no longer exists: use
3482         the `line' member of rule_t.
3483         * src/gram.c (dummy, rline): Remove, unused.
3484
3485 2001-12-05  Akim Demaille  <akim@epita.fr>
3486
3487         * src/output.c (pack_vector): Use assert, not berror.
3488         * src/main.c (berror): Remove, unused.
3489
3490 2001-12-05  Akim Demaille  <akim@epita.fr>
3491
3492         New experimental feature: if --verbose --trace output all the
3493         items of a state, not only its kernel.
3494
3495         * src/print.c (print_core): If `trace_flag', then invoke closure
3496         before outputting the items of the state (print_core is no longer
3497         a correct name them).
3498         (print_results): Invoke new_closure/free_closure if needed.
3499
3500 2001-12-05  Akim Demaille  <akim@epita.fr>
3501
3502         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
3503         * src/closure.c, src/closure.h (itemsetsize): Rename as...
3504         (nitemset): for consistency with the rest of the project.
3505
3506 2001-12-05  Akim Demaille  <akim@epita.fr>
3507
3508         * src/closure.c (print_closure): Improve.
3509         (closure): Use it for printing input and output.
3510
3511 2001-12-05  Akim Demaille  <akim@epita.fr>
3512
3513         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
3514         indexed by nonterminals.
3515
3516 2001-12-05  Akim Demaille  <akim@epita.fr>
3517
3518         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
3519         what it was!).
3520         * src/warshall.h: Remove accidental duplication of the content.
3521
3522 2001-12-05  Akim Demaille  <akim@epita.fr>
3523
3524         * src/closure.c (set_fderives): De-obfuscate.
3525
3526 2001-12-05  Akim Demaille  <akim@epita.fr>
3527

