  75         Attaching lineno to buckets is stupid, since only one copy of each

 195 2001-11-19  Akim Demaille  <akim@epita.fr>
 196
 197         * src/vcg.c: You do the output, so you are responsible of the
 198         handling of VCG syntax, in particular: use quotearg.
 199         * src/print_graph.c: Don't.
 200         (print_actions): Don't output the actions as part of the nodes,
 201         since that's the job of the edges.

 299         * tests/calc.at, tests/output.at, tests/regression.at,
 300         * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
 301         now the tests are run in private dirs, therefore AC_CLEANUP and
 302         family can be simplified to 0-ary.
 303         * tests/atlocal.in: Now that we run `elsewhere' than in tests/,
 304         use abs. path to find config.h.

 307
 308         * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

 311         Reported by Wolfram Wagner.
 312
 313 2001-11-14  Akim Demaille  <akim@epita.fr>
 314
 315         * src/bison.simple (yyparse): Let yyls1, yyss1 and yyvs1 be
 316         defined only if yyoverflow is defined, to avoid `warning: unused
 317         variable `yyvs1''.

 326
 327         * src/lex.c, src/lex.h (token_buffer, unlexed_token_buffer):
 328         Revert a previous patch:  these are really const.
 329         * src/conflicts.c (conflict_report): Additional useless pair of
 330         braces to pacify GCC's warnings for `if () if () {} else {}'.
 331         * src/lex.c (parse_percent_token): Replace equal_offset with
 332         arg_offset.
 333         arg is const.
 334         Be sure to strdup `arg' when used, since there is no reason for
 335         token_buffer not to change.
 336
 337 2001-11-14  Akim Demaille  <akim@epita.fr>
 338

 340         definition.
 341         * src/main.c (main): Use them.
 342         Suggested by Hans Aberg.
 343

 345
 346         Version 1.30b.
 347
 348         * src/system.h (ngettext): Now that we use ngettext, be sure to
 349         provide a default definition when NLS are not used that takes care
 350         of the cardinality.
 351
 352 2001-11-12  Akim Demaille  <akim@epita.fr>
 353
 354         * doc/bison.texinfo: Use `$' as shell prompt, not `%'.

 371         * configure.in (AM_GNU_GETTEXT): Ask for ngettext.
 372         * tests/regression.at (%expect not enough, %expect right)
 373         (%expect too much): New.
 374

1320
1321         * src/reader.c (gensym): `gensym_count' is your own.
1322         Use a static buf to create the symbol name, as token_buffer is no

1326
1327         * src/conflicts.c (conflict_report): Be sure not to append to res
1328         between two calls, which could happen if both first sprintf were

1334         New, from fileutils 4.0.37.
1335         * configure.in: Require Autoconf 2.49c.  I took some time before
1336         making this decision.  This is the only way out for portability
1337         issues in Bison, it would mean way too much duplicate effort to
1338         import in Bison features implemented in 2.49c since 2.13.
1339         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

1352         (init_lex): Initialize it.  No longer call...

1357
1358         * src/lex.h: Rename all the tokens:

1360         s/\bIDENTIFIER\b/tok_identifier/g;
1361         etc.
1362         Let them be enums, not #define, to ease debugging.
1363         Adjust all the code.
1364
1365 2001-01-18  Akim Demaille  <akim@epita.fr>
1366
1367         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.

1369
1370 2001-01-18  Akim Demaille  <akim@epita.fr>
1371
1372         Since we now use obstacks, more % directives can be enabled.
1373
1374         * src/lex.c (percent_table): Also accept `%yacc',
1375         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
1376         `%debug'.
1377         Handle the actions for `%semantic_parser' and `%pure_parser' here,
1378         instead of returning a token.
1379         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
1380         * src/reader.c (read_declarations): Adjust.
1381         * src/files.c (open_files): Don't call `compute_base_names', don't
1382         compute `attrsfile' since they depend upon data which might be
1383         *in* the input file now.
1384         (output_files): Do it here.
1385         * src/output.c (output_headers): Document the fact that this patch
1386         introduces a guaranteed SEGV for semantic parsers.
1387         * doc/bison.texinfo: Document them.

