 763         * src/reader.c (output_token_defines): Suppress call to `raw_flag'.
 764         * tests/calc.at: Suppress test with option `--raw'.
 765
 766 2001-07-14  Akim Demaille  <akim@epita.fr>
 767
 768         * config/: New.
 769         * configure.in: Require Autoconf 2.50.
 770         Update to gettext 0.10.38.
 771
 772 2001-03-16  Akim Demaille  <akim@epita.fr>
 773
 774         * doc/bison.texinfo: ANSIfy the examples.
 775
 776 2001-03-16  Akim Demaille  <akim@epita.fr>
 777
 778         * getargs.c (skeleton): New variable.
 779         (longopts): --skeleton is a new option.
 780         (shortopts, getargs): -S is a new option.
 781         * getargs.h: Declare skeleton.
 782         * output.c (output_parser): Use it.
 783
 784 2001-03-16  Akim Demaille  <akim@epita.fr>
 785
 786         * m4/strerror_r.m4: New.

 793
 794 2001-02-21  Akim Demaille  <akim@epita.fr>
 795
 796         * src/reader.c (gensym): `gensym_count' is your own.
 797         Use a static buf to create the symbol name, as token_buffer is no
 798         longer a buffer.
 799
 800 2001-02-08  Akim Demaille  <akim@epita.fr>
 801
 802         * src/conflicts.c (conflict_report): Be sure not to append to res
 803         between two calls, which could happen if both first sprintf were
 804         skipped, but not the first cp += strlen.
 805
 806 2001-02-08  Akim Demaille  <akim@epita.fr>
 807
 808         * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
 809         New, from fileutils 4.0.37.
 810         * configure.in: Require Autoconf 2.49c.  I took some time before
 811         making this decision.  This is the only way out for portability
 812         issues in Bison, it would mean way too much duplicate effort to
 813         import in Bison features implemented in 2.49c since 2.13.
 814         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
 815

 822
 823         Get rid of the ad hoc handling of token_buffer in the scanner: use
 824         the obstacks.
 825
 826         * src/lex.c (token_obstack): New.
 827         (init_lex): Initialize it.  No longer call...
 828         (grow_token_buffer): this.  Remove it.
 829         Adjust all the places which used it to use the obstack.
 830
 831 2001-01-19  Akim Demaille  <akim@epita.fr>
 832
 833         * src/lex.h: Rename all the tokens:
 834         s/\bENDFILE\b/tok_eof/g;
 835         s/\bIDENTIFIER\b/tok_identifier/g;
 836         etc.
 837         Let them be enums, not #define, to ease debugging.
 838         Adjust all the code.
 839
 840 2001-01-18  Akim Demaille  <akim@epita.fr>
 841
 842         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
 843         * src/lex.c (maxtoken, grow_token_buffer): Static.
 844
 845 2001-01-18  Akim Demaille  <akim@epita.fr>
 846
 847         Since we now use obstacks, more % directives can be enabled.
 848
 849         * src/lex.c (percent_table): Also accept `%yacc',
 850         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
 851         `%debug'.
 852         Handle the actions for `%semantic_parser' and `%pure_parser' here,
 853         instead of returning a token.
 854         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
 855         * src/reader.c (read_declarations): Adjust.
 856         * src/files.c (open_files): Don't call `compute_base_names', don't
 857         compute `attrsfile' since they depend upon data which might be
 858         *in* the input file now.
 859         (output_files): Do it here.
 860         * src/output.c (output_headers): Document the fact that this patch
 861         introduces a guaranteed SEGV for semantic parsers.
 862         * doc/bison.texinfo: Document them.
 863         * tests/suite.at: Exercise these %options.
 864
 865 2000-12-20  Akim Demaille  <akim@epita.fr>
 866
 867         Also handle the output file (--verbose) with obstacks.

 871         Adjust all dependencies.
 872         * src/conflicts.c: Return a string.
 873         * src/system.h (obstack_grow_string): Rename as...
 874         (obstack_sgrow): this.  Be ready to work with non literals.
 875         (obstack_fgrow4): New.
 876
 877 2000-12-20  Akim Demaille  <akim@epita.fr>
 878
 879         * src/files.c (open_files): Fix the computation of short_base_name
 880         in the case of `-o foo.tab.c'.
 881
 882 2000-12-20  Akim Demaille  <akim@epita.fr>
 883
 884         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
 885         (copy_dollar): Now that everything uses obstacks, get rid of the
 886         FILE * parameters.
 887
 888 2000-12-20  Akim Demaille  <akim@epita.fr>
 889
 890         * src/files.c (open_files): Actually the `.output' file is based
 891         on the short_base_name, not base_name.
 892         * tests/suite.at (Checking output file names): Adjust.
 893
 894 2000-12-20  Akim Demaille  <akim@epita.fr>

 897         * src/bison.simple: this.
 898         * src/Makefile.am: Use pkgdata instead of data.
 899
 900 2000-12-20  Akim Demaille  <akim@epita.fr>
 901
 902         * src/files.c (guard_obstack): New.