3529
3530 2001-12-05  Akim Demaille  <akim@epita.fr>
3531
3532         * src/closure.c (set_firsts): De-obfuscate.
3533
3534 2001-12-05  Akim Demaille  <akim@epita.fr>
3535
3536         * src/output.c (action_row): De-obfuscate
3537         using the good o' techniques: arrays not pointers, variable
3538         locality, BITISSET, RESETBIT etc.
3539
3540 2001-12-05  Akim Demaille  <akim@epita.fr>
3541
3542         Pessimize the code to simplify it: from now on, all the states
3543         have a valid SHIFTS, which NSHIFTS is possibly 0.
3544
3545         * src/LR0.c (shifts_new): Be global and move to..
3546         * src/state.c, src/state.h: here.
3547         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
3548         * src/print_graph: Adjust.
3549
3550 2001-12-05  Akim Demaille  <akim@epita.fr>
3551
3552         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
3553         * src/conflicts.c: Use it.
3554         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
3555         incorrectly ``simplified''.
3556
3557 2001-12-05  Akim Demaille  <akim@epita.fr>
3558
3559         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
3560         using the good o' techniques: arrays not pointers, variable
3561         locality, BITISSET, RESETBIT etc.
3562
3563 2001-12-05  Akim Demaille  <akim@epita.fr>
3564
3565         * src/state.h (SHIFT_SYMBOL): New.
3566         * src/conflicts.c: Use it to deobfuscate.
3567
3568 2001-12-05  Akim Demaille  <akim@epita.fr>
3569
3570         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
3571         (print_reductions): De-obfuscate using the good o' techniques:
3572         arrays not pointers, variable locality, BITISSET.
3573
3574 2001-12-05  Akim Demaille  <akim@epita.fr>
3575
3576         * src/conflicts.c (print_reductions): Arrays, not pointers.
3577         Use BITISSET.
3578
3579 2001-12-05  Akim Demaille  <akim@epita.fr>
3580
3581         * src/conflicts.c (print_reductions): Pessimize, but clarify.
3582
3583 2001-12-05  Akim Demaille  <akim@epita.fr>
3584
3585         * src/conflicts.c (print_reductions): Improve variable locality.
3586
3587 2001-12-05  Akim Demaille  <akim@epita.fr>
3588
3589         * src/conflicts.c (print_reductions): Pessimize, but clarify.
3590
3591 2001-12-05  Akim Demaille  <akim@epita.fr>
3592
3593         * src/conflicts.c (print_reductions): Improve variable locality.
3594
3595 2001-12-05  Akim Demaille  <akim@epita.fr>
3596
3597         * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
3598         * src/lalr.c: Use them.
3599
3600 2001-12-05  Akim Demaille  <akim@epita.fr>
3601
3602         * src/LR0.c (augment_automaton): Formatting changes.
3603         Better variable locality.
3604
3605 2001-12-05  Akim Demaille  <akim@epita.fr>
3606
3607         * src/lalr.c (matrix_print): New.
3608         (transpose): Use it.
3609         Use arrays instead of pointers.
3610
3611 2001-12-05  Akim Demaille  <akim@epita.fr>
3612
3613         * src/lalr.c (maxrhs): Move to...
3614         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
3615         * src/lalr.c (build_relations): Adjust.
3616
3617 2001-12-05  Akim Demaille  <akim@epita.fr>
3618
3619         * src/lalr.c (transpose): Free the memory allocated to the
3620         argument, as it is replaced by the results by the unique caller.
3621         (build_relations): Merely invoke transpose: it handles the memory
3622         deallocation.
3623         Improve variable locality.
3624         Avoid variables used as mere abbreviations.
3625         (compute_lookaheads): Use arrays instead of pointers.
3626
3627 2001-12-05  Akim Demaille  <akim@epita.fr>
3628
3629         * src/lalr.c (initialize_F): Improve variable locality.
3630         Avoid variables used as mere abbreviations.
3631
3632 2001-12-05  Akim Demaille  <akim@epita.fr>
3633
3634         * src/derives.c (print_derives): Display the ruleno.
3635         * src/lalr.c (initialize_F, transpose): Better variable locality
3636         to improve readability.
3637         Avoid variables used as mere abbreviations.
3638
3639 2001-12-05  Akim Demaille  <akim@epita.fr>
3640
3641         * src/lalr.c (traverse): Use arrays instead of pointers.
3642
3643 2001-12-05  Akim Demaille  <akim@epita.fr>
3644
3645         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
3646         the handling of squeue.
3647         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
3648
3649 2001-12-05  Akim Demaille  <akim@epita.fr>
3650
3651         Because useless nonterminals are now kept alive (instead of being
3652         `destroyed'), we now sometimes examine them, and store information
3653         related to them.  Hence we need to know their number, and adjust
3654         memory allocations.
3655
3656         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
3657         static.
3658         * src/LR0.c (allocate_itemsets): The memory allocated to
3659         `symbol_count' was used for two different purpose: once to count
3660         the number of occurrences of each symbol, and later reassigned to
3661         `shift_symbol', containing the symbol that can be shifted from a
3662         given state.
3663         Deobfuscate, i.e., allocate, use and free `symbol_count' here
3664         only, and...
3665         (new_itemsets): Allocate `shift_symbol' here.
3666         (allocate_itemsets): symbol_count includes useless nonterminals.
3667         Make room for them.
3668         (free_storage): Use `free', not `XFREE', for pointers that cannot
3669         be null.
3670
3671 2001-12-05  Akim Demaille  <akim@epita.fr>
3672
3673         * src/nullable.c (set_nullable): Deobfuscate the handling of
3674         ritem.
3675         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
3676
3677 2001-12-05  Akim Demaille  <akim@epita.fr>
3678
3679         * src/gram.c, src/gram.h (ritem_print): New.
3680         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
3681         (This useless function was defined only to work around VMS linkers
3682         that can't handle compilation units with variables only).
3683         * src/reduce.c (dump_grammar): Use it to trace the construction of
3684         ritem.
3685
3686 2001-12-04  Paul Eggert  <eggert@twinsun.com>
3687
3688         * src/bison.simple (union yyalloc): Change member names
3689         to be the same as the stack names.
3690         (yyparse): yyptr is now union yyalloc *, not char *.
3691         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
3692         and may generate better code on some machines.
3693         (yystpcpy): Use prototype if __STDC__ is defined, not just
3694         if __cplusplus is defined.
3695
3696 2001-11-30  Akim Demaille  <akim@epita.fr>
3697
3698         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
3699         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
