 961         bound to true.

 999         with something new. Skeletons are now processed character by character

1330
1331         * src/reader.c (gensym): `gensym_count' is your own.
1332         Use a static buf to create the symbol name, as token_buffer is no

1336
1337         * src/conflicts.c (conflict_report): Be sure not to append to res

1344         New, from fileutils 4.0.37.
1345         * configure.in: Require Autoconf 2.49c.  I took some time before
1346         making this decision.  This is the only way out for portability
1347         issues in Bison, it would mean way too much duplicate effort to
1348         import in Bison features implemented in 2.49c since 2.13.
1349         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

1367
1368         * src/lex.h: Rename all the tokens:

1370         s/\bIDENTIFIER\b/tok_identifier/g;
1371         etc.
1372         Let them be enums, not #define, to ease debugging.
1373         Adjust all the code.
1374
1375 2001-01-18  Akim Demaille  <akim@epita.fr>
1376
1377         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.

1379
1380 2001-01-18  Akim Demaille  <akim@epita.fr>
1381
1382         Since we now use obstacks, more % directives can be enabled.
1383
1384         * src/lex.c (percent_table): Also accept `%yacc',
1385         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
1386         `%debug'.
1387         Handle the actions for `%semantic_parser' and `%pure_parser' here,
1388         instead of returning a token.
1389         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
1390         * src/reader.c (read_declarations): Adjust.
1391         * src/files.c (open_files): Don't call `compute_base_names', don't
1392         compute `attrsfile' since they depend upon data which might be
1393         *in* the input file now.
1394         (output_files): Do it here.
1395         * src/output.c (output_headers): Document the fact that this patch
1396         introduces a guaranteed SEGV for semantic parsers.

1418
1419         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
1420         (copy_dollar): Now that everything uses obstacks, get rid of the
1421         FILE * parameters.
1422
1423 2000-12-20  Akim Demaille  <akim@epita.fr>
1424
1425         * src/files.c (open_files): Actually the `.output' file is based
1426         on the short_base_name, not base_name.
1427         * tests/suite.at (Checking output file names): Adjust.
1428
1429 2000-12-20  Akim Demaille  <akim@epita.fr>
1430
1431         * src/bison.s1: Remove, we now use directly...

1455         (stringappend): Be just like strcat but allocate.
1456         (base_names): Eve out from open_files.
1457         Try to simplify the rather hairy computation of base_name and

1460         * tests/suite.at (Checking output file names): New test.

1479
1480         Let the handling of the skeleton files be local to the procedures

1532         * lib/obstack.h: Formatting changes.
1533         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
1534         prevents type checking.
1535         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
1536         cast the value to (void *): assigning a `foo *' to a `void *'
1537         variable is valid.
1538         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
1539         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

1576

1619         * src/main.c (main): Don't use `atexit' to register `done', since
1620         it no longer has to remove tmp files, just call `output_files'
1621         when there are no errors.
1622
1623 2000-11-02  Akim Demaille  <akim@epita.fr>

1723
1724 2000-10-04  Akim Demaille  <akim@epita.fr>

1726         When a literal string is used to define two different tokens,
1727         `bison -v' segfaults.
1728         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
1729
1730         * tests/regression.m4: New file.

1742
1743         * bison.s1 (yyparse): Assign the default value
1744         unconditionally, to avoid a GCC warning and make the parser a
1745         tad smaller.
1746
1747 2000-10-02  Akim Demaille  <akim@epita.fr>
1748

1756
1757 2000-10-02  Akim Demaille  <akim@epita.fr>
1758
1759         The location tracking mechanism is precious for parse error
1760         messages.  Nevertheless, it is enabled only when `@n' is used in
1761         the grammar, which is a different issue (you can use it in error
1762         message, but not in the grammar per se).  Therefore, there should
1763         be another means to enable it.
1764
1765         * src/getargs.c (getargs): Support `--locations'.
1766         (usage): Report it.
1767         * src/getargs.h (locationsflag): Export it.
1768         * src/lex.c (percent_table): Support `%locations'.
1769         * src/reader.c (yylsp_needed): Remove this variable, now replaced
1770         with `locationsflag'.
1771         * doc/bison.texinfo: Document `--locations' and `%locations'.
1772         Sort the options.
1773         * tests/calc.m4: Test it.
1774
1775         For regularity of the names, replace each
1776         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
1777         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
1778         In addition replace each `flag' with `_flag'.
1779
1780 2000-10-02  Akim Demaille  <akim@epita.fr>
1781
1782         Also test parse error messages, including with YYERROR_VERBOSE.
1783
1784         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
1785         associative).
1786         Use it to check the computations.
1787         Use it to check `nonassoc' is honored.
1788         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
1789         `--yyerror-verbose'.
1790         (_AT_CHECK_CALC): Adjust to this option.
1791         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
1792
1793 2000-10-02  Akim Demaille  <akim@epita.fr>
1794
1795         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
1796         the latter demonstrates a flaw in the handling of non debugging
1797         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
1798         was used in order to simplify:
1799
1800         #if YYDEBUG
1801         if (yydebug)
1802         {
1803         ...
1804         }
1805         #endif
1806
1807         into
1808
1809         if (yydebug)
1810         {
1811         ...
1812         }
1813
1814         unfortunately this leads to a CPP conflict when
1815         `--name-prefix=foo' is used since it produces `#define yydebug
1816         foodebug'.
1817
1818         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
1819         (YYDPRINTF): New macro.
1820         Spread its use.
1821         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
1822         the bison options.
1823         Also test `--verbose', `--defines' and `--name-prefix'.
1824
1825 2000-10-02  Akim Demaille  <akim@epita.fr>
1826