 919         * src/files.c (strsuffix): New.
 920         (stringappend): Be just like strcat but allocate.
 921         (base_names): Eve out from open_files.
 922         Try to simplify the rather hairy computation of base_name and
 923         short_base_name.
 924         (open_files): Use it.
 925         * tests/suite.at (Checking output file names): New test.
 926
 927 2000-12-19  Akim Demaille  <akim@epita.fr>

 930         (obstack_grow_string): this.
 931         * src/output.c (output_parser): Recognize `%% actions' instead of
 932         `$'.

 934         * src/bison.hairy: Likewise.
 935
 936 2000-12-19  Akim Demaille  <akim@epita.fr>
 937
 938         * src/output.c (output_parser): Compute the `#line' lines when
 939         there are.
 940         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
 941         Suggested by Hans Aberg.
 942
 943 2000-12-19  Akim Demaille  <akim@epita.fr>
 944
 945         Let the handling of the skeleton files be local to the procedures
 946         that use it.
 947
 948         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
 949         longer static.
 950         (fparser, open_extra_files): Remove.
 951         (open_files, output_files): Don't take care of fparser.

 963 2000-12-19  Akim Demaille  <akim@epita.fr>
 964
 965         * src/files.c (open_files): Yipee!  We no longer need all the code
 966         looking for `/tmp' since we have no tmp file.
 967
 968 2000-12-19  Akim Demaille  <akim@epita.fr>
 969
 970         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

 996
 997         * lib/obstack.h: Formatting changes.
 998         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
 999         prevents type checking.
1000         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
1001         cast the value to (void *): assigning a `foo *' to a `void *'
1002         variable is valid.
1003         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
1004         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to
1005         append characters.
1006
1007 2000-11-17  Akim Demaille  <akim@epita.fr>
1008

1020
1021         * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New

1039
1040 2000-11-07  Akim Demaille  <akim@epita.fr>
1041
1042         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
1043         Merge in a single CPP if/else.

1052         `address' for consistency.  Qualify it `const'.
1053         * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
1054         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
1055         `const' their input argument (`data' or `address').
1056         Adjust the corresponding macros to include `const' in casts.
1057
1058 2000-11-03  Akim Demaille  <akim@epita.fr>
1059
1060         * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.

1062         Adjust dependencies.
1063
1064 2000-11-03  Akim Demaille  <akim@epita.fr>
1065
1066         For some reason, this was not applied.
1067
1068         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

1072

1081         (done): Rename as...
1082         (output_files): this.
1083         Use `obstack_save'.
1084         * src/main.c (main): Don't use `atexit' to register `done', since
1085         it no longer has to remove tmp files, just call `output_files'
1086         when there are no errors.
1087
1088 2000-11-02  Akim Demaille  <akim@epita.fr>
1089

1193         Reported by Piotr Gackiewicz, and fixed by Neil Booth.

1207
1208         * bison.s1 (yyparse): Assign the default value
1209         unconditionally, to avoid a GCC warning and make the parser a
1210         tad smaller.
1211
1212 2000-10-02  Akim Demaille  <akim@epita.fr>
1213