3700         Gettext doesn't compile cleanly, and dies with -Werror.
3701         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
3702         Include WARNING_CFLAGS here.
3703         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
3704         before being defined.
3705
3706 2001-11-27  Paul Eggert  <eggert@twinsun.com>
3707
3708         * lib/quotearg.h (quotearg_n, quotearg_n_style):
3709         First arg is int, not unsigned.
3710         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
3711         (SIZE_MAX, UINT_MAX): New macros.
3712         (quotearg_n_options): Abort if N is negative.
3713         Avoid overflow check on hosts where size_t is 64 bits and int
3714         is 32 bits, as overflow is impossible there.
3715         Fix off-by-one typo that caused unnecessary reallocation.
3716
3717 2001-11-29  Paul Eggert  <eggert@twinsun.com>
3718
3719         Name space cleanup in generated parser.
3720
3721         * doc/bison.texinfo (Bison Parser): Discuss system headers
3722         and their effect on the user name space.
3723
3724         * src/bison.simple:
3725         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
3726         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
3727         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
3728
3729         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
3730         on user names when possible.
3731
3732         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
3733         Simplify test for whather <alloca.h> exists.
3734
3735         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
3736
3737         (<stdio.h>): Include if YYDEBUG.
3738
3739         (yymemcpy): Renamed from __yy_memcpy.  Do not define unless
3740         ! defined (yyoverflow) && ! defined (yymemcpy).
3741
3742         (yymemcpy, yyparse): Rename local variables as needed so that
3743         they all begin with 'yy'.
3744
3745         (yystrlen, yystpcpy): New functions.
3746
3747         (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
3748         All uses changed.
3749
3750         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
3751         instead of relying on string.h functions.  Use YYSTACK_ALLOC
3752         and YYSTACK_FREE instead of malloc and free.
3753
3754 2001-11-30  Akim Demaille  <akim@epita.fr>
3755
3756         * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
3757         before their first uses.
3758         (YYBISON, YYPURE): Move to the top of the output.
3759
3760 2001-11-30  Akim Demaille  <akim@epita.fr>
3761
3762         * tests/reduce.at (Useless Nonterminals): Fix.
3763
3764 2001-11-30  Akim Demaille  <akim@epita.fr>
3765
3766         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
3767         if body instead of `;' to pacify GCC's warnings.
3768
3769 2001-11-30  Akim Demaille  <akim@epita.fr>
3770
3771         Instead of mapping the LHS of unused rules to -1, keep the LHS
3772         valid, but flag the rules as invalid.
3773
3774         * src/gram.h (rule_t): `useful' is a new member.
3775         * src/print.c (print_grammar): Adjust.
3776         * src/derives.c (set_derives): Likewise.
3777         * src/reader.c (packgram, reduce_output): Likewise.
3778         * src/reduce.c (reduce_grammar_tables): Likewise.
3779         * tests/reduce.at (Underivable Rules, Useless Rules): New.
3780
3781 2001-11-30  Akim Demaille  <akim@epita.fr>
3782
3783         * src/reduce.c (reduce_output): Formatting changes.
3784         * src/print.c (print_results, print_grammar): Likewise.
3785         * tests/regression.at (Rule Line Numbers)
3786         (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
3787
3788 2001-11-30  Akim Demaille  <akim@epita.fr>
3789
3790         * src/reduce.c (nonterminals_reduce): Instead of throwing away
3791         useless nonterminals, move them at the end of the symbol arrays.
3792         (reduce_output): Adjust.
3793         * tests/reduce.at (Useless Nonterminals): Adjust.
3794
3795 2001-11-30  Akim Demaille  <akim@epita.fr>
3796
3797         * src/reduce.c: Various comment/formatting changes.
3798         (nonterminals_reduce): New, extracted from...
3799         (reduce_grammar_tables): here.
3800         (reduce_grammar): Call nonterminals_reduce.
3801
3802 2001-11-29  Paul Eggert  <eggert@twinsun.com>
3803
3804         * src/bison.simple (YYSTACK_REALLOC): Remove.
3805         (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
3806         (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
3807         New macros.
3808         (union yyalloc): New type.
3809         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
3810         an arbitrary restriction on hosts where size_t is wider than int.
3811
3812         (yyparse): Don't dump core if alloca or malloc fails; instead, report
3813         a parser stack overflow.  Allocate just one block of memory for all
3814         three stacks, instead of allocating three blocks; this typically is
3815         faster and reduces fragmentation.
3816
3817         Do not limit the number of items in the stack to a value that fits
3818         in 'int', as this is an arbitrary limit on hosts with 64-bit
3819         size_t and 32-bit int.
3820
3821 2001-11-29  Marc Autret  <autret_m@epita.fr>
3822
3823         * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
3824         of defining YYERROR_VERBOSE.
3825         [AT_DATA]: $4 is now out of C declarations in the prologue.
3826
3827 2001-11-28  Marc Autret  <autret_m@epita.fr>
3828
3829         * src/reader.c (parse_dquoted_param): New.
3830         (parse_skel_decl): Use it.
3831         * src/lex.h: Add its prototype.
3832         * src/lex.c (literalchar): Become not static.
3833
3834 2001-11-28  Marc Autret  <autret_m@epita.fr>
3835
3836         * src/output.h: And put its extern declaration here.
3837         * src/output.c (error_verbose): Define here.
3838         (prepare): Echo name modification.
3839         * src/getargs.h: Clean its extern declaration.
3840         * src/getargs.c (error_verbose_flag): Remove.
3841         (getargs): Remove case 'e'.
3842         * src/options.c (option_table): 'error-verbose' is now seen as simple
3843         percent option.
3844         Include output.h.
3845
3846         * src/reader.c (read_declarations): Remove case tok_include.
3847         (parse_include_decl): Remove.
3848         * src/lex.h (token_t): Remove tok_include.
3849         * src/options.c (option_table): 'include' is now a simple command line
3850         option.
3851
3852 2001-11-28  Marc Autret  <autret_m@epita.fr>
3853
3854         * src/bison.simple: Adjust muscle names.
3855         * src/muscle_tab.c (muscle_init): Also rename the muscles.
3856         * src/output.c (prepare): s/_/-/ for the muscles names.
3857         (output_parser): When scanning for a muscle, allow '-' instead of '_'.
3858
3859 2001-11-28  Marc Autret  <autret_m@epita.fr>