1408
1409         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
1410         (copy_dollar): Now that everything uses obstacks, get rid of the
1411         FILE * parameters.
1412
1413 2000-12-20  Akim Demaille  <akim@epita.fr>
1414
1415         * src/files.c (open_files): Actually the `.output' file is based
1416         on the short_base_name, not base_name.
1417         * tests/suite.at (Checking output file names): Adjust.
1418
1419 2000-12-20  Akim Demaille  <akim@epita.fr>
1420
1421         * src/bison.s1: Remove, we now use directly...

1445         (stringappend): Be just like strcat but allocate.
1446         (base_names): Eve out from open_files.
1447         Try to simplify the rather hairy computation of base_name and
1448         short_base_name.
1449         (open_files): Use it.
1450         * tests/suite.at (Checking output file names): New test.

1460
1461 2000-12-19  Akim Demaille  <akim@epita.fr>

1467
1468 2000-12-19  Akim Demaille  <akim@epita.fr>
1469
1470         Let the handling of the skeleton files be local to the procedures
1471         that use it.

1521
1522         * lib/obstack.h: Formatting changes.
1523         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
1524         prevents type checking.
1525         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
1526         cast the value to (void *): assigning a `foo *' to a `void *'
1527         variable is valid.
1528         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
1529         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

1566

1579         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
1580         `const' their input argument (`data' or `address').

1609         * src/main.c (main): Don't use `atexit' to register `done', since
1610         it no longer has to remove tmp files, just call `output_files'
1611         when there are no errors.
1612
1613 2000-11-02  Akim Demaille  <akim@epita.fr>

1717         `bison -v' segfaults.
1718         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
1719
1720         * tests/regression.m4: New file.

1732
1733         * bison.s1 (yyparse): Assign the default value
1734         unconditionally, to avoid a GCC warning and make the parser a
1735         tad smaller.
1736
1737 2000-10-02  Akim Demaille  <akim@epita.fr>
1738

1743
1744         * src/derives.c, src/print.c, src/reduce.c: To ease the

1746
1747 2000-10-02  Akim Demaille  <akim@epita.fr>
1748
1749         The location tracking mechanism is precious for parse error
1750         messages.  Nevertheless, it is enabled only when `@n' is used in
1751         the grammar, which is a different issue (you can use it in error
1752         message, but not in the grammar per se).  Therefore, there should
1753         be another means to enable it.
1754
1755         * src/getargs.c (getargs): Support `--locations'.
1756         (usage): Report it.
1757         * src/getargs.h (locationsflag): Export it.
1758         * src/lex.c (percent_table): Support `%locations'.
1759         * src/reader.c (yylsp_needed): Remove this variable, now replaced
1760         with `locationsflag'.
1761         * doc/bison.texinfo: Document `--locations' and `%locations'.
1762         Sort the options.
1763         * tests/calc.m4: Test it.
1764
1765         For regularity of the names, replace each
1766         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
1767         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
1768         In addition replace each `flag' with `_flag'.
1769
1770 2000-10-02  Akim Demaille  <akim@epita.fr>
1771
1772         Also test parse error messages, including with YYERROR_VERBOSE.
1773
1774         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
1775         associative).
1776         Use it to check the computations.
1777         Use it to check `nonassoc' is honored.
1778         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
1779         `--yyerror-verbose'.
1780         (_AT_CHECK_CALC): Adjust to this option.
1781         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
1782
1783 2000-10-02  Akim Demaille  <akim@epita.fr>
1784
1785         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
1786         the latter demonstrates a flaw in the handling of non debugging
1787         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
1788         was used in order to simplify:
1789
1790         #if YYDEBUG
1791         if (yydebug)
1792         {
1793         ...
1794         }
1795         #endif
1796
1797         into
1798
1799         if (yydebug)
1800         {
1801         ...
1802         }
1803
1804         unfortunately this leads to a CPP conflict when
1805         `--name-prefix=foo' is used since it produces `#define yydebug
1806         foodebug'.
1807
1808         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
1809         (YYDPRINTF): New macro.
1810         Spread its use.
1811         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
1812         the bison options.
1813         Also test `--verbose', `--defines' and `--name-prefix'.
1814
1815 2000-10-02  Akim Demaille  <akim@epita.fr>
1816
1817         Improve the readability of the produced parsers.
1818
1819         * src/bison.s1: Formatting changes.
1820         Improve the comment related to the `$' mark.
1821         (yydefault): Don't fall through to `yyresume': `goto' there.
1822         * src/output.c (output_parser): When the `$' is met, skip the end
1823         of its line.
1824         New variable, `number_of_dollar_signs', to check there's exactly
1825         one `$' in the parser skeleton.
1826
1827 2000-10-02  Akim Demaille  <akim@epita.fr>
1828
1829         * lib/xstrdup.c: New file, from the fileutils.
1830         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
1831         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
1832         instead of strlen + xmalloc + strcpy.
1833         * src/symtab.c (copys): Remove, use xstrdup instead.
1834
1835 2000-10-02  Akim Demaille  <akim@epita.fr>
1836
1837         * src/gram.h (associativity): New enum type which replaces the
1838         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
1839         `right_assoc', `left_assoc' and `non_assoc'.
1840         Adjust all dependencies.
1841         * src/reader.c: Formatting changes.
1842         (LTYPESTR): Don't define it, use it as a literal in
1843         `reader_output_yylsp'.
1844         * src/symtab.h (symbol_class): New enum type which replaces the
1845         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
1846         `sunknown', `stoken and `snterm'.