1221
1222 2000-10-02  Akim Demaille  <akim@epita.fr>
1223
1224         The location tracking mechanism is precious for parse error
1225         messages.  Nevertheless, it is enabled only when `@n' is used in
1226         the grammar, which is a different issue (you can use it in error
1227         message, but not in the grammar per se).  Therefore, there should
1228         be another means to enable it.
1229
1230         * src/getargs.c (getargs): Support `--locations'.
1231         (usage): Report it.
1232         * src/getargs.h (locationsflag): Export it.
1233         * src/lex.c (percent_table): Support `%locations'.
1234         * src/reader.c (yylsp_needed): Remove this variable, now replaced
1235         with `locationsflag'.
1236         * doc/bison.texinfo: Document `--locations' and `%locations'.
1237         Sort the options.
1238         * tests/calc.m4: Test it.
1239
1240         For regularity of the names, replace each
1241         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
1242         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
1243         In addition replace each `flag' with `_flag'.
1244
1245 2000-10-02  Akim Demaille  <akim@epita.fr>
1246
1247         Also test parse error messages, including with YYERROR_VERBOSE.
1248
1249         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
1250         associative).
1251         Use it to check the computations.
1252         Use it to check `nonassoc' is honored.
1253         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
1254         `--yyerror-verbose'.
1255         (_AT_CHECK_CALC): Adjust to this option.
1256         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
1257
1258 2000-10-02  Akim Demaille  <akim@epita.fr>
1259
1260         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
1261         the latter demonstrates a flaw in the handling of non debugging
1262         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
1263         was used in order to simplify:
1264
1265         #if YYDEBUG
1266         if (yydebug)
1267         {
1268         ...
1269         }
1270         #endif
1271
1272         into
1273
1274         if (yydebug)
1275         {
1276         ...
1277         }
1278
1279         unfortunately this leads to a CPP conflict when
1280         `--name-prefix=foo' is used since it produces `#define yydebug
1281         foodebug'.
1282
1283         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
1284         (YYDPRINTF): New macro.
1285         Spread its use.
1286         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
1287         the bison options.
1288         Also test `--verbose', `--defines' and `--name-prefix'.
1289
1290 2000-10-02  Akim Demaille  <akim@epita.fr>
1291
1292         Improve the readability of the produced parsers.
1293
1294         * src/bison.s1: Formatting changes.
1295         Improve the comment related to the `$' mark.
1296         (yydefault): Don't fall through to `yyresume': `goto' there.
1297         * src/output.c (output_parser): When the `$' is met, skip the end
1298         of its line.
1299         New variable, `number_of_dollar_signs', to check there's exactly
1300         one `$' in the parser skeleton.
1301
1302 2000-10-02  Akim Demaille  <akim@epita.fr>
1303
1304         * lib/xstrdup.c: New file, from the fileutils.
1305         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
1306         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
1307         instead of strlen + xmalloc + strcpy.
1308         * src/symtab.c (copys): Remove, use xstrdup instead.
1309
1310 2000-10-02  Akim Demaille  <akim@epita.fr>
1311
1312         * src/gram.h (associativity): New enum type which replaces the
1313         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
1314         `right_assoc', `left_assoc' and `non_assoc'.
1315         Adjust all dependencies.
1316         * src/reader.c: Formatting changes.
1317         (LTYPESTR): Don't define it, use it as a literal in
1318         `reader_output_yylsp'.
1319         * src/symtab.h (symbol_class): New enum type which replaces the
1320         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
1321         `sunknown', `stoken and `snterm'.
1322
1323 2000-10-02  Akim Demaille  <akim@epita.fr>
1324
1325         * src/getargs.c (fixed_outfiles): Rename as...

1327         Adjust dependencies.
1328
1329 2000-10-02  Akim Demaille  <akim@epita.fr>
1330
1331         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
1332         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
1333         difficult and introduced a lot of core dump.  It turns out that
1334         Bison used an implementation of `xmalloc' based on `calloc', and
1335         at various places it does depend upon the initialization to 0.  I
1336         have not tried to isolate the pertinent places, and all the former
1337         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
1338         someone should address this issue.
1339
1340         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
1341         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

1434
1435         * src/output.c (token_actions): Introduce a temporary array,

1437         output_short_table.
1438
1439 2000-10-02  Akim Demaille  <akim@epita.fr>
1440
1441         `user_toknums' is output as a `short[]' in `output.c', while it is
1442         defined as a `int[]' in `reader.c'.  For consistency with the
1443         other output tables, `user_toknums' is now defined as a table of
1444         shorts.
1445
1446         * src/reader.c (user_toknums): Be a short table instead of an int

1459         order to get rid of the `static' prototypes.
1460         No longer use `register'.
1461         * src/output.h: New file.

1485         inclusion.
1486         Don't define PARAMS.
1487         * src/system.h: Define PARAMS.
1488         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the

1653
1654 2000-03-17  Akim Demaille  <akim@epita.fr>
1655
1656         On syntax errors, report the token on which we choked.
1657
1658         * src/bison.s1 (yyparse): In the label yyerrlab, when

1676

1678         copy_comment.  Removed now unused `match', `ended',
1679         `cplus_comment'.
1680         (copy_comment, copy_string): Moved, to be visible from
1681         copy_definition.
1682

1684
1685         * src/reader.c (copy_string): Declare `static inline'.  No

1707
1708         Change the handling of @s so that they behave exactly like $s.
1709         There is now a pseudo variable @$ (readble and writable), location
1710         of the lhs of the rule (by default ranging from the location of
1711         the first symbol of the rhs, to the location of the last symbol,
1712         or, if the rhs is empty, YYLLOC).
1713
1714         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
1715         yyval.
1716         (yyparse): When providing a default semantic action, provide a
1717         default location action.
1718         (after the $): No longer change `*YYLSP', just stack YYLOC the
1719         same way you stack YYVAL.
1720         * src/reader.c (read_declarations): Use warns.
1721         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
1722         (copy_action, case '@'): Likewise.
1723         Use a standard error message, to save useless work from
1724         translators.
1725
1726 2000-03-17  Akim Demaille  <akim@epita.fr>
1727

1745
1746         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
1747         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
1748         One `#if YYDEBUG' remains, since it uses variables which are
1749         defined only if `YYDEBUG != 0'.
1750
1751 2000-03-16  Akim Demaille  <akim@epita.fr>

1777         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

1783         the proper line number and file name.
1784         (DEFS): Propagate the location of bison library files and of the
1785         locale files.
1786         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
1787         builddir.
1788         * acinclude.m4: Remove, replaced by the directory m4.
1789         * m4/Makefile.am (EXTRA_DIST): New variable.
1790         * m4/gettext.m4: New file, from the fileutils.