4247         * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
4248         now the tests are run in private dirs, therefore AC_CLEANUP and
4249         family can be simplified to 0-ary.
4250         * tests/atlocal.in: Now that we run `elsewhere' than in tests/,

5643 2001-01-19  Akim Demaille  <akim@epita.fr>
5644
5645         Get rid of the ad hoc handling of token_buffer in the scanner: use
5646         the obstacks.
5647
5648         * src/lex.c (token_obstack): New.
5649         (init_lex): Initialize it.  No longer call...
5650         (grow_token_buffer): this.  Remove it.
5651         Adjust all the places which used it to use the obstack.
5652
5653 2001-01-19  Akim Demaille  <akim@epita.fr>
5654
5655         * src/lex.h: Rename all the tokens:
5656         s/\bENDFILE\b/tok_eof/g;
5657         s/\bIDENTIFIER\b/tok_identifier/g;
5658         etc.
5659         Let them be enums, not #define, to ease debugging.
5660         Adjust all the code.
5661
5662 2001-01-18  Akim Demaille  <akim@epita.fr>

5666
5667 2001-01-18  Akim Demaille  <akim@epita.fr>
5668
5669         Since we now use obstacks, more % directives can be enabled.
5670
5671         * src/lex.c (percent_table): Also accept `%yacc',
5672         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
5673         `%debug'.
5674         Handle the actions for `%semantic_parser' and `%pure_parser' here,
5675         instead of returning a token.
5676         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
5677         * src/reader.c (read_declarations): Adjust.
5678         * src/files.c (open_files): Don't call `compute_base_names', don't
5679         compute `attrsfile' since they depend upon data which might be
5680         *in* the input file now.
5681         (output_files): Do it here.
5682         * src/output.c (output_headers): Document the fact that this patch
5683         introduces a guaranteed SEGV for semantic parsers.
5684         * doc/bison.texinfo: Document them.
5685         * tests/suite.at: Exercise these %options.
5686
5687 2000-12-20  Akim Demaille  <akim@epita.fr>
5688