1856         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
1857         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
1858         difficult and introduced a lot of core dump.  It turns out that
1859         Bison used an implementation of `xmalloc' based on `calloc', and
1860         at various places it does depend upon the initialization to 0.  I
1861         have not tried to isolate the pertinent places, and all the former
1862         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
1863         someone should address this issue.
1864
1865         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.

1965
1966         `user_toknums' is output as a `short[]' in `output.c', while it is
1967         defined as a `int[]' in `reader.c'.  For consistency with the

2013         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the

2218 2000-03-17  Akim Demaille  <akim@epita.fr>
2219
2220         * src/reader.c (copy_comment): New function, factored out from:
2221         (copy_action): Use it.  Removed now unused `match', `ended',
2222         `cplus_comment'.

2230
2231 2000-03-17  Akim Demaille  <akim@epita.fr>
2232
2233         Change the handling of @s so that they behave exactly like $s.
2234         There is now a pseudo variable @$ (readble and writable), location
2235         of the lhs of the rule (by default ranging from the location of
2236         the first symbol of the rhs, to the location of the last symbol,
2237         or, if the rhs is empty, YYLLOC).
2238
2239         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
2240         yyval.
2241         (yyparse): When providing a default semantic action, provide a
2242         default location action.
2243         (after the $): No longer change `*YYLSP', just stack YYLOC the
2244         same way you stack YYVAL.
2245         * src/reader.c (read_declarations): Use warns.
2246         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
2247         (copy_action, case '@'): Likewise.
2248         Use a standard error message, to save useless work from
2249         translators.
2250
2251 2000-03-17  Akim Demaille  <akim@epita.fr>
2252
2253         * src/bison.s1: Formatting and cosmetics changes.

2270
2271         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
2272         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
2273         One `#if YYDEBUG' remains, since it uses variables which are
2274         defined only if `YYDEBUG != 0'.
2275
2276 2000-03-16  Akim Demaille  <akim@epita.fr>

2300         handled via src/Makefile.am.

2302         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by
2303         autoheader.

2308         the proper line number and file name.
2309         (DEFS): Propagate the location of bison library files and of the
2310         locale files.
2311         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
2312         builddir.
2313         * acinclude.m4: Remove, replaced by the directory m4.
2314         * m4/Makefile.am (EXTRA_DIST): New variable.
2315         * m4/gettext.m4: New file, from the fileutils.

2989         * src/lex.c:
2990         Include getopt.h.  Add some extern decls.
2991         (safegetc): New function to deal with EOF gracefully.
2992         (literalchar); new function to deal with reading \ escapes.
2993         (lex): Use literalchar.
2994         (lex): Implemented "..." tokens.
2995         (literalchar, lex, parse_percent_token): Made tokenbuffer
2996         always contain the token.  This includes growing the token
2997         buffer while reading an integer.

3001         -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
3002         major changes to files.c.
3003         (lex) Retain in the incoming stream a character following
3004         an incorrect '/'.
3005         (skip_white_space, lex):  Revised most error messages

3012          Add faction flag
3013         and actfile file.  Handle noparserflag.  Both for -n switch.
3014
3015         * src/conflicts.c (resolve_sr_conflict):