1833         of its line.

1835         one `$' in the parser skeleton.

1840         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
1841         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
1842         instead of strlen + xmalloc + strcpy.

1844
1845 2000-10-02  Akim Demaille  <akim@epita.fr>
1846
1847         * src/gram.h (associativity): New enum type which replaces the
1848         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
1849         `right_assoc', `left_assoc' and `non_assoc'.

1865
1866         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
1867         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
1868         difficult and introduced a lot of core dump.  It turns out that
1869         Bison used an implementation of `xmalloc' based on `calloc', and
1870         at various places it does depend upon the initialization to 0.  I
1871         have not tried to isolate the pertinent places, and all the former
1872         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
1873         someone should address this issue.
1874
1875         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
1876         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

1969
1970         * src/output.c (token_actions): Introduce a temporary array,

1975
1976         `user_toknums' is output as a `short[]' in `output.c', while it is
1977         defined as a `int[]' in `reader.c'.  For consistency with the
1978         other output tables, `user_toknums' is now defined as a table of
1979         shorts.

2023         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the

2025         definitions in config.h.

2187         the file name, not the whole `#line LINE FILE'.
2188
2189 2000-03-17  Akim Demaille  <akim@epita.fr>
2190
2191         On syntax errors, report the token on which we choked.
2192
2193         * src/bison.s1 (yyparse): In the label yyerrlab, when

2208         (warn_banner): Use it.
2209
2210 2000-03-17  Akim Demaille  <akim@epita.fr>
2211
2212         * src/reader.c (copy_definition): Use copy_string and
2213         copy_comment.  Removed now unused `match', `ended',
2214         `cplus_comment'.
2215         (copy_comment, copy_string): Moved, to be visible from
2216         copy_definition.
2217
2218 2000-03-17  Akim Demaille  <akim@epita.fr>
2219
2220         * src/reader.c (copy_string): Declare `static inline'.  No

2242
2243         Change the handling of @s so that they behave exactly like $s.
2244         There is now a pseudo variable @$ (readble and writable), location
2245         of the lhs of the rule (by default ranging from the location of
2246         the first symbol of the rhs, to the location of the last symbol,
2247         or, if the rhs is empty, YYLLOC).
2248
2249         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
2250         yyval.
2251         (yyparse): When providing a default semantic action, provide a
2252         default location action.
2253         (after the $): No longer change `*YYLSP', just stack YYLOC the
2254         same way you stack YYVAL.
2255         * src/reader.c (read_declarations): Use warns.
2256         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
2257         (copy_action, case '@'): Likewise.
2258         Use a standard error message, to save useless work from
2259         translators.
2260
2261 2000-03-17  Akim Demaille  <akim@epita.fr>
2262
2263         * src/bison.s1: Formatting and cosmetics changes.

2270         Makefile now handles them.

2280
2281         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
2282         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
2283         One `#if YYDEBUG' remains, since it uses variables which are
2284         defined only if `YYDEBUG != 0'.
2285
2286 2000-03-16  Akim Demaille  <akim@epita.fr>
2287
2288         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

2310         handled via src/Makefile.am.
2311         (VERSION_STRING, PROTOTYPES, ENABLE_NLS, HAVE_CATGETS,
2312         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by
2313         autoheader.

2318         the proper line number and file name.
2319         (DEFS): Propagate the location of bison library files and of the
2320         locale files.
2321         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
2322         builddir.
2323         * acinclude.m4: Remove, replaced by the directory m4.
2324         * m4/Makefile.am (EXTRA_DIST): New variable.
2325         * m4/gettext.m4: New file, from the fileutils.