5708         FILE * parameters.
5709
5710 2000-12-20  Akim Demaille  <akim@epita.fr>
5711
5712         * src/files.c (open_files): Actually the `.output' file is based
5713         on the short_base_name, not base_name.
5714         * tests/suite.at (Checking output file names): Adjust.
5715
5716 2000-12-20  Akim Demaille  <akim@epita.fr>

5742         (stringappend): Be just like strcat but allocate.
5743         (base_names): Eve out from open_files.
5744         Try to simplify the rather hairy computation of base_name and
5745         short_base_name.

5747         * tests/suite.at (Checking output file names): New test.

5764
5765 2000-12-19  Akim Demaille  <akim@epita.fr>
5766
5767         Let the handling of the skeleton files be local to the procedures
5768         that use it.
5769
5770         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
5771         longer static.

5784
5785 2000-12-19  Akim Demaille  <akim@epita.fr>
5786
5787         * src/files.c (open_files): Yipee!  We no longer need all the code
5788         looking for `/tmp' since we have no tmp file.
5789
5790 2000-12-19  Akim Demaille  <akim@epita.fr>

5819         * lib/obstack.h: Formatting changes.
5820         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
5821         prevents type checking.
5822         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
5823         cast the value to (void *): assigning a `foo *' to a `void *'
5824         variable is valid.
5825         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
5826         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

5861
5862 2000-11-07  Akim Demaille  <akim@epita.fr>
5863
5864         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
5865         Merge in a single CPP if/else.

5870         * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second

5874         `address' for consistency.  Qualify it `const'.

5906         * src/main.c (main): Don't use `atexit' to register `done', since
5907         it no longer has to remove tmp files, just call `output_files'
5908         when there are no errors.
5909
5910 2000-11-02  Akim Demaille  <akim@epita.fr>

6013         When a literal string is used to define two different tokens,
6014         `bison -v' segfaults.
6015         Reported by Piotr Gackiewicz, and fixed by Neil Booth.

6029
6030         * bison.s1 (yyparse): Assign the default value
6031         unconditionally, to avoid a GCC warning and make the parser a
6032         tad smaller.

6045
6046         The location tracking mechanism is precious for parse error
6047         messages.  Nevertheless, it is enabled only when `@n' is used in
6048         the grammar, which is a different issue (you can use it in error
6049         message, but not in the grammar per se).  Therefore, there should
6050         be another means to enable it.
6051
6052         * src/getargs.c (getargs): Support `--locations'.
6053         (usage): Report it.
6054         * src/getargs.h (locationsflag): Export it.
6055         * src/lex.c (percent_table): Support `%locations'.
6056         * src/reader.c (yylsp_needed): Remove this variable, now replaced
6057         with `locationsflag'.
6058         * doc/bison.texinfo: Document `--locations' and `%locations'.
6059         Sort the options.
6060         * tests/calc.m4: Test it.
6061
6062         For regularity of the names, replace each
6063         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
6064         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
6065         In addition replace each `flag' with `_flag'.
6066
6067 2000-10-02  Akim Demaille  <akim@epita.fr>
6068
6069         Also test parse error messages, including with YYERROR_VERBOSE.
6070
6071         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
6072         associative).
6073         Use it to check the computations.
6074         Use it to check `nonassoc' is honored.
6075         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
6076         `--yyerror-verbose'.
6077         (_AT_CHECK_CALC): Adjust to this option.
6078         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
6079
6080 2000-10-02  Akim Demaille  <akim@epita.fr>
6081
6082         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
6083         the latter demonstrates a flaw in the handling of non debugging
6084         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
6085         was used in order to simplify:
6086
6087         #if YYDEBUG
6088         if (yydebug)
6089         {
6090         ...
6091         }
6092         #endif
6093
6094         into
6095
6096         if (yydebug)
6097         {
6098         ...
6099         }
6100
6101         unfortunately this leads to a CPP conflict when
6102         `--name-prefix=foo' is used since it produces `#define yydebug
6103         foodebug'.
6104
6105         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
6106         (YYDPRINTF): New macro.
6107         Spread its use.
6108         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
6109         the bison options.
6110         Also test `--verbose', `--defines' and `--name-prefix'.
6111
6112 2000-10-02  Akim Demaille  <akim@epita.fr>
6113
6114         Improve the readability of the produced parsers.
6115
6116         * src/bison.s1: Formatting changes.
6117         Improve the comment related to the `$' mark.
6118         (yydefault): Don't fall through to `yyresume': `goto' there.
6119         * src/output.c (output_parser): When the `$' is met, skip the end
6120         of its line.
6121         New variable, `number_of_dollar_signs', to check there's exactly
6122         one `$' in the parser skeleton.

6124 2000-10-02  Akim Demaille  <akim@epita.fr>

6128         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
6129         instead of strlen + xmalloc + strcpy.
6130         * src/symtab.c (copys): Remove, use xstrdup instead.
6131
6132 2000-10-02  Akim Demaille  <akim@epita.fr>
6133
6134         * src/gram.h (associativity): New enum type which replaces the
6135         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
6136         `right_assoc', `left_assoc' and `non_assoc'.
6137         Adjust all dependencies.
6138         * src/reader.c: Formatting changes.
6139         (LTYPESTR): Don't define it, use it as a literal in
6140         `reader_output_yylsp'.
6141         * src/symtab.h (symbol_class): New enum type which replaces the
6142         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
6143         `sunknown', `stoken and `snterm'.

6146

6150
6151 2000-10-02  Akim Demaille  <akim@epita.fr>
6152
6153         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
6154         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
6155         difficult and introduced a lot of core dump.  It turns out that
6156         Bison used an implementation of `xmalloc' based on `calloc', and
6157         at various places it does depend upon the initialization to 0.  I
6158         have not tried to isolate the pertinent places, and all the former
6159         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
6160         someone should address this issue.
6161
6162         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
6163         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

6262
6263         `user_toknums' is output as a `short[]' in `output.c', while it is
6264         defined as a `int[]' in `reader.c'.  For consistency with the
6265         other output tables, `user_toknums' is now defined as a table of

6310         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the

6475
6476 2000-03-17  Akim Demaille  <akim@epita.fr>
6477
6478         On syntax errors, report the token on which we choked.

6500         copy_comment.  Removed now unused `match', `ended',
6501         `cplus_comment'.
6502         (copy_comment, copy_string): Moved, to be visible from
6503         copy_definition.
6504

6529
6530         Change the handling of @s so that they behave exactly like $s.
6531         There is now a pseudo variable @$ (readble and writable), location
6532         of the lhs of the rule (by default ranging from the location of
6533         the first symbol of the rhs, to the location of the last symbol,
6534         or, if the rhs is empty, YYLLOC).
6535
6536         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
6537         yyval.
6538         (yyparse): When providing a default semantic action, provide a
6539         default location action.
6540         (after the $): No longer change `*YYLSP', just stack YYLOC the
6541         same way you stack YYVAL.
6542         * src/reader.c (read_declarations): Use warns.
6543         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
6544         (copy_action, case '@'): Likewise.
6545         Use a standard error message, to save useless work from
6546         translators.
6547
6548 2000-03-17  Akim Demaille  <akim@epita.fr>
6549

6567
6568         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
6569         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
6570         One `#if YYDEBUG' remains, since it uses variables which are
6571         defined only if `YYDEBUG != 0'.
6572
6573 2000-03-16  Akim Demaille  <akim@epita.fr>

6605         the proper line number and file name.
6606         (DEFS): Propagate the location of bison library files and of the
6607         locale files.
6608         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
6609         builddir.
6610         * acinclude.m4: Remove, replaced by the directory m4.
6611         * m4/Makefile.am (EXTRA_DIST): New variable.
6612         * m4/gettext.m4: New file, from the fileutils.
